Abstract
OBJECTIVE To assess the costs and benefits of two algorithms for cervical cancer screening in Belgium (1) high-risk human papillomavirus (HR-HPV) primary screening and (2) HR-HPV and liquid-based cytology (LBC) co-testing. METHODS A decision tree was adapted from published work and parameterised using HORIZON study data and Belgian cost and population data. The theoretical model represents two different screening algorithms for a cohort of 577 846 women aged 25-64 attending routine cervical screening. Scenario analyses were used to explore the impact of including vaccinated women and alternative pricing approaches. Uncertainty analyses were conducted. RESULTS The cost per woman screened was €113.50 for HR-HPV primary screening and €101.70 for co-testing, representing a total cost of €65 588 573 and €58 775 083, respectively, for the cohort; a 10% difference. For one screening cycle, compared to HR-HPV primary, co-testing resulted in 13 173 more colposcopies, 67 731 more HR-HPV tests and 477 020 more LBC tests. Co-testing identified 2351 more CIN2+ cases per year (27% more than HR-HPV primary) and 1602 more CIN3+ cases (24% more than HR-HPV primary) than HR-HPV primary. CONCLUSION In Belgium, a co-testing algorithm could increase cervical pre-cancer detection rates compared to HR-HPV primary. Co-testing would cost less than HR-HPV primary if the cost of the HPV test and LBC were cost-neutral compared to the current cost of LBC screening but would cost more if the cost per HPV test and LBC were the same in both co-testing and HR-HPV primary strategies.

Abstract
STUDY QUESTION How do plasma progesterone (P) and dydrogesterone (D) concentrations together with endometrial histology, transcriptomic signatures, and immune cell composition differ when oral dydrogesterone (O-DYD) or micronized vaginal progesterone (MVP) is used for luteal phase support (LPS)? SUMMARY ANSWER Although after O-DYD intake, even at steady-state, plasma D and 20αdihydrodydrogesterone (DHD) concentrations spiked in comparison to P concentrations, a similar endometrial signature was observed by histological and transcriptomic analysis of the endometrium. WHAT IS KNOWN ALREADY O-DYD for LPS has been proven to be noninferior compared to MVP in two phase III randomized controlled trials. Additionally, a combined individual participant data and aggregate data meta-analysis indicated that a higher pregnancy rate and live birth rate may be obtained in women receiving O-DYD versus MVP for LPS in fresh IVF/ICSI cycles. Little data are available on the pharmacokinetic (PK) profiles of O-DYD versus MVP and their potential molecular differences at the level of the reproductive organs, particularly at the endometrial level. STUDY DESIGN, SIZE, DURATION Thirty oocyte donors were planned to undergo two ovarian stimulation (OS) cycles with dual triggering (1.000 IU hCG + 0.2 mg triptorelin), each followed by 1 week of LPS: O-DYD or MVP, in a randomized, cross-over, double-blind, double-dummy fashion. On both the first and eighth days of LPS, serial blood samples upon first dosing were harvested for plasma D, DHD, and P concentration analyses. On Day 8 of LPS, an endometrial biopsy was collected for histologic examination, transcriptomics, and immune cell analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS All oocyte donors were <35 years old, had regular menstrual cycles, no intrauterine contraceptive device, anti-Müllerian hormone within normal range and a BMI ≤29 kg/m2. OS was performed on a GnRH antagonist protocol followed by dual triggering (1.000 IU hCG + 0.2 mg triptorelin) as soon as ≥3 follicles of 20 mm were present. Following oocyte retrieval, subjects initiated LPS consisting of MVP 200 mg or O-DYD 10 mg, both three times daily. D, DHD, and P plasma levels were measured using liquid chromatography-tandem mass spectrometry. Histological assessment was carried out using the Noyes criteria. Endometrial RNA-sequencing was performed for individual biopsies and differential gene expression was analyzed. Endometrial single-cell suspensions were created followed by flow cytometry for immune cell typing. MAIN RESULTS AND THE ROLE OF CHANCE A total of 21 women completed the entire study protocol. Subjects and stimulation characteristics were found to be similar between groups. Following the first dose of O-DYD, the average observed maximal plasma concentrations (Cmax) for D and DHD were 2.9 and 77 ng/ml, respectively. The Cmax for D and DHD was reached after 1.5 and 1.6 h (=Tmax), respectively. On the eighth day of LPS, the first administration of that day gave rise to a Cmax of 3.6 and 88 ng/ml for D and DHD, respectively. For both, the observed Tmax was 1.5 h. Following the first dose of MVP, the Cmax for P was 16 ng/ml with a Tmax of 4.2 h. On the eighth day of LPS, the first administration of that day showed a Cmax for P of 21 ng/ml with a Tmax of 7.3 h. All 42 biopsies showed endometrium in the secretory phase. The mean cycle day was 23.9 (±1.2) in the O-DYD group versus 24.0 (±1.3) in the MVP group. RNA-sequencing did not reveal significantly differentially expressed genes between samples of both study groups. The average Euclidean distance between samples following O-DYD was significantly lower than following MVP (respectively 12.1 versus 18.8, Mann-Whitney P = 6.98e-14). Immune cell profiling showed a decrease of CD3 T-cell, γδ T-cell, and B-cell frequencies after MVP treatment compared to O-DYD, while the frequency of natural killer (NK) cells was significantly increased. LIMITATIONS, REASONS FOR CAUTION The main reason for caution is the small sample size, given the basic research nature of the project. The plasma concentrations are best estimates as this was not a formal PK study. Whole tissue bulk RNA-sequencing has been performed not correcting for bias caused by different tissue compositions across biopsies. WIDER IMPLICATIONS OF THE FINDINGS This is the first study comparing O-DYD/MVP, head-to-head, in a randomized design on a molecular level in IVF/ICSI. Plasma serum concentrations suggest that administration frequency is important, in addition to dose, specifically for O-DYD showing a rapid clearance. The molecular endometrial data are overall comparable and thus support the previously reported noninferior reproductive outcomes for O-DYD as compared to MVP. Further research is needed to explore the smaller intersample distance following O-DYD and the subtle changes detected in endometrial immune cells.

