Tibial nerve entrapment by a Baker cyst: case report.

We report a rare case of degenerative joint disease of both knees, complicated by a Baker cyst. Our emphasis is on the role of electromyography and electrodiagnosis in the localization of this nerve entrapment syndrome. The patient presented with pain and swelling; venography revealed deep venous thrombosis of the right calf, including the popliteal and proximal superficial femoral vessels. The patient responded well to bed rest, analgesics, intravenous heparin and subsequent Coumadin anticoagulation, and was discharged two weeks later. Five weeks after onset of these acute problems, nerve conduction studies were done, leading to a diagnosis of Baker cyst with nerve entrapment. He responded well to knee joint aspiration and intraarticular prednisolone injection. Some evidence of improvement in the flexor hallicus longus muscle was detected at three-month follow-up.

Urinary output and incidence of acute urinary tract infection in patients with indwelling bladder catheters.

This study was designed to test the hypothesis that high urinary output in patients with an indwelling bladder catheter tends to protect the patients from acute urinary tract infection. Thirty-five cases of acute spinal cord injury were analyzed for average daily urine volume and frequency of acute urinary infection (defined as oral temperature above 101 F and requiring treatment for the infection). The study period encompassed the time from entry into the Rehabilitation Unit until a definitive effort was made to remove the catheter, a mean of 59 days. Twenty-six patients developed acute urinary infections while nine did not. Mean 24-hour urine output in the two groups was 2530 cc and 2540 cc, respectively. The only difference which could be found was a significant decrease in urinary output in the symptomatic group during the seven days preceding onset of acute infection.
