RESUMO

La mucosa bucal ha sido utilizada en Medicina como órgano blanco para inducir moléculas farmacológicas, inmunomoduladoras y vacunas. Tales prácticas se han basado en "investigaciones científicas avaladas por sus resultados" y en la "Medicina basada en la evidencia". Hoy en día ambas terapias se aplican como prácticas correctas. Sin embargo, es posible establecer la pregunta siguiente: ¿Son conocidas, previamente, las características específicas de la mucosa oral y sus variantes? Para obtener una respuesta satisfactoria, se presenta una revisión sistemática de calidad, consultando en la bibliografía las cualidades específicas de la mucosa bucal.(AU)


Oral mucosa have been used in Medicine as a tarjet organ to induce pharmacological, immuno modulated molecules and vaccines .Such practices have been based on the scientific investigations results, and by "Evidence Based Medicine (EBM)". Today both therapies are applied as corrected practice. However, it´s possible to establish the following question: ¿There are known, previously, the specific characteristics of oral mucosa and its variants which could benefit or interfere the results? In order to identify relevant studies about this request, it´s present a systematic review of quality, consulting .specific bibliography.(AU)

RESUMO

Introducción: Los linfomas No- Hodgkin presentan características propias cuando se asocian a la infección por el Virus de la Inmunodeficiencia Humana. La cavidad bucal es una de las localizaciones a tener en cuenta en pacientes con Sida (LNHORS) Si bien se registran casos en los primeros estadios de la infección, el diagnóstico previo diferencial estomatológico y su seguimiento no se realizan en nuestro medio con la frecuencia que esta enfermedad requiere. En los pacientes VIH positivos, las características generales están relacionadas con la edad de los pacientes, el estado de base inmunológico de la infección, la adherencia a los tratamientos, una historia de más de 35 años de drogadicción intravenosa y el tipo de linfoma. El presente trabajo tiene dos objetivos: 1) Presentar una actualización del tema ya que en los últimos años se han investigado los diferentes tipos y subtipos histológicos, su estratificación y tratamientos en forma intensa y 2) presentar un caso clínico de Linfoma no Hodgkin con localización en la cavidad bucal de evolución no frecuente. Desarrollo: Una paciente de 34 años de edad con una masa tumoral en el hueso maxilar mucosa gingival y paladar duro y blando. La lesión estaba ulcerada en la primera consulta y hacía protrusión a través de la cavidad bucal. Resultados: se realizaron estudios sistémicos, biopsias de las lesiones orales, estudio histológico y marcación inmunohistoquímica,, búsqueda por diagnóstico por imágenes de otras manifestaciones y localizaciones de linfomas. Fueron establecidos tratamientos, seguimiento y evolución. Conclusiones: Un diagnóstico eficiente y temprano de los pacientes con LNHORS por un equipo de salud, puede incrementar las sobrevidas, en un marco, donde pueda ser posible la reconstitución de la función inmunológica y puedan ser aplicados los nuevos regímenes de infusión contínua con quimioterápicos (AU)


Introduction: Non-Hodgkin Lymphoma presents their own characteristics when it is associated with the human immunodeficiency virus syndrome (HIV). Oral cavity is one localization in Aids patients (LNHOES) and its manifestations are registered on the first state of HIV infection. But oral differential diagnoses is not so frequent as this disease needs, in our environment. On HIV patients general characteristics are related to the age of patients, immunological status, treatment compliance, intravenous drug addictions for more of 35 years and lymphoma type. The present work has two objectives: 1) To present this subject in order to actualize epidemiological news, histological types and subtypes classification, illness stratification and advances on therapy., because it has been, in recent years, intensive researches about it. 2) To report a clinic HIV+ case with NHL, with an infrequent evolution. A female patient of 34 years old, with a tumor mass on maxilla bone, gingival mucosa and hart and soft palate. Lesion was ulcerated at the first consultation and hat protrude trough the mouth. Results considered different systemic studies, biopsies of the oral lesions, histological study and immuno histochemical marcation, and searching of other lymphoma´s manifestations and locations by scan´s studies. Treatments, follow up and evolution were assessed Conclusions: An efficient and early diagnostic of ARONHL by a health team work, can increase longer survival for this patients, in an scene, where it can be possible the reconstitution of immunological function and where it could be applied Continous Infusion Chemotherapy new regimens (AU)

