Percutaneous Foramen Ovale Puncture: Usefulness of Intraoperative CT Control, in the Eventuality of a Narrow Foramen.

BACKGROUND: Balloon compression of the gasserian ganglion has been a well-established percutaneous treatment of trigeminal neuralgia since the 1980s. However, puncture of the foramen ovale by conventional single-plane fluoroscopy can be difficult in cases of local anatomic abnormalities. CASE PRESENTATION: We present the case of a 49-year-old woman diagnosed with idiopathic trigeminal neuralgia refractory to pharmacological treatment. After failure of puncture by conventional fluoroscopy for percutaneous gasserian ganglion balloon compression due to a narrow foramen ovale, the patient was submitted to puncture guided by computed tomography. CONCLUSION: Alternative imaging methods, such as computed tomography, should be considered when puncture of the foramen ovale by conventional single-plane fluoroscopy fails, to minimize the risk of potential complications triggered by frustrated puncture attempts.

Bladder perforation by ventriculoperitoneal shunt.

BACKGROUND: Bladder perforation by ventriculoperitoneal shunt is a rare complication that has been describe in 19 cases in prior literature. CASE DESCRIPTION: This work describes the case of a 4-month-old baby who presented with extrusion of the distal catheter through the urethra. The patient underwent a laparotomy; the catheter was cut close to the bladder wall and repositioned into the peritoneal cavity. The bladder wall was sutured, and the remaining distal portion of the catheter was removed through the urethra. DISCUSSION AND CONCLUSION: Based on this single experience and a literature review, the authors classified the clinical signs and symptoms of bladder perforation by the ventriculoperitoneal shunt catheter. Finally, the authors propose a more conservative approach for this rare complication.

Analysis of the ergonomic usage of the ARMflex in the odontological area.

The aim of this paper is to analyze the importance and applicability of ARMflex in the odontological area and its influence in preventing or stopping the involuntary habit of improperly positioning the hand under the face or under the pillow. The ergonomic usage of ARMflex influences the design in odontological areas and innovates in the semi-immobilization of the patient to prevent future orthodontic problems.

Câncer colorretal: resultados da avaliação patológica padronizada de 521 casos operados no Hospital das Clínicas da UFMG / Colorectal cancer: results of standardized pathologic evaluation of 521 patients underwent surgery at Hospital das Clínicas, Federal University of Minas Gerais

INTRODUÇÃO: A incidência e a mortalidade por câncer colorretal (CCR) têm apresentado, em todo mundo, uma tendência ao crescimento, em especial em países desenvolvidos e em áreas urbanas de países menos desenvolvidos. O estudo das características anatomopatológicas do tumor é importante para o estadiamento e a definição da terapêutica a ser empregada. O objetivo deste estudo é avaliar as características anatomopatológicas de peças cirúrgicas de ressecções colorretais por neoplasias no Hospital das Clínicas da Universidade Federal de Minas Gerais. RESULTADOS: Foram avaliadas 521 peças cirúrgicas de ressecções colorretais. A idade média dos pacientes foi de 62,47 (±14,67) anos, sendo 302 (58 por cento) deles do sexo feminino. Os tumores do cólon esquerdo foram os mais comuns (340 [65,3 por cento]). Houve predominância de adenocarcinomas (457 [87,7 por cento]), úlcero-infiltrativos (176 [33,8 por cento]), moderadamente diferenciados (396 [76 por cento]), pT3 (316 [60,7 por cento]) e pN0 (213 [40,9 por cento]). O número médio de linfonodos dissecados por peça cirúrgica foi de 22,13 (±14,27). CONCLUSÕES: Os dados de nossa casuística de CCR não diferiram do que foi relatado na literatura. Em síntese, o CCR foi mais comum em mulheres do que em homens, acometeu com maior frequência o cólon esquerdo, e o tipo predominante foi o adenocarcinoma moderadamente diferenciado, pT3 e pN0.

INTRODUCTION: The incidence and mortality of colorectal cancer (CRC) have shown, worldwide, an upward trend, particularly in developed countries and urban areas of developing countries. The study of tumor's pathological characteristics is important for staging and the definition of the proper therapy to be used. The aim of this study is to evaluate the pathologic features of surgical specimens of colorectal resections due CRC at Hospital das Clínicas, Universidade Federal de Minas Gerais. RESULTS: We evaluated 521 surgical specimens of colorectal resections. The mean age of patients was 62.47 (± 14.67) years, 302 (58 percent) were female. Tumors of the left colon were more common (340 [65.3 percent]). There was a predominance of adenocarcinoma (457 [87.7 percent]), ulcero-infiltrative (176 [33.8 percent]), moderately differentiated (396 [76 percent]), pT3 (316 [60.7 percent]) and pN0 (213 [40.9 percent]). The average number of dissected lymphonodes per surgical specimen was 22.13 (± 14.27). CONCLUSIONS: Data from our series of CRC did not differ from what was reported in the literature. In summary, the CRC was more common in women than in men, affecting most frequently the left colon, and the predominant type was moderately differentiated adenocarcinoma, pT3 and pN0.
