O papel da odontologia no diagnóstico da doença enxerto-contra-hospedeiro / The role of dentistry in the diagnosis of Graft-versus-host disease

Objetivo: Elucidar quais as formas mais adequadas de se proceder para que haja um efetivo diagnóstico da Doença Enxerto-Contra-Hospedeiro pelo cirurgião-dentista. Revisão de literatura: A Doença Enxerto Contra Hospedeiro acomete diversos pacientes que realizam transplante de células tronco hematopoiéticas. Os sinais clínicos muitas vezes são manifestados apenas na cavidade bucal e, por isso, é importante que o cirurgião-dentista tenha conhecimento. Esta patologia é proveniente de uma complicação do TCTH (Transplante de Células Tronco Hematopoiéticas) alogênico, onde ocorre uma resposta de ativação de linfócitos T do doador e um reconhecimento de antígenos contra o receptor. Discussão: As alterações mais evidentes são lesões ulceradas, estrias brancas, mucocele, leucoedema, lesões bolhosas, ardência, dor e xerostomia. Estes aspectos tendem a corresponder a um diagnóstico de lesões malignas, síndrome de Sjogren, lúpus e líquen plano. A biópsia é fundamental para o diagnóstico, assim como para graduar a severidade da Doença Enxerto Contra Hospedeiro. Conclusão: Caso o cirurgião-dentista identifique algum dos sinais, deverá alertar à equipe médica do paciente para iniciar o tratamento e evitar a recidiva da doença original.

Aim: elucidate which are the most appropriate ways to proceed so that there is an effective diagnosis of Graft--versus-Host Disease by the dentist. Literature review: Graft-versus-host disease affects several patients who undergo hematopoietic stem cell transplantation. Clinical signs are often manifested in the oral cavity only, rea-son why it is important the dentist to be aware of them. This pathology is caused by a complication of allogeneic HSCT, in which there is an activation response of donor T lymphocytes and a recognition of antigens against the recipient. Discussion: The most evident changes are ulcerated lesions, white streaks, mucocele, leukedema, bullous lesions, burning, pain and Xerostomia. These aspects tend to correspond to a diagnosis of malignant lesions, Sjogren's syndrome, lupus and lichen planus. A biopsy is essential for diagnosis as well as for grading the severity of Graft versus Host Disease. Conclusion: If the dental surgeon identifies any of the mentioned signs, he must alert the patient's medical team to start treatment to prevent the recurrence of the original disease.

Syphilis and HIV co-infection in patients who attend an AIDS outpatient clinic in Vitoria, Brazil.

Our goal was to determine the prevalence of, and risk factors associated with, syphilis in HIV-infected patients who attend an AIDS outpatient clinic in Vitoria, Brazil. We conducted a cross-sectional study-including interviews for demographic, behavioral, and clinical characteristics-and blood collection (venipuncture and fingerstick) for VDRL and treponemal tests (rapid test) in a total of 438 patients. The mean age was 43.0 years (SD = 11), and mean years of school was 8.1 (SD = 4.2). The prevalence of syphilis was 5.3 % (95 % CI 3.3-7.3). The treponemal test was positive in 18.9 % of participants. In multivariate analysis, prevalent syphilis infection was independently associated with male gender (AOR 4.6, 95 % CI 1.1-20.0), a history of male-male sex (AOR 1.8, 95 % CI 1.6-4.1), current use of antiretroviral therapy (AOR 5.5, 95 % CI 1.7-16.7), and history of treated syphilis infection (AOR 5.5, 95 % CI 2.0-15.8). Syphilis prevalence was high in patients living with HIV/AIDS who attend an AIDS clinic; therefore, routine sexually transmitted infections counseling and screening should be included in their care.
