We present two cases of pseudocyst of auricle which occured in 59-year-old man and 21-year-old man. Each showed bean sized non-inflammatory cystic swelling of upper part of right auricle with slight tenderness and the cystic content was serosanguinous fluid. Cystic wall was composed of fibrovascular tissue replacing degenerated cartilage without lining epithelium.

OBJECTIVES: Outbreaks of pneumonia caused by Mycoplasma pneumoniae (MP) occur every 3-4 years in Korea, most recently in 2011. The aim of our study was to determine the optimal time to perform indirect particle agglutination antibody assays to improve early diagnosis of MP pneumonia in children. METHODS: A database of 206 pediatric patients treated for pneumonia at the Hanyang University Hospital from June to October 2011 was analyzed retrospectively for demographic characteristics and laboratory test results. RESULTS: Among the 206 patients treated for pneumonia during the study period, there were 160 children (mean age, 5.44 years) diagnosed with MP pneumonia, who were studied further. The mean age of these MP pneumonia patients was 5.44 years. Antibody titers increased with increasing time between symptom onset and the collection of serum collection: MP titers were <1:640 for sera collected after 5.44 days and titers > or =1:640 for those collected after 8.58 days; P<0.001). Antibody titers were considered positive when they reached > or =1:640. In 42 MP pneumonia patients in whom there was a four-fold or greater increase in titer between successive serum samples, the optimal cut-off time-point for distinguishing between the initial and second titer groups was 7.5 days after the onset of symptoms (sensitivity, 90.5%; specificity, 92.9%). CONCLUSIONS: Negative MP antibody titers earlier than 8 days after the onset of symptoms in children with pneumonia may require repeating to confirm the diagnosis. This finding could optimize diagnosis and result in better therapeutic outcomes of MP pneumonia in children.

A case of pigmented villondular synovitis is reported in a 32 years old woman, who exhibited bulbulous supra-patellar bulging with dull pain on the right knee joint. Aspiration yielded thick purplish brown effusion from the knee joint and roentgenologically negative. Synovectomy through two seperate para-patellar incision were carried out, and no recurrence of symptom was demonstrable in 2 years post-operative follow-up. A brief summary of literatures is Submitted.

Sea urchin granuloma is a rare skin disorder, considered to be allergic or foreign body reaction caused by stick of spines of sea urchin. However, detection of the spine in the granuloma is quite difficult. A 27 year-old marine was seen with several asymptomatic hard nodules on the dorsum of hands, fingers, forearrns and knees at the injured site of the spines after a latent period of 6 rnonths. Histolagical examination revealed dermal granulomatous inflamation with hyperkeratotic and acanthotic epidermis. On examination with polarized microscopy, sea urchin spines in the granuloma were seen as bright white fragments in the dark field. Those nodules were regressed with intralesional injection of triamcinoIone.

PURPOSE: The purpose of this study was to explore the relationships of critical thinking disposition (CT), nursing work environment (NWE), and clinical decision making ability among nurses. METHODS: A cross-sectional, descriptive study design was conducted on 192 nurses who had worked for more than six months in five general hospitals. A self-reported questionnaire was used to collect data, which included demographics, CT, NWE, and clinical decision making ability. RESULTS: The mean score of CT was 3.5. The highest score was on the objectivity of CT and the lowest on systematicity. The mean score of NWE was 2.3. The highest score was on the collegial nurse-physician relations of NWE and the lowest on the staffing and resource adequacy. The mean score of clinical decision making ability was 3.3. In hierarchical multiple regression, affecting factors on clinical decision making ability were CT and NWE. CONCLUSION: The findings showed that clinical decision making ability is associated with CT and NWE. To improve clinical decision making ability, it is important to improve CT. In addition, it should be considered to improve NWE where the nurses can make a decision with their job through critical thinking.

BACKGROUND: Computerized topography(CT) is the method of choice for establishing patients with abdominal and/or pelvic trauma. However, the sensitivity of CT far detecting bladder rupture has been questioned. We investigated the roles of CT as the initial evaluation of abdominal and pelvic trauma in diagnosis of bladder rupture. METHODS: We reviewed the medical records and radiographs of 53 patients with bladder rupture for last 5 year. And among them, all radiographs of 30 patients who underwent both CT and retrograde cystography were evaluated independently by two urologists who had no knowledge of the patients' final diagnosis. RESULTS: Among 30 patients, all of patients were correctly diagnosed by retrograde cystography, but the CT diagnosis was correct in only 23 patients(76.7%), who were 17 patients(85.0%) with intraperitoneal rupture and 6 patients(60%) with extraperitoneal rupture. And of the 7 patients who were negative by the CT, all showed the sign of inadequate bladder distension. CONCLUSION: We suggest that CT, if properly performed with adequate bladder filling, is as sensitive for detection of bladder injuries as conventional cystography. Especially, in trauma patients with hematuria and suspected other organ injury, CT-cystography with retrograde filing may be as accurate as conventional cystography and obviate the need for an additional plain film cystography,

Multiple factors including gastroesophageal reflux disease (GERD) were evaluated for a case-control study in Chonnam area to investigate the causative entity of COPD. Data on the multiple causative factors from hospital records and interview survey were analyzed in three groups of COPD(64 cases as case group), normal lung (83 cases as control group 1) and non-COPD lung disease (45 cases as control group 2). Smoking status, history of adulthood pulmonary infection and frequent history of URI, socioeconomic status, and GERD were significantly different between COPD group and control group 1. Drinking status, physical height of the subjects and GERD were significantly different between COPD group and control group 2. If control group 1 was used, odds ratio of GERD and COPD was 5.68(95%confidence interval, 95% CI:2.59-12.45) and 4.81 (95% CI:1.89-10.53) when adjusted by age and smoking status. If control group 2 was used. Odds ratio of GERD and COPD was 4.22 (95% CI:1.69-10.56) and 4.59 (95% CI:1.64-12.86) when adjusted by alcohol and adulthood respiratory infection status. In summary, there results suggested that GERD might play a causative role in the development of COPD.
