COVID and schools: A pediatrician's case for a return to class
In a time when this country is struggling to find topics on which we can achieve broad consensus, the question of whether in-class learning is important stands as an outlier. Parents, teachers, students, and pediatricians all agree that having children learn in a social, face-to-face environment is critical to their education and mental health. Because school has become a de facto daycare source for many families, employers have joined in the chorus supporting a return to in-class education.
Of course, beyond that basic point of agreement the myriad of questions relating to when and how that return to the educational norm can be achieved we divide into groups with almost as many answers as there are questions. Part of the problem stems from the national leadership vacuum that fed the confusion. In this void the topic of school reopening has become politicized.
On Jan. 5, 2021, the American Academy of Pediatrics released an updated interim COVID-19 Guidance for Safe Schools at services.aap.org. It is a thorough and well thought out document that should function as a roadmap for communities and pediatricians who serve as official and unofficial advisers to their local school departments. At the very outset it reminds us that “school transmission mirrors but does not drive community transmission.”
Unfortunately, timing is everything and while the document’s salient points received some media attention it was mostly buried by the tsunami of press coverage in the wake of the storming of the Capitol the next day and the postinauguration reshuffling of the federal government. Even if it had been released on one of those seldom seen quiet news days, I fear the document’s message encouraging the return to in-class learning would have still not received the attention it deserved.
The lack of a high-visibility celebrity spokesperson and a system of short-tenure presidencies puts the AAP at a disadvantage when it comes to getting its message across to a national audience. The advocacy role filters down to those of us in our own communities who must convince school boards that not only is in-class learning critical but there are safe ways to do it.
In some communities the timing of return to in-class learning may pit pediatricians against teachers. Usually, these two groups share an enthusiastic advocacy for children. However, facing what has up to this point been a poorly defined health risk, teachers are understandably resistant to return to the classroom although they acknowledge its importance.
Armed with the AAP’s guidance document, pediatricians should encourage school boards and state and local health departments to look closely at the epidemiologic evidence and consider creative ways to prioritize teachers for what currently are limited and erratic vaccine supplies. Strategies might include offering vaccines to teachers based strictly on their age and/or health status. However, teachers and in-class education are so critical to the educational process and the national economy that an open offer to all teachers makes more sense.
While some states have already prioritized teachers for vaccines, the AAP must continue to speak loudly that in-class education is critical and urge all states to do what is necessary to make teachers feel safe to return to the classroom.

COVID-19 vaccination recommended for rheumatology patients
People with rheumatic diseases should get vaccinated against SARS-CoV-2 as soon as possible, the American College of Rheumatology (ACR) recommends.
“It may be that people with rheumatic diseases are at increased risk of developing COVID or serious COVID-related complications,” Jonathan Hausmann, MD, assistant professor of medicine at Harvard Medical School, Boston, said in an ACR podcast. “So the need to prevent COVID-19 is incredibly important in this group of patients.”
The guidelines recommend a delay in vaccination only in rare circumstances, such as for patients with very severe illness or who have recently been administered rituximab, Jeffrey R. Curtis, MD, MPH, lead author of the guidelines, said in the podcast.
“Our members have been inundated with questions and concerns from their patients on whether they should receive the vaccine,” ACR President David Karp, MD, PhD, said in a press release.
So the ACR convened a panel of nine rheumatologists, two infectious disease specialists, and two public health experts. Over the course of 8 weeks, the task force reviewed the literature and agreed on recommendations. The organization posted a summary of the guidelines on its website after its board of directors approved it Feb. 8. The paper is pending journal peer review.
Some risks are real
The task force confined its research to the COVID-19 vaccines being offered by Pfizer and Moderna because they are currently the only ones approved by the Food and Drug Administration. It found no reason to distinguish between the two vaccines in its recommendations.
Because little research has directly addressed the question concerning COVID-19 vaccination for patients with rheumatic diseases, the task force extrapolated from data on other vaccinations in people with rheumatic disease and on the COVID-19 vaccinations in other populations.
It analyzed reports that other types of vaccination, such as for influenza, triggered flares of rheumatic conditions. “It is really individual case reports or small cohorts where there may be a somewhat higher incidence of flare, but it’s usually not very large in its magnitude nor duration,” said Dr. Curtis of the University of Alabama at Birmingham.
The task force also considered the possibility that vaccinations could lead to a new autoimmune disorder, such as Guillain-Barré syndrome or Bell palsy. The risk is real, the task force decided, but not significant enough to influence their recommendations.
Likewise, in immunocompromised people, vaccinations with live virus, such as those for shingles, might trigger the infection the vaccination is meant to prevent. But this can’t happen with the Pfizer and Moderna COVID-19 vaccines because they contain messenger RNA instead of live viruses, Dr. Curtis said.
Although it might be optimal to administer the vaccines when rheumatic diseases are quiescent, the urgency of getting vaccinated overrides that consideration, Dr. Curtis said. “By and large, there was a general consensus to not want to delay vaccination until somebody was stable and doing great, because you don’t know how long that’s going to be,” he said.
How well does it work?
One unanswered question is whether the COVID-19 vaccines work as well for patients with rheumatic diseases. The task force was reassured by data showing efficacy across a range of subgroups, including some with immunosenescence, Dr. Curtis said. “But until we have data in rheumatology patients, we’re just not going to know,” he said.
The guidelines specify that some drug regimens be modified when patients are vaccinated.
For patients taking rituximab, vaccination should be delayed, but only for those who are able to maintain safe social distancing to reduce the risk for COVID-19 exposure, Dr. Curtis said. “If somebody has just gotten rituximab recently, it might be more ideal to complete the vaccine series about 2-4 weeks before the next rituximab dose,” he said. “So if you are giving that therapy, say, at 6-month intervals, if you could vaccinate them at around month 5 from the most recent rituximab cycle, that might be more ideal.”
The guidance calls for withholding JAK inhibitors for a week after each vaccine dose is administered.
It calls for holding SQ abatacept 1 week prior and 1 week after the first COVID-19 vaccine dose, with no interruption after the second dose.
For abatacept IV, clinicians should “time vaccine administration so that the first vaccination will occur 4 weeks after abatacept infusion (i.e., the entire dosing interval), and postpone the subsequent abatacept infusion by 1 week (i.e., a 5-week gap in total).” It recommends no medication adjustment for the second vaccine dose.
