More than 5% of cases of sudden infant death may be linked to maternal obesity, new research showed.

“When a parent has a child that dies of sudden unexplained infant death [SUID], it’s extremely devastating,” said Jan-Marino Ramirez, PhD, the Zain Nadella Endowed Chair in Pediatric Neurosciences at the University of Washington, Seattle, and director of the Center for Integrative Brain Research at Seattle Children’s Hospital. “And the most devastating problem is that there’s no clear answer. Understanding the mechanisms will help parents understand.”

The study was published online in JAMA Pediatrics.

In the United States, approximately 3500 cases of SUID are reported yearly. After educational campaigns in the 1990s demonstrating safe infant sleep positions, rates of these fatalities dropped but have since plateaued.
 

Maternal Obesity During Pregnancy

Rates of maternal obesity are increasing globally, and more than half of women of reproductive age are overweight or obese.

“Maternal obesity before pregnancy affects placental development, gene expression, and has long-term implications,” said Patrick Catalano, MD, a professor in residence at the Departments of Reproductive Endocrinology and Obstetrics and Gynecology at Massachusetts General Hospital and Harvard Medical School in Boston.

Maternal obesity is a well-documented risk factor for adverse outcomes of pregnancy including stillbirth, preterm birth, and admission to the neonatal intensive care unit. Swedish researchers in 2014 reported maternal obesity was linked to an increase in infant mortality that increased with body mass index (BMI), but that study did not look specifically at SUID.

For their new study, Dr. Ramirez and colleagues looked at data from all live births in the United States from 2015 to 2019 recorded by the Centers for Disease Control and Prevention and the National Center for Health Statistics. Of the 18,857,694 live births occurring at 28 weeks of gestation or later, 16,545 infants died of a sudden, unexplained cause.

Rates of SUID in babies born to mothers with obesity increased in a statistically significant, dose-dependent manner relative to normal weight mothers. The unadjusted absolute risks for SUID were 0.74 cases per 1000 births for normal weight mothers, 0.99 cases at BMIs between 30 and 35, 1.17 cases at BMIs between 35 and 40, and 1.47 instances at BMI ≥ 40.

After adjustment for maternal age, race, ethnicity, and level of education, the adjusted odds ratio for a case of SUID was 1.39 among women with the highest levels of obesity (95% CI, 1.31-1.47), according to the researchers.

While the study revealed an association between maternal obesity and SUID, the basis for this connection remains unknown, the investigators noted. One possibility for the link is that obesity increases the risk for obstructive sleep apnea, which can result in intermittent hypoxia. That, in turn, causes oxidative stress, which may possibly have effects on the fetus causing effects that eventually lead to SUID in the infant.

An accompanying editorial by Jacqueline Maya, MD; Marie-France Hivert, MD, MMSc; and Lydia Shook, MD, from the Massachusetts General Hospital and Harvard Medical School, suggested that the SUID is unlikely directly influenced by high maternal BMI but rather by the metabolic concerns related to obesity such as inflammation, insulin resistance, and abnormal lipid metabolism. Epigenetics may also play a role.

“We believe the evidence for this study of an association between prepregnancy obesity and SUID is a call to action for the scientific and medical community to better understand the complex interplay of biological, social, and behavioral factors that may lead to SUID, a devastating complication that no family should experience,” the authors of the editorial wrote.

Dr. Ramirez stressed the importance of not initiating guilt because there are many factors in SUID such as genetics that cannot be controlled.

“We are far from saying a baby died because you were obese; that’s an important message to parents,” he said. What he sees as important, rather, is using this new research to elucidate further mechanisms that may allow for more targeted interventions: “If we discover that it’s due to, for example, sleep apnea, that’s something we can prevent.”

The researchers reported no conflicts of interest.

An ancient virus that infected our ancestors tens of millions of years ago may be helping to fuel cancer today, according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.

The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)

Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off. Research in recent years suggests they may play a role in diseases like cancer.

But scientists weren’t exactly sure what that role was, said senior study author Edward Chuong, PhD, a genome biologist at the University of Colorado Boulder.

Most studies have looked at whether endogenous retroviruses code for proteins that influence cancer. But these ancient viral strands usually don’t code for proteins at all.

Dr. Chuong took a different approach. Inspired by scientists who’ve studied how viral remnants regulate positive processes (immunity, brain development, or placenta development), he and his team explored whether some might regulate genes that, once activated, help cancer thrive.

Borrowing from epigenomic analysis data (data on molecules that alter gene expression) for 21 cancers mapped by the Cancer Genome Atlas, the researchers identified 19 virus-derived DNA sequences that bind to regulatory proteins more in cancer cells than in healthy cells. All of these could potentially act as gene regulators that promote cancer.

The researchers homed in on one sequence, called LTR10, because it showed especially high activity in several cancers, including lung and colorectal cancer. This DNA segment comes from a virus that entered our ancestors’ genome 30 million years ago, and it’s activated in a third of colorectal cancers.

Using the gene editing technology clustered regularly interspaced short palindromic repeats (CRISPR), Dr. Chuong’s team silenced LTR10 in colorectal cancer cells, altering the gene sequence so it couldn’t bind to regulatory proteins. Doing so dampened the activity of nearby cancer-promoting genes.

“They still behaved like cancer cells,” Dr. Chuong said. But “it made the cancer cells more susceptible to radiation. That would imply that the presence of that viral ‘switch’ actually helped those cancer cells survive radiation therapy.”

Previously, two studies had found that viral regulators play a role in promoting two types of cancer: Leukemia and prostate cancer. The new study shows these two cases weren’t flukes. All 21 cancers they looked at had at least one of those 19 viral elements, presumably working as cancer enhancers.

The study also identified what activates LTR10 to make it promote cancer. The culprit is a regulator protein called mitogen-activated protein (MAP) kinase, which is overactivated in about 40% of all human cancers.

Some cancer drugs — MAP kinase inhibitors — already target MAP kinase, and they’re often the first ones prescribed when a patient is diagnosed with cancer, Dr. Chuong said. As with many cancer treatments, doctors don’t know why they work, just that they do.

“By understanding the mechanisms in the cell, we might be able to make them work better or further optimize their treatment,” he said.

“MAP kinase inhibitors are really like a sledgehammer to the cell,” Dr. Chuong said — meaning they affect many cellular processes, not just those related to cancer.

“If we’re able to say that these viral switches are what’s important, then that could potentially help us develop a more targeted therapy that uses something like CRISPR to silence these viral elements,” he said. Or it could help providers choose a MAP kinase inhibitor from among the dozens available best suited to treat an individual patient and avoid side effects.  

Still, whether the findings translate to real cancer patients remains to be seen. “It’s very, very hard to go the final step of showing in a patient that these actually make a difference in the cancer,” Dr. Mager said.

More lab research, human trials, and at least a few years will be needed before this discovery could help treat cancer. “Directly targeting these elements as a therapy would be at least 5 years out,” Dr. Chuong said, “partly because that application would rely on CRISPR epigenome editing technology that is still being developed for clinical use.”

