RESUMEN

The impact of the Antarctic Ozone Hole Influence over Southern Brazil in October 2015 was analyzed using daily mean data of the Total Column Ozone (TCO), Ultraviolet Index (UVI) and Radiative Cloud Fraction (RCF) from the Ozone Monitoring Instrument satellite instrument. Vertical profiles and fields of ozone content and Potential Vorticity available from the European Centre for Medium-Range Weather Forecast reanalysis, air masses backward trajectories from the HYbrid Single-Particle Lagrangian Integrated Trajectory model and channel 3 water vapor images from the Geostationary Operational Environmental Satellite GOES-13 were also analyzed. The five identified events showed an -7.4±2.3% average TCO reduction, leading to an +16.6±54.6% UVI increase even with a predominance of partly cloudy days. Other impacts were observed in the ozone profiles, where the most significant anomalies occurred from 650 K reaching 1.2 ppmv at the 850 K level. In the ozone fields at 700 K, the presence of a polar origin tongue was observed causing negatives anomalies between -0.2 and 0.4 ppmv in a transient system format forced with eastward-traveling Rossby waves passing through the Southern of Brazil and Uruguay.

RESUMEN

We present the case of a five-year-old intact mixed breed male dog with hemorrhagic prostatic cysts. The patient presented with hematuria, dysesthesia, and pain on abdominal palpation. Abdominal ultrasound, hematology, urinalysis, and biochemical evaluation tests were subsequently conducted. Laboratory tests revealed cloudy urine with bacteria, and countless red blood cells. On ultrasound examination, the prostate was severely enlarged, with heterogeneous and reduced parenchyma, surrounding a large cavity filled with anechoic material with moderate cellularity. The urinary bladder was markedly distended and had a round, hypoechogenic structure in the lumen. The patient was hospitalized and had significant, irreversible worsening of the clinical symptoms and died. Subsequently, necropsy of the patient was performed and a histopathological diagnosis of benign prostatic hyperplasia associated with the presence of a prostatic hemorrhagic cyst, prostatitis, and chronic cystitis with an intraluminal blood clot was made. To the best of our knowledge, this is the first report to describe the occurrence of a hemorrhagic cyst in a canine prostate, thus bringing important information from clinical and imaging findings to the veterinary routine.

Apresentamos o caso de um cão macho de cinco anos de idade sem raça definida com cisto prostático hemorrágico. O paciente manifestava hematúria, disquesia e dor à palpação abdominal. Foram realizadas ultrassonografias abdominais subsequentes, hematologia, urinálise e testes de avaliação bioquímica. Os testes laboratoriais revelaram urina turva com bactérias e inúmeros glóbulos vermelhos. No exame ultrassonográfico, a próstata estava severamente aumentada, com parênquima heterogêneo e reduzido, circundando uma grande cavidade cheia de material anecoico com celularidade moderada. A bexiga urinária estava marcadamente distendida e tinha uma estrutura redonda e hipoecogênica no lúmen. O paciente foi internado e teve um agravamento significativo e irreversível dos sintomas clínicos e veio a óbito. Subsequentemente, foi realizada a necropsia do paciente e foi feito o diagnóstico histopatológico de hiperplasia prostática benigna associada à presença de um cisto hemorrágico prostático, prostatite e cistite crônica com um coágulo sanguíneo intraluminal. Tanto quanto sabemos, este é o primeiro relatório descrevendo a ocorrência de um cisto hemorrágico numa próstata canina, trazendo assim informações importantes dos resultados clínicos e de imagem para a rotina veterinária.

RESUMEN

Traumatismos causados com espinho de porco espinho são comuns em cães. Entretanto, estes espinhos não são inertes podendo carrear bactérias e outros micro-organismos. A indicação frente à essa situação é a remoção de todo o material sempre que possível. Ultrassonografia, tomografia computadorizada e ressonância magnética possuem valor significativo no diagnóstico e localização de corpos estranhos não visíveis no exame físico. O objetivo deste relato de caso é descrever a presença de um corpo estranho linear na região intraocular de um cão macho, três anos de idade, sem raça definida. O animal deu entrada no serviço clínico de um Hospital Veterinário com apatia e histórico de contato com porco espinho há trinta dias. Observou-se secreção ocular e olhos recobertos pela terceira pálpebra. Nesta ocasião, foram retirados espinhos de ouriço na cavidade oral e o animal foi liberado. Entretanto, o paciente retornou 40 dias com piora do quadro oftalmológico. Foi realizado exame ultrassonográfico transpalpebral que detectou uma estrutura linear hiperecoica medindo aproximadamente 1,47cm com sobra acústica evidente e conteúdo anormal de ecogenicidade mista na câmara vítrea. Encaminhado para enucleação transpalpebral que possibilitou confirmar o diagnóstico e identificar o objeto. Após a remoção cirúrgica o paciente apresentou melhora clínica significativa e recebeu alta médica em 14 dias.

Trauma caused by porcupine thorns is common in dogs. However, these spines are not inert and can carry bacteria and other microorganisms. The advice given this situation is the removal of all material whenever possible. Ultrasonography, computed tomography and magnetic resonance have significant value in the diagnosis and localization of foreign bodies not visible on physical examination. The purpose of this case report is to describe the presence of a linear foreign body in the intraocular region of a three year old, male dog, of mixed breed. The animal was admitted to the clinical service of a Veterinary Hospital with apathy and a history of contact with a porcupine within thirty days. Eye discharge and eyes covered by the third eyelid were observed. On this occasion, hedgehog spines were removed in the oral cavity and the animal was released. However, the patient returned 40 days later with worsening of the ophthalmic condition. A transpalpebral ultrasound examination was performed, which detected a hyperechoic linear structure measuring approximately 1.47cm with evident acoustic leftovers and abnormal mixed echogenicity content in the vitreous chamber. The dog was referred for transpalpebral enucleation, which made it possible to confirm the diagnosis and identify the object. After surgical removal, the patient showed significant clinical improvement and was discharged within 14 days.
