The clinical spectrum of toxic effects and serum concentrations after ingestion of carbamazepine were studied in 82 pediatric patients. Serum carbamazepine level was related to the depth of coma (p less than 0.001), convulsions (p = 0.002), hypotension (p less than 0.001), and the requirement for mechanical ventilation (p less than 0.001). In 10 patients in deep coma with a Glasgow Coma Scale (GCS) of 3-4, the mean serum level was 213 mumol/L (range 143 to 343); seizures, ventilatory failure, or hypotension caused by myocardial failure and conduction defects were observed. In four of these, large doses of inotropic agents were required, one patient was treated with plasmapheresis, and two died--one of cardiac failure and one of aspiration pneumonitis. In 27 patients with moderate coma (GCS 5-8), the mean serum level of carbamazepine was 112 mumol/L (range 63 to 176); convulsions were observed in two patients in this group. In 45 patients whose conscious state was mildly depressed or normal (GCS 9-15), the mean serum level was 73 mumol/L (range 37 to 128); additional effects were drowsiness (80%), ataxia (53%), nystagmus (38%), vomiting (17%), and dystonia (7%). I conclude that patients with serum carbamazepine levels of approximately 100 mumol/L require close observation, whereas those with levels greater than 150 mumol/L may require intensive life support.

Five patients with documented recurrences of glioblastoma multiforme were given continuous infusions of methotrexate delivered intratumorally using implantable catheters and subcutaneous refillable pumps. A continuous infusion of methotrexate (1 mg/d) was begun with concomitant oral administration of folinic acid. The methotrexate dose was increased every 2 weeks to 3, 10, 30, and, ultimately, 75 mg/d in two patients. Samples of serum and ventricular cerebrospinal fluid (CSF) were obtained to determine the levels of methotrexate and total bioactive folates, and brain tissue was obtained from two patients for determination of methotrexate concentration. The patients survived from 7 to 49 weeks after the implantation of the infusion device. Neither the clinical examination nor sequential radiological studies gave clear evidence of reduction in tumor size. Pneumonia developed in one patient, and mild hepatitis and increased seizure frequency in another. Methotrexate was stable in the delivery system over 12 days, and ventricular CSF reached steady-state levels by 5 days. Steady-state ventricular CSF levels of methotrexate were higher than serum levels in some patients, while the reverse was true in others. Levels of total bioactive folates in the CSF did not increase above the normal range. Methotrexate concentrations were highest at the center of the tumor, but measurable amounts of methotrexate were detectable in all areas of the brain. At autopsy in four patients, variable liquefactive necrosis of the brain tumors was seen, and viable tumor was found at the periphery of the tumor bed. These preliminary results suggest that it is technically feasible to infuse methotrexate into brain tumor cavities, and show that little central nervous system or systemic toxicity was encountered in five patients. Better delineation of the safety and efficacy of this therapeutic approach will require further clinical trials.

Convulsive conditions account for 69.8% out of the total number of patients admitted to the department of intensive care of the children's neurological hospital. In 25.3% (348 children) they first developed in the presence of somatic pathology of the infectious inflammatory genesis in children with perinatal brain injury. Acute somatic pathology (acute respiratory diseases, pneumonia, intestinal infections) dominated (n = 318). In all the children, convulsive seizures occurred in hyperthermia largely in early childhood. Apparently, in the majority of cases, perinatal injury alone was insufficient to precipitate seizures. However, the combined perinatal brain injury and an infectious disease form favourable conditions for the appearance of convulsive conditions in children. Therefore, to prevent them, of importance is the prophylaxis of both perinatal pathology and infectious diseases. The patients with convulsive conditions should be given combined treatment including anticonvulsants, antiinflammatory, antibacterial, detoxication and other drugs.

CAPD peritonitis is most commonly due to gram positive infection. Gram negative bacillary infection is less frequent but is often seen in hospitalized patients or in those on antibiotics. Weeksella virosa (formerly known as Flavobacterium II F) has been isolated from the vaginal secretions and urine of normal women. As gram negative colonization typically proceeds from the perineal region, Weeksella virosa peritonitis might be expected in women at risk for gram negative peritonitis. A 33-year-old woman on CAPD developed multiply resistant Weeksella virosa peritonitis after prior hospitalization for pericarditis and antibiotic treatment for pneumonia. Cultures became negative and cell counts returned to normal during treatment with intravenous imipenem/cilastin. Curative treatment was completed with intraperitoneal imipenem/cilastin and oral ampicillin. Treatment was well tolerated despite theoretical concerns about the risk of seizures in patients with severe renal insufficiency not on hemodialysis.

