RESUMO

RESULTS: AMH results were pooled and a table with 2.5 and 97.5 percentiles for each age group constructed. Based on Youden index, the optimal cut off for low responders (0-3 eggs), was 5.5 pmol/l (87% sensitivity, 55% specificity) and for high responders (>15 eggs) 15.6 pmol/l (78% sensitivity, 57% specificity). AMH correlated with number of eggs collected (r = 0.48) and clinical pregnancies (r = 0.14), (p < .0001). CONCLUSIONS: The table of AMH levels measured using the Access 2 fully automated immunoassay system according to age may be used as a reference and cutoff levels for high and poor responders are clearly defined to help tailor controlled ovarian stimulation, maximizing efficiency and ensuring patient safety. The use of a random access automated immunoassay system means that blood sampled on arrival can produce an AMH result in 40 mins by the time the subject enters the doctor's clinic together with other relevant endocrine markers.

RESUMO

PURPOSE: Serum anti-Mullerian hormone shows a strong positive correlation to the quantitative ovarian reserve but its correlation to embryo quality is unclear. This study assessed the association between serum AMH as a marker of ovarian reserve and embryo quality, using the technology of time-lapse imaging of the embryos in women undergoing in vitro fertilisation (IVF) treatment. METHODS: 304 embryos from 198 women undergoing IVF were included in the study. Serum AMH was assessed for all women. Embryo quality was assessed with the known implantation data (KID) score generated by the time-lapse imaging system. RESULTS: There was no statistically significant difference in mean serum AMH among different KID score categories (p = 0.135). This remained non-significant after controlling for confounding variables (p = 0.305). CONCLUSIONS: The results of our study show no significant association between serum AMH and embryo quality in women undergoing IVF treatment when embryo quality was assessed using the KID scores generated by time-lapse imaging which is a better method of embryo assessment rather than conventional morphological assessment.

RESUMO

OBJECTIVE: To assess whether ethnic differences in serum anti-Mullerian hormone (AMH) exist in a population of subfertile women presenting to a fertility clinic. DESIGN: Observational cross-sectional study. SETTING: Homerton University Hospital Fertility Centre, London, UK. POPULATION: A total of 865 women attending the fertility clinic for their first consultation appointment between September 2012 and September 2013. METHODS: Serum AMH was compared amongst women from five different ethnic groups. MAIN OUTCOME MEASURES: Serum AMH and ethnicity were the primary outcome variables. RESULTS: Although initial comparison showed South Asian women to have a higher serum AMH, compared with white European and Afro-Caribbean women (F = 3.817; P < 0.005), South Asian women attending the clinic were significantly younger and less likely to be smokers than women from other ethnic groups. The prevalence of polycystic ovary syndrome (PCOS) was significantly higher in South Asian and South East Asian women than in other ethnic groups. Differences in serum AMH were no longer significant after controlling for confounding factors: age, body mass index (BMI), and smoking status with (P = 0.869) and without (P = 0.215) controlling for PCOS. CONCLUSION: The results from our study show that there was no independent association of ethnicity and serum AMH levels in an unselected population of women attending the fertility clinic.

RESUMO

Women's choice to delay fertility due to various reasons is making subfertility a growing problem and increased use of IVF as a last resort. Despite advances in the technology, IVF success remains low, especially in older women. Hence, many of these women need to undergo several cycles of IVF and are faced with unprecedented anxiety and frustration. In desperation, they resort to anything that might increase the success of their IVF treatment. Acupuncture has gained popularity among the various complementary medicines available and many go privately to have acupuncture while undergoing IVF. Since 1999, in spite of multiple trials and systematic reviews, the beneficial effect of acupuncture in improving the success of IVF remains unproven and debatable. As clinicians, we face the dilemma of what to suggest to our patients when asked about having acupuncture during IVF, given that different meta-analyses have come to different conclusions. Hence, this review is conducted with the aim to summarise the available literature and provide a better insight into this complex and controversial topic.

RESUMO

STUDY QUESTION: What is the relationship of serum anti-Mullerian hormone (AMH) with polycystic ovarian morphology (PCOM) and polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: Serum AMH concentrations are capable of differentiating between normal ovaries, PCOM and PCOS. WHAT IS KNOWN ALREADY: Serum AMH levels are high in PCOS reflecting the number of small antral follicles and an intrinsic defect of individual granulosa cells. STUDY DESIGN, SIZE, DURATION: Data were collected prospectively and analysed from three groups of women: those with PCOS according to Rotterdam criteria, those with PCOM but no symptoms and those with normal ovaries. PARTICIPANTS/MATERIAL, SETTING, METHODS: Women with PCOS (n = 90), with PCOM (n = 35) and with normal ovaries (controls, n = 90), matched for age and body mass index, were all being treated for infertility at Homerton University Hospital, a tertiary referral centre. MAIN RESULTS AND THE ROLE OF CHANCE: Using adequate numbers and statistical methods for demographically similar groups, there were significant differences in the mean serum AMH concentrations between women with PCOS [77.6 pmol/l (95% CI 64.8-90.3)], those with PCOM [52.2 pmol/l (95% CI 40.1-64.2)] and controls [23.6 pmol/l (95% CI 20.5-26.7)] (P < 0.001). The combination of AMH >48 pmol/l and LH > 6 IU/l diagnosed 82.6% of women with PCOS. The mean serum FSH was lower in both PCOS and PCOM compared with controls, whereas LH was higher in PCOS compared with PCOM and controls and correlated positively with AMH (r = 0.321, P < 0.01). LIMITATIONS, REASONS FOR CAUTION: Further research is needed to determine the relationship of AMH, PCOS and PCOM. The study was restricted to women who sought out treatment for infertility. WIDER IMPLICATIONS OF THE FINDINGS: The study suggests that the severity of symptoms of PCOS is positively related to the number of small follicles and that AMH may play an important part in the pathophysiology of anovulation. STUDY FUNDING/COMPETING INTEREST: None.

RESUMO

A new stable focus of canine leishmaniasis (CanL) was identified in a coastal Adriatic area of the Emilia-Romagna Region in Northern Italy. Following the first clinical cases observed starting from 1998, a seroepidemiological survey was carried out on owned dogs from two communes and on animals housed in dog pounds of the Rimini province. Sixteen out of 612 dogs (2.6%) resulted positive to the IFA test. The 16 positive dogs all came from the two communes, with seroprevalences of 3 and 6%, respectively. The autochthonous origin of the infection was confirmed in all the cases. The parasitological investigation led to the isolation and identification of the parasite as Leishmania infantum Zymodeme MON 1. An entomological survey showed that Phlebotomus perniciosus and P. perfiliewi are present in this area and that P. perfiliewi was very abundant in one collection site. The risk of the establishment of a permanent transmission of the infection in the area, previously considered CanL-free, must be analysed in view of further investigations to be extended also to neighbouring areas.

RESUMO

Vaginal complaints account for a significant proportion of visits to health care providers and are an ongoing challenge to every clinician in terms of diagnosis and management. Midwives traditionally have viewed such complaints as a disruption of the vaginal ecosystem and have adopted a combination of pharmacologic and nonpharmacologic treatment modalities in the management of vulvovaginitis and sexually transmitted diseases. This article presents a review of the literature that focuses primarily on the pharmacologic management of some of the more common sexually transmitted diseases. The management of vulvovaginal candidiasis and bacterial vaginosis also is reviewed. Although neither condition is sexually transmitted, they always should be considered in the differential diagnosis of vaginal complaints.
