Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

PURPOSE: This study was done to develop and test validity and reliability of on instrument for predicting nursing intention for SARS patient care. METHOD: The psychometric properties of a SARS patient care attrition prediction tool, based on the Theory of Planned Behavior, were examined in this study. The Three-phase design involved a) salient beliefs generated from clinical nurses (n=43) b) content validation by expert panel evaluations(n=5) c) face validation by plot testing (n=10) d) and instrument validation in a cross sectional survey (n=299). Psychometric analysis of survey data provided empirical evidence of the construct validity and reliability of the instrument. RESULT: Principal component analysis verified the hypothesized 6-factor solution, explaining 68.2% of variance, and Alpha coefficients of .7538 to .9389 indicated a high internal consistency of the instrument. CONCLUSION: The instrument can be used by nurse administrators and researcher to assess clinical nurses' salient beliefs about caring for SARS patients, guide tailored intervention strategies to effective caring, and evaluate the effectiveness of interventions.

BACKGROUND: Currently, the incidence of hepatitis A is on the increase in Korea. Although there is emphasis on contact precautions, the nosocomial outbreak of hepatitis A virus (HAV) in healthcare personnel has increased within endemic areas because these workers inevitably come in close contact with patients and work under suboptimal hygiene conditions. In this study, we evaluated the necessity of immunization against HAV for healthcare personnel. METHODS: We investigated the seropositivity of serum immunoglobulin G (IgG) anti-HAV antibody (Ab) in 672 healthcare personnel on the basis of their age-group, sex, and occupation in Soon Chun Hyang University Hospital and Soon Chun Hyang University Bucheon Hospital. RESULTS: The subjects were divided into 6 groups on the basis of their ages to identify differences among the various age groups in the number of cases with HAV Ab seropositivity. Significant intergroup differences were noted in this respect: 21-25 years, 2/152 (1.3%); 26-30 years, 33/245 (13.5%); 31-35 years, 70/148 (47.3%); 36-40 years, 52/79 (65.8%); >40 years, 44/48 (91.7%). CONCLUSION: The number of seropositive cases was low among young healthy personnel: low seropositivity is an emerging risk for vulnerable population. With the increase in the incidence of hepatitis A, healthcare personnel have become a risk population for hepatitis A, as are community residents. Therefore, for healthcare personnel working in hospitals, immunization against HAV should be recommended for personnel younger than 30 years, and serological testing for older personnel.

PURPOSE: To estimate the prevalence of periodontitis in Korean adults and to examine the associations between periodontitis and known risk factors. METHODS: Using Korean National Oral Health Survey 2006 data, a total of 4,263 people who had taken oral examination, interviewed by questionnaire, and aged 18 or older were sampled. The prevalence of periodontitis measured by Community Periodontal Index (CPI) was calculated and the differences in prevalence according to known risk factors (age, sex, monthly income, education, residential area, tooth-brushing frequency, regular dental visit, smoking, and diabetes) were examined with chi-square test. Logistic regression analysis was performed to see the effects of each risk factor on the risk of having periodontitis. All statistical approaches were reflected national sampling design using Survey procedures in SAS 9.1. RESULTS: The overall prevalence of periodontitis in Korean adults was 10.3%. There existed statistically significant differences in crude prevalence for periodontitis according to the all risk factors. In logistic regression, older age groups (O.R.:2.94-3.71), people living in rural area (O.R.:1.87), and current smokers (O.R.:1.77) were significantly prone to have periodontitis. People who earned monthly income of more than 2 million Korean won (O.R.:0.64) and brushed their teeth two or more times per day (O.R.:0.60-0.62) had significantly lower risk of having periodontitis. CONCLUSIONS: About 10% of Korean adults had periodontitis in 2006. People who were older, living in rural region, in lower income status, smoking, less tooth brushing were more likely to have periodontitis.

