If manual removal or expression of clots/placental fragments is unsuccessful women's health clinic flinders order provera 5mg free shipping, cervical dilation and curettage is indicated to remove retained fragments women's health clinic gosford proven provera 5 mg. The suture is placed from the lower end of the uterus to the top on both sides to assist in uterine compression menstrual girls photos best buy provera. If the fundus is boggy pregnancy stretches cheap provera 10 mg with mastercard, massage until it feels firm; it should feel like a large menstruation weight gain order provera without prescription, hard grapefruit. When massaging the fundus, keep one hand above the symphysis pubis to support the lower uterine segment, while gently but firmly rubbing the fundus, which may lose its tone when the massage is stopped. Explain that cramping or feeling like "labor is starting again" is expected with liberal administration of the oxytocic drugs used to manage the bleeding. Encourage the patient to void; a full bladder interferes with contractions and normal uterine involution. If the patient is unable to void on her own, a straight catheterization is necessary. Monitor vaginal bleeding; the lochia is usually dark red and should not saturate more than one perineal pad every 2 to 3 hours. Notify the physician if the bleeding is steady and bright red in the presence of a normal firm fundus; this usually indicates a laceration. Assist the patient and significant others as much as possible with newborn care to facilitate quality time between the mother and her newborn. Assist the patient with ambulation the first few times out of bed; syncope is common after a large blood loss. Intramuscular versus intravenous prophylactic oxytocin for postpartum hemorrhage after vaginal delivery: A randomized controlled study. Teach the patient how to check her own fundus and do a fundal massage; this is especially important for patients at risk who are discharged early from the hospital. Advise the patient to contact the physician for the following: a boggy uterus that does not become firm with massage, excessive bright red or dark red bleeding, many large clots, fever above 100. If iron supplements are provided, teach the patient to take the drug with orange juice and expect some constipation and dark-colored stools. If oxytocics are ordered, emphasize the importance of taking them around the clock as prescribed. If antibiotics are ordered, teach the patient to finish the prescription, even though the symptoms may have ceased. Although it is often present, edema is no longer included as a diagnostic criterion for preeclampsia because it is an expected occurrence in pregnancy and has not been shown to be discriminatory. If untreated (or sometimes even with aggressive treatment), the symptoms get progressively worse. Symptoms relate to decreased perfusion to the major organs: kidneys (proteinuria, oliguria), liver (epigastric pain, elevated enzymes), brain (headache, blurred vision, hyperreflexia, clonus, seizures) and the placenta (fetal distress, intrauterine growth restriction). Another complication can be disseminated intravascular coagulation, which is often fatal. Not only is preeclampsia life-threatening for the mother, but it can also cause intrauterine growth retardation, decreased fetal movement, chronic hypoxia, or even death in the fetus caused by decreased placental perfusion. If seizures occur, the patient has a risk for placental abruption, neurological deficits, aspiration pneumonia, pulmonary edema, cardiopulmonary arrest, acute renal failure, and death. Fetal bradycardia is typical during the seizure, usually with slow recovery to the baseline heart rate upon the seizure ending. Patients with proteinuria without hypertension initially have a higher incidence of progressing to preeclampsia than women with gestational hypertension. Immune maladaptation to paternal antigens associated with the fetus and placenta may lead to a situation similar to acute graft rejection. The brain, liver, kidney, and blood are particularly susceptible to multiple dysfunctions. Several risk factors have been identified that may predispose a woman to developing preeclampsia: maternal age; obesity; nulliparity; familial history; multiple gestation; patient history of diabetes mellitus, chronic hypertension, renal disease, urinary tract infection, trophoblastic disease, peridontal disease, and malnutrition. Bariatric surgery for obese women may decrease their chances of becoming preeclamptic. Obtain a thorough medical and obstetric history early in the pregnancy to determine if the patient has any of the risk factors. Ask the patient if she has noticed an increase in edema, especially in