Prevalence of Microorganisms and Immunoglobulins in Children with Tonsillar Hypertrophy and Adenoiditis

Introduction: Benign idiopathic tonsillar hypertrophy (HBI) may affect a child's quality of life and sleep. Several studies have sought to relate the clinical features of HBI with the infectious and/or immunologic changes that occur. Objective: To increase the knowledge of the etiology of HBI. Data Synthesis: From 2012 to 2013 we conducted a retrospective observational study of 101 children with HBI who underwent tonsillectomies at Ambulatory ENT General Hospital of the East Zone of São Paulo City, a region with a poor socioeconomic population. Preoperative serologic results were available to confirm mononucleosis, cytomegalovirus, anti-streptolysin O (ASLO) and immunoglobulins. The mean patient age was 5.8 years (55% male, 45% female). Using the Mann-Whitney U test, we identified significant gender differences in the parameters of immunoglobulins (Ig) M (IgM), IgA, and IgE. Forty-seven percent of the patients had increased ASLO levels, and 37% had increased IgE levels. Conclusion: An evaluation of a patient's serologic parameters and laboratory results may be relevant to the etiology and prevention of HBI. Based on the results obtained from the study sample, the identification of etiologic agents and causative factors remain a public health challenge that affects the quality of life of children...

I diretriz de ressuscitação cardiopulmonar e cuidados cardiovasculares de emergência da Sociedade Brasileira de Cardiologia: resumo executivo / I guideline for cardiopulmonary resuscitation and emergency cardiovascular care - Brazilian Society of Cardiology: executive summary

Apesar de avanços nos últimos anos relacionados à prevenção e a tratamento, muitas são as vidas perdidas anualmente no Brasil relacionado à parada cardíaca e a eventos cardiovasculares em geral. O Suporte Básico de Vida envolve o atendimento às emergências cardiovasculares principalmente em ambiente pré-hospitalar, enfatizando reconhecimento e realização precoces das manobras de ressuscitação cardiopulmonar com foco na realização de compressões torácicas de boa qualidade, assim como na rápida desfibrilação, por meio da implementação dos programas de acesso público à desfibrilação. Esses aspectos são de fundamental importância e podem fazer diferença no desfecho dos casos como sobrevida hospitalar sem sequelas neurológicas. O início precoce do Suporte Avançado de Vida em Cardiologia também possui papel essencial, mantendo, durante todo o atendimento, a qualidade das compressões torácicas, adequado manejo da via aérea, tratamento específico dos diferentes ritmos de parada, desfibrilação, avaliação e tratamento das possíveis causas. Mais recentemente dá-se ênfase a cuidados pós-ressuscitação, visando reduzir a mortalidade por meio do reconhecimento precoce e tratamento da síndrome pós-parada cardíaca. A hipotermia terapêutica tem demonstrado melhora significativa da lesão neurológica e deve ser realizada em indivíduos comatosos pós-parada cardíaca. Para os médicos que trabalham na emergência ou unidade de terapia intensiva é de grande importância o aperfeiçoamento no tratamento desses pacientes por meio de treinamentos específicos, possibilitando maiores chances de sucesso e maior sobrevida.

Despite advances related to the prevention and treatment in the past few years, many lives are lost to cardiac arrest and cardiovascular events in general in Brazil every year. Basic Life Support involves cardiovascular emergency treatment mainly in the pre-hospital environment, with emphasis on the early recognition and delivery of cardiopulmonary resuscitation maneuvers focused on high-quality thoracic compressions and rapid defibrillation by means of the implementation of public access-to-defibrillation programs. These aspects are of the utmost importance and may make the difference on the patient's outcomes, such as on hospital survival with no permanent neurological damage. Early initiation of the Advanced Cardiology Life Support also plays an essential role by keeping the quality of thoracic compressions; adequate airway management; specific treatment for the different arrest rhythms; defibrillation; and assessment and treatment of the possible causes during all the assistance. More recently, emphasis has been given to post-resuscitation care, with the purpose of reducing mortality by means of early recognition and treatment of the post-cardiac arrest syndrome. Therapeutic hypothermia has provided significant improvement of neurological damage and should be performed in comatose individuals post-cardiac arrest. For physicians working in the emergency department or intensive care unit, it is extremely important to improve the treatment given to these patients by means of specific training, thus giving them the chance of higher success and of better survival rates.

Equipamento brasileiro de detecção gama intra-operatória para biópsia de linfonodo sentinela / Brazilian gamma detection device for sentinel lymph node biopsy

OBJETIVO: Testar a eficácia de equipamento de detecção gama intra-operatória (DGI) desenvolvido pelo IPEN (Brasil), em procedimentos de biópsia de linfonodo sentinela (BLS) no melanoma e no câncer de mama. MÉTODOS: Foram estudados 40 pacientes portadores de melanoma ou câncer de mama com indicação para realização de BLS.Todos pacientes foram submetidos à linfocintilografia e a BLS ocorreu entre 2 a 24 horas após a mesma. Concomitantemente à DGI, realizou-se o mapeamento linfático com corante vital. Foram feitas leituras com o equipamento convencional Neoprobe® 1500 e com o equipamento em teste (IPEN) dos valores de captação do sítio de injeção do radiofármaco, do LS in vivo e ex vivo e da captação de fundo. Foi registrado se o LS estava corado e se o cirurgião teve facilidade para encontrá-lo. Nos primeiros 20 pacientes utilizou-se o equipamento convencional e depois o de teste; nos outros 20, utilizou-se primeiro o equipamento em teste, com objetivo de verificar se o mesmo identificava primariamente o LS. RESULTADOS: Dos quarenta pacientes, 33 eram portadores de tumor de mama e sete de melanoma cutâneo; variação da idade: 21 a 68 anos (mediana= 46 anos); 35 mulheres e 5 homens. Em apenas um paciente o LS não foi encontrado, nem pela DGI nem pelo corante vital. Não houve diferença estatística entre as razões ex vivo/fundo obtidas com os dois equipamentos (p=0, 2583-ns). CONCLUSÃO: É possível realizar o procedimento de BLS com o equipamento brasileiro desenvolvido pelo IPEN, com facilidade e sem prejuízo para o paciente.

OBJECTIVE: To test the effectiveness of an intra-operative gamma detection Brazilian device (IPEN) on sentinel lymph node biopsy (SLNB) procedures. METHODS: Forty melanoma or breast cancer patients with indication for undergoing SLNB were studied. Lymphoscintigraphy was done 2 to 24 hours prior to surgery. Lymphatic mapping with vital dye and gamma detection were performed intraoperatively. For gamma detection Neoprobe ® 1500 was used followed by IPEN (equipment under test) in the first 20 patients and for the remaining half IPEN was used first to verify its ability to locate the sentinel node (SN). Measurements were taken from the radiopharmaceutical product injection site, from SN (in vivo and ex vivo) and from background. It was recorded if the SN was stained or not and if it was found easily by surgeon. RESULTS: There were 33 (82.5 percent) breast cancer and 7 (17.5 percent) melanoma patients. Ages varied from 21 to 68 year-old (median age of 46). Sex distribution was 35 (87.5 percent) women and 5 (12.5 percent) men. Sentinel node was found in all but one patient. There was no statistical difference between the reasons ex vivo/ background obtained with the measures of both equipments (p=0, 2583-ns). The SN was easily found by the surgeon with both devices. CONCLUSION: The SLNB was successfully performed using either equipment. It was possible to do SLNB with the Brazilian device developed by IPEN without prejudice for the patient.
