Global use of electronic nicotine delivery systems (ENDS; also called electronic cigarettes, e-cigarettes) has increased dramatically in recent years. However, due to the limited safety studies and growing concerns on the potential toxicity from long term use of ENDS, many national and international governments have employed regulatory measures to curtail its use. One of the most significant challenges regulators of ENDS encounter is the lack of quality standards to assess ENDS, e-liquid (solution used with ENDS which contain nicotine--a highly toxic and addictive substance), and amount of nicotine delivery to aerosol during ENDS use. ⋯ Our analysis showed the high consistency between the labeled and measured nicotine concentration for popular on the Polish market ENDS e-liquids. Also, our analysis demonstrates that the risk for nicotine overdose is likely minimal when ENDS are used in a similar manner as a combustible cigarette. However, due to the toxicity risk nicotine poses regulatory measures focused on safety and quality of e-liquids should continually be exercised.

Randomized Controlled Trial Observational Study
[Assessment of chronic glucose metabolism disorders coexisting with respiratory failure in non-critical ill patients hospitalized with lower respiratory tract infections].
Lungs are the target organ in chronic hyperglycemia, but its large reserves causes a subclinical course of these changes. Given the results of other researchers indicating reduced active surface of gas exchange and pulmonary capillary damage, it can be assumed that diabetes and other hyperglycemic states diminish these reserves and impair effectiveness of respiratory gas exchange during pneumonia. So it is plausible to observe coexistence of glucose metabolism disorders and respiratory failure in patients hospitalized with lower respiratory tract infection. ⋯ There was a statistically significant negative correlation of the average blood glucose level and PaO2 in the control group (p = 0.0152) and a significant inverse association between the average blood glucose level and the partial pressure of oxygen in patients without COPD belonging to the control group (p = 0.049). Respiratory failure is frequent in patients hospitalized with pneumonia. In patients without chronic glucose metabolism disorders with blood glucose level rising the oxygen tension decreases The association is stronger in patients without COPD.

Erythema exudativum multiforme (EM) is an acute mucocutaneous disease. Etiology of this disease is not clear. 50% - 60% cases of EM is induced by HSV infection (herpes simplex virus 1, herpes simplex virus 2). EM lesions may appear as red macules, erosions, ulcerations and hemorrhagic crusts. The study describes the case of 22 - year - old male who had characteristic lesions for EM after HSV infection.

Cigarette smoke is the major and most common indoor source of carbon monoxide. CO combines with haemoglobin to form carboxyhaemoglobin (COHb) which hinders oxygen transport and causes myocardial infarction and coronary heart disease. CO damages the endothelium of large and medium arteries and contributes to the development of atherosclerosis. ⋯ For non-smokers, the study identified a significant relationship between the level of exhaled CO and the participants' gender (p < 0.05), weight (p = 0.003), and height (p = 0.0005). For smokers, there is a relationship between the level of eCO and the daily cigarette consumption (p = 0.01), the type of cigarettes most frequently smoked (p < 0.05) and the favoured cigarette brand (p = 0.005).

The consumption of energy beverages is increasing, especially among young people. The increasing consumption of these drinks increases the data of side effects. Case report: A 26-year old male was admitted to Toxicology Department suspected of intoxication due to ethyl alcohol and unknown psychoactive substances. ⋯ Unfortunately, serum caffeine levels were not measured. There was no identification of any other factors that could be responsible for the observed symptoms. It appears that based on the interview, clinical manifestation, and negative toxicology laboratory testing (excluding the presence of ethanol), it is possible to connect the seizure state with the consumption of a high dose of energy drinks, rich in caffeine and taurine.
