Blanka Rihova was honoured for her work on the infuence of physical vascu lar therapy on the experimental T-cell lymphoma in mice. Joachim Piatkowski was honoured for his excellent observation study with patients using Physical Vascular Therapy. The lymphatic system includes your bone marrow, tonsils, adnoids, spleen, thymus, lymph nodes, and lymphatic vessels which are a web of very thin tubes that lay just beneath the surface of your skin. It is an independent circulatory system that works in partnership with your blood circulatory system as well as your immune system. Your lymphatic system provides a variety of immune functions that ward off infections, viruses, injury and even cancer. The body has around 600 to 700 of these nodes concentrated in the groin, neck, armpits, around the heart, lungs, and intestines. It is important to emphasize that unlike blood circulation (propelled by the pumping action of the heart in many directions), lymphatic fluid flows primarily upwards towards the neck. Through movement, lymph fluid circulates and is able to do its many vital functions. There are a variety of self-help techniques you can do on a regular basis to keep your lymph system healthy and functioning efficiently. The 4 ways listed below can mostly all be done at home, although some special equipment (as outlined) may need to be purchased. The main lymph vessels run up the legs, arms, and torso so moving these areas will move the most lymph. Studies show that daily moderate exercise significantly reduces recurrence risk for breast cancer, in part due to its effect on the lymphatic system. Fortunately, exercise and physical activity come in many forms: Activities such as dancing, gardening, climbing stairs, physical labor, household chores and others that require movement and the contraction and relaxation of muscles. Pick something that you enjoy doing such as cycling, dancing, gardening, tennis, or golf. Consider finding a walking or exercise partner to make it fun and to hold one another accountable. Above all, it is important to make movement a regular part of your daily routine, just as you would eating and sleeping well. Jack Shields, a prominent lymphologist, conducted a study in 1979 that showed deep diaphragmatic breathing causes the lungs to press into the thoracic duct (after its purification by lymph nodes etc. This relieves the pressure off of millions of check valves throughout the entire system. Deep diaphragmatic breathing facilitates movement of lymph through the bloodstream and dramatically increases the elimination of toxins. Exhaling for twice as long as inhaling brings oxygen to the blood and activates the lymphatic system. Perform deep diaphragmatic breathing two or three times a session, three times a day. Because lymph fluid mostly runs vertically, certified lymphologists and reboundologists (yes, it is a real term) believe that vertical motion exercises such as rebounding are more effective for lymphatic actuation than horizontal motion exercises, such as walking, jogging or biking. Vertical movements are perceived to be particularly effective in pumping lymph fluid because of the continuous contraction and subsequent relaxation of muscles, and the continuous compression and release of the connective tissues, and tissue spaces. It is with millions of one-way check valves that lymphatic fluids are kept moving in a consistent one-way direction. The benefits of rebounding include: Activating lymphatic vessels while massaging vital organs and tissues, strengthening bones, and invigorating bone marrow Very little stress on the bones and joints (when using a therapeutic rebounder) Strengthening the tissues of the entire body including the heart muscle Facilitating profound body detoxification Encouraging deep breathing Actuating brain lymph and cerebral spinal fluid renewal Converting mechanical motion into electrical energy in the body for the magnification of thought waves, and boosting the endocrine system Rebounding is fun and is not complicated. Bounce gently, run in place, dance, jump, perform jumping jacks (be sure you have adequate clearance); anything will do the job. Try to make this a daily habit or at least four or five times a week alternating with other movement activities.

