Comparative Study
Barrett's esophagus and severe reflux esophagitis share common pathophysiological characteristics among Chinese in Taiwan.
The pathophysiological data on Barrett's esophagus are scant in Asia, so the purpose of this study was to compare and analyze the pathophysiological characteristics of Barrett's esophagus and reflux esophagitis among Chinese in Taiwan. ⋯ We concluded that Barrett's esophagus had significantly stronger acid reflux, lower LES pressure, and weaker distal esophageal peristalsis compared to mild esophagitis. Barrett's esophagus and severe reflux esophagitis share common pathophysiological characteristics among Chinese in Taiwan.

Case Reports
Zygomycosis presenting as acute myocardial infarction during hematological malignancies.
Here we report two patients with hematological malignancies associated with complications of fatal cardiac zygomycosis. The first case, a 72-year-old man with myelodysplastic syndrome being treated with low-dose cytarabine, died of sudden cardiac arrest. An autopsy revealed disseminated zygomycosis accompanied with occlusion of the coronary artery by fungal thrombi. ⋯ She experienced sudden bradycardia with unstable hemodynamics and died of acute myocardial infarction. Histological examination of a skin biopsy demonstrated zygomycosis. In light of the above, it should be kept in mind that cardiac zygomycosis might occur in hematologically compromised patients presenting with acute myocardial infarction.

We present a 21-year-old woman with an oculogyric crisis following the administration of clebopride. Based on the temporal relationship of the administration of clebopride to the occurrence of the event and the absence of other possible etiologies, clebopride is implicated as the cause of this acute oculogyric crisis, despite the fact that a cause-and-effect relationship cannot be confirmed.

A 62-year-old man developed a fever, fatigue, anorexia and arthralgia. Central hypocorticoidism and central hypothyroidism were observed, and a low serum antidiuretic hormon level without symptoms of diabetes insipidus, as well. Images showed swelling of pituitary stalk, mediastinal and hilar lymphnodes and pancreas, pulmonary infiltrates and retroperitoneal mass. ⋯ These features were similar to those of reported IgG4-related autoimmune disease. However, replacement steroid therapy for hypocorticoidism brought about almost complete recovery except that diabetes insipidus got apparent. This is the first report on the efficacy of only a small dose of steroid, and on features of pituitary stalk involvement and central hypocorcicoidism.

Comparative Study
Natural human interferon beta plus ribavirin combination therapy in Japanese patients infected with hepatitis C virus and a high viral load.
The aim of this pilot study was to determine the safety and efficacy of natural human interferon beta (nIFNbeta) plus ribavirin (RBV) in patients with chronic hepatitis C who did not respond to pegylated interferon alpha (PEG-IFN), with special emphasis on the incidence of mental disorders or refusal for fear of adverse effects. ⋯ nIFNbeta-RBV therapy offers sufficient safety and efficacy for patients with mental disorders, and thus could represent an excellent second-line therapy for subpopulations that are not suitable for PEG-IFN-RBV.
