Research progress of precise differential diagnosis of psychogenic non-epilepsy seizures and epilepsy / 中华神经科杂志

Psychogenic non-epilepsy seizures (PNES) are defined as paroxysms with clinical symptoms similar to epilepsy without epileptiform discharges. It is often misdiagnosed as epilepsy. Misdiagnosis not only delays the time for patients with PNES to get correct diagnoses and treatments, but also may increase the risk of adverse effects from improper use of antiseizure medications. The diagnostic method of PNES is video electroencephalogram monitoring, but there is no consensus on the optimal duration of monitoring. At the same time, the use of diverse physiological signals, brain imaging, laboratory examination, and the application of machine learning provide new perceptions for the precise identification of PNES and epilepsy. This article reviewed the progress of precise differential diagnosis between PNES and epilepsy.

Clinical Efficacy Analysis of Herbal Ion Application and Penetration Therapy for Prevention and Treatment of Recurrent Respiratory Tract Infection in Children / 广州中医药大学学报

Objective To compare the clinical efficacy of herbal ion application and penetration therapy applied in the dog days, or in both of the dog days and coldest days for the treatment of recurrent respiratory tract infection (RRTI) in children. Methods This intervention was designed as a multi-center, randomized, single-blind, repeated-measurement design. A total of 240 RRTI children were randomly divided into Sanfu group (N=120, herbal ion application and penetration therapy applied in the dog days) and Fujiu group (N=120, herbal ion application and penetration therapy applied in both of the dog days and coldest days). Each group was treated for one year and then was followed up for one year. Before and after the treatment, we observed the frequency of respiratory tract infection, the period of onset, signs and symptoms of traditional Chinese medicine (TCM), and detected the salivary secretory immunoglobulin A (sIgA) at different time points. Results (1) The therapeutic effect of Fujiu group was better than that of Sanfu group, and the difference was significant (P<0.05). (2) The frequency of respiratory tract infection was reduced, the period of onset was shortened, and TCM signs and symptoms were improved in both groups, and the effect of Fujiu group was superior to that of Sanfu group (P<0.05). (3) Salivary sIgA showed a continuous upward trend in Fujiu group while a mild downward trend in Sanfu group at different time points (P<0.05). Conclusion Herbal ion application and penetration therapy applied in both of the dog days and coldest days shows better effect for the treatment of children RRTI than that applied only in the dog days.
