Background: Spondyloepiphyseal dysplasia-brachydactyly and distinctive speech (SED-BDS) is a syndrome characterized by short stature, disproportionately short limbs, peculiar face, thick and abundant hair, high-pitched and coarse voice, small epiphyses, brachymetacarpalia, brachymetatarsalia and brachy-phalangia of fingers and toes, small pelvis and delayed carpal bone age, among other features. Case Report: We report a Brazilian patient with father, brother and sister presenting with the same typical features of the syndrome. Clinically, he showed disproportionately short stature, rhizo-meso-acromelic shortness of the extremities, short hands and feet, a peculiar distinctive high-pitched voice, peculiar facies, and other features already reported as characteristic of this syndrome. Radiographic fndings included shape anomalies of the vertebral bodies such as cuboid-shaped vertebral bodies, mild scoliosis, short and broad tubular bones, brachymetacarpalia, brachymetatarsalia, and brachy-dactyly, lumbar hyperlordosis, generalized osteopenia, and hypoplastic iliac wings. Conclusions: Few cases have been described, as this is a rare skeletal dysplasia. This paper describes a new familial case of SED-BDS. © The American Journal of Case Reports.

A new species of miniaturized froglet (genus Brachycephalus) is described from Morro Prumirim in the municipality of Ubatuba, São Paulo, southeastern Brazil. Specimens were collected from the leaf litter at approximately 800 m above sea level. The new species is distinguished from all its congeners by the combination of the following characters: snout-vent length 8.7-13.4 mm; skin on head and dorsum with dermal ossification; general color orange, with a narrow brownish vertebral stripe and belly without spots; and skull, spinal processes of sacral and pre-sacral vertebrae, and process of the fourth vertebra hyperossified. Canonical variates analysis of linear body measurement demonstrates that the new species is easily discriminated from other Brachycephalus species with which it shares an intermediate condition of hyperossification. © 2012 by The Herpetologists League, Inc.

A prática regular de exercícios físicos previne e combate várias doenças ao longo do tempo, destacando-se como excelente ferramenta terapêutica para o tratamento de lesões no sistema nervoso central (SNC). Após uma transecção (completa ou incompleta/hemissecção) da medula espinhal, células gliais reativas secretam substâncias inibitórias à regeneração axonal como, por exemplo, as moléculas de proteoglicanas de sulfato de condroitina (PGSCs) que exercem papel importante na formação de uma barreira físico-química, chamada cicatriz glial, que impede o crescimento dos axônios danificados pela lesão. Pesquisas que envolvem modelo experimental de lesão da medula espinhal e reabilitação por exercício físico têm obtido promissores resultados. No entanto, os mecanismos fisiológicos e moleculares pelos quais promovem esses resultados positivos ainda são pouco conhecidos. O objetivo do presente trabalho foi analisar a recuperação da função motora da pata posterior após protocolo de exercício físico voluntario em modelo experimental de hemissecção da medula espinhal e investigar dois mecanismos moleculares envolvidos na recuperação funcional: a degradação de PGSCs nas redes perineuronais e acetilação de histonas. Para isso, vinte e quatro (24) ratos da linhagem Wistar (Rattus novergicus) foram utilizados e separados em 3 grupos (controle, treinados e não treinados). Com exceção do grupo controle, todos os animais foram habituados a rodas de corridas e em seguidas foram submetidos a uma cirurgia experimental de hemissecção da medula espinhal, na altura da 8a vertebra torácica. Nossos resultados demonstraram que o exercício voluntário em rodas de corrida após lesão experimental da medula espinhal promoveu recuperação da função motora da pata posterior afetada, porém não observamos diferenças qualitativas na acetilação de histonas e degradação de PGSCs entre os grupos.

Schistosomus reflexus (SR) is a rare and fatal congenital anomaly, primarily observed in ruminants, presenting fetus with dorsiflexion of the vertebral column, exposure of thoracic and visceral organs, and scoliosis. A caesarian was performed on a Dorper sheep on a farm in Botucatu-SP and according to the general characteristics and findings observed in the necropsy of the fetus it was an SR case. The radiography indicated a marked ventro-dorsal deviation of the thoracolumbar column segment and deformity of the ribs. On the computed tomography the integrity of the bones and organs were detected, except for the absence of a lumbar vertebra. No data were available in the literature for SR diagnosis in sheep by image, so radiographic and tomographic exams of the fetus were done.

Based on the concept that horses have balanced symmetry between its anatomical regions, the aim of this study was to introduce a method of assessing the balance of equines through body proportions. Altogether twelve linear measurements, using metric tape, were measured in 234 horses Quarter Horses for evidence of barrel racing. From these measurements were built nine body proportions, each one given by the ratio of two specific measures, and the effects of sex, weight, age and degree of blood on the balance were evaluated. To check the significance tests we used the F statistic, considering P<0.05. It was found that the linear measurements ML2, ML3 and ML5 were mainly responsible for the disproportionality of the horses evaluated. The effect of sex was significant (P<0.05) for four proportions (R1, R3, R4 and R9) and females were more distant from the concept of balance than males.
