The intrauterine contraceptive device (IUD) is effective and reversible and has a high continuation rate. It can also be used within 7 days postcoitus. Developed separately by Richter, Grafenberg, and Ota between 1909 and 1934, the IUD gained popularity in the 1960s and 1970s with the introduction of the Margulies Spiral, the Lippes Loop, the Birnberg Bow, and the Dalkon Shield. The last proved dangerous, and the IUD became unpopular. The 4 IUDs which are available in Canada include the TCu-380S (GYNE T Slimline), the TCu-200, the NOVA-T, and the Progestasert. All are T shaped and medicated (copper or progesterone). The 1st and 3rd can be left in situ for 10 years; the 2nd, for 4 years; and the 4th, for 1 year. The NOVA-T has a copper wire with a silver core and is inserted with a unique pull-push technique. The Progestasert, which contains 38 mg of progesterone, releases 65 mcg of the hormone daily. The best candidate for IUD use is parous, but not pregnant, is in a stable monogamous relationship, and has a healthy reproductive tract and no history of ectopic pregnancy, sexually transmitted disease, pelvic inflammatory disease, undiagnosed genital bleeding, endometrial or cervical neoplasia, abnormal endometrial anatomy, compromised immune system, allergy to copper, or Wilson's Disease. The only infection related to the IUD is that associated with insertion. Such an infection is polymicrobial and involves the endogenous, cervicovaginal flora (primarily anaerobes). It is usually asymptomatic and contained by the immune system. 200 mg of Doxycycline can be given orally as a prophylactic 1 hour prior to insertion. A nonprescription, nonsteroidal, anti-inflammatory drug, also taken 1 hour before the procedure, will prevent pain and a vasovagal reaction. Paracervical anesthesia should be used. If the depth of the uterus is less than 6 cm or greater than 10 cm, another form of contraception should be used. Although little research is being done in Canada on new IUDs

Full Text Available The intrauterine device (IUD is a widely used, highly effective method of birth control. Uterine perforation is a rare yet serious complication and is usually seen during insertion of the IUD. A regular examination is necessary for follow-up. We present a patient with an IUD that had perforated the cervix. The diagnosis was made during routine gynecological examination, and the patient was treated in a timely manner before any complications such as ectopic pregnancy, intrauterine pregnancy, infection or irreversible harm to the cervix arose. This case stresses the importance of regular visits to maintain health and diagnose possible adverse effects of intrauterine contraceptive methods.
Background: Intrauterine contraceptive device (IUCD) is one of the reversible methods of contraception. Its use has increased steadily worldwide. However, some women reject it based on presumed complications associated with its use. Aim: To determine the complications reported by women, action taken on the ...
Full Text Available Background. Intrauterine devices (IUD are commonly used birth control methods. Colonic perforation is an infrequent but serious complication of IUD. Case. A 34-year-old woman with 2-years history of IUD, inserted at early puerperal period, presented to gynecologist with chronic pelvic pain and dyspareunia. Radiological assessment revealed that there were two copper-T devices: one in uterine cavity and another in the colonic lumen. Attempts of retrieval with colonoscopy and laparoscopy were unsuccessful. Intrauterine device embedded in sigmoid colon wall was removed with resection of the involved segment and primary anastomosis was performed. Conclusion. Although there are cases in literature that are successfully managed with colonoscopy, in chronic cases, formation of granulation tissue complicates retrieval of an IUD by this intervention.
Full Text Available Background. Uterine perforation and transvesical migration of an intrauterine device are rare complications. Case. A 28-year-old woman who had an intrauterine device was admitted to our outpatient clinic with complaints of amenorrhea lasting 5 weeks and pelvic pain lasting a year. Transvaginal ultrasonography revealed embedding of the intrauterine device in the bladder. The misplaced device was removed by laparotomy. Conclusion. The followup of intrauterine device localization with transvaginal ultrasonography is essential for early detection of possible serious complications.

The worldwide popularity and usage of intrauterine devices (IUDs) plummeted in the 1970s, when grim reports of septic abortions and pelvic inflammatory disease were published. Although the Dalkon Shield ultimately was determined to be the culprit for these problems, the reputation of all IUDs was damaged, and their popularity spiraled downward. The stigma continues, despite the proven safety and efficacy of newer IUDs, particularly the ParaGard T 380A and the Progestasert, which are now the only two IUDs approved for use in the United States. This article will review how the IUD works and will focus on dispelling the misconceptions surrounding its use. Rigid patient-selection guidelines and strict aseptic insertion techniques can provide safe, long-term, cost-effective, and highly efficacious contraception for monogamous women. Practitioners who follow these guidelines should not fear prescribing IUDs as a contraceptive device in the appropriate female population.
This study aimed to evaluate the feasibility of conducting a randomized controlled trial of postpartum intrauterine device insertion and to demonstrate that the postpartum intrauterine device is acceptable to women. Women attending prenatal care at a maternity hospital in Lilongwe, Malawi were recruited into a trial ...

Globally, 14% of women use intrauterine contraceptive devices (IUCDs) for prevention of unplanned pregnancy. In Australia, the use of IUCDs is negligible at METHODS: GPs participated in qualitative interviews in February-May 2016, exploring their knowledge, attitudes and practice around IUCDs. Data were thematically analysed. Overall, 17 GPs were interviewed. They identified key barriers to prescription of IUCDs as misconceptions brought to the consultation, lack of current GP inserters, and issues in referral of patients for insertion. Barriers to prescribing IUCDs create challenges for women in accessing all available contraceptive options. Potential solutions to increase IUCD uptake might include local directories of GP inserters and targeted promotion of IUCD use. Increased GP training is necessary to expand the number of current GP inserters.
Full Text Available Objective: To investigate a level of knowledge about intrauterine device between females who were examined in our gynecology department. Metods: The study was conducted at Gynecology and Obstetric Department of Bakirkoy Dr. Sadi Konuk Teaching and Research Hospital between August 2012-November 2012. The study were included 189 patients who accepted to participate. For collecting data; a form of questionnaire was used which has gived information about the intrauterine device (IUD and status of socio-demographic characteristics of the patients. The questionnaire were administered by the researchers in a separate room as a face-to-face interviews. SPSS 20.0 (SPSS Inc, Chicago, IL, USA program was used for statistical analysis. Results: The mean age of the women in the study was 31.1 ± 9.9. 44.7% of women were not using any modern contraceptive method. IUD utilization rate was 3.2%. 1.6% of women had never heard IUD, %76.1 women heard copper IUD. 42% of respondents gave the wrong answer to IUD inserted into ovaries. Conclusion: The IUD which is a cheap, does not require patient compliance, and has high efficacy. In this study, we were not found a statisfically significant difference for answers to questions in patients with different socio-demographic characteristics. The main result of the study was; among all parcipitians ,even health care workers there was an important disability about level of knowledge for IUD. It is great importance the whole society, including health professionals must train about family planning. [Cukurova Med J 2013; 38(3.000: 440-445

Studies conflict on whether the duration of use of the copper intrauterine device is longer than that of the levonorgestrel intrauterine device, and whether women who continue using intrauterine devices differ from those who discontinue. We sought to assess continuation rates and performance of levonorgestrel intrauterine devices compared with copper intrauterine devices over a 5-year period. We performed a retrospective cohort study of 1164 individuals who underwent intrauterine device placement at an urban academic medical center. The analysis focused on a comparison of continuation rates between those using levonorgestrel intrauterine device and copper intrauterine device, factors associated with discontinuation, and intrauterine device performance. We assessed the differences in continuation at discrete time points, pregnancy, and expulsion rates using χ 2 tests and calculated hazard ratios using a multivariable Cox model. Of 1164 women who underwent contraceptive intrauterine device insertion, 956 had follow-up data available. At 2 years, 64.9% of levonorgestrel intrauterine device users continued their device, compared with 57.7% of copper intrauterine device users (P = .11). At 4 years, continuation rates were 45.1% for levonorgestrel intrauterine device and 32.6% for copper intrauterine device (P 4 years was 0.71 (95% confidence interval, 0.55-0.93) and >5 years was 0.82 (95% confidence interval, 0.64-1.05) after adjusting for race, age, parity, and education. Copper intrauterine device users were more likely to experience expulsion (10.2% copper intrauterine device vs 4.9% levonorgestrel intrauterine device, P < .01) over the study period and to become pregnant in the first year of use (1.6% copper intrauterine device vs 0.1% levonorgestrel intrauterine device, P < .01). We found a difference in continuation rates between levonorgestrel and copper intrauterine device users at 4 years but not at 5 years. Copper intrauterine device users were more likely

Intra-uterine device (IUD) is one of the birth control methods, which is available for nulliparous women, even though misconceptions still remain in medical or popular opinion. Only 1.3 % of nulliparous have a IUD as contraception in France while it is the second methods used by all women, after pill. The best contraception is the one chosen by women; however, the choice for a nulliparous of an IUD may be really difficult, despite the increasing number of women wishing to use it. Long-acting reversible contraceptives utilization, including IUD, is probably one of the issues to decrease the unintended pregnancies. An exhaustive and clear information about IUD is necessary to allow an informed and real choice. This prescription must consider contraindications and medical conditions for safe insertion, especially to avoid infection by screening STD (Chlamydia trachomatis and Nesseria gonorrhoeae) in nulliparous women<25 years old. Insertion must be effected with usual precautions and short or SL IUD preferred. Even if side effects such as expulsion, pelvic pains or dysmenorrhea are more frequent by nulliparous, IUD is a first intention choice for contraception to be consider, that women could obtain easily, including in emergency contraception situation.

Insertion of an intrauterine device (IUD) immediately after an abortion has several potential advantages. The woman is known not to be pregnant, a major concern for clinicians. For example, many clinicians refuse to insert an IUD in a woman who is not menstruating. After induced abortion, a woman's motivation to use contraception may be high. However, insertion of an IUD immediately after a pregnancy ends carries potential risks as well. For example, the risk of spontaneous expulsion may be increased due to recent cervical dilation. To assess the safety and efficacy of IUD insertion immediately after spontaneous or induced abortion. We used MEDLINE, Popline, and EMBASE computer searches, supplemented by review articles and contacts with investigators. We sought all randomized controlled trials that had at least one treatment arm that involved IUD insertion immediately after an induced abortion or after curettage for spontaneous abortion. We identified 12 trials which described random assignment but excluded three from this review. Two of these revealed unethical research conduct, and one used alternate assignment to treatments. We evaluated the methodological quality of each report and abstracted information onto a data collection form. We focused on gross discontinuation rates (single-decrement life table analysis) for accidental pregnancy, perforation, expulsion, and pelvic inflammatory disease. We entered the data into RevMan 3.1 for analysis of Peto odds ratios. In large multicenter trials, the TCu 220C device proved superior to either the Lippes Loop D or the Copper 7 IUDs for immediate postabortal insertion. In single-center trials, the Nova T IUD had a significantly higher discontinuation rate for pregnancy than did the Multiload 250 (OR 4.5; 95% CI 1.0-19.8), while the Nova T had a significantly lower discontinuation rate for pregnancy than did the TCu 200 (OR 0.3; 95% CI 0.1-0.9).

An intrauterine device placed immediately following a delivery can serve as an effective and safe contraceptive strategy in the postpartum period. There is limited evidence that the levonorgestrel intrauterine system may have a higher rate of expulsion compared to the copper intrauterine device; however, rates of expulsion for these 2 intrauterine device types have not been compared directly. We sought to compare expulsion rates by 12 weeks' postpartum for the levonorgestrel intrauterine system and copper intrauterine device. We enrolled women who received postplacental intrauterine devices at 2 urban hospitals. Eligible women were ≥18 years old, English- or Spanish-speaking, with singleton vaginal delivery at ≥35 weeks' gestation. Intrauterine devices were inserted within 10 minutes of placental delivery by trained providers using ring forceps or the operator's hand. Intrauterine device location was evaluated via abdominal ultrasound at 24-48 hours' postpartum, and via transvaginal ultrasound 6 and 12 weeks later, categorizing position of the intrauterine device at the fundus, below the fundus but above the internal os, any part of the intrauterine device below the internal os (partial expulsion), or no intrauterine device visualized. Outcomes included intrauterine device expulsion and method continuation. We used multivariable logistic regression to identify factors associated with expulsion. We enrolled 123 women ages 18-40 years. Of these, 68 (55%) initiated levonorgestrel intrauterine system and 55 (45%) initiated copper intrauterine device. Groups were similar except more copper intrauterine device users were Hispanic (66% vs 38%) and fewer were primiparous (16% vs 31%). Among the 96 (78%) with 12-week follow-up, expulsion was higher for levonorgestrel intrauterine system users (21/55 or 38%) than for copper intrauterine device users (8/41 or 20%) (odds ratio, 2.55; 95% confidence interval, 0.99-6.55; P = .05). At 24 hours' postpartum, there was no

An opinion paper of 2012 by the American College of Obstetricians and Gynecologists recommends Mirena and Paragard for use in nulliparous and adolescent women. However, these IUDs are not designed for young women and are not optimal as they often lead to early discontinuation. Objective: This article was written with the objective to respond to the urgent need to improve intrauterine contraception as it is likely that the objectives of LARC will not be met without significant improvement of IUD design. Anatomical variations in size and shape of the uterus are not sufficiently considered, producing harm and suffering, which often lead to early removal of the IUD. Proposed problem solving: The article describes why IUDs should be revisited to meet the challenge of LARC and proposes how to solve these problems. The opinion statement presented here may be considered provocative but is based on hundreds of women with IUD problems who consult or are referred to the practices of the authors of this article due to the disproportion between the IUD and their small uterine cavity. The solution is simple but requires a revision of the current design of IUDs. One-dimensional (longitudinal IUDs are likely to be the first option.

To compare the effectiveness of medicated γ intrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. At the 12(th) month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90(th) day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P0.05). The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.

Infections in the female pelvis can present clinically in various ways and the causing agent can be difficult to trace. In this paper we present updated knowledge about infections caused by the bacterium Actinomycosis in relation to intrauterine device use. The article is based on own clinical experience and literature identified through a non-systematic search in PubMed. Actinomycosis in the female pelvis is a rare disease and the pathogenesis is still obscure. The incidence in Scandinavia has not been established. The infection can cause tumor-like structures resulting in bowel and urinary obstruction. The bacteria can be difficult to detect. Preferably the agent should be demonstrated in a specimen from the infected area to ensure the correct diagnosis. However, Actinomyces is a normal inhabitant of the gastrointestinal tract and is also present in 5 % of cervical smears from healthy women. The optimal treatment of actinomycosis is long-term treatment with penicillin, alone or in addition to surgery. To avoid unnecessary and potentially difficult surgical procedures, actinomycosis should be a differential diagnosis when women with a longstanding intrauterine device develop signs of infection in addition to a pelvic mass. Intrauterine devices should be replaced every fifth year and should be removed at menopause.

In-hospital placement of intrauterine devices and contraceptive implants following vaginal and cesarean delivery is increasingly popular and responds to maternal motivation for highly effective postpartum contraception. Immediate postpartum intrauterine device insertion is associated with higher expulsion than interval placement, but emerging evidence suggests that the levonorgestrel intrauterine device may have a higher expulsion rate than the copper intrauterine device. This study evaluated in-hospital provision, expulsion, and 6-month continuation of immediate postpartum copper T380 intrauterine devices, levonorgestrel intrauterine devices, and contraceptive implants. We offered enrollment in this prospective observational trial to women presenting to the University of Utah labor and delivery unit from October 2013 through February 2016 who requested an intrauterine device or implant for postpartum contraception during prenatal care or hospitalization at the time of delivery. Following informed consent, participants completed questionnaires prior to hospital discharge and at 3 and 6 months postpartum. Data on expulsions at 6 months were validated by chart abstraction. During the study period, 639 patients requested a postpartum intrauterine device or implant and 350 patients enrolled in prospective follow-up prior to discharge from the hospital. Among enrollees, 325 (93%) received their preferred contraceptive device prior to hospital discharge: 88 (27%) copper intrauterine device users, 123 (38%) levonorgestrel intrauterine device users, and 114 (35%) implant users. Participants predominantly were Hispanic (90%), were multiparous (87%), reported a household income postpartum, 289 of 325 device recipients (89%) completed follow-up. Among levonorgestrel intrauterine device users 17% reported expulsions relative to 4% of copper intrauterine device users. The adjusted hazard ratio for expulsion was 5.8 (confidence interval, 1.3-26.4). There was no statistically

A woman who had a copper 7 coil inserted without difficulty, in 1978 decided to have another baby, and in February 1980, she asked for the device to be removed. Her (GP) general practitioner could not find the threads so she was referred to me. She did mention to her GP that she had noticed the threads appearing at her anus after defecation. The GP did a rectal examination and reassured her, suggesting that she had a vivid imagination. I saw her later that month and found no abnormality apart from a retroverted uterus and could not feel the coil with the uterine sound or hook within the uterine cavity. An X-ray of the abdomen showed that the IUD was identifiable in the midline front of the sacrum, and would appear to be in the uterus. In May 1980, she was admitted to hospital for removal of the coil. She told my senior house officer that she had felt the strings rectally: this observation was dismissed and not recorded in the notes. At operation I found a normal pelvis with retroverted uterus but no coil. Laparoscopy revealed no adhesions and no evidence of pelvic infection, but something seemed to be distorting the cavity of the sigmoid colon. It was then that my senior house officer mentioned that it was this patient who had thought she had felt the strings coming out of the rectum. She was asked to return as an outpatient 2 weeks later for sigmoidoscopy, after full bowel preparation. On sigmoidoscopy, the coil threads were readily visible and the copper 7 was found embedded 1/2 under the mucosa of the sigmoid colon at 17 cm. I grasped the free end with biopsy forceps and withdrew the coil, considerable force being needed. I prescribed ampicillin and metronidazole for 4 days and warned her about possible complications. However, the procedure caused no discomfort and there were no complications. Assuming the coil had been inserted into the uterine cavity, it it suprising that it had perforated the uterus and the sigmoid colon without causing pelvic sepsis and
Full Text Available An 86-year-old woman with diabetes mellitus and severe decubitus at the sacral and calcaneal regions stemming from poor daily activity was diagnosed with pyometra perforation caused by Actinomyces. No foreign materials, including an IUD, were found inside the uterus. Pyometra is usually caused by Enterobacteriaceae or anaerobes derived from the gastrointestinal tract. The virulence of Actinomyces is rather low, and, in almost all the reported cases of Actinomyces-related pyometra, an intrauterine device (IUD was involved. Although rare, Actinomyces may be ascribed as a virulent pathogen that causes pyometra in the absence of foreign materials.

This increased utilization may have substantially contributed to the decline in the percentage of unintended pregnancies in the US. Evidence-based practices have increased the number of women who are medically eligible for IUDs and have enabled more rapid access to the methods. Many women enjoy freedom to use IUDs without cost, but for many the impact of the Affordable Care Act has yet to be realized. Currently, there are three hormonal IUDs and one copper IUD available in the US. Each IUD is extremely effective, convenient, and safe. The newer IUDs have been tested in populations not usually included in clinical trials and provide reassuring answers to older concerns about IUD use in these women, including information about expulsion, infection, and discontinuation. On the other hand, larger surveillance studies have provided new estimates about the risks of complications such as perforation, especially in postpartum and breastfeeding women. This article summarizes significant features of each IUD and provides a summary of the differences to aid clinicians in the US and other countries in advising women about IUD choices.

After this time, the asymptomatic patient had a gynecological appointment, during which a doctor did not find the strings of IUD in the speculum. Ultrasound examination did not reveal the presence of the IUD in the uterine cavity, which led to the suspicion of its presence outside the uterus. The patient was referred to a hospital, where she underwent ultrasound and X-ray examination of the pelvis that confirmed the presence of the IUD outside the uterus. Laparoscopy was performed during which the IUD was localized as being embedded in the omentum. It was removed by performing a resection of a part of the omentum with inflammatory infiltration. The patient was discharged home on the second postoperative day in a good condition. This case confirms the need for gynecological control and ultrasound examination shortly after insertion. An ultrasound or/and X-ray is mandatory in any case of absence of IUD strings previously visible in the vagina, if the patient did not observe its expulsion.

There has been little research published on the impact of intrauterine contraceptive (IUC) methods on sexual functioning. This study aimed: (i) to assess different aspects of sexual functioning, including the prevalence of sexual dysfunction in women using a levonorgestrel intrauterine system (LNG-IUS); (ii) to compare this prevalence with that among copper-releasing intrauterine device (Cu-IUD) users; and (iii) to identify the relationship between psychological variables and sexual functioning in women using one of the aforementioned IUCs. In a multicenter cross-sectional study, 845 women with an IUC were invited to fill out a questionnaire. The latter was returned by 402 (48%) of them: 353 women were LNG-IUS users (88%) and 49 were Cu-IUD users (12%). The questions asked pertained to depression, well-being, marital relation quality, and sexual functioning. Sexual functioning was measured with the short sexual functioning scale. One-third of LNG-IUS users (33%) reported a sexual dysfunction. Of those, 20% reported an increased sexual desire, 25% a decreased sexual desire, 5% arousal problems, and 8% orgasm problems. Women using a LNG-IUS did not differ significantly in distribution, type, or prevalence (32.9% vs. 36.7%) of sexual dysfunction, nor in depressive symptoms (Beck Depression Inventory score; 4.7 vs. 3.9; P = 0.33), general well-being (WHO-5 well-being scale score; 16.8 vs. 17.7; P = 0.170), or partner relationship quality (Dyadic Adjustment Scale score; 107 vs. 108; P = 0.74) compared to Cu-IUD users. Overall, the perceived influence of IUCs on sexual functioning was in the lower range and did not differentiate LNG-IUS greatly from Cu-IUD-users. Women using a LNG-IUS do not differ from those wearing a Cu-IUD with regard to psychological and sexual functioning. The perceived impact of IUD use on sexuality should not be overestimated. © 2011 International Society for Sexual Medicine.

The intrauterine device (IUD) and intrauterine system (IUS) are widely used forms of long-acting reversible contraception. Occasionally, IUD/IUS users have an ultrasound scan that shows a low-lying IUD/IUS or an IUD/IUS is found incidentally on scan to be low-lying within the uterus. No formal guidelines exist on the clinical implications of this scenario or the most appropriate management. We report here on a systematic review of the literature. A search of the online database PubMed was performed to identify articles relating to low-lying or malpositioned IUD/IUS. A total of 1101 articles was identified, and 15 were determined to be relevant to the research question. There is little published evidence to determine the nature and extent of the clinical relevance of a low-lying IUD. We recommend individualised management of these women, with particular caution in younger women and those with a history of previous IUD/IUS expulsion. Consideration may be given to attempting to readjust the IUD/IUS position, but if removal is performed, immediate replacement is essential if provision of alternative effective contraception has not been established.

Use of modern contraceptive methods has been shown to reduce unwanted pregnancy, high parity and maternal mortality. Intrauterine contraceptive devices which are among the safest and most effective reversible contraceptives available, are particularly suitable for women in developing countries as they are affordable, convenient to use, do not require re -supply visits and are very cost-effective. The aim of this study is to determine the socio-demographic characteristics of intrauterine contraceptive device acceptors, the pattern of insertions and complications at the University of Uyo Teaching hospital, Uyo. The record cards of all clients who had intrauterine contraceptive device inserted at the family planning clinic over a six-year period were reviewed. During the study period, there were 852 new contraceptive acceptors out of which 39.7% accepted the intrauterine contraceptive device. The modal age group of the clients was 25-29 years (32.5%). Acceptance of intrauterine contraceptive device was most common among multiparous clients (65.1%). Majority of the acceptors were married (90.0%), Christians (98.8%) and 72.8% had at least secondary school education. Clinic personnel (65.7%) and friends/relatives (21.3%) were the most common sources of information on contraception. Most (93.5%) of the clients had their intrauterine contraceptive devices inserted within 7 days of menstruation. Lower abdominal pain (5.5%) and vulval/vaginal itching (5.3%) were the most common complications. The acceptors of intrauterine contraceptive devices in our center were young, multiparous and educated women. Increasing mass media involvement in the dissemination of accurate information about intrauterine contraceptive devices to the general populace, the introduction of postpartum and post-abortal intrauterine contraceptive device insertions and the encouragement of our grandmultiparous women to accept intrauterine contraceptive device would lead to an increase in its acceptance and

Widespread and increased availability of oral emergency contraception (EC) over the past 10 years has made little difference to rates of unintended pregnancy, abortion and repeat abortion amongst teenagers. The insertion of an intrauterine device for EC (EC-IUD) is 98-99% effective compared with 85% for oral methods and can be used for ongoing, long-term reversible contraception. However this method is seldom used for teenagers, a group with a high risk of unintended pregnancy, and there is little published data on the use of EC-IUD in this group. An anonymous case note review of EC-IUD use in teenagers in three centres in the UK was conducted to quantify provision, to identify insertion difficulties and short-term complications and to ascertain compliance with national guidance concerning sexually transmitted infection (STI) risk assessment and prophylaxis. A total of 103 cases was identified over 4 years (2007-2010) from the three centres (London, Liverpool and Aberdeen). The results show that the majority of fittings were straightforward (94%) with few complications. Antibiotic prophylaxis was deemed necessary in 64% of attenders. The authors recommend that with STI screening and appropriate antibiotic prophylaxis, use of IUDs in women under the age of 20 years should be unrestricted both for long-term contraception and for EC.

The aims of the study were to evaluate whether three-dimensional transvaginal ultrasound (3D TV US) is superior to two-dimensional transvaginal ultrasound (2D TV US) at visualising intrauterine devices and determining their position. This prospective study included 52 participants with an intrauterine device fitted, who underwent 2D TV US and 3D TV US. 2D TV US and 3D-reconstructed coronal images were reviewed by two gynaecological radiologists to assess ease of visualisation and position of the intrauterine devices. Statistical analysis was performed using Wilcoxon signed-rank, McNemar and Chi-squared tests. The inter-observer agreement was measured using Cohen's Kappa. Intrauterine device visualisation scores were significantly higher with 2D TV US compared with 3D TV US (Radiologist 1 p = visualise an intrauterine device better than 2D TV US. The 3D-reconstructed coronal image of the uterus can reliably display cases of T-arm perforation into the adjacent myometrium, which could be missed on 2D TV US images. The 3D TV US should be used in addition to 2D TV US in all cases where an intrauterine device is under evaluation.

The objective was to measure the rate of unintended pregnancies in women using levonorgestrel-releasing intrauterine systems (LNG IUSs, releasing 20 mcg LNG daily) and copper intrauterine devices (IUDs) in a typical population of IUD users and to describe associated complications. A multinational, prospective, non-interventional cohort study of new users of LNG IUS and copper IUDs was performed. Following a baseline survey, study participants and their physicians completed one follow-up questionnaire after 12 months. A multifaceted four-level follow-up procedure minimized loss to follow-up. Patient-reported outcomes were validated by the treating physicians. A total of 61,448 women with a newly inserted IUD were enrolled in six European countries between 2006 and 2012. The copper IUD cohort contained more than 30 different types. Validated 1-year follow-up information for 58,324 users between 18 and 50 years of age (70% using LNG IUS, 30% using copper IUDs) was collected. A total of 118 contraceptive failures occurred (26 LNG, 92 copper). Both types of IUD were highly effective, with overall Pearl indices of 0.06 [95% confidence interval (CI): 0.04-0.09] and 0.52 (95% CI: 0.42-0.64) for LNG IUS and copper IUDs, respectively. The adjusted hazard ratio for LNG IUS vs. copper IUDs was 0.16 (95% CI: 0.10-0.25). Tenty-one pregnancies (7 LNG IUS, 14 copper IUD) were ectopic, yielding an adjusted hazard ratio for ectopic pregnancy of 0.26 (95% CI: 0.10-0.66). The contraceptive failure rate was low with both IUDs. However, the LNG IUS was associated with a significantly lower risk of pregnancy, including ectopic pregnancy, than the copper IUDs. To our knowledge, this is the first large-scale, multinational, prospective epidemiological study to measure and compare the contraceptive effectiveness of LNG IUSs and copper IUDs during routine clinical practice. Clinicians and patients should be aware of differences in rates of unintended pregnancies and associated complications

Intrauterine devices (IUDs) are highly effective methods of contraception, but use continues to lag behind less effective methods such as oral contraceptive pills and condoms. Women who are aware of the actual effectiveness of various contraceptive methods are more likely to choose the IUD. Conversely, women who are misinformed about the safety of IUDs may be less likely to use this method. Individuals increasingly use the Internet for health information. Information about IUDs obtained through the Internet may influence attitudes about IUD use among patients. Our objective was to evaluate the quality of information about IUDs among World Wide Web sites providing contraceptive information to the public. We developed a 56-item structured questionnaire to evaluate the quality of information about IUDs available through the Internet. We then conducted an online search to identify web sites containing information about contraception and IUDs using common search engines. The search was performed in August 2013 and web sites were reviewed again in October 2015 to ensure there were no substantial changes. Our search identified >2000 web sites, of which 108 were eligible for review; 105 (97.2%) of these sites contained information about IUDs. Of sites, 86% provided at least 1 mechanism of the IUD. Most web sites accurately reported advantages of the IUD including that it is long acting (91%), highly effective (82%), and reversible (68%). However, only 30% of sites explicitly indicated that IUDs are safe. Fifty percent (n = 53) of sites contained inaccurate information about the IUD such as an increased risk of pelvic inflammatory disease beyond the insertion month (27%) or that women in nonmonogamous relationships (30%) and nulliparous women (20%) are not appropriate candidates. Among sites, 44% stated that a mechanism of IUDs is prevention of implantation of a fertilized egg. Only 3% of web sites incorrectly stated that IUDs are an abortifacient. More than a quarter of

The authors have carried out an experimental study on the reaction of an animal's organism to the presence of an open copper intra-uterine device when placed in the abdomen. The study was carried out on two groups each of 10 rabbits and two bitches. The intra-uterine device was placed in the pouch of Douglas by laparotomy, directly in one group and after contamination with genital secretions in the other. The state of the animals was checked six weeks after the initial laparotomy. Trauma caused by the operation was minimal because there were no adhesions found on the parietal peritoneum. On the other hand in experimental conditions that are very similar to those found when an intra-uterine device goes through the uterus in a human subject and involves contamination with genital secretions, in 50 per cent of cases the intra-uterine device migrated within the abdominal cavity. It was picked up by the omentum and this underwent such a strong fibrous reaction that it brought about multiple intestinal adhesions. Though the authors admit that experimental results in animals cannot be extrapolated to women, they believe that these results should be taken into consideration and that it would be imprudent to leave an intra-uterine device in the abdomen in a woman when there is proof that it has migrated, because there would then be a major risk of intestinal obstruction due to an adhesion that as formed a band.

topical hydrogel to a Spring Coil did not offer benefit. Overall, rates of perforation and pelvic inflammatory disease were low. Insertion of an IUD immediately after abortion is both safe and practical. This was true for both induced and reported "spontaneous" abortions, many of which may have been induced under clandestine circumstances. IUD expulsion rates were higher after second-trimester abortions than after earlier abortions, so delaying insertion may be advisable after later abortions. Although Copper 7 devices inserted unrelated to pregnancy may perform better than those inserted after abortion, many women who express interest in intrauterine contraception do not return for the scheduled insertion. These women may remain unprotected against unintended pregnancy. However, evidence is inadequate to compare the safety and efficacy of IUD insertion immediately after abortion vs. insertion some weeks later.

Immediate postpartum levonorgestrel intrauterine device insertion is increasing in frequency in the United States, but few studies have investigated the effect of early placement on breast-feeding outcomes. This study examined the effect of immediate vs delayed postpartum levonorgestrel intrauterine device insertion on breast-feeding outcomes. We conducted this noninferiority randomized controlled trial at the University of Utah and the University of New Mexico Health Sciences Centers from February 2014 through March 2016. Eligible women were pregnant and planned to breast-feed, spoke English or Spanish, were aged 18-40 years, and desired a levonorgestrel intrauterine device. Enrolled women were randomized 1:1 to immediate postpartum insertion or delayed insertion at 4-12 weeks' postpartum. Prespecified exclusion criteria included delivery lactogenesis, used a validated measure, and was analyzed by survival analysis and log rank test. We followed up participants for ongoing data collection for 6 months. Only the data analysis team was blinded to the intervention. We met the enrollment target with 319 participants, but lost 34 prior to randomization and excluded an additional 26 for medical complications prior to delivery. The final analytic sample included 132 in the immediate group and 127 in the delayed group. Report of any breast-feeding at 8 weeks in the immediate group (79%; 95% confidence interval, 70-86%) was noninferior to that of the delayed group (84%; 95% confidence interval, 76-91%). The 5% difference in breast-feeding continuation at 8 weeks between the groups fell within the noninferiority margin (95% confidence interval, -5.6 to 15%). Time to lactogenesis (mean ± SD) in the immediate group, 65.3 ± 25.7 hours, was noninferior to that of the delayed group, 63.6 ± 21.6 hours. The mean difference between groups was 1.7 hours (95% confidence interval, -4.8 to 8.2 hours), noninferior by log-rank test. A total of 24 intrauterine device expulsions
Unintended pregnancy persists as a major public health problem in the United States. Although lowering unintended pregnancy rates requires multiple approaches, individual obstetrician-gynecologists may contribute by increasing access to contraceptive implants and intrauterine devices. Obstetrician-gynecologists should encourage consideration of implants and intrauterine devices for all appropriate candidates, including nulliparous women and adolescents. Obstetrician-gynecologists should adopt best practices for long-acting reversible contraception insertion. Obstetrician-gynecologists are encouraged to advocate for coverage and appropriate payment and reimbursement for every contraceptive method by all payers in all clinically appropriate circumstances.

The micro-inserts used in the hysteroscopic sterilization procedure elicit a benign occlusive tissue response leading to permanent tubal occlusion. Little is known about whether immunosuppressed patients mount the immunological response necessary to ensure tubal occlusion. Theoretical concern for non-occlusion has limited the use of hysteroscopic sterilization in patients on immunosuppressive therapies. In all patient populations, if an intrauterine device is in place, it is usually removed at the time of hysteroscopic sterilization. Little is known about maintaining intrauterine devices during the 3-month period to tubal occlusion. Our patient in case 1 was a 35-year-old Hispanic woman, gravida 2, para 2002, with a history of a living donor kidney transplant. Our patient in case 2 was a 32-year-old Hispanic woman, gravida 3, para 2103, diagnosed with undifferentiated autoimmune disease. Both patients underwent hysteroscopic sterilization. In both cases, a levonorgestrel intrauterine device was in place for contraception. At the time of micro-insert placement, our patients were both on daily immunosuppressive medications, including long-term glucocorticoids. Three months after the hysteroscopic procedure, both patients had successful tubal occlusion, demonstrated by a hysterosalpingogram. Hysteroscopic sterilization in an outpatient setting is a reasonable option for sterilization in immunocompromised patients on immunosuppressive therapies. Intrauterine devices can be maintained during the procedure and during the 3-month period to tubal occlusion.

Modern hormonal contraceptives and intrauterine contraceptive devices have multiple biologic effects. Some of them may be the primary mechanism of contraceptive action, whereas others are secondary. For combined oral contraceptives and progestin-only methods, the main mechanisms are ovulation inhibition and changes in the cervical mucus that inhibit sperm penetration. The hormonal methods, particularly the low-dose progestin-only products and emergency contraceptive pills, have effects on the endometrium that, theoretically, could affect implantation. However, no scientific evidence indicates that prevention of implantation actually results from the use of these methods. Once pregnancy begins, none of these methods has an abortifacient action. The precise mechanism of intrauterine contraceptive devices is unclear. Current evidence indicates they exert their primary effect before fertilization, reducing the opportunity of sperm to fertilize an ovum.

The notion that the intrauterine contraceptive device (IUCD) has a central, as well as a local action, is examined. Although the IUCD undoubtedly has a local action, certain IUCD related side effects, e.g. galactorrhoea, bloating and premenstrual syndrome and inadequate luteal function can be explained if the IUCD has some central action. The powerful postcoital anti-fertility effect of both copper-bearing and plain plastic IUCDs probably also depends to some extent on a central action. The central action of the IUCD is probably due to initiation of reflex hypothalamic activity following intrauterine reflex stimulation. The hypothalamic response to IUCD insertion consists of release of beta-endorphin accompanied by raised levels of prolactin, vasopressin and oxytocin.

A variety of contraception options are available in addition to traditional combined oral contraceptive pills. Newer long-acting reversible contraceptive (LARC) methods such as intrauterine devices and subcutaneous implants are preferred because they do not depend on patient compliance. They are highly effective and appropriate for most women. Female and male sterilization are other effective but they are irreversible and require counseling to minimize regret. The contraceptive injection, patch, and ring do not require daily administration, but their typical efficacy rates are lower than LARC methods and similar to those for combined oral contraceptive pills.

Copper/low-density polyethylene (Cu/LDPE) nanocomposite intrauterine device (IUD) is an implanted medicinal device that must be sterilized before use. Sterilization processes act either chemically or physically, leading to a lethal change in the structure or function of organic macromolecules in microorganisms. Given the nature of their action, sterilization might also attack the macromolecules of polymers by the same mechanisms, resulting in changes in surface functional groups and in the internal structure of the polymer. If sterilization leads to changes in surface functional groups and in the internal structure of the LDPE matrix, which will influence the mechanical property and cupric ions release rate of novel Cu/LDPE nanocomposite IUDs, potential clinical application will be limited. Therefore, it is necessary to study the influence of ethylene oxide sterilization on the potential clinical application of novel Cu/LDPE nanocomposite IUDs. The influence of ethylene oxide sterilization on the internal structure, surface functional groups, mechanical property and cupric ions release rate of novel Cu/LDPE nanocomposite IUDs was studied using differential scanning calorimetry, attenuated total reflection Fourier transform infrared spectroscopy, tensile testing and absorbance measurement. Ethylene oxide sterilization did not have any influence on the internal structure, surface functional groups, mechanical property and cupric ions release rate of novel Cu/LDPE nanocomposite intrauterine devices. Ethylene oxide sterilization will not affect the potential application of novel Cu/LDPE nanocomposite IUDs.

Copper wire is the main component of a type of intrauterine device used as a contraceptive. Its contraceptive effect is attributed to the copper ions released as a result of the dissolution of copper in the uterus. Even though 10-year intrauterine device life is estimated on the basis of the dissolution rate of copper measured in vivo and in vitro, some cases of breakdown or fragmentation of the copper wire after short periods of insertion (2-3 months) have been reported. Due to the possible existence of residual stresses as a consequence of the manufacturing process, stress corrosion cracking has been previously proposed as an explanation for the early ruptures. In the present work, the susceptibility of copper wires to stress corrosion cracking in simulated uterine fluids was investigated. Results indicate that early ruptures should not be attributed to stress corrosion cracking. They could be explained by considering the increase in corrosion rate under certain conditions (pH decrease during infections; changes in the concentration of organic components along the menstrual cycle; etc.) that reduces the wire section leading to the rupture of the specimen by overloading.

The provision of effective contraception is fundamental to the practice of women's health care. The most effective methods of reversible contraception are the so-called long-acting reversible contraceptives, intrauterine devices and implants. These methods have multiple advantages over other reversible methods. Most importantly, once in place, they do not require maintenance and their duration of action is long, ranging from 3 to 10 years. Despite the advantages of long-acting reversible contraceptive methods, they are infrequently used in the United States. Short-acting methods, specifically oral contraceptives and condoms, are by far the most commonly used reversible methods. A shift from the use of short-acting methods to long-acting reversible contraceptive methods could help reduce the high rate of unintended pregnancy in the United States. In this review of long-acting reversible contraceptive methods, we discuss the intrauterine devices and the contraceptive implant available in the United States, and we describe candidates for each method, noncontraceptive benefits, and management of complications.

The purpose of this study was to examine factors that could help reduce primary perforation during insertion of a framed intrauterine device (IUD) and to determine factors that contribute in generating enough uterine muscle force to cause embedment and secondary perforation of an IUD. The objective was also to evaluate the main underlying mechanism of IUD expulsion. We compared known IUD insertion forces for "framed" devices with known perforation forces in vitro (hysterectomy specimens) and known IUD removal forces and calculated a range of possible intrauterine forces using pressure and surface area. These were compared with known perforation forces. IUD insertion forces range from 1.5 N to 6.5 N. Removal forces range from 1 N to 5.8 N and fracture forces from 8.7 N to 30 N depending upon device. Measured perforation forces are from 20 N to 54 N, and calculations show the uterus is capable of generating up to 50 N of myometrial force depending on internal pressure and surface area. Primary perforation with conventional framed IUDs may occur if the insertion pressure exceeds the perforation resistance of the uterine fundus. This is more likely to occur if the front end of the inserter/IUD is narrow, the passage through the cervix is difficult, and the procedure is complex. IUD embedment and secondary perforation and IUD expulsion may be due to imbalance between the size of the IUD and that of the uterine cavity, causing production of asymmetrical uterine forces. The uterine muscle seems capable of generating enough force to cause an IUD to perforate the myometrium provided it is applied asymmetrically. A physical theory for IUD expulsion and secondary IUD perforation is given.
Full Text Available Intrauterine device (IUD is an effective and safe contraceptive method which is commonly used worldwide. However, spontaneous or iatrogenic IUD fracture was rarely occurred during usage. We present the case about spontaneous fracture of one arm of copper IUD and the spontaneous expulsion of the broken piece in a 30-year-old woman 2 years after insertion. The patient recoursed to our clinic due to finding of a foreign body at vaginal outlet. Copper IUD was dislocated in transvaginal ultrasonographic (TVUSG examination and echogenicity of left transverse arm was not identified in transvers section.Although IUD fracture seems rarely, it must be born in mind especially when dislocation exists. Distance to fundus and its location, besides the continuity of its echogenicity and integrity should be observed during routine controls.

The aim of this study was to compare the pain-relieving effect of intracervical lidocaine gel with that of lidocaine spray or no local anaesthesia in decreasing pain during insertion of the intrauterine contraceptive device (IUCD). In a prospective multicentre non-randomised comparative study design, 420 women were divided into three groups of 140 and fitted with the same type of IUCD. Group 1 received cervical lidocaine gel, group 2 received cervical lidocaine spray and group 3 received no topical anaesthesia. A visual analogue scale was used to measure the degree of pain experienced. There were no significant differences between the three groups with regard to baseline characteristics such as age and number of deliveries. Significantly less pain was felt during cervical traction in women using a local anaesthetic. However, there were no significant differences in pain due to IUCD insertion. Application of a local anaesthetic decreased the pain resulting from cervical traction but not that resulting from IUCD insertion.

To reduce such side effects as pain and bleeding caused by copper-containing intrauterine device (Cu-IUD), a novel medicated intrauterine device, which is coated with an indomethacin (IDM) delivery system on the surface of copper/low-density polyethylene (Cu/LDPE) composite intrauterine device, has been proposed and developed in the present work. The IDM delivery system is a polyelectrolyte multilayer film, which is composed of IDM containing chitosan and alginate layer by layer, is prepared by using self-assembled polyelectrolyte multilayer method, and the number of the layers of this IDM containing chitosan/alginate multilayer film can be tailored by controlling the cyclic repetition of the deposition process. After the IDM containing chitosan/alginate multilayer film is obtained on the surface of Cu/LDPE composite intrauterine device, its release behavior of both IDM and cupric ion has been studied in vitro. The results show that the release duration of IDM increase with the increasing of thickness of the IDM containing chitosan/alginate multilayer film, and the initial burst release of cupric ion cannot be found in this novel medicated Cu/LDPE composite IUD. These results can be applied to guide the design of novel medicated Cu-IUD with minimal side effects for the future clinical use. Copyright © 2013 Elsevier B.V. All rights reserved.

Conclusion: Either copper intrauterine device or injectable contraceptive usage for more than 9 months results in significant decrease in endometrial proliferative or cell mitotic activity. While copper IUD has no effect on serum estradiol or progesterone levels, DMPA usage increased serum progesterone level with no effect on serum estradiol.

YouTube's online archive of video testimonials related to health information are more commonly viewed than those developed by clinicians and professional groups, suggesting the importance of the patient experience to viewers. We specifically sought to examine the accuracy of information on, and projected acceptability of, the intrauterine device (IUD) from these YouTube testimonials. We searched YouTube for videos about individual uploaders' IUD experiences, using the search terms 'intrauterine device', 'IUD', 'Mirena' and 'Paragard'. Given interest in user testimonials, we excluded professional and instructional videos belonging to commercial or non-profit entities. Two reviewers independently analysed the videos using a structured guide, with attention to inaccurate information. Of 86 identified videos, four videos featured clinicians and were excluded; 62 met inclusion criteria. Interrater agreement on IUD portrayal was good (K=0.73). Young (mean age 25, range 19-38, years), white (75%), nulliparous (61%) women primarily uploaded content. Most described placement of the LNG-IUS (65%), were posted within 1 month of insertion (45%), and mentioned side effects (66%) - bleeding, pain, and partner sensation of the strings. About one-third of videos contained inaccurate information (34%) and were thought to project an overall negative experience (30%). Videos portraying IUDs negatively were associated with inaccurate information and/or mention of side effects. While one-third of IUD user testimonials on YouTube contained inaccurate information, the majority of IUD experiences were perceived by our study viewers to be positive. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To assess the incidence of visible strings of intrauterine contraceptive devices (IUDs) after postplacental insertion following vaginal or caesarean delivery and to establish a management protocol of follow-up visits when strings are not visualised. This was a prospective study of a cohort of 348 women who underwent postplacental insertion of Copper-T 380A IUDs following vaginal or caesarean delivery, conducted at a hospital in New Delhi, India. Women were followed up at 6 weeks, 3, 6 and 12 months after IUD insertion and were questioned about IUD expulsion or removal at each visit. The cervix was inspected to visualise the IUD strings. All women whose IUD strings could not be visualised at the cervical os at any given follow-up were identified. We analysed the cumulative incidence of visible strings and of procedures performed to locate the IUD when strings were not visible. At 1 year follow-up, the IUD was in situ in 313/348 (89.9%) women. There were eight (2.3%) expulsions and 15 (4.3%) IUD removals. Among women with IUDs in situ, the strings were not visible in 73 (21%) cases. Pelvic ultrasound confirmed intrauterine position of the IUDs in these cases. At 1 year, string visibility was significantly lower after intra-caesarean insertions as compared to vaginal insertions (72.4% vs 98.1%; pVisualisation of strings after postplacental vaginal insertion is more common than after intra-caesarean insertion. Pelvic ultrasonography can be used to verify the presence of the device in cases of missing strings. Published by the BMJ Publishing Group Limited.

