BACKGROUND: The influenza is a contagious respiratory illness caused by influenza viruses. The primary target groups recommended for annual vaccination are healthcare workers and households which have frequent contact with persons at high risk and can transmit influenza to those persons at high risk. Members of these groups should be vaccinated against the flu so that they can avoid getting infected with continuously mutating influenza viruses. We assessed healthcare workers' knowledge and attitudes regarding influenza vaccination in order to help promote the vaccination rate. METHODS: This survey was carried out in two hospitals affiliated with the Catholic University School of Medicine, from December 2004 to January 2005. Of the 3,023 questionnaires distributed, 2,023 could be evaluated. RESULTS: The most frequently cited reason for receiving influenza vaccine was self-protection against influenza (55.4%). The most common reasons for not receiving influenza vaccine are personal health problems such as concurrent flu, pregnancy or breast-feeding (29.2%). There is no significant difference in the frequency of side effect between two groups receiving and not receiving vaccine. The most frequent side effect of influenza vaccination is flu-like syndrome; People receiving vaccine have more significant knowledge than those people not receiving vaccine about efficacy of flu vaccination, risk of influenza infection of healthcare workers and their need of flu vaccination. CONCLUSION: In order to promote the vaccination rate, education targeting people at high risk need to keep continuous and facilitate access to vaccination.

BACKGROUND: Serratia marcescens proliferates well in a humid environment or soil and is recently considered as an important pathogen for the severe nosocomial infections. this organism is spreads easily by hand-to-hand transmission, and contaminates medical equipment used for invasive procedures, working environment, medications, and soap. METHODS: We investigated the source of an outbreak of bloodstream infections by S. marcescens isolated that occurred during the period from July to December, 2004, at a university hospital in Gyeonggi Province and attempted to intervene in the outbreak and control it. RESULTS: From July to December, 2004, S. marcescens grew from 296 blood culture from 283 patients. The medical charts of the patients were reviewed, and surveillance cultures were taken to identify the outbreak of nosocomial infections and risk factors. Only four cases of infection were identified and all remaining positive blood cultures were due to contamination. Nine isolates randomly selected from the 296 S. marcescens showed an identical pulsed-field gel electrophoresis pattern. To identify the source of infection, environmental culture and hand cultures of the related medical workers were carried out, but S. marcescens was not isolated. CONCLUSION: As the result of aggressive infection control activities, such as re-education on environmental management methods, hand washing techniques, and blood culture sampling techniques, no more S. marcescens had been grown in blood culture since January, 2005.

Background and Objectives:
Blood pressure (BP) measurement using an auscultatory sphygmomanometer is recommended for diagnosing hypertension in children. As mercury sphygmomanometers (MSs) are banned owing to environmental concerns, it is crucial to determine the accuracy of mercury-free sphygmomanometers to replace them. We analyzed the accuracy of these devices to guide the National Survey selection.
Methods:
BP was measured thrice each with MS, auscultatory device (AD), and oscillometric device (OD) in 104 participants aged 10–18 using the National Survey data. The difference in BP was defined as the difference between MS and other devices. The BP differences, correlations, and influencing factors were analyzed. The frequencies of hypertension were also compared.
Results:
Systolic BP (SBP) and diastolic BP (DBP) differences between MS and AD were 0.88±3.36 mmHg and 0.63±3.95 mmHg, and those between MS and OD were 0.43±5.83 mmHg and 4.57±6.89 mmHg, respectively. The absolute error of <10 mmHg for DBP between MS and OD was 76%. The concordance correlation coefficient between MS and AD was 0.94 for SBP and 0.90 for DBP, and 0.81 and 0.67, respectively for MS and OD. Arm circumference negatively correlated with BP differences except for SBP between the MS and OD. The frequency of hypertension was not different between MS and AD but was underestimated by OD.
Conclusions
AD correlated well with MS, while OD did not, especially for DBP. The superiority of AD over OD suggests AD as a possible alternative for MS in the National Survey.

Most intracranial schwannomas originate from the cranial nerve especially CN V, VIII. However, schwannomas from low-cranial nerve are rarely reported. We report a case of large foramen magnum schwannoma in a 26 year-old-man presenting swallowing difficulty, nausea and vomiting. Magnetic resonance image revealed a cystic multilobulated huge mass from midclivus to atlas which compressed brain stem. The mass was removed by far-lateral transcondylar approach and confirmed with schwannoma which originated from hypoglossal nerve.

