Subclinical Left Ventricular Dysfunction in Children and Adolescence With Thalassemia Intermedia.

Background: Cardiac complications are important causes of morbidity in patients with thalassemia intermedia (TI). We aimed to assess left ventricular (LV) function, using new tissue Doppler imaging (TDI) indices, in order to diagnose early ventricular impairment in asymptomatic children and adolescence with the TI.

Materials And Methods: We investigated possible differences in echocardiographic systolic and diastolic parameters between a population of 28 asymptomatic patients (mean age, 13.

The Nomogram of Clitoral Length and Width in Iranian Term and Preterm Neonates.

Clitoromegaly is an important parameter in the evaluation of ambiguous genitalia in neonates, but the normative data for clitoral size in newborns have racial/ethnic differences. The present study aimed to determine clitoral length (CL) and clitoral width (CW) values and establish cutoff measurement to define clitoromegaly in both term and preterm Iranian neonates for the first time. A total number of 580 female newborn infants delivered at 28-42 weeks of gestation were enrolled in the study, and their CL and CW were measured on the first 72 h of birth.

The Nomogram of Penile Length and Circumference in Iranian Term and Preterm Neonates.

Background And Objectives: The normal length of penis in preterm and term neonates is different among different nations, and is affected by various factors. The present study aimed to determine stretched penile length (SPL) values and cutoff level of micropenis in term and preterm Iranian neonates, for the first time.

Materials And Methods: All male neonates born in two general hospitals of Tehran (Akbarabadi, and Rasoul hospitals), center of Iran, with gestational age of 28-42 weeks were included and their SPL and penile circumference (PC) were examined on the first 3 days after birth by the same physician.

The prevalence of hypertension in children with renal scars.

Background: Hypertension (HTN) is a late outcome of congenital or acquired renal scar. We used ambulatory blood pressure to assess the early blood pressure abnormalities in children with history of urinary tract infection with various degrees of renal scars.

Methods: Between 2009 and 2011, 60 (45 females, 15 males) children aged 5-15 years and height equal or more than 120 cm with previous history of febrile urinary tract infection were entered into the study.

Carotid artery function in children with idiopathic nephrotic syndrome.

Background: Nephrotic patients are prone to atherosclerosis in consequence of frequent exposures to hyperlipidemia, hypertension, and immunosuppressive drugs.

Objectives: We studied the carotid parameters as early indicators of atherosclerosis in children with nephrotic syndrome.

Methods: Between 2008 and 2011, 51 children with history of nephrotic syndrome enrolled in the study.

Ambulatory blood pressure monitoring for children with β-thalassemia major: a preliminary report.

Introduction: Heart disease is one of the most common reasons of death in beta-thalassemia major. A few studies have been done in children about blood pressure changes. The aim of this study was to assess hemodynamic changes by ambulatory blood pressure monitoring (ABPM).

Evaluation of combined left ventricular function using the myocardial performance index in children with chronic kidney disease.

Background: Myocardial dysfunction that complicates the initial stages of chronic kidney disease (CKD) has not been yet fully characterized in young patients. We aimed to assess the clinical usefulness of myocardial performance index obtained by pulsed-wave Doppler method (PWD-MPI) in predicting early disturbances of global left ventricular (LV) function in children with CKD stages 2-4. In addition, we evaluated the clinical utility of tissue Doppler imaging (TDI) as a tool for calculating MPI in comparison with the conventional method.