The parasitism by Trichomonas vaginalis is complex and in part is mediated by cytoadherence accomplished via five surface proteins named adhesins and a glycoconjugate called lipophosphoglycan (TvLPG). In this study, we evaluated the ability of T. vaginalis isolates to adhere to cells, plastic (polystyrene microplates), intrauterine device (IUD), and vaginal ring. Of 32 T. vaginalis isolates, 4 (12.5%) were strong adherent. The T. vaginalis isolates TV-LACM6 and TV-LACM14 (strong polystyrene-adherent) were also able to adhere to IUD and vaginal ring. Following chemical treatments, results demonstrated that the T. vaginalis components, lipophosphoglycan, cytoskeletal proteins, and surface molecules, were involved in both adherence to polystyrene and cytoadherence. The gene expression level from four adhesion proteins was highest in trophozoites adhered to cells than trophozoites adhered to the abiotic surface (polystyrene microplate). Our data indicate the major involvement of TvLPG in adherence to polystyrene, and that adhesins are important for cytoadherence. Furthermore, to our knowledge, this is the first report showing the T. vaginalis adherence to contraceptive devices, reaffirming its importance as pathogen among women in reproductive age.
Full Text Available Actinomycosis is a rare, chronic suppurative infection caused by the Gram-positive anaerobic filamentous bacterium, Actinomyces Israeli. In most cases, the diagnosis is made postoperatively because of its unusual clinical presentation. Abdominal actinomycosis is the second most common site of the disease and may mimic abdominal cancer, inflammatory bowel disease or diverticulitis. The abdominal-pelvic form of this disease mostly results from the prolonged use of an intrauterine device. We report a rare case of combined intra- and extra-abdominal actinomycosis mimicking urachal tumor that was diagnosed by computed tomography, which presented as two tender abdominal palpable masses following long-term intrauterine device use. The disease was confirmed by postoperative histopathologic examination, which revealed sulfur granules microscopically, and was successfully treated by complete surgical resection following a period of appropriate antibiotic treatment.

This study was conducted to investigate the effects of a 1% lidocaine paracervical block on perceived patient pain during intrauterine device (IUD) insertion. We randomized 50 women undergoing IUD insertion to receive either a 10-mL 1% lidocaine paracervical block or no local anesthetic before IUD insertion. Women marked their pain on a 100-mm visual analogue scale (VAS) (0 mm = no pain, 100 mm = worst pain possible) at various points of the procedure (speculum insertion, tenaculum placement, paracervical block administration, IUD insertion and 5 min postprocedure). Twenty-six women received the paracervical block before IUD insertion, and 24 received no local anesthesia. Groups were similar in age, parity, ethnicity, education and complications. Women who received the paracervical block reported a median VAS score of 24.0 mm with IUD insertion, and women who did not receive local anesthetic reported a median VAS score of 62.0 mm with IUD insertion; p=.09. Compared with no anesthetic, a 1% lidocaine paracervical block did not result in a statistically significant decrease in perceived pain with IUD insertion. Copyright © 2012 Elsevier Inc.

The purpose of this work was to study the continuation rate of intrauterine device (IUD) copper in a nulliparous population. A prospective study in a family planning centre including nulliparous patients between January and December 2012. A total of 83 nulliparous patients had IUD copper insertion and 11 patients were excluded because they were lost to follow-up. Finally, 72 nulliparous patients were included in the study. Continuation rate after one-year follow-up was 90.3% (65/72). Satisfaction rate of patient was high (93.8%). Menstruation amount was increased for 84% (55/65) patients, but 75% (41/55) did not report any inconvenience about this. Dysmenorrhea were increased for 80% (52/65) patients, but 58% (30/52) were not troubled by this. Continuation rate of IUD copper was high (90%) after one-year follow-up in nulliparous women. Tolerance was also good for evaluated patients. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

To evaluate the determinants of intrauterine device (IUD) use and reasons for choosing IUDs over other reversible contraceptive methods. Descriptive statistics and multinomial logistic regression were used to assess multiple factors associated with IUD use and the use of other reversible methods in the United States. Not applicable. Women at risk of pregnancy from the 2006 to 2008 National Survey of Family Growth and a 2004 Guttmacher Institute survey. None. Sociodemographic and reproductive characteristics, family background, and health insurance coverage. IUD use was positively associated with women's parity and the highest education level of respondent's mother; it was less common among women who had ≥4 sexual partners in the last 12 months and those who were widowed, divorced, or separated. IUD users reported pregnancy prevention, provider recommendation, and no interruption of sex as the most important reasons for choosing the method and reported a high level of satisfaction. IUD users differed substantially from users of other reversible contraceptives. IUD use was especially uncommon among nulliparae. Most current IUD users were satisfied with their choice.

Globally, endometrial cancer is the sixth leading cause of female cancer-related deaths. Non-atypical endometrial hyperplasia (EH), has a lifetime progression rate to endometrial cancer ranging from less than 5%, if simple without atypia, to 40%, if complex with atypia. Site specific, long-acting intrauterine devices (IUDs) provide fertility sparing, progestin-based EH medical management. It is unclear which IUD is most beneficial, or if progesterone sensitizing metformin offers improved outcomes. For resolution, PubMed searches for "Mirena" or "Metformin," "treatment," "endometrial hyperplasia," or "stage 1 endometrial cancer," were performed, yielding 33 articles. Of these, 19 articles were included. The 60 mg high-dose frameless IUD/20 mcg levonorgestrel has achieved sustained regression of Grade 3 endometrial intraepithelial neoplasia for 14 years. Case series on early stage endometrial cancer (EC) treatment with IUDs have 75% or greater regression rates. For simple through complex EH with atypia, the 52 mg-IUD/10-20 mcg-LNG-14t has achieved 100% complete regression in 6-months. Clearly, IUDs have an outcome advantage over oral progestins. However, studies on metformin for EH, and of progestins or metformin for early stage EC management are underpowered, with inadequate dose ranges to achieve significant differences in, or optimal outcomes for, the treatment modalities. Therefore, outcomes from the feMMe trial for the 52 mg-IUD/10-20 mcg-LNG-14t and metformin will fill a gap in the literature.

Intrauterine contraceptive device (IUCD) is relatively safe but still with some serious risks. Uterus perforation is rare and would be fatal. A case of Cu-7 IUCD invading into the sigmoid colon through uterine perforation caused by a pelvic blunt trauma was presented. Our case showed that uterus perforation by an IUCD could induce utero-sigmoid fistula which is likely to be missed. Imaging is required when the patients with IUCD present abdominal pain, particularly with a history of trauma.

As the popularity of long-acting reversible contraception increases, so does the need for accurate data on method continuation in diverse clinical settings. We determined 2-year continuation rates for the levonorgestrel 52-mg intrauterine device, the copper T380A intrauterine device, and the 68-mg etonogestrel contraceptive implant in an academic healthcare system with mixed-payer reimbursement. The purpose of this study was to examine the proportion and characteristics of women who continue intrauterine device and implant use to 2 years and to relate continuation to device type when controlling for patient characteristics. This retrospective chart review assessed University of Utah Healthcare System patients who had an intrauterine device or contraceptive implant inserted between January 1, 2004, and December 31, 2012. We identified users and dates of insertions and removals by querying billing, medication, and procedural data in the Electronic Data Warehouse. Multivariable Poisson regression was conducted to estimate incidence risk ratios and to relate the probability of 2-year continuous use to device type. Data on 8603 device insertions were obtained with the following distribution: levonorgestrel 52-mg intrauterine devices (6459; 75.1%), copper T380A intrauterine devices (1136; 13.2%), and 68-mg etonogestrel implant (1008; 11.7%). Two-year continuation rates were 77.8%, 73.1%, and 75.9%, respectively. There was no statistical difference in 2-year continuation between levonorgestrel 52-mg intrauterine device users (adjusted risk ratio, 1.1; 95% confidence interval, 1.0-1.1) and 68-mg etonogestrel implant users (adjusted risk ratio, 1.1; 95% confidence interval, 1.0-1.1) compared with copper device users, after we controlled for age, Hispanic ethnicity, payer type, and year of insertion. Older-age, self-pay, or public payer insurance (reference commercial payer) and Hispanic ethnicity were associated with 2-year continuation. Three-quarters of women with an

Materials and methods: This paper is based on studies that examined the differences in uterine volume and cavity size, related to age and parity, and on original clinical research data and practical experience with frameless copper IUDs, as well as on literature data on the IUD–endometrial cavity relationship of conventional IUDs, with special reference to side effects and user discontinuation. Results: The mean transverse diameter in nulliparous and parous women is significantly less than the length of the transverse arm of the TCu380A IUD (ParaGard, Duramed, NY, USA or the levonorgestrel intrauterine system (Mirena, Bayer, Germany. Small, frameless, flexible, and unidimensional copper IUDs appear to be well tolerated, with less impact on menstrual bleeding, resulting in low discontinuation rates when compared with standard-size conventional IUDs, which often result in increased expulsion rates, complaints of pain and erratic or increased menstrual bleeding, and subsequent high rates of
Full Text Available Introduction: Intrauterine device (IUD is the most common reliable, effective and reversible contraceptive method used worldwide and in areas with high growth rate is of particular importance. IUD insertion is associated with high anxiety in most people that causes pain and discomfort. The aim of this study was to determine the effects of aromatherapy on anxiety and pain caused by IUD insertion. Methods: This study was conducted on 106 women in a health care center located in Ardebil, Iran. Participants were divided into two groups by randomized blocks of 4 and 6. In the experimental group lavender scent was inhaled and in the control group the placebo was inhaled 30 minutes before IUD insertion. The anxiety of the participants was measured by Spielberger questionnaire, and the pain of IUD insertion was measured immediately after the insertion using visual analog scale (range 0-10. Results: The mean score (standard deviation of anxiety before intervention was 43.2 (9.2 in the experimental group that decreased after intervention to 39.0 (10.5 (p < 0.001, while this score was 42.2 (9.0 and 41.5 (8.4 before and after the intervention in the control group (p = 0.21. Mean differences of anxiety in both groups was statistically significant (p < 0.001. The pain score after intervention did not show significant difference between two groups (p = 0.51. Conclusion: Aromatherapy with lavender inhalation was effective in decreasing anxiety in IUD procedure, and this method can be used in health care centers as complementary treatments.

Full Text Available Background: The intrauterine device (IUCD is a highly effective and safe method of contraception. Prevention of unwanted pregnancies has made its use a matter of national priority in certain countries.Despite numerous advantages and suitability the uptake of the IUCD is poor. Patients in South Africa seem to lack knowledge regarding this contraceptive. Objectives: The aim of this study was to determine the quantity and quality of knowledge of the IUCD, and to evaluate its acceptability for future use. Methods: A prospective cross-sectional study was conducted at Pelonomi Tertiary Hospital. 201 consecutive patients were interviewed using structured questionnaires. Results: Awareness of the IUCD was found in almost half (49%, n=95 of our patients. Its use was very low, with only one patient having used it before. Overall qualitative knowledge was poor, even among those that were aware of the IUCD. There was a significant association between level of education and knowledge, with patients having passed Grade 12 or higher significantly more likely to have knowledge of the IUCD than those at lower levels (RR 1.57, 95% CI 1.18-2.08. Forty-five percent (n=86 of patients indicated a desire for future IUCD use. Conclusion: Despite the availability of the IUCD in South African clinics and hospitals, its uptake is still poor. Awareness of this method seemed to have improved over the past few years, but the qualitative knowledge still lacks considerably. Education plays a major role in the knowledge of contraception and better educational aids in all facilities will increase its use and reduce unwanted pregnancies.

We assessed the risk of tubal pregnancy among women who (1) were currently using an intrauterine device (IUD) and (2) had discontinued IUD use while still sexually active and at risk of pregnancy using data from a multicentre case-control study of married women conducted in Indonesia. Cases were 560 women diagnosed with histologically confirmed ectopic pregnancy from April 1989 to August 1990 at any one of 11 participating hospitals. Controls were 1120 non-pregnant women similar in age and place of residence to the cases. In-person interviews were conducted to collect information regarding current and past contraceptive use as well as other demographic and personal characteristics. Women currently using an IUD were considerably less likely than women not currently using contraception, but more likely than users of hormonal or surgical means of contraception, to develop a tubal pregnancy. Women who had discontinued using an IUD had a 70% subsequent increase in risk of tubal pregnancy (adjusted RR = 1.7, 95% Cl: 1.1-2.5) relative to women who had never used an IUD. This increase in risk was most pronounced in women who reported multiple episodes of IUD use and, to a lesser extent, in women with a long (> 3 year) duration of IUD use. The associations we observed are similar to those previously reported in studies conducted in developed countries. The results are of particular interest because this study was conducted in a location in which the Dalkon Shield IUD was never available, and among a population of married, gravid women for whom IUD use is generally considered most appropriate.

To evaluate whether 550 mg oral naproxen sodium given 1 hour before intrauterine device (IUD) insertion is effective for pain relief as compared with placebo. This was a randomized, double-blind, placebo-controlled trial. The primary outcome was pain with IUD insertion measured on a 100-mm visual analog scale (VAS). Our sample size was calculated to detect a 15-mm difference in VAS scores with 80% power (α=0.05). Secondary outcomes included pain with tenaculum placement, uterine sounding, and 5 and 15 minutes postinsertion. A total of 118 women were enrolled and analyzed (58 in the naproxen sodium arm, 60 in the placebo arm, 97% nulliparous) between May 11, 2015, and March 25, 2016. There were no differences in baseline demographics or reproductive characteristics between arms. There were no differences in median VAS pain scores for the primary outcome of pain with IUD insertion between the naproxen sodium arm compared with the placebo arm (69 compared with 66 mm, P=.89). There were no differences in the secondary outcomes of median VAS pain scores with tenaculum placement (37 compared with 32 mm, P=.97) or uterine sounding (60 compared with 58 mm, P=.66). However, median pain scores postprocedure were lower in the naproxen arm as compared with the placebo arm: 17 compared with 26 mm (P=.01) at 5 minutes and 13 compared with 24 mm (P=.01) at 15 minutes postinsertion. Oral naproxen sodium does not reduce pain with IUD insertion but does reduce pain after insertion and should be considered as a premedication.

Background The appropriate choice of a contraceptive method has been a major issue in reproductive health research. Cu T intrauterine device (Cu T IUD) has been introduced as one of the most effective contraceptive methods in the world, however, the relationship between prior use of Cu T IUD and secondary infertility has not been evaluated in Iran. To examine the association of Cu T-380A IUD and secondary infertility in Iran. Materials and Methods A retrospective cohort study was conducted from December 2010 to September 2011 in the Research and Clinical Center for Infertility, Shahid Sadoughi University of Medical Sciences, Yazd, Iran. A total of 750 married women (15-49 years old) with at least one parity, whom were referred to four educational healthcare centers of Shahid Sadoughi University of Medical Sciences, were selected as participants. They were divided into two groups (case and control) based on previous history of using Cu T-380A IUD. Data were gathered using a standard reliable questionnaire along with a face-to-face interview and were analyzed with descriptive and analytical (χ²) tests. Results Mean period of Cu T-380A IUD usage in the case group was 57.46 ± 47.74 months and mean time length from Cu T-380A IUD removal to pregnancy was 14.87 ± 5.18 months in this group. We observed no relationship between the use of Cu T-380A IUD and frequency of secondary infertility (3.5% in the case group versus 2.7% in the control group, P=0.52). Conclusion Given the relatively large sample size studied here, it is unlikely that Cu T-380A IUD results in secondary infertility and may be used by Iranian women as a safe contraceptive method.

In this study we aimed to evaluate the effect of intrauterine devices (IUDs) on cervico-vaginal colonization. Cervico-vaginal samples of 96 patients with vaginal discharge were included in the study. Microscopic evaluation, bacteriological and fungal culture, and antigen testing for Chlamydia trachomatis using an immunochromatographic test method were performed. Trichomonas vaginalis was not detected by wet mount examination. Gram smear revealed that seven patients (7.3%) had Candida spp. and five (5.2%) had clue cell. Of the 96 swabs tested for conventional culture, pathogenic microorganisms were isolated from 24 patients. While Neisseria gonorrhoeae was not found in any of the sample, five (5.2%) were positive for Gardnerella vaginalis. Five (5.2%) were positive for C. trachomatis antigen, while three positivity only for C. trachomatis antigen, one had G. vaginalis additionally, and the other had a mixed infection. Chlamydial antigen positivity was higher among women over 30 years of age (p = 0.157). Increase in polymorphonuclear leukocytes (PNL) was detected 40% and 35.2% of samples, positive and negative, for chlamydial antigen, respectively (p = 1.000). Among IUD+ cases, increase in PNL, fungal elements, E. coli and Gram-positive bacteria and decrease in Lactobacillus spp. were observed, compared to IUD-cases. No statistically significant relationship was detected between IUD and chlamydial antigen with the reported rates of 4.8% and 5.6% for IUD+ or IUD-, respectively (p > 0.05). Statistically significant relationship was not detected between IUD and cervico-vaginal colonization. More comprehensive studies using specific test methods should be conducted to better understand the relationship.

We explored influences on decision making about intrauterine device (IUD) use among women in the Women's Health Project (WHP), managed by Population Services International in Madagascar. We conducted six small group photonarrative discussions (n=18 individuals) and 12 individual in-depth interviews with women who were IUD users and nonusers. All participants had had contact with WHP counselors in three sites in Madagascar. Data analysis involved creating summaries of each transcript, coding in Atlas.ti and then synthesizing findings in a conceptual model. We identified three stages of women's decision making about IUD use, and specific forms of social support that seemed helpful at each stage. During the first stage, receiving correct information from a trusted source such as a counselor conveys IUD benefits and corrects misinformation, but lingering fears about the method often appeared to delay method adoption among interested women. During the second stage, hearing testimony from satisfied users and receiving ongoing emotional support appeared to help alleviate these fears. During the third stage, accompaniment by a counselor or peer seemed to help some women gain confidence to go to the clinic to receive the IUD. Identifying and supplying the types of social support women find helpful at different stages of the decision-making process could help program managers better respond to women's staged decision-making process about IUD use. This qualitative study suggests that women in Madagascar perceive multiple IUD benefits but also fear the method even after misinformation is corrected, leading to a staged decision-making process about IUD use. Programs should identify and supply the types of social support that women find helpful at each stage of decision making. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available Pyometra is the accumulation of pus in the uterine cavity, thus streaching its walls and thinning and enlarging the uterus. This change is characteristic of the senium period of life, when the uterus is atrophie with a stenotic cervical canal. It most frequently occurs as a result of secondary infection of the cancerogenic tissue of the uterus and additional stenosation and clogging up of cervical canal by a malignant process. Apart from carcinomas of the body and uterus cervix, pyometra less often can occur in other illnesses such as senile endometritis and senile colpitis. As pyometra most frequently occurs in uterine carcinomas, in detection of this state, we must think of malignancy and direct our examination to this direction. In this paper we present a patient in whom pyometra developed because she carried an intrauterine device for forty years that resulted in chronic endometritis. The main symptoms for which the patient was admited to hospital were abdominal pain and intensive suppurative vaginal excretion a month after removal of intrauterine device. The diagnosis of pyometra was made by gynaecological and ultrasound examinations, and also on the basis of gynecological and ultrasound examinations one month after chronic endometritis was confirmed. On the basis of this finding we suspected that chronic endometritis was caused by this state. By cytological, PAP and histopathological examinations of samples obtained by explorative curettage and biopsy of the uterine cervix, malignant changes were eliminated a possible cause. By laboratory analysis and bacteriological examination of the uterine cavity and vaginal excretion, inflammatory changes of the uterine mocous membrane were confirmed as a cause of the pyometra. This conditions was due to carrying the intrauterine device for more decades. The therapy consisted of dilatation of the cervical canal and evacuation of accumulated suppurative contents and irrigation of uterine cavity with 3

Perforation of the uterus is a recognized complication associated with the use of an intrauterine contraceptive (IUCD). However, migration of an IUCD into the bladder, with or without stone formation, is exceptionally rare. We report the case of a patient with a displaced IUCD that acted as a nidus for bladder lithiasis. (author)

Increasing use of long-acting methods of contraception, such as intrauterine devices (IUDs), has been recognized as a promising strategy to reduce the incidence of unintended pregnancy. While men may play an important role in promoting or discouraging contraceptive use, very little research has examined men's knowledge of and attitudes toward IUDs. We used data from the 903 men included in the 2009 National Survey of Reproductive and Contraceptive Knowledge to examine their awareness and knowledge of IUDs and other contraceptive methods by several individual-level characteristics. Men's awareness and perceived knowledge of IUDs is low in comparison to condoms and birth control pills. Men's perceived knowledge of IUDs was lower than their objective knowledge, as measured by true/false questions about IUDs, suggesting that men may be more knowledgeable of IUDs than they perceive. In the multivariate models, men who were uninsured [adjusted odds ratio (AOR), 0.4; 95% confidence interval (CI), 0.2-0.6], identified as Christian (AOR, 0.6; 95% CI, 0.3-1.0) and who had never had a sexual health visit (AOR, 0.6; 95% CI, 0.4-1.0) were less likely to have heard of IUDs. Among men who had heard of the method, Hispanic men were less likely (AOR, 0.2; 95% CI, 0.1-0.5) to be more knowledgeable of the method. Young men report low awareness of IUDs in comparison to other methods, and this varies by demographic characteristics including health insurance status. Family planning programs should consider targeted knowledge promotion for young men, with a focus on contraceptive methods besides condoms and oral contraception. Male partners are influential in contraceptive use, yet little research has examined their IUD knowledge. Our findings indicate that healthcare providers may play important role in increasing young men's knowledge of contraceptive methods, including IUDs. This study highlights the need to better incorporate young men into contraception research and programs

It is widely agreed that the practices of clinicians should be based on the best available research evidence, but too often this evidence is not reliably disseminated to people who can make use of it. This "know-do" gap leads to ineffective resource use and suboptimal provision of services, which is especially problematic in low- and middle-income countries (LMICs) which face greater resource limitations. Family planning, including intrauterine device (IUD) use, represents an important area to evaluate clinicians' knowledge and practices in order to make improvements. A questionnaire was developed, tested and administered to 438 individuals in China (n = 115), Kazakhstan (n = 110), Laos (n = 105), and Mexico (n = 108). The participants responded to ten questions assessing knowledge and practices relating to contraception and IUDs, and a series of questions used to determine their individual characteristics and working context. Ordinal logistic regressions were conducted with knowledge and practices as dependent variables. Overall, a 96 % response rate was achieved (n = 438/458). Only 2.8 % of respondents were able to correctly answer all five knowledge-testing questions, and only 0.9 % self-reported "often" undertaking all four recommended clinical practices and "never" performing the one practice that was contrary to recommendation. Statistically significant factors associated with knowledge scores included: 1) having a masters or doctorate degree; and 2) often reading scientific journals from high-income countries. Significant factors associated with recommended practices included: 1) training in critically appraising systematic reviews; 2) training in the care of patients with IUDs; 3) believing that research performed in their own country is above average or excellent in quality; 4) being based in a facility operated by an NGO; and 5) having the view that higher quality available research is important to improving their work.

To estimate the acceptance rate and trend of Intrauterine Contraceptive Device (IUCD) use in Enugu, Nigeria A review of all new acceptors of intrauterine contraceptive device (IUCD) over a nine year period (1999-2007). A total of 133,375 clients were seen at the UNTH family planning clinic between 1999 and 2007. Out of 6,947 users of IUCD, during the period, 1,659 were new acceptors. The IUCD acceptance rate was 5.21%. Majority of the clients (29.7%) were aged 40 years and above. Eight hundred and forty seven (51.4%) had attained post secondary education. Majority of the clients (99.4%) were married . Twenty-six percent (26.0%) had completed their desired family size. Majority 1,359 (82.4%) did not use any method contraception prior to IUCD insertion. The commonest complication was menorrhagia (5.8%) and this was responsible for removal in 3.0% of cases. Eight (0.5%) and nine (0.6%) requested for removal for fear of causing cancer and migration to the brain or heart respectively. Two (0.1%) became pregnant while having the IUCD in-situ. Majority of the clients (50.5%) had the knowledge of lUCD through friends. This study has shown that IUCD (TCU 380A) is both safe and effective in Enugu, Nigeria. Its use is for both child spacing and limiting family size.

Methods: Nulliparous and adolescent women, 25 years of age or younger, using the frameless copper IUD or the frameless LNG-releasing intrauterine system (IUS, were selected from previous studies and a current multicenter post-marketing study with the frameless copper IUD. The small copper-releasing GyneFix® 200 IUD consists of four copper cylinders, each 5 mm long and only 2.2 mm wide. The frameless FibroPlant® LNG-IUS consists of a fibrous delivery system releasing the hormone levonorgestrel (LNG-IUS. The main features of these intrauterine contraceptives are that they are frameless, flexible, and anchored to the fundus of the uterus. Results: One hundred and fifty-four nulliparous and adolescent women participated in the combined study. One pregnancy occurred with the GyneFix 200 IUD after unnoticed early expulsion of the device (cumulative pregnancy rate 1.1 at one year. Two further expulsions were reported, one with the GyneFix 200 IUD and the other with the FibroPlant LNG-IUS. The cumulative expulsion rate at one year was 1.1 with the copper IUD and 2.2 with the LNG-IUS. The total discontinuation rate at one year was low (3.3 and 4.3 with the copper IUD and LNG-IUS, respectively and resulted in a high rate of continuation of use at one year (96.7 with the copper IUD and 95.7 with the LNG-IUS, respectively. Continuation rates for both frameless copper IUD and frameless LNG-IUS remained high at 3 years (>90%. There

Use of the intrauterine device (IUD) in the United States has recently increased. New evidence for women with employer-sponsored health insurance permits analysis of variation and trends in such use. A retrospective analysis of annual IUD insertion rates between 2002 and 2008 was conducted by evaluating claims from the MarketScan® Commercial Research Databases for US women insured by plans that covered IUD insertions. Estimates were weighted to be nationally representative. IUD insertion rates increased from 1.6/1000 women of reproductive age to 9.8/1000 over 2002-2008 and varied substantially by state. Insertion rates of the levonorgestrel-releasing intrauterine system (LNG-IUS) increased from 0.4/1000 to 7.7/1000, whereas the insertion rates of copper T380A IUD (copper IUD) increased from 0.6/1000 to 1.5/1000. IUD insertions, which are most common among women aged 25-34 years, increased at roughly the same rate across all age groups. The sixfold increase in IUD insertion rates between 2002 and 2008 was accompanied by an increase in the share IUD use with the LNG-IUS from 40% to 85%. Substantial geographic and age variations existed. Published by Elsevier Inc.
Full Text Available Isolated abdominal wall actinomycosis in the presence of an intrauterine contraceptive device (IUCD is extremely rare and only six such cases have been reported in the literature. We report a case where clinical and radiological examinations revealed a pseudotumor within the anterior abdominal wall. After being lost to follow-up, the patient presented two years later with the enlargement of the mass. The mass including the affected anterior abdominal wall was completely excised. The diagnosis of actinomycosis was established postoperatively by histopathological examination. Further questioning concerning her gynecological history revealed long-term use of the same IUCD. Surgical excision of the actinomycotic pseudotumour and removal of the IUCD followed by antibiotic therapy resulted in the full recovery of the patient.

Copper/indomethacin/low-density polyethylene (Cu/IDM/LDPE) nanocomposite was prepared as a novel material for intra-uterine device (IUD). IDM release profile of the nanocomposite was investigated by using spectrophotometer. The results show that IDM release rate of Cu/IDM/LDPE nanocomposite is higher in simulated uterine solution than that in methanol, confirming that the release process of IDM is dominated mainly by pore diffusion. The decrease in copper particle size and the increase in copper mass content all accelerate IDM release, indicating that IDM release rate can be adjusted by changing copper loading or copper particle size. The surface of the incubated nanocomposite was characterized by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray microanalysis. A few deposits composed of P, Cl, Ca, Cu and O were observed on the nanocomposite surface, which may be related to the presence of IDM particles with large particle size.

To investigate the efficacy of the insertion of intrauterine contraceptive device (IUCD) tied up with nylon threads for the treatment of cervical stenosis after conization. Dilatation of the cervical canal and insertion of IUCD tied up with nylon threads was performed in four patients with symptomatic cervical stenosis after conization. After three courses of regular menstruation, the IUCD with nylon threads was removed. Total relief of symptoms was achieved in all four patients without any management-related complications. There was no evidence of recurrent cervical stenosis at follow-up in any of the patients. Detention of nylon threads tied up to IUCD provides an easy and reliable conservative management technique for post-conization cervical stenosis.

22 patients complaining of primary menorrhagia or menorrhagia associated with an intrauterine device (I.U.C.D.) were studied in a double blind trial with crossover of ethamsylate and placebo. Acutal menstrual blood-losses were calculated from the iron content of used sanitary material during one pre-trail menstrual period and four trial menstrual periods, during which patients received ethamsylate ("Dicynene") treatment during two menstrual cycles and placebo during two cycles. During ethamsylate treatment the mean menstrual blood-loss was reduced by 50% in patients with primary menorrhagia and by 19% in patients with an I.U.C.D. This difference between the two groups is probably accounted for by the differing values of initial blood-loss which was significantly higher in the group with primary menorrhagia. Tampon usage and the duration of bleeding were not significantly altered by ethamsylate treatment. Reported side-effects, which were not serious, were equally common during ethamsylate and placebo treatment.

Endometriosis can affect up to 10% of women of reproductive age, in a wide range of clinical presentations that vary from mild to severe or deep endometriosis. Deep endometriosis can affect the urinary tract in 1-5% to 15-25% cases. Even though deep endometriosis' surgeries are usually complex with higher rate of complications, conservative management is not always considered as an option because of its high failure rates. This paper describes two cases of deep endometriosis with ureteric involvement (hydronephrosis) treated conservatively with a double-pigtail stent plus a Levonorgestrel intrauterine device, after conservative surgery, who remained symptom free with no evidence of recurrence at 3 years follow-up, avoiding radical high-risk surgery. Impact statement Several treatments have been described for endometriosis. From a symptomatic perspective, conservative medical management has been proposed with a variable response. Concerning deep endometriosis (affecting the urinary or digestive tract), the definitive treatment has always been thought to be radical surgery. However, this can lead to several complications. To illustrate a possible more conservative approach this paper describes two cases of deep infiltrating endometriosis affecting the ureter, treated conservatively with a temporary pigtail ureter stent plus a Levonorgestrel intrauterine device. The management demonstrates that, in a selected population, conservative treatment solves the urinary disease avoiding the surgical complications and, what is more, improving patients' symptoms in a permanent way. Further prospective studies are needed to confirm whether the introduction of this management in clinical practice would reduce the need for surgery thereby, avoiding high-risk surgery and improving the success rate of conservative management.

To assess the endometrial response rates to treatment with the levonorgestrel intrauterine device in post-menopausal women with atypical hyperplasia/endometrial intraepithelial neoplasia and grade 1 endometrioid (AH/EC) endometrial carcinoma who are not surgical candidates. Chart review was undertaken of patients with AH/EC who underwent levonorgestrel intrauterine device insertion by a gynecologic oncologist within two academic health systems between 2002 and 2013. When available, tissue blocks were evaluated with immunohistochemical staining for progesterone receptor expression. A total of 41 patients received treatment for AH/EC with the levonorgestrel intrauterine device. Follow up sufficient to assess response occurred in 36 women (88%). Complete response was documented in 18 of 36 women (50%), no response in 8 patients (22%), partial response in 3 women (8%) and progression of disease in 7 patients (19%). Four of 18 patients with complete response (22%) later experienced relapse of hyperplasia or cancer. Four patients (10%) died during the study period: none had evidence of metastatic disease and 1 of the 4 woman died of perioperative complications following hysterectomy for stage I disease. Patients responding to treatment had significantly lower progesterone receptor expression on post-treatment biopsies. Intrauterine levonorgestrel is a viable treatment option for post-menopausal women with AH/EC who are poor candidates for standard surgical management. The response rate in this series is similar to published reports in premenopausal patients and includes cases of disease recurrence following conversion to benign endometrium.

Intrauterine devices (IUDs) are effective, reversible forms of contraception with high patient satisfaction and continuation. IUDs can be safely used by most women and should be considered the first-line method of contraception for all women. This descriptive review will discuss the clinical issues associated with IUDs - including management of side effects, noncontraceptive uses and insertion and removal. When the burdens of cost are removed, women are more likely to select and IUDs. Health policy changes that increase insurance coverage for contraception will improve access to IUDs. IUDs remain an underutilized form of contraception in USA and efforts to improve availability and access to long-acting reversible contraception methods is needed to optimize their use.

To compare discontinuation rates and incidence of repeat pregnancy within 1 year among young mothers choosing postplacental intrauterine devices (IUDs) versus postpartum contraceptive implants. We enrolled a prospective cohort of postpartum adolescents and young women who chose either postplacental IUDs or postpartum contraceptive implants prior to hospital discharge. We used chart review and phone interviews to assess device discontinuation (by request or expulsion) and pregnancy within 12 months. Of the 244 13-22 year-old participants, 82 chose IUDs (74 levonorgestrel IUDs and 8 copper IUDs), and 162 chose implants. Both groups had participant-requested discontinuation rates of 14% (9/67 IUD; 19/135 implant) within 1 year. Participants choosing IUDs had a 25% (17/67) expulsion rate. Median time to expulsion was 4.1 weeks (range: 0.4-29.3 weeks, 16/17 within 12 weeks), and participants recognized 15/17 expulsions. IUD initiators had significantly higher pregnancy rates by 12 months (7.6% vs. 1.5%, p=0.04). Most pregnancies occurred when women discontinued their initial device and did not start alternative contraception. Participant-requested discontinuation was similar in both groups. Differences in overall device discontinuation rates were due to IUD expulsions. Pregnancy rates by 12 months postpartum were lower than previously reported in this age group in both implant initiators and IUD initiators. Young mothers who choose postplacental IUDs or postpartum contraceptive implants are unlikely to request removal within the first year. Clinicians should counsel postplacental IUD users that early expulsion is common (25%) and may be unrecognized (11% of expulsions). Patients should have a plan for contraceptive management should expulsion occur. Copyright © 2016 Elsevier Inc. All rights reserved.
Full Text Available Christopher U Iklaki, Anthony U Agbakwuru, Atim E Udo, Sylvester E Abeshi Department of Obstetrics and Gynaecology, University of Calabar, Calabar, Nigeria Background: The intrauterine devices (IUDs are widely used contraceptive methods all over the world today. They are effective and recommended for use up to 10 years. They are not without side effects, which often prompt the users to request for removal. Objective: To determine the utilization rate of copper T intrauterine contraceptive device (IUCD, side effects, and request for removal at the University of Calabar Teaching Hospital, Calabar. Methods: The data on usage of the various forms of temporary contraception provided by the Family Planning Clinic of this center from January 1, 2006 to December 31, 2010 were collated. The records of usage of IUCD during same period were carefully studied. Results: During this period, a total of 10,880 users were provided with various forms of contraceptives. Copper T IUD was the commonest form of contraception used at the University of Calabar Teaching Hospital Family Planning Unit over the period under review (2006–2010 with a rate of 4,069 (37.40%. There was a yearly higher request for IUCD over other forms of contraceptives over the period. Of a total of 4,069 users of the copper T IUD method over the period, 1,410 (34.65% belonged to the age group of 25–29 years. Eleven (4.61% of the users requested for its removal due to abnormal vaginal bleeding, while five (2.08% removed theirs due to abnormal vaginal discharge. The major reason for removal was the desire for pregnancy that accounted for 165 (70.26%, while one (0.51% was removed due to dysmenorrhea. Conclusion: The copper T380A was very effective, safe with fewer side effects, and easily available in this study. The request for removal is also low in our environment. Keywords: copper T380A, contraception, request for removal

Full Text Available Objective. To assess awareness of and interest in intrauterine contraceptive device (IUCD use among HIV-positive women in Cape Town, South Africa. Design. Cross-sectional survey. Methods. HIV-positive women aged 18 through 45 years presenting for care at a primary health care clinic in Cape Town, South Africa participated in this study. Consented participants completed a staff-administered questionnaire in a private setting. Descriptive statistics were generated. Comparisons between demographic and reproductive health-related variables and IUCD awareness and interest were performed with multiple logistic regression. Analyses for IUCD interest excluded women with prior surgical sterilization. Results. Of 277 HIV-positive women, 37% were aware of the IUCD; awareness was independently associated with greater age (adjusted odds ratio (AOR = 1.15, 95%; confidence interval (CI: 1.10–1.20 and not switching contraceptive methods in the last year (AOR = 2.45, 95% CI: 1.03–5.83. Following an IUCD information session, 86% of women (=206/240 were interested in IUCD use. IUCD interest was inversely associated with age (AOR = 0.91, 95% CI: 0.86–0.97 and marginally positively associated with current menstrual bleeding pattern complaints (AOR = 2.14, 95% CI: 0.98–4.68. Conclusions. Despite low levels of method awareness, HIV-positive women in this setting are frequently interested in IUCD use, indicating need for programming to expand method access.

A 49-year-old female from China was referred to our hospital after endocervical polypectomy. Twenty years before admission, after the birth of her first child, an intrauterine device (IUD) had been inserted due to the one-child policy in China. She had noticed abnormal vaginal bleeding with a foul smell 3 years before admission. Then the IUD was removed and a polyp was found at the IUD contact site. Two months before admission, endocervical polypectomy was performed. Lymphoma was suspected by histological examination and she was referred to our hospital. Further examination confirmed the diagnosis of primary uterine diffuse large B-cell lymphoma (DLBCL). Subsequently, a combination of three cycles of R-CHOP regimen and involved-field radiation therapy was performed, followed by maintenance therapy with five cycles of rituximab. She has remained in complete remission for over 1 year. This case suggests that chronic inflammation induced by prolonged IUD insertion may contribute to the development of primary uterine lymphoma. To the best of our knowledge, this is the first reported case of DLBCL associated with prolonged IUD insertion.
Full Text Available Background: Promoting family planning practices aid considerably in attaining Millennium Development Goals by various mechanisms. Despite concerted health system efforts, adoption of especially reversible contraceptive methods such as intrauterine devices (IUDs has remained negatively skewed in India, which is the pioneer country to implement Family Planning programme way back in 1952. Although few studies in India have looked into the reasons for its nonacceptance, literature from Odisha was scant and hence the study was undertaken. Methodology: A cross-sectional study using qualitative methods was done in the Mahanga Tehsil of Cuttack district. In-depth interviews were conducted with women of reproductive age (WRA and focused group discussions (FGDs among health workers and health professionals were held separately. Data analysis was done using thematic framework approach supported by Atlas Ti software. Results: There were 31 in-depth interviews with WRA, two FGDs with health workers, and one FGD with health professionals. Availability of IUD services was low and wherever available, being located far away affected its physical accessibility. Most women were reluctant to ask health workers about services owing to their shyness while many women felt using IUDs breached their autonomy and privacy. The existence of fear and misconceptions regarding its use rooting from lack of knowledge and poor service quality also impeded its adoption by women. Conclusion: There is a pressing need to enhance the demand of IUDs by dispelling the myths among women through effective information, education, and communication and also to improve the availability of IUDs.

Fear of pain during intrauterine device (IUD) insertion can be a barrier to widespread use of this safe and highly effective contraceptive method. Our objective was to determine the effectiveness of topical 10% lidocaine spray for pain control during IUD insertion. A total of 200 subjects with the request for IUD insertion were included in the study. The patients were randomly divided into two groups: lidocaine spray (n=100) and placebo (n=100). The pain experienced during the procedure was measured immediately after insertion by a standard Visual Analogue Scale (VAS) administered by a separate researcher with maintenance of allocation concealment. The mean pain score during the procedure was 1.01±1.20 in the lidocaine spray group and 3.23±1.60 in the placebo spray group (pLidocaine spray treatment significantly lowered the overall procedural pain score compared with placebo. Significant pain reduction during IUD insertion can be achieved by using 10% lidocaine spray alone. Lidocaine spray can be accepted as a non-invasive, easy to apply and more comfortable local anaesthetic method for IUD insertion. NCT02020551. Published by the BMJ Publishing Group Limited.

Intrauterine device (IUD) use has been shown to reduce the risk of endometrial cancer, but little is known about its association with cervical cancer risk. We assessed whether IUD use affects cervical human papillomavirus (HPV) infection and the risk of developing cervical cancer. We did a pooled analysis of individual data from two large studies by the International Agency for Research on Cancer and Institut Català d'Oncologia research programme on HPV and cervical cancer; one study included data from ten case-control studies of cervical cancer done in eight countries, and the other included data from 16 HPV prevalence surveys of women from the general population in 14 countries. 2205 women with cervical cancer and 2214 matched control women without cervical cancer were included from the case-control studies, and 15,272 healthy women from the HPV surveys. Information on IUD use was obtained by personal interview. HPV DNA was tested by PCR-based assays. Odds ratios and 95% CIs were estimated using multivariate unconditional logistic regression for the associations between IUD use, cervical HPV DNA, and cervical cancer. After adjusting for relevant covariates, including cervical HPV DNA and number of previous Papanicolaou smears, a strong inverse association was found between ever use of IUDs and cervical cancer (odds ratio 0·55, 95% CI 0·42-0·70; pCientifico e Tecnologico, Brazil; and Department of Reproductive Health & Research, WHO.

To evaluate endometrial and subendometrial microvascularization, using three-dimensional (3D) power Doppler ultrasound, in women with intrauterine device (IUD)-induced menorrhagia; and whether those potential findings could predict the risk of bleeding before IUD insertion. Prospective clinical trial. University teaching hospital. One hundred twenty women, who requested the insertion of a copper IUD for contraception. Endometrial thickness and volume, uterine artery pulsatility index and resistance index, and endometrial and subendometrial 3D power Doppler vascularization index, flow index, and vascularization flow index were measured twice: immediately before and 3 months after IUD insertion. Doppler indices before and after IUD insertion. Before IUD insertion, no significant difference was detected in the clinical characteristics, endometrial thickness and volume, and Doppler indices between women who had IUD-induced menorrhagia (n = 47) and those without menorrhagia (n = 73). However, after IUD insertion, there was a significant increase in the endometrial and subendometrial vascularization index, flow index, and vascularization flow index in women with menorrhagia, whereas other parameters remained not significantly different between the two groups. Endometrial and subendometrial microvascularization increases in women with IUD-induced menorrhagia; however, this finding has no predictive value before IUD insertion.

Full Text Available BACKGROUND In view of high rate of teenage marriages, unintended pregnancies and low rate of birth spacing in this region, there is a need for reliable, effective, long-term contraception such as Intrauterine Contraceptive Device (IUCD in postpartum women. The present study was planned to evaluate the safety and efficacy of postplacental IUCD insertion in women delivering vaginally or by caesarean section in a tertiary care centre facility in East Godavari District of Coastal Andhra Pradesh. MATERIALS AND METHODS The women recruited had Cu-T 380A insertion immediately after delivery of placenta in vaginal or caesarean delivery. The women were followed up at 6 weeks and 6 months after delivery. RESULTS A total of 123 women were included in the study. 93.4% women reported for 1 st follow up at 6 weeks and 73% women reported for 2nd follow up at the end of 6 months. The cumulative expulsion rate at the end of 6 months was 8.67%. Cases required removals of Cu-T in view of menorrhagia were 4%. There were no cases of misplaced IUCD, PID, perforation of uterus, pain abdomen. However, 4% of women got IUCD removed due to domestic reasons. CONCLUSION Although, the expulsion rate for immediate postpartum insertion was higher than for interval insertion, the benefits of providing highly-effective contraception immediately after delivery outweigh this disadvantage particularly in a rural area where women have limited access to medical care.
Full Text Available Background. Immediate postpartum intrauterine contraceptive device (IPPIUCD is a lucrative postpartum family planning method which provides effective reversible contraception to women in the delivery setting. Our aim was to study the clinical outcomes of IPPIUCD insertions and compare them as a factor of route of insertion (vaginal versus caesarean. Methods. This is a retrospective analytical study done in a tertiary care teaching institute. A Cohort of 593 vaginal and caesarean deliveries with IPPIUCD insertions, over a two-year period, was studied and compared for follow-up results. Outcome measures were safety (perforation, irregular bleeding, unusual vaginal discharge, and infection, efficacy (pregnancy, expulsions, and discontinuations, and incidence of undescended IUCD strings. Descriptives were calculated for various outcomes and chi square tests were used for comparison in between categorical variables. Results. Overall complication rates were low. No case of perforation or pregnancy was reported. Spontaneous expulsions were present in 5.3% cases and were significantly higher in vaginal insertions (p=0.042. The incidence of undescended strings was high (38%, with highly significant difference between both groups (p=0.000. Conclusion. IPPIUCD is a strong weapon in the family planning armoury and should be encouraged in both vaginal and caesarean deliveries. Early follow-up should be encouraged to detect expulsions and tackle common problems.

To determine medical eligibility for contraceptive use, contraceptive preference, and acceptance of a copper intrauterine device (IUD) among a cohort of HIV-infected women receiving antiretroviral therapy (ART). All HIV-infected women who received ART and sought contraceptive services at the Lighthouse clinic, an integrated HIV/ART clinic in Lilongwe, Malawi, between August and December 2010 were invited to participate in a structured interview. Eligibility and preference for the following contraceptive methods were assessed: combined hormonal contraceptives, progestogen-only pills, copper IUD, injectable depot medroxyprogesterone acetate (DMPA), and contraceptive implants. The final sample included 281 women; five were pregnant. The remaining 276 women were eligible for at least three contraceptive methods, with 242 (87.7%) eligible for all five methods evaluated. After counseling, 163 (58.0%) selected DMPA and 98 (34.9%) selected an IUD as their preferred contraceptive method. Regardless of their method of choice, 222 (79.0%) women agreed to have an IUD placed on the same day. Most methods of contraception are safe for use by HIV-infected women. Approximately 80% of the women were willing to receive an IUD. Efforts must be made to increase education about, and access to, long-acting reversible methods that may be acceptable and appropriate contraceptive options for HIV-infected women.

