Primary community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) endocarditis has rarely been reported in healthy individuals without risk factors, such as skin and soft tissue infections, and intravenous drug abuse. We describe a case of infective endocarditis by CA-MRSA (ST72-PVL negative-SCCmec IVA) in previously healthy individuals with no underlying medical condition and CA-MRSA colonization in the family.

We report a case of vertebral osteomyelitis with epidural abscess caused by Streptococcus constellatus. The patient was present with fever, back pain, and dyspnea for 1 week. The patient was previously healthy and did not have any predisposing factor. After evaluation, the patient was diagnosed as Streptococcus constellatus vertebral osteomyelitis. He was successfully treated with surgical debridement and antibiotic therapy. To the best of our knowledge, this is the first case of S. constellatus vertebral osteomyeltis with epidural abscess to be reported in Korea.

Klebsiella pneumoniae is a pathogen that causes a wide range of infections in human, and has a tendency to metastasize to multiple organs. We report two rare cases of K. pneumoniae infection that have spread to multiple organs without being accompanied by liver abscess. A 59-year-old man (case 1) was admitted due to left knee pain. Microbiologic and radiologic studies revealed bacteremia, septic arthritis, pneumonia, prostatitis, and endophthalmitis caused by K. pneumoniae. A 48-year-old man (case 2) was admitted due to febrile sensation. Microbiologic and radiologic studies revealed bacteremia, pneumonia, urinary tract infection, endophthalmitis, and cerebritis caused by K. pneumoniae. With appropriate use of effective antibiotics and therapeutic measures, the patients recovered but with some sequelae.

Acute eosinophilic pneumonia(AEP) was first described in 1989 and represents a clinical entity distinct from chronic eosinophilic pneumonia. AEP is characterized by acute respiratory insufficiency, hypoxemia, fever, diffuse radiographic infiltrates, and eosinophilia in bronchoalveolar lavage fluid or lung biopsies in the absence of infection, atopy, or asthma. Rapid response to corticosteroids is characteristic. We experienced a 47-year-old metal driller presenting typical clinical and radiological characteristics of AEP. We confirmed eosinophilic pneumonia with brochoalveolar lavage analysis and transbronchial lung biopsy. We report a case of AEP diagnosed by clinical, radiographic, and histologic findings with a brief review of the literature.

The common arterial trunk is a congenital cardiovascular malformation in which one arterial trunk gives origin to the aortic arch, pulmonary and coronary arteries. Other cardiovascular malformations are often associated, such as ventricular septal defect, aortic arch interruption, patent arterial duct and so on. During the early period of life, the persistence of the increased pulmonary arteriolar resistance results in cyanosis. As the pulmonary vascular resistance decreases, the cyanosis disappears but signs of congestive heart failure become the main problems. We report five cases of common arterial trunk that was confirmed by autopsy at Chungnam National University Hospital, Seoul National University Hospital, and Yonsei University Severance Hospital between 1983 and 1995. The ages of these patients at autopsy were 8-28 days and four of them were male. Pulmonary arteries arose as a pulmonary trunk in two cases but three cases showed two arteries arising separately from the posterior wall of the common trunk. The type of ventricular septal defect was juxtatruncal in every case. All five cases had three leaflet truncal valves but three cases showed dysplasia of the leaflets. Interruption of aortic arch was associated in two cases. The cause of death was renal failure in two cases, cardiac failure after corrective surgery in two cases, and pulmonary edema and failure in one case.

PURPOSE: This study was performed to evaluate the aluminum level in hemodialysis patients and to find a correlation between aluminum level and bone specific alkaline phosphatase level. METHODS: Eighty five randomly selected patients with end-stage renal disease, undergoing maintenance hemodialysis treatment over 1 year were studied. Serum aluminum and bone specific alkaline phosphatase concentration were measured. Low dose desferrioxamine test (5 mg/kg) was done. RESULTS: The serum aluminum concentration before and after low dose desferrioxamine test were 4.21+/-2.13 microgram/L and 8.89+/-4.48 microgram/L (p<0.01) respectively. Bone-specific alkaline phosphates and parathyroid hormone concentration were 39.08+/-39.90 mg/dL and 98.27+/-112.92 pg/mL. The aluminum level after desferrioxamine test was correlated with duration of hemodialysis (r=0.238, p=0.03). Aluminum level was not correlated with bone specific alkaline phosphatase level. CONCLUSION: Aluminum level was lower than that of previous studies. Aluminum level was not increased in patients with low bone specific alkaline phosphatase. Thus, it seems that serum aluminum level is not a major problem in hemodialysis patients with lower turnover bone disease. However, confirm diagnosis of aluminum related bone disease in hemodialysis patients needs combined study of bone histology with a large number of cases.

Cardiac contusion is an increasingly recognized entity in patients with nonpenetrating chest injury. Unifortunately, the diagnosis of cardiac trauma, particularly cardiac contusion, is imprecise and may be confounded by the presence of associated injuries, hypoxia, shock, and metabolic abnormalities. Symptomatic cardiac injury follwing blunt chest trauma is relatively rare, and valvular injury is even rarer. The valves most commonly affected are mitral and tricuspid. Although tricuspid regurgitations are usually asymptomatic and can resolve spontaneously, recent developments in echocardiography made possible the precise diagnosis of valvular injuries noninvasively, The authors report the case of tricuspid regurgitation incidentally detected by echocardiography in a construction worker who had suffered multiple fractures.

PURPOSE: A tracheostomy is an important, life-saving procedure to maintain a patent airway. Our aim was to evaluate the effects and safety of tracheostomies done by emergency physicians. METHODS: This was a retrospective study conducted in the emergency intensive care unit (ICU) of a regional emergency medical center. We enrolled consecutive patients who had a tracheostomy in the emergency ICU between November 2004 and September 2008. We collected data on demographic characteristics, diagnosis at admission, the indication for a tracheostomy, time from intubation to tracheostomy, weaning success, time from tracheostomy to weaning, hospital stay, survival discharge, and complications. We divided the patients into two groups: the EM group included patients who had a tracheostomy done by an emergency physician; the OL group had it done by an otolaryngologists. We then made between-groups comparisons. RESULTS: One hundred forty six patients were enrolled in this study. Of the 146 patients, 94 were included in the EM group and 52 in the OL group. There was no significant difference in the demographic characteristics except age, diagnosis at admission, indication of tracheostomy, time from intubation to tracheostomy, weaning success, time from tracheostomy to weaning, hospital stay, and survival discharge between the two groups. There was no significant difference in demographic characteristics? or in the incidence of complications between the two groups. CONCLUSION: Tracheostomy done by emergency physicians are as effective and safe as ones done by otolaryngologists.