The committee has endeavored to express its judgments as clearly and precisely as the data allow acne blemishes discount eurax 20gm overnight delivery. Full text was then obtained for any articles that were considered potentially rel evant based on their titles and abstracts and after applying the inclusion and ex clusion criteria acne hormones order eurax 20gm online. Full-text articles were distributed among the committee members based on their areas of expertise skin care help generic eurax 20gm overnight delivery, with at least two committee members reviewing each paper skin care hospital in chennai purchase eurax 20gm online. Because of the variability in the descriptions and diagnoses of the health conditions considered in this report acne 2000 buy eurax with a visa, the committee made no a priori assumptions about the usefulness of any article or report for a health outcome acne coat purchase eurax 20 gm with visa. Each study was reviewed and objectively evaluated for each health outcome it presented. If a study examined more than one health outcome, it was considered separately for each of those outcomes. After reading, if the full text revealed that the study met one of the exclusion criteria (see Box 3-2), it was excluded from further consideration. After review of the full text of the identifed articles, studies that were con sidered relevant (165 epidemiologic studies and nearly 100 toxicologic studies) were discussed and evaluated thoroughly, and are included in this report. An epidemiologic study was also clas sifed as secondary if the outcome was a biologic marker of effect as opposed to a recognized condition or disease. Mechanistic and toxicologic studies contributed to the evidence for biologic plausibility but were not considered primary studies, so that based on those studies alone, their weight would not be enough to change the level of evidence of an association. The toxicologists on the committee provided a summary of previous and new mecha nistic or toxicologic studies for that health outcome. When drafting language for a conclusion, the committee considered the nature of the exposures, the nature of the specifc health outcome, the populations exposed, and the quality of the evidence examined. The draft text was reviewed and discussed in further plenary sessions until all committee members reached a consensus on the description of the studies and the conclusion for each health outcome. The committee did not use a formulaic approach to determining the number of primary or supporting studies that would be necessary to assign a specifc category of association. If no new primary studies for a health outcome were identifed, the evidence table from Update 2014 was included. Effect estimates, data, and units of measure are presented as reported in the cited studies, except where otherwise noted. The committee did not collect original data, nor did it perform any secondary data analyses, such as meta-analyses. Epidemiologic studies effectively integrate any results of exposure to a target substance in combination with other substances that may be etiologically relevant. Several types of epidemiologic studies were evaluated, including cohort, case-control, and cross-sectional designs. The committee weighed the importance of the epidemiologic studies in the following order: Vietnam veterans, occupationally exposed workers, and people who were exposed environmentally. Including these more highly exposed populations had the additional advantage that epidemiologic studies of them were likely to have greater statistical power to detect any adverse effects that might occur with exposure. Toxicologic studies, particularly in animal models, are included to inform the understanding of biologic plausibility through the toxicology of the chemicals and their exposure pathways. Instead, having served in Vietnam or participating in the Agent Orange Registry is often considered a proxy of her bicide exposure. Therefore, it is diffcult to quantify the risk of specifc health outcomes when the exposures of the total at-risk population have not been mea sured or estimated. In the absence of actual measures of exposure, comparisons between deployed and non-deployed Vietnam-era veterans are considered the next most relevant comparison. Moreover, in many studies of Vietnam veterans, not all health outcomes of interest were reported (in some cases there were too few cases to report, only specifc health outcomes were of interest, or the veteran population was too young for a particular manifestation). Some occupational and environmental cohorts that received exceptionally high exposures have produced many informative results and provide stronger evidence about health outcomes than studies of Vietnam veterans because the exposures were better characterized and measured sooner relative to the exposure. Moreover, in several studies of chemical-production plant workers, the magnitude and duration of exposure to the chemicals were measured and generally greater than among Vietnam veterans, so the likelihood that any possible health consequences would be manifested was greater. Other populations, such as the Agricultural Health Study, a prospective cohort study of U. For each health outcome, occupational and environmental studies are presented after the studies of Vietnam veterans. Animal and Mechanistic Studies the committee used studies of toxicology data to determine whether there is a plausible biologic mechanism or other evidence of a causal relationship between herbicide exposure