A new, augmented autism-screening strategy boosted the number of boys diagnosed with the condition, especially Spanish speakers, a new study finds. The research was published in JAMA Pediatrics

The number of diagnoses in girls didn’t budge significantly, however, surprising researchers. Still, the findings suggest that “multistage screening and appropriate access to diagnostic services can really move the needle on the early detection of autism and reducing disparities in autism diagnosis and detection,” said lead author R. Christopher Sheldrick, PhD, a Boston University research associate professor of health law, policy, and management, in an interview.

While early intervention is considered crucial, U.S. research suggests that several groups of children – the poor, racial and ethnic minorities, and non-English speakers – are more likely to be diagnosed with autism spectrum disorder (ASD) later in life. “They have much lower access to appropriate services, both to get kids diagnosed and to get the kinds of interventions that can be helpful for families,” Dr. Sheldrick said. “Our study is about trying to close the gap around diagnosis, the first step.”

For the new study, the researchers implemented an intervention strategy in Massachusetts at three Early Intervention (EI) programs, which provide autism screening to children who are referred by pediatricians or parents. The researchers then tracked the programs, all in Boston, and nine comparison programs from the greater Boston area from 2012 to 2018.

Overall, 33,326 children were assessed, all aged 14-36 months. Those at the intervention programs were chosen because they had high levels of poverty. Children at those programs were more likely to be Black than those at the comparison programs (30.7% vs. 12.2%), to be Spanish speakers (28.9% vs. 12.5%), and to be in the lowest household income bracket (66.9% vs. 54.2%). In both groups, about 64% of the children were male.

The intervention strategy aimed to reduce the reliance on screening tests. Instead, the study authors write, “our protocol emphasizes ASD screening as a process that includes clinician and parent decision-making.”

As Dr. Sheldrick explained, parents and specialists observe children together “and then decide whether it’s worth taking the next step, which is a full diagnostic assessment with a licensed professional.” According to the study, either the parent(s) or the specialists could make the referral for a full, university-based assessment.

The goal was to help specialists use their professional judgment more, he said, and refer children who don’t show signs of ASD via a screening instrument but still spark concern, he said. “We’re really trying to create a system in which the screening tools support professional judgment, but don’t really replace it.”

After weighting, the researchers found that diagnoses of ASD were more common in the intervention sites vs. comparison sites (incidence rate ratio, 1.6; 95% confidence interval, 1.3-2.1, P < .001), accounting for an extra 8.1 diagnoses per 1,000 per quarter. Among Spanish-speaking families only, diagnoses grew even more in the intervention sites vs. comparison sites (IRR, 2.6; 95% CI, 1.6-4.3; P < .001), representing 15.4 additional diagnoses per 1,000 children per quarter.

There was also an increase in diagnoses among boys in the intervention sites vs. comparison sites (IRR, 1.8; 95% CI, 1.4-2.3; P < .001), accounting for 14.8 additional diagnoses per 1,000 children per quarter. However, there was no statistically significant increase in diagnosis among girls (IRR, 1.1; 95% CI, 0.6-1.7; P = .84).

The finding about girls surprised the researchers. “The program was highly effective for boys, but really didn’t have any effect for girls,” Dr. Sheldrick said. “Even though autism is considered to be more common in boys, there are questions about whether it’s underidentified in girls. These data would be consistent with that view. So there’s work to do to be able to recognize how a young girl with autism might present and how you might note that in a sensitive way and then respond appropriately.”

The overall message of the study is “that screening with appropriate supports can make a difference,” he said. However, he acknowledged that the extra cost of the program is unclear. “We did not systematically collect data on cost,” he said, noting that the funding for the study paid for both the intervention and the analysis.

For now, he said, researchers are following the children in the study to see if they were able to access treatment services. Some of the investigators are also taking part in a randomized study to evaluate an intervention in children with social communication disorders, he said.

In an accompanying commentary, three pediatric specialists noted that the study is the first to analyze ASD screening in EI. “This study supports the notion of ASD screening as an iterative, multistep process that optimally involves multiple community stakeholders with varying levels of developmental expertise who have done the work to build trust with families,” write pediatrician Kate E. Wallis, MD, MPH, of Children’s Hospital of Philadelphia, graduate student Monica M. Abdul-Chani, MA, of the University of Alabama at Birmingham, and pediatrician Katharine E. Zuckerman, MD, MPH, of Oregon Health & Science University, Portland.

In regard to disparities in diagnosis in Spanish-speaking families, the commentary authors write that “locating a greater proportion of the ASD identification process in EI, which families are already familiar with, has no to low cost for families, and is likely geographically closer for families, can reduce structural barriers to identification.”

They add that the emphasis within Latino families on the “building of warm and caring relationships with others based on mutual trust and respect” can allow EI specialists to “develop relationships with families who may be afraid or skeptical of sharing what could be considered personal details of their family life.”

The commentary authors also note that “it remains all too common for language delays to be attributed to child exposure to two languages, even though data do not support this attribution. Bilingual EI staff can help to demystify this perpetual myth and better estimate a child’s communication and social skills in both languages as they communicate and play.”

Hospital admissions of U.S. children younger than 5 – the only group ineligible for vaccination – have reached their peak since the start of the pandemic, according to new data from the Centers for Disease Control and Prevention.

CDC Director Rochelle Walensky, MD, said the higher numbers show the importance of vaccination for all eligible groups.

“This is the highest number of pediatric hospitalizations we’ve seen throughout the pandemic, which we said about Delta until now,” she said at a CDC briefing Friday. “This very well may be that there are just more cases out there, and our children are more vulnerable when they have more cases surrounding them.”

Despite the skyrocketing admissions, hospitalizations are still relatively low for children, she said. The hospitalization rate for children under 5 is 4 in 100,000, and it’s about 1 in 100,000 in children 5-17.

Dr. Walensky said not all children are being hospitalized for COVID-19 – some are admitted for unrelated issues and test positive but don’t have symptoms.

“We are still learning more about the severity of Omicron in children,” she said, noting that just over 50% of children 12-18 are fully vaccinated, while only 16% of those ages 5-11 are fully vaccinated.

Friday’s teleconference was the first CDC briefing in several months and comes on the heels of recent guideline updates for testing and isolation that have left the American public dumbfounded. When asked why the briefing was held, Dr. Walensky said there had been interest in hearing more from the CDC, saying, “I anticipate this will be the first of many briefings.”

She also defended the confusing guideline changes, saying, “We’re in an unprecedented time with the speed of Omicron cases rising. … This is hard, and I am committed to continuing to improve as we learn more about the science and communicate that to you.”

