Etiology and Related Factors of Postoperative Delirium in Orthopedic Surgery. Clin Orthop Surg. 2019 Sep;11(3):297-301 Authors: Song KJ, Ko JH, Kwon TY, Choi BW Abstract Background: Delirium is a serious complication for elderly patients after orthopedic surgery. The purpose of this study was to assess the etiology and related factors of delirium after orthopedic surgery in Korea. Methods: We retrospectively reviewed the medical records of 3,611 patients over 50 years who had orthopedic surgery. The age of patients (50s, 60s, 70s, and> 80s), type of anesthesia (general, spinal, and local), operation time (more than 2 hours vs. less than 2 hours), surgical site (spine, hip, knee, or others), and etiology (trauma or disease) were compared to determine possible risk factors of delirium after orthopedic surgery. Results: Of 3,611 patients, 172 (4.76%) were diagnosed with delirium after orthopedic surgery. Postoperative delirium occurred in 1.18% in their 50s, 3.86% in their 60s, 8.49% in their 70s, and 13.04% in> 80s (p

ConclusionsAlfaxalone is observed to be more physiologically stable, evoking a more consistent BOLD signal across animals than the co-administration of ketamine and isoflurane. Thus, an alfaxalone-based protocol may represent a better approach for neuroimaging in animal models requiring anesthesia.Graphical abstract

NHS Chief Sir Simon Stevens has today (Saturday) announced that the NHS and its staff will step up action to tackle the climate “health emergency” this year, helping prevent illness, reducing pressure on A&Es, and saving tens of thousands of lives. The initiative follows the launch of the Climate Assembly UK this week, which is discussing how the country can best get to ‘net zero’. Health chief Sir Simon Stevens has today announced three steps the NHS will take during 2020 to tackle this problem.

Authors: Ogawa Y, Ogawa Y Abstract Malignant skin tumors and precancerous lesions have a predilection to be located in the nasal dorsum or sidewall. Although invasive reconstructions have been presented, no simple and suitable method has yet been reported for this area. The flap presented herein, named the lateral nasal advancement flap, is designed on the adjacent lateral region of the sidewall or nasal dorsum and advanced in the medial direction. Two Burow's triangles are removed in the upper and lower portions of the flap: the upper triangle along the nasofacial sulcus and the lower triangle along the nasofacial...

Intrathecal autologous bone marrow (ABM) total nucleated cells transplantation (TNCT) has been reported to be a promising treatment for cerebral palsy (CP) and autistic disorders (AD). Children with CP and AD, are expected to be patients with difficult approach when doing venipuncture or taking them to the operating room. Considering pain and the nature of the procedures, bone marrow collection (BMC) and intrathecal procedures (ITP) must be performed under sedation. For short procedures, sevoflurane can be administrated using a face mask and, propofol, a typical intravenous agent is used for the induction of general anesth...
