BACKGROUND Testicular mixed germ cell tumors (GCTs) represent a spectrum of malignancies that differ in terms of histopathology, clinical complications, and overall outcome. A variety of aggressive combinations containing different histological types have been described among such testicular tumors. However, a histopathology characterized by a combination of teratoma and choriocarcinoma, as seen in this case, in which the teratomatous component shows a secondary transformation to chondrosarcoma, is considered very rare.

Nano-emulsion consists of a dispersion of oil droplets sizing below 200 nm, in aqueous continuous phase, and generally stabilized by low-molecular-weight surfactants. These stable nano-carriers are able to encapsulate and transport lipophilic molecules poorly soluble in water. However, the question on the leakage and release mechanisms of an active pharmaceutical ingredient, from oil nano-droplets to an acceptor medium has not been clearly addressed.

Introduction: The incidence of childhood acute lymphoblastic leukemia (cALL) varies between countries likely as a result of competing risks including infections, access-to-care, socioeconomic influences, and/or ethnicity. However, little is known about disease burden in high-income Arab countries offering free-of-charge healthcare. The hypothesis was that, due to population characteristics (young age, high fertility and parental consanguinity rate), the incidence of cALL in Saudi Arabia is equal or higher than that observed in high-income Western countries.

Article Synopsis
  • The study focuses on oncologists' awareness and opinions about virtual management of cancer care during the COVID-19 pandemic, particularly in rural areas affected by curfews.
  • An electronic survey gathered responses from 222 oncologists in Gulf and Arab countries, highlighting their familiarity with virtual clinics and the challenges they face, such as lack of physical exams and IT support.
  • While many oncologists preferred using virtual methods for certain treatments like hormonal therapy, a substantial number were reluctant to prescribe chemotherapy or immunotherapy virtually.

Background: There are a limited number of studies that address non-neutropenic fever episodes in children with cancer, and no standard approach exists.

Method: We opt to retrospectively analyze the efficacy of the current clinical approach for management of non-neutropenic fever episodes and the associated risk factors among children with cancer at the Princess Noorah Oncology Center from May 2016 through December 2017.

Results: A total of 480 non-neutropenic fever episodes were identified in 131 children, of which 62 episodes were triaged as high-risk non-neutropenic fever and 418 as low-risk non-neutropenic fever.

Two known polyphenols named apigenin 7-O-β-d-glucopyranoside (S1) and querctine-3-O-glucoside (S2), along with another two new compounds apigenin 4'-geranyl-8-glucopyranosyl-7-O-α-glucopyranoside (S3) and apigenin 4'-pernyl-8-glucopyranosyl -7-O-α-glucopyranoside (S4), were isolated from the leaves of Cupressus sempervirens. Structure elucidation of the isolated polyphenols was established on the basis of detailed spectroscopic analysis like 1D and 2D NMR analyses including H NMR, C NMR, COSY, DEPT, HMQC, UV, and Electron Spray Ionization Mass Spectroscopy (ESI-MS). Density Functional Theory (DFT) of computational, Petra/Osiris/Molinspiration (POM), and docking analyses methods were applied in the structural validation of new isolated compounds.

Many patients with sickle cell disease (SCD) need surgical management during their lifetime. The best approach for preoperative transfusion in SCD is still to be determined. In this single-center retrospective study, we included HBSS/HBS-Beta-thalassemia patients younger than 16 years of age who underwent surgery between January 2008 and July 2019.

The purpose of this study was to develop Pickering water-in-oil nano-emulsions only stabilized by Eudragit RL100 nanoparticles (NPs), in order to increase the nano-emulsion stability and create a barrier to improve the drug encapsulation and better control the drug release. The first part of this study was dedicated to investigating the nano-emulsion formulation by ultrasonication and understanding the interfacial behavior and role of NPs in the stabilization of the water/oil interface. The focus was on the surface coverage in the function of the formulation parameters (volume fractions) to disclose the extents and limitations of the process.

Objectives: To study the prevalence of middle mesial and middle distal canals in permanent mandibular molars in Egyptian subpopulation using micro-computed tomography.

Materials And Methods: Two hundred and forty extracted mandibular permanent molars of Egyptian patients were scanned using micro-computed tomography, then the images were reconstructed to allow for the detection of the middle mesial (MM) and middle distal (MD) canals of the molars examined. The path of each extra canal was studied to determine the configuration of each canal.

Background: Transdermal drug delivery has many advantages compared to other routes. However, the barrier function of the stratum corneum limits the use of the skin as an administrative route for medications. Different methods were investigated to alter the barrier function of the stratum corneum and it was found that applying different ultrasound waves could enhance the skin's permeability.

King Abdullah Medical City, Makkah, Saudi Arabia.

. Giant lipomas, which are greater than 10 cm, are rare, cosmetically unacceptable, and deteriorate the quality of daily living. Removal of giant abdominal lipomas either by liposuction, excision, or both, can lead to the formation of a loose, pendulous drooping abdomen, and abdominal wall laxity, which is aesthetically displeasing.
