By causing mesenteric congestion menopause weight gain purchase lady era 100 mg otc, right ventricular failure can impair the rate of absorption of diuretics; by causing renal hypoperfusion menstruation diarrhea order 100 mg lady era free shipping, left ventricular failure can impede the delivery of diuretics to active sites in the renal tubules menopause vitamins buy on line lady era. As a result women's health center dickson tn buy cheap lady era 100mg line, as heart failure advances, patients become increasingly resistant to the effects of diuretic drugs and require larger and larger doses to achieve a therapeutic response. Management of Refractory Peripheral Edema Several strategies should be considered in the management of patients with refractory edema. Non-steroidal anti-inflammatory drugs, which can decrease the efficacy and increase the risk of diuretics, should be withdrawn. If the patient fails to respond to the intravenous administration of large doses of furosemide, the physician may add a second diuretic with a different renal tubular site of action. A combination of two diuretics can produce a dramatic increase in urine output, but such a regimen is commonly accompanied by striking (and occasionally life-threatening) degrees of hypokalemia. If a combination of intravenous furosemide and oral metolazone proves ineffective, these diuretics should be co-administered with drugs that increase renal blood flow. Finally, if the edema becomes refractory to all pharmacologic interventions, hemofiltration or peritoneal dialysis may be useful in restoring fluid balance in selected patients. Regardless of the severity of fluid retention, every effort should be made to achieve dry weight, even if achievement of this goal requires a prolonged hospitalization. Patients discharged prematurely with residual edema due to an inadequate diuresis are commonly readmitted to the hospital for refractory edema within several weeks. In contrast, patients who achieve dry weight frequently become responsive to conventional treatments for heart failure and have a lower risk of recurrent hospitalization. Pulmonary Congestion (Acute Pulmonary Edema) One of the most common clinical presentations of advanced left ventricular failure is the syndrome of pulmonary congestion. These patients complain of dyspnea at rest and have pulmonary rales on physical examination. Pulmonary congestion may be the first evidence of heart failure in patients without a history of cardiac disease; it may appear in patients who are already hospitalized for an acute cardiac disorder. If severe, abrupt, and accompanied by clinical evidence of sympathetic overactivity (tachycardia, diaphoresis and vasoconstriction), the syndrome is designated as acute pulmonary edema. Acute pulmonary edema may also be triggered by non-cardiac disorders, including direct injury to the alveolar-capillary membrane, high-altitude stress, catastrophes of the central nervous system, narcotic overdose, or pulmonary embolism. Regardless of its cause, pulmonary edema reflects the transudation of fluid into the alveolar space and arises from an imbalance in the factors that regulate the transport of fluid from the pulmonary microcirculation to the interstitial space of the lung. When the cause of the syndrome is cardiac, pulmonary edema results from the rapid onset of intense peripheral vasoconstriction that leads to a marked increase in pulmonary venous pressures. The profound constriction of systemic arteries and veins causes a sudden and dramatic redistribution of blood from peripheral reservoirs to the pulmonary circuit, causing the pulmonary capillary hydrostatic pressure in the lung to exceed the capillary colloid osmotic pressure. However, the transudation of fluid into the alveoli cannot occur if pulmonary blood flow is impaired; thus, patients with an elevated pulmonary vascular resistance or depressed right ventricular function rarely develop acute pulmonary edema. Management of Pulmonary Edema Several general measures are advisable for most patients with pulmonary congestion. Every effort should be made to identify an underlying precipitating factor, because its correction is often critical to the success of treatment. Patients usually feel most comfortable resting in bed in the upright position with the legs dependent. Special attention should be devoted to maintaining adequate oxygenation, which can be achieved by increasing the concentration of 225 inspired oxygen or (if necessary) by endotracheal intubation and mechanical ventilation. Given the importance of peripheral vasoconstriction in the pathogenesis of pulmonary edema, pharmacologic dilation of peripheral vessels represents the critical element in any successful approach to management. This goal can be achieved with the use of (1) morphine; (2) loop diuretic drugs. Because of the need for rapid and reliable treatment, these interventions are generally administered intravenously. Morphine remains the most effective single agent for the treatment of acute cardiogenic pulmonary edema. The drug acts specifically to antagonize the peripheral vasoconstrictor effects of the sympathetic nervous system; the resultant vasodilatation leads to an immediate and dramatic decline in pulmonary arterial and venous pressures, leading directly to symptomatic improvement. The magnitude of venodilation produced by the drug in the limbs is insufficient to explain its effects on pulmonary flow and pressures; instead, morphine appears to act primarily to increase the pooling of blood in the splanchnic circulation. In addition, morphine blunts the chemoreceptor-mediated ventilatory reflexes that trigger the severe tachypnea that accompanies pulmonary edema; by doing so, the drug reduces the work of breathing and thereby oxygen demand.

