Metástase oral de adenocarcinoma de cólon: relato de caso / Oral metastasis of colon adenocarcinoma: case report

Introdução: as lesões metastáticas em boca são raras e representam menos de 1% de todas as neoplasias malignas. A mandíbula é a região mais afetada e, os tecidos moles, menos comumente, sendo a gengiva e a língua os sítios mais acometidos. Objetivo: relatar um caso clínico de um paciente portador de adenocarcinoma de cólon avançado sob cuidados paliativos, e que apresentou uma lesão metastática bucal. Método: relado de caso. Resultado e Discussão: O diagnóstico precoce de lesões metastáticas bucais é bastante desafiador para o cirurgião-dentista, uma vez que essas lesões podem manifestar-se clinicamente como lesões reacionais ou neoplasias benignas, que podem dificultar o diagnóstico precoce e seu imediato tratamento. Ressaltamos que o exame físico da boca deve ser realizado em pacientes oncológicos, que apresentam metástases em outros órgãos, no intuito de investigar a existência de lesões bucais e proporcionar um diagnóstico precoce, que possibilite melhor chance de tratamento e reabilitação mais favorável, quando o prognóstico do câncer é bom. Conclusão: nos casos avançados, o tratamento paliativo deve ser realizado para que haja melhor qualidade de vida ao paciente.

Introduction: metastatic lesions in the mouth are rare and account for less than 1% of all malignancies. The jaw is the most affected region, and the soft tissues are less commonly, with the gingiva and tongue being the most affected sites. Objective: the objective of this study is to report a case of a patient with advanced colon adenocarcinoma under palliative care and who presented with an oral metastatic lesion. Method: it is proposed a standard vase report. Result and Discussion: early diagnosis of oral metastatic lesions is quite challenging for the dental surgeon, since these lesions may manifest clinically as reactional lesions or benign neoplasms, which may make early diagnosis and immediate treatment. We emphasize that the physical examination of the mouth should be performed in cancer patients, who have metastases in other organs, in order to investigate the presence of oral lesions and provide an early diagnosis, which allows a better chance of treatment and more favorable rehabilitation, when the prognosis of cancer is good. Conclusion: in advanced cases, palliative treatment should be performed in order to have a better quality of life for the patient.

Especies de Candida en pacientes VIH/SIDA con candidiasis orofaringea / Candida species in HIV/AIDS patients with oropharygeal candidiasis

La infección por Candida a nivel orofaríngeo, es la infección oportunista más frecuente en pacientes VIH/SIDA,al menos un episodio de candidiasis desarrollan estos pacientes en el curso de la evolución de su enfermedad. La determinación de especies de Candida, permite orientar de manera adecuada el tratamiento. El objetivo de la presente investigación fue identificar las especies de Candida aisladas en 60 pacientes VIH/SIDA con candidiasis orofaríngea, asistentes al Centro de Atención Integral - Enfermedades de Transmisión sexual y SIDA. (CAI/ETS/SIDA) en el período Junio-Diciembre 2006. Se les tomó muestra de raspado lingual y se cultivó en Agar Sabouraud-Cloranfenicol para el aislamiento primario. La identificación de las especies de Candida, se realizó por medio de la producción de: tubos germinativos, clamidosporas en Agar - Maiz Tween 80 según la técnica de Dalmau y el sistema Api 20CAUX bioMérieux. Se observó en estos pacientes predominio del sexo masculino (48) 80%, con edades comprendidas entre 20 y 60 años Se aislaron en orden de frecuencia C. albicans 66,6 % (40), C. tropicalis 13,33 % (8), C. glabrata 11,6 % (7), C. parapsilosis 6,66 % (4), C. krusei, 66% (1). Se recomienda la identificación de especies de Candida como prueba de rutina en pacientes VIH/SIDA

