Once again, America is deeply divided before a national election, with people on each side convinced of the horrors that will be visited upon us if the other side wins. 

’Tis the season — and regrettably, not to be jolly but to be worried.

As a neuroscientist, I am especially aware of the deleterious mental and physical impact of chronic worry on our citizenry. That’s because worry is not “all in your head.” Chronic mild stress drives a panoply of negative changes in your body and brain that add to your risk for physical and neurologic troubles. We modern humans live in a world of worry which appears to be progressively growing.
 

Flight or Fight

Worry stems from the brain’s rather remarkable ability to foresee and reflexively respond to threat. Our “fight or flight” brain machinery probably arose in our vertebrate ancestors more than 300 million years ago. The fact that we have machinery akin to that possessed by lizards or tigers or shrews is testimony to its crucial contribution to our species’ survival.

As the phrase “fight or flight” suggests, a brain that senses trouble immediately biases certain body and brain functions. As it shifts into a higher-alert mode, it increases the energy supplies in our blood and supports other changes that facilitate faster and stronger reactions, while it shuts down less essential processes which do not contribute to hiding, fighting, or running like hell.

This hyperreactive response is initiated in the amygdala in the anterior brain, which identifies “what’s happening” as immediately or potentially threatening. The now-activated amygdala generates a response in the hypothalamus that provokes an immediate increase of adrenaline and cortisol in the body, and cortisol and noradrenaline in the brain. Both sharply speed up our physical and neurologic reactivity. In the brain, that is achieved by increasing the level of excitability of neurons across the forebrain. Depending on the perceived level of threat, an excitable brain will be just a little or a lot more “on alert,” just a little or a lot faster to respond, and just a little or a lot better at remembering the specific “warning” events that trigger this lizard-brain response. 

Alas, this machinery was designed to be engaged every so often when a potentially dangerous surprise arises in life. When the worry and stress are persistent, the brain experiences a kind of neurologic “burn-out” of its fight versus flight machinery.
 

Dangers of Nonstop Anxiety and Stress

A consistently stressed-out brain turns down its production and release of noradrenaline, and the brain becomes less attentive, less engaged. This sets the brain on the path to an anxiety (and then a depressive) disorder, and, in the longer term, to cognitive losses in memory and executive control systems, and to emotional distortions that can lead to substance abuse or other addictions.

Our political distress is but one source of persistent worry and stress. Worry is a modern plague. The head counts of individuals seeking psychiatric or psychological health are at an all-time high in the United States. Near-universal low-level stressors, such as 2 years of COVID, insecurities about the changing demands of our professional and private lives, and a deeply divided body politic are unequivocally affecting American brain health.

The brain also collaborates in our body’s response to stress. Its regulation of hormonal responses and its autonomic nervous system’s mediated responses contribute to elevated blood sugar levels, to craving high-sugar foods, to elevated blood pressure, and to weaker immune responses. This all contributes to higher risks for cardiovascular and other dietary- and immune system–related disease. And ultimately, to shorter lifespans.
 

Strategies to Address Neurologic Changes Arising From Chronic Stress

There are many things you can try to bring your worry back to a manageable (and even productive) level.

• Engage in a “reset” strategy several times a day to bring your amygdala and locus coeruleus back under control. It takes a minute (or five) of calm, positive meditation to take your brain to a happy, optimistic place. Or use a mindfulness exercise to quiet down that overactive amygdala.
• Talk to people. Keeping your worries to yourself can compound them. Hashing through your concerns with a family member, friend, professional coach, or therapist can help put them in perspective and may allow you to come up with strategies to identify and neurologically respond to your sources of stress.
• Exercise, both physically and mentally. Do what works for you, whether it’s a run, a long walk, pumping iron, playing racquetball — anything that promotes physical release. Exercise your brain too. Engage in a project or activity that is mentally demanding. Personally, I like to garden and do online brain exercises. There’s nothing quite like yanking out weeds or hitting a new personal best at a cognitive exercise for me to notch a sense of accomplishment to counterbalance the unresolved issues driving my worry.
• Accept the uncertainty. Life is full of uncertainty. To paraphrase from Yale theologian Reinhold Niebuhr’s “Serenity Prayer”: Have the serenity to accept what you cannot help, the courage to change what you can, and the wisdom to recognize one from the other.

And, please, be assured that you’ll make it through this election season.

Practice Gap

Longitudinal melanonychia (LM) is characterized by the presence of a dark brown, longitudinal, pigmented band on the nail unit, often caused by melanocytic activation or melanocytic hyperplasia in the nail matrix. Distinguishing between benign and early malignant LM is crucial due to their similar clinical presentations.¹ Hence, surgical excision of the pigmented nail matrix followed by histopathologic examination is a common procedure aimed at managing LM and reducing the risk for delayed diagnosis of subungual melanoma.

Tangential matrix excision combined with the nail window technique has emerged as a common and favored surgical strategy for managing LM.² This method is highly valued for its ability to minimize the risk for severe permanent nail dystrophy and effectively reduce postsurgical pigmentation recurrence.

The procedure begins with the creation of a matrix window along the lateral edge of the pigmented band followed by 1 lateral incision carefully made on each side of the nail fold. This meticulous approach allows for the complete exposure of the pigmented lesion. Subsequently, the nail fold is separated from the dorsal surface of the nail plate to facilitate access to the pigmented nail matrix. Finally, the target pigmented area is excised using a scalpel.

Despite the recognized efficacy of this procedure, challenges do arise, particularly when the width of the pigmented matrix lesion is narrow. Holding the scalpel horizontally to ensure precise excision can prove to be demanding, leading to difficulty achieving complete lesion removal and obtaining the desired cosmetic outcomes. As such, there is a clear need to explore alternative tools that can effectively address these challenges while ensuring optimal surgical outcomes for patients with LM. We propose the use of the customized dermal curette.

The Technique

An improved curette tool is a practical solution for complete removal of the pigmented nail matrix. This enhanced instrument is crafted from a sterile disposable dermal curette with its top flattened using a needle holder(Figure 1). Termed the customized dermal curette, this device is a simple yet accurate tool for the precise excision of pigmented lesions within the nail matrix. Importantly, it offers versatility by accommodating different widths of pigmented lesions through the availability of various sizes of dermal curettes (Figure 2).