OBJECTIVE: Recently some behavioral features and affective traits are considered important for the phenotype of obsessive-compulsive disorder (OCD). The purpose of this study was to assess some specific behavioral, temperamental, emotional features of OCD patients and to investigate if there is any change in patterns of temperament-character after 4-month pharmacotherapy. METHODS: Fifty-six patients with OCD and 70 normal controls were enrolled in this study. Four self-report questionnaires were employed to assess temperamental characteristics and affective traits: The behavioral inhibition system and behavioral activation system scale, the Baratt impulsiveness scale, state-trait anger expression inventory, emotional intelligence inventory. Among 56 OCD patients, 21 subjects started pharmacotherapy and 4 months later, they repeated 4 self-report tests as the same above and Yale-Brown obsessive compulsive scale (Y-BOCS). And then we investigated the changes from initial results. RESULTS: Patients with OCD showed significantly greater expression of behavioral inhibition system (p<0.0001), more cognitive impulsiveness (p<0.0001), motor impulsiveness (p=0.0067) and increased level of state anger (p<0.0001), trait anger (p<0.0001) than healthy controls. Compared to the controls, the OCD patients also expressed significantly lower level of emotional intelligence for using to facilitate thinking (p<0.0001) and managing emotions (p<0.0001). After 4-month pharmacotherapy for 21 OCD patients, Y-BOCS scores significantly decreased while self-report tests showed no meaningful differences from baseline assessments. CONCLUSION: Our results suggest that patients with OCD may have some differences in behavioral and affective tendencies including behavioral inhibition, impulsiveness, anger experiences, and emotional patterns. And short term pharmacotherapy during 4 months improved the severity of obsessive-compulsive symptoms but didn't influence these traits. These results provide some perspectives about possible vulnerability or trait markers of OCD. Further research is needed to examine the effects of long term treatment and other investigation might be helpful to assess the relationships between these behavioral and affective aspects and clinical phenotypes of OCD.

Castleman's disease is an atypical lymphoproliferative disorder of unknown origin. It has three histologic types (hyaline vascular, plasma-cell, and mixed) and two clinical types (localized and multicentric). Some systemic diseases may be accompanied with Castleman's disease, but it is unclear if Castleman's disease is relevant to rheumatoid arthritis. We experienced a case of Castleman's disease suffering from rheumatoid arthritis. A 25-year-old female with rheumatoid arthritis was referred to our hospital with a palpable mass lesion in the left upper arm. Excisional biopsy of the mass and arthroscopic synovectomy were performed, and the histological finding was compatible with hyaline-vascular type of Castleman's disease. Herein, we report this case along with brief review of relevant literature.

BACKGROUND: Members of the Acinetobacter calcoaceticus-baumannii (Acb) complex are important opportunistic bacterial pathogens and present significant therapeutic challenges in the treatment of nosocomial infections. In the present study, we investigated the integrons and various genes involved in resistance to carbapenems, aminoglycosides, and fluoroquinolones in 56 imipenem-nonsusceptible Acb complex isolates. METHODS: This study included 44 imipenem-nonsusceptible A. baumannii, 10 Acinetobacter genomic species 3, and 2 Acinetobacter genomic species 13TU strains isolated in Daejeon, Korea. The minimum inhibitory concentrations (MICs) were determined by Etest. PCR and DNA sequencing were used to identify the genes that potentially contribute to each resistance phenotype. RESULTS: All A. baumannii isolates harbored the blaOXA-51-like gene, and 21 isolates (47.7%) co-produced OXA-23. However, isolates of Acinetobacter genomic species 3 and 13TU only contained blaIMP-1 or blaVIM-2. Most Acb complex isolates (94.6%) harbored class 1 integrons, armA, and/or aminoglycoside-modifying enzymes (AMEs). Of particular note was the fact that armA and aph(3')-Ia were only detected in A. baumannii isolates, which were highly resistant to amikacin (MIC50> or =256) and gentamicin (MIC50> or =1,024). In all 44 A. baumannii isolates, resistance to fluoroquinolones was conferred by sense mutations in the gyrA and parC. However, sense mutations in parC were not found in Acinetobacter genomic species 3 or 13TU isolates. CONCLUSIONS: Several differences in carbapenem, aminoglycoside, and fluoroquinolone resistance gene content were detected among Acb complex isolates. However, most Acb complex isolates (87.5%) possessed integrons, carbapenemases, AMEs, and mutations in gyrA. The co-occurrence of several resistance determinants may present a significant threat.

Retrorectal tumors are particularly rare among the adult population, occurring in 1 of 40,000 hospital admissions. Clinical diagnosis is difficult and is often delayed because of vague symptoms. This study aimed to investigate the clinicopathological features of retrorectal tumors. Between January 1999 and March 2005, 10 patients were diagnosed with retrorectal tumors at the Department of Surgery, Yonsei University Medical Center, and their medical records were reviewed. We analyzed chief complaints, imaging studies, surgical approaches and pathologic examinations. Out of 10 patients, 8 were female and 2 were male. The mean age was 42.8 years. Four patients had no symptoms. Perianal and abdominal pain were the most common presentations. CT and MRI were the most frequently performed imaging studies. Surgery was performed in 9 patients. Postoperative pathologic diagnosis was possible in 9 patients. An epidermal cyst was the most common tumor (4 patients); others included a mature teratoma, an adenocarcinoma from a tail gut cyst, a duplication cyst, a neurogenic tumor, and a smooth muscle cell tumor. Imaging techniques like CT scans, MRI and TRUS are helpful to determine the size and the extent of a tumor and its relationship to the surrounding anatomical structures for the operative approach. A surgical resection is the standard of treatment and demonstrates good results and a good prognosis.
