Brain magnetic resonance imaging (MRI) is a key tool for diagnosing neurodegenerative diseases such as Alzheimer’s disease (AD). However, MRI analysis by visual interpretation and reading can be time-consuming and requires specialized expertise. Brain MRI-based artificial intelligence (AI) software has been developed to aid clinicians in diagnosing and managing neurodegenerative disorders, including AD. This study demonstrates the clinical application of the AI software for volumetric analysis of brain MRI scans in patients within the AD spectrum. In the current case series, four patients with memory impairment visited the memory clinic of Yeouido St. Mary’s Hospital. They underwent a series of assessments, including automated analysis of AI-based software for brain MRI volumetric measurements. The information provided by the software was highly accurate, consistent, and was especially valuable for the early diagnosis and monitoring of disease progression. The results imply that this technology potentially aids in the early detection and management of AD, making it a valuable tool for clinicians in the diagnosis of neurodegenerative diseases.

Pulmonary tumors exhibiting neuroendocrine differentiation are classified as typical carcinoid, atypical carcinoid, and small cell lung carcinoma(SCLC). Travis et al. proposed a fourth category of large cell neuroendocrine carcinoma, which is characterized by light microscopic neuroendocrine appearance, cells of large size, polygonal shape, low nuclear cytoplasmic ratio, coarse nuclear chromatin, with prominent nucleoli high mitotic rate and frequent necrosis; and neuroendocrine features by immunohistochemistry or electron microscopy. High grade neuroendocrine carcinoma (LCAC-NE) revealed aggressive clinical course. We report two cases of neuroendocrine tumors of the lung characterized by a trabecular pattern of large pleomorphic cells with frequent mitoses and wide necrosis. The frequent metastatic sites of atypical carcinoid were liver, bone and brain. One of our case is presented, at first, as an ovarian mass, which shows multifocal rosettes and revealed metastasis from lung. Both cases expressed neuroendocrine differentiation by light microscopy and immunohistochemistry. However clinical neuroendocrine symptom were not present.

Historically, gastrointestinal stroma tumors (GIST) have been considered as smooth muscle tumors, but the controversy over this histogenesis is provoked due to various results with utilizing immunohistochemical methods. In andeffort to further clarify the histogenesis of GIST, we performed the immunohistochemical study, as well as histopathologic reexamination, of 24 cases, all diagnosed as smooth muscle tumors of gastrointestinal tract, from Seoul Paik Hospital and Ewha University Hospital between 1980 and 1989, and the main results were as follows; 1) In the histopathologic features by light microscopic study, 11 benign and 13 malignant lesions (including one high grade malignancy and 12 low-grade malignant lesions) were disclosed. 2) In the immunohistochemical study, all tumors showed Vimentin positivity (100%), but no tumor showed S-100 protein positivity (0%), and 7 cases (29.1%) showed Desmin positivity. Positive reaction for Desmin made it possible to suggest that the histogenesis of GIST be in smooth muscle, and neurogenic origin would be excluded by all negativity for S-100 protein. In summary, we would like to conclude that GIST would be smooth muscle tumors on account of their morphological characteristics and their intramural location, but most of them appear poorly differentiated by immunohistochemical method.

PURPOSE: To evaluate the specific findings of angiography for various causes of gastrointestinal bleeding. MATERIALS AND METHODS: We retrospectively analyzed 35 patients of gastrointestinal bleeding detected by angiography, between April 1987 and July 1993. There were 28 men and 7 women, 19 to 83 years old (mean, 47 years). Of these 35 cases of gastrointestinal bleedings, there were 12 gastric bleedings, 4 duodenal bleedings, 9 small intestinal bleeings, 6 ileocecal bleedings, and 4 large intestinal bleedings. RESULTS: Of 35 cases, we could diagnose the specific cause of bleeing in 13 patients (37%) by angiography. Of these 13 cases, there were 4 cases of gastric ulcers showing contrast pooling in ulcer crater, 5 cases of vascular malformations showing anomalous vascular mass with early dilated venous drainage, 2 cases of direct invasion of hepatocellular carcinoma showing invasion of hypervascular mass into small bowel, one case of pseudoaneurysm at gastroduodenal artery in a patient of acute pancreatitis, and one case of small intestinal lymphoma showing contrast pooling in a irregular dilated small intestinal lumen. CONCLUSION: in gastrointestinal bleeding, angiography is useful not only in detecting the bleeding site, but also for evaluating the specific causes such as gastric ulcers or vascular malformations.