The lack of physical findings does not exclude the presence of mild to moderate volume contraction in a given patient menstrual kit buy lady era 100 mg overnight delivery. In the postoperative period pregnancy years after vasectomy purchase lady era without prescription, 7 to 10% blood volume losses in patients are often accompanied by normal vital signs and by only slight decreases in the central venous pressure or the pulmonary capillary wedge pressure women's health center haverhill ma buy lady era 100mg overnight delivery. Skin turgor and the moistness of mucous membranes are valuable indices to the volume of body water in infants but are unreliable in adults menstrual tumblr cheap lady era amex. In young adults, reductions in skin turgor do not occur unless profound volume contraction is present, and normal loss of skin elasticity makes skin turgor difficult to assess in older patients. Similarly, mouth breathing and other factors affect the oral mucosa independently of external volume balances. Consequently, the clinical findings in volume contraction depend primarily on the interplay among four major factors: (1) the magnitude of the volume loss; (2) the rate of volume loss; (3) the nature of the fluid loss, that is, whether the fluid loss is primarily water, a combined sodium plus water loss, or a blood loss; and (4) the responsiveness of the vasculature to volume reduction. The clinical manifestations of volume contraction are obviously related intimately to the volume and rate of fluid loss. For example, an acute gastrointestinal hemorrhage of 1 L of blood can easily result in oliguria, coupled with the signs and symptoms of circulatory collapse, while the hematocrit remains constant. In other words, the hemorrhage is sufficiently acute that fluid flux from the interstitial to the vascular bed makes a negligible contribution to expanding the vascular bed. Second, the kind of fluid loss significantly affects the clinical findings in volume contraction. Consider, for example, a 1-L loss of different kinds of body fluids in a 70-kg man with a total body water of 40 L and a hematocrit of 45%. The acute loss of 1 L of predominantly solute-free water, as in diabetes insipidus, reduces the blood volume by 2. Lastly, the acute loss of 1 L of blood by hemorrhage reduces blood volume by 20%, thus resulting in profound oliguria and near circulatory collapse. Finally, peripheral vasoconstriction and tachycardia represent important physiologic responses to volume losses. Consequently, even modest signs and symptoms of volume contraction are amplified appreciably in patients with diminished myocardial reserve or reduced sympathetic nervous system function. The former occurs commonly in cardiomyopathies of any cause or in pericardial tamponade or pericardial constriction. The latter occurs commonly in patients on prolonged bed rest, in diabetic patients with autonomic neuropathy, and as a consequence of therapy with certain antihypertensive drugs. The pulse, blood pressure, and changes of these variables with position, together with a clinical estimate of the venous pressure and skin temperature, provide an initial assessment of circulatory dynamics. Wide variations exist in blood pressure and pulse changes to orthostatic measurements. A decrease in orthostatic diastolic blood pressure of 10 mm Hg is considered to be the most reliable indicator of significant volume depletion. Even then, a physician cannot be certain, and it is useful to consider a fluid challenge to evaluate patients in whom a volume deficit is thought to contribute to a reduced cardiac output. A convenient way of achieving this goal is to administer 500 mL of normal saline over 1 to 3 hours. In patients with a normal cardiac reserve, the effect of a fluid challenge may be monitored safely by evaluating the pulse, blood pressure, and urine flow. In patients with impaired cardiac function, using a flow-directed Swan-Ganz catheter to measure the pulmonary capillary wedge pressure or cardiac output, as estimated by thermal dilution, provides a more precise indicator to early volume overload secondary to a fluid challenge. Because volume contraction is associated with vasoconstriction, both in the venous and the arterial circuits, transient changes in the pulmonary capillary wedge 544 pressure may not accurately reflect volume status. The initial pressure elevation is due to fluid infusion into a vasoconstricted, low-capacity vascular bed and should not be misinterpreted to indicate adequacy of volume repletion. The subsequent reduction in wedge pressure coincides with decreases in arterial resistance coupled with increases in venous capacitance. Finally, central venous pressure measurements provide unreliable estimates of pulmonary vascular volume. The cardinal laboratory findings associated with volume contraction follow directly from the volume repletion mechanism summarized in Figure 102-2. The kidney initially responds to a decrease in effective circulating blood volume by reducing urine volume and sodium excretion. Severe degrees of volume contraction also reduce filtration rate and result in prerenal azotemia and a decrease in fractional excretion of sodium (see Chapter 100).

