Newborns of pregnant women who were treated with selective serotonin reuptake inhibitors during the third trimester are almost three times as likely to develop neonatal encephalopathy (NE), although the overall risk remains extremely low, a new study finds.

The findings were presented in a poster at the 50th annual meeting of the Child Neurology Society.

“Our work showed that neonates exposed to SSRI in utero had higher risks of neonatal encephalopathy even when adjusting for confounders such as maternal mental health disorders and age. SSRIs could cause side effects such as encephalopathy in neonates, and these risks need to be balanced carefully with the potential benefits of treatment to the mother,” study lead author Marie Cornet, MD, a neonatology fellow with Benioff Children’s Hospital at the University of California, San Francisco, said in an interview.

According to Dr. Cornet, “we know that SSRI exposure in utero is associated with increased risks of respiratory distress at birth, need for positive-pressure ventilation, and an abnormal neurologic exam.” The researchers launched the new study to determine if the estimated 4%-8% of pregnant women who take SSRIs may be putting their newborns at greater risk of NE.

The researchers retrospectively tracked 305,426 infants who were born in the Kaiser Permanente Northern California health system (≥35 weeks) from 2011 to 2019. The mothers had an average age of 31 years, and approximately 34.7% were White, 34.7% of unknown race, 23.3% Asian, and 6.2% Black.

The researchers defined NE as a “5-minute APGAR score <7 and abnormal level of consciousness, activity, tone, or reflexes.”

A total of 8,024 infants (2.6%) had mothers who used SSRIs in the third trimester, and 510 (0.17%) were determined to have had NE.

After adjustment for maternal depression or anxiety, maternal age, race, and hospital, exposed neonates had 2.7 times higher odds of NE (odds ratio, 2.7).

Each 25 mg per day increase in the dose of SSRIs, as equalized to doses of sertraline (Zoloft), was linked to a significant 31% increase in the odds of developing NE (OR, 1.31).

The study doesn’t examine the benefits of SSRI treatment in pregnancy. Those taking SSRIs were much more likely to have depression during pregnancy (76.5% vs. 13.5%) and anxiety (56.7% vs. 6.9%), compared with those who did not take the drug.

The possible connection between SSRIs and NE is unclear. “SSRIs may contribute to NE by a withdrawal mechanism or by a toxicity mechanism. It is also possible that SSRIs themselves are not responsible for encephalopathy, or that the severity of maternal mental health is itself responsible for increased neonatal encephalopathy,” Dr. Cornet said. “However, we believe we adjusted our results thoroughly for that. Furthermore, in this cohort, neonates born from mothers with untreated depression were not at higher risk of encephalopathy than neonates born to mothers without depression.”

She added: “When infants have acidosis or require prolonged resuscitation after birth, they get treated with therapeutic hypothermia. This invasive treatment was shown to decrease mortality and morbidity in neonates with hypoxic-ischemic encephalopathy. However, therapeutic hypothermia may not be helpful in infants with encephalopathy due to other causes than acute hypoxia-ischemia, such as infection, inflammation, genetic conditions, or exposure to toxins. In the case of SSRIs, our results show that, while neonates often have encephalopathy, this encephalopathy is often mild and self-resolved. We did not see a statistically significant increase in acidosis or treatment with therapeutic hypothermia.”

In the future neurologists should consider SSRI use as a potential cause in cases of NE, Dr. Cornet said. “If there are no signs of hypoxic-ischemic encephalopathy – no evidence of acidosis, acute perinatal event – treatment with therapeutic hypothermia may not be indicated.”

Dr. Cornet said more research is in the works. “Studying the long-term side effect of SSRIs on neonatal brain development and injury is essential,” she said. “We plan to compare brain injury in neonates exposed and unexposed to SSRIs and examine long-term outcomes to assess if the effect of SSRI exposure is transient or has a lasting impact.”

This study was funded by the Thrasher Early Career Research Grant and by the Newborn Brain Research Innovation Award at UCSF. The authors have no relevant disclosures.

About half of patients with rheumatoid arthritis who taper or stop disease-modifying antirheumatic drugs (DMARDs) retain stable remission after 12 months, and a majority of those who do relapse regain remission when back on their original treatments, according to data from the open-label, randomized Rheumatoid Arthritis in Ongoing Remission (RETRO) study.

“Currently, 40%-50% of patients with rheumatoid arthritis reach stable remission,” as a result of factors including earlier diagnosis and a wider range of treatments, Koray Tascilar, MD, of Friedrich Alexander University Erlangen-Nuremberg (Germany) and colleagues wrote in their publication of the RETRO trial results in Lancet Rheumatology.

Previous studies have suggested that patients with RA in sustained remission may be able to taper or withdraw treatment, but data from randomized trials are limited, the researchers said.

In the RETRO trial, researchers compared three strategies for RA patients in remission, which was defined as <2.6 on the 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR). They randomized 100 adults to continue DMARDs and glucocorticoids, 102 to taper DMARDs and glucocorticoids to half their prior doses, and 101 to reduce the doses to half for 6 months and then stop DMARDs. Patients were enrolled between May 26, 2010, and May 29, 2018, from 14 treatment centers in Germany. The final analysis included 282 patients; 92 in the continuation group, 93 in the taper group, and 96 in the stop group. The mean age of the patients was 56.5 years, and 59% were women. The mean duration of RA was 7.4 years, and the mean duration of remission was 20 months.

Overall, at 12 months, 61% of the patients remained in remission without relapse; 81.2% of the continuation group, 58.6% of the taper group, and 43.3% of the stop group. Relapses occurred in 17%, 43%, and 55% of patients in the continuation, taper, and stop groups, respectively. The median times to relapse in the three groups were 30.6 weeks, 24.3 weeks, and 26.1 weeks, respectively.

Most of the relapses occurred between weeks 24 and 36 after stopping treatment, the researchers wrote. Corresponding hazard ratios for relapse were 3.02 for the taper group and 4.34 for the stop group, compared with the continuation group. In comparison to continuing treatment, the number needed to treat for one more relapse to occur during the 12-month observation period was four for tapering and three for stopping, they noted.

The study protocol called for a return to baseline treatment for any patients who relapsed in the taper and stop groups, and most patients who relapsed regained remission after restarting their baseline treatments. Among patients who had a follow-up visit after a relapse, 10 (63%) of 16 patients in the continuation group reachieved remission before the end of the study, as did 21 (62%) of 34 in the taper group and 35 (76%) of 46 in the stop group.

The most common treatments at baseline were methotrexate (76%) and tumor necrosis factor (TNF) inhibitors (32%).

The researchers also identified several baseline characteristics associated with relapse. Overall, relapse occurred more often in biologic DMARD users than in participants treated with other drugs, more often in women than men, and more often in those with a longer disease duration, higher baseline DAS28-ESR and Health Assessment Questionnaire scores, and in those who were positive for rheumatoid factor or anti–citrullinated protein antibodies.

A total of 38 serious adverse events occurred in 29 participants during the study period, but none were deemed treatment related, and none led to study withdrawal.

The study findings were limited by several factors including the lack of masking of patients and assessors and potential underestimation of disease activity, the researchers noted. Also, the study did not include radiographic data that might have been used to confirm progression; however, such data could have produced a null result and were not feasible in the study population, they wrote.

“If RETRO had been a trial to test the superiority of 100% dose continuation, compared with tapering plus rescue treatment or stopping plus rescue treatment, we would not be able to show that continuation is superior to tapering or stopping,” the researchers noted.

