Oral lesions of systemic lupus erythematosus: A collaborative Latin American study.

BACKGROUND: Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease that may affect the oral mucosa. The variable spectrum of oral lesions observed in SLE can pose challenges in diagnosis, particularly when the lesions occur in isolation. The aim of this study was to describe the oral lesions occurring in patients with SLE from Latin America. METHODS: This collaborative record-based study involving 11 oral and maxillofacial pathology and medicine services across Venezuela, Argentina, Chile, Brazil, and Mexico describes the clinicopathological profile of SLE-related oral lesions. RESULTS: Seventy patients with SLE and oral lesions were included in the study. The majority were females (75.7%; female/male ratio: 3.1:1) and white (62.1%), with a mean age of 38.4 years (range: 11-77 years). The most common site of oral lesions was the hard/soft palate (32.0%). Clinically, oral lesions predominantly presented as ulcers (26.6%), erosions (26.6%), and white lesions (23.4%). Isolated oral lesions occurred in 65.2% of individuals, while cutaneous manifestations occurred in 80.3%. The main clinical diagnostic hypothesis in 71.4% of cases was an immune-mediated disease. Oral biopsies followed by histopathological analysis were performed in 50 cases. CONCLUSION: Oral lesions of SLE exhibit a variety of clinical and histopathological features. A key point in diagnosis is that unusual oral changes without an obvious local cause may indicate a possible systemic condition presenting with oral lesions. A multidisciplinary approach, which includes regular oral examination, is warranted to identify oral lesions and provide treatment.

Oral squamous cell carcinomas and oral potentially malignant disorders: A Latin American study.

OBJECTIVE: To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. METHODS: A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential-OSCC versus OSCC-de novo (OSCC-dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t-test, and qualitative variables with chi-square. RESULTS: In total, 2705 OSCC were included with a mean age of 62.8 years old. 55.8% were men. 53.75% of the patients were smokers and 38% were common drinkers. The lateral tongue border was the most affected site (24.65%). There were regional variations in OPMD, being leukoplakia the most frequent. Of the overall 2705 OSCC cases, 81.4% corresponded to OSCC-dn, while s-OSCC were 18.6%. Regarding lip vermillion SCC, 35.7% corresponded to de novo lip SCC and 64.3% were associated with previous OPMD. CONCLUSIONS: In Latin America, OSCC-dn seems to be more frequent with regional variations of some clinical and histopathological features. Further prospective studies are needed to analyse this phenomenon.

Cáncer Oral: Conocimiento, Actitudes y Prácticas de los Odontologos de la Provincia de Salta, Argentina, 2018

RESUMEN: Según Global Cancer Observatory de la IARC, el cáncer oral en Argentina tiene una tasa de mortalidad de 1,1 por 100.00 habitantes para 2020. La mayoría de los casos se diagnostican en etapas tardías aun cuando la detección temprana y el control de los factores de riesgo son las herramientas más eficaces para reducir la alta letalidad de esta enfermedad. Se desconoce el nivel de conocimientos, actitudes y prácticas de los odontólogos acerca de la prevención del cáncer oral en Argentina. Evaluar a través de un cuestionario, los conocimientos, actitudes y prácticas sobre el cáncer oral en la provincia de Salta, Argentina. En una muestra a conveniencia de 76 odontólogos que ejercían su profesión y que asistían a un evento de la colegiatura odontológica provincial, se aplicó una encuesta confidencial sobre conocimientos, actitudes y prácticas sobre la prevención del cáncer oral. Se analizó la encuesta a partir de estadística descriptiva e inferen cial. Los odontólogos tienen conocimiento sobre los factores de riesgo del cáncer oral, tales como consumo de tabaco (88,2 %), presencia de lesiones potencialmente malignas (84,2 %), consumo de alcohol, pero también sobre tipos de lesiones premalignas (88,2 %) y principal localización del cáncer oral (84,2 %). Las actitudes dependen de "tener una especialidad en el campo odontológico" y de "haber tomado un curso formal en los últimos 12 meses" (c2 = 13,512, GL= 4, p=0,009). Las prácticas dependen de "haber tomado un curso formal en los últimos 12 meses", de la "creencia de que el profesional está adecuadamente preparado para realizar un examen para cáncer oral", y el "tipo de práctica profesional" (c2 = 14,078, GL=7, p=0,034). Este estudio reveló que es necesario fortalecer los conocimiento, actitudes y prácticas de los odontólogos de la Provincia de Salta en Argentina frente a la prevención del cáncer oral, esto con el propósito de diseñar estrategias de salud pública realmente efectivas, que además no solo deben ser ejecutadas por la autoridad sanitaria, sino que deben ser examinadas por las escuelas de Odontología.

ABSTRACT: According to Global Cancer Observatory of the IARC, oral cancer in Argentina has a mortality rate of 1.1 per 100,000 inhabitants for 2020. Most cases diagnosed in late stages even when early detection and control of risk factors are the most effective tools to reduce the high lethality of this disease. The level of knowledge, attitudes and practices of dentists regarding oral cancer prevention in Argentina is unknown. To evaluate, through a questionnaire, the knowledge, attitudes and practices about oral cancer in the province of Salta, Argentina. In a convenience sample of 76 dentists who practiced their profession and who attended an event of the provincial dental association, a confidential survey applied on knowledge, attitudes and practices on the prevention of oral cancer. The survey analyzed based on descriptive and inferential statistics. Dentists are aware of risk factors for oral cancer, such as tobacco use (88.2 %), presence of potentially malignant lesions (84.2 %), alcohol consumption, but also about types of premalignant lesions. (88.2 %) and main location of oral cancer (84.2 %). Attitudes depend on "having a specialty in the dental field" and "having taken a formal course in the last 12 months" (c2 = 13.512, DF= 4, p=0.009). Practices depend on "having taken a formal course in the last 12 months", on the "belief that the professional is adequately prepared to perform an examination for oral cancer", and the "type of professional practice" (c2 = 14.078, DF=7, p=0.034). This study revealed that it is necessary to strengthen the knowledge, attitudes and practices of dentists in the Province of Salta in Argentina regarding the prevention of oral cancer, this with the purpose of designing really effective public health strategies, which also not only must be executed by the health authority but must be examined by dental schools.

Acquired oral syphilis: A multicenter study of 339 patients from South America.

OBJECTIVE: To report the clinicopathologic features of acquired oral syphilis cases in South American countries. MATERIALS AND METHODS: Clinical data were retrospectively collected from the records of 18 oral diagnostic services in Argentina, Brazil, Chile, Colombia, Venezuela, Uruguay, and Peru. Serologies of nontreponemal and treponemal tests were used for diagnosis. RESULTS: The series comprised 339 cases of acquired oral syphilis. Secondary syphilis ranked as the most common stage (86.7%). Lesions were more frequent among males (58.0%) and young adults with a mean age of 33.3 years. Individuals aged 20-29 years were most affected (35.3%). The most commonly involved sites were the tongue (31.6%), lip/labial commissure (25.1%), and hard/soft palate (20.4%). Clinically, acquired oral syphilis usually presented as mucous patches (28.4%), papules (25.7%), and ulcers (18.1%). Skin manifestations occurred in 67.7% of individuals, while lymphadenopathy and fever were observed in 61.3% and 11.6% of all subjects, respectively. Most patients were treated with the benzathine penicillin G antibiotic. CONCLUSION: This report validates the spread of acquired oral syphilis infection among young adults in South America. Our directives include accessible diagnostic tools for proper disease screening, surveillance, and counselling of affected individuals, especially in low- and middle-income countries.
