The prevalence of probable overactive bladder and associated risk factors among medical students in Jordan: a cross-sectional study.

BACKGROUND: To discuss the impact of overactive bladder (OAB) on medical students. overactive bladder. is a chronic condition that causes sudden and intense urges to urinate, which can have significant physical and psychological effects on patients' lives. The prevalence of OAB among medical students is relatively high, with some studies reporting rates as high as 35.4%. This research aims to shed light on the prevalence rates and risk factors associated with OAB among medical students in Jordan. METHODS: A cross-sectional study was conducted using an online self-reported questionnaire as the study tool. The questionnaire collected the sociodemographic, health, and academic characteristics of medical students, as well as the new 7-item OABSS score. RESULTS: Out of the total sample of medical students surveyed (n = 525), 44.5% reported experiencing symptoms of OAB. Furthermore, the analysis also revealed that there was a significant difference in the prevalence of OAB between the ages of medical students. In addition, the study also found that there was a significant association between OAB symptoms and basic years, positive history of diagnostic UTI, positive history of recent trauma, high stress, and taking certain medications. CONCLUSIONS: The study highlights the need for further research in this area and emphasizes the possible implications of OAB for medical students, including the need for additional support and resources to manage the condition.

Exploring the Use of YouTube as a Pathology Learning Tool and Its Relationship With Pathology Scores Among Medical Students: Cross-Sectional Study.

BACKGROUND: YouTube is considered one of the most popular sources of information among college students. OBJECTIVE: This study aimed to explore the use of YouTube as a pathology learning tool and its relationship with pathology scores among medical students at Jordanian public universities. METHODS: This cross-sectional, questionnaire-based study included second-year to sixth-year medical students from 6 schools of medicine in Jordan. The questionnaire was distributed among the students using social platforms over a period of 2 months extending from August 2022 to October 2022. The questionnaire included 6 attributes. The first section collected demographic data, and the second section investigated the general use of YouTube and recorded material. The remaining 4 sections targeted the participants who used YouTube to learn pathology including using YouTube for pathology-related content. RESULTS: As of October 2022, 699 students were enrolled in the study. More than 60% (422/699, 60.4%) of the participants were women, and approximately 50% (354/699, 50.6%) were second-year students. The results showed that 96.5% (675/699) of medical students in Jordan were using YouTube in general and 89.1% (623/699) were using it as a source of general information. YouTube use was associated with good and very good scores among the users. In addition, 82.3% (575/699) of medical students in Jordan used YouTube as a learning tool for pathology in particular. These students achieved high scores, with 428 of 699 (61.2%) students scoring above 70%. Most participants (484/699, 69.2%) reported that lectures on YouTube were more interesting than classic teaching and the lectures could enhance the quality of learning (533/699, 76.3%). Studying via YouTube videos was associated with higher odds (odds ratio [OR] 3.86, 95% CI 1.33-11.18) and lower odds (OR 0.27, 95% CI 0.09-0.8) of achieving higher scores in the central nervous system and peripheral nervous system courses, respectively. Watching pathology lectures on YouTube was related to a better chance of attaining higher scores (OR 1.96, 95% CI 1.08-3.57). Surprisingly, spending more time watching pathology videos on YouTube while studying for examinations corresponded with lower performance, with an OR of 0.46 (95% CI 0.26-0.82). CONCLUSIONS: YouTube may play a role in enhancing pathology learning, and aiding in understanding, memorization, recalling information, and obtaining higher scores. Many medical students in Jordan have positive attitudes toward using YouTube as a supplementary pathology learning tool. Based on this, it is recommended that pathology instructors should explore the use of YouTube and other emerging educational tools as potential supplementary learning resources.

Chromophobe renal cell carcinoma with sarcomatoid and heterologous osteosarcoma-like differentiation: a case report and literature review.

Chromophobe renal cell carcinoma (CRCC) is a subtype of renal cell carcinoma (RCC) with a favorable prognosis. Sarcomatoid differentiation in RCC is assumed to be the outcome of the parent tumor's dedifferentiation and associated with poorer prognosis. Sarcomatoid differentiation can be detected in CRCC as well as other subtypes, but the occurrence of divergent osteosarcoma-like components in sarcomatoid CRCC is extremely unusual. Only six cases have been previously reported in the literature, we reviewed them and presented the seventh case in a 71-year-old male who had a left kidney heterogeneous mass. The resected tumor showed a sarcoma-like spindle cell area with an adjacent osteosarcoma area producing lacy bone material and bony trabeculae in a hard area mixed with a typical CRCC. In conclusion, sarcomatoid CRCC with osteosarcomatous differentiation is a very rare tumor and should be kept in mind especially when dealing with small or frozen sections biopsies.

