This Guide acknowledges and respects that todays modern healthcare provider may have only a brief window of time for physical activity counseling (at times no more than 20-30 seconds) during a normal office visit effective viagra capsules 100 mg. Refer your patients to certified exercise professionals generic 100mg viagra capsules fast delivery, who specialize in physical activity counseling and will oversee your patients exercise program order cheap viagra capsules line. The Physical Activity Assessment, Prescription and Referral Process documents are the core of the guide and will explain how you can quickly assess physical activity levels, provide exercise prescriptions, and refer patients to certified exercise professionals. Print out and display copies of the Office Flyers in your waiting room and throughout your clinic. Regularly assess and record the physical activity levels of your patients at every clinic visit using the Physical Activity Vital Sign. For patients with chronic health conditions, the Your Prescription for Health series will provide them with more specialized guidance on how to safely exercise with their condition. Once you are comfortable with the prescription process, begin referring your patients to local exercise professionals who will help supervise them as they fill their physical activity prescriptions! These steps are all described in greater detail throughout the rest of this Action Guide. Keep reading to find how you can make a difference in getting your patients to be more physically active! In contrast, physical inactivity accounts for a significant proportion of premature deaths worldwide. As a healthcare professional, you are in a unique position to provide such expertise to your patients and employees in helping them develop healthy lifestyles by actively counseling them on being physically active. The first step you can take within your healthcare setting is to ensure that you walk the talk yourself. Data suggests that the physical activity habits of physicians 1 influence their counselling practices in the clinic. To be a role model for your healthcare team and to gain the trust of your patients, an important first step is setting an example and showing that being physical active is important to you! Next, we encourage you to focus on the well-being of your healthcare team and implement steps that will increase their physical activity levels and healthy lifestyle choices. Some of these steps may include: Implementing wellness challenges and programs Offering physical activity classes (i. Finally, we strongly encourage you to promote physical activity in your clinic setting. You may not always have time to engage your patient in conversations about their physical activity levels, but there are simple steps that you can take to make sure they realize its importance in their personal health. By calling attention to and promoting small, simple things that they can do, it will add up to a much more active, healthier patient. We encourage you to post the flyers in your patient waiting and examination rooms. Copies of the flyers can be left on display on tables for patients to take with them after they have left your office. Together, they will create an immediate, first impression on your patients before they even begin their visit! Physical activity habits of doctors and medical students influence their counselling practices. Your discussion of their current physical activity levels may be the greatest influence on their decision. The assessment of their physical activity levels initiates this discussion, highlights the importance of physical activity for disease prevention and management, and enables your healthcare team to monitor changes over subsequent medical visits. While there are multiple advanced and comprehensive physical activity assessments tools available, time constraints often necessitate a simple and rapid tool. The Physical Activity Vital Sign: A Primary Care Tool to Guide Counseling for Obesity. Exercise as a Vital Sign: A Quasi-Experimental Analysis of a Health System Intervention to Collect Patient-Report Exercise Levels. Providing your patient with a physical activity prescription is the next key step you can take in helping your patients become more active. Your encouragement and guidance may be the greatest influence on this decision as patient behavior can be positively influenced by physician intervention. The steps provided below will give you guidance in assessing your patients and their needs in becoming more active. At this point, youve already determined their current physical activity level (the Physical Activity Vital Sign). Next, you will determine if your patient is healthy enough for independent physical activity. Finally, you will be provided with an introduction to the Exercise Stages of Change model to help determine which strategies will best help your patient become physically active. Step 1 - Safety Screening Before engaging a patient in a conversation about a physical activity regimen, it is necessary to determine if they are healthy enough to exercise independently. However, it may be necessary to utilize more advanced screening tools such as the American College of Sports Medicine Risk Stratification (see Appendices D & E) or a treadmill stress test to determine whether your patient should be cleared to exercise independently or whether they need to exercise under the supervision of a clinical exercise professional. Individuals attempting to change their behaviors often go through a series of stages. Some patients may only be ready for encouragement, some will be prepared to take steps towards being more physically active, while others will be ready to receive a physical activity prescription and