A contribution to genetic etiology of complex regional pain syndrome type I (algodystropy syndrome) based on quantitative analysis of digitopalmar dermatoglyphics in sixty men.

The patterns of the ridges of the skin of the fingers and palms were determined in sixty men with complex regional pain syndrome (type I) as a measure of disease prevention. The study included 25 dermatoglyphic traits: number of epidermal ridges on all ten fingers; their sum for five and ten fingers; four traits on both palms, i.e. between a-b, b-c and c-d triradii; atd angles: and their bilateral sum. The data obtained were compared with those recorded in a control group of 200 pairs of imprints of phenotipycally healthy male adults from the Zagreb area. Statistically significant difference from control values were found in 12 dermatoglyphic variables, including an increased sum of ridges on nine fingers (except for left second finger pad), and total sum for five and ten fingers. These findings suggested the polygenic system responsible for development of dermatoglyphics to be identical with some polygenic loci for the onset of algodystrophy syndrome, which might prove useful in disease prevention (e.g., taking fingerprints following a trauma and before rehabilitation), and to facilitate identification of risk groups, and thus the treatment for this longterm and yet obscure syndrome.

Dermatoglyphs and brachial plexus palsy.

Perinatal brachial plexus palsy (PBPP) is a handicap quite commonly encountered in daily routine. Although birth trauma is considered to be the major cause of the defect, it has been observed that PBPP occurs only in some infants born under identical or nearly identical conditions. The aim of this study was to test the hypothesis of genetic predisposition for PBPP. It is well known that digito-palmar dermatoglyphs can be used to determine hereditary roots of some diseases. Thus, we found it meaningful to do a study analysis of digito-palmar dermatoglyphs in this disease as well, conducting it on 140 subjects (70 males and 70 females) diagnosed with PBPP. The control group was composed of fingerprints obtained from 400 adult and phenotypically healthy subjects (200 males and 200 females) from the Zagreb area. The results of multivariate and univariate analysis of variance have shown statistically significant differences between the groups observed. In spite of lower percentage of accurately classified female subjects by discriminant analysis, the results of quantitative analysis of digito-palmar dermatoglyphs appeared to suggest a genetic predisposition for the occurrence of PBPP.

[Characteristics of digital and palmar dermatoglyphics in people of different ages living in the territory of the Ukrainian Polesie].

Examination of dermatoglyphs in people aged 50-103 living in the territory of the Ukrainian Polesie has revealed age differences in some indices of dermatoglyphics: total crest count, palmar angle, character of the cutaneous pattern of fingers. It assumed that these differences have arisen as a consequence of selection of persons characterized by high reliability of the genotype functioning. The data obtained permit supposing that it is possible to use dermatoglyphics for determining hereditary predisposition of people to longevity.

[Dermatoglyphic characteristics in hereditary ichthyosis].

Examination of 530 dermatoglyphic patterns of the palms and fingers in 265 patients with 5 nosologic forms of hereditary ichthyoses (autosomal dominant ichthyosis vulgaris, X-linked, congenital, lamellar, epidermolytic ichthyoses) have revealed significant differences in the pattern intensities and in the incidence rate of certain types of these patterns, associated with this or that form of ichthyosis; abnormalities in the flexor wrinkles of the ridge skin have been observed in all the studied forms of the disease, except the X-linked condition. The studies have revealed an abnormal roughness of the papillae on the epidermal ridges in epidermolytic ichthyosis and an obliterated dermatoglyphic pattern in lamellar ichthyosis. The detected changes in the ridge skin and the dermatoglyphic phenotypes may be useful for the differential diagnosis of these conditions.

[Palmar dermatoglyphics. Analysis carried out on 315 subjects of western Sicily].

The study of dermatoglyphics is one of particular diagnostic interest in many diseases, especially in the identification of some chromosomal aberration syndromes. The frequent occurrence for observation of this pathology and the need for comparison of the relevant dermatoglyphics with those of an adequate control group, caused us to carry a dermatoglyphic analysis of our population. We examined 315 normal subjects (147 males and 168 females) of Western Sicily.

[Use of complex assessment of dermatoglyphic signs for prediction of the risk of development of occupational diseases].

Dermatoglyphic investigations conducted by the authors made it possible to demonstrate a genetic predisposition to occupational diseases, in particular, to silicosis and silicotuberculosis. Methods based on the mathematical theory of pattern recognition were used for multifactor analysis of the data. It was shown that complex evaluation of 10 dermatoglyphic indices gave a reliable prognosis of the risk of the above two kinds of disease due to silica dust. The dermatoglyphic patterns which predict predisposition to simple silicosis or to silicotuberculosis were found to differ significantly.

Dermatoglyphics in the virilizing polycystic ovary syndrome.