The study results support “an increasingly dynamic management approach in patients with rheumatoid arthritis in stable remission,” given the changing nature of RA management, that may help reduce overtreatment in many RA patients, the researchers concluded. “Furthermore, the observation that most of the patients regained remission after reintroduction of antirheumatic treatments is helpful with regard to the benefit-risk aspect of treatment reduction.”

Real-world setting serves as starting point

The RETRO study is unique in that it tried to reflect a real-life setting by enrolling patients on baseline treatment with combinations of conventional synthetic DMARDs and biologic DMARDs seen in clinical practice rather than only patients taking biologic DMARDs – primarily TNF inhibitors – as done in previous studies of tapering and stopping DMARDs, wrote Catherine L. Hill, MD, of the University of Adelaide (Australia), in an accompanying editorial. It is also “used a simple, pragmatic one-size-fits-all treatment-tapering strategy,” she wrote.

However, she emphasized that answers are needed to questions about what relapse rates are acceptable, what duration of treatment-free time is ideal, and whether benefits to the patient outweigh risks.

Dr. Hill also highlighted the issue of identifying patients who are appropriate candidates for tapering or withdrawal. Stricter remission criteria may not be feasible in routine practice, and so “the development of algorithms to guide patient selection is likely to be the most practical way forward for clinicians and patients,” she wrote.

“Contemplation of treatment tapering or discontinuation in some patients with rheumatoid arthritis is remarkable and a measure of how far treatments have advanced,” Dr. Hill wrote. “However, further work to address outstanding questions on who should taper and how best to do it is still required,” she concluded.

The study received no outside funding. Lead author Dr. Tascilar disclosed lecture fees from Gilead and Union Chimique Belge; several coauthors disclosed relationships with multiple companies outside the current study. Dr. Hill had no financial conflicts to disclose.

To the Editor:

Pityriasis rubra pilaris (PRP) is a rare inflammatory dermatosis of unknown etiology characterized by erythematosquamous salmon-colored plaques with well-demarcated islands of unaffected skin and hyperkeratotic follicles.¹ In the United States, an incidence of 1 in 3500to 5000 patients presenting to dermatology clinics has been reported.² Pityriasis rubra pilaris has several subtypes and variability in presentation that can make accurate and timely diagnosis challenging.^3-5 Herein, we present a case of PRP with complex diagnostic and therapeutic challenges.

A 22-year-old woman presented with symmetrical, well-demarcated, hyperkeratotic, erythematous plaques with a carnauba wax–like appearance on the palms (Figure 1), soles, elbows, and trunk covering approximately 5% of the body surface area. Two weeks prior to presentation, she experienced an upper respiratory tract infection without any treatment and subsequently developed redness on the palms, which became very hard and scaly. The redness then spread to the elbows, soles, and trunk. She reported itching as well as pain in areas of fissuring. Hand mobility became restricted due to thick scale.

The patient’s medical history was notable for suspected psoriasis 9 years prior, but there were no records or biopsy reports that could be obtained to confirm the diagnosis. She also reported a similar skin condition in her father, which also was diagnosed as psoriasis, but this diagnosis could not be verified.

Although the morphology of the lesions was most consistent with localized PRP, atypical psoriasis, palmoplantar keratoderma (PPK), and erythroderma progressive symmetrica (EPS) also were considered given the personal and family history of suspected psoriasis. A biopsy could not be obtained due to an insurance issue. She was started on clobetasol cream 0.05% and ointment. At 2-week follow-up, her condition remained unchanged. Empiric systemic treatment was discussed, which would potentially work for diagnoses of both PRP and psoriasis. Due to the history of psoriasis and level of discomfort, cyclosporine 300 mg once daily was started to gain rapid control of the disease. Methotrexate also was considered due to its efficacy and economic considerations but was not selected due to patient concerns about the medication.

After 10 weeks of cyclosporine treatment, our patient showed some improvement of the skin with decreased scale and flattening of plaques but not complete resolution. At this point, a biopsy was able to be obtained with prior authorization. A 4-mm punch biopsy of the right flank demonstrated a psoriasiform and papillated epidermis with multifocally capped, compact parakeratosis and minimal lymphocytic infiltrate consistent with PRP. Although EPS also was on the histologic differential, clinical history was more consistent with a diagnosis of PRP. There was some minimal improvement with cyclosporine, but with the diagnosis of PRP confirmed, a systemic retinoid became the treatment of choice. Although acitretin is the preferred treatment for PRP, given that pregnancy would be contraindicated during and for 3 years following acitretin therapy, a trial of isotretinoin 40 mg once daily was started due to its shorter half-life compared to acitretin and was continued for 3 months (Figure 2).^6,7

The diagnosis of PRP often can be challenging given the variety of clinical presentations. This case was an atypical presentation of PRP with several learning points, as our patient’s condition did not fit perfectly into any of the 6 types of PRP. The age of onset was atypical at 22 years old. Pityriasis rubra pilaris typically presents with a bimodal age distribution, appearing either in the first decade or the fifth to sixth decades of life.^3,8 Her clinical presentation was atypical for adult-onset types I and II, which typically present with cephalocaudal progression or ichthyosiform dermatitis, respectively. Her presentation also was atypical for juvenile onset in types III, IV, and V, which tend to present in younger children and with different physical examination findings.^3,8

The morphology of our patient’s lesions also was atypical for PRP, PPK, EPS, and psoriasis. The clinical presentation had features of these entities with erythema, fissuring, xerosis, carnauba wax–like appearance, symmetric scale, and well-demarcated plaques. Although these findings are not mutually exclusive, their combined presentation is atypical. Coupled with the ambiguous family history of similar skin disease in the patient’s father, the discussion of genodermatoses, particularly PPK, further confounded the diagnosis.^4,9 When evaluating for PRP, especially with any family history of skin conditions, genodermatoses should be considered. Furthermore, our patient’s remote and unverifiable history of psoriasis serves as a cautionary reminder that prior diagnoses and medical history always should be reasonably scrutinized. Additionally, a drug-induced PRP eruption also should be considered. Although our patient received no medical treatment for the upper respiratory tract infection prior to the onset of PRP, there have been several reports of drug-induced PRP.^10-12

The therapeutic challenge in this case is one that often is encountered in clinical practice. The health care system often may pose a barrier to diagnosis by inhibiting particular services required for adequate patient care. For our patient, diagnosis was delayed by several weeks due to difficulties obtaining a diagnostic skin biopsy. When faced with challenges from health care infrastructure, creativity with treatment options, such as finding an empiric treatment option (cyclosporine in this case), must be considered.

Systemic retinoids have been found to be efficacious treatment options for PRP, but when dealing with a woman of reproductive age, reproductive preferences must be discussed before identifying an appropriate treatment regimen.^1,13-15 The half-life of acitretin compared to isotretinoin is 2 days vs 22 hours.^6,16 With alcohol consumption, acitretin can be metabolized to etretinate, which has a half-life of 120 days.¹⁷ In our patient, isotretinoin was a more manageable option to allow for greater reproductive freedom upon treatment completion.

To the Editor:

Pityriasis rubra pilaris (PRP) is a rare inflammatory dermatosis of unknown etiology characterized by erythematosquamous salmon-colored plaques with well-demarcated islands of unaffected skin and hyperkeratotic follicles.¹ In the United States, an incidence of 1 in 3500to 5000 patients presenting to dermatology clinics has been reported.² Pityriasis rubra pilaris has several subtypes and variability in presentation that can make accurate and timely diagnosis challenging.^3-5 Herein, we present a case of PRP with complex diagnostic and therapeutic challenges.