A differential diagnosis between neurosarcoidosis and neurosyphilis is particularly problematic in patients with a positive serologic result for syphilis. We report here a patient with a solitary cavernous sinus sarcoidosis who had a history of syphilis and showed rapidly progressing cavernous sinus syndrome. A transsphenoidal biopsy was performed and a histopathologic examination revealed a non-caseating granuloma with an asteroid body. His facial pain disappeared after steroid therapy. He received oral prednisolone for one year. A follow-up magnetic resonance imaging of the brain revealed resolution of the mass over the cavernous sinus. Particularly in patients with a history of syphilis, neurosyphilis should be included in a differential diagnosis of neurosarcoidosis.

PURPOSE: Epidormoid cysts are benign epithelial cysts often ocurring within the skin of face and trunk. But carcinomatous change is rare. The authors experienced a case of squamous cell carcinoma arising from the wall of epidermoid cyst of axilla and report the radiologic and pathologic findings with a brief review of the literatures. METHODS AND MATERIALS: Plain chest radiograph, US and enhanced CT of axilla were takened. We analyzed radiologic findings of squamous cell carcinoma in the wall of epidermoid cyst of axilla and correlated with pathologic findings. RESULTS: Plain chest radiograph revealed a huge axiilary mass without bony destruction or calcification. showed a heterogenous hyperechoic mass with eccentrical cystic lesion. Outer margin of the mass was irregular. No posterior acoustic enhancement was seen. Postcontrast CT scan showed a circumscribed complex mass with irregular enhancing rim. During operation mass was located within subcutaneous layer and internal contents of the mass were brown, necrotic keratinous debries. CONCLUSION: Differentiation from solid tumor was difficult. But intradermal or subcutaneous location and rapid growing were characteristic.

BACKGROUND: Urinary trypsin inhibitors (UTI) have been widely used for the treatment of diseases including disseminated intravascular coagulation, shock, and pancreatitis. Since UTI synthesis is likely to be reduced in patients who have undergone liver resection, the incidence of inflammatory reactions may be increasing accordingly. For such patients, the liver enzyme increases after the operation can reflect liver damage. The purpose of this study was to examine if ulinastatin can inhibit liver enzyme increases after liver resection. METHODS: After receiving Institutional Review Board approval, a retrospective chart review was performed on 201 patients who underwent hepatic resection from 2006 to 2010. We divided the records into the control (n = 69) and ulinastatin (n = 132) groups according to the use of intraoperative ulinastatin and compared the preoperative and postoperative laboratory test results. The number of patients who had > 400 U/L elevation of aspartate transaminase (AST) level after surgery was compared between the 2 groups. RESULTS: The mean AST, alanine transaminase (ALT), and total bilirubin levels after liver resection were significantly lower in the ulinastatin group than in the control group. The number of patients who showed an AST > 400 U/L after liver resection was significantly higher in the control group (odds ratio = 3.02). CONCLUSIONS: Ulinastatin attenuates the elevation of hepatic enzymes and bilirubin after liver resection.

The aim of this study is to determine whether full-mouth disinfection therapy(FMT) in our clinical setting would show better improvement of clinical parameters than partial mouth disinfection therapy(PMT) in chronic periodontitis and aggressive periodontitis patients. Among 12 patients, 6 were treated FMT and other 6 were treated PMT. Clinical parameters were calculated 3 months and 6 months after initial therapy. 1. There were no statistically significant differences between FMT and PMT in the reduction rate of bleeding on probing after 3 months, 6 months 2. Initial probing depth was 4-6mm, the mean probing depth after 3 months was 2.2mm vs 2.5mm(FMT vs PMT), after 6 months was 2.4mm vs 2.8mm. This was significantly lower in the FMT groups. 3. Initial probing depth was > or = 7mm, the reduction rate of mean probing depth during first 3 months was 4.8mm vs 4.1mm(FMT vs PMT), and 3 to 6 months was 0.5mm vs 0.3mm. This was significantly larger in the FMT groups. 4. Initial probing depth was 4-6mm, the mean clinical attachment level after 3 months was 2.3mm vs 2.7mm(FMT vs PMT), after 6 months was 2.7mm vs 3.0mm. This was significantly lower in the FMT groups. 5. Initial probing depth was > or = 7mm, the reduction rate of mean probing depth during first 3 months was 4.0mm vs 3.0mm(FMT vs PMT), and 3 to 6 months was 0mm vs -0.1mm. This was significantly larger in the FMT groups. Although the results provided us with succeccful clinical improvement in aggressive periodontitis, further research is needed to prove its additional benefit in the treatment of chronic periodontitis
