Carcinoma of the fallopian tube accounts for less than 1% of all cancers of the female genital tract. The histology and behavior of fallopian tube cancer are simillar to ovarian cancer; thus evaluation and treatment are also essentially the same. Unlike ovarian cancer, fallopian tube cancer begins in a hollow viscus, and early lesions may be less likely to be associated with extensive intraperitoneal carcinoma. Two postmenopausal women presented with a pelvic mass. Pathologic examination of the resected specimens revealed primary adenocarcinoma of the fallopian tube. We have experienced two cases of fallopian tube cancer and reported with brief review of literature

Purpose:
A case of a huge ethmoid sinus and orbital cyst causing ocular deviation initially diagnosed as a mucocele-like cyst and after orbitotomy eventually discovered to be a naso-orbital encephalocele is described.Case summary: A 5-year-old male with no previous medical history presented with a palpable mass in the medial canthus area with left exodeviation of the left eye. His best-corrected visual acuity was 20/25 in the right eye and 6/12 in the left eye with limitation of motion of -4 at adduction in the left eye. Brain magnetic resonance imaging scans revealed a 3.0 × 2.5 × 2.5 cm-sized cystic mass suspected as a mucocele or nasolacrimal duct cyst invading the orbital space. The cyst was removed using a Lynch and caruncle incision, and intracystic fluid was aspirated. During the excision, a small defect of the skull base was detected with cerebrospinal fluid (CSF) leakage and leaking point of dura was sealed. His pathologic result was disorganized glial and fibrous tissue, consistent with encephalocele. Three days later, CSF leakage recurred. On postoperative day 8, duroplasty was performed. A one month later, his best-corrected visual acuity was 6/12 in the left eye with orthotropic eye position. Limitation of motion was improved to -1 at adduction with enophthalmos. No other complications were detected.
Conclusions
Congenital naso-orbital encephalocele invading the orbit is rare. However, a cystic mass in the sinuses involving the orbit should be considered, rendering thorough physical and radiologic examinations including computed tomography scans necessary to look for bone defects.

OBJECTIVES: For estimating the antenatal fetal wellbeing to develop new analysis method of fetal heart rate(FHR) with electronic Fetal Heart Rate Monitoring(eFHRM) and computer. METHODS: Heart rate signal is received from distressed fetus using eFHRM. It is necessary to carry out low pass filtering as a preprocess for the nonlinear method. Nonlinear parameters are calculated and classified to investigate the relations between these parameters and values of umbilical cord blood gas. RESULTS: By dividing values of the umbilical cord blood gas into 5 fetuses of acidemic group and 17 fetuses of non-acidemic group after 22 neonates who presented fetal distress were born, the following results as compared with nonlinear chaotic analysis result were obtained. 1. Delay time through AMI for acidemic group was 16.80+/-3.11, and was higher than 15.41+/-2.27 for non-acidemic group, and is not significant in statistics. 2. Embedding Dimension calculated with FNN method was 5.60+/-2.07 for acidemic group, and 4.71+/-1.26 for non-acidemic group, and it was not significant statistically. 3. Correlation dimension for acidemic group was 1.41+/-0.20, and was higher than 1.10+/-0.38 for non-acidemic group, and is not significant in statistics. 4. Mean crossing value by isoangular return map was 28.80+/-11.34 for acidemic group, and 16.65+/-7.00 for non-acidemic group, and it was significant statistically(P=0.008). 5. In comparison of information entropy in 1-D ED, acidemic group was 6.32+/-0.38 and non-acidemic group was 6.20+/-0.28 and it was not significant statistically. Also, in comparison of value in 2-D ED, acidemic group was 10.20+/-0.34. It was higher than non-acidemic group of 9.51+/-0.43 significantly in statistics(P=0.004). But, in comparison of value in 2-D EP, acidemic group was 8.78+/-0.86 and non-acidemic group is of 9.22+/-0.74 and it wasn't significant statistically. And, 2-D ED(DI) value was 10.64+/-0.14 for acidemic group and 10.51+/-0.18 for non-acidemic group, and it wasn't significant statistically. CONCLUSIONS: By the above result, nonliner dynamics and chaotic analysis of heart rate data with computer can serve as a new diagnosis method which may estimate the fetal wellbeing with real time. Through further studies for establishment of diagnosis standard and computer programming, real time diagnosis method shall be applied to clinical practice.

