ABSTRACT
Background: Morphometric analysis of the foramen magnum of dry human skulls in Gujarat region was carriedout to demonstrate the anatomical variations in morphology. The measurements of the foramen magnum areclinically important because vital structures passing through it. There are certain diseases associated withcompression of structure present in foramen magnum like arnold chiari malformation (tonsillar herniation),achondroplasia, stenosis of foramen magnum, meningioma and atlanto-occipital fusion.Objectives: The aim of this study was to measure anteroposterior & transverse diameter of foramen magnum,surface area and index of foramen magnum and to observe its various shapes.Materials and methods: 326 dry skulls of adult human being were studied. Antero-posterior and TransverseDiameter were measured by using a digital vernier caliper. The surface area and foramen magnum index werecalculated. The cranial base was visually assessed for the shape of foramen magnum.Results: The mean antero-posterior and transverse diameter of the foramen magnum were 34.18 ± 2.74 mm and28.49 ± 2.13 mm respectively. The mean surface area and the foramen magnum index were 766.86 ± 104.76 mm2and 83.60 ± 6.21 mm respectively. The percentages of different shapes of foramen magnum were: Oval (42.33%),Round (32.82%), Tetragonal (8.59%), Hexagonal (7.67%), Pentagonal (4.60%), and irregular (3.99%).Conclusion: The knowledge of various dimensions & shape of the foramen magnum help to determine somemalformations like arnold chiari syndrome in which the transverse diameter is increased. The antero-posteriordiameter of foramen magnum was more than the transverse diameter and most common shape of foramenmagnum was found to be Oval.
ABSTRACT
Objective: To determine whether the Dermatoglyphics parameters in Pulmonary tuberculosis patients (sputum smear positive cases) and normal healthy controls were differ or not. Materials and Methods: In present study 100 cases (77 males and 23 females) of Pulmonary tuberculosis (sputum smear positive) in the age group of 18 to 70 were collected and studied for Dermatoglyphics parameters such as ‘ATD’ angle, total and absolute finger ridge counts. These parameters of cases were compared to those of 100 unrelated healthy subjects (controls) and analyzed for statistical significance. Results and conclusion: In present study we observed decrease ‘ATD’ angle in both hands of male and female cases as compared to controls that difference was statistically highly significant. There were no statistically significant difference observed in total finger ridge count (TFRC) and absolute finger ridge count (AFRC) of cases compared to controls. Dermatoglyphics can be used for screening tool for Pulmonary tuberculosis contacts for genetic susceptibility to disease as a cost effective, noninvasive harmless technique.
ABSTRACT
Introduction: The ATD angle and finger ridge count, are palmar dermatoglyphics features of an individual. During the first & second trimester of pregnancy epidermal growth occur in stages and result in an increase epidermal thickness. Epidermal ridges begin to appear in embryos at 10th week and are permanently established by 17th weeks. The types of pattern develop in palm & soles are genetically determined. They are of considerable clinical interest because they affected by certain anomalies of early development including genetic disease. Objective: There are certain genetic (Chromosomal), Non chromosomal & metabolic disease shows particular palmer dermatoglyphics features so in this study we were trying to find out the difference in dermatoglyphics features in leprosy patient and control group. Materials and Methods: The sample consists of 100 cases of leprosy in age group of 18-60 year from Bhavnagar district. The finger print and palm print were taken by using ink & pad method and Compared with Control group of 18-60 years. The dermatoglyphics parameter like ATD angle, TFRC & AFRC were studied and evaluated for statistical significance. Results and Conclusion: There was statistically significant difference was observed in ATD angle as compared with control. There was no statistically significant difference observed in TFRC & AFRC as compared with control. The dermatoglyphics features can be useful diagnostically to differentiate the leprosy patient and control group.
ABSTRACT
Introduction: There are three facets over superior surface of calcaneum which forms Sub talar or talocalcaneal joint: Anterior, middle, and posterior talar facet. Three types of calcaneum that have distinct talar facets Were defined as types A, B and C. Materials and methods A total of 250 calcaneum (130 right, 120 left), with unknown gender, were dried and evaluated. Results In our study type B calcaneum (68.8%) was defined as the most common type, and type A calcaneum (30.8%) was second. By using joint facet differences and bone measurement, we tried to define calcaneum bone. Discussion In many diseases of foot, such as the talocalcaneal arthritis and coalition, intra articular fractures and congenital dysmorphology, flatfoot, valgus deformities, the size and shape of the bones, the relationships of the talus and calcaneum with each other and other bones of the foot must be considered for the internal and external fixation and surgical procedures. Type B calcaneum was defined as the most common Type in Gujarat region and these results correlate with the ones which were performed on bones of American, Indian and African, Turkish race and it was uncorrelated with the results of the Researches performed in Europe.