Full Text Available Abstract Introduction Intrauterine contraceptive devices may at times perforate and migrate to adjacent organs. Such uterine perforation usually passes unnoticed with development of potentially serious complications. Case presentation A 25-year-old woman of North Indian origin presented with an acute tender lump in the right iliac fossa. The lump was initially thought to be an appendicular lump and treated conservatively. Resolution of the lump was incomplete. On exploratory laparotomy, a hard suspicious mass was found in the anterior abdominal wall of the right iliac fossa. Wide excision and bisection of the mass revealed a copper-T embedded inside. Examination of the uterus did not show any evidence of perforation. The next day, the patient gave a history of past copper-T Intrauterine contraceptive device insertion. Conclusions Copper-T insertion is one of the simplest contraceptive methods but its neglect with inadequate follow-up may lead to uterine perforation and extra-uterine migration. Regular self-examination for the "threads" supplemented with abdominal X-ray and/or ultrasound in the follow-up may detect copper-T migration early. To the best of our knowledge, this is the first report of intrauterine contraceptive device migration to the anterior abdominal wall of the right iliac fossa.

Materials and methods: This was an insertion-related, prospective, postmarketing study in 309 women. Following insertion, women were followed up at 4–6 weeks, 6 months, and yearly thereafter. The position of the visualized anchor in the fundus of the uterus was evaluated using ultrasound by measuring its distance from the serosal surface of the uterus (SA-distance. Results: A total of 309 parous (n=115 and nulliparous (n=194 women were fitted with the frameless GyneFix 200 or the GyneFix 330 intrauterine device for contraception. The mean SA-distance in 306 parous and nulliparous women was 6.0 mm (range 2.0–24.0 mm at insertion in the parous group and 5.4 mm (range 1.3–11.0 mm in the nulliparous group.

This study was performed to study the prevalence and potential pathogenicity of E. gingivalis in the genital tracts of intrauterine contraceptive device (IUD) users. A prospective study conducted at the Obstetrics and Gynecology Department and Fertility Care Unit, Mansoura University Hospital, Egypt. The study was carried out on 87 IUD users and 87 nonusers. The copper T 380A IUD was removed from each woman and washed with phosphate-buffered saline (PBS) pH 7.4; the IUD wash was centrifuged. The sediment was resuspended in 2 ml PBS and divided into two portions. One portion was used for preparation of direct and iron hematoxylin-stained smears. Direct smears and stained smears were examined for detailed morphology. The second portion of the sediment was used for DNA extraction and subsequent PCR amplification targeting the small subunit ribosomal RNA of E. gingivalis. The parasite was found in 12.64% of IUD users and in 6.9% of non users (p>.3). It was found that 90.9% of those harboring E. gingivalis in their genital tract had the parasite in their oral cavity. The percentage of genital infection in IUD users increased with low level of education, rural areas, insertion in primary health-care center and among those not washing hands before checking the strings. In the infected cases, vaginal discharge was more common (81.8%) than in noninfected cases (32.9%), such difference was statistically significant (pvaginal discharge is more common than backache and menorrhagia in the infected cases. Higher incidence of E. gingivalis infection in IUD users is related to oral cavity infection, residence, the facility where they inserted their IUD and washing hands attitude before checking the strings. We recommend treatment of gingival infection, proper counseling and medical education on oral and genital tract hygiene for IUD users. Copyright © 2012 Elsevier Inc. All rights reserved.
Full Text Available Background: To investigate the effect of using intrauterine devices (IUDs during the fertile window on women′s reproductive system health. Materials and Methods: 2,744 postmenopausal women in the Minhang District, Shanghai, China were enrolled. In the IUDs group there were 2,253 women; in the tubal ligation group there were 202 women and there were 289 women in the control group. We selected subjects according to the cases number in different hospital by using step sampling, and, in addition, collected the sociological data and information of the previously used contraceptives by the subjects, which included whether the contraceptives were used appropriately and the effect they had. Kolmogorov-Smirnov test, Levene′s test, and logistic regression analysis were used to analyze the data. Results: The prevalence rate of benign reproductive system conditions was significantly different among them (P < 0.05. Further comparison revealed, the rate in Group 1 was significantly lower than that in Group 2 and Group 3 (P < 0.05, respectively. Results of logistic regression analysis show that the risk factors for development of such conditions lie in the women′s pregnancy history [odds ratio (OR = 3.85], reproductive history (OR = 0.5, the use of IUD in fertile window (OR = 0.4, tubal ligation (OR = 1.74, birth control time (OR = 0.9, contraceptive failure history (OR = 1.7, and history of family planning procedures (OR = 1.73. Conclusion: IUDs, maybe, can effectively reduce the risk of getting benign reproductive conditions in postmenopausal females.

Women with depressive or bipolar disorders are at an increased risk for unintended pregnancy. To examine the safety of hormonal contraception among women with depressive and bipolar disorders. We searched for articles published through January 2016 on the safety of using any hormonal contraceptive method among women with depressive or bipolar disorders, including those who had been diagnosed clinically or scored above threshold levels on a validated screening instrument. Outcomes included changes in symptoms, hospitalization, suicide and modifications in medication regimens such as increase or decrease in dosage or changes in type of drug. Of 2376 articles, 6 met the inclusion criteria. Of three studies that examined women clinically diagnosed with depressive or bipolar disorder, one found that oral contraceptives (OCs) did not significantly change mood across the menstrual cycle among women with bipolar disorder, whereas mood did significantly change across the menstrual cycle among women not using OCs; one found no significant differences in the frequency of psychiatric hospitalizations among women with bipolar disorder who used depot medroxyprogesterone acetate (DMPA), intrauterine devices (IUDs) or sterilization; and one found no increase in depression scale scores among women with depression using and not using OCs, for both those treated with fluoxetine and those receiving placebo. Of three studies that examined women who met a threshold for depression on a screening instrument, one found that adolescent girls using combined OCs (COCs) had significantly improved depression scores after 3 months compared with placebo, one found that OC users had similar odds of no longer being depressed at follow-up compared with nonusers, and one found that COC users were less frequently classified as depressed over 11 months than IUD users. Limited evidence from six studies found that OC, levonorgestrel-releasing IUD and DMPA use among women with depressive or bipolar

The aim of this study was to analyze all available evidence regarding the use of intrauterine morcellator (IUM), for treatment of the most prevalent intrauterine benign lesions, compared to both traditional resectoscopy and conventional outpatient operative hysteroscopy in terms of safety, efficacy, contraindications, perioperative complications, operating time, and estimated learning curve. We reported data regarding a total of 1185 patients. Concerning polypectomy and myomectomy procedures, IUM systems demonstrated a better outcome in terms of operative time and fluid deficit compared to standard surgical procedures. Complication rates in the inpatient setting were as follows: 0.02% for IUM using Truclear 8.0 (Smith & Nephew Endoscopy, Andover, Massachusetts) and 0.4% for resectoscopic hysteroscopy. No complications were described using Versapoint devices. Office polipectomy reported a total complication rate of 10.1% using Versapoint device (Ethicon Women's Health and Urology, Somerville, New Jersey) and 1.6% using Truclear 5.0 (Smith & Nephew Endoscopy). The reported recurrence rate after polypectomy was 9.8% using Versapoint device and 2.6% using Truclear 8.0. Finally, the reported intraoperative and postoperative complication rate of IUM related to removal of placental remnants using Truclear 8.0 and MyoSure (Hologic, Marlborough, Massachusetts) was 12.3%. The available evidence allows us to consider IUM devices as a safe, effective, and cost-effective tool for the removal of intrauterine lesions such as polyps, myomas (type 0 and type 1), and placental remnants. Evidence regarding Truclear 5.0 suggests that it may represent the best choice for office hysteroscopy. Further studies are needed to confirm the available evidence and to validate the long-term safety of IUM in procedures for which current data are not exhaustive (placental remnants removal). © The Author(s) 2015.

This document provides clinicians with up-to-date information on IUDs in regard to safety, acceptance, effectiveness, insertion technics, insertion timing, continuing care, complications and their management, contraindications, subsequent fertility, and current research to improve IUDs. IUD popularity is increasing in the U. S. 6.4% of all eligible currently married women use IUDs in the U. S. IUD continuation rates are approximately 75% during the 1st year. The pregnancy rate is 4/100 women years of use, and the expulsion rate is 4-18/100 users. IUDs are associated with a lower mortality rate than most other methods and the rate of complications requiring hospitalization is 0.3-1.0/100 women years of use. There is no evidence that IUDs increase the risk of gynecologic malignancy but IUDs are associated with an increased risk of pelvic infection among certain groups. The IUD must be placed high in the uterine fundus but care must be taken to avoid uterine perforation. The advantages and disadvantages of using different types of IUDs were discussed. Clinical conditions which must be taken into account in prescribing and selecting an appropriate IUD were also described. IUDs were also described. IUDs are ideally inserted during menstruation and some pain and bleeding frequently accompanies insertion. After insertion the patient should return for a check-up within 3 months and then annually. Guidelines for the management of complications such as expulsion, excessive bleeding and cramping, perforation, pregnancy, and pelvic infections were provided. After IUD removal there is a risk that fertility return will be delayed and among women who developed infections while using an IUD there is risk of sterility. Current research efforts are directed primarily at developing IUDs which produce fewer side effects and which have longer life spans.

In Ethiopia, modern contraceptive prevalence among currently married women nearly tripled over the last decade, but the method mix remains skewed toward short-acting methods. Since 2011, the Integrated Family Health Program (IFHP+), jointly implemented by Pathfinder International and John Snow Inc., has supported the Federal Ministry of Health to introduce intrauterine devices (IUDs) in more than 800 health centers across 4 regions to improve access to a wider range of methods. Between March and August 2014, Pathfinder conducted a mixed-methods study in 40 purposively selected health centers to assess shifts in the contraceptive method mix following introduction of IUDs using data from family planning registers; determine the characteristics of IUD users through a cross-sectional survey of 2,943 family planning clients who accepted the IUD; explore reasons for method discontinuation among 165 clients seeking IUD removal services; and identify facilitators and barriers to IUD use through focus group discussions (N = 115 clients) and key informant interviews (N = 36 providers, facility heads, and health office heads). Introduction of IUDs into the 40 health centers participating in the study was correlated with a statistically significant increase in the contribution of all long-acting reversible contraceptives (LARCs)-both IUDs and implants-to the method mix, from 6.9% in 2011 to 20.5% in 2014 (Pmethod was acceptable to a broad cross-section of women. Of the 2,943 women who sought IUDs during the 6-month study period, 18.0% were new contraceptive users (i.e., those using a contraceptive method for the first time ever), 44.7% reported no educational attainment, 62.5% were from rural areas, and 59.3% were younger than 30 years old, with almost 3 in 10 (27.7%) under the age of 25. The most commonly cited reason for seeking IUD removal services was a desire to become pregnant (43% of women). Qualitative data indicated that while acceptability of the method is
The objective of our study was to document the efficacy and possible complications in women who were treated for menorrhagia with the simultaneous use of endometrial ablation and the levonorgestrel-releasing intrauterine device. Women were offered this combined treatment if they complained of menorrhagia and needed contraception. A structured questionnaire was mailed to 150 women who had undergone this combined treatment; 105 (70%) returned a completed questionnaire. The mean duration of follow-up was 25 months (range 6-54 months). Following treatment, 53 women (50.5%) described their periods as being lighter than normal and 49 (46%) had become amenorrhoeic. Overall, 101 (96%) stated that they were satisfied with the treatment. Of the women, 95 (90.5%) said that the treatment had been a \\'complete success\\'; eight (7.6%) \\'partly successful\\' and two women (1.9%) said the treatment had been a \\'failure\\'. One woman subsequently required a hysterectomy. This observational study supports the hypothesis that combined endometrial ablation and insertion of a levonorgestrel-releasing intrauterine device is an effective treatment for menorrhagia and has some advantages when compared with the individual use of these treatments.

To determine the effect of two levels of counselling on the provision of Intrauterine Contraceptive Device (IUCD) at six weeks post-partum of the post-placental intrauterine device. Embu Provincial General Hospital, Kenya. One hundred and thirty seven pregnant women at the gestation of 36 weeks to term, who attended Antenatal clinic and were followed until delivery and at six weeks post-partum. A randomised "open-label" clinical trial. One hundred and twenty seven study participants were enrolled and randomised to intensive (64 women) or routine FP counselling (63 women). Seventy eight per cent of women in the intensive FP counselled group and 66% in the routine FP counselled group accepted to have the post-placental IUCD inserted. There was no significant difference in uptake in the two-randomisation arms (p-value 0.232). Complications included expulsion (3.7%), allergic reaction (1.8%), pelvic infection (1.8%) and abdominal pain (1.8%).The post-placental IUCD is a favourable method with continuation rates (91%), client (88%) and reported partner (77%) satisfaction were notably high at six weeks. The most critical barrier to uptake was lack of trained medical personnel to insert the post-placental IUCD, which occurred in (60%) clients who had consented. The post-placental IUCD is an acceptable method among women irrespective of level of counselling. Intensive counselling did not significantly increase acceptance and uptake rates of post-placental IUCD insertion in comparison to routine counselling.

Design: A convenience sample of 89 women aged 15–50 years attending a sexual health clinic for same day intrauterine contraception insertion were given a questionnaire that they completed following the procedure. The women were asked to rate their expectation of pain prior to insertion and to rate the actual pain they experienced immediately after insertion, on a scale of 1–10, with 10 being severe pain. Information on the women's circumstances and their level of satisfaction with the procedure was also obtained. Results: Overall, the median actual pain experienced by women during insertion (4 was significantly lower than the expected pain median (6 (P<0.001. For those women who had not had a previous vaginal delivery, actual pain was significantly higher compared with women who had had a previous vaginal delivery (median [interquartile range]: 6 [3.5–7.5] and 3 [1–5], P<0.001, respectively, but there was no significant difference between expected and actual pain experiences. In women who had a previous vaginal delivery, actual pain was much lower than expected (P<0.001.

Difficulties with adequately processing intrauterine device (IUD) insertion instruments and supplies have led to use of potentially contaminated items, compromising the quality and safety of IUD insertion services in Bangladesh. A sterilization process for IUD insertion instruments and supplies by using a commercially available portable steam sterilizer was developed and validated. Racks provided with the sterilizer were used during sterilization of wrapped supplies (gloves and cotton balls). Metal compartments to hold insertion instruments were built to fit into the sterilizer. After sterilization, supplies were transported to rural service sites in plastic bags, whereas instruments remained in the sterilizer, which was transported in a carrying case. To validate the sterilizer, laboratory testing was conducted by using chemical and biologic indicators for steam sterilization and field testing in Bangladesh with chemical indicators. Results indicated that sterilization cycles were effective in achieving sterility of IUD insertion supplies and instruments at sterility assurance levels of 10(-5) and 10(-6), respectively. Use of this sterilizer for IUD insertion supplies and instruments will improve the quality of service delivery in the Bangladesh family-planning program and has application for use in many other low-resource settings.

This study investigated the acceptability of the levonorgestrel-releasing intrauterine device (LNG-IUS) as contraception among young, single women after termination of pregnancy. Twenty subjects, with a median age of 21 years, had LNG-IUS inserted immediately after suction termination of first-trimester pregnancy. The subjects were followed-up at 6 weeks, 3 months, 6 months and 12 months. Fifteen subjects (75%) had other pregnancies terminated in the past. There were no serious complications or pregnancies. The acceptability of the LNG-IUS was generally above 86% during each follow-up visit. A total of seven (35%) subjects were lost to follow-up at different periods of the study. Overall, four subjects (22%) had the LNG-IUS removed. Nine subjects were seen at the end of the 1-year study period and all continued with the LNG-IUS for contraception. Side effects were commonly observed and irregular vaginal bleeding was the most common. We conclude that the LNG-IUS may be an acceptable method among selective young, single, nulliparous clients after termination of pregnancy and could be offered as an option of contraception to them. However, the small sample size and the high lost-to-follow-up rate are the major limitations of this study.

To compare the findings of the case-control and cohort studies used to indict the Dalkon Shield (A.H. Robins Company, Inc., Richmond, VA) with the findings of the Dalkon Shield clinical trials. All published reports on the Dalkon Shield were identified through MEDLARS system (United States National Library of Medicine) searches and by cross checking all references in these reports. The same approach was used to identify all case-control and cohort studies of the purported relationship between intrauterine devices (IUDs) and pelvic inflammatory disease (PID). Only studies of interval patients that included 50 or more women and 6 or more months of follow up that computed standard IUD event rates (rates of pregnancy and expulsion and removal for pain and bleeding) were selected for this study. All case-control and cohort studies identified were included except two case-control studies that included women with sterile chronic salpingitis. The 16 case-control and 2 cohort studies found or suggested that the Dalkon Shield increased the risk of PID. The 71 clinical trials of the Dalkon Shield show that when this device is inserted by an experienced clinician it is a safe and effective contraceptive method, comparable with other IUDs used at the time. There was no evidence of an increased risk of PID found in these clinical trials. This study offers convincing evidence that the indictment of the Dalkon Shield was a mistake. Additionally, this study shows that physician skill and experience is far more important to successful IUD insertion than previously recognized, a finding with considerable implications for IUD study designs and for marketing strategies.

Emergency contraception must be followed by the use of an effective method of contraception in order to reduce future risk of unintended pregnancies. Provision of long-acting reversible contraception (LARC) is highly effective in this regard. The aim of our study was to compare use of an effective method of contraception 6 months following insertion of a copper intrauterine device (Cu-IUD) or intake of ulipristal acetate (UPA) for emergency contraception (EC). Women (n = 79) presenting with need for EC at an outpatient midwifery clinic chose either Cu-IUD or UPA according to preference. Follow up was 3 and 6 months later through telephone interviews. Primary outcome was use of an effective contraceptive method at the 6-month follow up. Secondary outcomes included use of an effective contraceptive method at 3 months follow up and acceptability of Cu-IUD. A total of 30/36 (83.3%) women who opted for Cu-IUD for EC used an effective contraceptive method 6 months after their first visit compared with 18/31 (58.1%) women who opted for UPA (p = 0.03). In the Cu-IUD group 28/36 (77.8%) were still using Cu-IUD at 6 months and 31/36 (86%) stated that they would recommend the Cu-IUD to others as an EC method. Significantly more women who chose Cu-IUD for EC used an effective method for contraception at the 6-month follow up. The results of this study support increased use of Cu-IUDs for EC. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

The association of contraceptive methods, including oral contraceptives (OC), intrauterine devices (IUD) and tubal sterilization (TS), with overall and site-specific cancer were prospectively investigated in a cohort of 66,661 Chinese women in Shanghai; 76.7% of whom used contraception. During a median follow up time of 7.5 years, 2,250 women were diagnosed with cancer. Ever-use of any contraceptive method was not associated with overall cancer risk [adjusted hazard ratio (HRadj)=1.02, 95% CI 0.92–1.12]. Use of any contraceptive method was associated with increased risk of rectal cancer (HRadj=1.68, 95% CI 1.08–2.62) and reduced risk of thyroid cancer (HRadj=0.63, 95% CI 0.38–1.04). Risk of gallbladder cancer increased with ever use of OC (HRadj=2.38, 95% CI 1.26–4.49). IUD use was associated with a possible reduced risk of thyroid cancer (HRadj=0.64, 95% CI 0.38–1.07). Longer duration of IUD use decreased risk for breast, thyroid, and lung cancers. Ever having a TS was associated with increased uterine body cancer (HRadj=2.50, 95% CI 1.47–4.25) and decreased risk of stomach cancer (HRadj =0.59, 95% CI 0.39–0.91). We did not find any contraceptive method to be related to the risk of ovarian cancer but the analyses were based on few events. Although chance findings are a likely explanation for some of the associations found in our study, these findings may suggest that various contraceptive methods or reproductive patterns may play a role in the etiology of cancer.

To assess the prevalence of anemia and VulvoVaginal Candidiasis (VVC) in women before and 3 months after copper Intra Uterine Device (IUD) insertion. Longitudinal prospective study was performed with 101 women aged 15-45 year who wanted to use the IUD at six health centers in Tehran, Iran from November 2011 to August 2012. The pattern of bleeding, Hemoglobin and Hematocirt levels, and Candida colony count/cultures in the women were assessed before and after 3 months of IUD insertion. Data analysis was performed by descriptive and analytical statistics using the SPSS software for Windows. At the end of 3 months, a significant increase in menstrual blood loss and a significant decrease of Hb and HCT (P=0.047 and 0.001, respectively) were reported. Moreover, no difference in the prevalence of anemia before and after IUD insertion was observed. The mean±SD Candida colony counts significantly increased (P=0.001), but positive Candida cultures were not significantly different before and 3 months after IUD insertion. Also, no clinical VVC was reported 3 months after IUD insertion. While BMI≥29 had a positive relationship with Candida colony counts, the results remained unchanged after adjusting for potential risk factors. Despite an increase in bleeding and Candida colony counts in copper IUD users in this study, clinical VVC or anemia cases were not increased, which indicates relative safety of this contraception method. The study findings can be helpful to healthcare professionals and midwives to counsel women who want to start using IUD and also current users who are contemplating IUD removal due to its complications.

This study was conducted to investigate the antifertility effectiveness of a novel copper-containing composite used in intrauterine contraceptive devices (IUDs) that contain cupric chloride/silicon dioxide/poly(vinyl alcohol) (CuCl₂/SiO₂/PVA) and the releasing behavior of cupric ions in the composite into the serum and uterine fluid in rats. Two hundred and forty sexually mature female Sprague-Dawley rats were randomly divided into six groups: sham-operated control group (n=20), bulk copper group (Cu group, n=40), SiO₂/PVA group (n=40), CuCl₂/SiO₂/PVA groups I (n=40, copper ion was released from IUD at a rate of 5-10 mcg/220 mm² per day) and II (n=40, copper ion was released from IUD at a rate of 10-20 mcg/220 mm² per day), and normal control group (n=20). IUD was inserted into the uterus of rats after acclimatization of 1 week. At different time points after implantation of the IUDs, cupric ion concentrations were measured in the serum and local uterine fluid in each group by flame atomic absorption, respectively. After 30 days of insertion, half of the rats in each group were mated with fertile male rats, and the antifertility rates were observed at 14 days of pregnancy. After the IUDs were removed, the remaining rats in each group were mated again to determine their fertility. Antifertility rates in the Cu group and CuCl₂/SiO₂/PVA groups I and II were 100%, and each of these rates was significantly higher than that in the other groups (p.05). No significant change in time dependence was found for the serum cupric ion concentrations in each group (p>.05), while the local uterine fluid cupric ion concentrations in the other groups were significantly lower than those in the Cu group (pcontraceptive devices (CuCl₂/SiO₂/PVA composite IUD) had a low pregnancy rate and high contraceptive efficacy without a burst release of cupric ions in the initial days of application.

Is there any difference in the clinical performance of the 3-year one-rod etonogestrel (ENG)- and the 5-year two-rod levonorgestrel (LNG)-releasing contraceptive implants during 3 years of insertion, and between implant and intrauterine device (IUD) contraception, in particular complaints possibly related to hormonal contraceptives? The cumulative contraceptive effectiveness after 3 years and method continuation through 2.5 years were not significantly different between ENG and LNG implants, but both outcomes were significantly worse in the non-randomized age-matched group of IUD users than in the combined implant group. ENG- and LNG-releasing implants are safe and highly efficacious contraceptives with pregnancy rates reported to be 0.0-0.5 per 100 women-years (W-Y). No head-to-head comparative study of the two implants has been undertaken, and little information is available on comparisons of complaints of side effects of implant and copper IUD users. This was an open parallel group RCT with 1:1 allocation ratio of the ENG and the LNG implants with non-randomized control group of women choosing TCu380A IUD to address lack of reliable data on common side effects typically attributed to the use of progestogen-only contraceptives. After device(s) placement, follow-ups were at 2 weeks, 3 and 6 months, and semi-annually thereafter for 3 years or until pregnancy, removal or expulsion of the implant/IUD occurred. The study took place in family planning clinics in Brazil, Chile, Dominican Republic, Hungary, Thailand, Turkey and Zimbabwe. Women seeking long-term contraception were enlisted after an eligibility check and informed consent, and 2982 women were enrolled: 1003, 1005 and 974 in the ENG-implant, LNG-implant and IUD groups, respectively; 995, 997 and 971, respectively, were included in the per protocol analysis reported here. ENG and LNG implants each had the same 3-year cumulative pregnancy rate of 0.4 per 100 W-Y [95% confidence interval (CI) 0.1-1.4]. A weight

Full Text Available It is estimated that the true prevalence of intrauterine growth restriction is 3-10% of all pregnancies, making this fetal condition one of the most frequent obstetric problems, together with premature labor and premature rupture of membranes. The article stresses the importance of early diagnosis because of the associated risks.

A 51 year old woman presented for removal of her expired levonorgestrel intrauterine device (IUD). The IUD arms appeared absent upon IUD removal. Further examination of the device revealed that the arms were concealed inside the hormonal cylinder. Recognizing abnormal presentations of the levonorgestrel IUD upon removal can avoid unnecessary procedures. Copyright © 2014 Elsevier Inc. All rights reserved.
In March 2015, the U.S. Food and Drug Administration approved Liletta (Actavis, Dublin, Ireland), a new intrauterine device for contraception. The Centers for Disease Control and Prevention recommend use of long-acting reversible contraception (LARC) as first-line pregnancy prevention. LARC efficacy rates are similar to those of sterilization, with the possibility for quick return of fertility upon removal of the device. Despite benefits and recommendations for this form of contraception, access and high cost remain barriers to use. Liletta is the first lower-cost option for intrauterine contraception. Available to qualified clinics and health centers at a reduced rate, this device may increase availability and decrease the overall cost to women who desire intrauterine contraception. © 2016 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.
Comparing the effectiveness of copper intrauterine devices available in Canada. Is FlexiT non-inferior to NovaT when inserted immediately after first-trimester abortion? Study protocol for a randomized controlled trial
Norman Wendy V
Full Text Available Abstract Background We describe the rationale and protocol for a randomized noninferiority controlled trial (RCT to determine if the Flexi-T380(+ copper intrauterine contraceptive device (IUD is comparable in terms of effectiveness and expulsion rates to the most common Canadian IUD currently in use, NovaT-200, when placed immediately after a first-trimester abortion. Methods/Design Consenting women choosing to use an IUD after an abortion for a pregnancy of less than 12 weeks of gestation will be randomized to device-type groups to receive immediate post-abortion placement of either a Flexi-T380(+ IUD, a device for which no current evidence on expulsion or effectiveness rates is available, or the Nova-T200 IUD, the only other brand of copper IUD available in Canada at the time of study initiation. The primary outcome measure is IUD expulsion rate at 1 year. Secondary outcomes include: pregnancy rate, method continuation rate, complication rates (infection, perforation, and satisfaction with contraceptive method. A non-intervention group of consenting women choosing a range of other post-abortion contraception methods, including no contraception, will be included for comparison of secondary outcomes. Web-based contraception satisfaction questionnaires, clinical records, and government-linked health administrative databases will be used to assess primary and secondary outcomes. Discussion The RCT design, combined with access to clinical records at all provincial abortion clinics, and to information in provincial single-payer linked administrative health databases, birth registry, and hospital records, offers a unique opportunity to determine if a novel IUD has a comparable expulsion rate to that of the current standard IUD in Canada, in addition to the first opportunity to determine pregnancy rate and method satisfaction at 1 year post-abortion for women choosing a range of post-abortion contraceptive options. We highlight considerations of
Improving treatment for obese women with early stage cancer of the uterus: rationale and design of the levonorgestrel intrauterine device ± metformin ± weight loss in endometrial cancer (feMME) trial.

Endometrial adenocarcinoma (EC) is the most common gynaecologic cancer. Up to 90% of EC patients are obese which poses a health threat to patients post-treatment. Standard treatment for EC includes hysterectomy, although this has significant side effects for obese women at high risk of surgical complications and for women of childbearing age. This trial investigates the effectiveness of non-surgical or conservative treatment options for obese women with early stage EC. The primary aim is to determine the efficacy of: levonorgestrel intrauterine device (LNG-IUD); with or without metformin (an antidiabetic drug); and with or without a weight loss intervention to achieve a pathological complete response (pCR) in EC at six months from study treatment initiation. The secondary aim is to enhance understanding of the molecular processes and to predict a treatment response by investigating EC biomarkers. An open label, three-armed, randomised, phase-II, multi-centre trial of LNG-IUD ± metformin ± weight loss intervention. 165 participants from 28 centres are randomly assigned in a 3:3:5 ratio to the treatment arms. Clinical, quality of life and health behavioural data will be collected at baseline, six weeks, three and six months. EC biomarkers will be assessed at baseline, three and six months. There is limited prospective evidence for conservative treatment for EC. Trial results could benefit patients and reduce health system costs through a reduction in hospitalisations and through lower incidence of adverse events currently observed with standard treatment.

There have been conflicting reports of altered vaginal microbiota and infection susceptibility associated with contraception use. The objectives of this study were to determine if intrauterine contraception altered the vaginal microbiota and to compare the effects of a copper intrauterine device (Cu-IUD) and a levonorgestrel intrauterine system (LNG-IUS) on the vaginal microbiota. DNA was isolated from the vaginal swab samples of 76 women using Cu-IUD (n=36) or LNG-IUS (n=40) collected prior to insertion of intrauterine contraception (baseline) and at 6 months. A third swab from approximately 12 months following insertion was available for 69 (Cu-IUD, n=33; LNG-IUS, n=36) of these women. The V4 region of the bacterial 16S rRNA-encoding gene was amplified from the vaginal swab DNA and sequenced. The 16S rRNA gene sequences were processed and analyzed using the software package mothur to compare the structure and dynamics of the vaginal bacterial communities. The vaginal microbiota from individuals in this study clustered into 3 major vaginal bacterial community types: one dominated by Lactobacillus iners, one dominated by Lactobacillus crispatus and one community type that was not dominated by a single Lactobacillus species. Changes in the vaginal bacterial community composition were not associated with the use of Cu-IUD or LNG-IUS. Additionally, we did not observe a clear difference in vaginal microbiota stability with Cu-IUD versus LNG-IUS use. Although the vaginal microbiota can be highly dynamic, alterations in the community associated with the use of intrauterine contraception (Cu-IUD or LNG-IUS) were not detected over 12 months. We found no evidence that intrauterine contraception (Cu-IUD or LNG-IUS) altered the vaginal microbiota composition. Therefore, the use of intrauterine contraception is unlikely to shift the composition of the vaginal microbiota such that infection susceptibility is altered. Copyright © 2017 Elsevier Inc.

Animal experiments have suggested that the intrauterine environment causes secondary injury to the congenitally dysplastic spinal cord. This in turn suggests that early closure of the myelomeningocele sac might prevent secondary injury and therefore improve neurologic outcome. This study was designed to examine the technical feasibility of performing intrauterine myelomeningocele repair using a robot-assisted endoscopic system in an animal model. Six fetal sheep underwent creation and repair of a full-thickness skin lesion using the da Vinci system. With the device's advanced articulated instruments and three-dimensional optics, it was possible to endoscopically repair the induced skin defects. We conclude that, with the recent evolution in robotics and minimally invasive techniques, intrauterine endoscopic surgery has become a realistic goal that promises to reduce the associated risks of fetal surgery and extend the indications for its use.

Full Text Available Preterm birth remains the leading cause of perinatal mortality and morbidity. Evidence suggests that intrauterine infection plays an important role in the pathogenesis of preterm labor. This article reviews the clinical data supporting this theory and the cellular and biochemical mechanisms by which intrauterine infection may initiate uterine contractions. The clinical and laboratory methods of diagnosing clinical chorioamnionitis and asymptomatic bacterial invasion of the intraamniotic cavity are also reviewed. Finally, the management of clinical chorioamnionitis and asymptomatic microbial invasion of the amniotic fluid and the use of adjunctive antibiotic therapy in the treatment of preterm labor are presented.

Full Text Available Megan N Beatty, Paul D BlumenthalDepartment of Obstetrics and Gynecology, Stanford University, Stanford, CA, USAAbstract: The levonorgestrel-releasing intrauterine system (LNG-IUS is a safe, effective and acceptable form of contraception used by over 150 million women worldwide. It also has a variety of noncontraceptive benefits including treatment for menorrhagia, endometriosis, and endometrial hyperplasia. The LNG-IUS has also been used in combination with estrogen for hormone replacement therapy and as an alternative to hysterectomy. Overall, the system is very well tolerated and patient satisfaction is quite high when proper education regarding possible side effects is provided. However, despite all of the obvious benefits of the LNG-IUS, utilization rates remain quite low in the developed countries, especially in the United States. This is thought to be largely secondary to the persistent negative impressions from the Dalkon Shield intrauterine experience in the 1970s. This history continues to negatively influence the opinions of both patients and health care providers with regards to intrauterine devices. Providers should resolve to educate themselves and their patients on the current indications and uses for this device, as it, and intrauterine contraception in general, remains a largely underutilized approach to a variety of women’s health issues.Keywords: Mirena®, levonorgestrel-releasing, intrauterine system, intrauterine contraceptive device

We conducted a prospective health service evaluation to assess the feasibility and acceptability of routinely offering insertion of intrauterine contraception at cesarean section in a maternity setting in the UK. One month before scheduled cesarean section, women were sent information about postpartum contraception including the option of insertion of an intrauterine contraception at cesarean. Women choosing intrauterine contraception (copper intrauterine device or levonorgestrel intrauterine system) were followed up in person at six weeks, and telephone contact was made at three, six and 12 months postpartum. Our main outcome measures were uptake of intrauterine contraception and complications by six weeks. Secondary outcomes were continuation and satisfaction with intrauterine contraception at 12 months. 120/877 women opted to have intrauterine contraception (13.7%), of which 114 were fitted. By six weeks, there were seven expulsions (6.1%). The expulsion rate by one year was 8.8%. There were no cases of uterine perforations and one case of infection (0.8%). Follow-up rates were 82.5% at 12 months, and continuation rates with intrauterine contraception at 12 months were 84.8% of those contacted. At 12 months, 92.7% of respondents asked were either 'very' or 'fairly' happy with their intrauterine contraception. Routine provision of intrauterine contraception at elective cesarean for women in a public maternity service is feasible and acceptable to women. It is associated with good uptake and good continuation rates for the first year. This could be an important strategy to increase use of intrauterine contraception and prevent short inter-pregnancy intervals and unintended pregnancies. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

investigated oral estrogen therapy after hysteroscopy and found no difference in intrauterine adhesion. A meta-analysis showed no decrease in intrauterine adhesion with estrogen therapy after hysteroscopy. Data were lacking to perform metaanalyses on the use of intrauterine balloon, intrauterine device, and other adhesion prevention barriers in preventing intrauterine adhesion. There was a lack of definitive evidence to conclude that any treatment is effective in preventing posthysteroscopy uterine adhesion formation. The available literature has significant heterogeneity and a high risk of bias, making any definitive conclusions difficult. Published by Elsevier Inc.

Intrauterine growth restriction (IUGR) is a major and silent cause of various morbidity and mortality for the fetal and neonatal population. It is defined as a rate of fetal growth that is less than normal for the growth potential of that specific infant. The terms IUGR and small for gestational age (SGA) are often used interchangeably, although there exists subtle differences between the two. IUGR/SGA is an end result of various etiologies that includes maternal, placental and fetal factors and recently added genetic factors too, also contribute to IUGR. In this review article we will cover the antenatal aspect of IUGR and management with proven preventive intervention.

Preliminary evidence suggests that intrauterine myelomeningocele repair may benefit patients by reducing the both incidence of hydrocephalus and the severity of the Chiari malformation; however, this benefit remains unproved. Furthermore, the procedure entails substantial risks not associated with conventional therapy. A randomized controlled trial of intrauterine and conventional therapies is underway. This study should definitively establish the procedure related risks and benefits. Regardless of the outcome, it is clear that the risks of intrauterine intervention need to be reduced before myelomeningocele, or other congenital malformations, can be effectively treated prior to birth. To that end, studies are being conducted to assess the potential advantages of applying state-of-the-art endoscopic techniques to intrauterine therapy. If benefit can be proven and risks reduced, intrauterine myelomeningocele repair has the potential to become the preferred therapy for patients suffering from this debilitating disease.

Full Text Available Abstract Intrauterine growth retardation refers to a rate of growth of a fetus that is less than normal for the growth potential of a fetus (for that particular gestational age. As one of the leading causes of perinatal mortality and morbidity, intrauterine growth retardation has immense implications for the short term and long term growth of children. It is an important public health concern in the developing countries. Health statistics encompassing parameters for maternal and child health in the Indian subcontinent have shown improvement in the past few years but they are still far from perfect. Maternal health, education and empowerment bears a strong influence on perinatal outcomes including intrauterine growth retardation and should be the primary focus of any stratagem targeted at reducing the incidence of intrauterine growth retardation. A concerted liaison of various medical and social disciplines is imperative in this regard.

Immediate initiation of an intrauterine device (IUD) or intrauterine system (IUS) following termination of pregnancy (TOP) is associated with a significant reduction in the risk of another TOP. In spite of its high efficacy, uptake of intrauterine contraception in the UK is low. Myths and misconceptions about the method may contribute to the low uptake. Anonymous, self-administered questionnaire among women requesting a TOP in a hospital abortion service in Scotland, UK. Misconceptions about intrauterine contraception were extracted from an online social networking and micro-blogging service, and from existing research to develop a questionnaire containing 12 negative statements about intrauterine contraception. Respondents indicated their level of agreement with each statement. A total of 106/125 (85%) women requesting a TOP completed the questionnaire. The two commonest negative statements that respondents agreed with were that the IUD/IUS 'Is painful to have inserted' (n=36; 34%) and that 'It can move around inside your body' (n=25; 23.6%). The range of women who neither agreed nor disagreed with negative statements was 26.4-56.0%. Twenty-seven (25%) women indicated that the IUD/IUS was their planned method of post-TOP contraception. Although myths about intrauterine contraception persist among a small proportion of women requesting a TOP, lack of knowledge about the method is also evident. The consultation prior to TOP is an important opportunity to provide accurate and quality information to women about the IUD/IUS that may serve to increase uptake and prevent repeat abortions.

It has been reported that intrauterine myelomeningocele repair reduces the amount of hindbrain herniation normally seen in association with the Chiari type II malformation. It is not yet known, however, whether hindbrain herniation is prevented, or whether preexisting herniation is reversed. The following study was designed to elucidate this issue. A series of 9 patients underwent intraoperative ultrasound examinations immediately prior to intrauterine myelomeningocele repair. These same patients were then evaluated postnatally using ultrasound and/or MRI. The degree of hindbrain herniation before and after repair was compared using a grading system devised by the authors. Eight patients had clear evidence of moderate to severe hindbrain herniation on intraoperative scans while one was mild. In contrast, on postnatal studies 5 of 9 patients had no evidence of hindbrain herniation, while the other 4 had only mild herniation. Intra-uterine myelomeningocele repair appears to reverse preexisting hindbrain herniation. It is postulated that continuous flow of cerebrospinal fluid through the neural placode is the force responsible for inducing migration of the cerebellum and brain stem downward through the foramen magnum. By interrupting that flow during gestation, intrauterine myelomeningocele repair enables the cerebellum and brain stem to resume a normal, or nearly normal, configuration.

The increased use of the intrauterine contraception (IUC) in female population and its probable relationship with cervical squamous intraepithelial lesions and cervical cancer make necessary clarify the possible interaction between the device and the pre-neoplastic lesions. Seven hundred and eighty-nine patients users of IUC and 1491 patients ever users of IUC were followed every 6 months for 3 years. Each clinical control included Papanicolau test, colposcopy, HPV-DNA test and HPV-mRNA test. Also, in patients IUC users we analyzed the type of device, years of use and average age. Cytological sampling, histological examination, HPV-DNA test and HPV-mRNA test showed that there are not significantly differences between patients with or without IUC. None difference arose regarding persistence and progression between patients IUC users and IUC no users, for this reason, intrauterine contraception does not seem to be a co-causal factor in the possible development of cervical cancer.

Bacteriological cultures of material were collected from the endometrium and cervix of 150 women using the IUD, 75 control women and transfundally from 20 uteri of women who had undergone abdominal hysterectomy. The results show that the IUD does not alter the endometrial flora unless it is left in situ for a period exceeding two years. The transfundal cultures yielded the lowest positive cultures. The relationship of positive culture to the cycle and the period of insertion of IUD is discussed.

We report two cases of pelviperitoneal actinomycosis appearing in two young women with acute low abdominal pain. Abdominal CT demonstrated multiple solid or encapsulated peritoneal masses with marked contrast enhancement and infiltration of the adjacent mesenteric fat. Laparoscopy confirmed the presence of intraperitoneal abscesses which contained Actinomyces israelii. High doses of amoxicillin and clavulanic acid (Augmentine) were given and following CT scan after 2 and 6 weeks showed a slow, but complete, resolution of the lesions. Although the radiologic presentation of actinomycosis is nonspecific, the diagnosis should be raised in the presence of pseudotumoral mesenteric infiltration, particularly in young women with an IUD. Abdominal CT is a useful method for diagnosis and for follow-up. (orig./MG)

Full Text Available Intrauterine growth restriction refers to the inability of the fetus to reach its genetically determined potential size. Fetal growth restriction affects approximately 5–15% of all pregnancies in the United States and Europe. In developing countries the occurrence varies widely between 10 and 55%, impacting about 30 million newborns per year. Besides having high perinatal mortality rates these infants are at greater risk for severe adverse outcomes, such as hypoxic ischemic encephalopathy and cerebral palsy. Moreover, reduced fetal growth has lifelong health consequences, including higher risks of developing metabolic and cardiovascular diseases in adulthood. Numerous reports indicate placental insufficiency as one of the underlying causes leading to altered fetal growth and impaired placental capacity of delivering nutrients to the fetus has been shown to contribute to the etiology of intrauterine growth restriction. Indeed, reduced expression and/or activity of placental nutrient transporters have been demonstrated in several conditions associated with an increased risk of delivering a small or growth restricted infant. This review focuses on human pregnancies and summarizes the changes in placental amino acid, fatty acid, and glucose transport reported in conditions associated with intrauterine growth restriction, such as pre-eclampsia and young maternal age.
The intrauterine growth retardation (IUGR) takes second position after the premature births as an cause for neonate with smaller weight for it's gestational age. Perinatal morbidity of retard children is important, but perinatal mortality is about eight times higher then normal weighted neonates. It is very important to make the right diagnosis of IUGR, the cause of their illness, the therapy they need and when it's necessary to find the right time, place and way of birth. The prognosis of physical and neuropsychical health of retard children is unfavorable.

Fifteen cases were reviewed over a five-year period at a perinatal centre with intrauterine demise of one member of a multiple gestation. Nine cases were monozygotic twin pairs, two were dizygotic, and two were triples . Gestational age ranged from 27 to 39 weeks. The management protocol consisted of delivery in all cases after confirmation of the diagnosis. In 4 cases delivery was immediate because of spontaneous labor. In the other cases elective delivery was performed if the gestational age was 37 weeks or greater or there was evidence of preeclampsia or if amniocentesis revealed a mature lecithinsphingomyelin (L/S) ratio. Steroids were given if the L/S was immature or the attempt at amniocentesis was unsuccessful and delivery was performed 48 hours after initiation of steroid therapy. Cesarean section was the mode of delivery in 14 of the 15 cases. All of the cotwins and cotriplets survived. One survivor of a monozygous twin pair has multicystic encephalomalacia possibly implicating perinatal arterial occlusion or in utero disseminated intravascular coagulation (DIC). The intrauterine deaths are categorized into possibly avoidable deaths (2/15), unavoidable due to congenital anomalies (3/15), and unknown or unavoidable deaths (8/15).

Most contraceptive methods present benefits beyond contraception; however, despite a large body of evidence, many healthcare professionals (HCPs), users and potential users are unaware of those benefits. This review evaluates the evidence for non-contraceptive benefits of hormonal and non-hormonal contraceptive methods. We searched the medical publications in PubMed, POPLINE, CENTRAL, EMBASE and LILACS for relevant articles, on non-contraceptive benefits of the use of hormonal and intrauterine reversible contraceptive methods, which were published in English between 1980 and July 2014. Articles were identified using the following search terms: 'contraceptive methods', 'benefits', 'cancer', 'anaemia', 'heavy menstrual bleeding (HMB)', 'endometrial hyperplasia', 'endometriosis' and 'leiomyoma'. We identified, through the literature search, evidence that some combined oral contraceptives have benefits in controlling HMB and anaemia, reducing the rate of endometrial, ovarian and colorectal cancer and ectopic pregnancy as well as alleviating symptoms of premenstrual dysphoric disorder. Furthermore, the use of the levonorgestrel-releasing intrauterine system also controls HMB and anaemia and endometrial hyperplasia and cancer, reduces rates of endometrial polyps in users of tamoxifen and alleviates pain associated with endometriosis and adenomyosis. Depot medroxyprogesterone acetate controls crises of pain associated with sickle cell disease and endometriosis. Users of the etonogestrel-releasing contraceptive implant have the benefits of a reduction of pain associated with endometriosis, and users of the copper intrauterine device have reduced rates of endometrial and cervical cancer. Despite the high contraceptive effectiveness of many hormonal and intrauterine reversible contraceptive methods, many HCPs, users and potential users are concerned mainly about side effects and safety of both hormonal and non-hormonal contraceptive methods, and there is scarce information

Adolescent obesity has dramatically increased in recent decades, and along with that so have other medical comorbidities, such as hypertension, diabetes, hyperlipidemia, nonalcoholic steatohepatitis, polycystic ovary syndrome (PCOS), and pseudotumor cerebri. Obesity and related comorbidites may be contraindications to hormonal contraception, making contraception counseling of morbidly obese adolescents more challenging. Obese adolescent females seeking bariatric surgery need effective contraception in the postoperative period. This study is designed to determine the acceptance rate of the levonorgestrel-releasing intrauterine device (IUD) and describe common menstrual problems in obese adolescent bariatric surgery patients. This is a historic cohort study of adolescent females who underwent bariatric surgery over a 2-year period at a tertiary referral center for pediatric obesity. Data were systematically abstracted. The percent of patients with menstrual problems and the acceptance rate for the levonorgestrel-releasing IUD were determined. Twenty-five adolescents met inclusion criteria. The mean age was 17.4 years (standard deviation [SD] 2.6), and the mean body mass index (BMI) was 51.4 (SD 6.3) kg/m(2). Eighty-four percent were white. Twenty-eight percent had menorrhagia, 32% had oligomenorrhea, 40% had dysmenorrhea, and 36% had PCOS. Ninety-two percent (23 of 25) underwent IUD placement. There was a high prevalence of menstrual problems among this sample of severely obese adolescent females. The majority accepted the IUD, indicating it is a viable option among this population.

