ChatGPT: A useful tool for teaching orthopedic trauma to residents

As a practicing orthopedic surgeon and educational deputy in the orthopedic ward, I have witnessed challenges teaching complex surgical procedures and managing orthopedic trauma patients to residents in real-time. However, the advancement of technology has dramatically accelerated the learning process. During Covid-19, we have benefited from online teaching and case discussions using WhatsApp and received many positive feedbacks from residents and faculties. Speaking of the new technological assets, one particular tool that has proven to be very effective for educational purposes is ChatGPT

Orthopedic oncology residency education, how broad and how deep?

Orthopedic residency training has long been an area of active research and discussion, and as the knowledge and concepts in subspecialties evolve, it is crucial to investigate the implications of these advancements in the musculoskeletal oncology field. It is important to note that the acquisition of surgical skills and scientific knowledge from orthopedic texts alone is not sufficient in this area. Orthopedic residents must also acquire multidisciplinary communication and leadership skills, as well as the mental capacity to make sound clinical decisions. Therefore, this commentary highlights the importance of assessing whether the current curriculum provides adequate preparation for residents’ future careers, despite the fact that the expansion of subspecialties in orthopedic education has undoubtedly enhanced the depth of knowledge and concepts in the field. In addition, orthopedic residents must adopt an open-minded and scientific approach toward orthopedic oncology, which has unique principles. Moreover, it is crucial that general orthopedic surgeons have the necessary skills to manage patients and know when to refer them. By exploring these issues, we hope to continually contribute to ongoing discussions about how to improve orthopedic residencyeducation

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

Gorham–Stout syndrome, the challenge in diagnosis and unique in treatment: a case report

Abstract Background Gorham–Stout disease is a rare condition with fewer than 400 reported cases in the literature. The presentation of Gorham–Stout disease varies on the basis of location, extent, fracture, and accompanying symptoms. It lacks a specific histopathological appearance but is characterized by vascular changes and the absence of cellular atypia. Case presentation This article presents a case study of a 16-year-old Persian boy with an entire femur with Gorham–Stout disease, highlighting the difficulties in managing this condition. The lack of a clear diagnosis resulted in prolonged procedures, delayed medical treatments, and ultimately required total femoral replacement with an endoprosthesis. Conclusion It is important to note that raising awareness of this disease and its potential complications can facilitate timely and appropriate treatment for patients presenting in the early stages of the disease

Mortality following proximal femoral fractures in elderly patients: a large retrospective cohort study of incidence and risk factors

Abstract Background Global prevalence of osteoporosis and fragility fractures is increasing due to the aging population. Proximal femoral fractures are among the most common orthopedic conditions in elderly that significantly cause health deterioration and mortality. Here, we aimed to evaluate the mortality rates and risk factors, besides the functional outcomes after these injuries. Methods In a retrospective cohort study, all patients admitted with a femoral neck or intertrochanteric fracture between 2016 and the end of 2018 were enrolled in this study. Medical records were reviewed to include patients over 60 years of age who had a proximal femoral fracture and had a complete medical record and radiographs. Exclusion criteria included patients with pathological fractures, cancer under active treatment, follow-up loss, and patient access loss. Demographic and clinical features of patients alongside the details of fracture and patient management were recorded and analyzed. In-hospital and post-discharge mortalities due to included types of fractures at one and 12 months were the primary outcome. Modified Harris Hip Scores (mHHS) was the measure of functional outcome. Results A total of 788 patients including 412 females (52.3%) and 376 males (47.7%) with a mean age of 76.05 ± 10.01 years were included in this study. Among patients, 573 (72.7%) had an intertrochanteric fracture, while 215 (27.3%) had a femoral neck fracture, and 97.1% of all received surgical treatment. With a mean follow-up of 33.31 months, overall mortality rate was 33.1%, and 5.7% one-month and 20.2% 12-months rates. Analysis of 1-month mortality showed a significant mortality difference in patients operated after 48 h of fracture (p = 0.01) and in patients with American Society of Anesthesiologists (ASA) scores of 3–4 compared to ASA scores of 1–2 (p = 0.001). One-year mortality data showed that the mortality rate in femoral neck fractures was lower compared to other types of fracture. Surgical delay of > 48 h, ASA scores of 3–4, and treatment by proximal femoral plate were associated with shorter survival. The overall mean mHHS score was 53.80 ± 20.78. Conclusion We found several risk factors of mortality, including age ≥ 80 years, a > 48-hour delay to surgery, and pre-operative ASA scores of 3–4 in patients with proximal femoral fracture. Furthermore, the use of a proximal femoral plate was a significant risk factor for mortality and lower mHHS scores
