突然失去嗅覺,與染上新冠狀病毒Covid-19有關?

有病人最近突然失去嗅覺,為此感到恐慌?因為在社交媒體上,他讀到有關染上新冠狀病毒Covid-19患者失去嗅覺的報導。由於新冠肺炎疫情仍在全球肆虐,病人擔心自己突然失去嗅覺與新冠狀病毒Covid-19有關,看來也不無道理。

不過,請不要這麼快就下結論!在美國,確實有越來越多關於Covid-19病人失去嗅覺的報導,但事情的真相如何,科學家們還不完全確定兩者之間是否存在關聯。以下是專家們的不同意見:

 

專家們的不同意見

美國耳鼻咽喉及頭頸外科醫學會建議,可以使用嗅覺檢查篩查新的Covid-19病例。該建議的依據是有報導指出沒有明顯症狀的Covid-19患者,他們的嗅覺有明顯下降或完全喪失的情況。

但是,其他醫學專家卻持有不同意見。例如,世界衛生組織(WHO)和美國疾病控制與預防中心(CDC)則表示,單純喪失嗅覺並不足以表明是感染Covid-19新冠狀病毒的明確診斷指標。

 

 

多種病毒感染可致嗅覺喪失

研究顯示,多達40%的普通感冒和流感患者,以及其他病毒感染者,都會出現暫時性的嗅覺下降或喪失。患有過敏症的人亦有此情況,他們主要是流鼻水和鼻腔不斷受刺激繼而影響到嗅覺,但嗅覺通常可在幾星期內復原。

另外,嚴重的頭部外傷,鼻息肉和神經退行性疾​​病,同樣可令嗅覺下降或喪失,這樣的情況在老年人當中更為常見。事實上,全球約有3%至20%的人患有不同程度的嗅覺障礙。

科研人員指出,由於Covid-19是新型病毒,此刻斷言喪失嗅覺是新冠狀病毒的症狀仍言之尚早。原因之一,是這種聯繫是基於若干的報告,而不是長期的科學研究。

不過,有研究人員在英國做了一項研究,他們使用一個應用程序收集了來自579名患者的Covid-19症狀數據。他們得出的結論是:將近60%的被調查患者報告稱失去了嗅覺和味覺。另在1,123名冠狀病毒檢測呈陰性的人中,約有18%的人也報告了同樣失去了嗅覺和味覺!

 

對於這些不同的意見,人們仍感到困惑,儘管我們都對新冠狀病毒在全球擴散感到擔憂,但我們應該保持冷靜,並在需要時尋求專業診治。如果你突然失去嗅覺,不要糊亂猜測,只有你的耳鼻喉醫生診斷後才能給出明確的答案。

Dealing with Allergies in the Time of the Coronavirus

It’s quite unfortunate that allergy season is already in full swing at the same time as Covid-19 continues to take lives.  Many people who experience allergies at this time of the year may be more anxious about their symptoms for this reason.

 

Are you one of them or you know somebody in these shoes? Your anxiety is justified, in a way, because allergies can have an impact on the overall health of your respiratory system. You may even be at greater risk of getting the coronavirus because your respiratory system is more fragile.

 

But before you succumb to panic, here are a few things that you should know to keep your wits about you.

 

Keep Your Lungs Healthy From the Start

If you have had allergy attacks at this time of the year before, then you will likely still get them in 2020. You should then start taking precautionary measures now so that your lungs will be remain healthy. You can talk to your ENT doctor about starting early on your medications, perhaps changing them to account for the new threat.

 

The earlier you start on your anti-allergy medications, the less likely you will experience the symptoms. Your body’s immune system isn’t sent into overdrive fighting the inflammation caused by allergens and, thus, it has less mucus production. The common medications include nasal steroids and antihistamines, which are prescribed as a way to control the symptoms of an allergy attack.

 

Of course, you should minimize your exposure to the allergens that trigger your symptoms. Since this is the time of Covid-19, you have to adopt the preventive measures recommended by WHO and other medical experts. These include practicing good hygiene including washing your hands frequently and social distancing.

 

Keep Calm and Carry On

Unless you have been exposed to people carrying the coronavirus or people diagnosed with Covid-19, you have to keep calm if your allergy symptoms seem to have returned. You may or may not have the coronavirus but it’s important to keep calm, seek testing and medical treatment, if needed, and protect others.

 

There are also cases when an allergy attack happens for the first time in adults. Again, don’t panic as it’s actually common for adults who have never experienced allergies to have them in later life. The adult-onset allergies may likely be due to higher levels of pollution and declining immune system function.

 

The bottom line: There may be no effective vaccine and treatments yet for Covid-19 but there are treatments that will address your allergies. Get control on what you can and let the medical experts find the solution to the current pandemic.

Turn Off the Post-nasal Drip With These Effective Methods

The mucus running down your nose isn’t just inconvenient since it requires constant wiping, but it can also be embarrassing. Plus, it’s another symptom of a cold, or allergies or flu that makes your life less happy, perhaps even add to your anxiety about a more serious illness.

