A clinical practice update expert review from the American Gastroenterological Association gives advice on management of endoscopic perforations in the gastrointestinal tract, including esophageal, gastric, duodenal and periampullary, and colon perforation.

There are various techniques for dealing with perforations, including through-the-scope clips (TTSCs), over-the-scope clips (OTSCs), self-expanding metal stents (SEMS), and endoscopic suturing. Newer methods include biological glue and esophageal vacuum therapy. These techniques have been the subject of various retrospective analyses, but few prospective studies have examined their safety and efficacy.

In the expert review, published in Clinical Gastroenterology and Hepatology, authors led by Jeffrey H. Lee, MD, MPH, AGAF, of the department of gastroenterology at the University of Texas MD Anderson Cancer Center, Houston, emphasized that gastroenterologists should have a perforation protocol in place and practice procedures that will be used to address perforations. Endoscopists should also recognize their own limits and know when a patient should be sent to experienced, high-volume centers for further care.

In the event of a perforation, the entire team should be notified immediately, and carbon dioxide insufflation should be used at a low flow setting. The endoscopist should clean up luminal material to reduce the chance of peritoneal contamination, and then treat with an antibiotic regimen that counters gram-negative and anaerobic bacteria.
 

Esophageal perforation

Esophageal perforations most commonly occur during dilation of strictures, endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD). Perforations of the mucosal flap may happen during so-called third-space endoscopy techniques like peroral endoscopic myotomy (POEM). Small perforations can be readily addressed with TTSCs. Larger perforations call for some combination of TTSCs, endoscopic suturing, fibrin glue injection, or esophageal stenting, though the latter is discouraged because of the potential for erosion.

A more concerning complication of POEM is delayed barrier failure, which can cause leaks, mediastinitis, or peritonitis. These complications have been estimated to occur in 0.2%-1.1% of cases.

In the event of an esophageal perforation, the area should be kept clean by suctioning, or by altering patient position if required. Perforations 1-2 cm in size can be closed using OTSCs. Excessive bleeding or larger tears can be addressed using a fully covered SEMS.

Leaks that occur in the ensuing days after the procedure should be closed using TTSCs, OTSCs, or endosuturing, followed by putting in a fully covered stent. Esophageal fistula should be addressed with a fully covered stent with a tight fit.

Endoscopic vacuum therapy is a newer technique to address large or persistent esophageal perforations. A review found it had a 96% success rate for esophageal perforations.
 

Gastric perforations

Gastric perforations often result from peptic ulcer disease or ingestion of something caustic, and it is a high risk during EMR and ESD procedures (0.4%-0.7% intraprocedural risk). The proximal gastric wall isn’t thick as in the gastric antrum, so proximal endoscopic resections require extra care. Lengthy procedures should be done under anesthesia. Ongoing gaseous insufflation during a perforation may worsen the problem because of heightened intraperitoneal pressure. OTSCs may be a better choice than TTSCs for 1-3 cm perforations, while endoloop/TTSC can be used for larger ones.

Duodenal and periampullary perforations

Duodenal and periampullary perforations occur during duodenal stricture dilation, EMR, endoscopic submucosal dissection, endoscopic ultrasound, and endoscopic retrograde cholangiopancreatography (ECRP). The thin duodenal wall makes it more susceptible to perforation than the esophagus, stomach, or colon.

Closing a duodenum perforation can be difficult. Type 1 perforations typically show sudden bleeding and lumen deflation, and often require surgical intervention. Some recent reports have suggested success with TTSCs, OTSCs, band ligation, and endoloops. Type 2 perforations are less obvious, and the endoscopist must examine the gas pattern on fluoroscopic beneath the liver or in the area of the right kidney. Retroperitoneal air following ERCP, if asymptomatic, doesn’t necessarily require intervention.

The challenges presented by the duodenum mean that, for large duodenal polyps, EMR should only be done by experienced endoscopists who are skilled at mucosal closure, and only experts should attempt ESD. Proteolytic enzymes from the pancreas can also pool in the duodenum, which can degrade muscle tissue and lead to delayed perforations. TTSC, OTSC, endosuturing, polymer gels or sheets, and TTSC combined with endoloop cinching have been used to close resection-associated perforations.
 

Colon perforation

Colon perforation may be caused by diverticulitis, inflammatory bowel disease, or occasionally colonic obstruction. Iatrogenic causes are more common and include endoscopic resection, hot forceps biopsy, dilation of stricture resulting from radiation or Crohn’s disease, colonic stenting, and advancement of colonoscope across angulations or into diverticula without straightening the endoscope

Large perforations are usually immediately noticeable and should be treated surgically, as should hemodynamic instability or delayed perforations with peritoneal signs.

Endoscopic closure should be attempted when the perforation site is clean, and lower rectal perforations can generally be repaired with TTSC, OTSC, or endoscopic suturing. In the cecum, or in a torturous or unclean colon, it may be difficult or dangerous to remove the colonoscope and insert an OTSC, and endoscopic suturing may not be possible, making TTSC the only procedure available for right colon perforations. The X-Tack Endoscopic HeliX Tacking System is a recently introduced, through-the-scope technology that places suture-tethered tacks into tissue surrounding the perforation and cinches it together. The system in principle can close large or irregular colonic and small bowel perforations using gastroscopes and colonoscopes, but no human studies have yet been published.
 

Conclusion

This update was a collaborative effort by four endoscopists who felt that it was timely to review the issue of perforations since they can be serious and challenging to manage. The evolution of endoscopic techniques over the last few years, however, has made the closure of spontaneous and iatrogenic perforations much less fear provoking, and they wished to summarize the approaches to a variety of such situations in order to guide practitioners who may encounter them.

“Although perforation is a serious event, with novel endoscopic techniques and tools, the endoscopist should no longer be paralyzed when it occurs,” the authors concluded.

Some authors reported relationships, such as consulting for or royalties from, device companies such as Medtronic and Boston Scientific. The remaining authors disclosed no conflicts.

Homework adherence between behavior therapy sessions is a significant predictor of therapeutic improvement in patients with Tourette’s disorder (TD), a study of 119 youth and adults suggests.

The assigning of “homework” to be completed between sessions – often used in cognitive-behavioral therapy – has been shown to reinforce learning but has not been well studied in TD.

“Understanding the relationship between homework adherence and therapeutic improvement from behavior therapy for TD may offer new insights for enhancing tic severity reductions achieved during this evidence-based treatment,” wrote Joey Ka-Yee Essoe, PhD, of the department of psychiatry and behavioral sciences at Johns Hopkins University, Baltimore, and colleagues.

To conduct the study, published in Behaviour Research and Therapy, the researchers recruited 70 youth and 49 adults with TD, ranging in age from 9 to 67 years, who underwent treatment at a single center. The average age was 21 years, and 80 participants were male. Treatment response was based on the Clinical Global Impressions of Improvement scale (CGI-I). Participants were assessed at baseline for tic severity and received eight sessions over 10 weeks. During those sessions, they were taught to perform a competing response to inhibit the expression of a tic when the tic or urge was detected.

Participants received homework at each weekly therapy session; most consisted of three to four practice sessions of about 30 minutes per week. Therapists reviewed the homework at the following session and adapted as needed to improve tic reduction skills.

After eight sessions of behavior therapy, overall greater homework adherence significantly predicted reduced tic severity and therapeutic improvement. However, early homework adherence predicted therapeutic improvement in youth, while late homework adherence predicted it in adults.

Overall, homework adherence significantly predicted tic reductions, compared with baseline (P = .037), based on the clinician-rated Yale Global Tic Severity Scale.

However, homework adherence dipped midway through treatment in youth and showed a linear decline in adults, the researchers noted.

Among youth, baseline predictors of early homework adherence included lower levels of hyperactivity/impulsivity and caregiver strain. Among adults, baseline predictors of early homework adherence included lower anger scores, less social disability, and greater work disability.

The study findings were limited by several factors, including the absence of complete data on baseline predictors of homework adherence, reliance on a single measure of tic severity and improvement, and reliance on therapists’ reports of homework adherence, the researchers noted.

Future research should include objective measures of homework adherence, such as time-stamped videos, and different strategies may be needed for youth vs. adults, they added.

“Strategies that optimize homework adherence may enhance the efficacy of behavioral therapy, lead to greater tic severity reductions, and higher treatment response rates,” Dr. Essoe and colleagues wrote.

The study was supported by the Tourette Association of America, the National Institute of Mental Health, the American Academy of Neurology, and the American Psychological Foundation.

