Background: The preoperative visit is an appropriate time to educate the patient on anaesthesia. The aim of this study was to determine if a website, as an information source for anaesthesia before the visit to the preoperative assessment clinic (PAC), increases patients' knowledge on anaesthesia.
Methods: A multimedia website was developed containing specific information about anaesthesia relevant to the patient. A questionnaire was developed to measure knowledge gain. Patients were divided into three groups: (i) those who read the existing brochure; (ii) those who looked at the new website; and (iii) a cluster of non-brochure and non-website users: those who did not read the brochure or website but had completed the questionnaire. An anaesthesiologist also informed all three groups during the preoperative visit at the PAC.
Results: Patients visiting the website had a higher educational level than others. A significant increase in knowledge was observed after using the website information compared with the other two groups (P<0.001). The group with higher education levels had higher knowledge gains, and the website independently contributed to the knowledge gain.
Conclusions: A patient-tailored multimedia website is an effective way to support the information provided by the anaesthesiologist in order to inform patients about their upcoming anaesthetic procedure. The use of such a website gives a significant increase in knowledge compared with only spoken information, or spoken information combined with a brochure.

Biomechanical Principles of Spinal Deformity Correction in the Thoracolumbar Spine.
J Am Acad Orthop Surg
January 2025
From the Children's Mercy Hospital, Kansas City, MO (Shaw), Children's Health Ireland at Temple Street, Dublin, Ireland (O'Sullivan), the Department of Mechanical Engineering, Polytechnique Montreal, Montreal, Quebec, Canada (Wang and Aubin), and the Sainte-Justine University Hospital Center, Montreal, Quebec, Canada (Wang and Aubin).
Thoracolumbar spinal deformities are a pervasive condition affecting the adolescent and adult patient population. These deformities represent three-dimensional alterations in the coronal, sagittal, and transverse planes with implication on the local, regional, and global alignment. With continued studies, the importance of the overall correction on long-term outcomes has been established.

The global prevalence of Parkinson's Disease (PD) is on the rise, driven by an ageing population and ongoing environmental conditions. To gain a better understanding of PD pathogenesis, it is essential to consider its relationship with the ageing process, as ageing stands out as the most significant risk factor for this neurodegenerative condition. PD risk factors encompass genetic predisposition, exposure to environmental toxins, and lifestyle influences, collectively increasing the chance of PD development.

University Medical Center Utrecht, Utrecht, The Netherlands.
Background: A pediatric cancer diagnosis is overwhelming and stressful for the whole family. Patient-centered communication during the diagnostic conversation can support medical and psychosocial adaptation to the disease. Treatment of pediatric leukemia has become increasingly complex and requires a specific skillset from clinicians in effectively conveying information to families.

J Pediatr Orthop
January 2025
Department of Pediatric Orthopaedic Surgery, Robert Debré University Hospital, Assistance Publique des Hôpitaux de Paris (AP-HP).
Background: Lower instrumented vertebra (LIV) selection for adolescent idiopathic scoliosis (AIS) with structural lumbar curves (Lenke 3, 5, and 6) remains debated. The iliolumbar angle (ILA) measurement is useful for assessing the lumbosacral junction flexibility. If it is nonreducible, surgeons need to make a difficult choice between a potential "imperfect" L4, associated with a residual lumbosacral curve, or a more distal fusion performed later in life due to poorer functional outcomes.
