Accuracy of Artificial Intelligence Based Chatbots in Analyzing Orthopedic Pathologies: An Experimental Multi-Observer Analysis.

The rapid development of artificial intelligence (AI) is impacting the medical sector by offering new possibilities for faster and more accurate diagnoses. Symptom checker apps show potential for supporting patient decision-making in this regard. Whether the AI-based decision-making of symptom checker apps shows better performance in diagnostic accuracy and urgency assessment compared to physicians remains unclear.

Safety and Efficacy of a Novel Pneumatically Driven Extracorporeal Membrane Oxygenation Device.

Background: Extracorporeal membrane oxygenation (ECMO) is rapidly becoming a mainstream technology for lung or heart/lung support. Current ECMO devices mostly consist of a power-driven centrifugal pump and a dedicated oxygenator. We studied the safety and efficacy of a novel, fully pneumatically driven ECMO device, which could be used in both venovenous or venoarterial mode in an animal model.

Premalignant nature of oral lichen planus.

The issue as to whether oral lichen planus is a premalignant disorder is still controversial. This study aimed to examine oral malignancies associated with oral lichen planus and to investigate whether oral lichen planus has an intrinsic malignant potential or whether there are also contributing external risk factors. A retrospective cohort study in 200 Caucasian patients with oral lichen planus was conducted between 1991 and 2003.

Oral lichen planus in childhood.

Oral lichen planus is rare in childhood, and only a few reports on this subject have appeared in the literature. Our objective was to report individual cases of oral lichen planus in childhood from our practice and to review the literature on this subject. We recruited patients younger than 18 years with oral lichen planus and documented several clinical aspects, the histopathology, patch tests, and blood examination findings.
