In these women, renal sonography is recommended to search for obstruction, which is manifest by abnormal ureteral or pyelocaliceal dilatation (Seidman, 1998). Adrenergic-Receptor Blocking Agents Peripherally acting -adrenergic-receptor blockers cause a generalized decline in sympathetic tone and decreased cardiac output. In a study of 16,334 deliveries, Shaw and coworkers (2014) identified a significant association between posttraumatic stress disorder and spontaneous preterm delivery. This may be due to the sudden release of pituitary gonadotropin in amounts greater than usual during the first spontaneous cycle after stopping hormonal contraception. They compared two 3-year epochs- one before and one after 2011-and the results are shown in Table 43-2. Following mucocutaneous infection, the virus moves retrograde along sensory nerves. Whites have a higher incidence, and other autoimmune diseases are frequent in affected women (Shornick, 1984, 1992). It is important that shock from causes other than adrenocortical insufficiency-for example, hemorrhage or sepsis-be recognized and treated promptly. Examples are preterm or growth-restricted fetuses or those with macrocephaly from hydrocephaly. Reported prevalence rates range from 1 in 22,000 to 1 in 100,000 pregnancies (Dolapcioglu, 2009). Mitral Insufficiency A trivial degree of mitral insufficiency is found in most normal patients. These include G vaginalis, Fusobacterium species, Mycoplasma hominis, and U urealyticum. J Perinat Med 34(4):323, 2006 Garabedian C, Deruelle P: Delivery (timing, route, peripartum glycemic control) in women with gestational diabetes mellitus. Pregnancy Complications in 440 Women with Hypothyroidism Fetal and Neonatal Effects. Hurst and colleagues (2014) surveyed 1769 respondents of the Ehlers-Danlos National Foundation and found a preterm birth rate of 25 percent and infertility rate of 44 percent. Ironically, overdose is manifest by increased weakness-cholinergic crisis-that may be difficult to differentiate from myasthenic symptoms. These are the most common reason for admission for headache evaluation and management. Kemthong and colleagues (2016) studied 1073 women and 2146 controls and found that hemoglobin E trait does not increase pregnancy risks other than asymptomatic bacteriuria. With sustained pulmonary hypertension, extensive atherosclerosis and calcification often develop in the large pulmonary arteries. The incidence has been cited as being as high as 1 in 3000 births in Norway (Lekarev, 2011). Another shunting procedure is placement of an endoscopic third ventriculostomy for hydrocephalus (de Ribaupierre, 2007). New York, McGraw-Hill Education, 2017 Yinon Y, Mazkereth R, Rosentzweig N, et al: Growth restriction as a determinant of outcome in preterm discordant twins. She was given prophylactic treatment with plasma-derived factor X, which raised her plasma levels to 37 percent. The most frequent types of ovarian masses are corpus luteum cysts, endometriomas, benign cystadenomas, and mature cystic teratomas. Barriers include difficulties with access to care, personal perception of depression, and societal stigmata (Flynn, 2010; Smith, 2008). Almost 85 percent of coliform isolates from the more recent cohort were resistant to ampicillin. For example, pyelonephritis complicating pregnancy caused by Escherichia coli and Klebsiella species commonly is associated with bacteremia and sepsis syndrome (Cunningham, 1987; Snyder, 2013). Similarly, a Cochrane review concluded that evidence is insufficient for firm recommendations regarding thromboprophylaxis during pregnancy (Bain, 2014).
