Malocclusion is very closely related to the disharmony of mesiodistaltooth-width with dental arches. It is important to know the mesiodistaltooth widths before establishing the diagnosis and planning oforthodontic treatment. The ultimate goal of orthodontic treatment isfacialesthetic, which is supported by a balanced soft tissue profile. The aim ofthis cross sectional study was to investigate the correlation betweenmesiodistal tooth widths with the convexity of soft tissue profile. Theresult of the study can be used as a reference and guidance inestablishing orthodontic diagnosis and treatment planning. The numberof sample was 50 (18 males and 32 females), aged 18-27 years old.Criteria for sample selection comprised absence of interproximalcaries/filling, no tooth deformity, aged over 17 years, never undergoorthodontic treatment, the presence of teeth from the right first molarthrough the left first molar, both upper and lower, Buginese orMakassarese people, and Class I Angle malocclusion. Tooth sizemeasurements were performed on study models by using slidingcaliper. The photo of each subject was taken cephalometrically. Theangular measurement was performed on cephalogram, using Subtelny'sanalysis. The soft tissue convexity degree was represented by N-SnPog.The data was processed using SPSS program and tested byindependent t-test and correlation. It can be concluded that the meanvalue of mesiodistal width on males was greater that those on females(p<0.05), the mean of facial convexity degree on males (159.05°) wassmaller than those on females (162.77°), which was different significantly (p<0.05), and there was a very weak correlation (r<0.25) oralmost no correlation between mesiodistal tooth-width and the degree ofsoft tissue facial profile, and it was not significant statistically (p>0.05).

Background The right atrial longitudinal strain (RALS) has been shown to be a useful parameter to define right atrial (RA) subclinical dysfunction in several cardiovascular disorders prior to changes in traditional RA two dimensional and volumetric parameters. There is a scarcity of data regarding normal values for RALS in a normal African population. Objectives We sought to establish normal values for RALS and its correlation with age, in a Sub-Saharan black African population. Methods This was a retrospective cross-sectional study of 100 normal individuals (recruited as controls for another study) performed at Chris Hani Baragwanath Hospital (2017-2019). All echocardiographic measurements were done as per standard guidelines. RALS was measured using Philips QLAB 9 (Amsterdam, The Netherlands) speckle-tracking software. Results Median age was 37.5 years (IQR 26- 46, 60% females). The mean right atrial volume indexed to body surface area (RAVI) was 19.5 ± 5.7 mL/m and the mean RALS was 32.7 ± 10.5%. There was a trend towards decreasing RALS with age (r=-0.15, P=0.129) with no change in RAVI with age ( P=0.27). Males had a tendency towards higher RAVI and RALS measurements compared to females (20.8 ± 6.3 mL/m and 18.7 ± 5.2 mL/m , P=0.07: 34.6 ± 9.6% and 31.4 ± 10.9 %, P=0.141, respectively) . BMI was an independent predictor of RALS on multivariate analysis ( r= -0.43, P =0.003) Conclusion We have defined the normal reference values for RALS in a black population. RALS tended to decrease with age prior to change in RAVI and can serve as a marker of subclinical RA dysfunction . BMI was an important determinant of RALS.

Abstract Background Few studies have focused on patient-related factors in analyzing long-term functional outcome and health-related quality of life (HRQoL) in patients with postoperative lower extremity soft tissue sarcoma (STS). Objective The purpose of this study was to investigate factors associated with postoperative functional outcome and HRQoL in patients with lower extremity STS. Methods This cross-sectional study was performed in a tertiary referral center using the Toronto Extremity Salvage Score (TESS), Quality-of-Life Questionnaire (QLQ)-C30 and 15 Dimension (15D) measures. Functional outcome and HRQoL data were collected prospectively. All patients were treated by a multidisciplinary team according to a written treatment protocol. Results A total of 141 patients who had undergone limb-salvage surgery were included. Depending on the outcome measure used, 19–51% of patients were completely asymptomatic and 13–14% of patients had an unimpaired HRQoL. The mean score for TESS, 15D mobility score, and QLQ-C30 Physical Functioning scale were 86, 0.83, and 75, respectively, while the mean score for 15D was 0.88, and 73 for QLQ-C30 QoL. Lower functional outcome was statistically significantly associated with higher age, higher body mass index (BMI), and the need for reconstructive surgery and radiotherapy, while lower HRQoL was statistically significantly associated with higher age, higher BMI, and reconstructive surgery. Conclusion Functional outcome and HRQoL were generally high in this cross-sectional study of patients with STS in the lower extremity. Both tumor- and treatment-related factors had an impact but patient-related factors such as age and BMI were the major determinants of both functional outcome and HRQoL.

