PURPOSE
Surgical procedures in critically ill patients with spondylodiscitis are challenging and there are several controversies. Here, we present our experience with offering surgical intervention early in critically ill septic patients with spondylodiscitis.
METHOD
After we introduced a new treatment paradigm offering early but limited surgery, eight patients with spondylodiscitis complicated by severe sepsis and multiple organ failure underwent urgent surgical treatment over a 10-year period. Outcome was assessed according to the Barthel index at 12-month follow-up and at the last available follow-up (mean 89 months).
RESULTS
There were 7 men and 1 woman, with a mean age of 62 years. The preoperative ASA score was 5 in 2 patients, and 4 in 6 patients. Six of them presented with high-grade paresis, and in all of them, spondylodiscitis with intraspinal and/or paravertebral abscesses was evident in MR imaging studies. All patients underwent early surgery (within 24 h after admission). The median time in intensive care was 21 days. Out of the eight patients, seven survived. One year after surgery, five patients had a good outcome (Barthel index: 100 (1); 80 (3); and 70 (1)). At the last follow-up (mean 89 months), 4 patients had a good functional outcome (Barthel index between 60 and 80).
CONCLUSION
Early surgical treatment in critically ill patients with spondylodiscitis and sepsis may result in rapid control of infection and can provide favorable long-term outcome. A general strategy of performing only limited surgery is a valid option in such patients who have a relatively high risk for surgery.

BACKGROUND
Motor recovery following a stroke is related to the initial stroke severity and corticospinal tract integrity. One of the outcomes representing corticospinal tract integrity is the motor evoked potential (MEP). This study aimed to investigate the predictive value of MEP for motor recovery in patients with acute ischemic stroke.
PATIENTS AND METHODS
Patients with hemiparesis secondary to initial acute ischemic stroke were enrolled. MEPs of the upper limb were assessed as preserved (MEP+) or absent (MEP-) response ≤10 days post-stroke. Fugl-Meyer assessment (FMA) was performed at baseline and post-stroke at 30 and 90 days. A modified Rankin scale (mRS) was conducted at 90 days post-stroke. Patients were divided into two groups according to the highest FMA score of MEP- patients. Generalized estimating equations and logistic regression were used for our study analysis.
RESULTS
Sixty-one participants were included in this study. The highest FMA score of MEP- patients ≤10 days after stroke was 38. Among patients with an initial FMA score ≤38, FMA scores at 30 and 90 days post-stroke were significantly higher in MEP + patients than in MEP- patients. Proportional recovery at 30 and 90 days post-stroke was significantly higher in MEP + patients than in MEP- patients. MEP + patients had a higher percentage of good functional outcomes than MEP- patients, without statistical difference. Among patients with initial FMA score >38, FMA scores were 60.4 ± 4.8 and 63.9 ± 2.9 and proportional recovery was 65.2 ± 27.0% and 83.7 ± 24.6% at 30 and 90 days post-stroke, respectively.
CONCLUSIONS
Among patients with moderate-to-severe ischemic stroke, MEP + patients had better motor recoveries (approximately 70%) than MEP- patients at 90 days post-stroke. MEP + patients had better functional outcomes than MEP- patients.

Review
Thyroid surgery rates have tripled over the past three decades, making it one of the most frequently performed procedures within general surgery. Thyroid surgery is associated with the possibility of serious postoperative complications which have a significant impact on the patient's quality of life. Recurrent laryngeal nerve (RLN) palsy and external branch of the superior laryngeal nerve (EBSLN) palsy are, next to hypoparathyroidism and postoperative bleeding, some of the most common complications. The introduction of neuromonitoring into thyroid surgery, which enabled both the confirmation of anatomical integrity and the assessment of laryngeal nerve function, was a milestone that began a new era in thyroid surgery. The International Neural Monitoring Study Group has produced a standardization of the technique of RLN and EBSLN monitoring during thyroid and parathyroid surgery, which in turn increased the prevalence of neural monitoring during thyroidectomy. The current status of IONM and the benefits of its use have been presented in this publication.

KEY CLINICAL MESSAGE
Bilateral vocal fold paresis (BVFP) is a rare complication in COVID-19 and should be considered as differential diagnosis in COVID-19-patients presenting with dyspnea and stridor. High-dose intravenous corticosteroids can be useful treating COVID-19-related laryngeal edema and vocal fold paresis. This case shows the complexity of laryngeal complications in COVID-19 requiring surgeries and functional therapies.
ABSTRACT
Although COVID-19 is known to affect peripheral as well as cranial nerves, there is a paucity of reports on vocal fold paresis in COVID-19, bilateral vocal fold paresis (BVFP) in particular. We describe a case of BVFP and glottal bridge synechia following COVID-19-pneumonia discussing pathomechanisms and treatment options.

