ObjectivesChildren with retinopathy of prematurity (ROP) often have myopia. Even without ROP, birth weight and refractive state are related immediately after birth, but this relationship is reduced with increasing age. Here, we examined whether refractive state and birth weight were associated in 40-month-old children.Methods and analysisOf 541 children aged 40 months in Tsubame City, Japan, who underwent a medical examination between April 2018 and March 2019, this cross-sectional study enrolled 411 whose birth weights were available (76% of all).We measured the non-cycloplegic refraction using a Spot Vision Screener and correlated this with birth weight. Children were divided into three groups according to normal (2500–3500 g), high (>3500 g) or low (<2500 g) birth weights, and mean differences in spherical equivalent (SE) between the groups were analysed.ResultsThe average SE for the right eye was 0.34 D (95% CI 0.28 to 0.40). Average birth weight was 3032.1 g (95% CI 2990.2 to 3073.9). Birth weight did not correlate with SE for the right eye (Pearson’s correlation, r=−0.015, p=0.765) or with the degree of anisometropia (Pearson’s correlation, r=−0.05, p=0.355). Furthermore, the mean SE showed no significant difference across the three groups of children with different birth weights (one-way analysis of variance, p=0.939).ConclusionData on refractive states and birth weight for 411 children of similar age in one Japanese city were analysed, showing that birth weight did not influence SE, J0, J45 and the absolute degree of anisometropia at about 40 months of age.

INTRODUCTION: Musculoskeletal disorders (MSDs) are one of the main reasons that force dentists to retire early from their practice. AIM: To assess the knowledge, awareness and behaviour among dental Interns in central and southern India regarding Ergonomics in DentistryMATERIALS AND METHOD: This cross-sectional study collected data using a questionnaire (pre-tested and pre-validated) amongst dental interns studying in various dental colleges in and around Central India. Participation in the study was voluntary and the questionnaire was divided into 4 sections with a total of 22 close ended questions. Data was anlayzed using SPSS version 21.0; descriptive statistics were applied followed by the unpaired samples t-test, Pearson’s correlation coefficient and multivariate logistic regression.RESULTS: The study consisted of 800 dentists, with most having fair knowledge (50.1%) and awareness (49.7%) regarding proper ergonomic posture (knowledge scores showed a significant statistical association). Most interns reported that they sometimes (41.5%) practiced dentistry ergonomically, while only 5.5% reported doing it always (significant difference, p=0.01*). A positive, linear, great strength of association (r: +0.7) and a significant relationship (p = 0.04) was found between knowledge and awareness scores using Pearson’s correlation coefficient. CONCLUSION: Dental awareness programmes are advised to educate dentists about the impending threat of MSDs if dentistry is not practiced ergonomically.

INTRODUCTION: Research has proven that music plays an important role in alleviating fear and anxiety among patients.AIM: To assess the effect of audio analgesia in pre-teen children aged 8-12 years undergoing dental restorations. MATERIALS AND METHOD: Data was collected using a pre-tested and pre-validated proforma filled by the child prior to start of the treatment by circling the number corresponding to the expected pain during the procedure [Ranged 0 (No pain) -10 (Maximum pain)]. Children who reported their expected pain above 5, were enrolled in group 1 (The ones receiving audio analgesia) while the remaining were assigned group 2 (controls). Children in group 1 were asked to put on their favourite song using noise cancellation headphones and the procedure was commenced. After completion of the treatment, the VAS scale was re-introduced and the children were asked to re-circle the actual pain experienced during the procedure. Data was analyzed using SPSS version 20.0 using the chi-squared test and Pearson’s correlation coefficient. A significant value was obtained when p was≤ 0.05. RESULTS: Of the total 80 children enrolled in the present study, there were an equal number of males and females (40 each). It was observed that 70.3% of children in group 1 had an increased pain tolerance as compared to only 37.2% of children in the control group(p=0.01). Pearson’s Correlation revealed a positive and linear association (r: +0.721) and a significant relationship (p = 0.03) between both groups. CONCLUSION: Audio analgesia has been proven to a promising alternative to distract the patient from the anxiety faced in the dental setting and is recommended for nervous and anxious patients.

