ABSTRACT Objective: Growth prediction plays a significant role in accurate diagnosis and treatment planning of orthodontics patients. It was hypothesized that the unique pattern of pneumatization of the frontal sinus as a component of craniofacial structure would influence the skeletal growth pattern and may be used as a growth predictor. Materials and Methods: A total of 144 subjects (78 females and 66 males) with a mean age of 19.26 ± 4.66 years were included in this retrospective study. Posterior-anterior and lateral cephalograms (LCs) were used to measure the frontal sinus dimensions. The skeletal growth pattern and relations of craniofacial structures were analyzed on LC using variables for sagittal and vertical analyses. Correlation between the frontal sinus dimensions and cephalometric indices was assessed by the Pearson's correlation coefficient. Results: The SN-FH and SNA angles had significant associations with frontal sinus dimensions in all enrolled subjects (P < 0.05). In males, the SN-FH, sum of posterior angles, Pal-SN, and Jarabak index were significantly associated with the size of frontal sinus (P < 0.05). In females, the associations of SN-FH and gonial angles with frontal sinus dimensions were significant (P < 0.05). Conclusion: The results show that larger size of frontal sinus was associated with reduced inclination of the anterior cranial base, increased anterior facial height (in males), and increased gonial angle (in females) in the study population.

Background and Objectives: The purpose of the present cross-sectional study was to determine the effects of enlarged adenoids on the growth pattern of maxilla and mandible and to evaluate the relationship between airway size and lip strain. Methods: Pre-treatment lateral cephalograms of twenty-five children (10 boys, 15 girls) were taken. The children selected for the study were in the age group of 5 – 13 years (mean age of 10 years) during the year 2008- 11. All the tracings were made on 75µm lacquered polyester acetate tracing papers using a 0.05” lead pencil. This study assessed the associations of upper lip strain and upper pharynx size with selected cephalometric measures. The data was analyzed using SPSS (Statistical Package for Social Science, Ver.10.0.5) package. Results: The increased upper lip strain was associated with a forwardly placed maxilla, increased mandibular plane angle and upper pharynx size was associated with decrease in mandibular size (mandibular corpus size), increase in gonial angle (Ar-Go-Gn), decrease in middle third of face (N- ANS) and increase in lower jaw anterior face height (ANS- Me). Also, the dental effect of increase in the degree of mandibular incisor proclination relative to mandibular plane was observed. Conclusion: With an increase in upper-lip strain and decreased upper pharynx size, forward maxillary placement, retrognathic mandible, downward and backward rotation of the mandible, decreased middle third of face, increase in lower anterior face height and increase in degree of mandibular incisor proclination relative to mandibular plane were observed. It was inferred from the present study that a decreased upper airway affects the craniofacial skeletal growth pattern in children.

The orthopantomogram (OPG) is a common dental screening radiograph that has multiple implications. However, lateral cephalogram is the investigation of choice for the assessment of vertical facial pattern. Objective: The aim of the current study was to investigate the validity of an OPG parameter i.e. panoramic gonial angle (PGoA) for the assessment of the vertical facial pattern. Methods: A cross-sectional study was conducted on the pretreatment OPG and lateral cephalograms of 200 orthodontic patients aged 15-40 years. The PGoA was measured on both sides and an average was used for statistical analysis. The Pearson’s correlations of PGoA were measured with cephalometric gonial angle (CGoA), SN-GoGn, MMA, FMA, LAFH/TAFH% and PFH/TAFH%. The diagnostic test statistics were applied for PGoA against gold standard “definitive diagnosis (DD)” derived from SN GoGn and FMA. A p-value ofResults: The mean CGoA was 121.18º ± 5.16º which was significantly different (pConclusion: The current study identifies PGoA as a valid tool for the assessment of vertical facial pattern of orthodontic patients with its normal value 116º±3º in our sample.

Lower third molars (M3M) are the most frequent impacted teeth. The aim of this study was to evaluate the correlation between M3M position and gonial angle. A retrospective cross-sectional study was conducted. The study population included patients with unilateral or bilateral M3M and underwent Cone Beam Computed Tomography. A morphometric analysis of the mandible was performed after three-dimensional reconstruction, recording gonial angle (GA), ramus high, ramus width, ramus divergency, and retromolar space. GA was the primary predictor variable. The primary outcome variable was the position of M3M analyzed in sagittal, axial, and coronal planes. Descriptive, bivariate, and multiple regression statistics were performed (p < 0.05). Study sample included 172 patients (mean age: 26.3 ± 4.6 years); 266 M3Ms were analyzed. The average GA was 122.6° ± 4.8°. A reduced GA value was significantly associated with a deeply impacted M3M in the ramus. With a progressive decrease of GA, M3M assumed a more horizontal position closer to the mandibular canal (p < 0.05). A lower GA showed a reduced retromolar space with more complex impacted M3M (p < 0.05). The results confirm a statistically significant correlation between GA and the position of M3M. Higher incidence of impacted M3M was related to a reduction of the GA value.

