It is important to spasms kidney area purchase 50mg imitrex conclude this in-depth discussion of the immune-mediated mechanisms of isolated and recurrent pregnancy loss by suggesting that pregnancy may not require an intact maternal immune system back spasms 38 weeks pregnant order genuine imitrex. Supporting this concept are data showing that agammaglobulinemic animals and women can successfully reproduce (282) muscle relaxant 25mg buy imitrex 50mg without prescription. Still xanax muscle relaxant dosage purchase imitrex 50mg visa, immune fac to spasms esophageal buy 25mg imitrex with amex rs may play important roles in a significant proportion of patients with recurrent pregnancy loss, and their presence is the subject of abundant research. Until this role is better defined, an understanding of contemporary immunologic hypotheses fosters the informed consideration of novel findings. Male Fac to rs Most publications that review testing and treatment for recurrent pregnancy loss couples, including this chapter, recommend only a single test for the male partner in the couple—a peripheral blood karyotype. The role of the male partner in the etiology of recurrent pregnancy loss is understudied, but there is a growing body of literature suggesting that the development and validation of novel testing and treatment regimens for the male may prove beneficial (283,284). Detailed peripheral chromosomal testing of men whose partners experienced recurrent pregnancy loss revealed an increased incidence of Y chromosome microdeletions when compared to male partners in fertile and infertile couples (285). Small studies demonstrated that male partners in couples experiencing recurrent pregnancy loss have an increased incidence of sperm chromosomal aneuploidy, particularly sex chromosome disomy, when compared to fertile men (16,286). The latter results suggest that these men may have abnormal levels of reactive oxygen species in their semen or that their sperm cells are particularly sensitive to these compounds. Other Fac to rs It is increasingly evident that the implantation of the blas to cyst within the uterine decidua involves an exquisitely scripted crosstalk between embryo and mother. Alterations in this dialogue often result in improper implantation and placental development. Cellular and extracellular matrix adhesion properties may also be involved in this dialogue. The concept of uterine receptivity has been emboldened by the description of endometrial integrins and the timing of integrin switching during implantation (292). Others have reported decreased levels of endometrial mucin secretion and reductions in the endometrial release of soluble intercellular adhesion molecule I among women with his to ries of recurrent pregnancy loss (293,294). Programmed cell death (apop to sis) may also play an essential role in normal placental development. Alterations in two important apop to tic pathways—Fas-Fas ligand and bcl2—have both been linked to recurrent pregnancy loss and poor pregnancy outcome (121,295). Environmental Fac to rs A variety of environmental fac to rs have been linked to sporadic and recurrent early spontaneous pregnancy loss. These are difficult studies to perform, because, in humans, they all must be retrospective and all are confounded by alternative or additional environmental exposures. Nevertheless, the following fac to rs have been linked to pregnancy loss: exposure to medications. The latter two exposures have been demonstrated to have both endocrine and immune effects that could lead to poor placentation and subsequent pregnancy loss (300,301). Associations between spontaneous pregnancy loss and exposures to video display terminals, microwave ovens, high-energy electric power lines, and high altitudes. There is no compelling evidence that moderate exercise during pregnancy is associated with spontaneous abortion. In the absence of cervical ana to mic abnormalities or incompetent cervix, coitus does not appear to increase the risk for spontaneous pregnancy loss (304,305). Exposure to three particular substances—alcohol, cigarettes, and caffeine—deserves specific attention. Although some conflicting data exist, one very large epidemiologic study has shown that alcohol consumption during the first trimester of pregnancy, at levels as low as three drinks per week, is associated with an increased incidence of spontaneous pregnancy loss (306–308). Cigarette smoking has also been linked to early spontaneous pregnancy loss; however, this is also not without controversy (309–311). Alcohol and to bacco intake in the male partner correlates with the incidence of domestic violence, which in turn is associated with early pregnancy loss (312). Finally, recent evidence adds to a growing body of literature that suggests consumption of coffee and other caffeinated beverages during early pregnancy is linked to adverse pregnancy outcome (309,313). The most publicized recent report casts doubt on the definition of a lower limit for safe use of caffeine in the first trimester of pregnancy (309). Obesity, stress at work, and use of nonsteroidal anti-inflamma to ry agents during early pregnancy have all been linked to an increased rate of isolated spontaneous pregnancy loss (314–317). Preconception Evaluation Investigative measures that are potentially useful in the evaluation of recurrent spontaneous abortion include obtaining a thorough his to ry from both partners, performing a physical assessment of the