1. Association between bone mineral density and content and physical growth parameters among children and adolescents diagnosed with HIV: a cross-sectional study
ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study con

2. Association of hand grip strength with disease activity, disability and quality of life in children and adolescents with Juvenile Idiopathic Arthritis
Abstract Background: Juvenile idiopathic arthritis (JIA) affects wrist and hand joints leading to decrease hand function and patients’ daily living activities. The assessment of hand grip strength (HGS) in children and adolescents with JIA is of major importance, and the association of HGS with JIA disease activity, disability and quality of life has not

3. Metodologia automática de estimação de idade óssea utilizando análise de forma em radiografias carpais / Methodology automatic bone age estimation using analysis of form in hand-wrist radiographs
The objective of this project is to propose a methodology for estimating the bone age based on a fully automatic system using shape analysis of bone structures. The system aims to assist the diagnosis, supporting the decision of the physicians involved in the process. The methodology is divided into two main blocks. In the first, the middle finger is segment

4. Skeletal maturation assessment of Brazilians using cervical vertebrae analysis / Avaliação da maturação esqueletica na população brasileira por meio da analise das vertebras cervicais
The aim of this study was to evaluate the applicability of the formula developed for Japanese people by Mito et al. (2002) in Brazilians, as well as to establish two new formulas to objectively evaluate skeletal maturation in female and male Brazilian subjects using cephalometric radiographs. The study sample was taken from patient files of the Oral Radiolog

5. Estudo comparativo das densidades dos ossos hamato, capitato e escafóide, por meio de radiografias digitalizadas como um método para estimativa da idade óssea / Comparative study of the densities of hamate, capitate and scaphoid bones by means of digitized radiographs as a method to estimate bone age
Objectives: To evaluate the radiographic density of three carpal bones (hamate, capitate and scaphoid bones) in male and female patients aged 7 to 18 years by means of an image-editing software (Adobe Photoshop - 6.0®). Methods: Readings of gray intensities of each image selected in each bone and drawing of a histogram referring to the values of number of p

6. Study of the relationship between the stages of skeletal maturation by means of hand-wrist radiography and cervical vertebrae in lateral cephalograms. / "Estudo da relação entre os estágios de maturidade óssea avaliados em radiografias de mão e punho e das vértebras cervicais em telerradiografias em norma lateral"
O objetivo neste estudo foi avaliar a possível relação entre os estágios de maturidade óssea avaliados em radiografias de mão e punho e das vértebras cervicais em telerradiografias em norma lateral, em indivíduos com idade média de 13 anos e 6 meses e desvio padrão de 2 anos e 3 meses (variando de 8 anos e 6 meses a 16 anos e 11 meses). A casuísti

7. Quantitative microfocal radiography accurately detects joint changes in rheumatoid arthritis.
Microfocal radiography, producing x5 magnified images of the wrist and hands with a high spacial resolution (25 microns) in the film, permitted direct measurement of erosion area and joint space width in patients with rheumatoid arthritis. The magnitude of errors relating to direct measurement, repositioning the wrist and hand on successive x ray visits, rep

8. Erosion number and area progression in the wrists and hands of rheumatoid patients: a quantitative microfocal radiographic study.
Microfocal radiography has been used to evaluate the relation between erosion number and erosion area in the hands and wrists of 51 patients with early to moderately advanced rheumatoid arthritis. The hands of these patients showed different patterns of erosion progression, in terms of the relation between changes in number and area, and included those showi
