Vitamin C interferes with assays involving the redox-reaction. However, the interference of Vitamin C with electrolytes has not been reported. In the present case, we describe a 61-year-old lady with severe electrolyte abnormalities after administration of high doses of vitamin C. This patient, who had terminal colon cancer, presented to hospital with anuria. Her electrolytes were extremely abnormal (determined on the Beckman Synchron LX20): serum sodium 200 mmol/L, potassium 7.0 mmol/L, and chloride 50 mmol/L. Repeated measurements showed similar abnormalities. However, these critical abnormalities did not fit her clinical picture, as she was alert with normal vital signs. One of the specimens was also run on both the ABL700 and the Bayer644 analyzers, and the electrolytes appeared normal. Pooled serum from healthy individuals to which various amounts of vitamin C was added then was analyzed on Beckman Synchron LX20 for electrolytes, demonstrating the interference of vitamin C consistent with the initial finding. Thus, we eventually figured out that the aberrant results were due to the vitamin C caused analytical interference.

A 58-year-old man was referred to our hospital with high fever and anuria. Since undergoing a total pelvic exenteration due to bladder-invasive sigmoid colon cancer, urinary tract infections had frequently occurred. We treated with the construction of a bilateral percutaneous nephrostomy (PCN), and chemotherapy. Although we replaced the PCN with a single J ureteral catheter after an improvement of infection, urinary infection recurred because of an obstruction of the catheter. Urological examinations showed that an ileal conduit-ureteral reflux caused by kinking of the ileal loop was the reason why frequent pyelonephritis occurred. We decided to resect the proximal segment to improve conduit-ureteral reflux for the resistant pyelonephritis. After the surgery, the excretory urogram showed improvement and the urinary retention at the ileal conduit disappeared. Three years after the operation, renal function has been stable without episodes of pyelonephritis. Here we report a case of open repair surgery of an ileal conduit in a patient with severe urinary infection.

Tumor lysis syndrome (TLS) is a potentially life-threatening complication of chemotherapy. It usually occurs in rapidly proliferating hematological malignancies. TLS is deemed spontaneous (STLS) when it occurs prior to any cytotoxic or definite treatment. STLS is extremely rare in solid tumors. Here, we report a rare case of fatal STLS in a 47-year-old woman diagnosed with metastatic colon cancer. The patient developed acute renal failure with anuria, electrolyte disturbances, and metabolic acidosis before initiating chemotherapy. Despite appropriate management of TLS, including renal replacement therapy, she died within a few days from multiorgan failure. Only few other case reports of STLS associated with colon cancer have been reported in the literature.
