Intra-articular hyaluronic acid injections for symptomatic treatment of osteoarthritis are widely used but can result in complications, such as infectious arthritis. Staphylococcus lugdunensis is a common normal skin flora but can cause severe infectious disease, such as infective endocarditis. We present the first report of infectious arthritis caused by methicillin-sensitive S. lugdunensis after intra-articular hyaluronic acid injection in an immunocompromised patient in Korea.

BACKGROUND: This study was designed to determine the relationship of propranolol pharmacokinetic parameters with portosystemic shunt in CCl4-induced cirrhotic rats. METHODS: Cirrhotic rats(n=6) were induced by intramuscular injection of CCl4 in olive oil(two time per weeks) for 12 weeks. Controls (n=6) were injected intramuscularly with the same dose of olive oil for 12 weeks. We evaluated the amount of portosystemic shunt by thallium-201 per rectal scintigraphy. After intravenous bolus injection of propranolol (2mg/kg) to rats, the serum propranolol concentrations were analyzed by a HPLC-fluorimetric detector system. Pharmacokinetic parameters such as C0, AUC, t(1/2(beta)), and CLp were determined in each group. Then, a small amount of heptic tissue was obtained and subjected to determination of the hepatic collagen content by quantitating 4-hydroxyproline and were inspected by microscope after hematoxylin and eosin stain. RESULTS: In liver biopsy, liver fibrosis progressed in CCl4-induced cirrhotic rats. The serum concentrations of propranolol were significantly (p < 0.01) elevated in CCl4-induced cirrhotic rats. Mean amount of 4-hydroxyproline, mean H/L ratio, and mean AUC in CCl4-induced cirrhotic rats was significantly (p < 0.01) higher than that in control rats. There was a relationship between AUC, H/L ratio, and amount of 4-hydroxyproline. CONCLUSION: H/L ratio may help in the selection of drug dosage (especially blood flow dependent drug) in pre-clinical studies for chronic liver disease during the drug development process.

Aprotinin is a nonspecific serine protease inhibitor and antifibrinolytic agent. It has been used to control bleeding and reduce the amounts of transfusion during the perioperative period. There are few reports on adverse effects following aprotinin use. However, several reports have been recently published, suggesting an increased risk for renal events or deaths in patients given aprotinin. We report two cases of ARF associated with aprotinin. To reduce perioperative blood loss, aprotinin was administered to two patients who underwent obstetrical surgeries in which ARF subsequently developed. Renal biopsies displayed microthrombi within the arterioles and small arteries, causing infarctions and collapses of glomeruli. Although renal functions were not completely recovered, the two patients are now being followed up without dialysis

PURPOSE: We wished to compare the ability of ultrasonography and radiography performed on the same day to detect rib fractures in minor chest injuries. MATERIALS AND METHODS: Two hundred and fifteen patients with minor chest injuries were selected. Radiography and ultrasonography were performed on the same day with these patients. Chest wall pain was the only presenting symptom. Two radiologists performed ultrasonography. Fractures were identified by a disruption of the anterior margin of the rib and costal cartilage. The incidence and location of fractures and complications revealed by radiography and ultrasonography were compared. RESULTS: Radiographs revealed the presence of 70 rib fractures in 50 (23%) of 215 patients and ultrasonography revealed the presence of 203 rib fractures in 133 (62%) of 215 patients. Ultrasonography uniquely identified 133 rib fractures in 83 patients. Ultrasonography identified a 2.9 fold increase in the number of fractures in a 2.6 fold number of subjects as compared to radiography. Of the 203 sonographically detected fractures, 201 were located in the rib, one was located at the costochondral junction, and one in the costal cartilage. There were no complications seen by either radiography or ultrasonography. CONCLUSION: Ultrasonography reveals more fractures than those that may be overlooked on radiography for minor chest injuries.

