LAKE BUENA VISTA, FLA. – Patient Reported Outcomes Measurement Information System (PROMIS) tools developed by the National Institutes of Health provide particularly useful information for managing rheumatology patients, according to Jeffrey Curtis, MD.

The PROMIS tools – which like most patient-reported outcome (PRO) measurement tools are designed to evaluate and monitor physical, mental, and social health – can be used both for the general population and for individuals living with chronic conditions, Dr. Curtis, professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham (UAB), said at the annual meeting of the Florida Society of Rheumatology.

The tools take a deeper dive into various symptoms and their effects; for instance, with respect to physical health, they measure fatigue, physical function, sleep disturbance, pain intensity, and pain interference – the extent to which pain “messes your patient’s life up,” explained Dr. Curtis, who also is codirector of the UAB Pharmacoepidemiology and Pharmacoeconomics Unit.

Additional physical health domains that PROs measure include dyspnea, gastrointestinal symptoms, pain behavior, pain quality, sexual function, and sleep-related impairment.

These are “things that, honestly, we don’t talk about much as a field, but absolutely affect patients with autoimmune diseases,” he said. “You know, sexual function – that doesn’t come up in my practice spontaneously very often, but there are ways you can quantify that, and for many patients that’s actually a big deal.”

The domains measured by PROMIS tools for mental health look at anxiety and depression, but also delve into alcohol use, anger, cognitive function, life satisfaction, self-efficacy for managing chronic conditions, substance use, and more. The domains for social health address ability to participate in social roles and activities, as well as companionship, satisfaction with social roles and activity, social isolation, and social support.

“You can’t go on a hike with friends [and] be far from a bathroom, because you have bad arthritis and you have Crohn’s disease. Well, that’s kind of an important thing that may or may not come up in your discussions about inflammatory arthritis associated with [inflammatory bowel disease],” he said.

Another example is a patient who is embarrassed attending social functions or wearing a swimsuit because of really bad psoriasis.

“These are the kinds of things that I’m suggesting you and I probably want to measure if we’re providing holistic care to rheumatology patients,” Dr. Curtis said.

The PROMIS tools provide a simple, user-friendly means for doing so in English, Spanish, and many other languages, he noted.

All the scales use the same 1-100 scoring range, which simplifies measurements. They are available for free by download and can be printed or used electronically for use in the office, at home, on the web, and via smartphone.

The NIH developed the PROMIS tools several years ago and validated them for multiple chronic disease populations, Dr. Curtis said, adding that the tools include multiple individual domains and overall “profiles” of varying lengths.

Most are fixed-length scales that are between 4 and 10 questions and can be completed within 30-60 seconds per scale, so several scales can be completed within 5-10 minutes.

However, some scales are longer and provide greater detail.

“The nice thing is that if you ask a few more questions you can get more precise information – there’s more of a floor and ceiling. You can detect people who do really well. You can distinguish between the marathon runners and the 5K-ers and the people who can walk 2 miles but aren’t going to run a race,” he explained.

Further, the PROMIS tools, like the 36-item Short Form Health Survey (SF-36), are benchmarked against the U.S. adult population, allowing for assessment of how a specific drug or treatment “impacts your arthritis patient on a scale that would also be relevant for somebody who doesn’t have arthritis, they have diabetes.”

The metrics and scales are the same, and that can be helpful when trying to get a payer to pay for a particular drug, he said.

“None of these are rheumatology specific; this puts PROs into a language that can help rheumatology contend for the value of the care that we provide on a scale that would be relevant for any other chronic illness, even for nonrheumatology patients,” he explained.

In addition, minimally important differences (group mean change of about 2-3 units) and minimally clinical important differences for individuals (5 units) have been established.

“So we know what the numbers mean, and this is true for all of the scales,” he said.

PROMIS tools also include computer-adaptive testing (CAT) versions, which helps to personalize the scales to provide more precise information for a given patient and eliminate irrelevant information.

Of note, PROMIS health measures are among the data that can be tracked on a smartphone using Arthritis Power, an arthritis research registry developed with the help of a recent infrastructure grant awarded to the Center for Education and Research and Therapeutics of Musculoskeletal Disorders at UAB, Dr. Curtis said.


The measures were also shown in the AWARE study to track closely with other measures, including the Clinical Disease Activity Index (CDAI), and with patient improvement on therapy.

“So these PROMIS scores are tracking with things that you and I are familiar with ... and it looks like these scores are faithfully tracking, over time, patients getting better on therapies that we would expect them to,” he said. “I think this is additional validation – not just from the National Institutes of Health and a decade of research by lots of different groups, but in our own field – that these actually correlate with disease activity ... and that when you start an effective therapy like a [tumor necrosis factor inhibitor] they’re going to improve as you would anticipate.”

Dr. Curtis reported funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and the Patient-Centered Outcomes Research Institute. He has also consulted for or received research grants from Amgen, AbbVie, Bristol-Myers Squibb, CORRONA, Lilly, Janssen, Myriad, Novartis, Roche, Pfizer, and Sanofi/Regeneron.

SEATTLE – The more concentrated urine is in newborns, the more you can trust negative nitrite tests to rule out urinary tract infections, according to investigators at the University of Texas Health Science Center, Houston.

M. Alexander Otto/MDedge News

The researchers found that urine testing negative for nitrites with a specific gravity above 1.015 in children up to 2 months old had a sensitivity of 53% for ruling out UTIs, but that urine with a specific gravity below that mark had a sensitivity of just 14%. The finding “should be taken into account when interpreting nitrite results ... in this high-risk population,” they concluded.

Bacteria in the bladder convert nitrates to nitrites, so positive results are pretty much pathognomonic for UTIs, with a specificity of nearly 100%, according to the researchers.

