Dermatoglyphic studies in affective disorders: an appraisal.

The etiology, nosology, and mode of transmission of affective disorders is still obscure. A number of studies have suggested the division of manic-depressive psychosis into unipolar and bipolar categories with distinct mechanisms of transmission. This study focuses on the role of dermatoglyphics in the study of affective disorders. Dermatoglyphics add a new dimension to the diagnosis, nosology, and understanding of the genetics of affective disorders.

Dermatoglyphics of the Naik Gond.

This paper deals with the finger and palm prints of the Naik Gond, a Dravidian speaking tribe of Chandrapur, Maharashtra. It represents a few dermatoglyphic characters such as pattern types, number of finger triradii, total finger ridge count, main-line index and ab ridge count which have expressed the usual trends of sexual dimorphism. The data have been compared with that of the neighbouring Raj Gond and the Pardhan who share common socio-linguistic traits with the Naik Gond. In dermatoglyphic characters the Naik Gond are found to be homogeneous with the Raj Gond and the Pardhan which lends support to the existing ethnohistoric information.

[Dermatoglyphic studies in primary and secondary hypogonadism].

A dermatoglyphic study was carried out on a group of patients with primary and secondary hypogonadism, the results being compared with a control group of healthy males and females. The analysis of the data reveals that the morphogenesis of the hand skin relie on those patients results from the interaction of the determinative effect of the sexual chromosome, the differentiating effect of the hormonal state and from the eventually suffered intralaterine infection. In this way certain aspects of the etiopathogenesis of the disease are revealed and the genetic value of the dermatoglyphic method is underlined.

[Dermatoglyphics and cancerous diseases].

The dermatoglyphic analysis of finger and palm prints was conducted in oncologic patients living in the same town and in corresponding with respect to the number control groups of inhabitants of the same town that were matched to each patient by the most relevant risk factors. The study was based on 61 dermatoglyphic characters. Using computer pattern recognition programs sufficiently informative subcomplexes of these characters were formed. They permitted to discriminate between ill and control persons.

[Dermatoglyphic indices in assessing the predisposition to occupational fluorosis].

Dermatoglyphic investigations which prove the existence of genetic predisposition to occupational fluorosis in workers of aluminum and criolite plants were carried out. Mathematical methods of pattern recognition were used for the multifactorial analysis. It was found that the complex analysis of ten the most informative dermatoglyphic parameters permits to prognosticate a genetically determined risk of this occupational disease.

Population structure of the Chenchu and other south Indian tribal groups: relationships between genetic, anthropometric, dermatoglyphic, geographic, and linguistic distances.

We describe the genetic structure and interrelationships of nine south Indian tribal groups (seven from Andhra Pradesh and two from the adjoining states of Tamil Nadu and Kerala) using seven polymorphic loci (ABO, MN, RH, PGM, ACP, PGD, and LDH). R matrix analysis indicates that the Andhra Pradesh tribes are clustered and that the Kadar and Irula are genetically isolated from them. This dispersion of populations has been explained by the combination of relatively high frequencies of the alleles RH D and MN M in the Kadar and the relatively high proportions of the allele PGM*2 in the Irula. The Mahaboobnagar Chenchu subgroup is isolated from other Telugu-speaking groups because of high frequencies of the PGM*1 and ACP*A alleles. The regression of mean per locus heterozygosity (H) on distance from the gene frequency centroid (rii) reveals considerable levels of external gene flow among the Lambadi, the Yerukula, and the two Chenchu subgroups and more homogeneity in the Kolam, Koya, Yanadi, Irula, and Kadar. Mantel statistics were used to assess the relative effects of nonbiological processes (i.e., language and geography) on the morphological and genetic patterns of these subdivided populations. The significance of correlations was determined between different data sets (genetic, dermatoglyphic, anthropometric, geographic, and linguistic) at three levels involving nine, six, and five populations. Although multiple correlation analysis reveals significant combined effects of geography and language on genetics, anthropometrics, and dermatoglyphics, highly significant partial correlations suggest strong effects of geography on both anthropometry and genetics. Our analysis indicates that geographic factors have an overwhelming effect on the genetic differentiation of the south Indian tribal groups.