woman (with attention to the pelvic examination), and a limited amount of labora to ry testing (Table 33. His to ry A description of all prior pregnancies and their sequence as well as whether his to logic assessment and karyotype determinations were performed on previously aborted tissues are important aspects of the his to ry. Approximately 60% of abortuses lost before 8 weeks of gestation were reported to be chromosomally abnormal; most of these pregnancies are affected by some type of trisomy, particularly trisomy 16 (318,319). The most common single chromosomal abnormality is monosomy X (45X), especially among anembryonic conceptuses (320). Aneuploid losses are particularly prevalent among women with recurrent pregnancy loss who are over the age of 35 (8). Although somewhat controversial, the detection of aneuploidy in miscarriage specimens may be less when the couple experiencing recurrent abortions is euploidic. Alternatively, some investiga to rs have suggested that, because aneuploidy is common among miscarriage specimens from patients experiencing both isolated and recurrent spontaneous pregnancy losses, if aneuploidy is documented in fetal tissues from a recurrent pregnancy loss patient, this loss does not affect their prognosis for future pregnancy maintenance (13). Most women with recurrent pregnancy losses tend to experience spontaneous abortion at approximately the same gestational age in sequential pregnancies (321). Unfortunately, the gestational age when pregnancy loss occurs, as determined by last menstrual period, may not be informative, because there is often a 2 to 3-week delay between fetal demise and signs of pregnancy expulsion (322). The designation of couples experiencing recurrent abortion in to either primary or secondary categories is not helpful in either the diagnosis or management of most women with recurrent abortion. Approximately 10% to 15% of couples cannot be classified in to either the primary or secondary category because, although their first pregnancy resulted in a loss, it was followed by a term delivery prior to subsequent losses. This is defined as the inability to conceive after 12 months of unprotected intercourse. By definition, 15% of all couples will meet this criteria; this number increases to 33% among couples with recurrent pregnancy losses. Because many pregnancies are lost before or near the time of missed menses, subfertility among recurrent pregnancy loss patients may in some cases reflect recurrent preclinical losses. Menstrual cycle his to ry may provide information about the possibility of oligo-ovulation or other relevant endocrine abnormalities in recurrent pregnancy loss patients. An assessment of the timing of intercourse relative to ovulation should be reviewed with couples in an effort to detect dyssynchronous fertilization that could contribute to pregnancy loss (323). A personal and family his to ry of thrombotic events or renal abnormalities may provide vital information. A family his to ry of pregnancy losses and obstetric complications should be addressed specifically. Detailed information about drug and environmental exposure should also be obtained. Estrogenization of mucosal tissues, cervical and vaginal ana to my, and the size and shape of the uterus should also be determined. At present, results are either to o preliminary to warrant unfettered recommendation or studies of their use have been to o contradic to ry to allow final determination of their value. Tests with unproven or unknown utility include: Evaluation of ovarian reserve using day 3 serum follicle–stimulating hormone or antimullerian hormone levels. It appears that decreased ovarian reserve may portend a poor outcome in all patients, including those with recurrent pregnancy loss (110,111). Thrombophilia testing: Fac to r V Leiden, G20210A prothrombin gene mutation, protein S activity Serum homocysteine levels If there is a family or personal his to ry of venous thromboembolic events, obtain protein C activity and antithrombin activity. Fac to r V Leiden and prothrombin promoter mutations are rare in African and Asian populations. Among Asian populations, protein C and protein S are the most common inherited thrombophilias. Testing for antithyroid antibodies among women with recurrent pregnancy loss remains controversial, but is rapidly gaining support (98–100,103,271–273). Investiga to rs have recently demonstrated an increased prevalence of these antibodies among women with a his to ry of recurrent pregnancy loss, even in the absence of thyroid endocrinologic abnormalities (99,100,102,272). Testing for the presence of a variety of au to antibodies (other than lupus anticoagulant and anticardiolipin antibody) has been hotly debated, but without consensus (245,246,249,262,328,329). Testing for some antiphospholipid antibodies, such as antiphosphatidylserine and anti-fi2 glycoprotein-1, are particularly attractive because mechanistic connections between their presence and placental pathology were reported (246,260,261,263,264). Measurement of anti-fi2 glycoprotein-1 antibodies was formally added to the criteria defining the antiphospholipid syndrome, and data are accumulating for specific relevance to pregnancy loss (245,246,251,330). Among patients with known au to immune diseases and recurrent pregnancy loss additional antiphospholipid testing may also be warranted (331). Interobserver reproducibility and accuracy are to o low to reliably use the Noyes criteria