[Pathogenesis and the contemporary picture of polyneuropathy]. / Patogeneza i wspólczesny obraz polineuropatii.

Demyelinating changes in peripheral nerves are responsible for the neurological symptoms found. Diabetes mellitus is one of the most common causes of polyneuropathy and is found in 8-54% of patients with type I diabetes, 13-46% of patients with type II and 22-66% of alcohol abusers. In turn, chemotherapy, depending on the therapeutic regimens used, is responsible for the symptoms of polyneuropathy in 10-90% of patients. Separate disease syndromes create immunologically determined polyneuropathies. Chronic compression or irritation of the spinal nerves or their roots in diseases of the spine leads to ischemia and neuropathy. The spinal nerve is most often pinched and then there are mixed motor-sensory symptoms. In order to prevent the onset of polyneuropathy, it is necessary to release the nerves from pressure and ischemia as quickly as possible.

[Recognizing Alzheimer's disease in daily practice]. / Rozpoznawanie choroby Alzheimera w codziennej praktyce.

Early diagnosis of Alzheimer's disease (AD) is of great practical importance. The process of differentiating a disease with symptoms of dementia caused by another pathology of the nervous system is based on a subjective assessment. The pathogenesis of AD emphasizes the importance of neuropil beta-amyloid deposition in the brain and the tau protein inside neurons, which is found 20 years before the onset of clinical symptoms of the disease. The number of people suffering from AD doubles every 20 years and in 2050 there will be 115.4 million of them worldwide. The level of education and constant intellectual activity may be a factor protecting against the occurrence of AD. The diagnosis of AD takes into account information obtained from interviews as well as from additional imaging and laboratory tests. The available criteria for AD diagnosis are constantly modified and changed, which makes their application in everyday practice difficult.

[Pro-health cycle lane versus environmental pollution and trauma]. / Prozdrowotne sciezki rowerowe a zanieczyszczenie srodowiska naturalnego i urazowosc.

A bicycle as a mean of transport and recreation, but is it a healthy lifestyle? The construction of numerous cycle lanes in cities and promotion of physical activity aims to encourage the public to move around by bicycle. The aim of mass cycling is to reduce car exhaust emissions and, on the other hand, to improve public health. The paper presents the potential benefits of cycling, but also its negative effects on the human body. Minimizing the danger of using a bicycle lies not only with cyclists, but also with people who are planning to build cycle lane.
