Percutaneous catheter drainage has been reported to bean effective method in the management of selectedpatients with abscess and fluid collection. Its high sucess rate and relatively low complications make theprocedure an alternative to surgery in the individual cases. During past two years percutaneous catheter dainagein 25 patients with intraabdominal abscesses and fluid collection was performed at the Department of Radiology,Yonsei Universtiy College of medicine. Here the technique and auathor's results were summarized; 1. The total 25patients who had percutaneous catheter drainage are 10 liver abscesses, 3 subphrenic, one subhepatic, 4 renal andperirenal, 2 pelvic, one psoas, one anterior pararenal fluid from acute pancreatitis, one pancreas pseudocyst and2 malignant tumor necrosis. 2. The modified Seldinger technique used for all cases of abscess and fluid draingeunder guidence of ultrasound scan. The used catheters were 10F. Pigtail and 14F. Malecot (Cook c/o) catheters. 3.The abscesses and fluid of 17 patients among 25 were cured by the percutaneous catheter drainage and 4 patientswere clinically improved. The catheter drainage was failed in 2 patients and 3 complications were developed. 4.The success rate of this procefure was 91.3%, failure rate was 8.7% and complication rate was 12%.

We retrospectively reviewed the MRI findings of 100 temporomandibular joints in 78 patients who had complained temporomandibular joint dysfunction. MRI findings were classified according to Wilke's staging criteria. And these findings were compared with arthrographic findings in 22 joints and surgical findings in 44 joints. According to Wilkes's staging. They were classified into 6 stages of abnormality: stage 0 (33 cases), stage I (19 cases), stage II (10 cases), stage III (18 cases), stage IV (6cases), stage V (14 cases). Among the 22 cases in which arthrography and MRI were done, both studies were well correlated in 10 joints. In 7 joints, MRI was superior to arthrography, which correctly demonstrated the meniscal displacement in 2 joints and . Meniscal deformity in 5 joints. In 5 joints, arthrography was superior to MR, which demonstrated the perforation (1 joint), adhesion (2 joint) and recapture of meniscus (2 joints). Compared with surgical findings, MRI correctly demonstrated the displacement of meniscus in all 44 joints. However, in case of the 10 meniscal perforation, MRI demonstrated the meniscal discontinuity in only 4 joints. Retrospective MR findings in 10 proven cases were the defect in posterior attachment in 4, far anterior meniscal displacement without recapture in 8m condylar spur in 4, and close bone to bone contact in 1. In conclusion, MRI as a primary Fiagnostic modality of temporomandibular joint derangment, is superior for the grading of displacement and deformity of meniscus but inferior for the evaluation of perforation, adhesion and recapture of meniscus to conventional arthrography. In case of the suspected meniscal perforation, arthrographic correlation is recommanded preoperatively.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.

The globus symptom is a condition in which a patient, often middle aged women, complains of a lump andchocking sensation in the throat, Functional disturbance of the cricopharyngeal muscle, rendering it incapable ofrelaxing during swallowing, has long been recognized as a cause of globus symptom and dysphagia. We wanted to findout how often and to what extent distrubed relaxation of the cricopharyngeal muscle can be seen in patients withglobus symptom with routine examination and video esophagogram. The results were as follows: 1. Male : femaleratio was 1:2.4. 2. Globus symptom was most frequent in the age group between 30-39 of female. 3. Organic lesionswere seen in 43.6%(24 Pts) of globus patients. 4. Cricopharyngeal muscle was visualized in 29.1%(16Pts), esophageal diverticulum in 3.6%(2 Pts) and degenerative spondylosis in 3.6%(2 Pts). 5. Incidence of visualizationof cricopharyngeal muscle were higher in male group (50%) than female one (20.5%). 6. Cricopharyngeal muscle wasmost frequently visualized on early swallowing phase(12/16 Pts).

PURPOSE: To evaluate the optical quality after laser in situ keratomileusis (LASIK) or serial photorefractive keratectomy (PRK) using a double-pass system and to follow the recovery of optical quality after laser vision correction. METHODS: This study measured the visual acuity, manifest refraction and optical quality before and one day, one week, one month, and three months after laser vision correction. Optical quality parameters including the modulation transfer function, Strehl ratio and intraocular scattering were evaluated with a double-pass system. RESULTS: This study included 51 eyes that underwent LASIK and 57 that underwent PRK. The optical quality three months post-surgery did not differ significantly between these laser vision correction techniques. Furthermore, the preoperative and postoperative optical quality did not differ significantly in either group. Optical quality recovered within one week after LASIK but took between one and three months to recover after PRK. The optical quality of patients in the PRK group seemed to recover slightly more slowly than their uncorrected distance visual acuity. CONCLUSIONS: Optical quality recovers to the preoperative level after laser vision correction, so laser vision correction is efficacious for correcting myopia. The double-pass system is a useful tool for clinical assessment of optical quality.

PURPOSE: To evaluate the specific findings of angiography for various causes of gastrointestinal bleeding. MATERIALS AND METHODS: We retrospectively analyzed 35 patients of gastrointestinal bleeding detected by angiography, between April 1987 and July 1993. There were 28 men and 7 women, 19 to 83 years old (mean, 47 years). Of these 35 cases of gastrointestinal bleedings, there were 12 gastric bleedings, 4 duodenal bleedings, 9 small intestinal bleeings, 6 ileocecal bleedings, and 4 large intestinal bleedings. RESULTS: Of 35 cases, we could diagnose the specific cause of bleeing in 13 patients (37%) by angiography. Of these 13 cases, there were 4 cases of gastric ulcers showing contrast pooling in ulcer crater, 5 cases of vascular malformations showing anomalous vascular mass with early dilated venous drainage, 2 cases of direct invasion of hepatocellular carcinoma showing invasion of hypervascular mass into small bowel, one case of pseudoaneurysm at gastroduodenal artery in a patient of acute pancreatitis, and one case of small intestinal lymphoma showing contrast pooling in a irregular dilated small intestinal lumen. CONCLUSION: in gastrointestinal bleeding, angiography is useful not only in detecting the bleeding site, but also for evaluating the specific causes such as gastric ulcers or vascular malformations.
