Neurosurgical stress and immune function.

The present study was carried out in 31 neurosurgical patients with unaffected consciousness and concerned by the severity of their condition. The severity of stress was established by the comparison between the pre- and postoperative peripheral blood lymphocyte populations and subpopulations (B, T, Th lymphocytes, serum complement and circulating immune complexes). The peripheral blood lymphocyte populations and subpopulations were determined by the technique of sheep red blood cell rosette.

Unilateral exophthalmos in a diabetes case with major ocular complications: diabetic retinopathy and neovascular glaucoma. Case report.

Unilateral exophthalmos associated with an inflammatory pseudotumoral process in a woman with insulin-dependent diabetes diagnosed 30 years earlier is reported. The discussion is focussed on the complications: diabetic retinopathy and neovascular glaucoma as well as on the therapy applied.

Intraorbital metastases.

Intraorbital metastases are rare. Tumors that metastasize more frequently in the orbit are: tumors of the breast, thyroid, prostate, spinocellular epithelioma, urinary bladder and Ewing sarcoma with an orbital location. The dominant feature of intraorbital metastases is exophthalmos.

Posterior fossa extradural hematomas in children: report of nine cases.

Extradural post-traumatic posterior fossa hematoma is a rare condition estimated to complicate about 0.13% of all craniocerebral injuries, and represents 5.8% of the entire group of extradural hematomas in our records.

Abnormal somatosensory evoked potentials in amyotrophic lateral sclerosis.

The sensory symptoms and the involvement of the sensory tracts in amyotrophic lateral sclerosis (ALS) were much debated by various authors. The SEPs were studied in 10 patients with ALS by percutaneous stimulation of the median and tibial nerves. The SEPs were recorded at: Erb's point, cervical level (CII), lumbar level (L1) and parietal level.

Cerebral dysfunction revealed by EEG mapping in the schizoform epileptic psychosis.

Twenty schizophrenia-like psychotic patients suspected of epilepsy were explored using EEG techniques (recordings in the 10-20 International System, source derivation, EEG mapping and EEG spectral reaction mapping by photic and somesthetic stimulation). In 16 of them, latent epileptic disorders were found. EEG spiking foci could be located either: (a) in temporal, (b) fronto-basal, or (3) in the sagittal-line leads.