TORONTO — Lawrence A. Schachner, MD, would like pediatric dermatologists to adopt a “toxic agent of the year” to raise awareness about the potential harm related to certain topical treatments in babies and young children.

Dr. Schachner, director of the Division of Pediatric Dermatology in the Department of Dermatology & Cutaneous Surgery at the University of Miami, Coral Gables, Florida, said he got the idea from the American Contact Dermatitis Society, which annually names the “Allergen of the Year.”

In pediatric dermatology, the list of potentially toxic products includes topical analgesics such as Castellani paint used for skin infections, alcohols used for umbilical care in newborns, and henna dye used in cosmetics, said Dr. Schachner, professor of pediatrics and dermatology at the University of Miami.

“Any one of those would be excellent toxic substances of the year” that could be the focus of an educational campaign, he told this news organization following his presentation on “Toxicology of Topical Ingredients in Pediatric Dermatology” at the annual meeting of the Society for Pediatric Dermatology on July 14.

Benzene might also be a good candidate for the list, although the jury seems to be still out on its toxicity, said Dr. Schachner.

He talked about the “four Ps” of poisoning — the physician, pharmacy, parents, and pharmaceutical manufacturing — which all have some responsibility for errors that lead to adverse outcomes but can also take steps to prevent them.

During his presentation, Dr. Schachner discussed how babies are especially sensitive to topical therapies, noting that a baby’s skin is thinner and more permeable than that of an adult. And children have a greater body surface-to-weight ratio, so they absorb more substances through their skin.

He also noted that babies lack natural moisturizing factors, and their skin barrier isn’t mature until about age 3-5 years, stressing the need for extreme care when applying a topical agent to a baby’s skin.

Tragic Stories

Dr. Schachner pointed to some instances of mishaps related to toxic topical substances in children. There was the outbreak in the early 1980s of accidental hexachlorophene poisoning among children in France exposed to talc “baby powder.” Of the 204 affected children, 36 died.

The cause was a manufacturing error; the product contained 6.3% hexachlorophene, as opposed to the 0.1% limit recommended by the US Food and Drug Administration (FDA).

Local anesthetics, including lidocaine, dibucaine, and prilocaine, can cause local anesthetic systemic toxicity, a syndrome with symptoms that include central nervous system depression, seizures, and cardiotoxicity. Dr. Schachner described the case of a 3-year-old who developed methemoglobinemia, with seizures, after treatment with an excessive amount of eutectic mixture of local anesthetics (EMLA) cream, which contains both lidocaine and prilocaine.

EMLA shouldn’t be used with methemoglobinemia-inducing agents, such as some antimalarials, analgesics, anesthetics, and antineoplastic agents. It’s not recommended in neonates or for those under 12 months if receiving methemoglobinemia-inducing agents, “and I would keep an eye on it after 12 months of age,” said Dr. Schachner.

He cited a retrospective review of topical lidocaine toxicity in pediatric patients reported to the National Poison Data System from 2000 to 2020. It found 37 cases of toxicity, the most common from application prior to dermatologic procedures (37.5%), which led to two deaths.
 

Not Benign Agents

“These are not benign agents; we have to use them correctly,” Dr. Schachner stressed. When discussing alcohols and antiseptics, he noted that phenol is found in a variety of household disinfectants, gargling products, ointments, and lip balms. Phenol can be used as a chemical peel and is the antiseptic component of Castellani paint. He also referred to cases of alcohol intoxication linked to umbilical care in newborns.

Benzene at elevated levels has been found in some topical benzoyl peroxide acne products and in some sunscreens. There have been suggestions, not strongly substantiated, that benzene may increase the risk for cancer, especially leukemias.

But there is sparse data on the absorption and toxicity of benzene exposure with sunscreen use. The data, he said, include an analysis of National Health and Nutrition Examination Survey data, which found that people who regularly used sunscreens were less likely to have elevated benzene levels compared with those who didn’t use sunscreens.

Turning to insecticides, Dr. Schachner discussed N,N-diethyl-m-toluamide (DEET), the active ingredient in many insect repellents. It helps avoid “some terrible diseases,” including mosquito-borne illnesses such as malaria and tick-borne conditions such as Lyme disease, and is available in several convenient formulations, he said.

When used on children, the American Academy of Pediatrics (AAP) recommends products with no more than 30% DEET. And insect repellents are not recommended for children younger than 2 months, or under clothing or damaged skin, he said.

Dr. Schachner referred to a case series of 18 children who developed DEET-induced encephalopathy; 13 (72%) involved dermal exposure. Three of those with cutaneous exposure died, mostly from neurologic, respiratory, and cardiac issues. “What’s very striking is that 55% of the kids were exposed to DEET of 20% or less, even though the AAP approves DEET at 30%, so maybe that’s something we have to look at,” he said.
 

Medication Patches

With medication patches, especially fentanyl transdermal patches, much can go wrong when it comes to children. This was highlighted by the cases Schachner cited, including an infant who developed acute cytotoxic cerebellar edema from fentanyl patch intoxication.

In another case, emergency room staff found a fentanyl patch stuck to the back of a 3-year-old girl. A CT scan showed global cerebral edema, and the patient progressed to brain death. “This is not a unique case; there have been over 10 such cases in the United States,” said Dr. Schachner. “We should be doing better with fentanyl.”

Nicotine patches can also be dangerous to children, he added. As for other topical agents, there have been reports of toxicity and deaths linked to salicylic acid, commonly used by dermatologists because of its bacteriostatic, fungicidal, keratolytic, and photoprotective properties.

Dr. Schachner cited the case of a 2-month-old where the pediatrician prescribed 50% salicylic acid for seborrheic dermatitis of the scalp, under occlusion. “It’s amazing this child survived; that’s clearly a physician error,” he said.

Henna, a reddish-brown dye derived from the crushed leaves of Lawsonia alba, is used cosmetically for the hair, skin, and nails. Many henna products are mixed with additives, including para-phenylenediamine, which has been associated with dermatitis, asthma, renal failure, and permanent vision loss.

Asked to comment on the presentation, Sheilagh Maguiness, MD, professor of dermatology and pediatrics and chair of pediatric dermatology at the University of Minnesota, Minneapolis, recalled a particularly concerning story in 2008, when the FDA issued a warning about Mommy’s Bliss, a cream containing chlorphenesin and phenoxyethanol as preservatives, promoted to nursing mothers for soothing cracked nipples. There were reports of the cream causing respiratory distress, vomiting, and diarrhea in nursing infants.

