Abstract
INTRODUCTION The sensorineural acuity level (SAL) test was developed as an alternative assessment to estimate bone conduction (BC) thresholds in cases where masking problems occur in pure tone audiometry (PTA). Nevertheless, prior to its clinical application, the respective SAL normative data must be made available. As such, the present study was carried out to establish SAL normative data using an insert earphone and two different commercially available bone transducers. Additionally, to determine the effect of earphone type on SAL test results, it was also of interest to compare the present study's findings with those of a previous study (that used a headphone to derive SAL normative data). MATERIALS AND METHODS In this repeated-measures study, 40 Malaysian adults (aged 19-26 years) with normal hearing bilaterally (based on PTA results) were enrolled. They then underwent the SAL test based on the recommended protocol by Jerger and Tillman (1960). The SAL normative data for each ear were obtained by calculating the differences between air conduction (AC) thresholds in quiet and AC thresholds in noise by means of insert earphone, B71 and B81 bone vibrators. RESULTS The SAL normative values were comparable between the ears (p > 0.05), and the data were pooled for subsequent analyses (n = 80 ears). Relative to B81 bone transducer, B71 bone vibrator produced statistically higher SAL normative data at all frequencies (p < 0.05). The SAL normative values established by the present study were statistically lower than those of the previous study (that utilised headphones) at most of frequencies tested (p < 0.05). CONCLUSIONS The SAL normative data produced by the two bone vibrators were significantly different. The SAL normative values were also affected by the type of earphone used. While conducting the SAL test on Malaysian patients, the information provided by this study can be useful to guide the respective clinicians in choosing the appropriate normative data.

Abstract
The present work is aimed at improving the multicellular dosimetry of several Auger radionuclides of interest for targeted cancer therapy, including 99mTc, 111In, 123I, 125I, and 201Tl. For this purpose, using the Geant4-DNA Monte Carlo code, a cluster of 13 similar spherical cells with a hexagonal packed arrangement was modeled, and the mean absorbed doses per unit cumulated activity (S-values) were calculated by considering two target←source configurations, cell←cell and nucleus←nucleus. The obtained ratios of cross-dose to self-dose S-value in terms of the distance between the source and target regions were evaluated and also compared to those estimated by the Medical Internal Radiation Dose (MIRD) method. Besides, the contribution of the Coster-Kronig, Auger and internal conversion electrons to the S-values was provided for each radionuclide. According to the results, it can be concluded that in contrast to self-absorption, the cross-absorption due to the Auger-emitters has not a significant role in the total energy deposition within a cell in the cluster.

Abstract
Abstract
Study question
Can standard morphological assessment of blastocyst quality accurately predict first trimester miscarriage?
Summary answer
Decreasing trophectoderm and inner cell mass grade equally predicted first trimester miscarriage independently. After adjusting for confounders, poor embryo quality was not associated with miscarriage.
What is known already
Embryo quality determined by morphological assessment is a well-established predictor of successful implantation and live birth with in vitro fertilization treatment. Chromosomal abnormalities account for over half of first trimester miscarriages, and links between ploidy status and embryo morphology have been demonstrated. However, the association between blastocyst morphology and first trimester miscarriage is still poorly understood with consensus opinion yet to be established.
Study design, size, duration
This single centre retrospective cohort study included 2020 fresh and frozen single embryo transfers between October 2010 and October 2020. Blastocyst degree of expansion, inner cell mass (ICM) grade, and trophectoderm (TE) grade were compared for 354 pregnancies ending in first trimester miscarriage and 1666 pregnancies that surpassed 12 weeks of gestation. The association between blastocyst morphology and miscarriage was examined by logistic regression analysis.
Participants/materials, setting, methods
All single blastocyst transfers over a 10-year period resulting in first trimester miscarriage or pregnancy beyond 12 weeks of gestation were included in our analysis. Cycles involving donor oocytes, preimplantation genetic testing, resulting in biochemical pregnancy, or ectopic pregnancy were excluded. Differences between groups were analysed with chi-square and logistic regression analysis. Odds ratios (aOR) for miscarriage versus ongoing pregnancy were adjusted for maternal age, cycle type, blastocyst expansion, ICM grade, and TE grade.
Main results and the role of chance
Out of 2020 single embryo transfer cycles, a total of 354 resulted in first trimester miscarriage (17.5%). Independently, miscarriage rates increased with decreasing ICM grade (A to C; 14.6%, 18.9%, and 26.5%, p = 0.003) and TE grade (A to C; 14.6%, 17.7%, and 26.6%, p = 0.004). Univariate logistic regression showed higher risks of miscarriage with ICM grade C compared to ICM grade A (OR 2.241, 95%CI 1.292-3.886, p = 0.004), TE grade C compared to TE grade A (OR 2.116, 95%CI 1.360 – 3.292, p = 0.001), and expansion grades of 1 and 2 compared to expansion of 5 and 6 (OR 2.514, 95%CI 1.477 – 4.278, p = 0.001). After multivariable logistic regression adjusting for maternal age at embryo transfer, cycle type, and all morphological parameters (degree of expansion, ICM, and TE), only expansion grade of 1 and 2 showed a statistically significant association with first trimester miscarriage.
Limitations, reasons for caution
The main limitation of this study is the retrospective design of the analysis, and subjective nature of embryo morphological assessment. There may also be residual confounding by unknown or unmeasured confounders such as paternal age or maternal BMI.
Wider implications of the findings
Embryo selection for transfer should continue to be guided by standard morphological assessment. Decreasing grade of ICM and TE are both positively associated with an increased miscarriage risk, while poorly expanded blastocysts are most predictive of first trimester miscarriage. Patients undergoing embryo transfer should be adequately counselled about these risks.

