Context: Mandible is the lower jaw bone providing attachment of muscles of mastication and facial expression and provides pathway for inferior alveolar nerve and vessels. The mandibular ramus is almost vertical in adult but more oblique in old age. The anterior part of ramus can be used as the donor site for reconstruction of small bone defects in the oral and maxillofacial region. A relatively short mandibular ramus may be an important unfavorable anatomic factor in difficult laryngoscopy. The aim of this study was to determine the morphometry of mandibular ramus from various anatomical landmarks in one hundred eighty five dry adult human mandibles. Materials and Methods: A cross-sectional, analytical type of study was conducted in the department of Anatomy, Dhaka Medical College, Dhaka from July 2010 to June 2011. Morphometry of mandibular ramus was measured with the help of digital sliding calipers. Results: The mandibular ramus was at the same distance from each landmark on both sides demonstrating symmetry. There was no significant difference in the values on the right and left sides of the mandibles. Conclusion: Anatomical knowledge of this study might be useful in certain surgical procedure.

Context: Mandible is the lower jaw bone providing attachment of muscles of mastication and facial expression and provides pathway for inferior alveolar nerve and vessels. Adequate anaesthesia is a prerequisite of most of the dental procedures. Effective pain control in dentistry may be achieved by the local anaesthetic techniques; the most common procedures which are followed by the inferior alveolar nerve block. Therefore, identification of mandibular foramen is important for dental surgeons in nerve block and surgical procedures to avoid injury to neurovascular bundle. The aim of this study was to determine the position of the mandibular foramen from various anatomical landmarks. Materials and Methods: A cross sectional analytical type of study was carried out in the department of Anatomy, Dhaka Medical College, Dhaka on one hundred and eighty five (185) dry adult human mandibles of unknown sex. Position of mandibular foramen was determined using the distance of the mandibular foramen to (a) the anterior border of the ramus (b) the posterior border of the ramus (c) the mandibular notch (d) the head of the mandible (e) the posterior edge of third molar socket and (f) the symphysis menti which were measured with the help of digital sliding calipers. Results: The mandibular foramen was at the same distance from each landmark on both sides demonstrating symmetry. There was no significant difference in the values on the right and left sides of the mandibles. Conclusion: Anatomical knowledge of this study might be useful in certain surgical procedure.

Background: The morphological knowledge of the mandibular foramen is very important during dental procedures involving lower jaw, as structures that pass through this foramen are at risk. Inferior alveolar nerve (IAN) block is the most frequently used nerve block technique in dental practice. Location of mandibular foramen is clinically important in Inferior alveolar nerve (IAN) block, dentoalveolar surgery planning, and various endodontic treatments. Present study aimed to locate the precise location of mandibular foramen in relation to the borders of the mandibular ramus, its distances from different bone landmarks on internal surface of ramus of dry mandible and incidence of occurrence of accessory mandibular foramen in local population. Material And Methods: Present study was a cross-sectional study of 50 (fty) dry adult human mandibles, obtained from the dissection room of the department of Anatomy, NMCH, Patna, Bihar. Location of MF(Mandibular foramen) from various parameters was determined with digital Vernier calipers. The presence of accessory mandibular foramen in and around mandibular foramen on the medial surface of mandibular ramus was by simple visual observation with the help of a magnifying lens and their prevalence rate was noted. All the above parameters were carefully documented and statistically analysed. Statistical analysis was done using SPSS version 23. Student's t test was used as test of signicance to compare the mean values of right and left sides and a P-value less than 0.05 was taken to be statistically signicant. Results: Total 50 dry adult human mandibles were studied. The mean distance of mandibular foramina to anterior border of ramus was 16.97 ± 2.13 (R) mm and 17.04 ± 2.72mm(L), to posterior border was (R): 13.73 ± 2.28 mm and (L): 14.16 ± 2. 05 mm, to mandibular notch was (R): 20.50 ± 2.11 mm and (L): 20.10 ± 2.82 mm and to inferior border was (R): 26.93 ± 3.09 mm and (L): 26.37 ± 4.25 mm. We noted that there was no signicant difference in the values on the right and left sides (p>0.05). All mandibles (100%) have bilateral mandibular foramen. Unilaterally Single Accessory mandibular foramen was present in 11 (22%) mandibles. Unilaterally double accessory mandibular foramen was present in 06 (12%). Bilateral double accessory mandibular foramen was noted in 02(04%) mandibles only. Bilateral single accessory mandibular foramen was noted in 04(08%) mandibles. Conclusion: Present study provides valuable information regarding distances between mandibular foramen and surgically encountered anatomical landmarks, which is very useful to dental surgeons.

