Dear Editor, Ticks carry many diseases, bacteria, and viruses and represent a very important healthcare issue both in Croatia and globally. Although most ticks are not infected with pathogens dangerous to humans, some ticks can transmit infectious diseases with significant morbidity and mortality. This is caused by the increasing incidence of many tick-borne diseases over a growing geographical area. Many factors influence which species of ticks are present in a given geographical area, as well as the density of their population and the risk of human exposure to infected ticks...

EVIDENCE ACQUISITION: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Society for Maternal-Fetal Medicine, the International Federation of Gynecology and Obstetrics, the International Society of Ultrasound in Obstetrics and Gynecology, the Royal College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada (SOGC), the Perinatal Society of Australia and New Zealand, the Royal College of Physicians of Ireland, the French College of Gynecologists and Obstetricians (FCGO), and the German Society of Gynecology and Obstetrics on FGR was carried out...

Point-of-care ultrasound can provide critical diagnostic information and add to procedural safety. As with any clinical skill, however, it must be applied by an adequately trained provider, with systems to ensure safety. Training can include a mix of hands-on training with traditional didactics, online coursework, and simulation, but each carries its own costs and benefits worth of review. Following training it is essential to think about assessment of competency in point-of-care ultrasound to reflect the combination of cognitive and procedural skills that makes up the practice...
