An attractive female interviewer approached male passersby either on a fear-arousing suspension bridge or on a non-fear-arousing bridge. The fear-arousing bridge was constructed of boards, attached to cables, and had a tendency to tilt, sway, and wobble. The handrails were low, and there was a 230-foot drop to rocks and shallow rapids below. The interviewer asked subjects to fill out questionnaires that included projective test items. There was more sexual imagery in the questionnaires filled out by the men in the suspension-bridge group, and these men made more attempts to contact the attractive interviewer after the experiment than the men on the control bridge. Intuitively, this result might seem to be peculiar: that men who are in a state of fear are more attracted to a woman than men who are relaxed. But in terms of the Berscheid and Walster two-component theory, it makes perfect sense. The fearful men were physiologically aroused, while the men in the control group were not. And according to this theory, arousal is an important component of love or attraction. Now, of course, if the men (most of them heterosexuals) had been approached by an elderly man or a child, their responses would probably have been different. In fact, when the interviewer in the experiment was male, the effects discussed above did not occur. Society tells us what the appropriate objects of our love, attraction, or liking are. In other words, we know for what kinds of people it is appropriate to have feelings of love or liking. For these men, feelings toward an attractive woman could reasonably be labeled "love" or "attraction. The physical arousal that is important for love need not always be produced by unpleasant or frightening situations. Pleasant stimuli, such as sexual arousal or praise from the other person, may produce arousal and feelings of love. Sexual arousal is one method of producing a state of physiological arousal, and it is one that our culture has taught us to label as "love. On the other hand, this phenomenon may lead us to confuse love with lust, an all-too-common error. Cross-Cultural Research In the past three decades, researchers have studied people from various ethnic or cultural groups to see whether attraction, intimacy, and love are experienced in the same way outside the United States. Three topics that have been studied are the impact of culture on how people view love, on whom people fall in love with, and on the importance of love in decisions to marry. Cultural Values and the Meaning of Love Cross-cultural psychologists have identified two dimensions on which cultures vary (Hatfield & Rapson, 1993a). Individualistic cultures, like those of the United States, Canada, and the western European countries, tend to emphasize individual goals over group and societal goals and interests. Collectivist cultures, like those of China, Africa, and the southeast Asian countries, emphasize group and collective goals over personal ones. Several specific traits have been identified that differentiate these two types of societies (Triandis et al. In individualistic cultures, behavior is regulated by individual attitudes and cost-benefit considerations, and emotional detachment from the group is accepted. In collectivist cultures, the self is defined by its group membership, behavior is regulated by group norms, and attachment to and harmony within the group are valued. Individuals select mates on the basis of such characteristics as physical attractiveness, similarity (compatibility), and wealth or resources. In Chinese society, by contrast, marriages are arranged, and the primary criterion is that the two families be of similar status. Many Western cultures view each person as independent, and value individuality and uniqueness.

Traditional images include the Jezebel, who is promiscuous and immoral; and the Mammy, who is fat and asexual (Stephens & Few, 2007). Contemporary hip-hop culture has added numerous stereotyped images: the Gold Digger, who uses sex to gain economic rewards from men; Gangster Bitches, who live in poverty-stricken, violent environments, focus on survival, and use sex to feel good for the moment; and the Sister Savior, who is strongly tied to African American religious traditions, is virtuous, and avoids sex (Stephens & Few, 2007). Some experts argue that Black men experience even more discrimination than Black women do, according to several indicators including education and criminal justice (Pieterse & Carter, 2007). Stereotypes about Black men tend to be negative, including a belief that all Black men are dangerous. These stereotypes and the discrimination that results from them can be a source of severe stress for Black men. The high unemployment rate for Black men creates a gender-role problem because the role of breadwinner or good provider is such an important part of the male role in the United States. In turn, many Black men are less willing to commit to marriage or other long-term romantic relationships, which affects the structure of the Black family. When we speak of the cultural heritage of Latinos, we must first understand the concept of acculturation, which is the process of