1. Novos métodos para estimativa da idade óssea baseados no processamento de imagens radiográficas da mão / New methods to bone age estimation based on hand radiographic image processing
Bone age (or skeletal maturity) assessment using a radiograph of the left hand is a common procedure in pediatric radiology. The methods most widely used for bone age determination presents high complexity degree for estimation, usually performed by radiologist and this task is extremely complex and time-consuming producing results with high charge of person

2. Higiene das mãos: comparação da eficácia antimicrobiana do álcool - formulação gel e líquida - nas mãos com matéria orgânica. / Hand hygiene : antimicrobial activity comparison of three alcoholic produts - gel and liquid - in hands with organic material.
Hand hygiene is considered the most important measure to reduce the transmission of nosocomial pathogens in health care settings. Because alcohol has excellent antimicrobial activity, requires less time, results in less skin irritation and does not require proximity to a sink, is the preferred agent for hand hygiene. In the face of scientific evidence, there

3. Diaphysial nutrient foramina in human metacarpals and metatarsals.
728 metacarpals and 691 metatarsals of unknown sex, and 120 metacarpals and metatarsals, each of known sex, were studied for the number, position, direction and symmetry of the diaphysial nutrient foramina. It was found that, in general, these bones had one nutrient foramen which was situated in the middle third of the shaft (over 90%). Few bones had no fora

5. Torsion in metacarpal bones and bilateral asymmetry.
A comparison of the relative position of the dorsoventral axes of the bases and heads of the metacarpal bones shows that these do not lie in the same plane, and that torsion can therefore be said to exist in these bones. Torsion is such that the heads of the second and third metacarpals appear to be rotated laterally relative to the base, whereas the heads o

6. An adult female with spondyloepiphyseal dysplasia tarda
We report a sporadic adult female with a distinctive variety of spondyloepiphyseal dysplasia tarda characterised by universal platyspondyly, short metacarpals, short metatarsals, genu valgum, mild thoracic kyphoscoliosis, and severe generalised epiphyseal distortion with premature osteoarthrosis.

7. Classification and identification of inherited brachydactylies
A search for patterns of malformation in the brachydactylies has resulted in new ways to identify the different types. Type A-1 can be characterised by a proportionate reduction of the middle phalanges. Type B is thought to be an amputation-like defect. In type C the fourth middle phalanx is usually the longest, and type E (Riccardi and Holmes, 1974) is char

8. A family with diaphyseal aclasis and peripheral dysostosis.
Autosomal dominant inheritance of a type of peripheral dysostosis occurred in a family with diaphyseal aclasis. The features of their type of peripheral dysostosis were short limbed short stature, normal intelligence, very stubby fingers, flat face and nose, shortened metacarpals and terminal phalanges, thickened beaten-copper skull vault, and advanced skele

9. Pseudopseudohypoparathyroidism and spinal cord compression.
A 42 year old Greek male with pseudo-pseudohypoparathyroidism presented with difficulty in walking and with lower limb weakness. His physical signs included short stature, thick neck, short fourth metacarpals and metatarsals, and a spastic paraparesis. Serum calcium and phosphate and parathyroid concentrations were normal. Myelography demonstrated compressio

10. Axial skeleton homeosis and forelimb malformations in Hoxd-11 mutant mice.
The Hoxd-11 gene was disrupted by homologous recombination in embryonic stem cells. We found that Hoxd-11-/- mutant mice are viable and display homeotic transformations of their sacral vertebrae, while their forelimbs present abnormalities of some metacarpals and of the first row of carpal bones. These results are discussed in the light of current models of

11. Retinitis pigmentosa, metaphyseal chondrodysplasia, and brachydactyly: an affected brother and sister.
A brother and sister, children of normal parents are described. They had retinitis pigmentosa, causing near-blindness as a result of very narrow fields of vision, associated with metaphyseal chondrodysplasia and marked shortening of the metacarpals and terminal phalanges. Autosomal recessive inheritance is suggested with a common biochemical cause for all th

12. Schizophrenia and mental retardation in an adult male with a de novo interstitial deletion 9(q32q34.1).
A 28 year old man with mental retardation and therapeutically controlled schizophrenia was found to have a de novo interstitial deletion in the long arm of a chromosome 9 (46,XY,del(9)(q32q34.1). Additional phenotypic abnormalities included short stature, a short webbed neck with a low posterior hairline, dysmorphic facies, a narrow palate with an inverted V
