BACKGROUND: Unlike other diseases, the management of sepsis has not been fully integrated in our daily practice. The aim of this study was to determine whether repeated training could improve compliance with a 6-h resuscitation bundle in patients with severe sepsis and septic shock. METHODS: Repeated education regarding a sepsis bundle was provided to the intensive care unit and emergency department residents, nurses, and faculties in a single university hospital. The educational program was led by a multidisciplinary team. A total of 175 adult patients with severe sepsis or septic shock were identified (88 before and 87 after the educational program). Hemodynamic resuscitation bundle and timely antibiotics administration were measured for all cases and mortality at 28 days after sepsis diagnosis was evaluated. RESULTS: The compliance rate for the sepsis resuscitation bundle before the educational program was poor (0%), and repeated training improved it to 80% (p < 0.001). The 28-day mortality was significantly lower in the intervention group (16% vs. 32%, p = 0.040). Within the intervention group, patients for whom the resuscitation bundle was successfully completed had a significantly lower 28-day mortality than other patients (11% vs. 41%, p = 0.004). CONCLUSIONS: Repeated education led by a multidisciplinary team and interdisciplinary communication improved the compliance rate of the 6-h resuscitation bundle in severe sepsis and septic shock patients. Compliance with the sepsis resuscitation bundle was associated with improved 28-day mortality in the study population.

This study identified an effective control method for periodontitis by investigating the association between blood levels of vitamin D and periodontitis in Korean elderly based on raw data from the fifth Korea National Health & Nutrition Examination Survey of 2010 (KNHANES). In this study, 1,021 adults over 65 years of age were evaluated based on data from the KNHANES. Periodontal disease was assessed using community periodontal index (CPI), with CPI codes ≥3 defined as periodontitis. Blood levels of vitamin D were measured from blood samples and divided into four groups (first quartile: ≤13.23 ng/ml, second quartile: 13.24∼16.95 ng/ml, third quartile: 16.96∼21.58 ng/ml), and fourth quartile >21.59 ng/ml). Using multiple logistic regression analyses, the variables were adjusted for general characteristics, oral health-related characteristics, health-related characteristics, and bone mineral density. The statistical analysis was performed using the SAS (ver. 9.2). The results of this study are as follows: the prevalence of periodontitis was 42.6% in Korean elderly. After adjusting for general, oral health-related, and health-related, the risk of periodontitis in the first quartile group was 1.74 times (95% confidence interval [CI], 1.02∼2.98) higher than that of the fourth quartile group (p=0.041). After adjusting for general, oral health-related, and health-related characteristics as well as bone mineral density, the risk of periodontitis in the first quartile group was 1.73 times (95% CI, 1.02∼2.96) higher than that of the four quartile group (p=0.042). There was a significant relationship between blood vitamin D level and periodontitis in Korean elderly. For the prevention of periodontitis, factors related to vitamin D should be considered along with other risk factors.

PURPOSE: To investigate the clinical results and safety of the acellular dermal allograft (SureDerm(R), Hans Biomed co., Korea) as a new spacer graft in anophthalmic socket contracture. METHODS: We grafted SureDerm(R) as the replacing spacer in 8 patients for the treatment of anophthalmic socket contracture. Under local anesthesia, SureDerm(R) was sutured at the levator aponeurosis and upper margin of the tarsus using 6-0 Vicryl in the upper lid. In the lower lid, SureDerm(R) was sutured at the tarsal conjunctiva and lower margin of the incised conjunctiva. The patients were followed-up individually for 6 to 15 months. RESULTS Surgical results in all 8 eyelids (6 lower lids, 2 upper lids) were satisfactory. The grafted SureDerm(R) survived in all patients with little contracture. There were no other complications such as infection, rejection, or exposure. CONCLUSIONS: We consider SureDerm(R) a good replacing spacer material for the treatment of anophthalmic socket contracture.

