Japanese: 鵞口瘡 - がこうそう(英語表記)Thrush

What is the disease?

Infection of the oral cavity with a fungus called Candida albicans causes white spots ( White moss ( Pact ) ) is a disease of infancy.

What is the cause?

Candida albicans enters the baby's mouth and causes an infection.

During newborn life, infection occurs through the birth canal, and during infancy, infection occurs from hands, nipples, or baby bottles that have Candida on them during breastfeeding.

It rarely occurs after early childhood.

How symptoms manifest

White spots similar to milk cakes are formed on the oral mucosa, tongue, and palate. Milk cakes can be easily removed by rubbing, but thrush is difficult to remove even by rubbing, and if you try to remove it by force, it will bleed. Most cases are asymptomatic, but sometimes the amount of milk consumed may decrease due to pain.

If candida from the mouth is swallowed and excreted in the stool, it can lead to a diaper rash caused by candida.

Testing and diagnosis

The diagnosis is made by visual inspection and by whether the white spots are difficult to remove even by rubbing. Potassium hydroxide is dripped onto the sampled white spots and Candida is confirmed by observing them under a microscope.

Treatment methods

Since the condition is often mild and asymptomatic, it is monitored without treatment.

If the area is large or the pain from the erosion affects breastfeeding, apply Fungizone syrup 3 to 4 times a day. It usually heals within a few days, but it may recur.

If your baby has thrush, you should be careful to keep your hands and nipples clean and disinfect feeding bottles.

What to do if you notice an illness

If you have milk residue-like particles in your mouth that are difficult to remove, seek medical help.

どんな病気か

 カンジダアルビカンスというカビによる口腔内の感染により、口のなかに白い斑点のような塊(白苔(はくたい))が付着する乳児期の病気です。

原因は何か

 カンジダアルビカンスが乳児の口に入り、感染します。

 新生時期は産道からの感染で、乳児期には、哺乳時にカンジダの付着した手指や乳頭、哺乳びんから感染します。

 幼児期以降ではほとんど起こりません。

症状の現れ方

 口腔粘膜、舌、口蓋に白い斑点のようなミルクかすに似た塊が付着します。ミルクかすの場合はこするとすぐに取れますが、鵞口瘡の場合はこすってもなかなか取れず、無理に取ると出血します。ほとんどが無症状ですが、たまに痛みのために哺乳量が減ることがあります。

 口腔内のカンジダを飲み込み、便中に出ることで、カンジダによるおむつかぶれを合併することもあります。

検査と診断

 視診と、こすっても取れにくいということで診断します。採取した白斑に水酸化カリをたらし、顕微鏡でカンジダを観察することで確認します。

治療の方法

 軽症で無症状のことが多いため、治療せずに経過観察します。

 範囲が広かったりびらんによる痛みのため哺乳に影響する場合は、ファンギゾンシロップを1日3~4回塗ります。通常、数日で治りますが、繰り返す場合もあります。

 鵞口瘡になったら、手指や乳頭の清潔や、哺乳びんの消毒に注意が必要です。

病気に気づいたらどうする

 口のなかに取れにくいミルクかすのようなものがあったら、医療機関を受診してください。
