Increased nuclear β-catenin expression in oral potentially malignant lesions: a marker of epithelial dysplasia
Background: Deregulation of β-catenin is associated with malignant transformation; however, its relationship with potentially malignant and malignant oral processes is not fully understood. The aim of this study was to determine and compare the nuclear β-catenin expression in oral dysplasia and oral squamous cell carcinoma (OSCC). Material and Methods: Cross sectional study. Immunodetection of β-catenin was performed on 72 samples, with the following distribution: 21 mild dysplasia, 12 moderate dysplasia, severe dysplasia 3, 36 OSCC including 19 well differentiated, 15 moderately differentiated and 2 poorly differentiated. Through microscopic observation the number of positive cells per 100…
Oral metastasis of renal cell carcinoma : presentation of a case
The oral cavity constitutes a site of low prevalence for metastasis of malignant tumors. Nevertheless, it has a high prevalence for metastasis of renal origin. Besides the kidneys, there are other primary sites with high prevalence of metastasis to the oral mucosa, such as the lungs, skin and breasts. Metastasis is common in patients with a background of treated renal tumors, thereby, it is proper to determine the possibility of oral metastasis as part of the protocol of attention. However, it constitutes a diagnostic challenge when it presents in patients with no renal antecedents. It is in this type of patients that the diagnosis of carcinoma is achieved by means of a metastasis. Survival…
Asociación entre alteraciones psicológicas y la presencia de Liquen plano oral, Síndrome boca urente y Estomatitis aftosa recividante
OBJETIVO: El propósito de este estudio fue determinar la relación existente entre el Liquen Plano Oral (LPO),Estomatitis Aftosa Recividante (EAR), Síndrome de Boca Urente (SBU) y las alteraciones psicológicas del paciente, tales como el estrés, la ansiedad y la depresión. DISEÑO DEL ESTUDIO : Fueron estudiados 18 pacientes con EAR , 9 pacientes con LPO y 7 pacientes con SBU, que presentaron la lesión en el momento del examen, más un grupo control de 20 pacientes sanos. Ambos grupos fueron extraídos de centros hospitalarios y docentes, donde el diagnóstico clínico fue realizado por un equipo de patólogos orales. A los pacientes se les aplicó dos instrumentos de medición del estado psicológic…
Salivary gland dysfunction markers in type 2 diabetes mellitus patients
Background: Diabetes mellitus (DM) is a chronic disease of the carbohydrate metabolism that, when not rigorously controlled, compromises systemic and organ integrity, thereby causing renal diseases, blindness, neuropathy, arteriosclerosis, infections, and glandular dysfunction, including the salivary glands. The aim of this study was to determine the relationship between the qualitative and quantitative parameters of salivary alteration, which are indicators of salivary gland dysfunction, and the level of metabolic control of type 2 diabetes patients. Material and Methods: A convenience sample of 74 voluntary patients with type 2 DM was selected, each of whom donated a sample of unstimulate…
