Introduction: Concerns regarding the adverse consequences of radiation have increased due to the expanded application of computed tomography (CT) in medical practice. Certain studies have indicated that the radiation dosage depends on the anatomical region, the imaging technique employed and patient-specific variables. The aim of this study is to present fitting models for the estimation of age-specific dose estimates (ASDE), in the same direction of size-specific dose estimates, and effective doses based on patient age, gender and the type of CT examination used in paediatric head, chest and abdomen-pelvis imaging.

Methods: A total of 100 maxillary central incisors were selected.
Objective: To determine the etiology and pathogenesis of enuresis among primary school children by using a special ultrasound (US) protocol for the assessment of bladder dysfunction and to compare excretion of urinary sodium and calcium in enuretic children.
Methods: We conducted this cross sectional study on 66 enuretic children aged 6-12 years from September 2005 to January 2006 in Isfahan University of Medical Sciences, Iran. Ultrasound (US) was designed for the evaluation of bladder parameters using bladder volume and wall thickness index (BVWI%), and expected percentage bladder volume index for kidney volume.
Objective: To estimate the prevalence of enuresis in primary school children in Iran and to determine the factors associated with this disorder.
Methods: A cross-sectional time-ordered study was performed at the Faculty of Medicine, Isfahan Medical University, Isfahan, Iran from September 2005 to January 2006. A total of 4500 self-administered questionnaires were distributed to parents of children aged 6-12 years attending 30 primary schools.
