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.

Neurilemmoma is well-encapsulated tumor of Schwann cell origin. The majority arise in peripheral nerve or cranial nerve, and rare in retroperitoneum. Although it is incidentally detected by the advances in diagnostic procedures, especially in ultrasound and computed tomography, it is confirmed by pathologic findings. The treatment is surgical excision. We report a case of retroperitoneal neurilemmoma arising from adjacent to adrenal gland, in 45 years old female.

Continuous renal replacement therapy (CRRT) has become the preferred dialysis modality to support critically ill children with acute kidney injury. As CRRT technology and clinical practice advances, experiences using CRRT on small infants and neonates have increased. In neonates with hyperammonemia or acute kidney injury during extracorporeal membrane oxygenation (ECMO) therapy, CRRT can be a safe and effective technique. However, there are many limitations of CRRT in neonates, including vascular access, bleeding complications, and lack of neonate-specific devices. This review discusses the basic principles of CRRT and the special considerations when using this technique in neonates and infants.

Renal angiomyolipoma is composed of mature fats, smooth muscles and abnormal blood vessels which arises mainly from renal parenchyme and compresses the calyx or protrudes the renal cortex, but which extends into the renal cyst is rare. Recently it can be easily diagnosed preoperatively by several diagnostic modalities such as ultrasonography, computed tomography and several clinical signs associated with tuberous sclerosis, although it`s clinical and radiological features are similar with renal cell carcinoma. We report a case of renal angiomyolipoma without tuberous sclerosis, extending into the renalcyst, which was confused with renal pelvis tumor in a 73 years old male.

A clinical evaluation was made on 19 patients with urethral stricture following urethral catheterization in 155 urethral stricture patients during 12 years from January. 1979 to December. 1990. The following results were obtained. I. In 155 cases of urethral stricture, iatrogenic urethral stricture was 24 cases (15.4%) of which the most common cause was urethral catheterization(19 cases) and followed by instrumentation (2 cases). 2. In 19 cases of urethral stricture following urethral catheterization. the most common site was the anterior urethra (bulbous 10 cases. pendulous 7 cases) and multiple strictures showed 5 of 17 anterior urethral strictures. 3. In 19 cases, 16 cases (84.2%) occurred in patients who have kept the urethral catheter within seven days and 18 cases (94.7%) were inserted and cared the urethral catheter by non-urologist. 4. Treatment was performed internal urethrotomy in 16, dilatation in 2 and catheter indwelling during 1 week in 1. 5. In 24 cases of iatrogenic urethral stricture. mean number of dilation to recurrent strictures after primary procedure had required O.5 time. From our results. we suggest that education for the careful insertion and method of care for the urethral catheter to non-urologist is least likely to induce urethral stricture formation.

A rare case of giant invasive intraosseous schwannoma in lumbar vertebra with no neurologic deficit is reported. This tumor had vertebral body, left paravertebral tissue and lamina invasion and thus classified as type V giant invasive schwannoma according to Sridhar's classification of benign nerve sheath tumor. Because intraosseous portion was significantly larger than extraosseous portion, this tumor was mentioned as intraosseous schwannoma. Tumor was successfully resected using corpectomy, mesh cage insertion and posterior fixation. Pathological diagnosis was benign schwannoma.

STATEMENT OF PROBLEM: The clinical criteria of soft lining materials are resilience over an extended period, capability of forming a strong bond with denture base materials, dimensional stability, adequate tear strength, and color stability. Many researches and reports dealt with food colorants or denture cleanser, but not with fermented foods. PURPOSE: This study was designed to assess what fermented foods, such as soy sauce and red pepper paste that many Koreans have eaten, influence on the color stability of soft denture liners. MATERIAL AND METHODS: The color differences(delta E*) were measured by spectrophotometer with different immersion time. For the procedure, thirty disk-shape specimens per 4 soft denture liners(Molloplast-B(R), Ufi Gel SC(R), Dura Base(R), Sofreliner MS(R)) were fabricated with a thickness of 2mm and 16mm in diameter. Each 10 specimen were immersed into the beakers of fermented foods and distilled water, and L*, a*, and b* values were measured for the color difference(delta E*), on the 1st, 7th, and 28th day with spectrophotometer. RESULT AND CONCLUSION: 1. There were significant differences between samples(soy sauces, red pepper pastes, and distilled water) in Sofreliner MS(R) of 1st day after immersion(p<0.05). There were significant differences between samples in Sofreliner MS(R) and Ufi Gel SC(R) of 7th days after immersion(p<0.05). There were significant differences between samples in Molloplast-B(R) of 28th day after immersion(p<0.05). 2. In red pepper pastes, delta E* values of Molloplast-B(R), Ufi Gel SC(R), Sofreliner MS(R) were higher than 3.3. Those values were not clinically acceptable. In soy sauces, delta E* values of all denture liners were lower than 3.3. delta E* values of Ufi Gel SC(R) were higher than those of other denture liners. 3. Based on the above results, red pepper paste causes more discoloration than soy sauce.
