Significant obstruction results if aortic valve area is less than 1 cm2 or if the nonpregnant mean gradient across the valve is above 50 mmHg. As the lines move further left, the more discriminating the test, with a higher sensitivity and low falsepositive rate. Thus, obstetric providers have responded in various ways to the apparently increased perinatal mortality and morbidity associated with postterm pregnancy. None of the seven cases had a deepest pool measurement of less than 2 cm, thus emphasizing the tradeoff between specificity and sensitivity. Endometrial ablation Antifibrinolytics and prostaglandin synthetase inhibitors are appropriate firstline treatments. Regimen 2 Start appropriate antibiotics promptly after making a clinical diagnosis. Levels of transferrin, the iron transporter protein, increase as it attempts to deliver more iron to tissues. Oestrogens have been shown to have beneficial effects on cardiovascular status in women. If the rearrangement is de novo, counseling is more challenging and the risk for developmental defects is estimated to be 6 percent. Similarly, a multiparous patient with secondary arrest should arouse suspicion, and Syntocinon augmentation should only be decided after careful clinical assessment of the patient by the obstetrician to exclude obstructed labour. Primary infertility refers to a woman who has never conceived whilst secondary infertility relates to any previous pregnancy irrespective of whether that resulted in a live birth or not. Prior to applying forceps, the blades should be assem bled to check whether they fit together as a pair. The find ings, plan of action and the procedure itself should be explained and the discussions carefully recorded. Similarly, by the time of clinically established hydrops, IgM levels may already be low or, rarely, undetectable. Glands of the endometrium pierce the myometrium and a single layer of columnar epithelium on the surface changes cyclically in response to the menstrual cycle. Both these conditions seem to be becoming less common than a more subtle loss of cerebral matter. Salpingo oophorectomy by transvaginal natural orifice transluminal endoscopic surgery. If close to term, delivery should be considered to improve maternal ventilation and markedly reduce oxygen requirements by removal of the fetoplacental unit. For many of the adverse effects, underlying disease in the mother (treated or not) may itself be associated with the adverse effect. For this reason labour should not be augmented in multi gravid patients with a confirmed brow presentation if progress is inadequate. Adequate contraception is important in women of reproductive age as transplacental passage of antiandrogens may disturb the genital development of a male fetus. Congenital anomalies associated with significant risk of cephalopelvic disproportion (including conjoined twins) would be an obvious indication and potentially monoamniotic twins would be another (see below). Additionally, conditions may be associated with stillbirth without directly causing them (wellcontrolled gestational diabetes and a cord event). A systematic review of randomized controlled trials to compare Bishop score with any other method for assessing preinduction cervical ripening in women admitted for induction of labour identified only two trials (both comparing transvaginal ultrasound with Bishop score) [14]. The ttest should be used when the population groups are assumed to be normal in distribution. Polycystic ovary syndrome Premature ovarian insufficiency Hyperprolactinaemia Weightrelated amenorrhoea Hypogonadotrophic hypogonadism Hypopituitarism Exerciserelated amenorrhoea 37% 24% 17% 10% 6% 4% 3% Secondary amenorrhoea Cessation of menstruation for six consecutive months in a woman who has previously had regular periods is the usual criterion for investigation. Thus, there is evidence that insulin resistance, central obesity and hyperandrogenaemia have an adverse effect on lipid metabolism, yet these are surrogate risk factors for cardiovascular disease. Pyrexia in labour is associated with an increased risk of fetal hypoxic damage and cerebral palsy [25,26]. There is no evidence that this is the case and therefore parents should be reassured that this is a local problem only.

