ABSTRACT
OBJECTIVES@#At present, there are many reports about the treatment of cricopharyngeal achalasia by injecting botulinum toxin type A (BTX-A) into cricopharyngeal muscle guided by ultrasound, electromyography or CT in China, but there is no report about injecting BTX-A into cricopharyngeal muscle guided by endoscope. This study aims to evaluate the efficacy of endoscopic BTX-A injection combined with balloon dilatation in the treatment of cricopharyngeal achalasia after brainstem stroke, and to provide a better method for the treatment of dysphagia after brainstem stroke.@*METHODS@#From June to December 2022, 30 patients with cricopharyngeal achalasia due to brainstem stroke were selected from the Department of Rehabilitation Medicine, the First Hospital of Changsha. They were randomly assigned into a control group and a combined group, 15 patients in each group. Patients in both groups were treated with routine rehabilitation therapy, while patients in the control group were treated with balloon dilatation, and patients in the combined group were treated with balloon dilatation and BTX-A injection. Before treatment and after 2 weeks of treatment, the patients were examined by video fluoroscopic swallowing study, Penetration-aspiration Scale (PAS), Dysphagia Outcome Severity Scale (DOSS), and Functional Oral Intake Scale (FOIS) were used to assess the swallowing function.@*RESULTS@#In the combined group, 1 patient withdrew from the treatment because of personal reasons. Two weeks after treatment, the scores of DOSS, PAS, and FOIS in both groups were better than those before treatment (all P<0.01), and the combined group was better than the control group (all P<0.001). The effective rate was 85.7% in the combined group and 66.7% in the control group, with no significant difference between the 2 groups (P>0.05).@*CONCLUSIONS@#BTX-A injection combined with balloon dilatation is more effective than balloon dilatation alone in improving swallowing function and is worthy of clinical application.

OBJECTIVE@#To establish a predictive model for severe swallowing disorder after acute ischemic stroke based on nomogram model, and evaluate its effectiveness.@*METHODS@#A prospective study was conducted. The patients with acute ischemic stroke admitted to Mianyang Central Hospital from October 2018 to October 2021 were enrolled. Patients were divided into severe swallowing disorder group and non-severe swallowing disorder group according to whether severe swallowing disorder occurred within 72 hours after admission. The differences in general information, personal history, past medical history, and clinical characteristics of patients between the two groups were compared. The risk factors of severe swallowing disorder were analyzed by multivariate Logistic regression analysis, and the relevant nomogram model was established. The bootstrap method was used to perform self-sampling internal validation on the model, and consistency index, calibration curve, receiver operator characteristic curve (ROC curve), and decision curve were used to evaluate the predictive performance of the model.@*RESULTS@#A total of 264 patients with acute ischemic stroke were enrolled, and the incidence of severe swallowing disorder within 72 hours after admission was 19.3% (51/264). Compared with the non-severe swallowing disorder group, the severe swallowing disorder group had a higher proportion of patients aged of ≥ 60 years old, with severe neurological deficits [National Institutes of Health stroke scale (NIHSS) score ≥ 7], severe functional impairments [Barthel index, an activity of daily living functional status assessment index, < 40], brainstem infarction and lesions ≥ 40 mm (78.43% vs. 56.81%, 52.94% vs. 28.64%, 39.22% vs. 12.21%, 31.37% vs. 13.62%, 54.90% vs. 24.41%), and the differences were statistically significant (all P < 0.01). Multivariate Logistic regression analysis showed that age ≥ 60 years old [odds ratio (OR) = 3.542, 95% confidence interval (95%CI) was 1.527-8.215], NIHSS score ≥ 7 (OR = 2.741, 95%CI was 1.337-5.619), Barthel index < 40 (OR = 4.517, 95%CI was 2.013-10.136), brain stem infarction (OR = 2.498, 95%CI was 1.078-5.790) and lesion ≥ 40 mm (OR = 2.283, 95%CI was 1.485-3.508) were independent risk factors for severe swallowing disorder after acute ischemic stroke (all P < 0.05). The results of model validation showed that the consistency index was 0.805, and the trend of the calibration curve was basically consistent with the ideal curve, indicating that the model had good prediction accuracy. ROC curve analysis showed that the area under the ROC curve (AUC) predicted by nomogram model for severe swallowing disorder after acute ischemic stroke was 0.817 (95%CI was 0.788-0.852), indicating that the model had good discrimination. The decision curve showed that within the range of 5% to 90%, the nomogram model had a higher net benefit value for predicting the risk of severe swallowing disorder after acute ischemic stroke, indicating that the model had good clinical predictive performance.@*CONCLUSIONS@#The independent risk factors of severe swallowing disorder after acute ischemic stroke include age ≥ 60 years old, NIHSS score ≥ 7, Barthel index < 40, brainstem infarction and lesion size ≥ 40 mm. The nomogram model established based on these factors can effectively predict the occurrence of severe swallowing disorder after acute ischemic stroke.

