Prevention of Allergy

The development of allergy is a very complex issue that involves both genes and environmental influences. Science is still trying to discover the mechanisms for the development of allergy.

One of the discovery from medical studies is that the use of hydrolyzed formula can help prevent allergy. It is important to chose the formula with proven medical evidence.  By referring to the GINI study, the use of partially hydrolyzed formula Nan HA can prevent eczema if exclusive breast feeding cannot be done. The extensively hydrolyzed casein formula Nutramigen also has data showing that it can prevent eczema; but this special formula is primarily used for instances of cow milk allergy.

Atopic Dermatitis (Eczema) and Bathing

Bathing is an important part of Atopic Dermatitis care. Bathing can remove dirt, allergens and microbes from the skin. However, it is important to understand that bathing alone is not adequate. Bathing can actually dry out the skin by removing natural oils from the skin and cause the Atopic Dermatitis to flare. Also using harsh soaps, scented soaps and lotions during bathing can significantly irritate the skin and dry out the skin.

So it is very important to use mild unscented soaps for bathing such as Dove unscented beauty soap bar or gentle cleansers such as Aquaphor Gentle Wash, Aveeno Advanced Care Wash  and Cetaphil Gentle Cleansing Bar. After bathing, do not forget the lock in the moisture by applying appropriate barrier creams immediately onto the skin.

Patients with severe Atopic Dermatitis should see a qualified Allergist to determine the triggers that can cause the Atopic Dermatitis to flare.

Wangi Mudarat / Perfume Allergy

Patients with respiratory allergies such as allergic rhinitis and asthma can have their diseases exacerbated by perfume. Perfume particles evaporate and become airborne giving perfumes their smell. Patients with allergic inflammation in their airways have airway hyper-reactivity and can easily become irritated by inhalation of perfume leading to symptoms such as blocked nose, runny nose, sneezing, coughing and wheezing. An asthmatic who begins to cough and wheeze upon exposure to perfume suggests uncontrolled asthma.

Another manifestation of perfume allergy is allergic contact dermatitis. This form of allergy manifests as itchy, dry, scaly rash in areas of the skin exposed to perfume such as the face, neck and wrists. If you suspect skin sensitivity to perfume, one can apply perfume onto the clothes instead of the skin. Patch testing can also be done for accurate determination of the cause of the allergic contact dermatitis.

Please see a qualified Allergy & Immunology specialist for proper evaluation of your allergic diseases.

Below is a newspaper article in Bahasa Malaysia that talks about perfume allergy.

Rutin sembur haruman undang risiko alahan, lelah dan masalah kulit

SUDAH menjadi kelaziman Nadia menyembur minyak wangi setiap kali keluar rumah. Namun, bau wangi itu kerap menyebabkannya bersin sehinggakan selesema.

Tapi bagi eksekutif muda sepertinya, apalah sangat selesema berbanding rutin wajibnya menyembur pewangi berkenaan. Mana tidaknya, pewangi atau haruman sudah menjadi satu keperluan yang tidak dapat tidak, dielakkan.

Ada pewangi yang tidak diketahui kandungannya boleh membuatkan penghidap lelah ini berdepan masalah ‘serangan’ sesak nafas. Ada juga alahan luaran seperti kulit mengalami radang dan menjadi kemerah-merahan akibat tindak balas bahan tertentu dalam wangian yang digunakan. – Dr Kent Woo, Pakar Asma, Alahan dan Imunologi

Alasannya – Nadia berasa yakin untuk berhadapan atau berurusan dengan rakan sekerja, pelanggan mahu pun mereka di sekitarnya. Baginya, pewangi menjadi alat meningkatkan daya keyakinan diri biarpun terpaksa menahan selesema. Malah bukan Nadia seorang, sebaliknya ramai, termasuk remaja mempunyai penggantungan sedemikian terhadap wangian.

Apakah tepat tindakannya itu? Hakikatnya, sama ada disedari atau tidak, pewangi juga boleh membawa alahan sekiranya individu itu adalah penghidap asma, mereka yang mengalami masalah rhinitis dan alahan teruk.

Malah, mungkin ramai tidak ketahui ada pewangi menyebabkan kulit mengalami radang akibat alah dengan bahan kandungan dalam pewangi berkenaan.

Pakar Asma, Alahan dan Imunologi, Dr Kent Woo Chee Keen, berkata pewangi bukan perkara wajib untuk digunakan kerana jika individu prihatin mengenai kebersihan diri, tidak akan ada keperluan terhadap penggunaan wangian.
“Jika kita menjaga kebersihan diri dengan betul dan mandi mengikut kesesuaian, kita tidak perlu memakai wangian ketika menjalankan urusan seharian.

“Namun, kebanyakan daripada kita berasa lebih yakin sekiranya mengenakan pewangi sejurus sebelum meneruskan urusan harian dan ia boleh digunakan selagi tidak memudaratkan diri,” katanya yang berkhidmat di Hospital Gleneagles Kuala Lumpur.

