PURPOSE: The purpose of the study is to find whether there is any effect on shortening the length of stay of long term patients due to issuing of hospitalization sheets by emergency department. METHODS: For the investigation, 27,948 patients who resided in hospitals over 6 hours from 2006 to 2007 were chosen as the subjects. The main materials for the investigation were various time variables according to the medical records. For the verification of each factor, Student's t-test and Pearson' correlation coefficient were used. RESULTS: There was statistically significant difference in regard to length of stay (p<0.01). The departments related to internal medicine showed that they required longer times in every aspect compared to those of non-internal medicine. There were statistically significant differences (p<0.01) in regard to the time of patients' length of stay and the time of issuing sheets for hospitalization according to the numbers of related department. However, there was no meaningful difference in regard to the waiting time for hospitalization. CONCLUSION: In conclusion, in the cases of long term patients who stayed over 6 hours in 2007 when the random sheets for hospitalization were issued by emergency department, the length of stay was significantly reduced. It was found that the time was more increased in the departments of internal medicine than the departments of noninternal medicine and when the related sub departments increased.

PURPOSE: Procalcitonin (PCT) is a good marker of infection but is still not routinely used. Here, we assessed the usefulness of a semi-quantitative procalcitonin test kit (PCT-Q(R)), a rapid and simple test for evaluating sepsis in the emergency department. METHODS: We recruited 80 patients who visited the emergency center and with systemic inflammatory response syndrome (SIRS). Patients were classified into 4 groups according to PCT levels using PCT-Q[Ed-Trademark signs only have to be given one time in a document]. Mortality rate, bacteremia, severity score, and severity of sepsis (SIRS/sepsis/severe sepsis/septic shock) were assessed with the criteria of the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference. We calculated a receiver operating characteristic curve (ROC curve), cut-off value, and the related diagnostic parameters of each cut-off value. RESULTS: Higher PCT levels were significantly associated with increased mortality, bacteremia, and severity scores. PCT levels could discriminate between sepsis and severe sepsis at a threshold of 2 ng/ml. CONCLUSION: PCT-Q is a prognostic marker of infectious disease, but low levels do not always indicate a good prognosis. PCT levels increase with aggravation of sepsis, especially at values greater than 2 ng/ml for severe sepsis.

BACKGROUND: Follicular patterned thyroid nodules with incomplete nuclear features of papillary thyroid carcinoma (FTN-INPTCs) are difficult to diagnose, and their biological behavior and association with follicular variants of PTC (FVPTCs) have not yet been established. The aim of this study is to determine immunohistochemical and molecular characteristics of FTN-INPTCs. METHODS: We investigated immunohistochemical features (galectin-3, HBME-1, CK19, fibronectin-1, CITED1), BRAF V600E mutation and RASSF1A promoter methylation status in 30 FTN-INPTC cases, along with 26 FVPTCs, 21 follicular adenomas (FAs) and 14 nodular hyperplasias (NHs). RESULTS: Expression of galectin-3, HBME-1, CK19 and CITED1 was significantly higher in FTN-INPTCs than in FAs or NHs, but expression of galectin-3, CK19 and fibronectin-1 was lower in FTN-INPTCs than in FVPTCs. The BRAF V600E mutation was not detected in the benign nodules or FTN-INPTCs, whereas 57% of FVPTCs had the mutation. RASSF1A promoter methylation was higher in FTN-INPTCs than in benign nodules but there was no difference between FTN-INPTCs and FVPTCs. CONCLUSIONS: Our results represent the borderline immunohistochemical and molecular characteristics of FTN-INPTC. We conclude that FTN-INPTC is an intermediate lesion between a benign nodule and a FVPTC, and that it is pathogenetically related to FVPTC.

OBJECTIVES: We aimed to find out the relationship between the regional suicide rates and the percentages of medical aid in the elderly in Korea. METHODS: Suicide rates of the elderly in 16 upper-level local governments from 2007 to 2009 were calculated using 'Cause of Death Statistics' and 'Annual Report on Live Births and Deaths Statistics' from Korea National Statistical Office. The percentages of medical aid persons among the elderly in 16 upper-level local governments were calculated using 'National Health Insurance Statistical Yearbook' from Health Insurance Review Agency and National Health Insurance Corporation. The correlation between the suicide rates and the percentages of medical aid in the elderly was measured. RESULTS: There was no significant correlation between the suicide rates and the percentage of medical aid in the elderly in 16 upper-level local governments. But significant negative correlation was found when only the old-elderly or the old women were analyzed. And the significant negative correlation was also found when only 8 local governments except the major cities and the national capital area were included for analysis. CONCLUSION: Medical aid system could be helpful to reduce the suicide rate in the old-elderly or the old women in Korea. And this effect might be intensified in non-metropolitan and non-capital area.
