A 36-year-old man with prolonged confusion developed after psychomotor status was reported. He had no past history of epileptic seizures or psychotic disorders. The status continued for 20 hours, and twilight state and a slight fever lasted for about 10 days. Thereafter gross impairment of memory and disorientation became remarkable, and, in addition, strong psychic and autonomic disturbances developed, such as visual and auditory hallucinations, excessive excitement, disturbance of sleep, polyphagia, polydypsia, polyuria and hyperhidrosis. The CT scan, carotide angiography, CSF examination, and complement fixation tests for viruses were all within normal limits. The EEGs showed a slowing of the background activity, 0.6--0.8 Hz periodic high voltage wave discharges and random spikes in each temporal area. The clinical symptoms and EEG findings gradually improved without remarkable damage.

An acute limbic-cerebellar syndrome was seen in six industrial workers who inhaled trimethyltin (TMT). Clinical features included hearing loss, disorientation, confabulation, amnesia, aggressiveness, hyperphagia, disturbed sexual behavior, complex partial and tonic-clonic seizures, nystagmus, ataxia, and mild sensory neuropathy. Severity paralleled maximal urinary organotin levels. One patient died and two remained seriously disabled.

A 12-year-old boy had been treated with multiagent chemotherapy for acute mixed lineage leukemia and with intravenous hyperalimentation due to persistent diarrhea and vomiting for 2 months. He suddenly complained of horizontal nystagmus and gait disturbance followed by oculomotor palsy and disorientation within a few days. Blood tests revealed low serum vitamin B1 and high serum pyruvate. Magnetic resonance imaging in T2-weighted axial image revealed a high signal inside the bilateral thalami, mamillary bodies and periaquaductal gray matter. He was diagnosed as Wernicke's encephalopathy and successfully treated with vitamin B1. Careful observation and adequate treatment are emphasized in the management of this preventable and curable disease.

A 54-year-old man presented with visual disturbance and polydipsia. Magnetic resonance imaging disclosed a cystic mass which extended from the intrasellar to the suprasellar region. Bifrontal craniotomy was performed and the tumor was totally removed. Histological findings confirmed the diagnosis of craniopharyngioma. Postoperatively, the patient suffered from transient disorientation. About one month after the operation the patient manifested hyperphagia and he gained 15 kg in one month. Mazindol, a non-amphetaminergic anorectic agent, was administered for 3 weeks. His appetite normalized and his weight fell and stabilized even after mazindol administration was ceased.

The clinical, neuropathologic, and magnetic resonance (MR) imaging features in four cats with necrosis of the hippocampus and piriform lobe are described. All cats had acute generalized seizures and behavioral changes including aggression, salivation, polyphagia, and disorientation. Routine hematologic, serum chemistry, and cerebrospinal fluid analyses were normal. MR imaging abnormalities were restricted to the area of the hippocampus and piriform lobe. The lesions were T2-hyperintense, T1-hypointense, and were characterized by various degrees of contrast enhancement. Lesions were consistent with necrotizing encephalitis. Two cats were euthanized and underwent postmortem examination within a week after MR imaging due to the lack of response to antiepileptic drug therapy and progressive encephalopathy [corrected] The remaining two cats lived for about four months and were then euthanized because of persistent behavioral and neurologic signs; only one of these cats underwent postmortem examination with histopathologic examination. Histopathological findings were typical of severe, diffuse, bilateral symmetric necrosis, and degeneration of neurons in the hippocampus and piriform lobe, but an etiologic agent was not apparent. This apparently unique feline syndrome, now reported in Switzerland and Italy, has no known cause at this time.
