Benign acute childhood myositis in an Accident and Emergency setting

Benign acute childhood myositis: an alarming condition with an excellent prognosis!

“…Most commonly occur after influenza B and occasionally influenza A infection, but parainfluenza, adenovirus, herpes simplex, Epstein-Barr, Coxsackie, rotavirus, and M pneumoniae have also been implicated [1][2][3][5][6][7][8][9][10], as found in our study. As evidenced, key elements in the diagnosis are a preceding upper respiratory infection followed by the acute onset of typical myositis clinical findings, predominantly affecting gastrocnemius-soleus muscles.…”

“…As evidenced, key elements in the diagnosis are a preceding upper respiratory infection followed by the acute onset of typical myositis clinical findings, predominantly affecting gastrocnemius-soleus muscles. Further clinical features include school-aged boys and late winter-early spring predominance, elevated CK, and aminotransferase levels (especially AST) [1][2][3][4][5][6][7][8][9][10]. Transient hematological abnormalities (mild leukopenia, neutropenia, and thrombocytopenia) are also seen [1,3,[8][9][10].…”

Erythrocyte sedimentation rate and CRP are usually normal but may be mildly elevated [1][2][3]5,6].…”

Benign Acute Childhood Myositis due to Toxoplasmosis

“…The most common presentation of the disease is acute refusal to walk or altered gait during walking. Although the most common etiologic agents are influenza type A and B viruses, the other agents are also reported in the literature [2,3]. Toxoplasmosis is mostly subclinical or asymptomatic infectious disease in healthy children.…”

“…If the CK levels are too high, patient should be monitored in terms of rhabdomyolysis and renal failure [5]. Duration of symptoms are short and the recovery is spontaneous; therefore, further investigations are unnecessary unless the diagnosis is suspected [3].…”
