Maintaining a low blood pressure (BP) in children should be an important point of pediatric preventive healthcare. Objectives. In our study, we considered the influence of physiotherapy on the blood pressure level in a group of 233 children aged from 8 to 15 years taking part in a rehabilitation camp for children in the szklarska Poreba mountain resort (95 children in 2014 and 138 children in 2015). Material and methods. the children selected for the study suffered from asthma or recurrent respiratory infections. Measurements were made before and after physiotherapy. During the camp, the children were examined two times in 2014 and three times in 2015. the database created contained 1,208 scores of systolic and diastolic BP. the control group consisted of 50 children whose BP was measured in the same hours, but during the weekend, which was free of physiotherapy. Moreover, the values of heart rate (hr) during the first measurement were recorded, both in 2014 and 2015. Results. systolic BP after physiotherapy was significantly lower than before. this result was achieved in every five measuring sessions. In the control group, BP measured in the afternoon was higher than in the morning. the values of hr were not significantly different. the values of BP before and after physiotherapy between children treated with inhaled glucocorticoids and treated without glucocorticoid were not statistically significant. Conclusions. our studies showed that morning exercise can significantly reduce blood pressure in children throughout the day, even in those who were treated with inhaled glucocorticoids.

Background. the problem of developmental obesity is growing in most countries of the world, reaching an epidemic. excessive body weight in childhood results in a greater likelihood of obesity in adulthood, as well as causing endocrine, orthopedic, cardiological and psychogenic disorders. overweight and obesity appear to be the most important causative factor. Objectives. the aim of the study was to estimate the usefulness of body composition analysis in predicting high blood pressure among children and adolescents and the correlation between the parameters of body mass and blood pressure (BP). Material and methods. children from the age of 8 to 15 with recurrent respiratory tract diseases were selected during a rehabilitation and wellness stay in crr Krus in szklarska Poreba. Body composition analysis was performed using the tanita Mc-780Ma analyzer, and blood pressure was measured with a dial gauge. the study was conducted between 2015 and 2016, creating a database of 325 results sets. Results. statistically significant correlations between systolic blood pressure, diastolic blood pressure, body weight and fat mass content were shown (p < 0.001). BMI and body fat content correlations were also statistically significant (p < 0.001). Conclusions. there is a problem of under-diagnosis of hypertension in the pediatric population. obesity and overweight are connected with abnormal BP and hypertension. the total content of fat mass correlates with abnormal BP and hypertension.

Background. obesity developing in the early years is one of the most important risk factors for cardiovascular diseases. this contributes to the need for the earliest possible diagnosis of overweight in children. there is a noticeable underdiagnosis of obesity, most often in children between 5 and 12 years of age, as well as in adolescents. Objectives. the aim of the study was to estimate the correlation between anthropometric measurements that are most commonly used in the diagnosis of obesity. Material and methods. the study involved 150 children, during their rehabilitation and wellness stay at crr KrUs in szklarska Poreba in 2017. the entire group performed basic anthropometric measurements -height, body weight, waist circumference and thickness of the deltoid skin fold. Body composition analysis was performed using the tanita analyzer. Results. a statistically significant correlation between the studied parameters was assumed (p < 0.001). the parameter showing the highest level of correlation with other measured parameters was the BMi percentile, BMi value and cole index. among the parameters not based on growth and weight in the boys' group, the most important was the percentile of the waist circumference (r = 0.76), while in the girls' group, the content of adipose tissue (r = 0,74). Conclusions. the BMi and centile BMi results were the parameters of the highest value in the diagnosis and monitoring of excessive body weight in children. in addition, neither weight nor growth measurements should be used to determine the amount and location of adipose tissue.

The family Flaviviridae includes arthropod-borne viruses that are transmitted to vertebrates by infected mosquitoes and ticks. There are over a 100 species in this family, most of which are animal pathogens, although it cannot be excluded that some animal flaviviruses will also cause human disease. The family name is due to the discovery of the yellow fever virus and is derived from the Latin word flavus, meaning yellow. Several human-pathogenic flaviviruses have a significant public health impact in different parts of the world and the potential of emerging in previously non-endemic regions. The medically important flaviviruses include among others: dengue, Zika, yellow fever, tick‐borne encephalitis (TBE) and West Nile viruses. Diseases that are caused by these viruses include a spectrum of illnesses ranging from asymptomatic infections to severe and fatal disease. Although the characteristics of these viruses are well defined, they are still unpredictable with increases in disease severity, unusual clinical manifestations, unexpected methods of transmission, long-term persistence, and the discovery of new species. This review compares the epidemiological and clinical features of the medically important flaviviruses and considers the effect of human activity on their evolution and dispersal. Climate change, urbanization and increasing ease of travel have created opportunities for the vector to spread and expand into new human populations. The combination of these factors makes it possible for the family Flaviviridae to change and emerge quickly as a new, potential human pathogen.
