Acne fulminans is characterized by highly inflammatory ulcerative lesions and systemic manifestations. We report a case of acne fulminans and myositis. In addition to having typical skin changes, the patient was unable to walk and electromyographic studies showed significant changes.

The computed tomographic (CT) scans of 11 consecutive patients with orbital myositis were reviewed to better characterize the CT appearance of this condition. The findings in this series differed from those of previous reports in several ways. Multiple muscle involvement predominated. Bilateral involvement was more frequent than previously reported. Enlargement of the tendon as well as the muscle was a frequent finding, but a normal tendinous insertion did not preclude the diagnosis of orbital myositis. Although the CT appearance of orbital myositis is often helpful, the findings are not pathognomonic; correlation with history, clinical findings, and therapeutic response must be considered in making the diagnosis.

A case of proliferative myositis of the masseter muscle in a 62-year-old woman is presented and pertinent literature is reviewed. This benign pseudosarcomatous proliferative lesion has not been previously reported in any of the muscles of mastication. Clinically the patient presented with pain and difficulty in opening of the mouth. On initial examination, a malignant salivary gland tumor was suspected. The proliferative myositis exhibits a disturbing microscopic appearance characterized by the presence of numerous hyperchromatic fibroblasts and oval or spindle-shaped giant cells which resemble malignant rhabdomyoblasts. These lesions have been often misdiagnosed as rhabdomyosarcoma and other types of sarcomas. Awareness of the microscopic characteristics of proliferative myositis and the possibility of its occurrence in the perioral soft tissues is important in avoiding misdiagnosis of this benign condition.

A 13-year-old girl with chronic graft versus host disease (GVHD) developed severe proximal weakness. Muscle biopsy showed necrotic fibers with anti-IgG deposits and interstitial inflammation. Steroid treatment helped, but her weakness recurred. Repeat biopsy showed persistent inflammation and possible steroid myotoxicity. Numerical ratio of capillaries to myofibers and capillary numerical density were higher than childhood dermatomyositis (CD), and capillaries had no tubuloreticular inclusions. Absence of quantitative histologic, ultrastructural, or immunocytochemical abnormalities of capillaries differentiated our patient from CD. We conclude that myositis of chronic GVHD can present as a severe myopathy that responds to steroids and differs from CD.

Fifty patients in severe congestive heart failure (CHF) were treated with captopril (Capoten; Squibb), an oral angiotensin-converting enzyme inhibitor, over a 2-year period (range 3-24 months, mean 8,6 +/- 7,7 months). At entry, all patients were in New York Heart Association (NYHA) functional class IV despite high-dose diuretic and conventional vasodilator therapy. The overall cumulative survival at 6 and 12 months was 64% and 53% respectively. There were 22 deaths (18 during captopril therapy) including 8 sudden deaths. At 2-year follow-up (mean 14,6 +/- 6,9 months), there were 25 survivors on captopril; 18 in NYHA class I or IIS and 7 in class IIM or III. Diuretic requirements were decreased considerably in all. Side-effects were common but transient and in no case did captopril have to be withdrawn. We confirm our earlier conclusion that captopril has long-term beneficial effects and is a highly effective drug in the treatment of patients with CHF refractory to currently accepted therapy. Sudden death despite satisfactory clinical improvement continues to cause concern. Precautions which may reduce or avoid these are briefly discussed.

Hypertriglyceridaemia, an atherogenic risk factor, is a well recognised complication of uraemia, and is present in the earliest stages of the disease. Bezafibrate is an effective hypolipidaemic agent, and its effect in moderate to severe uraemia is documented in this study. Significant reductions in serum triglyceride and cholesterol have been achieved after 1 month's therapy with a reduced dosage of bezafibrate. A reduction in the hyperinsulinaemia was also seen, but no change in the fractional removal rate of injected lipid emulsion (K2) was observed. An accelerated decline in some patients' renal function was observed, which was partially reversed on cessation of treatment. Reversible elevations in the serum creatinine phosphokinase were also seen, but no patient exhibited the myositis-like syndrome associated with clofibrate.

