Background: Tibial tubercle–trochlear groove (TT-TG) distance is often used as a measure of lateralization of the TT and is important for surgical planning. Purpose: To investigate if increased TT-TG distance measured on axial magnetic resonance images is due to lateralization of the TT or medialization of the TG. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 84 knees (28 normal [NK], 28 with trochlear dysplasia [TD], and 28 with patellar dislocation without TD [PD]) were examined. The medial border of the posterior cruciate ligament (PCL) was chosen as the central anatomic landmark. The distance from the TT to PCL (TT-PCL) was measured to examine the lateralization of the TT. The distance from the TG to the PCL (TG-PCL) was measured to examine the medialization of the TG. Between-group differences were investigated by use of 1-way analysis of variance. Results: The mean values for TT-TG distance were 8.7 ± 3.6 mm for NK, 12.1 ± 6.0 mm for PD, and 16.7 ± 4.3 mm in the TD group ( P < .01). The mean values for TT-PCL distance were 18.5 ± 3.6 mm for NK, 18.5 ± 4.5 mm for PD, and 21.2 ± 4.2 mm in the TD group ( P = .03). The mean values for TG-PCL distance were 9.6 ± 3.0 mm for NK, 7.1 ± 3.4 mm for PD, and 5.1 ± 3.3 mm in the dysplastic group ( P < .01). Conclusion: The present results indicate that increased TT-TG distance is due to medialization of the TG and not lateralization of the TT. Knees with TD had increased TT-TG distance compared with the knees of the control group and the knees with PD. The TT-PCL distance did not differ significantly between groups, whereas the TG-PCL distance declined with increased TT-TG.

The aim of our study was to evaluate the morphogenetic variability as a marker of smoking dependency in adult smokers versus controls and to investigate the presence and the degree of morphogenetic variability difference between male and female smokers versus same gender controls. The cross-sectional study evaluated 241 smokers and 185 nonsmoker individuals as controls. We analyzed 17 homozygous recessive characteristics (HRC). There was a significant difference in the individual variations of 17 HRCs between the controls and smokers (??2=61.400, p<0.001; for females ??2=79.440, p<0.001; for males ??2=84.972, p<0.001). The mean values of HRCs significantly differed between smokers and controls (MV?SEM(Controls) -4.79?0.13, MV?SEM(Smokers) -5.70?0.12; p<0.001). For males, presence of 6/17 (35.29% genetic homozygosity) HRCs (OR=6.12) was to the certain degree predictor for smoking dependency. Higher degree of genetic homozygosity, changed variability and male gender, might be some among potential numerous factors that could have impact on smoking development and dependence.

This report on overweight is based on a cross-sectional study in Skaraborg County, Sweden, in 1977. Mean values of Body Mass Index (BMI) are higher in this county than in other areas studied in Sweden and abroad. In correlation analysis the strongest association was found between overweight and hypertension. This is of particular interest since other studies have shown that Skaraborg county, has one of Sweden's highest proportions of treated hypertensives and also higher mortality during the 1970s in hypertension and obesity related diseases. The BMI varied between the municipalities of the county. Overweight was most common in the agricultural municipalities. The mean value of the BMI was higher among workers and persons with less formal education. This is contradictory to earlier Swedish studies with regard to men but not women. Physically demanding jobs accounted for more overweight individuals whereas high physical activity during leisure time was correlated with low body weight.

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

Hypochondria is a mental disorder characterized by a preoccupation with fears that a person may be ill or suffering from a serious illness, based on a misinterpretation of problems that cannot be eliminated by appropriate medical reassurance. A special type of hypochondriasis known as Medical Student Syndrome (MSS) refers to student's fears and beliefs that they are ill or may become ill with the illnesses they are learning while studying in pre-clinical and clinical subjects. A cross-sectional study was conducted during the winter semester of the 2019/2020 school year, with a sample of 90 students of the first, third, and sixth year of the Faculty of Medicine, sampled on a random basis. Subjects completed the Illness Attitude Scale (IAS). The aim of study was to investigate whether there is a difference in the incidence of hypochondrial tendencies and beliefs in the students of the Faculty of Medicine in relation to the year of study. The mean values on certain subscales were statistically significantly higher in students of third compared to students of first and sixth year of medicine. Students who have not renewed a year were found to have significantly higher average scores on the Disease Concerns and Pain Concerns subscale, as well as Disease phobia compared to those who renewed the year, while Hypochondrial beliefs were statistically significantly higher in subjects who renewed the year compared to students who had not renewed the year. The presented results support the hypothesis that health anxiety and all its components among the medical students at the preclinical level is most pronounced in the third year of study, and that it shows declining trend in the later stages of study.

ABSTRACT Aims This work was designed to assess the role of diet and dietary habits on women fertility. Materials and methods This study was carried out in seven different centers and hospitals in Baghdad in the period between January and September 2014. Participants were 400 adult women selected conveniently; their age ranged from 17 to 47 years and they were divided into two groups. Group I included 300 fertile women and group II included 100 infertile women. A specific questionnaire had been designed and used for data collection Results It was found that there was a significant difference in weight and body mass index (BMI) between the infertile group and control group. The mean of weights was 73.07 vs 69.06 kg for infertile and the control group respectively, while the mean BMI was 28.83 vs 26.70 for the infertile group and the control group respectively. Moreover, the infertile women consumed more of carbonated beverages, tea, chicken, and fish than the control group, while they consumed less milk and red meat than the control group. Also, the infertile group consumed less corn oil and olive oil than the control group (5 and 0% vs 21 and 2%) respectively, while they used to consume more solid fat and combined fat than the control group (2 and 6% vs 0 and 2.7%) respectively. Conclusion Although treatment options for infertility are available, their high cost and frequency of adverse events have motivated the identification of dietary factors related to infertility. The current study identified diet as one of the modifiable risk factors that potentially impacts fertility in the selected groups; hence, it is important to focus more on the role of diet in women fertility and increase the awareness of women to it, along with suggesting more educational programs at the primary health care level.

