[Operating rooms during the second half of the 20th century and its change with surgical advances].

With the rise of new specialities after the World War, the number of OP rooms increases. They became gathered on the basement of buildings near the central sterilisation. To enter the OP room, everyone passes through the dressing "sas".

Activation of large conductance sodium channels upon expression of amiloride-sensitive sodium channel in Sf9 insect cells.

The amiloride-sensitive epithelial sodium channels (ENaC) mediate Na(+) reabsorption in epithelial tissues including distal nephron, colon, lung, and secretory glands and plays a critical role in pathophysiology of hypertension and cystic fibrosis. The ENaC is a multimeric protein composed of alpha-ENaC, beta-ENaC, and gamma-ENaC subunits. To study the biochemical properties of the channel, the subunit cDNAs of rat colon ENaC (rENaC) were subcloned into baculoviruses, and the corresponding proteins were expressed in Sf9 insect cells.

Expression of amiloride-sensitive sodium channel: a strategy for the coexpression of multimeric membrane protein in Sf9 insect cells.

The amiloride-sensitive epithelial sodium channel (ENaC) mediates Na(+) reabsorption in many epithelial tissues including the distal nephron, colon, lung, and secretory glands and plays an important role in pathophysiology of hypertension and cystic fibrosis. The ENaC is a multimeric integral membrane protein formed by the association of highly homologous,alpha-, beta-, and gamma-ENaC subunits. Here we explored the Sf9 insect cell-baculovirus expression system as a source to obtain high yields of recombinant ENaC for functional and structural studies.

[Peroperative echography in neurosurgery. Its value and applications 10 years later].

Intraoperative ultrasound imaging has many advantages over other imaging methods. The authors present their experience from hundred patients over ultrasound scanning. A large iconography is exposed.

[Cervical osteoid osteoma. Report of a case and review of the literature].

One case of a cervical osteoid osteoma is presented and compared with infrequent similar cases from the literature. The authors recall the diagnosis difficulties, facing a long standing not explained neck pain due to poor neurological and current radiological informations. The interest of the bone scintigraphy, CT scan and M.

[Intramedullary neurinoma. Apropos of a case. Review of the literature].

The authors present a case of intramedullary neurinoma. A 44 years old patient was admitted for lumbar pain and bilateral sciatica. Neurological examination was normal except for dysuria and diminution of Achilles tendon reflexes.

[Solitary plasmacytoma simulating pituitary adenoma].

A case of solitary plasmocytoma of the sphenoid is reported, masquerading as pituitary adenoma. At the time of surgery, the patient had no findings of multiple myeloma. The tumor was removed by trans-sphenoidal route and radiotherapy delivered.

[Cauda equina syndrome complicating cutaneous T-cell lymphoma (mycosis fungoides)].

Authors present a case of a cutaneous T. cell lymphoma (mycosis fungoides) complicated by a cauda equina syndrome. Crural and sciatic radicular pain were due to epidural lumbar involvement by tumoral process.

[Intervertebral biopolymer implant for arthrodesis. A study of 45 cases].

The B.O.P.

Spinal subdural hematoma.

The authors report a case of spinal subdural hematoma in a 51-year-old man who experienced a sudden onset of back pain accompanied by vomiting and headache without paralysis or paraparesis. CT Scan, myelography and MRI revealed a subdural hematoma at the levels of 6th, 7th and 8th thoracic vertebrales. Laminectomy allowed the removal of an encapsulated cyst formation filled with xanthochromic fluid and some blood clots.

[Chronic subdural hematoma in the elderly and computerized tomography. Study of 80 cases].

The pathogenesis of chronic subdural hematoma, especially the reason why it becomes chronic is still under discussion. A series of 80 patients older than 60 years (47% older than 75 years) were studied clinically and by CT. As compared with angiography, CT allows the subdural hematoma to be detected earlier.

[Cerebrospinal fluid fistula--indications for treatment with lumbar puncture and drainage. Report of 66 cases].

The authors present a series of 66 cases of cerebrospinal fluid fistulas. Ways of localizing the fistula as well as different therapeutic methods are studied. They insist on the efficiency of external lumbar drainage of the cerebro-spinal fluid which permits a fair number of patients to recover without surgery.

[Cervical chordoma. Apropos of a case].

The chordomas are malignant tumors arising from the remnants of the posterior spinal chord. The chordomas of the cervical spine are rare (5% of the spinal chordomas). A new case of spine chordoma at C5 level in a 76 years old woman is reported.

[The injured cervical spine with and without lesions of the nerve structures. Clinical results of surgical therapy].

The operative treatment of the cervical spine injuries with and without neurological deficit was active developed in the last 25 years. The surgical management has been determined by the type of deformity, and also by the anatomical and functional specialties. The indication, the diagnostical and therapeutical strategy and the results of surgical treatment of 304 cases are discussed.

[Rupture of neoplastic intracranial aneurysm caused by metastatic uterine choriocarcinoma].

Authors report a case of 18 years old woman with intracranial neoplastic aneurysm. Its rupture occurred one month after delivery, and the diagnosis of metastatic aneurysm from choriocarcinoma was made by pathologist. The craniotomy has allowed to remove the hematoma and the aneurysm with good immediate follow-up.

[Glioblastoma of the cerebellum in a child. Apropos of a case. A review of the literature].

Authors present a case of glioblastoma of cerebellum in a 11-year old child. Symptoms and signs are those of other tumors of posterior fossa. Diagnosis was made by CT Scan and pathologist.

[Hand-Schüller-Christian disease with tumor localization in the posterior fossa].

A 19-year-old girl had been suffering since the age of 4 from Hand-Schüller-Christian disease. The condition was diagnosed by biopsy of a cranial bone lacuna. Later on, she developed diabetes insipidus and bilateral exophthalmos, both being typical signs of Hand-Schüller-Christian disease.

[Primary cerebral lymphoma. Diagnostic and therapeutic values. Apropos of 4 cases].

The authors report four recent cases, of primary cerebral Lymphoma discovered since the use of the C.T. scan.