For cyclophosphamide, the guidance recommends timing administration to occur about a week after each vaccine dose, when feasible.
None of this advice should supersede clinical judgment, Dr. Curtis said.

Strep A and tic worsening: Final word?
Exposure to Group A streptococcus (GAS) does not appear to worsen symptoms of Tourette syndrome and other chronic tic disorders (CTDs) in children and adolescents, new research suggests.
Investigators studied over 700 children and teenagers with CTDs, one-third of whom also had attention deficit hyperactivity disorder and one-third who had obsessive-compulsive disorder (OCD).
The youngsters were followed for an average of 16 months and evaluated at 4-month intervals to see if they were infected with GAS. Tic severity was monitored through telephone interviews, in-person visits, and parental reports.
A little less than half the children experienced worsening of tics during the study period, but the researchers found no association between these exacerbations and GAS exposure.
There was also no link between GAS and worsening OCD. However, researchers did find an association between GAS exposure and an increase in hyperactivity and impulsivity in patients with ADHD.
“This study does not support GAS exposures as contributing factors for tic exacerbations in children with CTD,” the authors note.
“Specific work-up or active management of GAS infections is unlikely to help modifying the course of tics in CTD and is therefore not recommended,” they conclude.
The study was published online in Neurology.
‘Intense debate’
The association between GAS and CTD stems from the description of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection (PANDAS) – a condition that is now incorporated in the pediatric acute neuropsychiatric syndromes (PANS), the authors note. Tics constitute an “accompanying feature” of this condition.
However, neither population-based nor longitudinal clinical studies “could definitely establish if tic exacerbations in CTD are associated with GAS infections,” they note.
“The link between streptococcus and tics in children is still a matter of intense debate,” said study author Davide Martino, MD, PhD, director of the Movement Disorders Program at the University of Calgary (Alta.), in a press release.
“We wanted to look at that question, as well as a possible link between strep and behavioral symptoms like obsessive-compulsive disorder and attention deficit hyperactivity disorder,” he said.
The researchers followed 715 children with CTD (mean age 10.7 years, 76.8% male) who were drawn from 16 specialist clinics in nine countries. Almost all (90.8%) had a diagnosis of Tourette syndrome (TS); 31.7% had OCD, and 36.1% had ADHD.
Participants received a throat swab at baseline, and of these, 8.4% tested positive for GAS.
Participants were evaluated over a 16- to 18-month period, consisting of:
- Face-to-face interviews and collection of throat swabs and serum at 4-month intervals.
- Telephone interviews at 4-month intervals, which took place at 2 months between study visit.
- Weekly diaries: Parents were asked to indicate any worsening of tics and focus on detecting the earliest possible tic exacerbation.
Beyond the regularly scheduled visits, parents were instructed to report, by phone or email, any noticeable increase in tic severity and then attend an in-person visit.
Tic exacerbations were defined as an increase of greater than or equal to 6 points on the Yale Global Tic Severity Scale-Total Tic Severity Score (YGTSS-TTS), compared with the previous assessment.
OCD and ADHD symptoms were assessed according to the Yale-Brown Obsessive-Compulsive Scale and the parent-reported Swanson, Nolan, and Pelham-IV (SNAP-IV) questionnaire.
The researchers divided GAS exposures into four categories: new definite exposure; new possible exposure; ongoing definite exposure; and ongoing possible exposure.
Unlikely trigger
During the follow-up period, 43.1% (n = 308) of participants experienced tic exacerbations. Of these, 218 participants experienced one exacerbation, while 90 participants experienced two, three, or four exacerbations.
The researchers did not find a significant association between GAS exposure status and tic exacerbation.
Participants who did develop a GAS-associated exacerbation (n = 49) were younger at study exit (9.63 vs. 11.4 years, P < .0001) and were more likely to be male (46/49 vs. 210/259, Fisher’s = .035), compared with participants who developed a non-GAS-associated tic exacerbation (n = 259).
Additional analyses were adjusted for sex, age at onset, exposure to psychotropic medications, exposures to antibiotics, geographical regions, and number of visits in the time interval of interest. These analyses continued to yield no significant association between new or ongoing concurrent GAS exposure episodes and tic exacerbation events.
Of the children in the study, 103 had a positive throat swab, indicating a new definite GAS exposure, whereas 46 had a positive throat swab indicating an ongoing definite exposure (n = 149 visits). Of these visits, only 20 corresponded to tic exacerbations.
There was also no association between GAS exposure and OCD symptom severity. However, it was associated with longitudinal changes (between 17% and 21%, depending on GAS exposure definition) in the severity of hyperactivity-impulsivity symptoms in children with ADHD.
“It is known that immune activation may concur with tic severity in youth with CTDs and that psychosocial stress levels may predict short-term future tic severity in these patients,” the authors write.
“Our findings suggest that GAS is unlikely to be the main trigger for immune activation in these patients,” they add.
Brick or cornerstone?
Commenting on the study for this news organization, Margo Thienemann, MD, clinical professor of psychiatry, Stanford (Calif.) University, said that in the clinic population they treat, GAS, other pathogens, and other stresses can “each be associated with PANS symptom exacerbations.”
However, these “would not be likely to cause PANS symptoms exacerbations in the vast majority of individuals, only individuals with genetic backgrounds and immunologic dysfunctions creating susceptibility,” said Dr. Thienemann, who also directs the Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) Clinic at Stanford Children’s Health. She was not involved with the study.
In an accompanying editorial, Andrea Cavanna, MD, PhD, honorary reader in neuropsychiatry, Birmingham (England) Medical School and Keith Coffman, MD, director, Tourette Syndrome Center of Excellence, Children’s Mercy Hospital, Kansas City, Mo., suggest that perhaps the “interaction of psychosocial stress and GAS infections contributes more to tic exacerbation than psychosocial stress alone.”
“Time will tell whether this study stands as another brick – a cornerstone? – in the wall that separates streptococcus from tics,” they write.
The study was supported by the European Union’s Seventh Framework Program. Dr. Martino has received honoraria for lecturing from the Movement Disorders Society, Tourette Syndrome Association of America, and Dystonia Medical Research Foundation Canada; research funding support from Dystonia Medical Research Foundation Canada, the University of Calgary (Alta.), the Michael P.

