The in vivo assessment of the three-dimensional (3D) kinematics of the hip in patients with femoroacetabular impingement (FAI) under weight-bearing conditions has not been previously reported. We evaluated the pre- and postoperative hip kinematics of a 34-year-old man, with a cam-type FAI while squatting, using image-matching techniques with measurement of the rim-neck distance. Post-osteochondroplasty, the α-angle improved from 51.0° to 35.5° and the head-neck offset ratio from 0.04 to 0.23. Coxalgia during squatting disappeared, and the Harris Hip Score improved from 79 to 92 at 1 year post-surgery...

REVIEW
Michael S Gart, Santhanam Suresh, Joshua M Adkinson
Millions of children undergo general anesthesia for surgical procedures each year, the implications of which are not fully understood. Animal models demonstrate neurotoxicity and long-term cognitive impairment following exposure to common general anesthetic agents. However, it is unclear if human brains are affected in a similar fashion and what-if any-the implications on cognitive development may be. Furthermore, it is not known if these effects are additive and if they can be avoided by delaying reconstruction...

INTRODUCTION: Nasal obstruction is a frequent complaint in otorhinolaryngology outpatient clinics, and nasal valve incompetence is the cause in most cases. Scientific publications describing surgical techniques on the upper and lower lateral cartilages to improve the nasal valve are also quite frequent. Relatively few authors currently describe surgical procedures in the piriform aperture for nasal valve augmentation. We describe the surgical technique called pyriform plasty and evaluate its effectiveness subjectively through the NOSE questionnaire and objectively through the rhinomanometry evaluation...
