RESUMO
Three new points of view were reported in this study:1.Found out the distribution of KaschinBeck disease (KBD) in Tibet,the complexity of bone disease composition,and the types of osteopathy coexisted which need to be identified;2.The clinical symptoms of KBD in Tibet were significantly different from those in other areas of our country;3.The new clinical subtypes of KBD were found in Tibet,which had humeral shortness and short stature,but with normal hands and feet.This discovery made us understand KBD more profoundly and comprehensively,and promoted the research and prevention work of KBD.
RESUMO
Chondrodysplasia punctata is a rare congenital syndrome caused by a peroxisomal dysfunction. Chondrodysplasia punctata is classified into four main types-Coradi-Hunermann's type, rhizomelic type, X-linked dominant form and X-linked recessive form. A male patient with this condition was born at 39 weeks gestation, the pregnancy being complicated by polyhydroamnios, breech presentation, and anomalies of congenital limbs. At delivery, there was no activity and no initial crying. Physical examination revealed a flat nose, a short neck, scaled ichthyolytic skin, and bilaterally symmetrical shortening of the upper and lower extremities. Choromosomal analysis revealed a 46, XY karyotype. Radiologic examination disclosed stippling of the cartilage on the epiphyseal regions of the long bones, paravertebral regions, carpal bones and tarsal bones. In additions, a chest x-ray showed right pneumothorax. Chest and endotracheal tubes were inserted. However, the patient died due to respiratory failure at 19 days of life. We report a case of rhizomelic type of chondrodysplasia punctata assocoated with pneumothorax with a brief review of the related literatures.