Negative results, however, don’t reliably rule out infection, and are even less reliable in infants because they urinate frequently, which means they usually flush out bacteria before they have enough time to make the conversion, which takes several hours, they said.

The lead investigator Raymond Parlar-Chun, MD, an assistant professor of pediatrics at the University of Texas McGovern Medical School in Houston, said he had a hunch that negative results might be more reliable when newborns urinate less frequently and have more concentrated urine.

He and his team reviewed data collected on 413 infants up to 2 months old who were admitted for fever workup and treated for UTIs both in the hospital and after discharge. Nitrite results were stratified by urine concentration. A specific gravity of 1.015 was used as the cutoff between concentrated and dilute urine, which was “midway between the parameters reported” in every urinalysis, Dr. Parlar-Chun said.

Although the sensitivity of concentrated urine was only 53%, “it’s a stark difference from” the 14% in dilute urine, he said.“You should take a look at specific gravity to interpret nitrites. If urine is concentrated, you have [more confidence] that you don’t have a UTI if you’re negative. It’s better than taking [nitrites] at face value.”

The subjects were 31 days old, on average, and 62% were boys; 112 had a specific gravity above 1.015, and 301 below.

There was no external funding, and Dr. Parlar-Chun didn’t have any disclosures.

Development of an effective respiratory syncytial virus (RSV) vaccine is feasible using a new technology that can contribute to development of other vaccines as well, according to results of a proof-of-concept study in Science.

The new method of protein engineering preserves the RSV antigen protein’s prefusion structure, including the epitope, thereby inducing antibodies that better “match,” and neutralize, the actual pathogen.

“Protein-based RSV vaccines have had a particularly complicated history, especially those in which the primary immunogen has been the fusion (F) glycoprotein, which exists in two major conformational states: prefusion (pre-F) and postfusion (post-F),” lead author Michelle Crank, MD, of the Vaccine Research Center at the National Institute of Allergy and Infectious Diseases in Bethesda, Md., and her colleagues explained in the paper.

Since the failure of the whole-inactivated RSV vaccine in the 1960s, researchers have focused on F subunit vaccine candidates, but these contain only post-F or “structurally undefined” F protein.

“Although the products are immunogenic, a substantial proportion of antibodies elicited are non- or poorly neutralizing, and field trials have shown no or minimal efficacy,” the authors wrote.

But now researchers have an “atomic-level understanding of F conformational states, antigenic sites, and the specificity of the human B cell repertoire and serum antibody response to infection.” Having developed a way to engineer proteins to retain the F protein’s prefusion conformation, the researchers developed the DS-Cav1 vaccine with an F protein from RSV subtype A.

In their phase 1, randomized, open-label clinical trial, the researchers tested the safety, tolerability and immunogenicity of DS-Cav1. The trial involved 90 healthy adults, aged 18-50, who had no abnormal findings in clinical lab tests, their medical history, or a physical exam.

The participants received two intramuscular doses, 12 weeks apart, of either 50 mcg, 150 mcg or 500 mcg of the vaccine. In each of these dosage groups, half the participants received a vaccine with 0.5 mcg of alum as an adjuvant, and half received a vaccine without any adjuvants. Each of the six randomized dosage-adjuvant groups had 15 participants.

The investigators report on safety and immunogenicity through 28 days after the first vaccine dose among the first 40 participants enrolled, each randomly assigned into four groups of 10 for the 50 mcg and 150 mcg doses with and without the adjuvant. Their primary immunogenicity endpoint was neutralizing activity from the vaccine.

Neutralizing activity with RSV A was seven times higher with 50 mcg and 12-15 times higher with 150 mcg at week 4 than at baseline (P less than .001).

“These increases in neutralizing activity were higher than those previously reported for F protein subunit vaccines and exceeded the threefold increase in neutralization reported after experimental human challenge with RSV,” the authors noted. Neutralization levels remained 5-10 times higher than baseline at week 12 (P less than .001).

Even with RSV B, neutralizing activity from DS-Cav1 was 4-6 times greater with 50 mcg and 9 times greater with 150 mcg, both with and without alum (P less than .001).

“The boost in neutralizing activity to subtype B after a single immunization with a subtype A–based F vaccine reflected the high conservation of F between subtypes and suggested that multiple prior infections by both RSV A and B subtypes establishes a broad preexisting B-cell repertoire,” the authors wrote.

The adjuvant had no clinically significant effect on immunogenicity, and no serious adverse events occurred in the groups.

The findings reveal that DS-Cav1 induces antibodies far more functionally effective than seen in previous RSV vaccines while opening the door to using similar techniques with other vaccines, the authors wrote. “We are now entering an era of vaccinology in which new technologies provide avenues to define the structural basis of antigenicity and to rapidly isolate and characterize human monoclonal antibodies,” the researchers wrote, marking “a step toward a future of precision vaccines.”

The research was funded by the National Institutes of Health and the Bill & Melinda Gates Foundation. Several of the study authors are inventors on patents for stabilizing the RSV F protein.

Each of the six randomized dosage-adjuvant groups had 15 participants.

The investigators report on safety and immunogenicity through 28 days after the first vaccine dose among the first 40 participants enrolled, each randomly assigned into four groups of 10 for the 50 mcg and 150 mcg doses with and without the adjuvant. Their primary immunogenicity endpoint was neutralizing activity from the vaccine.

Neutralizing activity with RSV A was seven times higher with 50 mcg and 12-15 times higher with 150 mcg at week 4 than at baseline (P less than .001).

“These increases in neutralizing activity were higher than those previously reported for F protein subunit vaccines and exceeded the threefold increase in neutralization reported after experimental human challenge with RSV,” the authors noted. Neutralization levels remained 5-10 times higher than baseline at week 12 (P less than .001).

Even with RSV B, neutralizing activity from DS-Cav1 was 4-6 times greater with 50 mcg and 9 times greater with 150 mcg, both with and without alum (P less than .001).

