– A quarter of urgent contacts in 20 children with generalized severe recessive dystrophic epidermolysis bullosa (GS-RDEB) were tied to esophageal narrowing, according data from a 12-month review of electronic health records.

Urgent advice was sought 102 times outside of regular or scheduled appointments by the parents of 20 children with GS-RDEB, Christine Prodinger, MD, of the University Clinic of Dermatology at Paracelsus Medical University, Salzburg, Austria, and colleagues reported in a poster presentation at the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA). The researchers looked at the records from the EB clinic at Great Ormond Street Hospital for Children NHS Foundation Trust, London, during April 2018–April 2019.

The mean number of urgent contacts with the specialist unit was 5.1 per patient per year, the researchers reported, with 24 of the 102 contacts (23.5%) resulting in the child being admitted to a hospital. Most of the contacts were made via email or telephone to EB nurses (94%), by contacts during home visits (3%), or in an appointment with the palliative or symptom care team (3%).

“The most common reason [for the urgent contact] was acute dysphagia,” which was experienced as choking, throat pain, difficulty eating, reflux, and vomiting, the researchers observed. Dysphagia affected children in 27 of the contacts (26.5%), and resulted in esophageal dilatation in 90% of the cases. Other reasons for urgent contact were skin infection (15.7% of contacts), uncontrolled pain (15.7% of the contacts), and eye problems (11.8%).
 

Esophageal dilatation

Strictures are just one of the esophageal manifestations of the disease, noted Anna Bruckner, MD, associate professor of dermatology and pediatrics in the department of dermatology at the University of Colorado at Denver, Aurora, during an oral presentation. Other possible manifestations include blisters and erosions, the formation of webs – a thin extension of esophageal tissue, perforations, and rupture. “These are primarily problems with dystrophic EB” but can occur with other EB subtypes, she noted.

“We don’t have great evidence” on whether the onset of esophageal strictures can be delayed or prevented, Dr. Bruckner observed. As for management, “fluoroscopy-guided balloon dilatation is probably best” for most patients, but the best procedural approach needs to be discussed on a patient-by-patient basis.

Citing a paper that documents her own experience on the use of esophageal dilatation in 24 children who underwent 231 fluoroscopy-guided balloon dilatation procedures, Dr. Bruckner noted that strictures were most commonly located in the proximal part of the esophagus, with a median distance of 13 cm down from the lips (J Pediatr Gastroenterol Nutr. 2018;67[6]:701-5).

The retrospective chart review reported by Dr. Bruckner showed that there were a median of seven dilatation procedures per patient, and 20 patients had repeated procedures at a median interval of 164 days. About 10% of procedures resulted in adverse events – mostly vomiting, pain, and fever – but there were no perforations or other serious effects, and the rate of subsequent hospitalization was 6.9%.
 

Dysphagia

Dysphagia was the predominant symptom caused by esophageal stricture in another dataset reported in a poster by Elena Pope, MD, MSc, of the Hospital for Sick Children at the University of Toronto, and colleagues.

Of 125 EB patients who had experienced at least 1 esophageal stricture episode, 497 esophageal stricture events were reported, and 85.5% of patients had difficulty swallowing at presentation, with 29.8% unable to swallow solids and 7.2% unable to swallow liquids. Other symptoms at presentation were painful swallowing (11%), food being stuck in the esophagus (8%), regurgitation (5%), coughing (4.8%), and dyspepsia (2.8%).

The aim of the retrospective, multicenter cohort study was to determine the prevalence of, and predisposing factors for, restenosis of esophageal strictures and factors that may predispose to restenosis. The study population consisted of 66 men and 59 women who had experienced their esophageal stricture at around ages 12-13 years. The majority (98.4%) had dystrophic EB, of which almost half (46.5%) had GS-RDEB.

The researchers found that the location of the esophageal stricture was important for restenosis, and that strictures occurring in the lower esophagus were 67.5% less likely to result in restenosis than if they occurred in the upper esophagus (P = .057; hazard ratio, 0.675).

A higher number of strictures was associated with a higher rate of restenosis, they reported. Indeed, patients who had two esophageal strictures had a 29.4% increased risk of restenosis, compared with those who had just one stricture (P = .038; HR, 1.294), and those with three or more strictures had an increased risk of 78.5%, compared with those having one stricture (P = .005; HR, 1.785).

Strictures longer than 1 cm also were associated with a greater (34.7%) risk of restenosis, compared with shorter strictures (P = .032; HR, 1.347). Various methods of resolving the stricture were used, from fluoroscopy-guided balloon dilatation to retro- or antegrade endoscopy. “Irrespective of method, dilatations are successful,” Dr. Pope and colleagues reported. The overall success of dilatation was 99.3%, with full dilatation achieved in almost all of the patients (96%). Of note is that there was a low risk (2.6%) of complications, they observed.

Medications were used in 46.8% of the patients, with the most popular choice being corticosteroids (90.3%), but the researchers noted that the “potential benefit of periprocedural corticosteroids use in decreasing the risk of restenosis needs further exploration.”

Dr. Bruckner had noted in her presentation that her group did not favor the use of periprocedural corticosteroids, but that antifibrotic therapy “could be attractive” for preventing future strictures.

Dr. Prodinger, Dr. Pope, and their colleagues did not provide disclosure information. Dr. Bruckner is the principal investigator for the Epidermolysis Bullosa Clinical Characterization and Outcomes Database. She disclosed the receipt of grants or research funding, honoraria, or consultation fees from a number of drug companies, as well as other support from the EB Research Partnership and the EB Medical Research Foundation.

Meta-analysis highlights safety concerns with interleukin inhibition

– The use of interleukin inhibitors for treatment of rheumatologic diseases doubles a patient’s risk of serious infections, according to a comprehensive systematic review and meta-analysis of 74 randomized, placebo-controlled trials presented by Jawad Bilal, MBBS, at the 2020 Rheumatology Winter Clinical Symposium.

Bruce Jancin/MDedge News
Dr. Jawad Bilal

The meta-analysis, which incorporated 29,214 patients with a variety of rheumatic diseases, demonstrated that patients receiving interleukin (IL) inhibitors had a 1.97-fold increased risk of serious infections, a finding accompanied by a high degree of statistical certainty. The number-needed-to-harm was 67 patients treated for a median of 24 weeks in order to generate one additional serious infection.

“That number-needed-to-harm is a significant finding because having a serious infection means by definition you’re getting admitted to the hospital and receiving IV antibiotics,” Dr. Bilal observed in an interview.

