Hand dominance and bilateral asymmetry in the structure of the second metacarpal
Bilateral asymmetry in the structure of the second metacarpal was examined in relation to functional hand dominance in a large, clinically nonselected, healthy population sample from the Baltimore Longitudinal Study of Aging. Bilateral bone measurements were made from anteroposterior hand radiographs of a total of 992 individuals, 609 males and 383 females, with an age range of 19–94 years. Hand dominance was determined on the basis of personal i…
A longitudinal study of osteoarthritis of the hand
Osteoarthritis is the most ubiquitous rheumatic disease worldwide. Although its prevalence in various populations has been well documented, few studies have evaluated the longitudinal radiographic progression of the disease, especially as it is expressed in the interphalangeal joints of the hand. In this longitudinal study, left hand-wrist X-rays of 386 white male participants of the Baltimore Longitudinal Study of Aging followed for at least 5 y…
The effect of a pattern in palmar interdigital II on a ‐ b ridge count in black and white down syndrome cases and controls
An unconfirmed study by Fang (Ph.D. thesis, Univ. of London, 1950) in Britain showed that individuals with Down syndrome had lower total a ‐ b ridge counts in palmar Interdigital area II (ID II) than a group of controls. This study compares 603 white Down syndrome cases and 93 black Down syndrome cases with 668 white and 402 black controls. Our results confirm those of Fang in that the Down syndrome cases in both racial groups had lower total a ‐…
Bone mass in Guamanian patients with amyotrophic lateral sclerosis and parkinsonism‐dementia
Bone mass, as assessed by measurements of total subperiosteal diameter and medullary width of the second metacarpal bone on hand‐wrist radiographs, was evaluated for 31 Guamanian patients (15 males, 16 females) with amyotrophic lateral sclerosis (ALS), 67 patients (39 males, 28 females) with parkinsonism‐dementia (PD), and 66 (34 males, 32 females) nonaffected Guamanian controls. Comparisons between the two disease groups and between each disease…
Toe and plantar dermatoglyphics in adult American Caucasians
The scarcity of information on control data of toe and plantar dermatoglyphics led us to undertake this study of adult American Caucasians. Toe and sole prints of 168 male and 83 female participants of the Baltimore Longitudinal Study of Aging were analyzed. Toe pattern frequencies demonstrate that fibular loops are the most prevalent pattern on the toes in both males and females. Pattern distribution by digit shows that arches are most often loc…
Markers of genetic variation among the Waorani Indians of the Ecuadorian Amazon headwaters
Until recently, the Waorani Indians of Ecuador's Amazon headwaters maintained a fierce resistance to all intruders into their territory, and as a result of their actions and reputations a population of 600 people controlled a very large territory (about 8,000 square miles). The isolation of the Waorani has resulted in a large linguistic and genetic distance from their neighbors. Our survey of red cell enzymes, immunoglobulin allotypes, and dermat…
Cortical bone loss and measurements of the second metacarpal bone
Hand‐wrist radiographs from 326 Guamanian children (180 boys and 146 girls) were evaluated for total width, medullary width, length, and combined cortical thickness of the second metacarpal. Bone measurements as well as standing height and weight were compared to similar published data from U.S. mainland black, white, and Mexican‐American children. The results demonstrated that the second metacarpal bones of Guamanian boys and girls of all age gr…
Studies of endemic cretinism in Papua New Guinea
We have tested the hypothesis that the abnormal development of the central nervous system seen in endemic cretinism might be accompanied by concurrent abnormal dermatoglyphic patterns. We compared digital and palmar dermatoglyphics of normal individuals and endemic cretins inhabiting the Huon Peninsula of Papua New Guinea. The population sampled from the Irumu River Valley included 118 males and 114 females with 22 male cretins and 23 female cret…
Cortical bone loss and measurements of the second metacarpal bone. I. Comparisons between adult Guamanian Chamorros and American caucasians
The amount of radiographically detectable cortical bone, as determined by measurements of the second metacarpal, was evaluated in 42 male and 45 female Guamanian Chamorros and compared with the degree of bony demineralization in U.S. Caucasians participating in the Baltimore Longitudinal Study on Aging of the Gerontology Research Center. All Chamorros were individually matched to the Caucasian participants for age, sex, and menopause status. Cham…
