Study of finger print patterns in leprosy.

Area of Science:

• Dermatoglyphics
• Medical Genetics
• Infectious Diseases

Background:

• Leprosy, a chronic infectious disease, affects the skin and peripheral nerves.
• Dermatoglyphics, the study of skin patterns, has been explored for potential links to various diseases.
• Previous research suggests possible associations between leprosy and dermatoglyphic variations.

Purpose of the Study:

• To investigate differences in fingerprint patterns between leprosy patients and healthy controls.
• To compare dermatoglyphic patterns in paucibacillary and multibacillary leprosy subtypes.
• To analyze total finger ridge count (TFRC) and individual finger ridge counts in leprosy patients.

Main Methods:

• Comparison of fingerprint patterns from 150 male leprosy patients (100 paucibacillary, 50 multibacillary) with 50 matched healthy controls.
• Analysis of dermatoglyphic patterns, including total finger ridge count (TFRC).
• Statistical comparison of pattern differences between patient groups and controls.

Main Results:

• Significant differences in fingerprint patterns were observed between multibacillary leprosy patients and controls.
• No significant dermatoglyphic differences were found between paucibacillary leprosy patients and controls.
• A notable difference in the individual finger ridge count on the first digit of the right hand was found in paucibacillary leprosy cases compared to controls.

Conclusions:

• Fingerprint pattern analysis may serve as a potential diagnostic or research tool, particularly for multibacillary leprosy.
• Dermatoglyphic variations are more pronounced in multibacillary leprosy than in paucibacillary leprosy.
• Further research is warranted to explore the specific dermatoglyphic markers associated with different leprosy types.