Histopathologically, we have found that the scalpel technique may lead to variable tissue removal, resulting in differences in tissue thickness, fragility, and completeness (Figure 3A). Conversely, the customized dermal curette consistently provides more accurate tissue excision, resulting in uniform tissue thickness and integrity (Figure 3B).

Practice Implications

Compared to the traditional scalpel, this modified tool offers distinct advantages. Specifically, the customized dermal curette provides enhanced maneuverability and control during the procedure, thereby improving the overall efficacy of the excision process. It also offers a more accurate approach to completely remove pigmented bands, which reduces the risk for postoperative recurrence. The simplicity, affordability, and ease of operation associated with customized dermal curettes holds promise as an effective alternative for tissue shaving, especially in cases involving narrow pigmented matrix lesions, thereby addressing a notable practice gap and enhancing patient care.

The Food and Drug Administration has approved denileukin diftitox-cxdl (Lymphir, Citius Pharmaceuticals) for adults with relapsed or refractory stage 1-3 cutaneous T-cell lymphoma after at least one prior systemic therapy.

The immunotherapy is a reformulation of denileukin diftitox (Ontak), initially approved in 1999 for certain patients with persistent or recurrent cutaneous T-cell lymphoma. In 2014, the original formulation was voluntarily withdrawn from the US market. Citius acquired rights to market a reformulated product outside of Asia in 2021. 

This is the first indication for Lymphir, which targets interleukin-2 receptors on malignant T cells.

This approval marks “a significant milestone” for patients with cutaneous T-cell lymphoma, a rare cancer, company CEO Leonard Mazur said in a press release announcing the approval. “The introduction of Lymphir, with its potential to rapidly reduce skin disease and control symptomatic itching without cumulative toxicity, is expected to expand the [cutaneous T-cell lymphoma] treatment landscape and grow the overall market, currently estimated to be $300-$400 million.” 

Approval was based on the single-arm, open-label 302 study in 69 patients who had a median of four prior anticancer therapies. Patients received 9 mcg/kg daily from day 1 to day 5 of 21-day cycles until disease progression or unacceptable toxicity.

The objective response rate was 36.2%, including complete responses in 8.7% of patients. Responses lasted 6 months or longer in 52% of patients. Over 80% of subjects had a decrease in skin tumor burden, and almost a third had clinically significant improvements in pruritus. 

Adverse events occurring in 20% or more of patients include increased transaminases, decreased albumin, decreased hemoglobin, nausea, edema, fatigue, musculoskeletal pain, rash, chills, constipation, pyrexia, and capillary leak syndrome.

Labeling carries a boxed warning of capillary leak syndrome. Other warnings include visual impairment, infusion reactions, hepatotoxicity, and embryo-fetal toxicity. Citius is under a postmarketing requirement to characterize the risk for visual impairment.

The company expects to launch the agent within 5 months.

TOPLINE:

Greater availability of peripheral tri-iodothyronine (T3), indicated by higher concentrations of free T3, T3, and T3/thyroxine (T4) ratio, is associated with increased liver fat content at baseline and a greater liver fat reduction following a dietary intervention known to reduce liver fat.

METHODOLOGY:

• Systemic hypothyroidism and subclinical hypothyroidism are proposed as independent risk factors for steatotic liver disease, but there are conflicting results in euthyroid individuals with normal thyroid function.
• Researchers investigated the association between thyroid function and intrahepatic lipids in 332 euthyroid individuals aged 50-80 years who reported limited alcohol consumption and had at least one condition for unhealthy aging (eg, cardiovascular disease).
• The analysis drew on a sub-cohort from the NutriAct trial, in which participants were randomly assigned to either an intervention group (diet rich in unsaturated fatty acids, plant protein, and fiber) or a control group (following the German Nutrition Society recommendations).
• The relationship between changes in intrahepatic lipid content and thyroid hormone parameters was evaluated in 243 individuals with data available at 12 months.

TAKEAWAY:

• Higher levels of free T3 and T3/T4 ratio were associated with increased liver fat content at baseline (P = .03 and P = .01, respectively).
• After 12 months, both the intervention and control groups showed reductions in liver fat content, along with similar reductions in free T3, total T3, T3/T4 ratio, and free T3/free T4 ratio (all P < .01).
• Thyroid stimulating hormone, T4, and free T4 levels remained stable in either group during the intervention.
• Participants who maintained higher T3 levels during the dietary intervention experienced a greater reduction in liver fat content over 12 months (Rho = −0.133; P = .039).

IN PRACTICE:

“A higher peripheral concentration of active THs [thyroid hormones] might reflect a compensatory mechanism in subjects with mildly increased IHL [intrahepatic lipid] content and early stages of MASLD [metabolic dysfunction–associated steatotic liver disease],” the authors wrote.

SOURCE:

The study was led by Miriam Sommer-Ballarini, Charité–Universitätsmedizin Berlin, Berlin, Germany. It was published online in the European Journal of Endocrinology.

LIMITATIONS:

Participants younger than 50 years of age and with severe hepatic disease, severe substance abuse, or active cancer were excluded, which may limit the generalizability of the findings. Because the study cohort had only mildly elevated median intrahepatic lipid content at baseline, it may not be suited to address the advanced stages of metabolic dysfunction–associated steatotic liver disease. The study’s findings are based on a specific dietary intervention, which may not be applicable to other dietary patterns or populations.

DISCLOSURES:

The Deutsche Forschungsgemeinschaft and German Federal Ministry for Education and Research funded this study. Some authors declared receiving funding, serving as consultants, or being employed by relevant private companies.

• Systemic hypothyroidism and subclinical hypothyroidism are proposed as independent risk factors for steatotic liver disease, but there are conflicting results in euthyroid individuals with normal thyroid function.
• Researchers investigated the association between thyroid function and intrahepatic lipids in 332 euthyroid individuals aged 50-80 years who reported limited alcohol consumption and had at least one condition for unhealthy aging (eg, cardiovascular disease).
• The analysis drew on a sub-cohort from the NutriAct trial, in which participants were randomly assigned to either an intervention group (diet rich in unsaturated fatty acids, plant protein, and fiber) or a control group (following the German Nutrition Society recommendations).
• The relationship between changes in intrahepatic lipid content and thyroid hormone parameters was evaluated in 243 individuals with data available at 12 months.

