Brown-Vialetto-Van Laere syndrome (BVVLS) is a rare neurodegenerative disorder of childhood. According to the previous reports, it has various primary signs and symptoms. Because of the simple treatment with riboflavin supplementation, it is important to have suspicious to this disease and begin treatment even before genetic test confirm. We report a five-year-old girl with BVVLS that manifest with hearing problems, first. There was obvious improvement in her disease clinical signs with riboflavin supplementation treatment.

INTRODUCTION. Effective kinesitherapy of peripheral and central paralysis of the mimic, masticatory, lingual and pharyngeal muscles requires in-depth study of the features of the cooperative work of these muscles in the norm and in pathology. AIM. To acquaint rehabilitation specialists with motor automatisms of the brachiofacial area and show the principles of their practical use. MATERIAL AND METHODS. We studied more than 70 literature sources on involuntary activity of the maxillofacial region and adjacent regions muscles as well as we summarized our own experience in rehabilitation of patients with peripheral facial neuropathies and with bulbar and pseudobulbar syndromes RESULTS AND DISCUSSION. The study showed that the face, neck, and arm are involved in various mesencephalic-bulbar automatisms, both normal (ontogenetic and psychosomatic synkinesia, postural-ocular and postural-mandibular reflexes) and pathological (trunk eye-facial synkinesia, oral automatic reflexes), much more closely than other body parts. All of them, with the exception of facial hyperkinesias, may serve as a basis for optimizing kinesitherapy methods for movement disorders of the brachiofacial region. CONCLUSION. The face, neck, and hand are closely involved in a variety of stem and subcortical automatisms. The better the physical therapist is familiar with the features of the existing or potentially available to the patient reflex activity in the part of the body being rehabilitated, the more effective the rehabilitation treatment will be. The face, neck and arm are closely involved in a variety of stem and subcortical automorphisms. The better a doctor or an instructor in exercise therapy is acquainted with the reflex activity present or potentially available in the part of the body to be rehabilitated, the more effective the rehabilitation treatment will be.

Background: Brainstem cavernomas (BSCs) are relatively rare intracranial vascular lesions that, if left untreated, can be devastating to the patient. The lesions are associated with a myriad of symptoms, depending on their size and location. However, medullary lesions present acutely with cardiorespiratory dysfunction. We present the case of a 5-month-old child with a BSC. Case Description: A 5-month-old child presented for the 2nd time with sudden respiratory distress and excessive salivation. On the first presentation, brain magnetic resonance imaging (MRI) showed a 13 × 12 × 14 mm cavernoma at the pontomedullary junction. She was managed conservatively but presented 3 months later with tetraparesis, bulbar palsy, and severe respiratory distress. A repeat MRI showed enlargement of the cavernoma to 27 × 28 × 26 mm with hemorrhage in different stages. After hemodynamic stabilization, complete cavernoma resection was performed through the telovelar approach with neuromonitoring. Postoperatively, the child recovered motor function, but the bulbar syndrome persisted with hypersalivation. She was discharged on day 55 with a tracheostomy. Conclusion: BSCs are rare lesions that are associated with severe neurological deficits due to the compactness of important cranial nerve nuclei and other tracts in the brainstem. Early surgical excision and hematoma evacuation for superficially presenting lesions can be lifesaving. However, the risk of postoperative neurological deficits is still a major concern in these patients. [ABSTRACT FROM AUTHOR]

Abstract Background Compared with typical bulbar onset amyotrophic lateral sclerosis (ALS), isolated bulbar palsy (IBP), an often under-understood variant of ALS, is characterized by symptoms confined to bulbar region for extended periods and relative preservation of limb and ventilation function. To find a cutoff value of disease duration that can distinguish IBP from typical bulbar onset ALS well, the association of survival with disease progression in bulbar onset ALS patients was analyzed. Methods Clinical data of bulbar onset ALS patients were collected from January 2009 to December 2013. The duration from bulbar onset to first significant limb involvement was analyzed by a cutoff point analysis with maximally selected log-rank statistics and dichotomized to categorize patient outcomes. The patients were divided into two groups, the IBP and typical bulbar onset ALS groups, according to the cutoff value. Clinical features were compared. Results 115 bulbar onset ALS patients were recruited, and the duration from bulbar onset to first significant limb involvement was associated with survival (P

