Hepatosplenic lymphoma in a dog.

We describe a case of a dog with hepatosplenic lymphoma, a disease characterized by infiltration of the liver, spleen, and bone marrow with gammadelta T cells, absence of peripheral lymphadenopathy, and an aggressive clinical course. Physical examination findings, hematologic and biochemical abnormalities, and clinical course of the disease in this patient were similar to those in humans. Immunophenotyping of liver and spleen aspirates supported an antemortem diagnosis of T-cell lymphoma consistent with hepatosplenic lymphoma. The diagnosis was confirmed postmortem by a combination of routine histopathology, showing a consistent pattern of organ involvement, and immunohistochemistry showing the infiltrating neoplastic lymphocytes to be T cells expressing the gammadelta T-cell receptor. To our knowledge, this is the first reported case of hepatosplenic lymphoma in a dog.

The food and nutrient intakes of the Tarahumara Indians of Mexico.

A nutritional survey of 372 semiacculturated Tarahumara Indians in the Sierra Madre Occidental Mountains of Mexico was carried out to determine the composition of their diet and its nutritional adequacy. Dietary histories from 174 adults and 198 children were obtained by interviews and field observations during 1973 and 1974. The histories for the children were calculated in part from the menus of six boarding church schools. Nutrient calculations of daily intake were based upon food composition tables and some actual analyses of Tarahumara foods. The protein intake was ample, at 87 g, and generously met the FAO/WHO recommendations for daily intake of essential amino acids. Fat contributed only 12% of total calories, its composition being 2% saturated and 5% polyunsaturated with a P/S ratio of 2. The mean dietary cholesterol intake was very low, less than 100 mg/day, and the plant sterol intake was high, over 400 mg/day. Carbohydrate comprised 75 to 80% of total calories, mostly from starch. Only 6% of total calories were derived from simple sugars. The crude fiber intake was high, 18 to 21 g/day. Salt consumption was moderately low, 5 to 8 g/day. The daily intakes of calcium, iron, vitamin A, ascorbic acid, thiamin niacin, riboflavin, and vitamin B6 exceeded or approximated the FAO/WHO recommendations. Thus, the simple diet of the Tarahumara Indians, composed primarily of beans and corn, provided a high intake of complex carbohydrate and was low in fat and cholesterol. Their diet was found to be generally of high nutritional quality and would, by all criteria, be considered antiatherogenic.

The interaction of dietary fibers and cholesterol upon the plasma lipids and lipoproteins, sterol balance, and bowel function in human subjects.

To identify any metabolic effects of dietary fiber upon cholesterol metabolism in man, six adult volunteer subjects were fed eucaloric cholesterol-free formula diets, with and without added dietary fiber for two 4-wk periods. A large quantity of dietary fiber was fed, some 60 g of plant cell wall material (or 16 g of crude fiber) derived from corn, beans, bran, pectin, and purified cellulose. This provided about five times the fiber intake of the typical American diet. The addition of fiber to the cholesterol-free diet did not change either the plasma cholesterol level (171+/-21 mg/dl, SEM, to 167+/-18) or the triglyceride (103+/-39 to 93+/-27 mg/dl). The excretion of both endogenous neutral steroids and bile acids were unchanged with fiber (505+/-41 to 636+/-75 mg/day and 194+/-23 to 266+/-47 mg/day, respectively.) However, total fecal steroid excretion was increased 699+/-29 to 902+/-64 mg/day, P < 0.025). With fiber, intestinal transit time was decreased (59+/-9 to 35+/-8 h, P < 0.005), and both the wet and dry stool weights were greatly increased.A second group of six subjects was fed similar diets containing 1,000 mg cholesterol derived from egg yolk. The addition of fiber to the 1,000-mg cholesterol diet did not alter either plasma cholesterol level (233+/-26 to 223+/-36 mg/dl) or triglyceride (102+/-19 to 83+/-11 mg/dl). The excretion of endogenous neutral steroids (618+/-84 to 571+/-59 mg/day), of bile acids (423+/-122 to 401+/-89 mg/day), and of total fecal steroids (1,041+/-175 to 972+/-111 mg/day) were unchanged by fiber. The absorption of dietary cholesterol was not altered when fiber was added to the 1,000-mg cholesterol diet (44.0+/-3.3 to 42.9+/-2.5%). A two-way analysis of variance utilizing both groups of subjects indicated a significant (P < 0.001) effect of dietary cholesterol upon the plasma cholesterol concentration. We concluded that a large quantity of dietary fiber from diverse sources had little or no effect upon the plasma lipids and sterol balance in man in spite of the fact that intestinal transit time and stool bulk changed greatly.

A framework for wound management.

This article looks into four of the most commonly used wound dressing products: Scherisorb (now renamed Intrasite), Kaltostat, Lyofoam and Granuflex. Their characteristics and uses are discussed, and a simple framework for choosing the appropriate dressing for individual wounds has been compiled. The author concludes that there is no 'ideal' dressing which can be used at all the stages of the wound healing process.