to diagnose a luteal phase defect on timed endometrial biopsy (332). More specific and predictive methodology for diagnosing this disorder is not yet available. The following investigations have no place in modern clinical care of patients with recurrent spontaneous pregnancy loss: Evaluations that involve extensive testing for serum or site-specific au to or alloantibodies (including antinuclear antibodies and antipaternal cy to to xic antibodies) are both expensive and unproven. Their use often verifies the statistical tenet that if the number of tests performed reaches a critical limit, the results of at least one will be positive in every patient. Use of other immunologic tests is unnecessary also unless these studies are performed, with informed consent, under a specific study pro to col in which the costs of these experimental tests are not borne by the couple or their third-party payers. Further work is necessary before suppressor cell or fac to r determinations, cy to kine, oncogene, and growth fac to r measurements, or embryo to xic fac to r assessment can be clinically justified. Postconception Evaluation Following conception, close moni to ring of patients with his to ries of recurrent pregnancy loss is advised to provide emotional support and to confirm intrauterine pregnancy and its viability. The incidence of ec to pic pregnancy and complete molar gestation is increased in women with a his to ry of recurrent spontaneous pregnancy loss. Although somewhat controversial, some data suggest that the risk of pregnancy complications other than spontaneous abortion are not significantly different between women with and without a his to ry of recurrent losses (102,334–338). Two uncontested exceptions to this observation are those women who have antiphospholipid antibodies and those who have an intrauterine infection. Other hormonal determinations are rarely of benefit because levels are often normal until fetal death or abortion occurs (340). Ultrasonographic assessment may then be performed every 2 weeks until the gestational age at which previous pregnancies were aborted. The prognostic value of serial ultrasonography and a variety of hormonal and biochemical measurements during early pregnancy in women with his to ries of recurrent losses has been reported (341). If a pregnancy has been confirmed, but fetal cardiac activity cannot be documented by approximately 6 to 7 weeks of gestation (by sure menstrual or ultrasonographic dating), intervention is recommended to expedite pregnancy termination and to obtain tissue for karyotype analysis. First trimester screening with maternal chemistries and fetal nuchal lucency measurement or chorionic villus sampling are recommended for obstetrical indications. Maternal serum can also be obtained for assessment at 16 to 18 weeks of gestation. Amniocentesis may be recommended to assess the fetal karyotype after the pregnancy has progressed past the time of prior losses. The importance of obtaining karyotypic analysis from tissues obtained after pregnancy demise in a woman experiencing recurrent losses cannot be overemphasized.
Muscles quick spasms in lower abdomen buy imitrex 50mg with amex, vertebral joints infantile spasms 2 month old generic imitrex 25mg visa, and discs (including lumbosacral junction spasms of the larynx cheapest generic imitrex uk, paravertebral sacrospinal muscles spasms nose buy on line imitrex, and sacroiliac joints) are common sources of spondylogenic pain that must be examined carefully (2) muscle relaxant reversal agents buy 25 mg imitrex with visa. Diagnosis Diagnostic imaging studies performed while the patient is standing, lying, and sitting with maximal flexion can be helpful. Though most patients with acute back pain do not require imaging, plain films can be obtained to evaluate for infection, fracture, malignancy, spondylolisthesis, degenerative changes, disc space narrowing, and prior surgery. Management Consultation with the patient’s primary care provider should be sought before initiating management for back pain unless the source could be referred gynecologic pain. Psychological Fac to rs From a psychological perspective, various fac to rs may promote the chronicity of pain, including the meaning attached to the pain, anxiety, the ability to redirect attention, personality, mood state, past experience, and reinforcement contingencies that may amplify or attenuate pain (132). Treatment that results in subjective improvement in pain severity and increased activity level produces a significant improvement in personality profile (133). Both give rise to similar behavior, such as behavioral and social withdrawal and decreased activity, and may be mediated by the same neurotransmitters, including norepinephrine, sero to nin, and endorphins. The Beck Depression Inven to ry can be used as a to ol for evaluation; a score over 12 suggests dysphoria and over 18, depression (133a). Childhood physical abuse has been noted to be more prevalent in women with chronic pelvic pain than in those with other types of pain (39% vs. In a comparison of women with chronic pelvic pain, women with nonpelvic chronic pain (headache), and pain-free women, a higher lifetime prevalence of major sexual abuse and physical abuse was found in the chronic pelvic pain group. Childhood traumas may lead to an increased vulnerability to psychosocial stress and impaired coping strategies and promote chronicity of pain after an injury. If patients are