Abstract
Abstract
Study question
Is there a role for elective single blastocyst transfer (eSBT) in advanced maternal age?
Summary answer
Double blastocyst transfer (DBT) versus eSBT resulted in higher live birth rates except for those undergoing their first cycle.
What is known already
Women with advanced maternal age are generally considered poorer prognosis patients with lower live birth rates compared to their younger counterparts. This often results in a higher likelihood of double embryo transfer in this group. This is not without risk as multiple pregnancy is associated with significant maternal and neonatal morbidity especially with advancing maternal age. In older women with blastocysts available for transfer, it is unclear who should be recommended double versus elective single transfer. The concept of the “good-prognosis” older woman remains elusive.
Study design, size, duration
This was a retrospective observational study looking at 511 IVF/ICSI cycles between January 2010 and January 2020. Treatment cycle details and clinical outcomes were entered prospectively into a dedicated clinic database. Data was retrieved and analysed using SPSS V25.
Participants/materials, setting, methods
The study was conducted in a large London IVF centre. Data was collected on women aged 40 or above undergoing an IVF/ICSI cycle with eSBT (Group 1, n = 79) or DBT (Group 2, n = 430). Women with more than three previous IVF attempts were excluded. eSBT was defined as a single blastocyst transfer with at least one further blastocyst available for cryopreservation. Subgroup analysis was performed for those undergoing their first cycle.
Main results and the role of chance
Data from 511 cycles was analysed. The mean age was 40.6±1.2years. The live birth rate was 27%. Group 1 was marginally younger (40.2±0.6 v 40.8±1.2, p < 0.005) and was more likely to be undergoing their first IVF cycle (84% v 68%, p = 0.003). Those in Group 1 had more eggs collected (13.6±7.3 v 11.3±5.5, p = 0.009), more zygotes (8.9±4.7 v 7.3±3.6) formed and more blastocysts frozen (3.4±2.6 v 1.1±1.7, p < 0005). More women in Group 1 had a top quality blastocyst (expansion of > 2 and inner cell mass and trophectoderm of AA, AB, BA or BB) transfer (91% v 71%, p < 0.005).
After logistic regression controlling for maternal age, number of previous IVF cycles and blastocyst quality, Group 1 had a lower likelihood of livebirth (aOR 0.550, 95%CI 0.306-0.988) but with a significantly lower multiple pregnancy rate (0% v 24%, p = 0.024).
Importantly, for those undergoing their first IVF cycle (n = 359), there was no difference in live birth rate in the two groups (aOR 0.617, 95%CI 0.329-1.156) after controlling for age and blastocyst quality but Group 2 had a higher multiple pregnancy rate (24% v 0%, p = 0.020).
Limitations, reasons for caution
This study is limited by its retrospective nature putting it at risk of information bias as it relied on accurate documentation of studied variables into the patient database. The study did not examine cumulative birth rates of fresh and subsequent frozen cycles in Group 1.
Wider implications of the findings
Women should have individualised counseling about number of blastocysts to transfer taking into account their circumstances. Those undergoing their first IVF attempt and with a blastocyst available for transfer, should be counselled that DBT is associated with a higher multiple pregnancy rate with no increase in overall live birth rate.