TAKEAWAY:

• Higher levels of free T3 and T3/T4 ratio were associated with increased liver fat content at baseline (P = .03 and P = .01, respectively).
• After 12 months, both the intervention and control groups showed reductions in liver fat content, along with similar reductions in free T3, total T3, T3/T4 ratio, and free T3/free T4 ratio (all P < .01).
• Thyroid stimulating hormone, T4, and free T4 levels remained stable in either group during the intervention.
• Participants who maintained higher T3 levels during the dietary intervention experienced a greater reduction in liver fat content over 12 months (Rho = −0.133; P = .039).

IN PRACTICE:

“A higher peripheral concentration of active THs [thyroid hormones] might reflect a compensatory mechanism in subjects with mildly increased IHL [intrahepatic lipid] content and early stages of MASLD [metabolic dysfunction–associated steatotic liver disease],” the authors wrote.

The study was led by Miriam Sommer-Ballarini, Charité–Universitätsmedizin Berlin, Berlin, Germany. It was published online in the European Journal of Endocrinology.

LIMITATIONS:

Participants younger than 50 years of age and with severe hepatic disease, severe substance abuse, or active cancer were excluded, which may limit the generalizability of the findings. Because the study cohort had only mildly elevated median intrahepatic lipid content at baseline, it may not be suited to address the advanced stages of metabolic dysfunction–associated steatotic liver disease. The study’s findings are based on a specific dietary intervention, which may not be applicable to other dietary patterns or populations.

The American Headache Society (AHS) has published a white paper guiding the treatment of posttraumatic headache caused by concussion in youth.

The guidance document, the first of its kind, covers risk factors for prolonged recovery, along with pharmacologic and nonpharmacologic management strategies, and supports an emphasis on multidisciplinary care, lead author Carlyn Patterson Gentile, MD, PhD, attending physician in the Division of Neurology at Children’s Hospital of Philadelphia in Pennsylvania, and colleagues reported.

“There are no guidelines to inform the management of posttraumatic headache in youth, but multiple studies have been conducted over the past 2 decades,” the authors wrote in Headache. “This white paper aims to provide a thorough review of the current literature, identify gaps in knowledge, and provide a road map for [posttraumatic headache] management in youth based on available evidence and expert opinion.”
 

Clarity for an Underrecognized Issue

According to Russell Lonser, MD, professor and chair of neurological surgery at Ohio State University, Columbus, the white paper is important because it offers concrete guidance for health care providers who may be less familiar with posttraumatic headache in youth.

“It brings together all of the previous literature ... in a very well-written way,” Dr. Lonser said in an interview. “More than anything, it could reassure [providers] that they shouldn’t be hunting down potentially magical cures, and reassure them in symptomatic management.”

Meeryo C. Choe, MD, associate clinical professor of pediatric neurology at UCLA Health in Calabasas, California, said the paper also helps shine a light on what may be a more common condition than the public suspects.

“While the media focuses on the effects of concussion in professional sports athletes, the biggest population of athletes is in our youth population,” Dr. Choe said in a written comment. “Almost 25 million children participate in sports throughout the country, and yet we lack guidelines on how to treat posttraumatic headache which can often develop into persistent postconcussive symptoms.”

This white paper, she noted, builds on Dr. Gentile’s 2021 systematic review, introduces new management recommendations, and aligns with the latest consensus statement from the Concussion in Sport Group.

Risk Factors

The white paper first emphasizes the importance of early identification of youth at high risk for prolonged recovery from posttraumatic headache. Risk factors include female sex, adolescent age, a high number of acute symptoms following the initial injury, and social determinants of health.

“I agree that it is important to identify these patients early to improve the recovery trajectory,” Dr. Choe said.

Identifying these individuals quickly allows for timely intervention with both pharmacologic and nonpharmacologic therapies, Dr. Gentile and colleagues noted, potentially mitigating persistent symptoms. Clinicians are encouraged to perform thorough initial assessments to identify these risk factors and initiate early, personalized management plans.

Initial Management of Acute Posttraumatic Headache

For the initial management of acute posttraumatic headache, the white paper recommends a scheduled dosing regimen of simple analgesics. Ibuprofen at a dosage of 10 mg/kg every 6-8 hours (up to a maximum of 600 mg per dose) combined with acetaminophen has shown the best evidence for efficacy. Provided the patient is clinically stable, this regimen should be initiated within 48 hours of the injury and maintained with scheduled dosing for 3-10 days.

If effective, these medications can subsequently be used on an as-needed basis. Careful usage of analgesics is crucial, the white paper cautions, as overadministration can lead to medication-overuse headaches, complicating the recovery process.

Secondary Treatment Options

In cases where first-line oral medications are ineffective, the AHS white paper outlines several secondary treatment options. These include acute intravenous therapies such as ketorolac, dopamine receptor antagonists, and intravenous fluids. Nerve blocks and oral corticosteroid bridges may also be considered.

The white paper stresses the importance of individualized treatment plans that consider the specific needs and responses of each patient, noting that the evidence supporting these approaches is primarily derived from retrospective studies and case reports.

“Patient preferences should be factored in,” said Sean Rose, MD, pediatric neurologist and codirector of the Complex Concussion Clinic at Nationwide Children’s Hospital, Columbus, Ohio.

Supplements and Preventive Measures

For adolescents and young adults at high risk of prolonged posttraumatic headache, the white paper suggests the use of riboflavin and magnesium supplements. Small randomized clinical trials suggest that these supplements may aid in speeding recovery when administered for 1-2 weeks within 48 hours of injury.

If significant headache persists after 2 weeks, a regimen of riboflavin 400 mg daily and magnesium 400-500 mg nightly can be trialed for 6-8 weeks, in line with recommendations for migraine prevention. Additionally, melatonin at a dose of 3-5 mg nightly for an 8-week course may be considered for patients experiencing comorbid sleep disturbances.