Melatonin improved sleep time and sleep efficiency in patients with multiple sclerosis (MS) who also had sleep disturbance, according to a new pilot study.

The study included only 30 patients, but the findings suggest that melatonin could potentially help patients with MS who have sleep issues, according to Wan-Yu Hsu, PhD, who presented the study at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).

There is no optimal management of sleep issues for these patients, and objective studies of sleep in patients with MS are scarce, said Dr. Hsu, who is an associate specialist in the department of neurology at the University of California, San Francisco. She worked with Riley Bove, MD, who is an associate professor of neurology at UCSF Weill Institute for Neurosciences.

“Melatonin use was associated with improvement in sleep quality and sleep disturbance in MS patients, although there was no significant change in other outcomes, like daytime sleepiness, mood, and walking ability” Dr. Hsu said in an interview.

Melatonin is inexpensive and readily available over the counter, but it’s too soon to begin recommending it to MS patients experiencing sleep problems, according to Dr. Hsu. “It’s a good start that we’re seeing some effects here with this relatively small group of people. Larger studies are needed to unravel the complex relationship between MS and sleep disturbances, as well as develop successful interventions. But for now, since melatonin is an over-the-counter, low-cost supplement, many patients are trying it already.”

Melatonin regulates the sleep-wake cycle, and previous research has shown a decrease in melatonin serum levels as a result of corticosteroid administration. Other work has suggested that the decline of melatonin secretion in MS may reflect progressive failure of the pineal gland in the pathogenesis of MS. “The cause of sleep problems can be lesions and neural damage to brain structures involved in sleep, or symptoms that indirectly disrupt sleep,” she said.

Indeed, sleep issues in MS are common and wide-ranging, according to Mark Gudesblatt, MD, who was asked to comment on the study. His group previously reported that 65% of people with MS who reported fatigue had undiagnosed obstructive sleep apnea. He also pointed out that disruption of the neural network also disrupts sleep. “That is not only sleep-disordered breathing, that’s sleep onset, REM latency, and sleep efficiency,” said Dr. Gudesblatt, who is medical director of the Comprehensive MS Care Center at South Shore Neurologic Associates in Patchogue, N.Y.

Dr. Gudesblatt cautioned that melatonin, as a dietary supplement, is unregulated. The potency listed on the package may not be accurate and also may not be the correct dose for the patient. “It’s fraught with problems, but ultimately it’s relatively safe,” said Dr. Gudesblatt.

The study was a double-blind, placebo-controlled, crossover study. Participants had a Pittsburgh Sleep Quality Index (PSQI) score of 5 or more, or an Insomnia Severity Index (ISI) score higher than 14 at baseline. Other baseline assessments included patient-reported outcomes for sleep disturbances, sleep quality, daytime sleepiness, fatigue, walking ability, and mood. Half of the participants received melatonin for the first 2 weeks and then switched to placebo. The other half started with placebo and moved over to melatonin at the beginning of week 3.

Participants in the trial started out at 0.5 mg melatonin and were stepped up to 3.0 mg after 3 days if they didn't feel it was working, both when taking melatonin and when taking placebo. Of the 30 patients, 24 stepped up to 3.0 mg when they were receiving melatonin.*

During the second and fourth weeks, participants wore an actigraph watch to measure their physical and sleep activities, and then repeated the patient-reported outcome measures at the end of weeks 2 and 4. Melatonin improved average sleep time (6.96 vs. 6.67 hours; P = .03) as measured by the actigraph watch. Sleep efficiency was also nominally improved (84.7% vs. 83.2%), though the result was not statistically significant (P = .07). Other trends toward statistical significance included improvements in ISI (–3.5 vs. –2.4; P = .07), change in PSQI component 1 (–0.03 vs. 0.0; P = .07), and change in the NeuroQoL-Fatigue score (–4.7 vs. –2.4; P = .06).

Dr. Hsu hopes to conduct larger studies to examine how the disease-modifying therapies might affect the results of the study.

The study was funded by the National Multiple Sclerosis Society. Dr. Hsu and Dr. Gudesblatt have no relevant financial disclosures.

Half of the participants received melatonin for the first 2 weeks and then switched to placebo. The other half started with placebo and moved over to melatonin at the beginning of week 3.

Participants in the trial started out at 0.5 mg melatonin and were stepped up to 3.0 mg after 3 days if they didn't feel it was working, both when taking melatonin and when taking placebo. Of the 30 patients, 24 stepped up to 3.0 mg when they were receiving melatonin.*

During the second and fourth weeks, participants wore an actigraph watch to measure their physical and sleep activities, and then repeated the patient-reported outcome measures at the end of weeks 2 and 4. Melatonin improved average sleep time (6.96 vs. 6.67 hours; P = .03) as measured by the actigraph watch. Sleep efficiency was also nominally improved (84.7% vs. 83.2%), though the result was not statistically significant (P = .07). Other trends toward statistical significance included improvements in ISI (–3.5 vs. –2.4; P = .07), change in PSQI component 1 (–0.03 vs. 0.0; P = .07), and change in the NeuroQoL-Fatigue score (–4.7 vs. –2.4; P = .06).

Dr. Hsu hopes to conduct larger studies to examine how the disease-modifying therapies might affect the results of the study.

Melatonin improved sleep time and sleep efficiency in patients with multiple sclerosis (MS) who also had sleep disturbance, according to a new pilot study.

The study included only 30 patients, but the findings suggest that melatonin could potentially help patients with MS who have sleep issues, according to Wan-Yu Hsu, PhD, who presented the study at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).

There is no optimal management of sleep issues for these patients, and objective studies of sleep in patients with MS are scarce, said Dr. Hsu, who is an associate specialist in the department of neurology at the University of California, San Francisco. She worked with Riley Bove, MD, who is an associate professor of neurology at UCSF Weill Institute for Neurosciences.

“Melatonin use was associated with improvement in sleep quality and sleep disturbance in MS patients, although there was no significant change in other outcomes, like daytime sleepiness, mood, and walking ability” Dr. Hsu said in an interview.

Melatonin is inexpensive and readily available over the counter, but it’s too soon to begin recommending it to MS patients experiencing sleep problems, according to Dr. Hsu. “It’s a good start that we’re seeing some effects here with this relatively small group of people. Larger studies are needed to unravel the complex relationship between MS and sleep disturbances, as well as develop successful interventions. But for now, since melatonin is an over-the-counter, low-cost supplement, many patients are trying it already.”

Melatonin regulates the sleep-wake cycle, and previous research has shown a decrease in melatonin serum levels as a result of corticosteroid administration. Other work has suggested that the decline of melatonin secretion in MS may reflect progressive failure of the pineal gland in the pathogenesis of MS. “The cause of sleep problems can be lesions and neural damage to brain structures involved in sleep, or symptoms that indirectly disrupt sleep,” she said.

Indeed, sleep issues in MS are common and wide-ranging, according to Mark Gudesblatt, MD, who was asked to comment on the study. His group previously reported that 65% of people with MS who reported fatigue had undiagnosed obstructive sleep apnea. He also pointed out that disruption of the neural network also disrupts sleep. “That is not only sleep-disordered breathing, that’s sleep onset, REM latency, and sleep efficiency,” said Dr. Gudesblatt, who is medical director of the Comprehensive MS Care Center at South Shore Neurologic Associates in Patchogue, N.Y.

Dr. Gudesblatt cautioned that melatonin, as a dietary supplement, is unregulated. The potency listed on the package may not be accurate and also may not be the correct dose for the patient. “It’s fraught with problems, but ultimately it’s relatively safe,” said Dr. Gudesblatt.

The study was a double-blind, placebo-controlled, crossover study. Participants had a Pittsburgh Sleep Quality Index (PSQI) score of 5 or more, or an Insomnia Severity Index (ISI) score higher than 14 at baseline. Other baseline assessments included patient-reported outcomes for sleep disturbances, sleep quality, daytime sleepiness, fatigue, walking ability, and mood. Half of the participants received melatonin for the first 2 weeks and then switched to placebo. The other half started with placebo and moved over to melatonin at the beginning of week 3.

Participants in the trial started out at 0.5 mg melatonin and were stepped up to 3.0 mg after 3 days if they didn't feel it was working, both when taking melatonin and when taking placebo. Of the 30 patients, 24 stepped up to 3.0 mg when they were receiving melatonin.*

American children gained a lot of weight in the last year, setting a dangerous trajectory towards metabolic disease that requires urgent policy change, according to a new report from the Robert Wood Johnson Foundation.

