OBJECTIVES: Septic shock is characterized by the circulatory failure including vasodilation, hyporeactivity to vasoconstrictor agents and organ ischemia in association with multiple organ failure and increased platelet aggregation and blood coagulation. In the present study, we investigated the preventive effects of N-nitro-L-arginine methyl ester (L-NAME, 30mg/kg, i.p.), a non-selective nitric oxide synthase (NOS) inhibitor, S-methylisothiourea sulfate (SMT, 5mg/kg, i.p.) and pentoxifylline (PTX,10mg/kg, i.p.) on the multiple organ dysfunction in a rat model of circulatory shock induced by bacterial endotoxin (E. coli lipopolysaccharide: LPS) and discussed the mechanism underlying the development of multiple organ failure. METHODS: The effect of each other N-nitro-L-arginine methyl ester(L-NAME, 30 mg/kg, i.p.), a non-selective nitric oxide synthase(NOS) inhibitor, S-methyli-sothiourea sulfate(SMT, 5mg/kg, i.p.) and pentoxifylline (PTX, 10mg/kg, i.p.) were comparatively evaluated following inducing circulatory shock by means of infusion of bacterial endotoxin to the rat model. RESULTS: 1) The systemic mean arterial blood pressure decreased by 48.7mmHg and vascular hyporeactivity to noradrenaline injection(1 g/kg, i.v.) upon intravenous administration of LPS. 2) Endotoxemia for 6hours resulted in little change in the numbers of white blood cells and neutrophils but a significant reduction in the numbers of platelets. The variables were not affected by the inhibitors. 3) Endotoxemia for 6hours caused a significant increase in serum nitric oxide level (P<0.01) which was inhibited by SMT, but not by L-NAME and PTX. 4) Upon injection of LPS, serum creatinine(0.65+/-0.08mg/dl) and urea(28.7+/-5.9mg/dl) were significantly elevated to 0.92+/-0.12 (P<0.05) and 54.3+/-2.1mg/dl (P< 0.01). These elevated levels were significantly attenuated by PTX but not by L-NAME and SMT. 5) Endotoxemia for 6 hours resulted in a significant increases in serum ALT(988.8+/-28.2 IU/L, P<0.01) and AST levels(1470.5+/-396.5 IU/L, P<0.01) from basal levels of ALT(67.8+/- 11.7IU/L) and AST(170.3+/-14.8IU/L). These increased activities were significantly attenuated by PTX, but not by L-NAME and SMT. The level of LDH(1279.8+/-156.2IU/L) was significantly increased by LPS treatment to 2932.0+/-519.9IU/L (P<0.05), which was inhibited by PTX. 6) Upon LPS treatment, the myeloperoxidase activity in the lung homogenate was significantly increased by LPS treatment (P<0.05), whereas that in the liver showed less change. The increased activity was reduced by PTX (P<0.05), but not by L-NAME and SMT. 7) The level of serum malondialdehyde, an index of lipid peroxidation by oxygen free radicals, was little influenced by LPS. CONCLUSION: Based on these results, it is summarized that PTX characteristically inhibited the development of multiple ogran dysfunction in a murine model of endotoxemia. Thus, it is concluded that the formation of TNF and increased activity of neutrophils may importantly contribute to the development of LPS-induced endotoxemia.

