IMPORTANCE
The severity of a health state may be quantified using health utility measures. The utility of flaccid unilateral facial paralysis and unilateral moderate to severe postparalytic facial nerve syndrome with synkinesis may be challenging to discern from photographs alone.
OBJECTIVE
To determine the societal health utility of flaccid unilateral facial paralysis, unilateral moderate to severe postparalytic facial nerve syndrome, and post-facial reanimation using standard video.
DESIGN, SETTING, AND PARTICIPANTS
This survey study was conducted at the Massachusetts Eye and Ear and the Harvard Decision Science Laboratory from June 14, 2017, to August 3, 2017. Healthy adult naïve observers were recruited through advertising in the Cambridge, Massachusetts, area. Participants (n = 298) completed the web-based, interactive survey in person. The survey comprised clinical vignettes consisting of symptom summaries, videos, and pictures depicting 5 health states.
MAIN OUTCOMES AND MEASURES
Adult naïve observers ranked the utility of 5 randomized health states (flaccid unilateral facial paralysis, unilateral moderate to severe postparalytic facial nerve syndrome, post-facial reanimation, monocular blindness, and binocular blindness) according to the visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) measures. Standard videos of patients' facial function were used.
RESULTS
In total, 377 naïve observers were recruited and completed the survey in its entirety. Of the 377 participants, 298 (79.0%) were included for analysis. Among the 298 participants, 151 (50.7%) were female, 146 (49.0%) were male, with a mean (SD) age of 33.0 (15.1) years. No differences in health utility scores (SD) were observed between flaccid unilateral facial paralysis and unilateral moderate to severe postparalytic facial nerve syndrome (VAS: 0.598 [0.213] vs 0.629 [0.207]; SG: 0.714 [0.245] vs 0.748 [0.237]; TTO: 0.716 [0.248] vs 0.741 [0.247]). Both health states rated substantially worse than monocular blindness (VAS: 0.691 [0.212]; SG: 0.817 [0.204]; TTO: 0.826 [0.196]) and post-facial reanimation (VAS: 0.742 [0.189]; SG: 0.833 [0.206]; TTO: 0.838 [0.19]).
CONCLUSIONS AND RELEVANCE
Health utility scores for flaccid unilateral facial paralysis and unilateral moderate to severe postparalytic facial nerve syndrome appeared to be equivalent and worse than that for monocular blindness, whereas scores for post-facial reanimation were substantially higher than the scores for the 2 facial movement disorders. These findings may provide insights into the societal advantages of facial reanimation surgery.

Review
The anatomy of the cortico-bulbar tract that drives voluntary movements of mimic muscles is well described. Some cases of facial palsy with inverse automatic-voluntary dissociation (emotional facial palsy; EFP) are reported in the literature. These cases suggested a completely independent path of the fibers whose lesion results in EFP. We aimed to review the clinical reports of EFP available in the literature to characterize the anatomical aspect of the fibers whose lesion results in the isolated impairment of spontaneous smiling. Cortico-pontine fibers that control spontaneous smiling arise from the medial surface of the prefrontal cortex and descend through the anterior limb of the internal capsule, thalamus, and brain steam, independently from those that control voluntary movement. The mesial temporal lobe, particularly the amygdala, plays a crucial role in the network driving emotionally evoked facial expressions. We would highlight the relevance of an unusual and rarely explored neurological sign that could be added to clinical examination in ruling out focal brain pathology, such as stroke, tumors, or multiple sclerosis.

INTRODUCTION
the number of wild poliomyelitis cases, worldwide, dropped from 350,000 cases in 1988 to 33 in 2018. Acute flaccid paralysis (AFP) surveillance is a key strategy toward achieving global polio eradication. The 2014 Ebola virus disease (EVD) epidemic in West Africa infected over 28,000 people and had devastating effects on health systems in Guinea, Liberia, and Sierra Leone. We sought to assess the effects of the 2014 Ebola outbreak on AFP surveillance in Guinea and Liberia.
METHODS
a retrospective cross-sectional analysis was performed for Guinea and Liberia to evaluate EVD´s impact on World Health Organization (WHO) AFP surveillance performance indicators during 2012-2015.
RESULTS
both Guinea and Liberia met the WHO target non-polio AFP incidence rate nationally, and generally sub-nationally, prior to the EVD outbreak; rates decreased substantially during the outbreak in seven of eight regions in Guinea and 11 of 15 counties in Liberia. Throughout the study period, both Guinea and Liberia attained appropriate overall targets nationally for "notification" and "stool adequacy" indicators, but each country experienced periods of poor regional/county-specific indicator performance.
CONCLUSION
these findings mirrored the negative effect of the Ebola outbreak on polio elimination activities in both countries and highlights the need to reinforce this surveillance system during times of crisis.