Abstract Background Medico-legal or forensic autopsy is a special type of autopsy performed under the orders of a legal authority in circumstances involving unnatural, suspicious or criminal deaths. Gross and histopathological studies of viscera in medico-legal autopsies have been observed to serve as crucial tool in the detection of undiagnosed disease conditions and the resulting findings may closely represent the general population. Methods A prospective cross sectional study was carried out at the Muhimbili National Hospital (MNH) department of pathology, to medico-legal autopsies received at the MNH mortuary. The study included 103 cases in an eight month period. Both lungs were weighed for each case and tissue samples were collected from each lobe, in both lungs. Other gross findings were observed and recorded. Tissue sections were made and stained with hematoxylin and eosin and evaluated under a microscope. Results Out of 103 cases studied, 88.3% were male with mean age of 35.8 + 16.6 years. In females, the mean age was 31.6 + 10.4 years. The mean weight of lungs was found to be 627.3 + 138.5g and 591.7 + 129.7g for the right and left lung, respectively, in males. In females, the mean weight of lungs was 616.7 + 166.1g and 583.3 + 155.8g for the right and left lung, respectively. More than half (53.4%) of lung samples had some pathological disease, and the leading diagnosis was pulmonary congestion/oedema (22.3%) followed by lobar pneumonia (18.5%). Age was found to relate with the observed histological diagnosis of the lungs. Conclusion Males, especially the youth and adults are the main victims of medico-legal deaths. The study also revealed high prevalence of undiagnosed lung diseases in victims of medico-legal deaths. These findings may reflect heavy burden of lung diseases in the general population.

Objective: To evaluate the relationship between inner canthal distance and maxillary anterior teeth width withrespect to age, gender and ethnicity. Study Design: Cross sectional study. Place and Duration of Study: Altamash Institute of Dental Medicine, Karachi, from Aug 2019 to Jan 2020. Methodology: One hundred participants from both genders with full permanent dentition, no interdental space or pathology and facial symmetry were included in this study. The measurements were carried out with digital Vernier caliper. SPSS-25 was used for statistical analysis. Results: The mean ± SD of inner canthal distance and width of maxillary anterior teeth were 2.99cm ± 0.46and 3.82cm ± 0.35 respectively. A significant difference was found between gender (p=0.037) and inner canthaldistance. The maxillary anterior teeth width and inner canthal distance varies amongst different ethnicities(p=0.01). The inner canthal distance does not vary with advancing age (p=0.87) whereas width of maxillaryanterior teeth varies (p=0.04). A weak correlation value of 0.47 was found between inner canthal distance andmaxillary anterior teeth width. Conclusion: This research suggests that there is a weak relationship between inner canthal distance and maxillary anterior teeth width. Therefore, a multiplication ratio of 1.27 is advised to get combined mesiodistal width of maxillary anterior teeth. Additionally, the value of both differs in various local ethnicities. Inner canthal distance does not vary with age though has significant gender disparities while maxillary anterior teeth width remains constant.

