ABSTRACT

Abstract: Introduction: about 0.1 percent of the population suffers from necrotizing ulcerative gingivitis, a disease of rapid progression and acute manifestation, which may progress to necrotizing ulcerative periodontitis and eventually to bone sequestration and loss of gingival tissue. Case report: A 21-year-old female patient undergoing orthodontic treatment for six months, diagnosed with necrotizing ulcerative gingivitis due to acute pain in the gingival tissue, spontaneous bleeding, halitosis and abundant plaque. The treatment was conservative and effective, obtaining total remission of the lesion after seven days and three months of postoperative follow-up. Conclusion: Today there are no epidemiological or clinical reports that support the relationship of necrotizing ulcerative gingivitis and orthodontic treatment. Prevention is critical to the success of the treatment, which is why the dentist should recognize the clinical features of necrotizing ulcerative gingivitis to raise awareness of its risks in the orthodontic patient.


Resumen: Introducción: alrededor del 0.1 por ciento de la población padece de gingivitis ulcerativa necrotizante, una enfermedad de progresión rápida y de presentación aguda que puede progresar a periodontitis ulcerativa necrotizante llegando a desarrollarse secuestros óseos y la pérdida de tejido gingival. Reporte del caso: Paciente femenino de 21 años de edad bajo seis meses de tratamiento ortodóntico, quien fue diagnosticada con gingivitis ulcerativa necrosante, debido a dolor agudo en el tejido gingival, sangrado espontáneo, halitosis y abundante placa bacteriana. El tratamiento fue llevado a cabo de manera conservadora y efectiva, obteniendo la remisión total de la lesión al término de siete días y los tres meses de seguimiento postoperatorio. Conclusión: Hoy en día no existen reportes epidemiológicos ni clínicos que sustenten la relación de la gingivitis ulcerativa necrotizante y el tratamiento ortodóntico. La prevención es decisiva para el éxito del tratamiento, es por ello que el odontólogo debe conocer las características clínicas de la gingivitis ulcerativa necrotizante para hacer conciencia en el paciente ortodóntico.

ABSTRACT

Extranodal natural killer (NK)/T-cell lymphoma is an aggressive malignant tumor with distinctive clinicopathological features, characterized by vascular invasion and destruction, prominent necrosis, cytotoxic lymphocyte phenotype and a strong association with Epstein-Barr virus. Here is reported an extranodal nasal NK/T-cell lymphoma case, involving the maxillary sinus, floor of the orbit, and interestingly extending to the oral cavity through the alveolar bone and buccal mucosa, preserving the palate, leading to a primary misdiagnosis of aggressive periodontal disease. Moreover, this work investigated for the first time the immunohistochemical expression of fatty acid synthase (FASN) and glucose transporter 1 (GLUT-1) proteins in this neoplasia. FASN showed strong cytoplasmatic expression in the neoplastic cells, whereas GLUT-1 and CD44 were negative. These findings suggest that the expression of FASN and the loss of CD44 might be involved in the pathogenesis of the extranodal nasal NK/T-cell lymphoma, and that GLUT-1 may not participate in the survival adaptation of the tumor cells to the hypoxic environment. Further studies with larger series are required to confirm these initial results.


O linfoma de células natural killers (NK)/T extranodal é um tumor maligno agressivo com características clinicopatológicas distintas, caracterizadas por invasão e destruição vasculares, necrose proeminente, fenótipo linfocítico citotóxico e uma forte associação com o vírus Epstein-Barr. Relatamos aqui um caso de linfoma de células NK/T nasal extranodal, envolvendo o seio maxilar, assoalho de órbita, e interessantemente estendendo-se para a cavidade oral através do osso alveolar e mucosa vestibular, preservando o palato, levando a um diagnóstico inicial equivocado de doença periodontal agressiva. Ainda, nós investigamos pela primeira vez a expressão imunoistoquímica das proteínas Fatty acid sinthase (FASN) e glucose transporter 1 (GLUT-1) nesta neoplasia. FASN revelou uma forte expressão citoplasmática nas células neoplásicas, enquanto GLUT-1 e CD44 foram negativas. Estes achados sugerem que a expressão de FASN e a perda de CD44 podem estar envolvidas na patogênese do linfoma de células NK/T nasal extranodal, e que GLUT-1 não deve participar da adaptação das células tumorais ao ambiente de hipóxia. Estudos adicionais com séries maiores são necessários para confirmar nossos resultados iniciais.

