The median number of cases tested per setting in survey settings was 547 discount phenergan 25 mg with amex, and ranged from 101 new cases in Mimika district in the Papua province of Indonesia to 1619 new cases in Viet Nam cheap 25 mg phenergan. The median number of new cases tested among the settings conducting surveillance was 485, and ranged from 7 cases in Iceland to 3379 in the United Kingdom. Thirteen settings reported prevalence of resistance to any drug of 30% or higher (Figure 1). Figure 1: Countries or settings with prevalence of any resistance higher than 30% among new cases, 2002–2007.

Baku City, Azerbaijan Republic of Moldova Donetsk Oblast, Ukraine Tomsk Oblast, Russian Fed Tashkent, Uzbekistan Estonia Mary El Oblast, Russian Fed Latvia Lithuania Armenia Orel Oblast, Russian Fed Inner Mongolia Auton. Sixteen settings reported a prevalence of isoniazid resistance 15% or higher among new cases (Figure 3). Tashkent, Uzbekistan Baku City, Azerbaijan Republic of Moldova Donetsk Oblast, Ukraine Latvia Armenia Tomsk Oblast, Russian Fed Mary El Oblast, Russian Fed Georgia Estonia Inner Mongolia Auton. The number of cases tested in settings conducting routine surveillance ranged from 1 (Iceland) to 522 (Poland), with a median of 58 cases per setting. The number of cases tested in settings conducting surveys ranged from 16 (Lebanon) to 1047 (Gujarat State, India) and 2054 cases in the Republic of Moldova19, with a median of 110. Any resistance among previously treated cases No resistance was reported in Iceland, Israel or Norway, where the number of previously treated cases was very small. In contrast, high prevalence of any resistance was seen in Baku City, Azerbaijan (84. In 16 settings, prevalence of any resistance was reported as 50% or higher (Figure 4).

Therefore, when estimating proportions of resistance among combined cases, proportions must be weighted by their population within the programme; this generates wide confidence levels. Rifampicin resistance unaccompanied by isoniazid resistance is rare, and may thus also be a good laboratory indicator. The median sample size was 335 for new cases, and ranged from 169 new cases in Cuba to 1809 in Peru. The median sample size was 264 for new cases, and ranged from 111 new cases in Jordan to 1049 in Morocco. A total of 30 countries conducted routine nationwide surveillance, with three settings in Spain. The median of combined cases tested was 483, and ranged from 8 in Iceland to 4800 in the United Kingdom. Data on previously treated cases were not included from the Mary El or Tomsk oblasts of the Russian Federation. Of the six countries, the median number of new cases tested was 547, and ranged from 101 in Mimika district in the Papua province of Indonesia to 1571 in Gujarat, India. India, Nepal and Myanmar showed similar proportions of resistance among re-treatment cases. Six countries reported data distinguished by treatment history, including four settings in mainland China. Among these settings, seven were able to report information for more than one year. The settings that reported were Cuba, Honduras, Latvia, Tomsk Oblast (Russian Federation), Barcelona and Galicia (Spain), Donetsk Oblast (Ukraine) and Uruguay. Data on new and previously treated cases were combined; data from multiple years were also combined if available. Data from the national laboratory registers in South Africa are included in the table, although these data are not considered nationally representative. Nineteen countries have reported at least one case since 2001, although no 24 Lyepshina S. Of the settings conducting routine surveillance, three countries and one oblast of the Russian Federation reported between 25 and 58 cases over a four-year period representing 6. Over a four-year period, Barcelona, Spain reported three cases and the Czech Republic reported five cases; these cases represented 8. During this time, Australia, France, Ireland, the Netherlands, Slovenia and Sweden reported one case; and Israel, Romania, and Canada reported two cases.