incorporating the beliefs and customs of a new culture. The culture of Mexican Americans (Americans of Mexican heritage) is different from both the culture of Mexico and Acculturation: the process of incorthe dominant Anglo culture porating the beliefs and customs of a of the United States. American culture is based on Figure 1 Fathers and sons at the Millions More Movement March in Washington, d. Leaders of the march wanted to encourage African American men to take more responsibility for their families and community, and some 1 million men seemed to agree. Traditional Latinos place a high value on family loyalty and on warm, mutually supportive relationships, so that family and community are highly valued. As noted in the chapter "Sexuality in Perspective," in traditional Latin American cultures, gender roles are sharply defined (Raffaelli & Ontai, 2004). Such roles are emphasized early in the socialization process for children (Raffaelli & Ontai, 2004). Boys are given greater freedom, are encouraged in sexual exploits, and are not expected to share in household work. One woman described how she and her brother, who was one year older than she, were treated by their mother: He had a very much later curfew than I did. He got a car, got to drive a car and then he also got his own car and I never did. I could only go to school-related activities and he could do about anything, he could go any place he wanted. Racist sentiment against the Chinese grew, however, and there was a shift to recruiting first Japanese and Koreans and then Filipinos. Then, in the late 1960s and the 1970s, there was a mass exodus to the United States of refugees from war-torn Southeast Asia. The cultural values of Asian Americans are in some ways consistent with white middle-class American values but in other ways contradict them. Asian Americans share with the white middle class an emphasis on achievement and on the importance of education. For example, Asian American women have a higher level of education, on average, than white American women (U. On the other hand, Asian Americans place far more value on family and group interdependence (Kim et al. One has an obligation to the family, and the needs of the family must take precedence over the needs of the individual. For Asian American women, there can be a conflict in cultural values, between the traditional gender roles of Asian culture and those of modern Anglo culture, which increasingly prizes independence and assertiveness in women. Just as the sexuality of African Americans has been stereotyped, so too has that of Asian Americans. The Asian American man has been stereotyped as asexual (lacking in sexuality), whereas the Asian American woman has been stereotyped as an exotic sex toy (Reid & Bing, 2000). Compared with European Americans, Asian Americans tend to hold more conservative sexual attitudes and to experience more anxiety about sex (Brotto et al. The more acculturated that Asian American women are, the closer their sexual attitudes are to those of European American women (Brotto et al.

There was a higher incidence of embryonic and fetal resorptions in animals treated with 300 times the short-term RfD. Secondary observations in an animal study included sedation, ataxia and tremors at a dose more than 1500 times the subchronic RfD. Yes1 Yes2 Yes3 Yes4 Yes5 Note: Even if testing for a specific health effect was not conducted for this chemical, information about that effect might be available from studies conducted for other purposes. Estrogen, testosterone and thyroid hormone levels and hormone receptor results from laboratory animal studies at doses below 5 mg/kg-d have been inconsistent and contradictory. However, study design limitations, dose-response interpretation issues, inconsistencies in results and conflicting data in the low dose region exists. In a rodent study assessing effects resulting from early life (in utero and direct dosing for 3 months after birth) changes in estradiol, thyroid hormone, progesterone and prolactin levels were reported only at doses more than 3,000-fold higher than the RfDs presented above. Effects on serum levels of sex hormone ratios are considered as co-critical effects for the short-term duration. Several studies found no effect on adult spleen or thymus weights or histopathology of adult immune organs but one study reported spleen and thymus atrophy at a dose 4,500 times higher than the short-term RfD. In general, doses more than 90 times higher than the short-term RfD and more than 2,000 times higher than the subchronic/chronic RfDs are required to elicit a significant immune response. Inconsistent results have been reported for IgG2a, interferon-, and splenic cell numbers. These low dose cellular-level effects have not been associated with adverse functional immune outcomes related to enhancement or suppression of response to pathogens and the biological significance is uncertain. Database limitations and uncertainties regarding available immune system data were considered in the derivation of the RfDs. The spleen, an immune system organ, was 2 Minnesota Department of Health Rules on the Health Risk Limits for Groundwater July 2015 