Osteogenesis imperfecta is a syndrome of interest to dentists because dentinogenesis imperfecta is frequently associated with not only bone disease but also tooth diseas~. Specifically, these patients usually have many dental problems such as 1) high incidence of tooth fracture, enamel chipping and cracking, 2) high caries activity, 3) inability or difficulty of endodontic treatment, 4) mastica...
Recurrent lethal perinatal osteogenesis imperfecta may result from asymptomatic parental mosaicism. A previously unreported mutation in COL1A2 leads to recurrent cases of fetal osteogenesis imperfecta Sillence type IIA, which emphasizes the importance of clinical and genetic evaluation of mosaicism in asymptomatic parents as verified mosaicism highly increases recurrence risk.
purpose: congenital third nerve palsy was generally thought to exist in isolation without associated abnormalities. in this report, we present a case of congenital third nerve palsy in osteogenesis imperfecta. methods: a 6-month-old girl with osteogenesis imperfceta presented with ptosis and large incomitant exotropia in left eye (le) at birth. ocular examination revealed total third nerve pals...
Achondroplasia, Duchenne muscular dystrophy, and osteogenesis imperfecta are among the most frequent rare genetic disorders affecting the musculoskeletal system in children. Rare genetic disorders are severely disabling and can have substantial impacts on families, children, and on healthcare systems. This literature review aims to classify, summarize and compare these non-medical impacts of ac...
Using two restriction site polymorphisms within the structural gene coding for human type II collagen we have examined the segregation of this gene in three pedigrees with dominantly inherited osteogenesis imperfecta (Sillence type IA). We have demonstrated that the gene does not segregate with clinical expression of the disease and cannot, therefore, contain the mutation responsible for osteog...
Osteogenesis imperfecta is a heterogeneous group of genetic disorders that affect the integrity of the connective tissue. Manifestations of the disease include bone fragility, osteoporosis, dentigenesis imperfecta, blue sclera, easy bruising, joint deformity and scoliosis. On the other hand, colonic diverticular disease is the most common acquired disease of the large bowel in the western popul...
The response to the bisphosphonate, pamidronate, is reported in a child with osteogenesis imperfecta who had recurrent symptomatic hypercalcaemia after immobilisation following fractures. Oral clodronate was effective in the prevention of immobilisation hypercalcaemia in the same child. The bisphosphonates may have other roles in osteogenesis imperfecta by decreasing bone turnover.
conclusions although most authors believe that general anesthesia following fiberoptic intubation is the preferred method for oi patients, it is likely that spinal anesthesia is acceptable in such patients. although it is technically difficult, the procedure can be performed by expert anesthesiologists. introduction the choice of anesthetic technique in patients with osteogenesis imperfecta (oi...
Osteogenesis imperfecta is a heterogeneous genetic disorder characterized by bone fragility and deformity, recurrent fractures, blue sclera, short stature, and dentinogenesis imperfecta. Most cases are caused by mutations in COL1A1 and COL1A2 genes. We present a novel splicing mutation in the COL1A1 gene (c.1875+1G>C) in a 16-year-old Brazilian boy diagnosed as a type III osteogenesis imperfect...
The purpose of our study was to screen preliminary differential expression bone-related microRNAs (miRNAs) in serum of patients with osteogenesis imperfacta and to clarify whether serum microRNA is a promising biomarker for osteogenesis imperfecta. geNorm and several other programes were performed to select suitable reference genes for quantitative detection of serum miRNAs from 6 candidate con...
