Background: Although rhythm control could be the best for symptomatic atrial fibrillation (AF), some patients fail to achieve sinus rhythm (SR). This study aimed to identify clinical risk factors of failed electrical cardioversion (ECV). Methods: A total of 248 patients who received ECV for persistent AF or atrial flutter (AFL) were retrospectivelyreviewed. Patients were divided into three groups: Group 1 maintained SR for > 1 year, group 2 maintained SR ≤ 1 yearafter ECV, and group 3 failed ECV. SR maintenance was assessed using regular electrocardiography or Holter monitoring. Results: Patients were divided into group 1 (73, 29%), group 2 (146, 59%), and group 3 (29, 12%). The mean ageof patients was 60 ± 10 years, and 197 (79%) were male. Age, sex, and baseline characteristics were similar amonggroups. However, increased cardiac size, digoxin use, heart failure (HF), and decreased left ventricular ejection frac‑ tion (LVEF) were more common in group 3. Univariate analysis of clinical risk factors for failed ECV was increasedcardiac size [hazard ratio (HR) 2.14 (95% confidence interval [CI], 1.06–4.34, p = 0.030)], digoxin use [HR 2.66 (95% CI, 1.15–6.14), p = 0.027], HF [HR 2.60 (95% CI, 1.32–5.09), p = 0.005], LVEF < 40% [HR 3.45 (95% CI, 1.00–11.85), p = 0.038], and decreased LVEF [HR 2.49 (95% CI, 1.18–5.25), p = 0.012]. Among them, HF showed clinical significance only by multivariate analysis [HR 3.01 (95% CI, 1.13–7.99), p = 0.027]. Conclusions Increased cardiac size, digoxin use, HF, LVEF < 40%, and decreased LVEF were related to failed ECV for persistent AF or AFL. Among these, HF was the most important risk factor. Further multi-center studies including greater number of participants are planned.

It is important to identify therapeutic compounds with no adverse effects for use in the chemotherapy of patients with bone-related diseases. The aim of this study was to identify a new compound that inhibits osteoclast differentiation and bone resorption. Herein, we examined the effects of 1',2'-dihydrorotenone on osteoclast differentiation and bone resorption in vitro and in vivo. 1',2'-dihydrorotenone inhibited receptor activator of NF-kappaB ligand (RANKL)-induced osteoclast differentiation of cultured bone marrow macrophages (BMMs) in a dose-dependent manner. However, 1',2'-dihydrorotenone did not exert cytotoxic effect on BMMs. 1',2'-dihydrorotenone suppressed the expression of c-fos and NFATc1 as well as osteoclast-specific genes in BMMs treated with RANKL. Treatment with RANKL inhibited the expression of inhibitors of differentiation/DNA binding (Id)1, 2, and 3; however, in the presence of 1',2'-dihydrorotenone, RANKL did not suppress the expression of Id1, 2, and 3. Furthermore, 1',2'-dihydrorotenone inhibited bone resorption and considerably attenuated the erosion of trabecular bone induced by lipopolysaccharide treatment. Taken together, these results suggest that 1',2'-dihydrorotenone has the potential to be applied in therapies for bone-related diseases.

PURPOSE: We performed this study to assess the incidence of venous complications, including portal vein and hepatic vein stenosis, in both split cadaveric and living donor liver transplants and to assess the diagnostic and therapeutic modalities of these lesions. METHODS: Seventy-six liver transplantations were performed in 75 children with split (5) or living donor (71) graft between December 1994 and March 2002. Patients' data were analyzed retrospectively with special emphasis on venous complications. RESULTS: Venous complications occurred in 14 patients (18.6%) including hepatic vein stenosis in 8, portal vein stenosis in 4, portal vein thrombosis in 1, and combined portal vein thrombosis and hepatic artery stenosis in 1 patient. Venous complications were accompanied by abnormality of liver fuction, ascites, progressed splenomegaly, and gastrointestinal bleeding. To diagnose the venous complications, Doppler ultrasonography was performd at first, and those were confirmed by angiography or CT. Hepatic vein stenosis was managed by percutaneous transhepatic angioplasty (6), angioplasty followed by reposition of graft (1), and supportive care only 1 patient. Portal vein complications were managed by angioplasty (4), angioplasty followed by mesocaval shunt (1), and combined revascularization and angioplasty (1). The overall survival rate was 86% (12 of 14 patients). CONCLUSION: Close surveillance of the complication of vascular anastomoses and multidisciplinary approach to treat of venous complication after pediatric liver transplantation have made it possible to reduce the graft loss and mortality. Aggressive and successful radiologic intervention should be considered to eliminate the need for surgical revision, portacaval shunting or retransplantation.

Fenoverine is a non-atropine like spasmolytic drug that inhibits calcium channel currents in the smooth muscle. It has been occassionally reported that fenoverine can cause rhabdomyolysis under the certain conditions such as hepatic dysfunction, concomitant use of HMG-CoA reductase, mitochondrial myopathy, lipid storage myopathy or malignant hyperthermia. However, there is no report of fenoverine-induced rhabdomyolysis in type 2 diabetic nephropathy patient. So we describe here a case of fenoverine-induced rhabdomyolysis in type 2 diabetic patient. A 70-year-old man had both lower legs and shoulder pain for 5 days prior to hospital admission. He was a type 2 diabetic patient and had been managed for diabetic nephropathy. He had been consumed common doses of fenoverine for 20 days due to abdominal pain and diarrhea. Results of investigations showed evidence of rhabdomyolysis. Fenoverine therapy was stopped after admission and he was treated supportive care, his condition was recovered. In this case, renal function impairment may have been a predisposing factor for fenoverine-induced rhabdomyolysis. The incidence of muscular complications of fenoverine therapy could be reduced by avoidance of prescription of the drug in patients with diabetic nephropathy.