her face; nondependent edema is more significant than dependent edema. Question her about any nausea, headaches, visual disturbances (blurred, double, spots), or right upper quadrant pain. Common symptoms include hypertension, proteinuria, pitting edema, headache, and oliguria. Although most pregnant women experience some edema, it has a more abrupt onset in preeclampsia. Weigh the patient daily in the same clothes and at the same time to help estimate fluid retention; often, the patient gains several pounds in 1 week. A funduscopic inspection of the retina may reveal vascular constriction and narrowing of the small arteries. Check for clonus bilaterally by dorsiflexing the foot briskly and checking if the foot comes back and "taps" your hand. Count the beats of clonus present; presence of clonus is indicative of central nervous system involvement. Perform a sterile vaginal examination to determine if the patient is in labor or to determine the "ripeness" of her cervix for labor. Also note if the amniotic sac is intact or ruptured and if there is any bloody "show," which signals the onset of labor. If the amniotic sac is ruptured, note the color, amount, and presence of odor of the fluid. Assess the uterus for the presence of contractions, noting the frequency, duration, and intensity. Place the patient on the fetal monitor immediately to determine the status of the fetus. Provide ongoing assessments of the baseline fetal heart rate and of the presence or absence of variability, accelerations, and decelerations in the heart rate. Be alert for such signs and symptoms of impending eclampsia as accelerating hypertension, headache, epigastric pain, nausea, visual disturbances, and altered sensorium, and also increased bleeding tendencies. Many women expect pregnancy to be a happy and normal process; the hospitalization is unexpected. In addition to concern about the pregnancy, she may have other children or occupational responsibilities that need management while she is hospitalized. Assess the resources of the patient and significant others to manage job, child-care, financial, and social responsibilities. Serial laboratory tests are done to assist with diagnosis and monitoring of the disease. Increasing and decreasing trends indicate improvement or worsening of the disease state and help diagnose multiorgan involvement. If the fetus is premature, an amniocentesis may be done to obtain amniotic fluid for fetal lung maturity tests. If cerebral edema or intracranial bleeding is suspected, computed tomography scanning and magnetic resonance imaging are used. The goals of treatment are to prevent seizures, intracranial hemorrhage, and serious organ damage in the mother and to deliver a healthy term infant. The only cure for preeclampsia is delivery of the infant; however, if the infant is preterm, care is balanced between preventing maternal complications and allowing the fetus more time in utero. If the symptoms in preeclampsia are mild, often the patient is treated at home on bedrest, with careful instructions and education on the danger signs and frequent prenatal visits to monitor progression of the disorder. The patient should be instructed to remain on bedrest and to perform daily kick counts to monitor fetal well-being. Antihypertensives are usually not prescribed for mild preeclamptics; no differences in gestational age or birthweight have been noted, and growth-restricted infants were twice as frequent in mothers who took labetalol than in those treated with bedrest/hospitalization alone. If the urine output is below 30 mL per hour, suspect renal failure and notify the physician. Readings of 2 to 4 protein in the urine and urine-specific gravities of greater than 1. Hemodynamic monitoring with a central venous pressure catheter or a pulmonary artery catheter may be initiated to regulate fluid balance. Respiratory monitoring (respiratory rate, breath sounds) along with cardiac monitoring is important for ongoing assessments. Serum magnesium levels are done to determine if the level has reached the therapeutic level; serum levels also alert the caregiver of a move toward toxicity. If the magnesium sulfate infusion does not prevent seizure, the physician may order phenobarbital or benzodiazepines. Using either low doses of aspirin or dietary calcium supplementation is being explored as means to prevent preeclampsia. If the patient is alert and is not nauseated, a high-protein, moderate-sodium diet is appropriate. Glucocorticoids may be given to the mother intramuscularly at least 48 hours before delivery to assist in maturing fetal lungs to decrease the severity of respiratory difficulties in the preterm neonate. A cesarean section is indicated if the fetus is