Sonographic Assessment of Renal Transplantation in Adult Saudi Patients: A Cross-Sectional Retrospective Study.

Kidney transplantation stands as a practical and cost-effective treatment option for end-stage renal disease patients, offering an improved quality of life with reduced morbidity when compared with hemodialysis. To evaluate the status of transplanted kidneys in Saudi patients, we conducted a retrospective single-center study at Jazan, Saudi Arabia, involving 46 adult renal recipients enrolled randomly from 2015 to December 2022. Using high-frequency ultrasound, we performed Duplex ultrasound examinations to assess renal allografts. The study revealed that the renal grafts exhibited normal length, with preserved cortical medullary differentiation (CMD) in 84.8% of cases and poor CMD in 15.2%. The echogenicity of the grafts remained normal in 69.6% of instances. Interestingly, we observed a significant rise in resistance index values as the graft duration increased (P = .04), whereas patients with abnormal creatinine levels displayed decreased peak systolic velocity and end-diastolic velocity. Notably, sonographic graft assessments unveiled complications, including perinephric fluid accumulation (8.7%), simple renal cysts (10.86%), hydronephrosis (8.7%), and one case of graft rejection. Receiver operating characteristics analysis for serum blood creatinine levels and abnormal parenchymal findings yielded fair to poor predictive accuracy, with varying sensitivity and specificity measures that lacked statistical significance. In conclusion, our study revealed that most Saudi renal transplant recipients exhibited grafts with normal echogenicity, preserved CMD, and limited perinephric fluid. This investigation provides valuable insights into sonographic changes and Doppler parameters of renal grafts, potentially aiding in the early detection of graft rejection and facilitating diagnostic and therapeutic planning.

Exploring the awareness, attitude, and inclination of healthcare students towards interprofessional education: A cross-sectional study in Saudi Arabia.

Background: Interprofessional education (IPE) is acknowledged to enhance understanding between professionals and to facilitate learning. Healthcare professionals may be better equipped to accept and esteem other healthcare professionals, if interprofessional education is incorporated into undergraduate curricula. The management of challenging patient issues may also significantly benefit from this. As a result, the current study examined interprofessional education in their institutions and students' knowledge of and attitudes toward it. Methodology: We conducted a cross-sectional questionnaire-based study among students from a university in the southwest of Saudi Arabia, who were enrolled in courses in medical, pharmacy, nursing, dentistry, allied health, and public health. Following validation, the questionnaire included six questions to probe their knowledge, ten questions to gauge their attitude, and eleven questions to inquire about the growth and use of IPE in their institutions. Multiple regression and the Kruskal-Wallis test were used to examine the data. Results: The survey involved 600 students, and 66.8% of the respondents were male. Less than one-third of students studying medicine replied to the survey, while students in the public health department had the lowest response rate. Compared to students in other programs, pharmacy students achieved a higher mean attitude score toward IPE (P < 0.001). Additionally, nursing and pharmacy students' mean IPE awareness scores were higher than those of medical students (P < 0.001). However, all program participants firmly agreed that integrating IPE into the curriculum was a good idea. Conclusions: The study found that students of a few programs had awareness and a positive attitude toward interprofessional education. Nonetheless, all of them favored its inclusion in their curriculum. They also stressed the need to educate teaching faculty on interprofessional education, to develop skilled facilitators within their institutions.

Basilar Artery Thrombectomy Between Evidence-Based Medicine and the Real-World Practice: A Single-Center Experience.

