Did Statin Decision-Making Just Get Harder?

The new American Heart Association Predicting Risk of cardiovascular disease EVENTs (PREVENT) equation outperforms the standard pooled cohort equation (PCE). But there is a problem. A big one, actually. 

The new score incorporates kidney function and social situation, and it eliminates race from the estimate. It was derived from larger, more modern datasets and can be applied to younger adults. 

Two luminaries in preventive cardiology recently called the PREVENT calculator a “substantial improvement over the PCE in terms of accuracy and precision of risk estimates over the entire population and within demographic subgroups.”
 

Now to the Problem of PREVENT vs PCE

A recent study comparing PREVENT and PCE found that the PREVENT equation would assign lower 10-year risks to millions of US adults. 

The authors estimated that the more accurate calculator would result in an estimated 14 million adults no longer reaching the statin eligibility risk threshold of 7.5% over 10 years. Nearly 3 million adults would also not reach the threshold for blood pressure therapy. 

Because statins and blood pressure drugs reduce cardiac events, the authors further estimated that more than 100,000 excess myocardial infarctions (MIs) would occur if the PREVENT equation was used along with the current risk thresholds for statin eligibility.

The change in eligibility induced by PREVENT would affect more men than women and a greater proportion of Black adults than White adults. 
 

The Tension of Arbitrary Thresholds

Modern cardiac therapeutics are amazing, but it’s still better to prevent an event than to treat it. 

Statin drugs reduce cardiac risk by about 20%-25% at all absolute risks. American experts chose a 10-year risk of 7.5% as the threshold where statin benefit exceed risk. The USPSTF chose 10%. But the thresholds are arbitrary and derived only by opinion. 

If your frame is population health, the more patients who take statins, the fewer cardiac events there will be. Anything that reduces statin use increases cardiac events. 

The tension occurs because a more accurate equation decreases the number of people who meet eligibility for primary prevention therapy and therefore increases the number of cardiac events. 

I write from the perspective of both a clinician and a possible patient. As a clinician, patients often ask me whether they should take a statin. (Sadly, most have not had a risk-based discussion with their clinician. But that is another column.) 

The incidence of MI or stroke in a population has no effect on either of these scenarios. I see three broad categories of patients: minimizers, maximizers, and those in between. 

I am a minimizer. I don’t worry much about heart disease. First, I won’t ignore symptoms, and I know that we have great treatments. Second, my wife, Staci, practiced hospice and palliative care medicine, and this taught me that worrying about one specific disease is folly. In the next decade, I, like anyone my age, could have many other bad things happen: cancer, trauma, infection, etc. Given these competing risks for serious disease, a PREVENT-calculated risk of 4% or a PCE-calculated risk of 8% makes no difference. I don’t like pills, and, with risks in this range, I decline statin drugs. 

Then there are the maximizers. This person wants to avoid heart disease. Maybe they have family or friends who had terrible cardiac events. This person will maximize everything to avoid heart disease. The calculated 10-year risk makes little difference to a maximizer. Whether it is 4% or 8% matters not. They will take a statin or blood pressure drugs to reduce risk to as low as possible. 

There are people between minimizers and maximizers. I am not sure that there are that many truly undecided people, but I challenge you to translate a difference of a few percent over a decade to them. I feel comfortable with numbers but struggle to sort out these small absolute differences over such a long time frame. 
 

 

 

Other Issues With Risk-Based Decisions 

Venk Murthy, MD, PhD, from the University of Michigan, wrote on X about two other issues with a risk-based decision. One is that it does not consider life-years lost. If a 50-year-old person has a fatal MI, that counts as one event. But in life-years lost, that one event is much worse than a fatal MI in a 79-year-old. Cardiac prevention, therefore, may have a greater effect in lower-risk younger people. 

Another point Dr. Murthy made is that risk and benefit are driven by many different preferences and rare events. Minimizers and maximizers come to the decision with widely disparate preferences. Risk-based decisions treat patients as if they were automatons who make decisions based simply on calculated probabilities. Clinicians know how untrue that is. 
 

Conclusion

If you carry forward the logic of being disturbed by the estimate of more MIs using the PREVENT score, then you could justify putting statins in the water — because that would reduce population estimates of MIs. 

I am not disturbed by the PREVENT score. Clinicians treat individuals, not populations. Individuals want a more accurate score. They don’t need expert-based thresholds. Clinician and patient can discuss the evidence and come up with an agreeable decision, one that is concordant with a person’s goals. The next patient may have a different decision despite seeing the same evidence. 

