LTS is effective in the elimination and prevention of clinically intractable aspiration. The procedure is potentially reversible. However, the frequency of complications for both LTS and reversion surgery is significant.
Unsedated TNE is a feasible, well accepted, and efficient diagnostic tool for the screening of ESCC. The elevated rate of esophageal neoplasia strengthens the recommendations to screen patients with HNSCC. The yields of WLE and FICE were similar for ESCC detection.
CONTEXT: Kikuchi-Fujimoto disease (KFD) manifests in most cases as unilateral cervical lymphadenomegaly, with or without accompanying fever.The disease mainly affects young women and has a self-limited course. It is more common in oriental countries, with few reports of its occurrence in Brazil. KFD should be included in the differential diagnosis of suspected cases of viral infections, tuberculosis, reactive lymphadenitis, systemic lupus erythematosus and metastatic diseases. It can be histologically confused with lymphoma. The disease is benign and self-limiting and an excisional biopsy of an affected lymph node is necessary for diagnosis. There is no specific therapy. CASE REPORTS:This study reports on three cases of non-Asian female patients with KFD who were attended at our service between 2003 and 2006. A review of the literature was carried out, with a systematic search on this topic, with the aim of informing physicians about this entity that is manifested by cervical masses and fever.RESUMO CONTEXTO: A doença de Kikuchi-Fujimoto (DKF) se manifesta na maioria das vezes como linfadenomegalia cervical unilateral, que pode ser acompanhada de febre. Afeta principalmente mulheres jovens, com evolução autolimitada. A prevalência desta doença é mais comum no oriente, havendo poucos relatos de sua ocorrência em nosso meio. DKF deve ser incluída no diagnóstico diferencial de casos suspeitos de infecções por vírus, tuberculose, linfadenite reacional, lúpus eritematoso sistêmico e doença metastática. Histologicamente pode ser confundida com linfoma. A doença é de caráter benigno, auto-limitada, a biópsia excisional do linfonodo acometido é necessária para o diagnóstico e não há tratamento específico. RELATO DE CASOS:Este trabalho relata três casos de pacientes não asiáticas do sexo feminino com DKF, atendidas em nosso serviço entre 2003 e 2006, e faz revisão da literatura com uma busca sistematizada sobre o assunto, com o objetivo de informar os médicos sobre essa entidade que se manifesta com massa cervical e febre.
CONTEXT AND OBJECTIVE: Magnesium ion concentration is directly related and phosphorus ion concentration is inversely related to calcemia. The aim of this study was to evaluate the evolution of magnesium and phosphorus ion levels in patients undergoing thyroidectomy and correlate these with changes to calcium concentration. DESIGN AND SETTING:Prospective study at the Alpha Institute of Gastroenterology, Hospital das Clínicas, Universidade Federal de Minas Gerais. METHODS:The study included 333 patients, of both genders and mean age 45 ± 15 years, who underwent thyroidectomy between 2000 and 2005.Total calcium, phosphorus and magnesium were measured in the blood preoperatively and 24 and 48 hours postoperatively. Ionic changes were evaluated according to the presence or absence of postoperative hypocalcemia.RESULTS: There were statistically significant drops in blood phosphorus levels 24 and 48 hours after thyroidectomy, compared with preoperative values, in the patients without hypocalcemia. In the patients who developed hypocalcemia, there was a significant drop in plasma phosphorus on the first postoperative day and an increase (also statistically significant) on the second day, in relation to preoperative phosphorus levels. A significant drop in postoperative magnesium was also observed on the first and second days after thyroidectomy in the patients with hypocalcemia, in relation to preoperative levels. In the patients without hypocalcemia, the drop in magnesium was significant on the first day, but there was no difference on the second day.CONCLUSION: Despite the postoperative changes, neither magnesium nor phosphorus ion levels had any role in post-thyroidectomy calcemia. RESUMO CONTEXTO E OBJETIVO:A concentração do íon magnésio está diretamente e a do íon fósforo inversamente relacionada à calcemia. O objetivo foi avaliar a evolução das concentrações dos íons magnésio e fósforo nos pacientes submetidos a tireoidectomia, e relacioná-los com as alterações da concentração do cálcio. TIPO DE ESTUDO E LOCAL: Estudo prospectivo realizado no Instituto Alfa de Gastroenterologia, Hospital das Clínicas, Universidade Federal de MinasGerais. MÉTODOS:O estudo incluiu 333 pacientes de ambos os sexos, com média de idade de 45 ± 15 anos, submetidos a tireoidectomia no período de 2000 a 2005. Cálcio total, fósforo e magnésio foram dosados no pré-operatório e com 24 e 48 horas de pós-operatório. As alterações dos íons foram avaliadas de acordo com a presença ou ausência de hipocalcemia pós-operatória. RESULTADOS:Houve queda estatisticamente significativa dos níveis sanguíneos de fósforo 24 horas e 48 horas após a tireoidectomia em relação ao pré-operatório nos pacientes que não tiveram hipocalcemia. Quanto aos pacientes que evoluíram com hipocalcemia, houve queda significativa do fósforo plasmático no primeiro dia de pós-operatório e elevação, também estatisticamente significativa, no segundo dia em relação ao fósforo pré-operatório. Foi também observada queda significativa do magnésio pós-operatório em relação ao p...
