Aim:This study evaluated and compared two impression techniques in terms of their dimensional accuracies to reproduce implant positions on working casts.Materials and Methods:A master model was designed to simulate a clinical situation. Impressions were made using four techniques: (1) Stock open tray (SOT) technique; (2) stock closed tray (SCT) technique; (3) custom open tray (COT) technique; and (3) custom closed tray (CCT) technique. Reference points on the hexagonal silhouette of the implant on master model and onto the analogs of the obtained master casts were compared after using the four impression techniques. Measurements were made using an optical microscope, capable of recording under 50x magnifications. The means and standard deviations of all the groups and subgroups were calculated and statically analyzed using analysis of variance (ANOVA) and Tukey's test.Results:The open tray impressions showed significantly less variation from the master model and all the techniques studied were comparable.Conclusion:All the techniques studied shown some distortion. COT showed the most accurate results of all the techniques.

Introduction:Chronic tophaceous gout classically occurs after 10 years or more of recurrent polyarticular gout. However, tophi can also occur as first sign of the disorder.Case Report:We report the case of a 60 year female with tophaceous involvement of the pubis bone which is an unusual location for this type of pathology without any prior manifestation of gouty arthritis.Conclusion:Tophi can present in unexpected locations, even as the first sign of gout, often mimicking infection and neoplasia and vigilance is required when unusual symptoms or signs occur in a patient with gout.

Abstract:Fracture of mid-shaft humerus is a common occurrence. They have been treated with variety of conservative and surgical modalities and yields high rate of union with plate osteosynthesis. Nonunion is a known complication of fracture mid-shaft humerus due to various factors. Repeat surgery, debridement of fracture edges with bone grafting is universally acceptable treatment for fracture mid-shaft humerus non-union. We present a rare case report of 25 year old fracture mid-shaft nonunion humerus in a 60 year old female treated successfully with conservative treatment.
