The fissures of lungs are embryologically separating the bronchopulmonary segments, which later on persist in interlobar planes of fully developed lung. Fifty lungs (23 right side and 27 left side), obtained during routine dissection and preserved in formalin constituted the material for present study. In them, variations in fissures and lobes of lung were observed and compared with the previous studies. Seven right sided and 14 left sided lungs showed incomplete oblique fissure. Incomplete horizontal fissure of right lung was observed in eight lungs while it was completely missing in three specimens. A right lung with “lobe of the azygos vein” separated by a supernumerary fissure in medial surface was found. One of the right lung had both superior accessory fissure and inferior accessory fissure and four other right lungs and one left lung presented only with inferior accessory fissure. A vertical notch was found in middle lobe of one right lung. Eight left lungs exhibited with left minor fissure among them two lungs had lingula appearing as a separate lobe. Knowledge of variations in fissures and lobes is of interest to all medical professionals to exactly interpret radiographs, computed tomography scans, to diagnose, plan and modify a surgical procedure depending on the merit of the case and also in certain classical clinical cases pertaining to lung pathologies.

Dermatoglyphics, the study of epidermal ridges on palm, sole, and digits, is considered as most effective and reliable evidence of identification. The fingerprints were studied in 300 Nepalese of known blood groups of different ages and classified into primary patterns and then analyzed statistically. In both sexes, incidence of loops was highest in ABO blood group and Rh +ve blood types, followed by whorls and arches, while the incidence of whorls was highest followed by loops and arches in Rh −ve blood types. Loops were higher in all blood groups except “A –ve” and “B –ve” where whorls were predominant. The fingerprint pattern in Rh blood types of blood group “A” was statistically significant while in others it was insignificant. In middle and little finger, loops were higher whereas in ring finger whorls were higher in all blood groups. Whorls were higher in thumb and index finger except in blood group “O” where loops were predominant. This study concludes that distribution of primary pattern of fingerprint is not related to gender and blood group but is related to individual digits.

Background: The clavicle, modified long bone, presents morphological and bilateral variations. This may be due to genetic factors, hormones, or environmental and occupational influences. Anthropometric studies in clavicle of Nepalese population using radiograph has not been reported to best of our knowledge. This study, aimed to determine the sexual dimorphism and bilateral asymmetry of clavicle in Nepalese Population using Postero-Anterior Chest X Ray. Methods: Chest x-rays with normal and clearly visible both clavicles of 1260 Nepalese adults (591 male, 669 female), aged above 20 years were utilized. Inbuilt software “Computed Radiography Fuji Computer System 7” was used for measurements (in centimeter) of sternal head length, acromial end length, mid shaft diameter and length of clavicle. Demarcating point and identification point were calculated. Patients having history of clavicles fractures in the past were excluded. Results:  All the parameters in male is greater than female which is significant except Length/Mid Shaft Diameter. Similarly, all the parameters of right clavicle is significantly greater than left clavicle in both sexes except Sternal Head Length and Mid Shaft Diameter. Demarcating point calculated from length of the clavicle (right >16.17, left >16.10 for male and right <11.20, left <10.65 for female) and Mid Shaft Diameter (right >1.33, left >1.38 for male and right <0.66 and left <0.67 for female) are important parameters to determine sex.    Conclusions:The clavicle shows significant sexual dimorphism and bilateral asymmetry in Nepalese population. The result of this study is helpful to anthropologist and forensic medicine. Keywords: Anthropometry; clavicle; demarcating point; postero-Anterior chest x-rays; sexual dimorphism

Introduction: The human ear is divided into external, middle and internal ear. The auricle helps in the clinical diagnosis of congenital anomalies and syndromes. The aim of this study is to determine the mean auricular index from the right and left ears, mean measurements of left and right ear and sex-related dimensions of the ear. Methods: A descriptive cross-sectional study was conducted in medical students studying at a tertiary care hospital during the period of 1st April 2019 to 20th May 2019 after ethical clearance from the institutional review committee. Simple random sampling was done. Data were collected, entered in Statistical Package for Social Sciences version 20 and point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Results: Out of total measurements done, we found the mean auricular index was found to be for right ear 51.75±4.51mm and for left ear 54.0996±4.95682mm at 95% CI (51.75-52.37) and (53.42654.766) respectively. The mean ear length, mean ear breadth, mean lobular length and mean lobular breadth were 57.62±5.03mm, 29.72±2.79mm, 19.32±2.60mm and 20.89±3.06mm on the right side and 57.89±4.89mm, 31.21±2.95mm, 19.38±2.55mm and 21.25±2.81mm on the left side respectively. Conclusions: The mean auricular index of the external ear of medical students was within the normal range as compared to the other studies conducted.

Background: Dried human bones are essential to conduct osteology teaching learning sessions for health professional education, but its scarcity has been felt severely due to lack of simple and easy bone extraction method. Although several methods are practiced; they have their own fallacies. Hence, this study was conducted to explore simple and short method. Methods: A cross-sectional study was conducted in Nepalese Army Institute of Health Sciences (NAIHS) from April 2021 to October 2021 after obtaining ethical clearance from Institutional Review Committee, NAIHS (Reg. No- 424). Formalin fixed cadavers were used to obtain the bones by burial, maceration and chemical methods. In burial method, 600 bones were buried in the ground at 2 feet depth for six months just before monsoon. In maceration method, 200 bones were dipped in a bucket containing cow dung and water and left in the sun for 15 days. In chemical method, 50 bones were treated with washing soda for 19 hours. Remaining soft tissue was scraped, cleaned and bones were dried for 2 to 3 days. Results: Bones obtained by burial method were of good quality without any cracks but few soft tissue and mud was present which had to be cleaned manually. Bones obtained by maceration method was initially black in color. On chemical method, clean bones were obtained with few cracks. Conclusions: Among the above mentioned three methods, maceration method was less time consuming. Chemical method was faster but concentration of chemical should be proper to prevent cracks.