Abstract
OBJECTIVES To examine the association between inferior vena cava (IVC) diameter and postpartum blood loss and assess whether IVC diameter is a useful marker in the evaluation of intravascular volume status in women with postpartum hemorrhage (PPH). METHODS This was a prospective case-control study conducted in a university medical teaching center in Afula, Israel, between November 2018 and March 2020. The study cohort consisted of women with a singleton pregnancy who delivered vaginally at term. The PPH group included women diagnosed with PPH based on visually estimated blood loss of 1000 mL or more at the time of enrolment. Hemodynamically unstable women or women with major bleeding at the time of diagnosis were not included. The control group consisted of women with an uneventful fourth stage of labor. IVC diameter was measured using transabdominal ultrasonography during inspiration (IVCi diameter) and expiration (IVCe diameter), and the collapsibility index was calculated ((IVCe - IVCi)/IVCe × 100). The primary outcome was the percentage difference in IVC diameter and collapsibility index between the PPH group and controls. The performance of the IVC collapsibility index in the prediction of the need for blood transfusion in women with PPH was assessed. In order to demonstrate a difference of 20% with a power of 80% and alpha of 0.05, 108 women, at a ratio of 1:2 in the study and control groups, respectively, were needed. RESULTS Overall, 36 and 72 women were included in the final analysis in the PPH and control groups, respectively. IVCi and IVCe diameters were significantly smaller in the PPH group (0.93 ± 0.30 cm and 1.26 ± 0.32 cm, respectively) than in controls (1.42 ± 0.31 cm and 1.75 ± 0.28 cm, respectively) (P = 0.001 for both). The percentage reductions in IVCi and IVCe diameters in the PPH group compared with controls were 35.0% and 28.0%, respectively. IVC collapsibility index was increased significantly, by 42.9% (26.04 ± 8.67% vs 18.15 ± 5.07%; P = 0.001) in the PPH group compared with controls. IVC collapsibility index was a significant predictor of the need for blood transfusion and correctly predicted 81% of cases. Logistic regression analysis demonstrated that IVC collapsibility index was also a significant predictor of a drop in hemoglobin level of ≥ 2 g/dL (P = 0.001). CONCLUSIONS IVC diameter changes in response to postpartum blood loss. Measurement of IVC diameter using transabdominal ultrasonography is an objective and useful non-invasive method for the early evaluation of intravascular volume status in women with PPH and for the prediction of cases that might require blood transfusion. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Thiophene derivatives, namely (E)-thiophene-2-carbaldehyde oxime (OXM) and (E)-5-(thiophen-2-yl)-1H-tetrazole (TET), were synthesized and characterized via1H and 13C NMR. Furthermore, their inhibitory property for AA2024-T3 in 1 M HCl solution was investigated via electrochemical impedance spectroscopy and potentiodynamic polarization at 293 K, together with DFT/B3LYP-based calculations. Numerous global and local descriptors of reactivity such as EHOMO, ELUMO, energy gap, electronegativity (χ), hardness (η), and frontier molecular orbital repartitions were investigated to describe the reactivity of each molecule. Alternatively, Monte Carlo simulations were performed under the solvation condition on the Al (111) surface to understand the adsorption behavior of the as-studied inhibitors deeply. The inhibition efficiency increased with an increase in the inhibitor concentration, achieving maximum values of 94.0% and 96% at 10−3 M, respectively. The polarization curves showed that the examined compounds act as mixed-type inhibitors. In addition, the adsorption of these compounds obeyed the Al Awady, Flory-Huggins and Temkin isotherms. The surface characterization analysis via SEM/EDX confirmed the presence of a barrier layer covering the aluminum surface. The experimental inhibition efficiencies were correlated with global descriptors, which confirmed that this theoretical study is useful for the protection of aluminum alloy metal in an acidic medium. Thiophene derivatives: thiophene-2-carbaldehyde oxime (OXM) and 5-(thiophen-2-yl)-1H-tetrazole (TET), were synthesized and characterized. Furthermore, their inhibitory property for AA2024-T3 in 1 M HCl solution was investigated via electrochemical and with theoretical study.![]()

Does mild ovarian stimulation in women with PCO result in higher live birth rates during subsequent FET cycles?
Summary answer
Mild ovarian stimulation with FSH doses <150IU did not result in higher clinical pregnancy or livebirth rates in subsequent FET.
What is known already
Ovarian stimulation during IVF in women with PCO is associated with an exaggerated response, ovarian hyperstimulation syndrome, poor egg to follicle ratio, low fertilisation rates and poor blastocyst conversion. Mild ovarian stimulation, often referred to as protocols with FSH doses under 150IU, is often employed to overcome these challenges. One of the perceived benefits of this approach is improved oocyte and embryo quality reflected in lower aneuploidy rates.
Study design, size, duration
This was a retrospective observational study looking at 99 FET between January 2011 and Jan 2021 that followed a fresh cycle in women with a pre-treatment antral follicle count of 12 + 12 or greater. Patients were identified through the antral follicle count at the pre-treatment investigation ultrasound scan. Ultrasound findings, treatment cycle details and clinical outcomes were entered prospectively into a dedicated clinic database. Data was retrieved and analysed using SPSS V25.
Participants/materials, setting, methods
The study was conducted in a large IVF centre. Data on women with an AFC of 12 + 12 or above, undergoing an autologous FET cycle following a fresh cycle were collected. Women were split into those receiving <150IU of FSH (Group1, n = 51) and those receiving FSH ³150 IU (Group 2, n = 48). Binary logistic regression analysis was performed to control for confounders. Live birth was the primary outcome, with biochemical and clinical pregnancy being secondary outcomes.
Main results and the role of chance
Women in Group 1 were younger (30.8±3.6 v 33.8±3.65, p < 0.005) but had a similar antral follicle count (38.2±11.7 v 34.2±9.1, p = 0.07). The total number of eggs collected (24.1±13.8 v 25.9±8.8, p = 0.45) and fertilisation rate (0.59±0.2 v 0.58±0.18, p = 0.77) during their fresh cycle were comparable. Women in Group 2 had a larger number of embryos suitable for cryopreservation (7.36±4.2 v 4.8±3.5, p = 0.001)
In the subsequent frozen embryo replacement cycle, there was no difference in the number or quality of embryos transferred with most women having a single embryo transfer (63% v 48%, p = 0.14) and at least one top quality embryo transferred (68.6% v 81%, p = 0.15). There was a higher biochemical pregnancy rate in Group 1 (84% v 66%, p = 0.035) but with no difference in clinical pregnancy rate (53% v 44%, p = 0.37) or live birth rate (49% v 42%, p = 0.76). Live birth rates remained comparable even after controlling for age, and number and quality of embryos transferred (OR: 1.21 (95% CI 0.50–2.94).
Limitations, reasons for caution
This was a retrospective analysis raising the risk of allocation bias. This study was also at risk of information bias as it relied on accurate documentation of the AFC at the pre-treatment scan.
Wider implications of the findings: Patients can be reassured that both stimulation protocols result in similar live birth rates in subsequent frozen embryo replacement cycles.
Prospective trials using PGT-A are required to assess whether aneuploidy could account for the discrepancy in biochemical pregnancy rates in the two groups considering the subsequent comparable clinical pregnancy rates.

