1.Retroperitoneal Teratoma: A Report of A Case.
Korean Journal of Urology 1962;3(1):77-80
A case of retroperitoneal teratoma, found in a ten month old female infant was reported. Twenty four hours after the direct retroperitoneal air insufflation, a retrograde pyelography was performed using B.B. 16F. cytoscope. These two studies were essential to make preoperative diagnosis. Review of retroperitoneal tumor was also added.

Authors reviewed 28 cases of displaced acetabular fracture treated operatively from Februay 1991 to January 1996 and followed up more than 1 year. The clinical results were retrospectively analyzed with consideration of surgical problems and complications. The results were as follows; 1. According to Letournels classification, we had 16 elementary fractures(57%) and 12 associated fractures(43%). 2. Kocher-Langenbeck approach in 16 cases, ilioinguinal in 9 cases, extended iliofemoral 2 cases and combined approach in 1 case were used. 3. The devices for internal fixation were as follows: screw only in 12 cases(elementary fracture 9cases, associated fracture 3 cases), plate and screw in 16 cases(elementary fracture 7 cases, as-sociated fracture 9 cases). 4. There were complications such as 3 degenerative arthritis, 2 superficial wound infection, 1 iatrog-enic sciatic nerve palsy and 1 avascular necrosis of femoral head and no postoperative heterotro-phic ossification. 5. Satisfactory reduction by radiologic criteria was gained in 23 cases(82%). Satisfactory results by clinical criteria(by dAubigne & Postels) was gained in 21 cases(75%). Only 2 patient with a satisfactory radiologic reduction was clinically unsatisfactory. It seems that the satisfactory operative reduction of the fracture is the factor that correlates best with a satisfact-ory clinical result.

Venous thrombosis is uncommon in young individuals. Hypereosinophilia is a rare cause of thrombosis that usually involves the heart and small vessels like retinal vessels. We report a case of massive deep vein thrombosis that developed in a young patient with hypereosinophilia who was successfully treated with continuous local infusion of urokinase.

Background:
The anti-oxidative, anti-inflammatory, and anti-apoptotic effects of erythropoietin may provide neuroprotective effects. Erythropoietin also modulates autophagy signaling that may play a role in anesthesia-induced neurotoxicity (AIN). Herein, we investigated whether AIN can be attenuated by the neuroprotective effect of erythropoietin in the Caenorhabditis elegans (C. elegans).
Methods:
Synchronized worms were divided into the control, Iso, EPO, and EPO-Iso groups. The chemotaxis index (CI) was evaluated when they reached the young adult stage. The lgg-1::GFP-positive puncta per seam cell were used to determine the autophagic events. The erythropoietin-mediated pathway of autophagy was determined by measuring the genetic expression level of let-363, bec-1, atg-7, atg-5, and lgg-3.
Results:
Increased lgg-1::GFP puncta were observed in the Iso, EPO, and EPO-Iso groups. In the Iso group, only the let-363 level decreased significantly as compared to that in the control group (P = 0.009). bec-1 (P < 0.001), atg-5 (P = 0.012), and lgg-3 (P < 0.001) were expressed significantly more in the EPO-Iso group than in the Iso groups. Repeated isoflurane exposure during development decreased the CI. Erythropoietin could restore the decreased CI by isoflurane significantly in the EPO-Iso group.
Conclusions
Erythropoietin showed neuroprotective effects against AIN and modulated the autophagic pathway in C. elegans. This experimental evidence of erythropoietin-related neuroprotection against AIN may be correlated with the induced autophagic degradation process that was sufficient for handling enhanced autophagy induction in erythropoietin-treated worms.

STUDY DESIGN: Review of the literature. OBJECTIVES: To present updated information on percutaneous vertebral augmentation (PVA) for osteoporotic spinal fractures (OSFs). SUMMARY OF LITERATURE REVIEW: Vertebroplasty and kyphoplasty have been used to treat osteoporotic spinal fractures for many years. A recent meta-analysis provides strong evidence in favor of cement augmentation in the treatment of symptomatic vertebral compression fractures. MATERIALS AND METHODS: Review of the relevant literature. RESULTS: A meta-analysis showed greater pain relief, functional recovery, and improvement in quality of life with cement augmentation compared with control subjects. CONCLUSIONS: Percutaneous vertebral augmentation of osteoporotic spinal fractures results in shorter hospital stays, reduced incidence of complications, and more rapid return of functional independence.

Cystic lymphangioma of the broad ligament is very rare benign cystic lesion. They rarely present in adult life. We present the case of a 37-year-old female with a history of chronic recurrent left lower abdominal dull pain over a period of several months. Clinical presentation of these tumors varies greatly from an asymptomatic mass to serious complications. The therapy of choice is a complete excision, unless vital structures were involved. Once excised, the prognosis is excellent. Our patient had complete excision of her lesion with a good outcome.

To examine the relationship between gastric ulcer and gastric cancer, we investigated petients with gastric ulcer diagnosed from 1986 to l993. We reviewed the endoscopic reports and films of patients with gastric ulcer retrospectively. We excluded the patients who was diagnosed as gastric cancer in two years follow-up. The results were as follaws; 1) During follow-up of the original cohort, there were 5 patients(0.5~%) in whom gastric cancer developed at the same site initially diagnosed as gastric ulcer. The gross type of the lesion was early gastric cancer in two and advanced gastric cancer in three patients 2) The time interval between the initial diagnosis of gastric ulcer and cancer development was from 31 months to 70 months (average 51 months). 3) At the initial examination of 5 gastric cancer patients, the diagnosis was active gastric ulcer in four, multiple gastric ulcer in one, and linear gastrie ulcer in one patient. Characteristic endoscopic findjngs were gastric ulcer with clubbing mucosal folds in three and gastric ulcer with bleeding in one patient. 4) During the follow-up period, endoscopicailly and histologically healing of gastric uleer was observed in one patient and histologic finding showed chronic superficial gastritits with intestinal metaplasia. These results suggest that gastric ulcers rarely progress to gastric cancer. However if the endoscopic findings are suspicious for malignancy, then follow-up endoscopy until complete healing should be done.

Multiple endocrine neoplasia type 1 (MEN1) is a rare inherited disorder caused by mutations in the MEN1 gene on chromosome 1. Clinical diagnostic criteria for MEN1 include the presence of two or more endocrine tumors such as pituitary, parathyroid, and pancreatic islet tumors. Treatment is needed for tumors accompanied by symptoms or having malignant potential. Malignant neuroendocrine tumors (NETs) are the major cause of MEN1-related death, and pancreatic NETs account for 30-80% of MEN1 cases. Surgery is the mainstay curative treatment, and endoscopic intervention is a treatment option when patients are poor candidates for surgery. A 33-year old female patient with MEN1 was treated via endoscopic ultrasonography-guided ethanol injection for a pancreatic NET.
