Risperidone in Indian patients with schizophrenia.

Conventional antipsychotic agents are not effective against negative symptoms of schizophrenia and are also noted for their extrapyramidal side effects. Risperidone is a noval antipsychotic agent whose dual antagonism of dopamine and serotonin receptors is believed to underlie its efficacy against negative symptoms and the low incidence of extrapyramidal side effects. An open, non-comparative study of seven weeks duration was performed to evaluate risperidone in the treatment of schizophrenia in Indian patients. Previous antipsychotic therapy was discontinued for a week before risperidone therapy was initiated. At the end of six weeks of risperidone therapy, clinical improvement (≥ 20% reduction in total score on positive and negative syndrome scale for schizophrenia (PANSS;; was shown by 128 (87.7%) of the 146 evaluable patients. Statistically significant reduction (p < 0.05) occurred in the total score of this scale and in the subscale scores for positive, negative and general psychopathology symptoms and in the clinical global impression severity score. The number of patients with adverse experiences were 108 (65.5%) at baseline and 120 (72.7%) at the end of risperidone therapy. Extrapyramidal symptoms, seen in 65 (39.4%) patients compared to 22 (13.3%) patients at baseline, were largely mild to moderate in intensity.

Psychosocial aspects of amputation.

Twenty-five subjects were studied who had undergone amputation 6 months to 2 years prior to the time of assessment. The sample was divided into sick (those having psychiatric illness) and non-sick (those without any psychiatric illness) groups, and then compared for various life events following the amputation. It was seen that those who were labelled as psychiatrically sick had more work impairment, change in job, socioeconomic difficulties and social avoidance. The latter two factors were also significantly more in right upper limb amputees than the left upper limb amputees; no such difference existed between the upper and lower limb amputees.

Psychiatric sequelae of amputation : I immediate effects.

Twenty-five subjects, who had undergone amputation within last 6 weeks, were studied for psychiatric complications, including phantom limb phenomena. The patients were interviewed on SCID, HRSD and HARS. Out of a total of 25 subjects, 8 (34.6%) developed psychiatric disorders - PTSD and major depression. The whole sample was thus divided into 2 groups-sick and nonsick. Phantom limb was seen in 88% subjects. No significant difference was present between the two groups with regard to presence of phantom, its associated phenomena of pain, telescopy and movement. A statistically significant difference was seen in psychiatric sickness in relation to upper and lower limb.

Psychiatric sequelae of amputation : ii long term effects.

Psychiatric sequelae present after 6 months to 2 years following amputation were studied in a group of 25 subjects. The subjects were screened on SCID, HRSD and HARS. The most common diagnoses were depressive disorder NOS (20.6%) and major depressive disorder (10.3%). Patients having right sided amputation were more psychiatrically ill than those with loss of a left limb. Phantom limb was seen in about two-thirds of the total sample-more in the sick group (about 88%) than in the non-sick group (about 55%). Pain in the phantom limb was seen more in the sick group, but telescopy and movement were more frequently complained of by subjects of the non-sick group.
