Intracranial metastases are the most common brain tumors in adults and outnumber primary brain tumors by 10 to 1. Nearly 200,000 patients are affected every year in the United States, and these metastases have become the most common neurologic complication of cancer. Intracranial metastases are occurring with increased frequency as a result of improved therapies for systemic cancers that extend survival. Most patients with brain metastases have lung cancer as the primary malignancy, followed in frequency by breast, melanoma, renal cell, and thyroid cancers. The prognosis when brain metastases are detected differs on the basis of the underlying cancer type.

Abstract Introduction Laser interstitial thermal therapy (LITT) is a routinely used in treatment of recurrent brain metastases following SRS or open craniotomy. While considered safer than craniotomy, patients do experience neurologic decline following LITT. Identifying which patients are at risk for neurologic deterioration can help better advise patients on the most appropriate treatment options for their tumor. Objective The objective of the present study was to assess the frequency and identify risk factors for neurologic decline following LITT. Methods Data was gathered on patients who underwent LITT for ablation of metastatic brain tumors at our institution between 2014–2019. These cases were analyzed retrospectively and data was collected on patient demographics, tumor characteristics, procedural details, and post-operative complications and outcomes. Pre-operative neurologic function was compared to neurologic status at the 6–12 week post-op visit. Results 16 patients underwent LITT of a total of 18 metastatic lesions during the study time period and were included in the analysis. 7/16 patients demonstrated reduced KPS or worse neurologic function at 6–12 week follow up. 4 patients (25%) demonstrated neurologic deficits that were attributable to the laser ablation procedure, and each of these 4 patients had lesions in eloquent areas. Comparatively, none of the other 12 patients analyzed had eloquent lesions (p = 0.002). The presence of a pre-op neurologic deficit was not predictive of worsening neurologic function following LITT (p = 0.35). Average lesion size in patients who experienced neurologic deficit was 5.69cm3 compared to 3.15cm3 in those that did not (p = 0.1). Conclusion Our complications rate is similar to other published case series (15–44%). LITT, while better tolerated than standard craniotomy, can lead to neurologic decline in patients with brain metastases regardless of lesion size or pre-operative functional status. Eloquence is a significant predictor of neurologic complications following laser ablation.

Acute ischemic stroke (AIS) is the most common neurologic complication of infective endocarditis. We describe a singular case report of a 62- year-old male with AIS related to the occlusion of the left middle cerebral artery. Thrombus-aspiration allowed retrieving a 6 millimeters white thrombus. The real-time polymerase chain reaction performed on the thrombus detected Coxiella Burnetii allowed the diagnosis of infective endocarditis (IE) and the identification of the specific pathogen. Coxiella Burnetii is an endemic, small, intracellular, gram-negative coccobacillus and it is a rare cause of IE. The management of AIS caused by IE remains controversial, although in the cases of major occlusion mechanical thrombectomy is associated with better clinical outcomes. IE patients could not present symptoms and signs related to the infection, therefore we underline the importance of the microbiological analysis of the retrieved thrombi especially when atypical etiology is suspected.

Paraplegia is an unpredictable neurologic complication after coronary artery bypass grafting (CABG) surgery. It is rare but fatal, and the mechanism still is unclear. We aimed to make a summary of the possible causes of paraplegia after CABG. Pubmed database was searched from January 1, 1978 to December 31, 2019, and 14 studies were finally included. Paraplegia after CABG is a multifactorial consequence, but spinal cord ischemia is the key pathological factor to postoperative paraplegia.

Introduction: Myoclonic movement is not common side effect after general anaesthesia. Since we use various intravenous agents during general anaesthesia recently, it is troublesome to find out the exact cause of this neurologic complication. Patient concerns: A 28-year-old male patient without any past medical history underwent mandibular cyst enucleation surgery under general anaesthesia. Diagnoses: Sudden myoclonic movement confined to upper trunk and left upper extremity in recovery room after uneventful GA. Outcomes: There was no significant abnormality in electroencephalography or blood tests, which were taken after the event.