BACKGROUND
Patients with an intensive care unit-acquired weakness (ICU-AW) often present clinically with severe paresis of the limb and trunk muscles while facial muscles appear less affected. To investigate whether the facial nerves are partially spared from this condition, we performed both peripheral and cranial nerve conduction studies in critically ill patients.
METHODS
In patients requiring prolonged ICU therapy, the motor and sensory nerve conduction velocities of the peroneal, ulnar and facial nerves and the muscle action potentials of the associated muscles, as well as the orbicularis oculi reflexes were assessed shortly after admission, and on ICU days 7 and 14.
RESULTS
Eighteen patients were included in the final data analysis (average age 54.2 ± 16.8 years, 8 females). The amplitudes of the peroneal nerve compound muscle action potentials (CMAPs) were reduced in all patients at ICU days 7 and 14 (F(1.39; 23.63) = 13.85; p < 0.001). There was no similar decrease in the CMAP amplitudes of the ulnar or facial nerve. Other parameters of nerve function (latencies, sensory and motor nerve conduction velocities, sensory nerve action potentials) remained unchanged. The reproducibility of the orbicularis oculi reflex was reduced during the disease course, while its latencies did not change significantly during the disease course.
CONCLUSIONS
There is a relative preservation of CMAPs in facial and hand as opposed to foot muscles. This is compatible with the clinical observation that the facial muscles in patients with ICU-AW are less severely affected. This may be primarily a function of the nerve length, and consequently more robust trophic factors in shorter nerves. Trial registration This study was prospectively registered in the German Clinical Trial Register on April 20th 2020 (DRKS00021467).

BACKGROUND/AIM
An 80-year-old male patient had complained of proximal paresis of the left leg, pain and sensory disturbances in the left abdomen, exanthema in the left lower abdomen, coprostasis, and severe abdominal pain, as well as a progressive deterioration of his general condition for weeks. The patient had already presented to three other medical centers. Colonoscopy and computed tomography of the abdomen could not explain the pronounced symptomatology. In addition, there was acute elevator paresis of the left leg and severe pruritic rash on both sides of the trunk.
CASE REPORT
At the Israelitisches Krankenhaus Hamburg (IKH), laboratory parameters of urine, stool, and blood, ultrasound, electrocardiogram, and transthoracic echocardiography diagnosis showed no abnormalities. Esophago-gastro-duodenoscopy revealed patchy erythema and moderately severe chronic low-activity Helicobacter-positive gastritis. Colonoscopically, two polyps were ablated. A neurological examination with magnetic resonance imaging and electroneurography also showed normal findings. Evidence of autoimmune or rheumatoid disease was also absent. Finally, analysis of the cerebrospinal fluid revealed a lympho-granulocytic cell count (32/3 lymphocytes, 21/3 granulocytes) and an elevated Borrelia-specific IgG index (Ai) of 20.82. This finding was confirmed by a complementary serological diagnosis, in which Borrelia-specific IgM and IgG antibodies were detected. In sum, Bannwart's syndrome was assumed to be the cause of the neurological symptoms. The 21-day borreliosis therapy included doxycycline administration and analgesia with novaminsulfone and pregabalin as needed.
CONCLUSION
A complex symptomatology of leg paresis, lower abdominal pain and sensory disturbances, exanthema, and coprostasis in combination with a long-lasting poor general condition were found to be the consequences of atypical neuroborreliosis.

INTRODUCTION
Muscle changes after stroke cannot be explained solely on the basis of corticospinal bundle damage. Muscle-specific changes contribute to limited functional recovery but have been poorly characterized.
EVIDENCE ACQUISITION
We conducted a systematic review of muscular changes occurring at the histological, neuromuscular and functional levels during the first year after the onset of post-stroke hemiplegia. A literature search was performed on PubMed, Embase and CINHAL databases up to November 2022 using a keyword combination comprising cerebral stroke, hemiplegic, atrophy, muscle structure, paresis, skeletal muscle fiber type, motor unit, oxidative stress, strength, motor control.
EVIDENCE SYNTHESIS
Twenty-seven trial reports were included in the review, out of 12,798 articles screened. Structural modifications described on the paretic side include atrophy, transformation of type II fibers into type I fibers, decrease in fiber diameter and apparent myofilament disorganization from the first week post-stroke up to the fourth month. Reported biochemical changes comprise the abnormal presence of lipid droplets and glycogen granules in the subsarcolemmal region during the first month post-stroke. At the neurophysiological level, studies indicate an early decrease in the number and activity of motor units, correlated with the degree of motor impairment. All these modifications were present to a lesser degree on the non-paretic side. Although only sparse data concerning the subacute stage are available, these changes seem to appear during the first two weeks post-stroke and continue up to the third or fourth month.
CONCLUSIONS
Considering these early pathophysiological changes on both the paretic and non-paretic sides, it seems crucial to promptly stimulate central and also peripheral muscular activation after stroke through specific rehabilitation programs focused on the maintenance of muscle capacities associated with neurological recovery or plasticity.

