Drugs as important factors causing allergies.

Medications can cause many adverse reactions, both non-immunologic and immunologic ones. Allergies can take many forms, allergic reactions include all types of reactions according to Gell and Coombs. Typically, allergic reactions to drugs are manifested by skin lesions such as maculopapular rash or urticaria and life-threatening systemic reactions such as anaphylaxis. Allergy to drugs is diagnosed based on medical history and a number of specific tests: skin tests, blood tests. In diagnosing the causes of anaphylaxis, the basophil activation test is used to exclude false negative and false positive results of skin tests and specific IgE levels. Allergic reactions to medications usually resolve themselves after discontinuation of the drug. Sometimes in the treatment anti-allergic drugs are used to inhibit the development of skin lesions. After observing any signs of drug allergy it is important to accurately diagnose the cause, since the subsequent exposure to the drug may lead to a strong anaphylactic reaction and consequently death.

Huntington Disease - principles and practice of nutritional management.

Huntington disease (HD) is a degenerative brain disease clinically manifested by the characteristic triad: physical symptoms including involuntary movements and poor coordination, cognitive changes with less ability to organize routine tasks, and some emotional and behavioral disturbances. For patients with HD, feeding is one of the problems they have to face. People with HD often have lower than average body weight and struggle with malnutrition. As a part of therapy, good nutrition is an intervention maintaining health and functional ability for maximally prolonged time. In the early stages of HD, small amounts of blenderized foods given orally are recommended. In more advanced stages, enteral nutrition is essential using gastric, or jejunal tubes for short term. Most severe cases require gastrostomy or gastrojejunostomy. Although enteral feeding is well tolerated by most of the patients, a number of complications may occur, including damage to the nose, pharynx, or esophagus, aspiration pneumonia, sinusitis, metabolic imbalances due to improper nutrient and fluid supply, adverse effects affecting gastrointestinal system, and refeeding syndrome.

Obesity and poverty paradox in developed countries.

Obesity is a civilization disease and the proportion of people suffering from it continues to grow, especially in the developed countries. Number of obese people in Europe has increased threefold over the last 20 years. The paradox of obesity and poverty relationship is observed especially in the developed and developing countries. In developing countries, along with economic development and income growth, the number of people with overweight and obesity is increasing. This paradox has a relationship with both the easy availability and low cost of highly processed foods containing 'empty calories' and no nutritional value. To date, this paradox has been described in the United States and the United Kingdom, although many European countries are also experiencing high percentages of obese people. Among the reasons for the growing obesity in the population of poor people are: higher unemployment, lower education level, and irregular meals. Another cause of obesity is low physical activity, which among the poor is associated with a lack of money for sports equipment. Due to the large rate of deaths caused by diseases directly linked to obesity, the governments of many countries implement prevention programmes of overweight and obesity. These programmes are based primarily on educating the public about a healthy lifestyle based on healthy eating, daily physical activity and avoiding alcohol and cigarettes.

Probiotic lactic acid bacteria and their potential in the prevention and treatment of allergic diseases.

Allergy is one of the most important and very common health problems worldwide. To reduce the proportion of people suffering from allergy, alternative methods of prevention and treatment are sought. The aim of this paper is to present the possibilities of probiotics in the prevention and treatment of allergic diseases. Probiotics are live microorganisms belonging mainly to the lactic acid bacteria. They modify the microflora of the human digestive system, especially the intestinal microflora. Prophylactic administration of probiotics in the early stages of life (naturally in breast milk or milk substitute synthetic compounds) is very important because intestinal microflora plays a huge role in the development of the immune system. Prevention of allergies as early as in the prenatal and postnatal periods provides huge opportunities for inhibiting the growing problem of allergy in emerging and highly developed societies. Effects of probiotic therapy depend on many factors such as the species of the microorganism used, the dose size and characteristics of the bacteria such as viability and capacity of adhesion to the intestinal walls. Authors of several studies showed beneficial effects of probiotics in the perinatal period, infancy, and also in adults in the prevention of atopic dermatitis or allergic rhinitis. Probiotics, due to their immunomodulatory properties and safety of use are a good, natural alternative for the prevention and treatment of many diseases including allergies. It is therefore important to explore the knowledge about their use and to carry out further clinical trials.

Allergy to selected cosmetic ingredients.

In an era in which cosmetics are commonly used, their often prolonged contact with the human body should determine the safety of their use. Often cosmetics are the cause of many side effects, mainly hypersensitivity reactions. Common groups of cosmetic components responsible for side effects are fragrances, preservatives and dyes. This paper focuses on the most allergenic components.

Farmers' occupational diseases of allergenic and zoonotic origin.

Farmers are exposed to a number of biological, physical and chemical factors harmful to the health, resulting from the specific nature of their work environment. As is clear from epidemiological studies about occupational diseases, pneumoconioses and infectious and parasitic diseases are recorded most commonly. Due to the character of farmer's work, the greatest risk to his health is biological hazards in the form of numerous microorganisms and their metabolites, and particles of plants and animals contained in the organic dust and pathogens transmitted by vectors such as ticks. The health status of farmers is often worse than of other professional groups as a result of limited access to health care and lower health literacy. Therefore, farmers should be subject to a system of diagnosing occupational diseases, and many preventive and educational programs concerning health risks associated with their work. The aim of this paper is to characterize occupational diseases of farmers including allergic diseases, tick-borne diseases and zoonoses.

Assessment of microbiological cleanness of selected medicinal herbs in relations to the level of resource fragmentation.

Herbs are commonly used in the food and pharmaceutical industries. Their vast use is connected with their antibacterial or antioxidising properties, as well as numerous pro-health properties. The aim of the presented research was assessment of the quantitative and qualitative composition of moulds which contaminate samples of dried herbs: Sage (Salvia officinalis L.), Camomile (Matricaria chamomilla L.) and Melissa (Mellisa officinalis L.) with different degrees of resource fragmentation. The dried herbs investigated had a characteristic mould content below 1•10(6) CFU/g according to the recommendations of the European Herbal Infusions Association (EHIA). The most contaminated resource turned out to be Camomile, the least--Melissa. The most often isolated moulds were: Aspergillus, Penicillium, Ulocladium, Alternaria. Moreover, it was observed that more fragmented dried herbs were characteristic of lower--by approx. 40-55% microbiological contamination--depending on the type of tested herb, which might be connected with the time of dried herbs' processing, higher aeration, moisture changes or mechanical damaging of fungi's fragments in the case of a resource with higher fragmentation. High contamination of a herbal resource might be harmful for a consumer, and moulds and their metabolites in the form of mitotoxins might constitute a threat for human health. To keep all the sensory features and activity of herbs' active substances, it is extremely important to secure their high microbiological quality.

Causes, symptoms and prevention of food allergy.

Currently, food allergy is considered to be one of the diseases of civilization, which occurs as a result of the changing conditions of life and environmental changes (e.g. increased popularity of cesarean delivery, excessive hygienic regime during the neonatal-infantile period). Based on medical statistics, it can be concluded that this problem will be intensified. Consumption of food is one of the main activities in human life. What and how one eats affects our health. Meals eaten regularly provide the components necessary for the energy metabolism. Multicultural society, travel, and new trends affect the diversity of food consumed. The mechanism of food allergy reaction covers all 4 types of the immune response of the classical division of Gell and Coombs. The percentage of the immune response was assessed by Chandra as follows: type I - 48%, type II - 6%, type III - 10%, and type IV - 18%. The article presents the risk factors for food allergy, most common symptoms, preventive measures and characteristics of food products that are potential allergens.
