Abdominal obesity is associated with risk of cardiovascular disease and type 2 diabetes mellitus. Waist circumference as a measure of obesity may be clinically useful as a predictor of metabolic syndrome in children. To develop age- and sex-specific reference values for waist circumference we evaluated the data obtained from Turkish children and adolescents. Waist circumference measurements from 4,770 healthy schoolchildren were obtained. Smoothed percentile curves were produced by the LMS method. The median curves of Turkish children were compared with four other countries: Australia, the UK, USA (Bogalusa) and Japan. Smoothed percentile curves and values for the 3rd, 5th, 10th, 25th, 50th, 75th, 85th, 90th, 95th and 97th percentiles were calculated for boys and girls. We found that waist circumference increased with age both in boys and girls. The 50th percentile waist circumference curve of Turkish children was over the British and Japanese but lower than the Bogalusa children and adolescents. This study presents data and smoothed percentile curves for waist circumference of healthy Turkish children aged 7-17 years. The differences in waist circumference of different countries can be explained by lifestyles and cultural characteristics. These data can be added to the existing international reference values for waist circumference of children and adolescents.

Frailty has emerged as an important risk factor for disability. Age-related declines in physical and physiological function lead to increased risk of loss of independence and poor quality of life. Recent evidence has shown the effectiveness of physical exercise programmes in preventing or reversing frailty. The aim of this study was to evaluate changes in the functioning of frail elderly individuals after undergoing resistance training for 3 days a week for 8 weeks. The effectiveness of exercise training was investigated in 48 frail elderly individuals who were randomly assigned to the following intervention groups: high-intensity (HI; n=16; age: 69-96 years) or low-intensity (LI; n=16; age: 77-93 years) strength training groups or a control group (n=16; age: 76-93 years) with no specific exercise programme. Participants were assessed for muscle strength, physical function, activities of daily living, depression and quality of life. The HI group had significantly better results (P<0.05) on the Short Physical Performance Test than the LI group; however, the LI group did show a significant improvement in those scores, whereas the scores of the control group worsened. Results for the other evaluations were similarly favourable in both exercise groups (P>0.05). The study showed that LI exercise was as effective as HI exercise for most parameters tested. Exercise training is useful for the prevention or treatment of frailty, as it improves functioning by contributing positively to muscle strength, gait, balance and quality of life.

Objective: The purpose of this study was to determine the cut−off values for waist circumference (WC) and mid−upper arm circumference (MUAC) and to assess their use in screening for obesity in children.Methods: Anthropometric measurements of a total of 2621 boys and 2737 girls aged 6−17 years were analyzed. WC and MUAC values were compared with ROC analysis using body mass index (BMI) cut−off values of the International Obesity Task Force (IOTF) and using WC≥ 90th percentile.for MUAC.Results: In both genders, except for boys and girls in the 6−year age group and post−pubertal boys, the differences between area under curve (AUC) values for WC and MUAC were not significant, indicating that both indices performed equally well in predicting obesity. Sensitivity was suboptimal through age groups 6−9 years in the boys and sensitivity was suboptimal at 6, 7,14 and 17 years both in boys and girls.Conclusions: We conclude that MUAC can be a useful parameter in screening obesity and body fat distribution in children and, can be applied in epidemiological studies and in clinical practice.Conflict of interest:None declared.

This study provides NC percentiles, means and medians values and analyses their significance in obesity evaluation in clinical practice.

The aim of this study was to evaluate the clinical presentation of, predisposing factors in, and early and long-term outcome of patients treated surgically for intraperitoneal ruptured liver hydatid cysts. Medical records of 27 patients with traumatic rupture of hydatid cysts were evaluated retrospectively, as were records of 347 patients with nonperforated hydatid cysts. The ratio of perforation cases to nonperforation cases was 7.8%. Traffic accidents were the most common cause of perforation (n = 16). All patients had abdominal findings, and two patients (7%) had anaphylactic findings. The sensitivities of computed tomography and ultrasonography were 100% and 93%, respectively. Conservative surgical procedures were used for 80.5% of cysts and radical procedures for 19.5%. Associated organ injuries were determined in 10 patients. No significant difference was found between patients with peritoneal perforation and those without perforation in terms of sex (p = 0.403), previous hydatid disease surgery (p = 0.565), localization (p = 0.241), number of cysts (p = 0.537), presence of cystic content infection (p = 0.65), or presence of bile duct communication (p = 0.37). However, there were significant differences in age (p = 0.004), cyst diameter ( > 10 cm) (p = 0.03), and presence of superficially localized cysts (p = 0.011). Three patients developed recurrence. In the group of patients with perforation, the complication and recurrence rates were not statistically different in a comparison of surgical techniques (p = 0.37). No postoperative deaths occurred. The main predisposing factors for cyst perforation are young age and superficial localization. Peritoneal rupture increases the rates of postoperative morbidity and recurrence; in contrast, there was no significant relation between the operative procedure and the morbidity and recurrence rates.

In respect to falls, spasticity is also an indicator for chronic stroke patients, as is motor impairment, functional situation, impairment of balance and walking. Sensory impairment, using a walking aid and the type were found to be ineffective.

Since BMI may not always reflect body fat content, direct assessment of adiposity by a practical method would be significantly useful for clinical decisions. Therefore, this study provides normative data for body fat percentage in healthy Turkish children and adolescents. To this goal we used a practical and clinically applicable method. These references can be useful for evaluation of overweight and obesity.

rats were given distilled water (orally) through 15 days and physiological saline (intraperitoneally) instead of MTX was administered on the 10th day in a similar manner. On the 16th day, liver tissue samples were obtained under deep anaesthesia. The level of malondialdehyde (MDA), an end product of lipid peroxidation, and the activities of süperoxide dismutase (SOD) and catalase (CAT), two important endogenous antioxidants, were evaluated in the tissue homogenates. MTX administration increased the MDA level and decreased the SOD and CAT activities in the liver homogenates (p < 0.001), while these alterations were significantly reversed by GSE treatment (p < 0.001). MTX led to significantly reduced whole blood count parameters (p < 0.05). When GSE was supplemented, no significant changes in blood count parameters were noted. It appears that GSE protects the rat liver and inhibits methotrexate-induced oxidative stress. These data indicate that GSE may be of therapeutic benefit when used with MTX.