Two phases were included in the study. In the first phase of study, the therapeutic effect was compared among the three acupuncture groups, named C1, C2 and C3 group, so as to screen the optimal acupuncture regimen. In the group C1, the main acupoints included Fengchi (GB 20), Wangu (GB 12), Yifeng (TE 17) and three-tongue points (Extra). In the group C2, the main acupoints were Neiguan (PC 6), Tongli (HT 5), Zusanli (ST 36) and Sanyinjiao (SP 6) as well as the supplementary acupoints in accordance with the syndrome differentiation. In the group C1 and group C2, after , the electroacupuncture was used, with continuous dense wave, 5 to 8 Hz in frequency. The needles were retained for 30 min. Acupuncture was given once a day, 5 treatments a week. Before treatment, in 6 weeks of treatment or after removal of gastric tube, the rehabilitation was evaluated. In the group C3, the acupoints, manipulation and treating course were same as the group C1 and group C2. In the 2nd phase of study, theresults of rehabilitation treatment were compared among the group A, group B and group D. The treatment was given once a day, 5 times a week. Before treatment, after gastric tube removal or in 6 weeks of treatment, the evaluation was conducted. The feedingswallowing function grade and VFSS were adopted in the evaluation among the above 6 groups.@*RESULTS@#① In the VFSS comparison at 1st phase of study after treatment, the food transporting ability at oral dysphagia, the results in the group C3 and group C1 were better obviously than the group C2 (both 0.05). The severity of dysphagia in the group C3 was milder than the group C2 and group A (both <0.05). ② In the VFSS comparison at the 2nd phase of study, for the food transporting ability, the results in the group D and the group B were obviously better than the group A (both <0.05). Regarding the function at the pharyngeal dysphagia and aspiration, the results in the group D were better than the group B and group A, those in the group B were better than the group A (all <0.05). The difference in the extubation rate among the group A, group B and group D after treatment was significant statistically (<0.01), of which, the extubation rate in the group D was the highest and the rate in the group A was the lowest. The dysphagia degree in the group D was milder than the group B and group A and that in the group B was milder than the group A (all <0.05).@*CONCLUSION@#In the study of the different acupuncture methods, the acupuncture at the local acupoints and the acupoints selected based on differentiation is the optimal acupuncture regimen for cricopharyngeal achalasia after brain stem infarction.

OBJECTIVE: Cerebral varices (CVs) without an arteriovenous shunt, so called nonfistulous CVs, are very rare, and their etiology and natural course are not well understood. The aim of this study is to evaluate the clinical outcomes of nonfistulous CVs by the analysis of 39 cases. METHODS: From 2000 to 2015, 22 patients with 39 nonfistulous CVs (≥5 mm) were found by searching the medical and radiologic records of our institute. Clinical data and radiological data including numbers, sizes and locations of CVs and associated anomalies were retrospectively collected and analyzed. Previously reported cases in literature were reviewed as well. RESULTS: The mean age of the patients was 21 years (range, 0–78 years). On average, 1.8±1.2 CVs were found per patient. CVs were categorized as either fusiform or saccular depending on their shapes. Two patients had saccular type CVs, seventeen patients had fusiform types, and three patients had both fusiform and saccular CVs. Eight patients had associated compromise of the vein of Galen and the straight sinus. Four of those patients had sinus pericranii, as well. Five patients had CVs that were distal draining veins of large developmental venous anomalies. One patient had associated migration anomaly, and two patients had Sturge- Weber syndrome. Six patients with an isolated cerebral varix were observed. Of the 39 CVs in 22 patients, 20 lesions in 14 patients were followed up in outpatient clinics with imaging studies. The average follow-up duration was 6.6 years. During this period, no neurological events occurred, and all the lesions were managed conservatively. CONCLUSION: Nonfistulous CVs seemed to be asymptomatic in most cases and remained clinically silent. Hence, we suggest conservative management.

BACKGROUND AND PURPOSE: Subclinical atherosclerotic plaques are common in patients with pontine infarctions (PIs) but without basilar artery (BA) stenosis. We hypothesized that BA plaque locations may differ by PI type and vertical location as well as vertebrobasilar artery geometry. METHODS: Ninety-six patients with PI but without BA stenosis on magnetic resonance imaging (MRI) and magnetic resonance angiography were enrolled. PIs were classified by type (paramedian, deep, or lateral) and vertical location (rostral, middle, or caudal). Patients underwent high-resolution MRI to evaluate BA plaque location (anterior, posterior, or lateral). The mid-BA angle on anteroposterior view and angle between the BA and dominant vertebral artery (BA-VA angle) on lateral view were measured. RESULTS: The PIs were paramedian (72.9%), deep (17.7%), and lateral (9.4%) type with a rostral (32.3%), middle (42.7%), and caudal (25.0%) vertical location. The BA plaque locations differed by PI type (P=0.03) and vertical location (P < 0.001); BA plaques were most frequent at the posterior wall in paramedian (37.1%) and caudal (58.3%) PIs and at the lateral wall in lateral (55.5%) and middle (34.1%) PIs. The BA-VA and mid-BA angles differed by BA plaque and PI vertical location; the greatest BA-VA angle was observed in patients with posterior plaques (P < 0.001) and caudal PIs (P<0.001). Greatest mid-BA angles were observed with lateral BA plaques (P=0.03) and middlelocated PIs (P=0.03). CONCLUSIONS: Greater mid-BA angulation may enhance lateral plaque formation, causing lateral and middle PIs, whereas greater BA-VA angulation may enhance posterior plaque formation, causing paramedian or caudal PIs.

