OBJECTIVE This study explored the relative efficacy of three different doses of clozapine. METHOD Fifty patients who met Kane et al.'s criteria for treatment-refractory schizophrenia or schizoaffective disorder were studied. All subjects were randomly assigned to 100, 300, or 600 mg/day of clozapine for 16 weeks of double-blind treatment. Forty-eight(More)
OBJECTIVE This study was designed to prospectively examine differential effects of sustained "high" and "low" serum prolactin levels on bone mineral density and peripheral markers of bone metabolism. METHOD A dual-energy X-ray absorptiometer was used to measure bone mineral density. Peripheral markers of bone formation and resorption were used to measure(More)
Laparoscopic adrenalectomy is the standard of care for management of adrenal neoplasms. However, large sized adrenal lesions are considered as relative contraindication for laparoscopic extirpation. We report laparoscopic excision of giant ganglioneuroma of adrenal gland in a 33-year-old female patient. Patient was presented with left loin pain of 2 months(More)
A retrocaval ureter is a rare congenital cause of upper ureteric obstruction that results from entrapment of the upper ureter by the inferior vena cava (IVC) as it courses posterior to the cava. We report an interesting scenario of upper ureteric obstruction secondary to entrapment between twin segments of IVC.
Patients with chronic schizophrenia suffer from alterations in cholinergic functioning due to several factors, including the disease diathesis and pharmacologic treatments. Acetylcholine-cognition relationships are well explored in normals but are unclear in schizophrenia. Prior work indicated serum anticholinergicity does not cause global cognitive(More)
BACKGROUND A potential beneficial outcome of treatment with certain of the atypical neuroleptics is the reduced risk of cognitive impairment, stemming from purported low affinity for cholinergic receptors. In vitro experiments have shown that clozapine is highly anticholinergic and risperidone is minimally so. In vivo tests of the anticholinergic burden(More)
Preliminary results of a double-blind clozapine study in a population of chronic psychotic patients at a state psychiatric facility are reported. Thirty "treatment-refractory" schizophrenic patients given a diagnosis according to DSM-III-R criteria (mean age of 44 +/- 9.1 years and a duration of illness of 24.9 +/- 8.8 years) who received 300 mg or 600 mg(More)
