[Hypertension in the elderly]

Many aspects of hypertension diagnosis and treatment are similar in young and old patients. However, some differences exist. Due to the increasing vascular stiffness most elderly patients have isolated systolic hypertension and its prevalence in the population is high. Blood pressure should be measured in the sitting position and also with the patient standing to exclude orthostatic hypotension, a frequent problem in elderly patients. Pseudohypertension, a source of inadequate measurements in elderly patients, should be recognized. In comparison to other health problems there is good scientific evidence for antihypertensive treatment in elderly patients. As treatment does not only improve survival, but also reduces cardiovascular events such as non-fatal stroke or myocardial infarction, antihypertensive therapy is an important measure to prevent functional decline and disability.

Traumatic brain injury in children

The general practitioner has an important role in the acute management and during the rehabilitation process of children after a traumatic head injury. Latest research shows that sequelae may occur even after a mild head injury without loss of consciousness. Recognizing the warning signs and symptoms after a head injury allows the general practitioner to counsel the child and parents in secondary prevention, particularly in order to avoid any further head injury during the recovery phase. Under the supervision of the general practitioner, a gradual progressive return to the child's everyday activities optimizes the chances of a rapid and complete recovery.

[Arterial-ischaemic stroke in childhood]

The risk to have a stroke during childhood is at least as frequent as to suffer from a brain tumour. Unlike adults, in whom ischaemic strokes overweigh haemorrhagic strokes, ischaemic and haemorrhagic strokes are equally frequent in children, occurring with an incidence of 2 - 3/100'000 children/year. Even though the clinical presentation of arterial-ischaemic stroke in children (pedAIS) is similar to adults, time to diagnosis is longer. The delay to diagnosis is mainly explained by the low index of suspicion of both the general population and the medical personnel, a broad range of differential diagnoses, and the fact that diagnostic imaging in children often requires sedation, which is not always readily available. PedAIS is a multiple risk problem, usually occurring due to a combination of risk factors, such as infectious diseases, dehydration, trauma or an underlying condition such as congenital heart disease. Still little is known about the appropriate management of pedAIS. Supportive measures are considered to be the mainstay of therapy. The use of antithrombotic medication depends on pedAIS aetiology. In an ongoing multicenter trial, the safety and effectiveness of thrombolysis are currently being investigated. PedAIS carries an important mortality and morbidity, with neurological and neuropsychological deficits persisting in two thirds of the affected children.

[Childhood's determinants for high blood pressure in adulthood]

Hypertension has been estimated to affect 20 - 25% of the adult population and represents an important risk factor for cardiovascular disease like coronary heart disease, stroke and peripheral artery occlusive disease. In addition, hypertension supports the development and progression of chronic kidney insufficiency. The interaction of multiple genetic and environmental factors are felt to influence the level of blood pressure. Epidemiological data in the sixties and seventies demonstrated a correlation between cardiovascular disease and infant mortality in the same population. In the late eighties Barker and coworkers described a strong correlation between low birth weight and increased risk for the development of cardiovascular complications. It has been supposed that factors influencing the intrauterine growth and development can lead to adult cardiovascular diseases, known as the concept of "fetal programming". Beside the effect of fetal programming, multiple (preventable and non-preventable) factors determine the blood pressure level in childhood, which will define adult blood pressure level through the blood pressure tracking from childhood to adulthood. Hence, the prevention of cardiovascular disease in adulthood begins in childhood through identification of preventable risk factors as for example obesity and passive smoking and recognition of risk groups like small for gestational age or preterm children.

Thoraxschmerzen bei Kindern und Jugendlichen - das Herz?

Chest pain in children and adolescents is a frequent observation, although potentially relevant disease is rather rare and then found in situations with acute presentation. In children with an inflammatory/infectious clinical context the differential diagnosis is oesophagitis, pleuropneumonia or pericarditis. Potentially dangerous complications may be found in youth with predisposing conditions for aortic dissection, pneumothorax or pulmonary embolism, or even in rare instances for an acute coronary complication. In these cases aggressive diagnostic work-up is mandatory. In the frequent elective outpatient evaluation of teenagers with long-lasting episodes of chest pain, relevant underlying cardiovascular disease only rarely can be found as the cause. In the elective outpatient evaluation for chest pain, usually patient history and clinical examination may be enough to track the problem, the main role of the physician is to provide reassurance with minimal but appropriate testing.

The Long-Term Multicenter Observational Study of Dabigatran Treatment in Patients With Atrial Fibrillation (RELY-ABLE) Study

During follow-up of between 1 and 3 years in the Randomized Evaluation of Long-term Anticoagulation Therapy (RE-LY) trial, 2 doses of dabigatran etexilate were shown to be effective and safe for the prevention of stroke or systemic embolism in patients with atrial fibrillation. There is a need for longer-term follow-up of patients on dabigatran and for further data comparing the 2 dabigatran doses.
