Six circus lions (Panthera leo) showed neurological and gastrointestinal signs after consuming casualty broiler chickens. Signs included ataxia, hindlimb paralysis and recumbency. Neurological examination of two affected males showed paralysis of extraocular muscles, fixed dilated pupils and
An unusual presentation of type F botulism (one of the world's three reported outbreaks) is described. The diagnosis was complicated by the presence of pre-existing Adie's myotonic pupil. There was also a history of self-inflicted small-caliber gunshot wound to the right brain 10 years before the
We report a foodborne outbreak causing a cholinergic syndrome in three members of a family. The clinical presentation was characterized by nausea, vomiting, abdominal pain, and weakness. Physical examination revealed evidence of peripheral motor weakness and decreased level of consciousness in all
The central nervous system is separated from the rest of the body by the blood-brain barrier. This barrier prevents many substances, such as the antibodies, to penetrate into the brain making it difficult to use them for the treatment of brain diseases, such as tetanus and botulism. These two
4-aminopyridine is the first of the aminopyridines to be used in clinical practice. It blocks potassium channels and thereby increases acetylcholine, and possibly noradrenaline, release at nerve terminals. In man the drug has a significant action at the neuromuscular junction, but has little effect
A low molecular weight substance that induced seizures and death in mice was present in the stool of a child with infant botulism. This interfered with mouse bioassay used for detecting Clostridium botulinum toxin. After removal of the interfering substance by a prolonged dialysis with buffered
We encountered three patients (Patient I: 39-year-old man, Patient II: 34-year-old woman, and Patient III: 5-year-old girl) with acute methyl bromide poisoning, which had occurred as a result of exposure to the gas that leaked from methyl bromide cans stored in a warehouse of a seedling farm. Since
3,4-Diaminopyridine has shown promise in reversing botulinum intoxication, but poor pharmacokinetics and a narrow therapeutic window limit its clinical utility. Thus, we developed a pH-dependent oral delivery platform using club moss spore exines. These exine microcapsules slowed 3,4-diaminopyridine
BACKGROUND
4-Aminopyridine (4-AP) selectively blocks voltage-gated potassium channels, prolongs the action potential, increases calcium influx, and subsequently, enhances interneuronal and neuromuscular synaptic transmission. This medication has been studied and used in many disease processes