There was also no association between GAS exposure and OCD symptom severity. However, it was associated with longitudinal changes (between 17% and 21%, depending on GAS exposure definition) in the severity of hyperactivity-impulsivity symptoms in children with ADHD.
“It is known that immune activation may concur with tic severity in youth with CTDs and that psychosocial stress levels may predict short-term future tic severity in these patients,” the authors write.
“Our findings suggest that GAS is unlikely to be the main trigger for immune activation in these patients,” they add.
Brick or cornerstone?
Commenting on the study for this news organization, Margo Thienemann, MD, clinical professor of psychiatry, Stanford (Calif.) University, said that in the clinic population they treat, GAS, other pathogens, and other stresses can “each be associated with PANS symptom exacerbations.”
However, these “would not be likely to cause PANS symptoms exacerbations in the vast majority of individuals, only individuals with genetic backgrounds and immunologic dysfunctions creating susceptibility,” said Dr. Thienemann, who also directs the Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) Clinic at Stanford Children’s Health. She was not involved with the study.
In an accompanying editorial, Andrea Cavanna, MD, PhD, honorary reader in neuropsychiatry, Birmingham (England) Medical School and Keith Coffman, MD, director, Tourette Syndrome Center of Excellence, Children’s Mercy Hospital, Kansas City, Mo., suggest that perhaps the “interaction of psychosocial stress and GAS infections contributes more to tic exacerbation than psychosocial stress alone.”
“Time will tell whether this study stands as another brick – a cornerstone? – in the wall that separates streptococcus from tics,” they write.

Exposure to Group A streptococcus (GAS) does not appear to worsen symptoms of Tourette syndrome and other chronic tic disorders (CTDs) in children and adolescents, new research suggests.
Investigators studied over 700 children and teenagers with CTDs, one-third of whom also had attention deficit hyperactivity disorder and one-third who had obsessive-compulsive disorder (OCD).
The youngsters were followed for an average of 16 months and evaluated at 4-month intervals to see if they were infected with GAS. Tic severity was monitored through telephone interviews, in-person visits, and parental reports.
A little less than half the children experienced worsening of tics during the study period, but the researchers found no association between these exacerbations and GAS exposure.
There was also no link between GAS and worsening OCD. However, researchers did find an association between GAS exposure and an increase in hyperactivity and impulsivity in patients with ADHD.
“This study does not support GAS exposures as contributing factors for tic exacerbations in children with CTD,” the authors note.
“Specific work-up or active management of GAS infections is unlikely to help modifying the course of tics in CTD and is therefore not recommended,” they conclude.
The study was published online in Neurology.
‘Intense debate’
The association between GAS and CTD stems from the description of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection (PANDAS) – a condition that is now incorporated in the pediatric acute neuropsychiatric syndromes (PANS), the authors note. Tics constitute an “accompanying feature” of this condition.
However, neither population-based nor longitudinal clinical studies “could definitely establish if tic exacerbations in CTD are associated with GAS infections,” they note.
“The link between streptococcus and tics in children is still a matter of intense debate,” said study author Davide Martino, MD, PhD, director of the Movement Disorders Program at the University of Calgary (Alta.), in a press release.
“We wanted to look at that question, as well as a possible link between strep and behavioral symptoms like obsessive-compulsive disorder and attention deficit hyperactivity disorder,” he said.
The researchers followed 715 children with CTD (mean age 10.7 years, 76.8% male) who were drawn from 16 specialist clinics in nine countries. Almost all (90.8%) had a diagnosis of Tourette syndrome (TS); 31.7% had OCD, and 36.1% had ADHD.
Participants received a throat swab at baseline, and of these, 8.4% tested positive for GAS.
Participants were evaluated over a 16- to 18-month period, consisting of:
- Face-to-face interviews and collection of throat swabs and serum at 4-month intervals.
- Telephone interviews at 4-month intervals, which took place at 2 months between study visit.
- Weekly diaries: Parents were asked to indicate any worsening of tics and focus on detecting the earliest possible tic exacerbation.
Beyond the regularly scheduled visits, parents were instructed to report, by phone or email, any noticeable increase in tic severity and then attend an in-person visit.
Tic exacerbations were defined as an increase of greater than or equal to 6 points on the Yale Global Tic Severity Scale-Total Tic Severity Score (YGTSS-TTS), compared with the previous assessment.
OCD and ADHD symptoms were assessed according to the Yale-Brown Obsessive-Compulsive Scale and the parent-reported Swanson, Nolan, and Pelham-IV (SNAP-IV) questionnaire.
The researchers divided GAS exposures into four categories: new definite exposure; new possible exposure; ongoing definite exposure; and ongoing possible exposure.
Unlikely trigger
During the follow-up period, 43.1% (n = 308) of participants experienced tic exacerbations. Of these, 218 participants experienced one exacerbation, while 90 participants experienced two, three, or four exacerbations.
The researchers did not find a significant association between GAS exposure status and tic exacerbation.
Participants who did develop a GAS-associated exacerbation (n = 49) were younger at study exit (9.63 vs. 11.4 years, P < .0001) and were more likely to be male (46/49 vs. 210/259, Fisher’s = .035), compared with participants who developed a non-GAS-associated tic exacerbation (n = 259).
Additional analyses were adjusted for sex, age at onset, exposure to psychotropic medications, exposures to antibiotics, geographical regions, and number of visits in the time interval of interest. These analyses continued to yield no significant association between new or ongoing concurrent GAS exposure episodes and tic exacerbation events.
Of the children in the study, 103 had a positive throat swab, indicating a new definite GAS exposure, whereas 46 had a positive throat swab indicating an ongoing definite exposure (n = 149 visits). Of these visits, only 20 corresponded to tic exacerbations.
There was also no association between GAS exposure and OCD symptom severity. However, it was associated with longitudinal changes (between 17% and 21%, depending on GAS exposure definition) in the severity of hyperactivity-impulsivity symptoms in children with ADHD.
“It is known that immune activation may concur with tic severity in youth with CTDs and that psychosocial stress levels may predict short-term future tic severity in these patients,” the authors write.

