Epidermoid cysts are asymptomatic, well-circumscribed, mobile, subcutaneous masses that elevate the skin. Also known as epidermal, keratin, or infundibular cysts, epidermoid cysts are caused by proliferation of surface epidermoid cells within the dermis and can arise anywhere on the body, most commonly on the face, neck, and trunk.¹ Cutaneous cysts often contain fluid or semifluid contents and can be aesthetically displeasing or cause mild pain, prompting patients to seek removal. Definitive treatment of epidermoid cysts is complete surgical removal,² which can be performed in office in a sterile or clean manner by either dermatologists or primary care providers.

Prior to incision, a local anesthetic—commonly lidocaine with epinephrine—is injected in the region surrounding the cyst sac so as not to rupture the cyst wall. Maintaining the cyst wall throughout the procedure ensures total cyst removal and minimizes the risk for recurrence. However, it often is difficult to approximate the cyst border because it cannot be visualized prior to incision.

Throughout the duration of the procedure, cyst contents may suddenly spray out of the area and pose a risk to providers and their staff (Figure, A). Even with careful application around the periphery, either puncture or ­pericystic anesthesia between the cyst wall and the dermis can lead to splatter. Larger and wider peripheral anesthesia may not be possible given a shortage of ­lidocaine and a desire to minimize injection. Even with meticulous use of personal protective equipment in cutaneous surgery, infectious organisms found in ruptured cysts and abscesses may spray the surgical field.³ Therefore, it is in our best interest to minimize the trajectory of cyst spray contents.

The Tools

We have employed 2 simple techniques using equipment normally found on a standard surgical tray for easy safe injection of cysts. Supplies needed include 4×4-inch gauze pads, alcohol and chlorhexidine, a marker, all instruments necessary for cyst excision, and a small clear biohazard bag.

The Technique

Prior to covering the cyst, care is taken to locate the cyst opening. At times, a comedo or punctum can be seen overlying the cyst bulge. We mark the lumen and cyst opening with a surgical marker. If the pore is not easily identified, we draw an 8-mm circle around the mound of the cyst. 

One option is to apply a gauze pad over the cyst to allow for stabilization of the surgical field and blanket the area from splatter (Figure, B). Then we cover the cyst using antiseptic-soaked gauze as a protective barrier to avoid potentially contaminated spray. This tool can be constructed from a 4×4-inch gauze pad with the addition of alcohol and chlorhexidine. When the cyst is covered, the surgeon can inject the lesion and surrounding tissue without biohazard splatter.

Practice Implications

Outpatient surgical excision is a common effective procedure for epidermoid cysts. However, it is not uncommon for cyst contents to spray during the injection of anesthetic, posing a nuisance to the surgeon, health care staff, and patient. The technique of covering the lesion with antiseptic-soaked gauze or a small clear biohazard bag prevents cyst contents from spraying and reduces risk for contamination. In addition to these protective benefits, the use of readily available items replaces the need to order a splatter control shield.

Limitations—Although we seldom see spray using our technique, covering the cyst with gauze may disguise the region of interest and interfere with accurate incision. Marking the lesion prior to anesthesia administration or using a clear biohazard bag minimizes difficulty visualizing the cyst opening.

Children with asthma who were insured by Medicaid were significantly less likely to receive specialist care over a 1-year period than children with private insurance, based on claims data from nearly 200,000 children.

Primary care clinicians successfully manage many children with asthma, but data on specialist care according to insurance coverage are lacking, wrote Kimberley H. Geissler, PhD, of the University of Massachusetts Chan Medical School–Baystate, Springfield, Massachusetts, and colleagues.

Despite many interventions over time, “low-income children insured by Medicaid, many of whom are from minoritized racial and ethnic groups, continue to have worse outcomes and higher rates of poorly controlled asthma than children who are privately insured,” Dr. Geissler said in an interview.

“Because differences in whether a child sees an asthma specialist could contribute to these disparities, better understanding specialist use among both groups of kids may help inform potential solutions,” she said.

In a study published in JAMA Network Open, the researchers identified children with asthma aged 2-17 years using data from the Massachusetts All-Payer Claims Database for the years 2015-2020. The study population included 198,101 children and 432,455 child-year observations from children with asthma during a year when they met at least one of three criteria with any asthma diagnosis: One or more hospital visits, two or more outpatient visits, or at least one outpatient visit and at least one asthma medication.
 

Outpatient Visit Outcome

The primary outcome of asthma specialist care was defined as at least one outpatient visit with any asthma diagnosis to a clinician with a code of allergy and immunology, pulmonology, or otolaryngology.

A total of 66.2% of the child-year observations involved Medicaid and 33.8% involved private insurance. Approximately 15% of the children received asthma specialist care. However, nearly twice as many children with private insurance received asthma specialty care compared with those with Medicaid (20.6% vs 11.9%). In a full logistic regression analysis, children with Medicaid insurance were 55% less likely to receive asthma specialist treatment than children with private insurance.

Allergy and immunology was the most common specialty used, and the child-years for this specialty among children with Medicaid were less than half of those among children with private insurance (7.1% vs 15.9%).

Rates of persistent asthma were 20.0% and 16.9% in children with Medicaid and private insurance, respectively. Overall, children with persistent asthma were nearly four times as likely to receive asthma specialist care (adjusted odds ratio, 3.96). However, the difference in odds of receiving specialty care based on insurance type in favor of private insurance was greater among children with persistent asthma than among those without persistent asthma (−24.0 percentage points vs −20.8 percentage points).

The researchers found a similar pattern of difference in asthma specialty care in a sensitivity analysis limiting the results to child-year observations with at least one outpatient visit with any asthma diagnosis in a calendar year, although they also found a slight narrowing of the difference between the groups over time.

“Contrary to expectations, disparities in specialist care by insurance type were even more striking in children with persistent asthma,” the researchers wrote in their discussion. Notably, the growth of specialty drugs such as biologics for moderate to severe asthma are mainly prescribed by specialists, and ensuring access to specialists for children with Medicaid may reduce disparities in asthma control for those with severe or poorly controlled disease, they added.

