[The first non-Q myocardial infarct as a clinical manifestationn of acute coronary syndrome].
INTRODUCTION: Non-Q myocardial infarction is only one of the possible clinical manifestations of acute coronary syndromes. Acute coronary syndrome is the most frequent cause of hospitalization in everyday cardiological practice. OBJECTIVES: 1. To evaluate the incidence of unstable angina and myocardial infarction in the group of patients admitted to hospital with diagnosis of acute coronary syndromes; 2. To evaluate the incidence of non-Q myocardial infarction in the group with index myocardial infarction; 3. To determine the frequency of different ECG changes in the subgroup with non-Q myocardial infarction. MATERIAL AND METHODS: The study was conducted at the Institute of Cardiovascular Diseases in Sremska Kamenica in the period between Jan. 1, 1997 and Dec. 31, 1999. Hospitalized patients with acute coronary syndromes (n = 3.337) were divided into subgroups with unstable angina (chest pain, ECG changes and normal level of CK) and with myocardial infarction (chest pain, ECG with/without changes, elevation of cardiac enzymes). Myocardial infarction without Q waves on ECG was considered to be non-Q myocardial infarction. Initial ECG changes (ST elevation, ST depression, inverted T waves, abscence of changes) were evaluated in patients with non-Q myocardial infarction who were not treated with Streptase. RESULTS: During a three-year period, 3.337 patients with acute coronary syndrome were hospitalized. 65.3% of them had unstable angina, while 34.7% suffered from myocardial infarction. In the group with myocardial infarction, 12.9% (280/2179) had reinfarction. 8.8% of patients were treated with thrombolytic agents, which prevented formation of Q waves in 24.6% of patients. In the group of patients who were not treated with thrombolytics, 196 patients (11.8%) fulfilled criteria for non-Q myocardial infarction. Incidence of initial ST elevation, ST depression and inverted T waves in those patients with non-Q myocardial infarction were 11.2%, 35.2% and 52.1% respectively, whereas 1.5% had no ECG changes. CONCLUSION: Both incidence of unstable angina and non-Q myocardial infarction, as manifestations of acute coronary syndromes, and incidence of newly formed ST elevation, which is one of the forms of initial ECG changes in non-Q myocardial infarction, are significantly lower than those found in literature.

Autopsy material analysis at the Cardiology Clinic in 1999.
Clinico-pathological studies serve as a valuable source of information in everyday practice of most medical institutions. The aim of this study was to correlate the clinical and pathological diagnoses of principal disease and cause of death after autopsy in patients who died during 1999 at the Cardiology Clinic, Institute of Cardiovascular Diseases, Sremska Kamenica, Yugoslavia. Medical histories and autopsy reports of dead patients were analyzed: 255 (8.46%) patients died, but only 72 (28%) underwent autopsy. In 53 patients (73%) clinical cause of death was cardiac. Among these patients, consequences of coronary (atherosclerotic) artery disease prevailed in 41 patients (77%). Noncardiac cause of death was established in 19 patients (27%) and vascular causes prevailed with 17 (23%). The comparison of clinical and principal disease established by autopsy revealed a complete concordance in 62 cases, partial concordance in 1 and no concordance in 9 cases. Thus, concordance was found in 86-87.5%. The correlation coefficient was 0.48. Comparison of clinical and autopsy diagnoses of causes of death revealed concordance in 53 patients, with correlation coefficient 0.26.

[The superior vena cava syndrome as a manifestation of dissection of the ascending aorta].
INTRODUCTION: Most clinical manifestations of aortic dissection are due to complications of either ischemic origin or wall rupture of pleural, pericardial, peritoneal or mediastinal cavity. Compression of other blood vessels such as pulmonary artery or superior vena cava is possible, but rarely occurs. CASE REPORT: A 60 year-old patient was admitted to hospital due to severe cyanosis and edema of the face, neck and upper thorax. Ten years ago, due to aortic insufficiency, aortic valve replacement with mechanical prosthesis (St. Jude) was performed. Diagnosis of superior vena cava syndrome was established on the basis of clinical examination, ECG and chest radiography. The etiology was confirmed by echocardiography indicating an enormous dissecting aneurysm of the ascending aorta, 9.2 cm in diameter. Lethal outcome followed 24 h after admission according to the type of electromechanical dissociation. DISCUSSION: The first case of superior vena cava syndrome was described by William Hunter in 1757. This severe disease is caused by tumors which compress or develop inside superior vena cava. In cases of rapid symptom occurrence, thrombosis or compression of vena due to hematoma (trauma, voluminous, dissecting aortic aneurysm) should be considered. Since symptoms of aortic dissection were absent (thoracic pain, aortic regurgitation, pulse asymmetry) the etiologic diagnosis of superior vena cava syndrome was confirmed by echocardiography. Surgical treatment of dissection provides repermeabilization of the superior vena cava and loss of symptoms. CONCLUSION: Superior vena cava syndrome is a rare and slightly known clinical manifestation of ascending aortic dissection. If symptoms rapidly occur, dissection should be considered, particularly in previously surgically treated patients.

[Echotomographic picture of splenic rupture].
Over a period of four years, June 1986-June 1990, we examined 100 patients with semitraumas of the abdomen and the thorax. We sonographically confirmed rupture of the spleen in 12 patients. Sonographic verification of the ruptured spleen can offer direct or indirect sonographic indications. The indirect indication is the liquid in the abdominal cavity (haematoperitoneum). The direct sonographic indication is subcapsular haematoma of the spleen, and heterosonographic indication is the parenchyma in the form of deep unechogenic and liquid fissures of the spleen in all directions. In some patients these unechogenic parts of the spleen converge to the hilus of the spleen.

[Asphyxia and intracranial hemorrhage in high-risk neonates of various gestational ages].
The aim of this study was to compare the type and severeness of brain damage in vitally most endangered newborn infants of different gestational age. We retrospectively analyzed the records of 75 newborn infants treated and decreased at the Department of Intensive Care and Therapy of the Institute of Children's and Adolescents' Health Care in Novi Sad. Diagnoses of hypoxic-ischemic lesion and intracranial hemorrhage in the case of grade four PVH-IVH (periventricular hemorrhage-intraventricular hemorrhage) were established by ultrasonography of the brain and lumbar punction in the case of subarachnoid hemorrhage. These diagnoses were confirmed after forensic-medical expertise. The volume and degree of the damage were compared in regard to the gestational age, Apgar score and time of initial mechanical ventilation and initial parameters of the mechanical ventilation, as well as to values of acido-basic status, concentration of gases in arterialized capillary blood and type of lung damage which always occurred in these patients. In all 75 examined newborns perinatal asphyxia was the dominant etiologic factor for the course and outcome of the disease (in all patients Apgar score was 4 or less). 75% of examines were born before 32 weeks gestation and of low or very low body weight, whereas 72% had intracranial hemorrhage (periventricular-intraventricular) and hypoxic-ischemic damage of the brain parenchyma. The rest of examinees had intracranial hemorrhage or hypoxic-ischemic damage of the brain parenchyma. Although 92% of examinees received mechanical ventilation in the first 3 days of life, only 20% of newborn infants had satisfactory values of acido-basic status and gas concentrations in the blood. We concluded that in the most severe cases of perinatal asphyxia, especially in preterm newborns of low or very low body weight, both intracranial hemorrhage and hypoxic-ischemic encephalopathy develop. Damages of other organs or systems of organs, especially lungs, as a rule contribute to infaust ending.