BACKGROUND: Some researchers have questioned the necessity of adjusting glomerular filtration rate (GFR) by body surface area (BSA). We compared the relationship between estimated GFR (eGFR) and radionuclide GFR (rGFR) with or without BSA adjustment by comparing the results obtained using various formulae with those obtained using 2 new proposed formulae. METHODS: A retrospective study was performed using 204 Korean individuals whose GFR had been estimated by the (99m)Tc-diethylenetriaminepentaacetic acid method between March 2004 and July 2008. We used the modification of diet in renal disease (MDRD) II formula, Mayo clinic quadratic (MCQ) formula, Cockcroft-Gault (CG) formula, and lean body mass-adjusted CG formula. Two new formulae, skeletal muscle mass index (SMI)-adjusted CG formula and SMIx3.4/SCr, were proposed by us. We analyzed each parameter with Pearson's correlation coefficient and also obtained the bias values. RESULTS: BSA did not satisfy the fundamental prerequisites of an adjustment factor for rGFR. MDRD II and MCQ GFR estimates demonstrated higher Pearson's correlation coefficient with BSA-unadjusted rGFR than they did with BSA-adjusted rGFR. The other GFR formulae estimates showed better correlation with rGFR and more favorable bias (P<0.001) when both GFR estimates and rGFR values were BSA-unadjusted. SMI-adjusted CG and SMIx3.4/SCr GFR estimates demonstrated correlation with rGFR and bias values similar to those of the MDRD II and CG GFR estimates. CONCLUSIONS: We suggest that absolute, non-corrected GFR and GFR estimate be preferred in daily practice. The absolute, non-corrected GFR and GFR estimate are considered helpful for patients with eGFR< or =60 mL/min/1.73 m2. We also recommend the clinical use of the new formulae, SMI-adjusted CG and SMIx3.4/SCr (BSA-unadjusted).

BACKGROUND: The polymerase chain reaction (PCR) test is important for the confirmatory diagnosis of tuberculosis (TB) caused by Mycobacterium tuberculosis. The aim of this study was to analyze the yield of repeated PCR testing in patients with confirmed pulmonary TB. METHODS: The medical records of 130 patients, who had more than two consecutive PCR tests and a M. tuberculosis-positive sputum culture from August, 2006 to December, 2007, were retrospectively reviewed for the purposes of this study. A positive TB-PCR test was defined as at least one positive test result. RESULTS: The cumulative positive PCR test rate was 80% (104/130), with gradually increasing rates of positive findings upon the first, second and third TB-PCR tests with 52.3%, 68.5% and 75.4%, respectively. However, further testing did not increase the positive rate further. CONCLUSION: Repeated PCR testing at least three times for M. tuberculosis is helpful for diagnosis of pulmonary TB.

There have been a few reports of hemophagocytic lymphohistiocytosis (HLH) with chromosomal abnormalities. Clonal chromosomal abnormalities in HLH patients are usually found in association with hematologic malignancies and rarely with epstein-barr virus (EBV) infection. Here, we report a fatal case of HLH with clonal karyotype abnormalities. A 75-yr-old man was admitted with persistent anorexia and high fever. Laboratory data revealed pancytopenia, hypofibrinogenemia, hyperferritinemia, prolonged prothrombin time and activated partial thromboplastin time, and marked elevated level of serum transaminases. In real time-PCR using whole blood, EBV DNA was not detected but cytomegalovirus (CMV) DNA was detected. The bone marrow aspiration smear showed hyperplasia of mature histiocytes with prominent hemophagocytosis. In chromosomal analysis of bone marrow aspirates, complex chromosomal abnormalities were found. In spite of steroid pulse therapy and antibiotic treatment, he died of disseminated intravascular coagulopathy.

Spontaneous hemothorax vary in cause and are rare for hemothorax induced osteochondroma. Sometimes hemothroax is reported due to osteochondroma induced injury of diaphragm, lung, pericardium, heart, or pleura. We report a patient with diaphragm laceration due to osteochondroma.

BACKGROUND: This study evaluates the bacterial pathogens of Ventilator-associated pneumonia (VAP) in a tertiary referral hospital. METHODS: A total of 109 bacterial pathogens from 91 adult patients with VAP, who were admitted to the medical intensive care unit from January 2008 to December 2009, were examined. Clinical characteristics, bacterial pathogens, and resistance profiles were analyzed. RESULTS: Staphylococcus aureus (44%) was the most frequently isolated. Acinetobacter baumanii (30%), Pseudomonas aeruginosa (12%), Stenotrophomonas maltophilia (7%), Klebsiella pneumoniae (6%), and Serratia marcescens (2%) were isolated from the transtracheal aspirates or bronchoalveolar lavage in patients with VAP. There was no significant difference of bacterial pathogens between early and late onset VAP. All isolated S. aureus were methicillin resistant S. aureus; the imipenem resistance rate of A. baumanii was 69%. CONCLUSION: The two most frequent pathogens of VAP were S. aureus and A. baumanii. There were no pathogenic differences between early and late onset VAP.
