Multicenter noncomparative trials of intramuscular administration of imipenem/cilastatin for the treatment of a variety of infections requiring multiple-dose therapy are reviewed. Fourteen centers in the United States and 18 centers elsewhere participated in these studies. A total of 686 patients (461 evaluable) were treated worldwide. The severity of the infection was rated as moderate in 58.9%, mild in 37.2% and severe in 0.6%. The most common sites of infection were the skin and soft tissue (36.2%) and intra-abdominal (17.6%). Polymicrobial infections were relatively common (27%). Dosing regimens in evaluable patients were 500 mg every 12 h (45.1%), 750 mg every 12 h (36.2%) and 500 mg every 8 h (18.6%). The overall clinical outcome was favorable (clinical cure or improvement) for 95% or more of the evaluable patients with the various body system infections, except in gynecologic infections where 89% of the evaluable patients had a favorable outcome and for sepsis where the favorable outcome was 76%. Where data were available for analysis (skin and soft tissue infections) there was no difference in favorable clinical outcome among patients with moderate infection treated with 1.0 g/day (95% favorable) compared with 1.5 g/day (94% favorable). The overall bacteriologic eradication rate was 91%. Clinical adverse effects were similar in type but less common in frequency than those noted in other studies with the intravenous formulation, with nausea, vomiting and diarrhea being most common; no instances of seizures or confusion were observed. The laboratory adverse effects were similar to those seen in other studies with the intravenous formulation, with increased liver enzyme values the most common. The intramuscular injection was well tolerated in 87% of the patients and moderately well tolerated in 6.6%. The efficacy and low incidence of side effects of the intramuscular formulation of imipenem/cilastatin are significant advantages in the cost-effective treatment of infections.

A long-term follow-up study of 42 patients with West syndrome treated with high doses of sodium valproate is presented. Control of the hypsarrhythmic EEG pattern was achieved after two weeks for over three-quarters of the patients with sodium valproate doses of 100 to 300mg/kg/day. Recurrence of hypsarrhythmia was observed most often in patients treated with doses lower than 200mg/kg/day. Other types of seizures appeared in half of the patients followed beyond two years of age. Monotherapy throughout follow-up was possible for 30 patients. Autism occurred in only one infant, and 12 achieved normal mental status. The most common side-effects were asymptomatic thrombocytopenia, vomiting and mild somnolence. Hepatic enzymes were not altered.

Deficiency of 3-hydroxy-3-methylglutaryl-CoA lyase has been studied in 11 Saudi infants. The diagnosis was established by the measurement of enzyme activity in lymphocytes, in fibroblasts and, in seven patients, by the gas chromatography/mass spectrometer pattern of excreted organic acids in the urine. In seven infants the disease caused a devastating acidotic attack within the first day of life, while in two the crisis occurred by the third day of life. In two infants from one family the disease appeared later in infancy. The clinical presentation of an acidotic attack is lethargy, hyperpnoea, tachypnoea and seizures, either at birth (two infants), following first feeding (in five infants), or following vomiting or refusal of food in later infancy. The acidotic attacks recurred later in life following minor illness or refusal to eat. The acidosis of this enzyme deficiency progresses rapidly, leading to cardiopulmonary arrest and death within hours of onset unless treated promptly. In four surviving infants diagnosed and treated early, development is normal. Magnetic resonance and computerized tomography brain scans in these infants, however, show white matter lesions and mild atrophy.

An outbreak of food poisoning resulting in 13 deaths in children occurred in Malaysia during the Chinese Festival of the Nine-Emperor Gods in 1988. The offending food was a Chinese noodle called 'Loh See Fun' (LSF). The source was traced to a factory where a banned food preservative was added to make the LSF. The food poisoning was attributable to aflatoxins and boric acid. The clinical features included vomiting, pyrexia, diarrhoea, abdominal pain, anorexia, giddiness, seizures, and eventual coma. Initially, many presented with a Reye-like syndrome. Eleven post-mortem examinations were performed. The pathological findings included extensive coagulative necrosis of the liver with proliferative 'ductal/ductular metaplasia of the hepatocytes'. Giant cell formation, central vein sclerosis, bile stasis, and steatosis were also noted. There was presence of acute tubular necrosis, superficial upper gastrointestinal erosions, and ensuing encephalopathy. The eventual cause of death is acute hepatic and renal failure.

Intravenous fluorescein angiography is a commonly performed and extraordinarily valuable diagnostic procedure. The frequency of adverse reactions after angiography has varied considerably in previous reports. In a prospective study of 2789 angiographic procedures in 2025 patients, the authors found that the percentage of adverse reactions depended strongly on the patient's angiographic history. Overall, adverse reactions followed 4.8% of the angiographic procedures. These reactions included nausea (2.9%), vomiting (1.2%), flushing/itching/hives (0.5%), and other reactions (dyspnea, syncope, excessive sneezing) (0.2%). No cases of anaphylaxis, myocardial infarction, pulmonary edema, or seizures occurred. The percentage of reactions was 1.8% for patients who had had previous angiography without ever having had an adverse reaction. In contrast, the percentage of reactions was 48.6% for patients who had had an adverse reaction to angiography previously.