Background The coronavirus disease 2019 (COVID-19) is a systemic entity that frequently implies neurologic features at presentation and complications during the disease course. We aimed to describe the characteristics and predictors for developing in-hospital neurologic manifestations in a large cohort of hospitalized patients with COVID-19 in Mexico City. Methods We analyzed records from consecutive adult patients hospitalized from March 15 to June 30, 2020, with moderate to severe COVID-19 confirmed by reverse transcription real-time polymerase chain reaction (rtRT-PCR) for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Neurologic syndromes were actively searched by a standardized structured questionnaire and physical examination, confirmed by neuroimaging, neurophysiology of laboratory analyses, as applicable. Results We studied 1,072 cases (65% men, mean age 53.2±13 years), 71 patients had pre-existing neurologic diseases (diabetic neuropathy: 17, epilepsy: 15, history of ischemic stroke: eight, migraine: six, multiple sclerosis: one, Parkinson disease: one), and 163 (15.2%) developed a new neurologic complication. Headache (41.7%), myalgia (38.5%), dysgeusia (8%), and anosmia (7%) were the most common neurologic symptoms at hospital presentation. Delirium (13.1%), objective limb weakness (5.1%), and delayed recovery of mental status after sedation withdrawal (2.5%), were the most common new neurologic syndromes. Age, headache at presentation, preexisting neurologic disease, invasive mechanical ventilation, and neutrophil/lymphocyte ratio ≥9 were independent predictors of new in-hospital neurologic complications. Conclusions Even after excluding initial clinical features and pre-existing comorbidities, new neurologic complications in hospitalized patients with COVID-19 are frequent and can be predicted from clinical information at hospital admission.

COVID-19 affects a wide spectrum of organ systems. We report a 52-year-old man with hypertension and newly diagnosed diabetes mellitus who presented with hypoxic respiratory failure due to COVID-19 and developed severe brachial plexopathy. He was not treated with prone positioning respiratory therapy. Associated with the flaccid, painfully numb left upper extremity was a livedoid, purpuric rash on his left hand and forearm consistent with COVID-19-induced microangiopathy. Neuroimaging and electrophysiological data were consistent with near diffuse left brachial plexitis with selective sparing of axillary, suprascapular and pectoral fascicles. Given his microangiopathic rash, elevated D-dimers and paucifascicular plexopathy, we postulate a patchy microvascular thrombotic plexopathy. Providers should be aware of this significant and potentially under-recognised neurologic complication of COVID-19.

Background Congenital heart disease (CHD) is the most common neonatal and pediatric cardiac indication for extracorporeal membrane oxygenation (ECMO). Risk factors of survival and neurologic complication were different in many centers. We sought to evaluate survival and neurological outcome after ECMO in patients with CHD. Methods We retrospectively reviewed the medical records of 37 patients (<16 years old) who received ECMO. Indications for ECMO were failure to wean from cardiopulmonary bypass in 18 patients, extracorporeal cardiopulmonary resuscitation (ECPR) in 13 patients, and others in 6 patients. The median cardiopulmonary resuscitation (CPR) duration in ECPR patients was 48 min (interquartile range: 38–53 min). Neurological outcomes were evaluated using the Pediatric Cerebral Performance Category (PCPC) scale one year after hospital discharge. Results The median ECMO duration was 160 (91–286) h. Twenty-nine patients (78%) were successfully weaned off ECMO. Overall survival to hospital discharge was 59%. Risk factors of mortality were as follows: ECMO duration >1 week and urine output <1 mL/kg/h in the first 24 h after ECMO induction by multivariable analysis. Of the 22 survivors, 15 (68%) patients had a favorable outcome (PCPC ≤2). Risk factors for unfavorable outcomes (PCPC ≥3) included ECPR as indication and CPR of longer than 40 min. Conclusions Longer ECMO duration and lower urine output were associated with increased mortality. Neurologic outcomes were not satisfactory when CPR was required for a longer period before ECMO establishment.

Study Design: Retrospective case series. Objective: To report contemporary rates of complications and subsequent surgery after spinal surgery in patients with skeletal dysplasia. Methods: A case series of 25 consecutive patients who underwent spinal surgery between 2007 and 2017 were identified from a single institution’s skeletal dysplasia registry. Patient demographics, medical history, surgical indication, complications, and subsequent surgeries (revisions, extension to adjacent levels, or for pathology at a non-contiguous level) were collected. Charlson comorbidity indices were calculated as a composite measure of overall health. Results: Achondroplasia was the most common skeletal dysplasia (76%) followed by spondyloepiphyseal dysplasia (20%); 1 patient had diastrophic dysplasia (4%). Average patient age was 53.2 ± 14.7 years and most patients were in excellent cardiovascular health (88% Charlson Comorbidity Index 0-4). Mean follow up after the index procedure was 57.4 ± 39.2 months (range). Indications for surgery were mostly for neurologic symptoms. The most commonly performed surgery was a multilevel thoracolumbar decompression without fusion (57%). Complications included durotomy (36%), neurologic complication (12%), and infection requiring irrigation and debridement (8%). Nine patients (36%) underwent a subsequent surgery. Three patients (12%) underwent a procedure at a non-contiguous anatomic zone, 3 (12%) underwent a revision of the previous surgery, and another 3 (12%) required extension of their previous decompression or fusion. Conclusions: Surgical complication rates remain high after spine surgery in patients with skeletal dysplasia, likely attributable to inherent characteristics of the disease. Patients should be counseled on their risk for complication and subsequent surgery.