Transvaginal ultrasonography is the primary diagnostic tool for clinically stable women with a suspected ectopic pregnancy [86]; of these patients, 73. There are major chromosomal abnormalities in just over 2% of infertile men, which is three times the normal incidence. The challenges of abnormal labour Infection the umbilical cord lies in random fashion around the fetus in utero and can wrap around or lie in close proximity to any part of the fetus so that during a contraction it can become squashed. Almost all women needing abortion care travel to Britain or Europe and there is evidence that many obtain medications online to induce their own abortions outside the legal framework [11]. The three layers run in complementary directions, encouraging vascular occlusion during contraction, an important aspect of menstrual blood loss and postpartum haemostasis. Time trends in multiple pregnancy demonstrate a remarkable change in reproductive behaviour and con sequence. So, for example, as screenpositive cutoff values are increased from the original 50 ng/mL to 200 and 500 ng/ mL, the positive predictive value for delivery within 14 days increases from 20% to 37% and 46%, respectively, whilst the negative predictive value only decreases from 98% to 97% and 96%. Babies who may be at risk of not making a successful adaptation without assistance include those in the following groups: preterm births (usually <36 weeks), those with known fetal complications, infants of diabetic mothers, fetal distress, fresh meconiumstained liquor, malpresentation and breech, multiple pregnancies, caesarean section under general anaesthesia or for fetal distress, risk of fetal infection and instrumental delivery. Neuronal intranuclear inclusions in a new cerebellar tremor/ataxia syndrome among fragile X carriers. For women with a previous caesarean section, or uterine scar from other surgery, there is limited evidence to help guide the management of induction of labour. Levels decrease rapidly in the post partum period, putting women at risk of postpartum haemorrhage. This appears to Role of Imaging in Gynaecology 513 be simply a reflection of the gestational age of the preg nancy; at early gestations the ectopic mass may simply be too small to visualize with ultrasound [89]. Presence of these features at imaging should discourage the clinician to select the patient for minimally invasive surgery with tissue morcellation in order to avoid the fragmentation and intraabdominal spread of malignant disease [29]. The usefulness of cerebral ultrasonography alone to predict neurological prognosis in extremely preterm infants is therefore limited. IgM antibodies are the first to appear after an acute infection (1 or 2 weeks before IgG). In general, this procedure is performed with a corecut biopsy needle inserted through a needle guide mounted on the transvaginal probe. Congenital toxoplasmosis is characterized by the tet rad of chorioretinitis, hydrocephalus, intracranial calcifi cation and convulsion. These children present already on maintenance therapy for other hormonal deficiencies and are hypogonadotrophic. When glucocorticoid steroids are required for lung maturation, insulin requirements over the following 72 hours may double. Poorly palpable landmarks are associated with placement difficulty, so ultrasound may be useful [13]. No particular subgroup of women in the highrisk group was substantially more or less likely to benefit from antiplatelet agents. To achieve this, women with pregestational diabetes ideally need to plan their pregnancies, be given preconception counselling and continue contraception until good glycaemic control has been achieved [26]. This is because the drugs will be cleared from the neonatal circulation rapidly, but the maternal antibodies will remain for approximately 3 months. Pregnancy tends to have a positive effect, with lower Creactive protein levels and improved digital plethysmography up to a year following delivery. Is there a difference in the behaviour and subsequent management of ectopic pregnancies seen at first scan compared to those ectopic pregnancies which commence as pregnancies of unknown location The accuracy of transvaginal ultrasonography for the diagnosis of ectopic pregnancy prior to surgery. For example, if two 12mg beclometa sone injections are given at 24hour intervals, either the insulin dose needs to be proactively increased or the woman admitted and a variablerate intravenous insulin infusion (previously termed insulin sliding scale) admin istered over the 72 hours, which can be given in addition to her normal insulin dose. Complications of adnexal masses An adnexal cyst in isolation may not cause pain and there are few data to tell us what size of cyst is significant in this respect. During pregnancy target blood pressure should be <140/90 mmHg, and in women with proteinuric renal disease ideally <130/80 mmHg but not less than 110/60 mmHg [19,20]. Depending on the location, consideration can also be given to supplementation with vitamin D.

