Multiple sclerosis patients who become pregnant experience a significant decrease in relapses that may be mediated by a shift in immune responses from T helper 1 to T helper 2. Animal models of multiple sclerosis have shown that the pregnancy hormone, estriol, can ameliorate disease and can cause an immune shift. We treated nonpregnant female multiple(More)
OBJECTIVE To evaluate the relative sensitivity of MR scanning for multiple sclerosis (MS) at 1.5 Tesla (T) and 3.0 T using identical acquisition conditions, as is typical of multicenter clinical trials. METHODS Twenty-five subjects with MS were scanned at 1.5 T and 3.0 T using fast spin echo, and T(1)-weighted SPGR with and without gadolinium contrast(More)
Background: The purpose of this study was to determine whether laparoscopy could improve our ability to diagnose and treat perforations of the small bowel. Methods: From 1985 to 2001, among 250 patients admitted for a blunt abdominal trauma, 195 surgical explorations were performed, comprising 42 laparoscopies. On admission, 108 patients underwent an(More)
AIM OF THE STUDY The aim of this prospective non-randomized study was to compare Stoppa's technique to laparoscopic approach in totally extraperitoneal repair of bilateral inguinal hernia. PATIENTS AND METHOD From December 1996 to December 1998, 117 consecutive patients with 234 hernias underwent either Stoppa's technique (74 patients) or a totally(More)
Many high-level visual regions exhibit complex patterns of stimulus selectivity that make their responses difficult to explain in terms of a single cognitive mechanism. For example, the parahippocampal place area (PPA) responds maximally to environmental scenes during fMRI studies but also responds strongly to nonscene landmark objects, such as buildings,(More)
We reported a case of papillary and cystic tumor (Frantz's Tumor) associated with familial adenomatous polyposis in a young man, 29 years old. This case emphasized the interest of fine needle biopsy and the difficulties for determination of the final pathology. Close long term follow up is essential as local recurrencies and metastasis in the long term had(More)
From 1985 to 1991, bilateral surgical biopsy of the superomedial group of superficial inguinal lymph nodes, considered to be the first draining nodes, was performed in 24 patients with clinical stage T1-3 N0 M0 squamous cell carcinoma of the penis at the same time as surgical treatment of the primary. This procedure was technically successful in every case,(More)
Locoregional extensions are often observed in tumors of the duodenojejunal angle, either because of their anatomic situation or in cases diagnosed late. Endoscopic and radiographic explorations (basically abdominal CT scan) are indicated to search determine the degree of extensions to neighboring organs and vessels. Colic and mesocolic involvement are at(More)
The authors report on a case of hepatic cyst with neonatal diagnosis. The cyst resulted in neonatal respiratory distress leading to emergency surgery (partial cystectomy). Histological examination revealed the presence of a cystic hamartoma. This cases provides the basis for a discussion on the diagnosis of a neonatal abdominal cystic tumor and the nature(More)
The authors report about two observations of cystic lymphangioma of the right colon. The patients complained of intermittent abdominal pain. Preoperative diagnosis is based on endoscopic findings (2 cases) and computed tomography films (1 case). A colonic carcinoma is associated in one case. Endoscopic polypectomy will be curative for pedunculated or small(More)
