Several antiseptic and disinfectant compounds have been investigated for their minimal inhibitory concentration (MIC) against antibiotic multiresistant strains of S. wien and S. bredeney as well as S. typhi and S. typhimurium strains characterized by wide spectrum of antibiotic sensitivity. The MICs of AgNO3, merthiolate, NaN3, phenol, Zephiran and Desogen were not substantially different for the former and the latter strains; on the contrary, the HgCl2 minimal inhibitory concentration was significantly higher against S. wien and S. bredeney than against the other strains. The mercury resistance appeared plasmid controlled and transferable to E. coli K-12, always associated with antibiotic resistance. The findings, which confirm the results of other AA., seem unrestrictive of the use of HgCl2, because its not probable selective role in the hospital environment.

To investigate the pathogenic effects of the trypanosome Blastocrithidia triatomae on Triatoma infestans, a method for direct infection by in vitro feeding was developed. After isolation of B. triatomae cysts from infected dead bugs, a suspension of cysts was disinfected with Desogen and Chloramin T, then mixed with sterile blood, spread on a sterile, parallel-grooved glass plate or a hammered aluminium plate and covered with a thin, sterile silicone membrane. The blood and plate were warmed to 36 degrees-38 degrees C by a heating plate. For investigation of the pathological effects, first instars of T. infestans were allowed to feed through the membrane on a mixture containing 10(6) cyst stages/cm3 blood. Development of about 30% of the third and fourth instar larvae was retarded as compared with that in uninfected control groups, and mortality rates increased in fourth and/or fifth instar larvae. Whereas total mortality rates of about 5% occurred in control groups, about 85% of the larvae died in the infected groups. These effects are very similar to those obtained in previous studies with coprophagic infections.

Containers made with PET (Polyethylene-terephthalate) are currently more and more employed in packing industry, particularly for the storage of mineral waters. The increasing utilization of such containers is due to the intrinsic properties of this polymer, which was shown particularly suitable for making bottles devoted to the storage of gassed drinks. The resistance of the PET to high pressure, hits by falls and top-to-down loads indeed makes PET bottles unbreakable; their gas-tightness warrants a good gas maintenance during the storage period; the high transparency of the PET allows a good vision of the contents; the light weight of the bottles and the low temperatures required for their production allow a remarkable saving of energy; lastly PET bottles can easily be recycled. Previous microbiological investigations carried out on several mineral waters bottled in glass bottles and non-PET plastic (i.e. PVC) bottles, had shown higher microbial counts in the water samples stored in plastic bottles. In the present work we have studied the growth rates of the bacterial flora in a sample of non gassed medio-mineral water stored in PET bottles, with respect to a control of the same kind of water, stored in glass bottles. Before using, both PET and glass bottles were washed with 5% Desogen, and sterilized by 100 vol. hydrogen peroxide. After the appropriate sterility checks, the bottles were filled directly from the spring with a non gassed medio-mineral water, and then subdivided into four groups, each consisting of the same number of bottles. A the time of bottling, a bacterial count on such water samples at 20 degrees C and 37 degrees C was performed, in order to establish the "zero" value. One of the two groups of PET bottles, and one of the two groups of glass bottles were stored in the darkness, while the other two groups were stored in the light. Afterwards, one bottle from each group was drawn once a week over one year, in order to measure the bacterial concentration in the water. 20 degrees C and 37 degrees C bacterial counts were done after plating in standard agar. The findings of our study show that the bacterial count in both PET- and glass-stored water increases first, but decreases afterwards, though in a non-uniform rate. Further, light exposure weakly don't affects significantly the bacterial growth, even though, in the average, the bacterial count is lower in the bottles exposed to the light.(ABSTRACT TRUNCATED AT 400 WORDS)

We tried to see whether it was possible to use Bactofen to decontaminate sputum for culture of Mycobacterium tuberculosis. Bactofen showed very little bactericidal action on tubercle bacilli, lower than Desogen, and selectively destroyed many contaminants, more actively than benzalkonium chloride. Digested sputum decontaminated with 0.2% Bactofen and then applied to culture media without centrifugation gave good results in growth of colonies.

The percentages of positive cultures of mycobacteria obtained from sputum, bronchial-aspirate and urine treated with 0.2% Bactofen and with 0.5% Desogen were compared. Respiratory materials gave significantly higher values of these percentages when treated with Bactofen. Urine showed opposite results but these were not statistically significant. Isolates of MOTT too were more frequent in specimens decontaminated with Bactofen. Contamination rate showed no modifications.

Recent advances in contraceptive technology offer US adolescent females the potential to reduce their risk of unwanted pregnancy and sexually transmitted diseases (STDs) without unacceptable side effects. Newly developed oral contraceptives that contain the progestins desogestrel or norgestimate (Desogen, Ortho-Cept, Ortho-Cyclen, and Ortho Tri-Cyclen) have fewer metabolic and androgen-related side effects yet maintain the progestational suppression of ovulation and the endometrium. The failure rate for these progestin pills is under 1%. A Sunday start regimen may be most appropriate for adolescents who have intercourse on weekends. To avoid discontinuation, adolescents should be counseled that breakthrough bleeding may occur for the first three cycles. Also recommended for use by adolescents is the new female condom--the only female-controlled method that confers protection against both pregnancy and STDs. With careful, consistent use, the female condom has a failure rate of 2.6% in the first six months.

