Photoanthropometry quantify the facial proportions of an individual facilitating the comparison of facial patterns for human identification. The coordinates and vertical distances in pixels of the photoanthropometric landmarks on images of the same individual in frontal and profile views were analyzed and compared. A total of 116 pairs of photographs of Brazilian individuals were evaluated. The photographs were adjusted in size and rotation, and marked in the software Two-dimensional Forensic Facial Analysis System. For each face, 16 landmarks were considered: glabella (g), nasion (n), ectocanthion (ec), pronasale (prn), subnasale (sn), alare (al), cheilion (ch), upper lip (ls), lower lip (li), stomion (sto), labiomental (lm), gnathion (gn), superaurale (sa), subaurale (sba), postaurale (pa) and upper ear lobe (slb); the x- and y-coordinates of each landmark were obtained. Twenty-seven vertical distances between the points were proposed, which were measured by subtracting the values of the y-coordinate. The data were analyzed descriptively and inferentially using the Kolmogorov-Smirnov test, intraclass correlation coefficient (ICC) and Mann-Whitney test (α=5%). The mean age of the sample was 25.9 years (± 4.7), and 50.9% (n=59) were males. When the coordinates were evaluated, a low correlation was obtained between the images (ICC<0.4). Of the 27 proposed measures, 77.7% (n=21) indicated agreement between the images in the two views (p>0.05). A comparison of ls-g, sa-ec, pa-ec, slb-ec, sba-sa and slb-sa showed disagreement between the images. Therefore, there is agreement between the facial measures in the frontal and lateral images, except for ls-g and for the distances between the ear landmarks.

Abstract The Kolmogorov–Smirnov goodness-of-fit test is used in many applications for testing normality in climate research. This note shows that the test usually leads to systematic and drastic errors. When the mean and the standard deviation are estimated, it is much too conservative in the sense that its p values are strongly biased upward. One may think that this is a small sample problem, but it is not. There is a correction of the Kolmogorov–Smirnov test by Lilliefors, which is in fact sometimes confused with the original Kolmogorov–Smirnov test. Both the Jarque–Bera and the Shapiro–Wilk tests for normality are good alternatives to the Kolmogorov–Smirnov test. A power comparison of eight different tests has been undertaken, favoring the Jarque–Bera and the Shapiro–Wilk tests. The Jarque–Bera and the Kolmogorov–Smirnov tests are also applied to a monthly mean dataset of geopotential height at 500 hPa. The two tests give very different results and illustrate the danger of using the Kolmogorov–Smirnov test.

Understanding the problem of upper arches rehabilitation with implants in relation to the complain of lack of lip support, this study was designed to assess the potential of hyaluronic acid (HA) to increase lips volume and to fill the nasogenian groove in this group of patients. One hundred patients with rehabilitated maxilla with implant-supported hybrid fixed total prosthesis were selected. Of these, 86 attended the initial consultation and eight individuals were included in the study. The sample inclusion criteria were use of implant-supported fixed prosthesis in the maxilla with complaint of thin lips and deepening of the nasogenian groove and patients who agreed to participate of the study. Linear and angular measurements were drawn on initial an after procedure teleradiographies in order to assess lip protrusion before and after hyaluronic acid filling. Also standardized photographs were taken before and after the procedures, which were assessed by dentists and lay people. The participants of the study answered a questionnaire in order to assess the degree of satisfaction with the procedure. Hyaluronic acid filling presented significant differences (t1-t2) for upper and lower lip protrusion p= 0.001 and p=0.02, respectively. For the upper lip, the mean protrusion was 0.76mm + 1.88 (t1) before the filling with hyaluronic acid procedure and after filling the mean protrusion was 3.45mm + 1.58 (t2). Independent evaluators and practitioners assessed the facial profiles after the filling with HA, mostly as medium and significant better alterations. It can be concluded that lip and nasogenian sulcus filling in individuals rehabilitated with implant-supported total fixed implants increased self-esteem and provided close to normal lip protrusion.

OBJECTIVE: The aim of this study was to analyze the facial features of patients with Down syndrome, such as projection of the nose, projection and length of upper and lower lips, projection of soft pogonion and to compare them with the standardized analysis by Ayala and Gutierrez1. METHODS: The sample consisted of 20 patients with Down's Syndrome, between 8 and 13 years-old of both genders. The analysis was performed by one orthodontist, using lateral cephalograms and photography in natural head position. For statistical analysis, the mean values of linear measurements within a range of 95% were used. RESULTS: The mean (± standard deviation) showed a nasal projection of 10.1 mm (2.4), the upper and lower lip in front of the vertical reference line, subnasal and soft pogonion with a retrusion of 4.95 mm (4.6). The length of the upper lip showed a value of 20.2 mm (2.4) and the length of the lower lip of 42.5 mm (2.9). CONCLUSION: The facial analysis of patients with Down's Syndrome, compared with Ayala and Gutierrez1, showed smaller nasal projection, greater projection of the upper and lower lip, but lengths, and retrusion of the soft pogonion, similar to those of normal individuals