Vaginal delivery is recommended after intrauterine fetal death. However, little is known about the risk of shoulder dystocia in these deliveries. We studied whether intrauterine fetal death increases the risk of shoulder dystocia at delivery. In this population-based register study using the Medical Birth Registry of Norway, we included all singleton pregnancies with vaginal delivery of offspring in cephalic presentation in Norway during the period 1967-2012 (n = 2 266 118). Risk of shoulder dystocia was estimated as absolute risk (%) and odds ratio with 95% confidence interval. Adjustment was made for offspring birthweight (in grams). We performed sub-analyses within categories of birthweight (<4000 and ≥4000 g) and in pregnancies with maternal diabetes. Shoulder dystocia occurred in 1.1% of pregnancies with intrauterine fetal death and in 0.8% of pregnancies without intrauterine fetal death (p < 0.0001) (crude odds ratio 1.5, 95% confidence interval 1.2-4.9). After adjustment for birthweight, the odds ratio was 5.9 (95% confidence interval 4.7-7.4). In pregnancies with birthweight ≥4000 g, shoulder dystocia occurred in 14.6% of pregnancies with intrauterine fetal death and in 2.8% of pregnancies without intrauterine fetal death (p < 0.001) (crude odds ratio 5.9, 95% confidence interval 4.5-7.9). In pregnancies with birthweight ≥4000 g and concurrent maternal diabetes, shoulder dystocia occurred in 57.1% of pregnancies with intrauterine fetal death and 9.6% of pregnancies without intrauterine fetal death (p < 0.001) (crude odds ratio 12.6, 95% confidence interval 5.9-26.9). Intrauterine fetal death increased the risk of shoulder dystocia at delivery, and the absolute risk of shoulder dystocia was particularly high if offspring birthweight was high and the mother had diabetes. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Mantel-Haenszel odds ratio (OR) with 95% confidence interval (CI). Because of disparate interventions and outcome measures, we did not conduct meta-analysis. Five trials met the inclusion criteria. The studies included a total of 1503 women, with a mean of 301 participants. The trials compared the following contraceptives: combined oral contraceptive (COC) versus transdermal contraceptive patch, vaginal contraceptive ring, or levonorgestrel intrauterine system 20 µg/day (LNG-IUS 20); LNG-IUS 12 µg/day (LNG-IUS 12) versus LNG-IUS 16 µg/day (LNG-IUS 16); and LNG-IUS 20 versus the copper T380A intrauterine device (IUD). In the trials comparing two different types of methods, the study arms did not differ significantly for contraceptive efficacy or continuation. The sample sizes were small for two of those studies. The only significant outcome was that a COC group had a higher proportion of women who discontinued for 'other personal reasons' compared with the group assigned to the LNG-IUS 20 (OR 0.27, 95% CI 0.09 to 0.85), which may have little clinic relevance. The trial comparing LNG-IUS 12 versus LNG-IUS 16 showed similar efficacy over one and three years. In three trials that examined different LNG-IUS, continuation was at least 75% at 6 to 36 months. We considered the overall quality of evidence to be moderate to low. Limitations were due to trial design or limited reporting. Different doses in the LNG-IUS did not appear to influence efficacy over three years. In another study, continuation of the LNG-IUS appeared at least as high as that for the COC. The current evidence was insufficient to compare efficacy and continuation rates for hormonal and intrauterine contraceptive methods in women aged 25 years and younger.
Intrauterine growth restriction (IUGR) has been defined in several ways, but in general describes a condition in which the fetus exhibits poor growth in utero. This complication of pregnancy poses a significant public health burden as well as increased morbidity and mortality for the offspring. In human IUGR, alteration in fetal glucose and insulin homeostasis occurs in an effort to conserve energy and survive at the expense of fetal growth in an environment of inadequate nutrient provision. Several animal models of IUGR have been utilized to study the effects of IUGR on fetal glucose handling, as well as the postnatal reprogramming of energy metabolite handling, which may be unmasked in adulthood as a maladaptive propensity for cardiometabolic disease. This developmental programming may be mediated in part by epigenetic modification of essential regulators of glucose homeostasis. Several pharmacological therapies and nonpharmacological lifestyle modifications have shown early promise in mitigating the risk for or severity of adult metabolic phenotypes but still require further study of unanticipated and/or untoward side effects.

Full Text Available Abstract Background Vascular endothelial growth factor (VEGF, basic-fibroblast growth factor (b-FGF, and endothelial nitric oxide synthase (eNOS are factors that take part in placental angiogenesis. They are highly expressed during embryonic and fetal development, especially in the first trimester. In this study, we aimed to investigate the role of placental angiogenesis in the development of intrauterine growth restriction (IUGR by comparing the levels of expression of VEGF-A, b-FGF, and eNOS in normal-term pregnancy and IUGR placentas. Methods The expression of VEGF-A, b-FGF, and eNOS was studied using the avidin-biotin-peroxidase method in placental tissues diagnosed as normal (n = 55 and IUGR (n = 55. Results were evaluated in a semi-quantitative manner. Results The expression of all the markers was significantly higher (p Conclusion Increased expression of VEGF-A, b-FGF, and eNOS may be the result of inadequate uteroplacental perfusion, supporting the proposal that abnormal angiogenesis plays a role in the pathophysiology of IUGR.

Full Text Available Intrauterine growth restriction is a complication of pregnancy with a high probability of perinatal morbidity and mortality. It appears tobe caused by abnormal development of placental vasculature. Haemostatic processes are important for the development of the placenta,and an imbalance between procoagulant and anticoagulant factors has been associated with risk of intrauterine growth restriction.Objective. To evaluate coagulation abnormalities in placenta of pregnancies complicated with idiopathic intrauterine growth restriction.Materials and methods. Five placentas from pregnancies with idiopathic intrauterine growth restriction were compared to 19 controls.We performed gross and histological examination of the placenta. Analysis was made of both mRNA expression by real-time PCRand protein by ELISA of tissue factor and thrombomodulin in placental tissue. Results. Results based on histological evaluation wereconsistent with an increased prothrombotic state in placentas from pregnancies with idiopathic intrauterine growth restriction, andthrombosis of chorionic vessels was the most important finding. The study showed an increased expression of tissue factor protein(p=0.0411 and an increase in the ratio of tissue factor/thrombomodulin mRNA (p=0.0411 and protein (p=0.0215 in placentas frompregnancies with idiopathic intrauterine growth restriction. There were no statistically significant differences neither between cases andcontrols in the mRNA levels of tissue factor or thrombomodulin nor at the protein level of thrombomodulin. Conclusion. Evidence ofalteration of local haemostatic mechanisms at the level of the placenta, including abnormal expression of tissue factor and tissue factor/thrombomodulin ratio, in pregnancies that occur with idiopathic intrauterine growth restriction is presented.

Intrauterine contraceptives (IUCs), including the copper intrauterine device and the levonorgestrel-releasing intrauterine system (LNG-IUS), are among the reversible contraceptive methods with high effectiveness. However, use is low in many settings, including some Latin American countries, mainly due to the influences of myths, fears, and negative attitudes, not only of users and potential users, but also of different cadres of health care professionals. The purpose of this study was to assess the knowledge and attitudes of a group of Latin American obstetricians and gynecologists regarding IUCs. A survey was conducted during a scientific meeting organized in Chile in 2014 to present and discuss updated information about contraception. Obstetricians and gynecologists from 12 Latin American countries, who reported that they provide daily contraception services in both the public and private sectors, participated in the meeting. Participants who agreed to take part in the survey responded to a multiple-choice questionnaire on issues regarding knowledge, use, and attitudes about IUCs. Of the 210 obstetricians and gynecologists participating in the meeting, the respondents to each question varied from 168 (80.0%) to 205 (97.6%). Almost 50% recognized that the failure rate of combined oral contraceptives, patches, and vaginal rings is 8%-10%. Furthermore, 10% of the participants did not recognize the high contraceptive effectiveness of long-acting reversible contraceptive methods. Additionally, almost 80% of the respondents answered that they did not offer IUCs to nulligravidas and almost 10% did not offer IUCs to adolescents, albeit almost 90% of the respondents reported that nulligravidas are candidates for an LNG-IUS. Some deficiencies and contradictions in terms of knowledge and attitudes were identified from the answers of the Latin American obstetricians and gynecologists who participated in the survey. The knowledge and attitudes of health care professionals

Women with rare intrauterine contraception (IUC) failures are advised to have their IUC removed because of the risk of poor obstetric outcomes with a retained IUC. Specifics regarding IUC removal in early pregnancy including techniques for removal, rates of success, and immediate pregnancy outcomes following removal are not well described, however. The objective of this study was to identify women with an IUC in early pregnancy examined at a tertiary care center with the primary objective of describing IUC removal attempts, IUC removal successes, and pregnancy outcomes at 20 weeks following IUC removal. Case series of women with concurrent IUC and early pregnancy who presented to a tertiary care ultrasound center by 12 weeks' gestation. A total of 3116 women had an early pregnancy ultrasound during the study period. Nineteen (19/3116, 0.61%) women underwent ultrasounds that identified a pregnancy before 12 weeks and an IUC in the uterus. A copper IUC was identified in 11 women (11/19, 58%) on their first ultrasound, and a levonogestrel IUC was identified in 5 women (5/19, 26%). Seventeen (17/19, 88%) women attempted to remove their IUC; 11 of 69 (69%) were successfully removed on the first attempt. Fourteen (14/19; 74%) women with an IUC examined by 12 weeks' gestation had an ongoing pregnancy at 20 weeks compared with 1782 (1782/2678, 67%; P = 0.209) women without an IUC. Pregnancy with IUC is rare. Among the 19 women who were found to have an in situ IUC and early pregnancy, most had a successful IUC removal and had an ongoing pregnancy at 20 weeks' gestation. In our case series, IUC removal in the first trimester was a straightforward procedure and likely successful.

The purpose of this study was to determine whether intrauterine sound pressure levels produced by vibroacoustic stimulation were associated with distance from an intrauterine hydrophone in human parturients and to evaluate the effects of distance on the spectrum of the stimulus. Measurements of intrauterine sound were taken in eight volunteer parturients in normal active-phase labor by use of an intrauterine hydrophone. Vibroacoustic stimulation was performed on the maternal abdomen directly overlying the hydrophone; at distance of 5, 10, 15, 20, and 25 cm from the hydrophone; and at the maternal sternum. Intrauterine sound pressure levels were tape-recorded for later analysis. Fetal heart rate and fetal movement were assessed with each vibroacoustic stimulation. Spectral analyses were performed by taking the fast Fourier transform of the tape-recorded stimulation at each position. Analysis of variance with repeated measures indicated a statistically significant decrease (F = 4.1, p = 0.004) in the sound pressure levels as distance increased. Spectral analysis indicated large variability between and within subjects. Sound exposure of the fetal ear is on average decreased as the distance between the ear and the vibroacoustic stimulation is increased. The spectrum of the stimulus produced with vibroacoustic stimulation is highly variable.
Full Text Available Three-dimensional transvaginal ultrasonography was used to diagnose a septate uterus in a 24-year-old woman with infertility for 2 years. On infertility workup, semen analysis of her husband also revealed oligoasthenoteratospermia. Hysteroscopic metroplasty was performed successfully to resolve the uterine septum; however, subsequent in vitro fertilization and intracytoplasmic sperm injection yielded a blighted ovum requiring dilatation and curettage. After curettage, the patient had hypomenorrhea secondary to intrauterine synechiae and was treated with a hysteroscopic resectoscope and lysis of adhesions. Following these procedures, assisted reproductive technology was again implemented and resulted in a successful pregnancy. In our experience, three-dimensional transvaginal ultrasonography is a noninvasive, accurate, and easy method for the diagnosis of Müllerian duct anomalies, including septate uterus. Hysteroscopic metroplasty helps to normalize intrauterine cavity architecture. Additionally, it is important to repeat hysteroscopic examination when intrauterine adhesions are highly suspected.

Multiple cystic brain lesions in neonates have been described as a result of a variety of causes. All events described thus far in association with multicystic encephalomalacia (MCE) seem to point to hypoxic-ischaemic injury as the common factor for this particular form of central nervous system damage. We describe a neonate in whom repeated, prolonged episodes of intrauterine tachycardia had been documented. Congestive heart failure and fetal hydrops were present at birth and MCE at the age of 13 wk. The obvious relationship between this child's intrauterine tachycardia and his MCE points to the fact that any fetus with prolonged tachycardia should be considered at risk of severe brain damage.

Cystic encephalomalacia occurred in two preterm infants who had proven intrauterine herpes simplex virus type 2 infection. Calcification was evident in the basal ganglia. Follow-up scans indicated that the cysts had resolved over a period of two months in one infant, while in the case of the other, the cysts became progressively larger with significant ventricular dilatation developing. While cystic changes in the brain of preterm infants are usually due to periventricular leukomalacia, intrauterine infection needs to be considered as a possible cause. Antiviral treatment may be of benefit to infants with herpes simplex virus infection.

Intrauterine growth retardation (IUGR) is mainly due to a pathologic slow-down in the fetal growth pace, resulting in a fetus that is unable to reach its growth potential. IUGR frequency will vary depending on the discrimination criteria adopted. It is extremely important to use local or national fetal growth graphs in order to avoid some confounding factors. IUGR incidence in newborns would be between 3% and 7% of the total population. In our experience it is 5.13% a figure similar to the one obtained by other authors but with a progressively higher incidence during the last decade. There are multiple maternal factors that can generally be grouped into constitutional and general factors given that they affect age, weight, race, maternal cardiac volume, etc, socioeconomic factors with key incidence in the mother's nutrition level, where a poor maternal nutrition level would be the key factor in this group. We have evaluated multiple factors as possible contributors to the IUGR risk: race, parents' age, mother's height (cm), mother's birth weight and before pregnancy (kg), ponderal gain and blood pressure during pregnancy, and previous SGA newborns. Socioeconomic factors like social class, parents' profession, habitual residence, salary, immigration, and diet were also evaluated. We also included variables such as total daily working time and time mothers spent standing up, daily sleeping time (hrs), stress self-perception test at work and primiparity age. Toxic factors during pregnancy: tobacco (active and passive), alcohol, drugs and coffee consumption. Fetal or utero-placental factors were considered. In our study, the most significant etiologic factors were: Active and passive tobacco consuming, mother's stress level, increase of total months worked during pregnancy, total daily working hours and time mothers spent standing up and finally, the parent's height. Our data support the main objective of reducing the incidence of SGA newborns after IUGR by fighting

Executive functioning (EF), an umbrella construct encompassing gradual maturation of cognitive organization/management processes, is important to success in multiple settings including high school. Intrauterine tobacco exposure (IUTE) correlates with negative cognitive/behavioral outcomes, but little is known about its association with adolescent EF and information from real-life contexts is sparse. We evaluated the impact of IUTE on teacher-reported observations of EF in urban high school students controlling for covariates including other intrauterine and adolescent substance exposures. A prospective low-income birth cohort (51% male; 89% African American/Caribbean) was followed through late adolescence (16-18 years old). At birth, intrauterine exposures to cocaine and other substances (52% cocaine, 52% tobacco, 26% marijuana, 26% alcohol) were identified by meconium and/or urine assays, and/or maternal self-report. High school teachers knowledgeable about the student and unaware of study aims were asked to complete the Behavior Rating Inventory of Executive Functioning-Teacher Form (BRIEF-TF) annually. Teachers completed at least one BRIEF-TF for 131 adolescents. Multivariable analyses included controls for: demographics; intrauterine cocaine, marijuana, and alcohol exposures; early childhood exposures to lead; and violence exposure from school-age to adolescence. IUTE was associated with less optimal BRIEF-TF Behavioral Regulation scores (p <0.05). Other intrauterine substance exposures did not predict less optimal BRIEF-TF scores, nor did exposures to violence, lead, nor adolescents' own substance use. IUTE is associated with offspring's less optimal EF. Prenatal counseling should emphasize abstinence from tobacco, as well as alcohol and illegal substances. Copyright © 2017 Elsevier B.V.

Full Text Available Dorota Szostak-WegierekDepartment of Human Nutrition, Medical University of Warsaw, Warsaw, Poland Abstract: There is a growing body of evidence that improper intrauterine nutrition may negatively influence vascular health in later life. Maternal malnutrition may result in intrauterine growth retardation and, in turn, metabolic disorders such as insulin resistance, diabetes, hypertension, and dyslipidemia, and also enhanced risk of atherosclerosis and cardiovascular death in the offspring. Energy and/or protein restriction is the most critical determinant for fetal programming. However, it has also been proposed that intrauterine n-3 fatty acid deficiency may be linked to later higher blood pressure levels and reduced insulin sensitivity. Moreover, it has been shown that inadequate supply of micronutrients such as folate, vitamin B12, vitamin A, iron, magnesium, zinc, and calcium may contribute to impaired vascular health in the progeny. In addition, hypertensive disorders of pregnancy that are linked to impaired placental blood flow and suboptimal fetal nutrition may also contribute to intrauterine growth retardation and aggravated cardiovascular risk in the offspring. On the other hand, maternal overnutrition, which often contributes to obesity and/or diabetes, may result in macrosomia and enhanced cardiometabolic risk in the offspring. Progeny of obese and/or diabetic mothers are relatively more prone to develop obesity, insulin resistance, diabetes, and hypertension. It was demonstrated that they may have permanently enhanced appetites. Their atheromatous lesions are usually more pronounced. It seems that, particularly, a maternal high-fat/junk food diet may be detrimental for vascular health in the offspring. Fetal exposure to excessive levels of saturated fatty and/or n-6 fatty acids, sucrose, fructose and salt, as well as a maternal high glycemic index diet, may also contribute to later enhanced cardiometabolic risk.

To examine adolescent and young adults' priorities, values, and preferences affecting the choice to use an intrauterine contraceptive device (IUD). Qualitative exploratory study with analysis done using a modified grounded theory approach. Outpatient adolescent medicine clinic located within an academic children's hospital in the Bronx, New York. Twenty-seven women aged 16 to 25 years of age on the day of their IUD insertion. We conducted semistructured interviews exploring participant's decision making process around selecting an IUD. We were specifically interested in elucidating factors that could potentially improve IUD counseling. We identified 4 broad factors affecting choice: (1) personal; (2) IUD device-specific; (3) health care provider; and (4) social network. Most of the participants perceived an ease with a user-independent method and were attracted by the high efficacy of IUDs, potential longevity of use, and the option to remove the device before its expiration. Participants described their health care provider as being the most influential individual during the IUD decision-making process via provision of reliable, accurate contraceptive information and demonstration of an actual device. Of all people in their social network, mothers played the biggest role. Adolescents and young women who choose an IUD appear to value the IUDs' efficacy and convenience, their relationship with and elements of clinicians' contraceptive counseling, and their mother's support. Our results suggest that during IUD counseling, clinicians should discuss these device-specific benefits, elicit patient questions and concerns, and use visual aids including the device itself. Incorporating the factors we found most salient into routine IUD counseling might increase the number of adolescents and young women who choose an IUD as a good fit for them.

To investigate a possible correlation between maternal plasma homocysteine (HC) concentrations and intrauterine growth retardation (IUGR). The patients were divided into the IUGR group and controls. The IUGR group consisted of 40 women and their newborns with birth weight IUGR group and 4.6 ± 1.2 µmol/L in controls (p = 0.01). ROC curve analysis demonstrated that pulsatility index (PI), resistance index (RI) and HC concentrations were discriminative markers in IUGR group. According to Pearson correlation analysis there was a possible association between HC concentrations and PI, RI and middle cerebral artery Doppler velocimetry (MCA). Higher maternal HC concentration and lower birth weight were observed in the IUGR group as compared to the control group. We are of the opinion that maternal plasma homocysteine concentration may be a prognostic marker in intrauterine growth retardation.

The placenta represents a key organ for fetal growth as it acts as an interface between mother and fetus, regulating the fetal-maternal exchange of nutrients, gases, and waste products. During pregnancy, amino acids represent one of the major nutrients for fetal life, and both maternal and fetal concentrations are significantly different in pregnancies with intrauterine growth restriction when compared to uncomplicated pregnancies. The transport of amino acids across the placenta is a complex process that includes the influx of neutral, anionic, and cationic amino acids across the microvilluos plasma membrane of the syncytiotrophoblast, the passage through the cytoplasm of the trophoblasts, and the transfer outside the trophoblasts across the basal membrane into the fetal circulation. In this paper, we review the transport mechanisms of amino acids across the placenta in normal pregnancies and in pregnancies complicated by intrauterine growth restriction. PMID:22997583

ABSTRACT Trophoblast migration and invasion through the decidua and maternal uterine spiral arteries are crucial events in placentation. During this process, invasive trophoblast replace vascular endothelial cells as the uterine arteries are remodeled to form more permissive vessels that facilitate adequate blood flow to the growing fetus. Placentation failures resulting from either extensive or shallow trophoblastic invasion can cause pregnancy complications such as preeclampsia, intrauterine growth restriction, placenta creta, gestational trophoblastic disease and even maternal or fetal death. Consequently, the use of experimental animal models such as rats and mice has led to great progress in recent years with regards to the identification of mechanisms and factors that control trophoblast migration kinetics. This review aims to perform a comparative analysis of placentation and the mechanisms and factors that coordinate intrauterine trophoblast migration in humans, rats and mice under physiological and pathological conditions.

Hysteroscopy, which is a kind of endoscopy, makes it possible to evaluate macroscopically the cervical canal, uterine cavity, and the uterine opening of the oviducts. Laser hysteroscopy is used for removing septa and intrauterine adhesions, polyps, small submucosus myomas, and for endometrium ablation in abnormal metrorrhagias. The paper aims at the initial evaluation of laser hysteroscopy in removing intrauterine adhesions in the cases of 41 infertile women. Among all infertile patients 16 women (39%) conceived. Among others 1 woman (2.5%) did not want to conceive and 19 had other causes of infertility. Thirteen (93%) out of 14 patients with hypomenorrhea before surgery reported improvement of the menstruation cycle after the treatment. Five patients (12%) had adhesions for the second time. The patients had the second laser hysteroscopy. The control diagnostic hysteroscopy showed no adhesions in those cases.

1. Intrauterine infection or inflammation is common in cases of preterm birth. Preterm infants are at risk of acute respiratory distress as a result of lung immaturity; evidence of exposure to infection and/or inflammation before birth is associated with a reduced risk of neonatal respiratory distress syndrome (RDS). Experimentally induced intrauterine inflammation or infection in sheep causes a precocious increase in pulmonary surfactant in the preterm lungs that improves preterm lung function, consistent with the reduced risk of RDS in human infants exposed to infection and/or inflammation before birth. 2. The effects of intrauterine inflammation on fetal lung development appear to result from direct action of proinflammatory stimuli within the lungs rather than by systemic signals, such as the classical glucocorticoid-mediated lung maturation pathway. However, paracrine and/or autocrine production and/or metabolism of glucocorticoids in fetal lung tissue may occur as a result of inflammation-induced changes in the expression of 11β-hydroxysteroid dehydrogenase (types 1 and 2). 3. Likely candidates that mediate inflammation-induced surfactant production by the preterm lung include prostaglandin E₂ and/or other arachidonic acid metabolites. Intrauterine inflammation induces the expression of enzymes responsible for prostaglandin production in fetal lung tissue. Inhibition of prostaglandin production prevents, at least in part, the effects of inflammation on fetal lungs. 4. Our experiments are identifying mechanisms of surfactant production by the preterm lungs that may be exploited as novel therapies for preventing respiratory distress in preterm infants. Elucidation of the effects of inflammation on the fetal lungs and other organs will allow more refined approaches to the care of preterm infants exposed to inflammation in utero.

An infant with intrauterine brain death accompanied by pulmonary hypoplasia is reported. The fetus was delivered after 36 weeks gestation, 5 weeks after fetal movements ceased. The child died 4 h after birth. Pulmonary hypoplasia and remote brainstem necrosis associated with multicystic encephalomalacia were found at autopsy. These findings suggest that damage to brainstem respiratory centres had led to pulmonary hypoplasia through the absence of fetal respiratory movement.

Full Text Available Placental insufficiency, high altitude pregnancies, maternal obesity/diabetes, maternal undernutrition and stress can result in a poor setting for growth of the developing fetus. These adverse intrauterine environments result in physiological changes to the developing heart that impact how the heart will function in postnatal life. The intrauterine environment plays a key role in the complex interplay between genes and the epigenetic mechanisms that regulate their expression. In this review we describe how an adverse intrauterine environment can influence the expression of miRNAs (a sub-set of non-coding RNAs and how these changes may impact heart development. Potential consequences of altered miRNA expression in the fetal heart include; Hypoxia inducible factor (HIF activation, dysregulation of angiogenesis, mitochondrial abnormalities and altered glucose and fatty acid transport/metabolism. It is important to understand how miRNAs are altered in these adverse environments to identify key pathways that can be targeted using miRNA mimics or inhibitors to condition an improved developmental response.
Full Text Available Management of foetal distress is a subject of gynaecological interest, but an anaesthesiologist should know about resuscitation, because he should be able to treat the patient, whenever he is directly involved in managing the parturient patient during labour analgesia and before an emergency operative delivery. Progressive asphyxia is known as foetal distress; the foetus does not breathe directly from the atmosphere, but depends on maternal circulation for its oxygen requirement. The oxygen delivery to the foetus depends on the placental (maternal side, placental transfer and foetal circulation. Oxygen transport to the foetus is reduced physiologically during uterine contractions in labour. Significant impairment of oxygen transport to the foetus, either temporary or permanent may cause foetal distress, resulting in progressive hypoxia and acidosis. Intrauterine foetal resuscitation comprises of applying measures to a mother in active labour, with the intention of improving oxygen delivery to the distressed foetus to the base line, if the placenta is functioning normally. These measures include left lateral recumbent position, high flow oxygen administration, tocolysis to reduce uterine contractions, rapid intravenous fluid administration, vasopressors for correction of maternal hypotension and amnioinfusion for improving uterine blood flow. Intrauterine Foetal Resuscitation measures are easy to perform and do not require extensive resources, but the results are encouraging in improving the foetal well-being. The anaesthesiologist plays a major role in the application of intrauterine foetal resuscitation measures.

To assess the success and factors affecting early intrauterine device (IUD) provision after first trimester medical termination of pregnancy (MTOP). Subgroup analysis of a randomized contraceptive trial assessing the long-term effects of early provision of intrauterine contraception following abortion. Altogether, 606 women undergoing MTOP were included and followed for 3 months. The intervention group (n=307) was offered an IUD (either the levonorgestrel-releasing intrauterine system or copper-IUD) at a follow-up visit 1-4 weeks after MTOP. The control group (n=299) contacted primary health care for follow-up and contraceptive provision. Adverse events (infections, bleeding, residual tissue and incomplete abortion) were analyzed on intention-to-treat basis and IUD expulsions on per-protocol (PP) basis. In the intervention group, 234 women (76.2%) received the IUD as scheduled, 46 later (altogether 91.2%). In the control group, the corresponding figures were 8 (2.7%) and 64 [altogether 24.1%, Odds ratio (OR) (95% Confidence interval (CI))=32.7 (20.3-52.6)]. Eighty-five (27.7%) women in the intervention group and 38 (12.7%) in the control group received treatment (administration of antibiotics, misoprostol or surgical evacuation) because of presumed adverse event [2.63 (1.72-4.01)], mainly residual tissue. In the control group, 23 (60.5%) of these occurred during the first 2 weeks. IUD expulsion occurred in 12 (5.4%) of the 222 women in the intervention group (PP basis). When provided as part of abortion service, most early insertions following MTOP were performed as planned. The main reason for postponement was overdiagnosis of adverse events suspected at follow-up. The rate of IUD expulsion was similar to that reported previously. Early insertion following MTOP is safe, and the rate of IUD expulsion is low. Most adverse events possibly delaying IUD insertion occur early. Based on timing of adverse events in the control group, IUD insertion at approximately 2 weeks

Can the need of subsequent abortion be reduced by providing intrauterine contraception as a part of the abortion service? Provision of intrauterine devices (IUDs) in association with first trimester abortion more than halved the incidence of repeat abortion during the first year of follow-up. Following abortion, the incidence of subsequent abortion is high, up to 30-40%. In cohort studies, intrauterine contraception has reduced the need of repeat abortion by 60-70%. A randomized controlled trial. The main outcome measure was the incidence of subsequent induced abortions during the follow-up. Altogether 751 women seeking first trimester induced abortion were recruited and randomized into two groups. Randomization was accomplished by computer-assisted permuted-block randomization with random block sizes of four to six. The investigators did not participate in randomization, which was done before commencing the study. The participants were recruited between 18 October 2010 and 21 January 2013. The inclusion criteria were age ≥18 years, duration of pregnancy ≤12 weeks, accepting intrauterine contraception, residence in Helsinki and signing the informed consent form. Women with contraindications to intrauterine contraception, such as uterine anomaly, acute genital infection or pap-smear change requiring surgical treatment were ineligible to participate.This study was conducted in collaboration between the Department of Obstetrics and Gynaecology, University of Helsinki and Helsinki University Hospital, and Centralized family planning of the City of Helsinki.The intervention group (n = 375) was provided with intrauterine contraception (either the levonorgestrel-releasing intrauterine system or copper-releasing intrauterine device) immediately following surgical abortion (18.1%) or at a follow-up 2-4 weeks after medical abortion (81.9%). Women in the control group were prescribed oral contraceptives and advised to contact their primary healthcare unit for a follow

In altricial species such as the rat and mouse, there is good evidence for the intra-uterine programming of the endocrine pancreas. Changes in the intra-uterine nutritional environment cause alterations in the structure and function of the islets which have life-long effects and predispose the animal to glucose intolerance and diabetes in later life. In rodents, the islets develop relatively late in gestation and undergo substantial remodelling in the period immediately after birth. Hence, the critical window for islet development in these animals is short and readily accessible for experimental manipulation. The short life-span of these species also means that elderly animals can be studied within a reasonable time frame. In precocious species, such as guinea pigs and farm animals, intra-uterine programming of the endocrine pancreas is less well established. In part, this may be due to difficulties in identifying the critical window for development as islet formation and remodelling begin at an earlier stage of gestation and continue for longer after birth. The long life-span of these animals and the relative insulin resistance of adult ruminants compared to other species also make it difficult to establish whether fetal changes in islet development have long-term consequences. In the human, the main phase of islet development occurs during the second trimester, although remodelling occurs throughout late gestation and early childhood. There is, therefore, a relatively long period in which early changes in islet development could be reversed or ameliorated in the human. Although the human epidemiological observations suggest that the fetal origin of adult glucose intolerance is due primarily to changes in insulin sensitivity rather than to defective insulin secretion, subtle changes in islet morphology and function sustained in utero may well contribute to the increased susceptibility to type 2 diabetes observed in adults who were growth-retarded in utero.

Several groups have begun to explore the feasibility and utility of intrauterine closure of myelomeningocele. A subset of these fetuses have defects which fall into the category of myeloschisis, and therefore have inadequate skin to enable primary closure. After considerable discussion, it was decided to utilize bipedicular flaps to close these lesions. The procedure is described, and representative examples are shown. To date, 13 of 56 fetuses have required this approach for closure in utero. While this technique generally provides adequate coverage of the dural sac, the cosmetic results have been less than optimal. Copyright 2000 S. Karger AG, Basel

This article reviews the clinical experience with the GyneFix intrauterine implant system for interval, emergency and post-abortal contraception. The relatively high rate of unintended pregnancies and abortions in the world signifies that greater access to contraception is necessary. Unwanted pregnancies and abortions could be avoided by widening the range of effective and acceptable contraceptive methods for use in situations where current methods are far from optimal. High effectiveness, protection against sexual transmitted infections, long duration of action, reversibility and safety are some of the most important attributes of contraceptives valued by women. The development of the frameless intrauterine device is a response to the need to develop contraceptives with high user continuation rate. GyneFix has the lowest failure rate of all copper IUDs currently available. Its performance is further optimised by the atraumatic frameless design which minimises the side effects and discomfort experienced with conventional IUDs. GyneFix could, therefore, be a useful new contraceptive option in looking at ways to reduce the number of unwanted pregnacies and induced abortions.
Full Text Available The aim of this study was to examine the intra-uterine exposure to Sarcocystis spp. antigens, determining the number of foals with detectable concentrations of antibodies against these agents in the serum, before colostrum ingestion and collect data about exposure of horses to the parasite. Serum samples were collected from 195 thoroughbred mares and their newborns in two farms from southern Brazil. Parasite specific antibody responses to Sarcocystis antigens were detected using the indirect immunofluorescent antibody test (IFAT and immunoblot analysis. In 84.1% (159/189 of the pregnant mares and in 7.4% (14/189 of foals we detected antibodies anti-Sarcocystis spp. by IFAT. All samples seropositive from foals were also positive in their respective mares. Serum samples of seropositive foals by IFAT, showed no reactivity on the immunoblot, having as antigens S. neurona merozoites. In conclusion, the intra-uterine exposure to Sarcocystis spp. antigens in horses was demonstrated, with occurrence not only in mares, but also in their foals, before colostrum ingestion these occurrences were reduced.

Intrauterine Candida albicans infection causes severe fetal inflammatory responses and fetal injury in an ovine model. We hypothesized that intra-amniotic antifungal therapy with fluconazole would decrease the adverse fetal effects of intra-amniotic C. albicans in sheep. Sheep received an intra-amniotic injection of 10(7) colony-forming units C. albicans. After 2 d, animals were then randomized to: (i) intra-amniotic and fetal intraperitoneal saline with delivery after 24 h (3 d C. albicans group); (ii) intra-amniotic and fetal intraperitoneal injections of fluconazole with delivery after either 24 h (3 d C. albicans plus 1 d fluconazole group) or 72 h (5 d C. albicans plus 3 d fluconazole group). Controls received intra-amniotic injections of saline followed by intra-amniotic and fetal intraperitoneal fluconazole injections. Intra-amniotic C. albicans caused severe fetal inflammatory responses characterized by decreases in lymphocytes and platelets, an increase in posterior mediastinal lymph node weight and proinflammatory mRNA responses in the fetal lung, liver, and spleen. Fluconazole treatment temporarily decreased the pulmonary and chorioamnion inflammatory responses. The severe fetal inflammatory responses caused by intra-amniotic C. albicans infection were transiently decreased with fluconazole. A timely fetal delivery of antimicrobial agents may prevent fetal injury associated with intrauterine infection.
Full Text Available The causes of intrauterine growth restriction (IUGR are multifactorial with both intrinsic and extrinsic influences. While many studies focus on the intrinsic pathological causes, the possible long-term consequences resulting from extrinsic intrauterine physiological constraints merit additional consideration and further investigation. Infants with IUGR can exhibit early symmetric or late asymmetric growth abnormality patterns depending on the fetal stage of development, of which the latter is most common occurring in 70–80% of growth-restricted infants. Deformation is the consequence of extrinsic biomechanical factors interfering with normal growth, functioning, or positioning of the fetus in utero, typically arising during late gestation. Biomechanical forces play a critical role in the normal morphogenesis of most tissues. The magnitude and direction of force impact the form of the developing fetus, with a specific tissue response depending on its pliability and stage of development. Major uterine constraining factors include primigravida, small maternal size, uterine malformation, uterine fibromata, early pelvic engagement of the fetal head, aberrant fetal position, oligohydramnios, and multifetal gestation. Corrective mechanical forces similar to those that gave rise to the deformation to reshape the deformed structures are often used and should take advantage of the rapid postnatal growth to correct form.

Importance Intrauterine fetal death or stillbirth occurs in approximately 1 out of every 160 pregnancies and accounts for 50% of all perinatal deaths. Postmortem evaluation fails to elucidate an underlying cause in many cases. Long QT syndrome (LQTS) may contribute to this problem. Objective To determine the spectrum and prevalence of mutations in the 3 most common LQTS susceptible genes (KCNQ1, KCNH2, and SCN5A) for a cohort of unexplained cases. Design, Setting, and Patients In this case series, retrospective postmortem genetic testing was conducted on a convenience sample of 91 unexplained intrauterine fetal deaths (mean [SD] estimated gestational age at fetal death, 26.3 [8.7] weeks) that were collected from 2006-2012 by the Mayo Clinic, Rochester, Minnesota, or the Fondazione IRCCS Policlinico San Matteo, Pavia, Italy. More than 1300 ostensibly healthy individuals served as controls. In addition, publicly available exome databases were assessed for the general population frequency of identified genetic variants. Main Outcomes and Measures Comprehensive mutational analyses of KCNQ1 (KV7.1, LQTS type 1), KCNH2 (HERG/KV11.1, LQTS type 2), and SCN5A (NaV1.5, LQTS type 3) were performed using denaturing high-performance liquid chromatography and direct DNA sequencing on genomic DNA extracted from decedent tissue. Functional analyses of novel mutations were performed using heterologous expression and patch-clamp recording. Results The 3 putative LQTS susceptibility missense mutations (KCNQ1, p.A283T; KCNQ1, p.R397W; and KCNH2[1b], p.R25W), with a heterozygous frequency of less than 0.05% in more than 10000 publicly available exomes and absent in more than 1000 ethnically similar control patients, were discovered in 3 intrauterine fetal deaths (3.3% [95% CI, 0.68%-9.3%]). Both KV7.1-A283T (16-week male) and KV7.1-R397W (16-week female) mutations were associated with marked KV7.1 loss-of-function consistent with in utero LQTS type 1, whereas the HERG1b-R25W mutation

Intrauterine infection can exacerbate postnatal hyperoxic lung injury. We hypothesized that antenatal betamethasone treatment attenuates hyperoxic lung injury aggravated by intrauterine infection in neonatal rats. Newborn Sprague-Dawley rats were divided into eight experimental groups according to (i) whether rats were exposed to normoxia (N) or hyperoxia (H, 85% oxygen) from postnatal day (P)1 to P14, (ii) whether antenatal betamethasone (0.2 mg/dose) or vehicle was administered to pregnant rats at gestation days (E)19 and E20, and (iii) whether intrauterine infection was induced or not antenatally. Intrauterine infection was induced by intracervical inoculation of Escherichia coli into pregnant rats on E19. We measured cytokine levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-1β in P1 rat lungs and performed morphometric analyses and assessed inflammatory responses in lung tissue and bronchoalveolar lavage (BAL) at P14 by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) staining and measurement of myeloperoxidase activity, collagen, and cytokine levels. Cytokine levels in P1 rat lungs were increased by intrauterine infection, and these increases were attenuated by antenatal betamethasone. Hyperoxic lung injuries, indicated by morphometric changes and an inflammatory response in the lung and BAL fluid, were aggravated by intrauterine infection at P14. This aggravation was significantly attenuated by antenatal betamethasone. Antenatal betamethasone attenuated aggravated hyperoxic lung injuries induced by intrauterine infection in neonatal rats via its anti-inflammatory actions.

To explore the risk factors for intrauterine adhesions in patients with artificial abortion and clinical efficacy of hysteroscopic dissection. 1500 patients undergoing artificial abortion between January 2014 and June 2015 were enrolled into this study. The patients were divided into two groups with or without intrauterine adhesions. Univariate and Multiple logistic regression were conducted to assess the effects of multiple factors on the development of intrauterine adhesions following induced abortion. The incidence rate for intrauterine adhesions following induced abortion is 17.0%. Univariate showed that preoperative inflammation, multiple pregnancies and suction evacuation time are the influence risk factors of intrauterine adhesions. Multiple logistic regression demonstrates that multiple pregnancies, high intrauterine negative pressure, and long suction evacuation time are independent risk factors for the development of intrauterine adhesions following induced abortion. Additionally, intrauterine adhesions were observed in 105 mild, 80 moderate, and 70 severe cases. The cure rates for these three categories of intrauterine adhesions by hysteroscopic surgery were 100.0%, 93.8%, and 85.7%, respectively. Multiple pregnancies, high negative pressure suction evacuation and long suction evacuation time are independent risk factors for the development of intrauterine adhesions following induced abortions. Hysteroscopic surgery substantially improves the clinical outcomes of intrauterine adhesions.

We report a case of a 30-year-old woman with an intrauterine device (IUD) improperly inserted deep within the myometrium, with a muscularis layer injury of the recto-sigmoid colon resulting of a uterine perforation and presented as abdomino-pelvic pain and dyspareunia. The ultrasonographic control of the IUD after the insertion (performed seven months before) was not checked. Cervical examination showed the strings of the IUD. The ultrasonographic exploration identified an intra-myometrial IUD with fundus perforation of the uterus. A laparoscopic exploration permitting the removal of the IUD revealed an insertion through the bowel wall. The lessons to draw of about this case report are discussed through a brief review of the literature. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Hyperthyroidism can manifest very early in fetal life (fetal thyrotoxicosis) or immediately after birth (neonatal thyrotoxicosis). The authors describe outcome of pregnancies in a woman with Graves' disease who received medical management and underwent subtotal thyroidectomy. The first pregnancy resulted in macerated stillbirth at 32 wk. Fetal tachycardia was followed by intrauterine death at 30 wk in the second pregnancy and macerated stillbirth at 26 wk in the third pregnancy. Fetal tachycardia was detected at 17 wk in the fourth pregnancy. Treatment with carbimazole along with thyroxine was followed by a live birth at 35 wk; but the baby developed severe fatal neonatal thyrotoxicosis with crisis on day 9 and died on day 12. Fetal tachycardia was noted in the fifth pregnancy as well and she was treated with carbimazole and thyroxine. She delivered a male baby at 37 wk. He developed neonatal hypothyroidism on day 8 which was controlled with thyroxine.
Hypospadias is one of the most common congenital malformations of the genitourinary tract in males. It is an incomplete fusion of urethral folds early in fetal development and may be associated with other malformations of the genital tract. The etiology is poorly understood and may be hormonal, genetic, or environmental, but most often is idiopathic or multifactorial. Among many possible risk factors identified, of particular importance is low birth weight, which is defined in various ways in the literature. No mechanism has been identified for the association of low birth weight and hypospadias, but some authors propose placental insufficiency as a common inciting factor. Currently, there is no standardized approach for evaluating children with hypospadias in the setting of intrauterine growth restriction. We reviewed the available published literature on the association of hypospadias and growth restriction to determine whether it should be considered a separate entity within the category of disorders of sexual differentiation.

The levonorgestrel intrauterine system (LNG-IUS) is an underused contraceptive method in adolescent populations. In addition to being a highly effective, reversible, long-acting contraception, the LNG-IUS has many noncontraceptive health benefits including reduced menstrual bleeding, decreased dysmenorrhea and pelvic pain related to endometriosis, and menstruation suppression in teens with physical or developmental disabilities. The LNG-IUS can also provide endometrial protection in teens with chronic anovulation, and may be used to treat endometrial hyperplasia and cancer. This review examines the evidence supporting the use of the LNG-IUS in adolescents for these noncontraceptive benefits. Copyright © 2013 Society for Adolescent Health and Medicine.

Inositol is a cyclic sugar alcohol which occurs naturally in a variety of stereoisomers, the most common of which is myo-inositol. Inositol phosphoglycan molecules have been isolated from mammalian tissues and are a major component of the intracellular mediators of insulin action. The fetus with intrauterine growth retardation (IUGR) activates a series of adaptive mechanisms to increase the chances for survival, such as a saving of glucose to ensure nutrition of the vital organs, with a consequent reduction in insulin secretion. It can be hypothesized that the reduced production of fetal insulin leads to an excretion of inositol from the intracellular to the extracellular compartment, with a consequent increase of the metabolite in plasma and urine and a decrease inside the cells. Recently, reports suggesting that the increase in extracellular myo-inositol may be a valid marker of an altered glucose metabolism during fetal development in IUGR have been published.

The use of vesicoamniotic shunt in the case of obstructive uropathy was described. On the base of ultrasound screening it has been diagnosed urethral obstruction. This abnormality of urinary tract was found in male fetus. It has been diagnosed the posterior urethral valve. Qualification to intrauterine therapy was based on normal parameters of renal function. Under ultrasound guidance the vesicoamniotic shunt was installed. The normal drenage was observed within 6 weeks, until it was dislocated. In 36th week of gestation the cesarean section was performed. The indications were signs of urethral obstruction. The boy was born in whom posterior urethral valves were recognized. He was born in good condition without any biochemical features of renal damage as well as signs of hypoplastic lung.

Low-dose aspirin (LDA) has been used for several years for the prevention of preeclampsia (PE). LDA started in early pregnancy is associated with improvement of placental implantation. The best evidence suggest that LDA can prevent more than half of PE cases in high-risk women when started before 16 weeks of gestation. Moreover, LDA started in early pregnancy reduces the risk of other placenta-mediated complications such as intrauterine growth restriction (IUGR) and perinatal death. The efficacy of LDA has been demonstrated in women with abnormal first-trimester uterine artery Doppler or with prior history of chronic hypertension or preeclampsia. Copyright © 2016 Elsevier Inc.

To investigate whether intrauterine manipulation affects the direction or alters the frequency of endometrial wavelike activity. Prospective observational study. University hospital-based fertility clinic. Thirty-six patients undergoing intrauterine insemination (IUI). Ultrasound observation before and after IUI. Endometrial wave type and endometrial wave frequency before and after IUI. There was no difference in the direction and frequency of endometrial waves before and after IUI in 36 patients. Although the induction of uterine contractions by intrauterine manipulation has been suggested in the literature, the present study shows no contractions or induction of unfavorable (fundus to cervix) endometrial wavelike activity in 36 patients undergoing IUI.

Intrauterine coinfections have rarely been reported. However, pregnancies exposed to multiple sexually transmitted infectious agents and drugs are likely to occur with increasing frequency and lead to complex pathology in the newborn. Often it will be difficult to establish a diagnosis, above all when this has to be done retrospectively. A premature (34 weeks) newborn presented with a complex clinical picture after exposure to multiple infectious and noninfectious teratogens during gestation. Immunocytochemical staining of the placental membranes and parenchyma suggested intrauterine coinfection by herpes simplex virus (HSV) type 2 and cytomegalovirus. This case illustrates the importance of careful placental investigation with modern techniques for the diagnosis of intrauterine HSV infection and coinfections.