Antibiotic prescribing in pediatric primary care decreased dramatically when the COVID-19 pandemic hit, and new research indicates that drop was sustained through June of 2021.

Lauren Dutcher, MD, with the division of infectious diseases at Hospital of the University of Pennsylvania in Philadelphia, led a study of 27 pediatric primary care practices in the United States. Encounters from Jan. 1, 2018, through June 30, 2021, were included.

Researchers found a 72.7% drop in antibiotic prescriptions when they compared prepandemic April 2019 through December 2019 with the same period in 2020.

Prescriptions remained at the lower levels, primarily driven by reductions in respiratory tract infection (RTI) encounters, and began to rise only in April of 2021, the authors write.

Findings were published online Jan. 11 in Pediatrics.

Researchers report there were 69,327 antibiotic prescriptions from April through December in 2019 and 18,935 antibiotic prescriptions during the same months in 2020.

“The reduction in prescriptions at visits for respiratory tract infection (RTI) accounted for 87.3% of this decrease,” the authors write.

Both prescribing and acute non–COVID-19 respiratory tract infection diagnoses decreased.

Researchers conclude reductions in viral RTI transmission likely played a large role in reduced RTI pediatric visits and antibiotic prescriptions.

Dr. Dutcher told this publication the reduction was likely caused by a combination of less viral transmission of respiratory infections, helped in part by masking and distancing, but also avoidance of health care in the pandemic.

She said the data reinforce the need for appropriate prescribing.

“Antibiotic prescribing is really heavily driven by respiratory infections so this should continue to clue providers in on how frequently that can be unnecessary,“ she said.

Dr. Dutcher said there was probably a reduction in secondary bacterial infections as well as the viral infections.

The research is more comprehensive than some other previous studies, the authors write.

“Although other studies demonstrated early reductions in RTIs and antibiotic prescribing during the COVID-19 pandemic, to our knowledge, this is the first study to demonstrate a sustained decrease in antibiotic prescribing in pediatric primary care throughout 2020 and early 2021,” they write.

The findings also suggest benefits of preventive measures during the pandemic, the authors say.

“Our data suggest that reducing community viral RTI transmission through social distancing and masking corresponds with a reduction in antibiotic prescribing,” they write.

Kao-Ping Chua, MD, a pediatrician and an assistant professor of pediatrics at the University of Michigan in Ann Arbor, said the reductions indicate one of two things is happening: either children aren’t getting sick as often during the pandemic or they are getting sick, but not coming in.

“Our data suggest that reducing community viral RTI transmission through social distancing and masking corresponds with a reduction in antibiotic prescribing,” they write.

Kao-Ping Chua, MD, a pediatrician and an assistant professor of pediatrics at the University of Michigan in Ann Arbor, said the reductions indicate one of two things is happening: either children aren’t getting sick as often during the pandemic or they are getting sick, but not coming in.

The risk of myocarditis after immunization with mRNA-based vaccines against SARS-CoV-2 raised concerns when it came to light in early 2021. But as report after report showed such cases to be rare and usually mild and self-limited, focus has turned to the “how and why.”  

The mechanism linking the BNT162b2 (Pfizer-BioNTech) and especially mRNA-1273 (Moderna) vaccines to the occurrence of myocarditis is unclear for now, but one potential driver may be tied to a peculiarity that became apparent early: It occurs overwhelmingly in younger males, from 16 to perhaps 40 or 50 years of age. Excess risk has not been consistently seen among women, girls, and older men.

That observation has led to speculation that higher testosterone levels in adolescent boys and young men may somehow promote the adverse vaccine effect, whereas greater levels of estrogen among girls and women in the same age range may be cardioprotective.
 

Unlikely, brief, and ‘benign’

“Most of the myocarditis is benign, by which I mean that maybe the patients are admitted due to chest pain, but without reduction in ventricular function,” Enrico Ammirati, MD, PhD, a myocarditis expert at De Gasperis Cardio Center and Transplant Center, Niguarda Hospital, Milan, said in an interview.

In a Nov. 14 address on this topic at the annual scientific sessions of the American Heart Association, Dror Mevorach, MD, described the typical case presentation as “mild” and one that clears in fairly short order based on resolution of “clinical symptoms, inflammatory markers and troponin decline, EKG normalization, echo normalization, and a relatively short length of hospital stay.”

Dr. Mevorach, of Hadassah Hebrew University Medical Center, Jerusalem, subsequently published the findings in a report in the New England Journal of Medicine that described 136 confirmed myocarditis cases among more than 5 million people in Israel immunized with the Pfizer-BioNTech vaccine. Myocarditis was considered “mild” in 129 cases, or 95%.

And the risk is tiny, compared with myocarditis from infection by SARS-CoV-2, not to mention the possibility of nasty clinical COVID-19 complications such as pneumonia and pulmonary embolism, Dr. Mevorach observed.

Many other reports agree that the incidence is minimal, especially given the rewards of vaccination. In a separate NEJM publication in September 2021 – from Noam Barda, MD, Clalit (Israel) Research Institute, and colleagues on 1.7 million people in that country, about half unvaccinated and half given the Pfizer-BioNTech vaccine – there were an estimated 2.7 cases of  myocarditis per 100,000 vaccinated persons. There were also 11 cases of myocarditis per 100,000 persons who were positive for SARS-CoV-2 infection.

And in a recent case series of vaccinated people aged 16 or older, the myocarditis rate after a first or second Pfizer-BioNTech or Moderna injection was estimated at 1 or fewer per 100,000. The corresponding estimate was 4 such cases per 100,000 after a positive SARS-CoV-2 test among the same population, notes a report published Dec.14, 2021, in Nature Medicine.

In general, “the risk of any kind of cardiac injury is vastly lower with a vaccine than it is with the actual viral infection,” Leslie T. Cooper Jr., MD, a myocarditis expert and clinical trialist at the Mayo Clinic, Jacksonville, Fla., said in an interview. With the mRNA-based vaccines, “we do not have any conceivable danger signal that would outweigh the benefit of vaccination.”
 

Males of a certain age

Evidence that such myocarditis predominates in young adult men and adolescent boys, especially following a second vaccine dose, is remarkably consistent.

The risk was elevated only among mRNA-based vaccine recipients who were younger than 40 in the recent Nature Medicine analysis. Among that group, estimates after a second dose numbered fewer than 1 case per 100,000 for Pfizer-BioNTech and 1.5 per 100,000 for Moderna.

In a third analysis from Israel – also in NEJM, from Guy Witberg, MD, Rabin Medical Center, Petah Tikva, and colleagues, based on 2.5 million people aged 16 and older with at least one Pfizer-BioNTech injection – 2.1 cases per 100,000 were estimated overall, but the number rose to 10.7 per 100,000 among those aged 16-29 years.