Early and aggressive thyroxine replacement is critical for newborns with congenital hypothyroidism. The disproportion between the rates at which plasma and erythrocytes are added to the maternal circulation is greatest during the second trimester. To limit the latter, a delay of 3 months after breastfeeding cessation will more reliably ensure complete breast involution. If this is not feasible, then attempts are made to reduce the number of medications used and to use them at the lowest effective dose (Patel, 2016). I, January 2016a American College of Obstetricians and Gynecologists: Practice advisory on low-dose aspirin and prevention of preeclampsia: updated recommendations. Much is known about the cell cycle based on in vitro (literally, "in glass") studies. The importance of antenatal vitamins and trace metals is further discussed in Chapter 9 (p. Pregestational diabetes also raises the birth defect rate, and gestational diabetes is complicated by excessive numbers of large-for-gestationalage and macrosomic fetuses (Chap. These are the number of placental masses, thickness of the membrane dividing the sacs, presence of an intervening membrane, and fetal gender (Emery, 2015). With a history of iodine-induced anaphylaxis, lithium carbonate, 300 mg every 6 hours, is given instead. Positive end-expiratory pressure is usually successful in decreasing the shunt by recruiting collapsed alveoli. Headache is the most frequent presenting symptom, neurological deficits are common, and up to a third of patients have convulsions (Wasay, 2008). Teleologically, this seems appropriate because the decidua intuitively should be a critical area to prevent coagulation that might lead to intervillous space thrombosis. Neonatal infection, especially in its early stages, may be difficult to diagnose because these newborns often fail to express classic clinical signs. Increases in pulse rate much above 100 beats per minute (bpm) or respiratory rate above 24 per minute, particularly when associated with dyspnea, may suggest impending ventricular failure. In nutritionally deprived countries, where infectious disease and malnutrition are primary causes of infant death, the World Health Organization (2016) recommends exclusive breastfeeding during the first 6 to 12 months. Pregnancy Important obstetrical aspects of some -thalassemia syndromes depend on the number of gene deletions in a given woman. Because maternal leukocytosis alone is not a consistent finding, fever is the only reliable indicator for the diagnosis of chorioamnionitis. Without functional Hex-A, gangliosides accumulate within neurons in the brain and cause deterioration of the nervous system. One fatal fetal cerebral hemorrhage developed from maternal vitamin K deficiency secondary to prolonged vomiting due to band slippage that created a gastric outlet obstruction (Van Mieghem, 2008). Ahmad and coworkers (2001) reviewed 22 cases during pregnancy and cited a 50-percent mortality rate. Other reports cited a small rise in the incidence of placental abruption and previa, preterm rupture of membranes, and gestational diabetes (Getahun, 2006; Wang, 2014). Mattox and Goetzl (2005) report these accidents to be the leading cause of traumatic fetal deaths as well. These investigators, however, did find a threefold greater risk of placental abruption in these women. Hemodynamic Effects Abdominal insufflation for laparoscopy causes hemodynamic changes that are summarized in Table 46-3. Importantly, because F-series prostaglandins and ergonovine exacerbate asthma, these commonly used obstetrical drugs should be avoided if possible. General Guidelines for Obstetrical Interventions for Threatened and Imminent Periviable Delivery Mode of delivery represents another dilemma because cesarean delivery at the threshold of viability is controversial.
A decrease in amplitude or disappearance of peristaltic waves in the lower two thirds of the esophagus is seen using manometry. Fetal cell microchimerism is the persistence of fetal cells in the maternal circulation and in organs following pregnancy. Clin Biochem 46(9):828, 2013 Haggar F, Pereira G, Preen D, et al: Maternal and neonatal outcomes in pregnancies following colorectal cancer. However, differences in populations of pregnant women studied, in definitions of preterm birth, and in data analysis may complicate interpretation of these data. For given filling pressures, there is appropriate cardiac output so that cardiac function during pregnancy is eudynamic. Management of those who do become pregnant has recently been detailed by Broberg (2016) and is discussed in the next section. Some aspects of the more common inherited thrombophilias are summarized in Table 52-2. Previous blood transfusions and even pregnancy enhance the risk of graft rejection (Young, 2015). Patients are asymptomatic for years, but eventually pulmonary hypertension becomes severe enough to cause this shunting (Greutmann, 2015). In some instances, a woman may present without symptoms but describes recent sexual contact with a person who has been diagnosed with syphilis. N Engl J Med 362(1):56, 2010 Abe S: An overview of pregnancy in women with