Full Text Available Abstract Background Around 80% of intrauterine growth restricted (IUGR infants are born at term. They have an increase in perinatal mortality and morbidity including behavioral problems, minor developmental delay and spastic cerebral palsy. Management is controversial, in particular the decision whether to induce labour or await spontaneous delivery with strict fetal and maternal surveillance. We propose a randomised trial to compare effectiveness, costs and maternal quality of life for induction of labour versus expectant management in women with a suspected IUGR fetus at term. Methods/design The proposed trial is a multi-centre randomised study in pregnant women who are suspected on clinical grounds of having an IUGR child at a gestational age between 36+0 and 41+0 weeks. After informed consent women will be randomly allocated to either induction of labour or expectant management with maternal and fetal monitoring. Randomisation will be web-based. The primary outcome measure will be a composite neonatal morbidity and mortality. Secondary outcomes will be severe maternal morbidity, maternal quality of life and costs. Moreover, we aim to assess neurodevelopmental and neurobehavioral outcome at two years as assessed by a postal enquiry (Child Behavioral Check List-CBCL and Ages and Stages Questionnaire-ASQ. Analysis will be by intention to treat. Quality of life analysis and a preference study will also be performed in the same study population. Health technology assessment with an economic analysis is part of this so called Digitat trial (Disproportionate Intrauterine Growth Intervention Trial At Term. The study aims to include 325 patients per arm. Discussion This trial will provide evidence for which strategy is superior in terms of neonatal and maternal morbidity and mortality, costs and maternal quality of life aspects. This will be the first randomised trial for IUGR at term. Trial registration Dutch Trial Register and ISRCTN

Our aim was to evaluate the size of the fetal thymus by sonography in pregnancies with intrauterine growth restriction (IUGR) and to search for a possible relationship between a small fetal thymus and adverse perinatal outcomes. The transverse diameter of the fetal thymus was prospectively measured in 150 healthy and 143 IUGR fetuses between 24 and 40 weeks' gestation. The fetuses with IUGR were further divided according to normal or abnormal Doppler assessment of the umbilical and middle cerebral arteries and ductus venosus. Measurements were compared with reference ranges from controls. To determine which perinatal outcomes were independently associated with a small fetal thymus, a multivariate logistic regression analysis was performed. Thymus size was significantly lower in IUGR fetuses compared to controls (P IUGR fetuses, thymus size was significantly smaller in IUGR fetuses with abnormal Doppler flow compared to normal flow (P IUGR fetuses was independently associated with early delivery (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.05-1.49; P= .023), respiratory distress syndrome (OR, 1.36; 95% CI, 1.09-1.78; P= .005), early neonatal sepsis (OR, 1.65; 95% CI, 1.11-2.42; P= .001), and a longer stay in the neonatal intensive care unit (OR, 1.33; 95% CI, 1.08-1.71; P = .017). Intrauterine growth restriction is associated with fetal thymic involution, and a small fetal thymus is an early indicator of adverse perinatal outcomes in pregnancies complicated by IUGR. © 2016 by the American Institute of Ultrasound in Medicine.

The paper describes the cases of 3 female health operators with implanted copper IUDs, developing menometrorrhagia some months after an increase of the working time in a Magnetic Resonance Imaging (MRI) Unit (1.5 T), that progressively disappeared when the previous organization, involving discontinuous work shifts at MRI, was re-established. No known factors possibly related to menometrorrhagia were evidenced in the 3 operators, supporting the hypothesis of a role of the exposure to the electromagnetic fields (EMF) induced by the MRI system in symptoms induction. The possible mechanism remains unsettled, but menometrorrhagia might be triggered by a phlogistic stimulus caused by EMF, possibly the low-frequency currents induced in the wires of the IUD during the movements of the operator inside the static magnetic field generated by the MRI permanent magnet. Until now, the problem of possible interactions between copper IUDs and EMF induced by MRI has been considered in patients undergoing imaging, but the possible risk in MRI Units operators has been largely neglected. To our knowledge, the occurrence of menometrorrhagia is not routinely checked in health surveillance of MRI operators, so these symptoms can pass unnoticed, especially if they are transitory. Therefore, underreporting is rather possible. The cases described here support the need for further research on this topic, especially considering the progressive diffusion of more powerful MRI scanners (3 T and more), and of the interventional magnetic resonance imaging, both potentially involving higher EMF exposures, and a large number of MRI female operators, possibly using IUDs. The possibility that MRI operators with implanted metallic IUDs can be included in the group of "workers at particular risk" according to the EU Directive 2004/40/EC should be considered.

The case of a primary ovarian actinomycosis developed during the use of a Szontágh--Szereday type plastic IUD is presented. After a radical operation the patient was discharged in a good condition but 40 days later had to be readmitted because of a pelvic and abdominal wall abscess. After local surgery and massive penicillin treatment she is free of complaints. It is assumed that the IUD had a pathomechanical role.

To demonstrate the feasibility of copper IUD insertion following cesarean deliveries and assess its safety. This is a prospective pilot study at Pikine national hospital from February 15 to November 15, 2012. Were evaluated the efficacy, incidence and spectrum of complications and continuation rates. Fifty-nine subjects were enrolled and 46 received an IUD. The average age of patients was 28 years. No patient had previously used IUDs. Forty-four patients (97.5%) were returned to the first follow-up visit at the first month, 41 patients (89.1%) at the second visit and 39 patients (86.9%) at the third visit. The rate of lost sight was 8.7%. Pain and bleeding were reported rarely: 2.3% at the first month, 4.9% at the third month and 7.7% at the sixth month for the bleeding and 6.8% at the first month, 2.4% at the third month and 2% at the sixth month for pain. The rate of expulsion was 2.2%. The insertion of the IUD following cesarean delivery has an acceptable rate of expulsion and no increased rate of adverse effects. This technique should be popularized. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

85 residents of the Tondo, Philippines who were IUD registrants at the Mary Johnston Hospital Family Planning Clinic were interviewed to determine which combination(s) of certain selected demographic variables have the potential for predicting persistence in IUD use. Data collected concerned length of use of the IUD, age, number of living children, education and income of the respondent at the time of adoption. Regression analysis using REGRESS program evaluation of t-values, F-values, Durbin Watson statistic coefficients of determination was the analysis undertaken. Predictions of persistence can be made from the single factors of age of respondent and the number of living children a woman has. Predictions can also be made from combinations of the following factors: number of living children and age of the respondent; number of living children and monthly family income; number of living children and educational achievement of the respondent; and age and monthly family income of the respondent.

Full Text Available Introduction - Placental mesenchymal dysplasia is a rare vascular disease associated with intrauterine growth restriction, fetal demise as well as Beckwith–Wiedemann syndrome. Some neonates present hematologic abnormalities possibly related to consumptive coagulopathy and hemolytic anemia in the placental circulation. Case report - We present a case of placental mesenchymal dysplasia in a fetus with intrauterine growth restriction and cerebellar hemorrhagic injury diagnosed in the 20th week of pregnancy. During 26th week, our patient had an intrauterine fetal demise in the context of gestational hypertension. We have detailed the ultrasound findings that made us suspect the presence of hematologic disorders during 20th week. Discussion - We believe that the cerebellar hematoma could be the consequence of thrombocytopenia accompanied by anemia. If hemorrhagic damage during fetal life is found, above all associates with an anomalous placental appearance and with intrauterine growth restriction, PMD should be suspected along other etiologies.

It has been theorized that fetal myelomeningocele repair may reduce ongoing intrauterine injury and perhaps allow healing and regeneration of dysplastic neural tissue. We report on the postnatal imaging studies of the first 4 patients to have undergone intrauterine myelomeningocele repair at our institution. Each of the 4 patients underwent postnatal sonographic and MRI. In addition, the postnatal ultrasounds of these 4 were compared to a group of retrospective controls. MRI scans of the 4 experimental subjects revealed no evidence of hindbrain herniation while other stigmata of the Chiari-II malformation persisted. In comparison to the retrospective controls this absence of herniation was distinctly unusual. Intrauterine myelomeningocele repair may reduce the degree of hindbrain herniation normally seen in patients with myelomeningocele. This raises the possibility that intrauterine repair may decrease the morbidity associated with the Chiari type-II malformation including brainstem dysfunction, hydrocephalus and syringomyelia.

Abstract. Tubal sterilization is a widely used permanent contraceptive method for women who had completed their desired childbearing. If a pregnancy occurs after tubal sterilization, it is expected to be ectopic in most of the cases. However encountering an intrauterine pregnancy after Pomeroy tubal sterilization is extremely rare. A second time intrauterine pregnancy occured in a 34-year-old woman who had undergone tubal sterilization by Pomeroy technique in her last caesarean section. We a...

Severe intrauterine anemia of unknown cause presents a diagnostic challenge. We describe a Norwegian case, managed successfully by intrauterine transfusions, that further investigations demonstrated to be due to a rare type of thalassemia. A deletion of the 5' end of the beta globin gene cluster was characterized, the breakpoints sequenced and a new type of epsilongammagammadeltabeta thalassemia identified. This case highlights the need to consider diagnoses of rare conditions not normally associated with a particular population.

The probability of an unclear very early pregnancy being a normal intrauterine pregnancy was estimated using a logistic model. Five diagnostic measures of prognostic value were identified in the model: (i) daily change in human chorionic gonadotrophin (HCG), (ii) results of transvaginal ultrasound, (iii) vaginal bleeding, (iv) serum progesterone level and (v) risk score for ectopic pregnancy. With the use of this model, the probability of a normal intrauterine pregnancy has been estimated as 96.7%.

Background Many obstacles to intrauterine contraception use exist, including provider and patient misinformation, high upfront cost, and clinician practice patterns. The aim of our study was to investigate knowledge and attitudes about intrauterine contraception among obstetricians and gynecologists in the area of Saint Louis. Study Design We mailed a self-administered, anonymous survey to 250 clinicians who provide obstetric and gynecologic care in Saint Louis City and County which included questions about demographics, training, family planning visits, and intrauterine contraceptive knowledge and use. Results The overall survey response rate among eligible clinicians was 73.7%. Clinicians who had recently finished training or saw higher numbers of contraceptive patients per week were more likely to insert intrauterine contraception than clinicians who completed training prior to 1989 or saw fewer contraceptive patients. Several misconceptions among clinicians were identified, including an association between intrauterine contraceptives and an elevated risk of pelvic inflammatory disease. Conclusions Physician misconceptions about the risks of intrauterine contraception continue to occur. Improved clinician education is greatly needed to facilitate the use of these highly effective, long-acting, reversible methods of contraception. PMID:20103447

In this systematic review and meta-analysis, the effect of intrauterine HCG infusion before embryo transfer on IVF outcomes (live birth rate, clinical pregnancy rate and spontaneous aboretion rate) was investigated. Searches were conducted on MEDLINE, EMBASE and The Cochrane Library. Randomized studies in women undergoing IVF and intracytoplasmic sperm injection comparing intrauterine HCG administration at embryo transfer compared with no intrauterine HCG were eligible for inclusion. Eight randomized controlled trials were eligible for inclusion in the meta-analysis. A total of 3087 women undergoing IVF and intracytoplasmic sperm injection cycles were enrolled (intrauterine HCG group: n = 1614; control group: n = 1473). No significant difference was found in the live birth rate (RR 1.13; 95% CI 0.84 to 1.53) and spontaneous abortion rate (RR 1.00, 95% CI 0.74 to 1.34) between women who received intrauterine HCG and those who did not receive HCG. Although this review was extensive and included randomized controlled trials, no significant heterogeneity was found, and the overall included numbers are relatively small. In conclusion the current evidence does not support the use of intrauterine HCG administration before embryo transfer. Well-designed multicentre trials are needed to provide robust evidence.

Full Text Available This study was undertaken to elucidate detailed event of early embryogenesis in chicken embryos using a noninvasive egg retrieval technique before oviposition. White Leghorn intrauterine eggs were retrieved from 95 cyclic hens aged up to 54-56 weeks and morphogenetic observation was made under both bright field and fluorescent image in a time course manner. Differing from mammals, asymmetric cleavage to yield preblastodermal cells was observed throughout early embryogenesis. The first two divisions occurred synchronously and four polarized preblastodermal cells resulted after cruciform cleavage. Then, asynchronous cleavage continued in a radial manner and overall cell size in the initial cleavage region was smaller than that in the distal area. Numerous sperms were visible, regardless of zygotic nuclei formation. Condensed sperm heads were present mainly in the perivitelline space and cytoplasm, and rarely in the yolk region, while decondensed sperm heads were only visible in the yolk. In conclusion, apparent differences in sperm dynamics and early cleavage events compared with mammalian embryos were detected in chick embryo development, which demonstrated polarized cleavage with penetrating supernumerary sperm into multiple regions.

Intrauterine contraception (IUC) is safe, highly effective and has few medical contraindications. Primary care providers see many women with chronic conditions who might benefit from IUC. We surveyed women aged 18-50 who visited one of four primary care clinics in Pennsylvania between October 2008 and April 2010 to investigate perceptions of IUC and to identify factors associated with accurate perceptions. Key independent variables included patient characteristics, including knowing other women who had used IUC, and having discussed IUC with a provider. Logistic regression was used to examine the association between independent variables and accurate perceptions. The study population included 1626 eligible respondents. Only 19.5% of women knew that IUC is more effective than oral contraceptive pills, 57.4% knew that IUC does not increase the risk of sexually transmitted infections and 28.7% knew that IUC is more cost-effective than oral contraceptive pills. Among women who had never used IUC, accurate perceptions were associated with higher levels of education, knowing one or more women who had used IUC and having discussed IUC with a health care provider. Many women seeking primary care have inaccurate perceptions of IUC and may benefit from counseling about the advantages of this approach to preventing unintended pregnancy. Published by Elsevier Inc.

Intrauterine growth restriction (IUGR) is a pathologic fetal condition known to affect the fetal brain regionally and associated with future neurodevelopmental abnormalities. This study employed MRI to assess in utero regional brain volume changes in IUGR fetuses compared to controls. Retrospectively, using MRI images of fetuses at 30-34 weeks gestational age, a total of 8 brain regions - supratentorial brain and cavity, cerebral hemispheres, temporal lobes and cerebellum - were measured for volume in 13 fetuses with IUGR due to placental insufficiency and in 21 controls. Volumes and their ratios were assessed for difference using regression models. Reliability was assessed by intraclass correlation coefficients (ICC) between two observers. In both groups, all structures increase in absolute volume during that gestation period, and the rate of cerebellar growth is higher compared to that of supratentorial structures. All structures' absolute volumes were significantly smaller for the IUGR group. Cerebellar to supratentorial ratios were found to be significantly smaller (P < 0.05) for IUGR compared to controls. No other significant ratio differences were found. ICC showed excellent agreement. The cerebellar to supratentorial volume ratio is affected in IUGR fetuses. Additional research is needed to assess this as a radiologic marker in relation to long-term outcome. (orig.)

Menorrhagia is a common problem, yet evidence to inform decisions about therapy is limited. In a pragmatic, multicenter, randomized trial, we compared the levonorgestrel-releasing intrauterine system (levonorgestrel-IUS) with usual medical treatment in women with menorrhagia who presented to their primary care providers. We randomly assigned 571 women with menorrhagia to treatment with levonorgestrel-IUS or usual medical treatment (tranexamic acid, mefenamic acid, combined estrogen-progestogen, or progesterone alone). The primary outcome was the patient-reported score on the Menorrhagia Multi-Attribute Scale (MMAS) (ranging from 0 to 100, with lower scores indicating greater severity), assessed over a 2-year period. Secondary outcomes included general quality-of-life and sexual-activity scores and surgical intervention. MMAS scores improved from baseline to 6 months in both the levonorgestrel-IUS group and the usual-treatment group (mean increase, 32.7 and 21.4 points, respectively; Pmenorrhagia who presented to primary care providers, the levonorgestrel-IUS was more effective than usual medical treatment in reducing the effect of heavy menstrual bleeding on quality of life.

Full Text Available Background/Aim. Intrauterine growth retardation (IUGR is a pathological condition of pregnancy characterised by birth weight below the 10th centile. A number of fetal, placental and maternal causes can lead to IUGR; although, in most cases no specific causes can be identified. The aim of this study was to determine the part of chromosomal abnormalities in IUGR etiology. Methods. Fetal blood karyotype taken by cordocentesis from 168 fetuses with diagnosed IUGR was analyzed. Results. Chromosomal rearrangements both numerical and structural were detected in 14 cases (12.2%. Two cases were triploid. Patau syndrome, Edwards syndrome and Down syndrome were found in two cases each. There was one case of trisomy 7 (47, XY, +7 and one case of trisomy 16 (47, XX, +16; one translocation, 46, XY, t (2; 14(q23; q32 and a deletion 46, XYdel (12 (p12 as well as two cases of sex chromosomes abnormalities, 45, X (Turner syndrome and 47, XYY. Conclusion. These findings suggest that a consistent number of symmetrical IUGR cases (about 12% can be associated with chromosomal rearrangements. Chromosomal aberrations that cause IUGR are heterogeneous, aberration of autosomes, mostly autosomal trisomies, being the most common.

Intrauterine growth restriction (IUGR) is a perinatal condition affecting foetal growth, with under the 10th percentile of the weight curve expected for gestational age. This condition has been associated with higher cardiovascular and metabolic risk and post-natal obesity. There are also major changes in placental function, and particularly in a key molecule in this regulation, nitric oxide. The synthesis of nitric oxide has numerous control mechanisms and competition with arginase for their common substrate, the amino acid L-arginine. This competition is reflected in various vascular diseases and particularly in the endothelium of the umbilical vessels of babies with IUGR. Along with this, there is regulation at the epigenetic level, where methylation in specific regions of some gene promoters, such as the nitric oxide synthase, regulating their expression. It is currently of great interest to understand the mechanisms by which diseases such as IUGR may be conditioned, particularly by maternal nutritional and metabolic conditions, and epigenetic mechanisms that could eventually be modifiable, and thus a focus of interest for health interventions.

Adolescents are at high risk for unintended pregnancies. Although intrauterine devices (IUDs), long-acting reversible contraceptives (LARCs), are known to be highly effective in preventing pregnancy, little is known about IUD adherence in adolescents. In this systematic review (SR) we examined IUD continuation rates compared with other forms of contraception in young women aged 25 years and younger. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A systematic search of Ovid Medline, Cochrane Library, and Embase was conducted for the years 1946-2015. Included studies examined IUD use in women 25 years of age and younger, compared IUD use with another form of contraception, and measured continuation rates at 12 months. The quality of each study was appraised using the Downs and Black criteria, and 12-month continuation rates among studies were pooled and analyzed according to contraceptive type. Of 3597 articles retrieved, 9 studies met criteria for SR. Synthesized across studies, 12-month continuation was significantly higher for IUD users (86.5%, 12,761/14,747) compared with oral contraceptives (39.6%, 1931/4873), Depo-Provera (Pfizer Inc, New York, NY) hormonal injection (39.8%, 510/1282), vaginal ring (48.9%, 196/401), and transdermal patch (39.8%, 37/93; all P values contraceptive methods for women aged 25 years and younger. In a population with high rates of unintended pregnancies, generally low adherence, and imperfect use with other non-LARCs, IUD use should be encouraged.

The adolescent pregnancy rate in Louisiana (LA) and Mississippi (MS) is one of the highest in the United States. One approach to decrease that rate is to increase contraceptive use. We sought to characterize LA and MS family physicians' (FPs) contraception counseling for adolescents with a focus on the intrauterine contraceptive device (IUD). DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Online survey of resident and practicing physician members of the LA and MS Academy of FPs. Three hundred ninety-eight of 1616 invited FPs responded; 244 were included in our analysis. When counseling adolescents about contraception, respondents "frequently discussed" oral contraceptives and condoms 87.5% (210/240) and 83.8% (202/241) of the time, respectively. Newer and more highly effective contraceptives such as the ring, patch, IUD, and implant were "frequently discussed" only 34.6% (82/237)-39.3% (92/234) of the time. In the previous 6 months, 56% (136/243) of respondents ever discussed an IUD with an adolescent. Respondents were more likely to have discussed IUDs if they learned IUD insertion during residency, had on-site access to IUD inserters, believed they were competent and/or comfortable with IUD counseling. In 5 clinical scenarios asking whether the respondent would recommend an IUD to a 17- or a 27-year-old patient (in all scenarios patients were eligible for an IUD), respondents were restrictive overall and significantly fewer would recommend an IUD for the adolescent. Our results suggest that there are missed opportunities for full-scope contraception counseling by LA and MS FPs. When these FPs counsel adolescents about contraception they less frequently discuss newer methods and more highly effective methods. Additionally many LA and MS FPs use overly restrictive eligibility criteria when considering IUDs. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

The advantages of intrauterine contraception (IUC) are well established (highly effective, low discontinuation rate, easy to use, low cost, and suitable for immediate postpartum use), but low levels of use in many countries and declining use in others are causes for concern. Due to the ongoing Zika virus outbreak, public health officials are calling for the continued practice of safe sex and the delay of pregnancy. Our study was conducted to assess the current situation of IUC availability and provision in Latin America and to determine the role of national policies in meeting the contraceptive needs of the populations in these countries. A survey was conducted in Latin America and the Caribbean between December 2015 and January 2016 to assess national policies with regard to IUC provision, availability and accessibility. 18 countries participated. All responding countries had national policies on IUC. Many in the public sector provided the intrauterine device (IUD) free of charge, but the levonorgestrel-releasing intrauterine system (LNG-IUS) was generally available in the private sector. Some countries had very restrictive policies on who was permitted to carry out IUC insertions, but most permitted a range of health professionals to do so. Immediate postpartum IUC insertion was uncommon. Some countries placed restrictions on IUC use in women who were nulliparous, young, at high risk of catching a sexually transmitted infection or who had multiple sexual partners. IUC is underused in Latin America. The study reveals policy level barriers that may impede access to IUC, one of the most effective, long-acting, non-hormonal, reversible contraceptive methods. Governments should consider reviewing and rethinking their policies on contraception to ensure IUC service provision among populations at high risk of unplanned pregnancy, especially those vulnerable to Zika virus.

It has been postulated that intrauterine myelomeningocele repair might improve neurologic outcome in patients with myelomeningocele. A total of 59 such procedures have been performed at Vanderbilt University. Preliminary results suggested that the degree of hindbrain herniation is reduced by intrauterine repair. In an attempt to further quantify the possible benefits of this surgery, a subset of these patients was brought back to Vanderbilt for study. A group of 26 patients who had undergone intrauterine myelomeningocele repair underwent an extensive evaluation which included manual muscle testing, MR imaging and precise determination of the anatomic level of their lesions as well as multiple other tests. The results of this analysis were compared to those in 2 groups of historical controls. In this group of patients intrauterine myelomeningocele repair substantially reduced the incidence of moderate to severe hindbrain herniation (4 vs. 50%). The incidence of shunt-dependent hydrocephalus was more modestly reduced (58 vs. 92%). The average level of leg function closely matched the average anatomic level of the lesion in both the fetal surgery and control groups. The most dramatic effect of intrauterine repair appears to be on hindbrain herniation. A less dramatic, but significant, reduction in shunt-dependent hydrocephalus is also seen. Prospective patients should be cautioned not to expect improvement in leg function as the result of this surgery. The potential benefits of surgery must be carefully weighed against the potential risks of prematurity.

Due high rates of unplanned pregnancy and unsafe abortion in young women in Latin America intrauterine contraception, by its great contraceptive efficacy, should be offered by the public services of health in a more generalized way. However, some negative prejudices prevail over the perception of its benefits. The aim of this article was to explore the most relevant myths around this contraceptive method in Latin America and make a review of the literature to allay the fears of their use by young and nulliparous women. Descriptive and retrospective study. Search for information in Embase and PubMed with emphasis on clinical randomized studies, studies of cases and controls, meta-analyses and systematic reviews which show risks and benefits of intrauterine contraception. Evidence shows that intrauterine contraception has few contraindications for young women and nulliparous; for this reason it must be as an effective public health strategy to reduce unplanned pregnancies and unsafe abortions. We identified the major barriers to the use of intrauterine contraception in Latin America and evidence for each one of them in the bibliography. Doctors of first contact in health systems should now recognize that intrauterine contraception is safe and effective.

Infants with intrauterine growth restriction (IUGR) are at increased risk for neonatal and lifelong morbidities affecting multiple organ systems including the intestinal tract. The underlying mechanisms for the risk to the intestine remain poorly understood. In this study, we tested the hypothesis that IUGR affects the development of goblet and Paneth cell lineages, thus compromising the innate immunity and barrier functions of the epithelium. Using a mouse model of maternal thromboxane A2-analog infusion to elicit maternal hypertension and resultant IUGR, we tested whether IUGR alters ileal maturation and specifically disrupts mucus-producing goblet and antimicrobial-secreting Paneth cell development. We measured body weights, ileal weights and ileal lengths from birth to postnatal day (P) 56. We also determined the abundance of goblet and Paneth cells and their mRNA products, localization of cellular tight junctions, cell proliferation, and apoptosis to interrogate cellular homeostasis. Comparison of the murine findings with human IUGR ileum allowed us to verify observed changes in the mouse were relevant to clinical IUGR. At P14 IUGR mice had decreased ileal lengths, fewer goblet and Paneth cells, reductions in Paneth cell specific mRNAs, and decreased cell proliferation. These findings positively correlated with severity of IUGR. Furthermore, the decrease in murine Paneth cells was also seen in human IUGR ileum. IUGR disrupts the normal trajectory of ileal development, particularly affecting the composition and secretory products of the epithelial surface of the intestine. We speculate that this abnormal intestinal development may constitute an inherent “first hit”, rendering IUGR intestine susceptible to further injury, infection, or inflammation. PMID:26745886

Intrauterine growth restriction (IUGR) is a pathologic fetal condition known to affect the fetal brain regionally and associated with future neurodevelopmental abnormalities. This study employed MRI to assess in utero regional brain volume changes in IUGR fetuses compared to controls. Retrospectively, using MRI images of fetuses at 30-34 weeks gestational age, a total of 8 brain regions-supratentorial brain and cavity, cerebral hemispheres, temporal lobes and cerebellum-were measured for volume in 13 fetuses with IUGR due to placental insufficiency and in 21 controls. Volumes and their ratios were assessed for difference using regression models. Reliability was assessed by intraclass correlation coefficients (ICC) between two observers. In both groups, all structures increase in absolute volume during that gestation period, and the rate of cerebellar growth is higher compared to that of supratentorial structures. All structures' absolute volumes were significantly smaller for the IUGR group. Cerebellar to supratentorial ratios were found to be significantly smaller (P IUGR compared to controls. No other significant ratio differences were found. ICC showed excellent agreement. The cerebellar to supratentorial volume ratio is affected in IUGR fetuses. Additional research is needed to assess this as a radiologic marker in relation to long-term outcome. • IUGR is a pathologic fetal condition affecting the brain • IUGR is associated with long-term neurodevelopmental abnormalities; fetal characterization is needed • This study aimed to evaluate regional brain volume differences in IUGR • Cerebellar to supratentorial volume ratios were smaller in IUGR fetuses • This finding may play a role in long-term development of IUGR fetuses.

Accurate fetal imaging is essential to the practice of maternal-fetal medicine. While ultrasonography has been the traditional mainstay of fetal imaging, its ability to resolve critical features of central nervous system (CNS) anatomy remains limited. As interest in intrauterine therapy for myelomeningocele has increased, so has the need for more accurate, noninvasive imaging of the CNS. Fetal magnetic resonance imaging (MRI) promises to fill the gap left by ultrasound. Thirty-seven MRI scans of fetuses previously diagnosed with myelomeningocele were reviewed by 2 neuroradiologists. The ability of fetal MRI to resolve the commonest CNS stigmata of spina bifida, and the incidence and extent of interobserver error, was assessed. In 4 cases, postnatal MRIs were also available. These were compared to the corresponding fetal studies. The imaging quality with the technique used in this study was excellent, even without the use of maternal or fetal sedation. There were no complications, and the imaging times were minimal. Interobserver error was minimal with respect to the evaluation of ventricular dilatation and hindbrain herniation, but moderate in the description and location of the spinal lesion. As had previously been documented with ultrasonography, a reduction was seen in hindbrain herniation when comparing pre- and postnatal MRIs. It is concluded that fetal MRI is an effective, noninvasive means of assessing fetal CNS anatomy. Its ability to resolve posterior fossa anatomy is superior to ultrasonography while, with respect to the evaluation of hydrocephalus and the level and nature of the spinal lesion, it may be equivalent to inferior. Inclusion of the fetal MRI into the standard diagnostic armamentarium will probably await the next major advance in speed and resolution. It is conceivable that, with further advances, MRI might supplant ultrasonography as the diagnostic tool of choice for evaluation of fetal anomalies including myelomeningocele. Copyright 2000 S

OBJECTIVE We sought to determine whether the success of intrauterine insemination (IUI) varies based on the type of health care provider performing the procedure. STUDY DESIGN This was a retrospective cohort study set at an infertility clinic at an academic institution. The patients who comprised this study were 1575 women who underwent 3475 IUI cycles from late 2003 through early 2012. Cycles were stratified into 3 groups according to the type of provider who performed the procedure: attending physician, fellow physician, or registered nurse (RN). The primary outcome was live birth. Additional outcomes of interest included positive pregnancy test and clinical pregnancy. Repeated measures log binomial regression was used to estimate the risk ratios (RR) and 95% confidence intervals (CI) for the outcomes and to evaluate the effect of potential confounders. All tests were 2-sided, and P values < .05 were considered statistically significant. RESULTS Of the 3475 IUI cycles, 2030 (58.4%) were gonadotropin stimulated, 929 (26.7%) were clomiphene citrate stimulated, and 516 (14.9%) were natural. The incidences of clinical pregnancy and live birth among all cycles were 11.8% and 8.8%, respectively. After adjusting for female age, male partner age, and cycle type, the incidence of live birth was similar for RNs compared with attending physicians (RR, 0.80; 95% CI, 0.58–1.1) and fellow physicians compared with attending physicians (RR, 0.84; 95% CI, 0.58–1.2). Similar results were seen for positive pregnancy test and clinical pregnancy. CONCLUSION There was no significant difference in live birth following IUI cycles in which the procedure was performed by a fellow physician or RN compared with an attending physician. PMID:24881820

Full Text Available Objectives: This descriptive study was performed to evaluate the capability of a non-invasive transabdominal electrocardiographic system to extract clear fetal electrocardiographic (FECG measurements from intrauterine growth restricted (IUGR fetuses and to assess whether abdominal FECG parameters can be developed as markers for evaluating the fetal cardiac status in IUGR.Methods: Transabdominal FECG was attempted in 20 controls and 15 IUGR singleton pregnancies at 20+0−33+6 weeks gestation. Standard ECG parameters were compared between the study groups and evaluated for their correlation. Accuracy for the prediction of IUGR by cut off values of the different FECG parameters was also determined.Results: Clear P-QRST complexes were recognized in all cases. In the IUGR fetuses, the QT and QTc intervals were significantly prolonged (p = 0.017 and p = 0.002, respectively. There was no correlation between ECG parameters and Doppler or other indices to predict IUGR. The generation of cut off values for detecting IUGR showed increasing sensitivities but decreasing specificities with the prolongation of ECG parameters.Conclusion: The study of fetal electrocardiophysiology is now feasible through a non-invasive transabdominal route. This study confirms the potential of FECG as a clinical screening tool to aid diagnosis and management of fetuses after key limitations are addressed. In the case of IUGR, both QT and QTc intervals were significantly prolonged and thus validate earlier study findings where both these parameters were found to be markers of diastolic dysfunction. This research is a useful prelude to a test of accuracy and Receiver Operating Characteristics (ROC study.

An intracavitary hyperthermia applicator for targeted heat delivery to the cervix was developed based on a linear array of sectored tubular ultrasound transducers that provides truly 3-D heating control (angular and along the length). A central conduit can incorporate an HDR source for sequential or simultaneous delivery of heat and radiation. Hyperthermia treatment volumes were determined from brachytherapy treatment planning data and used as a basis for biothermal simulations analyzing the effects of device parameters, tissue properties, and catheter materials on heating patterns. Devices were then developed with 1-3 elements at 6.5-8 MHz with 90-180° sectors and a 15-35 mm heating length, housed within a 6-mm diameter water-cooled PET catheter. Directional heating from sectored transducers could extend lateral penetration of therapeutic heating (41°C) >2 cm while maintaining rectum and bladder temperatures within 12 mm below thermal damage thresholds. Imaging artifacts were evaluated with standard CT, cone beam CT, and MR images. MR thermal imaging was used to demonstrate shaping of heating profiles in axial and coronal slices with artifact <2 mm from the device. The impact of the high-Z applicator materials on the HDR dose distribution was assessed using a well-type ionization chamber and was found to be less than 6% attenuation, which can readily be accounted for with treatment planning software. The intrauterine ultrasound device has demonstrated potential for 3-D conformal heating of clinical tumors in the delivery of targeted hyperthermia in conjunction with brachytherapy to the cervix.

Congenital syphilis is rare, but the incidence has increased over the last few years in Alberta. Previous reports of fetal hydrops secondary to syphilis are few and have not demonstrated the application of middle cerebral artery peak systolic velocity (MCA PSV) to monitor for fetal anemia, or reported successful management with intrauterine transfusion. A 17-year-old primigravida at 28 weeks' gestational age with positive syphilis serology and fetal hydrops was treated with high-dose intravenous penicillin. An elevated MCA PSV suggested fetal anemia. Successful intrauterine cordocentesis and transfusion of packed red blood cells led to resolution of fetal hydrops. The fetus delivered spontaneously at 35 weeks' gestation with no clinical signs of congenital syphilis. Syphilitic hydrops may be successfully managed with high dose intravenous penicillin, measurement of MCA PSV, and intrauterine transfusion.
Conclusion: The data presented in this report demonstrate that there was no therapeutic improvement associated with the increased complexity of ZIFT as compared with intrauterine ET after ICSI for the treatment of male-factor infertility. With the advent of improvements in culture techniques in the IVF laboratory, intrauterine ET remains the technique of choice.

the relevance of intrauterine infections is determined by significant peri- and postnatal loss as well as health impairment, which often results in disability and reduced quality of life. Ultrasonography is employed in order to provide a reliable assessment of the functional state of the fetoplacental system secondary to intrauterine fetal infection in the course of pregnancy. Ultrasound imaging is essential in diagnosis of various preclinical complications of pregnancy and detection of abnormalities in the developing fetus. The aim of the study was to perform ultrasonographic assessment of fetoplacental complex in pregnancy complicated by intrauterine infection. the study involved 304 pregnant women who underwent ultrasonographic and bacteriological somatogenic examination. The women were divided into the following groups depending on the presence and nature of the diagnosed infection: Group 1 - 50 patients with normal pregnancy, who were not found to have signs of infection (control group), Group 2 - 50 pregnant women with viral infections (CMV and herpes simplex virus); Group 3 - 50 pregnant women with bacterial infections (chlamydia, ureaplasma, mycoplasma), Group 4 - 154 patients with mixed viral and bacterial infections. Clinical groups with intrauterine infections (IUI) were considered main ones. increased echogenicity of the endothelium of internal and provisional organs was considered to be the main ultrasonographic sign of intrauterine fetal infections as these changes were equally observed in pregnant women of the main group. Main symptoms of viral infections included ventriculomegaly, hypoplasia of the chest, echogenic fibrous inclusions in the papillary muscles and valve flaps, hepatomegaly, placental hypoplasia, oligohydramnios. Dolichocephalic skull, choroid plexus cysts, gastromegaly, placental calcifications, polyhydramnios were more common in bacterial infections. Pregnant women with mixed viral and bacterial infections were found to have those
Full Text Available Intrauterine growth restriction (IUGR infants are thought to have impaired gut function after birth secondary to intrauterine redistribution of the blood flow, due to placental insufficiency, with a consequent reduction of gut perfusion. For this reason, infants complicated by IUGR have been considered at higher risk of feeding intolerance. Postnatal evaluation of splanchnic perfusion, through Doppler of the superior mesenteric artery, and of splanchnic oxygenation, through near infrared spectroscopy measurements, may be useful in evaluating the persistence (or not of the redistribution of blood flow occurred in utero.
Full Text Available Introduction. Intrauterine growth restriction (IUGR is a leading cause of perinatal morbidity and mortality due to placental insufficiency. Currently, one of the new approaches to treating this disease is the injection of nutrients to the fetus through intravascular port-systems (catheters.Objective. To assess the impact of nutrient injections as treatment to fetuses with severe growth retardation.Materials and methods. Pregnant women with IUGR (abdominal circumference (AC < 5th percentile with the absence of diastolic flow in the umbilical artery and a fetal gestational age of less than 30 weeks were randomly divided into two groups. The treatment group included six pregnant women who had an intravascular port-system for the infusion of nutrients (amino acids and glucose in the umbilical vein of the fetus for 14 ± 3 days. The control group consisted of eight patients who received only traditional dynamic monitoring and delivery at the optimum time of pregnancy. Fetal status was assessed using ultrasound equipment Accuvix V20 (Medison, South Korea by examining indicators of biometry and Doppler study of blood flow in utero, umbilical arteries, middle cerebral artery, and ductus venosus with fetal vascular resistance index calculation - pulsatility index (PI. Criteria for blood flow disturbances in the vessels were considered PI values above normal values for their gestational age, which were defined as absence or reverse blood flow in a diastole in the umbilical artery.Results. In a comparative analysis of the two groups, the treatment led to a 44.7% increase in AC of the fetus (121.0 ± 11.5 mm and 219.3 ± 18.3 mm, respectively, p ˂ 0.001. In all cases, the profile of blood flow in the umbilical artery had a positive diastolic component. As a result, there was a 45.3% decrease in PI in the umbilical artery (2.14 ± 0.54 and 1.17 ± 0.15, respectively, p < 0.05. Average fetal weight in the study group was not significantly higher than the

Full Text Available Objectives. Little is known about the utility of simulation-based training in office gynaecology. The objective of this cross-sectional study was to evaluate the self-reported effectiveness and acceptability of the PelvicSim™ (VirtaMed, a high-fidelity mobile simulator, to train clinicians in intrauterine device (IUD insertion. Methods. Clinicians at ambulatory healthcare centres participated in a PelvicSim IUD training programme and completed a self-administered survey. The survey assessed prior experience with IUD insertion, pre- and post-training competency and comfort and opinions regarding the acceptability of the PelvicSim. Results. The 237 participants were primarily female (97.5% nurse practitioners (71.3%. Most had experience inserting the levonorgestrel LNG20 IUD and the copper T380A device, but only 4.1% had ever inserted the LNG14 IUD. For all three devices, participants felt more competent following training, with the most striking change reported for insertion of the LNG14 IUD. The majority of participants reported increased comfort with uterine sounding (57.7%, IUD insertion on a live patient (69.8%, and minimizing patient pain (72.8% following training. Of the respondents, 89.6% reported the PelvicSim IUD insertion activities as “valuable” or “very valuable.” All participants would recommend the PelvicSim for IUD training, and nearly all (97.2% reported that the PelvicSim was a better method to teach IUD insertion than the simple plastic models supplied by IUD manufacturers. Conclusions. These findings support the use of the PelvicSim for IUD training, though whether it is superior to traditional methods and improves patient outcomes requires evaluation.

Full Text Available Perinatal brain injuries and the subsequent development of cerebral palsy are closely associated with intrauterine infections and inflammatory response. Premature prenatal rupture of membranes and premature births are also closely linked to infections and inflammation, and the presence of both infection / inflammation and premature birth together greatly increase the risk for cerebral palsy. Periventricular leukolamacia, a common neonatal brain white matter lesion, is a major risk factor for cerebral palsy. Inflammatory cytokines released during the course of intrauterine infection play an important role in the genesis of brain white matter lesion. Maternal intrauterine infection appears to increase the risk of preterm delivery, which in turn is associated with an increased risk of intraventricular hemorrhage, neonatal white matter damage, and subsequent cerebral palsy. Proinflammatory cytokines IL-1, IL-6 and Tumor necrosis factor-%u03B1 might be the link between prenatal intrauterine infection and neonatal brain damage, and interrupting the proinflammatory cytokine cascade might prevent later disability in those born near the end of the second trimester.

It has been suggested that reading disability (RD), autism spectrum disorder (ASD), and attention-deficit-hyperactivity disorder (ADHD) share a measure of genetic overlap. They also share some epidemiological features, and have all been suspected of multifactorial (genetic and environmental) threshold origins. It has also been hypothesized that ASD, pervasive developmental disorder - not otherwise specified, and ADHD are partially caused by high maternal intrauterine testosterone levels. Here I offer a new method of testing this latter hypothesis on some of these disorders (RD, ADHD, and ASD). All these disorders occur more commonly in males. If the intrauterine testosterone hypothesis was correct, then probands should have a statistically significant excess of brothers among their siblings. Data are adduced here to test this. When treated as individual disorders, the data are significant only in the case of RD. However, the data are highly significant when pooled as RD + ADHD or RD + ADHD + ASD. Taken alone, the data on ASD are not significant. These results suggest that: (1) taxonomically, RD and ADHD are moresimilar to one another than either is to ASD; and (2) probands in the pooled samples have a very highly significant excess of brothers. This result stands in need of explanation. Provisionally, the data may be interpreted as suggesting that RD may be caused by high intrauterine testosterone levels, and confirming the hypothesis that ADHD is partially caused by high intrauterine testosterone.

Our study aimed to explore the relevant risk factors for intrauterine death of fetuses in the third trimester of pregnancy via a retrospective analysis. Then, 98 pregnant women with intrauterine death of fetuses in the third trimester of pregnancy were enrolled, who had undergone the induced labor of dead fetuses in our hospital from January, 2013 to January, 2015. By taking their disease conditions into considerations, methods of induced labor as softening of cervix with dinoprostone suppositories and amniotic infusion of ethacridine or oxytocin were performed, and the timely cesarean section for termination of pregnancy was performed. After the treatment, a detailed medical history was recorded, including their family history, past history and conditions of this pregnancy. Besides, autopsy of dead fetuses and pathological examinations were performed as well as chromosome examinations of the placenta, the umbilical cord and the fetal membrane in an attempt to identify the relevant factors for causes of death, so as to do a good job in the post-natal consultation. The induced labor procedures were successfully performed on all pregnant women, and the investigation of causes of intrauterine death showed that placental factors were responsible for the largest proportion of all causes of intrauterine death in single (28 patients), which was 31.82%, including 13 patients with placenta praevia and 13 with placental abruption. The secondary factors were umbilical cord factors, accounting for 30.68%. Among the factors of pregnant women, gestational hypertension occurred in 7 patients, accounting for 58.33% of factors of pregnant women. While among the causes of intrauterine death in twins, umbilical cord factors were found to be the main causes of death, accounting for 30.00%, followed by placental factors and factors of pregnant women, which accounted for 20.00%, respectively. Placenta factors, umbilical cord factors and factors of pregnant women were the main causes of
Full Text Available Abstract Introduction The Mirena intrauterine system has been licensed as a contraceptive in the United Kingdom since May 1995. The use of an intrauterine system as a primary method of contraception among women has been slowly increasing over the last few years and they now account for about 3% of contraceptive use in England. The Mirena intrauterine system now also has a license for the management of idiopathic menorrhagia. Women may be informed that the rate of uterine perforation associated with intrauterine contraceptive use is low (0-2.3 per 1000 insertions. The rate of perforation reported with the Mirena intrauterine system in a large observational cohort study was 0.9 per 1000 insertions. Case presentation In this case report, the diagnosis of an intraperitoneal Mirena intrauterine system was noted nearly four years after its insertion, despite the patient having had a vaginal hysterectomy and admissions to hospital in the interim with complaints of abdominal pain. Conclusion This case report demonstrates clearly that whenever there is a question of a intrauterine system having fallen out following an ultrasound scan report showing an empty uterus, clinicians should also perform an abdominal X-ray.
Full Text Available OBJECTIVES: Recent studies have shown that telomere length was significantly reduced in placentas collected at delivery from pregnancies complicated by intrauterine growth restriction secondary to placental insufficiency. Placental telomere length measurement during ongoing pregnancies complicated by intrauterine growth restriction has never been reported. This was the main objective of our study. METHODS: In our center, late chorionic villus samplings were performed between 18 and 37 weeks of amenorrhea in 24 subjects with severe intrauterine growth restriction (cases and in 28 subjects with other indications for prenatal diagnosis (controls. Placental insufficiency was assessed by histo-pathological examination. Relative measurement of telomere length was carried out prospectively by quantitative Fluorescent In Situ Hybridization using fluorescent Peptide Nucleic Acid probes on interphase nuclei obtained from long-term cultured villi and with an automated epifluorescent microscope. A quantitative Polymerase Chain Reaction technique was performed to confirm the quantitative Fluorescent In Situ Hybridization results. The number of copies of gene loci encoding the RNA template (hTERC and the catalytic subunit (hTERT of the enzyme complex telomerase were also estimated in these placentas by Fluorescent In Situ Hybridization. RESULTS: Mean fluorescence intensity of telomere probes estimated by quantitative Fluorescent In Situ Hybridization was significantly less for cases compared to controls (p<0.001. This result indicated that mean telomere length was significantly reduced in placentas during pregnancies complicated by intrauterine growth restriction. Reduced telomere length was confirmed by the quantitative Polymerase Chain Reaction technique. No copy number variation of the hTERC and hTERT loci was noticed for cases, or for controls. CONCLUSION: This study clearly demonstrates a reduction of placental telomere length in ongoing pregnancies

The aim of this study was to explore the factors that influence the outcome of intrauterine human chorionic gonadotropin (hCG) infusion at the time of embryo transfer (ET), in particular, the effect of hCG infusions on fresh and frozen embryo transfers (FETs) and whether prior recurrent implantation failure (RIF) impacts upon outcomes. This was a case-control study based on a standardized database from a multi-site in vitro fertilization clinic. The analysis contains 458 cases and 749 matched controls, with an intervention group of those given intrauterine hCG prior to ET and a control group of patients receiving no hCG infusion. Outcomes were defined as clinical pregnancy and live birth rates. Two analyses were performed. The first separated FETs (cases n = 224, controls n = 325) and fresh ETs (cases n = 234, controls n = 424), with outcomes calculated in each group. The second analysis divided patients into those with RIF (cases n = 149, controls n = 200) and those without (cases n = 309, controls n = 549). Results in fresh ETs demonstrated a 5.8% reduction (adjusted odds ratio (AOR) = 0.60, p = 0.041) in clinical pregnancy rates with the use of intrauterine hCG. In those without defined RIF, clinical pregnancy rates were reduced by 8.1% (AOR = 0.61, p = 0.023) and live birth rates by 7.2% (AOR = 0.56, p = 0.32) with intrauterine hCG use. There were no significant differences in outcomes in FETs and in the RIF cohort. Intrauterine hCG at the time of ET not only seems to have no benefit, but rather a negative effect in fresh ETs and those without RIF.

