Cogan's syndrome can accompany a variety of systemic vasculitides including aortitis. A 45-year-old woman with a history of typical Cogan's syndrome presented with orthopnea and exertional dyspnea. Echocardiography demonstrated severe aortic valve insufficiency. Computed tomographic angiography demonstrated active vasculitis affecting the ascending and descending aortas and also showed stenosis of the left subclavian artery, both renal arteries, the celiac axis, the superior mesenteric artery, and the right common iliac artery. She received high dose corticosteroid and then underwent an aortic valve replacement. This is the first case of Cogan's syndrome with aortitis in Korea.

A paragonimiasis infestation is caused by the paragonimus species. Paragonimiasis mainly occurs by ingestion of raw or undercooked freshwater crabs or crayfish. In our country, the prevalence of paragonimiasis was high until late 1960s due to eating habits, but after the 1970s the prevalence of the disease has markedly decreased and now the disease is rarely seen. The diagnosis of tuberculosis by Chest X-ray is often confused with pulmonary carcinoma, bacillary and parasitic infections, and chronic mycosis. Pulmonary paragonimiasis must be considered in the differential diagnosis of lung cancer especially in the appropriate clinical setting because effective treatment with praziquantel can be rewarding. We report a case of a 58-year-old woman with pulmonary paragonimiasis that was suspicious for lung cancer, as detected by biopsy.

Eosinophilic myositis is a rare idiopathic inflammatory muscle disease, and the patients with this malady present with diverse signs and symptoms such as muscle swelling, tenderness, pain, weakness, cutaneous lesions and eosinophilia. The etiology and pathogenesis of eosinophilic myositis remain elusive. Several drugs may occasionally initiate an immune mediated inflammatory myopathy, including eosinophilic myositis. We report here on a case a 17-year-old female patient who had taken anti-tuberculosis medicine for tuberculosis pleurisy. She presented with many clinical manifestations, including fever, skin rash, proximal muscle weakness, dyspnea, dysphagia and hypereosinophilia. She was diagnosed with eosinophilic myositis by the pathologic study. The muscle weakness progressed despite of stopping the anti-tuberculosis medicine, but the myositis promptly improved following the administration of glucocorticoid. Although drug induced myopathies may be uncommon, if a patient presents with muscular symptoms, then physicians have to consider the possibility of drug induced myopathies.

Dendritic cells (DCs) play a key role in activating the immune response against invading pathogens as well as dying cells or tumors. Although the immune response can be initiated by the phagocytic activity by DCs, the molecular mechanism involved in this process has not been fully investigated. Trp-Lys-Tyr-Met-Val-Met-NH2 (WKYMVM) stimulates the activation of phospholipase D (PLD) via Ca2+ increase and protein kinase C activation in mouse DC cell line, DC2.4. WKYMVM stimulates the phagocytic activity, which is inhibited in the presence of N-butanol but not t-butanol in DC2.4 cells. Furthermore, the addition of phosphatidic acid, an enzymatic product of PLD activity, enhanced the phagocytic activity in DC2.4 cells. Since at least two of formyl peptide receptor (FPR) family (FPR1 and FPR2) are expressed in DC2.4 as well as in mouse bone marrow-derived dendritic cells, this study suggests that the activation of FPR family by WKYMVM stimulates the PLD activity resulting in phagocytic activity in DC2.4 cells.

Human toxocariasis is a zoonotic parasitic disease caused by Toxocara canis or Toxocara cati larvae. Human infection is usually an outcome of accidental ingestion of the embryonated eggs, and the involvement of central nervous system is rare. We report a case of cerebral infarction which was caused by toxocariasis in adult, who had headache, abdominal pain and right side weakness. He had only a history of ingestion of raw liver of deer.

Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university hospitals in Korea. Total 1,605 blood isolates were collected from 2006 to 2007, and 1,144 isolates were considered true pathogens. HA-BSI accounted for 48.8%, CA-BSI for 33.2%, and HCA-BSI for 18.0%. HA-BSI and HCA-BSI were more likely to have severe comorbidities. Escherichia coli was the most common isolate in CA-BSI (47.1%) and HCA-BSI (27.2%). In contrast, Staphylococcus aureus (15.2%), coagulase-negative Staphylococcus (15.1%) were the common isolates in HA-BSI. The rate of appropriate empiric antimicrobial therapy was the highest in CA-BSI (89.0%) followed by HCA-BSI (76.4%), and HA-BSI (75.0%). The 30-day mortality rate was the highest in HA-BSI (23.0%) followed by HCA-BSI (18.4%), and CA-BSI (10.2%). High Pitt score and inappropriate empirical antibiotic therapy were the independent risk factors for mortality by multivariate analysis. In conclusion, the present data suggest that clinical features, outcome, and microbiologic features of causative pathogens vary by origin of BSI. Especially, HCA-BSI shows unique clinical characteristics, which should be considered a distinct category for more appropriate antibiotic treatment.

