A Study of Correlation between Dermatoglyphic Angle and Blood Pressure.

To resolve the biomedical problems, palmar dermatoglyphics has been used as a method. For the screening of hypertension palmar prints can be used. We wanted to determine the correlation between dermatoglyphic angle and blood pressure.METHODSThis is a cross sectional study. Palmar prints of right and left hands were taken with the help of inkpad. Blood pressure was also measured and ATD angle of both the hands were measured with the help of goniometer in 200 females and 200 male subjects of North India. Percentages, Pearson’s chi-square test, Student independent t test, one-way ANOVA were used. A p value < 0.05 was considered statistically significant. Statistical analysis was conducted using SPSS version 20.RESULTSHypertension I and II were recorded for 7.0 % (6.0% of males and 6.0 % of females) and 2.3 % subjects (3.0% of males and 1.5 % females). Overall 28.3% of subjects had prehypertension. A statistically significant difference was observed in the value of left hand ATD angle for the comparison of hypertensive and non-hypertensive subjects.CONCLUSIONSDermatoglyphics can be used as a tool for the prediction of various diseases with a genetic link. Several studies nowadays show association of dermatoglyphic angle with hypertension.

The Study On Correlation Of Dermatoglyphics And Schizophrenia

Background: Dermatoglyphics is the study of quantitative and qualitative patterns of ridges in palms and soles.It is being investigated in diseases having genetic basis. The recent evidence from adoption studies has provideda basis for the genetic contributions in schizophrenia. The present conducted to study the finger and palmardermatoglyphic patterns in schizophrenics and to compare dermatoglyphic configurations of schizophrenicswith the normal population.Materials and Methods: The ink and pad method was followed to take finger and the palm prints. The palmarprints of 50 schizophrenic patients and 50 normal individuals of both the sexes were collected for the study.Results: There is statistically significant decrease in frequency of arches in schizophrenics when compared tocontrols, whereas frequency distribution of radial loops, ulnar loops and whorls are not significant. Increase inI4 interdigital pattern is statistically significant in schizophrenics when compared to controls. There is increasein the mean values of total finger ridge count in male, female and combined series of male and femaleschizophrenics and decrease in absolute finger ridge count in male and combined series of male and femaleschizophrenics, while there is decrease in female schizophrenics, when compared to controls. Atd angle isdecreased in both the hands of male schizophrenics and right hand of female schizophrenics as compared tocontrols, whereas it is equal in the left hand of schizophrenics and controls. There is increase in the mean ridgecount in III, IV and V digits in the right hand of male schizophrenics.Conclusion: There are significant differences in the schizophrenics in various dermatoglyphic features, whencompared to controls. Hence it is possible to identify the ‘at risk’ population with the help of dermatoglyphics.

