ABSTRACT Introduction The objectives were to see the nasal prominence norm and the gender dimorphism in nasal prominence measured by Holdaway's soft tissue analysis. Materials and methods The sample size was 100 (50 males and 50 females). The subjects included in the study were of Saudi origin with class I skeletal and dental relationship and all teeth present. The age group of the patients was between 18 and 28 years. The radiographs were traced and analyzed by two students and cross-checked by an orthodontist. The nasal prominence was measured according to the technique described by Holdaway. Results The descriptive statistics were calculated for both male and female groups. The mean value of nasal prominence when male and female samples were combined was 14.08 mm. No statistically significant difference was found (p = 0.083) when genders were compared. The level of significance was set at p < 0.05. Conclusion No statistically significant difference was found when genders were compared. The value for males was normal while the value for females was less than Holdaway's normal. Clinical significance These values would aid in treatment planning for orthognathic surgery and orthodontic treatment. How to cite this article Kundi I.

Abstract Cephalic indices is useful for evaluating racial and gender differences. In this study, we aimed to asses Gender Dimorphism Using cephalometry in the Iranian Population. Different variables like cranial length (CL), cranial width (CW), and cranial height (CH) were measured and cranial index (CI), cranial capacity (CC), and brain weight of 400 Iranian volunteers were calculated. Data were analyzed by means of SPSS 22.0. There were significant differences in the mean value of all nasofacial parameters (P<0.05). The highest sensitivity and specificity to predict the gender dimorphism were related to FL and FW (0.990 and 0.97) and (0.970 and 0.94), respectively. Considering the differences between male and female cranial structures, can be useful in forensic medicine and designing neurosurgical and ergonomic instruments in addition, to distinguish and discover the gender of the humans related to the many years ago.

Introduction: The pituitary gland is the master gland of the body. It’s size varies with age and gender. MRI is the safest and effective diagnostic tool for pituitary gland examination. Objectives: This study was aim to determine the anteroposterior, height and transverse dimensions of normal  pituitary gland in different age groups of both sex with MRI. Methodology: It was a descriptive cross-sectional study. It consisted of 567 images of individuals (242 males and 325 females) of various age from 20 to 70 years from the Department of Radio- diagnosis, Dhulikhel Hospital. Results: The mean anteroposterior, height and transverse dimension of pituitary gland is 9.74±1.18 mm, 5.95±1.11 mm and 11.65±2.15 mm respectively in which females have higher value. Independent sample t test showed highly significant differences (p< 0.05) between the mean anteroposterior dimension in males and females. The present study showed the mean value of anteroposterior dimension is maximum at age group 50-59.  The mean value of height, transverse dimension and volume of males and females is maximum at 20-29 age group and minimum at 70-79 age group. One way ANOVA shows that there is significant difference between in height, transverse dimension and volume at different age group (p< 0.05). Conclusion: It was concluded that the height and volume of pituitary gland is maximum at second decade of life then it gradually decreases with age. The mean value of anteroposterior, height and transverse dimension showed greater value of females than males.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

ABSTRACT BACKGROUND: The bacterium Helicobacter pylori is strongly associated with the development of gastric adenocarcinoma. Currently, the prevalence in developed countries is 40%, but this value increases considerably in developing countries, which can reach rates bigger than 90%. OBJECTIVE: The objective of this study was to determine the mean and annual prevalence of Helicobacter pylori infection in patients from Itajaí during the period from July 1992 to April 2016, as well as the gender and age groups most affected. METHODS: After consent of the clinical director of the Gastroclinica Itajaí and confidentiality commitment about the research, the database of the Endoscopy Service of the clinic was evaluated. All the patients who underwent their first upper digestive endoscopy with urease test and/or histological analysis were included. The data were submitted to statistical analysis of prevalence by gender, age group and years of study, with subsequent correction through the confidence interval. RESULTS: The mean prevalence of Helicobacter pylori infection thru all years of study was 50.07%. With the calculation of the annual prevalences, it was evident the gradual reduction of infection in the population of Itajaí, that was 81.3% in 1992, declining to 33% in the year of 2016. When classifying the prevalence of infection by gender, it was higher in males (53.59%), and gender distribution by age group showed no statistically significant difference among genders between the ages of 40 and 80 years. In relation to the age group, the highest prevalence was in the group between 40 and 49 years. CONCLUSION: Although this study is retrospective and based on endoscopic database analysis, without access to clinical data of patients such as prior use of proton pump inhibitor and antibiotics to endoscopy, its results are important because they may reflect the current panorama of Helicobacter pylori infection in the city under study, where it has been presenting a gradual reduction of prevalence over the years, with current rates similar to that of developed countries (33%). Future studies are needed to confirm our data.

