PURPOSE To compare the anatomic and functional outcomes of pars plana vitrectomy (PPV) for treating rhegmatogenous retinal detachments (RRDs) between two groups with and without postoperative prone positioning. METHODS This retrospective cohort study included 142 eyes of 142 patients with a primary RRD. All patients underwent PPV with 20% sulfur hexafluoride gas tamponade and were divided int...

BACKGROUND Traumatic injuries caused to anterior teeth are most common. Emergency management of fractured fragments is necessary, for preserving their vitalities and for retaining aesthetics in an economical way. Various methods are available for restoring fractured, uncomplicated teeth, such as reattachment of fractured fragments, composite restoration. But only limited data is available on ev...

The macula of the neural retina from 12 adult rhesus monkeys (Macaca mulatto) was detached from the overlying retinal pigment epithelium (RPE) by subretinal injection of a balanced salt solution. Seven days later, the two layers were reapposed by draining fluid from the vitreous cavity and replacing it with a 3:1 mixture of sulphur hexafluoride gas and air. Animals were sacrificed at 1 hr, 2 da...

Background. Fracture by trauma is one of the most common types of dental injury in the permanent dentition among children and teenagers. Aim. The aim of this study was to report the treatment performed to an atypical dental trauma case in a maxillary central incisor of a young patient by means of reattachment of the tooth fragment. Case Description. A 12-year-old male patient suffered a vertica...

We have recently described patterns of adhesion of different types of leukocytes downstream of a backward facing step. Here the predicted fluid dynamics in channels incorporating backward facing steps are described, and related to the measured velocities of flowing cells, patterns of attachment and characteristics of rolling adhesion for neutrophils perfused over P-selectin. Deeper (upstream de...

The advances in adhesive dentistry have allowed dentists to use the patient’s own fragment to restore the fractured tooth. The present case report describes management of a complicated fracture of maxillary right central incisor treated endodontically, followed by reattachment of the same fragment using fiber post. Reattachment of fractured tooth fragments offers a viable restorative alternativ...
