Enterovirus 71 (EV71) is a common etiological agent of hand, foot, and mouth disease and fatal neurological diseases in children. The neuropathogenicity of severe EV71 infection has been documented, but studies comparing mouse models of severe and mild EV71 infection are lacking. The aim of the study was to investigate the neurovirulence of EV71 strains and the differences in serum cytokine and chemokine levels in mouse models of severe and mild EV71 infection. Nine EV71 isolates belonging to the C4 subgenogroup (proposed as genotype D) displayed infectivity in human neuroblastoma SK-N-SH cells; moreover, ultrastructural observation confirmed viral particle replication...

BACKGROUND AND OBJECTIVE: Microfocused ultrasound (MFUS) technology has been utilized since 2009 for improvement in mild to moderate skin and soft tissue laxity of the face and neck. Few complications have been previously reported, the majority of which include mild and transient erythema, edema, ecchymosis, and nerve paralysis. Rare yet serious potential complications of MFUS for noninvasive skin tightening of the face and neck are, however, possible. METHODS & MATERIALS: Retrospective multicenter case series of five patients from the authors' practice who developed serious adverse events directly related to MFUS with a commercially available device (Ultherapy; Merz North America, Inc...

BACKGROUND: The rates of thoracoscopic esophagectomy performed in the prone and left lateral decubitus positions are similar in Japan. We retrospectively reviewed short- and long-term outcomes of thoracoscopic esophagectomy for esophageal cancer performed in the left lateral decubitus position. METHODS: Between 1996 and 2015, 654 patients with esophageal cancer underwent thoracoscopic esophagectomy in the left lateral decubitus position. Patients were divided into early (1996-2008) and late groups (2009-2015, with standardization of the procedure and formalized training), and their clinical outcomes reviewed...

BACKGROUND: To reanimate the mimetic muscles, crossface nerve graft (CFNG) is an effective surgical option. However, muscle atrophy after facial paralysis may influence the surgical result. We analyzed the relationship between surgical result and preoperative paralysis duration. METHODS: We performed CFNG on 15 patients. The sural nerve was transferred between the affected and nonaffected sides of the zygomatic branch. Eyelid function and eyelid lid were evaluated using the modified House-Brackmann scale...

Periodic paralyses (PP) are rare neuromuscular disorders caused by mutations in skeletal muscle sodium, calcium, and potassium channel genes. PP include hypokalemic paralysis, hyperkalemic paralysis, and Andersen-Tawil Syndrome. Common features of PP include autosomal dominant inheritance, onset typically in the first or second decades, episodic attacks of flaccid weakness, which are often triggered by diet or rest after exercise. Diagnosis is based on the characteristic clinic presentation then confirmed by genetic testing...

INTRODUCTION: After stroke, hemiplegia, dysphasia and facial paralysis can manifest during the convalescent period. Currently, no Chinese patent medicine (CPM) is previously reported to cure each of these symptoms primarily, and thus, there are no relevant instructions for the use of CPM. This study presents a new approach based on comparative effectiveness research to distinguish the curative effects of three CPMs that are often used in stroke convalescence to determine the ideal medicine for the treatment of each symptom...

BACKGROUND: All reports of increases in severe respiratory disease associated with human enterovirus D68 (EV-D68) are from hospital settings. However, there are few reports describing clinical characteristics in less severely affected populations. METHODS: We conducted a retrospective observational study from January 2010 to December 2015 in Yamagata, Japan. Using regional passive surveillance, 5794 respiratory specimens were collected from children who initially presented to an outpatient clinic with acute respiratory symptoms...

Type 1 hypokalemic periodic paralysis (HypoPP1) is a poorly understood genetic neuromuscular disease characterized by episodic attacks of paralysis associated with low blood K(+) The vast majority of HypoPP1 mutations involve the replacement of an arginine by a neutral residue in one of the S4 segments of the α1 subunit of the skeletal muscle voltage-gated Ca(2+) channel, which is thought to generate a pathogenic gating pore current. The V876E HypoPP1 mutation has the peculiarity of being located in the S3 segment of domain III, rather than an S4 segment, raising the question of whether such a mutation induces a gating pore current...

BACKGROUND: Glossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome caused by neurovascular conflict. Compared to trigeminal neuralgia or hemifacial spasm, the incidence of GPN was very low. Until now, little is known about the long-term outcome following microvascular decompression (MVD) process. METHODS: Between 2006 and 2016, 228 idiopathic GPN patients underwent MVD in our department. Those cases were retrospectively reviewed with emphasis on intraoperative findings and long-term postoperative outcomes...

OBJECTIVES: Non-dystrophic myotonia, periodic paralysis and, to a certain extent, myotonic dystrophies are rare hereditary skeletal muscle channelopathies, charactarized by myotonia or episodic muscle weakness. This review highlights the diagnostic challenges and treatment options. RESULTS: Some of these rare skeletal muscle disorders are associated with a broad range of systemic and nonspecific muscle symptoms. Consequently, patients are often referred to the internist before seeing a neurologist...

Tick paralysis has a major impact on pet dog and cat populations in southeastern Australia. It results from envenomation by Ixodes holocyclus and Ixodes cornuatus ticks, the role of Ixodes cornuatus in the epidemiology of this disease in Australia being unclear. The aim of this study was to describe the geographical distribution of tick paralysis cases in southeastern Australia using data from a national disease surveillance system and to compare characteristics of "endemic" cases with those reported outside this endemic zone ("sporadic" cases)...

Arytenoid cartilage dislocation is a rare but curable cause of hoarseness and is commonly related to intubation or laryngeal trauma. We present a case of arytenoid cartilage dislocation without a traumatic event in a man who complained of acute hoarseness. An 82-year-old man visited our emergency department complaining of acute hoarseness. He had no history of general anesthesia or laryngeal trauma and had not caught a cold. He showed no abnormal physical findings including the pharynx. Examination using a laryngoscope revealed that the left vocal fold was fixed in the paramedian position...

The calcium channel, voltage-dependent, L-type, alpha 1S subunit (CACNA1S) gene encodes a skeletal Ca2+ channel which is involved in calcium-dependent processes such as muscle contraction and neurotransmitter release. Mutations in this gene have been accompanied by hypo- and normokalemic periodic paralysis, thyrotoxic periodic paralysis, and susceptibility to malignant hyperthermia. We report the clinical and genetic findings in a patient diagnosed with metabolic myopathy who had episodic attacks of muscle pain and weakness but with no family background of the disease...

The main causes of hypokalemia are usually evident in the clinical history of patients, with previous episodes of vomiting, diarrhea or diuretic use. However, in some patients the cause of hypokalemia can become a challenge. In such cases, two major components of the investigation must be performed: assessment of urinary excretion potassium and the acid-base status. This article presents a case report of a patient with severe persistent hypokalemia, complementary laboratory tests indicated that's it was hypomagnesaemia and hypocalciuria associated with metabolic alkalosis, and increase of thyroid hormones...
