Uterine tumors resembling ovarian sex-cord tumors (UTROSCT) are very rare tumors that occur mainly in the uterine fundus of women in reproductive age. These tumors can be classified into group 1 and group 2 by histological results. In group 1, epithelial-like differentiation is partially observed in the tumors. In group 2, sex-cord elements are predominant in uterine mural mass. We experienced UTROSCT group 1 in a 29-year-old woman who complained of severe abdominal pain that started one week after delivery and UTROSCT group 2 case in a 49-year-old woman who complained of dysfunctional uterine bleeding. We report two different types of UTROSCT cases that we experienced.

Isolated fetal ascites may be different from general category of nonimmune hydrops in both prenatal course and prognosis. We experienced one case of isolated fetal ascites of unknown origin treated by in utero ultrasound-directed paracentesis and so present it with brief review of literature.

Ovarian vein thrombosis (OVT) is a rare disease with complications that can be life-threatening. An ovarian vein thrombus in a gestational trophoblastic neoplasia (GTN) is an extremely rare condition that has not been previously reported in the literature. We report the case of a 23-year-old woman who presented with symptoms of amenorrhea for 15 weeks and 6 days along with intermittent lower abdominal pain. She was diagnosed with a hydatidiform mole, and a metastatic workup was scheduled. Abdominal computed tomography showed a right ovarian vein thrombus. She received methotrexate chemotherapy combined with oral anticoagulants. Complete radiological remission was obtained. During the 12-month follow-up period, no disease progression or recurrence was noted. Early recognition and detection of the condition are of the utmost importance. The differential diagnosis of OVT must be considered when there is unexplained abdominal pain, fever, and leukocytosis during the diagnosis and treatment of GTN. A high level of suspicion is required for prompt diagnosis of OVT.

Isolated tubal torsion is a rare disease that causes acute lower abdominal pain. In most of cases, the ovary and the fallopian tube are together twisted due to an ovarian tumor, but the fallopian tube alone is rarely twisted. Tubal torsion mainly occurs in fertile women, and it rarely occurs prior to menarche and during menopause. We experienced a case where isolated tubal torsion occurred in a perimenopausal female with total abdominal hysterectomy, while the findings showed a normal ovary. We report this case with a brief review of related literature.

PURPOSE: Previous reports demonstrated that nitric oxide (NO) plays immuno-regulatory role in immune responses including allograft rejection response. However, its possible role in xenograft rejection has not been examined. The purpose of this study is to elucidate possible immunoregulatory role of NO in skin xenograft rejection by determining the expressions of chemokines and cytokines in the presence or absence of iNOS inhibitors. METHODS: C57BL/6J mice were grafted with Lewis rat tail skin. The mice were injected intraperitoneally with potent inhibitor of iNOS, aminoguanidine (AMG, 200 mg/kg). Graft survival was monitored and cytokine and chemokine mRNA expressions were measured by real-time RT-PCR in context with iNOS expression on day 3, 5, 7 and 9. These data were compared with those of control mice (saline injected). RESULTS: Compared with the control mice, the AMG treated mice showed delayed xenograft rejection by approximately 3 days (8.9+/-0.7 days vs 11.7+/-1.2 days). Infiltrations of CD11b+, MOMA-2+ cells and neutrophils were significantly reduced but not CD4+ and CD8+ cells in AMG treated graft. The expression of cytokines such as IL-1beta, IL-2, IL-6, IL-12, IFN-gamma in AMG treated graft significantly decreased (P<0.01) whereas IL- 10, TNF-alpha and TGF-beta1 were not changed or enhanced. Additionally, the expression of CC-chemokines such as RANTES and MIP-1alpha significantly reduced (P<0.01) whereas CXC-chemokines such as IP-10 and MIG did not change. CONCLUSION: These data imply that NO suppression by iNOS inhibitor may prolong rat to mouse skin xenograft survival through a selective inhibition of pro-inflammatory cytokines and chemokines. The possible role of NO in transplant rejection can be, therefore, extended to regulation of cytokine and chemokine expressions.

An ultrasonographic examination revealed increased fetal bladder size and decreased AFI as well as fetal bilateral hydronephrosis at 173weeks' gestation. Diagnosis of the fetal posterior urethral valve syndrome was made. Percutaneous fetal bladder puncture with aspiration and amniocentesis was performed. The fetus was normal male karyotype and with a predicted good renal function(sodium concentration, chloride concentration, and osmolarity at 74 mEq/L, 60 mEq/L, and 148 mOsm, respectively). So, the fetus underwent amnioinfusion and vesico-amniotic shunting procedure (VASP) using a double-basket catheter at 194weeks' gestation in order to prevent development of dysplastic kidneys and hypoplastic lungs. The healthy male baby was delivered at 384weeks' gestation and had normally functioning kidney. Cutaneous vesicostomy was performed for the newborn since the urethral orifice was small. The one year old infant is now well and waiting for urethroscopic valve ablation procedure.

A supernumerary ovary is a rare gynecological anomaly, and is usually excised due to its malignant transformation potential. We report a case of a supernumerary ovary and endometriosis situated on the anterior rectosigmoid colon. When laparoscopy was conducted, a firm, 5-cm mass was discovered on the anterior rectosigmoid colon along with normal ovaries. In this case, the discovery of a supernumerary ovary implied the presence of endometriosis. It is unusual for endometriosis and a supernumerary ovary to exist simultaneously.

Background/Aims:
Fexuprazan, a novel potassium-competitive acid blocker, was developed for treating acid-related disorders. Pharmacokinetic and pharmacodynamic properties of fexuprazan, unlike those of proton pump inhibitors, are independent of food effect. This study aims to evaluate differences in efficacy and safety of fexuprazan in patients with erosive esophagitis (EE) according to the timing of dosing.
Methods:
In this multicenter, open-label noninferiority study, patients who had typical reflux symptoms with endoscopically confirmed EE were randomized 1:1 to receive fexuprazan 40 mg daily 30 minutes before or after meal. Treatment was completed after 2 weeks or 4 weeks when healing was endoscopically confirmed. The primary endpoint was the proportion of patients with healed EE confirmed by endoscopy up to week 4. Safety endpoints included treatment-emergent adverse events (TEAEs).
Results:
In the prior-to-meal group (n = 89) and after-meal group (n = 86), 4-week EE healing rates were 98.77% and 100.00% (difference, 0.01%; 95% CI, –0.01% to 0.04%) and 2-week EE healing rates were 95.77% and 97.14% (difference, 0.01%; 95% CI, –0.05% to 0.07%), respectively. TEAEs were 9.78% and 8.70% in the prior-to-meal group and the after-meal group, respectively.
Conclusions
Non-inferiority analysis revealed that taking fexuprazan after meal was non-inferior to taking fexuprazan before meals in patients with EE. The frequency of adverse events was similar between the 2 study groups. The drug is safe and effective for healing EE regardless of the timing of dosing.
