Objective: The objective of the study was to describe the distribution of Keros classification among Filipinos. Methods: Study Design: Retrospective review of consecutive paranasal sinus computed tomography (PNS CT) scans. Setting and Participants: One hundred and twenty-eight consecutive PNS CT scans done at the Philippine General Hospital done from January 2006 to August 2007 were reviewed; 109 PNS CT scans were included in the study. The bilateral heights of the lateral lamellae of the cribriform plate were obtained, independently coded, and classified according to Keros classification. Results: The mean height of the lateral lamella among Filipinos was 2.21mm. One hundred sixty five cases (81.6%) were classified as Keros I. Fifty two cases (17.9%) were classified as Keros II and one (0.5%) case was classified as Keros III. There was no significant difference in the height of the lateral lamella (t-test: p=0.77, CI 95%) and the distribution of Keros classification (Fisher’s Exact test: p = 0.78) among younger (1-14 year) and older (>14 year) Filipino age groups. There was significant difference in the height (t-test: p=0.05, CI 95%) and the distribution of Keros classification (Fishers Exact Test: p=0.01) between Filipino females and males. There was no significant difference in the height of the bilateral lateral lamellae among Filipinos (paired t-test: p=0.51, CI 95%). There was no significant difference in the distribution of Keros classification (Fisher’s Exact Test: p=0.48) between the right and left lateral lamella.   Conclusions: In over 80% of the time Filipinos are classified as Keros I. Risk of inadvertent intracranial entry thru the lateral lamella among Filipinos is less compared to populations with majority of cases classified as Keros II or III.   Keywords: Keros classification, Filipino, Paranasal Sinus, PNS-CT, Ethmoid roof, Ethmoid anatomy

Background: The fallopian tubes act as conduit for spermatozoa to reach the oocyte and to convey the fertilized (egg) to enter the uterine cavity following fertilization. Problems with the fallopian tubes can lead to infertility. Detailed morphological and histological knowledge is essential for the diagnosis and management of fallopian tube disease.Objective: The purpose of the present study was to identify the inner diameter of ampulla of the fallopian tube and its changes with advancing age.Methodology: This descriptive cross-sectional study was conducted in the Department of Anatomy at Dhaka Medical College, Dhaka, Bangladesh from July 2008 to June 2009 for a period of one (01) year. This present study was performed on post mortem fallopian tubes of Bangladeshi female. Among them lowest age was 12 years and highest age was 50 years. Samples were divided into three differential age groups named asgroup A (10 to 13 years), group B (14 to 45 years), and group C (46 to 50 years). All samples were studied morphologically and histologically.Results: The mean inner diameter of the ampulla of the right and left fallopian tubes ranged from 1.99±0.08 to 3.24±0.27 mm. The difference between all the groups were statistically significant (p < 0.001).Conclusion: The mean difference of the inner diameter of the ampulla of the right and left fallopian tubesbetween groupA and groupB and groupB and groupC were statistically significant; however, there was no significant difference between right and left fallopian tube.Journal of National Institute of Neurosciences Bangladesh, 2018;4(2): 137-140

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

Background: Controversies still prevail on glomerular changes of kidney whether due to normal aging or its association with diseases Objective: The aim of the present study was to see the variation in number and size of the glomeruli of kidney with increasing age in a Bangladeshi population based on autopsy. 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 collected from 70 unclaimed dead bodies from the morgue. All the samples were divided into three age-groups: 10-19 years, 20-39 years and 40-59 years. Histological slides were prepared by using routine Harris’ Haematoxylin and Eosin (H & E) stain. The number of glomeruli was measured by point counting technique, while the size (diameter) was measured by using ocular and stage micrometer. Results: The mean ± SE number of glomeruli per sq. mm found in the right and left kidney were 8.45±0.52 and 8.67±0.80 in group 10-19 years, 9.90±0.42 and 9.92±0.47 in 20-39 years, and 8.52±0.18 and 8.55±0.16 in 40-59 years respectively. Besides, the size (mean ± SE diameter) of glomeruli was found in the right and left kidney were 43.96±3.01ìm and 143.92±2.90ìm in group 10-19 years, 153.69±5.18ìm and 153.61±5.24ìm in 20-39 years, and 140.48±0.95ìm and 140.78±0.88ìm in 40-59 years respectively. Conclusion: No difference was found in number and size of glomeruli between right and left kidney in any group. Similarly, no difference was also evident among different age groups.