The meta-analysis also found that IL inhibition was associated with a 2.35-fold increased risk of opportunistic infections and a 1.52-fold higher risk of developing cancer, both findings with statistical significance (P =.03) but only moderate certainty because fewer of those events were captured in the trials compared to the numbers of serious infections, explained Dr. Bilal of the University of Arizona, Tucson.

For opportunistic infections, the number-needed-to-harm was 250 patients treated with an IL inhibitor for a median of 54 weeks in order to result in one additional opportunistic infection. For cancer, the number-needed-to-harm was 250 for a median of 24 weeks.

Dr. Bilal noted that while the IL inhibitors are drugs of established efficacy in rheumatologic diseases, their safety has not previously undergone anything approaching the comprehensive scrutiny carried out in this meta-analysis. The meta-analysis, which included all published placebo-controlled randomized trials and their extension studies, employed rigorous methodology in accord with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) statement and the GRADE approach to data analysis. Studies of IL inhibitors in patients with dermatologic and GI diseases were excluded from the meta-analysis.

He offered a caveat regarding the cancer risk findings: “Our analysis showed that the cancer risk is increased, but the results are not conclusive because we only had a few years of data. With cancer, you really need at least 8-10 years of data. So the real-world experience with the interleukin inhibitors in the large registries is what’s going to tell if the cancer risk is really increased or not. In the meantime, we all have to be cautious.”

The number of serious infections collected in the meta-analysis afforded sufficient statistical power for the investigators to break down differential risks based on individual drugs and indications. Among the drugs associated with significantly increased risk of serious infections were anakinra, with an odds ratio of 2.67, compared with placebo; secukinumab with an OR of 2.43; and tocilizumab with an OR or 1.76. Ustekinumab and ixekizumab were associated with 2.57- and 3.89-fold increased risks, respectively, but the number of rheumatology patients treated with those two biologics wasn’t large enough for those findings to achieve statistical significance.

Rheumatoid arthritis patients who received an IL inhibitor rather than placebo had a 1.98-fold increased risk of serious infection, while those with psoriatic arthritis had a 2.21-fold increased risk. Patients treated for SLE had a 6.44-fold increased risk, and those with juvenile idiopathic arthritis had a 5.37-fold higher risk, but the margins for error were such that those results weren’t statistically significant.

“I think this study is going to help clinicians and patients when they’re trying to weigh the risks and benefits of IL inhibitors, especially if they already have risk factors, like a recent history of serious infection or a history of cancer or of opportunistic infection,” Dr. Bilal commented.

A study limitation was that he and his coinvestigators had to lump together the various IL inhibitors in order to gain statistical power, even though the drugs work differently, he noted.

Dr. Bilal reported having no financial conflicts regarding his study, the full details of which have been published (JAMA Netw Open. 2019 Oct 2. doi: 10.1001/jamanetworkopen.2019.13102).

A variety of toys and other play products can cause contact dermatitis in children because of the nature of their ingredients, according to the results of a review of 25 published articles.

“In recent years the products have become a reflection of the compounds used frequently in manufacturing, including metals and plastic compounds,” wrote Justine Fenner, MD, and coauthors, from the departments of dermatology and pediatrics at the Icahn School of Medicine at Mount Sinai, New York,

In a study published in Contact Dermatitis, the researchers identified 25 articles describing dermatitis, rash, or eczema associated with a range of toy and play product terms including Nintendo, PlayStation, putty, glue, doll, game, car, bicycle, slime, iPad, and iPhone.

Overall, nickel was the most common allergen. Cases of nickel dermatitis were associated with laptops, videogame controllers, iPads, and cell phones. Cell phones were the most common electronics associated with contact dermatitis, which was observed on the cheek, periauricular area, and hand, as well as the breast in one case of a patient who kept her phone in her bra.

Other sources of metal allergens were identified in toy cars and costume jewelry, the researchers noted.

In addition, temporary tattoos have been associated with contact dermatitis in children, as have homemade “slime” products, which often contain not only borax or other household detergents, but also glue, shaving cream, or coloring.

However, identification of true allergic contact dermatitis from toys “requires both identification of the chemical contents of toys, which are proprietary in nature, and then epicutaneous allergy testing of these ingredients,” the researchers said.

The study findings were limited by several factors including the consideration only of English-language articles and of cases in children, which thus eliminates other potential cases, the researchers noted. However, the results suggest that dermatologists consider toys as a source of contact dermatitis in children, especially if the time to diagnosis is months to years, they said. “Additionally, it may be useful, as it was in several of the above cases, to have the patient bring in his or her favorite toys for the dermatologist to examine and help further understand the etiology of patient’s rash,” they noted. Moreover, “there is an unmet need for corporations to reveal the chemical ingredients of their toys when allergic contact dermatitis is suspected in order to properly evaluate the patient,” they added.



“Contact dermatitis has been underreported in children and constitutes an ongoing concern,” senior author Nanette Silverberg, MD, chief of pediatric dermatology for the Mount Sinai Health System, said in an interview.

“In particular, toy-related allergy is concerning due to the rise in allergen inclusion in common play items,” she commented. The current analysis identified many case reports of allergens that pediatric dermatologists are frequently seeing in their offices, notably metals such as nickel, she pointed out. “The allergen that always stands out ahead of others is nickel,” Dr. Silverberg said. “Nickel allergy affects about 25% of Americans, often starting in early childhood,” she said. “In the European Union, legislation has been passed to reduce nickel release from metals, which has resulted in less sensitization to nickel. We lack such legislation in the United States,” she added. 

Other trending allergens include methylchloroisothiazolinone/methylisothiazolinone, which may be components of glue or other ingredients in some “slime” products, Dr. Silverberg said.

She advised clinicians to consider patch testing when addressing localized or persistent dermatitis in children. “Furthermore, consider toys as potential relevant allergens that should be modified in order to achieve skin improvement,” she said.

“Greater reporting of pediatric allergic contact dermatitis is needed,” Dr. Silverberg emphasized. “Additionally, surveillance and monitoring for trends in allergen exposures in toys and personal care items is required to analyze this ongoing concern of childhood,” she said.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Antibiotic resistance rises among pneumococcus strains in kids

What are the implications for treatment

Antibiotic resistance in strains of Streptococcus pneumoniae has been rising since 2013 because of changing susceptibility profiles, based on data from 1,201 isolates collected from 448 children in primary care settings.

“New strains expressing capsular serotypes not included in the 13-valent pneumococcal conjugate vaccine are emerging to cause disease, and strains that acquire antibiotic resistance are increasing in frequency due to their survival of the fittest advantage,” wrote Ravinder Kaur, PhD, of Rochester (N.Y.) General Hospital Research Institute, and colleagues.

