Mpox Pharyngitis.

A case of mpox pharyngitis in absence of cutaneous lesions is reported. Usually, clinical presentation is either a cutaneous eruption or a combination of cutaneous and mucosal lesions. In patients with atypical pharyngitis, regardless of the presence of skin lesions, pharyngeal swabs should be collected to rule out mpox.

Scalp Melanoma: A High-Risk Subset of Cutaneous Head and Neck Melanomas with Distinctive Clinicopathological Features.

Scalp melanomas (SM) have been previously associated with poor overall and melanoma-specific survival rates. The aim of this study was to describe and compare the clinicopathological characteristics and survival outcomes of SM and non-scalp cutaneous head and neck melanoma (CHNM). An observational multi-center retrospective study was designed based on patients with CHNM followed in two tertiary care hospitals. A hundred and fifty-two patients had CHNM, of which 35 (23%) had SM. In comparison with non-scalp CHNM, SM were more frequently superficial spreading and nodular subtypes, had a thicker Breslow index median (2.1 mm vs. 0.85 mm), and a higher tumor mitotic rate (3 vs. 1 mitosis/mm2) (p < 0.05). SM had a higher risk of recurrence and a higher risk of melanoma-specific death (p < 0.05). In the multivariate analysis, scalp location was the only prognostic factor for recurrence, and tumor mitotic rate was the only prognostic factor for melanoma-specific survival. We encourage routinely examining the scalp in all patients, especially those with chronic sun damage.

Clinicopathological characteristics of cutaneous and mucocutaneous leishmaniasis in patients treated with TNF-α inhibitors.

BACKGROUND AND OBJECTIVES: The increasing use of biologics in the treatment of inflammatory diseases has led to more cases of leishmaniasis in patients subjected to iatrogenic immunosuppression. The main objective was to describe the characteristics of the patients with cutaneous (CL) or mucocutaneous (MCL) leishmaniasis who were receiving a biological therapy at the time of diagnosis. PATIENTS AND METHODS: A multicenter retrospective study was design based on a cohort of patients diagnosed with CL or MCL. All patients who were being treated with biologicals were included. For each case, two matched non-exposed patients were included for comparison. RESULTS: 38 patients were diagnosed with CL or MCL while being treated with tumor necrosis factor alpha (TNF-α) inhibitors. Leishmaniasis presented more frequently as a plaque (58.3%) with a larger median lesion size (2.5 cm), ulceration (92.1%), and required a greater median number of intralesional meglumine antimoniate infiltrations (3 doses) (P < 0.05) than in non-exposed patients. We found no systemic involvement in patients being treated with anti-TNF-α. We did not find differences regarding the treatment characteristics whether biologic therapy was modified or not. CONCLUSIONS: Although management should be individualized, maintenance of biologic therapy does not seem to interfere with treatment of CL or MCL.

Multiple Primary Melanomas: Retrospective Review in a Tertiary Care Hospital.

Multiple primary melanomas (MPM) refer to the occurrence of more than one synchronous or metachronous melanoma in the same individual. The aim of this study was to identify the frequency of MPM and describe the clinical and histopathologic characteristics of patients with MPM. An observational single-center retrospective study was designed based on a cohort of melanoma patients followed in a tertiary care hospital. Fifty-eight (8.9%) patients developed MPM. Most patients were men (65.5%) and the median age at the time of diagnosis of the first melanoma was 71 years old. The median time of diagnosis of the second melanoma from the first melanoma was 10.9 months, and 77.6% of second melanomas were diagnosed within the first 5 years. In total, 29 (50%) and 28 (48.3%) first and second melanomas were located in the trunk, respectively. Concordance of anatomic site between primary and subsequent melanoma was found in 46.6% of the patients. Proportion of in situ melanomas was increasingly higher in subsequent melanomas (from 36.21% of first melanomas to 100% of fifth melanomas). An increasing rate of melanomas with histological regression was observed within subsequent melanomas (from 60.3% of first melanomas to 80% of third melanomas). Our results support the importance of careful long-term follow-up with total body examination in melanoma patients.

