Teaching materials on the Internet can be used for both education and on-the- job training in nuclear medicine discount suhagra uk erectile dysfunction treatment bangladesh. Staff members can tailor these materials and design their own purpose made teaching packages order generic suhagra line impotence 17 year old male. This is particularly useful when there is no Internet connection available or telephone links are too slow for image file transfer cheap suhagra 100 mg online erectile dysfunction drugs and glaucoma. Advances in telecommunications have opened a new horizon for the promotion of nuclear medicine around the world. Telenuclear medicine will continue to develop quickly once some of the problems, such as the issue of licensing, standards, reimbursement, patient confidentiality, telecommuni- cation infrastructure and costs, have been solved. Ultimately, its cost effec- tiveness and far reaching impact will make telenuclear medicine an extremely useful tool, particularly for developing countries. After careful consideration of the local infrastructure, robustness and cost of nuclear and non-nuclear assays, it is likely that bulk reagent methodology will still be the main workhorse of routine diagnostic services. Quality control will remain a key ongoing continuous activity to assure the quality of results. It is well suited to nationwide targeted screening of congenital diseases and other disorders. In more developed countries, the establishment of indigenous immuno- diagnostics will become one of the essential components of a comprehensive biotechnological strategic plan. It will also be used to set up the first workable immunoassay methodology for new analytes before they are thoroughly evaluated and marketed or transformed into other commercial assay formats. Being a reliable methodology, it is an ideal tool for the development of consensus investigative protocols in evidence based diagnostic medicine. In the near future, the exact role of thousands of genes will be charac- terized by the human genome project. Other bacterial, protozoan, helminthic, viral and fungal genomes have already been, or will be, elucidated very soon. The most important application of this variety of sequences will be in diagnostics. Current diagnostic methods can be slow and relatively insensitive, lack specificity, require invasive clinical samples and, moreover, fail to provide quantitative information about the disease. Molecular methods, based on published sequences, will overcome these constraints to a significant extent. Other applications of molecular methods will be as prognostic markers for cancer, drug resistance indicators, predictive markers for malignant and degen- erative disorders, models for molecular modelling for drug design, gene therapy, pathogenicity evaluation, detection of minimal residual disease, molecular epidemiological information and control measures, and the detection of new emerging diseases. Future development of gamma camera systems dedicated to magnification scintigraphy will open new opportunities in nuclear medicine imaging. New semiconductor detectors are being developed that allow for the manufacturing of specially dedicated cameras with versatile detector sizes and shapes, exhibiting outstanding sensitivity and resolution never achieved before by a nuclear medicine instrument. These new detectors will also be more portable and will permit bedside examinations, as well as coupling with other non-nuclear devices such as mammographs to obtain high resolution functional imaging with full co-registration to facilitate comparison with structural data and improve interpretation. These algorithms yield more accurate trans-sectional data, improving tomographic resolution and avoiding some common image artefacts. Clinical applications The use of sentinel node scintigraphy and other intraoperative applica- tions of probes will increase in their clinical application to a more compre- hensive approach to surgical oncology and other non-oncological indications. Imaging probes are also being developed with the use of semiconductor technology, which will aid in intraoperative localization of the target organ or tissue. Procedure reimbursement will extend to other applications as evidence accumulates in favour of its utilization. Nuclear imaging will become a reference procedure for absolute measurement of physiological and pathophysiological processes for both clinical and research purposes. Receptor tracers are being developed that allow for quantitative and qualitative evaluation of organ functions. Cardiac receptor imaging will be used for more accurate prognosis and management of heart diseases, while other receptor techniques will be employed in oncology for tumour detection and characterization, as well as for selection of the most appropriate therapeutic approach. Nuclear cardiac testing will consolidate as the non-invasive gold standard procedure for ischaemic heart disease. Furthermore, its applications may expand in view of the possible use of electron beam computed tomography as a screening procedure for the detection of coronary artery calcifications in high risk patients. These agents will be used in conjunction with tracer doses to evaluate the progress of the treatment, and will constitute a method complementary to other conventional procedures or even become the treatment of choice for some malignant and non-malignant diseases. The radiobiological basis of low dose, long lived radionuclide therapy will be investigated and will probably lead to new therapeutic strategies. These will in turn lead to accreditation procedures not only for the continuing competence of staff but also for the quality of the facilities and the documen- tation of patient protocols and procedures. With evolving and more complex techniques available, the challenge is evident for all members of the nuclear medicine team, from physicians to technologists and from physicists to radio- pharmacists. Hence, more intensive and extensive training and better continuing education programmes and activities are needed if reliable results are to be