Bilateral absence of maxillary and mandibular second premolars: a clinical, genetic and dermatoglyphic study.

In the report presented here the mode of inheritance pattern of absence of maxillary and mandibular second premolars will be investigated by pedigree analyses and dermatoglyphic studies of a patient who showed the trait and his family members. An 11-year-old male patient with caries with bilateral absence of maxillary and mandibular second premolars was observed. Most of the dermatoglyphic traits observed in the patient were also found in the father and the sister of the patient.

[Constitutional and dermatoglyphic characteristics of children with diabetes mellitus].

A group of Russian children with clinically diagnosed diabetes mellitus were examined using a comprehensive constitutional dermatoglyphic program. Pattern asymmetry was observed in children of both sexes. On the whole the examined population was characterized by reduced incidence of loop patterns and increased incidence of double-delta patterns. In boys the incidence of arches and coils was higher and that of loops lower than in controls, in girls there were no arches and the incidence of radical and ulnar loops was low. Analysis of genetically determined signs, both anthropometric and dermatoglyphic ones, and use of other criteria will help assess the significance of these signs as markers of risk of development of type I diabetes.

Study of finger and palmar dermatoglyphics in primary infertile males.

Finger and palmar dermatoglyphic variations have been studied in 160 diagnosed primary infertile males (111 clinically abnormal primary infertile males and 49 clinically normal primary infertile males). It has been observed that loops occur most frequently in primary infertile males. Arches are found to be absent on digit IV and V. Among the clinically normal infertile males the mainline formula 7.5.5--succeeds 11.9.7--instead of 9.7.5--in the order of preponderance. Bilateral and inter-group differences among clinically abnormal and normal infertile males have been found to be statistically non-significant for finger and palmar comparison. The present findings are compared with the result on finger and palmar dermatoglyphics of controls (130 Punjabi males of Delhi). Clinically normal infertile males show statistically significant differences in the occurrence of various pattern types of finger balls when compared with controls. Similarly, clinically abnormal as well as normal primary infertile males reveal statistically significant results in the occurrence of patterns in the hypothenar and Thenar/I interdigital area of palms when compared with controls.

Finger dermatoglyphics in Delta de l'Ebre: a Mediterranean Spanish population.

Pattern types and quantitative finger dermatoglyphics have been analyzed in a Spanish population samples (141 males, 200 females) from the Mediterranean coast. For both dermatoglyphic traits sexual and bilateral differences were tested by means of Chi-square and Student's t-test. Concerning the pattern types the male samples show an intermediate position in the Spanish variation range, whereas the female sample differs from all the populations compared. In regard of the quantitative values the Delta de l'Ebre population is within the general range of ridge counts described for other Iberian samples. This is valid for both sexes.

Dermatoglyphic patterns of patients with rheumatoid arthritis.

Finger tip and palmar dermatoglyphics were studied in 31 patients (22 females and 9 males) with rheumatoid arthritis (RA) and 38 matched controls (20 females and 18 males) from North India. While not many differences were observed in palmar patterns, a low ending of line A was found on both hands of two patients. Finger tip patterns were significantly different in patients compared to controls. No association with any dermatoglyphic feature and HLA antigens was observed.

Robinow syndrome: with special emphasis on dermatoglyphics and hand malformations (split hand).

Fourteen cases of Robinow syndrome are described with special emphasis on dermatoglyphics and hand malformations (split hands were detected in two, ectrodactyly with nail hypoplasia in one and hypoplastic extra middle finger in another one). Dermatoglyphic studies were performed on ten cases. Increased whorl patterns of the finger tips and a single large palmar hypothenar whorl pattern associated with distally displaced axial triradii were detected. These have not previously been described.

[Correlation of dermatoglyphic and cellular immunity parameters in children with early stage of primary tuberculosis].

