[Genetic hypothesis involving Haglund's syndrome and its association with ankylosing spondylitis: case report]. / L'hypothèse génétique de la maladie de Haglund, et son association avec la spondyloarthrite ankylosante: à propos d'un cas.

Haglund´s syndrome is characterized by osterosuperior calcaneal exostosis which irritates the Achilles tendon and manifests mainly as posterior talalgia. We here report the case of a 28-year-old woman on follow up for ankylosing spondylitis. Her mother was on follow up for the same systemic disease, and one of her maternal aunts had undergone surgery due to Haglund's syndrome. Patient's delay led to incorrect diagnosis as talagia was considered by physicians as a consequence of her system disease. The patient did not improve under medical treatment. Surgery outcome was satisfactory. This study raises a hypothesis about the genetic and hereditary character of Haglund's syndrome and its relationship with treatment response.

Pairwise Identity Verification via Linear Concentrative Metric Learning.

This paper presents a study of metric learning systems on pairwise identity verification, including pairwise face verification and pairwise speaker verification, respectively. These problems are challenging because the individuals in training and testing are mutually exclusive, and also due to the probable setting of limited training data. For such pairwise verification problems, we present a general framework of metric learning systems and employ the stochastic gradient descent algorithm as the optimization solution. We have studied both similarity metric learning and distance metric learning systems, of either a linear or shallow nonlinear model under both restricted and unrestricted training settings. Extensive experiments demonstrate that with limited training pairs, learning a linear system on similar pairs only is preferable due to its simplicity and superiority, i.e., it generally achieves competitive performance on both the labeled faces in the wild face dataset and the NIST speaker dataset. It is also found that a pretrained deep nonlinear model helps to improve the face verification results significantly.

Palmar dislocation of scaphoid and lunate.

A palmar dislocation of scaphoid and lunate is uncommon. We have found only 19 reported cases in the literature. We reported a simultaneous, divergent dislocation. The closed reduction followed by percutaneous pinning has given a good result without avascular necrosis of any carpal bone.