Postparalysis facial synkinesis (PPFS) can develop in any facial palsy and is associated with significant functional and psychosocial consequences for affected patients. While the prevention of synkinesis especially after Bell's palsy has been well examined, much less evidence exists regarding the management of patients with already established synkinesis. Therefore, the purpose of this review is to summarize the available literature and to provide an overview of the current therapeutic options for facial palsy patients with established synkinesis. A systematic literature review was undertaken, following the Preferred Reporting Items of Systematic Reviews and Meta-analyses 2020 guidelines. MEDLINE via PubMed and Cochrane Library were searched using the following strategy: ([facial palsy] OR [facial paralysis] OR [facial paresis]) AND (synkinesis) AND ([management] OR [guidelines] OR [treatment]). The initial search yielded 201 articles of which 36 original papers and 2 meta-analyses met the criteria for inclusion. Overall, the included articles provided original outcome data on 1,408 patients. Articles were divided into the following treatment categories: chemodenervation (12 studies, 536 patients), facial therapy (5 studies, 206 patients), surgical (10 studies, 389 patients), and combination therapy (9 studies, 278 patients). Results are analyzed and discussed accordingly. Significant heterogeneity in study population and design, lack of control groups, differences in postoperative follow-up, as well as the use of a variety of subjective and objective assessment tools to quantify synkinesis prevent direct comparison between treatment modalities. To date, there is no consensus on how PPFS is best treated. The lack of comparative studies and standardized outcome reporting hinder our understanding of this complex condition. Until higher quality scientific evidence is available, it remains a challenge best approached in an interdisciplinary team. An individualized multimodal therapeutic concept consisting of facial therapy, chemodenervation, and surgery should be tailored to meet the specific needs of the patient.

INTRODUCTION
Muscle weakness in persons with Parkinson disease (PD) has been frequently recognized as a nonspecific symptom. In other neurological conditions, lower limb weakness, specifically quadriceps weakness, is the factor that causes greater gait disability. Little research has evaluated the relationship between lower limb muscle strength, using objective tools, in PD persons and gait performance. The aim of this study was to analyze the correlation between lower limb muscle strength, using an isokinetic dynamometer, and the spatiotemporal gait parameters in PD, compared with age- and sex- matched healthy controls.
SUBJECTS AND METHODS
The study was conducted with 7 persons with PD -Hoehn and Yahr (HY) between II-III- and 7 healthy controls. Isokinetic knee and ankle tests at 60 and 120°/s and the 10-meter walking test at comfortable and fast walking speed, were performed on all recruited subjects.
RESULTS
Significant differences in lower limb strength-related measures and gait parameters were observed between persons with PD and controls. Gait parameters showed excellent correlations (rho = 0.7) for both lower limb: ankle plantar flexion work/body wearing at 180°/s with number of steps (indirect) and stride (direct) at both speeds, and between the ankle plantar flexion peak torque/ body wearing at 180°/s with number of steps (indirect) and stride (direct) at maximum speed; and between knee extension work/body wearing at 60°/s) with stride (direct) at self-selected speed.
CONCLUSIONS
Persons with PD (HY II-III stages) lower limb muscle strength correlates excellently with gait pattern, showing lower isokinetic strength than healthy subjects of the same age and sex. This protocol showed safety to be performed in a larger sample.

Review
BACKGROUND
Brain Arteriovenous Malformations (AVMs) located in proximity to eloquent brain regions are associated with poor surgical outcomes, which may be due to higher rates of postoperative neurological deterioration. Current treatment protocols include stereotactic radiosurgery, transarterial embolization, and surgical resection under general anesthesia. Awake Craniotomy (AC) allows intraoperative mapping of eloquent areas to improve post-operative neurologic outcomes.
OBJECTIVES
We reviewed the current literature reporting surgical outcomes and assessed the feasibility of AC for AVM resection.
METHODS
The PRISMA guidelines were utilized as a template for the review. Three databases including PubMed, Scopus, and Cochrane Library were searched using a predefined search strategy. After removing duplicates and screening, full texts were analyzed. Outcomes including the extent of resection, intra-operative and post-operative complications, and long-term neurologic outcomes were assessed.
RESULTS
12 studies were included with a total of 122 AVM cases. Spetzler-Martin grading was used for the classification of the AVMs. The asleep-awake-asleep protocol was most commonly used for AC. Complete resection was achieved in all cases except 5. Intraoperative complications included seizures (n = 2) and bleeding (n = 4). Short-term post-operative complications included hemorrhage (n = 3), neurologic dysfunctions including paresis (n = 3), hemiplegia (n = 10), dysphasia/aphasia (n = 6), cranial nerve dysfunction (n = 3), and pulmonary embolism (n = 1). Almost all neurological deficits after surgery gradually improved on subsequent follow-ups.
CONCLUSION
AVMs may shift the anatomical location of eloquent brain areas which may be mapped during AC. All studies recommended AC for the resection of AVMs in close proximity to eloquent areas as mapping during AC identifies the eloquent cortex thus promoting careful tissue handling which may preserve neurologic function and/or predict the postoperative functional status of the patients We, therefore, conclude that AC is a viable modality for AVMs resection near eloquent language and motor areas.
