The Author Impact Factor as a Metric to Evaluate the Impact of Neurosurgical Researchers.

OBJECTIVE: The objective of this study was to assess the Author Impact Factor (AIF) as a useful metric and as a complement to the h-index among neurosurgical researchers. METHODS: The 5-year AIF and h-index were compared among 3 groups of researchers: 1) the 100 most prolific of all time within general neurosurgical journals ("Experienced"), 2) the 100 most prolific during the 2015-2019 period within general neurosurgical journals ("Trending Group"), and 3) the 100 postgraduation year 7 neurosurgical residents with the highest h-index ("Amateur"). RESULTS: The Amateur group had a lower median h-index than the Experienced (6 vs. 55; P < 0.001) and Trending (6 vs. 43; P < 0.001) groups. The highest h-index of the Amateur group (24) was lower than the first quartile of the Experienced (46.25) and Trending (26.00) groups. The Amateur group had a lower median 5-year AIF than the Experienced (2.15 vs. 3.17; P < 0.001) and Trending (2.15 vs. 2.85; P = 0.02) groups. Unlike the h-index, the gap between the 5-year AIF distribution of the Amateur group and other groups was not profound. Although there was a positive correlation between the metrics in the 3 groups, they did not proxy for each other. For instance, while the h-index of some experienced authors that have not published recently was high, their AIFs were zero. Also, some Amateur authors published very impactful articles and had a high 5-year AIF. However, since their number of publications is inevitably low, their h-index were low. CONCLUSIONS: The AIF provides intuitive and complementary information to the h-index regarding the research output of neurosurgical authors.

Perception of gender discrimination among spine surgeons across Latin America: a web-based survey.

BACKGROUND CONTEXT: Female physicians rarely choose spine surgery as their specialty. Although the specialty's nature and its associated lifestyle are potential barriers, gender-related issues may play an important part. PURPOSE: To evaluate the gender discrimination among spine surgeons across Latin America. STUDY DESIGN: Cross-sectional survey. PATIENT SAMPLE: The participants in this study were 223 AO Spine Latin America (AOSLA) registered members who answered the web-based survey. OUTCOME MEASURES: Personal and professional demographics; gender-related objective and subjective experiences regarding career and personal life. METHODS: A survey link containing a 24-item questionnaire was sent to the members' e-mails in September 2019. The survey was designed to evaluate the perception of gender discrimination by spine surgeons during their academic and professional lives. RESULTS: Out of 223 members who answered the survey, 196 (87.96%) were male and 27 (12.11%) female. Most were orthopedic surgeons (64.13%), ≥40 years of age (55.16%), and had <20 years of experience (69.95%). Gender discrimination was more frequent among women than among men (66.67% vs. 1.02%), as did discouragement from becoming a spine surgeon, orthopedic surgeon, or neurosurgeon (81.48% vs. 0.51%). Females reported higher rates of sexual harassment (44.44% vs. 7.65%) and more often felt disadvantaged because of gender (55.56% vs. 2.55%). Working harder than men to achieve the same prestige and lack of female mentorship were the most common obstacles reported by women (55.56%). Residency/fellowship influenced the decision to postpone/avoid having children for 66.67% of women but only 37.75% of men. Creation of a Women's Committee in AO Spine was supported by 74.07% of women and 38.78% of men. CONCLUSIONS: Gender-based discrimination affects women more frequently than men in spine surgery. These experiences likely contribute to the low prevalence of female spine surgeons. Efforts to mitigate bias and support the professional development of women in neurosurgery, orthopedics and spine communities are encouraged.