showing signs of distress or if preeclampsia is severe and the patient is not responding to aggressive treatment. Eliminate extraneous noises, lights, visitors, and interruptions that might precipitate a seizure. Pad the side rails and keep the bed in the low position with the call light in reach at all times. To be prepared for emergencies, keep a "toxemia kit," which includes an artificial airway, calcium gluconate (antidote for magnesium sulfate), syringes, alcohol pads, and other medications, at the bedside. If the patient is receiving magnesium sulfate, monitor for signs of magnesium toxicity: hyporeflexia, decreased respirations, and oliguria. If the patient is in labor, closely monitor fetal heart rate patterns and contractions. Because abruptio placentae is a potential complication of preeclampsia, be alert for any of the following signs of placental detachment: profuse vaginal bleeding, increased abdominal pain, and a rigid abdomen. The onset and severity of preeclampsia, along with its potential outcomes for the infant, are worrisome. After delivery, complications of preeclampsia can still manifest over the next 48 hours. The aim of this study was to determine if maternal infection or other exposures trigger the onset of preeclampsia. Researchers studied the window of 1 to 7 days before the diagnosis of preeclampsia, which is believed to be the highest risk period based on studies of infection and cardiovascular disease. Questionnaires were provided to women with singleton pregnancies and diagnosis of preeclampsia. There were no links among exercise, air travel, stress, and physical exercise and the onset of preeclampsia. The lack of evidence of triggers can be reassuring to women that preeclampsia is not likely to be related to something they did while pregnant. If the patient is discharged undelivered, emphasize that follow-up appointments are important for timely diagnosis of progressive preeclampsia. Tell the patient to notify the physician immediately for any of the following symptoms: headache; visual disturbance; right upper quadrant pain; change in level of consciousness or "feeling funny"; decreased urine output; increase in edema, especially facial; or any decrease in fetal movement. Tell the patient to weigh herself daily and notify the physician of a sudden weight gain. Be sure the patient understands the seriousness of the disorder and the potential complications to her and her infant. If the patient is discharged delivered, she needs to receive similar teaching because preeclampsia does not resolve immediately after delivery. The amniotic sac serves as a barrier to prevent bacteria from entering the uterus from the vagina; once the sac is broken, bacteria can move freely upward and cause infection in the mother and the fetus. It also occurs in 30% to 40% of preterm deliveries in the United States and Western Europe. Review the prenatal record if it is available or question the patient about problems with the pregnancy, such as high blood pressure, gestational diabetes, bleeding, premature labor, illnesses, and trauma. Determine the time the rupture occurred, the color of the fluid and the amount, and if there was an odor to the fluid. The most common sign is rupture of the membranes and gushing, leaking, or pooling of amniotic fluid. If bradycardia is noted, perform a sterile vaginal examination to check for an umbilical cord. If a cord is felt, place the patient in Trendelenburg position, maintain manual removal of the presenting part off of the umbilical cord, and notify the physician immediately. Perform a sterile vaginal examination if the patient is term (37 weeks) and note the dilation and effacement of the cervix and the station and presentation of the fetus. If the patient is preterm, notify the physician before doing a vaginal examination, which is often deferred in preterm patients to decrease the likelihood of introducing infection. A sterile speculum vaginal examination can be done to confirm rupture of the membranes. Pooling of amniotic fluid in the vagina or leakage from the cervix can be noted by the examiner (see Diagnostic Highlights for amniotic fluid analysis). Inspect the perineum and vaginal vault for presence of fluid, noting the color, consistency, and any foul odor. Normally, amniotic fluid is clear or sometimes bloodtinged with small white particles of vernix. Meconium-stained fluid, which results from the fetus passing stool in utero, can be stained from a light tan to thick green, resembling split pea soup. Palpate the uterus for tenderness, which is often present if infection is present. Healthcare providers may immediately induce labor or implement expectant management to allow the woman to begin labor naturally.