Review
RATIONALE
Facial paralysis as the initial clinical presentation of infant leukemia (IL) is rare, and the rate of its misdiagnosis is high. Identifying the clinical characteristics of IL with facial paralysis as the initial symptom is necessary to improve the understanding of the causes of facial paralysis and IL.
PATIENT CONCERNS
A 10-month-old infant had facial paralysis and recurrent fever. He was misdiagnosed as having bacterial meningitis for >2 months.
DIAGNOSES
The infant was diagnosed as having acute monocytic leukemia (M5) with central infiltration based on examinations of the bone marrow and cerebrospinal fluid by flow cytometry.
INTERVENTIONS
Before the diagnosis of leukemia, the patient was given meropenem, ceftriaxone, vancomycin, and ampicillin successively for anti-infective treatment for 2 months, and dexamethasone for several days. But he gave up further treatment after confirmed diagnosis.
OUTCOMES
Our patient discontinued treatment and discharged. From literature review, there were 6 cases (including this case) of IL with facial paralysis as the initial symptom. 80% of patients were misdiagnosis and treated with a corticosteroid in the early stage, and the mortality was 33.3%.
LESSONS
The clinical symptoms of IL with facial paralysis are not typical, with a high rate of misdiagnosis. When the cause of facial paralysis is unknown or the advance treatment effect is poor, tumor diseases should be considered. Corticosteroids should be carefully administered to children with facial paralysis.

Transcranial electrically stimulated motor-evoked potentials (tcMEPs) are widely used to evaluate motor function in humans and animals. However, the relationship between tcMEPs and the recovery of paralysis remains unclear. We previously reported that transplantation of mesenchymal stem cells to a spinal cord injury (SCI) rat model resulted in various degrees of recovery from paraplegia. As a continuation of this work, in the present study, we aimed to establish the longitudinal electrophysiological changes in this SCI rat model after mesenchymal stem cell transplantation. SCI rats were established using the weight-drop method. The model rats were transvenously transplanted with two types of mesenchymal stem cells (MSCs), one derived from rat cranial bones and the other from the bone marrow of the femur and tibia bone, 24 h after SCI. A phosphate-buffered saline (PBS) group that received only PBS was also created for comparison. The degree of paralysis was evaluated over 28 days using the Basso-Beattie-Bresnahan (BBB) scale and inclined plane task score. Extended tcMEPs were recorded using a previously reported bone-thinning technique, and the longitudinal electrophysiological changes in tcMEPs were investigated. In addition, the relationship between the time course of recovery from paralysis and reappearance of tcMEPs was revealed. The appearance of the tcMEP waveform was earlier in MSC-transplanted rats than in PBS-administered rats (earliest date was 7 days after SCI). The MEP waveforms also appeared at approximately the same level on the BBB scale (average score, 11 points). Ultimately, this study can help enhance our understanding of the relationship between neural regeneration and tcMEP recording. Further application of tcMEP in regenerative medicine research is expected.

Randomized Controlled Trial
INTRODUCTION
arthroscopic shoulder surgery has recently gained popularity, however, postoperative pain is reported as moderate to severe. Regional anesthesia is useful for the control of postoperative pain. Interscalene and supraclavicular blocks produce diaphragmatic paralysis in different proportions. The aim of this study is to find the percentage and duration of hemidiaphragmatic paralysis, by means of ultrasonographic measurements, correlated with spirometry, comparing the supraclavicular approach with interscalene.
MATERIAL AND METHODS
clinical, controlled and randomized trial. Fifty-two patients, between 18 and 90 years of age, scheduled for arthroscopic shoulder surgery were included, divided into 2 groups (interscalene or supraclavicular block). Diaphragmatic excursion was measured and spirometry was performed prior to admission to the operating room and 24 hours after installation of the block, the study concluded 24 hours after the anesthetic event.
RESULTS
vital capacity was reduced by 0.7% in the supraclavicular block and 7.7% for the interscalene, FEV1 was reduced by 0.2% for the supraclavicular and 9.5% in the interscalene with a statistically significant difference (p = 0.001). Diaphragmatic paralysis in spontaneous ventilation appeared in both approaches at 30 minutes, without significant difference. At 6 and 8 hours, paralysis continued in the interscalene group, while in the supraclavicular approach it remained preserved compared to the baseline.
CONCLUSIONS
supraclavicular block is as effective as interscalene block in arthroscopic shoulder surgery, with less diaphragmatic block (1.5 times more diaphragmatic paralysis in interscalene).

Review
The primary target of SARS-CoV-2 is the respiratory tract; nevertheless, the virus can invade extrapulmonary organs, such as the nervous system. Peripheral facial nerve palsy has been reported in COVID-19 cases as isolated, unilateral, or bilateral in the context of Guillain-Barré syndrome (GBS). In the present study, online databases, including PubMed and Google Scholar, were searched. Studies without focusing on isolated peripheral facial nerve palsy and SARS-CoV-2 were excluded. Finally, 36 patients with facial nerve palsy were included in our study using reverse transcriptase-polymerase chain reaction (RT-PCR) or antibody SARS-CoV-2 positive test. Interestingly, 23 (63.8%) of these patients had no typical history of COVID-19, and facial nerve palsy was their first clinical manifestation. The present study concludes that there is enough evidence to suggest that SARS-CoV-2 infection may present with facial nerve palsy as the initial clinical manifestation.

