PURPOSE To determine the immunogenic characterization of amniotic epithelium (AE), by examining the fate of allogeneic AE grafts heterotopically transplanted in the eye. METHODS Intact AE from enhanced green fluorescence protein (EGFP) transgenic mice (C57BL/6 background) and wild-type C57BL/6 mice were transplanted onto cornea or conjunctiva, or inserted into the anterior chamber (AC) of nor...

CONTEXT Fractures of proximal fifth metatarsal are one of the most common fractures of the foot. EVIDENCE ACQUISITION A search of PubMed for studies on proximal fifth metatarsal fracture and Jones fracture focusing on the classification and management was performed. The reference list of the retrieved articles was searched for additional related studies. RESULTS The vascular supply and soft...

Scaphoid nonunion is a common but difficult problem for hand surgeons. The diagnosis of scaphoid nonunion is often delayed, and therefore, treatment must be tailored to the type of fracture, the duration of nonunion, and the presence or absence of resulting arthritis. This article reviews the diagnosis and work-up of scaphoid nonunion, classification schemes for scaphoid nonunion, and various t...

A simple technique for screw fixation of the carpal scaphoid in cases of delayed union and non-union is described. The results obtained in 32 patients treated by this method are reported. The average follow-up was three years ranging from 10 months to 12 years. Union was obtained in 28 patients. The causes of failure to unite are discussed and the advantages of the reported method over other te...

INTRODUCTION Sinus grafting is a technique oriented to facilitate implant placement in posterior atrophic maxillae. Several modifications of the original technique and a wide variety of materials have been proposed; most of them associated with implant survival rates. However, the quality of the bone obtained after the application of certain grafting materials has not been fully elucidated yet....

We report the use of Grosse-Kempf reamed intramedullary nailing in the treatment of 41 Gustilo type II and III open tibial fractures. The union times and infection rates were similar to those previously reported for similar fractures treated by external skeletal fixation, but the incidence of malunion was less and fewer required bone grafting. The role of exchange nailing is discussed and a tre...

Management in patients with coexisting coronary artery disease and lung carcinoma is usually a two-stage operation, with the cardiac surgery procedure followed by pulmonary resection at a later time. Delayed tumor resection on the other hand may be detrimental. Off-pump coronary artery bypass grafting could facilitate concomitant lung resection at one stage via median sternotomy. T-bar retracto...

the cornelian cherry is one of those less common but, nevertheless, interesting fruit species found in serbia which can be used both for food and medicine. due to a great importance of cornelian cherry fruits as safe food and a wide interest in growing this fruit species, this research was focused on examining the production technique of quality planting material of particularly large-fruit sel...

One-stage femoral lengthening is thought to have an unacceptably high complication rate and is not widely practised. We reviewed 17 patients after one-stage lengthening for femoral shortening with associated angular or rotational deformities. Minimal dissection of the bone ends was undertaken. The mean length gain was 4 cm (2 to 7), and the average time to union was 6 months (3 to 10). There we...

The case notes of 34 patients undergoing rehabilitative facial nerve surgery between 1978 and 1994 were retrospectively examined. Thirteen patients underwent facio-hypoglossal transposition with six achieving a facial nerve grade of IV (House-Brackmann scale) at 24 months post-surgery. Twelve patients underwent cable grafting of the facial nerve defect. Of these, 10 achieved a grade III result ...