Abstract
Abstract
Background
Black pigmentation of the aortic valve and coronary arteries has been reported to be caused by alkaptonuria or minocycline. In patients with liver transplantation it has been described only once, after exposure to minocycline. We report a second case of such pigmentation in a liver transplantation patient, for whom none of the known causes are an adequate explanation for this pigmentation.
Case presentation
Our 56-year-old male patient showed a complex history of two liver transplantations and sleeve gastrectomy, and had neither alkaptonuria nor a history of minocycline intake. He underwent an urgent coronary bypass grafting and aortic valve replacement because of an acute coronary syndrome based on three-vessel disease and progressive aortic valve stenosis. During this procedure, the aortic valve and coronary arteries had black pigmentation.
Conclusions
There are causes – other than alkaptonuria and minocycline – that can induce a black pigmentation of the aortic valve and coronary arteries. In patients with a history of liver transplantation, alteration in (dys)functional liver parenchyma or administration of substances related to the procedure of liver transplantation are possible causes. Identifying these is important because they are potentially harmful as they may induce degenerative changes and functional impairment of the aortic valve and coronary arteries. Further research is needed, but proves to be difficult due to the rare nature of this condition.

Abstract
BACKGROUND High-risk human papilloma virus (HR HPV) testing and liquid-based cytology are used for primary cervical screening. Digital cytology, based on whole-slide scanned samples, is a promising technique for teaching and diagnostic purposes. The aim of our study was to evaluate the interobserver and intraobserver variation in low-grade squamous lesions, HR HPV status bias, and the use of whole-slide scanned digital cervical cytology slides. METHODS Fifteen expert cytopathologists evaluated 71 digitalized ThinPrep slides (31 atypical squamous cells of undetermined significance [ASC-US], 21 negative for intraepithelial lesion or malignancy, and 19 low-grade squamous intraepithelial lesion cases). HR HPV data were accessible only in the second round. RESULTS In interobserver analysis, Kendall's coefficient of concordance was 0.52 in the first round and 0.58 in the second round. Fleiss' kappa values were 0.29 in the first round and 0.31 in the second round. In the ASC-US category, Fleiss kappa increased from 0.19 to 0.22 in the second round and the increase was even higher expressed by Kendall's coefficient: from 0.42 to 0.52. In intraobserver analysis, personal scores were higher in the second round. CONCLUSIONS The interobserver and intraobserver variability in low-grade squamous lesions was within fair agreement values in the present study, in line with previous works. The comparison of two rounds showed that expert cytopathologists are generally unbiased by the knowledge of HR HPV data, but that being informed of the HR HPV status leads to a better agreement. Stain quality and back discomfort were highlighted as factors affecting digital cytopathology use.