Similar Darwinian principles occurred after the introduction of PCV-7, the study authors added.

In a prospective cohort study published in Clinical Infectious Diseases, the researchers reviewed 1,201 isolates collected from the nasopharynx during healthy periods, and from the nasopharynx and middle ear fluid (MEF) during episodes of acute otitis media, in children aged 6-36 months who were seen in primary care settings.

The isolates were collected during 2006-2016 to reflect the pre- and post-PCV13 era. Children received PCV-7 from 2006 until April 2010, and received PCV-13 after April 2010.

Overall, the number of acute otitis media (AOM) cases caused by S. pneumoniae was not significantly different between the PCV-7 and PCV-13 eras, nor was the frequency of pneumococci identified in the nasopharynx during healthy visits and visits at the start of an AOM infection.

The researchers examined susceptibility using minimum inhibitory concentrations (MIC). During healthy visits, the MIC50 of isolated pneumococci was low (no greater than 0.06 mcg/mL) for all four beta-lactam drugs tested. And it didn’t change significantly over the study years.

In contrast, among the nasopharyngeal and MEF isolates during AOM, the MIC50 to penicillin, amoxicillin, ceftriaxone, and meropenem during 2013-2016 rose significantly, the investigators said.

A change in antibiotic susceptibility within a subtype also contributed to the development of PCV-13 resistance.

The study authors identified three serotypes that affected the changes in susceptibility in their study population. Serotypes 35B and 35F increased their beta-lactam resistance during 2013-2016, and serotype 11A had a higher MIC to quinolones and became more prevalent during 2013-2016. Those three serotypes accounted for most of the change in antibiotic susceptibility, the researchers said.

In addition, “the frequency of strains resistant to penicillin and amoxicillin decreased with the introduction of PCV-13, but rebounded to levels similar to those before PCV-13 introduction by 2015-2016,” the investigators noted.

The study findings were limited by several factors, including the homogeneous study population and potential lack of generalizability to other settings. In addition, the researchers did not study antibiotic consumption or antibiotic treatment failure, and they could not account for potential AOM cases that may have been treated in settings other than primary care.

However, the investigators said the results support the need for additional studies and attention to the development of the next generation of PCVs, the PCV-15 and PCV-20. Both include serotypes 22F and 33F, but neither includes 35B or 35F. The PCV-20 also includes 11A and 15B.

The study was supported in part by the National Institutes of Health and Sanofi Pasteur. Some isolates collected during the 2010-2013 time period were part of a study supported by Pfizer. The researchers had no relevant financial conflicts to disclose.

Body

Dr. Kaur and colleagues report their analysis of pneumococcal resistance among nasopharyngeal and middle ear isolates (90% nasopharyngeal and 10% middle ear) collected between 2008 and 2016. They demonstrate the dominant role that nonvaccine serotypes play in carriage and acute otitis media (AOM) in children, and by extension potentially the entire spectrum of pneumococcal disease in the 13-valent pneumococcal conjugate vaccine (PCV13) era. Nonsusceptibility to beta-lactams was reported for one-third of isolates with the increase in the most recent reported years (2013-2016).
 
What are the implications for treatment of pneumococcal infections? For AOM, amoxicillin minimum inhibitory concentrations (MIC) were all less than 4 mcg/mL, which is the pharmacodynamic breakpoint for high-dose (90 mg/kg per day) AOM regimens; these data support continued use of high-dose amoxicillin for children with AOM that requires antimicrobial treatment. Resistance to macrolides (erythromycin and likely azithromycin) occurred in approximately one-third of isolates; however, in contrast to beta-lactams (amoxicillin), higher macrolide doses do not overcome resistance. Thus macrolide use for AOM appears limited to those with beta-lactam allergy and no better alternative drug, i.e., expect failure in one-third of AOM patients if macrolides are used. For ceftriaxone, no 2013-2016 isolate had a MIC over 0.5 mcg/mL, implying that ceftriaxone remains appropriate first-line therapy for serious pneumococcal disease and effective for pneumococcal AOM when oral drugs have failed or are not an option because of repeated emesis. Interestingly, trimethoprim/sulfamethoxazole (T/S) had lower resistance rates against the nonvaccine “bad boy” serogroup 35 (8%-15%), compared with cephalosporins (32%-57%). Perhaps we are back to the future and T/S will again have a role against pneumococcal AOM. Of note, no isolate was resistant to levofloxacin or linezolid. Linezolid or macrolide use alone must be considered with the caveat that nontypeable Haemophilus influenzae now likely surpasses pneumococcus as an AOM pathogen, and neither drug class is active against nontypeable H. influenzae.
 
What are the implications for prevention? This is one of many studies in the post-PCV era reporting serotype replacement with nonvaccine serotypes. But most prior studies reported reduced overall disease burden; in other words, the absolute number of pneumococcal infections was reduced, but residual AOM nonvaccine types dominated as the etiology. The current study, however, suggests that the overall number of AOM episodes may not be less because increases in AOM caused by nonvaccine serotypes may be offsetting declines in AOM caused by vaccine serotypes. This concept contrasts to multiple large epidemiologic studies demonstrating a decline in overall incidence of AOM office visits/episodes and several Israeli studies reporting a decline in pneumococcal AOM in children who warrant tympanocentesis. These new data are food for thought, but antibiotic resistance can vary regionally, so confirmation based on data from other regions seems warranted.
  
Next-generation vaccines will need to consider which serotypes are prevalent in pneumococcal disease, including AOM, as we continue into the PCV13 era. However, serotypes causing invasive pneumococcal disease and pneumonia would be higher priorities than AOM. Indeed, several candidate PCV vaccines are currently in clinical trials adding up to seven serotypes, including most of the newly emerging invasive disease serotypes. One downside to the newer PCVs is lack of serogroup 35, a prominent culprit in AOM resistance in the current report.

In contrast, among the nasopharyngeal and MEF isolates during AOM, the MIC50 to penicillin, amoxicillin, ceftriaxone, and meropenem during 2013-2016 rose significantly, the investigators said.

A change in antibiotic susceptibility within a subtype also contributed to the development of PCV-13 resistance.

The study authors identified three serotypes that affected the changes in susceptibility in their study population. Serotypes 35B and 35F increased their beta-lactam resistance during 2013-2016, and serotype 11A had a higher MIC to quinolones and became more prevalent during 2013-2016. Those three serotypes accounted for most of the change in antibiotic susceptibility, the researchers said.

