Meta-Analysis
BACKGROUND
Eagle syndrome is caused by an elongated styloid process affecting carotid arteries and cranial nerves. Pain, dysphagia, tinnitus, paresthesia (classic subtype), and neurovascular events (vascular subtype) may be triggered by head movements or arise spontaneously. However, Eagle syndrome remains underappreciated in the neurological community. We aimed to determine the most common neurological and non-neurological clinical presentations in patients with Eagle syndrome and to assess the clinical outcome post-surgical resection in comparison to non-surgical therapies.
METHODOLOGY
We conducted a systematic review of patient-level data on adults with Eagle syndrome, following PRISMA guidelines. We extracted data on demographics, presenting symptoms, neurological deficits, radiological findings, and treatments, including outcomes and complications, from studies in multiple indexing databases published between 2000 and 2023. The study protocol is registered with PROSPERO.
RESULTS
In total, 285 studies met inclusion criteria, including 497 patients with Eagle syndrome (mean age 47.3 years; 49.8% female). Classical Eagle (370 patients, 74.5%) was more frequent than vascular Eagle syndrome (117 patients, 23.5%, < 0.0001). Six patients (1.2%) presented with both variants and the subvariant for four patients (0.8%) was unknown. There was a male preponderance (70.1% male) in the vascular subtype. A history of tonsillectomy was more frequent in classic (48/153 cases) than in vascular (2/33 cases) Eagle syndrome (Odds Ratio 5.2, 95% CI [1.2-22.4]; = 0.028). By contrast, cervical movements as trigger factors were more prevalent in vascular (12/33 cases) than in classic (7/153 cases) Eagle syndrome (Odds Ratio 7.95, 95% CI [2.9-21.7]; = 0.0001). Headache and Horner syndrome were more frequent in vascular Eagle syndrome and dysphagia and neck pain more prominent in classic Eagle syndrome (all < 0.01). Surgically treated patients achieved overall better outcomes than medically treated ones: Eighty-one (65.9%) of 123 medically treated patients experienced improvement or complete resolution, while the same applied to 313 (97.8%) of 320 surgical patients (Odds Ratio 1.49, 95% CI [1.1-2.0]; = 0.016).
CONCLUSIONS
Eagle syndrome is underdiagnosed with potentially serious neurovascular complications, including ischemic stroke. Surgical treatment achieves better outcomes than conservative management. Although traditionally the domain of otorhinolaryngologist, neurologist should include this syndrome in differential diagnostic considerations because of the varied neurological presentations that are amenable to effective treatment.

A prognostic model for use before elective surgery to estimate the risk of postoperative pulmonary complications (GSU-Pulmonary Score): a development and validation study in three international cohorts.
BACKGROUND
Pulmonary complications are the most common cause of death after surgery. This study aimed to derive and externally validate a novel prognostic model that can be used before elective surgery to estimate the risk of postoperative pulmonary complications and to support resource allocation and prioritisation during pandemic recovery.
METHODS
Data from an international, prospective cohort study were used to develop a novel prognostic risk model for pulmonary complications after elective surgery in adult patients (aged ≥18 years) across all operation and disease types. The primary outcome measure was postoperative pulmonary complications at 30 days after surgery, which was a composite of pneumonia, acute respiratory distress syndrome, and unexpected mechanical ventilation. Model development with candidate predictor variables was done in the GlobalSurg-CovidSurg Week dataset (global; October, 2020). Two structured machine learning techniques were explored (XGBoost and the least absolute shrinkage and selection operator [LASSO]), and the model with the best performance (GSU-Pulmonary Score) underwent internal validation using bootstrap resampling. The discrimination and calibration of the score were externally validated in two further prospective cohorts: CovidSurg-Cancer (worldwide; February to August, 2020, during the COVID-19 pandemic) and RECON (UK and Australasia; January to October, 2019, before the COVID-19 pandemic). The model was deployed as an online web application. The GlobalSurg-CovidSurg Week and CovidSurg-Cancer studies were registered with ClinicalTrials.gov, NCT04509986 and NCT04384926.
FINDINGS
Prognostic models were developed from 13 candidate predictor variables in data from 86 231 patients (1158 hospitals in 114 countries). External validation included 30 492 patients from CovidSurg-Cancer (726 hospitals in 75 countries) and 6789 from RECON (150 hospitals in three countries). The overall rates of pulmonary complications were 2·0% in derivation data, and 3·9% (CovidSurg-Cancer) and 4·7% (RECON) in the validation datasets. Penalised regression using LASSO had similar discrimination to XGBoost (area under the receiver operating curve [AUROC] 0·786, 95% CI 0·774-0·798 vs 0·785, 0·772-0·797), was more explainable, and required fewer covariables. The final GSU-Pulmonary Score included ten predictor variables and showed good discrimination and calibration upon internal validation (AUROC 0·773, 95% CI 0·751-0·795; Brier score 0·020, calibration in the large [CITL] 0·034, slope 0·954). The model performance was acceptable on external validation in CovidSurg-Cancer (AUROC 0·746, 95% CI 0·733-0·760; Brier score 0·036, CITL 0·109, slope 1·056), but with some miscalibration in RECON data (AUROC 0·716, 95% CI 0·689-0·744; Brier score 0·045, CITL 1·040, slope 1·009).
INTERPRETATION
This novel prognostic risk score uses simple predictor variables available at the time of a decision for elective surgery that can accurately stratify patients' risk of postoperative pulmonary complications, including during SARS-CoV-2 outbreaks. It could inform surgical consent, resource allocation, and hospital-level prioritisation as elective surgery is upscaled to address global backlogs.