In Dr. Mevorach’s NEJM report, estimates after a second Pfizer-BioNTech vaccine dose were 1 per 26,000 males versus 1 in 218,000 females, compared with 1 myocarditis case in 10,857 persons among “the general unvaccinated population.”

Most recipients of a first vaccine dose were younger than 50, and 16- to 29-year-olds accounted for most who completed two doses, noted Dr. Mevorach. Younger males bore the brunt of any myocarditis: the estimated prevalence after a second dose among males aged 16-19 was 1 per 6,637, compared with 1 per 99,853 females in the same age range, the group reported.

In the BMJ report, based on about 5 million people 12 years of age or older in Denmark, the estimated rates of myocarditis or pericarditis associated with Moderna immunization were 2 per 100,000 among women but 6.3 per 100,000 for men. The incidence and sex difference was much lower among those getting the Pfizer-BioNTech vaccine: 1.3 per 100,000 and 1.5 per 100,000 in women and men, respectively.
 

Sex hormones may be key

The predominance of vaccine-associated myocarditis among adolescent and young adult males is probably more about the myocarditis itself than the vaccines, observed Biykem Bozkurt, MD, PhD, who has been studying COVID-related myocarditis at Baylor College of Medicine, Houston.

Male sex historically is associated in both epidemiologic studies and experimental models with a greater propensity for most any form of myocarditis, Dr. Bozkurt said in an interview. Given that males aged 16-19 or so appear to be at highest risk of myocarditis as a complication of SARS-CoV-2 vaccination, the mechanism may well be related to sex hormones.  

“Therefore, testosterone is implicated as a player in their higher risk of inflammation and injury and lack of adaptive response in terms of healing, and in terms of prevention of injury,” Dr. Bozkurt said. For its part, estrogen inhibits proinflammatory processes and, in particular, “blunts cell-mediated immune responses.”

“We don’t know the mechanism, but a theory that attributes a protective role to estrogen, or a risk associated with testosterone, is reasonable. It makes sense, at least based on epidemiological data,” Dr. Ammirati agreed. Still, “we do not have any direct evidence in human beings.”

Sex-associated differences in experimental myocarditis have been reported in the journals for at least 70 years, but “the testosterone literature and the estrogen literature have not been evaluated in detail in vaccine-associated myocarditis,” Dr. Cooper said.

Most myocarditis in the laboratory is viral, Dr. Cooper observed, and “the links between testosterone, viruses, and inflammation have been pretty well worked out, I would say, if you’re a mouse. If you’re a human, I think it’s still a bit uncertain.”

Were it to apply in humans, greater testosterone levels might independently promote myocarditis, “and if estrogen is cardioprotective, it would be another mechanism,” Dr. Cooper said. “That would translate to slight male predominance in most kinds of myocarditis.”

In males, compared with females, “the heart can be more vulnerable to events such as arrhythmias or to immune-mediated phenomena. So, probably there is also higher vulnerability to myocarditis in men,” Dr. Ammirati noted.

Male predominance in vaccine-related myocarditis is provocative, so it’s worth considering whether testosterone is part of the mechanism as well as the possibility of estrogen cardioprotection, Dr. Ammirati said. But given limitations of the animal models, “we don’t really have robust data to support any part of that.”

Although myocarditis is in some way immune mediated, “and hormones can modulate the response,” the mechanism has to be more than just sex hormones, he said. “They probably cannot explain the specificity for the heart. It’s not a systemic response, it’s an organ-specific response.”
 

Modulation of immune responses

Details about the immune processes underlying mRNA-vaccine myocarditis, hormone modulated or not, have been elusive. The complication doesn’t resemble serum sickness, nor does it seem to be a reaction to infection by other cardiotropic viruses, such as coxsackie virus B, a cause of viral myocarditis, Dr. Bozkurt said. The latter had been a compelling possibility because such hypersensitivity to smallpox vaccination is well recognized.

“We don’t know the mechanism, that’s the short answer. But there are many hypotheses,” she said. One candidate widely proposed in the literature: autoantibodies driven by molecular mimicry between the SARS-CoV-2 spike protein targeted by the mRNA vaccines and a structurally similar myocardial protein, possibly alpha-myosin, noted Dr. Bozkurt and colleagues in a recent publication.

But elevations in specific “antiheart antibodies” have not been documented in recipients of the two mRNA-based vaccines, said Dr. Cooper. “So, I would say that – although molecular mimicry is a well-established mechanism of, for example, rheumatic carditis after a streptococcal A infection – that has not been demonstrated yet for COVID-19 mRNA vaccination–related myocarditis.”

“We probably won’t know, ever, with a huge level of certainty, the exact mechanisms,” Dr. Cooper added. There is no animal model for vaccine-induced myocarditis, and “We’re still talking very, very small numbers of patients. The vast majority of them recover,” and so don’t generally provide mechanistic clues.  
 

Prospects for younger children

Vaccination against SARS-CoV-2 has now been authorized by the Centers for Disease Control and Prevention for kids as young as 5-11 years, using the Pfizer-BioNTech vaccine. Experience so far suggests the immunization is safe in that age group with negligible risk of myocarditis or other complications. But with prospects of possible authorization in children younger than 5, should myocarditis be a concern for them?

Probably not, if the complication is driven primarily by sex hormones, Dr. Cooper proposed. “One would predict that before puberty you would have a lower – much, much lower – rate of myocarditis in males than you would in the 16- to 19-year-old range, and that it would be roughly equal to females.” Dr. Ammirati and Dr. Bozkurt largely agreed.

It remains to be seen whether the vaccine-related myocarditis risk applies to children younger than 12, “but I doubt it. I think it’s going to be puberty-related,” Dr. Bozkurt said. Still, “I don’t want to hypothesize without data.”

SARS-CoV-2 infection was associated with an increased risk for diabetes among youth, whereas other acute respiratory infections were not, new data from the U.S. Centers for Disease Control and Prevention indicate.

The results from two large U.S. health claims databases were published in an early release in the CDC’s Morbidity and Mortality Weekly Report by Catherine E. Barrett, PhD, and colleagues of the CDC’s COVID-19 Emergency Response Team and Division of Diabetes Translation.

Clinicians should monitor individuals younger than 18 years in the months following a SARS-CoV-2 infection for new diabetes onset, they advise.

The findings, which are supported by independent studies in adults, “underscore the importance of COVID-19 prevention among all age groups, including vaccination for all eligible children and adolescents, and chronic disease prevention and treatment,” Dr. Barrett and colleagues say.

Diabetes type couldn’t be reliably distinguished from the databases, which is noted as an important study limitation.