taught self-efficacy and adaptive pain coping skills through psychological treatment interventions, pain can be reduced and functioning improved. Dramatizing the pain is a coping mechanism that is used by pain sufferers to generate support from others around them (135). This practice, combined with pain-related anxiety and fear, propagates pain (133). Management of Chronic Pelvic Pain Multidisciplinary Approach the approach to women with chronic pain must be therapeutic, optimistic, supportive, and sympathetic. The patient should be instructed to complete a daily pain ratings form after her first office visit. This form provides the clinician and patient with important information for pain management. Pain level (0–10), vaginal bleeding, and events that trigger pain such as stress, foods, and certain physical activities are recorded. The pain ratings can encourage the patient’s sense of control and decrease feelings of helplessness. Daily recording improves self-efficacy and compliance, allows for diagnosis of atypical cyclic pain (luteal as opposed to menstrual), and helps the patient to recognize the connection between pain and stressors. Offering regular follow-up appointments is preferable to asking the patient to return only if pain persists because the latter reinforces pain behavior. Specific pain management skills should be taught using cognitive-behavioral approaches by a psychologist or using such techniques as mindfulness-based meditation or yoga. Psychotherapy is indicated for women who have pronounced depression, sexual difficulties, or indications of past trauma. Psychological group treatment is a very cost-effective approach for helping patients learn stress reduction techniques and develop coping behavioral mechanisms (136). This approach incorporates the skills of the gynecologist, psychologist, and physical therapist, and may include an anesthesiologist for specialized nerve blocks. Retrospective, uncontrolled studies revealed relief of pain in 85% of the participants (137). One prospective randomized study revealed a similar response rate, which was significantly better than that of traditional therapy for pain and associated symp to m reduction, improvement of daily functioning, and quality of life (138). The following groups of patients should be considered for multidisciplinary therapy early in the management process: (i) no obvious pathology, (ii) pathology that has an equivocal role in pain production, (iii) poor response to traditionally effective medical or surgical management, (iv) more than one visceral or somatic structure involved in the production of pain. Pharmacologic interventions Any patients with dysmenorrhea or pain that worsens in the luteal or menstrual phase should be given hormonal agents to suppress ovulation and/or menses, as discussed above. Patients with neuropathic pain or those with evidence of central sensitization or myofascial pain benefit from agents that alter neural processing. A low dose of a tricyclic antidepressant, various anticonvulsants, or selective sero to nin/norepinephrine reuptake inhibi to rs are often effective, especially if combined with cognitive behavioral therapy. These pharmacologic agents lower the threshold for nerve firing and can help reduce reliance on narcotic pain medication, increasing activity and relieving the impact the pain has on the women’s overall lifestyle (11). Only one small, randomized controlled trial looked at the effect of selective sero to nin reuptake inhibi to rs on pelvic pain, and failed to show a significant difference in pain or functional ability in a short follow-up period (138). Anticonvulsants such as gabapentin or pregabalin are useful for treatment of chronic pelvic pain. Gabapentin plus amitriptyline was more efficacious than amitriptyline alone (139). Ilioinguinal iliohypogastric, pudendal, nerve blocks and trigger point injections can be easily learned by the gynecologist and used liberally where appropriate to down-regulate neural signaling (11). Women with depression should be treated with an appropriate therapeutic dose of antidepressant medication. The role of opioid therapy in chronic pain is controversial and randomized controlled trials are lacking. Long-term management of chronic pelvic pain with narcotic medications is considered a last resort after failure of all other treatment modalities. Opioids should be given on a scheduled basis, and patients should have consistent follow-up with evaluation of the extent of pain relief, level of function, and quality of life. Physicians should carefully document failure of other treatment options and patient counseling. The patient should sign a written contract agreeing to obtain pain medications from only one provider and describing other expectations with respect to treatment. Some other points that the patient should agree to include no early refills or increasing dosage of medication without discussion with the doc to r, no alcohol or illegal drugs, random blood or urine drug screens if needed, and psychiatric or psychological evaluation if needed (140). Diagnostic laparoscopy is a standard procedure in the evaluation of patients with chronic noncyclic pelvic pain; however, laparoscopy is generally withheld until other nongynecologic somatic or visceral causes of pain are excluded. Nonrandomized retrospective and prospective studies suggest that diagnostic laparoscopy provides a positive psychological effect on the treatment of chronic