Cracks in the corner of the mouth are a common and irritating problem — not a month goes by without a patient asking me for e are several potential causes for the condition — known as angular stomatitis — and it’s important to identify the right one to ensure treatment works. The treatment your doctor prescribed, Fucidin, is an antibiotic, and would almost certainly have cured the cracks by now if a bacterial infection was to blame.
秋冬气候干燥，身边有不少人会出现嘴角干裂的情况，而较为通常的处理方式便是涂抹凡士林霜，但很多情况下却难以达到治标又治本的效果。据相关方面的医生透露，嘴角开裂是一种相当常见而又恼人的情况，而导致的原因则有很多，其中之一便是口角炎，而查准病因，并且对症下药，这对非常重要。凡士林霜是一种抗生素，对于由细菌感染引起的开裂是可以治愈的，若发现时候使用之后效果不明显，或许致病另有原因。
The spores of this yeast are everywhere, and given a chance — if you have been a bit tired or run down for some reason — it can gain a hold and cause angular stomatitis.
其中，一种可能性是真菌感染也会导致嘴角开裂，常见的情况多为白色念珠菌，此类真菌的存在普遍，一旦当人体免疫力下降，它便“乘虚而入”引发口角炎。这样的情况下可以使用凯妮汀这样的抗真菌药物，用指尖蘸取少许涂抹，每日三到四次，持续两个礼拜左右，便可治愈，而这类药物无需处方便可购买到。
I suggest you buy a tube of either Canesten or Daktarin cream (they’re both antifungals) and apply it with the tip of a finger, sparingly, three to four times daily for a fortnight; this may well result in a cure. These products can be bought over the counter so you will not need a prescription.
Another possibility (although this is far less common) is a vitamin B deficiency, if the cracks are accompanied by a sore is most likely if you’ve not been eating enough fruit, vegetables and wholegrain foods — all good sources of Vitamin if the antifungal treatment also fails, buy some B complex vitamins — a mix of several forms of Vitamin B — from the chemist and take as the label directs for a month or two.
而另一种引发的原因便是维生素B缺乏症，嘴角开裂的同时伴随有口疮舌疮的情况。这可能因为饮食不均衡造成的，而水果、蔬菜、全麦食品中都富含维B。因此，在抗真菌药物药效不明显时，可以配合服用一些维生素B。
If neither of my suggestions is helpful, ask your doctor to take a blood test to check for anaemia. Iron deficiency anaemia and vitamin B12 anaemia are possibilities — both of which may be due to an underlying disease. Iron deficiency anaemia has many causes — it might simply be you are not getting enough iron from your food. But it can also be an indication of blood loss in the intestine from a silent ulcer or hiatus hernia. Other problems in the intestine such as diverticulosis (where small bulges or ‘pockets’ form in the wall of the large intestine) can cause small but continued blood icious anaemia, due to inadequate amounts of Vitamin B12 in the system, only has one main cause: the inability to absorb the happens when the stomach lining no longer produces the ‘intrinsic factor’, a molecule that combines with B12 to absorb it into the body. Failure to make the intrinsic factor is usually caused by the immune system attacking the cells that secrete it. Both iron deficiency and pernicious anaemia require further investigation, which is why it’s important to seek advice if the angular stomatitis doesn’t resolve with the simple measures I have you suspect this is the case, see your dentist before asking your GP to investigate the matter.
若均不是以上两种情况的话，医生会建议病人进行血液测试，检查是否有贫血的情况，缺铁性贫血和B12缺乏性贫血的表现也包括了嘴角干裂。缺铁性贫血的原因或是因为未从食物中获取足够的铁元素，也或是因为由于溃疡所引起的。而由于缺乏B12所导致的恶性贫血则是因为无法再吸收这一维生素所导致。所以当出现嘴角干裂久治不愈时，就应该进行血液检查。