Background and Aim: Basilar artery occlusion (BAO) is known for its catastrophic outcomes, whether death or disability, in approximately 70% of patients. Mechanical thrombectomy (MT) has been approved as an intervention in large vessel occlusion of anterior circulation, based on multiple randomized controlled trials (RCTs) and meta-analyses. Even though two RCTs appeared recently, there is still uncertainty about the effect of MT in BAO. Our study aims to report the outcome of MT in BAO and the variables affecting good outcomes and mortality rate. Materials and Methods: We retrospectively collected the clinical and radiological data of 30 BAO patients treated in our center by MT between July 2016 and July 2021. A favorable clinical outcome was considered if mRS was ≤2. A favorable radiological result was considered if modified Thrombolysis in Cerebral Infarction (mTICI) was ≥2b at the end of the intervention. Multiple variables were tested for their effects on favorable clinical outcomes and mortality. Results: The mean age of the 30 patients was 61.23 ± 16.81 years; 20/30 (66.7%) were male. A favorable functional outcome was achieved in 40.7%. Successful revascularization was achieved in 26 patients (86.7%). Mortality at 90 days was observed in 11 patients (36.7%). The presenting National Institute of Health and Stroke Scale (NIHSS) was the only predictor of mortality, and the optimal cut-off value for death was 15 with area under the curve (AUC) = 0.758 (sensitivity 91% and specificity 59%) and P value = 0.02. Conclusion: Thrombectomy is an effective procedure in BAO which has naturally a bad outcome. The presenting NIHSS might be the only predictor of mortality in our study.

Admission Grades as Predictors of Medical Students' Academic Performance: A Cross-Sectional Study from Saudi Arabia.

Background: Admission to medical school is competitive, and different countries use various tests in addition to high school grades to minimize selection bias. A few studies have been conducted to evaluate the usefulness of these tests as predictors for students' academic performance. In this article, we aimed to assess factors that influenced students' grades in medical school. Methods: A cross-sectional study included all students who graduated from the Faculty of Medicine at Jazan University between 2018 and 2020. Scores of the included participants were extracted from the registry of Jazan University, and additional questions about study habits were completed by the included students. Descriptive, univariate, and multivariate analyses were performed for the factors that impacted academic performance. Results: There were 331 included candidates, and the majority of them were female (53%). About 60% of the participants were medical residents at the time of the study, and 40% were interns. Univariate and multivariate analyses indicated that grades in high school and the pre-requisite tests were positively associated with students' academic performance. Further, studying more than two hours per day was positively correlated with better grades in medical school. Conclusion: Scores of the admission tests can serve as predictors for student performance in medical school. National studies are deemed essential to evaluate additional admission tests for medical school, an action that would minimize selection bias.

Effectiveness of a Short Course on Undergraduate Medical Students' Acquisition of Basic Ultrasound Skills: Findings from a Saudi University.

Background: Medical schools in Saudi Arabia generally do not integrate ultrasound training in undergraduate medical study despite its widespread use. Objective: To determine the efficiency of a short course in acquiring basic ultrasound skills at the undergraduate medical level. Subjects and Methods: Fourth-year medical students of Jazan University (2016/2017; N = 118) were divided into 13 groups. A radiology expert provided each group with a 50-min lecture on "ultrasound in clinical practice" and a 2-h hands-on ultrasound training session. Then, the students were invited to participate in the study by completing a questionnaire eliciting data regarding their opinion, experiences, and satisfaction level for the session and then undertaking skill assessment using two OSCE stations. Results: Eighty-one students (68.6%) were enrolled in the study (male: 42; female: 39). The mean scores were high for handling the probe (4.33 ± 1.01) and identifying kidney (4.46 ± 1.08) and liver (4.22 ± 0.97), and moderate for identifying spleen (3.89 ± 0.75), aorta (3.35 ± 0.44), and hepatorenal pouch (3.05 ± 0.35). The students were highly satisfied with the course (4.37 ± 1.01). In the first OSCE station that assessed ultrasound techniques, the mean score was 14.96 (of 18 points; 83.11%) for males and 15.40 (85.56%) for females. In the second station that used static ultrasound image with common pathology, the mean score was 2.4 (of 2.5 points) for both males and females. Conclusion: Undergraduate medical students in this study gained adequate skills and satisfaction in terms of using ultrasound and identifying anatomy following the short course. This study highlights the benefits of introducing programs dedicated to ultrasound for undergraduate medical students in Saudi Arabia.

Incidence of Gallbladder Stone Formation After Bariatric Surgery Using Ultrasound Imaging in the Southern Region of Saudi Arabia.

