50 PRACTICAL DIABETES VOL. 32 NO. 2 COPYRIGHT © 2015 JOHN WILEY & SONS Introduction Dermatoglyphics are ridged patterns on the palmar and plantar surfaces of humans (fingerprints, palm prints and foot prints), which develop approximately between the 13th and 18th weeks of gestation. They manifest complex genetic backgrounds that are currently not fully explained, but polygenic multifactorial inheritance is the most agreed upon inheritance mechanism.1,2 Among the numerous quantitative and qualitative dermatoglyphic traits, commonly assessed variables include: fingerprint patterns (whorl, loop, or arch), finger ridge counts (total [TFRC] and absolute [AFRC]), palmar angles (‘atd’, ‘adt’, and ‘dat’), palmar a–b ridge counts, and palmar axial triradius positions (t, t’, t’’). (See Figures 1 and 2.) This article refers to recent widespread research which has drawn attention to dermatoglyphic differences between individuals or groups affected by diabetes and those without diabetes; such research highlights the possibility of employing dermatoglyphic differences as diagnostic aids and preventive tools to alert those with a genetic predisposition. The strengths and weaknesses of these studies are underlined, thus serving as a guide for future research in this area.

Early screening of gestational diabetes mellitus using maternal hemoglobin A1C: Revision of current screening guidelines
Background: HbA1C has been a known predictor and diagnostic test for diabetes type 2. However, this test has not yet been widely studied in GDM and more importantly no cutoff point has been defined for HbA1C in GDM. We investigated the efficacy of screening during first and second trimester of pregnancy and defined appropriate cutoff points according to HbA1C and FBS for predicting maternal GDM...
متن کاملDermatoglyphics : A Marker of Periodontal Disease
Dermatoglyphics is the scientific study of fingerprint patterns. Fingerprints are formed in early embryonic life, during the 10th to 16th weeks of intrauterine life and remain permanent during the whole life. Dermatoglyphics can be used as a diagnostic tool of genetically and nongenetically determined diseases. Thus, it can be used not only in the field of medicine but also in dentistry for the...

Background: Dermatoglyphics refers to the study of epidermal ridge patterns of fingers, palms and soles of hand and feet. Fingerprint develops completely at 24th week of embryonic life. Once formed, they are permanent and unalterable throughout the life, not affected by environmental factors. As dermatoglyphic patterns are assumed to be associated with genetic factors, the idea of using it as s...
متن کاملAlopecia Areata and Dermatoglyphics
Objective: To study of relationship between alopecia areata and finger print dermatoglyphic types in 100 patients with alopecia areata and in 100 controls. Methods: A case control analytical study was done on fingerprints of patients with alopecia areata. The control cases were older than 50 years old without any history of alopecia areata. Dermatoglyphical trials of total fingers were al...