Despite this broad support from expert groups pregnancy nose provera 5 mg sale, studies show that prophylaxis is underused breast cancer chemo drugs buy 5mg provera. Major studies focusing on outpatient thromboprophylaxis for solid tumor or myeloma patients receiving systemic therapy are shown in Table 23 women's health clinic stephenville tx purchase discount provera online. One phase 2 trial randomizing 125 patients with advanced cancer receiving chemotherapy showed promise for apixaban in the prophylactic setting women's health center of jackson wy discount 10mg provera. No major bleeding incidents were reported with either a 5- or 10-mg dose of apixaban womens health 10k cheap generic provera canada, but two (63%) of 32 patients had a major bleed in the 20-mg group. Together, these studies demonstrate that outpatient thromboprophylaxis is feasible, safe, and effective. Three studies in the meta-analysis compared fixed-dose warfarin with no anticoagulation. Interestingly the rate of catheter-related events in more recent trials is 3% to 7%,139 compared with 24% to 39% in older trials48,49; differences may be due to variation among catheters or methods of catheter placement. At this time, evidence is insufficient to routinely recommend prophylaxis for all cancer patients with central catheters. Current guidelines recommend consideration of prophylactic anticoagulation for some high-risk groups, including patients with multiple myeloma receiving thalidomide or lenalidomide, patients with pancreatic or lung cancer, and patients deemed to be high risk by Khorana score. A meta-analysis by Akl and colleagues135 summarized the findings of nine of these studies encompassing approximately 2000 cancer patients with central catheters. However, only a small percentage of the patients in these studies had active cancer, and the comparator arm was warfarin, which is generally considered inferior for management of cancer-associated thrombosis. Many meta-analyses have been done incorporating cancer subgroup information from various trials. A recent prospective study was done at the Memorial Sloan Kettering Cancer Institute. Guidelines support continuing anticoagulation beyond 6 months in patients with active cancer and minimal bleeding risk. Further validation of this approach comes from a second randomized trial of rivaroxaban given 15 mg twice daily for 3 weeks, then 20 mg once daily for a total of 6 months compared to dalteparin as given in the edoxaban trial. However, in the absence of concurrent anticoagulant therapy, a high percentage of patients develop filter-related complications, including recurrent filterassociated thrombosis in up to 25% of patients. One of the first studies to investigate this was conducted by Zacharski and collegues,157 who studied the use of warfarin as an adjunct to chemotherapy in patients with small cell carcinoma of the lung. Since this landmark study, many other trials have investigated the benefits of anticoagulants as anticancer agents. A metaanalysis by Kuderer and colleagues158 summarized the results of many of these trials. There are many risk factors for cancer-associated thrombosis, and we are increasingly able to predict the risk of cancer-associated thrombosis through the use of risk prediction tools and biomarkers.

Recent breakthroughs in understanding the mechanisms of this remarkable and heterogeneous disorder lend confidence that we will be able to further reduce this stubborn and persistent mortality rate, both through treatment of the acute disease and the reduction in relapses. On postmortem examination, Moschcowitz found terminal arterioles and capillaries occluded by hyaline thrombi, without perivascular inflammation or endothelial desquamation. Moschcowitz posited that a "powerful poison which had both agglutinative and hemolytic properties"3,4 was the cause of this frightening new disease, now known as thrombotic thrombocytopenic purpura and sometimes called Moschcowitz disease in honor of its discoverer. In retrospect, many therapies used were reasonable, given what we now know about the autoimmune etiology of the most common acquired form. Such therapies included corticosteroids, immune suppressants, and often splenectomy. Later it was proposed that plasma exchange was superior to simple plasma infusion,7,8 and this was demonstrated in a randomized clinical trial. Discoveries over the past 4 to 5 decades have led to improved understanding of its cause, pathophysiology, and improved method of diagnosis and treatment, resulting in significant reductions in the morbidity and mortality of this disorder. More recently, these criteria have been narrowed to thrombocytopenia and microangiopathic hemolytic anemia in the absence of any other obvious cause for these findings, in part because these were the criteria used to define the disorder in the randomized clinical trial that established the superiority of