Spontaneous idiopathic intratesticular hemorrhage as a differential diagnosis for acute scrotal pain.

BACKGROUND: Spontaneous idiopathic testicular hemorrhage is an extremely rare entity with few published reports in the literature. CASE PRESENTATION: We report a case of a 15-year-old boy who had been experiencing intense, left scrotal pain for the previous twelve hours. No previous history of trauma or bleeding disorders. The left testis was enlarged and tender. Left orchiectomy was performed. The entire testis was dusty and dark grossly. Microscopic sections show diffuse intratesticular bleeding with intact seminiferous tubules and spermatogenesis. CONCLUSIONS: Spontaneous idiopathic testicular hemorrhage should be considered when evaluating patients with acute scrotal pain. Clinical and ultrasonographic findings and histopathologic evaluation are mandatory to diagnose it.

Bilateral testicular Leydig cell hyperplasia presented incidentally: A case report.

INTRODUCTION: Leydig cell hyperplasia or tumor represents less than 3% of all testicular tumors. It can be defined as an increase in the size and number of Leydig cell within the testicles. These cells are responsible for the production of testosterone in human males. CASE PRESENTATION: Our patient is a forty-eight-year-old male presented with erectile dysfunction and decreased libido for the past six months. Ultrasound of the scrotum show bilateral hypoechoic testicular masses larger on the left size thus left orchidectomy was performed. Histopathology confirmed our diagnosis. DISCUSSION: Leydig cell hyperplasia (LCH) is a rare and mostly benign entity that affects both children and adults. In adults, it might be associated with variety of condition including Klinefelter's syndrome, exogenous human chorionic gonadotropin (hCG) therapy, and many others but it mostly occurs idiopathically. Scrotal ultrasound and tumor markers can be used to diagnose most of the patients with LCH. CONCLUSION: LCH should be differentiated from Leydig cell tumor to avoid unnecessary and sometimes harmful intervention in the future.

Does post-void residual urine volume affect potential recurrence risk for non-muscle invasive bladder cancer?

Aim: Bladder cancer is the second most common urological malignancy after prostate cancer. Increase in the post-void residual (PVR) volume may result in an increase in the risk of cancer recurrence. Methods: Patient demographic data, tumor stage and grade, PVR volume and 2 years follow-up data for recurrence were obtained and evaluated. Results: One-hundred-and-nineteen patients were subdivided into three groups according to PVR urine volume. The increase of PVR volume was related to short recurrence-free survival (RFS) especially for patients with PVR volume of 60 ml or more. Conclusion: Low PVR volume in patients with non-muscle invasive bladder cancer may play a role in reducing cancer recurrence. However further research is needed in this field.

Shear wave elastography in varicocele patients: Prospective study to investigate correlation with semen parameters and histological findings.

AIMS: Shear wave elastosonography (SWE) is a non-invasive ultrasound imaging modality used to assess the mechanical properties of tissues such as rigidity and elasticity. In this prospective study, we investigated the effect of laparoscopic varicocelectomy on the elasticity, degree of fibrosis and function of the testes through SWE and we evaluated the correlation with semen parameters and histology findings. METHODS: Male patients with monolateral left varicocele and progressive alteration of the semen quality were enrolled prospectively. Patients were evaluated before varicocelectomy, 3 and 6 months after surgery with semen analysis, ecocolordoppler US and SWE. In all patients, a left testicular biopsy was performed at the time of varicocelectomy and it was repeated after 6 months in 55% of patients in order to investigate the histological findings and to correlate with SWE results. RESULTS: The study was conducted on 82 patients. SWE showed a statistically significant difference between left and right testicles. Three months after surgery the mean left testicular volume increased, mean left SWE features decreased, and sperm count increased (P values < .0001). The SWE parameters, testicular volume and semen analysis values showed a statistically significant positive correlation between the pre and postoperative results (P value < .0001). The histological alterations were significantly changed 6 months postoperative with a complete morphology recovery in accordance with SWE results. CONCLUSIONS: SWE showed a statistically significant positive correlation with testicular volume, semen analysis and histological findings. This study represents the first investigation that correlates the varicocele, the testis volume, the quality of the seminal fluid ant the histological findings with the ultrasound and SWE values.
