Endometriosis is defined as the presence of endometrial tissue outside of the uterine cavity, commonly occurring in women of reproductive age. The condition usually affects the adnexa (ovaries, Fallopian tubes, and associated ligaments and connective tissue) but can also be seen in extrapelvic structures.

Cutaneous endometriosis is an uncommon subtype that accounts for 1% of endometriosis cases and occurs when endometrial tissue is found on the surface of the skin. It is divided into primary and secondary cutaneous endometriosis. The etiology of primary cutaneous endometriosis is idiopathic, while the secondary form is believed to be a consequence of abdominal or pelvic procedures that may lead to seeding of endometrial tissue on the skin. In the case of our patient, it appears that her laparoscopic procedure 2 years ago was the cause of endometrial seeding in the umbilicus.

Clinically, the condition may present with a palpable mass, cyclic pain, and bloody discharge from the affected area. Due to the rarity of cutaneous endometriosis, it may be hard to distinguish from other diagnoses such as keloids, dermatofibromas, hernias, or cutaneous metastasis of cancers (Sister Mary Joseph nodules).

The definitive diagnosis can be made by biopsy and histopathological assessment showing a mixture of endometrial glands and stromal tissue. Imaging studies such as computed tomography (CT) scan and magnetic resonance imaging (MRI) are helpful in excluding more common diagnoses such as hernia or cutaneous metastasis. In this patient, the mass was surgically excised. Histopathological assessment established the diagnosis of cutaneous endometriosis.

Treatment options include surgical excision and medical therapy. Medical therapy entails the use of hormonal agents such as gonadotropin-releasing hormone agonists, danazol (a pituitary gonadotropin inhibitor), and oral contraceptives, which reduce the cyclical proliferation of endothelial tissue. These agents can be used preoperatively to reduce the size of the cutaneous mass before surgical excision, or as an alternative treatment for patients who wish to avoid surgery. The rate of recurrence is observed to be higher with medical therapy rather than surgical treatment.

An influential panel is seeking an increase in Medicare’s 2025 payments for clinicians, adding to pressure on Congress to reconsider how the largest US purchaser of health services pays for office visits and related care of the nation’s older citizens and those with disabilities.

The Medicare Payment Advisory Commission (MedPAC) on Thursday voted unanimously in favor of a two-part recommendation on changes to the 2025 physician fee schedule:

• An increase in the base rate equal to half of the projected change in the Medicare Economic Index (MEI). Recent estimates have projected a 2.6% increase in MEI for 2025, which is intended to show how inflation affects the costs of running a medical practice.
• The creation of a safety-net add-on payment under the physician fee schedule to cover care of people with low incomes.

These recommendations echo the calls MedPAC made in a 2023 report to Congress. 

Lawmakers and the Centers for Medicare and Medicaid Services (CMS) rely on MedPAC’s work in deciding how much to pay for services. About 1.3 million clinicians bill Medicare for their work, including about 670,000 physicians.

Thursday’s MedPAC vote comes amid continuing uncertainty about how much the federal government will actually pay clinicians this year through the physician fee schedule.

There are serious efforts underway to undo cuts already demanded by previously passed federal law. In an email, Rep. Larry Buchson, MD, (R-IN) said he remains committed to “eliminating the full 3.37% cut this year while also working toward a permanent solution to halt the downward spiral of physician reimbursement.”

“The Medicare payment cut to physicians will impede patients’ access to care and further accelerate the current path toward consolidation, physician burnout, and closure of medical practices,” Buchson told this news organization. “It’s past time that Congress provides much needed and deserved stability for America’s doctors.”

Congress this month is attempting to complete overdue budget legislation needed to fund federal operations for fiscal 2024, which began October 1, 2023. The pending expiration of a short-term stopgap continuing resolution could provide a vehicle that could also carry legislation that would address the physician fee schedule.

In a Thursday statement, Jesse M. Ehrenfeld, MD, MPH, president of the American Medical Association, commended MedPAC for its recommendations and urged lawmakers to act.

“Long-term reforms from Congress are overdue to close the unsustainable gap between what Medicare pays physicians and the actual costs of delivering high-quality care,” Dr. Ehrenfeld said. “When adjusted for inflation in practice costs, Medicare physician pay declined 26% from 2001 to 2023.”
 

