PURPOSE: This study was designed to evaluate the accuracy of ultrasound in detecting and estimating the size of pneumothorax METHODS: This was a prospective study with convenience sampling, based on researcher availability. Inclusion criteria were chest pain, sudden dyspnea, and chest trauma. Bedside ultrasound examination was performed to determine the presence of "lung sliding" and "comet tail" artifacts in order to rule out pneumothorax and the location of "lung point" when pneumothorax was detected. RESULTS: There were 97 patients enrolled; The cause of pneumothorax was spontaneous in 64 cases and traumatic in 33 cases. The Pearson correlation coefficient between ultrasound estimates and pneumothorax size by Collins method on erect chest X-ray was 0.874 (p<0.000), and the coefficient between ultrasound estimates and pneumothorax size on computed tomography was 0.820 (p<0.000). CONCLUSION: Ultrasound is more sensitive and specific than supine chest X-ray and even erect chest PA for the diagnosis of pneumothorax. Ultrasound allowed skilled physicians to approximate the size of pneumothorax accurately with good correlation with results obtained by both computed tomography and erect chest X-ray.

PURPOSE: In 2000, the American Heart Association and International Liaison Committee on Resuscitation published guidelines for CPR (Cardiopulmonary Resuscitation), and these guidelines were revised in 2005. Many physicians perform CPR differently than suggested by these guidelines. We investigated guideline conformation rates for CPR by non-emergency physicians. METHODS: From January 1st, 2005, to December 31st, 2005, and from January 1st, 2007, to September 30th, 2007, 103 in-hospital CPR cases were enrolled. We separated the 103 cases into two groups: 2005 patients and 2007 patients. Fifty-two cases in the 2005 group and 51 cases in the 2007 group were enrolled. The defibrillation method, defibrillation energy, epinephrine use, and atropine use were analyzed. RESULTS: Nineteen cases (82.6%) in the 2005 group and three cases (21.4%) in the 2007 group were performed using the appropriate defibrillation method (p=0.0002). Seventeen cases (73.9%) in the 2005 group and four cases (28.6%) in the 2007 group received the appropriate defibrillation energy (p=0.0069). Seven cases (14.0%) in the 2005 group and 16 cases (32.0%) in the 2007 group used the appropriate epinephrine dose (p=0.0325). Fourteen cases (28.0%) in the 2005 patient group and 14 cases (29.2%) inthe 2007 patient group used the appropriate atropine dose (p=0.8983). CONCLUSION: Although CPR guidelines were renewed in 2005, many physicians do not follow these guidelines. We suggest that adequate information, education, feedback, and further study are needed for guideline conformation.

BACKGROUND AND OBJECTIVES: A correlation between the BNP reduction ratio and prognosis could be expected to be found by evaluating the BNP reduction depending on the volume status during the early period. SUBJECTS AND METHODS: Between October 2002 and June 2004, 120 patients with acute heart failure (AHF)(<1 month) were included. The patients were divided into three groups according to their volume status, as follows. Group I: patients with clinical & radiological wet status, Group II: clinical dry & radiological wet status and Group III: clinical & radiological dry status. The blood BNP (Triage(r)) level and clinical parameters were analyzed. The bad prognostic parameters were defined as readmission due to heart failure, a major adverse cardiac event or cardiovascular death. RESULTS: The mean patient age was 68.0+/-12.7 years, and 50.0% of the subjects were male. The most frequent etiology of AHF was ischemic heart disease (35.8%). There were 61.7, 24.1 and 14.2% in Groups I, III and III, respectively. The baseline BNP level was higher in group I and II than in group III patients (I: 1540.4+/-1202.8, II: 1482.8+/-1281.6, III: 666.4+/-827.9 pg/mL, p=0.036) as was the early BNP reduction ratio (I: 69.8+/-27.1, II: 67.4+/-32.8, III: 1.3+/-144.9%, p=0.007). Sixteen (13.3%) patients had a poor prognosis. From a logistical analysis, the early BNP reduction ratio (p=0.004) and creatinine level (p=0.029) were significant predictors of the clinical outcomes. CONCLUSION: The early change in the BNP level varied depending on the degree of congestive status, and was also correlated with the level of clinical outcomes. Therefore, in our opinion, the early monitoring of the BNP level will provide significant clinical information in AHF patients.

Gout occurs as a response to monosodium urate crystal, that is present in joints, bones and soft tissue. The classic symptoms of gouty arthritis are recurrent attacks of acute, markedly painful monoarticular or oligoarticular inflammation; but polyarthritis and chronic arthritis can also occur. Differential diagnosis from infectious arthritis is important. A definitive diagnosis requires the direct identification of urate crystals in the joint, and the exclusion of infection. We report the case of systemic inflammatory response syndrome (SIRS), developed from acute polyarticular gout. SIRS is characterized by loss of local control of inflammation, or an overly activated response resulting in an exaggerated systemic response. The SIRS was presumably due to systemic effects of a localized inflammatory response to urate crystals.
