Tamoxifen is a nonsteroidal triphenylethylene delivative that has been widely used in the treatment of breast cancer. tamoxifen is indicated for the adjuvant treatment of breast cancer in women following total mastectomy or segmental mastectomy, breast irradiation and chemotherapy. tamoxifen has been shown to have significant benificial effect in the treatment of breast cancer patient as hormonal therapy. However ,there is mounting evidence that tamoxifen may affect other hormon sensitive organs, including the uterus and ovaries. An increased risk of endometrial polyps, endometrial hyperplasia and adenocarcinoma has been reported in tamoxifen treated women. We have met cases of endometrial polyp and endocervical polyp which were associated with tamoxifen use, after modified radical mastectomy for infilterating ductal carcinoma of breast . So we report these cases with the brief review of literatures.

Three cases who were successfully treated for cardiac injuries by open thoracotomy were reported. The range of the ages of the patients was 3rd decade. Two of the 3 were males with blunt injuries by motor vehicle accident and one was male with stab wound by knife. In the case of blunt injuries, the right atrium was involved in one case and the right and left atrium were involved in the other. The site of stab wound was the right atrium. There were two cases with the pre-operative diagnosis of cardiac injuries and they were blunt injuries. The case of stab wound was not diagnosed pre-operatively. All cases were treated with open thoracotomy-one posterolateral thoracotomy, one median sternotomy and one Clam shell incision. All of them had an uneventfull post-operative course.

A fracture of the affected extremity in patients with Klippel–Trenaunay–Weber syndrome can be fatal due to massive bleeding and show poor results. A 42-year-old male presented with an old fracture of the right femoral shaft with metal failure. We planned an operation to remove the previously fixed plate and to perform re-fixation using an intra-medullary nail. Preoperative angiography was performed and the arteriovenous malformations were embolized in order to reduce the risk of bleeding. After angiography, the previously fixed plate was removed.After the operation, a second angiography was performed immediately and the venous malformation was embolized. One week after the first operation, a second operation was performed in order to reduce the fracture and to perform re-fixation using an intramedullary nail. The patient is being followed without major complication over a period of seven years after surgery. We recommend careful planning of preoperative and postoperative angiography and embolization in order to reduce the risk of bleeding in patients with Klippel–Trenaunay–Weber syndrome.

Endoscopic sphincterotomy(EST) is now an established therapeutic procedure for various disorder of the pailla of Vater, the biliary tract, and the pancreas. From November 1992 to September l993, 123 cases of E.S.T were performed in our hospital. The success rate of EST was 97.8%, and choledocholithiasis was the indication for EST in 63. 4% of cases. Among 78 cases of choledocholithiasis, 47 cases were presence of gall bladder with stone (16 cases) or without stone (31 cases), especially 46 cases were assisted with needle type papillotome and 23 cases were assisted with guidewire. EST hae relatively low complications and is the therapy of choice for choledocholithiasis and various diisease of biliary tract. Guidewire assisted stanard papillotome probable reduce the use of needle type papillotome in the difficult cases that EST with pull type papillotome was impossible.
