Knowledge and Attitude of Celiac Disease Among the Population of Riyadh, Saudi Arabia.

Background and aims Celiac disease (CD) is a chronic autoimmune disease that is characterized by inflammation of the intestinal mucosa, primarily triggered by gluten. So far, the effective management of CD only includes a gluten-free diet. For early diagnosis and management, adequate knowledge and a positive attitude towards CD are crucial. This study aims to investigate the CD-related knowledge and attitudes of the public in Riyadh, Saudi Arabia. Methods A cross-sectional online survey was conducted among individuals aged 16 and older. The data regarding demographic factors, knowledge, and attitudes about CD was collected via an online questionnaire. Statistical analysis was conducted using version 26 of SPSS (IBM Corp., Armonk, NY). Results In the current study, 669 individuals responded to the online survey. The majority of participants (82.1%) were familiar with CD. A total of 59.9% of respondents had adequate knowledge, 32.3% had outstanding knowledge, and 7.8% reported no knowledge of CD. The majority (69.5%) of respondents held negative attitudes concerning CD. The correlation between age and CD knowledge (P<0.05) and attitude (P<0.05) was statistically significant. Similarly, the correlation between occupation and CD knowledge (P<0.05) and attitude (P<0.05) was statistically significant. However, no significant association between gender and CD knowledge (p=0.720) or attitude (p=0.244) was found in males and females. Conclusion This study revealed that the majority of the residents of Riyadh, Saudi Arabia, had an adequate or excellent understanding of CD. However, the majority of respondents had a negative attitude towards CD management.

Innovations in Aortic Valve Replacement: A Comprehensive Overview of the Intuity Rapid Deployment Valve.

Rapid deployment/sutureless (RDS) valves have recently emerged as an innovative surgical solution, providing an alternative to traditional methods of surgical aortic valve replacement (SAVR) by eliminating the need for suture placement and tying. This innovation leads to a reduction in aortic crossclamp and cardiopulmonary bypass times, enhancing the efficiency of the procedure. Among the 2 available RDS valves, the Edwards Intuity valve in particular has been demonstrated to be a particularly promising substitute in the field of SAVR. The Intuity valve distinguishes itself from other RDS and conventional valves by yielding superior outcomes, such as a significant reduction in mortality, increase in the longevity of the valve, and a marked decrease in both mean and peak transvalvular pressure gradients. These benefits collectively contribute to its appeal as a favorable new solution. However, further investigation is needed to conclusively determine the long-term outcomes and safety of RDS valves. Nevertheless, the utilization of the Intuity valve presents an exciting solution to the existing limitations of conventional and minimally invasive SAVR, especially for patients afflicted with severe aortic stenosis.

Prostate cancer among Saudis: a registry review.

Background: Policy makers in Saudi Arabia greatly rely on published studies to make major public health decisions. Prostate cancer (PCa) studies in Saudi Arabia are either outdated or limited to local regions. Aim: The authors aim to analyze the Saudi Cancer Registry to determine the incidence of PCa across all regions of the Kingdom and the risk factors of poor prognosis in the population. Methods: Patients diagnosed with primary PCa from 1 January 2008 to 31 December 2017 were included in the study from the Saudi Cancer Registry. Incidence rates and risk factors for poor survival were calculated. Results: A total of 3607 PCa patients were retrieved. PCa incidence rates ranged from 0.2 to 1.4 per 100 000. Most of the patients were aged 60 and older (86.5%; n=3120), married (97%; n=3497) and lived in the central region (38.1%; n=1375). The mean age at diagnosis was 71.1 (10.8) years. Over half of all tumors were poorly differentiated (64.2%; n=2317), and localized (60.4%; n=2180). The all-time metastasis rate reached 31.4% (n=1131). The lowest mean survival was in those with distant metastasis (P=0.039). Age groups, marital status, tumor morphology, place of residency, and grade were not proven to significantly influence survival. Conclusion: The high metastasis rate and evidence of a greater incidence of newly diagnosed metastatic PCa indicate that the idea of select screening for certain high-risk populations is not farfetched. The authors encourage the promotion of awareness regarding PCa risk factors and screening to optimize prognosis and minimize late presentations and high metastasis rates.