Dr Woo yang ditemui baru-baru ini berkata, penggunaan minyak wangi atau wangian akan mencetuskan sensasi bauan terhadap deria hidu manusia dan ia mempengaruhi semangat seharian kala bekerja. Hal ini dikira positif kerana tidak mendatangkan kemudaratan kepada pemakai, namun jika individu menghidap asma, mereka mungkin alah kepada pewangi.

Bagaimanapun, tegasnya, jika individu berkenaan menghidap asma atau sensitif kepada alahan, mereka sewajarnya berhati-hati terhadap penggunaan wangian kerana ia dikhuatiri memburukkan keadaan asma yang dihidapi. Malangnya, tidak ramai yang mungkin menyedari risiko itu dan membiarkannya.

“Ada pewangi yang tidak diketahui kandungannya berupaya membuatkan penghidap asma atau lelah ini berdepan masalah ‘serangan’ sesak nafas kerana sebenarnya alah dengan bau atau pewangi yang disembur ke badan.

“Jika wangian berkenaan tidak sesuai dengan individu yang menghidap asma, dia boleh sesak nafas selepas beberapa minit menyembur pewangi ke badan. Namun jika tiada sebarang alahan, tiada kesan dialami.

“Perlu diingat, ia adalah alahan jenis dalaman kerana menyerang sistem pernafasan. Ada juga alahan luaran seperti kulit mengalami radang dan menjadi kemerah-merahan kerana tindak balas bahan tertentu dalam wangian yang digunakan,” katanya.

Memperincikan lagi, Dr Woo berkata, minyak wangi adalah campuran kompleks juzuk bauan asli dan tiruan. Lebih daripada 5,000 sebatian yang dikenali digunakan dalam pembuatan wangi dan ada sebatian tertentu tersejat dan menjadi bawaan udara menyebabkan ia berlegar-legar dalam udara.

“Jadi, jika ada individu bermasalah asma dan yang mempunyai masalah saluran pernafasan seperti alahan rinitis yang tidak dikawal, menyedut udara yang berbaur dengan wangian itu tadi, mereka akan mengalami bersin dan kesesakan hidung selepas terhidu bau itu.

“Dalam satu kajian yang diterbitkan jurnal perubatan pada 1995, sebanyak 36 peratus mengalami gangguan asma teruk, 17 peratus (sederhana) dan 8 peratus (sangat sederhana) dan gejala ini adalah disebabkan oleh kerengsaan saluran udara oleh wangian,” katanya.

Justeru, apakah yang harus dilakukan andai berdepan kemungkinan itu? Menurut Dr Woo, langkah segera perlu dilakukan seperti menemui doktor bagi mengesahkan sama ada anda sebenarnya mengalami alahan atau tidak terhadap wangian.

Alahan pada kulit akibat penggunaan haruman boleh diketahui dengan melakukan ujian tampalan pada bahagian belakang badan. Ujian itu dilakukan di hospital dengan pengendalian doktor.

“Doktor akan menampal sejenis bahan pada bahagian belakang anda. Tampalan berkenaan hanya boleh dibuka selepas 48 jam kerana kesannya akan dapat dilihat selepas tempoh berkenaan.

“Sistem imunisasi badan akan bertindak mengeluarkan tanda sekiranya anda alahan terhadap wangian seperti ada bintik merah, melecur dan radang kulit. Ada juga yang tidak akan menunjukkan sebarang tanda dan ia tidak bermakna anda tidak mengalami alahan,” katanya.

Bagaimanapun, katanya ada juga alahan yang tidak akan muncul walaupun selepas 48 jam, tapi ia mungkin akan muncul selepas beberapa hari atau selepas seminggu. Paling membimbangkan ialah alahan wangian yang berlaku pada bahagian wajah kerana ia mungkin akan menyebabkan muka bengkak, ada kesan terbakar mahupun kegatalan.

“Kadang kala ada juga alahan berlaku disebabkan oleh bahan makanan kerana ada bahan tertentu yang digunakan dalam masakan turut digunakan dalam pembuatan minyak wangi seperti kulit kayu manis, cengkih dan vanila.

“Jadi anda perlu berhati-hati kerana bahan dalam makanan ada juga yang sama dengan bahan di dalam minyak wangi. Dan alahan ini tidak semestinya disebabkan oleh minyak wangi saja, makanan yang diambil juga boleh menyebabkan alahan,” katanya.

Wanita paling banyak terdedah kepada bahan alahan di dalam wangian mahupun krim badan atau kelengkapan solekan yang digunakan pada wajah kerana ada antaranya mengandungi bahan kimia yang berbau wangi.

Bagi mengelak alahan, individu boleh membaca label pada wangian sebelum mengambil keputusan membeli atau menggunakannya pada badan bahkan krim badan juga mempunyai bahan wangian.

Wanita paling banyak terdedah kepada bahan alahan di dalam wangian mahupun krim badan atau kelengkapan solekan yang digunakan pada wajah kerana ada antaranya mengandungi bahan kimia berbau wangi.

