Objectives: Although the glenoid labrum is linked to glenohumeral joint stability, its anatomy remains controversial. This study aimed to investigate the shape, consistency of the glenoid labrum, and whether these and its thickness and depth are age related. Methods: A total of 140 shoulders were dissected to expose the glenoid labrum. the shape and consistency of the glenoid labrum were assessed at a gross level. Measurements were taken of the labrum depth and thickness, using callipers, in the superior, anterior, inferior and posterior regions. ANOVA and chi-square tests were conducted to determine statistical significance, which was set at p<0.05. Results: The consistency of the superior half of the labrum was rubbery in 97.9% of specimens and firm in the remaining 2.1%, whereas the entire inferior half was firm. There was a significant difference (p=0.043) in the consistency of the superior half between males and females. The superior half was triangular in 95.7% of specimens, flat in 2.1% and flat to triangular in 2.1%, whereas the shape of the inferior half was rounded in 99.3% of specimens and flat in 0.7%. The labrum was observed to be thicker in younger individuals, with the differences being significant superiorly (p=0.011), anteriorly (p=0.050), inferiorly (p=0.001) and posteriorly (p=0.047). It was also observed to be deeper in younger individuals, but only significantly so superiorly (p=0.044). Conclusion: Labrum thickness and depth significantly decreased with increasing age, suggesting that these observations could be age-related.

This study was conducted to investigate the problem of demotivation in English language learning (ELL) within the Moroccan context. To attain this objective, two instruments were adopted: a questionnaire and a writing test. The participants involved in this study were 201 baccalaureate students (second year) from six secondary schools, 84 were males and 117 were females. The data gathered was quantitatively analyzed through frequency distribution and percentages, Cross-tabulation, Chi-Square Tests, Independent Samples t-Test, in addition to the statistical significance which was set at the level of .05 (95%) for all statistical procedures. Six main findings were reported: (1) students positively perceived themselves in ELL; (2) students did not consider English language as a demotivating factor while learning it itself; (3) students were largely positive towards their teachers of English; (4) crowded classrooms were the main demotivators in learning environment among classmates, textbook of English, and classroom atmosphere; (5) generally, learning environment was the main demotivating factor in ELL; (6) as for gender, there was no significant difference between males and females in terms of the number of demotivating factors that they encountered. In the light of these findings, some pertinent implications were provided.

Background & Objectives: The current study was conducted to identify and determine the association between gender and characteristics of palatal rugae in Nepalese population.  Materials & Methods: Characteristics of palatal rugae including number, length, shape, direction and unification were analyzed in 100 maxillary dental plaster casts.  Association between palatal rugae and gender were tested using chi square analysis and statistical descriptors were identified using SPSS 10.0 keeping the level of statistical significance at p<0.05. Results: A total of 997 rugae were traced. Females were found to have more rugae than males though statistically not significant. In the present study significant difference in secondary (p=0.012), fragmentary (p=0.005), straight (p=0.001) and perpendicular directed (p<0.0001) palatal rugae were observed, which were higher among females. Forward directed followed by backward were predominantly observed and more among females. Wavy followed by curved, straight and circular rugae was the most prevalent shape.Conclusion: No two individual had similar rugae pattern. They can be used to identify people and differentiate between males and females in addition to other tools of identification and has great application in forensic science.

Hip Abduction

Context: The improvement of hip joint stability can significantly impact knee and rearfoot mechanics. Individuals with pes planus have a weak abductor hallucis (AbdH), and the tibialis anterior (TA) may activate to compensate for this. As yet, no studies have applied isometric hip abduction (IHA) for hip stability during short-foot exercise (SFE). Objective: To compare the effects of IHA on the muscle activity of the AbdH, TA, peroneus longus (PL), and gluteus medius (Gmed), as well as the medial longitudinal arch (MLA) angle during sitting and standing SFE. Design: Two-way repeated analyses of variance were used to determine the statistical significance of AbdH, TA, PL, and Gmed electromyography activity, as well as the change in MLA angle. Setting: University research laboratory. Participants: Thirty-two participants with pes planus. Intervention(s): The participants performed SFE with and without isometric hip abduction in sitting and standing positions. Main Outcome Measures: Surface electromyography was used to measure the activity of the AbdH, TA, PL, and Gmed muscles, and Image J was used to measure the MLA angle. Results: Significant interactions between exercise type and position were observed in terms of the PL muscle activity and in the change in MLA angle only, while other muscles showed significant main effects. The IHA during SFE significantly increased the AbdH muscle activity, while the TA muscle activity was significantly lower. The muscle activity of Gmed and PL was significantly increased in the standing position compared with sitting, but there was no significant difference with or without IHA. The change in the MLA angle was significantly greater in SFE with IHA in a standing position than in the other SFE conditions. Conclusions: IHA may be an effective method for reducing compensatory TA activity and increasing AbdH muscle activity during SFE for individuals with pes planus.

