ABSTRACT
Background: False-positive (FP) multiparametric magnetic resonance imaging (MPMRI) obscures and swift needless biopsies in men with a high prostate-specific antigen. Materials and Methods: This was a retrospective study, in which all patients who had been exposed to consecutive MP-MRI of the prostate combined with transrectal ultrasound-guided-magnetic resonance imaging fusion-guided prostate biopsy between 2017 and 2020 were involved in the study. The FP was measured as the number of biopsies that did not encompass prostate cancer divided by the whole number of biopsies. Results: The percentage of FP cases was 51.1%, the highest percentage was found in Prostate Imaging-Reporting and Data System (PI-RADs) 3 (37.7%) and the lowest was detected in PI-RAD 5 (14.5%). Those with FP biopsies are younger, and their total prostate antigen (PSA) and PSA density (PSAD) are significantly lesser. The area under the curve PSAD, age, and total PSA are 0.76, 0.74, and 0.69, respectively. An optimum PSAD value of 0.135 was chosen as a cutoff because it showed the highest sum of sensitivity and specificity, 68% and 69%, respectively. Conclusion: FP results of mpMRI were detected in more than half of our sample, more than one-third were presented in Pi-RAD3, improved imaging techniques to decrease FP rates are highly needed.
ABSTRACT
OBJECTIVES: To explore the cancer prevention-related nutrition knowledge of primary health care physicians towards nutrition and its relation to the development of cancer. MATERIALS AND METHODS: a cross-sectional study was conducted among family physicians in Riyadh, between November 2019 and April 2020. The participants in the current study were surveyed using a self-administered questionnaire. The questionnaire included socio-economic data and data related to the association between nutrition and cancer. RESULTS: The mean correct knowledge score for physicians is good but less than expected (26.5+5.8) 73.6%. Multiple regression revealed that age, position, and nationality to be significantly associated with knowledge of cancer prevention (P<0.05) among physicians. CONCLUSIONS: Primary care physicians have good knowledge about the relation between nutrition and cancer but not sufficient, they should have continuous nutrition educational training programs to ensure safe and sound nutritional advice to patients and for the public about the relation of nutrition and cancer.

Introduction For Sprengel deformity, a variety of operations are available, with Woodward's procedure being a favorable option with good outcomes. This study aims to assess the outcomes of Woodward's procedure with brachial plexus monitoring to prevent the possible complications of nerve injury and consequent deficits. Methods In our study, we included 18 patients with Sprengel deformity treated with Woodward's procedure using intraoperative neuromonitoring for the brachial plexus from 2013 to 2019 at our institute. For each patient, we collected information about age, gender, follow-up duration, affected shoulder side, and presence of an omovertebral bar. Also, preoperative and postoperative degrees of shoulder abduction, Cavendish grade of cosmetic appearance, Rigaults grade, and difference in scapular elevation along with postoperative complications were all measured to evaluate the outcomes. Results The mean duration of follow-up was 12 months. The average preoperative Cavendish grade was 3.1, which decreased to 1.3 on the final follow-up. The average preoperative Rigault grade was 2.5, which has decreased to an average of 1.8. The average increase in the degree of shoulder abduction postoperatively was 48.3°. The average preoperative difference in scapular height (mm) was 26.9, which decreased to an average of 12.2. Furthermore, the final outcome was not impacted by the absence or the existence of the omovertebral bar. Conclusion Woodward's procedure using intraoperative neuromonitoring without clavicle osteotomy for Sprengel's deformity successfully corrects the deformity and decreases the risk of iatrogenic brachial plexus injury.
