Malassezia spp. dermatitis, a rare disorder in cats, has previously been associated with immune suppression and internal malignancies. This study evaluates the presence and importance of Malassezia spp. in feline biopsy specimens submitted for histopathological examination. Five hundred and fifty haematoxylin and eosin-stained skin biopsy specimens received for histopathological examination between January 1999 and November 2000 were reviewed. Fifteen (2.7%) submissions contained Malassezia organisms in the stratum corneum of the epidermis or follicular infundibulum. Eleven of 15 cats presented with an acute onset of multifocal to generalized skin lesions. All 11 cats were euthanized or died within 2 months of the onset of clinical signs. Seven cats had dermatopathological changes and clinical signs supportive of paraneoplastic alopecia, and three cats had an interface dermatitis suggestive of erythema multiforme or thymoma-associated dermatosis. Histopathological changes were nonspecific in one cat that was euthanized 2 weeks following onset of severe pruritus and alopecia. In three cats, Malassezia spp. were found in localized sites (two chin, one footpads) and appeared inconsequential to their overall health status. One cat had Malassezia spp. in association with cutaneous demodicosis. These findings suggest that Malassezia yeast in dermatopathological specimens from multifocal or generalized lesions should prompt a thorough clinical work-up for internal neoplasia.

To assess the safety of grape seed extract with less than 5.5% catechin monomers (IH636), 4 groups of male and female Sprague-Dawley rats were provided grape seed extract in the diet at levels of 0 (control), 0.5, 1.0, or 2.0% for a period of 90 days. All animals survived the duration of the study, and no significant changes in clinical signs, hematological parameters, organ weights, ophthalmology evaluations, or histopathological findings were observed. A significant increase in food consumption was observed in male and female rats provided the grape seed extract diets compared to that of the control rats, especially in male rats consuming 2.0% grape seed extract. This effect was not accompanied by increases in body weight gains. Grape seed extract appeared to increase the insoluble fraction of the diet. Male rats in the high-dose group exhibited decreased serum iron levels and decreased serum iron/total iron binding capacity ratio compared to those of the controls, although all values were within historical ranges for Sprague-Dawley rats. In conclusion, administration of the grape seed extract IH636 to male and female Sprague-Dawley rats in the feed at levels of 0.5, 1.0, or 2.0% for 90 days did not induce any significant toxicological effects.

This study was designed to measure treatment side-effects and quality of life (QL) of 47 nonmetastatic breast cancer patients subjected to a dose-intensity increase while receiving a sequential high dose chemotherapy (doxorubicin+cyclophosphamide - 4 cycles). The dose-intensity increase was obtained by shortening the length of cycles from 21 to 14 days. Treatment side-effects were self-assessed in terms of frequency and associated distress in cycles 1 and 3 by using a specific side-effect self-report questionnaire (19 items). Multidimensional QL measurement was performed at inclusion and before the start of cycles 2 and 4, by using the EORTC QLQ-C30. Pain was evaluated by patients on a visual analogue scale at the same times as QL evaluation. Patients' self-ratings indicated that the total number of symptoms, the number of symptoms rated by patients as quite or very distressing, and symptom frequency were comparable whatever the length of cycle. Overall, although underestimating most patients' symptoms, physicians' reports provided similar results. However, analysis of multidimensional QL showed that, in comparison to standard administration of 4 cycles of 21 days, there was a more significant deterioration of the QLQ-C30 global QL score ( P=0.01) at the second cycle of chemotherapy and of the physical functioning score ( P=0.02) at the fourth cycle when the cycle length was reduced. This study, although limited by a small patient cohort, has shown that shortening cycles to increase dose intensity had relatively few consequences on adverse treatment effects but a highly negative impact on patients' quality of life.
