Sexual function after suburethral sling removal for dyspareunia

INTRODUCTION: Impact on sexual function has received little attention in the medical literature for a long time. Because of the site of insertion of permanent tension free vaginal tape (TVT) the G spot might be affected or the tape might interfere with arousal and sensory stimulation. Recent studies have reported varying degrees of sexual impairment after TVT insertion ranging from 0% to 15% including dyspareunia. AIM: The aim of this study was to evaluate sexual function before and after suburethral sling removal due to postoperative female de novo dyspareunia. As a secondary outcome, general patients' satisfaction with their overall continence situation was assessed. PATIENTS AND METHODS: Between December 2005 and December 2007, we included 18 female patients who complained of de novo dyspareunia after suburethral sling insertion for urinary stress incontinence. All patients filled in an FSFI questionnaire prior to sling removal and at 3 months postoperatively. Additionally, all women were asked to estimate their general satisfaction regarding their continence situation using a Visual Analogue Scale (VAS) from 0 to 10, with 0 being the least satisfying situation and 10 being the most satisfying situation. All patients underwent gynaecological examination including ICS-pelvic organ prolapse staging (ICS-POP score). RESULTS: Of the 18 slings, ten were transobturator tapes (6 x TVT-O, 2 x Monarch, 2 x unknown) and eight were retropubic tapes (7 x TVT, 1 x SPARC). Desire, arousal, lubrication, satisfaction, and pain improved statistically significant. Orgasm scores were low with median scoring of 1.5 scores before and 1.0 scores after sling removal, and they did not change significantly after sling removal. The satisfaction rate deteriorated from a median of 7 (95% confidence interval [CI] 6.3-7.7) to a median of 4 (95% CI 3.7-5.1; p=0.99) but not statistically significant. CONCLUSIONS: Sexual function in patients with de novo dyspareunia is likely to improve after sling removal but not in all domains. Bladder function may deteriorate.

Falkland Island English

This chapter examines some of the grammatical variability and non-standardness found in the English of the Falkland Islands. The Falklands are an archipelago of over 700 islands located in the western South Atlantic Ocean, 480km off the east coast of Argentina. Although the population is small – around 3000 - the islands cover an area of over 12000km2 – slightly larger than Jamaica and half the size of Wales, making them, after Greenland, the most sparsely populated political entity in the world. In political terms, the Falklands are an Overseas Territory of the United Kingdom. In contrast to the rural isolated image that the Falklands perhaps conjure up, the community is, in demographic terms, an urban and diverse one. Over 85% of the population living in the capital Stanley. The 2006 census (Government of the Falkland Islands 2007: 6) shows that 55% of the population were not born on the Islands, with the largest migrant groups coming from the UK, St Helena (another British Overseas Territory, located in the eastern South Atlantic), Chile and Australia. It also highlighted the fact that people born in 62 different countries were resident on the islands at the time (Pascoe and Pepper 2008: 38). By way of a comparison, only Monaco and Andorra, in Europe, have a higher proportion of their populations made up of migrants. In addition to the local Falkland population, there is a large military presence on the islands at the Royal Airforce Base at Mount Pleasant, 50km south-west of Stanley. The Head of State is the monarch of the UK, who is represented on the islands by a governor. The democratically elected 11-member Legislative Assembly is responsible for day-to-day government of the islands. The Falklands are perhaps most famous because of their 74 day occupation by Argentina in 1982. It is not appropriate here to go into detail about the dispute between the UK and Argentina about the sovereignty of the Islands. What is undisputed is that there has been a continuous Anglophone speech community on the islands since the early 1830s, making it one of the most recently developed ‘Inner Circle’ (Kachru 1985) Englishes in the world. This chapter examines the grammatical characteristics of Falkland Island English, drawn from a transcribed corpus of over 500,000 words of informal conversational speech, collected by Andrea Sudbury both in Stanley and in ‘Camp’ (the local name for the rest of the islands) (see Sudbury 2000, 2001 for more details about the methods used in the survey).

