Paracoccidioidomicose: perfil clínico e epidemiológico de pacientes internados em Passo Fundo - RS / Paracoccidioidomycosis: clinical and epidemiological profile of patients hospitalized in Passo Fundo ­ RS

A paracoccidioidomicose não é uma doença de notificação obrigatória apesar de sua relevância na América Latina, por isso as estimativas de prevalência, incidência e morbidade dessa micose são baseadas em relatórios de levantamentos epidemiológicos, séries de casos, registros de hospitalização e dados de mortalidade. O objetivo desse trabalho foi descrever aspectos relacionados com o paciente, evolução da doença, confirmação diagnóstica e tratamento de casos confirmados de paracoccidioidomicose atendidos em um hospital de ensino do sul do Brasil. Foram coletadas informações de prontuários de 27 pacientes com diagnóstico de paracoccidioidomicose confirmado no período de 2010 até 2019. O perfil prevalente foi de um paciente do sexo masculino, com idade média de 53 anos, envolvido com atividades laborais diversas, de procedência urbana, imunocompetente e sem comorbidades, tabagista, mas não etilista. Para a maioria dos casos o acometimento inicial foi pulmonar, com importante envolvimento do sistema linfático no percurso da doença. A observação microscópica das estruturas fúngicas patognomônicas em amostras de biópsia, aspirado linfonodal e escarro foi o método mais utilizado para confirmar a suspeita clínica. O itraconazol foi a primeira opção de tratamento, seguido da anfotericina B. [au]

Paracoccidioidomycosis is not a notifiable disease despite its relevance in Latin America, so estimates of prevalence, incidence and morbidity of this mycosis are based on reports of epidemiological surveys, case series, hospitalization records and mortality data. The objective of this study was to describe aspects related to the patient, disease evolution, diagnostic confirmation and treatment of confirmed cases of paracoccidioidomycosis treated at a teaching hospital in southern Brazil. Information was collected from the medical records of 27 patients diagnosed with paracoccidioidomycosis confirmed in the period from 2010 to 2019. The prevalent profile was a male patient, with a mean age of 53 years, involved in various work activities, of urban origin, immunocompetent and without comorbidities, smoker, but non-alcoholic. For most cases, the initial involvement was pulmonary, with significant involvement of the lymphatic system in the course of the disease. Microscopic observation of pathognomonic fungal structures in biopsy samples, lymph node aspirate and sputum was the most used method to confirm the clinical suspicion. Itraconazole was the first treatment option, followed by amphotericin B. [au]

Mucinous cystic neoplasm of the liver

A 55-year-old woman was investigated for occasional epigastric pain and weight loss. T2-weighted abdominal magnetic resonance imaging and magnetic resonance cholangiography revealed a multilocular cyst with multiple septa and a solid component in the liver, measuring 6.1 × 4.8 × 6.5 cm. Given the patient's symptoms and malignant potential, a laparoscopic segmentectomy with partial resection of segments IV B and V was performed to completely remove the cystic lesion, associated with cholecystectomy. Histopathology demonstrated a cyst lined by columnar mucinous epithelium. Therefore, the diagnosis was mucinous cystic neoplasm of the liver. This article presents a case report and literature review of this entity.

Mesenteric desmoid tumor after Roux-en-Y gastric bypass: a case report

We report the case of a 37-year-old woman investigated for left flank pain 1 year after bariatric surgery (Roux-en-Y gastric bypass). Abdominal computed tomography (CT) revealed a solid intra-abdominal lesion measuring 9.3 × 9.4 × 10.4 cm, compressing adjacent structures with no signs of invasion. Ileocolectomy with partial mesenteric resection was performed. A histopathological and immunohistochemical analysis confirmed the diagnosis of mesenteric desmoid tumor.(AU)

Innovative hybrid technique for bile duct exploration in the treatment of choledocholithiasis

Introduction: Common bile stone disease (CBDS) is frequent and has potentially severe complications, such as acute biliary pancreatitis and cholangitis. Unnecessary and unplanned procedures should be avoided, so before choosing the best treatment of common bile duct lithiasis it is essential to have a proper diagnose. CBDS is currently treated by therapeutic endoscopic retrograde cholangiopancreatography (ERCP) or laparoscopic bile duct exploration (LCBDE). Results: The aim of this article is to present an innovative hybrid technique for common bile duct exploration, as an option for cases where the laparoscopic approach is not resolutive, avoiding the need for conversion to open approach technique. Conclusions: The hybrid technique has the same benefits as open and laparoscopic techniques, but without increasing material costs and with good resolution in complex cases of common bile duct stones.

Laparoscopic resection of gastrointestinal stromal tumors (GIST) of the small intestine: a case report

Although gastrointestinal stromal tumors (GISTs) are a rare type of cancer, they are the commonest mesenchymal tumors of the gastrointestinal tract (GIT). GISTs can affect any segment of the GIT, but the usual location is the stomach, followed by the small intestine. Surgical resection of the tumor is the gold standard treatment for localized GISTs, and in patients with inoperable and metastatic disease, imatinib mesylate is the standard treatment. Pathological diagnosis is based on morphology and immunohistochemical findings. We report the case of a 55-year-old man with jejunal GIST presenting with endophytic and exophytic growth, located in the proximal jejunum. He had history of melena, anemia and one episode of enterorrhagia, and was treated with surgical resection of the lesion. (AU)

Effect of Roux-en-Y gastric bypass in the control of erosive esophagitis

Introduction: Gastroesophageal reflux disease (GERD) is a multifactorial disease associated with environmental and genetic factors. Obesity is among the risk factors for its development, which also correlates with an increase in severity of clinical presentation and a higher incidence of complications associated with reflux. Methods: This historical cohort study included a sample of 249 patients who had undergone bariatric surgery using the Roux-en-Y gastric bypass technique at the Hospital São Vicente de Paulo, Passo Fundo, southern Brazil, from January 2014 to December 2015. Results: Of 249 patients, 77.9% (190 patients) were female and the mean age was 38 years. The occurrence of reflux esophagitis was 81.1% (196 patients) in the preoperative period and 31.3% (75 patients) in the postoperative period. With regard to bariatric treatment response to control moderate and severe esophagitis (grades B, C and D), there was a reduction in prevalence from 62 (25%) to 12 (5%) patients (p<0.05). Conclusions: Bariatric surgery using the Roux-en-Y gastric bypass technique is effective in the control of reflux esophagitis. Regression is observed mainly in cases of moderate and severe esophagitis. (AU)

Treatment of posterior gastric wall gastrointestinal stromal tumor with gastric sleeve: a case report

Gastrointestinal stromal tumors (GISTs) are the most common non-epithelial tumors of the gastrointestinal tract. The most usual location is the stomach, followed by the small intestine, where it may cause digestive bleeding and anemia. Surgical resection of the tumor is the gold standard treatment, and definitive diagnosis is based on immunohistochemical analysis of the surgical specimen. We report the case of a 53-year-old man with gastric GIST presenting with endophytic and exophytic growth, located at the posterior wall of the stomach, in the antrum-body transitional zone, treated with gastric sleeve.
