Background Ingestion of button batteries occurs in about ten persons per one million persons each year, with most of them children, and one in every 1000 battery ingestions leads to serious injuries. This study aimed to describe the clinical features and outcome of ingestion or inhalation of button batteries in children spanning a decade from January, 2006 to December, 2016 at a tertiary care hospital. Methods We reviewed the clinical records of children who sought treatment for inhaled or ingested button batteries at our hospital during the study period. Data on gender, age, time from ingestion to treatment, site of impaction, imaging findings, and outcomes were retrieved and analyzed. Results We identified 116 pediatric cases of ingestion or inhalation of button batteries. Their mean age was 26 months. The time from ingestion or inhalation of button batteries to treatment was 0.5 hours to 2 weeks. Ninety-seven (83.6%) button batteries were located in the nasal cavity, 13 (11.2%) in the gastrointestinal (GI) tract including 6 in the esophagus, and 7 in the stomach and lower GI tract, and 6 (5.2%) in the auditory tract. Twenty-one (21.6%) children with nasal button batteries had preoperative septal perforations and one (1.0%) had postoperative septal perforation. One child with esophageal button battery developed esophageal stricture and one died of sudden cardiac arrest perioperatively. One child had auditory dam-ages in the right tympanic membrane and ossicles. Conclusions Inhalation or ingestion may occur in the nasal cavities, the esophagus and GI tract and the auditory tract. Prompt diagnosis and treatment are required for a satisfactory outcome and ingested or inhaled button batteries require different treatment protocols.

作者： Bo Qin Huaicheng Yan kai rao Penghui Yang Key Laboratory of Smart Manufacturing in Energy Chemical Process of Ministry of Education East China University of Science and Technology Hubei Key Laboratory for High-efficiency Utilization of Solar Energy and Operation Control of Energy Storage System Hubei University of Technology

This paper focuses on the tracking problem of a perturbed wheeled mobile robot(WMR). Taking both the kinematic model and dynamic model into account, a transformed model is proposed based on the heading position. By extracting deep-root information from the lumped disturbance, the influence of the lumped disturbance can be estimated and eliminated by a simple adaptive compensation term. concurrent learning(CL) is introduced to the adaptive law to relax the persistent excitation(PE)condition. A Lyapunov-based method is used to ensure globally uniformly ultimately bounded(GUUB) stable tracking. The proposed control strategy is proven effective by a numerical simulation.
