The purpose of this study was to examine the relationship between timing of preoperative surgical antibiotic prophylaxis and postoperative surgical site infections (SSIs) among patients with 1-level to 3-level lumbar fusion. ⋯ Our results show that preoperative antibiotic administration beyond 1 hour in patients who have undergone lumbar fusion is associated with higher rates of SSI.

Orbital schwannomas are a rare disease, representing about 1% of orbital tumors, potentially involving any subsite within the orbit. They usually present with painless, nonpulsatile proptosis, while diplopia and vision impairment due to extrinsic ocular muscles or optic nerve involvement are rarely observed.1 A wait-and-see policy is advocated in case of small asymptomatic lesions. However, if progressive dimensional increase or symptoms are observed, surgical resection represents the treatment of choice.2 Different surgical approaches have been proposed, mainly depending on tumor dimension and location inside the orbit, as well as surgical expertise. ⋯ The lesion was completely removed with an endoscopic transnasal approach (Video 1), without evidence of postoperative sequelae or visual impairment. Magnetic resonance imaging performed 3 months after surgery showed good surgical results without evidence of persistence of disease. A multidisciplinary approach, involving different specialists familiar with orbital anatomy and physiology, is required for a proper management of patients affected by orbital pathologies.

Cavernous venous malformations (CVMs) represent the most common benign intraorbital lesions. Enlarging or symptomatic CVMs (progressive proptosis or visual disturbances) are treated by surgical resection. For this, a variety of different surgical approaches have been described. The aim of this study was to present a contemporary series of orbital CVMs treated via open microsurgical approaches. ⋯ Resection of orbital CVMs is indicated in patients with visual disturbances or progressive proptosis. In these, microsurgical approaches can be used with minimal morbidity for complete removal of these well-circumscribed lesions.

Inflammation plays a pivotal role in acute ischemic stroke, and various inflammatory markers are known to predict prognosis of acute ischemic stroke. This study aimed to evaluate the prognostic value of systemic inflammation response index (SIRI) and systemic immune-inflammation index (SII) after mechanical thrombectomy (MT) for acute ischemic stroke caused by large artery occlusion. ⋯ Decreased SIRI and SII were associated with favorable clinical outcome after MT. SIRI and SII represent potential prognostic factors in patients undergoing MT for large artery occlusion.