RESUMO

Estableciendo las bases del proceso Enseñanza/Aprendizaje de la Estomatología para alumnos del último nivel de la currícula de Odontología, y en especial de la Asignatura Patología y Clínica Estomatológica, se ha diseñado este estudio. El mismo se ha llevado a cabo teniendo en cuenta los siguientes Objetivos: 1) La observación del desempeño de los estudiantes en un hospital público, en donde han realizado su trabajo en terreno. 2) Un relevamiento de las lesiones y enfermedades que se han presentado con la observación y guía por el personal docente y la resolución de los casos clínicos. Material y Métodos: los alumnos del nivel quinto de la Asignatura de Patología y Clínica Estomatológica de la Facultad de Odontología de la Plata, año tras año han sido citados, por comisiones pequeñas (no más de 7alumnos por cada una) con el fin de observar y participar de la tarea hospitalaria que realiza un equipo docente de Estomatología dentro del funcionamiento del Servicio de Odontología de un Hospital de Agudos. Se tomaron los datos correspondientes a un tiempo estimado en horas de 1.800 horas paciente/docente-alumno. De 495 pacientes fueron evaluados los datos de edad, sexo, ocupación, estado civil, hábitos y factores ambientales. Se registraron los datos correspondientes a las lesiones y enfermedades y se realizó el análisis estadístico de los mismos. Resultados: 1) Los alumnos demostraron interés y entusiasmo al concurrir a la Unidad Hospitalaria. Este resultado se midió por la cantidad de alumnos que solicitaron poder concurrir al Hospital fuera de las horas de clases en forma voluntaria: 40%. 2) Del estudio del relevo de datos, las micosis superficiales fueron las más prevalentes seguidas por aftas, líquenes atípicos y carcinomas a células escamosas. Conclusiones: 1) Se observa que el Hospital docente asistencial pareciera brindar al mecanismo de Enseñanza/Aprendizaje, la posibilidad de insertar al alumno en la realidad de la salud pública del medio ambiente al cual pertenece. 2) Las demás especialidades, integradas al Servicio de Odontología/Estomatología, permitirían una acción en conjunto del equipo sanitario, por un fenómeno de retroalimentación. 3) Coincidiendo con otros datos de diversos Servicios Asistenciales y otras Facultades del país, la Candidiasis oral resultó la lesión más frecuentemente observada. 4) La incidencia de Cáncer bucal nos lleva a insistir sobre su diagnóstico temprano y la importancia del reconocimiento de las enfermedades precancerosa y establecer estrategias contra el hábito del tabaquismo, en nuestro medio de referencia (AU)


This study was designed in order to establish basement of Teaching/Learning process in Stomatology, for students of the last step of Curricula in Odontology and, very specially for Patology and Stomatological Clinic’ attenden. Objectives were: 1) Observation of students behaviour in a public hospital, were it takes place, their «work in situ». 2) To stand out diagnosticated lesions and diseases with the guide of experimental teachers and, resolution of clinic cases. Material and methods: Students of the last level of Patology and Clinical Stomatology Asignature, of the Odontology Faculty of La Plata City, year by year were sending in small groups (no more than seven students each), to a Public Hospital, to Odontology Unit, to participate in an equipment composed by Docents of the Faculty that works in this hospitalry Service and in relationship with other medical units of the same Hospital. For this study, data was assesed taking 1.800 hours/patient. 495 patients were evaluated and sex, age, civil state, ocupation, habits and factors of the enviroment were tabulated. Screaning of lesions and diseases were made and an statistic analyse was performed. Results: 1) Students demostrated, most of the time, really interesting and entusiassm. This result was calculated in a frequence of 40% of them, who wanted to state longer overthere and to come back, out of their own study classes and obligations. 2) From lesions and diseases data study, superficial mycosis was the most prevalent disease that it was founded, followed by major afthous and carcinomas of squamous cells. Conclusions: 1) Its was observed that Assistant/Docent/ Hospital educational method woul offer to Teaching/ Learning mechanism, the possibility to insert the students inside their real public health medium. 2) Other medical specialities integrated with Stomatology seems to allow a common sanitary equipment by a retronutritionary phenomem. 3) In agreement with other data of asistant services and other faculties of our country, Oral Candidiasis was the most observed disease. 4) Incidence of Oral cancer advices us to insist about its early diagnosis, the importance of pre-malignant lesions recognition and to improve strategies againts nicotinism, in our environment (AU)

