I experienced a case of a congenital intramural cyst of the uterine fundus. On examination by light and electron microscope it was composed of a single layer of thin atrophied lining epithelium without secretory activity and was found to be derived from the paramesonephric duct. This case is presented with a brief review of the literature.

BACKGROUND: The purpose of this clinical study was to evaluate the Incentive Spirometry (IS) and Deep Breathing Exercises (DBE) to prevent postoperative pulmonary complications after abdominal surgery in patients over 60 years of age. METHODS: We prospectively randomized 90 patients into 1 of 3 groups: the control group (30 patients) received no respiratory treatment, the IS group (30 patients) was treated with incentive spirometry 4 times daily and DBE group (30 patients) carried out deep breathing exercises under supervision for 15 min 4 times daily. ABGA was taken at ward, PR (preop.room), RR (recovery room), POD1 day and POD2 day. Roentgenographic changes observed at 24 h. and 48 h. after surgery. Pulmonary complications were defined as the development of 3 or more of 6 new findings: cough, sputum, dyspnea, chest discomfort, temperature greater than 38oC, pulse rate more than 100 beats/min. RESULTS: PaO2 in the DBE group and IS group at PR were significantly increased than the values at ward, and the values of the PaO2 in the DBE group at RR and POD1 day, and those of IS group at PR and POD2 day were significant higher than those of the control group (p<0.05). The frequency of development of pulmonary complications (43.3% in the control group, 20% in the DBE group, 20% in the IS group) and roentgenographic changes were comparable in the 3 groups (26.7%, 16.7%, 20% respectively). The DBE group showed the different incidence of postoperative pulmonary complications between upper and lower abdominal surgery (upper: lower= 35.7: 6.3%). CONCLUSIONS: We concluded that DBE and IS were effective in preventing postoperative pulmonary complications after abdominal surgery and lower abdominal surgery causes lesser postoperative pulmonary complications than upper abdominal surgery.

Among the efficient cancer treatments, photodynamic therapy (PDT) is one of the therapies inducing rapid apoptosis of cancer cells while causing minimal damage to surrounding normal tissue. We studied the effect of PDT on the adenocarcinoma in BALB/-c mice of homograft model, and the following results were obtained. Apoptosis occurred up to 3 mm in depth from the surface in the first 1 hour after PDT applied, and subsequently the counts were increased in the deeper portion. A remarkable apoptosis observed up to 6 mm in depth shows that the light in use could not penetrate more than 6 mm of tissue. Tissue necrosis was identified in the deeper area of the tumor 6 hours later or thereafter. This necrosis seemed to occur as an indirect effect of vascular obstruction resulting from the damage of endothelial cells which was induced by selective collection of photosensitizer in the endothelial cells of newly forming vessels as well as in the cancer cells. These results indicate that the effective depth of PDT is greater than the depth of light penetration.

PURPOSE: To prove whether the arterioportal shunt, especially transvasal shunt is one of the cause of the hypovascular hepatocellular carcinoma. MATERIALS AND METHODS: We evaluated the early phase images of table incremental dynamic CT and hepatic angiography in 20 cases of hepatoceltular carcinomas with transvasal arterioportal shunt. RESULTS: In hepatic arteriography, 18 cases were hypovascular and the remained 2 cases showed hypervascular tumor staining than surrounding normal hepatic parenchyme. In the early phase dynamic CT, 18 cases were hypodense(including 4 cases of focal hyperdensity in hypodense background), one was isodense and remaining one was hyperdense. CONCLUSION: Arterioportal shunt, especially transvasal shunt may make originally hypervasular hepato-cellular carcinoma to hypovascular lesion in the early phase dynamic CT or hepatic arteriography. In attempt to differentiate hepatic masses by tumor vascularity in recently widely used table incremental dynamic CT, the vascular patterns of the mass should be considered by close evaluation of vascular pattern of the liver, such as morphology of perfusion abnormality and arterioportal shunt, etc.

Desmoid tumor is a type of fibromatosis usually arise in deep musculo-aponeurotic structures, primarily of the trunk and extremities. It is characterized by proliferation of fibroblastic tissue and does not metastasize but may be locally aggressive. Eventhough the surgical margin reveals clean, recurrence often occurs. To analyze the extent of the tumor and homodynamic characteristics exactly, we performed IV bolus CT. Desmoid tumors show peripheral rim enhancement on early phase scan and more strong, central enhancement on late phase IV bolus CT, which reflects abundant fibroblastic components of the tumor. We report two cases of pathologically confirmed desmoid tumor performed IV bolus CT.