Anti-amphiphysin antibody is a rare paraneoplastic autoantibody. A case of a 74-year-old man with anti-amphiphysin antibody and multiple symptoms, including bulbar palsy along with cerebellar ataxia, who responded to treatment with intravenous cyclophosphamide is reported. The patient presented with progressive unsteady gait and difficulty in swallowing food and water for three months. On admission, he had severe ataxia, downbeat and horizontal nystagmus, dysarthria, dysphagia, loss of tendon reflexes, and dysuria. Anti-amphiphysin antibodies were detected in the serum, resulting in the diagnosis of non-stiff anti-amphiphysin syndrome. No significant abnormalities were observed in imaging studies of the brain and the whole body. The patient was treated with high-dose intravenous immunoglobulin and steroids, yielding only slight improvement. After two courses of intravenous cyclophosphamide pulse therapy, his neurological symptoms, notably dysphagia and cerebellar ataxia, improved. Follow-up computed tomography and fluorodeoxyglucose-positron emission tomography/computed tomography showed enlarged mediastinal lymph nodes and hypermetabolic uptake of F-18 fluorodeoxyglucose six months after the onset of the neurological symptoms. Histological examination of a lymph node showed metastatic small cell lung cancer. This case highlights the efficacy of cyclophosphamide as second-line immunotherapy for anti-amphiphysin syndrome., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

BackgroundBrown-Vialetto-Van Laere Syndrome (BVVLS), a rare neurological disorder characterized by bulbar palsies and sensorineural deafness, is mainly associated with defective riboflavin transporters encoded by the SLC52A2 and SLC52A3 genes.MethodsHere we present a 16-year-old BVVLS patient belonging to a five generation consanguineous family from Indian ethnicity with two homozygous missense mutations viz., c.421C>A [p.P141T] in SLC52A2 and c.62A>G [p.N21S] in SLC52A3.ResultsFunctional characterization based on 3H-riboflavin uptake assay and live-cell confocal imaging revealed that the effect of mutation c.421C>A [p.P141T] identified in SLC52A2 had a slight reduction in riboflavin uptake; on the other hand, the c.62A>G [p.N21S] identified in SLC52A3 showed a drastic reduction in riboflavin uptake, which appeared to be due to impaired trafficking and membrane targeting of the hRFVT-3 protein.ConclusionsThis is the first report presenting mutations in both riboflavin transporters hRFVT-2 and hRFVT-3 in the same BVVLS patient. Also, c.62A>G [p.N21S] in SLC52A3 appears to contribute more to the disease phenotype in this patient than c.421C>A [p.P141T] in SLC52A2.

Abstract Amyloidosis, a disease with extracellular tissue deposition of fibrils, results in clinical manifestations based on deposition of these fibrils in multiple organ systems. Usual manifestations include nephrotic‐range proteinuria, cardiac failure, hepatosplenomegaly, and skin manifestations. Common neurological manifestations include peripheral and autonomic neuropathies. Cranial neuropathy has been seldom reported and is an unusual clinical feature of amyloidosis. Here, we report an older man who presented with cranial nerve palsies along with other clinical features, including heart failure, proteinuria, weight loss, anorexia and distal symmetric polyneuropathy and was diagnosed with immunoglobulin light‐chain (AL) amyloidosis.

BackgroundSince the outbreak of West Nile virus (WNV) in the United States in 1999, the WNV neuroinvasive disease has been increasingly reported with a wide spectrum of neuromuscular manifestations.CaseWe submit a case of a 46-year-old male with a history of alcohol abuse, diabetes, hypertension, and hepatitis C who presented with fever, nausea, shortness of breath, and dysphagia. The patient rapidly developed hypercapnic respiratory failure and was found to have WNV meningoencephalitis without obvious neuromuscular weakness. His hospital course was significant for repeated failures of extubation secondary to persistent bulbar weakness eventually requiring tracheotomy.ConclusionThis is a unique case of WNV meningoencephalitis with bulbar palsy without other neuromuscular manifestations resulting in recurrent hypercapnic respiratory failure.