OBJECTIVES
The study objectives were to evaluate the safety, feasibility, and risk of neurologic complications with the supraclavicular approach in the operative management of cervicothoracic-junction benign neurogenic tumors.
METHODS
Between January 2012 and April 2023, 115 patients who underwent surgical resection for cervicothoracic-junction benign neurogenic tumors were retrospectively enrolled. Patients were divided into 3 groups based on the surgical approach: supraclavicular alone (Supraclav-Alone), n = 16; Transthoracic-Alone (video-assisted thoracoscopic surgery/Open), n = 87; and supraclavicular combined with transthoracic (Supraclav + video-assisted thoracoscopic surgery/open), n = 12. Clinicopathologic variables and postoperative morbidity including neurologic complications were summarized among the groups. Logistic regression analysis was performed to identify predictors for long-term (>6 months) brachial plexus injuries.
RESULTS
The cohort comprised 28 patients (24.3%) who underwent surgical resection using a supraclavicular approach. The Supraclav-Alone group portended the most cephalad location of tumor, the smallest pathologic tumor size, the shortest operative time, the least blood loss, and the least postoperative pain. The incidence of surgical complications, phrenic nerve neuropraxia, recurrent laryngeal nerve neuropraxia, or Horner's syndrome was similar among the groups postoperatively. However, use of the supraclavicular-alone approach (adjusted odds ratio, 0.165; 95% CI, 0.017-0.775) was a predictor for long-term brachial plexus injury complications. Among patients who experienced brachial plexus injury complications, the proportion of patients achieving complete resolution was higher among those undergoing a supraclavicular approach group (Supraclav-Alone: 80.0% vs Supraclav + video-assisted thoracoscopic surgery/Open: 60.0% vs video-assisted thoracoscopic surgery/Open: 25.8%).
CONCLUSIONS
The supraclavicular approach may be a safe and feasible strategy in the management of cervicothoracic-junction benign neurogenic tumors that does not increase surgical complications and minimizes the severity of brachial plexus injury.

BACKGROUND
Cerebral infarct associated with varicella-zoster virus (VZV) has been reported in the literature, while isolated central dizziness due to lateral medullary infarct (LMI) following VZV infection is rarely reported.
CASE REPORT
We report the case of a 65-year-old man who presented to the neurology department because of herpes zoster on the right trigeminal nerve distribution. At 12 hours after admission, he developed transient vertigo along with nausea and unsteady walking and left-sided spontaneous horizontal nystagmus, gaze-evoked nystagmus, and upbeat nystagmus. The other usual signs of LMI including Horner syndrome, dysarthria, swallowing difficulty, and hemibody sensory change were absent. Video head impulse indicated decreased head impulse gain of the vestibulo-ocular reflex for the bilateral horizontal, anterior, and posterior semicircular canals with abnormal saccade waves. Suppression head impulse paradigm showed few downward saccades reflecting anti-compensatory saccades after the end of the head impulse back to the head-fixed target and decreased vestibulo-ocular reflex gain values of bilateral semicircular canals. Brain magnetic resonance imaging (MRI) showed a small infarct in the far dorsolateral portion of the left rostral medulla. The cerebrospinal fluid was positive for VZV DNA.
CONCLUSIONS
In patients with VZV infection who develop dizziness, the possibility of cerebral infarct should be considered. Patients with facial herpes zoster and neurological symptoms always be screened for stroke using MRI and lumbar puncture should be performed and acyclovir administered empirically.

