Multilocular cystic renal cell carcinoma appears to be a distinct and rare subtype of renal cell carcinoma with characteristic gross and microscopic features. Multilocular cystic renal cell carcinoma should be separated from multilocular cyst, multilocular cystic nephroma, and renal cell carcinoma with cystic degeneration. We present a case of multilocular cystic renal cell carcinoma. A 61-year-old man presented with right flank pain for 4 years. The computerized tomography revealed multilocular cystic mass in the upper pole of right kidney. The cystic mass measured 4.5x4 cm. The cyst was multilocular and locules not communicated with each other. The solid area was not present. Microscopically, the locules were lined by flat or cuboidal neoplastic clear cells. The clear cells were focally aggregated in the septa. The nephron was not present in the septa.

Double contrast arthrography has been widely accepted as a method to diagnose the internal derangement of the knee. It is a safe and technically simple procedure permitting accurate diagnosis of lesions of the menisci. In 20 cases operated upon, with the diagnosis of internal derangement of the knee, we performed double contrast arthrography before surgery. We analysed the cases concerning the diagnostic accuracy of arthrography, its clinical significance and discrepancies between arthrographic findings and postoperative lesions. The results were as follows: 1. The cases consisted of 16 cases of meniscal lesion, 4 cases of ligamentous lesion and 3 cases of loose body. 2. In the meniscal lesions, 14 of the 16 cases (87.5%) were diagnosed accurately by arthrography, Therefore arthrography was more useful in diagnosing meniscal lesions as compared with clincal symptoms (69%). 3. In cases of ligamentous lesions arthrography was not significant-ly helfpful, in contrast clinical signs afforded important clues. 4. We encountered 1 case of false positive and 1 case of false negative.

BACKGROUND: In patients with medial orbital wall fracture, predicting the correlation between the degree of enophthalmos and the extent of fracture is essential for deciding on surgical treatment. We conducted this retrospective study to identify the correlation between the two parameters. METHODS: We quantitatively analyzed the correlation between the area of the bone defect and the degree of enophthalmos on computed tomography scans in 81 patients with medial orbital wall fracture who had been left untreated for more than six months. RESULTS: There was a significant linear positive correlation between the area of the medial orbital wall fracture and the degree of enophthalmos with a formula of E=0.705A+0.061 (E, the degree of enophthalmos; A, the area of bone defect) (Pearson's correlation coefficient, 0.812) (P<0.05). In addition, that there were no cases in which the degree of enophthalmos was greater than 2 mm when the area of the medial orbital wall fracture was smaller than 1.90 cm2. CONCLUSIONS: Our results indicate not only that 2 mm of enophthalmos corresponds to a bone defect area of approximately 2.75 cm2 in patients with medial orbital wall fracture but also that the degree of enophthalmos could be quantitatively predicted based on the area of the bone defect even more than six months after trauma.

Pulmonary sequestration is an abnormal lung tissue that does not communicate with tracheobronchial tree, and that receives blood supply from anomalous arteries. Pulmonary sequestration is divided into two anatomical forms, intralobar and extralobar. Extralobar pulmonary sequestration is usually located between the diaphragm and the lower lobe and has systemic arterial supply and venous drainage, and most patients are diagnosed in their infancy. We report an extralobar pulmonary sequestration located between the right upper lobe and the lower lobe in a 48-year-old female adult, which has anomalous blood supply from the right pulmonary artery and venous drainage directly into the left atrium.

Dehydroevodiamine (DHED) is one of the bioactive components of the Chinese herbal medicine Wu-chu-yu-tang that has been shown to produce various pharmacological effects. In the present study, we investigated the pharmacokinetics of DHED after intravenous administration of two doses (2.5 and 5 mg/kg) in anesthetized rats. The plasma concentration of DHED was measured by reverse-phase high-performance liquid chromatography with UV detection. The mean area under the curve of the time-concentration profile was 21.9 and 53.9 microgram-min/ml after the 2.5- and 5-mg/kg doses, respectively, and the volume of distribution was 1584.9 and 1580.6 ml following 2.5- and 5-mg/kg doses, respectively. Plasma concentration profiles versus time were compatible with a two-compartment model and first-order kinetics. The terminal elimination half-life was 91.8+/-16.6 min and 78.7+/-11.9 min in the dose of 2.5 and 5 mg/kg, respectively. This is the first report to study the pharmacokinetics of DHED in animals.

Pedicled omentoplasty is effective in thoracic surgery, but it is associated with several postoperative complications. A case of diaphragmatic hernia as a complication of pedicled omentoplasty in a 65-year-old male is reported. Because aortoesophageal fistula occurred three months after the patch aortoplasty for mycotic aneurysm of descending thoracic aorta, he underwent ascending thoracic aorta to abdominal aorta bypass surgery with resection of thoracic aortic aneurysm and esophagorrhaphy with wrapping of the esophageal suture line and the stumps of aorta with pedicled omental flap. Three years after the operation, herniation of the stomach developed. The pedicled omental flap was ligated and divided, and the diaphragm defect was repaired.

Keloids are benign fibrcus growths which extend beyond the original wound and rarely regress. Available methods of treatment include surgical excision, radiotherapy, intralesional steroid injection, cryotherapy, systemie. chemotherapy, zinc tape strapping, pressure, silicon gel and combined therapy. Postoperative irradiation is a useful and effective method of eradication or prevent.ion of keloid. We describe two cases of the prevention of keloids associated with postoperative irradiation.
