RÉSUMÉ
Grip strength [GS] is an important measure of general health to predict mortality, disability and function of the hand. The purpose of this study was to develop equations to predict grip strength based on several anthropometric measurements using a multiple regression analysis. Four hundred and eleven males and 671 females college students, ages 18-30 years, in good health, participated voluntarily in this study. This sample was randomly assigned to the model-development [n=867] and cross-validation [n=215] groups. Four equations were developed by using data from the model development group, then cross-validated on the second group. A hand-held dynamometer was used to measure grip strengths. All anthropometric measurements such as hand anthropometry, forearm circumference [FC], lean body mass, skeletal muscle mass and arm muscle area were taken according to standard techniques. It was found that grip strength has a significant correlation with all anthropometric measurements. Forearm length [FL] was correlated to grip [68% explained variance] in a linear relationship, followed by upper limb length and SM. All four equations were confirmed by cross-validation. Because of simplicity and easy-to-measure the following equations were selected for prediction grip: Dominant hand, A] 0.464xAge[yr]+0.392xHeight[cm]+0.681xBMI-13.035xSex[0 for men and 1 for women]-46.160, B] 0.029xFCxFL-8.634xsex+13.872; Non-dominant hand: C] 0.347xAge+0.386x Height+0.657xBMI-13.313xSex-44.243, D] 0.029xFCxFL-8.752xsex+13.788. The six easy-to-measure cofactors sex, age, height, BMI, forearm length and forearm circumference provide a highly accurate prediction of normative grip strength
RÉSUMÉ
1. 300 cases were examined comprising the various types of dermatomycoses in adults at El-Mehalla El-Kobra. 2. 6 cases of scalp infection, 110 cases of tinea carporis, 79 cases of tinea pedum and manum, 58 cases of intertriginous areas, 24 cases of tinea unguum and 23 cases of cutaneous candidosis were examined culturally in the present study. 3. Out of the 300 cases examined, 240 [80%] yielded positive fungus cultures. These included 6 cases of scalp infection [2.5%], 98 cases of tinea corporis [89.09%], 58 cases of tinea pedum and manum [73.41%], 43 cases of axilla, submamary and groin areas [73.27%], 17 cases of tinea of nails [70.83%] and 18 cases of cutaneous candidosis [78.26%] .4. Concerning the incidence of fungal species isolated from the different dermatomycoses of the 300 cases examined culturally, T. violaceum was the most prominant organism as it is was isolated from 67 cases [79.17%], followed by candida albicansfrom 61 cases [21.37%], T. rubrum from 45 cases [14.58%], M. canis from 36 cases [15.0%], E. floccosum from 8 cases [3.33%], T. menta grophytes from 7 cases [2.9%], T. schoenleinii from 6 cases [2.5%], Geotrium candida from 5 cases [2.08] and mixed T. violocum and M. canis from 2 cases [0.83%]
