Mis-diagnosed giant ovarian cyst and ventriculoperitoneal shunt malfunction.

Abdominal pseudocysts are common complications of ventriculoperitoneal shunt (VPS). We report the case of a 37-year-old woman treated by VPS for congenital obstructive hydrocephalus, who presented shunt dysfunction related to a voluminous abdominal cyst initially diagnosed as cerebrospinal fluid pseudocyst. The cyst was drained and the VPS was removed after endoscopic third ventriculocisternostomy (ETV).

[Systemic treatments of the vasospasm].

Cerebral vasospasm, a recognized complication of aneurysmal subarachnoid haemorrhage, can lead to delayed ischaemic neurological deficit, and death. The systematic administration of nimodipine confers a modest but real benefit against delayed ischaemic damage. When vasospasm occurs, triple-H therapy (hypervolaemia, hypertension, and haemodilution) has long been advocated in order to increase flow, but its usefulness remains unclear.

[Follow-up study of head-injured children].

The authors reviewed in a retrospective study 61 cases of severely head injury children who where admitted in the rehabilitation centre to evaluate the outcome 1 and 5 years after the brain injury. Neurologic and neuropsychologic status of children was assessed ad admission, 1 and 5 years later. Duration on intubation and age at time of head trauma were the worst functional prognosis.

[Recombinant hirudin in neurosurgery].

We report the case of a 70-year-old woman with paraplegia resulting from spinal cord compression secondary to an epidural haematoma. Because of an arrhythmia, a mitral valve replacement and the high risk of venous thrombosis, an anticoagulant treatment was introduced postoperatively. The patient having previously developed an type II heparin-induced thrombocytopaenia, a treatment by lepirudine was established successfully.

[Role of the regulation in the management of patients with severe head injuries].

The regulator of the emergency medical ambulance service is involved in the various steps of the initial management of severe head trauma patients: handling calls, basic life support, prehospital advance life support, transport and hospital admission. The management is rapid (helicopter transports) coherent and adapted (adherence to the guidelines for severe head injury), and considers of local difficulties (geographical, possibility of admission to trauma centres), with the aim of improving the outcome of severely head-injured patients.

Enhanced levels of radiation-induced G2 phase delay in ataxia telangiectasia heterozygotes.

Ataxia telangiectasia (AT) is a multiform genetic disease characterized by immunodeficiency, cerebellar abnormalities, and cancer predisposition. Heterozygotes also have an increased risk of developing several different cancers. It has been estimated that as many as 18% of all patients with breast cancer, the cancer most clearly associated with AT heterozygotes, may be carriers of the AT gene.

Normal inhibition of DNA synthesis following gamma-irradiation of radiosensitive cell lines from patients with Down's syndrome and Alzheimer's disease.

Inhibition of DNA synthesis was studied in gamma-irradiated lymphoblastoid cells from patients with Alzheimer's disease and Down's syndrome. A normal biphasic pattern of inhibition was observed over a dose range of 0-4 krad of gamma-rays in all of the cell lines. 3 out of 4 Down's and all the Alzheimer's cell lines were shown to be hypersensitive to ionizing radiation based on induced chromosomal aberrations.
