Necrotizing fasciitis is a rare dermatopathy that promotes subcutaneous tissue damage, associated to substantial morbidity and mortality if treatment is not initiated at the beginning of the condition. The objective of the present study is to report the occurrence of two cases of necrotizing fasciitis, one in a miniature female Pinscher and the other one in a female Poodle, both attended at the Veterinary Hospital of FMVZ/Unesp-Botucatu. The animals presented ulcerated, erythematous lesions with secretion and points of necrosis along fascial planes. Bacterial culture was positive for Streptococcus spp. The animals were treated with enrofloxacin, associated to topical cleaning of the lesions with saline solution and triclosan-based soap and rifampicin spray. Both animals presented total remission of lesions after approximately 15 days of treatment. The present report aims to alert veterinary clinicians to the severity of Streptococcus spp infections.

The electrocardiogram (ECG) is an important tool used in the diagnosis of cardiac arrhythmias, since it gives the graphic representation of depolarization and repolarization processes of the cardiac muscle. This study allows recording the electrical activity of myocardial cells and the underlying differences in electric potential: the magnitude of this difference is measured in millivolts (mV), and its duration is measured in seconds. The ECG is indicated when an irregular rhythm is detected during physical examination, such as bradycardias, tachycardias or arrhythmias that are not secondary to breathing, in animals with a history of syncope or weakness, for monitoring the effectiveness of antiarrhythmic therapy, in cases of putative pleural or pericardial effusion, and also in systemic diseases that lead to arrhythmia. For a reliable assessment, the ECG must be evaluated in conjunction with findings from the physical examination and clinical signs of each patient.

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.

[ES] Introducción: A pesar de exhibir diferencias histológicas con el proceso en humanos, la hiperplasia benigna de prostáta (HBP) inducida por hormonas en perros representa el modelo más utilizado actualmente para la evaluación de tratamientos. Objetivos: El objetivo del presente estudio es determinar el momento óptimo para la realización de un ensayo terapéutico en este modelo. Material y métodos: En el estudio se utilizaron 6 perros beagle, machos mayores de un año, a los que se administró una combinación de hormonas, 17b-estradiol y 5a-androsteno 3a 17b-diol, en días alternos durante 3 (grupo 1, n = 3) o 5 meses (grupo 2, n = 3). Se realizaron seguimientos ultrasonográficos mensuales, con determinación del tamaño prostático. A los 5 meses se procedió al sacrificio de todos los animales y el estudio histológico de las glándulas prostáticas. Resultados: Todos los animales desarrollaron una HBP, con un volumen prostático que aumentaba con el tiempo de administración hormonal (r = 0,910), evidenciándose en todos los estudios ecográficos hasta el tercer mes un aumento significativo de tamaño frente al estudio anterior. El tamaño prostático disminuyó considerablemente en el grupo 1 al retirar la hormonoterapia, al tiempo que en el grupo 2 continuó aumentando. Los animales del grupo 1 apenas evidenciaron signos histológicos de HBP, frente a los del grupo 2, que presentaron una clara hiperplasia del epitelio glandular. Conclusiones: La administración de una combinación de hormonas esteroides es efectiva para inducir hiperplasia de próstata en perro, si bien ésta desaparece en el momento que se retira la hormonoterapia. Para utilizar este modelo en estudios experimentales, se deben administrar hormonas al menos durante 3 meses antes de la actuación terapéutica, y continuar durante todo el ensayo