“The boost in neutralizing activity to subtype B after a single immunization with a subtype A–based F vaccine reflected the high conservation of F between subtypes and suggested that multiple prior infections by both RSV A and B subtypes establishes a broad preexisting B-cell repertoire,” the authors wrote.

The adjuvant had no clinically significant effect on immunogenicity, and no serious adverse events occurred in the groups.

The findings reveal that DS-Cav1 induces antibodies far more functionally effective than seen in previous RSV vaccines while opening the door to using similar techniques with other vaccines, the authors wrote. “We are now entering an era of vaccinology in which new technologies provide avenues to define the structural basis of antigenicity and to rapidly isolate and characterize human monoclonal antibodies,” the researchers wrote, marking “a step toward a future of precision vaccines.”

The research was funded by the National Institutes of Health and the Bill & Melinda Gates Foundation. Several of the study authors are inventors on patents for stabilizing the RSV F protein.

LJUBLJANA, SLOVENIA – Staphylococcus aureus resistance to vancomycin is not a one-way street ending in a cliff plunge, as demonstrated by the encouraging experience at a German university children’s hospital, Johannes Huebner, MD, reported at the annual meeting of the European Society for Paediatric Infectious Diseases.

He presented a retrospective analysis of S. aureus isolates obtained from 540 patients at the Dr. von Hauner Children’s Hospital, Munich, from 2002 to 2017. All were either newly identified methicillin-resistant S. aureus (MRSA) or specimens from bacteremic children with invasive MRSA or methicillin-sensitive S. aureus (MSSA). The strains were tested for vancomycin resistance and minimum inhibitory concentration (MIC). The results from the 200 isolates obtained from 2002 to 2009 were then compared to the 340 specimens from 2010 to 2017, when antibiotic stewardship programs rose to the fore at the pediatric hospital.

All samples proved to be vancomycin sensitive. The further good news was there was absolutely no evidence of the worrisome vancomycin MIC creep that has been described at some centers. On the contrary, the MIC was significantly lower in the later samples, at 0.99 mcg/mL, compared with 1.11 mcg/mL in the earlier period. Moreover, the prevalence of heterogeneous glycopeptide-intermediate S. aureus (hGISA) – a phenotype that has been associated with increased rates of treatment failure – improved from 25% in the earlier period to 6% during the later period, reported Dr. Huebner, head of the division of pediatric infectious diseases at the children’s hospital, part of the University of Munich.

Vancomycin MICs weren’t significantly different between the MRSA and MSSA samples.

Based upon this favorable institutional experience, vancomycin remains the first-line treatment for suspected severe gram-positive cocci infections as well as proven infections involving MRSA at Dr. von Hauner Children’s Hospital.

These vancomycin MIC and hGISA data underscore the importance of periodically monitoring local S. aureus antimicrobial susceptibilities, which, as in this case, can differ from the broader global trends. The vancomycin MIC creep issue hadn’t been studied previously in German hospitals, according to Dr. Huebner.

He and his coworkers have published details of the elements of pediatric antibiotic stewardship programs they have found to be most effective (Infection. 2017 Aug;45[4]:493-504) as well as a systematic review of studies on the favorable economic impact of such programs (J Hosp Infect. 2019 Aug;102[4]:369-376).

Dr. Huebner reported having no financial conflicts regarding his study, which was conducted free of commercial support.

The Diagnosis: Juvenile Xanthogranuloma

Juvenile xanthogranuloma (JXG) was first described in 1905 by Adamson1 as solitary or multiple plaquiform or nodular lesions that are yellow to yellowish brown. In 1954, Helwig and Hackney² coined the term juvenile xanthogranuloma to define this histiocytic cutaneous granulomatous tumor.

Juvenile xanthogranuloma is a rare dermatologic disorder that may be present at birth and primarily affects infants and young children. The benign lesions generally occur in the first 4 years of life, with a median age of onset of 2 years.³ Lesions range in size from millimeters to several centimeters in diameter.⁴ The skin of the head and neck is the most commonly involved site in JXG. The most frequent noncutaneous site of JXG involvement is the eye, particularly the iris, accounting for 0.4% of cases.^5,6 Extracutaneous sites such as the heart, liver, lungs, spleen, oral cavity, and brain also may be involved.⁴

Most children with JXG are asymptomatic. Skin lesions present as well-demarcated, rubbery, tan-orange papules or nodules. They usually are solitary, and multiple nodules can increase the risk for extracutaneous involvement.⁴ A case series of patients with neurofibromatosis type 1 showed 14 of 77 (18%) patients examined in the first year of life presented with JXG or other non–Langerhans cell histiocytosis.⁷ The adult form of cutaneous xanthogranuloma often presents with severe bronchial asthma.⁸

Histopathologic examination of a biopsy of the lesion typically demonstrates well-circumscribed nodules with dense infiltrates of polyhedral histiocytes with vaculoles.^3-7 In 85% of cases, Touton giant cells are present.^4,9 A prominent vascular network often is present, which was observed in our patient’s biopsy (Figure 1). Immunohistochemistry typically is positive for CD14, CD68, CD163, fascin, and factor XIIIa.^4,10 Classically, the cells are negative for S-100 and CD1a, which differentiates these lesions from Langerhans cell histiocytosis.^4-7,10 Our patient demonstrated scattered S-100–positive cells representing background dendritic cells and macrophages (Figure 2). The remainder of the clinical, morphologic, and immunophenotypic findings were consistent with non–Langerhans cell histiocytosis, specifically JXG.

