SETTING: Denmark, a country with a low incidence of tuberculosis (TB). OBJECTIVE: To evaluate the value of the nation-wide DNA fingerprinting of Mycobacterium tuberculosis isolates performed in Denmark since 1992. DESIGN: Prospective study of consecutive patients with culture-verified TB from five large TB Departments in Denmark during a 7-month period in 1998. Results of IS6110 RFLP and spoligotyping were compared to those in the nation-wide Danish DNA-fingerprint database which covers approximately 95% of all culture-verified TB cases from 1992 onwards. Questionnaires asking about contact tracing and epidemiological links were sent to the patients' treating physicians. RESULTS: Of the 177 patients included in the study, 57 were Danes, one was from Iceland, 111 were immigrants, and eight were from Greenland. Responses to the questionnaires were obtained from 163 patients (92%). Four cases of unsuspected transmission were detected: one of nosocomial spread of TB, one of occupational acquisition of TB and two of transmission in an international school, leading to further contact tracing among 75 schoolchildren. These four cases were all the result of short-term contacts. In 22 cases, contact with one or more TB patient(s) was reported. In six of these, the DNA-fingerprint result revealed that the presumed contact could not be the source of infection, even though in two of the cases the known TB contact was from the household. CONCLUSION: Nation-wide DNA fingerprinting of TB isolates provides information that could not have been obtained otherwise, and contribute to the understanding of TB transmission in Danish society. In some cases the results lead to further contact tracing. Short-term contact can apparently result in transmission of TB. 相似文献

Salmeterol reduces the need for inhaled corticosteroid in steroid-dependent asthmatics 总被引:1,自引:0,他引:1

Previous results have demonstrated addition of long-acting beta2-adrenergic agonists to be beneficial in asthma patients already receiving inhaled corticosteroid. The purpose of this study was to determine, qualitatively as well as quantitatively, the steroid-sparing properties of salmeterol in stable asthma patients receiving maintenance inhaled corticosteroids (800-1600 microg day(-1)). In these patients, the daily dose of beclomethasone dipropionate was reduced by 200 microg each week until asthma deteriorated, with the minimal acceptable dose (MAD) being defined as the dose one step above deterioration (sensitivity period). Following this, patients received three times the MAD for 2 weeks. Patients were randomized to receive either salmeterol 50 microg twice daily or placebo and the MAD was again determined (treatment period). Forced expiratory volume in 1 sec (FEV1) was measured each week. Morning and evening peak expiratory flow (PEF), symptom score and use of bronchodilator were recorded each day. Fifteen patients received salmeterol and 19 placebo. The MAD was significantly lower in the salmeterol group compared with placebo during the treatment period (P<0.01). A 50% reduction of the MAD was achieved by more patients treated with salmeterol than placebo (P = 0.001). Salmeterol caused a significantly greater reduction in daytime symptom score and use of as-needed beta2-agoinist therapy between sensitivity and treatment periods compared with placebo (P<0.05 for both). The results demonstrate, that the addition of salmeterol to corticosteroid treatment offers a clinically relevant potential for reduction of inhaled corticosteroid dose in steroid sensitive asthmatics. 相似文献

Engel A, Lundberg L, Faarup P, Faurschou P. Histamine-induced bronchoconstriction in conscious guinea pigs measured by strain-gauge transduction. A new method.
A new objective method for measuring histaminedihydrochloride-induced bronchoconstriction in conscious guinea pigs has been developed. The aim of the present work was to investigate whether identical results could be obtained when the clinical observation of conscious guinea pigs with symptoms of respiratory distress (bronchoconstriction) was compared to an objective measuring technique of this parameter. An evaluation of the repeatability of the method was made and the respiration frequence (fR) and histamincdihydrochloride challenge concentration were compared to see whether there was a correlation between the two. Consequently, an appartatus was built that allowed simultaneous recording of breathing pattern and clinical observation of the animal being challenged. The breathing pattern was recorded by a strain-gauge transducer, connected to a measuring bridge, and the curves obtained on a jet ink x-y writer were used for calculating changes in duration of expiratory phase (Te ) and fR. During the attacks of histaminedihydrochloride-induced bronchoconstriction a significantly prolonged Te could be calculated from the respiration curves. A high degree of agreement was found between this objective measure and clinically observed respiratory distress. The repeatability of the method was comparable to that of corresponding methods used for histaminedihydrochloride challenge in man. No obvious correlation was found between changes in fR and histamincdihydrochloride challenge concentration. 相似文献

