Purpose: This study identified the characteristics differentiating node-first presentation of Kawasaki disease (NFKD) from bacterial cervical lymphadenitis (BCL) and typical Kawasaki disease (KD). Methods: From July 2007 to June 2015, the medical records of patients with BCL, NFKD, and typical KD were retrospectively reviewed. We analyzed and compared the demographic, clinical, laboratory, and imaging characteristics of the cohorts. Results: Twenty-two patients with BCL, 37 with NFKD, and 132 with typical KD were included in this study. Patients with BCL had longer durations of hospitalization than patients with NFKD. Bilateral and multiple enlarged cervical lymph nodes were associated more with NFKD than BCL. Compared with BCL patients, NFKD patients had lower platelet counts, higher percentages of neutrophils, and higher C-reactive protein (CRP) levels. NFKD patients were older and presented with higher white blood cell counts, percentages of neutrophils, absolute neutrophil counts, and CRP levels as well as lower platelet counts and alanine aminotransferase levels than typical KD patients. Conclusions: In febrile patients with cervical lymphadenopathy, the combination of bilateral and multiple enlarged nodes, low platelet count, high percentage of neutrophils, and high CRP levels should prompt consideration of NFKD for prevention of delayed diagnosis of KD.

Human granulocyte colony-stimulating factor (hG-CSF) is a hematopoiesis agent that principally affects the differentiation of neutrophils in the bone marrow. At present, recombinant hG-CSF is used successfully in the treatment of chemotheraphy-induced neutropenia and its indication has been expanded to bone marrow transplantation and aplastic anemia. In this study, we have constructed rhG-CSF secretion plasmid pYRC1 in which OmpA signal sequence/hG-CSF gene was expressed under the control of the T7 promoter. rhG-CSF produced in E. coli BL21 (pYRC1) grown at $37{\circ}C$ was found in aggregates. However, 15% of the periplasmic protein was soluble rhG-CSF when the E. coli BL21 (pYRC1) was cultured at $25^{\circ}C$ for 7 h in the modified MBL medium containing 10 g/$\ell$ glucose with 10 $\mu$M IPTG induction. The production of soluble rhG-CSF in E. coli BL21 (pYRC1) using fed batch culture was also studied. In the fed batch culture system, the final yield of rhG-CSF produced from E. coli BL21 (pYRC1) was increased from 4.4 mg/$\ell$to 24 mg/$\ell$by controlling the specific growth rate from $0.43 h^{-1}$ to $0.14 h^{-1}$, and optimizing the time of induction.

We report a case of an 18-month-old girl with glycogen storage disease type Ib (GSD Ib). Her neutrophil counts had gradually decreased to less than $500/{\mu}L$ by the age of 3 years. However, there were no recurrent bacterial infections. Mutation analysis of the glucose-6-phosphate translocase (G6PT) gene revealed a compound heterozygous missense mutation (Ala148Val/Gly273Asp).

Purpose: This descriptive study aimed to compare the perception of the acceptable foods for the neutropenic diet between nurses and patients by food type. Methods: The participants were 225 nurses working at chemotherapy wards and 71 patients in chemotherapy treatment. Data were collected with a self-administered questionnaire from January 2 to February 24, 2012, and analyzed with SPSS 12.0 program using descriptive statistics and the ${\chi}^2$-test. Results: Eighty-eight point eight percent of nurses and 76.1% of cancer patients thought the patients needed the neutropenic diets. The most important decisional criteria to determine dietary restriction was neutrophil count for nurses and food type for patients. The two groups showed significantly different allowance to raw fruits and raw vegetables, sterilized canned juice, fried vegetables, yogurt, uncooked tofu, salted fish, cooked fish, cooked shellfish, uncooked grain powder, jellified food, home-made bread/cookies, nuts including peanuts, instant coffee or tea and tea brewed. In general, patients were more permissive about the neutropenic diet than nurses. Conclusion: It is recommended to consider patients' preference as well as nurses' professional knowledge and publish standardized clinical diet guidelines for neutropenic patients with collaboration between nurses and patient representatives.