Abstract
Sudden sensorineural hearing loss (SSNHL) is an otology emergency and carries significant morbidity if the diagnosis is missed. It can present to any specialty but in our local setting the patient usually presents to primary care as it is easily accessible. We present a case of SSNHL that was initially presented to a primary care centre and the patient was reassured without any investigation being carried out. SSNHL has many causes thus making diagnosis difficult. However, with knowledge of its possible, a diagnosis can be made and appropriate management can be advocated to the patient. Hence, we discuss the three main causes of SSNHL, while emphasizing the immune system-mediated mechanism as the main cause in this case.

Abstract
Foreign body aspiration is commonly described in infants and children. However, recently, a new high-risk group was identified among young women, especially those from the Muslim population who wear the traditional hair scarf. This is due to the habit of holding the scarf pin in between the lips to free hands to adjust the scarf more easily. Talking, laughing, or coughing while fixing the scarf may result in inadvertent inhalation of the pin into the tracheobronchial tree. We present a case of scarf pin inhalation and the challenges encountered in managing this patient during the successful removal of the pin via flexible bronchoscopy under fluoroscopy guidance. This particular case was technically challenging for us as the sharp tip of the needle was pointing upward and piercing the bronchial mucosa.

Abstract
OBJECTIVE Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic condition, predominantly related to the hormone used to induce oocyte maturation during IVF treatment. Kisspeptin is a hypothalamic neuropeptide that has recently been demonstrated to safely trigger final oocyte maturation during IVF treatment even in women at high risk of OHSS. However, to date, the safety of kisspeptin has not been compared to current hormonal triggers of oocyte maturation. DESIGN We conducted a retrospective single-centre cohort study investigating symptoms and clinical parameters of early OHSS in women at high risk of OHSS (antral follicle count or total number of follicles on day of trigger ≥23) triggered with human chorionic gonadotrophin (hCG) (n = 40), GnRH agonist (GnRHa; n = 99) or kisspeptin (n = 122) at Hammersmith Hospital IVF unit, London, UK (2013-2016). RESULTS Clinical Parameters of OHSS: Median ovarian volume was larger following hCG (138 ml) than GnRHa (73 ml; P < .0001), and in turn kisspeptin (44 ml; P < .0001). Median ovarian volume remained enlarged 20-fold following hCG, 8-fold following GnRHa and 5-fold following kisspeptin compared to prestimulation ovarian volumes. Mean (±SD) ascitic volumes were lesser following GnRHa (9 ± 44 ml) and kisspeptin (5 ± 8 ml) than hCG (62 ± 84 ml; P < .0001). Symptoms of OHSS were most frequent following hCG and least frequent following kisspeptin. Diagnosis of OHSS: The odds ratio for OHSS diagnosis was 33.6 (CI 12.6-89.5) following hCG and 3.6 (CI 1.8-7.1) following GnRHa, when compared to kisspeptin. CONCLUSION Triggering oocyte maturation by inducing endogenous gonadotrophin release is preferable to the use of exogenous hCG in women at high risk of OHSS.

Abstract
INTRODUCTION A foreign body (FB) in the upper aerodigestive tract is a fairly common encounter. Fish bones are the commonest FB seen in adults. The commonest presentation is odynophagia. Usually, the patient will point at the level of FB on the neck to indicate the location. METHODS Clinical report. RESULTS This case report describes a large FB in an adult with underlying infantile cerebral palsy. Besides dysphagia, it was associated with drooling of saliva and pain in the throat region. CONCLUSION FB ingestion with complete obstruction of the oesophagus is an emergency. It may cause total dysphagia as the passage of food is completely blocked.

Abstract
Background The aim of this study was to evaluate the clinical and microbiological effects of local application minocycline HCl 2% gel, used as an adjunct to scaling and root planing (SRP) for treatment of chronic periodontitis (CP). CP is an inflammation of periodontal tissue that is caused mainly by bacterial infection, where periodontal destruction such as loss of attachment and bone destruction occurred. Methods A total of 81 subjects with moderate to severe periodontitis whose baseline clinical attachment loss (CAL) was ≥4 mm were randomly assigned to receive SRP alone (control group, N=39) or SRP followed by four times of local application of minocycline HCl gel (Periocline) once a week (test group, N=42). Pocket depth, CAL, and papilla bleeding index were examined at baseline, 21 days, 2, 3, and 6 months. Subgingival plaque samples were collected with sterile curettes and were analyzed by real-time polymerase chain reaction for the presence of three periodontal pathogens (Porphyromonas gingivalis [P.g.], Tannerella forsythia [T.f.], and Treponema denticola [T.d.]) at baseline, 2, 3, and 6 months. Results The number of bacteria was reduced in both groups at 2 months after baseline (SRP treatment). The changes (2–6 months) in T.d. and T.f. counts in the test group were significantly lower than those in the control group. In the control group, a significant regrowth of P.g., T.f., and T.d. was observed from 2 to 6 months and of P.g. and T.f. from 3 to 6 months. On the other hand, in the test group, the number of the three bacteria did not significantly increase during the 6-month period. Conclusion The results showed that local application of minocycline, used as an adjunct to SRP, was effective for suppressing regrowth of periodontal pathogens, suggesting its risk reduction of recurrent periodontal pathogens in CP.