Abstract
Background: Empirical treatment of Helicobacter pylori (HP) depends on the local prevalence of clarithromycin resistance but data are lacking and culturing of HP is time-consuming. We evaluated RIDA®GENE Helicobacter pylori assay (r-biopharm), a quantitative PCR assay for detecting HP and clarithromycin resistance mutations in gastric biopsies.Material/methods: Gastric biopsies were obtained from each of 436 consecutive patients referred for gastroscopic investigation and results of qPCR were compared to culture and immunohistochemical staining (IHCS).Results: Of 436 samples, 47 were positive for HP by PCR (11%), 42 by culture (9.7%) and 44 by IHCS (10%). Compared to culture, sensitivity and specificity of the qPCR were 100% and 99%, respectively, and 96% and 99% compared to IHCS. The sensitivity and specificity for clarithromycin resistance detection were 92% and 97%, respectively.Conclusions: RIDA®GENE Helicobacter pylori assay reliably and rapidly detects HP and its resistance to clarithromycin in human gastric biopsies.

Abstract
STUDY QUESTION Does an early proliferative phase endometrial biopsy harvested during ovarian stimulation harbour information predictive of the outcome following fresh embryo transfer (ET) in that same cycle? SUMMARY ANSWER Transcriptome analysis of the whole-tissue endometrium did not reveal significant differential gene expression (DGE) in relation to the outcome; however, the secretome profile of isolated, cultured and in vitro decidualized endometrial stromal cells (EnSCs) varied significantly between patients who had a live birth compared to those with an implantation failure following fresh ET in the same cycle as the biopsy. WHAT IS KNOWN ALREADY In the majority of endometrial receptivity research protocols, biopsies are harvested during the window of implantation (WOI). This, however, precludes ET in that same cycle, which is preferable as the endometrium has been shown to adapt over time. Endometrial biopsies taken during ovarian stimulation have been reported not to harm the chances of implantation, and in such biopsies DGE has been observed between women who achieve pregnancy versus those who do not. The impact of the endometrial proliferative phase on human embryo implantation remains unclear, but deserves further attention, especially since in luteal phase endometrial biopsies, a transcriptional signature predictive for repeated implantation failure has been associated with reduced cell proliferation, possibly indicating proliferative phase involvement. Isolation, culture and in vitro decidualization (IVD) of EnSCs is a frequently applied basic research technique to assess endometrial functioning, and a disordered EnSC secretome has previously been linked with failed implantation. STUDY DESIGN, SIZE, DURATION This study was nested in a randomized controlled trial (RCT) investigating the effect of endometrial scratching during the early follicular phase of ovarian stimulation on clinical pregnancy rates after IVF/ICSI. Of the 96 endometrial biopsies available, after eliminating those without fresh ET and after extensive matching in order to minimize the risk of potential confounding, 18 samples were retained to study two clinical groups: nine biopsies of patients with a live birth versus nine biopsies of patients with an implantation failure, both following fresh ET performed in the same cycle as the biopsy. We studied the proliferative endometrium by analysing its transcriptome and by isolating, culturing and decidualizing EnSCs in vitro. We applied this latter technique for the first time on proliferative endometrial biopsies obtained during ovarian stimulation for in-cycle outcome prediction, in an attempt to overcome inter-cycle variability. PARTICIPANTS/MATERIALS, SETTING, METHODS RNA-sequencing was performed for 18 individual whole-tissue endometrial biopsies on an Illumina HiSeq1500 machine. DGE was analysed three times using different approaches (DESeq2, EdgeR and the Wilcoxon rank-sum test, all in R). EnSC isolation and IVD was performed (for 2 and 4 days) for a subset of nine samples, after which media from undifferentiated and decidualized cultures were harvested, stored at -80°C and later assayed for 45 cytokines using a multiplex suspension bead immunoassay. The analysis was performed by partial least squares regression modelling. MAIN RESULTS AND THE ROLE OF CHANCE After correction for multiple hypothesis testing, DGE analysis revealed no significant differences between endometrial samples from patients who had a live birth and those with an implantation failure following fresh ET. However secretome analysis after EnSC isolation and culture, showed two distinct clusters that clearly corresponded to the two clinical groups. Upon IVD, the secretome profiles shifted from that of undifferentiated cells but the difference between the two clinical groups remained yet were muted, suggesting convergence of cytokine profiles after decidualization. LIMITATIONS, REASONS FOR CAUTION Caution is warranted due to the limited sample size of the study and the in vitro nature of the EnSC experiment. Validation on a larger scale is necessary, however, hard to fulfil given the very limited availability of in-cycle proliferative endometrial biopsies outside a RCT setting. WIDER IMPLICATIONS OF THE FINDINGS These data support the hypothesis that the endometrium should be assessed not only during the WOI and that certain endometrial dysfunctionalities can probably be detected early in a cycle by making use of the proliferative phase. This insight opens new horizons for the development of endometrial tests, whether diagnostic or predictive of IVF/ICSI treatment outcome.

