The effect of performing corrections on reported uterine cancer mortality data ...

Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2...

Aneurysmal bone cysts of the spinal canal.

Aneurysmal bone cysts (ABC) are rare bone tumors of controversial pathogenesis. In 15% of cases, they are localized in the vertebrae. Despite the absence of anaplasia, their volume and localization are often responsible for incomplete surgical resection. The authors present 5 cases of primary vertebral ABC, 4 females and one male, localized in cervical (3 cases), dorsal (1 case) and lumbar (1 case) spine. Sympt...

Perimesencephalic hemorrhage.

Among 293 subarachnoid hemorrhages admitted to the Neurology and Neurosurgery departments of Sta Maria Hospital, 108 patients had a normal cerebral angiography. Twenty-three meet the radiological criteria for perimesencephalic hemorrhage (center of the hemorrhage located in front of the mesencephalon, without blood in the interhemispheric and lateral sylvian fissures, nor significant intraventricular hemorrhage...

Medical schools: training workshops--A comment.

Intravascular therapy of giant cerebral aneurysm.

The endovascular therapy in cerebral aneurysms has met significant technical progress, specially related with new microcatheters and different types of detachable balloons. Reviewing seven cases of giant cerebral aneurysms treated by intra arterial approach, the authors present their results pointing out and discussing the different angiosurgical therapy that can actually be used. ; The endovascular therapy in...

Spinal epidural empyemas.

We report ten patients harbouring spinal epidural abscess, aiming to evaluate the factors that may lead to an early diagnosis and that can eventually influence the prognosis. There were seven males and 3 females, with ages comprised between 17 and 66 years. Abscesses were localised mainly in the dorsal region. The most important predisposing factors were infections or other disorders know to be related with com...

A diaphragmatic pacemaker in the treatment of ventilatory failure.

Diaphragmatic Pacing was used to treat ventilatory failure in a young boy with bilateral diaphragmatic palsy secondary to cervical cord injury, on chronic mechanical ventilation for 6 months. The indications for diaphragmatic pacing in ventilatory failure were discussed, as well as the assessment of phrenic nerve integrity and the pacing schedules utilized to slowly improve the diaphragm endurance and achieve a...

Spinal cord tumors. Anatomoclinical study.

The authors review 36 cases of intramedullary spinal tumours, 17 ependymomas, 12 astrocytomas, 6 hemangioblastomas and 1 metastasis of leiomyosarcoma. The tumours were localized in the cervical region in 19 patients, in the thoracic region in 10 in the lumbar region in 4, and in the conus medullaris in 3. All patients presented a clinical picture of myelopathy. No differences were observed between the different...