Background Bariatric surgery is performed for accomplishing weight loss, which can save patients from diseases associated with morbid obesity. However, rapid weight loss is one of the most important risk factors contributing to the formation of gallbladder stones. The aim of this study is to investigate the prevalence of gallstone formation among patients in the southern region of Saudi Arabia who underwent bariatric surgery and to evaluate the association between several parameters and gallstone development in these patients. Methods A retrospective study was conducted including 57 patients who did not have gallstones in the preoperative abdominal ultrasound examinations. Demographic data, such as age and gender, were obtained along with other parameters like weight loss after surgery, and time elapsed between the surgery to post-surgery US examination. The findings of the US examinations were collected and analyzed. Data were analyzed to obtain descriptive and inferential statistics. A correlation matrix to investigate the dependence between variables was conducted. Results Patients in this study underwent either sleeve gastrectomy (87.7% [n = 50]) or gastric banding procedures (12.3% [n = 7]). The occurrence of cholecystectomy was 46% after sleeve gastrectomy and 71.1% after gastric band procedures. The majority of the patients (57.9%) lost weight after surgery in the range of 20 to 40 kg. The time elapses between the surgery to post-surgery ultrasonography examination varied among patients, where less than one year, one to three years, and three to six years accounted for 47.4%, 43.9%, and 8.8%, respectively. Gallstone formation after the surgery was found in 35 (61.4%) of the total cases. Among patients who developed gallbladder stones after bariatric surgery, 62.9%, 28.4%, and 8.6% were within less than one year, one to three years, and three to six years, respectively. The results suggest a statistically significant correlation betweengallstone formation and​​​ the time elapsed after the surgery (P = 0.008) and the type of bariatric surgery (P = 0.006). Conclusion The current study found that the overall incidence rate of gallbladder stones after bariatric surgery is 61.4%. The study assumed a possible higher incidence of gallbladder stones following bariatric surgery among the population in the southern region of Saudi Arabia compared to incidence rates reported in the literature. The type of bariatric surgery and the time elapsed after the surgery were found to be of value in predicting the formation of gallstones.

Consistency in Distribution of Facial Skin Cancers Treated With Mohs Micrographic Surgery.

Mohs micrographic surgery (MMS) has become the standard of treatment for skin malignancies of the head and neck. However, there is a paucity of literature describing facial distributions of MMS. Anatomical location of skin cancer is an important feature to study as it can affect prognosis as well as pathogenesis of skin cancers. This study aims to analyze consistency in head and neck MMS anatomical distributions and compare differences between multiple centers. The study retrospectively reviews 5871 MMS cases performed at a single center in Chevy Chase, Maryland from January 2014 through December 2019. Results show distributions of skin cancers on the face treated with MMS consistently occur at the same anatomical sites year after year with minimal variance. This knowledge of consistency provides a foundation for future studies because it allows for comparison. Comparing and contrasting data across multiple centers can elucidate regional characteristics that may impact the pathogenesis and distribution of facial skin tumors. Many regional or demographical factors may be important in the development of cutaneous malignancies. This information should be considered when assessing risk factors for cancerous skin lesions.J Drugs Dermatol. 2022;21(5):506-509. doi:10.36849/JDD.6143.

Ultrasound Imaging versus Radiographs in Differentiating Periapical Lesions: A Systematic Review.

BACKGROUND: Ultrasonography is a non-invasive method of diagnosing periapical lesions while radiologic methods are more common. Periapical lesions due to endodontic infection are one of the most common causes of periapical radiolucency that need to be distinguished to help determine the course of treatment. This review aimed to examine the accuracy of ultrasound and compare it to radiographs in distinguishing these lesions in vivo. METHODS: This review process followed the PRISMA guidelines. A literature search of databases (PubMed, Scopus, Embase, and Web of Science) was conducted without any restrictions on time. Articles available in English were included. The selection was done according to the inclusion and exclusion criteria. The QUADAS-2 tool was used to assess the quality of the studies. RESULTS: The search provided a total of 87 articles, out of which, five were selected for the final review. In all the studies, ultrasound had higher accuracy in distinguishing periapical lesions. All the studies indicated a risk of bias, especially in patient selection. CONCLUSION: Within limitations, the study indicates that ultrasound is a better diagnostic tool to distinguish periapical lesions compared to radiographs but further studies with well-designed, rigorous protocols and low risk of bias are needed to provide stronger evidence.