Specific signs, such as angular cheilitis, glossitis and koilonychia, can occur in severe cases. Pregnancy should not alter the management of an acute stroke; pregnant women should be referred to stroke units and thrombolysis considered as with a nonpregnant patient [1]. Approach to the patient with suspected liver disease in pregnancy the presence of liver enlargement is always an abnormal finding in pregnancy, and hepatomegaly if identified may signify an infiltrative process ranging from acute fatty liver of pregnancy in the correct context to viral hepati tis, or even an infiltrative process such as lymphoma or cancer. The most severe form involves mitral and aortic valve atresia and an extremely hypoplastic left ventricle, with the degree of hypoplasia determining postnatal outcome. Historically, autonomic gastroparesis has been associ ated with poor pregnancy outcomes [65]. Moreover, due to a broad range of factors, because of subtle phenotypic changes, technical limitations and tissue differences, mosaicism is often undetected or undiagnosed. Renal Although glomerular capillary endotheliosis is a classic pathological feature of preeclampsia and relative oliguria is common in the early postpartum period, these features usually resolve spontaneously. Once the cervix is ripe, continuation of labour induction may involve forewater amniotomy (artificial rupture of the membranes) with or without augmentation of labour with oxytocin. In trying to reduce the impact of this morbidity, there are a number of principles which need to be applied in planning postnatal care. Uterine inertia with a lon gitudinal lying second twin is corrected by oxytocin infusion. If an ovarian mass is present, then a mature cystic teratoma is the commonest aetiology. It has to be remembered that the majority of women in the developing world do not use artificial contraception and rely on natural checks to their fertility. Antibiotics of any type, given prophylactically, do not reduce the incidence of perinatal death or neonatal encephalopathy and do not affect the rates of maternal sepsis or maternal death. Clinical awareness of the infection and what it might mean to fetal condition, fetal reserve and the likely tolerance of the fetus to the remaining labour will all play a part in timing the delivery. Functional characterization of prostaglandin transporter and terminal prostaglandin synthases during decidualization of human endometrial stromal cells. However, if the 5th centile is used, the baby lies outside the 95% confidence limit of what would be expected; similarly, the 3rd centile would make the baby even more likely to fall into the growthrestricted range as 97% of babies would be expected to be heavier. Severe postpartum episodes were more likely in women with previous postpartum psychosis compared to women with bipolar disorder (17%). Ultrasound of parental kidneys should be considered and genetic counselling offered. Asymptomatic bacteriuria is common, should be treated and, if recurrent, merits prophylactic antibiotics during pregnancy. Gynaecological procedures such as oophorectomy, hysterectomy and endometrial resection inevitably result in amenorrhoea. The essential role of the neonatologist in antenatal discussions is to ensure that a comprehensive plan for delivery (timing, mode and place) and clear plans for resuscitation and stabilization are in place. The changes in steroid hormone levels that occur immediately following delivery are not correlated with this transient depressive state, and because it is transient no therapy is needed. However, this requires more research and, at present, there is insufficient evidence to preclude treatment or fasttrack patients on the basis of an ovarian reserve test. Severe damage may cause demise of the fetus or, because of the pluri potent nature of the embryo and early fetus in general, compensatory changes may occur allowing development to continue in a normal or nearnormal fashion. One year later Jacobson and Barter2 performed the first prenatal diagnosis of a chromosomal abnormality. The fetal and neonatal brain is especially susceptible to injury between 20 and 34 weeks. This effect is particularly important when there is a family history of atopic illness [22]. Secondary antiphospholipid syndrome In the normal population, antiphospholipid antibodies are often transient and can be induced by a variety of factors. The gradient between colloid oncotic pressure and pulmo nary capillary wedge pressure is reduced by 28%, making pregnant women particularly susceptible to pulmonary oedema.

More specific oxytocin antagonists are in development, as are drugs which target other receptors, such as prostaglandin receptors. They should not be offered antioestrogens, gonadotrophins, androgens, bromocriptine or kininenhancing drugs because they have not been shown to be effective. A controlled trial of surgical induction of labour and amnioscopy in the management of prolonged pregnancy. It is well recognized that anxiety and depression during pregnancy increase the risk of anxiety and depression in the postnatal period. The assessment of endometrial pathology and tubal patency: a comparison between the use of ultrasonography and Xray hysterosalpingography for the investigation of infertility patients. It only refers to the lack of calcification of the nasal cartilage, making the nasal bone less echogenic than usual. It is costly and not appropriate for rare diseases with a long latent period for the development of the outcome of interest. There is an increased risk of postpartum haem orrhage, infection and thromboembolism so mothers should be closely monitored and attention paid to thromboprophylaxis. About onethird to half of complications occur during the setup phase, and onequarter are not recognized during the surgery, including more than half of bowel and ureteric injuries [71]. National, regional, and worldwide