ABSTRACT
La PTI es una alteración hemorrágica de instalación súbdita, adquirida, que se manifiesta inicialmente con petequias, equimosis o hematomas en piel y mucosas, sangrado nasal y gingival, sin causa aparente. La mucosa bucal puede ser el sitio donde las lesiones se observen con frecuencia y por primera vez. Se reporta el caso de un paciente masculino de 28 años de edad, con manifestaciones clínicas de un cuadro purpúrico, se describen signos, síntomas, terapéutica y manejo estomatológico (AU)
PTI is a hemorrhagic alteration of sudden installation, acquired, which manifests initially with petechiae, esquimosis or bruises on skin and mucosae, nasal and gingival bleeding without apparent cause. Bucal mucosae can be the site where lesions are observed with frequency, and for the first time. The case of a male patient with 28 years of age with clinical manifestationsofpurpuric syndrome is reported, signs, symptoms, therapeutic and stomatological handling are described (AU)

Abstract Arsenic contamination in the environment and groundwater is a major global public health problem. Several researchers suggest that the toxicity of arsenic could be related to oral cancer development, usually resulting from potentially malignant lesions. During pathological processes, salivary proteins suffer modifications, which could lead to the discovery of new biomarkers. Objective To analyze the protein profile in human saliva samples from a rural population exposed to high levels of arsenic in drinking water and its association with potentially malignant lesions. Methodology This observational, analytic and cross-sectional design included 121 patients from the state of Graneros (Tucumán, Argentina). Arsenic concentration in drinking water was determined and, according to the values obtained, individuals were divided into 2 groups: exposed group and non-exposed group. Saliva samples were obtained, and total protein concentration was measured by Bradford method. Finally, Laemmli SDS-polyacrylamide gel electrophoresis was conducted to obtain the protein profile. Results Total protein concentration in saliva was lower in the exposed group than in the non-exposed group. Average areas of 20 and 42 KDa bands were significantly lower in exposed group than non-exposed group. Conclusion Chronic intake of high arsenic concentrations in drinking water produces changes in the salivary protein profile, which is associated with the presence of potentially malignant lesions.

El adenocarcinoma de células basales, también conocido como carcinoma salival basaloide, adenoma maligno de células basales, es una neoplasia epitelial de bajo grado, infiltrante, localmente destructivo y con tendencia a ser recidivante. Su aparición es entre la 5ª y 6ª década de vida, sin predilección por sexo. Clínicamente se manifiesta con un edema o un aumento repentino de tamaño en la zona, de consistencia firme, crecimiento lento e indoloro. El diagnóstico de certeza es a través de la histopatología; su tratamiento quirúrgico, y tiene buen pronóstico en sus estadios iniciales (AU)
Basal cells adenocarcinoma also known as salivary basaloide carcinoma basal cells malignant adenoma is a low degree, infiltrating, locally destructive and prone to be relapsing, epithelial neoplasia. It occurs between the 5th and 6th decade of life, with no predilection for sex. Clinically it manifests with an edema or sudden increased size in the area, of firm consistency, slow growth and pain-less. Its treatment is surgical and the diagnosis of certainty is histopathological with a good prognosis. The purpose of this presentation is to show the case of a 57- years-old male patient with clinical and anatomopathological diagnosis of adenocarcinoma of basal cells located in the yugal mucosa (AU)

El Cáncer Oral ocupa el sexto lugar entre los distintos tipos, y el 90% corresponde al Carcinoma de células escamosas de cavidad oral. Esta patología tiene una distribución mundial desigual. En Latinoamérica las incidencias más altas se reportan en Argentina, Sur de Brasil y Uruguay. La localización del tumor, el estadio clínico en que es diagnosticado, el tipo de tratamiento, entre otras variables, influyen en la supervivencia de los pacientes. Los distintos autores indican que en un alto porcentaje son diagnosticados en estadios avanzados lo que conlleva a una reducción evidente de la posibilidad de subsistir. Se presenta el caso clínico de un paciente sexo masculino de 75 años de edad que consulta por lesión tumoral en encía con 60 días de evolución. Se describen manifestaciones clínicas, radiológicas e histopatológicas. Se concluye en la necesidad de la detección y manejo oportuno por parte de odontólogos y médicos de ésta nosología (AU)

Las hiperplasias gingivales localizadas son lesiones muy frecuentes en cavidad bucal que corresponden a una reacción de proliferación excesiva del tejido conectivo como respuesta a un estímulo o agresión. El objetivo del presente trabajo es presentar dos casos clínicos diagnosticados y tratados en nuestra clínica, con sus estudios histopatológicos y la correlación con los posibles agentes causales.
