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.

Patients with massive pulmonary embolism may present with severe dyspnea at rest, syncope, or cardiac arrest. Early diagnosis and treatment are essential to reduce mortality; however, patient-specific factors can influence the hemodynamic effect of pulmonary embolism. Here, we present a case of massive pulmonary embolism masked by a ventricular septal defect in a 73-year-old female.

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: 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.

BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is a condition that often develops in young women and, consequently, physicians should frequently manage and monitor pregnant patients with this disorder. METHODS: We reviewed the charts of 30 women with chronic ITP delivered in 31 pregnancies from January 1995 to December 2003. RESULTS: Fifteen patients were diagnosed with ITP before pregnancy and sixteen patients were diagnosed during pregnancy. The mean platelet counts before pregnancy, during pregnancy, and at delivery were 70, 040/mm3, 83, 960/mm3, and 62, 680/mm3, respectively. The symptoms of hemostatic impairment were not noted in most of the pregnancies (77%, 24/31). During pregnancy and at delivery, most of the women (61%, 19/31) received various kinds of treatment to raise platelet counts. At delivery, the most commonly used therapy was platelet transfusion (48.4%, 15/31). Seven pregnancies (22.6%) were treated with corticosteroids during pregnancy and at delivery. Five pregnancies (16.1%) were treated with IV IgG during pregnancy and at delivery. Fifteen deliveries (51.7%) were performed by cesarean section and fourteen (48.3%) with vaginal delivery. Bleeding was uncommon at delivery. There were no cases of infants with any clinical signs of hemorrhage. CONCLUSION: Our current results suggest that ITP in pregnancy can proceed safely with low hemorrhagic risk in both infants and mothers, and that mothers with ITP can deliver healthy infants without serious hemorrhagic complications.

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

Sjögren's syndrome is a systemic autoimmune disease characterized by sicca symptoms and extraglandular manifestations. Anemia, leukopenia, thrombocytopenia and lymphoproliferative disorders are well-known extraglandular, hematological complications of Sjögren's syndrome. These hematologic alterations are usually mild and respond well with steroid therapy. We report a case of a 52-year-old female patient who was initially presented with thrombocytopenia. The patient was then diagnosed with primary Sjögren's syndrome and initially treated with steroid. The patient's platelet count was decreased when steroid was tapered. The dose of steroid could be effectively reduced after combined medication with hydroxychloroquine.

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.