A 60-year-old man had been administered diphenylhydantoin (DPH) for prevention of convulsive seizures following clipping of an aneurysm of the middle cerebral artery. About one month after the commencement of DPH administration, he developed cough and low grade fever. He was treated with various antibiotics, but his condition increasingly worsened. Chest X-ray film revealed bilateral interstitial processes throughout the entire lung fields. Transbronchial lung biopsy was performed and the obtained specimen showed histological findings compatible with drug-induced pneumonitis. Administration of DPH was stopped immediately and 50 mg/day of prednisolone was started. The patient's condition rapidly improved, and the abnormal shadows on chest X-ray film gradually diminished. The lymphocyte stimulation test by DPH was positive with a stimulation index of 282%.

The case of a healthy five-year-old, thirty-six pound female patient scheduled for multiple extractions is reported. The child received a total dose of 270 mg of mepivacaine, instead of the correct dose of 72 mg, which resulted in multiple seizures, hospital admission, pneumonia, and death caused by anoxic brain injury secondary to cardiopulmonary arrest following the overdose.

A prognostic score was derived from a prospective study of 120 consecutive patients with cerebrovascular accident. Multivariate analysis was used to compare the presenting clinical features of 106 (88%) of these patients with their immediate outcome (survival or death). Similar analysis was also used to compare features on CT scan with immediate outcome in 45 patients. The immediate prognostic features included old age, history of previous stroke, mental obtundation at the onset, persistent altered consciousness greater than or equal to first 48 hours, altered consciousness appearing in the first 24-72 hours, complete hemiplegia, seizures, aspiration pneumonitis, and multiple/massive lesions and gross mass effect on CT scan. The prognostic score derived from discriminant function using CT scan variables was less accurate than that formulated from only clinical variables. In the latter (using clinical variables) a prognostic score of 46 or less suggested a 50% chance of recovery, scores of 47 or more a 50% chance of death, while scores of 12 or less and 63 or more suggested a 99% likelihood of survival and death respectively.

The authors retrospectively reviewed the charts of 31 alcoholic patients admitted with fever without a defined source. In our population 58% of patients were subsequently found to have an infectious cause for their fever. Pneumonia was the most common infection, but occult urinary tract infections were seen surprisingly often. Noninfectious but serious disorders, such as delirium tremens, prolonged postictal state, and subarachnoid hemorrhage, were also common. Infectious and noninfectious causes commonly coexisted. The most common noninfectious cause was alcohol withdrawal, with or without seizures. The authors believe that indigent, malnourished, chronic alcoholics with fever for which a source cannot be readily identified, should usually be admitted to the hospital for observation and to await culture results.

A study of 1000 consecutive autopsies of individuals dying of natural disease was conducted. Cardiovascular disease was responsible for 60.9% of all deaths with coronary artery disease--not only the main cause of cardiovascular death but also the main cause of all natural deaths--accounting for 45.1% of such cases. Diseases of the central nervous and respiratory systems accounted for 8.7 and 8.6%, respectively, of the natural deaths. Seizure disorders and pneumonia were the main causes of death in these organ systems. There were 124 deaths of children less than one year in age, 91 of which were due to sudden infant death syndrome (SIDS). All of the SIDS deaths were in children less than 10 months old.

Features of typhoid fever were correlated with age and gender through a review of the charts of 552 hospitalized culture-positive patients with diarrhea in Bangladesh. Seizures occurred more frequently in children from birth through 10 years of age (5%-11%) and pneumonia more frequently in children from birth through 5 years of age (8%-15%) than in older age groups (P less than .05), whereas intestinal perforation occurred more frequently in patients greater than or equal to 11 years of age (5%-25%) than in younger age groups (P less than .005). Compared with older age groups, children from birth through 10 years of age were more anemic, those from birth through 5 years of age had a higher mean white blood cell count, and those from birth through 1 year of age had a lower mean blood carbon dioxide content (all P less than .05). Female patients were more severely anemic than male patients (P less than .05). The case-fatality rate was 4.3% overall, with the highest rates for children from birth through 1 year of age (11%) and adults greater than or equal to 31 years of age (10%). Female patients had a higher case-fatality rate (6%) than male patients (3%), although the difference was not significant (P greater than .05). Death was independently associated with seizures, intestinal perforation, pneumonia, and delirium or coma. These results indicated that the patients with typhoid fever who were at highest risk of complications and death were children from birth through 1 year of age and adults greater than or equal to 31 years of age.
