Espinha bífida aberta em bovino: primeiro relato no estado de Minas Gerais / Open spina bifida in calf: first report in Minas Gerais state, Brazil

Relatou-se um caso de espinha bífida aberta em uma bezerra de seis dias de idade que apresentava decúbito lateral permanente, pescoço em posição de opistótono, membros torácicos estendidos, impotência funcional dos membros pélvicos e fístulação na região lombar. Todos os achados clínicos, radiográficos e necroscópicos, descritos neste trabalho, são compatíveis com um quadro de espinha bífida aberta, sendo este o primeiro relato no estado de Minas Gerais.

A case of open spina bifida is reported in a six day old calf which presented permanent lateral decubitus, opisthotonus neck position, stretched forelimbs, non-functional impairment of the hindlimbs and fistula in the lumbar region. All clinical, radiographic and necropsy finds described in this work are consistent with an open spina bifida case. This is the first case report in Minas Gerais State, Brazil.

Polidactilismo unilateral incomum em equino: relato de caso / Unusual unilateral polydactylism in a horse: a case report

A polidactilia é um defeito genético caracterizado pela duplicação parcial ou completa de um dígito. Estudos em humanos, bovinos, cães e gatos indicam que um gene autossômico dominante de penetração incompleta é o responsável por essa alteração. A polidactilia é rara em equinos e, nessa espécie, sua causa ainda não foi esclarecida. Entretanto, quando ocorre, está relacionada à má formação congênita da falange. Este trabalho descreve, por meio da observação de exames físico, radiográfico e ultrassonográfico, a ocorrência de polidactilia unilateral, com características incomuns, em um equino de nove anos de idade. O animal, com um histórico de claudicação intensa, apresentava, desde o nascimento, divisão completa do dígito do membro torácico direito, com simetria entre as duas porções distais. Ao exame radiográfico, identificou-se a presença de dois dígitos separados e de dimensões semelhantes, sendo esta uma manifestação incomum de polidactilia na espécie equina.

Polydactyly is a genetic disorder characterized by partial or complete duplication of a digit. Studies in humans, cattle, dogs and cats indicate that an autosomal dominant gene of incomplete penetrance is responsible for this change. Polydactyly is rare in horses and its cause remains unclear. However, when it occurs it is related to congenital malformation of the phalanx. This paper describes, through the observation of physical, radiographic and ultrasound finds, the occurrence of unilateral polydactyly, with unusual features in a nine year old horse. Since birth, the animal, which had a history of severe lameness, had complete division of the digit of the right forelimb, with symmetry between the two distal portions. The radiographic examination identified the presence of two separated digits with similar size, which is an unusual manifestation of polydactyly in the equine species.

Apolipoprotein B-100/Apolipoprotein A-I Ratio is on Useful Indicator for Coronary Artery Disease in Koreans

BACKGROUND AND OBJECTIVES: Little is known about the relationship between the apolipoprotein (apo) B-100, or the apo B-100/apo A-I ratio, and coronary artery disease (CAD). The aim of this study was to investigate this association. SUBJECTS AND METHODS: Our study was carried out on 194 patients who had undergone elective coronary angiography (CAG), but had received no lipid-lowering medication. Patients with acute myocardial infarction were excluded. Stenosis of >or=50% in 1 or more coronary arteries was classified as CAD (+). RESULTS: HDL-C and apo A-I were significantly higher in females than in males (p=0.009 and 0.036). In our population we found that the apo A-I, HDL-C and the apo B-100/apo A-I ratio were significantly related to CAD (p=0.001, 0.006, and 0.007 respectively). In the male group (n=111), the apo B-100/apo A-I ratio was the only parameter statistically significant to CAD after correcting for age, diabetes mellitus and hypertension. Whereas, in the female group (n=83), the apo B/apo A-I ratio, apo B-100/apo A-I ratio, apo B-100, nonHDL-C, triglyceride, apo B, total cholesterol and low-density lipoprotein cholesterol were all significantly related to CAD (p=0.002, 0.003, 0.003, 0.007, 0.007, 0.009, 0.012 and 0.012 respectively). Of these parameters only the apo B-100/apo A-I ratio was significantly related to CAD in both female and male group. CONCLUSION: The apo B-100/apo A-I ratio is an useful indicator for discriminating between CAD (+) and CAD (-).