plasma exchange over plasma infusion. Neurologic signs and symptoms are common at presentation and range in severity from headaches, confusion, and transient bizarre mentation to sensorimotor deficits, aphasia, seizures, and coma. Heart involvement may be asymptomatic or heralded by symptoms such as chest pain, syncope, dyspnea, or palpitations. Of the 41 patients, 27 had elevated plasma troponin T levels; those with the higher levels tended to have overt cardiac symptoms. Rhythm abnormalities could result in sudden death and could be caused by infarction of the myocardium or microvascular occlusions producing ischemia of the sinoatrial or atrioventricular node or the bundle of His or the Purkinje conduction system. Occasionally, schistocytes do not appear until one or several days after the initial clinical presentation. Note that several red blood cells (arrows) are schistocytes, which result from mechanical hemolysis. The acquired disorder is more common and, as with most autoimmune disorders, occurs more often in women than in men. It can be precipitated by a number of conditions including infections (especially viral;. Nevertheless, one study found that over three-fourths of cases had no obvious precipitating cause. Those with several recurrences experience them at irregular intervals, often commencing within the first year after the initial episode.

A meta-analysis of controlled trials of recombinant human activated protein C therapy in patients with sepsis menstrual extraction nyc cheap provera 10mg visa. The duration of anticoagulation is a frequent reason for consultation because it poses difficult questions of risk and benefit pregnancy week by week calendar cheap provera 5 mg fast delivery. Although the practical frustrations of anticoagulation to patients have been slightly mitigated by the arrival of alternatives to warfarin breast cancer slogans discount provera express, weighing the risks of bleeding compared with clotting remains as challenging as ever womens health group tulsa ok order provera with paypal. The use of hereditary thrombophilia testing to help better predict which patients will benefit from long-term anticoagulation held out great promise pregnancy signs and symptoms discount provera 5mg otc, but as detailed in this chapter, the practical applications are limited and nuanced. Unfortunately, results from thrombophilia testing have not resulted in more tailored management to reduce risk of recurrent thrombosis. Furthermore, inappropriate thrombophilia testing or misinterpretation of test results can cause harm through overtreatment or false reassurance. No study has conclusively proven a benefit or harm to thrombophilia testing, and an attempt to settle the question prospectively with a multicenter randomized control trial was terminated due to low enrollment. The role of thrombophilia testing in other clinical settings is discussed elsewhere (Chapters 15, 17, 20, 22, 23, and 33). Five to fifteen percent of patients recur in the first year if anticoagulation therapy is discontinued after 3 to 6 months. In fact, no statistical difference could be detected in major bleeding compared with placebo. However, the patients in the study were generally without significant risk factors for bleeding, and major bleeding was sufficiently rare that precise estimates of relative risk for major bleeding could not be made. Along the same lines, extended anticoagulation with prophylactic dosing of rivaroxaban (10 mg daily) appeared to be as effective as rivaroxaban 20 mg daily but had a major bleeding risk similar to a prophylaxis with 100 mg daily aspirin. Only a few years ago, it was held that laboratory testing for congenital thrombophilia would prove highly decisive; however, currently it is felt that the role of such thrombophilia testing is greatly outweighed by clinical factors as this power overwhelms the meager risk from genetic disorders. Accordingly, testing for hereditary thrombophilia is not recommended for these patients because the results will not change management. Because hereditary thrombophilia testing is unhelpful for this purpose, as discussed previously, other clinical and laboratory markers have been studied. Among the factors identified, d-dimer appears to have the best discriminatory power for identifying a lower risk group. Women with 0 to 1 criteria were deemed appropriate to discontinue anticoagulation after the initial 5- to 12-month treatment. However, it should be noted that this group was still at increased risk of recurrence. However, for patients with increased bleeding risk, a more nuanced assessment of risk to clot and risk to bleed is appropriate. Several scoring systems have been proposed for weighing the risk of bleeding while on therapeutic anticoagulation. All were validated in the warfarin era, contain similar risk factors, and none has proven clearly superior. This may be due to the fact