Prophylactic antiplatelet therapy should be instituted while the diagnosis is confirmed terramycin 250mg on line should you take antibiotics for sinus infection. While increased bleeding tendency terramycin 250mg with mastercard antibiotics for uti safe for breastfeeding, dietary deficiency, and malabsorption are all true causes of iron deficiency anemia, they are not the culprits during pregnancy. Iron storage is regulated at the level of absorption, and very little of it is lost from the body. Participation in the mitochondrial reaction that produces succinyl-CoA refers to the mechanism of action of one of the natural cobalamins, deoxyadenosylcobalamin. Sideroblastic anemia may develop in alcoholics and patients undergoing anti- tuberculin therapy. Vitamin B12 and folic acid are used for megaloblastic anemias caused by depletion of the vitamin. Loss of vitamin B12 is a very slow process, with hepatic stores being sufficient for up to 5 years. Folic acid supplementation has been shown to decrease the incidence of neu- ral tube defects. Increasing the oxygen-carrying capacity of the blood refers to a possible role of iron supplements. Stimulating myelopoiesis of ery- throid progenitor cells refers to the mechanism of action of erythropoietin. Finally, reduction of blood viscosity during pregnancy refers to pentoxifylline; however, this medication is not recom- mended during pregnancy. Hydroxyurea increases the production of fetal hemoglobin and has been shown to be effective in reducing painful episodes of sickle crisis. Acetaminophen is unlikely to be helpful in this patient’s situation, as this agent is useful for mild-to-moderate pain. Oprelvekin has been shown to reduce the need for platelet transfusions follow- ing myelosuppressive chemotherapy. Leucovorin is used in patients undergoing treatment with methotrexate, to prevent some of its side effects. Heparin releases lipoprotein lipase from vascular beds, which accelerates clearing of lipoproteins from plasma. The clotting factor is inactivated, which releases heparin and allows it to be recycled. Coumarin is commonly used in patients with atrial fibrillation for prevention of thromboembolic events, such as stroke. Prothrombin times should be frequently monitored in patients taking coumarin, as bleeding is a common adverse effect. Fragmin and Lovenox are low-molecular-weight derivatives of hep- arin that do not require laboratory monitoring. The vomiting reflex is a coordinated reflex controlled by a bilateral vomiting center in the dor- sal portion of the lateral reticular formation in the medulla. Pharmacologic intervention relies on inhibition of inputs or depression of the vomiting center. Subjective vertigo is prosyncopal light-headedness, which may be caused by cochlear or ves- tibular ischemia. Cholinergic antagonists reduce the excitability of labyrinthine receptors and depress con- duction from the vestibular apparatus to the vomiting center. Cholinergic antagonists are used to treat motion sickness and in preoperative situations. Cholinergic antagonists produce adverse effects that include drowsiness, dry mouth, and blurred vision. Transdermal delivery of scopolamine via a skin patch decreases the incidence of adverse effects and produces relief for 72 hours. Histamine H1-receptor antagonists include meclizine (Antivert, Bonine), cyclizine (Mare- zine), dimenhydrinate (Dramamine), and promethazine (Phenergan). These agents most likely act by inhibiting histamine pathways, and cholinergic pathways (receptor ‘‘crossover’’) of the vestibular apparatus. Histamine H1-receptor antagonists are used to treat motion sickness and true vertigo. Cyclizine and meclizine are drugs of choice for nausea and vomiting associated with pregnancy. These agents produce sedation and dry mouth and have anticholinergic side effects.

Roy M John Contrary to conventional w isdom , a significant num ber of sudden arrhythm ic deaths result from re-entrant ventricular tachycardia that occurs in patients w ith chronic heart disease in the absence of acute infarction. These arrhythm ias can be safely studied in a controlled setting using electrophysiological testing. In addition, electrophysiological studies can unm ask severe His-Purkinje conduction disease requiring pacem aker im plantation. In these patients, if the clinical suspicion is high, a negative study m ay w ell represent a false negative. Injury to the vascular structures and venous throm bosis occurs rarely (less than 2% ).

