For example: ‘1 in 1 cheap levothroid 50mcg mastercard thyroid gland food good,000’ means 1g in 1 discount levothroid 100mcg otc thyroid gland hyperplasia,000mL ‘1 in 10,000’ means 1g in 10,000mL Therefore it can be seen that 1 in 10,000 is weaker than 1 in 1,000. The drug most commonly expressed this way is adrenaline/epinephrine: Adrenaline/epinephrine 1 in 1,000 which is equal to 1mg in 1mL Adrenaline/epinephrine 1 in 10,000 which is equal to 1mg in 10mL An easy way to remember the above is to cancel out the three zeros that appear after the comma, i. Adrenaline/epinephrine 1 in 1,000 – cancel out the three zeros after the comma: 1,000/ / /, to give: 1 in 1 which can be written as: 1mg in 1mL Similarly, for adrenaline/epinephrine 1 in 10,000 – cancel out the three zeros after the comma: 10,000/// to give: 1 in 10, which can be written as 1mg in 10mL. Just as per cent means parts of a hundred, so parts per million or ppm means parts of a million. It usually refers to a solid dissolved in a liquid but, as with percentage concentrations, it can also be used for two solids or two liquids mixed together. Once again, by agreed convention: 1 ppm means 1g in 1,000,000mL or 1mg in 1 litre (1,000mL) In terms of percentage, 1 ppm equals 0. Other equivalents include: One part per million is one second in 12 days of your life! Haz-Tabs®) are measured in terms of parts per million, such as 1,000 ppm available chlorine. Question 12 It is recommended that children should have fluoride supplements for their teeth if the fluoride content of drinking water is 0. Such large molecules are difficult to purify and so, rather than use a weight, it is more accurate to use the biological activity of the drug, which is expressed in units. The calculation of doses and their translation into suitable dosage forms are similar to the calculations elsewhere in this chapter. Infusions are usually given over 24 hours and the dose is adjusted according to laboratory results. As a result of this cumulative administration error the patient died from a brain haemorrhage which, in the opinion of the pathologist, was due to the overdose of tinzaparin. It was the prescriber’s intention that the patient should receive 9,000 units of tinzaparin each day, but this information was not written on the prescription. The ward sister told a coroner’s court hearing that the prescription was ambiguous. Insulin Injection devices (‘pens’), which hold the insulin in a cartridge and deliver the required dose, are convenient to use. However, the conventional syringe and needle are still the method of insulin administration preferred by many and are also required for insulin not available in cartridge form. Insulin comes in cartridges or vials containing 100 units/mL, and the doses prescribed are written in units. Therefore, all you have to do is to dial or draw up the required dose using a pen device or an insulin syringe. Insulin syringes are calibrated as 100 units in 1mL and are available as 1mL and 0. So if the dose is 30 units, you simply draw up to the 30 unit mark on the syringe. Displacement Values or Volumes • Dry powder injections need to be reconstituted with a diluent before they are used. Sometimes the final volume of the injection will be greater than the volume of liquid that was added to the powder. They include calculating number of tablets or capsules required, divided doses, simple drug dosages and dosages based on patient parameters, e. It is important that you are able to do these calculations confidently, as mistakes may result in the patient receiving the wrong dose which may lead to serious consequences for the patient. After completing this chapter, should you not only be able to do the calculations, but also be able to decide whether your answer is reasonable or not. However, there may be instances when the strength of the tablets or capsules available do not match the dose prescribed. The answer involves finding how many 25s there are in 75 or in other words 75 divided by 25: 75 3 = =3tablets 25 1 Dosages based on patient parameters 83 In most cases, it is a simple sum you can do in your head, but even so, it is a drug calculation – so care must always be taken. A patient is prescribed 2g of flucloxacillin to be given orally but it is available in 500mg capsules. Once again it is a simple calculation but it is slightly more complicated than our earlier example as the dose prescribed and the available medication are in different units. We could either convert the 500 mg into grams, or we could convert the 2 g into milligrams.
