We performed successful RFCA in a 5-year-old child for supraventricular tachyarrhythmia and Wolff-Parkinson-White Syndrome. Acute circumflex artery (CxA) occlusion occurred due to RFCA. After percutaneous balloon angioplasty was performed into the CXA, the patient was treated with systemic steroid to resolve myocardial edema. To the best of our knowledge, systemic steroid was the first time used for acute coronary artery injury related myocardial ischemia. This article is protected by copyright.

It was proposed that TCI would bring more clinical benefit because of the precision of the approach and the ability to link TCI to principles of pharmacokinetics and pharmacodynamics to predict the dose required by an individual (1). We examine the theory and clinical trial evidence supporting the benefits of TCI over TDM and conclude that in the digital age TDM should be abandoned and replaced by TCI.Therapeutic strategies for severe hand, foot, and mouth disease (HFMD) are currently either inconsequent or deficient in evidence. We retrospectively surveyed HFMD outbreaks in Xiangyang from June 2008 to December 2013. HFMD is staged form I to V according to clinical severity and the case with central nervous system involvement is defined as a severe one. We analyzed risk factors for fatality of severe cases and compared the efficiency and outcome of some therapies by binary logistic regression. The overall HFMD cases included 637 (1.26%) severe cases, 38 fatalities (0.75‰). Analysis indicates that age ( 0.05). Precise recognition of the severe HFMD cases in early stage IV and prompt IVIG and mechanical ventilation application may decrease mortality. Mechanical ventilation training programs and dispatchin
