Of 44 children with hemolytic-uremic syndrome seen at Milwaukee Children's Hospital, 15 (34%) had neurological involvement. This group contained 8 boys and 7 girls, with a mean age of 3 1/4 years. Twelve patients had seizure within 48 hours of admission. Seizures were associated with hypertension, fever, hyponatremia, or hypocalcemia. Other neurological symptoms included altered consciousness, behavioral changes, diplopia, and dizziness. Hemiparesis (4 patients), eye involvement (7 patients), decerebrate posturing (2 patients), and ataxia (1 patient) were present on physical examination. Cerebrospinal fluid examination showed increased protein in 4 of 11 patients. Electroencephalograms were abnormal in all 9 patients tested. Computed tomographic and radionuclide scans showed evidence of vascular abnormalities in 4 of the 14 patients studied. Complete neurological recovery occurred in only 6 of the 15 children, while the remaining 6 demonstrated residual hemiparesis, seizures, and cortical visual defect. In those children with neurological involvement, there was a higher incidence of residual hypertension (49% versus 11%), chronic renal damage (40% versus 3.5%), and death (28% versus 0%), suggesting that central nervous system involvement indicates severe hemolytic-uremic syndrome.

Angiographically occult arteriovenous malformations not associated with clinically recognizable intracranial hemorrhage appear to be rare. We are reporting three cases of histologically proven arteriovenous malformations of the brain that were angiographically occult. These cases presented with seizures or attacks of dizziness, and were detected by computed tomography scan, radionuclide scan, or both. The preoperative diagnosis was granuloma in the first case and meningioma in the other two. After surgical exploration, biopsy revealed an arteriovenous malformation in each case. A review of 47 cases in the literature is tabulated and etiologies of the angiographically occult arteriovenous malformations are discussed. The routine use of computed tomography scan and timely, appropriate surgical intervention with the operating microscope for the removal of these deeply situated lesions is necessary for the diagnosis and therapy.

We conducted a pilot study of fluzinamide in 15 adults with refractory partial seizures. After a baseline period, fluzinamide was added to the existing regimen of phenytoin and carbamazepine and increased to maximum tolerated dose. Common side effects included dizziness, diplopia, ataxia, headache, nausea, and rash, resulting in patient withdrawal in six cases. Seizures became less frequent in four of the nine patients who completed the 8-week trial.

A total of 202 nonepileptic patients (120 males and 82 females) who exhibited spike abnormalities at least twice in their EEG examinations were studied. The incidence of spike abnormalities among nonepileptic patients was 8.1% (847/10,473). The majority (90%) were under age 19. Headache, dizziness and vomiting, and abdominal pain were more frequently observed compared with controls. Mild paroxysmal EEG abnormalities such as diffuse irregular slow wave bursts with spike (27%), positive spikes (25%) or small spike (8.4%) were commonly detected. In three patients who developed epileptic seizures during the follow-up period, more specific EEG abnormalities were often exhibited. Other factors like the age at onset before 9, characteristic clinical symptoms or a positive family history of seizures were confirmed to be necessary for the manifestation of clinical seizures.

Twelve parallel, open, uncontrolled therapeutic studies on 3-fluoro-6-(4-methyl-piperazinyl)- 11H -dibenz[b,e]azepine ( fluperlapine , NB-106 689) were performed as a multicenter trial using standardized protocol/case report forms and inclusion and global assessment criteria. 66% of 104 medium to severe acute or relapsed schizophrenic patients showed a very good or good overall benefit (responder rate 80%) with 200-400 mg fluperlapine daily, median 300; 20-1200 mg; 6 weeks. Ratings ( FSCL -NL = (Fischer Symptom Check List Neuroleptics, BPRS = Brief Psychiatric Rating Scale, FSUCL = Fischer Somatic Symptoms and Untoward Effects Check List) showed a quick onset of action (25% improvement in 5 days) and a very good improvement of all important and secondary single symptoms or symptom groups. FSCL -NL and BPRS were highly correlated (R = 0.87). Tolerability was very good or good in 88% of patients (very good in 65%, poor or bad in 12%), mild to moderate fatigue being the most prominent untoward effect (means 25% of patients, max. 31 per control) followed by dizziness, tremor, dry mouth (10%). No drug-induced Parkinsonism was seen. No recurrent or relevant abnormalities in relation to fluperlapine were observed in safety data (circulation, blood, kidney or liver function). Several times paroxysmal dysrhythmias/sharp waves were seen in the EEG, and in our studies 2 patients experienced epileptiform seizures of short duration after overdosage. In one patient showing a granulocytopenia before starting fluperlapine , an agranulocytosis was seen, which normalized quickly after stopping fluperlapine .

