PURPOSE: It is to examine clinical manifestations, early biochemical indicators, and risk factors for non-oliguric hyperkalemia (NOHK) in extremely low birth weight infants (ELBWI). MATERIALS AND METHODS: We collected clinical and biochemical data from 75 ELBWI admitted to Ajou University Hospital between Jan. 2008 and Jun. 2011 by reviewing medical records retrospectively. NOHK was defined as serum potassium > or =7 mmol/L during the first 72 hours of life with urine output > or =1 mL/kg/h. RESULTS: NOHK developed in 26.7% (20/75) of ELBWI. Among NOHK developed in ELBWI, 85% (17/20) developed within postnatal (PN) 48 hours, 5% (1/20) experienced cardiac arrhythmia and 20% (4/20) of NOHK infants expired within PN 72 hours. There were statistically significant differences in gestational age, use of antenatal steroid, and serum phosphorous level at PN 24 hours, and serum sodium, calcium, and urea levels at PN 72 hours between NOHK and non-NOHK groups (p-value <0.050). However, there were no statistical differences in the rate of intraventricular hemorrhage, arrhythmia, mortality occurred, methods of fluid therapy, supplementation of amino acid and calcium, frequencies of umbilical artery catheterization and urine output between the two groups. CONCLUSION: NOHK is not a rare complication in ELBWI. It occurs more frequently in ELBWI with younger gestational age and who didn't use antenatal steroid. Furthermore, electrolyte imbalance such as hypernatremia, hypocalcemia and hyperphosphatemia occurred more often in NOHK group within PN 72 hours. Therefore, more use of antenatal steroid and careful control by monitoring electrolyte imbalance should be considered in order to prevent NOHK in ELBWI.

Leiomyoma is a neoplasm of smooth muscle relatively common in the stomach, but very rare in the duodenal location. Recurrent bouts of severe melana remain the most frequent presenting symptom for leiomyoma. A 69-year-old man presented to us with a 4-day history of melena. Endoscopy revealed norinal mucosa covered ovoid elevated lesion with central linear depression and ulcer at the second portion of duodenum. Endoscopic biopsy showed chronic inflammation only. Duodenal mass was excised through a duodenotomy. Pathological diagnosis was leiomycena.

OBJECTIVE: There have been conflicting reports as to whether higher rates of poor perinatal outcome carry over in cases of idiopathic hydramnios. Thus, this study was undertaken to determine whether there is any association between idiopathic hydramnios and adverse perinatal outcome. METHODS: From January 1995 to December 1999, 103 consecutive women with singleton pregnancies complicated by idiopathic hydramnios(amniotic fluid index>or=25cm) who were delivered at the Severance hospital were studied. Measured perinatal outcomes and maternal complications included preterm delivery, small for gestational age, large for gestational age, malpresentation at delivery, primary cesarean section rate, Apgar score at 5 minutes<7, admission to the neonatal intensive care unit, perinatal death, and postpartum hemorrhage. These findings were compared by means of the chi-square test, Fisher exact test, student's t-test, and logistic regression test with those of 320 control subjects with normal amniotic fluid index(5 Amniotic Fluid ; Apgar Score ; Cesarean Section ; Female ; Fetal Development ; Gestational Age ; Humans ; Infant, Newborn ; Intensive Care, Neonatal ; Logistic Models ; Polyhydramnios* ; Postpartum Hemorrhage ; Pregnancy ; Pregnancy Outcome* ; Pregnancy*

PURPOSE: To determine the effect of intraluminal brachytherapy on stent patency and survival after metallic stent placement in patients with primary bile duct carcinoma. MATERIALS AND METHODS: Twenty-seven patients with primary bile duct carcinoma underwent metallic stent placement; in 16 of the 27 intraluminal brachytherapy with an iridium-192 source (dose, 25 Gy) was the performed. Obstruction was due to either hilar (n=14) or non-hilar involvement (n=13). For statistical comparison of patients who underwent/did not undergo intraluminal brachytherapy, stent patency and survival were calculated using the Kaplan-Meier method and an independent t test. RESULTS: The mean durations of stent patency and survival were 9.1 and 10.0 months respectively in patients who underwent intraluminal brachytherapy, and 4.2 and 5.0 months in those who did not undergo this procedure (p<0.05). The mean durations of stent patency and survival among the 22 patients who died were 7.6 (range, 0.8 -16.1) and 8.3 (range, 0.8-17.3) months, respectively, in the eleven patients who underwent intraluminal brachytherapy, and 4.2 (range, 0.9-8.0) and 5.0 (range, 0.9-8.4) months in those whom the procedure was not performed (p<0.05). CONCLUSION: Intraluminal brachytherapy after stent placement extended both stent patency and survival in patients with primary bile duct carcinoma.

PURPOSE: To compare the effect of humidified high flow nasal cannula (HHFNC) with that of nasal continuous positive airway pressure (NCPAP) as the mode of extubation in very low birth weight infants (VLBWI). METHODS: Medical records were retrospectively reviewed for 219 VLBWI who were admitted to the neonatal intensive care unit of Ajou University Hospital from January 2009 through December 2012; 87 were supported by noninvasive ventilation (NIV) after extubation (HHFNC n=47, NCPAP n=40). Extubation failure was defined as the need for reintubation within 1 week of extubation. RESULTS: (1) There were no significant differences between the groups in demographic data such as gestational age, birth weight, and age at extubation. (2) There were no significant differences in fraction of inspired oxygen (FiO2) (HHFNC 0.23+/-0.03 vs. NCPAP 0.23+/-0.03, P-value .937) and peak inspiratory pressure (HHFNC 11+/-6.6 cmH2O vs. NCPAP 10.3+/-3.4 cmH2O, P-value .559) before extubation. (3) The rate of extubation failure and FiO2 values after extubation were similar in the 2 groups (extubation failure, HHFNC 5/47 vs. NCPAP 5/40, P-value 1.000; FiO2, HHFNC 0.24+/-0.05 vs. NCPAP 0.25+/-0.04, P-value .399). (4) Among patients who received NIV after extubation once but did not receive further intubation, the duration of NIV or duration of oxygen supply were not significantly different between the groups (NIV, HHFNC 12.4+/-9.1 days vs. NCPAP 8.7+/-12.3 days, P-value .159, oxygen supply, HHFNC 49.0+/-40.3 days vs. NCPAP 50.9+/-41.3 days, P-value .844) or bronchopulmonary dysplasia rate (HHFNC 24.3% vs. NCPAP 34.4%, P-value .430). CONCLUSION: HHFNC is as effective as NCPAP for weaning VLBWIs from invasive mechanical ventilation.

PURPOSE: Radiofrequency ablation (RFA) of lung cancer in animals and humans has been described in previously published reports. The aim of this study was to present our preliminary experience of treatment of lung cancer involving this approach. MATERIALS AND METHODS: Eight patients with lung malignancies [stage IIIB or IV bronchogenic adenocarcinoma (n=6), metastatic squamous cell carcinoma (n=1), metastatic hepatocellular carcinoma (n=1)] underwent RFA treatment. In all cases LeVeen-type electrodes were employed and CT was used to monitor the procedure. One-day and one-month follow-up CT scans were obtained and analyzed. RESULTS: Prior to treatment, tumor diameter ranged from 2.5 to 5 cm; afterwards, low attenuation consistent with coagulative necrosis was observed. Complications included a small amount of pneumothorax (n=4), pleural effusion (n=8), and subcutaneous emphysema (n=1). Tumor size decreased in five patients, was unchanged in two, and increased in one. CONCLUSION: Radiofrequency ablation of lung cancer is safe and may result in a reduced tumor burden.