Pediatric Anesthesia Exposure: Decoding Its Neurodevelopmental Implications and Navigating the Nuances.

General anesthesia is fundamental in pediatric medical interventions, but its potential neurodevelopmental impact on children has raised concerns, necessitating a thorough investigation. This systematic review aimed to assess the association between pediatric anesthesia exposure and neurodevelopmental outcomes, focusing on dosage effects and identifying high-risk groups. The study involved an extensive literature search across PubMed, Medline, and Google Scholar, selecting 40 relevant studies from an initial pool of 2,000, based on inclusion criteria that focused on children under 18 years exposed to anesthesia, excluding those with major comorbidities or perioperative physiological insults. It was observed that while a single exposure to anesthesia had minimal impact on general neurodevelopment, repeated or prolonged exposures posed greater concerns. Despite these findings, the study identified gaps in certain areas like adaptive behavior and sensory cognition due to limited data. The conclusion drawn is that although the evidence on anesthesia-induced neurotoxicity in children remains inconclusive, the implications of pediatric anesthesia exposure are significant enough to warrant careful consideration by healthcare professionals, who should balance the procedural benefits against the risks. This study also calls for future research to standardize methodologies and employ consistent, validated neurodevelopmental measurement tools.

The hidden unicuspid: Recurring aortic stenosis post-valvuloplasty from a unicuspid aortic valve masquerading as bicuspid.

Unicuspid aortic valves (UAV) account for 0.2 % of cardiac valvular disorders and present with early-onset aortic stenosis (AS) during adolescence or early adulthood. We present a case of a 17-year-old male with recurring AS. He was diagnosed with bicuspid aortic valve (BAV) two years previously and treated with balloon valvuloplasty, which relieved symptoms before that. Multimodality imaging work-up revealed the precise morphology of UAV, consistent with the surgical findings. The patient received a St. Jude mechanical valve (St Paul; MN, USA) which resolved his symptoms. A thorough radiologic evaluation is therefore required for the accurate diagnosis of UAVs. While 2-dimensional (2D) transthoracic echocardiography (TTE) often constitutes the initial modality for evaluating UAVs, 3D-TTE, transesophageal echocardiography, and cardiac computed tomography are used as confirmatory diagnostic tools. Balloon valvuloplasty reports good outcomes in BAV but is associated with an increased rate of symptom recurrence, repeated surgical procedures, and higher mortality in UAVs, underscoring the importance of an accurate pre-operative diagnosis. Learning objectives: 1.Unicuspid aortic valve (UAV) should be considered in the differential diagnosis of severe aortic stenosis during childhood.2.3D-transthoracic echocardiogram, transesophageal echocardiogram, and cardiac computed tomography (CT) can confirm the diagnosis of a UAV.3.Cardiac CT can additionally assess for accompanying abnormalities of the great vessels in UAV patients.4.Balloon valvuloplasty reports good outcomes in bicuspid aortic valve but is associated with an increased rate of symptom recurrence in UAV patients.

Prostatic adenocarcinoma with transitional cell features among the Saudi Arabian population: a registry review.

Prostate cancer is the third leading cause of death from cancer among American men. Acinar adenocarcinoma is the most common form of prostate cancer; however, there are several nonacinar adenocarcinoma variants, such as transitional cell carcinoma of the prostate and ductal adenocarcinoma. Materials and Methods: A retrospective cohort study was conducted on all Saudi patients diagnosed with adenocarcinoma of the prostate with transitional cell features. The data was collected from the Saudi Cancer Registry, which collects tumor data from all private, military, and Health Ministry hospitals in Saudi Arabia through five regional offices. Results: Out of 3608 patients, only 16 (0.44%) had adenocarcinoma with transitional cell features. All the tumors under investigation were malignant and constituted. Only 6.2% of the tumors were well-differentiated, 43.8% were moderately differentiated, and 50.0% were poorly differentiated. Among the included patients, 56.3% of the patients (n=9) died. There were no significant factors associated with death among patients, including the demographic and tumor-related variables. Conclusion: To the authors' knowledge, this is the first study describing the prevalence of adenocarcinoma with transitional cell features and its characteristics in Saudi Arabia. The authors have demonstrated that this rare subtype may be more prevalent than what was originally believed. It is necessary for future studies to assess the effectiveness of various treatment modalities to combat it. Furthermore, identifying risk factors - if any - may be crucial in the prevention of its development among men worldwide.