estimates of stillbirth rates in 2015, with trends from 2000: a systematic analysis. The BabyFriendly Initiative has adopted 10 successful steps to breastfeeding as its central strategy and these are outlined in Table 31. Type 1 diabetes Absolute insulin deficiency due to autoimmune destruction of the pancreatic cell. If investigations suggest that constitutional delay and development of secondary sexual characteristics is complete, there is no need to suggest any treatment other than annual review. Myomectomy Submucous fibroid(s) that are entirely within the cavity are classified as type 0. This may be due to inadequate preconceptual intake of folate and/ or poor compliance. The goals of managing such otherwise lowrisk pregnancies is to prevent the complications of postterm pregnancy and to the least invasive monitoring is maternal assessment of fetal movements, also known as fetal kick counts. Other possible causes of postmenopausal bleeding should be considered, such as cervical polyps, adnexal pathology and bladder pathology. Mechanisms of lactational amenorrhoea Breastfeeding may be associated with reduced juvenile onset diabetes mellitus [24] and neoplastic disease in childhood [25]. This can often be more effectively achieved by the mother rather than the physician. Are the risks higher of delivering at a given gestational age or of waiting an additional week of gestation For such comparisons, examining complications week by week is of more use than simply comparing before and after a given threshold. It also requires at least one healthy fallopian tube and reasonable sperm parameters. Detection of clinically significant atypical antibodies should prompt referral to a specialist fetal medicine unit for further investigation and management. Both are treated with dopamine agonists, and this typically results in a return to normal menstruation and fertility. Subsequently, only 29% demonstrated recurrent migraine on followup, suggesting that pregnancy can lower the threshold for a migraine. Thornton and Lilford [131] showed that pregnant women are much more risk averse than their caregivers. Increased incidence of glucose disorders during pregnancy is not 112 Maternal Medicine 8 9 10 11 12 13 14 15 16 17 18 19 20 21 explained by prepregnancy obesity in London, Canada.

Representational oligonucleotide microarray analysis: a high-resolution method to detect genome copy number variation. Cysts situated at the upper end of the vagina may be found to burrow deeply into the region of the broad ligament and the base of the bladder and should be approached surgically with considerable caution. While neonatal complications tend to increase as cord arterial pH falls [8], especially at values below 7. Over 90% of extremely preterm babies (<28 weeks) born in lowincome countries die within the first few days of life while less than 10% of babies born at this gestation die in highincome settings, a 10: 90 survival gap. The commonest of these, neonatal hypoglycaemia, is a consequence of persistent postnatal fetal hyperinsulinaemia when the maternal transfer of glucose has ceased. An increasing number of previous miscarriages also adversely affects the risk of future miscarriage [5]. Complete duplication of the uterus and cervix (uterus didelphys) is usually associated with a septate vagina. Most specimen bags are 10 or 15 cm in size, the former fitting through a 10mm port and the latter requiring a 12mm port. If the preference is for medical evacuation, then this may be more appropriately carried out in an inpatient setting. There is a loss of reality testing, with a compulsion to act on beliefs and an inability to recognize the consequences of their action, resulting in the increased risk of harm. Maternal Infection During Pregnancy 167 Clinical manifestations Maternal syphilis infection is staged according to dura tion and clinical features. The late adverse consequences of endometrial ablation are all relatively rare [55]. Additional long term problems include reflux, recurrent infections, bladder compliance and voiding issues and sexual function. On the other hand, there are a number of reported case series where removal of fibroids resulted in subsequent improved conception rates of between 30 and 80% [3]. Maternal obesity and consumption of a highfat diet during pregnancy can increase offspring vulnerability for mental or behavioural disturbances. Venous drainage is to the ovarian veins, which drain directly into the inferior vena cava on the right and into the renal vein on the left. Antenatal communication and care plans Anticipation and management of potential problems requiring specialist neonatal care is facilitated by multidisciplinary communication. In approximately 20% of females, pubic hair growth may precede breast development. These may include a loud first heart sound with exagger ated splitting of the second heart sound and a physiologi cal third heart sound at the apex. It aims to exert longitudinal lateral compression on the uterus combined with a tamponade effect and is performed by means of one long suture placed as illustrated in. It is essential to obtain an assessment of body fat, which is much more discriminatory. There are various entry techniques, the closed approach being most favoured by gynaecologists. It is now clear that the success of cervical cerclage depends on placing the suture as close to the internal os as possible. This is particularly important in developing countries, where it has been estimated that in each year there are 500 million cases of diarrhoea in infants and children and about 20 million of these are fatal. However, the latest systematic review has confirmed a significant increased perinatal risk associated with planned vaginal birth [6]. The process of cervical ripening involves changes in the connective tissue with an increase in collagen solubility and alterations in proteoglycans of the ground substance.