“Our nation’s safety net is fragile, outdated, and out of reach for millions of eligible kids and caregivers,” said Jamie Bussel, senior program officer at the RWJF, and senior author of the report. She added that the pandemic further fractured an already broken system that disproportionately overlooks “children of color and those who live farthest from economic opportunity”.
 

It’s time to think ‘bigger and better’

Ms. Bussel said, during a press conference, that congress responded to the pandemic with “an array of policy solutions,” but it’s now time to think ‘bigger and better.’

“There have been huge flexibilities deployed across the safety net program and these have been really important reliefs, but the fact is many of them are temporary emergency relief measures,” she explained.

For the past 3 years, the RWJF’s annual State of Childhood Obesity report has drawn national and state obesity data from large surveys including the National Survey of Children’s Health, the Youth Risk Behavior Surveillance System, the WIC Participant and Program Characteristics Survey, and the National Health and Nutrition Examination Survey.

Similar to in past years, this year’s data show that rates of obesity and overweight have remained relatively steady and have been highest among minority and low-income populations. For example, data from the 2019-2020 National Survey of Children’s Health, along with an analysis conducted by the Health Resources and Services Administration’s Maternal and Child Health Bureau, show that one in six – or 16.2% – of youth aged 10-17 years have obesity.

While non-Hispanic Asian children had the lowest obesity rate (8.1%), followed by non-Hispanic White children (12.1%), rates were significantly higher for Hispanic (21.4%), non-Hispanic Black (23.8%), and non-Hispanic American Indian/Alaska Native (28.7%) children, according to the report.

“Additional years of data are needed to assess whether obesity rates changed after the onset of the pandemic,” explained Ms. Bussel.
 

Digging deeper

Other studies included in this year’s report were specifically designed to measure the impact of the pandemic, and show a distinct rise in overweight and obesity, especially in younger children. For example, a retrospective cohort study using data from Kaiser Permanente Southern California showed the rate of overweight and obesity in children aged 5-11 years rose to 45.7% between March 2020 and January 2021, up from 36.2% before the pandemic.

Another of these studies, which was based on national electronic health records of more than 430,000 children, showed the obesity rate crept from 19.3% to 22.4% between August 2019 and August 2020.

“The lid we had been trying desperately to put on the obesity epidemic has come off again,” said Sandra G Hassink, MD, MSc, who is medical director of the American Academy of Pediatrics Institute for Healthy Childhood Weight.

“In the absence of COVID we had been seeing slow upticks in the numbers – and in some groups we’d been thinking maybe we were headed toward stabilization – but these numbers blow that out of the water ... COVID has escalated the rates,” she said in an interview.

“Unfortunately, these two crises – the COVID pandemic, the childhood obesity epidemic – in so many ways have exacerbated one another,” said Ms. Bussel. “It’s not a huge surprise that we’re seeing an increase in childhood obesity rates given the complete and utter disruption of every single system that circumscribes our lives.”
 

The systems that feed obesity

Addressing childhood obesity requires targeting far beyond healthy eating and physical activity, Ms. Bussel said.

“As important is whether that child has a safe place to call home. Does mom or dad or their care provider have a stable income? Is there reliable transportation? Is their access to health insurance? Is there access to high-quality health care? ... All of those factors influence the child and the family’s opportunities to live well, be healthy, and be at a healthy weight,” she noted.

The report includes a list of five main policy recommendations.

• Making free, universal school meal programs permanent.
• Extending eligibility for WIC, the Special Supplemental Nutrition Program for Women, Infants, and Children, to postpartum mothers and to children through age 6.
• Extending and expanding other programs, such as the Child Tax Credit.
• Closing the Medicaid coverage gap.
• Developing a consistent approach to collecting obesity data organized by race, ethnicity, and income level.

“Collectively, over at least the course of the last generation or two, our policy approach to obesity prevention has not been sufficient. But that doesn’t mean all of our policy approaches have been failures,” Ms. Bussel said during an interview. “Policy change does not always need to be dramatic to have a real impact on families.”

Fighting complacency

For Dr. Hassink, one of the barriers to change is society’s level of acceptance. She said an identifiable explanation for pandemic weight gain doesn’t mean society should simply shrug it off.

“If we regarded childhood obesity as the population level catastrophe that it is for chronic disease maybe people would be activated around these policy changes,” she said.

“We’re accepting a disease process that wreaks havoc on people,” noted Dr. Hassink, who was not involved in the new report. “I think it’s hard for people to realize the magnitude of the disease burden that we’re seeing. If you’re in a weight management clinic or any pediatrician’s office you would see it – you would see kids coming in with liver disease, 9-year-olds on [continuous positive airway pressure] for sleep apnea, kids needing their hips pinned because they had a hip fracture because of obesity.

“So, those of us that see the disease burden see what’s behind those numbers. The sadness of what we’re talking about is we know a lot about what could push the dial and help reduce this epidemic and we’re not doing what we already know,” added Dr. Hassink.

Ms. Bussel and Dr. Hassink reported no conflicts.

Children in foster care are far more likely to be prescribed psychotropic medication, compared with children who are not in foster care, an analysis of Medicaid claims data shows.

Different rates of mental health disorders in these groups do not fully explain the “alarming trend,” which persists across psychotropic medication classes, said study author Rachael J. Keefe, MD, MPH.

Misdiagnosis, overprescribing, and frequent transitions to new doctors may contribute to this phenomenon, doctors suggested.

Dr. Keefe, with Baylor College of Medicine, Houston, and colleagues analyzed Medicaid claims data from two managed care organizations to compare the prevalence of psychotropic medication use among children in foster care versus children insured by Medicaid but not in foster care. The study focused on claims from the same region in southeast Texas between July 2014 and June 2016.

The researchers included 388,914 children in Medicaid and 8,426 children in foster care in their analysis. They excluded children with a seizure or epilepsy diagnosis.

About 8% of children not in foster care received psychotropic medications, compared with 35% of those in foster care.

Children in foster care were 27 times more likely to receive antipsychotic medication (21.2% of children in foster care vs. 0.8% of children not in foster care) and twice as likely to receive antianxiety medication (6% vs. 3%).

For children in foster care, the rate of alpha-agonist use was 15 times higher, the rate of antidepressant use was 13 times higher, the rate of mood stabilizer use was 26 times higher, and the rate of stimulant use was 6 times higher.

The researchers have a limited understanding of the full context in which these medications were prescribed, and psychotropic medications have a role in the treatment of children in foster care, Dr. Keefe acknowledged.

“We have to be careful not to have a knee-jerk reaction” and inappropriately withhold medication from children in foster care, she said in an interview.

But overprescribing has been a concern. Dr. Keefe leads a foster care clinical service at Texas Children’s Hospital in Houston.

“The overprescribing of psychotropic medications to children in foster care is something I feel every day in my clinical practice, but it’s different to see it on paper,” Dr. Keefe said in a news release highlighting the research, which she presented on Oct. 11 at the annual meeting of the American Academy of Pediatrics. “It’s especially shocking to see these dramatic differences in children of preschool and elementary age.”

Misdiagnosis can be a common problem among children in foster care, said Danielle Shaw, MD, a child and adolescent psychiatrist in Camarillo, Calif., during a question-and-answer period following the presentation.

“I see incorrect diagnoses very frequently,” Dr. Shaw said. “The history of trauma or [adverse childhood experiences] is not even included in the assessment. Mood lability from trauma is misdiagnosed as bipolar disorder, despite not meeting criteria. This will justify the use of antipsychotic medication and mood stabilizers. Flashbacks can be mistaken for a psychotic disorder, which again justifies the use of antipsychotic medication.”

Children in foster care have experienced numerous traumatic experiences that affect brain development and the hypothalamic-pituitary-adrenal axis, Dr. Keefe said.

“Although from previous research we know that children in foster care are more likely to carry mental health and developmental disorder diagnoses, this does not account for the significant difference in prescribing practices in this population,” Dr. Keefe said in an interview.

Although the study focused on data in Texas, Dr. Keefe expects similar patterns exist in other regions, based on anecdotal reports. “I work with foster care pediatricians across the country, and many have seen similar concerning trends within their own clinical practices,” she said.

The use of appropriate therapies, minimizing transitions between providers, improved record keeping, the development of deprescribing algorithms, and placement of children in foster care in long-term homes as early as possible are measures that potentially could reduce inappropriate psychotropic prescribing for children in foster care, Dr. Keefe suggested.