Biopsy should be performed in all cases, and basic laboratory test results such as a complete blood cell count and basic metabolic panel also are appropriate. Routine referral of all patients with cutaneous JXG for ophthalmologic evaluation is not recommended.¹¹ Most patients with ocular involvement present with acute ocular concerns; asymptomatic eye involvement is rare. It is reasonable to consider referral to ophthalmology for patients younger than 2 years who present with multiple lesions, as they may have a higher risk for ocular involvement.¹¹

Juvenile xanthogranuloma usually is a benign disorder with management involving observation, as the lesions typically involute spontaneously.^3-7,9,10,12 Systemic or intralesional corticosteroids may be used for treatment in lesions that do not resolve. Ocular JXG refractory to steroid treatment has been managed in several cases with intravitreal bevacizumab.¹³ Additionally, surgical excision can be considered if malignancy is suspected, the lesion does not resolve with observation or steroid treatment, or the lesion is located near vital structures.^4-7,9-13

Spitz nevus presents as a single dome-shaped papule, but histology shows a symmetrical proliferation of spindle and epithelioid cells. Trachoma can present in and around the eye as a follicular hypertrophy but most commonly is seen in the conjunctiva. Dermoid cysts present as solitary subcutaneous cystic lesions; histology demonstrates a lining of keratinizing squamous epithelium with the presence of pilosebaceous structures. Dermatofibroma appears as a tan to reddish-brown papule in an area of prior minor trauma; pathology demonstrates an acanthotic epidermis with an underlying zone of normal papillary dermis and unencapsulated lesions with spindle cells overlapping in fascicles and whorls at the periphery.

SEATTLE – Intravenous fluids can simply be stopped after children with acute viral gastroenteritis are rehydrated in the hospital; there’s no need for a slow wean, according to a review at the Connecticut Children’s Medical Center, Hartford.

Researchers found that children leave the hospital hours sooner, with no ill effects. “This study suggests that slowly weaning IV fluids may not be necessary,” said lead investigator Danielle Klima, DO, a University of Connecticut pediatrics resident.

The team at Connecticut Children’s noticed that weaning practices after gastroenteritis rehydration varied widely on the pediatric floors, and appeared to be largely provider dependent, with “much subjective decision making.” The team wanted to see if it made a difference one way or the other, Dr. Klima said at Pediatric Hospital Medicine.

During respiratory season, “our pediatric floors are surging. Saving even a couple hours to get these kids out” quicker matters, she said, noting that it’s likely the first time the issue has been studied.

The team reviewed 153 children aged 2 months to 18 years, 95 of whom had IV fluids stopped once physicians deemed they were fluid resuscitated and ready for an oral feeding trial; the other 58 were weaned, with at least two reductions by half before final discontinuation.

There were no significant differences in age, gender, race, or insurance type between the two groups. The mean age was 2.6 years, and there were slightly more boys. The ED triage level was a mean of 3.2 points in both groups on a scale of 1-5, with 1 being the most urgent. Children with serious comorbidities, chronic diarrhea, feeding tubes, severe electrolyte abnormalities, or feeding problems were among those excluded.

Overall length of stay was 36 hours in the stop group versus 40.5 hours in the weaning group (P = .004). Children left the hospital about 6 hours after IV fluids were discontinued, versus 26 hours after weaning was started (P less than .001).

Electrolyte abnormalities on admission were more common in the weaning group (65% versus 57%), but not significantly so (P = .541). Electrolyte abnormalities were also more common at the end of fluid resuscitation in the weaning arm, but again not significantly (65% 42%, P = .077).

Fluid resuscitation needed to be restarted in 15 children in the stop group (16%), versus 11 (19%) in the wean arm (P = .459). One child in the stop group (1%) versus four (7%) who were weaned were readmitted to the hospital within a week for acute viral gastroenteritis (P = .067).

“I expected we were taking a more conservative weaning approach in younger infants,” but age didn’t seem to affect whether patients were weaned or not, Dr. Klima said.

With the results in hand, “our group is taking a closer look at exactly what we are doing,” perhaps with an eye toward standardization or even a randomized trial, she said.

She noted that weaning still makes sense for a fussy toddler who refuses to take anything by mouth.

There was no external funding, and Dr. Klima had no disclosures. The conference was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

AUSTIN, TEX. – All too often, children and adolescents stumble on their way to adult health care – if they make it at all.

In fact, data from an ongoing survey by the Department of Health & Human Services and the Health Resources and Services Administration indicate that only 40% of children with special health care needs aged 12-17 years receive the services necessary to make transitions to adult health care.

“Most fall off the proverbial cliff and do not engage with adult providers,” Cynthia Peacock, MD, said at the annual meeting of the Society for Pediatric Dermatology. She recalled meeting with one individual who, after being a patient at the children’s hospital for 13 years, was told over the phone to transition to an adult provider with not so much as a promised letter of introduction being sent on. “She did not know about the adult health care culture, which is fractured in care, relies on the patient to be their own advocate, and wants patients to be able to do their visit in 10-15 minutes.”

Dr. Peacock, medical director of the Transition Medicine Clinic at Baylor College of Medicine, Houston, described transition health care as a purposeful, planned migration from child-oriented to adult-oriented health care, a process that should start as early as possible. “Starting at age 12 is not too early,” she said. “It gives you time so that you can keep introducing the concept when that individual keeps coming back to see you, especially if it’s a chronic condition.”

She recommended that clinicians ask several questions to assess transition readiness of pediatric patients to adult care, including, Do you know your medications? Do you know how to take them? Do you know how to refill them? Do you know how to discuss them? Can you discuss your medical condition with the adult doctor? Can you call for a doctor’s appointment or get a prescription filled? “Adolescents are notorious for calling [the doctor’s office], and if they’re told they can’t make an appointment, that’s it; they stop right there,” Dr. Peacock said. “They don’t tend to problem solve. They don’t engage.”

