Clinical Features of Seven COL2A1 Variations in Chinese Children With Type II Collagen Disorders

Acta Paediatrica, Volume 114, Issue 7, Page 1720-1730, July 2025.
ABSTRACT Aim Type II collagen, encoded by the collagen type II alpha 1 (COL2A1) gene, is crucial for the structure of cartilage. This study aims to improve our understanding of Spondyloepiphyseal Dysplasia Congenita (SEDC) caused by mutations in COL2A1. We also aim to evaluate the safety and efficacy of growth hormone (GH) therapy in two SEDC patients.

11. Cervicogenic headache and occipital neuralgia

Pain Practice, Volume 25, Issue 1, January 2025.
Abstract Introduction Cervicogenic headache (CEH) and occipital neuralgia (ON) are headaches originating in the occiput and that radiate to the vertex. Because of the intimate relationship between structures based in the occiput and those in the upper cervical region, there is significant overlap between the presentation of CEH and ON. Diagnosis starts