Background: Among the most important predictors of functional results of treatment of syndesmotic injuries is the accurate restoration of the syndesmotic space. The purpose of this study was to investigate the reduction performance of screw fixation and suture-button techniques using images obtained from computed tomography (CT) scans. Methods: Patients at or below 65 years who were treated with screw or suture-button fixation for syndesmotic injuries accompanying ankle fractures between January 2012 and March 2015 were retrospectively reviewed in our regional trauma unit. A total of 52 patients were included in the present study. Fixation was performed with syndesmotic screws in 26 patients and suture-button fixation in 26 patients. The patients were divided into 2 groups according to the fixation methods. Postoperative CT scans were used for radiologic evaluation. Four parameters (anteroposterior reduction, rotational reduction, the cross-sectional syndesmotic area, and the distal tibiofibular volumes) were taken into consideration for the radiologic assessment. Functional evaluation of patients was done using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale at the final follow-up. The mean follow-up period was 16.7 ± 11.0 months, and the mean age was 44.1 ± 13.2. Results: There was a statistically significant decrease in the degree of fibular rotation ( P = .03) and an increase in the upper syndesmotic area ( P = .006) compared with the contralateral limb in the screw fixation group. In the suture-button fixation group, there was a statistically significant increase in the lower syndesmotic area ( P = .02) and distal tibiofibular volumes ( P = .04) compared with the contralateral limbs. The mean AOFAS scores were 88.4 ± 9.2 and 86.1 ± 14.0 in the suture-button fixation and screw fixation group, respectively. There was no statistically significant difference in the functional ankle joint scores between the groups. Conclusion: Although the functional outcomes were similar, the restoration of the fibular rotation in the treatment of syndesmotic injuries by screw fixation was troublesome and the volume of the distal tibiofibular space increased with the suture-button fixation technique. Level of Evidence: Level III, retrospective comparative study.

There is a lack of accurate three-dimensional studies to locate malar prominence for specified population, this study aims to locate the malar prominence using stable landmarks using CBCT. To derive a novel method to accurately locate the malar prominence and to assess and compare the malar prominence between males and females among Bangalore population using 3D CBCT study. All CBCT scans of study subjects belong to Bangalore population were collected from the pre-existing data available in Radiology imaging Solutions (CBCT centre), Bangalore during the period of September 10th to October 10th 2020. This is a descriptive study. A total of 42 subjects including 21 Males and 21 females were assessed using full skull CBCT scans which were converted to DICOM format and reconstructed into 3D images using NEMOCEPH 3D software. Landmarks used to locate the malar prominence were Fzs, Z, Zm and Ans. The intersection of these landmarks is considered to be as constructed maxillozygion(My). For the accuracy of the constructed Maxillozygion point (My), the distance between the actual Maxillozygion (Mzy) and constructed Maxillozygion (My) is measured and calculated between left and right halves of males and females. Three Orthogonal planes constructed were Midsagittal, Axial and Coronal Planes and the linear measurements with reference to all three reference planes in both the groups are measured. Student paired t- Test, Independent Student t Test, Mann Whitney Test. The mean distance from Mzy and my between right and left half of the face was compared using student paired t- Test. There is no significant difference (p=0.35).The mean values of the constructed anatomical landmark (maxillozygion) coordinated to three orthogonal planes between right and left sides of the face is compared using student paired T test and for both the genders (males and females) was compared using Independent Student t Test, and it is significantly higher in males as compared to females and it is statistically significant at (p=0.01). The location of malar prominence using CBCT by a novel method for Bangalore population is found which can be helpful in diagnosis and treatment planning for malar augmentation, camouflage treatment in subjects with midface deficiencies.

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.

