Comparison of Continuous versus Pulsed Mode in Accelerated Corneal Collagen Cross-linking for Keratoconus.

Purpose: To compare efficacy and safety between the two modes of energy delivery-pulsed and continuous, in accelerated corneal collagen cross-linking (KXL) to stop the keratoconus advancement through topographical, visual, and refractive endpoints.

Methods: It was a prospective, comparative, randomized, interventional trial. Patients with bilateral progressive keratoconus were subjected to pulsed mode KXL (P-KXL) in the right and continuous mode KXL (C-KXL) treatment in the left eye.

To study ultrasound and chest X-ray findings and their role in the diagnosis of dengue fever in children.

Introduction: Dengue fever is a fatal viral illness affecting almost all age groups and is seen in almost all tropical countries. Ultrasonography (USG) can be a useful tool for the assessment and diagnosis of dengue fever.

Objectives: The study aimed to evaluate X-ray and ultrasound findings in children with dengue fever.