Top of the basilar (TOB) syndrome occurs with occlusion of the rostral portion of the basilar artery that supplies blood to the midbrain, thalamus, and temporal and occipital lobes. Symptoms associated with TOB include decreased alertness, abnormal eye movement, dysarthria, and disorders of cerebellar function. A 47-year-old man was transferred to our hospital to manage C2 vertebral fracture sustained in a traffic accident. He was alert on arrival; however, he lapsed into semicoma. He was diagnosed with TOB. Thrombolytic agents could not be administered due to a contraindication in cervical spine fracture. Brain magnetic resonance imaging showed acute infarction of the pons, cerebellum, and posterior cerebral artery territory. This rare case demonstrates that C2 vertebral fracture can result in TOB.

Acute peripheral facial palsy usually manifests Bell's palsy of unknown cause, and rarely lacunar infarct which located in facial nucleus can mimic peripheral facial palsy. A 73 year-old man with isolated facial asymmetry diagnosed with lacunar infarction which selectively involve the facial fascicles which lie in inferolateral aspect of pons. Clinicians should take into account the possibility of central lesion and brain stem infarction, even when patients present with isolated peripheral type facial palsy.

The clinical manifestations of vertebral artery (VA) injury (VAI) after cervical trauma range from asymptomatic to fatal cerebral infarction. Thrombotic occlusion and embolization to the distal arteries can cause cerebellar and brain stem infarction within days after trauma. We report a 64-year-old man who underwent arthrodesis surgery for C1 and C2 fractures. He had left VAI at the C2 transverse foramen site but was asymptomatic. The patient experiences brainstem and cerebellar infarction 3 months after injury to the VA, and we are here to discuss the treatment of VAI after cervical trauma.

The waffle-cone technique is a modified stent application technique, which involves protrusion of the distal portion of a stent into an aneurysm fundus to provide neck support for subsequent coiling. The authors report two cases of wide necked basilar bifurcation aneurysms, which were not amenable to stent assisted coiling, that were treated using the waffle-cone technique with a Solitaire AB stent. A 58-year-old woman presented with severe headache. Brain CT showed subarachnoid hemorrhage and angiography demonstrated a ruptured giant basilar bifurcation aneurysm with broad neck, which was treated with a Solitaire AB stent and coils using the waffle-cone technique. The second case involved an 81-year-old man, who presented with dizziness caused by brain stem infarction. Angiography also demonstrated a large basilar bifurcation unruptured aneurysm with broad neck. Solitaire AB stent deployment using the waffle-cone technique, followed by coiling resulted in near complete obliteration of aneurysm. The waffle-cone technique with a Solitaire AB stent can be a useful alternative to conventional stent application when it is difficult to catheterize bilateral posterior cerebral arteries in patients with a wide-necked basilar bifurcation aneurysm.

Lateral medullary infarction can lead to central respiratory failure. However, in Wallenberg's syndrome, obstructive respiratory failure rarely develops. Here, we report a case of obstructive respiratory failure with stridor caused by unilateral lateral medullary infarction. A 74-year-old woman was admitted for acute right lateral medullary infarction. On the 12th day after the stroke, the patient developed respiratory failure necessitating endotracheal intubation. She could maintain good oxygen saturation and ventilation in intubated status without the assistance of mechanical ventilator, even during sleep. The pharyngo-laryngoscopy demonstrated the hypomobility of bilateral vocal cords. This case suggests that unilateral medullary infarction might be a cause of bilateral vocal cord palsy.

PURPOSE: This study aimed to survey the frequency of ischemic stroke mimicking peripheral vertigo (Pseudo-peripheral vertigo), the pattern of clinical presentation and the factors related to it. METHODS: The medical records of 641 patients who were diagnosed with ischemic stroke by brain magnetic resonance imaging (MRI) at the emergency department (ED) between January 2006 and December 2008 were retrospectively reviewed. RESULTS: Approximately 9.5% of patients suffering ischemic stroke presented at the ED with only the symptom of dizziness. The patients were predominantly male (74.2%), age >60 years (62.3%), and 91.2% of patients had multiple stroke risk factors. Cases of cerebral, cerebellar and brain stem infarction were 21.3%, 60.7% and 9.9%, respectively. No abnormal cerebellar function was reported in 44% of patients. All of the patients with typical peripheral vertigo symptoms had two or more stroke risk factors and tested as having normal cerebellar function. CONCLUSION: Of patients with stroke as diagnosed by brain MRI, 9.5% of them had only presented dizziness at the ED. Of the patients mimicking peripheral vertigo, 44% resulted with normal neurologic tests. Thus, evaluation by brain MRI should be considered for patients with stroke risk factors who receive a differential diagnosis of vertigo of central origin.
