Case Reports
Vertical "Half-and-Half" Syndrome with Ipsilateral Pseudoabducens Palsy due to Rostral Midbrain Lacunar Infarction.
Vertical "half-and-half" syndrome, characterized by contralateral upward and ipsilateral downward gaze palsy, is a rare variant of vertical eye movement disturbance. Similarly, pseudoabducens palsy, manifesting as abductive palsy despite no lesion to the pons, constitutes another rare type of eye movement disturbance. ⋯ We present a rare case report detailing a patient exhibiting vertical "half-and-half" syndrome with ipsilateral pseudoabducens palsy following a left lacunar infarction of the thalamo-mesencephalic junction. Additionally, we discuss the potential underlying mechanisms contributing to this rare combination of eye movement disorders.

To evaluate the effectiveness of a "telestration" system in which the mentor annotates the view of the surgical field, for endoscopic transsphenoidal surgery (ETS). ⋯ The use of the telestration system during ETS facilitated the communication of the mentor's intentions to the trainee surgeon and contributed to safer, more accurate surgery. The system was also thought to be useful in reducing operative time.

To describe the experiences and current situation of AO Spine Fellows in Latin America, as well as the concerns of junior spine surgeons in their first 3 years of practice. ⋯ Currently, junior fellows in the AO Spine program report a high level of comfort with the initiative. However, our study reveals valuable insights that can contribute to its improvement. It is worth noting that there is a clear preference for the standard posterior approach persists. Nevertheless, there is a growing interest among junior surgeons in endoscopic and minimally invasive techniques. This study serves as a gateway to essential data for future studies and the enhancement of the Fellowship education program in Latin America.

Perioperative management of antithrombotic therapy is a necessary preprocedural consideration for patients prescribed direct oral anticoagulants (DOACs), vitamin K antagonists, or antiplatelet medications. There is a lack of evidence-based guidelines to help inform decision-making in managing antiplatelet and anticoagulation medications in the perioperative period around brain tumor resection. The objective of this study was to provide an example of the heterogeneity in practice and raise awareness for the need to create standardized guidelines for managing these medications. ⋯ Respondents demonstrated significant heterogeneity in their perioperative management of antiplatelet and anticoagulation medication in brain tumor resection. This may lead to an unacceptable level of heterogeneity in practice that has the potential to cause patient harm due to errors in medication management.

To investigate the effect of age and sex on odontoid parameters and their relationships with cervical sagittal alignment in children. ⋯ Age emerged as a critical determinant of OI, which increased with age among pediatric populations. Clinicians should carefully consider the disparity in OI during the assessment and restoration of cervical sagittal balance in children.
