A retrospective analysis of 22 patients with central nervous system (CNS) non-Hodgkin's lymphomas seen from 1978 to 1989 at Hamamatsu University Hospital was carried out. These were corresponding to 16% (22/137) of non-Hodgkin's lymphomas treated by irradiation during the same period. Six patients had primary intracranial involvement, six had secondary one, five had leptomeningeal involvement and five had spinal cord compression. Median survival of these groups 29 months, 7 months, 6 months and 4 months, respectively. On the case primary intracranial involvement, neurological signs and symptoms and performance status (PS) were improved in most patients. Whole brain irradiation with a dose of 45 Gy to 50 Gy followed by systemic chemotherapy was considered as effective treatment modalities. On the other hands, for the secondary intracranial lymphomas, clinical symptoms and PS were excellently improved by radiation therapy, however these were not reflected to survival. The conditions having primary site on gastrointestinal tract and relapse as systemic dissemination were considerable risk factors for the control of CNS involvement. For these patients, prophylactic chemotherapy should be necessary. Improvement of PS on patients with leptomeningeal lymphomas was obtained in only 3 of 5 cases. These were treated by irradiation on whole spine or neuroaxis and intrathecal MTX injection. We observed 2 cases dying from cerebrovascular accident and one case from leukoencephalopathy. This showed that such combination therapy should be carefully attempted. Five patients having spinal cord compression suffered from paraplegia and none of them had been improved on their symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical features of six women with spinal cord meningioma are presented. These cases comprise the neurosurgical experience of one of the authors (B.B.) over approximately a 3-year period. Median age was 76 years with a range of 65-89 years. Previous reports of this disorder have not emphasized the occurrence of this tumour in the later decades. A notable feature was delay in diagnosis. Only one patient had a correct diagnosis of spinal cord compression prior to admission. Incorrect diagnoses included diabetes mellitus, osteoarthritis, degenerative spinal disease, gait disturbance secondary to fall and a thalamic cerebrovascular accident. Gait disorders at presentation included paraparesis, wide-based gait and unclassified disability. All patients had pyramidal tract signs and five had a truncal sensory level. Plain radiographs of the spine were unhelpful and can dissuade the physician from the diagnosis. All tumours were in the thoracic region. Surgery resulted in cure in all patients and diverted one patient from planned institutional care. Spinal cord meningioma should be considered in elderly patients presenting with gait disorder.

During a 40-month period, in 24 of 643 (4%) newly diagnosed patients with systemic cancer younger than 18 years of age (range: 3 months to 17 years) spinal cord disease developed. Patients with spinal cord disease included 21 children with metastatic spinal cord compression, two with treatment-related transverse myelopathies, and one with an anterior spinal artery stroke. Spinal cord disease occurred in 13 of 102 children (12%) with sarcomas, six of 82 (7%) with neuroblastomas, and four of 94 (4%) with lymphomas. Spinal cord compression occurred as the presenting sign of malignancy in six children (four with sarcomas and two with lymphomas). In the remaining 15 patients, cord compression occurred a median of 13 months after initial diagnosis, and in four patients it occurred at the time of first relapse. Symptoms of metastatic cord compression included back pain in 17 patients (80%), weakness in 14 (67%), sphincter dysfunction in 12 (57%), and sensory abnormalities in three (14%). Findings on plain radiographs of the spine were abnormal in only seven of 20 patients with cord compression, and myelography was needed to differentiate compression from other causes of spinal cord disease. Treatment included high-dose corticosteroids followed by operation (seven patients) or radiotherapy (14 patients). After treatment, nine of 15 nonambulatory patients became ambulatory, and five of 10 incontinent patients regained sphincter control. None of the patients with nonmetastatic spinal cord disease had a satisfactory outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Hypertrophy or calcification of the ligamentum flavum may be a cause of spinal cord compression. Most cases have been reported to occur in either the cervical or thoracolumbar region. We report an unusual case of a 59-year-old man admitted to the rehabilitation service with a recent diagnosis of right cerebrovascular accident with left hemiparesis. The patient had a history of gait disturbance, motor weakness, and bowel/bladder changes. Admission FIM scores were approximately 62 with complete dependence in mobility (ie, transfers) and locomotion. Fluctuating changes in his neurological status were observed; further testing led to an uncommon diagnoses of thoracic radiculomyelopathy caused by calcification of the ligamentum flavum. This diagnosis, although rare, should be considered in the diagnosis of patients suspected to have spinal cord compression.

