Ultrasound guided costoclavicular block in pediatric population: A prospective observational study.

Background: The costoclavicular space serves as an alternative approach to the infraclavicular brachial plexus block, and numerous studies in adults have demonstrated promising outcomes for distal upper limb surgery. Blocking the brachial plexus at this level is potentially advantageous because the cords are relatively superficial, located in close proximity to each other and easily identified using ultrasound.

Aims: This study aimed to assess the success rate and feasibility of costoclavicular block in children undergoing unilateral below elbow upper limb surgery.

The autoimmune basis of hypopituitarism in traumatic brain injury: fiction or reality?

Post-traumatic hypopituitarism has remained as an obscured cause of worsening morbidity and mortality in head injury patients. Researchers have for decades been puzzled by the mechanism of pituitary dysfunction in these cases. Amongst other causes like direct injury, vascular injury etc, an immunological basis of hypopituitarism has been suggested in some animal studies as well as human research.