and a health effect. A positive statistical association between an exposure and an outcome does not necessarily mean that the exposure is the cause of that outcome. Data from toxicology studies may support or confict with a hypothesis that a specifc chemical can contribute to the occurrence of a particular disease. Insights about biologic processes inform whether an observed pattern of statistical association might be interpreted as the product of more than error, bias, confounding, or chance. Discussions on biologic plausibility are presented after new epidemiologic evidence and before the synthesis of all the evi dence. The degree of biologic plausibility itself infuences whether the committee perceives positive fndings to be indicative of a pattern or the product of statistical fuctuations. Ultimately, the results of the toxicology studies should be consistent with what is known about the human disease process if they are to support a conclusion that the development of the disease was infuenced by an exposure. Limitations of Animal Models Animal models are the basis for many of the toxicologic and mechanistic studies, although cell lines and in vitro cell cultures (human or animal) are also used. Studies that use isolated cells in culture also can elucidate how a chemical alters cellular processes. The objectives of those toxi cology studies are to determine what toxic effects are observed at different ex posure levels and to identify the mechanisms by which the effects are produced. To be considered an acceptable surrogate for the study of a human disease, an animal model must reproduce, with some degree of fdelity, the manifesta tions of the disease in humans. However, a given effect of an exposure in an animal species does not necessarily establish its occurrence in humans, nor does the apparent absence of a particular effect in animals mean that the effect could not occur in humans. In addition to possible species differences, many factors affect the ability to extrapolate results from animal studies to health effects in humans. For example, animals used in experimental studies are most often exposed to purifed chemicals, not to mixtures. Even if herbicide formulations or mixtures are used, the conditions of exposure might not realistically repro duce the human exposures that occur in the feld. Other variables, including the amount and duration of exposure, can be controlled precisely in laboratory settings. Although the degree of susceptibility is generally thought to be an inherent biological response, it can be infuenced by life stage, past history, and co-exposures. Many factors may contribute to differences between the results of controlled animal studies and the effects observed in humans. Depending on the biologic process under investigation, a particular test species may match the human system more closely and so be a better experimental model than others. The route of exposure by which an exogenous agent enters an organism may infuence the nature of any toxic response elicited. There are well-known differences between male and female animals (including humans) in susceptibility to xenobiotic expo sures, some of which are modifed by sex steroids. Humans are ex posed to xenobiotics from multiple sources throughout their lifetimes. Most xenobiotic exposures occur in complex mix tures; the makeup of these mixtures can heavily infuence the ultimate toxic effects. In addition to the dietary modulation of responses to other exposures of both humans and animals, including dietary supplements in humans, prescription and over-the-counter pharmaceuticals, and other factors (such as cigarette smoking and ambient pollution) may have effects. For example, the current committee included chronic skin conditions, which had not specifcally been addressed by prior committees. Comments received at public hearings and in written submissions from veterans and other interested persons have been valuable in identifying issues to be pursued to greater depth in the scientifc literature. In aggregate, the health outcomes that the committee has focused on include cancers of all types, cardiovascular and metabolic outcomes such as diabetes, immune system disorders, and neurologic disorders. Other chronic health out comes have also been considered, including respiratory disorders, gastrointestinal disorders, endocrine disorders, and bone conditions. Although for most health outcomes the primary focus of the evaluation was on adverse outcomes in the veterans themselves, to examine potential effects, the children of Vietnam veterans and also later generations were included in the evaluation of the literature. After reviewing the updated literature, the committee agreed that some reor ganization of the health conditions was warranted for this volume. Because any effect of the herbicides or contaminants in individuals or groups of veterans is evaluated in terms of disease or medical outcome, the committee paid particular attention to disease diagnosis and classifcation as it assembled pertinent data from various investigations related to a particular outcome in prepa ration for integrating the information. Self-reported diagnoses obtained from survey ques tionnaires often have inaccuracies due to recall bias and misinterpretations of the questions being asked. For example, a patient may report having been treated for stomach cancer when the correct diagnosis was gastric adenocarcinoma, gastric lymphoma, or peritoneal cancer. Sometimes this is done because there are few cases of a specifc