Chronic skin exposure to a wet work environment, as well as disinfectants are factors contributing to epidermal barrier damage. This disturbs its protective functions and promotes the development of dermatoses. All these factors occur in the work environment of a laboratory diagnostician. The aim of the paper was to analyze selected skin parameters and skin lesions in the hands of laboratory diagnosticians.

Overall, 50 laboratory diagnosticians employed in a laboratory in Kraków, Poland, took part in the study. After the interview, the skin pH and moisture content were examined. Measurements were performed on the dorsal side of the dominant hand using the Skin-ph-Meter^® PH 905 and Corneometer^® CM 825 devices.

The obtained moisture level values were qualified as dry or very dry skin, and the skin pH was within the reference range. No correlation between the skin pH value and the features examined (professional experience, the number of hours spent in protective gloves during the day, the number of hand washing episodes during the day) was not indicated. The level of skin moisture content seems to positively correlate with the time of wearing gloves. The use of hand moisturizers after each hand washing episode correlated with the level of skin moisture content.

Appeals to stop the usage of disposable drinking straws or plastic cutlery did not come out without reason - 320 million tons of plastic products are produced annually, of which 40% are disposable items. More and more countries and private enterprises are giving up these types of items in favor of their biodegradable substitutes, e.g., cardboard drinking straws. Plastic waste in the environment is subject to a number of physicochemical interactions and biodegradation in which bacteria are involved. By using synthetic waste, they reduce the size of plastic garbage while increasing its dispersion in the environment. Small plastic particles, invisible to the naked eye, are called nanoplastic. Nanoplastic is not inert to living organisms. Due to its size, it is taken up with food by animals and passed on in the trophic chain. The ability to penetrate the body's barriers through nanoplastic leads to the induction of biological effects with various outcomes. Research studies on the interaction of nanoplastic with living organisms are carried out in many laboratories; however, their number is still a drop in the ocean of the data needed to draw clear-cut conclusions about the impact of nanoplastic on living organisms. There is also no data on the direct exposure to nanoplastic contamination at workplaces, schools and public utilities, standards describing the acceptable concentration of nanoplastic in food products and drinking water, and tests on nanoparticles other than polystyrene nanoparticles. Complementing the existing data will allow assessing the risks arising from the exposure of organisms to nanoplastic.

This nosological entity is relatively uncommon, however its importance for modern medicine should not be underestimated. Despite a low incidence of the pathology, it should be understood that the disease's course for the patient is associated with the development of severe complications which may lead to disability or even death. The development of complications is extremely difficult to predict and stratification of risks for such patients is too complicated. It is also known that the diagnosis of a subclavian artery aneurysm is frequently an accidental finding, since the pathology may for a long time proceed symptom-free. At the same time, the subclavian artery occupies the first place by the frequency of localization of upper-limb aneurysms, thus making this problem currently important. Besides, separate attention should be paid to modern methods of correction of this disease, since implementation of high-tech interventions into vascular surgery have significantly expanded the arsenal of the operating surgeon.Acute coronary syndrome has for a long time been giving no way of decreasing mortality related to ischaemic heart disease. The primary cause of acute coronary syndrome in the majority of cases is rupture of an unstable atherosclerotic plaque in the coronary artery followed by thrombosis thereof. The main missions of modern cardiology include assessment of the risk of acute coronary syndrome, identification of predictors of adverse events, and working-out of measures aimed at prevention and optimal management of patients with ischaemic heart disease. This article deals with clinical and morphological factors associated with destabilization of coronary plaques, their rupture, and the development of an acute coronary event.Presented herein is a clinical case report regarding a repeat intervention for a type II dissecting thoracoabdominal aortic aneurysm treated by means of a hybrid technique in a 76-year-old male patient with a single kidney, having 9 years previously endured resection of an aneurysm of the infrarenal aortic portion. The first stage consisted in prosthetic repair of the thoracoabdominal aortic aneurysm by an oblique anastomosis, with the second stage (7 days thereafter) being endoprosthetic repair of the descending thoracic aorta. The findings of check-up computed tomography at 16 months postoperatively demonstrated no negative dynamics.Extracranial carotid artery aneurysms belong to uncommon and dangerous vascular diseases. Reported herein are the results of successive surgical treatment of a patient presenting with an extracranial aneurysm of the internal carotid artery. Given anatomical peculiarities (large dimensions of the aneurysm, tortuosity of the internal carotid artery), it was decided to perform resection of the aneurysm with an end-to-end anastomosis established. The patient examined at 12 months postoperatively was found to be free from the syncopal states, with no restenosis of the zone of the anastomosis revealed. The chosen therapeutic policy provided effective prevention from the development of ischaemic stroke and aneurysmal rupture, as well as improved the patient's quality of life. An open reconstructive operation is an optimal method of treatment of patients presenting with extracranial carotid artery aneurysms.
