Management of pediatric distal humerus metaphyseal-diaphyseal junction fracture: A systematic review and meta-analysis.

Purpose: Fractures occurring at the metaphyseal-diaphyseal junction of the distal humerus in children are not commonly documented in the literature. Until this moment, there is no gold standard technique regarding its management and most surgeons treat it as a regular supracondylar humerus fracture by conventional pinning. This systematic review explores the relevant literature to assess the efficacy of different techniques. Methods: This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our literature search encompassed several online databases, including PUBMED/MEDLINE, Scopus, Web of Science Core Collection, and Google Scholar. Data from articles that met our general inclusion criteria were extracted and categorized into treatment method groupings. Functional and cosmetic outcomes, demographic characteristics, and complications were the main parameters used to analyze the data. Results: Ten retrospective studies met our inclusion criteria with a total of 178 participants of unilateral pediatric distal humerus metaphyseal-diaphyseal junction fractures. Most literature chose closed reduction and percutaneous pinning in seven articles, followed by elastic stable intramedullary nail technique used in three articles, then conservative treatment was chosen in two articles, while only one article used lateral miniplate and assisted K-wire and another article used combined closed reduction and percutaneous pinning and intramedullary K-wire. As regards the operation time; elastic stable intramedullary nails had the shortest time with a mean of 39.7 min (range: 37.5-41.9 min), while closed reduction and percutaneous pinning had the longest time with a mean of 75.47 min (range: 55.9-92.1 min). The shortest healing time was observed in miniplate with a mean of 7.2 weeks, while the most prolonged was in conservative management with a mean of 12 weeks and closed reduction and percutaneous pinning was a mean of 10 weeks. Regarding Flynn's criteria, all participants received excellent and good except in closed reduction and percutaneous pinning; 13 cases were fair and 2 cases were poor. Regarding complications, the most commonly observed complication after metaphyseal-diaphyseal junction fracture was cubitus varus, the highest incidence was in conservative management (33% of cases), followed by closed reduction and percutaneous pinning (10.9% of cases), the least incidence was observed in elastic stable intramedullary nails (3.77% of cases), and none of the cases treated with mini plate developed this complication. Other complications were observed only with closed reduction and percutaneous pinning; 8.5% of cases developed fixation loss, 6.2% of cases had a significantly reduced range of motion, and one case refractured. Conclusion: Pediatric distal humerus metaphyseal-diaphyseal junction fractures should be distinguished from the more prevalent supracondylar humerus fractures, as conventional pinning techniques are associated with a higher incidence of complications and increased both operative and healing times.Level of evidence: III.

Three-dimensional echocardiographic demonstration of aortic wall erosion after percutaneous atrial septal defect closure.

Although late complications of percutaneous closure of atrial septal defect (ASD), including cardiac erosion and thrombosis, are rare, they are the most lethal. Data are still lacking regarding the usefulness of new imagining modalities, such as three-dimensional echocardiography (3DE), for the detection of these complications. Here, we report the case of a 57-year-old woman in whom cardiac erosion was very well visualized by 3D transesophageal echocardiography (3D TEE) after percutaneous ASD closure.

Effusion and coin shadow: is there a relation? A case report.

BACKGROUND: Malignant pericardial effusion is a common consequence of various types of cancer. The diagnosis of cardiac tamponade in malignant effusion may be challenging, as the typical echocardiographic signs are not met. Patients with cancer can present with cardiac tamponade in form of tachycardia (rather that hypotension) that improves after pericardiocentesis. CASE SUMMARY: A 70-year-old female patient presented to the emergency department with rapid development of shortness of breath over a week. Her past medical history included oesophageal carcinoma 1 year before presentation. This was complicated by dysphagia for which the patient underwent oesophageal stenting 5 months before admission. On admission, the patient was in respiratory distress, tachycardia; however, she was normotensive. Echocardiography revealed massive circumferential pericardial effusion. Apart from significant respiratory variation in mitral and tricuspid inflow, the echocardiographic features of tamponade were absent. We discuss on how we applied European Society of Cardiology guidelines in order to calculate the pericardiocentesis score and make a firm management plan. Despite that the patient was normotensive, the pericardiocentesis score was 13.5, so urgent pericardiocentesis was done followed by immediate improvement. DISCUSSION: This case demonstrates that oncology patients can present with tamponade in the form of tachycardia rather than hypotension as the slow course of effusion formation allows the body to compensate by increasing the heart rate and peripheral vascular resistance, thus maintaining the blood pressure. The application of 'pericardiocentesis score' is very helpful in such patients. Score equal or greater than 6 necessitates urgent pericardiocentesis even if the blood pressure is normal.