The research was funded by a Texas Medical Center Health Policy Research Grant. The study authors and Dr. Shaw had no relevant financial disclosures.

Misdiagnosis can be a common problem among children in foster care, said Danielle Shaw, MD, a child and adolescent psychiatrist in Camarillo, Calif., during a question-and-answer period following the presentation.

“I see incorrect diagnoses very frequently,” Dr. Shaw said. “The history of trauma or [adverse childhood experiences] is not even included in the assessment. Mood lability from trauma is misdiagnosed as bipolar disorder, despite not meeting criteria. This will justify the use of antipsychotic medication and mood stabilizers. Flashbacks can be mistaken for a psychotic disorder, which again justifies the use of antipsychotic medication.”

Children in foster care have experienced numerous traumatic experiences that affect brain development and the hypothalamic-pituitary-adrenal axis, Dr. Keefe said.

“Although from previous research we know that children in foster care are more likely to carry mental health and developmental disorder diagnoses, this does not account for the significant difference in prescribing practices in this population,” Dr. Keefe said in an interview.

Although the study focused on data in Texas, Dr. Keefe expects similar patterns exist in other regions, based on anecdotal reports. “I work with foster care pediatricians across the country, and many have seen similar concerning trends within their own clinical practices,” she said.

The use of appropriate therapies, minimizing transitions between providers, improved record keeping, the development of deprescribing algorithms, and placement of children in foster care in long-term homes as early as possible are measures that potentially could reduce inappropriate psychotropic prescribing for children in foster care, Dr. Keefe suggested.

The research was funded by a Texas Medical Center Health Policy Research Grant. The study authors and Dr. Shaw had no relevant financial disclosures.

The melatonin precursor tryptophan, an amino acid essential in the human diet, has been shown to display antioxidant effects.¹ FICZ (also known as 6-formylindolo[3,2-b]carbazole) is a photoproduct of tryptophan that is engendered by exposure to UVB.² This column discusses the beneficial and detrimental influence of FICZ in skin health.

Antioxidant activity

In 2005, Trommer and Neubert devised a skin lipid model system to screen 47 various compounds (drugs, plant extracts, other plant constituents, and polysaccharides) for topical antioxidative activity in response to UV-induced lipid peroxidation. Among the drugs evaluated, they observed that tryptophan exerted antioxidant effects.³

Wound healing potential

A murine study by Bandeira et al. in 2015 revealed that tryptophan-induced mitigation of the inflammatory response and indoleamine 2, 3-dioxygenase expression may have enhanced skin wound healing in mice who were repeatedly stressed.⁴

Antifibrotic activity

In 2018, Murai et al. endeavored to clarify the role of FICZ in regulating the expression of matrix metalloproteinases and tissue inhibitors of metalloproteinases in normal human dermal fibroblasts. They found that FICZ assists in imparting UV-mediated antifibrotic effects through the AHR/MEK/ERK signal pathway in normal human dermal fibroblasts and, thus, shows promise as a therapeutic option for scleroderma.⁵

Cutaneous leishmaniasis

In 2019, Rodrigues et al. conducted a quantitative analysis of the relative expression of 170 genes involved in various biological processes in the skin biopsies from patients with cutaneous leishmaniasis caused by infection with either Leishmania major or L. tropica. They identified tryptophan-2,3-deoxygenase as a restriction factor for the disorder.⁶

Photosensitizing activity

Park et al. showed that FICZ, a tryptophan photoproduct and endogenous high-affinity aryl hydrocarbon receptor (AhR) agonist, exhibits nanomolar photodynamic activity as a UVA photosensitizer in epidermal keratinocytes and, thus, is possibly operative in human skin.⁷ Syed and Mukhtar add that FICZ is effective at nanomolar concentrations and that future research may elucidate its applicability against UV-induced adverse effects and inflammatory skin conditions.⁸

FICZ, oxidative stress, and cancer promotion

FICZ is known to display detrimental, as well as beneficial, influences in skin. The tryptophan photoproduct, comparable to UVB, ligates AhR, generates reactive oxygen species, and strongly photosensitizes for UVA. As Furue et al. note, FICZ upregulates the expression of terminal differentiation molecules (i.e., filaggrin and loricrin via AhR), and its application has been shown to suppress cutaneous inflammation in a psoriasis and dermatitis mouse model.²

In 2016, Reid et al. reported that the protein photodamage brought about by endogenous photosensitizers such as tryptophan tyrosine residues can contribute to the deleterious impact of UVA on human skin.⁹

In 2018, Tanaka et al. showed that FICZ imparts a cascade of events tantamount in some cases to UVB, as it promoted the synthesis of proinflammatory cytokines such as interleukin (IL)-1 alpha, IL-1 beta, and IL-6 and boosted reactive oxygen species generation in human HaCaT keratinocytes in an AhR-dependent fashion. They concluded that observing FICZ activity contributes to the understanding of how UVB damages organisms.¹⁰

That same year, Murai et al. assessed the effects of FICZ on TGF-beta-mediated ACTA2 and collagen I expression in normal human dermal fibroblasts. They determined that it may act as a key chromophore and one approach to mitigating the effects of photoaging may be to downregulate FICZ signaling.¹¹

A year earlier, Brem et al. showed that the combined effect of FICZ and UVA engendered significant protein damage in HaCaT human keratinocytes, with the oxidation yielded from the combination of FICZ and UVA blocking the removal of potentially mutagenic UVB-induced DNA photolesions by nucleotide excision repair. The researchers concluded that the development of FICZ may raise the risk of incurring skin cancer resulting from sun exposure via the promotion of photochemical impairment of the nucleotide excision repair proteome, which in turn inhibits the removal of UVB-induced DNA lesions.¹²

Conclusion

Tryptophan, an essential amino acid in the human diet, is known to exhibit antioxidant activity. It is also a precursor to the hormone melatonin, which plays an important role in human health. However, the tryptophan photoproduct FICZ, which results from UVB exposure, presents as a complicated substance, conferring healthy and harmful effects. Much more research is necessary to determine how best to harness and direct the useful activities of tryptophan and FICZ without incurring damaging effects. Nanotechnology may be one useful avenue of investigation for this purpose.

Andrea Rapkin, MD, is Board Certified by the American College of Obstetricians and Gynecologists (of which she is also a fellow). After obtaining her MD, she completed her residency in OBGYN at UCLA then joined the faculty at UCLA and is a Professor of Obstetrics and Gynecology. She was one of the first Obstetrician-Gynecologists to adapt the multidisciplinary pain management approach to the evaluation and treatment of women with pelvic and vulvar pain.

You are the founder and director of a clinic focused on a multidisciplinary pain management approach to the evaluation and treatment of women with pelvic and vulvar pain. How did you identify such a clinic as a therapeutic need for patients? 

Dr. Rapkin: The short answer is that a significant proportion of women were not experiencing pain relief or had incomplete relief with traditional medical or surgical therapy. At the time, we also identified various red flags for traditional treatment failures. These red flags included the following: pain of greater than 6 months duration, pain out of proportion to pathology found on examination, multiple visceral and somatic complaints, and psychosocial abnormalities. We now understand more about the neurobiology underpinning these red flags.  

With the widespread availability of laparoscopy in the late 70s and early 80s, many studies investigated the relationship between endometriosis lesions and pain. The general consensus is that there is no relationship between the location or severity of the endometriosis lesions or the disease stage (American Society for Reproductive Medicine staging) with type of symptoms, symptom severity, treatment response, recurrence, or even prognosis. In fact, pain recurrence after adequate surgical treatment is unrelated to the presence of endometriosis lesions found at the time of repeat laparoscopy. This lack of association between pain and presence of visible disease was supported by a recent New England Journal of Medicine article by Zondervan and colleagues demonstrating that up to 30% of women with chronic pelvic pain, present after excision of endometriotic lesions, become unresponsive to conventional treatment.