7 key changes: The 2021 child and adolescent immunization schedules
Each February, the Centers for Disease Control and Prevention, along with multiple professional organizations, releases an updated Recommended Child and Adolescent Immunization Schedule.
Recent years have seen fewer changes in the vaccine schedule, mostly with adjustments based on products coming on or off the market, and sometimes with slight changes in recommendations. This year is no different, with mostly minor changes in store. As most practitioners know, having quick access to the tables that accompany the recommendations is always handy. Table 1 contains the typical, recommended immunization schedule. Table 2 contains the catch-up provisions, and Table 3 provides guidance on vaccines for special circumstances and for children with specific medical conditions.
2021 childhood and adolescent immunization schedule
One update is a recommendation that patients with egg allergies who had symptoms more extensive than hives should receive the influenza vaccine in a medical setting where severe allergic reactions or anaphylaxis can be recognized and treated, with the exclusion of two specific preparations, Flublok and Flucelvax.
In regard to the live attenuated influenza vaccine (LAIV), there are several points of reinforcement. First, the nomenclature has generally been changed to “LAIV4” throughout the document because only quadrivalent preparations are available. There are specific recommendations that patients should not receive LAIV4 if they recently took antiviral medication for influenza, with “lockout” periods lasting from 2 days to 17 days, depending on the antiviral preparation used. In addition, there is an emphasis on not using LAIV4 for children younger than 2 years.
Two updates to the meningococcal group B vaccine are worth reviewing. The first is that children aged 10 years or older with complement deficiency, complement inhibitor use, or asplenia should receive a meningitis B booster dose beginning 1 year after completion of the primary series, with boosters thereafter every 2 or 3 years as long as that patient remains at greater risk. Another recommendation for patients 10 years or older is that, even if they have received a primary series of meningitis B vaccines, they should receive a booster dose in the setting of an outbreak if it has been 1 year or more since completion of their primary series.
Recommendations have generally been relaxed for tetanus prophylaxis in older children, indicating that individuals requiring tetanus prophylaxis or their 10-year tetanus booster after receipt of at least one Tdap vaccine can receive either tetanus-diphtheria toxoid or Tdap.
COVID-19 vaccines
Although childhood vaccination against COVID-19 is still currently limited to adolescents involved in clinical trials, pediatricians surely are getting peppered with questions from parents about whether they should be vaccinated and what to make of the recent reports about allergic reactions. Fortunately, there are several resources for pediatricians. First, two reports point out that true anaphylactic reactions to COVID-19 vaccines appear quite rare. The reported data on Pfizer-developed mRNA vaccine demonstrated an anaphylaxis rate of approximately 2 cases per 1 million doses administered. Among the 21 recipients who experienced anaphylaxis (out of over 11 million total doses administered), fully one third had a history of anaphylaxis episodes. The report also reviews vaccine reactions that were reported but were not classified as anaphylaxis, pointing out that when reporting vaccine reactions, we should be very careful in the nomenclature we use.
Reporting on the Moderna mRNA vaccine showed anaphylaxis rates of about 2.5 per 1 million doses, with 50% of the recipients who experienced true anaphylaxis having a history of anaphylaxis. Most of those who experienced anaphylaxis (90% in the Moderna group and 86% in the Pfizer group) exhibited symptoms of anaphylaxis within 30 minutes of receiving the vaccine. The take-home point, and the current CDC recommendation, is that many individuals, even those with a history of anaphylaxis, can still receive COVID-19 vaccines. The rates of observed anaphylaxis after COVID vaccination are far below population rates of a history of allergy or severe allergic reactions. When coupled with an estimated mortality rate of 0.5%-1% for SARS-CoV-2 disease, that CDC recommends that we encourage people, even those with severe allergies, to get vaccinated.
One clear caveat is that individuals with a history of severe anaphylaxis, and even those concerned about allergies, should be observed for a longer period after vaccination (at least 30 minutes) than the 15 minutes recommended for the general population. In addition, individuals with a specific anaphylactic reaction or severe allergic reaction to any injectable vaccine should confer with an immunologist before considering vaccination.
Another useful resource is a column published by the American Medical Association that walks through some talking points for providers when discussing whether a patient should receive COVID-19 vaccination. Advice is offered on answering patient questions about which preparation to get, what side effects to watch for, and how to report an adverse reaction. Providers are reminded to urge patients to complete whichever series they begin (get that second dose!), and that they currently should not have to pay for a vaccine. FAQ resource pages are available for patients and health care providers.
More vaccine news: HPV and influenza
Meanwhile, published vaccine reports provide evidence from the field to demonstrate the benefits of vaccination. A study published in the New England Journal of Medicine reported on the effectiveness of human papillomavirus (HPV) vaccine in a Swedish cohort. The report evaluated females aged between 10 and 30 years beginning in 2006 and followed them through 2017, comparing rates of invasive cervical cancer among the group who received one or more HPV vaccine doses with the group who receive none. Even without adjustment, the raw rate of invasive cervical cancer in the vaccinated group was half of that in the unvaccinated group. After full adjustment, some populations experienced incident rate ratios that were greater than 80% reduced. The largest reduction, and therefore the biggest benefit, was among those who received the HPV vaccine before age 17.
A report from the United States looking at the 2018-2019 influenza season demonstrated a vaccine effectiveness rate against hospitalization of 41% and 51% against any ED visit related to influenza. The authors note that there was considerable drift in the influenza A type that appeared late in the influenza season, reducing the overall effectiveness, but that the vaccine was still largely effective.

New cases of child COVID-19 drop for fifth straight week
The fifth consecutive week with a decline has the number of new COVID-19 cases in children at its lowest level since late October, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.
, when 61,000 cases were reported, the AAP and CHA said in their weekly COVID-19 report.
The cumulative number of COVID-19 cases in children is now just over 3.1 million, which represents 13.1% of cases among all ages in the United States, based on data gathered from the health departments of 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.
More children in California (439,000) have been infected than in any other state, while Illinois (176,000), Florida (145,000), Tennessee (137,000), Arizona (127,000), Ohio (121,000), and Pennsylvania (111,000) are the only other states with more than 100,000 cases, the AAP/CHA report shows.
