RESUMO
BACKGROUND: In neurosurgical practice, continuous care after discharge and the ability to detect subtle indicators of clinical deterioration are mandatory to prevent the progression of a disease. The care of 'unknown' patients discharged to rehabilitation homes may not have this privilege, especially in resource-poor countries such as India. OBJECTIVE: We have attempted to study the causes and outcomes of re-admissions of 'unknown' patients with previous traumatic brain injury (TBI) to estimate the quality of nursing care in our rehabilitation centers. MATERIAL AND METHODS: The electronic hospital records of all consecutive 'unknown' TBI patients with unplanned re-admissions at our institute from January 2014 to December 2018 were retrospectively reviewed and analyzed for the factors determining the risk and outcomes of re-admission. RESULTS: Out of 245 patients sent to rehabilitation homes at discharge, 47 patients (19.18%) were re-admitted. A total of 33 patients (70%) were re-admitted between 1 month and 1 year. Out of these, 38 patients (80.9%) were re-admitted because of preventable causes. Fifteen patients (31.9%) died during the hospital stay. The rest of the 32 (68%) patients were discharged after the management of the concerned condition with an average hospital stay of 9 ± 11.1 days. The average Glasgow coma scale (GCS) at re-admission of the patients who died was 6 (range 3-11). Two patients were brought in the brain dead status, whereas 20 patients (42.6%) had a GCS of 5 or below at the time of re-admission. The risk of mortality among patients with non-preventable causes was 88.9% (8/9) compared to preventable causes 18.4% (7/38). However, preventable causes for re-admission are much more common, resulting in nearly a similar overall contribution to mortality. CONCLUSIONS: There is a high rate of mortality and morbidity in 'unknown' patients with TBI because of poor post-discharge care in developing countries. Because preventable causes are the major contributor to re-admissions, the re-admission rate is a good indicator of a lack of adequate rehabilitative services. The need for improving the post-discharge management of 'unknown' patients with TBI in resource-poor countries cannot be over-emphasized.

Rathke's Cleft Cysts (RCCs) and Craniopharyngiomas (CPs) may represent disease entities on the same etio-pathological spectrum. We report the case of a 36-year-old female presenting with vision loss and menstrual irregularities, imaging shows a predominantly cystic lesion in the sellar region with suprasellar extension. She underwent a microscopic transnasal resection of the lesion. She later presented with recurrent symptoms and increased residual lesion size on imaging, a transcranial excision of the lesion was performed. Histopathology from the initial operative specimen revealed RCC with squamous metaplasia which was BRAF negative, while the specimen from the second surgery revealed BRAF positive papillary stratified squamous architecture suggestive of Papillary CP. This case adds to the evidence that both RCCs and papillary CPs may be the spectrum of the same disease. Further, papillary CPs may be an evolution from the RCCs.

OBJECTIVE: The objective of this study was to analyze the potential and convenience of using mixed reality as a teaching tool for craniovertebral junction (CVJ) anomaly pathoanatomy. METHODS: CT and CT angiography images of 2 patients with CVJ anomalies were used to construct mixed reality models in the HoloMedicine application on the HoloLens 2 headset, resulting in four viewing stations. Twenty-two participants were randomly allocated into two groups, with each participant rotating through all stations for 90 seconds, each in a different order based on their group. At every station, objective questions evaluating the understanding of CVJ pathoanatomy were answered. At the end, subjective opinion on the user experience of mixed reality was provided using a 5-point Likert scale. The objective performance of the two viewing modes was compared, and a correlation between performance and participant experience was sought. Subjective feedback was compiled and correlated with experience. RESULTS: In both groups, there was a significant improvement in median (interquartile range [IQR]) objective performance with mixed reality compared with DICOM: 1) group A: case 1, median 6 (IQR 6-7) versus 5 (IQR 3-6), p = 0.009; case 2, median 6 (IQR 6-7) versus 5 (IQR 3-6), p = 0.02; 2) group B: case 1, median 6 (IQR 5-7) versus 4 (IQR 2-5), p = 0.04; case 2, median 6 (IQR 6-7) versus 5 (IQR 3-7), p = 0.03. There was significantly higher improvement in less experienced participants in both groups for both cases: 1) group A: case 1, r = -0.8665, p = 0.0005; case 2, r = -0.8002, p = 0.03; 2) group B: case 1, r = -0.6977, p = 0.01; case 2, r = -0.7417, p = 0.009. Subjectively, mixed reality was easy to use, with less disorientation due to the visible background, and it was believed to be a useful teaching tool. CONCLUSIONS: Mixed reality is an effective teaching tool for CVJ pathoanatomy, particularly for young neurosurgeons and trainees. The versatility of mixed reality and the intuitiveness of the user experience offer many potential applications, including training, intraoperative guidance, patient counseling, and individualized medicine; consequently, mixed reality has the potential to transform neurosurgery.

