The sub trochanteric zone of the femur is the area extending up till 5 cm distally from the inferior border of the lesser trochanter or the junction of the proximal third and middle third of the femoral shaft. Fracture patterns presenting major displacement in this area are considered sub trochanteric fractures despite their proximal or distal extension. 1 High biomechanical stress concentratio...
We hypothesized that the endogenous coronary vasodilator adenosine may reduce infarct size by progressively increasing reflow in a preparation of coronary occlusion-reperfusion. After 90 min of proximal left anterior descending artery occlusion, 20 dogs were randomized to blood reperfusion with (n = 10) or without (n = 10) adenosine into the proximal left anterior descending vessel at 3.75 mg/m...
INTRODUCTION The purpose of the current study was to investigate the reaction of the femur to the implantation of the MiniHipTM in terms of: (1) bone density change during one year; (2) correlations between stem length, CCD (caput-collum-diaphyseal), femoral offset, T-value, and bone density; (3) other co-variables that influence the change of bone density. PATIENTS AND METHODS MiniHipTM impl...
Background: In this study we evaluated the treatment of giant cell tumor (GCT) of long bones using cryosurgery combined with curettage and polymethylmetacrylate (PMMA) cementing.Material and methods: From January 1999 to December 2004, twenty patients (mean age at the time of surgery 29.2 years) 13 females and 7 males were included in the study. Cortical disruption were presented in 7 patients ...
ObjectiveWith growing experience of acute type A aortic dissection repair, Zone 2 arch repair has been advocated. The aim this study is to compare the outcome between “proximal-first” and “arch-first” repair.MethodsFrom January 2015 March 2023, 45 patients underwent out 208 repairs: arch-first, N = 19, proximal-first technique, 26, since 2021. Indications were or descending tear, complex in nec...
BACKGROUND The fractional flow reserve (FFR) value of 0.75 has been validated against ischemic testing, whereas the FFR value of 0.80 has been widely accepted to guide clinical decision making. However, revascularization when FFR is 0.76 to 0.80, within the so-called gray zone, is still debatable. METHODS AND RESULTS From February 1997 to June 2013, all patients with single-segment disease an...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Background and Aims: Iatrogenic damage to adjacent tooth during proximal cavity preparation is one of the most common side effects in operative dentistry. The aim of this study was to determine prevalence of iatrogenic damages to adjacent tooth during the preparation of proximal Class II cavities among undergraduate students at dental faculty of Tehran University of Medical Sciences in 2010 ....
