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.

Alterations in the expression of genes that control the cell cycle may be of critical importance in tumorigenesis and malignant transformation. The major regulatory events leading to cell proliferation occur in Gl phase of cell cycle, and the deregulated expression of Gl cyclins is related to oncogenesis. Cyclins Dl and E play important roles in the progression of cell through Gl phase of the cell cycle. Amplification and/or overexpression of the cyclin Dl gene and aberrant expression of cyclin E has been described in various forms of human cancer. However, the role of cyclins Dl and E in cervical cancer has been poorly defined. In this study, we examined the expression of cyclins Dl and E by Northern blot technique and the status of human papil- lomavirus(HPV) type 16 and 18 by polymerase chain reaction in 25 cases of cervical carcinoma to explore the relationship between cyclins Dl and E and cervical cancer. We found cyclin Dl expression showed down-regulated expression in cervical cancer but cyclin E expression was increased in cancer group. Other clinicopathological prognostic factors were not correlated with cyclins D1 and E expression. Further study based on larger numbers of cases with correlation of cyclins D1 and E status and survival data will be needed to elucidate the use of cyclin expressions as prognostic factor.

Takaysu arteritis is a systemic disease characterized by stenosis or obstruction of aorta and its branches. Its etiology is unknown but clinical and serologic data suggest autoimmune process. Coronary artery involvement has been uncommon, but potentially fatal complication of Takayasu arteritis. A 41-year old female patients was presented with exertional dyspnea and anterioi chest pain of 2 week duration. Systolic bruit was heard at the both middle portion of internal carotid artery areas. Both radial arteries were palpated well but both femoral, popliteal and doralis pedis arteries were palpated weakly. Aortogram showed complete obstruction of descending thoracic aorta and collateral circulation of internal mammary artery. Coronary angiogram showed 80% stenosis at the middle portion of the right coronary artery. Calcium channel blocker and antiplatelet agent were prescribed. And her clinical symptom improved.

BACKGROUND: In this study, we assessed the 50% effective concentration (EC50) of sevoflurane for reducing a rocuronium-induced reaction, based on the Dixon's up-and-down method. We also assessed the 50 and 95% effective end-tidal concentration of sevoflurane (ETsev), based on the probit regression curve of the probability of nonwithdrawal reaction. METHODS: We conducted a prospective, double-blind study in 23 males and 24 females. After using 2.5% thiopental sodium (4 mg/kg), anesthesia was induced in the patients. The patients then inhaled sevoflurane with 5 vol% in 6 L/min of oxygen. When the target ETsev was achieved, a nurse injected the intubating dose of rocuronium (0.6 mg/kg) for 5-10 s under the free flow of intravenous fluid. After the nurse evaluated the response, the nurse recorded the maximum heart rate during 30 s and the mean arterial pressure after rocuronium injection. RESULTS: Based on Dixon's up-and-down method, the EC50 of sevoflurane was 2.5 alpha 0.5 vol% in males and 2.5 alpha 0.3 vol% in females. The probit regression curve of the probability of nonwithdrawal reaction showed that in males the 50% effective ETsev was 2.4 vol% (95% confidence interval [CI], 1.5-3.1 vol%) and the 95% effective ETsev was 3.5 vol% (95% CI, 2.9-11.0 vol%); in females, the 50% effective ETsev was 2.4 vol% (95% CI, 2.1-2.7 vol%) and the 95% effective ETsev was 3.0 vol% (95% CI, 2.7-4.5 vol%). CONCLUSIONS: The inhalation of sevoflurane during the induction period may provide a simple and reliable means of reducing rocuronium-induced reactions without adverse hemodynamic changes. There was no significant difference between males and females.

BACKGROUND: Elastic recoil contributes to the residual lumen reduction immediately after PTCA. We evaluated the factors to influence on immediate elastic recoil after the successful PTCA. METHODS: 88 patients(96 lesions) were studied by quantitative angiography. Angiograms were obtained in two identical near orthogonal projection before PTCA and immediately after the last balloon deflation. RESULTS: Immediately after PTCA, minimal luminal diameter increased from 0.7+/-0.6mm to 1.9+/-0.6mm and percent diameter stenosis was reduced from 77+/-20 to 34+/-21%. The calculated mean elastic recoil was 0.5+/-0.7mm in diameter and % elastic recoils were lesser both in calcified(3+/-23 vs 23+/-24%, p=0.04) and thrombotic(9+/-20 vs 23+/-35%, p=0.02) lesions. The elastic recoil increased significantly according to the inflation diameter of balloon(r=0.32, p<0.01. No significant correlation between the immediate elastic recoil and age, sex, risk factors, eccentricity and lesion length was shown. CONCLUSION: The elastic recoil immediately after a successful PTCA was dependent on the existance of calcium and thrombus on the target lesion and on the balloon size at the maximal inflation.

BACKGROUND: In korea, significant proportion of victims with out-of-hospital cardiac arrest have no change to survive because some physicians regard the victim with cardiac arrest outside the hospital as the dead and they do not attempt cardiopulmonary resuscitation(CPR). And we cannot expect bystander-initiated CPR and emergency medical system in resuscitating the victims with cardiac arrest. We studies the outcome of resuscitation attempts and the factor associated with survival in patients with out-of-hospital cardiac arrest in current situation of emegency medical system. Method: We attempted cardiopulmonary resuscitation(by standard guidelines) in 74 consecutive victims with non-traumatic out-of-hospital cardiac arrest in emergency department. RESULTS: Of 74 victims with cardiac arrest 35(47%) had no any restoration of spotaneous circulation(ROSC), 26(35%) had transient ROSC but died within 24 hours,6(8%) survived over 24 hours but died in the hospital, and 7(10%) discharged alive. Factors associated with survival were cardiac origin as a cause of cardiac arrest, ventricular fibrillation as a initial ECG rhythm, and short circulatory arrest time. CONCLUSION: Survival rate of victims with non-traumatic out-of-hospital cardiac arrest was 10%. Considering the feasibility to survive, CPR should be attempted in patients with out-of-hospital cardiac arrest if do-no-resusciate(DNR) is not indicated.

BACKGROUND: Several reports have suggested that preoperative nociceptive block with opioids and nonsteroidal antiinflammatory drugs (NSAIDs) may reduce postoperative pain. This study evaluated the effects of preemptive analgesia, the analgesic efficacy and safety of intravenous opioids and NSAIDs during the first 48 hours after lower abdominal surgery. METHODS: The 40 patients were randomized to either preemptive group or postincisional group. All subjects received IV bolus of 2 mg of morphine followed by continuous IV mixture (morphine 30 mg + ketorolac 90 mg + droperidol 2 mg in 90 ml of normal saline) via Baxter 2-Day Infusor(R). Evaluations included supplementary analgesics, analgesic pain assessment (visual analogue scale, VAS), time of first analgesic request, patient comfort (comfort scale), and side effects. RESULTS: There were no differences in number of patient requiring supplemental analgesic (3/20 vs 5/20), the time of first analgesic request (42.2 hours vs 37.5 hours), pain scores measured at each time, and patient comfort between two groups. There were minor complications such as nausea and somnolence in both groups, but no patients needed any treatment. CONCLUSIONS: Preemptive or postincisional morphine-ketorolac-droperidol infusion was equally effective for postoperative analgesia after lower abdominal surgery with minor complications. Further evaluation may be needed to determine whether preemptive analgesia has any advantages over postincisional analgesia.
