PURPOSE: The usage of Chatbots as a kind of Artificial Intelligence in medicine is getting to increase in recent years. UpToDate® is another well-known search tool established on evidence-based knowledge and is used daily by doctors worldwide. In this study, we aimed to investigate the usefulness and reliability of ChatGPT compared to UpToDate in Otorhinolaryngology and Head and Neck Surgery (ORL-HNS). MATERIALS AND METHODS: ChatGPT-3.5 and UpToDate were interrogated for the management of 25 common clinical case scenarios (13 males/12 females) recruited from literature considering the daily observation at the Department of Otorhinolaryngology of Ege University Faculty of Medicine. Scientific references for the management were requested for each clinical case. The accuracy of the references in the ChatGPT answers was assessed on a 0-2 scale and the usefulness of the ChatGPT and UpToDate answers was assessed with 1-3 scores by reviewers. UpToDate and ChatGPT 3.5 responses were compared. RESULTS: ChatGPT did not give references in some questions in contrast to UpToDate. Information on the ChatGPT was limited to 2021. UpToDate supported the paper with subheadings, tables, figures, and algorithms. The mean accuracy score of references in ChatGPT answers was 0.25-weak/unrelated. The median (Q1-Q3) was 1.00 (1.25-2.00) for ChatGPT and 2.63 (2.75-3.00) for UpToDate, the difference was statistically significant (p < 0.001). UpToDate was observed more useful and reliable than ChatGPT. CONCLUSIONS: ChatGPT has the potential to support the physicians to find out the information but our results suggest that ChatGPT needs to be improved to increase the usefulness and reliability of medical evidence-based knowledge.

Transoral endoscopic thyroidectomy with vestibular approach (TOETVA) is a scarless thyroid surgery used as an alternative to open conventional surgery. Our aim was to investigate possible risk factors for complications and conversion during TOETVA. The study was conducted internationally by centres from Turkiye, the Republic of Korea, Italy, and Peru. A total of 406 patients who underwent TOETVA and were ≥ 18 years of age were included in the study. Demographic, pre-, intra-, and postoperative data were collected and compared between the groups with/without complication/conversion to identify possible predictors of complication/conversion. Subsequently, patients with complication/conversion were matched by the hospital, age, sex, and American Society of Anesthesiologists classification score using a propensity score (PSM) of 1:3 to eliminate confounding differences. Results were reported for the un-matched and matched groups. Complications occurred in 11 (2.7%) patients. High body mass index (26.4 ± 3.4 vs. 23.3 ± 3.7, p = 0.007), larger tumor size (1.7 ± 1.3 cm. vs. 1.1 ± 1.0 cm, p = 0.012), larger thyroid volume (20.0 ± 9.2 vs. 12.8 ± 8.5, p = 0.007) and long operation time (127.8 ± 45.0 min. vs. 97.7 ± 38.5 min., p = 0.008) were significantly associated with complications in un-matched analyses. Older age (42.7 ± 8.0 vs. 34.9 ± 9.2, p = 0.023), high BMI (26.7 ± 3.2 vs. 23.3 ± 3.7, p = 0.012), and longer operation time (160.1 ± 54.1 min. vs. 97.4 ± 37.8, p = 0.001) were significantly related to conversion in un-matched analyses. However, significance was lost after PSM for both complication and conversion. The data from this study conducted on TOETVA cases do not suggest a risk factor for complications and conversion with PSM.

Glioblastoma is the most common malignant primary central nervous system tumor and one of the most debilitating cancers. The prognosis of patients with glioblastoma remains poor, and the management of this tumor, both in its primary and recurrent forms, remains suboptimal. Despite the tremendous efforts that are being put forward by the research community to discover novel efficacious therapeutic agents and modalities, no major paradigm shifts have been established in the field in the last decade. However, this does not mirror the abundance of relevant findings and discoveries made in preclinical glioblastoma research. Hence, developing and utilizing appropriate preclinical models that faithfully recapitulate the characteristics and behavior of human glioblastoma is of utmost importance. Herein, we offer a holistic picture of the evolution of preclinical models of glioblastoma. We further elaborate on the commonly used in vitro and vivo models, delving into their development, favorable characteristics, shortcomings, and areas of potential improvement, which aids researchers in designing future experiments and utilizing the most suitable models. Additionally, this review explores progress in the fields of humanized and immunotolerant mouse models, genetically engineered animal models, 3D in vitro models, and microfluidics and highlights promising avenues for the future of preclinical glioblastoma research.