To find a cutoff value of disease duration that can distinguish IBP from typical bulbar onset ALS well, the association of survival with disease progression in bulbar onset ALS patients was analyzed.Methods: Clinical data of bulbar onset ALS patients were collected from January 2009 to December 2013. The duration from bulbar onset to first significant limb involvement was analyzed by a cutoff point analysis with maximally selected log-rank statistics and dichotomized to categorize patient outcomes. The patients were divided into two groups, the IBP and typical bulbar onset ALS groups, according to the cutoff value. Clinical features were compared.Results: 115 bulbar onset ALS patients were recruited, and the duration from bulbar onset to first significant limb involvement was associated with survival (P < 0.001). The cutoff duration was 20 months. 19 patients were identified as IBP and 96 patients as typical bulbar onset ALS using 20 months as the cutoff duration. Female was more common, limb weakness was less frequent and pure upper motor neuron (UMN) bulbar signs were more frequent in the IBP group than in the typical bulbar onset ALS group (P = 0.047; P = 0.004; P = 0.031). The median survival time of the IBP group was significantly longer than that of the typical bulbar onset ALS group (64 months and 26 months, respectively; P < 0.001).Conclusions: A cutoff duration of 20 months from bulbar onset to first significant limb involvement may be used to specifically distinguish IBP from typical bulbar onset ALS. IBP was characterized by female predominance, relative preservation of limb function, more pure UMN bulbar signs and a relatively benign prognosis. [ABSTRACT FROM AUTHOR]

Objective: To describe the clinical-laboratory profile of pediatric Guillain-Barre syndrome and delineate features associated with need of mechanical ventilation. Methods: In a prospective observational study at tertiary care hospital, clinical-laboratory assessment and nerve conduction studies were documented in consecutive children hospitalized with Guillain-Barre syndrome according to Brighton criteria. Clinical-laboratory features were compared between ventilated and nonventilated patients using univariate and multivariate analysis. Results: Forty-six children (27 boys) with a mean age of 69.1±35.2 months were enrolled. History of preceding infection was present in 47.8%, bulbar palsy in 43.5%, feeble voice in 41.3%, sensory involvement in 13%, and autonomic involvement in 39.5%. Tetraparesis was noted in 87% of cases. Hughes disability scale >3 was noted in 44 children at admission and 39 (84.7%) at discharge. The most common electrophysiological type was acute motor axonal neuropathy (46.5%) followed by acute motor sensory axonal neuropathy (39.5%), acute inflammatory demyelinating polyneuropathy (7%), and inexcitable nerves (7%). Nine (19.7%) children were ventilated, 3 (6.5%) died or were lost, and 43 were discharged. Factors associated with need of mechanical ventilation on univariate analysis were older age, hypertension, bulbar palsy, feeble voice, lower Medical Research Council (MRC) sum, raised total leucocyte count, and history of preceding infection. Logistic regression revealed older age, history of predisposing illness, lower MRC sum at presentation, and bulbar palsy as independent predictors of mechanical ventilation. Conclusions: The most common electrophysiological subtype in northern Indian children is acute motor axonal neuropathy. Older age, preceding infection, low MRC sum, and bulbar palsy are predictors of mechanical ventilation in pediatric Guillain-Barre syndrome. [ABSTRACT FROM AUTHOR]

