The presence of micronuclei in oral epithelial cells is considered a marker of genotoxicity, which can be identified using exfoliative cytology. The aim of this study was to investigate cytotoxic damage through the evaluation of micronuclei in the oral mucosa of smokers and e-cigarette users compared to nonsmokers. We obtained smears from the buccal mucosa of 68 participants divided in 3 groups (smokers, e-cigarette users and nonsmokers), which were further processed with Papanicolaou stain. The frequencies of micronuclei and micronucleated cells were recorded and statistically analyzed at a level of significance of p < 0.05. The mean micronuclei values per 1000 cells were 3.6 ± 1.08 for smokers, 3.21 ± 1.12 for e-cigarette users and 1.95 ± 1.05 for nonsmokers. The mean values of micronucleated cells per 1000 cells were 2.48 ± 0.91 for smokers, 2.39 ± 1.07 for e-cigarette users and 1.4 ± 0.68 for nonsmokers. Smokers and e-cigarette users had significantly higher values of micronuclei and micronucleated cells compared to nonsmokers, but there were no significant differences between smokers and e-cigarette users. We concluded that the micronuclei count can be used as an early indicator for alterations of oral mucosa and exfoliative cytology represents an accessible tool which could be applied for mass screening.

This cross sectional study was carried out on 60 pregnant Bangladeshi women in the department of Radiology and Imaging, BIRDEM for measurement of Pulsatility Index (PI) of umbilical artery of their fetuses by duplex colour Doppler sonography during 2nd and 3rd trimester of pregnancies. Considering total 2nd and 3rd trimesters the mean PI value of umbilical artery was 1.24 (SD±0.27). While considering the gestational in separate trimesters, study showed that the value of PI in 2nd trimester was 1.33 (SD±0.29) and in 3rd trimester PI was 1.18 (SD±0.25). Paired t test shows there was a highly significant (t=35.79, df=59, Level of significance=0.001) difference between mean values of PI in different gestational ages. It was observed that there was gradual decrease of PI value with increase of gestational age (r= -0.207) but this decrease of PI was not statistically significant (p=0.113). Regression analysis between dependent PI value and independent gestational age showed linear negative relationship but this was not statistically significant (p=0.11). This study revealed that the Pulsatility index of umbilical artery was decreased with increase of gestational age from 2nd to 3rd trimester.

Introduction: Human nose is one of the important anthropometric parameters for identification of ethnicity and sex of an individual of an unknown identity. The nasal index holds a great value in anthropological studies, because it is one of the anthropometric indices acknowledged in nasal surgery as well as management. The study aims to find the mean nasal index and the nose type of dental students of Kantipur Dental College of Nepal. Methods: This descriptive cross-sectional study was conducted among 140 dental students of age groups 17-25 years, in the Department of Anatomy, Kantipur Dental College Teaching Hospital and Research Center, Basundhara, Kathmandu. The studied population belongs to dental students of Kantipur Dental College and Research Centre. The nasal parameters including the nasal height, nasal width was measured using Digital Vernier Caliper and the nose was classified in three different types based on the value of nasal index. Results: The mean nasal index of total population was 81.34±14.88 mm with confidence interval range of 78.85 and 83.83 mm. Mesorrhine type of nose was found to be most common among the total population. Mean nasal index in male is 84.49±12.46 mm and in female is 80.66±15.32 mm. Conclusions: This study concludes that the mean values of nasal index of all the students falls under mesorrhine (medium) type of nose.

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.

ABSTRACT Objective To evaluate the indicators duration of anesthesia, operative time and time patients stay in the operating rooms of different surgical specialties at a public university hospital. Methods It was done by a descriptive cross-sectional study based on the operating room database. The following stages were measured: duration of anesthesia, procedure time and patient length of stay in the room of the various specialties. We included surgeries carried out in sequence in the same room, between 7:00 a.m. and 5 p.m., either elective or emergency. We calculated the 80th percentile of the stages, where 80% of procedures were below this value. Results The study measured 8,337 operations of 12 surgical specialties performed within one year. The overall mean duration of anesthesia of all specialties was 178.12±110.46 minutes, and the 80th percentile was 252 minutes. The mean operative time was 130.45±97.23 minutes, and the 80th percentile was 195 minutes. The mean total time of the patient in the operating room was 197.30±113.71 minutes, and the 80th percentile was 285 minutes. Thus, the variation of the overall mean compared to the 80th percentile was 41% for anesthesia, 49% for surgeries and 44% for operating room time. In average, anesthesia took up 88% of the operating room period, and surgery, 61%. Conclusion This study identified patterns in the duration of surgery stages. The mean values of the specialties can assist with operating room planning and reduce delays.

The anthropometric reference data used to examine the growth pattern of children in Spain are obtained from studies carried out several years ago. In the region of Extremadura, the tables obtained by the Faustino Obergozo Foundation, which date back to 2004, are used. The first objective of this work is to develop growth tables and graphs that accurately reflect the somatometric variables of children in Extremadura. Secondly, the averages of these variables by sex will be compared to determine if there are significant differences between them. A database provided by the General Directorate of Planning, Training, and Health and Social Quality of the Regional Government of Extremadura was used, which contains the measurements of height, weight, and body mass index (BMI) of boys and girls in Extremadura between the years 2006–2016. The database was analyzed using the Statistical Package for the Social Sciences (SPSS) version 23 and the R software version 3.5.1, considering a cross-sectional study. As a result, the tables and growth graphs of Extremadura’s population base for weight and height are presented, from birth to 10 years, as well as comparisons of the average values of the analyzed variables between boys and girls. We found that there are significant differences in the mean values, according to sex, of the height and weight. On the other hand, BMI progressed normally when comparing the results of the Extremadura population with those reflected by the World Health Organization (WHO). Differences were found when comparing the results with those obtained by the Faustino Orbegozo Foundation.

Introduction: Limits of movement in knees is one of the most common complications following trauma and surgery. With early diagnosis and appropriate treatment choices, knee replacement and performance improvement are expected in many patients. However, limits of movement in knees is unpleasant and should be corrected as soon as possible. In this study, we decided to evaluate the results of arthroscopic release in motion limits of knees. Methods: This was a descriptive cross-sectional study.14 patients who referred to the Shahid Sadoughi Hospital of Yazd from 2014 to 2016 and diagnosed with knee limitation (flexion or extension restriction of more than 10 degrees) were selected. Patients were undergone arthroscopic release and followed-up for 6 months. Lysholm knee score, degrees of flexion and extension, and patient satisfaction were evaluated. The results were analyzed by SPSS-18 and statistical tests Paired T-test as well as Spearman correlation. Results: The mean age of the patients was 28.92±10.99 years. The most common type of trauma in the patients was femoral distal fracture (46.7%). The frequency of the patients' satisfaction with arthroscopy was as followed: 50% (7 patients), had moderate satisfaction, 28.6% (4 ones), high satisfaction, and 21.4% (3 ones) had low satisfaction.The mean difference in Lysholm Knee Score, improvement in degree of extension, improvement in degree of flexion and pain score before and after arthroscopy were 26.21±14.11,64.78±26.13,3.57±2.92 and 4.13±1.65,respectively.There was a significant difference between the mean values of these factors before and after arthroscopy. Conclusion: According to the results obtained, we can conclude that arthroscopic release is an effective and low-complication method in motion limits of knees.

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