Thirteen patients complained of recent fluctuating aching of one orbit, punctuated by stabbing pains. All had exquisite point tenderness over the trochlea and in half of the patients the pain was aggravated by eye movement. Standardized A-scan echography demonstrated swelling of the peritrochlear tissue and thickening of the superior oblique muscle with low internal acoustic reflectivity, typical of myositis. CT scan showed a soft tissue density in the region of the trochlea. Biopsy, performed on two patients, revealed peri-trochlear inflammation. In all patients the symptoms resolved within a period of weeks or months: indomethacin or naproxen were not effective, but oral or locally injected corticosteroids shortened the course compared to no treatment. None of the patients had ptosis, proptosis, Brown's syndrome, or a click, nor did they have echographic or radiographic signs of sinusitis or inflammation away from the trochlea. This probably represents a highly localized subtype of idiopathic orbital inflammation ("pseudotumor").

Twenty-seven adult patients with dermatomyositis or polymyositis were retrospectively evaluated over a mean of four and a half years. Eighty-five percent (23) met the suggested criteria of Bohan and Peter (New England Journal of Medicine, 1975) for definite or probable disease, while 15 percent had possible disease. Upper and lower limb girdle strength was given a value (0 to 5) and averaged. Initially, 26 percent were severely weak and 59 percent moderately weak. All patients were treated with steroids. Within three months, 64 percent had little to no weakness and no patients were severely impaired. These proportions remained relatively constant throughout the study. Eight less severely ill patients received alternate-day prednisone. Only two still require treatment; the remainder have been in remission for a mean period of 19 months. Of 19 who received daily prednisone, five also required cytotoxic drugs and 11 still require treatment. A comparison of the results of this study with those of major urban referral centers reveals that the patients in this study constituted a generally less ill population with a better prognosis. Forty-one percent (11) of patients were able to discontinue all forms of therapy and remain in remission. Thirty percent (eight) achieved remission with only alternate-day steroid therapy, an approach that has been discouraged in the past. Two patients (7 percent) had overt malignancies within one year before to three years after diagnosis of myositis. However, in no instance did a search for occult malignancy give positive results. Cancer detection was accomplished by following clues from history and physical examinations. It is questioned whether extensive evaluations for occult malignancies in patients with idiopathic myositis are cost-effective.

Using recently developed highly specific antisera to the full range of known adult mammalian skeletal muscle myosins, an immunohistochemical and histochemical examination was made of the middle ear muscle tensor tympani in the dog and cat. Approximately half the fibres were of the IIM type and there was a substantial population of apparently slow-tonic fibres, both these types being rare in mammals. In addition, some type I but no IIA nor IIB fibres were detected. Moreover, as no multiple end-plate innervation, thought to be typical of slow-tonic fibres, could be demonstrated in this muscle by acetylcholinesterase staining or by Ruffini gold impregnation, it is suggested that in tensor tympani the slow-tonic fibres are focally innervated. The very short length of the fibres, only 1-2 mm, is probably sufficient to permit adequate depolarization of a whole fibre by a single centrally situated end-plate. The functional implications of this combination of very rare fibre types in tensor tympani are unclear at present.

In six males with chronic neurological signs who, 14-41 years previously, had an episode of acute trichinellosis cardinal symptoms were chronic muscle pain and lower-neuron damage. Other findings, probably related to trichinellosis, were episodes of pyrexia, chronic gastro-intestinal and cardiac symptoms, and in one case symptomatic epilepsy with psychomotor attacks. Significant laboratory findings were a chronic leukocytosis in one case, repeated elevations of eosinophil count in three. Muscle biopsy in all patients revealed live trichinella and (or) focal myositis. The serological findings did not correlate with the biopsy ones. If the live trichinae are encapsulated, antibody titres may be negative, while they may be markedly elevated when the trichinellae are dead. Whether encapsulated larvae can be influenced by tiabendazol or mebendazol is not clear from these observations.
