Purpose: To compare the sensitivity and specificity of the Optomap Panoramic200 wide-field confocal scanning laser imaging system for detecting peripheral retinal lesions.
Methods: Optomap images were obtained in patients with known retinal pathology. Two masked retinal specialists evaluated Optomap images to identify lesions requiring referral to a retinal specialist. Their performance was compared to gold standard examination with scleral indentation performed by a retinal specialist. Sensitivity was calculated overall and again for lesions that were found on clinical examination to require treatment. These sensitivities were calculated separately for lesions posterior and anterior to the equator. Specificity was calculated from fellow eyes that were found to have no pathology on clinical examination.
Results: For retinal lesions posterior to the equator, sensitivity was 74% (95% confidence interval [95% CI] 61%-87%) overall for all lesions and 76% (95% CI 59%-93%) for lesions requiring treatment. For anterior lesions, sensitivity was 45% (95% CI 28%-62%) overall and 36% (95% CI 14%-58%) for treatable lesions. Specificity was 85% (95% CI 63%-100%).
Conclusions: The Optomap showed high specificity and moderate sensitivity for lesions posterior to the equator and low sensitivity for lesions anterior to the equator.

T-Shaped Wedge Resection of the Upper Eyelid: An Alternative to the Pentagonal Wedge.
Ophthalmic Plast Reconstr Surg
January 2025
Department of Ophthalmology, Columbia University Medical Center, New York, New York.
Purpose: To report the experience with an alternative to the upper eyelid pentagonal wedge resection technique which results in improved cosmesis due to a greater alignment of incisions with relaxed skin tension lines.
Methods: A retrospective review of all patients who underwent the T-shaped wedge resection by the authors from 2009 to 2017. A horizontal eyelid crease incision is made across the upper eyelid skin.

Department of Orthopaedic Surgery, University Medical Centre Ljubljana, Ljubljana, Slovenia.
Background: Electromagnetic navigation (EMN) is an advanced technology increasingly utilized in orthopedic surgery for its ability to provide real-time intraoperative guidance. Its application in spinal surgery is evolving rapidly, particularly for complex cases like tumor lesions. Spinal osteoblastomas, characterized by their benign nature, primarily affect the posterior elements of the spine.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

Institute of Cognitive Science Marc Jeannerod, CNRS/UMR 5229, 69500, Bron, France.
While the cerebellum's role in orchestrating motor execution and routines is well established, its functional role in supporting cognition is less clear. Previous studies claim that motricity and cognition are mapped in different areas of the cerebellar cortex, with an anterior/posterior dichotomy. However, most of the studies supporting this claim either use correlational methods (neuroimaging) or are lesion studies that did not consider central covariates (such as age, gender, treatment presence, and deep nuclei impairment) known to influence motor and cognitive recoveries in patients.

Introduction: The infratemporal fossa (ITF) is considered an uncommon location for giant cell granuloma (GCG), a rare benign disease that is frequently detected in the maxilla and mandible.
Presentation Of Case: A 47-year-old male presented with right-sided hearing loss, tinnitus, and jaw claudication. Radiological imaging confirmed the presence of a mass in the ITF accompanied by bone erosion.
