Background: The structural components of the thyroid gland are very much responsive to many types of stimuli and their adaptation is evident in histological studies. The thyroid follicles change their size and shape with the physiological alterations and pathological deviations. Objective: To observe the histological changes of the thyroid gland with advancing age in Bangladeshi people. Methods: This cross-sectional study was carried out in the Department of Anatomy, Dhaka Medical College, Dhaka from January to December 2008. The present study was performed on 60 post mortem human thyroid gland (39 of male and 21 of female) collected from unclaimed dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age-groups including Group A (10 - 20 years), Group B (21 - 50 years) & Group C (> 50 years) and the glands were studied histologically including number and average diameter of the thyroid follicles, percentage proportion of the parenchyma and stroma. Results and conclusion: All the histological values of the thyroid gland studied i.e. number and average diameter of the thyroid follicles and percentage of the parenchyma, are found to increase with advancing age during the first 50 years of life and later decrease.

Context: The thyroid gland is the first endocrine organ to evolve in the vertebrates. It has right and left lobes and connected by narrow median isthmus which lies over the second, third and fourth tracheal rings. A conical pyramidal lobe often ascends towards the hyoid bone from isthmus or the adjacent part of either lobe. It measures about 1.25 cm transversely and vertically. Its size and site vary greatly. Isthmus is topographically related with some important anatomical structures. So this study was carried out to determine the incidence of presence & variation in anatomical position of isthmus of thyroid gland of Bangladeshi people of different age groups to establish a normal standard. Study type: Descriptive cross-sectional study. Place and period of study: Department of Anatomy, Mymensingh Medical College. from October’2004 to February’2005. Materials: The study was carried out on 60 cadavers of different age groups age ranging from 11 to 70 years. Thyroid glands were collected from unclaimed dead bodies autopsied in Forensic Medicine Department of Mymensingh Medical College. Methods: The collected specimens were divided into age group A (upto 18 years), group B (18 to 45 years), group C (above45 years). All specimens were examined morphologically by fine dissection method. Result: In the present study isthmus was present in 41 (68.33%) cases. In those thyroids which were devoid of isthmus, lobes were found to be merged with each other in the midline but in one case two lobes were found completely separated from each other. It was evident that the posterior relations of isthmus were widely variable. In only 18% cases it was found at its usual position- against the 2nd, 3rd and 4th tracheal rings. In the present study more frequent location of isthmus was found at 1st, 2nd, 3rd and 2nd, 3rd, 4th tracheal rings. In both cases their incidences were 18.3%. Conclusion: The present study will help to increase the information pool on the anatomy of thyroid gland of Bangladeshi people. To establish a normal standard for Bangladeshi people, further studies with large samples from different zones of the country are suggested.

Background: The pyramidal lobe is also called the 3rd lobe of the thyroid gland which ascends toward the hyroid bone from the isthmus or the adjacent part of either lobe. A fibrous or fibromascular band the levetor glandulae thyroideae occasionally extends upwards from the apex of the pyramidal lobe to the body of the hyoid bone. Any pathology of thyroid gland involves this lobe, some pathology started from here or recurrence may occur from this lobe. Anatomical knowledge about pyramidal lobe is essential for surgeons, endocrinologists, pathologists and sonologists for proper diagnosis and management of thyroid diseases. Study design: Cross sectional descriptive type of study. Place and period of study: Department of Anatomy, Sir Salimullah Medical College, Dhaka. Study period was from July 2003 to June 2004. Materials: The study was done by examining 60 post mortem human thyroid glands, age ranging from 7 to 67 years. The glands were collected from unclaimed dead bodies autopsied in the morgue of Dhaka Medical College and Sir Salimullah Medical College under the department of Forensic Medicine. Methods: The collected sample were grouped in to three age groups including group A(0-20 years), group B (21-50 years) and group C (>50 years). The presence, variation of position of the pyramidal lobe and its relation with levator glandulae thyroideae were studied. Result: The pyramidal lobe was found in 16 of 60 thyroid glands in different age groups and situated more on the left side than the right. In 9 cases, levator glandulae thyroideae were found. All extended from the apex of the pyramidal lobe to the body of the hyoid bone. Key words: Pyramidal lobe; levator glandulae thyroideae; thyroid gland.