Objective Lip position has become one of the most important soft tissue analyses as it influences the occlusion, tooth stability and facial aesthetic. Hence, the objective of this study was to compare the short-term and long-term sagittal lip positions/changes using the Burstone line (B-line).   Methods The sample consisted of 18 Caucasoid females only (14 extractions, 4 non-extractions) who were successfully treated with edgewise appliances. All the patients were evaluated before treatment (T1),at the end of active treatment (T2), and at a long-term follow-up observation (T3). The mean age at commencement was 13.2 years with the range of 10.5-19 years. The linear distance between the tip of the lips and the B-line were measured.   Results T1-T2 time intervals showed the upper lip underwent a mean change of 1.272 mm relative to the B-line (-32.8%) which was statistically significant. The lower lip showed a mean change of 1.549 mm (-22.2%), but these changes were not statistically significant. Lip protrusion relative to the B-line continued to reduce during the long term follow up period. The upper lip showed slight changes (-9.2%), whereas the lower lip demonstrated greater change (-53.8%).   Conclusion Using B-line, the sagittal soft tissue lip positions were more retrusive on the long-term follow-up records for both extraction and non-extraction cases, their values were not very different from the normal values of the untreated cases. Although the differences were not statistically significant,  upper lips were retrusive post treatment from T1-T2, while were statistically significant the lower lips were retrusive from T1-T2.

Introduction: Taro village has a higher risk of gathering the people since it is one of the most popular tourism sectors in Bali hence increasing the potential to spread coronavirus disease 2019 (COVID-19). The level of knowledge plays an important role in determining whether the society is ready to implement the health protocols or not. This community service aims to evaluate the level of knowledge regarding COVID-19 health protocols in the tourism sector in the Taro village. Method: This research was conducted using a quasi-experimental one-group pretest-posttest design in Taro village, Bali. Respondents filled out the questionnaire before and after counseling. The questionnaire consisted of 10 items of knowledge. The participants were Taro’s residents who met inclusion and exclusion criteria. A total of 31 respondents were taken. The data were tested for normality with the Kolmogorov-Smirnov test and analyzed with paired T-test using the IBM SPSS statistics version 25. Significance was determined at a 5% level (P-value ≤0.05). Results: A total of 31 valid filled-questionnaires were collected. In general, Taro’s residents’ knowledge regarding COVID-19 health protocol in the tourism sector was sufficient, but some topics are still insufficient. The mean score before counseling was 79,03 ± 1,340 while the mean score after counseling was 86,13 ± 1,366. There was a significant difference (p<0,05) on level of knowledge (p=0,000) before and after counseling. Conclusion: There was a significant difference in the level of knowledge of Taro village’s residents toward COVID-19 health protocols in the tourism sector before and after counseling.

Introduction: The aim of our study was to examine whether outdoor activity influences the prevalence of myopia in schoolchildren.Materials and methods: 5601 Polish students of elementary and secondary schools (2688 boys and 2913 girls), 6–18 years of age (mean 11.9 ±3.2 years) were examined. In every student cycloplegia after 1% tropicamide was performed. The mean spherical equivalent (SE) was calculated after examination of both eyes. Time spent on outdoor activity was evaluated based on a questionnaire. The obtained results were typed into an Excel spreadsheet and analyzed statistically using Statistica 10 software. Non-parametric tests were used due to the SE distribution being significantly different from normal distribution in the Kolmogorov–Smirnov test. The Spearman rank correlation coefficient (Rs) was used to evaluate the strength of the correlation between these variables. A p-value less than 0.05 was considered significant.Results: It has been established that with the increase in time spent on outdoor activity, the spherical equivalent of the examined students significantly increases, but the correlation is very weak (Rs = +0.036, p = 0.007).Conclusion: Outdoor activity slightly reduces the prevalence of myopia in schoolchildren.

Background: Schizophrenia is a severe psychiatric condition with devastating consequences for the individual's functionality and leading to severe disability. Lack of insight and non-adherence to treatment remain the most important factors in the progression of the disease to chronicity. Despite their proven effectiveness in preventing relapses, reducing morbidity and mortality, long-acting injectable antipsychotics (LAIs) are still underused. One of the causes invoked is the lack of guidelines or protocols for initiating LAIs.Objective: The aim of this article is to present Rating Opportunity for Long-Acting Injectable Antipsychotic Initiation Index (ROLIN), a clinician-rated index that rates the important factors of the disorder across seven items: age, duration of illness, relapses, antipsychotic treatment response, family support, antipsychotic existing formulation and adherence.Method: A retrospective study in which all patients with schizophrenia discharged on oral antipsychotics without LAIs treatment lifetime were evaluated with ROLIN for opportunity for LAIs initiation.Results: Of 225 consecutive patients, 126 patients (56%) had a strong indication for initiating LAI (score between 25 and 35). Kolmogorov-Smirnov test was used for checking the normal distribution of values (95% CI for the mean = 9.5781 to 20.4219; 95% CI for the median = 6.5920 to 24.8161; SD = 9.7907; Coefficient of Skewness = 0.0743; Coefficient of Kurtosis = −1.1377).Conclusion: This paper proposed an instrument designed to improve treatment in schizophrenia using a simple conceptual model which integrates important predictors of good or poor outcomes.