In addition to their content of pre-formed granule proteins womens health las vegas cheap lady era online mastercard, eosinophils also elaborate newly synthesized lipid mediators women's health quinoa recipes purchase lady era 100mg amex, including the 5-lipoxygenase pathway-derived eicosanoid leukotriene C2 and platelet activating factor menstruation and fatigue cheap lady era 100 mg line. Like neutrophils breast cancer z11 order lady era pills in toronto, eosinophils can serve as end-stage effector cells, but eosinophils have specialized roles in host defense and act primarily against multicellular parasites that cannot be eradicated by phagocytosis. Although eosinophils are capable of phagocytosing and killing bacteria and other small microbes, eosinophils do not have a major role in vivo in host defense against such microbial pathogens and cannot constitute an effective defense against bacterial infections in situations in which neutrophil function is deficient. Rather, eosinophils function in host defense against large, non-phagocytosable organisms, most notably the multicellular, helminthic parasites. Eosinophils can invoke several mechanisms, including their cytotoxic cationic granule proteins, for antiparasitic host defense. Released eosinophil cationic proteins are toxic to host cells, and the dysfunction and damage elicited by eosinophil granule proteins may contribute to the pathogenesis of diseases in which heightened numbers of eosinophils are found within involved tissues. The effector functions of mature eosinophils, whether they are mediated by release of pre-formed granule proteins or by the synthesis of new lipid mediators, can be stimulated by cytokines, including interleukin-5 and granulocyte-macrophage colony-stimulating factor. Blood eosinophil numbers do not always reflect the extent of eosinophil involvement in affected tissues in various diseases. Eosinophils usually number less than 450/muL in the blood; the count has a mild diurnal variation, being higher in the early morning and falling as endogenous glucocorticosteroid levels rise. Eosinopenia occurs with corticosteroid administration and is also frequent with active bacterial and viral infections. In patients with eosinophilia of various etiologies, circulating blood eosinophils can exhibit morphologic and functional changes consequent to their activation. In some, but not necessarily all patients with sustained blood eosinophilia, organ damage can develop, especially cardiac, as found in the idiopathic hypereosinophilic syndrome. Undoubtedly, the development of such complications of sustained eosinophilia reflects not just heightened numbers of eosinophils but also some activating events, as yet ill defined, that promote eosinophil-mediated tissue damage. Patients with sustained eosinophilia should be monitored for evidence of cardiac disease (see below). Eosinophilia is not elicited by infections with single-celled protozoan parasites (with the exception of the intestinal coccidian parasite Isospora belli [see Chapter 429]), but rather by the multicellular helminthic parasites. The level of eosinophilia tends to parallel the magnitude and extent of tissue invasion, especially by larvae. Eosinophilia may be absent in established infections that are well contained within tissues or solely intraluminal in the gastrointestinal tract. Even with severe helminthic diseases such as disseminated strongyloidiasis (see Chapter 433), superimposed bacterial infections can suppress eosinophilia. In evaluating a patient with unexplained eosinophilia, geographic and dietary histories are germane in indicating potential exposure to helminthic parasites. Stool examinations for diagnostic ova and larvae should be performed, and for evaluation of Strongyloides infection, an enzyme-linked immunosorbent assay for antigens should be performed. Hence negative stool examinations do not necessarily exclude a helminthic etiology for eosinophilia, and examination of blood or appropriate tissue biopsy material, as guided by the clinical findings and exposure history, may be needed to diagnose specific tissue or blood-dwelling infections, including trichinosis, filarial infections, and in children, visceral larva migrans. The characteristic response in acute bacterial and viral infections is eosinopenia, although in the convalescent phase of these diseases eosinophil numbers return to normal and at times to above normal, as seen with scarlet fever. Two fungal diseases may be associated with eosinophilia: aspergillosis (see Chapter 401), but only in the form of allergic bronchopulmonary aspergillosis and not as invasive disease; and coccidioidomycosis (see Chapter 395), following primary infection, especially in conjunction with erythema nodosum and at times with progressive disseminated disease. On occasion, eosinophilia may be present in chronic tuberculosis (see Chapter 358). Allergic rhinitis and asthma (see Chapters 74 and 274) are commonly associated with eosinophilia. Hypersensitivity drug reactions can elicit eosinophilia without accompanying manifestations such as drug fever or organ dysfunction. Drug-induced interstitial nephritis (see Chapter 107) may be accompanied by blood eosinophilia and eosinophils in the urine. Idiopathic hypereosinophilic syndrome is a myeloproliferative disease characterized by sustained overproduction of eosinophils. The three diagnostic criteria for this disorder are (1) eosinophilia in excess of 1500/muL persisting for longer than 6 months; (2) lack of an identifiable parasitic, allergic, or other etiology for eosinophilia; and (3) signs and symptoms of organ involvement. Not all patients with prolonged eosinophilia develop organ involvement, and many have benign courses.

