Purulent myositis

This disease is an abscess formed deep inside the large striated muscle.
Muscular and skeletal abscesses are uncommon, and they can be caused by the expansion of adjacent bone or soft tissue infections or spread through the bloodstream. Septic myositis is very rare in the United States, but can occur in immunocompromised patients, especially those with AIDS. In many tropical regions, the disease can often occur in children and adults, especially those who are malnourished. The mechanism is believed to be bloodborne spread, which may be caused by bacteremia, a localized infection in previously injured muscles, However, previous trauma is often overlooked. The most common sites are quadriceps, gluteus, shoulder and upper limb muscles. Multiple abscesses can occur in about 40% of cases.
The initial symptoms are spasmodic pain, followed by edema and increasing discomfort and low fever. At this time, muscle stiffness can be seen. Later, edema and tenderness increase, and about half of the cases show significant fluctuations. Leukocytosis is common. In the early stages of muscle stiffness, use Acupuncture pumping may be negative, and thick yellow pus can be formed in the future. Staphylococcus aureus almost always grows in culture. Occasionally, a few cases are caused by Streptococcus pyogenes or E. coli.
Treatment with penicillin-resistant penicillin. In the non-purulent period, antibiotics alone are effective for purulent myositis. If there is pus, it must be incised and drained. The range of involvement seen during surgery is often larger than the preoperative clinical estimates Much more.