outcome and the study is lacking the necessary statistical power to make valid statistical associations using such specifc diagnoses. How ever, such grouping into broader outcome categories can be problematic (and the same is true when categorizing potential exposure). Therefore, if a report indicated that a cohort has an increased incidence of digestive system cancers, then it would be unclear whether the association was attributable to excess cases of any single organ or type or to some combina tion thereof. Additionally, such generalization is complicated by the fact that the cause of cancer may differ among anatomic sites. For instance, there are strong associations between smoking and squamous cell carcinoma of the esophagus and between chronic hepatitis B infection and hepatic cancer. Furthermore, a single site may experience a carcinogenic response to multiple agents, while the same agent may cause cancer at multiple sites. This can also be an issue in mortal ity studies when more than the primary cause of death is used. Designing studies to analyze concurrent health outcomes is much more diffcult, and valid methods that can be applied with confdence to identify patterns among multiple health outcomes associated with a single exposure have not yet been developed. Defning Statistical Association Box 3-3 provides brief defnitions of some of the most common terms used in the epidemiologic studies considered by this committee. The strength of an as sociation between exposure and a condition is generally estimated quantitatively by using relative risks, odds ratios, correlation coeffcients, or hazard ratios, depending on the epidemiologic design used. Determining whether an estimated association between an exposure and an outcome represents a real relationship requires careful scrutiny because there can be more than one explanation for an estimate. There are several types of biases, and each type may affect the estimate differently. For example, misclassifcation bias may result in exaggerated or underestimated estimates, whereas self-selection bias af fects the representativeness of the study population and can limit the applicability of the results to the larger population of interest. Another type of bias that may potentially affect studies of Vietnam veterans is detection bias, in which veterans who are encouraged to and who choose to participate in screening programs or registries, such as the Agent Orange Registry (discussed in Chapter 5) may have additional tests or follow-up exams that could potentially detect disease or a con dition earlier or because more thorough assessments were conducted. Incidence is the num ber of new cases of illness during a given period of tim e in a specified population divided by the total population. Prevalence is the num ber of existing cases of an illness or disease in a given population at a specific tim e or within a specified tim e period. Detection bias may lead to an overestimate or underestimate of the true effect size. Potentially, if a confounder is known, there are methods that can be used to adjust for its effects; however, not all con founders are always known or identifed, and unknown confounders may affect the estimate of association. Effect modifca tion occurs when an exposure has a different effect among different subgroups or strata. Chance is the degree to which an estimated association might vary randomly among different samples of the population studied. In the case of epidemiologic studies, exposure to multiple, possi bly toxic, chemicals is common in some industries, such as agriculture, and those exposures cannot be controlled for in the same way that laboratory experiments can. In its examination of these epidemiologic studies, the committee looked for evidence of health effects that are associated with the specifc compounds in the herbicides used in Vietnam and sought consideration of and adjustment for other possibly confounding exposures. Some studies relied on interviews or questionnaires to determine the extent and frequency of exposure. Such self-reported information, which has the potential for recall bias, generally carries less weight than do more objective measures of exposure, such as levels of a contaminant as measured in serum or other biospecimens.

They have a complicated multiring structure containing a lactone ring that is essential for activity. Topotecan is employed in metastatic ovarian cancer when primary therapy has failed and also in the treatment of small-cell lung cancer. Therefore, the dose may have to be modified in patients with impaired kidney function. Frequent peripheral blood counts should be performed on patients taking this drug. Nonhematologic effects include diarrhea, nausea, vomiting, alopecia, and headache. Myelosuppression is also seen with irinotecan, and delayed diarrhea may be severe and require treatment with loperamide. Resistance to topoisomerase inhibitors is conferred either by presence of the multidrug-resistant P-glycoprotein or by mutation of the enzyme. Etoposide finds its major clinical use in the treatment of oat-cell carcinoma of the lung and in combination with bleomycin and cisplatin for testicular carcinoma. Teniposide is used as a second-line agent in the treatment of acute lymphocytic leukemia. Despite this, teniposide has shown effectiveness against gliomas and neuroblastomas. Metabolites are converted to glucuronide and sulfate conjugates and are excreted in the urine. Drugs that induce the cytochrome P450 system lead to an acceleration of