[THYROID HEMIAGENESIS: A CASE REPORT].

Introduction: Thyroid hemiagenesis is a rare congenital anomaly characterized by the absence of one thyroid lobe and the isthmus. This case report presents a 4-year-old girl with a history of prematurity. Incidentally, during a routine ultrasound evaluation of the neck, thyroid hemiagenesis was detected along with the presence of normal lymph nodes.

Predicting response to pembrolizumab in metastatic melanoma by a new personalization algorithm.

Background: At present, immune checkpoint inhibitors, such as pembrolizumab, are widely used in the therapy of advanced non-resectable melanoma, as they induce more durable responses than other available treatments. However, the overall response rate does not exceed 50% and, considering the high costs and low life expectancy of nonresponding patients, there is a need to select potential responders before therapy. Our aim was to develop a new personalization algorithm which could be beneficial in the clinical setting for predicting time to disease progression under pembrolizumab treatment.
