Study of the patterns of the epidermal ridges can also serve as an aid to the diagnosis of many diseases, particularly those caused by chromosomal abnormalities. As Non-Insulin Dependent Diabetes Mellitus (NIDDM) has genetic predisposition, dermatoglyphics can be used to find out possibility of occurring of disease in future. Material & Method: The dermatoglyphic patterns of 100 patients (Cases) (50 male, 50 female) of NIDDM between age group of 40-75 years have been taken. Similarly 100 normal healthy individual (50 male, 50 female) without NIDDM of the same age group have been included in the study as controls. The dermatoglyphic prints in present study have been taken by Ink method. atd angle was measured. Results: Mean atd angle (°) was higher in right hand of cases (43.87°) than controls (40.81°), with P value was 0.002(<0.01). So, it was statistically highly significant while Mean atd angle (°) was higher in left hand of cases (41.58°) than controls (40.27°), with P value was 0.09. So, it was not statistically significant. Conclusion: From the present study, it can be concluded that there is significant difference in atd angle between NIDDM patients and normal individuals. atd angle can be helpful to find out high risk individuals for NIDDM. Key words: dermatoglyphics, atd angle, non-insulin dependent diabetes mellitus INTRODUCTION Dermatoglyphics, “derma-skin and glyphe-curve”, is the name given to the study of the ridge patterning of skin of the fingers, palms, toes and soles [1]. The epidermal ridges correspond to an underlying interlocking pattern of dermal papillae, an arrangement which helps to anchor the two layers firmly together. The patterns of dermal papillae determine the early development of epidermal ridges [2]. Diabetes mellitus is a non-communicable disease and significant public health problem. Among all types of Diabetes Mellitus, Non-Insulin Dependent Diabetes Mellitus (NIDDM) is predominant in India. NIDDM results from an interaction between genetic and environmental factors. Family history is a strong risk factor and it indicates genetic predisposition [3]. Dermatoglyphics is a genetically based study, less costly and easy to do. As NIDDM has genetic predisposition, dermatoglyphics can be used to find out possibility of occurring of disease in future. In past, some studies have been done to evaluate any correlation between dermatoglyphics and NIDDM. There are some positive findings in those studies. Therefore in present study, an attempt has been made to find out the association between dermatoglyphics and NIDDM. MATERIAL AND METHODS Original Article