Background About 60% of individuals with atopic dermatitis (AD) develop their first manifestation during infancy. Cow’s milk (CM) exposure is considered to be a risk factor for AD.Objective To evaluate for an association between cow’s milk exposure and atopic dermatitis in infants > 6 months of age.  Methods This cross-sectional study consisted of subjects from a previous study and new subjects recruited in order to meet the minimum required number of subjects. Our study population comprised 120 infants, born between 1 February and 30 November, 2012 in Sanglah Hospital, Denpasar. Subjects were divided into CM and non-CM groups and analyzed for their risk of AD. Subjects were included to CM group if they were fed with cow’s milk/formula  and included to non-CM group if they were breastfeed exclusively in the first six months of life. Other possible risk factors were assessed by multivariate analysis. Results One hundred twenty subjects were enrolled and analyzed (59 in the CM and 61 in the non-CM groups). The prevalence of AD was 30%. Multiple logistic regression analysis revealed a significant association between CM exposure and AD, with odds ratio (OR) 2.37 (95%CI 1.036 to 5.420; P=0.04). In addition, maternal diet including eggs and/or cow’s milk during the breastfeeding period was significantly associated with AD in infants (OR 3.18; 95%CI 1.073 to 9.427; P=0.04).Conclusion Cow’s milk exposure is significantly associated with atopic dermatitis in infants  > six months of age.

Background: Acceptance of the COVID-19 vaccine will play a major role in combating the pandemic. Healthcare workers (HCWs) are among the first group to receive vaccination, so it is important to consider their attitudes about COVID-19 vaccination to better address barriers to widespread vaccination acceptance. Methods: We conducted a cross sectional study to assess the attitude of HCWs toward COVID-19 vaccination. Data were collected between 7 October and 9 November 2020. We received 4080 responses out of which 3479 were complete responses and were included in the final analysis. Results: 36% of respondents were willing to take the vaccine as soon as it became available while 56% were not sure or would wait to review more data. Only 8% of HCWs do not plan to get vaccine. Vaccine acceptance increased with increasing age, education, and income level. A smaller percentage of female (31%), Black (19%), Lantinx (30%), and rural (26%) HCWs were willing to take the vaccine as soon as it became available than the overall study population. Direct medical care providers had higher vaccine acceptance (49%). Safety (69%), effectiveness (69%), and speed of development/approval (74%) were noted as the most common concerns regarding COVID-19 vaccination in our survey.

AbstractThe coronavirus disease of 2019 (COVID-19) has caused a global pandemic and led to nearly three million deaths globally. As of April 2021, there are still many countries that do not have COVID-19 vaccines. Before the COVID-19 vaccines were developed, some evidence suggested that an influenza vaccine may stimulate nonspecific immune responses that reduce the risk of COVID-19 infection or the severity of COVID-19 illness after infection. This study evaluated the association between influenza vaccination and the risk of COVID-19 infection. We conducted a retrospective cross-sectional study with data from July 1, 2019, to June 30, 2020 with the Claims data from Symphony Health database. The study population was adults age 65 years old or older who received influenza vaccination between September 1 and December 31 of 2019. The main outcomes and measures were odds of COVID-19 infection and severe COVID-19 illness after January 15, 2020. We found the adjusted odds ratio (aOR) of COVID-19 infection risk between the influenza-vaccination group and no-influenza-vaccination group was 0.76 (95% confidence interval (CI), 0.75–0.77). Among COVID-19 patients, the aOR of developing severe COVID-19 illness was 0.72 (95% CI, 0.68–0.76) between the influenza-vaccination group and the no-influenza-vaccination group. When the influenza-vaccination group and the other-vaccination group were compared, the aOR of COVID-19 infection was 0.95 (95% CI, 0.93–0.97), and the aOR of developing a severe COVID-19 illness was 0.95 (95% CI, 0.80–1.13). The influenza vaccine may marginally protect people from COVID-19 infection.

Abstract Objective: To estimate the prevalence of periodontal disease with different indices. Methods & materials: The study population consisted of multistage stratified random sample of 1300 subjects from total population of district Ghaziabad. A cross-sectional study was conducted with multi stage stratified random sampling techniques to select the sample population. The subjects were divided into different age groups and the periodontal assessment was made on the basis of CPITN index and ESI Index. Results: The CPITN has shown to estimate incorrect periodontal disease prevalence because of its underestimation of the disease severity. A huge difference was noticed in the prevalence rate of periodontitis when subjects were examined with ESI index. Conclusion Periodontal disease was found to be highly prevalent in the study population and severity of disease increased with age. More number of subjects in younger age group were found to be healthy.

Background: Restless legs syndrome (RLS) is characterized for an uncomfortable sensation in legs and an irresistible desire to move them. This disorder has been more recently recognized in patients with myasthenia gravis (MG) and can interfere with the quality of life (QOL). Objectives: The aims of this study are to describe the prevalence of RLS and its severity and influence on the QOL in patients with MG. Method: This was a cross-sectional study conducted from May to June 2016 in Recife, Brazil. A sample of 42 patients was interviewed using a sociodemographic questionnaire, MG QOL questionnaire-15 and The RLS Rating Scale. Results: RLS was present in 47.6% of patients and of these 40.5% met moderate to severe RLS criteria. Patients were 45 years on average (SD ± 14.4) and women represented 57.1% of the study population. Among patients with RSL, the quality-of-life scores were worse (p = 0.010) on average. There was no association of RLS with the duration of MG, use of immunosuppressant or clinical conditions that could mimic the occurrence of RLS. Conclusion: RLS is a prevalent condition in patients with MG, and may be severe enough to negatively impact QOL.
