Foreign bodies in the stomach are usually ingested by children under the age of 5 years, persons with dentures and alcoholics or mentally disturbed individuals. Many patients will be asymptomatic and will be brought in by parents with a history of having swallowed something. The ingested foreign bodies are mainly coins, particles of metal, fish bones and etc. A toothpick in the stomach has been rarely reported in an alert adult. Here, we present a case of a patient with toothpick stuck in the stomach, that she did not realize she had swallowed. It was removed by an endoscopy without any complications. A 57 year-old woman was admitted to Uijoagbu St. Mary's hospital because of epigastric pain for 10 days. The pain persisted constantly in the epigastrium and aggravated after meals. Sbe had an episode of vomiting during these days. A yellowish white, thin, stiff material 1.5 cm long was found by an endoscopic examination stuck at the less curvature of the antrum. It was removed by the endoscopic biopsy forceps and was proved to be an wooden toothpick, sharp at both ends, with a length of 6.6cm and a diameter of 0.2 cm. There was a small ulcer at the site of the removed toothpick and mild bleeding from the ulcer. The epigastric pain was relieved after the removal of the toothpick. She did not realize she had swallowed the toothpick. Four days later, a follow-up endoscopic examination revealed closed ulcer and no bleeding. She was discharged without complications.

Chyle is the digestive product absorbed from intestinal lymphatics which the component have high concentration of triglyceride and protein. The various pathological circumstances which give rise to intrathoracic effusion of chyle are well documented and so the etiology is clearly defined in most instances. However, the occurrence of chylothorax in early infancy, in the absence of other demonstrable diseases and without apparent birth trauma, suggests the existence of congenital malformation of the thoracic ducts. We lately experienced a 20 day old new born who was proved to have congenital chylothorax by clinical history and laboratory findings. So we report the clinical findings and laboratory findings with the review of the literatures on congenital chylothorax.

OBJECTIVE: To assess the feasibility and clinical efficacy of laparoscopic myomectomy (LM). METHODS: We analyzed retrospectively the data for 110 LM preformed at Kangbuk Samsung Hospital between July 2003 and July 2006. We reviewed their clinical charts and the operative and anesthetic records, and analyzed data on the patients' age, parity, previous operative history, preoperative indication, the diameter of the largest myoma, operating time, number of the removed myoma, hospital stay, change of the hemoglobin concentration from preoperative to postoperative day 1, concomitant procedures, histopathological reports, and complications. RESULTS: The mean age of the patients was 35.7+/-5.8 years, the mean parity was 0.8+/-0.9, and 26 (23%) patients had a previous operative history. The most common operative indication was a palpable abdominal mass (46 patients, 41.9%), followed by chronic pelvic pain (32 patients, 29.0%), abnormal uterine bleeding (24 patients, 21.8%), urinary frequency (7 patients, 6.4%), and infertility (1 patient, 0.9%). The mean operating time was 82.9+/-30.8 minutes, and the mean diameter of the largest myoma was 7.1+/-2.3 cm. The heaviest of the removed myoma weighed 795 gm. The mean change of the hemoglobin concentration was 2.2+/-1.1 g/dL, and the mean hospital stay was 3.5+/-1.4 days. Postoperatively, transfusions were done 10% (11 cases) of patients, and 2 cases of paralytic ileus and a case of subcutaneous emphysema were noted. Conversion rate to laparotomy was 0.9% (1 case). CONCLUSION: LM for various sized myomas can be performed successfully and effectively by decreasing laparoconversion, if the surgical team and the laparoscopic surgeon are experienced and enhanced equipment is available.

PURPOSE: To investigate the effect of oncostatin M (OSM) on protein expression levels and enzymatic activities of matrix metalloprotainase (MMP)-2 and MMP-9 in primary trophoblasts and the invasiveness thereof under normoxia and hypoxia conditions. MATERIALS AND METHODS: Protein expression levels and enzymatic activities of MMP-2 and MMP-9 in primary trophoblasts under normoxia and hypoxia conditions were examined by Western blot and zymography, respectively. Effects of exogenous OSM on the in vitro invasion activity of trophoblasts according to oxygen concentration were also determined. Signal transducer and activator of transcription 3 (STAT3) siRNA was used to determine whether STAT3 activation in primary trophoblasts was involved in the effect of OSM. RESULTS: OSM enhanced protein expression levels and enzymatic activities of MMP-2 and MMP-9 in term trophoblasts under hypoxia condition, compared to normoxia control (p < 0.05). OSM-induced MMP-2 and MMP-9 enzymatic activities were significantly suppressed by STAT3 siRNA silencing under normoxia and hypoxia conditions (p < 0.05). Hypoxia alone or OSM alone did not significantly increase the invasiveness of term trophoblasts. However, the invasion activity of term trophoblasts was significantly increased by OSM under hypoxia, compared to that without OSM treatment under normoxia. CONCLUSION: OSM might be involved in the invasiveness of extravillous trophoblasts under hypoxia conditions via increasing MMP-2 and MMP-9 enzymatic activities through STAT3 signaling. Increased MMP-9 activity by OSM seems to be more important in primary trophoblasts.

