The association between different anesthetic techniques and outcomes in patients undergoing transfemoral aortic valve replacement.

Background: There is an increasing number of patients undergoing transfemoral aortic valve replacement (TAVR) with sedation. There is limited data assessing the efficacy and safety of the different types of sedative drugs. The objective was to compare two sedation techniques with regard to the need for vasoactive support, respiratory support, rate of conversion to general anesthesia (GA), common perioperative morbidities, intensive care unit (ICU) stay, and in-hospital mortality.

Scores predicting atrial fibrillation after mitral valve surgery: Do we need a more specific score?

Background: Atrial fibrillation after cardiac surgery (POAF) is associated with increased morbidity and mortality. Several scores were used to predict POAF, with variable results. Thus, this study assessed the performance of several scoring systems to predict POAF after mitral valve surgery.

Markers of Local and Systemic Estrogen Metabolism in Endometriosis.

Estrogen metabolites (EMs) can work independently from their parent hormones. We hypothesize that in endometriosis, estrogen is metabolized preferentially along hormonally active pathways. We recruited 62 women with endometriosis (proven laparoscopically and histologically) and 52 control women (normal findings with laparoscopy) among patients undergoing surgery for pelvic pain and/or infertility during the proliferative phase of the menstrual cycle.

Detection of Hepatis C Virus-Related Immunologic Markers and Their Impact on Outcomes of Living-Donor Kidney Transplant Recipients.

Objectives: Liver disease is an important cause of morbidity and mortality among recipients of transplanted organs. In addition to the liver, hepatitis C virus infection has a significant prevalence among recipients of kidney transplant and is related to worse graft and recipient survival as the kidney is an important component of the hepatitis C virus clinical syndrome.

Materials And Methods: This retrospective single center study included 336 patients with end-stage renal disease who received a kidney transplant at the Mansoura Urology and Nephrology Center from January 1992 to December 1995.

The impact of excision of benign nonendometriotic ovarian cysts on ovarian reserve: a systematic review.

Background: Benign nonendometriotic ovarian cysts are very common and often require surgical excision. However, there has been a growing concern over the possible damaging effect of this surgery on ovarian reserve.

Objective: The aim of this metaanalysis was to investigate the impact of excision of benign nonendometriotic ovarian cysts on ovarian reserve as determined by serum anti-Müllerian hormone level.

Persistent oxidative stress in patients with chronic active hepatitis-C infection after antiviral therapy failure.

Background/aims: Oxidative stress and hepatocellular pathological changes are common associations with chronic hepatitis C virus (CHC) disease. The aim of this study was to assess serum antioxidant-oxidant (Redox) balance in patients with CHC infection before and after intake of the traditional antiviral therapy (pegylated interferon α-2b and oral ribavirin).

Patients And Methods: Blood samples from 50 biopsy-proven CHC patients, with no prior anti-viral treatment and persistently elevated serum transaminase levels for 6 months, as well as 15 age- and sex-matched healthy subjects were used for determination of the antioxidants: reduced glutathione (GSH), superoxide dismutase (SOD), α tocopherol and ascorbic acid as well as lipid peroxidation (LPO) index (malondialdehyde [MDA]).

"Gestational gigantomastia": a review article and case presentation of a new surgical management option.

Background: Gestational gigantomastia is a nightmare to pregnant women. The currently available surgical intervention is either reduction mammoplasty or simple mastectomy. Reduction mammoplasty carries high risk of recurrence.

Bariatric surgery: Rhabdomyolysis after open Roux-en-Y gastric bypass: a prospective study.

Background: Rhabdomyolysis (RML) is a recently recognized complication of bariatric surgery (BS). The aim of this prospective study was to determine frequency, risk factors, and clinical relevance of RML in morbidly obese patients treated with open Roux-en-Y gastric bypass (RYGBP).

Methods: A total of 23 consecutive patients with morbid obesity undergoing primary open RYGBP were included prospectively in the present study.

Circadian pattern of acute variceal bleeding among cirrhotic Egyptian patients.

Background: Liver cirrhosis is the most common cause of portal hypertension which may end in serious bleeding from gastro-esophageal varices. Recent studies have demonstrated a daily pattern of acute upper gastrointestinal bleeding in patients with liver cirrhosis evidenced by one or two peaks throughout the day.

Aim: The assessment of the circadian rhythm of acute variceal bleeding with the possible participation of circadian changes of the fibrinolytic parameters.

Endothelial dysfunction in geriatric diabetic patients: the role of microalbuminuria in elderly type 2 diabetic patients? A randomized controlled study.

Backgrounds/aims: Microalbuminuria is considered a marker of extensive endothelial dysfunction and is associated with excess of other cardiovascular risk factors. Our aim is to assess the importance of the presence of microalbuminuria in elderly diabetic patients.

Methods: A total of 40 normotensive elderly type 2 diabetic patients of both genders with mean age >65 years were randomly included and were further subdivided according to the presence of persistent microalbuminuria into microalbuminuric and normoalbuminuric groups.

The prevalence of ADHD among primary school children in an Arabian society.

Objective: The aim of this study is to identify Attention Deficit Hyperactivity Disorders among primary school children in the State of Qatar.

Method: A cross-sectional descriptive study is conducted from March 2004 to February 2005. A total of 2,000 primary school students, ages 6 to 12, are selected, and 1,541 students (77.