The study findings were limited by several factors including the use only of data from Massachusetts, which may not generalize to other states, and the use of completed specialist visits without data on referrals, the researchers noted. Other limitations included a lack of data on asthma symptom frequency or control and on the setting in which an asthma diagnosis was made.

However, the results suggest a need for more attention to disparities in asthma care by insurance type, and more research is needed to determine whether these disparities persist in subsets of children with asthma, such as those with allergies or chronic medical conditions, they concluded.
 

Takeaways and Next Steps

“Perhaps unsurprisingly, children with private insurance were more likely to receive asthma specialist care than children with Medicaid,” Dr. Geissler told this news organization. The researchers expected a smaller gap between insurance types among children with persistent asthma, a marker for asthma severity, she said. However, “we found that the gap between those with Medicaid and those with private insurance is actually larger” for children with persistent asthma, she added.

As improved treatments for hard-to-control asthma become more available, pediatricians and primary care clinicians should follow the latest clinical guidelines for referring children to specialists for asthma care, said Dr. Geissler.

“Additionally, asthma specialists should ensure that their practices are accessible to children with Medicaid, as these families may face higher barriers to care; for example, transportation needs or scheduling challenges,” she said. Other strategies to overcome barriers to care might include electronic consultations with specialists or primary care–oriented interdisciplinary asthma clinics, which may be useful for all children with asthma but may particularly benefit those insured by Medicaid, she noted.

“Based on data limitations, we could not examine why we observed such big differences in specialist use by insurance type; for example, whether pediatricians were referring to specialists less for Medicaid-insured kids, or whether kids with Medicaid were less likely to see a specialist after a referral was made,” Dr. Geissler said. More research is needed to examine not only these factors but also the appropriateness of specialty care based on clinical guidelines to ensure high-quality evidence-based care for children with asthma who are insured by Medicaid, she said.
 

Improve Access and Expand Analysis

Asthma is a chronic and prevalent disease and requires a comprehensive approach that sometimes calls for specialist care, Anne Coates, MD, a pediatric pulmonologist in Portland, Maine, said in an interview.

Dr. Coates said she was surprised by the results of the current study but commended the authors for highlighting the limitations of the study, which illustrate areas for additional research. Notably, “the authors couldn’t observe referrals to specialists from primary care physicians; they used completed visits as a proxy,” Dr. Coates said.

More studies are needed to assess the completion of referral visits regardless of children’s insurance in order to better understand and address the barriers to specialty care, she added.

The current study is important because of the extent of asthma coupled with the significant number of children across the United States who are insured by Medicaid, especially underserved populations, she said.

“The burden of asthma differentially affects people of color who are living in lower resourced areas, and it is important in further research to understanding the barriers to helping people get the care they need,” Dr. Coates told this news organization. Some alternatives might include telehealth visits or even a hybrid visit to a primary care provider (PCP) who has high-speed internet, and the specialist could then conduct a telehealth visit from the PCP’s office, with the PCP acting as on-site eyes and ears, said Dr. Coates, who has used this strategy in her practice in Maine, where many patients live far from specialist care.

The study was supported by the National Heart, Lung, and Blood Institute and the University of Massachusetts Center for Clinical and Translational Science-Biostatistics, Epidemiology & Research Design Component. Dr. Geissler and Dr. Coates had no financial conflicts to disclose.

The Food and Drug Administration has approved ustekinumab-ttwe (Pyzchiva) as a biosimilar to ustekinumab (Stelara) for the treatment of multiple inflammatory conditions.

In addition, the agency “provisionally determined” that the medication would be interchangeable with the reference product but that designation would not take hold until the interchangeability exclusivity period for the first approved biosimilar ustekinumab-auub (Wezlana) expires, according to a press release. This designation would, depending on state law, allow a pharmacist to substitute the biosimilar for the reference product without involving the prescribing clinician. It’s unclear when ustekinumab-auub’s interchangeability exclusivity ends.

Ustekinumab-ttwe, a human interleukin (IL)-12 and IL-23 antagonist, is indicated for the treatment of:

• Moderate to severe plaque psoriasis in adults and pediatric patients aged 6 years or older who are candidates for phototherapy or systemic therapy 
• Active psoriatic arthritis in adults and pediatric patients aged 6 years or older with moderately to severely active Crohn’s disease or ulcerative colitis

It is administered via subcutaneous injection in 45 mg/0.5 mL and 90 mg/mL prefilled syringes or via intravenous infusion in 130 mg/26 mL (5 mg/mL) single-dose vial. 

Developed by Samsung Bioepis, ustekinumab-ttwe will be commercialized by Sandoz in the United States. Besides ustekinumab-auub, the other ustekinumab biosimilar is ustekinumab-aekn (Selarsdi).

Ustekinumab-ttwe is expected to launch in February 2025 “in accordance with the settlement and license agreement with Janssen Biotech,” which manufacturers the reference product, Sandoz said. The other approved ustekinumab biosimilars will launch within a similar time frame.

In addition, the agency “provisionally determined” that the medication would be interchangeable with the reference product but that designation would not take hold until the interchangeability exclusivity period for the first approved biosimilar ustekinumab-auub (Wezlana) expires, according to a press release. This designation would, depending on state law, allow a pharmacist to substitute the biosimilar for the reference product without involving the prescribing clinician. It’s unclear when ustekinumab-auub’s interchangeability exclusivity ends.

Ustekinumab-ttwe, a human interleukin (IL)-12 and IL-23 antagonist, is indicated for the treatment of:

• Moderate to severe plaque psoriasis in adults and pediatric patients aged 6 years or older who are candidates for phototherapy or systemic therapy 
• Active psoriatic arthritis in adults and pediatric patients aged 6 years or older with moderately to severely active Crohn’s disease or ulcerative colitis

It is administered via subcutaneous injection in 45 mg/0.5 mL and 90 mg/mL prefilled syringes or via intravenous infusion in 130 mg/26 mL (5 mg/mL) single-dose vial. 

Developed by Samsung Bioepis, ustekinumab-ttwe will be commercialized by Sandoz in the United States. Besides ustekinumab-auub, the other ustekinumab biosimilar is ustekinumab-aekn (Selarsdi).