The tension created by this comparative study exposes the gap between population health and basic clinical care. I don’t think clinicians need to worry about populations.

Optimizing Patient Care With Teledermatology: Improving Access, Efficiency, and Satisfaction

Telemedicine interest, which was relatively quiescent prior to the COVID-19 pandemic, has surged in popularity in the past few years.1 It can now be utilized seamlessly in dermatology practices to deliver exceptional patient care while reducing costs and travel time and offering dermatologists flexibility and improved work-life balance. Teledermatology applications include synchronous, asynchronous, and hybrid platforms.2 For synchronous teledermatology, patient visits are carried out in real time with audio and video technology.3 For asynchronous teledermatology—also known as the store-and-forward model—the dermatologist receives the patient’s history and photographs and then renders an assessment and treatment plan.2 Hybrid teledermatology uses real-time audio and video conferencing for history taking, assessment and treatment plan, and patient education, with photographs sent asynchronously.3 Telemedicine may not be initially intuitive or easy to integrate into clinical practice, but with time and effort, it will complement your dermatology practice, making it run more efficiently.

Patient Satisfaction With Teledermatology

Studies generally have shown very high patient satisfaction rates and shorter wait times with teledermatology vs in-person visits; for example, in a systematic review of 15 teledermatology studies including 7781 patients, more than 80% of participants reported high satisfaction with their telemedicine visit, with up to 92% reporting that they would choose to do a televisit again.4 In a retrospective analysis of 615 Zocdoc physicians, 65% of whom were dermatologists, mean wait times were 2.4 days for virtual appointments compared with 11.7 days for in-person appointments.5 Similarly, in a retrospective single-institution study, mean wait times for televisits were 14.3 days compared with 34.7 days for in-person referrals.6

Follow-Up Visits for Nail Disorders Via Teledermatology

Teledermatology may be particularly well suited for treating patients with nail disorders. In a prospective observational study, Onyeka et al7 accessed 813 images from 63 dermatology patients via teledermatology over a 6-month period to assess distance, focus, brightness, background, and image quality; of them, 83% were rated as high quality. Notably, images of nail disorders, skin growths, or pigmentation disorders were rated as having better image quality than images of inflammatory skin conditions (odds ratio [OR], 4.2-12.9 [P<.005]).7 In a retrospective study of 107 telemedicine visits for nail disorders during the COVID-19 pandemic, patients with longitudinal melanonychia were recommended for in-person visits for physical examination and dermoscopy, as were patients with suspected onychomycosis, who required nail plate sampling for diagnostic confirmation; however, approximately half of visits did not require in-person follow-up, including those patients with confirmed onychomycosis.8 Onychomycosis patients could be examined for clinical improvement and counseled on medication compliance via telemedicine. Other patients who did not require in-person follow-ups were those with traumatic nail disorders such as subungual hematoma and retronychia as well as those with body‐focused repetitive behaviors, including habit-tic nail deformity, onychophagia, and onychotillomania.8

Patients undergoing nail biopsies to rule out malignancies or to diagnose inflammatory nail disorders also may be managed via telemedicine. Patients for whom nail biopsies are recommended often are anxious about the procedure, which may be due to portrayal of nail trauma in the media9 or lack of accurate information on nail biopsies online.10 Therefore, counseling via telemedicine about the details of the procedure in a patient-friendly way (eg, showing an animated video and narrating it11) can allay anxiety without the inconvenience, cost, and time missed from work associated with traveling to an in-person visit. In addition, postoperative counseling ideally is performed via telemedicine because complications following nail procedures are uncommon. In a retrospective study of 502 patients who underwent a nail biopsy at a single academic center, only 14 developed surgical site infections within 8 days on average (range, 5–13 days), with a higher infection risk in patients with type 2 ­diabetes mellitus (P<.0003).12

Advantages and Limitations

There are many benefits to incorporating telemedicine into dermatology practices, including reduced overhead costs, convenience and time saved for patients, and flexibility and improved work-life balance for dermatologists. In addition, because the number of in-person visits seen generally is fixed due to space constraints and work-hour restrictions, delegating follow-up visits to telemedicine can free up in-person slots for new patients and those needing procedures. However, there also are some inherent limitations to telemedicine: technology access, vision or hearing difficulties or low digital health literacy, or language barriers. In the prospective observational study by Onyeka et al7 analyzing 813 teledermatology images, patients aged 65 to 74 years sent in more clinically useful images (OR, 7.9) and images that were more often in focus (OR, 2.6) compared with patients older than 85 years.

