Registered incidence of acute upper respiratory tract infections diagnosed by primary care physicians in Poland - 5-year retrospective analysis of the national health insurance database.

Introduction And Objective: Upper respiratory tract infection (URTIs), caused by a variety of viruses and sometimes by bacteria, represents the most common acute illness in primary health care. The aim of the study was to explore the registered incidence of URTIs in Poland in the period between 2015-2019, and its burden on the health care system.

Material And Methods: A retrospective analysis was carried out of all medical encounters in Poland registered within the national billing database of public healthcare services.

[Comparison of Two Minimally Invasive Osteosynthesis Techniques for Radial Head Fractures in Paediatric Patients].

PURPOSE OF THE STUDY Radial head fractures in paediatric patients account for 5-19% of all elbow injuries and approximately 1% of all fractures in children. Non-displaced fractures are treated with plaster cast fixation. If the fracture is displaced, we proceed to closed reduction, or to osteosynthesis in case of unstable fragments.

[Temporary Hemiepiphysiodesis in the Correction of Axial Deformities for Genua Valga: Retrospective Assessment and Comparison of Outcomes Achieved with the Use of Eight-Figure Plates and Blount Staples].

PURPOSE OF THE STUDY Axial deformities of the lower limbs of various aetiologies are relatively common orthopaedic diagnoses in paediatric population. Fixed deformity is an indication for correction in order to reduce the pain and to delay the early osteoarthrosis of adjacent joints and pain. Temporary hemiepiphysiodesis is technically a fairly simple method for modulating growth at the level of the growth plate and thus correcting the skeletal axis.

Retrospective analysis of necrotizing pneumonia in children between 2015-2019.

Introduction: An increased incidence rate of cases of complicated pneumonia, reaching up to the stage of necrotizing pneumonia was observed at University Hospital Brno in the past period. The aim of this study was to perform a single-center retrospective analysis of patients with acquired inflammatory lung disease requiring surgical treatment, comprising a long-term follow-up group.

Methods: Patients hospitalized for community-acquired pneumonia and surgically treated in the years 2015-2019 were analyzed.

[Comparison of Two Methods of Minimally Invasive Osteosynthesis for Proximal Radius Fractures in Paediatric Patients].

PURPOSE OF THE STUDY The presented study was construed as a retrospective multicentric clinical study focused on paediatric skeletal injuries of the proximal radius. As a general rule, the Type I displaced fractures (Judet classification) are treated conservatively, with no reduction. In the case of Type II-IV displacement, the fracture necessitates reduction or is also transfixed by a Kirschner wire (K-wire) or a Prevot nail (P-nail) where subsequent fragment instability occurs.
