Pyomyositis. Increasing recognition in temperate climates.

Pyomyositis is common in the tropics yet is rarely reported in temperate climates. A woman in whom pyomyositis developed in a temperate climate is presented. Computed tomography was the key in the diagnosis of the disease involving the muscles of the left lateral chest wall. The patient's condition responded to intravenous antibiotics and open abscess drainage. The 31 cases reported in the United States are reviewed. Unfamiliarity still poses a barrier to early diagnosis, although pyomyositis is being more frequently described in temperate climates.

Pyomyositis in an adolescent female athlete.

A case of pyomyositis in a healthy 13-year-old female volleyball player is presented and discussed. This case is unusual because, historically, pyomyositis has been more common in males, especially those who participate in strenuous physical activity. However, competitive sports and vigorous exercise programs are becoming more widely available to young females. Therefore, a relative increase in the number of adolescent women with pyomyositis can be expected.

Intracranial suppuration complicating tropical pyomyositis. Report of two cases.

Tropical pyomyositis complicated by intracranial abscesses is described in two Nigerian male patients, aged five and 50 years. In both cases, the lesions were verified at autopsy. The occurrence of brain abscesses in pyomyositis is briefly reviewed. The complication may not be as rare as previously thought and this will appear if port-mortem examination is performed on most, possibly all, fatal cases of pyomyositis.

Tropical pyomyositis in eastern Ecuador.

In the ten year period 1980-1989, 97 patients were treated for tropical pyomyositis at Hospital Vozandes Oriente in eastern Ecuador, accounting for 2.2% of surgical admissions. Operation records from an affiliated hospital in Quito showed that, high on the Andean plateau, pyomyositis accounted for only 0.1% of surgical admissions. Among the patient population of Ecuador's eastern tropical rain forest, persons who were members of an indigenous ethnic group were affected with pyomyositis twice as often as would be expected from their representation in the general population.

Bacterial pyomyositis in the United States.

The incidence of reported bacterial pyomyositis is increasing in the United States, especially among immunocompromised persons. This review summarizes all reported cases of pyomyositis among human immunodeficiency virus (HIV)-infected persons worldwide and HIV-negative persons in the United States since 1981. During the era of combination antiretroviral therapy, bacterial pyomyositis among HIV-infected persons typically occurred in those with end-stage acquired immunodeficiency syndrome. Among non-HIV-infected patients, about half have a serious underlying medical problem, most commonly diabetes mellitus, malignancy, or a rheumatologic condition. These patients are more likely to have a gram-negative infection, a normal white blood cell count, multifocal involvement, or higher mortality than those without an underlying medical condition. The characteristics of cases in temperate areas are similar to tropical cases, except that the former occurs more often in immunocompromised persons; this may change with the HIV epidemic in tropical regions.

Multifocal pyomyositis in an immunocompetent patient.

Pyomyositis is defined as suppurative infection of the skeletal muscle and usually occurs in immunocompromized patients. We managed a 23-year-old man admitted for myalgia and evidence of infection, with onset after a strenuous physical activity. Numerous muscles were involved. Multiple abscesses were visualized by ultrasonography and computed tomography, with predominant involvement of the pelvic muscles. Examination of the aspirate from a forearm abscess recovered Staphylococcus aureus. No factors associated with immunodeficiency were found. Appropriate antimicrobial therapy ensured complete resolution of the infection. Pyomyositis is rare in immunocompetent individuals. Myalgia, fever, and rhabdomyolysis should suggest pyomyositis. Computed tomography and magnetic resonance imaging are the best investigations for confirming the diagnosis.

Anterior tibial compartment syndrome due to the pyomyositis in a patient with rheumatoid arthritis. A case report.

Anterior tibial compartment syndrome was developed due to pyomyositis in a 33-year-old male patient with rheumatoid arthritis while receiving steroid therapy during the follow-up period. The preoperative physical examination, laboratory findings, MRI images, intraoperative observation and postoperative histopathological examinations confirmed the association with pyomyositis. The surgical drainage and antibiotic treatment were effective, and in the follow-up period, neuromuscular dysfunctions disappeared completely within 6 months. The patient has been asymptomatic for 4 years of follow-up. To date, anterior tibial compartment syndrome due to pyomyositis in a case with rheumatoid arthritis has not been reported.

Pyomyositis during induction chemotherapy for acute lymphoblastic leukemia.

Herein, we report on the correct diagnosis and effective treatment procedures for pyomyositis, a very rare complication that remains a diagnostic challenge in children being treated for acute lymphoblastic leukemia (ALL). We report the case of a 10-year-old girl suffering from pyomyositis with ALL. Correct diagnosis is usually delayed because the initial symptom of pyomyositis, usually local pain, is similar to the common side effect of vincristine, a drug necessary for ALL induction therapy. We summarize the procedures taken to reach a timely diagnosis and therapeutic success.

[The non-tropical pyomyositis--a rare disease in the moderate climate zone].

Pyomyositis is in the moderate climate zone a rare and acute bacterial infection of the skeletal muscles without an obvious origin of infection. Initial symptoms contain muscle pain and localized swelling and tension. As different causes are taken into account first, the diagnosis of a pyomyositis is often delayed. We report on three cases of pyomyositis and discuss diagnosis and therapy against the background of the available and recent literature.

Gram-negative bacterial pyomyositis: unique case and review.

