This is an electromyographic study of the activity in flexor and extensor muscles of the big toe in 22 patients with a Babinski sign and 49 controls, after mechanical or electrical stimulation of the sole. The results indicate: (1) the Babinski sign is mediated by the extensor hallucis longus (EHL), and not by the extensor hallucis brevis; (2) electrical stimuli may fail to activate the EHL in these patients, and conversely may evoke EHL reflexes in control subjects; (3) in skin reflexes, electrical and mechanical stimuli are not freely interchangeable.

As the human population increased in China, the carbon monoxide is a serious environmental toxin in public health. However, predicting the delayed neuropsychiatric sequelae (DNS) of carbon monoxide poisoning (COP) has not been well studied. We investigated the independent predictors of DNS in patients with COP. This study was conducted at four hospitals in China. Data were retrospectively collected from 258 patients with COP between November 1990 and October 2011. DNS was the primary endpoint. A positive Babinski reflex was the independent predictor for DNS: sensitivity = 53.8% (95% confidence interval [CI]: 26.1-79.6), specificity = 88.6% (95% CI: 83.7-92.1), positive predictive value (PPV) = 20.0% (95% CI: 9.1-37.5), and negative predictive value (NPV) = 97.3% (95% CI: 94.0-98.9). The area under the receiver operating characteristic curve = 0.712 (95% CI: 0.544-0.880). A positive Babinski reflex was very memorable, immediately available, and applicable in clinical practice. Even when the sensitivity and PPV of a positive Babinski reflex were unsatisfactory, it had a good specificity and NPV for excluding the risk of DNS. In patients without a positive Babinski reflex, the risk for DNS was only 2.7%. This finding may help physicians make decisions about dispositions for patients with COP.

Frontiers in Pediatrics 2022We report the case of a girl aged 2 years and 10 months who had fever for 2 days, vomiting, poor mental status for 1 day, and one episode of convulsions.
CASE PRESENTATION
We report the case of a girl aged 2 years and 10 months who had fever for 2 days, vomiting, poor mental status for 1 day, and one episode of convulsions.
SYMPTOMS AND SIGNS
The patient experienced a rapid onset of symptoms with fever, vomiting, and convulsions. Upon physical examination on admission, she presented with the following: temperature 38.6°C; pulse 185 beats/min; respiration 49 beats/min; blood pressure 89/51 mmHg; drowsiness; piebald skin all over her body; rice-grain-sized pustular rashes scattered on the front chest and both lower limbs, protruding from the surface of the skin; bilateral pupils that were equal in size and a circle with a diameter of about 3.0 mm, and slow light reflex; cyanotic lips; shortness of breath; positive for the three-concave sign; a small amount of phlegm that could be heard in both lungs; capillary refill time of 5 s; cold extremities; and a positive Babinski sign.
DIAGNOSTIC METHOD
A chest computed tomography scan showed multiple nodular and flake-like high-density shadows of varying sizes in each lobe in bilateral lungs, and a cavity with blurred edges could be seen in some nodules. A cranial magnetic resonance imaging examination demonstrated that the hyperintensity of diffusion-weighted imaging could be observed on the left cerebellar hemisphere and left parietal blade. Blood cultures, sputum, cerebrospinal fluid, and bronchoalveolar lavage fluid (BALF) by fiberoptic bronchoscopy all indicated the growth of methicillin-resistant (MRSA).
TREATMENT METHODS
After admission, the child was given meropenem combined with vancomycin, cefoperazone sulbactam combined with rifamycin, linezolid (oral) for anti-infection successively, and other adjuvant therapies.
CLINICAL OUTCOMES
The patient recovered clinically and was discharged from our hospital.

Recognizing the semiologic importance of the second, and most famous, sign described by Joseph Babinski - the extension of the hallux after stimulation of the plantar region in order to differentiate organic from pithiatic paralysis- several authors have tried to find a comparable signal in the hand. After 122 years, no one has succeeded.