obtained and a sustainable growth of the specialty is to be achieved. That means that nuclear medicine specialists and scientists have to work harder to spread the large amount of information available that favours the use of nuclear techniques for a vast range of clinical applications. Evidence based medicine practice is already becoming standard worldwide, so both individual practitioners and institutions will increasingly include nuclear medicine procedures in their diagnostic and treatment algorithms. Emphasis must be placed, however, on cost effectiveness in order to abolish the argument that procedures are too expensive and to demonstrate the innocuousness of the low dose radiation used in most procedures. Often, junior doctors and medical students receive insufficient training in this area of medicine. There are important differences in the management of critically ill patients when compared with relatively stable patients, and these differences are vital in saving lives. Critical care medicine is different from most other disciplines in that the approach is more problem oriented, rather than disease or condition oriented. On the contrary, a clear understanding of the basis of the clinical manifestations in critically ill patients is essential to proper management. Anticipation and forward planning in care is also vital, as is the rapidity of response required from the treating team. While we are often familiar with diseases and conditions, we often feel challenged when faced with having to manage a critically ill patient. This book aims to give junior doctors and medical students an introduction to the practice of critical care medicine, orienting the reader towards a problem- solving approach. It is hoped that this book will serve to make the subject of critical care medicine seem less threatening. I gratefully acknowledge the assistance from Dr Dinoo Kirthinanda and Dr Sujani Wijeratne, Research Associates, who helped with some of the chapters. Special thanks also go to Dr Dinushi Weerasinghe who meticulously formatted and proofread the final draft.

A case against medical care can be m ade knowing what we know today, but an examination o f selected trends in society—a set of possi ble “social futures”—reveals a widening divergence between what medical care can do and the needs of the public 25 years from now. These theses lead to a third: We m ust start over in our efforts to achieve health. This will require new thinking and new approaches, and it will also require abandoning much of the system that now provides medical care. But we must also be revolutionary because the re sources that will be needed to try new approaches are cur rently harnessed to a sophisticated, professionalized medical care system which, in the interests of aiding the few, sacrifices the health of the many. W ithin the next few years, Congress will enact a program o f national health insurance. This legislation will underwrite the costs of care for all citizens of the United States. But if it can be shown, for example, that spending a dollar on educa The Arguments 3 tion would improve health m ore than spending the same dollar on health services, or if it could be dem onstrated that diet and nutrition are far m ore im portant to health than any am ount o f curative care, the need for a national health insurance program becomes doubtful. The issues should be o f vital interest to those interested in fiscal austerity and lean governm ent, as well as to those who feel that health is o f the greatest national im portance, irrespec tive of cost. Should we indenture our health in the future to the existing medical care system when better health might be ensured through other means? T he answer should be no; but it is virtually certain that Congress will do so, and with the support of the vast majority of the people. It calls for the dissolution of the largest and most expensive social service system in the world—the medical care system in the United States. The “radical” critique centers first on the exploitation of the hapless consum er by the rapacious provider and, second, on the failure of the “system” to extend services to everyone, in spite o f the alleged exploitation. This analysis is accurate as far as it goes, but it fails to engage the pivotal issue—what does medicine have to do with health? T he radical solution—the provision o f care to everyone— may simply result in m ore care for those who may not need it. But if it is health we care about, and not medical care, we m ust look for im provem ents in the life setting of the unhealthy, not simply the provision of services designed to cure them once they are sick. If this can be done, then a leaner and tougher approach to health can be created out of the remains of the current delivery system. T he new approach will build on 4 Introduction those things that generate health; unlike present-day medicine, it will not rely on profound interventions when health has been lost. T he United States is about to enter into a “contract” with the exisdng medical care deliv ery system by legislating its legitimacy through a national health insurance program. I begin with evidence on the relative impact of personal m edi cal care and a set of socioenvironmental factors. It is here, in C hapter 2, that m uch of the research and literature on the “effectiveness” of medical care is compiled. T hen I turn to a history o f the “crisis” in health care, together with a discus sion o f its evolutionary features, to show where and how it is evolving. Next I turn to some “social futures” for the United States and their implications for health. This is done dialec- tically, by contrasting the evolution of medicine with a pro jection of the future, to dem onstrate the divergence between the medical care system and the larger society of which it is a part. T he end of medicine is coming both because of inter nal contradictions within the present system and because the system does not correspond with an em erging Zeitgeist. In C hapter 6, I attem pt to state what health is, having spent five chap ters spelling out what it is not.