Abstract Background:In this study, we aimed to evaluate the sex hormonal serum level in patients with recurrent aphthous stomatitis and compare them with healthy participants.Methods:This cross-sectional study was done on patients with recurrent aphthous stomatitis who had referred to Shiraz Dental Faculty, Oral and Maxillofacial Medicine Department during 2018-2019. The non -menopause women with recurrence of at least 3 lesions per year were enrolled in this study.The mean serum level of FSH, LH, PRL (prolactin), testosterone, DHT (Dihydrotestosterone), DHEA-S (Dehydroepiandrosterone sulfate), estradiol and progesterone of 30 participants in each group of case and control were measured and compared. The data were analyzed by SPSS version 18 and independent T-test, Mann-Whitney U test, Spearman’s correlation coefficient test, Chi-square test and Fisher’s test.Results: The mean serum level of DHEA-S in patients with recurrent aphthous stomatitis (RAS) was significantly lower than the control group (p value=0.002). In addition to DHEA-S, the mean serum level of testosterone was lower in the evaluation group although this difference was not significant (p value=0.057).Considering the effect of age on the mean serum level of sex hormones, our results revealed that only DHEA-S mean serum level was decreased by increasing the age of participants in patients with RAS (p value=0.018).The number of participants with abnormal range of testosterone (p value<0.0001) and progesterone (p value=0.037) serum level was significantly more in patients with RAS. The frequency of RAS in a year did not show a significant relationship with the serum level of the evaluated hormones.Conclusion: The patients with RAS had a lower serum level of DHEA-S. The mean serum level of testosterone and progesterone was significantly abnormal in RAS patients.

Objective: To evaluate the mean values of Genial angle measured by Lateral cephalogram and Orthopantomogram. Study Design: comparative cross sectional study. Place and Duration of Study: Armed Forces Institute of Dentistry, Rawalpindi, from Aug 2018 to Feb 2019. Methodology: Patients irrespective of gender between the ages of 13-20 who reported for the treatment of class I malocclusion with complete anterior dentition were included. Orthopantomogram and lateral cephalogram were drawn by the same person. Gonial angle on orthopantomogram was measured by drawing tangents on posterior border of ramus and lower border of mandible on both halves of orthopantomogram. On lateral cephalogram the angle was measured between ramus and mandible. Gonial angle measured from lateral cephalogram and orthopantomogram were compared. T-test was applied. Results: Mean age of the individuals was 18.33 ± 3.97 years. The mean gonial angle measured on lateral cephalogram was 122.66 ± 1.64 degrees while the mean gonial angle measured on right and left side of orthopantomogram was 122.41 ± 1.56 degrees and 122.33 ± 1.55 degrees respectively. Conclusion: Orthopantomogram can also be used to measure gonial angle as accurately as a lateral cephalogram with the advantage that there are no superimpositions and both the gonial angles can be measured simultaneously on orthopantomogram.

Background: The number of prediabetic individuals is rising rapidly in Iran and other parts of the world. This complication seriously affects life quality and public health. Objectives: This study aimed to evaluate the anthropometric indices and biochemical measures among the prediabetic population. Methods: This cross-sectional study was conducted on prediabetic subjects in the Hoveyzeh population, Iran, during 2018 - 2019. A sample of 240 prediabetic individuals within the age range of 30-75 years enrolled in this study. The demographic characteristics, anthropometric measurements, and participants’ clinical parameters were checked out in this study. Moreover, this study investigated important demographic variables associated with anthropometric and clinical parameters. Results: The results showed that the mean values of fasting plasma glucose, triglyceride, and total cholesterol were 113.13 ± 6.8, 193.64 ± 115.44, and 193.64 ± 40.67 mg/dl, respectively. The mean values of systolic blood pressure and diastolic blood pressure (DBP) were 114.75 ± 15.25 and 73.25 ± 8.81 mmHg, respectively. The results showed no statistically significant difference between clinical and demographic variables except between DBP and marital status (P < 0.05). The prevalence of prediabetes in Hoveyzeh was closely associated with some demographic, anthropometric, and clinical variables. This study documented significant associations between height, hip circumference, and body mass index with both genders (P < 0.05). Furthermore, there was no statistical relationship between other demographic and anthropometric variables (P > 0.05). Conclusions: Based on the findings, abdominal obesity indicators may be related to prediabetes. Therefore, preventive strategies and suitable educational programs should be based on influential factors.

Axial Alignment

AbstractThis study aims to correlate the tibial tubercle to trochlear groove (TT-TG) distance with knee axial alignment. The hypothesis is that as internal torsion of the distal femur or external torsion of the proximal tibial increases, the TT-TG distance increases. We designed a cross-sectional study approved by our institutional ethics review board. We reviewed 32 computed tomography angiographies of patients that have nonjoint or bone-related symptoms. Distal femoral torsion, proximal tibial torsion, knee articular torsion (AT), and TT-TG distance were measured. A regression analysis between the TT-TG distance and the AT was performed. A positive correlation between the TT-TG distance and the AT was found. An increase in external torsion of the proximal tibial or an increase in internal torsion of the distal femur increases the TT-TG distance. For a correct interpretation of the TT to trochlear groove distance, we propose that the axial alignment should be included in the regular analysis of patellofemoral disease.