120 identified as a co-critical developmental additivity endpoint based on transient organ weight effects in weanling animals. See footnote #5 below for information about neurodevelopmental effects for brain and behavior. A statistically significant increase in mammary gland ductal hyperplasia, a potential indicator of mammary gland development, was reported in rats at a dose over 30,000 times higher than the chronic RfD. The biological significance of this finding will not be known until results from an ongoing chronic study become available. Delayed puberty in male and female animals has been reported, although a recent large-scale study in rats found no effects on pubertal onset, except for delayed testes descent reported at a dose over 1,000 times higher than the shortterm RfD. Developmental effects are considered as critical and co-critical effects for the short-term duration RfD and uncertainties related to neurobehavioral effects and metabolic disease are addressed in the derivation of the RfDs using a database uncertainty factor. Female reproductive effects, including decreased numbers of litters per breeding pair and changes in hormone ratios, are considered co-critical effects in the derivation of the short-term RfD. Estrous cycle effects were reported at doses 450 times higher than the short-term RfD and over 11,000 times higher than the subchronic/chronic RfDs. Male reproductive effects were reported in adult animals and included multinucleated giant cells in seminiferous tubules, reduced spermatogenesis in pubertal animals and various reproductive organ weight effects (testes, prostate, seminal vesicles, and epididymis). Male and female reproductive effects are considered as co-critical effects for the derivation of the short-term RfD. This means that there are insufficient data from human studies, but limited evidence of potential neurotoxicity in some animal studies cannot be dismissed, although significance to humans is unknown. Experimental evidence in a well-conducted developmental neurotoxicity study in rats does not support brain developmental neuropathological changes in offspring exposed via maternal dietary doses up to 700 times higher than the short-term RfD. Low dose (defined as doses < 5 mg/kg-d) gestational and/or neonatal exposures have been reported to cause various neurodevelopmental effects in offspring in a variety of studies. Some studies suggest possible effects of early life exposure on various sexually dimorphic behaviors, changes in maternal behaviors nursing and nesting behaviors, anxiety, aggression and learning performance resulting from doses below the short-term RfD; however, there has been a lack of consistency, reproducibility and a variety of study design or reporting limitations in existing data. Several brain morphology studies with various methodological flaws and/or using routes of exposure that are not relevant for evaluating the oral route. These effects occurred at high gavage doses that were over 700 times higher than the short-term RfD.

The protective effect of interleukin-37 on vascular calcification and atherosclerosis in apolipoprotein Edeficient mice with diabetes. The re-entrant circuit involves conduction anterograde over a slow atrioventricular node pathway followed by retrograde conduction over a fast atrioventricular node pathway. Mild: patient overall not worried about diagnosis; has very infrequent events; has not experienced syncope or presyncope. Moderate: patient experiences some anxiety due to symptoms and perceived symptoms; may have experienced presyncope; minimal limitations to lifestyle. Severe: patient is very anxious, with or without recurrent symptoms; has experienced syncope; significant limitations in lifestyle or high risk profession. Patient preference and comfort level with taking drugs versus invasive procedures. Patient ability and interest to self-manage with conservative approach, such as vagal maneuvers and "pill-in-the-pocket" drug therapy. Cost considerations, including upfront cost for invasive procedures versus long term costs of medical therapy. Three items were assessed: artifacts (horizontal A lines or vertical B lines indicating interstitial syndrome), lung sliding, and alveolar consolidation and/or pleural effusion. Combined with venous analysis, these items were grouped to assess ultrasound profiles. Multiple anterior diffuse B lines with lung sliding indicated pulmonary edema (n 64) with 97% sensitivity and 95% specificity. A normal anterior profile plus deep venous thrombosis indicated pulmonary embolism (n 21) with 81% sensitivity and 99% specificity. Anterior absent lung sliding plus A lines plus lung point indicated pneumothorax (n 9) with 81% sensitivity and 100% specificity. Anterior alveolar consolidations, anterior diffuse B lines with abolished lung sliding, anterior asymmetric interstitial patterns, posterior consolidations or effusions without anterior diffuse B lines indicated pneumonia (n 83) with 89% sensitivity and 94% specificity. Conclusions: Lung ultrasound can help the clinician make a rapid diagnosis in patients with acute respiratory failure, thus meeting the priority objective of saving time.

