In this paper, we propose a multi-scale mel domain feature map extraction algorithm to solve the problem that the speech recognition rate of dysarthria is difficult to improve. We used the empirical mode decomposition method to decompose speech signals and extracted Fbank features and their first-order differences for each of the three effective components to construct a new feature map, which could capture details in the frequency domain. Secondly, due to the problems of effective feature loss and high computational complexity in the training process of single channel neural network, we proposed a speech recognition network model in this paper. Finally, training and decoding were performed on the public UA-Speech dataset. The experimental results showed that the accuracy of the speech recognition model of this method reached 92.77%. Therefore, the algorithm proposed in this paper can effectively improve the speech recognition rate of dysarthria.

INTRODUCTION:
The National Institutes of Health Stroke Scale (NIHSS), originally designed in the United States of America, contains items on dysphasia and dysarthria that are deemed culturally unsuitable for the Singapore context. We compared the error rates of dysphasia objects, dysphasia phrases and dysarthria words between the original and alternative items in a cohort of Singaporean subjects without dysphasia or dysarthria.
METHODS:
In this prospective study, 140 English-speaking Singaporean subjects without impairments of dysphasia or dysarthria had an assessment of NIHSS items 9 and 10 using the original and alternative items. Paired analyses were conducted for comparison of error rates.
RESULTS:
The error rates were high for four original dysphasia objects (Hammock: 62.9%, Cactus: 38.6%, Feather: 23.6%, Glove: 20.7%) and significantly lower for alternative items (Snail: 5%, Horse: 1.4%, Hanger: 1.4%, Car: 0%) (P < 0.001). For dysphasia phrases and dysarthria words, the error rates were low and there were no differences in error rates between the original and alternative items.
CONCLUSION
There are cultural issues with several dysphasia objects in the original NIHSS as evidenced by the high error rates, which were lowered with more culturally suitable alternatives. This study formed a basis to derive a more suitable version of the NIHSS for English-speaking subjects in Singapore.

A boy, aged 2 years and 4 months, had a sudden onset of blepharoptosis of the right eyelid, accompanied by the mouth deviated to the right side, drinking cough, nystagmus, and developmental regression. Cranial MRI showed softening lesions formed after infarction of the right dorsolateral medulla oblongata, while head CT angiography showed no imaging of the proximal part of the V4 segment of the right vertebral artery. The child was diagnosed with dorsolateral medulla oblongata syndrome and was treated with gamma globulin to regulate immune function, with mannitol to reduce neuronal edema, with low-molecular-weight heparin sodium to improve local hypercoagulation of occluded blood vessels, with hyperbaric oxygen to improve local ischemia and hypoxia and promote the recovery of brain function, and with neuromuscular electrical stimulation to promote the recovery of neuromuscular function. Before discharge, only mild right ataxia and Horner syndrome remained. This article reports the first case of infantile dorsolateral medulla oblongata syndrome and provides experience for the diagnosis and treatment of the disease.

Supratentorial extraventricular anaplastic ependymoma (SEAE) in adults is a relatively rare intracranial tumor. Because of the very low prevalence, only a few cases have been reported. According to a recent study, SEAE is associated with a poor prognosis and there is no definite consensus on optimal treatment. We report a case of an adult SEAE patient who had no recurrence until seven years after a gross total resection (GTR) followed by conventional radiotherapy. A 42-year-old male had a persistent mild headache, left facial palsy, dysarthria, and left hemiparesis. Preoperative neuroimaging revealed an anaplastic astrocytoma or supratentorial ependymoma in the right frontal lobe. A GTR was performed, followed by adjuvant radiotherapy. Histologic and immunohistochemical results revealed anaplastic ependymoma. After seven years of initial therapy, a regular follow-up MRI showed a 3-cm-sized partially cystic mass in the same area as the initial tumor. The patient underwent a craniotomy, and a GTR was performed. Histopathologic examination revealed recurrence of the SEAE. External radiotherapy was performed. The patient has been stable without any disease progression or complications for 12 months since the surgery for recurrent SEAE.

We describe a 33-year-old woman with chronic bulbar dysarthria after ischemic brainstem stroke who underwent a new form of constraint-induced therapy, namely constraint-induced dysarthria therapy, based on three principles: avoidance of supportive devices, intensive therapy, and gradually augmenting difficulty. After a 2-month intervention, improvement was noted for speech intelligibility, fluency, and intensity. This led to increased communicative participation, including during conversation situations, which has been maintained over a 12-month follow-up.

Macroglossia is a rare clinical condition defined as an enlarged tongue. Macroglossia can cause structural deformities like diastema and disproportionate mandibular growth and present functional disorders such as dysarthria, dysphonia, and respiratory problems. A 7-year-old boy who had lymphangiomatous macroglossia was treated with a reduction glossectomy by anchor-shaped combination of a U-shape and modified key-hole resection. Postoperatively, the reduced tongue was contained completely within the oral cavity, but open bite remained due to prognathism. Sensory and motor nerves to the tongue appeared to be intact, and circulation was adequate. This patient will be monitored for recurrence of tongue enlargement.