In the 1970s a new approach to the delivery of hormonal contraception was researched and developed. It was suggested that the addition of a progestogen to a non-medicated contraceptive device improved its contraceptive action. An advantage of these hormonally impregnated intrauterine systems (IUS) is that they are relatively maintenance free, with users having to consciously discontinue using them to become pregnant rather than taking a proactive daily decision to avoid conception. To assess the contraceptive efficacy, tolerability and acceptability of hormonally impregnated intrauterine systems (IUSs) in comparison to other reversible contraceptive methods. Literature was identified through database searches, reference lists and individuals/organisations working in the field. Searches covered the period from 1972 to November 2003. All randomised controlled trials comparing IUSs with other forms of reversible contraceptives and reporting on pre-determined outcomes in women of reproductive years. The primary outcomes were pregnancy due to method/user failure and continuation rate. The quality assessment of studies and data extraction were completed independently by two blinded reviewers. A quality checklist was designed to identify general methodological and contraceptive specific factors which could bias results. Events per women months and single decrement life table rates were extracted where possible for pregnancy, continuation, adverse events and reasons for discontinuation. Events per total number of women at follow up were collected for hormonal side effects and menstrual disturbance. When appropriate, data were pooled at the same points of follow up to calculate rate ratios in order to determine the relative effectiveness of one method compared to another. For the single decrement life table rates, the rate differences were pooled to determine the absolute difference in effectiveness of one method compared to another. Interventions were only combined if the

Considering the hypothetical concern of retrograde tumor spread to the peritoneal cavity by insertion of an intrauterine manipulator, we examined the correlation between the timing of manipulator insertion and the results of pelvic cytology during total laparoscopic hysterectomy (TLH) in endometrial cancer. Case-control study (Canadian Task Force classification II-2). University-based hospitals. Stage I to IV endometrial cancer patients who underwent TLH in which an intrauterine manipulator was used. Medical records were reviewed for patient demographics, surgical details, and tumor characteristics. Archived medical record review. A total of 333 patients was identified. Cases were divided into those with intrauterine manipulator insertion after pelvic cytology sampling (Group 1, n = 103) and those with intrauterine manipulator insertion before pelvic cytology sampling (Group 2, n = 230). Types of intrauterine manipulator were similar across the 2 groups (p = .77). There was no statistical difference in the results of pelvic cytology between the 2 groups: Group 1 versus 2, atypical cells 2.9% versus 4.8% and malignant cells 5.8% versus 9.6% (p = .36). Uterine perforation related to intrauterine manipulator insertion was seen in 1.0% and .4% of each group (p = .52). In a multivariate analysis controlling for demographics and tumor characteristics, advanced-stage disease remained an independent risk factor associated with increased risk of atypical and malignant cells (adjusted odds ratio, 10.3; 95% confidence interval, 4.44-23.8; p cytology.

Full Text Available Epidemiologic studies have demonstrated an association between intrauterine growth retardation and a greater risk of chronic disease, including coronary heart disease, hypertension, stroke, and type 2 diabetes in adulthood. An adverse intrauterine environment may affect both growth and development of the organism, permanently programming endocrine and metabolic functions. One of the mechanisms of programming is the epigenetic modification of gene promoters involved in the control of key metabolic pathways. The aim of this review is to provide an overview of the experimental evidence showing the effects of early exposure to suboptimal environment on epigenome. The knowledge of the epigenetic markers of programming may allow the identification of susceptible individuals and the design of targeted prevention strategies.

Emission analysis with the use of induced plasma was employed to measure the content of 9 bioelements (potassium, sodium, calcium, magnesium, phosphorus, iron, copper, zinc and selenium) in the blood serum of 82 neonates with a history of chronic intrauterine hypoxia and in 19 normal children at birth and in the course of early adaptation. It has been shown that the content of bioelements in the blood of normal neonates was marked by a number of characteristic features reflecting to a considerable degree the processes of metabolic adaptation of the children to the intrauterine life. The neonates with a history of hypoxia demonstrated the unbalance of bioelements most pronounced by day 3 of life. The treatment instituted did not make the content of bioelements in the neonates' blood return to normal.

Background and aim: Infantile colic is characterised by crying bouts in a healthy infant during the first months. Smoking in pregnancy and low birth weight (BW) have been previously identified as risk factors for infantile colic. Nicotine acts as a neurotransmitter and is known to affect...... the intrauterine central nervous system development, while low BW and premature birth have both been related to adverse neurodevelopmental outcomes. We investigated the association between intrauterine nicotine exposure, BW, gestational age (GA) and infantile colic in a large cohort study. Materials and methods......: We used data from the Danish National Birth Cohort. The study on nicotine exposure included 63,128 infants and the study on BW and GA included 62, 785 infants with complete data. Infantile colic was defined according to the modified Wessel’s criteria based on maternal interview 6 months postpartum...
Full Text Available Background: This study was aimed to assess the effect of endometrial movements on pregnancy achievement in intrauterine insemination (IUI cycles. Materials and Methods: The population of this observational study was composed of unexplained infertility couples undergoing first-time IUI with clomiphene citrate between September 2010 and October 2011. Not only endometrial movements, but also thickness, volume, pattern, and echogenic change of endometrium were analyzed prospectively in prediction of pregnancy. Results: The total number of 241 cycles of IUI with 49 intrauterine pregnancies (20.3% was analyzed. Pregnancy was not related to endometrial thickness and endometrial volume, but significantly related to endometrial movements associated with the number of contraction, strong movement, cervicofundal direction, and hyperechoic change (p<0.05. Pregnant group showed higher cervicofundal movement rate (89.8 vs. 75.5%. Conclusion: For IUI cycles stimulated by clomiphene citrate in unexplained infertility women, endometrial movements on the day of IUI could be a predictor of pregnancy.

To report a rare case of maternal hyperthyroidism after intrauterine insemination due to hypertrophic action of hCG. A 36-year-old woman after successful intrauterine insemination and triplet pregnancy, developed hyperthyroidism with resistance to medical treatment. All signs of hyperthyroidism resolved and the results of thyroid function tests returned to normal without any medication after embryo meiosis. De novo maternal hyperthyroidism may develop during pregnancy as a result of pathological stimulation of the thyroid gland from the high levels of hCG hormone that can be seen in multiple pregnancies. The risk of hyperthyroidism is related to the number of fetuses. Reversibility of symptomatology can be seen after fetal reduction of multiple pregnancies.

Congenital cutaneous candidiasis is a very rare disease with less than 100 cases published in the medical literature. Neonates having this disease present with systemic skin lesions caused by intrauterine Candida infections. We present a case of threatened premature delivery due to Candida chorioamnionitis, which caused both maternal postpartum endometritis and neonatal congenital cutaneous candidiasis. A 34-year-old woman who was admitted for fetal membrane bulging at 20 weeks of gestation underwent McDonald cervical cerclage. We diagnosed threatened premature delivery due to intrauterine infection; therefore, we terminated the gestation by cesarean section at 24 weeks of gestation. Fungi-like yeast was detected in infantile gastric juice. Histopathological findings of the placenta revealed that Candida albicans mycelium invaded the placenta, chorioamniotic membrane and umbilical cord. © 2012 The Authors.

The incidence of gestational diabetes is increasing worldwide, exposing large numbers of infants to hyperglycaemia whilst in utero. This exposure may have a long-term negative impact on the cardiovascular health of the offspring. Novel methods to assess cardiovascular status in the neonatal period are now available—including measuring arterial intima-media thickness and retinal photography. These measures will allow researchers to assess the relative impact of intrauterine exposures, distinguishing these from genetic or postnatal environmental factors. Understanding the long-term impact of the intrauterine environment should allow the development of more effective health policy and interventions to decrease the future burden of cardiovascular disease. Initiating disease prevention aimed at the developing fetus during the antenatal period may optimise community health outcomes. PMID:23133443

The relationship between somatic growth and neurocognitive outcome was studied in a cohort of 136 children with intrauterine growth retardation. The children were followed up from birth to 9 to 10 years of age by annual measurements of growth parameters, neurodevelopmental evaluations, and IQ. The rate of catch-up for height between 1 and 2 years of age was significantly higher than the catch-up for weight (P cognitive outcome at 9 to 10 years correlated with head circumference at all ages. The neurodevelopmental outcome at 9 to 10 years correlated with weight at all ages. Correlation with head circumference was more significant with IQ, while with weight it was stronger with the neurodevelopmental score. Height at 1 year was a significant predictor for IQ and neurodevelopmental outcome at 9 to 10 years. These findings are of distinct importance for prediction of subsequent neurodevelopmental outcome in children with intrauterine growth retardation.

To determine whether intrauterine myelomeningocele repair performed at between 20 and 28 weeks gestation improves lower extremity function (LEF). Thirty-seven consecutive patients who had undergone intrauterine repair of their myelomeningocele at Vanderbilt University Medical Center had their lower extremity function and radiographic level (first defective vertebral level) compared to these same parameters in 40 controls who had undergone traditional postgestational repair of their myelomeningocele at the Children's Hospital in Birmingham, Ala., USA. Of all 77 patients (controls and study group), 13 had a LEF that matched their radiographic level, 27 had a LEF that was rostral to their radiographic level, and 37 had a LEF that was caudal to their radiographic level. Further stratification revealed that for the intrauterine repaired myelomeningoceles, 11% had no difference between LEF and radiographic level, 43% had a LEF that was rostral to their radiographic level, and 46% had a LEF that was caudal to their radiographic level. For those closed in a traditional manner, LEF matched their radiographic level, was rostral to their radiographic level, and was caudal to their radiographic level in 22.5%, 27.5%, and 50% respectively. However, the overall mean differences between institutions produced a p-value of 0.2026 (paired t-test). Although the current timing of intrauterine myelomeningocele repair has been found to lessen the degree of herniation of the rhombencephalon and reduce the incidence of shunt-dependent hydrocephalus, it does not statistically improve LEF. Parents should be advised of these findings prior to surgical intervention so as to focus their expectations. Copyright 2003 S. Karger AG, Basel

To identify timing-specified risk factors for stillbirth, in order to help physicians to reduce preventable factors and stillbirths, and improve general outcomes of pregnancy. A retrospective analysis was performed of births registered in our hospital, a medical center in Taiwan, between September 1, 1999 and December 31, 2011. We collected basic characteristics from the medical records, including maternal and fetal conditions. All stillbirths were divided into two groups according to gestational age: the second trimester group and the third trimester group. Comparisons were made between these groups. There were a total of 12,290 births and 121 stillbirths during our study period. The 121 stillbirths were divided into two groups: 67/121 (55.4%) were in the second trimester group and 54/121 (44.6%) were in the third trimester group. The overall incidence for intrauterine fetal demise was 0.98% (121/12,290). The increased risks in the third trimester stillbirths, as compared with the second trimester group, were significantly associated with males born, increased maternal body mass index (BMI) at delivery, habitual cigarette smoking, previous history of intrauterine fetal demise, and diabetic or hypertensive pregnancies. Unexplained causes (29.85%) were the most common causes of second trimester intrauterine fetal demise and the most common cause of third trimester intrauterine fetal demise was umbilical cord pathology (33.33%). Management of any pregnant patient remains a challenge. Identifying upstream and cost-effective solutions will improve these pregnancy outcomes. Copyright © 2013. Published by Elsevier B.V.

There is no clear consensus on optimal management of fetuses affected by familial hypertrophic cardiomyopathy (HCM). Intrauterine treatment of the condition has not been attempted in any standardized fashion. We report the case of a fetus treated by maternal propranolol during the third trimester after septal hypertrophy and diastolic dysfunction was diagnosed on fetal echocardiogram. The pregnancy went successfully to term, and fetal septal hypertrophy was noted to improve prior to delivery.

We aimed to investigate the role of peripheral blood mononuclear cell transportation from mother to baby in hepatitis B virus (HBV) intrauterine infection. Thirty HBsAg-positive pregnant women in the second trimester and their aborted fetuses were included in this study. Enzyme-linked-immunosorbent-assay was utilized to detect HBsAg in the peripheral blood of pregnant women and the femoral vein blood of their aborted fetuses. HBV-DNA in serum and peripheral blood mononuclear cells (PBMC) and GSTM1 alleles of pregnant women and their aborted fetuses were detected by nested polymerase chain reaction (PCR) and seminested PCR, respectively. We also examined the location of placenta HBsAg and HBcAb using immunohistochemical staining. The expression of placenta HBV-DNA was detected by in situ hybridization. For the 30 aborted fetuses, the HBV intrauterine infection rate was 43.33%. The HBV-positive rates of HBsAg in peripheral blood, serum, and PBMC were 10% (3/30), 23.33% (7/30), and 33.33% (10/30), respectively. Maternal-fetal PBMC transport was significantly positively correlated with fetal PBMC HBV-DNA (P = 0.004). Meanwhile, the rates of HBV infection gradually decreased from the maternal side to the fetus side of placenta (decidual cells > trophoblastic cells > villous mesenchymal cells > villous capillary endothelial cells). However, no significant correlation between placenta HBV infection and HBV intrauterine infection was observed (P = 0.410). HBV intrauterine infection was primarily due to peripheral blood mononuclear cell maternal-fetal transportation in the second trimester in pregnant women.

Fetal and neonatal haemolytic diseases result from maternal allo-immunisation to fetal antigens. Maternal antibodies cross the placenta causing red cell haemolysis, resulting in fetal anaemia and, in severe cases, hydrops and perinatal death. Intravascular intrauterine blood transfusion (IUT) has markedly reduced perinatal mortality and is now a standard procedure. IUT is considered to be a safe procedure with fetal loss rate reported to be less than 5% and no reported increase in the rate of...

Full Text Available There have been indications that intrauterine and early extrauterine growth can influence childhood mental and motor function. The objective of the present study was to evaluate the influence of intrauterine growth restriction and early extrauterine head growth on the neurodevelopmental outcome of monozygotic twins. Thirty-six monozygous twin pairs were evaluated at the corrected age of 12 to 42 months. Intrauterine growth restriction was quantified using the fetal growth ratio. The effects of birth weight ratio, head circumference at birth and current head circumference on mental and motor outcomes were estimated using mixed-effect linear regression models. Separate estimates of the between (interpair and within (intrapair effects of each measure on development were thus obtained. Neurodevelopment was assessed with the Bayley Scales of Infant Development, 2nd edition, by a psychologist blind to the exposure. A standardized neurological examination was performed by a neuropediatrician who was unaware of the exposures under investigation. After adjustment, birth weight ratio and head circumference at birth were not associated with motor or mental outcomes. Current head circumference was associated with mental but not with motor outcomes. Only the intrapair twin effect was significant. An increase of 1 cm in current head circumference of one twin compared with the other was associated with 3.2 points higher in Mental Developmental Index (95%CI = 1.06-5.32; P < 0.03. Thus, no effect of intrauterine growth was found on cognition and only postnatal head growth was associated with cognition. This effect was not shared by the co-twin.

Full Text Available Preterm birth is a major risk factor for neurodevelopmental delays and disorders. This study aimed to identify genomic biomarkers of intrauterine inflammation in umbilical cord tissue in preterm neonates that predict cognitive impairment at 10 years of age.Genome-wide messenger RNA (mRNA levels from umbilical cord tissue were obtained from 43 neonates born before 28 weeks of gestation. Genes that were differentially expressed across four indicators of intrauterine inflammation were identified and their functions examined. Exact logistic regression was used to test whether expression levels in umbilical cord tissue predicted neurocognitive function at 10 years of age.Placental indicators of inflammation were associated with changes in the mRNA expression of 445 genes in umbilical cord tissue. Transcripts with decreased expression showed significant enrichment for biological signaling processes related to neuronal development and growth. The altered expression of six genes was found to predict neurocognitive impairment when children were 10 years old These genes include two that encode for proteins involved in neuronal development.Prenatal intrauterine inflammation is associated with altered gene expression in umbilical cord tissue. A set of six of the differentially expressed genes predict cognitive impairment later in life, suggesting that the fetal environment is associated with significant adverse effects on neurodevelopment that persist into later childhood.

A complex of various malformations in newborns was observed to an increased extent in sheep farms in the 2011/2012 lambing season. An intrauterine Schmallenberg virus (SBV) infection was identified as the cause of these malformations. To date, a detailed pathological description of the deformity complex has only been given for bovine and ovine newborns.The aim of this study was therefore to provide a description of pathologic-anatomical congenital malformations in goat kids caused by intrauterine SBV infection. To this end, pathologic-anatomical and molecular biological investigations by PCR were carried out on 37 goat kids and 457 lambs from 238 sheep and goat farms in order to carry out an interspecies comparison. Of the 37 goat kids dissected, it was possible to identify a SBV infection in twelve animals (32.4%) by RT-PCR. In nine animals (24.3%) displaying pathological-anatomical malformations SBV could not be detected by PCR. The following malformations were observed: athrogryposis, deformation of spinal column, torticollis, asymmetry of the skull, brachygnathia inferior, cerebellar hypoplasia, cerebellar aplasia and internal hydrocephalus. Arthogryposis was the most common malformation, both in animals with positive PCR results and those with negative PCR results. This study documents congenital malformations caused by an intrauterine SBV infection for the first time on a large number of newborn goats.

Intra-uterine growth retardation (IUGR) represents one of the major problems in perinatal medicine. IUGR is one of main causes of perinatal mortality and morbidity. A huge number and variety of established and possible causes of IUGR have been described. There are currently no data about effective treatment of this fetal condition. IUGR has been described to be strictly involved in fetal programming. Fetal programming is the general idea, which tells us how during development of the embryo and fetus significant physiological parameters can be shaped by environmental events. A link between the intra-uterine growth retardation and the risk of developing type 2 diabetes, obesity and cardiovascular disease postnatally has been well documented. The aim of this paper is to present an overview of the current knowledge of IUGR effects on development of hypertension and cardiovascular diseases, impact on insulin secretion and resistance, diabetes mellitus and metabolic syndrome. The influence of intrauterine growth retardation on predisposition to obesity and adipose dysfunction was also described.

To determine the incidence, stressors and perinatal outcomes of intrauterine growth retardation in the hospitals of the Ministry of Health of Peru. Cross-sectional, analytical, case-control study of 9777 infants with intrauterine growth retardation (IUGR) in 29 hospitals of the Ministry of Health of Peru in 2010. The Peruvian intrauterine growth curve was used for the diagnosis of IUGR. IUGR newborns (cases) and newborns appropriate for gestational age (controls) were compared using the odds ratio (OR) with a confidence interval of 95%. The incidence of IUGR was 10.1%. The incidence by region was: 8.1% Coast, 11.8% Selva and Sierra 14.6%. The frequency of stress factors of IUGR were: nutrition (92%), psychological (84.8%), social (53%), anatomical (63.6%), toxic/environmental (52.9%), vascular (29,8%), infection (14.1%) and metabolic (0.3%). The newborn with IUGR had higher perinatal morbidity (OR=2,1) and mortality (OR=3.5). The healthy fetus is the result of a balance between stress factors and the adaptive response of the mother and fetus. When the response of physiological adaptation is overcome by stress factors, IUGR occurs.The political, psychological, nutritional and medical intervention before 12 weeks of gestation has the potential to change the harmful effects of all human stress factors that affect fetal growth.

Full Text Available Background: N-acetyl cysteine (NAC was proposed as an adjuvant to clomiphene citratefor ovulation induction in patients with polycystic ovary syndrome (PCOS without clomiphene citrate resistance. Objective: To evaluate the effect of NAC on pregnancy rate in PCOS patients who were candidates for intrauterine insemination. Materials and Methods: In this randomized clinical trial 97 PCOS women aged 18-38 years were enrolled in two groups, randomly. For the case group (n=49, NAC (1.2 gr+ clomiphene citrate (100 mg + letrozole (5mg were prescribed Daily from the third day of menstruation cycle for five days. The control group (n=48 had the same drug regimen without NAC. In order to follicular development, GONALF was injected on days of 7-11 menstrual cycles in all participants. When the follicle size was 18mm or more, HCG (10000 IU was injected intramuscular and the intrauterine insemination was performed after 34-36 hr. Results: There were not significant differences between study groups regarding mean endometrial thickness (p=0.14, mean number of mature follicles (p=0.20 and the pregnancy rate (p=0.09. Conclusion: NAC is ineffective in inducing or augmenting ovulation in PCOS patients who were candidates for intrauterine insemination and cannot be recommended as an adjuvant to CC in such patients.

Fetal intrauterine growth restriction generates chronic hypoxia due to placental insufficiency. Despite the hemodynamic process of blood flow, redistributions are taking place in key organs such as the fetal brain during intrauterine growth restriction, in order to maintain oxygen and nutrients supply. The risk of short- and long-term neurological effects are still present in hypoxic offspring. Most studies previously reported the effect of hypoxia on the levels of a single neurotransmitter, making it difficult to have a better understanding of the relationship among neurotransmitter levels and the defects reported in products that suffer intrauterine growth restriction, such as motor development, coordination and execution of movement, and the learning-memory process. The aim of this study was to evaluate the levels of gamma-aminobutyric acid, glutamate, dopamine and serotonin in three structures of the brain related to the above-mentioned function such as the cerebral cortex, the striatum, and the hippocampus in the chronic hypoxic newborn rabbit model. Our results showed a significant increase in glutamate and dopamine levels in all studied brain structures and a significant decrease in gamma-aminobutyric acid levels but only in the striatum, suggesting that the imbalance on the levels of several neurotransmitters could be involved in new born brain damage due to perinatal hypoxia.

Fetal growth is a complex process that depends on the genotype and epigenotype of the fetus, maternal nutrition, the availability of nutrients and oxygen to the fetus, intrauterine insults, and a variety of growth factors and proteins of maternal and fetal/placental origin. In the fetus, growth hormone (GH) plays little or no role in regulating fetal growth, and insulin-like growth factors (IGFs) control growth directly independent of fetal GH secretion. Placental growth hormone (PGH) is the prime regulator of maternal serum IGF-1 during pregnancy. Total as well as free PGH and IGFs are significantly lower in pregnancies with intrauterine growth retardation (IUGR). The GH/IGF axis is significantly affected by intrauterine growth retardation and some of these alterations may lead to permanent pathological programming of the IGF axis. Alterations in the IGF axis may play a role in the future occurrence of insulin resistance and hypertension. In this review we focus on the regulation of fetal growth and the role of fetal programming in the late consequences of a poor fetal environment reflected in IUGR.

After intrauterine growth retardation, many minor neurodevelopmental disorders may occur, especially in the motor skills domain, language and speech development, and cognitive functions. The assessment of language development and impact of postnatal head growth in preschool children born with asymmetrical intrauterine growth retardation. Examinees were born at term with birth weight below the 10th percentile for gestational age, parity and gender. Mean age at the time of study was six years and four months. The control group was matched according to chronological and gestational age, gender and maternal education with mean age six years and five months. There were 50 children with intrauterine growth retardation and 50 controls, 28 girls and 22 boys in each group. For the assessment of language development Reynell Developmental Language Scale, the Naming test and Mottier test were performed. There were statistically significant differences (p development which is evident in preschool years. Slow postnatal head growth is correlated with poorer language outcome. Neonatal complications were negatively correlated with language comprehension and total expressive language. Copyright © 2011 European Paediatric Neurology Society. Published by Elsevier Ltd.

Full Text Available BACKGROUND: Different factors contribute to the onset of labor at term. In animal models onset of labor is characterized by an inflammatory response. The role of intrauterine inflammation, although implicated in preterm birth, is not yet established in human term labor. We hypothesized that intrauterine inflammation at term is associated with spontaneous onset of labor. METHODS/RESULTS: In two large urban hospitals in the Netherlands, a cross-sectional study of spontaneous onset term vaginal deliveries and elective caesarean sections (CS, without signs of labor, was carried out. Placentas and amniotic fluid samples were collected during labor and/or at delivery. Histological signs of placenta inflammation were determined. Amniotic fluid proinflammatory cytokine concentrations were measured using ELISA. A total of 375 women were included. In term vaginal deliveries, more signs of intrauterine inflammation were found than in elective CS: the prevalence of chorioamnionitis was higher (18 vs 4%, p = 0.02 and amniotic fluid concentration of IL-6 was higher (3.1 vs 0.37 ng/mL, p<0.001. Similar results were obtained for IL-8 (10.93 vs 0.96 ng/mL, p<0.001 and percentage of detectable TNF-alpha (50 vs 4%, p<0.001. CONCLUSIONS: This large cross-sectional study shows that spontaneous term delivery is characterized by histopathological signs of placenta inflammation and increased amniotic fluid proinflammatory cytokines.

Twin-twin transfusion syndrome (TTTS) is a severe complication of monozygotic (identical) twin fetuses sharing one single (monochorionic) placenta. TTTS is caused by a net inter-twin transfusion of blood through placental anastomoses, from one twin (the donor) to the other (the recipient), which link the two feto-placental circulations. Currently, the only reliable method to measure the net inter-twin transfusion clinically is when incomplete laser therapy of TTTS occurs and one of the twins becomes anemic and requires an intra-uterine transfusion of adult red blood cells. Then, differences between adult hemoglobin concentrations measured during the transfusion and at birth relate not only to the net inter-twin transfusion but also to the finite lifetime of the adult red blood cells. We have analyzed this situation, derived the differential equations of adult hemoglobin in the donor and recipient twins, given the solutions and given expressions relating the net inter-twin flow with clinically measured parameters. We have included single and multiple intra-uterine transfusions. In conclusion, because incomplete laser therapy occurs frequently, and some cases require an intra-uterine transfusion, this method may allow collecting a wealth of net inter-twin flow data from clinicians involved in laser therapy of TTTS. To aid to the widespread use of this method, we have presented the equations as clearly as possible in tables for easy use by others. (note)

To evaluate the feasibility and impact of levonorgestrel intrauterine system (LNG-IUS) on treatment failure after endometrial ablation (EA) in women with heavy menstrual bleeding (HMB) and dysmenorrhea at 4 years. Cohort study (Canadian Task Force II-2). An academic institution in the upper Midwest. All women with HMB and dysmenorrhea who underwent EA with combined placement of LNG-IUS (EA/LNG-IUS cohort, 23 women) after 2005 and an historic reference group from women who had EA alone (EA cohort, 65 women) from 1998 through the end of 2005. Radiofrequency EA, thermal balloon ablation, and LNG-IUS. The primary outcome was treatment failure defined as persistent pain, bleeding, and hysterectomy after EA at 4 years. The combined treatment failure outcome was documented in 2 patients (8.7%) in the EA/LNG-IUS group and 19 patients (29.2%) in the EA group with an unadjusted OR of .23 (95% CI, .05-1.08). After adjusting for known risk factors of failure, the adjusted OR was .19 (95% CI, .26-.88). None of the women who underwent EA/LNG-IUS had hysterectomy for treatment failure compared with 16 (24%) in the EA group (p = .009); postablation pelvic pain was documented in 1 woman (4.3%) in the EA/LNG-IUS group compared with 8 women (12.3%) in the EA group (p = .24). One woman in the EA/LNG-IUS group (4.3%) presented with persistent bleeding compared with 15 (23.1%) in the EA group (p = .059). Office removal of the intrauterine device was performed in 4 women with no complications. LNG-IUS insertion at the time of EA is feasible and can provide added benefit after EA in women with dysmenorrhea and HMB. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.
Full Text Available OBJECTIVE: To undertake an economic evaluation alongside the largest randomised controlled trial comparing Levonorgestrel-releasing intrauterine device ('LNG-IUS' and usual medical treatment for women with menorrhagia in primary care; and compare the cost-effectiveness findings using two alternative measures of quality of life. METHODS: 571 women with menorrhagia from 63 UK centres were randomised between February 2005 and July 2009. Women were randomised to having a LNG-IUS fitted, or usual medical treatment, after discussing with their general practitioner their contraceptive needs or desire to avoid hormonal treatment. The treatment was specified prior to randomisation. For the economic evaluation we developed a state transition (Markov model with a 24 month follow-up. The model structure was informed by the trial women's pathway and clinical experts. The economic evaluation adopted a UK National Health Service perspective and was based on an outcome of incremental cost per Quality Adjusted Life Year (QALY estimated using both EQ-5D and SF-6D. RESULTS: Using EQ-5D, LNG-IUS was the most cost-effective treatment for menorrhagia. LNG-IUS costs £100 more than usual medical treatment but generated 0.07 more QALYs. The incremental cost-effectiveness ratio for LNG-IUS compared to usual medical treatment was £1600 per additional QALY. Using SF-6D, usual medical treatment was the most cost-effective treatment. Usual medical treatment was both less costly (£100 and generated 0.002 more QALYs. CONCLUSION: Impact on quality of life is the primary indicator of treatment success in menorrhagia. However, the most cost-effective treatment differs depending on the quality of life measure used to estimate the QALY. Under UK guidelines LNG-IUS would be the recommended treatment for menorrhagia. This study demonstrates that the appropriate valuation of outcomes in menorrhagia is crucial.

Full Text Available Intrauterine growth restriction is associated with increased risk for adult metabolic syndrome and cardiovascular disease, which seems to be related to altered food preferences in these individuals later in life. In this study, we sought to understand whether intrauterine growth leads to fetal programming of the hedonic responses to sweet. Sixteen 1-day-old preterm infants received 24% sucrose solution or water and the taste reactivity was filmed and analyzed. Spearman correlation demonstrated a positive correlation between fetal growth and the hedonic response to the sweet solution in the first 15 seconds after the offer (r=0.864, P=0.001, without correlation when the solution given is water (r=0.314, P=0.455. In fact, the more intense the intrauterine growth restriction, the lower the frequency of the hedonic response observed. IUGR is strongly correlated with the hedonic response to a sweet solution in the first day of life in preterm infants. This is the first evidence in humans to demonstrate that the hedonic response to sweet taste is programmed very early during the fetal life by the degree of intrauterine growth. The altered hedonic response at birth and subsequent differential food preference may contribute to the increased risk of obesity and related disorders in adulthood in intrauterine growth-restricted individuals.
Full Text Available Epidemiological, clinical, physiological, cellular, and molecular evidence suggests that the origins of obesity and metabolic dysfunction can be traced back to intrauterine life and supports an important role for maternal nutrition prior to and during gestation in fetal programming. The elucidation of underlying mechanisms is an area of interest and intense investigation. In this perspectives paper we propose that in addition to maternal nutrition-related processes it may be important to concurrently consider the potential role of intrauterine stress and stress biology. We frame our arguments in the larger context of an evolutionary-developmental perspective that supports roles for both nutrition and stress as key environmental conditions driving natural selection and developmental plasticity. We suggest that intrauterine stress exposure may interact with the nutritional milieu, and that stress biology may represent an underlying mechanism mediating the effects of diverse intrauterine perturbations, including but not limited to maternal nutritional insults (undernutrition and overnutrition, on brain and peripheral targets of programming of body composition, energy balance homeostasis, and metabolic function. We discuss putative maternal-placental-fetal endocrine and immune/inflammatory candidate mechanisms that may underlie the long-term effects of intrauterine stress. We conclude with a commentary of the implications for future research and clinical practice.

Approximately 21 days after an abortion, ovulation occurs in 50 % of women. Installation of an IUD directly after induced or spontaneous abortion offers immediate contraceptive protection. The purpose of the present study was to weigh up contraceptive safety and adverse reactions of IUD inserted directly after first-trimester abortion under general or paracervical anesthesia as against the fitting of IUD in the days of the next menstrual cycle without anesthesia. During the period May 1987 to October 2010, 73 women (Group A) underwent an immediate post-abortion insertion IUD after a first-trimester spontaneous or induced abortion under general or local paracervical anesthesia and 69 participants (Group B) received IUD during the next menstrual cycle without anesthesia. Questionnaires were completed by all the women of the study with respect to the effects of IUD. The women were examined every 3 months for 1 year after the fitting of the IUD in the out-patient department of the University Obstetrics Gynecological Department of Alexandroupolis, Democritus University of Thrace, Greece. The demographic characteristics of the women of the two groups were similar. The age of the women ranged between 19 and 44 years, while 61.98 % were women with one or two children and 38.02 % were women with three or more children. During the first menstrual cycles, with the exception of vaginal hemorrhages (5 %) and adnexitis (1 %), no serious adverse reactions were noted. During the transvaginal ultrasonography checks in both groups, no observation was made of any dislocation of the IUD, except for two cases in the subgroup of those women with paracervical anesthesia and one case in the women of Group B. As concerns the questionnaire with regard to the women's subjective evaluation of IUD, satisfactory answers were given. There were no differences between the two groups either with respect to the security of the supplied contraceptive methods or to the development of side effects.

66 women were examined to determine the copper concentration in their serum and endometrium after prolonged use of an IUD (Lippes Loop, Hall Ring, Birnberg, Saf-T-Coil, Tatum, and Copper 7). A control of 16 nonusers was included. The level of copper was found by atomic absorption spectrophotometry. In the control group, the copper concentration in the serum was a mean of 100 gamma/100 cc of serum and in the endometrial tissue, a mean of 251 gamma/100 gm/wet tissue. In women using IUDs with no copper, the concentration in the serum was in the normal range, but in endometrial tissue it was between 457-586 gamma/100 gm. Similar findings came with the examination of women using IUDs containing copper. The high concentration of copper in inflamed endometrial tissue led to the hypothesis that such a condition, ith accompanying hyperenemia and hyperkinesia of the uterus and tubes are the principle factors for the contraceptive action of IUDs.
.... This efficacy is not affected by age or parity. The safety of IUDs is well studied, and the risks of pelvic inflammatory disease, perforation, expulsion, and ectopic pregnancy are all of very low incidence...

To determine the effect of gestational age at the time of intrauterine myelomeningocele repair on the duration of pregnancy and the gestational age at the time of delivery. This study is a retrospective chart review of the maternal and neonatal medical records of all infants undergoing intrauterine myelomeningocele repair at Vanderbilt University Medical Center. Birth weight, gestational age at the time of surgery and gestational age at the time of delivery were recorded. Infants were divided into 2 groups depending on gestational age at the time of surgery, either > or = 25 weeks' gestation (group 1) or < 25 weeks (group 2). Results were expressed as medians and interquartile ranges. Statistical analysis was done using the unpaired (2-sample) t test; p values < or = 0.05 were considered significant. Ninety-five infants were studied. Fifty-one infants were repaired after 25 weeks' gestation (group 1) at a median gestational age of 26.3 weeks (range 25.6-27.6). Their median gestational age at delivery was 34.4 weeks (range 32.6-35.3). Forty-four infants were repaired before 25 weeks' gestation (group 2). Surgery was done at a median gestational age of 23.6 weeks (range 22.4-24.5). The median gestational age at delivery was 34 weeks (range 31.6-35.3; p = 0.88). Early intrauterine myelomeningocele repair before 25 week's gestation does not decrease the gestational age at delivery when compared with repair after 25 weeks. Copyright 2002 S. Karger AG, Basel

Nitric oxide is essential in the vascular adaptation to pregnancy, as knockout mice lacking nitric oxide synthase (NOS3) have abnormal utero-placental perfusion, hypertension and growth restriction. We previously showed with ex vivo studies on transgenic animals lacking NOS3 that adverse intrauterine environment alters fetal programming of vascular reactivity in adult offspring. The current research shows that altered vascular reactivity correlates with higher blood pressure in vivo. Our data suggest that higher blood pressure depends on both genetic background (NOS3 deficiency) and uterine environment, becomes more evident with age (> 7 postnatal weeks), activity and stress, is gender specific (preponderant among males), and can be affected by the sleep-awake cycle. In utero or early postnatal life (programming is associated with abnormal blood pressure (BP) profiles in vivo. Mice lacking a functional endothelial nitric oxide synthase (KO, NOS3(-/-) ) and wild-type mice (WT, NOS3(+/+) ) were crossbred to generate homozygous NOS3(-/-) (KO), maternally derived heterozygous NOS3(+/-) (KOM: mother with adverse intrauterine environment from NOS3 deficiency), paternally derived heterozygous NOS3(+/-) (KOP: mother with normal in utero milieu) and NOS3(+/+) (WT) litters. BP was measured in vivo at 7, 14 and 21 weeks of age. After univariate analysis, multivariate population-averaged linear regression models were used to identify factors affecting BP. When compared to WT offspring, systolic (SBP), diastolic (DBP) and mean (MAP) BP progressively increased from KOP, to KOM, and peaked among KO (P 7 postnatal weeks), higher locomotor activity, daytime recordings, and recent blood pressure transducer insertion (P < 0.001). Post hoc analysis showed that KOM had higher SBP than KOP (P < 0.05). Our study indicates that adverse intrauterine environment contributes, along with multiple other factors, to account for hypertension; moreover, in utero or early postnatal life may

Full Text Available Monochorionic twin pregnancies are at increased risk of perinatal mortality and morbidity due to twin-twin transfusion syndrome (TTTS, selective intrauterine growth restriction (sIUGR, and higher incidence of congenital heart malformations. The incidence of right ventricular outflow tract obstruction (RVOTO in recipients with TTTS is known to be higher than in the general population. There is limited data on the risk of RVOTO in monochorionic twins with sIUGR. We report a case of RVOTO in the larger twin in a monochorionic twin pregnancy with sIUGR, treated successfully with balloon dilatation after birth.

We present a case of gastroschisis managed with serial amnioex-changes. Marked decreases were detected in both ferritin and bile acid levels following the procedure. The bowels were not severely affected, as expected. After delivery, single primary closure of the defect was performed. Early enteral feeding and shorter hospital stay were the main outcome measures. Intrauterine pre-treatment of gastroschisis by serial amnioexchange may provide benefits by decreasing the levels of inflammatory products in the amniotic fluid in order to lower the possible risk of bowel damage, and this may help to achieve better surgical and postnatal outcomes.

Full Text Available Placental mesenchymal dysplasia (PMD is a rare placental abnormality. We report a case of PMD associated with intrauterine growth restriction (IUGR, which was diagnosed by an ultrasound scan during the second trimester of pregnancy. A 36-year-old primiparous woman with signs of placental chorioangioma was referred to our hospital at the 23th gestational week. An ultrasonography revealed a small-for-gestational-age fetus with a large multicystic placenta. A serial Doppler sonographic assessment of umbilical and uterine artery blood flow showed a compromised fetus. A female, small-for-gestational-age baby was delivered by c-section at 28 weeks, and PMD was histopathologically confirmed.

Hospital data on 306 mother-infant pairs in Cobán, Guatemala, were studied to assess factors responsible for low infant birth weights involving the two general kinds of intrauterine growth retardation (IUGR), these being Type I (symmetric stunting) and Type II (asymmetric stunting or wasting). The results indicate that the Type I IUGR observed arose primarily from long-term poverty, malnutrition, and chronic poor living conditions, while much of the Type II IUGR seemed attributable to maternal disorders affected by short interbirth intervals.

Sixteen dairy cows with chronic puerperal endometritis between 3 and 8 weeks post partum were treated with intra-uterine applied oxytetracycline (OTC) and lugol. OTC was rapidly removed from plasma and was not detectable after 48 hours. The concentration of OTC in milk did not exceed 40 micrograms/kg, and it was still detectable in milk 34 hours after treatment. The concentration of OTC in milk was always lower than the limit of 50 micrograms/kg used by milk-testing stations and the European limit (MRL) of 100 micrograms/kg. Milk from cows treated with lugol did not cause inhibition in the plate test.

Single umbilical artery is among the most common funicular vascular anomalies. In contrast, umbilical artery stenosis is rare, and has only been reported in three-vessel cords. We describe a case of single umbilical artery stenosis in a fetus with no associated malformations. Intrauterine fetal death occurred at 28 weeks' gestation following cordocentesis and intravascular transfusion for Rhesus alloimmunization. Single umbilical artery stenosis may place the fetus at increased risk, particularly in cases requiring interventions involving cord manipulation. Copyright 2002 John Wiley & Sons, Ltd.

Cases of unexplained intrauterine fetal death (IUFD) can be reduced by full placental examination, with or without autopsy. Determination of the umbilical coiling index (UCI) is considered to be a part of full placental examination. Umbilical hypercoiling (UCI above 0.30 coils/cm) is associated with IUFD. In a large retrospective study, we found an incidence of 18% umbilical hypercoiling in IUFD. We explored the association between umbilical hypercoiling and 2nd- and 3rd-trimester IUFD in 77 cases. There was a significant negative correlation between the UCI and gestational age of IUFD (PUCI should be part of the routine placental examination of cases of IUFD.

Intrauterine insemination with cryopreserved donor semen was performed in 114 women in a total of menstrual 381 cycles during the period 1.2.1991 to 15.5.1993. Eighty-one pregnancies were recorded corresponding to a conception rate of 21% per insemination cycle. After ten cycles the probability...... of conception and expected delivery was respectively 96% and 86%. The results show that intrauterine insemination with donor semen is a good treatment for couples with male infertility. Ultrasonic measurement of the follicles and timing of hCG injection were used for optimal timing of intrauterine donor...... insemination. The quality of the semen used for insemination is important. It is recommended to inseminate with at least two million of spermatozoa where at least 20% have normal motility....
Full Text Available Magnesium deficiency in pregnancy frequently occurs because of inadequate or low intake of magnesium. Magnesium deficiency during pregnancy can induce not only maternal and fetal nutritional problems, but also consequences that might last in offspring throughout life. Many epidemiological studies have disclosed that small for gestational age (SGA is associated with an increased risk of insulin resistance in adult life. We reported that intracellular magnesium of cord blood platelets is lower in SGA groups than that in appropriate for gestational age groups, suggesting that intrauterine magnesium deficiency may result in SGA. Taken together, intrauterine magnesium deficiency in the fetus may lead to or at least program insulin resistance after birth. In this review, we propose that intrauterine magnesium deficiency may induce metabolic syndrome in later life. We discuss the potential contribution of aberrant magnesium regulation to SGA and to the pathogenesis of metabolic syndrome.

A laser device includes a virtual source configured to aim laser energy that originates from a true source. The virtual source has a vertical rotational axis during vertical motion of the virtual source and the vertical axis passes through an exit point from which the laser energy emanates independent of virtual source position. The emanating laser energy is collinear with an orientation line. The laser device includes a virtual source manipulation mechanism that positions the virtual source. The manipulation mechanism has a center of lateral pivot approximately coincident with a lateral index and a center of vertical pivot approximately coincident with a vertical index. The vertical index and lateral index intersect at an index origin. The virtual source and manipulation mechanism auto align the orientation line through the index origin during virtual source motion.
The alignment of one of the accelerator magnets being checked by the AR Division survey group. A "distinvar" device, invented by the group, using calibrated invar wires stretched between the fixed survey pillar (on the left) and a fixed point on the magnet. In two days it is thus possible to measure the alignment of the 100 magnets with an accuracy better than 1/10.

Full Text Available Objectives: There are a number of potential advantages to performing hysteroscopy in an outpatient setting. However, the ideal approach, using local uterine anesthesia or rectal non-steroidal anti-inflammatory drugs, has not been determined. Our objective was to compare the efficacy of intrauterine lidocaine instillation with rectal diclofenac for pain relief during diagnostic hysteroscopy. Methods: We conducted a double-blind randomized controlled trial on 70 nulliparous women with primary infertility undergoing diagnostic hysteroscopy. Subjects were assigned into one of two groups to receive either 100mg of rectal diclofenac or 5mL of 2% intrauterine lidocaine. The intensity of pain was measured by a numeric rating scale 0–10. Pain scoring was performed during insertion of the hysteroscope, during visualization of the intrauterine cavity, and during extrusion of the hysteroscope. Results: There were no statistically significant differences between the groups with regard to the mean pain score during intrauterine visualization (p=0.500. The mean pain score was significantly lower during insertion and extrusion of the hysteroscope in the diclofenac group (p=0.001 and p=0.030, respectively. Nine patients in the lidocaine group and five patients in diclofenac group needed supplementary intravenous propofol injection for sedation (p=0.060. Conclusions: Rectal diclofenac appears to be more effective than intrauterine lidocaine in reducing pain during insertion and extrusion of hysteroscope, but there are no significant statistical and clinical differences between the two methods with regard to the mean pain score during intrauterine inspection.
Full Text Available Heterotropic pregnancy, although a rare condition, is associated with a greater frequency in assisted reproduction. It occurs in approximately 1 in 100 pregnancies conceived by in vitro fertilization (IVF particularly when multiple embryos are transferred into the uterus. We report a case of heterotropic pregnancy following IVF with the rupture of an isthmo-cornual pregnancy at 12 weeks of gestation with uneventful progression of the intrauterine pregnancy. Laparotomy was performed for the excision of the isthmo-cornual pregnancy. The intrauterine pregnancy continued uneventfully. A female baby was delivered by elective cesarean section at 33 weeks.

Background Ulipristal (CDB-2914; UPA) is a progesterone receptor modulator with contraceptive potential. To test its effects when delivered by an intrauterine system (IUS), we prepared control and UPA-filled IUS and evaluated their effects in rhesus macaques. Study Design Short lengths of Silastic tubing either empty (n=3), or containing UPA (n=5), were inserted into the uteri of 8 ovariectomized macaques. Animals were cycled by sequential treatment with estradiol and progesterone. After 3.5 cycles, the uterus was removed. Results During treatment, animals with an empty IUS menstruated for a mean total of 11.66 ± 0.88 days while UPA-IUS treated animals bled for only 1 ± 0.45 days. Indices of endometrial proliferation were significantly reduced by UPA-IUS treatment. The UPA exposed endometria were atrophied with some glandular cysts while the blank controls displayed a proliferative morphology without cysts. Androgen receptors were more intensely stained in the glands of the UPA-IUS treated endometria than in the blank-IUS treated controls. Conclusions In rhesus macaques, a UPA-IUS induced endometrial atrophy and amenorrhea. The work provides proof of principle that an IUS can deliver effective intrauterine concentrations of Ulipristal.

