[A practical algorithm for polydipsia in children].

There is a lack of consent on a clinical diagnostic work-up for children with polydipsia. This can result in a delay in diagnosis in some children and unnecessary investigations in others. We describe three children who presented with polydipsia.

[A boy with cervical focal myositis].

Background: Focal myositis is a rare idiopathic pseudotumour that mostly occurs in the extremities in adults.

Case Description: An 8-year-old boy presented with a few months history of swelling in the neck and fever. Ultrasound investigation revealed an inhomogenous mass consistent with lymphadenitis.

Natural killer T cells in adipose tissue prevent insulin resistance.

Lipid overload and adipocyte dysfunction are key to the development of insulin resistance and can be induced by a high-fat diet. CD1d-restricted invariant natural killer T (iNKT) cells have been proposed as mediators between lipid overload and insulin resistance, but recent studies found decreased iNKT cell numbers and marginal effects of iNKT cell depletion on insulin resistance under high-fat diet conditions. Here, we focused on the role of iNKT cells under normal conditions.