Their efforts to enforce their religious convictions by legislation have created one of the most intense churchstate controversies of the late 20th and early 21st centuries (see the chapter "Sex and the Law"). Their position is odious to pluralists and to those who have benefited by the liberalization of laws and attitudes concerning sexuality. These persons fight to keep what they consider to be gains, while pro-family and New Right activists seek to turn the clock back to what they perceive to have been a healthier and more moral time. Liberal Jewish, Catholic, and Protestant groups, which have tended to accommodate at least some of the New Morality, have been under attack from portions of their own membership on such issues as abortion and homosexuality. Sex Outside Marriage the religious tradition underlying Western ethics has almost always seen sexual intercourse as legitimate only in marriage. Thus, the tradition has condemned both sex before marriage (fornication) and sex by persons married to others (adultery). Today, this position continues to be held by theological conservatives among Jews, Protestants, and Roman Catholics. This option is contrary to Christian doctrine, which states that every genital act must be within the framework of marriage. Among these are the development of safe and reliable contraception, later age at first marriage, the fact that many people suffer the loneliness of divorce and 6 Official statements about sexual topics from Jewish and Christian denominations have been compiled by the Religious Institute, These ethicists are concerned that people be given more helpful guidance than "thou shalt not" and "just say no. Criteria for judging the morality of nonmarital sexual acts could include the following (Countryman, 1994). Finally, many ethicists would insist that moral sexual behavior must include genuine openness and honesty between the partners. Public and private institutions, in this view, should be involved in helping people to make good ethical choices about sexual behavior in a culture that tends to glorify and exploit sex (Lebacqz, 1987; Moore, 1987). In the Hebrew Bible, the penalty for it was to be stoned to death; in the New Testament, it is the only grounds for divorce allowed by Jesus (Matthew 6:2122). With increased psychological awareness, adultery has been understood as a serious breach of trust by a spouse, as well as an act of unfaithfulness to God (a violation of religiously significant promises). Few contemporary ethicists seek to modify this position, but many would argue for a less judgmental, more humane approach to those involved. In this view, people in extramarital relationships should be helped to find the root causes of their infidelity and to move toward a reconciliation with their spouses based on forgiveness and love. Above all, some argue, religious organizations need to assist people in establishing and maintaining good marriages based on mutual respect, communication, and commitment. Those who oppose birth control for religious reasons see it as being contrary to the will of God, against the natural law, or both. Orthodox Judaism cites the biblical command to "be fruitful and multiply" (Genesis 1:26), not to be disobeyed in any way. Furthermore, some members of other Jewish communities warn that limiting family size threatens the future existence of the Jewish people, and they call for a return to the traditionally large Jewish family. In the task of transmitting life, therefore, they are not free to proceed completely at will, as if they could determine in a wholly Why is the Roman autonomous way the Catholic Church opposed honest path to fol- to contraception? Moreover, most ethicists would suggest that unmarried persons who are sexually active ought to be using birth control. Those in the religious community who favor the use of contraceptives do so for a variety of reasons. Many express a concern that all children who are born should be "wanted," and they see family planning as a means to this end. Others, emphasizing the dangers that overpopulation poses to the quality and future of human life, the need for a more equitable distribution and conservation of natural resources, and the needs of the emerging nations, call for family planning as a matter of justice. Another point of view regards the use of contraceptives as part of the responsible use of freedom. In this view, any couple who are unwilling or unready to assume the responsibility of children have a duty to use contraceptives. For these groups, the decision to use contraceptives is a highly individual one, and the government must allow each individual the free exercise of his or her conscience (Curran, 1988).

