BACKGROUND Upper limb deformity in children with osteogenesis imperfecta may substantially impair function. The aims of this retrospective work were to study the prevalence of radial head malalignment (dislocation or subluxation) in different types of osteogenesis imperfecta and to identify factors linked to it. METHODS We assessed 489 upper limbs from 254 patients (with a mean age of 9.6 yea...

Patients with complete or partial edentulism who have insufficient bone for endosseous dental implant treatment present a challenge for the dental practitioner. Alveolar distraction osteogenesis is a technique for creating bone and soft tissue, without the need for bone grafting and its potential complications. In this article, alveolar distraction osteogenesis is compared with traditional bone...

Heterotopic pregnancy is a potentially fatal condition that rarely occurs in natural conception cycles. We report two cases diagnosed within one month in a 20 year old gravida 3, para 0+2 without any known risk factor and a 38 year old gravida 12, para 6+5 with risk factors. The ectopic pregnancies were diagnosed after rupturing at 10 and 17 weeks respectively and resected via laparotomies. The...

Osteogenesis is a complex process that involves the synergistic contribution of multiple cell types and numerous growth factors (GFs). To develop effective bone tissue engineering strategies employing GFs, it is essential to delineate the complex and interconnected role of GFs in osteogenesis. The studies investigating the temporal involvement of GFs in osteogenesis are limited to in vitro stud...

In the traditional economic order quantity/economic production quantity model, most of the items considered are of perfect type. But this situation rarely takes place in practice. Thus, in this paper, an economic order quantity model with imperfectquality items is developed. 100% screening process is performed, and the items of imperfect quality are sold as a single batch. A proportionate ra...

Osteogenesis imperfecta is a disorder of connective tissue, existing in a severe form (congenita) and a milder form (tarda) both being inherited as an autosomal dominant (McKusick, 1966). Recently Aeschlimann, Grunt, and Crigler (1966) and Bilginturan and Ozsoylu (1966) reported three infants with osteogenesis imperfecta congenita who improved, as regards survival and frequency of spontaneous f...