Internationally accepted abbreviations should be used: g for gram levothroid 200 mcg with amex thyroid nodules heart palpitations, ml for milliliter proven levothroid 50mcg thyroid cancer symptoms yahoo. Try to avoid decimals and, where necessary, write words in full to avoid misunderstanding. Badly handwritten prescriptions can lead to mistakes, and it is the legal duty of the doctor to write legibly (Box 7). In prescriptions for controlled drugs or those with a potential for abuse it is safer to write the strength and total amount in words, to prevent tampering. The patient was not a diabetic and suffered permanent brain damage as a result of taking the drug. The court indicated that a doctor owed a duty of care to a patient to write a prescription clearly and with sufficient legibility to allow for possible mistakes by a busy pharmacist. The court concluded that the word Amoxil on the prescription could have been read as Daonil. It found that the doctor had been in breach of his duty to write clearly and had been negligent. On appeal the doctor argued that the word on the prescription standing on its own could reasonably have been read incorrectly but that various other aspects of the prescription should have alerted the pharmacist. All of these factors should have raised doubts in the mind of the pharmacist and as a result he should have contacted the doctor. The implications of this ruling are that doctors are under a legal duty of care to write clearly, that is with sufficient legibility to allow for mistakes by others. When illegible handwriting results in a breach of that duty, causing personal injury, then the courts will be prepared to punish the careless by awarding sufficient damages. Source: J R Coll Gen Pract, 1989: 347-8 Dosage form and total amount Only use standard abbreviations that will be known to the pharmacist. All information following the S or the word ‘Label’ should be copied by the pharmacist onto the label of the package. This includes how much of the drug is to be taken, how often, and any specific instructions and warnings. When stating ‘as required’, the maximum dose and minimum dose interval should be indicated. Certain instructions for the pharmacist, such as ‘Add 5 ml measuring spoon’ are written here, but of course are not copied onto the label. Additional information may be added, such as the type of health insurance the patient has. The layout of the prescription form and the period of validity may vary between countries. As you can check for yourself, all prescriptions in this chapter include the basic information given above. As she has an appointment with him next week, and he is very busy, he advises you to halve the dose until then. You explain to her that the paracetamol does not work because she vomits the drug before it is absorbed. You prescribe paracetamol plus an anti- emetic suppository, metoclopramide, which she should take first, and wait 20-30 minutes before taking the paracetamol. Today his wife calls and asks you to come earlier because he is in considerable pain. Making sure not to underdose him, you start with 10 mg every six hours, with 20 mg at night. He also has non-insulin dependent diabetes, so you add a refill for his tolbutamide. There is nothing wrong with any of the four prescriptions (Figures 6, 7, 8 and 9). For the opiate for patient 32, the strength and the total amount have been written in words so they cannot easily be altered. In some countries it is mandatory to write an opiate prescription on a separate prescription sheet. She also has a newly diagnosed gastric ulcer, for which she has been prescribed another drug. As the doctor is explaining why she needs the new drug and how she should take it, her thoughts are drifting away.
