Guizhou semi-fine wool sheep are affected by a disease, characterized by emaciation, lameness, stiffness in the gait, enlargement of the costochondral junctions, and abnormal curvature in the long bones. The objective of this study was to determine possible relationships between the disease and mineral deficiencies. Samples of tissue and blood were collected from affected and unaffected sheep. ...

lii previous papers of this series (Trueta and Amato 1960, Trueta and Trias 1961) experiments were described in which the effect of a decrease or total suppression of the blood to either one or other side of the epiphysial cartilage was investigated. These experiments showed that the only source of nourishment of the growth cartilage was the blood of the epiphysial vessels. It was also demonstr...

A 50-year-old postmenopausal woman presented with a 9month history of a lump on her left anterior chest wall in the region of the 2nd and 3rd costochondral junction. She reported the mass changed in size and at times felt soft and fluctuant. It intermittently swelled, causing her local discomfort followed by periods of spontaneous regression, which would be accompanied by inflammation localized...

Rib grafts in facial plastic surgery are becoming more frequently used. Small animal models, although not ideal may be used to emulate costal cartilage-based procedures. A surgical characterization of this tissue will assist future research in the selection of appropriate costal segments, based on quantitative and qualitative properties. The objective of this study is to assess the surgical ana...

The importance of the mandibular condyle for craniofacial growth and development has often been discussed. Several theories on craniofacial morphogenesis have been proposed, of which some define the mandibular condyle as an important growth centre (Baume, 1961; van Limborgh, 1972); others consider it as an organ without independent growth potential that is mainly adapting to the function of sur...

DIAGNOSTIC STANDARDS There is insufficient evidence to support diagnostic standards. GUIDELINES In children who have experienced trauma and are alert, conversant, have no neurological deficit, no midline cervical tenderness, and no painful distracting injury, and are not intoxicated, cervical spine x-rays are not necessary to exclude cervical spine injury and are not recommended. In childr...

INTRODUCTION Intracranial chondromas are extremely rare intracranial tumours that usually arise from the skull base synchondrosis. Exceptionally, they may grow from cartilage rests within the dura mater of the convexity or the falx. They may be part of Ollier's multiple enchondromatosis or Maffuci's syndrome. We describe the case of a young male diagnosed of Noonan's syndrome that underwent res...