Proportionally, the children of Wyoming have been hardest hit: Pediatric cases represent 19.4% of all cases in the state. The other four states with proportions of 18% or more are Alaska, Vermont, South Carolina, and Tennessee. Cumulative rates, however, tell a somewhat different story, as North Dakota leads with just over 8,500 cases per 100,000 children, followed by Tennessee (7,700 per 100,000) and Rhode Island (7,000 per 100,000), the AAP and CHA said.
Deaths in children, which had not been following the trend of fewer new cases over the last few weeks, dropped below double digits for the first time in a month. The six deaths that occurred during the week of Feb. 12-18 bring the total to 247 since the start of the pandemic in the 43 states, along with New York City and Guam, that are reporting such data, according to the report.

Oxford launches COVID-19 vaccine study in children
Oxford University is starting a COVID-19 vaccine study with children and young adults aged between 6 and 17 years.
At Oxford and three partner sites in London, Southampton, and Bristol, the phase 2 clinical trial will test whether kids and teens have a good immune response to the AstraZeneca vaccine. Previous trials have shown that the shot is safe in children.
“While most children are relatively unaffected by coronavirus and are unlikely to become unwell with the infection, it is important to establish the safety and immune response to the vaccine in children and young people as some children may benefit from vaccination,” Andrew Pollard, PhD, the chief investigator for the trial and a professor of pediatric infection and immunity at Oxford, said in a statement.
The new trial will enroll 300 volunteers, with up to 240 receiving the vaccine. The control group will receive a meningitis vaccine, which is safe in children and produces similar side effects to the COVID-19 vaccine, such as a sore arm.
COVID-19 vaccine trials have included children over age 12, so this marks the youngest group to be tested so far. Pfizer, Moderna, and Janssen have announced plans to start trials in younger children this spring, according to the Washington Post. Widespread vaccination in children likely won’t occur until 2022, the newspaper reported.
The trial launched on Feb. 12, and the first vaccinations are expected by the end of the month. Parents can visit Oxford’s COVID-19 Vaccine Trial website to sign their children up for the study.
“This study will play an important role in helping to protect children in the future,” Grace Li, a pediatric clinical research fellow for the Oxford Vaccine Group, said in the statement.
“We’ve already seen that the vaccine is safe and effective in adults, and our understanding of how children are affected by the coronavirus continues to evolve,” she said.

Hospitalizations for food anaphylaxis triple, but deaths down in United Kingdom
The rate of hospital admissions in the United Kingdom for food-induced anaphylaxis more than tripled over the 20 years from 1998 to 2018, but the case fatality rate fell by more than half, researchers report in BMJ.
“Cow’s milk is increasingly identified as the culprit allergen for fatal food reactions and is now the commonest cause of fatal anaphylaxis in children,” write Alessia Baseggio Conrado, PhD, a biochemist with the National Heart and Lung Institute at Imperial College London, and colleagues. “More education is needed to highlight the specific risks posed by cow’s milk to people who are allergic to increase awareness among food businesses.”
Whereas recognition of the risks posed by nut allergies has increased, people think milk allergy is mild, says senior author Paul. J. Turner, BMBCh, PhD, an allergist/immunologist at Imperial College. “This is often true in very young children, but school-aged children who still have milk allergy tend to have a more allergic profile, often with other allergies, including asthma,” Dr. Turner told this news organization. “Also, milk is very common in our diet, and you don’t need much milk to achieve a decent dose of allergen.”
During the study period, 101,891 people were hospitalized for anaphylaxis; 30,700 cases (30%) were coded as having been triggered by food.
These food-related admissions represent an increase from 1.23 to 4.04 per 100,000 population per year, for an annual increase of 5.7% (95% confidence interval, 5.5-5.9; P < .001), the authors write.
The largest jump occurred among children younger than 15 years, for whom admissions rose from 2.1 to 9.2 per 100,000 population per year, an annual increase of 6.6% (95% CI, 6.3-7.0). The annual increases were 5.9% (95% CI, 5.6-6.2) among persons aged 15 to 59 years and 2.1% (95% CI, 1.8-3.1) among those aged 60 years and older.
The investigators used data from England, Scotland, Wales, and Northern Ireland to track temporal trends and age and sex distributions for hospital admissions for which the primary diagnosis was anaphylaxis attributable to both food and nonfood triggers. These data were compared with nationally reported fatalities.
Over the 20-year period, 152 deaths were attributed to likely food-induced anaphylaxis. During that time, the case fatality rate for confirmed fatal food anaphylaxis fell from 0.7% to 0.19% (rate ratio, 0.931; 95% CI, 0.904-0.959; P < .001) and declined to 0.30% for suspected fatal food anaphylaxis (rate ratio, 0.970; 95% CI, 0.945-0.996; P = .024).
Between 1992 and 2018, at least 46% of all anaphylactic fatalities were deemed to be triggered by peanut or tree nut. Among school-aged children, 26% of anaphylactic fatalities were attributed to cow’s milk.
Not surprisingly, during the study period, there was an increase of 336% in prescriptions for adrenaline autoinjectors. Such prescriptions increased 11% per year.
Global trend
The data extend findings Dr. Turner and colleagues reported for England and Wales in 2014 regarding the entire United Kingdom population and align with epidemiologic trends in hospital admissions for anaphylaxis in the United States and Australia.
The researchers say better recognition and management of anaphylaxis could partly explain the decrease in fatalities, but the rise in hospitalizations remains puzzling. “Whether a true increase in the prevalence of anaphylaxis has occurred (rather than a reduction in the threshold to admit patients presenting with anaphylaxis) is unclear because evidence is lacking for an increase in prevalence of food allergy in the [United Kingdom] (and elsewhere) over the same time period,” they write.
Ronna L. Campbell, MD, PhD, an emergency physician at the Mayo Clinic in Rochester, Minn., has noted similar trends in the United States. “It may be that anaphylaxis recognition and diagnosis have improved, resulting in earlier administration of epinephrine,” Dr. Campbell said in an interview. “So while cases are increasing, earlier recognition and treatment result in decreased fatalities.” She is unaware of any new guidelines recommending increased hospitalization that would explain the puzzling rise in admissions.
According to the study authors, the clinical criteria used to diagnose anaphylaxis in the United Kingdom did not change during the study period. Although national guidance recommending the hospitalization of children younger than 16 who are suspected of having anaphylaxis was introduced in 2011 and may have boosted admissions, the year-on-year rate of increase has persisted since 2014. “Therefore the increase over the past 5 years cannot be attributed to the impact of the guidance,” they write.
