[Results of the experimental repair of osteochondral lesions in a pig model using tissue engineering].

Objective: To repair experimental osteochondral knee lesions in pigs using tissue engineering.

Material And Methods: Eight 40-kg pigs underwent surgery. Cartilage and periosteal biopsies of their control knee were taken.

[Congenital cervical vertebral dysmorphism. Syndromatic integration through radiological clinical correlation].

Cervical spine dysmorphisms (CSD) occurs in an heterogeneous group of patients unified by the presence of congenital defects result from malalignment, formation or segmentation of the cervical spine; generating disability. This problem requires comprehensive evaluation of patients with scoliosis diagnosis, correlating clinical and radiological findings and the presence of numerous abnormalities of other systems in order to give an opportunely syndrome diagnosis and multidisciplinary management of this patients with the aim to give them an integral rehabilitation treatment increasing their quality of life. In this study we described clinical and radiological findings in children with CSD diagnosis.

[Diagnosis of Krabbe's leukodystrophy by transmission electron microscopy. Case report].

Krabbe's leukodystrophy is a rare hereditary disease in Mexico. For that reason we report the case of an 11-year-old child. Ultrastructural studies of sural nerve biopsy specimen are described.