Continual Struggles

Congress has struggled for years in its attempts to set Medicare payments for office visits and other services covered by the physician fee schedule. A 1990s budget law set the stage for what proved to be untenable reductions in payment through the sustainable growth rate mechanism.

Between 2003 through April 2014, lawmakers passed “doc-fix” legislation 17 times to block the slated cuts, according to the Congressional Research Service. In 2015, Congress passed an intended overhaul of the physician fee schedule through the Medicare Access and CHIP Reauthorization Act (MACRA). As part of this law, Congress eliminated a base automatic inflation adjuster for the physician fee schedule.

In recent years, Congress has acted repeatedly to address MACRA’s mandates for flat base pay. MedPAC and members of both parties in Congress have called for a broad new look at how Medicare pays physicians. 

At Thursday’s meeting, MedPAC member Lawrence Casalino, MD, PhD, MPH, noted that the struggles to keep up with inflation and the “unpredictability of what the payment rates are going to be from year to year really do affect physician morale.”

Infection with COVID-19 conferred a nearly twofold risk of developing alopecia areata (AA), results from a large analysis of Korean patients demonstrated.

“There is a growing number of reports on new onset, exacerbation, and recurrence of AA after COVID-19,” corresponding author Jin Park, MD, PhD, of the department of dermatology at Jeonbuk National University Medical School, South Korea, and colleagues wrote in a research letter published online January 10, 2024, in JAMA Dermatology. “However, evidence supporting an association between COVID-19 and AA is limited.”

To investigate the association between COVID-19 and AA, the researchers used data from the Korea Disease Control and Prevention Agency–COVID-19–National Health Insurance Service cohort to conduct a propensity score–matched, nationwide, population-based cohort study from October 8, 2020, to September 30, 2021. They used Cox proportional hazards regression to calculate the incidence, prevalence, and adjusted hazard ratios (AHRs) for AA.

The cohort consisted of 259,369 patients with COVID-19 and 259,369 uninfected controls. The researchers observed an increased risk of telogen effluvium in patients with COVID-19 compared with the uninfected controls (AHR, 6.40; 95% CI, 4.92-8.33), while the incidence of epidermal cysts, benign skin tumors, and other negative control outcomes did not differ between groups.

Meanwhile, the incidence of AA in patients with COVID-19 was significantly higher compared with the uninfected controls (43.19 per 10,000 person-years [PY]), regardless of clinical subtype. This translated into an AHR of 1.82 (95% CI, 1.60-2.07). In other findings, the incidence of patchy AA and alopecia totalis and alopecia universalis (AT/AU) was 35.94 and 7.24 per 10,000 PY in patients with COVID-19 compared with 19.43 and 4.18 per 10,000 PY in uninfected controls, respectively.

“These findings support the possible role of COVID-19 in AA occurrence and exacerbation, although other environmental factors, such as psychological stress, may have also contributed to AA development during the pandemic,” the authors concluded. “Plausible mechanisms of AA following COVID-19 include antigenic molecular mimicry between SARS-CoV-2 and hair follicle autoantigens, cytokine shifting, and bystander activation.”

They acknowledged certain limitations of the analysis, including the potential for detection or misclassification bias and the fact that it did not evaluate causality between the two conditions.

Shari Lipner, MD, PhD, associate professor of dermatology at Weill Cornell Medicine, New York, who was asked to comment on the study, said that strengths of the study include the large sample size, and the use of positive and negative outcome controls, and that the incidence and prevalence of AA in Korea was stable during the prepandemic period. “A weakness of the study is that all alopecia areata cases may not have necessarily been confirmed,” Dr. Lipner told this news organization.

“Based on this study, dermatologists may consider AA in the differential diagnosis for a patient presenting with hair loss with recent COVID-19 diagnosis,” she added, noting that the potential for prevention of AA flares is also a reason to recommend COVID-19 vaccination for patients with a history of AA.

Christine Ko, MD, professor of dermatology and pathology at Yale University, New Haven, Connecticut, who was also asked to comment on the study, said that while the analysis suggests a definite epidemiologic association between COVID-19 and AA, “any causal relationship needs further study.” She added that she has no specific advice for patients who develop AA following a COVID-19 infection. “Any conversation about AA can be difficult because there is no way to prognosticate if someone will just have one small, localized area of hair loss,” or several small areas, versus loss of all hair on the head or even the body as well, Dr. Ko explained.