Study Of Palmar Patterns In Carcinoma Breast Patients Of Central India

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

Use of palmar dermatoglyphics in rheumatoid arthritis – A case-control study

Background: The susceptibility and severity of Rheumatoid arthritis are determined by both genetic and environmental factors. Dermatoglyphic patterns of individuals which are formed early in the fetal life are also determined by both genetic and environmental factors. Since both are genetically acquired and environmentally modified, it has been shown that there are particular dermatoglyphic patterns associated with Rheumatoid arthritis. If it is so, dermatoglyphics can serve as an additional tool in the early diagnosis and management of such a disabling disease like rheumatoid arthritis. Although there are some studies which mentioned dermatoglyphic pattern variation in the disease, the results are contradicting. Therefore, the present study was undertaken to find out a possible correlation of some quantitative and qualitative dermatoglyphic variables with Rheumatoid Arthritis. Aim of the study: To study the dermatoglyphic patterns in patients with Rheumatoid Arthritis and control population and to study the correlation between dermatoglyphic patterns and Rheumatoid Arthritis. Materials and methods: We studied 60 patients with Rheumatoid arthritis and 60 controls. All were subjected to detailed medical history and clinical examination. Both quantitative (finger ridge count and pattern intensity) and qualitative (fingerprint pattern) dermatoglyphic parameters were studied and the same were compared with age, sex and disease matched controls. Results: Out of the total 60 cases 12(20%) were male and 48(80%) were females. Of the total 60 controls, 12(20%) were males and 48(80%) were females. Analysis of the qualitative parameters revealed: Significant increase in the number of whorls in both the hands of female patients cases compared to the controls (p-value for right hand 0.001, p-value for left hand 0.004). The decrease in the number of radial loops in both the hands of male and female patients and the decrease was more in the left hand in males and right hand in females (p-value male left hand 0.002, female right hand Saritha K. Narayanan, Christopher C. Pais, Pradeep Kumar Shenoy. Use of palmar dermatoglyphics in rheumatoid arthritis - A case-control study. IAIM, 2017; 4(12): 70-76. Page 71 0.003). Decrease in the number of arches in the left hand of female patients compared to the controls (p-0.10). Analysis of the quantitative parameters showed: A statistically significant increase in the finger ridge count of individual hand and the total finger ridge count in both male and female patients compared to the controls (p-value males: right hand 0.003, left hand 0.004, right plus left hand 0.002; p-value females right hand.0000, left hand 0.000, right plus left hand 0.000). A statistically significant increase in the pattern intensity of fingers in female patients compared to the controls (p-value: right hand 0.006, left hand 0.001, right plus left hand 0.000). Conclusion: The findings of this work demonstrate the association between some of the qualitative and quantitative parameters of dermatoglyphics and Rheumatoid arthritis suggesting that dermatoglyphics can represent an anatomical, non-invasive, inexpensive tool for screening high-risk population and thus facilitate early detection and management.

An anthropometric comparison of current anthropometric test devices (atds) with Malaysian adults

Anthropometric Test Devices (ATDs) of different nominal percentile values have long been used as human surrogates in automotive crash testing. The Hybrid III family, which is one of the widely used ATDs in frontal crash test, was designed based on the anthropometry dimensions of US adults. Thus, this paper aims to assess the anthropometric differences between Malaysian adults and Hybrid III dummies in terms of 5th percentile (small female), 50th percentile (midsize male) and 95th percentile (large male). A series of anthropometric parameters of Malaysian adults was obtained from a database of 1321 subjects with 708 males and 613 females. The results revealed that the current midsize male population differs from the ATD’s statures and body weights by about 35 and 40 percentile points, respectively. This demonstrates that the current ATDs are not truly representative of the current Malaysian adults, which may potentially lead to different injury responses in road traffic crashes. Thus, car manufacturers may as well consider this discrepancy issue in developing their future models especially with regards to safety.

Study of palmar patterns in diabetic patients.

Nowadays study of dermatoglyphics has a great importance in judicial and criminal researches. Similarly its study is related to some genetic diseases has an immense applications. Diabetes Mellitus is the silent killer of mankind and public health problem. Therefore investigators are looking for new methods for its early diagnosis and treatment. Dermatoglyphics is a growing discipline and its ease and ready applicability render it as a useful tool to the clinician. Dermatoglyphics may be effectively employed as a screening procedure in future and may help in the early detection of cases of diabetes mellitus. Methods: The present study is undertaken with an aim to evaluate the dermatoglyphic features in diabetic patients. The study consists of 150 diabetic patients and 150 normal healthy individuals as controls. They were 75 males and 75 females in each group. Dermatoglyphic prints were taken by “Ink method” described by Cummins and Midlo and further subjected to statistical analysis to find the variations in the dermatoglyphic features among diabetic patients and control groups. Results: Mean value of a-b ridge count is neither increased nor decreased in diabetic patients (P = 0.852). Mean value of atd angle is slightly decreased in diabetic patients (P = 0.2332). The frequency of t and t' are increased (P = 0.8462, P = 0.6681) and the frequency of t" is decreased (P = 0.757) in diabetic patients but they are not statistically significant. Conclusion: From the present study, it appears that there do exists a variation in the dermatoglyphic patterns in diabetic patients with an advantage of being simple and economical ‘ink’ method. As the specific features of dermatoglyphic patterns are present in diabetic patients, it can be used for mass screening program to segregate the predicted diabetic patients.