Dr. Schachner is chair of Stiefel Laboratories and is an investigator with: Astellas, Berg Pharma, Celgene, Ferndale Labs, Lilly, Medimetriks Pharmaceuticals, Novartis, Organogenesis, Pfizer, Sciton; is a consultant for: Alphyn, Amryt Pharma, Beiersdorf, Brickell, Cutanea, Hoth, Lexington, Mustela, TopMD, Noble Pharma; a speaker for: Novartis, Sanofi-Regeneron, CeraVe; is on the advisory boards of: Almirall, Alphyn, Apogee, Aslan, Biofrontera, CeraVe, Krystal Biotech, Mustela, Noble Pharma, Pfizer, Pierre Fabre, Sanofi-Regeneron; and owns stocks in: TopMD and Alphyn. Dr. Maguiness had no relevant conflicts of interest.

He talked about the “four Ps” of poisoning — the physician, pharmacy, parents, and pharmaceutical manufacturing — which all have some responsibility for errors that lead to adverse outcomes but can also take steps to prevent them.

During his presentation, Dr. Schachner discussed how babies are especially sensitive to topical therapies, noting that a baby’s skin is thinner and more permeable than that of an adult. And children have a greater body surface-to-weight ratio, so they absorb more substances through their skin.

He also noted that babies lack natural moisturizing factors, and their skin barrier isn’t mature until about age 3-5 years, stressing the need for extreme care when applying a topical agent to a baby’s skin.

Tragic Stories

Dr. Schachner pointed to some instances of mishaps related to toxic topical substances in children. There was the outbreak in the early 1980s of accidental hexachlorophene poisoning among children in France exposed to talc “baby powder.” Of the 204 affected children, 36 died.

The cause was a manufacturing error; the product contained 6.3% hexachlorophene, as opposed to the 0.1% limit recommended by the US Food and Drug Administration (FDA).

Local anesthetics, including lidocaine, dibucaine, and prilocaine, can cause local anesthetic systemic toxicity, a syndrome with symptoms that include central nervous system depression, seizures, and cardiotoxicity. Dr. Schachner described the case of a 3-year-old who developed methemoglobinemia, with seizures, after treatment with an excessive amount of eutectic mixture of local anesthetics (EMLA) cream, which contains both lidocaine and prilocaine.

EMLA shouldn’t be used with methemoglobinemia-inducing agents, such as some antimalarials, analgesics, anesthetics, and antineoplastic agents. It’s not recommended in neonates or for those under 12 months if receiving methemoglobinemia-inducing agents, “and I would keep an eye on it after 12 months of age,” said Dr. Schachner.

He cited a retrospective review of topical lidocaine toxicity in pediatric patients reported to the National Poison Data System from 2000 to 2020. It found 37 cases of toxicity, the most common from application prior to dermatologic procedures (37.5%), which led to two deaths.
 

Not Benign Agents

“These are not benign agents; we have to use them correctly,” Dr. Schachner stressed. When discussing alcohols and antiseptics, he noted that phenol is found in a variety of household disinfectants, gargling products, ointments, and lip balms. Phenol can be used as a chemical peel and is the antiseptic component of Castellani paint. He also referred to cases of alcohol intoxication linked to umbilical care in newborns.

Benzene at elevated levels has been found in some topical benzoyl peroxide acne products and in some sunscreens. There have been suggestions, not strongly substantiated, that benzene may increase the risk for cancer, especially leukemias.

But there is sparse data on the absorption and toxicity of benzene exposure with sunscreen use. The data, he said, include an analysis of National Health and Nutrition Examination Survey data, which found that people who regularly used sunscreens were less likely to have elevated benzene levels compared with those who didn’t use sunscreens.

Turning to insecticides, Dr. Schachner discussed N,N-diethyl-m-toluamide (DEET), the active ingredient in many insect repellents. It helps avoid “some terrible diseases,” including mosquito-borne illnesses such as malaria and tick-borne conditions such as Lyme disease, and is available in several convenient formulations, he said.

When used on children, the American Academy of Pediatrics (AAP) recommends products with no more than 30% DEET. And insect repellents are not recommended for children younger than 2 months, or under clothing or damaged skin, he said.

Dr. Schachner referred to a case series of 18 children who developed DEET-induced encephalopathy; 13 (72%) involved dermal exposure. Three of those with cutaneous exposure died, mostly from neurologic, respiratory, and cardiac issues. “What’s very striking is that 55% of the kids were exposed to DEET of 20% or less, even though the AAP approves DEET at 30%, so maybe that’s something we have to look at,” he said.
 

Medication Patches

With medication patches, especially fentanyl transdermal patches, much can go wrong when it comes to children. This was highlighted by the cases Schachner cited, including an infant who developed acute cytotoxic cerebellar edema from fentanyl patch intoxication.

In another case, emergency room staff found a fentanyl patch stuck to the back of a 3-year-old girl. A CT scan showed global cerebral edema, and the patient progressed to brain death. “This is not a unique case; there have been over 10 such cases in the United States,” said Dr. Schachner. “We should be doing better with fentanyl.”

Nicotine patches can also be dangerous to children, he added. As for other topical agents, there have been reports of toxicity and deaths linked to salicylic acid, commonly used by dermatologists because of its bacteriostatic, fungicidal, keratolytic, and photoprotective properties.

Dr. Schachner cited the case of a 2-month-old where the pediatrician prescribed 50% salicylic acid for seborrheic dermatitis of the scalp, under occlusion. “It’s amazing this child survived; that’s clearly a physician error,” he said.

Henna, a reddish-brown dye derived from the crushed leaves of Lawsonia alba, is used cosmetically for the hair, skin, and nails. Many henna products are mixed with additives, including para-phenylenediamine, which has been associated with dermatitis, asthma, renal failure, and permanent vision loss.

Asked to comment on the presentation, Sheilagh Maguiness, MD, professor of dermatology and pediatrics and chair of pediatric dermatology at the University of Minnesota, Minneapolis, recalled a particularly concerning story in 2008, when the FDA issued a warning about Mommy’s Bliss, a cream containing chlorphenesin and phenoxyethanol as preservatives, promoted to nursing mothers for soothing cracked nipples. There were reports of the cream causing respiratory distress, vomiting, and diarrhea in nursing infants.

TORONTO — Lawrence A. Schachner, MD, would like pediatric dermatologists to adopt a “toxic agent of the year” to raise awareness about the potential harm related to certain topical treatments in babies and young children.

Dr. Schachner, director of the Division of Pediatric Dermatology in the Department of Dermatology & Cutaneous Surgery at the University of Miami, Coral Gables, Florida, said he got the idea from the American Contact Dermatitis Society, which annually names the “Allergen of the Year.”

In pediatric dermatology, the list of potentially toxic products includes topical analgesics such as Castellani paint used for skin infections, alcohols used for umbilical care in newborns, and henna dye used in cosmetics, said Dr. Schachner, professor of pediatrics and dermatology at the University of Miami.

“Any one of those would be excellent toxic substances of the year” that could be the focus of an educational campaign, he told this news organization following his presentation on “Toxicology of Topical Ingredients in Pediatric Dermatology” at the annual meeting of the Society for Pediatric Dermatology on July 14.