underlying renal disease. Women who are athyreotic after thyroidectomy or radioiodine therapy may require higher doses. Although not teratogenic, its use in the second and third trimesters is associated with oligohydramnios, which appears to be reversible upon stopping the drug (Sarno, 2013; Zagouri, 2013b). Also, monochorionic twins have a significantly greater risk of spontaneous reduction than dichorionic twins (Sperling, 2006). Once you have determined the x2 value, you must then determine and interpret the p value for each ratio. Surg Gynecol Obstet 155:817, 1982 Ahmad A, Ahmed A, Patrizio P: Cystic fibrosis and fertility. We agree that changes in criteria are not justified until clinical trials prove benefits. Thus, advancing stages of the White classification, seen in Table 57-2, are inversely related to favorable pregnancy outcomes. Sheehan Syndrome Sheehan (1937) reported that pituitary ischemia and necrosis associated with obstetrical blood loss could result in hypopituitarism. Consisting primarily of microtubules, which are made of the protein tubulin, and microfilaments, which derive from the protein actin, this structural framework maintains cell shape, facilitates cell mobility, and anchors the various organelles. One evaluation compared prophylaxis during pregnancy with either sulfadoxine-pyrimethamine or dihydroartemisinin-piperaquine and found the latter to be more effective (Kakuru, 2016). N Engl J Med 356:1657, 2007 Gomi H, Goto Y, Laopaiboon M, et al: Routine blood cultures in the management of pyelonephritis in pregnancy for improving outcomes. Rates of shoulder dystocia vary greatly and can reach nearly 30 percent for macrosomic neonates when maternal diabetes is comorbid (Cordero, 2015). Importantly, cesarean delivery does not lower the risk of neonatal laryngeal papillomatosis. Several investigators describe a common pathway linking these suggested etiologies (Arany, 2016; Hilfiker-Kleiner, 2014). Vasa 45(2):103, 2016 Liu Y, Sun Y, Zhang S, et al: Placement of a retrievable inferior vena cava filter for deep venous thrombosis in term pregnancy. In their evaluation of several fetal vessels, Turan and associates (2008) described the sequence of changes characteristic of mild placental dysfunction, progressive placental dysfunction, and severe, early-onset placental dysfunction. Hypertensive disorders, including chronic hypertension and preeclampsia syndrome, accounted for 9. Amnionic fluid cytokines are most likely secreted by mononuclear phagocytes or neutrophils activated and recruited into the amnionic fluid.
Oxygen via nasal cannula may decrease the intensity of sickling at the capillary level. Pregnancy Acute nephritic syndromes during pregnancy can be difficult to differentiate from severe preeclampsia or eclampsia (Cabiddu, 2016). Both are associated with a lower risk of resistance than lamivudine (Ayres, 2014; Yi, 2016). That said, the contribution of these variants to the overall incidence of twinning is likely small (Hoekstra, 2008). The importance of cell-cycle control and these checkpoints can be demonstrated by considering what happens when this regulatory system is impaired. Although we have examined only genes with two alternative alleles, most genes have more than two allelic forms. That said, the incidence of rejection episodes approximates 2 to 5 percent (Bramham, 2013; Orihuela, 2016). Hydroxyurea is teratogenic in animals, although a preliminary 17-year surveillance of antenatally exposed children was reassuring (Ballas, 2009; Briggs, 2015; Italia, 2010). Assorted cardioembolic causes of stroke include arrhythmias-especially atrial fibrillation, valvular lesions, mitral valve prolapse, mural thrombus, infective endocarditis, and peripartum cardiomyopathy. Serum lipase activity is also increased and usually remains elevated with continued inflammation. For example, black women have disparately higher risks for preterm delivery (Grant, 2017). Obstet Gynecol 118:423, 2011 Meems M, Truijens S, Spek V, et al: Prevalence, course and determinants of carpal tunnel syndrome symptoms during pregnancy: a prospective study. Kruckenberg tumors are tumor-laden ovaries from another primary, often gastrointestinal, and have a bleak prognosis (Glisi, 2006; Kodama, 2016). Conversely, Lee and associates (2016) reviewed statistics from 74,725 deliveries in obese women and reported that elective induction at 37 to 39 weeks in nulliparas and especially multiparas was actually associated with a lower cesarean delivery rate. For the woman who becomes pregnant before these studies are performed, echocardiography is done. Specifically, in the newborns receiving betamethasone, rates of hypoglycemia were significantly greater (Gyamfi-Bannerman, 2016). Management of hepatitis A in pregnancy includes a balanced diet and diminished physical activity. Symptoms are nonspecific, and fever, weight loss, and malaise are present in more than half of cases. Found in 3 to 15 percent of select European populations and 3 percent of African Americans, it is virtually absent in African blacks and Asians (Lockwood, 2012). A high fetal death rate is attributable to preterm birth, congenital