When turpentine was instilled into the right pleural cavity in rabbits a pleural effusion developed in half of the animals, with a low pH, low glucose concentration, high lactic dehydrogenase activity and the constant presence of rheumatoid arthritis cells in the affected pleural cavity. The biochemical values in the pleural fluid were significantly different from the values for normal pleural fluid obtained by a special microtechnique. These changes resulting from the experimentally induced, simple, irritative turpentine pleuritis are similar to the findings in the pleural effusion in human rheumatoid pleuritis; this implies that such changes are probably non-specific and without evidence of an immunological background. 相似文献

Tumor necrosis factor-alpha (TNF-alpha) is induced by UVB radiation and has been implicated in the early stages of skin carcinogenesis. Here, we show that in normal keratinocytes and the transformed keratinocyte cell lines, HaCaT and A431, TNF-alpha stimulates protein kinase B/Akt, which results in activation of the survival complex mTORC1 (mammalian target of rapamycin complex 1) and inhibition of the proapoptotic proteins Bad and FoxO3a. In UVB-irradiated HaCaT cells (10-20 mJ cm(-2)), TNF-alpha increased the proportion of cycling cells and enhanced the rate of apoptosis. A significantly higher proportion of UVB-treated HaCaT cells containing unrepaired cyclobutane pyrimidine dimers (CPDs) escaped the G2/M cell cycle checkpoint in the presence of TNF-alpha (9.5+/-3.3 vs 4.8+/-2.2%). After treatment with the PI3K inhibitor LY294002, only 1.2+/-0.7% of CPD-containing HaCaT cells were actively cycling. TNF-alpha enhanced apoptosis less potently and did not increase the level of CPD or stimulate cell cycle progression in normal keratinocytes. Our data suggest that TNF-alpha overrides the G2/M checkpoint in premalignant skin cells and allows for some cells containing unrepaired CPD to enter the cell cycle. The effect of TNF-alpha seems to be dependent on Akt activation and may constitute a relevant mechanism enhancing mutagenesis and tumor development. 相似文献

BACKGROUND: It can be difficult to provide patients with idiopathic solar urticaria adequate protection from sunlight. In a nonrandomized controlled trial, we used a standardized phototest procedure to determine the effects of using sunscreen and antihistamine to control idiopathic solar urticaria. OBSERVATIONS: Three patients with idiopathic solar urticaria underwent phototesting with UV-B and UV-A radiation. The minimal urticarial dose (MUD) was determined 15 minutes after irradiation. The patients were subsequently tested with 5 times the MUD, and the reaction was graded every minute for 15 minutes. The patients were then treated with a high-protection, broad-spectrum sunscreen and a nonsedative antihistamine alone and in combination and underwent similar phototesting. The use of sunscreen allowed the patients to tolerate much higher doses of UV radiation (32-38 times the MUD on untreated skin). Antihistamine use did not increase the patients' MUD but did suppress wheal formation and itch, and only immediate erythema sharply located in the irradiated areas occurred. The combination of sunscreen and antihistamine acted synergistically and increased the tolerance to UV radiation markedly (80-267 times the MUD on untreated skin). Conclusion High-protection, broad-spectrum sunscreens and antihistamines protect patients with solar urticaria in different ways and are highly effective when combined. 相似文献

Pleural effusions were made by intrapleural turpentine installation in mice. The fine structure of inflammatory cells from the effusions was normal except for lipid inclusions. The same type of inclusion was previously found in neutrophils from pleural effusions in patients with tuberculous infection, rheumatoid disease, or carcinomatosis. The lipid inclusions observed in neutrophils from an irritative turpentine-induced pleurisy should be considered as "fatty change", and are structurally similar to the rheumatoid arthritis cells seen in patients with different diseases. 相似文献