Final Thoughts

Incorporation of telemedicine into dermatologic practice is a valuable tool for triaging patients with acute issues, improving patient care and health care access, making practices more efficient, and improving dermatologist flexibility and work-life balance. Further development of teledermatology to provide access to underserved populations prioritizing dermatologist reimbursement and progress on technologic innovations will make teledermatology even more useful in the coming years.

Follow-Up Visits for Nail Disorders Via Teledermatology

Teledermatology may be particularly well suited for treating patients with nail disorders. In a prospective observational study, Onyeka et al7 accessed 813 images from 63 dermatology patients via teledermatology over a 6-month period to assess distance, focus, brightness, background, and image quality; of them, 83% were rated as high quality. Notably, images of nail disorders, skin growths, or pigmentation disorders were rated as having better image quality than images of inflammatory skin conditions (odds ratio [OR], 4.2-12.9 [P<.005]).7 In a retrospective study of 107 telemedicine visits for nail disorders during the COVID-19 pandemic, patients with longitudinal melanonychia were recommended for in-person visits for physical examination and dermoscopy, as were patients with suspected onychomycosis, who required nail plate sampling for diagnostic confirmation; however, approximately half of visits did not require in-person follow-up, including those patients with confirmed onychomycosis.8 Onychomycosis patients could be examined for clinical improvement and counseled on medication compliance via telemedicine. Other patients who did not require in-person follow-ups were those with traumatic nail disorders such as subungual hematoma and retronychia as well as those with body‐focused repetitive behaviors, including habit-tic nail deformity, onychophagia, and onychotillomania.8

Patients undergoing nail biopsies to rule out malignancies or to diagnose inflammatory nail disorders also may be managed via telemedicine. Patients for whom nail biopsies are recommended often are anxious about the procedure, which may be due to portrayal of nail trauma in the media9 or lack of accurate information on nail biopsies online.10 Therefore, counseling via telemedicine about the details of the procedure in a patient-friendly way (eg, showing an animated video and narrating it11) can allay anxiety without the inconvenience, cost, and time missed from work associated with traveling to an in-person visit. In addition, postoperative counseling ideally is performed via telemedicine because complications following nail procedures are uncommon. In a retrospective study of 502 patients who underwent a nail biopsy at a single academic center, only 14 developed surgical site infections within 8 days on average (range, 5–13 days), with a higher infection risk in patients with type 2 ­diabetes mellitus (P<.0003).12

Advantages and Limitations

There are many benefits to incorporating telemedicine into dermatology practices, including reduced overhead costs, convenience and time saved for patients, and flexibility and improved work-life balance for dermatologists. In addition, because the number of in-person visits seen generally is fixed due to space constraints and work-hour restrictions, delegating follow-up visits to telemedicine can free up in-person slots for new patients and those needing procedures. However, there also are some inherent limitations to telemedicine: technology access, vision or hearing difficulties or low digital health literacy, or language barriers. In the prospective observational study by Onyeka et al7 analyzing 813 teledermatology images, patients aged 65 to 74 years sent in more clinically useful images (OR, 7.9) and images that were more often in focus (OR, 2.6) compared with patients older than 85 years.

Final Thoughts

Incorporation of telemedicine into dermatologic practice is a valuable tool for triaging patients with acute issues, improving patient care and health care access, making practices more efficient, and improving dermatologist flexibility and work-life balance. Further development of teledermatology to provide access to underserved populations prioritizing dermatologist reimbursement and progress on technologic innovations will make teledermatology even more useful in the coming years.

On Second Thought: The Truth About Beta-Blockers

Article Type
Changed
Fri, 08/09/2024 - 13:09

This transcript has been edited for clarity

Giving patients a beta-blocker after a myocardial infarction is standard of care. It’s in the guidelines. It’s one of the performance measures used by the American College of Cardiology (ACC) and the American Heart Association (AHA). If you aren’t putting your post–acute coronary syndrome (ACS) patients on a beta-blocker, the ACC and the AHA both think you suck. 

They are very disappointed in you, just like your mother was when you told her you didn’t want to become a surgeon because you don’t like waking up early, your hands shake when you get nervous, it’s not your fault, there’s nothing you can do about it, so just leave me alone!

