In the Sharp syndrome we have to do with a mixed collagenosis with symptoms of sclerodermia, erythematodes visceralis, dermatomyositis and rheumatoid arthritis. Above all are observed a Raynaud syndrome, polyarthritis and polyarthralgias, swellings of hands and fingers and myositis and myalgia, respectively. For the ascertainment of the diagnosis as independent picture of a disease the immunological profile is decisive. On the basis of three casuistic cases the author adopts a definite attitude to the Sharp syndrome as independent immunopathy. Questions of diagnostics, therapy and prognosis are discussed.

We describe a 73-year-old forest owner with widespread erythema, myalgia, and proximal muscle weakness. The clinical signs and the results of electromyography, magnetic resonance imaging, and a muscle biopsy were consistent with dermatomyositis. However, serology was positive for Borrelia burgdorferi. More importantly, B burgdorferi DNA was detected in skin by polymerase chain reaction techniques, and spirochete-like organisms were detected in the muscle by silver staining. Lyme disease with muscle involvement can mimic or trigger dermatomyositis and should be considered in the differential diagnosis of dermatomyositis.

Dermatomyositis (DM) is a rare disease of unknown aetiology involving weakness of proximal muscles, myalgia and impairment of the integument. Due to its low incidence, only few reports exist on the anaesthesiologic management of neuromuscular blockade in patients with DM considered for surgical therapy. In this setting, special attention should be given to the administration of muscle relaxants since an increased sensitivity to these drugs in neuromuscular diseases may be expected. METHODS. This case report describes the neuromuscular monitoring of a female patient aged 53 years with DM undergoing strumectomy and treated with methotrexate and prednylidene. Muscle relaxation was induced with 0.35 mg/kg atracurium (1.5 x ED95). An additional bolus of 0.07 mg/kg was administered 50 min later. Control of sufficient relaxation was performed by tactile methods, and time of onset (TO), duration of action (DA) and recovery index (RI) were measured. RESULTS. Relaxation was obtained within TO of 3 min, DA of 50 min and RI of 11 min. These timer indicate slightly increased sensitivity to atracurium. The postoperative outcome demonstrated no muscular weakness and sufficient spontaneous ventilation. DISCUSSION. To date, few experiences of neuromuscular blockade with atracurium in DM have been presented, hence this report. In addition, no standard recommendations are given regarding the application of nondepolarizing muscle relaxants in this context. In our case, atracurium could be implemented as a safe drug under neuromuscular monitoring.

Neuromyositis defined as the association of dermatomyositis or polymyositis and a neuropathy without any found cause is a very controversial entity because of the possibility of, in one hand, muscular modifications caused by neurological involvement and, on the other hand, neurogenic type manifestations caused by polymyositis. The study of 4 cases seen in an Internal Medicine department and the review of the literature allowed us to show that the concept of neuromyositis corresponds to a clinico-pathological reality when the diagnosis is based on the association of definite criteria of both primary muscle and nerve involvement excluding muscular abnormalities that could be the consequence of nerve involvement and vice versa. The criteria, most relevant when associated are: a) for muscular involvement: high increase of muscular enzyme over 6 times the superior limit of the normal values, pseudomyotonic electrical discharges, perifascicular atrophy, intense inflammatory infiltrates and massive necrosis, b) for neurological involvement: early abolition of tendinous reflexes in a patient without notable muscular atrophy and with little or no myalgia, sensitive abnormalities in areas other than those of muscular involvement, especially when they are intense, early weakness of distal muscles, decrease of nerve conduction speed, target fibers and lesions of nerve trunks (and albuminocytological dissociation in the particular case of polyradiculoneuritis). Once the diagnosis of neuropathy settled, it is necessary to exclude an usual cause (alcoholism, diabetes...) before concluding to neuromyositis. When we apply these restrictive (but nevertheless necessary for the validity of diagnosis) criteria, only 6 cases of the literature respond to this entity. It is a peripheral neuropathy in 5 cases (like two of ours) and a polyradiculoneuritis in one case (like our two others). Among these 6 cases, there is a vasculitis in two, frequency much higher to what is observed in adult polymyositis, which suggest a possible causative role of vascular involvement in neuropathy arising. In the other cases we can just give pathogenic hypothesis making the neuropathy and the polymyositis the result of the same process (immunological disturbance, paraneoplastic origin, viral disease). In one of our four patients, who have shown an HTLV-I infection by polymerase chain reaction in situ hybridization was positive in muscle which suggest a direct pathogenic role of the virus. HTLV-I infection should be considered as a possible cause of neuromyositis especially in endemic areas.

Some patients of dermatomyositis (DM) with interstitial pneumonia (IP) have common clinical features. Clinical features of these patients are acute onset, very poor prognosis and that patients have fever, arthritis, typical skin rash, mild myositis and show low ratio of CPK/LDH, low incidence of antinuclear antibody (ANA) appearance, low inflammatory signs. We experienced two cases of this category of DM with IP and examined immunological aspects. Case 1. A 52-year-old woman was admitted in June 1, 1990 with a one-month history of arthralgia and a ten-days history of fever, skin rash, myalgia and dyspnea on exertion. On examination she had Gottron's papules on her fingers, erythema on back, bilateral elbows and legs, proximal muscle weakness and arthritis. Fine crackles were audible in the lower lung fields. Laboratory data included CPK 200 IU/l, ALD 3.2 IU/l, LDH 805 IU/l. Analysis of bronchoalveolar lavage fluid (BALF) revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid (CS), pulse CS, cyclosporin A. Inspite of these therapies, she died of progressive respiratory insufficiency in July 10, 1990. Case 2. A 23-year-old woman was admitted in April 1, 1991, with a two-month history of arthralgia and a one-month history of fever, skin rash, stomatitis, alopecia. On examination she had Gottron's papules on her fingers, erythema on malar, bilateral elbows and legs, arthritis and stomatitis. Laboratory data included CPK 97 IU/l, ALD 8.5 IU/l, LDH 779 IU/l. She began experiencing dry cough and dyspnea on exertion in May 1991. Analysis of BALF revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid(CS), pulse CS, pulse cyclophosphamide.(ABSTRACT TRUNCATED AT 250 WORDS)

