Nitroblue tetrazolium dye reduction test is now widely used for early detection of bacterial infection. Practically nitroblue tetrazolium dye reduction test (N.B.T. test) gives certain clue to rule out any possibility of aseptic inflammation. Authors performed N.B.T. test for 80 orthopaedic diseases and 40 controls, and the results were as followings: 1. Forty-one of 60 subjects with bacterial infection had more than 10% formazan positive neutrophils, and 18 of 20 subjects without bacterial infection showed less than 10%. formazan positive neutrophils, The groups of the elevated N.B.T. responses were mainly the subjects who had osteomyelitis, soft tissue inflammation, pyogenic arthritis, and bone and joint tuberculosis. 2. The mean proportion of N.B.T. positive neutrophils was 3.8±2.78% in 40 controls, 4.7±4.23% in 20 nonifectious group 12.7±10.3% in 12 chronic osteomyelitis, 12.5±10.7% in 15 treated bone and joint tuberculosis, 20.9±15.65% in 15 untreated bone and joint tuberculosis and 20±10.70% in 11 pyogenic arthritis and 7 other soft inflammatory group. 3. In noninfectious group, 7 of 8 subjects with elevated ESR and 3 of 4 subjects with elevated body temperature revealed N.B.T. responses less than 10%. 4. In 23 subjects with the elevated N.B.T. responses as well as leukecytosis, 22 subjects were the groups of bacterial infection and rest 1 was noninfectious in nature. 5. Therefore, the N.B.T. test is found to be useful for the purposes of the early diagnostic aid of the bacterial infection and differential diagnosis between bacterial infections and other diseases.

BACKGROUND: Midazolam relaxes airway smooth muscle. The aim of this study is to evaluate the influence of flumazenil or verapamil on the relaxation effects of midazolam in tracheal smooth muscle of guinea pig. METHODS: After isolating guinea-pig tracheal preparations, the maximal tracheal tones were induced by 2 10(-7) M carbachol. When tracheal tones stabilized, midazolam was added cumulatively (10(-6), 3 10(-6), 10(-5), 3 10(-5), 10(-4) M, n=14) with or without flumazenil (10(-6) M, n=15) and verapamil (10(-5) M, n=13) to obtain the concentration-relaxation curves, and then the ED50 and ED95 calculated. RESULTS: Midazolam decreased maximal tracheal smooth muscle tones in concentration-dependent manners. Pretreatment with flumazenil had no effect on the midazolam-induced relaxation. Verapamil enhanced the relaxation effect of midazolam. CONCLUSIONS: Midazolam relaxes airway smooth muscle and has synergistic effect with calcium channel blocker, verapamil.

PURPOSE: The purpose of this study was the development of a comprehensive nursing intervention program for the client with acute lymph stasis and stage I lymphedema. METHOD: The Quasi-experimental design using a non-equivalent control group was used. The subjects were 22 stroke patients with lymph stasis in the control group and 23 patients in the experimental group. The complex physical therapy of Casley-Smith was carried out to the control group for 10 hours, and comprehensive nursing intervention for the experimental group was carried out for 60 minutes. The data for this study was gathered from Feb. 2002 until June 2002 and pertains knowledge about lymphedema, self-care for managing lymphedema, and circumferences of affected limbs. Data was analyzed by mean, standard deviation, x2-test, and t-test. RESULT: The changes in knowledge about lymphedema, self-care practices, and circumference of affected limbs after nursing intervention did not show significant differences between control group and experiment group. CONCLUSION: It can be concluded that comprehensive nursing intervention had more efficiency than complex physical therapy in the treatment of edema for stroke patients because of it's simplicity and time saving. Thereby, the comprehensive nursing intervention program developed in this study would be a useful therapy for the clients with lymph stasis and early stage lymphedema.

PURPOSE: The purpose of this descriptive study was to gain basic data to develop a self-care protocol for the lymphedema patients. METHOD: The subjects of this study consisted of 115 patients with lymphedema from 8 hospitals and two community health and welfare centers in Busan and Seoul. The data was collected with questionnaire by self reporting of patients between March 2001 and December 2001. Data was analyzed by mean and percentage. RESULT: For self-care activities in daily life, compliance of 'use skin care preparations', 'use heat and cold', 'protect from local compression on affected limbs', 'protect from insect biting', 'use aids to protect affected limbs', 'take diuretics and take protein diet' did not reach to 50%. For self-care activities related to complex physical therapy, 28.7% of subjects complied with compression garment, 14.8% with manual lymph drainage, and 13.0% with exercise. 20.0% of subjects tried to treat with acupuncture and 13.9% with heat therapy. CONCLUSION: From this study, it is suggested that patients need to get a self-care education with correct information about self care activities and health care professionals need to develop more convenience self-care techniques of massage and exercise.