Studies have suggested that the transfer of care is more likely to be successful if a formal transition program is in place to prepare the patient and to facilitate the change in health care providers. “There is a growing evidence base in the literature that skills training for young people with chronic illnesses can be associated with positive outcomes,” she said. “This can be as easy as telling the individual, ‘Do a book report about your condition. Talk to a friend. Tell a friend what your condition is. Or, do school science fair project and talk to your class about what you have.’ Get them past that uncomfortable feeling of having to talk about it.”

The earlier this happens, the better. “We know from research that if you get them to be their own [health care] advocate, that’s one less thing they have to do in the adult health care system,” she said. “They will move on to other things, such as getting a job or going to college.”

Dr. Peacock, who is board certified in pediatrics and internal medicine, added that providing adolescents with the option of being seen by professionals without their parents is considered best practice. “You could start by introducing the concept at age 12, but say at age 13, ‘I want to spend a minute with you alone without your parent. I want you to bring in questions that you want to ask me that you may not want to ask in front of your parents,’” she said. “I guarantee you that on that third visit the adolescent will ask you a question.”

Optimistic messaging is another component of effective planning. “You may see someone in your office with a disease that you know has high mortality and high morbidity, and you’re trying to help the family cope,” Dr. Peacock said. “That young person needs to be asked, ‘What are your plans for your future?’ Think about it: In 10 or 20 years when you’re transitioning that individual out of your health care system, what medical miracles have happened?” She recalled visiting with the mother of a patient with Down syndrome who had significant congenital heart disease. He was in his 30s and struggled to keep his behavior in check. “We were trying to develop a behavior plan, but his past care team had never put one in place for him,” Dr. Peacock said. “The mother looked at me and said, accusingly, ‘It’s your fault. It’s all of your doctors’ faults because they never told me that this would happen. They told me to take him home and spoil him because he would not be around at this age.’”

Effective transition handoffs are collaborative, she continued, with care plans built around what is likely to happen with the patient over time. “At Baylor College of Medicine, pediatric dermatologists follow patients for life, but I take over everything else adult care related,” Dr. Peacock said. “The pediatric dermatologist has me come over to the hospital when we’re talking about quality-of-life issues – about advance care, advanced directives, those types of things.”


She recommends not transferring care to an adult provider during pregnancy, hospitalization, during active disease, or during changes to a patient’s medical therapy. “When pediatricians call me from the hospital and they want an urgent transfer, I tell them, ‘Your emergency is not my urgency. Get everything ready; get them discharged. Get them followed up and back on their chronic care management, and I’ll be happy to do that transition for you,’ ” she said. “It’s also good to leave that door open for the adult provider to call you. Give them your cell phone number because it may be just one question, like, ‘Can you tell me why his liver enzymes are elevated? We can’t figure it out.’ ”

Dr. Peacock advises pediatric providers to develop processes within their own practice that facilitates transfer, “even if it just means sharing information with the adult provider at the end of the time you’re seeing that young adult. Know your systems and your resources. Get that medical summary done, even if it’s making the patient do the medical summary.” More information for clinicians and for patients and their families can be found at www.gottransition.org.

AUSTIN, TEX. – All too often, children and adolescents stumble on their way to adult health care – if they make it at all.

In fact, data from an ongoing survey by the Department of Health & Human Services and the Health Resources and Services Administration indicate that only 40% of children with special health care needs aged 12-17 years receive the services necessary to make transitions to adult health care.

“Most fall off the proverbial cliff and do not engage with adult providers,” Cynthia Peacock, MD, said at the annual meeting of the Society for Pediatric Dermatology. She recalled meeting with one individual who, after being a patient at the children’s hospital for 13 years, was told over the phone to transition to an adult provider with not so much as a promised letter of introduction being sent on. “She did not know about the adult health care culture, which is fractured in care, relies on the patient to be their own advocate, and wants patients to be able to do their visit in 10-15 minutes.”

Dr. Peacock, medical director of the Transition Medicine Clinic at Baylor College of Medicine, Houston, described transition health care as a purposeful, planned migration from child-oriented to adult-oriented health care, a process that should start as early as possible. “Starting at age 12 is not too early,” she said. “It gives you time so that you can keep introducing the concept when that individual keeps coming back to see you, especially if it’s a chronic condition.”

She recommended that clinicians ask several questions to assess transition readiness of pediatric patients to adult care, including, Do you know your medications? Do you know how to take them? Do you know how to refill them? Do you know how to discuss them? Can you discuss your medical condition with the adult doctor? Can you call for a doctor’s appointment or get a prescription filled? “Adolescents are notorious for calling [the doctor’s office], and if they’re told they can’t make an appointment, that’s it; they stop right there,” Dr. Peacock said. “They don’t tend to problem solve. They don’t engage.”

Studies have suggested that the transfer of care is more likely to be successful if a formal transition program is in place to prepare the patient and to facilitate the change in health care providers. “There is a growing evidence base in the literature that skills training for young people with chronic illnesses can be associated with positive outcomes,” she said. “This can be as easy as telling the individual, ‘Do a book report about your condition. Talk to a friend. Tell a friend what your condition is. Or, do school science fair project and talk to your class about what you have.’ Get them past that uncomfortable feeling of having to talk about it.”

The earlier this happens, the better. “We know from research that if you get them to be their own [health care] advocate, that’s one less thing they have to do in the adult health care system,” she said. “They will move on to other things, such as getting a job or going to college.”

BANGKOK – Since founding the Epilepsy Unit at Glasgow’s Western Infirmary 37 years ago, Martin J. Brodie, MD, has seen many changes in the field, including the introduction of more than a dozen new antiepileptic drugs (AEDs) in the past 2 decades.

Bruce Jancin/MDedge News

And based upon this vast clinical experience coupled with his leadership of landmark studies, he has a message for his physician colleagues and their epilepsy patients. And it’s not pretty.

“Has the probability of achieving seizure freedom increased significantly in the last 3 decades? Regrettably, the answer is no,” he declared at the International Epilepsy Congress.

