Prenatal diagnosis of accessory mitral valve tissue in a fetus with persistent dysrhythmia.

Background: Accessory mitral valve tissue (AMVT) is a rare congenital cardiac anomaly that mainly diagnosed in the first decade of life. However, asymptomatic cases may not be diagnosed even up to adulthood. We report a fetus with AMVT to show the diagnostic ability of the fetal echocardiography for detection of this pathology in the prenatal period.

Cardiac Calcified Amorphous Tumor in the Neonatal Period.

Calcified amorphous tumor (CAT) of the heart is a rare nonneoplastic cardiac mass that may exhibit symptoms resembling malignancy. In this report, we presented a 4-month-old male baby with repeated attacks of cyanosis and a cardiac murmur. Echocardiography revealed a tumoral noncircumscribed mass in the right atrium adhering to the interatrial septum which extends to the inferior vena cava.

A prospective cohort study on association of first-trimester serum biomarkers and risk of isolated foetal congenital heart defects.

Background: This study aims to assess the association between first-trimester biomarkers in foetuses with a non-chromosomal congenital heart defect (CHD) and compares it to the matched healthy foetuses.

Method: Nuchal Translucency (NT), Pregnancy-Associated Plasma Protein-A (PAPP-A) and free beta-human Chorionic Gonadotropin (β-hCG) were evaluated in 56 isolated foetal heart defects and 224 controls. The CHDs were further divided into Critical CHD (C-CHD) and Non-critical CHD (N-CHD) groups.

Comparing the frequency of polycystic ovary syndrome in women with and without epilepsy.

Introduction: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders; the impact of epilepsy and antiepileptic drugs influences the function of hypothalamic-pituitary-gonadal axis and dysfunction of the endocrine system and reproductive hormones in women with epilepsy. This study was carried out with an aim of determining and comparing the frequency and intensity of the complications of the hirsutism in women with and without epilepsy in Tehran in 2016-2017.

Materials And Methods: This is a cross-sectional-comparative study which was carried out on 338 women of 18-35-year-old women with and without epilepsy who were selected by continuous sampling method.

Noninvasive Evaluation of Myocardial Systolic Dysfunction in the Early Stage of Kawasaki Disease: A Speckle-Tracking Echocardiography Study.

Background: Evaluation of myocardial function by speckle-tracking echocardiography is a new method for the early diagnosis of systolic dysfunction.

Objectives: We aimed to determine myocardial speckle-tracking echocardiography indices in Kawasaki Disease (KD) patients and compare them with the same indices in control subjects.

Patients And Methods: Thirty-two patients (65.

The role of zinc sulfate in acute bronchiolitis in patients aged 2 to 23 months.

Objective: Evaluating the effect of zinc sulfate in improving the clinical manifestations of acute bronchiolitis in children younger than 2 years.

Methods: This was a double blind pilot trial on 50 patients aged 2 to 23 months at Ghaem and Dr. Sheikh Hospitals in Mashhad from January 2008 to March 2009.

In vitro evaluation of force-expansion characteristics in a newly designed orthodontic expansion screw compared to conventional screws.

Objective: Expansion screws like Hyrax, Haas and other types, produce heavy interrupted forces which are unfavorable for dental movement and could be harmful to the tooth and periodontium. The other disadvantage of these screws is the need for patient cooperation for their regular activation. The purpose of this study was to design a screw and compare its force- expansion curve with other types.

Effect of MRI on the mechanical properties of stainless steel orthodontic wires.

Aim: To assess whether the forces created by the magnetic resonance imaging (MRI) field cause a deflection of orthodontic stainless steel archwires or a change of their mechanical properties.

Methods: Sixty stainless steel 0.016-inch archwires were divided into three groups of 20 wires each.
