ABSTRACT
Background and Objectives: The study of friction ridge patterns of fingertip is known as dermatoglyphics. Although human beings have been using fingerprints as a means of identification for a long time, in this study an effort has been made to study a fingerprint pattern examination of right hand thumb in relation to ABO Rh blood group, so that one can get an idea about the expected blood group from the study of fingerprint pattern and vice versa.Material and Methods: A plain thumb print was taken by applying ink to the tip of right hand thumb and place in the thumb directly on paper with a gen tle pressure and the rolled fingerprint was taken by rolling the thumb on paper from outward to inward in such a way as to obtain an impression of whole tip. The blood group was determined and recorded along with other details of the study subjects after taking inform consent. Data were entered in excel and analyzed.Results: It was observed that percentage of Loops were highest in AB blood group (76.92%) and O blood group with (71.05%) common in A and B blood group with 57.14%. Also, percentage of Whorls in A blood group was highest (42.86%) as compared to lowest in AB blood group (23.08%), in blood group B and O the distribution of whorls pattern are 39.28% and 28.95% respectively. Similarly, percentage of Arch was least in B blood group (3.84%).Conclusion: This study showed that there is an association between ridges of fingertip and different blood group.
ABSTRACT
Background and Objectives: Bone marrow specimen is considered as superior to the blood in the laboratory diagnosis of Kala-azar. The main objective of this study is to compare these two methods of diagnosis and determine the usefulness of the diagnostic techniques.Material and Methods: This prospective cross sectional study was conducted at Janakpur Zonal Hospital, Janakpur which was aimed to determine the usefulness of the bone marrow specimen and blood specimen in the laboratory diagnosis of Kala-azar. Bone marrow aspirate and venous blood was collected aseptically from the cases were processed simultaneously. The results of these two cultures were compared. Results: Total 60 cases of Kala-azar were included in the study of which 32 were male and 28 were female. Amastigote form of Leishmania donovani were detected in 56 (93.33%) samples with high titre of parasitemiae and 119 (18%) in the blood sample with low parasitemiae. Sensitivity and Specificity of the test was calculated of the bone marrow sample test have more sensitivity (98%) and specificity (100%) over the sensitivity (90%) and specificity (96%) of blood smear test.Conclusion: Bone marrow specimens were found to be more useful than the blood sample in the laboratory diagnosis of Kala-azar.