“SARS-CoV-2 infection might lead to type 1 or type 2 diabetes through complex and differing mechanisms,” they say.

Emerging evidence began to suggest, in mid-2020, that COVID-19 may trigger the onset of diabetes in healthy people. A new global registry was subsequently established to collect data on patients with COVID-19–related diabetes, called the CoviDiab registry.
 

Not clear if diabetes after COVID-19 is transient or permanent

From one of the databases used in the new study, known as IQVIA, 80,893 individuals aged younger than 18 years diagnosed with COVID-19 during March 2020 to February 26, 2021, were compared with age- and sex-matched people during that period who did not have COVID-19 and to prepandemic groups with and without a diagnosis of acute respiratory illness during March 1, 2017, to February 26, 2018.

From the second database, HealthVerity, 439,439 youth diagnosed with COVID-19 during March 1, 2020, to June 28, 2021, were compared with age- and sex-matched youth without COVID-19. Here, there was no prepandemic comparison group.

Diabetes diagnoses were coded in 0.08% with COVID-19 vs. 0.03% without COVID-19 in IQVIA and in 0.25% vs. 0.19% in HealthVerity.

Thus, new diabetes diagnoses were 166% and 31% more likely to occur in those with COVID-19 in IQVIA and HealthVerity, respectively. And in IQVIA, those with COVID-19 were 116% more likely to develop diabetes than were those with prepandemic acute respiratory illnesses. Those differences were all significant, whereas non–SARS-CoV-2 respiratory infections were not associated with diabetes, Dr. Barrett and colleagues say.

In both databases, diabetic ketoacidosis (DKA) was more common at diabetes onset among those with, vs. without, COVID-19: 48.5% vs. 13.6% in IQVIA and 40.2% vs. 29.7% in HealthVerity. In IQVIA, 22.0% with prepandemic acute respiratory illness presented with DKA.

Dr. Barrett and colleagues offer several potential explanations for the observed association between COVID-19 and diabetes, including a direct attack on pancreatic beta cells expressing angiotensin-converting enzyme 2 receptors, or via stress hyperglycemia resulting from cytokine storm and alterations in glucose metabolism.

Another possibility is the precipitation to diabetes from prediabetes; the latter is a condition present in one in five U.S. adolescents.

Steroid treatment during hospitalization might have led to transient hyperglycemia, but only 1.5% to 2.2% of diabetes codes were for drug- or chemical-induced diabetes. The majority were for type 1 or 2.

Alternatively, pandemic-associated weight gain might have also contributed to risks for both severe COVID-19 and type 2 diabetes.

“Although this study can provide information on the risk for diabetes following SARS-CoV-2 infection, additional data are needed to understand underlying pathogenic mechanisms, either those caused by SARS-CoV-2 infection itself or resulting from treatments, and whether a COVID-19–associated diabetes diagnosis is transient or leads to a chronic condition,” Dr. Barrett and colleagues conclude.

First-line treatment of neonatal sepsis in low- and middle-income countries (LMICs) with ampicillin-gentamicin – as recommended by the World Health Organization – needs to be reassessed, a retrospective, observational cohort study suggests. Rates of resistance to this particular antibiotic combination are extremely high in LMICs, and this treatment is unlikely to save many neonatal patients, according to the study’s results.

“The WHO guidelines are over 10 years old, and they are actually based on high-income country data, whereas data reported from low-income countries are reported by private labs, and they do not cater to the lower socioeconomic groups within these countries, which is important data to capture,” Timothy Walsh, MD, University of Oxford, United Kingdom, told this news organization.

“The main take-home message from our data is that ampicillin-gentamicin doesn’t work for most of the Gram-negative isolates we tested, and while there are alternatives, their use is confounded by [a lack of] financial support,” he added.

The study was published online in The Lancet Infectious Diseases.
 

BARNARDS study

In this substudy of the Burden of Antibiotic Resistance in Neonates from Developing Societies (BARNARDS) study, investigators focused on the effectiveness of antibiotic therapies after taking into account the high prevalence of pathogen resistance to ampicillin-gentamicin. Participating countries included Bangladesh, Ethiopia, India, Nigeria, Pakistan, Rwanda, and South Africa.

“Blood samples were obtained from neonates presenting with clinical signs of sepsis,” the authors note, “and WGS [whole-genome sequencing] and MICs [minimum inhibitory concentrations] for antibiotic treatment were determined for bacterial isolates from culture-confirmed sepsis.” Between Nov. 2015 and Feb. 2018, 36,285 neonates were enrolled into the main BARNARDS study, of whom 9,874 had clinically diagnosed sepsis and 5,749 had antibiotic data.

A total of 2,483 neonates had culture-confirmed sepsis, and WGS data were available for 457 isolates taken from 442 neonates. Slightly over three-quarters of the 5,749 neonates who had antibiotic data received first-line ampicillin-gentamicin. The other three most commonly prescribed antibiotic combinations were ceftazidime-amikacin, piperacillin-tazobactam-amikacin, and amoxicillin-clavulanate-amikacin.

Neonates treated with ceftazidime-amikacin had a 68% lower reported mortality than those treated with ampicillin-gentamicin at an adjusted hazard ratio of 0.32 (95% confidence interval, 0.14-0.72; P = .006), the investigators report. In contrast, no significant differences in mortality rates were reported for neonates treated with amoxicillin-clavulanate-amikacin or piperacillin-tazobactam-amikacin compared to those treated with ampicillin-gentamicin.

Investigators were careful to suggest that mortality effects associated with the different antibiotic combinations might have been confounded by either country-specific effects or underreporting of mortality, as a large proportion of neonates who were treated with ampicillin-gentamicin were followed for fewer than 10 days. However, in an unreported aspect of the same study, neonatal mortality from sepsis dropped by over 50% in two federally funded sites in Nigeria that changed their treatment from the WHO-recommended ampicillin-gentamicin regimen to ceftazidime-amikacin – which Dr. Walsh suggested was an endorsement of ceftazidime-amikacin over ampicillin-gentamicin if ever there was one.
 

Gram-negative resistance

In looking at resistance patterns to the antibiotic combinations used in these countries, investigators found that almost all Gram-negative isolates tested were “overwhelmingly resistant” to ampicillin, and over 70% of them were resistant to gentamicin as well. Extremely high resistance rates were also found against Staphylococcus spp, which are regarded as intrinsically resistant to ampicillin, rendering it basically useless in this particular treatment setting.

Amikacin had much lower level of resistance, with only about 26% of Gram-negative isolates showing resistance. In terms of coverage against Gram-negative isolates, the lowest level of coverage was provided by ampicillin-gentamicin at slightly over 28%, compared with about 73% for amoxicillin-clavulanate-amikacin, 77% for ceftazidime-amikacin, and 80% for piperacillin-tazobactam-amikacin.