Ustekinumab-ttwe is expected to launch in February 2025 “in accordance with the settlement and license agreement with Janssen Biotech,” which manufacturers the reference product, Sandoz said. The other approved ustekinumab biosimilars will launch within a similar time frame.

Individuals with anxiety have at least a twofold higher risk of developing Parkinson’s disease than those without anxiety, new research suggested.

Investigators drew on 10-year data from primary care registry to compare almost 110,000 patients who developed anxiety after the age of 50 years with close to 900,000 matched controls without anxiety.

After adjusting for a variety of sociodemographic, lifestyle, psychiatric, and neurological factors, they found that the risk of developing Parkinson’s disease was double in those with anxiety, compared with controls.

“Anxiety is known to be a feature of the early stages of Parkinson’s disease, but prior to our study, the prospective risk of Parkinson’s in those over the age of 50 with new-onset anxiety was unknown,” colead author Juan Bazo Alvarez, a senior research fellow in the Division of Epidemiology and Health at University College London, London, England, said in a news release.

The study was published online in the British Journal of General Practice.

The presence of anxiety is increased in prodromal Parkinson’s disease, but the prospective risk for Parkinson’s disease in those aged 50 years or older with new-onset anxiety was largely unknown.

Investigators analyzed data from a large UK primary care dataset that includes all people aged between 50 and 99 years who were registered with a participating practice from Jan. 1, 2008, to Dec. 31, 2018.

They identified 109,435 people (35% men) with more than one anxiety record in the database but no previous record of anxiety for 1 year or more and 878,256 people (37% men) with no history of anxiety (control group).

Features of Parkinson’s disease such as sleep problems, depression, tremor, and impaired balance were then tracked from the point of the anxiety diagnosis until 1 year before the Parkinson’s disease diagnosis.

Among those with anxiety, 331 developed Parkinson’s disease during the follow-up period, with a median time to diagnosis of 4.9 years after the first recorded episode of anxiety.

The incidence of Parkinson’s disease was 1.2 per 1000 person-years (95% CI, 0.92-1.13) in those with anxiety versus 0.49 (95% CI, 0.47-0.52) in those without anxiety.

After adjustment for age, sex, social deprivation, lifestyle factors, severe mental illness, head trauma, and dementia, the risk for Parkinson’s disease was double in those with anxiety, compared with the non-anxiety group (hazard ratio, 2.1; 95% CI, 1.9-2.4).

Individuals without anxiety also developed Parkinson’s disease later than those with anxiety.

The researchers identified specific symptoms that were associated with later development of Parkinson’s disease in those with anxiety, including depression, sleep disturbance, fatigue, and cognitive impairment, among other symptoms.

“The results suggest that there is a strong association between anxiety and diagnosis of Parkinson’s disease in patients aged over 50 years who present with a new diagnosis of anxiety,” the authors wrote. “This provides evidence for anxiety as a prodromal presentation of Parkinson’s disease.”

Future research “should explore anxiety in relation to other prodromal symptoms and how this symptom complex is associated with the incidence of Parkinson’s disease,” the researchers wrote. Doing so “may lead to earlier diagnosis and better management of Parkinson’s disease.”

This study was funded by the European Union. Specific authors received funding from the National Institute for Health and Care Research and the Alzheimer’s Society Clinical Training Fellowship program. The authors declared no relevant financial relationships.

New research supports current guidelines cautioning against long-term use of benzodiazepines.

The study of more than 5000 older adults found that benzodiazepine use was associated with an accelerated reduction in the volume of the hippocampus and amygdala — brain regions involved in memory and mood regulation. However, benzodiazepine use overall was not associated with an increased risk for dementia.

The findings suggest that benzodiazepine use “may have subtle, long-term impact on brain health,” lead investigator Frank Wolters, MD, PhD, with Erasmus University Medical Center, Rotterdam, the Netherlands, and colleagues wrote.

The study was published online in BMC Medicine.
 

Conflicting Evidence 

Benzodiazepines are commonly prescribed in older adults for anxiety and sleep disorders. Though the short-term cognitive side effects are well documented, the long-term impact on neurodegeneration and dementia risk remains unclear. Some studies have linked benzodiazepine use to an increased risk for dementia, whereas others have not.

Dr. Wolters and colleagues assessed the effect of benzodiazepine use on long-term dementia risk and on imaging markers of neurodegeneration in 5443 cognitively healthy adults (mean age, 71 years; 57% women) from the population-based Rotterdam Study. 

Benzodiazepine use between 1991 and 2008 was determined using pharmacy dispensing records, and dementia incidence was determined from medical records. 

Half of the participants had used benzodiazepines at any time in the 15 years before baseline (2005-2008); 47% used anxiolytics, 20% used sedative-hypnotics, 34% used both, and 13% were still using the drugs at the baseline assessment. 

During an average follow-up of 11 years, 13% of participants developed dementia. 

Overall, use of benzodiazepines was not associated with dementia risk, compared with never-use (hazard ratio [HR], 1.06), irrespective of cumulative dose. 

The risk for dementia was somewhat higher with any use of anxiolytics than with sedative-hypnotics (HR, 1.17 vs HR, 0.92), although neither was statistically significant. The highest risk estimates were observed for high cumulative dose of anxiolytics (HR, 1.33). 

Sensitivity analyses of the two most commonly used anxiolytics found no differences in risk between use of short half-life oxazepam and long half-life diazepam (HR, 1.01 and HR, 1.06, respectively, for ever-use, compared with never-use for oxazepam and diazepam).
 

Brain Atrophy

The researchers investigated potential associations between benzodiazepine use and brain volumes using brain MRI imaging from 4836 participants.

They found that current use of a benzodiazepine at baseline was significantly associated with lower total brain volume — as well as lower hippocampus, amygdala, and thalamus volume cross-sectionally — and with accelerated volume loss of the hippocampus and, to a lesser extent, amygdala longitudinally. 

Imaging findings did not differ by type of benzodiazepine used or cumulative dose. 

“Given the availability of effective alternative pharmacological and nonpharmacological treatments for anxiety and sleep problems, it is important to carefully consider the necessity of prolonged benzodiazepine use in light of potential detrimental effects on brain health,” the authors wrote. 
 

