CMOS pixel sensors are being developed for the CBM Micro-Vertex Detector (MVD). They provide the high resolution required to reconstruct efficiently decay vertices of short-lived particles, such as charmed mesons. The present R&D is mainly driven by the severe running conditions expected in the vicinity of the experimental target. The most significant(More)
Sciatic nerve endometriosis is rare but must be included in the sciatic pain aetiology diagnosis. Typically the patient's sciatic pain is cyclic. Electromyography and computed tomographic scanning or nuclear resonance imagery contribute to the diagnosis. Different mechanisms of this localization have been proposed. The patient often requires conservative(More)
Fibromatosis (desmoid tumors) is a rare entity expressing a mesenchymatous proliferation. The breast is an exceptional localisation. The origin is either the gland itself or the breast is an extension of a desmoid tumor originating from the chest wall or shoulder. Etiology is still unknown. Clinical and radiological features mimic the breast carcinoma.(More)
We carried out a retrospective analysis of 3,231 cases of cesarean section between 1994 and 1997, to assess the maternal mortality and morbidity associated with this intervention. The frequency of cesarean delivery was 12.4%. The indications for cesarean section were of three types: elective indications (627 cases, 19.4%), emergency indications (454 cases,(More)
A monolithic active pixel sensor operating in current mode for charged particle detection is described. The sensing element in each pixel is an n-well/p-sub diode with a PMOS transistor integrated in an n-well. The drop of the n-well potential from the collection of charge modulates the transistor channel current. Each pixel features two current mode memory(More)
Phyllode tumors of the breast are fibroepithelial tumors similar to fibroadenomas but with a predominant conjunctive tissue component. The aim of this work was to determine the specific diagnostic, therapeutic and prognostic features of this tumor. A retrospective series of 41 cases was collected in the gynecology-obstetrics ward from 1980 to 1991. The(More)
Swift, high resolution CMOS pixel sensors are being developed for the CBM Micro Vertex Detector (MVD), allowing for high density particle tracking. Designed at IPHC, the sensors are manufactured by the CMOS industry and can be thinned down to ≤ 50 μm. To accommodate the data rate, the signals delivered by the sensors are discriminated before being filtered(More)
We carried out a prospective study of 200 pregnant women who required induction of labor at full term, at the Lalla Meryem maternity unit of the Ibn Rochd University Hospital, Casablanca, between January 1st 1996 and June 30th 1997. The aim of this study was to evaluate the efficacy, tolerance and acceptance of misoprostol (Cytotec) as a drug for inducing(More)
This study involved an analysis of 25 cases of sarcoma of the uterine body collected at the Gynecology and Obstetrics Clinic of the Ibn Rochd CHU teaching hospital, Casablanca (Morocco) during a 15-year period (1977-1992). These are unusual malignant tumours (accounting for only 0.9% of uterine cancers) which occur after the menopause and have an appalling(More)