Temporary dialysis Temporary or acute dialysis has been advocated during pregnancy in the face of overall deterioration in renal function (especially when Surea exceeds 20 mmol/L and/ or there is refractory hyperkalaemia), severe metabolic acidosis, pulmonary oedema responding poorly to diuretics, and danger of volume overload with heart failure [5,31,39,44]. Occasionally, gradual resorption (autonephrectomy) of the abnormal kidney can occur. Oxytocin is required for nursing but is not essential for parturition or reproductive behavior. Diagnostic laparoscopy is a safe procedure with published complication rates of 2 per 1000 [65]. New perspectives into decidual function and the timing of birth have been presented, highlighting the complex interaction of biological factors (prostaglandins, cytokines, growth factors and reactive oxygen species), genetic predisposition and immune defence mechanisms in the regulation of human parturition [33]. It is not effective in women at risk who have a normal cervical Preterm Labour 401 length, nor has it been proven to be of benefit in multiple pregnancy, although there is some evidence that it may be beneficial in women with twins who also have a short cervix. In women with 2 cm or more of subcutaneous fat, suturing the subcutaneous space may reduce risk of wound infection, wound separation and haematoma or seroma formation. The fetal heart rate baseline is higher, averaging 155 bpm before 24 weeks compared with 140 bpm in a term fetus. The presence of viral infections, for example herpes simplex or condylomata acuminata, should alert the clinician to the possibility of sexual abuse. However, there is no evidence that tocolytic drugs confer this benefit and there is a real risk that to deliberately prolong a pregnancy, particularly in the context of chorioamnionitis, might lead to harm through retaining the fetus in an adverse intrauterine environment. A better way of preventing such postterm pregnancies would use techniques to encourage spontaneous labour. Initially, the larger, less muscular, umbilical vein obstructs resulting in decreased cardiac return, which stimulates baroreceptors that cause a tachycardia. Prediction of intrapartum fetal compromise using the cerebroumbilical ratio: a prospective observational study. Cryptic deletions are a common finding in "balanced" reciprocal and complex chromosome rearrangements: a study of 59 patients. It usually causes a mild thrombocytopenia in the third trimester with no symptoms of bruising or bleeding and no history of thrombocytopenia outside pregnancy. The lie will usually correct spontaneously before labour as uterine tone increases, although prolapse of the cord or arm is a significant risk if membranes rupture early. The presence of a partner or a relative may constrain discussion of domestic violence and could place the woman in greater danger. As such, it is important for clinicians to have an understanding of identification and treatment options for the most common disorders. Physiological changes are consistent with those associated with starvation and chronic illness. Cervical stenosis Cervical stenosis is an occasional cause of secondary amenorrhoea. If despite these measures angina, 88 Maternal Medicine pulmonary congestion and left ventricular failure persist or progress, balloon aortic valvotomy needs to be con sidered [13]. Adenomyosis may be present at one or more sites within the uterine wall or involve most of the myometrium, and may often be dispersed within the myometrium rather than forming a confined lesion, i. Blood group and red cell alloantibodies Identifying the maternal blood group and screening for the presence of atypical antibodies is important in the prevention of haemolytic disease, particularly from rhesus alloimmunization. Pregnancies in women with thalassaemia major and severe intermedia syndromes are high risk and should be managed in a multidisciplinary setting. Weight loss improves the endocrine profile, the likelihood of ovulation and a healthy pregnancy. Prevention centres on maternal vaccination during pregnancy and education to improve hygiene and change of local cultural practices. The normal autonomic responses of a healthy fetus to an episode of cord compression is the result of baroreceptor and chemoreceptor stimulation and proceed as follows. The laboratory cost for the additional bioinformatics analysis and reporting is minimal. Labour itself is therefore a marker of potential chorioamnionitis and so should not be inhibited. Passive management involves waiting for the three classic signs of placental separation (lengthening of the umbilical cord, a gush of blood from the vagina signifying separation of the placenta from the uterine wall, and a change in the shape of the uterine fundus from discoid to globular with elevation of the fundal height) before applying traction to the umbilical cord.

