Background: Campylobacter jejuni (C. jejuni) is a common cause of mostly self-limiting enterocolitis. Although rare, myocarditis has been increasingly documented as a complication following campylobacteriosis. Such cases have occurred predominantly in younger males and involved a single causative species, namely C. jejuni. Case report: We report herein a case of myocarditis complicating gastroenteritis in a 23-year-old immunocompetent patient, caused by this bacterium with a favorable outcome. Cardiac magnetic resonance imagining was useful in establishing an early diagnosis. Conclusions: Myocarditis should be considered in younger patients presenting with chest pain and plasmatic troponin elevations. The occurrence of myocarditis complicating C. jejuni is reviewed.

Brain tumors are fatal diseases that require proper treatment, making accurate and timely diagnosis critical for successful treatment. Deep learning (DL) has emerged as a powerful tool for improving the accuracy of brain tumor recognition and underscores the importance of optimizing training parameters and dataset size. These findings demonstrate the feasibility of using DL for accurate and efficient brain tumor recognition, which has significant implications for improving patient outcomes. Accurate and timely diagnosis can greatly improve treatment outcomes and potentially save lives. This paper investigated the impact of DL on brain tumor recognition by utilizing a convolution neural network (CNN) algorithm and Magnetic Resonance Imaging (MRI) dataset of 4000 samples, each with a size of (224×224). The results show that increasing the dataset size led to better performance, with increasing accuracy and generalization of the model. Furthermore, increasing the number of epochs during training improves the accuracy; with 60 epochs as our choice for the DL model, we achieved 97.28℅ accuracy.