The following symptoms and conditions often occur in combination: —Reflux oesophagitis; —Hiatus hernia; —Oropharyngeal dysfunction; —Primary and secondary achalasia; —Diffuse oesophageal spasm; —Oesophageal atresia and stricture; —Connective tissue disorders; —Other systemic order 100 mg suhagra mastercard erectile dysfunction psychological causes, neurological and myopathic disorders cheap suhagra 100 mg visa impotence means. In order to evaluate the dynamics of oesophageal transit cheap suhagra on line erectile dysfunction 9 code, dynamic studies using an image matrix of 64 ¥ 64 pixels are required. Patients are usually studied in a fasting state: —Infants under 6 months are kept fasting for 3 hours. For infants, an empty bottle (for administering the radioactivity) as well as a bottle containing the next feed should be brought to the nuclear medicine department. Procedure For the study of deglutition the patient is usually in the supine or an erect position. Data acquisition is usually done in the anterior projection, with frame rates of 298 5. In infants, the rest of the feed is administered after completion of the deglutition study. Visual assessment of oesophageal transit is usually done before quanti- tative analysis is performed. A cine-display of the images is helpful to identify subtle retrograde motion or retention of the tracer. A useful additional method of display is to condense each dynamic image into a single column of pixels (y axis), with time expressed on the x axis. The resulting image of composite vertical lines is often useful to recognize subtle abnormalities. Interpretation The steps listed below should be taken: —Note the activity, positioning and time frames used for the study. Principle Thyroid scintigraphy is based on iodide physiology involving the following: iodine ingestion, trapping and concentration in the thyroid, oxidation and organification to produce iodotyrosines, and a coupling process to form thyroid hormones. In thyroid imaging, the radioiodine is readily taken up by the thyroid gland, where it is trapped and concentrated from the plasma, and then undergoes the organification process. The presence of high concentrations of these radiotracers in the thyroid gland provides excellent visualization of the gland by the gamma camera. Clinical indications Thyroid scintigraphy may be required for any of the following purposes: (a) To determine the size of the thyroid gland; (b) For localization of thyroid nodules; (c) To determine the activity of thyroid nodules; (d) To determine functional status of the thyroid gland; (e) To evaluate presence of ectopic thyroid tissues, thyroglossal duct cysts and substernal masses. Radiopharmaceuticals Details of the radiopharmaceuticals used in thyroid scintigraphy are given in Tables 5. Some centres have tried using other radiopharmaceuticals for evaluation of the thyroid gland. Consequently, doses which are already 24 hours old cannot be used Tc-99m Less expensive and readily Oesophageal activity can be mistaken pertechnetate available for ectopic thyroid tissue More rapid examination Organification function cannot be Provides lowest radiation dose/ evaluated unit of administered activity thyroid replacement treatment cannot be discontinued and for looking for cancer metastases in patients with high serum thyroglobulin but with negative 99m radioiodine scans. Other myocardial perfusion agents ( Tc-sestamibi and tetrofosmin) have also been utilized primarily to search for residual or recurrent thyroid cancer, but their clinical usefulness has not yet been fully 131 assessed. Technetium-99m pertechnetate or low-dose radioiodine I should be used for routine thyroid scanning. Equipment A gamma camera with a pinhole collimator is preferred, to allow multiple views of the thyroid and better resolution of thyroid nodules. Clinical contraindications Radiopharmaceuticals are contraindicated in pregnant women. Enquiries should be made about the menstrual history of female patients in the repro- ductive age group. Discontinuation of breast feeding for nursing mothers (12 hours for 