PURPOSE: To evaluate the usefulness of percutaneous catheter drainage (PCD) in patients who have abdominal abscesses or fluid collections. MATERIALS AND METHODS: We performed PCD for 165 abscesses and fluid collections in 148 patients. The follow-up periods in these patients ranged from 15 days to 42 months (mean, 274 days). The lesion sites were subphrenic space in 46 cases, liver in 33, perihepatic space in 20, pancreas or peirpancreatic space in 14, pelvic cavity in 13, and retroperitoneum in 13. We evaluated the success, failure, and recurrence rates, the causes of failure or recurrence, the mean duration of drainage, and the complications of PCD. RESULTS: Of the 165 cases, one hundred-fifty nine(96.5%) were successfully cured, Although a partial success could be achieved, 2(1.2%) cases were failed and 4(2.4%) were recurred. Multiloculation or fistula formation were the main causes of the unsullessful cases. The duration of drainage rainged from 2 to 605 days (mean, 1 days). Complications occured in 12 cases(7%) during or after procedures, which included fever and chill in 7, transgression of pleura in 2, bowel perforation in 2, and bleeding through catheter in 1. CONCLUSION: PCD is an effective and safe method for various abdominal abscesses or fluid collections.

Clear cell sarcoma (CCS), also called malignant melanoma of soft parts, is a rare malignant soft tissue tumor and is often associated with tendons or aponeuroses. Most of CCS involve extremities, especially lower extremities, but a tumor occurring in the trunk is rare. We report an extremely rare case of CCS originated in the upper thoracic back muscle. To our knowledge, this case is the second report of CCS of the back muscle.

It is well known that some inhalation anesthetics and ancillary drugs are metabolized in the liver. Since this fact was reported (Read, 1672: Dripps, 1977) the influence of different anesthetics on the liver has been of great interest up to date. The most cause of postoperative hepatic dysfunction seems to be acute viral hepatitis, but there are some other causes such as anesthetic damage and untoward reactions to the drugs used in the intraoperative or postoperative periods(Bahior & Davidson, 1967: Bruce, 1972). Halothane is usually a safe and effective inhalation anesthetic agent but on occation it has damaged the liver. Many papers have reported these untoward reactions, and then attention began to be paid to other anesthetic agents. The author selected random samples of 100 adult femal patients who had lower abdominal operations at Wonju Christian Hospital between May 1982 to August 1982. Their physical status was ASA class l & ll, liver function tests were within normal limits and they had no previous history of operation or liver disease. They were divided into five groups according to the anesthetic agent used(halothane, ethrane, ether, Thalsmonal neuroleptanesthesia and lidocaine epidural anesthesia). The liver function tests were performed before surgery, and on the 1st, 3rd, 5th, and 7th postoperative days. The results were as follows. 1) BUN, total protein, albumin, globulin and total cholesterol were not significantly changed. 2) The values of SGOT &SGPT were slightly increased elevated on the first postopday, and on the 3rd day after operation and then gradually decreased. On the 7th day after operation they had returned to the preoperative levels. The changes of the values were within normal limits. 3) Alkaline phosphatase, total bilirubin and direct bilirubin were not significantly influenced by the anesthetic agents. It is suggested that the influence of variable anesthetic agent on the liver is not significant, and that the changes of the liver function tests were minimal, and the values of the tests have usually returned to normal by the 7th day after operation.

8.Lumbar Radiculopathy Caused by Intraspinal Synovial Cyst: A Case Report.

A spinal synovial cyst is an uncommon lesion associated with degenerative spinal arthropathy. It can cause radicular symptoms and may masquerade clinically as other, more common entities. A 50-year-old female presented with an intraspinal synovial cyst at the L5-S1 level manifesting as lower back pain and right leg pain. The patient's clinical symptoms improved after surgical management. Intraspinal synovial cyst should be considered in the differential diagnosis of the patients presenting with acute radicular symptoms.

Clothing dermatitis is a rare disease. The distribution of the eruption coincides with the places on the skin where the garment fits most snugly. It is developed by the chemicals and the dyes rather than textile itself. We experienced 2 cases of clothing dermatitis, one of which was caused by formaldehyde in clothing.
