AbstractHuman development rates in the Vale do Jequitinhonha, state of Minas Gerais, Brazil, called “Misery Valley,” are among the lowest in the country, not to mention the often precarious psychosocial realities that daily contact with these families reveals. The history of neurosurgery at the Neurosurgical Reference Center at the Vale do Jequitinhonha e Mucuri dates from 2004, when the first neurosurgical procedures were performed in the recently organized Section of Neurosurgery. The historical surgical series shows the positive impact of the service. In 2007, the average was 3 neurosurgeries/month. In the last year, 2018, service growth boosted the record to 34.83 neurosurgeries/month. In addition to performing elective surgery, the neurosurgery team supports the emergency team by performing some neurosurgical procedures. The service number of patients operated since the development of the service is nearly 3,000. Neurosurgery at the Santa Casa de Caridade from Diamantina has been made comparable to the best national neurosurgery services.

The history of neurosurgery falls naturally into the premodern era, where it is essentially the history of surgery to the skull and of head injuries, and the modern era, where it is the history of surgery to the brain itself, made possible by cerebral localization theory, antisepsis, and anaesthesia, all of which developed in the nineteenth century. The first known neurosurgical procedures were skull trephines, seemingly carried out on both the living and the dead. It is unclear whether these were performed for therapeutic or ritualistic reasons. There are many trepanned skulls dating back thousands of years to the Neolithic era, and perhaps to even earlier, from sites all over the world.

Background: Neurosurgery was first practiced in Victoria, BC in the 1950’s. It has grown from 1 neurosurgeon to 6 neurosurgeons today. Methods: Research into the beginning of Neurosurgery in Victoria demonstrates that it started with one surgeon and has grown significantly over the past 60 plus years. Results: Although Neurosugery started in Victoria with humble beginnings it has now developed into a sophisticated unit with 6 neurosurgeons with various subspeciality interests including complex and minimally invasive spine, cerebrovascular and neuro-oncology. Conclusions: The Neurosurgery division in Victoria has grown over the years from a single surgeon to 6 surgeons practicing a wide scope of neurosurgical procedures.

Over Time

The history of neurosurgery is filled with descriptions of brave surgeons performing surgery against great odds in an attempt to improve outcomes in their patients. In the distant past, most neurosurgical procedures were limited to trephination, and this was sometimes performed for unclear reasons. Beginning in the Renaissance and accelerating through the middle and late 19th century, a greater understanding of cerebral localization, antisepsis, anesthesia, and hemostasis led to an era of great expansion in neurosurgical approaches and techniques. During this process, frontotemporal approaches were also developed and refined over time. Progress often depended on the technical advances of scientists coupled with the innovative ideas and courage of pioneering surgeons. A better understanding of this history provides insight into where we originated as a specialty and in what directions we may go in the future. This review considers the historical events enabling the development of neurosurgery as a specialty, and how this relates to the development of frontotemporal approaches.

The history of neurosurgery in the Turkish army is not long and complex. Neurosurgery was first practiced in the Ottoman army by Cemil Pasha, who was a general surgeon. After the fall of the Ottoman Empire, the Republic of Turkey was established and modern neurosurgical procedures were applied at the Gulhane Military Medical Academy (GMMA). Maj. Zinnur Rollas, M.D., was the founder of the Department of Neurosurgery at GMMA in 1957. A modern neurosurgical program and school was established in 1965 by Col. Hamit Ziya Gokalp, M.D., who completed his residency training in the US. Today, 26 military neurosurgeons are on active duty in 11 military hospitals in Turkey. All of these neurosurgeons work in modern clinics and operating theaters. In this paper, military neurosurgery in the Turkish army is reported in 3 parts: 1) the history of neurosurgery in the Turkish military, 2) the Department of Neurosurgery at the GMMA, and 3) the duties of a military neurosurgeon in the Turkish army.

The history of neurosurgery at University of São Paulo comes from 1918, since its origins under the Department of Neurology from Chair of Psychiatric Clinic and Nervous Diseases. Professor Enjolras Vampré was the great inspiration for such medical specialty in the State of Sao Paulo. In 1929, the first neurosurgical procedures were performed in the recently (at time) organized Section of Neurosurgery. The official inauguration of the Division of Functional Neurosurgery occurred at June 1977, with the presence of worldwide well-known neuroscientists. The division suffered a deep streamlining under the leadership of Professor Raul Marino Jr., between the decades of 1990 and 2000. At this time, it was structured with the sections of neurological surgery, functional neurosurgery and neurosurgical emergency. Since 2008, Professor Manoel Jacobsen Teixeira is the Chairman of the Division and has provided the Division with the best available technological resources, performing more than 3,000 surgeries a year and training professionals who will, certainly, be some of the future leaders of brazilian neurosurgery.

