• A colleague of mine asked if I could ask the group if anyone has seen a lymphomatous/pseudolymphomatous reaction to a metal in a patient’s pacemaker wire? A 75 year old patient of his has developed a nodular reaction over the site of the scar where he previously had a pacemaker inserted in 2020. Despite multiple biopsies a diagnosis of…[Read more]

  • I think this is a difficult scenario.

    If there happened to be a delayed hypersensitivity to a component including dye of the tables, one would expect an eczematous reaction, or perhaps one of the less common systematic patterns of delayed hypersensitivity.

    I haven’t come across hair loss as a manifestation of delayed hypersensitivity to a drug…[Read more]

  • We are indebted to Deirdre Buckley for her sterling work and huge contribution to audit and publications for the BSCA committee. It is proposed a change in the constitution to reflect this, and formalise this role, to be voted on at the AGM June 2023.

  • Really interesting. Would it be delayed hypersensitivity if it is hair loss through oral consumption? To me it sounds more like side effect from a particular chemical, rather than a delayed hypersensitivity reaction.

  • Hi there,

    I was looking for some advice regarding the testing for edible dyes/ food colours.

    I have a patient who is thought to have a possible reaction to colours added to the tablets especially blue. Its an unusual scenario where she complained of excessive hair loss after the change in the tablets preparation. It was a trial medication which…[Read more]

    Johnnie Bourke raised this with the BSCA committee on Monday but no-one has yet said they can obtain them

  • Dear All

    Do you know whether we can get dipropylene glycol diacrylate to test patients to who have reacted to omnipod insulin pump?

    Thank you!

  • Graham Johnston replied to the topic TRUE test in the forum Questions 2 months ago

    Hi Susannah

    Doing a TRUE test to investigate suspected contact dermatitis is analagous to doing a punch biopsy of a melanoma

    It is against all current guidance because it carries a significant risk of missing important clinical information and so the potential to cause harm

    Those consultants who offer TRUE tests privately would vehemently…[Read more]

  • susannah george replied to the topic TRUE test in the forum Questions 2 months ago

    Thanks all. This is very helpful. However, our department is in crisis and we are at a point where many weeks there is no patch testing. So really the choice I have been given is use TRUE tests or not have a service. In this situation what would you do?

    The other thing I was wondering about was if it might be worth exploring the possibility of…[Read more]

  • Mark Wilkinson replied to the topic TRUE test in the forum Questions 2 months ago

    As David says the references underlying best practice are in the NICE approved BSCA/BAD Cutaneous Allergy Service Standards – a service providing TRUE test alone would not meet these. It might be worth highlighting 2 publications.

    This is a frequent idea/demand we have seen from Trusts and now also increasingly CCGs and ICNs

    They present it as care closer to home/the community but see it as a cost saving / secondary care referral reduction

    Patch testing was the first thing to be cancelled and the last thing to be reinstated with every lockdown during the pandemic. We have very few staff who are able to apply patch tests and so lists frequently get cancelled. Many of my consultant colleagues use TRUE tests privately and have proposed that we use these to reduce the waiting lists. Is…[Read more]