The study was funded by grants from the U.K. Medical Research Council and U.K. Food Standards Agency. Two coauthors have disclosed financial relationships with industry outside of the submitted work. Dr. Conrado has disclosed no relevant financial relationships.

ASDSA warns of rogue insulin pen use for DIY fillers
.
In the safety warning, issued on Feb. 18, the ASDSA reported that ASDSA members, all board-certified dermatologists, have seen evidence online of young people using so-called “hyaluron pens” to inject hyaluronic acid filler in the epidermal and upper dermal skin.
The pens being used and promoted in social media for do-it-yourself filler injections are medical devices originally developed for insulin injections. “The use of air pressure technology causes these pens to deliver the hyaluronic acid to insert nanoscale molecules of the filler through the skin,” according to the ASDSA statement. Marketing materials state that the pens can be used to create volume and shape in the lips, and to improve the appearance of nasolabial lines, marionette lines, brow lines known as “elevens,” and forehead wrinkles. Claims that the hyaluronic acid only reaches the papillary layer of the dermis, and is therefore safe, do not alleviate the risk of injury in inexperienced hands, the ASDSA statement points out.
“We are concerned about California children falling prey to products that are not appropriate and safe for them to use,” Elan Newland, MD, member of the ASDSA and the California Society for Dermatology and Dermatological Surgery (CalDerm), said in the statement. “The power of social media is very strong, especially for impressionable teenagers. CalDerm supports alerting consumers and regulators of the dangers of these pens,” he said.
“TikTok is proving to be an extremely powerful platform to communicate, entertain, and even educate, which is why many physicians are getting involved and finding success there. Unfortunately, just like the World Wide Web, there is misinformation there and even dangerous lies,” Sandra Lee, MD, who practices in Upland, Calif. (and is also known as “Dr. Pimple Popper”), said in the statement.
“It’s very concerning to see young people posting a How To on injecting their own lips with hyaluronic acid serum using an ‘airgun’ pen, which acts much like a BB gun to push with force the product under the skin,” she added. “So many things can go wrong.”
The ASDSA has contacted the Food and Drug Administration to report these safety concerns. “In addition, the ASDSA is alerting state medical and estheticians’ boards regarding these patient safety concerns and alerting consumers directly about the risks through social media and other education materials,” according to the statement.

Emerging research shows link between suicidality, ‘high-potency’ cannabis products
Number of suicides positive for marijuana on rise soared among Colorado youth
In the days since recreational sales of marijuana became legal in Colorado in January 2014, concerning trends have emerged among the state’s young cannabis users.
According to a report from the Rocky Mountain High Intensity Drug Trafficking Area, between 2014 and 2017, the number of suicides positive for marijuana increased 250% among those aged 10-19 years (from 4 to 14) and 22% among those aged 20 and older (from 118 to 144). “Other states are seeing something similar, and there is an emerging research showing a relationship between suicidality and the use of marijuana, especially high-potency products that are available in legalized markets,” Paula D. Riggs, MD, reported during an annual psychopharmacology update held by the Nevada Psychiatric Association.
During that same 3-year time span, the proportion of Colorado youth aged 12 years and older who used marijuana in the past month jumped by 45%, which is more than 85% above the national average. “Similarly, among college-age students, we’ve seen an 18% increase in past-month marijuana use, which is 60% above the national average,” said Dr. Riggs, professor and vice chair of psychiatry at the University of Colorado at Denver, Aurora.
Among adolescents, state health officials have observed a 5% increase in the proportion of those who used marijuana in the past month, which is more than 54% above the national average. “But a concerning trend is that we’re seeing an increase in the use of concentrates such as dabs and waxes,” she said. “That’s worrisome in terms of exposure to high-potency products.”
In other findings, 48% of young marijuana users reported going to work high (40% at least once per week), and there has been a 170% increase in youth ED urgent care visits for marijuana-related illnesses such as cannabinoid hyperemesis syndrome or first-episode psychosis. State health officials have also observed a 148% increase in marijuana-related hospitalizations.
According to Dr. Riggs, who also directs the University of Colorado’s division of addiction science, prevention, and treatment, the average marijuana joint in the 1960s contained about 3% tetrahydrocannabinol (THC), a level that crept up to the 4%-6% range in 2002. In today’s postlegalization era, the average joint now contains 13%-23% THC. “What’s concerning is that the concentrates – the dabs, waxes, shatter, and butane hash oils – contain upward of 70%-95% THC,” Dr. Riggs said. “Those are highly potent products that represent about 25% of the market share now. That’s a very big concern because the higher the potency the cannabis product used, the greater the abuse liability and addictive potential.”
The use of high-potency products also doubles the risk of developing generalized anxiety disorder, triples the risk of tobacco dependence, doubles the risk of other illicit substance disorders, and it at least quadruples the risk of developing first-episode psychosis in young people. “So, when you’re taking a cannabis use history, it’s important to ask patients about the potency of the products being used,” she said.
In the 2019 Monitoring the Future survey, 12% of U.S. 8th graders self-reported marijuana use in the past year and 7% in the past month, compared with 29% and 18% of 10th graders, respectively. Self-reported use by 12th graders was even more elevated (36% in the past year and 29% in the past month). “The concern is, this survey doesn’t really capture what’s happening with marijuana concentrates,” Dr. Riggs said.
A survey of Colorado youth conducted by the state’s Department of Public Health and Environment found that the percentage of students who reported using concentrated forms of marijuana has risen steadily in recent years and now stands at roughly 34%. “The use of edibles has also crept up,” said Dr. Riggs, who noted that marijuana dispensaries in Colorado outnumber Starbucks locations and McDonald’s restaurants. “You might not think that’s particularly concerning, except that the use of edibles is even more associated with onset of psychosis than other forms. This is probably because when you eat a marijuana product, you can’t control the exposure or the dose that you’re ingesting. We need to be concerned about these trends.”
European studies report that 30%-50% of new cases of first-onset psychosis are attributed to high-potency cannabis. “There is a dose-response relationship between cannabis and psychosis,” Dr. Riggs said. “That is, the frequency and duration of cannabis use, or the use of high-potency products, and the age of onset, are strongly associated with the risk of first-episode psychosis.
