AIM To determine endothelin-1 (ET-1) concentration before and after surgical coarctectomy and evaluate its association with left ventricular geometric change. METHODS A prospective, cohort study of 24 patients aged 2 d to 10 years with coarctation of the aorta undergoing surgical repair. A sub-cohort of patients with age < 1 mo was classified as "neonates". Echocardiograms were performed just...

one of most challenging problems in neuroradiology is differentiation lesions in brain and another challenging problems is post op. or post radiation/post chemotherapy changes vs recurrence /remnant. on this lecture i am going to show you many cases that on the basis of new technique such as swi, pwi, mrs, cine mri, dti and tractography we can achieve the final diagnosis.

SIOC is an alternative to laparoscopic cholecystectomy. From Jun 2012 through 2013 till Jan 2014, all the SIOC and operations performed on Gall bladder as the responsibility for surgical training (intended SIOC) were taken in to consideration in this study. 92 women and 48 men, total 140, with median age of 45 years (range 18 to 74 years) underwent cholecystectomy for symptomatic gall bladder d...

OBJECTIVE To evaluate the prevalence, impact and outcome of repair of atrioventricular valve regurgitation (AVVR) in Fontan patients. METHODS We retrospectively reviewed 340 Fontan patients from 1986 to 2001. Twelve patients with valve closure or replacements were excluded. AVVR was graded by transthoracic echocardiography. Patients were divided into group O (no AVVR), group A (1+ to 2+) and ...

BACKGROUND/AIM The aim of this study was to gauge whether removal of a specimen with traction during robot-assisted laparoscopic radical prostatectomy causes a positive surgical margin or not. MATERIALS AND METHODS One hundred and sixty-nine patients with localized prostate cancer who underwent robot-assisted laparoscopic radical prostatectomy from 2009 to 2011 were included in the study. Aft...

Background: Techniques that allow early muscle activation, such as closed kinetic chain (CKC) and open kineticchain (OKC) exercises, may play a beneficial role in the early rehabilitation of the reconstructed knee. However,current rehabilitation regimens have not been shown to reverse post-operative quadriceps activation failureand weakness. To investigate whether patients who use a continuous ...

Background: Cirrhotic patients have higher rates of hypercoagulable disorders. We hypothesized that orthotopic liver transplant (OLT) recipients with pre-operative portal vein thrombosis (PVT) have more postoperative thrombotic events than those without PVT. Aims: To compare rates of post-op thrombotic events and outcomes between those with and without pre-op PVT. Methods: All OLT recipients be...

BACKGROUND Despite the favorable efficacy, safety, and cost-effectiveness profile of bisphosphonate (BIS) treatment for osteoporosis (OP), patient compliance remains suboptimal. A longer follow-up period could help to better characterize patient behavior as well as the predictors of noncompliance because of the extended durations of osteoporosis and time to a fracture. OBJECTIVE To determine ...

  Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls.   Methods: The patients with RA on follow-up examination were stratified according to age of onset. ...