Recent estimates indicate that over 30 000 women die worldwide each year because of preeclampsia and its complications, with 98% of these occurring in developing countries [1]. The consequences of fetal growth restriction on brain structure and neurodevelopmental outcome. Besides adjusting the frequency, it is also important to change the focus of the ultrasound beam to optimize the resolution of the image at the depth of interest. Spontaneous fetal loss after demonstration of a live fetus in the first trimester. Auscultation for the fetal heart will confirm that the fetus is alive and can usually be detected from about 14 weeks of gestation. As these women may present directly to delivery suites, treatment protocols for an acute exacerbation of asthma and medical backup should be available. The Royal College of Anaesthetists suggests that more than 95% of elective and more than 85% of emergency cases should be performed under regional anaesthesia [20]. Following surgery, high dose oral oestrogens are initially prescribed followed by a 3month course of cyclical progesterone/oestrogens. Breastfeeding and breast cancer There is an epidemic of breast cancer among women in the developed countries of the Western world. The development of psychological problems after an abortion or a birth is most reliably predicted by a history of mental health problems. There is a risk of onset of panic disorder post partum and after weaning, which is hypothesized to occur due to fall in progesterone levels. Benzodiazepines are also effective, but have an increased risk of abuse and dependence. Therefore, for women who are worried about their declining fertility, it seems reasonable to let them make their own informed choice about earlier attempts to conceive. Research is progressing to find additional interventions to augment the benefit of hypothermia. Many women undergo transient physiological anxiety due to transition to parenting, but for some this may become pathological and continue for some time after delivery. Prenatal detection of aneuploidy by directly labeled multicolored probes and interphase fluorescence in situ hybridization. Parvovirus infection is an important cause of fetal anaemia, and should be considered in all cases of non immune hydrops. Importantly, there was only a small increased risk in preeclampsia that could be safely managed and no cases of uterine perforation or maternal death [17]. Management is frequently through simple means, with education and a sympathetic approach being essential. It varies with posture and if unaccompanied by any other abnormality reflects the increased stroke output. The term therefore includes all pregnancy losses from the time of conception until 24 weeks of gestation. In addition, there is an increased risk of hyperfiltration injury, which may be marked by hypertension and pro teinuria that warrants longterm surveillance. Clinical review: the benefits and harms of systemic testosterone therapy in postmenopausal women with normal adrenal function: a systematic review and meta analysis. Betamimetics (ritodrine, terbutaline, salbutamol) were among the earliest agents used clinically to inhibit uterine contractions, but their efficacy is questionable [110]. There is currently no consen sus on the factors that should be included in such a predictive model and no prospective validation or dem onstration of improved maternal and perinatal outcomes through application of such a test [90]. Age of the patient at examination Oncology center (referral center for gyn-oncol) Maximal diameter of the lesion Maximal diameter of the largest solid part More than 10 locules There are many causes of pelvic pain, many of which may be non gynaecological, and imaging findings taken in isolation may be misleading. In daily clinical practice, it may not be feasible to exclude all possible causes due to the additional cost implication. Other later symptoms include vomiting and abdominal pain whereas polydipsia and polyuria may also occur.

Torsion of the adnexae may occur when there is a mass in the ovary, but also in polycystic ovaries after fertility treatment or even in normal ovaries. Although entering the heart via the right atrium, this substrate and oxygenrich blood is Fetal Growth Restriction 227 (a) (b). Likewise there is no evidence to support the use of routine cardiotocography in uncomplicated pregnancies. When a recent primary infection is diagnosed, invasive testing can be offered to identify infected fetuses. Most infants who survive the neonatal period do well, although twothirds require pacemakers. Even in adults born preterm and who have no apparent medical problems, there are lower rates of highlevel education and higher rates of low income and dependence on social security benefits. Although vaginal delivery reduces the risk of haemorrhage, induction of labour often takes longer and prompt delivery can improve the maternal outcome. An endo metrial thickness of 4 mm or less decreases the likeli hood of endometrial cancer by a factor of ten, regardless of the use of hormone replacement therapy [35]. In a study from Dundee, Scotland, it was found that babies who had been breastfed for at least 3 months had greatly reduced incidences of vomiting and diarrhoea compared with babies who were either bottlefed from birth or completely weaned within a short time of delivery [19]. The blood is released, but its discharge for some time later may inter fere with the application of a mould and skin graft. Such developments will hopefully minimize the increased maternal and perinatal risks that exist in such complex pregnancies. Primary syphilis is the initial stage and its characteristic lesion is an erosion called a chancre. The key diagnostic feature on the fourchamber view of the heart is the presence of a common atrioventricular valve. In view of these data, induction of labour in women with a previous caesarean section should be undertaken with caution and in an environment where uterine rupture can be rapidly diagnosed and treated if necessary. The same is true for betasympathomimetics, which