Background: The human foetal suprarenal gland is structurally variant from its adult counterpart. The most distinctive features of human foetal suprarenal gland and histologically unique foetal zone, was described first by Elliott and Armour in 1911. After the first trimester, the centrally located foetal zone accounts for most of the foetal adrenal mass. The outer zone of the foetal suprarenal gland is called the “definitive zone or neo cortex”; this zone likely gives rise to the adult adrenal glomerulosa. A third zone called “transitional zone”, lies just between the neocortex and foetal zone and is believed to develop into the zona fasciculata. Aims and Objectives: The current study was designed to study the histogenesis of suprarenal glands at different gestational age groups. Materials and Methods: Twenty-eight formalin preserved dead embryos and foetuses of both sexes, were obtained from the Govt. Maternity Hospital & S.V.Medical College, Tirupati, Andhra Pradesh, India. Specimens were grouped according to their gestational age groups (A,B,C,D) A= 0-12 weeks, B= 13-24 weeks, C= 25-36 weeks and D= more than 36 weeks of gestation. Specimens from group A were subjected to serial section as this group consists of embryos, and other groups were sectioned coronal and subjected to routine histological processing for H&E staining. Sections were observed for cellular details under light microscopy with 10X and 40X magnifications, and the same were photographed by microphotography. Results: Based upon the gestational age groups, histogenesis of the suprarenal gland was observed and correlated with the available literature, and the detailed results, discussion will be dealt at the time of discussion. Conclusions: Histological observation of the all the specimens observed in the present study are in agreement with those reported in the literature except that they appeared earlier in the present study than that reported in the literature. Capsule of suprarenal gland appeared at 12 weeks, sympatho-chromaffin bundles appeared before 6 weeks and zonation of cortex was observed at 8 weeks in the present study when compared to the time of appearance reported in the literature as 14 weeks, after 6 weeks and after 12 weeks respectively in the literature.

Suprarenal Glands

Background: Fetal suprarenal gland consists of three zones. They are the outer definitive zone or neocortex (DZ) that forms adult Zona Glomerulosa (ZG), the centrally located fetal zone and a third transitional zone (TZ) the future adult Zona Fasciculata (ZF) which lies just between the neocortex and fetal zone (FZ). The inner ZF that consists of large eosinophilic cells, and the outer definitive zone (DZ) consists of small, densely packed basophilic cells. As early as in 6th week of gestational Age, pheochromoblasts derived from the neural crest migrate through the fetal cortex to form the medulla at a later stage of development. The medulla unrecognizable as a distinct structure in the suprarenal gland throughout most of the gestation, except for small clusters or nests of chromaffin cells scattered throughout the body of the cortex. Aims and Objective: The study was designed and aimed to understand the early developmental histology of suprarenal gland. Materials and Methods: Study conducted at the Department of Anatomy, SV Medical College, Tirupati, Andhra Pradesh, India. The study was carried out by processing representative samples of fetal suprarenal tissues of 13 weeks, 17 weeks, 24 weeks, 25 weeks and 38 weeks gestational age. While processing, we observed the standard dissection procedure and histopathological tissue processing for the human samples. Results: Peripheral narrower and darker definitive zone or true cortex and an inner wider and lighter fetal zone was observed at 13, 17, 24 weeks with 10x objective. The demarcation between cortex and medulla could be seen clearly at 24 weeks. At 25 weeks capsule is very thick and vascular. A well-differentiated gland tissue with clear demarcation of cortex and medulla and a large central vein was observed. At 38 weeks degeneration of fetal zone with a thick-walled central vein was observed at lower magnification (10x objective) Conclusion: Observations on prenatal microscopic structure and gestational age-related changes in suprarenal glands form the basis for understanding structural changes and a foetal database for the local population.

The purpose of the present study was to examine the profile of selected proinflammatory cytokines in maternal serum of first-trimester pregnancies complicated by threatened abortion (TACP) and its relevance to obstetric outcome. Serum levels of Th1-type cytokines interleukin-1β(IL-1β), tumor necrosis factor alpha (TNF-alpha), and Th2-type cytokine interleukin 6 (IL-6) were measured, by ELISA, in 22 women with TACP and adverse outcome at admission (group A) and compared with the corresponding levels of 31 gestational age-matched women with TACP and successful outcome at admission (group B1) and discharge (group B2) and 22 gestational age-matched women with first-trimester uncomplicated pregnancy (group C) who served as controls. Mann-Whitney U or Wilcoxon test was applied as appropriate to compare differences between groups. IL-1βand TNF-alpha were detected with significantly higher levels in group A, compared to all other groups. On the contrary, IL-6 levels were detected with no significant difference among all the other groups studied. It is concluded that in first-trimester TACP with adverse outcome, a distinct immune response, as reflected by elevated maternal IL-1β, TNF-alpha, and unaltered IL-6 levels, is relevant to a negative obstetric outcome.