A 57-year-old man comes to the cardiovascular rehabilitation clinic to begin an exercise program. The patient suffered a myocardial infarction 3 months earlier and had a drug-eluting stent inserted into a branch of the left anterior descending coronary artery. Imaging indicates a recovery of myocardial blood flow, and the patient is counseled to begin an exercise program to strengthen his heart. Heart rate is monitored through an electrocardiogram, arterial oxygen saturation is monitored through a pulse oximeter, and blood pressure is taken at regular intervals. At low exercise intensity, arterial pressure increases to 140/85 mm Hg, heart rate increases to 120 beats/ min, and respiratory rate increases to 30/min. After 10 minutes, an increase in exercise intensity causes little change in arterial pressure but pulse oximetry fell to 91%. Ten minutes later, intensity level was again increased, and the exercise was stopped after 2 additional minutes. Respiratory rate was 30/min and pulse oximetry was 89% when the patient was stopped from exercising. The patient was monitored for an additional 20 minutes during the recovery phase from exercise. Consequently, the increasing ventilation during exercise is not mediated by the peripheral or central chemoreceptors. The majority of the increasing ventilation during exercise is mediated by the higher centers of the central nervous system, including the motor cortex. The increase in alveolar ventilation is not hyperventilation but rather is physiologically appropriate and is matched with the increase in carbon dioxide production by the exercising muscles. Even during strenuous exercise, blood remains in the pulmonary capillaries long enough to come into equilibrium. The patient should be given a diuretic to reduce body fluid volume as a first step in treating the edema. In individuals with impaired diffusion capability, however, the blood in the pulmonary capillaries may not reach equilibrium with alveolar gas. Exercise increases the velocity of blood flow to the pulmonary circulation and, consequently, diminishes time for diffusion to occur. Thus, exercise may exacerbate the diffusion-limited gas exchange characteristic of early stages of pulmonary edema. The impairment of oxygen exchange is more apparent than that of carbon dioxide exchange, because oxygen is much less soluble in water than is carbon dioxide. The impairment in oxygen exchange is reflected by the fall in the pulse oximetry values. Consequently, an individual with either impaired cardiac function and/or impaired pulmonary function will not be able to exercise at a normal workload. When oxygen delivery is inadequate to support metabolic need, the tissues shift to an anaerobic metabolism for a short period of time, which generates an oxygen debt that must be repaid on cessation of exercise. A 17-year-old man is brought to the emergency department by his coworkers because of "abnormal behavior. Cyanide poisons the mitochondria by binding to cytochrome oxidase, uncoupling the oxidative phosphorylation pathway by preventing electron transport. One difference is the arterial blood gases in this case will show elevated Po2 (because the body in not using it for metabolism) and diminished Pco2 (because little is being produced). The mixed venous blood gases show an elevated O2 because tissue extraction of O2 is greatly diminished. The impaired neuronal function results in altered mental status, including confusion, lethargy, dizziness, and headache. Mixed venous blood Po2 is elevated, and Pco2 is low, owing to the lack of aerobic metabolism in the tissues. Arterial blood gas values show slightly elevated Po2, reflecting a slight increase in alveolar Po2 due to the fall in Pco2. The patient has a high respiratory rate from hypoxic stimulation of the arterial chemoreceptors. The arterial Po2 is elevated, but the arterial chemoreceptors have to metabolize oxygen to sense Po2 levels.

A dosage of 5 mg/kg/day is recommended for amphotericin B lipid complex and 35 mg/kg/day for liposomal amphotericin B. In a randomized, double-blind trial in adults, fluconazole and itraconazole were equivalent in treating nonmeningeal coccidioidomycosis. This dosage is required to achieve serum concentrations equivalent to the adult dosage of 400 mg/day (249). Fluconazole and itraconazole appear to be safe in combination with antiretroviral therapy. Skin rash and pruritis might be observed, and rare cases of Stevens-Johnson syndrome have been reported. Asymptomatic increases in transaminases occur in 1%13% of patients receiving azole drugs. Management of Treatment Failure In addition to monitoring the patient for clinical improvement, monitoring coccidioidal IgG antibody titers by the complement fixation methodology is useful in assessing response to therapy. If therapy is succeeding, titers should decrease progressively, and a rise in titers suggests recurrence of clinical disease. However, if serologic tests initially were negative, titers during effective therapy may increase briefly and then decrease (322). This lag in response during the first 1 or 2 