Randomized trial of screening for preterm birth in low-risk women - the preterm birth screening study. Am J Obstet Gynecol MFM 2024; 6:101267. [PMID: 38642994 DOI: 10.1016/j.ajogmf.2023.101267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/12/2023] [Accepted: 12/14/2023] [Indexed: 04/22/2024]
Abstract
BACKGROUND Preterm birth is a major cause of perinatal morbidity and mortality. It is unclear whether the introduction of a universal transvaginal ultrasound cervical length screening program in women at low risk for preterm delivery is associated with a reduction in the frequency of preterm birth. OBJECTIVE To test the hypothesis that the introduction of a midtrimester universal transvaginal ultrasound cervical length screening program in asymptomatic singleton pregnancies without prior preterm delivery would reduce the rate of preterm birth at <37 weeks of gestation. STUDY DESIGN This study was a multicenter nonblinded randomized trial of screening of asymptomatic singleton pregnancies without prior spontaneous preterm birth, who were randomized to either cervical length screening program (ie, intervention group) or no screening (ie, control group). Participants were randomized at the time of their routine anatomy scan between 18 0/7 and 23 6/7 weeks of gestation. Women randomized in the screening group received cervical length measurement. Those who were found to have cervical length ≤25 mm were offered 200 mg vaginal progesterone daily along with cervical pessary. The primary outcome was preterm birth at <37 weeks. The risk of primary outcome was quantified by the relative risk with 95% confidence interval, and was based on the intention-to-screen principle. RESULTS A total of 1334 asymptomatic women with singleton pregnancies and without prior preterm birth, were included in the trial. Out of the 675 women randomized in the transvaginal ultrasound cervical length screening group, 13 (1.9%) were found to have transvaginal ultrasound cervical length ≤25 mm during the screening. Preterm birth at <37 weeks of gestation occurred in 48 women in the transvaginal ultrasound cervical length screening group (7.5%), and 54 women in the control group (8.7%) (relative risk, 0.86; 95% confidence interval, 0.59-1.25). Women randomized in the transvaginal ultrasound cervical length screening group had no significant differences in the incidence of preterm birth at less than 34, 32, 30, 28, and 24 weeks of gestation. CONCLUSION The introduction of a universal transvaginal ultrasound cervical length screening program at 18 0/6 to 23 6/7 weeks of gestation in singleton pregnancies without prior spontaneous preterm birth, with treatment for those with cervical length ≤25 mm, did not result in significant lower incidence of preterm delivery than the incidence without the screening program.

Developing DPYD Genotyping Method for Personalized Fluoropyrimidines Therapy. J Appl Lab Med 2024; 9:295-304. [PMID: 38084968 DOI: 10.1093/jalm/jfad092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Accepted: 08/15/2023] [Indexed: 03/02/2024]
Abstract
BACKGROUND Fluoropyrimidine drugs are widely used in chemotherapy to treat solid tumors. However, severe toxicity has been reported in 10% to 40% of patients. The DPYD gene encodes the rate-limiting enzyme dihydropyrimidine dehydrogenase responsible for fluoropyrimidine catabolism. The DPYD variants resulting in decreased or no enzyme activity are associated with increased risk of fluoropyrimidine toxicity. This study aims to develop a pharmacogenetic test for screening DPYD variants to guide fluoropyrimidine therapy. METHODS A multiplex allele-specific polymerase chain reaction (AS-PCR) assay, followed by capillary electrophoresis, was developed to detect 5 common DPYD variants (c.557A > G, c.1129-5923C > G, c.1679T > G, c.1905 + 1G > A, and c.2846A > T). Deidentified population samples were used for screening positive controls and optimizing assay conditions. Proficiency testing samples with known genotypes were analyzed for test validation. All variants detected were confirmed by Sanger sequencing. RESULTS From the deidentified population samples, 5 samples were heterozygous for c.557A > G, 2 samples were heterozygous for c.1129-5923C > G (HapB3), and 1 sample was heterozygous for c.2846A > T. The 20 proficiency samples matched with their assigned genotypes, including 13 wild-type samples, 3 samples heterozygous for c.1679T > G, 2 samples heterozygous for c.1905 + 1G > A, and 2 samples heterozygous for c.2846A > T. One of the 3 patient samples was heterozygous for c.1129-5923C > G (HapB3). All the variants detected by the multiplex AS-PCR assay were concordant with Sanger sequencing results. CONCLUSIONS A robust multiplex AS-PCR assay was developed to rapidly detect 5 variants in the DPYD gene. It can be used for screening DPYD variants to identify patients with increased risk of toxicity when prescribed fluoropyrimidine therapy.

Hysteroscopic Endometrial Ablation: From Indications to Instrumentation and Techniques-A Call to Action. Diagnostics (Basel) 2023; 13:diagnostics13030339. [PMID: 36766443 PMCID: PMC9914843 DOI: 10.3390/diagnostics13030339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 01/15/2023] [Accepted: 01/16/2023] [Indexed: 01/19/2023] Open
Abstract
The development of minimally invasive techniques has led to the creation of innovative alternatives in cases where traditional methods are not applicable. In modern gynecology, hysteroscopy has become the gold standard for the evaluation and treatment of intrauterine pathology. Endometrial ablation (EA) is a procedure that uses different types of energy to destroy the endometrium and is currently used as an alternative technique in cases of heavy menstrual bleeding when medical treatment has failed and uterine preservation is desired. The aim of this review was to evaluate the feasibility, safety, and clinical outcomes of hysteroscopic EA as an alternative in patients with abnormal uterine bleeding. A detailed computerized search of the literature was performed in the main electronic databases (MEDLINE, EMBASE, Web of Science, PubMed, and Cochrane Library), from 1994 to June 2022, to evaluate the outcomes in patients with abnormal uterine bleeding (AUB) undergoing EA using hysteroscopic and non-hysteroscopic techniques. Only scientific publications in English were included. Twelve articles on the current use of endometrial ablation were included. Data on patient symptoms, tools used for EA, primary outcomes, and adverse events were recorded. EA should be considered an effective and safe approach in the management of patients with abnormal uterine bleeding caused by benign pathology, in whom medical treatment has failed or is contraindicated. Due to the lack of evidence, it would be interesting to determine whether EA would also have a role in the treatment of women with premalignant lesions, avoiding invasive surgical procedures or medical treatment in those patients for whom hysterectomy or the use of hormonal treatment is contraindicated.

