ABSTRACT

Abstract Introduction Molecular studies about carcinomas of the oral cavity and oropharynx demonstrate the presence of human papilomavirus genome in these tumors, reinforcing the participation of human papilomavirus in oral carcinogenesis. Objectives This study aimed to determine the prevalence of human papilomavirus and genotype distribution of HPV16 and HPV18 in oral cavity and oropharynx carcinomas, as well as their association with clinical characteristics of the tumors. Methods This is a retrospective study, with clinical data collected from 82 patients. Human papilomavirus detection was conducted on specimens of oral cavity and oropharynx carcinomas included in paraffin blocks. Patients were assisted in a cancer reference center, in the central region of Brazil, between 2005 and 2007. Polymerase chain reaction was used for the detection and genotyping of human papilomavirus. Results Among the patients evaluated, 78% were male. The average age of the group was about 58 years. Risk factors, such as smoking (78%) and alcohol consumption (70.8%) were recorded for the group. HPV DNA was detected in 21 cases (25.6%; 95% confidence interval 16.9–36.6) of which 33.3% were HPV16 and 14.3% were HPV18. The presence of lymph node metastases and registered deaths were less frequent in human papilomavirus positive tumors, suggesting a better prognosis for these cases; however, the differences between the groups were not statistically significant. Conclusion The results obtained in the present study, with respect to the presence of the high-risk HPV16 and HPV18 genotypes, highlight the importance of human papilomavirus vaccination in the control of oral cavity and oropharynx carcinomas.


Resumo Introdução Estudos moleculares sobre carcinomas da cavidade oral e orofaringe demonstram a presença do genoma do papilomavírus humano (HPV) nesses tumores, o que enfatiza a participação do HPV na carcinogênese oral. Objetivos Determinar a prevalência de HPV e a distribuição genotípica de HPV16 e HPV18 nos carcinomas de cavidade oral e orofaringe, bem como sua associação com as características clínicas dos tumores. Método Estudo retrospectivo, com dados clínicos coletados de 82 pacientes. A detecção de HPV foi feita em amostras de carcinomas de cavidade oral e orofaringe incluídos em blocos de parafina. Os pacientes foram atendidos em um centro de referência para tratamento do câncer, na região central do Brasil, entre 2005 e 2007. Foi usada a reação em cadeia de polimerase (PCR) para a detecção e genotipagem do HPV. Resultados Entre os pacientes avaliados, 78% eram homens. A média de idade do grupo era de 58 anos. Fatores de risco como o tabagismo (78%) e consumo de álcool (70,8%) foram registrados para o grupo. HPV DNA foi detectado em 21 casos (25,6%; IC de 95%, 16,9-36,6), dos quais 33,3% eram HPV16 e 14,3% eram HPV18. A presença de metástases em linfonodos e os óbitos registrados foram menos frequentes em tumores positivos para HPV, o que sugere melhor prognóstico para esses casos; contudo, as diferenças entre os grupos não foram estatisticamente significantes. Conclusão Os resultados obtidos no presente estudo, com respeito à presença de genótipos de alto risco de HPV16 e HPV18, destacam a importância da vacinação para HPV no controle dos carcinomas de cavidade oral e orofaringe.

ABSTRACT

A assistência a pacientes vítimas de abuso sexual deve ser intersetorial e interdisciplinar, incluindo interface com questões policiais e judiciais. Nesse contexto, o médico tem dever ético e legal de prestar atendimento prioritário a essas pacientes. É necessário que o serviço de saúde realize exame físico, exame ginecológico, coleta de amostras para diagnóstico de infecções genitais e coleta de material para identificação do agressor. As evidências mostram que a violência contra a mulher tem impacto sobre a saúde física e mental desta. A equipe médica, portanto, deve estar preparada para oferecer apoio psicossocial. Outra preocupação médica é diminuir ao máximo as consequências do ato de violência, seja protegendo a mulher de doenças sexualmente transmissíveis ou de gravidez traumática. A paciente vítima de violência sexual, ocasional e sem uso de preservativo, deve receber no serviço de urgência profilaxia contra HIV, hepatite B, sífilis, gonorreia, clamidiose, cancro mole, tricomoníase e tétano. Além de ter direito a receber anticoncepção de emergência, o aborto nessas pacientes pode ser feito legalmente. Para isso, basta a autorização da paciente e/ou do responsável, dependendo da idade da paciente, sendo incorreta e ilegal a exigência de Boletim de Ocorrência Policial ou laudo do Instituto Médico Legal.