pelvic pain, but this should not be the main goal of laparoscopy (142). During diagnostic laparoscopy, endometriotic lesions should be excised for biopsy, and if infection is suspected, cultures should be performed. The laparoscopy is essentially a debulking procedure, and all visible endometriosis may not be able to be removed safely; but if possible the implants should be excised or electrocoagulated. A Cochrane database review revealed that there is insufficient evidence to recommend pelvic nerve disruption for the treatment of dysmenorrhea (45). The role of pelvic adhesions in pain is unclear, and the efficacy of lysis of adhesions is even more in doubt. Adhesiolysis, even via laparoscopy, is frequently complicated by adhesion reformation and may not be effective for relief of pain in controlled trials (90,144). Other causes must be treated first, and psychological consultation and management should precede or accompany the lysis of adhesions. Hysterec to my Although 19% of hysterec to mies are performed to cure pelvic pain, 30% of patients presenting to pain clinics have already undergone hysterec to my without experiencing pain relief. A multidisciplinary approach including a gynecologist, physical therapist, and a psychologist decreased the frequency of hysterec to my in one study from 16. Hysterec to my is particularly useful for women who have completed childbearing and have secondary dysmenorrhea or chronic pain related to endometriosis, to uterine pathology, such as adenomyosis, or to pelvic congestion. Hysterec to my for central pelvic pain in women with dysmenorrhea, dyspareunia, and uterine tenderness provided relief of pain in 77% of women in one retrospective study and in 74% of women in one prospective cohort study (147,148). Nevertheless, 25% of women in the retrospective study noted that pain persisted or worsened at 1-year follow-up (147). The Maine Women’s Health Study, a prospective cohort study, studied outcomes of 199 women with frequent pain at baseline who underwent hysterec to my. The American College of Obstetricians and Gynecologists outlined criteria that should be met before performing a hysterec to my for pelvic pain (150). They require at least 6 months of pelvic pain without any otherwise correctable pathology. When deciding on the surgical approach, consideration should be given to a vaginal or laparoscopic hysterec to my over an abdominal approach if there are no extensive adhesions expected or large uterine/fibroid size does not preclude it. There are many studies that confirm less morbidity and shorter hospital stays with vaginal compared with abdominal hysterec to mies (151). A prospective study of abdominal versus vaginal versus laparoscopically assisted surgery did not find any statistical difference or worsening of outcomes of urinary or sexual function between the different approaches at 6 months (151).

Metabolic Effects and Safety Venous Thrombosis Women who use estrogen containing hormonal contraceptives are at increased risk for venous thrombosis and thromboembolism. Normally the coagulation system maintains a dynamic balance of procoagulant and anticoagulant systems. For most women, fibrinolysis (anticoagulation) is increased as much as coagulation, maintaining the dynamic balance at increased levels of production and destruction of fibrinogen (127,128) (Fig. Older studies included women with what are now considered contraindications to use of estrogen-containing hormonal contraceptives: previous thrombosis, preexisting vascular disease, coronary artery disease, cancers, and serious trauma (127,128). This is a higher absolute risk than the 3 per 10,000 woman-years previously estimated and may reflect, among other things, the use of better means for diagnosis of deep vein thrombosis (131). This population-based study includes all Danish women aged 15 to 49, excluding only women with a diagnosis of cancer or of cardiovascular disease diagnosed before the study interval. Thrombosis risk was highest during the first year of use and decreased thereafter (Table 10. A much more common variation, fac to r V Leiden exists in 3% to 5% of the Caucasian population. It codes for a one amino acid mutation in the fac to r V protein, inhibiting cleavage of the protein by activated protein C, which is an essential step in maintaining the balance between coagulation and fibrinolysis (109,132). The Leiden allele is found in 3% to 5% of whites but is rare in Africans, Asians, Amerindians, Eskimos, and Polynesians (134). A similar mutation is found in the prothrombin gene at position 20210 and is described as prothrombin G20210A. Pregnancy is an even greater challenge for women with inherited defects of anticoagulation (136). It should not be assumed that hormonal contraception was the unique cause of the thrombotic episode. Routine screening for all women before prescribing hormonal contraception is not justified because effective contraception would be denied to 5% of Caucasian women, and only a small number of fatal pulmonary emboli would be prevented (137,138). Screening women with a personal or family his to ry of deep vein thrombosis before starting estrogen containing hormonal contraception or pregnancy is strongly recommended. Women already diagnosed as having fac to r V Leiden should not receive estrogen-containing contraceptives, i. It is likely that the biases “attrition of susceptibles,” “adverse selection,” and “healthy user bias” explain the apparent increase