Abstract
OBJECTIVE To compare maternal blood loss with immediate cord clamping versus delayed cord clamping in women undergoing spontaneous vaginal delivery at term. METHODS Parallel group non-blinded randomized trial conducted at a single center in Italy. Women with singleton gestations who underwent spontaneous vaginal delivery at term were eligible and were randomized in a 1:1 ratio to either immediate or delayed cord clamping. In the immediate cord clamping group, cord clamping was within 15 s after birth. In the delayed cord clamping group, cord clamping was after more than 60 s, or when the cord had stopped pulsing. The primary outcome was change in maternal hemoglobin level from the day of delivery to day one after delivery. RESULTS A total of 122 participants were enrolled in the trial. There were no significant differences in maternal blood loss as assessed by comparing the decrease in maternal hemoglobin level (mean difference - 0.10 g/dl, 95% confidence interval - 0.28 to 0.08) between the two groups. The mean hemoglobin level at postdelivery day 1 was 11.0 ± 1.5 g/dl in the delayed group and 11.3 ± 1.6 g/dl in the immediate group. CONCLUSIONS Delayed umbilical cord clamping, compared with immediate umbilical cord clamping, resulted in no significant change in maternal hemoglobin level 1 day after delivery. TRIAL REGISTRATION Clinicaltrials.gov NCT04353544.

Abstract
PURPOSE The Cannabis Consultation Service (CCS) is an innovative pharmacist-led resource at the Sunnybrook Odette Cancer Centre. Its mandate is to provide education and guide patients through access and appropriate use of high-quality plant-derived cannabinoids (PDCs). Our objective was to describe the CCS, explain its processes, and characterize patient disposition with respect to use of PDCs. METHODS We retrospectively reviewed the charts of patients referred to the CCS from July 13, 2020, to March 05, 2021. We used descriptive statistics to report on the patient population and service metrics. RESULTS During the 34-week period, 96 patients accessed the CCS (median age, 61 years). The top reasons for CCS consultation were management of cancer pain, insomnia, and general interest. Medical cannabis was supported as an option in 44/96 patients. Reasons for not supporting PDC use included lack of indication, potential drug interaction/contraindication, or requiring treatment with first-line therapy. Of the 40 patients requiring a medical document, 22 initiated therapy. The most common product used was a 2:50 THC:CBD (Tetrahydrocannabinol:Cannabidiol) cannabis oil. At the date of last contact, few patients remained on therapy because of lack of benefit, patient choice, and/or hesitancy. CONCLUSION Despite patients with cancer having interest in seeking PDCs for symptom management, only a few initiated and continued therapy. Pharmacists have an opportunity to advise patients and the oncology team on the risks and benefits of PDCs. These results can be used to support the development of medical cannabis programs by oncology centers and focus future research priorities.

Second stimulation in the same ovarian cycle: an option to fully-personalize the treatment in poor prognosis patients undergoing PGT-A. J Assist Reprod Genet 2022; 39:663-673. [PMID: 35128583 PMCID: PMC8995212 DOI: 10.1007/s10815-022-02409-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 01/17/2022] [Indexed: 10/19/2022] Open
Abstract
PURPOSE Our primary objective was to assess whether immediately undergoing a second stimulation in the same ovarian cycle (DuoStim) for advanced-maternal-age and/or poor-ovarian-reserve (AMA/POR) patients obtaining ≤ 3 blastocysts for preimplantation-genetic-testing-for-aneuploidies (PGT-A) is more efficient than the conventional-approach. METHODS All AMA/POR patients obtaining ≤ 3 blastocysts after conventional-stimulation between 2017 and 2019 were proposed DuoStim, and 143 couples accepted (DuoStim-group) and were matched for the main confounders to 143 couples who did not accept (conventional-group). GnRH-antagonist protocol with recombinant-gonadotrophins and agonist trigger, intra-cytoplasmatic-sperm-injection (ICSI) with ejaculated sperm, PGT-A and vitrified-warmed euploid single-blastocyst-transfer(s) were performed. The primary outcome was the cumulative-live-birth-delivery-rate per intention-to-treat (CLBdR per ITT) within 1 year. If not delivering, the conventional-group had 1 year to undergo another conventional-stimulation. A cost-effectiveness analysis was also conducted. RESULTS The CLBdR was 10.5% in the conventional-group after the first attempt. Only 12 of the 128 non-pregnant patients returned (165 ± 95 days later; drop-out = 116/128,90.6%), and 3 delivered. Thus, the 1-year CLBdR was 12.6% (N = 18/143). In the DuoStim-group, the CLBdR was 24.5% (N = 35/143; p = 0.01), 2 women delivered twice and 13 patients have other euploid blastocysts after a LB (0 and 2 in the conventional-group). DuoStim resulted in an incremental-cost-effectiveness-ratio of 23,303€. DuoStim was costlier and more effective in 98.7% of the 1000 pseudo-replicates generated through bootstrapping, and the cost-effectiveness acceptability curves unveiled that DuoStim would be more cost-effective than the conventional-approach at a willingness-to-pay threshold of 23,100€. CONCLUSIONS During PGT-A treatments in AMA/POR women, DuoStim can be suggested in progress to rescue poor blastocyst yields after conventional-stimulation. It might indeed prevent drop-out or further aging between attempts.

Abstract
OBJECTIVE To describe clinical and demographic characteristics, ultrasound appearance, and hysteroscopic outcomes of patients with endometrial osseous metaplasia. STUDY DESIGN We conducted a multicenter retrospective study. We retrospectively reviewed the medical records of all consecutive patients who were referred for hysteroscopy at fourteen institutions in Venezuela, Spain, Morocco, India, Ukraine, Argentina, the United States, and Italy between 1994 and 2018. We identified and included all patients who had a diagnosis of osseous metaplasia at the pathologic report, and data were retrieved from the medical records. RESULTS Between January 1st, 1994, and December 31st, 2018, 63 patients out of a total of 419,673 women who underwent hysteroscopy had a diagnosis of osseous metaplasia (0.015%). Most patients were 31-40 years old (53.7%), were Caucasian or Hispanic (95.5%), and had at least one previous pregnancy (86.9%). Forty-one out of 63 patients (65.1%) had at least one miscarriage before the index hysteroscopy. Dysmenorrhea, abnormal uterine bleeding, and infertility were reported by 34.9%, 27.0%, and 23.8% of patients. 14.3% of women were asymptomatic. Preoperative transvaginal ultrasound was available and identified a hyperechoic area of variable size with posterior acoustic shadowing in all cases. Hysteroscopy was successful without complications in all 63 cases. Follow-up data were available in 30.2% of patients: 69.2% of patients were infertile, and 44.4% of them conceived and achieved a live birth; all other symptoms improved after hysteroscopic treatment in all patients. CONCLUSIONS Osseous metaplasia appears associated with multiple unspecific gynecologic symptoms without the predominant role of infertility, as previously suggested. Although endometrial osseous metaplasia is rare, gynecologists should consider this pathologic condition when the characteristic ultrasound appearance is detected, being hysteroscopic treatment effective.

Abstract
BACKGROUND The recent literature on intrahepatic cholestasis of pregnancy raises questions on the best management of such a disease. Improved evidence might be achieved by meta-analyses. AIM Providing data for allowing individual patients meta-analyses and aggregate data meta-analyses. METHODS Data were collected retrospectively at the Fabia Mater Hospital of Rome (Italy), between 2013 and 2018. Several variables were collected and analyzed according to low-level bile acid (less than 40 μmol/L) and high-level bile acid (at least 40 μmol/L). Eighty-three cases of pregnancy cholestasis, diagnosed according to itching symptoms and excluding bile diseases, were collected and analyzed, both descriptively and inferentially. CONCLUSION The analyzed data do not provide significant evidence supporting the use of ursodeoxycholic acid to prevent composite adverse fetal outcomes but they can be included in further meta-analyses.

