Anoftalmia clínica bilateral associada à hidrocefalia congênita em cão

A ausência completa do bulbo ocular é muito rara em cães e gatos, enquanto a hidrocefalia é comumente observada como distúrbio congênito em cães de raças miniatura ou braquicefálicas, com menos de um ano de idade. O presente trabalho relata a ocorrência de anoftalmia clínica bilateral associada à hidrocefalia congênita em um cão da raça poodle, sendo este o primeiro relato de caso da associação dessas alterações no Brasil.

Mandibular Movement Restoration Through Bilateral Coronoidectomy by Intraoral Approach

The present study aimed at reporting a clinical and surgical case of bilateral coronoidectomy, using an intraoral approach. The patient is a 26-year-old man, who sought attendance complaining of a gradual reduction of his oral opening in the past 3 years; however, he had an aggravation in the last 2 months. After clinical examination and imaging evaluation, the diagnosis of coronoid process hyperplasia was confirmed, and the surgical treatment was proposed. Under general anesthesia, with nasotracheal intubation guided by a nasofiberendoscope, using an intraoral approach, the bilateral coronoidectomy was performed. In the immediate postoperative period, an increase of the buccal opening measured 29 mm, representing an enhancement of 11 mm, and in the 30th postoperative day, it measured 31.12 mm. During the clinical follow-up period, a reestablishment of the mandibular movements was observed. Therefore, coronoidectomy by an intraoral approach and the physiotherapy performed in the postoperative period were efficient procedures.

Testosterone concentration in a bovine Bos indicus with bilateral varicocele: case report

Um reprodutor bovino, Bos indicus, com varicocele bilateral detectado por palpação e ultra-sonografia foi acompanhado por um período de 24 meses quanto à biometria testicular, valores espermáticos e concentração de testosterona comparados entre as estações do ano e outros animais da mesma espécie. As alterações morfológicas dos defeitos maiores e menores não variaram entre o touro com a patologia e os demais touros, no entanto, durante o verão o touro com varicocele apresentou maior percentual de defeitos totais se comparado aos demais touros da mesma espécie (49,86%±6,9 e 27,91%±2,9). O animal apresentou maior percentual de defeitos maiores no verão se comparado às outras estações do ano. Os achados de necrópsia confirmaram o diagnóstico clínico. Pode-se concluir que esta patologia, caracterizada por trombose nos vasos do cordão espermático, comprometeu a termoregulação determinando degeneração testicular severa. O aumento das concentrações de testosterona sérica sugerem a diminuição da retenção de esteroides nos testículos pelo plexo pampiniforme, a produção espermática estava anormal.

Blindness after laryngectomy and bilateral neck dissection in a diabetic patient: case report

CONTEXTO: O esvaziamento cervical que acompanha a ressecção da lesão primária no tratamento dos tumores malignos das vias aerodigestivas superiores possibilita o surgimento de complicações inerentes a ela ou ao prolongamento do tempo cirúrgico, aumentando os riscos para o paciente. Entre as complicações que podem ocorrer está a amaurose, de incidência rara. RELATO do CASO: Um paciente submetido a laringectomia total e esvaziamento cervical seletivo à esquerda e radical modificado à direita, que evoluiu com amaurose, provavelmente decorrente de hipotensão intra-operatória, com contribuição dos Diabetes Mellitus descompensado e trombose da veia jugular interna à direita. Discutem as possíveis causas, os fatores de risco e os cuidados que devem ser tomados para evitar essa rara, mas tão debilitante complicação.