teniposide metabolism. Dose-limiting myelosuppression (primarily leukopenia) is the major toxicity for both drugs. The ability of imatinib to occupy the a kinase pocketa prevents the phosphorylation of tyrosine on the substrate molecule and, hence, inhibits subsequent steps that lead to cell proliferation. It undergoes metabolism by the cytochrome P450 system to several compounds, of which the N-demethyl derivative is active. Adverse effects include fluid retention and edema, hepatotoxicity, thrombocytopenia or neutropenia, as well as nausea and vomiting. At least five metabolites have been identified, only one of which has significant antitumor activity. A rare but potentially fatal adverse effect is interstitial lung disease, which presents as acute dyspnea with cough. Bone marrow depression is the major toxicity, and nausea, vomiting, and diarrhea are common. The drug is also neurotoxic, causing symptoms ranging from drowsiness to hallucinations to paresthesias. Because it inhibits monoamine oxidase, patients should be warned against ingesting foods that contain tyramine (for example, aged cheeses, beer, and wine). Its mechanism of action is based on the fact that some neoplastic cells require an external source of asparagine because of their limited capacity to synthesize sufficient amounts of that amino acid to support growth and function. L-Asparaginase hydrolyzes blood asparagine and, thus, deprives the tumor cells of this amino acid, which is needed for protein synthesis (Figure 39. Resistance to the drug is due to increased capacity of tumor cells to synthesize asparagine. Toxicities include a range of hypersensitivity reactions (because it is a foreign protein), a decrease in clotting factors, liver abnormalities, pancreatitis, seizures, and coma due to ammonia toxicity. Mechanism of action: Interferons secreted from producing cells interact with surface receptors on other cells, at which site they exert their effects. As a consequence of the binding of interferon, a series of complex intracellular reactions take place. These include synthesis of enzymes, suppression of cell proliferation, activation of macrophages, and increased cytotoxicity of lymphocytes. Pharmacokinetics: Interferons are well absorbed after intramuscular or subcutaneous injections. Interferons undergo glomerular filtration and are degraded during reabsorption, but liver metabolism is minimal. The rationale for administering the coenzyme depends on it being essential for: A. Administration of which one of the following agents would accelerate recovery of neutrophil counts Overview the importance of the immune system in protecting the body against harmful foreign molecules is well recognized. For example, the introduction of an allograft (that is, the graft of an organ or tissue from one individual to another who is not genetically identical) can elicit a damaging immune response, causing rejection of the transplanted tissue. Transplantation of organs and tissues (for example, kidney, heart, or bone marrow) has become routine due to improved surgical techniques and better tissue typing. Also, drugs are now available that more selectively inhibit rejection of transplanted tissues while preventing the patient from becoming immunologically compromised (Figure 40. Earlier drugs were nonselective, and patients frequently succumbed to infection due to suppression of both the antibody-mediated (humoral) and cell-mediated arms of the immune system. Today, the principal approach to immunosuppressive therapy is to alter lymphocyte function using drugs or antibodies against immune proteins. Because of their severe toxicities when used as monotherapy, a combination of immunosuppressive agents, usually at lower doses, is generally employed. Both Signals 1 and 2 activate several intracellular signal transduction pathways, one of which is the calcium-calcineurin pathway, which is targeted by cyclosporine and tacrolimus. Immunosuppressive drugs can be categorized according to their mechanisms of action: 1) Some agents interfere with cytokine production or action; 2) others disrupt cell metabolism, preventing lymphocyte proliferation; and 3) mono and polyclonal antibodies block T-cell surface molecules. Selective Inhibitors of Cytokine Production and Function Cytokines are soluble, antigen-nonspecific, signaling proteins that bind to cell surface receptors on a variety of cells. These cytokines collectively activate natural killer cells, macrophages, and cytotoxic T lymphocytes. CsA is used to prevent rejection of kidney, liver, and cardiac allogeneic transplants. CsA is most effective in preventing acute rejection of transplanted organs when combined in a double-drug or triple-drug regimen with corticosteroids and an antimetabolite such as mycophenolate mofetil. CsA is an alternative to methotrexate for the treatment of severe, active rheumatoid arthritis. It can also be used for patients with recalcitrant psoriasis that does not respond to other therapies. Mechanism of action: Cyclosporine preferentially suppresses cell-mediated immune reactions, whereas humoral immunity is affected to a far lesser extent. After diffusing into the T cell, CsA binds to a cyclophilin (more generally called an immunophilin) to form a complex that binds to calcineurin (Figure 40. Pharmacokinetics: Cyclosporine may be given either orally or by intravenous infusion. Half of this is in the erythrocytes, and less than one-tenth is bound to the lymphocytes. Excretion of the metabolites is through the biliary route, with only a small