Background/aim: Diabetic foot ulcers and related complications are a major cause of morbidity and hospital admissions. Our aim was to evaluate the risk factors associated with poor outcome in diabetic foot ulcers.
Materials and methods:A prospective study was conducted on patients with diabetic foot ulceration attending the Madinah Teaching Hospital from June 2014 to December 2015. Potential risk factors and laboratory test results at presentation were recorded and their association with outcome (healing vs. amputation) was analyzed using IBM SPSS Statistics for Windows, Version 22.0.Results: In total, 112 patients were studied during our study period. The majority of the patients were male (60.7%) and aged 50 years and older (62.5%). Regarding the outcome, 68% healed completely, 27.7% underwent amputation, and 4.5% died during this period. Patient age of 50 and older, long duration of diabetes (>10 years), rural origin, and heel ulcers were significantly associated with poor outcome (P < 0.05).
Conclusion:Patients with diabetes should have a detailed annual foot examination; those having risk factors for poor outcome require more frequent foot care, patient education, and early referral to tertiary care centers.
Inguinal (inguinoscrotal) hernia and colon cancer are common conditions. However, it is rare for primary colon cancer to exist in an inguinal hernia sac and even rarer for it to perforate. We report such an event in our patient, who had an irreducible left inguinoscrotal hernia containing a sigmoid colon carcinoma that had perforated. This clinical picture can be easily confused with hernia strangulation unless the clinician is alert to the presence of certain sinister symptoms and signs.

To prevent the coronavirus disease 2019 (COVID-19) pandemic and aid restoration to prepandemic normality, global mass vaccination is urgently needed. Inducing herd immunity through mass vaccination has proven to be a highly effective strategy for preventing the spread of many infectious diseases, which protects the most vulnerable population groups that are unable to develop immunity, such as people with immunodeficiencies or weakened immune systems due to underlying medical or debilitating conditions. In achieving global outreach, the maintenance of the vaccine potency, transportation, and needle waste generation become major issues. Moreover, needle phobia and vaccine hesitancy act as hurdles to successful mass vaccination. The use of dissolvable microneedles for COVID-19 vaccination could act as a major paradigm shift in attaining the desired goal to vaccinate billions in the shortest time possible. In addressing these points, we discuss the potential of the use of dissolvable microneedles for COVID-19 vaccination based on the current literature.
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.
