RESUMEN
Parieto-occipital sulcus is one of the major sulcus of the cerebral hemisphere which separates the occipital lobe from the parietal lobe. Morphology of this sulcus varies with age, sex, manual skill, handedness and in many diseases. For various clinical investigations and surgery, detailed morphological knowledge of this sulcus is very much essential for the surgeons and radiologists. This study is carried out to establish a normal standard in length of the parieto-occipital sulcus in different age and sex groups of Bangladeshi people. A cross-sectional, descriptive type of study was conducted in the department of Anatomy, Mymensingh Medical College, Bangladesh from July 2016 to July 2017. About 60 specimens were collected from medico-legal cases and divided into four age groups including, Group A (20-29 years), Group B (30-39 years), Group C (40-49 years) and Group D (50 years and above). The mean length of parieto-occipital sulcus was 3.92±0.559cm to 3.29±0.434 cm in male and 3.81±0.715cm to 3.03±0.551cm in female. The difference in mean length of the parieto-occipital sulcus for both left and right hemisphere between male and female was statistically non-significant in all age groups. For statistical analysis, differences between age and sex groups were analyzed by using students unpaired 't' test. In this study, the length of the parieto-occipital sulcus showed gradual decreasing values with advancing age.

Femoral morphometric variation is a dynamic system for different region, which is influenced by geographical, physiological and environmental factors, due to the adaptation, functional and remodeling responses of bones. This descriptive cross-sectional study was conducted on 150 (64 right and 86 left) fully ossified dry human femur of Bangladeshi people to find out the variation of mid shaft antero-posterior and transverse diameter of femur. Sample was collected in the Department of Anatomy, Mymensingh Medical College (MMC), Bangladesh from January 2019 to December 2019. All samples were assessed to eliminate fractured, pathologically damaged and remodeled bones. The diameters were measured with the help of digital Vernier slide calipers. The mean±SD mid shaft antero-posterior diameter of right and left femur were 25.03±2.86 mm and 25.54±2.65mm respectively. The mean±SD transverse diameter of right and left femur was 24.24±2.43mm and 24.54±2.38mm respectively. The knowledge of variations in the parameters of dry femora will help the orthopedicians for the treatment and management of femoral shaft fracture. These data also provide information about mid shaft diameter of femur of Bangladeshi people and to compare these data to those from various other races. Thus it could contribute for the design of well-fitting prosthesis which suits the Bangladeshi population. This value may be considered while making a best-fit femoral prosthesis.

Fixed drug eruption (FDE) is a distinctive pattern of cutaneous adverse drug reaction. Characteristically the eruption recurs at the same site on re exposure to the offending agent. Aim of this study was to evaluate and identification of the various offending drugs causing FDE which may help the physician to limit the associate complication regarding the drug. This observational cross sectional study was conducted from 1st June 2021 to 31st May 2022 in the department of Dermatology & Venereology of Mymensingh Medical College Hospital after taking approval from institutional ethical committee. A detailed history with clinical evaluation were done for all patients with FDE and thereby recorded in a pre designed proforma. Analysis of data was done using Microsoft Excel 2010 Spread sheet. Out of 65 cases 36(55.38%) were male and 29(44.6%) were female. Majority of cases were found in the age group of 31 to 40 years. The most common group of drug causing FDE was NSAID (52.31%) followed by antimicrobials (44.61%) and anti epileptics (3.07%). Ibuprofen (20.0%) was the most common offending drug followed by doxycycline (18.46%), diclofenac and fluconazole (13.84%), naproxen (9.23%), ciprofloxacin (7.69%), paracetamol (6.15%), metronidazole (4.61%), carbamazepine (3.07%) and aspirin (3.07%) respectively. Extremities (43.07%) were the most frequently involved site followed by trunk (29.23%) and face (10.77%). Generalized FDE found in 16.92% cases. Although FDE are very common the offending drugs show some regional variation as a result of changing trends of pharmacotherapy.

