Fever is a common symptom in children, however knowledge about management in the course of it is insufficient. Errors committed in this respect, not only parents, but also doctors. Concerns relate to methods for marking and interpreting the results of temperature measurement, the dosage of drugs, the use of physical methods of cooling the body, as well as reaching for antibiotics. Therefore, to popularize the latest knowledge about fever constantly has its justification. The paper is a sectional information concerning fever in children, from the recognition by the treatment, and education ending.

The study presents comparatively normal and compensatory features of stabilization in two boys, one of whom with normal posture and the other onewith faulty posture. According to the neurodevelopmental concept, body stabilization is conditioned by postural tone that is generated by CNS. In case of even mild dysfunctions of CNS the postural tone is decreased, which causes involvement of different types of compensation mechanisms in order to obtain body stabilization. Features of compensation are visible in:
- static conditions, as postural faults
- improper arrangement of body segments,
- dynamic conditions, in the form of difficulties in accomplishment of many motor acts.
The boy with faulty posture has difficulties in performing the motor tasks. This means that proper performance of movement is conditioned by the abilityto assume correct initial position. Taking the above into consideration, different motor tasks carried out by the two boys were presented on the photographs. The boy with faulty posturehas problems with central stabilization and either uses distal stabilization in order to obtain a given position or he simply cannot accomplish a task.

Hepatitis A is a self-limited, acute infectious disease caused by the hepatitis A virus (HAV). Most commonly HAV is transmitted by the fecal-oral route,rarely by blood or sexually. Currently, the epidemiological situation in the world varies among regions, each year there are approximately 1.4 million of new cases. Poland is among the countries with a low incidence rate. In the recent years, typically there were under 100 new cases of hepatitis Aannually, however, every few years a singular increase in the number of cases occurred and an amount of new cases surmounted to a few hundred. Good epidemiological situation leads to a lack of natural immunity among children and adults in Poland. This in turn increases the risk of acquiring a HAV infection in countries with higher endemicity, that are frequent holiday destinations. In the absence of natural immunity only vaccinations are an effective way of protection against the infection

Newborn infants, particularly preterm more often require transfusions of blood components compared to other patients. Preparation and implementation of procedures and recommendations regarding the indications for their use and the widespread prevention of anemia contributes to a significant reduction in the amount of transfusions performed. Currently, there is no clearly defined indications for supply of red blood cells, various data – both morphological and clinical apply in different parts of the world and of Europe. On the basis of the current recommendations of scientific societies have developed new recommendations for infants with low and very low birth weight, which has been implemented from 2013 in the Department of Neonatology, Medical University in Wrocław. Revised procedure allowed limit the supply of blood components, without adversely affecting the clinical condition of patients. The paper presents not only the recommendations regarding the supply of blood and blood components in neonatology, but also the applicable legal regulations in Poland.
