[ECG in patients with hemorrhagic fever]. / EKG u bolesnika sa hemoragicnom groznicom.

We analyzed 128 electrocardiograms (ECG) of 43 patients with haemorrhagic fever associated with kidney syndrome (HFKS) during an epidemic in 1989, region around Sarajevo. The greatest number of alternations was noticed in toxic phase, and the smallest number in invasive phase of disease. All alternations were transient. Extended QT interval was dominant, and was found in 19 patients (45%). Tall and peaked T wave in the case of 17 patients or in 40%, during toxic and recovering phase, was the second by its frequency. As the third by its frequency, there was U wave manifestation. We found this kind of alternation in the case of 13 patients or in 31%. Incomplete right bundle branch block was the most frequent find during invasive phase of HTKS and it was found in 3/7 of all patients. The same thing was found in 6 patients more, during toxic phase, so in total it was 21%. First degree AV block was presented in 8 patients or 19%. Other finds, ischemia, P-pulmo, arrhythmia etc. had frequency less than 10%.

[Acute viral hepatitis--present status and perspectives]. / Akutni virusni hepatitisi--sadasnje stanje i perspektive.

Recent advances in epidemiology, virology, of clinical of hepatitis are presented in the paper. The authors pointed out that hepatitis A never becomes chronic. On the other hand, with hepatitis B or B and D, evolution to chronicity is possible. Two distinct forms of non-A non-B hepatitis are now distinguished: parenterally transmitted non-A non-B hepatitis, mainly due to hepatitis C virus; enterically transmitted non-A non-B hepatitis mainly due to hepatitis E virus. C virus hepatitis is characterized by a frequent course to chronic hepatitis, cirrhosis and hepatocellular carcinoma. Chronic forms are associated with the presence of anti-HC antibodies in the serum. These antibodies are rarely present in the acute stage of the disease. Hepatitis E is almost exclusively encountered in developing countries. Like with A virus hepatitis, chronicity never occurs. However, fulminant hepatitis is possible in pregnant women in the third trimester of pregnancy. There is no routine serological test. Development of vaccines against A, E and C viruses can be expected very soon. There is no specific treatment of acute viral hepatitis.

[C-reactive protein values]. / Vrijednost C-reaktivnog proteina.

According to our research, C-reactive protein is powerful separator between bacterial and viral infections. For this case the best discriminative value is 40 mg/l. A more serious bacterial infections are usually followed by a higher concentration of CRP in serum, but its serial determination presents truly the improvement of bacterial infect, otherwise it is happening spontaneously or under the influence of adequate therapeutica.
