Effect of clozapine on physical and verbal aggression.

OBJECTIVE: The hypothesis that clozapine reduced serious physically and verbally aggressive behavior of persons with schizophrenia whose symptoms did not respond to typical neuroleptic treatment was tested. METHOD: Incident reports of aggression and restraint of 75 such inpatients were reviewed for 3 months before clozapine treatment and for 6 months of clozapine treatment. BPRS scores were also examined. Twenty-eight patients with no incidents were removed from study. RESULTS: There were significantly fewer incidents of physical aggression per month per patient on clozapine than before clozapine (mean +/- S.D. = 0.13 +/- 0.25 vs. 0.54 +/- 0.93; t = 3.4, df = 46, p < 0.002) and a similar decline in verbal aggression (0.21 +/- 0.31 vs. 0.73 +/- 0.83; t = 4.3, df = 46, p < 0.000). On clozapine, 49% (n = 23) of patients had fewer incidents of physical aggression, 36% (n = 17) showed no change and 15% (n = 7) showed more. Seventy percent (n = 33) of patients had fewer incidents of verbal aggression, 4% (n = 2) showed no change and 25% (n = 12) had more. During the 3 months before clozapine, 14 patients (30%) were restrained a total of 40 times. During the first 6 months of clozapine treatment, three patients (6%) were restrained a total of six times. There were significant decreases in BPRS hostility, positive, negative and psychosis scores. CONCLUSION: Clozapine appears to reduce serious aggression among some patients.

Hodgkin's lymphoma in an adolescent with systemic lupus erythematosus.

An adolescent female with systemic lupus erythematosus (SLE) with diffuse proliferative lupus nephritis subsequently contracted Hodgkin's lymphoma, mixed cellularity type. Prior to the diagnosis of Hodgkin's lymphoma, hypogammaglobulinemia developed with IgG deficiency. The nephritis, which improved on steroid therapy, remitted entirely after nitrogen mustard, vincristine, procarbazine, and prednisone (MOPP) therapy. The hypogammaglobulinemia also remitted after chemotherapy for Hodgkin's lymphoma. The literature concerning the association of SLE and Hodgkin's lymphoma is reviewed. The significance of this concurrence is discussed in regard to the possible pathophysiology and the clinical management.

Malignant melanoma of the external ear. Review of 102 cases.

The medical records of 102 patients with a diagnosis of melanoma of the external ear seen at The M.D. Anderson Hospital over approximately a 30 year period were reviewed. Survival was correlated with the sex, the clinical appearance of the lesion, the anatomic site of origin, the microscopic thickness and level of invasion, the absence or presence of clinical and pathologic nodal metastasis, the type of neck dissection and the type of definitive surgical treatment to the ear. The thickness and nodal metastasis adversely affected prognosis. Proper surgical treatment usually involves less than total amputation of the ear. A randomized prospective study should answer the question of whether elective neck dissection of the periauricular, parotid and upper posterior cervical and jugulodigastric nodes is justified. The use of chemoimmunotherapy offers a negligible therapeutic benefits for disseminated disease but may be of prophylactic value in a planned, adjunctive protocol for poor risk patients.

Influence of a synthetic prostaglandin analog on pancreatic secretion.

Effects of a synthetic prostaglandin analog-16--16-dimethyl prostaglandin E2, methyl ester (16-diMe-PGE2)--on pancreatic secretion were evaluated in seven dogs with chronic duodenal fistulas. Graded doses of 16-diMe-PGE2 were administered intravenously (0.1, 0.3, 0.5, and 1.0 mug per kilogram, intraduodenally, or intragastrically (15, 30, 50, 100 mug per kilogram) with the pancreas in the resting state or in response to (1) secretin and (2) secretin with cholecystokinin-pancreozymin. Profound and prolonged inhibition of volume and bicarbonate concentration of secretion occurred in the resting and stimulated gland. ED50 was 0.31 mug per kilogram intravenously (1/75 the ED50 for PGE1) and 25 mug per kilogram intraduodenally. As with PGE1, stimulation of enzymes occurred, even with doses that were subthreshold for inhibition of volume and HCO3. Like PGE1, 16-diMe-PGE2 has a dual action on the intact canine pancreas (stimulation of enzymes and inhibition of volume and electrolytes), but is much more potent, has a prolonged action, and is active intraduodenally and intragastrically. Nonsteroid inhibitors of endogenous prostaglandin synthesis did not alter these effects.

Pancreatic exocrine secretion during and after pregnancy.

Pancreatitis occurring in late pregnancy and in the puerperium has been documented as an entity unrelated to cholelithiasis or hyperlipidemia. Canine pancreatic exocrine function has been studied during pregnancy and the puerperium. Pancreatic secretion was evaluated in eight pregnant female mongrel dogs prepared with Thomas duodenal and gastric fistulae, during pregnancy (corresponding to the third trimester in humans), during the puerperium, and several months after whelping. Basal secretion (volume and HCO3) was increased during pregnancy and the puerperium. The response to exogenous secretin (submaximal and maximal) was unchanged during pregnancy but decreased in the puerperium. Resting enzyme output was increased during pregnancy and the puerperium; the responses to cholecystokinin-pancreozymin during pregnancy were even more profoundly increased. Although the mechanism is speculative, these alterations in pancreatic function might contribute to the development of pancreatitis in pregnancy and the puerperium.