The data on beta-blockers are decades old. In the time before stents, statins, angiotensin-converting enzyme inhibitors, and dual antiplatelet therapy, when patients either died or got better on their own, beta-blockers showed major benefits. Studies like the Norwegian Multicenter Study Groupthe BHAT trial, and the ISIS-1 trial proved the benefits of beta blockade. These studies date back to the 1980s, when you could call a study ISIS without controversy. 

It was a simpler time, when all you had to worry about was the Cold War, apartheid, and the global AIDS pandemic. It was a time when doctors smoked in their offices, and patients had bigger infarcts that caused large scars and systolic dysfunction. That world is no longer our world, except for the war, the global pandemic, and the out-of-control gas prices. 

The reality is that, before troponins, we probably missed most small heart attacks. Now, most infarcts are small, and most patients walk away from their heart attacks with essentially normal hearts. Do beta-blockers still matter? If you’re a fan of Cochrane reviews, the answer is yes. 

In 2021, Cochrane published a review of beta-blockers in patients without heart failure after myocardial infarction (MI). The authors of that analysis concluded, after the usual caveats about heterogeneity, potential bias, and the whims of a random universe, that, yes, beta-blockers do reduce mortality. The risk ratio for max all-cause mortality was 0.81. 

What does that mean practically? The absolute risk was reduced from 10.9% to 8.7%, a 2.2–percentage point absolute decrease and about a 20% relative drop. A little math gives us a third number: 46. That’s the number needed to treat. If you think about how many patients you admit during a typical week of critical care unit with an MI, a number needed to treat of 46 is a pretty good trade-off for a fairly inexpensive medication with fairly minimal side effects. 

Of course, these are the same people who claim that masks don’t stop the spread of COVID-19. Sure, were they the only people who thought that handwashing was the best way to stop a respiratory virus? No. We all believed that fantasy for far longer than we should have. Not everybody can bat a thousand, if by batting a thousand, you mean reflecting on how your words will impact on a broader population primed to believe misinformation because of the increasingly toxic social media environment and worsening politicization and radicalization of our politics. 

By the way, if any of you want to come to Canada, you can stay with me. Things are incrementally better here. In this day and age, incrementally better is the best we can hope for. 

Here’s the wrinkle with the Cochrane beta-blocker review: Many of the studies took place before early revascularization became the norm and before our current armamentarium of drugs became standard of care. 

Back in the day, bed rest and the power of positive thinking were the mainstays of cardiac treatment. Also, many of these studies mixed together ST-segment MI (STEMI) and non-STEMI patients, so you’re obviously going to see more benefits in STEMI patients who are at higher risk. Some of them used intravenous (IV) beta-blockers right away, whereas some were looking only at oral beta-blockers started days after the infarct. 

We don’t use IV beta-blockers that much anymore because of the risk for shock. 

Also, some studies had short-term follow-up where the benefits were less pronounced, and some studies used doses and types of beta-blockers rarely used today. Some of the studies had a mix of coronary and heart failure patients, which muddies the water because the heart failure patients would clearly benefit from being on a beta-blocker. 

Basically, the data are not definitive because they are old and don’t reflect our current standard of care. The data contain a heterogeneous mix of patients that aren’t really relevant to the question that we’re asking. The question we’re asking is, should you put all your post-MI patients on a beta-blocker routinely, even if they don’t have heart failure? 

The REDUCE-AMI trial is the first of a few trials testing, or to be more accurate, retesting, whether beta-blockers are useful after an MI. BETAMIREBOOTDANBLOCK— you’ll be hearing these names in the next few years, either because the studies get published or because they’re the Twitter handles of people harassing you online. Either/or. (By the way, I’ll be cold in my grave before I call it X.) 

For now, REDUCE-AMI is the first across the finish line, and at least in cardiology, finishing first is a good thing. This study enrolled patients with ACS, both STEMI and non-STEMI, with a post-MI ejection fraction ≥ 50%, and the result was nothing. The risk ratio for all-cause mortality was 0.94 and was not statistically significant. 

In absolute terms, that’s a reduction from 4.1% to 3.9%, or a 0.2–percentage point decrease; this translates into a number needed to treat of 500, which is 10 times higher than what the Cochrane review found. That’s if you assume that there is, in fact, a small benefit amidst all the statistical noise, which there probably isn’t. 

Now, studies like this can never rule out small effects, either positive or negative, so maybe there is a small benefit from using beta-blockers. If it’s there, it’s really small. Do beta-blockers work? Well, yes, obviously, for heart failure and atrial fibrillation — which, let’s face it, are not exactly rare and often coexist in patients with heart disease. They probably aren’t that great as blood pressure pills, but that’s a story for another day and another video. 

