In a double-blind randomized trial, imipenem/cilastatin (I/C; 500 mg every 6 hours) and ampicillin/sulbactam (A/S; 3 g every 6 hours) were compared in regard to their efficacy for initial empirical and definitive parenteral treatment of limb-threatening pedal infection in diabetic patients. The major endpoints of treatment were cure (resolution of soft-tissue infection), failure (inadequate improvement, necessitating a change in antibiotic therapy), and eradication (clearance of all pathogens from the wound and any bone cultures). Patients in the two treatment groups were similar in regard to the severity of diabetes; presence of neuropathy and peripheral vascular disease; site and severity of infection; pathogen isolated; and frequency of osteomyelitis (associated with 68% of the 48 A/S-treated infections and 56% of the 48 I/C-treated infections). After 5 days of empirical treatment, improvement was noted in 94% of the A/S and 98% of the I/C recipients. At the end of definitive treatment (days' duration [mean +/- SD]: 13 +/- 6.5 [A/S], 14.8 +/- 8.6 [I/C]), outcomes were similar: cure, 81% (A/S) vs. 85% (I/C); failure, 17% (A/S) vs. 13% (I/C); and eradication, 67% (A/S) vs. 75% (I/C). Treatment failures were associated with the presence of antibiotic-resistant pathogens and possible nosocomial acquisition of infections. The number of adverse events among patients in the two treatment groups was similar: 7 in the A/S group (4 had diarrhea and 3 had rash) and 9 in the I/C group (5 had diarrhea, 2 had severe nausea, 1 had rash, and 1 had seizure). Efficacy of A/S and I/C is similar for initial empirical and definitive treatment of limb-threatening pedal infection in patients with diabetes.

Over a 3-year period, 15 patients with severe hyponatremia were referred to our emergency room from a nearby psychiatric institution. This article reports on 36 episodes of symptomatic hyponatremia in those 15 patients. All but two of the patients were receiving antipsychotic medications; one patient was taking a nonsteroidal anti-inflammatory drug, and one patient was taking an oral hypoglycemic agent. Thirteen patients were chronic schizophrenics, one had a bipolar depressive disorder with psychotic features, and one patient had no psychiatric disorder. Patients presented with seizures, change in mental status, and vegetative symptoms (nausea, vomiting, and diarrhea) associated with hyponatremia and water intoxication. Exacerbation of the patients' underlying illness, psychogenic polydipsia, compulsive smoking, alcoholic cirrhosis, drug abuse, and neuroleptic and other medications are thought to be the major causes of acute hyponatremia in these patients.

Even without electrolyte imbalance, dehydration and fever, seizures are found occasionally in the cases of mild diarrhea. Such patients have shown favorable outcome during long-term follow-up. Twenty cases (10 boys and 10 girls) of benign seizure with mild diarrhea have been diagnosed at the Pediatric Department of Cathay General Hospital from January 1987 to March 1991. Ages-of-onset ranged from 3 months to 43 months (mean 19 months). Most cases were found between December and March (16 cases, 80%). Most seizure episodes were from 2 to 5 times (10 cases, 50%); the durations of seizures were mostly within a 5-minute period (16 cases, 80%). All seizures were generalized and symmetric, including tonic-clonic (13 cases, 65%), tonic (5 cases, 25%), and clonic (2 cases, 10%). Six out of 11 cases (54.5%) showed Rotazyme (Latex agglutination) positive. After six month to four year follow up, no patient had suffered any type of epilepsy, and psychomotor development was normal in all. Further discussion of clinical features is provided.

Eighty-seven cats with histologically confirmed malignant tumors were used in a prospective study to determine the toxicity of mitoxantrone, a dihydroxyquinone derivative of anthracene, which was administered at 21-day intervals at dosages ranging from 2.5 to 6.5 mg/m2 of body surface, IV. Eleven of these cats were treated concurrently with radiation but were evaluated separately. Each cat was evaluated for signs of toxicosis for 3 weeks after each dose was administered or until the cat developed progressive disease, or until the cat's quality of life diminished to an unacceptable level as determined by the owner or attending veterinarian. Although the primary purpose of this study was to determine a clinically useful dosage and to characterize the toxicoses associated with mitoxantrone administration, each cat was monitored for response to treatment. Forty-nine cats had been refractory to 1 or more treatment modalities prior to inclusion in this study. The most common signs of toxicosis after treatment with mitoxantrone were vomiting, anorexia, diarrhea, lethargy, sepsis secondary to myelosuppression, and seizures. Two cats died of complications that may have been attributed to mitoxantrone: 1 of cardiomyopathy and the other of pulmonary edema of an undetermined cause. Older cats were more likely to develop signs of toxicosis after the third or fourth mitoxantrone treatment than younger cats (P < or = 0.05). Cats with signs of toxicosis during the 21-day interval after administration of the first dose of mitoxantrone were significantly (P < or = 0.05) more likely to develop signs of toxicosis during the 21-day interval between the second and third doses of mitoxantrone.(ABSTRACT TRUNCATED AT 250 WORDS)

Munchausen syndrome by proxy is an increasingly reported insidious disorder in which illness in a child is fabricated and/or induced by the parent. Over a 5-year period at North Carolina Children's Hospital 10 such children were identified after having presented to the Pediatric Surgical Service. In reviewing this experience, we have identified two patterns of presentation. Apnea, seizures, and cyanosis comprised the pattern most frequently seen in infants. A history of persistent diarrhea and vomiting, although seen in two infants, was the more common pattern in older children. As they got older, four of the infants subsequently were noted to have the childhood pattern of symptoms. The mother was the perpetrator in all cases with the child's illnesses being induced by a number of different mechanisms. The most useful diagnostic tool proved to be isolation of the child from the parent. Resolution of symptoms in parental absence was a consistent finding especially in fabrication cases and was the key to diagnosis. Video telemetry confirmed the diagnosis in two infants and screens for toxins were diagnostic in three others. Awareness of patterns of presentation and parental behavior is critical to establishing an early diagnosis and avoiding needless diagnostic and operative procedures.