are given with the aim of increasing the fetal heart rate. The majority of gynaecologists use rigid hysteroscopes because the image tends to be superior, the equipment is more robust and it can be sterilized. The amount of cervical expansion needed is related to gestational age, provider skill and the instruments being used. The Versapoint electrode can rapidly excise nonfundal grade 0 fibroids although retrieval down the narrow cervical canal, even under general anaesthesia, can be difficult. Pain relief should be prescribed and this may include administra tion of rectal diclofenac with consent. A Cochrane systematic review in 2014 concluded that there was no evidence of a beneficial effect [26] and a similar conclusion was reached in a Bayesian network metaanalysis [27]. Prenatal sex detection with endocervical smear: successful result utilizing Y-body fluorescence. The potential disadvantage of more dialysis is electrolyte imbalance, hence the need to scrutinize serum chemistries at all times. Oral aciclovir should be prescribed for pregnant women with chickenpox if they present within 24 hours of the onset of the rash. A single incision is made but the length is variable and depends on the size of the perineum and type of delivery. Such findings are in concordance with other studies demonstrating no efficacy [34,35], in which progesterone was administered as intra muscular 17hydroxyprogesterone caproate (250 mg). As mentioned at the start of this chapter, couples who want a child should be encouraged to discuss all the implications, including the harsh realities of maternal survival prospects. Previous recommendations Puberty and Its Disorders 551 to delay the induction of puberty until age 15 to maximize height attainment would seem unjustified. Subtelomeric rearrangements detected in patients with idiopathic mental retardation.

Indications for caesarean sections at 34 weeks among nulliparous women and differential composite maternal and neonatal morbidity. Fortunately, all these women were menstruating normally, subsequently conceived and have had babies [47]. Fetal cord blood sampling in the diagnosis and the treatment of fetal hyperthyroidism in the offsprings of a euthyroid mother producing thyroid stimulating immunoglobulins. Risk of postpartum relapse in 190 Maternal Medicine bipolar disorder and postpartum psychosis: a systematic review and metaanalysis. Outcome measures should include vasomotor, urogenital, quality of life and psychosexual health and the longterm effect on cardiovascular, cog nitive and skeletal health. Dinoprostone tampon: obese women are twice as likely to require a second cervical ripening agent compared with nonobese women, and had labour lasting 5 hours longer. Measurement of cervical length is probably of better value in identifying women whose risk is more remote. Misoprostol is not licensed for use, can be stored at room temperature and costs significantly less. This observa tional study analysed over 23 000 nondiabetic pregnant women between 2000 and 2006 from nine countries. If the bladder is distended, it is usually palpable abdominally but if this is not the case or the clinician is uncertain of the abdominal findings, an ultrasound scan should be performed to determine the volume of urine retained in the bladder. Dyskeratosis congenita caused by a 3 deletion: germline and somatic mosaicism in a female carrier. This was followed by the Zahara I score which included the first three parameters but added the presence of valvular regurgitation, mecha nical valve prosthesis, cyanotic heart disease and cardiac medication required before pregnancy [9]. Respiratory infection Chest infections are not normally a serious problem in the puerperium, although recent outbreaks of potentially fatal influenza viruses have increased the level of concern. A hysteroscopic approach may still be valid in women who cannot undergo laparoscopic salpingectomy as there is no alternative, but there is no evidence to show benefit. There is incom plete division of the cerebral hemispheres with a single midline forebrain ventricle (monoventricle), which often communicates with a dorsal cyst. Hysterosalpingocontrast sonography and hysterosalpingofoam sonography the gold standard test to assess tubal patency is laparo scopic chromoperturbation with methylene blue. They are powerful for ceps requiring a skilled accoucheur who is willing to abandon the procedure if progress is not as expected. Highdose versus lowdose oxytocin infusion regimens for induction of labour at term. Investigations should be directed on the basis of a critical consideration of clinical features and used to inform patient management and counselling. In the longer term, there are concerns that accelerated weight gain may lead to increased risk of hypertension and other cardiovascular diseases as well as type 2 diabetes. This percentage has been rising since 2005, possibly due to greater accessibility of abortion services and acceptability of abortion as a means of fertility regulation. Cervical cerclage is most commonly performed using a braided Mersilene tape suture with needles on each end. Contrast, motion, perceptual integration, and neurocognition in schizophrenia: the role of fragile-X related mechanisms. These disorders may be inherited or acquired and severity of disorder varies (but the majority are mild to moderate). Pregnant women may present with atypical features as they often do outside of pregnancy. Women with congenital heart disease who have undergone corrective or palliative surgery in childhood and who have survived into adulthood are encountered more frequently. Because fewer babies than expected born to the women in the expectant management group developed neonatal sepsis, the trial was underpowered for this outcome; however, a subsequent metaanalysis of eight trials confirmed all Preterm Labour 403 these findings. There has been considerable debate regarding if or how the presence of secondary pathogenic changes discovered from whole exome or genome sequencing should be reported to a patient (see discussion below).

