The silicone gel breast implant controversy: current status and clinical implications.

The silicone breast implant controversy has amassed a great deal of media coverage in the past year. Unfortunately, separating fact from fiction has been extremely frustrating and difficult, not only for physicians but for women who have either had or are considering cosmetic or reconstructive surgery of the breast. At a recent meeting attended by most of the board eligible and certified Plastic and Reconstructive Surgeons in the State of Arkansas, it was felt that a consensus statement was needed to clarify the issues and inform other Arkansas physicians of the most up to date information. The result is a fairly comprehensive review which will require your indulgence. Breast implants are placed not only by Plastic and Reconstructive Surgeons, but by Otolaryngologists, "Facial Plastic Surgeons", Obstetricians/Gynecologists, General Surgeons, Dermatologists and Family Practitioners. We believe it is the ethical and legal responsibility of the physicians who elect to perform these procedures to provide adequate care and follow-up for these patients when either real or perceived problems arise. Accurate information, reassurance and occasionally re-operations are required for many of these patients.

Pulmonary angiography in a non-teaching hospital over a 12-year period.

OBJECTIVE: To report the safety of pulmonary angiography in a non-teaching hospital and discuss the place of this investigation in the diagnosis of pulmonary embolism. DESIGN AND SETTING: A retrospective review of all patients undergoing pulmonary angiography over a 12-year period, November 1979 to October 1991, at Dandenong Hospital, Melbourne. A protocol was established whereby each procedure was performed with the assistance of staff and equipment from the intensive care unit to provide haemodynamic monitoring and measurement of pulmonary artery pressures. PATIENTS: During the review period 114 patients underwent pulmonary angiography, most (108) for suspected pulmonary embolism. RESULTS: One hundred and fifteen pulmonary angiograms were performed, and no deaths related to the procedure occurred. Complications included perforation of the right atrium in three patients, with no sequelae. Cardiac arrhythmias were common but self-limiting. CONCLUSION: In our series, pulmonary angiography was a safe procedure if undertaken with the appropriate monitoring measures. A protocol which includes the participation of the intensive care unit has proved helpful. In addition, it was found that clinical symptoms and signs were unreliable and in 24 patients who also had ventilation-perfusion (V/Q) scans, only seven scans were accurate. A review of the literature indicates that V/Q scans lack specificity and that pulmonary angiography may be performed safely. The latter investigation should be more frequently performed.

Hexabrix 320R for C.T. (computed tomography)--patient tolerance and image quality.

A total of 367 patients were studied using Hexabrix 320 as intravenous contrast material during CT scanning. Adverse events were recorded and analysed with respect to patient age and risk category. Hexabrix 320 produced adequate image quality in all patients. Whilst minor adverse events were relatively common, only a few moderate adverse events were seen and no severe adverse events were observed. Hexabrix 320 was noted to be very well tolerated in the elderly and well tolerated by the high risk patient.

Angiocardiography and exercise testing at one month after a first myocardial infarction.

The results of exercise testing (77 patients), left ventriculography and coronary arteriography (78 patients) are presented for men under the age of 60, one month after a first myocardial infarct. Cineangiocardiography revealed that patients with anterior infarction (n = 25) had both poorer left ventricular function and more totally occluded vessels than those with either inferior (n = 33) or subendocardial infarction (n = 20). In contrast, patients with inferior and subendocardial infarction had a greater proportion of myocardium supplied by sub-total lesions likely to be haemodynamically significant (75%-99% cross sectional area loss). Subendocardial infarction was also characterised by the best left ventricular function and the fewest number of total coronary occlusions. Stress testing showed that the combination of ischaemic ST segment changes and angina during exercise was 91% predictive of severe coronary disease (equivalent to triple vessel disease) while no angina in the presence of a negative test was 81% predictive of mild or moderate disease. Stenoses of 75%-99% cross sectional area loss were more common when angina occurred during exercise testing, and both angina and ischaemic ST segment changes occurred within ten minutes in all four patients with haemodynamically significant left main coronary artery lesions. Our data supports the usefulness of exercise testing after a first myocardial infarct and may provide valuable baseline information in the analysis of long term prognosis.

Comparison of enzymic with cineangiocardiographic estimations of myocardial infarct size.

Comparisons were made between enzymic indices of myocardial infarct size (total creatine kinase appearance and peak enzyme activity) measured during the acute state of a first myocardial infarct in 32 male patients, and analysis of contraction abnormalities in biplane left ventricular cineangiocardiograms performed one month later. The cineangiocardiograms were analysed independently by two radiologists, each using two different methods for quantification of subjectively classified abnormalities of left ventricular wall motion. A very strong correlation was found between the two enzymic indices of infarct size and somewhat weaker correlations between assessment of contractility abnormalities made by the two radiologists using the same method, or by the same radiologist using the two different methods. Comparisons between enzymic and angiocardiographic indices for all infarcts showed correlation coefficients (r) within the range of 0.53 to 0.72. With all comparisons of enzymic with radiological indices r values were higher for anterior infarcts than for inferior infarcts, and there was a tendency for higher enzyme levels for a given degree of left ventricular damage in inferior than in anterior infarction. This may be the result of variable degrees of right ventricular damage in inferior infarction.

The diagnosis of right ventricular perforation by an endocardial pacemaker electrode.

The diagnosis of right ventricular perforation by an endocardial pacemaker electrode should be suspected when failure of pacing occurs without electrode displacement. Although a number of changes occur on the standard electrocardiogram (ECG), none of these are diagnostic. The intracardiac electrogram performed during electrode withdrawal is not only diagnostic of perforation but can also aid in electrode positioning. Two case reports highlight these changes in the intracardiac electrogram. The first case also illustrates that, with electrode perforation, the ability to sense the intrinsic intracardiac electrical activity may be retained.