Abstract
OBJECTIVE Papillary renal cell carcinoma (papRCC) is a rare (10%-15%) subtype of renal cancer. Few prognostic biomarkers have been described in metastatic papRCC (m-papRCC) patients treated with vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs). We aimed to study the prognostic impact of bone metastases (BM) on response rate, progression-free and overall survival (PFS and OS) in patients with m-papRCC treated with first agent VEGFR-TKIs. PATIENTS AND METHODS A multicentric, retrospective analysis of patient records was conducted. BM were detected by computed tomography and/or bone scintigraphy. The International Metastatic RCC Database Consortium (IMDC) score was calculated at start of first agent VEGFR-TKI treatment. RESULTS Forty-nine patients were included. Best objective response was partial response in 20%, stable disease in 60% and early progressive disease in 20% of patients. Median PFS (mPFS) was 6.0 months and median OS (mOS) 14.0 months after start of first agent VEGFR-TKI. The IMDC score correlated with mOS: 77.5 months in good, 17.0 months in intermediate and 8.0 months in poor risk patients (P = 0.002). Patients with BM had a poorer outcome compared to patients without BM: mPFS was 4.0 vs. 7.0 months (P = 0.006) and mOS 7.5 vs. 19.0 months (P = 0.002). On bivariate analysis, the presence of BM was independently associated with PFS (P = 0.02) and OS (P = 0.049), independent of the IMDC risk groups. CONCLUSION In m-papRCC patients treated with first agent VEGFR-TKIs, the presence of BM is an unfavorable prognostic factor, associated with shorter PFS and OS.

Abstract
Clinical outcomes of fresh embryo transfer in non-hCG triggered in vitro maturation (IVM) cycles are inferior compared to vitrified-warmed embryo transfer. This is a prospective observational pilot study in a consecutive cohort of 31 polycystic ovary syndrome (PCOS) patients and 37 normo-ovulatory egg donors who underwent IVM without fresh embryo transfer between July 2009 and June 2014. All subjects received 150 IU of highly purified menotropin (HP-hMG) daily for three days. On cycle day 6, all patients started transdermal oestradiol (E2) at a daily dose of 9 mg. There was no human chorionic gonadotropin (hCG) trigger before oocyte retrieval (OR). Vaginal micronized progesterone was commenced on the evening after OR, at a daily dose of 600 mg. Additional luteal phase support (LPS) was administered as follows: Group A: no additional LPS; Group B: 1500 IU of hCG administered 4 h after OR and Group C: 5000 IU of hCG administered 4 h after OR + an additional injection of 5000 IU of hCG 1 day before endometrial biopsy. Endometrial biopsy for histology and immunohistochemistry (IHC) was performed on day 5 or 6 after OR. Instead of being downregulated, both PR-B and ERα in endometrial glands and stroma were moderately to strongly expressed in all three protocols, suggesting that the mid-luteal histological signature of endometrial receptivity is deficient in a non-hCG-triggered IVM cycle. Poor clinical outcomes after fresh embryo transfer following IVM are probably related to inappropriate endometrial development which may be linked to the short follicular phase of IVM cycles.

Abstract
BACKGROUND The most frequent metastases to the thyroid originate in the kidney, lung or breast. Colorectal adenocarcinoma represents less than 4% of metastases to the thyroid gland. Solitary metastases of colorectal cancer with no other manifestation of disseminated cancer disease are exceedingly rare. Within the Bethesda Classification for Reporting -Thyroid Cytopathology, metastases are included in Diagnostic Categories "Suspicious for Malignancy" and "Malignant." CASES We present 2 cases of colorectal adenocarcinoma metastatic to the thyroid gland, diagnosed by fine-needle aspiration (FNA). One metastasis occurred in normal thyroid parenchyma; the other was a tumour-to-tumour metastasis into a follicular carcinoma of the thyroid. The latter is the first published tumour-to-tumour metastasis of a colorectal carcinoma in the thyroid from which both components were diagnosed by FNA. CONCLUSION Diagnosing a metastasis to the thyroid is challenging. On FNA, a dual cell population should raise suspicion. Immunocytochemical and molecular analysis may be helpful. Clinical information is essential in guiding specific ancillary technique panels in scant cellular material.

Abstract
Cervical intra-epithelial neoplasia is a very common and well-known pathology. However superficial spreading of this lesion is very rare. The authors present a case of a 72-year-old woman with an abdominal mass, who had previously undergone a cervical conisation for a high-grade cervical intra-epithelial neoplasia. Anatomo-pathological examination of the mass showed a large distended fluid-filled uterus with the entire endometrium replaced by a high-grade squamous cell lesion. There were only micro-invasive foci found. The authors performed a literature search in PubMed with the following MeSH-terms: "squamous cell carcinoma" and "endometrium". Other articles were selected out of the references of previously found articles. Only 31 similar cases were found. The presentation of the cases is varies extremely and a long-term prognosis is not yet known.

