The radioactivity of some structural building materials, rows, binders, and final construction products, originating from Serbia or imported from other countries, was investigated in the current study by using the standard HPGe gamma spectrometry. The absorbed dose in the air was computed by the method of buildup factors for models of the room with the walls of concrete, gas-concrete, brick and stone. Using the conversion coefficients obtained by interpolation of the International Commission on Radiobiological Protection (ICRP) equivalent doses for isotropic irradiation, the corresponding average indoor effective dose from the radiation of building materials of 0.24 mSv·y−1 was determined. The outdoor dose of 0.047 mSv·y−1 was estimated on the basis of values of the specific absorbed dose rates calculated for the radiation of the series of 238U, 232Th and 40K from the ground and covering materials. The literature values of the effective dose conversion coefficients for ground geometry were applied as well as the published data for content of the radionuclides in the soil.

Today sclerotherapy is the elective treatment for most cases of telangiectases. The main exceptions are "red" telangiectases, those with a caliber <0.3 mm and those with high flow, which do not respond to sclerotherapy or are aggravated by it as they require high concentrations of locally and generally toxic sclerosant solutions.The aim of the study was to remove all types of telangiectases, reduce doses and concentrations of sclerosant drugs, reduce risks and side effects, improve course and recovery time and increase long-term effects.Material and methods. We treated the types of telangiectases above-mentioned (563 cases on the legs, 375 on the face) with laser photocoagulation and two different techniques, called Laser-Video Sclerotherapy (LVST) and Laser-Video Therapy (LVT), utilizing also the videocapillaroscope coupled with diode laser 532 nm.Results. All types of telangiectases of the face disappeared, and 22 cases only haven't results on the legs. Relapses had be minus than 10% of cases of legs, and minus than 7% on the face. No side effectives appears in any cases.Conclusions. We achieved four on five objectives purposed, using LVT and LSVT in selected cases. Relapses are the greater problem still no-eliminated.

Stroke is still the most common cause of disability in Poland and in western countries. As many as 80% of patients report reduced upper limb function in the acute phase after stroke. It is estimated that only 5% to 20% of patients experience full functional recovery of an upper limb. In clinical practice, paretic upper limb stimulation after stroke is usually treated as of secondary importance. However, it constantly poses a challenge to physical therapists. The existing procedures do not provide detailed guidelines regarding upper limb rehabilitation model particularly in the first four weeks after stroke. It is hard to predict biological limitations and the effectiveness of upper limb rehabilitation. The aim of this work is to make an attempt at reviewing the knowledge of the current state of early upper limb physiotherapy, its intensity and strategy type as well as neurobiological foundations of the improvement process. Ample scientific evidence confirms that early post-stroke rehabilitation is crucial. There are relatively few foreign (and virtually no Polish) reports related to early upper limb rehabilitation that would take into account the type of exercises and their therapeutic dose. There are still no solid foundations for determining optimal intensity and type of upper limb rehabilitation (including physical and occupational therapy). There is a scarcity of extensive and uniform (in terms of research groups and tools) multicentre investigations aimed at defining an optimal model of upper limb rehabilitation at an early stage after stroke. Thus, a number of questions still remain unanswered.

Udar mózgu nadal pozostaje główną przyczyną niepełnosprawności w Polsce i krajach zachodnich. Aż 80% pacjentów ma obniżoną sprawność kończyny górnej w fazie ostrej po udarze mózgu. Szacuje się, że tylko 5% do 20% pacjentów osiąga pełną poprawę funkcjonalną kończyny górnej. Stymulowanie niedowładnej kończyny górnej po udarze mózgu w praktyce klinicznej jest zwykle traktowane jako drugoplanowe. Stanowi to nadal wyzwanie dla współczesnej fizjoterapii. Istniejące standardy postępowania nie opisują szczegółowo modelu usprawniania kończyny górnej, zwłaszcza w okresie pierwszych 4 tygodni po udarze mózgu. Trudno ocenić, jakie są granice możliwości biologicznych i jaka może być efektywność poprawy sprawności kończyny górnej. Celem tej pracy jest próba podsumowania dotychczasowej wiedzy na temat obecnego stanu wczesnej fizjoterapii kończyny górnej, jej intensywności i rodzaju strategii oraz neurobiologicznego podłoża procesu poprawy. Wiele naukowych dowodów potwierdza, że rehabilitacja we wczesnej fazie poudarowej jest istotna. Stosunkowo mało jest światowych wiarygodnych doniesień, a polskich właściwie barak, odnoszących się do wczesnej fizjoterapii kończyny górnej uwzględniających rodzaj zastosowanych ćwiczeń i ich dawkę terapeutyczną. Nadal brakuje wystarczających przesłanek, aby określić optymalną intensywność i rodzaj stosowanej rehabilitacji kończyny górnej w tym fizjoterapii i terapii zajęciowej. Brakuje dużych, ujednoliconych pod względem grup i narzędzi badawczych wieloośrodkowych badań dla określenia optymalnego modelu rehabilitacji kończyny górnej we wczesnej fazie po udarze mózgu. Zatem nadal wiele pytań pozostaje bez odpowiedzi.