99mTc, permanently for current child with 131I). Procedure The following procedure should be adopted: (a) Patient position: Supine with neck extended to elevate the thyroid. Delayed images at 24 hours have lower body background but with a lower count rate. Note the size, shape and location of the thyroid gland: the thyroid is normally a bilobed or a butterfly shaped organ with each lobe typically measuring 4–5 cm by 1. The thyroid lies superior to the suprasternal notch, though this is dependent on the degree of neck extension present at the time of imaging. Assess the tracer distribution in the thyroid gland: the tracer uptake in the gland should be homogeneous and uniform. Intensely increased uptake in the gland denotes a diffusely hyperplastic gland (e. Uptake in only one portion or one lobe is commonly seen post-surgery or in hyperfunctioning autonomous adenomas. Diffusely decreased tracer uptake or non-visualization may be seen in cases with concomitant anti-thyroid medication, in patients with an increased iodine pool and in patients under thyroid suppression secondary to thyroid replacement therapy. In early subacute thyroiditis (de Quervain’s syndrome), there is very poor tracer localization in the thyroid gland rendering visualization of the gland poor. Correlate with the clinical findings on palpation: evaluation of the nodules is one of the most frequent clinical indications of thyroid scanning. Identification of these nodules is based on areas of altered uptake in comparison with the rest of the gland and should always be interpreted in correlation with the palpation findings. The presence of increased uptake denotes a metabolically active nodule (‘hot nodule’), most often a result of a benign process (autonomous adenoma) as may be seen in Plummer’s disease. However, functioning nodules are not very common, occurring in less than 10% of all demonstrable palpable nodules. In comparison, the presence of nodules with decreased to absent tracer uptake connotes a non-functioning nodule (‘cold nodule’). Solitary cold nodules are commonly due to an adenoma, colloid cyst or primary thyroid carcinoma. Clinical indications Thyroid uptake measurements can be made for the following reasons: (a) To determine the functional status of the thyroid gland; (b) To calculate specific doses for the treatment of hyperthyroidism and ablation therapy of thyroid cancer; (c) To differentiate forms of thyrotoxicosis (thyroiditis, factitious hyperthy- roidism and Graves’ disease). Choose the dose that is closest in activity to the standard for that batch of in-house prepared doses. After oral administration of radioiodine, the 2, 24 and 48 hour uptake measurements are done to see the rate of uptake, total buildup and discharge of radioiodine by the thyroid gland. S1- S2 —Repeat the counting at 24 and 48 hours, and calculate the percentage uptakes. This is normally determined by the dietary iodine intake, types of equipment, standard applica- tions and uptake phantoms. Hyperthyroid individuals (with Graves’ disease, toxic adenoma or toxic multinodular goitre) have elevated uptake values, while patients with subacute thyroiditis or factitious hyperthyroidism will have low to normal uptake values. A low uptake value has a lower precision, brought about by decreased counting statistics. The interpretation of uptake should be made in conjunction with the patient’s history and drug medication intake. Principle Whole body scanning is primarily used for detection of thyroid metastases or thyroid tissue with residual function. Radioiodine is extracted by the residual thyroid tissue and by 75% of well differentiated thyroid cancers with similar iodide physiology.

Chapter 9 • Rehabilitation and Re-education (Movement) Approaches 339 that of radial contraction. Radial contraction is also known Willard (1996a–c) explains that once a sensitization as a precursor to movement in the human organism, has occurred at a spinal segment, that facilitation can such as the transversus abdominis feed-forward be maintained by just a very mild afferent input to the mechanism (Richardson et al 1999).