Abstract
The advent of BRAF-targeted therapies led to increased survival in patients with metastatic melanomas harboring a BRAF V600 mutation (implicated in 46-48% of malignant melanomas). The Idylla(™) System (Idylla(™)), i.e., the real-time-PCR-based Idylla(™) BRAF Mutation Test performed on the fully-automated Idylla(™) platform, enables detection of the most frequent BRAF V600 mutations (V600E/E2/D, V600K/R/M) in tumor material within approximately 90 min and with 1% detection limit. Idylla(™) performance was determined in a multi-center study by analyzing BRAF mutational status of 148 archival formalin-fixed paraffin-embedded (FFPE) tumor samples from malignant melanoma patients, and comparing Idylla(™) results with assessments made by commercial or in-house routine diagnostic methods. Of the 148 samples analyzed, Idylla(™) initially recorded 7 insufficient DNA input calls and 15 results discordant with routine method results. Further analysis learned that the quality of 8 samples was insufficient for Idylla(™) testing, 1 sample had an invalid routine test result, and Idylla(™) results were confirmed in 10 samples. Hence, Idylla(™) identified all mutations present, including 7 not identified by routine methods. Idylla(™) enables fully automated BRAF V600 testing directly on FFPE tumor tissue with increased sensitivity, ease-of-use, and much shorter turnaround time compared to existing diagnostic tests, making it a tool for rapid, simple and highly reliable analysis of therapeutically relevant BRAF mutations, in particular for diagnostic units without molecular expertise and infrastructure.

Abstract
OBJECTIVE To study the efficacy of a new P preparation in aqueous solution for subcutaneous injection for inducing the predecidual transformation of the endometrium. DESIGN Prospective, single-blinded, randomized, parallel pilot trial. SETTING University-affiliated clinical research center. PATIENT(S) Twenty-five regularly cycling female volunteers. INTERVENTION(S) Volunteers, aged 18-45 years, body mass index 19-25 kg/m(2), whose ovaries were suppressed with a GnRH agonist were estrogenized for 14 or 21 days with the use of transdermal systems delivering 0.1 mg/d E₂. After confirming that the endometrial thickness was >7 mm, the women were randomized to 25 mg or 50 mg of subcutaneous P injections daily for 11 days, after which the endometrium was sampled with the use of a Pipelle device. The endometrial biopsies were evaluated by two independent pathologists. Adverse events and subjective tolerance were checked every day by the study investigator. MAIN OUTCOME MEASURE(S) Predecidual changes in endometrial biopsies obtained after 11 days of subcutaneous administration of P. RESULT(S) Of 24 biopsies performed (one dropout), 22 provided tissue for histologic analysis. Evidence of predecidual changes in the endometrial stroma was found in 100% of the cases, with no differences between the two studied doses. CONCLUSION(S) Both doses of the new aqueous P preparation available for subcutaneous administration demonstrated predecidual changes in 100% of the interpretable endometrial biopsies in total absence of endogenous P. This offers good prospect of efficacy in luteal phase support for the lowest dose tested, 25 mg/d, the physiologic amount produced daily by the ovary during the midluteal phase. CLINICAL TRIAL REGISTRATION NUMBER NCT00377923.

Abstract
Leydig cell hyperplasia and Leydig cell tumours of the ovary are rare. We present two cases in which patients had increased blood levels of testosterone and frank hirsutism. Imaging showed minimal abnormalities. After adrenal disease had been ruled out, they underwent a bilateral oophorectomy. One case showed a Leydig cell hyperplasia, the other a Leydig cell tumour. An androgen producing tumour should be excluded in every woman with evidence of hirsutism or frank virilization and markedly elevated testosterone levels. Adrenal disease with androgen hypersecretion can be suspected by detailed clinical, laboratory and radiologic imaging. Although DHEAS has a good sensitivity in the detection of adrenal origin of hyperandrogenism (and hence a good negative predictive value) it is not specific (specificity ranging from 85 to 98%). Imaging of the ovaries can be helpful but does not rule out ovarian disease if normal. Indeed, diffuse stromal Leydig cell hyperplasia and Leydig cell tumours (usually small) may escape imaging and in some cases diagnosis can only be made on pathology. As these clinical entities represent a diagnostic and therapeutic challenge, oophorectomy should be considered in postmenopausal women with hirsutism and elevated testosterone levels, after the exclusion of adrenal causes. The procedure is relatively safe and effective. Follow-up remains indicated.

