Cervical cerclage in twin pregnancies

Purpose To evaluate the outcomes of cervical cerclage (CC) in twin pregnancies. Methods Retrospective analysis of twin pregnancies undergoing CC between January 2001 and December 2009 at our Institution. CC was offered in case of a cervical length measurement B20 mm (ultrasound-indicated CC) or in case of cervical dilatation with membranes at or beyond the external cervical os (physical examination-indicated CC). Cervicovaginal and rectal swabs were obtained preoperatively. Perioperative antibiotics and tocolysis were administered. Results There were 28 cases of ultrasound-indicated and 14 of physical examination-indicated CC. Positive swab cultures were observed in 21 % of cases. The incidence of preterm delivery\34 weeks was 32 % [95 % confidence interval (CI) 16–52 %] and 50 % (95 % CI 23–77 %) in the ultrasound-indicated and physical examination-indicated CC group, respectively. The incidence of premature rupture of membranes \34 weeks was 21 % (95 % CI 8–41 %) and 29 % (95 % CI 8–58 %) in the ultrasoundindicated and physical examination-indicated CC group, respectively. Perinatal survival was 96 % (95 % CI 88–100 %) in the ultrasound-indicated CC group, and 86 % (95 % CI 67–96 %) in the physical examinationindicated CC group.Conclusions We showed a high-risk of preterm delivery in both groups, but with a high overall perinatal survival. Our data stress the importance of re-evaluating the efficacy of CC in twin pregnancies by properly designed clinical trials, particularly if it is physical examination indicated

Comparison of different primer sets for use in automated ribosomal intergenic spacer analysis of complex bacterial communities

ITSF and ITSReub, constituting a new primer set designed for the amplification of the 16S-23S rRNA intergenic transcribed spacers, have been compared with primer sets consisting of 1406F and 23Sr (M. M. Fisher and E. W. Triplett, Appl. Environ. Microbiol. 65:4630-4636, 1999) and S-D-Bact-1522-b-S-20 and L-D-Bact-132-a-A-18 (L. Ranjard et al., Appl. Environ. Microbiol. 67:4479-4487, 2001), previously proposed for automated ribosomal intergenic spacer analysis (ARISA) of complex bacterial communities. An agricultural soil and a polluted soil, maize silage, goat milk, a small marble sample from the fac\ub8ade of the Certosa of Pavia (Pavia, Italy), and brine from a deep hypersaline anoxic basin in the Mediterranean Sea were analyzed with the three primer sets. The number of peaks in the ARISA profiles, the range of peak size (width of the profile), and the reproducibility of results were used as indices to evaluate the efficiency of the three primer sets. The overall data showed that ITSF and ITSReub generated the most informative (in term of peak number) and reproducible profiles and yielded a wider range of spacer sizes (134 to 1,387) than the other primer sets, which were limited in detecting long fragments. The minimum amount of DNA template and sensitivity in detection of minor DNA populations were evaluated with artificial mixtures of defined bacterial species. ITSF and ITSReub amplified all the bacteria at DNA template concentrations from 280 to 0.14 ng l 1, while the other primer sets failed to detect the spacers of one or more bacterial strains. Although the primer set consisting of ITSF and ITSReub and that of S-D-Bact-1522-b-S-20 and L-D-Bact-132-a-A-18 showed similar sensitivities for the DNA of Allorhizobium undicula mixed with the DNA of other species, the S-D-Bact-1522-b-S-20 and L-D-Bact-132-a-A-18 primer set failed to detect the DNA of Pseudomonas stutzeri

SAT0368 PREGNANCY IN WOMEN WITH SPONDYLOARTHRITIS: WHO ARE THE PATIENTS AT RISK OF DISEASE FLARE?

