Dermatoglyphics in cases of hypospadias: New data

Data on digital and palmar dermatoglyphics in 40 males hospitalized at the Urological Clinic of the University of Cagliari are given. Data on hypospadias patients are compared to those of 106 apparently healthy Sardinian males for digital dermatoglyphics and of 180 for palmar dermatoglyphics In hypospadias patients there is a significant decrease of patterns in the hypothenar area and an increase of radial arches in hypothenar area, while for other characteristics the differences are always not significant.     

Dermatoglyphic patterns and pattern intensities of the genus Cacajao (Cebidae,platyrrhini) with observations on interspecific and subspecific differentiation

Palmar and plantar dermatoglyphic pattern types, area and total pattern intensities (API and TPI), and pattern intensity (PI) profiles are presented for the South American genus Cacajao of the subfamily Pitheciinae. The data are based on prints from 41 bald-head uacaries (C. calvus), 9 white bald-head uacaries (C. c. calvus), and 15 black-head uacaries (C. melanocephalus). In each extremity, loops of differing orientation were the most frequent pattern type; whorls were dominant at palmar interdigital (I) area 3 in C. calvus and at both I3 and I4 in C. melanocephalus. Open fields characterized the palmar thenar and plantar proximal hypothenar, thenar, calcar, and I3 and I4. There was little evidence of significant sexual dimorphism as assessed from PI values. The genus displayed significant asymmetry at palmar I3 (P?0.001) and plantar distal hypothenar (P?0.004). There were significant group differences between C. calvus and C. c. calvus in the palmar thenar API and plantar TPIs. The combined bald-head sample of C. calvus and C. c. calvus differed from C. melanocephalus in API of palmar I4 and plantar distal thenar, I2, and distal hypothenar (marginally), and in plantar TPIs. In PI profiles, C. melanocephalus departed from the pattern shared by C. calvus and C. c. calvus in both palmar and plantar interdigital areas. As a genus, the uacaries have markedly low plantar TPI values relative to palmar values (palm-sole index > 195). Of eight comparison cebid genera, only Chiropotes, another pitheciine genus, approximated these values.

Finger and palmar dermatoglyphics in Seminole Indians of Florida

Hand prints of 146 Florida Seminoles were obtained at the Brighton, Big Cypress and Dania reservations and at the Indian Agency in Dania. Comparisons with other tribes of North American Indians (Comanche, Arapahoe, Navaho, Hopi and Pueblo) reveal similarities with respect to fingerprint indices, frequencies of patterns in all palmar areas, and transverseness of palmar ridges. Comparisons of Seminoles and other North American tribes with the Mayans of southern Mexico and Guatamala show striking differences in pattern frequencies in the thenar/first interdigital area of the palm. Among North American Indians, the frequency varies from 18.49% among Seminoles to 28.5% among Navahoes, whereas all Mayan tribes which have been studied range between 40 and 50%. Pattern frequencies are higher in the thenar/first interdigital area than in the hypothenar area among all Amerindians who have been tested. This trend is the reverse of that found in other racial groups. North, Central and South American Indians are similar with respect to relatively high finger pattern indices, low frequencies of patterns in the hypothenar area, low frequencies of accessory triradii in the interdigital areas and moderately transverse palmar ridges.

Dermatoglyphic characteristics of a population from the central Rhodopes (south Bulgaria)

The finger and palmar prints of a total of 386 individuals (182 males and 204 females) at an age between 10 and 18 years from the region of the villages Petkovo and Banite, situated along the river Malka Arda in the Central Rhodopes, were studied. The following dermatoglyphic traits were analyzed: pattern intensity index (PII), the main line or Cummin's index (MLI), the frequencies of the proximal palmar triradius (t), the true hypothenar patterns (Hy) and the accessory interdigital triradii (AIT). The specific dermatoglyphic complexes after Heet were also determined for the population under study. A peculiarity of this population is the appearance of a clearly expressed Eastern Complex (EC), which accounts for 53.1% in the males and for 48.8% in the females. These values of EC and the calculated dermatoglyphic distances (DD) after Heet show a similarity between the examined population and a number of populations from the Volga region, Northern Caucasus, Middle Asia and Siberia. This similarity could be explained with the preservation of the genetic heritage of the proto-Bulgarians, one of the three main components of the modern Bulgarians.     