that, like many traits, thrombophilia is influenced by a large number of polymorphisms, each having only a small independent effect. Thus the currently available testing does not account for all the risk of any one inherited thrombophilic condition. When considering genetic testing for hereditary thrombophilia, physicians should follow best practices regarding genetic testing. Informed consent discussion should include an understanding of the risks and benefits of both courses of action, as well as what risk modification tools are available. When counseling asymptomatic patients regarding the impact of hereditary thrombophilia, risks should be presented as absolute risks rather than relative risks. Other key elements of risk communication include using a consistent denominator. Thus lifelong prophylactic anticoagulation is almost never recommended to unaffected individuals, regardless of their genotype. Because testing should only be undertaken if it will result in a change in management, a strong case can be made that unaffected family members of patients with hereditary thrombophilia should not be screened. However, there may be periods of transiently amplified risk that theoretically might warrant prophylactic measures beyond those recommended to the average individual, and this is the argument cited for screening some individuals. Because thrombotic events are infrequent, benefits to prophylactic measures are difficult to capture and most recommendations are based on theoretical risk frameworks. Next we will review the evidence regarding the four most commonly discussed (but nevertheless controversial) situations in which this might be warranted: pregnancy, estrogen use, major surgery, and extended airplane flight (Table 14. Thus it is important when testing unaffected individuals that appropriate counseling be given to avoid unnecessary worry and overtreatment. These potential harms are difficult to quantify but must be considered when considering testing unaffected individuals (see Chapter 33). Estrogen Use Supplemental estrogen is associated with a dose-dependent increased risk of thrombosis,78 thought to be related to altered levels of clotting factors. There also appears to be a synergistic effect with hereditary thrombophilias, particularly factor V Leiden. However, patients may be prescribed combined oral contraceptives for noncontraceptive indications such as endometriosis. It is important to note that pregnancy itself is associated with a higher risk than combined oral contraception; therefore not taking or discontinuing combined oral contraception cannot be recommended if the alternative is an ineffective method of birth control (see Chapter 31). However, depot progesterone implants do appear to increase risk twofold to threefold through an unclear mechanism. Thus compression stockings can be recommended in lieu of pharmacologic prophylaxis in unaffected individuals. Frequent ambulation might have the same effect based on current understanding of the pathophysiology of airplane-associated thrombosis, but this has not been rigorously tested. Although immobility appears to be the primary risk factor for thrombosis in this setting, there are unique aspects of airplane travel that are not fully understood because the risks are higher in airplane flights than in similar-length bus rides,101 and markers of coagulation activation are higher in 8-hour airplane flights than in 8-hour movie marathons. However, the patient likely would be faced with some amount of stress from this, even if adequate counseling is provided. More than 100 heterozygotes would be identified for every 1 homozygote for whom an intervention would be recommended. One risk:benefit analysis of testing for factor V Leiden to improve pregnancy outcomes showed small potential improvements in quality-adjusted lifeyears, but sensitivity analyses indicated a large variance in results due to data uncertainty. There is a tendency to see genetic information as more definitive than other forms of testing. Approximately 79% of patients incorrectly estimated the magnitude of thrombosis risk associated with their diagnosis of factor V Leiden. Forty-three percent of patients reported that knowledge of factor V Leiden status increased their worry. Homozygous type 1 deficiency has not been described and is embryonically lethal in mice. This produces a conformational change that may affect both heparin and thrombin binding. These assays involve a synthetic chromogenic substrate of thrombin/ factor Xa that upon cleavage has strong light absorption at a specific frequency that can be monitored by spectrophotometer. The original assay was susceptible to warfarin effect, but second-generation assays mix with normal plasma to negate this effect. However, they will not affect functional assays that use snake venom to activate protein C and a chromogenic substrate to measure enzymatic activity. Note