Health workers recruited 28 women aged 35-65 attending San Francisco General Hospital in California or Magee-Women's Hospital in Pittsburgh, Pennsylvania, for a prospective study designed to evaluate the laboratory criteria for menopause in women using oral contraceptives (OCs). The first 14 women received three cycles of a triphasic OC containing 35 mcg ethinyl estradiol and 180, 215, and 250 mcg norgestimate (Orth Tri-Cyclen-28). They comprised group 1. The remaining 14 women received three cycles of a monophasic OC containing 30 mcg ethinyl estradiol and 150 mcg desogestrel (Ortho-Cept-28). They comprised group 2. 12 women in each group completed the study. The mid-cycle luteinizing hormone (LH) level was much higher in group 1 than in group 2 (8.8 vs. 3.6 mIU/ml; p = 0.02). The serum follicle stimulating hormone (FSH) level of 62.5% of the women was still less than 30 mIU/ml on day 28 of the third pill package. All the women had an FSH:LH ratio of 1 at baseline and on day 28 of the third OC package, indicative of menopause. This ratio was significantly higher on day 7 of the pill-free interval than at baseline or mid-cycle (2.82 vs. 1.99 and 2.26, respectively; p 0.0001). The proportion of women with estradiol levels of 25 pg/ml was 90% at baseline and in the middle of the third cycle and 95% at the end of the pill-free interval of the third cycle. These findings suggest that the mid-cycle FSH:LH ratio and measuring FSH on the seventh day of the pill-free interval are not reliable indicators of menopause. Instead, a serum FSH:LH ratio of 1 or an estradiol level of 20 pg/ml on the seventh day of the pill-free interval may be a more reliable indicator of menopause in women using OCs in their later reproductive years.

Contraceptive use often leads to disrupted endometrial bleeding patterns in women. In this study, two different contraceptive regimes (Mircette, a monophasic oral contraceptive and Implanon, a long-acting gestagen) were used and their effects on the immunoreactivity of vascular endothelial growth factor (VEGF), oestrogen receptor (ER), progesterone receptor (PR) and endothelial cell number were determined. During the untreated normal cycle, there was a significant increase (P = 0.005) in glandular VEGF immunoreactivity and a significant decrease (P < 0.05) in PR immunoreactivity in the mid- and late secretory phases compared with the proliferative phase. There was a significant positive correlation (gamma = 0.38, P = 0.046) between stromal VEGF immunoreactivity and endothelial cell number. This correlation was also apparent during treatment with Implanon, but not with Mircette. Disrupted bleeding patterns were associated with Implanon and, to a lesser extent, with Mircette. Both contraceptives significantly reduced glandular VEGF immunoreactivity. Implanon significantly increased (P = 0.016) glandular PR staining, but Mircette significantly reduced (P = 0.027) stromal PR staining when compared with secretory before-treatment biopsies. There were no changes in endothelial cell number or glandular or stromal ER during the normal cycle, or with use of either contraceptive. There was no association between the parameters measured with bleeding patterns and histological category.

Estrogen content represents a tradeoff between cycle control and side effects, but few direct comparisons of 20 and 30/35 mcg preparations are available. To address this issue, researchers conducted a randomized, open-label multicenter clinical trial comparing Alesse (20 mcg ethinyl estradiol [EE]), Mircette (20 mcg EE), and Ortho Tri-Cyclen (35 mcg EE) among 463 oral contraceptive starters or switchers. Bloating, breast tenderness, and nausea were approximately 50% more common in women using 35 mcg EE as in those using 20 mcg EE preparations. Cycle control was similar in all products, although during the first two cycles among starters, users of Mircette and Ortho Tri-Cyclen (Tri-Cyclen) exhibited better cycle control than Alesse users. Discontinuation and pregnancy rates were not significantly higher in 35 mcg EE users.

The contraceptive efficacy, cycle control, and safety of a new low-dose, triphasic desogestrel/ethinyl estradiol oral contraceptive (CTR 77, Cyclessa(TM)) was compared to that of a marketed, triphasic norethindrone/ethinyl estradiol oral contraceptive (Ortho-Novum(R) 7/7/7). Two identical multicenter, open-label, randomized, parallel group, comparative Phase III 6-cycle trials were designed to each enroll 4200 healthy women. The combined comparative data for Cyclessa versus Ortho-Novum 7/7/7 for both studies are reported here. Cyclessa and Ortho-Novum 7/7/7 had comparable contraceptive efficacy. Despite a lower ethinyl estradiol dose (25 microg/day vs. 35 microg/day), the Cyclessa group had significantly improved cycle control in comparison to the Ortho-Novum 7/7/7 group for presence of a withdrawal bleed (p = 0.001), lack of early withdrawal bleed (p = 0.01), and breakthrough bleeding/spotting (p = 0.001). For each of the months of the study, the incidence of breakthrough bleeding/spotting was lower in the Cyclessa group than the Ortho-Novum 7/7/7 group (breakthrough bleeding, p = 0.006; breakthrough spotting, p = 0.001). The incidence of other adverse events was similar among treatment groups, an observation that supports the safety of both formulations. There was significantly less weight gain (p = 0.0002) and less increase in the body mass index (BMI) (p = 0.0002) in the Cyclessa group. The contraceptive efficacy and safety of Cyclessa is comparable to Ortho-Novum 7/7/7. Cyclessa provides significantly improved cycle control with no weight gain.
