Background: Venous network of hand is superficially placed and is easy to trace for clinical purposes. Ce-phalic vein on lateral aspect and basilic vein on medial aspect of the hand are clinically important for inva-sive and surgical procedures. Thus the study of cephalic and basilic veins at dorsal venous arch of hand was dissected to observe for length of dorsal venous arch and the diameter and thickness of cephalic and basilic veins. Methods: This is a cross-sectional observational study conducted in 50 hands of cadavers (36 hands of male cadavers, 14 hands of female cadavers) in Department of Anatomy, Kathmandu Medical College Teaching Hospital, Duwakot. Cadavers were performed to measure the length of dorsal venous arch, diame-ter and thickness of cephalic and basilic vein on dorsum of hands. Results: The mean±s.d. length of dorsal venous arch in male cadaver (19.03±2.84 cm.) was significantly greater than in female (16.51±1.36 cm.).There was no significant difference in length of dorsal venous arch on right (18.22 ±2.47 cm.) and left side (18.42±3.05 cm.) in either sex. The mean±s.d thickness of basilic vein (0.10±0.01mm) in either sex was significantly greater than that of cephalic vein (0.09±0.01mm). Conclusions: The length of the dorsal ve-nous arch in male cadavers was found significantly greater than in female cadavers. The diameters based on external and internal circumference of basilic veins was found to be more than diameter of cephalic veins in both male and female cadavers. The thickness of basilic vein was found to be more (0.10±0.01mm) than that of cephalic vein (0.09±0.01mm) in cadaver of both sexes.
Introduction: The fragile nature of the nasal septum and other bony structures makes them prone to fragmentation and destruction. Deviated nasal septum persists in adult stage of life giving rise to anatomical, psychological and cosmetic consequences. There are many consequences of deviated nasal septum like nasal obstruction, mouth breathing, headache and asymmetry of face. The amount of airflow and resistance to it in the nasal cavity with deviated nasal septum are quite different from person to person. Our study is focused on the prevalence of deviated nasal septum. Materials and methods: This was a cross-sectional observational study conducted among 300 individuals from Nepalese preclinical students studying at Kathmandu Medical College Teaching Hospital (KMCTH). Prevalence of deviated nasal septum in males and females were determined affecting symmetry of the face. Results: The prevalence of deviated nasal septum was found to be 53% (159) of total study population. The left sided nasal septal deviation was found to be more in male 33.33% (50) than that of female 29.33% (44).The asymmetry of the face was observed in 55% (165) of total study population. However, asymmetry of face was observed more in male 58.66% (88) than in female 51.33% (77). Conclusion The deviated nasal septum and asymmetry of the face were remarkably prevalent among Nepalese preclinical students studying at Kathmandu Medical College Teaching Hospital. The prevalence of deviated nasal septum and asymmetry of face was found significantly greater in male than in female (p< 0.05).
Introduction: Dorsal venous arch of upper limb is the beginning site for cephalic and basilic veins. The superficial veins are clinically important for venipuncture, blood collection and blood donation as well as for health screening and testing, intravenous transfusion for the emergency treatment of hypovolemic shock. Veins of the upper limb are also used for total parental nutrition, therapeutic invasive procedure and blood samples. The Dorsal Venous Arch is superficially placed and can be easily made prominent by putting a tourniquet at the wrist for any such surgical and therapeutic purposes. Methods: It was a cross-sectional observational study conducted in 200 hands among 100 individuals from MBBS first and second year students studying at a Medical College. Body Mass Index (BMI) of individuals was calculated to observe the correlation between length of the dorsal venous arch and BMI. Results: The mean±s.d. length of dorsal venous arch in male on right hand (20.7±2.4 cm) was significantly greater than in female on right hand (19.4±2.1 cm).There was no significant difference in length of dorsal venous arch on left side between male (20.1±2.2 cm.) and female (19.3±1.8 cm). Conclusions: The length of the dorsal venous arch on right hand was found significantly greater in male than in female. Also the length of dorsal venous arch on right side was found to be more than on left side in both sexes. The male students are significantly older, heavier and taller than females.
There is paucity in literature describing the morphology of sub-axial vertebra of the local population. Available studies are limited to the body, intervertebral disk, spinal canal and Torg’s ratio of the cervical vertebra. Therefore, the present study aims to document various morphological parameters of sub axial vertebra. Sixty-four dry sub-axial vertebrae of the Nepalese population were studied using Vernier Calipers calibrated to 0.1 mm accuracy. Paired parameters of pedicle, lamina, uncinate process, the distance of the apex of the uncinate process to intervertebral foramen and foramen transversarium were measured. Similarly, unpaired parameters including spinous process length, vertebral foramen anteroposterior width, vertebral foramen transverse diameter and Torg’s ratio were evaluated. Except the height of left lamina of C3 to C6 vertebrae, none of the parameters showed significant side differences. Significant higher values of C7 were noted against C3-C6 on vertebral body height, vertebral body anteroposterior diameter, spinous process length and vertebral foramen anteroposterior diameter. Population data of sub-axial vertebra available in literature showed mixed results with ours. Interestingly, our observations either compared to (lamina, uncinate process, anteroposterior diameter of spinal canal and Torg’s ratio) or were larger (Pedicle and spinous process) than the Indian study with pedicle axis length being largest among all the compared studies. The information of this study may be used as a reference database for our local setting and could be of value in preoperative planning and in designing implants.
Introduction: Cardiac coronary dominance plays a significant role in different clinical conditions and diseases of the heart. As the people of developing and developed nations are having global coronary artery diseases, it is mandatory to have knowledge of coronary artery diseases including cardiac coronary dominance. The aim of this study is to find out the prevalence of the right coronary artery dominance in cadaveric human hearts in a medical college. Methods: A descriptive cross-sectional study was conducted among all 52 preserved hearts as well as the heart isolated from cadavers obtained from the teaching hospital. The study was conducted from 24th June, 2020 to 24th December, 2020 after obtaining ethical clearance from the Institutional Review Committee (Reference number: 2306202004). All cadaveric heart specimens were laelled with numbers and photographed for easy description of anatomical variation related to the coronary artery. Data were entered into Microsoft Excel 2007 and analysed using Statistical Package for the Social Sciences version 20.0. Point estimate at 90% Confidence Interval was calculated along with frequency and proportion for binary data. Results: Out of 52 undissected isolated cadaveric hearts, the right cardiac dominance was found in 42 (80.76%) (71.77-89.75 at 90% Confidence Interval). The mean diameter of the right coronary artery was found to be 4.06±0.55 mm. Conclusions: The prevalence of right cardiac dominance in isolated cadaveric hearts was similar to the studies done in a similar setting.
