Review Case Reports
The spinal metastatic melanoma with unknown primary lesions presenting as radiculopathy：Case report and literature review.
Metastatic malignant melanoma of the spine is rare, while the spinal metastatic melanoma with unknown primary lesions presenting as radiculopathy is even rarer. Summarizing and analyzing this disease can provide insight into disease development and allow optimization of clinical management. ⋯ Although spinal metastatic melanoma with unknown primary lesions presenting as radiculopathy is rare, effective management and treatment of these patients remains an important challenge for surgeons. Surgical resection can alleviate patients' chief complaints and improve their quality of life. However, it may not prolong the survival period and improve the prognosis. Postoperative radiotherapy and/or chemotherapy may be needed.

Traumatic brain injury (TBI) is the leading cause of morbidity and mortality worldwide. Several prognostic factors have been developed to predict functional outcomes and mortality rate in patients with TBI. Neutrophil-to-lymphocyte ratio (NLR) is an objective, available, low-cost, and reproducible indicator of inflammation. ⋯ Further, higher NLR value is in correlation with lower Glasgow Coma Scale scores. Thus its role as a complementary index to other factors, such as Glasgow Coma Scale, in predicting outcomes after TBI is under investigation. This review aims at gathering the most recent data on the prognostic value of NLR in patients with TBI.

Nasoseptal Flap Necrosis After Endoscopic Skull Base Surgery in the Setting of SARS-CoV-2/COVID-19.
A novel viral strain known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has created a worldwide pandemic known as coronavirus 2019 (COVID-19). Early reports from China have highlighted the risks associated with performing endoscopic endonasal skull base surgery in patients with SARS-CoV-2. We present a rare complication of nasoseptal flap (NSF) necrosis associated with COVID-19, further emphasizing the challenges of performing these procedures in this era. ⋯ To our knowledge, this is the first reported case of NSF necrosis in a patient with COVID-19. We postulate that the thrombotic complications of COVID-19 may have contributed to vascular pedicle thrombosis and NSF necrosis. Although the pathophysiology of SARS-CoV-2 and its effect on the nasal tissues is still being elucidated, this case highlights some challenges of performing endoscopic skull base surgery in the era of COVID-19.

Most articles describing the effect of the coronavirus disease 2019 (COVID-19) pandemic on neurosurgical services have been from developed countries. We report our experience in carrying out neurosurgical services at Dr. Sardjito General Hospital, Yogyakarta, Indonesia, during the time of the pandemic. ⋯ A pandemic, such as COVID-19, reduces both inpatient and outpatient neurosurgical activities. A comprehensive plan can improve both utilization and safety of the neurosurgical staff.

Review Historical Article
The Evolution of Minimally Invasive Lumbar Spine Surgery.
Spine surgery has evolved over centuries from first being practiced with Hippocratic boards and ladders to now being able to treat spinal pathologies with minimal tissue invasion. With the advent of new imaging and surgical technologies, spine surgeries can now be performed minimally invasively with smaller incisions, less blood loss, quicker return to daily activities, and increased visualization. Modern minimally invasive procedures include percutaneous pedicle screw fixation techniques and minimally invasive lateral approach for lumbar interbody fusion (i.e., minimally invasive transforaminal lumbar interbody fusion, extreme lateral interbody fusion, oblique lateral interbody fusion) and midline lumbar fusion with cortical bone trajectory screws. ⋯ The advent of computer image guidance has allowed spine surgeons to advance their ability to refine surgical techniques, increase the accuracy of spinal hardware placement, and reduce radiation exposure to the operating room staff. As the field of spine surgery looks to the future, many novel technologies are on the horizon, including robotic spine surgery, artificial intelligence, and machine learning to help improve preoperative planning, improve surgical execution, and optimize patient selection to ensure improved postoperative outcomes and patient satisfaction. As more spine surgeons begin incorporating these novel minimally invasive techniques into practice, the field of minimally invasive spine surgery will continue to innovate and evolve over the coming years.