Abstract
OBJECTIVES To compare the efficacy, safety and satisfaction from two modes of oral analgesia administration for the treatment of post-caesarean pain in the first 48 h following surgery: on-demand versus fixed time interval administration. DESIGN Open label parallel-group, randomised-controlled trial from February to December 2013. SETTING University-affiliated hospital in Israel. POPULATION Two-hundred women who underwent caesarean delivery with regional anaesthesia. METHODS Patients were randomly assigned to receive predetermined combinations of tramadol, paracetamol and diclofenac either following patient demand or at predetermined 6-h intervals for the first 48 h. If the patient requested additional analgesia, Percocet (oxycodone and paracetamol) was given as a rescue treatment. MAIN OUTCOME MEASURES Pain intensity and satisfaction were self-evaluated with visual analogue scale of 0 (no pain/least satisfaction) to 10 (worst pain/highest satisfaction). Breastfeeding, need for supplemental formula, and maternal and neonatal adverse effects were also evaluated. RESULTS The 'fixed time interval' group, compared with the 'on-demand' group, had lower mean pain score (2.8 ± 0.84 versus 4.1 ± 0.48, respectively; P < 0.0001), higher satisfaction rate (9.1 ± 1.2 versus 8.3 ± 1.5, respectively; P < 0.0001), more breastfeeds (23.7 ± 6.5 versus 19.2 ± 6.2, respectively; P < 0.0001) and less use of supplemental formulas (8.2 ± 5.2 versus 11.9 ± 6.5, respectively; P < 0.0001). The number of times that drugs were given was slightly higher in the 'fixed time interval' group without an increase in maternal adverse effects, which were mild. No adverse effects were reported for the neonates. CONCLUSION Administration of oral analgesia in fixed time intervals is superior to drug administration following patient demand without increasing maternal or neonatal adverse outcomes. TWEETABLE ABSTRACT Oral analgesia in fixed time intervals is superior to analgesia following demand.

Abstract
OBJECTIVE To assess the impact of non-cavity-distorting fibroids on in vitro fertilisation (IVF) pregnancy outcomes. DESIGN A retrospective, matched, single-centre, cohort study was performed. SETTING The IVF unit of a tertiary, university hospital. POPULATION We analysed all women with non-cavity-distorting uterine fibroids undergoing IVF/intracytoplasmic sperm injection (ICSI) cycles from 1 January 2011 to 1 May 2015. METHODS Each woman was matched with two separate controls of the same age (±6 months), stimulation protocol (gonadotropin-releasing hormone agonist or antagonist), starting dose of follicle-stimulating hormone (FSH), number of embryos transferred (one or two), day of transfer (day 3 or day 5), and no uterine fibroids identified by transvaginal ultrasound. MAIN OUTCOME MEASURES Clinical pregnancy and live birth rates. RESULTS Our study demonstrates that the presence of non-cavity-distorting fibroids appears to negatively affect clinical pregnancy (odds ratio, OR 0.62; 95% confidence interval, 95% CI 0.41-0.94) and live birth rates (OR 0.58; 95% CI 0.48-0.78) in patients undergoing their first IVF/ICSI cycle, when matched with controls of the same age, starting dose of FSH, stimulation protocol, number of embryos, and day of embryo transfer. The deleterious effect of fibroids on live birth rates was significant in women with two or more fibroids (OR 0.47; 95% CI 0.26-0.83) and in women with fibroids of ≥30 mm in diameter (OR 0.41; 95% CI 0.19-0.89). The negative impact of non-cavity-distorting fibroids was also present in women with an embryo transfer on day 5 (OR 0.58; 95% CI 0.35-0.94). Conversely, in women with single fibroids of <30 mm in diameter, no difference in pregnancy outcomes was identified. CONCLUSIONS A well-designed, adequately powered, randomised controlled trial is required to address the role of medical or surgical interventions in patients with intramural and subserosal fibroids before undergoing fertility treatment.

Abstract
OBJECTIVE To examine the risk of subsequent preterm birth after cervical ripening using a balloon catheter. STUDY DESIGN A retrospective study was held at a university teaching hospital between January 2007 and June 2013. The study group included women who underwent cervical ripening using a balloon (single or double) catheter in the previous pregnancy followed by a subsequent singleton delivery (balloon catheter group). Two control groups were included. The first was similar to the study group except that ripening was achieved in the previous pregnancy with vaginal prostaglandin E2 (PGE2 group). The second control group had a previous pregnancy that resulted in spontaneous onset of labor at term (unexposed group). The primary outcome was the incidence of spontaneous preterm birth (before 37 weeks) in the index pregnancy. RESULT Overall, 558 women were included; each group consisted of 186 women. The incidence of spontaneous preterm birth in the index pregnancy did not differ between the groups (0.5, 1.6 and 2.7% in the balloon catheter, PGE2 and in the unexposed groups, respectively, P=0.31). Among the balloon catheter group, 58 (31.2%) women had the ripening performed with a single-balloon catheter and 128 (68.8%) women with a double-balloon catheter. The rate of the spontaneous preterm birth in the index pregnancy did not differ between the two groups (P=1.0). CONCLUSION Cervical ripening with a balloon catheter does not increase the rate of subsequent spontaneous preterm birth.

