BACKGROUND: Noninvasive estimation of pulmonary artery pressure is an important component of echocardiographic studies. A number of methods are available for estimation of pulmenary pressure, each with varying degrees of reported accuracy. To assess accuracy and difficulties, noninvasive pulmonary artery pressure estimates were performed in infants and children with congenital heart diseases. METHODS: Noninvasive estimates from 8 methods were compared with catheterization measurements. Systolic pressure was estimated by the Burstin method and from perak tricuspid regurgitation velocity, and also from systolic pressure gradients through the VSD(ventricular septal defect) and PDA(patent ductus arteriosus). Mean pressure was estimated by acceleration time divided by ejection time measured from Koppler spectrum obtained at the right ventricular out flow tract. Diastolic pressure was estimated from pulmonary regurgitation velocity spentrum at end-diastolic, and also from diastolic pressure gradient through the patent ductus arteriosus. RESULTS: IN systolic pressure, Burstin and tricuspid regurgitation velocities estimates correlated significantly(r=0.92, 0.90 respectively), whereas VSD and PDA estimates correlated less well with catheterization estimates(r=0.83, 0.65 respectively). The mean pressure, measured from RVOT(right ventricular outflow tract) Doppler spectrum corresponded well with catheterization pressure(r=0.89), whereas those obtained from the main pulmonary artery correlated less well(r=0.74). The diastolic pressure estimates from pulmonary regurgitation velocity spectrum, revealed good correlation(r=0.79), but those from diastolic Doppler spectrum at PDA correlated less well with catheterization estimates(r=0.63). CONCLUSION: All of eight Doppler echocardiographic methods seemed to be easily performable for estimation of pulmonary artery pressure. But, the degree of accuracy was variable. Because a pressure estimante from only a single method may be in error, care should be taken in combining use of other(one or two) methods.

Cytomegalovirus (CMV) is a major cause of morbidity and mortality in immunocompromised patients. CMV can cause pneumonia, retinitis, gastrointestinal ulcers, and widely disseminated disease, but cutaneous CMV is rare. We report two cases of cutaneous CMV infection presenting as perianal ulcers. A 54 year-old male who had liver transplantation and a 72-year-old male, who was treated with chemotherapy for angioimmunoblastic T-cell lymphoma, presented with perianal ulcers and had systemic symptoms of CMV infection with CMV antigenemia. They had multiple ulcerations with erythematous bases on the perianal area, and histopathologic examinations showed large atypical cytomegalic cells in the dermis, and immunohistochemical stains, with the anti-CMV antibody showed positive reactions.

BACKGROUND: This study was aimed to assess the level of knowledge on the disinfection among nurses in the hospital. METHODS: Data was collected from the nurses who participated in an educational meeting of Korean Association of Infection Control Nurses for two days from July 7 to 8 in 2000. Seventy nurses (58.3%), among 120 participants. were answered to the 32 item questionnaire which was developed to test the level of knowledge in different types of disinfection. The correct answers for each item were computed and the rate of the total correct answer was dichotomized and compared at the level of 60% correct answer to identify the respondent's characteristics which affect the knowledge on the disinfection. RESULTS: The percent of the correct answer was 60.0% in total. 63.4% for the disinfectants general; 59.4% for the disinfection of skin: 57.6% for the disinfection of devices: 63.9% for the disinfection of endoscopies, and 55.1% for the disinfection of environments. The percent of correct answer was significantly higher among the nurses who participated in the educational programs on the disinfection previously (p=0.006), as well as the nurses who are at the infection control office or at the quality improvement department compared to other areas in the hospital (p=0.001). CONCLUSIONS: This study indicates that the level of knowledge about the disinfection was low with only 63% of the correct rate in total. We perceive that more educational programs and manuals on the use of disinfectants in a hospital setting is urgently required.

PURPOSE: We designed this study to identify and suggest the reasonable timing of adjuvant radiotherapy in the treatment of uterine carcinosarcoma according to the surgical intent and patterns of progression. MATERIALS AND METHODS: We retrospectively analyzed a total of 50 carcinosarcoma patients diagnosed between 1995 and 2010. Among these 50 patients, 32 underwent curative surgery and 13 underwent maximal tumor debulking surgery. The remaining five patients underwent biopsy only. Twenty-six patients received chemotherapy, and 15 patients received adjuvant radiotherapy. RESULTS: The median follow-up period was 17.3 months. Curative resection (p < 0.001) and stage (p < 0.001) were statistically significant factors affecting survival. During follow-up, 30 patients showed progression. Among these, eight patients (16.0%) had loco-regional progression only. The patients who had received adjuvant radiotherapy did not show loco-regional progression, and radiotherapy was a significant negative risk factor for loco-regional progression (p = 0.01). The time to loco-regional progression was much earlier for non-curative than curative resection (range, 0.7 to 7.6 months vs. 7.5 to 39.0 months). CONCLUSION: Adjuvant radiotherapy in the treatment of carcinosarcoma might be related to a low loco-regional progression rate. Radiotherapy should be considered in non-curatively resected patients as soon as possible.