At this point, even if the therapist were able tion was bidirectional and therefore would have com- to ‘magic’ the tissue trauma away, the patient would promised attempts at forward movement. Equally, contraction clearly requires a nervous system to if that patient were to start to feel better and so use orchestrate it, leading to the advent of chordates. To Hence, the focus should not be on the symptomology, prevent the body from telescoping in on itself, a rigid but on a return to function. This takes the focus away from the dimensions is not optimally controlled across the 4th symptomology and concentrates it on the etiology dimension of time. This is clearly in line with ance or dysfunction in any of the three movement naturopathic principles as outlined in Chapter 1. While this approach may be time- effective and is not un-useful, it does mean that pre- Muscle imbalance physiology scription of treatment – corrective stretching, corrective mobilization, corrective exercises and other nutrition Muscle imbalance physiology was ﬁrst described by and lifestyle advice – may be somewhat non-speciﬁc.

Nevertheless, this pain patients, it is critical to provide a focus on return- author considers identiﬁcation and correction of ing function as opposed to getting rid of dysfunction. This means that a patient can make great strides Perhaps one reason for the decline in interest in towards a return of function, yet may still have a muscle imbalance is that, as with nearly all clinical similar symptom proﬁle. This phenomenon may be entities, to ﬁnd a ‘textbook’ case is less common than explained neurophysiologically through the process ﬁnding a partial case.

Hence, it is entirely possible that Lengthen/weaken Shorten/tighten a patient may attend with a muscle imbalance (which represents a biomechanical dysfunction) yet have no pain. Nevertheless, any muscle imbalance disrupts the optimal axis of joint motion (a spatial or three- we may be able to see improvement – even though dimensional dysfunction) which will, over time, result the patient may be able to feel little difference. The fore, the means to assess joint position, joint range of point at which the sufferer feels pain is the point at motion and length–tension relationships objectively is which the rate of damage exceeds the rate of repair critical, in order to manage patients effectively and (see Fig. Interestingly, even among these experts, there load it is useful to have, at the very least, a Swiss ball, was still some confusion regarding muscle classiﬁca- but ideally a cable column and a squat rack with tion.

It is not uncommon to hear that a those over 65 years of age (Chek 2004b); hence a therapist works with a mainly elderly population, naturopathic approach is surely to prevent such falls.

Therefore, Swiss be able to walk (one base of support for 80% of the ball conditioning is ideal for training fall prevention in the gait cycle).

Both nitroglycerin and nitroprusside produce vasodilatation in the capacitance vessels thus improving cardiac hemodynamics buy generic suhagra 100 mg line erectile dysfunction treatment homeveda. Nitroprusside has a more pronounced effect on arterioles 100 mg suhagra mastercard impotence guilt, thus reducing afterload order 100mg suhagra free shipping erectile dysfunction pills non prescription. However, a reflexive tachycardia and increased inotropy may counteract the decrease in afterload and even lead to an increase in cardiac workload. Nitroprusside may also cause coronary steal in patients with coronary artery disease. It is therefore not the first line drug in cardiac failure with severe hypertension. Cardiovascular Disorders 19 Aortic Dissection • The control of hypertension is essential in the emergency stabilization of a patient with an aortic dissection. Hypertension and Acute Renal Failure • Patients with long-standing uncontrolled hypertension often develop renal failure. Acute elevations in blood pressure may lead to intrarenal vascular injury, glomerular ischemia, and subsequent hematuria, proteinuria and loss of renal function. They must be used with caution, and euvolemia must be maintained in order to not decrease renal perfu- sion to a level which exacerbates instead of alleviating renal damage. Nitroprusside, while effective for decreasing blood pressure, is problematic in patients with renal dysfunction because the thiocyanate metabolite of the drug may accumulate, leading to cyanide toxicity. Preeclampsia/Eclampsia • Preeclampsia and eclampsia represent diffuse end-organ damage secondary to preg- nancy induced hypertension. The treatment for preeclampsia/eclampsia is delivery of the fetus and pla- centa and close communication with an obstetric specialist is required. Microangiopathic Hemolytic Anemia • The endovascular damage associated with hypertensive crises results