Objective: The aim of the study is to assess knowledge, attitude and practices of dental implants among dental interns in Saudi Arabia Materials and Methods: A self-designed, close-ended questionnaire was distributed among 205 interns chosen by stratified random sampling technique. The questionnaire consisted of 28 items pertaining to demographic characteristics, knowledge and practices of dental implants. Responses were coded and entered into spreadsheet software (Microsoft Excel 16.0.) and analyzed using Statistical Package for Social Sciences (SPSS, IBM Version 22.0) and contingency tables and chi-square test (χ2). Results: The majority of the participants were males (64.4%), between 24-26 years of age (64%) and had a GPA between 4-5 (63.4%). The majority of the participants gained knowledge of dental implants through theoretical lectures (98.5%), and most of them (80%) knew, what material, an implant was made up of. Almost all participants (91.7%) knew that dental implants had surface modifications. Most (64.4%) believed that case selection is the most important criteria for the success of dental implant therapy, and this differed significantly among participants with respect to GPA (p=0.03). Many participants (60%) believed that the most important advantage of dental implants over fixed prosthesis is that reduction of adjacent tooth is not needed, and this differed significantly between males and females (p=0.026). There was a significant difference (p<0.001) between males and females when it came to confidence in independently restoring teeth using dental implants. 63% of the participants were confident to use dental implants in their future practice. Conclusion: Knowledge of dental implants among dental interns is satisfactory, but this study reveals that participants lack practical experience and would like to acquire more clinical skills. Limitations: The response rate of participants from each university was low, which made comparisons between different universities difficult because sample size from some universities was very small, which could not produce statistically accurate results.

ABSTRACT Objective: To evaluate the effects of Dramatic Therapeutic Play (DTP) technique on the degree of anxiety in hospitalized school-age children. Method: Randomized clinical trial performed in two hospitals ofSão Paulo, between May and October 2015. The intervention consisted of the application of DTP and the outcome was evaluated through the Child Drawing: Hospital (CD: H) instrument. The Wilcoxon-Mann Whitney, Corrected t, Fisher’s exact and Chi-square tests were used in the analysis. Statistical significance was set at 5%. Results: In all, 28 children participated in the study. The majority of children (75%) had a low anxiety score, with a mean CD: H score of 73.9 and 69.4 in the intervention and control groups respectively, and with no significant difference. Conclusion: Children submitted to DTP had the same degree of anxiety as those in the control group. However, it is suggested that new studies be performed with a larger number of children in different hospitalization scenarios.

Background: Missing to detect an ischemic stroke in the emergency department leads to miss acute interventions and treatment with secondary prevention therapy. Our study examined the diagnosis of stroke in the emergency department (ED) and neurology department of an academic teaching hospital. Methods and Materials: A retrospective chart review was performed from March 2017 to March 2018. ED medical document (chart) were reviewed by a stroke neurologist to collect the clinical diagnosis and characteristics of ischemic stroke patients. For determining the cases of misdiagnosed and over diagnosed data, the administrative data codes were compared with the chart adjudicated diagnosis. The adjusted estimate of effect was estimated through testing the significant variables in a multivariable model. The comparisons were done with chi square test. Statistical significance was considered at P < 0.05. Results: Of 861 patients of the study, 54% were males and 43% were females; and the mean age of them was 66.51 ± 15.70. We find no statically significant difference between patient’s Glasgow Coma Scale (GCS) in the emergency department (12.87±3.25) and patients GCS in the neurology department (11.77±5.15). There were 18 (2.2%) overdiagnosed of ischemic stroke, 8 (0.9%) misdiagnosed of ischemic stroke and 36 (4.1%) misdiagnosed of hemorrhagic strokes in the emergency department. Conclusion: There was no significant difference between impression of stroke in the emergency department and diagnosis at the neurology department.