An unusually high prevalence of isolated prostatic ductal adenocarcinoma among Saudi patients: A registry-based study.

Objective: We conduct a secondary analysis on the demographics, tumor characteristics, survival, and risk factors for mortality among patients with prostatic ductal adenocarcinoma (PDA) in the Kingdom of Saudi Arabia (KSA). Methods: This is a registry-based retrospective study that included all patients diagnosed with prostate cancer in the KSA. The data were collected from the Saudi Cancer Registry, which collects tumor data from all private, military, and health ministry hospitals in Saudi Arabia through five regional offices. Results: Among 3607 prostate cancer patients detected during the specified period, 209 (5.8%) had ductal adenocarcinoma. The median interquartile range age of patients was 72.0 years (64.0-78.0). Adenocarcinoma lesions were malignant among all the patients. Grade III tumors were most frequently apparent lesions (61.2%), followed by Grade II tumors (26.3%), Grade I tumors (7.2%), and Grade VI tumors (5.3%). A total of 33 patients died, representing 15.8% of the whole sample. The 1-year survival rate was 78.1%. More than a third of patients who were residing in the Western region deceased (38.0%), whereas no deaths were reported in other regions with a statistically significant difference based on regions (P < 0.001). Conclusion: To the best of our knowledge, this is the first registry-based study to investigate PDA in the KSA; these efforts were done to further understand this deadly condition and to further enhance patient care in the KSA.

Pleural effusion due to lymphangiomatosis and the role of sirolimus: A case report.

Introduction: Lymphangiomatosis is a rare abnormal proliferation of lymphatic vessels involving multiple organs like the brain, lung, heart, spleen, liver, and bones. Lymphangiomas constitute 5.6% of all benign tumors in infancy and adulthood. Case presentation: We report a case of a young lady who presented with constitutional symptoms and progressive dyspnea. Her medical history is significant for muco-cutaneous albinism, diffuse hemangiomas of the bone and viscera, and consumptive coagulopathy status post-splenectomy. After initial investigations, she was found to have right-sided pleural effusion. Pleural fluid analysis indicated chylothorax. She had multiple drainages of the pleural fluid done, and afterward, ligation of the right thoracic duct was performed with a trial of sirolimus, which improved her chylothorax. Clinical discussion: Several case reports have reported positive outcomes with sirolimus in the treatment of lymphangiomatosis. However, larger controlled studies are needed to confirm these findings. Conclusion: Sirolimus is promising as a medical treatment for diffuse pulmonary lymphangiomatosis.

Giant staghorn stone causing inferior vena cava compression: a novel case report.

Staghorn calculi (SC) are defined as large kidney stones that fill the renal pelvis and at least one renal calyx. They represent 10-20% of all renal stones in developing countries and require prompt diagnosis and management. Massive SC (over 5 cm) are treated exclusively via open surgery, despite percutaneous nephrolithotomy (PCNL) being the gold standard treatment for large stones. Descriptions of PCNL for massive SC are very limited in the literature. Case Presentation: We report a case of a 63-year-old male who presented with chronic abdominal pain, hepatosplenomegaly, and normal renal function. He was later diagnosed with polycythemia vera. Computed tomography of the abdomen revealed massive, bilateral staghorn stones measuring 7.3×5.5 cm and 1.8×4.5 cm on the right and left, respectively. Additionally, the right stone was found to be compressing the inferior vena cava (IVC). The patient was promptly scheduled for right-sided PCNL and the target of 80% stone fragmentation was successfully attained. Discussion: We present the first case of a stone of such size in the Middle East, as well as the first known case of a renal stone compressing the IVC. Unlike previous reports, the stone was successfully fragmented via PCNL - a procedure that has not been described for stones of such size. Conclusion: This report highlights that ultrasound-guided PNCL without any other intervention is sufficient for the successful treatment of giant SC. Greater research is needed on the potential utility of using ultrasound-guided PCNL for the fragmentation of stones sized over 5 cm.