This cross sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka from January to December 2009, to determine the proportion of cortex and medulla of the ovary in di_erent age group of Bangladeshi women. This study was based on collection of 140 ovaries of 70 unclaimed female dead bodies from the morgue of Dhaka Medical College, Dhaka. The samples were divided into three age-groups including A (10-13 years), B (14-45 years) & C (46-52 years). Histological slides were prepared by using routine haematoxylin and eosin stain. Ten best prepared histological slides from each age group were examined to determine the thickness of the cortex and medulla & proportion of the thickness of the cortex and the medulla of the ovary were expressed in percentages. The mean proportion of the cortex and the medulla of the right ovary were found 80.83±0.58% and 19.17±0.58% in group A, 86.95±1.14% and 13.05±1.14% in group B, 70.53±1.53% and 29.47±1.53% in group C respectively. The mean proportion of the cortex and the medulla of the left ovary were found 80.63±0.58% and 19.37±0.58% in group A, 86.78±1.14% and 13.22±1.14% in group B, 70.41±1.50% and 29.59±1.50% in group C respectively. The difference in mean proportion of the cortex and the medulla was not signi_cant in between the ovaries. However, the difference in mean proportion of the cortex and the medulla of the ovary between group A & group B, group A & group C and group B & group C were statistically significant.Bangladesh Med J. 2015 Jan; 44 (1): 8-10

Objective: This study was conducted to quantify the normal indices of anthropometric measures related to ophthalmology including Interpupillary distance (IPD), Inner canthal distance (ICD), Outer canthal distance (OCD) in a normal, healthy Pakistani population. Methods: This is a cross sectional study. Total 500 patients were chosen randomly but 499 were included in this study. Patients were selected randomly in an outpatient department of Jinnah Post Graduate Medical Centre Karachi, over the period of five months. IPD, ICD & OCD all measurements were taken with the help of plastic rule by only one researcher to minimize chances of error as much as possible. IPD was reconfirmed from auto refractometer while ICD and OCD readings were taken twice by occluding one eye of researcher to reduce error. Participants were divided into four categories on basis of: Age, Gender, ethnicity and geographical location. Patients were further categorized on basis of Ethnicity to Urdu Speaking, Sindhi, Punjabi, Pathan, and others. Moreover, four age groups were drawn ranging from 15-24 years, 25-44 years, 45-64 years and 65 years and greater. Results: Our study comprised a total of 499 patents of which 272(54.5%) were males, and 227(45.5%) were females. The mean age of the participants was 39.3 ± 14.5 years. The mean values for the IPD, ICD and OCD in mm were 61.8 ± 6.2, 30.9 ± 2.9 and 85.2 ± 6.6 respectively. A statistically significant difference was observed between IPD, ICD and OCD Indices among male and female study participants (p<0.001, p=0.043, p<0.001). While comparing the IPD, ICD and OCD indices amongst the different ethnic groups, we found no statistically significant difference (p=0.09. p=0.28, p=0.06). Overall, there was no correlation between the age and other variables i.e. IPD, ICD, OCD, (r = 0.07, p = 0.085), (r = 0.005, p = 0.906), (r = -0.08, p = 0.058). Conclusion: This work has recommended normative values of IPD, ICD and OCD in Pakistani population on the basis different variables including gender, age, and ethnicity.

Studies on pharmacovigilance (PV) activities in Nigeria focused on perceptions of PV among professional healthcare workers are described here. There is paucity of information on pharmacy students’ knowledge about PV activities. Hence, this study, evaluated the knowledge and perceptions of final year pharmacy students about PV activities using descriptive and inferential statistics. A cross sectional study was undertaken in three Nigerian universities with a pretested questionnaire during the period of January and February, 2016. The questionnaire included closed-ended questions on demographic variables and questions designed to achieve the objectives of the study. Data was analyzed with IBM SPSS Statistics 20 and presented in percentages, means, standard deviations and median at 50% percentile. The mean knowledge score of pharmacovigilance and adverse drug reporting for the final year students was 4.25±0.18. There were significant differences in the mean scores of knowledge domain by age groups 21-24 years 4.8±0.70, 25-30 years 6.2 ± 0.84 and >30 years 4.6±0.72 at p=0.001; gender: male 4.1±1.20 and female 4.4±0.98 at (p=0.0001) as well as the current universities attended as follows University 1 with a scrore of 5.1±1.03, University 2 had a mean score of 6.3±0.99 at p=0.0120 and University 3 with a mean score of 4.3±1.01 at p=0.012. Furthermore, significant difference exist in the mean values of pharmacovigilance knowledge between those who had taking some courses in pharmacovigilance (7.3± 0.22) and those who did not (4.7 ± 0.13) at p=0.0001. Generally, the students had inadequate knowledge of PV activities. Therefore, emphasis on relevant PV courses in their curriculum is necessary.Bangladesh Pharmaceutical Journal 20(1): 1-13, 2017