Oral candidiasis has been recognized as the most common opportunistic infection in HIV/AIDS patients. These patients present at least one episode of oral candidiasis in the development of the disease. The isolation of Candida species has let to apply the correct treatment to these patients. The purpose of the investigation was to identify the species of isolated Candida in 60 HIV/AIDS patients with oropharyngeal candidiasis that assist to the Center of Integral Attention of Sexual Transmission Diseases and AIDS from June to December 2006. The samples were taken from the mucosal surface of the tongue and laid in Sabouraud-Cloramphenicol agar for the first isolation; the identification of Candida species were done by forming germ tubes, Terminal Chlamydospore formation on corn meal agar with Tween-80 following the Dalmau technique and the Api 20CAUX bioMerieux. Most of the patients were males (48) 80% and age ranging 20 to 60 years old. The most frequent yeast specie found was : C, albicans 66,6 % (40) , C. tropicalis 13,33 % (8) , C. glabrata 11,6 % (7) ,C. parapsilosis 6,66 % (4) , C. krusei 1,66% (1). It is recommended the isolation of the species as a rutin test in the HIV/AIDS patients

Efecto antibacteriano de 5 antisépticos de uso en cavidad bucal / 5 antibacterial use antiseptic mouth

La resistencia bacteriana a sustancias químicas es un problema de salud pública. Un Ejemplo es el Staphylococcus aureus. La presión selectiva de los antisépticos ha generado una respuesta de los microorganismos a evadir la acción de algunos agentes químicos. El propósito del estudio fue determinar el efecto antibacteriano ejercido por 5 antisépticos usados en cavidad bucal, en contra de las bacterias S. aureus y E. coli. En frascos se depositaron recortes de papel filtro Wathman Número 2, se taparon y esterilizaron, se les agregó el antiséptico a probar, y se dejó embeber. Por otro lado se subcultivaron en caldo BHI cepas de E. coli y S. aureus durante 18 horas, a 37° C, de aquí se volvieron a resembrar a manera de antibiograma en cajas de agar soya tripticasa, luego se depositaron equitativamente 4 recortes embebidos con el antiséptico, se incubaron por 24 hrs. a 37° C., se sacaron los cultivos, se midieron los halos de inhibición bacteriana, se sacó el halo promedio para cada antiséptico siendo éste el reporte final. De los 5 antisépticos estudiados, presentaron de mayor a menor halo de inhibición: 1.-Peróxido de Hidrógeno al 3.18%. 2.-Hipoclorito de sodio al 1.25%., 3.-Hidróxido de calcio al 5% 4.-Clorhexidina al 0.12%., 5.- Isodine bucofaríngeo al 0.8%. Dos antisépticos presentaron un efecto antibacteriano inferior a lo descrito bibliográficamente. Por lo anterior se sugiere informarse, de manera actualizada sobre: concentración, mecanismo de acción, tiempo de exposición, ventajas y desventajas de los antisépticos

The bacterium resistance to chemical substances, is a public health problem of public health. An example, is the Staphylococcus aureus. The selective pressure of antiseptics has generate an answer in the microorganisms, to evade the action for some chemical agents. The purpose of the study was to determine the antibacterium effect done by the antiseptics used in bucal cavity, against S. aureus and E. coli bacterium. In deposit bottles cuts of filter paper, covered and sterilized, then add the antiseptic that was testing and left them to wet. In the other side has subcultivate in soup BHI E. coli and S. aureus incubated about 18 hrs. at 37ºC., after this has sowed again in a antibiogram way in dishes soy tripticase agar. After that deposit ecually 4 cuts of wet filter paper with antiseptic, incubated 24 hrs. at 37ºC., take out the cultives, measure the halos of bacterium inhibition. Was efectuated in 3 dishes take the average halos inhibition for each antiseptic being this the final report. From the 5 studied antiseptics, presented from biggest to smallest inhibition halo:1. - Hydrogen peroxide to 3.18%. 2. - Sodium hipoclorite at 1.25%. 3. - Calcium hydroxide to 5%. 4. - Clorhexidina gluconate at 0.12%, 5. - Isodine bucofaringeo at 0.8%. 2 antiseptics presented antibacterium effect lower to the described bibliographically, to the mentioned before is suggested to get informed and promote information, actualized about: concentration, action mechanism, exposition time, advantages, disadvantages of the antiseptics
