In 1981, the World Health Organization established the Action Programme on Essential Drugs to support countries to implementing national drug policies and to work towards rational use of drugs. Appropriate tools are critical to the effective implementation of essential drugs policies. Designed to give practical, concise information to physicians, pharmacists and nurses, this “Essential drugs - practical guidelines” is an important contribution from Médecins Sans Frontières to improve the rational use of drugs, which will be a continuing challenge in the coming years. Quick Director, Essential Drugs and Other medicines World Health Organization Foreword This guide is not a dictionary of pharmacological agents. It is a practical manual intended for health professionals, physicians, pharmacists, nurses and health auxiliaries involved in curative care and drug management. This manual is not only used by Médecins Sans Frontières, but also in a wide range of other programmes and contexts. These medicines have been included in this guide by entries marked by a grey diagonal line. The entries are classified according to the route of administration and in alphabetical order. This classification reflects the drug management system proposed in this manual (see Organization and management of a pharmacy). Only the main contra-indications, adverse effects, precautions and drug interactions of each drug have been indicated in this manual. Concerning antiretrovirals, the interactions are too many to be listed: it is therefore essential to refer to specialised literature. This manual is a collective effort by medical professionals from many disciplines, all with field experience. Despite all efforts, it is possible that certain errors may have been overlooked in this manual. The authors would be grateful for any comments or criticisms to ensure that this manual continues to evolve and remains adapted to the reality of the field.

Exclusion periods are provided in Chapter 9 - Management of Specifc Infectious Diseases - under the relevant infectious diseases discount 50mg zoloft otc. Infectious Diseases Relevant to Staff The following are diseases relevant to staff zoloft 25mg line. As already stated above purchase zoloft 50 mg online, immunisation should be in accordance with national immunisation guidelines. Those whose bloods test shows that they are not immune should be offered vaccination. There is no indication for school staff elsewhere to receive hepatitis B vaccine routinely since good implementation of standard precautions should provide adequate protection against blood and body fuid exposure (see Chapter 3). Furthermore, now that hepatitis B vaccine has been included in the routine childhood immunisation schedule, vaccinated children should not pose a risk in the future. There is no need for staff with chronic hepatitis B infection to be excluded from working in a school setting. As a result, staff who are pregnant or in another recognised risk group for infuenza should ensure that they are fully immunised against infuenza (risk groups for seasonal infuenza can be found on the website of the National Immunisation Offce at http://www. Infection with measles during pregnancy can result in early delivery or even loss of the baby. Rubella may have devastating consequences on the developing baby if a non-immune mother is exposed in early pregnancy. This protects the baby for the frst few months of life, before the baby is fully vaccinated. Slapped Cheek Syndrome (Fifth Disease - Parvovirus B19) Slapped cheek syndrome is usually a mild self-limiting viral illness caused by parvovirus B19. It is very common in childhood and therefore most adults have been infected and are immune to parvovirus. Simple hygiene measures including scrupulous hand washing provide the most effective method of prevention and control of this viral disease. Staff with these conditions should seek medical advice if they believe they may have been exposed to a case either at home, in the community or at work. Staff should be encouraged to report such symptoms and seek medical advice should they arise. This is especially important for staff who are involved in preparation or serving of food. Special circumstances • Pregnant staff It is important that staff of childbearing age should ensure that they are appropriately immunised and compliant with infection control precautions, as outlined in Chapter 3. Slapped Cheek Syndrome (Parvovirus B19) Slapped cheek syndrome is usually a mild self-limiting viral illness, caused by parvovirus B19 that is very common in childhood. Most pregnant women, especially women who work with children, are already immune to parvovirus and therefore do not become infected. Infection is more likely after contact with an infectious person in a household setting rather than an occupational (school) setting. For a small number of women who develop infection, the infection may pass to the foetus. Pregnant women, who may have been exposed to a case either at home, in the community or at work, should inform their doctor so that follow-up, if required, can be arranged. Simple hygiene measures including scrupulous hand washing and avoiding sharing eating and drinking utensils provide the most effective method of prevention and control of this viral disease. Circulation of parvovirus in schools refects circulation of the infection in the wider community. In addition by the time someone develops the typical rash of slapped cheek syndrome they are usually no longer infectious and their contacts have already been exposed. Exclusion: An affected staff member or pupil need not be excluded because he/she is no longer infectious by the time the rash occurs. Pregnant women who are occupationally exposed to children under 6 have a slightly increased infection risk, especially in the frst years of their career. In non outbreak periods it is pregnant women who have contact with children at home who have the highest risk of a new infection in pregnancy. During outbreak periods current evidence does not support exclusion from work for seronegative pregnant women who have occupational contact with children. However, individual risk assessment should consider the following when deciding on exclusion from work: • Is the outbreak laboratory confrmed and ongoing • Is there close contact with children under 6 years of age (usually junior & senior infants and frst class) but no close contact with children outside this work setting • The stage of pregnancy as in the rare situations when exclusion from work is considered , this should not usually be extended beyond the peak period of risk i. Germs are everywhere and are introduced into school settings in a variety of ways e. Viruses, in particular, can be shed in large numbers in respiratory secretions and in faeces and can survive on surfaces for days, or in the case of certain viruses such as norovirus (the virus responsible for winter vomiting illness), for weeks. Environmental hygiene is therefore a vital part of good infection prevention and control. Terminology Cleaning is a mechanical process (scrubbing) using detergent and water to remove food residues, dirt, debris and grease. Disinfectants are chemicals that will reduce the number of germs to a level at which they are not harmful. Normal cleaning methods, using household detergents and warm water is considered to be suffcient to reduce the number of germs in the environment to a safe level.

