In adolescents, it has been proposed that hypertension and pre-hypertension are diagnosed and classified using the same criteria as in adults.The value of routine screening for hypertension in children over the age of 3 years is debated. In 2004 the National High Blood Pressure Education Program recommended that children aged 3 years and older have blood pressure measurement at
least once at every health care visit and the National Heart, Lung, and Blood Institute and American Academy of Pediatrics made a similar recommendation. However, the American Academy of Family Physicians supports the view of the U.S. Preventive Services Task Force that the available evidence is insufficient to determine the balance of benefits and harms of screening for hypertension in children and adolescents who do not have symptoms. Prevention
Much of the disease burden of high blood pressure is experienced by people who are not labeled as hypertensive. Consequently, population strategies are required to reduce the consequences of high blood pressure and reduce the need for antihypertensive medications. Lifestyle changes are recommended to lower blood pressure, before starting medications. The 2004 British Hypertension Society guidelines proposed lifestyle changes consistent with those outlined by the US National High BP Education Program in 2002 for the primary prevention of hypertension:

maintain normal body weight for adults (e.g.
Schnitzler syndrome or Schnitzlers syndrome is a rare disease characterised by onset around middle age of chronic hives (urticaria) and periodic fever, bone pain and joint pain (sometimes with joint inflammation), weight loss, malaise, fatigue, swollen lymph glands and enlarged spleen and liver.Schnitzler syndrome is considered an autoinflammatory disorder and is generally treated with anakinra, which inhibits interleukin 1. This treatment controls the condition but does not cure it. Around 15% of people develop complications, but the condition generally does not shorten life. Classification
Schnitzler syndrome is a late-onset autoinflammatory disorder. Signs and symptoms
The typical onset is at around 55 years old, and the symptoms are recurrent hives, mostly on the torso and limbs, often with recurring fever, joint pain, bone pain, muscle pain, headache, fatigue, and loss of weight. Cause
As of 2017 the cause of the disease was not understood. Diagnosis
Blood tests show a high concentration of specific gamma-globulins (monoclonal gammopathy) of the IgM type. It almost always has light chains of the κ-type. A variant in which IgG is raised has been described, which appears to be one-tenth as common. The immunoglobulins may show up in the urine as Bence Jones proteins. Signs of inflammation are often present: these include an increased white blood cell count (leukocytosis) and a raised erythrocyte sedimentation rate and C-reactive protein. There can be anemia of chronic disease.
