The most devastating effects are on children and young adults in their most productive years. For at least ﬁve decades this unique non-suppurative sequel to group A streptococcal infections has been a concern of the World Health Organization and its member countries. Without doubt, appropriate public health control programs and optimal medical care reduce the burden of disease (1–6). Although the responsible pathogenic mechanism(s) still remain in- completely deﬁned, methods for optimal prevention and manage- ment have changed during the past ﬁfteen years (5–8). Every attempt has been made to make this a practically useful document and at the same time to furnish appropriate references with additional information for the practitioner. The economic effects of the disability and premature death caused by these diseases are felt at both the individual and national levels through higher direct and indirect health-care costs. Group A streptococcal infections Beta-haemolytic streptococci can be divided into a number of sero- logical groups on the basis of their cell-wall polysaccharide antigen. Those in serological group A (Streptococcus pyogenes) can be further subdivided into more than 130 distinct M types, and are responsible for the vast majority of infections in humans (7–9). B, C, G and F) have been isolated from human subjects and are some- times associated with infection; and streptococci in groups C and G can produce extracellular antigens (including streptolysin-O) with similar characteristics to that produced by group A streptococci (7–9). In both developing and developed countries, pharyngitis and skin infection (impetigo) are the most common infections caused by group A streptococci. Group A streptococci are the most common bacterial cause of pharyngitis, with a peak incidence in children 5–15 years of age (3, 5, 7, 9). Streptococcal pharyngitis is less frequent among chil- dren in the ﬁrst three years of life and among adults. It has been estimated that most children develop at least one episode of pharyn- gitis per year, 15–20% of which are caused by group A streptococci and nearly 80% by viral pathogens (1, 5, 7, 9). The incidence of pharyngeal beta-haemolytic streptococcal infections can vary be- tween countries and within the same country, depending upon season, age group, socioeconomic conditions, environmental factors and the quality of health care (1–3, 5, 10, 11). Surveys of healthy schoolchil- dren 6–10 years of age, for example, found anti-streptolysin-O titres >200 Todd units in 15–70% of the children (2), while other studies 3 reported beta-haemolytic streptococci carrier rates of 10–50% for asymptomatic schoolchildren (1, 2). In temperate countries, 50–60% of streptococci isolated from asymptomatic children belong to sero- logical group A, while streptococci in serological groups C and G together occur in less than 30% of the children. Conversely, in many tropical countries, groups C and G streptococci occur with rates as high as 60–70% in asymptomatic carriers (1–3, 5, 11).
Pharmacokinetics: 10 to 20 percent of the active compound reaches the lungs purchase rogaine 2 60 ml free shipping, the rest is deposited in the oropharynx buy rogaine 2 60 ml low price. Warning: zanamivir is not recommended for the treatment of patients with under- lying airways disease (such as asthma or chronic obstructive pulmonary disease) purchase rogaine 2 60 ml on-line. Interactions: no clinically significant pharmacokinetic drug interactions are pre- dicted based on data from in vitro studies purchase 60 ml rogaine 2 overnight delivery. Side effects: zanamivir has a good safety profile and the overall risk for any respi- ratory event is low. Patient information: the use of zanamivir for the treatment of influenza has not been shown to reduce the risk of transmission of influenza to others. There is a risk of bronchospasm, especially in the setting of underlying airways disease, and patients should stop zanamivir and contact their physician if they expe- rience increased respiratory symptoms during treatment such as worsening wheez- ing, shortness of breath, or other signs or symptoms of bronchospasm. A patient with asthma or chronic obstructive pulmonary disease must be made aware of the risks and should have a fast-acting bronchodilator available. Patients scheduled to take inhaled bronchodilators at the same time as zanamivir should be advised to use their bronchodilators before taking zanamivir.

There is concern that these strains could spread around the world, stressing the need for additional control measures, such as new diagnostic methods, better drugs for treatment, and a more effective vaccine. Furthermore, global drug resistance surveillance identifies areas of high resistance, warning the health authorities to initiate the appropriate correction measures. The third and last report available, published in 2004, covers data from 77 settings and had the main goal of expanding knowledge of the prevalent global patterns of resistance and exploring trends in resistance over time. The prevalence of resistance among previously untreated patients also reflects program performance over a long period of time and indicates the level of transmission within the community. The prevalence of drug resistance among patients with a history of previous treatment, on the other hand, has re- ceived less attention, since surveillance of this population is more complex. Re- treatment patients are a heterogeneous group composed of chronic patients, those with treatment failure, those who have relapsed, and those who have returned after defaulting. One of the recommendations of the last report is that all subgroups of re-treatment cases be notified separately and their outcomes reported; furthermore, surveillance of resistance should be conducted on a representative sample of this population. Trends in drug resistance were determined in 46 settings (20 with two data points and 26 with at least three). Significant increases in prevalence of any resistance were found in Botswana, New Zealand, Poland, and Tomsk Oblast (Russian Federation). Among previously treated cases with data available from 66 settings (8,405 pa- tients) the median prevalence of resistance to at least one drug (any resistance) was 18. Countries of the former Soviet Union had a median prevalence of resistance to the four drugs of 30 %, compared with 1. However, these data should be interpreted with caution given the small number of subjects tested in some settings.