Roy M John and Mark Squirrell Studies in the early 1980s show ed that recurrence rates w ere high for patients presenting w ith a m alignant arrhythm ia unrelated to m yocardial ischaem ia or infarction. M ost patients random ised to the antiarrhythm ic arm of the trial w ere treated w ith am iodarone. Unfortunately, such patients have com peting causes for m ortality such as pum p failure and electrom echanical dissociation that are responsible for 50% of deaths. A good place to start is the Am erican College of Cardiology/Am erican Heart Association Practice Guidelines for Arrhythm ia Devices. The cost per life year saved is also w ildly different in these trials giving us conflicting inform ation, e. O ther patients m ust be dealt w ith on a case by case basis w eighing up all the individual circum stances. The Am erican College of Cardiology/Am erican Heart Association practice guidelines for arrhythm ia devices. Im proved survival w ith an im planted defibrillator in patients w ith coronary disease at high risk for ventricular arrhythm ia. A com parison of antiarrhythm ic-drug therapy w ith im plantable defibrillators in patients resuscitated from near-fatal ventricular arrhythm ias. Reprogram m ing of the various param eters that govern pacing, arrhythm ia detection and therapy m ay be necessary from tim e to tim e. Such routine follow up, usually undertaken at established arrhythm ia centres, should occur at 3 to 6 m onthly intervals in the absence of m ajor inter- current events. Som e issues specific to this group of patients can be sum m arised as follow s: 1. O nce this is exceeded for a defined period of tim e, the device m ay deliver therapy irrespective of w hether the arrhythm ia is of ventricular or supra- ventricular origin. Further, if anti- tachycardia pacing is delivered in the ventricle for an atrial arrhythm ia, ventricular arrhythm ias m ay be provoked creating a pro-arrhythm ic situation. Cognisant of the above, it is im perative that atrial arrhythm ias are adequately treated in these patients, particularly the paroxysm al 100 Questions in Cardiology 189 form of atrial fibrillation that is com m only associated w ith rapid rates at its onset. Drugs such as flecainide and am iodarone can increase pacing and defibrillation thresholds. In patients w ith a low m argin of safety for these param eters, use of these drugs m ay result in failure of pacing or defibrillation.
A particular genetic alteration in hypertensive patients dramatically increases the risk of heart attack 250mg terramycin overnight delivery antimicrobial 24, stroke or death order 250mg terramycin with visa infection red line on skin, and may explain why some hypertensive patients fare worse than others, even if they take the same medication. Patients car- rying α-adducin gene are less likely to suffer a heart attack or stroke if they were taking a diuretic. In these individuals, the amino acid glycine has been swapped with the amino acid tryptophan. Up to 40 % of the popu- lation carries at least one copy of the tryptophan form of the gene. Patients with this version had a 43 % higher risk of heart attack, stroke or death than those with the glycine form in the 2½ years after the study began. The findings of this study may enable patients to receive appropriate per- sonalized medicine based on their genetic makeup. Such a test enables the selection of the most effective Universal Free E-Book Store Role of Diagnostics in Personalized Management of Cardiovascular Disease 497 drug as first line treatment leading to reduction of the number of drugs required for adequate treatment as well the number of visits by the patient to the health-care facility for monitoring of blood pressure. The overall effect would be improvements in quality of health care and cost savings. An antihypertensive agent, rostafuroxin, selectively inhibits these mecha- nisms in rodents. The genetic profile defined by these variants predicted the antihypertensive effect of rostafuroxin, a sodium pump blocker, but not that of losar- tan or hydrochlorothiazide. The results open up the possibility of improved patient stratification, as they allow predictions to be made about the effectiveness of rostafuroxin (but not that of any other antihypertensive drugs) in patients carrying key gene variants. Role of Pharmacogenetics in Management of Hypertension Genetic factors may influence the response to antihypertensive medication. A num- ber of studies have investigated genetic polymorphisms as determinants of cardio- vascular response to antihypertensive drug therapy. Hypertensive patients with the 460 W allele of the α-adducin gene have a lower risk of myocardial infarction and Universal Free E-Book Store 498 14 Personalized Management of Cardiovascular Disorders stroke when treated with diuretics compared with other antihypertensive therapies. Although there are controversies to settle and difficulties to overcome, pharmacogenetics may yield successful strategies to optimize drug therapy. Several candidate genes are currently under investigation for their potential to modify response to antihypertensive drugs. Findings from previous studies require confor- mation in other studies to be able to make definitive conclusions about current posi- tive drug-gene interactions. It is also important that research groups collaborate more in order to facilitate the conduct of a metaanalysis for conclusive results. With the development of efficient methods for analyzing massive amounts of data, phar- macogenetic studies may eventually lead to the optimization of antihypertensive drug therapy based on genetic profiles of patients. This will be accomplished through candidate gene and genome-wide association approaches. Subjects are