Mucoceles are cystic masses that generally affect the sinuses. It occurs as a result from obstruction of the ostium of a sinus and consequential accumulation of mucus. Frontal and ethmoid sinuses are mostly affected. Usually, the clinical symptoms are insidious, varying with the extent of the affected region. The treatment is surgical and endoscopic surgery is the method of choice in most cases. The present study is aimed at describing the main characteristics of paranasal sinuses mucoceles, demonstrating and illustrating a series of atypical presentations with emphasis on imaging findings. Keywords: Paranasal sinuses; Mucocele; Presentation; Atypical.As mucoceles são formações císticas que podem afetar os seios paranasais. Ocorrem quando há obstrução na drenagem de um seio, com resultante acúmulo de secreção. Os seios frontal e etmoidal são os mais acometidos. A apresentação clínica normalmente tem sintomas insidiosos que variam com a extensão da região acometida. O tratamento é cirúrgico, sendo a cirurgia endoscópica o método de escolha na maioria dos casos. O objetivo do nosso estudo é descrever as principais características das mucoceles dos seios paranasais, bem como demonstrar e ilustrar uma série de apresentações atípicas, com ênfase nos achados de imagem. Unitermos: Seios paranasais; Mucocele; Apresentação; Atípica. AbstractResumo
RESUMOIntrodução: asma e obesidade são problemas frequentes de saúde. Objetivos: avaliar a prevalência de obesidade e obesidade abdominal em amostra de pacientes asmáticos do Ambulatório de Pneumologia da Faculdade de Ciências Médicas de Minas Gerais e correlacioná-las com o controle da sintomatologia da asma. Métodos: 74 pacientes com asma, com idade igual ou superior a 18 anos, foram avaliados entre março e julho de 2010. Foram analisadas nesses pacientes as medidas do índice de massa corpórea (IMC), da circunferência abdominal (CA) e o Questionário de Controle da Asma (ACQ-5). Resultados: a amostra era constituída por 57 mulheres (77,0%) e 17 homens (23,0%); 83,8% apresentavam CA acima do recomendado e 44,6% eram obesos. Houve correlação positiva significativa entre o escore total do ACQ-5 e a CA (p=0,006) e IMC (p=0,015). Em relação ao escore categorizado do ACQ-5, foram propostos dois pontos de corte -0,75 e 1,50. Considerando o primeiro ponto de corte para o ACQ-5, verificou-se significativa associação com o IMC (p=0,023) e com a CA (p=0,034). Não foi verificada significativa associação com algum dos índices com o segundo ponto de corte no escore médio do ACQ-5. Conclusões: constatou--se elevada prevalência de obesidade e obesidade abdominal em população de asmáticos e provável influência destas no controle da sintomatologia da asma.Palavras-chave: Obesidade; Circunferência Abdominal; Asma. ABStRACtIntroduction: Asthma and obesity are common health problems. Objectives: To assess the prevalence of obesity and abdominal obesity in a sample of asthmatic patients at the Pulmonology Clinic at the Minas Gerais School of Medical Sciences and correlate them with the control of asthma symptoms. Methods: 74 patients with asthma, aged 18 years or more, were evaluated between March and July 2010. We assessed the body mass index (BMI), waist circumference (WC) and the Asthma Control Questionnaire (ACQ-5) for these patients. Results: The sample consisted of 57 women (77.0%) and 17 men (23.0%); 83.8% were above the recommended WC and 44.6% were obese. There was a significant positive correlation between the total ACQ-5 score and WC (p = 0.006) and BMI (p = 0.015). Cutoff points of -0.75 and 1.50 in relation to the categorized ACQ-5 score were proposed. Considering the first cutoff point for the ACQ-5, there was a significant association with BMI (p = 0.023) and WC (p = 0.034). There was no significant association with any of the measurements with the second cut-off point of the average ACQ-5 score. Conclusions: We found a high prevalence of obesity and abdominal obesity in a population of asthmatic individuals and their possible influence in the control of asthma symptoms.
This is a case report on a giant cell tumor (GCT) in the proximal phalanx of the third finger of the left hand, with pulmonary metastasis. The patient presented pain in the finger without any previous history of trauma. Clinical examination, radiographic imaging and magnetic resonance imaging were carried out. A histological evaluation was carried out from an incisional biopsy, taking the hypothesis of GCT. The patient underwent amputation of the finger and the diagnosis was confirmed by means of microscopy on the specimen. The patient was followed up because of the risk of lung metastasis, which was shown by radiographic examination and computed tomography on the chest, and thoracotomy was performed. Since then, there has been an improvement in the symptoms that had been reported preoperatively, and no local recurrence or new metastasis has been found.