In addition, “the frequency of strains resistant to penicillin and amoxicillin decreased with the introduction of PCV-13, but rebounded to levels similar to those before PCV-13 introduction by 2015-2016,” the investigators noted.

The study findings were limited by several factors, including the homogeneous study population and potential lack of generalizability to other settings. In addition, the researchers did not study antibiotic consumption or antibiotic treatment failure, and they could not account for potential AOM cases that may have been treated in settings other than primary care.

However, the investigators said the results support the need for additional studies and attention to the development of the next generation of PCVs, the PCV-15 and PCV-20. Both include serotypes 22F and 33F, but neither includes 35B or 35F. The PCV-20 also includes 11A and 15B.

The study was supported in part by the National Institutes of Health and Sanofi Pasteur. Some isolates collected during the 2010-2013 time period were part of a study supported by Pfizer. The researchers had no relevant financial conflicts to disclose.

Children bearing the brunt of declining flu activity

Article Type

Tue, 06/16/2020 - 14:42

National flu activity decreased for the second consecutive week, but pediatric mortality is heading in the opposite direction, according to the Centers for Disease Control and Prevention.

MDedge News

Influenza-like illness (ILI) represented 5.5% of all visits to outpatient health care providers during the week ending Feb. 22, compared with 6.1% the previous week, the CDC’s influenza division reported Feb. 28. The ILI visit rate had reached 6.6% in early February after dropping to 5.0% in mid-January, following a rise to a season-high 7.1% in the last week of December.

Another measure of ILI activity, the percentage of laboratory specimens testing positive, also declined for the second week in a row. The rate was 26.4% for the week ending Feb. 22, which is down from the season high of 30.3% reached 2 weeks before, the influenza division said.



ILI-related deaths among children, however, are not dropping. There were 20 pediatric deaths reported during the week, more than any other single week this season. The total for 2019-2020 is now up to 125, and that “number is higher for the same time period than in every season since reporting began in 2004-05, except for the 2009 pandemic,” the CDC noted.

Hospitalization rates, which have been fairly typical in the general population, also are elevated for young adults and school-aged children, the agency said, and “rates among children 0-4 years old are now the highest CDC has on record at this point in the season, surpassing rates reported during the second wave of the 2009 H1N1 pandemic.”

Key differences found between pediatric- and adult-onset MS

Article Type
Changed
Mon, 03/09/2020 - 10:08

Patients with pediatric-onset multiple sclerosis (POMS) have less higher education and greater use of high-efficacy disease-modifying therapy (DMT), compared with patients with adult-onset MS (AOMS), according to data presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

Dr. Mary Rensel

Among patients with POMS, researchers also have observed an association between fatigue and mood disorders on one hand and DMT choice on the other hand. “These findings confirm the unique features of POMS and suggest that DMT choice in POMS and AOMS may influence the frequency of fatigue and mood disorders,” said Mary Rensel, MD, staff neurologist in neuroimmunology at Cleveland Clinic’s Mellen Center for MS Treatment and Research, and colleagues.

POMS is defined as MS onset before age 18, and the disease characteristics of POMS and AOMS are distinct. The former diagnosis is rare, which has limited the amount of data collected on POMS to date.

MS Partners Advancing Technology and Health Solutions (MS-PATHS), sponsored by Biogen, is a multicenter initiative in which researchers collect MS performance measures longitudinally at each patient visit. MS-PATHS data include sociodemographic information, patient-reported outcomes (PROs), functional outcomes (FOs), MS phenotype, and DMT. Using MS-PATHS data, Dr. Rensel and colleagues sought to determine differences in sociodemographics, MS phenotype, PRO, FO, and DMT among patients with POMS and between patients with POMS and those with AOMS.

The investigators analyzed data cut 9 of the MS-PATHS database for their study. They included 637 participants with POMS and matched them with patients with AOMS, based on disease duration, in a 1:5 ratio. Dr. Rensel and colleagues categorized DMTs as high, mid, or low efficacy. They calculated descriptive statistics to characterize the study population. In addition, they compared MS FOs and PROs in the matched cohort using the Wilcoxon rank-sum test. Finally, linear regression analysis allowed the investigators to identify differences in the data set, while adjusting for important covariates.

The matched cohort included 5,857 patients with AOMS and 600 patients with POMS. The patients with AOMS had an average age of 49.8 years. About 87.5% of these patients were white, and 73.5% were female. The POMS patients had an average age of 31.49 years. Overall, 76.7% of these patients were white, and 73.2% were female. Dr. Rensel and colleagues found significant differences between the two groups in age at encounter, disease duration, race, insurance, Patient Determined Disease Steps (PDDS), education, employment, FOs, PROs, and DMT.

Patients with POMS used high-efficacy DMT more frequently than those with AOMS. The rate of depression was similar between patients with AOMS and those with POMS. Depression, anxiety, and fatigue were associated with DMT potency in AOMS, and anxiety and fatigue were associated with DMT groups in POMS.

Racial differences between POMS and AOMS have been reported previously, said Dr. Rensel. First-generation immigrant children have an increased risk of POMS, compared with other children. “In our data set, we had more Asians, more blacks, and fewer Caucasians in the POMS group,” said Dr. Rensel. People from a socioeconomically challenged environment have an increased risk of POMS, and this observation may explain the difference in insurance coverage between the POMS and AOMS groups, she added. Socioeconomic challenges also may explain the difference in the rate of higher education between the two groups.

“Why were the POMS cases associated with higher-efficacy DMT when only one oral MS DMT is [Food and Drug Administration]-approved for POMS?” Dr. Rensel asked. “This is likely due to the fact that POMS cases tend to have higher disease activity with more relapses and more brain lesions, leading to the choice of higher efficacy DMTs that are currently not FDA-approved for POMS.”

These data “may help [clinicians] caring for kids and teens, especially non-Caucasian [patients], to consider MS on the differential diagnosis,” Dr. Rensel added. “Mood disorders in POMS were as common as mood disorders in AOMS, so these should be screened for in this POMS population.”

Dr. Rensel has received funding for consulting, research, or patient education from Biogen, Genentech, Genzyme, Medimmune, MSAA, NMSS, Novartis, TSerono, and Teva.

Community-wide initiative ups teen LARC adoption sixfold

Wed, 02/26/2020 - 14:19

In Rochester, N.Y., a comprehensive community initiative that raised awareness about and delivered training in the use of long-acting reversible contraceptives (LARCs) significantly upped LARC adoption among sexually active female high schoolers.