Mattoo and Rathindran (2006) purchase levothroid 200 mcg otc thyroid gland cancer, for example generic levothroid 200mcg with visa thyroid gland where is it, highlight that for the United States 15 treatment that would show savings of $1. Some subsets of the population, such the Indian Diaspora, may prefer to go back ―home‖ for treatment, and may be happy to cross-subsidise some of the costs, or may not need an accompanying adult, further increasing the amount saved. Plausibly, the health systems within source countries could develop relations with off-shore medical tourism facilities to leverage cost savings – providing individuals with a choice of overseas destinations. This could also reduce waiting lists – and reflects a form of outsourcing or more ‗collective‘ medical travel (Smith et al. One of the drivers for medical tourism is price because treatments may often be available locally within the private sector, but at greater cost. There are arguments that some medical systems are inefficient and face restrictive barriers to entry. A development such as medical tourism can potentially exert competitive pressure on systems importing health care and help drive down the costs and prices offered in domestic systems (Herrick, 2007). Medical tourism may encourage economies to maximize their comparative advantage in labour costs, technology and/or capacity. We have seen in Section 4 that source counties – or those importing health services – may benefit from medical tourism through alleviating waiting lists and lowering healthcare costs, but may risk quality of care and legal liability. In this section we turn our attention to destination countries – or those exporting health services. Medical tourism has historically been from lower to higher income countries, with better medical facilities and more highly trained and qualified professionals. However, this trend is now reversing, and most recently ―hubs‖ of medical excellence have developed which attract people regionally (Horowitz et al. The main importing countries (those where the medical tourists come from) are in North America and Western Europe. Although current levels of movement are relatively limited, as outlined in Section Four , the potential, if payment was covered by third-party payers, is significant. The main exporting countries (those who provide the services to medical tourists) are located across all continents, including Latin America, Eastern Europe, Africa and Asia. For instance, Thailand and India specialise in orthopaedic and cardiac surgery, whereas Eastern European countries are hotspots for dental surgery (Smith et al. Nonetheless, many of the issues are quite generic and will affect any destination country, regardless of the level of economic development, just to a greater or lesser extent. It is also worth noting that the magnitude of the possible effects being discussed is largely unknown – in many cases the potential or actual occurrence of these effects has been observed, but the scale of effect, and how this scale may differ between countries is an unknown quantity (Smith et al. Most countries that engage in delivering care to medical tourists do so to increase the level of direct foreign exchange earnings coming into their country; to improve their balance-of-payments position (Timmermans, 2004, Ramírez de Arellano, 2007, Turner, 2007). To some extent this might be income thought of as accruing directly to the health system. For instance, in Singapore the authorities stress that involvement in medical tourism enables them to provide a broader range of clinical services to the indigenous population than would be the case if income was not being generated through medical tourism (India and Malta use such arguments) (Lee, 2010, Lee and Hung, 2010). Similarly, Ramírez de Arellano (2011) suggests that the Cuban experience is to reinvest income from foreign patients into the national system. It is therefore possible that some countries may seek foreign patients in order to develop facilities to better serve local patients (e. However, one must remember that foreign patients are merely an addition to domestic private patients; and this may be a significant or insignificant addition. There may also be different economic implications depending if these patients are simply using spare capacity or competing with domestic patients. For instance, the push by Thailand to be a hub for medical tourists in the 1990‘s was a result of the economic crisis in Asia generating a fall in domestic private patients and hence leading to spare capacity in their private sector. In this case, increasing foreign patients was more or less a net benefit to the private health system with substantial income and little real opportunity cost. However, where there is not spare capacity, and hence this capacity has to be developed, there are substantial potential costs in financial terms, but also in the wider context of fears of two-tier system developments, internal brain drain, etc. Although there may be income generated for the health sector, it is typically not health care income that concerns destination countries of course, but general increases in tourist income, since there is hoped to be a substantial level of expenditure by medical tourists, and their companions, that is not related to medical care (food, accommodation, sights, travel). Indeed, it is the promise of these earnings that often drives government involvement in investing directly or indirectly (tax incentives) in private hospitals and actively promoting medical tourism (Ramírez de Arellano, 2007, Reed, 2008, Lee, 2010). Indeed, the Indian government stated in its National Health Policy in 2002 that medical tourism was considered to be a ―deemed export‖ and therefore awarded it fiscal incentives, including lower import duties, prime land at subsidised rates and tax concessions (Garud, 2005, Ramírez de Arellano, 2007, Sengupta, 2008). Similarly, the Thai policy promoting medical tourism has been deemed to be such a success that it has recently been renewed.