If this bias is present generic zoloft 50mg with mastercard, the test will appear to work better than it otherwise would in an uncontrolled clinical situation purchase 100mg zoloft mastercard. In test review bias 50 mg zoloft fast delivery, the person interpreting the tests has prior knowledge of the patient’s outcome or their result on the gold-standard test. Therefore, they may be more likely to interpret the test so that it confirms the already known diagnosis. This is because he or she knows that there is a heart attack in that area that should show up with an area of diminished blood flow to some of the heart muscle. In diagnostic review bias, the person interpreting the gold-standard test knows the result of the diagnostic test. This may change the interpretation of the gold standard, and make the diagnostic test look better since the reviewer will make it concur with the gold standard more often. This will not occur if the gold-standard test is completely objective by being totally automated with 300 Essential Evidence-Based Medicine a dichotomous result or if the interpreter of the gold standard is blinded to the results of the diagnostic test. For example, a patient with a positive ultrasound of the leg veins is diagnosed with deep venous thrombosis or a blood clot in the veins. A radiologist reading the venogram, dye assisted x-ray of the veins, which is the gold standard in this case, is more likely to read an equivocal area as one showing blockage since he or she knows that the diagnostic test showed an area consistent with a clot. The person interpreting the test will base their reading of the test upon known clinical information. Radiologists are more likely to read pneumonia on a chest x-ray if they are told that the patient has classical findings of pneumonia such as cough, fever, and localized rales over one part of the lungs on examination. In daily clinical situations, this will make the correlation between clinical data and test results seem better than they may be in a situation in which the radiologist is given no clinical information, but asked only to interpret the x-ray findings. Miscellaneous sources of bias Indeterminate and uninterpretable results Some tests have results that are not always clearly positive or negative, but may be unclear, indeterminate, or uninterpretable. If these are classified as positive or negative, the characteristics of the test will be changed. This makes calculation and manipulation of likelihood ratios or sensitivity and specificity much more complicated since categories are no longer dichotomous, but have other possible outcomes. For example, some patients with pulmonary emboli have an indeterminate perfusion–ventilation lung scan showing the distribution of radioactive mate- rial in the lung. This means that the results are neither positive nor negative and the clinician is unsure about how to proceed. This is more likely to occur if the appendix lies in an unusual location such as in the pelvis or retrocecal area. In cases of patients who actually have the dis- ease, if the result is classified as positive, the patient will be correctly classi- fied. If however, the result is classified as negative, the patient will be incorrectly classified. Again the need for blinded reading and careful a-priori definitions of a positive and negative test can prevent the errors that go with this type of problem. Tests that are operator- dependent are most prone to error because of lack of reproducibility. They may perform very well when carried out in a research setting, but when extrapolated to the community setting, the persons performing them may never rise to the level of expertise required, either because they don’t do enough of the tests to become really proficient or because they lack the enthusiasm or interest. When tested in a center that was doing research on this use, they performed very well. Tests initially studied in one center should be studied in a wide variety of other settings before the results of their operating characteristics are accepted. Post-hoc selection of test positivity criteria This situation is often seen when a continuous variable is converted to a dichoto- mous one for purposes of defining the cutoff between normal and abnormal. In studying the test, it is discovered that most patients with the disease being sought have a test value above a certain threshold and most without the disease have a test value below that threshold. There is statistical significance for the difference in disease occurrence in these two groups (P < 0. In some cases, the researchers looked at several cutoff points before deciding on a final one. A validation study should be done to verify this result and the results given as like- lihood ratios rather than simple differences and P values. This problem can be evaluated by using likelihood ratios and sensitivity and specificity and plotting them on the Receiver Operating Characteristics curve for the data rather than using only statistical significance as the defining variables in test performance. Temporal changes Test characteristics measured at one point in time may change as the test is tech- nically improved. The measures calculated from the studies of the newer tech- nology will not apply to the older technology. Look for this problem in the use of newer biochemical or patho- logical tests, as well as in questionnaire tests if the questionnaire is constantly being improved. There may also be problems associated with the technologi- cal improvement in tests.