BACKGROUND/AIMS: Recent studies suggest possibility of continuous and prolonged liver ischemia exceeding one hour. We compared mortality rates, liver function, serum Interleukin-6(IL-6) concentration and liver cell necrosis after continuous and intermittent hepatic ischemia in rats. METHODS: Sixty rats were divided into 6 groups to compare 7 day mortality rate. Continuous and intermittent left hepatic inflow occlusion was performed for a total period of 45, 60 and 90 minutes. In a separate study, following 90 minutes continuous or intermittent ischemia, systemic blood was sampled at 0 minute, 6 hours and 24 hours after final clamp release for measurement of SGOT, SGPT and IL-6. Pathologic examination was performed 24 hours or 7 days after reperfusion accordingly. RESULTS: There were no differences in the mortality rates within seven days. There were no differences in the level of SGOT, SGPT and IL-6 between each experimental group. In a pathologic examination, similar liver cell necrosis was found in each group until 24 hours of reperfusion. However, at 7 days after reperfusion, significantly higher grade of hepatic necrosis was noted in the group having continuous ischemia compared with intermittent ischemia of 90 minutes(p<0.05). CONCLUSION: Continuous ischemia is associated with significant risk in the aspect of pathologic study, although it did not affect short term mortality rates.

PURPOSE: The objective of this study is to investigate changes of chest wall shape and chest compression site according to increasing age. METHODS: This study is based on 99 patients who underwent chest computed tomography (CT) scans, and classified them into six groups according to age, from 30's to 80's. Using images of sagittal and coronal sections of chest CT scans, we found the chest compression site, which is in the lower half point of the sternal body. We calculated the vertical length to the left ventricular outflow tract and to the center of the left ventricle from the lower half point of the sternal body. We also estimated the antero-posterior (AP) diameters of the lower half region of the chest to determine how the shape of the chest changes according to increasing age. In addition, we calculated the horizontal length between the surface of the chest and center of the left ventricle. Data are classified and estimated according to age group. RESULTS: The AP diameter at the compression site was not significantly changed according to increasing age. The vertical length from the compression site to the center of the left ventricle and left ventricular outflow tract was significantly changed according to increasing age. The depth between surface of body and center of left ventricle was not significantly changed according to increasing age. CONCLUSION: There is a tendency where the position of the left ventricular outflow tract and center of the left ventricle show lower positioning according to increasing age. AP diameter at the compression point was not significantly changed according to increasing age.

PURPOSE: Gastric cancer is believed to be a disease of the elderly, and rarely occurs in young patients. The aim of this study was to analyze the clinicopathological and prognostic factors related to young gastric cancer patients. METHODS: A total of 877 patients with gastric cancer from 1995 to 2004 in a secondary referral center in Suwon City were enrolled in this study. The clinicopathological features of the young (aged<40 years) gastric cancer patients were compared with those of the older (aged > or =40 years) patients. The overall survival was the main outcome measure. The survival curves were constructed using the Kaplan-Meier method, Univariate analysis was performed using the log-rank test, and multivariate analysis was performed using with Cox regression. A P value<0.05 was considered significant. RESULTS: Of the 877 patients, 65(7.4%) were in the young age group. The mean age of this group was 34.9 years (range, 19~39 years). The male-to-female ratio of the patients younger than 40 was 1.24/1; whereas the ratio was 2.07/1 in those older than 40. 7.7 percent of the patients had a family history of gastric cancer. A significantly higher percentage of young patients had a poorly differentiated histology than the older patients (P=0.0001). Twenty-three patients (38.9%) were stage III or IV disease, whereas 36 patients (61.0%) presented with stage I or II disease. A resection with a curative intent was undertaken in 53 patients (81.5%), and a resection with a palliative intent was performed in 12 patients (18.4%). With a mean follow-up of 39 months, the disease-specific 5-year survival rates were similar to those observed in the older group of patients. The variables with a significant impact on survival were a curative resection, a lymph node metastasis, lymphatic invasion, peritoneal metastasis, and adjuvant chemotherapy. CONCLUSION: There were no significant differences in the clinicopathological characteristics and clinical outcome of a gastric adenocarcinoma between the younger and older patients. The important prognostic factors were curability, lymph node metastasis, lymphatic invasion, peritoneal metastasis, and adjuvant chemotherapy.

Emergency physicians often have to treat patients suffering from testicular pain. Testicular torsion is a critical disease which can, in the worst situation, require orchiectomy. Testicular torsion is more common among neonates and adolescents than adults, and there are very few adults reported to have testicular torsion. There are several cases of testicular torsion among adults aged 20 to 40. However, there have been almost no reports of patients with testicular torsion over the age of 50. Patients over the age of 50 have a greater possibility of a delayed diagnosis. Therefore, they also have a greater possibility of requiring an orchiectomy. In our case, 57-year-old male patient complained of testicular pain that developed during his sleep after golf practice. After exploratory surgery, he was diagnosed as having testicular torsion. In conclusion, emergency physicians should consider the possibility of testicular torsion when older adults complain of testicular pain. Also, patients who suffer from intermittent testicular pain show higher rates of developing testicular torsion.

Fluconazole is a fungistatic agent that is used for treating systemic and superficial fungal infections like onychomycosis and tinea pedis. Various adverse effects of fluconazole have been reported regardless of the total dosage and the duration of treatment. We consider the number of patients who visit the emergency room with nonspecific symptoms that are related to antifungal agents are not inconsiderable. In this case, 44-year-old male patient experienced mental change during taking fluconazole to treat tinea pedis. The understanding of the side effects and the drug interactions with antifungal agents like fluconazole can help to treat patients with nonspecific symptoms that are related to antifungal agents.