Background: Neurosurgeries are at high risk of surgical site infections (SSI), a complication associated with increased morbidity, mortality, and cost. Our aim was to measure SSI incidence and risk factors following pediatric neurosurgery at CHU Sainte-Justine, the provincial center for pediatric craniofacial surgery in Québec, Canada. Methods: Retrospective cohort study of all patients with elective neurosurgery performed at CHUSJ between October 2014 and October 2018. Medical records were reviewed to compare demographics, clinical presentations, and outcomes of patients. SSIs occurring within 30 days of a procedure without implant and up to 90 days with implant, were identified. SSI incidence was measured in patient years, and risk factors were assessed using univariate logistic regressions. Results: In total, 379 patients were included with an overall SSI incidence of 3.96 patient years. We found a higher SSI incidence in 2014–2015 compared to 2016–2018 (1.82 vs 4.83 patient years). The median age was 3.90 years, and cases seemed younger than controls (1.45 vs 4.15 years). No difference between groups was found for sex, body mass index, prematurity, and length of hospitalization. The proportion of deep SSIs was greater than superficial SSIs (53.3% vs 46.7%). Cases were more likely to present with a more severe ASA score, previous history of neurosurgery, neurological conditions, and pulmonary conditions than controls: OR, 3.90 (95% CI, 1.36–11.49); OR, 2.59 (95% CI, 0.88–7.40); OR, 2.77 (95% CI, 0.98–8.41), and OR, 3.21 (95% CI, 0.86–9.94), respectively. Among patients with history of neurosurgery, a higher proportion of cases experienced a cerebrospinal fluid leak (28.6% vs 2.2%). Most patients (85.8%) received preoperative prophylactic antibiotic. Of those, 49.3% were considered appropriate based on antibiotic and timing of administration. When antibiotic dosage was also considered, the number of patients who received an appropriate antibiotic therapy decreased radically. Conclusions: Patients with comorbidities, especially neurological and pulmonary conditions, are at higher risk of SSI after neurosurgery. We are currently working on a detailed analysis to explain the increase in SSI incidence after 2016. Finally, prophylactic antibiotic therapy needs to be improved and its impact on SSI rates needs to be monitored.Funding: NoneDisclosures: None

AbstractAn increasing number of patients with a prior history of stroke present for various types of surgeries. They have varying degree of neurological disability and associated co-morbidities, which pose challenges for their perioperative management. There is paucity in literature about their management guidelines for noncardiac, noncarotid surgeries. The available literature suggests higher risk of perioperative stroke, postoperative neurological deficits, and other morbidities. Measures to reduce perioperative risks are discussed in this review. Prior optimization by improving modifiable risk factors, choosing appropriate timing of elective surgery, and careful titration of anesthesia and close monitoring are needed.

OBJECTIVEIntraoperative neuromonitoring (IOM), particularly of somatosensory-evoked potentials (SSEPs) and motor-evoked potentials (MEPs), evolved as standard of care in a variety of neurosurgical procedures. Case series report a positive impact of IOM for elective microsurgical clipping of unruptured intracranial aneurysms (ECUIA), whereas systematic evaluation of its predictive value is lacking. Therefore, the authors analyzed the neurological outcome of patients undergoing ECUIA before and after IOM introduction to this procedure.METHODSThe dates of inclusion in the study were 2007–2014. In this period, ECUIA procedures before (n = 136, NIOM-group; 2007–2010) and after introduction of IOM (n = 138, IOM-group; 2011–2014) were included. The cutoff value for SSEP/MEP abnormality was chosen as an amplitude reduction ≥ 50%. SSEP/MEP changes were correlated with neurological outcome. IOM-undetectable deficits (bulbar, vision, ataxia) were not included in risk stratification.RESULTSThere was no significant difference in sex distribution, follow-up period, subarachnoid hemorrhage risk factors, aneurysm diameter, complexity, and location. Age was higher in the IOM-group (57 vs 54 years, p = 0.012). In the IOM group, there were 18 new postoperative deficits (13.0%, 5.8% permanent), 9 hemisyndromes, 2 comas, 4 bulbar symptoms, and 3 visual deficits. In the NIOM group there were 18 new deficits (13.2%; 7.3% permanent, including 7 hemisyndromes). The groups did not significantly differ in the number or nature of postoperative deficits, nor in their recovery rate. In the IOM group, SSEPs and MEPs were available in 99% of cases. Significant changes were noted in 18 cases, 4 of which exhibited postoperative hemisyndrome, and 1 suffered from prolonged comatose state (5 true-positive cases). Twelve patients showed no new detectable deficits (false positives), however 2 of these cases showed asymptomatic infarction. Five patients with new hemisyndrome and 1 comatose patient did not show significant SSEP/MEP alterations (false negatives). Overall sensitivity of SSEP/MEP monitoring was 45.5%, specificity 89.8%, positive predictive value 27.8%, and negative predictive value 95.0%.CONCLUSIONSThe assumed positive impact of introducing SSEP/MEP monitoring on overall neurological outcome in ECUIA did not reach significance. This study suggests that from a medicolegal point of view, IOM is not stringently required in all neurovascular procedures. However, future studies should carefully address high-risk patients with complex procedures who might benefit more clearly from IOM than others.