Abstract
Removal of cadmium from aqueous solutions using 20 species of plant leaves and combinations of these leaves have been studied. Several factors affecting the removal efficiency have been studied. The most efficient types of plant leaves for the removal of cadmium are those of styrax, plum, pomegranate and walnut. The interaction effect of the combined leaf samples on the efficiency of removal of cadmium has been found to be additive in combinations involving styrax plant leaves but seems to be antagonistic in all other combinations. The optimum experimental conditions for removal of cadmium have been found to be at pH 4.1, using high concentrations of naturally dried plant leaves, using ground leaves and to remove cadmium from agitated aqueous solutions. The percentage of metal removed at an initial cadmium concentration of 10mg/l by the most efficient types of leaves have been found to be 85% for styrax leaves, 85% for plum leaves, 80% for pomegranate leaves, 78% for walnut leaves and 77% for meddler leaves. The presence of foreign ions or complexing agents has been found to reduce the efficiency of removal of cadmium by plant leaves. About 80-85% of the cadmium in charged plant leaves has been released under the influence of changing the pH of the solution, addition of competing ions and the addition of EDTA. The results of removal of cadmium by plant leaves have been found to follow the Freundlich adsorption isotherm, first-order reaction with respect to cadmium and to have intra-pore diffusion as the rate-limiting step.

Abstract
We aim to assess the feasibility and efficacy of laparoscopic oophorectomy in women with pelvic pain after hysterectomy in this retrospective review of 35 consecutive women presenting with pelvic pain who had had their ovaries conserved at the time of hysterectomy. Pain was attributed to the presence of these residual ovaries if there was an adnexal mass--or the pain improved following ovarian suppression with a GnRH analogue. The procedure was completed laparoscopically in 32 (91%) women. Overall, 27 (77%) women reported symptomatic relief following surgery. We conclude that laparoscopic oophorectomy is safe and provides symptomatic relief in this group of women.

Abstract
OBJECTIVE To compare the concentration of glycodelin in uterine flushing at the implantation window obtained from women with subseptate uteri, women with a history of recurrent first trimester miscarriage and fertile controls. STUDY DESIGN Glycodelin concentration was assessed using Enzyme Linked Immunohistochemistry (ELISA) at The Early Pregnancy & Gynaecology Assessment Unit, King's College Hospital, London, England. Eight women with a subseptate uterus, 20 women with a history of unexplained recurrent first trimester miscarriage and 16 fertile controls had uterine cavity flushing, for glycodelin concentration, done 7 days after the luteinising hormone surge. RESULTS Glycodelin concentrations in uterine flushing obtained from women with subseptate uteri (n=8) (median 32.9 ng/ml, range 17.1-52.4 ng/ml) and recurrent miscarriage (n=20) (median 26.8 ng/ml, range 9.7-78.5 ng/ml) were significantly lower than in the control group (n=16) (median 67.7 ng/ml, range 59.0-77.6 ng/ml) (chi(2)=19.565, p<0.001). CONCLUSION Peri-implantation levels of glycodelin are lower in women at high risk of early pregnancy failure.

Abstract
OBJECTIVE To determine the intraobserver and interobserver reproducibility of measurement of the percentage of protrusion of submucous fibroids into the uterine cavity using three-dimensional saline contrast sonohysterography (3D-SCSH). METHODS Women diagnosed with submucous uterine fibroids on B-mode two-dimensional (2D) ultrasound scan were invited to join the study and 3D-SCSH was carried out. 3D volume datasets were stored digitally and were examined later using the technique of planar reformatted sections. The reproducibilities of the measurement of fibroid diameter and protrusion ratio into the uterine cavity (ratio of the size of the segment of the fibroid protruding into the cavity to the total diameter of the fibroid) were examined by two independent observers who were unaware of the initial 2D scan findings. Interobserver reproducibility was assessed by calculating the difference between measurements taken by the two operators (limits of agreement) and interclass correlation coefficient. Intraobserver repeatability was assessed by calculating the difference between two measurements for each variable (limits of agreement) and further expressed as an intraclass correlation coefficient. RESULTS Thirty-three 3D ultrasound volumes were examined. There was a good agreement between the observers in classifying the fibroids as greater or less than 50% confined to the myometrium (Cohen's kappa 0.81). There was no bias in measurements for both variables either between observers or with repeated measurements by each observer. For fibroid diameter and protrusion ratio the inter- and intraclass correlation coefficients were high (0.984-0.995), with narrow limits of agreement. CONCLUSION 3D-SCSH is a reproducible method for the quantification of the percentage of a submucous fibroid protruding into the uterine cavity.

Abstract
BACKGROUND The aim of this study was to examine the value of various ultrasound and biochemical parameters for the prediction of successful expectant management of miscarriage. METHODS This was a prospective observational study. Clinically stable women with an ultrasound diagnosis of miscarriage were offered expectant management. In all cases, gestational age, size of retained products of conception, serum HCG, progesterone, 17-hydroxyprogesterone, insulin growth factor-binding protein 1 (IGFBP-1), inhibin A and inhibin pro alpha-C RI levels were recorded. Follow-up continued until resolution of the pregnancy. Clinical data, ultrasound findings and biochemical markers were analysed using univariate analysis and decision tree analysis. RESULTS Fifty-four women underwent expectant management of miscarriage. Thirty-seven (69%) had successful expectant management and 17 (31%) required surgery. The size of retained products, serum HCG, progesterone, inhibin A and inhibin pro alpha-C RI were all significantly different in those pregnancies that resolved spontaneously (P<0.05). Serum inhibin A was the best predictor of a complete miscarriage. CONCLUSION This study shows that novel biochemical markers may be used to predict the likelihood of successful expectant management of miscarriage.