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an adult-onset inherited small vessel disease of the brain caused by NOTCH3 mutations. Clinical characteristics of CADASIL include recurrent infarctions, migraine with aura, mood disturbances and cognitive impairment. We report a 35 year-old migraine-free patient with unusual presentation with acute simultaneous multiple subcortical infarctions causing progressive bulbar palsy as the initial manifestation. Hepresented with slurred speech progressing to anarthria and bilateral palsy of lower motor cranial nerves within 24 hour. Initial acute subcortical infarcts enlarged and new infarcts developed in bilateral hemispheres. There was diffuse leukoencephalopathy involving temporal horns and the patient had positive familiy history of migraine and young stroke. CADASIL was diagnosed genetically when NOTCH3 mutationwas shown. The patient improved after treatment with liquid hydration and antiplatelet agent. We experienced with the patient that CADASIL may present with unusual progressive manifestations and bilateral simultaneous infarctions. Irrespective of clinical presentation, patients with leukoencephalopathy and positive familiy history should be tested for NOTCH3 mutation.

Objectives: Isolated bulbar palsy (IBP) is a rare variant that can show a benign course, while progressive bulbar palsy (PBP) has been regarded as a bulbar-dominant type of classical amyotrophic lateral sclerosis (cALS). This study aimed to identify differences in the excitability properties between them. Methods: We consecutively collected data on 22 ALS patients: 13 with cALS, 5 with PBP, and 4 with IBP. An automated nerve excitability test (NET) was applied to measure the strength–duration time constant, threshold electrotonus (TE), current–threshold relationship, and recovery cycle. The axonal excitability properties were compared between the ALS groups and 25 controls. Results: Compared to controls, the cALS group showed a greater change in the depolarizing phase of TE of 90–100 ms after depolarizing current [TEd(90–100)] (53.3±1.3 [mean±SEM] for cALS and 49.0±0.7 for control, P<0.01) and lower S2 accommodation (19.6±0.8 and 22.6±0.7, respectively; P=0.01). There was a nonsignificant tendency for a high TEd(90–100) pattern to be less prominent in the IBP group than in the PBP group (51.5±4.22 and 48.8±1.5, respectively). In addition, all of the parameters of nerve excitability other than S2 accommodation in the PBP and IBP groups did not differ significantly from those in the controls. Conclusions: The excitability properties of IBP and PBP differ from those of cALS. The pattern of NET in PBP was more similar to that in cALS than that in IBP. These findings suggest that IBP is a different entity from bulbar-dominant ALS and PBP. [ABSTRACT FROM AUTHOR]

Background: Respiratory derangement is a major health hazard in patients with neuromuscular disorders (NMD). This study aimed to compare spirometry results using facemask with that of conventional tube in patients with NMD and accordingly possible use of facemask instead of conventional tube in this group of patients. Methods: Thirty-six patients with NMD and fifty normal volunteers were recruited within 9 months. Assessment of patients included history and physical examination specially presence of respiratory symptoms, duration and stage of neuromuscular illness, bulbar symptoms, sensory, motor and cranial nerve assessment. Then all participants were subjected to spirometry and respiratory pressures assessment using both conventional tube and facemask. Results: Spirometry and respiratory pressure assessment using facemask versus tube measured in all participants. For patients with NMD; spirometric measures PImax and PEmax were higher in tube than facemask. FEV1, FEV1%, FEV1/FVC %, and PImax showed statistically significant difference. For patients with bulbar palsy; SVC was higher in facemask without statistically significant difference. For other spirometric measures, PImax and PEmax; using tube was higher than facemask with only FEV1, FEV1% showed statistically significant difference (p = 0.023 and 0.015 respectively). For patients without bulbar palsy; all spirometric measures, PImax and PEmax were higher when using tube with only FEV1/FVC % showed statistically significant difference (p = 0.004). Also for control group; data were higher in tube with only FEV1 showed statistically significant difference (p = 0.031). For patients with NMD; fractional functional defect (FFD) was very high for PImax and PEmax. Conclusion: The use of facemask during assessment of spirometric and respiratory pressures measures in patients with NMD and more specifically in patients with bulbar palsy is promising and can be considered a good alternative to conventional tube assessment for functional screening rationale.

