Patients receiving ICI should be monitored for thyroid dysfunction. A case of PD-1 inhibitor-induced thyroid function test (TFT) interference has been reported (2) and having noted discordant results, we undertook a preliminary assessment of the extent of such ICI-related TFT interfe...

We present a difficult case of pituitary thyroid hormone resistance (PTHR) in a 6 year old girl. She presented at the age of 22 months with chronic cough, diarrhoea, failure to gain weight and gross motor delay. She was also noted to be hyperactive and clumsy with poor co-ordination.