A 22-year-old woman presented with symmetrical, well-demarcated, hyperkeratotic, erythematous plaques with a carnauba wax–like appearance on the palms (Figure 1), soles, elbows, and trunk covering approximately 5% of the body surface area. Two weeks prior to presentation, she experienced an upper respiratory tract infection without any treatment and subsequently developed redness on the palms, which became very hard and scaly. The redness then spread to the elbows, soles, and trunk. She reported itching as well as pain in areas of fissuring. Hand mobility became restricted due to thick scale.

The patient’s medical history was notable for suspected psoriasis 9 years prior, but there were no records or biopsy reports that could be obtained to confirm the diagnosis. She also reported a similar skin condition in her father, which also was diagnosed as psoriasis, but this diagnosis could not be verified.

Although the morphology of the lesions was most consistent with localized PRP, atypical psoriasis, palmoplantar keratoderma (PPK), and erythroderma progressive symmetrica (EPS) also were considered given the personal and family history of suspected psoriasis. A biopsy could not be obtained due to an insurance issue. She was started on clobetasol cream 0.05% and ointment. At 2-week follow-up, her condition remained unchanged. Empiric systemic treatment was discussed, which would potentially work for diagnoses of both PRP and psoriasis. Due to the history of psoriasis and level of discomfort, cyclosporine 300 mg once daily was started to gain rapid control of the disease. Methotrexate also was considered due to its efficacy and economic considerations but was not selected due to patient concerns about the medication.

After 10 weeks of cyclosporine treatment, our patient showed some improvement of the skin with decreased scale and flattening of plaques but not complete resolution. At this point, a biopsy was able to be obtained with prior authorization. A 4-mm punch biopsy of the right flank demonstrated a psoriasiform and papillated epidermis with multifocally capped, compact parakeratosis and minimal lymphocytic infiltrate consistent with PRP. Although EPS also was on the histologic differential, clinical history was more consistent with a diagnosis of PRP. There was some minimal improvement with cyclosporine, but with the diagnosis of PRP confirmed, a systemic retinoid became the treatment of choice. Although acitretin is the preferred treatment for PRP, given that pregnancy would be contraindicated during and for 3 years following acitretin therapy, a trial of isotretinoin 40 mg once daily was started due to its shorter half-life compared to acitretin and was continued for 3 months (Figure 2).^6,7

Exhaustion. Defeat. Hopelessness. Physicians, nurses, physician assistants, and nurse practitioners are overwhelmed with burnout.

The recent round of COVID-19 is more frustrating than the first, with scientific evidence supporting ways we can prevent disease and disease progression. The health care team is no longer viewed as heroes but as the enemy, fraudulently proposing a vaccine and painting a fictional story of death, though it’s all true. The daily educational battle with patients and family members creates a challenging environment that cultivates hopelessness.

Clinicians are physically exhausted from the numerous COVID cases. Gone are the medical patients we trained for, who either remain home and risk their health or lack access to medical providers because of excessive wait times. Empathy for COVID patients is being tested even more with this new surge, and without the two-way bond of trust, clinicians are running out of fuel. Anger and distrust regarding vaccination guidance dominate the interaction when patients present demanding urgent intervention, while clinicians know that more than 95% of hospitalized patients are unvaccinated.

The struggle to find the commitment to medicine and serving patients is made worse by the pandemic fog and loss of trust from patients. Every day, health care teams risk their personal well-being to provide medical care and intervention. Not by choice do we gown up, mask up, and glove up. Each time we enter a COVID patient’s room, we expose ourselves and risk our own lives and the lives of our families for the patients who have elected to ignore medical guidance.

This national wave of resistance to vaccination is spurring an exodus from health care. Physicians are retiring early and physician assistants and nurse practitioners are seeking non–patient-facing positions to improve their own wellness and balance. A national nursing shortage is impacting patients seeking care in every medical discipline. The underlying wave of exhaustion and frustration has not completely destroyed their empathy but has depleted their drive.

How can we regain this drive amid exhausting work hours and angry patients?

As much as we have heard it, we need to protect our time to recharge. The demand to pick up extra shifts and support our colleagues has affected our personal health. Setting boundaries and building time for exercise, meditation, and connecting with family is essential for survival. Mental health is key to retaining empathy and finding hope. Education is one path to reigniting the fires of critical thinking and commitment to patient care – consider precepting students to support the growth of health care teams. Memories of patient care before this pandemic give us the hope that there is light at the end of this tunnel.

Emerging data have helped to elucidate the real world experience of regorafenib vs trifluridine/tipiracil in the third-line setting. In a single-institution retrospective study, Patel and colleagues evaluated 126 patients who received trifluridine/tipiracil and 95 patients who received regorafenib. There were higher response and disease control rates seen with trifluridine/tipiracil, although median overall survival was similar (7.5 vs 7.1 months). These findings are limited by the single-institution, retrospective and non-randomized nature of the study. Also, the better-tolerated ReDOS dose-escalation schema for regorafenib was not utilized in this study, and it would be interesting to see how this novel dosing strategy compares to trifluridine/tipiracil in the real world setting.

Immunotherapy with anti-programmed death 1 (PD-1) or anti-programmed death ligand 1 (PD-L1) monoclonal antibodies has proven to be very effective in the rare group of patients with mCRC harboring deficiencies in mismatch repair, but has unfortunately largely fallen short for the vast majority of patients with mismatch repair proficient cancers. Martinelli et al. looked at adding avelumab, and anti-PD-L1 antibody, to cetuximab in an effort to rechallenge patients with RAS wild-type disease to anti-EGFR therapy in the single-arm phase 2 CAVE trial. 77 patients were treated and the median overall survival was an impressive 11.6 months, increasing to 17.3 months in patients with circulating tumor DNA (ctDNA) that was wild-type for both RAS and BRAF. This study suggests that rechallenging with anti-EGFR therapy can be effective in a ctDNA-selected population and that immunotherapy may have a role to play in this setting, although these findings would need to be confirmed in a larger, randomized phase 3 trial.

Finally, the COVID-19 pandemic has upended medical care, including oncology care. Thierry and co-workers evaluated the effect on the pandemic lockdown in France by looking at the baseline levels of ctDNA in 80 patients with newly diagnosed mCRC presenting pre-lockdown vs. post-lockdown. They showed that median ctDNA was much higher post-lockdown (119.2 vs 17.3 ng/mL), implying that delays in diagnosis related to the pandemic led to more advanced mCRC, at least in terms of ctDNA level. This study adds to the growing literature demonstrating that COVID-19 will continue to have effects on cancer care and cancer-related mortality for years to come.

When treating oromandibular dystonia with botulinum toxin injection to the lateral pterygoid muscle, an intraoral approach is the safest way to avoid injury to the maxillary artery, new research suggests.

Oromandibular dystonia causes an involuntary opening of the mouth, which can be disabling and disfiguring. Although injection of the lateral pterygoid muscle with botulinum toxin is the preferred treatment for oromandibular dystonia, a potential complication concerns the maxillary artery, which can run either lateral or medial to the lateral pterygoid muscle.

In a study of 200 Turkish patients, researchers documented significant variations between men and women in the anatomical location of the maxillary artery – and even found lateral versus medial differences on the left and right side in the same individual.

“The results showed that the maxillary artery runs lateral to the muscle in 67% of the Turkish patients,” Rezzak Yilmaz, MD, department of neurology, University of Ankara Medical School, Turkey, reported at the International Congress of Parkinson’s Disease and Movement Disorders.