Dermatoglyphic patterns in senile dementia of Alzheimer's type

Several reports suggest a genetic relationship between senile dementia of Alzheimer type (SDAT) and Down's syndrome. We have analyzed fingerprints and palmar patterns in an elderly female population comprising a group of 34 patients with probable SDAT, a group of 20 patients with other dementias, and a group of 20 non-demented controls. A bilateral Sydney line was found to be significantly more frequent in the SDAT group than in the two other groups (p less than 0.01, sensitivity 30%, specificity 95%, positive predictive value 91%, negative predictive value 61%). A bilateral Sydney line was as frequent in the SDAT group as in Down's syndrome. The limit value of the index of transversality equal or superior to 31, which is considered as a feature of Down's syndrome, was significantly more frequent in the SDAT group than in the two other groups (right hand p less than 0.05, left hand p less than 0.02). A bilateral discriminant value of this index was also significantly more frequent in the SDAT group than in the two other groups (p less than 0.02), as was an index of transversality higher than 31 on at least one hand (p less than 0.01). In contrast with other reports, we haven't found significantly different frequencies of digital ulnar loops and true hypothenar patterns between the SDAT group and the two others.     

Arches of the hand in reach to grasp

Topographically, the hand is described by its anterior (palmar) and posterior (dorsal) surfaces that encompass a hollow cavity that changes its shape during hand preshaping and grasping according to the object to be grasped. The hollow cavity has been described as consisting of three arches that run in different directions: transverse, longitudinal and oblique, spanning the anterior surface of the hand. Although described anatomically, the modulation in the palmar arches has not been investigated kinematically during actual grasping. In this study, we describe and compare biomechanical formulations of the palmar arch, specifically, the distal transverse and the oblique arches. In addition, we introduce another biomechanical formulation of the palmar arch, called the kinematic transverse arch that takes account of the thenar and hypothenar involvement in arch formation. Hand shape modulation during two natural power-grasping tasks was studied in eight healthy adults. Results showed a significant influence of the overall contribution of thenar and hypothenar movement during hand shape modulation. While there was relatively more thenar contribution during transport shaping, more hypothenar contribution was evident during preshaping and contact shaping-the two phases of grasping during which the hand establishes contact with the object. The advantage of the new formulation is that it better described the contributions from thenar and hypothenar movement to palmar arch formation which may be a more accurate depiction of hand preshaping during grasping.     

A dermatoglyphic study of the Kavalan aboriginal population of Taiwan

By the 1970s, a number of dermatoglyphic studies of Taiwan aborigines (Gaoshan nationality) had been published, however in each only a few dermatoglyphic variables were addressed. Since that time, little new research has been conducted. In this study, we collected and analyzed the dermatoglyphs of 100 individuals of Kavalan, a Taiwan aboriginal population, and we reported a wide range of dermatoglyphic variables including total finger ridge count (TFRC), a-b total ridge count (a-b RC), atd angle and axial triradius percent distance (tPD), and frequencies of fingerprint pattern, palmar thenar pattern, palmar interdigital pattern, palmar hypothenar pattern, and simian line. This study is the first comprehensive dermatoglyphic research of any Taiwan aboriginal population.

Qualitative dermatoglyphic traits as measures of population distance

Thirteen Iranian populations of diverse origin have been analyzed for qualitative dermatoglyphic features utilizing bilateral finger and palmar prints of 3,158 individuals. Bimanual differences were significant for some of the features examined, whereas sex differences were frequently nonsignificant. Interpopulational variation displayed significant heterogeneity for all of the features studied. Distance analysis and constructed dendrograms provided separation between populations in agreement with known ethnohistoric records for hypothenar triradii, and for palmar and finger patterns, but not for the terminations of the D-Line.

A method for subclassifying the interdigital patterns: a comparative study of the palmar configurations

A method for subtyping the interdigital patterns is introduced, which is based upon the direction of the main line terminations as well as the presence of accessory triradii. The palmar patterns of several population samples from our files representing the Caucasians, Negroes, Miconesians and New Guinean groups are evaluted in terms of the introduced calssification and the results demonstrate a number of differences between the major racial groups. In additin, the thenar/I and hypothenar patterns are subtyped according to the classifications of Cummins and Midlo. These data also indicate the inadequacy of the general open/arch, vestige, loop, whorl identification of the plamar patterns. It is hoped that more data will be studied along these lines for establishment of more accurate frequencies among the various racial groups.     

Finger dermatoglyphics of the Tibetans

Finger prints of 156 Tibetan males and 150 females have been analyzed. Whorls are more abundant in Tibetan males (60.24%) than in females (48.67%). The index of pattern intensity shows a higher value in males (15.95) than the females (14.65). The bimanual differences (both in males and females) are not statistically significant for the occurrence of pattern on the digits of the right and left hands. However, the difference between the sexes for the occurrence of patterns on the finger balls, are statistically significant. Ridge counting was done for each finger. On all fingers, Tibetan males have higher ridge-counts than females. The possible tendency for the right hands to possess higher ridge-counts cannot be demonstrated statistically. Tibetans show greater affinity with the Southern Mongoloids in the frequency distributions of pattern types on the finger balls. However, a more detailed dermatoglyphic study of all the Mongoloid populations in South East Asia, Central Asia and Far East would yield information of great value in disclosing the palmar pattern distributions among the Mongoloids.
