Abstract

Introduction: Insulin-dependent diabetes mellitus (IDDM) or type 1 diabetes is an organ-specific autoimmune disease that caused by destruction of insulin-producing beta cells of the pancreas. Etiology of this disease is still unknown. It is seen that genetic and environmental factors play an important role for susceptibility to develop type 1 diabetes. The relationship between HLA associated factors and susceptibility to IDDM disease, was reported by several investigators. Also, some studies show that dermatoglyphics is associated with type 1 diabetes. However, it is maybe there is an association between HLA and dermatoglyphics inpatients'with type 1 diabetes and these characteristics could be applied for diagnosis of disease.
Materials and Methods: In this study, the prevalence of HLA (with using standard microlymphocytotoxicity method) and dermatoglyphics determined in 30 Iranian patients with IDDM and 30 normal healthy controls with similar ethnic background and the same geographical area.
Results: A significantly higher frequency of HLA-DQ, A2, DR3 and DQ2 were found in IDDM cases compared to the controls. The results obtain from dermatoglyphics showed that line ab was reduced in male and female type 1 diabetes. The reciever operating chractristics curve showed that the positive point for lines ab in right and left hands were 34.7 and 35.25, respectively.
Discussion: There is no association between HLA and dermatoglyphics.
With considering of genes encoding of HLA separated from genes determining dermatoglyphics, HLA typing and dermatoglyphics seem to be interesting tools for genetic studies related to type 1 diabetes. Further studies are recommended in order to provide more insight into the susceptibility to this disorder.

Abstract

Introduction: One of the severe forms of affective disorders, defined in DSM-IV-TR, is bipolar disorder type1. This is a psychotic disease that coexists with structural and biochemical changes of CNS. It is probably under influence of environmental and/or genetic factors. Finger and hand prints are formed during the late first and second trimester of fetal development, and then remain unchanged. There are some suggestions that disturbance in dermatoglyphic patterns probably are in relation with appearance of bipolar disorder. It seems that this disturbance is appeared at the first and second trimester of fetal development, which is a critical period for CNS growth. This study is done to investigate the dermatoglyphic patterns in bipolar disorder. Materials and Methods: This is a case-control study in which we have studied the dermatoglyphic changes in 30 bipolar disorder patients and compared to those of 72 healthy controls. The χ2 test was used for quantitative and T-test for qualitative data analysis. Results: Results showed that TABRC in patients was decreased in comparison to healthy people but this decrease was not significant. Regarding the type of patients, fingerprints, Loop and Whorls forms were heterogenous and were significantly different in comparison to control group (p=0.001, p=0.003). Conclusion: It seems that dermatoglyphic patterns can be an interesting and probably suitable procedure in determining the prognosis of bipolar disorder type 1 and other psychiatric disorders.

Abstract

Dermatoglyphic patterns are formed during the first and the second fetal development trimesters and they remain unchanged afterwards. At the end of the fourth month of fetal development, fingertips are formed along with brain and other derived ectodermia developments. In the 19th century, the mystery of human fingertips was discovered, and it was realized that fingertips consist of tiny network lines in the epiderms of the skin, and are exclusive to every individual, even to twins. In this study, through library research, by reviewing quantitative and qualitative dermatoglyphic patterns, the miracle of fingertips was considered based on Quran and Islamic commandments. Much research has been done comparing individual dermatoglyphic patterns of hands among various races, and the quantitative and qualitative relationship between dermatoglyphic patterns and diseases such as schizophrenia, nervous disorders, Down syndrome, diabetes I, Alzheimer, multiple sclerosis, congenital spinal abnormalities, and psoriasis disease has been shown. Accordingly, finger prints are used for identifying individuals, detecting criminals, and studying disease of genetic background. They can also be used as clues in determining the etiology of diseases. Fingertip sign is unique for every individual. Quran, in response to those who deny the resurrection after decomposition of the body and bones (Saffat, 37: 16), declares that Allah almighty, is not only capable of recreating them, but also is able to make human fingertips again (75: 3-4). The study shows the importance of human’s fingertips as the miracle of human creation, and reveals why Quran emphasizes on them as one indication of resurrection.

Abstract

Background: Essential hypertension which affects 1 billion people worldwide is a multifactorial disorder and influenced by genetic and environmental factors. In human at about 14th week of pregnancy, sweat gland anlagen appear at uniform intervals along the apices of the epidermal ridges. Once the pores of sweat gland form on the ridge, they are fixed at that location. Considerable amount of researches have shown that pores do not disappear, move or spontaneously generate over time. The goal of the present study was to examine whether there is a relationship between the number of palmar sweat gland pores and hypertension condition. Methods: By applying a digital microscope, the number of palamr sweat gland pores were counted in a circle area (12.5 –16.8 mm2) of certain anatomical regions (a, b, c triradials and fingers) in 75 hypertensive and 55 normotensive females. The average age of all patients was 60 years and the average age of all controls was 49 years and all patients had a familial background of hypertension. Results: Statistical analysis of the data showed that the mean count of sweat gland's pores on fingers and b triradial in hypertensive group was significantly lower than normotensive subjects. Conclusion: In conclusion, the results obtained from the present study indicate that there is a meaningful relation between the numbers of fingertip sweat glands pores and hypertension. This finding can be used for the prognosis and early detection of hypertension in susceptible persons, particularly among those with a familial background.

Abstract

Introduction: Dermatoglyphic is a science that study the lines in the skin of the palms and fingertips properly. In some studies, the relationship between dermatoglyphic patterns with some diseases has been proven Arthritis Rheumatoid is a chronic inflammatory disease with autoimmune pathogenesis. The aim of this study was to investigate the qualitative and quantitative characteristics of dermatoglyphics in people with rheumatoid arthritis compared to the control group.
Methods: This case-control study was conducted on 50 patients with rheumatoid arthritis and 50 people in the control group living in Mashhad. The fingerprint was recorded by the scanner.  The distribution of the frequency of fingerprint patterns, including Arch, Loop and Whorl, along with the counting of fingerprint lines in both groups was investigated. Finally, the obtained data were analyzed using ANOVA and X2 tests.
Results: According to the results, the maximum frequency of dermatoglyphic patterns in both hands was related to the ulnar loop type. After that, in the patient group, simple Whorl patterns and double Whorl patterns and in the healthy group, double Whorl patterns and simple Whorl patterns were the most frequent. Between the average finger ridge count in the right hand of healthy people with the right hand of patient’s people and the left hand of healthy people with the left hand of patient’s people showed a significant difference in the error level of 0.05.
Conclusions: It seems that this difference can be used as a biological diagnostic marker to screen people prone to rheumatoid arthritis. This information in prognosis of psychological, medical and therapeutic plans, issues related to anthropology and social sciences can also be useful.