The neurobiological responses in an individual with chronic pain are more complicated than those seen in the setting of acute pain. Chronic pain may be triggered or maintained by an inflammatory process such as endometriosis but, over time, altered neural processing and psychosocial maladaptation can occur. The altered processing consists of both peripheral and central sensitization which change the way sensory information from the pelvic viscera and surrounding somatic structures in the periphery is transmitted and interpreted in the central nervous system (spinal cord and brain). Visceral pelvic pain can emanate from the uterus, ovaries and fallopian tubes, the urinary bladder, and the bowel, while the somatic sources include the surrounding abdominal wall, low back and pelvic floor muscles, and fascia, and bones. Signal amplification or peripheral sensitization in the pelvic region in women with endometriosis starts with localized inflammation, neovascularization, invasion and innervation of endometriotic implants. As the pelvic organs share thoracolumbar and sacral autonomic neural pathways, inflammation or dysfunction in one organ or tissue, such as the uterus, over time can sensitize or lead to dysfunction in other pelvic organs, such as the bladder or bowel (called viscero-visceral cross sensitization). Finally, somatic structures sharing intervention with the pelvic viscera, such as the fascia and muscles of the lower abdomen, pelvic floor lower back also become sources of pain because of a process called viscero-somatic sensitization. Women who have endometriosis are therefore more likely to experience IBS, bladder pain syndrome/interstitial cystitis and vulvodynia, and up to 80% of individuals can develop myofascial pain related to trigger points and muscle dysfunction. Up to 50% of women with bladder pain have endometriosis. Those with endometriosis or bladder pain are 2.5 times more likely to also have IBS. 

Over time, other visceral and somatic structures innervated by higher levels of the spinal cord can be affected, leading to more widespread pain. Central sensitization manifests as an amplification of pain in the spinal cord and brain. The presence of more than two chronic “unexplained” pain conditions, such as chronic pelvic pain, vulvodynia, myofascial pain, headache, etc suggest the presence of central sensitization. Anxiety, depression, and maladaptive coping strategies often ensue. Functional MRI studies have documented altered central processing in the brain in many chronic pain states including endometriosis. Interdisciplinary therapy including physical therapy, mental health, and pain management/anesthesiology is more effective compared with medical and or surgical therapy alone for endometriosis-related pain in the setting of peripheral and central sensitization.

What should clinicians look for, or what stands out to them, to confirm the endometriosis diagnosis when pain is the presenting symptom?

Dr. Rapkin: There are no pathognomonic symptoms or biomarkers for endometriosis; however, the following historical features have been shown to be linked with a greater likelihood of finding endometriosis:

• persistent dysmenorrhea (menstrual pain) despite NSAID and hormonal treatment
• cyclical pain that is premenstrual and menstrual that progresses to chronic pain or is accompanied by abnormal or heavy menstrual bleeding
• deep dyspareunia
• dyschezia (pain with bowel movements), and sometimes bloating.

An individual with menstrual pain since menarche can have up to a 5% increased risk of endometriosis. Endometriosis in a first-degree relative elevates the risk for endometriosis by 7% to 10%.

Given the complexity of chronic pain, it is important not to assume endometriosis is the only source of pain. All the pelvic visceral and somatic structures should be evaluated. A thorough history addresses all the patient’s symptoms, including vaginal, gastrointestinal and genitourinary. Aggravating factors such as menstrual cycle, bowel and bladder functioning, physical activity, sexual intercourse and stress should be queried. In addition, assessment of mood, anxiety or depression, sleep disturbance and effect of pain on daily functioning are relevant as is history of abuse or trauma (physical, sexual or emotional). This history can be lengthy, so a detailed pain questionnaire is helpful. (See the pelvicpain.org website for a user-friendly pain questionnaire).

With the previously mentioned risk factors in mind, and after a thorough history has been obtained, a pain-localizing exam should be conducted including the abdominal wall, pelvic floor, and then the bimanual and rectovaginal exams for the abdominal wall myofascial/neuropathic pain assessment for which Carnett’s test can be very useful—tender points on the abdominal wall are palpitated and the patient is asked to give a numerical rating of the pain (1-10/10) and marked with a pen. The patient is then asked to either perform a bilateral straight leg raise or an abdominal crunch, and the areas are re-palpitated. If the marked areas are more painful to palpation during the abdominal crunch or the bilateral straight leg raise, it suggests an abdominal wall pain (myofascial or neuropathic) or component of the pain. Similarly, pelvic floor muscles should be assessed after the abdominal wall exam is completed. This is best accomplished with a unit-digital exam with palpation of pelvic muscles for tenderness and hypertonia on exam. These myofascial findings are often present in the setting of endometriosis, but they can be primary-unrelated to presence or absence of endometriosis.

What are your focused disciplines for approaching endometriosis-associated pain? How do you recommend these clinicians or specialists come together to effectively manage a patient’s conditions? 

Dr. Rapkin: The gynecologist or primary care provider can address the chronic inflammatory, estrogen-dependent aspect of endometriosis. Begin with nonsteroidal, anti-inflammatory medication and combined estrogen-progestin or high-dose progestin-alone hormonal therapy to lower estrogenic stimulation of lesions and decidualize those progestin-sensitive lesions. For menstrual cycle related pain (luteal periovulatory or menstrual phase) cyclical exacerbation of other chronic pain conditions, early intervention is recommended. Adequately dosed preemptive nonsteroidal inflammatory agents and, if not tolerated or effective, begin combined hormonal contraceptives or intrauterine or higher dose progestins menstrual suppression, with either continuous monophasic hormonal contraceptives or progestins, is very important for pain that is cyclical or exacerbated in a cyclical fashion. Progestins can be administered orally, such as norethindrone acetate; intramuscularly or subdermally (depot medroxyprogesterone acetate or etonogestrel implant); or intrauterine (which does not lower estrogen levels but can be therapeutic for suppression of menses and local treatment of endometriosis). Failure of hormonal therapy and management of other co-occurring pain conditions warrants trial of a second-line medical therapy such as gonadotropin-releasing hormone antagonist or agonist or surgery for definitive diagnosis and surgical ablation or excision of endometriosis lesions.

I would suggest that gynecologists who treat women with endometriosis and chronic pain try to build a team in their geographic area. Relevant specialists for an interdisciplinary approach include:

• Pelvic floor physical therapist to evaluate and address myofascial dysfunction and pain and voiding abnormalities, such as urinary urgency or frequency and constipation
• Gastroenterologist for evaluation and treatment of irritable bowel or functional abdominal pain and bloating syndrome or inflammatory bowel disease. Urologist or urogynecologist to assess and treat bladder pain syndrome/interstitial cystitis
• Primary care evaluation for diffuse myofascial pain, fibromyalgia, arthralgias, and other inflammatory conditions, and for management of headache and migraine. Rheumatology and neurology specialists may be needed
• Mental health providers for treatment of anxiety, depression, or PTSD and to address stress management, coping skills and provide cognitive behavioral therapy
• Interventional pain management specialist such as physical medicine and rehabilitation (PM and R), pain anesthiologist, neurologist or interventional radiologist to provide relevant nerve blocks, trigger point injections, or botulinum toxin injection.
• Gynecologists experienced in the management of chronic pelvic pain also provide nerve blocks, trigger point and botulinum toxin injections.

Visceral pelvic pain can emanate from the uterus, ovaries and fallopian tubes, the urinary bladder, and the bowel, while the somatic sources include the surrounding abdominal wall, low back and pelvic floor muscles, and fascia, and bones. Signal amplification or peripheral sensitization in the pelvic region in women with endometriosis starts with localized inflammation, neovascularization, invasion and innervation of endometriotic implants. As the pelvic organs share thoracolumbar and sacral autonomic neural pathways, inflammation or dysfunction in one organ or tissue, such as the uterus, over time can sensitize or lead to dysfunction in other pelvic organs, such as the bladder or bowel (called viscero-visceral cross sensitization). Finally, somatic structures sharing intervention with the pelvic viscera, such as the fascia and muscles of the lower abdomen, pelvic floor lower back also become sources of pain because of a process called viscero-somatic sensitization. Women who have endometriosis are therefore more likely to experience IBS, bladder pain syndrome/interstitial cystitis and vulvodynia, and up to 80% of individuals can develop myofascial pain related to trigger points and muscle dysfunction. Up to 50% of women with bladder pain have endometriosis. Those with endometriosis or bladder pain are 2.5 times more likely to also have IBS. 

Over time, other visceral and somatic structures innervated by higher levels of the spinal cord can be affected, leading to more widespread pain. Central sensitization manifests as an amplification of pain in the spinal cord and brain. The presence of more than two chronic “unexplained” pain conditions, such as chronic pelvic pain, vulvodynia, myofascial pain, headache, etc suggest the presence of central sensitization. Anxiety, depression, and maladaptive coping strategies often ensue. Functional MRI studies have documented altered central processing in the brain in many chronic pain states including endometriosis. Interdisciplinary therapy including physical therapy, mental health, and pain management/anesthesiology is more effective compared with medical and or surgical therapy alone for endometriosis-related pain in the setting of peripheral and central sensitization.

