RESUMO
To construct some population standards of some of the palmar dermatoglyphic features in the adult Libyans living in Tripoli. A total number of 100 adult Libyan males and 100 adult Libyan females living in Tripoli were used in this study. They were students at Faculty of Medicine, Al-Fateh University during the academic year 2009/2010. Their ages ranged from 18-20 years. For all subject palmar dermatoglyphic studies; Atd angle and a-b ridge count were done. The palmar jiexion creases; normal, Simian, Partial Simian and Sydney pattern were investigated. Mean atd angle of right hand of adult male [33.74] was less than that of the left hand [33.89]. Mean atd angle of the right hand of the adult female [34.37] was less than that of the left hand [34.61]. On the other hand, the mean atd angles of both right and left hands of the male were less than that of the female. A-b ridge count of right hand of male adult [38.31] was less than that of left hand [38.7]. The same result was seen in the female; a-b ridge count of right hand of female adult [35.77] was less than that of the left hand [36.87]. However, the a-b ridge count of both right and left hands of the male are more than that of the female. The percentage of the normal palmar flexion creases was found to be more in both hands of the adult male [81% for both,] than that of both hands of the female [68% for the right hand and 72%/or the left hand]. Conversely, the percentage of the abnormal types of palmar flexion creases was found to be less in both hands of the male [19%] than that present in both hands of the female [32% for the right hand and 28% for the left]. The data of this study discover the presence of sexual differences and bilateral asymmetry of almost all the palmar dermatoglyphic .features studied. The variations may be attributed to the genetic factor influencing their development
RESUMO
The hand measurements were carried out on both hands and all fingers of each volunteer to perform a standard for the Libyan population. Hand print impressions of 200 adult Libyan voluteers [100 males and 100 females] were taken. They are right handed. They live in the city of Tripoli. They are students a Faculty of Medicine, Al-Fateh University. Their ages were from 18-20 years old. They have good health and free of any chronic debilitating disease. The parameters studied were maximum length and breadth of both hands and for each finger of both hands. Hand Index [maximum hand width / hand length X 100] and finger Index [maximum finger width /finger length X 100] for each finger were estimated. The data were analyzed using different histograms. The data show the presence of bisexual highly significant differences and bilateral non-significant differences of almost all hand and finger parameters. Also, these data are different from that found before in other populations. Variations in hand measurements may be attributed to several factors like genetic, racial, geographical, climatic and nutritional. This work is the first study done on Libyans and was presented, discussed and accepted at the First International Congress of Medical Science, Towards Advanced Medical Horizons.