Abstract
AIM Assessing awareness of Italian low-risk pregnant patients on low-risk pregnancy care and what do they feel about their own pregnancy. METHODS A questionnaire was administered to 382 low-risk pregnant women. This questionnaire assessed general knowledge of low-risk pregnancy, low-risk pregnancy care, and how much patients rated ten topics of low-risk pregnancy care. It would be expected that the knowledge of each topic would associates with the patient's perceived importance of that topic. RESULTS Poor knowledge of pregnancy care was proven. Patients seem to incorrectly overrate vaginal examinations and obstetric and gynecologist-led care, while they attribute appropriate importance to midwife-led care. The more examinations performed (vaginal examinations, sonographic checks, cardiotocographies), the higher their rating. CONCLUSIONS In Italy, expectations of pregnant women about their own pregnancy are incorrectly trusted in the obstetrics and gynecologists. Both poor knowledge of pregnancy care and cultural perspectives on the birth process amongst Italian people explain the finding. Referring low-risk pregnant women to midwives would help them to rate more the care than the caregiver.

Abstract
Objective: Immersion in water during labor and delivery has been studied as an alternative form of obstetric care. The aim of this study was to evaluate obstetrics and neonatal outcomes of women intending to use immersion in water for labor and delivery. Methods: This was a retrospective observational study conducted at a single center in Italy from January 2004 to January 2016. The clinical records of pregnant women intending to use immersion in water for labor and delivery were collected in a dedicated database and included in the study. Only the women who underwent immersion in water starting from the first stage of labor were included in the study. Inclusion criteria were women with uncomplicated singleton gestations and cephalic presentation at or later than 37 weeks of gestation, and with spontaneous onset of labor. The primary outcome of the study was the percentage of women who had both labor and delivery in water. Results: 389 women met the inclusion criteria and were included in the study. 256 (66%) were nulliparous, and 133 (34%) were multiparous. Out of the 389 women intending to use immersion in water for labor and delivery, 278 (71.5%) had labor and delivery in the water, 31 (8.0%) labor in water and delivery on land, and 80 (20.5%) had the first stage of labor in water, and the second stage and delivery on land. The incidence of perineal lacerations was 61.4%. Conclusion: The vast majority of the women who set out to labor and delivery in water achieve their aim.

Abstract
Objective: Episiotomy is associated with an increased risk of postpartum pain, bleeding, and dyspareunia. The hypothesis of this trial was that in women with singleton pregnancy, and spontaneous labor at term, use of calendula ointment would reduce pain after episiotomy.Methods: This was a single-center parallel group randomized trial of women with singleton pregnancies and spontaneous labor at term who were randomized to either use of calendula ointment (i.e. intervention group) or standard care (i.e. control group) after episiotomy. Eligible women were those with singleton gestations in spontaneous labor and vertex presentation at term. Women with premature rupture of membranes were excluded from the study. Women in the intervention group were recommended use of calendula ointment 4 h after the episiotomy and then every 8 h for 10 days. The primary outcome was the pain level. Pain level was self-reported and recorded using the verbal rating scale (VRS). The effect of the calendula ointment was quantified as mean difference (MD) with 95% confidence interval (CI).Results: During the study, 100 women agreed to take part in the study, underwent randomization, and were enrolled in this trial. Of the 100 randomized women, 50 were randomized to the calendula ointment group, and 50 to the control group. No women were excluded after randomization or lost to follow up.Women who received calendula ointment after episiotomy compared to standard care had a significantly lower pain level starting from day two and during all the follow-up. Calendula ointment also improve wound healing in terms of redness and edema.Conclusions: Use of calendula ointment significantly reduce pain after episiotomy.

Abstract
INTRODUCTION Microglandular adenosis (MGA) is a rare benign proliferative lesion lacking a myoepithelial cell layer; 27% of all reported cases have progressed to invasive carcinoma. Salivary gland-type carcinomas of the breast are also uncommon, representing 2% of all breast cancers. This wide spectrum of neoplasms tends to be triple negative and generally has an excellent prognosis. Given the rarity of salivary gland-type carcinomas of the breast arising from MGA, there are few reports of these cases in literature. As such, there is uncertainty regarding their diagnosis and treatment strategies. PRESENTATION OF CASE We report the rare case of a 66-year-old woman who presented with a triple negative, invasive carcinoma with salivary gland-type features, arising from MGA. The patient underwent mastectomy with sentinel lymph node biopsy, followed by Taxotere and Cyclophosphamide (TC) chemotherapy and 50 Gy in 25 fractions of radiation to her chest wall. We reviewed the available literature on salivary gland-type breast carcinomas arising from MGA. DISCUSSION Despite the generally unfavourable characteristics associated with carcinoma arising in microglandular adenosis (MGACA), most patients with MGACA have favourable outcomes. CONCLUSIONS The findings of the present case and reviewed cases are consistent with the literature on MGA, atypical MGA (AMGA), and MGACA. Future study of this rare entity is warranted to establish a consensus surrounding its clinical significance and treatment methods.

Abstract
Inadequate uterine receptivity is responsible for two-third of implanting failures. Aim of the study was to investigate the role of epithelial adherence and tight-junction molecules expressed by human endometrium in predicting womens' fertility outcome. A total of 76 consecutive women, including 24 fertile (G1), 40 primary infertile (G2), and 12 recurrent pregnancy loss (RPL, G3) women, who underwent diagnostic hysteroscopy plus endometrial biopsy between 2005 and 2016 at the Gynecology Division of Sant'Andrea Hospital, Sapienza University of Rome, in Italy, were retrospectively identified and included into the study. Endometrial biopsies were assessed for the immunohistochemical expression of beta-catenin (β-catenin), E-cadherin and K-cadherin biomarkers. Expression profiles were compared between the three groups of patients and were correlated with patients' fertility outcome. In infertile patients there was a significant lower endometrial expression of β-catenin (p = .001), E-cadherin (p = .001) and K-cadherin (p = .002), compared to the fertile ones. Furthermore, β-catenin and E-cadherin intensity gradients of expression at glandular level were found totally reversed in infertile patients. Significant lower expression levels of K-catenin (p = .016) and E-cadherin (p < .0001) at glandular level were found in RPL patients. Results showed that the low endometrial expression of β-catenin, E-cadherin and K-cadherin were associated to fertility-related problems, such as primary intertility and RPL.

