The first known human case of Trichinella pseudospiralis myositis is described. A 33 years old woman reported 5 years of relatively mild symptoms of tiredness, muscle fatigue and muscle pain after exercise. She had minimal proximal weakness. Creatinine kinase was significantly elevated, and muscle biopsy showed polymyositis and Trichinella larvae. Steroid treatment dramatically worsened the weakness. Treatment with albendazole led to complete resolution of symptoms and laboratory abnormalities. Diagnosis and identification of the parasite were based on the distinctive appearance of the unencapsulated larvae and their movement in fresh muscle, plus clinical and laboratory findings.

Molecular hybridization using an enterovirus group specific probe detected virus RNA in muscle biopsy samples from 25 of 96 cases of inflammatory muscle disease and similarly from 41 of 158 cases of postviral fatigue syndrome (PFS). Enterovirus RNA was detected in only two of 152 samples of control muscle. The inflammatory myopathy group comprised patients with polymyositis (PM), juvenile dermatomyositis (JDM) or adult dermatomyositis (DM), and all showed the presence of an inflammatory infiltrate and fiber necrosis on histological examination of a muscle biopsy sample. In contrast, muscle samples from the PFS group were histologically normal except for non-specific changes such as occasional single fiber atrophy. By analogy with enteroviral myocarditis, which can progress to a post-inflammatory disease with persistence of virus in myocardium and disposes to the rapid development of dilated cardiomyopathy, we propose that PFS syndrome may be a sequela of a previous inflammatory viral myopathy.

Magnetic resonance imaging (MRI) and P-31 magnetic resonance spectroscopy (P-31 MRS) provide unique, quantitative data that cannot be obtained from routine laboratory tests. MRI is the method of choice for imaging of muscle abnormalities. It is also a very sensitive technique for localizing nonhomogeneous inflammation in inflammatory myopathies such as dermatomyositis, juvenile dermatomyositis, amyopathic dermatomyositis, polymyositis, and inclusion body myositis. During treatment of inflammatory myopathies, the extent and severity of inflammation may decrease at varying rates, but weakness and fatigue remain serious clinical problems. The metabolic abnormalities detected with P-31 MRS are more persistent and can be used for objective patient evaluation after the disappearance of inflammation and normalization of serum levels of muscle enzymes. With P-31 MRS, biochemical defects are quantitated, including low levels of ATP and phosphocreatine (PCr) and elevated concentrations of ADP and inorganic phosphate (Pi), which may all be related to weakness and fatigue. Thus, MRI and P-31 MRS are useful in assessing the status of patients with inflammatory myopathies during treatment with prednisone and immunosuppressive drugs.

Dermatomyositis and polymyositis are the two major idiopathic inflammatory myopathies. The Bohan and Peter's criteria are still useful despite the probably different pathogenesis of the two myopathies. Cutaneous manifestations of dermatomyositis include heliotrope rash and Gottron's papules. The heliotrope rash, with or without edema, in a distribution involving periorbital skin is very suggestive of the diagnosis. Papules may be found overlying the "kneedle" of the hand or the elbows, knees, feet. Periungueal erythema with telangiectasis were characteristic but not pathognomonic. Scalp involvement is common. Skin lesions of dermatomyositis may precede the development of the myopathy and may persist after the control of the myositis. Some patients have an amyopathic dermatomyositis with normal muscle-enzyme, magnetic resonance scan and muscle biopsy. Muscle disease affects the proximal muscles, is generally symmetrical and symptoms are fatigue, weakness and sometimes myalgia. Proximal dysphagia reflects an involvement of striated muscle of the pharynx or proximal esophagus. Camptocormia reflects a severe involvement of paravertebral muscle. Other systemic features may be seen: pulmonary involvement (mostly interstitial pneumonitis and hypoventilation), arthralgias or arthritis, cardiac involvement, vasculatis and calcinosis particularly in children or adolescents with dermatomyositis. Malignant disease is associated with idiopathic inflammatory myopathies with a frequency of approximatively 10 to 15% in dermatomyositis and 5 to 10% in polymyositis and is strongly correlated with age, more than 50% of the patient over 65 years old were found to have a cancer. In the absence of malignant disease, the mainstay therapy for dermatomyositis and polymyositis is systemic corticosteroids (mostly 1mg/kg). In the lake of response or high dose dependance, intravenous immunoglobulins or immunosuppressive drugs like methotrexate or azathioprine may be discuss. Cyclophosphamide show some effectiveness in interstitial pneumonitis. Cyclosporin might be effective in children, less in adults. The efficacy of tacrolimus, mycophenolate mofetil, leflunomide and anti-TNF therapy need some prospective studies to determine if there are of value in idiopathic inflammatory myositis.

Relationship among thyroid dysfunction and musculoskeletal symptoms has been known for years. Autoimmunic thyroiditis is the most common cause of hypothyrosis. A patient who suffered from myopathy secondary to autoimmunic thyroiditis and hypothyrosis is described in this article. Attention has been drawn to proximal muscle weakness and general fatigue which is common in such cases. Significant elevation of muscle enzymes is typical. Usually no specific signs can be found on muscle biopsy. Much efforts should be put to distinguish myopathy secondary to hypothyrosis from polymyalgia rheumatica, polymyositis or myopathies caused by other diseases. Similar data of literature are reviewed in the article.

