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.Universidade Anhembi MorumbiUniversidade Federal de São Paulo (UNIFESP)Universdidade Cidade de São PauloUNIFESP, EPMSciEL

A biópsia de linfonodo sentinela não deve ser recomendada para pacientes portadores de melanoma espesso Sentinel node biopsy should not be recommended for patients with thick melanoma

OBJETIVO: verificar se há alguma relação entre o estado histopatológico do linfonodo sentinela, a recorrência e a mortalidade decorrente do melanoma espesso em pacientes submetidos à BLS ao longo de um seguimento significante. MÉTODOS: Oitenta e seis pacientes portadores de melanoma espesso submetidos à BLS foram selecionados de um banco de dados prospectivo. A linfocintilografia, o mapeamento linfático e a detecção gama intraoperatória foram realizados em todos pacientes. O linfonodo sentinela (LS) foi analisado por HE e por imunoistoquímica. Linfadenectomia total foi indicada para os pacientes com LS positivo. O estado histopatológico do LS foi relacionado à taxa de recorrência e de mortalidade por melanoma. RESULTADOS: Cento e sessenta e seis LS foram retirados dos 86 pacientes. As idades variaram de 18 a 73 anos. Havia 47 mulheres e 39 homens. Micrometástases foram encontradas em 44 pacientes. Quarenta e dois pacientes foram submetidos à linfadenectomia total. Sete pacientes tiveram outro linfonodo positivo. Entre os 44 pacientes com LS positivo houve 20 recorrências e 15 mortes. Houve 18 recidivas e 12 mortes no grupo de LS negativo. A espessura de Breslow não apresentou correlação com o estado histopatológico do LS. O estado histopatológico do LS não interferiu nas taxas de recorrência e de mortalidade (teste de Fisher, p=1.00). A mediana de seguimento foi 69 meses. CONCLUSÃO: Considerando a falta de evidência de benefício, a BLS não deve ser indicada para pacientes com melanoma espesso fora de estudos clínicos.<br>OBJECTIVE: To ascertain whether there is any relationship between the state of the sentinel lymph node histopathology, recurrence and mortality from thick melanoma in patients undergoing SLNB over a long follow-up. METHODS: Eighty-six patients with thick melanoma undergoing SLNB were selected from a prospective database. Lymphoscintigraphy, lymphatic mapping and intraoperative gamma probe detection were performed in all patients. The sentinel lymph node (SLN) was analyzed by HE and immunohistochemistry. Complete lymphadenectomy was indicated for patients with positive sentinel node. The histopathological SLN status was related to the rate of recurrence and mortality from melanoma. RESULTS: One hundred and sixty-six SLNs were taken from the 86 patients. Ages ranged from 18 to 73 years. There were 47 women and 39 men. Micrometastases were found in 44 patients. Forty-two patients underwent complete lymphadenectomy. Seven other patients had positive lymph node. Among the 44 patients with positive sentinel node, there were 20 recurrences and 15 deaths. There were 18 recurrences and 12 deaths in the group with negative SLN. The Breslow thickness was not correlated with the histopathological SLN status. The histopathological SLN status did not affect the rates of recurrence and mortality (Fisher test, p = 1.00). The median follow-up was 69 months. CONCLUSION: Considering the lack of evidence of benefit, SLNB should not be indicated for patients with thick melanoma outside of clinical studies