The evolution of host associations in the parasitic wasp genus Ichneumon (Hymenoptera: Ichneumonidae): convergent adaptations to host pupation sites

Background: The diversification of organisms with a parasitic lifestyle is often tightly linked to the evolution of their host associations. If a tight host association exists, closely related species tend to attack closely related hosts; host associations are less stable if associations are determined by more plastic traits like parasitoid searching and oviposition behaviour. The pupal-parasitoids of the genus Ichneumon attack a variety of macrolepidopteran hosts.They are either monophagous or polyphagous, and therefore offer a promissing system to investigate the evolution of host associations. Ichneumon was previously divided into two groups based on general body shape; however, a stout shape has been suggested as an adaptation to buried host pupation sites, and might thus not represent a reliable phylogenetic character. Results: We here reconstruct the first molecular phylogeny of the genus Ichneumon using two mitochondrial (CO1 and NADH1) and one nuclear marker (28S). The resulting phylogeny only supports monophyly of Ichneumon when Ichneumon lugens Gravenhorst, 1829 (formerly in Chasmias, stat. rev.) and Ichneumon deliratorius Linnaeus, 1758 (formerly Coelichneumon) are included. Neither parasitoid species that attack hosts belonging to one family nor those attacking butterflies (Rhopalocera) form monophyletic clades. Ancestral state reconstructions suggest multiple transitions between searching for hosts above versus below ground and between a stout versus elongated body shape. A model assuming correlated evolution between the two characters was preferred over independent evolution of host-searching niche and body shape. Conclusions: Host relations, both in terms of phylogeny and ecology, evolved at a high pace in the genus Ichneumon. Numerous switches between hosts of different lepidopteran families have occurred, a pattern that seems to be the rule among idiobiont parasitoids. A stout body and antennal shape in the parasitoid female is confirmed as an ecological adaptation to host pupation sites below ground and has evolved convergently several times. Morphological characters that might be involved in adaptation to hosts should be avoided as diagnostic characters for phylogeny and classification, as they can be expected to show high levels of homoplasy.

Role of Methyl Salicylate on Oviposition Deterrence in Arabidopsis thaliana

Plants attacked by herbivores have evolved different strategies that fend off their enemies. Insect eggs deposited on leaves have been shown to inhibit further oviposition through visual or chemical cues. In some plant species, the volatile methyl salicylate (MeSA) repels gravid insects but whether it plays the same role in the model species Arabidopsis thaliana is currently unknown. Here we showed that Pieris brassicae butterflies laid fewer eggs on Arabidopsis plants that were next to a MeSA dispenser or on plants with constitutively high MeSA emission than on control plants. Surprisingly, the MeSA biosynthesis mutant bsmt1-1 treated with egg extract was still repellent to butterflies when compared to untreated bsmt1-1. Moreover, the expression of BSMT1 was not enhanced by egg extract treatment but was induced by herbivory. Altogether, these results provide evidence that the deterring activity of eggs on gravid butterflies is independent of MeSA emission in Arabidopsis, and that MeSA might rather serve as a deterrent in plants challenged by feeding larvae.

Source Memory for Mental Imagery: Influences of the Stimuli’s Ease of Imagery.

The present study investigated how ease of imagery influences source monitoring accuracy. Two experiments were conducted in order to examine how ease of imagery influences the probability of source confusions of perceived and imagined completions of natural symmetric shapes. The stimuli consisted of binary pictures of natural objects, namely symmetric pictures of birds, butterflies, insects, and leaves. The ease of imagery (indicating the similarity of the sources) and the discriminability (indicating the similarity of the items) of each stimulus were estimated in a pretest and included as predictors of the memory performance for these stimuli. It was found that confusion of the sources becomes more likely when the imagery process was relatively easy. However, if the different processes of source monitoring-item memory, source memory and guessing biases-are disentangled, both experiments support the assumption that the effect of decreased source memory for easily imagined stimuli is due to decision processes and misinformation at retrieval rather than encoding processes and memory retention. The data were modeled with a Bayesian hierarchical implementation of the one high threshold source monitoring model.
