Glomerulonephritis (GN) is sometimes associated with infective endocarditis (IE). Bartonella endocarditis is difficult to diagnose because it is rare and cannot be detected by blood culture. This is the first report of cytoplasmic anti-neutrophil cytoplasmic antibody-positive subacute endocarditis-associated GN caused by Bartonella infection in South Korea. A 67-year-old man was hospitalized due to azotemia. He complained of weight loss and anorexia for 6 months. A diagnosis of IE was made based upon echocardiographic detection of vegetations on the mitral and aortic valves and a Bartonella antibody titer of 1:2,048. Renal histology identified focal crescentic GN. Azotemia and proteinuria improved after doxycycline and rifampin treatment combining with steroid therapy.

The concomitant presence of posterior mitral annular calcification and infectious mitral valve lesions poses a technical challenge with considerable perioperative risk when using previously proposed techniques for mitral valve surgery. Herein, we report a case of the use of a modified surgical technique to successfully treat a patient with mitral infective endocarditis complicated by a subendocardial abscess and extensive posterior mitral annular calcification.

Purpose: We report a case of pyogenic arthritis of the shoulder secondary to infective endocarditis. Materials and Methods: A 70 year-old male who had suffered from pyogenic arthritis of the left shoulder secondary to infective endocarditis was treated with artificial valvuloplasty, arthroscopic synovectomy and drainage. Results: Infection was cured and the patient achieved a good functional outcome. Conclusion: Pyogenic arthritis of the shoulder is rarely associated with infective endocarditis. However, if the symptoms are misdiagnosed as musculoskeletal symptoms associated with infective endocarditis, serious complications may arise. As such, musculoskeletal symptoms associated with infective endocarditis should be paid careful attention.

Object : To determine whether to use surgical or medical therapy in treatment of infectious intracranial aneurysms, we reviewed two recent cases of infectious intracranial aneurysms and others known previous reports of aforementioned cases. Hence, we attempted to compare the validity and effectiveness of surgical and medical treatment. Method : Recently, we treated two cases of ruptured infectious intracranial aneurysms. In former case, the aneurysm was located distal to the middle cerebral artery in a patient with mild mitral regurgitation of the heart. In latter case, the aneurysm was multiple with varying hemorrhage. The hemorrhage was located bilaterally and a moderate mitral regurgitation and infective endocarditis were accompanied in this patient. Result : Due to the large size of the intracranial hematoma, stable medical condition, and easy resectability, we treated the former patient surgically. And, because of successive hemorrhage by multiple aneurysmal rupture, and the risk of heart failure, we treated the latter patient medically with serial follow-up angiography. Both patients are at present in good health. Conclusion : Because of the variability in associated factors, such as the patient's health, the number of lesions, location, anatomy of the aneurysms and the causative organism, each patient's care must be individualized and tailored to the patient's particular clinical situation.

Prosthetic valves are being widely used in the treatment of heart valve disease. Prosthetic valve endocarditis (PVE) is one of the most catastrophic complications seen in these patients. In particular, prosthetic valve dehiscence can lead to acute decompensation, pulmonary edema, and cardiogenic shock. Here, we discuss the medical management of late PVE in a patient with a prior history of late and redo early PVE and recurrent dehiscence. According to the present case, we can summarize the learning points as follows. A prior history of infective endocarditis increases the risk of relapse or recurrence, and these patients should be evaluated very cautiously to prevent late complications. Adequate debridement of infected material is of paramount importance to prevent relapse. A history of dehiscence is associated with increased risk of relapse and recurrent dehiscence.

Between January 1986 and June 1994, 23 patients underwent surgical intervention for infective endocarditis at Wonkwang University Hospital. There were 13 male and 5 female, ran ing in age from 13 to 67(mean 43.7 $\pm$ 5.8) years. 21 had native valve endocarditis and 2 had prosthetic valve endocardits. The most common causative organism was streptococci in 9 patients, and the others were staphylococci in 7 patients and unknown in 7 patients. The infection was in the mitral valve in 10 patients, the aortic valve in 6 patients, the aortic and mitral In 5 patients, 2 in tricuspid. Surgical indications for surgery were intractable congestive heart failure, giant growing vegetation and severe valvular insufficiency. There were 3 perioperative death (13%) and no late death. The main causes of death were cerebral embolism in 2 due to recurrent endocarditis and low cardiac output in 1. By NYHA functional classification, all patients were in class III or IV preoperatively, and all patients were improved postoperatively with HYHA functional classification in class I or II. In conclussion, early operative intervention is life-salving in patients with persistent or progres ive congestive heart failure, irrespective of the activity of the infectious process or the duration of antibiotic therapy.