Navigating the Spectrum: Atypical Pulmonary Involvement in Immunoglobulin G4-Related Disease.

Immunoglobulin G4-related disease (IgG4-RD) is a systemic condition known to affect multiple organ systems. While its manifestations are diverse, pulmonary involvement, especially of the pleura, remains less common. We report the case of a 99-year-old Saudi male with a medical history of diabetes mellitus, chronic kidney disease, and hypertension. He presented with dyspnea and syncope, with radiological findings revealing pleural effusion and a mass in the right hemidiaphragm. Laboratory investigations highlighted elevated serum IgG4 levels, and histopathological evaluation confirmed the diagnosis of IgG4-RD. Notably, the patient's thoracic histopathology differed from typical IgG4-RD presentations, emphasizing the variability of the disease. This case underscores the significance of recognizing IgG4-RD as a potential cause of unexplained pleural effusion. It also highlights the need for a comprehensive diagnostic approach, integrating laboratory values, histopathological findings, and clinical context. Given the potential variability in thoracic IgG4-RD histopathology, clinicians should maintain a heightened awareness of this condition to avoid missed diagnoses.

A systematic review of trials currently investigating therapeutic modalities for post-acute COVID-19 syndrome and registered on WHO International Clinical Trials Platform.

BACKGROUND: Post-acute COVID-19 syndrome (PACS) is a well-recognized, complex, systemic disease which is associated with substantial morbidity. There is a paucity of established interventions for the treatment of patients with this syndrome. OBJECTIVES: To systematically review registered trials currently investigating therapeutic modalities for PACS. DATA SOURCES: A search was conducted up to the 16 September, 2022, using the COVID-19 section of the WHO Internal Clinical Trials Registry Platform. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: Interventional clinical trials of any sample size examining any therapeutic modality targeting persistent symptoms among individuals after diagnosis with COVID-19. METHODS: Data on trial characteristics and intervention characteristics were collected and summarized. RESULTS: After screening 17 125 trials, 388 trials, from 42 countries, were eligible. In total, we had 406 interventions, of which 368 were mono-therapeutic strategies, whereas 38 were intervention combinations. Among 824 primary outcomes identified, there were >300 different outcomes. Rehabilitation was the most employed class of intervention in 169 trials. We encountered 76 trials examining the pharmacological agents of various classes, with the most common agent being colchicine. Complementary and alternative medicine encompassed 64 trials exploring traditional Chinese medicine, Ayurveda, homeopathic medications, naturopathic medications, vitamins, dietary supplements, and botanicals. Psychotherapeutic and educational interventions were also employed in 12 and 4 trials, respectively. Other interventions, including transcranial direct current stimulation, transcutaneous auricular vagus nerve stimulation, general electrical stimulation, cranial electrotherapy stimulation, various stem cell interventions, and oxygen therapy interventions, were also employed. CONCLUSION: We identified 388 registered trials, with a high degree of heterogeneity, exploring 144 unique mono-therapeutic interventions for PACS. Most studies target general alleviation of symptoms. There is a need for further high-quality and methodologically robust PACS treatment trials to be conducted with standardization of outcomes while following WHO's recommendation for uniform evaluation and treatment.

Classical Seminoma With Secondary Undescended Testis in an Elderly Patient: An Incidental Finding With a Penile Fracture.