The development of symptoms in patients with mitral stenosis is attributable to either a critical increase in transmitral ﬂow buy phenergan 25 mg overnight delivery, or a de- crease in the diastolic ﬁlling period best phenergan 25mg, either or both of which can lead to an increase in left atrial and pulmonary venous pressures and the expression of dyspnea. The initial presentation of patients with even 2 mild-to-moderate mitral stenosis (mitral valve area 1. During the late stages of mitral stenosis, as pulmonary vascular resistance rises and cardiac output falls, fatigue or effort intolerance may play a dominant role. Alternatively, patients may “adapt” to the haemodynamic impairment and inadvertently curtail their activities to the extent that symptoms are minimized despite progressive 56 disease. There is no medical therapy available to reverse the mechanical ob- struction to mitral inﬂow. Because the left ventricle is protected from any volume or pressure load, there is no indication for empirical treatment in the asymptomatic patient with mild-to-moderate mitral stenosis and normal sinus rhythm. Symptoms of congestion can be treated with diuretics and salt restriction, though care is needed to avoid a critical fall in ﬁlling pressures, to the extent that cardiac output and peripheral perfusion suffer. Digoxin is of no proven beneﬁt in patients with normal sinus rhythm and preserved left ventricular systolic function. Beta-blockers and rate-slowing calcium channel antagonists may be of beneﬁt in some patients by slowing the heart response to exercise. The treatment of haemoptysis must be directed at the root cause, which can vary from pulmonary edema to bronchitis; measures to reduce left atrial and pulmonary venous pressures may be appro- priate. Patients with severe stenosis or symptoms of such should be advised against strenuous physical activities (9). Under such conditions, there is the potential for a sudden increase in left atrial pressure, especially with rapid ventricu- lar rates due to a critical decrease in diastolic ﬁlling times, and the potential for a signiﬁcant increase in the associated risk of throm- boembolism. Among the acquired heart valve lesions, mitral stenosis is associated with the highest risk of systemic thromboembolism. The incidence of systemic embolization, including stroke, among patients with rheu- matic mitral valve disease has been estimated at 1. Patients who suffer a ﬁrst embolus are at increased risk for a second, particularly within the next six months. Despite claims to the contrary, there are no prospective data to 57 support the contention that successful valvuloplasty (surgical or bal- loon) obviates the need for long-term anticoagulation therapy in pa- tients who have had an embolus (9). Observational studies have reported signiﬁcant reductions in the incidence of recurrent emboli among patients treated long-term with warfarin anticoagulation, from rates of approximately 5% per year in untreated patients, to 0. In each of these studies, the patients who beneﬁted most from anticoagulant treatment were those at highest risk for embolic events. In all instances, a precipitating cause (fever, anemia, thyrotoxicosis) should be identiﬁed and treated. Slowing the ventri- cular response and providing a diuretic can often restore clinical stability. Agents useful for slowing the ventricular response include beta-blockers, the non-dihydropyridine calcium channel antagonists (diltiazem, verapamil), and digoxin. Beta-blockers and diuretics can be used in pregnant women with little risk to the fetus. If a left atrial thrombus is identiﬁed, patients should receive at least three weeks of therapeutic warfarin anticoagulation and undergo repeat trans-oesophageal echocardiography before cardioversion. With either of these two strategies, warfarin anticoagulation is recommended indeﬁnitely 58 thereafter (when feasible), as would also be the case for any patient with a history of prior embolization independent of rhythm. If indeﬁ- nite anticoagulation is not feasible, a 3–4 week post-cardioversion course is advised (when feasible) to decrease the incidence of embo- lization during the delayed recovery of the left atrial mechanical function. The empirical use of warfarin as prophylaxis against a ﬁrst embolus in patients with moderate or severe mitral stenosis, left atrial enlargement (>5. These drugs are not readily available in many areas and their electrophysiological effects can be very difﬁcult to monitor. The late stages of uncorrected, severe mitral stenosis may be compli- cated by the development of pulmonary hypertension, and by failure of the right side of the heart, with edema and ascites. Tricuspid regurgitation commonly co-exists and is more often secondary to right ventricular dilatation, than to primary rheumatic involvement. Digoxin is the preferred agent to control ventricular rate; beta-blockers and rate-slowing calcium channel 59 antagonists have negative inotropic effects that could be deleterious in this setting. Nutritional efforts to protect against hypoalbuminemia and the use of graduated compression stockings are also helpful. Mitral regurgitation The volume load of chronic mitral regurgitation can be well tolerated for several years. Indeed, the favourable loading conditions may ob- scure the recognition of left ventricular contractile dysfunction until relatively late in the natural history.
