Neurochips: Considerations from a neurosurgeon's standpoint
Surg Neurol Int. 2021 Apr 19;12:173. doi: 10.25259/SNI_591_2020. eCollection 2021.ABSTRACTA neurochip comprises a small device based on the brain-machine interfaces that emulate the functioning synapses. Its implant in the human body allows the interaction of the brain with a computer. Although the data-processing speed is still slower than that of the human brain, they are being developed. There is no ethical conflict as long as it is used for neural rehabilitation or to supply impaired or missing neurological functions. However, other applications emerge as controversial. To the best of our knowledge, there have no been ...

Co-existence of multiple sclerosis and germinoma in an adult male: Case report
CONCLUSION: To the best of our knowledge, dual presentation of both MS and CNS germinoma has never been reported in the literature. The clinical presentation of bilateral optic neuritis (persisting for roughly 2 years before initial MS diagnosis), demyelinating plaques, and intrathecal oligoclonal bands before the development of an intraventricular mass indicates that both MS and CNS germinoma presented simultaneously in this patient. The treatment plan for this patient included carboplatin + etoposide, followed by adjuvant radiation and subsequent IVIG therapy.PMID:34084605 | PMC:PMC8168793 | DOI:10.25259/SNI_867_2020 (So...

Efficacy and safety of polyethylene glycol dural sealant system in cranial and spinal neurosurgical procedures: Meta-analysis
CONCLUSION: Dura seal material is an acceptable adjuvant for dural closure when the integrity of the dura is questionable. However, marketing it as a factor for the prevention of surgical site infection is not scientifically proved. We suggest that, for neurosurgeons, using the dural sealants are highly recommended for duraplasty, skull base approaches, and in keyhole approaches.PMID:34084610 | PMC:PMC8168650 | DOI:10.25259/SNI_132_2021 (Source: Surgical Neurology International)

Multiple cerebral hemorrhages in sepsis-disseminated intravascular coagulation versus septic embolism: An image report
CONCLUSION: In patients with a known ongoing infectious process with hemodynamic stability who develop altered mental status in the setting of a normal coagulation profile, D-dimer, positive blood cultures, and absent signs of multiorgan failure, a diagnosis of septic emboli should be entertained. Although CT can reveal macrobleeds, MRI is more sensitive in confirming cerebral microbleeds. Thus, patients in sepsis with unexplained altered sensorium should undergo an MRI of the brain to rule out septic emboli and microbleeds.PMID:34084613 | PMC:PMC8168679 | DOI:10.25259/SNI_810_2020 (Source: Surgical Neurology International)

Tumefactive multiple sclerosis versus high-grade glioma: A diagnostic dilemma
CONCLUSION: The diagnostic pathway, proposed on the basis of specific clinicoradiological features, should be followed in patients with suspected TDL. If MRI demonstrates other lesions typical of MS and LP demonstrates positive CSF-specific OCBs, then patients should undergo a short course of IV steroids to look for clinical improvement. Patients who continue to deteriorate, do not demonstrate other lesions on MRI or where the LP is negative for CSF-specific OCB, should be considered for biopsy if safe to do so. This pathway will give the patients the best chance at neurological preservation.PMID:34084626 | PMC:PMC8168700 ...

Clinical manifestations, classification, and surgical management of sacral tumors and the need for personalized approach to sacrectomy
CONCLUSION: Once a sacral tumor has reached the point of diagnostic detection, invasive sacrectomy is typically utilized (through an anterior, posterior, or combination approach) to locally isolate and resect the tumor and minimize risk of future tumor growth and additional bone loss. While institutions have varying criteria for surgical approaches, a combination of anterior and posterior approach has traditionally been used in total and high sacrectomies due to the control it provides surgeons toward the rectum and vasculature anterior to the sacrum. A posterior-only approach can be performed for tumors that failed to inv...

Awake spine surgery: An eye-opening movement
CONCLUSION: The use of awake spine surgery is beneficial for those who cannot undergo general anesthesia. However, it is limited to patients who can tolerate prone positioning with no central airway (i.e., normal BMI with a healthy airway), have no pre-existing mental health conditions (e.g., anxiety), and require a minimally invasive procedure with a short operating time. Future studies should focus on long-term efficacies of these procedures that provide further insight on the indications and limitations of awake spine surgery.PMID:34084649 | PMC:PMC8168649 | DOI:10.25259/SNI_153_2021 (Source: Surgical Neurology International)