For lengths between the 3rd and 97th percentiles generic zoloft 50mg on line, the median and range of weights defined by the 3rd and 97th weight-for-length percentiles for children 0 to 3 years of age are presented in Tables 5-6 (boys) and 5-7 (girls) (Kuczmarski et al discount zoloft 25 mg. It is unlikely that body composition to any important extent affects energy expenditure at rest or the energy costs of physical activities among adults with body mass indexes from 18 zoloft 25mg amex. In adults with higher percentages of body fat composition, mechanical hindrances can increase the energy expenditure associated with certain types of activity. Cross-sectionally, Goran and coworkers (1995a) and Griffiths and Payne (1976) reported significantly lower resting energy expenditure in children born to one or both overweight parents when the children were not themselves overweight. As such, these data are consis- tent with the general view that obesity is a multifactor problem. The question of whether obese individuals may have decreased energy requirements after weight loss, a factor that would help explain the com- mon phenomenon of weight regain following weight loss, has also been investigated. Notable exceptions to the latter conclusion are from studies of Amatruda and colleagues (1993) and Weinsier and colleagues (2000), which compared individuals longitudinally over the course of weight loss with a cross- sectional, never-obese control group. The combination of these data from different types of studies does not permit any general conclusion at the current time, and further studies in this area are needed. Physical Activity The impact of physical activity on energy expenditure is discussed briefly here and in more detail in Chapter 12. Given that the basal oxygen (O2) consumption rate of adults is approximately 250 mL/min, and that athletes such as elite marathon runners can sustain O2 consumption rates of 5,000 mL/min, the scale of metabolic responses to exercise varies over a 20-fold range. The increase in energy expenditure elicited while physical activities take place accounts for the largest part of the effect of physical activity on overall energy expenditure, which is the product of the cost of particular activities and their duration (see Table 12-1 for examples of the energy cost of typical activities). Effect of Exercise on Postexercise Energy Expenditure In addition to the immediate energy cost of individual activities, physi- cal activity also affects energy expenditure in the post-exercise period. Excess postexercise O2 consumption depends on exercise intensity and duration as well as other factors, such as environmental temperatures, state of hydration, and degree of trauma, demonstrable sometimes up to 24 hours after exercise (Bahr et al. In one study, residual effects of exercise could be seen following 15 hours of exercise, but not after 30 hours (Herring et al. There may also be chronic changes in energy expenditure associated with regular physical activity as a result of changes in body composition and alterations in the metabolic rate of muscle tissue, neuroendocrine status, and changes in spontaneous physical activity associated with altered levels of fitness (van Baak, 1999; Webber and Macdonald, 2000). However, the magnitude and direction of change in energy expenditure associated with these factors remain controversial due to the variable effects of exer- cise on the coupling of oxidative phosphorylation in mitochondria, on ion shifts, on substrates, and on other factors (Gaesser and Brooks, 1984). Spontaneous Nonexercise Activity Spontaneous nonexercise activity has been reported to be quantita- tively important, accounting for 100 to 700 kcal/d, even in subjects resid- ing in a whole-body calorimeter chamber (Ravussin et al. Sitting without or with fidgeting raises energy expenditure by 4 or 54 percent respectively, compared to lying supine (Levine et al. This suggests that the subjects had lower levels of spontaneous movement after strenuous exercise because they were more tired. Similarly, Blaak and coworkers (1992) reported no measurable change in spontaneous physical activity in obese boys enrolled in an exercise-training program. The combination of these different results indicates that the effects of planned physical activity on activity at other times are highly variable (ranging from overall positive to negative effects on overall energy expen- diture). This most likely depends on a number of factors, including the nature of the exercise (strenuous versus moderate), the initial fitness of the subjects, body composition, and gender. Gender There are substantial data on the effects of gender on energy expendi- ture throughout the lifespan. Although the energy requirement for growth relative to mainte- nance is low, except for the first months of life, satisfactory growth is a sensitive indicator of whether energy needs are being met. The energy cost of growth as a percentage of total energy requirements decreases from around 35 percent at 1 month to 3 percent at 12 months of age, and remains low until the pubertal growth spurt, at which time it increases to about 4 percent (Butte, 2000). Infants double their birth weight by 6 months of age, and triple it by 12 months (Butte et al. Progressive fat deposi- tion in the early months results in a peak in the percentage body weight that is fat at 3 to 6 months (about 31 percent) and body fatness sub- sequently declines to an average of 27 percent at 12 months (Butte et al. During infancy and childhood, girls grow slightly slower than boys, and girls have slightly more body fat (Butte et al. During adoles- cence the gender differences in body composition are accentuated (Ellis, 1997; Ellis et al. Growth velocity is a sensitive indicator of energy status and use of growth velocity charts will detect growth faltering earlier than detected using attained growth charts. Problems with measurement precision and high variabil- ity in individual growth rates over short time periods complicate the inter- pretation of growth velocity data. The timing of the adolescent growth spurt, which typically lasts 2 to 3 years, is also very variable, with the onset typically between 10 and 13 years of age in the majority of children (Forbes, 1987; Tanner, 1955). In general, weight velocity reflects acute episodes of dietary intake, whereas length velocity is affected by chronic factors. The suggested breakpoint for a more rapid decline apparently occurs around 40 years of age in men and 50 years of age in women (Poehlman, 1992, 1993). All of these determinants of energy requirements are potentially influenced by genetic inheritance, with trans- missible and nontransmissible cultural factors contributing to variability as well. Currently there is insufficient research data to predict differences in energy requirements among specific genetic groups, but as data accumu- late this may become possible.