fraction of the parent drug appearing in the urine. Adverse effects: Many of the adverse effects caused by CsA are dose dependent; therefore, it is important to monitor blood levels of the drug. Lymphoma may occur in all transplanted patients due to the net level of immunosuppression and has not been linked to any one particular agent. Other toxicities include hypertension, + hyperlipidemia, hyperkalemia (it is important not to use K sparing diuretics in these patients), tremor, hirsutism, glucose intolerance, and gum hyperplasia. An ointment preparation has been approved for moderate to severe atopic dermatitis that does not respond to conventional therapies. Absorption is decreased if the drug is taken with high-fat or high-carbohydrate meals. Renal excretion is very low, and most of the drug and its metabolites are found in the feces. Development of posttransplant, insulin-dependent diabetes mellitus is a problem, especially in black and Hispanic patients. Other untoward problems are headache, nausea and diarrhea, leukopenia, and thrombocytopenia. Because of their rapid proliferation in the immune response and their dependence on the de novo synthesis of purines required for cell division, lymphocytes are predominantly affected by the cytotoxic effects of azathioprine. Concomitant use with angiotensin-converting enzyme inhibitors or cotrimoxazole in renal transplant patients can lead to an exaggerated leukopenic response. Allopurinol, an agent used to treat gout, significantly inhibits the metabolism of azatihioprine; therefore, the dose of azathioprine must be reduced by 60 to 75 percent. The most common adverse effects include diarrhea, nausea, vomiting, abdominal pain, leukopenia, and anemia. Antibodies the use of antibodies plays a central role in prolonging allograft survival. They are prepared either by immunization of rabbits or horses with human lymphoid cells (producing a mixture of polyclonal antibodies directed against a number of lymphocyte antigens), or by hybridoma technology (producing antigen-specific, monoclonal antibodies). Hybrid cells are selected and cloned, and the antibody specificity of the clones is determined. Clones of interest can be cultured in large quantities to produce clinically useful amounts of the desired antibody. The polyclonal antibodies, although relatively inexpensive to produce, are variable and less specific, which is in contrast to monoclonal antibodies, which are homogeneous and specific. Antithym ocyte globulins Thymocytes are cells that develop in the thymus and serve as T-cell precursors. The antibodies developed against them are prepared by immunization of large rabbits or horses with human lymphoid cells and, thus, are polyclonal. They are primarily employed, together with other immunosuppressive agents, at the time of transplantation to prevent early allograft rejection, or they may be used to treat severe rejection episodes or corticosteroid-resistant acute rejection. Rabbit formulations of polyclonal antithymocyte globulin are more commonly used over the horse preparation due to greater potency. The antibodies bind to the surface of circulating T lymphocytes, which then undergo various reactions, such as complement-mediated destruction, antibody-dependent cytotoxicity, apoptosis, and opsonization. The antibody-bound cells are phagocytosed in the liver and spleen, resulting in lymphopenia and impaired T-cell responses. The antibodies are slowly infused intravenously, and their half-life extends from 3 to 9 days. Because the humoral antibody mechanism remains active, antibodies can be formed against these foreign proteins. It is also used to deplete T cells from donor bone marrow prior to transplantation. Circulating T cells are depleted; thus, their participation in the immune response is decreased. It is therefore customary to premedicate the patient with methylprednisolone, diphenhydramine, and acetaminophen to alleviate the cytokine release syndrome. The symptoms can range from a mild, flu-like illness to a life-threatening, shock-like reaction. Central nervous system effects, such as seizures, encephalopathy, cerebral edema, aseptic meningitis, and headache, may occur. The serum half-life of daclizumab is about 20 days, and the blockade of the receptor is 120 days. No clinically relevant antibodies to the drugs have been detected, and malignancy does not appear to be a problem. Alemtuzumab is currently approved for the treatment of refractory B-cell chronic lymphocytic leukemia. Preliminary results are promising, with low rates of rejection with a prednisone-free regimen. Side effects include first-dose cytokine release syndrome, requiring premedication with acetaminophen, diphenhydramine, and corticosteroids.

