Peptic ulcer disease is a gastrointestinal disorder caused by Helicobacter pylori infection and the use of nonsteroid anti-inflammatory drugs. While many studies have been conducted to find the risk factors of peptic ulcers, there are no studies on the suggestion of peptic ulcer prediction models for Koreans. Therefore, the purpose of this study is to implement peptic ulcer prediction model using machine learning based on demographic information, obesity information, blood information, and nutritional information for middle-aged and elderly people. For model building, wrapper-based variable selection method and naive Bayes algorithm were used. The classification accuracy of the female prediction model was the area under the receiver operating characteristics curve (AUC) of 0.712, and males showed an AUC of 0.674, which is lower than that of females. These results can be used for prediction and prevention of peptic ulcers in the middle and elderly people.

Objectives : Stress induces alteration of gastrointestinal function in which interleukin (IL) and hypothalamo-pituitary-axis are involved. Depression again is associated with functional gastrointestinal disorders (FGID) and interleukins. The author attempted to look into the role of interleukins in the FGID also the association of depression and stress in this context. Methods : Entered were 20 patients with FGID, diagnosed by Rome IT criteria and 20 healthy controls. Depression was measured by Hamilton Rating Scale for Depression (HAM-D), and stress of the last one year by Schedule of Recent Experience (SRE). Serum levels of IL-$1\beta$, IL-2, IL-6 were measured by Enzyme-linked Immunosorbent Assay and serum cortisol by Fluorescence Polarization Immunoassay. The results were as follows : Results: 1) Serum levels of IL-$1\beta$, IL-2 were significantly lower in the patients with FGID than those in the controls, but level of IL-6 did not differ between two groups. 2) The patient group showed significantly higher level of serum cortisol as well as higher degrees of depression and stress. 3) Positive correlation was noted between depression and serum cortisol, and between depression and IL-2. A trend of negative correlation was seen between depression IL-$1\beta$. Positive correlation was noted between SRE and IL-6 and IL-6 and serum cortisol. Conclusions : It was concluded that FGID might be related to depression and stress. Changes of the interleukins might be involved with elevated cortisol level.

A case of a 38 year-old woman with histrionic personality who had chronic epigastric pain, dyspepsia and alternating bowel habit for more than 10 years was presented in detail on its course of two times of admission and follow-up. The diagnosis was thought as psychophy-siological disorder or gastrointestinal motility disorder of undefined etiology rather than hypo-chondriasis or Briquet's syndrome. She was characterized by sustained illness behavior and combined several physical illnesses. i.e. tuberculosis. anemia and hepatic stone. These physical diseases led to a blurring of psychological and physical boundaries regarding symptom formation. The points on consultation from medical part to psychiatric department were discussed and the supposed causal mechanisms in non-organic functional gastrointestinal disturbances were also reviewed. Physical and psychological modalities for the treatment and the abnormal illness behavior were mainly emphasized in this case.
