[A novel method of conservative therapy of infected dental root canal by means of chlorhexidine and corticoids].

The treatment of the acute phase within the therapy of the infected root canal is possible using a combination the antiphlogisticum Triamcinolon and the disinfectant chlorhexidine. The medical agent TS 74 (Forapical) was used in 82 teeth of acute or acute exacerbated chronical periodontitis. Successful conservative treatment was observed in 90% of all cases.

The development of symptomatology and functional condition in patients with negative or minimal findings on coronary vessels after 5 to 10 years.

The authors compared two groups of men: the group with minimal sclerotic wall changes (n = 18) and the group with a normal coronary angiographic finding (n = 32). All the examinations were repeated after 5 to 10 years (mean 8.4 years). The two groups did not differ in the occurrence of the main IHD risk factors, complaints, kind and amount of principal drugs and working history. No statistically significant differences were found between the groups in the reasons for discontinuing bicycle ergometric test or in the exercise ECG finding. The two groups studied did not differ in the mean values of limiting metabolic and cardiologic parameters (oxygen consumption, lactate, pulse rate, RPP index) either. The conclusion can be made that in the functional and clinical prognosis the group of symptomatic men with minor sclerotic wall changes does not differ practically from individuals with completely normal coronary angiography.

[Cardiac tamponade as a complication of acute myocardial infarct. (Clinical and pathologico-anatomic analysis of patients with acute myocardial infarct and cardiac tamponade)].

Cardiac tamponade is a frequent cause of death in acute myocardial infarction--in as many 23%. It is encountered in particular in the 7th and 8th decade, in patients with a first infarction which is frequently situated in the anterior wall of the left ventricle. 93% of the patients have obvious ECG manifestations of Q infarction. The diagnosis of cardiac tamponade is easy when during an acute terminal attack slow activity on the ECG tracing is found without a haemodynamic response and the pulse on the great arteries is not palpable even after external cardiac massage. In 80% the onset of cardiac tamponade is very sudden. The presence of shock or cardiac failure makes the diagnosis of cardiac tamponade more difficult. As to investigated indicators, in the development of cardiac tamponade the systemic pressure--systolic as well as diastolic--on admission or during hospitalization, may play a part. The patients have a less marked coronary sclerosis, fibrosis of the cardiac muscle is less frequently present. Previous necroses of the heart muscle may have probably a certain protective effect on the development of cardiac tamponade. Anticoagulants obviously do not influence the development of cardiac tamponade.

Assessing dose equivalent from intensive short-term U product inhalation.

Intensive exposure of a product packaging operator to U product dust resulted in the uncontrolled inhalation of natural U. In-vivo counting yielded an estimate of about 40 mg of natural U initially deposited in the lung. An effective committed dose equivalent in the range of 67 mSv and 137 mSv was calculated to correspond to this lung contamination, using a single exponential lung clearance and the modified ICRP models, respectively. The effective committed dose equivalent of a person 47 y old involved in this incident can hardly be used to quantify the risk, and therefore committed and annual dose equivalent systems were discussed in light of risk assessment.

Left ventricular response to sublingual administration of nitroglycerin.

The aim of this study was to investigate whether the rapid improvement of the clinical condition of patients after administration of nitroglycerin can be documented objectively using the apexcardiogram. The study was performed on 28 male patients with coronary heart disease whose clinical condition allowed us to perform the initial polygraphic examination during an attack of angina pectoris. The heart rate and three apexcardiographic indexes were determined from non-invasive polygraphic tracings. The first index was the a/H (ratio: amplitude of apexcardiographic "a" wave to total amplitude of apexcardiogram). The second and third were the velocity of the anterior left ventricular wall motion during both isovolumic contraction (VwmC) and isovolumic relaxation (VwmR) of the left ventricle. The mean differences from initial values were calculated after 2, 4, 6 and 10 min following administration of nitroglycerin. Significant changes already occurred during the second minute after administration of nitroglycerin. All parameters remained significantly changed up to the 10th minute after this treatment. According to our results, the cardiovascular response to sublingual administration of nitroglycerin can be objectively evaluated by apexcardiography.