Over the course of the 3-year project, LARC use rose from about 4% to 24% in this group, a statistically significant increase (P less than .0001). During the same time period, LARC use increased nationally, as well, but at a lower rate, rising from 2% to 5% for the same population, while New York state saw LARC use rise from 2% to 5%.

In New York City, where an unrelated LARC awareness campaign was conducted, LARC use went from 3% to 5% over the study period for sexually active female high school students. Comparing the trend in LARC use in Rochester to the secular trend in these control groups showed significantly higher uptake over time in Rochester (P less than .0001).

Through a series of lunch-and-learn talks given to adults who work with adolescents in community-based settings and in medical settings, the Greater Rochester LARC Initiative reached more than 1,300 individuals during July 2014-June 2017, C. Andrew Aligne, MD, MPH, of the University of Rochester (N.Y.), and coauthors reported in the American Journal of Obstetrics and Gynecology.

Of the 81 total talks delivered, 50 were in medical settings, reaching 703 attendees ranging from front-office personnel to primary care physicians, advanced practice clinicians, and nurses; the talks in community-based settings reached 662 attendees.

“We use the term ‘community detailing’ to describe the design of the intervention because it was an innovative hybrid of academic detailing and community health education,” explained Dr. Aligne and colleagues. This approach is a unique, feasible, and effective approach to unintended adolescent pregnancy programs. “The community detailing approach could be a useful complement to programs for preventing unintended adolescent pregnancy.”

The study’s primary outcome measure was LARC use among sexually active female high school students as identified by responses on the U.S. Centers for Disease Control and Statistics’ Youth Risk Behavior Survey (YRBS).

YRBS data were examined for the years 2013, 2015, and 2017, spanning the period before and after the LARC initiative was begun. A separate question about LARC use wasn’t included in the 2013 YRBS survey, so the investigators used a generous estimate that two-thirds of respondents who reported using the “other” contraceptive category for that year were using LARCs. That category was chosen by a total of 6% of respondents, and encompassed LARC use along with use of the patch, ring, diaphragm, and fertility awareness, explained Dr. Aligne and collaborators.

Addressing the problem of failure to use a condom with LARC use, Dr. Aligne and collaborators found overall low rates of dual-method use, but higher rates in Rochester than in the comparison groups. In Rochester, 78% of respondents reported that they also did not use condoms. This figure was lower than the 91% reported for the United States as a whole, and also was lower than the 93% reported in New York City and the 85% reported in New York state. No increase in sexually transmitted infections was seen in Rochester’s sexually active high school females during the study period.

“Our main finding of increased LARC use is consistent with the literature demonstrating that many sexually active young women, including adolescents, will choose LARC if they are given access not only to birth control itself, but also to accurate information about various contraceptive methods,” concluded Dr. Aligne and his associates.

A practical strength of the Greater Rochester LARC initiative was that it capitalized on existing resources, such as New York state’s preexisting program for free access to contraception and similar provisions in the Affordable Care Act. Also, local Title X clinics that were enrolled in New York’s free contraception initiative already had practitioners who were trained and able to provide same-day LARC insertion.

Pediatricians engaged in the initiative were able to receive free training from LARC manufacturers, as mandated by the Food and Drug Administration. Through collaboration with implant manufacturers, Rochester LARC Initiative staff were able to piggyback on training sessions to add education about contraception counseling and the importance of offering access to all contraception methods.

Taken as a whole, the LARC Initiative could be scaled up, wrote Dr. Aligne and his coauthors, a potential boon in the 21 states where qualifying individuals younger than 19 years of age are eligible for Medicaid reimbursement for family planning services. “Even though easy LARC access is far from universal, there are vast areas of the nation where cost need not be seen as an insurmountable barrier.” Dr. Aligne and coauthors also addressed the fraught history of reproductive justice in the United States, cautioning that universal LARC adoption was not – and should not be – the goal of such initiatives. “There is a history of reproductive coercion in the U.S. including forced sterilization of women of color; therefore, it is critical that LARC methods not be imposed on any particular group. On the other hand, LARC should not be withheld deliberately from adolescents who want it, as this is another form of injustice,” they wrote. “The goal should be to empower individuals to decide what is right for them in a context of social and reproductive justice.”

Using the nationally administered YRBS was a significant strength of the study, commented Dr. Aligne and his collaborators. “This allowed us to employ the study design of pre-post with a nonrandomized control group,” the investigators noted, adding that the “relatively rigorous” methodology reduced the risk of problems with internal validity, and also allowed comparisons between changes in Rochester and those at the state and national level.

However, the researchers acknowledged that the study was not a randomized trial, and there’s always the possibility of unknown confounders contributing to LARC uptake during the study period. Also, the YRBS is a self-report instrument and only includes those enrolled in school.

Dr. Aligne reported that his spouse received compensation for providing contraceptive implant insertion training, as did two coauthors. The LARC initiative was supported by a grant from the Greater Rochester Health Foundation.

Dr. Aligne reported that his spouse received compensation for providing contraceptive implant insertion training, as did two coauthors. The LARC initiative was supported by a grant from the Greater Rochester Health Foundation.

In Rochester, N.Y., a comprehensive community initiative that raised awareness about and delivered training in the use of long-acting reversible contraceptives (LARCs) significantly upped LARC adoption among sexually active female high schoolers.

Over the course of the 3-year project, LARC use rose from about 4% to 24% in this group, a statistically significant increase (P less than .0001). During the same time period, LARC use increased nationally, as well, but at a lower rate, rising from 2% to 5% for the same population, while New York state saw LARC use rise from 2% to 5%.

In New York City, where an unrelated LARC awareness campaign was conducted, LARC use went from 3% to 5% over the study period for sexually active female high school students. Comparing the trend in LARC use in Rochester to the secular trend in these control groups showed significantly higher uptake over time in Rochester (P less than .0001).

Through a series of lunch-and-learn talks given to adults who work with adolescents in community-based settings and in medical settings, the Greater Rochester LARC Initiative reached more than 1,300 individuals during July 2014-June 2017, C. Andrew Aligne, MD, MPH, of the University of Rochester (N.Y.), and coauthors reported in the American Journal of Obstetrics and Gynecology.

Of the 81 total talks delivered, 50 were in medical settings, reaching 703 attendees ranging from front-office personnel to primary care physicians, advanced practice clinicians, and nurses; the talks in community-based settings reached 662 attendees.

“We use the term ‘community detailing’ to describe the design of the intervention because it was an innovative hybrid of academic detailing and community health education,” explained Dr. Aligne and colleagues. This approach is a unique, feasible, and effective approach to unintended adolescent pregnancy programs. “The community detailing approach could be a useful complement to programs for preventing unintended adolescent pregnancy.”

