Both outbreaks were found to be linked instances of vaccine-derived poliomyelitis. Europe
Europe was declared polio-free in 2002. Southeast Asia
The last case of polio in the region was in India (part of the WHOs South-East Asia Region) in January 2011. Since January 2011, there have been no reported cases of the wild polio infections in India, and in February 2012 the country was taken off the WHO list of polio endemic countries.On 27 March 2014, the WHO announced the eradication of poliomyelitis in the South-East Asia Region, which includes eleven countries: Bangladesh, Bhutan, North Korea, India, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka, Thailand and Timor-Leste. With the addition of this region, 80 per cent of the world population was considered to be living in polio-free regions. Middle East
In Syria difficulties in executing immunization programs in the ongoing civil war led to a return of polio, probably in 2012, acknowledged by the WHO in 2013. 15 cases were confirmed among children in Syria between October and November 2013 in Deir Ezzor. Later, two more cases, one each in rural Damascus and Aleppo, were identified. It was the first outbreak in Syria since 1999. Doctors and international public health agencies report more than 90 cases of polio in Syria, with fears of contagion in rebel areas from lack of sanitation and safe-water services. A vaccination campaign in Syria operated literally under fire and led to the deaths of several vaccinators, but returned vaccination coverage to pre-war levels.An outbreak of vaccine-derived polio was confirmed in 2017 in eastern Syria.
It signifies to the PR-depressions in a usual (but not always) association with downsloping TP segment in patients with acute pericarditis and is present in up to 80% of the patients affected with acute pericarditis. The sign is often best visualized in lead II and lateral precordial leads. In addition, Spodicks sign may also serve as an important distinguishing electrocardiographic tool between the acute pericarditis and acute coronary syndrome. The presence of a classical Spodicks sign is often a giveaway to the diagnosis.Rarely, electrical alternans may be seen, depending on the size of the effusion.A chest x-ray is usually normal in acute pericarditis but can reveal the presence of an enlarged heart if a pericardial effusion is present and is greater than 200 mL in volume. Conversely, patients with unexplained new onset cardiomegaly should always be worked up for acute pericarditis.An echocardiogram is typically normal in acute pericarditis but can reveal pericardial effusion, the presence of which supports the diagnosis, although its absence does not exclude the diagnosis. Treatment
Patients with uncomplicated acute pericarditis can generally be treated and followed up in an outpatient clinic. However, those with high risk factors for developing complications (see above) will need to be admitted to an inpatient service, most likely an ICU setting.