A study of dermatoglyphics in club foot.

Background: Development of dermatoglyphics pattern is under genetic control and it is established that aetiology of club foot is partly environmental and partly genetic. So study of dermatoglyphics pattern in club foot patient may become a diagnostic tool to know the development & inheritance of this clinical disorder. Methods: A total of 42 male child aged b/w 1-8 year were included, for obtaining the palmar and finger tip print standard ink method suggested by Kilgariff was used, and each palmar and finger print were examined for important parameters like loops, whorls, arches, a-t-d angle, a-b ridge count and TFRC count. Then results were tabulated and analysed statistically. Results: Frequency of whorls increase in both hands significantly, frequency of arches and ulnar loops decrease significantly, frequency of radial loops increase in right hand and decrease in left hand but difference was not significant. TFRC count was reduced significantly and no significant difference was found in a-t-d angle and a-b ridge count. Conclusion: Dermatoglyphics is a genetically determined reliable marker for detecting the incidence of club foot. Merely by identifying the dermatoglyphics pattern of couples with family history of club foot may be at risk of having their offspring affected, and they can be diagnosed early and preventive measures can be taken.

Influencing Anthropometric Values to Atd Angles on Palm Prints in European American / 체질인류학회지

American population consists of people of various race and ethnic group. Palm prints are different from each individual, ethnic group and race. The aim of this study is to investigate influencing anthropometric values to atd angles formed by triradii of palm prints in European American and develop a regression equation that can predict atd angle. This study was done on 208 European American (males: 102 individuals, females: 106 individuals). Data were collected by measuring atd angles using a protractor, distance from triradii a to d, length from triradius t to the distal wrist crease (DWC), palm breadth at metacarpals and palm length perpendicular using digital callipers. The data were analyzed by descriptive statistics, the frequency, independent sample t-test, paired t-test, Pearson correlation analysis, stepwise regression using SPSS win 18.0. This study showed that atd angles of males (38.6degrees) are significantly smaller than those of females (40.4degrees). Influencing anthropometric values to atd angles in males were distance from triradii a to d, the ratio of the length from triradius t to the DWC to palm length, palm length. Influencing anthropometric values to atd angles in females were the ratio of the length from triradius t to the DWC to palm length, the ratio of the distance from triradii a to d to palm breadth, and the ratio of palm breadth to palm length. In addition to, the regression equation predicted atd angle of males was 26.150+(0.741xdistance from triradii a to d)+(52.856xthe ratio of the length from triradius t to the DWC to palm length)-(0.332xpalm length), on the other hand, that of females was -42.935+(51.657xthe ratio of the length from triradius t to the DWC to palm length)+(63.314xthe ratio of the distance from triradii a to d to palm breadth)+(42.764xthe ratio of palm breadth to palm length). The results of this study suggest that there were differences in influencing anthropometric values to atd angles between males and females in European American. Especially, the ratio of the length from triradius t to DWC to palm length was a very significantly influencing anthropometric value to atd angles to all of males and females.

Relations of Atd Angles and Anthropometric Values of Palms according to Sex Distinction / 체질인류학회지

The palm prints are unique in each individual and permanent for a lifetime. The atd angle of palm is formed by triradii of palm prints. The aim of this study is to identify the reasons why males have smaller atd angles, even with larger palms than females have. This study was done on 379 individuals (males : 174 individuals, females : 205 individuals). Data were collected by measuring atd angles using a protractor, distance from triradii a to d, length from triradii t to the distal palmar crease (DPC), palm breadth at metacarpals and palm length perpendicular using digital callipers. The data were analyzed through the frequency, independent sample t-test, paired t-test, Pearson correlation analysis using SPSS win 14.0. This study showed that atd angles of 39.2 degrees in males are significantly smaller than those of females (40.5 degrees). Males' were wider than females' in palm breadth, palm length and distance from triradii a to d, however, there was no sexual difference in the length from triradii t to the DPC. In addition, the ratio of palm breadth to palm length was higher in males than in females, however, the ratio of the length from triradii t to the DPC to palm length, and the ratio of the distance from triradii a to d to palm breadth of males were lower than those of females. Especially, atd angles in males and females were more correlative with the ratio of the length from triradii t to the DPC to palm length. The results of this study suggest that the differences in the atd angles between males and females arise from the ratio of length from triradii t to the DPC to palm length and the ratio of distance from triradii a to d to palm breadth. In both of the cases, males exhibited lower ratios than females. Especially, the ratio of the length from triradii t to DPC to palm length affected more to the atd angle than any other ratios.