Aim: To evaluate the preferences of the dentists' attire among parents. Study Design: Descriptive cross-sectional study. Methodology: A questionnaire was used to obtain socio-demographic information and their preferences from Parents that accompanied their children to the Paediatric dental clinic. Information was also elicited from photographs showing male and female dentists’ with different attires and protective wears. The data was analyzed using SPSS version 22 and the level of significance was set at <0.05. Results: One hundred and fifty parents, comprising of 105(70%) females and 45(30%) males were assessed. The 40-49 year age-group were the majority [73(48.7%)], the female dentist was the preferred gender and there were statistically significant differences between the male and female subjects (p=0.047).  One hundred and forty-six (97.3%) wanted the dentists to wear name tags mostly for ease of identification 103(68.8%) and communication 20(13.3%). All parents wanted the dentist to don protective coat and gloves, while 123(82%) and 80(53.3%) parents preferred dentists' wearing facemasks and protective glasses, respectively. One hundred and twenty-eight (85.3%) preferred the white coats because it depicts purity/cleanliness (51.4%) and professionalism (45.7%). Dentists attire was important to 82% and there were statistical significant differences (p=0.01) between those with previous dental exposure and first-timers. There were statistically significant differences (p=0.03) between procedures [orthodontics and other procedures] done in the present visit and their perception of dentist attire. Conclusion: The preferences of the parents on protective wears, use of name tags and gender of the dentist show that identification, safety, empathy and rapport were desired from the dentist by the parents. Previous exposure of their children to the dental setting had an influence on the parents’ preferences.

Background: Lumbar lordosis is an essential postural element that has gained the interest of both clinicians and researchers for several years. It is the inward curvature made by the wedging of the vertebrae of the lumbar spine. Since there is paucity of data on the lumbar lordosis in the Lebanese population, most of the data used in clinical practice to classify hypo- and hyper-lordosis are based on studies from other races. Aim: To identify the normal LSA in a Lebanese population, then see if there is a difference between the races, and determine if this angle is affected by the gender or age. Methods: A retrospective study established to measure lumbar lordosis using LSA technique. Lateral supine lumbosacral radiographs of 128 Lebanese subjects, aged between 19 and 84 years, were analyzed. Statistical analysis was done using SPSS version 20.0. Results: The mean value (SD) of LSA was 38.980 ( + 9.90) with a min 15.70 and max 64.20. A significant difference was found between LSA and gender. However, there was no significant variation between this angle and age. Conclusion: The mean value of this angle 38.980 ( + 9.90) may form a reference for the Lebanese population. The study demonstrated that lumbar lordosis is affected by race and gender, with females having a greater LSA than males. Whereas, the latter wasn’t affected by age.

Background / Aim. Determining the value of Gissane?s angle (GA) plays a role in diagnosis and prognosis of heel fractures, determining treatment methods and assessing the outcome of surgical treatment. Normal values of the GA vary in relation to ethnicity, age and gender of the examined group, which indicates its anthropometric significance. The aim of this study was to determine the range of normal GA values in the population of Central Serbia. Methods. GA was determined on lateral radiography of the foot of 145 subjects, both sexes (67 women and 78 men), with subjects divided into 6 age groups. The patients included in the study did not have a calcaneus fracture. The obtained results were processed in the Graph Pad program. Results: The average value of GA in Serbia was 110.8? ? 8.1, ranging from 93? to 132.9?. The mean value of GA decreased with age, and no difference was observed between women and men, except in the youngest age group were women had higher GA values than men. Conclusion. The results of the study showed a wide range of normal GA values, as well as the existence of a difference in subjects of different age and sex.