This case report describes a successfully managed rare variant of Guillain-Barre´ Syndrome (GBS), the pharyngeal-cervical-brachial (PCB) variant, in a 5-year-old child which is characterized by the involvement of oropharyngeal, neck and upper limb muscles, without disturbed consciousness or ataxia. Since early treatment and supportive care yield successful outcome, it is important for the treating physician to be familiar with other diseases that mimic the disease and variants for prompt and accurate diagnosis.

Background: Progressive bulbar palsy (PBP) is a classic phenotype of bulbar onset amyotrophic lateral sclerosis (ALS) with more rapid progression and worse prognosis. However, as an often under-understood variant of ALS, isolated bulbar palsy (IBP) appears to progress more slowly and has a relatively benign prognosis. This study aimed to investigate the natural course and clinical features of IBP in Chinese population and to compare them with those of PBP. Methods: The clinical data of patients with bulbar onset ALS were collected from January 2009 to December 2013. Revised ALS Functional Rating Scale (ALSFRS-R), forced vital capacity (FVC), and follow-up evaluation were performed, and the differences in basic clinical features, ALSFRS-R, FVC, and primary outcome measures between IBP and PBP were analyzed. The independent t-test, Chi-square test, Mann-Whitney U-test, and Kaplan-Meier analysis were used. Results: Totally 154 patients with bulbar onset ALS were categorized into two groups, 33 with IBP and 121 with PBP. In the IBP group, the male to female ratio was 0.7 to 1.0, and the mean onset age was 58.5 years. The mean duration from the onset was 16.0 months, and the mean ALSFRS-R score was 43.4 at patients' first visit to our hospital. In 14 IBP patients performing FVC examination, the mean FVC value was 90.5% and there were only two cases with abnormal FVC. In 26 IBP patients completing follow-up, 15 (58%) suffered death or tracheotomy and the mean survival time was 40.5 months. Significant differences were noted in sex ratio, onset age, ALSFRS-R score, upper motor neuron limb signs, pure lower motor neuron (LMN) bulbar signs, FVC, and survival time between IBP and PBP. Conclusions: IBP was evidently different from PBP, which was characterized with the predominance of female, pure LMN bulbar signs, an older onset age, a relative preservation of respiratory function, and a better prognosis.

Multiple acyl-CoA dehydrogenase deficiency (MADD), also known as glutaric acidemia type II, is classically caused by a congenital defect in electron transfer flavoprotein (ETF) or ETF dehydrogenase (ETFDH). Flavin adenine dinucleotide synthase (FADS) deficiency caused by mutations in FLAD1 was recently reported as a novel riboflavin metabolism disorder resembling MADD. Here, we describe a Japanese boy with FADS deficiency due to a novel mutation (p.R249*) in FLAD1. In the asymptomatic male infant born at full term, newborn screening showed positive results with elevated C5 and C14:1 acylcarnitine levels and an increased C14:1/C2 ratio. Biochemical studies were unremarkable except for lactic acidosis (pH 7.197, lactate 61 mg/dL). A diagnosis of MADD was suspected because of mild abnormalities of the acylcarnitine profile and apparent abnormalities of urinary organic acids, although mutations in the ETFA , ETFB , ETFDH , and riboflavin transporter genes (SLC52A1 , SLC52A2 , and SLC52A3) were not detected. Administration of riboflavin and L-carnitine was initiated at one month of age based on the diagnosis of "biochemical MADD" despite a lack of symptoms. Nevertheless, the acylcarnitine profile was not normalized. Symptoms resembling bulbar palsy, such as vocal cord paralysis and dyspnea with stridor, were present from 3 months of age. At 4 months of age, he became bedridden because of hypoxic-ischemic encephalopathy due to fulminant respiratory failure with aspiration pneumonia. At 2 years and 5 months of age, a homozygous c.745C > T (p.R249*) mutation in the FLAD1 gene was identified, confirming the diagnosis of FADS deficiency. His severe clinical course may be caused by this nonsense mutation associated with poor responsiveness to riboflavin. Persistent lactic acidosis and neuropathy, such as bulbar palsy, may be important for diagnosing FADS deficiency. Although the biochemical findings in FADS deficiency are similar to those in MADD, their clinical symptoms and severity may not be identical. [ABSTRACT FROM AUTHOR]