Targeted Preventative Therapy

The white paper emphasizes the importance of targeting preventative therapy to the primary headache phenotype.

For instance, patients presenting with a migraine phenotype, or those with a personal or family history of migraines, may be most likely to respond to medications proven effective in migraine prevention, such as amitriptyline, topiramate, and propranolol.

“Most research evidence [for treating posttraumatic headache in youth] is still based on the treatment of migraine,” Dr. Rose pointed out in a written comment.

Dr. Gentile and colleagues recommend initiating preventive therapies 4-6 weeks post injury if headaches are not improving, occur more than 1-2 days per week, or significantly impact daily functioning.

Specialist Referrals and Physical Activity

Referral to a headache specialist is advised for patients who do not respond to first-line acute and preventive therapies. Specialists can offer advanced diagnostic and therapeutic options, the authors noted, ensuring a comprehensive approach to managing posttraumatic headache.

The white paper also recommends noncontact, sub–symptom threshold aerobic physical activity and activities of daily living after an initial 24-48 hour period of symptom-limited cognitive and physical rest. Engaging in these activities may promote faster recovery and help patients gradually return to their normal routines.

“This has been a shift in the concussion treatment approach over the last decade, and is one of the most important interventions we can recommend as physicians,” Dr. Choe noted. “This is where pediatricians and emergency department physicians seeing children acutely can really make a difference in the recovery trajectory for a child after a concussion. ‘Cocoon therapy’ has been proven not only to not work, but be detrimental to recovery.”
 

Nonpharmacologic Interventions

Based on clinical assessment, nonpharmacologic interventions may also be considered, according to the white paper. These interventions include cervico-vestibular therapy, which addresses neck and balance issues, and cognitive-behavioral therapy, which helps manage the psychological aspects of chronic headache. Dr. Gentile and colleagues highlighted the potential benefits of a collaborative care model that incorporates these nonpharmacologic interventions alongside pharmacologic treatments, providing a holistic approach to posttraumatic headache management.

“Persisting headaches after concussion are often driven by multiple factors,” Dr. Rose said. “Multidisciplinary concussion clinics can offer multiple treatment approaches such as behavioral, physical therapy, exercise, and medication options.”
 

Unmet Needs

The white paper concludes by calling for high-quality prospective cohort studies and placebo-controlled, randomized, controlled trials to further advance the understanding and treatment of posttraumatic headache in children.

Dr. Lonser, Dr. Choe, and Dr. Rose all agreed.

“More focused treatment trials are needed to gauge efficacy in children with headache after concussion,” Dr. Rose said.

Specifically, Dr. Gentile and colleagues underscored the need to standardize data collection via common elements, which could improve the ability to compare results across studies and develop more effective treatments. In addition, research into the underlying pathophysiology of posttraumatic headache is crucial for identifying new therapeutic targets and clinical and biological markers that can personalize patient care.

They also stressed the importance of exploring the impact of health disparities and social determinants on posttraumatic headache outcomes, aiming to develop interventions that are equitable and accessible to all patient populations.The white paper was approved by the AHS, and supported by the National Institutes of Health/National Institute of Neurological Disorders and Stroke K23 NS124986. The authors disclosed relationships with Eli Lilly, Pfizer, Amgen, and others. The interviewees disclosed no conflicts of interest.

The Diagnosis: Microsecretory Adenocarcinoma

Microscopically, the tumor was relatively well circumscribed but had irregular borders. It consisted of microcysts and tubules lined by flattened to plump eosinophilic cells with mildly enlarged nuclei and intraluminal basophilic secretions. Peripheral lymphocytic aggregates also were seen in the mid and deep reticular dermis. Tumor necrosis, lymphovascular invasion, and notable mitotic activity were absent. Immunohistochemistry was diffusely positive for cytokeratin (CK) 7 and CK5/6. Occasional tumor cells showed variable expression of alpha smooth muscle actin, S-100 protein, and p40 and p63 antibodies. Immunohistochemistry was negative for CK20; GATA binding protein 3; MYB proto-oncogene, transcription factor; and insulinoma-associated protein ¹. A dual-color, break-apart fluorescence in situ hybridization probe identified a rearrangement of the SS18 (SYT) gene locus on chromosome 18. The nodule was excised with clear surgical margins, and the patient had no evidence of recurrent disease or metastasis at 2-year follow-up.

In recent years, there has been a growing recognition of the pivotal role played by gene fusions in driving oncogenesis, encompassing a diverse range of benign and malignant cutaneous neoplasms. These investigations have shed light on previously unknown mechanisms and pathways contributing to the pathogenesis of these neoplastic conditions, offering invaluable insights into their underlying biology. As a result, our ability to classify and diagnose these cutaneous tumors has improved. A notable example of how our current understanding has evolved is the discovery of the new cutaneous adnexal tumor microsecretory adenocarcinoma (MSA). Initially described by Bishop et al¹ in 2019 as predominantly occurring in the intraoral minor salivary glands, rare instances of primary cutaneous MSA involving the head and neck regions also have been reported.² Microsecretory adenocarcinoma represents an important addition to the group of fusion-driven tumors with both salivary gland and cutaneous adnexal analogues, characterized by a MEF2C::SS18 gene fusion. This entity is now recognized as a group of cutaneous adnexal tumors with distinct gene fusions, including both relatively recently discovered entities (eg, secretory carcinoma with NTRK fusions) and previously known entities with newly identified gene fusions (eg, poroid neoplasms with NUTM1, YAP1, or WWTR1 fusions; hidradenomatous neoplasms with CRTC1::MAML2 fusions; and adenoid cystic carcinoma with MYB, MYBL1, and/or NFIB rearrangements).³

Microsecretory adenocarcinoma exhibits a high degree of morphologic consistency, characterized by a microcystic-predominant growth pattern, uniform intercalated ductlike tumor cells with attenuated eosinophilic to clear cytoplasm, monotonous oval hyperchromatic nuclei with indistinct nucleoli, abundant basophilic luminal secretions, and a variably cellular fibromyxoid stroma. It also shows rounded borders with subtle infiltrative growth. Occasionally, pseudoepitheliomatous hyperplasia, tumor-associated lymphoid proliferation, or metaplastic bone formation may accompany MSA. Perineural invasion is rare, necrosis is absent, and mitotic rates generally are low, contributing to its distinctive histopathologic features that aid in accurate diagnosis and differentiation from other entities. Immunohistochemistry reveals diffuse positivity for CK7 and patchy to diffuse expression of S-100 in tumor cells as well as variable expression of p40 and p63. Highly specific SS18 gene translocations at chromosome 18q are useful for diagnosing MSA when found alongside its characteristic appearance, and SS18 break-apart fluorescence in situ hybridization can serve reliably as an accurate diagnostic method (Figure 1).⁴ Our case illustrates how molecular analysis assists in distinguishing MSA from other cutaneous adnexal tumors, exemplifying the power of our evolving understanding in refining diagnostic accuracy and guiding targeted therapies in clinical practice.

