Perceptions of telehealth among inpatient consultative dermatology providers and practice patterns during COVID-19.

Use of inpatient teledermatology increased during the COVID-19 pandemic. We surveyed the Society for Dermatology Hospitalists to better characterize the impact of COVID-19 on teledermatology use by inpatient dermatology providers, particularly on provider perceptions of teledermatology. Prior to the COVID-19 pandemic, 40% (8/20) of surveyed providers had used telehealth at their institution to help perform inpatient consults, while 90% (18/20) adapted use of teledermatology during the pandemic. 80% (16/20) reported that their opinion of teledermatology changed as a result of the COVID-19 pandemic, with the vast majority (87.5%, 14/16) reporting having a more positive opinion. Benefits of teledermatology included efficiency, ability to increase access safely, and ability for clinicians to focus on complex cases. Some providers expressed concerns over the potential implications regarding the perception of dermatology within medicine, limitations of inadequate photos, and breakdowns in communication with consulting teams and patients. Robust algorithms and or utilization criteria of teledermatology may help to mitigate risk, while increasing access to inpatient dermatologic evaluation.

Mycobacterium mucogenicum skin and soft tissue infection of the breast mimicking idiopathic granulomatous mastitis.

We present a case of a 28-year-old woman who came to medical attention after noticing a breast mass associated with an overlying eroded plaque of the skin. A core biopsy of the breast mass was negative for malignancy but demonstrated granulomatous inflammatory changes. Acid-fast bacilli and Gomori methenamine-silver stains were negative for microorganisms. The patient was diagnosed with presumptive idiopathic granulomatous mastitis and started on oral steroids. Her symptoms progressed. Tissue culture from a repeat biopsy grew Mycobacterium mucogenicum The patient responded well to combination oral antimicrobial therapy.

Vulvar Majocchi granuloma and kerion formation in an immunocompetent female.

We report a rare case of vulvar Majocchi granuloma and kerion formation secondary to Trichophyton in an immunocompetent woman. The patient responded well to oral terbinafine and a short course of oral corticosteroids with a slow taper. Resolution of deep dermatophytosis requires prompt pathogen identification and treatment to avoid scarring and hair loss. Herein, we aim to increase clinical awareness and early recognition of this atypical presentation of a Majocchi granuloma with kerion formation.

Cutaneous Involvement in a Case of Intravascular T-Cell Lymphoma With a γδ Phenotype.

Intravascular lymphomas (IVL) are uncommon variants of extranodal non-Hodgkin which are usually difficult to diagnose because of their lack of clinical uniformity. Most cases are of B-cell differentiation followed by natural killer/T-cell differentiation and underlying CD30 lymphoproliferative conditions. Epstein-Barr virus is pathogenically related in most of the natural killer/T-cell variants, and the skin is a common site of presentation noted in approximately 40% of cases. Recently, cases with uncommon phenotypes have been described, expanding our understanding of the pathogenesis of this condition. In this report, we describe a 67-year-old man with a 3-month history of constitutional symptoms associated with linear purpuric macules on the trunk, pancytopenia, and high levels of serum lactate dehydrogenase. He had been followed for longstanding adenopathy and hepatosplenomegaly. Skin biopsy demonstrated a intravascular lymphocytic proliferation with positivity for CD3, CD2, CD5, and γδ T-cell receptor marker; in situ hybridization Epstein-Barr virus RNA was negative. The patient was subsequently treated with chemotherapy and allogenic stem cell transplant. He remains in complete remission 6 months posttransplant. Although the presence of hepatosplenomegaly led to consideration of a hepatosplenic T-cell lymphoma, it was pre-existing for several years making the diagnosis doubtful. To our knowledge, this is the first case report of an IVL γδ T-cell lymphoma.

Decreased respiratory quotient in relation to resting energy expenditure in HIV-infected and noninfected subjects.

The purpose of this study was to evaluate the relationship of respiratory quotient (RQ), a surrogate marker of substrate oxidation, as well as body composition and dietary intake to resting energy expenditure (REE) among HIV-infected patients in the current era of highly active antiretroviral therapy and among non-HIV-infected control subjects. Resting energy expenditure is increased in HIV-infected patients; but little is known regarding the potential contribution of altered substrate metabolism, body composition, and dietary intake to increased energy expenditure in this population. Respiratory quotient, REE, body composition, and dietary intake parameters were assessed in 283 HIV-infected patients and 146 community-derived HIV-negative controls who were evaluated for metabolic studies between 1998 and 2005. Respiratory quotient was lower (0.83 +/- 0.00 vs 0.85 +/- 0.01, P = .005), whereas REE adjusted for fat-free mass (FFM) was higher (31.8 +/- 0.3 vs 29.8 +/- 0.3 kcal/[d kg], P < or = .0001), in HIV-infected compared with control subjects. In multivariate modeling among HIV-infected patients, including age, sex, and parameters of immune function, FFM (beta = 24.811334, P < .0001), visceral adiposity (beta = .7182746, P = .008), and total body fat (beta = 8.0506839, P = .041) were positively associated with REE, whereas RQ was negatively associated with REE (beta = -528.4808, P = .024). Overall r(2) was equal to 0.705 and P was less than .0001 for the model. In control subjects, by contrast, only visceral adiposity (beta = 1.0612073, P = .004), total body fat (beta = 15.805547, P = .010), and FFM (beta = 22.613005, P < .0001) were significant predictors of REE; and there was no relationship with RQ. Overall r(2) was equal to 0.825 and P was less than .0001 for the model. These data suggest that alterations in substrate metabolism may contribute to increased REE in HIV-infected patients compared with control subjects.
