It is contended in this report that the majority of pain syndromes involving the neck, shoulders, and low back are the result of a benign, reversible process in the musculature which is psychosomatic in nature and which has been called tension myositis. The natural history of the disorder, findings on physical examination, and diagnostic studies are briefly described. The theoretical basis for the conclusion that it is psychosomatic is discussed, the therapeutic program is described, and long-term results with a group of treated patients are presented. The results suggest that a program of physician counseling and physical therapy is generally successful. The author believes that the psychosomatic nature of the disorder places it within the purview of the behaviorally oriented specialty of family practice.

The clinical, pathological and radiological features and the differential diagnosis of the very rare condition of non-traumatic myositis ossificans circumscripta are illustrated by one patient. The characteristic radiological appearances make a correct diagnosis of this localised, non-malignant process possible.

A case of myositis ossificans traumatica has been reported. Clinical, histopathologic, and roentgenographic entities have been referred to. An up-to-date review of the literature on this disorder has been presented.

A report is given on a case of proliferative myositis in a 75 year old woman. By fine structural analysis it can be shown, that the characteristic giant cells in proliferative myositis are mesenchymal cells with an intensive protein metabolism. They can be compared to fibroblasts; for a myogenic origin of these cells we found noevidence. Furthermore, various stages in the development and function of the proliferating cells were observed, by which the course of the disease can be expalined.

Inclusion body myositis is characterized by an insidious onset, progressive indolent course, and is generally felt to be refractory to standard therapy for myositis. We reviewed the charts of 32 patients with muscle biopsy findings suggestive of inclusion body myositis. The average time from symptom onset to diagnosis was 37 months, but initially 40% were incorrectly diagnosed. Twenty-eight patients (88%) were classified as definite or probable inclusion body myositis and were treated with various combinations of prednisone and immunosuppressive agents. Sixty-eight percent of those treated experienced a decrement in function and muscle strength. Three patients exhibited longterm improvement while 12 patients experienced delayed progression, defined by short term improvement in strength or a stable functional class, All of these patients received therapy, 5 in the form of methotrexate and prednisone. All untreated patients deteriorated clinically. In summary, (1) inclusion body myositis is a clinically distinct entity which is frequently misdiagnosed initially. (2) While clinical improvement with therapy is rare, our observations support recent reports that therapy may be associated with a slower rate of clinical progression. (3) Optimal therapy remains uncertain, but the use of low dose methotrexate and prednisone may warrant further study.

In this study we analysed by immunohistochemistry the expression of p53 protein in 14 malignant fibrous histocytomas (MFHs), 22 other types of sarcoma (eight leiomyosarcomas, four rhabdomyosarcomas, four liposarcomas, two fibrosarcomas, two chondrosarcomas, one malignant schwannoma, and one dermatofibrosarcoma protuberans), and 25 non-malignant mesenchymal lesions (eight dermatofibromas, four cases of nodular fasciitis, three leiomyomas, three fibromatoses, two epithelioid.leiomyomas, two neurofibromas, one schwannoma, one myositis ossificans, and one giant cell tumour of tendon sheath). Four MFHs and nine other types of sarcoma (four leiomyosarcomas, two chondrosarcomas, one liposarcoma, one fibrosarcoma, and one dermatofibrosarcoma protuberans) showed nuclear positivity for p53. Of the benign soft tissue lesions, p53 positivity was observed in two fibromatoses, one nodular fasciitis, and one dermatofibroma. The number of p53-positive cells in these benign lesions was considerably smaller than that in most of the p53-positive sarcomas. The p53 positivity in MFHs and other types of sarcoma indicates that p53 gene alterations may play a part in the neoplastic transformation of these tumours. The occurrence of p53 positivity in benign mesenchymal lesions suggests that sometimes p53 protein may accumulate in cells without an associated malignancy. Because of this, p53 immunoreactivity cannot, by itself, be used as a criterion of malignancy. According to our results, p53 positivity in over 1 per cent of tumour cells in mesenchymal lesions favours malignancy.

Localized nodular myositis was recognized in an elderly man six months prior to the diagnosis of Hodgkin's disease. Meticulous search of the muscle specimen failed to disclose tumorous involvement. The possible paraneoplastic nature of localized nodular myositis in this patient is discussed.

The authors report a case of pseudotumoral focal myositis found in a 55 year-old man, in the anteroexternal area of the right leg. The diagnosis was based on the pathological findings, the absence of any further clinical signs or laboratory findings, and no further development over time. They compare their patient's characteristics with cases found in the literature (24 cases during the past 20 years). Diagnostic certainty confirms the benign character of this pathology, which contrasts with the gravity of the classical form of polymyositis.

Exertion-related muscle pain is frequent in athletes and patients alike; however, its severity and significance may be difficult to assess clinically. MRI can be used to evaluate myalgia, strains, delayed-onset muscle soreness, chronic muscle overuse syndromes, muscle contracture, and sequellae of muscle injuries such as myositis ossificans and compartment syndrome. MRI documents the distribution of affected muscles, the presence of focal hematoma, fascial herniation, and subsequent healing, fibrosis, or fatty infiltration. MRI is useful in evaluating acute and delayed exertional muscle injuries.

The Wisconsin Division of Health (DOH) began surveillance for severe illnesses associated with group A beta-hemolytic streptococcus (GABS) infections in late 1989 to describe the current epidemiologic features and clinical spectrum of these infections in the state. Severe illness was defined by the isolation of GABS from the blood or by the development of one or more of the following in a patient infected with GABS: shock, extensive tissue injury, desquamating rash, disseminated intravascular coagulation, renal failure, adult respiratory distress syndrome, or death. Case reports involving 28 patients with severe GABS-related illnesses with onset from November 1989 through October 1990 were received by the DOH. The majority of the case-patients had sepsis (57%), cellulitis (50%) or both. Nine (32%) cases were fatal. Those who died were older than those who survived (median age 74 years v 43 years, p = 0.002) and were more likely to have clinical diagnoses that included pneumonia (relative risk [RR] 3.0, 95% confidence interval [CI] 1.2, 7.3) or necrotizing fasciitis/myositis (RR 3.7, 95% CI 1.5, 9.0). The median interval from illness onset to hospitalization was similar for fatal cases (1 day) and non-fatal cases (2 days), suggesting that early intervention after the appearance of clinical illness may not improve the outcome.