OBJECTIVE: To evaluate the significance of fetal Doppler parameters in predicting adverse neonatal outcomes and the risk of cesarean delivery due to non-reassuring fetal status, in severe small for gestational age (SGA) fetuses of late preterm and term gestation. METHODS: Fetal brain and umbilical artery (UmA) Doppler parameters of cerebroplacental ratio (CPR) and UmA pulsatility index (PI) were evaluated in a cohort of 184 SGA fetuses between 34 and 41 weeks gestational age, who were less than the 5th percentile. The risks of neonatal morbidities and cesarean delivery due to non-reassuring fetal status were analyzed. RESULTS: Univariate analysis revealed that abnormal CPR was significantly associated with cesarean delivery due to non-reassuring fetal status (P=0.018), but not with neonatal morbidities. However, abnormal CPR did not increase the risk of cesarean delivery due to non-reassuring fetal status in multivariate logistic regression analysis. Abnormal CPR with abnormal PI of UmA was associated with low Apgar score at 1 minute (P=0.048), mechanical ventilation (P=0.013) and cesarean delivery due to non-reassuring fetal status (P < 0.001), in univariate analysis. It increased risk of cesarean delivery for non-reassuring fetal status (adjusted odds ratio, 7.0; 95% confidence interval, 1.2–41.3; P=0.033), but did not increase risk of low Apgar score or mechanical ventilation in multivariate logistic regression analysis. CONCLUSION: Abnormal CPR with abnormal PI of UmA increases the risk of cesarean delivery for non-reassuring fetal status, in severe SGA fetuses of late preterm and term. Monitoring of CPR and PI of UmA can help guide management including maternal hospitalization and fetal monitoring.

BACKGROUND: The purpose of this study was to compare the fetal/infant mortality risk associated with each additional week of expectant management to that associated with immediate delivery in women with multiple gestations. METHODS: This was a retrospective national cohort study of 94,170 multiple deliveries, 92,619 (98.4%) twin and 1,352 (1.44%) triplet pregnancies, between 32 0/7 and 42 6/7 weeks of gestation recorded in the Korean vital statistics database. We investigated the risks of stillbirth and infant death after birth in Korea according to the week of gestation in twin and triplet pregnancies. RESULTS: The risk of stillbirth significantly increased between 34 and 35 weeks of gestation and between 37 and 38 weeks of gestation in twin pregnancies and between 34 and 37 weeks of gestation in triplet pregnancies. The risk of infant death following delivery gradually decreased as pregnancies approached full term. Week-by-week differences were statistically significant between 33 and 34 weeks, with decreasing risks of infant death at advancing gestational ages in twin pregnancies. At 37 weeks of gestation, the relative risk of mortality was significantly higher with expectant management compared with immediate delivery (relative risk, 3.00; 95% confidence interval, 1.41–6.38). CONCLUSION: In twin pregnancies, delivery at 37 weeks of gestation can minimize the risks of stillbirth and infant death in uncomplicated cases, although individual maternal and fetal characteristics must be considered when determining the optimal timing of delivery. In multiple pregnancies, close fetal surveillance is needed after 34 weeks of gestation.

PURPOSE: Bacteremia is a major infectious complication associated with mortality in liver transplant recipients. The causative organisms and clinical courses differ between medical centers due to variations in regional bacterial epidemiology and posttransplant care. Further, living donors in Korea contribute to 83% of liver transplants, and individualized data are required to improve survival rates. PATIENTS AND METHODS: We retrospectively analyzed 104 subjects who had undergone living-donor liver transplant from 2005 to 2007. RESULTS: Among the 144 consecutive living-donor liver transplant recipients, 24% (34/144) developed bacteremia, 32% (46/144) developed non-bacteremic infections, and 44% (64/144) did not develop any infectious complications. Forty episodes of bacteremia occurred in 34 recipients. The major sources of bacteremia were intravascular catheter (30%; 12/40), biliary tract (30%; 12/40), and abdomen (22.5%; 9/40). Gram-positive cocci were more common (57.5%; 23/40) than Gram-negative rods (32.5 %; 13/40) and fungi (10%; 4/40). The data revealed that the following factors were significantly different between the bacteremia, non-bacteremic infection, and no infection groups: age (p = 0.024), posttransplant hemodialysis (p = 0.002), ICU stay (p = 0.012), posttransplant hospitalization (p < 0.0001), and duration of catheterization (p < 0.0001). The risk factors for bacteremia were older than 55 years (odds ratio, 6.1; p = 0.003), catheterization for more than 22 days (odds ratio, 4.0; p = 0.009), UNOS class IIA (odds ratio, 6.6; p = 0.039), and posttransplant hemodialysis (odds ratio, 23.1; p = 0.001). One-year survival rates in the bacteremic, non-bacteremic infection, and no infection groups were 73.2%, 91.3%, and 93.5%, respectively. CONCLUSION: Early catheter removal and preservation of renal function should focus for improving survival after transplant.
