BACKGROUND: Malpositioning of the endotracheal tube within airway after intubation may results in serious complications, such as accidental extubation and inadvertent endobronchial intubation. Therefore, early detection of malposioning of the endotracheal tube is very impotant for deciding patient's prognosis. METHODS: We assessed the distance from the tip of the endotracheal tube to the carina according to the patient's age, sex, and the time, the location, and the route of intubation. The chest x-ray was taken for 333 patients (men, 226: women, 107) who were admitted to the intensive care unit of Wonju Christian Hospital from march 1, 1995 to February 28, 1996. Chest x-ray was obtained after intubation to verify endotracheal tube position. Appropriate endotracheal tube position on chest x-ray was defined as between 2 and 6 cm above the carina. RESULTS: Of the 333 intubations, 106 (31.8%) endotracheal tubes were inappropriately placed according to the chest x-ray. The percentage of malpositioned endotracheal tubes (<2 cm) was higher in women than in men (11.2% vs. 5.3%, p<0.05), with higher in night (7 PM to 7 AM) than in day (7 AM to 7 PM) (42% vs. 24%, p<0.05). Distance from the carina to the tip of endotracheal tube is 4.34 +/- 1.77cm in women and 5.23 +/- 1.64cm in men. Thus, position of the endotracheal tube in women is deeper than men (p<0.001). CONCLUSIONS: We conclude that the chest x-ray for confirmation of endotracheal tube position after endotracheal intubation may remain the standard of practice. And endotracheal tube position should be carefully assessed immediately after tracheal intubation, particularly in women and at night.

OBJECTIVES: Leptin is a 16-kD protein encoded by the ob/ob gene and represent the amount of body fat. In pregnancy, it is thought to act in intrauterine fetal growth and energy metabolism. In this study, we investigated the effect of gestational age, fetal sex, maternal body mass index (BMI), and fetal weight estimated by ultrasound on amniotic fluid and maternal serum leptin levels at mid-trimester, respectively. METHODS: Amniotic fluid and maternal blood sampling were collected from women who was performed for genetic amniocentesis at mid-trimester (n = 26). Leptin concentrations were measured by a specific radioimmunoassay (RIA) employing human recombinant leptin. Mean gestational age was 18.19+/-1.77 weeks. Mean maternal BMI was 23.83 +/-5.12kg/m2. Male fetus was 10, and female 16. Mean fetal weight estimated by ultrasound was 254.42+/-83.80gm. RESULTS: Mean maternal leptin level( 12.49+/-4.46 ng/mL) was significantly higher than mean amniotic leptin level(5.06+/-3.20 ng/mL)( p = 0.0001) at mid-trimester. But there was no significant correlationship between maternal and amniotic leptin levels( p = 0.1376). Maternal leptin concentrations at mid-trimester were correlated positively with maternal BMI(y = 2.24 + 0.43 x, R2 = 0.494, p = 0.0103). In contrast, leptin levels in amniotic fluid did not correlate with maternal leptin levels, gestational age, fetal sex, maternal BMI, and fetal weight estimated by ultrasound respectively. CONCLUSION: Maternal leptin level was higher than amniotic leptin level and could represent maternal fat mass. It was suggested that amniotic leptin level was not associated with several factors such as maternal, fetal, and amniotic factors.

BACKGROUND: Antimicrobial resistance (AMR) is an issue not only with regard to public health, but also in terms of economic impact. AMR surveillance has mainly been carried out in general hospitals, and not in nursing hospitals. This study was conducted to investigate the AMR rate for bacterial strains isolated from nursing hospital samples.METHODS: Antimicrobial susceptibility testing (AST) results from a total of 23,518 bacterial isolates recovered from clinical specimens taken in 61 nursing hosals were analyzed. AST was conducted using Vitek 2 with AST cards specific for the bacterial strains.RESULTS: A total of 19,357 Gram-negative and 4,161 Gram-positive bacterial strains were isolated. Pseudomonas aeruginosa (n=6,384) and Escherichia coli (n=5,468) were the most prevalent bacterial species and, among Gram-positive bacteria, Staphylococcus aureus (n=1,565) was common. The AMR rate was high for the following strains: cefotaxime-resistant Klebsiella pneumoniae, 77.4%; cefotaxime-resistant E. coli, 70.6%; imipenem-resistant Acinetobacter baumannii, 90.3%; imipenem-resistant P. aeruginosa, 49.3%; oxacillin-resistant S. aureus, 81.1%, penicillin-resistant Enterococcus faecalis, 44.8%, and vancomycin-resistant Enterococcus faecium, 53.5%. AMR rate change varied by bacterial species and antimicrobial drug.CONCLUSION: AMR rates of major pathogens from nursing hospitals were higher than those from general hospitals with the exception of imipenem-resistant A. baumannii. Continuous monitoring and infection control strategies are needed.