SUMMARYPurpose: The aim of this paper is to document the oral hygiene and nutrition habits of young people (aged 18 to 25) in Greece.Material and Methods: In a random sample of 100 people in Greece aged 18 to 25, a questionnaire including 23 questions (4 demographical and 19 other) was given. The frequency, the usual reason for visiting the dentist, the frequency of brushing, the type of toothbrush and the criteria for choosing toothbrush and toothpaste were searched. The nutrition habits were recorded as frequency in receiving sugar or no sugar meals during the day. The statistical analysis included frequencies and the use of chi-square test for interrelation with the demographical questions.Results: 72% of the sample visits the dentist at least once a year, while the reason for visiting was prevention in 69%. 85% brushes at least twice a day, and the same percentage uses medium hardness toothbrush. The choice of the toothpaste is based on flavour and fragrance in 25%. The frequency of receiving sugar meals was recorded as 45% once daily and 43% in 2 or 3 times daily (p<0.05 between smokers and non smokers). 78% of the young people receives less than 5 meals and snacks per day. There was no statistically significant difference between different available monthly budgets in the sample for the oral hygiene and nutrition habits.Conclusion: More than 1/3 of young people in Greece aged 18 to 25 visits the dentist at least once yearly for prevention and uses medium hardness toothbrush. The frequency of sugar consumption was significantly higher in smokers when compared to non smokers. Statistically significant differences were not observed between males and females except for the frequency in brushing (p<0.05). A review of the literature was performed for issues related to this project.

Background. External ear measurement is of utmost importance in reconstructive surgeries. Objectives. The present study is aimed at ascertaining sexual dimorphism in external ear anthropometry and ear lobe attachments among adults Ijaws in Bayelsa, Nigeria. Methods. A total of 112 adults within the age range of 18-50 yrs, who met the inclusion criteria, were involved in the study. Four linear dimensions of the ear, which are ear length (EL), ear width (EW), lobular length (LL) and lobular width (LW), were measured for both genders. The lobular attachment for both ears for males and females were also examined and results recorded. These data were subjected to Student t-test, Chi-square test, and Pearson’s correlation using SPSS version 20.0. Results. The mean values for EL, EW, LL, and LW for the left auricle in the males and females were 58.14±0.60, 27.41±0.37, 14.47±0.27, 13.50±0.34 and 57.90±0.16, 27.45±0.65, 15.41±0.31, 13.43±0.38 respectively. However, for the right auricle in the males and females, the values were 58.40±0.45, 28.21±0.68, 14.32±0.31, 13.04±0.32, and 56.66±1.10, 27.51±0.65, 15.58±0.29, 13.28±0.34 respectively. The left and right lobular length were the only parameters that proved statistical significance (p<0.05) in females compare to males. Pearson’s correlations between right and left sides for each of the parameters were positive and significant. Chi-square analysis revealed no significant relationship (p>0.05) between earlobe attachments and gender. Conclusions. Sexual dimorphism was thus established in the Ijaw population as regards lobular length dimensions. It is believed that the results of this study would be very useful for ear morphology and reconstructive surgeries.

The present study is designed to evaluate the effectiveness of a thigh length sequential compression device (SCD) in the prevention of deep venous thrombosis (DVT) in patients undergoing hip operations (either fracture or elective). The night before the operation phleborheography, doppler ultrasound and, when possible, 125I fibrinogen scanning were used to evaluate venous flow in the patients’ legs. The patients identified as being free of DVT complications were then fitted with the compression sleeves. Following surgery the venous evaluation tests were repeated on alternate days to determine if DVT complications had developed. Evidence of DVT formation was identified in 10 of the 52 control patients (who received leg elevation only) and in 1 of the 52 treated patients (who received the SCD plus leg elevation). The chi square statistic demonstrates a significant difference between the two groups (P<.05).Data evaluation indicates that surgical approach and patient obesity did not contribute to the risk of DVT formation. However, patients who are either over the age of 66, females, or have suffered a hip fracture appear to be at greater risk than other groups. The amount of data in this study makes it difficult to evaluate with statistical significance the additional risk produced by other factors such as heart condition, previous history of clotting problems, estrogen therapy, etc.