The study’s primary outcome measure was LARC use among sexually active female high school students as identified by responses on the U.S. Centers for Disease Control and Statistics’ Youth Risk Behavior Survey (YRBS).

YRBS data were examined for the years 2013, 2015, and 2017, spanning the period before and after the LARC initiative was begun. A separate question about LARC use wasn’t included in the 2013 YRBS survey, so the investigators used a generous estimate that two-thirds of respondents who reported using the “other” contraceptive category for that year were using LARCs. That category was chosen by a total of 6% of respondents, and encompassed LARC use along with use of the patch, ring, diaphragm, and fertility awareness, explained Dr. Aligne and collaborators.

Addressing the problem of failure to use a condom with LARC use, Dr. Aligne and collaborators found overall low rates of dual-method use, but higher rates in Rochester than in the comparison groups. In Rochester, 78% of respondents reported that they also did not use condoms. This figure was lower than the 91% reported for the United States as a whole, and also was lower than the 93% reported in New York City and the 85% reported in New York state. No increase in sexually transmitted infections was seen in Rochester’s sexually active high school females during the study period.

“Our main finding of increased LARC use is consistent with the literature demonstrating that many sexually active young women, including adolescents, will choose LARC if they are given access not only to birth control itself, but also to accurate information about various contraceptive methods,” concluded Dr. Aligne and his associates.

A practical strength of the Greater Rochester LARC initiative was that it capitalized on existing resources, such as New York state’s preexisting program for free access to contraception and similar provisions in the Affordable Care Act. Also, local Title X clinics that were enrolled in New York’s free contraception initiative already had practitioners who were trained and able to provide same-day LARC insertion.

Pediatricians engaged in the initiative were able to receive free training from LARC manufacturers, as mandated by the Food and Drug Administration. Through collaboration with implant manufacturers, Rochester LARC Initiative staff were able to piggyback on training sessions to add education about contraception counseling and the importance of offering access to all contraception methods.

Taken as a whole, the LARC Initiative could be scaled up, wrote Dr. Aligne and his coauthors, a potential boon in the 21 states where qualifying individuals younger than 19 years of age are eligible for Medicaid reimbursement for family planning services. “Even though easy LARC access is far from universal, there are vast areas of the nation where cost need not be seen as an insurmountable barrier.” Dr. Aligne and coauthors also addressed the fraught history of reproductive justice in the United States, cautioning that universal LARC adoption was not – and should not be – the goal of such initiatives. “There is a history of reproductive coercion in the U.S. including forced sterilization of women of color; therefore, it is critical that LARC methods not be imposed on any particular group. On the other hand, LARC should not be withheld deliberately from adolescents who want it, as this is another form of injustice,” they wrote. “The goal should be to empower individuals to decide what is right for them in a context of social and reproductive justice.”

Using the nationally administered YRBS was a significant strength of the study, commented Dr. Aligne and his collaborators. “This allowed us to employ the study design of pre-post with a nonrandomized control group,” the investigators noted, adding that the “relatively rigorous” methodology reduced the risk of problems with internal validity, and also allowed comparisons between changes in Rochester and those at the state and national level.

Persistent Chlorotrichosis With Chronic Sun Exposure

 

To the Editor:

Chlorotrichosis, or green hair discoloration, is a dermatologic condition secondary to copper deposition on the hair. It most often is seen among swimmers who have prolonged exposure to chlorinated pools. The classic patient has predisposing chemical, heat, or mechanical damage to the hair shaft and usually lighter-colored hair.1-3 We present a case of chlorotrichosis in a young brunette patient who did not have predisposing factors except for chronic sun exposure.

A 13-year-old healthy adolescent girl with brown hair presented with persistent green hair for 2 years (Figure 1A). She had first noted hair discoloration after swimming in a neighbor’s chlorinated outdoor pool during summertime but experienced year-round persistence even without swimming. She denied any history of typical risk factors for hair damage, including exposure to hair dye or bleach, styling products, heat, or mechanical damage from excessive brushing. Her sister had blonde hair with a history of similar activities and exposures, and although she did style her hair with heat, she did not develop hair discoloration. The patient lived in a newer home, and prior tap water testing did not show elevated levels of copper. She admitted to strictly wearing her hair down at all times, including during strenuous activity and swimming. Excessive teasing at school prompted her mother to seek advice from hair salons. Bleaching test strips of hair reportedly caused paradoxical intensification of green, and the patient declined recommendations for red hair dye. The patient also tried Internet-based suggestions such as topically applying crushed aspirin, lemon juice, tea tree oil, and clarifying shampoos, which all failed to result in notable improvement.

Figure 1. A, Patient with green hair (chlorotrichosis) before treatment. B, Patient’s hair after 2 treatments with penicillamine shampoo.


Physical examination revealed a sun-exposed distribution of ashy green hair that was worse at the distal hair ends and completely spared the roots. Trichoscopy of discolored hair (Figure 2A) revealed diffuse cuticle thinning, whereas unaffected hair appeared normal (Figure 2B). Because the patient reported slight improvement with tea tree oil, treatment was initiated with twice-weekly hot vegetable oil treatments applied for 20 minutes, which ultimately proved unsuccessful. Penicillamine shampoo (250-mg capsule of penicillamine into 5-mL purified water and 5-mL pH-balanced clear shampoo) was then recommended. At 3-month follow-up, the patient exhibited notable improvement of the hair discoloration, with only mild persistence at the distal ends of sun-damaged hair, visible only under fluorescent lighting (Figure 1B). Our recommendations thereafter were focused on prevention (Table).

Figure 2. A, Trichoscopy of chlorotrichosis-affected hair demonstrated diffuse cuticle thinning (original magnification ×4). B, Trichoscopy of unaffected hair showed a thicker healthier cuticle (original magnification ×4).


