The reproductive prognosis of 115 women desiring pregnancy whounderwent surgery for ectopic pregnancy between 1985 and 1990at the Clinica Luigi Mangiagalli, was analysed after a medianfollow-up period of 26 months (range 283). Probabilityof reproductive events was assessed by a product-limit model.Women who underwent surgery for ectopic pregnancy had a 54%probability of becoming pregnant (cumulative pregnancy rate,CPR) and a 36% probability of giving birth to a child (cumulativelivebirth rate, CLB) during the 3 years after surgery. Thesepercentages dropped with history of previous ectopic pregnancy(respectively 33%, P = 0.07, and 7%, P < 0.05). Increasingage at surgery and presence of adhesions in the contra-lateraltube seemed to be associated with poor reproductive prognosis(CPR = 40% and CLB = 12% for women aged 35 years and CPR = 37%and CLB = 20% in women with adhesions in the contra-lateraltube), but these findings were not statistically significant.No association emerged between fertility and parity or typeof surgery. The recurrence rate of ectopic pregnancy was 20%.No significant association emerged between recurrence of ectopicpregnancy and age, history of previous pregnancy, history ofprevious ectopic pregnancy, non-intact contra-lateral tube andsalpingotomy. 相似文献

This study was designed to test the effect of recombinant tissue-type plasminogen activator (rt-PA) in reducing adhesion formation and to observe its influence on peritoneal neoangiogenesis. In 20 Wistar rats, a 4-cm midline incision was made, and a square piece of Silastic, 0.5×0.5 cm and 0.2 mm thick, was fixed on the right side of the peritoneum with two separate angular stitches of nylon 9/O. The rats were randomized into two groups of 10 animals each. In the first group we injected 0.2 mg of rt-PA intraperitoneally three times a day. The second group of 10 rats was used as a control group. Each rat was reoperated on day 12. Intraperitoneal injection of rt-PA seemed not to affect adhesion formation, as a 100% adhesion rate was reported in the treated group compared with 90% of the control group. The results showed that rt-PA acts on the neoangiogenesis involved in postsurgical adhesion formation by reducing the size and length of the vessels. This action seems to slow down peritoneal healing with a negative effect on postsurgical adhesion prevention. 相似文献

Because of the widespread distribution of Mycobacterium intracellulare and M. scrofulaceum in southeastern U.S. waters, the susceptibility of members of these species to heavy-metal salts and oxyanions was investigated. Isolates with abnormally high tolerance to mercuric chloride or cadmium chloride were identified. 相似文献

Phage-typing by itself was not sufficient to delineate the boundaries of a mini-epidemic of tuberculosis in upstate New York. Drug-resistance patterns were needed as well. In a small upstate community, 79% of 14 isolates tested were resistant to one or more of the antituberculosis drugs. Of 15 isolates with phage types determined, 47% were type 1(13), 27% were type 7(7, 13), and 27% were type 1(7, 12, 13). By combining phage-typing and sensitivity testing, we were able to demonstrate that 4 or possibly 5 of the 7 phage-type 1(13) strains are epidemiologically related. 相似文献

The Tween opacity test can be used to differentiate (1) Mycobacterium flavescens from Mycobacterium gordonae and Mycobacterium szulgai, and (2) nonphotochromogenic strains of Mycobacterium kansaii from strains of the Mycobacterium terrae complex. 相似文献

Epidemiology of infection by nontuberculous mycobacteria. IV. Preferential aerosolization of Mycobacterium intracellulare from natural waters 总被引:9,自引:0,他引:9

We report here the first laboratory studies simulating the conditions for natural aerosolization of Mycobacterium intracellulare and M. scrofulaceum and estimate the yields for this pathway of transfer of pathogenic mycobacteria from water to air; M. intracellulare and M. scrofulaceum were both concentrated in droplets ejected from cell suspensions of densities comparable to those found in natural freshwaters (100 to 2,000 colony-forming units per ml). The enrichment factor (defined as the concentration of cells per droplet volume divided by the concentration of cells in the bulk suspension per equivalent volume) for M. intracellulare isolates ranged from 68 to 15,000, with an average of 2,922; for M. scrofulaceum it ranged from 35 to 550, with an average of 177. One factor responsible for the greater aerosolization of M. intracellulare was their aggregation. However, after vortexing, M. intracellulare were still aerosolized more (enrichment factor, 325) than M. scrofulaceum. Increasing salt concentrations enriched the aerosolization of both species, but the number of organisms transferred from water to air did not increase proportionately because the salt decreased the droplet volume. Other waterborne pathogens such as Legionella pneumophila were also enriched and transferred from water to air, indicating that this pathway for possible infection of humans may also be significant for other respiratory diseases. 相似文献

Mycobacteria biochemically and serologically similar to those isolated from humans have been found in estuaries and ocean waters in the south-eastern United States. This is consistent with the hypothesis that aerosols from these waters are one potential source of infection with these mycobacteria. 相似文献