Hi. I’m Art Caplan. I’m at the Division of Medical Ethics at New York University Grossman School of Medicine in New York City. 

There are many things screwy with our healthcare system. Many of you [reading] this are dealing with bureaucracy, paperwork, all sorts of constraints, restraints, and requirements that sometimes make the practice of medicine, or even nursing, difficult.

I don’t think I’ve seen anything screwier, from a moral point of view, than the system we have that allows for preauthorization by third-party payers, or insurers, in order to give care to patients. It’s pretty clear that a third-party payer has a conflict of interest. It’s simple: They don’t want to spend money.

Their goal as profit-making companies is to reduce what it is that they’re going to authorize. That clearly is driving how the preauthorization process works. We’re not getting a neutral review by third parties of the appropriateness of treatment recommendations or somebody saying, this is the standard of care and this is what ought to happen.

We’re letting the people who have the pocketbooks and the wallets have prior approval of what the doctor thinks is correct. That is really not the way to practice medicine. 

We now have more evidence about what really is going on. A doctor was recently interviewed by ProPublica and said that she had worked for Cigna as a reviewer. Basically, the message she got from that insurer was to speed it up, go fast, and basically “deny, deny, deny” when she got requests. Those are her words, not mine.

We get a peek under the tent of how this works, and Dr. Day is basically saying she had to leave because she just didn’t feel that it was evidence-driven. It was driven by concerns about who’s going to lose money or make money.

If you want to check to see whether something is appropriate, the question becomes, who ought to do prior review? 

Who does it now? Sometimes doctors. Sometimes nurses who aren’t in the specialty where the request is coming in for preapproval. I’ve even seen situations where some companies use nurses in other countries, such as the Philippines, to do preapproval. They send them information, like a clip, to use to deny things that basically is boilerplate language, whatever the request is.

Looming up now, some insurers are starting to think, well, maybe artificial intelligence could do it. Just review the written request, trigger certain responses on the part of the artificial intelligence — it can deny the claims just as well as a human — and maybe it’s even cheaper to set up that system for the insurer.

This is ethically nuts. We need to have a system where doctors’ judgments drive what patients get. You listen to doctors, as I do, about preapproval access and they say patients sometimes give up trying to get what they think is needed. Continuity of care is interrupted if they have to keep making requests all the time.

There are adverse events when the thing that the doctor thought was most appropriate isn’t approved and something else is used that is less safe or less efficacious. It isn’t in patient interest to have the person with the wallet saying, this is what we think you need, and then having unqualified people or even automated intelligence with no accountability and no transparency get involved in preauthorization.

This system costs us money because middlemen are doing all this work. It basically becomes one of the huge scandals, in my view, of our health system, that doctors don’t ultimately decide what the patient needs. A preauthorizing third party or robot, without transparency, without accountability, and behind closed doors second-guesses what’s going on.

A recent survey by the Pew Research Center has found that among adults younger than 50, the percentage who say they are unlikely to have children rose from 37% to 47%. With this trend freshly etched in my consciousness, I stumbled across an interview with Anastasia Berg, an assistant professor of philosophy at the University of California, Irvine. Professor Berg and Rachel Wiseman have just published What Are Children For? On Ambivalence and Choice. How could a pediatrician with time on his hands ignore a provocative title like that?

I was immediately drawn to Professor Berg’s observations about the “concerns, anxieties, and lines of reasoning people encounter when considering whether or not they should have children.” Prior to the 1960s, motherhood seemed to just be a natural progression from marriage. That’s the way my wife and I approached it when we had our first child while I was in my last year of medical school in 1971. There was no discussion of the pros and cons, except maybe that financially waiting until the eve of my first professional paycheck seemed to make sense.

However, as Professor Berg points out, from the 1960s up until well into the 1980s, as feminist thought gained a higher profile, there were anti-motherhood factions. There were others who wanted to see motherhood reformed and adapted so it “could once again be a legitimate source of meaning and value in life.” However, both camps agreed that the choice to have children was a decision that “women should make completely on their own.”

Now, well into the new millennium, we are looking at a completely different landscape. In the past, having children was woven into the fabric of human life in which we had a past, a present, and a role in creating the future. Professor Berg observes that currently, having children is often considered a project, not unlike our other projects such as “career choice or travel plans.” What are the pluses and minuses?

The Pew Survey found that 60% of adults younger than 50 who don’t have children said that not having children made it less difficult to be successful and have an active social life. Many felt that being a parent would improve the chances of having someone to care for you as you aged.

When my wife and I considered the financial costs of motherhood more than 50 years ago, our calculation was primarily about the timing. The decision to have a second child focused our concern around our ability to balance our attention between two siblings. A third child just sorta happened without any discussion.

Professor Berg echoes the Pew findings when she observes that currently woman are considering the cost in terms of their identities. Will motherhood transform me? Will there be a cost not only to my career but also to all the associations, interests, and activities I have accumulated? These costs are likely to be greater the longer the decision to have a child is put off. She adds that viewing motherhood as a transformation can make the decision to have children scarier than it needs to be. My wife and I, at age 26 and 27, were still in the early stages of building our identities. My wife had a 2-year college degree and no career plans on the horizon. Having a child was one of those things that was built into who we became.

But to compare our experiences in the 1970s to the realities of the first quarter of the 21st century ignores the concerns facing today’s adults who are facing the cloud of uncertainty hanging over all of us. Despite their claims to fix the situation, both sides of the political spectrum are leveraging fear to gain our support. Even climate change skeptics must have some concern in the spate of natural disasters we are experiencing. Not to mention the pandemic. Anxiety in this country is at an all time high. Optimism doesn’t seem to fit into today’s journalists’ lexicon, as they chose to focus on conflict instead of cooperation. It’s hard to question any adult who harbors serious doubts on taking on the challenge of parenthood and bringing a child into a world that feels unsettled.

However, based on her research and her own experience as a parent, Professor Berg offers some advice. She encourages people to think and discuss the decision to have children earlier in their life trajectory, before they have made decisions that may eventually limit their options. Second, she discourages making a list of pros and cons. Finally, she advises taking a long view and ask yourself whether you “choose to take a direct part in ushering in the next generation.”

Sounds like advice that will optimize the chances of making the good decision about having a child. I’m just thankful to have lived at time and in a situation when having child was just the thing most married couples did.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Will there be a cost not only to my career but also to all the associations, interests, and activities I have accumulated? These costs are likely to be greater the longer the decision to have a child is put off. She adds that viewing motherhood as a transformation can make the decision to have children scarier than it needs to be. My wife and I, at age 26 and 27, were still in the early stages of building our identities. My wife had a 2-year college degree and no career plans on the horizon. Having a child was one of those things that was built into who we became.