Coma Check/ensure the airway is clear discount levothroid 200mcg without prescription underactive thyroid symptoms kelp, measure blood glucose level and assess level of consciousness (Blantyre or Glasgow coma scale) purchase levothroid 50 mcg with mastercard thyroid symptoms boils. In the event of hypoglycaemia or if blood glucose level cannot be measured, administer glucose. If the patient does not respond to administration of glucose, or if hypoglycaemia is not detected: – Exclude meningitis (lumbar puncture) or proceed directly to administration of an antibiotic (see Meningitis, Chapter 7). Oliguria and acute renal failure Look first for dehydration (Appendix 2), especially due to inadequate fluid intake or excessive fluid losses (high fever, vomiting, diarrhoea). Restrict fluids to 1 litre/day (30 ml/kg/day in children), plus additional volume equal to urine output. As with other methods for treating hypoglycaemia, maintain regular sugar intake, and monitor. Clinical features Inoculation may be followed by an immediate local reaction (trypanosomal chancre). Signs include intermittent fever, joint pain, lymphadenopathy (firm, mobile, painless lymph nodes, mainly cervical), hepatosplenomegaly and skin signs (facial oedema, pruritus). Signs of the haemolymphatic stage recede or disappear and varying neurological signs progressively develop: sensory disturbances (deep hyperaesthesia), psychiatric disorders (apathy or agitation), disturbance of the sleep cycle (with daytime somnolence alternating with insomnia at night), impaired motor functions (paralysis, seizures, tics) and neuroendocrine disorders (amenorrhoea, impotence). Patients often die of myocarditis in 3 to 6 months without having developed signs of the meningo- encephalitic stage. Patients receiving pentamidine can be treated as outpatients but those receiving suramin, eflornithine (with or without nifurtimox) or melarsoprol should be hospitalised. In the event of an anaphylactic reaction after the test dose, the patients must not be given suramin again. It is nonetheless recommended not to postpone the trypanocidal treatment for more than 10 days. Treatment in pregnant women All trypanocides are potentially toxic for the mother and the foetus (risk of miscarriage, malformation, etc. Prevention and control – Individual protection against tsetse fly bites: long sleeves and trousers, repellents, keeping away from risk areas (e. Transmission by contaminated blood transfusion and transplacental transmission are also possible. The disease is only found on the American continent in the area between the south of Mexico and the south of Argentina. Chronic phase – Follows a long latent period after the acute phase: cardiac lesions (arrhythmia and conduction disorders, cardiomyopathy, heart failure, chest pain, thromboembolism) and gastrointestinal lesions (megaoesophagus and megacolon). Laboratory Acute phase – Thin or thick film: detection of the parasite in blood or lymph nodes. In the event of purpura with fever, paraesthesia or peripheral polyneuritis, stop treament. Prevention – Improvement of housing and vector control: plastered walls and cement floors, corrugated- iron roofs, insecticide spraying. Clinical features Cutaneous and mucocutaneous leishmaniasis – Single or multiple lesions on the uncovered parts of the body: an erythematous papule 6 begins at the sandfly bite, enlarges to a nodule and extends in surface and depth to form a scabbed ulcer. Usually, lesions heal spontaneously, leaving a scar, and result in lifelong protection from disease. Visceral leishmaniasis Visceral leishmaniasis (kala azar) is a systemic disease, resulting in pancytopenia, immuno- suppression, and death if left untreated. Post-kala azar dermal leishmaniasis Macular, nodular or papular skin rash of unknown aetiology, particularly on the face, and typically occurring after apparent cure of visceral leishmaniasis. Laboratory Cutaneous and mucocutaneous leishmaniasis – Parasitological diagnosis: identification of Giemsa-stained parasites in smears of tissue biopsy from the edge of the ulcer. Splenic aspiration is the most sensitive technique but carries a theoretical risk of potentially fatal haemorrhage. For information: Cutaneous and mucocutaneous leishmaniasis – Cutaneous lesions generally heal spontaneously in 3 to 6 months.
