Background: Panoramic view of radiograph or Orthopantomogram (OPG) is useful in the aspect of surgery done in mandible, as many visible landmarks can be found in a single tomographic image. Objectives: To evaluate the visibility of anatomical structures of mandible in OPG and to determine the relationship of age and gender with this. Materials and Methods: It was a cross-sectional study and was conducted in dental OPD of Noakhali General Hospital from January 2019 to June 2019, six-month period. Data were analyzed by SPSS version 20. Results: A Total of 272 OPGs were examined of patients (female 165, male107), having age range of 7-90 years. Here highest visible structure was mandibular canal (about 97.4%) followed by mental foramen and mandibular foramen, where visibility was 92.3% and 87.5% respectively. Anterior loop of mental nerve and incisive canal were seen in 33.5% and 31.6% cases respectively. Only in 15.1% OPG, lingual foramen was visible. There is no significant relationship between gender and visibility of structures (p>0.05). Age and visibility of landmarks showed significant relation only in case of mental foramen and mandibular canal (p<0.05). Conclusion: Panoramic view or orthopantomogram is very efficient to detect many anatomic points in adults. KYAMC Journal Vol. 11, No.-3, October 2020, Page 133-136

Aims: A descriptive type of cross-sectional study was conducted at the department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka, Bangladesh during January 2010 to December 2012. The aim of the study was to test the hypothesis that there were no differences between adults with class I crowded, class III and class I normal occlusions in respect to width of the maxillary and mandibular arches and gender comparisons. Materials and Methods: In this study, 82 pairs of study models were selected from the patients and students of the Department of Orthodontics and Dentofacial Orthopedics at Dhaka Dental College and Hospital and were divided into three groups. Twenty seven (27) pairs of dental casts with normal occlusion, 25 pairs with class I crowded and another 30 pairs with class III malocclusions that included almost equal numbers of male and female samples. Results: Among different arch dimensions, maxillary arch widths were found to have significantly smaller in class I crowded and class III malocclusions compared to normal class I occlusion. Conclusion: The hypothesis was partially rejected by the findings of the study. It may be suggested that Orthodontist who is aware of these differences in arch dimension will be beneficial to diagnose and make planning of treatment of orthodontic cases more accurately.

Dental Arch Width

Aim: Objectives: To analyze variations in dental arch width in relation to oral habits.   Materials and Methods : Cross sectional  study was carried out Department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka with a total number of 600 primary school children of 3-6 years ages of Bangladeshi population. Results: This study was a cross sectional study conducted among the 600 children with 3-6 years old prima- ry school children of Bangladeshi population. According to present study, bottle feeding causes significant reduction in maxillary intercanine width and mouth breathers show significant reduction of both arches. Conclusion: It was observed that the children who had used a bottle had a significant reduction in maxillary intercanine width. Breathing through mouth appeared to be associated with a reduction in the size of both arches. This was more significant in the maxillary intercanine , mandibular  intercanine and mandibular molar widths. Therefore to prevent malocclusions, the public should be informed of the harm caused by certain oral habits, the benefits of breast-feeding, and the need to correct bad habits at early life.

Abstract Introduction The study of larynx lesions is of great importance. More than 50% of people with vocal complaints have benign vocal fold alterations and some require surgery. Objective To determine which factors are related to surgical recurrence of benign laryngeal lesions and to determine which videolaryngoscopic diagnoses are related to the risk or protection of surgical relapses over time. Methods Observational, analytical, cross-sectional study with retrospective data collection of 1,383 surgeries in 1,301 patients. Results The mean age at the first surgery was 39.2 years old. The predominant gender was female (65.6%).There were 396 cases of polyps (25.34%), 349 cases of cysts (22.33%), 261 cases of Reinke edema (16.7%), 175 cases of nodules (11.2%), 153 cases of minor structural alterations (MSAs) (9.79%), 94 cases of leukoplakia (6.01%), 77 cases of granulomas (4.93%) and 58 cases of pseudocysts (3.71%). The age presented statistical significance with the risk of surgical relapses (p = 0.016). Male gender was associated with the greatest chance of relapse.Diagnosis of granuloma (p < 0.001) and of leukoplakia (p < 0.001) were associated with a higher risk of surgical recurrence. Cyst diagnosis was associated with protection (p = 0.015) in relation to the chance of further surgeries. Patients with associated lesions, bilaterals or voice professionals did not present a statistically significant association with surgical recurrence. Conclusion Age and gender are statistically related to the increase of surgical relapses. Leukoplakia and granuloma are associated with increased surgical relapses. Patients submitted to cyst microsurgery appear to be protected against surgical recurrence.

