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.

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.

Effects of oral estrogen (Tibolone) on the urinary symptoms and urodynamics parameters were assessed by a double-blind prospective trial in 24 postmenopausal women. Patients were assessed subjectively and objectively before and after treatment by symptom score change, urethral pressure profiles and uroflow. There was statistical difference in the subjective response (symptom score) to treatment between the two groups (p<0.001), there was no significant urodynamic changes (p> 0.05). Although there was no significant urodynamic changes, estrogen treatment in postmenopausal women was effective to improve urinary symptoms. Careful observation with periodic follow up will be needed because of possible harmful side effects of estrogen.

4.Clinical Applications of Plasma B-type Natriuretic Peptide Assays in Preterm Infants with Patent Ductus Arteriosus.
Neonatal Medicine 2013;20(3):323-334
Hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants is a common and important problem associated with significant morbidity and mortality including: intraventricular hemorrhage, necrotizing enterocolitis and bronchopulmonary dysplasia. The rapid and accurate determination of the indications for therapeutic closure of hsPDA in preterm infants is important but often difficult. Currently used tools, such as the clinical findings, including heart failure and the typical echocardiographic features of hsPDA, have unsatisfactory sensitivity and/or specificity. Over the last decade, measurement of plasma B-type natriuretic peptide (BNP) levels using a commercially available bedside testing kit has been proposed to aid in the diagnosis and treatment of hsPDA in preterm infants. The present review analyzes the clinical usefulness of a rapid plasma BNP assay for the management of hsPDA in preterm infants and speculates on potential future therapeutic directions, including predicting subsequent hsPDA for early targeted treatment and predicting of treatment response for decision-making regarding surgical intervention before and after medical treatments.

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.

6.Retroperitoneal Liposarcoma (Pleomorphic Type): A Case Report.
Korean Journal of Urology 1996;37(10):1187-1190
A 66-year-old woman was admitted to our hospital because of a mass in the left abdomen. Ultrasonography, aortography and computed tomographic (CF) scanning revealed the mass occupying the entire left abdominal cavity and the left kidney displaced by huge and avascular mass. Also CT guided needle biopsy demonstrated liposarcoma. At operation, a huge yellow-brownish tumor found in the retroperitoneal space, was removed incompletely due to severe adhesion to the left external iliac artery The tumor was 12x11x10cm and weighed 560gm. Histologically, it was a pleomorphic type liposarcoma. She bas received adjuvant radiotherapy but recurred 10 months later.

Recently, a hydroxyapatite sphere has been increasingly used as a buried integrated orbital implant for the great improved motility of the prosthesis after enucleation. To allow more rapid ascess of vasculature into the hydroxyapatite implant, Dacron as a new synthetic wrapping material of the implant for anophthalmic sockets had been used and compared histologically with donor sclera in rabbits. At 4 weeks after implantation, fibrovascular ingrowth was found mainly near the scleral windows, where fibrosis extended 2 mm centrally in scleral-wrapped implants. In Contrast, in Dacron-wrapped implants, there was extensive fibrovascular infiltration through Dacron filaments and windows as well, making the hydroxyapatite sphere completely invested with fibrovascular tissue to the center within 4 weeks of implantation. Thus, Dacron as a new wrapping material appears to allow a more rapid vascularization into the hydroxyapatite implant than other collagen material without any serious complications, resulting in early rehabilitation with an artificial eye.

To evaluate the possibility of Dacron patch for artificial sclera. Dacron(polyethylene terephthalate) which is readily available, biocompatable, safe, and inert synthetic material was implanted in the area of full-thickness scleral defect in rabbits. The histopathologic examinations showed that fibrovascular tissue invested into all interstices of Dacron filaments and fibroconnective tissue encapsulation around Dacron patch had strong connection with collagen fibers of recipient sclera at 4 weeks after graft There were no adverse reactions such as retinal detachment and fibrous proliferation into the vitreous cavity except mild inflammatory response of surrounding tissue at the early postoperative stage. As a result, Dacron graft showed successful firm adhesion to the recipient sclera without serious complications. Thus, We think that Dacron could possibly be used, instead of donor sclera, as artificial scleral graft material for the surgical treatment of perforating scleral diseases.

9.Clinical Application of Inhaled Nitric Oxide Therapy in Persistent Pulmonary Hypertension of the Newborn.
Neonatal Medicine 2015;22(2):61-70
Inhaled nitric oxide (iNO) is recognized as a potent and selective pulmonary vasodilator that does not decrease systemic vascular tone. The therapeutic application of iNO in human was first described in 1991. Subsequent reports showed that iNO therapy was effective to improve oxygenation in infants with persistent pulmonary hypertension of the newborn (PPHN). Owing to its selective pulmonary vasodilator effects, iNO therapy is an important treatment for term newborns with hypoxemic respiratory failure due to PPHN. The Food and Drug Administration of the United States of America first approved iNO in 1999 for use as a medical gas to treat hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension in term and late preterm neonates. Thereafter, iNO therapy is clinically applied to treat PPHN in term and late preterm neonates without consensus. In this review, we focused on the clinical practice of iNO therapy in PPHN. Based on published studies, we discuss iNO initiation and withdrawal methods, respiratory support devices that complement iNO therapy, and the patient and gas monitoring during iNO therapy.

We present a case of a young female patient with fulminant hepatitis who showed an altered biodistribution of Ga-67, after being scanned twice at 10 month intevals. On initial scan, uptake of Ga-67 was increased in the liver, kidneys, and skeletons. Increased hepatic Ga-67 uptake may be explained by increased transferrin unbound Ga-67 that was taken up by the inflamed liver. The saturation of iron-binding proteins due to multiple transfusions may lead to increased renal and skeletal Ga-67 uptake. On follow-up scan hepatic Ga-67 uptake was markedly increased. Also increased Ga-67 uptake in the axial skeleton and normalized renal uptake were shown. The findings were consistent with iron deficiency anemia. This case demonstrates altered Ga-67 biodistribution associated with multiple transfusions, fulminant hepatitis, and iron deficiency anemia.
