Crianças com acondroplasia que recebem GH em alguns casos demonstram melhora do crescimento, no entanto, foi relatado o deslocamento atlanto-occipital, embora não seja comum, em outras palavras, é muito raro na literatura médica. A possibilidade de crescimento cerebral anormal e sua relação com formas cranianas anormais indicam que o GH não é uma possibilidade estabelecida para tratamento desta condição nosológica.
THE GROWTH AND THE LOW HEIGHT IN CHILD, CHILDREN AND YOUTH INCLUDING ADOLESCENCE; THE SKELETAL DYSPLASIA.
SKELETAL DYSPLASIAS: THERE ARE MORE THAN 100 TYPES OF GENETIC ORIGIN OF SKELETAL DYSPLASIA (OSTEOCHONDRODYSPLASIA). PHYSIOLOGY-ENDOCRINOLOGY-NEUROENDOCRINOLOGY-GENETICS-ENDOCRINE-PEDIATRICS (SUBDIVISION OF ENDOCRINOLOGY): DR. JOÃO SANTOS CAIO JR. ET DRA. HENRIQUETA VERLANGIERI CAIO.
Often, they are observed at birth due to the presence of shortened limbs or trunk, but some of them are only diagnosed after a period of postnatal growth. In case of poor postnatal linear stature, some studies suggest that although having a clear diagnosis of clear osteochondrodysplasia but only in bone endings, if accompanied with extreme discretion, may have a longitudinal or linear growth with GH treatment and limiting growth hormone when segments begin to characterize disproportionate size should be stopped immediately so that no disproportionate members of characteristic form of the disease occurs characterization, because any gain postnatal remembers the traumas that inevitably will come in the wake of the body development, this attitude is rare and is cited only in critical conditions. The most common condition is autosomal dominant achondroplasia (OMIM # 100800)-this condition is characterized by short ends in the next member regions, relatively large head with prominent forehead and depressed nasal bridge and lumbar lordosis throughout life. The linear stature of adulthood is reduced, with a mean of 132 cm for males and 123 cm for females. Intelligence is normal. We identified mutations in the tyrosine kinase domain of the receptor 3 fibroblast growth factor (FGFR3) gene locus at 4p16.3 (OMIM # 134934).