then randomized to either hydrochlo- rothiazide or atenolol, with one dose titration step, followed by assessment of response to therapy after at least 6 weeks on the target dose. Those with blood pres- sure >120/70 mmHg have the second drug added, with similar dose titration and response assessment procedures. This trial will add substantially to our understand- ing of the genetic determinants of antihypertensive and adverse metabolic responses to two commonly used antihypertensive drug classes. Pharmacogenetics of Lipid-Lowering Therapies Cardiovascular disease is associated with nonmodifiable risk factors such as age, gender, and genetic background, and with modifiable risk factors such as lipid con- centrations. Lowering serum lipid levels has been demonstrated to slow the pro- gression of, or even induce regression in, atherosclerosis. Pharmacogenetics provides the experimental basis to understand the variability in response to drugs as a function of the individual genetic makeup. Information from small clinical trials reveals that several candidate genes may hold some promise in our quest to predict individual success to hypolipidemic drug treatment. Polymorphisms in Genes Involved in Cholesterol Metabolism Polymorphisms in genes involved in cholesterol synthesis, absorption, and trans- port may affect statin efficacy. Variation within these genes was then examined for associations with changes in lipid levels observed with pravastatin therapy.

Although its side effect profile is sim ilar best terramycin 250 mg bacteria ua rare, diabetes m ellitus can be a com plication. Azathioprine is an antim etabolite w hose m ajor side effects include bone m arrow suppression and hepatic cholestasis. Som e patients w ho are intolerant of azathioprine are prescribed m ycophenolate m ofetil (w hich is less likely to cause bone m arrow suppression) or cyclophospham ide. At the present tim e the precise role of tacrolim us and m ycophenolate in post-cardiac 130 100 Questions in Cardiology and pulm onary transplant im m unosuppression is unclear and requires further study. In addition to regular m onitoring of drug levels and haem ato- logical (full blood count) and biochem ical (renal and hepatic function, blood glucose) indices, one should be aw are of drug interactions w hich m ay reduce or increase the levels or effectiveness of im m unosuppressive agents.

The dose of azathioprine has to be reduced by 70% if patients are also prescribed allopurinol. The m edical m anagem ent of patients w ith cystic fibrosis follow ing heart-lung transplantation. Brendan Madden Post-transplant cardiac denervation theoretically abolishes the perception of cardiac chest pain. How ever, som e patients m ay develop postoperative typical anginal chest pain precipitated by exercise or by increasing heart rate. Such sym ptom s, how ever, are usually described by patients w ho are m ore than five years follow ing transplantation. Chest pain associated w ith coronary artery disease is uncom m on in patients w ho are less than five years post-cardiac transplantation. Interestingly, recent evidence show s an absence of bradycardic response to apnoea and hypoxia in cardiac transplant recipients w ith obstructive sleep apnoea. It m ay be that prospective overnight polysom nography studies w ill identify parasym pa- thetic re-innervation in this group. The m ajority of patients w ith transplant associated coronary artery disease do not get chest pain. Presenting features include progressive dyspnoea w ith exertion or the signs and sym ptom s of cardiac failure. Cardiac auscultation m ay reveal a third or fourth heart sound or features of heart failure. Transthoracic 2D echocardiography m ay reveal evidence of poor biventricular function. M ost units do not advocate routine annual coronary angiography for asym ptom atic patients, since the angio- graphic findings do not usually alter clinical m anagm ent. Furtherm ore, conventional coronary angiography does not alw ays confirm the diagnosis; intravascular ultrasound m ay be m ore sensitive. The condition is frequently diffuse and distal and not usually am enable to intervention, e. In those patients w ho have a localised lesion, the disease m ay progress despite successful intervention. The m ajority of centres do not usually offer cardiac re-transplan- tation on account of shortage of donor organs and poor results attendant on cardiac re-transplantation. Absence of bradycardic response to apnoea and hypoxia in cardiac transplant recipients w ith obstructive sleep apnoea. Suzanna Hardman and Martin Cowie The natural history of patients w ith paroxysm al atrial fibrillation is that over a period of tim e (and often m any years) there is a gradual tendency to an increased frequency and duration of attacks. Not all patients require antiarrhythm ic drugs and the potential side effects and inconvenience of regular m edication m ust be balanced against the frequency of episodes and sym ptom atology w hich vary m arkedly betw een patients. Triggers include alcohol and caffeine, ischaem ia, untreated hypertension (w hich if aggressively m anaged can at least in the short term obviate the need for antiarrhythm ics), thyrotoxicosis, and in a sm all proportion of patients vagal or sym pathetic stim u- lation w here attacks are typically preceded by a drop in heart rate or exercise respectively. The m ost effective drugs are also those w ith potentially dangerous side effects. The risks of class 1 agents (such as flecainide, disopyram ide and propafenone) in patients w ith underlying coronary artery disease are w ell recognised and are best avoided. In younger patients (w here it is presum ed the associated risks are proportionately less) they can be highly effective.