It is usually the first structure divided at hysterectomy, allowing the surgeon to open the overlying folds of peritoneum known as the broad ligament. Pregnant women on dialysis should be offered increased hours of dialysis, aiming for at least 24 hours per week. Written consent must be obtained for any invasive procedure on the baby, including tissues taken for genetic analysis. Diabetic neuropathy Diabetic neuropathy can manifest as either a periph eral sensory neuropathy or an autonomic neuropathy and both increase with duration of diabetes [64]. Approximately 80% of frozen blastocysts survive the Assisted Reproduction 715 thaw process and, depending on the age of the patient, one, two or three embryos are replaced. However, IgM can remain positive for months and even years, and interpretation of a positive result requires great caution. Death is usually preceded by vagal slowing, a fall in blood pressure and oxygen saturation, followed by ventricular fibrillation. Larger or fullthickness tears at the level of the internal os will usually require operative intervention or embolization. A recent study reported a greatly elevated 1year risk of suicide (mortality rate ratio of 289) in mothers with the onset of severe psychiatric illness within 90 days post partum relative to healthy mothers [29]. Inherited bleeding disorders During pregnancy, inherited bleeding disorders can increase the risk of maternal bleeding and, depending on inheritance, confer a neonatal bleeding risk [7]. This effect was independent of chorionicity (although there was a trend towards worsening of outcome in monochorionic twins). Most of the specific risks of hypertension in pregnancy appear to be related to superimposed preeclampsia (see Chapter 7). It used to be taught that the presentation of one before the other helped differentiate between ectopic and intrauterine preg nancy but it is clear that this is not the case. The blastocyst sheds the zona pellucida and then adheres to the endometrial epithelium, beginning the process of implantation. Further work is being conducted to con firm the efficacy and safety of this preparation but for the moment its use is restricted to specialist centres. Complications include haemorrhage, urinary tract damage, anaestheticrelated complications, infection and venous thrombosis. One trial demonstrated a decreased need for uterine reevacuation for incomplete abortion among women who received misoprostol for cervical preparation as compared to a placebo (0. Other anatomical anomalies Fusion anomalies Fusion anomalies of various kinds are not uncommon. Parental chromosomal abnormalities Parental chromosomal abnormalities are found in about 2% of women with recurrent pregnancy loss, with the most common being a balanced reciprocal translocation [14]. Preconception, prenatal, and preimplantation genetic diagnosis has heralded the now extant golden era of human genetics. Observations and height and weight (to determine body mass index) are routine, with cardiac, pulmonary, abdominal, pelvic or other examinations undertaken as needed. Prenatal diagnosis of autosomal recessive polycystic kidney disease by molecular genetic analysis. At present, it is medically possible to identify affected pregnancy in the antenatal period, and pregnancy termination of affected pregnancies is legal in many countries. These muscles support the pelvic organs, holding them in position and resisting the forces created when the intraperitoneal pressure is raised as in coughing or straining. The options are between intermittent auscultation (directly using a Pinard stethoscope or a handheld Doppler device) or continuous electronic recording via an abdominal Doppler transducer or fetal scalp electrode. Individuals with active hepati this are at greatest risk for developing cirrhosis and hepa tocellular carcinoma. The situation with triplets has been more contro versial, with many considering this a social issue for parents. Prostaglandins of the E and F series are present in high concentrations in the endometrium, and their synthesis is regulated by the ovarian steroids.
