Idiopathic restrictive cardiomyopathy is characterized by clinical and hemodynamic findings of restrictive cardiomyopathy in the absence of morphologic cause. The differential diagnosis between idiopathic restrictive cardiomyopathy and noncalcified constrictive pericarditis is difficult but the distinction is crucial because of the therapeutic implication. The diagnosis of idiopathic restrictive cardiomyopathy is aided by echocardiography and cardiac catheterization, cardiac magnetic resonance imaging. The patients should be approached systemically to differentiate from noncalcified constritive pericarditis.

The objective of this study was to realize research demands by gathering the research agenda from the Korean Dental Hygienists Association and affiliated groups through a Delphi survey. The study subjects were the heads of eight groups. The Delphi survey was conducted by e-mail after a researcher explained the objective of the study to the heads. The research agenda was classified according to the Korean dental hygiene academic classification and the National Dental Hygiene Research Agenda classification. To compare the number of research agendas according to classification among the groups, we conducted a chi-squared test by using IBM SPSS 20.0. In total, 316 agendas were submitted. According to the Korean dental hygiene academic classification, there was a significant difference among the groups, and the agendas associated with clinical dental hygiene (36.7%) were the best. According to the National Dental Hygiene Research Agenda classification, there was no significant difference and the agendas associated with health promotion and disease prevention (27.8%) were the best. In conclusion, the Korean Dental Hygienists Association and affiliated groups demanded similar research agendas, corresponding to the purpose of each establishment. However, the groups did not seem to show unique characteristics according to the purpose of each establishment. In other words, the groups should corroborate such characteristics and suggest a corresponding agenda to establish specific areas of research in dental hygiene. Also, dental hygiene researchers should mark the academic classification of the studies they want to submit.

Background: This study aimed to evaluate ChatGPT’s performance accuracy in responding to questions from the national dentalhygienist examination. Moreover, through an analysis of ChatGPT’s incorrect responses, this research intended to pinpoint the predominant types of errors. Methods: To evaluate ChatGPT-3.5’s performance according to the type of national examination questions, the researchers classified 200 questions of the 49th National Dental Hygienist Examination into recall, interpretation, and solving type questions. The researchers strategically modified the questions to counteract potential misunderstandings from implied meanings or technical terminology in Korea. To assess ChatGPT-3.5’s problem-solving capabilities in applying previously acquired knowledge, the questions were first converted to subjective type. If ChatGPT-3.5 generated an incorrect response, an original multiple-choice framework was provided again. Two hundred questions were input into ChatGPT-3.5 and the generated responses were analyzed.After using ChatGPT, the accuracy of each response was evaluated by researchers according to the types of questions, and the types of incorrect responses were categorized (logical, information, and statistical errors). Finally, hallucination was evaluated when ChatGPT provided misleading information by answering something that was not true as if it were true. Results: ChatGPT’s responses to the national examination were 45.5% accurate. Accuracy by question type was 60.3% for recall and 13.0% for problem-solving type questions. The accuracy rate for the subjective solving questions was 13.0%, while the accuracy for the objective questions increased to 43.5%. The most common types of incorrect responses were logical errors 65.1% of all. Of the total 102 incorrectly answered questions, 100 were categorized as hallucinations. Conclusion ChatGPT-3.5 was found to be limited in its ability to provide evidence-based correct responses to the Korean nationaldental hygiene examination. Therefore, dental hygienists in the education or clinical fields should be careful to use artificial intelligence-generated materials with a critical view.

Colorectal polyps of mesenchymal origin are a rare group of colorectal disorders. A "mucosal Schwann-cell hamartoma," which is one type of polypoid lesion that originates from the mesenchyme, is a newly-proposed disease entity to be distinguished from the neurofibromas found in type-1 neurofibromatosis. This lesion is composed of pure Schwann-cell proliferation in the lamina propria and shows diffuse immunoreactivity for the S-100 protein. We report a case of a polypoid lesion of the colon with the features of this recently-proposed disease entity.