Abstract
STUDY QUESTION Do differences in endometrial gene expression exist after ovarian stimulation with four different regimens of triggering final oocyte maturation and luteal phase support in the same patient? SUMMARY ANSWER Significant differences in the expression of genes involved in receptivity and early implantation were seen between the four protocols. WHAT IS KNOWN ALREADY GnRH agonist triggering is an alternative to hCG triggering in GnRH antagonist co-treated cycles, resulting in an elimination of early ovarian hyperstimulation syndrome. Whereas previous studies have revealed a low ongoing clinical pregnancy rate after GnRH agonist trigger due to a high early pregnancy loss rate, despite supplementation with the standard luteal phase support, more recent studies, employing a 'modified' luteal phase support including a bolus of 1500 IU hCG on the day of oocyte aspiration, have reported ongoing pregnancy rates similar to those seen after hCG triggering. STUDY DESIGN, SIZE DURATION A prospective randomized study was performed in four oocyte donors recruited from an oocyte donation program during the period 2010-2011. PARTICIPANTS, MATERIALS, SETTING, METHODS Four oocyte donors in a university IVF center each prospectively underwent four consecutive stimulation protocols, with different modes of triggering final oocyte maturation and a different luteal phase support, followed by endometrial biopsy on Day 5 after oocyte retrieval. The following protocols were used: (A) 10 000 IU hCG and standard luteal phase support, (B) GnRH agonist (triptorelin 0.2 mg), followed by 1500 IU hCG 35 h after triggering final oocyte maturation, and standard luteal phase support, (C) GnRH agonist (triptorelin 0.2 mg) and standard luteal phase support and (D) GnRH agonist (triptorelin 0.2 mg) without luteal phase support. Microarray data analysis was performed with GeneSpring GX 11.5 (RMA algorithm). Pathway and network analysis was performed with the gene ontology software Ingenuity Pathways Analysis (Ingenuity® Systems, www.ingenuity.com, Redwood City, CA, USA). Samples were grouped and background intensity values were removed (cutoff at the lowest 20th percentile). A one-way ANOVA test (P< 0.05) was performed with Benjamini-Hochberg multiple testing correction. MAIN RESULTS Significant differences were seen in endometrial gene expression, related to the type of ovulation trigger and luteal phase support. However, the endometrial gene expression after the GnRH agonist trigger and a modified luteal phase support (B) was similar to the pattern seen after the hCG trigger (A). LIMITATIONS, REASONS FOR CAUTION The study was performed in four oocyte donors only; however, it is a strength of the study that the same donor underwent four consecutive stimulation protocols within 1 year to avoid inter-individual variations. WIDER IMPLICATIONS OF THE FINDINGS These endometrial gene-expression findings support the clinical reports of a non-significant difference in live birth rates between the GnRH agonist trigger and the hCG trigger, when the GnRH agonist trigger is followed by a bolus of 1500 IU hCG at 35 h post trigger in addition to the standard luteal phase support. STUDY FUNDING/ COMPETING INTERESTS This study was supported by an un-restricted research grant by MSD Belgium. TRIAL REGISTRATION NUMBER EudraCT number 2009-009429-26, protocol number 997 (P06034).

Abstract
Leiomyomata of the urinary and male genital tract are extremely rare. They have been reported throughout the genitourinary male tract and the most common localization is the renal capsule. However, leiomyomas of the epididimis, spermatic cord, tunica albuginea and testis have been reported. We report diagnostic confirmation of a paratesticular leiomyoma in an azoospermic patient undergoing a testicular sperm extraction for intracytoplasmic sperm injection (TESE/ICSI) procedure.

Abstract
OBJECTIVE To assess the prevalence of chronic endometritis and the impact on the fertility of asymptomatic patients indicated for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment. DESIGN In the context of a randomized controlled trial, a hysteroscopy-guided endometrial biopsy was obtained and histologically examined. The live birth rate (including spontaneous pregnancies) after initiation of IVF/ICSI treatment of patients diagnosed with chronic endometritis was compared with the live birth rate of a randomly selected matched control group of patients without endometritis. SETTING Two tertiary infertility care units. PATIENT(S) A total of 678 asymptomatic infertile women with a normal transvaginal ultrasound (TVS) who underwent diagnostic hysteroscopy before a first IVF/ICSI treatment cycle. INTERVENTION(S) Hysteroscopy guided endometrial biopsy. MAIN OUTCOME MEASURE(S) The prevalence of chronic endometritis and the live birth rate (including spontaneous pregnancies) within 3 years after initiation of the randomized controlled trial. RESULT(S) The prevalence of chronic endometritis in the 606 patients with an adequate biopsy was 2.8%. The cumulative live birth rate (including spontaneous pregnancies) did not significantly differ between patients with or without endometritis: 76% versus 54%. Also, the clinical pregnancy rate per embryo transfer was not significantly different (hazard ratio 1.456, 95% confidence interval 0.770-2.750). CONCLUSION(S) Chronic endometritis can be rarely diagnosed in a population of asymptomatic infertile patients with a normal TVS before a first IVF/ICSI treatment. Moreover, the reproductive outcome after initiation of IVF/ICSI was not found to be negatively affected by chronic endometritis. In conclusion, the clinical implication of chronic endometritis seems minimal.