In contrast, “Gram-positive isolates generally had reduced levels of resistance,” the authors state. As Dr. Walsh noted, the consortium also did an analysis assessing how much the antibiotic combinations cost and how much payment was deferred to the parents. For example, in Nigeria, the entire cost of treatment is passed down to the parents, “so if they are earning, say, $5.00 a day and the infant needs ceftazidime-amikacin, where the cost per dose is about $6.00 or $7.00 a day, parents can’t afford it,” Dr. Walsh observed.

This part of the conversation, he added, tends to get lost in many studies of antibiotic resistance in LMICs, which is a critical omission, because in many instances, the choice of treatment does come down to affordability. “It’s all very well for the WHO to sit there and say, ampicillin-gentamicin is perfect, but the combination actually doesn’t work in over 70% of the Gram-negative bacteria we looked at in these countries,” Dr. Walsh emphasized.

“The fact is that we have to be a lot more internationally engaged as to what’s actually happening in poorer populations, because unless we do, neonates are going to continue to die,” he said.
 

Editorial commentary

Commenting on the findings, lead editorialist Luregn Schlapbach, MD, PhD, of University Children’s Hospital Zurich, Switzerland, pointed out that the study has a number of limitations, including a high rate of dropouts from follow-up. This could possibly result in underestimation of neonatal mortality as well as country-specific biases. Nevertheless, Dr. Schlapbach feels that the integration of sequential clinical, genomic, microbiologic, drug, and cost data across a large network in LMIC settings is “exceptional” and will serve to inform “urgently needed” clinical trials in the field of neonatal sepsis.

“At present, increasing global antibiotic resistance is threatening progress against neonatal sepsis, prompting urgency to develop improved measures to effectively prevent and treat life-threatening infections in this high-risk group,” Dr. Schlapbach and colleagues write.

“The findings from the BARNARDS study call for randomized trials comparing mortality benefit and cost efficiency of different antibiotic combinations and management algorithms to safely reduce unnecessary antibiotic exposure for neonatal sepsis,” the editorialists concluded.

The authors and editorialists have disclosed no relevant financial relationships.

For those of us who see adolescent patients on a regular basis, it seems that they use new vocabulary almost every day. While you may not need to know what “lit” means, you probably do need to understand terms used to describe your patients’ identities. At times it feels like we, as providers, have to be on TikTok to keep up with our patients, and while this may be an amusing way to educate ourselves, a judicious Google search can be much more helpful. The interesting part about LGBTQ+ terminology is that it stems from the community and thus is frequently updated to reflect our evolving understanding of gender, sexuality, and identity. That being said, it can make it difficult for those who are not plugged in to the community to keep up to date. While we have learned in medicine to use accurate terminology and appropriate three-letter acronyms (or “TLAs” as one of my residents referenced them when I was a medical student) to describe medical conditions, the LGBTQ+ community has its own set of terms and acronyms. These new words may seem daunting, but they are often based in Latin roots or prefixes such as a-, demi-, poly-, and pan-, which may be familiar to those of us who use plenty of other Latin-based terms in medicine and our everyday lives. By paying attention to how people define and use terminology, we can better recognize their true identities and become better providers.

The first, and perhaps most important, piece of advice is to maintain cultural humility. Know when to admit you don’t recognize a term and politely ask the definition. For example, the first time I heard the term “demiboy” I said “I’m not familiar with that word. Can you explain what it means to you?” Phrasing the question as such is also helpful in that it gives the individuals a chance to really define their identity. In addition, some words may be used differently by various individuals and by asking what the word means to them, you can have a better understanding of how they are using the terminology. In this particular instance, the patient felt more masculine, but not 100%, partway between agender (meaning having no gender identity) and being “all male.” By embracing cultural humility, we place the patients in the role of expert on their own identity and orientation. According to Maria Ruud, DNP, of the University of Minnesota, Minneapolis, cultural humility is the “ongoing self-reflection and education …[seeking] to gain an awareness of their own assumptions and biases that may contribute to health disparities.”¹

For those of us who see adolescent patients on a regular basis, it seems that they use new vocabulary almost every day. While you may not need to know what “lit” means, you probably do need to understand terms used to describe your patients’ identities. At times it feels like we, as providers, have to be on TikTok to keep up with our patients, and while this may be an amusing way to educate ourselves, a judicious Google search can be much more helpful. The interesting part about LGBTQ+ terminology is that it stems from the community and thus is frequently updated to reflect our evolving understanding of gender, sexuality, and identity. That being said, it can make it difficult for those who are not plugged in to the community to keep up to date. While we have learned in medicine to use accurate terminology and appropriate three-letter acronyms (or “TLAs” as one of my residents referenced them when I was a medical student) to describe medical conditions, the LGBTQ+ community has its own set of terms and acronyms. These new words may seem daunting, but they are often based in Latin roots or prefixes such as a-, demi-, poly-, and pan-, which may be familiar to those of us who use plenty of other Latin-based terms in medicine and our everyday lives. By paying attention to how people define and use terminology, we can better recognize their true identities and become better providers.

Justin L. Berk, MD, MPH, MBA: Welcome back to The Cribsiders, our video recap of our pediatric medicine podcast. We interview leading experts in the field to bring clinical pearls and practice-changing knowledge, and answer lingering questions about core topics in pediatric medicine. Chris, what is our topic today?

Christopher J. Chiu, MD: I was really happy to be able to talk about our recent episode with Dr. Carissa Baker-Smith, a pediatric cardiologist and director of the Nemours preventive cardiology program. She helped us review the pediatric screening guidelines for blood pressure, including initial workup and treatment.

Dr. Berk: This was a really great episode that a lot of people found really helpful. What were some of the key takeaway pearls that you think listeners would be interested in?

Dr. Chiu: We talked about when and how we should be checking blood pressures in children. Blood pressure should be checked at every well-child visit starting at age 3. But if they have other risk factors like kidney disease or a condition such as coarctation of the aorta, then blood pressure should be checked at every visit.

Dr. Berk: One thing she spoke about was how blood pressures should be measured. How should we be checking blood pressures in the clinic?

Dr. Chiu: Clinic blood pressures are usually checked with oscillometric devices. They can differ by manufacturer, but basically they find a mean arterial pressure and then each device has a method of calculating systolic and diastolic pressures. Now after that, if the child’s blood pressure is maybe abnormal, you want to double-check a manual blood pressure using Korotkoff sounds to confirm the blood pressure.

