Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...

Background. Postoperative sternal instability can be associated with the density of bone and type of wire closure. Sternal instability is a serious complication, especially in diabetic obese patients. This category of patients is susceptible to activation of inflammation and inflammatory and/or infective involvement of the sternum after sternotomy. This study was designed to evaluate the compar...

Background and Aims: Scaphoid fractures are the most common fractures of the wrist. This study compared the outcomes of two surgical internal fixation techniques, using either Herbert screws (HS group) or multiple pins (MP group), in the treatment of scaphoid fractures. Methods: This cross-sectional study was performed on 41 patients (23 in HS and 18 in MP groups) with unilateral scaphoid fract...

We present a patient (male 26 years) with a short history of recurrent seizures induced by a largely intracerebrally located frontal lobe meningioma. The tumor displayed a heretofore unpublished combination of extensive metaplastic bone formation and prominent non-psammomatous calcifications with focal chicken-wire pattern.

Entrapment of prepuce in a zipper is a common cause of prepuceal injury in children. The reported interventions include dismantling the zipper with bone or wire cutters, to circumcision. A quick, simple and non-traumatic approach to the zipper manipulation is presented in which prepuce is instantly released by lateral compression of the zip fastener, using a pliers.

A closed reduction technique using a posteriorly inserted intrafocal Kirschner wire for unstable Gartland type-III supracondylar humeral fractures in children is described. This surgical technique has been used in 7 patients. None had neurovascular complications, and all achieved bone union and had good or excellent functional and cosmetic results.

Revision total hip arthroplasty in the setting of severe acetabular bone loss is a challenging problem that is becoming more common. Kirschner wires are often used during acetabular revision for temporary fixation of trial components. We describe an intraoperative migration of a Kirschner wire through the acetabulum into the peritoneal cavity, requiring acute laparoscopic removal.

The Vibrant Sound Bridge​ (VSB) implant system consists of a receiver/stimulator, gold wire cable and the Floating Mass Transducer​ (FMT) stimulator. FMT is attached by coupler to middle ear structures, including short incus process (SP). With this type attachment, often in contact bone skull base, potentially putting pressure on affecting its ability vibrate. aim study was clinical-experimenta...