The differential diagnosis of MSA includes tubular adenoma, secretory carcinoma, cribriform tumor (previously carcinoma), and metastatic adenocarcinoma. Tubular adenoma is a rare benign neoplasm that predominantly affects females and can manifest at any age in adulthood. It typically manifests as a slow-growing, occasionally pedunculated nodule, often measuring less than 2 cm. Although it most commonly manifests on the scalp, tubular adenoma also may arise in diverse sites such as the face, axillae, lower extremities, or genitalia.

Notably, scalp lesions often are associated with nevus sebaceus of Jadassohn or syringocystadenoma papilliferum. Microscopically, tubular adenoma is well circumscribed within the dermis and may extend into the subcutis in some cases. Its distinctive appearance consists of variably sized tubules lined by a double or multilayered cuboidal to columnar epithelium, frequently displaying apocrine decapitation secretion (Figure 2). Cystic changes and intraluminal papillae devoid of true fibrovascular cores frequently are observed. Immunohistochemically, luminal epithelial cells express epithelial membrane antigen and carcinoembryonic antigen, while the myoepithelial layer expresses smooth muscle markers, p40, and S-100 protein. BRAF V600E mutation can be detected using immunohistochemistry, with excellent sensitivity and specificity using the anti-BRAF V600E antibody (clone VE1).⁵ Distinguishing tubular adenoma from MSA is achievable by observing its larger, more variable tubules, along with the consistent presence of a peripheral myoepithelial layer.

Secretory carcinoma is recognized as a low-grade gene fusion–driven carcinoma that primarily arises in salivary glands (both major and minor), with occasional occurrences in the breast and extremely rare instances in other locations such as the skin, thyroid gland, and lung.⁶ Although the axilla is the most common cutaneous site, diverse locations such as the neck, eyelids, extremities, and nipples also have been documented. Secretory carcinoma affects individuals across a wide age range (13–71 years).⁶ The hallmark tumors exhibit densely packed, sievelike microcystic glands and tubular spaces filled with abundant eosinophilic intraluminal secretions (Figure 3). Additionally, morphologic variants, such as predominantly papillary, papillary-cystic, macrocystic, solid, partially mucinous, and mixed-pattern neoplasms, have been described. Secretory carcinoma shares certain features with MSA; however, it is distinguished by the presence of pronounced eosinophilic secretions, plump and vacuolated cytoplasm, and a less conspicuous fibromyxoid stroma. Immunohistochemistry reveals tumor cells that are positive for CK7, SOX-10, S-100, mammaglobin, MUC4, and variably GATA-3. Genetically, secretory carcinoma exhibits distinct characteristics, commonly showing the ETV6::NTRK3 fusion, detectable through molecular techniques or pan-TRK immunohistochemistry, while RET fusions and other rare variants are less frequent.⁷

In 1998, Requena et al⁸ introduced the concept of primary cutaneous cribriform carcinoma. Despite initially being classified as a carcinoma, the malignant potential of this tumor remains uncertain. Consequently, the term cribriform tumor now has become the preferred terminology for denoting this rare entity.⁹ Primary cutaneous cribriform tumors are observed more commonly in women and typically affect individuals aged 20 to 55 years (mean, 44 years). Predominant locations include the upper and lower extremities, especially the thighs, knees, and legs, with additional cases occurring on the head and trunk. Microscopically, cribriform tumor is characterized by a partially circumscribed, unencapsulated dermal nodule composed of round or oval nuclei displaying hyperchromatism and mild pleomorphism. The defining aspect of its morphology revolves around interspersed small round cavities that give rise to the hallmark cribriform pattern (Figure 4). Although MSA occasionally may exhibit a cribriform architectural pattern, it typically lacks the distinctive feature of thin, threadlike, intraluminal bridging strands observed in cribriform tumors. Similarly, luminal cells within the cribriform tumor express CK7 and exhibit variable S-100 expression. It is recognized as an indolent neoplasm with uncertain malignant potential.

The histopathologic features of metastatic carcinomas can overlap with those of primary cutaneous tumors, particularly adnexal neoplasms.¹⁰ However, several key features can aid in the differentiation of cutaneous metastases, including a dermal-based growth pattern with or without subcutaneous involvement, the presence of multiple lesions, and the occurrence of lymphovascular invasion (Figure 5). Conversely, features that suggest a primary cutaneous adnexal neoplasm include the presence of superimposed in situ disease, carcinoma developing within a benign adnexal neoplasm, and notable stromal and/or vascular hyalinization within benign-appearing areas. In some cases, it can be difficult to determine the primary site of origin of a metastatic carcinoma to the skin based on morphologic features alone. In these cases, immunohistochemistry can be helpful. The most cost-effective and time-efficient approach to accurate diagnosis is to obtain a comprehensive clinical history. If there is a known history of cancer, a small panel of organ-specific immunohistochemical studies can be performed to confirm the diagnosis. If there is no known history, an algorithmic approach can be used to identify the primary site of origin. In all circumstances, it cannot be stressed enough that acquiring a thorough clinical history before conducting any diagnostic examinations is paramount.