Background: The superficial veins of the cubital fossa are frequently variable in existence and arrangement. Many clinical procedures, such as reconstructive microsurgery and arterial bypass surgery, as well as intravenous injections or therapy, require the use of superficial veins. Aims and Objective: The aim of the study was to observe and describe the variations in anatomical distribution of the superficial veins of the cubital fossa in Nepalese pre-clinical medical students. Materials and Methods: The cross-sectional study included a total of 98 students between 18 to 24 years of age. A total of 196 anterior aspects of both arms were examined for cubital venous pattern. A tourniquet was applied at the mid-arm and drawing of the pattern of veins was made on a separate unglazed paper. The venous patterns in the cubital fossa were then categorized based on their gender. Results: Six patterns of superficial veins of the cubital fossa were observed. The commonest pattern in both genders was type I pattern. No statistical significant difference was observed between patterns of superficial veins on the right and left cubital fossa (P = 0.728 and 0.825 respectively) in both male and female subjects. Conclusion: Our research showed six venous patterns of superficial veins at the cubital fossa in Nepalese population. Understanding the common anatomy, patterns and variations of superficial vein anastomosis is imperative as this knowledge would help those needing venous access for various medical procedures.

Context: Kidney volume is a sensitive index of kidney size for the detection of renal abnormalities. It is also excellent predictor of renal function and correlates very well with body indexes. The present study was done on cadaveric specimens to see the age related changes in the volume of the kidney in a Bangladeshi population and to compare with the previous local and foreign studies. Methods: This cross-sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from July 2008 to June 2009, based on collection of 140 post mortem human kidneys from 70 unclaimed dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. All the samples were divided into three age groups including A (10-19 years), B (20-39 years) and C (40-59 years). The length, breadth and thickness of each kidney were measured by using a slide calipers and recorded. Then the volume was determined by using prolate ellipsoid formula i.e. length × breadth × thickness × 0.52. Results: The volume of the right and left kidneys were found 54.46±4.02 cm3 and 53.15±1.98 cm3 in group A, 78.31±10.41 cm3 and 75.90±8.32 cm3 in group B, 74.47±6.22 cm3 and 73.34±6.80 cm3 in group C. No statistically significant difference was found between the right and the left kidney in any group. However, statistically significant differences were evident between A & B and A & C (P<0.001). Conclusion: No difference was found in volume between the right and the left kidney in any group. However, kidney volume was found to increase with advancing age in apparently healthy Bangladeshi people.

Background: Tendoachilles is the chief plantar flexor of the ankle joint. The present study was conducted to find out the possible variations of tendoachilles between the right and the left leg of both male and female.Materials and methods: A cross sectional observational study was conducted in the department of Anatomy, Dhaka Medical College, Dhaka, from July 2013 to June 2014. The data were collected from both the right and the left tendoachilles of 60 human cadavers taken from Anatomy Departments of different Government and Nongovernment Medical Colleges in Dhaka city. Among the 60 cadavers, 30 were male and 30 were female. After dissection, the length of tendoachilles and the breadths at different levels of tendoachilles were measured and recorded.Results: The mean length of tendoachilles was significantly greater in the right than in the left leg of both male and female. The tendoachilles was longer in male than in female in both the right and the left leg (P<0.01). There was significant positive correlation between the height of cadaver and the length of tendoachilles of both the right leg and the left leg in case of male. Positive correlation was also observed between the height of cadaver and the length of tendoachilles of both the legs in case of female, but that was not statistically significant. The mean breadths of tendoachilles were significantly greater in the right leg than in the left leg at its junction with gastrocnemius and at the level of its junction with calcaneus in both male and female and also in male than in female in both legs. Significant difference was observed between the breadth of right and left tendoachilles at the level of 4 cm above its junction with calcaneus in male but not in female (P>0.05).Conclusion: Significantly greater values were observed in the length and in most of the breadths of tendoachilles in the right leg of both sexes and in male in both legs. There was significant positive correlation between the height of cadaver and the length of tendoachilles of both legs in case of male, but, not in female.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.388-394

Purpose. This study was carried out on an Iranian population aiming to investigate mental foramen position relative to inferior border of mandible and skeletal midline and its gender and age differences on CBCT projections. Materials and Methods. A number of 180 CBCT images of patients were analyzed in different planes (tangential, cross-sectional, and axial). The distances from the superior border of mental foramen to the inferior border of mandible and from the anterior border of mental foramen to the midline were calculated. Results. The mean distance from mental foramen to the inferior border of mandible in the right side was 13.26 mm (SD ± 2.34) and in the left side was 13.37 mm (SD ± 2.19). There was a statistically significant difference between genders in terms of the distance between mental foramen and inferior border of mandible (P value = 0.000). The mean distances from mental foramen to midline were 25.86 mm (SD ± 0.27) and 25.53 mm (SD ± 0.31) in the right and left sides, respectively. Conclusions. The vertical and horizontal positions of mental foramen can be determined from stable anatomical landmarks such as mandibular inferior border and skeletal midline in both dentulous and edentulous patients. The distance from the superior border of mental foramen to the inferior border of mandible exhibited sexual dimorphism.