Background: Various therapies ranging from plaque brachytherapy to enucleation have been applied in uveal melanomas (UM). A gamma knife (GK) is the gold standard modality for head and neck radiation therapy with enhanced precision owing to the paucity of moving parts. The literature on GK usage in UM is rich with the methodology and nuances of GK applications undergoing constant change. Objectives: This article reports on the authors' experience in using GK for tackling UM followed by a thematic review of the evolution of GK therapy for UM. Materials and Methods: Clinical and radiological data of patients with UM treated with GK at the All India Institute of Medical Sciences, New Delhi, from March 2019 to August 2020 was analyzed. A systematic search for comparative studies and case series evaluating GK usage in UM was performed. Results: Seven UM patients underwent GK, with the median dose being 28 Gy at 50%. All patients underwent clinical follow-up and 3 patients had a radiological follow-up. Six (85.7%) eyes were preserved at follow-up, and 1 (14.28%) patient developed radiation-induced cataract. There was a reduction in tumor volume in all patients with radiological follow-up with the minimum being a 33.06% reduction in size compared to the presenting volume and the maximum being the complete disappearance of tumor at follow-up. A total of 36 articles presenting various facets of GK usage in UM have been thematically reviewed. Conclusion: GK can be a viable and effective eye-preserving option for UM with catastrophic side effects becoming rare owing to progressive reduction in radiation dose.

OBJECTIVE: To compare the SimSpine (indigenously developed, low-cost model) and EasyGO! (Karl Storz, Tuttlingen, Germany) systems for simulation of endoscopic discectomy. METHODS: Twelve neurosurgery residents, 6 in postgraduate years 1-4 or equivalent (junior) and 6 in postgraduate years 5-6 or equivalent (senior), were randomly allocated (1:1) to either EasyGO! or SimSpine endoscopic visualization systems for endoscopic lumbar discectomy simulation on the same physical simulator. After the first exercise, the participants switched over to the other system, and the exercise was repeated. Time taken to dock the system, time to reach annulus, time required for task completion, dural violation, and volume of disc material removed were used for calculating objective efficiency score. Subjective scoring (Neurosurgery Education and Training School [NETS] criteria) was performed by 4 blinded mentors based on recorded video on 2 separate occasions 2 weeks apart. Cumulative score was calculated based on efficiency and Neurosurgery Education and Training School scores. RESULTS: Performance metrics were similar across the 2 platforms, regardless of participant seniority (P > 0.05). Time to reach disc space and discectomy time improved for both EasyGO! (P = 0.07 and P = 0.03, respectively) and SimSpine (P = 0.01 and P = 0.04, respectively) between first and second exercises. Efficiency and cumulative scores were better (P = 0.04 and P = 0.03 respectively) when EasyGO! was used as the first device compared with SimSpine. CONCLUSIONS: SimSpine is a cost-effective viable alternative to EasyGO for endoscopic lumbar discectomy simulation-based training.

A 14-month child presenting with complaints of spastic paraplegia was diagnosed with C6-D1 intramedullary cyst. A cysto-subarachnoid shunt was performed; the patient was clinically stable in the immediate post-operative period. On post-operative day 2, the patient developed multiple episodes of generalized tonic-clonic seizures (GTCS) with altered sensorium, NCCT head revealed bilateral diffuse parieto-occipital hypodensities. MRI brain showed on T2WI and FLAIR, diffuse hyperintensities in bilateral parieto-occipital region suggestive of posterior reversible encephalopathy syndrome (PRES). The patient never experienced hypertensive episodes and was treated with anti-epileptics. The patient's symptoms improved and repeat MRI after 10 weeks revealed normal signal intensity in bilateral parieto-occipital areas. PRES after spinal surgeries is very rare and more so in pediatric cases, CSF hypotension may contribute to PRES in such cases.