Quantitative and qualitative characteristics (form and orientation of the digital patterns, total digital ridges count, delta index, form and regional distribution of palmar patterns, palmar flexion creases, palmar delta index, atd angle, the direction of the A, B, C, and D palmar lines and the number of crests between the a, b, c, and d triradii) of digito-palmar dermatoglyphics in 33 women with virilizing polycystic ovary (VPO) were studied. The selection was made on the basis of the clinical examination and a complex bio-hormonal exploration of female patients with pilar virilism hospitalized in or treated at the outpatient clinic of the "C. I Parhon" Institute of Endocrinology between 1975 and 1984. The control lot was made up of 100 females and 100 males, clinically healthy, originally from various rural and urban areas in Romania. It was found that the VPO women come within the range of variability of the normal, with some dermatoglyphic peculiarities characteristic of the VPO syndrome; i.e., a lower total digital ridges count, and fewer ridges between the triradii at the basis of the fingers. Qualitatively, there is a preponderance of the loop-like digital patterns, especially those with radial orientation and palmar, compared to the normal, the VPO women present more frequently patterns in the interdigital space II. Palmar flexion lines indicate in VPO women a higher incidence of palmar transversal sulcus variants as compared to normal women. The existence of similar dermatoglyphic peculiarities both in VPO and in adrenogenital syndrome supports the hypothesis that the ovarian hormonogenesis disorders in the VPO syndrome may be genetically determined through an enzymatic defect.

[Dermatoglyphics in children and adolescents suffering epilepsy].

A dermatoglyphical study was conducted on 393 children and adolescents suffering from different forms of epilepsy. The group of epileptic patients compared to normals demonstrated more frequent existence of the transversal sulcus, less symmetricity on digital patterns. The authors distinguished correlations between dermatoglyphical features and a form of epilepsy, type of a course and pathogenic forms. The obtained data testify to a certain diagnostical and prognostical value of dermatoglyphical features.

Comparisons of dermatoglyphic patterns in monochorionic and dichorionic monozygotic twins.

The data presented here indicate that different influences affect dermatoglyphic pattern development in MC-MZ and DC-MZ twins. Only five of 84 variables had significant mean differences but their clustering suggested a real difference in mean placement of the atd angle. Nineteen of 84 variables had significantly different within-pair mean squares for the two twin types. Larger numbers of twins will be required to obtain accurate estimates of the magnitude of the dermatoglyphic differences between MC-MZ and DC-MZ twins. Studies of dermatoglyphics in MC-MZ and DC-MZ twins are important to the understanding of factors which influence early embryonic development and when better documented may provide a mechanism for retrospectively diagnosing placental type of MZ twins.

[Morphologic and dermatoglyphic aspects of Klinefelter 47,XXY syndrome (author's transl)].

The author described 20 personal cases of Klinefelter's syndrome, from among those referred to the Institute of Medical Genetics for cytogenetic confirmation of the clinical diagnosis. In the first instance, in relation to the morphological aspects, the author carried out a historic and aetiological review of the syndrome, estimated its incidence and described the clinical and endocrinological symptomatology, also the testicular histology. She then outlined the differential diagnosis and the treatment envisaged for these cases. After giving a clinical description and details of the anthropobiometric measurements of these 20 patients, the author analysed the morphograms established on the Decourt-Doumic graphs. According to this schema, and in relation to the normal, patients suffering from Klinefelter's syndrome can be distinguished by four different constitutional types. All these four varieties can, together with testicular atrophy, evoke this chromosomal aberration. Only a karyotype and/or a sexual chromatin test could confirm the presence of a Klinefelter's syndrome. Secondly, a dermatoglyphic analysis of 9 patients available for this examination is given. After discussing the history, embryogenesis and heredity of finger prints, the author compared her results with those previously obtained in other studies. In conformity with these, she observed a decrease of TRC, of the a-b count and of the a-t-d angle. In addition, these patients present an increase in the number of accessory triradii a' and d', as well as an absence or an abortive state of triradius c, an absence of thenar configurations and an increase in those of the interdigital space II. Whilst many dermatoglyphic characters in the Klinefelter's syndrome differ but little from the normal, some of them appear, however, to be specific. Consequently, dermatoglyphic examination, especially in the case of a difficult differential diagnosis, can be a great help to the clinician and the geneticist.

Intra-familial correlations of dermatoglyphic traits in South Sinai Bedouins.

Correlation coefficients for some dermatoglyphic traits of the Muzeina Bedouins of South Sinai were determined in sib-sib, father-son, father-daughter, mother-son and mother-daughter comparisons. From among approximately 3000 members of the tribe, 60 male sib-sib pairs and 33 parental pairs, each with one son and one daughter, were selected for examination. The dermatoglyphic traits included finger pattern types, ridge counts with their intra-individual variability and bilateral asymmetry, and the incidence of palmar patterns. In such a small, biologically isolated and consanguineous population, the correlation coefficients for the diverse dermatoglyphic traits are expected to show some peculiarities. In general, we found them to be lower than in other populations. The difference is small for the complex traits with a multifactorial genetic determination, and more pronounced for the traits with a simpler genetic base. With diminution in the number of genes participating in the realization of a trait, the father-mother correlations increase owing to the intense consanguinity.

Dermatoglyphics in Saethre-Chotzen syndrome: a family study.

