    Opis:
    W artykule zaprezentowano wyniki badań szybkości schnięcia wybranych powłok ochronnych. Badaniom poddano powłokę wodną WC-R i alkoholową Zirkofluid 1219. Wyznaczono kinetykę wysychania powłok. Powłoki była nanoszono na rdzenie wykonane z masy o średniej wielkości ziarna osnowy dL= 0,24 mm. Ponadto wyznaczono szybkość wysychania powłok dla trzech ich lepkości umownych (11s; 20s; 30s). Lepkość powłok określono przy pomocy kubka „Forda”. Badania szybkości wysychania powłoki ochronnej prowadzono techniką grawimetryczną. Proces wysychanie mierzono w sposób ciągły. Badania prowadzono w kontrolowanych warunkach: stała temperatura otoczenia, wilgotność powietrza. Stwierdzono, iż czas schnięcia powłoki naniesionej na powierzchnie wypukłe (garby formy) jest dużo krótszy niż powłoki naniesionej na powierzchnie wklęsłe (wnęki). Różnice szybkości wysychania wynikają z odmienności warunków wymiany pary wydzielanej z powłoki do otoczenia.
    Investigation results of the drying rate of the selected protective water coatings are presented in the paper. The water-based coating WC-R and alcohol-based coating Zirkofluid 1219 were subjected to examinations. They were drying kinetics of these coatings. The coating was applied to the cores of the mass matrix with a grain size of dL = 0.24 mm. In addition, the kinetics of the coating drying process was determined for three apparent viscosities: 11s; 20 s; 30 s. The coating viscosity was estimated by means of the Ford 4 mm cup. Drying rates of the protective coating were examined by using the gravimetric technique. Measurements were carried out in a continuous way under controlled conditions: constant ambient temperature and air humidity. It was found that the drying time of a coating applied to the convex surfaces (humps mould) is much shorter than the coating applied to the surfaces of the concave (cavities). Differences in the rate of drying due to differences in the exchange of a vapour of the coating secreted into the surroundings.

    Opis:
    Introduction: Hyperkalemia is a common electrolyte disturbance that occurs within many patients. The more often prevalence of cardiovascular or renal diseases is, the more frequent medical issue hyperkalemia will be. An increasing quantity of entities requires taking medications that affect electrolyte hemostasis. Therefore, reasons for hyperkalemia should be deeply reflected. One of them is pseudohyperkalemia. Purpose: In this study diagnostics and treatment of hypokalemia were presented based on the case report of a 56-year-old man. Case presentation: A 56-year-old man was admitted to the Department of Invasive Cardiology of Medical Hospital of Białystok for complaints of strong chest pain associated with palpitations, cold sweats, feelings of general weakness and anxiety. The patient had no medical history of chronic diseases and neglected to take any medications at length. The laboratory tests performed at admission showed an increased serum concentration of potassium. Through the whole hospitalization, many medications were implicated to overcome hyperkalemia (diuretics, calcium resonium, inhalation with beta2-adrenergic agonists, intravenous infusion of glucose with insulin) with no effect. Hormone test was performed, the results excluded Addison’s or pituitary disease. Differential diagnosis with arterial blood draw showed normal potassium serum concentration. Conclusions: Hyperkalemia is encountered in a broad spectrum of patients. The severely elevated level of potassium could lead to life-threating conditions. Therefore, proper diagnosis making process is a matter of great importance. As clinicians, we need to base not only on laboratory but also examine the whole picture of the patient. Misdiagnosing pseudohyperkalemia might result in unnecessary medical management.

    Opis:
    According to American Obesity Medicine Association obesity is a chronic, relapsing, multifactorial, neurobehavioral disease, wherein an increase in body fat promotes adipose tissue dysfunction and abnormal fat mass physical forces, resulting in adverse metabolic, biomechanical, and psychosocial health consequences. Obesity has been renowned as a risk factor of cardiovascular, endocrinological, orthopedic and many other diseases. But for the last two decades, there have been many reports of beneficial influence of overweight or obesity on patients with coronary heart disease. This phenomenon got a name of obesity paradox. It’s existence is a matter of lively discussion in medical world, and even if true, the protecting mechanisms of obesity need much deeper understanding.

    acute coronary syndrome
    Opis:
    Introduction: Glycoprotein (Gp) IIb/IIIa is a platelet receptor participating in platelet aggregation. According to ESC guidelines, glycoprotein IIb/IIIa inhibitors might be considered during percutaneous coronary interventions in patients with the acute coronary syndrome. Purpose: A case study of profound thrombocytopenia in 80-year-old man with the acute coronary syndrome. Case presentation: An 80-year-old, medicationnaive man with acute coronary syndrome was admitted to the Department of Invasive Cardiology. Due to the unsuccessful invasive strategy, an intracoronary bolus of Gp IIb/IIIa inhibitor – eptifibatide - was administered. During the following intravenous infusion, large subcutaneous hematomas were observed. Eptifibatide infusion was discontinued. Drop in platelet count to 1 thou/μL without significant anemia was registered. A control sample in sodium citrate showed similarly low platelet count - 2 thou/uL. Acetylsalicylic acid and clopidogrel were discontinued, steroids were introduced. Neither PLT nor FFP transfusion were necessary. Consecutive lab tests showed the gradual increase of PLT up to 35 thou/μL at discharge. A week later, the patient did not complain of any cardiovascular or bleeding symptoms; hematomas resented significant involution. Laboratory findings were normal. During follow-up visit 30 days after the discharge, the patient presented no cardiovascular symptoms. Conclusions: There are patients at risk of druginduced thrombocytopenia, especially those with impaired kidney function and the elderly. In such cases, decisions concerning anti-platelet and antithrombotic therapy should be taken cautiously. Because of its rare occurrence, every case of severe thrombocytopenia in ACS patients should be reported. Moreover, such patients should be followed-up to minimalize risk of similar adverse events in the future.