Risks Go Beyond the Brain

Commenting on the study, Shaheen Lakhan, MD, PhD, a neurologist and researcher based in Miami, Florida, noted that “chronic benzodiazepine use may reduce neuroplasticity, potentially interfering with the brain’s ability to form new connections and adapt.

“Long-term use can lead to down-regulation of GABA receptors, altering the brain’s natural inhibitory mechanisms and potentially contributing to tolerance and withdrawal symptoms. Prolonged use can also disrupt the balance of various neurotransmitter systems beyond just GABA, potentially affecting mood, cognition, and overall brain function,” said Dr. Lakhan, who was not involved in the study. 

“While the literature is mixed on chronic benzodiazepine use and dementia risk, prolonged use has consistently been associated with accelerated volume loss in certain brain regions, particularly the hippocampus and amygdala,” which are responsible for memory, learning, and emotional regulation, he noted. 

“Beyond cognitive impairments and brain volume loss, chronic benzodiazepine use is associated with tolerance and dependence, potential for abuse, interactions with other drugs, and increased fall risk, especially in older adults,” Dr. Lakhan added.

Current guidelines discourage long-term use of benzodiazepines because of risk for psychological and physical dependence; falls; and cognitive impairment, especially in older adults. Nevertheless, research shows that 30%-40% of older benzodiazepine users stay on the medication beyond the recommended period of several weeks.

Donovan T. Maust, MD, Department of Psychiatry, University of Michigan Medical School, Ann Arbor, said in an interview these new findings are consistent with other recently published observational research that suggest benzodiazepine use is not linked to dementia risk. 

“I realize that such meta-analyses that find a positive relationship between benzodiazepines and dementia are out there, but they include older, less rigorous studies,” said Dr. Maust, who was not part of the new study. “In my opinion, the jury is not still out on this topic. However, there are plenty of other reasons to avoid them — and in particular, starting them — in older adults, most notably the increased risk of fall injury as well as increased overdose risk when taken along with opioids.”

There’s a growing scandal in mental health care. Recent studies are showing that certain medications that basically are used to, if you will, quiet patients — antipsychotic drugs — are being overused, particularly in facilities that serve poorer people and people who are minorities. This situation is utterly, ethically unacceptable and it’s something that we are starting to get really pressed to solve. 

Part of this is due to the fact that numbers of caregivers are in short supply. We need to get more people trained. We need to get more mental health providers at all levels into facilities in order to provide care, and not substitute that inability to have a provider present and minimize risk to patients by having drug-induced sleepiness, soporific behavior, or, if you will, snowing them just because we don’t have enough people to keep an eye on them. Furthermore, we can’t let them engage in some activities, even things like walking around, because we’re worried about falls. The nursing homes or mental health facilities don’t want anybody to get injured, much less killed, because that’s going to really bring government agencies down on them.

What do we do, aside from trying to get more numbers in there? California came up with a law not too long ago that basically put the burden of using these drugs on consent. They passed a law that said the patient, before going under and being administered any type of psychoactive drug, has to consent; or if they’re really unable to do that, their relative or next of kin should have to consent.

California law now puts the burden on getting consent from the patient in order to use these drugs. It’s not a good solution. It still permits the use of the drugs to substitute for the inability to provide adequate numbers of people to provide care in safe environments. It’s almost like saying, “We know you’re going into a dangerous place. We can’t really reduce the danger, so we’re going to make sure that you stay in your seat. You better consent to that because otherwise things could not go well for you in this mental institution.” 

That’s not a sound argument for the use of informed consent. Moreover, I’m very skeptical that many of these people in mental institutions do have the capacity to either say, “Fine, give me psychoactive drugs if I have to stay here,” or “No, I don’t want that. I’ll take my chances.”

They’re vulnerable people. Many of them may not be fully incompetent, but they often have compromised competency. Relatives may be thinking, Well, the right thing to do is just to make sure they don’t get hurt or injure themselves. Yes, give them the drugs. 

Consent, while I support it, is not the solution to what is fundamentally an infrastructure problem, a personnel problem, and one of the shames of American healthcare, which is lousy long-term mental health care. For too many people, their care is in the street. For too many people, their care is taking place in institutions that have dangerous designs where people either get injured, can’t provide enough spacing, or just don’t have the people to do it. 

Let’s move to fix the mental health care system and not be in a situation where we say to people, “The system stinks and you’re at risk. Is it okay with you if we drug you because we can’t think of any other way to keep you safe, given the rotten nature of the institutions that we’ve got?”

They’re vulnerable people. Many of them may not be fully incompetent, but they often have compromised competency. Relatives may be thinking, Well, the right thing to do is just to make sure they don’t get hurt or injure themselves. Yes, give them the drugs. 

Consent, while I support it, is not the solution to what is fundamentally an infrastructure problem, a personnel problem, and one of the shames of American healthcare, which is lousy long-term mental health care. For too many people, their care is in the street. For too many people, their care is taking place in institutions that have dangerous designs where people either get injured, can’t provide enough spacing, or just don’t have the people to do it. 

Let’s move to fix the mental health care system and not be in a situation where we say to people, “The system stinks and you’re at risk. Is it okay with you if we drug you because we can’t think of any other way to keep you safe, given the rotten nature of the institutions that we’ve got?”

There’s a growing scandal in mental health care. Recent studies are showing that certain medications that basically are used to, if you will, quiet patients — antipsychotic drugs — are being overused, particularly in facilities that serve poorer people and people who are minorities. This situation is utterly, ethically unacceptable and it’s something that we are starting to get really pressed to solve. 

Part of this is due to the fact that numbers of caregivers are in short supply. We need to get more people trained. We need to get more mental health providers at all levels into facilities in order to provide care, and not substitute that inability to have a provider present and minimize risk to patients by having drug-induced sleepiness, soporific behavior, or, if you will, snowing them just because we don’t have enough people to keep an eye on them. Furthermore, we can’t let them engage in some activities, even things like walking around, because we’re worried about falls. The nursing homes or mental health facilities don’t want anybody to get injured, much less killed, because that’s going to really bring government agencies down on them.