in fibrin deposi- tion in arterioles and ultimately fibrinoid necrosis. This fibrin deposition may lead to a hemolytic anemia which is diagnosed by the presence of schistocytes on peripheral blood smear. This anemia is rarely seen in isolation in hypertensive emergencies and management is based on end-organ damage in other organ systems. Catecholamine Excess • Excess catecholamines may lead to hypertensive emergencies. In the case of stimulant drug ingestions, anxiolytics such as lorazepam or valium may be effective in lowering blood pressure as well as treating associated hyperactivity. Patients must be closely 2 monitored during the use of these medications for adverse reactions including hy- potension or worsening of the underlying condition. Sodium Nitroprusside • Nitroprusside is the drug of choice for most hypertensive emergencies. The half-life is 3-4 min which allows the pharmacologic effect to be quickly discontinued in patients with adverse reac- tions. However, in patients with congestive heart failure, nitroprusside has been shown to be effective in increasing cardiac output. Nitroprusside’s potent vasodilatation may cause dilation in the cerebral vasculature, thus increasing cerebral blood flow and intracerebral swelling. However, the decrease in systemic blood pressure counteracts this effect, making nitroprusside the drug of choice in patients with hypertensive encephalopathy. Nitroglycerin • Nitroglycerin is a direct vasodilator that acts predominantly on the venous circulation. Nitroglycerin decreases preload which improves cardiac mechanics in failing hearts. Therapeutic effect can be seen in approximately 2-5 min and peaks in approximately 10 min. Initial loading dose of 20 mg over 2 min can be repeated in 10 min intervals until a response is noted. It has a favorable effect on failing hearts by improving ejection fraction and acts as an anti-anginal by dilating coronary arteries. Hydralazine • Hydralazine produces direct vasodilatation and is the drug of choice in hypertensive emergencies associated with pregnancy. Nifedipine • Oral nifedipine was used commonly in the treatment of hypertensive emergencies. Unfortunately, this reduction in blood pressure is often uncontrolled, leading to adverse effects on cerebral blood flow as well as adverse cardiac effects secondary to reflexive tachycardia. It is 2 also not easily titratable and thus may be dangerous if adverse effects occur. Common Effects of Anti-Hypertensive Medications Anti-hypertensive medications are prescribed commonly. A functional knowledge of the use and side-effect profile of these drugs is important when managing pa- tients taking these medications. Diuretics • Diuretics are an excellent choice for initial therapy in hypertension. If they are not the initial medication used, they are indicated as a secondary medication as they have an additive effect on blood pressure when used in combination. They are especially useful in patients with ischemic heart disease, tachydysrhythmias, essential tremor, or mi- graines. Calcium Channel Blockers • Calcium channel blockers are especially effective in African Americans. Hyperkalemia may also occur as well as worsening of renal failure especially in patients with renal artery stenosis.

The sixth report of the joint national committee on prevention, detection, evaluation, and treatment of high blood pressure. Part B: Acute Coronary Syndromes Coronary artery disease is the most common cause of death in the United States, accounting for approximately 600,000 deaths annually. It has been estimated that the overall cost of coronary artery disease exceeds 100 billion dollars annually in the U. There is also a significant cost in terms of malpractice claims, with missed myocardial in- farction and acute coronary syndromes continuing to constitute a large percentage of both claims and costs. There was a 54% reduction in age-adjusted mortality from myocardial infarction in the U. However, other sources of occlusion include throm- bus formation associated with arterial dissections as well as thrombi from heart cham- bers and prosthetic valves. Inflammatory processes, such as those associated with 2 Kawasaki disease and systemic lupus erythematosis are uncommon causes of coro- nary artery disease. However, many variations exist including burn- ing pain, pain akin to indigestion (approximately 20% of patients) and sharp, stab- bing pain (5-20% of patients). Pain may radiate to the jaw, neck, back or down either upper extremity, corresponding to the C8-T5 dermatomes. In some of these cases an “anginal equivalent” such as shortness-of -breath, lightheadedness or nausea may be present. The presence of a tall R wave in lead V1 is the equivalent of a Q wave in the other infarct locations. Its presence indicates a poor prognosis and the need for more aggressive management.