[PMID: 30914327 DOI: 10.1016/j.jmig.2019.03.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 02/28/2019] [Accepted: 03/19/2019] [Indexed: 10/27/2022]
Abstract
STUDY OBJECTIVES To describe and demonstrate a technique for laparoscopic removal of a perforating intrauterine device (IUD) during pregnancy, and to provide tips to facilitate safe laparoscopic surgery during pregnancy. DESIGN Video presentation of the technique for laparoscopic removal of a perforating IUD in a pregnant woman. SETTING Department of Neuroscience, Reproductive Sciences, and Dentistry, University of Naples Federico II, Naples, Italy. INTERVENTION A 30-year-old woman, gravida 3, para 2, with a copper T IUD (Nova T 380; Bayer, Leverkusen, Germany) perforating the left adnexa presented to the emergency room complaining of left lower quadrant pain. The patient had the IUD inserted by her gynecologist 3 months before the onset of the symptoms. Ultrasound revealed a 6-week intrauterine pregnancy with the presence of fetal cardiac activity along with the IUD perforating the left adnexa. The patient returned at 11 weeks of gestation complaining of worsening abdominal pain and excruciating left lower quadrant pain. She was scheduled for laparoscopic excision of the perforating IUD [1-3]. Considering her pregnancy, laparoscopy under regional anesthesia was performed in the minimal Trendelenburg position at 12 degrees, through open laparoscopic access [4]. Intra-abdominal pressure of 8 mmHg and ultrasound energy to cut and coagulate, avoiding monopolar/bipolar energy owing to the presence of a copper IUD, were used. The IUD and tube were extracted in an endobag through umbilical access, under a 5-mm, 0-degree telescope in left lateral access [5]. The procedure was carried out uneventfully, and the IUD was removed. Fetal viability was confirmed after the procedure. At the time of this report, the patient was in the 23rd week of gestation, and the pregnancy was progressing without any problems. CONCLUSION Laparoscopic removal of perforated IUD during pregnancy under regional anesthesia is a feasible and safe option that should be considered when needed.

Effectiveness of Hysteroscopic Techniques for Endometrial Polyp Removal: The Italian Multicenter Trial. J Minim Invasive Gynecol 2018; 26:1169-1176. [PMID: 30528831 DOI: 10.1016/j.jmig.2018.12.002] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 12/03/2018] [Accepted: 12/05/2018] [Indexed: 10/27/2022]
Abstract
STUDY OBJECTIVE To compare the effectiveness and safety of different techniques of hysteroscopic polypectomy. DESIGN Multicenter, prospective observational trial (Canadian Task Force classification II-2). SETTING Nineteen Italian gynecologic departments (university-affiliated or public hospitals). PATIENTS Consecutive patients suffering from endometrial polyps (EPs). INTERVENTIONS Hysteroscopic polypectomy, as performed through different techniques. MEASUREMENTS AND MAIN RESULTS Included in the study were 1404 patients (with 1825 EPs). The setting was an ambulatory care unit in 40.38% of the cases (567 women), of whom 97.7% (554) did not require analgesia/anesthesia. In the remaining 59.62% of women (837 women), the procedures were performed in an operating room under mild sedation, local or general anesthesia. Minor complications occurred in 32 patients (2.27%), without significant differences between the techniques used (p = ns). Uterine perforation occurred in 14 cases, all performed in the operating room with some kind of anesthesia, only 1 with a vaginoscopic technique and the remaining during blind dilatation (odds ratio [OR], 19.98; 95% confidence interval [CI], 1.19-335.79; p = .04). An incomplete removal of EPs was documented in 39 patients. Logistic regression analysis showed that a higher risk of residual EPs was associated with the use of a fiber-based 3.5-mm hysteroscope (OR, 6.78; 95% CI, 2.97-15.52; p <.001), the outpatient setting (OR, 2.17; 95% CI, 1.14-4.14; p = .019), and EPs located at the tubal corner (OR, 1.98; 95% CI, 1.03-2.79; p = .039). No association between incomplete EP removal and EP size or number was recorded (p = ns), as well as with the other variables evaluated. CONCLUSION Outpatient polypectomy was associated with a minimal but significantly higher risk of residual EPs in comparison with inpatient polypectomy. Conversely, inpatient polypectomy was associated with a considerably higher risk of uterine perforation and penetration in comparison with office hysteroscopy. Because of lower intraoperative risks and higher cost-effectiveness, office hysteroscopy may be considered, whenever possible, as the gold standard technique for removing EPs.

Synergistic antiproliferative and differentiating effect of 2,4-monofurfurylidene-tetra-O-methylsorbitol and 4,6-dimethyl-2-(3,4,5-trimethoxyphenylamino)pyrimidine on primary and immortalized keratinocytes. Biomed Pharmacother 2018; 107:155-167. [PMID: 30086462 DOI: 10.1016/j.biopha.2018.07.174] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2018] [Revised: 07/31/2018] [Accepted: 07/31/2018] [Indexed: 10/28/2022] Open
Abstract
Psoriasis is one of the most common chronic autoinflammatory skin disease, associated with hyperproliferation and abnormal differentiation of keratinocytes, inflammation, and angiogenesis. The available treatments for psoriasis are not curative and may have numerous side effects, and topical administration is preferred over systemic therapy due to the reduced systemic burden of the drug. Thus, novel and more efficacious formulations of anti-inflammatory and/or differentiating compounds for topical application could be very useful for the disease management and for improving the quality of life of the patients. Here we evaluated the potential as anti-psoriatic of an equimolar mixture of two compounds, 2,4-Monofurfurylidene-tetra-O-methylsorbitol (Compound A) and 4,6-dimethyl-2-(3,4,5-trimethoxyphenylamino)pyrimidine (Compound B), that, used individually, are known to possess immunomodulating properties (Compound A) and keratolitic and anti-inflammatory activity (Compound B). Human immortalized keratinocyte cell line (HaCaT cells) and primary human keratinocyte cells from adult donor (HEKa) were used as in vitro experimental models. We show that the mix A + B exhibits antiproliferative activity and induces terminal differentiation more efficiently than compounds A and B used individually. We confirm that the compound B is the active ingredient of the mixture and the mainly responsible for anti-psoriatic activity, but the mix A + B is more effective and possesses lower cytotoxicity than the compound B alone. This could be ascribable to the association with compound A, that is known to possess, in addition to the immunomodulating ability, antioxidant and antiradical action. Our results indicate that mix A + B could be a suitable candidate for a new cosmeceutical formulation for topical treatment of psoriasis.