We describe the development of slimmer’s paralysis or ‘foot drop’ in a patient with anorexia nervosa caused by a transient peroneal nerve injury. This was caused by extreme weight loss in combination with frequently crossing the legs in the context of anorexia nervosa with body image distortion. The most important interventions were weight recovery, physical therapy and avoiding precipitating factors. The relevance of this case lies in the fact that a physical complication of a predominantly mental illness is described. Moreover, this is a possibly lesser-known complication among psychiatrists. This case reminds clinical psychiatrists that mental illness can occur together with somatic complications. It is important to be aware of the possibility of this combination, in order to allow for early intervention and avoid additional injuries. This case also emphasizes the importance of multidisciplinary cooperation with respect to mental illness, in particular eating disorders.

OBJECTIVE
Delayed paralysis is an unpredictable problem for patients undergoing complex repair of the thoracic/thoracoabdominal aorta. These experiments were designed to determine whether ethyl pyruvate (EP), a potent anti-inflammatory and antioxidant agent, might ameliorate delayed paralysis following thoracic aortic ischemia reperfusion (TAR).
METHODS
C57BL6 mice were subjected to 5 minutes of thoracic aortic ischemia followed by reperfusion for up to 48 hours. Mice received either 300 mg/kg EP or lactated ringers (LR) at 30 minutes before ischemia and 3 hours after reperfusion. Neurologic function was assessed using an established rodent scale. Spinal cord tissue was analyzed for markers of inflammation (keratinocyte chemoattractant [KC], interleukin-6 [IL-6]), microglial activation (ionized calcium-binding adapter molecule-1 [Iba-1]), and apoptosis (Bcl-2, Bax, and terminal deoxynucleotidyl transferase dUTP nick end labeling [TUNEL] staining) at 24 and 48 hours after TAR. Nissl body stained motor neurons were counted in the anterior horns sections from L1-L5 segments.
RESULTS
Ninety-three percent of the LR mice developed dense delayed paralysis between 40 and 48 hours after TAR, whereas only 39% of EP mice developed delayed paralysis (P < .01). Bcl-2 expression was higher (P < .05) and Iba-1 expression was lower (P < .05) in the EP group only at 24 hours reperfusion. At 48 hours, the number of motor neurons was higher (P < .01) and the number and TUNEL-positive cells was lower (P < .001) in the EP-treated mice. EP decreased the expression of KC (P < .01) and IL-6 (P < .001) at 48 hours after TAR.
CONCLUSIONS
The protection provided by EP against delayed paralysis correlated with preservation of motor neurons, higher expression of antiapoptotic molecules, decreased microglial cell activation, and decreased spinal cord inflammation. EP may be a treatment for humans at risk for delayed paralysis.

Enterovirus D68 (EV-D68) is an emerging pathogen associated with mild to severe respiratory disease. Since 2014, EV-D68 is also linked to acute flaccid myelitis (AFM), causing paralysis and muscle weakness in children. However, it remains unclear whether this is due to an increased pathogenicity of contemporary EV-D68 clades or increased awareness and detection of this virus. Here, we describe an infection model of primary rat cortical neurons to study the entry, replication, and functional consequences of different EV-D68 strains, including historical and contemporary strains. We demonstrate that sialic acids are important (co)receptors for infection of both neurons and respiratory epithelial cells. Using a collection of glycoengineered isogenic HEK293 cell lines, we show that sialic acids on either N-glycans or glycosphingolipids can be used for infection. Additionally, we show that both excitatory glutamatergic and inhibitory GABA-ergic neurons are susceptible and permissive to historical and contemporary EV-D68 strains. EV-D68 infection of neurons leads to the reorganization of the Golgi-endomembranes forming replication organelles, first in the soma and later in the processes. Finally, we demonstrate that the spontaneous neuronal activity of EV-D68-infected neuronal network cultured on microelectrode arrays (MEA) is decreased, independent of the virus strain. Collectively, our findings provide novel insights into neurotropism and -pathology of different EV-D68 strains, and argue that it is unlikely that increased neurotropism is a recently acquired phenotype of a specific genetic lineage. Acute flaccid myelitis (AFM) is a serious neurological illness characterized by muscle weakness and paralysis in children. Since 2014, outbreaks of AFM have emerged worldwide, and they appear to be caused by nonpolio enteroviruses, particularly enterovirus-D68 (EV-D68), an unusual enterovirus that is known to mainly cause respiratory disease. It is unknown whether these outbreaks reflect a change of EV-D68 pathogenicity or are due to increased detection and awareness of this virus in recent years. To gain more insight herein, it is crucial to define how historical and circulating EV-D68 strains infect and replicate in neurons and how they affect their physiology. This study compares the entry and replication in neurons and the functional consequences on the neural network upon infection with an old "historical" strain and contemporary "circulating" strains of EV-D68.