Previous chapters have discussed the category of inferential statistics called parametric procedures. Nonparametric procedures are still inferential statistics for deciding whether the differ- ences between samples accurately represent differences in the populations, so the logic here is the same as in past procedures. In this chapter, we will discuss (1) two common procedures used with nominal scores called the one-way and two-way chi square and (2) review several less common procedures used with ordinal scores. Previous parametric procedures have required that dependent scores reflect an interval or ratio scale, that the scores are normally distributed, and that the population variances are homogeneous. It is better to design a study that allows you to use parametric proce- dures because they are more powerful than nonparametric procedures. However, some- times researchers don’t obtain data that fit parametric procedures. Some dependent variables are nominal variables (for example, whether someone is male or female). Sometimes we can measure a dependent variable only by assigning ordinal scores (for example, judging this participant as showing the most of the variable, this one second- most, and so on). But if the data severely violate the rules, then the result is to increase the probability of a Type I error so that it is much larger than the alpha level we think we have. Therefore, when data do not fit a parametric procedure, we turn to nonparametric statistics. They do not assume a normal distribution or homogeneous variance, and the scores may be nominal or ordinal. By using these procedures, we keep the probability of a Type I error equal to the alpha level that we’ve selected. Therefore, it is important to know about nonparametric procedures because you may use them in your own research, and you will definitely encounter them when reading the research of others. With nominal variables, we do not measure an amount, but rather we categorize participants. Thus, we have nominal variables when counting how many individuals answer yes, no, or maybe to a question; how many claim to vote Republican, Democra- tic, or Socialist; how many say that they were or were not abused as children; and so on. In each case, we count the number, or frequency, of participants in each category. For example, we might find that out of 100 people, 40 say yes to a question and 60 say no. These numbers indicate how the frequencies are distributed across the categories of yes/no. As usual, we want to draw inferences about the population: Can we infer that if we asked the entire popu- lation this question, 40% would say yes and 60% would say no? To make inferences about the frequencies in the population, we perform chi square (pronounced “kigh square”). The chi square procedure is the nonparametric inferential procedure for testing whether the frequen- cies in each category in sample data represent specified frequencies in the population. Theoretically, there is no limit to the number of categories—levels—you may have in a variable and no limit to the number of variables you may have. Here we examine the relationship between the different categories and the frequency with which participants One-Way Chi Square 353 fall into each. We ask, “As the categories change, do the frequencies in the categories also change? Being right-handed or left-handed is related to brain organiza- tion, and many of history’s great geniuses were left-handed.

A review of infection control is essential in order to effectively apply isolation principles in the event of a bioterrorist attack. Standard precautions include hand hygiene, safe injection practices and handling of sharps, personal barrier precautions and supplies, and addressing the risk of contamination of the patient environment. Newer elements such as respiratory hygiene/cough etiquette, safe injection practices, and the use of masks for inserting catheters or procedures involving a lumbar puncture have been added (13). These precautions are always applied together with standard precautions, and may be used in combination with one another. Single rooms are always preferred, but where cohorting is the only option, there must be greater than 3 ft distance between beds (13). Droplet precautions do not require rooms with special air handling or ventilation. In addition to other protective garments, all those entering the room must wear a mask. Airborne precautions are required for infectious agents that are a threat over long distances (i. It is mandatory to implement a respiratory protection program that includes the use of respirators, fit testing, and user seal checks. Where this cannot be accomplished, an N95 or higher-level respirator must be worn (13). As identification of the pathogen may take one or more days, decisions must be made based upon clinical presentation (syndromic application—see Table 4) (13,16). Table 5 lists the recommended isolation precautions for each of the organisms by class (13,16–22).