Background:There is an increasing patient expectation for better esthetics, manifesting through anatomical harmony, projection, and volume of the upper lip relative to the lower lip, in patients with cleft deformity. The aim of this study is to investigate the outcome of vermilion augmentation using autologous dermofat graft (DFG) to enhance the lip using both quantitative and qualitative assessment.Methods:Patients with secondary cleft lip deformity who received the surgical treatment in our institution from 2015 to 2018 were recruited. Panel assessment was performed on standardized preoperative and postoperative digital photographs. A patient questionnaire was used for the reported outcome. Image processing and analyses were applied to measure the lip change. Statistical analyses were performed.Results:A total of 91 patients were included. The mean age at operation was 22.7 years, and postoperative follow-up was 3.6 years. There were no complications in the study group. The panel assessment showed significant improvement ( P < .00001) on upper lip vermilion in both frontal and lateral profile views. Ninety-five percent of patients reported improvement of the upper lip projection and volume. Quantitative image analysis showed an increase in the upper lip vermilion ratio in 97% of the cases in frontal views and improvement of the vermilion projection in 87% of the cases in the superimposed lateral views.Conclusions:The use of DFG is an effective and reproducible method for vermilion augmentation and aesthetic enhancement in patients presenting with upper lip insufficiency relative to the lower lip.

Objective: To investigate the variation between the non-syndromic cleft lip and/or palate (NSCLP) and non-cleft (NC) subjects in relation to the lip morphology (LM) and nasolabial angle (NLA). Materials and Methods: Lateral cephalogram (Late. Ceph.) of 123 individuals (92 NSCLP [29 = bilateral cleft lip and palate (BCLP), 41 = unilateral cleft lip and palate (UCLP), 9 = unilateral cleft lip and alveolus (UCLA), 13 = unilateral cleft lip (UCL)], and 31 NC) who did not undergo any orthodontic treatment were investigated. By WebCeph, an artificial intelligence- (A.I.) driven software, 2 (two) parameters of LM, namely upper lip to E line (LM-1) and lower lip to E line (LM-2), and NLA analysis was carried out for each individual. Multiple tests were carried out for statistical analysis. Results: The mean ± SD observed for LM-1, LM-2, and NLA for NC individuals were 1.56 ± 2.98, 0.49 ± 3.51, and 97.20 ± 16.10, respectively. On the other hand, the mean ± SD of LM-1, LM-2, and NLA for NSCLP individuals were 4.55 ± 4.23, 1.68 ± 2.82, and 82.02 ± 14.66, respectively. No significant variation was observed with respect to gender and side. NSCLP (different types) and NC individuals showed significant disparities in LM-1 and NLA. Conclusion: It can be concluded that parameters of lip morphology such as LM-1, LM-2, and NLA vary among NSCLP and NC individuals.

Aim: To investigate the differences of corneal biomechanic characteristics using Ocular Response Analyzer (ORA, Reichert; USA) on type 2 diabetics and healthy subjects. Methods: One hundred eyes of 100 subjects (between the ages of 17-91) who applied to Adnan Menderes University’s Ophthalmology Clinic between January-March 2015 were included in this study, 50 diabetics (Group 1) and 50 healthy controls (Group 2). The eyes included in the study were randomly chosen. Corneal Hysteresis (CH), Corneal Resistance Factor (CRF), Goldmann correlated Intraocular Pressure (IOPg) and corneal compensated Intraocular Pressure (IOPcc) of patients were measured by ORA. Detailed ophthalmological examinations were done for every subject. Kolmogorov-Smirnov test was used to analyze the distribution of quantitative variables and t test was used for the data that were normally distributed. Any p value <0.05 was considered as statistically significant. Results: The mean ages were 63.3±9.0 and 61.7±11.6 in Group 1 and 2, respectively (p=0.459). 25 (50.0%) were female, 25 (50.0%) were male in Group 1 and 26 (52.0%) were female, 24 (48.0%) were male in Group 2 (p=1.000). Mean IOPcc values were 17.8±3.6 (12.1-29.0) and 16.0±3.1 (10.9-23.8) mmHg (p=0.006); mean IOPg values were 16.9±3.5 (10.9-25.9) and 15.4±2.9 (9.0-24.7) mmHg (p=0.032); mean CH values were 9.9±1.5 (6.1-13.3) and 10.5±1.7 (6.5-15.7) (p=0.080) and mean CRF values were 10.4±1.6 (7.5-14.0) and 10.5±1.7 (6.6-15.4) (p=0.730) in Groups 1 and 2, respectively. Conclusions: There was no any statistical difference between the groups in terms of CH and CRF. However, mean CH and CRF values were found less in diabetic group. Corneal biomechanical differences seen in diabetic patients may be associated with a statistically significantly higher IOP measurements.