She reminded us that blood pressure should be measured with the child sitting with their back supported, feet flat on the floor, and arm at the level of the heart. Make sure you use the right size cuff. The bladder of the cuff should be 40% of the width of the arm, and about 80%-100% of the arm circumference. She recommends sizing up if you have to.

Dr. Berk: Accuracy of blood pressure management was a really important point, especially for diagnosis at this stage. Can you walk us through what we learned about diagnosis of hypertension?

Dr. Chiu: The definitions of hypertension come from the Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents. Up until the age of 13, they define prehypertension as systolic and diastolic blood pressures between the 90th and 95th percentile, or if the blood pressure exceeds 120/80 mm Hg. Hypertension is defined when blood pressure reaches the 95th percentile. Now age 13 is when it gets a little hazy. Many changes in the guidelines happen at age 13, when hypertension starts being defined by adult guidelines. The 2017 adult hypertension guidelines define stage 1 hypertension as 130/89 to 139/89, and stage 2 hypertension as greater than 140/90.

Dr. Berk: How about workup of hypertension? The work of pediatric hypertension is always a little bit complex. What are some of the pearls you took away?

Dr. Chui: She talked about tailoring the workup to the child. So when we’re doing our workup, obviously physical exam should be the first thing we do. You have to assess and compare pulses, which is one of the most important parts of the initial evaluation. Obviously, looking at coarctation of the aorta, but also looking for things like a cushingoid appearance. If the child is less than 6 years of age, she recommends a referral to nephrology for more comprehensive renovascular workup, which probably will include renal ultrasound, urinalysis, metabolic panel, and thyroid studies.

We have to be cognizant of secondary causes of hypertension, such as endocrine tumors, hyperthyroidism, aortic disease, or even medication-induced hypertension. She told us that in the majority of these cases, especially with our obese older children, primary hypertension or essential hypertension is the most likely cause.

Dr. Berk: That was my big takeaway. If they’re really young, they need a big workup, but otherwise it is likely primary hypertension. What did we learn about treatment?

Dr. Chui: Just as we tailor our assessment to the child, we also have to tailor treatment. We know that lifestyle modification is usually the first line of treatment, especially for primary hypertension, and Dr. Baker-Smith tells us that we really need to perform counseling that meets the patient where they are. So if they like dancing to the newest TikTok trends or music videos, maybe we can encourage them to move more that way. Using our motivational interviewing skills is really key here.

If you want to start medication, Dr. Baker-Smith uses things like low-dose ACE inhibitors or calcium channel blockers, but obviously it’ll be tailored to the patient and any underlying conditions.

Dr. Berk: That’s great – a lot of wonderful pearls on the diagnosis and management of pediatric hypertension. Thank you for joining us for another video recap of The Cribsiders pediatric podcast.

A specialty group is asking federal and state governments to preserve and expand access to telehealth services for children with developmental and behavioral problems.

Citing the success during the COVID-19 pandemic of telehealth for these patients, the Society for Developmental and Behavioral Pediatrics (SDBP) has issued a position statement in its official journal calling for continued use of video and telephone for home-based diagnostic assessments, medication management follow-ups, and therapeutic interventions for children  with autism spectrum disorder, attention-deficit/hyperactivity disorder, and other neurodevelopmental conditions.

“Telehealth offers plenty of opportunities for quick check-ins. It can offer some crisis management opportunities ... to address a parent’s concern about challenging behaviors or navigating school system issues or developmental needs,” lead author Robert D. Keder, MD, assistant professor of pediatrics at University of Connecticut, Farmington, and cochair of SDBP’s Advocacy Committee, told this news organization.

“The video visit does really offer us so much more. It’s so enriching and lets us as providers meet the child in their natural home environment. The real magic of a video visit is we haven’t done house calls as a medical society for decades. But now, literally, the power of telehealth lets us do a house call.”

In the face of the pandemic, emergency government policies allowed care to continue remotely via telehealth, including video and phone calls. The policies have allowed patients to have video visits in their own home, lifted provider licensure requirements for visits across state lines, and allowed reimbursement not only for video visits but also for telephone encounters.

As a result, the field of developmental and behavioral pediatrics (DBP) has recognized telehealth as a viable and useful model of care for children with neurodevelopmental disorders, said Neelkamal Soares, MD, a member of the society’s board and a coauthor of the position paper.

“Telehealth has been helpful in mitigating barriers families often face when attending in-person visits,” such as the lack of transportation and child care, missed work hours, and other issues, said Dr. Soares, professor of pediatric and adolescent medicine at Western Michigan University Stryker in Kalamazoo. At the same time, the growth in the use of the technology has highlighted additional obstacles to equitable access to care, including broadband connectivity, digital literacy, and the availability of interpretation and sign language services, he said.

Dr. Keder said telehealth has enabled him to better help with behavior management by observing children where they are most comfortable. Remote visits also allow him to consider information such as furniture arrangements and how that can affect the patient’s living conditions, and also sibling interactions, learning and homework, eating, and sleep.

Telemedicine conferences enable DBP specialists to facilitate care collaboration with different members of the patient’s care team. Consent from a family and a click of a button allows for therapists, early intervention specialists, teachers, school nurses, or even primary care providers the capacity to participate in a telehealth visit, he said.

Dr. Keder said the future of telehealth is uncertain. The policies from the pandemic may expire in the near term and vary from state to state. The goal of the policy statement is to advocate for legislation and policies that support ongoing, equitable, home-based telehealth care for patients seen by DBP providers while ensuring equitable access to DBP in general.

Kate Benton, PhD, a clinical psychologist with Lurie Children’s Hospital at Northwestern Medicine Central DuPage Hospital in Winfield, Ill., said the society has done an excellent job of explaining the need to maintain telehealth in light of the shortage of pediatricians, clinical psychologists, and other professionals in the field.

“Telehealth has opened new avenues for these patients who otherwise have difficulty seeing specialists. This is a population of children who without telehealth have significant challenges in getting access to care,” she said.

Wendy Fournier, mother of an autistic child and president of the National Autism Association, said telehealth can be beneficial for some individuals with the disorder.

“There are many aspects of in-person doctor visits that can be overwhelming, including bright lights, many people talking, waiting for the doctor, being comfortable with the doctor’s touch, etc.,” Ms. Fournier said in an interview. “All of these things can cause sensory and emotional dysregulation leading to overwhelming anxiety and fear.”

Visits to the doctor can be especially difficult for people who are nonverbal and unable to express their discomfort, said. 

“At my daughter’s last medical appointment, she could not stay in the exam room and pulled me out the door. Thankfully, we have an understanding and compassionate physician who finished our appointment in our car. I believe that telehealth visits should remain available as a necessary and vital accommodation for people with disabilities,” Ms. Fournier said.
 