“Over all these years, in terms of seizure freedom there has been no real difference in outcome. There’s really quite a long way to go before we can say that we are doing all that well for people,” he said at the congress sponsored by the International League Against Epilepsy.

In the year 2000, he and his coinvestigators published a prospective, longitudinal, observational cohort study of 470 newly diagnosed patients with epilepsy treated at the Western Infirmary during 1982-1997, all with a minimum of 2 years’ follow-up. Sixty-one percent achieved complete freedom from seizures for at least 1 year on monotherapy, and another 3% did so on polytherapy, for a total rate of 64% (N Engl J Med. 2000 Feb 3;342[5]:314-19).

But these were patients who by and large were treated with older AEDs such as carbamazepine, which has since fallen by the wayside because of toxicities. Scottish neurologists now generally turn to lamotrigine (Lamictal), levetiracetam (Spritam), and other, newer AEDs. So Dr. Brodie and his coworkers recently published a follow-up study, this one featuring 30 years of longitudinal follow-up of 1,795 patients newly treated for epilepsy with AEDs, new and old, during 1982-2012. The investigators demonstrated that the seizure-free survival curves over time were virtually superimposable. In the larger, more recent study, remission was achieved in 55% of patients with AED monotherapy and in another 9% with polytherapy, for a total rate of 64%, identical to the rate in the 2000 study, and as was the case in the earlier study, 36% of patients remained uncontrolled (JAMA Neurol. 2018 Mar 1;75[3]:279-86).


“Overall, the way this population behaves, there’s no difference in efficacy and no difference in tolerability whether you’re using old drugs used properly or new drugs used properly,” said Dr. Brodie, professor of neurology at the University of Glasgow (Scotland).

It’s noteworthy that Sir William R. Gowers, the Londoner who has been called the greatest neurologist of all time, reported a 70% seizure-free rate in 1881, while Dr. Brodie and workers achieved a 64% rate in their 30-year study. “It’s interesting that the numbers are so bad, really, I suppose,” Dr. Brodie commented.

How about outcomes in pediatric epilepsy?

Dr. Brodie and coworkers recently published a 30-year prospective cohort study of 332 adolescent epilepsy patients newly diagnosed and treated at the Western Infirmary during 1982-2012. At the end of the study, 67% were seizure-free for at least the past year, a feat accomplished via monotherapy in 83% of cases. The seizure-free rate was 72% in those with generalized epilepsy, significantly better than the 60% figure in those with focal epilepsy. The efficacy rate was 74% with newer AED monotherapy and similar at 77% with monotherapy older drugs. Adverse event rates ranged from a low of 12% with lamotrigine to 56% with topiramate (Topamax), according to the findings published in Epilepsia (2019 Jun;60[6]:1083-90).

Roughly similar outcomes have been reported from Norway in a study of 600 children with epilepsy, median age 7 years, with a median follow-up of 5.8 years that is considerably shorter than that in the Glasgow pediatric study. Overall, 59% of the Norwegian children remained seizure free for at least 1 year, 30% developed drug-resistant epilepsy, and 11% followed an intermediate remitting/relapsing course (Pediatrics. 2018 Jun. doi: 10.1542/peds.2017-4016).
 

Why the decades of flat pharmacologic outcomes?

The consistently suboptimal seizure-free outcomes obtained over the past 30 years shouldn’t really be surprising, according to Dr. Brodie.

“Although we think we have lots of mechanisms of action and lots of differences between the drugs, they’re arguably all antiseizure drugs and not antiepilepsy drugs. We don’t treat the whale; we treat the spout. We don’t treat what we cannot see; we treat what we can see, which is the seizures, but we’re not influencing the long-term outcome,” the neurologist explained.
 

The compelling case for early epilepsy surgery

Epilepsy surgery remains underutilized, according to Dr. Brodie and other experts.

The International League Against Epilepsy defines drug-resistant epilepsy as failure to achieve sustained seizure freedom after adequate trials of two tolerated and appropriately chosen and used AED schedules. Dr. Brodie’s work was influential in creating that definition because his data demonstrated the sharply diminishing returns of additional drug trials.

“When do we consider epilepsy surgery? Arguably, the earlier, the better. After two drugs have failed appropriately, I don’t think anybody in this room would argue about that, although people in some of the other rooms might,” he said at the congress.

Influential in his thinking on this score were the impressive results of an early study, the first-ever randomized trial of surgery for epilepsy. In 80 patients with a 21-year history of drug-refractory temporal lobe epilepsy who were randomized to surgery or 1 year of AED therapy, at 1 year of follow-up blinded epileptologists rated 58% of surgically treated patients as free from seizures that impair awareness of self and surroundings, compared with just 8% in the AED group (N Engl J Med. 2001 Aug 2;345[5]:311-8).

“That’s a big outcome, and I’m very keen to ensure that my data continue to drive the push for early surgery,” according to the neurologist.

A Cochrane review of 177 studies totaling more than 16,000 patients concluded that 65% of epilepsy patients had good outcomes following surgery. Prognostic factors associated with better surgical outcomes included complete surgical resection of the epileptogenic focus, the presence of mesial temporal sclerosis, concordance of MRI and EEG findings, and an absence of cortical dysplasia (Cochrane Database Syst Rev. 2019;6:CD010541. doi: 10.1002/14651858.CD010541.pub3).

In addition, a systematic review and meta-analysis by Canadian investigators found that 72% of adults with lesional epilepsy identified by MRI or histopathology were seizure-free after surgery, compared with 36% of those with nonlesional epilepsy. The disparity in outcomes was similar in pediatric epilepsy patients, with seizure freedom after surgery in 74% of those with lesional disease versus 45% with nonlesional epilepsy (Epilepsy Res. 2010 May;89[2-3]:310-8).
 

