Question: Abstract: Forty-three patients with renal-cell carcinoma underwent treatment for spinal cord compression over a 7-year period. Of these, 32 patients underwent surgery, while 11 patients underwent radiation alone. Before operation, 25 patients had relapsed following prior radiation, while seven others received postoperative radiation. A more aggressive surgical approach, tailored to the site of compression within the spinal canal, was used with the majority undergoing gross total tumor resection by an anterior approach. Immediate stability of the spine was achieved with methyl-methacrylate reconstruction of the resected segments. Preoperative spinal angiography with embolization of hypervascular tumors was carried out in eight patients. Patient parameters in the surgical and irradiated groups were comparable, except that a greater proportion of the radiation alone group had more than one organ system involved (64% v 44%). The median survival of the surgically treated patients was 13 months, compared with 3 months for those treated by radiation alone. In addition, a greater proportion of the surgically treated patients were benefitted neurologically (70%) compared with those treated by radiation (45%). With the development of effective surgical treatment for spinal metastases, early consideration for surgical treatment (before radiation) should be considered in selected patients. Preoperative spinal angiography and embolization are recommended whenever feasible to minimize intraoperative blood loss.

Answer: Surgical treatment of spinal cord compression in kidney cancer.

Question: Abstract: Eosinophiluria is considered a useful marker of drug-induced acute interstitial nephritis. However, recognition of eosinophiluria by Wright's staining is technically difficult, and the spectrum of disorders causing eosinophiluria is not completely defined. We have adapted Hansel's stain for the examination of urinary sediment. Whereas there was a variable uptake of Wright's stain by eosinophils in the urine, such eosinophils were readily recognized with Hansel's stain by the presence of bright red granules. The prevalence of eosinophiluria in acute interstitial nephritis was 10 of 11 patients, in acute tubular necrosis none of 30, in acute pyelonephritis none of 10, in acute cystitis 1 of 15, in postinfectious glomerulonephritis 1 of 6, in rapidly progressive glomerulonephritis 4 of 10, and in acute prostatitis 6 of 10. Eosinophiluria in acute interstitial nephritis was demonstrated by Hansel's stain in 10 of 11 patients but by Wright's stain in only 2 of 11 patients. We conclude that Hansel's stain substantially improves the recognition of eosinophiluria as compared with Wright's stain. Eosinophiluria is useful in distinguishing acute interstitial nephritis from acute tubular necrosis. The clinical spectrum of eosinophiluria also includes rapidly progressive glomerulonephritis, acute prostatitis, and occasionally, acute cystitis or postinfectious glomerulonephritis.

Answer: Eosinophiluria--a new method of detection and definition of the clinical spectrum.

Question: Abstract: Male Sprague-Dawley rats were maintained on high protein (60%), normal protein (20%), low protein (5%), or no protein (0%) diets for two or four weeks prior to 45 minutes of renal ischemia induced by renal pedicle clamping. Most (93%) of the rats on the high protein diet died within three days following renal ischemia. In addition, 69% of the rats on normal protein diets also died, most before the fourth day following ischemic insult. In contrast, 88% of the rats on the low protein diet lived, although some exhibited elevated serum creatinine levels for up to one to two weeks following ischemia. Finally, all of the rats on no protein diets lived, and most (75%) exhibited normal serum creatinine levels by the fourth day following ischemia. Shifting the diets of high protein and normal protein adapted rats to no protein diets immediately following ischemia did not improve postischemic survival. Also, changing the diets of no protein adapted rats to high protein diets immediately following ischemia did not significantly affect postischemic recovery. When rats were maintained on no protein diets for shorter periods of time prior to ischemia, it was found that approximately a week on this diet is necessary to provide maximum protection from postischemic acute renal failure. These findings demonstrate a dramatic effect of dietary protein prior to ischemic induced acute renal failure, and suggests that preoperative dietary protein intake should be an important consideration in those situations which are predisposed to postoperative acute renal failure.
Which is the apt title for the abstract? option1: Dietary protein prior to renal ischemia dramatically affects postischemic kidney function. option2: Febrile seizures: a protocol for emergency management.

Answer:
Dietary protein prior to renal ischemia dramatically affects postischemic kidney function.