False equivalence?

Dr. Soares said researchers have attempted to assess the evidence of telehealth benefits in such situations as ADHD, cognitive behavioral therapy, and parent training. 

“There is a paucity of published studies that specifically look at different conditions and compare in-person to telehealth visits, but these are ongoing in autism diagnostics and other areas by several SDBP members,” he said. “Stay tuned.”

Dr. Keder added that telehealth will never replace in-person visits, but the availability of this new option gives developmental pediatricians flexibility in strategies in treating and evaluating patients.

“Both are helpful and viable models. In the pandemic, we were forced out of necessity to embrace telehealth,” he said. “Because of this, we are seeing the power and benefits telehealth offers. Now many families like a mixture of alternating in person with telehealth visits.”

The policy statement cites research that finds patients are highly satisfied with telehealth and that telehealth may cost less than in-office visits.

The report stresses that equitable access to devices needed for telehealth visits is a concern because there is disproportionate access to required technology, especially in rural and underserved communities. The Federal Communications Commission has provided grants to eligible families to offset the cost, in part, for a laptop, desktop computer, or tablet. However, more is still needed, the group said.

The position paper calls for:

• Equitable access to the infrastructure and technology for telehealth, including greater access to broadband services in rural and underserved areas.
• Increased access to devices needed to connect children with neurodevelopmental disorders with critical health care services.
• Reimbursement of interpretation services for the people who are deaf and/or have limited English proficiency.
• Mitigation of geographic barriers to accessing DBP care.
• Permitting patients to access telehealth from their home or whichever physical location provides opportunities for safe and timely care, especially for established patients.
• Ensuring more engagement by state medical licensing boards to join the Interstate Medical Licensing Compact to provide care by telehealth when there is already an insufficient geographic distribution of that type of provider in a state, as is being conducted in the field of psychology.
• Ensuring ongoing reimbursement.
• Parity in reimbursement for telehealth in-person visits.
• Increased funding for research looking into outcomes, quality, and effectiveness of telehealth services at the federal and state levels.

“Our organization can work with families to educate lawmakers, insurance administrators, and organizational leaders about the value that telehealth holds in the care of their child and family,” Dr. Soares said. “We can also conduct research to add to the evidence based around the topic to further the science around telehealth outcomes and equivalency to in-person settings.”

“With the current workforce shortage in DBP and behavioral health it is more critical than ever to maintain access to care,” Dr. Keder added. “The pandemic has provided an opportunity to better harness the amazing power of telehealth to allow for access to equitable care for families. We hope that this statement moves legislators, leaders, and voters to continue to advocate for ongoing telehealth at both the state, federal, and organizational levels.”

Dr. Benton, Dr. Keder, and Dr. Soares have disclosed no financial conflicts of interest.

Citing the success during the COVID-19 pandemic of telehealth for these patients, the Society for Developmental and Behavioral Pediatrics (SDBP) has issued a position statement in its official journal calling for continued use of video and telephone for home-based diagnostic assessments, medication management follow-ups, and therapeutic interventions for children  with autism spectrum disorder, attention-deficit/hyperactivity disorder, and other neurodevelopmental conditions.

“Telehealth offers plenty of opportunities for quick check-ins. It can offer some crisis management opportunities ... to address a parent’s concern about challenging behaviors or navigating school system issues or developmental needs,” lead author Robert D. Keder, MD, assistant professor of pediatrics at University of Connecticut, Farmington, and cochair of SDBP’s Advocacy Committee, told this news organization.

“The video visit does really offer us so much more. It’s so enriching and lets us as providers meet the child in their natural home environment. The real magic of a video visit is we haven’t done house calls as a medical society for decades. But now, literally, the power of telehealth lets us do a house call.”

In the face of the pandemic, emergency government policies allowed care to continue remotely via telehealth, including video and phone calls. The policies have allowed patients to have video visits in their own home, lifted provider licensure requirements for visits across state lines, and allowed reimbursement not only for video visits but also for telephone encounters.

As a result, the field of developmental and behavioral pediatrics (DBP) has recognized telehealth as a viable and useful model of care for children with neurodevelopmental disorders, said Neelkamal Soares, MD, a member of the society’s board and a coauthor of the position paper.

“Telehealth has been helpful in mitigating barriers families often face when attending in-person visits,” such as the lack of transportation and child care, missed work hours, and other issues, said Dr. Soares, professor of pediatric and adolescent medicine at Western Michigan University Stryker in Kalamazoo. At the same time, the growth in the use of the technology has highlighted additional obstacles to equitable access to care, including broadband connectivity, digital literacy, and the availability of interpretation and sign language services, he said.

Dr. Keder said telehealth has enabled him to better help with behavior management by observing children where they are most comfortable. Remote visits also allow him to consider information such as furniture arrangements and how that can affect the patient’s living conditions, and also sibling interactions, learning and homework, eating, and sleep.

Telemedicine conferences enable DBP specialists to facilitate care collaboration with different members of the patient’s care team. Consent from a family and a click of a button allows for therapists, early intervention specialists, teachers, school nurses, or even primary care providers the capacity to participate in a telehealth visit, he said.

Dr. Keder said the future of telehealth is uncertain. The policies from the pandemic may expire in the near term and vary from state to state. The goal of the policy statement is to advocate for legislation and policies that support ongoing, equitable, home-based telehealth care for patients seen by DBP providers while ensuring equitable access to DBP in general.

Kate Benton, PhD, a clinical psychologist with Lurie Children’s Hospital at Northwestern Medicine Central DuPage Hospital in Winfield, Ill., said the society has done an excellent job of explaining the need to maintain telehealth in light of the shortage of pediatricians, clinical psychologists, and other professionals in the field.

“Telehealth has opened new avenues for these patients who otherwise have difficulty seeing specialists. This is a population of children who without telehealth have significant challenges in getting access to care,” she said.

Wendy Fournier, mother of an autistic child and president of the National Autism Association, said telehealth can be beneficial for some individuals with the disorder.

“There are many aspects of in-person doctor visits that can be overwhelming, including bright lights, many people talking, waiting for the doctor, being comfortable with the doctor’s touch, etc.,” Ms. Fournier said in an interview. “All of these things can cause sensory and emotional dysregulation leading to overwhelming anxiety and fear.”

Visits to the doctor can be especially difficult for people who are nonverbal and unable to express their discomfort, said. 

“At my daughter’s last medical appointment, she could not stay in the exam room and pulled me out the door. Thankfully, we have an understanding and compassionate physician who finished our appointment in our car. I believe that telehealth visits should remain available as a necessary and vital accommodation for people with disabilities,” Ms. Fournier said.
 

False equivalence?