What should clinicians look for, or what stands out to them, to confirm the endometriosis diagnosis when pain is the presenting symptom?

Dr. Rapkin: There are no pathognomonic symptoms or biomarkers for endometriosis; however, the following historical features have been shown to be linked with a greater likelihood of finding endometriosis:

• persistent dysmenorrhea (menstrual pain) despite NSAID and hormonal treatment
• cyclical pain that is premenstrual and menstrual that progresses to chronic pain or is accompanied by abnormal or heavy menstrual bleeding
• deep dyspareunia
• dyschezia (pain with bowel movements), and sometimes bloating.

An individual with menstrual pain since menarche can have up to a 5% increased risk of endometriosis. Endometriosis in a first-degree relative elevates the risk for endometriosis by 7% to 10%.

Given the complexity of chronic pain, it is important not to assume endometriosis is the only source of pain. All the pelvic visceral and somatic structures should be evaluated. A thorough history addresses all the patient’s symptoms, including vaginal, gastrointestinal and genitourinary. Aggravating factors such as menstrual cycle, bowel and bladder functioning, physical activity, sexual intercourse and stress should be queried. In addition, assessment of mood, anxiety or depression, sleep disturbance and effect of pain on daily functioning are relevant as is history of abuse or trauma (physical, sexual or emotional). This history can be lengthy, so a detailed pain questionnaire is helpful. (See the pelvicpain.org website for a user-friendly pain questionnaire).

With the previously mentioned risk factors in mind, and after a thorough history has been obtained, a pain-localizing exam should be conducted including the abdominal wall, pelvic floor, and then the bimanual and rectovaginal exams for the abdominal wall myofascial/neuropathic pain assessment for which Carnett’s test can be very useful—tender points on the abdominal wall are palpitated and the patient is asked to give a numerical rating of the pain (1-10/10) and marked with a pen. The patient is then asked to either perform a bilateral straight leg raise or an abdominal crunch, and the areas are re-palpitated. If the marked areas are more painful to palpation during the abdominal crunch or the bilateral straight leg raise, it suggests an abdominal wall pain (myofascial or neuropathic) or component of the pain. Similarly, pelvic floor muscles should be assessed after the abdominal wall exam is completed. This is best accomplished with a unit-digital exam with palpation of pelvic muscles for tenderness and hypertonia on exam. These myofascial findings are often present in the setting of endometriosis, but they can be primary-unrelated to presence or absence of endometriosis.

What are your focused disciplines for approaching endometriosis-associated pain? How do you recommend these clinicians or specialists come together to effectively manage a patient’s conditions? 

Dr. Rapkin: The gynecologist or primary care provider can address the chronic inflammatory, estrogen-dependent aspect of endometriosis. Begin with nonsteroidal, anti-inflammatory medication and combined estrogen-progestin or high-dose progestin-alone hormonal therapy to lower estrogenic stimulation of lesions and decidualize those progestin-sensitive lesions. For menstrual cycle related pain (luteal periovulatory or menstrual phase) cyclical exacerbation of other chronic pain conditions, early intervention is recommended. Adequately dosed preemptive nonsteroidal inflammatory agents and, if not tolerated or effective, begin combined hormonal contraceptives or intrauterine or higher dose progestins menstrual suppression, with either continuous monophasic hormonal contraceptives or progestins, is very important for pain that is cyclical or exacerbated in a cyclical fashion. Progestins can be administered orally, such as norethindrone acetate; intramuscularly or subdermally (depot medroxyprogesterone acetate or etonogestrel implant); or intrauterine (which does not lower estrogen levels but can be therapeutic for suppression of menses and local treatment of endometriosis). Failure of hormonal therapy and management of other co-occurring pain conditions warrants trial of a second-line medical therapy such as gonadotropin-releasing hormone antagonist or agonist or surgery for definitive diagnosis and surgical ablation or excision of endometriosis lesions.

I would suggest that gynecologists who treat women with endometriosis and chronic pain try to build a team in their geographic area. Relevant specialists for an interdisciplinary approach include:

• Pelvic floor physical therapist to evaluate and address myofascial dysfunction and pain and voiding abnormalities, such as urinary urgency or frequency and constipation
• Gastroenterologist for evaluation and treatment of irritable bowel or functional abdominal pain and bloating syndrome or inflammatory bowel disease. Urologist or urogynecologist to assess and treat bladder pain syndrome/interstitial cystitis
• Primary care evaluation for diffuse myofascial pain, fibromyalgia, arthralgias, and other inflammatory conditions, and for management of headache and migraine. Rheumatology and neurology specialists may be needed
• Mental health providers for treatment of anxiety, depression, or PTSD and to address stress management, coping skills and provide cognitive behavioral therapy
• Interventional pain management specialist such as physical medicine and rehabilitation (PM and R), pain anesthiologist, neurologist or interventional radiologist to provide relevant nerve blocks, trigger point injections, or botulinum toxin injection.
• Gynecologists experienced in the management of chronic pelvic pain also provide nerve blocks, trigger point and botulinum toxin injections.

Andrea Rapkin, MD, is Board Certified by the American College of Obstetricians and Gynecologists (of which she is also a fellow). After obtaining her MD, she completed her residency in OBGYN at UCLA then joined the faculty at UCLA and is a Professor of Obstetrics and Gynecology. She was one of the first Obstetrician-Gynecologists to adapt the multidisciplinary pain management approach to the evaluation and treatment of women with pelvic and vulvar pain.

You are the founder and director of a clinic focused on a multidisciplinary pain management approach to the evaluation and treatment of women with pelvic and vulvar pain. How did you identify such a clinic as a therapeutic need for patients? 

Dr. Rapkin: The short answer is that a significant proportion of women were not experiencing pain relief or had incomplete relief with traditional medical or surgical therapy. At the time, we also identified various red flags for traditional treatment failures. These red flags included the following: pain of greater than 6 months duration, pain out of proportion to pathology found on examination, multiple visceral and somatic complaints, and psychosocial abnormalities. We now understand more about the neurobiology underpinning these red flags.  

With the widespread availability of laparoscopy in the late 70s and early 80s, many studies investigated the relationship between endometriosis lesions and pain. The general consensus is that there is no relationship between the location or severity of the endometriosis lesions or the disease stage (American Society for Reproductive Medicine staging) with type of symptoms, symptom severity, treatment response, recurrence, or even prognosis. In fact, pain recurrence after adequate surgical treatment is unrelated to the presence of endometriosis lesions found at the time of repeat laparoscopy. This lack of association between pain and presence of visible disease was supported by a recent New England Journal of Medicine article by Zondervan and colleagues demonstrating that up to 30% of women with chronic pelvic pain, present after excision of endometriotic lesions, become unresponsive to conventional treatment.

The neurobiological responses in an individual with chronic pain are more complicated than those seen in the setting of acute pain. Chronic pain may be triggered or maintained by an inflammatory process such as endometriosis but, over time, altered neural processing and psychosocial maladaptation can occur. The altered processing consists of both peripheral and central sensitization which change the way sensory information from the pelvic viscera and surrounding somatic structures in the periphery is transmitted and interpreted in the central nervous system (spinal cord and brain). Visceral pelvic pain can emanate from the uterus, ovaries and fallopian tubes, the urinary bladder, and the bowel, while the somatic sources include the surrounding abdominal wall, low back and pelvic floor muscles, and fascia, and bones. Signal amplification or peripheral sensitization in the pelvic region in women with endometriosis starts with localized inflammation, neovascularization, invasion and innervation of endometriotic implants. As the pelvic organs share thoracolumbar and sacral autonomic neural pathways, inflammation or dysfunction in one organ or tissue, such as the uterus, over time can sensitize or lead to dysfunction in other pelvic organs, such as the bladder or bowel (called viscero-visceral cross sensitization). Finally, somatic structures sharing intervention with the pelvic viscera, such as the fascia and muscles of the lower abdomen, pelvic floor lower back also become sources of pain because of a process called viscero-somatic sensitization.

Up to 50% of women with bladder pain have endometriosis. Those with endometriosis or bladder pain are 2.5 times more likely to also have IBS.