The Diagnosis: Microsecretory Adenocarcinoma

Microscopically, the tumor was relatively well circumscribed but had irregular borders. It consisted of microcysts and tubules lined by flattened to plump eosinophilic cells with mildly enlarged nuclei and intraluminal basophilic secretions. Peripheral lymphocytic aggregates also were seen in the mid and deep reticular dermis. Tumor necrosis, lymphovascular invasion, and notable mitotic activity were absent. Immunohistochemistry was diffusely positive for cytokeratin (CK) 7 and CK5/6. Occasional tumor cells showed variable expression of alpha smooth muscle actin, S-100 protein, and p40 and p63 antibodies. Immunohistochemistry was negative for CK20; GATA binding protein 3; MYB proto-oncogene, transcription factor; and insulinoma-associated protein ¹. A dual-color, break-apart fluorescence in situ hybridization probe identified a rearrangement of the SS18 (SYT) gene locus on chromosome 18. The nodule was excised with clear surgical margins, and the patient had no evidence of recurrent disease or metastasis at 2-year follow-up.

In recent years, there has been a growing recognition of the pivotal role played by gene fusions in driving oncogenesis, encompassing a diverse range of benign and malignant cutaneous neoplasms. These investigations have shed light on previously unknown mechanisms and pathways contributing to the pathogenesis of these neoplastic conditions, offering invaluable insights into their underlying biology. As a result, our ability to classify and diagnose these cutaneous tumors has improved. A notable example of how our current understanding has evolved is the discovery of the new cutaneous adnexal tumor microsecretory adenocarcinoma (MSA). Initially described by Bishop et al¹ in 2019 as predominantly occurring in the intraoral minor salivary glands, rare instances of primary cutaneous MSA involving the head and neck regions also have been reported.² Microsecretory adenocarcinoma represents an important addition to the group of fusion-driven tumors with both salivary gland and cutaneous adnexal analogues, characterized by a MEF2C::SS18 gene fusion. This entity is now recognized as a group of cutaneous adnexal tumors with distinct gene fusions, including both relatively recently discovered entities (eg, secretory carcinoma with NTRK fusions) and previously known entities with newly identified gene fusions (eg, poroid neoplasms with NUTM1, YAP1, or WWTR1 fusions; hidradenomatous neoplasms with CRTC1::MAML2 fusions; and adenoid cystic carcinoma with MYB, MYBL1, and/or NFIB rearrangements).³

Microsecretory adenocarcinoma exhibits a high degree of morphologic consistency, characterized by a microcystic-predominant growth pattern, uniform intercalated ductlike tumor cells with attenuated eosinophilic to clear cytoplasm, monotonous oval hyperchromatic nuclei with indistinct nucleoli, abundant basophilic luminal secretions, and a variably cellular fibromyxoid stroma. It also shows rounded borders with subtle infiltrative growth. Occasionally, pseudoepitheliomatous hyperplasia, tumor-associated lymphoid proliferation, or metaplastic bone formation may accompany MSA. Perineural invasion is rare, necrosis is absent, and mitotic rates generally are low, contributing to its distinctive histopathologic features that aid in accurate diagnosis and differentiation from other entities. Immunohistochemistry reveals diffuse positivity for CK7 and patchy to diffuse expression of S-100 in tumor cells as well as variable expression of p40 and p63. Highly specific SS18 gene translocations at chromosome 18q are useful for diagnosing MSA when found alongside its characteristic appearance, and SS18 break-apart fluorescence in situ hybridization can serve reliably as an accurate diagnostic method (Figure 1).⁴ Our case illustrates how molecular analysis assists in distinguishing MSA from other cutaneous adnexal tumors, exemplifying the power of our evolving understanding in refining diagnostic accuracy and guiding targeted therapies in clinical practice.

The differential diagnosis of MSA includes tubular adenoma, secretory carcinoma, cribriform tumor (previously carcinoma), and metastatic adenocarcinoma. Tubular adenoma is a rare benign neoplasm that predominantly affects females and can manifest at any age in adulthood. It typically manifests as a slow-growing, occasionally pedunculated nodule, often measuring less than 2 cm. Although it most commonly manifests on the scalp, tubular adenoma also may arise in diverse sites such as the face, axillae, lower extremities, or genitalia.

Notably, scalp lesions often are associated with nevus sebaceus of Jadassohn or syringocystadenoma papilliferum. Microscopically, tubular adenoma is well circumscribed within the dermis and may extend into the subcutis in some cases. Its distinctive appearance consists of variably sized tubules lined by a double or multilayered cuboidal to columnar epithelium, frequently displaying apocrine decapitation secretion (Figure 2). Cystic changes and intraluminal papillae devoid of true fibrovascular cores frequently are observed. Immunohistochemically, luminal epithelial cells express epithelial membrane antigen and carcinoembryonic antigen, while the myoepithelial layer expresses smooth muscle markers, p40, and S-100 protein. BRAF V600E mutation can be detected using immunohistochemistry, with excellent sensitivity and specificity using the anti-BRAF V600E antibody (clone VE1).⁵ Distinguishing tubular adenoma from MSA is achievable by observing its larger, more variable tubules, along with the consistent presence of a peripheral myoepithelial layer.

TOPLINE:

The maternal and neonatal outcomes in pregnant women treated with anti–interleukin (IL)-6 therapy for COVID-19 are largely favorable, with transient neonatal cytopenia observed in around one third of the babies being the only possible adverse outcome that could be related to anti–IL-6 therapy.

METHODOLOGY:

• Despite guidance, very few pregnant women with COVID-19 are offered evidence-based therapies such as anti–IL-6 due to concerns regarding fetal safety in later pregnancy.
• In this retrospective study, researchers evaluated maternal and neonatal outcomes in 25 pregnant women with COVID-19 (mean age at admission, 33 years) treated with anti–IL-6 (tocilizumab or sarilumab) at two tertiary hospitals in London.
• Most women (n = 16) received anti–IL-6 in the third trimester of pregnancy, whereas nine received it during the second trimester.
• Maternal and neonatal outcomes were assessed through medical record reviews and maternal medicine networks, with follow-up for 12 months.
• The women included in the study constituted a high-risk population with severe COVID-19; 24 required level two or three critical care. All women were receiving at least three concomitant medications due to their critical illness.