ABSTRACT Objective: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. Methods: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day after surgery. The Cryotherapy Injury 3 was entailed treatment with cryotherapy by immersion of the animal in recipient for 20 minutes during 1 day, then animals were euthanized at the 3rd day after surgery, and the Cryotherapy Injury 8 and the Cryotherapy Injury 15 was treated for 6 days, and euthanized at the 8th and 15th day after surgery. Functional evaluation was performed by the grasping strength of the right pelvic limb. The right tibialis anterior muscles were evaluated for mass, smaller diameter and cross-sectional area. In the Cryotherapy Injury 8 and the Cryotherapy Injury 15 groups, the hydroxyproline was dosed in the right soles. Results: In the compression there was a significant difference in the Injury Groups compared with the Control Group (p<0.05). In the smaller diameter, the compression in Control Group was higher than Injury 8 (p=0.0094), Injury 15 (p=0.002) and Cryotherapy Injury 15 (p<0.001) groups. The comparison between groups with euthanasia in the same post-operative period, a significant difference (p=0.0363) was seen in day 8th after surgery, and this result in Cryotherapy Injury Group was greater than Injury Group. In the fiber area, Control Group was also higher than the Injury 8 (p=0.0018), the Injury 15 (p<0.001) and the Cryotherapy Injury 15 (p<0.001). In hydroxyproline, no significant difference was seen between groups. Conclusion: Nerve damage resulted in decreased muscle strength and trophism, the cryotherapy delayed hypotrophy, but this effect did not persist after cessation of treatment.

Background: The liver is the organ most subjected to the development of abscesses and made up 48 % of all visceral abscesses' and 7% of all intra abdominal abscesses. Liver abscess should be suspected when there is a combination of fever, leucocytosis, constitutional symptoms, and pain in the right upper quadrant, and tenderness over the liver or right lower rib cage. The liver is affected by a number of local and disseminated infections; their frequency and types vary considerably around the world. Parasitic disorders are more prevalent in developing countries. Methods: It was a cross-sectional descriptive study. The cases were taken from the admitted patients of Medicine unit of SMCH, Chittagong. The study was conducted over a period of one year with a sample size of 50 patients and sample was taken by purposive sampling. Results: Among 50 patients 40 (80%) were diagnosed as ALA and 10 (20%) were diagnosed as PLA. ALA cases are common in 21-30 years age group & PLA cases are more common in >50 years of age group. Majority of the cases were from rural area. Common clinical features were fever, abdominal pain, nausea and tender hepatomegaly. Diarrhea was present on admission in 7 (15.9%) patients of ALA. Anaemia was common in both but polymorphonuclear leucocytosis was moderate to severe in PLA. Microscopic examination of stool samples for E. Histolytica trophozoites was positive in 3 (7.5%) cases and cysts in 4(10%) cases. Nine patients had right sided pleural effusion. Conclusions: Clinical features are common in both ALA and PLA. Liver abscesses are more common in men and more prevalent in rural areas. ALA more commonly occurs in 21-30 years age group but can occur at any age. Pyogenic abscess is more common in older age group (>50 years) and E. Coli is the commonest organism.

The height of the maxillary alveolar ridge can be measured using panoramic radiography. The decline occurred because the height of the alveolar ridge undergoes slow physiological resorption due to the absence of mechanical stimulus. The purpose of this research is to know the difference and the average height of the maxillary alveolar ridge in edentulous and dentate women using panoramic radiography. This study is an analytical method with a cross-sectional approach. A total sample of 40 women, edentulous and dentate has been measured. Measurements were made by measuring the distance between the lowest point of the infraorbital ridge and alveolar crest maxilla on the incisor point, right and left premolar, right and left molar. A statistical test is done using independent t-test. The results showed that the average value of a dentate women sample is greater than edentulous. The average value obtained by the dentate sample is greatest in incisor point by 37,57mm± 3,34mm and the smallest at the right molar point by 33,87mm ± 2,81mm. The average value obtained by the edentulous sample is greatest in incisor point by 35,30mm ± 2,79mm and the smallest at the right molar point by 31,84mm ± 3,85mm. It can be concluded that there is a significant difference in the height of the maxillary alveolar ridge on an edentulous sample and dentate, except the right molar teeth. The average height of the maxillary alveolar ridge in an edentulous sample is 33,35mm ± 3,43mm, and the dentate sample is 35,66mm ± 3,21mm.