The source of exogenous copper in chlorotrichosis commonly is tap water flowing through copper pipes or swimming pools rich in chlorine and copper-containing algaecides.2,4,8 The acidity of tap water is thought to cause the release of copper from the pipes.2,5 Such acidity could result from the effects of acid rain on water reservoirs or from water additives such as fluoride2 or those used in decalcification systems.5 Additionally, the attachment of electrical grounds to copper piping can cause copper to solubilize through an electric current, increasing water levels of copper.3 Although low pH facilitates copper solubility, high pH within the hair facilitates copper precipitation, which is quickly followed by adhesion to anionic molecules within hair shafts. Therefore, it is postulated that chlorotrichosis may persist in insufficiently rinsed hair with residual alkaline shampoo.6

Beyond pH flux in the induction of chlorotrichosis, other environmental agents have been suspected to play a role. A case report of green hair in a black patient following use of selenium sulfide 2.5% shampoo identified hair damage from tinea capitis infection as predisposing to chlorotrichosis.9 Other reports have cited tar shampoo and industrial exposure to cobalt, nickel, brass, mercury, or chromium as causative factors.2,3,6,7 Interestingly, green hair discoloration also has been observed in the metabolic disorder phenylketonuria.1



Few individuals exposed to elevated levels of copper will develop chlorotrichosis, which emphasizes the critical role of predisposing hair damage in its pathogenesis. With violation of the hair cuticle, chlorine can crystallize and copper can adhere to the hair shaft.10 Bleaching and waving of the hair also appear to alter the composition of keratin by increasing the number of cysteic acid and similar anionic sulfonate groups, which can bind copper.8

Although not harmful, chlorotrichosis may be aesthetically undesirable and lead to considerable social ostracism. Without intrinsic hair defects or obvious differences in predisposing factors, the question was raised as to why our patient, as a brunette, experienced dramatic hair discoloration while her blonde sister was entirely unaffected. We postulated that our patient’s persistent green hair may have been due to her unique predisposition to extensive sun-induced and mechanical hair damage because of her unwavering tendency to wear her hair down at all times. A variety of treatments of variable reported efficacy have been proposed (Table); fortunately, if treatments fail, the discoloration resolves with hair growth.



This case is unique in that it presented in a brunette patient with seemingly minimal hair damage with an unaffected blonde-haired sibling and with persistence over years. Furthermore, it lends credence to the use of penicillamine shampoo in treating chlorotrichosis, even in particularly difficult cases in which other treatments have failed.

Practice Points

  • Chlorotrichosis is the deposition of copper onto hair, which causes a green discoloration and most commonly occurs in blonde patients with excessive exposure to chlorinated water.
  • Hair cuticle damage from hair care practices, such as use of heat or chemicals, can predispose patients to the development of chlorotrichosis.
  • Although a number of treatments have been proposed, the use of penicillamine shampoo seems to be particularly effective and works via chelation of the adherent copper molecules.

Unilateral Vesicular Eruption in a Neonate

The Diagnosis: Incontinentia Pigmenti 

The patient was diagnosed clinically with the vesicular stage of incontinentia pigmenti (IP), a rare, X-linked dominant neuroectodermal dysplasia that usually is lethal in males. The genetic mutation has been identified in the IKBKG gene (inhibitor of nuclear factor κB; formally NEMO), which leads to a truncated and defective nuclear factor κB. Female infants survive and display characteristic findings on examination due to X-inactivation leading to mosaicism.1 Worldwide, there are approximately 27.6 new cases of IP per year. Although it is heritable, the majority (65%-75%) of cases are due to sporadic mutations, with the remaining minority (25%-35%) representing familial disease.1 

Cutaneous findings of IP classically progress through 4 stages, though individual patients often do not develop the characteristic lesions of each of the 4 stages. The vesicular stage (stage 1) presented in our patient (quiz image). This stage presents within 2 weeks of birth in 90% of patients and typically disappears when the patient is approximately 4 months of age.1-3 Although the clinical presentation is striking, it is essential to rule out herpes simplex virus infection, which can mimic vesicular IP. Localized herpes simplex virus is most commonly seen in clusters on the scalp and often is not present at birth. Alternatively, IP is most often seen on the extremities in bands or whorls of distribution along Blaschko lines,4 as in this patient. 

Stage 2 (the verrucous stage) presents with verrucous papules or pustules in a similar blaschkoid distribution. Areas previously involved in stage 1 are not always the same areas affected in stage 2. Approximately 70% of patients develop stage 2 lesions, usually at 2 to 6 weeks of age.1-3 Erythema toxicum neonatorum presents in the first week of life with pustules often on the trunk or extremities, but these lesions are not confined to Blaschko lines, differentiating it from IP.

The third stage (hyperpigmented stage) lends the disease its name and occurs in 90% to 95% of patients with IP. Linear and whorled hyperpigmentation develops in early infancy and can either persist or fade by adolescence.1 Pustules and hyperpigmentation in transient neonatal pustular melanosis may be similar to this stage of IP, but the distribution is more variable and progression to other lesions is not seen.5 

The fourth and final stage is the hypopigmented stage, whereby blaschkoid linear and whorled lines of hypopigmentation with or without both atrophy and alopecia develop in 75% of patients. This is the last finding, beginning in adolescence and often persisting into adulthood.1 Goltz syndrome is another X-linked dominant disorder with features similar to IP. Verrucous and atrophic lesions along Blaschko lines are reminiscent of the second and fourth stages of IP but are differentiated in Goltz syndrome because they present concurrently rather than in sequential stages such as IP. Similar extracutaneous organs are affected such as the eyes, teeth, and nails; however, Goltz syndrome may be associated with more distinguishing systemic signs such as sweating and skeletal abnormalities.6 

Given its unique appearance, physicians usually diagnose IP clinically after identification of characteristic linear lesions along the lines of Blaschko in an infant or neonate. Skin biopsy is confirmatory, which would differ depending on the stage of disease biopsied. The vesicular stage is characterized by eosinophilic spongiosis and is differentiated from other items on the histologic differential diagnosis by the presence of dyskeratosis.7 Genetic testing is available and should be performed along with a physical examination of the mother for counseling  purposes.1 

Proper diagnosis is critical because of the potential multisystem nature of the disease with implications for longitudinal care and prognosis in patients. As in other neurocutaneous disease, IP can affect the hair, nails, teeth, central nervous system, and eyes. All IP patients receive a referral to ophthalmology at the time of diagnosis for a dilated fundus examination, with repeat examinations every several months initially--every 3 months for a year, every 6 months from 1 to 3 years of age--and annually thereafter. Dental evaluation should occur at 6 months of age or whenever the first tooth erupts.1 Mental retardation, seizures, and developmental delay can occur and usually are evident in the first year of life. Patients should have developmental milestones closely  monitored and be referred to appropriate specialists if signs or symptoms develop consistent with neurologic involvement.1