months of therapy should not be construed as treatment failure. Infusion-related fevers, chills, nausea, and vomiting also can occur, although they are less frequent in children than in adults. Hepatic toxicity, thrombophlebitis, Clinical information is limited about new therapeutic agents. Posaconazole was effective in six patients with disease refractory to treatment with azoles and amphotericin B (328). Voriconazole was effective in treating coccidioidal meningitis and nonmeningeal disseminated disease in patients who did not respond to fluconazole or were intolerant of amphotericin B (329,330). Caspofungin alone successfully treated disseminated coccidioidomycosis in a renal transplant patient intolerant of fluconazole and in persons in whom conventional therapy failed (331,332). Adjunctive interferon-gamma was successfully used in a critically ill adult with respiratory failure who did not respond to amphotericin B preparations and fluconazole (334). Development of hydrocephalus in coccidioidal meningitis does not necessarily indicate treatment failure. In coccidioidal meningitis, response rates to the azoles can be excellent, but cures are infrequent, and relapse after cessation of therapy is common, occurring in as many as 80% of patients (338). Clinical Manifestations Cryptococcosis often presents with subtle and nonspecific findings such as fever and headache. In contrast to this indolent presentation, children in Zimbabwe presented with an acute form of neurologic cryptococcosis (69% with nuchal rigidity, 38% with seizure activity, and 23% with focal neurologic signs) (344). Disseminated cryptococcosis can be associated with cutaneous lesions, including small, translucent umbilicated papules (indistinguishable from molluscum contagiosum), nodules, ulcers, and infiltrated plaques resembling cellulitis. Diagnosis of pulmonary cryptococcosis without dissemination is unusual among children. Presenting findings include unexplained recurrent fever, cough with scant sputum, intrathoracic lymphadenopathy, and focal or diffuse pulmonary infiltrates. Alternatively the infection may be asymptomatic, with pulmonary nodules revealed on routine chest radiograph (340). Diffuse pulmonary disease can be diagnosed through bronchoalveolar lavage and direct examination of India ink-stained specimens, culture, and antigen detection. Prevention Recommendations Preventing Exposure No strategies have been proven to prevent exposure. Serologic studies of immunocompetent children in an urban setting indicate that most children are infected by C. Discontinuing Primary Prophylaxis immunocompromised hosts with cryptococcosis require treatment because the condition is often fatal in the absence of treatment. Although antifungal treatment is effective, immune reconstitution of the host with the use of antiretroviral medications is crucial to the long-term outcome in terms of avoiding episodes of recurrence and relapse.

Increasing Knowledge · Teach patient about situations that can precipitate a sickle cell crisis and steps to take to prevent or diminish such crises (eg, keep warm, maintain adequate hydration, avoid stressful situations). Monitoring and Managing Potential Complications Management measures for many of the potential complications are delineated in the previous sections; additional measures should be taken to address the following issues. Promoting Home- and Community-Based Care · Involve the patient and his or her family in teaching about the disease, treatment, assessment, and monitoring needed to detect complications. Evaluation Expected Patient Outcomes · Reports control of pain · Is free of infection A 54 Aneurysm, Aortic · Expresses improved sense of control · Increases knowledge about disease process · Experiences absence of complications For more information, see Chapter 33 in Smeltzer, S. Aneurysm, Aortic An aneurysm is a localized sac or dilation formed at a weak point in the wall of the artery. Historically, the cause of abdominal aortic aneurysm, the most common type of degenerative aneurysm, has been attributed to atherosclerotic changes in the aorta. Occasionally, in an aorta diseased by arteriosclerosis, a tear develops in the intima or the media degenerates, resulting in a dissection. Arterial dissections are three times more common in men than in women and occur most commonly in the age group of 50 to 70 years. Thoracic aortic aneurysms occur most frequently in men between the ages of 40 and 70 years. The thoracic area is the most common site for the development of a dissecting aneurysm. Abdominal aortic aneurysms are more common among Caucasians and affect men four times more often than women. Gerontologic Considerations Most abdominal aortic aneurysms occur in patients between 60 and 90 years of age. Rupture is likely with coexisting hypertension and with aneurysms more than 6 cm wide. In most cases at Aneurysm, Aortic 55 A this point, the chances of rupture are greater than the chance of death during surgical repair. If the elderly patient is considered at moderate risk of complications related to surgery or