TAKEAWAY:

• Overall, 24 of 25 women treated with IL-6 receptor antibodies survived until hospital discharge.
• The sole death occurred in a woman with severe COVID-19 pneumonitis who later developed myocarditis and cardiac arrest. The physicians believed that these complications were more likely due to severe COVID-19 rather than anti–IL-6 therapy.
• All pregnancies resulted in live births; however, 16 babies had to be delivered preterm due to COVID-19 complications.
• Transient cytopenia was observed in 6 of 19 babies in whom a full blood count was performed. All the six babies were premature, with cytopenia resolving within 7 days in four babies; one baby died from complications associated with extreme prematurity.

IN PRACTICE:

“Although the authors found mild, transitory cytopenia in some (6 of 19) exposed infants, most had been delivered prematurely due to progressive COVID-19–related morbidity, and distinguishing drug effects from similar prematurity-related effects is difficult,” wrote Steven L. Clark, MD, from the Department of Obstetrics and Gynecology, Baylor College of Medicine, Houston, in an accompanying editorial.

SOURCE:

The study was led by Melanie Nana, MRCP, from the Department of Obstetric Medicine, St Thomas’ Hospital, London, England. It was published online in The Lancet Rheumatology.

LIMITATIONS:

The study was retrospective in design, which may have introduced bias. The small sample size of 25 women may have limited the generalizability of the findings. Additionally, the study did not include a control group, which made it difficult to attribute outcomes solely to anti–IL-6 therapy. The lack of long-term follow-up data on the neonates also limited the understanding of potential long-term effects.

DISCLOSURES:

This study did not receive any funding. Some authors, including the lead author, received speaker fees, grants, or consultancy fees from academic institutions or pharmaceutical companies or had other ties with various sources.

TOPLINE:

Primary care visits within 90 days after cancer surgery are linked to a lower mortality rate in older adults. Patients with a primary care visit had a 90-day mortality rate of 0.3% compared with 3.3% for those without. 

METHODOLOGY:

• A total of 2566 patients aged 65 years or older who underwent inpatient cancer surgery between January 1, 2017, and December 31, 2019, were included in a retrospective cohort study.
• Patients were categorized on the basis of having a primary care practitioner (PCP) and whether they had a primary care visit within 90 postoperative days.
• The primary outcome was 90-day postoperative mortality, analyzed using inverse propensity weighted Kaplan-Meier curves.

TAKEAWAY: 

• Patients with a primary care visit within 90 postoperative days had a significantly lower 90-day mortality rate (0.3%) than those without a visit (3.3%; P = .001).
• Older adults without a PCP had a higher 90-day postoperative mortality rate (3.6%) than those with a PCP (2.0%; P = .01).
• Patients who had a primary care visit were more likely to be older, have a higher comorbidity score, and have higher rates of emergency department visits and readmissions.

IN PRACTICE:

“Identifying older patients with cancer who do not have a PCP in the preoperative setting is, therefore, a potential intervention point; such patients could be referred to establish primary care or prioritized for assessment in a preoperative optimization clinic,” wrote the study authors. 

SOURCE:

The study was led by Hadiza S. Kazaure, MD, of Duke University Medical Center in Durham, North Carolina. It was published online in JAMA Surgery.

LIMITATIONS:

The study was retrospective and performed at a single institution, which may limit the generalizability of the results. Coding errors were possible, and details on potential confounders such as frailty and severity of comorbidities are lacking. Mortality was low overall, limiting further adjusted and cancer-specific analyses. Data linkage between the electronic health record and Medicare and Medicaid databases was not possible, limiting analysis of data from patients with external PCPs.

DISCLOSURES:

Dr. Kazaure disclosed receiving grants from the National Cancer Institute. Additional disclosures are noted in the original article.

• Older adults without a PCP had a higher 90-day postoperative mortality rate (3.6%) than those with a PCP (2.0%; P = .01).
• Patients who had a primary care visit were more likely to be older, have a higher comorbidity score, and have higher rates of emergency department visits and readmissions.

IN PRACTICE:

“Identifying older patients with cancer who do not have a PCP in the preoperative setting is, therefore, a potential intervention point; such patients could be referred to establish primary care or prioritized for assessment in a preoperative optimization clinic,” wrote the study authors.

LIMITATIONS:

The study was retrospective and performed at a single institution, which may limit the generalizability of the results. Coding errors were possible, and details on potential confounders such as frailty and severity of comorbidities are lacking. Mortality was low overall, limiting further adjusted and cancer-specific analyses. Data linkage between the electronic health record and Medicare and Medicaid databases was not possible, limiting analysis of data from patients with external PCPs.

TOPLINE:

Primary care visits within 90 days after cancer surgery are linked to a lower mortality rate in older adults. Patients with a primary care visit had a 90-day mortality rate of 0.3% compared with 3.3% for those without. 

METHODOLOGY:

• A total of 2566 patients aged 65 years or older who underwent inpatient cancer surgery between January 1, 2017, and December 31, 2019, were included in a retrospective cohort study.
• Patients were categorized on the basis of having a primary care practitioner (PCP) and whether they had a primary care visit within 90 postoperative days.
• The primary outcome was 90-day postoperative mortality, analyzed using inverse propensity weighted Kaplan-Meier curves.

TAKEAWAY: 

• Patients with a primary care visit within 90 postoperative days had a significantly lower 90-day mortality rate (0.3%) than those without a visit (3.3%; P = .001).
• Older adults without a PCP had a higher 90-day postoperative mortality rate (3.6%) than those with a PCP (2.0%; P = .01).
• Patients who had a primary care visit were more likely to be older, have a higher comorbidity score, and have higher rates of emergency department visits and readmissions.

Despite federal legislation improving healthcare access, concerted efforts are still needed to increase evidence-based treatment for maternal perinatal mental health issues, a large study of commercially insured mothers suggested. It found that federal legislation had variable and suboptimal effect on mental health services use by delivering mothers.

In the cross-sectional study, published in JAMA Network Open, psychotherapy receipt increased somewhat during 2007-2019 among all mothers and among those diagnosed with perinatal mood and anxiety disorders (PMADs). The timeline encompassed periods before and after passage of the Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 and the Patient Protection and Affordable Care Act (ACA) of 2010.

