PURPOSE: Acute appendicitis has atypical clinical findings that make accurate preoperative diagnosis difficult. The aim of this study was to investigate the usefulness of laboratory analyses, especially total leukocyte count (WBC) and neutrophil count, C-reactive protein (CRP) in the diagnosis of acute appendicitis. METHODS: Sixty-nine patients who visited to the Department of Surgery, Sangju St. Mary's hospital with the diagnosis suspected acute appendicitis were studied. WBC, neutrophil count, CRP, and erythrocyte sedimentation rate (ESR) were analysed. Surgery for acute appendicitis was performed in fifty-four patients. According to histopathological findings of the appendix, the patients were divided into four groups: complicated (20 patients with perforated & gangrenous type), suppurative (9 patients), phlegmonous (25 patients), and normal (15 patients). The sensitivity and specificity of the laboratory tests in the diagnosis of acute appendicitis were calculated. RESULTS: The sensitivity of WBC>10, 000/mm3, neutrophil count>70% or >7, 000/mm3, and CRP>12 mg/L in acute appendicitis was 68.5%, 85.1%, and 74.0%, and the specificity was 86.0%, 73.3%, and 80.0% respectively. The combination of neutrophil count or CRP was 94.4% sensitivity. The severity of appendicitis had positive relationship with WBC, neutrophil count, and CRP (P=0.0001, P<0.0001, and P= 0.0014, respectively). The appendicitis and normal groups were significantly different in WBC, neutrophil count, and CRP (P<0.05). CONCLUSION: WBC, neutrophil count, and CRP have diagnostic value among the myriad causes of right lower quadrant abdominal pain and show a positive relationship with the severity of appendicitis.

Epithelioid hemangioendothelioma(EH) is a low-grade tumor of vascular endothelial cell origin, which most commonly occur in the lower extremities of middle-aged patients with an equal gender distribution. It may occur on internal organs such as the liver or lung or bones. A 54-year-old woman who had a history of metastatic adenocarcinoma of unknown origin on the right inguinal lymph node, was presented to us because of a 1.0 x 1.0cm-sized and 2 x 2cm-sized two subcutaneous nodule on her right shin. On H & E stain, there were nests of round nucleated, polygonal, vacuolated cells, some of which contained fragmented erythrocytes. Factor VIII related antigen, CD31 was positive. A diagnosis of epithelioid hemangioendothelioma was established based on histologic, immunohistochemical studies. Wide excision was performed. There was no recurrence nor the development of new lesions so far.

OBJECTIVE: To ananlyze the direct effect of nitric oxide (NO), generated from sodium prusside (SNP) on the embryo developments in reproductive process. DESIGN: ova from mouse were treated to allow fertilization in in vitro culture. And the samples of fertilized ova were alloted into five alliqutos. Each alliquot was cultured in media treated with either concentration at 0 (n=92), 25microM (n=84), 50microM (n=80), 100microM (n=77), 500microM (n=54) of SNP. Main Outcome MEASURE: Rates of embryonal cell cleavages, viability and cell morphology were assessed during in vitro fertilization and culture. RESULTS: As analyse the cell cleavage at 24 hours after in vitro culture of fertilised egg in variuos NO concentration, all of egg cells of each alliquot were developed to 2~4 cell stage. But the alliquot of egg cells treated with 500microM, which were totally degenerated. And also all embryonal cells of each alliquot were developed to 8 cell stage and morula stage on culture continuosly. And the embryonal cells of each alliquot were analysed at 24 and 48 hours following the in vitro culture. The rates of cell fragmentation and fusion were 4.2+/-3.4% in control group which is not treated with NO, while experimental groups was high, as rated 23.4+/-6.2% in 25microM, 28.2+/-5.7% in 50microM and 32.1+/-6.4% in 100microM concentration of NO. Accordingly the rate of abnormal morphology of embryonal cell in control was lower significantly than that in each alliquot of experimental groups (p<0.05). And the degenerated rates of embryonal cells were 0% in control, 17.8+/-6.7% in 25microM, 23.6+/-4.7% in 50microM and 26.8+/-11.2% in 100microM at 8 cells and morula on culture of 48 and 72 hours. On the examination of embryonal cells developed to blastocyst through in vitro culture, the rates of degenerated cells were 16.8+/-7.2% in control, 37.5+/-6.2% in 25microM, 73.4+/-4.6% in 50microM, 100% in 100microM. CONCLUSION: This results suggeted that the No in any concentrations is harmful on embryos in view of morphology as well as viability of cell, and the toxicity of No on embryo is stronger at condition in higher concentration of NO.

Hypotension is one of the well-known complications following spinal anesthesia, and Trendelenburg position seems to have been used as one of the management of it. But, Trendelenburg position generally raises spinal anesthetic level with the use of hyperbaric tetracaine, and blood pressure may even further decrease. If simple elevation of lower extemities can prevent hypotension successfully without raising spinal anesthetic level following hyperbaric spinal anesthesia, there will be a possibility for us to replace Trendelenburg position with the elevation of lower extremities. We examined 50 cases of hyperbaric spinal anesthesia followed by elevation of lower extremities with the angles of l5 and 30 degrees. At each case, hydration with 10 ml per Kg was performed during the fixation time (about 30 minutes) and then, blood pressure(systolic and diastolic), heart rate were checked with the time-interval of 1 and 2 minutes for each angle. The paired T-test showed that systolic and diastolic blood pressure after spinal anesthesia was increased in all cases with mean values of 2.74~5.68 mmHg for systolic blood pressure(p<0.05) and 3.26~7.22 mmHg for diastolic blood pressure(p<0.05), and that heart rate was decreased by 3.54-5.82 beats per minute(p<0.05). In conclusion, simple elevation of lower extremities and routine hydration therapy seemed to elevate blood pressure, making it possible for us to consider elevation of lower extremities to prevent hypotension without raising spinal anesthetic level in routine hyperbaric spinal anesthesia.

Objective: Agriculture is a hazardous industry. However, previous studies have focused on injuries to agricultural workers without comparison with injuries to nonagricultural workers. Therefore, we compared the clinical characteristics and outcomes of injuries reported at an emergency department (ED) between agricultural workers and nonagricultural workers. Methods: We established a prospective ED-based agricultural injury surveillance system at a tertiary university hospital. Adult patients visiting the ED for an injury were divided into farmer and non-farmer groups depending on their engagement with agriculture. Using an adjusted multivariate analysis and propensity score matching (age, sex, inhabitant, and insurance type), we compared the clinical characteristics and outcomes of injuries between the farmer and non-farmer groups. Results: In total, 38,556 injured adult patients (37,746 in the non-farmer group and 810 in the farmer group) were available for the unmatched sample analysis. The 1,620 matched subjects were equally classified after one-to-one nearest-neighbor propensity score matching. A multivariate logistic regression analysis of the unmatched sample revealed higher adjusted odds ratios (ORs) for intensive care unit admission (adjusted OR, 1.752; P=0.003) and overall surgery (adjusted OR, 1.870; P<0.001) in the farmer group. In contrast, univariate logistic regression analyses of the propensity score–matched sample found a higher OR in the farmer group only for overall surgery (OR, 1.786; P<0.001). Conclusion Injuries of agricultural workers had higher odds only of requiring surgery; differences in injury-related mortality between groups were not statistically significant in either the matched or unmatched sample analyses.