BACKGROUND: High cortisol levels are frequently observed in patients with severe infections are of prognostic value in sepsis. The aim of this study was to evaluate the clinical usefulness of serum cortisol in assessment for the severity of community-acquired pneumonia (CAP). METHODS: This study analyzed the results of 52 CAP subjects admitted in Changwon Fatima Hospital between July 2008 to May 2010. Total serum cortisol, infection markers such as C-reactive protein (CRP), procalcitonin (PCT) and CURB (Confusion, Uremia, Respiratory rate, Blood pressure)-65 were examined retrospectively. RESULTS: In clinically unstable subjects on admission day 4, baseline serum cortisol, CURB-65, and CRP were elevated significantly compared to those of stable subjects. Area under curve (AUC) of cortisol, CRP, and CURB-65 from ROC curves were 0.847, 0.783, and 0.724 respectively. In the subjects with serum cortisol > or =22.82 microg/dL, CRP, PCT, CURB-65 score, and mortality were significantly elevated. CONCLUSION: These findings suggest that measurement of serum cortisol in early stage may provide helpful information in the assessment of CAP severity.

Insulin autoimmune syndrome (IAS) is characterized by spontaneous hypoglycemia caused by insulin autoantibodies in the absence of exogenous insulin administration. Some drugs containing sulfhydryl compounds are known to initiate the onset of IAS. A 67-year-old female who had diabetes for 5 years visited the outpatient clinic at our institution due to diabetic peripheral polyneuropathy. She was prescribed alpha-lipoic acid (ALA), which contains two sulfur atoms. Two weeks later, she complained of recurrent hypoglycemic symptoms. We detected a high level of insulin and high titers of insulin autoantibodies. Her human leukocyte antigen (HLA) genotype included the DRB1*0406 allele, which indicates a high level of susceptibility to IAS. She was treated with prednisolone. After this episode, she experienced two more hypoglycemic events after taking ALA for diabetic neuropathy in other hospitals. As ALA can be used to treat diabetic peripheral polyneuropathy, physician discretion is advised based on the possibility of IAS due to ALA in diabetic patients.

BACKGROUND: Hypoglycemia is the most common therapeutic complication of diabetes mellitus and especially in elderly diabetic patients with diminished cardiac and cerebral circulation can cause serious tissue damage. Though many studies have attempted to evaluate hypoglycemia in IDDM or adult diabetic patients, few studies in the elderly. We have compared clinical characteristics of severe hypoglycemia in elderly diabetes with adult diabetes. METHODS: This study include 56 severe hypoglycemic patients who have admitted to emergency department of National Medical Center from march 1, 1992 to december 31, 1997. they are divided two group (adult group; 21, elderly group; 35) and authors investigate the cause, the symptom, the time of severe hypoglycemia, degree of education, treatment method in each group. RESULTS: 1) DM education was not well done in severe hypoglycemic patients. 2) The frequency of severe hypoglycemia in the elderly was more than adult (adult: 21 (38%), elderly 35 (62%)). 3) In both population, the most common symptom of severe hypoglycemia was neuroglycopenic symptom, especially in the elderly (adult: 57%, elderly: 77%). 4) Decreased food intake (49%) in the elderly and overdose of insulin (38%) in the adult were the most common cause of severe hypoglycemia. 5) Severe hypoglycemia occurred more often between midnight and 6 AM in the adult, between noon and 6 PM in the elderly. 6) The treatment of diabetes mellitus is insulin (71%) and oral hypoglycemic agent (29%) in the adult, oral hypoglycemic agent (51%) and insulin (49%) in the elderly. CONCLUSION: For prevention of severe hypoglycemia, we should emphasize the importance of DM education and especially elderly diabetic patients should be educated about the symptoms of hypoglycemia, the self-management of hypoglycemia, the need for a regular carbohydrate intake and more easy and effective diet program is require in elderly diabetes.