Background:Patients with Spondyloarthritis (SpA) can experience flares during pregnancy and postpartum even though the available data are limited and not conclusive.Objectives:To assess disease activity and treatment modification during pregnancy and postpartum in patients with SpA and to identify risk factors for disease flare.Methods:Data on SpA pregnancies prospectively-followed in a pregnancy clinic from 2010 to 2019 were retrospectively analysed. Disease activity was assessed during each trimester and postpartum using ASDAS-CRP or DAS28-CRP. Flare was defined as an increase of disease activity leading to treatment modification (introduction or increase ≥5mg/day of prednisone, introduction of cDMARD or bDMARD)1.Results:Data on 50 pregnancies in 46 patients were collected (mean age at conception 33±4.7 years; median disease duration: 60 months (IQR 24-132); 33 psoriatic arthritis, 6 axialSpA, 2 reactive arthritis, 2 IBD-related SpA; 6 undifferentiated SpA, 1 juvenile idiopathic arthritis). Six pregnancies ended in miscarriage, so they weren't considered for the analysis of flares during pregnancy (table 1). Fifteen out of 44 (34%) pregnancies had at least one flare during pregnancy (6, 7 and 4 during 1st, 2ndand 3rdtrimester respectively; 2 pregnancies had multiple flares). A higher rate of flare was observed in pregnancies of patients with axial involvement (p=0.01), on treatment with bDMARDs at preconceptional visit (p=0.03) and who stopped TNFi at positive pregnancy test (p=0.03). Peripheral involvement was associated with a lower rate of flares (p=0.02). Medications resumed during pregnancy were steroids (in 6 pregnancies), cDMARDs (2 sulfasalazine, 1 cyclosporine) and bDMARDs (4 certolizumab, 4 etanercept). During postpartum period flares were recorded in 46% of patients.Table 1.clinical features, medication and disease activity in pregnancies with flare vs without flareCLINICAL FEATURESFLARE (15)NO FLARE (29)pAxial involvement, n (%)11/15 (73)9/29 (31)0.01Peripheral arthritis, n (%)8/15 (53)26/29 (90)0.02Enthesitis, n (%)5/15 (33)14/29 (48)nsDactilitis, n (%)3/15 (20)8/29 (28)nsPsoriasis, n (%)6/15 (40)17/29 (59)nsIBD, n (%)2/15 (13)0nsUveitis, n(%)1/15 (7)3/29 (10)nsHLAB27 +7/11 (64)5/12 (42)nsMEDICATION HISTORYbDMARDs, n (%)11/15 (73)7/29 (24)0.003bDMARDs at preconception visit, n (%)8/15 (53)6/29 (21)0.04bDMARDs stopped at positive pregnancy test, n (%)7/15 (47)4/29 (14)0.03cDMARDs, n (%)12/15 (80)25/29 (86)nsDISEASE ACTIVITYACTIVE DISEASE* preconception visit, n(%)3/14 (21)4/23 (17)nsACTIVE DISEASE 1sttrimester, n(%)6/15 (40)1/29 (3)0.004ACTIVE DISEASE 2ndtrimester, n(%)8/15 (47)2/29 (7)0.001ACTIVE DISEASE 3rdtrimester, n(%)2/15 (13)1/29 (3)ns*DAS28-CRP>3.2 or ASDAS-CRP≥2.1Conclusion:In our cohort of prospectively-followed SpA pregnancies, 34% experienced a flare during pregnancy and 46% during postpartum. Flares occurred especially in those patients who discontinued TNFi early in pregnancy and with axial involvement. When resumed during pregnancy, TNFi was able to control the disease. At preconception counselling, the continuation of TNFi during pregnancy should be considered to ensure a better control of disease.References:[1]Fischer-Betz R et al.Arthritis Rheumatol. 2015; 67.Disclosure of Interests: :None declare

Assessment of the effect of phenytoin on cutaneous healing from excision of melanocytic nevi on the face and on the back

<p>Abstract</p> <p>Background</p> <p>Topical phenytoin is a powerful skin wounds healing and it may be useful in clinical practice. The purpose of this study was to evaluate the effect of topical phenytoin 0.5%, by comparing it with cream (control) in wounds resulting from excision of two melanocytic nevi in the same patient. Our purpose was also to assess if phenytoin had better therapeutic and cosmetic outcomes when compared with cream (control).</p> <p>Methods</p> <p>This study evaluated 100 patients with skin wounds from excision of melanocytic nevi. 50 patients with lesions on the face and 50 patients with lesions on the back, totalizing 200 lesions excised with modified punch. The resulting superficial skin wounds had the same diameter and depth, and second intention healing followed.</p> <p>Patients were followed for 60 days. Student's t-test, Mann Whitney nonparametric test, analysis of variance, LSD test, Shapiro-Wilks test and Fisher test were used to analyze the results, depending on the nature of the variables being studied.</p> <p>Results</p> <p>Phenytoin showed better therapeutic and cosmetic results, by healing faster, with more intense epithelization in wounds in comparison with cream (control). Phenytoin showed a statistically significant difference regarding the following parameters (p < 0.05): wounded area and healing time. Phenytoin application resulted in a smaller area and a shorter healing time. Also the intensity of exudates, bleeding, and the epithelization were more intense in phenytoin-treated wounds. Regarding the shape and thickness of the scar, injuries treated with phenytoin had round and flat shaped scars in most of the cases. Considering patient's gender and phototype, female patients presented smaller wounds and scar areas; and phototype I had the largest scar areas. Contact eczema was an adverse reaction in 7 injuries located on the back caused by cream (control) and hypoallergenic tape.</p> <p>Conclusions</p> <p>Phenytoin showed better therapeutic and cosmetic results compared with cream (control). Phenytoin is a low cost drug, which accelerates skin wounds healing in human patients. Trial registration: ISRCTN96539803</p

