Article Synopsis
  • This study assesses surgical residents' understanding of energy devices used in surgery, focusing on their operational principles and associated complications.
  • A 16-question test based on the "Fundamental Use of Surgical Energy" program was administered online, with 108 residents participating and an average score of only 6.5 out of 16.
  • Findings indicate that while overall knowledge is lacking, more experienced residents tend to answer more questions correctly, highlighting the need for improved training in this area.

During thyroidectomy, both needle electrodes (NE) and endotracheal tube electrodes (ETE) can be used. Incomplete contact of the endotracheal tube electrode with the vocal cords, endotracheal tube electrode may hinder an optimal outcome and even result in an inability to obtain an electromyography wave while neuromonitoring the external branch of the superior laryngeal nerve (EBSLN). There is no study that compares NE and ETE for EBSLN monitoring.

We investigated possible associations between the internal concentrations of POPs and correlations between blood and tumor tissue concentrations in patients who underwent surgery for breast cancer and breast reduction as controls. Genetic variations in CYP1A1, GSTP1, GSTM1, and GSTT1 and hOGG1 were evaluated to determine whether they represent risk factors for breast cancer. Certain POPs have been found to be associated with breast cancer development.

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.

Article Synopsis
  • * Higher microwave power leads to more notable morphological changes in the propolis extract and improves its solubility, with optimal results (highest solubility and antioxidant capacity) at 900 W.
  • * While microwave drying reduces the total phenolic content compared to fresh propolis, it maintains a comparable total flavonoid content and improves free-radical scavenging activity, especially at higher power levels.

Unlabelled: In this study, the effects of cocaine metabolite, benzoylecgonine, commonly found in wastewater on hydrogen production were investigated using microbial electrolysis cells. Benzoylecgonine dissolved in synthetic urine and human urine containing benzoylecgonine were inoculated to evaluate hydrogen production performance in microbial electrolysis cells. Microbial electrolysis cells were inoculated with synthetic urine and human urine containing the cocaine metabolite benzoylecgonine for hydrogen gas production performance.

We aimed to investigate the effects of video game habits, duration of experience, and training in different surgical clinics on the success of robotic surgery simulators. In this prospective, observational, comparative, and multi-clinical study, all participants played Temple Run and Piano Tiles 2 mobile games for 1 month, after answering a questionnaire including their sociodemographic characteristics, surgical experience, and past and current video game experience. At the end of the period, participants experienced four different robotic surgery simulator tasks (Camera Targeting 1, Energy Switching 1, Ring and Rail 2, Vertical Defect Suturing) in da Vinci Skills Simulator.

Objectives: The purpose of the study was to compare final pathology results with ultrasonography (USI) and fine needle aspiration biopsy (FNAB) results in parotis masses.

Methods: A total of 123 patients with primary parotis mass who applied to our center between 2010 and 2020 were selected for the study. Among these, 100 patients with preoperative USI, preoperative FNAB, and postoperative final pathology were included in the study.

Freehand single photon emission computed tomography (fhSPECT) is a technique that is used to monitor body's radioactivity intraoperatively. Accordingly, in this study, the feasibility of using fhSPECT for intraoperative 3D mapping in radioguided parathyroidectomy has been assessed. Patients, who were diagnosed with primary hyperparathyroidism consecutively, were scanned intraoperatively using fhSPECT to locate parathyroid adenomas before surgical procedure.

Background: Training formats for transoral endoscopic thyroidectomy vestibular approach (TOETVA) are limited. Our aim was to create and investigate a TOETVA training model for general and ENT surgeons.

Methods: A total of 15 modified Larssen solution (MLS) human cadavers were used in the study.

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.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a novel surgical technique in thyroid surgery that provides a feasible opportunity to avoid a visible neck scar. In recent years, TOETVA became popular in the thyroid surgery of selected adult patients with cosmetic concerns. We conducted a right lobectomy with the TOETVA technique in a 17-year-old adolescent with a suspicious thyroid nodule the present report aimed to describe the details of the operative technique step by step.

Introduction: Nipple-sparing mastectomy (NSM) with immediate breast reconstruction (IBR) is increasingly used for both breast cancer (TNSM) and risk reduction (RRNSM). The aim of the study is to report the results of the INSPIRE registry assessing health-related quality of life (HRQoL) comparing baseline and 1-year follow-up, regarding surgical indications and chemotherapy (CT) received.

Methods: INSPIRE is a prospective database including women undergoing NSM and IBR from 18 countries.

This study aimed to develop a validated UPLC-MS/MS method for pharmacokinetic analysis of clarithromycin in human breast milk. For sample preparation, proteins precipitated with methanol and azithromycin were used as internal standards. Clarithromycin and azithromycin detection was achieved using electrospray ionization in positive mode.

Objective: Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a scarless method that enables thyroidectomyusing natural orifice of the body. The opinion which is even common among TOETVA performing surgeons is that this surgery involves a small percentage of thyroidectomy applied patients. In this study, based on the currently accepted exclusion criteria, we aimed to determine what percentage of patients, who underwent thyroidectomy in an endemic area are actually suitable for TOETVA.

Ischiofemoral impingement ()is the compression of the muscle resulting from the narrowed distance between the lesser trochanter and the ischial bone. Congenital factors (such as developmental hip dysplasia), positional conditions (such as femoral anteversion), intertrochanteric fractures, osteotomy, and osteoarthritis may lead to the superior and medial displacement of the femur which is causing the . According to the literature, osteochondroma () is not described among the main etiological factors of There is only one case report about the relationship between and .

Objectives/hypothesis: During intraoperative neuromonitoring in thyroid surgery, two different kinds of stimulator probes, monopolar and bipolar, are commonly used to stimulate the laryngeal nerves. We explore the unique characteristics of both of these probes as they relate to intraoperative laryngeal nerve mapping.

Methods: Twenty-one patients undergoing neuromonitored thyroidectomy by a single surgeon were enrolled.

Purpose: In this study, we aimed to assess the effectiveness of malignancy stratification algorithms of the American College of Radiology (ACR) and European Thyroid Association (ETA) in the delineation of thyroid nodules using a database of nodules that were unequivocally diagnosed by means of histopathological examination and meticulously matched with the imaged nodules.

Methods: A total of 165 patients having 251 thyroid nodules with histopathologically proven definitive diagnoses during a 5-year period were included in this study. All patients had preoperatively undergone ultrasonography (US) examination, and US characteristics of the thyroid nodules were retrospectively analyzed and assigned in compliance with the thyroid imaging reporting and data system categories recommended by the ACR (ACR-TIRADS) and ETA (EU-TIRADS).