Abstract
Pseudomyxoma peritonei is only rarely seen in conjunction with primary ovarian tumors. It has been suggested that only ruptured mucinous tumors arising in ovarian mature cystic teratomas can result in this clinical picture. We describe a case of a late invasive recurrence of a mucinous intestinal-type borderline ovarian tumor arising from a mature teratoma after complete surgical debulking. Borderline ovarian tumors behave indolently in the overwhelming majority of cases, and the prognosis is therefore usually outstanding.

Abstract
OBJECTIVES A prospective study was carried out to evaluate the role of intra-operative touch imprint cytology (TIC) in the assessment of sentinel lymph node (SLN) involvement for staging and treatment of early-stage, clinically node-negative breast carcinoma. METHODS Forty-five patients with early-stage, clinically node-negative breast cancer underwent a SLN biopsy with intra-operative TIC. The SLN was bisected if its width was less than 4 mm or sliced every 2 mm if it was more than 4 mm. The imprint specimens were stained with haematoxylin and eosin (H&E). Rapid immunochemistry (IH) was performed in case of equivocal cytological result. Permanent sections were evaluated with H&E and IH staining. The results of TIC were compared to histopathological results. RESULTS The sensitivity, specificity and overall accuracy of TIC on a node basis were 65.5%, 96.3%, 85.5%, respectively. When calculated according to the size of SLN metastasis, the sensitivity of TIC for overt metastasis was 84.6%, while it was 62.5% for micrometastasis and 37.5% for sub-micrometastasis. The mean size of nodal metastasis was 5.08 mm and 1.25 mm for true positive and false negative results, respectively (P = 0.0236). Because of intra-operative TIC, 76.5% of the patients who needed further axillary lymph node dissection (ALND) could undergo this during the same operating time. CONCLUSIONS TIC is a rapid and reliable method for the intra-operative assessment of metastatic sentinel node involvement in patients with early-stage, clinically node-negative breast carcinoma. Despite a low sensitivity comparable to frozen section (FS) in detecting micro- and sub-micrometastases, the technique offers the advantage of full tissue preservation for subsequent histological analysis.

Abstract
A European Federation of Cytology Societies (EFCS) working party of 28 members from 14 European countries met at the European Congress of Cytology in Lisbon in September 2009, with two observers from the USA, to discuss the need for standardising thyroid FNA nomenclature in the light of the National Institute of Cancer (NCI) recommendations resulting from the State of the Science conference in Bethesda in 2007. The data were obtained through two questionnaires sent by email and a transcript of the live discussion at the congress, which is presented in full. The surveys and discussion showed that there were currently no national terminologies for reporting thyroid FNA in the different European countries except in Italy and the UK. Personal, 'local', surgical pathology and descriptive terminologies were in use. All but one of the working party members agreed that thyroid FNA reporting should be standardised. Whilst almost a third would adopt the NCI Bethesda terminology, which offers the advantages of a 'risk of cancer' correlation and is linked to clinical recommendations, more than half favoured a translation of local terminology as the first step towards a unified nomenclature, as has been done recently in the UK. There was some disagreement about the use of: a) the six-tiered as opposed to four or five-tiered systems, b) the use of an indeterminate category and c) the 'follicular neoplasm' category, which was felt by some participants not to be different from the 'suspicious of malignancy' category. The conclusions will be passed to the different national societies of cytology for discussion, who will be asked to map their local terminologies to the Bethesda classification, observe its acceptance by clinicians and audit its correlation with outcome.

Abstract
BACKGROUND The aims of this study were to analyze cytomorphological features of Tripath PREP (BD SurePath, Burlington, NC) preparations in thyroid nodules and to examine adequacy and accuracy of SurePath and frozen sections for both clinical outcome and histological diagnosis when applicable. METHODS Gathered during a period of 4 years, 712 SurePath specimens of the thyroid were included. Histological (n = 207) or clinical follow-up (n = 505) was available in all cases. During the same period, 253 frozen sections of surgical thyroid resection specimens were also assessed. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were calculated. RESULTS Sensitivity was 77% for SurePath and 29% for frozen section; specificity was 81% for SurePath and 100% for frozen section; accuracy was 80% for SurePath and 90% for frozen section. One hundred seventy-eight (25%) SurePath patients were considered unsatisfactory for diagnosis. In this study, sensitivity, specificity, and accuracy were comparable for SurePath and other reported results of liquid-based thyroid cytology. Presence of free colloid or pure cystic changes favored a benign diagnosis. Cellular smears with nuclear atypia of papillary carcinoma allowed an overt diagnosis of malignancy. CONCLUSIONS The authors concluded that SurePath is a reliable technique for assessment of thyroid nodules and offers the advantage of easy identification of colloid and atypical nuclei. Supplementary frozen section analysis should be limited to an FNAC diagnosis of suspicious for papillary carcinoma.

