Unilateral biportal endoscopy (UBE) with unilateral laminotomy for bilateral decompression (ULBD) is an essential neurosurgical procedure for the treatment of lumbar spinal stenosis. This technique offers significant advantages over traditional full laminectomy and spinal fusion fixation, providing surgeons with greater operational freedom and precision in decompression. The UBE-ULBD procedure stands out because of its distinct working and observation channels, which significantly augment the surgeon's maneuverability. ⋯ Choi et al. 1 suggest that there is no statistically significant difference in postoperative visual analog scale and Oswestry Disability Index scores among the 3 techniques. However, microdiscectomy ULBD is associated with more pronounced trauma, including denervation pain of muscles. The percutaneous endoscopic ULBD offers shorter operative times and less muscle trauma and blood loss, which may have a multifaceted positive impact on postoperative recovery and symptom alleviation for patients.

This study examined the clinical significance of residual hyperintense area on T2-weighted magnetic resonance imaging (T2R) without gadolinium-enhanced lesions at the end of initial treatment (debulking surgery, concomitant radiotherapy, and temozolomide) in patients with glioblastoma. ⋯ The T2R at the end of initial treatment can predict local recurrence. However, the distant recurrence occurred frequently in T2D group. Thus, attention should be paid to local recurrences in T2R group and distant recurrences in T2D group.

Unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) is an advanced, minimally invasive spinal surgical technique characterized by the use of 2 discrete portals-one for clear visualization and continuous irrigation and the other for the dexterous manipulation of surgical instruments. This configuration not only affords an expanded view (0° or 30°) but also enhances the freedom of movement for instruments, thereby augmenting the precision and flexibility of the surgery. The superiority of UBE-TLIF lies in its capacity to facilitate rapid postoperative recovery with minimal trauma, reduced intraoperative bleeding, abbreviated hospital stays, and significant amelioration of postoperative lower back pain. ⋯ This technique reduces neural irritation during the procedure, leading to an improved patient experience postoperatively. UBE-TLIF offers a safe, efficacious, and swiftly recuperative minimally invasive option for the treatment of lumbar degenerative diseases. It diminishes reliance on costly equipment, thereby facilitating the dissemination and application of this technology in community hospitals.7.

Neurocutaneous melanosis is characterized by melanin-producing cells within the skin, leptomeninges, or brain parenchyma. It is a severe manifestation of congenital melanocytic nevus syndrome and can develop malignant melanomas. The disorder is commonly present in pediatric patients within the first two years of life and has a poor prognosis. We report a case of an 8-year-old male with epilepsy and cognitive deficit presenting spinal neurocutaneous melanosis.

There are many studies on postoperative cognitive function after surgical clipping (SC) and endovascular coiling (EC) for unruptured cerebral aneurysms, but few reports focusing on possible subclinical damage. The aim of the present study was to detect the subclinical damage after surgical intervention. ⋯ 123IMP-SPECT revealed a statistically significant reduction in ipsilateral CBF in patients who had an uneventful clinical course and no cognitive problems. The subclinical consequence could persist for at least 2 years following SC, and was less pronounced following EC.