The study was supported with grants from the National Research Foundation of the Korean Government and the Ministry of Health and Welfare, Republic of Korea. The authors, as well as Dr. Lipner and Dr. Ko, reported having no relevant disclosures.

Diagnosis: Infection-induced psoriasis (guttate-type, induced by streptococcal intertrigo)

Psoriasis is a chronic inflammatory disorder characterized by well-defined, scaly, erythematous plaques. Guttate psoriasis is a distinct variant of psoriasis that is more common in children and adolescents. Guttate psoriasis usually presents with multiple, scattered, small, drop-like (“guttate”), scaly, erythematous papules and plaques. Guttate psoriasis may be triggered by infections, most commonly recent streptococcal infections.

The pathophysiology of psoriasis involves an interplay between genetic and environmental factors. Guttate psoriasis is a chronic T-cell–mediated inflammatory disease in which there is an altered balance between T-helper-1 (TH1) and TH2 cells, transcription factor genes, and their products. HLA B-13, B-17, and Cw6 are human leukocyte antigen alleles implicated in genetic susceptibility. It is hypothesized that streptococcal infection precipitates guttate psoriasis by streptococcal superantigen–driven activation of cutaneous lymphocyte-associated antigen (CLA)–positive lymphocytes. It has been shown that streptococcal exotoxins and streptococcal M proteins act as superantigens.

Diagnosis is often made clinically based on characteristic physical findings and a possible preceding history of streptococcal infection. In patients with streptococcal infection, culture from an appropriate site and measurement of serum antistreptococcal antibody titers (for example, anti-DNase, antihyaluronidase and antistreptolysin-O) can help. A skin biopsy is usually not necessary but may be considered.

This patient presented with intertrigo of the neck and axillae at the time of presentation with the papulosquamous rash. Culture of the intertrigo yielded 4+ Group A beta streptococcus.
 

Treatment

Although there is currently no cure for guttate psoriasis, various treatment options can relieve symptoms and clear skin lesions, and infection-triggered lesions may remit, usually within several months. However, guttate psoriasis may persist and progress to chronic plaque psoriasis. Many treatment options are based mainly on clinical trials targeted for plaque psoriasis treatment.

For mild psoriasis, topical corticosteroids are first-line treatment. Other topical steroids include vitamin D analogs (calcipotriene), topical retinoids (tazarotene), topical calcineurin inhibitors (tacrolimus and pimecrolimus), and newer non-steroidal anti-inflammatory agents (roflumilast or tapinarof), neither approved yet in this young age group. In more severe cases, phototherapy with UVB light, traditional systemic immunosuppressive agents (methotrexate, cyclosporine) or targeted biologic therapies may be considered.
 

Differential Diagnosis

The differential diagnosis may include generalized intertrigo, pityriasis rubra pilaris, tinea corporis, atopic dermatitis, and staphylococcal scalded skin syndrome. Guttate psoriasis can be distinguished by history and physical exam. Further studies such as potassium hydroxide (KOH) scrapings may be helpful in ruling out the other disorders.

Intertrigo is an inflammatory condition of the flexural surfaces irritated by warm temperatures, friction, moisture, and poor ventilation that is commonly associated with Candida infection and/or streptococcal infection. Candidal intertrigo can present with erythematous patches or plaques in an intertriginous area that may develop erosions, macerations, fissures, crust, and weeping. Satellite papules and pustules are pathognomonic for Candida species. Streptococcal intertrigo usually presents with bright red color and may be painful or pruritic. Perianal streptococcal infection is reported as a trigger of guttate psoriasis in pediatric patients.

Pityriasis rubra pilaris is a rare inflammatory papulosquamous disorder with an unknown etiology. Red-orange papules and plaques, hyperkeratotic follicular papules, and palmoplantar hyperkeratosis are primary features. Diagnosis is based on clinical and histopathology. Pityriasis rubra pilaris is self-limited and asymptomatic in many cases. Treatment may not be required, but combination therapy with topical agents includes emollients, keratolytic agents (for example, urea, salicylic acid, alpha-hydroxy acids), topical corticosteroids, tazarotene, and topical calcineurin inhibitors. Systemic agents include oral retinoids and methotrexate.

