Background: Different methods are used for the analysis of marginal and internal fit of partial crowns, but not all of them are applicable for in vivo studies. The aim of this review is to search the available methods, described in the current literature, to assess marginal and internal fit in partial crowns.
Methods: an electronic search was performed on Pubmed and Web of Science databases to find studies published from 1 January 2017 up to 2 March 2023, following PRISMA guidelines and Cochrane handbook for systematic reviews. The search strategy applied was: "(marginal) AND (fit OR gap OR adaptation OR discrepancy) AND (inlay OR onlay OR partial crown)". In vitro studies which evaluated marginal and internal fit on CAD CAM or 3D printed partial crowns were included in this review. Quality of the studies was assessed by using Quality Assessment Tool For In Vitro Studies (QUIN tool).
Results: 22 studies were included. Among conventional methods, direct view with microscope, indirect view on resin replicas, and silicone replica technique (SRT) were used. Considering new digital methods, micro-CT, SRT 3D and triple scan technique (TST) were applied.
Conclusions: Among 2D methods, direct view technique is the most used marginal fit analysis. For a more comprehensive evaluation, a 3D digital analysis is suggested. SRT and indirect view are the only 2D methods available for in vivo analysis. A protocol for the application of TST for assessment in vivo is now available, but no studies are reported in literature yet.

Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.
Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.

Background: Nodular hidradenoma (NH) is a rare benign adnexal tumor originating from sweat glands, often misdiagnosed due to nonspecific clinical manifestations. Ultrasonography (US) plays a critical role in the diagnosis of skin tumors, yet systematic descriptions of its sonographic features remain limited.
Objective: This study aims to investigate the very-high-frequency (VHF) characteristics of eccrine nodular hidradenoma (ENH) and establish key imaging criteria to differentiate it from other cutaneous/subcutaneous lesions.

Introduction: Organizational resilience is of paramount importance for coping with adversity, particularly in the healthcare sector during crises. The objective of the present study was to evaluate the impact of resilience-based interventions on the well-being of healthcare employees during the pandemic. In this study, resilience-based interventions are defined as organizational actions that strengthen a healthcare institution's capacity to cope with crises-such as ensuring adequate personal protective equipment and staff testing, clear risk-communication, alternative care pathways (e.

Introduction: There are no reports of patients undergoing McKeown esophagectomy for esophageal cancer after undergoing pancreaticoduodenectomy for pancreatic cancer. We report the case of a patient who underwent subtotal esophagectomy and colon reconstruction after pancreaticoduodenectomy using the mesenteric approach.
Case Presentation: A 71-year-old male was diagnosed with advanced esophageal cancer.

Background: Understanding respiratory motions of liver and its surrogate organs is crucial for precise dose delivery in liver cancer radiotherapy. Although these motions have been studied for respiratory motion management in the supine posture, few studies have quantified them and evaluated their correlations in the upright posture.
Purpose: This study quantified the respiratory motions of liver and surrogate organs and evaluated the correlations between the liver motions and surrogate signals for respiratory motion monitoring in both the supine and upright postures.