Normal values range from approximately 30% to 45%, depending on age16 See more information on echocardiography on Expert Consult, Chapter 7. Common causative organisms: About 70% of causes of endocarditis are streptococcal species (Streptococcus viridans, enterococci); 20% are staphylococcal species (Staphylococcus aureus, Staphylococcus epidermidis); 10% are other organisms (Haemophilus infuenzae, gram-negative bacteria, fungi) 2. Clinical fndings: New heart murmur, recurrent fever, splenomegaly, petechiae, fatigue, Osler nodes (tender nodules at fngertips), Janeway lesions (painless hemorrhagic areas on palms or soles), splinter hemorrhages, and Roth spots (retinal hemorrhages) B. All dental procedures that involve treatment of gingival tissue or periapical region of the teeth or oral mucosal perforation 2. Invasive procedures that involve incision or biopsy of respiratory mucosa, such as tonsillectomy and adenoidectomy 3. Not recommended for genitourinary or gastrointestinal tract procedures; solely for bacterial endocarditis prevention See Table 7-15 and Box 7-4. Etiology: Infectious, toxic (alcohol, anthracyclines), metabolic (hypothyroidism, muscular dystrophy), immunologic, collagen vascular disease, nutritional defciency (kwashiorkor, beriberi) b. Echocardiography: Enlarged ventricles (increased end-diastolic and end-systolic dimensions) with little or no wall thickening; decreased shortening fraction g. Hypertrophic cardiomyopathy: Abnormality of myocardial cells leading to signifcant ventricular hypertrophy, particularly of the left ventricle, with small to normal ventricular dimensions. Increased contractile function, but impaired flling secondary to stiff ventricles. Etiology: Genetic (autosomal dominant, 60% of cases) or sporadic (40% of cases) b. Symptoms: Easy fatigability, anginal pain, shortness of breath, occasional palpitations c. Echocardiography: Extent and location of hypertrophy, obstruction, increased contractility g. Treatment: Moderate restriction of physical activity, administration of negative inotropes (-blocker, calcium channel blocker) to help improve flling and subacute bacterial endocarditis prophylaxis. Restrictive cardiomyopathy: Myocardial or endocardial disease (usually infltrative or fbrotic) resulting in stiff ventricular walls, with restriction of diastolic flling but normal contractile function. Diuretics, anticoagulants, calcium channel blockers, pacemaker for heart block, cardiac transplantation if severe 4. Variably anorexia, lethargy, emesis, lightheadedness, cold extremities, shortness of breath c. Echocardiography: Enlargement of heart chambers, impaired left ventricular function h. May require heart transplantation if no improvement (about 20% to 25% of cases) D. Symptoms: Chest pain (retrosternal or precordial, radiating to back or shoulder, pleuritic in nature, alleviated by leaning forward, aggravated by supine position), dyspnea c. Etiology: Associated with acute pericarditis (exudative fuid) or serous effusion resulting from increased capillary hydrostatic pressure. Symptoms: Can present with no symptoms, dull ache in left chest, abdominal pain, or symptoms of cardiac tamponade, discussed subsequently c. Examination: Muffed distant heart sounds, dullness to percussion of posterior left chest (secondary to atelectasis from large pericardial sac), hemodynamic signs of cardiac compression d. Echocardiography shows extent and location of hypertrophy, obstruction, increased contractility g. Observe if asymptomatic; use pericardiocentesis if there is sudden increase in volume or hemodynamic compromise. Nonsteroidal anti-infammatory drugs or steroids may be of beneft, depending on etiology 3. Cardiac tamponade: Accumulation of pericardial fuid under high pressure, causing compression of cardiac chambers, limiting flling, and decreasing stroke volume and cardiac output a. Most commonly associated with viral infection, neoplasm, uremia, and acute hemorrhage b. Examination: Jugular venous distention, hepatomegaly, peripheral edema, tachypnea, rales (from increased systemic and pulmonary venous pressure), hypotension, tachycardia, pulsus paradoxus (decrease in systolic blood pressure by >10 mmHg with each inspiration), decreased capillary refll (from decreased stroke volume and cardiac output), quiet precordium, and muffed heart sounds d. Echocardiography: Right ventricle collapse in early diastole, right atrial/ left atrial collapse in end-diastole and early systole f. Treatment: Pericardiocentesis with temporary catheter left in place if necessary (see Chapter 3), pericardial window or stripping if it is a recurrent condition E. Kawasaki Disease Leading cause of acquired heart disease in children in developed countries. Patients present with acute febrile vasculitis, which may lead to long-term cardiac complications from vasculitis of coronary arteries. Thought to be immune-regulated, in response to infectious agents or environmental toxins 2. These include high fever lasting 5 days or more, plus at least four of the following fve criteria: a. Other clinical fndings: Often associated with extreme irritability, abdominal pain, diarrhea, vomiting. Also seen are anterior uveitis (80%), arthritis and arthralgias (35%), aseptic meningitis (25%), pericardial effusion or arrhythmias (20%), gallbladder hydrops (<10%), carditis (<5%), and perineal rash with desquamation 4. Subacute phase (11 to 25 days after onset of illness): Resolution of fever, rash, and lymphadenopathy. Cardiovascular complications: If untreated, 15% to 25% develop coronary artery aneurysms and dilation in subacute phase (peak prevalence occurs about 2 to 4 weeks after onset of disease; rarely appears after 6 weeks) and are at risk for coronary thrombosis acutely and coronary stenosis chronically. Aspirin is recommended for both its anti-infammatory and its antiplatelet effects. Follow-up: Serial echocardiography is recommended to assess coronary arteries and left ventricular function (at time of diagnosis, at 2 weeks, at 6 to 8 weeks, and at 12 months [optional]). More frequent intervals and long-term follow-up are recommended if abnormalities are seen on echocardiography. Etiology: Believed to be immunologically mediated delayed sequela of group A streptococcal pharyngitis 2. Clinical fndings: History of streptococcal pharyngitis 1 to 5 weeks before onset of symptoms.

