Relationship between thigh skinfold measurement, hand grip strength, and trunk muscle endurance: Differences between the sexes

This study was conducted to examine the relationship between thigh skinfold measurement, hand grip strength, and trunk muscle endurance and compare this relationship in men and women. The current study included 200 healthy subjects (111 women and 89 men), with a mean age of 31.58±13.78 y. Trunk muscle endurance was evaluated with the use of curl-up, horizontal side bridge, and static back endurance tests. Significant differences were found between women and men in performance of the curl-up and horizontal side bridge tests (P< .05); however, no significant difference was found between the sexes in the static back endurance test scores (P≥.05). The investigators discerned a significant negative correlation between thigh skinfold measurements and all trunk muscle endurance tests in female patients (curl-up,r=−.501; horizontal side bridge,r=−.454; static back,r=−.479;P< .05). A rather weak correlation was found in male patients (curl-up,r=−.348; horizontal side bridge,r=−.182; static back,r=−.330;P< .05). On the other hand, no significant correlation was found between hand grip strength and trunk muscle endurance test scores in female patients (P≥.05), although a significant positive correlation was found in male patients in curl-up and side bridge test results (curl-up,r=.319; horizontal side bridge,r=.307; static back,r=.123;P< .05). The results of this study suggest that women have lower endurance test scores compared with men. The investigators detected the presence of a significant negative correlation between thigh skinfold measurement and trunk muscle endurance tests in both men and women and concluded that there is a positive significant relationship between hand grip strength, curl-up, and horizontal side bridge tests. Additional studies are needed to evaluate the relationship between muscle endurance and physical characteristics as they relate to the sex of the individual.     

The relationship between the severity of erectile dysfunction and aortic stiffness

Aortic stiffness increases in patients with erectile dysfunction (ED) but it is not known whether aortic stiffness affects the degree of ED. In the present study, we aimed to determine whether there is any relationship between aortic stiffness and the severity of ED. Patients with ED were divided into 3 groups according to the International Index of Erectile Function (IIEF) scores. Mild ED was named as group 1, moderate ED as group 2 and severe ED as group 3. The values of fasting blood glucose (FBG), serum lipid values, total testosterone (T. tes), and free testosterone (F tes) were recorded. Aortic stiffness was determined by pulse wave velocity (PWV) and augmentation index (AIX) measurements. The mean or median values of the laboratory parameters among the groups were similar (p > .05). No statistical difference was found between the groups in terms of AIX value (p = .386). Mean PWV values were calculated as 7.26, 8.30 and 8.78 in group 1, group 2 and group 3 respectively. PWV values were significantly different between groups (p < .0001). PWV values were found to be increased with increasing severity of erectile dysfunction.     

Paradox in the cubital tunnel syndrome—frequent involvement of left elbow: first report

Objective

Cubital tunnel syndrome (CuTS) is the second most common compression neuropathy in the arm, but the existence of a compressive cause has not been determined conclusively and the majority of the cases are idiopathic. In this paper, involvement sides of limbs of patients with cubital tunnel syndrome were studied.

Material and methods

Between October 2008 and December 2011, the clinical assessment of consecutive operated patients with cubital tunnel syndrome in Rize Education and Research Hospital were analysed. The diagnosis and severity of syndrome was based on electro-diagnostic study.

Results

This study included 57 consecutive patients with cubital tunnel syndrome (39 men, 18 women; mean age, 44,7 years; range, 23–79 years; mean age, 44,7 years; range, 23–79 years); 31 patients underwent surgical treatment. Involvement was on the right side in 18 and on the left in 39 patients. Severity scores and MCV were statistically significant between sides.

Conclusion

Profound involvement with cubital tunnel was found in left elbow. According to the finding of non-dominant elbow involvement in our study, the exact etiology and ideal management of cubital tunnel syndrome continues to be heavily debated.