OBJECTIVE: A novel agar-based phantom was developed and assessed for ultrasonography (USG)-guided brain biopsy training. The phantom provides visual cues combined with sonologic cues, allowing multimodal training. Impact of multimodal training is evaluated through pretraining and posttraining trials. METHODS: Twenty-five participants were divided based on experience with USG-based procedures into familiar (≥3 procedures performed in the past) (n = 14) and unfamiliar (<3 procedures performed) (n = 11). Agar phantoms with an opaque top and transparent middle layer were constructed in transparent glass bowls, each having 12 embedded targets. Participants underwent 2 supervised trials of USG-guided biopsy with aluminum foil covering the glass bowls, eliminating visual cues. Between 2 trials, participants underwent unsupervised self-training on a phantom without foil cover, providing visual cues. Performance was measured through insonation efficiency (EfI), biopsy efficiency (EfB), efficiency score (Ef), error score (Er), and performance score (PS). Scores were compared between and within the 2 groups before and after training. Impact of the self-training session on subjective comfort levels with the procedure was assessed through feedback forms. RESULTS: Familiars had better pretraining EfB, Ef, Er, and PS (P < 0.001) compared with unfamiliars. After training, both performed similarly on all metrics. After training, familiars improved only in EfI (P = 0.001), with the unfamiliars showing significance in all metrics except EfI. CONCLUSIONS: Simulation and phantom-based models can never supplant training through supervised skill application in vivo but our model supplements training by enabling technical skill acquisition, especially for beginners in USG-guided brain biopsy.

OBJECTIVE: We aim to evaluate the role of frailty and inflammatory markers in predicting the short-term outcomes after catheter-associated urinary tract infections (CAUTI) and central line-associated bloodstream infections (CLABSI). METHODS: Data regarding the patients' characteristics, isolates on CAUTI and CLABSI, antibiotic susceptibility, frailty (11-point Modified Frailty Index), and inflammatory markers were retrospectively collected. Their impact on the short-term outcomes was assessed using regression modeling response. RESULTS: One hundred and one patients with CAUTI (n = 71) and CLABSI (n = 30) between January 2018 and December 2019 were included in this study. The pooled incidence rates for CAUTI were 5.50 and for CLABSI 3.58 episodes/1000 catheter-days. We observed 74.7% drug resistance in our CAUTI isolates and 93.3% in CLABSI. In the multivariate analysis, frailty (P = 0.006), neutrophil/lymphocyte ratio (NLR) (P = 0.007) and the presence of sepsis (P = 0.029) were found to be significant predictors of in-hospital mortality in CAUTI. In patients with CLABSI, frailty (P = 0.029) and NLR (P = 0.029) were found significant and along with sepsis (P = 0.069) resulted in a regression model with good accuracy in predicting mortality. The receiver operating characteristic curve showed that 11-point Modified Frailty Index and NLR as well as the regression model significantly predicted mortality with an area under the curve of 86.1%, 81.4%, and 95.4%, respectively, in CAUTI, and 70.9%, 77.8%, and 95.2%, respectively, in CLABSI.

There is paucity of evidence regarding relative performance of antibiotic-medicated (AM), silver-medicated (SM) and non-medicated (NM) ventricular catheters in controlling infection rate. We aim to quantitatively synthesize the current evidence after addition of the three-armed British Antibiotic and Silver Impregnated Catheters for ventriculoperitoneal Shunts (BASICS) trial, understand the need for further evidence using trial sequential analysis (TSA) and incorporate the indirect evidence using network meta-analysis (NMA). Randomized controlled trials (RCTs) comparing AM, SM and NM ventriculoperitoneal shunt (VPS) or external ventricular drain (EVD) were included. Antibiotic-medicated VPS show a significantly lower infection rate as compared to non-medicated VPS (RR 0.44; 95% CI: 0.27-0.73; p = 0.001), however, TSA reveals need for further evidence. SM including both EVD as well as VPS were found to be inferior to AM while no significant difference was found in comparison to the NM catheters. In NMA for VPS, the AM were found to be significantly better than SM (RR 0.41, 95% CI: 0.22-0.75) as well as NM (RR 0.42; 95% CI: 0.25-0.71) with a SUCRA of 99.8% and a mean rank of 1. However, antibiotic medicated shunts did not show a statistically significant association with reoperation rate (RR 0.99; 95% CI:0.81-1.20; p = 0.9) with no further need for evidence as per TSA.