But to compare our experiences in the 1970s to the realities of the first quarter of the 21st century ignores the concerns facing today’s adults who are facing the cloud of uncertainty hanging over all of us. Despite their claims to fix the situation, both sides of the political spectrum are leveraging fear to gain our support. Even climate change skeptics must have some concern in the spate of natural disasters we are experiencing. Not to mention the pandemic. Anxiety in this country is at an all time high. Optimism doesn’t seem to fit into today’s journalists’ lexicon, as they chose to focus on conflict instead of cooperation. It’s hard to question any adult who harbors serious doubts on taking on the challenge of parenthood and bringing a child into a world that feels unsettled.

However, based on her research and her own experience as a parent, Professor Berg offers some advice. She encourages people to think and discuss the decision to have children earlier in their life trajectory, before they have made decisions that may eventually limit their options. Second, she discourages making a list of pros and cons. Finally, she advises taking a long view and ask yourself whether you “choose to take a direct part in ushering in the next generation.”

Sounds like advice that will optimize the chances of making the good decision about having a child. I’m just thankful to have lived at time and in a situation when having child was just the thing most married couples did.

A recent survey by the Pew Research Center has found that among adults younger than 50, the percentage who say they are unlikely to have children rose from 37% to 47%. With this trend freshly etched in my consciousness, I stumbled across an interview with Anastasia Berg, an assistant professor of philosophy at the University of California, Irvine. Professor Berg and Rachel Wiseman have just published What Are Children For? On Ambivalence and Choice. How could a pediatrician with time on his hands ignore a provocative title like that?

I was immediately drawn to Professor Berg’s observations about the “concerns, anxieties, and lines of reasoning people encounter when considering whether or not they should have children.” Prior to the 1960s, motherhood seemed to just be a natural progression from marriage. That’s the way my wife and I approached it when we had our first child while I was in my last year of medical school in 1971. There was no discussion of the pros and cons, except maybe that financially waiting until the eve of my first professional paycheck seemed to make sense.

However, as Professor Berg points out, from the 1960s up until well into the 1980s, as feminist thought gained a higher profile, there were anti-motherhood factions. There were others who wanted to see motherhood reformed and adapted so it “could once again be a legitimate source of meaning and value in life.” However, both camps agreed that the choice to have children was a decision that “women should make completely on their own.”

Now, well into the new millennium, we are looking at a completely different landscape. In the past, having children was woven into the fabric of human life in which we had a past, a present, and a role in creating the future. Professor Berg observes that currently, having children is often considered a project, not unlike our other projects such as “career choice or travel plans.” What are the pluses and minuses?

The Pew Survey found that 60% of adults younger than 50 who don’t have children said that not having children made it less difficult to be successful and have an active social life. Many felt that being a parent would improve the chances of having someone to care for you as you aged.

When my wife and I considered the financial costs of motherhood more than 50 years ago, our calculation was primarily about the timing. The decision to have a second child focused our concern around our ability to balance our attention between two siblings. A third child just sorta happened without any discussion.

Geographic spread of the ticks that most often cause Lyme disease in the United States and a rise in incidence of bites, resulting in 476,000 new US cases a year, have increased the chances that physicians who have never encountered a patient with Lyme disease will see their first cases.

“It’s increasing in areas where it was not seen before,” Steven E. Schutzer, MD, with the Department of Medicine, Rutgers New Jersey Medical School, Newark, said in an interview. Dr. Schutzer coauthored a report on diagnosing and treating Lyme disease with Patricia K. Coyle, MD, Department of Neurology, Renaissance School of Medicine at Stony Brook University, Stony Brook, New York.

The report, a Curbside Consult published in New England Journal of Medicine Evidence, comes amid high season for Lyme disease. Bites from an ixodid (hard shield) tick — almost always the source of the disease in the United States — are most common from April through October.

Identifying the Bite

About 70%-90% of the time, Lyme disease will be signaled by erythema migrans (EM) or lesion expanding from the tick bite site, the authors wrote. The “classic” presentation looks like a bullseye, but most of the time the skin will show a variation of that, the authors noted.

“The presence of EM is considered the best clinical diagnostic marker for Lyme disease,” they wrote.

Other dermatologic conditions, however, can complicate diagnosis: “EM mimickers include contact dermatitis, other arthropod bites, fixed drug eruptions, granuloma annulare, cellulitis, dermatophytosis, and systemic lupus erythematosus,” they wrote.
 

Testing Steps

“The current recommendation is to do two-step testing almost simultaneously,” Dr. Schutzer said in an interview. The first, he said, is an ELISA (enzyme-linked immunosorbent assay)-type test and the second one, used for years, has been a pictoral view of a Western immunoblot showing which antigens of the Lyme bacteria, Borrelia burgdorferi, the antibodies are reacting to.

However, the pictoral view is subjective and some of the antigens could be cross-reactive. So the U.S. Food and Drug Administration (FDA) “has been allowing newer substitutes like a second ELISA-like assay that often uses more recombinant, less cross-reactive antigen targets,” he said. The authors advised that, “The second-tier test should not be performed alone without the first tier.”

Dr. Schutzer advised physicians to check with the lab they plan to use before sending samples.

“If you’re a practicing physician and you know you’re using a particular laboratory, you should familiarize yourself with them, talking to one of the clinical pathologists involved in advance to know what the limitations are.” Take the time to talk with the person overseeing the test and get tips on how they want the sample transported and how the cases should be reported, he said.

If the patient has neurological symptoms, he said, before treating talk with a neurologist who can advise whether, for instance, a spinal tap is in order or whether an emergency department visit is appropriate.

“If you just start proceeding you may mess up the diagnostic signs that could show up in a lab test. Don’t be hesitant to ask for extra input from colleagues,” Dr. Schutzer said.
 

Suspicion in Endemic Areas

On Long Island, New York, where Lyme disease is endemic, internist Ian Storch, DO, said he sees “a few cases a season.

“We have a lot of people over the summer going to the Hamptons and areas out east for the weekend and tick bites are not uncommon,” he said. “People panic.”

He said one thing it’s important to tell patients is that the tick has to be on the skin for 48-72 hours to transmit the disease. If individuals were in a wooded area and were fine before they got there and the tick was attached for less than 2 days, “they’re usually fine.”

Another issue, Dr. Storch said, is patients sometimes want to get tested for Lyme disease immediately after a tick bite. But the antibody test doesn’t turn positive for weeks, he noted, and you can get a false-negative result. “If you’re worried and you really want to test, you need to wait 6 weeks to do the blood test.”

In his region, he said that although a tick bite is a red flag, he may also suspect Lyme disease when a patient presents with otherwise unexplained joint pain, weakness, lethargy, or fever. “In our area, those are things that would make you test for Lyme.”

He also urged consideration of Lyme in this new age of long COVID. Weakness, fatigue, and lethargy are also classic symptoms of long COVID, he noted. “Keep Lyme disease in your differential because there is a lot of overlap with chronic Lyme disease,” Dr. Storch said.

