[Our subcostal retractor].

A new self-restraining table-fixed abdominal retractor, thought up and built by Dr. Bonini, is described. This retractor is easy to construct and use and is recommended whenever very good exposure of the diaphragmatic vault and the supramesocolic area is required.

Diagnosis of acute myocardial infarction by indium-111 antimyosin antibodies and correlation with the traditional techniques for the evaluation of extent and localization.

This clinical study evaluated the accuracy of planar myocardial scintigraphy with antimyosin monoclonal antibodies radiolabeled with indium-111 (AMA-Fab) in the detection and localization of acute myocardial infarction (AMI). Fifty-seven patients admitted for suspected AMI were studied; 17 patients underwent thrombolytic therapy with intravenous streptokinase and 11 had clinical signs of reperfusion; 9 had had a previous myocardial infarction. Fifty of 57 patients were discharged from the coronary care unit with a confirmed diagnosis of AMI. The AMA-Fab study results were positive for AMI in 49 patients (98%) and negative in 1 (2%). Among the 7 patients without AMI, 5 had unstable angina, 1 had Prinzmetal's variant angina and 1 had acute pancreatitis. AMA-Fab results were negative in 6 of 7 patients (85%) and positive in 1 (15%). Therefore, the sensitivity and specificity of AMA-Fab scintigraphy were 0.98 and 0.85, respectively. To assess accuracy in defining the extent and location of AMI, AMA-Fab results were compared with those of the electrocardiogram, echocardiogram, technetium-99m pyrophosphate myocardial scintigraphy and coronary angiography and left ventriculography. AMA-Fab scintigraphy showed a good concordance with the traditional techniques in the topographic definition of the infarcted regions. No uptake of AMA-Fab was seen in the regions of previous old infarcts. Ten healthy volunteers also underwent AMA-Fab scintigraphy. No evidence of myocardial tracer uptake was noted in them. No adverse reactions or side effects were noted after injection of AMA-Fab in any patient. It is concluded that planar myocardial scintigraphy with AMA-Fab is a reliable method for AMI detection and location.

New tracers for the imaging of the medullary thyroid carcinoma.

I-MIBG and 99Tcm(V)-DMSA have been recently proposed as scintigraphic markers of the medullary thyroid carcinoma (MTC). Thirty two patients were examined with 131I- or 123I-MIBG and 26 of these were re-examined with 99Tcm(V)-DMSA (planar and SPECT). From our experience we can draw the following conclusions: (1) the scintigraphic attempt was useless in patients with normal levels of plasma calcitonin (CT): (2) in patients with high plasma CT levels, the sensitivity of the MIBG was better in familiar (3/3 true positive) than in sporadic disease (7/21 true positive; overall sensitivity = 42%); the 99Tcm(V)-DMSA was positive in 16/19 cases, (overall sensitivity = 84%) even in cases which had been false negative with MIBG (6 patients); (3) no false positive results were found; (4) the scan with 99Tcm(V)-DMSA is then suggested as the first imaging approach during the follow up in patients affected by MTC and still having high levels of plasma CT. The MIBG scan should be limited to the patients in whom the possible use of MIBG therapy has to be investigated.

[Incidence and clinical significance of involvement of the right ventricle in acute inferior myocardial infarction].

UNLABELLED: The purpose of our study was to evaluate, with noninvasive procedures, the incidence and the clinical picture of right ventricular involvement in patients with acute transmural inferior myocardial infarction. Our study group was constituted of 107 consecutive patients admitted to our Coronary Care Unit within 10 hours from the onset of symptoms; in every patient a standard 12-leads ECG and the precordial leads V3R and V4R were obtained at admission in CCU and then every 12 hours. 80 patients underwent B-mode echocardiographic evaluation within 36 hours and in 93 patients a myocardial scintigraphy was performed, between the 48th and 72nd hour from the onset of chest pain, 1-2 hours after injection of Tc-99m-pyrophosphate. RESULTS: 45 patients (42.1%) had ECG positive for right ventricular infarction, 49 patients (51.6%) had positive Tc-99m-pyrophosphate scintigraphy and 24 patients (30%) positive echocardiography. By using the positivity of ECG and another method at least, patients were separated into 2 groups: group A (associated inferior and right infarction) was constituted of 45 patients, and group B (isolated inferior infarction) was constituted of 62 patients. In group A we noted a higher incidence of hypotension (systolic blood pressure less than 100 mmHg) and oliguria (less than 30 ml/h)- p less than 0.01-, of 2nd and 3rd A-V blocks-p less than 0.001- and primary ventricular fibrillation -p less than 0.01. The incidence of parossistic atrial fibrillation, severe bradycardia or SA blocks and of mortality was not statistically different between the two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Body composition and nutritional status in patients on continuous ambulatory peritoneal dialysis (CAPD).

Total body water (TBW), extracellular water (ECW), exchangeable potassium pool (EKP), and alkali-soluble nitrogen in skeletal muscle tissue (N) were determined in 9 CAPD patients on treatment from 5 to 14 months (mean 8.6 months). The parameters were reevaluated in 6 of these patients 5 to 13 months later (mean 8.6 months). The mean value of TBW was normal and directly correlated to body weight (BW), but TBW was abnormally distributed between extracellular and intracellular space. ECW volume was significantly lower than the predicted value (12.1 +/- 1.4 versus 16.8 +/- 1.9 l) and out of proportion to TBW (34.8 +/- 3.9% versus 47.8 +/- 1.5%). The calculated intracellular water, therefore, appeared clearly hyperexpanded. The mean value of EKP was slightly reduced, but in three patients there was a 25% reduction. N content was low in 5 out of 9 patients. When the parameters were re-evaluated BW and TBW were unchanged in two subjects. A third patient showed a simultaneous increase in both BW (12.7%) and TBW (19%). TBW variations (+19%, -23%, -24%) without changes in BW were seen in three patients. The mean value of EKP was unchanged, but there was a 25% reduction in one patient. N content improved in two and worsened in one of the three patients in whom it was determined. The data suggest that cell overhydration was the distinctive feature in our CAPD patients, and that the evolution of the nutritional status was variable, since the patients could remain stable, gain or loose body fat, and probably change their lean body mass.

[Carcinoid of the gastrointestinal system (study of a clinical case)].

The authors describe a case of multiple carcinoid tumours of stomach, which arose on an atrophic chronic gastritis. The case was studied in strict equipe cooperation by physicians, surgeons, radiologists, anatomopathologists, and, subsequently, it was surgically treated through total extended gastrectomy.

Body fluid spaces in patients on CAPD.

Total body water (TBW) and extracellular water (ECW) were determined in 9 CAPD patients on treatment from 5 to 14 months (mean 8.6 months). The mean value of TBW was normal and directly correlated to body weight, but TBW was abnormally distributed between extracellular and intracellular space. ECW volume was significantly lower than the predicted value (12.1 +/- 1.4 l versus 16.8 +/- 1.9 l) and out of proportion to TBW (34.8 +/- 3.9% versus 47.8 +/- 1.5%). The calculated ICW, therefore, appeared clearly hyperexpanded. The data suggest that cell overhydration was the distinctive feature in our CAPD patients.
