There had been few reports of arachnoid cyst accompanying psychiaric disturbance and no report treated with low-dose resperidone administration. We report a patient, developed first-transient psychotic episode considered to be provoked by an arachnoid cyst, responsive to risperidone, which was found in the middle cranial fossa as follows. A 57-year-old man was admitted by suddenly developed headache, auditory hallucination, delusion of persecution and, an arachnoid cyst in the anteromedial aspect of middle cranial fossa was found on MRI after admission. The psychotic episode was first to him and he was also negative to other clinical evaluation including endocrine abnormality, his psychotic symptom was suspected to be induced by arachnoid cyst and was well controlled to low-dose risperidone administration. He left hospital free from psychotic symptoms on 14 hospital days.

OBJECTIVE: Immediate early gene (IEG), c-fos is known to encode a 62 kDa nuclear protein (Fos) which has a critical role in the stimulus response process of many cells. c-fos can be activated in the central nervous system by a variety of physiological and pharmacological treatment. Recently evidences has been reported suggesting that glucocorticoid hormones, which are released from adrenal cortex in response to stress, may regulate IEG expression. We observed whether immobilization stress or corticosterone altered the induction of c-fos by haloperidol in the nucleus accumbens, lateral striatum, and prefrontal cortex. METHODS: Twenty-four healthy Wistar rats of male sex, weighing 300-450 g, were divided into 6 groups according to injection agents [vehicle (1 mg/kg), haloperidol (1 mg/kg), corticosterone (1 mg/kg), immobilization stress, haloperidol (1 mg/kg) and corticosterone (1 mg/kg), haloperidol (1 mg/kg) and immobilization stress] respectively. Fos-immunoreactivity was measured by counting of Fos-positive neurons in the nucleus accumbens, lateral striatum, and prefrontal cortex. RESULTS: (1) The number of Fos-positive neurons in the nucleus accumbens was significantly decreased in the haloperidol plus immobilization stress group and haloperidol plus corticosterone group compared with that in the haloperidol group (p<0.05). (2) The number of Fos-positive nurons in the lateral striatum was significantly decreased in the haloperidol plus corticosterone group compared with that in the haloperidol group, but the number of Fos-positive neurons in the lateral striatum was not significantly different between the haloperidol plus immobilization stress group and the haloperidol group (p<0.05). (3) The number of Fos-positive neurons in the prefrontal cortex was significantly increased in the haloperidol plus immobilization stress group and haloperidol plus corticosterone group compared with that in the haloperidol group (p<0.05). CONCLUSION: These results suggest that regulatory process exerted by corticosterone may alter the antipsychotic effect of haloperidol.

Atenolol is a beta1-selective adrenoreceptor blocking agent which is generally thought of as cardioselective, with little CNS action, because it has hydrophilic solubility rather than lipophilic. But recently, it has been reported that atenolol also can cause CNS side effect, especially in the patient with past neuropsychiatric history, old age, or underlying cerebral lesion. This 59-year-old female case demonstrated that atenolol could be an etiological agent of visual hallucination in a elderly patient with cerebral infarction.

OBJECTIVES: The purpose of this study was to investigate the effects of methysergide(serotonin receptor antagonist) on serum growth hormone response after electroconvulsive therapy(ECT). METHODS: We studied the changes of the serum growth hormone levels of the day before ECT(No ECT), ECT without methysergide pretreatment(ECT alone), and ECT with methysergide pretreatment(M+ECT) by radioimmunoassay method in 14 psychiatric patients. ECT was induced by the application of 110 volts for a period 0.3-1.0 second, using bitemporal electrodes. RESULTS: 1) Serum growth hormone levels at 15, 30, and 60 minutes after ECT were significantly increased in the ECT alone group than in the No ECT group(p<0.05). 2) Serum growth hormone levels at 15, 30, and 60 minites after ECT were significantly decreased in the M+ECT group than in the ECT alone group(p<0.05). CONCLUSION: These results suggest that the response of growth hormone after ECT seems to be mediated by the activation of serotonergic system.