Cryptorchidism is a common condition among children; however, it is rare in adults and is associated with an increased risk of malignancy. The development of secondary undescended testes is recognized as a complication following inguinal surgeries such as hernia repair and orchidopexy. Herein, we describe the case of a 64-year-old male with a known past surgical history of right indirect inguinal hernia repair complaining of penile swelling. The patient was diagnosed with a penile fracture, and a genital examination further revealed a right undescended testis. The patient underwent penile fracture repair and right orchiectomy. Histopathology examinations showed classic seminoma. These findings show that the position of each testis should always be documented before, during, and after inguinal hernia repair due to the increased risk of undescended testis. Histopathological confirmation is necessary for such patients so that malignancy can be identified in its early stages and cured subsequently.

Understanding COVID-19 Vaccines Today: Are T-cells Key Players?

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has heavily mutated since the beginning of the coronavirus-2019 (COVID-19) pandemic. In this regard, the so-called variants of concern (VOCs) feature mutations that confer increased transmissibility and evasion of antibody responses. The VOCs have caused significant spikes in COVID-19 cases, raising significant concerns about whether COVID-19 vaccines will protect against current and future variants. In this context, whereas the protection COVID-19 vaccines offer against the acquisition of infection appears compromised, the protection against severe COVID-19 is maintained. From an immunologic standpoint, this is likely underpinned by the maintenance of T-cell responses against VOCs. Therefore, the role of T-cells is essential to understanding the broader adaptive immune response to COVID-19, which has the potential to shape public policies on vaccine protocols and inform future vaccine design. In this review, we survey the literature on the immunology of T-cell responses upon SARS-CoV-2 vaccination with the current FDA-approved and Emergency Use Authorized COVID-19 vaccines.

A Rare Presentation of a True Intra-articular Lipoma: A Case Report and Review of Imaging Findings.

This report describes the unique case of an intra-articular lipoma in a 34-year-old male. The patient presented with a history of chronic knee pain associated with an intermittent sensation of the knee giving way. Physical examination and initial radiographic imaging were unremarkable. Magnetic resonance imaging (MRI) revealed a 9.2 x 6.7 mm ovoid mass posterior to the posterior cruciate ligament (PCL) exhibiting hyperintense signals on T1-weighted images and intermediate-to-high intensity signals on T2. On subsequent proton density fat suppression sequences, the mass demonstrated homogenous signal suppression and was confirmed as being a lipoma. To the best of our knowledge, this is only the second reported case of an intra-articular lipoma arising posterior to the PCL. Intra-articular lipomas, albeit rare, should be considered in the differential diagnosis for chronic knee pain with associated joint motion abnormalities. MRI remains the gold standard in imaging intra-articular soft tissue pathology and should be the study of choice in differentiating intra-articular lipomas from similar conditions such as pigmented villonodular synovitis and lipoma arborescens.

Describing the Myths and Misconceptions Regarding COVID-19 Vaccines Among the Population of the Kingdom of Saudi Arabia.

Objectives This study aims to describe the common myths and misconceptions in addition to the perception and attitudes toward coronavirus disease 2019 (COVID-19) vaccines in the Saudi Arabian community. Methods This is a cross-sectional study that included adults (18 years and older) residing in the Kingdom of Saudi Arabia. Participants were asked to complete an online survey that evaluated their perception and attitudes toward the available COVID-19 vaccines in Saudi Arabia. Statistical comparison between two groups and more was done using chi-square, independent t-test, and one-way ANOVA. Results A total of 471 responses were analyzed with a majority (83.2%) believing that vaccinations are important. The vaccine preferred among the Saudi Arabian population was Pfizer (65.4%). More than half of our respondents (54.8%) strongly agreed that COVID-19 vaccines can reduce the severity of the COVID-19 infection. Respondents in the healthcare sector were significantly more likely to have a more positive view on vaccines compared to those in non-healthcare sectors (p < 0.001). Conclusion The Saudi Arabian population has shown substantial awareness about COVID-19 vaccines; however, public health officials need to further increase awareness measures on COVID-19 vaccines to limit myths and misconceptions, especially among certain populations that are more prone to it.