The Conserved Sonic Hedgehog Limb Enhancer Consists of Discrete Functional Elements that Regulate Precise Spatial Expression. Cell Rep 2018; 20:1396-1408. [PMID: 28793263 PMCID: PMC5561167 DOI: 10.1016/j.celrep.2017.07.037] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2016] [Revised: 05/17/2017] [Accepted: 07/13/2017] [Indexed: 12/21/2022] Open
Abstract
Expression of sonic hedgehog (Shh) in the limb bud is regulated by an enhancer called the zone of polarizing activity regulatory sequence (ZRS), which, in evolution, belongs to an ancient group of highly conserved cis regulators found in all classes of vertebrates. Here, we examined the endogenous ZRS in mice, using genome editing to establish the relationship between enhancer composition and embryonic phenotype. We show that enhancer activity is a consolidation of distinct activity domains. Spatial restriction of Shh expression is mediated by a discrete repressor module, whereas levels of gene expression are controlled by large overlapping domains containing varying numbers of HOXD binding sites. The number of HOXD binding sites regulates expression levels incrementally. Substantial portions of conserved sequence are dispensable, indicating the presence of sequence redundancy. We propose a collective model for enhancer activity in which function is an integration of discrete expression activities and redundant components that drive robust expression. The ancient vertebrate enhancer, the ZRS, shows sequence plasticity Discrete regulatory activities are assigned to specific sites in the enhancer The number of HOXD binding sites determines the level of Shh expression Robust expression is a collective of regulatory and redundant information

A prospective cohort study of patient-reported vomiting, retching, nausea and antiemetic use during neoadjuvant long-course radiation therapy and concurrent 5-fluorouracil-based chemotherapy for rectal adenocarcinoma. Clin Transl Radiat Oncol 2018; 10:42-46. [PMID: 29682620 PMCID: PMC5909027 DOI: 10.1016/j.ctro.2018.04.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Revised: 03/29/2018] [Accepted: 04/03/2018] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND AND PURPOSE Antiemetic guidelines suggest daily prophylaxis with a serotonin3 receptor antagonist (5-HT3RA) as an option for patients receiving long-course neoadjuvant radiation therapy and concurrent 5-fluorouracil-based chemotherapy for rectal cancer, despite the risks that 5-HT3RA-induced constipation may pose. We explored the incidence of patient-reported vomiting, retching, nausea and antiemetic intake among patients in this setting to determine if these risks are justified. MATERIALS AND METHODS We carried out a single-centre non-randomised prospective cohort study of adult patients receiving long-course neoadjuvant radiation therapy and concurrent 5-fluorouracil-based chemotherapy for rectal adenocarcinoma. Patients recorded symptoms and medication intake daily until 7 days following treatment completion. RESULTS From 33 evaluable patients, we collected 1407 days of patient-reported data. Vomiting was reported by 7 patients (21%), retching by 5(15%) and nausea by 21(64%). No patients were administered prophylactic antiemetics. The median number of days with vomiting was 2, and the cumulative number of days for all affected patients was 22 (1.6% of 1407 evaluable days). There were no differences in PTV or small bowel loop V15Gy, V45Gy and V50Gy volumes between patients that did and did not vomit. CONCLUSIONS The cumulative incidence of days with vomiting was only 1.6%. 5-HT3RA prophylaxis during long-course neoadjuvant treatment seems unnecessary.

Fibroblast growth factors (FGFs) prime the limb specific Shh enhancer for chromatin changes that balance histone acetylation mediated by E26 transformation-specific (ETS) factors. eLife 2017; 6:28590.

Abstract
Sonic hedgehog (Shh) expression in the limb bud organizing centre called the zone of polarizing activity is regulated by the ZRS enhancer. Here, we examine in mouse and in a mouse limb-derived cell line the dynamic events that activate and restrict the spatial activity of the ZRS. Fibroblast growth factor (FGF) signalling in the distal limb primes the ZRS at early embryonic stages maintaining a poised, but inactive state broadly across the distal limb mesenchyme. The E26 transformation-specific transcription factor, ETV4, which is induced by FGF signalling and acts as a repressor of ZRS activity, interacts with the histone deacetylase HDAC2 and ensures that the poised ZRS remains transcriptionally inactive. Conversely, GABPα, an activator of the ZRS, recruits p300, which is associated with histone acetylation (H3K27ac) indicative of an active enhancer. Hence, the primed but inactive state of the ZRS is induced by FGF signalling and in combination with balanced histone modification events establishes the restricted, active enhancer responsible for patterning the limb bud during development. As an animal embryo develops, specific genes need to be switched on and off at the right time and place to ensure that the embryo’s tissues and organs form properly. Proteins called transcription factors control the activity of individual genes by binding to regions of DNA known as enhancers. Changes in the way DNA is packaged inside cells can affect the ability of transcription factors to access the enhancers, and therefore also influence when particular genes are switched on or off. Sonic hedgehog (or Shh for short) is a gene that helps to control various aspects of development including the formation of the limbs and brain. The limb forms from a structure in the embryo referred to as the limb bud. An enhancer called ZRS regulates the precise position within the limb bud where the Shh gene is active in a region designated as the “zone of polarizing activity”. Yet, it was not known how the enhancer is controlled to ensure this pattern is achieved. Peluso et al. investigated the events that lead to ZRS becoming active in mice embryos. The experiments show that the ZRS enhancer exists in three different states in cells across the limb bud: poised, active and inactive. The enhancer is poised in a broad region of the limb bud in cells that are potentially able to switch on the Shh gene. Proteins called fibroblast growth factors drive the enhancer to enter this poised state by altering the way the DNA containing the enhancer is packaged in the cell. Specific transcription factors are able to bind to the poised enhancer and it is the balance between these different transcription factors that activates the enhancer in the zone of polarizing activity. Furthermore in the region of the limb bud where the fibroblast growth factors are not present the ZRS is inactive. These findings show that fibroblast growth factors, in combination with other changes to the ZRS enhancer, restrict the area in which the enhancer is active to a particular region of the limb bud. Differences in enhancer elements are known to underlie a range of inherited characteristics and may influence whether an individual develops many common diseases. In the future, investigating how cells control the activity of enhancers may provide clues to identifying new targets for drugs to treat some of these diseases.

Abstract
Abstract
Background: Metastasis in ER-positive (+) breast cancer (BC) occurring years to decades after initial diagnosis presents a daunting challenge for clinical care and preclinical research due to limited known key players and experimental models. FOXA1 is a pioneer factor for ER-chromatin binding and function, and is highly expressed in ER+ BC metastases, yet the underlying mechanism is unclear. Tumor-secreted proteins play a crucial role in the reciprocal interplay between cancer cells and host microenvironmental factors at both primary and secondary sites. We hypothesized that high FOXA1 provokes an ER-dependent transcriptional program that includes a unique pro-tumorigenic secretome essential for promoting ER+ BC metastasis. Methods: A lentiviral doxycycline (Dox)-inducible FOXA1 overexpression vector and a dual luciferase/GFP (LG) tracking vector were integrated to construct a stable MCF7-LG/FOXA1 cell model. Ovariectomized nude mice bearing MCF7-LG/FOXA1 xenografts in the presence of exogenous estrogen (E2) were randomized to ± Dox, each with continued E2, E2 deprivation (ED), or tamoxifen (Tam). Survival surgery removing the therapy-naïve (E2 arm) and relapsed (ED/Tam arms) tumors was performed when tumors reached ∼1000 mm3. All mice then received ED/Tam 'adjuvant' therapy, with longitudinal luminescence imaging to monitor local/distant recurrences. Mice were or will be euthanized at the ethical end-point. Integrative bioinformatics was performed using RNA-seq and FOXA1/ER ChIP-seq data from our preclinical models to identify secretome targets for functional intervention. Times to tumor regression (TTR) and progression (TTP) were defined by when the tumor reached half or twice the volume at randomization. Results: Median (m) TTR was achieved in ED (31/34 days, -/+Dox, P = 0.184) but not in Tam groups — Tam delayed tumor growth but failed to prevent progression in all mice with mTTP of 94/93 days (-/+Dox, P = 0.517). Despite no difference in mTTP at Tam-/+Dox, a quarter of +Dox tumors (3/12) had volume doubled by day 11. No metastases were observed by imaging in any of the mice before surgery ('neoadjuvant' setting). Local relapse and lymph-node/lung metastases were detected after surgery ('adjuvant' setting). At day 90 in the adjuvant Tam group with previously relapsed tumors, +Dox mice succumbed to metastasis more often than -Dox mice (7/8 vs. 3/10, P = 0.023). Compared to the adjuvant Tam+Dox mice with previous therapy-naïve tumors, the Tam+Dox with previously relapsed tumors showed higher distant metastasis rate (7/8 vs. 5/14, P = 0.026). Analysis of the ED setting is pending due to late recurrence. Data integration and functional study revealed a set of cytokines, growth factors, and extracellular matrix components (including IL-8, CTGF, and LOX), regulated by FOXA1 often in conjunction with ER, that are highly involved in FOXA1-induced metastasis. Global secretome profiling by mass spectrometry and target validation are ongoing. Conclusions: FOXA1 overexpression increases metastatic potential in ER+ BC. We established a pertinent metastatic xenograft mouse model to characterize a pro-metastatic secretome with diagnostic and therapeutic potential for treating metastatic ER+ BC.