Discerning Lyme from Southern Tick–Associated Rash Illness

Bonnie M. Word, MD, director of the Houston Travel Medicine Clinic in Texas, where Lyme disease is not endemic, said Lyme disease “will not and should not be on the initial differential diagnosis for those residing in nonendemic areas unless a history of travel to an endemic area is obtained.”

She noted the typical EM rash may not be as distinct or easy to discern on black and brown skin. In addition, she said, EM may have many variations in presentation, such as a crusted center or faint borders, which could lead to a delay in diagnosis and treatment. She suggested consulting the CDC guidance on Lyme disease rashes.

Another challenge in diagnosis, she said, is the patient who presents with what appears to be a classic EM lesion but does not live in a Lyme-endemic area. In Texas, Southern Tick–Associated Rash Illness (STARI) may present with a similar lesion, she said.

“It is transmitted by the Lone Star Tick, which is found in the southeast and south-central US,” Dr. Word said. “However, its habitat is moving northward and westerly,” she said.

Adding Lyme disease to the differential diagnosis is reasonable, she said, if a patient presents with neurologic symptoms “such as a facial palsy, meningitis, radiculitis, and carditis if in addition to their symptoms there is evidence of an epidemiologic link to a Lyme-endemic region.”

She noted that a detailed travel history is important as “Lyme is also endemic in Eastern Canada, Europe, states of the former Soviet Union, China, Mongolia, and Japan.”

Primary care physicians play a critical role in evaluating, diagnosing, and treating most cases of early Lyme disease, thus limiting the number of people who will develop disseminated or late Lyme disease, she said. “The two latter manifestations are most often treated by infectious disease, neurology, or rheumatology specialists.”

Treatment* 

Treatment is tailored to the clinical situation, Dr. Schutzer and Dr. Coyle write. A watch-and-wait approach may be appropriate in an asymptomatic but concerned person, even in an endemic area if the person has no known tick bite and no EM lesion.

If there is high risk of an infected ixodid tick bite in a high-incidence area and the tick was attached for at least 36 hours but less than 72 hours, one dose of doxycycline has been recommended as prophylaxis.

When a diagnosis of early nondisseminated Lyme disease is made after observation  of an EM lesion, oral antibiotics are typically used to treat for 10 to 14 days. Suggested oral antibiotics and doses are 100 mg of doxycycline twice a day, 500 mg of amoxicillin three times a day, or 500 mg of cefuroxime twice a day, the authors write.

Dr. Schutzer said he hopes the paper serves as a refresher for those physicians who regularly see Lyme disease cases and also helps those newly included in the disease’s spreading regions.

“The earlier you diagnose it, the earlier you can treat it and the better the chance for a favorable outcome,” he said.

Dr. Schutzer, Dr. Coyle, Dr. Storch, and Dr. Word reported no relevant financial relationships.

Newborn screening for neonatal vitamin B12 deficiency may lead to a fourfold reduction in chances of developing symptomatic vitamin B12 in the first year of life compared with infants without newborn screening, a hospital-based surveillance study in Germany indicates.

Vitamin B12 deficiency can impede development in infants, but the true impact of newborn screening versus no screening had not been known in Germany. Early treatment had been shown to be linked with normal development in infants who got newborn screening, but left unclear was how many who had newborn screening would have progressed to symptomatic vitamin B12 deficiency without treatment. Thus formal evidence for the benefit of the screening was lacking.

The nationwide surveillance study, led by Ulrike Mütze, MD, with the Heidelberg University Center for Child and Adolescent Medicine, was published online in Pediatrics. It used prospectively collected data from incident cases of infants under 12 months of age with vitamin B12 deficiency from 2021 to 2022.

The researchers analyzed 61 cases of vitamin B12 deficiency reported to the German Pediatric Surveillance Unit. They were either identified by newborn screening (n = 31) or diagnosed after the onset of suggestive symptoms (non-newborn screening; n = 30).

At a median 4 months of age, the great majority (90%) of the infants identified by newborn screening were still asymptomatic, while the non-newborn screening cohort presented with muscular hypotonia (68%), anemia (58%), developmental delay (44%), microcephalia (30%), and seizures (12%).

Symptomatically diagnosed vitamin B12 deficiency in the baby’s first year was reported four times more frequently in infants who did not receive newborn screening for neonatal vitamin B12 deficiency compared with those screened for vitamin B12 as newborns (Fisher’s Exact Test; odds ratio, 4.12 [95% confidence interval, 1.29-17.18], P = .008).

Clinical presentation of vitamin B12 deficiency in infants usually starts in the first months and reportedly includes, in addition to developmental delay, feeding difficulties, muscular hypotonia and weakness, severe failure to thrive, irritability, lethargy, and (as late symptoms) megaloblastic anemia and brain atrophy.

The current study confirmed these reports and highlighted that the most common presentations in symptomatic infantile vitamin B12 deficiency were muscular hypotonia, anemia, developmental delay, malnutrition or failure to thrive, and microcephalia, brain atrophy, or delayed myelination.

Stephen Walker, MD, a pediatric neurologist at University of Alabama, Birmingham, who was not involved with the study, said newborn screening for vitamin B12 deficiency is routine in the United States.

“In Alabama, we’re generally the last to adopt any of these newborn screenings ... and we’ve been doing it for several years,” he said. Vitamin B12 deficiency is one of 59 conditions included in the state’s newborn blood spot screening. In the United States, he added, when deficiencies are identified, cases are quickly referred to genetic or nutritional specialists.

In the Mütze et al. study, the authors conclude, “The incidence of symptomatic vitamin B12 deficiency accounts for about half of the estimated incidence of the vitamin B12 deficiency identified by newborn screening [NBS]. This supports the notion that not all newborns identified will develop a symptomatic infantile vitamin B12 deficiency but at the same time [this study demonstrates] the high beneficial potential of NBS for vitamin B12 deficiency.”

Dr. Mütze received a research grant from the Medical Faculty of Heidelberg University, Germany. Dr. Kölker, Dr. Hoffmann, and Dr. Mütze received research grants for their work on newborn screening from the Dietmar Hopp Foundation, St. Leon-Rot, Germany. Dr. Hoffmann, Dr. Janzen, and Dr. Röschinger are principal investigators for newborn screening pilot studies including neonatal vitamin B12 deficiency. The other authors have no relevant disclosures. Dr. Walker reports no relevant financial relationships.

It used prospectively collected data from incident cases of infants under 12 months of age with vitamin B12 deficiency from 2021 to 2022.

The researchers analyzed 61 cases of vitamin B12 deficiency reported to the German Pediatric Surveillance Unit. They were either identified by newborn screening (n = 31) or diagnosed after the onset of suggestive symptoms (non-newborn screening; n = 30).

At a median 4 months of age, the great majority (90%) of the infants identified by newborn screening were still asymptomatic, while the non-newborn screening cohort presented with muscular hypotonia (68%), anemia (58%), developmental delay (44%), microcephalia (30%), and seizures (12%).

