Explanations of the etiology of asthma and triggers of acute asthma attacks
There are several different drug types used in the management of hypertension. This back to basics provides a useful summary of the different antihypertensive drug classes and how they act to regulate blood pressure.

Occupational asthma: how to help the wheezy workers
Approximately one in every ten cases of adult-onset asthma is attributable to
occupational exposure. Unless occupation is considered, a diagnosis of occupational
asthma will be missed so it is likely to be underdiagnosed. An average practice with
around 6,000 patients will typically have approximately 600 adult patients with asthma,
of whom 60 may have occupational asthma if we assume 10% of cases are related to
occupational exposure. Can you think of 60 patients with occupational asthma in your practice?
How to do an asthma review
UK primary care health professionals work under increasing demands and time
pressures. While a large proportion of their workload is demand-led (ie by patients
presenting with specific clinical problems), a significant amount of the work relates to
ongoing monitoring and care of patients with chronic illness. While most practices in
the UK achieve a high level of points in the Quality and Outcome Framework (QOF) for caring for
patients with asthma, the standard of the reviews for these patients may not reach a level
recommended in national and international guidelines. A structured approach may, therefore, be
helpful in ensuring quality of care for these patients. This article describes an approach to
reviewing patients with asthma, whether they present in surgery acutely, for follow-up of
uncontrolled episodes or for routine review.
How can I measure airways inflammation in asthma?
Asthma affects more than 5 million
people of all ages in the UK today.
The vast majority of asthma is
diagnosed and managed in primary
care and most people with asthma rarely need
to see a hospital specialist. Until recently it
has been difficult to measure the level of
inflammation seen in asthma accurately in
general practice. However, new techniques
such as exhaled nitric oxide measurement are
now available for use and this article provides
GP and nurse perspectives on the potential of
such techniques in primary care.
Getting it Right: Asthma Devices in Children
Asthma medications should routinely be delivered by a pressurised metered dose inhaler
(pMDI) and spacer system, with a facemask where necessary, in children under five,
according to the National Institute for Health and Clinical Excellence (NICE).1
For older children, aged 5-15 years, NICE has advised that a child’s therapeutic needs,
the ability to develop and maintain an effective technique, the suitability of a device for the
child’s and carer’s lifestyles (ie portability and convenience) and the likelihood of good
compliance are the factors that should govern the choice of device.2 Only once these factors
have been taken into account, should choice be made on the basis of cost minimisation.
Back to Basics: Is it COPD or asthma?
To be able to effectively manage patients with
airflow obstruction in general practice it is
imperative that we can differentiate between
asthma and chronic obstructive pulmonary disease
(COPD). Although COPD and asthma share many
clinical features, they are different conditions with
different airway inflammation and parenchymal
patterns.
Diagnosing allergy in asthma and allergic rhinitis
Patients with allergic asthma, intermittent (seasonal) or persistent (perennial) allergic
rhinitis, represent a significant proportion of primary care consultations. There is
growing awareness of allergy and the possibility of an allergic component as the cause
of a wide variety of symptoms. It is important to understand how to diagnose atopy to
ensure appropriate management and care of our patients. Diagnosing allergy is initially about
asking the right questions, followed by confirming or refuting the diagnosis by objective testing.
In this article, we explore history taking and objective testing that will help us to manage and
advise patients appropriately.
Back to Basics: Drugs for asthma – where and how do they work?
Bronchodilators in Children with Asthma
Asthma is a common condition in children, with approximately one in eight youngsters in
the UK receiving treatment for asthma at any given time. The British guidelines on the
management of asthma have separate pathways for children of different ages, for those
under 5 and for children aged 5-12 years. In this article, we review some of the
challenges of treating children with asthma, in particular, the best use of bronchodilators.
Why Optimise Inhaler Technique in Asthma and COPD?
Asthma UK estimates that 2.1 million patients in the UK are suffering unnecessarily because
they do not use their asthma treatment effectively. This article looks at how inhaled
therapies are deposited in the lungs, and at the basic differences between inhalers – with
a focus on optimising inhaler technique.
The problem with asthma…
The current treatment of asthma in the UK is rightfully seen as a triumph of chronic disease management within a primary care setting. Almost all routine asthma care and, increasingly, elements of acute asthma care, are now provided in general practice. Over the past twenty years, significant effort and investment have gone into the production […]
Which drugs are contraindicated for asthma patients
One person in every five households in the UK is receiving treatment for asthma,
according to latest figures. As well as treatment for asthma, many of these individuals
also self-medicate for minor illnesses or require prescribed medication for other
conditions. It is important that the drugs they take do not adversely affect their asthma
control. In this article we review which drugs might cause problems in patients also taking
treatment for asthma.
