The aim of this study was to determine the physicochemical and antioxidant properties of four Polish kinds of honey compared to Manuka honey. Moisture content, water activity as well as color features of honey samples were examined. Phenolic content, ferric reducing/antioxidant power assay (FRAP), and ABTS assay were also quantified. Manuka honey had the highest content of polyphenols and the best antioxidant capacity (based on Tukey's test), whereas multiflower honey had the lowest biological potential. The results indicated that buckwheat Polish honey is a good source of antioxidants compared to Manuka honey and should be more widely consumed. The total polyphenolic content was found to be highly correlated with the FRAP and ABTS values. The results of correlation analysis between dielectric honey parameters and phenolic content as well as antioxidant capacity suggest the possibility of using dielectric loss coefficient and relative permittivity as indicators of honey biological potential.

Respiratory diseases are among the most common disorders found in the clinical practice of every pediatrician. It is estimated that a total of 10-15% of children experience recurrent respiratory tract infections (RRTI). Unfortunately, there is no universal consensus on the definition of recurrent respiratory tract infections in children. In addition, the number of episodes taken into account to define the recurrent nature of infections varies depending on the disease (location of the ongoing infection) and its severity. The most commonly accepted definition is the occurrence of eight or more documented respiratory tract infections per year in preschool children (up to three years old) and six or more in children older than three years, in the absence of any pathological condition underlying recurrent infections. It is very important to select in the group of children suffering from RRTI those who may have primary immunodeficiency. The detailed medical history plays an important role. In cases of positive medical history for immunodeficiency, it is mandatory to conduct a detailed examination of the immune system., (© 2020 MEDPRESS.)

Acute gastroenteritis is one of the most common infection among children. An estimated 500 million children suffer from the condition worldwide each year. In developed countries the course of acute infectious diarrhea is relatively mild, symptoms usually resolve spontaneously within few days. Unfortunately high mortality rate is still a heavyweight problem in countries with low economic development. Acute diarrhea is defined as a change of the consistency of stools to loose or liquid and/ or increase of an amount of defecations to more than 3 during a day. Other symptoms of gastroenteritis include fever, nausea and vomiting. The most common cause of AGE are viruses, with rotavirus being the most frequent agent. The diagnose is based on medical interview, that include mainly precise information about duration and characteristic of occurred symptoms and epidemiological data. The most important part of diagnostic and therapeutic management is dehydration's assessment, which determine the severity of AGE and is used as one of the factors that decide about hospital admission. The majority of patients can be treated in an outpatients settings, hospitalization should be reserved for those requiring enteral or parenteral rehydration. Oral rehydration with hypoosmolar fluids is standard first-line treatment. Other effective procedures include administration of probiotics (Lactobacillus GG , Saccharomyces boulardii), racecadotril and diosmectite as antidiarrheals and ondansetron reducing the intensity of nausea and vomiting. Antibiotherapy should be only considered in exceptional situations. Acute diarrhea is commonly known medical problem, which can be easily treated by following simple, well-defined rules., (© 2019 MEDPRESS.)