Given this high rate, there is a high risk for injury “that may result in pain and hematoma” when using preauricular extraoral injections, Dr. Yilmaz and colleagues noted. Instead, they recommend an intraoral injection approach to the lateral pterygoid muscle. “However, this critical anatomical variation is still unrecognized by most clinicians performing [botulinum toxin] injections,” they wrote.
 

Significant gender differences

The maxillary artery is the largest branch of the external carotid artery.

In the current study, the researchers used magnetic resonance angiography to assess the relevant anatomy in a cohort of 200 individuals (mean age, 56.4 years; 64% women) without a history of facial trauma or movement disorders.

Results showed that the maxillary artery ran lateral to the lateral pterygoid muscle in 67% of the study population.

“This result was also more frequent in females compared with males. Also, there was a considerable variability between the left and the right side in 20% of the participants,” Dr. Yilmaz reported.

Statistically significant gender differences were found for the artery running lateral to the lateral pterygoid muscle on both sides (71.1% in women vs. 58.5% in men; P = .007) and for the artery running lateral to the lateral pterygoid muscle on just the left side (69.8% in women vs. 53.5% in men; P = .02).

In an email exchange, Dr. Yilmaz said if medical personnel are not trained to perform an intraoral approach, “imaging to visualize the path of the maxillary artery before an extraoral/transcutaneous injection can be recommended.”

“If the imaging reveals that the maxillary artery passes lateral to the muscle, then the patient needs to be referred to another center for an intraoral injection,” unless the clinician is trained for an intraoral approach, he added.
 

Useful education

Commenting on the study, Michele Tagliati, MD, director of the Movement Disorders Program at Cedars-Sinai Medical Center, Los Angeles, said the results were educational. “I didn’t know about all this variability. I was working under the assumption that the artery was medial,” said Dr. Tagliati, who was not involved with the research.

Among his large practice of about 2,000 patients, Dr. Tagliati estimated having five patients for whom he provides this type of injection – and has never encountered a problem with them.

“Maybe all my patients are medial, but now that I’m aware I’ll probably pay more attention,” Dr. Tagliati said. He does not currently perform magnetic resonance angiography before injecting them, “although maybe I should,” he said.

When asked if it is worth the time and expense to perform magnetic resonance angiography on every patient who comes in for lateral pterygoid muscle injections, Dr. Tagliati said that although he has done the injections without problems in his current patients, he may “start obtaining imaging studies to make sure that we’re not taking unnecessary risk” if the maxillary artery is lateral to the lateral pterygoid muscle in new patients.

If there is a risk, he’ll then consider talking with colleagues in oral or facial surgery. Dr. Tagliati added that the number of patients he sees with oromandibular dystonia is rather small, so this extra step would not add a lot of additional imaging.

Overall, Dr. Tagliati noted that the study outcome was significant enough to want to use it for professional education. “I can definitely tell you that I’m going to bring it to the attention of my Fellows. [Every year] I teach one or two Fellows to inject Botox,” he said.

When treating oromandibular dystonia with botulinum toxin injection to the lateral pterygoid muscle, an intraoral approach is the safest way to avoid injury to the maxillary artery, new research suggests.

Oromandibular dystonia causes an involuntary opening of the mouth, which can be disabling and disfiguring. Although injection of the lateral pterygoid muscle with botulinum toxin is the preferred treatment for oromandibular dystonia, a potential complication concerns the maxillary artery, which can run either lateral or medial to the lateral pterygoid muscle.

In a study of 200 Turkish patients, researchers documented significant variations between men and women in the anatomical location of the maxillary artery – and even found lateral versus medial differences on the left and right side in the same individual.

“The results showed that the maxillary artery runs lateral to the muscle in 67% of the Turkish patients,” Rezzak Yilmaz, MD, department of neurology, University of Ankara Medical School, Turkey, reported at the International Congress of Parkinson’s Disease and Movement Disorders.

Given this high rate, there is a high risk for injury “that may result in pain and hematoma” when using preauricular extraoral injections, Dr. Yilmaz and colleagues noted. Instead, they recommend an intraoral injection approach to the lateral pterygoid muscle. “However, this critical anatomical variation is still unrecognized by most clinicians performing [botulinum toxin] injections,” they wrote.
 

Significant gender differences

The maxillary artery is the largest branch of the external carotid artery.

In the current study, the researchers used magnetic resonance angiography to assess the relevant anatomy in a cohort of 200 individuals (mean age, 56.4 years; 64% women) without a history of facial trauma or movement disorders.

Results showed that the maxillary artery ran lateral to the lateral pterygoid muscle in 67% of the study population.

“This result was also more frequent in females compared with males. Also, there was a considerable variability between the left and the right side in 20% of the participants,” Dr. Yilmaz reported.

Statistically significant gender differences were found for the artery running lateral to the lateral pterygoid muscle on both sides (71.1% in women vs. 58.5% in men; P = .007) and for the artery running lateral to the lateral pterygoid muscle on just the left side (69.8% in women vs. 53.5% in men; P = .02).

In an email exchange, Dr. Yilmaz said if medical personnel are not trained to perform an intraoral approach, “imaging to visualize the path of the maxillary artery before an extraoral/transcutaneous injection can be recommended.”

“If the imaging reveals that the maxillary artery passes lateral to the muscle, then the patient needs to be referred to another center for an intraoral injection,” unless the clinician is trained for an intraoral approach, he added.
 

Useful education

Commenting on the study, Michele Tagliati, MD, director of the Movement Disorders Program at Cedars-Sinai Medical Center, Los Angeles, said the results were educational. “I didn’t know about all this variability. I was working under the assumption that the artery was medial,” said Dr. Tagliati, who was not involved with the research.

Among his large practice of about 2,000 patients, Dr. Tagliati estimated having five patients for whom he provides this type of injection – and has never encountered a problem with them.

“Maybe all my patients are medial, but now that I’m aware I’ll probably pay more attention,” Dr. Tagliati said. He does not currently perform magnetic resonance angiography before injecting them, “although maybe I should,” he said.

When asked if it is worth the time and expense to perform magnetic resonance angiography on every patient who comes in for lateral pterygoid muscle injections, Dr. Tagliati said that although he has done the injections without problems in his current patients, he may “start obtaining imaging studies to make sure that we’re not taking unnecessary risk” if the maxillary artery is lateral to the lateral pterygoid muscle in new patients.

If there is a risk, he’ll then consider talking with colleagues in oral or facial surgery. Dr. Tagliati added that the number of patients he sees with oromandibular dystonia is rather small, so this extra step would not add a lot of additional imaging.

Overall, Dr. Tagliati noted that the study outcome was significant enough to want to use it for professional education. “I can definitely tell you that I’m going to bring it to the attention of my Fellows. [Every year] I teach one or two Fellows to inject Botox,” he said.

There was no funding for the study. Dr. Yilmaz and Dr. Tagliati have disclosed no relevant financial relationships.

Soon after Merck announced on Oct. 1 that it would ask federal regulators for emergency use authorization (EUA) for its auspicious new COVID-19 pill, the accolades began.

Former Food and Drug Administration chief Scott Gottlieb, MD, told CNBC the drug was “a profound game changer.” Top infectious disease expert Anthony S. Fauci, MD, called the early data “impressive.” The World Health Organization termed it “certainly good news,” while saying it awaits more data.