Abstract
BACKGROUND The purpose of this study was to compare three-dimensional saline infusion sonohysterography (3D SIS) and diagnostic hysteroscopy for the diagnosis and classification of submucous uterine fibroids. METHODS This was a prospective double-blind study of 49 women who presented with a history of menorrhagia, diagnosed on non-enhanced two-dimensional ultrasonography with submucous fibroids. Fibroids were classified on 3D SIS according to the proportion of fibroid contained within the endometrial cavity, using the European Society of Hysteroscopy Classification of Submucous Fibroids. These results were then compared with the findings at diagnostic hysteroscopy. RESULTS A total of 61 submucous fibroids was identified in 49 symptomatic women. Diagnostic hysteroscopy confirmed these findings in all cases. There was agreement between the two methods in 11/12 cases of Type 0 fibroids (92%), 34/37 (92%) of Type I fibroids and 9/12 (75%) of Type II fibroids. The overall level of agreement was good with a kappa value of 0.80. CONCLUSIONS There is a good overall agreement between 3D SIS and diagnostic hysteroscopy in classification of submucous fibroids. Agreement is better in cases where a greater proportion of the fibroid is contained within the uterine cavity.

Abstract
OBJECTIVE To establish whether a decision tree based on a combination of clinical, morphological and biochemical parameters could be constructed to help in the selection of women with tubal ectopic pregnancies for expectant management. METHODS This was a prospective observational study in a tertiary referral early pregnancy unit in an inner city teaching hospital. The study group consisted of 179 women with ultrasound diagnosis of ectopic pregnancy. Demographic, clinical and ultrasound data were recorded in each case at the initial visit. In addition all women had a blood sample taken for the measurements of serum beta-human chorionic gonadotropin (beta-hCG) and progesterone. Clinically stable women with non-viable pregnancies and no signs of hematoperitoneum were managed expectantly on an outpatient basis until their serum beta-hCG declined to <20 IU/L. Women who developed pelvic pain during follow-up and those with non-declining serum beta-hCG were offered surgery. RESULTS A total of 107/179 (59.8%) tubal ectopics were considered suitable for expectant management. Ectopic pregnancy resolved spontaneously in 75/107 (70%) women, which was 41.9% of the total number of tubal ectopics. Maternal age, initial serum beta-hCG and progesterone were all significantly different in pregnancies that resolved spontaneously compared to those requiring surgery (P < 0.05). Initial serum beta-hCG level was the best predictor of the outcome of expectant management. These differences enabled a construction of a four-level decision tree to estimate the likelihood of successful expectant management. CONCLUSIONS There are significant differences in demographic, ultrasound and biochemical findings between spontaneously resolving ectopics and those requiring treatment. Decision tree analysis may be used as a guide to estimate the probability of successful expectant management in individual cases.

Abstract
OBJECTIVE The aim of the study was to evaluate whether the presence of normal ovarian tissue adjacent to an adnexal tumor (the 'ovarian crescent sign') could assist in the preoperative differential diagnosis of adnexal lesions. METHODS This was a prospective observational study including 100 women with a preoperative diagnosis of an adnexal mass. Demographic and biochemical data were collected and all women underwent a detailed transvaginal ultrasound scan. Tumor volume, morphological characteristics and Doppler features were recorded in each case. In addition, the tissue adjacent to the cyst was systematically examined for the presence of normal ovarian tissue. All the findings were compared to the final histological diagnosis. RESULTS Sixty-seven (67%) of the cysts removed were benign, nine (9%) were borderline and 24 (24%) women had invasive malignant lesions. Normal ovarian tissue was seen in 58/76 (76%) women with non-invasive lesions, and in one woman (4%) with an invasive malignancy. In the absence of normal ovarian tissue, ovarian cancer was diagnosed with a sensitivity of 96% and specificity of 76%. CONCLUSION The presence of normal ovarian tissue adjacent to an ovarian cyst is a useful morphological feature that may be used to help exclude an invasive ovarian malignancy in women with adnexal masses detected on ultrasound scan.

Abstract
OBJECTIVE To examine the reproducibility of the diagnosis of congenital uterine anomalies and the repeatability of measurements of uterine cavity dimensions using three-dimensional (3D) ultrasound. METHODS The reproducibility of diagnosis of congenital uterine anomalies was examined by re-slicing stored 3D ultrasound volumes. Each data set was evaluated by two independent observers. Assessment of uterine morphology was performed in a standardized plane, with the interstitial portions of the Fallopian tubes used as reference points. Additionally, in 35 cases of congenital uterine anomalies the width of the uterine cavity (W), fundal distortion (F) and the length of unaffected uterine cavity (C) were measured. Intraobserver and interobserver variabilities were evaluated by each observer performing all three measurements twice. RESULTS Eighty-three 3D ultrasound volumes were examined. Both operators classified 27 uteri as normal, 33 as arcuate, 19 as subseptate and three as unicornuate. A single case of uterine anomaly was described as arcuate uterus by one operator and subseptate by another (kappa 0.97). The intraobserver variability for each of the three measurements (W, F and C) was satisfactory with limits of agreement ranging from +/-1.43 to +/-2.51 mm. The examination of the interobserver variability showed no significant differences between the two observers (F = 0.484, P > 0.05). CONCLUSION 3D ultrasound is a reproducible method for the diagnosis of congenital uterine anomalies and for the measurement of uterine cavity dimensions.

