Common peripheral vascular diseases.

Among the most common causes of morbidity and mortality in elderly individuals are the manifestations of the various peripheral vascular diseases. Many chronic degenerative diseases, which begin in middle age, are associated with peripheral vascular disease. Heart disease, hypertension, hyperlipidemia and diabetes are all risk factors for peripheral vascular diseases and also common degenerative conditions in our society. Other risk factors, such as diet, smoking, stress, lack of exercise, and obesity, are also closely associated with peripheral vascular disease. Aging itself is also a risk factor. Appropriate treatment for disease processes such as diabetes and hypertension and control of other preventable risk factors have been shown to reduce the morbidity and mortality seen in peripheral vascular disorders. Our rapidly aging population requires increasing amounts of medical resources, placing an enormous burden on society because the aged population are generally more dependent upon government-sponsored health care services. The podiatric practitioner is in a position as a primary care provider to influence the health practices of our aging population. The implementation of a health practice that stresses prevention and wellness as well as the appropriate management and a referral of patients with peripheral vascular disorders will limit the morbid results of peripheral vascular diseases.

Influence of bovine somatotropin and nutrition on production and composition of milk from dairy cows.

Forty-eight multiparous Holstein cows were used in an experiment with a 2 x 2 factorial arrangement of treatments to study interactions of bST and nutrient density during wk 5 through 20 postpartum. Main effects were bST (0 or 10.3 mg/d) and diet (control or high protein and energy). The control diet was formulated to contain 16.3% CP and 1.65 Mcal of NEL/kg of DM; the high protein and energy diet was formulated to contain 18% CP and 1.74 Mcal of NEL/kg of DM with additional energy as fat from extruded soybeans and calcium salts of fatty acids. Diet ratios were 50:25:25 for concentrate:alfalfa hay:corn silage (DM basis). Bovine somatotropin increased milk production (40.9 vs. 37.9 kg/d) and production of 4% FCM (35.7 vs. 32.3 kg/d). The high protein and energy diet increased milk production (40.3 vs. 38.5 kg/d); 4% FCM production was higher for high protein and energy plus bST (36.0 kg) than without bST (33.6 kg). Percentage of milk fat was not affected by treatment. Percentage of milk protein was reduced with the high protein and energy diet, presumably because of the added fat, but this reduction was less with high protein and energy plus bST. Dry matter intake was not significantly elevated by bST (23.1 vs. 22.8 kg/d) but was lower for high protein and energy (22.0 vs. 23.8 kg/d). Increased dietary protein and energy with bST augmented the total milk production response.

Successful kidney trasnplant in patient with positive crossmatch due to autoantibodies.

Prior to kidney transplantation a young woman was found to have lymphocytotoxic antibodies to an HLA/mixed lymphocyte culture identical sib donor. The serum killed 75% of the lymphocytes at 22 C but was unreactive at 37 C. At room temperature it was cytotoxic for many lymphocytes of a random panel and also reacted with the recipient's own cells. Complement was required for cytotoxicity. Absorption with lymphocytes but not with platelets abolished the reaction. The antibodies disappeared spontaneously and the transplant was performed. There was no evidence of rejection and at 6 months the kidney is in excellent condition. Cold-reactive lymphocyte specific autoantibodies causing a positive crossmatch could be distinguished from anti-HLA antibodies and did not preclude a successful kidney transplant.
