In order to improve the percutaneous treatment of coronary artery calcifications (CAC) before stent implantation, methods such as rotational atherectomy (RA), orbital atherectomy (OA), and coronary intravascular lithotripsy (IVL) were invented. These techniques use different mechanisms of action and therefore have various short- and long-term outcomes. IVL employs sonic waves to modify CAC, whereas RA and OA use a rapidly rotating burr or crown. These methods have specific advantages and limitations, regarding their cost-efficiency, the movement of the device, their usefulness given the individual anatomy of both the lesion and the vessel, and the risk of specified complications. This study reviews the key findings of peer-reviewed articles available on Google Scholar with the keywords RA, OA, and IVL. Based on the collected data, successful stent delivery was assessed as 97.7% for OA, 92.4% for IVL, and 92.5% for RA, and 30-day prevalence of MACE (Major Adverse Cardiac Events) in OA—10.4%, IVL—7.2%, and RA—5%. There were no significant differences in the 1-year MACE. Compared to RA, OA and IVL are cost-effective approaches, but this is substantially dependent on the reimbursement system of the particular country. There is no standard method of CAC modification; therefore, a tailor-made approach is required.

Background/Objectives: Damage Control Resuscitation (DCR) is a critical strategy in the management of severe trauma, focusing on the optimisation of the patient’s physiological condition. This study reviews current DCR strategies, emphasizing the mitigation of the “diamond of death”—hypothermia, acidosis, coagulopathy, and hypocalcemia—while addressing complex disturbances like respiratory distress syndrome (ARDS) and (acute kidney injury) AKI in high-ISS (Injury Severity Score) patients. Methods: A systematic review of 59 contemporary sources was conducted, encompassing clinical trials (e.g., CRASH-2), military-to-civilian protocol translations, and guidelines from the C and European Resuscitation Council. The analysis focused on pre-hospital interventions, in-hospital transfusion protocols, and the impact of transport logistics on survival. Results: Evidence highlights that aggressive crystalloid resuscitation (over 5 L) significantly increases mortality, favoring balanced blood component therapy (1:1:1 ratio) or Whole Blood guided by viscoelastic testing like rotational thromboelastometry (ROTEM) or thromboelastography (TEG). Pre-hospital success is driven by rapid hemorrhage control via tourniquets, early administration of Tranexamic Acid (TXA), no aggressive crystalloids, permissive hypotension, proactive calcium supplementation is recommended in early care. Furthermore, the integration of Helicopter Emergency Medical Services (HEMS) is independently associated with improved survival in multi-organ trauma by reducing time to definitive care and facilitating “en-route” damage control. Conclusions: The evolution of rescue strategies focused on mitigating the effects of the diamond of death, combined with the implementation of permissive hypotension and optimized HEMS logistics, constitutes the foundation of a modern model aimed at minimizing mortality in multi-organ trauma.

Background/Objectives: Asthma exacerbations are among the most frequent causes of pediatric emergency department (ED) visits, with over 700,000 annual cases in the United States and a significant number in Europe. Children under five years of age are particularly vulnerable to hospitalization. Methods: As timely assessment of exacerbation severity in the ED is critical, this review synthetizes data about tools such as the Pediatric Respiratory Assessment Measure (PRAM) and the Asthma Severity Score (ASS) aid in evaluating clinical status based on respiratory rate, oxygen saturation, accessory muscle use, and response to treatment. We also analyzed the proper management following established guidelines from GINA, NAEPP and other articles. Results: First-line therapy includes oxygen supplementation, short-acting beta-agonists (SABAs) administered frequently during the first hour, and early systemic corticosteroids. In moderate to severe cases, ipratropium bromide is added. For refractory or life-threatening presentations, intravenous magnesium sulfate, epinephrine, or ventilatory support may be required. Discharge is appropriate when symptoms resolve, oxygen saturation remains >94% on room air, and the child demonstrates adequate inhaler use. Hospitalization is indicated in cases of persistent hypoxemia, poor response, feeding difficulties, or social concerns. Post-discharge care includes thorough caregiver education, medication access, and a personalized asthma action plan to reduce recurrence risk. Conclusions: The effective diagnosis, appropriate exacerbation treatment, monitoring of patients in the post-attack period, as well as successful preventive medication play a key role in the management of pediatric patients with asthma.
