Hiperadrenocorticismo em cães: revisão

Hyperadrenocorticism is a relatively common endocrinopathy in dogs, which is associated to an excessive production or administration of cortisol. The most affected breeds are Poodles, Teckels, Boxers, Boston Terriers and Beagles. The clinical signs most commonly observed are polyuria, polydipsia, polyfagia, panting, distended abdomen, endocrine alopecia, muscular weakness and lethargy. Laboratorial abnormalities include stress leukogram, increase in alkaline phosphatase and alanine aminotransferase activities, hypercholesterolemia, lipemia, hyperglycemia and hyposthenuria. The preferred essay to evaluate adrenal gland function is the low-dose dexamethasone suppression test, whereas the most used treatments include mitotane and trilostane. The objective of this paper is to review hyperadrenocorticism in dogs, because this disease is relatively common in small animal clinics and has many long-term complications.

Avaliação ultrassonográfica abdominal modo-B em cães e gatos filhotes: revisão de literatura

In veterinary medicine, the same clinician usually follows an animal from birth to old age, whereas in human medicine different specialists are required. It is therefore essential that veterinarians know the normal imaging, biochemical, hematological and physical exam values for younglings, which differ significantly from those of adults of the same species. Abdominal radiographies of young animals are poorly defined due to differences in tissue constitution in relation to adults. These same factors, however, substantially improve sonographic images of the region. Nonetheless, the interpretation of B-mode sonographic findings in puppies is difficult due to the lack of information about the normal parameters in this phase of life. The objective of this study was to compile information about peculiarities of abdominal B-mode ultrasonography in puppies and kittens.

Termofisiolofia da vespa Polybia (Trichothorax) ignobilis (Haliday, 1836) (Hymenoptera, Vespidae, Epiponini) durante a atividade de forrageamento

Many social wasps are known to use thermogenesis to warm up their flight muscles and are therefore able to forage under a broad range of ambient temperatures. However it is uncertain whether there exists a possible relation between ambient temperature and thermogenic capacity for tropical species, as we lack studies focusing on these species. Therefore, we examined the use of this mechanism in the neotropical Epiponini wasp Polybia ignobilis. More specifically, we used a thermographic camera to obtain data of the surface temperatures of three body regions (head, thorax and abdomen) of wasps during foraging activities (pre-flight, flight and post-flight) in cold [initial pe- riod of foraging activity: TAM : 15 − 20◦C] and warm [final period of foraging activity: TPM : 30 − 35◦C] conditions. Thorax temperature (Tth) was always higher than head (Th) and abdomen temperature (Tabd). In general, the lowest body temperatures were observed during the pre-flight period, while the highest values occurred upon the return of the wasps from the foraging flight. Except for the pre-flight period, Tth was always higher than Tabd, indicating that heat generated at the thorax was preferentially directed to the cephalic region. Therefore we confirmed the use of thermogenesis by a neotropical social wasp, although its magnitude was found modest compared to temperate species, which suggests a link between thermal environment and thermogenic capacity. We also showed that P. ignobilis modulates heat production as a function of ambient temperature (TA), maintaining a greater temperature difference (Tbody − TA) at cooler temperatures. Finally, we identified the cephalic region of wasps as an important route for the dissipation of the heat generated during flight