anomalies, twin-twin transfusion syndrome, or cord entanglement. In many ways, gestational hypertension is analogous to gestational diabetes in that such women have a chronic hypertensive diathesis, in which heredity and environment play a major role. Bloom and Leveno (2017) subsequently critiqued the use of transvaginal cervical length screening in low-risk women and the promulgation of consensus guidelines. Nulliparity, membranes extending beyond the external cervical os, and cerclage before 22 weeks were associated with a significantly decreased chance of significant pregnancy continuation. Medicine (Baltimore) 95(22):e3792, 2016 White P: Classification of obstetric diabetes. Up to 25 percent of diabetic gravidas have an early pregnancy loss (Galindo, 2006; Rosenn, 1994). Am J Obstet Gynecol 182:503, 2000 Castanon A, Brocklehurst P, Evans H, et al: Risk of preterm birth after treatment for cervical intraepithelial neoplasia among women attending colposcopy in England: retrospectiveprospective cohort study. Thromb Haemost 97:186, 2007 Bourjeily G, Khalil H, Raker C, et al: Outcomes of negative multidetector computed tomography with pulmonary angiography in pregnant women suspected of pulmonary embolism. Based on her review, Simpson (2012) recommends cesarean delivery for women with the following: (1) dilated aortic root >4 cm or aortic aneurysm; (2) acute severe congestive heart failure; (3) recent myocardial infarction; (4) severe symptomatic aortic stenosis; (5) warfarin administration within 2 weeks of delivery; and (6) need for emergency valve replacement immediately after delivery.
As perhaps expected, maternal and fetal survival parallels the percentage of burned surface area (Parikh, 2015). For example, a woman who has uncomplicated removal of an inflamed appendix may suffer aspiration of acidic gastric contents during tracheal intubation or extubation. In the 52 pregnancies resulting in a liveborn neonate, almost half were complicated by preterm delivery or hypertension. These changes translate to a cardiac output that enlarges across pregnancy to average 40 percent higher at term. Rupture is more likely in a previously scarred uterus and is usually associated with a direct impact of substantial force. Am J Psychiatry 163:2064, 2006 Yonemoto N, Dowswell T, Nagai S, et al: Schedules for home visits in early postpartum period. Birth Outcomes in 5405 Pregnant Women Undergoing Nonobstetrical Surgery Rates of fetal abnormalities with maternal surgery in early pregnancy do not appear increased. However, more than a fourth had at least one adverse cardiac symptom-including dyspnea, chest pain, or palpitations (Thaman, 2003). Importantly, preeclampsia developed in 60 percent, and 45 percent had preterm deliveries. Not only is their sensitivity still an issue in pregnancy, but these tests are not routinely available (Kashif, 2013; White, 2015). Semin Arthritis Rheum 39(4):285, 2010 Julkunen H, Kurki P, Kaaja R, et al: Isolated congenital heart block. Our current practices at Parkland Hospital are consistent with these recommendations. In their review of molecular mechanisms underlying diabetic embryopathy, Yang and colleagues (2015) suggest that these cellular responses to oxidative stress represent potential therapeutic targets to prevent diabetes-induced embryopathy. Only a few adults with primary immune thrombocytopenia recover spontaneously, and for those who do not, platelet counts usually range from 10,000 to 100,000/L (George, 2014). Reprod Toxicol 21:446, 2006 Ozturk Z, Tatliparmak A: Leprosy treatment during pregnancy and breastfeeding: a case report and brief review of literature. Obstet Gynecol 127(2):227, 2016 Siegel M: Congenital malformations following chickenpox, measles, mumps, and hepatitis: results of a cohort study. Risks were significantly higher among women who had a stillbirth or who underwent peripartum hysterectomy. For women who do not choose pregnancy, several reversible contraceptive methods are acceptable. This is eventually followed by left ventricular dilation and eccentric hypertrophy (see Table 49-6). Mechanistically, a "two-hit" hypothesis suggests that initial endothelial damage is then followed by intervillous placental thrombosis. The Society for Maternal-Fetal Medicine (2016b) has provided guidance for the performance of proper cervical length measurement. In developed countries, vesicovaginal or cervicovaginal fistula following a McDonald cerclage has been reported (Massengill, 2012; Zanconato, 2015). In sum, the American College of Obstetricians and Gynecologists (2016) recommends that antepartum testing be performed in multifetal gestations for indications similar to those for singleton fetuses (Chap. This practice reduced rates of delivery before 37 weeks from 79 to 51 percent in 67 women with twins. The incidence of chronic hypertension complicating pregnancy varies depending on population vicissitudes. The primary outcomes of neonatal death, chronic lung disease, and major cerebral abnormality were similar in both groups. Except in the rare situation of unremitting pain, surgery is rarely indicated, and most women remain asymptomatic during pregnancy.