Abstract
STUDY QUESTION What is the recommended diagnostic work-up of female genital anomalies according to the European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) system? SUMMARY ANSWER The ESHRE/ESGE consensus for the diagnosis of female genital anomalies is presented. WHAT IS KNOWN ALREADY Accurate diagnosis of congenital anomalies still remains a clinical challenge because of the drawbacks of the previous classification systems and the non-systematic use of diagnostic methods with varying accuracy, some of them quite inaccurate. Currently, a wide range of non-invasive diagnostic procedures are available enriching the opportunity to accurately detect the anatomical status of the female genital tract, as well as a new objective and comprehensive classification system with well-described classes and sub-classes. STUDY DESIGN, SIZE, DURATION The ESHRE/ESGE CONgenital UTerine Anomalies (CONUTA) Working Group established an initiative with the goal of developing a consensus for the diagnosis of female genital anomalies. The CONUTA working group and imaging experts in the field have been appointed to run the project. PARTICIPANTS/MATERIALS, SETTING, METHODS The consensus is developed based on: (i) evaluation of the currently available diagnostic methods and, more specifically, of their characteristics with the use of the experts panel consensus method and of their diagnostic accuracy by performing a systematic review of evidence and (ii) consensus for the definition of where and how to measure uterine wall thickness and the recommendations for the diagnostic work-up of female genital anomalies, based on the results of the previous evaluation procedure, with the use of the experts panel consensus method. MAIN RESULTS AND THE ROLE OF CHANCE Uterine wall thickness is defined as the distance between the interostial line and external uterine profile at the midcoronal plane of the uterus; alternatively, if a coronal plane is not available, the mean anterior and posterior uterine wall thickness at the longitudinal plane could be used. Gynecological examination and two-dimensional ultrasound (2D US) are recommended for the evaluation of asymptomatic women. Three-dimensional (3D) US is recommended for the diagnosis of female genital anomalies in 'symptomatic' patients belonging to high risk groups for the presence of a female genital anomaly and in any asymptomatic woman suspected to have an anomaly from routine evaluation. Magnetic resonance imaging (MRI) and endoscopic evaluation are recommended for the subgroup of patients with suspected complex anomalies or in diagnostic dilemmas. Adolescents with symptoms suggestive for the presence of a female genital anomaly should be thoroughly evaluated with 2D US, 3D US, MRI and endoscopically. LIMITATIONS, REASONS FOR CAUTION The various diagnostic methods should always be used in the proper way and evaluated by experts to avoid mis-, over- and underdiagnosis. WIDER IMPLICATIONS OF THE FINDINGS The role of a combined US examination and outpatient hysteroscopy should be prospectively evaluated. It is a challenge for further research, based on diagnosis, to objectively evaluate the clinical consequences related to various degrees of uterine deformity. STUDY FUNDING/COMPETING INTERESTS None.

Abstract
OBJECTIVES To estimate, using a time and motion method, the time and labor costs associated with the administration of zoledronic acid and pamidronate in cancer patients with metastatic bone diseases. METHODS During clinic visits for participating patients receiving intravenous zoledronic acid or pamidronate, all times and activities associated with the administration of bisphosphonates were recorded by a trained observer using a stopwatch and data recording forms. The total time associated with the administration of bisphosphonates was estimated and converted to labor costs by applying corresponding health care professional hourly wage rates plus the fringe-benefit rate. The costs were presented in 2011 Canadian dollars. RESULTS A convenience sample of 37 patients from 2 hospital outpatient oncology clinics in Ontario and Quebec participated in the study. Nineteen patients were diagnosed with breast cancer and 18 with prostate cancer. The average patient age was 66 years, and patients had been diagnosed with cancer and metastatic bone disease for 8 years and 3 years, respectively. The times and costs associated with the administration of bisphosphonates for the 28 patients who did not receive concurrent chemotherapy during the scheduled clinic visits are also reported. The mean infusion time for patients receiving zoledronic acid was 20.6 minutes. With the use of ambulatory infusion devices, the mean infusion time of pamidronate was 23 minutes (limited to observations of patients who were seated during administration). In contrast, the mean infusion time using regular infusion devices was 162 minutes. The mean labor cost for administering zoledronic acid was $20. The mean labor cost for administering pamidronate was $10 using ambulatory infusion devices and $68 using regular infusion devices. CONCLUSION The time burden to cancer patients with metastatic bone disease who receive intravenous bisphosphonates and the costs to the health care system are substantial, especially when regular infusion devices are used.