Spleen is a haemo-lymph organ and belongs to the reticuloendothelial system of human body, develops from mesodermal proliferation between the two leaves of dorsal mesogastrium. The microscopic structure of spleen is variable depending on the developmental stage of the organ, and the age and immune status of the individual. In our country, we depend on foreign data which came from the subjects of different races and from the individuals under different geographic conditions. So the study was carried out to minimize the dependency on foreign standards and to identify the diameter of white pulp in different age and sex of the Bangladeshi individuals with a view to establish local data bank related to spleen of Bangladeshi people. This cross-sectional descriptive study was performed on 65 postmortem human spleens (34 of male and 31 of female) to find out the number and diameter of white pulp of spleen of Bangladeshi people by purposive sampling technique. And done in Autopsy laboratory of the Department of Forensic Medicine of Mymensingh Medical College, Bangladesh from 16th October 2016 to 15th January 2017. The samples were divided into three age groups including Group A (5-20 years), Group B (21-40 years) and Group C (41-60 years). Dissection was performed according to standard autopsy techniques. For statistical analysis, unpaired student 't' test was done. The mean±SD number of white pulp of male spleen was greater than female spleen in Group A, B and C but mean±SD diameter of white pulp of female spleen was found greater than male spleen in all groups. Comparison of number of white pulp between sexes showed that statistically there was no significant difference within all the age groups at p>0.05 level. No age change was evident in diameter of white pulp but in between sexes, diameter is greater in females than males. Mean difference of diameter of white pulp between sexes showed no significant difference within the age groups at p>0.05.

A cross sectional descriptive study was performed on 40 postmortem vermiform appendix (male 24 and female 16) to find out the diameter of lymphoid follicle of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique and were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). For this purpose, about 3mm long of whole thickness transverse section was taken from the middle of the vermiform appendix and thus the permanent slides were made for microscopic examination. To measure the diameter of the lymphoid follicle two measurements were taken. One was taken at the maximum diameter and another was perpendicular to it by ocular micrometer. Diameter of one largest and one smallest lymphoid follicles were measured and find out the mean diameter of lymphoid follicle between them. Diameter of lymphoid follicle = (Maximum transverse diameter + perpendicular diameter) /2. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. It was observed that diameter of lymphoid follicle of vermiform appendix gradually decreased as age advanced. The mean±SD diameter of lymphoid follicle was 580.31±37.07, 545.58±38.37, 485.68±40.20 and 428.12±68.41µm in Group A, B, C and D respectively. Statistical analysis shows that the mean differences of diameter of lymphoid follicle between A&B, C&D were statistically non significant at p= or >0.05 level, difference between Group B&C was statistically moderately significant at p<0.01 level and differences between Group A&C, B&D, A&D were statistically highly significant at p<0.001 level. Mean diameter of lymphoid follicle of vermiform appendix in male was higher (584.30±12.65µm in Group A, 549.42±38.36µm in Group B, 487.38±39.91µm in Group C, 430.68±70.30µm in Group D) than in female (576.31±53.77µm in Group A, 536.61±45.14µm in Group B, 483.14±46.68µm in Group C, 424.28±75.95µm in Group D) but mean difference between sexes in the different groups was statistically non significant at p=or >0.05 level. The present study will help to increase the information pool on the diameter of lymphoid follicle of vermiform appendix of Bangladeshi people.

This cross sectional descriptive study was performed on 70 postmortem vermiform appendices (male 34 and female 36) to find out the various positions of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique from October 2016 to March 2017. The collected samples were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). Dissection was performed according to standard autopsy technique. During postmortem examination abdominal cavity was routinely exposed by classical midline incision from xiphoid process to the symphysis pubis and a semicircular incision around the umbilicus and the flaps were reflected to give a good view of the abdominal cavity along with its contents and then the taeniae coli of the caecum were identified. The three taeniae coli of the caecum converge at the base of the appendix and become its longitudinal muscle coat. The anterior caecal taeniae coli acts as the best guide for identification of the vermiform appendix. The relation of the base of the appendix to the caecum is constant but the position of the vermiform appendix, which is variable, was studied in relation to caecum and the terminal part of the ileum. Accordingly the position of the vermiform appendix was noted either retrocaecal, pelvic, preileal or postileal, subcaecal. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. Among 70 specimens, 44(62.9%) vermiform appendices were retrocaecal in position. The next common position was pelvic which was in 22(31.4%) specimen followed by postileal in 3(4.3%) specimen and subcaecal was observed only in 1(1.4%) specimen. In this study in all age groups incidence of retrocaecal vermiform appendix was highest and it was about 67.6%, 50%, 69.2% and 72.7% in Group A, B, C, D respectively. Pelvic position was 7.1%, 46.9%, 23.1% and 27.3% in Group A, B, C, D respectively. Subcaecal vermiform appendix was absent in Group A, B and Group D. On the other hand postileal vermiform appendix was absent in Group C and Group D. The findings of this study may help the physician and the surgeons for proper diagnosis, management and treatment of disease of vermiform appendix.

