Summary: The study aimed to assess the relationship between trephination depth and implant stability by recording implant stability quotient (ISQ) readings at varying trephination depths in vitro. The results showed a significant relation between the trephination depth and the ISQ, with an increase in trephination depth leading to a decrease in ISQ.

Summary: The aim of this study is to propose laws of trephine operation based on a robot-assisted cutting cornea in order to obtain better microsurgical effects for keratoplasty. Robotic and manual experiments were performed using a trephine robot integrated with a microforce sensor and a handheld trephine manipulator, with porcine corneas as the test subjects. The effect of trephine operational parameters such as linear velocity, rotating angle, and angular velocity on biomechanical response were discussed. The results showed that the robot may perform the operation of trephine cornea cutting more stably compared to manual trephination.

Summary: This study compares the surgical outcomes of dacryocystorhinostomy with retrograde intubation and conjunctivo-dacryocystorhinostomy for the treatment of proximal mid-bicanalicular lacrimal obstruction. The results show that the success rates are comparable between the two procedures, but dacryocystorhinostomy with retrograde intubation has lower complication rates.

Summary: Based on the advantages of ultrasonic vibration cutting, an ultrasound-assisted corneal trepanation robotic system is developed to improve the accuracy of corneal trephination depth and corneal incision quality in corneal trephination operations. The system's design details, including the overall structure, ultrasound-assisted end effector, key mechanisms, and human-machine interaction interface, are introduced. Experimental results on grapes and porcine eyeballs show that ultrasound-assisted corneal trephination has a better operation effect compared to manual trephine.

Summary: This study evaluated the impact of cholesterol-lowering medications on the prognosis of chronic subdural hematoma (CSDH) patients. The results showed that the use of medications did not significantly affect the recurrence or reoperation rates. However, higher levels of high-density lipoprotein cholesterol (HDL-C) were associated with a lower probability of recurrence and reoperation.

Summary: Gastrointestinal (GI) bleeding is a life-threatening condition with a high incidence of hospitalizations. CT angiography is recommended as a first-line diagnostic tool for severe hematochezia patients due to its ability to locate the source of bleeding. Dual-energy CT (DECT) offers advantages such as significant radiation dose reduction and improved diagnostic accuracy through virtual noncontrast (VNC) images and postprocessing techniques. Radiologists should consider the potential pitfalls and limitations of DECT in diagnosing GI bleeding.

Summary: The aim of this study was to evaluate the size of microgaps between prefabricated and customised abutments (Astra Tech, Dentsply, York, PA, USA; Apollo Implants Components, Pabianice, Poland) mounted on a standard implant. The measurement of the microgap was performed using micro-computed tomography (MCT). The results showed that most samples did not exhibit any microgaps, and the microgap size of the Apollo abutment was higher and more variable than that of the Astra one.

Summary: In patient-based evaluation, both Tc-99m-PSMA SPECT/CT and Ga-68-PSMA PET/CT scans were positive in 95.45% (21/22) of patients. In region-based evaluation, Ga-68-PSMA PET/CT detected more regions compared to Tc-99m-PSMA SPECT/CT, with lower detection rates in the prostate bed being the main difference. There was a significant correlation between serum prostate-specific antigen level and disease extension detected by both modalities.

Summary: The imaging features of unilateral pulsatile tinnitus (PT) caused by jugular bulb wall dehiscence (JBWD) and sigmoid sinus wall dehiscence (SSWD) were investigated. The study found that the prevalence of JBWD in unilateral PT patients was 12.1%, and it was established as a causative diagnosis in 5.0% of patients. Compared with the control group, there were differences in the size and height of the jugular bulb, the extent of dehiscence, the presence of jugular bulb diverticulum, the degree of transverse sinus stenosis, and the pituitary height to sella turcica ratio.

Summary: This study investigated the outcomes of postoperative discitis treated with debridement and a novel technique focused on reducing outpatient antibiotic requirement in a low- and middle-income country (LMIC) setting. The results showed that patients with medically refractory postoperative discitis potentially have good outcomes after debridement plus 2-week local antibiotic instillation in LMICs.

Summary: Corticocortical evoked potentials (CCEPs) have emerged as a valuable intraoperative monitoring technique in eloquent brain tumor surgery, aiding in preserving critical functional areas. Current research shows the potential of CCEPs in guiding surgical decision making, reducing the risk of postoperative neurological deficits, and mapping functional connectivity, but further research and standardization are needed.

Summary: This study aimed to compare the effect of different Modic changes (MC) grades on the cage subsidence rate after spinal interbody fusion surgery. A meta-analysis was conducted on relevant randomized controlled trials and cohort studies. The results showed that MC may be associated with a higher cage subsidence rate. With the increase in MC grades, the incidence of subsidence decreased gradually, but it was always higher than that in the non-Modic changes (NMC). Oblique lumbar interbody fusion may be a better treatment choice for lumbar degenerative disease with MC.

Summary: Early exposure to neurosurgery during medical school is critical for improving recruitment into the specialty. However, about 30% of medical schools in the U.S. lack a neurosurgery program, limiting students' exposure to the field. Virtual education, facilitated by webinars during the pandemic, has advantages such as global outreach and accessibility for international medical students. This review identifies and describes 16 educational resources, serving as a guide for medical students interested in neurosurgery.