Airway hyperresponsiveness is a consistent feature of asthma. Since the airway smooth muscle is hyperresponsive to a number of different stimuli operating through many different mechanisms, it is attractive to speculate that the abnormality may reside in the airway smooth muscle itself. Animal model of asthma is needed to unravel possible mechanisms underlying airway hyperresponsiveness and also to develop new therapeutic approaches. However, there are few reports showing that airway smooth muscle from animal asthma model is indeed hyperresponsive. In addition, sensitizing and provoking doses of allergen were different each other ambng the studies on animal asthma model. The aim of this study was to determine an appropriate sensitizing and provoking dose of allergen to induce a maximum airway hyperresponsiveness. Eighty-four male Sprague-Dawley rats were actively sensitized with a subcutaneous injection of 0, 10, or 1000/gg ovalbumin(OA) and 14 days later they were provoked with 0, 1, or 5 % OA aerosols. One day after the provocation, serum levels of OA-specific IgE, cell numbers in bronchoalveolar lavage fluid (BALF), and in vitro isometric contractile responses of the isolated tracheal smooth muscle(TSM) to 120 mM KC1, acetylcholine(ACh, 0.1~ 1000/micro meter), electrical field stimulation (EFS, 0.5~100Hz), serotonin(5-HT, 0.014 100/micro meter), and OA(10, 50, or 250 micro gram/ml) were measured. The results were as follows; 1) When 38 OA-sensitized rats were exposed to OA aerosols in vivo early asthmatic responses(EAR) were observed in 20(52.6%) rats. In vitro isometric contractile forces of TSM from rats with EAR were stronger than those from rats without EAR. 2) The maximal contractile responses to KC1 and EFS were significantly higher in rats only sensitized with OA compared with those in controls. The maximal response to ACh was significantly related to OA-specific serum IgE level(r=0.40, p%0.05), and the latter was in turn significantly related to the BALF eosinophil count(r=0.67, p<0.01). 3) When 10 microgram OA-sensitized rats were analyzed, the maximal response to KC1, ACh, EFS, and 250 micro gram/ml OA were lower in OA-provoked rats compared to those in saline-provoked control rats, in which 5% OA-provoked rats had a lower response than 1% OA-provoked rats. 4) The sensitivity of TSM to ACh was significantly higher in 10/micro gram OA-sensitized & OA-provoked rats, and the sensitivity to EFS was also significantly higher in 10/~g OA-sensitized & 5% OA-provoked rats compared to that in controls(p<0.05). 5) There was a significant correlation between the sensitivity of TSM to EFS and the counts of eosinophil or of lymphocytes in BALF(for eosinophil, r=-0.30; p<0.05, for lymphocyte, r=-0.35; p<0.05), or OA-specific serum IgE level(r=-0.46, p<0.01) in OA-sensitized & OA-provoked rats. This relationship was maintained in the data obtained only from 10 micro gram OA-sensitized & 5% OA-provoked rats. 6) The ratio of EFS-sensitivity to ACh-sensitivity was significantly lower in OA-sensitized & OA-provoked rats compared to that in controls or rats only sensitized with OA(p%0.05). 7) The Schultz-Dale phenomenon occurred in an in vitro dose-dependent manner. However, the inhaled provocation with OA in vivo resulted in a decrease in the contractile response to OA in vitro. There was a significant correlation between OA-specific serum IgE level and isometric response to 250 micro gram/ml OA(r=0.36, p<0.01). These results suggest that sensitization and provocation in vivo with OA in rats induces hypersensitivity of airway smooth muscle to cholinergic stimuli through an allergic inflammatory mechanism. The sensitivity was highest when sensitized to 10 micro gram OA and exposed to 5% OA aerosols.

OBJECTIVES: The differentiation of tuberculous effusion from the other causes of exudative pleural effusion remained difficult even with aids of biochemical analyses and pleural biopsy. As the pathophysiology of tuberculous pleural effusion is an enhanced cell mediated immunity, Adenosine deaminase(ADA) and various cytokines including Inteferon-γ, tumor necrosis factor alpha(TNF-α) are considered as useful diagnostic tools in differentiating exudative pleural effusion The author would like to demonstrate the diagnostic usefulness of TNF-α in the differentiation of exudative pleural effusion, and compared the discriminating ability of TNF-α with ADA. METHODS: Pleural fluids obtained from 80 patients (tuberculous : 39, malignant : 31, parapneumonic : 10) with exudate pleural effusions were processed for cell counts and biochemical analysis including ADA and TNF-α RESULTS: Tuberculous pleural fluid showed higher levee of ADA and TNF-α, 48.7α 32.7U/L and 184.1±214.2pg/mL than that of non-tuberculous effusion 26.0α41.3U/L and 44.1α114.2pg/mL, respectively (ADA, TNF-α : p<0.05, p<0.01). Receiver operating characteristics(ROC) curves were generated for ADA and TNF-α, and the best cut-off value for adenosine deaminase and TNF-α were considered as 30U/L and 15pg/ml, respectively. Comparing the area under the ROC curves, there was no significant difference between ADA and TNF-α CONCLUSION: For the differential diagnosis of tuberculous pleural effusion from the other causes of exudative pleural effusions, TNF-α as well as ADA was considered as useful diagnostic method. However adding TNF-α to ADA has no further diagnotic benefit than ADA alone.

OBJECTIVES: There is a controversy on the mechanism of nicotine dependence. Some suggest that the negative reinforcement such as withdrawal symptoms plays an important role, but others suggest that the positive reinforcement through the opioid-dopamine system plays an important role. Under the assumptions that the positive reinforcement and the opioid-dopamine interaction to have an important role in nicotine dependence, this study examined the effects of chronic naltrexone treatment on smoking behaviors, smoking urges to smoking cues and neuroendocrine responses to smoking. METHODS: In a randomized, placebo-control, double-blind design, voluntarily admitted regular smokers who wanted to quit smoking received naltrexone (13 persons) or placebo (12 persons) treatment for 2 weeks. Each week, naltrexone side effects, discomforts after the reduction of cigarette smoking, smoking urges to smoking cues, daily cigarette smoking amount, and expiratory carbon monooxide levels were checked. Also blood beta-endorphin, dynorphin, prolactin, ACTH, and cortisol levels were measured before and after smoking. RESULTS: Naltrexone treatment group showed significantly reduced smoking urges to smoking cues (p=0.036 at 2nd week), daily cigarette smoking amount (p=0.027 at 1st week), and expiratory CO levels (p=0.002 at 1st week, p=0.039 at 2nd week). Naltrexone treatment group also showed significantly increase cortisol level after smoking during the 1st week (p=0.048), and ACTH and prolactin level during the 2nd week (respectively p=0.010, p=0.009). But, the levels of beta-endorphin and dynorphin A were not different between the two groups. Discomfort profiles after the reduction of cigarette smoking, systolic and diastolic BP, and pulse rates were not different between the two groups. CONCLUSION: Longterm naltrexone treatment could be an effective tool used for the cessdtion of smoking. It was suggested that naltrexone blocks the positive reinforcement effects of smoking rather than the negative reinforcement effects of nicotine withdrawal.