A cross sectional descriptive study was performed on 70 postmortem vermiform appendix (male 34 and female 36) to find out the length of vermiform appendix of Bangladeshi people in different age and sex. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh from October 2016 to March 2017 by purposive sampling technique. The collected samples were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). Dissection was performed according to standard autopsy techniques. The vermiform appendix was collected and preserved in 10% formol-saline solution. The length of the vermiform appendix was determined by measuring the distance from its base to tip with the help of a flexible thread. Then the thread was placed on measuring scale graduated in centimeter which represents the length of vermiform appendix. The data were analyzed by using student unpaired 't' test and compared with the findings of other national and international studies and standard text books. It was observed that length of vermiform appendix gradually decreased as age advanced. The mean±SD length of vermiform appendix was 9.41±1.26cm, 8.63±1.32cm, 7.96±1.20cm and 6.81±0.75cm in Group A, B, C and D respectively. Mean length of vermiform appendix in male was 9.92±1.55cm in Group A, 9.09±1.19cm in Group B, 8.04±1.10cm in Group C, 6.88±0.86cm in Group D and in female mean length of vermiform appendix was 9.12±1.06cm in Group A, 8.31±1.34cm in Group B, 7.79±1.60cm in Group C, 6.69±0.63cm in Group D. Statistical analysis shows that the mean differences of the length of vermiform appendix between A & D, B & D were statistically highly significant. The mean difference between Group A & C was moderately significant. Between Group C & D the difference was statistically significant and between Group A & B, B & C were statistically non significant. No significance difference of length of vermiform appendix between male and female was observed. The present study will help to increase the information pool on the length of vermiform appendix of Bangladeshi people.

This cross sectional, descriptive and analytic study was conducted among 5-10 years aged 109 Bangladeshi children (70 male and 39 female) at different areas of Mymensingh district (Fulpur, Muktagacha, Fulbaria, Trisal and Haluaghat), Bangladesh from January 2016 to December 2016. Sample collection was done by nonrandom purposive sampling technique. Any kind of congenital and acquired foot deformity was excluded to construct standard measurement. The present anthropometric study was designed to construct data of 5 to 10 years aged Bangladeshi children regarding ball circumference, to measure its correlation with body weight and this attempt has been made out to grow interest among the researchers for future study and also to compare the data with the data of the people of other races. Weight of the subject was measured with the digital weighing machine and ball circumference was measured using flexible measuring tape. The children were asked to stand with weight distributed equally on both feet. The legs were perpendicular to the feet. The mean ball circumference of right side of 5, 6, 7, 8, 9 and 10 years aged male were 16.93±1.05cm, 17.00±0.72cm, 18.10±1.28cm, 18.33±.99cm, 19.37±1.12cm and 19.94±1.30cm respectively and those of female were 16.27±1.10cm, 16.85±0.59cm, 17.44±0.92cm, 18.02±0.82cm, 18.00±1.58cm and 19.23±1.40cm respectively. The mean ball circumference of left side of 5, 6, 7, 8, 9 and 10 years aged male were 16.86±1.05cm, 16.94±.70cm, 18.02±1.29cm, 18.26±.99cm, 19.27±1.12cm and 19.87±1.29cm respectively and those of female were 16.18±1.10cm, 16.77±0.62cm, 17.36±0.92cm, 17.98±0.87cm, 17.90±1.58cm and 19.13±1.40cm respectively. In this study on both sides, ball circumference showed non-significant positive correlation with body weight in 5 years old male and female, 6 years old male and female, 7 years old male and female, 8 years old female, 9 years old male and female and 10 years old male and female. In case of 8 years old male, it showed non-significant negative correlation with body weight.