that free protein S antigen is the preferred first line test for protein S deficiency, not the functional assay. Protein C deficiency is autosomal dominant, and rare homozygotes may present with neonatal purpura fulminans. Testing First line testing is a functional assay that will detect most subtypes of protein C deficiency. There are two types of functional assays for protein C deficiency, clot based and chromogenic. Both tests use the venom from the southern copperhead snake, which activates protein C. For these reasons, chromogenic protein C activity testing is preferred if available. A chromogenic synthetic substrate for protein C is added which when cleaved can be detected by spectrophotometry. Heterozygotes typically have levels between 35% and 65% of normal; therefore 65% is a commonly used cutoff for adults. However, there is overlap between individuals with an inherited defect and normal individuals with borderline low protein C levels. In addition, there is day-to-day variation in levels, and some individuals with a mutation may have levels within the normal range. Protein C levels are significantly lower in neonates (17% to 53%),156 increase throughout childhood, and may not reach final adult levels until age 25 to 30. Protein C levels are significantly lower in neonates (17% to 53%),156 Protein C Deficiency Background Discovered in 1981, protein C deficiency was the second hereditary thrombophilia to be characterized. Protein C, when activated, is a serine protease with the primary function to prevent clot extension into areas of intact endothelium. On the surface of intact endothelial cells is thrombomodulin, which binds thrombin, thus altering the function of thrombin, promoting its cleavage of protein C to form activated protein C. Protein C is localized to the region of thrombomodulin on the surface of endothelial cells by the endothelial protein C receptor. Although these complexities are also seen with functional assays of protein C, the additional challenge is the sensitivity of the assay to preanalytic variables. Falsely low values can be seen in up to 10% to 15% of normal individuals through an unclear mechanism. For these reasons the preferred testing for protein S deficiency is a quantitative test. Free protein S represents the true functional fraction of circulating protein S and is recommended as the first line test. However, total protein S levels should not be tested in isolation, because even extremely low total protein S levels correlate poorly with venous thrombosis. Protein S Deficiency Background Protein S deficiency was first characterized in 1984. Protein S deficiency is autosomal dominant, and rare homozygotes may present with neonatal purpura fulminans. Arginine 506 is the normal initial cleavage site in factor V for activated protein C, and a mutation at this site leads to slower inactivation of factor Va and thus prolonged thrombin generation. Other rare mutations in the factor V gene have been described that can also lead to activated protein C resistance. Although genetic testing for factor V Leiden will not detect other mutations in the factor V gene that can also lead to activated protein C resistance,213-217 these are sufficiently rare that routine testing for factor V Leiden alone is typically satisfactory. This effect does not cause bleeding in vivo because phospholipid is abundant in the blood stream on the surface of platelets and endothelial cells. However, these variables should not be neutralized with the addition of phospholipid. A concurrent mixing study is recommended to be performed to exclude the presence of a factor deficiency. Therefore this may support resuming anticoagulation, even in the setting of increased bleeding risk (see "weighing bleeding risk" earlier). The Leiden Thrombophilia Study, using a case-control design similarly found increased association with thrombosis with "double-positive" and "triple-positive" individuals. Levels steadily increase throughout pregnancy, from 120% to 140% of normal in the first two trimesters to an average of 210% in the peripartum period. Furthermore, the 90th percentile differs between populations, and the assays for detecting elevated levels are not well standardized, making it difficult to extrapolate study results into clinical practice. Besides the monetary benefits, the initiative reduced misleading and thus potentially harmful testing, such as protein C and protein S testing while on warfarin therapy, as well as genetic testing in patients not adequately counseled beforehand. Advocating for guideline-based decision support in the electronic medical record has been shown to be effective in reducing inappropriate testing in a number of settings. Basic liver function testing might reveal primary or metastatic disease in the hepatobiliary system. Colonoscopy should be performed for all patients older than 50 years, if not performed recently.