referral to certified exercise professionals. Therefore, prior to prescribing physical activity to your patients, it is important to determine their Stage of Change. By determining the stage of change that they are in, you can then take the most appropriate action based and individualize your physical activity promotion strategy. The Exercise Stages of Change questionnaire (found in Appendix F) consists of 5 questions and can be completed in a matter of minutes when your patient first checks in at your office. The following table provides a brief outline of each of the five stages of change and recommended steps for patients in each stage. Stage of Change Action Step Promote being more physically active by discussing its health benefits, Precontemplation emphasizing the pros of changing their behavior, and helping work (Patient has no intention to be physically through the cons of being more physically active. Independent Supervision Necessary Write prescription; refer to Refer to clinical exercise exercise professional. Contemplation (Patient is thinking about becoming Continue to emphasize the pros and reducing the cons of being more physically active) physically active. Preparation Write prescription; refer to non- Refer to clinical exercise (Patient is active and making small clinical exercise professionals. The simplest prescription that you can provide your patient with is to participate in 150 minutes of moderate intensity physical activity each week as suggested in the 2008 5 Physical Activity Guidelines for Americans. Studies have shown that simply providing a written prescription is an effective means of motivating patients to be more physically active, sometimes by as 6 much as one hour per week. The Exercise Prescription Health Series consists of 45 customized exercise prescriptions specifically developed for individuals with a variety of health conditions such as diabetes, cardiovascular disease, osteoarthritis, and lower back pain.
These developments have led to the birth of a new economic sec- tor order generic viagra capsules canada, the biotech industry viagra capsules 100 mg cheap, associated mostly with small start-up companies viagra capsules 100 mg on line. For their part, the more established healthcare com- panies have also been employing these modern techniques, known collectively as biotechnology, successfully for many years. By studying the molecular foundations of diseases they have developed more specific ways of combating diseases than ever before. This new knowledge permits novel approaches to treatment, with new classes of drug biopharmaceuticals at- tacking previously unknown targets. Increasing attention is also being paid to differences between individual patients, with the result that in the case of many diseases the goal of knowing in advance whether and how a particular treatment will work in a given patient is now within reach. When a disease, rather than being diagnosed on the ba- sis of more or less vague signs and symptoms, can be detected on the basis of molecular information, the possibility of suc- cessful treatment depends largely on what diagnostic techniques are available. To the healthcare industry this represents a major development in that diagnosis and treatment are growing ever closer together, with clear benefits for companies that possess competence in both these areas. To patients, progress in medical biotechnology means one thing above all: more specific, safer and more successful treatment of their illnesses. For example,more than 40% of the sales of Roches ten best-sell- ing pharmaceutical products are currently accounted for by bio- pharmaceuticals, and this figure is rising. This booklet is intended to show what has already been achieved via close cooperation between basic biological research, applied science and biotechnologically based pharmaceutical and diag- nostic development. Just as in the past the development of beer, bread and cheese were major breakthroughs, another revolution is now about to overtake medicine: compounds produced using biotechnological methods are opening up entirely new possibilities in medical diagnostics and therapy, and in so doing are bringing about a major restructuring of markets. From knowledge to science: the history of biotechnology Babylonian biotechnologists were a highly regarded lot. Their products were in demand among kings and slaves and were ex- ported as far as Egypt. They are even mentioned in the Epic of Gilgamesh, the worlds oldest literary work the Babylonian brewers, with their 20 different types of beer. Their knowledge was based on a biological technology that was already thousands of years old fermentation Terms by yeast. Biopharmaceuticals drugs manufactured using biotech- Though it may sound nological methods. The only thing that is relatively new about the biotechnology industry is its name. Stone Age, Iron Age, The term biotechnology was first used in a 1919 Age of Biochemistry publication by Karl Ereky, a Hungarian engineer and economist. He foresaw an age of biochemis- try that would be comparable to the Stone Age and the Iron Age in terms of its historical significance. For him, science was part of an all-embracing economic theory: in combination with po- litical measures such as land reform, the new techniques would provide adequate food for the rapidly growing world population an approach that is just as relevant today as it was in the pe- riod after the First World War. Until well into the second half of the 20th century biologists worked in essentially the same way as their Babylo- Beer for Babylon 9 1665 C. Two years later Antoni van Leeuwenhoek becomes the first person to see bacterial cells. Thanks to newly developed methods, however, the biotechnol- ogy