Immunological status and dermatoglyphic characteristics were compared in 55 children aged 4-14 with a turn in tuberculin reactions. A correlation was established between genetic and immunological factors, this pointing to the fact that dermatoglyphics is a component of genotype indicative of natural resistance of children to tuberculosis. Synchronization between immunological and genetic values is less intensive in children with immunological disorders against those without them. The findings support the hypophysis on an evolutional role of M. tuberculosis as natural selection factors as well as setting up genetically determined mechanisms of natural resistance to tuberculosis.

Dermatoglyphic analysis of La Liébana (Cantabria, Spain). 2. Finger ridge counts.

The results of univariate and multivariate analyses of the quantitative finger dermatoglyphic traits (i.e. ridge counts) of a sample of 109 males and 88 females from La Liébana (Cantabria, Spain) are reported. Univariate results follow the trends usually found in previous studies, e.g., ranking of finger ridge counts, bilateral asymmetry or shape of the distributions of the frequencies. However, sexual dimorphism is nearly inexistent concerning finger ridge counts. This lack of dimorphism could be related to certain characteristics of the distribution of finger dermatoglyphic patterns previously reported by the same authors. The multivariate description has been carried out by means of principal component analysis (with varimax rotation to obtain the final solution) of the correlation matrices computed from the 10 maximal finger ridge counts. Although the results do not necessarily prove the concept of developmental fields ("field theory" and later modifications), some precepts of the theory are present: field polarization and field overlapping.

[Bilateral symmetry of the dermatoglyphic characteristics in Down's syndrome].

Dermatoglyphic traits were analyzed in 132 patients with Down syndrome. The level of bilateral symmetry of dermatoglyphic indices in these patients was found to be higher than in normal people (control). By this parameter, patients with Down syndrome showed lower intragroup variation than the control group. It is suggested that such difference is due to a more primitive developmental pathway.

Congenital hypodontia: a pedigree and dermatoglyphic study.

The dermatoglyphs and the pedigrees of 11 male and 10 female, a total of 21 patients with congenital hypodontia (CH) were investigated. The dermatoglyphics of the patients were compared with those of 250 male and 250 female control cases. There were more arches on the finger-tips of the patients with absence of the lateral incisors, absence of the second premolars and a total patients with CH. The patients with absence of the lateral incisors had more palmar ll and plantar lll loops and p triradii. The patients with absence of the second premolars had more H and H loops, P triradii and plantar ll loops. A total patients with CH had more palmar ll and plantar lll, IV loops and p and z triradii. The pedigrees of the patients with both absence of the lateral incisors and the second premolars showed that the inheritance patterns of both conditions would seem autosomal recessive.

[Characteristics of the dermatoglyphics of the hand in congenital deaf-mutism].

Differences in a number of dermatoglyphic signs in patients with endogenous forms of the disease were found when analysing dermatoglyphics among 535 patients with congenital deaf-mutism. These differences may be of certain significance for differentiation between exogenous and endogenous forms of deaf-mutism, that is of great importance for a medico-genetical consultation with respect to progeny prognosis.

[Forensic medical criteria of relationship according to the dermatoglyphic traits of the foot].

Inheriting of 55 dermatoglyphic signs of the soles are analyzed using Cummins and Midlo's method (1962) in 100 families (father, mother, one or two children). For the first time in Russian forensic medicine quantitative criteria of familial similarity by the complex of dermatoglyphic signs of the soles have been defined. The inheritance of skin patterns on the toes is governed by the same regularities as on the hands and does not depend on the localization of patterns (right or left side), number of the toe, and sex. The authors detected and investigated the possibility of inheritance of skin patterns from a homologous toe or area of the sole of a parent by a child in whom this pattern occurs on the homologous toe or area of the sole (mirror symmetry) or on one of the adjacent toes or the same sole. The possibility of referring a child to a specific couple of parents on the basis of a single complex pattern formalized according to the devised method has been validated for the first time.
