RESUMO
BACKGROUND: Sporotrichosis is a fungal implantation disease of subacute/ chronic course caused by species of the dimorphic fungus Sporothrix spp. This infection usually develops after traumatic inoculation of contaminated soil, plants or organic material contaminated by Sporothrix spp. conidia into skin or mucosa. The objective of this work is to contribute to the knowledge of sporotrichosis in Uruguay by providing a report of a series of cases diagnosed in a reference center. METHODS: We conducted a retrospective, observational, descriptive and cross-sectional study of cases of sporotrichosis diagnosed in the last 38 years. RESULTS: In the period analyzed, 157 cases of sporotrichosis were diagnosed, 152 of those corresponded to male patients. The most frequent clinical presentation was nodular lymphatic in 120 patients. In relation to epidemiological antecedents, 128 patients had been scratched by armadillos during hunting. CONCLUSIONS: Sporotrichosis in Uruguay is a sporadic disease with a clear seasonal pattern related to particular social practices, such as hunting armadillos. Related to this practice, the affectation is greater in males and in young adults.
RESUMO
The role of circumcision in partially protecting against sexually transmitted infections (STIs) and other dermatoses has been documented. Neonatal circumcision is not routinely practiced in South America. Although it is logical to assume that male genital dermatoses are more prevalent in Hispanic men, they are underrepresented in the existing literature. Objective: To describe the epidemiological characteristics from our male genital dermatology unit in Montevideo (Uruguay), the diagnoses, and correlate them with circumcision status and comorbidities. Methods: A retrospective observational cohort study was conducted. A dermatologist and urologist evaluated all patients using standard questionnaires. In 3 years and 8 months, 269 patients were seen. Median age was 41, prevalence of neonatal circumcision was 0.7%, HIV was 4.2%, STIs were 24.9%, non-STIs were 63.9%, and both (STI + non-STI) were 11.2%. Most frequent entities: eczema/balanoposthitis (27.1%), condyloma (24.9%), and lichen sclerosus (15.6%). Data correlating circumcision and other diagnoses did not reach statistical significance. HIV was positively associated with other STIs (p < 0.05), and an association with balanoposthitis was seen; however, it did not reach statistical significance (p < 0.1). Main limitation was small sample size. This is the first study of its kind based on Hispanic patients. Collaboration between specialties proved to be fundamental. Further studies are needed in this demographic to find an association between circumcision, comorbidities, and genital dermatoses.

Introducción: La histoplasmosis es una micosis sistémica que afecta a humanos, su agente Histoplasma capsulatum, hongo dimorfo, es ubicuo en la naturaleza. Frecuentemente se presenta como reactivación en personas con infección por VIH/SIDA, con manifestaciones polimórficas y diseminadas. Las lesiones mucocutáneas son una importante llave diagnóstica. Objetivo: Contribuir al conocimiento de esta patología a través del reporte de los diagnósticos de laboratorio de histoplasmosis realizados en Uruguay en los últimos 10 años. Materiales y Métodos: Se realizó un estudio observacional, retrospectivo de las histoplasmosis diagnosticadas en el laboratorio de referencia de Micología de Facultad de Medicina y dos laboratorios clínicos. Se enrolaron los registros clínicos y analíticos asociados. Resultados: Fueron 69 los diagnósticos de histoplasmosis. Más de 80% correspondió a personas con infección por VIH/SIDA. El 62,3% del total presentó lesiones de piel y/o mucosas y en 58% el diagnóstico se realizó mediante el estudio de estas. El 62,3% de los diagnósticos se realizaron mediante la visualización al microscopio óptico de frotis coloreados. Conclusiones: La mayoría de las histoplasmosis se vinculan a la infección por VIH/SIDA. El estudio micológico de las lesiones de piel y/o de mucosas, es accesible, mínimamente invasivo, rápido y presenta una excelente performance diagnóstica.
Background: Histoplasmosis is a systemic mycosis that affects humans, its agent Histoplasma capsulatum, a dimorphic fungus, is ubiquitous in nature. It frequently presents as reactivation in people with HIV/AIDS infection, with polymorphic and disseminated manifestations. Mucocutaneous lesions are characteristic and an important diagnostic key. Aim: To contribute to the knowledge of this pathology through the report of histoplasmosis laboratory diagnosis made in Uruguay in the last 10 years. Methods: We conducted an observational, retrospective study of diagnosed histoplasmosis in the Mycology reference laboratory of the Faculty of Medicine and two clinical laboratories. Associated clinical and analytical records were obtained. Results: There were 69 histoplasmosis diagnoses. More than 80% corresponded to people with HIV/AIDS infection. 62.3% of the total presented skin and/or mucosal lesions and in 58% the diagnosis was made by studying them. 62.3% of the diagnoses were initially made by viewing colored smears under an optical microscope. Conclusions: Most histoplasmosis is linked to HIV/AIDS infection. Exposure to a high fungal load is a constant in cases of immunocompetent individuals. The mycological study of skin and/or mucosal lesions is accessible, minimally invasive, fast and has excellent diagnostic performance.
