Impact of oral mucosa lesions on the quality of life related to oral health. An etiopathogenic study.

BACKGROUND: To assess the impact of oral mucosa lesions on quality of life related to oral health (QLROH) and additionally to establish whether the etiopathogenicy of oral lesion is associated to the degree of QLROH impact. MATERIAL AND METHODS: In this cross-sectional study performed on a non-probability sample of 247 consecutively patients attending the oral medicine and pathology clinic the Spanish version of Oral Health Impact Profile-49 questionnaire (OHIP-49-mx) was applied. Responses were recorded on Likert-type scale whose values ranged from 0 (never) to 4 (always). Values greater than the 50 percentile (median) were considered as indicative of poor quality of life. All patients were orally examined and diagnosed. In accordance to their etiopathogenicy 6 study groups were formed: 4 corresponded to MIND classification for diseases (Metabolic, Inflammatory, Neoplastic, and Development groups), with ≥2 diseases and no-lesion group. To identify possible differences of OHIP-49 values between study groups an ANOVA (one factor) parametric and a chi square tests were performed (SPSS®20.0). RESULTS: The OHIP-49-mx values were higher than the 50 percentile (established at 39) in metabolic, inflammatory, development, and ≥2 diseases groups, suggesting that this type of oral lesions negatively impact the quality of life. ≥2 diseasesgroup followed by metabolic and inflammatory diseases group (p 0.001) depicted worst quality of life. Functional limitation (p 0.003), pain, physical inability (p 0.001) and psychological disabilities dimensions exhibited greater values in all groups. CONCLUSIONS: Injured oral mucosa negatively impacts quality of life, specifically functional limitation, physical inability and psychological disabilities could lead to social isolation.To our knowledge, this is the first time that an association between QLROH and the etiopathogenicy of oral mucosal diseases is established.

In accordance to their etiopathogenicy 6 study groups were formed: 4 corresponded to MIND classification for diseases (Metabolic, Inflammatory, Neoplastic, and Development groups), with more or equal 2 diseases and no-lesion group. To identify possible differences of OHIP-49 values between study groups an ANOVA (one factor) parametric and a chi square tests were performed (SPSS(R)20.0). RESULTS: The OHIP-49-mx values were higher than the 50 percentile (established at 39) in metabolic, inflammatory, development, and more or equal 2 diseases groups, suggesting that this type of oral lesions negatively impact the quality of life. more or equal 2 diseases group followed by metabolic and inflammatory diseases group (p 0.001) depicted worst quality of life.

Estandarización en la observación y clasificación de lesiones epiteliales premalignas y malignas / Standardization in the observation and classification of premalignant and malignant epithelial lesions

Los criterios histológicos para determinar el grado de displasia, la clasificación de Broders y el frente de invasión tumoral (FIT) son parámetros subjetivos no cuantificables que pueden indicar el grado de evolución de displasias y carcinomas. Un factor importante a considerar durante la valoración histológica, es la variabilidad del diagnóstico entre patólogos. El objetivo es estandarizar los criterios y determinar la variabilidad intra e inter observador en el diagnóstico de displasias y COCE. Se seleccionaron y estandarizaron los criterios morfológicos para el diagnóstico y se revisaron los casos seleccionados aleatoriamente por tres patólogos bucales (30 displasias y 30 carcinomas) del Laboratorio de Patología Clínica y Experimental de la DEPeI de la FO, UNAM. Cada patólogo analizó y registró los parámetros establecidos para displasia, COCE y FIT en 2 ocasiones. Se aplicó el test Kappa para valorar la concordancia intra e inter observador. El Observador 1 v/s el 2 obtuvo una concordancia para COCE de 0,75 y en displasias de 0,60 e intraobservador de 0,90. El observador 2 v/s el 3 presentó una concordancia para COCE de 0,75 y en displasias de 0,59 e intraobservador de 0,91. El Observador 3 Vs el 1 tuvo una concordancia para COCE de 0,77, y en displasias de 0,59 e intraobservador de 0,92. La concordancia intraobservador e interobservador en COCE fue de buena a excelente, pero en displasias fue aceptable confirmando que su evaluación presenta mayor grado de dificultad. Con una adecuada estandarización se puede obtener una buena concordancia entre patólogos.

In the histological criteria for determining the degree of dysplasia, the Broders classification and the front of tumor invasion (FTI) are unquantifiable subjective parameters that may indicate the degree of development of carcinomas. An important factor to consider during the histological evaluation is the variability in the diagnosis of pathologists. The objective to standardize criteria and determine the intra and inter-observer variability in the diagnosis of dysplasias and OSCC. We selected and standardized morphological criteria for the diagnosis, and the cases were reviewed randomly by three oral pathologists (30 dysplasias and 30 carcinomas) from the Laboratory of Clinical and Experimental Pathology of the FO DEPeI, UNAM. Each pathologist analyzed and recorded the parameters for dysplasia and OSCC FIT on two occasions. Kappa test was applied to assess intra and inter-observer agreement. Observer 1 v/s 2 match for OSCC was 0.75, 0.60 for dysplasias and intra observer 0.90. Observer 2 v/s 3 presented a concordance of 0.75 for OSCC, 0.59 for dysplasias and intra-observer 0.91. Observer 3 v/s observer 1 for OSCC was 0.77, 0.59 for dysplasias and intra-observer 0.92. Intra observer and inter-observer concordance in OSCC were good or excellent, but in dysplasia was acceptable, confirming that its assessment showed the greatest difficulty with proper standardization we can obtain a better consensus between pathologists.