Comparison of three embolic materials at partial splenic artery embolization for hypersplenism: clinical, laboratory, and radiological outcomes.

PURPOSE: To compare effectiveness of three widely used embolic agents in partial splenic embolization (PSE) by analyzing their clinical, laboratory, and radiological outcomes within one year of follow-up. MATERIALS AND METHODS: This retrospective study examined 179 patients who underwent PSE to manage hypersplenism secondary to cirrhosis. Patients were divided into 3 groups according to embolic agent used. Group 1 (gelatin sponge) included 65 patients, group 2 (embospheres) included 58 patients, and group 3 (PVA) included 56 patients. Clinical, laboratory, and radiological outcomes were compared between groups. RESULTS: The technical success rate was 100% in all groups. Pain as a major complication was lower in the gelatin sponge group (20%) compared to the embosphere group (31%) and PVA group (32.3%). Major complications other than pain were found in 20.1%; 24.6% in gelatin sponge group, 15.5% in embosphere group and 19.6% in PVA group (p = 0.045). WBCs and platelet counts showed a significant increase after PSE in all groups. Entire splenic volume as measured by computed tomography after PSE showed no significant difference among the 3 groups; however, the volume of infarcted spleen was significantly lower in the gelatin sponge group compared to other two groups (p = 0.001). The splenic span was significantly reduced one-year post-procedure in three groups (p = 0.006), and it was significantly less in embosphere and PVA groups compared to gelatin sponge group (p < 0.05). Recurrent bleeding was higher in gelatin sponge group (p < 0.05). CONCLUSIONS: Permanent embolic materials achieved better laboratory and radiological outcomes than gelatin sponge particles in PSE of cirrhotic hypersplenism patients. However, permanent particles were associated with greater abdominal pain.

Comparison of the CO-RADS and the RSNA chest CT classification system concerning sensitivity and reliability for the diagnosis of COVID-19 pneumonia.

BACKGROUND: The Radiological Society of North America (RSNA) recently published a chest CT classification system and Dutch Association for Radiology has announced Coronavirus disease 2019 (COVID-19) reporting and data system (CO-RADS) to provide guidelines to radiologists who interpret chest CT images of patients with suspected COVID-19 pneumonia. This study aimed to compare CO-RADS and RSNA classification with respect to their sensitivity and reliability for diagnosis of COVID-19 pneumonia. RESULTS: A retrospective study assessed consecutive CT chest imaging of 359 COVID-19-positive patients. Three experienced radiologists who were aware of the final diagnosis of all patients, independently categorized each patient according to CO-RADS and RSNA classification. RT-PCR test performed within one week of chest CT scan was used as a reference standard for calculating sensitivity of each system. Kappa statistics and intraclass correlation coefficient were used to assess reliability of each system. The study group included 359 patients (180 men, 179 women; mean age, 45 ± 16.9 years). Considering combination of CO-RADS 3, 4 and 5 and combination of typical and indeterminate RSNA categories as positive predictors for COVID-19 diagnosis, the overall sensitivity was the same for both classification systems (72.7%). Applying both systems in moderate and severe/critically ill patients resulted in a significant increase in sensitivity (94.7% and 97.8%, respectively). The overall inter-reviewer agreement was excellent for CO-RADS (κ = 0.801), and good for RSNA classification (κ = 0.781). CONCLUSION: CO-RADS and RSNA chest CT classification systems are comparable in diagnosis of COVID-19 pneumonia with similar sensitivity and reliability.

Combined therapy with conventional trans-arterial chemoembolization (cTACE) and microwave ablation (MWA) for hepatocellular carcinoma >3-<5 cm.