Objective: To find out the frequency of subclinical hypothyroidism (SCH) in our pregnant population during 1st Trimester and the mean TSH level in first trimester of pregnancy. Study Design: Cross Sectional Descriptive study. Setting: Dow University Hospital and Dr Ruth KM Pfau CHK. Period: June 2015 to May 2016. Material & Methods: All Pregnant women with <14 weeks gestation were screened for Serum TSH level. Data were recorded after informed consent and institutional ethical approval. Variables recorded were age, parity, gestational age and serum TSH level. Data were analyzed on SPSS version 16. Mean and SD were calculated for quantitative variables ie. Age, parity, gestational age, serum TSH level and serum free T4 level. Mean TSH level according to age group, parity and gestational age groups were determined by applying ANOVA test. Correlation of Serum TSH level with the maternal age, parity and gestational age groups were also assessed by Pearson Correlation test. Significant P-value was taken as <0.05. Results: The frequency of SCH found was 19.35% by taking cut off limit of <2.5 IU/L and 3.55% by taking cut off limit of <4.5 IU/L among total of 310 pregnant women. Mean TSH level was 1.84±1.36 IU/L. The mean maternal age was 27.22 ± 4.43 yrs. while median parity was 1. Mean gestational age of these patients were 9.41 ± 2.748 weeks and out of these 160 (51.61%) were between 4-9 weeks and 150(48.38%) between 10-14 weeks. Majority (74%) of these women belonged to lower middle socioeconomic class. Mean TSH level coorelation between different age groups, parity groups and gestational age groups were found to be insignificant. Conclusion: The prevalence of SCH is not so high and mean TSH level in our population was 1.84 IU/L. But to establish reference range for Pakistani population, further studies in population of different backgrounds and geographical distribution needs to be evaluated.

Risk Of Preeclampsia

SummaryWe recruited 111 patients who were considered to be at significantly increased risk of preeclampsia on the basis of previous obstetric history or preexisting medical disorders. All patients were treated with low dose aspirin (75 mg/day) from the first occasion the patient attended the antenatal clinic, regardless of gestational age. If the maternal mean platelet volume (MPV) increased significantly (by >0.8 fl) from the baseline, antiplatelet treatment was increased. Five pregnancies were lost during the second trimester and 106 of the treated patients had live infants. The incidence of neonatal death (3/106 infants) was much lower than in the previous pregnancies in these patients (32/134 infants). Patients who were treated from the first trimester of pregnancy (group A, 89 patients) did substantially better than those treated from the second trimester (group B, 17 patients) as assessed by the incidence of pre-eclampsia or intrauterine growth restriction (IUGR), gestational age and birthweight at delivery. These data suggest that longitudinal monitoring of the MPV may identify the women who could benefit from increased antiplatelet treatment, and that antiplatelet treatment may be more effective when initiated in the first trimester rather than later in pregnancy.

Background: Medical method of abortion is a safe, effective and affordable method for first trimester termination. However, nausea, vomiting, diarhoea, excess bleeding and incomplete abortion are known side effects. The aim of study was to compare the success rate of abortions in both groups, to compare the induction-abortion interval in both groups and to study the side effects of the drugs.Methods: This study was conducted in department of obstetrics and gynecology, NIMS Medical College, Jaipur, India during June 2017-August 2017. Total hundred cases were taken and divided into two groups. Group A was gestational age upto 49 days, Group B was gestational age 50-63 days. Both groups were given tab. mifepristone 200mg. followed by 48 hrs. by 4 tablets of tab misoprostol.Results: The results of the given regimen were highly successful and complete abortion was achieved in 96% and 94% in group A and group B respectively. The difference between two groups was statistically not significant (p value =0.64). Failure rates were seen in only 4% of group A and 6% of group B. Pain abdomen was seen in 16% of group A and 38% of group B patients. The difference between both groups was statistically significant (p value=0.02). Nausea was seen in 10% of group A and 30% of group B patients. The difference between both groups is statistically significant(p value=0.018).Conclusions: First trimester pregnancy can be successfully terminated with combination of mifepristone and misoprostol upto 63 days (9 weeks) of pregnancy.

Progression Of Atherosclerosis

SummaryBlood coagulation in a strain of rabbits designated as Watanabe heritable hyperlipidemic (WHHL) rabbits was examined. The activities of vitamin K-dependent clotting factors, contact factors and clotting factor VIII (F VIII) and the fibrinogen level were significantly higher in WHHL rabbits than in normolipidemic rabbits (all age groups). Values for vitamin Independent clotting factor were already higher at 2 months of age. Contact factors and fibrinogen levels increased age after 5 to 8 months. F VIII increased between 5 and 8 months and then decreased. At 2 months of age, WHHL rabbits were divided into two groups. Group A was fed standard rabbit chow and group B standard rabbit chow containing 1% probucol. Probucol prevented the progression of atherosclerosis in group B in the absence of a significant reduction in plasma cholesterol level. F VIII and fibrinogen levels were statistically decreased in all rabbits at all ages in group B (P<0.05). These differences in clotting factors between the two groups were most obvious at 8 months (P<0.02).We conclude that vitamin K-dependent clotting factors may increase with hyperlipemia and that increases in F VIII and fibrinogen may be closely related to the progression of throm- boatherosclerosis.

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.

Connective Tissue Sheath

Deep cervical fascia forms a connective tissue sheath around the thyroid gland. Delicate trabeculae and septa penetrate the gland indistinctly dividing the gland into lobes and lobules which in turn composed of follicles.1,2,3 These follicles are structural units of thyroid gland which varies greatly in size and shape.4 The number of follicles varies in different age groups. The study was carried out to see the percentage of area occupied by follicles in the stained section of thyroid glands in different age groups. The collected samples were grouped as A (3.5 – 20yrs), B (21- 40yrs) & C (41 – 78yrs). Percentage of area occupied by follicles was (58.55±10.72) in group A, (63.79±12.35) in group B + (63.39±8.29) in group C.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13981 Update Dent.
