Introduction: Cataract is a common cause of vision loss and blindness in humans. After surgical management of cataract, all efforts should be focused on reducing postoperative astigmatism thus providing an excellent vision to patients. Aim: To determine the relationship between corneal incision and refraction changes before and after phacoemulsification surgery in 300 patients undergoing cataract surgery in Khatam hospital in Mashhad, Iran from January 2017 to April 2018. Materials and methods: Three hundred patients (144 women and 156 men) with cataract undergoing phacoemulsification surgery were recruited in this cross-sectional study. Refraction, keratometry and visual acuity measurement were performed before surgery. Then, a steep-based incision in the cornea was made without stitches. A 3.2 mm corneal incision was made at two supratemporal and temporal sites. The patients were followed-up for one and six months, and one year after surgery monitoring their vision and refraction, and performing keratometric measurements. Results: The mean age of the patients was 65.7&plusmn;9.54 years (age range, 42&ndash;84 years). No major complications were observed. The greatest mean of changes in corneal power was in the supratemporal incision (1.28&plusmn;0.6). Keratometry had a significant relation with the incision (p<0.04). Conclusions: An incision made along the steepest meridian leads to flatness of this meridian, this effect being more pronounced at the supratemporal incision. A temporal incision is recommended in cases where there is little difference in the keratometry of the two axes.

The aim of this study is to evaluate the change of air pollutants in the province of Van compared to the previous year during the COVID-19 pandemic. The study is a cross-sectional study conducted in Van where is a city in eastern Turkey. PM10 and SO2 values obtained from the National Air Quality Monitoring Network website. The lockdowns imposed in the province of Van within the scope of combating COVID-19 have been recorded by examining the decisions of the Sanitary Board on the Van Governorship's official website. The mean of PM10 measurement values in the period before and after COVID-19 were 40.89±19.6 µg/m3 and 41.3±20.39 µg/m3, respectively. The mean of SO2 measurement values were 17.76±18.48 µg/m3 and 23.49±20.96 µg/m3 before and after COVID-19, respectively. When one year after and before COVID-19 was evaluated, there was no difference in PM10 values in terms of year averages, while SO2 value was found to be increased compared to the previous year. However, when analyzed by months, there were months when PM10 values were found to be increased (March, September and October) and decreased (July, August and November) compared to the previous year.

Objective Third-party payers advocate for prior authorization (PA) to reduce overutilization of health care resources. The impact of PA in elective surgery is understudied, especially in cases where evidence-based clinical practice guidelines define operative candidacy. The objective of this study is to investigate the impact of PA on the incidence of pediatric tonsillectomy. Study Design Cross-sectional study. Setting Health claims database from a third-party payer. Methods Any pediatric patient who had evaluation for tonsillectomy from 2016 to 2019 was eligible for inclusion. A time series analysis was used to evaluate the change in incidence of tonsillectomy before and after PA. Lag time from consultation to surgery before and after PA was compared with segmented regression. Results A total of 10,047 tonsillectomy claims met inclusion and exclusion criteria. Female patients made up 51% of claims, and the mean age was 7.9 years. Just 1.5% of claims were denied after PA implementation. There was no change in the incidence of tonsillectomy for all plan types ( P = .1). Increased lag time from consultation to surgery was noted immediately after PA implementation by 2.38 days (95% CI, 0.23-4.54; P = .030); otherwise, there was no significant change over time ( P = .98). Conclusion A modest number of tonsillectomy claims were denied approval after implementation of PA. The value of PA for pediatric tonsillectomy is questionable, as it did not result in decreased incidence of tonsillectomy in this cohort.

BACKGROUND Odontogenic infections are recognized as one of the most common diseases in the world. Organisms that cause dental infection and are a part of the oral normal flora include dental plaque bacteria, mucosal surface bacteria, and gingival bacteria. This study aimed to investigate the prevalence of odontogenic infections by involving the facial and cervical spaces in patients referred to Shahid Rahnemoon Hospital from 2014 to 2018. METHODS This was a descriptive cross-sectional study. The sampling method was census and 308 patients with all types of odontogenic infections associated with the involvement of the facial and cervical spaces referred to Shahid Rahnemoon Hospital from 2014 to 2018 were included in the study. Questionnaire was used for data collection. The data was entered into SPSS version 23 software and analysed using statistical tests. RESULTS The mean age of participants was 31.10 ± 14.48; the mean number of hospitalization days was 4.83 ± 2.52 days; the mean body temperature was 37.45 ± 0.54. Of the 308 patients studied, 221 (71.8 %) had no history of systemic disease. Also, 294 (5 %) had no airway involvement. The most commonly prescribed antibiotic was penicillin + metronidazole with a frequency of 54.9 %, The most common tooth that was the source of infection was mandibular tooth no. 6 with a frequency of 22.7 %, the most common type of treatment was incision + drainage + antibiotic therapy with a frequency of 44.2 %; the most common involved area was the submandibular + buccal space with a frequency of 20.1 % and the most common age range of involvement was 20 - 29 years. CONCLUSIONS In odontogenic infections, penicillin + metronidazole is the most commonly used antibiotic and buccal + submandibular space is the most common area involved.