PURPOSE: To compare safety and efficacy of combined therapy with conventional transarterial chemoembolization (cTACE)+microwave ablation (MWA) versus only TACE or MWA for treatment of hepatocellular carcinoma (HCC) >3-<5 cm. METHODS: This randomized controlled trial (NCT04721470) screened 278 patients with HCC >3-<5 cm. Patients were randomized into three groups: 90 underwent TACE (Group 1); 95 underwent MWA (Group 2); and 93 underwent combined therapy (Group 3). Patients were followed-up with contrast-enhanced CT or MRI. Images were evaluated and compared for treatment response and adverse events based on modified response evaluation criteria in solid tumor. Serum alpha-fetoprotein (AFP) concentration was measured at baseline and during every follow-up visit. RESULTS: Final analysis included 265 patients (154 men, 111 women; mean age = 54.5 ± 11.8 years; range = 38-76 years). Complete response was achieved by 86.5% of patients who received combined therapy compared with 54.8% with only TACE and 56.5% with only MWA (p = 0.0002). The recurrence rate after 12 months was significantly lower in Group 3 (22.47%) than Groups 1 (60.7%) and 2 (51.1%) (p = 0.0001). The overall survival rate (three years after therapy) was significantly higher in Group 3 (69.6%) than Groups 1 (54.7%) and 2 (54.3%) (p = 0.02). The mean progression-free survival was significantly higher in Group 3 than groups 1 and 2 (p < 0.001). A decrease in AFP concentration was seen in 75%, 63%, and 48% patients of Group 3, 2, and 1, respectively. CONCLUSIONS: Combined therapy with cTACE + MWA is safe, well-tolerated, and more effective than TACE or MWA alone for treatment of HCC >3-<5 cm.

Mohs micrographic surgery for digital melanoma and nonmelanoma skin cancers.

Treatment of digital skin cancers is challenging due to various functional and cosmetic implications. Traditionally, routine treatment includes radical amputation, but digital skin cancers are increasingly being treated with more conservative, tissue-sparing methods such as Mohs micrographic surgery (MMS), which provides excellent tissue conservation and margin control when used to treat melanoma and nonmelanoma skin cancers (NMSCs). In this study, we conducted a retrospective chart review to evaluate clinical outcomes following MMS for treatment of digital melanoma and NMSCs.

Penile squamous cell carcinoma with urethral extension treated with Mohs micrographic surgery.

Penile squamous cell carcinoma (SCC) with considerable urethral extension is uncommon and difficult to manage. It often is resistant to less invasive and nonsurgical treatments and frequently results in partial or total penectomy, which can lead to cosmetic disfigurement, functional issues, and psychological distress. We report a case of penile SCC in situ with considerable urethral extension with a focus of cells suspicious for moderately well-differentiated and invasive SCC that was treated with Mohs micrographic surgery (MMS). A review of the literature on penile tumors treated with MMS also is provided.

Facial Basal Cell Carcinoma in Patients Younger Than 40.

INTRODUCTION: The incidence of basal cell carcinoma in the population younger than 40 years is rising, and a majority of basal cell carcinomas occur on the head and neck. Our objective was to determine whether basal cell carcinomas in the population younger than 40 years occur more frequently at the forehead and its subunits (forehead proper, temple, suprabrow, and glabella). METHODS: We performed a retrospective case review of 4,337 basal cell carcinomas in 3,223 patients treated with Mohs micrographic surgery. RESULTS: Patients younger than 40 showed 2.2 fold increased odds of developing BCC at the forehead. Being younger than 40 was associated with more than 2.5 times higher odds of developing BCC at the forehead proper and 2.0 times higher likelihood of developing BCC at the temple. Females were associated with 3.8 fold higher odds of developing BCC at the glabella; however, they were less likely to develop BCC at the temple. DISCUSSION: There may be underlying differences in the pathogenesis and natural history of basal cell carcinoma in the younger population, and between males and females; alternatively, lifestyle factors may also play a role.

Intraoperative Immunostaining for Cytokeratin-7 During Mohs Micrographic Surgery Demonstrates Low Local Recurrence Rates in Extramammary Paget's Disease.