Introduction: eligibility recommendations for competitive athletes with cardiovascular abnormalities. Prevention of infective endocarditis: guidelines from the American Heart Association: a guideline from the American Heart Association Rheumatic Fever, Endocarditis, and Kawasaki Disease Committee, Council on Cardiovascular Disease in the Young, and the Council on Clinical Cardiology, Council on Cardiovascular Surgery and Anesthesia, and the Quality of Care and Outcomes Research Interdisciplinary Working Group. Recommendations and considerations related to preparticipation screening for cardiovascular abnormalities in competitive athletes: 2007 update: a scientifc statement from the American Heart Association Council on Nutrition, Physical Activity, and Metabolism: endorsed by the American College of Cardiology foundation. Macule/patch: Small fat lesion with altered color (<1 cm); large macule (>1 cm) 2. Papule/plaque: Elevated, well-circumscribed lesion (<1 cm); large papule (>1 cm) 3. Nodule/tumor: Mass located in dermis or subcutaneous fat (may be solid or soft); large nodule 4. Wheal: Erythematous, well-circumscribed, raised, edematous lesion that appears and disappears quickly B. Crust: Exudative mass consisting of blood, scale, and pus from skin erosions or ruptured vesicles/papules 4. Scar: Formation of new connective tissue after damage to epidermis and cutis, leaving permanent change in skin 6. Pathogenesis A benign vascular tumor of infancy with a phase of rapid proliferation followed by spontaneous involution. During proliferative phase, densely packed endothelial cells form small capillaries; subsequent vessels develop from existing vasculature. Appearance: (1) Newborns may demonstrate pale macules with threadlike telangiectasias (2) Most recognizable form is a bright red, slightly elevated, noncompressible plaque. Frequently, both superfcial and deep components are present, with deep components appearing bluish in color (3) Size: Can range from a few millimeters to several centimeters b. Incidence: Most common soft tissue tumors in infancy, with increased incidence in premature infants; three times more likely in girls than boys c. Ulceration: Most common complication; may result in severe pain, infection, hemorrhage, or scarring; ulceration results from necrosis of superfcial components. Hemorrhage, although alarming in appearance, is usually minimal and can be controlled by direct pressure. Kasabach-Merritt phenomenon: A complication of rare hemangiopericytoma, tufter angiomas, or Kaposiform hemangioendotheliomas which rapidly enlarge, and are usually deep lesions; characterized by anemia, thrombocytopenia, and coagulopathy, requiring aggressive medical management. Lesions are differentiated from benign hemangiomas by their deep red-blue appearance, marked frmness, and histologic appearance c. Regionally important lesions: (1) Periorbital lesions: May cause amblyopia from obstruction of the visual axis or astigmatism from insidious compression of the globe or extension into the retrobulbar space. Require careful observation and evaluation by an ophthalmologist (2) External auditory canal lesions: May result in otitis or conductive hearing loss (3) Multiple cutaneous hemangiomas and large facial hemangiomas, especially segmental hemangiomas, are associated with visceral hemangiomas and may warrant abdominal ultrasound to look for organ involvement. Large facial hemangiomas are also associated with posterior fossa vascular malformations, and thus patients should have neuroimaging with special attention to the posterior fossa (5) Airway hemangiomas: Often located in the subglottic region; may cause hoarseness and stridor. Infants with cutaneous lesions in a beard distribution (chin, lips, mandibular region, and neck) are at greatest risk for airway involvement (6) Lumbosacral hemangiomas that span the midline are associated with spinal malformations, dysraphism, and anomalies of the anorectal and urogenital regions. An ultrasound of the L5 spine in infants <6 months of age is an effective noninvasive screening study 4. Decision to treat should be based on location and depth of the lesion, age of patient, and likelihood of complication. Systemic corticosteroids previously was the mainstay of therapy to prevent subsequent complication. One third of lesions demonstrate dramatic shrinkage, one third demonstrate stabilization of growth, and one third show no response c. Younger infants tend to have a longer treatment course secondary to higher rates of recurrence d. Embolization: Can be used to treat cutaneous hemangiomas that have not responded to medical therapy g. The virus enters the skin through breaks in the epithelium, causing hyperplasia of the squamous epithelium 2. Common warts: Lesions are skin-colored, rough, minimally scaly papules and nodules found on the exposed surfaces of the hands, face, arms, and legs. Lesions can be solitary or multiple, a few millimeters to several centimeters in diameter, and may form large plaques or a confuent, linear pattern secondary to autoinoculation b. Plantar warts: Found on the soles of the feet as sometimes painful but often asymptomatic, inward-growing, hyperkeratotic plaques and papules. Trauma on weight-bearing surfaces results in small black dots (seeds from thrombosed vessels on the surface of the wart) d. Particularly effective in combination with adhesive tape occlusion; response may take 4 to 6 months c. Morphology (Color Plate 1): Caused by the pox virus; consists of dome-shaped, often umbilicated, translucent to white papules that range from 1 mm to 1 cm, with a tiny keratotic core at the center. They may appear infamed and secondarily infected when undergoing spontaneous involution.