BackgroundSharing and gifting cigarettes are common in China. These social practices promote cigarette consumption, and consequently may reduce quit rates in China. This study investigated sharing and gifting cigarettes, and the relationship of observing pictorial health warnings to attitudes towards sharing and gifting cigarettes in China.MethodsWe conducted an online nationwide cross-sectional study of 9818 adults in China. Experiences of sharing and gifting cigarettes, and attitudes towards sharing and gifting cigarettes before and after viewing text and pictorial health warnings on the packages were assessed, and compared between smokers and non-smokers.ResultsMost current smokers reported experiences of sharing (97%) and gifting (around 90%) cigarettes. Less than half of non-smokers reported sharing cigarettes and receiving gifted cigarettes, but over half (61.4%) gave cigarettes as a gift to others. More than half of non-smokers but less than 10% of smokers disagreed with sharing and gifting cigarettes. After observing both text and pictorial health warnings on the packages, disagreement with sharing and gifting cigarettes increased by more than 10 percentage points among both smokers and non-smokers.ConclusionHaving pictorial health warnings on cigarette packages may reduce sharing and gifting cigarettes in China.

Background: Applying peripheral venous lactate instead of arterial lactate in clinical practice is questionable because of deviation between both values. We aimed to find the relationship between the arterial lactate and the peripheral venous lactate before reasoned that the venous lactate could be used in substitution to the arterial lactate in sepsis. Methods: We conducted a prospective, cross-sectional study at a university hospital. The patients with sepsis in ICU who required lactate level monitoring were enrolled in this research. The correlation and agreement between arterial lactate (A-LACT) and peripheral venous lactate (V-LACT) were the primary outcomes. Results: A total of 63 paired samples were collected. The A-LACT and V-LACT were strongly correlated ( r = .934, P < .0001, r2 = .873). The regression equation was A-LACT = (0.934 × V-LACT) − 0.236. The mean difference between V-LACT and A-LACT was 0.66 ± 1.53 mmol/L. The 95% limits of agreement were between −3.66 and 2.33 mmol/L. The V-LACT ≥ 4 mmol/L can predict A-LACT level ≥ 4 mmol/L with 87.5% sensitivity and 91.5% specificity, and the area under receiver operating characteristic curve was 0.948. Conclusion: The present study demonstrated a strong correlation between A-LACT and V-LACT, but an agreement between both parameters was poor. We suggest not to use the V-LACT in substitution to the A-LACT in sepsis regarding the absolute value and clearance rate, but the V-LACT ≥ 4.5 mmol/L may be used for predicting the A-LACT ≥ 4 mmol/L.

Background: The period of adolescence, beginning with the onset of puberty, is a crucial transition into adulthood. There is a substantial lacuna in the knowledge, belief and practice about menstruation. This study addresses the gap in knowledge, belief and practice regarding menstruation among adolescent girls. Methods: A community based cross sectional study was conducted over a period of one year, in an urban area of Belagavi among 625 adolescent girls in the age group of 16–19 years. Data was collected by house to house visit using a predesigned, pretested questionnaire. Results: The mean age (±SD) at menarche was found to be 12.8±1.73 years. Our study showed that as the knowledge increased, there was increase in the use of sanitary pad (p<0.001) and increase in the number of girls practicing cleaning of external genitalia during menstruation (p<0.01). However, it was found that 276 (50.5%) and 175 (37.7%) of the girls did not use sanitary pads and practice cleaning of external genitalia during menstruation even after having correct knowledge showing a gap in knowledge and practice. Similarly, among the 494 girls who knew that menstruation is a natural process, 93 (18.8%) girls wrongly believed she shouldn’t sleep in the same place as usual, 124 (25.1%) said she shouldn’t enter the kitchen, 186 (37.7%) believed that certain foods should be avoided and only 37 (7.5%) rightly believed that girls could go to place of worship during menstruation showing a gap in knowledge and belief. Conclusions: The study reported a gap in knowledge, belief and practice among adolescent girls. To bridge this gap causes have to be identified and addressed.

Objective: To investigate the adaptation of pregnant women to the recommended weight gain range according to body mass index (BMI) and to determine the factors affecting them. Methods: This cross-sectional study was performed in a university hospital’s obstetrics and gynecology unit (tertiary center) in Turkey. This study was conducted between March 2018 and August 2018 (6 months) in pregnant women. Pregnant women with chronic disease and receiving treatment during antenatal follow-up, with twin pregnancy, with a fetus with a congenital abnormality, and nutritional disturbance were excluded from the study. Eight hundred twelve pregnant women with normal antenatal follow-up and who volunteered to participate were included in the study. Results: The mean age of the participants was 27.66±5.05 years. The mean weight and BMI before pregnancy were near standard in all participants. The group with the highest rate of recommended weight gain according to BMI before pregnancy was the group with low weight pregnant women. The ideal weight gain rate in all groups was 32%. Conclusions: The groups with overweight and obese pregnant women according to BMI before pregnancy had the highest rates of weight gain, above the recommended limits. BMI before pregnancy directly affects weight gain during pregnancy and the importance of pre-pregnancy counseling and weight loss is emphasized once again. doi: https://doi.org/10.12669/pjms.35.5.133 How to cite this:Ozdilek R, Aba YA, Aksoy SD, Sik BA, Akpak YK.

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.
