Traumatic brain injury (TBI) can have profound acute and chronic effects, leading to permanent disabilities and diminished quality of life. Pseudobulbar palsy and its infrequent subtype, Foix-Chavany-Marie Syndrome (FCMS), represent rare complications of TBI, manifesting as deficits in craniofacial motor function and automatic-voluntary dissociation. We present a case of a 58-year-old male who developed FCMS following severe TBI from a cycling accident. Initial imaging revealed extensive brain injury with subsequent development of FCMS characterised by bilateral cranial nerve dysfunction, notably facio-pharyngo-glosso-masticatory diplegia with preserved automatic motor function. This case contributes to the limited literature on traumatic FCMS, highlighting its distinct clinical features and potential for favourable outcomes compared to nontraumatic cases. Early recognition and comprehensive management, including supportive therapy and addressing underlying conditions, are paramount for optimising patient outcomes.

Pseudobulbar affect (PBA) is a neurological condition characterized by recurrent, inappropriate, and involuntary outbursts of emotion, primarily crying and laughter, which are dissociated from the individual's emotional experience. The precise underlying cause of PBA remains unknown; however, existing evidence suggests the involvement of dopaminergic, serotonergic, and glutamatergic neurotransmission within the corticopontine-cerebellar pathways responsible for regulating the motor expression of emotions. Additionally, PBA has been observed to co-occur with other neurocognitive and psychiatric disorders. Therefore, it is crucial to consider the possibility of a PBA diagnosis in patients with underlying neurological damage and disorders.

INTRODUCTION
Pseudobulbar palsy is a common symptom in patients with amyotrophic lateral sclerosis (ALS), but it is often underdiagnosed or misdiagnosed as other diseases. The Center for Neurologic Study Lability Scale (CNS-LS) is a self-report scale consisting of seven questions designed for evaluating pseudobulbar affect (PBA). The current study aimed to validate a Chinese version of the CNS-LS.
METHODS
The Chinese version of the CNS-LS was obtained through a standardized forward-backward translation and cultural adaptation. A total of 105 patients with ALS were recruited from the ALS database of Peking University Third Hospital in Beijing, China, to complete the CNS-LS. The reliability of the Chinese version was determined by the test-retest method, and receiver operating characteristic (ROC) analysis was performed for criterion validity.
RESULTS
Of 105 patients with ALS, 37 had symptoms of PBA and were diagnosed with that condition by neurologists. Forty-two patients completed the CNS-LS twice, and there was no statistically significant difference between the scores (Z = -0.896, p = 0.37). The Spearman correlation coefficient between the test and retest scores was 0.940 (p < 0.0005), and the Cronbach alpha coefficient was high (α = 0.905, n = 105). Scores of 12 or higher on the CNS-LS identified PBA with sensitivity of 0.919 and specificity of 0.882. The area under the ROC curve was 0.924.
CONCLUSION
The Chinese version of the CNS-LS demonstrated good sensitivity and specificity in the group of patients with ALS enrolled in this study. The CNS-LS should be a useful instrument for clinical and research purposes for patients in this language group.

Swallowing disorders resulting from pseudobulbar palsy are characterized by deficiencies in the oral preparatory and oral stages of the swallowing process. In certain cases, obstruction can occur when the tongue base comes into contact with the palate, impeding the intraoral bolus flow into the pharyngeal cavity. In this report, we discuss a case of severe pseudobulbar palsy, in which an intraoral bolus flowed into the pharyngeal cavity with pinching the nose. A 78-year-old man with a history of recurrent cerebral infarction was evaluated. The patient had severe dysphagia and cognitive impairment due to pseudobulbar palsy. A videofluoroscopic examination of swallowing (VF) was conducted while the patient was in a reclined position. In the oral cavity, when the bolus reached the posterior tongue section, the flow was hindered by the functional obstruction caused by the tongue base pressing against the palate. Despite the clinician's instructions to swallow, the patient was unable to comply due to the severity of his cognitive impairment. To alleviate this obstruction, the clinician pinched the patient's nose. This action opened the fauces, facilitating breathing and relieving the functional obstruction. Subsequently, the bolus flowed into the pharyngeal cavity and successfully flowed into the esophagus while swallowing. This maneuver was named the "pinching nose maneuver" (PNM). The PNM, as described here, can serve as a technique to improve the movement of an intraoral bolus into the pharyngeal cavity in patients with cognitive dysfunction.

The term "Osmotic Demyelination Syndrome" (ODS) is synonymous with central pontine myelinolysis (CPM), denoting a condition characterised by brain damage, particularly affecting the white matter tracts of the pontine region. This damage arises due to the rapid correction of metabolic imbalances, primarily cases of hyponatremia. Noteworthy triggers encompass severe burns, liver transplantations, anorexia nervosa, hyperemesis gravidarum, and hyperglycaemia, all linked to the development of CPM. Clinical manifestations encompass a spectrum of signs and symptoms, including dysphagia, dysarthria, spastic quadriparesis, pseudobulbar paralysis, ataxia, lethargy, tremors, disorientation, catatonia, and, in severe instances, locked-in syndrome and coma. A recent case involving a 45-year-old woman illustrates these complexities. Upon admission to the Medicine Intensive Care Unit, she presented with symptoms indicative of diminished responsiveness and bilateral weakness in the upper and lower limbs. Of significance, the patient had a pre-existing medical history of hyperthyroidism. Extensive diagnostic investigations were undertaken, revealing compelling evidence of profound hyponatremia through blood analyses. Furthermore, magnetic resonance imaging (MRI) was performed, unveiling conspicuous areas of abnormal hyperintensity located in the central pons, intriguingly accompanied by spared peripheral regions. These radiological findings align with the characteristic pattern associated with osmotic demyelination syndrome, illuminating the underlying pathology.