BACKGROUND: The self-inflating bag-valve resuscitator is an useful breathing support equipment in the cardiopulmonary resuscitation, the transportation of patients who required ventilation assist, or respiratory therapy. The inspiratory oxygen concentration (FiO2) or tidal volume (VT) delivered to the patient depends on various conditions during bag-valve ventilation. METHODS: During bag-valve ventilation without a reservoir at oxygen flow rates of 10 l/min, we evaluated fifty six volunteers to determine the FiO2 and VT at ventilatory frequencies of 10, 12 and 15 cycles per minute and to observe the effect of hand size and grasp power on FiO2 and VT in two-hand compression methods. RESULT: The FiO2 at frequency of 10 cycles/min were 50.1% and it was higher than other ventilatory frequencies. However, the VT was not statistically different among the changes of ventilatory frequency. In the change of VT according to characteristics of the hand, the operator's hand size exerted influence on VT(larger vs. smaller ; 942ml vs. 885ml, p<0.05), but the grasp power of the hand did not significantly affect. Separate analyses with size or grasp power of the hand failed to reveal significant differences of the FiO2. CONCLUSION: The results suggest that a slowing of ventilatory frequency within the allowable ranges for adequate gas exchange increase the FiO2 during bag-valve ventilation without reservoir, and that hand size may exert influence on the VT without FiO2 changes but grasp power may not be a contributing factor to the VT or FiO2 changes.

7.Chronic Pancreatitis Associated with Liver Infarction and Inferior Pancreaticoduodenal Artery Pseudoaneurysm.
Korean Journal of Pancreas and Biliary Tract 2017;22(1):35-38
Liver infarction is rare because of dual blood supply of the liver with hepatic artery and portal vein. And its occurrence as a complication of chronic pancreatitis is rarer. We present a case of chronic pancreatitis complicated by liver infarction and inferior pancreaticoduodenal artery pseudoaneurysm. A 31-year-old female with alcoholism presented with severe acute epigastric pain. Serum amylase and lipase were 203 IU/L and 78 IU/L, respectively. Initial computed tomography (CT) scan showed peripancreatic infiltration, fluid collection, right portal vein thrombosis, and a large wedge-shaped low attenuation in the right hepatic lobe. The patient has been treated with heparin. Follow-up CT scan done after 4 days of heparin treatment demonstrated a pseudocyst with internal hemorrhage and a pseudoaneurysm. Angiography revealed a pseudoaneurysm in inferior pancreaticoduodenal artery. Coil embolization of the artery was done. The patient has been discharged without complication. Follow-up CT scan showed resolution of liver infarction, portal vein thrombosis and pseudoaneurysm.

OBJECTIVE: The goal of this study is to determine the efficacy of rapid karyotyping from fetal ascitic fluid. METHODS: In three cases of isolated fetal ascites diagnosed by prenatal ultrasonography, ultrasound guided fetal paracentesis and amniocentesis were performed and successfully obtained. Fetal karyotyping in each case at 29, 30 and 32 weeks gestation using modified lymphocyte culture method was conducted. RESULTS: The chromosomal analysis was successful within 72 hours and abnormalities were detected in two cases and revealed trisomy 21 in each case. Our study demonstrated that the majority distribution of white blood cells was lymphocytes which ranged from 2.1 * 10(6) cells/ml to 3.7 * 10(6) cells/ml and the cell density for culture was at least than 0.35 * 10(6) cells/ml. CONCLUSION: The use of ascitic fluid as a cell source to achieve rapid fetal karyotyping can be valuable when cordocenteis or amniocentesis would be technically more difficult, or when rapid result is required for planning of perinatal management at late second or third trimester gestational age.

10.Clinical Results and Optical Quality of Diffractive Multifocal Intraocular Lens.
Journal of the Korean Ophthalmological Society 2015;56(12):1867-1873
PURPOSE: To compare postoperative clinical outcomes, optical quality, and patient satisfaction between two types of diffractive multifocal intraocular lens (IOL, Acri Lisa 366D and Acrysof ReSTOR +3.00 D). METHODS: In a total of 68 eyes, one of two diffractive multifocal IOL (Acri Lisa 366D and Acrysof ReSTOR +3.00 D) was implanted after cataract extraction. Visual acuity was measured postoperatively at one week, 1 month, and 6 months. Contrast sensitivity, wavefront aberration, and visual function were determined via questionnaire at postoperative 1 month. RESULTS: Intermediate visual acuity of Acri Lisa 366D and Acrysof ReSTOR at 6 months were 0.31 +/- 0.14, and 0.24 +/- 0.11 (log MAR), respectively. At 6 months, near and distant visual acuity results showed no significant differences between the two groups. The photopic contrast sensitivity of Acri Lisa 366D at 6 cycles/degree was 55.36 +/- 7.40 and showed significant differences with Acrysof ReSTOR (47.25 +/- 9.67). The mesopic contrast sensitivity values of Acri Lisa 366D and Acrysof ReSTOR were 40.26 +/- 11.38 and 28.97 +/- 10.45, respectively, and the spherical aberration values were 0.037 +/- 0.039 microm and 0.105 +/- 0.066 microm. The spherical aberration of Acri Lisa 366D was significantly lower than that of Acrysof ReSTOR. Total and high order aberration, coma, and trefoil show no significant differences between the two groups. CONCLUSIONS: The Acri Lisa 366D multifocal IOL showed better contrast sensitivity and spherical aberration compared to Acrysof ReSTOR multifocal IOL, which had an effective intermediate visual acuity.