PURPOSE: Given the emerging evidence for differential responses to new targeted therapies and the identification of molecular differences between specific subtypes of non-small cell lung carcinoma (NSCLC), there is an increased need for greater accuracy in subtyping NSCLC. In a substantial proportion of cases, standard morphology cannot specifically subtype the tumor, resulting in a final diagnosis of NSCLC-not otherwise specified. In this study, we added newly proposed markers (napsin A, desmocollin-3) to conventional markers (p63, thyroid transcription factor-1 [TTF-1], cytokeratin 5/6 [CK5/6], high molecular weight cytokeratin [HMWCK], cytokeratin 7 [CK7]) and evaluated for the minimal panel of immunohistochemical markers required for subtyping poorly differentiated (PD) NSCLC. MATERIALS AND METHODS: Resection specimens of 110 adenocarcinomas (ADCs) and 171 squamous cell carcinomas (SCCs) were collected and tissue microarrays were constructed to simulate small biopsy conditions. All specimens were stained with TTF-1, napsin A, CK7, p63, CK5/6, HMWCK, desmocollin-3 and mucicarmine. RESULTS: For 32 PD ADC, a combination of TTF-1 and napsin A increased sensitivity (81%). With regard to the 29 PD SCC, a combination of desmocollin-3 and p63 did not substantially increase diagnostic performance. Logistic regression analysis identified napsin A, p63 and TTF-1 as the optimal panel to separate PD ADC and PD SCC. Mucin stains for PD NSCLC increased accuracy rate (88%) for diagnosis of PD ADC. CONCLUSION: We recommend a minimal panel of immunohistochemical and histochemical markers to include TTF-1, p63, napsin A and one of mucin stains for tumor subtyping of PD NSCLC in a small biopsy sample.

Capsule endoscope is self-contained videoendoscopy device that transmit images of the gastrointestinal tract to an external receiver. Capsule endoscopy has become a very important tool for diagnosing of small bowel disorders. Upcoming capsule endoscopy techniques for the investigation of esophageal, stomach, and colon may render it promising technique for these organs as well. This document is intended to provide the principles by which credentialing organizations may create practical guidelines for granting privileges to perform capsule endoscopy. KSGE recommends that the use of capsule endoscopy be limited to practitioners already competent and privileged to perform standard upper and lower endoscopy and who have extensive experience viewing gastrointestinal mucosa. KSGE recommends additional specific training in capsule endoscopy as well as review of the 20 procedures to verify competence. KSGE also admitted formal fellowship training having a familiarity with the hardware and software systems and interpretation of the at least 10 cases under the supervision of professor in capsule endoscopy during GI fellowship.

Malignant germ cell tumors of the ovary are uncommon neoplasms. Although 20-25% of all ovarian tumors are derived from germ cells, only about 3% of germ cell tumors are malignant. Mixed germ cell tumors contain at least two malignant germ cell elements. These lesions should be managed with combination chemotherapy, preferably BEP. Recently we experienced a case of mixed germ cell tumor with 6 components of germ cell and sarcomatous change in a 11 year old girl. Preoperative CA-125, B-hCG, aFP, LDH, a-1-antitrypsin were elevated and the final pathologic report was mixed germ cell tumor composed of endodermal sinus tumor, embryonal carcinoma, mature and immature teratoma, choriocarcinoma, dysgerminoma and sarcomatous change, Postoperative chemotherapy with 6 courses of BEP regimen was performed and all tumor markers became normal after 4 courses of chemotherapy. What we interested in this case was several components of germ cells and sarcomatous change and the sarcomatous change might be derived from the mature cystic teratoma component, so we present this case with a brief review of the literatures here.

PURPOSE: The purpose of this study was to understand the principle of percutaneous nephrolithotomy(PNL), toincrease its success rate, and to base the radiologic approach on preoperative interventional tract dilatation. MATERIALS AND METHODS: Twenty-six patients(male, 19, female, 7) with staghorn or pelviocalyceal calculi who hadundergone PNL were included in this study. After percutaneous nephrostomy(PCN) was performed in each patient, thetract was dilated to 30F with Amplatz dilators using coaxial techniques or a 30F, 10cm high-pressure tractdilatation balloon. One day before the calculi were fragmented and removed by PNL, a 30F Amplatz sheath wasinserted under local anesthesia. The time required for tract dilatation, complications, and surgery was analyzed. RESULTS: Percutaneous tract dilatation were successful in all patients, and forceps, a nephrolithotome and anephroscope were successfully introduced into the pelvocalyceal system. The average procedure time was 19.5minutes ; a double J stent was replaced in the pelvocalyceal system of 13 of 26 patients (50%) ; because ofimproper catheter direction or/and bleeding, the Amplatz sheath was replaced in three. After PNL, complicationsinvolving renal hematoma occurred in one patient. This did not affect the patient's prognosis, however. CONCLUSION:Owing to its short procedure time and low complication rate, interventional preoperative tract dilatation forPNL is thought to be an effective technique for patients with staghorn or pelvocalceal calculi.