Abstract
STUDY QUESTION What classification system is more suitable for the accurate, clear, simple and related to the clinical management categorization of female genital anomalies? SUMMARY ANSWER The new ESHRE/ESGE classification system of female genital anomalies is presented. WHAT IS KNOWN ALREADY Congenital malformations of the female genital tract are common miscellaneous deviations from normal anatomy with health and reproductive consequences. Until now, three systems have been proposed for their categorization but all of them are associated with serious limitations. STUDY DESIGN, SIZE AND DURATION The European Society of Human Reproduction and Embryology (ESHRE) and the European Society for Gynaecological Endoscopy (ESGE) have established a common Working Group, under the name CONUTA (CONgenital UTerine Anomalies), with the goal of developing a new updated classification system. A scientific committee (SC) has been appointed to run the project, looking also for consensus within the scientists working in the field. PARTICIPANTS/MATERIALS, SETTING, METHODS The new system is designed and developed based on (i) scientific research through critical review of current proposals and preparation of an initial proposal for discussion between the experts, (ii) consensus measurement among the experts through the use of the DELPHI procedure and (iii) consensus development by the SC, taking into account the results of the DELPHI procedure and the comments of the experts. Almost 90 participants took part in the process of development of the ESHRE/ESGE classification system, contributing with their structured answers and comments. MAIN RESULTS AND THE ROLE OF CHANCE The ESHRE/ESGE classification system is based on anatomy. Anomalies are classified into the following main classes, expressing uterine anatomical deviations deriving from the same embryological origin: U0, normal uterus; U1, dysmorphic uterus; U2, septate uterus; U3, bicorporeal uterus; U4, hemi-uterus; U5, aplastic uterus; U6, for still unclassified cases. Main classes have been divided into sub-classes expressing anatomical varieties with clinical significance. Cervical and vaginal anomalies are classified independently into sub-classes having clinical significance. LIMITATIONS, REASONS FOR CAUTION The ESHRE/ESGE classification of female genital anomalies seems to fulfill the expectations and the needs of the experts in the field, but its clinical value needs to be proved in everyday practice. WIDER IMPLICATIONS OF THE FINDINGS The ESHRE/ESGE classification system of female genital anomalies could be used as a starting point for the development of guidelines for their diagnosis and treatment.

Anomalies are classified into the following main classes, expressing uterine anatomical deviations deriving from the same embryological origin: U0, normal uterus; U1, dysmorphic uterus; U2, septate uterus; U3, bicorporeal uterus; U4, hemi-uterus; U5, aplastic uterus; U6, for still unclassified cases. Main classes have been divided into sub-classes expressing anatomical varieties with clinical significance. Cervical and vaginal anomalies are classified independently into sub-classes having clinical significance. The ESHRE/ESGE classification of female genital anomalies seems to fulfil the expectations and the needs of the experts in the field, but its clinical value needs to be proved in everyday practice. The ESHRE/ESGE classification system of female genital anomalies could be used as a starting point for the development of guidelines for their diagnosis and treatment.

Abstract
BACKGROUND Studies have demonstrated that patients at low risk for febrile neutropenia (FN) complications can be treated safely and effectively at home. Information on patient preferences for outpatient treatment of this condition will help to optimize health care delivery to these patients. The purpose of this study was to elicit non-Hodgkin lymphoma patients' preferences on attributes related to outpatient treatment of FN. METHODS We used a self-administered discrete choice experiment questionnaire based on the attributes of out-of-pocket costs, unpaid caregiver time required daily, and probability of return to the hospital. Ten paired scenarios in which levels of the attributes were varied were presented to study patients. For each pair, patients indicated the scenario they preferred. Adjusted odds ratios (ORs) of accepting a scenario that described outpatient care for FN were estimated. RESULTS Eighty-eight patients completed the questionnaire. Adjusted ORs [95 % confidence intervals] of accepting outpatient care for FN were 0.84 [0.75, 0.95] for each $10 increase in out-of-pocket cost; 0.82 [0.68, 0.99] for each 1 h increase in daily unpaid caregiver time; and 0.53 [0.50, 0.57] for each 5 % increase in probability of return to the hospital. CONCLUSIONS Probability of return to the hospital was the most important attribute to patients when considering home-based care for FN. Patients considered out-of-pocket costs and unpaid caregiver time to be less important than probability of return to the hospital. This study identifies factors that could be incorporated into outpatient delivery systems for FN care to ensure adequate patient uptake and satisfaction with such programs.

Abstract
58 Background: Zoledronic acid (ZOL) therapy is associated with severe (i.e., grade 3/4 according to CTCAEv4.0) hypocalcemia and hypophosphatemia in a subset of patients with metastatic castration-resistant prostate cancer (mCRPC) to bone. However, as opposed to the distinct clinical picture of hypocalcemia, the symptoms of hypophosphatemia are less pathognomonic. Furthermore, the rate of hypophosphatemia is not regularly reported. Methods: To characterize the rate and circumstances of severe hypophosphatemia in mCRPC patients undergoing ZOL therapy, we identified mCRPC patients receiving at least 3 doses of ZOL therapy at our Centre between 2004 and 03/2011. Patient demographics, disease and laboratory parameters were extracted by using the Oncology Symptom Control and Information Resource database, and by means of manual chart review. Results: 11 of 112 patients (10%) developed grade 3/4 hypophosphatemia (nadir) after 241±223 days (mean±SD) following the first dose of ZOL. Only one patient presented with concomitant severe hypocalcemia. Interestingly, the hypophosphatemia nadir coincided with rising PSA readings in 9 out of 10 informative patients. Furthermore, ZOL-associated severe hypophosphatemia identified mCRPC patients with worse outcome (time from CRPC diagnosis to death 628±317 days, versus 901±526 days in CRPC patients without severe ZOL-associated hypophosphatemia, p < 0.028). Conclusions: 10% of mCRPC patients undergoing ZOL therapy presented with grade 3/4 hypophosphatemia. While hypocalcemia usually occurs within the first 6 months of ZOL therapy, ZOL-associated severe hypophosphatemia is a relatively late event. It appears to occur at the time of disease progression and is associated with a poor outcome.

Abstract
Constipation is a highly prevalent and distressing symptom in patients with advanced, progressive illnesses. Although opioids are one of the most common causes of constipation in patients with advanced, progressive illness, it is important to note that there are many other potential etiologies and combinations of causes that should be taken into consideration when making treatment decisions. Management approaches involve a combination of good assessment techniques, preventive regimens, appropriate pharmacological treatment of established constipation, and frequent monitoring. In this vulnerable patient population, maintenance of comfort and respect for individual preferences and sensitivities should be overriding considerations when making clinical decisions. This consensus document was developed by a multidisciplinary group of leading Canadian palliative care specialists in an effort to define best practices in palliative constipation management that will be relevant and useful to health care professionals. Although a wide range of options exists to help treat constipation and prevent its development or recurrence, there is a limited body of evidence evaluating pharmacological interventions. These recommendations are, therefore, based on the best of the available evidence, combined with expert opinion derived from experience in clinical practice. This underscores the need for further clinical evaluation of the available agents to create a robust, evidence-based foundation for treatment decisions in the management of constipation in patients with advanced, progressive illness.

Abstract
OBJECTIVE To provide family physicians and pharmacists with practical, evidence- and expertise-based guidance on choosing the safest approach to using analgesics to manage patients with musculoskeletal pain. SOURCES OF INFORMATION Health care providers from family practice, rheumatology, gastroenterology, hepatology, internal medicine, and pharmacy participated in an educational needs assessment regarding the management of pain and the safety of commonly used analgesics. Feedback from one-on-one interviews was compiled and distributed to participants who selected key topics. Topics chosen formed the basis for the discussions of this multidisciplinary panel that reviewed data on the safety of analgesics, particularly in regard to comorbidity and concurrent use with other therapies. MAIN MESSAGE Treatment should begin with an effective analgesic with the best safety profile at the lowest dose and escalate to higher doses and different analgesics as required. Acetaminophen is a safe medication that should be considered first-line therapy. Nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with potential adverse gastrointestinal, renal, hepatic, and cardiovascular effects. Physicians should not prescribe NSAIDs before taking a careful history and doing a physical examination so they have the information they need to weigh the risks (adverse effects and potential drug interactions) and benefits for individual patients. CONCLUSION Taking a complete and accurate history and doing a physical examination are essential for choosing the safest analgesic for a particular patient.

