ABSTRACT Tuberculosis stands as one of humanity’s oldest afflictions, intrinsically intertwined with social disparities. This formidable disease spares no age group and remains the prevailing cause of infection-induced mortality worldwide, particularly in developing nations. We present a case of a 56-year-old woman with diabetes who was diagnosed with Pulmonary Tuberculosis. After receiving antituberculosis drugs as part of her treatment, she experienced a range of systemic manifestations and suffered from severe ulcerative esophagitis. This adverse reaction led to uncontrollable gastrointestinal intolerance, tragically resulting in her untimely demise. The incident underscores the potential seriousness of adverse reactions that can arise from tuberculosis treatment medications. humanitys humanity s afflictions disparities infectioninduced infection induced worldwide nations 56yearold yearold 56 year old esophagitis intolerance demise medications 5

ABSTRACT Paracoccidioidomycosis, the most important systemic mycosis in Latin America, is closely linked to rural activities. In Brazil, it is an endemic disease, with an estimated 4,000 to 6,000 annual cases, accounting for over 80% of the global diagnoses. We present an intriguing case of this disease with an intestinal manifestation in a 71-year-old woman. The involvement of the cecal appendix led to a complication of cholangitis that mimicked cholangiocarcinoma.

ABSTRACT Histoplasmosis is a systemic mycosis prevalent in the Americas. Humans become infected via the respiratory route by inhaling aerosols from soil contaminated with bird and bat excretions. Acute pulmonary histoplasmosis is usually asymptomatic and is more often a self-limiting illness. We report a series of seven acute pulmonary cases in adults during an outbreak in Nova Friburgo city, Rio de Janeiro State, Brazil, in a group of volunteers who were cleaning an old, abandoned house without using personal protective equipment. The patients had a favorable evolution after suitable treatment, but all required hospitalization.

ABSTRACT Sporotrichosis is the most frequent subcutaneous mycosis in Latin America. It is caused by species of the genus Sporothrix. Infection in humans occurs through the entry of the fungus into the skin. Zoonotic outbreaks involving cats in the transmission of the disease have been frequently reported. The lymphocutaneous form is the most commonly observed and the upper limbs are the most affected sites. We report a case of a 64-year-old healthy female patient with a lymphocutaneous form with rapid progression of lesions, which was refractory to initial treatment with itraconazole. Treatment with liposomal amphotericin B was performed with a satisfactory resolution, but aesthetic and functional sequelae in the left upper limb were installed. America Sporothrix skin reported sites 64yearold yearold 64 year old lesions itraconazole resolution installed 6

ABSTRACT Brazilian spotted fever, a zoonotic disease transmitted by ticks, is caused by Rickettsia rickettsii. We report a fulminant case of this zoonosis in a healthy 46-year-old military man in the urban region of Rio de Janeiro city, in October, 2021. Ticks and capybaras (Amblyomma sculptum, Hydrochoerus hydrochaeris, respectively) were identified in the military fields, pointing to the participation of this large synanthropic rodent, recognized as an efficient amplifier host of Rickettsia rickettsii in Brazil. As the military population is considered a risk group for spotted fever, it is necessary to alert health professionals to the importance of the early detection of the disease and its adequate management, mainly in populations that are particularly at risk of exposure to ticks, in order to avoid fatal outcomes.

OBJETIVOS: Descrever as tendências temporais nas características sociodemográficas, imunológicas e virológicas e as das condutas utilizadas para reduzir o risco da transmissão mãe-filho do HIV. MÉTODOS: Estudo de coorte retrospectivo em uma instituição de saúde terciária no Rio de Janeiro de janeiro de 1996 a dezembro de 2004. A análise utilizou a estratificação em três períodos de tempo: 1996-1998 (P1), 1999-2001 (P2) e 2002-2004 (P3). RESULTADOS: Em 9 anos, 622 gestações foram acompanhadas. As complicações foram: mortalidade materna 0,3%, natimortos 2,5%, abortos 0,6%, mortalidade neonatal 1,1%, prematuridade 9,9%, baixo peso ao nascer (BPN) 16,5%, malformações congênitas 2,2%. O número de gestantes HIV positivo triplicou ao longo do tempo, refletindo o aumento da prevalência da doença e a melhor identificação das pacientes. O diagnóstico da infecção pelo HIV antes da gestação aumentou de 30% em P1 para 45% em P3. A proporção de gestantes recebendo o tratamento combinado potente aumentou de zero em P1 para 88% em P3 com uma tendência significativa a ter uma carga viral abaixo do limite de detecção no parto nos últimos anos apesar de uma maior proporção de pacientes com doença mais avançada. O índice de cesarianas eletivas aumentou de 35% em P1 para 48% em P3. A taxa de transmissão perinatal global foi de 2,4% caindo de 3,5% em P1 para 1,6% em P3. Os desfechos neonatais tenderam a permanecer constantes ou a melhorar ao longo do tempo. Um discreto aumento dos índices de BPN e de malformações congênitas foi observado. CONCLUSÕES: Ao longo do período de estudo aumentou a proporção de gestantes HIV positivo com doença mais avançada e com padrão socioeconômico mais baixo. Por outro lado, a melhora da abordagem terapêutica dos pacientes infectados pelo HIV, associada a uma maior detecção de casos e maior acesso ao tratamento, resultou em uma redução da taxa de transmissão igualando-se à observada em países desenvolvidos com melhora concomitante de outros desfechos.

OBJECTIVE: To describe trends in sociodemographic, immunological and virological profiles and interventions to decrease the risk of mother-to-child HIV transmission. METHODS: Retrospective cohort study conducted at a tertiary institution in Rio de Janeiro, Brazil from January 1996 to December 2004. Analysis was performed by stratification in three time periods: 1996-1998 (P1), 1999-2001 (P2) and 2002-2004 (P3). RESULTS: In 9 years, 622 pregnancies occurred. Complications included: maternal mortality 0.3%, stillbirths 2.5%, miscarriages 0.6%, neonatal mortality 1.1%, prematurity 9.9%, low birth weight (LBW) 16.5%, congenital malformations 2.2%. The number of HIV-infected pregnant patients grew threefold over time reflecting increased prevalence of disease and patient identification. HIV diagnosis before pregnancy increased from 30% in P1 to 45% in P3. The proportion of pregnant women receiving highly active antiretroviral therapy increased from none (P1) to 88% (P3) with a significant trend towards women delivering at undetectable viral loads in later years despite a higher frequency of advanced disease. Scheduled cesarean deliveries increased from 35% in P1 to 48% in P3. Perinatal transmission rates were 2.4% with a decline from 3.5% in P1 to 1.6% in P3. Neonatal outcomes tended to remain constant or improve with time. A slight rise in LBW and congenital malformations were observed. CONCLUSIONS: During the observational period, HIV+ pregnant women presented with more advanced disease and lower socio-economic status. However, improved management of HIV-infected patients (associated with increased identification and increased availability of treatment) resulted into very low transmission rates similar to those of developed countries with overall improvement of patient outcomes.
