Spinal cord injury: From inflammation to glial scar.

Background: Glial scar (GS) is the most important inhibitor factor to neuroregeneration after spinal cord injury (SCI) and behaves as a tertiary lesion. The present review of the literature searched for representative studies concerning GS and therapeutic strategies to neuroregeneration.

Methods: The author used the PubMed database and Google scholar to search articles published in the last 20 years.

Spinal cord injury: epidemiological study of 386 cases with emphasis on those patients admitted more than four hours after the trauma.

We studied 386 cases of spinal cord injury to analyze the follow up of the patients admitted most of the time more than four hours, the majority of the injuries happening far from the attending health service and first specialized care received long after the accident. This is a clinical study based on data collected during hospitalization of the patients, operated or not, in a Brazilian public health service. The lesion mainly seen was fracture and dislocation, isolated or on multiple levels, and the most important clinical complications were due to respiratory failure and hypotension, especially because 73.

[Paracoccidioidomycosis in cerebral hemisphere and brainstem: case report].

We report on a 36 years-old man that had been at the Amazon forest four years before. Six months before the admission he had developed a progressive quadriparesis, gait ataxia, dysphagia, dysarthria, difficulty in breathing and hiccup. The gadolinium-enhanced T1-weighted MRI showed a lesion into the right parietoccipital area and another into the medulla, that was the largest.

Hemodynamic parameters and neurogenic pulmonary edema following spinal cord injury: an experimental model.

Neurogenic pulmonary edema is a serious and always life-threatening complication following several lesions of the central nervous system. We report an experiment with 58 Wistar-Hanover adult male rats. Two groups were formed: control (n=4) and experimental (n=54).

Importance of anesthesia for the genesis of neurogenic pulmonary edema in spinal cord injury.

There are reports describing both provocation and inhibition of neurogenic pulmonary edema by anesthetic drugs. Therefore, we compared the effect of two types of anesthesia on the formation of neurogenic pulmonary edema in rats with balloon-induced acute spinal cord injury. Animals with sham procedure (group 1) were anesthesized by intraperitoneal sodium pentobarbital.

[Schwannoma of brachial plexus: report of two cases].

Schwannomas, neurinomas or neurilemmomas are benign peripheral nerve tumors. The literature report some cases associated with neurofibromatosis 2. We report two cases of cervical schwannoma originating from the brachial plexus unassociated with neurofibromatosis.

Schwannoma of the craniocervical junction: surgical approach of two cases.

We report two cases of craniocervical junction schwannomas with a special focus on the surgical approach. The patients underwent a far-lateral approach in the sitting position that facilitated the lesion removal. This report is meant to improve the understanding of this surgical technique as well as improve awareness of its usefulness for similar cases.

[Foreign body in the orbital cone: case report].

Orbital injuries may be associated with the presence of foreign bodies in which long retention leads to damages such as loss of vision or cerebral abscess. We present the case of a 21-year-old male patient that developed ptosis, limitation of movements and an inflammatory reaction in the right eye after being hit by a tree branch. A CT scan of the orbits revealed an increased density in the right orbital cone.

[Eosinophilic granuloma of the cervical spine: case report].

Eosinophilic granuloma (EG) is a benign condition of histocytes proliferation localized or multifocal. It is presents in the cervical spine in 1.5%-20% of the cases of EG.

[Tumoral form of neurocysticercosis: case report].

The authors report a case of neurocysticercosis by giant cyst (3.9 x 3.4 cm), where there were clinical manifestations of increased intracranial pressure and characteristics of image in computed tomography of cranium of expansive process with mass effect in central nervous system (CNS).