anesthesia, the aneurysm is not repaired until it is at least 5. Clinical Manifestations Thoracic Aortic Aneurysm · Symptoms vary and depend on how rapidly the aneurysm dilates and affects the surrounding intrathoracic structures; some patients are asymptomatic. An alternative for treating an infrarenal abdominal aortic aneurysm is endovascular grafting, which involves the transluminal placement and attachment of a sutureless aortic graft prosthesis across an aneurysm. Nursing Management Preoperative Assessment · Assessment is guided by anticipating a rupture (signs include persistent or intermittent back or abdominal pain that may be localized in the middle or lower abdomen or lower back) and by recognizing that the patient may have cardiovascular, cerebral, pulmonary, and renal impairment from atherosclerosis. Aneurysm, Intracranial 57 A Postoperative Assessment · Frequently monitor pulmonary, cardiovascular, renal, and neurologic status. Hematomas into the scrotum, perineum, flank, or penis indicate retroperitoneal rupture. Aneurysm, Intracranial An intracranial (cerebral) aneurysm is a dilation of the walls of a cerebral artery that develops as a result of weakness in the arterial wall. Its cause is unknown, but it may be due to atherosclerosis, a congenital defect of the vessel walls, hypertensive vascular disease, head trauma, or advancing age. Most commonly affected are the internal carotid, anterior or posterior cerebral, anterior or posterior communicating, and middle cerebral arteries. Symptoms are produced when the aneurysm presses on nearby cranial nerves or brain tissue or ruptures, causing subarachnoid hemorrhage. Prognosis depends on the age and neurologic condition of the patient, associated diseases, and the extent and location of the aneurysm. Clinical Manifestations · Neurologic deficits (similar to those of ischemic stroke) · Rupture of the aneurysm causes sudden, unusually severe headache; often, loss of consciousness for a variable period; pain and rigidity of the back of the neck and spine; and visual disturbances (visual loss, diplopia, ptosis). A 58 Aneurysm, Intracranial · If the aneurysm leaks blood and forms a clot, patient may show little neurologic deficit or may have severe bleeding, resulting in cerebral damage followed rapidly by coma and death. Medical Management · Allow the brain to recover from the initial insult (bleeding). Diagnosis Nursing Diagnoses · Ineffective tissue perfusion (cerebral) related to bleeding or vasospasm · Disturbed sensory perception due to the restrictions of aneurysm precautions · Anxiety due to illness or restrictions of aneurysm precautions Collaborative Problems/Potential Complications · Vasospasm · Seizures · Hydrocephalus · Aneurysm rebleeding · Hyponatremia Planning and Goals Patient goals include improved cerebral tissue perfusion, relief of sensory and perceptual deprivation, relief of anxiety, and absence of complications.

Gender reassignment is comprised of many different procedures over varying timelines subject to many different patient variables. Each patient is unique and the procedures that are done are based on the individual need and emotional status. Procedures to change genitalia are rarely performed without other procedures, which may be extensive. Reassignment can take years and may require maintenance therapy for undefined periods of time. This means the procedures are performed for a variety of diagnosis considerations. Considerations for policy changes; the codes marked definitive gender reassignment procedures, although always performed for gender reassignment, are not age specific. This means that the service could be performed on a baby with ambiguous genitalia. There are no direct crosswalks or relationships between professional codes and facility codes. Some procedures will be inpatient, some will be outpatient and many may be office injections or procedures. These professional codes have prior authorization in place based on medical necessity and allow for procedures to be performed post disease or accident. Important Note * ForwardHealth Hospital Policy does indicate that gender reassignment surgery is non-covered. However, the current reimbursement methadology for facilities does not edit for surgery related to gender reassignment at the code level or at the reimbursement grouper level.

The discussion is intended to convey the limitations of the assessment and to aid and guide the risk assessor in the ensuing steps of the risk assessment process. Comments from all peer reviewers were evaluated carefully and considered by the Agency during the finalization of this assessment. The RfD and RfC provide quantitative information for use in risk assessments for health effects known or assumed to be produced through a nonlinear (possibly threshold) mode of action. The RfD (expressed in units of mg/kg-day) is defined as an estimate (with uncertainty spanning perhaps an order of magnitude) of a daily exposure to the human population (including sensitive subgroups) that is likely to be without an appreciable risk of deleterious effects during a lifetime.