RESUMO

La sífilis es una enfermedad de transmisión sexual con mayor incidencia y prevalencia mundial desde la aparición de la infección por el Virus de la Inmundeficiencia Humana Adquirida. La presentación de este caso clínico tiene por objeto 1- Describir las lesiones de un secundarismo sifilítico en una paciente adolescente con presunción de estar infectada por el VIH. 2- Señalar la evidencia que muchos pacientes con pruebas positivas para sífilis inician tratamiento pero no retiran los resultados de la serología para VIH (como en este caso), contribuyendo así a la expansión del VIH (AU)


Syphilis is a sexual transmitted disease with more incidence and prevalence in all of the world since the Acquire Human Immunodeficiency had appeared. The objectives of the report of this case are: 1-To describe lesions of secondary syphilis of an adolescent female with HIV infection presumption. 2 - To point out the evidence that many patients with positive result for syphilis begin his treatment but does not rescue the serology for HIV, (as this case) , contributing the spreading of this virus and its consequences (AU)

RESUMO

UNLABELLED: Annual incidence of condyloma acuminata has been reported to be high as 106.5 per 100.000, or about 0,1% of the entire population. In HIV+ individuals, HPV infection is even more prevalent 20% in HIV+ homosexual men and 27% in AIDS homosexual men). HPVDNA 16 and 18 are the most commonly found in anogenital condyloma and in 1% of pre-malignant lesions and oral cancer. OBJECTIVE: The aim of this publication is to report a clinic case of an AIDS patient with spreading condylomas in oral mucosa, one of these diagnosed as "carcinoma in situ". CASE REPORT: A 46 year-old male diagnosed with AIDS due to a history of intestinal Mycobacterium avium, esophageal candidiasis and Citomegalovirus (CMV) retinitis. He came to our consultation as an out-patient with a healthy appearance under highly effective antiretroviral therapy (HAART). On the exploration we found spreading condylomas in all of the oral mucosa. Biopsies were performed and histological and immunohistochemical studies revealed the characteristic features of HPV infection. PCRRLFP assay was added in order to obtain a sensible typification of HPVDNA. One localization of condyloma, in the upper lip mucosa was diagnosed as "carcinoma in situ". PVDNA types 18 and 51 were confirmed. Therapy was establish with Laser carbon-dioxide application in three sessions, followed by surgical excision with electro scalpel. Carcinoma in situ required excision surgery. A local therapy was performed and follow up. CONCLUSION: We have not find any report about HPVDNA 51 in oral "carcinoma in situ". Early detection of HPV lesions in oral mucosa is important in improving prevention of oral cancer.

RESUMO

La úlcera aftosa recurrente (RAU) es una lesión muy dolorosa de la mucosa oral que afecta entre el 2 por ciento y 20 por ciento de la población mundial. En personas inmunocompetentes es una enfermedad complicada, de tratamiento muy difícil. En los pacientes con sindrome de inmunodeficiencia humana, RAU es más persistente y severamente debilitante. Las últimas comunicaciones publicadas han mostrado sumo interés en el estudio inmunológico de esta patología. Objetivos: 1-investigar la expresión de moléculas de adhesión (MA) y sus ligandos , subpoblaciones leucocitarias, el gen antioapoptótico BCL-2; células Natural Killer y macrófagos en pacientes RAU+ (VIH+ y VIH-) 2-Establecer diferencias entre pacientes RAU + (VIH+ y VIH-) y pacientes RAU-(VIH+/vIH-). . 3-Presentar nuestra hipótesis sobre la etiopatogenia de activación endotelial y probable proceso de vasculitis en pacientes con RAU, especialmente aquellos VIH+. Material y métodos: Para este estudio fueron reclutados pacientes mayores de 15 años de edad, VIH negativos y VIH positivos con RAU y sin RAU. El estudio de biopsias fue realizado para histología con tinción de hematoxilina-eosina y con Inmunoperoxidasa usando anticuerpos monoclonales primarios para los siguientes antígenos: ICAM-1(CD54), CD 11, CD 18, CD56 (NK), CD 15 (PMN), CD62:E-selectin, CD31, BM-1 (lewys-Y), BCL-2, CD8, CD68.La intensidad de las tinciones fueron evaluadas semicuantitativamente como: Ps: positivo suave, Rpositivo+, Pp: positivo ++, PPPpositivo +++, E/P: intra epitelial positivo, N negativo, L: leucocitos, W: vasos, E: epitelio. Se realizó estudio estadístico y registro fotográfico. Resultados: Se observaron diferentes patrones de tinción en asociación con las MA entre la mucosa normal y las RAU+ en pacientes VIH+ y control VIH-. En la submucosa, tanto el estudio histológico como el inmunohistoquímico mostraron un fenómeno de vasculitis con alteración de las paredes de los capilares, arteriolas y vénulas, con un infiltrado inflamatorio de neutrófilos y leucociotoclasia. Conclusión: la presencia de una alta expresión de CD31, CD15 y CD54 en pacientes RAU+ lleva a soportar la hipótesis que una activación de células endoteliales y un procesos de vasculitis puede yacer bajo RAU, con algunas diferencias entre las subpoblaciones VIH+ y VIH- (AU)

