A review on optimization of Wilms tumour management using radiomics.

Background: Wilms tumour, a common paediatric cancer, is difficult to treat in low- and middle-income countries due to limited access to imaging. Artificial intelligence (AI) has been introduced for staging, detecting, and classifying tumours, aiding physicians in decision-making. However, challenges include algorithm accuracy, translation into conventional diagnosis, reproducibility, and reliability.

Community Awareness and Knowledge About Precocious Puberty in Riyadh City, Saudi Arabia.

Background Puberty is the process of physical maturation where an adolescent reaches sexual maturity and becomes capable of reproduction. On average, puberty typically begins between 8 and 13 years old in females and 9 and 14 years old in males. The traditional definition of precocious puberty is the development of secondary sexual characteristics before eight years of age in girls and nine years in boys.

Strengthening laboratories in response to outbreaks in humanitarian emergencies and conflict settings: Results, challenges and lessons from expanding PCR diagnostic capacities for COVID-19 testing in Yemen.

Background: When the COVID-19 pandemic was declared, Yemen, a country facing years of conflict had only one laboratory with PCR testing capacity. In this article, we describe the outcome of the implementation of molecular based diagnostics platform in Yemen and highlight the key milestones the country went through to increase access to testing for its populations residing in a geographically vast and politically divided country.

Methods: A retrospective assessment of COVID-19 laboratory response activities was done detailing the needs assessment process, timelines, geographical coverage, and outcomes of the activities.

Testicular Torsion in the Undescended Testis of a Four-Year-Old: A Delayed Diagnosis.

In this report, we discuss the case of a four-year-old boy known to have global developmental delay (GDD) and infantile spasm. The child was brought to the emergency department (ER) with a tender inguinal swelling and fever. Notably, there was no previous indication of an undescended testicle (UDT), and the scrotum was not examined in the ER initially.

Wide-field-of-view optical detectors for deep ultraviolet light communication using all-inorganic CsPbBr perovskite nanocrystals.

Optical wireless communication (OWC) links suffer from strict requirements of pointing, acquisition, and tracking (PAT) between the transmitter and receiver. Extending the narrow field-of-view (FoV) of conventional light-focusing elements at the receiver side can relax the PAT requirements. Herein, we use all-inorganic CsPbBr nanocrystals (NCs) to extend various optical concentrators' FOV to 60°, regardless of the original FOV values of the concentrators.
