Lenvatinib therapy is well tolerated and demonstrated clinical activity in children with advanced PTC. Lenvatinib should be considered in children with PTC that is refractory or not amenable to conventional management.
Case 1: A 2-year-old North African boy was brought to our hospital because of absent teeth development and failure to walk. The patient appeared to be well nourished and content. His body mass index was 19.1 kg/m 2 (90th percentile), he was 86 cm long (25th percentile) and he weighed 13.6 kg (75th percentile). Palpation of the patient's extremities revealed prominent, flared distal radii, humeri and femurs. The result of a total serum calcium test was 1.4 (normal 2.1-2.6) mmol/L. Case 2: A 6-year-old boy presented with hard, nodular skin lesions on his torso. The patient was short (< 3rd percentile), and he had mild developmental delays and obesity. Because a skin biopsy demonstrated subcutaneous calcification, his total serum calcium level was measured and found to be 1.3 mmol/L. Case 3: A 12-year-old boy presented with concerns about intermittent numbness of his extremities. He reported having had 1 episode where he "lost control" of his right leg and fell. A CT scan showed calcification of the basal ganglia. His total serum calcium level was 1.5 mmol/L.
The design was a retrospective description of the flow of information and, ultimately, action towards the goal of timely treatment of CH. Cases were defined as ones in which the infant was born in Alberta between January 1, 2005 and May 31, 2008, and found to have a newborn screening TSH >50 mU/L. A timeframe was selected that was considered recent and practical.Cases were identified from the NMS database. Data accompanying each child's positive screen included health number, birth date,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