ABSTRACT

As doenças periodontais necrosantes (DPNs) são as formas mais graves de doença periodontal causada pela placa bacteriana. Nas DPNs, as bactérias são mais agressivas do que as observadas em uma periodontite crônica e, quando associadas a uma saúde debilitada do indivíduo, causam um dano ainda maior ao periodonto. Por outro lado, as DPNs têm uma prevalência extremamente baixa na população, o que faz com que casos diagnosticados dessa doença devam ser documentados e divulgados, para contribuir para o conhecimento da mesma pelos profissionais de saúde. Dessa forma, o objetivo do presente trabalho é ilustrar, através de um caso clínico, as características clínicas de uma das DPNs e as etapas clínicas do tratamento correspondente. Um indivíduo com 22 anos de idade compareceu à clínica odontológica para atendimento de urgência, apresentando como sinais e sintomas: febre, sangramento espontâneo, supuração, dor e halitose extrema. Clinicamente, apresentava na gengiva interproximal de diversos dentes ulcerações e necrose com ampla extensão, necrose e exposição de osso alveolar interproximal, e pobre higiene bucal. Radiograficamente, constataram-se perdas ósseas horizontais. O tratamento foi baseado no diagnóstico de periodontite ulcerativa necrosante. Noventa dias após o início do tratamento, foi realizada reavaliação periodontal, observando-se ausência de bolsas periodontais e permanência dos defeitos anatômicos produzidos pela inflamação. Após um ano do início do tratamento, observaram-se focos de placa bacteriana e cálculo supragengival, porém não foram observadas bolsas periodontais e sangramento à sondagem.


Necrotizing Periodontal Diseases (NPDs) are the most severe inflammatory periodontal disorders caused by plaque bacteria. In the NPDs the bacteria are more aggressive than those observed in chronic periodontitis and when combined with a poor health of the patient causing a further damage to the periodontium. On the other hand, the prevalence of NPD is extremely low in the population, however, diagnosed cases of this disease should be documented and disseminated to contribute to the knowledge by health professionals. The objective of this paper is to illustrate through a clinical case the clinical characteristics of one of the NPDs and the stages of its treatment. A 22-year-old patient attended in the dental clinic for urgent care presenting the following signs and symptoms: fever, spontaneous bleeding, suppuration, pain and extreme halitosis. Clinically, there were ulcerations and extensive necrosis in the interproximal gingiva of several teeth, exposure of interproximal alveolar bone and poor oral hygiene. In the radiograph it was found horizontal bone loss. The treatment realized was based on the diagnostic of Necrotizing Ulcerative Periodontitis. Ninety days after the treatment beginning it was performed a periodontal reevaluation, and there was absence of periodontal pockets, and anatomic defects produced by the inflammation were observed. After one year of the treatment beginning it was observed plaque and supragengival calculus, but pockets and bleeding on probing were not observed.

ABSTRACT

Las lesiones ulcerativas necrotizantes han sido documentadas a través de la historia. Su denominación, diagnóstico y tratamiento ha evolucionado con el paso de los años, hasta el presente, partiendo en Gingivitis Ulcerativa Necrotizante (GUN) caracterizada como una lesión de rápida evolución, de dolor paroxístico, confinada al margen gingival y papilar. La Periodontitis Ulcerativa Necrotizante (PUN), es ampliamente considerada como una evolución de GUN, involucrando al tejido óseo y a las estructuras de inserción, la falta de medidas terapéuticas ante estas entidades, generará la evolución a Estomatitis Ulcerativa Necrotizante (EUN), la cual involucra estructuras diferentes a los tejidos dentales y de soporte, como las mucosas circundantes. Dichas entidades exhiben signos patognomónicos comunes como sangrado, ulceración, necrosis papilar, supuración, dolor y mal olor, con predominio de microflora específica: fusobacterias y espiroquetas asociadasa factores predisponentes como stress, cigarrillo, desnutrición y alcohol. En la actualidad, la más fuerte asociación epidemiológica es con el Virus de inmunodeficiencia humana (VIH), en pacientes que presentan estados de inmunosupresión menores a 200.000 linfocitos T CD4, por tal motivolos portadores de cualquiera de estos tipos de lesión deben orientar al clínico la necesidad de confirmar el diagnóstico presuntivo de seropositividad. Los parámetros de tratamiento están encausados a la erradicación del agente etiológico, empleando medios mecánicos, como detartraje y alisado radicular apoyado en empleo de antimicrobianos locales y sistémicos, y el control de los factores de riesgo.