Idiopathic CD4+ T-lymphocytopenia is a rare immune disorder characterized by an unexplained deficit of CD4+ T cells and results in various opportunistic infections. Herein, we report a case of new onset weakness in a 10-year-old boy secondary to motor axonal neuropathy associated with idiopathic CD4+ T-lymphocytopenia. The patient was referred to rehabilitation for an evaluation of progressive weakness involving all four limbs. A subsequent nerve conduction study and needle electromyography identified motor axonal neuropathy. At that time, laboratory studies specific to the differential diagnosis of motor axonal neuropathy were performed; however, the abnormality noted was a decreased CD4+ T-lymphocyte count. Motor axonal neuropathy represents an uncommon manifestation of idiopathic CD4+ T-lymphocytopenia and is probably associated with an underlying immune process.

Uterine torsion is defined as the mtation of more than 45 degrees around the long axis of the uterus or a rotation which is severe enough to produce symptoms. Torsion of the human pregnant uterus is a very rare complication. The diagnosis is problematic and is often made during a cesrean section due to inhibited labor. Torsion of the human pregnant uterus can be caused by myoma or other uterine abnormalities, ovarian cysts, adhesions, abnormal fetal presentations, or fetal abnormalities ( though no cause can be found in about 20% of cases ). Uterine torsion produces symptoms of varying severity depending on the degree of rotation, and duration of the pregnancy. High mortality rates for both mother and infant have been reported. We experienced one case of the torsion of term pregnant uterus and report this case with a brief review of the concerned literature.

OBJECTIVES: Vaginal birth or trial of labor after previous cesarean section has become one of the most remarkable changes in obstetric practice. The safety and efficacy of a trial of labor and vaginal birth after previous cesarean are well documented. The purpose of this report is to predict the likelihood of vaginal birth in patients undergoing a trial of labor after previous cesarean delivery using factors known at the time of hospital admission. METHOD: In this retrospective study, 120 women who attempted vaginal birth at Kyung-Hee University Hospital from March 1997 to March 1999. An attempt to identify possible prognostic factors for success of such a trial was made and we evaluated the variables of significant predictive value and the patients' characteristics in the success group and failure group of women who attempted VBAC. RESULT: 87 cases(72.5%) in 120 cases succeeded in VBAC and 33 cases(27.5%) failed. In this comparative groups in VBAC, there was significant difference in CPD index(cephalopelvic disproportion index) and Bishop score, but no significant difference in gestational age, the estimated fetal weight by sonography and newborn birth weight. CONCLUSION: In this study, Bishop score and CPD index and age may be useful and valid predictor of success in VBAC and this information could be particularly valuable. The CPD index may prove most important in determining if a vaginal birth should occur after a cesarean section because it can clearly identify some patients who need a repeat cesarean section.

A spontaneous rupture of the kidney due to a metastatic choriocarcinoma, which is associated with a normal pregnancy, is very rare. A 33-year-old female patient presented with sudden colicky right flank pain on the 5th day after a Cesarian Section. An abdominal CT scan showed evidence of a right renal rupture with a perirenal hematoma. Under the impression of a spontaneous rupture of right kidney, an exploratory laparotomy with a radical nephrectomy was performed. The pathologic findings revealed a renal parenchymal rupture due to a metastatic choriocarcinoma.

Percutaneous mitral balloon valvuloplasty (PMBV) is the treatment of choice for mitral stenosis. Only a few reported cases have been reported in PMBV patients worldwide. In this study, a case of a 34 year-old female with infective endocarditis a year after PMBV is presented. The patient presented with fever, and peripheral vascular symptoms. Transthoracic echocardiography showed vegetation on the anterior mitral leaflets and Staphylococcus Viridans was isolated from blood cultures. The patient was successfully treated with Amoxicillin + Clavulate and Gentamicin. Further studies on the correlation between PMBV and infective endocarditis are needed.

The epithelial-mesenchymal transition (EMT) is important for embryonic development and the formation of various tissues or organs. However, EMT dysfunction in normal cells leads to diseases, such as cancer or fibrosis. During the EMT, epithelial cells are converted into more invasive and active mesenchymal cells. E-box-binding proteins, including Snail, ZEB and helix-loop-helix family members, serve as EMT-activating transcription factors. These transcription factors repress the expression of epithelial markers, for example, E-cadherin, rearrange the cytoskeleton and promote the expression of mesenchymal markers, such as vimentin, fibronectin and other EMT-activating transcription factors. Signaling pathways that induce EMT, including transforming growth factor-beta, Wnt/glycogen synthase kinase-3beta, Notch and receptor tyrosine kinase signaling pathways, interact with each other for the regulation of this process. Although the mechanism(s) underlying EMT in cancer or embryonic development have been identified, the mechanism(s) in embryonic stem cells (ESCs) remain unclear. In this review, we describe the underlying mechanisms of important EMT factors, indicating a precise role for EMT in ESCs, and characterize the relationship between EMT and ESCs.