OBJECTIVE: The optimal anticoagulant treatment regimen in hospitalized coronavirus disease 2019 (COVID-19) patients is uncertain. This study aimed to compare the rates of disease progression and mortality in patients treated with low-molecular-weight heparin (LMWH) according to baseline d-dimer levels and in those who received a fixed-dose regimen irrespective of the d-dimer level. MATERIAL AND METHODS: This was a retrospective analysis of all patients admitted to a university hospital for COVID-19 pneumonia during a 1-year period. The protocol for d-dimer-driven therapy (on-protocol) was as follows: prophylactic dose when the baseline level is <1000 ng/mL, intermediate dose when the level is between 1000 and 3000 ng/mL, and therapeutic dose when the level is >3000 ng/mL. We compared the progression and mortality rates between the on-protocol and off-protocol treatment groups. The offprotocol group consisted of patients that received a fixed-dose LMWH regimen, which was not in accordance with the defined protocol. RESULTS: Of 384 patients (mean age 61.5 ± 15.9 years, 216 male), 294 patients with complete data composed the study group, and 174 patients were treated on-protocol and 120 patients were treated off-protocol. The on-protocol group had lower C-reactive protein (CRP), ferritin, lactate dehydrogenase (LDH), and d-dimer levels and higher SpO2/FiO2 levels at admission. Disease progression developed in 45/174 on-protocol patients (25.9%) vs. 53/120 off-protocol patients (44.2%) during the follow-up (P = .001), and mortality was 29 (16.7%) vs. 32 (26.7%), respectively (P = .041). Logistic regression analysis was performed and included age, presence of comorbidities, LMWH regimen, baseline SpO2/FiO2, CRP, and LDH levels as independent variables. The presence of cardiac comorbidity, age, CRP, and LDH levels, but not the LMWH treatment regimen, were associated with both disease progression and mortality. CONCLUSION: A d-dimer-driven LMWH treatment protocol is not associated with better clinical outcomes in hospitalized COVID-19 patients.
RESUMO
PURPOSE: Pafolacianine, a folate receptor alpha-targeted NIR tracer, has demonstrated clear efficacy in intraoperative molecular imaging-guided (IMI) lung cancer surgery. However, the selection of patients who would benefit from IMI remains challenging given the variability of fluorescence with patient-associated and histopathologic factors. Our goal in this study was to prospectively evaluate whether preoperative FRα/FRß staining can predict pafolacianine-based fluorescence during real-time lung cancer resections. METHODS: This was a prospective study conducted between 2018 and 2022 that reviewed core biopsy and intraoperative data from patients with suspected lung cancer. A total of 196 patients were deemed eligible, of whom core biopsies were taken from 38 patients and assessed for FRα and FRß expression by immunohistochemistry (IHC). All patients underwent infusion of pafolacianine 24 h prior to surgery. Intraoperative fluorescence images were captured with the VisionSense bandpass filter-enabled camera. All histopathologic assessments were performed by a board-certified thoracic pathologist. RESULTS: Of the 38 patients, 5 (13.1%) were found to have benign lesions (necrotizing granulomatous inflammation, lymphoid aggregates) and 1 had metastatic non-lung nodule. Thirty (81.5%) had malignant lesions, with the vast majority (23, 77.4%) being lung adenocarcinoma (7 (22.5%) SCC). None of the benign tumors (0/5, 0%) exhibited in vivo fluorescence (mean TBR of 1.72), while 95% of the malignant tumors fluoresced (mean TBR of 3.11 ± 0.31) compared to squamous cell carcinoma (1.89 ± 0.29) of the lung and sarcomatous lung metastasis (2.32 ± 0.09) (p < 0.01). The TBR was significantly higher in the malignant tumors (p = 0.009). The median FRα and FRß staining intensities were both 1.5 for benign tumors, while the FRα and FRß staining intensities were 3 and 2 for malignant tumors, respectively. Increased FRα expression was significantly associated with the presence of fluorescence (p = 0.01), CONCLUSION: This prospective study sought to determine whether preoperative FRα and FRß expression on core biopsy IHC correlates with intraoperative fluorescence during pafolacianine-guided surgery. These results, although of small sample size, including limited non-adenocarcinoma cohort, suggest that performing FRα IHC on preoperative core biopsies of adenocarcinomas as compared to squamous cell carcinomas could provide low-cost, clinically useful information for optimal patient selection which should be further explored in advanced clinical trials.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic affected all countries' health systems and people's lifestyles. In this study, we aimed to investigate its effects in a university hospital neurosurgery clinic. METHODS: The 2019 year's 6 months' data as a prepandemic period compared to the 2020 year's same period as a pandemic date. Demographic data were collected. Operations were divided into seven groups: tumor, spinal, vascular, cerebrospinal fluid disorders, hematoma, local, and minor surgery, respectively. We classified the hematoma cluster into subgroups to evaluate the etiology: epidural, acute subdural, subarachnoid hemorrhage, intracerebral hemorrhage, depressed skull fractures, and others. Patients' COVID-19 test results were collected. RESULTS: Total operations decreased from 972 to 795 (Δ18.2%) during the pandemic. All groups, except minor surgery cases, decreased compared to the prepandemic period. Also, vascular procedures for females increased during the pandemic period. While focusing on the hematoma subgroups, there was decreasing in epidural and subdural hematomas, depressed skull fractures, and total case numbers; an increase in subarachnoid hemorrhage and intracerebral hemorrhage. Overall mortality significantly increased to 9.6% from 6.8% during the pandemic (P = 0.033). Eight (1.0%) of 795 patients were COVID-19-positive; three of them died. Neurosurgery residents and academicians were unsatisfied with decreased number of operations, training, and research productivity. CONCLUSIONS: The pandemic and restrictions affected negatively the health system and people's access to healthcare. Our retrospective observational study aimed to evaluate these effects and take lessons for the next similar situations. People's access to health care should be considered when lockdown restrictions.

