BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary

OBJECTIVES: Auditory verbal hallucination (AVH) is knoun for its high prevalence and difficulty in evaluation. Authors hypothesized that it may be possible to find useful dimensions of AVH that reflect the clinical status of schizophrenic patients by assessing the multi-dimensional changes and linguistic forms' of AVH during antipsychotic treatment. METHODS: 33 schizophrenic patients with AVH were selected and periodically assessed with the 11 items of hallucinations subscale of 'The Psychotic Symptom Rating Scales (PSYRATS)'. In addition, to assess the linguistic forms observed in the AVH, the evaluations of sentence structure of AVH reported by the patients were conducted. RESULTS: PSYRATS showed the multidimensionality inherent in AVH. The changes in the quantitative dimensions did not correlate well with patients' subjective distress. However, qualitative changes in the cognitive and emotional dimensions showed more favorable correlation with clinical course of the patient. The sentence structures of AVH showed tendency to change from "sentence" to "non-sentence" type with overall improvement during treatment. CONCLUSION: Multi-dimensional approach to AVH can give us more information about the changing patterns of multi-faceted structure of AVH and clinical status of patients than one-dimensional or categorical approach.

Single coronary artery is a rare congenital anomaly occurring in approximately 0.04% of the population. This entity can be diagnosed during life only by coronary angiography. Typical angina does not occur with single coronary artery in the absence of coexisting coronary artery disease or aortic stenosis. Among 874 patients who underwent diagnostic coronary angiography at Asan Medical Center. we have experienced a case of single coronary artery with significant atherosclerotic coronary artery disease which has been managed succesfully coronary angioplasty. We report this case of single coronary artery with a review of literature.

Of several possible configurations of pin fixation of a displaced supracondylar fracture of the humerus in children, the medial and lateral crossed pinning technique has been known to provide the greatest resistance to gross rotational displacement. A new technique with ipsilateral two lateral crossed pins was devised so as to avoid the ulnar nerve injury with good stability for fracture site. During the period from 1992 to 1994, 18 children with displaced supracondylar fracture of the humerus were treated by closed reduction and ipsilateral two lateral crossed pinning. Eighty nine percents of the final results were satisfactory. There were no ulnar nerve injuries and fixation loss in all cases from the treatment. This is a safe, simple and reliable technique for providing the good stability of fracture site as well as avoiding the ulnar nerve injury.

Orientia tsutsugamushi is obligate intracellular bacterium that grows within the cytoplasm of the eukaryotic host cells. Therefore capability of the attachment, entry into the host cell and intracellular survival should be critical process for oriential infection. In this study we investigated the cellular invasion mechanism of Orientia tsutsugamushi and the role of transmembrane heparan sulfate proteoglycan, which binds diverse components at the cellular microenvironment and is implicated as host cell receptors for a variety of microbial pathogens. First of all Orientia tsutsugamushi can invade a wide range of nonprofessional phagocytic cells including fibroblast, epithelial cells a#nd endothelial cells of various host species, including B and T lymphocytes. Thus, it was postulated that the attachment of O. tsutsugamushi requires the recognition of ubiquitous surface structures of many kinds of host cells. Treatments with heparan sulfate and heparin inhibited the infection of Orientia tsutsugamushi in dose-dependent manner for L cell, mouse fibroblast, whereas other glycosaminoglycans such as chondroitin sulfate had no effect. Collectively, these findings provide strong evidence that initial interaction with heparan sulfate proteoglycan is required for the oriential invasion into host cells.

Hypopituitarism is not a common cause of delayed puberty, however it should always be considered, especially if there are such signs as severe dwarfism, dollish face, truncal obesity, small hands and feet, and microgenitalia. Either congenital or acquired, hypopituitarism can be resulted from hypothalamic and hypophyseal lesions. The clinical feature can be diverse depending on age of the patients, rate of progression, degree of hormone deficiency and characteristics of the lesion. The recent high interest in delayed puberty and the improved detection of hypothalamic hypophyseal lesions using combined pituitary fuction stimulation test, brain CT and MRJ, has made the differential diagnosis of hypopituitarism possible as the cause of delayed puberty. MRI has shown hypophyeal hypoplasia accompanied by anterior pituitary hypoplasia and ectopic neurohypophysis in some of the patients with hypopituitasm, and although the anatomical abnormality around the hypophysis in these patients is considered the reason for hypopituitarism, the pathogensis of which has not yet to be known. We, here, report a case of delayed puberty by hypopituitarism due to hypoplasia of anterior pituitary gland, pituitary stalk agenesis and ectopic neurohypophysis with brief review of the litereature.