Impact of surgery on ambulatory status in patients with symptomatic neoplastic spinal cord compression in southern brazil / Impacto da cirurgia sobre a capacidade de ambulatória em pacientes com compressão neoplásica sintomática da medula espinalno sul do brasil / Impacto de la cirugía en la capacidad de ambulación en pacientes con compresión medular neoplásica sintomática en el sur de brasil

ABSTRACT Background: Spinal cord compression is a common complication of spine metastasis and multiple myeloma. About 30% of patients with cancer develop symptomatic spinal metastases during their illness. Prompt diagnosis and surgical treatment of these lesions, although palliative, are likely to reduce the morbidity and improve quality of life by improving ambulatory function. Study Design: Retrospective review of medical records. Objective: To evaluate postoperative functional recovery and the epidemiological profile of neoplastic spinal cord compression in two neurosurgical centers in southern Brazil. Methods: We retrospectively analyzed the data of all patients who underwent palliative surgery for symptomatic neoplastic spine lesion from metastatic cancer, in two neurosurgical centers, between January 2003 and July 2021. The variables age, sex, neurological status, histological type, affected segment, complications and length of hospitalization were analyzed. Results: A total of 82 patients were included. The lesions occurred in the thoracic spine in 60 cases. At admission, 95% of the patients had neurological deficits, most of which were Frankel C (37%). At histopathological analysis, breast cancer was the most common primary site. After surgery, the neurological status of 46 patients (56%) was reclassified according to the Frankel scale. Of these, 22 (47%) regained ambulatory capacity. Conclusion: Surgical treatment of metastatic spinal cord compression improved neurological status and ambulatory ability in our sample. Level of evidence II; Retrospective study.

RESUMO: Introdução: A compressão medular é uma complicação comum de metástases da coluna vertebral e de mieloma múltiplo. Cerca de 30% dos pacientes com câncer desenvolvem metástases sintomáticas na coluna no decorrer da doença. O diagnóstico imediato e o tratamento cirúrgico dessas lesões, embora paliativos, em geral reduzema morbidade e melhoram a qualidade de vidaao ampliar a capacidade de deambular. Desenho do estudo: Revisão retrospectiva de prontuários médicos. Objetivo: Avaliar a recuperação funcional pós-operatória e o perfil epidemiológico da compressão medular neoplásica em dois centros de neurocirurgia do sul do Brasil. Métodos: Analisamos retrospectivamente os dados de todos os pacientes submetidos à cirurgia paliativa de lesão neoplásica sintomática da coluna decorrente decâncer metastático, em dois centros neurocirúrgicos entre janeiro de 2003 e julho de 2021. Foram analisadas as variáveis idade, sexo, estado neurológico, tipo histológico, segmento acometido, complicações e tempo de internação. Resultados: Foram incluídos 82 pacientes no estudo. As lesões ocorreram na coluna torácica em 60 casos. À internação, 95% dos pacientes apresentavam déficits neurológicos, sendoa maioria classificada como Frankel C (37%). Na análise histopatológica, o câncer de mama foi o sítio primário mais comum. Depois da cirurgia, 46 pacientes (56%) tiveram o estado neurológico reclassificado pela escala de Frankel. Entre eles, 22 (47%) recuperaram a capacidade de deambular. Conclusões: O tratamento cirúrgico da compressão medular metastática melhorou o estado neurológico e a capacidade de deambulação em nossa amostra. Nível de evidência II; Estudo retrospectivo.

Skin erosion in deep brain stimulation procedures: Using the temporalis muscle to treat this complication - A technical note.

BACKGROUND: Skin erosion is a common complication after deep brain stimulator procedures. Despite being a relatively common event, there is no standard surgical technique or a widely accepted guideline for managing this kind of complication. METHODS: We describe a case of cutaneous erosion in the connector's site of deep brain stimulation case, surgically managed with anterior displacement of the connectors and overlapping and wrapping the connections within the temporal muscle. RESULTS: Postoperatively, the patient did well and achieved complete resolution of the skin erosion, with no signs of infection or new skin lesions. CONCLUSION: This technique demonstrated to be effective in this case in the long-term follow-up.

Bruns Syndrome Caused by Intraventricular Neurocysticercosis: Literature Review

Bruns syndrome is one of the clinical presentations of intraventricular neurocysticercosis, and it is characterized by episodes of headache, vertigo and vomiting. The intraventricular form of neurocysticercosis occurs in 7% to 20% of the cases, and it is more serious than the intraparenchymal form. The management is primarily surgical, associated with pharmacological therapy with anthelmintic drugs and corticosteroids. We report the case of a patient who presented Bruns syndrome due to neurocysticercosis.