Introduction: In this study we investigated the prognostic significance of cough peak flow (CPF) decline rate in patients with amyotrophic lateral sclerosis (ALS).Methods: Thirty-four patients with ALS participated in our investigation. We examined CPF, forced vital capacity (FVC), body mass index, and the revised ALS Functional Rating Scale (ALSFRS-R), and followed patients to death, tracheostomy, or non-invasive ventilator dependency. We analyzed the relationship between the rate of decline of each parameter and survival prognosis.Results: The CPF decline rate significantly correlated with the decline rates of the ALSFRS-R bulbar score (P < 0.0001) and FVC (P < 0.0001). Patients with a CPF decline rate ≥25% had shorter overall survival (P < 0.0001). Cox model multivariate analyses showed that the CPF decline rate was an independent prognostic factor for survival (P = 0.021).Discussion: The CPF decline rate reflects the progression of bulbar and respiratory dysfunction and predicts survival.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that mainly affects motor neurons in the brain and spinal cord. With the advent of aging societies, the proportion of elderly patients with ALS is expected to increase. We retrospectively compared the clinical characteristics at the initial examination of patients with onset of ALS at age 74 years or younger (early onset) and those aged 75 years or older at onset (late-onset) at a single regional ALS diagnostic center in Japan. The phenotype of late-onset ALS differed between males and females, with late-onset females having more bulbar-onset ALS and significantly lower body mass index, late-onset males having more frequent bulbar and respiratory symptoms at the initial examination, and significantly lower forced vital capacity at the initial examination in both groups compared to early onset patients. For late-onset patients, maintenance of skeletal muscle mass by early intervention for bulbar and respiratory symptoms may be useful for prolonging survival; however, a prospective analysis is warranted. • In a super-aging society, it is important to establish how to manage elderly amyotrophic lateral sclerosis (ALS) patients. • Late-onset females had more bulbar-onset ALS and significantly lower body mass index. • Late-onset males had more frequent bulbar and respiratory symptoms at the initial examination. • Both groups had a significantly lower forced vital capacity at the initial examination than those with early onset. • Maintenance of skeletal muscle mass by early intervention for bulbar and respiratory symptoms may be useful for prolonging survival.

In this review, we summarized three cases of myasthenia gravis (MG) with taste disorder and describe their clinical features in detail. Three MG patients presented with significant bulbar palsy symptoms, high AChR-Ab titers, and negative MuSK-Ab, were diagnosed with thymoma. Furthermore, we observed that dysgeusia could manifest earlier than the occurrence of typical MG symptoms, even predict a MG relapse or a myasthenic crisis in the course of MG. We believe that dysgeusia is a non-motor symptom of MG, which especially exists in MG patients with thymoma and serious bulbar palsy. Therefore, being alert to this symptom may facilitate the early diagnosis of MG and judge the progress of the disease.

Objective To analyze the difference of clinical efficacy of bulbar palsy and pseudobulbar palsy in swallowing rehabilitation and briefly clarified the reasons for the different sensitivity of two types of patients to swallowing rehabilitation.Methods Seventy cases of cerebral palsy from the Department of Rehabilitation Medicine,Huashan Hospital,Fudan University during Jan.,2015 and Oct.,2016 were recruited in this study,including 47 cases in pseudobulbar palsy group and 23 cases in bulbar palsy group.There was no statistical difference in age and course of disease in the two groups.All the patients were given comprehensive swallowing rehabilitation with the same mode and time of intervention for 4 weeks.Watian drinking water test,standardized swallowing assessment (SSA) and video fluoroscopic swallowing study (VFSS) were adopted to evaluated curative effect difference of bulbar palsy and pseudobulbar palsy before and after treatment.Single factor ANOVA test and the rank sum test was used for measurement data.Results After 4 weeks of rehabilitation treatment,the improvement degree of dysphagia induced by pseudobulbar palsy was better than the bulbar paralysis through the comprehensive swallowing training.Conclusions The efficacy of swallowing rehabilitation therapy for pseudobulbar palsy was better than that of bulbar palsy.

