1/7. pyomyositis in the acquired immunodeficiency syndrome.pyomyositis, a purulent infection of skeletal muscle, is usually caused by staphylococcus aureus. Many cases of pyomyositis in human immunodeficiency virus (hiv) seronegative patients have been reported in north america and have been reviewed extensively. Moreover, pyomyositis has been reported in association with hiv infection in patients with or without the acquired immunodeficiency syndrome (AIDS). We describe two patients with pyomyositis and hiv and review the available English language literature. leukocytosis and bacteremia tend to occur less frequently in those with hiv infection and pyomyositis. However, fever, S aureus infection, and bilateral involvement occur more frequently in hiv-positive patients. Antibiotic therapy together with surgical drainage or aspiration is usually sufficient.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
2/7. Analysis of a viridans group strain reveals a case of bacteremia due to lancefield group G alpha-hemolytic streptococcus dysgalactiae subsp equisimilis in a patient with pyomyositis and reactive arthritis.streptococcus dysgalactiae is classified by a combination of phenotypic and genotypic characteristics into Lancefield group C alpha-hemolytic streptococcus dysgalactiae subsp. dysgalactiae and Lancefield group C, group G, and group L beta-hemolytic streptococcus dysgalactiae subsp. equisimilis. In this study, we report the isolation of a catalase-negative, alpha-hemolytic, optochin- and bacitracin-resistant viridans group strain, which does not grow in 10 or 40% bile, on MacConkey agar or bile esculin agar, or in 6% NaCl, from the blood culture of a 73-year-old woman with pyomyositis and poststreptococcal reactive arthritis. Lancefield grouping revealed that the strain was a group G streptococcus. The Vitek system (GPI) showed that it was unidentified, and the API system (20 STREP) showed that it was 95.7% S. dysgalactiae subsp. dysgalactiae. 16S rRNA gene sequencing showed that it was a strain of S. dysgalactiae. Based on phylogenetic affiliation with 16S rRNA gene or GroEL amino acid (another bacterial gene, in addition to 16S rRNA gene, that is highly conserved) sequences, the strain is most closely related to Lancefield group C beta-hemolytic S. dysgalactiae subsp. equisimilis. PCR amplification and sequencing of the streptolysin S structural gene (sagA) and M protein gene (emm) hypervariable region showed the presence of these suspected primary virulence factors. Further studies would delineate whether the isolate is just a hemolysin-deficient variant of group G beta-hemolytic S. dysgalactiae subsp. equisimilis or a novel type of S. dysgalactiae. The present case showed that group G alpha-hemolytic S. dysgalactiae subsp. equisimilis can be associated with serious invasive infection and poststreptococcal sequelae.- - - - - - - - - - ranking = 1.25keywords = pyomyositis (Clic here for more details about this article) |
3/7. Purulent pericarditis complicating septicaemia: report of two cases.Intrapericardial (Pericardial) abscess is quite rare as a complication of sepsis and as a cardiac complication of typhoid septicaemia. It is rapidly fatal if untreated. We report two cases of a schoolboy eight years old with septicaemia from pyomyositis of the right thigh and another of nine and a half years with typhoid perforation and typhoid septicaemia that developed pericardial abscesses. In well-developed centres, computerised tomography, ultrasonography and other radiological investigations are employed for both diagnosis and therapy. We emphasise that these can be accomplished by good clinical examination, radiography of chest and the use of 18-G intra-venous cannula for percutaneous pericardiocentesis without aggressive surgical intervention.- - - - - - - - - - ranking = 0.25keywords = pyomyositis (Clic here for more details about this article) |
4/7. Tropical pyomyositis.Although rare, tropical pyomyositis can result from staphylococcal bacteremia and should be considered in the different diagnosis of fever associated with extremity pain. The diagnosis is readily made with a CT scan. Treatment is primarily medical with surgery reserved for refractory abscesses.- - - - - - - - - - ranking = 1.25keywords = pyomyositis (Clic here for more details about this article) |
5/7. pyomyositis: a fatal case in a healthy teenager.pyomyositis is a common disease in the tropics that is reported with increasing frequency in the united states. We describe an unusually fulminant, fatal case in a previously healthy adolescent male. This case illustrates the clinical progression of pyomyositis from localized muscle infection to disseminated disease, and highlights the importance of considering this rare diagnosis in any stage of occult sepsis.- - - - - - - - - - ranking = 0.25keywords = pyomyositis (Clic here for more details about this article) |
6/7. A case of muscle abscess presenting to an accident and emergency department.A case is reported of a patient with acute primary muscle abscess who presented to the accident and emergency department with hip pain. pyomyositis must be considered as a cause of muscle pain especially around the hip. A brief discussion of the diagnosis and management of pyomyositis is also presented.- - - - - - - - - - ranking = 0.25keywords = pyomyositis (Clic here for more details about this article) |
7/7. Pneumococcal pyomyositis secondary to pneumonia.A case of pneumococcal pyomyositis of the brachial and shoulder region is presented. A bacteremic right lower lobe pneumonia was the source of infection. The spread of pneumococci was presumed to be blood-borne, presenting with cellulitis over the right shoulder region, progressing over 5 days to abscess formation in the right biceps muscle and right shoulder joint despite adequate antibiotic treatment.- - - - - - - - - - ranking = 1.25keywords = pyomyositis (Clic here for more details about this article) |
