Evaluating Necessity of Azygos Vein Ligation in Primary Repair of Esophageal Atresia.

Surgery has dramatically improved survival of infants with esophageal atresia. However, early and late complications of these surgeries affect the future life of this population. A probable step toward minimizing such complications is through modifying the technique of surgery.

Age-Related Macular Degeneration: A Scientometric Analysis.

Age-related macular degeneration (ARMD) is a major cause of central blindness among working aged adults across the world. Systematic research planning on any subject, including ARMD is in need of solid data regarding previous efforts in this field and to identify the gaps in the research. This study aimed to elucidate the most important trends, directions, and gap in this subject.

Association of cagA Positive Helicobacter pylori Infection and Laryngeal Squamous Cell Carcinoma: A PCR Approach.

Helicobacter pylori is a gram-negative bacillus causing benign and malignant gastric diseases such as gastroesophageal reflux (GER). In larynx, H. pylori causes chronic inflammation and mucosal destruction that may lead to malignant changes.

Late umbilical cord clamping, neonatal hematocrit and Apgar scores: a randomized controlled trial.

Objective: Based on current evidence, there is a little agreement on the best timing for after birth umbilical cord clamping. This study was designed to compare the impact of using two different times for cord clamping on hematocrit concentration and Apgar scores of the neonate.

Study Design: Fifty-six healthy full-term vaginally born neonates were allocated to early (10 seconds after delivery) and late (3 minutes after delivery) umbilical cord clamping groups in this randomized clinical trial.

A comparative study of treatment outcomes between begg and edgewise orthodontic systems in class I cases.

Background: The purpose of this study was to compare the occlusal peer assessment rating (PAR) index in Class I patients treated by means of Begg and Edgewise methods.

Materials And Methods: The pre- and post-treatment study models of Class I patients, referred to two private clinics, treated with Begg method (n = 30) and standard Edgewise method (n = 30), were reviewed retrospectively using PAR index including dental displacements, buccal occlusion (anteroposterior, vertical and transverse), overjet, overbite and midline parameters. The changes in PAR indices were analyzed using paired t-test.

Immunohistochemical analysis of B-cell lymphoma -2 in pleomorphic adenoma and mucoepidermoid carcinoma.

Background: Salivary gland tumors form a major area in the field of oral pathology. B-cell lymphoma -2 (Bcl-2) is an anti-apoptotic gene with up-regulation in various neoplasms. The aim of the present case-control study was to comparatively investigate the expression of Bcl-2 protein in pleomorphic adenoma (PA) and mucoepidermoid carcinoma (MEC) and assess its potential diagnostic role in differentiating these tumors.

Erectile dysfunction as a predictor of early stage of coronary artery disease.

Background: Diagnosis of coronary artery disease (CAD) in early stages is vital in decreasing mortality by reducing the risk factors. The aim of this study was to investigate the association between erectile dysfunction (ED) and CAD.

Methods: A total of 200 patients were divided into four groups according to their angiography results: Group 1 (G1, n = 59): patients with one-vessel disease (1-VD); Group 2 (G2, n = 40): patients with two-vessel disease (2-VD); Group 3 (G3, n = 50): patients with three-vessel disease (3-VD); and controls (C, n = 51) without any coronary disease.

Smile line and occlusion: An epidemiological study.

Background: The purpose of the present study was to discuss some new concepts of the desirable characteristics of smile tooth display. Due to the increasing application of cosmetic dental treatments, there is an increasing need for better understanding of the esthetic principles.

Materials And Methods: In the present descriptive study, with 212 participants, included were patients with no history of orthodontic treatment, loss or prosthetic replacement of anterior teeth, extracted teeth, lips with asymmetry or a history of trauma.

Efficacy of Polyunsaturated Fatty Acids (PUFA) in the Treatment of Attention Deficit Hyperactivity Disorder.

Objective: We aimed to investigate the efficacy of polyunsaturated fatty acids (PUFAs) as an adjuvant treatment in patients with ADHD receiving methylphenidate as well as its side effects.

Method: This randomized clinical trial was conducted on 40 ADHD patients aged between 6 and 12 years. Both treatment and placebo groups received methylphenidate.