in thrombosis. Physicians may presume that newer drugs are safer and prescribe them selectively for women with risk fac to rs. In contrast, both Lidegaard’s group in Sweden and van Hylckama Vlieg’s group in the Netherlands reported increased risk with the newer progestins (130,140). It is known that the principal determinants of risk are advancing age and cigarette smoking (141). A to tal of 187 women aged 15 to 44 years with confirmed myocardial infarction were identified during 3. In a later study, the same investiga to rs pooled results from the California study with a similar study from Washing to n State. Most current users were taking low-dose estrogen pills (defined as less than 50 fig of ethinyl estradiol or less than 75 fig of mestranol) with second or third generation progestins, more than half were aged 35 or older, and 26% were current cigarette smokers. The present evidence shows no risk of stroke among women who are otherwise healthy and who use low-dose pills. One study identified all Kaiser Permanente Medical Care Program patients aged 15 to 44 years who sustained fatal or nonfatal stroke in California from 1991 to 1994 (149). Women in developing countries had an apparent modest increase in risk, but this finding was attributed to undetected existing risk fac to rs. Women who smoke and those who have hypertension and diabetes are at increased risk for cardiovascular disease regardless of whether they use oral contraceptives. With the older high-dose pills, as many as 5% of patients could be expected to have blood pressure levels greater than 140/90 mm Hg. The mechanism is believed to be an estrogen-induced increase in renin substrate in susceptible individuals. Low-dose pills have minimal blood pressure effects, but surveillance of blood pressure is advised to detect the occasional idiosyncratic response. Glucose Metabolism Oral estrogen alone has no adverse effect on glucose metabolism, but progestins exhibit insulin antagonism (154). The effect on glucose metabolism, similar to the effect on lipids, is related to androgenic potency of the progestin and to its dose. Lipid Metabolism Androgens and estrogens have competing effects on hepatic lipase, a liver enzyme critical to lipid metabolism. Women whose lipid values are higher than the mean before treatment are more likely to experience abnormalities during treatment (156). Other Metabolic Effects Oral contraceptives can produce changes in a broad variety of proteins synthesized by the liver. The results of actual thyroid function3 tests, as measured by free T and radioiodine tests, are normal (4 158). A similar reduction of risk of ovarian epithelial cancer was found in a prospective study from Norway and Sweden, with borderline tumor risk equally reduced. A 2007 update by these same authors reported a pooled relative risk for all studies of 1. Critics of these studies argued that causation is not proven because few adequately control for the key behavioral fac to rs of partners, use of barrier contraception, and adequacy of cervical cancer screening (168). Adenocarcinomas of the cervix are rare, they are not as easily detected as other lesions by screening cervical cy to logy, and the incidence appears to be increasing. The results of this study were adjusted for his to ry of genital warts, number of sexual partners, and age at first intercourse. Cofac to rs identified with adenocarcinoma included longer-term use of hormonal contraception. To reduce risk, women who are not in mutually monogamous relationships should be advised to use barrier methods in addition to hormonal contraception. A meta-analysis of 54 studies of breast cancer and hormonal contraceptive use reanalyzed data on 53,297 women with breast cancer and 100,239 controls from 25 countries, representing about 90% of the epidemiologic data available worldwide at that time (174). The risk fell rapidly after discontinuation, to 16% 1 to 4 years after s to pping and to 7% 5 to 9 years after s to pping. Results did not differ in any important way by ethnic group, reproductive his to ry, or family his to ry. Since the meta-analysis was published, subsequent studies found no increased risk. Neither family his to ry of breast cancer nor beginning use at a young age was associated with increased risk. A similar study in Sweden compared 3,016 women aged 50 to 74 years who had invasive breast cancer with 3,263 controls of the same age. Liver Tumors Oral contraceptives were implicated as a cause of benign adenomas of the liver. The tumors are rare; about 30 cases per 1 million users per year were predicted with older formulations. This cancer is closely associated with chronic hepatitis B and C infections and is usually seen in cirrhotic livers. A systematic review looked for evidence of harm associated with hormonal contraceptive use among women already at risk because of liver disease (181). Food and Drug Administration approval for premenstrual dysphoric disorder treatment. Health Benefits of Oral Contraceptives Oral contraceptives have important health benefits (Table 10. Contraceptive Benefits Oral contraceptives provide highly effective contraception and prevent unwanted pregnancy, an important public health problem. Where safe abortion services are not available, women seek unsafe services and risk death from septic abortion. Oral contraceptives offer effective therapy for women with menorrhagia and dysfunctional uterine bleeding (163). Sexuality In a study that recorded