The aim of the study was to study the characteristics of systemic lupus erythematosus (SLE) in the Egyptian population, comparing it to other populations. We retrospectively studied 207 patients with SLE diagnosed between 1990 and 2005. We obtained clinical features and laboratory data and analyzed them statistically. We studied 151 female and 56 male SLE patients. The female to male ratio was 2.7 to 1 and the mean age at presentation was 10 +/- 2.7 years (range 2-16). The mean disease duration was 6.47 +/- 3.74 years. At diagnosis, musculoskeletal, constitutional and mucocutaneous manifestations were the commonest features. During follow-up, the prevalence of nephritis (67%), hematological manifestations (44.9%), photosensitivity (44%), arthritis (39%), malar rash (38.2%), serositis (32.9%) and neuropsychiatric manifestations (24.25%) increased significantly. Those whose age of onset of the disease was
Aim: Artificial intelligence (AI) is rapidly evolving in healthcare worldwide, especially in surgery. This article reviews important terms used in machine learning and the challenges of deep learning in surgery. Methods: A review of the English literature was carried out focused on the terms “challenges of deep learning” and “surgery” using Medline and PubMed between 2018 and 2022. Results: In total, 54 articles discussed the challenges of deep learning in general. We include 25 articles from various surgical specialties discussing challenges corresponding to their respective specialties. Conclusion: The increased utilization of AI in surgery is faced with a wide variety of technical, ethical, clinical, and business-related challenges. The best way to expedite its expansion in surgery in the safest and most cost-efficient manner is by ensuring that as many surgeons as possible have a clear understanding of basic AI concepts and how they can be applied to the preoperative, intraoperative, postoperative, and long-term follow-up phases of the surgical patient care.
Highlights
Multiple magnet ingestion in children is challenging to diagnose if asymptomatic.
Symptoms include vomiting, abdominal pain, discoloured stools or fever.
Meticulous history, patient examination and investigations are necessary.
Intestinal pressure necrosis and multiple fistulas can occur yet remain asymptomatic.
Resection and anastomosis may be the sole management in such cases.
Cardiovascular morbidity and mortality are highly prevalent among patients with chronic renal failure (CRF). Endothelial dysfunction is regarded as the initial reversible step in the development of atherosclerosis and has been demonstrated in all stages of renal failure. Non-invasive techniques to assess endothelial function have been recently developed and have been proven to predict future mortality in adults. We aimed to assess endothelial function in children with stage 4 chronic kidney disease (CKD 4) on conservative treatment, using a-non invasive, high-resolution, ultrasound Doppler study of the brachial artery flow, correlating it with other clinical and laboratory parameters. This study included 34 children with CKD 4 on conservative treatment who were compared with 30 healthy controls. Flow-mediated dilatation (FMD), nitroglycerin-mediated dilatation (NTG-MD) and FMD/NTG-MD ratio were estimated. FMD was abnormal (< 5%) in 24 patients (71%). FMD and FMD/NTG-MD ratio were significantly lower in patients than in controls (P = 0.001 and P = 0.01, respectively). FMD correlated positively with serum calcium and negatively with alkaline phosphatase. We concluded that endothelial dysfunction is present in children with CKD 4 on conservative treatment and may reflect increased atherogenic and thrombogenic properties of the endothelium, contributing to subsequent adverse cardiovascular outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