Bacterial pyomyositis in tropical or temperate climates is usually associated with gram-positive organisms, and Staphylococcus aureus has been recovered most often. In contrast, skeletal muscle infection due to aerobic gram-negative bacteria is an acknowledged rarity, even in tropical areas. A literature review revealed only five organisms implicated in gram-negative pyomyositis in the United States; to this list, we add a unique case of pyomyositis caused by Serratia marcescens that occurred in a patient with multiple myeloma. Although the data are limited, it appears that lower leg muscles are more likely to be involved and that clinical cure is often achieved following appropriate drainage and antibiotic therapy.

Pyomyositis in patients with diabetes mellitus.

Pyomyositis is a pyogenic infection of skeletal muscle that is endemic in the tropics and is being recognized with increasing frequency in temperate climates. We report two cases of nonendemic pyomyositis in patients with diabetes mellitus. A review of the literature suggests that diabetes mellitus may be an important risk factor for the development of pyomyositis. Possible mechanisms of this association are discussed.

Salmonella pyomyositis in patients with the human immunodeficiency virus.

Pyomyositis is a common disease in the tropics, mostly due to Staphylococcus aureus. We report two patients infected with the human immunodeficiency virus (HIV) who presented with fever and unilateral limb swelling and in whom pyomyositis was diagnosed in quadriceps and gluteus major, respectively. Salmonella enteritidis was isolated in both, with recurrent episodes of muscle involvement and secondary osteomyelitis in one case. Non-typhi Salmonella pyomyositis may occur in HIV + patients with a relapsing and aggressive clinical course in some cases.

Pyomyositis with hepatic and perinephric abscesses caused by Candida albicans in a diabetic nephropathy patient.

Both disseminated candidiasis and pyomyositis are rare and mainly encountered in severely immunocompromised hosts. To our knowledge, Candida albicans related pyomyositis with formation of multiple visceral abscesses in a diabetic nephropathy patient has never previously been reported. A 47-year-old man with diabetic nephropathy and alcoholic liver disease developed disseminated candidiasis, with the initial presentation of pyomyositis. Debridement was performed and intravenous fluconazole commenced. Despite development of a single hepatic and multiple perinephric abscesses, the patient made a full recovery after completion of a 12-week course of intravenous fluconazole therapy. Candida species should be considered a potential pathogen in patients with predisposing factors.

Streptococcal pyomyositis: case report and review.

Pyomyositis is most often associated with Staphylococcus aureus infections after trauma. We describe an unusual presentation of pyomyositis of the chest wall secondary to group A betahemolytic streptococcus infection in a 15-month-old child with acute abdominal symptoms. In addition, the patient had no history or evidence of trauma to the affected area. Pyomyositis presenting in this manner secondary to group A beta-hemolytic streptococcus infection in the absence of a primary varicella infection has not been previously reported.

Pneumococcal pyomyositis: a patient with diagnostic problems and complications.

Pyomyositis is an uncommon condition that may present a difficult problem in diagnosis. We report the development of Streptococcus pneumoniae pyomyositis involving the iliacus, iliopsoas, and gluteus muscles in a patient with elevated serum levels of antinuclear and antiphospholipid antibodies but without clinical evidence of connective tissue disease. Magnetic resonance imaging demonstrated rapid evolution of the infection, with progression from muscle edema to abscess formation over a period of 10 days. The diagnosis was initially missed, and osteomyelitis and sacroiliitis developed. Pyomyositis should be suspected in patients with the acute onset of severe, localized muscle pain and fever. As in this case, failure to promptly diagnose and treat this infection can result in significant morbidity.

Nontropical pyomyositis in an immunocompetent host.

Pyomyositis is a primary infection of the striated muscle. We describe the clinical and imaging features of 2 cases with nontropical pyomyositis in immunocompetent hosts. Staphylococcus aureus was the causative agent; the treatment included antibiotics and either computed tomography or magnetic resonance-guided percutaneous needle drainage, avoiding open drainage. This treatment modality was successful with complete recovery of movement. Because of the rarity of pyomyositis in temperate climates, the common lack of specific signs or symptoms, and the frequent negative blood cultures, considerable delay precedes the diagnosis. Fever, elevated erythrocyte sedimentation rate, and muscle stiffness are diagnostic clues. Increased awareness, especially in immunocompetent hosts, should lead to earlier diagnosis and treatment with improved outcomes. Diagnosis and treatment can be reached at the same time in some cases by image-guided percutaneous drainage.

Non-tropical pyomyositis in children--with report of severe neurological complications.

Pyomyositis appears to occur rarely in temperate climate areas, compared with the incidence of the disease in the tropics. Three young adults with pyomyositis have previously been described in Israel, two of them were newly arrived Ethiopian immigrants. We report three Israeli children with pyomyositis, who presented initially with nonspecific abdominal pain; in one child the course was complicated by spinal cord compression due to extension of the infected mass into the spinal canal. All three patients attained full recovery after antibiotic therapy and surgical drainage. Computed tomography was most valuable in establishing the diagnosis and defining the extent of the process.

Bacterial pyomyositis in a patient with aplastic anaemia.

Bacterial pyomyositis is common in the tropids but is rare in temperate climates. A patient with aplastic anaemia who had never left the continental United States developed bacterial pyomyositis secondary to Staphylococcus aureus which responded to antibiotics and surgical drainage. Bacterial pyomyositis should be considered in the differential diagnosis of fever and myalgias in the immunocompromised patient.