Merck, partnering with Ridgeback Biotherapeutics on the investigational oral antiviral medicine molnupiravir, plans to submit applications to regulatory agencies worldwide, hoping to deliver the first oral antiviral medication for COVID-19. 

Interim clinical trial results show that the drug may slash the risk for hospitalization or death by 50% in those with mild to moderate COVID-19.

When the results were found to be so favorable, the study was halted at the recommendation of an independent data-monitoring committee and in consultation with the FDA.

That initial enthusiasm is now tempered with some perspective on the pros and cons. “This anticipated drug has gotten a little more hype than it deserves,” said William Schaffner, MD, professor of preventive medicine and infectious disease specialist at Vanderbilt University Medical Center in Nashville, Tenn. He and others suggest a reality check.

“It’s not exactly a home run, like penicillin for strep throat,” agreed Carl Fichtenbaum, MD, professor of infectious diseases at the University of Cincinnati, who is investigating a similar pill for a rival company, Atea, partnering with Roche. 

“But it is encouraging,” he said. “It will probably be an incremental improvement on what we have.” The fact that it can be taken at home is a plus: “Anything we can do to keep people from getting sicker is a good thing.”

“The data show in this higher risk group [those who were studied had at least one risk factor for severe COVID-19, such as age or a medical condition], it reduces the risk of advancing to severe disease by 50%,” Dr. Schaffner said. While that’s a clear benefit for half, it of course leaves the other half without benefit, he said.

Others critiqued the predicted cost of the drug. The U.S. government has already agreed to pay about $700 per patient, according to a new report from Harvard T. H. Chan School of Public Health, Boston, and King’s College Hospital, London. That analysis concluded that the actual cost of production for the 5-day course is $17.74.

“We fully expect that having an oral treatment that reduces the risk of hospitalizations will be significantly cost effective for society,” Melissa Moody, a Merck spokesperson, told this news organization. “We are optimistic that molnupiravir can become an important medicine as part of the global effort to fight the pandemic.”

Merck expects to produce 10 million courses of treatment by the end of the year, with additional doses expected to be produced in 2022, according to a company press release. Earlier in 2021, Merck finalized its agreement with the U.S. government to supply about 1.7 million courses of the drug at the $700 price, once an EUA or FDA approval is given.

Merck also has supply and purchase agreements with other governments worldwide, pending regulatory approval.
 

Study details

Details about the study findings came from a Merck press release. In the planned interim analysis, Merck and Ridgeback evaluated data from 775 patients initially enrolled in the phase 3 MOVe-OUT trial.

All adults had lab-confirmed mild to moderate COVID-19, and reported onset of symptoms within 5 days of being randomly assigned to the drug or placebo. All had at least one risk factor linked with poor disease outcome (such as older age or obesity).

The drug is a ribonucleoside and works by creating mutations in the virus’s genome, halting the ability of the virus to replicate.

Through day 29 of the study, the drug reduced the risk or hospitalization or death by about 50%. While 7.3% of those who received the drug either died or were hospitalized by day 29, 14.1% of those on placebo did, a statistically significant difference (P = .0012).

Side effects were similar in both groups, with 35% of the drug-treated and 40% of the placebo group reporting some side effect, Merck reported. Adverse drug-related events were 12% in the drug group and 11% in the placebo group. While 1.3% of the drug-treated group quit the study because of an adverse event, 3.4% of the placebo group quit.
 

Pros, cons, and unknowns

The ability to take the drug orally, and at home, is a definite plus, Dr. Schaffner said,  compared with the monoclonal antibody treatment currently approved that must be given intravenously or subcutaneously and in certain locations.

More people could be reached and helped with the option of an at-home, oral medicine, he and others agreed.

The regimen for molnupiravir is four pills, two times daily, for 5 days, even if symptoms are mild. As with other prescription drugs, “there will always be folks who don’t comply completely” with the prescribed regimen, Dr. Schaffner said. With this pill, that might be especially true if the symptoms are very mild.

The 50% reduction is not as effective as the benefit often quoted for monoclonal antibody treatment. In clinical trials of Regeneron’s monoclonal antibody treatment, the regimen reduced COVID-19–related hospitalization or death in high-risk patients by 70%.

Even so, the new pill could change the pandemic’s course, others say. “I think molnupiravir has the potential to change how we take care of people who have COVID and risk factors for developing severe disease,” Rajesh Tim Gandhi, MD, an infectious disease physician at Massachusetts General Hospital and Harvard Medical School in Boston, told this news organization. 

“What we’ll need to do, however, is make sure that people get tested quickly after they develop symptoms and, if they’re confirmed to have COVID, start on the pills within 5 days of developing symptoms,” he said, while warning that more data are needed about the drug and the trial results.

Another concern is that the promise of a pill will stall vaccination rates, with some people figuring why get vaccinated when they can obtain the pill if they do get sick.

Relying on treatment alone won’t work, Dr. Schaffner said. “Let’s [also] focus on prevention, which is the vaccine. We have to keep working both sides of the street.”

Dr. Gandhi added: “It’s important to remember that even though molnupiravir reduced the likelihood of hospitalization and death, a number of people who received the drug still got sick enough to end up in the hospital.”

Also unknown, he said, is how severe their disease was and whether they will develop long COVID.

The Merck study included only unvaccinated people. Might it work for those vaccinated people who get a breakthrough infection? “From a purely scientific perspective, there is no reason to believe molnupiravir would not work in people who are vaccinated, but the overall efficacy on top of the vaccine is likely dependent on how well they were able to mount a protective immune response to the vaccine,” Ms. Moody said. Still, Merck believes the pill could be of benefit for these infections too, she added.

As for the expected cost, Ms. Moody said that the company takes into account a number of factors in setting pricing, “but fundamentally we look at the impact of the disease, the benefits that the drug delivers to patients and to society, and at supporting ongoing drug development.”
 

On Merck’s heels: Pfizer, Roche, Atea

Pfizer is studying an antiviral pill, PF-07321332, a protease inhibitor that blocks the protease enzymes and halts replication of the virus.

In addition to studying the drug in infected patients at high risk of severe illness and in those at typical risk, Pfizer launched a phase 2-3 study in late September that will enroll people who live in the same household as a person with a confirmed, symptomatic COVID-19 infection to see if the drug can prevent disease in those who have been exposed.

Atea and Roche’s COVID pill, AT527, is in phase 3 trials as well. AT527 is an inhibitor of polymerase, an enzyme many viruses have, to stop replications. Atea is evaluating the drug to reduce disease “burden” and for both pre- and postexposure prevention.
 

Big picture: Role of COVID-19 pills

It may be necessary to target the coronavirus with more than one antiviral agent, said Dr. Fichtenbaum, a principal investigator for the AT527 trials. 

“Sometimes viruses require two or three active agents to control their replication,” he said, citing information gleaned from other viral research, such as HIV. For control of HIV infection, a cocktail or combination of antivirals is often recommended.

That may well be the case for COVID-19, Dr. Fichtenbaum said. The goal would be to attack the virus at more than one pathway.

Atea and Roche’s COVID pill, AT527, is in phase 3 trials as well. AT527 is an inhibitor of polymerase, an enzyme many viruses have, to stop replications. Atea is evaluating the drug to reduce disease “burden” and for both pre- and postexposure prevention.
 

Big picture: Role of COVID-19 pills

It may be necessary to target the coronavirus with more than one antiviral agent, said Dr. Fichtenbaum, a principal investigator for the AT527 trials. 

