This paper presents the findings on two patients with a final diagnosis of dermatomyositis in whom 111In-antimyosin imaging revealed diffuse muscle necrosis of the limbs. The potential application of this scintigraphic procedure for diagnosis and follow-up of patients with dermatomyositis-polymyositis is addressed.

Radionuclide assessment of right ventricular regional wall motion abnormalities in anterior left ventricular infarction.

Because of its potential use in the detection of right ventricular myocardial infarction, we performed radionuclide ventriculography in 80 consecutive cases of electrocardiographically anterior acute MI. Regional wall motion of both ventricles was studied on amplitude-phase images. Forty-five patients (56%) showed normal right ventricular function and 35 (44%) regional right ventricular dyskinesia: 19 in the septal, 14 in the apical and 2 in the free wall region. Right ventricular septal, respectively apical asynergy were virtually always associated with asynergy in the homologous parts of the left ventricle. This could be a consequence of the proximity of these regions, or alternatively be due to a common vascular supply. Thus it remains uncertain if asynergy in these regions signifies necrosis of part of the right ventricular wall. Free wall asynergy was considered as evidence of right ventricular wall necrosis. Thus, in our study group the prevalence of right ventricular myocardial infarction in anterior left ventricular myocardial infarction was at least 2.5%.

Cervicofacial actinomycosis in a patient treated for tonsillar carcinoma.

A 50-year-old patient who underwent locoregional radiotherapy and surgery for a tonsillar carcinoma, developed osteomyelitis with Actinomyces israelii with fistulization in the treated area, during chemotherapy treatment. This rare complication is discussed.

Effect of DC-shocks of 400 Joules on the AV-node.

Ablation of the AV-node with direct current shocks and 6-French U.S.C.I. catheters was performed in 8 patients with disabling supraventricular arrhythmias. An initial shock of 400 Joules was chosen in most instances. In all patients transient or permanent complete AV-block was obtained. For one patient the procedure was considered a failure, after three sessions. Five patients remain in complete AV-block. Average escape rhythm at first ambulatory follow-up was 47 bpm. The block seems to be situated at the level of the bundle of His, or distal of this level. The other two patients are clinically improved with impaired AV-conduction. A pacemaker was implanted in all patients.

Vanishing "ureterohydronephrosis" on technetium-99m-MDP bone scanning.

Finding a marked bilateral renal and ureteral activity on a bone scan has been regarded as being highly specific for bilateral ureterohydronephrosis. We report here on a patient in whom this finding was not confirmed by repeated bone scanning and in whom subsequent radiologic and ultrasound examination proved normal. The possible mechanisms involved in this vanishing "ureterohydronephrosis" are discussed.
