The use of bevacizumab is increasingly reported in neuro-oncology. The most common schedule is 10 mg/kg every 2 weeks. We retrospectively investigated the efficacy of a 3-week schedule of 5 mg/kg bevacizumab in patients with recurrent glioblastomas. Fourteen patients (median age, 46 years) were included in the study. The median number of bevacizumab cycles was 4 (range, 2-8). Five patients (36%) had a partial response, 7 (50%) had stable disease, and 2 (14%) had progressive disease. No grade III-IV toxicities were observed. The median progression-free and overall survival were 3.6 months and 6.4 months, respectively. Every-3-week low-dose single-agent bevacizumab showed substantial activity and a safe profile in patients with recurrent glioblastoma.

Infective endocarditis carries a high risk of morbidity and mortality with recurrent infections and non-compliance. In the case of right-sided endocarditis, the indications for intervention are less clear. The Angiovac procedure provides a treatment for right-sided endocarditis that is a less-invasive and ideal for a complicated patient population.

Introduction: The frequency of scabies and its relationship with the coronavirus disease 2019 (COVID-19) pandemic is a current scientific curiosity in Turkey and worldwide. The data presented in this article will help raise awareness of dermatologists in situations such as pandemic-induced quarantines where scabies can spread rapidly.
Methodology: This was a retrospective study to compare patients who presented with scabies and were evaluated during the COVID-19 pandemic, with those who presented before and after the pandemic, in terms of the diagnosis ratios.

Introduction: To target psychological support to cancer patients most in need of support, screening for psychological distress has been advocated and, in some settings, also implemented. Still, no prior studies have examined the appropriate 'dosage' and whether screening for distress before cancer treatment may be sufficient or if further screenings during treatment are necessary. We examined the development in symptom trajectories for breast cancer patients with low distress before surgery and explored potential risk factors for developing burdensome symptoms at a later point in time.

Objective: The objective of this study is to assess the predictive utility of perioperative P-wave parameters in patients with paroxysmal atrial fibrillation (PAF) undergoing catheter ablation, and to develop a predictive model using these parameters.
Methods: A total of 213 patients with PAF undergoing catheter ablation were retrospectively analyzed. P-wave parameters were measured within 3 days preoperatively and on the day postoperatively to determine their predictive significance for postoperative PAF recurrence.

This study aims to compare the efficacy of laparoscopic cholecystectomy combined with laparoscopic transcystic common bile duct exploration (LTCBDE), laparoscopic common bile duct exploration (LCBDE), and endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of gallbladder stones with common bile duct stones. We conducted a retrospective comparative analysis based on surgical time, intraoperative blood loss, postoperative recovery metrics, total hospitalization costs, gastrointestinal quality of life index (GIQLI) before and after surgery, and the incidence of postoperative complications. No significant differences were found among the three groups in terms of the surgical success rate, first stone clearance rate, intraoperative blood loss, incidence of postoperative complications, and stone recurrence rate (p > 0.