In other cases, such as women with mechanical valves taking warfarin, fetal teratogenic concerns predominate. Although systemic sclerosis is incurable, treatment directed at end-organ involvement can sometimes relieve symptoms and improve function. No obvious benefits were gained for chronic lung disease, death in childhood, or neurodevelopmental delay in childhood. Consequent to the Lazarus study, however, clinical practice guidelines from the Endocrine Society, the American Thyroid Association, and the American Association of Clinical Endocrinologists uniformly recommended screening only those at greater risk during pregnancy (De Groot, 2012; Garber, 2012). Because treatment for less than 24 hours may be beneficial and reduce neonatal morbidity and mortality rates, a first dose of antenatal corticosteroids is administered regardless of the ability to complete additional doses before delivery (American College of Obstetricians and Gynecologists, 2017a). Despite these complications, Qidwai and associates (2006) reported a 70-percent vaginal delivery rate in women in whom myomas measured 10 cm. The national data are now reported starting with year 2007, which coincides with the year that this information became available. Anticoagulation and Abortion the treatment of deep-vein thrombosis with heparin does not preclude pregnancy termination by careful curettage. These factors in turn lead to impaired glucose tolerance and diabetes in adulthood. Trivedi and Gillett (1998) reviewed 45 case reports of asynchronous birth in multifetal gestations. Upper gastrointestinal endoscopy is used for management as well as diagnosis of several problems. Sonographic assessment of myocardial performance-the Tei index-in the first half of pregnancy has been evaluated. These problems were noted more frequently in those with higher total bile acid levels. Because regulations prohibited compounding, there was no competitor for this relatively inexpensive drug, and Makena was priced at $1500 per injection. Preventive Services Task Force recommends treatment with low-dose aspirin for chronically hypertensive women at high risk for preeclampsia (Henderson, 2014). Up to 20 percent of women with mild or moderate asthma have been reported to have an intrapartum exacerbation (Schatz, 2003). They also reported associations with central obesity, elevated systolic blood pressure, increased insulin resistance, and lipid abnormalities-all elements of the metabolic syndrome. Petri (2007) recommends pulse therapy consisting of methylprednisolone, 1000 mg given intravenously over 90 minutes daily for 3 days, then a return to maintenance doses if possible. In such women, if preeclampsia can be confidently excluded, it is reasonable to begin or to increase the dose of antihypertensive therapy. In premenopausal women, survival rates with this approach are improved, even if lymph nodes are cancer free. Am J Obstet Gynecol 177(1):149, 1997 Peitsidis P, Datta T, Pafilis I, et al: Bernard-Soulier syndrome in pregnancy: a systematic review. Vertical transmission (to the fetus/infant) and horizontal transmission (to peers) has been described (Trinks, 2014). Unless a special procedure such as umbilical cord interruption is used, selective termination should be performed only in multichorionic multifetal gestations to avoid damaging the surviving fetuses (Lewi, 2006). Inheritance of all four abnormal genes causes homozygous -thalassemia with predominant production of hemoglobin Bart, which has an appreciably increased affinity for oxygen. The causal effect of short interpregnancy intervals, however, has been questioned (Ball, 2014). It is controversial whether addition of an antiviral medication will add benefits (de Almeida, 2009; Gagyor, 2015; Quant, 2009). Prevention is by washing raw vegetables, cooking all raw food, and avoiding the implicated foods listed previously (American College of Obstetricians and Gynecologists, 2016d). The diagnosis can be made with confidence only after thrombosis and hemorrhage have been excluded and is more certain if an embolic source is identified.
