Relative contribution of digital rectal examination and transrectal ultrasonography in interpreting serum prostate-specific antigen values for screening prostate cancer in Arab men

Awareness and Acceptance of Digital Rectal Examination for the Clinical Evaluation of Anorectal Conditions Among the Saudi Population: A Cross-Sectional Study

INTRODUCTION

Digital rectal examination (DRE) is an important diagnostic tool used by physicians to resolve several confusing clinical situations. The history and physical examination cannot be complete without performing a DRE. Any patient that presents with abdominal complaints (e.g., diarrhea, constipation, nausea, vomiting, abdominal or rectal pain, bleeding) needs a DRE which is important for detecting warning signs of serious conditions that require further investigation and evaluation such as malignancies. Therefore, our aim was to assess and measure the awareness of the Saudi population regarding the importance and acceptance to perform DRE.

METHODS

This cross-sectional study was conducted in Riyadh, the capital city of Saudi Arabia, using an online survey between September 2022 and March 2023; the targeted participants were adults between the ages of 18 to 75.

RESULTS

The study indicated that the general community awareness of DRE is low, with only 59.1% of participants having heard of DRE and 14.6% having undergone the procedure previously. The majority of individuals (60.9%) were willing to undergo DRE if a healthcare provider suggested it. Participants' knowledge of DRE's ability to detect various anorectal diseases varied. While the majority of individuals believed DRE could detect hemorrhoids, just 40.4% believed DRE could help detect colorectal cancer. Chronic constipation or diarrhea, feces-induced stretching, and prolonged sitting were the most oft-cited causes of hemorrhoids. Anemia was the most often reported consequence of hemorrhoids, followed by hypertension and diabetes.

CONCLUSION

The significance of DRE as a screening tool for the early detection and prevention of anorectal problems, as well as the need for adequate care and treatment of hemorrhoids to prevent complications, are highlighted by these findings. Healthcare practitioners should actively recommend and provide information about DRE and other screening technologies, as well as address their patients' concerns and misconceptions.

Lectins applied to diagnosis and treatment of prostate cancer and benign hyperplasia: A review

Environmental factors, as well as genetic factors, contribute to the increase in prostate cancer cases (PCa), the second leading cause of cancer death in men. This fact calls for the development of more reliable, quick and low-cost early detection tests to distinguish between malignant and benign cases. Abnormal cell glycosylation pattern is a promising PCa marker for this purpose. Proteins, such as lectins can decode the information contained in the glycosylation patterns. Several studies have reported on applications of plant lectins as diagnostic tools for PCa considering the ability to differentiate it from benign cases. In addition, they can be used to detect, separate and differentiate the glycosylation patterns of cells or proteins present in serum, urine and semen. Herein, we present an overview of these studies, showing the lectins that map glycans differentially expressed in PCa, as well as benign hyperplasia (BPH). We further review their applications in biosensors, histochemical tests, immunoassays, chromatography, arrays and, finally, their therapeutic potential. This is the first study to review vegetable lectins applied specifically to PCa.