The dermatoglyphic findings in a Cuban family with the Saethre-Chotzen syndrome are reported. The family consisted of the parents who were first cousins and their three children. A new classification of zygodactylous patterns was used. Characteristic dermatoglyphic patterns which appeared in these cases were representative of the syndrome. Dermatoglyphics also helped to discover minor expressions of syndactyly and showed that all the members of the family had zygodactylous patterns on palms and soles.

[Hand dermatoglyphics in patients with isolated triphalangia and Holt-Oram syndrome].

A comparative analysis of dermatoglyphic prints of patients with the Holt-Oram syndrome and isolated triphalangeal thumbs was performed with control dermatoglyphics. A specific feature of the syndrome is a change in the main palmar lines and their termination on the radial border of the hand not only in the absence of the thumb but also in the case of formation of the abortive xT-line, its radiants, and the axial triradius. This trait may be considered diagnostic for the Holt-Oram syndrome. Cases of triphalangeal thumbs with preaxial polydactyly do not reveal significant changes in dermatoglyphic patterns and appear to result from partial duplication of the thumb. An isolated triphalangeal thumb may be the result of an atavistic development of homeotic transformation of the thumb.

Genetic loadings in schizophrenia: a dermatoglyphic study.

Finger and palmar dermatoglyphics of 120 male and 120 female schizophrenics with and without a family history of schizophrenia in first-degree relatives were studied in the northwestern part of India. Patients were selected according to specific diagnostic criteria. Significant dermatoglyphic differences were observed for fingerprint patterns, total finger ridge counts and 'atd' angle between the schizophrenics with and those without a positive family history of schizophrenia, suggesting a strong "genetic loading" (i.e., hereditary factors) in familial cases of schizophrenia. Dermatoglyphic features of isolated schizophrenics also significantly differed from those of controls, thus indicating the involvement of genetic factors in the etiology of schizophrenia.

Dermatoglyphics in cleft lip and cleft palate anomalies.

Dermatoglyphic characteristics of sixty nine cases of cleft lip with or without cleft palate and twenty eight isolated cleft palate cases were evaluated for digital patterns, interdigital patterns, palmar simian crease and sydney line, and model types of C- and D-line terminations. Increased frequency of ulnar and radial loops than the arches and whorls was observed in cleft lip with or without cleft palate patients compared to controls. Interdigital patterns were less frequent in cleft lip and cleft palate patients. Simian crease and Sydney line were more common in patients than in controls. Model types of C- and D-line terminations showed variations in patients and controls. Wider 'atd' angle (more than 30 degrees) and dermatoglyphic asymmetry were noted in the patient groups. The findings suggest the dichotomy or heterogeneity of cleft lip and cleft palate anomalies. The role and utility of dermatoglyphics in genetical etiology of congenital defects were emphasized.

Local, hypoplastic type of amelogenesis imperfecta: a clinical, genetic, radiological and dermatoglyphic study.

A patient and her family members showing X-linked dominant form local, hypoplastic type of amelogenesis imperfecta (AI) were investigated from view-point of their teeth, clinical, genetic, radiological and particularly dermatoglyphic findings. It was suggested that it might be a close relationship between the intra-uterine development of both AI and unusual dermatoglyphs originated from the same layer, ectoderm and an X-linked dominant gene could determine both abnormal teeth and unusual dermatoglyphic characteristics in questions.

[The dermatoglyphic test in the detection and prevention of different genetic diseases].

The paper contains a study of the dermatoglyphics concerning a group of 100 women, mothers having at least one pluri-malformed child in the family and who are originally from the department an county of Iaşi. An increased incidence of the most important and the gravest digital and palmar dermatoglyphic abnormalities (dermatoglyphoses) whose presence in the table of the mothers apparently healthy from the somatic, physiological and neuropsychological point of view represents signals (stigmata) of their progenies' diseases has been observed to occur. The number of these dermatoglyphoses in the digito-palmar table of one and same carrier increases when the degree of somatic, physiological and neuropsychic degenerescence of these children is more emphasised, fact that justifies the employment of the dermatoglyphics as a test for the discovering and the prophylaxis of hereditary diseases.

[Dermatoglyphic patterns in celiac disease].

In 1990 a project was performed in Israel in which the authors reported a higher frequency of whorls and a lower frequency of ulnar loops in the dermatoglyphic pattern of children with celiac disease than in children belonging to control group. Based on these findings we carried out a similar study with our local population. Thirty six celiac children, their parents and siblings had their fingerprints analysed and compared to a control group matching for age, sex and race, in order to assess the efficiency of this method for the diagnosis of celiac disease. A statistically significant higher frequency of whorls and arches was found in celiac children than in control group (whorls = 40.6%, arches = 11.7%; whorls = 30.3%, arches = 5.0%, respectively) as well as a strong correlation between the dermatoglyphic pattern of the parents and their celiac children. There was also a statistically higher frequency of whorls > = 4 in celiac children (55.6%) than in controls (30.6%). The conclusion is that the dermatoglyphic pattern analysis can be used as a complementary data. Due to its low sensitivity (55.6%) and specificity (69.4%) considering the presence of four or more whorls, it is not useful as a screening or as a method itself, for the diagnosis of celiac disease.
