Fulminant subacute sclerosing panencephalitis in association with pregnancy

Subacute sclerosing panencephalitis developed during pregnancy in a 27-year-old woman and immediately after delivery in an 18-year-old woman. In both, disease took an acute and fulminant course culminating in a vegetative state within several weeks. It is suggested that the relative older age of disease presentation and the unusually rapid neurologic deterioration were partially due to immunologic and hormonal alterations of pregnancy.     

Perinatal protein deprivation enhances the anticonflict effect measured after chronic ethanol administration in adult rats.

The anticonflict effects of ethanol, diazepam and pentobarbital were evaluated in adult rats fed a low protein diet during the perinatal period in the plus-maze test, after single injections and following chronic ethanol administration (1 g.kg-1.d-1 for 30 d). Reactivity to the anticonflict effect of these drugs was similar in control and protein-deprived rats after acute treatment. After chronic ethanol administration, control rats showed tolerance to ethanol and cross-tolerance (i.e., lower reactivity) to the anxiolytic effect of diazepam and pentobarbital. Conversely, protein-deprived rats showed greater reactivity to ethanol and lack of cross-tolerance to diazepam and pentobarbital following chronic ethanol treatment. A significantly greater density of cortical gamma-aminobutyric acid receptors subtype A (GABA-A) was detected in protein-deprived rats after chronic ethanol administration compared with the density after chronic saline treatment, whereas no differences were observed in nourished controls. This suggests that the greater anxiolytic activity detected in protein-deprived rats may correlate with higher GABA-A receptor density.     

Return to training and competition after deep venous calf thrombosis.

A 25-yr-old female triathlete presented with 4 d of increasing left calf pain that started 1 d after an elective termination of pregnancy during the eighth week of gestation. She had been training with running, bicycling, and swimming but did not recall any injury to the calf muscle. Deep venous thrombosis of the calf and popliteal veins was diagnosed, and she was treated with intravenous heparin and oral warfarin anticoagulation. Her major concern was return to training and competition. A protocol was developed based on experience with less active patients and animal studies to allow a progressive return to training activities over 5 wk, followed by running in the sixth week. After release from the hospital, she accelerated the return-to-training protocol and progressed to running within 3 wk. She developed the post-phlebitic syndrome that resolved within 2 yr. The diagnosis and treatment of deep venous thrombosis are reviewed, with specific attention to the needs of athletic patients.     

Hypoglycemic drugs.

There are an estimated 14 million individuals in the United States with diabetes mellitus. These individuals suffer a very high incidence of podiatric complications. This article focuses on the pharmacologic agents used in the management of hyperglycemia in the patient with diabetes mellitus, including insulin and sulfonylureas.     

The impact of HIV disease on an Irish prison population.

Between January 1987 and January 1991, 168 known HIV-infected prisoners have been incarcerated in Dublin's Mountjoy prison. This figure constitutes 16.6% of the total HIV-infected population in the Republic of Ireland over the same period. One hundred and forty-one (84%) of these prisoners have attended the Department of Genitourinary Medicine, St James's Hospital, Dublin. This group displayed considerable morbidity from HIV-related disease. Respiratory tract infection was the most frequent complication seen. Much additional morbidity was directly attributable to intravenous drug use. A survey of a representative group of inmates revealed that 64.7% were diagnosed HIV-positive in prison. The mean length of time spent incarcerated since the diagnosis of HIV infection was 38.9 months. Twenty-nine of 34 individuals who answered a questionnaire were imprisoned for drug-related crimes and 32 of 34 prisoners admitted to parenteral drug use within the prison. As the HIV epidemic unfolds in Dublin, increasing numbers of prisoners with symptomatic HIV disease will spend time incarcerated in Mountjoy prison. This will pose a considerable burden on prison and hospital medical services alike.     

Features of the formation, expression and transmission of basic genetic and androgen programs of the level of unusual estrogen-binding protein in sexually mature female rat hepatocytes under experimental conditions]

Some features of the formation, expression and inheritance of basic genetic and androgen programs of the level of unusual estrogen-binding protein (UEBP) in mature female rat hepatocytes under experimental conditions were investigated. Liver regeneration after partial (2/3) hepatectomy of mature rats was used for generation of a new population of differentiated hepatocytes. The UEBP content was determined by radioligand technique in control liver and at 2, 4, 14 days of liver regeneration and related to the total DNA content as an indicator of cell proliferative activity. It was revealed that the basic genetic program of low UEBP level of hepatocytes of ovariectomized females was fully transferred to daughter cell during cell proliferation and characterized by a temporary elevation of its expression during initial steps of liver regeneration. It was shown that the androgen program of a high UEBP level was completely and stably formed after androgen action in hepatocytes of ovariectomized females and was fully transferred to daughter cells during hepatocyte proliferation. However experimentally formed androgen program of a high UEBP level in female hepatocytes was completely revealed only during early steps of liver regeneration (the 4th day), its expression was essentially declined after regeneration process was over.     

Effects of orchiectomy and polyestradiol phosphate therapy on serum lipoprotein lipids and glucose tolerance in prostatic cancer patients

In 17 prostatic cancer patients, changes in the plasma lipoprotein pattern, including high density lipoprotein (HDL) subfractions, and in glucose tolerance were compared after 6 months on parenteral polyestradiol phosphate (PEP; Estradurin, 80 or 160 mg/month) with the respective changes in orchiectomized patients. In the estrogen group there was no change in the total serum cholesterol level, whereas in the orchiectomy group an increase of 10% was observed. Estrogen therapy resulted in a significant increase of serum HDL (11%) and HDL2 cholesterol (26%) levels; in the orchiectomy group these fractions remained unchanged. Estrogen therapy induced a significant decrease in total serum triglycerides (24%) and in low density lipoprotein triglycerides (27%); in the orchiectomy group reverse changes were observed. PEP treatment caused changes in the serum lipoprotein pattern, which apparently decreases the risk of atherosclerosis.