What do we do, aside from trying to get more numbers in there? California came up with a law not too long ago that basically put the burden of using these drugs on consent. They passed a law that said the patient, before going under and being administered any type of psychoactive drug, has to consent; or if they’re really unable to do that, their relative or next of kin should have to consent.

California law now puts the burden on getting consent from the patient in order to use these drugs. It’s not a good solution. It still permits the use of the drugs to substitute for the inability to provide adequate numbers of people to provide care in safe environments. It’s almost like saying, “We know you’re going into a dangerous place. We can’t really reduce the danger, so we’re going to make sure that you stay in your seat. You better consent to that because otherwise things could not go well for you in this mental institution.” 

That’s not a sound argument for the use of informed consent. Moreover, I’m very skeptical that many of these people in mental institutions do have the capacity to either say, “Fine, give me psychoactive drugs if I have to stay here,” or “No, I don’t want that. I’ll take my chances.”

They’re vulnerable people. Many of them may not be fully incompetent, but they often have compromised competency. Relatives may be thinking, Well, the right thing to do is just to make sure they don’t get hurt or injure themselves. Yes, give them the drugs.

Analysis of finger sweat detected isoniazid in adults with tuberculosis (TB) for ≤ 6 hours after administration, based on data from a new pilot study.

Risk factors for TB treatment failure include poor medication compliance and insufficient exposure to medications, but measurement of drugs in samples of blood, saliva, or sweat can help assess adherence and inform dose adjustments, Katherine Longman, a PhD student at the University of Surrey, Guildford, England, and colleagues wrote.

Although TB is treatable, “it is well known that insufficient drug dosing leads to treatment failure and drug resistance, and so ensuring that patients have sufficient drug exposure is important,” said corresponding author Melanie J. Bailey, PhD, also of the University of Surrey.

“This can be carried out using blood, but blood is painful to collect and difficult to transport. Finger sweat offers a completely noninvasive way to sample patients,” but its use to determine medication adherence has not been examined, she said.

In a pilot study published in the International Journal of Antimicrobial Agents, the researchers reviewed data from 10 adults with TB who provided finger sweat, blood, and saliva samples at several time points ≤ 6 hours after receiving a controlled dose of isoniazid (median of 300 mg daily). They used liquid chromatography–mass spectrometry to examine the samples.

Overall, “isoniazid and acetyl isoniazid were detected in at least one finger sweat sample from all patients,” with detection rates of 96% and 77%, respectively, the researchers wrote. Given the short half-life of isoniazid, they used a window of 1-6 hours after administration. Isoniazid was consistently detected between 1 and 6 hours after administration, while acetyl isoniazid had a noticeably higher detection rate at 6 hours.

The researchers also examined creatinine to account for variability in volume of sweat samples, and found that finger sweat was significantly correlated to isoniazid concentration. The maximum isoniazid to creatinine ratio in finger sweat occurred mainly in the first hour after drug administration, and the activity of isoniazid in finger sweat over time reflected isoniazid concentration in serum more closely after normalization to creatinine, they said. The Pearson’s correlation coefficient (r) was 0.98 (P < .001; one-tailed), with normalization to creatinine, compared with r = 0.52 without normalization (P = .051).

The study findings were limited by several factors including the lack of knowledge of the last drug dose and lack of confirmation testing with an established method of analysis, the researchers noted. However, the results support the potential of the finger sweat test as a screening tool to indicate patients’ nonadherence or to identify patients at risk of low medication exposure.

“We were surprised that we were able to detect the drug in so many patient samples because the sample volume is so low, and so detection is challenging,” said Dr. Bailey. “We were also surprised that fingerprint and drug levels correlated so well after normalizing to creatinine. This is exciting as it unlocks the possibility to test drug levels, as well as providing a yes/no test.”

In practice, the finger sweat technique could reduce the burden on clinics by offering a completely noninvasive way to test a patient’s medication adherence. Looking ahead, more research is needed to explore whether creatinine normalization is widely applicable, such as whether it works for patients with abnormal kidney function, she added.
 

Noninvasive Option May Mitigate Treatment Challenges

The current study presents a strategy that might address current limitations in TB management, said Krishna Thavarajah, MD, a pulmonologist and director of the interstitial lung disease program at Henry Ford Hospital, Detroit, Michigan, in an interview.

Both self-administered treatment and directly observed therapy (DOT) for TB therapy have limitations, including adherence as low as 50% for TB regimens, she said. In addition, “DOT availability and efficacy can be limited by cost, personnel availability from an administration perspective, and by distrust of those being treated.”

In the current study, “I was struck by the correlation between the sweat and serum values of [isoniazid] and by the level of sophistication of noninvasive testing, being able to normalize for creatinine to account for different volumes of sweat,” said Dr. Thavarajah. In clinical practice, finger sweat isoniazid could potentially serve as an adjunct or alternative to DOT in patients with TB.

Although adherence to the sampling protocol and possible patient distrust of the process (such as concerns over what else is being collected in their sweat) might be barriers to the use of a finger sweat strategy in the clinical setting, appropriate patient selection, patient training, and encouraging clinicians to incorporate this testing into practice could overcome these barriers, said Dr. Thavarajah.

However, more research is needed to study the finger sweat strategy in larger, real-world samples and to study accuracy and treatment adherence with monitoring in a population undergoing DOT, she said.

The study was supported by the Engineering & Physical Sciences Research Council and by Santander PhD Mobility Awards 2019. The researchers had no financial conflicts to disclose. Dr. Thavarajah had no financial conflicts to disclose.

The Diagnosis: Congenital Hemangioma

Surgical resection of the mass was performed at 4 months of age without complication (Figure 1). Histopathology revealed a lobular endothelial cell proliferation within a densely fibrotic stroma, multiple thin-walled vessels, and negative immunoreactivity to glucose transporter type 1 (GLUT-1)(Figures 2 and 3). Combined with the patient’s clinical history and findings on imaging (Figure 4), the most accurate diagnosis was a congenital hemangioma (CH). The mass was determined to be a noninvoluting congenital hemangioma (NICH).

A variety of vascular anomalies manifest in newborns and can be differentiated by the patient’s clinical history—particularly whether the lesion is present at birth or develops after birth. Imaging and histopathology of the lesion(s) may be utilized when clinical examination alone is not sufficient to make a diagnosis. Histopathology and immunohistochemistry further aid in differentiating the type of vascular lesion.