The investigators, led by Kara Zivin, PhD, MS, MFA, a professor of psychiatry in the University of Michigan’s School of Public Health at Ann Arbor, found the results varied by policy and between the overall delivering population and the PMAD population. “We did not find a statistically significant immediate change associated with the MHPAEA or ACA in the overall delivering population, except for a steady increase in delivering women who received any psychotherapy after ACA,” Dr. Zivin and colleagues wrote.

The researchers looked at private insurance data for 837,316 deliveries among 716,052 women (64.2% White), ages 15-44 (mean 31.2), to assess changes in psychotherapy visits in the year before and after delivery. They also estimated per-visit out-of-pocket costs for the ACA in 2014 and the MHPAEA in 2010.

In the PMAD population, the MHPAEA was associated with an immediate increase in psychotherapy receipt of 0.72% (95% CI, 0.26%-1.18%; P = .002), followed by a sustained decrease of 0.05% (95% CI, 0.09%-0.02%; P = .001).

In both populations, the ACA was associated with immediate and sustained monthly increases in use of 0.77% (95% CI, 0.26%-1.27%; P = .003) and 0.07% (95% CI, 0.02%-0.12%; P = .005), respectively.

Post MHPAEA, both populations experienced a slight decrease in per-visit monthly out-of-pocket costs, while after the ACA they saw an immediate and steady monthly increase in these.

Although both policies expanded access to any psychotherapy, the greater number of people receiving visits coincided with fewer visits per person, the authors noted. “One hypothesis suggests that the number of available mental health clinicians may not have increased enough to meet the new demand; future research should better characterize this trend,” they wrote.

In addition, a lower standard cost per visit may have dampened the incentive to increase the number of mental health clinicians, they conjectured. These factors could explain why the PMAD group appeared to experience a decrease in the proportion receiving any psychotherapy after the MHPAEA’s implementation.

The findings should be reviewed in the context of the current mental health burden, the authors wrote, in which the shortage of mental health professionals means that less than 30% of mental healthcare needs are being met.

They called for more measures to mitigate the excess burden of PMADs.

This study was funded by the National Institutes of Health. Dr. Zivin had no conflicts of interest. Coauthor Dr. Dalton reported personal fees from Merck, the Society of Family Planning, Up to Date, and The Medical Letter outside of the submitted work.

Proton pump inhibitor (PPI) prophylaxis in patients undergoing mechanical ventilation can prevent upper gastrointestinal (GI) bleeding and appears to have no effect on mortality, according to a randomized trial and a systematic review led by researchers at McMaster University, Hamilton, Ontario, Canada.

Patients in the intensive care unit (ICU) who need mechanical ventilation typically are given a PPI, such as pantoprazole, to prevent upper GI bleeding caused by stress-induced stomach ulcers, but some evidence suggested that their use might increase the risk for pneumonia and death in the most severely ill patients.

As a result, recent guidelines have issued only weak recommendations for stress ulcer prophylaxis, especially with PPIs, in critically ill patients at a high risk for bleeding, Deborah Cook, MD, professor of medicine at McMaster University, and colleagues noted.

Significantly Lower Bleeding Risk

The REVISE trial, conducted in eight countries, compared pantoprazole 40 mg daily with placebo in critically ill adults on mechanical ventilation.

The primary efficacy outcome was clinically important upper GI bleeding in the ICU at 90 days, and the primary safety outcome was death from any cause at 90 days.

A total of 4821 patients in 68 ICUs were randomly assigned to the pantoprazole group or placebo group.

Clinically important upper GI bleeding occurred in 25 patients (1%) receiving pantoprazole and in 84 patients (3.5%) receiving placebo. At 90 days, 696 patients (29.1%) in the pantoprazole group died, as did 734 (30.9%) in the placebo group.

No significant differences were found on key secondary outcomes, including ventilator-associated pneumonia and Clostridioides difficile infection in the hospital.

The authors concluded that pantoprazole resulted in a significantly lower risk for clinically important upper GI bleeding than placebo, and it had no significant effect on mortality.
 

Disease Severity as a Possible Factor

The systematic review included 12 randomized controlled trials comparing PPIs with placebo or no prophylaxis for stress ulcers in a total of 9533 critically ill adults. The researchers performed meta-analyses and assessed the certainty of the evidence. They also conducted a subgroup analysis combining within-trial subgroup data from the two largest trials.

They found that PPIs were associated with a reduced incidence of clinically important upper GI bleeding (relative risk [RR], 0.51, with high certainty evidence) and may have little or no effect on mortality (RR, 0.99, with low-certainty evidence).

However, the within-trial subgroup analysis with intermediate credibility suggested that the effect of PPIs on mortality may differ based on disease severity. The results also raised the possibility that PPI use may decrease 90-day mortality in less severely ill patients (RR, 0.89) and increase mortality in more severely ill patients (RR, 1.08). The mechanisms behind this possible signal are likely multifactorial, the authors noted.

In addition, the review found that PPIs may have no effect on pneumonia, duration of ICU stay, or duration of hospital stay, and little or no effect on C difficile infection or duration of mechanical ventilation (low-certainty evidence).

“Physicians, nurses, and pharmacists working in the ICU setting will use this information in practice right away, and the trial results and the updated meta-analysis will be incorporated into international practice guidelines,” Dr. Cook said.

Both studies had limitations. The REVISE trial did not include patient-reported disability outcomes, and the results may not be generalizable to patients with unassisted breathing. The systematic review included studies with diverse definitions of bleeding and pneumonia, and with mortality reported at different milestones, without considering competing risk analyses. Patient-important GI bleeding was available in only one trial. Other potential side effects of PPIs, such as infection with multidrug-resistant organisms, were not reported.

In an editorial accompanying both studies, Samuel M. Brown, MD, a pulmonologist and vice president of research at Intermountain Health, Salt Lake City, Utah, said that the REVISE trial was “well designed and executed, with generalizable eligibility criteria and excellent experimental separation.” He said the researchers had shown that PPIs “slightly but significantly” decrease the risk of important GI bleeding and have a “decent chance” of slightly decreasing mortality in less severely ill patients during mechanical ventilation. At the same time, he noted, PPIs “do not decrease — and may slightly increase — mortality” in severely ill patients.
