To explore the sagittal radiological parameters related to clinical recovery of patients with acute traumatic central cord syndrome (ATCCS) and determine the diagnostic value of related variables. ⋯ Lower neck tilt and TIA are risk factors for poor outcomes in patients with ATCCS after surgery. Neck tilt <39° and TIA <66° had significant diagnostic value for poor prognosis.

Intra-arterial nimodipine (IAN) injections are performed in refractory delayed cerebral ischemia (DCI) related to cerebral vasospasm (CVS) after spontaneous subarachnoid hemorrhage (sSAH), but the clinical benefits are inconclusive and angiographic treatment failure is observed. We analyzed angiographic IAN response in a detailed vessel-specific manner and examined the impact of poor angiographic response on the further clinical course. ⋯ The risk of angiographic treatment failure is significantly increased in older patients and those with poor WFNS grade as in cases of early-onset CVS. Although the extent of angiographic CVS significantly affected the development of DCI-related infarction, poor angiographic response had no impact on cerebral infarction and clinical outcome.

Surgical indications for cerebral cavernous malformations (CCMs) remain significantly center- and surgeon-dependent; available grading systems are potentially limited, as they do not include epileptologic and radiologic data. Several experienced authors proposed a new grading system for CCM and the first group of patients capable of providing its statistical validation was analyzed. ⋯ This preliminary statistical analysis demonstrated that this new grading would be applicable in surgical reality. The cutoff score of 4 correctly separated the patients who could benefit from surgical intervention from those who would not. The outcome analysis showed that the treated patients in whom the grading system has been correctly applied have a better outcome than those in whom the grading system has not been applied.

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). ⋯ 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.

Residents in multiple surgical specialties are trained to perform peripheral nerve surgery (PNS), but the extent of exposure to this field varies among specialties. This study evaluates trends in volume of PNS performed during residency for neurologic surgery trainees compared to those in plastic and orthopedic surgery between 2009 and 2019. ⋯ Neurosurgery residents exceeded the required minimum number of PNS and were increasingly more exposed to PNS. However, compared with their counterparts in orthopedic and plastic surgery, neurosurgery residents performed significantly fewer cases. Exposure for neurosurgery residents remains unchanged over the study period while plastic surgery residents experienced an increase in case volume. The deficiency in exposure for neurosurgical residents must be addressed to harness interest and proficiency in PNS.