PURPOSE
Emerging evidence suggests that although Horner's syndrome manifests observable facial changes, it may not comprehensively evaluate the hemodynamic alterations associated with stellate ganglion block (SGB). This study endeavors to systematically evaluate the influence of SGB on the elasticity and flow velocity of the common carotid artery (CCA) and brachial artery utilizing ultrasound wave intensity analysis (usWIA). Particularly, it focuses on patients necessitating monitoring for its effects on specific organs or regions.
METHODS
Totally, we selected 33 patients, where only 31 patients (comprising 15 males and 16 females) were included between September 2020 to January 2022 after screening patients who require SGB treatment for painful disorders. The side on which the SGB was administered depended on the patient's painful side, 13 cases underwent left stellate ganglion block (LSGB), and 18 cases underwent right stellate ganglion block (RSGB). Wave intensity (WI) data were collected by usWIA on the CCA and brachial artery before the administration of SGB and after the manifestation of Horner's syndrome. We then compared the changes in these data pre- and post-SGB using SPSS 26.0.
RESULTS
The results showed an increase in arterial compliance (AC) of the CCA and brachial artery on the blocked side after SGB ( < 0.05). In contrast, pressure-strain elastic modulus (EP) and arterial stiffness pulse wave velocity (PWVβ) decreased (for all < 0.05). Furthermore, the minimum velocity (Vmin) of the CCA exhibited a significant increase ( < 0.01), while wave intensity pulse wave velocity (PWVwi) was significantly reduced ( < 0.01). In contrast, on the contralateral side of the CCA, EP and PWVβ increased after SGB (for all < 0.05), while AC decreased ( < 0.05).
CONCLUSION
SGB has been observed to enhance the elasticity and blood flow velocity of arteries within its innervated areas. In clinical practice, usWIA can serve as an objective measurement tool for assessing the impact of SGB on arterial elasticity and flow velocity in specific organs or regions. Furthermore, unilateral SGB has been noted to diminish the arterial elasticity of the CCA on the contralateral side.

BACKGROUND Craniopharyngioma is a rare, partly cystic embryonic malformation of the sellar and parasellar region and is usually benign. This report is of a 55-year-old woman presenting with a second diagnosis of craniopharyngioma following diagnosis and successful treatment of craniopharyngioma as a 5-year-old child. CASE REPORT Our patient was diagnosed with craniopharyngioma at age 5 when she presented with headaches accompanied by nausea and vomiting, decreased visual acuity, polyurea, and polydipsia for 6 months. She was found to have diplopia and grade II papilledema. A skull X-ray showed separation of the sutures and a calcified mass in the suprasellar region. A pneumoencephalogram showed extension of the tumor into the third ventricle. Surgery was performed via transcallosal approach followed by radiotherapy at 5000 rays. She was followed up clinically and radiologically and had been disease-free until age 55, when she presented with headache and facial numbness. On examination, she had right-eye Horner syndrome, decreased sensation in the right side of the face, diplopia, and grade 2 facial palsy. An MRI revealed interval significant recurrence of the craniopharyngioma at the sellar/suprasellar mass with extension to the right Meckel's cave and the right posterior fossa. On April 6, 2023, she underwent surgical resection through a right-sided craniotomy and Kawase approach. This was followed by CyberKnife radiation therapy. CONCLUSIONS This report has presented a rare recurrence of craniopharyngioma with a 50-year interval and has highlighted the challenges in the diagnosis and the multidisciplinary approach to patient diagnosis and management.