Researchers have known for some time that alterations in the endocannabinoid system are associated with psychosis independent of cannabis exposure. “Dysregulation of that endocannabinoid system occurs in patients at all stages of the psychosis continuum,” she continued. “It also means that the endocannabinoid system is a potential therapeutic target for psychosis.”
According to Dr. Riggs, THC exposure acutely increases dopamine in the ventral striatum and it can produce transient psychotomimetic effects in clinical and nonclinical populations. Genetic differences in the dopaminergic system can also interact with cannabis use to increase the risk of psychosis.
“For example, the COMT (catechol-O-methyltransferase) breaks down catecholamines such as dopamine in the prefrontal cortex,” she explained. “If you have a COMT gene polymorphism, that increases your risk of developing psychosis due to increased levels of dopamine signaling.”
She emphasized the importance of clinicians to understand that the age of cannabis use onset, the duration, frequency, and THC potency is related to the psychosis risk and worse prognosis. The earlier the initiation of marijuana use, the greater potential for first-episode psychosis. “Those who continue using cannabis after a first-episode psychosis have greater severity of psychotic illness and more treatment resistance, and they’re less likely to engage or be compliant with treatment recommendations,” Dr. Riggs said. “So, Because if they resume cannabis use, this can turn into a more chronic psychotic disorder.”
She added that, while insufficient evidence exists to determine whether cannabis plays a causal role in the development of schizophrenia or not, mounting evidence suggests that cannabis use may precipitate earlier onset of schizophrenia in those with other risk factors for the disorder. “There is considerable evidence that cannabis use increases the risk of psychosis in a dose-related manner, especially with an onset before age 16,” Dr. Riggs said. “However, this does not mean that cannabis is safe for young adults. Cannabis-induced psychotic symptoms often develop during young adulthood and may become chronic.”
Dr. Riggs disclosed that she had received grant funding from the National Institute on Drug Abuse. She is also executive director for Encompass, which provides integrated treatment for adolescents and young adults.

According to a report from the Rocky Mountain High Intensity Drug Trafficking Area, between 2014 and 2017, the number of suicides positive for marijuana increased 250% among those aged 10-19 years (from 4 to 14) and 22% among those aged 20 and older (from 118 to 144). “Other states are seeing something similar, and there is an emerging research showing a relationship between suicidality and the use of marijuana, especially high-potency products that are available in legalized markets,” Paula D. Riggs, MD, reported during an annual psychopharmacology update held by the Nevada Psychiatric Association.
During that same 3-year time span, the proportion of Colorado youth aged 12 years and older who used marijuana in the past month jumped by 45%, which is more than 85% above the national average. “Similarly, among college-age students, we’ve seen an 18% increase in past-month marijuana use, which is 60% above the national average,” said Dr. Riggs, professor and vice chair of psychiatry at the University of Colorado at Denver, Aurora.
Among adolescents, state health officials have observed a 5% increase in the proportion of those who used marijuana in the past month, which is more than 54% above the national average. “But a concerning trend is that we’re seeing an increase in the use of concentrates such as dabs and waxes,” she said. “That’s worrisome in terms of exposure to high-potency products.”
In other findings, 48% of young marijuana users reported going to work high (40% at least once per week), and there has been a 170% increase in youth ED urgent care visits for marijuana-related illnesses such as cannabinoid hyperemesis syndrome or first-episode psychosis. State health officials have also observed a 148% increase in marijuana-related hospitalizations.
According to Dr. Riggs, who also directs the University of Colorado’s division of addiction science, prevention, and treatment, the average marijuana joint in the 1960s contained about 3% tetrahydrocannabinol (THC), a level that crept up to the 4%-6% range in 2002. In today’s postlegalization era, the average joint now contains 13%-23% THC. “What’s concerning is that the concentrates – the dabs, waxes, shatter, and butane hash oils – contain upward of 70%-95% THC,” Dr. Riggs said. “Those are highly potent products that represent about 25% of the market share now. That’s a very big concern because the higher the potency the cannabis product used, the greater the abuse liability and addictive potential.”
The use of high-potency products also doubles the risk of developing generalized anxiety disorder, triples the risk of tobacco dependence, doubles the risk of other illicit substance disorders, and it at least quadruples the risk of developing first-episode psychosis in young people. “So, when you’re taking a cannabis use history, it’s important to ask patients about the potency of the products being used,” she said.
In the 2019 Monitoring the Future survey, 12% of U.S. 8th graders self-reported marijuana use in the past year and 7% in the past month, compared with 29% and 18% of 10th graders, respectively. Self-reported use by 12th graders was even more elevated (36% in the past year and 29% in the past month). “The concern is, this survey doesn’t really capture what’s happening with marijuana concentrates,” Dr. Riggs said.
A survey of Colorado youth conducted by the state’s Department of Public Health and Environment found that the percentage of students who reported using concentrated forms of marijuana has risen steadily in recent years and now stands at roughly 34%. “The use of edibles has also crept up,” said Dr. Riggs, who noted that marijuana dispensaries in Colorado outnumber Starbucks locations and McDonald’s restaurants. “You might not think that’s particularly concerning, except that the use of edibles is even more associated with onset of psychosis than other forms. This is probably because when you eat a marijuana product, you can’t control the exposure or the dose that you’re ingesting. We need to be concerned about these trends.”
European studies report that 30%-50% of new cases of first-onset psychosis are attributed to high-potency cannabis. “There is a dose-response relationship between cannabis and psychosis,” Dr. Riggs said. “That is, the frequency and duration of cannabis use, or the use of high-potency products, and the age of onset, are strongly associated with the risk of first-episode psychosis.
Researchers have known for some time that alterations in the endocannabinoid system are associated with psychosis independent of cannabis exposure. “Dysregulation of that endocannabinoid system occurs in patients at all stages of the psychosis continuum,” she continued. “It also means that the endocannabinoid system is a potential therapeutic target for psychosis.”
According to Dr. Riggs, THC exposure acutely increases dopamine in the ventral striatum and it can produce transient psychotomimetic effects in clinical and nonclinical populations. Genetic differences in the dopaminergic system can also interact with cannabis use to increase the risk of psychosis.
