Severe esophagitis induced by antituberculosis drugs: a case report.

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.

Oral manifestations of COVID-19 in unvaccinated patients: a cross-sectional study.

BACKGROUND: Early studies have highlighted the possible development of dysgeusia and anosmia in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and these manifestations should be considered a potential indication of coronavirus disease 19 (COVID-19). As potential contributors to these symptoms, dentists should perform careful oral and oropharyngeal examinations and document suspicious oral lesions in patients with COVID-19, especially in those who complain of loss of taste and smell. The study's objective was to assess the prevalence of oral manifestations among ambulatory unvaccinated symptomatic patients with suspected COVID-19 during the acute phase of the disease. METHODS: This cross-sectional study evaluated oral manifestations in adults (aged ≥ 18 years) with suspected and confirmed SARS-CoV-2 infection. Chi-square and Fisher's exact tests were used to compare data between the groups (rRT-PCR-positive and rRT-PCR-negative patients). RESULTS: One hundred thirty-six participants were included. Most were female (n = 79; 58.1%), with a mean age of 39.53 (± 14.17) years. Of these, 54 (39.7%) had a positive rRT-PCR test, and 82 (60.3%) had negative rRT-PCR results. Oral manifestations were observed in 40 participants (74.1%) in the rRT-PCR-positive group and 67 participants (81.7%) in the rRT-PCR-negative group. The most common oral manifestations were xerostomia (n = 85; 62.5%) and dysgeusia/ageusia (n = 57; 41.9%). Different rates of gingivitis (n = 12; 22.2% vs. n = 5; 6.1%; p = 0.005) and halitosis (n = 7; 13.0% vs. n = 1; 1.2%; p = 0.007) were observed between the rRT-PCR-positive and -negative groups, respectively. Mouth ulcers, glossitis, tongue coating, and petechiae were reported in both groups without significant differences. CONCLUSIONS: A high prevalence of oral manifestations was observed in symptomatic patients with suspected or confirmed COVID-19. CLINICAL RELEVANCE: This study highlights the importance of routine oral examinations by dentists as part of the multidisciplinary care of COVID-19 patients.

Acute pulmonary histoplasmosis: a case series from an outbreak in Southeastern Brazil.

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.

Severe form of lymphocutaneous sporotrichosis: a case report.

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.

Fatal Brazilian spotted fever in a healthy military man during field training in Rio de Janeiro city, southeastern Brazil.

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.

Investigation of SARS-CoV-2 infection in dogs and cats of humans diagnosed with COVID-19 in Rio de Janeiro, Brazil.

BACKGROUND: Infection by SARS-CoV-2 in domestic animals has been related to close contact with humans diagnosed with COVID-19. Objectives: To assess the exposure, infection, and persistence by SARS-CoV-2 of dogs and cats living in the same households of humans that tested positive for SARS-CoV-2, and to investigate clinical and laboratory alterations associated with animal infection. METHODS: Animals living with COVID-19 patients were longitudinally followed and had nasopharyngeal/oropharyngeal and rectal swabs collected and tested for SARS-CoV-2. Additionally, blood samples were collected for laboratory analysis, and plaque reduction neutralization test (PRNT90) to investigate specific SARS-CoV-2 antibodies. RESULTS: Between May and October 2020, 39 pets (29 dogs and 10 cats) of 21 patients were investigated. Nine dogs (31%) and four cats (40%) from 10 (47.6%) households were infected with or seropositive for SARS-CoV-2. Animals tested positive from 11 to 51 days after the human index COVID-19 case onset of symptoms. Three dogs tested positive twice within 14, 30, and 31 days apart. SARS-CoV-2 neutralizing antibodies were detected in one dog (3.4%) and two cats (20%). In this study, six out of thirteen animals either infected with or seropositive for SARS-CoV-2 have developed mild but reversible signs of the disease. Using logistic regression analysis, neutering, and sharing bed with the ill owner were associated with pet infection. CONCLUSIONS: The presence and persistence of SARS-CoV-2 infection have been identified in dogs and cats from households with human COVID-19 cases in Rio de Janeiro, Brazil. People with COVID-19 should avoid close contact with their pets during the time of their illness.

Treatment of cutaneous sporotrichosis with itraconazole--study of 645 patients.

