PURPOSE The aim of this study is to investigate the changing prevalence rate of Helicobacter pylori infection in children, of different age groups, with recurrent abdominal pain over a 10-year period. METHODS Children with recurrent abdominal pain who visited the pediatric outpatient clinic at university hospital were screened for H. pylori. Children were(More)
BACKGROUND The purpose was to compare the efficacy between tenofovir disoproxil fumarate (TDF) and lamivudine (LMV) in children with nucleos(t)ide-naive chronic hepatitis B (CHB) infection. Patients with CHB were treated with TDF in the immune-reactive phase and compared with a historical control group of patients treated with LMV before the TDF era. (More)
Intussusception is rarely observed in adults. Adult cases account for only 5% of all cases of intussusceptions and almost 1%-5% of bowel obstruction cases. The etiology, presentation and management of intussusception in adults are different from those in children. The clinical presentation in adults often includes nonspecific signs and symptoms, thereby(More)
PURPOSE The prevalence of reflux esophagitis (RE) has increased recently in Korea. Little is known concerning the prevalence and characteristics of RE in pediatric patients. This study investigated the prevalence and influence of risk factors in endoscopically proven RE in Korea in pediatric patients over a period of 14 years. METHODS A retrospective(More)
BACKGROUND TNF-α regulates immune cells and acts as an endogenous pyrogen. Reverse transcription polymerase chain reaction (RT-PCR) is one of the most commonly used methods for gene expression analysis. Among the alternatives to PCR, loop-mediated isothermal amplification (LAMP) shows good potential in terms of specificity and sensitivity. OBJECTIVE(More)
Descending necrotizing mediastinitis (DNM) is a rare form of mediastinal infection. Most cases are associated with esophageal rupture. DNM after a trigger point injection in the upper trapezius has not been described previously. We present a case of DNM after a trigger point injection in the upper trapezius. A 70-year-old man visited the emergency(More)
The surface during the etching of Si in a Cl2 inductively-coupled plasma ~ICP! was analyzed by laser desorption ~LD!, followed by detection of the desorbed species by monitoring the transient changes by plasma-induced emission ~PIE!. Optical emission from Si, SiCl, SiCl2, and possibly other species was detected in situ using this LD-PIE method as a function(More)
The etching of silicon by a chlorine inductively coupled plasma ~ICP! was studied using laser desorption laser-induced fluorescence ~LD-LIF! analysis to determine the surface coverage of chlorine during steady-state etching. Laser interferometry was used to measure etch rates, and optical emission actinometry and Langmuir probe analysis were used to(More)
Laser desorption laser-induced fluorescence ~LD-LIF! detection of GeCl was used to determine in situ the surface coverage of chlorine during the etching of germanium by Cl2 in an inductively coupled plasma ~ICP! reactor. The ICP operated in the dim mode for radio frequency ~rf! power &350 W and in the bright mode for higher powers. The etch rate was 3.5(More)
