ABSTRACT
Aim: The aim was to study theanalytical pattern in dermatoglyphics. Materials and Methods: The study was conducted in Skin Opd, Sree Balaji Medical College and Hospital, Chennai, TamilNadu, India. A total of 100 participants with different hand dermatitis pattern were included in the study. All patients were subjected to: 1. Complete history, 2.Dermatological examination, 3.Finger print pattern of all the patients, 4.Informed consent. Results:This hospital-based study involved 100 patients with Psoriasis (47) Eczema (23) Dermatophytosis (12), Syphilis (3), Drug reaction (5) Palmar keratoderma. (10), the most common being psoriasis and eczema. In psoriasis patients, whorl pattern was the commonest (48.29%), followed by 31.43% loop, 21.43% arch and 2.86% composite pattern. In eczema patients, loop and whorl pattern was found in (44.74%) followed by 34.23% loop, 22.43% arch and 1.86% composite pattern.Conclusion: The palmar pattern intensities were increased in both sexes, while the digital pattern intensities were increased in males and decreased in females. TFRC was increased in males and decreased in female patients. In both cases and controls, TFRC was more in males than females.A-b count showed a significant reduction in both sexes
ABSTRACT
Background: Breast cancer is very common among females these days, it’s occurrence has a strong genetic basiswhich has been already established. Palmar patterns also develop under genetic control during early developmentalmost at the same period when the mammary buds develop in intrauterine life. And they do not get alteredsignificantly after that, and thus remains almost constant during rest of the life. So these patterns may beassessed as a non-invasive anatomical marker to find the risk of developing breast cancer later in life.Methodology: In this study assessment of the palmar patterns of both hands of 109 female breast cancerpatients were taken and compared with the patterns of 109 age matched normal healthy females. The Patternswere obtained by Ink method in an A4 size white paper. Palmar ridge count (a-b ridge count), palmar angles ( atdangle and adt angle) of both the groups was measured and analysed.Results: On statistical analysis it was observed that mean a-b ridge count of right and left hands of cases weresignificantly lower when compared with the mean a-b ridge count of right and left hands of the normal healthyfemales respectively in Madhya Pradesh.Conclusion: The palmar ridge counts are significantly associated with breast cancer and in a highly populatedcountry like India with limited medical resources, it may be employed as an inexpensive and effective tool forscreening the high-risk population for breast cancer
ABSTRACT
An investigation of palmar patterns on 900 cases Han nationality of China wasmade.The main purpose of this paper is to provide the normal values of Chinese dermatoglyphics and human genetics.The main characters of palmar patterns of Han nationality are as follows:mainline A:type Ⅰ 7.89%,type Ⅲ 91%,type Ⅴ 1.11%;main line B:type Ⅴ 80.72%,type Ⅶ 16.78%,type Ⅸ0.67%,type Ⅺ0.06%,type O(absent)0.11%,typeⅢ 1.67%;main line C:type Ⅴ 38.78%,type Ⅶ 32.67%,type Ⅸ 16.06%,typeⅪ0.44%,type O(absent)12.06%;main line D:type Ⅶ and type Ⅸ all 40.61%,type Ⅺ 18.39%,type O(absent)0.39%.The average value of AD main line formula is 6.50?1.61(SD).There are sig-nificant difference between sexes and two hands(R.L.)(P0.05).The frequency of complicatedpalmar creases is 5.22%.The rate of symmetrical main lines between two hands is34.89%.The main type of A.B.C.D main line is 3.5′.5″.7(18.11%).