all episodes of female-initiated sexual behavior throughout the menstrual cycle, an increase in sexual activity at the time of ovulation was noted. Sexual desire decreased over time, but was not affected by the contraceptive method (198). A large study compared women showing signs of threatened abortion who were treated with progestins (primarily ora l medroxyprogesterone acetate) with women who were not treated. The rate of malformation was the same among the 1,146 exposed infants as among the 1,608 unexposed infants (202). Conversely, estrogens taken in high doses in pregnancy can induce vaginal cancer in female offspring exposed in utero. A recent literature search revealed no recent reports linking tera to genicity to hormonal contraception. Perhaps of greatest clinical significance are six antiepileptic d r u g s: pheny to in, phenobarbital, carbamazepine, oxcarbazepine, felbamate, and to piramate (205). Some antiseizure agents have no effect on the levels of contraceptive steroids in the blood. These include valproic acid, vigabatrin, lamotrigine, gabapentin, tiagabine, levetiracetam, zonisamide, ethosuximide, and the benzodiazepines (205). They kill gut bacteria (primarily clostridia) that are responsible for hydrolysis of steroid glucuronides in the intestine, which allows reabsorption of the steroid through the enterohepatic circulation. Oral contraceptive use reduces the metabolic clearance and increases the half-life of those benzodiazepines that are metabolized primarily by oxidation: chlordiazepoxide, alprazolam, diazepam, and nitrazepam. A complete list of interactions is available in the Centers for Disease Control and Prevention’s “U. Patients with persistent break-through spotting or bleeding could be offered a pill with the same low estrogen dose, but a more potent progestin, for example levonorgestrel. The patch is worn for 1 week then replaced with a new patch for 7 days, continuing for 3 consecutive weeks followed by a week with no patch. Pregnancy risk with the patch appears to be higher for women weighing more than 90 kg. The soft, flexible ring is worn in the vagina for 3 weeks, and then removed for 1 week, after which time a new ring is inserted. If inserted on the first day of menstruation, no back up method of contraception is needed.

Determination of whether of any severe illness, operation, injury, or defect is of such a nature or of such recent occurrence as to constitute an undue hazard to the individual or compromise safe performance of duty. Be free from disease of the audi to ry, cardiovascular, respira to ry, geni to urinary, and gastrointestinal systems. Asplenic Soldiers are disqualified from initial training and duty in military specialties involving significant occupational exposure to dogs or cats. Because of certain medical conditions, some Soldiers may require administrative consideration when assignment to combat areas or certain geographical areas is contemplated. Such consideration of their medical conditions would ensure these Soldiers are used within their functional capabilities without undue hazard to their health and well-being as well as ensure they do not produce a hazard to the health or well-being of other Soldiers. In all cases, the role of the commander is to ensure Soldiers do not violate their profiles and are assigned duties that they can perform without undue risk to health and safety. It is the commander’s responsibility to counsel Soldiers with physical profiles that may affect their deployment status. Medical guidance is critical in advising commanders of potential problems, physical limitations and potential situations that could be harmful to the Soldier or detrimental to the mission. Some Soldiers, because of certain medical conditions, may require adminis trative consideration when assigned to combat areas or certain geographic areas. Determination of a Soldier’s assign ment or duties, however, is the commander’s responsibility and is outside of medical recommendations. As such, it is a commander’s responsibility to counsel Soldiers on those duties they may or may not perform while deployed to combat areas or certain geographic areas. The counseled Soldiers will be advised that they will not violate their profiles and will perform duties assigned by the commander which they can perform without undue risk to health and safety. The following medical conditions must be reviewed carefully by the medical provider before making a recommendation as to whether the Soldier can deploy to duty in a combat zone or austere isolated area where medical treatment may not be readily available. If found fit for duty, the Soldier should not deploy to areas where insulin cannot be properly s to red (s to red above freezing level but at less than 86 degrees Fahrenheit) or appropriate medical support cannot be reasonably assured. Deployment should only follow predeployment review and recommendation by an endocrinologist. If after an evaluation by a cardiovascular specialist, the Soldier is found to meet medical retention standards, the Soldier must remain at a location with access to echocardiography and medical moni to ring for 6 months from the date myocarditis was diagnosed. If it is determined that the Soldier can be returned to duty, the Soldier should not deploy if he/she cannot wear protective gear, has experienced recent emergency room visits, or requires repetitive use of oral corticosteroids. Soldiers with any recent musculoskeletal injury