Symptomatically diagnosed vitamin B12 deficiency in the baby’s first year was reported four times more frequently in infants who did not receive newborn screening for neonatal vitamin B12 deficiency compared with those screened for vitamin B12 as newborns (Fisher’s Exact Test; odds ratio, 4.12 [95% confidence interval, 1.29-17.18], P = .008).

Clinical presentation of vitamin B12 deficiency in infants usually starts in the first months and reportedly includes, in addition to developmental delay, feeding difficulties, muscular hypotonia and weakness, severe failure to thrive, irritability, lethargy, and (as late symptoms) megaloblastic anemia and brain atrophy.

The current study confirmed these reports and highlighted that the most common presentations in symptomatic infantile vitamin B12 deficiency were muscular hypotonia, anemia, developmental delay, malnutrition or failure to thrive, and microcephalia, brain atrophy, or delayed myelination.

Stephen Walker, MD, a pediatric neurologist at University of Alabama, Birmingham, who was not involved with the study, said newborn screening for vitamin B12 deficiency is routine in the United States.

“In Alabama, we’re generally the last to adopt any of these newborn screenings ... and we’ve been doing it for several years,” he said. Vitamin B12 deficiency is one of 59 conditions included in the state’s newborn blood spot screening. In the United States, he added, when deficiencies are identified, cases are quickly referred to genetic or nutritional specialists.

In the Mütze et al. study, the authors conclude, “The incidence of symptomatic vitamin B12 deficiency accounts for about half of the estimated incidence of the vitamin B12 deficiency identified by newborn screening [NBS]. This supports the notion that not all newborns identified will develop a symptomatic infantile vitamin B12 deficiency but at the same time [this study demonstrates] the high beneficial potential of NBS for vitamin B12 deficiency.”

Dr. Mütze received a research grant from the Medical Faculty of Heidelberg University, Germany. Dr. Kölker, Dr. Hoffmann, and Dr. Mütze received research grants for their work on newborn screening from the Dietmar Hopp Foundation, St. Leon-Rot, Germany.

Dr. Walker reports no relevant financial relationships.

Newborn screening for neonatal vitamin B12 deficiency may lead to a fourfold reduction in chances of developing symptomatic vitamin B12 in the first year of life compared with infants without newborn screening, a hospital-based surveillance study in Germany indicates.

Vitamin B12 deficiency can impede development in infants, but the true impact of newborn screening versus no screening had not been known in Germany. Early treatment had been shown to be linked with normal development in infants who got newborn screening, but left unclear was how many who had newborn screening would have progressed to symptomatic vitamin B12 deficiency without treatment. Thus formal evidence for the benefit of the screening was lacking.

Among patients who presented to a combined pediatric rheumatology/dermatology clinic (RDC) at the University of California, San Francisco (UCSF), 24% presented without a confirmed diagnosis, and only 41% received a diagnosis during their first clinic visit, results from a retrospective cohort study showed.

“This finding highlights the complexity of patients referred to this clinic,” the study’s first author, Jessica Crockett, a fourth-year medical student at UCSF, told this news organization following the annual meeting of the Society for Pediatric Dermatology, where the study was presented during a poster session. “Integrated care models such as rheumatology/dermatology clinics (RDCs) have been shown to facilitate complete clinical evaluations, establish new or revised diagnoses, and streamline care for adult patients with complex autoimmune skin diseases. However, few pediatric RDCs exist nationwide, and data therefore is quite limited.”

To advance the understanding of pediatric RDC practice patterns, the influence of the care model on patient care, and professional development for trainees and clinicians, Ms. Crockett collaborated with senior author Kelly Cordoro, MD, professor of dermatology and pediatrics at UCSF, and colleagues to evaluate a cohort of 71 patients who received care at the UCSF pediatric RDC. The clinic, which was launched in 2017, includes two dermatologists, two rheumatologists, trainees, a social worker, and a nurse. Team members participate in a preclinic conference to review patient data and images, discuss relevant literature, and develop an approach to each patient.

In a separate part of the study, the researchers distributed a survey to 17 pediatric dermatologists who participate in unique RDCs in North America. Respondents were asked to describe the variability of clinical operations, participants, administrative/clinical support, and educational value for participating physicians and trainees.

Of the 71 patients cared for at the UCSF pediatric RDC, 69% were female, 44% were White, 51% were aged 13-21 years, 42% were aged 3-12 years, and 7% were aged 0-11 years at their first clinic visit. The top four primary RDC diagnoses were linear morphea (33%), lupus (23%), psoriasis (13%), and juvenile dermatomyositis (10%).

Nearly one in four patients (17, or 24%) presented to the RDC without a confirmed diagnosis. A diagnosis was established at the first RDC visit for 7 of these 17 patients (41%). Among 54 patients who presented with an established diagnosis, the first RDC visit confirmed the diagnosis for 52 (96%) and revised it for 2 (4%). “Initial pediatric RDC evaluation significantly influenced patient care by confirming or revising preexisting diagnoses, rendering new diagnoses, and streamlining additional laboratory and imaging recommendations,” the researchers wrote in their poster.

The evaluation also resulted in modified disease management in the form of systemic medication changes or dosage adjustments as well as the initiation of novel therapies. For example, systemic medication changes were made during the first RDC visit in 34 of the 46 patients (74%) who were on systemic medication at presentation.

“Seeing complex patients together in real time allows specialists and other team members (social work, nursing, PT/OT, for example) to share ideas, communicate clearly to families, and efficiently develop recommendations,” Ms. Crockett said of the UCSF pediatric RDC. “Exposure to other specialists while caring for patients enhances medical knowledge, communication skills, and professional competency of faculty and trainees alike.”

In the survey portion of the study, each of the 17 dermatologists reported that the pediatric RDC is valuable for patient care, and 88% believed the RDC was a valuable use of their time. However, only 59% of respondents reported having administrative support, and only 29% had a dedicated clinic coordinator or navigator.

“We were surprised to find that only a quarter of pediatric RDCs incorporate an educational conference,” Dr. Cordoro told this news organization. “We have found that assembling the care team prior to seeing patients to review clinical data, discuss relevant literature, and define the clinical questions for each patient is an integral part of the clinical operation. The trainees are involved in these conference presentations, and it really enhances their understanding of the complex diagnoses we manage in this clinic and the issues faced by affected children and families. The preclinical conference increases efficiency, positively influences patient care, and supports professional development for all participants.”

The study was indirectly supported by a fellowship grant awarded to Ms. Crockett from the Pediatric Dermatology Research Alliance. The researchers reported having no relevant disclosures.

When Black, Hispanic, and American Indian/Alaska Native parents or guardians were asked about barriers and facilitators to accessing pediatric dermatology care for their children, a theme emerged that surprised lead study author Lucinda L. Kohn, MD, MHS.

