Successful Removal of a Screw Nail in the Jejunum Using Double-Balloon Enteroscopy.

The vast majority of foreign bodies (FBs) that enter the stomach pass through the gastrointestinal tract spontaneously. When the FB enters the small bowel-beyond the reach of conventional endoscopy-daily radiographs are needed to ensure its safe passage. However, endoscopic intervention is an appropriate management strategy for a sharp-pointed FB, because sharp FBs have a higher risk of intestinal perforation.

Airway hyperresponsiveness to hypertonic saline as a predictive index of exercise-induced bronchoconstriction.

Background: Changes in airway mucosal osmolarity are an underlying mechanism of bronchoconstrictive responses to exercise and hypertonic saline (HS). The purpose of this study was to examine whether an osmotic challenge test using HS can predict exercise-induced bronchospasm (EIB) in asthma patients.

Methods: Thirty-six young male asthmatic patients underwent bronchial challenge tests based on 4.

[Efficacy of repeated hepatic arterial infusion chemotherapy in advanced hepatocellular carcinoma with portal vein tumor thrombosis].

Background/aims: The aim of this study is to elucidate the efficacy of repeated hepatic arterial infusion chemotherapy (HAIC) and different chemotherapeutic regimens for treating patients having advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT).

Methods: From Jan. 1999 and Dec.

[Reappraisal of HBV genotypes and clinical significance in Koreans using MALDI-TOF mass spectrometry].

Background/aims: Recent studies have shown that the genotype of hepatitis B virus (HBV) may correlate with the disease natural history and treatment outcome. However, several of these studies used low sensitivity assays in a small number of patients, and this has precluded an accurate evaluation of Korean HBV genotypes. We analyzed Korean HBV genotypes in a large population by employing a new technology, restriction fragment mass polymorphism (RFMP) using MALDI-TOF mass spectrometry, in a sensitive and specific manner.

Steroid-induced delirium in a patient with asthma: report of one case.

Systemic steroids are highly effective for patients with moderate-to-severe asthma exacerbations. Steroid-induced psychosis is known to be one of the adverse effects of steroid therapy, although infrequent. However, there is no reliable method of predicting steroid psychosis.