Atopic dermatitis is a chronic inflammatory skin disease that involves genetic and environmental factors, leading to abnormalities in the epidermis and the immune system presenting with its typical morphology and distribution. The morphology of eczematous lesions is distinct from papulosquamous lesions of psoriasis.

Staphylococcal scalded skin syndrome is a toxin-mediated skin disorder which presents with denuded, peeling skin due to epidermolytic exotoxin producing Staphylococcus species. Fever, erythematous rash, malaise, skin pain, and irritability presents initially. Progressive desquamation with accentuation in folds is typical, with progression usually within 1-2 days. Systemic antibiotics covering Staphylococcus should be administered early. Emollients and nonadherent dressings should be applied to affected areas to promote healing. Supportive care includes dehydration management, temperature regulation, and nutrition. Skin desquamation usually occurs within 5 days with resolution within 2 weeks.

This infant displayed streptococcal intertrigo which triggered an early presentation of guttate psoriasis. The patient was managed with completion of a course of oral cephalexin, midstrength topical corticosteroids to the truncal lesions, and mild topical corticosteroids to the face and diaper area with good clinical response.

Diagnosis: Infection-induced psoriasis (guttate-type, induced by streptococcal intertrigo)

Psoriasis is a chronic inflammatory disorder characterized by well-defined, scaly, erythematous plaques. Guttate psoriasis is a distinct variant of psoriasis that is more common in children and adolescents. Guttate psoriasis usually presents with multiple, scattered, small, drop-like (“guttate”), scaly, erythematous papules and plaques. Guttate psoriasis may be triggered by infections, most commonly recent streptococcal infections.

The pathophysiology of psoriasis involves an interplay between genetic and environmental factors. Guttate psoriasis is a chronic T-cell–mediated inflammatory disease in which there is an altered balance between T-helper-1 (TH1) and TH2 cells, transcription factor genes, and their products. HLA B-13, B-17, and Cw6 are human leukocyte antigen alleles implicated in genetic susceptibility. It is hypothesized that streptococcal infection precipitates guttate psoriasis by streptococcal superantigen–driven activation of cutaneous lymphocyte-associated antigen (CLA)–positive lymphocytes. It has been shown that streptococcal exotoxins and streptococcal M proteins act as superantigens.

Diagnosis is often made clinically based on characteristic physical findings and a possible preceding history of streptococcal infection. In patients with streptococcal infection, culture from an appropriate site and measurement of serum antistreptococcal antibody titers (for example, anti-DNase, antihyaluronidase and antistreptolysin-O) can help. A skin biopsy is usually not necessary but may be considered.

This patient presented with intertrigo of the neck and axillae at the time of presentation with the papulosquamous rash. Culture of the intertrigo yielded 4+ Group A beta streptococcus.
 

Treatment

Although there is currently no cure for guttate psoriasis, various treatment options can relieve symptoms and clear skin lesions, and infection-triggered lesions may remit, usually within several months. However, guttate psoriasis may persist and progress to chronic plaque psoriasis. Many treatment options are based mainly on clinical trials targeted for plaque psoriasis treatment.

For mild psoriasis, topical corticosteroids are first-line treatment. Other topical steroids include vitamin D analogs (calcipotriene), topical retinoids (tazarotene), topical calcineurin inhibitors (tacrolimus and pimecrolimus), and newer non-steroidal anti-inflammatory agents (roflumilast or tapinarof), neither approved yet in this young age group. In more severe cases, phototherapy with UVB light, traditional systemic immunosuppressive agents (methotrexate, cyclosporine) or targeted biologic therapies may be considered.

The differential diagnosis may include generalized intertrigo, pityriasis rubra pilaris, tinea corporis, atopic dermatitis, and staphylococcal scalded skin syndrome. Guttate psoriasis can be distinguished by history and physical exam. Further studies such as potassium hydroxide (KOH) scrapings may be helpful in ruling out the other disorders.

Two doses of the recombinant zoster vaccine (RZV) are effective against herpes zoster (HZ) for 4 years after vaccination, according to a new study published in Annals of Internal Medicine.

Findings from the prospective cohort study showed that people who received two doses of the vaccine, regardless of when they received their second dose, experienced 79% vaccine effectiveness (VE) during the first year, with effectiveness decreasing to 73% by year 4. By contrast, the rate of effectiveness during the first year was 70% for people who received a single dose, falling to 52% effectiveness by year 4.

