Purpose: The stability of the tear film is crucial for maintaining good ocular health. Its assessment provides valuable insights into paediatric eye conditions. This study investigates the stability of the tear film in children and its association with predictive factors such as age and sex, for a better understanding of tear film dynamics in a paediatric population.

Article Synopsis
  • The cornea is essential for protecting the eye, and central corneal thickness (CCT) measures its thickness from the front to the back.
  • CCT is crucial for accurate intraocular pressure measurements, assessing corneal health, and planning refractive surgeries.
  • Understanding the various factors that affect CCT can improve diagnostic and treatment approaches in eye care.

Article Synopsis
  • The study examined the quality of life (QoL) of women with cervical cancer, emphasizing the importance of considering sexual health amid societal taboos surrounding the topic.
  • It compared long-term QoL outcomes among different treatment methods: chemotherapy/radiotherapy/brachytherapy, hysterectomy alone, and hysterectomy with radiotherapy, involving 131 patients.
  • Results indicated that patients who had isolated hysterectomy reported better QoL scores than those undergoing more aggressive therapies, highlighting the need for comprehensive care that includes addressing sexual concerns in survivorship.

Color supports object identification. However, two objects that differ in color under one light can appear indiscriminable under a second light, a phenomenon known as illuminant metamerism. Past studies evaluated the frequency of illuminant metamerism only under single, uniform illuminants.

The perceived color of human skin is the result of the interaction of environmental lighting with the skin. Only by resorting to human skin spectral reflectance, it is possible to obtain physical outcomes of this interaction. The purpose of this work was to provide a cured and validated database of hyperspectral images of human faces, useful for several applications, such as psychophysics-based research, object recognition, and material modeling.
