Intratumoral immune-biomarkers and mismatch repair status in leiyomyosarcoma -potential predictive markers for adjuvant treatment: a pilot study.

Leiomyosarcoma is the second most frequent soft-tissue sarcoma. Tumor lymphocytic infiltration (TIL) and programed cell death ligand-1 (PD-L1) have been associated with prognosis in different malignancies while DNA mismatch-repair deficiency (MMR-D) has been associated with response to check-point inhibitors. In this pilot study, we sought to examine TIL, PD-L1 and mismatch-repair (MMR) protein expression in 11 leiomyosarcoma and its association with outcome as potential biomarkers for adjuvant treatment.

Congenital hypothyroidism with Prader-Willi syndrome.

We report a 1 year-old female patient with severe hypotonia who has congenital hypothyroidism and Prader-Willi syndrome (PWS). At birth she was found to have congenital hypothyroidism caused by an ectopic sublingual thyroid gland and was commenced on thyroid replacement therapy. She continued to have severe motor delay and therefore further diagnostic evaluation was performed.
