Background Dermatoglyphics could assist in the diagnosis of congenital abnormalities. The aim of this study was to identify the dermatoglyphic patterns (finger print pattern type, total ridge count of each finger, a-b ridge count, and articulotrochanteric distance [ATD angles]) in the parents of cystic fibrosis children. Materials and Methods We recruited 75 parents of children with cystic fibr...

BACKGROUND Several studies have reported alterations in finger and a-b ridge counts, and their derived measures of asymmetry, in schizophrenia compared to controls. Because ridges are fully formed by the end of the second trimester, they may provide clues to disturbed early development. The aim of this study was to assess these measures in a sample of patients with psychosis and normal controls...

OBJECTIVE It is believed that fingerprints and palm patterns may represent genetically determined congenital abnormalities in Cystic Fibrosis (CF). The main idea of this paper was to determine differences of fingerprints and palm patterns in CF and normal children. METHODS Forty-six CF children (27 males, 19 females) and 341 (113 males, 228 females) healthy individuals were recruited for this...

Schizophrenic subjects were compared to normal and psychiatric control subjects for degree of fluctuating asymmetry in two dermatoglyphic traits, a-b ridge count and fingertip pattern. The schizophrenic group exhibited significantly greater fluctuating asymmetry than either control group. Furthermore, indicators of disease severity such as early onset and declining course of illness correlated ...

the aim of the this work was to determine the finger patterns, finger ridge count (frc), total finger ridge count (tfrc), and asymmetry of finger ridge count (afrc) of an iranian girl (aged 13 years) affected with congenital cutis laxa (ccl).the fingerprints of the first phalanx of both hands were taken by using the standard method (stamp ink). the fingerprints were classified according to the ...

Background: Recreational drugs have a significant impact on the lives of drug users, their close families and friends, as well as their society. Social, psychological, biological, and genetic factors could make a person more prone to using recreational drugs. Finger and A-B ridges (dermatoglyphics) are formed during the first and second trimesters of fetal development, under the influence of en...

Three dermatoglyphic traits, viz; finger patterns, finger ridge counts, and palmer a-b ridge counts of 57 (M-29; F-28) and 64 (M-29; F-35). Schizophrenics with and without positive family history respectively, and 65 controls (M-30, F-35), were analysed to determine their level of fluctuating asymmetry.Uniformly higher fluctuating asymmetry was observed in the loop ridge counts of second digits...

Gender classification from fingerprints is an important step in forensic anthropology in order to identify the gender of a criminal and minimize the list of suspects search. A dataset of 10-fingerprint images for 2200 persons of different ages and gender (1100 males and 1100 females) was analyzed. Features extracted were; ridge count, ridge thickness to valley thickness ratio (RTVTR), white lin...
