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.

This is a case report of a twenty-five years old man who developed, due to lead intoxication, a severe axonal peripheral predominantly motor neuropathy, after a shotgun injury. The projectile was retained in the right hip. Before this diagnosis had been done he was treated with corticosteroids in immunosuppressive doses and showed an improvement, but he had worsened at each attempt to interrupt the drug. Because he had also other signs of lead intoxication, such as abdominal cramps, severe anemia and seizures it was search for the blood levels of lead that was 101.2 micrograms/dl. The patient was treated with calcium disodium edetate and surgical removal of lead fragments. After that he had a good outcome with no need of corticosteroids. It is emphasized the possible relevance of the immune system on the mechanism of plumbic intoxication and the importance of the withdrawal of the lead material retained in joints.

Thirteen children with refractory epilepsy received a ketogenic diet (medium chain triglyceride oil diet) as an alternative therapy since September 1997. Their seizure patterns included (1) generalized tonic-clonic seizures, (2) myoclonic seizures, (3) generalized tonic + atonic seizures, (4) complex partial seizures, (5) generalized clonic + atonic + myoclonic seizures, (6) head nodding + myoclonic + gelastic seizures, and (7) generalized tonic-clonic + myoclonic + atonic seizures. Major concerns emphasized on the efficacy and side effects of the diet. Clinical observation one month after the diet revealed that 53.8% of the patients had a > 75% reduction in seizure frequency and 76.9% of the patients had a > 50% reduction in seizure frequency. Six patients had some degrees of improvement in cognitive function and/ or school performances. The most common side effects were body weight loss (n = 6) and diarrhea (n = 5). Others included bad temper (n = 1), abdominal cramps (n = 2), nausea (n = 2), bad body smell (n = 1), and renal stones (n = 1). Even after discontinuation of the diet, 61.5% of patients still had a > 50% reduction in seizure frequency. We concluded that the ketogenic diet deserves a trial in children with refractory epilepsy.

Valproic acid is a widely used drug in the treatment of epilepsy and, compared to other anticonvulsant drugs, is considered safe. The most common side effects of valproic acid ingestion or therapy are transient nausea, vomiting, abdominal cramps, and diarrhea. Most of these complaints are mild. However, more serious adverse reactions can occur such as hepatotoxicity and pancreatitis. It has been proposed that, whenever possible, valproic acid not be used in the younger child, the child with a severe seizure disorder or other neurological disorders, mental retardation, developmental delay, organic brain disease, congenital abnormalities, or the child who is taking multiple anticonvulsant drugs, as these factors may increase the likelihood of hepatotoxicity and/or pancreatitis. In the present report, we describe a fatal case of acute hemorrhagic pancreatitis in a four and a half-year-old Hispanic female child who was receiving valproic acid in combination with another anticonvulsant drug for control of focal seizures. The patient also received the macrolide antibiotic azithromycin. For pediatricians and forensic pathologists valproic acid-induced pancreatitis can be a challenging diagnosis which must not be mistaken for abdominal trauma. We discuss the workup of the patient and differential diagnosis.

A 9-year-old girl was managed according to the COPRALL 04 protocol for treatment of a relapse of acute lymphoblastic leukemia. Owing to a previous case of disseminated fusariosis, posaconazole was started 5 days before initiation of chemotherapy. Six days after the last dose of vincristine, the child reported symptoms of severe peripheral neuropathy, abdominal cramps, and constipation. After this, she developed fluctuations in her level of consciousness and seizures. After cessation of therapy with posaconazole, a complete resolution of the above occurred within 7 days. This case illustrates the possibility of vincristine toxicity exacerbated by coadministration of posaconazole. As posaconazole is an inhibitor of the isoenzyme CYP3A4, interactions with drugs that are metabolized via this pathway, such as vincristine, can be anticipated. Another possibility is that, like itraconazole, posaconazole may also inhibit P-glycoprotein-mediated vincristine efflux. Although case reports of neurotoxicity owing to possible interaction between itraconazole and vincristine exist in the literature, only 1 case report relating to the possible interaction between posaconazole and vincristine exists. Clinicians should be made aware of this possible drug-drug interaction.