We report a 14-year-old boy with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS) who presented repeated episodes of abdominal pain and vomiting since the age of 8 years. In addition, he developed strokelike episodes with myoclonic seizures and transient hemiplegia on three occasions. At the age of 14-1/12-years, he also developed epilepsia partialis continua persisting for 10 days, which was associated with myoclonic seizures synchronized with spike discharges at the right central area. Laboratory examination disclosed increased levels of lactate and pyruvate in serum and CSF and low density areas in the bilateral temporal regions on CT scan. Muscle biopsy showed scattered ragged-red fibers. The enzyme activities (pyruvate dehydrogenase complex, pyruvate carboxylase, phosphoenol pyruvate carboxykinase, and cytochrome c oxidase) and the rates of decarboxylation of [3-14C]pyruvate in cultured skin fibroblasts were within normal ranges.

Amantadine hydrochloride has been shown in several open studies to benefit children with refractory generalized epilepsy. We used amantadine as adjunctive therapy in 10 adolescents and adults with generalized tonic-clonic, myoclonic, or absence seizures refractory to therapeutic levels of valproate, carbamazepine, phenytoin, and benzodiazepines. Seven patients were men and 3 were women aged 18-29 years, and 8 of 10 patients were mentally retarded. All patients had generalized epileptiform paroxysms on EEG, with generalized or absence seizure recorded in 9. Five patients had both absence and tonic-clonic seizures, and 2 had all three seizure types. Amantadine was added to the existing regimens in weekly increments to 400 mg/day. Two patients had greater than 90 per cent seizure reduction, both with vomiting and somnolence. Two patients had seizure reduction between 50 and 90 per cent, 1 with anorexia and sleepiness. Three patients had no change in seizures, and 3 had worse tonic-clonic seizures. Amantadine may have some antiepileptic efficacy of unknown mechanism, but it may worsen generalized tonic-clonic seizures and is likely to be of limited value in adults.

Continuous subcutaneous infusions offer a safe, simple, effective alternative to intravenous or intramuscular injections when oral medications cannot be used. They are extremely useful for cancer patients suffering from pain, vomiting, seizures, and other symptoms. Hydromorphone or morphine may be combined with metoclopramide, methotrimeprazine, or haloperidol (in D5W only), in the same pump to control both pain and nausea. Seizures can be controlled by subcutaneous infusion of phenobarbital or midazolam. If proper doses are prescribed and skin irritation is watched for, they can be used safely in the patient's home.

In Canada in late 1987 there was an outbreak of an acute illness characterized by gastrointestinal symptoms and unusual neurologic abnormalities among persons who had eaten cultivated mussels. Health departments in Canada solicited reports of this newly recognized illness. A case was defined as the occurrence of gastrointestinal symptoms within 24 hours or of neurologic symptoms within 48 hours of the ingestion of mussels. From the more than 250 reports received, 107 patients met the case definition. The most common symptoms were vomiting (in 76 percent of the patients), abdominal cramps (50 percent), diarrhea (42 percent), headache, often described as incapacitating (43 percent), and loss of short-term memory (25 percent). Nineteen patients were hospitalized, of whom 12 required intensive care because of seizures, coma, profuse respiratory secretions, or unstable blood pressure. Male sex and increasing age were associated independently with the risks of hospitalization and memory loss. Three patients died. Mussels associated with this illness were traced to cultivation beds in three river estuaries on the eastern coast of Prince Edward Island. Domoic acid, which can act as an excitatory neurotransmitter, was identified in mussels left uneaten by the patients and in mussels sampled from these estuaries. The source of the domoic acid appears to have been a form of marine vegetation, Nitzschia pungens, also identified in these waters in late 1987. The contaminated mussels from Prince Edward Island were removed from the market, and no new cases have occurred since December 1987. We conclude that the cause of this outbreak of a novel and severe intoxication was the ingestion of mussels contaminated by domoic acid, a potent excitatory neurotransmitter.

During 1988, an endemic outbreak of aseptic meningitis was noted in the Kaohsiung area. Throughout the year, a total of 89 cases were identified by cerebrospinal fluid (CSF) examination at the Pediatric Department of Kaohsiung Medical College. The peak incidence was from June to October. Scattered cases still occurred during November and December. The male to female ratio was 1.7:1 and the age distribution ranged from 1 month to 15 years old. Two peaks of age distribution were observed; one in infancy and the other in the 4-7 year old age group. Most of them exhibited fever (94.4%), headache (68.9%), and vomiting (68.5%). Other associated symptoms and signs included neck stiffness, sore throat, cough, Brudzinski's sign, abdominal pain, seizure, dizziness, rhinorrhea, diarrhea, Kernig's sign, skin rash, hyperemic conjunctiva, apnea, and oral ulcers. Most of them had CSF white blood cell (WBC) counts less than 1000/mm3, normal or mild elevated protein, and normal CSF/plasma sugar ratio. Three patients were found to have a virus in their CSF without pleocytosis. Virus isolations from CSF throat swabs and/or rectal swabs were performed in 65 patients, half of them (35/65, 53.8%) had positive results including echovirus type 9 (sixteen), echovirus type 30 (eighteen), and adenovirus type 3 (one). Echovirus type 9 was predominant during July and August whereas echovirus type 30 became predominant after September. All patients recovered spontaneously without any sequelae.