Central sensitization manifests as an amplification of pain in the spinal cord and brain. The presence of more than two chronic “unexplained” pain conditions, such as chronic pelvic pain, vulvodynia, myofascial pain, headache, etc suggest the presence of central sensitization.

Many pediatric patients with headache experienced increased headache frequency, increased anxiety, and worsening mood through the first year of the COVID-19 pandemic, a newly released survey finds. But some actually found the pandemic era to be less stressful since they were tightly wound and could more easily control their home environments, a researcher said.

“We need to be very mindful of the connections between school and home environments – and social situations – and how they impact headache frequency,” said Marc DiSabella, DO, a pediatric neurologist at Children’s National Hospital/George Washington University, Washington. He is coauthor of a poster presented at the 50th annual meeting of the Child Neurology Society.

Dr. DiSabella and colleagues launched the survey to understand what headache patients were experiencing during the pandemic. They expected that “things were going to go really terrible in terms of headaches – or things would go great, and then things would crash when we had to reintegrate into society,” he said in an interview.

The team surveyed 113 pediatric patients who were evaluated at the hospital’s headache clinic between summer 2020 and winter 2021. Most of the patients were female (60%) and were aged 12-17 years (63%). Twenty-one percent were younger than 12 and 16% were older than 17. Chronic migraine (37%) was the most common diagnosis, followed by migraine with aura (22%), migraine without aura (19%), and new daily persistent headache (15%).

Nearly half (46%) of patients said their headaches had worsened during the pandemic. Many also reported more anxiety (55%), worsened mood (48%) and more stress (55%).

Dr. DiSabella said it’s especially notable that nearly two-thirds of those surveyed reported they were exercising less during the pandemic. Research has suggested that exercise and proper diet/sleep are crucial to improving headaches in kids, he said, and the survey findings suggest that exercise may be especially important. “Engaging in physical activity changes their pain threshold,” he said.

The researchers also reported that 60% of those surveyed said they looked at screens more than 6 hours per day. According to Dr. DiSabella, high screen use may not be worrisome from a headache perspective. “We have another study in publication that shows there’s not a clear association between frequency of screen use and headache intensity,” he said.

The survey doesn’t examine what has happened in recent weeks as schools have reopened. Anecdotally, Dr. DiSabella said some patients with migraine are feeling the stress of returning to normal routines. “They tend to be type A perfectionists and do well when they’re in control of their environment,” he said. “Now they’ve lost the control they had at home and are being put back into a stressful environment.”
 

Pandemic effects mixed

Commenting on the study, child neurologist Andrew D. Hershey, MD, PhD, of Cincinnati Children’s Hospital Medical Center, questioned the finding that many children suffered from more headaches during the pandemic. In his experience, “headaches were overall better when [children] were doing virtual learning,” he said in an interview. “We had fewer admissions, ED visits declined, and patients were maintaining better healthy habits. Some did express anxiety about not seeing friends, but were accommodating by doing this remotely.”

He added: “Since their return, kids are back to the same sleep deprivation issue since schools start too early, and they have more difficulty treating headaches acutely since they have to go to the nurse’s office [to do so]. They self-report a higher degree of stress and anxiety.”

On the other hand, Jack Gladstein, MD, a child neurologist at the University of Maryland, Baltimore, said in an interview that most of his patients suffered more headaches during the pandemic, although a small number with social anxiety thrived because they got to stay at home.

He agreed with Dr. DiSabella about the value of exercise. “At every visit we remind our youngsters with migraine to eat breakfast, exercise, get regular sleep, and drink fluids,” he said.

No study funding was reported. The study authors, Dr. Hershey, and Dr. Gladstein reported no disclosures.

The proportion of children caught up on vaccinations is lower than 2019 levels, despite an increase in weekly vaccine administration among children from summer to fall 2020.

The finding, published in JAMA Pediatrics, joins a growing collection of studies examining the COVID-19 pandemic’s effect on routine pediatric vaccine delivery. A 2021 survey from the Urban Institute that found that nearly one in five parents delayed or did not get care for their children in the past 12 months because of fear of exposure to the virus.

“We need to think about what additional interventions are needed to promote catch-up vaccination, especially for those at-risk populations that we saw were undervaccinated even prior to the pandemic,” study author Malini B. DeSilva, MD, MPH, said in an interview. “[That means] working creatively to ensure that all children would have the opportunity to receive these recommended vaccines.”

While examining data on pediatric vaccination of 1.4 million children between Jan. 5, 2020, and Oct. 3, 2020, across eight health systems in California, Oregon, Washington, Colorado, Minnesota, and Wisconsin, Dr. DeSilva and colleagues saw vaccination administration rates return to near prepandemic levels after an initial decline, particularly after the Centers for Disease Control and Prevention and American Academy of Pediatrics guidelines specified that in-person visits for children younger than 2 years should be prioritized.

“I think we’ve all been concerned and aware that people just weren’t bringing their children to their pediatricians as frequently [caused by] the fear of being in medical settings during the heat of the pandemic,” said James Schneider, MD, who was not involved with the study. “So it’s not surprising that we saw lower rates of overall vaccinations in all age groups.”

The current study found that lower vaccination rates persisted among most age groups from March to September 2020. However, during the period of expanded primary care, which took place between May and October 2020, vaccination administration rates in infants younger than 2 years old and children aged 4-6 years approached or were equal to 2019 rates. However, these rebounds were not enough to make up for the missed vaccines.

Still, only 74% of infants reaching 7 months old in September 2020 were caught up on their vaccinations, compared with 81% of infants turning the same age in 2019. Researchers also found that, compared with 61% of infants reaching 18 months in September 2019, only 57% of 18-month-olds were up to date with vaccinations in September 2020. However, the proportion of 6-, 13-, and 18-year-olds up to date on vaccinations were about the same in 2020 and 2019.

Racial disparities also persisted during this time, with Black children having the lowest proportion of up-to-date vaccinations for most ages from January to September 2020. Although these disparities were evident prior to the pandemic, these differences became more pronounced for the 18-month-old age group, where just 41% of Black infants were up to date in vaccinations, compared with 76% of Asian infants, 54% of Hispanics infants, and 56% of White infants.

Dr. Schneider believes Dr. DeSilva’s study is a “robust” one and paints an accurate picture of the pandemic’s effect on pediatric vaccinations, despite examining data from just eight health systems.

“I think it’s a fairly reasonable representation of what we already have been recognizing during the pandemic,” he explained. “Which is that people are really reluctant to go to their physicians’ offices for routine care because of the fear of getting sick. I think the study emphasized the importance of catching these children up to keep them safe in the future.”

The Advisory Committee on Immunization Practices recommends a childhood immunization schedule that protects children against 14 infectious diseases before their second birthday. Since the on-time administration of these vaccines is essential for preventing communicable diseases, many pediatric offices are trying to ensure a safe environment for patients and families, said Dr. Schneider, chief of pediatric critical care at Cohen Children’s Medical Center, New York.

There’s also some concern that COVID-19 vaccine hesitancy my spillover into routine childhood vaccinations, especially for families who were already hesitant toward the routine well-established vaccine schedule for children.

The CDC and AAP recommend that children continue to receive recommended vaccinations during the COVID-19 pandemic.

To boost the number of children caught up on vaccinations, health system and community-level interventions are needed, especially in underserved communities, the researchers wrote. Additionally, enforcing mandates that require vaccination prior to school entry could also increase vaccine administration across populations and reduce disparities.

The study emphasizes the “immediate and lagging” disruptions in the delivery of pediatric health care caused by the pandemic, which will likely have long-term consequences for pediatric health, Brian P. Jenssen, MD, MSHP, who was not involved in the study, wrote in a solicited commentary.

However, interventions tailored to specific age groups could help remedy this. These include increasing the frequency of well-child care during the next year of life for infants younger than 24 months and prioritizing visits with 13-year-old adolescents who are behind on vaccinations.

“Although there is no evidence base for this approach, such a change could create not only catch-up opportunities for vaccination for children delayed at age 7 and 18 months, but also provide opportunities to attend to developmental concerns and social needs that have emerged during COVID-19,” wrote Dr. Jenssen, a researcher and primary care pediatrician at Children’s Hospital of Philadelphia.

Other practices such as reaching out to patients and families directly via text message, email, or phone to “notify them of needed vaccinations,” vaccine mandates, and having pediatric health systems partner with alternative settings to promote vaccination could also get kids back on track, health wise. Furthermore, financial incentives from insurers or primary care practices also may help.