or surgery that prevents necessary mobility or firing a weapon should not deploy. If found fit for duty, the Soldier may be deployed unless he/she cannot function in the specific environment in which he/she is being assigned. Soldiers with a psychiatric disorder in remission or whose residual symp to ms do not impair duty performance may be considered for deployment duties. The commander makes the ultimate decision to deploy after consulting with the treating physician or other privileged provider. The availability, accessibility, and practicality of a course of treatment or continuation of treatment in theater or austere environment should be consistent with clinical practice standards. If there are any questions on the safety of psychiatric medication, a psychiatrist must be consulted. The potential for deterioration must be evaluated considering potential environmental demands and individual vulnerabilities. Antipsychotics used to control psychotic, bipolar, and chronic insomnia symp to ms; lithium and anticonvulsants to control bipolar symp to ms; 2. Medications that require special s to rage considerations, for example, refrigeration; 3. Medications that require labora to ry moni to ring or special assessments, including lithium, anticonvulsants, and antipsychotics; 4. Medication prescribed within 3 months prior to deployment that has yet to demonstrate efficacy or be free of significant impairing side effects. Decisions to deploy personnel on such medications should be balanced with necessity for such medication in order to effectively function in a deployed setting, susceptibility to withdrawal symp to ms, ability to secure and procure controlled medications, and potential for medication abuse. If there is any evidence of significant heat in to lerance, the Soldier should not deploy to warm austere climates. Soldiers with a his to ry of cancer who have been returned to duty but have a requirement for periodic moni to ring every 6 months or less should not deploy. Soldiers with recently treated moderate or severe dysplasia may only be deployed to austere environments if coordination is arranged via the unit commander and theater surgeon to ensure follow-up evaluation 7 to 9 months after initial evaluation and treatment. Soldiers with his to ry of malignant hyperthermia should not be assigned to areas where complete anesthesia services are unavailable or to austere environments. Soldiers taking medications should not au to matically be disqualified for any duty assignment. Medications used for serious and/or complex medical conditions are not usually suitable for extended deployments. The medications on the list below are most likely to be used for serious and/or complex medical conditions that could likely result in adverse health consequences. This is not an all-inclusive listing of medications that may render an individual non-deployable but is provided as a guideline to be used during pre-deployment medical screening. Because some medications are used for multiple reasons, any medical screening should take in to account whether the drug is being used for a serious and/or complex medical condition or another use that might be appropriate for a deploying Soldier. A complete medical evaluation should be initiated on those personnel regularly taking the following medications: • Antiarrhythmics. Examples of areas where altitude is an important consideration are La Paz, Bolivia; Qui to, Ecuador; Bogota, Columbia; and Addis Ababa, Ethiopia. Date of medical incapacitation is the date a disqualifying medical condition was definitively diagnosed by his to ry, examination, or test.

All others (that is, new disqualifications or not meeting annual waiver requirements) must be reviewed and co-signed by the supervising flight surgeon for submission. Consultations may be obtained at Government expense when authorized as stated below. The tests and consultations are conducted only to the extent required to determine medical fitness for flying duties and not for the treatment or correction of disqualifying conditions. In no case will the originals be given to the applicant or other individuals not in the procurement chain of command. Waiver and suspension recommendation and approval letters will be filed in the individual health record and flight record. If a disqualifying medical condition is found, a waiver must be granted by the appropriate authority before further flying duties are performed. For all flying classes, each disqualifying defect or condition will be evaluated to determine if it— (1) Is progressive. Treatment means any medical treatment or procedure performed by a non-aeromedical health care provider, and includes, but is not limited to, the following: (1) Any medical or dental procedure requiring use of medications after treatment. The aviation service waiver authority reviews the recommendation of medical fitness for flying duties and makes the final administrative disposition for— (1) Medical termination from aviation service (permanent medical suspension); or (2) Continuation of aviation service with administrative aeromedical waiver. Examples include ankle sprain, acute rhinitis, gastroenteritis, and simple closed fracture. The immediate commander will set the date of medical incapacitation and impose the temporary medical suspension. Continuation of flying duties is only authorized by issuance of orders for an aeromedical waiver (para 6–19) by an aviation service waiver authority.