Necrotizing ulcerative lesions have been documented throughout history. Your name, diagnosis and treatment has evolved over the years, to date, starting in Necrotizing Ulcerative Gingivitis (NUG) characterized as a rapidly developing lesion, paroxysmal pain, confined to the gingival margin and papillary. Necrotizing Ulcerative Periodontitis (NUP) is widely regarded as an evolution of NUG, involving the bone and the insertion structures, lack of therapeutic measures against these entities generate evolution, Necrotizing Ulcerative Stomatitis (EUN), which involves different structures to the dental tissues and support, as the surrounding mucosa. Such entities exhibit common pathognomonic signs such as bleeding, ulceration, papillary necrosis, suppuration, pain and bad smell, with a predominance of specific microflora: Fusobacteria and spirochetes associated with predisposing factors such as stress, smoking, malnutrition and alcohol. Currently, the strongest epidemiological association is with the human immunodeficiency virus (HIV) in patients with immunosuppressive states below 200.000 CD4 T cells, as such carriers of either type of injury should guide the clinician to confirm the presumptive diagnosis of HIV infection. The treatment parameters are prosecuted to the eradication of the causative agent using mechanical means such as scaling and root planning supported employment for local and systemic antimicrobials, and control of risk factors.

ABSTRACT

Se realizó un estudio observacional descriptivo prospectivo de corte transversal, con el objetivo de determinar el comportamiento de la gingivitis ulceronecrotizante aguda, en 37 pacientes entre 15 y 50 años de edad, quienes acudieron al servicio de estomatología de Conuco Viejo, municipio García, en el período comprendido de enero a diciembre de 2009. Se caracterizaron a los pacientes estudiados según variables sociodemográficas, y se identificó los factores de riesgo presentes, así como el nivel de conocimientos sobre salud bucodental. Se les realizó un examen clínico minucioso y se le aplicó una encuesta de conocimiento de salud bucal. Se encontró que los adolescentes de 15-20 años y adultos jóvenes de 21-26 años fueron los más afectados, con un 32,44 por ciento y 29,73 por ciento, respectivamente. El sexo femenino, con un 62,16 por ciento, el nivel educacional secundaria básica con 40,55 por ciento fueron los de mayor porcentaje. Dentro de lo factores de riesgo, los mayores por cientos correspondieron a la gingivitis crónica en los locales, con un 75,67 por ciento, mientras que el estrés en los generales, con 59,45 por ciento. Al aplicarse la encuesta de conocimientos un 54,05 por ciento de los pacientes estudiados fue evaluado de mal.


We carried out a transversal prospective descriptive observational study with the objective of determining the behavior of acute ultranecrotizing gingivitis, in 37 15 to 50 years-old patients, who visited the Stomatologic Service of Conuco Viejo, municipality of García, in the period from January to December 2009. The studied patients were characterized according to sociodemographic variables and the present risk facts were identified, and also the level of knowledge on buccal dental health. A thorough clinic examination was made and the patients applied an inquiry of knowledge on buccal health. We found that 15-20 years-old adolescents and 21-25 years-old young adults were the most affected patients, with 32,44per cent and 29,73 per cent respectively. The female genre, with 62,16 per cent, and the high school scholarship with 40,55 per cent showed the highest percentages. Among the local risk facts, the highest percents corresponded to chronic gingivitis, with 75,67 per cent, while stress represented the highest percent among general risk facts, with 59,45 per cent. As the result of the enquiry, the knowledge of 54,05 per cent of the studied patients were evaluated as unsatisfactory.

ABSTRACT

Las enfermedades de vías respiratorias superiores y sus complicaciones pueden poner en peligro la vida; por consiguiente, se necesita un método sistemático para el diagnóstico rápido y tratamiento adecuado. Al analizar los signos y síntomas se puede establecer un diagnóstico diferencial. Las infecciones graves de vías respiratorias superiores pueden situarse en tres categorías expuestas en este artículo: síndrome catarral agudo, síndrome de amigdalofaringitis o síndrome de crup laríngeo. Este sistema de clasificación hace que el diagnóstico sea rápido y permita que el tratamiento adecuado se inicie con prontitud
