A total of 146 consecutive patients with rheumatic MS were screened. They were accepted to be in AF group and sinus rhythm group according to their rhythm in the baseline ECG. After screening, 38 patients were excluded due to hyperthyroidism (n = 13), chronic obstructive pulmonary disease (n = 22), malignancy (n = 2) and rheumatoid arthritis (n = 1). Therefore, remaining 108 patients, 74 of whom in sinus rhythm (MS-SR) and 34 of whom in AF (MS-AF) constituted study population. Fourty age- and gender-matched patients constituted control group. Factors associated with development of AF in multivariable analysis included High sensitivity C reactive protein (P = 0.005; odds ratio, 3.44; 95% confidence interval, 1.44-8.22), N-terminal of brain natriuretic peptide precursor (P < 0.0001; odds ratio, 1.03; 95% confidence interval, 1.02-1.06) and left atrial diameter (P < 0.0001; odds ratio, 1.68; 95% confidence interval, 1.32-2.14). Present study suggests that High sensitivity C reactive protein, N-terminal of brain natriuretic peptide precursor and left atrial diameter are associated with development AF in patients with MS.

A total of 4259 children (2057 females and 2022 males aged 10-14 years old) were screened. Thirty-nine children had a positive forward bending test. The prevalence of scoliosis was 25 per 1000 in the screened population. The ratio of girls to boys with scoliosis was 2.5:1. A minor curve was detected in 72.7% of children with scoliosis (Cobb angle of 10-20 degrees), and a major curve was found in 27.3% (Cobb angle >20 degrees). The cost of screening was found to be 47 cents per child, but the cost per case of scoliosis was determined to be $236.81. School screening for scoliosis seems to be cost-effective in Turkey.

In the analysis, rigid, beam and 3D solid crankshaft models are used. Main bearing load results of rigid, beam and 3D solid models are compared and beam model is