BACKGROUND: Itraconazole has become the first choice for treatment of cutaneous sporotrichosis. However, this recommendation is based on case reports and small series. The safety and efficacy of itraconazole were evaluated in 645 patients who received a diagnosis on the basis of isolation of Sporothrix schenckii in Rio de Janeiro, Brazil. METHODS: A standard regimen of itraconazole (100 mg/day orally) was used. Clinical and laboratory adverse events were assessed a grades 1-4. A multivariate Cox model was used to analyze the response to treatment. RESULTS: The median age was 43 years. Lymphocutaneous form occurred in 68.1% and fixed form in 23.1%. Six hundred ten patients (94.6%) were cured with itraconazole (50-400 mg/day): 547 with 100 mg/day, 59 with 200-400 mg/day, and 4 children with 50 mg/day. Three patients switched to potassium iodide, 2 to terbinafine, and 4 to thermotherapy. Twenty-six were lost to follow-up. Clinical adverse events occurred in 18.1% of patients using 100 mg/day and 21.9% of those using 200-400 mg/day. The most frequent clinical adverse events were nausea and epigastric pain. Laboratory adverse events occurred in 24.1%; the most common was hypercholesterolemia, followed by hypertriglyceridemia. Four hundred sixty-two patients (71.6%) completed clinical follow-up, and all remained cured. Only 2 variables were significant in explaining the cure: patients with erythema nodosum healed faster, and lymphocutaneous form took longer to cure. CONCLUSIONS: In the current series, the therapeutic response was excellent with the minimum dose of itraconazole, and there was a low incidence of adverse events and treatment failure.

Trends in a Cohort of HIV-infected pregnant women in Rio de Janeiro, 1996-2004

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 percent, stillbirths 2.5 percent, miscarriages 0.6 percent, neonatal mortality 1.1 percent, prematurity 9.9 percent, low birth weight (LBW) 16.5 percent, congenital malformations 2.2 percent. 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 percent in P1 to 45 percent in P3. The proportion of pregnant women receiving highly active antiretroviral therapy increased from none (P1) to 88 percent (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 percent in P1 to 48 percent in P3. Perinatal transmission rates were 2.4 percent with a decline from 3.5 percent in P1 to 1.6 percent 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.

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 por cento, natimortos 2,5 por cento, abortos 0,6 por cento, mortalidade neonatal 1,1 por cento, prematuridade 9,9 por cento, baixo peso ao nascer (BPN) 16,5 por cento, malformações congênitas 2,2 por cento. 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 por cento em P1 para 45 por cento em P3. A proporção de gestantes recebendo o tratamento combinado potente aumentou de zero em P1 para 88 por cento 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 por cento em P1 para 48 por cento em P3. A taxa de transmissão perinatal global foi de 2,4 por cento caindo de 3,5 por cento em P1 para 1,6 por cento 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...

Perfil epidemiológico, clínico e terapêutico da esporotricose no Instituto de Pesquisa Clínica Evandro Chagas- FIOCRUZ, Rio de Janeiro, no período de 2002 a 2004 / The epidemiological, clinical and therapeutic profile of the sporotrichosis in the Instituto de Pesquisa Clínica Evandro Chagas- FIOCRUZ, Rio de Janeiro from 2002 through 2004

A esporotricose assumiu, a partir de 1998, uma importância sem precedentes no estado do Rio de Janeiro onde atingiu proporções epidêmicas. A casuística apresentada neste manuscrito é a maior já documentada no país e a maior epidemia da doença por transmissão zoonótica do mundo. O presente estudo relata as características epidemiológicas, clínicas e terapêuticas de 572 casos de esporotricose humana com diagnostico laboratorial confirmado pelo isolamento de Sporothrix schenckii em cultura. Todos os pacientes foram atendidos no ambulatório de esporotricose do Instituto de Pesquisas Evandro Chagas (Fundação Oswaldo Cruz – Rio de Janeiro) no período de 2002 a 2004. A infecção esteve relacionada à transmissão por gatos domésticos, que também desenvolveram a doença. A forma clínica mais freqüente foi a cutâneo-linfática, seguida das formas cutânea localizada e cutânea disseminada. A doença foi mais freqüente em adultos do sexo feminino. O itraconazol na dose de 100mg, em dose única diária foi eficiente na maioria dos casos tratados (96,5por cento), por um período médio de 12 semanas, sem reações adversas graves.
