Introduction: Doxorubicin is one of the most reliable anthracycline chemotherapeutics. Its high efficacy in treating a large range of cancers, however, comes hand in hand with complications. A hallmark of anthracycline drugs, and also their most common side effect, is heart failure caused by the development of dilated cardiomyopathy. Purpose of the study: The purpose of our work is to present the current state of knowledge about the causes of doxorubicin cardiotoxicity and to present known ways to minimize the negative impact on the patient's health. Materials and Methods: We performed a non-systematic review of the Polish and English-language literature available in the database, using the keywords: ,,doxorubicin"; ,,anthracyclines"; ,,cardiotoxicity"; ,,cardiomyopathy"; ,,chemotherapy". Results: Doxorubicin is counted among the first-generation anthracycline cytostatics widely used in cancer chemotherapy. The enormous potential of anthracyclines is a motivator for further attempts to improve these molecules and eliminate side effects. The methods developed so far have led to a reduction in the frequency of cardiovascular incidents, but the risks associated with the use of these drugs are still relatively high and the cost of liposomal forms is high. Summary: The current state of knowledge identifies promising options for improving the well-being of patients undergoing treatment with chemotherapeutic agents. Hopes for effective analogs free of cardiotoxic effects are reasonable, and the use of companion substances is an additional possibility.

Introduction and purpose of the study: Prostate cancer is one of the most common malignancies in the human population worldwide. The continuous development of imaging methods allows for its increased recognition. Conclusions have been drawn that MRI-TRUS (magnetic resonance imaging - transrectal ultrasonography) fusion biopsy is superior to other diagnostic methods. The aim of this study is to review the available studies and publications and determine which method of diagnosing prostate cancer is most effective. Materials and Evidence: We reviewed the literature available on PubMed and Google Scholar using the words "fusion biopsy"; "prostate diagnosis"; "prostate cancer"; "transrectal ultrasonography". Results: The diagnosis of prostate cancer is made possible by a range of tests such as transrectal palpation, measurement of prostate specific antigen, transrectal ultrasonography, needle biopsy and MRI. The combination of biopsy, MRI and transrectal ultrasonography has led to the development of fusion biopsy. It combines the high-resolution features of MRI and the real-time images provided by ultrasound. Conclusions: The higher cost of the test and the need for specialised equipment together with the advanced software required for fusion biopsy ultimately provides a statistically significant higher success rate for the diagnosis of prostate cancer. Mentioned the effects of this method, further development and dissemination is expected.

Introduction: The number of surgeries requiring sedation continues to increase worldwide. Analgesia is one of the main components of anesthesia used during surgical procedures. Despite improvements in surgical techniques, the invention of new analgesics and a significant expansion of knowledge about the pathophysiology of pain, more than 75% of patients experience postoperative pain. Adequate analgesia reduces postoperative complications and shortens the length of hospitalization. Lidocaine is a local anesthetic also used as an antiarrhythmic drug. Studies report that intravenous administration may find application in perioperative analgesia. Aim of the study: The purpose of our study was to determine in which types of surgery the benefits of IVL (Intravenous lidocaine) are greatest.Methods and Evidence: We reviewed the literature available on PubMed using the words "Intravenous lidocaine"; "Perioperative Lidocaine "; "Postoperative pain".Results: IVL has been shown to have a positive effect on reducing opioid doses, postoperative pain intensity, shortening the duration of postoperative bowel obstruction, faster patient rehabilitation and shortening hospitalization. In non-abdominal surgeries, the greatest benefits have been seen in breast surgery, urology and spinal surgery. Lidocaine has low toxicity; only doses several times higher cause adverse effects.Conclusions: IVL should be used during intraabdominal surgery due to its high efficacy. Further studies on a larger group of patients are needed to better determine the effects of IVL in other surgeries. Keywords: "Intravenous lidocaine"; "Perioperative Lidocaine "; "Postoperative pain".

Abstract Introduction and aim of the study: Urolithiasis is a disease involving the formation of deposits in the lumen of the urinary tract. The continued development of minimally invasive treatment methods allows for more effective treatment with greater operator comfort and less risk to the patient. It has been concluded that retrograde intrarenal surgery (RIRS) is superior to other therapeutic methods in many respects. The aim of this study is to review the available studies and publications and to identify potential complications following treatment of kidney and ureteral stones by RIRS, with a particular focus on infectious complications and their risk factors.   Method and materials: We reviewed the literature available on PubMed and Google Scholar, using the words 'urolithiasis'; 'urolithiasis treatment'; 'retrograde intrarenal surgery'; 'infectious complications of retrograde intrarenal surgery'.   Results: Among the risk factors associated with infectious complications after RIRS, long duration of surgery, recent positive urine culture, urinary tract infections or antibiotic use, purulent urine, urinary nitrites, obstructed access through the ureter, struvite stones, co-morbidities play a special role.   Conclusions: Among the complications of surgical treatment of nephrolithiasis and ureteral stones by RIRS, infectious complications are of particular concern. In view of the knowledge of their risk factors, preventive measures should include limiting the duration of surgery, possible antibiotic therapy and considering the use of a larger diameter UAS. This is especially true for patients with abnormal urine results, struvite stones, a history of urinary tract infection or predisposing comorbidities.   Key words: Urolithiasis; Kidney Calculi; Retrograde Intrarenal Surgery; Urolithiasis infection;
