ABSTRACT
Introduction ChatGPT (OpenAI Incorporated, Mission District, San Francisco, United States) is an artificial intelligence (AI) chatbot with advanced communication skills and a massive knowledge database. However, its application in medicine, specifically in neurolocalization, necessitates clinical reasoning in addition to deep neuroanatomical knowledge. This article examines ChatGPT's capabilities in neurolocalization. Methods Forty-six text-based neurolocalization case scenarios were presented to ChatGPT-3.5 from November 6th, 2023, to November 16th, 2023. Seven neurosurgeons evaluated ChatGPT's responses to these cases, utilizing a 5-point scoring system recommended by ChatGPT, to score the accuracy of these responses. Results ChatGPT-3.5 achieved an accuracy score of 84.8% in generating "completely correct" and "mostly correct" responses. ANOVA analysis suggested a consistent scoring approach between different evaluators. The mean length of the case text was 69.8 tokens (SD 20.8). Conclusion While this accuracy score is promising, it is not yet reliable for routine patient care. We recommend keeping interactions with ChatGPT concise, precise, and simple to improve response accuracy. As AI continues to evolve, it will hold significant and innovative breakthroughs in medicine.
ABSTRACT
Background The demanding nature of neurosurgical practice requires a reliable system for documentation and record-keeping. The cost of electronic health record systems can limit their availability in low- and middle-income countries. That is why less expensive and easily accessible technological alternatives should be sought. In this article, we describe our adopted system for medical record-keeping based on WhatsApp (Meta Platforms, Inc., Menlo Park, CA). Methods In our chain of six clinics, each clinic has its record-keeping WhatsApp group dedicated to sharing medical data of outpatients following up in that specific clinic and of inpatients cared for in hospitals in its area. After each encounter, our surgeons share smartphone-captured pictures of their patients' medical data on the WhatsApp group of the related clinic. The medical data are then categorized and stored by the secretary on the clinic's computer to be accessed at any time for record retrieval. Discussion Our five years of experience with the WhatsApp-based record-keeping system with medical records of 11,729 patients proved to be reliable, cost-effective, user-friendly, and efficient, and it positively impacted patient care. Responsible behavior, security precautions, and regulating policies are essential to protect patient confidentiality. Conclusion Our system can be an inexpensive alternative to the electronic health record system in small healthcare facilities. It can help physicians practicing in low- and middle-income countries to improve medical records documentation, thereby improving patient care. There is a need for policies to regulate the use of instant messaging applications in professional medical communication.
ABSTRACT
Background: Dural sinus thrombosis is considered as a one of the clinical and radiological emergencies that require special attention and high index of suspicion and needs combined effort of both the treating physician and the radiologist to obtain proper diagnosis and subsequently proper management. Objective: The aim of this article was to compare the accuracy of MRV TOF and post contrast MP-RAGE sequences in diagnosis of cerebral sinus venous thrombosis. Methods: After all informed consents were obtained and upon ethical committee approval from the ethical committee in Joradanian Royal medical services in Amman we perform this study as a retrospective study done on 50 patients with cerebral sinus venous thrombosis with 50 pateints control group done at king Hussein medical center in Amman Jordan. Results: The guidelines and regulations of studies conducted in Royal medical services were followed. 68 females and 32 males with age range between 19 and 52 years. All patients underwent brain MRI for evaluation of cerebral sinus thrombosis, all studies were done on seimens skyra 3 Tesla machine with standardized protocol including 2 D TOF MRV, axial T2WI, axial FLAIR, Axial T1, SWI and diffusion weighted images along with 3D MP-RAGE post contrast. Images were reviewed by two well experienced neuroradiologists (Maysoon and Qamar) in separate sessions, each MRI sequence was reported separately without knowing patients name or clinical history. Conclusion: The results for T2 WI, SWI, MRV TOF and MP-RAGE post contrast were reported. We used a confidence level score to standardize the results. Then the results were analyzed using simple statistical methods.
ABSTRACT
BACKGROUND: Craniotomies for resection of neoplastic lesions are at increased risk for surgical site infections (SSIs) as compared to non-neoplastic pathologies. SSIs can be detrimental due to delay in pivotal adjuvant therapies. OBJECTIVE: The purpose of this study was to determine the rate of SSI in primary brain tumors, to analyze risk factors, and to evaluate effectiveness of topical vancomycin in reducing SSIs. METHODS: A retrospective cohort study was conducted at a National Cancer Institutedesignated Comprehensive Cancer Center. Patients with primary brain tumors (n = 799) who were subjected to craniotomy from 2004 to 2014 were included. Patient demographics, tumor characteristics, use of topical vancomycin and clinical outcomes were analyzed. RESULTS: Topical vancomycin was associated with a significantly lower rate of SSI (0.8%) compared to standard care (5%), ( p = 0.00071; OR = 0.15; 95% CI = 0.02 - 0.5). Narcotic use ( p = 0.043; OR = 2.24; 95% CI = 0.96 - 4.81), previous brain radiation ( p = 0.043; OR = 2.08; 95% CI = 1.02 - 4.29), length of hospitalization ( p = 0.01; OR= 1.04; 95% CI = 1.01 - 1.08), and 30 day re-operation ( p = 1.58 ×10 -10; OR = 15.23; 95% CI = 7.06 - 32.71) were associated with increased risk for SSI. CONCLUSION: Topical vancomycin effectively reduced the rate of SSI in patients subjected to craniotomy for primary brain tumor resection. Furthermore, preoperative narcotic use, previous head/brain radiation, length of hospitalization, and 30-day reoperation were associated with increased risk of SSI.