Yes, beta-blockers are useful pills, and they are standard of care, just maybe not for post-MI patients with normal ejection fractions because they probably don’t really need them. They worked in the pre-stent, pre-aspirin, pre-anything era. 

That’s not our world anymore. Things change. It’s not the 1980s. That’s why I don’t have a mullet, and that’s why you need to update your kitchen.

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.

Customized Dermal Curette: An Alternative and Effective Shaving Tool in Nail Surgery

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).

FIGURE 1. The customized dermal curette is crafted from a sterile disposable dermal curette with its top flattened using a needle holder and can be used to manage longitudinal melanonychia.

FIGURE 2. A, A sterile disposable dermal curette (2.0 mm) is used for excision of a pigmented lesion on the nail matrix. B, The improved curette tool achieves more precise tissue excision, leading to uniform tissue thickness and integrity.

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).

FIGURE 3. A, Histopathologically, excision of a pigmented lesion on the nail matrix with a scalpel may yield variable tissue removal, resulting in differences in tissue thickness, fragility, and completeness (H&E, original magnification ×5). B, Excision with the customized dermal curette provides more accurate tissue excision, resulting in uniform tissue thickness and integrity (H&E, original magnification ×5).

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.

FDA Approves Lymphir for R/R Cutaneous T-Cell Lymphoma

Article Type

Fri, 08/09/2024 - 13:11

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.

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.

Thyroid Hormone Balance Crucial for Liver Fat Reduction

Article Type
Changed
Fri, 08/09/2024 - 12:41

 

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.

AHS White Paper Guides Treatment of Posttraumatic Headache in Youth

Article Type
Changed
Fri, 08/09/2024 - 12:35

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 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.

Slowly Enlarging Nodule on the Neck

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.

FIGURE 1. SS18 break-apart fluorescence in situ hybridization (red and green signals split apart) can serve as an accurate diagnostic method for microsecretory adenocarcinoma.

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

FIGURE 2. Tubular adenoma has a lobular architecture surrounded by fibrous stroma; the lobules contain irregular tubular structures with a multilayered epithelial lining. Some tubules exhibit decapitation secretion, while others display papillary cellular extensions without stroma that project into lumina filled with cellular debris and eosinophilic granular material (H&E, original magnification ×100).

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.

FIGURE 3. The characteristic tumors of secretory carcinoma display tightly clustered, sievelike microcystic glands and tubular cavities enriched with brightly eosinophilic intraluminal secretions (H&E, original magnification ×100).

FIGURE 4. Cribriform tumor features interconnected epithelial cell nests with round or oval hyperchromatic nuclei, inconspicuous nucleoli, granular chromatin, and minimal eosinophilic cytoplasm, accentuated by threadlike intraluminal strands (H&E, original magnification ×100).

FIGURE 5. Metastatic carcinoma—in this case, metastatic mammary adenocarcinoma—involves the dermis, characterized by diffuse infiltration and dissection of collagen bundles, along with extensive lymphovascular invasion (H&E, original magnification ×100).

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 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.

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.

FIGURE 1. SS18 break-apart fluorescence in situ hybridization (red and green signals split apart) can serve as an accurate diagnostic method for microsecretory adenocarcinoma.

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

FIGURE 2. Tubular adenoma has a lobular architecture surrounded by fibrous stroma; the lobules contain irregular tubular structures with a multilayered epithelial lining. Some tubules exhibit decapitation secretion, while others display papillary cellular extensions without stroma that project into lumina filled with cellular debris and eosinophilic granular material (H&E, original magnification ×100).

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.

FIGURE 3. The characteristic tumors of secretory carcinoma display tightly clustered, sievelike microcystic glands and tubular cavities enriched with brightly eosinophilic intraluminal secretions (H&E, original magnification ×100).

FIGURE 4. Cribriform tumor features interconnected epithelial cell nests with round or oval hyperchromatic nuclei, inconspicuous nucleoli, granular chromatin, and minimal eosinophilic cytoplasm, accentuated by threadlike intraluminal strands (H&E, original magnification ×100).

FIGURE 5. Metastatic carcinoma—in this case, metastatic mammary adenocarcinoma—involves the dermis, characterized by diffuse infiltration and dissection of collagen bundles, along with extensive lymphovascular invasion (H&E, original magnification ×100).

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.

How Safe is Anti–IL-6 Therapy During Pregnancy?

Article Type

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.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication. A version of this article first appeared on Medscape.com.