PURPOSE: Vascular calcification (VC) scores on simple plain radiographic films are known to be associated with coronary artery disease (CAD) in hemodialysis (HD) patients. However, there is no report comparing VC scores on plain radiographic films according to dialysis modality. We hypothesized that there are some differences of VC scores on plain radiographs for the assessment of CAD according to dialysis modality. METHODS: We recruited 78 peritoneal dialysis (PD) patients and compared to 61 HD patients. We defined significant VC as any one finding among the abdominal aortic calcification (AAC) score > or =5, VC score of the hands and pelvis > or =3, or medial artery calcification of the feet on plain radiographs. RESULTS: The prevalence of CAD and significant VC were not different according to dialysis modality. Every VC score on the plain radiographs was highly correlated with each other, but VC evaluation on plain radiographs by single method overlooked nearly 30% of other significant VC sites in PD and HD patients. AAC score was most useful method for the prediction of CAD as a single VC scoring method. There was no association between VC of the feet and CAD in PD patients. Lower high density lipoprotein cholesterol was associated with significant VC on plain radiograph in PD patients. CONCLUSION: Significant VC formation on plain radiographs was not different according to dialysis modality. It is helpful to check several plain radiographs for the decision of CAD evaluation and not overlooking significant VC in both HD and PD patients.

BACKGROUND: Chronic kidney disease is a common complication after liver transplantation. In this study, we analyzed the results of kidney biopsy in liver transplantation recipients with renal impairment. METHODS: Between 1999 and 2012, 544 liver transplants were performed at our hospital. We retrospectively analyzed the clinical and histological data of 10 liver transplantation recipients referred for kidney biopsy. RESULTS: The biopsies were performed at a median of 24.5 months (range, 3-73 months) after liver transplantation. The serum creatinine level was 1.81+/-0.5mg/dL at the time of kidney biopsy. There were no immediate complications. The most common diagnosis was glomerulonephritis (GN), such as immunoglobulin A nephropathy (n=4), mesangial proliferative GN(n=1), focal proliferative GN (n=1), and membranous GN (n=1). Typical calcineurin inhibitor (CNI)-induced nephrotoxicity was detected in three cases (30%).Chronic tissue changes such as glomerulosclerosis, interstitial fibrosis, and tubular atrophy were present in 90%, 80%,and 80% of cases, respectively, and mesangial proliferation was detected in 40%of cases. We began treatment for renal impairment based on the result of kidney biopsy; for example, angiotensin-receptor blockers or steroids were prescribed for GN, and the CNI dose was reduced for CNI nephrotoxicity. As a result, eight of 10 patients showed improvement in glomerular filtration rate, but two progressed to end-stage renal disease. CONCLUSION: Kidney biopsy is a safe and effective method for determining the cause of renal impairment after liver transplantation. Management of patients based on the result of kidney biopsy may improve renal outcomes.

Purpose:
Quality of life (QOL) has become important in the trend of emphasizing patient satisfaction. This study aimed to evaluate the QOL in patients who underwent laparoscopic or robotic gastrectomy for gastric cancer.
Methods:
A prospective trial was performed involving patients who underwent laparoscopic or robotic gastrectomy for primary gastric cancer at 11 hospitals in Korea. Within this comparative trial, QOL, postoperative pain, and long-term complications were exanimated. The quality-of-life questionnaire (QLQ)-C30 and QLQ-STO22 developed by the European Organization for Research and Treatment of Cancer were used for the QOL survey. We compared the data after dividing it into several types of characteristics as follows; device (robotic or laparoscopic), operation type, pathological stage, and sex.Biased components were extracted by logistic regression analysis. Propensity score matching was applied to the data set with the biased components.
Results:
In total, 434 patients (211 for laparoscopic surgery and 223 for robotic surgery) were enrolled, out of which 321 patients who responded to both preoperative and postoperative surveys were selected for analysis. Robotic gastrectomy was not different from laparoscopic gastrectomy with respect to postoperative QOL. Distal gastrectomy showed better scores than total gastrectomy in terms of role functioning, social functioning, fatigue, nausea/vomiting, pain, dyspnea, constipation, financial difficulties, dysphagia, eating restrictions, anxiety, taste, and body image. Male patients showed better scores on the 19 scales compared to female patients.
Conclusion
Robotic and laparoscopic approaches for gastric cancer surgery did not differ from each other with respect to QOL. Distal gastrectomy resulted in better QOL than total gastrectomy.

Cardioprotective effect of fimasartan, a new angiotensin receptor blocker (ARB), was evaluated in a porcine model of acute myocardial infarction (MI). Fifty swine were randomized to group 1 (sham, n=10), group 2 (no angiotensin-converting enzyme inhibitor [ACEI] or ARB, n=10), group 3 (perindopril 2 mg daily, n=10), group 4 (valsartan 40 mg daily, n=10), or group 5 (fimasartan 30 mg daily, n=10). Acute MI was induced by occlusion of the left anterior descending artery for 50 min. Echocardiography, single photon emission computed tomography (SPECT), and F-18 fluorodeoxyglucose cardiac positron emission tomography (PET) were performed at baseline, 1 week, and 4 weeks. Iodine-123 meta-iodobenzylguanidine (MIBG) scan was done at 6 weeks for visualization of cardiac sympathetic activity. Left ventricular function and volumes at 4 weeks were similar between the 5 groups. No difference was observed in groups 2 to 5 in SPECT perfusion defect, matched and mismatched segments between SPECT and PET at 1 week and 4 weeks. MIBG scan showed similar uptake between the 5 groups. Pathologic analysis showed similar infarct size in groups 2 to 5. Infarct size reduction was not observed with use of fimasartan as well as other ACEI and ARB in a porcine model of acute MI.