Overall, vascular anomalies are classified broadly into 2 categories based on their pathogenesis: tumors and malformations. Vascular tumors are composed of proliferating endothelial cells that have the potential to resolve spontaneously over time. Examples include CH, infantile hemangioma (IH), kaposiform hemangioendothelioma (KHE), and tufted angioma (TA). In contrast, vascular malformations (ie, arteriovenous malformations) are composed of dysplastic vessels with normal endothelial cell turnover and do not resolve without intervention.¹

Congenital hemangiomas are rare vascular tumors that are fully developed at birth. These tumors proliferate in utero, enabling prenatal detection via ultrasonography as early as 12 weeks’ gestation for large heterogeneous vascular masses.^2-4 Congenital hemangiomas are described as solitary, well-circumscribed, raised, violaceous lesions most commonly located in the head and neck region.^4-6 Histopathologically, they are characterized by lobules of proliferating capillaries surrounded by fibrous stroma and dysplastic vascular channels.^6,7

Congenital hemangiomas are categorized based on their postnatal involution patterns.2 Fetally involuting CH both develops and begins regression in utero and often is completely regressed at birth.⁸ Rapidly involuting CH begins regression in the first few weeks of life and usually is completely involuted by 14 months of age.6,9-11 Conversely, NICH does not regress, often requiring surgical excision due to functional and cosmetic issues.^12,13 Partially involuting CH is intermediary, beginning as rapidly involuting but not involuting completely and persisting as lesions that resemble NICH.^14-16 Although generally benign and asymptomatic, these tumors can cause transient thrombocytopenia and coagulopathy at birth, as seen in our patient.^17,18

Infantile hemangioma is the most common vascular tumor of infancy.^19-21 Although a precursor lesion may be present at birth, generally this tumor becomes apparent after the first few weeks of life as a solitary vascular plaque or nodule with a predilection for the head and neck.^22-25 Once it arises, IH quickly enters a period of rapid growth, followed by a period of slower continued growth, with most reaching maximum size by 3 months.²² Thereafter, IH enters a slow period of involution (range, 3–9 years)²⁶; more recent data suggest near resolution by 5 years of age.²⁷ Infantile hemangioma is categorized based on its depth in the skin and subcutaneous tissues and can be classified as superficial, mixed, or deep.^22,24,28,29 Superficial IH appears as a red plaque and may exhibit lobulation, while deep IH can be identified as flesh-colored or blue subcutaneous masses. Mixed IH may manifest with both superficial and deep features depending on the extent of its involvement in the dermal and subcutaneous layers. The pattern of involvement may be focal, segmental, or indeterminate.²⁴ In contrast, CH typically is a solitary vascular mass with prominent telangiectases, nodules, and radiating veins.⁶ Histologically, IH is composed of proliferative plump endothelial cells that form capillaries, and the lesion stains positively for GLUT-1, whereas CH does not.³⁰

Kaposiform hemangioendothelioma is classified as a locally aggressive vascular tumor that manifests either prenatally or in early infancy.³¹ It is described as a solitary, ill-defined, firm, purple plaque most commonly located on the extremities and retroperitoneum.^32-34 Histopathologically, these lesions are characterized by dilated lymphatic channels and irregular sheets or lobules of spindle-shaped endothelial cells infiltrating the dermis and subcutaneous fat.^33,35 In contrast to CH, KHE lesions show immunoreactivity to the markers podoplanin, lymphatic vessel endothelial receptor 1, and prospero homeobox 1 protein.^36,37 Notably, 70% of these tumors are complicated by the presence of Kasabach-Merritt phenomenon, a potentially life-threatening emergency that occurs when platelets are trapped within a vascular tumor, leading to the consumption of clotting factors, intralesional bleeding, and rapid enlargement of the tumor.³² The Kasabach-Merritt phenomenon manifests clinically as microangiopathic hemolytic anemia, severe thrombocytopenia, and disseminated intravascular coagulation. ³⁸ Although CH lesions also can be associated with thrombocytopenia and coagulopathy, they generally are mild and self-limited.¹⁸

Tufted angioma is a vascular tumor that arises within the first 5 years of life as firm violaceous papules or plaques, often with associated hyperhidrosis or hypertrichosis.^39,40 Although TA grows slowly for a period of time, it eventually stabilizes and persists, rarely regressing completely.⁴¹ These tumors share many similarities with KHE, and it has been suggested that they may be part of the same spectrum. 42 As with KHE, TA lesions show immunoreactivity to the markers podoplanin, lymphatic vessel endothelial receptor 1, and prospero homeobox 1 protein, which are negative in CH.^36,37 Although TA also can be complicated by Kasabach-Merritt phenomenon, the incidence is much lower (up to 38%).^43,44 As such, TAs tend to be recognized as more superficial benign lesions. However, they still can cause notable cosmetic and functional impairment and should be monitored closely, especially in the presence of associated symptoms or complications.

Arteriovenous malformation is a vascular lesion that results from errors during the embryonic development of vascular channels.⁴⁵ Although present at birth, it may not become clinically apparent until later in life. Arteriovenous malformations enlarge postnatally, and their growth is proportional to the developmental growth of the affected individual rather than the result of endothelial proliferation.⁴⁶ In infants, AVM may manifest as a faint vascular stain that can evolve over time into a pink patch associated with a palpable thrill during adolescence. ⁴ On Doppler flow imaging, AVMs are identified as fast-flow anomalies arising from an abnormal communication between high-pressure arterial systems and low-pressure venous systems without the presence of a capillary bed.⁴⁷ One of the differentiating factors between AVM and CH is that AVMs do not regress spontaneously and tend to have high recurrence rates, even with intervention. ⁴⁸ In contrast, CH can be categorized based on its postnatal involution pattern. Another distinguishing factor is that AVMs tend to be larger and more invasive than CHs.⁴⁶ Therefore, early diagnosis and intervention are crucial to prevent complications such as bleeding, seizures, or neurologic deficits associated with AVMs.¹