The Diagnosis: Incontinentia Pigmenti 

The patient was diagnosed clinically with the vesicular stage of incontinentia pigmenti (IP), a rare, X-linked dominant neuroectodermal dysplasia that usually is lethal in males. The genetic mutation has been identified in the IKBKG gene (inhibitor of nuclear factor κB; formally NEMO), which leads to a truncated and defective nuclear factor κB. Female infants survive and display characteristic findings on examination due to X-inactivation leading to mosaicism.1 Worldwide, there are approximately 27.6 new cases of IP per year. Although it is heritable, the majority (65%-75%) of cases are due to sporadic mutations, with the remaining minority (25%-35%) representing familial disease.1 

Cutaneous findings of IP classically progress through 4 stages, though individual patients often do not develop the characteristic lesions of each of the 4 stages. The vesicular stage (stage 1) presented in our patient (quiz image). This stage presents within 2 weeks of birth in 90% of patients and typically disappears when the patient is approximately 4 months of age.1-3 Although the clinical presentation is striking, it is essential to rule out herpes simplex virus infection, which can mimic vesicular IP. Localized herpes simplex virus is most commonly seen in clusters on the scalp and often is not present at birth. Alternatively, IP is most often seen on the extremities in bands or whorls of distribution along Blaschko lines,4 as in this patient. 

Stage 2 (the verrucous stage) presents with verrucous papules or pustules in a similar blaschkoid distribution. Areas previously involved in stage 1 are not always the same areas affected in stage 2. Approximately 70% of patients develop stage 2 lesions, usually at 2 to 6 weeks of age.1-3 Erythema toxicum neonatorum presents in the first week of life with pustules often on the trunk or extremities, but these lesions are not confined to Blaschko lines, differentiating it from IP.

The third stage (hyperpigmented stage) lends the disease its name and occurs in 90% to 95% of patients with IP. Linear and whorled hyperpigmentation develops in early infancy and can either persist or fade by adolescence.1 Pustules and hyperpigmentation in transient neonatal pustular melanosis may be similar to this stage of IP, but the distribution is more variable and progression to other lesions is not seen.5 

The fourth and final stage is the hypopigmented stage, whereby blaschkoid linear and whorled lines of hypopigmentation with or without both atrophy and alopecia develop in 75% of patients. This is the last finding, beginning in adolescence and often persisting into adulthood.1 Goltz syndrome is another X-linked dominant disorder with features similar to IP.

A 4-day-old female neonate presented to the dermatology clinic with a vesicular eruption on the left leg of 1 day's duration. The eruption was asymptomatic without any extracutaneous findings. This term infant was born without complication, and the mother denied any symptoms consistent with herpes simplex virus infection. Physical examination revealed yellow-red vesicles on an erythematous base in a blaschkoid distribution on the left leg. The rest of the examination was unremarkable. Herpes simplex virus polymerase chain reaction testing was negative.

Prioritize oral health in children with DEB

Preventive oral health should be high on the agenda when managing babies and children with dystrophic epidermolysis bullosa (DEB), pediatric dentist Susanne Krämer told attendees at the first EB World Congress.

While it may not be the first thing on the minds of families coming to terms with their children having a chronic and potentially debilitating skin disease, it is important to consider oral health early to ensure healthy dentition and mouth function, both of which will affect the ability to eat and thus nutrition.

When there are a lot of other health issues, “dentistry is not a priority,” Dr. Krämer acknowledged in an interview at the meeting, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA). 

Something as simple as brushing teeth can be very distressing for parents of a child with EB, she observed, especially if there is dysphagia and toothpaste may be getting into the airways accidentally.

Oral health was one of the topics that patients with EB and their families said would be good to have some guidance on when they were surveyed by DEBRA International. This led the charity to develop its first clinical practice guideline in 2012. Dr. Krämer was the lead author of the guidelines, which are about to be updated and republished.

The “Oral Health for Patients with Epidermolysis Bullosa – Best Clinical Practice Guidelines” (Int J Paediatr Dent. 2012;22 Suppl 1:1-35) are in the final stages of being revised, said Dr. Krämer, who is head of the department of pediatric dentistry at the University of Chile in Santiago. Although there is not much new evidence since the guidelines were first published, “we do have a lot of new technologies within dentistry that can aid the care of EB,” she said.

 

 


An important addition to the upcoming 2020 guidelines is a chapter on the patient-clinician partnership. This was added because “you can have fantastic technologies, but if you don’t have a confident relationship with the family and the patient, you won’t be able to proceed.” Dr. Krämer explained: “Patients with EB are so fragile and so afraid of being hurt that they won’t open their mouth unless there is a confidence with the clinician and they trust [him or her]; once they trust, they [will] open the mouth and you can work.”

Dr. Krämer noted that timing of the first dental appointment will depend on the referral pathway for every country and then every service. In her specialist practice the aim is to see newly diagnosed babies before the age of 3 months. “Lots of people would argue they don’t have teeth, but I need to educate the families on several aspects of oral health from early on.”

Older patients with EB may be more aware of the importance of a healthy mouth from a functional point of view and the need to eat and swallow normally, Dr. Krämer said, adding that the “social aspects of having a healthy smile are very important as well.”

Oral care in EB has come a long way since the 1970s when teeth extraction was recommended as the primary dental treatment option. “If you refer to literature in the 90s, that said we can actually restore the teeth in the patients with EB, and what we are now saying is that we have to prevent oral disease,” Dr. Krämer said.

Can oral disease be prevented completely? Yes, she said, but only in a few patients. “We still have decay in a lot of our patients, but far less than what we have had before. It will depend on the compliance of the family and the patient,” Dr. Krämer noted.

Compliance also is a factor in improving mouth function after surgery, which may be done to prevent the tongue from fusing to the bottom of the mouth and to relieve or prevent microstomia, which limits mouth opening.

“We are doing a lot of surgeries to release the fibrotic scars ... we have done it in both children and adults, but there have been better results in adults, because they are able to comply with the course of exercises” after surgery, Dr. Krämer said.

Results of an as-yet unpublished randomized controlled trial of postoperative mouth exercises demonstrate that patients who did the exercises, which involved using a device to stretch the mouth three times a day for 3 months, saw improvements in mouth opening. Once they stopped doing the exercises, however, these improvements faded. Considering the time spent on dressing changes and other exercises, this is perhaps understandable, she acknowledged.

Prevention, education, continual follow-up, and early referral are key to good oral health, Dr. Krämer emphasized. “If there is patient-clinician partnership confidence, they can have regular checkups with dental cleaning, with a fluoride varnish, different preventive strategies so they do not need to get to the point where they need general anesthesia or extractions.” Extractions still will be done, she added, but more for orthodontic reasons, because the teeth do not fit in the mouth. “That is our ideal world, that is where we want to go.”
