Governance Challenges to the Neurosurgical Care of Brain Tumors in LMICs: A Systematic Review.
Low- and middle-income countries (LMICs) often struggle to provide adequate neurosurgical care due to poor governance and institutional efforts, making access to care difficult. Therefore, our review of literature aims to identify gaps in government, national, and institutional efforts to combat barriers to neurosurgical care of brain tumors in LMICs, to inform future policy and action planning. ⋯ Effective governance plays a critical role in addressing challenges as it shapes the availability of resources and policies that affect the quality of care provided. Our study outlines key challenges and strategies reported within literature in an attempt to drive government attention and thereby policy to support the neurosurgical care of brain tumors, particularly in the developing world.

Cranial surgery in antiquity: the size of trepanations during the Neolithic period in France.
The trepanation, a surgical procedure performed on the skull, finds its roots in prehistoric times. This investigation delves into the analysis of the trepanned skulls housed at the Musée de l'Homme in Paris, focusing on those found in France, a region abundant in archaeological evidence of early neurosurgical techniques. With the opportunity to scrutinize these human remains, our study aimed to analyze the dimensions of Neolithic trepanations across 41 skulls. ⋯ Additionally, we successfully applied a straightforward protocol to determine the perforation area in ten Neolithic trepanations. These findings shed light on the medical practices of ancient civilizations, particularly in France during the Neolithic era. Moreover, this study underscores the significance of museum collections as valuable resources for scientific inquiry and the historical understanding of medicine.

Labrune syndrome is a rare white matter disease characterized by angiomatous leukoencephalopathy, diffuse intracranial calcifications and supratentorial and infratentorial parenchymal cysts. The clinical worsening is often related to cyst expansion, and surgery may be advocated for symptomatic management in about one third of cases. However, no consensus exists on the surgical timing, the most effective procedure, and the long-term results. ⋯ Leukoencephalopathy with cerebral calcifications and cysts is a rare neurodegenerative disorder for which effective medical treatment is lacking. Surgery remains the only therapeutic option to control the disease to reduce the mass effect of growing cystic lesions. Almost half of the patients who underwent surgery required further approaches, with great concern for the associated disabilities. Several procedures have been described, with no evidence regarding which procedure is the most effective. Individual-based surgical planning must be advocated, tailoring the approach to limit side effects. Mini-invasive neuroendoscopic approaches may be considered to achieve satisfactory results.

To highlight the neurosurgical implications of the hypoxia-inducible factor-2α- targeting agent belzutifan in the management of both von-Hippel Lindau (VHL)-associated and sporadic hemangioblastomas (HBLs). ⋯ There is limited experience regarding the use of belzutifan for CNS hemangioblastoma. While its application has been limited to a small group of clinical cases, it has exhibited significant efficacy in reducing the size and consequences of HBLs. Based on the promising outcomes observed in individual patient experiences and ongoing clinical trials, we infer that further exploration and integration of belzutifan into neurosurgical treatment plans for both sporadic and VHL-associated HBLs are warranted.

Lumbar spine disorders often cause lower back pain, lower limb radiating pain, restricted movement, and neurological dysfunction, which seriously affect the quality of life of middle-aged and older people. It has been found that pathological changes in the spine often cause changes in the morphology and function of the paraspinal muscles (PSMs). Fatty infiltration (FI) in PSMs is closely associated with disc degeneration and Modic changes. ⋯ Some studies suggest an association between FI and adverse surgical outcomes, although conflicting results exist. These suggest that clinicians should consider FI when assessing surgical risks and outcomes. Future studies should focus on understanding the biological mechanisms underlying FI and its predictive value in spinal surgery, providing valuable insights for clinical decision-making.