In 3 decades 1550 patients showed 6/sec spike and wave complexes; 839 were chosen for computer-analyzed electroclinical correlations. Control groups (each 500) included patients (1) randomly selected from EEG files, (2) with normal EEGs, (3) with only slow wave abnormalities, and (4) with only spike abnormalities. In the experimental group more females and Caucasians were found with peak age distribution at 11--15 years. The major symptoms were seizures (53%), neurovegetative (51%) and psychological complaints (24%), all significantly different from control groups, except for seizures in control group 4. Seizures were mainly generalized motor attacks, neurovegetative symptoms included headaches, dizziness and blackouts and psychological symptoms were mainly behavior disorders. As a presumed etiology head injury was noted in over 25% with this complex, which was maximal either on the anterior or occipital areas. Further computer analysis shows that two extreme forms can be identified: (1) the WHAM form, seen mainly in waking records, high amplitude, anterior location, more males, and (2) the FOLD form, seen mainly in females, occipital location, low amplitude, in drowsy states. The WHAM form appears primarily in patients with seizures, and the FOLD form in patients with neurovegetative and psychological complaints.

Beta-blockers are increasingly often used with suicidal intent, but are also sometimes swallowed accidentally by small children. Beta-blockers available in the Federal Republic of Germany differ in their pharmacodynamics and pharmacokinetics. After analysing 49 cases of intoxication, no certain relationship was found between the different substances and specific symptoms. Cardiovascular signs such as sinus bradycardia, arrhythmia, hypotension (30 cases), as well as dizziness and drowziness (17) were the most frequent ones. Loss of consciousness and hallucination (13), as well as seizures (3), also occurred frequently. Hypoglycaemia or symptoms due to it (12) were noted especially in young children. In addition to primary removal of the drug, repeated administration of charcoal and sodium sulphate are recommended with most of the drugs for interrupting the enterohepatic circulation. Administration of atropine for bradycardia and hypotension was usually not effective. Dopamine is recommended; glucagon for definite signs of shock. Haemodialysis is indicated only in exceptional instances and is effective for only a few of the drugs. Forced diuresis should not be practised.

Six cases of oral intoxication with lindane-solvent mixtures are reviewed. The ingested doses of lindane (mean dosage 120 mg/kg +/- 86 mg/kg) and benzene (mean dosage 366 mg/kg +/- 93 mg/kg) exceeded the toxic level. Symptoms (vomiting, dizziness and hyperreflexia) occurred within 30 min and all patients had epileptiform seizures. Two patients suffered from pulmonary edema and one of them had a severe rhabdomyolysis. Diazepam was sufficient to control convulsions in five cases. Gastric lavage was performed in five patients and activated charcoal, liquid paraffin with saline cathartic, and cholestyramine were used as adsorbents. Recovery was complete in all patients.

In a previous study it has been shown that sodium diphenyl hydantoinate is effective in preventing electrically induced convulsive seizures in cats. The drug is relatively nontoxic and well tolerated by the usual laboratory animals. A clinical trial of sodium diphenyl hydantoinate was made in 200 patients with frequent convulsive seizures which had not been relieved by the previous modes of therapy. In 142 such patients who have received the treatment for periods varying from two to eleven months, grand mal attacks were relieved in 58 per cent and greatly decreased in frequency in an additional 27 per cent; petit mal attacks were relieved in 35 per cent and greatly decreased in frequency in an additional 49 per cent, and psychic equivalent attacks were relieved in 67 per cent and greatly decreased in frequency in 33 per cent. There were no fatalities. A toxic dermatitis occurred in ten patients (5 per cent), nonthrombocytopenic purpura in one patient and minor (in many instances, transient) toxic reactions, tremors, ataxia, dizziness and the like in approximately 15 per cent.

Within 20 months 145 ascending thoracocervical myelographies and 155 lumbar myelographies with the nonionic water-soluble contrast medium iopamidol were performed. The iodine concentration given was 250 mg I/ml or 200 mg I/ml respectively. The total iodine never exceeded 2.5 g (8-10 ml). Image quality was assessed in terms of diagnostic value having experience of more than 1,000 myelographies using metrizamide. Picture quality was similar to metrizamide of equal iodine concentration. In 35 patients electroencephalography (EEG) was recorded before and after myelography with iopamidol 250. No changes that could be referred to the contrast medium were seen. There were no adverse reactions to lumbar myelography other than those following the lumbar puncture. In thoracocervical myelography mild and transient side effects occurred in 41 (28.3%). The most common were headache (41 cases), nausea (12), radicular pain (10), and dizziness (five). General seizures and psychopathologic symptoms were not observed.