OBJECTIVE
Crying is a multimodal, dynamic behavior and the first way to communicate. Early identification of hearing impairment is critical for prevention of speech and language disorders. The present study aimed to assess the acoustic features of infant's cry signals to find possible differences between two groups including hearing-impaired (HI) infants and normal hearing (NH) control.
METHODS
The data were collected from 34 (17 HI, 17 NH) infants under 2 months of age. Recording of the infant cry signals was collected during the examination of the Babinski reflex and was subsequently submitted for acoustic analysis. The total duration of the recording for each infant was approximately 30 seconds. The acoustical features included fundamental frequency (F), formants (F, F, and F), intensity, jitter, shimmer, ratios of F/F and F/F, ratio of harmonic to noise, and voice break. The recording device was an Olympus ws-321M voice recorder with 44,100 Hz sampling frequency in the stereo form. Praat analysis software (version 27, 3, 5) was used to analyze the crying signals. The data were then statistically analyzed using SPSS version 21.
RESULTS
Acoustic analysis of the crying signals showed that HI infants have lower intensity and higher F and voice break than NH infants. However, the other differences were not statistically significant.
CONCLUSION
The results of the present study demonstrated that the acoustic components including F, intensity, and voice break may be used as indices to discriminate HI infants from NH infants under 2 months of age. These findings can be increased our knowledge concerning the functional mechanisms of the vocal organ in HI and NH infants.

Spiller syndrome is a rare subtype of medial medullary infarction (MMI). Herein, we report on a patient with progressing stroke who presented with the initial features of acute peripheral vestibulopathy and MMI (Spiller syndrome), as confirmed by magnetic resonance imaging (MRI). A 42-year-old man experienced acute persistent vertigo with nausea, vomiting, and severe gait instability for 6 h before presenting to the emergency department. He exhibited spontaneous right-beating horizontal-torsional nystagmus that intensified on rightward gaze. The patient fell to the left side during the Romberg test. Cranial computed tomography (CT) performed immediately upon admission did not provide evidence for ischemia or hemorrhage of the brainstem and cerebellum; however, the symptoms underwent exacerbation 4 h after admission, manifesting as left-sided limb weakness and dysarthria, without dysphagia. Furthermore, bedside examination revealed difficulty in extending the tongue to the right, positive left Babinski's sign, and abnormal vibration and position sense in the paralyzed limb. Head impulse test recording revealed a normal gain in the vestibulo-ocular reflex, and numerous consistent covert corrective saccades were captured upon turning the head to the left side. Cranial MRI depicted an acute infarct confined to the right side of the medial medulla, which met the diagnostic criteria for Spiller syndrome. Our study underscores the importance of considering the possibility of a nucleus prepositus hypoglossi lesion even if the signs and symptoms support the diagnosis of peripheral lesions in patients with acute vestibular syndrome exhibiting vascular risk factors.

RATIONALE
Bickerstaff brainstem encephalitis (BBE) and Miller-Fisher syndrome (MFS) might be a pedigree disease. Herein, we report a rare case that fits the diagnoses of both MFS and BBE.
PATIENT CONCERNS
A 48-year-old woman was hospitalized due to blurred vision and unsteady gait lasting for 9 days, and numbness of the limbs lasting for 6 days. Physical examination showed restricted eye movement without nystagmus, bilateral flattening of forehead and nasolabial folds, and positive eyelash sign. Her tongue deviated to the left when protruded. She had negative tendon reflex, bilateral Babinski signs, hypalgesia, and numbness in all limbs. She had positive Romberg sign and failed the right heel-knee-tibia tests. Her brain diffusion-weighted magnetic resonance imaging (DWI) showed an abnormally high circular signal in the brainstem surrounding the fourth ventricle. She also had cerebral spinal fluid (CSF) albuminocytological dissociation and GQ1b-IgG antibodies in both CSF and serum.
DIAGNOSES
The case fits the diagnoses of both MFS and BBE.
INTERVENTIONS
The patient was treated with dexamethasone.
OUTCOMES
The condition of the patient significantly improved after the administration of dexamethasone. Her symptoms had continued to improve by the 6-week and 2-month follow-ups.
LESSONS
These results suggest that BBE and MFS might be a pedigree disease and timely hormone therapy is expected to improve patients'outcomes.