Duncan (1980) reported an excessive incidence of low-birthweight newborns among infected women. Common causes of secondary or reactive thrombocytosis are iron deficiency, infection, inflammatory diseases, and malignant tumors (Deutsch, 2013). Despite the concept of brain sparing, growth-restricted infants had significantly smaller brains than controls. Other findings include edema, dry skin, hair loss, and prolonged relaxation phase of deep tendon reflexes. Mild-to- moderate degrees of stenosis are well tolerated, however, severe disease is lifethreatening. Hemolysis is characterized by a positive Coombs test, anemia, reticulocytosis, and unconjugated hyperbilirubinemia. The first and earliest is destruction-induced thyrotoxicosis with symptoms from excessive release of hormone from glandular disruption. Smith and colleagues (2003) reported an approximate incidence of 1 per 150,000 deliveries in the California Cancer Registry. Several of these inhibitors are found in lower concentrations in amnionic fluid from women with ruptured membranes. Surgical intervention is occasionally necessary and is accomplished by either lumboperitoneal shunting of spinal fluid or optic nerve sheath fenestration. Nahum and colleagues (1995) confirmed that fetal growth continues until at least 42 weeks. J Pediatr 151:450, 2007 Urquhart C, Currell R, Harlow F, et al: Home uterine monitoring for detecting preterm labour. The incidence is rising as measured by pregnancy-related hospitalizations for stroke (Callaghan, 2008; Kuklina, 2011). The second pedigree illustrates the pattern of inheritance for a trait such as Huntington disease, which is caused by an autosomal dominant allele. Diamnionic twins can become monoamnionic if the dividing membrane spontaneous or iatrogenically ruptures. Infections that most commonly cause sepsis syndrome in obstetrics are pyelonephritis (Chap. This is best seen when perinatal mortality rates are analyzed from times before widespread intervention for postterm pregnancies. The radionuclide dose should be kept as low as possible (Adelstein, 1999; Zanotti-Fregonara, 2017). In one study, 623 various procedures were performed in 2239 symptomatic pregnant women, but less than 2 percent required surgical exploration (Swartz, 2007). This provides a margin of safety in intravascular volume in anticipation of possible hemorrhage. Reasons at least partially responsible for adverse fetal consequences include decidual vasculopathy with placental infarction and decreased perfusion (Hanly, 1988). Several clinical studies support this practice (Bennett, 2004; Blondel, 2002; Joseph, 2007). In addition to his choice of a suitable organism, he restricted his examination to one or very few pairs of contrasting traits in each experiment. Dominitz (2002) reported a two- to threefold increased risk for preterm delivery, low birthweight, fetal growth restriction, and cesarean delivery in 149 women with Crohn disease. Fetal abnormalities and spontaneous miscarriage contribute to most losses (Prefumo, 2015). More recent reports describe better outcomes, but there still are serious complications. Westbrook and coworkers (2012) reported the outcomes of 81 pregnancies in 53 women. Up to 25 percent of affected women will be virilized, and of these affected women, nearly half of their female fetuses will have some degree of virilization. World J Surg 30:1603, 2006 Ueberrueck T, Koch A, Meyer L, et al: Ninety-four appendectomies for suspected acute appendicitis during pregnancy. Cases of moderately severe diarrhea with fecal leukocytes or gross blood may best be treated with empirical antibiotics rather than evaluation. Teratology 59:236, 1999 American College of Obstetricians and Gynecologists: Guidelines for diagnostic imaging during pregnancy and lactation. This foreign segment closely resembles sequences called transposable elements that have been discovered to have the ability to move from place to place in the genome of certain organisms.