Background: The position and size of isthmus of thyroid gland varies considerably in human with age, sex, physiologic state, race and geographical location and sometimes the isthmus may be absent. So this study was designed to find out the macroscopic differences in isthmus of thyroid gland of different age and sex groups in Bangladeshi people.Objective: To record the macroscopic characteristics of isthmus of thyroid gland with advancing age in both sexes with a view to help establishing normal standard of Bangladeshi people.Materials and Methods: This descriptive cross-sectional study was carried out on 54 autopsied human thyroid glands aged 5 to 65 years. Thyroid glands were collected from unclaimed dead bodies autopsied in the morgue of Sylhet M. A. G. Osmani Medical College, Sylhet. The collected specimens were divided into groups –– A (20 years and below), B (21 to 50 years) and C (50 years and above). All specimens were examined morphologically by careful gross dissection method.Results: The isthmus was absent in 5.56% cases. In most of the cases (35.29%) it was against the 1st–4th tracheal rings. There was significant difference in length between Group A and Group C (p<0.05) and in breadth between Group A and Group C and between Group B and Group C (p<0.05). No significant difference was found in length, breadth and thickness of isthmus of the thyroid gland between males and females.Conclusion: The presence or absence, positional change and variation in gross dimension of isthmus of thyroid gland were evident in human. The macroscopic difference was found with increasing age but not with sex.J Enam Med Col 2017; 7(1): 15-19

Context: The thyroid is a brownish red, highly vascular earliest endocrine glandular structure appears in mammal. The size of thyroid gland varies considerably with age, sex, physiologic state, race and geographical location. It is larger and heavier in females than in males, and it hypertrophies during menstruation and pregnancy. So this study is to carry out the macroscopic architecture of thyroid gland of different age groups in Bangladeshi people to establish a normal standard. Study design: Descriptive cross-sectional study. Place and period of study: Department of Anatomy, Sylhet M. A. G. Osmani Medical College, Sylhet, from July 2006 to June 2007. Materials: The study was carried out on 43 autopsied human thyroid glands aged 5 to 65 years. Thyroid glands were collected from unclaimed dead bodies autopsied in morgue of Sylhet M. A. G. Osmani Medical College, Sylhet. Methods: The collected specimens were divided into age group A (20 years and below), group B (21 to 50 years) and group C (above 50 years). All specimens were examined morphologically by fine dissection method. Result: The mean weight and volume of the thyroid gland was 13.27 ± 5.82 gm and 11.62 ± 4.76 ml respectively which are significant (p<0.01). Conclusion: From observation and results it reached conclusion that evidenced by weight and volume, the size and glandular structure gradually increase with age up to adolescence, remain stable in young and middle aged adult then slowly decline in old age. The present study will help to increase the information pool on the anatomy of thyroid gland of Bangladeshi people. To establish a normal standard for Bangladeshi people, further studies with large samples from different zones including goitre endemic zones of the country are suggested.

Pathological changes in the prostate gland occur commonly with advancing age including inflammation, atrophy, hyperplasia and carcinoma and a change in volume is also evident. Estimation of volume of prostate may be useful in a variety of clinical settings. A cross-sectional descriptive study was designed to see the changes in volume of the prostate with advancing age and done in the Department of Anatomy, Dhaka Medical College, Dhaka from August 2006 to June 2007. The study was performed on 70 post-mortem human prostates collected from the unclaimed dead bodies that were under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age groups; group A (10-20 years), group B (21-40 years) and group C (41-70 years). Volume of the sample was measured by using the ellipsoid formula. The mean ± SD volume of prostate was 7.68 ± 3.64 cm3 in group A, 10.61 ± 3.99 cm3 in group B and 15.40 ± 6.31 cm3 in group C. Mean difference in volume between group A and group C, group B and group C were statistically significant (p<0.001). Statistically significant positive correlation was found between age and volume of prostate (r = + 0.579, p < 0.001). Key Words: Prostate; volume; Bangladeshi. DOI: 10.3329/imcj.v4i2.6501Ibrahim Med.