“For example, the COMT (catechol-O-methyltransferase) breaks down catecholamines such as dopamine in the prefrontal cortex,” she explained. “If you have a COMT gene polymorphism, that increases your risk of developing psychosis due to increased levels of dopamine signaling.”
She emphasized the importance of clinicians to understand that the age of cannabis use onset, the duration, frequency, and THC potency is related to the psychosis risk and worse prognosis. The earlier the initiation of marijuana use, the greater potential for first-episode psychosis. “Those who continue using cannabis after a first-episode psychosis have greater severity of psychotic illness and more treatment resistance, and they’re less likely to engage or be compliant with treatment recommendations,” Dr. Riggs said. “So, Because if they resume cannabis use, this can turn into a more chronic psychotic disorder.”
She added that, while insufficient evidence exists to determine whether cannabis plays a causal role in the development of schizophrenia or not, mounting evidence suggests that cannabis use may precipitate earlier onset of schizophrenia in those with other risk factors for the disorder. “There is considerable evidence that cannabis use increases the risk of psychosis in a dose-related manner, especially with an onset before age 16,” Dr. Riggs said. “However, this does not mean that cannabis is safe for young adults. Cannabis-induced psychotic symptoms often develop during young adulthood and may become chronic.”
Dr. Riggs disclosed that she had received grant funding from the National Institute on Drug Abuse. She is also executive director for Encompass, which provides integrated treatment for adolescents and young adults.

Make the Diagnosis - March 2021
Because of the lack of improvement with topical corticosteroids, a skin biopsy was performed from a lesion on the lower back which showed an epidermis with compact hyperkeratosis and a thickened granular layer. Within the dermis, there was a lichenoid infiltrate of lymphocytes with a prominent interface change and rare dyskeratotic keratinocytes consistent with lichen planus.
Lichen planus is an inflammatory condition of the skin seen mainly in the adult population and is rare in children. This condition affects 0.5%-1% of the population, with maybe a higher prevalence in woman with no racial predilection in the adult or pediatric population. Most patients diagnosed are described to be over 40 years of age, but in children, the mean age for presentation is reported between the ages of 7 and 11.8 years.1 Interestingly, most of the published larger studies of lichen planus in children originate from India. In a U.K. study, about 80% of the cases reported were from children of Indian descent, as is our patient; so it is possible that lichen planus may be more prevalent in India.1 In a study based in the United States, cases were more prevalent in African American children.2
The exact cause of this condition is not known but studies have suggested that activated T cells, particularly CD8+, attack and cause apoptosis of the basal keratinocytes.3 There appears to be an up-regulation of Th1 cytokines such as interferon‐gamma, tumor necrosis factor–alpha, interleukin‐1 alpha, IL‐6, and IL‐8, as well as other apoptosis-related molecules.3
Lichen planus has been associated with other systemic conditions especially liver disease (chronic active hepatitis C and primary biliary cirrhosis). Children and adults may also have coexistence of other autoimmune diseases such as autoimmune polyendocrinopathy, myasthenia gravis, autoimmune thyroid disease, vitiligo, and thymoma. Some reports have also found a higher prevalence of atopic dermatitis in children with lichen planus.4
The lesions are typically described as the four “Ps” for pruritic, polygonal, purpuric flat-topped papules, and plaques. The papules of lichen planus have characteristically dry fine white streaks known as Wickham’s striae. The lesions can occur anywhere on the body, but they tend to occur more commonly on the flexures of the forearms, the wrists, ankles, shins, knees, and the torso. The face is rarely affected. In some patients oral, scalp (lichen planopilaris), nails, and rarely conjunctival, genital, and esophageal involvement can occur.2
In histopathology, the lesions are characterized by a wedge-shaped hypergranulosis, marked hyperkeratosis, and irregular sawtooth-like acanthosis of rete ridges on the epidermis. The dermal-epidermal junction typically shows an interstitial dermatitis. Civatte bodies may also be seen. On direct immunofluorescence, IgM-staining of the cytoid bodies in the dermal papilla or peribasilar areas are suggestive of lichen planus.1
The differential diagnosis of lichen planus includes severe lichenified atopic dermatitis, drug-induced lichen planus, graft-versus-host disease, psoriasis, pityriasis rosea, subacute cutaneous lupus, discoid lupus, secondary syphilis, and lichen simplex chronicus. Interestingly, our patient presented with lesions that were not pruritic and more generalized. Compared with eczema, were flexures are commonly affected, our patient’s lesions were localized to the ankles, wrists, extensor knees, and elbows, and no pruritus was reported. Lichenification of skin lesions occurs as a response to chronic scratching as it occurs in atopic dermatitis and lichen simplex chronicus, was considered in our patient, but the lack of pruritus and the more acute presentation made it unlikely.
Lichen planus is considered a self-limiting disease, so treatment is focused on the control of pruritus and to accelerate resolution. The first-line therapy for classic cutaneous lichen planus is the use of potent or superpotent topical corticosteroids for localized disease on the body and extremities and mild to mid-potency for intertriginous areas and the face. Clinical response should be assessed after 2-3 weeks of treatment. For patients with more generalized or recalcitrant disease like our patient, other treatment modalities like phototherapy (narrow-band UVB), a 4- to 6-week course of oral glucocorticoids, or acitretin may be considered. Our patient recently started narrow-band UVB. Other medications that have been reported beneficial for more severe cases include methotrexate, cyclosporine, griseofulvin, hydroxychloroquine, metronidazole, dapsone, and mycophenolate. Recent studies in the adult population have shown apremilast, a phosphodiesterase inhibitor, to be a promising medication for patients with cutaneous lichen planus, though this medication has not been approved yet for use in the pediatric population.5

There was no prior personal or family history of atopic dermatitis or psoriasis. He has no other medical conditions and is not taking any medications.
He denied any joint pain, sun sensitivity, mouth sores, or other symptoms. After the initial consultation he was treated with fluocinonide 0.05% ointment for 2 weeks with slight improvement on the lesions.
On physical exam he presented with hyperpigmented and violaceous lichenified papules and plaques on the extremities and the torso. (photos 1 and 2). He also had hyperpigmented violaceous macules on the eyelids and around the mouth (photos 1 and 2).