La Amazonia colombiana es una reserva natural que debe conservarse inalterada, y la materia orgánica es un componente importante del suelo ya que es fuente de nutrientes para la planta. La humina del suelo ha sido poco tenida en cuenta en la sostenibilidad de este ecosistema, a pesar de que desempeña un papel fundamental en la dinámica del suelo, por lo tanto requiere ser estudiada. Los objetivos fueron: evaluar las condiciones experimentales para la extracción y el fraccionamiento de la humina de los horizontes A y BA de un oxisol del Amazonas, en cuanto a la relación sueloextractante, número de extracciones y caracterización de las fracciones obtenidas mediante análisis elemental de C, H y N; relación E4/E6 y análisis térmico diferencial (ATD). Como condiciones óptimas de extracción se encontraron: una relación suelo/extractante 1:40 en la fracción del suelo menor de 50 μm; un tiempo de agitación de una hora, con 4 extracciones sucesivas para el suelo del horizonte A, y una sola para el BA debido al menor contenido de materia orgánica. Se encontraron porcentajes de nitrógeno y un grado de aromaticidad más bajos que los de losácidos húmicos. Sin embargo, al comparar las diferentes fracciones de humina, la humina de insolubilización extraíble y la unida a hierro mostraron mayor grado de aromaticidad y de condensación que la de insolubilización no extraíble. En cuanto al análisis térmico diferencial (ATD) no se presentaron diferencias apreciables, todas las fracciones fueron más estables que los ácidos húmicos, con una zona relativamente plana entre 490 y 600 °C.

The colombian Amazonia is a natural reserve that needs to be conserved without change and organic matter is an important component of the soil for supplying nutrients to plants. The soil humin has been very little taken in to account in this ecosystem, however the humin role is considered to be very important in the soil dynamics, for this reason needs to be evaluated. The objective of this work, is considered the evaluation of the experimental conditions for the extraction and the fractionation of the humin of the A and BA horizons of an Oxisol of the Amazonia zone. This is related to the relation soil-extractant, number of extractions and the characterization of the fractions obtained by means of elemental analysis of C, H and N; E4/E6 relation and thermal differential analysis (TDA). It was found that the optimal conditions of extraction the relation soil-extractant 1:40 in the smaller soil fraction of 50 μm, the shaking time was one hour, with 4 successive extractions for the soil of the horizon A and a single one for the BA horizon, due to the high decrease on the of organic matter content. They were found lower nitrogen percentage and degree of aromaticity, with respect to humic acids. Nevertheless, when comparing the different fractions from humin, the insolubilization extractable humin and the humin bound to iron, showed greater degree of aromaticity and condensation that the insolubilization nonextractable humin. Respect to the thermal differential analysis (TDA), appreciable differences did not appear, all the fractions were more stable than humic acids, with a flat band between 490 °C and 600°C.

A new post removal technique using ATD tugging device / 대한치과보존학회지

It is common for clinicians to encounter endodontically treated teeth that contain posts within their roots. If endodontic treatment is failed, these posts must be removed to facilitate successful nonsurgical retreatment. There have been many techniques such as ultrasonic instrument, Ruddle post removal system, Eggler post remover and Masserann kit developed to facilitate removal of posts from the root canal space. But these methods may be disadvantageous because long length of time required for post removal and fracture of post or teeth. In now days new post removal technique using ATD automatic bridge remover was introduced. Advantages of this method are simple and short time consuming compare to others. This article served as a successful case report of post removal using ATD automatic bridge remover.