Abstract
OBJECTIVE To describe first-trimester ultrasound diagnosis and management of pregnancies implanted into uterine Cesarean section scars. METHODS All women referred for an ultrasound scan because of suspected early pregnancy complications were screened for pregnancies implanted into a previous Cesarean section scar. The management of Cesarean section scar pregnancies included transvaginal surgical evacuation, medical treatment with local injection of 25 mg methotrexate into the exocelomic cavity and expectant management. RESULTS Eighteen Cesarean section scar pregnancies were diagnosed in a 4-year period. The prevalence in the local population was 1 : 1800 pregnancies. Surgical treatment was used in eight women and it was successful in all cases. The respective success rates of medical treatment and expectant management were 5/7 (71%) and 1/3 (33%). Five women (28%) required blood transfusion and one woman (6%) had a hysterectomy. CONCLUSIONS Cesarean section scar pregnancies are more common than previously thought. When the diagnosis is made in the first trimester the prognosis is good and the risk of hysterectomy is relatively low.

Abstract
BACKGROUND The true impact of congenital uterine anomalies on reproductive outcomes is unknown. The aim of this study was to examine differences in the morphology of uterine anomalies found in women with and without a history of recurrent miscarriage. METHODS A total of 509 women with a history of unexplained recurrent miscarriage and 1976 low risk women were examined for the presence of congenital uterine anomalies by three-dimensional ultrasound. The anomalies were classified according to the American Fertility Society classification. In addition, the size of fundal distortion (F) and the length of the remaining uterine cavity (C) were measured to calculate a distortion ratio (F/F+C). The findings were compared with the measurements obtained in low risk women with an incidental finding of uterine anomaly. RESULTS In all, 121 anomalies were detected in the recurrent miscarriage group and 105 in low risk women. There was no significant difference in relative frequency of various anomalies or depth of fundal distortion between the two groups. However, with both arcuate and subseptate uteri, the length of remaining uterine cavity was significantly shorter (P < 0.01) and the distortion ratio was significantly higher (P < 0.01) in the recurrent miscarriage group. CONCLUSION The distortion of uterine anatomy is more severe in congenital anomalies, which are found in women with a history of recurrent first trimester miscarriage.

Abstract
OBJECTIVE To identify clinical, ultrasound and biochemical parameters that may allow prediction of pregnancy viability in women without a detectable embryo on ultrasound examination. METHODS This was a prospective observational study of pregnant women with an ultrasound finding of a gestational sac measuring < 20 mm mean diameter without a visible embryo. Women's age, menstrual dates, clinical symptoms (pain and bleeding), mean gestational sac diameter and measurements of serum beta-human chorionic gonadotropin and progesterone were recorded in all cases. All women were managed expectantly until the pregnancy viability was established conclusively based on clinical and ultrasound findings. All parameters were tested by univariate analysis and then analyzed in a stepwise procedure to form a logistic regression model for predicting pregnancy viability. RESULTS One hundred and eighteen (59%) women had a normal intrauterine pregnancy and 82 (41%) had a miscarriage. Stepwise analysis showed that three diagnostic parameters (maternal age, gestational sac diameter and serum progesterone) contributed significantly to the predictive power of the logistic model. With this model, at a cut-off value of 10% probability, the diagnosis of viable pregnancy was made with a sensitivity of 99.2% (95% CI, 95.8-99.97) and specificity of 70.7% (95% CI, 61.3-78.9). CONCLUSION The use of a logistic regression model allows prediction of pregnancy viability when an embryo cannot be visualized on ultrasound scan.

Abstract
Both chronic myeloid leukaemia (CML) and chronic lymphocytic leukaemia (CLL) are rare illnesses. Their co-existence has been previously reported, typically with CML following CLL. We report to our knowledge the first case of CLL developing some years after initial diagnosis of Philadelphia (Ph) chromosome positive CML. We provide molecular evidence that CLL arose in a Ph negative clone. The implications of the findings are discussed.

Abstract
OBJECTIVE To determine reproductive outcomes in women with congenital uterine anomalies detected incidentally by three-dimensional ultrasound. METHODS We studied 1089 women with no history of infertility or recurrent miscarriage who were seen for a transvaginal ultrasound scan. They were screened for uterine abnormalities using three-dimensional ultrasound. We determined prevalence of miscarriage and preterm labor in women with normal and abnormal uterine morphology. RESULTS We found that 983 women had a normally shaped uterine cavity, 72 an arcuate, 29 a subseptate, and five a bicornuate uterus. Women with a subseptate uterus had a significantly higher proportion of first-trimester loss (Zeta = 4.68, P <.01) compared with women with a normal uterus. Women with an arcuate uterus had a significantly greater proportion of second-trimester loss (Zeta = 5.76, P <.01) and preterm labor (Zeta = 4.1, P <.01). There were no other significant differences in pregnancy outcomes between women with normal and abnormal uterine morphology. CONCLUSION This study shows the potential value of three-dimensional ultrasound and confirmed that women with congenital uterine anomalies were more likely to have adverse pregnancy outcomes than women with a normal uterus.
