1/15. Primary haemophilus influenzae pyomyositis in an infant: a case report.

    Promyositis is a term used to denote primary pyogenic infection of the skeletal muscle. Because striped muscle tissue is normally resistant to bacterial infection, pyomyositis is very rare. In tropical countries, pyomyositis accounts for about 4% of hospital surgical admission, but it is far less common in temperate climates. It is more common in adults and especially in men, but it can occur at any age. We would like to present an 8-month-old infant to make pediatricians aware of the possibility of pyomyositis in cases of a mass over muscle, or of children complaining of joint pain or muscle aches even in the infancy period.

2/15. pyomyositis in north america: case reports and review.

    We report two cases and review the characteristics of pyomyositis. The courses of patients who presented with pyomyositis at the Maricopa Medical Center (Phoenix) are detailed. Ninety-eight reported cases over the last 20 years in north america, found through a medline search, are summarized. Infection with the human immunodeficiency virus (hiv) may predispose the patient to pyomyositis. The onset is usually insidious with progression to large purulent collections and significant morbidity. The diagnosis is frequently suggested by findings of imaging studies. staphylococcus aureus is responsible for most cases in tropical areas but is less frequently associated with cases in north america. Since infection with hiv predisposes patients to bacterial infections, pyomyositis will occur more frequently in this patient population. Increased awareness of the disease will improve management. Following aspiration or surgical drainage, therapy with broad-spectrum empirical antibiotics may be considered initially in the treatment of pyomyositis.

3/15. Necrotising fasciitis and myositis that originated from gastrointestinal bacterial infection: two fatal cases.

    We present two cases of aggressive myofasciitis after gastrointestinal infections. The first patient developed necrosis of the legs over 5 days and he died on the 20th day. vibrio vulnificus was cultured. The second patient developed bullae on his thigh and he died the next day. streptococcus pyogenes was cultured.

4/15. pyomyositis in a 69-year-old tennis player.

    pyomyositis is an acute bacterial infection of skeletal muscle usually caused by staphylococcus aureus. Outside of tropical areas, pyomyositis is rare, especially in an otherwise healthy individual. We present a case of a 69-year-old tennis professional who developed pyomyositis of the piriformis muscle following a tennis tournament. We discuss the literature on pyomyositis and the need for high clinical suspicion in the diagnosis of this disorder, as well as the need for early aggressive antibiotic treatment.

5/15. Spontaneous pyomyositis and AIDS: an infrequent association.

    pyomyositis is an acute bacterial infection of striated muscle. It is common in the tropics, but rarely reported in temperate climates. We present two cases in patients with the acquired immune deficiency syndrome (AIDS), one an active homosexual, and one an intravenous drug user. A brief review of the clinical findings and diagnostic procedures is included. We conclude that pyomyositis should be included in the list of locations of pyogenic infections that can occur in AIDS patients.

6/15. pyomyositis in patients with the human immunodeficiency virus: an unusual form of disseminated bacterial infection.

    PURPOSE AND patients: pyomyositis, a common disease in the tropics, is rare in the continental united states, with approximately 83 cases described in the literature in the past two decades. The occurrence of pyomyositis complicating human immunodeficiency virus (hiv) infection has been reported in 10 patients since 1986. We report six cases of this entity in patients with advanced hiv disease seen in our institution over a 20-month period. A common denominator in all of our patients was muscle injury, induced by either exercise or trauma. Unlike most previous reports of hiv-associated pyomyositis, the clinical picture in our cases was complicated by the development of abscesses in multiple muscle groups, requiring prolonged antimicrobial therapy and repeated drainage procedures for successful management. Interestingly, one patient developed concomitant rhabdomyolysis--an otherwise rare event in classical pyomyositis. staphylococcus aureus was the predominant infecting organism in this as well as all other series. Of note, we also observed and report the first case, to our knowledge, of gram-negative pyomyositis in an hiv-infected individual. The pathogenic implications of this catalase-producing gram-negative isolate are discussed in the context of neutrophil abnormalities in hiv disease. CONCLUSION: Like tropical pyomyositis, its hiv-associated counterpart appears to be multifactorial in origin. Its recent recognition suggests that, in addition to underlying abnormalities of host defense, factors relating to the prolonged survival of patients with late-stage disease, including myopathy, might play an important contributory role.

7/15. pyomyositis secondary to group A beta hemolytic streptococcus.

    pyomyositis is a primary bacterial infection of skeletal muscle not formed by local extension from superficial tissues. It is relatively frequently seen in tropical climates but reportedly rarely seen in temperate climates such as North America. In this report, we present a 67-year-old man with a primary Group A beta hemolytic Streptococcal infection of the quadriceps muscle of the left leg.

8/15. pyomyositis and human immunodeficiency virus infection.

    pyomyositis is a bacterial infection of skeletal muscle usually caused by staphylococcus aureus and characterized by localized muscle pain, swelling, and tenderness. The disease is endemic in the tropics. Though only approximately 50 cases have been reported from the continental united states, pyomyositis has been increasingly recognized here in the last decade. We report two patients with human immunodeficiency virus (hiv) infection and pyomyositis, and review five previously reported cases. Given the predisposition of patients with the acquired immunodeficiency syndrome (AIDS) or aids-related complex (ARC) for infections caused by S aureus, pyomyositis may become increasingly more common in temperate areas.

9/15. pyomyositis in a patient with the acquired immunodeficiency syndrome.

    pyomyositis is an acute bacterial infection of skeletal muscle. It is a common disease in the tropics; fewer than 50 cases of pyomyositis have been reported in the continental united states. Most patients are healthy males, although the disease has been reported in diabetics and in the immunocompromised. This article presents the first detailed known reported case of pyomyositis in a patient with the acquired immunodeficiency syndrome; staphylococcus aureus was the etiologic agent.

10/15. pyomyositis.

    pyomyositis is a bacterial infection of skeletal muscle that is usually accompanied by abscess formation. staphylococcus aureus is the most common causative organism. pyomyositis should be suspected in any patient who presents with fever, muscle pain and leukocytosis. It is confirmed by needle aspiration and culture of the suspected muscle group. Treatment entails incision and drainage of abscesses and appropriate antibiotic therapy.