Dr. Soares said researchers have attempted to assess the evidence of telehealth benefits in such situations as ADHD, cognitive behavioral therapy, and parent training. 

“There is a paucity of published studies that specifically look at different conditions and compare in-person to telehealth visits, but these are ongoing in autism diagnostics and other areas by several SDBP members,” he said. “Stay tuned.”

Dr. Keder added that telehealth will never replace in-person visits, but the availability of this new option gives developmental pediatricians flexibility in strategies in treating and evaluating patients.

“Both are helpful and viable models. In the pandemic, we were forced out of necessity to embrace telehealth,” he said. “Because of this, we are seeing the power and benefits telehealth offers. Now many families like a mixture of alternating in person with telehealth visits.”

The policy statement cites research that finds patients are highly satisfied with telehealth and that telehealth may cost less than in-office visits.

The report stresses that equitable access to devices needed for telehealth visits is a concern because there is disproportionate access to required technology, especially in rural and underserved communities. The Federal Communications Commission has provided grants to eligible families to offset the cost, in part, for a laptop, desktop computer, or tablet. However, more is still needed, the group said.

The position paper calls for:

• Equitable access to the infrastructure and technology for telehealth, including greater access to broadband services in rural and underserved areas.
• Increased access to devices needed to connect children with neurodevelopmental disorders with critical health care services.
• Reimbursement of interpretation services for the people who are deaf and/or have limited English proficiency.
• Mitigation of geographic barriers to accessing DBP care.
• Permitting patients to access telehealth from their home or whichever physical location provides opportunities for safe and timely care, especially for established patients.
• Ensuring more engagement by state medical licensing boards to join the Interstate Medical Licensing Compact to provide care by telehealth when there is already an insufficient geographic distribution of that type of provider in a state, as is being conducted in the field of psychology.
• Ensuring ongoing reimbursement.
• Parity in reimbursement for telehealth in-person visits.
• Increased funding for research looking into outcomes, quality, and effectiveness of telehealth services at the federal and state levels.

“Our organization can work with families to educate lawmakers, insurance administrators, and organizational leaders about the value that telehealth holds in the care of their child and family,” Dr. Soares said. “We can also conduct research to add to the evidence based around the topic to further the science around telehealth outcomes and equivalency to in-person settings.”

“With the current workforce shortage in DBP and behavioral health it is more critical than ever to maintain access to care,” Dr. Keder added. “The pandemic has provided an opportunity to better harness the amazing power of telehealth to allow for access to equitable care for families. We hope that this statement moves legislators, leaders, and voters to continue to advocate for ongoing telehealth at both the state, federal, and organizational levels.”

Dr. Benton, Dr. Keder, and Dr. Soares have disclosed no financial conflicts of interest.

FROM FRONTIERS IN PHYSIOLOGY

Researchers have identified a potential cause of molar hypomineralization (MH), or “chalky teeth,” an underrecognized condition affecting one in five children worldwide. The discovery could lead to preventive medical therapies to reduce dental caries and extractions, they said.

According to a team led by biochemist Michael J. Hubbard, BDS, PhD, professor in the department of medicine, dentistry, and health sciences at the University of Melbourne, the “groundbreaking” research found that the failure of enamel to adequately harden is associated with exposure to serum albumin while teeth are developing. The blood protein “poisons” the growth of mineral crystals rather than injure the cells that deposit enamel, they reported.

The investigators, including researchers from Chile, said their findings hold promise for better clinical management of MH and open a new door into research on the broader pathogenesis and causes of the condition.

“We hope this breakthrough will eventually lead to medical prevention of MH, prompting global health benefits including major reductions in childhood tooth decay,” they wrote in an article published online Dec. 21 in Frontiers in Physiology.
 

More than cosmetic

Chalky teeth, characterized by discolored enamel spots, are not merely a cosmetic problem. The condition can lead to severe toothache, painful eating, tooth decay, and even abscesses and extractions. Although its triggers have eluded dental research for a century, Dr. Hubbard’s group said fossilized blood proteins such as albumin in the tooth appear to be at least one cause.

Biochemical evidence indicates that serum albumin surrounding developing teeth is normally excluded from enamel, Dr. Hubbard said in an interview. “Given that albumin binds strongly to hydroxyapatite-based mineral and blocks its growth, we infer that the epithelial barrier – the enamel-forming cells termed ameloblasts and normally responsible for excluding albumin – must break down in places in response to medical triggers.”

This breach enables localized infiltration of albumin, which then blocks further hardening of soft, immature enamel, leading to residual spots or patches of chalky enamel once the tooth eventually erupts into the mouth. “In other words, we infer that chalky enamel spots coincide with localized breaches of an epithelial barrier that are triggered by yet-to-be determined systemic insults,” he said.

Joseph Brofsky, DMD, section head of pediatric dentistry at North Shore LIJ Cohen Children’s Medical Center of New York, in Queens, agreed that that the definitive cause of MH has evaded identification for a hundred years. However, he expressed skepticism about the fossilized blood protein hypothesis.

“That’s a long shot. It’s a possibility, and I’m not ruling it out, but we’re not 100% sure,” said Dr. Brofsky, who was not involved in the research.

In his experience, MH is somewhat less prevalent in the United States, affecting about 1 in 10 children here, which is about half the global rate. “But it’s a problem, and we wish it would go away, but before we know beyond a reasonable doubt what causes this condition, it’s going to be hard to stop it.”

Most cases of MH involve hypomineralization of the 6-year molars, the first adult molars to erupt, but the process starts at birth. “For 6-year molars, normal hardening of dental enamel takes place from the early postnatal period through infancy,” Dr. Hubbard said.

The 2-year and 12-year molars are affected about half as frequently as their 6-year counterparts, “so this extends the medical-risk window out to early school days, and slightly back to the perinatal period for the 12-year and 2-year molars, respectively,” he said.

A critical question is which childhood illnesses are most likely to set the stage for MH, he added. “Forty-plus years of epidemiology have failed to nail a specific cause or causal association. But given the high prevalence of MH – 20% in otherwise healthy kids – naturally we suspect some common illnesses are the culprits,” he said. “But which diseases, which medications, and which combinations?”

Dr. Hubbard’s advice to pediatricians is to be alert to MH: “If you’re inspecting a child’s throat, then why not look at their back teeth, too – particularly when they’re getting their new molars at 2, 6, and 12 years?”

The study was supported by the Melbourne Research Unit for Facial Disorders Department of Pharmacology & Therapeutics, Department of Paediatrics, and Faculty of Medicine, Dentistry, and Health Sciences at the University of Melbourne. The authors and Dr. Brofsky have disclosed no relevant financial relationships.
