Resumo Angiomiolipomas (AMLs) são tumores benignos raros derivados do tecido mesenquimal, compostos em graus variados de tecido adiposo, muscular e de vasos sanguíneos. Os AMLs renais (AMLRs) resultam de um evento esporádico e, na maioria dos casos, o diagnóstico costuma ser fortuito, mas quadros de hemorragia e choque podem estar presentes. Durante a gestação, os AMLs podem aumentar de tamanho e romper, provavelmente pela altaexpressãodereceptoreshormonais,epeloaumentodacirculaçãomaternaedapressão abdominal.

Abstract Angiomyolipomas (AMLs) are rare benign tumors derived from mesenchymal tissue and composed of varying degrees of adipose tissue, muscle and blood vessels. Renal AMLs (RAMLs) are the result of a sporadic event, and, in most of cases, the diagnosis is usually incidental, but hemorrhage and shock may be present. During pregnancy, the size of AMLs may increase and they may rupture, probably due to the high expression of hormone receptors, and the increase in maternal circulation and abdominal pressure. The authors present a case of a woman with ruptured RAML submitted to urgent endovascular treatment four days after giving birth by cesarean section.

Abstract Purpose: To evaluate the influence tramadol on functional recovery of acute spinal cord injury in rats. Methods: Ten rats were divided into two groups (n = 5). All animals were submitted by a laminectomy and spinal cord injury at eighth thoracic vertebra. In control group, the rats didn’t receive any analgesic. In tramadol group, the rats received tramadol 4mg/Kg at 12/12h until 5 days by subcutaneous. Animals were following by fourteen days. Was evaluated the Basso, Beattie, Bresnahan scale (locomotor evaluation) and Rat Grimace Scale (pain evaluation) at four periods. Results: There no difference between the groups in locomotor evaluation in all periods evaluated (p>0.05) and in both groups there was a partial recover of function. The tramadol group show a lower pain levels at the first, third and seventh postoperatively days when comparing to the control group. Conclusion: The tramadol as an analgesic agent don’t influence on functional recovery of acute spinal cord injury in rats
