Recurrent pericarditis (RP) complicates approximately 30% of acute pericarditis (AP) cases. We sought to compare the prevalence and severity of objective findings seen in patients with RP. A retrospective single-center study during 2010–2019, including 765 patients diagnosed with AP. Clinical, electrocardiographic, echocardiographic, and laboratory findings were extracted from the local electronic health records. Recurrence during follow-up was documented in 134 patients (17.5%), with a median time to recurrence of 101 (± 59–251) days. The median age was 60 years (IQR 45–72), 68% were male. Most patients were defined as having idiopathic\viral pericarditis (64%). The clinical manifestation during the recurrent event of pericarditis was less prominent or attenuated when compared to the initial event—ECG signs (ST elevation 12% vs. 26%; p = 0.006, Knuckle sign 13% vs. 33%; p < 0.001, ST larger in lead L2 than L3 4% vs. 19%; p < 0.001), pericardial effusion moderate and above (11% vs. 30%; p = 0.02), and inflammatory markers (mean peak CRP levels 66 mg/l vs. 97 mg/l; p < 0.001). Similar results were seen in the subgroup of patients defined as having idiopathic\viral pericarditis. Up to 20% of patients who did not have ECG signs or a significant pericardial effusion in their 1st event demonstrated these findings during the recurrence, though still to a lesser extent compared with those who had these signs in their 1st event. The objective findings of AP are less pronounced during recurrent events. Future studies should focus on the role of advanced biomarkers and imaging in defining true RP events.

Introduction: ERCP with temporary biliary stenting followed by elective cholecystectomy and postoperative ERCP is commonly used to treat choledocholithiasis. While early stent removal (within 3–6 months) is generally recommended, some studies suggest that longer dwell time may not increase morbidity. This study aims to evaluate outcomes associated with prolonged stent dwell time of more than six months. Methods: We conducted a retrospective study of all patients who underwent ERCP with plastic biliary stent insertion, followed by elective cholecystectomy and postoperative ERCP at a single tertiary center between 2018–2024. Patients were divided into early-ERCP (≤6 months) and late-ERCP (>6 months) groups. The primary outcome was the rate of recurrent biliary episodes. Secondary outcomes included urgent postoperative ERCP, stent reinsertion, and the need for additional ERCP’s. Results: A total of 203 patients were included (mean age 58.3 ± 19.8 years). Thirty-one patients (15%) had a stent dwell time of more than six months. Demographic and presenting characteristics were comparable between groups, except for acute cholecystitis, which was more frequent in the early-ERCP group (18% vs. 3.2%, p = 0.034). Recurrent biliary episodes were significantly more frequent in the late-ERCP group (19.4% vs. 5.8%, p = 0.021), as were urgent postoperative ERCP (16.1% vs. 5.2%, p = 0.044), stent reinsertion (35.5% vs. 14.5%, p = 0.008), and additional ERCPs (38.7% vs. 15.7%, p = 0.006). Conclusions: Prolonged biliary stent dwell time beyond six months is associated with significantly higher rates of recurrent biliary episodes, urgent postoperative ERCP, postoperative stent reinsertion, and additional ERCP’s.

Introduction Pigtail catheter (PGC) insertion due to spontaneous pneumothorax (SPT) in the pediatric population has increased markedly in the last years. However, only few studies examined its efficacy in terms of length of hospitalization, rate of complications, and especially pain management comparing to large bore catheter (LBC) insertion. We sought to compare analgetic drug consumption, efficacy, and complication rate between PGC and LBC in children with SPT. Materials and Methods This is a single-center retrospective study of pediatric patients that were admitted to the Schneider Children's Medical Center between 2013 and 2021 with a diagnosis of SPT. The following data were collected: type of drainage (PGC or LBC), duration of drainage, length of hospitalization, number of X-rays, complication rate, surgery during hospitalization, readmission due to SPT, and pain management. Results Seventeen PGC and 23 LBC were inserted in our study. No differences were noted in terms of hospitalization length, tube reposition or replacement, and recurrence of SPT between the groups. Patients with PGC underwent less X-rays comparing to the LBC group (3 X-rays vs. 5, median, p < 0.005). Oral analgesic use in terms of length of therapy was significantly lower in the PGC group than in the LBC group (1 vs. 3+ days, median, p < 0.05). There was no major complication in this cohort. Conclusion PGC is an effective, safe, and less painful alternative compared with a LBC for the drainage of SPT in children.

Background: While the severity of acute appendicitis is routinely evaluated, the significance of its morphological characteristics remains underexplored. This study aimed to evaluate the clinical impacts of appendiceal dimensions. Methods: This retrospective study included patients who underwent appendectomy. Data on demographics, appendiceal morphology, time from admission to surgery, postoperative complications, and readmission rates were analyzed. Statistical tests, including correlation analysis and multivariate regression, were used. p-value ≤ 0.05 was considered statistically significant. Results: Appendix diameter demonstrated positive correlations with age, complicated appendicitis, and surgery duration. Multivariate analysis showed that appendix diameter was found to be a significant predictor of readmission rates, regardless of clinical factors, and has a significant positive association with age in both univariate/multivariate analyses. Conclusions: Our findings demonstrate the significance of appendicular morphology in the prediction of readmission rates and the importance of age-specific diagnostic thresholds. The observed age-related changes may warrant re-evaluation of recent diagnostic criteria.