OBJECTIVES: To evaluate the clinical manifestations and perinatal outcomes of pregnancies complicated with gestational impaired glucose tolerance (GIGT) and gestational diabetes mellitus (GDM). METHODS: We performed 50gm oral glucose tolerance test (OGTT) for GIGT and GDM screening in 4,367 pregnant women at 24-28 weeks of gestation. In 1,010 women with plasma glucose level over 130mg/dl, 753 women underwent 100gm OGTTs at 28-32 weeks of gestation. According to the NDDG criteria, 113 cases with GIGT (single positive level of OGTT ; group 2), 125 cases with GDM (group 3), and 515 cases with control (group 1) were identified among the 753 cases. Retrospective review of outcome of these patients was performed. ANOVA and chi-square test were used to determine the statistical significance. RESULTS: The incidence of GIGT and GDM was 2.7%, 3.0%. The prepregnant body mass index (21.4+/- 3.0kg/m2, 21.3+/-2.8kg/m2, 23.2+/-4.1kg/m2), overweight of BMI over 26 (7.4%, 4.4%, 14.4%) and obesity of BMI over 30 (1.2%, 0.0%, 8.0%) was significantly higher in group 3 than group 1 (p<0.05). We defined poor maternal outcome as those suffering from any one of birth canal injury, hydramnios or oligohydramnios, preeclampsia, cesarean delivery due to cephalopelvic disproportion, dystocia, fetal distress. Group 3 showed most highest poor maternal outcome (22.3%, 28.3%, 39.2%, p<0.05). And we defined poor neonatal outcome as those suffering from any one of hyperbilirubinemia, hypoglycemia, congenital anomaly, admission to neonatal intensive care unit due to respiratory distress syndrome. Group 2 and group 3 showed poor neonatal outcome than group 1 (6.2%, 13.3%, 21.6%, p<0.05). CONCLUSION: Pregnancies complicated with GDM showed poor maternal and neonatal outcome, and GIGT experienced no adverse maternal outcomes but showed poor neonatal outcomes compared to normal pregnancy, and showed less correlation with obesity than GDM. Further study of pathophysiology and proper management of GIGT will be mandatory.

Polycystic ovary syndrome is characterized by symptoms of oligomenorrhea, amenorrhea, infertility, hirsutism and obesity. It is known that the women with such diseases would have higher risks to coronary heart diseases, hypertension, DM and endometrial cancer later on, Known risk factors of endometrial cancer are nullipara, late menopause, obesity, DM, unopposed estrogen, tamoxifen treatment, and atypical endometrial hyperplasia ect. 75% of endometrial cancer occurs in age over 50 and 4% of endometrial cancer occurs in age under 40. Particulary endometrial cancer concurrent polycystic ovary syndrome occurs usually in people under age 40 and is commonly well differentiated cell type and is related to good prognosis. We experienced a case of endometrial cancer with polycystic ovary syndrome, who was early dignosed, presented with infertility and got an operation in our hospital, and report this case with a brief review of literature.

The uterus with rudimentary horn occurs as a result of a lack of development during fetal life of the middle and lower parts of one of the Miillerian ducts, in which there is a failure of fusion of the two ducts, The incidence of this uterine anomaly is rare. Many cases of rudimentary uterine horn are not discovered since they do not become involved in a pregnancy, and thus remain symptomless and uncomplicated, and the diagnosis usually being made only with pregnancy with rupture. In this presentation, we describe a case of diagnosis and management of unruptured non-communicating rudimentary uterine horn pregnancy at the third trimester. The patient diagnosed by ultrasonography and MRI, was hospitalized for further evaluation and delivery under the impression of unruptured non-communicating rudimentary horn pregnancy. A living male infant weighing 1,930 gm was delivered by cesarean section at 33+l weeks due to impending preterm labor. Some articles concerned this subject were reviewed briefly to discuss relevant method of diagnosis, treatment, and clinical characteristics.

BACKGROUND: Nonimmune hydrops fetalis has become an important perinatal problem since it was first described in 1943. Although recent advances in antenatal ultrasound have made it possible to detect and manage nonimmune hydrops fetalis in early pregnancy, the perinatal mortality is still high. OBJECTIVE: To obtain clinically useful data regarding antenatal diagnosis, management, and perinatal outcomes of nonimmune hydrops fetalis, and to assist clinicians offer proper antepartum counseling and obstetric management which may be able to improve prognosis. Study design: We retrospectively reviewed 33 cases of nonimmune hydrops fetalis delivered in our hospital over a 4-year period. RESULTS: The antenatal diagnosis was possible by ultrasonography in all cases. Accumulation of fluid in fetal serous cavity and generalized skin edema were observed in all cases. A probable etiology was found in 23 (69.7%) cases through ultrasonography, various laboratory studies including fetal karyotyping, and autopsies. These were cardiovascular (4), respiratory (6), chromosomal (4), skeletal (1), and others (8). Despite extensive diagnostic studies, no definite etiology was found in 10 (30.3%) cases. Excluding the ten fetuses delivered after induced abortion, eight infants were born alive and six died in the neonatal period. The mortality rate was 91.3% (21/23). CONCLUSION: Nonimmune hydrops fetalis represents a very poor perinatal outcome. It is suggested that to improve the prognosis, various antenatal and postnatal approaches to find associated etiologic factors should be performed, and intensive perinatal cares are needed.