Multiple pilomatricomas in a child with xeroderma pigmentosum: Coincidence or association?

The association of multiple pilomatricomas with xeroderma pigmentosum has not been described. We report a case of a child with multiple pilomatricomas and photosensitivity who was found to have a pathogenic variant in exon 4 of XPA and a likely pathogenic variant in COL6A1.

Injuria renal aguda: Características clínicas y epidemiológicas y función renal al alta en un hospital en Perú / Acute kidney injury: Clinical and epidemiological features and kidney function at discharge in a hospital in Peru

Objetivo: Describir las características de la Injuria Renal Aguda (IRA) en pacientes hospitalizados en un hospital de tercer nivel de enero a abril del 2016. Material y métodos: Estudio descriptivo, transversal y retrospectivo que incluyó a los pacientes que ingresaron a los servicios de hospitalización de Medicina y Unidad de Cuidados Intensivos. El diagnóstico de IRA y su clasificación según severidad fueron establecidos según los criterios propuestos por Kidney Disease: Improving Global Outcomes. La función renal al alta fue evaluada mediante la estimación de la tasa de filtración glomerular (TFG). Resultados: La frecuencia general de IRA fue 64,83%. En el servicio de Medicina, la frecuencia fue 57,06% y en UCI, 88,14%. La mortalidad general fue 27,45%. Los pacientes con IRA presentaron anemia, diabetes y enfermedad renal crónica en 84,97%, 20,92% y 19,61%, respectivamente. Según severidad, la frecuencia general fue estadio 3: 46,41%, estadio 1: 30,07% y estadio 2: 23,53%. Las categorías de etiología probable más frecuentes fueron intrínseca (41,83%), pre-renal (27,45%) y multifactorial (15,03%). La mediana de TFG al alta en los pacientes que estuvieron en UCI fue 114,40 ml/min/1,73 m2 y en Medicina, 84,89 ml/min/1,73 m2. Según severidad, la menor mediana de TFG al alta se presentó en los pacientes con estadio 3 y, según etiología probable, aquellos que desarrollaron IRA intrínseca y multifactorial presentaron menor función renal al alta. Conclusiones: IRA es un trastorno frecuente en pacientes hospitalizados. La TFG al alta fue significativamente mayor en los pacientes en UCI que en aquellos en Medicina.

Objetive: To describe the characteristics of Acute Kidney Injury (AKI) in hospitalized patients in a tertiarylevel hospital from January to April of 2016. Material and methods: Retrospective descriptive study that included patients admitted to medical ward and Intensive Care Unit. AKI diagnosis and severity stage were established according to Kidney Disease: Improving Global Outcomes criteria. Kidney function at discharge was evaluated by estimating the glomerular filtration rate (GFR). Results: Overall frequency of AKI was 64.83%. In the medical ward, frequency was 57.06% and in ICU, 88.14%. Overall mortality was 27.45%. The proportion of patients with AKI who had anemia, diabetes and chronic kidney disease was 84.97%, 20.92% and 19.61%, respectively. According to severity stage, the overall frequency was stage 3: 46.41%, stage 1: 30.07% and stage 2: 23.53%. The most frequent categories of probable etiology were intrinsic (41.83%), prerenal (27.45%) and multifactorial (15.03%). The GFR median at discharge in ICU was 114.40 ml/min/1.73 m2, whereas in medical ward, 84.89 ml/min/1.73 m2. According to the severity stage, the lowest GFR median at discharge occurred in patients with stage 3 and, according to probable etiology, those who developed intrinsic and multifactorial AKI had lower kidney function at discharge. Conclusions: AKI is a frequent disorder in hospitalized patients. The GFR at discharge was significantly higher in patients who were in ICU than in medical ward.