OBJECTIVEAlthough it is known that intersurgeon variability in offering elective surgery can have major consequences for patient morbidity and healthcare spending, data addressing variability within neurosurgery are scarce. The authors performed a prospective peer review study of randomly selected neurosurgery cases in order to assess the extent of consensus regarding the decision to offer elective surgery among attending neurosurgeons across one large academic institution.METHODSAll consecutive patients who had undergone standard inpatient surgical interventions of 1 of 4 types (craniotomy for tumor [CFT], nonacute redo CFT, first-time spine surgery with/without instrumentation, and nonacute redo spine surgery with/without instrumentation) during the period 2015–2017 were retrospectively enrolled (n = 9156 patient surgeries, n = 80 randomly selected individual cases, n = 20 index cases of each type randomly selected for review). The selected cases were scored by attending neurosurgeons using a need for surgery (NFS) score based on clinical data (patient demographics, preoperative notes, radiology reports, and operative notes; n = 616 independent case reviews). Attending neurosurgeon reviewers were blinded as to performing provider and surgical outcome. Aggregate NFS scores across various categories were measured. The authors employed a repeated-measures mixed ANOVA model with autoregressive variance structure to compute omnibus statistical tests across the various surgery types. Interrater reliability (IRR) was measured using Cohen’s kappa based on binary NFS scores.RESULTSOverall, the authors found that most of the neurosurgical procedures studied were rated as “indicated” by blinded attending neurosurgeons (mean NFS = 88.3, all p values < 0.001) with greater agreement among neurosurgeon raters than expected by chance (IRR = 81.78%, p = 0.016). Redo surgery had lower NFS scores and IRR scores than first-time surgery, both for craniotomy and spine surgery (ANOVA, all p values < 0.01). Spine surgeries with fusion had lower NFS scores than spine surgeries without fusion procedures (p < 0.01).CONCLUSIONSThere was general agreement among neurosurgeons in terms of indication for surgery; however, revision surgery of all types and spine surgery with fusion procedures had the lowest amount of decision consensus. These results should guide efforts aimed at reducing unnecessary variability in surgical practice with the goal of effective allocation of healthcare resources to advance the value paradigm in neurosurgery.

BACKGROUND HbA1c between 6% and 6.9% is associated with the lowest incidence of all‐cause and CVD mortality, with a stepwise increase in all‐cause and cardiovascular mortality in those with an HbA1c >7%. • There are 30 million individuals in the United States (9.4% of the population) currently living with Diabetes Mellitus. OBJECTIVE Improving HbA1C levels in patients with uncontrolled Diabetes with a focused and collaborative effort. METHODS Our baseline data for Diabetic patients attending the outpatient department from July 2018 to July 2019 in a University-affiliated hospital showed a total of 217 patients for one physician. • Of 217 patients, 17 had HbA1C 9 and above. We contacted these patients and discussed the need for tight control of their blood glucose levels. We intended to ensure them that we care and encourage them to participate in our efforts to improve their outcome. • We referred 13 patients that agreed to participate to the Diabetic educator who would schedule an appointment with the patients, discuss their diet, exercise, how to take medications, self-monitoring, and psychosocial factors. • If needed, she would refer them to the Nutritionist based on patients’ dietary compliance. • The patients were followed up in the next two weeks via telemedicine or a phone call by the PCP to confirm and reinforce the education provided by the diabetes educator. RESULTS Number of patients that showed an improvement in HbA1C values: 11 Cumulative decrease in HbA1C values for 13 patients: 25.3 The average reduction in HbA1C: 1.94 CONCLUSIONS Our initiative to exclusively target the blood glucose level with our multidisciplinary approach has made a positive impact, which is reflected in the outcome. • It leads to an improvement in patient compliance and facilitates diabetes management to reduce the risk for complications CLINICALTRIAL NA