ABSTRACT Objetive To determine the percentage of correctness of the Orbital Index (OI) for estimation of sex, ancestry and age in Brazilian skulls. Methods Cross-sectional study of 183 human dry skulls from the southeastern Brazil. A total of 100 skeletons were males and 83 females; of which 36 were aged up to 39 years, 60 aged between 40 and 59 years, and 87 aged 60 years or older. As for ancestry, 103 were from white, 51 mixed race, and 29 black individuals. The OI was calculate by the formula = height/width x 100. The data were submitted to Student’s t test, F (ANOVA), Tukey and Kruskal Wallis tests as well as to discriminant analysis, with a 5% significance level. Results The sample was characterized as mesoseme, with a mean age of 56.62 (±19.97) years. No significant difference was observed (p=0.511) between the OI in females (right: 86.43 ± 6.58 and left: 86.70 ± 5.93) and males (right: 85.78 ± 6.69 and left: 86.37 ± 6.20). There were no significant differences between age, ancestry and the variables analyzed (p>0.05). The right and left orbital widths were significantly dimorphic between sexes (p<0.001). The percentage of correctness of the method for estimation of sex, age and ancestry was found to be 65.6%, 43.7%, and 43.6%, respectively. Conclusions The OI is not an appropriate method for estimation of sex, ancestry and estimation of age in this Brazilian sample. The methodology should be expanded to other population groups so that it can be improved.

Background: The superficial veins of the cubital fossa are frequently variable in existence and arrangement. Many clinical procedures, such as reconstructive microsurgery and arterial bypass surgery, as well as intravenous injections or therapy, require the use of superficial veins. Aims and Objective: The aim of the study was to observe and describe the variations in anatomical distribution of the superficial veins of the cubital fossa in Nepalese pre-clinical medical students. Materials and Methods: The cross-sectional study included a total of 98 students between 18 to 24 years of age. A total of 196 anterior aspects of both arms were examined for cubital venous pattern. A tourniquet was applied at the mid-arm and drawing of the pattern of veins was made on a separate unglazed paper. The venous patterns in the cubital fossa were then categorized based on their gender. Results: Six patterns of superficial veins of the cubital fossa were observed. The commonest pattern in both genders was type I pattern. No statistical significant difference was observed between patterns of superficial veins on the right and left cubital fossa (P = 0.728 and 0.825 respectively) in both male and female subjects. Conclusion: Our research showed six venous patterns of superficial veins at the cubital fossa in Nepalese population. Understanding the common anatomy, patterns and variations of superficial vein anastomosis is imperative as this knowledge would help those needing venous access for various medical procedures.

Abstract Background: This study aimed to develop a simple and one-off olfactory screening test, the sniffing bead system, for general clinical use in older adults. Methods: In this cross-sectional study, geriatric subjects (aged > 50 years) who underwent neurocognitive and olfactory function tests were included. Overall, 137 subjects were enrolled, and the study was conducted at Chung-Ang University, Seoul, Korea. Olfactory function was measured by obtaining the scores of the sniffing bead system using 2-phenylethyl alcohol, n-butanol, and the YSK olfactory function test. Time taken for each olfactory function test was also measured. Results: The score of the 2-phenylethyl alcohol sniffing bead test was 2.58 ± 1.52, which was significantly associated with the YSK_threshold (2.41 ± 1.79) (p < 0.001, Pearson's correlation coefficient = 0.429), YSK_identification (8.93 ± 3.25) (p = 0.014, Pearson's correlation coefficient = 0.208) and YSK_threshold-discrimination-identification (17.46 ± 5.49) (p < 0.001, Pearson's correlation coefficient = 0.316) test scores. In the normal cognitive function group, YSK_threshold ( p < 0.001, Pearson's correlation coefficient = 0.479 ) , YSK_identification ( p = 0.003, Pearson's correlation coefficient = 0.316 ), and YSK_threshold-discrimination-identification (p < 0.001, Pearson's correlation coefficient = 0.429) were significantly correlated with the scores of the 2-phenylethyl alcohol sniffing bead system. In the impaired cognitive function group, the YSK_threshold (p = 0.002, Pearson's correlation coefficient = 0.415 ) and YSK_ threshold-discrimination-identification (p = 0.004, Pearson's correlation coefficient = 0.385 ) were significantly correlated with the scores of the 2-phenylethyl alcohol sniffing bead system. Time taken for the 2-phenylethyl alcohol sniffing bead system was 5.00 ± 1.51 min, which was significantly lower than that for the YSK_threshold-discrimination-identification (20.43 ± 5.29 min) (p < 0.001). The scores of the 2-phenylethyl alcohol sniffing bead system were significantly correlated with those of the n-butanol sniffing bead system (3.50 ± 1.21) (p < 0.001, Pearson's correlation coefficient = 0.315). Conclusions: This sniffing bead system was specifically designed for screening olfactory function in older adults, and it may allow for the rapid and accurate assessment of olfactory dysfunction.

