Our anatomic findings have led us to define conflictual relations that may be encountered in their course by the pudendal n. and its branches. Starting from the clinical study of a group of patients suffering from chronic perineal pain in the seated position, we have defined, beginning with the cadaver, three possible conflictual settings: in the(More)
AIMS The diagnosis of pudendal neuralgia by pudendal nerve entrapment syndrome is essentially clinical. There are no pathognomonic criteria, but various clinical features can be suggestive of the diagnosis. We defined criteria that can help to the diagnosis. MATERIALS AND METHODS A working party has validated a set of simple diagnostic criteria (Nantes(More)
BACKGROUND Most military helmets are designed to prevent penetration by small firearms using composite materials in their construction. However, the transient deformation of the composite helmet during a non penetrating impact may result in severe head injury. METHOD Two experimental designs were undertaken to characterize the extend of injuries imparted(More)
This 7-year-old boy with Hajdu-Cheney syndrome presented with cervical syringomyelia related to rapidly progressing platybasia. Decompressive craniectomy provided temporary improvement, and his clinical status was eventually stabilized after external immobilization, according to findings at 2.5 years of follow up. In a review of the literature the authors(More)
We examine whether firms that emphasize decision making based on data and business analytics (“data driven decision making” or DDD) show higher performance. Using detailed survey data on the business practices and information technology investments of 179 large publicly traded firms, we find that firms that adopt DDD have output and productivity that is 56%(More)
Neuropathic perineal pains are generally linked to suffering of the pudendal nerve. But some patients present pains described as a type of burning sensation located more laterally on the anal margin and on areas including the scrotum or the labiae majorae, the caudal and medial parts of the buttock and the upper part of the thigh. These pains extend beyond(More)
Perineal pain is the basis of presentation to different specialities. This pain is still rather unknown and leads the different teams to inappropriate treatments which may fail. For more than twenty years, we have seen these patients in a multidisciplinary consultation. Our anatomical works have provided a detailed knowledge of the nervous supply of the(More)
Intraoperative cholangiograms were studied in 250 patients. Analysis of the data obtained led to the establishment of a protocol for intraoperative cholangiography aimed at identification of anatomical anomalies and variations. Diagnosis of the latter must be achieved in order to avoid possible intraoperative complications. The common hepatic duct was(More)
The internal thoracic a. is much used in cardiac surgery because of its anatomic position, but its mobilisation may lead to devascularisation of the sternum. The aim of this study was to establish a precise systematisation of the vascularisation of the sternum by means of dissections and radiography after injection of contrast medium in 15 subjects. It is(More)
In 1989, we reported our thoughts on the neurophysiological and anatomic aspects of pudendal nerve involvement in certain types of perinal pain. Since that time, the surgical approach has been modified. Here we report our follow-up of 40 patients with 48 operated nerves. Follow-up ranged from 6 months to 7 years and outcome revealed improvement in 67% and(More)