Molecular Tools for Monitoring the Ecological Sustainability of a Stone Bio-Consolidation Treatment at the Royal Chapel, Granada

Background: Biomineralization processes have recently been applied in situ to protect and consolidate decayed ornamental stone of the Royal Chapel in Granada (Spain). While this promising method has demonstrated its efficacy regarding strengthening of the stone, little is known about its ecological sustainability.Methodology/Principal Findings: Here, we report molecular monitoring of the stone-autochthonous microbiota before and at 5, 12 and 30 months after the bio-consolidation treatment (medium/long-term monitoring), employing the well-known molecular strategy of DGGE analyses. Before the bio-consolidation treatment, the bacterial diversity showed the exclusive dominance of Actinobacteria (100%), which decreased in the community (44.2%) after 5 months, and Gamma-proteobacteria (30.24%) and Chloroflexi (25.56%) appeared. After 12 months, Gamma-proteobacteria vanished from the community and Cyanobacteria (22.1%) appeared and remained dominant after thirty months, when the microbiota consisted of Actinobacteria (42.2%) and Cyanobacteria (57.8%) only. Fungal diversity showed that the Ascomycota phylum was dominant before treatment (100%), while, after five months, Basidiomycota (6.38%) appeared on the stone, and vanished again after twelve months. Thirty months after the treatment, the fungal population started to stabilize and Ascomycota dominated on the stone (83.33%) once again. Members of green algae (Chlorophyta, Viridiplantae) appeared on the stone at 5, 12 and 30 months after the treatment and accounted for 4.25%, 84.77% and 16.77%, respectively.Conclusions: The results clearly show that, although a temporary shift in the bacterial and fungal diversity was observed during the first five months, most probably promoted by the application of the bio-consolidation treatment, the microbiota tends to regain its initial stability in a few months. Thus, the treatment does not seem to have any negative side effects on the stone-autochthonous microbiota over that time. The molecular strategy employed here is suggested as an efficient monitoring tool to assess the impact on the stone-autochthonous microbiota of the application of biomineralization processes as a restoration/conservation procedure.This work was supported by the European Regional Development Fund (ERDF), Junta de Andalucía (Spain) and the “Fortalecimiento de la I+D+i” program from the University of Granada, co-financed by grant RNM-3493 and Research Group BIO-103 from Junta de Andalucía, as well as by the Spanish Government through “José Castillejo” program from the “Ministerio de Educación, Cultura y Deporte” (I+D+i 2008-2011), and by the Austrian Science Fund (FWF) under Grant “Elise-Richter V194-B20”

The status of Agardhiella tenera and Agardhiella baileyi (Rhodophyta, Gigartinales)

Evidence is presented to support the placement of Agardhiella tenera in Solieria (as S. tenera comb. nov.) for the reason that a large fusion cell is present in the center of the cystocarp. Since A. tenera is the type species of the genus, Agardhiella S chmitz (1896) becomes a junior synonym of Solieria J. A gardh (1842). It is argued that A. baileyi , upon which the generic description of Agardhiella was based, is generically distinct from Solieria , and Neoagardhiella gen. nov. is proposed, with N. baileyi as the type species. Agardhiella ramosissima is also transferred into this new genus. The old observations of Solieria as a procarpial genus made by B ornet & T huret (1880) are reinforced by the present observations. This situation in the type genus of the family is contrasted with the nonprocarpial condition known in several other genera at present considered members of the Solieriaceae.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42895/1/10750_2004_Article_BF00014259.pd
