The risk of cardiovascular disease in patients with chronic renal disease appears to be far greater than in the general population and the risk of cardiovascular death is much higher than the risk of eventually requiring renal replacement therapy. Heart failure is important finding and it is evident even before the initiation of dialysis; the frequency of heart failure is 10 to 30 times higher in patients on dialysis than in the general population. Left ventricular hypertrophy has incidence of nearly 75-80% and is closely related to heart failure, ventricular arrhythmias, fatal myocardial infarction, aortic root dilatation and cerebrovascular event. ⋯ Patients on dialysis are prone to calcification of media and intima due to disbalance of promoters and inhibitors of calcification process. Now, there are no valid data about the privilege of one dialysis method over another in cardiovascular morbidity and mortality. Numerous traditional and non-traditional risk factors urge for preventive measures for cardiovascular diseases in patients with chronic renal diseases.

Aneurysms of digital arteries are considered to be rarity. They could be true or false. False aneurysms are usually the result of penetrating trauma, while the causes of development of true aneurysms are various, such as blunt trauma, and rarely atherosclerosis, vasculitis and infection. Also, they can be idiopathic. Reviewing the literature we found 13 cases of previously described true aneurysms of digital arteries. None of them referred to the common digital artery aneurysm. ⋯ As mentioned above, true aneurysms of digital arteries are very rare, so they are of little clinical importance. The most common symptom of digital artery aneurysms is pain, with a tender pulsatile mass on examination. Since natural healing cannot be expected, surgical treatment of true digital artery aneurysms is recomended for pain relief and avoidance of complications which may occur and are related to the aneurysm presence. Aneurysm resection and ligation of a blood vessel can be performed. Also, artery reconstruction can be performed by primary end-to-end anastomosis or the placement of a reversed interposition vein graft.

Mortality in ST elevation myocardial infarction (STEMI) ranges from 4-24% and is dependent on the variety of patients' clinical characteristics (CC) that are present prior to and within the first hours of the onset of MI, affecting reliability of the diagnosis. The higher mortality rate of patients with STEMI should be associated with a higher rate of applied reperfusion therapy according to guidelines and randomized study results, which is in opposition to everyday hospital practice. ⋯ Clinical characteristics significantly influence mortality in STEMI; a significantly higher mortality is among women, patients in their 80's and 90's, anterior MI localization and prior coronary disease. RT significantly lowers mortality in STEMI compared to the use of classical therapeutic approach and therefore STEMI patients with a higher mortality determined by their prehospital charactheristics, i.e. higher risk, are those who have higher benefit of RT, which should be taken into consideration when making decision about the therapy of choice.

Despite numerous advances in medicine, the mortality rate of severe sepsis and septic shock remains high, 30-50%. New therapy strategies include: early goal-directed therapy, fluid replacement, early and appropriate antimicrobials, source of infection control, use of corticosteroids, vasopressors and inotropic therapy, use of recombinant activated protein C, tight glucose control, low-tidal-volume mechanical ventilation. They have been shown to improve the outcomes. The adequacy and speed of treatment influence the outcome, too. ⋯ Evidence-based clinical guidelines for management of severe sepsis and septic shock have not been implemented in a widespread, systematic way in the ICU of the Clinical Centre, Kragujevac. Institutional acceptance of this protocol, and education of clinicians may improve survivability for patients with sepsis.

C-reactive protein (CRP) is the most common diagnostic marker of infection. ⋯ CRP levels are proportional with increasing GA and body weight in EOS. The effects of gestational age do not influence CRP levels in LOS. Maturation changes in the immune system are the most likely explanation for this and partly the organisms responsible for an infection may be different at different gestational ages and also in EOS and LOS. There is no correlation with serum CRP levels and with the severity of the disease and bad prognosis in EOS.