Focal nodular hyperplasia is a benign hepatic tumor mainly composed of nodules of hepatocytes and Kupffer cells separated by fibrous septa. In general, it is difficult to differentiate focal nodular hyperplasia and hepatocellular carcinoma on ultrasonography, conventional CT(computerized tomography), and angiography. But IV bolus CT is of particular value in the diagnosis of focal nodular hyperplasia because it can divide enhanced CT into early and late phase and can characterize tumor vascularity and analyze any intratumoral elements. In our case, it was seen as a hypoechoic mass lesion on ultrasonograpl'hy and hyperdense mass lesion on early-phase IV bolus CF and isodense mass, lesion on late-phase IV bolus CT. On angiography, hypertrophy of the feeding artery and tumor staining were well visualized. The patient underwent operation and the mass was pathologically confirmed to a focal nodular hyperplasia. We report the first case of focal nodular hyperplasia on IV bolus CT in Korea.

Plaster of Paris is an effective ancillary treatment in the surgery of infected cavities in bone. It is well tolerated and spontaneously absorbed over the period of weeks to months, being replaced by bone of normal architecture. When the antibiotics incorporated into plaster of Paris, the antibiotics are capable of prolonged local release in bactericidal concentrations. Therefore it is proposed that antibiotics loaded plaster of Paris might be a simple adjuvant technique after good surgical debridement for the treatment of bone infection. The authors carried out an experiment to study the effect of plaster of Paris containing antibiotics for a prevention of experimental osteomyelitis, using 45 rats, which were divided into 3 groups. In the Group 1, a defect was made at the proximal metaphysis of the tibia, inoculated by Staphylococcus aureus sensitive to Cephradine and Tobramycin and then filled with plaster of Paris pellet. In the Group 2, a defect was filled with Cephradine loaded plaster of Paris pellet. In the Group 3, a defect was filled with Tobramycin loaded plaster of Paris pellet. Then we observed the healing process of the bone defect in the point of view of the gross findings, radiologic findings and histologic findings at 4th, 8th and 12th week after operation. The results of this study were as follows:l. In the control Group;all 30 cases were infected. 2. In the Group 2;only 4 of 30 cases were infected. 3. In the Group 3;all 30 cases were not infected. 4. The plaster of Paris filled into the defect was absorbed continuously and stimulated the new bone formation.

We studied the degenerative changes of acetabulum, examining the acetabular articular cartilage at weight bearing dome area from the hips of 25 avascular necrosis of femoral head cases. Histological- histochemical studies demonstrated 4 mild, 19 moderate and 2 severe grade of degenerative arthritic change. This has confirm that even in early stage of avascular necrosis of femoral head, there are degenerative arthritis in acetabular cartilage. This may influence the prognosis of bipolar hemiarthro- plasty in avascular necrosis of femoral head patient.

The purpose of this study is to evaluate the influence of the extent of involvement in the results of cementless THA in patients with idiopathic AVN of the femoral head. We reviewed 70 hips (52 patients) who had undergone cementless THA for idiopathic AVN of the femoral head. Anatomic femoral components were used in 43 hips and Harris Galante porous prosthesis were employed in 27 cases. The hips were classified according to International Classification (Association Research Circulation Osseous). The length of the follow-up period ranged from 3 to 5 years (average 53.5 months). Preoperative and postoperative clinical documentation and radiographs were evaluated. Statistical analysis was performed on the results of three analysis groups (Group A, comparison of results among Stage IIIA, IIIB, IIIC, and IV; Group B, between stage III and IV; Group C, between IIIA+IIIB and IIIC + IV). Of the 70 hips in the present study, there were 47 hips in stage III (IIIA, 15; IIIB, 19; IIIC, 13) and 23 hips in stage IV. The average postoperative Harris hip score at the time of study was 91.5 (Analysis Group C, p=.009). Femoral subsidence of more than 5 mm occurred in 5 hips (7.1%). Two hips were in Stage IIIC and three hips were in Stage IV (Group C, p=.024). The hips lower than -10 on Engh's index were present in one hip in Stage IIIC and three hips in Stage IV (Group C, p=.011). This study demonstrated that the clinical and radiological results of cementless THA were poor when the extent of involvement was greater or in the case of late stage subjects, particularly those above IIIC (p<05), with avascular necrosis of the femoral head.