BACKGROUND: Extramammary Paget's disease (EMPD) is a rare intraepithelial malignancy with high recurrence rates following standard surgical treatments, ranging from 22% to 60% in large retrospective reviews. OBJECTIVE: To evaluate the local recurrence rate of Mohs micrographic surgery (MMS) supplemented with intraoperative immunohistochemistry for cytokeratin-7 (MMS + CK-7) for primary and recurrent EMPD. MATERIALS AND METHODS: Retrospective, multi-center, cross-sectional study of patients treated using MMS + CK-7. Demographic, clinicopathologic, treatment, and follow-up data were obtained by chart review. RESULTS: The observed local recurrence rate for MMS + CK-7 is 3.3% (2/61 tumors) with a mean follow-up of 43.5 months (1-120 months). Local recurrence occurred in 2.3% (1/43) of primary tumors and 5.6% (1/18) of recurrent tumors. Kaplan-Meier 5-year tumor-free rates are 94.6% overall, 97.1% for primary tumors, and 80.0% for recurrent tumors. The Kaplan-Meier 5-year tumor-free rates for all EMPD tumors treated with MMS + CK-7 versus a historical cohort of MMS alone are 94.6% versus 72.0% (p = .012). CONCLUSION: MMS + CK-7 is an effective treatment for EMPD, demonstrating improved outcomes compared with historical controls.

Melanocytes in nonlesional sun-exposed skin: a multicenter comparative study.

BACKGROUND: There are limited data regarding melanocyte density and distribution on sun-exposed skin of the head and neck, in particular, comparing morphology (hematoxylin-eosin [H&E] staining) and immunohistochemistry (Melan-A staining) on formalin-fixed tissue. Furthermore, comparisons of melanocyte density between distinct geographic populations have not been made using these methods. This information would be useful for physicians who use histologic criteria to diagnose and treat lentigo maligna. OBJECTIVE: We aimed to characterize the density and distribution of melanocytes using Melan-A and H&E stains on nonlesional sun-exposed skin of the face and neck, and compare the results between patients seen in Florida and Minnesota. We also aimed to quantify the presence and extent of features considered characteristic of melanoma in these noncancerous specimens of sun-damaged skin. The overall goal was to be able to provide this information to physicians who perform histopathologic interpretations of skin biopsy specimens to potentially prevent the overdiagnosis of melanoma. METHODS: In all, 100 patients undergoing Mohs micrographic and reconstructive surgery for basal cell and squamous cell carcinoma were enrolled, 50 each at the two sites. Permanent tissue sections were prepared from sun-exposed skin without clinical lesions. Melanocyte density and distribution were quantified. RESULTS: The overall median and 90th percentile, respectively, of melanocytes per high-power field was 9 and 14 on the H&E-stained sections and 11 and 19 on the Melan-A-stained sections. The means were 9.3 and 12.0, respectively (P < .001). There was evidence that melanocyte densities were higher in patients in Florida than in Minnesota, at least using H&E staining. There was evidence of lower melanocyte densities with increasing age, more so for Melan-A than H&E staining, and higher densities in men using Melan-A. Confluence was noted in 24% of cases using H&E and 45% using Melan-A. More than two thirds of these were classified as having mild confluence, whereas the others demonstrated higher amounts of confluence (3-8 melanocytes). Only 37 patients had a follicle present; of these, 7 patients had follicular extension although this did not extend beyond 1 mm in depth. Cytologic atypia was noted in 19 of the 100 patients; pagetoid spread was found in 3. LIMITATIONS: This was a selected population of patients; results may not be generalizable to the wider population. Variables such as contours of the epidermis (rete density), density of hair follicles, and epidermal thickness may affect the reproducibility of the results. Melanomas were not included for comparison. CONCLUSION: Relatively high melanocyte density, mild to moderate confluence of melanocytes, focal pagetosis, superficial follicular extension (<1.0 mm), and mild or moderate cytologic atypia may be observed in the absence of a melanocytic neoplasm. It is important for physicians to be aware of these findings so that such features are interpreted appropriately when making a histologic assessment that may ultimately influence therapy and outcome.
