    ABSTRACT: Semispinalis capitis muscle (SECM) is a massive and long cervico-thoracic muscle which functions as a main head and neck extensor muscle. The aim of this study was to detect the effect of head and neck positions on the strength of neck extensor muscles and size of SECM in healthy subjects. Thirty healthy women students voluntarily participated in this study. An ultrasonography apparatus (Hitachi EUB 525) and a system of tension-meter were used to scan the right SECM at the level of third cervical spine and to measure the strength of neck extensor muscles at three head and neck positions. Neck extensor muscles were stronger in neutral than flexion or than extension positions while the size of SECM was larger in extension than neutral or than flexion position. The force generation capacity of the main neck extensor muscle was lower at two head and neck flexion and extension positions than neutral position.

    ABSTRACT: Carotid intima-media thickness (CIMT) could be used as a surrogate marker of atherosclerosis in hemodialysis patients. Since different mechanisms are involved in the atheroma formation and arterial wall thickness, we assessed the relationship between the maximum and the mean CIMT with different cardiovascular risk factors in dialysis patients. The mean and the maximum CIMT were measured using a B-mode ultrasonography in 75 hemodialysis patients, and the correlation between CIMT and cardiovascular risk factors were assessed. The mean and maximum CIMT measurements were 0.5 mm (range, 0.2 mm to 1 mm) and 3.4 mm (1.4 mm to 5.6 mm), respectively. Among all the studied variables, age (P = .04, r = 0.238), HS-CRP (P = .01, r = 0.284), mean arterial blood pressure (P = .003, r = 0.343), and DM (P = .02) had significant correlations with the mean CIMT, while only age (P = .02, r = 0.473) and serum creatinine levels (P = .02, r = -0.493) were significantly associated with the maximum CIMT. A positive nonsignificant correlation was observed between the mean and maximum CIMT values (P = .08, R2 linear = 0.214). These findings suggest that in dialysis patients, effects of cardiovascular risk factors on the mean and maximum CIMT might be different. Further studies are recommended to evaluate the prediction impact of each risk factor in end-stage renal disease patients compared with otherwise healthy individuals.