of the 20th century was able to produce a far greater range of such natural products and at far higher levels of purity and quality. This was due to a series of discoveries that permit- ted the increasingly rapid development of new scientific tech- niques: T In the first half of the 19th century scientists discovered the basic chemical properties of proteins and isolated the first enzymes. Over the following decades the role of these sub- stances as biological catalysts was elucidated and exploited for research and development. T The development of ever more sophisticated microscopes rendered the form and contents of cells visible and showed the importance of cells as the smallest units of life on Earth. Louis Pasteur postulated the existence of microorganisms and believed them to be responsible for most of the fermen- tation processes that had been known for thousands of years. T From 1859 Charles Darwins theory of evolution revolution- ised biology and set in train a social movement that led ul- timately to a new perception of mankind. For the first time the common features of and differences between the Earths organisms could be explained in biological terms. As a result, biology changed from a descriptive to a more experimental scientific discipline. T The rediscovery of the works of Gregor Mendel at the end of the 19th century ushered in the age of classical genetics. Cultivation and breeding techniques that had been used for thousands of years now had a scien- tific foundation and could be further developed. It will be white blood cells in purulent 35 years before his work receives the bandages that he refers to as nuclein. In addition to the classical, mostly agricultural, products, more and more new products entered the market- place. Enzymes were isolated in highly purified form and made available for a wide variety of tasks, from producing washing powder to measuring blood glucose. Standardised biochemical test methods made their entrance into medical diagnostics and for the first time provided physicians with molecular measuring instruments. The structures and actions of many biomolecules were elucidated and the biochemical foundations of life thereby made more transparent. Gene technology spurs However,it was only with the advent of gene tech- innovation nology that biology and biotechnology really took off. Desired changes in the genetic makeup of a species that previously would have required decades of system- atic breeding and selection could now be induced within a few months. For example, newly developed techniques made it possible to in- sert foreign genes into an organism. This opened up the revolu- tionary possibility of industrial-scale production of medically important biomolecules of whatever origin from bacterial cells. The first medicine to be produced in this way was the hormone insulin: in the late 1970s Genentech, an American company, de- veloped a technique for producing human insulin in bacterial cells and licensed the technique to the pharmaceutical company Eli Lilly. Gene technology: human insulin from bacteria In 1982 human insulin became the worlds first biotechnolog- In 1978 the biotech company Genentech developed a method ically manufactured medicine. These were then separately isolated, combined and betes and most people with type 2 diabetes require regular finally converted enzymatically into active insulin. In its day, this classical biotechnological method it- Some 200 million diabetics worldwide now benefit from the self represented a major medical breakthrough: until 1922, production of human insulin. Without gene technology and when medical scientists discovered the effect of pancreatic biotechnology this would be impossible: in order to meet cur- extracts, a diagnosis of type 1 diabetes was tantamount to a rent demands using pancreatic extract, around 20 billion pigs death sentence. A new economic This technology laid the foundation for a new in- sector arises dustry. The early start-up biotech companies joined forces with large, established pharmaceu- tical companies; these in turn used biotechnology to develop high-molecular-weight medicines. Rapid expansion In the early 1980s very few companies recognised and stock market boom the medical potential of the rapidly expanding field of biotechnology.
A serum prolactin level greater than 300ng/ml strongly suggests the presence of prolactinoma purchase genuine viagra capsules on line. Surgical therapy: transsphenoidal surgery: cures most patients with small adenomas viagra capsules 100 mg low cost. Medical: Bromocriptine is remarkably effective in decreasing prolactin level order viagra capsules with american express, usually, to normal. It may be used in conjunction with surgery and bromocriptine to further reduce tumor size and function. Primary/Idiopathic: account for approximately 50 % of the cases of diabetes insipidus. Injury to the hypothalamus pituitary area: may result from head trauma, neurosurgical procedures such as hypophysectomy. Nocturia is almost always present, which may disturb sleep and cause mild day time fatigue or somnolence. A conscious patient with normal thirst mechanism and free access to water will maintain hydration. However rapid and life threatening dehydration and hypovolemia may develop rapidly, if urinary losses are not continuously replaced, which may occur in unconscious patients or infants. Measurement of plasma osmolality: in untreated patients helps to distinguish the cause of polyuria. In psychogenic polydipsia excess fluid intake is primary and serum osmolality is low (255 - 280 mOsm/kg ) 488 Internal Medicine 2. Water deprivation test: started in the morning by weighing the patient, obtaining venous blood to determine electrolyte concentrations