RESUMEN
INTRODUCTION: The diagnosis of Kawasaki disease (KD) is based mainly on clinical findings and supported by laboratory tests. Complete KD fulfills the main clinical criteria, while incomplete KD includes patients with fewer main criteria and compatible laboratory or echocardiographic findings. The study compares the demographic, clinical, laboratory, and echocardiographic parameters between the complete and incomplete KD and early and late presenters. Moreover, it describes the coronary manifestations of the study population. METHODOLOGY: A retrospective review of all patients admitted with a diagnosis of KD during the period from January 2010 to September 2020 was conducted. Clinical presentation, laboratory features, echocardiographic observations, and follow-up data were examined. Moreover, the patients were further classified as early presenters (presented within 10 days of fever onset) and late presenters (presented after 10 days of disease onset). A comparison between complete and incomplete KD and early and late presenters was performed for demographic, clinical, and echocardiographic features. RESULTS: A total of 76 patients were admitted with a diagnosis of KD. The median age of presentation was 28 months, with a range of five to 144 months, and the median timing was seven days, with a range of one to 30 days. The median follow-up period was six weeks, with a range of one to 192 weeks. Complete KD was present in 38 patients (50%), and 38 (50%) had incomplete KD. Skin manifestations, oral mucosal changes, skin desquamation, conjunctivitis, and lymphadenopathy were present more in patients with complete KD than incomplete ones. Complete and incomplete diseases did not differ regarding coronary artery lesions. Of the patients, 53 (70%) presented 10 days or less after the onset of fever, and 23 (30%) presented after the 10th day of disease onset. Comparison between early and late presenters revealed significantly greater mucus membrane changes and lymphadenopathy manifestations among the early presenters and coronary artery lesions among the late presenters. CONCLUSION: The clinical features of KD should prompt early referral for evaluation, echocardiography, and early administration of intravenous immunoglobulin to prevent coronary artery complications. The complete form of Kawasaki does not have more frequent coronary artery lesions than the incomplete form. Additionally, late presenters may be at increased risk for coronary artery abnormalities than early presenters.
RESUMEN
Cancer is a major health concern and accounts for one of the main causes of death worldwide. Innovative strategies are needed to aid in the diagnosis and treatment of different types of cancers. Recently, there has been an evolving interest in utilizing nanobodies of camel origin as therapeutic tools against cancer. Nanotechnology uses nanobodies an emerging attractive field that provides promises to researchers in advancing different scientific sectors including medicine and oncology. Nanobodies are characteristically small-sized biologics featured with the ability for deep tissue penetration and dissemination and harbour high stability at high pH and temperatures. The current review highlights the potential use of nanobodies that are naturally secreted in camels' biological fluids, both milk and urine, in the development of nanotechnology-based therapy for treating different typesQuery of cancers and other diseases. Moreover, the role of nano proteomics in the invention of novel therapeutic agents specifically used for cancer intervention is also illustrated.
RESUMEN
King Faisal Specialist Hospital & Research Centre (KFSHRC) is the largest specialized medical center in Saudi Arabia. It performs highly specialized diagnostic imaging procedures with the use of various radionuclides required by sophisticated dual imaging systems. As a leading institution in cancer research, KFSHRC uses both long-lived and short-lived radionuclides. KFSHRC established the first cyclotron facility in the Middle East, which solved the in-house high demand for radionuclides and the difficulty in importing them. As both user and producer of high standard radiopharmaceuticals, KFSHRC generates large volumes of low and high level radioactive wastes. An old and small radioactive facility that was used for storage of radioactive waste was replaced with a bigger warehouse provided with facilities that will reduce radiation exposure of the staff, members of the public, and of the environment in the framework of "as low as reasonably achievable." The experiences and the effectiveness of the radiation protection program on handling and storage of radioactive wastes are presented.
