This analysis was undertaken to compare the clinicopathological features of infants with choledochal cysts to those of older children with these entities and to evaluate the surgical outcomes for both subject groups. The medical records of all children admitted to the Cathay General Hospital with choledochal cysts over a 20-year period were retrospectively(More)
OBJECTIVES Appendicitis is the most common abdominal condition leading to urgent surgery in children. With the goal of identifying signs and symptoms that will allow prompt diagnosis of rupture of the appendix and thus decrease associated morbidities, our aim was to determine factors associated with ruptured appendicitis in children diagnosed with(More)
A high voltage driving circuit having pulse mode is proposed for driving tubular field emission lamp (FEL). The employed main circuit topology, which is a flyback converter operated in discontinuous conduction mode (DCM), will not only provide a low cost negative pulse feature, but also eliminate the arcing phenomenon caused by traditional DC driving so as(More)
An impulsed-power generator, which possesses low cost and simple configuration, operated in discontinuous conduction mode (DCM) for driving a tubular field emission lamp (TFEL) is presented in this paper. The proposed system based on flyback topology can provide impulse power driving to eliminate the arcing phenomenon caused by the traditional DC voltage(More)
This paper presents a battery charger for LiFePO<inf>4</inf> battery pack based on a series-resonant topology. The synchronous rectification technique is incorporated into the proposed system to improve the charging performance. Moreover, the frequency domain analysis and the equivalent circuit of each operation mode are descried and conducted. The(More)
OBJECTIVE To assess the effectiveness of conservative treatment for adhesive small bowel obstruction (ASBO) in children. DESIGN Systematic review of studies involved children with ASBO who received initial conservative/non-operative treatment. SETTING The search was performed in April 2013 using PubMed (see online supplementary file 1), current(More)
In this paper, A MCU-based electronic ballast for electrodeless fluorescent lamp (EFL) is implemented. The used two stage system consists of a power factor corrector and a class D resonant inverter. In addition, an 8-bit microcontroller is employed to act as the control core of the system to achieve digital control feature. Moreover, we not only discuss the(More)
BACKGROUND/PURPOSE The diagnostic and therapeutic benefits of a commercial water-soluble contrast agent (Gastrografin) in pediatric patients with adhesive small-bowel obstruction (ASBO) are controversial. The aim of this study was to assess the therapeutic value of Gastrografin in the management of ASBO in children after unsuccessful conservative treatment.(More)
A MCU-based charger for the LiFeO<sub>4</sub> battery pack is implemented in this paper. The main circuit is a full-bridge phase-shift converter. The user can select the charging strategy and observe the state of charge (SOC) of the battery from the operation interface. Moreover, the proposed charger system communicates with the battery management system(More)
