Mechanical Irritation

Objective. Oral mucosa could host many lesions originated by chronic mechanical irritation (CMI) from teeth or dentures, and it has been proposed as risk factor for oral cancer. Nevertheless, the features of CMI factors in oral cancer and other lesions are not assessed. The aim of this study is to describe CMI features regarding type (dental, prosthetic, and/or functional), localization, and time span.Materials and Methods. Three groups were studied in this cross-sectional study: Oral Cancer (OC); Chronic Traumatic Ulcer (CTU); and Benign Irritative Mechanical Lesions (BIML). All sources of mechanical irritation were included: dental, prosthetic, and functional.Results. 285 patients (176 females, 109 males) were studied: OC = 38, CTU = 44, and BIML = 203. The most frequent CMI factor was dental, followed by functional and prosthetic in all groups; 76.5% (n=218) presented functional factors. Buccal mucosa (45%) and tongue (42%) were the most affected sites. Time of action of CMI displayed statistically significant differences between BIML, CTU, and OC groups, with a mean of 21, 33, and 49 months, respectively.Conclusions. CMI should be properly recorded with as much detail as alcohol and tobacco consumption. CMI associated lesions are produced by dental or prosthetic factors, usually in relation to functional factors, involving mainly tongue and buccal mucosa.

Oral cancer is the most common form of carcinoma of oral cavity and ranks as the 12th most common cancer in the world. Oral cancer is one of the major social & health problems in India and Indian subcontinent countries. Tobacco use in different forms is the main etiological factor for oral carcinoma. (i) To define relations of oral cancer with respect to gender, age group, socioeconomic status and risk habits; (ii) To observe the distribution of affected oral cavity sites and observe the clinical profile in oral cancer patients. A cross-sectional study of 340 oral cancer patients from January 2019 to December 2019 was carried out in Department of oncology & radiotherapy, JA Group of hospital, G. R. Medical Gwalior, Madhya Pradesh India. Details of patient's sex, age, tobacco habit and site of cancer and status were noted. Data were analyzed by probability of patient with risk factors and chi-squire (χ) test. The prevalence of oral cancer was significantly (p < 0.001) higher in males (91.5.9%) than females (8.5%). In both the sexes, most affected sites were the buccal mucosa and gingivo-buccal sulcus. However, the consuming form of tobacco was found to be significantly associated with oral cancer, in both sex. The study revealed that oral cancer is more common in men, probably due to habit of large tobacco consumption.

PurposeThe purpose of this paper is to assess the levels of awareness and knowledge about oral cancer, its causes and or risk factors among Ugandan patients seeking oral healthcare.Design/methodology/approachThis was a cross-sectional study on adult patients who attended a free dental camp. An assistant-administered questionnaire either in English or Luganda was provided to every even-numbered registered adult who consented to participate in the study. Information on demographics and known risk factors for oral cancer were captured. The two knowledge questions on oral cancers were scored by adding up all the correctly identified causes, non-causes and risk factors then scored out of the total. Data analysis was done by calculating proportions, Student’s’t-tests andχ2tests with significantp-value set at 0.05.FindingsThe results showed a low level of awareness/knowledge about oral cancer in studied population. In total, 60 percent and less than 50 percent of respondents identified smoking and alcohol use as risk factors for oral cancer, respectively. Majority of respondents (88.8 percent) would seek help from medical personnel if diagnosed with oral cancer. Screening for cancer was low despite awareness and knowledge that it improves the chances of successful treatment.Research limitations/implicationsEmphasis on risk factors including alcohol use in public health messages, use of mass media, religious and community leaders to disseminate messages to the communities and further research were recommended.Practical implicationsWe need to emphasize the role of alcohol in oral cancer causation just as we do for tobacco consumption.Originality/valueNo study has been conducted in Uganda on the level of awareness yet the incidence of the disease and use of high-risk products are rising.

Level Of Knowledge

Introduction and Objective: To evaluate the level of knowledge about oral cancer of students attending public school in one city of Santa Catarina (Brasil). Material and methods: A descriptive cross-sectional study, using primary data collection. Students of last year of elementary school and first year of high school, enrolled in public schools in the city of Itajaí (SC), in 2012, were the target population. The non-probability sample was obtained by convenience. Data were collected through a self-administered questionnaire structured with 13 questions divided into three fields. The level of knowledge was made based on pre-established scores. Results: 1149 instruments were analyzed (80.8% of the target population). The average age of the group was 15.5 years and 54.5% were female. The majority (78%) never had received information about oral cancer. Only 27.9% had cognizance about self-examination of the oral cavity. With regard to knowledge, 87.5% classified as unsatisfactory. For most issues the cognitive field did not identify a significant correlation between knowledge and the variables gender and education. When asked if they would like to participate in educational and preventive activitiesabout oral cancer and other issues related to health, 72.6% expressed interest. Conclusion: The group did not have adequate knowledge on the subject of oral cancer. Facing this reality, and the positive attitude of respondents, the researchers designed and offered an educational program to the research subjects.

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.