Abstract Background Infancy is the of a child’s visual development. Refractive errors, especially myopia, are a common vision disorder. Thus, the purpose of this study was to explore refractive errors and risk factors for myopia among infants aged 1–18 months in Tianjin, China. Methods A total of 583 infants aged 1–18 months participated in this cross-sectional study at Tianjin Women’s and Children’s Health Center in China from February 2019 to November 2020. Each infant received a complete ophthalmologic examination, and myopia-related risk factors were investigated using a questionnaire. Results A total of 583 eligible infants participated in this study, including 312 (53.5%) boys and 271 (46.5%) girls. There were 164 (28.1%) premature born infants. The mean age was 6.59 ± 4.84 months (range, 1–18 months). The mean spherical equivalent (MSE) for the right eye was 1.81 D ± 1.56 D, with no difference related to sex (P = 0.104). Refractive state showed an average hyperopia of +2.74 ± 1.74 D at early ages, followed by a trend toward less hyperopia, finally reaching +1.35 ± 1.44 D at the age of 18 months (P ≤0.001). The overall prevalence rates of myopia (MSE ≤ −0.50 D), emmetropia (−0.50 D<MSE<+0.50 D), hyperopia (MSE ≥ +2.00 D), and astigmatism (≥ 1.50 D) were 5.1%, 10.8%, 42.7%, and 49.9%, respectively. The chi-square tests showed that gender, gestational age ≥37 weeks, winter birth, prenatal exposure to environmental tobacco smoke, and parental history of high myopia were associated with children’s myopia (P = 0.022, P = 0.023, P = 0.038, P = 0.015, P<0.001, respectively). Conclusions Among Chinese infants in Tianjin, hyperopia and astigmatism were the most frequent refractive errors, and the diopter was lower in individuals with higher age. In a small number of infants with myopia, genetic factors and the prenatal environment were associated with the early onset of myopia.

ABSTRACT Objective: The present study is intended to add a new parameter that would be useful in orthodontic clinical evaluation, treatment planning, and determination of vertical dimension (at occlusion). Materials and Methods: Standardized videographic recording of 79 subjects during posed smile was captured. Each video was then cut into 30 photos using the free studio software. The widest commissure-to-commissure posed smile frame (posed smile width [SW]) was selected as one of 10 or more frames showing an identical smile. Lower third of the face is measured from subnasale to soft tissue menton using a digital vernier caliper. Two values were then compared. Ratio between lower facial height and posed SW was calculated. Results: The co-relation between smiling width and lower facial height was found to be statistically significant (P < 0.01). The ratio of lower facial height and smiling width was calculated as 1.0016 with a standard deviation (SD) = 0.04 in males and 1.0301 with an SD = 0.07 in females. The difference between the mean lower facial height in males and females was statistically significant with a t = 10.231 and P = 0.000. The difference between the mean smiling width in males and females was also statistically significant with a t = 5.653 and P = 0.000. Conclusion: In class I subjects with pleasing appearance, normal facial proportions, normal overjet and overbite, and average Frankfort mandibular angle, the lower facial height (subnasale to soft tissue menton) is equal to posed SW.

Objectives: We aim to investigate the involvement of the choroid and retinal nerve fiber layer (RNFL) in COVID-19 patients using spectral domain optical coherence tomography. Methods: This cross-sectional study was conducted between April and June 2020. 40 patients (23 female and 17 male) with COVID-19 and 42 healthy individuals (26 female and 16 male) were included in the study. The OCT scans were performed 4 weeks after the COVID-19 diagnosis. Results: In the COVID-19 group, in the right eyes, the mean nasal choroidal thickness was 295.70 ± 7,046 μm ( p = 0.017), mean subfoveal choroidal thickness was 333.25 ± 6,353 μm ( p = 0.003), mean temporal choroidal thickness was 296.63 ± 6,324 μm ( p = 0.039), and mean RNFL was 89.23 ± 1.30 μm ( p = 0.227). In the left eyes, mean nasal choroidal thickness was 287.88 ± 9,033 μm ( p = 0.267), mean subfoveal choroidal thickness was 333.80 ± 9,457 μm ( p = 0.013), mean temporal choroidal thickness was 298.50 ± 9,158 μm ( p = 0.079), and mean RNFL was 89.48 ± 1,289 μm ( p = 0.092). Compared with the control group, the patient group had significant thickening of the choroidal thickness in all quadrants of the right eyes, and significant thickening of the subfoveal choroidal thickness in the left eyes. There was no significant difference in the RNFL thickness between groups ( p > 0.05). Conclusion: COVID-19 may cause a subclinical involvement in the choroidal layer.
