Prophylactic Cranial Irradiation for Limited-Stage Small-Cell Lung Cancer Patients: Secondary Findings From the Prospective Randomized Phase 3 CONVERT Trial

Introduction

The impact of the dose and fractionation of thoracic radiotherapy on the risk of developing brain metastasis (BM) has not been evaluated prospectively in limited stage SCLC patients receiving prophylactic cerebral irradiation (PCI).

Thinning or dehiscence of bone in structures of the middle cranial fossa floor in superior semicircular canal dehiscence

BackgroundSuperior semicircular canal dehiscence (SSCD) is a rare inner ear disorder; currently, it is unknown whether the etiopathology underlying this structural irregularity affects neighboring structures. The goal is to investigate the prevalence of bone thinning in areas of the middle cranial fossa (MCF) floor in SSCD and non-SSCD patients.MethodsThis retrospective study analyzed 100 patients from March 2011 to June 2017 at a tertiary referral center. 100 patients undergoing 118 SSCD repair surgeries (18 bilateral) were identified. 12 SSCD ears were excluded due to lack of pre-operative computed tomography (CT) scans or history of prior SSCD repair at an outside facility. Non-SSCD ears were identified from routinely-obtained CT scans for temporal bone fracture (fractured sides excluded) for a total of 101 ears; 26 non-SSCD ears were excluded due to lack of high-resolution imaging.ResultsUnivariate analyses reveal that SSCD diagnosis is associated with higher rates of geniculate ganglion (GG) dehiscence compared with non-SSCD controls (42.7 vs. 24%; χ ² (1) = 9.69, P = 0.008). Individuals with SSCD depicted significantly thinner bone overlying the geniculate ganglion (GG) (0.23 ± 1.2 mm) compared to controls (0.28 ± 1.8 mm, (t(1 6 4)) = 2.1, P = 0.04). SSCD patients presented thinner bone overlying the internal auditory canal (IAC) (0.33 ± 1.3 mm) compared to patients without SSCD (0.46 ± 1.6 mm, (t(2 5 7) = 6.4, P < 0.001).ConclusionsThe increased prevalence of dehiscence of the MCF in this cohort of SSCD patients compared to non-SSCD patients suggests that the etiology underlying SSCD affects surrounding structures.     

Sepsis after elective neurosurgery: Incidence,outcomes, and predictive factors

Sepsis is a life-threatening condition resulting from systemic infection, with mortality rates approaching 30%. Most neurological surgeries are now performed electively, which permits medical optimization preoperatively. We performed a retrospective cohort analysis of 122,466 adult elective neurosurgical patients from 2012 to 2018 in the National Surgical Quality Improvement Program database. To select for a medically optimized population, patients were included if they arrived from home on the day of surgery, were not pregnant or puerperium, and had no documented evidence of preexisting infection. We analyzed demographic, comorbidity, and operative information; performed multivariate logistic regression to explore factors predictive of postoperative sepsis; and evaluated outcomes for patients who developed sepsis. Overall, 0.87% of patients developed postoperative sepsis (n = 1,067). The rate of sepsis was higher in the cranial subpopulation (1.21%; n = 330) and lower in the spinal subpopulation (0.77%; n = 733). The overall sepsis cohort was older, had more males, was more functionally dependent, had longer operation durations, and had higher rates of medical comorbidities. Minority race and smoking were not associated with sepsis. The sepsis cohort fared worse than the control cohort across all outcome measures, including prolonged length-of-stay (≥90^th percentile), discharge anywhere but home, 30-day readmission, 30-day reoperation, and 30-day mortality. Results for the cranial and spine subpopulations follow similar trends. In summary, sepsis in the elective neurosurgical population is an uncommon but devastating cause of excess morbidity and mortality.     

Investigating the association between eye colour and the Neurological Pupil index

IntroductionBrown or dark brown eyes make it difficult to distinguish the contrast between a black pupil and the surrounding iris, which may result in clinical assessment errors. The pupillometer can be used to derive an indexed value, the Neurological Pupil index™ (NPi) for pupillary light reflex. However, there are limited data associating the NPi and iris colour. We examine the NPi and eye colour association.MethodsData were pooled from the Establishing Normative Data for Pupillometer Assessments in Neuroscience Intensive Care (END-PANIC) Registry. The analysis includes 14,168 observations collected from 865 patients with neurological conditions who were admitted to the intensive care unit. Summary statistics and statistical models were developed to examine the association using Statistical Analysis Software (SAS) summary procedure.ResultsThe mean age of the cohort was 56 years (standard deviation = 17). Eye colour included dark brown (n = 339), blue (n = 234), brown (n = 173), green (n = 82), and other (n = 37). There was significant differences (p < 0.0001) between mean NPi values by eye colour [blue = 4.08 (0.92), brown = 3.34 (1.45), dark = 3.71 (1.33), green = 4.08 (0.67), other = 3.76 (1.25)]. However, a further random-effects mixed model after controlling for confounding variables revealed no significant difference in NPi values among different eye colour groups.ConclusionsThe pupillary light reflex, when assessed using the pupillometer, is not dependent on the eye colour. Practitioners are not required to consider eye colour as a confounder when they perform pupillary assessment for examining patients with neurological conditions.