The risk of type 2 diabetes is increased in children and adults who exhibited fetal growth restriction. Placental insufficiency and intrauterine growth restriction (IUGR) are common obstetrical complications associated with fetal hypoglycemia and hypoxia that reduce the β-cell mass and insulin secretion. In the present study, we have defined the underlying mechanisms of reduced growth and proliferation, impaired metabolism, and defective insulin secretion previously established as complications in islets from IUGR fetuses. In an IUGR sheep model that recapitulates human IUGR, high-throughput RNA sequencing showed the transcriptome of islets isolated from IUGR and control sheep fetuses and identified the transcripts that underlie β-cell dysfunction. Functional analysis expanded mechanisms involved in reduced proliferation and dysregulated metabolism that include specific cell cycle regulators and growth factors and mitochondrial, antioxidant, and exocytotic genes. These data also identified immune responses, wnt signaling, adaptive stress responses, and the proteasome as mechanisms of β-cell dysfunction. The reduction of immune-related gene expression did not reflect a change in macrophage density within IUGR islets. The present study reports the islet transcriptome in fetal sheep and established processes that limit insulin secretion and β-cell growth in fetuses with IUGR, which could explain the susceptibility to premature islet failure in adulthood. Islet dysfunction formed by intrauterine growth restriction increases the risk for diabetes. Copyright © 2017 Endocrine Society.

During the cocaine epidemic of the 1980s and early 1990s, many expressed fears that children with intrauterine cocaine exposure (IUCE) would grow up to be unusually violent. The present study examines the relationship of caregiver reports of school-age children's aggressive behavior with IUCE and postnatal exposure to violence. Respondents were 140 low-income, primarily African American children, ages 8-11, and each child's current primary caregiver from a longitudinal study evaluating potential long term sequelae of IUCE. Multiple regression analyses were used to investigate the independent and interactive effects of level of IUCE (None (n = 69), Lighter (n = 47), Heavier (n = 24)) and exposure to violence (Violence Exposure Scale for Children-Revised) on aggressive behavior (Child Behavior Checklist), while also controlling for other intrauterine substance exposures and additional contextual factors. Children's self-reported exposure to violence was significantly positively associated with caregivers' reports of aggressive behavior (β = 2.17, P = .05), as was concurrent caregiver's psychiatric distress (β = .15, P = .003). However, neither IUCE nor its interaction with exposure to violence showed a significant association with aggressive behavior. Findings suggest the importance of postnatal social environment rather than IUCE in predicting aggressive behavior in childhood. © 2015 Wiley Periodicals, Inc.

Data on the effect of maternal malnutrition and/or anemia on thyroid hormone regulation in human fetuses are scarce, and would be of great importance in examining the relevance of Barker's hypothesis, which proposes adaptation of fetuses to undernutrition leading to permanent metabolic and endocrine changes that form the basis of adult diseases. To examine the quantitative variations in thyroid hormone profile of neonates born to malnourished and/or anemic mothers, we quantitated the T3, T4, rT3 and TSH levels in cord blood of neonates and maternal blood of their corresponding mothers that are malnourished and/or anemic. Further, we classified neonates born to each of these groups of mothers into Small for Gestational Age (SGA) or Appropriate for Gestational Age (AGA) based on the intrauterine growth curve for our population, and examined the thyroid hormone profile in these neonates. Our results show that firstly, the effects of malnutrition or anemia on thyroid hormone profile are distinct, secondly, significantly higher levels of cord blood T4 and correspondingly lower levels of T3 and rT3 are observed in the neonates born to anemic and malnourished mothers and thirdly, decreases in cord blood T3 levels were observed in Small for Gestational Age neonates born to anemic mothers. These observations lead us to speculate that alterations in the pituitary-thyroid function result in beneficial adaptations to the hostile intrauterine environment in malnutrition related growth retardation and anemia.

Both bone mass by densitometry and speed of sound (SOS) from quantitative ultrasound of the bone (QUS) are directly related to bone strength. However, reports of lower bone mass but higher SOS in neonates with intrauterine growth deficit lead to apparent contradictory conclusions on bone strength. Three groups of infants were studied: small for gestation (SGA) with birth weights ≤10th percentile for gestation and 2 control groups with appropriate birth weights (11th to 90th percentile) for gestation (AGA): matched to SGA group for gestation and birth weight, respectively. SOS was measured with a commercial QUS instrument (Sunlight Omnisense 7000, Sunlight Medical Ltd, Tel Aviv, Israel) and 2 manufacturer supplied ultrasound probes (CS and CR) for small bones. The SGA group had significantly (p<0.01) higher SOS compared with weight matched but gestational less matured control group by an average of 54m/s with the CS probe and 80m/s with the CR probe but not significantly different from gestation-matched AGA group. SOS values from both probes were significantly correlated (r=0.71-0.91) but were significantly different between probes. Probe failure occurred with both probes. We conclude that QUS SOS values in SGA neonates are a reflection of a continuum of intrauterine maturation of the skeleton. Copyright © 2011 The International Society for Clinical Densitometry.

In computer science in general and in particular the field of high performance computing and supercomputing the term scalable plays an important role. It indicates that a piece of hardware, a concept, an algorithm, or an entire system scales with the size of the problem, i.e., it can not only be used in a very specific setting but it\\'s applicable for a wide range of problems. From small scenarios to possibly very large settings. In this spirit, there exist a number of fixed areas of research on scalability. There are works on scalable algorithms, scalable architectures but what are scalable devices? In the context of this chapter, we are interested in a whole range of display devices, ranging from small scale hardware such as tablet computers, pads, smart-phones etc. up to large tiled display walls. What interests us mostly is not so much the hardware setup but mostly the visualization algorithms behind these display systems that scale from your average smart phone up to the largest gigapixel display walls.

Full Text Available Abstract Background Intrauterine growth restriction (IUGR is associated with several medical complications before and after delivery. The aim of this study was to evaluate the concordance between the fetal ultrasonographic measurement of subcutaneous tissue thicknesses and the skinfold thicknesses assessment in intrauterine growth restricted newborns. Methods We designed an exploratory study. Fetal ultrasonographic measurement of subcutaneous tissue thicknesses, according to Bernstein's and Galan's method, and neonatal skinfold thicknesses were evaluated in 13 intrauterine growth restricted newborns within 4 hours before delivery and on the first day of life, respectively. Concordance between fetal and neonatal measurements was assessed using the Lin's correlation coefficient and the Bland-Altman method. Results The data obtained by the measurements of neonatal skinfold thicknesses was significantly correlated with the prenatal measurements (Lin's coefficients, arm: 0.60; subscapular: 0.72; abdomen: 0.51. Bland-Altman analysis showed moderate agreement between the fetal ultrasonographic measurement of subcutaneous tissue thicknesses and the neonatal skinfold thicknesses assessment. Conclusions The present study provides preliminary evidence that fetal sonographic measurements may represent additional indices of intrauterine growth restriction.

Endometrial trauma caused by surgery or infection can result in the development of intrauterine adhesions. In standard clinical practice there are several methods which can be used to diagnose adhesions in symptomatic women, but there are no descriptions of morphological features which precede their formation. As a result, there is currently no effective treatment which could be used to prevent development of intrauterine adhesions in high-risk women. This case series describes distinctive appearances of the uterine cavity which were observed on transvaginal ultrasound scans in a group of symptomatic women prior to the development of intrauterine adhesions. All women had undergone surgical evacuation of retained placenta or products of conception prior to the examination and they all developed similar changes within the endometrial cavity before intrauterine adhesions were detected on follow up examinations. These findings indicate that in some women there is a time delay between endometrial trauma and development of adhesions which could facilitate development of strategies for their secondary prevention in the future.

A quick opening type of stuffing box employing two banks of rotatable shoes, each of which has a caraming action that forces a neoprene sealing surface against a pipe or rod where it passes through a wall is presented. A ring having a handle or wrench attached is placed eccentric to and between the two banks of shoes. Head bolts from the shoes fit into slots in this ring, which are so arranged that when the ring is rotated a quarter turn in one direction the shoes are thrust inwardly to cramp the neopnrene about the pipe, malting a tight seal. Moving the ring in the reverse direction moves the shoes outwardly and frees the pipe which then may be readily removed from the stuffing box. This device has particular application as a closure for the end of a coolant tube of a neutronic reactor.

Maternal infection is a risk factor for periventricular leukomalacia and cerebral palsy (CP) in neonates. We have previously demonstrated hypomyelination and motor deficits in newborn rabbits, as seen in patients with cerebral palsy, following maternal intrauterine endotoxin administration. This was associated with increased microglial activation, primarily involving the periventricular region (PVR). In this study we hypothesized that maternal intrauterine inflammation leads to a pro-inflammatory environment in the PVR that is associated with microglial activation in the first 2 postnatal weeks. Timed pregnant New Zealand white rabbits underwent laparotomy on gestational day 28 (G28). They were randomly divided to receive lipopolysaccharide (LPS; 20μg/kg in 1mL saline) (Endotoxin group) or saline (1mL) (control saline, CS group), administrated along the wall of the uterus. The PVR from the CS and Endotoxin kits were harvested at G29 (1day post-injury), postnatal day1 (PND1, 3day post-injury) and PND5 (7days post-injury) for real-time PCR, ELISA and immunohistochemistry. Kits from CS and Endotoxin groups underwent longitudinal MicroPET imaging, with [ 11 C]PK11195, a tracer for microglial activation. We found that intrauterine endotoxin exposure resulted in pro-inflammatory microglial activation in the PVR of rabbits in the first postnatal week. This was evidenced by increased TSPO (translocator protein) expression co-localized with microglia/macrophages in the PVR, and changes in the microglial morphology (ameboid soma and retracted processes). In addition, CD11b level significantly increased with a concomitant decline in the CD45 level in the PVR at G29 and PND1. There was a significant elevation of pro-inflammatory cytokines and iNOS, and decreased anti-inflammatory markers in the Endotoxin kits at G29, PND1 and PND5. Increased [ 11 C]PK11195 binding to the TSPO measured in vivo by PET imaging in the brain of Endotoxin kits was present up to PND14-17. Our

Impaired trophoblast invasion into spiral arteries is associated with early-onset intrauterine growth restriction and preeclampsia. We compared trophoblast invasion into spiral arteries in pregnancies with maternal anemia or early-onset preeclampsia/intrauterine growth restriction and related these findings to trophoblast apoptosis. Full-thickness uterine wall samples were obtained from women with early-onset preeclampsia/intrauterine growth restriction (n = 6), normal pregnancies (n = 5), and chronic anemia (n = 8). Trophoblast invasion into the walls of spiral arteries was quantified by morphometric analysis of paraffin sections stained with anticytokeratin 18, antiactin, and anticytokeratin 18 neoepitope (M30) antibodies. Trophoblast invasion into spiral arteries was increased in anemic pregnancies (mean [SD]: 206  cell profiles/mm2) and severely impaired in preeclamptic/intrauterine growth restriction pregnancies (17 ), compared with normal subjects (149 ). Spiral artery lumen area was increased in anemia (0.07 [0.03] mm2) versus normal pregnancies (0.09 [0.04] mm2) and reduced in preeclampsia/intrauterine growth restriction (0.04 [0.02] mm2). Trophoblast apoptosis was similar in anemic (4.2% [3.4%]) and normal (5.0% [1.9%]) pregnancies but increased in preeclampsia/intrauterine growth restriction (12% [5.6%]). Trophoblast invasion into the placental bed in early-onset preeclampsia/intrauterine growth restriction is limited by increased apoptosis, resulting in narrower spiral arteries, which is in contrast to findings in anemia.
Full Text Available Objective: to identify risk factors that adversely affect the development of fetus and child small for gestational age; to assess the incidence of the intrauterine development of fetus and newborn; to analyze the health indicators of these children. Material and Methods. Cases of 226 children (6.6% with diagnosed intrauterine growth restriction of the fetus were examined, including 134 of prematurity (59%. Results. The most common risk factors for the intrauterine development of the fetus were: violation of the utero-placental circulation — 196 cases, the uterine scar — 78 women, urinary tract infection — 94. Extragenital pathology was found in all women, the threat of termination of pregnancy in 109 cases, medical history of abortions in 106 women and 83 anaemia in women. Birth asphyxia was observed in 102 children (45%, prematurity in 71 cases (31.4%. Asphyxia of severe degree accounted 1 (0.5% premature and 1 (0.45% full-term baby. Asphyxia of moderate severity (4-6 points accounted 70 (30.9% preterm and 31 (13.7% full-term infants. The most common form of the intrauterine development of the fetus asymmetrical revealed 178 cases (79.1%. Conclusion: Perinatal factors such as medical abortion, urinary tract infection, extragenital pathology are preventable. The predominant form of the intrauterine development of the fetus is asymmetric form, symmetric and dysplastic revealed to a greater degree in premature infants. Children with low weight for gestational age should be adequately provided with the necessary nutrients, fortifiers, vitamins and in the process of rehabilitation — cerebropro-tective therapy.

The levonorgestrel intrauterine system (LNG IUS) is one of the most effective forms of contraception and offers important non-contraceptive health benefits. However, it is not widely available in developing countries, largely due to the high price of existing products. Medicines360 plans to introduce its new, more affordable LNG IUS in Kenya. The public-sector transfer price will vary by volume between US$12 to US$16 per unit; for an order of 100,000 units, the public-sector transfer price will be approximately US$15 per unit. We calculated the direct service delivery cost per couple-years of protection (CYP) of various family planning methods. The model includes the costs of contraceptive commodities, consumable supplies, instruments per client visit, and direct labor for counseling, insertion, removal, and resupply, if required. The model does not include costs of demand creation or training. We conducted interviews with key opinion leaders in Kenya to identify considerations for scale-up of a new LNG IUS, including strategies to overcome barriers that have contributed to low uptake of the copper intrauterine device. The direct service delivery cost of Medicines360's LNG IUS per CYP compares favorably with other contraceptive methods commonly procured for public-sector distribution in Kenya. The cost is slightly lower than that of the 3-month contraceptive injectable, which is currently the most popular method in Kenya. Almost all key opinion leaders agreed that introducing a more affordable LNG IUS could increase demand and uptake of the method. They thought that women seeking the product's non-contraceptive health benefits would be a key market segment, and most agreed that the reduced menstrual bleeding associated with the method would likely be viewed as an advantage. The key opinion leaders indicated that myths and misconceptions among providers and clients about IUDs must be addressed, and that demand creation and provider training should be prioritized
Full Text Available Aim: Intrauterine insemination is a widely used technique with advantages of being a simple and less invasive method with a lower cost when compared to other assisted reproductive techniques. In the present prospective randomized controlled study we aim to prove that progesterone supplementation is a beneficial factor in pregnancies achieved with intra uterine insemination and also we want to emphasise that luteal phase deficiency does not always occur in multifollicular cycles but can be seen in unifollicular cycles as well. Material and Method: Patients diagnosed with unexplained infertility between December 2011 and December 2012 were admitted to the study group. 278 IUI cycles with COH using recombinant FSH induction were recorded. Results: The effect of progesterone supplement on achieving pregnancy was statistically significant (p

Uterine arteriovenous malformation (AVM) is a rare entity in gynecology with fewer than 100 cases reported in the literature. Due to abnormal connection between arteries and veins without an intervening capillary system, recurrent and profuse vaginal bleeding is the most common symptom which can be potentially life-threatening. Uterine AVM can be either congenital or acquired. Acquired AVM is reported as a consequence of previous uterine trauma such as curettage procedures, caesarean section or pelvic surgery. It is also associated with infection, retained product of conception, gestational trophoblastic disease, malignancy and exposure to diethlystilboestrol. We herein report a case of acquired uterine AVM located on the right lateral wall after intrauterine instrumentation for laparoscopic left salpingectomy due to left tubal pregnancy. The patient was successfully treated with embolization.
Full Text Available Intrauterine growth restriction (IUGR implies fetal hypoxia, resulting in blood flow redistribution and sparing of vital organs (brain, heart. Serum cardiac Troponin-I (cTnI, a well-established marker of myocardial ischaemia, was measured in 40 mothers prior to delivery, the doubly clamped umbilical cords (representing fetal state, and their 20 IUGR and 20 appropriate-for-gestational-age (AGA neonates on day 1 and 4 postpartum. At all time points, no differences in cTnI levels were observed between the AGA and IUGR groups. Strong positive correlations were documented between maternal and fetal/neonatal values (r≥.498, P≤.025 in all cases in the AGA and r≥.615, P≤.009 in all cases in the IUGR group. These results may indicate (a normal heart function, due to heart sparing, in the IUGR group (b potential crossing of the placental barrier by cTnI in both groups

Intrauterine growth restriction (IUGR) is a fetal complication of pregnancy epidemiologically linked to cardiovascular disease in the newborn later in life. However, the mechanism is poorly understood with very little research on the vascular structure and function during development in healthy and IUGR neonates. Previously, we found vascular remodeling and increased stiffness in the carotid and umbilical arteries, but here we examine the remodeling and biomechanics in the larger vessels more proximal to the heart. To study this question, thoracic and abdominal aortas were collected from a sheep model of placental insufficiency IUGR (PI-IUGR) due to exposure to elevated ambient temperatures. Aortas from control (n = 12) and PI-IUGR fetuses (n = 10) were analyzed for functional biomechanics and structural remodeling. PI-IUGR aortas had a significant increase in stiffness (P IUGR may set the stage for possible altered growth and development and help to explain the pathophysiology of adult cardiovascular disease in previously IUGR individuals.

Background We hypothesized intrauterine growth restricted offspring (IUGR) demonstrate higher rates of aggression and higher dominance ranks than control (CTR) offspring with normal weight at term; if aggressive behavior is advantageous during resource scarcity, developmental programming may lead to an association between aggression and IUGR. Methods We studied 22 group-housed baboons (ages 3-5 years). CTR (male n=8, female n=5) mothers ate ad libitum. IUGR (male n=4, female n=5) mothers were fed 70% feed eaten by CTR mothers during pregnancy and lactation. Results IUGR showed higher rates of aggressive displays (pIUGR aggressive display might reflect developmental programming of behavioral phenotypes enhancing fitness. Friendly displays may reflect reconciliation. Potential mechanisms include neurodevelopment and learning. Exploration of IUGR as a risk factor for behavioral patterns is important for developing diagnostic and therapeutic strategies. PMID:25891005

Uteroplacental tissue plays a key role in substance exchanges between maternal and fetal circulation, and, therefore, in the growth and development of fetuses. In this study, proteomics and western blotting were applied to investigate the changes of proteome in the placenta and endometrium of normal and intrauterine growth restriction (IUGR) porcine fetuses during mid to late pregnancy (D60, 90, and 110 of gestation). Our results showed that proteins participating in cell structure, energy metabolism, stress response, cell turnover, as well as transport and metabolism of nutrients were differentially expressed in placenta and endometrium between normal and IUGR fetuses. Analysis of functions of these proteins suggests reductions in ATP production and nutrients transport, increases in oxidative stress and apoptosis, and impairment of cell metabolism in IUGR fetuses. Collectively, our findings aid in understanding of the mechanisms responsible for uteroplacental dysfunction in IUGR fetus, and are expected to provide new strategies to reduce fetal growth restriction in pigs and other mammals.

Heterotopic pregnancies are rare and are usually diagnosed by transvaginal ultrasound. Despite the routine use of sonography in early pregnancy, artifact created by mirror imaging can drastically and erroneously alter medical decision making by interfering with image interpretation. A heterotopic pregnancy with a single intrauterine gestation and twin left adnexal ectopic gestational sacs was observed on ultrasound in a woman presenting with abdominal pain. During laparoscopy, an ectopic pregnancy was not identified, and subsequent intraoperative ultrasound reproduced the heterotopic pregnancy through manipulation of bowel, confirming mirror image artifact. This phenomenon is rarely seen in obstetric imaging; therefore, lack of awareness can lead to false diagnosis of heterotopic pregnancy. Techniques to verify correct diagnosis should be used to resolve potential mirror artifact before proceeding with surgical management.

Intrauterine growth restriction (IUGR) confers heritable alterations in DNA methylation, rendering risk of adult metabolic syndrome (MetS). Because CpG methylation is coupled to intake of essential nutrients along the one-carbon pathway, we reasoned that essential nutrient supplementation (ENS) may abrogate IUGR-conferred multigenerational MetS. Pregnant Sprague-Dawley rats underwent bilateral uterine artery ligation causing IUGR in F1. Among the F2 generation, IUGR lineage rats were underweight at birth (6.7 vs. 8.0 g, P adulthood (p160: 613 vs. 510 g; P 30% elevated, P 5-fold less central fat mass, normal hepatic glucose efflux, and >70% reduced circulating triglycerides and very-LDLs compared with IUGR control-fed F2 offspring (P supplementation along the one-carbon pathway abrogates adult morbidity and associated epigenomic modifications of IGF-1 in a rodent model of multigenerational MetS. © FASEB.
Full Text Available Rhabdomyoma, a benign hamartomatous tumor of the cardiac embryonic myocyte, is the most common intrauterine cardiac tumor and accounts for 0.12% of prenatal fetal studies. Fetal cardiac rhabdomyomas increase in size during second and early third trimester and spontaneously regress postnatally. The clinical presentation is usually benign, however, compromise of the ventricular outflow tract leading to decreased cardiac output and fetal death have been reported. We present a case of large cardiac rhabdomyoma in a fetus that might have caused complete left ventricular outflow tract obstruction and development of hypoplastic left heart syndrome (HLHS necessitating postnatal single ventricle palliation therapy. The clinical course and outcomes of prenatally diagnosed cardiac rhabdomyoma are reviewed and theories of the development of hypoplastic left heart syndrome are explored.

An epidemic of Ross River virus (RRV) infection occurred in the Cook Islands in early 1980, and infected about 70% of the adult population of Rarotonga, the most populous island of the group. In July 1981, 80 mothers were identified as having been in the first trimester of pregnancy during the outbreak. Fifty-two of the at-risk mothers along with 63 of the offspring were ultimately examined. Of these 52 mothers, 39 (75%) were found to have serological evidence of RRV infection. Of the 63 infants located, 52 were examined serologically. None of the infants examined had serological evidence of RRV infection. There was no difference in age, size, or malformation rate in the offspring of the serologically positive or serologically negative mothers. These studies do not support an earlier report that RRV causes intrauterine infection.

Pubertal growth contributes to 15-18% of adult height. A blunted pubertal peak could contribute to short adult height in short children born with intrauterine growth retardation (IUGR). Pubertal growth, from onset of puberty to final height, was investigated in 75 short IUGR children: 47 were treated with recombinant human growth hormone (GH) (tx) before pubertal onset (mean dose: 0.4 IU/kg/week); 28 were not treated (no-tx). They were compared with 98 normal children. Puberty occurred later in IUGR children than in controls (boys 14.2 +/- 1 years vs. 12.1 +/- 0.8 years; girls 12 +/- 1 years vs. 11.2 +/- 0.8 years; p pubertal spurt, a finding that should be further evaluated in clinical trials.

Zika virus (ZIKV) crosses the placenta and causes congenital disease. Here we develop an animal model utilizing direct ZIKV inoculation into the uterine wall of pregnant, immunocompetent mice to evaluate transplacental transmission. Intrauterine inoculation at embryonic day (E) 10, but not E14, with African, Asian or American strains of ZIKV reduces fetal viability and increases infection of placental and fetal tissues. ZIKV inoculation at E10 causes placental inflammation, placental dysfunction and reduces neonatal brain cortical thickness, which is associated with increased activation of microglia. Viral antigen localizes in trophoblast and endothelial cells in the placenta, and endothelial, microglial and neural progenitor cells in the fetal brain. ZIKV infection of the placenta increases production of IFNβ and expression of IFN-stimulated genes 48 h after infection. This mouse model provides a platform for identifying factors at the maternal–fetal interface that contribute to adverse perinatal outcomes in a host with an intact immune system. PMID:28220786

Fetal and neonatal haemolytic diseases result from maternal allo-immunisation to fetal antigens. Maternal antibodies cross the placenta causing red cell haemolysis, resulting in fetal anaemia and, in severe cases, hydrops and perinatal death. Intravascular intrauterine blood transfusion (IUT) has markedly reduced perinatal mortality and is now a standard procedure. IUT is considered to be a safe procedure with fetal loss rate reported to be less than 5% and no reported increase in the rate of neurodevelopment impairment. In this report, we are presenting a case of bilateral cystic encephalomalacia following fetal anaemia secondary to anti-Kell iso-immunisation treated with multiple IUTs. Such a significant adverse outcome following IUT for anti-Kell iso-immunisation has not been reported in the literature. This case highlights the need for appropriate parental counselling and routine postnatal head ultrasound in all babies delivered following multiple IUTs. 2015 BMJ Publishing Group Ltd.
Full Text Available Intrauterine extremity gangrene in combination with cerebral infarction is a serious and rare event. We present a case with a healthy mother who gave birth to a child with this condition. At term, the mother presented at the antenatal clinic with decreased fetal movements. Cardiotocography (CTG showed signs of fetal distress and a caesarean section was performed. The left arm of the newborn was found gangrenous. Amputation of the arm was necessary and the child was subsequently treated with anticoagulant therapy due to thrombosis and cerebral infarction in the left hemisphere found by magnetic resonance imaging (MRI. At one year of age the boy was doing well and had prosthesis as a left arm. He had no signs of further complications. Despite thorough examination of the parents and the child, the reason for the thrombosis is still unknown.

Intrauterine myelomeningocele repair (IUMR) was first successfully performed in 1997. Preliminary reports suggest that this procedure reduces the incidence of shunt-dependent hydrocephalus when compared to conventional postnatal therapy. However, the existing cohort of IUMR patients has not yet been systematically compared to a comparable group of conventionally treated controls. Patients 1 year old or greater who had undergone IUMR at either Vanderbilt University or the Children's Hospital of Philadelphia (CHOP) were compared to a group of conventionally treated historical controls treated and followed at CHOP. In order to measure any differences between the groups, patients were stratified according to the level of the myelomeningocele lesion and the gestational age at the time of IUMR. One hundred and four IUMR patients were compared to 189 conventionally treated controls. IUMR resulted in statistically significant reductions in the incidence of shunt-dependent hydrocephalus at both lumbar and sacral lesion levels. When lumbar lesion levels were further stratified, from L1 to L5, it appeared that the benefit of IUMR was statistically significant only at levels below L2. Other factors with a significant impact on hydrocephalus were estimated gestational age and ventricular size at the time of surgery. In particular, statistically significant differences compared to controls were seen in the younger (25 weeks) group. IUMR appears to substantially reduce the incidence of shunt-dependent hydrocephalus when compared to conventional treatment even when lesion level is taken into account. Patients with lesions above L3 may not share in this benefit. IUMR cannot be justified in fetuses older than 25 weeks of gestation. Additional improvements might be obtained by further reducing the average age at which fetuses are operated upon. It remains to be determined whether this benefit outweighs the potential risks of intrauterine surgery. Copyright 2003 S. Karger AG, Basel

To determine whether short-term complications of prematurity are affected by intrauterine myelomeningocele repair. Medical records of the first 100 infants undergoing intrauterine myelomeningocele repair (IUMR) at the Vanderbilt University Medical Center were reviewed. Infants born at <34 weeks' gestation were identified. Two controls were identified for each IUMR infant. Controls were matched for gestational age, sex, birth weight, antenatal steroids, and mode and month of delivery. Development of respiratory distress syndrome, intraventricular hemorrhage, and chronic lung disease and days on ventilator and length of hospital stay were recorded. The results are expressed as mean values and ranges. Comparison of data between groups was performed using the Mann-Whitney U test. Categorical data were compared using the chi-square test and Fisher's exact test. p = 0.05 was considered statistically significant. One hundred infants underwent IUMR. Forty-four infants were born at <34 weeks of gestation. Complete data were available on 37 infants. Seventy-four matched controls were studied. Eleven infants from the IUMR group and 23 infants from the control group developed respiratory distress syndrome (29.7 vs. 31.1%; p = 0.8). Six infants from the IUMR group and 13 infants from the control group developed chronic lung disease (16.2 vs. 17.5%; p = 0.9). The length of stay was 28 (range 2-82) days for the IUMR group and 24 (range 1-99) days (p = 0.09) for the control group. There was also no significant difference between groups with regard to intraventricular hemorrhage and days on ventilators. There is no difference between short-term complications of prematurity following IUMR and those associated with prematurity resulting from other causes. Copyright 2004 S. Karger AG, Basel

Placental insufficiency alters the intrauterine environment leading to increased risk for chronic disease including impaired glucose metabolism in low birth weight infants. Using a rat model of low birth weight, we previously reported that placental insufficiency induces a significant increase in circulating testosterone in male intrauterine growth-restricted offspring (mIUGR) in early adulthood that is lost by 12 months of age. Numerous studies indicate testosterone has a positive effect on glucose metabolism in men. Female growth-restricted littermates exhibit glucose intolerance at 6 months of age. Thus, the aim of this paper was to determine whether mIUGR develop impaired glucose metabolism, and whether a decrease in elevated testosterone levels plays a role in its onset. Male growth-restricted offspring were studied at 6 and 12 months of age. No impairment in glucose tolerance was observed at 6 months of age when mIUGR exhibited a 2-fold higher testosterone level compared to age-matched control. Fasting blood glucose was significantly higher and glucose tolerance was impaired with a significant decrease in circulating testosterone in mIUGR at 12 compared with 6 months of age. Castration did not additionally impair fasting blood glucose or glucose tolerance in mIUGR at 12 months of age, but fasting blood glucose was significantly elevated in castrated controls. Restoration of elevated testosterone levels significantly reduced fasting blood glucose and improved glucose tolerance in mIUGR. Thus, our findings suggest that the endogenous increase in circulating testosterone in mIUGR is protective against impaired glucose homeostasis.

To investigate the association of non-cavity-distorting uterine fibroids and pregnancy outcomes after ovarian stimulation-intrauterine insemination (OS-IUI) in couples with unexplained infertility. Secondary analysis from a prospective, randomized, multicenter clinical trial investigating fertility outcomes after OS-IUI. Reproductive Medicine Network clinical sites. Nine hundred couples with unexplained infertility who participated in the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) clinical trial. Participants were randomized to one of three arms (clomiphene citrate, letrozole, or gonadotropins), and treatment was continued for up to four cycles or until pregnancy was achieved. Conception (serum hCG increase), clinical pregnancy (fetal cardiac activity), and live birth rates. A total of 102/900 participants (11.3%) had at least one documented fibroid and a normal uterine cavity. Women with fibroids were older, more likely to be African American, had a greater uterine volume, lower serum antimüllerian hormone levels, and fewer antral follicles than women without fibroids. In conception cycles, clinical pregnancy rates were significantly lower in participants with fibroids than in those without uterine fibroids. Pregnancy loss before 12 weeks was more likely in African American women with fibroids compared with non-African American women with fibroids. There was no difference in conception and live birth rates in subjects with and without fibroids. No differences were observed in conception and live birth rates in women with non-cavity-distorting fibroids and those without fibroids. These findings provide reassurance that pregnancy success is not impacted in couples with non-cavity-distorting fibroids undergoing OS-IUI for unexplained infertility. NCT01044862.

Intrauterine plant oil infusion, including fractionated coconut oil, has been previously found to be a safe, inexpensive, and reversible method of prolonging the luteal phase in mares when administered on Day 10 of the estrous cycle. Our objective was to understand the uteroovarian response to the administration of fractionated coconut oil infusion in the uterus of diestrous mares. We hypothesized that intrauterine coconut oil administration on Day 10 would prolong luteal life span in a dose-dependent fashion and would result in higher serum progesterone levels than untreated mares at the expected time of luteolysis. Light-horse mares (n = 18) were examined using transrectal palpation and ultrasonography to determine if they had a normal interovulatory interval and were then examined daily in estrus until the day of ovulation (Day 0) and then every other day during an estrous cycle. Jugular blood was drawn on Day 11, Day 13, Day 15, and Day 17, centrifuged, and serum stored until assayed for progesterone (P4; Siemens Coat-a-Count Progesterone RIA, Los Angeles, CA, USA). Mares were randomly assigned to treatment and studied over one to two estrous cycles with a rest cycle after each treatment cycle. Groups were: control (n = 5), fractionated coconut oil 1.0 mL (Miglyol 810; Sasol Oil, Witten, Germany) infused in the uterus with an artificial insemination pipette on Day 10 (Group 1; n = 5) and fractionated coconut oil 0.5 mL infused in the uterus with an embryo transfer gun, on Day 10 (Group 2; n = 5). All statistical analyses were performed using analytical software (Stata SE, version 13.1, College Station, TX, USA) at P coconut oil lowered P4 levels in diestrus in a dose-dependent fashion and did not prolonged the luteal phase of the mares.

To determine labour management procedures associated with an increased risk of fetal heart rate anomalies and to assess the effectiveness of various intrauterine resuscitation techniques for fetal distress. The literature search was carried out systematically on Medline and Cochrane database between 1980 and June 2007 was performed. Early amniotomy and/or active management of labour reduce the duration of the first stage of labour without affecting the rate of caesarean section (level of evidence 1). Early amniotomy increases the frequency of severe variable fetal heart rate decelerations (level of evidence 1). High doses of oxytocin and decrease in the oxytocin-dosing interval for augmentation of labour both induce uterine hyperstimulation (level of evidence 1). Increased uterine activity is associated with a higher incidence of fetal heart rate abnormalities and neonatal acidosis (level of evidence 3). Fetal heart rate decelerations in supine position may disappear in the lateral position (level of evidence 3). In prophylactic maternal oxygenation administration abnormal cord blood pH values (less than 7.2) are more frequent in the oxygenation group than in the control group (level of evidence 2) and its efficacy in fetal distress is not evaluated until now. Amnioinfusion in the presence of thick meconium staining does not reduce the risk of perinatal death or meconium aspiration syndrome (level of evidence 1). Transcervical saline amnioinfusion might relieve variable decelerations during labour (level of evidence 3). Prophylactic amnioinfusion for intrapartum oligohydramnios reduces fetal heart rate abnormalities and overall rates of caesarean deliveries (level of evidence 2). Acute tocolysis may be helpful in cases of intrapartum fetal distress related to uterine hyperactivity (level of evidence 2). Early amniotomy and high doses of oxytocin may both increase the risk of fetal heart rate anomalies, but are both useful for avoiding prolonged labour. More

Studies report that fetal exposure to paracetamol/acetaminophen by maternal consumption can interfere with male reproductive development. Moreover, recent biomonitoring data report widespread presence of paracetamol in German and Danish populations, suggesting exposure via secondary (nonpharmaceutical) sources, such as metabolic conversion from the ubiquitous industrial compound aniline. In this study, we investigated the extent to which paracetamol and aniline can interfere with female reproductive development. Intrauterine exposure to paracetamol by gavage of pregnant dams resulted in shortening of the anogenital distance in adult offspring, suggesting that fetal hormone signaling had been disturbed. Female offspring of paracetamol-exposed mothers had ovaries with diminished follicle reserve and reduced fertility. Fetal gonads of exposed animals had also reduced gonocyte numbers, suggesting that the reduced follicle count in adults could be due to early disruption of germ cell development. However, ex vivo cultures of ovaries from 12.5 days post coitum fetuses showed no decrease in proliferation or expression following exposure to paracetamol. This suggests that the effect of paracetamol occurs prior to this developmental stage. Accordingly, using embryonic stem cells as a proxy for primordial germ cells we show that paracetamol is an inhibitor of cellular proliferation, but without cytotoxic effects. Collectively, our data show that intrauterine exposure to paracetamol at levels commonly observed in pregnant women, as well as its precursor aniline, may block primordial germ cell proliferation, ultimately leading to reduced follicle reserves and compromised reproductive capacity later in life. © The Author 2016.

Full Text Available The aims of this study were to analyze the predictive factors for the use of intrauterine balloon insertion and to evaluate the efficacy and factors affecting failure of uterine tamponade with a Bakri balloon during cesarean section for abnormal placentation.We reviewed the medical records of 137 patients who underwent elective cesarean section for placenta previa between July 2009 and March 2014. Cesarean section and Bakri balloon insertion were performed by a single qualified surgeon. The Bakri balloon was applied when blood loss during cesarean delivery exceeded 1,000 mL.Sixty-four patients (46.7% required uterine balloon tamponade during cesarean section due to postpartum bleeding from the lower uterine segment, of whom 50 (78.1% had placenta previa totalis. The overall success rate was 75% (48/64 for placenta previa patients. Previous cesarean section history, anterior placenta, peripartum platelet count, and disseminated intravascular coagulopathy all significantly differed according to balloon success or failure (all p<0.05. The drainage amount over 1 hour was 500 mL (20-1200 mL in the balloon failure group and 60 mL (5-500 mL in the balloon success group (p<0.01.Intrauterine tamponade with a Bakri balloon is an adequate adjunct management for postpartum hemorrhage following cesarean section for placenta previa to preserve the uterus. This method is simple to apply, non-invasive, and inexpensive. However, possible factors related to failure of Bakri balloon tamponade for placenta previa patients such as prior cesarean section history, anterior placentation, thrombocytopenia, presence of DIC at the time of catheter insertion, and catheter drainage volume more than 500 mL within 1 hour of catheter placement should be recognized, and the next-line management should be prepared in advance.

Full Text Available The mechanisms used to coordinate uterine contractions are not known. We develop a new model based on the proposal that there is a maximum distance to which action potentials can propagate in the uterine wall. This establishes "regions", where one action potential burst can rapidly recruit all the tissue. Regions are recruited into an organ-level contraction via a stretch-initiated contraction mechanism (myometrial myogenic response. Each uterine contraction begins with a regional contraction, which slightly increases intrauterine pressure. Higher pressure raises tension throughout the uterine wall, which initiates contractions of more regions and further increases pressure. The positive feedback synchronizes regional contractions into an organ-level contraction. Cellular automaton (CA simulations are performed with Mathematica. Each "cell" is a region that is assigned an action potential threshold. An anatomy sensitivity factor converts intrauterine pressure to regional tension through the Law of Laplace. A regional contraction occurs when regional tension exceeds regional threshold. Other input variables are: starting and minimum pressure, burst and refractory period durations, enhanced contractile activity during an electrical burst, and reduced activity during the refractory period. Complex patterns of pressure development are seen that mimic the contraction patterns observed in laboring women. Emergent behavior is observed, including global synchronization, multiple pace making regions, and system memory of prior conditions. The complex effects of nifedipine and oxytocin exposure are simulated. The force produced can vary as a nonlinear function of the number of regions. The simulation directly links tissue-level physiology to human labor. The concept of a uterine pacemaker is re-evaluated because pace making activity may occur well before expression of a contraction. We propose a new classification system for biological CAs that parallels

The objective was to assess risk of pelvic inflammatory disease (PID) among women with current asymptomatic undiagnosed cervical infection or who are at high risk of sexually transmitted infections (STIs), comparing those who have a copper-bearing (Cu-) or levonorgestrel (LNG-) intrauterine device (IUD) placed with women who do not. We searched PubMed and Cochrane Library for articles from January 1984 through January 2016 addressing our objective. We assessed study quality using the United States Preventive Services Task Force evidence grading system. Our search strategy yielded 2220 articles, of which 10 met inclusion criteria. Two studies provided direct evidence of PID rates in women with undiagnosed gonococcal or chlamydial (GC/CT) infection or at high risk for STIs initiating IUDs versus other contraceptive methods (level II-2, fair to poor), and neither study found a difference. Eight studies provided indirect evidence (II-2 to II-3, fair to poor). One study found no difference in PID rates between initiators of Cu- versus LNG-IUDs. Five studies compared algorithms based on patient factors with laboratory GC/CT screening to predict cervical infection. Based on likelihood ratios, none of these algorithms adequately identified women at high risk of asymptomatic cervical infection who should not undergo IUD placement. Two studies compared IUD placement on the same day as STI screening with delayed placement after screening and found no difference in PID rates. Limited evidence suggests that IUD placement does not increase the risk of PID compared with no IUD placement among women with asymptomatic undiagnosed cervical infection or at high risk of STIs. Algorithms based on patient characteristics to identify women with asymptomatic GC/CT may be overly restrictive, leading to missed opportunities for IUD initiation. Historical concerns about higher PID risk among women at risk for STIs who use IUDs may not be relevant with modern devices and STI screening and

Medical devices are regulated by the US Food and Drug Administration (FDA) within the Center for Devices and Radiological Health. Center for Devices and Radiological Health is responsible for protecting and promoting the public health by ensuring the safety, effectiveness, and quality of medical devices, ensuring the safety of radiation-emitting products, fostering innovation, and providing the public with accurate, science-based information about the products we oversee, throughout the total product life cycle. The FDA was granted the authority to regulate the manufacturing and marketing of medical devices in 1976. It does not regulate the practice of medicine. Devices are classified based on complexity and level of risk, and "pre-1976" devices were allowed to remain on the market after being classified without FDA review. Post-1976 devices of lower complexity and risk that are substantially equivalent to a marketed "predicate" device may be cleared through the 510(k) premarket notification process. Clinical data are typically not needed for 510(k) clearance. In contrast, higher-risk devices typically require premarket approval. Premarket approval applications must contain data demonstrating reasonable assurance of safety and efficacy, and this information typically includes clinical data. For novel devices that are not high risk, the de novo process allows FDA to simultaneously review and classify new devices. Devices that are not legally marketed are permitted to be used for clinical investigation purposes in the United States under the Investigational Device Exemptions regulation.

Full Text Available Exposure to prenatal inflammation is associated with diverse adverse neurobehavioral outcomes in exposed offspring. The mechanism by which inflammation negatively impacts the developing brain is poorly understood. Metabolomic profiling provides an opportunity to identify specific metabolites, and novel pathways, which may reveal mechanisms by which exposure to intrauterine inflammation promotes fetal and neonatal brain injury. Therefore, we investigated whether exposure to intrauterine inflammation altered the metabolome of the amniotic fluid, fetal and neonatal brain. Additionally, we explored whether changes in the metabolomic profile from exposure to prenatal inflammation occurs in a sex-specific manner in the neonatal brain.CD-1, timed pregnant mice received an intrauterine injection of lipopolysaccharide (50 μg/dam or saline on embryonic day 15. Six and 48 hours later mice were sacrificed and amniotic fluid, and fetal brains were collected (n = 8/group. Postnatal brains were collected on day of life 1 (n = 6/group/sex. Global biochemical profiles were determined using ultra performance liquid chromatography/tandem mass spectrometry (Metabolon Inc.. Statistical analyses were performed by comparing samples from lipopolysaccharide and saline treated animals at each time point. For the P1 brains, analyses were stratified by sex.Exposure to intrauterine inflammation induced unique, temporally regulated changes in the metabolic profiles of amniotic fluid, fetal brain and postnatal brain. Six hours after exposure to intrauterine inflammation, the amniotic fluid and the fetal brain metabolomes were dramatically altered with significant enhancements of amino acid and purine metabolites. The amniotic fluid had enhanced levels of several members of the (hypo xanthine pathway and this compound was validated as a potential biomarker. By 48 hours, the number of altered biochemicals in both the fetal brain and the amniotic fluid had declined, yet unique

Full Text Available Background. Understanding the factors associated with the use of hormonal and intrauterine contraception among HIV-infected men and women may lead to interventions that can help reduce high unintended pregnancy rates. Materials and Methods. This study is a subanalysis of a cross-sectional survey of 289 women and 241 men who were sexually active and HIV-infected and were attending HIV care visits in Lilongwe, Malawi. We estimated adjusted prevalence ratios (PRs to evaluate factors associated with hormonal and intrauterine contraceptive use for men and women in separate models. Results and Discussion. 39.8% of women and 33.2% of men (p=0.117 reported that they were using hormonal or intrauterine contraception at last intercourse. Having greater than 3 children was the only factor associated with hormonal and intrauterine contraceptive use among men. Among women, younger age, not wanting a pregnancy in 2 years, being with their partner for more than 4 years, and being able to make family planning decisions by themselves were associated with hormonal and intrauterine contraceptive use. Conclusions. The men and women in our study population differed in the factors associated with hormonal and intrauterine contraceptive use. Understanding these differences may help decrease unmet FP needs among HIV-infected men and women.

Metritis is a frequent problem in postpartum dairy cows. Intrauterine therapy with the antimicrobial oxytetracycline (OTC) is often used, although this therapy has not been shown to be superior to systemic therapy. The objectives of this study were to (1) determine the plasma and milk concentrations of OTC following intrauterine infusion in postpartum dairy cows with varying degrees of metritis severity; (2) determine the depletion time of OTC in an attempt to provide veterinarians withdrawal guidelines, should they use this therapy; and (3) correlate metritis severity scores with OTC concentrations in plasma and milk. Our hypothesis was that cows with more severe metritis would have higher OTC concentrations in milk following intrauterine therapy. Thirty-two cows were selected to participate in the study after farm personnel had determined that they had metritis based on evaluation of vaginal discharge between 4 and 14 DIM, in accordance with the farm's treatment protocols. Metritis scores (1-4) were assigned based on a published scheme: 1 represented yellow-to-orange thick discharge or translucent mucus with no fetid smell; 2 represented blood-tinged vaginal mucus, slightly watery, with little or no fetid smell; 3 represented red to red/brown watery discharge with moderate fetid smell; and 4 represented red to red/brown watery discharge containing pieces of placenta and an intense fetid smell. Trial cows received a single treatment of 4g of OTC (approximately 6.7mg/kg) via intrauterine infusion. Blood samples were collected over 96h, and milk samples were collected before intrauterine therapy and 3 times a day for 4 d following infusion. Following treatment, OTC rapidly diffused to plasma and subsequently to milk. Maximum OTC concentrations in plasma and milk occurred within the first 24h following intrauterine infusion, and 25 of the 32 cows had detectable OTC concentrations in milk at 4 d after intrauterine infusion. Cows with clinical metritis (metritis

Baron-Cohen's hypothesis that autism is caused by exposure to high intrauterine testosterone levels is considered in the context of (1) my hormonal hypothesis of sex ratio and (2) the notion of multifactorial inheritance. This yields the suggestions that (1) female cases of autism may be the product of (high genetic loading+moderate environmental exposure) and male cases of (high environmental exposure+moderate genetic loading), (2) one environmental agent is intrauterine testosterone and (3) the mother is the major source of that testosterone. These suggestions may help to explain most of the major established epidemiological risk factors for autism. These include various forms of pathology associated with psychological and/or physical stress. Stress of many sorts promotes the secretion of adrenal androgens in women. The three suggestions above may also explain some recently described features of autism including the psychological, behavioural and neuroanatomical differences between male and female cases.