“Cara terbaik menggunakan wangian ialah menyemburnya pada pakaian kerana ia tidak akan mengena kulit secara langsung. Jadi sekiranya kulit anda mengalami alahan, cara begini dapat mengelakkan alahan berlaku,” katanya.

“Pastikan anda membaca label pada sebarang alat penjagaan badan yang dibeli. Perkataan ‘unscented’ tidak bermakna bahawa ia adalah tiada bahan wangian sebaliknya pastikan ada tertulis ‘fragrance free’ kerana ia adalah bebas daripada sebarang bahan wangian,” katanya.

FAKTA: Antara tanda alahan pewangi

  • Bersin apabila tercium bau minyak wangi dalam masa beberapa minit, anda mula sakit kepala.
  • Pening selepas menggunakannya atau mencium bau wangian
  • Tangan menjadi ruam atau gatal selepas terkena cecair

Ujian alahan

  • Doktor akan menampal sejenis bahan pada bahagian belakang anda.
  • Tampalan berkenaan hanya boleh dibuka selepas 48 jam kerana kesannya akan dapat dilihat selepas tempoh itu.
  • Sistem imunisasi badan akan bertindak mengeluarkan tanda sekiranya anda alahan terhadap wangian seperti ada bintik merah, melecur dan radang kulit.
  • Ada juga tidak akan menunjukkan sebarang tanda.

Perfume Allergy

Perfume is a complex mixture of natural and synthetic sweet-smelling constituents. More than 5,000 compounds are known to be in used in the making of perfume. Certain compounds evaporate and become airborne thus lending perfume its smell.

Patients with allergic airway diseases can have exacerbations of their symptoms upon inhalation of these perfume compounds. For example, patients with allergic rhinitis that is not controlled can start sneezing and develop nasal congestion after smelling perfume. Patients with uncontrolled asthma may develop chest tightness and wheezing.

In a study published in the Annals of Allergy, asthmatic exacerbations after perfume challenge occurred in 36%, 17%, and 8% of patients with severe, moderate, and mild asthma, respectively. These symptoms were mainly assumed to be due to the irritant effects of perfumes.

However compounds found in perfumes can also cause allergic sensitization. The most common cause of cosmetic allergy is allergic contact dermatitis to the fragrance found in cosmetics. Recent estimates show that 1-4% of the general population are sensitized to ingredients of the fragrance mix.  Allergy to fragrance in cosmetics occurs predominantly in women with facial or neck eczema.  It can also present as itchy red patches where perfume are usually dabbed on, such as on the wrists or behind the ears.

Some patients with severe allergy to fragrance have been reported to develop to skin rash after eating spices such as cinnamon, cloves and vanilla which containing similar compounds found in fragrances. This is a situation where the person with allergic contact dermatitis to a compound has their rash exacerbated after eating certain cross reactive foods.

For patients who have allergies to perfume, they should also carefully read product labels. The use of the term unscented does not mean that it is fragrance free; they should instead choose a fragrance-free product which is typically free of allergenic fragrance.

Allergic Contact Dermatitis

Allergic contact dermatitis is a delayed type allergic reaction on the skin after contact to a specific allergen. For allergic contact dermatitis to occur, the skin must first come into contact with the offending agent and sensitization to occur. At first, the area might sting or burn, but then later itch is the major problem. The dermatitis rash might appear as itchy bumps, dry and scaly skin, or thickened darker colored skin.

 A qualified Allergy and Immunology specialist can perform patch testing for difficult cases. A patch test will enable the identification of the offending agent. Avoidance of contact with the offending agent is the key to success in allergic contact dermatitis treatment.

Keratosis Pilaris

Keratosis pilaris is a genetic disorder of the skin. It is a common skin condition where the skin on the back and outer sides of the upper arms are rough and bumpy. This condition is also described as chicken skin or goose bumps. The common areas of the body that are affected are the outer-upper arms and thighs.

Although no clear cause has been found, keratosis pilaris is often described in association with other dry skin conditions and also with asthma and allergies. It affects nearly 50-80% of all adolescents and approximately 40% of adults. In general, the condition is frequently cosmetically displeasing but medically harmless.

Overall, keratosis pilaris is self-limited and tends to improve with age in many patients. Some patients have lifelong keratosis pilaris with periods of remissions and exacerbations.

Treatment

Because keratosis pilaris is a genetic disorder, no cure is possible. However with appropriate care, the skin condition can be improved. As a general rule, treatment needs to be continuous to maintain improvement and if you stop, the condition returns.

  • General measures to prevent excessive skin dryness, such as using mild soap-less cleansers are recommended, and lubrication is the mainstay of treatment.
  • Topical exfoliants. Medicated creams containing alpha-hydroxy, lactic or salicylic acid or urea moisturize and soften dry skin while helping to loosen and remove dead skin cells.
  • Topical steroids. Low potency corticosteroids can reduce cell turn over and improve the skin condition. However, corticosteroid creams are not recommended for long term use.

In general, Keratosis Pilaris is often diagnosed and managed by dermatologists. However, since this condition is sometimes associated with allergic diseases; if you have allergies please see a qualified Allergy & Immunology specialist to evaluate your allergies.
