Ofloxacin-induced hallucinations.

Drug-induced hallucinations are not uncommon, and may be misdiagnosed as psychiatric illness leading to unnecessary treatment with antipsychotics. If a temporal association of use of a drug having the potential to cause hallucinations is present, mere withdrawal of the drug causes complete improvement in the symptoms. There are reports of various untoward central nervous system adverse events following administration of fluoroquinolones, including delirium, hallucinations and psychosis, even after a single dose.

Febrile myoclonus: a missed clinical diagnosis.

Myoclonic jerks presenting with fever have only rarely been reported and have often been misdiagnosed as febrile seizures. The presentation may be dramatic enough to provoke unnecessary investigation and treatment. Considering the benign nature of this condition, it is important that the condition is recognized by the physician so that hospitalisation and diagnostic procedures such as lumbar puncture and electroencephalogram are prevented.