In contrast, vascular malformations (ie, arteriovenous malformations) are composed of dysplastic vessels with normal endothelial cell turnover and do not resolve without intervention.¹

Congenital hemangiomas are rare vascular tumors that are fully developed at birth. These tumors proliferate in utero, enabling prenatal detection via ultrasonography as early as 12 weeks’ gestation for large heterogeneous vascular masses.^2-4 Congenital hemangiomas are described as solitary, well-circumscribed, raised, violaceous lesions most commonly located in the head and neck region.^4-6 Histopathologically, they are characterized by lobules of proliferating capillaries surrounded by fibrous stroma and dysplastic vascular channels.^6,7

Congenital hemangiomas are categorized based on their postnatal involution patterns.2 Fetally involuting CH both develops and begins regression in utero and often is completely regressed at birth.⁸ Rapidly involuting CH begins regression in the first few weeks of life and usually is completely involuted by 14 months of age.6,9-11 Conversely, NICH does not regress, often requiring surgical excision due to functional and cosmetic issues.^12,13 Partially involuting CH is intermediary, beginning as rapidly involuting but not involuting completely and persisting as lesions that resemble NICH.^14-16 Although generally benign and asymptomatic, these tumors can cause transient thrombocytopenia and coagulopathy at birth, as seen in our patient.^17,18

Infantile hemangioma is the most common vascular tumor of infancy.^19-21 Although a precursor lesion may be present at birth, generally this tumor becomes apparent after the first few weeks of life as a solitary vascular plaque or nodule with a predilection for the head and neck.^22-25 Once it arises, IH quickly enters a period of rapid growth, followed by a period of slower continued growth, with most reaching maximum size by 3 months.²² Thereafter, IH enters a slow period of involution (range, 3–9 years)²⁶; more recent data suggest near resolution by 5 years of age.²⁷ Infantile hemangioma is categorized based on its depth in the skin and subcutaneous tissues and can be classified as superficial, mixed, or deep.^22,24,28,29 Superficial IH appears as a red plaque and may exhibit lobulation, while deep IH can be identified as flesh-colored or blue subcutaneous masses. Mixed IH may manifest with both superficial and deep features depending on the extent of its involvement in the dermal and subcutaneous layers. The pattern of involvement may be focal, segmental, or indeterminate.²⁴ In contrast, CH typically is a solitary vascular mass with prominent telangiectases, nodules, and radiating veins.⁶ Histologically, IH is composed of proliferative plump endothelial cells that form capillaries, and the lesion stains positively for GLUT-1, whereas CH does not.³⁰

Kaposiform hemangioendothelioma is classified as a locally aggressive vascular tumor that manifests either prenatally or in early infancy.³¹ It is described as a solitary, ill-defined, firm, purple plaque most commonly located on the extremities and retroperitoneum.^32-34 Histopathologically, these lesions are characterized by dilated lymphatic channels and irregular sheets or lobules of spindle-shaped endothelial cells infiltrating the dermis and subcutaneous fat.^33,35 In contrast to CH, KHE lesions show immunoreactivity to the markers podoplanin, lymphatic vessel endothelial receptor 1, and prospero homeobox 1 protein.^36,37 Notably, 70% of these tumors are complicated by the presence of Kasabach-Merritt phenomenon, a potentially life-threatening emergency that occurs when platelets are trapped within a vascular tumor, leading to the consumption of clotting factors, intralesional bleeding, and rapid enlargement of the tumor.³² The Kasabach-Merritt phenomenon manifests clinically as microangiopathic hemolytic anemia, severe thrombocytopenia, and disseminated intravascular coagulation. ³⁸ Although CH lesions also can be associated with thrombocytopenia and coagulopathy, they generally are mild and self-limited.¹⁸

Tufted angioma is a vascular tumor that arises within the first 5 years of life as firm violaceous papules or plaques, often with associated hyperhidrosis or hypertrichosis.^39,40 Although TA grows slowly for a period of time, it eventually stabilizes and persists, rarely regressing completely.⁴¹ These tumors share many similarities with KHE, and it has been suggested that they may be part of the same spectrum. 42 As with KHE, TA lesions show immunoreactivity to the markers podoplanin, lymphatic vessel endothelial receptor 1, and prospero homeobox 1 protein, which are negative in CH.^36,37 Although TA also can be complicated by Kasabach-Merritt phenomenon, the incidence is much lower (up to 38%).^43,44 As such, TAs tend to be recognized as more superficial benign lesions. However, they still can cause notable cosmetic and functional impairment and should be monitored closely, especially in the presence of associated symptoms or complications.

Arteriovenous malformation is a vascular lesion that results from errors during the embryonic development of vascular channels.⁴⁵ Although present at birth, it may not become clinically apparent until later in life. Arteriovenous malformations enlarge postnatally, and their growth is proportional to the developmental growth of the affected individual rather than the result of endothelial proliferation.⁴⁶ In infants, AVM may manifest as a faint vascular stain that can evolve over time into a pink patch associated with a palpable thrill during adolescence. ⁴ On Doppler flow imaging, AVMs are identified as fast-flow anomalies arising from an abnormal communication between high-pressure arterial systems and low-pressure venous systems without the presence of a capillary bed.⁴⁷ One of the differentiating factors between AVM and CH is that AVMs do not regress spontaneously and tend to have high recurrence rates, even with intervention. ⁴⁸ In contrast, CH can be categorized based on its postnatal involution pattern. Another distinguishing factor is that AVMs tend to be larger and more invasive than CHs.⁴⁶ Therefore, early diagnosis and intervention are crucial to prevent complications such as bleeding, seizures, or neurologic deficits associated with AVMs.¹

I am not planning on having a headstone on my grave, or even having a grave for that matter. However, if my heirs decide to ignore my wishes and opt for some pithy observation chiseled into a tastefully sized granite block, I suspect they might choose “He always knew which way the wind was blowing ... but wasn’t so sure about the tides.” Which aptly describes both my navigational deficiencies they have observed here over my six decades on the Maine coast as well as my general inability to predict the future. Nonetheless, I am going to throw caution to the wind and take this opportunity to ponder where obesity in this country will go over the next couple of decades.

