Resection of a giant nonparasitic splenic cyst by minilaparoscopy.

A female patient, 20 years old, with a history of a progressive increase in abdominal volume on the left side, starting 3 years ago, with no associated symptoms and no history of trauma. Ultrasonography and a computed tomography scan of the abdomen were performed, which revealed a large splenomegaly, and a partial minilaparoscopic splenectomy was indicated. We opted for unroofing of the cyst, and the procedure was uneventful, with a total surgical time of 47 min. The patient progressed clinically well, without abdominal pain, being discharged on the 2nd post-operative day.

A new hybrid mini-laparoscopic technique for Spigelian hernia.

We describe the original technique used for the treatment of a patient who presented with pain and bulging in the abdomen, who was diagnosed with Spigelian hernia (SH) using ultrasound. In this case, the hernia occurred in the anterolateral abdominal wall with herniation of the distal ileum and mesentery, in addition to a large right inguinal hernia. A mini-laparoscopic approach was proposed; due to Child-A hepatic cirrhosis, it was done by a hybrid technique, using a harmonic scalpel. The primary closure of the hernia defects was performed, followed by the placement of a polypropylene mesh in the preperitoneal space. The mesh was fixed. In this case, the inguinal hernia was homolateral to the SH. Following the surgery, the patient had no further complications, being discharged the day after the procedure.

Resection of giant hepatic cyst by hybrid minilaparoscopy.

A female patient, 59-year-old, was complaining of abdominal pain in the right hypochondrium and mesogastrium for 6 months. Ultrasonography and abdominal computed tomography were performed, both confirming a large hepatic cyst (10.6 cm × 7.6 cm × 7.3 cm) on the left lobe. A hybrid minilaparoscopic resection was proposed. We opted for unroofing the cyst, and the procedure was uneventfully performed, with a total surgical time of 60 min. In the post-operative the patient did well, with minimal abdominal pain, being discharged on the 5th post-operative day, after drain removal due to the use of intravenous antibiotic therapy.

Demographic and clinical characteristics of pulmonary arterial hypertension caused by schistosomiasis are indistinguishable from other etiologies.

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a serious pulmonary circulation disease caused by several etiologies, including schistosomiasis. The present study retrospectively evaluated the clinical and hemodynamic characteristics of patients with schistosomal PAH (PAH-Sch) compared to those of non-Sch PAH patients (non-Sch PAH). METHODS: Patients treated at the Pronto-Socorro Cardiológico de Pernambuco and diagnosed by right cardiac catheterization were divided into PAH-Sch and non-Sch PAH groups. Their socio-demographic and clinical characteristics, N-terminal-pro B-type natriuretic peptide (NT-proBNP), and echocardiography and hemodynamic parameters were retrospectively reviewed. RESULTS: Among the included 98 patients (mean age, 45 ± 14 years; 68 women [69.4%]), we found 56 PAH-Sch and 42 non-Sch PAH. The age distribution was heterogeneous in the PAH-Sch group, with patients predominantly ranging from 50-59 (p <0.004). Dyspnea was the most common symptom, reported by 92 patients (93.8%), and commonly present for over two years prior to diagnosis. Clinical symptoms were similar in both groups, with no differences in functional class, pulmonary artery systolic pressure (p = 0.102), 6-minute walk test score (p = 0.234), NT-proBNP serum levels (p = 0.081), or hemodynamic parameters. CONCLUSIONS: Patients with PAH-Sch present clinical, laboratory, and hemodynamic profiles similar to those with PAH resulting from other etiologies of poor prognosis. PAH is an important manifestation of schistosomiasis in endemic regions that is often diagnosed late.

Which Cholecystectomy do Medical Students Prefer?

INTRODUCTION: This study was undertaken to identify which minimally invasive technique medical students prefer for cholecystectomy and what factors determine their decision. METHODS: Brazilian medical students watched a video reviewing the advantages and disadvantages of six different surgical approaches to cholecystectomy: open surgery, conventional laparoscopy, mini-laparoscopy (MINI), single-incision laparoscopic surgery, natural-orifice transluminal endoscopic surgery, and robotic surgery. Respondents then answered questions about hypothetical situations in which the participants would be submitted to elective cholecystectomy. RESULTS: One hundred eleven medical students completed the survey, 60 females (54%) and 51 males (46%). Most students were 19-26 years old. When asked whether they would consider an open cholecystectomy if minimally invasive surgery (MIS) techniques were available, only 9% answered yes. Senior medical students were the least willing to consider open surgery (P = .036). When asked if they would prefer conventional laparoscopy, MINI, or robotic surgery for their cholecystectomy, 85% of the women and 63% of the men chose MINI (P = .025). When asked if they would consider a single-incision laparoscopic surgery or natural-orifice transluminal endoscopic surgery approach, 94 respondents (84%) answered no. When asked to rank which factors they consider the most important when choosing a surgical technique, they ranked safety of the procedure first (58%) and surgeon experience second (30%). CONCLUSION: When Brazilian medical students were asked to select a surgical approach for cholecystectomy, most chose MINI. The preference for MINI was strongest amongst female medical students. Both female and male medical students ranked safety as the most important factor.

Cognitive Dysfunction and Single Nucleotide Polymorphisms in Hepatitis C Virus-Infected Persons: A Systematic Review.

The aim of this study was to realize a systematic review to identify data reported in the literature involving people infected by hepatitis C virus (HCV) with cognitive dysfunctions and single nucleotide polymorphisms (SNPs). The research was realized in six databases and the selection of studies was performed in two stages. Initially, we searched indexed articles from the following electronic databases: SciELO, MEDLINE, PubMed, HighWire, LILACS, and ScienceDirect. Then the articles were completely read and those that did not meet the eligibility criteria were excluded. Therefore, 5,669 articles were obtained and, of these, 25 were selected. Finally, one article involving people with HCV and cognitive impairment was included in the review. The frequency of the APOE-ɛ4 allele in people with HCV and mild liver disease was significantly lower in those with work memory impairment (p = 0.003) and attention (p = 0.008). This situation differs from other studies that showed an association between ɛ4 allele high frequency and cognitive decline. Thus, studies with larger samples involving people with HCV, cognitive alterations, and SNPs are necessary, in view of the lack of this theme in the literature and the divergences in the findings.