BACKGROUND: The aim of this study was to evaluate the safety and feasibility of a single-port system for transoral endoscopic thyroidectomy with vestibular access (TOETVA). MATERIALS AND METHODS: Two embalmed human cadavers were used to test the single-port technique. After positioning, a median vestibular incision was made. Adipose tissue was dissected through the mentum with a Kelly clamp to reach the subplatysmal level. The Keyport Single Port System (Richard Wolf) was then inserted. After port placement, flexible endoscopic dissectors and a 5-mm endoscope were advanced. After removing the dissectors, we inserted the ArtiSential laparoscopic instruments. We also used a 3-port TOETVA on another human cadaver to compare the results with those of the single-port surgery. RESULTS: In the first cadaver, skin tension was observed during trocar insertion and dissection. Trocar insertion resulted in skin perforation in the submental area. In the second cadaver, the single-port trocar was successfully inserted despite the significant skin tension. However, the trocar did not allow the necessary surgical maneuvers to proceed with subsequent surgical steps and create a working space. Postprocedural anatomic dissection revealed that the distal branches of the mental nerve were related to the trocar passage. CONCLUSIONS: Our cadaver study demonstrated that single-port TOETVA is unsafe and not feasible with the current technology of the Keyport single-port system. This approach needs to be improved to perform this technique without injury to distal branches of the mental nerve, skin perforation, and other complications.

Composite pheochromocytomas with a non-pheochromocytoma component stemming from an embryological origin other than the neural crest comprise a unique entity. We present a patient diagnosed with a composite pheochromocytoma with spindle cell sarcoma, which is, to our knowledge, the first case reported in the current literature. A 45-year-old female patient with elevated blood pressure had undergone adrenalectomy for clinically and radiologically diagnosed pheochromocytoma. Macroscopic examination of the specimen showed an encapsulated mass containing two nodules. One tumor was composed of large polygonal neoplastic cells with round vesicular nuclei and granular cytoplasm forming the characteristic Zellballen pattern consistent with pheochromocytoma, while the other was composed of spindle cells with hyperchromatic nuclei and prominent nucleoli, thus resembling a sarcoma. The patient was discharged on the fourth post-operative day without any complications. Even though for both tumors surgical resection is the main treatment modality, our case report aims to shed light on and discuss the etiology and management of a rarely presented composite pheochromocytoma and spindle cell sarcoma.