Taking this leukocyte heterogeneity into account women's health health magazine buy discount lady era 100 mg line, patients may be severely neutropenic or lymphocytopenic despite having total white blood counts that fall within the normal range breast cancer her2 purchase genuine lady era. Because the normal range in blacks and Yemenite Jews is somewhat lower women's health clinic pueblo co discount lady era 100 mg with visa, neutropenia in these populations is defined as counts less than 1 menstrual quotes discount 100mg lady era amex. The role of the neutrophil in phagocytic defense of the host is generally met if the neutrophil count is above 1. The multiple pathophysiologic types of neutropenia are best described in the context of normal neutrophil kinetics. Such a description also simplifies initial diagnostic and therapeutic approaches to patients with neutropenia. Neutrophils arise from a pool of marrow precursor cells through serial divisions and synchronous maturation steps. The rate of neutrophil production is astonishingly high, more than 1011 cells/day. In the bone marrow, neutrophil precursors that retain replicative potential (myeloblasts, promyelocytes, and myelocytes) comprise the mitotic pool. Later differentiation stage cells (metamyelocytes, bands, and segmented neutrophils) do not replicate and therefore form a non-mitotic precursor pool. An additional pool of fully developed neutrophils form a neutrophil storage pool, a population of cells held in reserve ready for release when needed to combat microbial invaders. Released after a few days in the bone marrow, neutrophils circulate freely for only a matter of hours before crawling into the extravascular space looking for things to engulf and kill. Half of the neutrophils in the peripheral blood are "marginated" along the endothelium and are, therefore, not measured in the white blood cell count. Accordingly, the true intravascular neutrophil number, consisting of the circulating and the marginated pools, is ordinarily twice that measured by the neutrophil count. Taking these kinetic considerations into account, a simple pathophysiologic classification 920 Figure 172-1 Production and distribution of neutrophils involve three generic compartments: the marrow, peripheral blood, and extravascular space. Unlike red cells, phagocytes of all kinds are destined to function primarily in the extravascular space. The critical issue for clinicians to consider, therefore, is whether the delivery of phagocytes to this space is adequate. Once more differentiated cells reach the intermediate maturation stage known as the metamyelocyte, they stop proliferating but continue differentiating to bands and segmented neutrophils. Half of these circulating cells adhere to endothelial cells and compose the "marginated pool" (MaP). After their very brief sojourn in the peripheral blood, the neutrophils invade the extravascular compartments of most organs, where they are used as defenders or garbage disposal devices (a process that involves both destruction of the offending organism and self-destruction), or they die within 1 to 2 days. Bone marrow defects (failure to produce and release neutrophils at a normal rate) account for the majority of neutropenias in clinical practice. Failure of the marrow compartment can occur as a result of direct injury, in which case the marrow usually contains fewer than normal hematopoietic cells, or from maturation defects of hematopoietic cells, principally characterized by normal or increased numbers of morphologically abnormal hematopoietic cells. In either case, neutropenia of this type frequently occurs along with abnormalities in the number of platelets and red cells. Marrow injury can occur as a consequence of a variety of diseases, but drug-induced injury is most common (Table 172-1). Antineoplastic and immunosuppressive agents are generally designed to inflict injury on a proliferative population of cells. Drugs that usually are not myelosuppressive and well tolerated in the majority of patients can sometimes induce either marrow injury or peripheral neutrophil destruction. These drug-induced reactions can result from direct drug-mediated cytotoxicity or from an immune mechanism in which (1) neutrophils are destroyed in extramedullary sites as a result of antineutrophil antibodies. Radiation (see Chapter 19) may result in acute self-limited bone marrow injury and chronic marrow failure. Chronic radiation-induced injury can also result in the later development of myelodysplasia and non-lymphocytic leukemia, both of which may present with neutropenia. Benzene toxicity can also result in acute or chronic neutropenia and, like radiation-induced marrow failure, is associated with a high risk of acute non-lymphocytic leukemia. Immune-mediated bone marrow failure can be mediated by autoantibodies or by T lymphocytes that inhibit the growth of bone marrow precursor cells.