Women referred to a behavioral health provider located at the same site as their obstetrical care are four times more likely to access treatment than those referred elsewhere (Smith, 2009). Delivery In the absence of a relaxed vaginal outlet, an episiotomy for delivery may be necessary once the fetal head reaches the perineum. With uncomplicated dichorionic multifetal gestations, use of antepartum surveillance has not improved perinatal outcomes. Because of these findings, umbilical artery Doppler velocimetry is considered standard in the evaluation and management of the growth-restricted fetus. Fetal infection develops in >50 percent of untreated early syphilis cases and in 10 percent of late latent disease (Fiumara, 1975; Hollier, 2001). Symptomatic enlargement of macroadenomas, however, is more frequent and was found in 21 percent of 238 pregnant women. The clinical syndrome begins with subtle signs of sepsis from infection and terminates with septic shock, which is defined by hypotension unresponsive to intravenous hydration. According to the postulate of dominance/recessiveness, combinations (2) and (3) will both yield tall plants. Importantly, 4 percent of mothers had died within a year after delivery, but this rate is comparable to that in nonpregnant liver transplantation patients. Methods of screening for the more common inherited thrombophilias are shown in Table 52-4. Both studies found the augmented cardiac output was predominantly due to greater stroke volume rather than higher heart rate. Still, almost 9 percent of pregnancies were complicated by adverse cardiac events including new-onset or worsening arrhythmias and heart failure (Balci, 2011; Kamiya, 2012). Moreover, it is associated with the development of resistant mutations and is no longer recommended at a first-line agent. Warming the delivery room and intravenous fluids, extra blankets, and socks and gloves are recommended to improve impaired circulation from Raynaud phenomenon. Am J Epidemiol 168(10):1145, 2008 Rudzinski E, Gilroy M, Newbill C, et al: Positive C4d immunostaining of placental villous syncytiotrophoblasts supports host-versus-graft rejection in villitis of unknown etiology. In the 28 women described by Martin and associates (2005), half died and most survivors had permanent disabilities. The Ann Arbor staging system, shown in Table 63-2, is applied to Hodgkin and other lymphomas. Arch Dermatol 120(4):511, 1984 Sitaru C, Powell J, Messer G, et al: Immunoblotting and enzyme-linked immunosorbent assay for the diagnosis of pemphigoid gestationis. Domestic abuse-another aforementioned risk factor for perinatal mood disorder-is also linked with adverse perinatal outcomes (Yost, 2005). Obstet Gynecol 119(3):626, 2012 Valentini P, Buonsenso D, Barone G, et al: Spiramycin/cotrimoxazole versus pyrimethamine/sulfonamide and spiramycin alone for the treatment of toxoplasmosis in pregnancy. Although the term peripartum cardiomyopathy has been used widely, at least until recently, little evidence supported a unique pregnancy-induced cardiomyopathy. They are ineffective for acute asthma and are used primarily to treat childhood asthma. Infants with major malformations, pregnancies complicated by stillbirth, and twin gestations with >25 percent discordance were also excluded. Perinatal outcomes were compared with those of 265 women also at 41 weeks randomly assigned to induction with or without cervical ripening. The peak appears as a triangular projection of placental tissue extending a short distance between the layers of the dividing membrane. Collateral circulation develops that carries portal blood to the systemic circulation. Medical management may be appropriate in asymptomatic pregnant women with mild hypercalcemia (Hirsch, 2015). Clin Appl Thromb Hemost 16(2):209, 2010 Maymon R, Strauss S, Vaknin Z, et al: Normal sonographic values of maternal spleen size throughout pregnancy. This leads to large cells with arrested nuclear maturation, whereas the cytoplasm matures more normally. Hyperparathyroidism in Pregnancy In their review, Schnatz and Thaxton (2005) found fewer than 200 reported cases of hyperparathyroidism complicating pregnancy. Despite this, ulcer disease may be underdiagnosed because of frequent treatment for reflux esophagitis (Mehta, 2010).