BACKGROUND Brain tumours represents 1.7 % of all cancers and contributes 1.8 % of all cancer deaths. Of all the brain tumours, 80 % are supratentorial.1 Magnetic resonance imaging (MRI) is an important modality, having higher sensitivity for detecting intracranial pathology. Multiplanar imaging is possible with MRI which helps in detection, localization and characterization of the lesion. MRI examination has helped in early diagnosis, accurate localization of the tumour, with prompt initiation of appropriate medical or surgical therapy. Recent advances like magnetic resonance (MR) spectroscopy, MR fluoroscopy with stereotactic guided biopsy have revolutionized the role of MRI in study of intracranial tumours. METHODS A cross sectional study of 75 patients was done by Siemens Essenza 1.5T MRI from June 2018 to June 2020 using dedicated head coil. RESULTS In our study, most of the patients were between 31 - 60 years of age (39 % of all patients) with the largest group between 31 - 40 years (20 % of all patients). Out of 75 cases of supratentorial neoplasms, 47 (72 %) were intra-axial lesions, 15 (23 %) were extra-axial lesions and 3 (5 %) were intra ventricular lesions. In this study, 69 % of the lesions were solitary and 31 % were multiple. Most of patients (89 %) showed some enhancement, most common being heterogeneous/inhomogeneous enhancement. Commonest type of supratentorial neoplasms were metastases comprising 29 % of this study. CONCLUSIONS Magnetic resonance imaging is an important modality, having higher sensitivity for detecting intracranial pathology. Multiplanar imaging is possible with MRI which helps in early detection, localization and characterization of the lesion. Metastasis is the most common supratentorial tumour in this study followed by meningioma. Intra-axial tumours are more common than extra-axial tumours in this study.

To determine the association between tobacco consumption and self-reported visual impairment. We performed a cross-sectional study based on an original cohort study. A non-probabilistic sampling was performed to invite 413 patients of 60 years or more from 11 high-altitude Andean communities (altitude higher than 1500 m above sea level) of Peru between 2013 and 2017. Demographic data and information on tobacco consumption were collected. Associations were determined using a Poisson regression model with 95% confidence intervals (CI). Of the 413 participants, 141 (34.14%) were men and 49 (11.86%) were tobacco users. In the adjusted model, tobacco users presented a high probability of visual impairment with a prevalence ratio of 1.32 (95% CI: 1.18–1.97). We also found that having two or more comorbidities 2.19 (95% CI: 1.53–3.15), receiving health assistance in a pharmacy 3.75 (95% CI: 1.97–7.16), and coffee consumption 1.67 (95% CI: 1.26–2.21) were factors significantly associated with self-reported visual impairment. We determined that in Peruvian high-altitude Andean communities, visual impairment was more frequent in individuals reporting tobacco consumption, taking alternative medicine, going directly to a drug store without primary care physician consultation, having more than one comorbidity, and coffee consumption.

Purpose. To study the clinicodemographic profile of dome-shaped maculopathy (DSM) eyes in the Indian population and characterization using spectral-domain optical coherence tomography (SD-OCT). Methods. This observational cross-sectional study included 25 eyes of 14 patients diagnosed with DSM. All eyes underwent SD-OCT for characterization of the dome profile and also to measure central macular thickness (CMT), subfoveal choroidal thickness (SFCT), and dome height (DH) and to detect the presence of subretinal fluid (SRF). Results. The mean age of patients was 48.36 ± 14.23 years (range, 28–65 years). Eleven patients had bilateral involvement. Mean axial length of all eyes was 24.25 ± 1.95 mm and mean spherical equivalent −4.23 ± 3.79 DS. Overall, 11/25 eyes (44%) had round domes, 9/25 eyes (36%) had horizontal domes, and 5/25 eyes (20%) had vertical domes, with a mean dome height at fovea of 500.54 ± 291.58 µm. Vertical domes had higher DH compared to horizontal or combined domes p = 0.02 . Six eyes (6/25, 24%) showed the presence of SRF; 60% of vertical domes had SRF, and 22.2% of horizontal domes had SRF. The eyes having SRF had significantly higher CMT p = 0.017 and DH p = 0.001 , especially in horizontal domes p = 0.023 . The eyes with thicker SFCT tended to have higher DH and poorer visual acuity. Conclusion. Indian DSM eyes may have relatively lesser amounts of myopia. Choroidal thickening may play a role in development of DSM and may also be related to development of subretinal fluid in such eyes.

Final Sample

The objective was to characterize and compare the subgingival microbiota in patients diagnosed according to the World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions 2018. For this cross-sectional study, Spanish and Colombian subjects (characterized as health/gingivitis, periodontitis in stages I-II or stages III-IV) were clinically assessed, and subgingival samples were taken and processed by culture. The comparisons among patients with periodontal status (and between countries) was made using Mann–Whitney, Kruskal–Wallis, ANOVA and chi-square tests. The final sample consisted of 167 subjects. Eikenella corrodens and Parvimonas micra were more frequently detected in health/gingivitis and Porphyromonas gingivalis in periodontitis (p < 0.05). Higher total counts were observed in Colombia (p = 0.036). In Spain, significantly higher levels of P. gingivalis and Campylobacter rectus were observed, and of Tannerella forsythia, P. micra, Prevotella intermedia, Fusobacterium nucleatum, Actinomyces odontolyticus and Capnocytophaga spp. in Colombia (p < 0.001). P. micra was more prevalent in health/gingivitis and stage I-II periodontitis in Colombia, and P. gingivalis in all periodontitis groups in Spain (p < 0.05). As conclusions, significant differences were detected in the microbiota between health/gingivitis and periodontitis, with minor differences between stages of periodontitis. Differences were also relevant between countries, with Colombia showing larger counts and variability of bacterial species.