and osmolality, and measuring urinary osmolality. Fluid intake is withheld, and voided urine is collected hourly and its osmolality is measured. Dehydration is continued until Orthostatic hypotension and postural tachycardia appear, 5% or more of the initial body weight has been lost, or The urinary concentration does not increase by more than 30 mOsm/L in sequentially voided specimens for 3 hrs. Severe disabling headache is reported to occur at least annually by 40% of individuals worldwide. Vascular headache Migraine headache Cluster headache Miscellaneous (orgasmic, Hangover) 2. Extra cranial lesions Paranasal sinusitis Dental problems Ear problems Ocular problems Cervical problem Evaluation of patients presenting with Headache When evaluating a patient with headache, the goal is to: Distinguish serious headache from benign headache syndrome Give appropriate treatment. It should include Vital signs (Blood pressure, temperature) Head and neck examination: scalp tenderness, sinus tenderness, examination of the oral cavity and tempromandibular joint. After appropriate evaluation of the headache the following clinical features should be considered as indicators of serious underlying disease. First severe headache ever described as the worst type of headache in the patients life may suggest subarachnoid hemorrhage 492 Internal Medicine 2. Vascular headache Vascular headaches refers to a group of headache syndromes, of unknown cause,in which pain results from dilation of one or more of branches of carotid arteries. A) Migraine Headache Definition: migraine headache is a benign and episodic disease, characterized by headache, nausea, vomiting and/ or other symptoms of neurological dysfunction. Etiology: the cause of migraine is often unknown, but several common precipitants have been observed. Pathogenesis: different hypothesis are proposed including: 1) Vascular theory: in this theory it is said that migraine and neurological symptoms are results of extracranial vasodilatation and intracranial vasoconstriction. Clinical feature Migraine may be precipitated by some of the factors mentioned above. The syndrome of Classical migraine has five phases: Prodromal phase: characterized by lassitude, irritability difficulty in concentrating Aura phase: patients with aura often report visual complaints, vertigo, aphasia or other neurological deficit before the onset of the headache Headache phase characteristic migraine headache Headache termination usually occurs within 24 hours Post headache phase feeling of fatigue. Sleepiness and irritability Characteristic Migraine head ache is: Moderate to severe head pain, pulsating quality often unilateral ( affecting half part of the head ) It is exacerbation by physical activity and relived by sleeping It is often associated with Nausea and/or vomiting, photophobia, phonophobia/ sonophobia (dislike ad avoidance of laud sounds or noises). There are different variants of Migraine Common migraine This is the commonest variation of migraine headache No focal neurological disturbance precedes the recurrent headache 494 Internal Medicine Classic migraine It is associated with characteristic premonitory sensory, motor or visual symptoms. Most common symptoms reported are visual which include scotomas and/or hallucinations. Complicated migraine Migraine associated with dramatic transient neurological deficit, or a migraine attack that leaves a persisting residual neurological deficit. These drugs are effective for mild to moderate attacks and are most effective when taken early. Nonselective (Ergot preparations: Ergotamine and dihydro-ergotamine) o Widely used for relief of acute attacks o Has oral, sublingual, rectal, nasal and parentral preparation. Excess use may lead to rebound headache and dependency o Contraindication: patients with vascular diseases like coronary heart disease ii. Selective - Triptans including (Naratriptan, Ritatriptan, Sumatriptan, and Zolmitriptan): are new drugs in management of migraine. Prophylactic Treatment: includes drug regimens and changes in patients behavior Medical therapy: These are drugs that have capacity to stabilize migraine. Prophylactic treatment is indicated if the patient has three or more attacks per month. It lessens migraine attacks by helping patients deal more effectively with stress B) Cluster Headache Cluster head ache is a vascular headache syndrome, characterized by severe, acute headache that occurs in clusters lasting several weeks followed by pain free intervals that averages a year. Male: Female ratio is 8:1 rd th Usually begins 3 to 6 decades Cluster headache is periorbital less commonly temporal. It is also severe and explosive in quality lasting 30 min to 2hrs, subsiding abruptly. Etiology: various precipitating factors may cause tension headache in susceptible individual including. Clinical feature Tension headache is characterized by mild or moderate, bilateral pain. If treatment is unsatisfactory addition of caffeine or other analgesic is beneficial. Physical Therapy: different techniques can be used including Hot or cold application Positioning Stretching exercises Traction Massage 3. Psychological Therapy Includes reassurance, Counseling, relaxation, stress management programs and biofeedback techniques reduce both the frequency and severity of chronic headache. D) Headache Associated with Brain Tumor About 30% of patients with brain tumor present with headache. Headache of brain tumor is usually intermittent dull aching, moderate intensity which worsens with time. It disturbs sleep in about 10% of patients, exacerbated by exertion and postural changes. Clinical feature Typical presenting symptom includes headache, polymyalgia rheumatica, jaw claudication, fever and weight loss.