Whither are neurostimulatory device therapies headed?

Dr. Brodie was quick to admit that as a pharmacologic researcher, device modalities including vagus nerve stimulation, responsive neurostimulation, and deep brain stimulation are outside his area of expertise. But he’s been following developments in the field with interest.

“These device therapies have shown efficacy in short-term randomized trials, but very few patients attain long-term seizure freedom. I think these are largely palliative techniques. I gave up on these techniques a long time ago because I felt it was a very costly way of reducing seizures by a relatively small margin, and really we need to go a little bit further than that. But I know there’s a lot of work going on at the moment,” he said.

Dr. Brodie reported serving on the scientific advisory boards of more than a half dozen pharmaceutical companies.

“Overall, the way this population behaves, there’s no difference in efficacy and no difference in tolerability whether you’re using old drugs used properly or new drugs used properly,” said Dr. Brodie, professor of neurology at the University of Glasgow (Scotland).

It’s noteworthy that Sir William R. Gowers, the Londoner who has been called the greatest neurologist of all time, reported a 70% seizure-free rate in 1881, while Dr. Brodie and workers achieved a 64% rate in their 30-year study. “It’s interesting that the numbers are so bad, really, I suppose,” Dr. Brodie commented.

How about outcomes in pediatric epilepsy?

Dr. Brodie and coworkers recently published a 30-year prospective cohort study of 332 adolescent epilepsy patients newly diagnosed and treated at the Western Infirmary during 1982-2012. At the end of the study, 67% were seizure-free for at least the past year, a feat accomplished via monotherapy in 83% of cases. The seizure-free rate was 72% in those with generalized epilepsy, significantly better than the 60% figure in those with focal epilepsy. The efficacy rate was 74% with newer AED monotherapy and similar at 77% with monotherapy older drugs. Adverse event rates ranged from a low of 12% with lamotrigine to 56% with topiramate (Topamax), according to the findings published in Epilepsia (2019 Jun;60[6]:1083-90).

Roughly similar outcomes have been reported from Norway in a study of 600 children with epilepsy, median age 7 years, with a median follow-up of 5.8 years that is considerably shorter than that in the Glasgow pediatric study. Overall, 59% of the Norwegian children remained seizure free for at least 1 year, 30% developed drug-resistant epilepsy, and 11% followed an intermediate remitting/relapsing course (Pediatrics. 2018 Jun. doi: 10.1542/peds.2017-4016).
 

Why the decades of flat pharmacologic outcomes?

The consistently suboptimal seizure-free outcomes obtained over the past 30 years shouldn’t really be surprising, according to Dr. Brodie.

“Although we think we have lots of mechanisms of action and lots of differences between the drugs, they’re arguably all antiseizure drugs and not antiepilepsy drugs. We don’t treat the whale; we treat the spout. We don’t treat what we cannot see; we treat what we can see, which is the seizures, but we’re not influencing the long-term outcome,” the neurologist explained.
 

The compelling case for early epilepsy surgery

Epilepsy surgery remains underutilized, according to Dr. Brodie and other experts.

The International League Against Epilepsy defines drug-resistant epilepsy as failure to achieve sustained seizure freedom after adequate trials of two tolerated and appropriately chosen and used AED schedules. Dr. Brodie’s work was influential in creating that definition because his data demonstrated the sharply diminishing returns of additional drug trials.

“When do we consider epilepsy surgery? Arguably, the earlier, the better. After two drugs have failed appropriately, I don’t think anybody in this room would argue about that, although people in some of the other rooms might,” he said at the congress.

Influential in his thinking on this score were the impressive results of an early study, the first-ever randomized trial of surgery for epilepsy. In 80 patients with a 21-year history of drug-refractory temporal lobe epilepsy who were randomized to surgery or 1 year of AED therapy, at 1 year of follow-up blinded epileptologists rated 58% of surgically treated patients as free from seizures that impair awareness of self and surroundings, compared with just 8% in the AED group (N Engl J Med. 2001 Aug 2;345[5]:311-8).

“That’s a big outcome, and I’m very keen to ensure that my data continue to drive the push for early surgery,” according to the neurologist.

A Cochrane review of 177 studies totaling more than 16,000 patients concluded that 65% of epilepsy patients had good outcomes following surgery. Prognostic factors associated with better surgical outcomes included complete surgical resection of the epileptogenic focus, the presence of mesial temporal sclerosis, concordance of MRI and EEG findings, and an absence of cortical dysplasia (Cochrane Database Syst Rev. 2019;6:CD010541. doi: 10.1002/14651858.CD010541.pub3).

In addition, a systematic review and meta-analysis by Canadian investigators found that 72% of adults with lesional epilepsy identified by MRI or histopathology were seizure-free after surgery, compared with 36% of those with nonlesional epilepsy. The disparity in outcomes was similar in pediatric epilepsy patients, with seizure freedom after surgery in 74% of those with lesional disease versus 45% with nonlesional epilepsy (Epilepsy Res. 2010 May;89[2-3]:310-8).
 

Whither are neurostimulatory device therapies headed?

Dr. Brodie was quick to admit that as a pharmacologic researcher, device modalities including vagus nerve stimulation, responsive neurostimulation, and deep brain stimulation are outside his area of expertise. But he’s been following developments in the field with interest.

“These device therapies have shown efficacy in short-term randomized trials, but very few patients attain long-term seizure freedom. I think these are largely palliative techniques. I gave up on these techniques a long time ago because I felt it was a very costly way of reducing seizures by a relatively small margin, and really we need to go a little bit further than that. But I know there’s a lot of work going on at the moment,” he said.

Dr. Brodie reported serving on the scientific advisory boards of more than a half dozen pharmaceutical companies.