Between 1983 and 1992, 11 children and 38 adults were seen at Taichung Veterans General Hospital with a definite diagnosis of dermatomyositis. Their clinical pictures, laboratory findings, courses and outcomes were compared. The mean age at diagnosis was 12 years and 50 years, respectively. Children had a higher female-to-male ratio (2.7:1 vs. 1.2:1) and a more acute onset, while adults had a higher incidence of malignancy and other connective tissue disease associations. Clinically, shawl sign was more common in the adults, whereas myalgia was more frequently seen in the children (0.05 < p < 0.1). Hemograms, serological parameters and immunological investigations showed no significant differences between the two groups. Elevated erythrocyte sedimentation rate and circulating immune complexes were found in over half of both groups of patients; however, their values bore no relationship to either disease activity or future outcome. Although no significant differences were demonstrated between the two groups of patients with regard to either clinical manifestations or laboratory findings, the disease entity seemed not to be the same because evidence of vasculopathy in muscle pathology was more prominent in the children, with endothelial swelling and necrosis the most common findings. Steroids had been used as the first choice of therapy in both groups of patients, followed by cytotoxic drugs and immunosuppressants. Children had a more favorable outcome compared to a 24% mortality rate in the adult group. Experience here recommends a complete cancer work-up in adults, especially for nasopharyngeal carcinoma among the Chinese. Various autoantibodies screenings may also be helpful for early detection of other associated connective tissue diseases.

Dermatomyositis is an acquired disease characterised by symmetric predominantly proximal muscle weakness of the arms and legs, and misery. It may be associated with myalgia and there is often a characteristic rash. The mainstay of therapy is corticosteroids. Recently efficacy of intravenous immunoglobulin (IVIg) in chronic refractory dermatomyositis was reported. Because corticosteroids can cause serious side effects, we treated a seven-year-old girl suffering from dermatomyositis with IVIg as initial therapy. After two courses of IVIg infusions at a dose of 0.4 g/kg/day for five consecutive days, the patient made a rapid and complete recovery. This case shows that IVIg may be effective as initial therapy in patients with dermatomyositis. Whether IVIg is really a better treatment than corticosteroids should be investigated in a randomised study.

Systemic lupus erythematosus, chronic cutaneous lupus erythematosus and subacute and acute cutaneous lupus erythematosus are associated with distinct cutaneous manifestations, and each disease has a particular clinical course and prognosis. Dermatomyositis, an immune-mediated disorder of unknown etiology that is often associated with a malignancy, consists of an inflammatory myopathy combined with characteristic cutaneous findings. Some patients with dermatomyositis also have clinical features that overlap with those of systemic lupus erythematosus or scleroderma. Manifestations of scleroderma range from cutaneous involvement alone to multisystem internal disease. Morphea, progressive systemic sclerosis, eosinophilic fascitis, eosinophilia myalgia syndrome and mixed connective tissue disease are all within the spectrum of scleroderma.

This paper deals with the question of the clinical circumstances in which MRI seems to be promising in patients with myalgia. 241 patients suffering from myalgic symptoms were examined by axial scans of the muscular system with T1w and STIR-sequences. All patients underwent a complete neuromuscular examination, which included an MRI guided muscle-biopsy of 203 patients. The images were retrospectively analysed as to the typical characteristics of differential diagnosis. In cases of idiopathic or bacterial/viral induced myositis, primary vasculitis, and rhabdomyolysis, edematous changes of the muscles could always be found. Abscesses were only found in bacterial myositis. In cases of poly- and dermatomyositis as well as inclusion-body-myositis, MRI showed a uniform distribution pattern with emphasis on the quadriceps muscles. In contrast to other neuromuscular diseases in bacterial induced myositis, focal myositis, and rhabdomyolysis a strong contrast agent enhancement was seen. All patients with myalgic syndromes without any other additional neuropathological findings and 86% of the patients suffering from polymyalgia rheumatica had normal MR-findings. MRI allows a correct exclusion of an inflammatory, tumorous, or rhabdomyolitic cause of a myalgia and leads to pathognomonic findings for these diseases. Diseases belonging to the group of endocrine, toxic, or metabolic myopathies might be normal in MRI. We believe that an indication for MRI is given when muscular pain is associated with additional neuromuscular symptoms, especially if an inflammatory origin of the myalgia is suspected or if a muscle biopsy is planned.

We report a case of dermatomyositis (DM) in a 15-year-old female with toxoplasmosis after ingestion of raw bovine liver. Facial erythema and cervical lymphadenopathy preceded myalgia and muscle weakness of the extremities. The diagnostic criteria of DM was fulfilled because of symmetrical and proximal dominant muscle weakness, elevation of myogenic enzyme (CPK, GOT, LDH, myoglobin, aldorase), myogenic pattern of electromyogram, skeletal muscle biopsy showing interstitial myositis with mild destruction of muscle fiber, and facial erythema. Immunological findings showed IgG anti-toxoplasma antibody to be 1340 IU/ml and IgM to be 7.0 (Cut off index 0.7), suggesting acute toxoplasmosis. Treatment with prednisolone for DM and acetylspiramycin for toxoplasmosis was successful. Toxoplasmosis should be considered as a possibility in patients with myositis.