Rubella Vaccination

Background: Countries that have good rubella surveillance, report ∼10,000–20,000 rubella cases annually. In India, not many cases of rubella are reported. The Hebballi Agasi ward of Dharwad district in Karnataka state, India, reported rubella cases on the last week of January 2015. Objective: We investigated the outbreak by time, place, person, and clinical symptoms. Methods: We performed a cross-sectional study. We defined a case as any resident of Heballi Agasi who had fever and rash, with or without lymphadenopathy, arthralgia, conjunctivitis, coryza, and cough, after December 15, 2014. We collected sociodemographic details and clinical symptoms of patients. We collected 5 serum samples and sent them to the National Measles Laboratory, Bangalore. We tested for measles and rubella antibodies. We drew an epidemic curve and a spot map. We computed mean age of cases, and we calculated attack rates by mean age and gender. We calculated proportions to describe clinical symptoms, and we interviewed stakeholders regarding rubella vaccination. We continued surveillance until March 2015. Results: The population of Heballi Agasi was 1,458. We identified 15 rubella cases (9 girls and 6 boys). The outbreak lasted between December 10, 2014, and February 21, 2015, with a peak on January 16, 2015. The overall attack rate was 1% (15 of 1,458). The mean age of the cases was 6 years (range, 1–23). The attack rate was high (7.7%) among those aged 1–6 years (11 of 143). The attack rate among those aged >6 years was 0.3% (4 of 1,315). In addition to fever and rash, 93% of cases (14 of 15) had coryza, 47% had cough (7 of 15), and 40% had conjunctivitis (6 of 15). Lymphadenopathy was present in only 1 case (1 of 15), and arthralgia was absent among all 15 cases. There was no death among the cases. All 5 sera were positive for rubella and negative for measles. Rubella vaccination was not given for any of the cases because no rubella vaccination is provided in the routine immunization program. Conclusions: There was a rubella outbreak in Heballi Agasi ward. Children aged 1–6 years were most affected. We recommend rubella vaccination in the routine immunization.Funding: NoneDisclosures: None

Purpose The aim of this article is to examine the association between industry payments to ophthalmologists and scholarly impact. Design Retrospective cross-sectional study. Methods All ophthalmology faculty at United States accredited ophthalmology residency programs were included in this study. The main exposure was industry payments to ophthalmologists in 2016, as reported in the Centers for Medicare and Medicaid Services Open Payments Database. The primary outcome was Hirsch index (H-index), a measure of scholarly impact. Results Among 1,653 academic ophthalmologists in our study, 1,225 (74%) received industry payments in 2016. We did not observe a difference between the mean H-index of ophthalmologists receiving any industry payments versus those not receiving any payments (p = 0.68). In analysis including only ophthalmologists who received industry payments, H-index differed significantly by payment amount: 12.6 for ophthalmologists receiving less than $100, 12.2 for those receiving $100 to 1,000, 18.8 for those receiving $1,000 to 10,000, 21.3 for those receiving $10,000 to 100,000, and 29.4 for those receiving greater than $100,000 (p < 0.001). Within each academic rank and gender, industry payments greater than $1,000 were associated with a higher H-index (p < 0.05). Conclusions Although our analysis cannot prove causality, we observed a significant association between industry payments and scholarly impact among academic ophthalmologists, even after adjusting for gender, academic rank, and subspecialty. Prospective studies should further evaluate this relationship.
