A 46-year-old woman with non-Hodgkin's lymphoma presented with a new onset of seizures. A cranial CT was interpreted as normal. Eight months later, she presented with changed mental status and leg weakness, and a repeat CT scan showed multiple ring-enhancing lesions close to the left frontal sinus, with mass effect. A review of the previous CT scan showed a very small area of sinusitis as well as a small ring-enhancing lesion contiguous to it. A short course of intravenous steroids markedly relieved her symptoms, and a stereotactic biopsy confirmed Aspergillus fumigatus to be the cause of the infection. She was successfully treated with Amphotericin B. Central nervous system (CNS) aspergillosis is a potentially fatal disease. The therapeutic success in this case was related to a high index of suspicion at her second presentation. As the early signs of infection might be subtle and easily missed, patients at high risk for opportunistic infection should be studied carefully when new onset of CNS symptoms occur. Early initiation of therapy should improve the prognosis in such cases.

Pulmonary function was studied in ten preeclamptic women in labor (mean gestational age 38.1 +/- 0.9 weeks measured from the last menstrual period) receiving continuous intravenous (IV) infusions of magnesium sulfate. Baseline maximal inspiratory pressure, maximal expiratory pressure, functional vital capacity, and forced expiratory volume at 1 second were measured immediately before a 6-g IV loading dose of magnesium sulfate and 2 hours after the initiation of a continuous 2-g/hour infusion of magnesium sulfate. Serum magnesium levels were measured at the same time pulmonary function tests were performed. All values are reported as the mean +/- standard deviation. The maximal inspiratory pressure, an indicator of generalized respiratory muscle weakness, decreased from a baseline value of 26.2 +/- 7.7 to 19.4 +/- 6.3 cm H2O (P less than .05). The maximal expiratory pressure, an indicator of expiratory muscle strength, decreased from a baseline value of 30.6 +/- 9.2 to 25.2 +/- 7.1 cm H2O (P less than .005). The functional vital capacity decreased from a baseline value of 3.37 +/- 0.49 to 3.19 +/- 0.73 L, and the forced expiratory volume at 1 second decreased from a baseline value of 2.61 +/- 0.58 to 2.36 +/- 0.68 L at 2 hours (P less than .05). The mean serum magnesium level was 1.7 +/- 0.2 mg/dL before the administration of the IV loading dose and 4.51 +/- 0.67 mg/dL 2 hours after initiation of the continuous infusion. Our results demonstrate a significant decrease in pulmonary function tests in term preeclamptic patients receiving magnesium sulfate for seizure prophylaxis.(ABSTRACT TRUNCATED AT 250 WORDS)

We reviewed 63 cases of cytologically confirmed leptomeningeal metastases (LM). 31 (49%) had solid tumors 17 (27%) had leukemia and 15 (24%) had lymphoma. The most common presenting symptom was pain (76%) with radicular discomfort (58%), headache (32%), neck or back pain (17%). The predominant neurological signs were mental status abnormalities (49%), weakness (47%), seizures (14%). The mode of presentation varied with tumor type. Patients with leukemia (18%) and lymphoma (13%) tended to present frequently with LM without systemic involvement, or during periods of apparent remission (leukemia 35%, lymphoma 27%), while patients with solid tumors had established systemic metastases (90%) at time of presentation. Laboratory studies did not vary among the groups. 71% had positive cytology on the first lumbar puncture (LP) and only 8% required more than 2 LPs. The cell count was a poor predictor of positive cytology as 29% of LP's with positive cytology and 36% of all LP's had less than 4 cells/mm. We conclude that 1) LM presents with pain and seizures more frequently than has been previously recognized; 2) LM is frequently the mode of presentation in patients with leukemia and lymphoma and; 3) cytology is positive frequently in CSF specimens with normal cell counts and chemistries.

The knowledge and opinions of health professionals of Botucatu about the frequency and severity of thirteen symptoms and signs of diseases were studied with a view to comparing then with the opinions of Botucatu's urban population. Four hundred and thirty-five active health professionals (physicians, nurses, nurse aides, health workers (orderlies) and others were interviewed. Most of them were women, with ages ranging from 25 to 44. The health workers (orderlies) were the most numerous category. In general, the last five symptoms included in the form: bloody sputum, vaginal bleeding, breast lump, seizures and bloody urine, were considered less frequent and more serious as compared with the first eight symptoms: shortness of breath, fever, weakness, back pain (backache), chest pain, headache, cough and diarrhoea. Among the categories, the physicians differed from the other categories in less frequently attributing high scores to frequency and severity. The clinicians gave more value to these two factors than the surgeons for almost all symptoms. The comparison with the opinions of the laymen interviewed showed similar tendencies although the laymen regarded frequency and severity as more significant.

A variable combination of developmental delay, retinitis pigmentosa, dementia, seizures, ataxia, proximal neurogenic muscle weakness, and sensory neuropathy occurred in four members of a family and was maternally transmitted. There was no histochemical evidence of mitochondrial myopathy. Blood and muscle from the patients contained two populations of mitochondrial DNA, one of which had a previously unreported restriction site for AvaI. Sequence analysis showed that this was due to a point mutation at nucleotide 8993, resulting in an amino acid change from a highly conserved leucine to arginine in subunit 6 of mitochondrial H(+)-ATPase. There was some correlation between clinical severity and the amount of mutant mitochondrial DNA in the patients; this was present in only small quantities in the blood of healthy elderly relatives in the same maternal line.

