High prevalence of syphilis among recyclable waste collectors in Central Brazil.

BACKGROUND: Syphilis is associated with social and behavioral factors. METHODS: This cross-sectional study determined the prevalence of syphilis and its associated risk factors among recyclable waste collectors in Central Brazil. RESULTS: A lifetime syphilis prevalence rate of 7.91% (95% confidence interval: 5.25-11.75) was found among 278 participants. Low educational level, history of sexually transmitted infection, and age ≥ 36 years were associated with a high prevalence of lifetime syphilis. CONCLUSIONS: These findings emphasize the need for syphilis prevention, screening, and treatment among recyclable waste collectors, highlighting the potential for the spread of infection in vulnerable populations.

A Rare Case of Aspergillus Mediastinitis After Coronary Artery Bypass Surgery: A Case Report and Literature Review.

BACKGROUND Mediastinitis is a serious complication after cardiac surgery; it is a deep sternal wound infection following sternotomy, with clinical evidence and/or microbiological involvement and sternal osteomyelitis. The most common pathogens are Staphylococcus spp (S. aureus), followed by gram-negative organisms. Establishing an etiological diagnosis of fungal mediastinitis is often a challenging issue, given the nonspecific clinical presentation. CASE REPORT A 74-year-old man was diagnosed with a three-vessel coronary artery disease in a university hospital. The patient had as clinical background hypertension, a body mass index (BMI) of 29.78 kg/m², and no diabetes mellitus. After an uneventful coronary artery bypass surgery, he presented clinical and radiological mediastinitis manifestations on the 9th postoperative day. He was treated with a range of antibiotics, with no clinical improvement until the 33rd postoperative day. Then, mediastinal fluid and biopsied tissue were collected and he was started on voriconazole due to growing Aspergillus spp. On the 93rd postoperative day, he had clinical improvement and, after several exams, was released from the hospital. We present the first report of Aspergillus fumigatus mediastinitis after cardiac surgery in Brazil, successfully treated with voriconazole. CONCLUSIONS Aspergillus infection should be considered in the differential diagnosis of mediastinitis after coronary surgery, especially in a clinical case of unexplained sepsis, negative blood culture, and no clinical improvement despite antibiotic therapy. This case report highlights that the mediastinal fluid and biopsy tissue culture can be useful for the diagnosis of fungal mediastinitis.

High level of exposure to hepatitis B virus infection in a vulnerable population of a low endemic area: A challenge for vaccination coverage.

OBJECTIVES: To evaluate the epidemiological and molecular features of HBV infection among recyclable waste collectors. METHODS: The participants were recruited from the dumping ground and recycling cooperatives in Campo Grande, Brazil, and were screened for hepatitis B and C, and HIV serological markers by ELISA, confirmed by PCR. RESULTS: Among 278 participants, 63.7% (95% CI: 58.0-69.3) were considered susceptible to HBV infection. The prevalence rate of HBV exposure was 10.1% (95% CI: 6.5-13.6) and 0.4% (95% CI: 0.1-0.6) were chronic carriers. Age ≥45 years (AOR=7.15), history of homosexual contact (AOR=5.29), tattoo (AOR=4.92) and history of surgery (AOR=2.89) were factors associated with ever infection. Age 18-25 years (AOR=4.63), educational level ≥9 years (AOR=1.98) and knowledge about HBV transmission (AOR=3.08) were associated with serological HBV vaccination like profile (26.2%; 95% CI: 21.1-31.4). CONCLUSIONS: Despite the availability and efficacy of HBV vaccine, this study found high HBV exposure and proportion of susceptible adults in a low endemic area. Vaccination and screening campaigns using accessible language to the economically disadvantaged populations can reduce the number of people susceptible to HBV infection.

Enteroparasites in Riverside Settlements in the Pantanal Wetlands Ecosystem.

BACKGROUND: Intestinal parasites are a major source of health problems in developing countries, where socioeconomic, cultural, and environmental conditions contribute in maintaining the biological cycles of various parasites and facilitating their spread. The objective of this study, conducted in Corumbá, Mato Grosso do Sul state, Brazil, was to investigate the occurrence of intestinal parasites in riverside communities in the South Pantanal wetlands and conduct educational interventions focused on health and environmental preservation. METHOD: In total, 196 stool samples were tested for parasites using the merthiolate-iodine-formaldehyde concentration (MIFC) technique and spontaneous sedimentation and educational activities were carried out. RESULTS: Enteroparasite prevalence was 72% (65.6-78.2%; 95% CI). Of the 141 positive cases, monoparasitism was found in 34.7%, biparasitism in 23%, and polyparasitism in 14.3%. Entamoeba coli was the most frequent protozoan (70.2%). Among helminths, hookworms were the most prevalent. Enteroparasitosis prevalence did not differ for sex or place of abode but proved higher in individuals older than 10 years. CONCLUSION: The high positivity rate for enteroparasites found for the communities stems from lack of sanitation and poor personal and environmental hygiene habits, indicating that effective health policies and educational interventions are needed to reduce the current risk levels.