“Sometimes viruses require two or three active agents to control their replication,” he said, citing information gleaned from other viral research, such as HIV. For control of HIV infection, a cocktail or combination of antivirals is often recommended.

That may well be the case for COVID-19, Dr. Fichtenbaum said. The goal would be to attack the virus at more than one pathway.

A newly published consensus statement on the management of type 1 diabetes in adults addresses the unique clinical needs of the population compared with those of children with type 1 diabetes or adults with type 2 diabetes.

“The focus on adults is kind of new and it is important. ... I do think it’s a bit of a forgotten population. Whenever we talk about diabetes in adults it’s assumed to be about type 2,” document coauthor M. Sue Kirkman, MD, said in an interview.

The document covers diagnosis of type 1 diabetes, goals and targets, schedule of care, self-management education and lifestyle, glucose monitoring, insulin therapy, hypoglycemia, psychosocial care, diabetic ketoacidosis (DKA), pancreas transplant/islet cell transplantation, adjunctive therapies, special populations (pregnant, older, hospitalized), and emergent and future perspectives.

Initially presented in draft form in June at the American Diabetes Association (ADA) 81st scientific sessions, the final version of the joint ADA/EASD statement was presented Oct. 1 at the annual meeting of the European Association for the Study of Diabetes and simultaneously published in Diabetologia and Diabetes Care.

“We are aware of the many and rapid advances in the diagnosis and treatment of type 1 diabetes ... However, despite these advances, there is also a growing recognition of the psychosocial burden of living with type 1 diabetes,” writing group cochair Richard I.G. Holt, MB BChir, PhD, professor of diabetes and endocrinology at the University of Southampton, England, said when introducing the 90-minute EASD session.

“Although there is guidance for the management of type 1 diabetes, the aim of this report is to highlight the major areas that health care professionals should consider when managing adults with type 1 diabetes,” he added.

Noting that the joint EASD/ADA consensus report on type 2 diabetes has been “highly influential,” Dr. Holt said, “EASD and ADA recognized the need to develop a comparable consensus report specifically addressing type 1 diabetes.”

The overriding goals, Dr. Holt said, are to “support people with type 1 diabetes to live a long and healthy life” with four specific strategies: delivery of insulin to keep glucose levels as close to target as possible to prevent complications while minimizing hypoglycemia and preventing DKA; managing cardiovascular risk factors; minimizing psychosocial burden; and promoting psychological well-being.
 

Diagnostic algorithm

Another coauthor, J. Hans de Vries, MD, PhD, professor of internal medicine at the University of Amsterdam, explained the recommended approach to distinguishing type 1 diabetes from type 2 diabetes or monogenic diabetes in adults, which is often a clinical challenge.

This also was the topic prompting the most questions during the EASD session.

“Especially in adults, misdiagnosis of type of diabetes is common, occurring in up to 40% of patients diagnosed after the age of 30 years,” Dr. de Vries said.

Among the many reasons for the confusion are that C-peptide levels, a reflection of endogenous insulin secretion, can still be relatively high at the time of clinical onset of type 1 diabetes, but islet antibodies don’t have 100% positive predictive value.

Obesity and type 2 diabetes are increasingly seen at younger ages, and DKA can occur in type 2 diabetes (“ketosis-prone”). In addition, monogenic forms of diabetes can be disguised as type 1 diabetes.

“So, we thought there was a need for a diagnostic algorithm,” Dr. de Vries said, adding that the algorithm – displayed as a graphic in the statement – is only for adults in whom type 1 diabetes is suspected, not other types. Also, it’s based on data from White European populations.

The first step is to test islet autoantibodies. If positive, the diagnosis of type 1 diabetes can be made. If negative and the person is younger than 35 years and without signs of type 2 diabetes, testing C-peptide is advised. If that’s below 200 pmol/L, type 1 diabetes is the diagnosis. If above 200 pmol/L, genetic testing for monogenic diabetes is advised. If there are signs of type 2 diabetes and/or the person is over age 35, type 2 diabetes is the most likely diagnosis.

And if uncertainty remains, the recommendation is to try noninsulin therapy and retest C-peptide again in 3 years, as by that time it will be below 200 pmol/L in a person with type 1 diabetes.

Dr. Kirkman commented regarding the algorithm: “It’s very much from a European population perspective. In some ways that’s a limitation, especially in the U.S. where the population is diverse, but I do think it’s still useful to help guide people through how to think about somebody who presents as an adult where it’s not obviously type 2 or type 1 ... There is a lot of in-between stuff.”
 

Psychosocial support: Essential but often overlooked

Frank J. Snoek, PhD, professor of psychology at Amsterdam University Medical Centers, Vrije Universiteit, presented the section on behavioral and psychosocial care. He pointed out that diabetes-related emotional distress is reported by 20%-40% of adults with type 1 diabetes, and that the risk of such distress is especially high at the time of diagnosis and when complications develop.

About 15% of people with type 1 diabetes have depression, which is linked to elevated A1c levels, increased complication risk, and mortality. Anxiety also is very common and linked with diabetes-specific fears including hypoglycemia. Eating disorders are more prevalent among people with type 1 diabetes than in the general population and can further complicate diabetes management.

Recommendations include periodic evaluation of psychological health and social barriers to self-management and having clear referral pathways and access to psychological or psychiatric care for individuals in need. “All members of the diabetes care team have a responsibility when it comes to offering psychosocial support as part of ongoing diabetes care and education.”

Dr. Kirkman had identified this section as noteworthy: “I think the focus on psychosocial care and making that an ongoing part of diabetes care and assessment is important.”

More data needed on diets, many other areas

During the discussion, several attendees asked about low-carbohydrate diets, embraced by many individuals with type 1 diabetes.

The document states: “While low-carbohydrate and very low-carbohydrate eating patterns have become increasingly popular and reduce A1c levels in the short term, it is important to incorporate these in conjunction with healthy eating guidelines. Additional components of the meal, including high fat and/or high protein, may contribute to delayed hyperglycemia and the need for insulin dose adjustments. Since this is highly variable between individuals, postprandial glucose measurements for up to 3 hours or more may be needed to determine initial dose adjustments.”

Beyond that, Tomasz Klupa, MD, PhD, of the department of metabolic diseases, Jagiellonian University, Krakow, Poland, responded: “We don’t have much data on low-carb diets in type 1 diabetes. ... Compliance to those diets is pretty poor. We don’t have long-term follow-up and the studies are simply not conclusive. Initial results do show reductions in body weight and A1c, but with time the compliance goes down dramatically.”

“Certainly, when we think of low-carb diets, we have to meet our patients where they are,” said Amy Hess-Fischl, a nutritionist and certified diabetes care and education specialist at the University of Chicago. “We don’t have enough data to really say there’s positive long-term evidence. But we can find a happy medium to find some benefits in glycemic and weight control. ... It’s really that collaboration with that person to identify what’s going to work for them in a healthy way.”

The EASD session concluded with writing group cochair Anne L. Peters, MD, director of clinical diabetes programs at the University of Southern California, Los Angeles, summing up the many other knowledge gaps, including personalizing use of diabetes technology, the problems of health disparities and lack of access to care, and the feasibility of prevention and/or cure.  

She observed: “There is no one-size-fits-all approach to diabetes care, and the more we can individualize our approaches, the more successful we are likely to be. ... Hopefully this consensus statement has pushed the bar a bit higher, telling the powers that be that people with type 1 diabetes need and deserve the best.

