Oculogyric crisis is an acute dystonia involving ocular muscles characterized by sustained conjugate upward or lateral deviation of the eyes. Metronidazole is a commonly used antimicrobial agent in treatment of anaerobic infections. However, its long-term use can cause toxic encephalopathy particularly in patients with hepatic dysfunction. Here, we describe a case of oculogyric crisis as a presenting manifestation of metronidazole-induced encephalopathy.

BACKGROUD: It is generally acknowledged that a close relationship exists between chronic alcohol abuse and the occurrence of alcohol withdrawal seizure(AWS). About one third of AWS patients have been reported to be followed by delirium tremens (DT). OBJECTIVES: We assessed the factors that have influence on the development of DT in AWS patients. METHODS: We investigated clinical features and laboratory findings of 39 AWS patients who were admitted. The following factors were analyzed ; duration of alcohol intake, interval from last drinking to onset of AWS, interval from AWS to treatment, number of seizure, fever, laboratory findings (Mg, K, Na, Ca, P, respiratory alkalosis). RESULT: Fourteen patients developed DT(35.8%). There was fever in 36% of AWS patients with DT(5/14) and in 8% of AWS patients without DT(2/25). Number of seizure (p<.05) and interval from AWS to treatment(p<.01) showed statistically significant difference. But other factors were insignificant statistically. CONCLUSION: Our study suggests that number of seizure and interval from AWS to treatment seem to be significantly related to the development of DT in AWS patients.

Metronidazole is commonly used for brain abscess but is not well known for its neurotoxic complications. Metronidazole-induced encephalopathy (MIEP) is toxic encephalopathy associated with the use of metronidazole. We experienced a case of brain abscess which developed reversible severe MIEP during treatment period. Although MIEP occurs in typical locations, it is not easy to differentiate from other conditions such as cerebral infarction, demyelinating diseases and metabolic diseases. Neurosurgeons should be aware that severe MIEP can occur during the use of metronidazole though it is not common.

Viagra has been prescribed worldwide to treat men with erectile dysfunction. Clinical trials have shown that Viagra may cause various kinds of adverse effects include some central nervous system (CNS) adverse effects. Although extremely rare, toxic encephalopathy also can be one of those effects. This report presents a case of encephalopathy caused by Viagra in correlation with its radiologic findings. Its pharmacologic mechanism and potential effects on the biochemistry of the CNS are reviewed.

Long-term occupational exposure to manganese might cause manganese poisoning, which would had adverse effects on nervous system of workers. The basal nucleus was damaged and dopaminergic neuron was injuried by manganese. The mechanism could be related with interfering the energy metabolism of central nerve, changing neurotransmitters, activating oxidation system and so on. Genetic factors may also plays a significant role in the neurotoxicity caused by manganese. Study the effects of manganese exposure biomarker, the neurotoxicity of biomarkers and the genetic susceptibility to early and susceptibility biomarkers will contribute to the prevention and control of manganese neurotoxicity.