Abstract
BACKGROUND Grafting of frozen-thawed testicular tissue has been suggested as a novel fertility preservation method for patients undergoing gonadotoxic treatments. However, this technique still needs further optimization before any clinical application. So far, grafting of human testicular tissue has only been performed to the back skin of nude mice and has shown spermatogonial stem-cell survival and occasionally differentiation up to primary spermatocytes. In this study, orthotopic grafting to mouse testes was evaluated as an alternative, and the effect of freezing and the donor's age was studied. METHODS Human testicular tissue was obtained from two prepubertal (aged 3 and 5) and two postpubertal (aged 12 and 13) boys. Both fresh and frozen-thawed testicular tissue was grafted to the testis of immuno-deficient nude mice. Four and nine months after transplantation, testes were analyzed by histology and immunohistochemistry. RESULTS Four and nine months after transplantation, spermatogonial stem cells were observed in all tissue grafts. Germ cell survival was found to be higher in xenografts from the older boys when compared with that from younger donors. Furthermore, no differentiation was observed in the xenografts from younger patients, but the grafts of two older donors showed differentiation up to the primary spermatocyte level, with the presence of secondary spermatocytes in the oldest donor 9 months after transplantation. CONCLUSIONS This xenografting study shows that intratesticular grafting results in high germ cell survival. In grafts derived from the older boys, meiotic activity was maintained in the xenografts for at least 9 months. Although difficult to conduct due to the scarcity of the tissue, more comparative research is needed to elucidate an optimal grafting strategy.

Abstract
Langerhans Cell histiocytosis is a rare proliferative histiocytic disorder in which pathologic Langerhans cells accumulate in a variety of organs. The clinical presentation, evolution and therapeutic options are highly variable. Because of its relative rarity and the broad clinical spectrum, the diagnosis of Langerhans cell histiocytosis is often delayed or missed. At present, many questions with respect to aetiology, pathogenesis and treatment remain unanswered. In the present article we want to raise the awareness of this rare disease in adults and its diversity by the means of two case reports. In addition, the clinical manifestations, diagnosis and the current management are reviewed.

Abstract
OBJECTIVE To determine the human endometrial transcriptome during embryonic implantation. DESIGN Case report. SETTING Tertiary fertility center. PATIENT(S) A 24-year-old woman who inadvertently became pregnant during an endometrial biopsy procedure. INTERVENTION(S) An endometrial biopsy was performed with a Pipelle device during the midluteal phase (days 19-21) of the cycle; blood samples for hormonal assessments were collected and a transvaginal ultrasound was performed. MAIN OUTCOME MEASURE(S) Gene expression analysis of the endometrium during the window of implantation (during the implantation of an embryo) in a natural cycle. Localization of selected genes in endometrial tissue with immunohistochemistry. RESULT(S) A total of 394 probe sets were differentially expressed in the pregnant sample when compared with the midsecretory phase nonpregnant endometrial samples. Different gene networks were involved, and selected genes from these signaling pathways were confirmed at the protein level. CONCLUSION(S) Endometrial gene expression of a pregnant patient in a natural cycle is significantly different from nonpregnant patients during the midsecretory phase.

Abstract
Providing valid risk estimates of a genetic disease with variable age of onset is a major challenge for prevention strategies. When data are obtained from pedigrees ascertained through affected individuals, an adjustment for ascertainment bias is necessary. This article focuses on ascertainment through at least one affected and presents an estimation method based on maximum likelihood, called the Proband's phenotype exclusion likelihood or PEL for estimating age-dependent penetrance using disease status and genotypic information of family members in pedigrees unselected for family history. We studied the properties of the PEL and compared with another method, the prospective likelihood, in terms of bias and efficiency in risk estimate. For that purpose, family samples were simulated under various disease risk models and under various ascertainment patterns. We showed that, whatever the genetic model and the ascertainment scheme, the PEL provided unbiased estimates, whereas the prospective likelihood exhibited some bias in a number of situations. As an illustration, we estimated the disease risk for transthyretin amyloid neuropathy from a French sample and a Portuguese sample and for BRCA1/2 associated breast cancer from a sample ascertained on early-onset breast cancer cases.