Abstract Subacute neuroregression in association with raised neopterin and overexpression of interferon stimulated genes (ISGs) could indicate a type 1 interferonopathy. Here we describe a novel immunotherapy-responsive, clinico-immunological and imaging phenotype with evidence of innate immune activation. Three children (patient 1: 22-month-old boy; patient 2: 5-year-old girl; patient 3: 4-year-old girl) presented with asymmetric bilateral mixed dystonia and spasticity, regression in language (expressive more than receptive) and bulbar symptoms with no evidence of seizures. Symptoms evolved over several weeks to months. Brain MRI changes mimicked cerebral atrophy, initially asymmetric. CSF revealed raised neopterins. Blood RNA assay showed abnormal overexpression of ISGs and transient raised alanine aminotransferase (ALT). Importantly, all three children were treated with intravenous methylprednisolone and immunoglobulin with significant and sustained improvement in their motor and language function, and normalisation of imaging. Immune-mediated encephalitis can masquerade as subacute neuroregression. [ABSTRACT FROM AUTHOR]

Leigh syndrome (LS) is a heterogeneous familial or sporadic neurodegenerative disorder. It is typically seen in infancy or childhood, although rare cases of adult onset have been described. The authors describe a 37-year-old woman who presented with protracted gastrointestinal symptoms followed by acute brain stem syndrome with severe metabolic acidosis and who subsequently showed dramatic clinical and neuroradiological improvement.

A 22-year-old male student with no past medical illness, presented with acute onset dysarthria, binocular diplopia, and dysphagia over 10 hours. On examination, he had tachycardia, hypertension, generalized hyper-reflexia, and bilateral pupil sparing oculomotor, troclear, abducens, trigeminal, facial, glossopharyngeal, and vagus nerve palsy. Rest examination was unremarkable. Facial nerve conduction study (NCS) showed decreased amplitude bilaterally and neurogenic pattern on electromyography. Limb NCS, repetitive nerve stimulation, neostigmine test, brain magnetic resonance imaging, cerebrospinal fluid, and biochemical tests were normal. Only positive tests were low thyroid-stimulating hormone (TSH) (

Medical histories and results of examinations of 165 patients with obstructive sleep apnea syndrome were analyzed. The role of sleep deprivation, innervation of the pharynx and rapid weight gain in different age groups in the genesis of the syndrome was demonstrated. The details of 165 case histories of the patients with obstructive sleep apnea syndrome and results of their cardiorespiratory examinations are analyzed. Role of chronic sleep deprivation, pharyngeal innervation disturbances and fast body mass growth in syndrome genesis in different age groups is discussed.

Acoustic neuroma resection is an example of a neurosurgical procedure where the brainstem and multiple cranial nerves are at risk for injury. Electrode placement for monitoring of the glossopharyngeal and hypoglossal nerves during acoustic neuroma resection can be challenging. The purpose of this report is to illustrate the use of a device for intra-oral electrode placement for intraoperative monitoring of the glossopharyngeal and hypoglossal nerves. A 60-year-old male presented for acoustic neuroma resection. Under general anesthesia, a Crowe-Davis retractor was used to open the mouth, providing access to the posterior pharynx. For glossopharyngeal monitoring, two bent subdermal needle electrodes were inserted just lateral to the uvula. Two additional electrodes were inserted on the lateral tongue to monitor the hypoglossal nerve. Cranial nerves monitoring was conducted utilizing both free running and triggered electromyography of the trigeminal and facial nerves in addition to the lower cranial nerves. The tumor was resected successfully. Monitoring of the cranial nerves (including the glossopharyngeal and hypoglossal nerves) revealed no concerning responses. The Crowe-Davis retractor and the technique described allowed insertion of electrodes for neural monitoring, contributing to neural preservation. [ABSTRACT FROM AUTHOR]