A 38-year-old man had suffered from general fatigue, mild weakness of proximal muscles, and dry cough in November, 2000. Serum levels of muscle enzymes were elevated. Computed tomography of the chest revealed reticular appearance in the bilateral dorsal lung areas. He did not show any improvement, therefore he was referred to our hospital in April, 2001. He was diagnosed as mild polymyositis with mild interstitial pneumonia. He was treated intravenously with methylprednisolone pulse therapy. During the pulse therapy serum level of creatine kinase was decreased, but he died because of acute pump failure of the heart. The cause of the heart failure could be an exacerbation of chronic myocarditis associated with polymyositis and it was confirmed by autopsy findings. When a patient with mild polymyositis complains of general fatigue, myocarditis should be carefully evaluated because of the high risk of death.

The hepatitis C virus (HCV) infection is a worldwide disease that is characterized by a preferential chronic evolution with mild to severe liver disease, including cirrhosis and, in lesser proportion, hepatocarcinoma. Out of these complications, HCV is frequently reported to complicate extrahepatic manifestations. Among those associated to HCV infection with a high degree of certainty, mixed cryoglobulinemia and its complications (skin, neurological, renal, rheumatological involvement) are the most prevalent (50%) in HCV-infected patients. The other diseases include noncryoglobulinemic systemic vasculitis, splenic lymphoma with villous lymphocytes, fatigue, porphyria cutanea tarda, sicca syndrome, and autoantibodies production. The extrahepatic manifestations that share mild-degree certainty of association with HCV infection include B-cell non-Hodgkin lymphoma, autoimmune thrombocytopenia, pruritus, and type II diabetes mellitus. The other diseases such as autoimmune thyroiditis, lichen planus are more questionable for their eventual association with HCV and others (pulmonary fibrosis with or without polymyositis, progressive encephalomyelitis, Mooren's corneal ulcers, erythema nodosum, chronic polyradiculonevritis) are mostly case reports. Howerver, even in cases of tight association, the mechanisms through which HCV may promote or induce extrahepatic manifestations remain unclear and merit further investigations.

A 47-year-old woman with primary biliary cirrhosis and scleroderma was examined at our hospital for a 1-week history of non-resolving fever, arthralgia, myalgia, muscle weakness and fatigue. A diagnosis of systemic lupus erythematosus was made based on arthralgia, low leukocyte count, low lymphocyte count, low serum concentration of complements, positive anti-nuclear antibody and positive anti-double-strand-DNA antibody. She was negative for anti-U1RNP antibody, but positive for anti-Jo1 antibody, and her initial serum concentration of creatine phosphokinase was elevated. We diagnosed her as having overlap syndrome with scleroderma, systemic lupus erythematosus and possible polymyositis associated with primary biliary cirrhosis. Prednisolone rapidly improved her symptoms. Lobulated leukocytes were observed in her peripheral blood specimen. She was positive for anti-HTLV-1 antibody, but Southern blot hybridization did not confirm monoclonal integration of HTLV-I proviral DNA in her peripheral blood. This suggests the possibility of a relationship between HTLV-1 infection and various autoimmune disorders including primary biliary cirrhosis.

Systemic lupus erythematosus (SLE), Sjogren's syndrome (SS), and dermatomyositis (DM)/polymyositis (PM) may be encountered in geriatric patients due to improved survival rates in patients with younger ages of onset or from elderly-onset (EO) disease. EO disease accounts for up to 20% of patients affected by these disorders, and is typically insidious rather than acute. Whereas SS and DM/PM are considered autoimmune diseases with distinct organ specificity, SLE is a systemic disorder that may affect multiple organ systems. Commonly used clinical and laboratory criteria for defining and diagnosing these diseases were largely developed for patients age <65, and need to be modified in the geriatric patient. Therapeutic strategies include attention to ongoing drug regimens, medical comorbidities, and the roles of fatigue, depression, and arthropathy. Each disease may be responsive to low-dose corticosteroids, with a role for first or second-line immunosuppressives as steroid-sparing agents.

Skeletal muscle involvement can occur at all stages of human immunodeficiency virus (HIV) infection, and may represent the first manifestation of the disease. Myopathies in HIV-infected patients are classified as follows: (1) HIV-associated myopathies and related conditions, including HIV polymyositis, inclusion-body myositis, nemaline myopathy, diffuse infiltrative lymphocytosis syndrome (DILS), HIV-wasting syndrome, vasculitic processes, myasthenic syndromes, and chronic fatigue; (2) muscle complications of antiretroviral therapy, including zidovudine and toxic mitochondrial myopathies related to other nucleoside-analogue reverse-transcriptase inhibitors (NRTIs), HIV-associated lipodystrophy syndrome, and immune restoration syndrome related to highly active antiretroviral therapy (HAART); (3) opportunistic infections and tumor infiltrations of skeletal muscle; and (4) rhabdomyolysis. Introduction of HAART has dramatically modified the natural history of HIV disease by controlling viral replication, but, in turn, lengthening of the survival of HIV-infected individuals has been associated with an increasing prevalence of iatrogenic conditions.