“Most families said that racial concordance didn’t matter that much, but they did place high value on being heard,” Dr. Kohn, of the Department of Dermatology at the University of Colorado, Aurora, told this news organization following the Society for Pediatric Dermatology annual meeting, where the study was presented during a poster session. “Being heard means that their experience was respected; that their questions and worries were anticipated, addressed, and answered; and that their feelings were acknowledged.”

Dr. Kohn

As a way to understand these families’ knowledge, attitudes, and beliefs about access to pediatric dermatology care and how the hospital system and medical team could better support them, Dr. Kohn and colleagues conducted in-depth, semi-structured interviews with 32 English-speaking parents and/or guardians of children who received care at the Children’s Hospital Colorado Anschutz Medical Campus pediatric dermatology clinic. The researchers conducted and recorded the 30- to 60-minute interviews via Zoom or phone call from October 17, 2023, to January 23, 2024. Domains of interest included participant background and experiences, communication preferences, and experience accessing pediatric dermatology care. Next, Dr. Kohn and colleagues used a reflexive, team-based inductive approach to carry out a thematic analysis from the interviews.

The mean age of the 32 study participants was 38.9 years; 14 (43.75%) identified as Hispanic, 11 (34.38%) as Black, and 12 (37.50%) as American Indian/Alaska Native (response categories were not mutually exclusive). Several themes emerged from analysis of the interviews. Barriers to receiving pediatric dermatology care included distrust of the healthcare system, generational and community lack of awareness about dermatology, distance to the hospital, and household income.

“One family mentioned that they needed to save up for 3 months to be able to afford the drive, hotel, and food needed for their child to attend their pediatric dermatology visit,” Dr. Kohn said. “As we know, most pediatric dermatology visits are 10-15 minutes long, so that they needed to cut groceries for 3 months to be able to see a pediatric dermatologist for 10-15 minutes is just heart wrenching. Families also didn’t understand the large teams that we have in medicine: The medical students, residents, nurses, medical assistants, attendings, and physician extenders.”

One key facilitator to receiving pediatric dermatology care was the family’s perception that the provider shares their minoritized experience because of similarities in skin tone. “When it’s your own race, whether it’s Black, Hispanic, or you know, we feel like when it’s someone like me, they will look out for me more,” one study participant said. Other facilitators expressed by the study participants included increased representation from the family’s community at all levels of healthcare (“the more you see providers and people in a space that look like you, I think the more welcoming it will feel,” one said) and normalizing dermatology care (“letting it be known that going to the dermatologist is just like going to a regular doctor,” another said).

Dr. Kohn acknowledged certain limitations of the study, including its single-center qualitative design. “Qualitative studies are not generalizable, but they do dive into the lived experiences of a few,” she said. “There aren’t a lot of qualitative studies in derm, so even though this was a very simple study, we hope the findings will help us to support our most diverse and underserved families access the pediatric dermatology care that they need.”

The researchers reported having no relevant financial disclosures. The study was recognized as an award-winning poster at the meeting.

Colchicine is an effective treatment for most pediatric patients with complex aphthous stomatitis (CAS), results from a small retrospective study showed.

“Complex aphthous stomatitis in children is typically treated with topical supportive care, which is often not effective,” one of the study investigators, Ananya Shah, a third-year medical student at the University of Rochester School of Medicine & Dentistry, Rochester, New York, told this news organization following the Society for Pediatric Dermatology annual meeting, where the study was presented during a poster session. “There is limited research on CAS and its treatment in children. Colchicine is often used for treatment of CAS in adults, but its use in children has not been studied.”

Ms. Shah, in collaboration with Hilary Kunkel, MD, Nessa Aghazadeh, MD, and Megha Tollefson, MD, of the Department of Dermatology, Mayo Clinic, Rochester, Minnesota, retrospectively reviewed the charts of 20 children diagnosed with CAS who were treated with colchicine, an anti-inflammatory drug often used to treat gout, at the clinic between 2000 and 2023. Treatment responses were defined as no response, partial response, and complete response. Half of the patients were girls, and their median age at presentation was 5 years.

Ulcers were most commonly located in the buccal mucosa (80%), followed by the gingiva (50%), the mucosal lip (50%), and the palate (40%). Nearly all patients (95%) reported that the CAS caused difficulties with eating or drinking. Other effects on their quality of life included weight loss (35%), bleeding (30%), and difficulty brushing teeth (25%). “I was surprised by how much CAS impacts pediatric patients’ quality of life,” Ms. Shah said. “Almost all of the patients experienced trouble with basic activities of daily living, including eating and drinking. In addition, CAS negatively impacted mental health and led to missed school for patients.”

The researchers had follow-up data on responses to colchicine for 14 of the 20 patients. Of these, 12 (86%) had symptom improvement, 5 (36%) had a complete response, 8 (57%) had a partial response, and 1 (7%) did not respond. Nine patients (64%) experienced side effects. Of these, six had diarrhea, two had nausea, and one had constipation.

“Colchicine should be considered as a treatment in pediatric patients who have refractory complex aphthous stomatitis as it is generally well tolerated with minimal side effects,” Ms. Shah said. She acknowledged certain limitations of the study, including its single-center, retrospective design.

The researchers reported having no relevant disclosures.

Treatment responses were defined as no response, partial response, and complete response. Half of the patients were girls, and their median age at presentation was 5 years.

Ulcers were most commonly located in the buccal mucosa (80%), followed by the gingiva (50%), the mucosal lip (50%), and the palate (40%). Nearly all patients (95%) reported that the CAS caused difficulties with eating or drinking. Other effects on their quality of life included weight loss (35%), bleeding (30%), and difficulty brushing teeth (25%). “I was surprised by how much CAS impacts pediatric patients’ quality of life,” Ms. Shah said. “Almost all of the patients experienced trouble with basic activities of daily living, including eating and drinking. In addition, CAS negatively impacted mental health and led to missed school for patients.”

The researchers had follow-up data on responses to colchicine for 14 of the 20 patients. Of these, 12 (86%) had symptom improvement, 5 (36%) had a complete response, 8 (57%) had a partial response, and 1 (7%) did not respond. Nine patients (64%) experienced side effects. Of these, six had diarrhea, two had nausea, and one had constipation.

“Colchicine should be considered as a treatment in pediatric patients who have refractory complex aphthous stomatitis as it is generally well tolerated with minimal side effects,” Ms. Shah said. She acknowledged certain limitations of the study, including its single-center, retrospective design.

The researchers reported having no relevant disclosures.

Colchicine is an effective treatment for most pediatric patients with complex aphthous stomatitis (CAS), results from a small retrospective study showed.

“Complex aphthous stomatitis in children is typically treated with topical supportive care, which is often not effective,” one of the study investigators, Ananya Shah, a third-year medical student at the University of Rochester School of Medicine & Dentistry, Rochester, New York, told this news organization following the Society for Pediatric Dermatology annual meeting, where the study was presented during a poster session. “There is limited research on CAS and its treatment in children. Colchicine is often used for treatment of CAS in adults, but its use in children has not been studied.”