In March of last year the London-based World Obesity Federation published its World Obesity Atlas. In the summary the authors predict that based on current trends “obesity will cost the global economy of US $4 trillion of potential income in 2035, nearly 3% of current global domestic product (GDP).” They envision the “rising prevalence of obesity to be steepest among children and adolescents rising from 10% to 20% of the world’s boys during the period 2029 to 2035, and rising fro 8% to 18% of the world’s girls.”

These dire predictions assume no significant measures to reverse this trajectory such as universal health coverage. Nor do the authors attempt to predict the effect of the growing use of GLP-1 agonists. This omission is surprising and somewhat refreshing given the fact that the project was funded by an unrestricted grant from Novo Nordisk, a major producer of one of these drugs.

Unfortunately, I think it is unlikely that over the next couple of decades any large countries who do not already have a functioning universal health care system will find the political will to develop one capable of reversing the trend toward obesity. Certainly, I don’t see it in the cards for this country.

On the other hand, I can foresee the availability and ease of administration for GLP-1 agonists and similar drugs improving over the near term. However, the cost and availability will continue to widen the separation between the haves and the have-nots, both globally and within each country. This will mean that the countries and population subgroups that already experience the bulk of the economic and health consequences of obesity will continue to shoulder an outsized burden of this “disease.”

It is unclear how much this widening of the fat-getting-fatter dynamic will add to the global and national political unrest that already seems to be tracking the effects of climate change. However, I can’t imaging it is going to be a calming or uniting force.

Narrowing our focus from an international to an individual resource-rich country such as the United States, let’s consider what the significant growth in availability and affordability of GLP-1 agonist drugs will mean. There will certainly be short-term improvements in the morbidity and mortality of some of the obesity related diseases. However, for other conditions it may take longer than two decades for us to notice an effect. While it is tempting to consider these declines as a financial boon for the country that already spends a high percentage of its GDP on healthcare. However, as the well-known Saturday Night Live pundit Roseanne Roseannadanna often observed, ”it’s always something ... if it’s not one thing it’s another.” There may be other non-obesity conditions that surge to fill the gap, leaving us still with a substantial financial burden for healthcare.

Patients taking GLP-1 agonists lose weight because they feel full and eat less food. While currently the number of patients taking these drugs is relatively small, the effect on this country’s food consumption is too small to calculate. However, let’s assume that 20 years from now half of the obese patients are taking appetite blunting medication. Using today’s statistics this means that 50 million adults will be eating significantly less food. Will the agriculturists have gradually adjusted to produce less food? Will this mean there is more food for the those experiencing “food insecurity”? I doubt it. Most food insecurity seems to be a problem of distribution and inequality, not supply.

Physicians now caution patients taking GLP-1 agonists to eat a healthy and balanced diet. When the drugs are more commonly available, will this caution be heeded by the majority? Will we see a population that may no longer be obese but nonetheless malnourished because of bad choices?

And, finally, in a similar vein, will previously obese individuals suddenly or gradually begin to be more physically active once the appetite blunting medicines have helped them lose weight? Here, I have my doubts. Of course, some leaner individuals begin to take advantage of their new body morphology. But, I fear that old sedentary habits will die very slowly for most, and not at all for many. We have built a vehicle-centric society in which being physically active requires making a conscious effort. Electronic devices and sedentary entertainment options are not going to disappear just because a significant percentage of the population is no longer obese.

So there you have it. I suspect that I am correct about which way some of the winds are blowing as the obesity becomes moves into its treatable “disease” phase. But, as always, I haven’t a clue which way the tide is running.

TOPLINE:

More than two thirds of children with conjunctivitis received antibiotics within a day of their initial ambulatory care visit; however, follow-up visits and new antibiotic dispensations were rare regardless of treatment, suggesting that not receiving antibiotics may not lead to additional health care use.

METHODOLOGY:

• Researchers evaluated the frequency of topical antibiotic treatment and its association with subsequent health care use among commercially insured children with acute infectious conjunctivitis in the United States.
• This cohort study analyzed data from the 2021 MarketScan Commercial Claims and Encounters Database, including 44,793 children with conjunctivitis (median age, 5 years; 47% girls) and ambulatory care encounters.
• The primary exposure was a topical antibiotic prescription dispensed within 1 day of an ambulatory care visit, with outcomes assessed 2-14 days after the visit.
• The primary outcomes were ambulatory care revisits for conjunctivitis and same-day dispensation of a new topical antibiotic, and secondary outcomes included emergency department revisits and hospitalizations.

TAKEAWAY:

• Topical antibiotics were dispensed within a day of an ambulatory care visit in 69% of the cases; however, they were less frequently dispensed following visits to eye clinics (34%), for children aged 6-11 years (66%), and for those with viral conjunctivitis (28%).
• Ambulatory care revisits for conjunctivitis within 2 weeks occurred in only 3.2% of children who had received antibiotics (adjusted odds ratio [aOR], 1.11; 95% CI, 0.99-1.25).
• Similarly, revisits with same-day dispensation of a new antibiotic were also rare (1.4%), with no significant association between antibiotic treatment and revisits (aOR, 1.10; 95% CI, 0.92-1.33).
• Hospitalizations for conjunctivitis occurred in 0.03% of cases, and emergency department revisits occurred in 0.12%, with no differences between children who received antibiotics and those who did not.

IN PRACTICE:

“Given that antibiotics may not be associated with improved outcomes or change in subsequent health care use and are associated with adverse effects and antibiotic resistance, efforts to reduce overtreatment of acute infectious conjunctivitis are warranted,” the authors wrote.

SOURCE:

The study was led by Daniel J. Shapiro, MD, MPH, of the Department of Emergency Medicine at the University of California, San Francisco, and published online on June 27, 2024, in JAMA Ophthalmology.

LIMITATIONS:

The major limitations of the study included the inability to distinguish scheduled visits from unscheduled revisits, incomplete clinical data such as rare complications of conjunctivitis, and the inability to confirm the accuracy of the coded diagnosis of infectious conjunctivitis, especially in children who did not receive a thorough eye examination.

DISCLOSURES:

This study did not declare receiving funding from any sources. One author reported receiving grants from several sources outside the submitted work.