“We have a very long way to go before all of our patients reach their goals and health equity is achieved. ... We need to provide each and every person the access to the care we describe in this consensus statement, so that all can prosper and thrive and look forward to a long and healthy life lived with type 1 diabetes.”

To the Editor:

A 40-year-old Somalian man presented to the dermatology clinic with lesions on the eyelids, tongue, lips, and hands of 8 years’ duration. He was a former refugee who had faced considerable stigma from his community due to his appearance. A review of systems was remarkable for decreased appetite but no weight loss. He reported no abdominal distention, early satiety, or urinary symptoms, and he had no personal history of diabetes mellitus or obesity. Physical examination demonstrated hyperpigmented velvety plaques in all skin folds and on the genitalia. Massive papillomatosis of the eyelid margins, tongue, and lips also was noted (Figure 1A). Flesh-colored papules also were scattered across the face. Punctate, flesh-colored papules were present on the volar and palmar hands (Figure 2A). Histopathology demonstrated pronounced papillomatous epidermal hyperplasia with negative human papillomavirus (HPV) type 16 and HPV-18 DNA studies. Given the appearance of malignant acanthosis nigricans with oral and conjunctival features, cutaneous papillomatosis, and tripe palms, concern for underlying malignancy was high. Malignancy workup, including upper and lower endoscopy as well as serial computed tomography scans of the chest, abdomen, and pelvis, was unrevealing.

Laboratory investigation revealed a positive Schistosoma IgG antibody (0.38 geometric mean egg count) and peripheral eosinophilia (1.09 ×10³/μL), which normalized after praziquantel therapy. With no malignancy identified over the preceding 6-month period, treatment with acitretin 50 mg daily was initiated based on limited literature support.^1-3 Treatment led to reduction in the size and number of papillomas (Figure 1B) and tripe palms (Figure 2B) with increased mobility of hands, lips, and tongue. The patient underwent oculoplastic surgery to reduce the papilloma burden along the eyelid margins. Subsequent cystoscopy 9 months after the initial presentation revealed low-grade transitional cell carcinoma of the bladder. Intraoperative mitomycin C led to tumor shrinkage and, with continued treatment with daily acitretin, dramatic improvement of all cutaneous and mucosal symptoms (Figure 1C and Figure 2C). To date, his cutaneous symptoms have resolved.

This case demonstrated a unique presentation of multiple paraneoplastic signs in bladder transitional cell carcinoma. The presence of malignant acanthosis nigricans (including oral and conjunctival involvement), cutaneous papillomatosis, and tripe palms have been individually documented in various types of gastric malignancies.⁴ Acanthosis nigricans often is secondary to diabetes and obesity, presenting with diffuse, thickened, velvety plaques in the flexural areas. Malignant acanthosis nigricans is a rare, rapidly progressive condition that often presents over a period of weeks to months; it almost always is associated with internal malignancies. It often has more extensive involvement, extending beyond the flexural areas, than typical acanthosis nigricans.⁴ Oral involvement can be either hypertrophic or papillomatous; papillomatosis of the oral mucosa was reported in over 40% of malignant acanthosis nigricans cases (N=200).⁵ Cases with conjunctival involvement are less common.⁶ Although malignant acanthosis nigricans often is codiagnosed with a malignancy, it can precede the cancer diagnosis in some cases.^7,8 A majority of cases are associated with adenocarcinomas of the gastrointestinal tract.⁴ Progressive mucocutaneous papillomatosis also is a rare paraneoplastic condition that most commonly is associated with gastric adenocarcinomas. Progressive mucocutaneous papillomatosis often presents rapidly as verrucous growths on cutaneous surfaces (including the hands and face) but also can affect mucosal surfaces such as the mouth and conjunctiva.^9-11 Tripe palms are characterized by exaggerated dermatoglyphics with diffuse palmar ridging and hyperkeratosis. Tripe palms most often are associated with pulmonary malignancies. When tripe palms are present with malignant acanthosis nigricans, they reflect up to a one-third incidence of gastrointestinal malignancy.^12,13

Despite the individual presentation of these paraneoplastic signs in a variety of malignancies, synchronous presentation is rare. A brief literature review only identified 6 cases of concurrent acanthosis nigricans, tripe palms, and progressive mucocutaneous papillomatosis with an underlying gastrointestinal malignancy.^1,11,14-17 Two additional reports described tripe palms with oral acanthosis nigricans and progressive mucocutaneous papillomatosis in metastatic gastric adenocarcinoma and renal urothelial carcinoma.^2,18 An additional case of all 3 paraneoplastic conditions was reported in the setting of metastatic cervical cancer (HPV positive).¹⁹ Per a recent case report and literature review,²⁰ there have only been 8 cases of acanthosis nigricans reported in bladder transitional cell carcinoma,^20-27 half of which have included oral malignant acanthosis nigricans.^20-23 Only one report of concurrent cutaneous and oral malignant acanthosis nigricans and triple palms in the setting of bladder cancer has been reported.²⁰ Given the extensive conjunctival involvement and cutaneous papillomatosis in our patient, ours is a rarely reported case of concurrent malignant mucocutaneous acanthosis nigricans, tripe palms, and progressive papillomatosis in transitional cell bladder carcinoma. We believe it is imperative to consider the role of this malignancy as a cause of these paraneoplastic conditions.

Although these paraneoplastic conditions rarely co-occur, our case further offers a common molecular pathway for these conditions.²⁸ In these paraneoplastic conditions, the stimulating factor is thought to be tumor growth factor α, which is structurally related to epidermal growth factor (EGF). Epidermal growth factor receptors (EGFRs) are found in the basal layer of the epidermis, where activation stimulates keratinocyte growth and leads to the cutaneous manifestation of symptoms.²⁸ Fibroblast growth factor receptor 3 mutations are found in most noninvasive transitional cell tumors of the bladder.²⁹ The fibroblast growth factor pathway is distinctly different from the tumor growth factor α and EGF pathways.³⁰ However, this association with transitional cell carcinoma suggests that fibroblast growth factor receptor 3 also may be implicated in these paraneoplastic conditions.

Our patient responded well to treatment with acitretin 50 mg daily. The mechanism of action of retinoids involves inducing mitotic activity and desmosomal shedding.³¹ Retinoids downregulate EGFR expression and activation in EGF-stimulated cells.³² We hypothesize that these oral retinoids decreased the growth stimulus and thereby improved cutaneous signs in the setting of our patient’s transitional cell cancer. Although definitive therapy is malignancy management, our case highlights the utility of adjunctive measures such as oral retinoids and surgical debulking. While previous cases have reported use of retinoids at a lower dosage than used in this case, oral lesions often have only been mildly improved with little impact on other cutaneous symptoms.^1,2 In one case of malignant acanthosis nigricans and oral papillomatosis, isotretinoin 25 mg once every 2 to 3 days led to a moderate decrease in hyperkeratosis and papillomas, but the patient was lost to follow-up.³ Our case highlights the use of higher daily doses of oral retinoids for over 9 months, resulting in marked improvement in both the mucosal and cutaneous symptoms of acanthosis nigricans, progressive mucocutaneous papillomatosis, and tripe palms. Therefore, oral acitretin should be considered as adjuvant therapy for these paraneoplastic conditions.