PURPOSE: The purpose of this study was to develop an interpersonal relationship harmony program and to investigate the effect of interpersonal relationship harmony program on interpersonal relations, conflict resolution methods, interpersonal anxiety, salivary cortisol level for nursing students. METHODS: The 8-week interpersonal relationship harmony program was developed based on interpersonal relationship harmony theory. The effectiveness of the program was evaluated using a quasi-experimental design. The participants were 58 third-year nursing students, 29 in the experimental group and 29 in the control group. Data were collected from July 5, 2014 to August 25, 2014 and analyzed through t-test. RESULTS: The experimental group showed significantly higher post-test scores in interpersonal relationship harmony, interpersonal relationship ability, active conflict mitigation and significantly lower post-test scores in active conflict intensification, interpersonal relationship anxiety than those of the control group. CONCLUSION: The interpersonal relationship harmony program improved nursing students' interpersonal skills and conflict resolution methods and reduced interpersonal relationship anxiety through an integrated approach that covered the cognitive, emotional, behavioral, and physical aspects of harmony.

A case of primary gastric carcinoma with patterns resembling those of hepatocellular carcinoma(HCC) is reproted. This patient who represented high serum alpha-fetoprotein(AFP) underwent a subtotal gastrectomy for stomach cancer and lobectomy of liver metastasis. The hepatoid component of the tumor was characterized by solid nests of large polygonal cells arranged in cords and trabeculae, with central nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm; single-nuclear giant cells were frequently noted. These tumor cells of stomach stained positive immunohistochemically for AFP, ACT(alpha-1-antitrypsin), AACT(alpha-1-antichy-motrypsin). Thus, this hepatoid gastric adenocarcinoma tumor cells demonstrated both morphologic and immunohistochemical features of partial differentiation to the HCC. Careful histologic examination in conjunction with the immunohistochemical demonstration of AFP can provide a useful contribution to the diagnosis of this rare histological type of gastric carcinoma And the presence of metastatic hepatoid adenocarcinoma from the stomach should be considered in a patient with hepatic tumor mimicking HCC. Because of frequent venous and lymphatic invasion, as well as liver metastasis, prognosis appears to be poor. The authors reviewed 45 cases of hepatoid adenocarcinoma of stomach reported in the literature, also.

BACKGROUND: A retrospective study was performed to evaluate postoperative mortality within 30 days following surgery. METHODS: The records of 31,806 patients who received operation under general anesthesia were reviewed. RESULTS: 1) Postoperative deaths were 184 cases, the ratio of which was comprising 0.57% of all surgical operative cases. 2) The highest ratio of the mortality in age group was 51~60 years group which was 24.5%, and in physical status it was ASA class III which was 36.4%. The highest ratio to the mortality rate in postoperative days was 8~30 days which was 45.1%. 3) The most common causes of death was low cardiac output due to heart failure on operating theater, and hypovolemic shock within postoperative 2 days, and intracranial problem within postoperative 7 days, and pulmonary complication within postoperative 30 days. CONCLUSION: We conclude that fatality rate could be decreased by intensive and multidisciplinary care for postoperaive complications as respiratory and renal failure.

Despite on-going efforts to control malaria, the rate of malaria has not decreased throughout the world. It was believed that endemic malaria had been eradicated in Korea since the end of the 1970s, however it reemerged from 1993 and has been increasing ever since. Besides endemic malaria, imported malaria is also increasing in Korea as the number of overseas travellers and foreign workers increases. We discovered malaria in a two-year-old child who visited Sierra Leone with his missionary father. The patient contracted malaria despite chemo-prophylaxis with chloroquine and was diagnosed as falciparum malaria by blood smear examination and IFAT. He successfully recovered after administraion of quinine and clindamycin without complication. However, the malaria did not respond quickly to chloroqine and Fansidar but a drug resistence test was not performed.