Neurologic complications occur frequently in patients with cancer. After routine chemotherapy, these complications are the most common reason for hospitalization of these patients. Brain metastases are the most prevalent complication, affecting 20 to 40 percent of cancer patients and typically presenting as headache, altered mental status or focal weakness. Other common metastatic complications are epidural spinal cord compression and leptomeningeal metastases. Cord compression can be a medical emergency, and the rapid institution of high-dose corticosteroid therapy, radiation therapy or surgical decompression is often necessary to preserve neurologic function. Leptomeningeal metastases should be suspected when a patient presents with neurologic dysfunction in more than one site. Metabolic encephalopathy is the common nonmetastatic cause of altered mental status in cancer patients. Cerebrovascular complications such as stroke or hemorrhage can occur in a variety of tumor-related conditions, including direct invasion, coagulation disorders, chemotherapy side effects and nonbacterial thrombotic endocarditis. Radiation therapy is the most commonly employed palliative measure for metastases. Chemotherapy or surgical removal of tumors is used in selected patients.

Erythropoietin (EPO) is both hematopoietic and tissue protective, putatively through interaction with different receptors. We generated receptor subtype-selective ligands allowing the separation of EPO's bioactivities at the cellular level and in animals. Carbamylated EPO (CEPO) or certain EPO mutants did not bind to the classical EPO receptor (EPOR) and did not show any hematopoietic activity in human cell signaling assays or upon chronic dosing in different animal species. Nevertheless, CEPO and various nonhematopoietic mutants were cytoprotective in vitro and conferred neuroprotection against stroke, spinal cord compression, diabetic neuropathy, and experimental autoimmune encephalomyelitis at a potency and efficacy comparable to EPO.

Through a cohort of 93 neuroaids which has been diagnosed at Dakar in our Neurology Department, the authors evaluated the hospital prevalence of retrovirus, detected socio-demographic factors, related AIDS outline the mean neurological picture and try to correlate survival and neurological involvement of these patients. Among 1151 patients who got retroviral blood test, 93 were seropositive (8.1%). On these repartitions 36 were females (38.7%) and 57 males (61.3%). The age goes from 19 to 76 years old. 45 patients (48.4%) have been found positive for HIV-1 blood test, 21 patients (22.6%) for HIV-2 blood test, 11 patients (11.8%) for both HIV2, 11 patients (11.8%) for HTLV1, 3 patients (3.2%) for both HIV-1 and HTLV1, and 2 patients (2.2%) for both HIV-2 and HTLV1. In our study the transmission of AIDS occur mainly through heterosexual inter course and multiple parternship is a high risk group. The central nervous system deseases represented 68.8% of cases. The pathology were dominated by stroke, myelopathies, meningoencephalotis and spinal cord compression. The peripheral nervous system desease were found in 7.5% of cases. The peripheral facial paralysis occupied the first place in HIV infections of peripheral nervous system deseases (57.1% of cases). When neurological involvement set up the letality is higher for HIV-1 (57% of global letality) and for central system nervous involvement (76.2%).

Because of the apparition of new risk factors and numerous progresses in investigation methods, authors take stock of neurological diseases of patients admitted in Clinique Neurologique of Fann during the last ten years. The 8539 cases repartition is as followed: 4736 males and 3803 female. Their ages ranged between 3 and 80 years with 2130 deaths corresponding to 24.94%. Annual mean of admission is 853 +/- 42 cases. Aetiological data are: stroke (3910 cases 45.78% with 60.56% of death). The following is peripheral neuropathieswith 714 cases(8.61%) and the spinal cord compression with 692 cases (8.10%). Comparision of frequencies of different aetiologies with those of previous studies shows that the small capacity of the neurological department is a restricting factor for the entry frequencies of neurological patients; the principal pathologies got small variations from one decade to another. In the opposite, some aetiologies have disappeared (neurological syphilitis, trypanosomiasis, neurocyticercosis, cerebral mycosis). Some eatiologies remain unprecised (infectious diseases, peripheral neuropathies, degenerative diseases).

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder with variable expression. The complications are age specific. Neurologic complications include tumors of the peripheral nerves, nerve roots, and plexi; spinal cord compression; dural ectasias; learning disabilities; attention deficit; headaches; seizures; brain tumors; deafness; hydrocephalus; and stroke. High-intensity signals on brain magnetic resonance imaging are a frequent finding without known clinical significance. Most brain tumors are benign and asymptomatic, but malignant brain tumors occur. The major cause of death is malignancy, including brain tumors and malignant peripheral nerve sheath tumors. Management includes genetic counseling, regular eye examinations, and careful physical exams.
