Single Stage Combined Approach Sagittal En-Block Spondylectomy for L3 Vertebral Chondrosarcoma: A Technical Note.
Primary malignant tumors of the spine are rare and most commonly occur in lumbar and thoracic vertebrae. We report a rare case of retroperitoneal chondrosarcoma of L3 that was managed with sagittal en bloc spondylectomy following chemoradiation. ⋯ Sagittal en bloc spondylectomy is a preferred surgical approach for eccentrically placed spinal tumors that offers better oncological and functional outcomes.

To develop and validate a clinical-radiomics nomogram for predicting early ischemic stroke risk in patients who sustain a transient ischemic attack (TIA). ⋯ The nomogram, based on clinical ABCD2 score, carotid plaque components and radiomics score, shows good performance in predicting the risk of recurrent ischemic events in patients with TIA.

Hemorrhagic moyamoya disease (HMMD) can result in poor outcomes. Serum biomarkers may play a significant role in predicting HMMD outcomes. This study retrospectively analyzed the correlation between serum biomarkers at the time of admission and outcomes for patients with HMMD. ⋯ An elevated GPR and SIRI at admission were associated with a poor clinical outcome at the 3-month follow-up for patients with HMMD. Therefore, these biomarkers could be considered in future management decisions for these patients.

Anterior pituitary dysfunction is one of the major causes of disability and morbidity in patients suffering from traumatic brain injury (TBI). The present study was undertaken to evaluate the incidence of anterior pituitary dysfunction in cases of moderate and severe TBI, its value in long-term prognostication, and the factors that predispose to a higher incidence of anterior pituitary dysfunction in acute and chronic phases. ⋯ Thyroid and gonadotropin axes were most commonly affected and deficiency of at least 1 axis was found in 82.4% patients in the acute phase and 59.3% in the chronic phase. Thyroid axis deficiency had a negative impact on prognosis in post-TBI patients.

Endoscopic transorbital approach emerged in recent years as an effective, minimally invasive route to access Meckel's cave area. Several case series proved its effectiveness in the surgical treatment of trigeminal schwannomas. This route provides the advantages of a minimally invasive approach associated with low morbidity rates. In this anatomo-clinical study we illustrate the usefulness of the superior eyelid transorbital approach for the surgical treatment of trigeminal schwannoma guiding the clinical applicability of the anatomical findings into real surgical practice. ⋯ The endoscopic transorbital approach may offer a valuable alternative for the surgical treatment of trigeminal schwannomas. This technique provides a minimally invasive, direct and natural "interdural" route to the lateral wall of the cavernous sinus and Meckel's cave.
