Terapia descongestiva como complemento a la cirugía de anastomosis linfáticovenosas y transferencia de linfonodos vascularizados: Una revisión de la literatura / Decongestive therapy as an adjunct to lymphatic-venous anastomosis surgery and vascularized lymph node transfer: A review of the literature

Resumen Introducción: El linfedema es una enfermedad inflamatoria crónica que afecta cerca de 250 millones de personas en el mundo. El tratamiento tradicional es la terapia descongestiva. Últimamente, existe la opción de complementar el tratamiento tradicional con procedimientos quirúrgicos fisiológicos como anastomosis linfáticovenosas y transferencia de linfonodos vascularizados. Sin embargo, la evidencia del uso de la terapia descongestiva en los cuidados pre y posoperatorios en estas cirugías es limitada. Objetivo: Evaluar el uso de terapia descongestiva como complemento a la cirugía de linfedema mediante anastomosis linfáticovenosas y transferencia de linfonodos vascularizados. Materiales y Método: Se realizó una revisión de la literatura en las siguientes bases de datos: Cochrane, Pubmed y Google académico, utilizando los siguientes términos mesh: "anastomosis, surgical", "lymphedema", "perioperative care", "microsurgery", "rehabilitation", "therapy", "lymph nodes", "bypass", "lymphedema and microsurgery". Se incluyó aquellos artículos que describían el uso de la terapia descongestiva en los cuidados pre- y posoperatorios. Resultados: Se identificó un total de 201 artículos y 12 fueron incluidos en el análisis. La evidencia reporta que las terapias más usadas en el cuidado pre- y posoperatorio son compresión, drenaje linfático manual y tratamientos personalizados. Sin embargo, la mayoría de los autores hace una descripción vaga de las terapias mencionadas. Discusión y Conclusión: La evidencia respecto al uso de terapia descongestiva como tratamiento complementario es débil. Los expertos recomiendan su uso, sin embargo, se necesitan futuras investigaciones que describan el uso de cada uno de sus componentes como complemento de procedimientos quirúrgicos fisiológicos para el manejo del linfedema.

Background: Lymphedema is a disease that affects about 250 million people around the world. The traditional treatment is decongestive therapy. In the past years, there is the option to complementing the traditional treatment with physiological surgical procedures such as lymphatic-venous anastomosis (LVA) and vascularized lymph node transfer (VLNT). However, the evidence for the use of decongestive therapy in pre- and post-operative care in these surgeries is limited. Aim: To evaluate the use of decongestive therapy as a complement to lymphedema surgery such a lymphatic-venous anastomosis and transfer of vascularized lymph nodes. Materials and Method: A literature review was carried out in the following databases: Cochrane, Pubmed and Academic Google, using the following mesh terms: "anastomosis, surgical", "lymphedema", "perioperative care", "microsurgery", "rehabilitation", "therapy", "lymph nodes","bypass", "lymphedema and microsurgery". "Those articles that described the use of decongestive therapy in pre- and post-operative care were included. Results: 201 articles were identified and 12 were included in the analysis. The evidence reports that the most used therapies in pre- and post-operative care are compression, manual lymphatic drainage and personalized treatments. However, most of the authors give a vague description of the mentioned therapies. Discussion and Conclusion: The evidence regarding the use of decongestive therapy as a complementary treatment is weak. Experts recommend its use; however, future research is needed to describe the use of each of its components as a complement to physiological surgical procedures for the management of lymphedema.

Utility of a low-iodide diet in (131)I whole body scanning of patients with differentiated thyroid cancer.

INTRODUCTION: (131)I whole body scanning (WBS) is useful in the follow-up of patients with differentiated thyroid carcinoma (DTC). The need to follow a low-iodide diet (LID) to optimize WBS is widely recognized but there are few reports that justify this practice. The aim of this study was to assess levels of urinary iodide in patients who underwent WBS in our service and the possible impact of some changes to the diet on these levels. PATIENTS AND METHOD: Between January 2004 and December 2005, we measured iodide levels in 12-h urine samples by paired-ion-reversed-phase HPLC with electrochemical detection (sensitivity, 0.1 µg/dl) in 371 patients with DTC referred to our service for ablation or follow-up. The patients were divided into 2 groups: patients on hormone withdrawal and strict LID (group A) and those on hormone withdrawal and generic LID (group B). Urinary iodide excretion below 10 µg/dl was considered low. Data were analyzed by ANOVA and χ(2) tests. RESULTS: The mean±standard deviation urinary iodide excretion was 4.3±3 µg/dl in group A and 5.8±3.2 µg/dl in group B. The mean urinary iodide excretion in A group was significantly lower than that in group B (p<0.05). CONCLUSIONS: Following a strict LID significantly decreased urinary iodide excretion in patients undergoing WBS.

Enfermedad tiroidea subclínica en la población anciana sana institucionalizada / Subclinical thyroid disease in institutionalised healthy geriatric population

FUNDAMENTO: Determinar la prevalencia de enfermedad tiroidea subclínica en población anciana sana institucionalizada. PACIENTES Y MÉTODO: A 242 ancianos sanos, residentes en centros públicos andaluces, se les determinó la hormona estimuladora del tiroides (TSH), la tiroxina (T4) libre y los anticuerpos antitiroideos. RESULTADOS: Se halló una prevalencia de hipotiroidismo subclínico del 3,71 por ciento, de hipotiroidismo clínico del 1,65 por ciento de hipertiroidismo subclínico del 0,82 por ciento y de enfermedad autoinmune del 10,33 por ciento. CONCLUSIONES: En la población anciana sana institucionalizada, existe un alto índice de disfunción tiroidea no detectada. Ello justificaría un cribado hormonal para su diagnóstico (AU)
