A recent venom allergy guideline¹ published by the British Society for Allergy and Clinical Immunology (BSACI) this year, makes interesting reading. They report a lifetime-risk between 60 and 90% for the UK population of being stung by a wasp (Vespid) or bee (Apis). Of those stung, up to 26% will report large painful local reactions, but significant allergic reactions only [...]
Urban air pollution is a serious public health hazard and has been associated with exacerbations of chronic respiratory illnesses due to airway mucus membrane irritation and increased oxidative stress. However no convincing link between air pollution and allergic sensitisation has been shown in the scientific literature. We know that nitrogen dioxide, ozone and diesel exhaust [...]
Recent medical research shows that our middle-class obsession with cleanliness and avoiding weaning until late in infancy has rebounded in a western-world epidemic of childhood wheezing, sneezing and eczema with seven fold increases in peanut, cat, dust mite and pollen allergies. We are now encouraged rather to throw the cat in the cot, smother the baby [...]
Allergy to red mammalian meat is relatively common in Africa and so are tick bites. I was recently shown a study by Platts Mills et al from USA in 2011 in which they suggested there may be a link between tick bites by the Amblyomma species of North American tick and the development of IgE [...]
Many people develop debilitating patches of dermatitis after contact with various common environmental chemicals and agent in cleaning materials. This type of reaction by the skin immune system results in a Type 4 delayed hypersensitivity reaction with rashing. A common contact allergy occuring in 20% of women is to the metal nickel found in clothing [...]
Many different so-called wonder-cures for hay fever have come and gone over the years. This is particularly evident online, as one searches for a drug-free natural alternative to conventional hay fever medication. The problem is that many of these remedies, which sound attractive at face value , have no track record or clinical evidence base. [...]
Spring has suddenly broken through the icy winter and the trees are covered in blossom this April. But this is a time of discomfort and suffering for those tree pollen allergic hay fever sufferers who will experience itching, sneezing, watering nose and irritatingly painful eyes. Silver birch pollen will be pouring from dangling catkins suspended [...]
Conventional first line treatments for hayfever and allergic eyes (conjunctivitis) are non-sedating antihistamine medication. However there is growing evidence that topical nasal sprays containing low dose steroids control both nasal symptoms (such as congestion, rhinorrhoea, sneezing and itching) and eye symptoms (such as itching/ burning, tearing/watering and redness) in persistent allergic rhinitis and conjunctivitis. The recommended [...]
It’s early February and with the cold weather one forgets that Spring is around the corner. Now is the time to proactively prepare for the hay fever season. First of all the tree pollens will arrive with Silver Birch tree pollen being the main culprit and those sensitive to this aeroallergen will get typical hay [...]
Many surgical procedures involve implanting artificial metallic components such as joint replacements (arthroplasties), plates, screws and internal “plumbing” that contain metals such as titanium, nickel, cobalt and other heavy metal alloys. Ever since mercury dental amalgam was thought to be a health hazard in the 1970’s, people have become very aware of possible side effects [...]