“The COVID-19 pandemic’s lost care may have long-term consequences unless pediatric health care systems and child health advocates are proactive in engaging families to take advantage of every opportunity to catch up,” Dr. Jenssen wrote.

The proportion of children caught up on vaccinations is lower than 2019 levels, despite an increase in weekly vaccine administration among children from summer to fall 2020.

DeSilva, MD, MPH, said in an interview. “[That means] working creatively to ensure that all children would have the opportunity to receive these recommended vaccines.”

While examining data on pediatric vaccination of 1.4 million children between Jan. 5, 2020, and Oct. 3, 2020, across eight health systems in California, Oregon, Washington, Colorado, Minnesota, and Wisconsin, Dr. DeSilva and colleagues saw vaccination administration rates return to near prepandemic levels after an initial decline, particularly after the Centers for Disease Control and Prevention and American Academy of Pediatrics guidelines specified that in-person visits for children younger than 2 years should be prioritized.

“I think we’ve all been concerned and aware that people just weren’t bringing their children to their pediatricians as frequently [caused by] the fear of being in medical settings during the heat of the pandemic,” said James Schneider, MD, who was not involved with the study. “So it’s not surprising that we saw lower rates of overall vaccinations in all age groups.”

The current study found that lower vaccination rates persisted among most age groups from March to September 2020. However, during the period of expanded primary care, which took place between May and October 2020, vaccination administration rates in infants younger than 2 years old and children aged 4-6 years approached or were equal to 2019 rates. However, these rebounds were not enough to make up for the missed vaccines.

Still, only 74% of infants reaching 7 months old in September 2020 were caught up on their vaccinations, compared with 81% of infants turning the same age in 2019. Researchers also found that, compared with 61% of infants reaching 18 months in September 2019, only 57% of 18-month-olds were up to date with vaccinations in September 2020. However, the proportion of 6-, 13-, and 18-year-olds up to date on vaccinations were about the same in 2020 and 2019.

Racial disparities also persisted during this time, with Black children having the lowest proportion of up-to-date vaccinations for most ages from January to September 2020. Although these disparities were evident prior to the pandemic, these differences became more pronounced for the 18-month-old age group, where just 41% of Black infants were up to date in vaccinations, compared with 76% of Asian infants, 54% of Hispanics infants, and 56% of White infants.

Dr. Schneider believes Dr. DeSilva’s study is a “robust” one and paints an accurate picture of the pandemic’s effect on pediatric vaccinations, despite examining data from just eight health systems.

“I think it’s a fairly reasonable representation of what we already have been recognizing during the pandemic,” he explained. “Which is that people are really reluctant to go to their physicians’ offices for routine care because of the fear of getting sick. I think the study emphasized the importance of catching these children up to keep them safe in the future.”

The Advisory Committee on Immunization Practices recommends a childhood immunization schedule that protects children against 14 infectious diseases before their second birthday. Since the on-time administration of these vaccines is essential for preventing communicable diseases, many pediatric offices are trying to ensure a safe environment for patients and families, said Dr. Schneider, chief of pediatric critical care at Cohen Children’s Medical Center, New York.

There’s also some concern that COVID-19 vaccine hesitancy my spillover into routine childhood vaccinations, especially for families who were already hesitant toward the routine well-established vaccine schedule for children.

The CDC and AAP recommend that children continue to receive recommended vaccinations during the COVID-19 pandemic.

To boost the number of children caught up on vaccinations, health system and community-level interventions are needed, especially in underserved communities, the researchers wrote. Additionally, enforcing mandates that require vaccination prior to school entry could also increase vaccine administration across populations and reduce disparities.

The study emphasizes the “immediate and lagging” disruptions in the delivery of pediatric health care caused by the pandemic, which will likely have long-term consequences for pediatric health, Brian P. Jenssen, MD, MSHP, who was not involved in the study, wrote in a solicited commentary.

However, interventions tailored to specific age groups could help remedy this. These include increasing the frequency of well-child care during the next year of life for infants younger than 24 months and prioritizing visits with 13-year-old adolescents who are behind on vaccinations.

“Although there is no evidence base for this approach, such a change could create not only catch-up opportunities for vaccination for children delayed at age 7 and 18 months, but also provide opportunities to attend to developmental concerns and social needs that have emerged during COVID-19,” wrote Dr. Jenssen, a researcher and primary care pediatrician at Children’s Hospital of Philadelphia.

Other practices such as reaching out to patients and families directly via text message, email, or phone to “notify them of needed vaccinations,” vaccine mandates, and having pediatric health systems partner with alternative settings to promote vaccination could also get kids back on track, health wise. Furthermore, financial incentives from insurers or primary care practices also may help.

“The COVID-19 pandemic’s lost care may have long-term consequences unless pediatric health care systems and child health advocates are proactive in engaging families to take advantage of every opportunity to catch up,” Dr. Jenssen wrote.

The proportion of children caught up on vaccinations is lower than 2019 levels, despite an increase in weekly vaccine administration among children from summer to fall 2020.

The finding, published in JAMA Pediatrics, joins a growing collection of studies examining the COVID-19 pandemic’s effect on routine pediatric vaccine delivery.

A panel of experts that advises the Food and Drug Administration on vaccine decisions voted unanimously Oct. 14 to approve booster doses of Moderna’s COVID-19 vaccine.

The 19 members of the FDA’s Vaccines and Related Biological Products Advisory Committee voted to authorize a 50-milligram dose -- half the dose used in the primary series of shots -- to boost immunity against COVID-19 at least 6 months after the second dose. Those who might need a booster are the same groups who’ve gotten a green light for third Pfizer doses. They include people:

• Over age 65
• Ages 18 to 64 who are at higher risk for severe COVID
• Who are at higher risk of catching COVID because they live in group settings like nursing homes or prisons, or because they are frequently exposed at work, as health care workers are

The agency is not bound by the committee’s vote but usually follows its recommendations.

Some members of the committee said they weren’t satisfied with the data Moderna submitted to support its application but, for practical reasons, said it wouldn’t be fair to take booster doses off the table for Moderna recipients when Pfizer’s boosters were already available.

“The data are not perfect, but these are extraordinary times and we have to work with data that are not perfect,” said Eric Rubin, MD, editor-in-chief of TheNew England Journal of Medicine and a temporary voting member on the committee.

Patrick Moore, MD, a professor at the University of Pittsburgh Cancer Institute who is also a temporary voting member, said he voted to approve the Moderna boosters based “more on a gut feeling than on truly serious data.”

“I’ve got some real issues with this vote,” he said.

“We need to see good solid data, and it needs to be explained well,” Dr. Moore said, challenging companies making future applications to do better.

Next, the FDA will have to formally sign off on the emergency use authorization, which it is expected to do. Then, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will meet to make formal recommendations on use of the Moderna boosters. That group is scheduled to meet Oct. 21 to take up questions of exactly how these boosters should be used.

Peter Marks, MD, head of the FDA’s Center for Biologics Evaluation and Research, cautioned that the CDC is more constrained in making recommendations under an emergency use authorization than it would be if the boosters had gotten full approval. So it will likely align its vote with the conditions of the emergency use authorization from the FDA.

After the advisory committee votes, the director of the CDC has to approve its recommendation.

Overall, data show that two doses of the Moderna vaccine remains highly effective at preventing hospitalization and death. But over time, levels of the body’s first line of defense against a virus -- its neutralizing antibodies -- fall somewhat. This drop seems to correspond with an increased risk for breakthrough cases of COVID-19.

Data presented by Moderna Oct. 14 showed the risk of breakthrough infections increased by 36% in study participants who received the vaccine in their clinical trials, compared to people in the same study who received a placebo first, and got the vaccine later, when the trial was unblended. Their protection was more recent, and they had fewer breakthrough infections.

In considering booster doses, the FDA has asked drugmakers to do studies that look at the immune responses of small groups of study participants and compare them to the immune responses seen in study participants after their first two vaccine doses.

To be considered effective, boosters have to clear two bars. The first looks at the concentration of antibodies generated in the blood of boosted study volunteers. The second looks at how many boosted study participants saw a four-fold increase in their blood antibody levels a month after the booster minus the number of people who saw the same increase after their original two doses.

Moderna presented data that its boosters met the first criteria, but failed to meet the second, perhaps because so many people in the study had good responses after their first two doses of the vaccines.

The FDA’s advisory committee will reconvene Oct. 15 to hear evidence supporting the emergency use authorization of a booster dose of the Johnson & Johnson vaccine.