Purpose: The purpose of the study was to identify levels of anxiety, stress hormone, lymphocytes, and neutrophils of the nursing students before an examination and to examine effects of social support on those variables related to taking examinations. Methods: Thirty eight healthy nursing students participated. They completed the questionnaire including state anxiety, test anxiety (VAS scale) and social support two weeks before the exam and again just before the exam. Simultaneously, a venous sample for ACTH, cortisol, lymphocytes & neutrophils count was drawn by a trained nurse. Descriptive statistics, paired t-test, student t-test, and Pearson's correlation with SPSS/WIN 14.0 were used to analyze the data. Results: Test anxiety scores and cortisol level on the exam day showed a significant increment compared with those on the non-exam day. The participants with higher levels of total social support scores showed significantly lower state anxiety on the exam day than those with lower levels of total social support scores. Conclusion: These data indicate a possible alteration in cortisol responsiveness to academic stress in nursing students. Social support would play an important role in modulation of academic stress.

In acute lung injury (ALI) by lipopolysaccharide (LPS), the underlying cause of infiltration and migration of neutrophils into the alveoli is considered to be from increased production of platelet-activating factor (PAF) in the pulmonary surfactant lining the alveolar lumen. In this study I partially confirmed this concept. LPS increased lung leak and the infiltration of neutrophils in the lung of rats given LPS intratracheally. The migration of neutrophils into the lung, which had caused oxidative stress, was also morphologically identified. I verified that the metabolism of the pulmonary surfactant was affected and that there was increased production of PAF in the pulmonary surfactant, both of which are considered to contribute to ALI by LPS in rats.

Purpose : Kawasaki disease is notorious for coronary arterial complication which is usually developed as a febrile disease in early childhood. Increased polymorphonucleus(PMN) cell levels in acute phases may be associated with the pathophysiology of Kawasaki disease. We studied the relationship between coronary arterial dilatation and elastase activity which was excreted from PMN cell and roles as an important factor for vasculitis. Methods : Ten patients diagnosed with Kawasaki disease in Yonsei University Medical Center were examined between November, 2001 and January, 2002. In addition, 15 patients with other febrile diseases were also examined. Echocardiography was done in patients with Kawasaki disease on the first day of admission and four weeks after the onset of the disease. At each time, venous samples were drawn and separated into plasma and leukocytes. In patients with other febrile disease, samples were drawn on admission. Elastase activities in plasma and neutrophil extracts were measured. Results : The significant increased plasma elastase activity, $6.19{\pm}0.74U/mL$, found in Kawasaki disease patients compared with the other febrile disease patients, $4.86{\pm}1.17U/mL$(P<0.05). And there was no significance between the above two diseases in terms of the elastase activity in neutrophil extracts. The relationship between initial elastase activity and the coronary arterial complication which was shown in subacute phase wasn't significant. Conclusion : Plasma elastase activity was increased in Kawasaki disease significantly, but the initial plasma elastase activity in the acute phase could not reflect the range of coronary arterial complication.

Background : The measurement of adenosine deaminase(ADA) level in pleural fluid is useful in the diagnosis of tuberculous(TB) pleural effusion. However, ADA is also elevated in other diseases such as malignancy, bacterial infections, empyema, and collagen vascular disease, ADA alone has limited value. The object of this study is to determine diagnostic usefulness of the combined use of ADA value with lymphocyte/neutrophil ratio(L/N ratio) rather than the use of ADA alone. Method : We evaluated 198 patients(age=$55.9{\pm}12.9$, M/F=2.7:1) with pleural effusion who had admitted in Gyeong-sang National University Hospital from Jan. 1999 to Dec. 2001. retrospectively. Patients were divided into four diagnostic groups: TB pleural effusion(n=91), parapneumonic effusion(n=65), malignant effusion(n=21), and transudative effusion(n=13). The ADA level, differential cell count, biochemistry, cytology, and microbiology of each diagnostic groups were evaluated. The sensitivity, specificity, negative predictive value(npv), positive predictive value(ppv) and efficiency were calculated at each ADA values and combined ADA value with various L/N ratios. Results : The ADA level in TB pleural effusion was significantly higher than that of parapneumonic effusion, malignant pleural effusion, and transudative effusion(p<0.05). Sensitivity, specificity, ppv, npv and efficiency at $ADA{\geqq}50$ IU/L in the diagnosis of TB pleural effusion were 89.0%, 82.2%, 81.0%, 89.8% and 85.5% respectively. When $ADA{\geqq}50$ IU/L was combined with lymphocyte/neutrophil $ratio{\geqq}0.75$, sensitivity, specificity, ppv, npv, and efficiency were 83.5%, 96.3%, 95.0%, 87.9% and 90.5% respectively. Specificity, ppv and efficiency were increased with combination of ADA value and L/N ratio. Conclusion : Combination of ADA value and L/N ratio in pleural effusion is more useful than ADA value alone in the diagnosis of TB pleural effusion.