OBJECTIVES
Horner syndrome (HS) is a rare complication of thyroid surgery. However, the relationship between the occurrence of HS and thyroid upper pole injury is still not completely clear, and there are only few reports.
CASE PRESENTATION
A 24-year-old female underwent endoscopic thyroidectomy for thyroid papillary carcinoma. The intraoperative examination found that the upper pole of the thyroid was bleeding. During hemostasis, the ultrasonic knife consciously peeled too deep and stopped. The patient developed HS immediately after operation. We analyzed the association between deep dissection of the upper thyroid pole and an increase in the HS incidence rate through literature searches and anatomical relationships.
CONCLUSIONS
Our case report discussed the potential relationship between the degree of thyroid upper pole dissection and the occurrence of HS in routine thyroid surgery, and provided a warning for the degree of thyroid upper pole dissection in the clinic to avoid HS.

INTRODUCTION
Previously, only 40 cases with extradural hemangioblastoma at the spinal nerve (none at the T1 nerve root) have been described in the medical literature. In toto, resection of this hypervascular tumor is essential to avoid bleeding complications. Surgery for hemangioblastoma at the cervicothoracic junction is complex and nerve resection of the T1 results in specific neurodeficits of the hand muscles which are not well known.
CASE REPORT
A 34-year-old woman was diagnosed with a slowly growing tumor located at the left foramen T1/T2. Pressure from the tumor resulted in Horner's syndrome and pain and paresthesia in the upper extremity. The tumor was resected in toto through a posterior midline approach and rib resection and transection of the left T1 and T2 spinal nerves. T2 hemicorporectomy and spinal stabilization were performed to gain access to and mobilize the tumor ventrally. Ptosis decreased after surgery and no neurodeficit was observed except the expected deficit (no deficit was present preoperatively) caused by the T1 resection specifically a small decrease in strength of the abductor and flexor pollicis brevis and opponens pollicis and the lateral two lumbricals. Histological examination of the tumor demonstrated a hemangioblastoma. von Hippel-Lindau disease was ruled out by genetic testing of the patient's blood. Eight-month postoperatively, all pre-operative symptoms had decreased considerably and the radiographic examination shoved unchanged pedicle screw/rod stabilization of the cervicothoracic junction.
CONCLUSION
Hemangioblastoma is a rare hypervascular tumor very rarely located at the spinal nerve. The tumor should be resected in toto to avoid recurrence and bleeding. In the current case, the location was at the T1 root necessitating complex surgery with laminectomies and hemicorporectomy of T2 and a posterior rib resection/thoracotomy. Spinal stabilization is mandatory. Preferably embolization should be performed preoperatively. T1 transection results in a specific neurodeficit which should be explained to the patient preoperatively. The patients should undergo genetic testing for Hippel-Lindau disease.

A 59-year-old male patient came to the outpatient department with complaints of left-sided hemicranial headache with drooping of the left upper eyelid (UL) for three days associated with difficulty in swallowing and deviation of the tongue. The patient had a history of vigorous coughing for the past 15 days for which he did not take any medications. He was thoroughly evaluated in the outpatient department and diagnosed with Horner's syndrome. Acute Horner's syndrome with pain is nearly a hallmark of carotid dissection, and MRI of the brain and orbit was thus advised. On MRI, a hyperdense area was noted around the left internal carotid artery for which he was advised magnetic resonance angiography, which revealed internal carotid artery dissection (ICAD) of the left side. The patient was diagnosed with left-sided Horner's syndrome following left ICAD with involvement of the left hypoglossal nerve. He was started on antiplatelets and anticoagulants and closely followed up. Early diagnosis and prompt treatment were lifesaving for this patient.

Guillain-Barré syndrome (GBS) is an acute inflammatory polyradiculoneuropathy involving the peripheral nervous system. Autonomic dysfunctions are well-known complications of GBS and are major contributors to mortality. Autonomic dysfunctions are classically described during the acute phase of illness. In the literature, Horner syndrome as a manifestation of GBS has been reported in very few cases. Here, we describe a case of GBS with an acute presentation of flaccid paraparesis associated with unilateral Horner syndrome. Detecting the cause of acute flaccid paraparesis with unilateral Horner syndrome poses a diagnostic challenge, making it crucial for clinicians to maintain a heightened awareness for distinguishing between GBS and its variants, as well as other potential mimics.