The assistance to patients who are victims of sexual abuse should be intersectoral and interdisciplinary, including interface with police and justice affairs. In this context the physician has an ethical and legal obligation to give priority attention to these patients. It is necessary for the health service to perform physical examination, gynecological examination, collection of samples for diagnosis of genital infections and collection of material for the aggressor’s identification. Evidences shows that violence against women has an impact on both their mental and physical health. The medical team, therefore, must be prepared to offer psychosocial support. Another medical concern is to minimize as much as possible the consequences of the act of violence, either by protecting the woman from Sexually transmitted Diseases or from traumatic pregnancy. The patient who was suffered occasional sexual violence without the use of a condom must receive in the emergency service prophylaxis against HIV, type B hepatitis, syphilis, gonorrhea, chlamydia, chancroid, trichomoniasis and tetanus. Besides having the right to receive emergency contraception, abortion in these patients can be legally done. It is only required the written consent of the patient and/or the person legally responsible for her, depending on the patient’s age, and the requirement of the Police or Forensic Medicine reports is considered both incorrect and illegal.

ABSTRACT

Este artigo trata de paciente com 54 anos, atendida no Hospital Júlia Kubitschek, com relato de ter sido vítima de violência sexual. O agressor armado invadiu sua casa e a obrigou, mediante ameaça de morte, a manter com ele sexo vaginal, anal e oral, sem uso de preservativo. Apresentava-se ansiosa e chorosa. Havia lesão contusa em região escapular esquerda e leve hiperemia de grande lábio direito. O exame especular e a inspeção da região anal não apresentavam alterações. Foram realizadas avaliação laboratorial e profilaxia para doenças sexualmente transmissíveis (DSTs), incluindo administração de antirretrovirais. Foi encaminhada ao ambulatório de vítimas de violência sexual.


This article is about a 54-year-old female patient, assisted at Júlia Kubitschek Hospital, who reported having been victim of sexual violence. According to her, the armed aggressor broke into her house and forced her by threat of death to have vaginal, anal and oral sex with him without using condom. The patient was anxious and tearful. There were blunt injury in the left scapular region (shoulder blade area) and mild hyperemia of the right labium. Speculum examination and inspection of the anal region showed no alterations. The treatment included laboratory tests and prophylaxis for Sexually Transmitted Diseases (STDs), including administration of antiretroviral medication. The patient was referred to an outpatient center for victims of sexual violence.

ABSTRACT

Objetivo: revisar a literatura sobre as inter-relações entre as vias aéreas superiores e inferiores, com enfoque na asma e na rinite alérgica. Métodos: pesquisa não sistemática realizada nas bases Medline e LILACS nos últimos 20 anos, usando os descritores "asthma" "allergic rhinitis" "interaction" "united airways". Resultados: vários estudos clínicos, epidemiológicos, experimentais sugerem a hipótese de que asma e rinite alérgica são a expressão de uma única doença que acomete as vias aéreas. Pacientes com asma frequentemente apresentam rinite alérgica e a rinite alérgica não tratada dificulta o controle da asma. Do ponto de vista histológico, as mucosas nasais e brônquicas compartilham várias semelhanças. Alterações da mucosa nasal causam alterações mediadas por respostas fisiológicas na mucosa brônquica, e vice-versa. Esse corpo de evidências culminou com a iniciativa ARIA (Allergic Rhinitis and its Impact on Asthma), que enfatiza a necessidade de tratar a rinite alérgica no paciente com asma. Conclusões: a hipótese de que asma e rinite alérgica são a expressão de uma única doença que acomete o trato respiratório tem se consolidado e reforça a importância da busca por tratamentos que contemplem de forma integrada a comorbidade.

Objective: To review the literature about interactions between upper and lower airways with emphasis in asthma and allergic rhinitis. Methods: A non systematic review was conducted using Medline and LILACS in the last twenty years, using "asthma" "allergic rhinitis" "interaction" "united airways" as descriptors. Results: Several clinical, epidemiological, experimental studies suggest the hypothesis that asthma and allergic rhinitis are the expression of a single disease that affects the airways. Patients with Asthma often have allergic rhinitis, and untreated allergic rhinitis make asthma control difficult. From the histological point of view, the nasal and bronchial mucosa share many similarities. Changes in the nasal mucosa cause changes in bronchial mucosa, mediated by physiological responses and vice-versa. These findings led to the initiative (ARIA) Allergic Rhinitis and its Impact on Asthma, that emphasizes the need to treat allergic rhinitis in patients with asthma. Conclusions: The hypothesis that allergic rhinitis and asthma are the expression of a single disease that affects the respiratory tract has been strengthened and reinforced the importance of searching for integrated treatments that aim the seamless comorbidity (AU)