SEATTLE – Blood cultures were ordered for over half of pediatric skin infection encounters across 38 children’s hospitals, with rates varying from about 20% to 80% between hospitals, according to a review of almost 50,000 encounters in the Pediatric Health Information System database.

M. Alexander Otto/MDedge News

It was a surprising finding, because current guidelines from the Infectious Diseases Society of America do not recommend blood cultures as part of the routine evaluation of uncomplicated pediatric skin and soft-tissue infections (SSTIs), meaning infections in children who are otherwise healthy without neutropenia or other complicating factors.

Just 0.6% of the cultures were positive in the review, and it’s likely some of those were caused by contamination. After adjustment for demographics, complex chronic conditions, and severity of illness, culture draws were associated with a 20% increase in hospital length of stay (LOS), hospital costs, and 30-day readmission rates.

“Our data provide more evidence that [routine] blood cultures for children with SSTI represents low-value practice and should be avoided,” said lead investigator John Stephens, MD, a pediatrics professor and hospitalist at the University of North Carolina at Chapel Hill.

Dr. Stephens became curious about how common the practice was across hospitals after he and a friend penned an article about the issue for the Journal of Hospital Medicine’s “Things We Do for No Reason” series. The single-center studies they reviewed showed similarly high rates of both testing and negative cultures (J Hosp Med. 2018 Jul;13[7]:496-9).

Dr. Stephens and his team queried the Pediatric Health Information System database for encounters in children aged 2 months to 18 years with the diagnostic code 383, “cellulitis and other skin infections,” from 2012 to 2017, during which time “there really wasn’t a change” in IDSA guidance, he noted. Transfers, encounters with ICU care, and immunocompromised children were excluded.

Hospital admissions were included in the review if they had an additional code for erysipelas, cellulitis, impetigo, or other localized skin infection. The rate of positive cultures was inferred from subsequent codes for bacteremia or septicemia.

Across 49,291 encounters, the median rate of blood culture for skin infection was 51.6%, with tremendous variation between hospitals. With blood cultures, the hospital LOS was about 1.9 days, the hospital cost was $4,030, and the 30-day readmission rate was 1.3%. Without cultures, LOS was 1.6 days, the cost was $3,291, and the readmission rate was 1%.

Although infrequent, it’s likely that positive cultures triggered additional work-up, time in the hospital, and other measures, which might help account for the increase in LOS and costs.

As for why blood testing was so common, especially in some hospitals, “I think it’s just institutional culture. No amount of clinical variation in patient population could explain” a 20%-80% “variation across hospitals. It’s really just ingrained habits,” Dr. Stephens said at Pediatric Hospital Medicine.

“The rate of positive blood culture was really low, and the association was for higher cost and utilization. I think this really reinforces the IDSA guidelines. We need to focus on quality improvement efforts to do this better,” he said, noting that he hopes to do so at his own institution.

“I’d also like to know more on the positives. In the single center studies, we know more than half of them are contaminants. Often, there’s more contamination than true positives,” he said at the meeting sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

Instead of routine blood culture, Dr. Stephens recommended in his article to send pus for a Gram stain and culture and sensitivity, while noting that blood cultures remain reasonable for complicated infections, immunocompromised patients, and neonates.

There was no external funding, and Dr. Stephens didn’t report any disclosures.

SEATTLE – There were no cases of aspiration with enteric feeds of 60 children aged up to 2 years on high flow nasal cannula (HFNC) for bronchiolitis at the University of Oklahoma Children’s Hospital, Oklahoma City, according to research presented at the 2019 Pediatric Hospital Medicine Conference.

M. Alexander Otto/MDedge News

HFNC has become common for bronchiolitis management; it often saves infants from intubation. However, many providers opt for total parenteral nutrition during therapy instead of enteral feeding because of concerns about aspiration pneumonia.

Pediatricians at the children’s hospital began to wonder if the concern was really necessary. There have been reports of safe feeding during HFNC, and “clinical care literature has shown that feeding the gut throughout illness improves outcomes,” said lead investigator, Sarah Walter, MD, a third-year pediatrics resident at the hospital.

So her team took a leap of faith. They consulted the HFNC literature, asked their fellow providers what they would be comfortable with, and instituted a pediatric HFNC enteral feeding protocol at the children’s hospital for use on inpatient floors, pediatric ICUs, and elsewhere.

Feedings – formula or breast milk – are triggered by stable respiratory Tal scores over 8 hours, meaning that respiratory rates, breath sounds, and accessory muscle use were stable or improving. Children on a flow of 6 L/min or less, with a respiratory rate below 60 breaths per minute, are started on oral feeds, and those on higher flows on nasogastric (NG) tube feeds.

Feeds are started at 1 mL/kg per hour and advanced by the same amount every 3 hours until volume goals are reached; IV fluids are tapered accordingly. It’s a standing order, so nurses are able to initiate and advance feeding as indicated, any time of day.

Feeding was temporarily suspended in only 17 children: 6 for emesis, 6 for worsening respiratory scores, and the rest for dislodged NG tubes, procedures, or other issues. Enteric feeds were restarted with two stable scores below 7 points, at half the rate at which they were stopped.

NG tubes were used in over half of the 478 nursing shifts during which the 60 children – the majority aged 4-24 months – were fed; oral feeds in more than a third; and gastric tubes and other options in the rest. IV nutrition was used during just 1.8% of the shifts.

Enteric feeds were given up to a flow rate of 3.5 L/kg. There were no aspirations, even when children vomited. “We have seen good results so far that feeding is safe in these children,” Dr. Walters said.

“Our hospitalist team has been very receptive; they have been using the order set pretty continuously.” Parents also feel better when they know their children were “getting food in their belly,” even if by NG tube. “It’s important for family satisfaction,” she said.

The next step is to assess impact on length of stay, and education efforts to encourage broader use of the order set.

There was no external funding, and Dr. Walter had no disclosures. The meeting was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.