Even a single honeybee sting can lead to anaphylaxis in a susceptible person, but severe reactions can result from multiple stings, particularly if stings are from the fast-spreading Africanized honeybees, sometimes called "killer" bees. Signs and symptoms of multiple stings may include urticaria, nausea, vomiting, diarrhea, hypotension, confusion, seizures, and renal failure. Treatment is entirely supportive and requires special attention to airway patency, blood pressure, and renal function. Patients with more than 50 stings are at a higher risk of toxicity. Stingers should be removed by scraping gently to prevent further venom injection. Smoke or aerosolized deet (diethyl-toluamide) may thwart attacking bees, but avoidance is the best line of defense.

Clinical signs that included lethargy, inappetence, diarrhea, and vomiting and that progressed to seizures were observed in 40 feeder pigs that were approximately 70 days old. The pigs were fed ground red wheat and whole milk and were housed in a barn that did not allow exposure to direct sunlight. Analysis of samples of feed obtained from the farm indicated inadequate quantities of calcium and phosphorus as well as a low ratio of these 2 nutrients. Serum and tissue concentrations of vitamin A were less than normal. Low serum calcium concentrations, high serum phosphorus concentrations, and high alkaline phosphatase and creatine kinase activities were compatible with low vitamin D concentrations.

Data from 3125 patients (3220 patient exposures) treated with meropenem were compared with those from 2886 patients (2960 patient exposures) treated with a variety of comparator agents including cephalosporins (alone or in combination with aminoglycosides or an anti-anaerobe agent) and imipenem/cilastatin. Patients treated included those with bacterial infections of the lower respiratory tract, urinary tract and skin and soft tissues, abdominal, obstetric and gynaecological infections, meningitis, febrile episodes in neutropenic patients and paediatric patients with infections. In three studies, meropenem was administered intramuscularly; in the remainder, meropenem was given by 15-30 min iv infusion or by bolus injection over approximately 5 min. The usual dosages were 500 mg or 1 g 8 hourly in adults and 10 or 20 mg/kg 8 hourly in children. In bacterial meningitis, the meropenem dosage in adults was 2 g 8 hourly and 40 mg/kg 8 hourly in children. The overall pattern and frequency of adverse events with meropenem were similar to those of the other beta-lactam antibiotics with which it was compared. The most frequently reported adverse events were diarrhoea, rash, nausea and vomiting, thrombocytosis, eosinophilia and changes in hepatic biochemistry. Abnormal laboratory tests occurred with similar frequencies between meropenem and the comparator agents. The safety profile of meropenem was similar in adults and children, and the presence of renal impairment did not alter the safety profile of meropenem. Experience in clinical studies in 3220 patient exposures has revealed no unusual or unexpected toxicity. The possibility of administration by either iv infusion or bolus injection with a low incidence of nausea and vomiting also provides flexibility in the clinical management of patients. Moreover, the low incidence of reported seizures and good tolerability at high doses, make meropenem particularly useful for the treatment of meningitis and other indications which carry a risk of seizures, or in the treatment of serious infections where high doses of antibiotics are frequently indicated.

From May 1984 to April 1995, a total of 16 patients (12 females, 4 males) with cerebral venous thrombosis, diagnosed by computed tomography (CT), conventional cerebral angiography, magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA), were reviewed retrospectively. The age ranged from 1 month to 16 years of age (average: 2.5 years) with 8 below 1 year of age. The presenting symptoms for infants were mental change (75%) and seizure (100%), mainly generalized (63%) in character. Associated illness was mainly closed head injury, diarrhea or dehydration. All infants had mild to severe motor handicap in a 1 to 10 year follow-up. In contrast, older children frequently presented with headache (37%) or consciousness change (50%), and were more frequently associated with sepsis or local infections. Four (50%) of them recovered completely, but two died and two were finally in a vegetative state. For the four patients with poor prognosis, all had severe initial insults and widespread sinus thrombosis. MRI and MRA are better than CT for the diagnosis of cerebral venous thrombosis. It was concluded that prognosis for venous thrombosis cases in infants is worse than in older children, but this also depends on the severity of initial insults. For infants who present with intractable seizures, cerebral venous thrombosis should be taken into account when the seizures are difficult to control.

Tiagabine (TGB) hydrochloride is a potential new antiepileptic drug (AED) undergoing clinical development. Experience in humans amounts to 1,810 patient-years of exposure. TGB was found to be tolerated in an integrated safety analysis of five double-blind, add-on therapy trials involving approximately 1,000 patients with epilepsy with difficult-to-control seizures with existing AEDs. Discontinuation resulting from adverse events were infrequent, occurring in 15% of patients receiving TGB compared to 5% receiving placebo. The most frequently reported adverse event was dizziness, which was usually transient and did not require medical intervention. Adverse events that were statistically significantly more common with TGB than placebo were dizziness, asthenia, nervousness, tremor, diarrhea, and depression (not major depression). Adverse events were usually mild to moderate in severity and transient, and most were associated with dose titration. The incidence, type, and severity of adverse events in long-term studies were comparable with those in short-term studies. Serious adverse events were uncommon and no idiosyncratic events were reported.