OBJECTIVE:
To systematically evaluate the clinical efficacy of acupuncture for dysarthria, and to explore the rules of acupoints selection for dysarthria.
METHODS:
The clinical randomized control trial literature regarding acupuncture for dysarthria published before January of 2018 were searched in databases, including CNKI, Wanfang, VIP, CBM, PubMed, Ebsco, Science Direct and Cochrane Library. The information of included studies was extract and the quality was assessed. The Meta analysis was performed by using RevMan 5.3 software. The frequency of acupoints was calculated by using Excel software to analyzed the rules of acupoints selection.
RESULTS:
Totally 21 papers were included, involving 1651 patients. The pooled effects of clinical efficacy: heterogeneity test =0.74, =0%, =6.36, 95% CI: 4.55, 8.88, =10.84 (<0.01), indicating the efficacy in the treatment group was significantly higher than that in the control group. The pooled effects of the symptom score in Frenchay scale: heterogeneity test =0.56, =0%, =3.20, 95% CI: 1.38, 5.02, =3.45 (<0.01), indicating the efficacy in the treatment group was significantly higher than that in the control group. The acupoints with frequency of more than 5 times were Fengchi (GB 20), Yuye (EX-HN 13), Jinjin (EX-HN 12), Lianquan (CV 23), Baihui (GV 20), tongue-three needles and Yamen (GV15). The meridians with frequency of more than 5 times were the extra channels, governor vessel, gallbladder channel, conception vessel and stomach channel.
CONCLUSION
The clinical efficacy of acupuncture combined with speech training/regular treatment is significantly superior to that of control group (speech training, medication, regular treatment); acupuncture is safe and effective for dysarthria; the majority of selected acupoint is local acupoints around tongue, throat and neck, as well as extra points and empirical points. However, high-quality randomized controlled trials with large sample sizes are still needed to provide further evidence.

A patient who went through maxillectomy can have soft palate defects including oronasal fistulas and suffer from dysphagia and dysarthria due to velopharyngeal insufficiency. This defect causes the food to enter nasal cavity and creates hypernasal sound which debilitates a quality of life. An obturator can rehabilitate the substantial oral tissue defects. The maxillary obturator separates the nasopharynx from the oropharynx during speech and deglutition by closing of the defect. For edentulous obturator patient, it is difficult to obtain proper retention due to reduced peripheral sealing. Therefore, the contours of the defects must be used to maximize the retention, stability, and support. Hollow type obturator can improve physiologic function by reducing weight than the traditional obturator. This case report describes a patient with hemi-maxillectomy who recovers mastication, speech, deglutition, and appearance with a maxillary obturator using physiological border molding of the velopharyngeal area and double-processing method.

A complicated case of echinococcosis with multiple organ involvement is reported in a 53-year-old businessman who frequently traveled overseas, including China, Russia, and Kazakhstan from 2001 to 2007. The patient was first diagnosed with a large liver cyst during a screening abdomen ultrasonography in 2011, but he did not follow up on the lesion afterwards. Six years later, dizziness, dysarthria, and cough developed, and cystic lesions were found in the brain, liver and lungs. The clinical course was complicated when the patient went through multiple surgeries and inadequate treatment with a short duration of albendazole without a definite diagnosis. The patient visited our hospital for the first time in August 2018 due to worsening symptoms; he was finally diagnosed with echinococcosis using imaging and serologic criteria. He is now on prolonged albendazole treatment (400 mg twice a day) with gradual clinical and radiological improvement. A high index of suspicion is warranted to early diagnose echinococcosis in a patient with a travel history to endemic areas of echinococcosis.

Direct puncture and embolization of the transverse sinus (TS) for treatment of dural arteriovenous fistula (DAVF) is typically performed with coils with or without glue. We report a case of DAVF at the left TS that was treated with Onyx embolization via direct puncture of the TS. A 75-year-old woman presented with tremor, festinating gait, and dysarthria. A left TS-DAVF with retrograde superior sagittal sinus and cortical venous reflux (Cognard type IIa+b) was identified on cerebral angiography, and both TSs were occluded with thrombi. We considered that achieving complete cure by transvenous embolization via the femoral vein or transarterial embolization via occipital feeders would be difficult. Thus, we performed a small craniotomy at the occipital bone to puncture the TS. The midportion of the TS was directly punctured with a 21-G microneedle under fluoroscopic guidance. We inserted a 5-F sheath into the TS. A microcatheter was then navigated into the affected sinus. Coils were placed through the microcatheter to support Onyx formation by reducing the pressure of shunting flow. Onyx embolization was performed with the same microcatheter. The DAVF was almost completely occluded except for the presence of minimal shunting flow to the proximal TS. After 1 week, time-of-flight magnetic resonance angiography showed complete resolution of DAVF. The patient showed resolved tremor and markedly improved mental status at 1-month follow up. Direct puncture and embolization of the TS using coils and Onyx is effective and feasible method for the treatment of DAVF when other approaches seem difficult.
