Color image segmentation based on different color space models using automatic GrabCut.

This paper presents a comparative study using different color spaces to evaluate the performance of color image segmentation using the automatic GrabCut technique. GrabCut is considered as one of the semiautomatic image segmentation techniques, since it requires user interaction for the initialization of the segmentation process. The automation of the GrabCut technique is proposed as a modification of the original semiautomatic one in order to eliminate the user interaction.

Glenoid Bone Loss Measurement in Recurrent Shoulder Dislocation: Assessment of Measurement Agreement Between CT and MRI.

Background: Shoulder instability can cause both soft tissue injury and bone defects, requiring both computed tomography (CT) and magnetic resonance imaging (MRI) for a thorough workup, which results in high patient costs and radiation exposure. Prior studies in cadaveric and nonclinical models have shown promise in assessing preoperative bone loss utilizing MRI.

Purpose: To evaluate the utility of MRI in detecting and evaluating glenoid bone defects in a clinical setting.

Thyroid volumes and iodine status in Egyptian South Sinai schoolchildren.

Introduction: The determination of goitre prevalence in children by ultrasonography is an important tool for considering iodine deficiency disorders. Our objective was to describe measurements of thyroid volumes by ultrasonography in Egyptian South Sinai schoolchildren and compare these with the WHO/International Council for the Control of Iodine Deficiency Disorders normative thyroid volume criteria (WHO/ICCIDD).

Material And Methods: Cross-sectional thyroid ultrasonographic data of 719 schoolchildren (339 boys and 380 girls), aged 6-12 years from five cities in South Sinai (El Tur (T), Abu Redis (R), Ras Sudr (S), Saint Katherine (SK), and Nwebaa (N)).

Effect of an intervention to improve the management of patients with diabetes in primary care practice.

Objective: To assess the effect of an intervention targeted at primary care physicians (PCPs) in order to improve their management of diabetic patients.

Methods: Diabetic patients seen by PCPs in King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from January 2008 to July 2009 were included in this prospective cohort study. The PCPs were divided into intervention and control groups.