RESUMO

UNLABELLED: A variety of exfoliative cheilitis has been observed in reactive HIV-1 patients subjected to high activity antiretroviral therapy (HAART). The lesions exhibit exfoliation, crater formation, fissuring, erosions and/or the formation of papules, vesicles and blisters associated to erythema and edema. The condition is not included in the 1993 EEC Clearinghouse classification (1) of oral lesions associated with HIV infection. In an earlier series of 1899 patients (2), we failed to observe this pathology and have only found one similar case described in the literature to date (3). OBJECTIVE: We present a series of 6 patients with HIV infection and morpho-histological alterations of the labial semimucosa, subjected to HAART. MATERIALS AND METHODS: The 6 patients were selected from among 20 HIV-positive individuals treated in our Infectious Diseases Unit with a combination of nucleoside and non-nucleoside reverse transcriptase inhibitors and protease inhibitors requiring stomatological care for painful lesions of the lips and oral cavity. The study was conducted over a 6-month period between May and October 1998. An analysis was made of the case histories, CD4-positive cell counts and viral load. The stomatological explorations were completed with biopsies, hematoxylin-eosin staining and immunohistochemical studies involving AE1 and AE3 monoclonal antibodies, vimentin, protein S-100, carcinoembryonic antigen (CEA), laminin, CD8, HLA-DR, BM-1 and CD31 markers. At the time of detection of the oral lesions, the patients had received different combinations of the following antiretroviral treatments: stavudine (D4T), zalcitabine (DDC), didanosine (DDI), zidovudine (AZT), lamivudine (3TC), nelfinavir (NFV), saquinavir (SQV), ritonavir (RTV), hydroxyurea (HU), indinavir (IDN) and efavirenz (EFV). RESULTS: There were four males and two females (age range 31-42 years). The CD4-positive and viral load ranges were 70-330 cells/mm3 and 200-500,200 copies, respectively. Stomatologic manifestations: The oral clinical manifestations consisted of desquamation, cracks, fissures, scabs, ulcerations, edema, erythema, multiple punctate xanthomas (1 case), dryness and labial semimucosal thickening. Microscopic study: Microscopically, the lesions consisted of ulcerations with adjacent hyperkeratosis and suprabasal vacuolization accompanied by a dense lymphocyte infiltrate within the chorion. Inmunohistochemistry: The immunohistochemical study in turn revealed surface epithelial alterations with AE1-AE3 monoclonal antibody labeling. Membrane glycoprotein activation (laminin) was detected, along with the presence of cytotoxic lymphocytes (CD8) and activated lymphocytes (BM-1). CD31 labeling in turn indicated endothelial activation.

RESUMO

INTRODUCTION: Histoplasmosis is a deep mycosis which is increasingly seen in HIV disease. It has emerged as a relatively common infection in Argentina, mainly in HIV-infected and other immunocompromised persons, and is often disseminated (DH). OBJECTIVE: The aim of this study was to describe 32 HIV-I-seropositive patients with AIDS who had DH, 21 of whom presented orofacial manifestations, and their treatment. SUBJECTS AND METHODS: A retrospective study of 876 HIV-seropositive patients revealed 32 with a clinical diagnosis of DH confirmed by special stains on histopathologic specimens, or by culture. RESULTS: Thirty-two HIV-infected patients had DH. Two-thirds (21 patients) had oral lesions of histoplasmosis, of which six presented with oral cavity (OC) lesions as the sole orofacial manifestation of disease, nine patients presented oral and facial (OF) lesions and six presented facial lesions only. A unique case of submandibular histoplasmosis is also reported. Antifungal therapy cleared more than 90% of the orofacial and disseminated lesions of histoplasmosis. Over the 7-year period there was a mortality of 85%. CONCLUSION: DH should be considered as a possible diagnosis in HIV patients with chronic ulcerative or nodular orofacial or oral lesions. Itraconazole is an effective and acceptable therapy.