The splanchnic mesodermal plate directs spleen and pancreatic laterality, and is regulated by Bapx1/Nkx3.2. Development 2004; 131:4665-75.

Abstract
The mechanism by which left-right (LR) information is interpreted by organ primordia during asymmetric morphogenesis is largely unknown. We show that spleen and pancreatic laterality is dependent on a specialised, columnar mesodermal-derived cell layer referred to here as the splanchnic mesodermal plate (SMP). At early embryonic stages, the SMP is bilateral, surrounding the midline-located stomach and dorsal pancreatic bud. Under control of the LR asymmetry pathway, the left SMP is maintained and grows laterally. Mice carrying the dominant hemimelia (Dh) mutation lack the SMP. Significantly, the mice are asplenic and the pancreas remains positioned along the embryonic midline. In the absence of Fgf10 expression, the spleno-pancreatic mesenchyme and surrounding SMP grow laterally but contain no endodermal component, showing that leftward growth is autonomous and independent of endoderm. In the Bapx1(-/-) mutants, the SMP is defective. Normally, the SMP is a source for both Fgf9 and Fgf10; however, in the Bapx1 mutant, Fgf10 expression is downregulated and the dorsal pancreas remains at the midline. We conclude that the SMP is an organiser responsible for the leftward growth of the spleno-pancreatic region and that Bapx1 regulates SMP functions required for pancreatic laterality.

Do physicians follow systemic treatment and funding policy guidelines? JOURNAL OF POPULATION THERAPEUTICS AND CLINICAL PHARMACOLOGY 2004; 11:e168-78.

Abstract
BACKGROUND The use of bisphosphonates for the prevention of skeletal related events in women with bone metastases from breast cancer is well established. We undertook an evaluation of bisphosphonate use in clinical practice in three Canadian cancer centres. In addition we assessed whether or not physicians at these centres are following their local treatment guidelines and funding policies. METHODS Charts and electronic files of patients who had received either clodronate or pamidronate at any time between January 2000 and December 2001 at three Canadian cancer centres were retrospectively reviewed. RESULTS There has been a marked improvement in the time between the diagnosis of bone metastases and the commencement of bisphosphonates from a median of 155 days in 1998 to 24 days in 2001. However, despite a local funding policy requiring that oral clodronate be the first bisphosphonate used, this was the case in only 67% of patients. In addition, despite one centre's guidelines recommending that bisphosphonates be stopped once the patient was progressing, 90% of their patients remained on bisphosphonates until they died. CONCLUSIONS A considerable amount of effort is spent on the creation of "evidence based" treatment guidelines. Funding agencies develop policies based on these treatment guidelines, but often funding is more restrictive than the treatment guideline would suggest. It is clear from this review that physicians still appear to manage a substantial proportion of patients outside of funding policies, but within evidence based recommendations. Therefore, a need exists for either the creation of guidelines and policies that physicians will follow or the implementation of methods to ensure that restrictive policies are actually followed.

Abstract
BACKGROUND Diagnostic hysteroscopy has not yet been generally accepted as a well-tolerated office procedure. The aim of our study was to verify compliance, side-effects and haemodynamic variations when a mini-hysteroscope is used. METHODS A prospective randomized trial on office hysteroscopy was performed by comparing the use of a traditional 5 mm hysteroscope (group A) and of a 3.3 mm mini-hysteroscope (group B). Two patient groups (A and B), each comprising 100 cases, were formed on the basis of a randomized computer-generated list. RESULTS A marked reduction in the mean (+/- SD) pelvic pain score during office hysteroscopy was seen in group B (2.3 +/- 2.1) as compared with group A (4.6 +/- 2.2) (P < 0.0001, Mann-Whitney test). This result was also confirmed when using an alternative approach: four classes of pelvic pain at the visual analogue score (VAS). A significant reduction was observed in the incidence of moderate and severe pelvic pain in group B at the end of the examination (P = 0.001) and 5-10 min later (P < 0.05). CONCLUSIONS The use of mini-hysteroscopes (3.3 mm with diagnostic sheath) lowers considerably the level of pelvic pain the patients feel: it is halved in comparison with traditional calibre hysteroscopes (2.3 +/- 2.1, on a 0-10 VAS). Furthermore the outpatient hysteroscopy failure rate is less than half (2%) with the mini-hysteroscope compared with the traditional 5 mm hysteroscope (5%). As for side-effects and haemodynamic parameters, no differences were observed except for an increase (P < 0.05) in bradycardia in group B. The advantage of this technique is self-evident, if the patients' compliance is taken into account: in many cases the introduction or withdrawal of the vaginal speculum was reported as the greatest discomfort.

Abstract
OBJECTIVE To report hemolytic crisis in a woman with glucose-6-phosphate dehydrogenase (G6PD) deficiency who underwent diagnostic hysteroscopy using endoscopic instruments sterilized in gluteraldehyde and phenol disinfectant. DESIGN Case report. SETTING Surgical unit of a university hospital. PATIENT(S) A 53 year-old woman with endometrial thickening on ultrasonography. INTERVENTION(S) Diagnostic hysteroscopy. MAIN OUTCOME MEASURES Laboratory tests. RESULT(S) The patient experienced abdominal pain and acute hypotension 10 minutes after diagnostic hysteroscopy. We attributed this event to the exposure of her genital mucosa caused by the hysteroscopic chemical disinfectant. CONCLUSION(S) Chemical sterilization of endoscopes can cause clinical manifestations in people with G6PD deficiency, a common enzyme abnormality. The phenol content in some chemical disinfectants for endoscopic instruments can also cause hemolytic crisis.

Abstract
OBJECTIVE To evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) as a pain control method during office hysteroscopy. DESIGN A prospective, randomized study. SETTING Centre for Minimally Invasive Surgery, Department of Gynecological Science and Perinatology, "La Sapienza" University, Rome, Italy. PATIENT(S) One hundred forty-two patients undergoing office hysteroscopy. INTERVENTION(S) Application of a TENS device on the patient's abdomen before and during office hysteroscopy. MAIN OUTCOME MEASURES The level of pain experienced by the patients was assessed using a 10 cm visual analog scale; the side effects and changes in the hemodynamic parameters were evaluated. RESULT(S) The patients treated with TENS during hysteroscopy (group A, n = 71) were compared with a control group (group B, n = 71) on whom the TENS device was not used. The women in the TENS group experienced a significantly lower level of pain during hysteroscopy. No differences in side effects were observed between both group. CONCLUSION(S) TENS is a simple, efficient, and safe method of relieve pain during office hysteroscopy.