The findings also showed that the rate of effectiveness was 65% for those taking corticosteroids.

The study was conducted between 2018 and 2022 using data from the Vaccine Safety Datalink, a collaboration between the US Centers for Disease Control and Prevention (CDC) and nine healthcare systems across the country.

Researchers evaluated the incidence of HZ, as determined by a diagnosis and prescription for antiviral medication within 7 days of diagnosis, and monitored RZV status over time.

The findings may quell fears that waiting too long for the second dose reduces the effectiveness of the herpes vaccine, according to Nicola Klein, MD, PhD, director of the Vaccine Study Center at Kaiser Permanente in Oakland, California, who led the study.

The long-term efficacy of the vaccine is especially important because older adults are now living much longer than in previous years, according to Alexandra Tien, MD, a family physician at Medical Associates of Rhode Island in Providence.

“People live these days into their 80s and even 90s,” Dr. Tien said. “That’s a large number of years to need protection for, so it’s really important to have a long-lasting vaccine.”

The CDC currently recommends two doses of RZV separated by 2-6 months for patients aged 50 years and older. Adults older than 19 years who are immunocompromised should receive two doses of RZV separated by 1-2 months, the agency said.

According to Dr. Klein, research does not show whether VE for RZV wanes after 4 years. But interim findings from another study following people in clinical trials found VE levels remained high after 7 years.

The risk for HZ increases with age, reaching a lifetime risk of 50% among adults aged 85 years. Complications like postherpetic neuralgia (PHN) — characterized by long-term tingling, numbness, and disabling pain at the site of the rash — can interfere with the quality of life and ability to function in older adults. The CDC estimates that up to 18% of people with shingles experience PHN, and the risk increases with age.

Just like with any other vaccine, patients sometimes have concerns about the potential side effects of RZV, said Dr. Tien. But those effects, such as muscle pain, nausea, and fever, are mild compared to shingles.

“I always tell patients, with any vaccine, immunization is one of the biggest bangs for your buck in healthcare because you’re preventing a problem,” Dr. Tien said.

This study was funded by the CDC through contracts with participating sites. Study authors reported no disclosures. Dr. Tien reported no disclosures.

Key clinical point: The majority of tralokinumab-treated patients with moderate-to-severe atopic dermatitis (AD) attained physician- and patient-reported outcomes over 32 weeks of observation, highlighting the multidimensional efficacy of tralokinumab in real-world settings.

Major finding: The proportion of patients achieving a ≥75% improvement in the baseline Eczema Area and Severity Index (EASI) score increased significantly from 42% at week 4 to 76% at week 32 (P = .0075). A similar trend was observed for patient-reported outcomes. At week 16, at least one real-world therapeutic endpoint was achieved by 88% of patients treated with tralokinumab.

Study details: Findings are from a multicenter real-world retrospective cohort study including 194 patients with moderate-to-severe AD who were treated with tralokinumab for ≥16 weeks.

Disclosures: This study did not receive any funding. Several authors declared serving as speakers, consultants, or scientific advisors; receiving personal fees, speaker’s honoraria, or travel support, or having other ties with various pharmaceutical companies.

Key clinical point: Abrocitinib treatment over 12 weeks significantly decreased the cutaneous expression of selected genes involved in inflammation, epidermal hyperplasia, and T-helper (Th) 2 and Th22 immune responses in patients with moderate-to-severe atopic dermatitis (AD).

Major finding: Compared with placebo, 12-week abrocitinib treatment led to a dose-dependent reduction in the cutaneous expression of genes involved in inflammation (MMP-12), epidermal hyperplasia (KRT16), Th2 (CCL17 and CCL18), and Th22 (S100A8, S100A9, and S100A12) responses (all P < .05).

Study details: Findings are from the phase 2a JADE MOA trial including patients with moderate-to-severe AD who were randomly assigned to receive 100 mg (n = 16) or 200 mg (n = 14) abrocitinib monotherapy or placebo (n = 16) daily for 12 weeks.

Disclosures: This study was sponsored by Pfizer Inc. Several authors declared being on the advisory board of; serving as consultants, advisors, or speakers for; or receiving honoraria or grants from Pfizer or others. Seven authors declared being current or former employees and shareholders of Pfizer.