The aim of the study is to investigate acoustic reflex testing in amyotrophic lateral sclerosis patients. Amplitude, latency, and rise time of stapedial reflex were recorded for 500 and 1000 Hz contralateral stimulus. Statistical analysis was performed by the Wilcoxon test and the level of significance was set at 5 %. Fifty-one amyotrophic lateral sclerosis patients and ten sex- and age-matched control subjects were studied. Patients were further divided in two groups: amyotrophic lateral sclerosis-bulbar (38 cases, with bulbar signs at evaluation) and amyotrophic lateral sclerosis-spinal (13 cases, without bulbar signs at evaluation). Stapedial reflex was present in all patients. There was a statistically significant difference in the mean amplitude, latency, and rise time between the amyotrophic lateral sclerosis patients as compared with the controls. Amplitude was lower in both the amyotrophic lateral sclerosis-bulbar and the amyotrophic lateral sclerosis-spinal patients than in the controls ( p < 0.05) and rise time was longer in both patient groups compared with the controls ( p < 0.05). These results confirm the presence of abnormal acoustic reflex patterns in amyotrophic lateral sclerosis cases with bulbar signs and, moreover, suggesting a possible subclinical involvement of the stapedial motor neuron even in amyotrophic lateral sclerosis-spinal patients. Amplitude and rise time seem to be good sensitive parameters for investigating subclinical bulbar involvement. [ABSTRACT FROM AUTHOR]

Background: Transient bulbar palsy without involvement of the facial or extraocular muscles is a rare presentation. It is considered a form of cranial polyneuropathy, a variant of Guillain-Barré syndrome that is related to the autoimmune mechanisms induced by preceding infections or vaccinations. However, drug-induced cranial polyneuropathy has not previously been reported. We describe a boy with isolated bulbar palsy and positive serum antiganglioside antibodies during aripiprazole treatment.Patient Description: This 12-year-old boy was admitted with a seven-day history of dysarthria, tongue discomfort, and tinnitus. Three weeks before symptom onset, aripiprazole was added to the patient's medications for attention-deficit hyperactivity disorder. On examination, he showed curtaining of the pharyngeal wall, tongue fasciculation and deviation, and a weak gag reflex. Cranial magnetic resonance imaging suggested lower cranial nerve involvement. Serum anti-GM1 IgG and anti-GD1b IgG antibodies were positive. After stopping aripiprazole, his bulbar symptoms improved. However, on readministration of aripiprazole seven weeks later, dysarthria recurred and again resolved after stopping the drug.Conclusion: We describe the first patient with anti-GM1 IgG and anti-GD1b IgG antibodies-associated transient cranial polyneuropathy presenting as isolated bulbar palsy. These findings could be an adverse effect of aripiprazole treatment. [ABSTRACT FROM AUTHOR]

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an adult-onset inherited small vessel disease of the brain caused by NOTCH3 mutations. Clinical characteristics of CADASIL include recurrent infarctions, migraine with aura, mood disturbances and cognitive impairment. We report a 35 year-old migraine-free patient with unusual presentation with acute simultaneous multiple subcortical infarctions causing progressive bulbar palsy as the initial manifestation. Hepresented with slurred speech progressing to anarthria and bilateral palsy of lower motor cranial nerves within 24 hour. Initial acute subcortical infarcts enlarged and new infarcts developed in bilateral hemispheres. There was diffuse leukoencephalopathy involving temporal horns and the patient had positive familiy history of migraine and young stroke. CADASIL was diagnosed genetically when NOTCH3 mutationwas shown. The patient improved after treatment with liquid hydration and antiplatelet agent. We experienced with the patient that CADASIL may present with unusual progressive manifestations and bilateral simultaneous infarctions. Irrespective of clinical presentation, patients with leukoencephalopathy and positive familiy history should be tested for NOTCH3 mutation. [ABSTRACT FROM AUTHOR]