(1) We aimed to compare articular eminence inclination (AEI) in normo-divergent subjects (SN^GoGn = 32° ± 5°), with different anteroposterior sagittal skeletal classes through a cone beam computed generated tomography (CBCT). (2) In this cross-sectional study, CBCT records were retrospectively analysed. From the original sample of 52 CBCT records, 33 records of normo-divergent adult subjects were selected (11 Class I, 13 Class II and 9 Class III). On mid-sagittal section of the Temporomandibular Joint (TMJ) on both sides, AEI was calculated by graphic method. (3) The Kruskal–Wallis test was used to evaluate any difference between AEI on both left and right sides in the three groups. No statistically significant difference was observed on either the right side (p = 0.174) or the left side (p = 0.624). (4) Articular eminence inclination seems to be not related with skeletal class. Given the lack of significance in the observed differences between AEI and skeletal classes, we believe that future studies should focus on assessing possible relationships between AEI and different vertical skeletal patterns.

Purpose: To investigate the effect of ocular dominance on pattern electroretinogram (PERG) recordings in the participants who have no ophthalmic diseases. Methods: One hundred and twelve eyes of 56 participants (mean age 32.96 ± 10.82 years) were included in this prospective, cross-sectional study. After detailed ophthalmological examination and determination of the ocular dominance with hole-in-a-card test, the PERG was performed to determine implicit time and amplitudes of P50 and N95. Results: There were no significant interocular differences in visual acuity, refractive error, or intraocular pressure ( p > 0.05 for all). Thirty-six (64.3%) of the participants had ocular dominance in the right eye. The dominant eyes had significantly higher P50 amplitude than in the fellow nondominant eyes (6.90 µV in dominant vs 5.87 µV in nondominant; p = 0.015; 95% confidence interval). There was no significant difference in N95 amplitude, N95/P50 ratio, and implicit times of P50 and N95 between the dominant and nondominant eyes of the participants ( p = 0.090, p = 0.124 p = 0.817, p = 0.668; respectively). Conclusion: The analysis revealed a significantly increased P50 amplitude of the PERG, which is known to be highly associated with macular function, in dominant eyes of the patients when compared to fellow nondominant eyes.

BACKGROUND The incidence of multiple pregnancies in industrialized countries due to the use of assisted reproductive techniques has increased over the past two decades. Multiple births are more dangerous than single pregnancies for mother and baby. This study evaluated the frequency of multiple pregnancies and its neonatal complications.METHODS In this cross-sectional study, we assessed all multiple neonates hospitalized in Fatemieh Hospital of Hamadan, Iran from September 2016 to September 2017 in terms of gender, gestational age, birth weight, the use of assisted reproductive techniques, delivery method, cause of hospitalization, therapeutic intervention, and hospitalization outcome.RESULTS Of 10,581 deliveries during the study period, 351 (3.3%) was multiple pregnancies and 232 neonates hospitalized. The incidence of twin, triplet, and quadruplet birth were 1.7%, 0.39%, and 0.11% respectively. In this study, 178 twin and 54 triplet and quadruplet birth were compared. The mean gestational age and mean birth weight of triplet and quadruplet were lower than that of twin births (p<0.001). A significant difference was found on the frequency of assisted reproductive techniques (p<0.001). Female sex (p=0.007), lower mean gestational age (p=0.009), lower mean birth weight (p=0.017) and need to mechanical ventilation (p<0.001) were significantly associated with early neonatal death in multiple pregnancies.CONCLUSIONS The incidence of multiple births was high in the Hamadan province, which was often followed by infertility treatment. Moreover, multiple births cause prematurity, low birth weight, respiratory distress syndrome, and increased neonatal mortality rate.