By reporting this case, we hope to demonstrate the importance of considering other forms of malignancies in the presence of paraneoplastic conditions. Although gastric malignancies more commonly are associated with these conditions, bladder carcinomas also can present with cutaneous manifestations. The presence of these paraneoplastic conditions alone or together rarely is reported in urologic cancers and generally is considered to be an indicator of poor prognosis. Paraneoplastic conditions often develop rapidly and occur in very advanced malignancies.⁴ The disfiguring presentation in our case also had unusual diagnostic challenges. The presence of these conditions for 8 years and nonmetastatic advanced malignancy suggest a more indolent process and that these signs are not always an indicator of poor prognosis. Future patients with these paraneoplastic conditions may benefit from both a thorough malignancy screen, including cystoscopy, and high daily doses of oral retinoids.

To the Editor:

A 40-year-old Somalian man presented to the dermatology clinic with lesions on the eyelids, tongue, lips, and hands of 8 years’ duration. He was a former refugee who had faced considerable stigma from his community due to his appearance. A review of systems was remarkable for decreased appetite but no weight loss. He reported no abdominal distention, early satiety, or urinary symptoms, and he had no personal history of diabetes mellitus or obesity. Physical examination demonstrated hyperpigmented velvety plaques in all skin folds and on the genitalia. Massive papillomatosis of the eyelid margins, tongue, and lips also was noted (Figure 1A). Flesh-colored papules also were scattered across the face. Punctate, flesh-colored papules were present on the volar and palmar hands (Figure 2A). Histopathology demonstrated pronounced papillomatous epidermal hyperplasia with negative human papillomavirus (HPV) type 16 and HPV-18 DNA studies. Given the appearance of malignant acanthosis nigricans with oral and conjunctival features, cutaneous papillomatosis, and tripe palms, concern for underlying malignancy was high. Malignancy workup, including upper and lower endoscopy as well as serial computed tomography scans of the chest, abdomen, and pelvis, was unrevealing.

Laboratory investigation revealed a positive Schistosoma IgG antibody (0.38 geometric mean egg count) and peripheral eosinophilia (1.09 ×10³/μL), which normalized after praziquantel therapy. With no malignancy identified over the preceding 6-month period, treatment with acitretin 50 mg daily was initiated based on limited literature support.^1-3 Treatment led to reduction in the size and number of papillomas (Figure 1B) and tripe palms (Figure 2B) with increased mobility of hands, lips, and tongue. The patient underwent oculoplastic surgery to reduce the papilloma burden along the eyelid margins. Subsequent cystoscopy 9 months after the initial presentation revealed low-grade transitional cell carcinoma of the bladder. Intraoperative mitomycin C led to tumor shrinkage and, with continued treatment with daily acitretin, dramatic improvement of all cutaneous and mucosal symptoms (Figure 1C and Figure 2C). To date, his cutaneous symptoms have resolved.

This case demonstrated a unique presentation of multiple paraneoplastic signs in bladder transitional cell carcinoma. The presence of malignant acanthosis nigricans (including oral and conjunctival involvement), cutaneous papillomatosis, and tripe palms have been individually documented in various types of gastric malignancies.⁴ Acanthosis nigricans often is secondary to diabetes and obesity, presenting with diffuse, thickened, velvety plaques in the flexural areas. Malignant acanthosis nigricans is a rare, rapidly progressive condition that often presents over a period of weeks to months; it almost always is associated with internal malignancies. It often has more extensive involvement, extending beyond the flexural areas, than typical acanthosis nigricans.⁴ Oral involvement can be either hypertrophic or papillomatous; papillomatosis of the oral mucosa was reported in over 40% of malignant acanthosis nigricans cases (N=200).⁵ Cases with conjunctival involvement are less common.⁶ Although malignant acanthosis nigricans often is codiagnosed with a malignancy, it can precede the cancer diagnosis in some cases.^7,8 A majority of cases are associated with adenocarcinomas of the gastrointestinal tract.⁴ Progressive mucocutaneous papillomatosis also is a rare paraneoplastic condition that most commonly is associated with gastric adenocarcinomas. Progressive mucocutaneous papillomatosis often presents rapidly as verrucous growths on cutaneous surfaces (including the hands and face) but also can affect mucosal surfaces such as the mouth and conjunctiva.^9-11 Tripe palms are characterized by exaggerated dermatoglyphics with diffuse palmar ridging and hyperkeratosis. Tripe palms most often are associated with pulmonary malignancies. When tripe palms are present with malignant acanthosis nigricans, they reflect up to a one-third incidence of gastrointestinal malignancy.^12,13

Despite the individual presentation of these paraneoplastic signs in a variety of malignancies, synchronous presentation is rare. A brief literature review only identified 6 cases of concurrent acanthosis nigricans, tripe palms, and progressive mucocutaneous papillomatosis with an underlying gastrointestinal malignancy.^1,11,14-17 Two additional reports described tripe palms with oral acanthosis nigricans and progressive mucocutaneous papillomatosis in metastatic gastric adenocarcinoma and renal urothelial carcinoma.^2,18 An additional case of all 3 paraneoplastic conditions was reported in the setting of metastatic cervical cancer (HPV positive).¹⁹ Per a recent case report and literature review,²⁰ there have only been 8 cases of acanthosis nigricans reported in bladder transitional cell carcinoma,^20-27 half of which have included oral malignant acanthosis nigricans.^20-23 Only one report of concurrent cutaneous and oral malignant acanthosis nigricans and triple palms in the setting of bladder cancer has been reported.²⁰ Given the extensive conjunctival involvement and cutaneous papillomatosis in our patient, ours is a rarely reported case of concurrent malignant mucocutaneous acanthosis nigricans, tripe palms, and progressive papillomatosis in transitional cell bladder carcinoma. We believe it is imperative to consider the role of this malignancy as a cause of these paraneoplastic conditions.

Although these paraneoplastic conditions rarely co-occur, our case further offers a common molecular pathway for these conditions.²⁸ In these paraneoplastic conditions, the stimulating factor is thought to be tumor growth factor α, which is structurally related to epidermal growth factor (EGF). Epidermal growth factor receptors (EGFRs) are found in the basal layer of the epidermis, where activation stimulates keratinocyte growth and leads to the cutaneous manifestation of symptoms.²⁸ Fibroblast growth factor receptor 3 mutations are found in most noninvasive transitional cell tumors of the bladder.²⁹ The fibroblast growth factor pathway is distinctly different from the tumor growth factor α and EGF pathways.³⁰ However, this association with transitional cell carcinoma suggests that fibroblast growth factor receptor 3 also may be implicated in these paraneoplastic conditions.

Our patient responded well to treatment with acitretin 50 mg daily. The mechanism of action of retinoids involves inducing mitotic activity and desmosomal shedding.³¹ Retinoids downregulate EGFR expression and activation in EGF-stimulated cells.³² We hypothesize that these oral retinoids decreased the growth stimulus and thereby improved cutaneous signs in the setting of our patient’s transitional cell cancer.

The common-cold viruses rhinovirus (RV) and enterovirus (EV) continued to circulate among children during the COVID-19 pandemic while there were sharp declines in influenza, respiratory syncytial virus (RSV), and other respiratory viruses, new data indicate.

Researchers used data from the Centers for Disease Control and Prevention’s New Vaccine Surveillance Network. The cases involved 37,676 children in seven geographically diverse U.S. medical centers between December 2016 and January 2021. Patients presented to emergency departments or were hospitalized with RV, EV, and other acute respiratory viruses.

The investigators found that the percentage of children in whom RV/EV was detected from March 2020 to January 2021 was similar to the percentage during the same months in 2017-2018 and 2019-2020. However, the proportion of children infected with influenza, RSV, and other respiratory viruses combined dropped significantly in comparison to the three prior seasons.
