BACKGROUND Preliminary data suggest that decreased serum iron levels predict the progression of catatonia to neuroleptic malignant syndrome (NMS). This study examines the predictive value of low serum iron in this NMS conversion and explores other potential significance of serum iron in catatonia. METHODS Fifty patients with catatonia were prospectively… (More)
This study was performed to establish the incidence of catatonia in a psychiatric intensive care unit, to test the Bush-Francis Catatonia Screening Instrument (BFCSI) and to assess the response of catatonic signs to benzodiazepines. During a 12-month period all patients admitted to a psychiatric intensive care unit were screened for catatonic signs using… (More)
OBJECTIVE The purpose of this study was to examine the level of cannabis use in psychotic patients admitted to two acute admission wards in New Zealand. Symptomatology was investigated using the Brief Psychiatric Rating Scale (BPRS). METHOD During a 1 -month period, all acute admissions to Tokanui Hospital with psychosis were interviewed and symptoms… (More)
The psychotic manifestations of alcohol physical and psychiatric disorders have been documented for many centuries; however, the distinction of the various disorders remains less well defined. Individuals often have comorbid elements of several disorders, and the psychotic phenomenon are often diverse. The psychotic manifestations of alcohol withdrawal,… (More)
Catatonia as a clozapine withdrawal syndrome has not been documented. We report a case of excited catatonia with fever, autonomic instability, and delirium--a picture of malignant catatonia (lethal catatonia) after abrupt clozapine withdrawal. The use of conventional neuroleptics transformed the excited malignant catatonia into a stuporous state resembling… (More)
BACKGROUND/AIMS We developed a new endoscopic biopsy training simulator and determined its efficacy for improving the endoscopic biopsy skills of beginners. METHODS This biopsy simulator, which presents seven biopsy sites, was constructed using readily available materials. We enrolled 40 participants: 14 residents, 11 first-year clinical fellows, 10… (More)
Colonic perforation may occur as a complication of diagnostic and therapeutic colonoscopy. The risk factors for perforation after colorectal endoscopic submucosal dissection (ESD) include an inexperienced endoscopist, a large tumor size, and submucosal fibrosis. The mechanisms of perforation include unintended endoscopic resection/dissection and severe… (More)
I describe a case of recurrent delirium associated with OSA in a morbidly obese man. Continuous positive airway pressure (CPAC) therapy alleviated the OSA and delirium but was only partially effective in preventing relapses of delirium. Gastric stapling helped to secure considerable weight loss with reversal of OSA and no further recurrence of delirium.