Leishmania infantum AS A CAUSATIVE AGENT OF CUTANEOUS LEISHMANIASIS IN THE STATE OF MATO GROSSO DO SUL, BRAZIL.

Cutaneous leishmaniasis is caused by different species of the Leishmania genus. Leishmania(Leishmania) infantum, causing cutaneous leishmaniasis, has been described in patients living in areas where visceral leishmaniasis is endemic. In this study, it was possible to characterize this species in seven slides from cutaneous tissue imprints from patients with cutaneous leishmaniasis in the State of Mato Grosso do Sul, Brazil.

Disseminated cutaneous atypical mycobacteriosis by M. chelonae after sclerotherapy of varicose veins in a immunocompetent patient: a case report.

Atypical mycobacteria are saprophytic organisms not transmitted from person to person, which affect mainly immunosuppressed but also immunocompetent individuals. We present a case of atypical mycobacteriosis after a vascular procedure, with widespread cutaneous lesions associated with polyarthralgia. Mycobacterium chelonae was identified by the polymerase chain reaction (PCR) method. The patient showed improvement after treatment with three antibiotics. Mycobacterium chelonae causes skin lesions after invasive procedures. The clinical form depends on the immune state of the host and on the entry points. The diagnosis is based essentially on culture and the mycobacteria is identified by PCR. We highlight the importance of investigating atypical mycobacteriosis when faced with granulomatous lesions associated with a history of invasive procedures.

Treinamento do assoalho pélvico na retenção urinária decorrente de encefalomielite aguda disseminada / Pelvic floor muscle training in neurogenic bladder due to acute disseminated encephalomyelitis syndrome

A dengue pode desencadear manifestações neurológicas como a Síndrome de Encefalomielite Aguda Disseminada (ADEM), de caráter inflamatório, desmielinizante, que pode ter dentre as consequências déficits motores e sensitivos, neurite ótica e disfunções vesicais, como a retenção urinária, tornando o indivíduo dependente da realização do cateterismo vesical intermitente (CVI). Desta forma, o objetivo deste estudo é descrever o tratamento fisioterapêutico de uma paciente com retenção urinária, decorrente de Síndrome de ADEM pós-dengue. Paciente do sexo feminino, 52 anos, internada em hospital de média complexidade com diagnóstico de ADEM. Na avaliação inicial apresentava grau de força muscular 3 de membros inferiores e 4 de membros superiores, 2 de musculatura do assoalho pélvico (MAP) e retenção urinária, necessitando realizar CVI. Foram realizados 32 atendimentos com duração de uma hora, incluindo o treinamento do assoalho pélvico em diferentes posturas e eletroestimulação de superfície da MAP com equipamento da marca Ibramed. Paciente recebeu alta hospitalar com evidente melhora da força muscular global e sem necessidade de CVI, apresentando micção voluntária e sem resíduo pós-miccional, favorecendo a prevenção de agravos do trato urinário inferior e superior.

Dengue can trigger neurological manifestations such as Acute Disseminated Encephalomyelitis (ADEM), with inflammatory, demyelinating condition, which may have, among the consequences, motor and sensory deficits, optic neuritis and bladder dysfunctions, such as urinary retention, making the individual dependent on intermittent bladder catheterization (IBC). Therefore, the objective of this study was to describe the physiotherapeutic treatment of a patient with urinary retention, due to ADEM syndrome after dengue. A 52-year-old female patient admitted to a hospital of medium complexity with a diagnosis of ADEM. In the initial evaluation, she presented a degree 3 of muscular strength in the lower limbs and 4 in the upper limbs, 2 in pelvic floor musculature (PFM) and urinary retention, requiring IBC. We performed 32 one hour sessions, including pelvic floor muscle training in different positions and surface electrostimulation of PFM with Ibramed brand equipment. Patient was discharged with evident improvement of global muscle strength and without IBC, presenting voluntary voiding and without post void residual, favoring the prevention of lower and upper urinary tract injuries.