Full Text Available BACKGROUND Abnormal uterine bleeding is one of the most frequent reasons for gynaecological consultation, occurring in approximately 30% of women of reproductive age. Menorrhagia by definition implies a menstrual blood loss equal to or greater than 80 mL. Many women seek consultation for bleeding episodes of less than this amount because of the stress associated with it. Most frequently used medications are combinations of prostaglandin synthetase inhibitors and antifibrinolytic drugs, nonsteroidal antiinflammatory drugs, oral progesterone like Norethisterone or medroxyprogesterone acetate and combined oral contraceptives. The usual treatment for women with menorrhagia not desiring further pregnancies and those not responding to medical managements is either hysterectomy or endometrial ablation. Endometrial ablation less commonly performed due to low success rate. Levonorgestrel intrauterine system (LNG-IUS is a new modality in the treatment of AUB. The objective of this study is to evaluate the use of Levonorgestrel intrauterine system as a treatment for women with menorrhagia. MATERIALS AND METHODS This is a prospective interventional comparative study conducted on women with abnormal uterine bleeding. The duration of study was from March 2012 to October 2013. The respondents include those outpatients attending Gynaecology Department of Government Medical College, Kottayam with menorrhagia. The samples size was 50 of which 25 were in experimental groups and remaining 25 in control group. Experimental group were given LNG IUS for menorrhagia and the remaining 25 patients were given oral progestins for heavy menstrual bleeding. In order to make a comparison of the impact of the two different kinds of interventions, the Hb level as well as the amount of blood loss were systematically estimated at frequent intervals. Accordingly, these measurements were carried for the said both groups at the commencement of research study and thereafter at an

Full Text Available The sources of development, homeostasis and metabolism habits, long-term effects on the health of infants delivered with intrauterine growth retardation are considered. Principals and aspects of nutrition choice for these particular infants as well as some controversial aspects on this topic are discussed. Research data represents nutrition of newborns and up to 3 months infants, including those with the IGR and moderate postnatal inanition, fed with goat milk based formula, containing pre- and probiotics.
Full Text Available Background: Approximately 5% of newborns were infected by hepatitis B virus (HBV via intrauterine transmission, but most of the infants born to HBV-positive mothers are protected from infection. However, the mechanisms by which intrauterine transmission is avoided remain elusive, and the roles of toll-like receptors (TLRs have been proposed. The aims of this study were to clarify if TLR 7 and 8 are involved in the prevention of intrauterine transmission of HBV. Methods: Real time polymerase-chain reaction (PCR was used to determine the expression of TLRs and cytokines in placenta and trophoblasts. The expression of MyD88 was interfered with small interfering RNA (siRNA in trophoblasts. An in intro model mimicking trophoblast barrier was established to evaluate the effect of MyD88 siRNA on HBV transmission across trophoblast barrier. Results: There were significant differences in placental expression of TLR7 (F=3.263, P=0.048 and TLR8 (F=3.257, P=0.048 among control (HBV-negative women, non-infected group (HBV-positive women whose infants were not infected and infected group (HBV-positive women whose infants were infected. The expression of TLR7 was significantly higher in non-infected group than infected group (P=0.039 and control (P=0.043. There was a significant difference in TLR8 expression between non-infected group and control (P=0.014, and the difference was close to but not significant (P=0.074 between non-infected and infected groups. Exposure of trophoblast to HBV significantly induced the expression of TLR7 (PConclusions: TLR7 and TLR8 on trophoblastic cells play an important role in the prevention of intrauterine HBV transmission by inhibiting HBV translocation across trophoblast.
Full Text Available OBJECTIVE: To compare the inflammatory response preserved ex vivo by decidual cells isolated from women who experienced preterm labor with and without subclinical intrauterine infection. METHODS: Fetal membranes were obtained after cesarean section from 35 women who delivered before 37 weeks of gestation following spontaneous preterm labor, with no clinical evidence of intrauterine infection. Decidua was microbiologically tested and cultured. Concentrations of anti-inflammatory cytokines (IL-2, IL-4, IL-10, pro-inflammatory cytokines (IL-6, IL-8, IL-1β and TNF-α, and matrix metalloproteinases (MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9 were measured in the supernatants using Bio-Plex, and prostaglandin E(2 (PGE(2 was measured by enzyme immunoassay. RESULTS: Subclinical infection was confirmed in 10 women (28.5%. Microorganisms isolated were Ureaplasma urealyticum (4, group B streptococci (3, Gardnerella vaginalis (1, and Escherichia coli (2. We found a significant increase of pro-inflammatory cytokines and a significant decrease of anti-inflammatory cytokines in supernatants from decidual cells obtained from women with preterm labor and subclinical intrauterine infection compared to women without infection. Secretion of MMP-1, MMP-8, MMP-9 and PGE(2 was significantly higher in infected women. Secretion of IL-8 by decidual cells from infected women persisted upon repeated in vitro culture passages. CONCLUSIONS: Almost 30% of idiopathic preterm labor cases were associated with subclinical intrauterine infection, and decidual cells isolated from these cases preserved an ex vivo inflammatory status after in vivo bacterial exposure.

Persistent endometritis in the mare is associated with hypersecretion of mucus by endometrial epithelium and migration of neutrophils into the uterine lumen. This study examines the relationships between N-acetylcysteine (NAC), a mucolytic agent with anti-inflammatory properties, and endometrial architecture, serum neutrophil function, post-breeding therapy, and reproductive performance of NAC-treated mares in a clinical setting. In study 1, endometrial biopsies from mares receiving intrauterine saline (fertile-control, n = 6) or 3.3% NAC (fertile-treatment, n = 6; barren-treatment, n = 10) were evaluated by histology and image analysis. In study 2, phagocytic activity of serum-derived neutrophils was measured after adding 0.5% or 3% NAC. In study 3, pregnancy rates of repeat breeders (n = 44) receiving an intrauterine infusion of 3.3% NAC 24-36 hours before mating (group 1) was recorded, as was first cycle of the season pregnancy rates of reproductively normal mares (group 2, n = 85), and mares treated for bacterial endometritis the cycle before mating (group 3, n = 25). Intrauterine NAC did not adversely affect endometrial histology. Extracellular mucus thickness and staining intensity were reduced in fertile-treatment mares (P NAC solution, but not by 0.5% NAC (P NAC was not irritating and inhibited the oxidative burst of neutrophils. Repeat breeder mares, with evidence of mucus hypersecretion, but no uterine pathogens, when treated with NAC followed by post-mating uterine lavage and oxytocin (and in some cases intrauterine antibiotics), achieved a pregnancy rate of 77%.

Full Text Available Background: Recurrent abortion is defined as three or moreconsecutive pregnancy losses. We aimed to determine the relationshipbetween male sperm parameters and hypo-osmoticswelling score and recurrent abortion. We also studiedwhether washing of spermatozoa and intrauterine inseminationin patients with recurrent miscarriage and low score hypoosmoticswelling test in male partners could improve the outcomeof pregnancy.Methods: Between February 2003 and September 2006 ingynecology clinics affiliated to Shiraz University of MedicalSciences, 176 women with a history of recurrent abortionand their male partners were selected as study group. And159 healthy and fertile couples without a history of recurrentabortion were selected as control group. The relationship betweenmale sperm parameters and hypo-osmotic swelling testand recurrent spontaneous abortion in their female partnerswas evaluated after intrauterine insemination for those withabnormal hypo-osmotic swelling test. Outcome of pregnancyin patients with recurrent abortion whose male partners hadlow score hypo-osmotic swelling test was evaluated afterintrauterine insemination.Results: Low scores of hypo-osmotic swelling test weremore frequently seen in the study group than the controls:116 (65% versus 24 (15%. The mean hypo-osmotic swellingscore was significantly lower in the study group(P< 0.001. The outcome of pregnancy improved after intrauterineinsemination in those with low score hypoosmoticswelling test. The pregnancy success rate in thetreated group (pregnant with intrauterine insemination was77.77% while in the untreated group (pregnant without intrauterineinsemination was 30.76% with a success rateratio of 2.04.Conclusion: There was a positive relationship between lowhypo-osmotic swelling test score in male partners and recurrentabortion in their wives. Intrauterine insemination improvedthe outcome of pregnancy in these couples.

Recently, we derived equations relating the flow of adult red blood cells through a placental arterio-venous anastomosis with intra-uterine and post-natal measured adult hemoglobin concentrations. In this letter, we re-derived the equations, now including a more realistic nonlinear decay of adult red blood cells, and re-evaluated the measurement accuracy of the arterio-venous flow and the lifetime of the red blood cells.

To describe changes in umbilical artery (UA) Doppler flow in monochorionic diamniotic (MCDA) twins affected by selective intrauterine growth restriction (sIUGR), to correlate Doppler findings with pregnancy course and perinatal outcome, and to report postnatal follow-up. This was a retrospective study of 140 MCDA twins with sIUGR. UA end-diastolic flow, defined as Doppler waveform pattern Type I (persistently positive), Type II (persistently absent or persistently reversed) or Type III (intermittently absent or intermittently reversed), was recorded at first examination and monitored weekly until double or single intrauterine fetal death (IUFD), bipolar cord coagulation or delivery. All neonates had an early neonatal brain scan, magnetic resonance imaging, when indicated, and neurological assessment during infancy. Rates (per 100 person-weeks) and hazard ratios (HR) of IUFD in the IUGR twin in each pregnancy were calculated considering UA Doppler pattern as a time-dependent variable. At first examination, there were 65 cases with UA Doppler waveform pattern Type I, 62 with Type II and 13 with Type III. Of the 65 Type-I cases, 48 (74%) remained stable, while 17 (26%) changed to either Type II absent (14%), Type II reversed (9%) or Type III (3%). Of 62 Type-II cases (47 with absent and 15 with reversed flow), 33 (53%) remained stable (18 with absent and all 15 with reversed flow). The 29 Type-II absent cases which changed became Type II reversed (24/47, 51%) or Type III (5/47, 11%). All 13 Type-III cases remained stable. Compared with Type I, the risk of IUFD (adjusted for estimated fetal weight discordance and amniotic fluid deepest vertical pocket) was highest when the pregnancy was or became Type II reversed (HR, 9.5; 95% CI, 2.7-32.7) or Type II absent (HR, 4.3; 95% CI, 1.3-14.3). Mild neurological impairment was more prevalent in the IUGR twin than in the large cotwin (7% vs 1%, P = 0.02). Risk stratification based on UA Doppler is useful for planning ultrasound

Aims To assess whether associations between maternal smoking during pregnancy and offspring smoking initiation are due to intrauterine mechanisms. Design Comparison of associations of maternal and partner smoking behaviour during pregnancy with offspring smoking initiation using partner smoking as a negative control (n = 6484) and a Mendelian randomization analysis (n = 1020), using a genetic variant in the mothers as a proxy for smoking cessation during pregnancy. Setting A longitudinal birth cohort in South West England. Participants Participants of the Avon Longitudinal Study of Parents and Children (ALSPAC). Measurements Smoking status during pregnancy was self-reported by mother and partner in questionnaires administered at pregnancy. Latent classes of offspring smoking initiation (non-smokers, experimenters, late-onset regular smokers and early-onset regular smokers) were previously developed from questionnaires administered at 14–16 years. A genetic variant, rs1051730, was genotyped in the mothers. Findings Both mother and partner smoking were similarly positively associated with offspring smoking initiation classes, even after adjustment for confounders. Odds ratios (OR) [95% confidence interval (CI)] for class membership compared with non-smokers were: experimenters: mother OR = 1.33 (95% CI = 1.06, 1.67), partner OR = 1.28 (95% CI = 1.06, 1.55), late-onset regular smokers: mother OR = 1.80 (95% CI = 1.43, 2.26), partner OR = 1.86 (95% CI = 1.52, 2.28) and early-onset regular smokers: mother OR = 2.89 (95% CI = 2.12, 3.94), partner OR = 2.50 (95% CI = 1.85, 3.37). There was no clear evidence for a dose–response effect of either mother or partner smoking heaviness on class membership. Maternal rs1051730 genotype was not clearly associated with offspring smoking initiation class in pre-pregnancy smokers (P = 0.35). Conclusion The association between smoking during pregnancy and offspring smoking

An adverse intrauterine programming occurs in diabetes and obesity as the consequence of an adverse maternal environment that affects the appropriate fetoplacental development and growth. Experimental models of diabetes and fat overfeeding have provided relevant tools to address putative mechanisms of the adverse intrauterine programming. The current knowledge far extends from the original thoughts of the resulting intrauterine programming of metabolic and cardiovascular diseases to a full range of alterations that affect multiple tissues, organs, and systems that will compromise the long-life health of the offspring. This review examines the postnatal effects of rodent models of mild diabetes and fat overfeeding, identifying the multiple organ derangements in the offspring resulting from mild maternal adverse conditions. In addition, the comparison of experimental models of severe diabetes and fat overfeeding and the crucial role of the placenta are discussed, providing an update of the actual scenario of the putative mechanisms and adverse consequences of maternal metabolic derangements.

Full Text Available Ureaplasma diversum is an opportunistic pathogen associated with uterine inflammation, impaired embryo implantation, infertility, abortions, premature birth of calves and neonatal pneumonia in cattle. It has been suggested that the intra-uterine infection by Ureaplasma diversum can cause vascular changes that hinder the success of pregnancy. Thus, the aim of this study was to evaluate the changes of intrauterine site of A/J mice in estrus or proestrus phase inoculated with Ureaplasma diversum. The infection was monitored at 24, 48 and 72 hours by the PCR methodology to detect the Ureaplasma in the inoculation site and the profile of circulating blood cells. Morphological changes, intensity of inflammation and the production of cytokines were compared. The infected mice showed local inflammation through the production of IFN-γ and TNF-α. Ureaplasma diversum infections in the reproductive tract of studied mice seemed to be associated with the production of pro-inflammatory cytokines in uterine parenchyma. The levels of TNF-α of infected mice were dependent on the bacterial load of inoculated Ureaplasma. Uterine experimental infections by Ureaplasma diversum have not been mentioned yet and herein we presented the first report of an intrauterine infection model in mice.

To examine the association between intrauterine growth and intelligence. Population based birth cohort study of sibling pairs born within a maximum of three years of each other. Mater-University women and children's hospital, Brisbane, Australia. 235 (470 children) sibling pairs. Among one randomly selected sibling from each pair verbal comprehension at age 5, general intelligence at age 14, and reading ability at age 14 increased linearly with increasing gestational age and sex standardised birth weight z scores. With adjustment for maternal age, race, and smoking during pregnancy, birth order, family income, and parental education the associations with verbal comprehension at age 5 and general intelligence at age 14 remained, whereas the association with reading ability at age 14 was attenuated to the null. Within sibling pairs, differences in intrauterine growth were positively associated with differences in verbal comprehension at age 5 (test score difference per one unit difference in birth weight z score = 1.52 (0.11 to 3.26)) and general intelligence at age 14 (1.09 (0.01 to 2.18)), but not with reading ability at age 14. Socioeconomic position or other fixed maternal characteristics do not seem to explain the positive association between intrauterine growth and childhood intelligence.
Full Text Available Aims: To investigate the therapeutic effects of bone marrow-derived mesenchymal stem cells (BMSCs transplantation on intrauterine adhesions (IUA. Methods: BMSCs were isolated and labeled by green fluorescence protein. IUA model was established by mechanical injury. 48 rats were randomly divided into control, IUA model, BMSCs vein injection and BMSCs intrauterine injection groups (n=12 in each group. The third generation of BMSCs was injected through tail vein or intrauterine. Three rats were killed at time 0 h, 7 d, 14 d and 28 d and bilateral uterus were obtained at each time points for the subseqent experiments. Morphological changes were determined by hematoxylin-eosin staining or Masson staining. Estrogen receptor (ER and progesterone receptor (PR were detected by immunohistochemistry. Results: BMSCs were specifically stained by CD44 and CD90, but not by CD45. Before treatment, the numbers of endometrial glands were significantly decreased, while fibrosis area rate was increased in IUA model group (PConclusion: BMSCs transplantation was effective to repair the damaged endometrium likely through promoting the ER and PR expressions.

Full Text Available Maternal starvation is a significant cause of intrauterine growth restriction (IUGR in the world and increases the risk of infection in the neonate. We examined the effect of maternal starvation on Toll like receptor (TLR4 expression in hepatic, splenic and intestinal tissues obtained from the adult IUGR offspring of prenatal calorie restricted rats. The hepatic TLR4 protein concentration was undetectable in the IUGR rats that had restricted milk intake during the suckling period (SM/SP; n = 4, p < 0.05 as compared to the normal growth controls (CM/CP; n=4, and access to ad lib milk intake during the sucking period partially corrected the hepatic TLR4 expression (SM/CP; n = 4. IUGR had no effect on the splenic (n = 4 or intestinal (n = 4 TLR4 mRNA levels. In the liver, IUGR led to a 20% increase in baseline tumor necrosis factor (TNF-α mRNA expression ( p < 0.03 and a 70% increase in interleukin-1β (IL-1β mRNA expression ( p < 0.008 as compared to the control rats (CM/CP; n = 7. LPS-induced hepatic TNF-α release was significantly higher in SM/SP as compared to CM/CP. We propose that IUGR dysregulates TLR4 expression and function in the offspring, which may help explain the increased risk of Gram-negative sepsis and inflammatory diseases in this population.

Ethnic minority women have a higher incidence of unintended pregnancy and abortion than Caucasian women, with significant individual and social implications. Post-abortion intrauterine contraceptive (IUC) use may reduce future unintended pregnancy. This was a retrospective review of 265 women undergoing abortion at a Los Angeles County Reproductive Options Clinic. Demographic factors, reproductive history, and post-abortion contraceptive choice were evaluated and analyzed. The population was predominantly Latina (73%) and single, with a mean age of 27. Immediate post-abortion IUC insertion was chosen by 48% overall and more frequently by Latinas (55%) than by African Americans (33%) or Asians (43%) (p = 0.02). IUC use increased with age, undesired future fertility, increasing gravidity, and history of previous abortion in univariate analysis. In multivariate analysis, IUC use increased with Latina ethnicity and increasing gravidity. In a clinic serving low-income urban women in Los Angeles, post-abortal IUC uptake is highest among Latinas and those with prior pregnancies. Future research should examine reasons for and barriers to IUC uptake in diverse communities and methods to improve post-abortion IUC uptake to prevent subsequent unintended pregnancies.

Growth-restricted fetuses are at risk for a variety of lifelong medical conditions. Preeclampsia, a life-threatening hypertensive disorder of pregnancy, is associated with fetuses who suffer from intrauterine growth restriction (IUGR). Recently, emerging evidence indicates that preeclamptic women harbor AT(1) receptor agonistic autoantibodies (AT(1)-AAs) that contribute to the disease features. However, the exact role of AT(1)-AAs in IUGR and the underlying mechanisms have not been identified. We report that these autoantibodies are present in the cord blood of women with preeclampsia and retain the ability to activate AT(1) receptors. Using an autoantibody-induced animal model of preeclampsia, we show that AT(1)-AAs cross the mouse placenta, enter fetal circulation, and lead to small fetuses with organ growth retardation. AT(1)-AAs also induce apoptosis in the placentas of pregnant mice, human villous explants, and human trophoblast cells. Finally, autoantibody-induced IUGR and placental apoptosis are diminished by either losartan or an autoantibody-neutralizing peptide. Thus, these studies identify AT(1)-AA as a novel causative factor of preeclampsia-associated IUGR and offer two possible underlying mechanisms: a direct detrimental effect on fetal development by crossing the placenta and entering fetal circulation, and indirectly through AT(1)-AA-induced placental damage. Our findings highlight AT(1)-AAs as important therapeutic targets.

Subfertility affects 15% of couples and represents the inability to conceive naturally following 12 months of regular unprotected sexual intercourse. Assisted reproduction refers to procedures involving the in vitro handling of both human gametes and represents a key option for many subfertile couples. Most women undergoing assisted reproduction treatment will reach the stage of embryo transfer (ET) but the proportion of embryos that successfully implant following ET has remained small since the mid-1990s. Human chorionic gonadotropin (hCG) is a hormone synthesised and released by the syncytiotrophoblast and has a fundamental role in embryo implantation and the early stages of pregnancy. Intrauterine administration of synthetic or natural hCG via an ET catheter during a mock procedure around the time of ET is a novel approach that has recently been suggested to improve the outcomes of assisted reproduction. To investigate whether the intrauterine administration of hCG around the time of ET improves the clinical outcomes in subfertile women undergoing assisted reproduction. We performed a comprehensive literature search of the Cochrane Gynaecology and Fertility Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, PsycINFO, registers of ongoing trials andreference lists of all included studies and relevant reviews (from inception to 10 November 2015), in consultation with the Cochrane Gynaecology and Fertility Group Trials Search Co-ordinator. We included all randomised controlled trials (RCTs) evaluating intrauterine administration of hCG around the time of ET in this review irrespective of language and country of origin. Two authors independently selected studies, assessed risk of bias, extracted data from studies and attempted to contact the authors where data were missing. We performed statistical analysis using Review Manager 5 in accordance with the Cochrane Handbook for Systematic Reviews of

Intrauterine growth restriction (IUGR) increases the risk for metabolic disease and diabetes, although the developmental origins of this remain unclear. We measured glucose metabolism during basal and insulin clamp periods in a fetal sheep model of placental insufficiency and IUGR. Compared with control fetuses (CON), fetuses with IUGR had increased basal glucose production rates and hepatic PEPCK and glucose-6-phosphatase expression, which were not suppressed by insulin. In contrast, insulin significantly increased peripheral glucose utilization rates in CON and IUGR fetuses. Insulin robustly activated AKT, GSK3β, and forkhead box class O (FOXO)1 in CON and IUGR fetal livers. IUGR livers, however, had increased basal FOXO1 phosphorylation, nuclear FOXO1 expression, and Jun NH2-terminal kinase activation during hyperinsulinemia. Expression of peroxisome proliferator–activated receptor γ coactivator 1α and hepatocyte nuclear factor-4α were increased in IUGR livers during basal and insulin periods. Cortisol and norepinephrine concentrations were positively correlated with glucose production rates. Isolated IUGR hepatocytes maintained increased glucose production in culture. In summary, fetal sheep with IUGR have increased hepatic glucose production, which is not suppressed by insulin despite insulin sensitivity for peripheral glucose utilization. These data are consistent with a novel mechanism involving persistent transcriptional activation in the liver that seems to be unique in the fetus with IUGR. PMID:22933111

Intrauterine growth retardation (IUGR) and postnatal nutrition are risk factors for adult metabolic syndrome. However, the influences of long-term high-fat diet (HFD) intake on ectopic fat deposition in non-adipose tissues in IUGR pigs remain unclear. The present study was to determine whether HFD consumption would enhance ectopic fat deposition in IUGR pigs. At day 28, IUGR and control pigs were fed ad libitum to either a regular diet or a HFD. Lipid store, enzymatic activities and mRNA expression of lipid metabolism-related factors in liver and semitendinosus muscle (SM) were quantified at postnatal day 178. Feeding a HFD to IUGR pigs but not to control pigs significantly increased daily weight gain, carcass fat mass, plasma leptin level and lipid content and lipoprotein lipase (LPL) activity and mRNA abundances of LPL and peroxisome proliferator-activated receptor gamma (PPARγ) in liver and SM, but decreased daily feed intake and mRNA expression of hormone-sensitive lipase (LIPE) and carnitine palmitoyl transferase-1 (CPT-1) in liver and SM (P IUGR pigs had a lower body weight but higher plasma levels of total cholesterol (TC) and insulin (P IUGR increased the vulnerability of HFD-fed pigs to ectopic fat deposition via enhanced fatty acid flux toward ectopic sites and reduced lipolysis and fatty acid oxidation.
Full Text Available Poor fetal growth, also known as intrauterine growth restriction (IUGR, is a worldwide health concern. IUGR is commonly associated with both an increased risk in perinatal mortality and a higher prevalence of developing chronic metabolic diseases later in life. Obesity, type 2 diabetes or metabolic syndrome could result from noxious "metabolic programming." In order to better understand early alterations involved in metabolic programming, we modeled IUGR rat pups through either prenatal exposure to synthetic glucocorticoid (dams infused with dexamethasone 100 µg/kg/day, DEX or prenatal undernutrition (dams feeding restricted to 30% of ad libitum intake, UN. Physiological (glucose and insulin tolerance, morphometric (automated tissue image analysis and transcriptomic (quantitative PCR approaches were combined during early life of these IUGR pups with a special focus on their endocrine pancreas and adipose tissue development. In the absence of catch-up growth before weaning, DEX and UN IUGR pups both presented basal hyperglycaemia, decreased glucose tolerance, and pancreatic islet atrophy. Other early metabolic defects were model-specific: DEX pups presented decreased insulin sensitivity whereas UN pups exhibited lowered glucose-induced insulin secretion and more marked alterations in gene expression of pancreatic islet and adipose tissue development regulators. In conclusion, these results show that before any catch-up growth, IUGR rats present early physiologic, morphologic and transcriptomic defects, which can be considered as initial mechanistic basis of metabolic programming.

A constitutive model for a fiber reinforced hyperelastic material was applied to understand arterial fiber remodeling in a sheep model of Intrauterine Growth Restriction (IUGR). IUGR is associated altered hemodynamics characterized by increased resistance to blood flow in the placenta and elevated fetal arterial pressure and pulsatility. The constitutive model describes the collagen contribution to the mechanics within the arterial wall in both control and IUGR carotid artery through defining the material modulus and the orientation of the microstructure. A sheep model of placental insufficiency induced IUGR (PI-IUGR) was created by exposure of the pregnant ewe to elevated ambient temperatures. Experimental data was collected using pressure-diameter measurements to measure passive compliance in control and PI-IUGR carotid arteries. The constitutive model was optimized to fit the experimental data predicting the material parameters. Specifically, the collagen fiber predicted angle (γ) in the control artery was 49.9° from the circumferential axis while the PI-IUGR was 16.6° with a 23.5% increase in fiber orientation (κ). Quantitative assessment of collagen fiber orientation in secondary harmonic generation images confirmed the shift in orientation between the two groups. Together these suggest vascular remodeling of the ECM fiber orientation plays a major role in arterial stiffening in the PI-IUGR near-term fetal sheep. Published by Elsevier Ltd.

Intrauterine Growth Retardation (IUGR) is defined as a rate of growth of a fetus that is less than normal for the growth potential of the fetus (for that particular gestational age). Small for Gestational Age (SGA) is defined infant born following IUGR, with a weight at birth below the 10th percentile.Suboptimal fetal growth occurring in IUGR fetuses is an important cause of perinatal mortality and morbidity. The acute neonatal consequences of IUGR include metabolic and hematological disturbances, and disrupted thermoregulation; in addition, respiratory distress (RDS), necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP) may contribute to perinatal morbidity. Metabolic disturbances are related to glucose and fatty acid metabolism. It is well-known that individuals who display poor growth in utero are at significantly increased risk for type 2 diabetes mellitus (T2DM), obesity, hypertension, dyslipidemia, and insulin resistance (the so-called metabolic syndrome, MS). MS ultimately leads to the premature development of cardiovascular diseases. In addition, short stature in children and adults, premature adrenarche, and the polycystic ovarian syndrome (PCOS) are endocrinological sequelae of IUGR. (8) Early onset growth delay and prematurity significantly increase the risk for neurological sequelae and motor and cognitive delay.Future prospective studies need to investigate risk factors for infants who are SGA. If reliable prediction can be achieved, there is potential to reduce future perinatal morbidity and mortality, and long term consequences among SGA babies.

Intrauterine growth-restricted (IUGR) fetal sheep, produced by placental insufficiency, have lower oxygen concentrations, higher lactate concentrations, and increased hepatic glucose production that is resistant to suppression by insulin. We hypothesized that increased lactate production in the IUGR fetus results from reduced glucose oxidation, during basal and maximal insulin-stimulated conditions, and is used to support glucose production. To test this, studies were performed in late-gestation control (CON) and IUGR fetal sheep under basal and hyperinsulinemic-clamp conditions. The basal glucose oxidation rate was similar and increased by 30–40% during insulin clamp in CON and IUGR fetuses (P IUGR fetuses during basal and insulin-clamp periods (P = 0.05). IUGR fetuses also had four-fold higher lactate concentrations (P IUGR fetal muscle and liver, mRNA expression of pyruvate dehydrogenase kinase (PDK4), an inhibitor of glucose oxidation, was increased over fourfold. In IUGR fetal liver, but not skeletal muscle, mRNA expression of lactate dehydrogenase A (LDHA) was increased nearly fivefold. Hepatic expression of the gluconeogenic genes, phosphoenolpyruvate carboxykinase (PCK)1, and PCK2, was correlated with expression of PDK4 and LDHA. Collectively, these in vivo and tissue data support limited capacity for glucose oxidation in the IUGR fetus via increased PDK4 in skeletal muscle and liver. We speculate that lactate production also is increased, which may supply carbon for glucose production in the IUGR fetal liver. PMID:26224688

To evaluate the effect of swimming in pregnant rats born with intrauterine growth restriction (IUGR) and their offspring, IUGR rats were obtained using the streptozotocin-induced severe diabetic (SD) rats. In this study, the nondiabetic parental generation presented 10 rats and diabetic parental generation presented 116 rats. Of these, the mated nondiabetic female rats were 10 and the number of diabetic rats was 45. In relation to term pregnancy, there were 10 animals in the nondiabetic group and 15 rats in the diabetic group. In the offspring of SD rats (IUGR group), 43 females were classified as small for pregnancy age, 19 rats were classified as appropriate for pregnancy age, and 0 female was classified as large for pregnancy age. The nondiabetic and SD pregnant rats generated offspring with appropriate (control [C]) and small (IUGR) weight for pregnancy age, respectively. At adult life, the C group was maintained as nonexercised C group and IUGR rats were distributed into 2 subgroups, namely, nonexercised (IUGR) and exercised (IUGRex). The rate of mated rats in the IUGR group was reduced compared to the C group. During pregnancy, the IUGR rats presented hyperinsulinemia, impaired reproductive outcomes, decreased body weight, hypertriglyceridemia, and hyperlactacidemia. The IUGRex presented reduced insulin and triglyceride levels. Thus, swimming improved lipid metabolism and increased insulin sensitivity. However, the offspring showed retarded growth, reinforcing the need to stimulate the exercise practice in women under supervision with different professional expertise to promote appropriate gestational conditions and improve perinatal outcomes. © The Author(s) 2015.

Full Text Available Recent studies have shown that infants with intrauterine growth restriction (IUGR undergo catch-up growth during infancy. The aim of our study was to evaluate the postnatal growth in a cohort of IUGR infants born in a tertiary-level Obstetric University Hospital of Northern Sardinia. An observational retrospective study was conducted on 12 IUGR (group A and 12 control infants (group B by measuring the anthropometric parameters of weight (W, length (L and head circumference (HC from birth to the 3rd postnatal year. At birth, significant differences were found between group A and group B with regard to all the auxological parameters (W, mean 1846.6 versus 3170.8 g, p < 0.0001; HC, 30.1 versus 34.4 cm, p < 0.0001; L, mean 43.4 versus 49.4 cm, p < 0.0001. During the 1st year, 8 of 12 (70% IUGR infants exhibited a significant catch-up growth in the 3 anthropometric parameters and a regular growth until the 3rd year of follow-up. The majority but not all infants born with IUGR in our series showed significant postnatal catch-up growth essentially during the first 12 months of life. An improved knowledge of the causes of IUGR will help to develop measures for its prevention and individualized treatment.

Intrauterine growth restriction (IUGR) is a condition which has been difficult to assess at an early stage, resulting in the delivery of children who have poor genetic growth potential. Currently, IUGR classification is based upon the system of ultrasound biometry. Doppler velocimetry allows the measurement of hemodynamic flow of major fetal vessels, comparing the flow indices and patterns of normal and IUGR cases. In this review, the effectiveness of Doppler velocimetry in assessing blood flow in major vessels including the umbilical artery, ductus venosus, and middle cerebral artery was studied for both diagnostic and prognostic screening of IUGR. The umbilical artery is the most frequently studied vessel in Doppler velocimetry due to its accessibility and the strength of its associations with fetal outcomes. Abnormalities in the ductus venosus waveform can be indicative of increased resistance in the right atrium due to placental abnormalities. The middle cerebral artery is the most studied fetal cerebral artery and can detect cerebral blood flow and direction, which is why these three vessels were selected to be examined in this context. A potential mathematical model could be developed to incorporate these Doppler measurements which are indicative of IUGR, in order to reduce perinatal mortality. The purpose of the proposed algorithm is to integrate Doppler velocimetry with biophysical profiling in order to determine the optimal timing of delivery, thus reducing the risks of adverse perinatal outcomes.

Intrauterine growth restriction (IUGR) decreases serum insulin growth factor-1 (IGF-1) levels. IGF-1 is an epigenetically regulated gene that has two promoters, alternative exon 5 splicing, and multiple termination sites. The regulation of gene expression involves the whole gene, as evidenced by the aforementioned IGF-1 paradigm. We hypothesized that IUGR in the rat would affect hepatic IGF-1 expression and alter the epigenetic characteristics of the IGF-1 gene along its length. IUGR was induced through a bilateral uterine artery ligation of the pregnant rat, a well-characterized model of IUGR. Pups from anesthesia and sham-operated dams were used as controls. Real-time RT-PCR and ELISA was used to measure expression at day of life (DOL) 0 and 21. Bisulfite sequencing and chromatin immunoprecipitation (ChIP) quantified IGF-1 epigenetic characteristics. A nontranscribed intergenic control was used for ChIP studies. IUGR decreased hepatic and serum IGF-1. Concurrently, IUGR modified epigenetic characteristics, particularly the histone code, along the length of the hepatic IGF-1 gene. Many changes persisted postnatally, and the postnatal effect of IUGR on the histone code was gender-specific. We conclude that IUGR modifies epigenetic characteristics of the rat hepatic IGF-1 gene along the length of the whole gene.
Full Text Available Intrauterine growth restriction (IUGR is an important perinatal syndrome that poses several serious short- and long-term effects. We studied cytokine production by maternal peripheral blood lymphocytes stimulated by trophoblast antigens. 36 women with a diagnosis of IUGR and 22 healthy women with normal fetal growth were inducted. Peripheral blood mononuclear cells were stimulated with trophoblast antigens and levels of the proinflammatory cytokines IL-6, IL-8, IL-12, IL-23, IFNγ, and TNFα and the anti-inflammatory cytokines IL-4, IL-10, and IL-13 were measured in culture supernatants by ELISA. IL-8 was produced at higher levels by blood cells of the IUGR group than normal pregnant women, while IL-13 was produced at lower levels. IL-8, IFNγ, and TNFα were higher in IUGR with placental insufficiency than in normal pregnancy. IL-12 levels were higher and IL-10 levels were lower in IUGR with placental insufficiency than in IUGR without placental insufficiency. We suggest that a stronger pro-inflammatory bias exists in IUGR as compared to normal pregnancy and in IUGR with placental insufficiency when compared to IUGR without placental insufficiency. Several ratios of proinflammatory to anti-inflammatory cytokines also support the existence of an inflammatory bias in IUGR.

Accumulating evidence reveals that intrauterine growth retardation (IUGR) can cause varying degrees of pulmonary arterial hypertension (PAH) later in life. Moreover, epigenetics plays an important role in the fetal origin of adult disease. The goal of this study was to investigate the role of epigenetics in the development of PAH following IUGR. The IUGR rats were established by maternal undernutrition during pregnancy. Pulmonary vascular endothelial cells (PVEC) were isolated from the rat lungs by magnetic-activated cell sorting (MACS). We investigated epigenetic regulation of the endothelin-1 (ET-1) gene in PVEC of 1-day and 6-week IUGR rats, and response of IUGR rats to hypoxia. The maternal nutrient restriction increased the histone acetylation and hypoxia inducible factor-1α (HIF-1α) binding levels in the ET-1 gene promoter of PVEC in IUGR newborn rats, and continued up to 6 weeks after birth. These epigenetic changes could result in an IUGR rat being highly sensitive to hypoxia later in life, causing more significant PAH or pulmonary vascular remodeling. These findings suggest that epigenetics is closely associated with the development of hypoxic PAH following IUGR, further providing a new insight for improved prevention and treatment of IUGR-related PAH.

Sotos syndrome is a childhood overgrowth syndrome characterized clinically by a distinctive facial gestalt, advanced bone age, childhood overgrowth, and non-progressive developmental delay; and genetically by haploinsufficiency of the Nuclear receptor binding SET Domain 1 (NSD1) gene. Generalized lymphedema has not previously been associated with Sotos syndrome. Generalized lymphedema has been associated with mutations in several genes including FLT4. This gene is involved in the regulation of VEGFR3, a key governor of lymphatic-endothelial cell development and function. We report on a 28-year-old Caucasian female with a de novo NSD1 intragenic mutation, c.5841_5848dup: p.Leu1950Serfs*22, who presented with characteristic clinical features of Sotos syndrome. Unusually this case includes atypical features of intrauterine growth retardation and post-pubertal onset of primary lymphedema. To our knowledge, no link between Sotos syndrome and generalized lymphedema has previously been described in the literature. We propose a mechanism by which disruptions in NSD1 gene may lead to generalized lymphedema. Aberrations of the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK)-signaling pathway has been identified in both Sotos syndrome and lymphedema. This finding extends the known phenotype of Sotos syndrome through the inclusion of lymphedema. This case also indicates that presence of low birth weight does not exclude the possibility of Sotos syndrome. © 2016 Wiley Periodicals, Inc.

Natural lymphocyte cytotoxicity of 99 pregnant women delivering intrauterine growth retarded (IUGR) babies was compared to that of 460 women with normal pregnancies. Lymphocytes separated from maternal blood were used as effectors in the in vitro cytotoxicity test using human embryonic fibroblast cells as target. The cytotoxicity test was based on the assessment of endogenous alkaline phosphatase activity of the target cells. A definite shift towards IUGR pregnancies was observed in the distribution of patients when analyzed according to step by step increase of lymphocyte cytotoxicity values. The incidence of increased cytotoxic activity (greater than or equal to 40%) was three times higher in the group of women with IUGR pregnancies than that in the control group. Within the group of women showing increased immunoreactivity during pregnancy the participation of IUGR pregnancies was 40.4%, while only 9.7% of the women with normal cytotoxicity belonged to the IUGR group. Combined analysis of ponderal indices and cytotoxicity values suggests that increased immunoreactivity is associated with a nutritive insufficiency resulting in the disproportionate form of IUGR.
Full Text Available Magnesium deficiency during pregnancy as a result of insufficient or low intake of magnesium is common in developing and developed countries. Previous reports have shown that intracellular magnesium of cord blood platelets is lower among small for gestational age (SGA groups than that of appropriate for gestational age (AGA groups, suggesting that intrauterine magnesium deficiency may result in SGA. Additionally, the risk of adult-onset diseases such as insulin resistance syndrome is greater among children whose mothers were malnourished during pregnancy, and who consequently had a low birth weight. In a number of animal models, poor nutrition during pregnancy leads to offspring that exhibit pathophysiological changes similar to human diseases. The offspring of pregnant rats fed a magensium restricted diet have developed hypermethylation in the hepatic 11β-hydroxysteroid dehydrogenase-2 promoter. These findings indicate that maternal magnesium deficiencies during pregnancy influence regulation of non-imprinted genes by altering the epigenetic regulation of gene expression, thereby inducing different metabolic phenotypes. Magnesium deficiency during pregnancy may be responsible for not only maternal and fetal nutritional problems, but also lifelong consequences that affect the offspring throughout their life. Epidemiological, clinical, and basic research on the effects of magnesium deficiency now indicates underlying mechanisms, especially epigenetic processes.
Full Text Available Background: Clomiphene citrate is one of the effective drugs for infertility treatment due to oligo-ovulation or anovulation. Intrauterine insemination (IUI is one of more adherent methods for treatment of infertile cases which is followed by controlled ovarian hyperstimulation (COH. Objective: the aim of this study was to evaluate Clomiphene citrate versus letrozole with gonadotropins in IUI cycles. Materials and Methods: In this prospective randomized trial, 180 infertile women who were referred to Milad Hospital were selected. The first group received 5 mg/day letrozole on day 3-7 of menstrual cycle. The second group received 100 mg/day Clomiphene in the same way as letrozole. In both groups, human menopausal gonadotropin was administered every day starting on day between 6-8 of cycle. Ovulation was triggered with urinary Human Chorionic Gonadotropin (5000 IU when have two follicles of ≥16 mm. IUI was performed 36 hr later. Results: The number of matured follicles, cycle cancellation, and abortion were the same in both groups. Endometrial thickness was higher at the time of human menopausal gonadotropin administration in letrozole group. Chemical and clinical pregnancy rates were much higher in letrozole group. Ovarian hyperstimulation was significantly higher in clomiphene group. Conclusion: Letrozole appears to be a good alternative to clomiphene citrate with fewer side effects.

Gestational diabetes mellitus (GDM) has been shown to be associated with a high risk of diabetes in offspring. In mitochondria, the inhibition of pyruvate dehydrogenase (PDH) activity by PDH phosphorylation is involved in the development of diabetes. We aimed to determine the role of PDH phosphorylation in the liver in GDM-induced offspring glucose intolerance. PDH phosphorylation was increased in lymphocytes from the umbilical cord blood of the GDM patients and in high glucose-treated hepatic cells. Both the male and female offspring from GDM mice had elevated liver weights and glucose intolerance. Further, PDH phosphorylation was increased in the livers of both the male and female offspring from GDM mice, and elevated acetylation may have contributed to this increased phosphorylation. We obtained lymphocytes from umbilical cord blood collected from both normal and GDM pregnant women. In addition, we obtained the offspring of streptozotocin-induced GDM female pregnant mice. The glucose tolerance test was performed to assess glucose tolerance in the offspring. Further, Western blotting was conducted to detect changes in protein levels. Intrauterine hyperglycemia induced offspring glucose intolerance by inhibiting PDH activity, along with increased PDH phosphorylation in the liver, and this effect might be mediated by enhanced mitochondrial protein acetylation.

This study was conducted to characterize pediatricians' current practice patterns and perceived barriers related to adolescent contraception counseling with an emphasis on intrauterine contraception (IUC). We performed a mailed survey study to 400 general pediatricians. Surveys were mailed to pediatricians at their individual office locations. General pediatricians belonging to the Massachusetts Pediatric Society were included in the study. The survey instrument assessed current practice patterns and perspectives as related to contraception counseling for adolescents. Use of contraception among adolescent patients, policy to recommend IUC to adolescents in various clinical scenarios, and barriers to adolescent contraceptive counseling. Over 50% of pediatricians considered abstinence their favored method of contraception for adolescents, while fewer than 20% reported discussing IUC as an option. Female pediatricians were more likely to discuss IUC (25% vs 8%, P = .01), as were younger pediatricians (28% vs 14%, P = .13). Given 8 clinical scenarios suitable for IUC use, less than 25% of pediatricians would offer IUC to a teen unless she had a history of a vaginal delivery or abortion. Seventy percent of pediatricians reported lack of training with IUC, and more than 30% reported legal, fertility and parental concerns as barriers to discussing IUC with adolescents. Efforts are warranted to improve the education of pediatricians regarding the most current guidelines for proper IUC use in adolescents with the goal to increase the frequency with which this effective contraceptive method is discussed with this vulnerable population.

Full Text Available Based on the spectral analysis of Doppler velocity waveform in uteroplacental and fetoplacental circulation, a Doppler parameters diagnostic efficiency was examined in fetus prenatal detection with intrauterine growth restriction (IUGR within Pregnancy Induced Hypertension (PIH and their respiratory menace.A prospective analysis was performed in 141 third-trimester pregnancies. The control group included 65 normal pregnancies and the expeimental group included 76 high-risk pregnancies, which was divided into three sub-groups, namely, 31 with IUGR within PIH, 24 with PIH only and 21 with IUGR only. The uterine artery was examined in uteroplacental circulation and umbilical artery was examined in fetoplacental circulation. Perinatal outcome and birth weight were recorded in each case.Uteroplacental circulation analysis showed statistically higer values of Pourcelot resistance index Ri in uterine artery in IUGR within PIH pregnancies. Statistically higher pulsatility index in umbilical artery was recorded in IUGR pregnancies compared to the control group and PIH subgroup. Higher values of pulsatility index were particulary noticed in IUGR within PIH subgroup. Doppler parameters in uteroplacental and fetoplacental circulation showed a significant negative correlation in relation to Apgar score of the newborn.In combination with biophysical profile and CTG, Doppler parameters diagnostic efficiency is increased on the evaluation of the fetus respiratory menace with IUGR and PIH.
Full Text Available Intrauterine growth retardation (IUGR leads to the dysfunction in digestive system, as well as the alteration in the expression of some functional proteins. Heat shock protein 70 (Hsp70 could be induced by various stress factors, but whether Hsp70 expression is changed in neonatal IUGR infants has not been demonstrated. This study was conducted to explore the expression of Hsp70 in the liver by using the IUGR piglet model. Liver and plasma samples were obtained from IUGR and normal birth weight (NBW piglets at birth. The neonatal IUGR piglets had significantly lower liver weight than their counterparts. The activities of aspartate aminotransferase and alanine aminotransferase in serum were enhanced significantly in IUGR indicating liver dysfunction. The activities of superoxide dismutase (p0.05 were lower and the level of malondialdehybe was higher (p<0.05 in IUGR liver compared with in NBW. According to the results of histological tests, fatty hepatic infiltrates and cytoplasmic vacuolization were present in the liver of IUGR piglets, but not in NBW liver. The expression of Hsp70 protein was significantly higher (p<0.05 in IUGR piglet liver than in NBW. Similar to where the hepatic injuries were observed, location of Hsp70 was mostly in the midzonal hepatic lobule indicating that oxidative stress might be responsible for the increased expression of Hsp70.
