ABSTRACT
A síndrome do esmagamento é condição clínica potencialmente fatal se não for tratada prontamente. O choque hipovolêmico é a causa mais comum de morte nas primeiras 48 horas, seguida pela insuficiência renal consequente ao baixo fluxo glomerular e à obstrução tubular por mioglobina. O objetivo deste estudo é relatar um caso de trauma musculargrave que cursou para síndrome do esmagamento associado à síndrome compartimental, atendido no serviço de pronto-socorro do Hospital de Base do Distrito Federal, e mostrar as estratégias adequadas na condução clínica desse paciente em estado crítico.
Crush syndrome is often fatal if not treated promptly. Hypovolemic shock is the most common cause of death at the first 48 hours, followed by renal failure due to the low glomerular flow and tubular obstruction by myoglobin.The objective of this report is to present a case of muscle trauma that has evolved to a crush syndrome associated with compartment syndrome, attended at the emergency room of Hospital de Base do DF and to show appropriate strategies in the clinical management of this critically ill patient.
ABSTRACT
En el paciente hipotiroideo la creatinina sérica puede aumentar no solo por fallo renal, sino también por miopatía en presencia de función renal normal. Se reportan 2 pacientes representativos de sendos tipos de la clasificación aquí propuesta sobre la asociación disfunción tiroidea / creatinina sérica. El primer enfermo presenta aumento de la creatinina sérica secundario a miopatía hipotiroidea con función renal normal, tipo I, esta se puede complicar con rabdomiolisis y causar insuficiencia renal aguda en hipotiroideos no diagnosticada. El otro paciente con creatina sérica alta mejoró su función renal al tratarse su hipotiroidismo, tipo 2. Ocasionalmente, este ha permanecido oculto y al ser diagnosticado y tratado, se mejora la función renal. El hipotiroidismo cursa con hipercolesterolemia y si no se valora la función tiroidea y se administran estatinas, se empeora el daño muscular del paciente. Lo mismo ha sucedido con el uso de gemfibrozil en condiciones similares. El tercer tipo de daño renal relacionado con hipotiroidismo es la proteinuria en rango de síndrome nefrótico, vinculada con suspensión de la levotiroxina. Las biopsias muestran lesiones histológicas de diversas glomerulopatías, que mejoran con la administración de levotiroxina. En pacientes con tiroiditis de Hashimoto aparecen otras glomerulopatías que responden a los glucocorticoides...
In patients with hypothyroidism is possible to find an increased serum creatinine not only due to renalfailure but to myopathy in presence of normal renal function. Two patients, each representing 1 type of a proposed classification regarding thyroid dysfunction and abnormal creatinine are presented, in order to communicate thisrelationship, until now based on isolated reports. The first individual had an increased serum creatinine withnormal renal function due to hypothyroid myopathy (type 1). Rhabdomyolysis related to this myopathy is pointed as a cause of acute renal failure. The 2nd patient had an increased serum creatinine with abnormal kidney function (type 2),which improved when he became euthyroid after levothyroxine administration. The diagnosis of hypothyroidism is often missed in patients with altered renal function, if it becomes evident and is properly treated the renal function will improve. As isknown hypothyroidism causes hypercholesterolemia, if such patient unknowingly receives statins or gemfibrozil, severe rhabdomyolysis and renal falilure may occur, as reported inthe literature. The 3d category of the classification is the occurrence of nephrotic syndrome in hypothyroid patients who discontinue T4 treatment due to thyroid cancer for further studies or by patient non adherence, developingsignificant proteinuria few months later. Kidney biopsy lesions vary from membranous glomerulopathy tomembranoproliferative glomerulonephritis. These findingswill resolve with the administration of levothiroxine, without glucocorticoids. However patients with nephrotic syndrome related to Hashimoto thyroiditis will improve withglucocorticoids.