Epithelial-stromal transition of MMP-7 immunolocalization in the rat ventral prostate following bilateral orchiectorny

Epithelial cells from involuting rat ventral prostate (VP) express Matrilysin (MMP-7) mRNA. Herein, we investigated by immunohistochemistry the NIMP-7 protein location and its association with tissue changes following castration in the VP. Normal and castrated adult male Wistar rats were sacrificed at different times after surgery. VP was examined by immunocytochemistry and immunoprecipitation. Castration promoted a shrinking of prostate ducts with an extensive stromal remodeling. In the VP from normal rats, MMP-7 immunoreactivity was found in epithelial secretory granules. Three days after castration, immunostaining for MMP-7 was found in both the epithelial secretory granules and in the stroma just below the epithelium, mainly at the distal ductal tips. At seven and 21 days after castration, the immunostaining for MMP-7 was found only in the stromal space. Immunoprecipitation confirmed the specificity of the primary antibody by rescuing a pro-enzyme form (28 kDa) in the prostate extracts. The present results suggest that MMP-7 participates in the epithelial-stromal interface remodeling of the ventral prostate during the involution achieved by castration, probably in the degradation of components of the epithelial basement membrane.

THE EFFECTS OF FOREBRAIN MULTIPLE LESIONS ON THE PRESSOR-RESPONSE INDUCED BY BILATERAL CAROTID OCCLUSION IN CONSCIOUS RATS

In the present study, the effects of electrolytic lesions of the anteroventral third ventricle (AV3V) region and of the medial forebrain bundle (MFB) on the pressor response induced by bilateral carotid occlusion (BCO) in conscious intact and aortic baroreceptor-denervated (AD) rats were investigated. In intact control rats, BCO during 60 s produced a pressor response that could be divided into an early response (ER = 50 +/- 3 mmHg) that reachs a peak during the first 20 s and a sustained late response (LR), smaller than ER (32 +/- 2 mmHg), observed during the last 30 s. In intact-innervated rats, AV3V lesion (2 days) reduced ER (22 +/- 3 mmHg) and LR (16 +/- 2 mmHg), whereas the bilateral MFB lesions (6 days) mainly reduced LR (9 +/- 1 mmHg). Rats with simultaneous lesion of both the AV3V region and the MFB showed additional reduction of the ER (15 +/- 3 mmHg), but not LR (11 +/- 1 mmHg) when compared to the effect of MFB lesions alone. Compared to the AV3V lesion alone, LR but not ER was reduced in rats with a double lesion. In sham-lesioned rats, AD induced a significant increase in the pressor response to BCO (ER = 75 +/- 4 mmHg and LR = 65 +/- 3 mmHg) when compared to intact controls. A similar reduction in ER and LR was observed in AD rats after AV3V (ER = 35 +/- 3 mmHg and LR = 40 +/- 2 mmHg) and MFB (ER = 49 +/- 6 mmHg and LR = 41 +/- 5 mmHg) lesions alone or combined (ER = 40 +/- 6 mmHg and LR = 35 +/- 7 mmHg). The results showed that simultaneous lesions of both the AV3V region and the MFB practically abolished the pressor response to BCO. They also suggested that aortic baroreceptor activity plays a significant role in the effects of AV3V and MFB lesions on the pressor response to BCO.

Oral-Facial-Digital Syndrome Type 1: Oral Features in 12 Patients Submitted to Clinical and Radiographic Examination

Objective: To evaluate the oral features in individuals with oral-facial-digital syndrome type 1 (OFD 1), previously diagnosed by the Genetic Sector of the Hospital of Rehabilitation of Craniofacial Anomalies of the University of São Paulo (HRAC-USP).Design: Twelve patients with OFD 1 were examined clinically and radiographically; their medical files were also evaluated.Results: Associated oral malformations were observed in all patients (100%). The most frequent findings were tongue hamartomas, multiple buccal frena, asymmetric lips, asymmetric tongue, and bilateral maxillary gingival swelling. Interestingly, atrophy of the maxillary midline frenum was also observed in all the individuals examined.Conclusions: Several extra and intraoral alterations were observed in patients with OFD 1. The authors suggest the inclusion of atrophy of the maxillary midline frenum as a commonly found characteristic of OFD 1.
