Scalp Metastasis From Renal Cell Carcinoma: A Rare Case With Rapid Progression.

Renal cell carcinoma (RCC) is a common renal malignancy that frequently metastasizes, though cutaneous metastasis, particularly to the scalp, is rare and generally indicates a poor prognosis. We report a case of scalp metastasis from RCC in a 69-year-old man who presented with unexplained weight loss and painless hematuria. Imaging revealed a 12-cm renal mass with adrenal, pulmonary, and scalp metastases.

Evaluation of Zygomaticomaxillary Complex Fractures with Gillies Approach in Al-Baha Region of Saudi Arabia: A Cohort Study.

Background: The aim of this study was to evaluate the accuracy of the degree of fracture reduction after open reduction and internal fixation of Zygomaticomaxillary Complex (ZMC) fractures in the Saudi population of the Al-Baha region, using Gillies approach. Further comparison with preoperative and postoperative standardized computed tomography (CT) views with the calculation of residual deformity percentage, which remained after the ZMC rehabilitation.

Methods: A 5-year retrospective CT-based study on preoperative and postoperative axial CT scans of 46 male patients with ZMC fractures.

Study of Streptococcus mutans in Early Biofilms at the Surfaces of Various Dental Composite Resins.

Background: Biofilm deposit on the composite restoration is a common phenomenon and bacterial growth follows the deposition. The study aims to evaluate () early biofilm formation on the surfaces of various dental composite resins by using the real-time quantitative polymerase chain reaction (qPCR) technique.

Materials And Methods: Thirty-two discs, where eight discs were in each group of Filtek Supreme Ultra (FSU; 3M, St.

Acute gastroenteritis-related acute kidney injury in a tertiary care center.

Background: Acute gastroenteritis (AGE) can cause acute kidney injury (AKI) via hypoperfusion mechanisms. Early detection of AKI caused by AGE can significantly decrease mortality rates. In Saudi Arabia, studies investigating the association between AGE and AKI are limited; thus, we aimed to fill this knowledge gap.

Tools to Alleviate the Drug Resistance in .

Mycobacterium tuberculosis (), an acid-fast bacillus that causes Tuberculosis (TB), is a pathogen that caused 1.5 million deaths in 2020. As per WHO estimates, another 4.

Clinical Characteristics, Complications, and Predictors of Poor Outcome Among Hospitalized Adult COVID-19 Patients: A Retrospective Cohort Study.

Background Many international studies have reported the outcomes and predictors of coronavirus disease 2019 (COVID-19); however, only a few national studies have reported predictors of poor outcomes among adult hospitalized patients with COVID-19. Therefore, this study aimed to describe the clinical characteristics and complications of COVID-19 and identify predictors of poor outcomes. Methods This was a retrospective cohort study.

Electron Transport Layer Optimization for Efficient PTB7:PCBM Bulk-Heterojunction Solar Cells.

Bulk-heterojunction (BHJ) polymer solar cells have received a great deal of attention mainly due to the possibility of higher power conversion efficiency for photovoltaic applications. Therefore, in this study, relatively novel polymer BHJ solar cells are proposed (ITO/ETL/PTB7:PCBM/PEDOT:PSS/Au) with various electron transport layers (ETL) such as zinc oxysulfide (Zn(O,S)), zinc selenide (ZnSe), and poly[(9,9-bis(3'-((N,N-dimethyl)-N-ethylammonium)-propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)] dibromide (PFN-Br). Here, each ETL material is selected based on the energy bandgap compatibility with ITO as well as the PTB7:PCBM active layer and is based on other physical properties, which are generally required for efficient photovoltaic responses.

Evaluate the Effectiveness of Outpatient Parenteral Antimicrobial Therapy (OPAT) Program in Saudi Arabia: A Retrospective Study.

(1) Background: Outpatient parenteral antibiotic therapy (OPAT) is a well-established and cost-effective measure that improves the efficient use of healthcare resources and increases bed availability. Only limited published data is available to illustrate OPAT implementation and outcomes in Saudi Arabia. The main objective of this study was to evaluate the effectiveness of OPAT in a tertiary center in Saudi Arabia.

Computational Intelligence Approaches in Developing Cyberattack Detection System.

The Internet plays a fundamental part in relentless correspondence, so its applicability can decrease the impact of intrusions. Intrusions are defined as movements that unfavorably influence the focus of a computer. Intrusions may sacrifice the reputability, integrity, privacy, and accessibility of the assets attacked.

Indirect-Neural-Approximation-Based Fault-Tolerant Integrated Attitude and Position Control of Spacecraft Proximity Operations.

In this paper, a neural adaptive fault-tolerant control scheme is proposed for the integrated attitude and position control of spacecraft proximity operations in the presence of unknown parameters, disturbances, and actuator faults. The proposed controller is made up of a relative attitude control law and a relative position control law. Both the relative attitude control law and relative position control law are designed by adopting the neural networks (NNs) to approximate the upper bound of the lumped unknowns.

Classification and Detection of Autism Spectrum Disorder Based on Deep Learning Algorithms.

Autism spectrum disorder (ASD) is a type of mental illness that can be detected by using social media data and biomedical images. Autism spectrum disorder (ASD) is a neurological disease correlated with brain growth that later impacts the physical impression of the face. Children with ASD have dissimilar facial landmarks, which set them noticeably apart from typically developed (TD) children.

Potential Association between the Use of Anabolic Steroids and COVID-19 Infection.

Anabolic androgenic steroids (AASs) are synthetic analogs of testosterone that can affect the immune system. Bodybuilders and sportsmen are at risk of abusing AASs. The aim of this study was to investigate the association between AASs use and coronavirus disease (COVID-19).

Management of Knee Flexion Contracture in a Child With 3MC Syndrome Using Taylor Spatial Frame.

3MC syndrome is a rare genetic disorder inherited through an autosomal recessive inheritance pattern caused by mutations in one of three genes: , , and . High-arched brows, ptosis, blepharophimosis, hypertelorism, cleft lip, cleft palate, developmental delay, hearing loss, abdominal wall defect, and urogenital and skeletal abnormalities are all characteristics. In previous reports, involvement of knee flexion contracture was not known to be one of the 3MC syndrome symptoms.

COVID-19-Related Knowledge and Practices Among Health Care Workers in Saudi Arabia: Cross-sectional Questionnaire Study.

Background: Health care workers are at the front line against COVID-19. The risk of transmission decreases with adequate knowledge of infection prevention methods. However, health care workers reportedly lack a proper attitude and knowledge of different viral outbreaks.
