Human sperm chromosome studies in a reciprocal translocation t(2;5).

Sperm chromosome complements have been studied in a man heterozygous for a reciprocal translocation t(2;5)(p11;q15). Human sperm chromosomes were obtained after fertilization of zona-free hamster eggs. A total of 75 human sperm metaphases were analysed.

Epileptic psychosis: an evaluation of PSE profiles.

Data are presented on 24 patients with epilepsy and psychosis whose clinical presentation was rated using the Present State Examination (PSE). Seventeen had complex partial seizures and a diagnosis of temporal lobe epilepsy, seven had generalised epilepsy. An association between a CATEGO category of nuclear schizophrenia (NS) and a lesion of the left side was noted.

Assessment of weight loss, food intake, fat metabolism, malabsorption, and treatment of pancreatic insufficiency in pancreatic cancer.

In 12 patients with biopsy-proven pancreatic ductal adenocarcinoma, the following were determined: (1) whether decreased food intake, malabsorption, or altered fat metabolism were associated with weight loss; (2) the effect of pancreatic extract as treatment for malabsorption; and (3) the accuracy of the triolein breath test for detection of steatorrhea. Weight loss occurred in 11 patients and only in patients who had either malabsorption (n = 5), low coefficients of caloric consumption (n = 2), or both (n = 4). Nine patients had fat malabsorption, six had protein malabsorption, and caloric consumption was decreased in seven patients.

Epileptic psychosis--diagnostic comparison with process schizophrenia.

The mental states of 23 epileptic psychotic patients and 10 patients with process schizophrenia were compared, using the Present State Examination. The epileptics displayed marked heterogeneity of psychiatric diagnoses. Disturbances of affect underlying the psychosis or presenting as manic-depressive psychosis were frequent and independent of the type of epilepsy.

Effect of theophylline, terbutaline, and their combination on the immediate hypersensitivity skin-test reaction.

Methylxanthines and beta agonists can be expected to inhibit the antigen-induced hypersensitivity skin-test reaction by affecting cyclic 3', 5'-adenosine monophosphate (cyclic AMP) metabolism, yet in vivo studies produce conflicting results. The discontinuation of these drugs prior to skin testing may result in the exacerbation of asthmatic symptoms; however, if these drugs are maintained, the validity of the test remains in question. To determine the effect of these drugs on the skin-test response, 15 patients received theophylline, terbutaline, the combination, and placebo in a double-blind study.
