Long term follow up necessary Treat 72 older adults for 5 years to prevent 1 death purchase disulfiram 500 mg on line, treat 43 for 5 years to prevent one cerebrovascular event Aim of treatment: diastolic < 90 Rules of thumb: Use low doses of several agents generic 500mg disulfiram with amex, rather than increasing doses of one drug (especially thiazides) First line: thiazides (with or without a potassium sparing agent) and/or -blocker (atenolol most used in trials) purchase 500 mg disulfiram amex. Caused by reversible spasm in normal to severely atherosclerotic coronary arteries. Within 3 months 4% will have sudden death and 15% a myocardial infarct Sudden cardiac death. Want to test lipids/cholestrol but false positives following an acute coronary event. Q wave Subendocardial infarct: multifocal necrosis confined to inner 1/3 to of left ventricle wall. Normal value depends on which assay is used I remains elevated for 5 9 days and T for 2 weeks. False positives with heart failure Myoglobin: Oxygen binding protein in skeletal and cardiac muscle. Treatment - steroids) Mural thrombosis embolisation Myocardial rupture tamponade. Echocardiogram is poor at detecting thrombis (trans-oesophageal echocardiogram is better) Management: Cardioversion: indicated if onset is within 24 48 hours and no other risk factors (eg no atrial enlargement or ventricular abnormality). May need anticoagulation for cardioversion (thrombi may get dislodged if normal rhythm returns). T = heart block, worsening of heart failure, 8 hours asthma Antithrombotic therapy: Reduces annual risk in those at risk from 5% to 1. Use aspirin if warfarin contra-indicated (only 10 15% relative risk reduction) Atrial flutter: probably due to atrial re-entry. Management: transvenous or transthoracic pacing, dopamine or adrenaline, pacemaker Drugs for Acute, Life Threatening Arrhythmias For tachycardias: Ventricular Tachycardia: Lignocaine: dose 1 1. Action on sodium channels reduces myocardial excitability, especially in ischaemic myocardium. Use if lignocaine fails Procainamide: powerful antiarrhythmic and strong negative inotropic agent, but slow to act. Preload and afterload reduced Diuretics: frusemide also causes venodilation ( preload) Antihistamines: H1 antagonists (promethazine / Phenergan), H2 antagonists (ranitidine) Emergency cardiac pacing Complete heart block most common indication. Also for non-response bradycardias and asystole with P waves Transcutaneous/transthoracic pacing: Electrodes over apex and sternum. Longer, harsher murmur best heard at the left sternal edge Hard to confuse with mitral regurgitation (!! Copes with tachycardia better than stenosis: proportion of cycle in diastole proportion of blood flowing back into the ventricle. Loudest with bell at apex and left lateral side Pulmonary oedema is worse than in other causes (eg mitral regurgitation) If pulmonary hypertension then low cardiac output failure thin patient, peripheral cyanosis, cool extremities, small pulse volume. Dilatation of the mitral annulus and lateral displacement of the papillary muscles Hypertrophic cardiomyopathy (thickening in parts of wall e. If aortic valve narrowed then faster flow then > 3 m/sec (same amount of blood through smaller space). In elderly, effect of loop diuretics may be delayed through poor absorption, and elimination effect. Neutrophil infiltrate Interstitial myocarditis: Characteristic of viral myocarditis Occurs mainly in children and young women Most have benign, self limiting course Microscopic appearance: oedema, chronic inflammatory cells Parenchymatous myocarditis: diffuse, patchy destruction of muscle cells. But 30% of hypertensives are non-responders Eg Captopril, quinapril Many patients (especially the elderly) dont respond on its own. Effect: mainly vasodilation, also inhibit Na/K co-transport in distal convoluted tubule salt and water loss. Dilate peripheral arterioles (modern ones dont cause reflex tachycardia), less arterial dilation. Bind fat soluble vitamins and other drugs (eg warfarin, give two hours before or 4 hours after) Cardiomyopathy = Primary or idiopathic diseases involving the myocardium. Septum thicker than free wall of left ventricle Microscopic appearance: diffuse hypertrophy of tangled myocytes. Painful purple to brown lesions Myxoma: most common primary benign tumour of the heart. Jelly like appearance, typically located on the atrial side of the mitral valve th th 54 4 and 5 Year Notes Rhabdomyoma: primary benign striated muscle cell tumour of the myocardium, typically found in children Cardiovascular 55 th th 56 4 and 5 Year Notes Respiratory Physiology. If flux falls below 250 then hypoxia Cyanosis: Peripheral cyanosis: capillary de-oxy Hb > 50 g/litre. Maximum responsiveness usually 20 minutes after dosing Predicted values are based on age, height and sex. Different racial groups and people with varying proportions (eg long legs/short torso) may be very poorly approximated by predicted values Flow-volume Loop gives very valuable information. Look for paradoxical breathing of the abdomen Cyanosis (eg tongue) Ask patient to cough. Signs are: Expansion: reduced on affected side Vocal resonance and tactile fremitus (patient says 99 and listen with stethoscope/feel with hand): on affected side Percussion: dull but not stony dull Breath Sounds: increased volume and bronchial not vesicular (ie will hear coarse breath sounds like over the trachea) Additional Sounds: inspiratory crackles (as pneumonia resolves) Vocal Resonance: increased Plural Rub: may be present Effusion = fluid in pleural space (but not blood thats haemothorax, and not pus thats empyema). By back of nose air is 98% humidified and 35 C Anatomy: maxillary, ethmoid, frontal and sphenoid sinuses.

On average, every year national data generated by continuous surveillance systems surveys are carried out in 20 countries worldwide, is progressively increasing, due to the increasing and 20 more are in preparation. In some instances, a single genetic event may be which is transmitted via the bite of female Anopheles all that is required to confer drug resistance; in others, mosquitoes. In the human body, parasites travel in multiple independent events may be necessary before the bloodstream to the liver, where they multiply a resistant strain of the parasite emerges (6). Among the second phase, resistant parasites are selected for and ve species of Plasmodium parasites that infect begin to multiply, eventually resulting in a parasite humans (P. The most dangerous form of malaria, with the who receive inadequate amounts of an antimalarial highest rates of complications and mortality, is caused drug are at high risk for de novo resistance. The spread of resistance is further become life-threatening as the vital organs are driven by the use of drugs which are eliminated deprived of oxygen and nutrients due to disruptions only slowly from the body, such as chloroquine, in the blood supply. Resistance to antimalarial drugs has threatened global malaria control since the emergence of resistance to chloroquine in the 1970s. Similarly, in the There is no simple laboratory test to identify drug 1980s, resistance to meoquine emerged rapidly on resistance in malaria. Cross-resistance can occur to drugs observed; these drugs are now among those used belonging to the same chemical family, or those that as partner drugs in artemisinin-based combination share the same modes of action. During the the evolving picture of antimalarial drug resistance network meetings, held every year or every second in their region and globally. Network meetings provide an important 50 Surveillance of antimicrobial drug resistance in disease-specic programmes / 4. Specically, clearance for studies, conducting clinical monitoring, treatment failures occurred following administration of procuring antimalarial drugs and providing nancial artesunate-meoquine in Cambodia (17) and Thailand support. An important factor in successful monitoring (18), and dihydroartemisinin-piperaquine in Cambodia has been attribution of full credit and ownership of (19).

Adamantane resistance became fxed methods for the detection of resistance or decreased in A(H3N2) viruses after a rapid increase in prevalence susceptibility: genotypic assays and phenotypic assays.
