Neuromyelitis optica spectrum disorder (NMOSD) is a chronic inflammatory disease of the nervous system, which is frequently accompanied by a pathological humoral immune response against aquaporin-4 water channel. The most common feature of the disorder is recurrent episodes of longitudinally extensive transverse myelitis and optic neuritis. Frequent relapse leads to the gradual accumulation of neurological dysfunction. Azathioprine (AZA) is an empirical attack -preventive immunotherapies drug to prevent the relapse of NMOSD, and tocilizumab (TCZ) has been also reported reduce the activity of NMOSD. Therefore, we designed this systematic review and meta-analysis to evaluate the efficacy between TCZ and AZA in the treatment of NMOSD patients. ⋯ The results of this study showed that the treatment of NMOSD patients with AZA and TCZ are associated with decreased number of relapses and disability improvement as well. In addition, compared with AZA, TCZ more significantly reduce ARR.

Dravet syndrome (DS) is a rare and severe myoclonic epilepsy, with onset commonly occurring in infancy. Seizures are triggered by various causes, including fever, bathing, and light stimulus. DS is refractory to drug treatment. Moreover, status epilepticus (SE) can cause serious encephalopathy and epilepsy-related deaths. There are very few reports of general anesthesia in DS patients. Herein, we report our experience with the anesthetic management of a pediatric patient with DS. ⋯ It is essential to pay attention to managing BT and to avoid drugs that induce seizures during anesthesia for patients with DS. Cautious preoperative planning for anesthesia based on evaluation of the patient and rapid postoperative response in collaboration with the attending pediatrician is necessary in case an epileptic seizure occurs.

Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA) is a rare nasopharyngeal malignant tumor that is easy to misdiagnose. Immunohistochemistry plays an indispensable role in distinguishing TL-LGNPPA from other malignancies. However, there is no article to summarize the immunohistochemical characteristics of TL-LGNPPA. Herein, we report a case of TL-LGNPPA and present the immunohistochemical results reported in the Chinese literature. ⋯ The 4th edition of the World Health Organization Classification of Head and Neck Tumors (WHO-HNT) indicates that NPPA with positive expression of cytokeratin 19 (CK19) and TTF-1 and negative expression of TG is called TL-LGNPPA.

Virtual reality (VR) is an interesting and promising way to teach cardiopulmonary resuscitation (CPR) to adult laypersons as its high immersive characteristics could improve the level of skills and acquired knowledge in learning basic life support (BLS). ⋯ VR in BLS training improves manual skills and self-efficacy of adult laypersons and may be a good teaching method in a blended learning CPR training strategy. VR may add another way to divide complex parts of resuscitation training into easier individual skills. However, the conclusion of this review suggests that VR may improve the quality of the chest compressions as compared to instructor-led face-to-face BLS training.
