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.

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.

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.
