Data are presented on the differential diagnosis of some forms of the ischaemic heart disease, myocardial infarction including, performed with the help of a long--distance enquiry of the "Nairi-K" computer. This is one of the adjunct methods of early and timely diagnosis of myocardial infarction that permits to differentiate it from angina pectoris, postinfarction cardiosclerosis, acute abdominal pathology, pleuropneumonia, and to determine the localization of the necrosis. The exactness of the diagnosis ranges from 93 to 95%. An information system was developed that permits a more objective assessment of the nature of the ECG changes.

An enzyme-linked immunosorbent assay (ELISA) test using polyvalent antigens and antisera was developed to detect Coxsackie-B-virus-specific IgM responses. The sera of 24 of 64 (37.5%) patients with acute pericarditis and 14 of 38 (36%) with acute myocarditis were positive for Coxsackie-B-virus-specific IgM. 4 of 30 (13.3%) patients with acute ischaemic heart disease and 2 of 28 (7.1%) patients with congestive cardiomyopathy were also positive. Coxsackie-B-virus-specific IgM was detected in the sera of 21 of 57 (36.8%) patients with Bornholm disease and 2 of 4 patients with acute-onset juvenile diabetes. Coxsackie-B-virus-specific IgM responses persisted for 6-8 weeks. Sera from patients with chronic valvular heart disease, Mycoplasma pneumoniae infections, and virus infections caused by viruses other than Coxsackie-B viruses were all negative. False-positive results did not occur when sera containing high titres of rheumatoid factor were tested.

The role of infectious and inflammatory causes of stroke is much more significant in children than in adults. Conversely, that of atherosclerotic disease, ischaemic heart disease and hypertensive haemorrhages has a lesser prominence in children. Bacterial meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae, or Neiserria meningitidis has been known to cause stroke in children. The mechanism appears to be the spread of meningeal inflammation to involve the walls of intracranial vessels, resulting in arterial thrombosis with ischaemia or rupture with haemorrhage. Other infections caused by atypical bacterial agents such as Mycoplasma tuberculosis and viral agents such as varicella-zoster virus have also been well documented as causes of stroke. Non-infectious, inflammatory causes of stroke, such as collagen vascular disease and primary angiitis of the central nervous system, have been reported in children as well as adults. In this review, we will focus on recent advances in the field of childhood stroke caused by infectious and inflammatory disorders.

The study enrolled 53 patients (29 males, 24 females) with respiratory mycoplasmosis aged 15-88 years. Most of them were 59 years of age and younger. In 1/3 of the patients the diseases started with symptoms of acute respiratory viral infection, in 2/3 of them--with pulmonary affection. Pneumonia was diagnosed in 50 patients (94.3%), acute bronchitis--in 3 patients. ECG changes were registered in about half of the examinees who had no cardiac complaints. 25 of them had alterations in the end part of the ventricular ECG complex; rhythm and conduction disturbances occurred rarely. Mycoplasmosis patients suffering from ischemic heart disease (IHD) had stable ECG changes while in those free of IHD the changes were short. Myocardial necrosis foci were absent. Cardiac damage comparison in patients with respiratory mycoplasmosis and in other acute respiratory infections has found that cardiovascular system suffers less in acute mycoplasmosis. These data are useful in differential diagnosis of myocardial infections.