Dermatoglyphic assessment of the genetic relationships of native American populations
Genetic distance techniques and cluster analysis were used to determine which dermatoglyphic parameters were most useful in assessing genetic relationships between native American populations. The dermatoglyphic parameters used for this analysis were those most completely reported in the papers examined in a literature survey we had carried out previously, and include digital patterns, modal types of the C‐line and D‐line terminations, and palmar…
Bilateral asymmetry in bone measurements of the hand and lateral hand dominance
Two hundred thirty–five (235) normal male participants of the Baltimore Longitudinal Study were classified as right handed, left handed, and ambidextrous on the basis of their grip–strength performance. Their left and right hands were also radiographed and the measurements of the second metacarpal bones were evaluated on the basis of hand dominance. The results indicated that, as a rule, the right hand measurements are higher than those of the le…
Inheritance studies of c-t and a-d intertriradial distances on the palm by means of twin pair analysis
The dermatoglyphics of the Maprik sub-district of the Sepic district of New Guinea
The dermatoglyphics of American Caucasians
Digital and palmar dermatoglyphics were collected from 360 male and 360 female seven year old Caucasians from the greater Boston area. All participants were screened and found to be free of minor anomalies or chronic diseases. All individuals with I.Q. scores below 70 were also excluded. The results were presented in such a way as to give information on bilateral symmetry as well as overall frequencies of the various dermatoglyphic features. The …
The dermatoglyphics of the Elema people from the Gulf district of Papua New Guinea
The present report deals with the digital and palmar dermatoglyphics of the Elema peoples from the Gulf District of Papua New Guinea. The samples involved 91 males and 134 females from the areas of Iokea, Sepoe and Karama. The Elema dermatoglyphics, compared to those of other peoples in New Guinea, were found to have a high pattern intensity index and frequency of whorls, and the highest frequency of ulnar type C line, complete simian creases and…
The dermatoglyphics of American Negroes
Digital and palmar dermatoglyphics of 184 male and 224 female normal American Negroes were evaluated for digital patterns, digital ridge counts, palmar patterns, palmar main line terminations, accessory triradii and palmar creases. All subjects were seven year olds examined and found free of chronic or other genetic diseases. The results were presented for the left and right hand for the most part comparable to those of the African and other Amer…
Dermatoglyphics of the Micronesians from the Outer Islands of Yap
A method for subclassifying the interdigital patterns
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 group…
Polymorphism of the C line of palmar dermatoglyphics with a new classification of the C line terminations
The terminations of the C line of the palm were classified into four modal types according to the direction of their path. These are (1) Ulnar type with 3, 4, 5′, 5′′, 6 or 7 terminations; (2) Radial type with terminations in the palmar areas 9, 10, 11, 12, or 13; (3) Proximal type representing the terminations X, x, or 8; and (4) Absent type where no c triradius is present. The frequency of these four modal types exhibits strong racial variation…
Dermatoglyphics and flexion creases of the Cypriots
A comparison of the dermatoglyphic features of 60 Greek Cypriots from the coastal region of Yialousa and 60 from the isolated mountainous region of Troodos showed significant differences only in the frequencies of digital whorls and loops in the left hands of the males and in the frequencies of Thenar/I patterns in the palms of the females. All other comparisons produced nonsignificant differences. The overall dermatoglyphic similarities are in c…
Blood group investigations on the Carolinians and Chamorros of Saipan
A comparison of the frequencies of blood groups, haptoglobins, and hemoglobins of Chamorros and Carolinians of Saipan showed significant differences in the Rh, MNS, P, and Kidd systems. The differences were not of sufficient magnitude to exclude the possibility that the two groups were of the same ethnic origin. Thalassemia of the β variety was detected in two Chamorros, indicating the presence of this complex in Micronesians as well as in other …