A nine-year-old Chinese boy had suffered from recurrent episodes of adversive seizure for about a year, seizures which affected the left upper limb, with his head and eyes turning toward the left. An acute attack of left upper-limb weakness and central-type facial palsy occurred before his consultation. Cranial computed tomography (CT) revealed infarction of the right frontoparietal area, and increased density in the head of the left caudate nucleus. Cerebral angiographic study demonstrated a typical pattern of moyamoya disease with bilateral stenosis of the supraclinoid portion of internal carotid arteries. Encephaloduroarteriosynangiosis with encephalomyosynangiosis were performed twice, with resulting good patency of blood flow observed in the follow-up angiographic study.

Regional cerebral blood flow (rCBF) alterations, as determined by single photon emission computed tomography (SPECT) using technetium Tc 99m hexamethyl propylenamine oxime (Tc 99m-HM-PAO), were studied in 15 infants and children presenting with cerebrovascular disorders between the ages of 2 weeks and 16 years. The rCBF patterns were correlated with clinical presentation, electroencephalographic patterns, radiologic studies, including computed tomography and magnetic resonance imaging of the head, and cerebral angiography. All patients presented with motor weakness that was accompanied in some with dysphasia, defects in visual fields, obtundation, seizures, and high temperature. Perturbations of rCBF with Tc 99m-HMPAO SPECT brain scanning were detected in all patients investigated, with no adverse effects related to the radiotracer. All patients had a focal area of decreased rCBF, with adjacent hyperemia in 3 patients. In 7 patients, there was an rCBF decrease in a vascular distribution, mainly that of the middle cerebral artery, that correlated with the clinical findings and a focal electroencephalogram, as well as computed tomography and magnetic resonance imaging of the head. Impairment of rCBF was more extensive in 3 children, while early abnormal SPECT findings preceded abnormal computed tomographic findings in another 2 children. In 2 patients, Tc 99m-HMPAO SPECT was the only positive radiologic test to correlate with focal clinical and electroencephalographic abnormalities, in view of repeated normal computed tomographic scans. We conclude that Tc 99m-HMPAO SPECT brain scanning is a sensitive, complementary diagnostic measure in the early detection, localization, and estimation of rCBF alterations in pediatric cerebrovascular disease.

Patients with sickle cell disease are predisposed to infection caused by Streptococcus pneumoniae. However, there has been only one published case of bacteremic pneumococcal meningitis in an adult with sickle cell anemia. We report here the cases of six adults with sickle cell disease, pneumococcal sepsis, and meningitis. Five patients were male and one was female. Their ages ranged from 18 to 34 years (mean, 25.7 years). Five patients had the SS and one had the SC hemoglobin phenotype. Only one patient had received pneumococcal vaccine (14 valent). This vaccine did not protect against the pneumococcal serotype causing his infection. All patients had high fever (mean, 39.8 degrees C [103.7 degrees F]) on admission; five had generalized weakness and four had neck stiffness. Leukocyte counts were greater than 30,000/mm3 in all patients. Streptococcus pneumoniae was isolated from the blood and the cerebrospinal fluid in all patients. The cerebrospinal fluid showed pleocytosis in six patients, an elevated protein level in five, and hypoglycorrhachia in two. Complications included renal failure in four patients, disseminated intravascular coagulation in one, and seizures in another. Two patients died. Pneumococcal sepsis and meningitis are uncommon in adults with sickle cell disease, but they carry a high morbidity and mortality. Wider use of the new 23-valent polysaccharide vaccine in these patients is recommended.

It is well known that when Sturge-Weber syndrome manifests with seizures in early infancy, hemiparesis develops early, seizures become intractable, and motor weakness and mental retardation are progressive. In North America and Europe, early surgical intervention is recommended in such cases. However, neurosurgical management of Sturge-Weber syndrome has not been reported in Japan. The authors describe a 4-month-old boy with Sturge-Weber syndrome accompanied by intractable seizures who was successfully treated by a two-stage hemispherectomy. Two years postoperatively he remains free of seizures and is active, although his psychomotor development is moderately retarded. Surgical treatment of Sturge-Weber syndrome, including long-term results, is discussed in detail.

Cisplatin (DDP) is a chemotherapeutic agent that has shown efficacy against primary CNS malignancies. Intra-arterial (IA) administration of DDP to patients with brain tumors should produce higher peak levels of drug than intravenous (IV) administration of an identical dose and reduce systemic toxicity. Twelve patients with malignant glioma were entered into the study. All had failed irradiation, 11 had failed IA BCNU. Each patient received IA DDP, 58-100 mg/m2, into the internal carotid artery at four to six week intervals. One of 12 patients had a partial response of 6 months. The remaining 11 patients had progressive disease or severe complications. Toxicity included seizures in four patients, weakness and/or aphasia in four patients, coma in two patients, and visual deterioration in two patients. IA DDP has very limited efficacy in patients with malignant gliomas after failure of nitrosoureas and is associated with an unacceptable level of toxicity. IA DDP may be more effective when used as initial chemotherapy of malignant gliomas.