OBJECTIVE: The authors aimed to evaluate the impact of age and frailty on the surgical outcomes of patients with glioblastoma (GBM) and to assess caregivers' perceptions regarding postdischarge care and challenges faced in the developing country of India. METHODS: This was a retrospective study of patients with histopathologically proven GBM from 2009 to 2018. Data regarding the clinical and radiological characteristics as well as surgical outcomes were collected from the institute's electronic database. Taking Indian demographics into account, the authors used the cutoff age of 60 years to define patients as elderly. Frailty was estimated using the 11-point modified frailty index (mFI-11). Patients were divided into three groups: robust, with an mFI score of 0; moderately frail, with an mFI score of 1 or 2; and severely frail, with an mFI score ≥ 3. A questionnaire-based survey was done to assess caregivers' perceptions about postdischarge care. RESULTS: Of the 276 patients, there were 93 (33.7%) elderly patients and 183 (66.3%) young or middle-aged patients. The proportion of severely frail patients was significantly more in the elderly group (38.7%) than in the young or middle-aged group (28.4%) (p < 0.001). The authors performed univariate and multivariate analysis of associations of different short-term outcomes with age, sex, frailty, and Charlson Comorbidity Index. On the multivariate analysis, only frailty was found to be a significant predictor for in-hospital mortality, postoperative complications, and length of hospital and ICU stay (p < 0.001). On Cox regression analysis, the severely frail group was found to have a significantly lower overall survival rate compared with the moderately frail (p = 0.001) and robust groups (p < 0.001). With the increase in frailty, there was a concomitant increase in the requirement for readmissions (p = 0.003), postdischarge specialist care (p = 0.001), and help from extrafamilial sources (p < 0.001). Greater dissatisfaction with psychosocial and financial support among the caregivers of severely frail patients was seen as they found themselves ill-equipped to provide postdischarge care at home (p < 0.001). CONCLUSIONS: Frailty is a better predictor of poorer surgical outcomes than chronological age in terms of duration of hospital and ICU stay, postoperative complications, and in-hospital mortality. It also adds to the psychosocial and financial burdens of the caregivers, making postdischarge care challenging.

OBJECTIVE: Erythropoietin (EPO) has been shown to be beneficial in traumatic brain injury (TBI). We have attempted to quantitatively synthesize the findings of current randomized controlled trials (RCTs) in this meta-analysis and analyzed the need for further trials using trial sequential analysis (TSA). METHODS: A systematic search was performed in PubMed, the Cochrane Library databases, and Google Scholar for RCTs until December 2019 evaluating the role of EPO in patients with TBI. Seven RCTs were finally included in the quantitative analysis. TSA was done to evaluate the need for further studies. RESULTS: The pooled estimate demonstrated that EPO significantly reduced mortality at 6 months (odds ratio [OR], 0.65; 95% confidence interval [CI], 0.43-0.97; P = 0.04) but not in hospital mortality (OR, 0.84; 95% CI, 0.31-2.32; P = 0.74). There was no significant difference in the rate of favorable outcomes with EPO (OR, 1.58; 95% CI, 0.84-2.99; P = 0.16). The rate of deep vein thrombosis (RD, -0.02; 95% CI, -0.06 to 0.02; P =0.41) was also not found to be significantly different in the 2 groups. TSA showed that the accrued information is insufficient to make any definitive conclusions. CONCLUSIONS: EPO seems to be beneficial in terms of reducing 6-month mortality, however, its effect on in-hospital mortality, neurologic outcomes, and risk of deep vein thrombosis fails to reach statistical significance. TSA suggests a need for large trials to evaluate the role of EPO in patients with TBI in a more systematic way.