PURPOSE: Recently, obesity with metabolic syndrome is considered as an important risk factor in the development and progression of chronic kidney disease (CKD). Glomerulomegaly and focal segmental glomerulosclerosis (FSGS) are found in the obese patients, suggesting that investigation of structural- functional relationship in the obesity-related glomerulopathy (ORG) is needed to prevent CKD. Thus, we report here clinical and pathologic characteristics of ORG and its association with other clinical variables. METHODS: Obesity was defined by body mass index >25 kg/m2 and ORG morphologically by FSGS and glomerulomegaly or glomerulomegaly alone. Clinicopathologic findings and glomerular sizes of ORG (14 cases) were compared with age-matched controls with thin basement membrane disease. Multiple variable analysis was performed between glomerular size and clinical variables. RESULTS: There was no nephrotic syndrome or pretibial pitting edema in all obese patients. Mean glomerular diameter was increased in obese patients compared to controls (240+/-21 micrometer vs 197+/-21 micrometer, p=0.001). Seven cases had lesions with FSGS with glomerulomegaly and seven cases glomerulomegaly alone. Mild tubular atrophy, interstitial fibrosis and arteriolosclerosis were observed in more than half of patients. In obese patients, seven patients with FSGS had more elevated systolic blood pressure and tubular interstitial fibrosis compared to patients with glomerulomegaly only. Patients' systolic blood pressure and waist circumference were independent risk factors influencing the glomerular size in obese patients. CONCLUSION: FSGS or glomerulomegaly are prominent even in the mild obesity with insignificant clinical symptoms. This indicates that the clinical attention to glomerular disease is needed in obese patients.

BACKGROUND: Recent guidelines recommend that all cirrhotics undergo screening upper endoscopy to identifly risk patients for bleeding from varices. The aim of this study was to determine whether clinical and laboratory variables were predictive of the occurrence and progression of esophageal varices. METHODS: This is a retrospective analysis of cirrhotics who had a screening upper endoscopy during 10 years after liver biopsy. Fifty-eight patients were recruited. Univariate/multivariate analysis was used to evaluate associations between the development and progression of esophageal varices and patients characteristics including platelet count, liver chemistry value, prothrombin time, shunt index(heart to liver uptake ratio) through transrectal TI-201 liver scan, probability(P)-value (Y=3.3431-0.8160 x ALT/AST ratio-0.0343 x prothrombin time+2.6963 x shunt index, P=e(y)/(e(y)+1)), ascites, splenomegaly, hepatic encephalopathy. RESULTS: There were 36 patients without esophageal varices or with stable varices during 10 years and 22 patients with new developed esophageal varices or progressive varices during 10 years as determined by upper endoscopy. On multivariate analysis, patients with a probability(P)-value of > or = 0.647 and a platelet count of < or = 100,500/mm3 had a risk of the development and progression of esophageal varices. CONCLUSIONS: Non-endoscopic predictors (probability(P)-value and platelet count) could be used to stratify patients with cirrhosis for the risk of the development and progression of esophageal varices and such stratification could be used to improve the effectiveness of screening upper endoscopy for esophageal varices.

Bordetella bronchiseptica is a common cause of respiratory disease in animals but is a rare cause of human infection. Furthermore, most patients with Bordetella bronchiseptica infections are immunocompromised. The Bordetella bronchiseptica organism can cause pneumonia, septicemia, and peritonitis in humans with impaired immune systems. Additionally, it can lead to a life-threatening infection patients who have an underlying debilitation or impaired immunity. The respiratory tract is the most common site of infection. Sixty-two human cases of Bordetella bronchiseptica have been published in the English literature, and 84 % hadof the cases were associated with pneumonia or bronchitis. However, only one case of Bordetella bronchiseptica has been reported in South Korea, and it was associated with peritonitis. In the current study, we report a case of Bordetella bronchiseptica pneumonia diagnosed in an immunocompromised patient.

PURPOSE:In many countries, patients and dialysis unit physicians attempt to address issues regarding withholding and withdrawing dialysis through advance directives and clinical guidelines for dialysis utilization. However, there are only a few reports of withholding and withdrawing dialysis in Korea. This study was developed to investigate the attitudes of dialysis unit physicians regarding withholding and withdrawing dialysis in Korea. METHODS:A questionnaire survey was conducted among 45 dialysis unit physicians from January, 2006 to January, 2008. Physicians were asked about their decision making process to withhold and withdraw dialysis, and their opinions regarding the necessities of advance directives and guidelines for withholding and withdrawing dialysis. RESULTS:Analysis of surveys revealed that physicians agreed more about whether to withhold and withdraw dialysis in vegetative patients compared to patients with dementia ( p<0.001, p<0.001). There were more agreements about whether to withhold dialysis than whether to withdraw dialysis in patients with unimpaired cognition ( p<0.037). However, there were no differences in agreements between withholding and withdrawing dialysis in patients with severe neurological impairments. There appeared to be a general consensus regarding the need for guidelines addressing withholding and withdrawing dialysis (84.4%). However, opinions supporting the necessity for advance directives were not strongly favored (33.3%). CONCLUSION:Conflicting opinions are present among dialysis unit physicians regarding whether to withhold and withdraw dialysis according to a patient's neurological impairments. However, most dialysis unit physicians were of one accord regarding the need of guidelines for withholding and withdrawing dialysis.