A 12-year-old castrated male miniature Schnauzer had anorexia, vomiting, lethargy, and fever for four days. The dog had leukocytosis, thrombocytopenia, hypoglycemia, hypoalbuminemia, hyperbilirubinemia, increased hepatic enzymes on hematologic and biochemical examinations. On abdominal ultrasonographs, there was an enlarged gallbladder with hyperechoic irregular wall thickening. Echocardiography showed vegetative change and regurgitation of aortic and mitral valves. E.coli was identified through ultrasound guided percutaneous cholecystocentesis and bile culture. Bacterial cholecystitis and concurrent endocarditis were diagnosed. The dog was recovered from sepsis with antibacterial and aggressive supportive therapy.

Patient with congenital heart disease are susceptible to infective endocarditis, and bacteremia following dental procedures may lead to infective endocarditis is these patients. Therefore prophylactic antibiotics are recommended for patients with congenital heart disease who are undergoing dental procedures that are associated with infective endocarditis. In 1997 American Heart Association revised guidelines for a prophylaxis against infective endocarditis. The new American Heart Association recommendations for the prevention of infective endocarditis represent a substantial departure from past guidelines. Major change involve the indications for prophylaxis, antibiotic choice and dosing that may reduce bacteremic risk. Previously, antibiotic prophylaxis was suggested for dental procedures associated with any amount of bleeding. Now only those that are associated with significant bleeding are recommended for prophylaxis as dictated by clinical judgement. Recommended antibiotic prophylaxis regimens now consist of a single preprocedural dose, no second dose is recommended. This report presents three cases of dental treatment of patients with congenital heart disease under the most recent American Heart Association recommendations for antibiotic prophylaxis.

Biomarkers are playing an increasingly important role in antimicrobial stewardship. Their applications have included use in algorithms that evaluate suspected bacterial infections or provide guidance on when to start or stop antibiotic therapy, or when therapy should be repeated over a short period (6-12 h). Diseases in which biomarkers are used as complementary tools to determine the initiation of antibiotics include sepsis, lower respiratory tract infection (LRTI), COVID-19, acute heart failure, infectious endocarditis, acute coronary syndrome, and acute pancreatitis. In addition, cut-off values of biomarkers have been used to inform the decision to discontinue antibiotics for diseases such as sepsis, LRTI, and febrile neutropenia. The biomarkers used in antimicrobial stewardship include procalcitonin (PCT), C-reactive protein (CRP), presepsin, and interleukin (IL)-1β/IL-8. The cut-off values vary depending on the disease and study, with a range of 0.25-1.0 ng/mL for PCT and 8-50 mg/L for CRP. Biomarkers can complement clinical diagnosis, but further studies of microbiological biomarkers are needed to ensure appropriate antibiotic selection.

Clinical and pathologic data were reviewed in 20 patients who had have surgery for isolated aortic valvular heart disease between April 1978 and April, 1987. Hospital mortality was 10%, with no additional late mortality during a mean follow-up period of 24.1 months. Prosthetic valve failure developed in 3 patients and two had reoperation. Niety four percent of the survivors who were in NYHA Funtional class III or IV before operation are now in class I or II. Ninety percent of all patients are still alive at a maximum follow up of 9 years. The clinical histories, gross and histologic examination of valves estabilished the causes for isolated aortic valve disease: 3 rheumatic, 2 congenital bicuspid, 2 hypertention, 2 aortitis and each one case of floppy valve, medial cystic necrosis of aorta, bacterial endocarditis. But etiology was unknown in 8 cases. Sixteen patietns had myxoid degeneration, defined as significant disruption of the valve fibrosa and its replacement by acid mucosaccharides and cystic changes. Myxoid degeneration was also the primary pathologic abnormality in the patients with 2 hypertention, 2 rheumatic, 1 aortitis, 1 bacterial endocarditis, 1 floppy valve, 1 congenital bicuspid. The patients with myxoid degeneration of uncertain origin were 8. Histologic finding of all of them revealed nonspecific patients with myxoid degeneration of uncertain orgin were 8. Histologic finding of all of them revealed nonspecific chronic valvulitis with myxoid degeneration. This finding may indicate that the etiology w uld be infectious.
