RESUMO

Hairball formation may induce vomiting and intestinal obstruction in predisposed cats. Some insoluble fibres as sugarcane fibre and cellulose can prevent hairball formation. The aim of this study was to evaluate the effect of beet pulp consumption, a moderate soluble and fermentable fibre source, on faecal trichobezoars excretion in adult shorthaired cats fed kibble diets. Eighteen mixed-breed shorthaired cats and three extruded diets were used as follows: a basal diet without added fibre source (PB0-8.8% dietary fibre); BP8-8% inclusion of beet pulp (17.5% of dietary fibre); BP16-16% inclusion of beet pulp (23.8% of dietary fibre). The cats were fed during 31 days and faeces quantitatively collected during three periods of 3 days each (from days 3-5; 15-17; 26-28). Gastrointestinal transit time was determined in the last 3 days of study (from days 29-31). The trichobezoars were separated from faeces, collected, dried and washed in ether for complete removal of all faecal material. The results were submitted to repeated-measure analysis of variance and means evaluated by polynomial contrast (p < 0.05). Beet pulp increased faecal production (p < 0.001) and reduced gastrointestinal transit time (p = 0.003). No alterations were found on trichobezoar faecal excretion, both as considered in number per cat per day of mg per cat per day (p > 0.05). Beet pulp intake did not reduce the number or the size of hairballs eliminated via faeces of shorthaired cats.

RESUMO

Fibre is generally considered to dilute food energy, alter intestinal transit time and promote satiety; however, in cats, conflicting results have been found. In this study, two insoluble fibres were evaluated in four feline diets: control (no added fibre); diet with 10% sugar cane fibre; diet with 20% sugar cane fibre; and diet with 10% cellulose. The experiment was conducted with 32 cats, eight animals per diet, over 42 days: 1-7 for diet adaptation; 8-14 for total collection of faeces for digestibility; 15-17 for fresh faeces collection for fermentation products measurements; 18-20 for gastrointestinal transit time determination; 21 and 37 to evaluate the pattern of food intake; and 22 and 42 to assess satiety. Means were compared by analysis of variance and orthogonal contrasts, and the pattern of food intake was compared by repeated-measures analysis of variance (p < 0.05). The cats exhibited increased food intake after fibre addition to the diets (p < 0.05), achieving similar energy consumption. Cellulose and the two levels of sugar cane fibre reduced nutrient availability and energy digestibility, but only sugar cane fibre reduced fat digestibility (p < 0.05). Faecal output and the number of defecations per day increased with fibre inclusion (p < 0.05). Gastrointestinal transit time did not change with sugar cane fibre inclusion, but it was reduced with cellulose addition (p = 0.032). The pattern of food intake did not change, but cats fed fibre-supplemented diets exhibited greater consumption of a challenge meal, increasing energy intake (p < 0.01) when exposed to a palatable, energy-dense food.

RESUMO

El mesotelioma maligno es una neoplasia originada a partir de las células mesoteliales de las membranas serosas (pleura, peritoneo, pericardio y otros). Es 5 veces más frecuente en la cavidad pleural que en la peritoneal, y puede observarse en ambas por extensión directa a través del diafragma(1). Se presenta el caso de autopsia en una mujer de 83 años, sin antecedentes de exposición al asbesto, oligosintomática, con mesotelioma pleural maligno tipo sarcomatoide, en estadio avanzado (Estadio IV). El mesotelioma es una neoplasia letal, su diagnóstico a veces resulta dificultoso debido al crecimiento lento, las manifestaciones clínicas tardías y el diagnóstico en estadios avanzados. En primer lugar debe descartarse secundarismo y ante clínica e imágenes compatibles debe plantearse su diagnóstico.

Malignant mesotheliomas are tumors derived from mesothelial cells that form the serous membranes. The incidence of mesotheliomas show a rate 5 times greater in the pleural cavity than in the peritoneum; but they can be detected in both, as a result of direct invasion through the diaphragm. A case out from an autopsy is reported, of a 83 years old female patient, with no previous history of exposure to asbestos, oligosymptomatic, with malignant pleural mesothelioma of sarcomatoideal type, at an advanced stage (Stage IV). Malignant mesotheliomas are relatively rare being a highly lethal neoplasia its diagnosis is sometimes difficult because the have a gradual development and growth, with late clinical manifestions, and with diagnosis at an advanced evolutive stages. First of all, secondarism must be discarged, and in presence of compatibles images, its diagnosis must be hypothesized.

RESUMO

Eighty-six alcoholic patients in hospital (average age: 44 years, range: 24-60), were evaluated with the Hamilton Scale for depression and it turned out that 57% were non-depressed alcoholic patients and 43% were depressed alcoholic patients, this being a statistically significant difference. In addition, personal and demographic data was obtained which contributed to the object of the study.