 

You may have to see your ENT doctor for a medical evaluation in case your post-nasal drip symptoms aren’t resolved in a few days. But in the meantime, you may want to adopt these easy yet effective methods to turn off the tap, so to speak.

 

 

Limit Your Allergen Exposure

Allergies are among the more common causes of post-nasal drip. If you have post-nasal drip and a feeling of itchiness, then you’re likely having an allergy attack. This is because the allergy cells in your body release histamine that, in turn, causes itchiness.

 

  • Use HEPA filters and dust mite covers in your home. These will decrease your exposure to allergens floating in the air and on your upholstered furniture including your mattress.
  • Wash your bed linens in hot water as frequently as possible.
  • Keep your pets outdoors since their hair and dead skin cells can cause allergies.
  • Get rid of items in your house that can collect dust, such as carpets and rugs, even old books and magazines.

 

 

Watch What You Eat

Gastrointestinal reflux disorder (GERD) can cause post-nasal drip and can be triggered by eating fried and fatty food as well as chocolate, alcohol, coffee, soda and citrus fruits. If your post-nasal drip occurs after eating these food, then you may have to limit, if not stop, eating them.

 

You should also consider eating smaller yet more frequent meals, as well as eating more whole grains, lean meats and ginger. You will be healthier for it, too!

 

You may also benefit from reducing your intake of dairy products. These include cheese, milk and yogurt, although you can still enjoy them in limited amounts.

 

 

Rinse Your Sinuses

This works because it removes the allergens and irritants lodged in your nasal passages. The less irritants, the less irritation and the less drip since your body doesn’t have to produce as much mucus to get rid of them.

 

Rinsing your sinuses is as easy as pie, too! You can either use a homemade rinse or buy pre-packaged saline solutions. For a DIY solution, you can use distilled water, boiled water that has been cooled afterwards, or filtered tap water.

 

Steaming is also an effective way to rinse out your nasal passages and loosen mucus from your throat. You can fill a pail or large bowl of hot water, add two drops of eucalyptus oil, and place a towel over your head while inhaling the steam. You can do this for 10 minutes at a time, 2-3 times a day.

 

Your ENT doctor can also recommend medications but these tips will improve your condition, too. Think of it as a wholistic approach to becoming better sans the post-nasal drip.

Lost Your Sense of Smell? It May Not Be Coronavirus!

Do you feel like you’ve suddenly lost your sense of smell and you’re now panicking? Perhaps you think that it’s the coronavirus because you’ve read reports on social media about Covid-19 patients losing their sense of smell. Perhaps you believe that you now have Covid-19, thus, the panic.

 

But don’t jump into conclusions! While there are, indeed, an increasing number of reports about Covid-19 patients losing their sense of smell, known as anosmia, these are just anecdotal evidence. Scientists aren’t sure yet whether there’s a connection between anosmia and Covid-19.

 

 

Contrasting Opinions from the Experts

The American Academy of Otolaryngology-Head and Neck Surgery suggested that anosmia can be used for screening new Covid-19 cases. It based its suggestion on reports that Covid-19 patients didn’t have noticeable symptoms but their sense of smell was either significantly reduced or completely lost.

 

But there are opinions to the contrary from other medical experts. The World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC), for instance, haven’t added anosmia to their Covid-19 list of symptoms. These organizations also said that the simple loss of smell isn’t sufficient reason to make a definitive diagnosis of coronavirus.

 

 

Common in Viral Infections

It should be noted that in numerous studies, up to 40% of people with the common cold and flu, among other viral infections, experience temporary anosmia. This is also the case among people with allergies, partly because of the runny nose.  But it’s usually resolved within a couple of weeks or so.

 

About 3% to 20% of the general population are known to experience prolonged smell disorders. These disorders are more common among older people because of underlying medical conditions and history. These include severe head trauma, nasal polyps and neurodegenerative diseases.

 

But it’s too early to tell whether anosmia is, indeed, a Covid-19 symptom. One of the reasons is that the connection is based on anecdotal reports instead of scientific studies conducted over the long-term period. There’s also the matter of people confusing the loss of the sense of smell and taste since these are closely intertwined.

 

A British study was conducted wherein the researchers used an online app to collect data on Covid-19 symptoms from 579 patients. Their conclusion: Nearly 60% of the surveyed patients reported losing their sense of smell and taste. But about 18% of 1,123 people who tested negative for the coronavirus also reported the same loss!

 

The bottom line: While we are all concerned about the spread of the coronavirus in the United States and the world, we should keep calm and seek medical attention, when needed. If you lost your sense of smell, it may or may not be a cause for concern and only your ENT doctor can give a definite answer.

 

Seek medical attention if it continues to be bothersome to you or your family members. Otherwise, you may want to stay home and follow the shelter-in-place order, especially if you don’t have fever, dry cough and shortness of breath.

Who’s Likely to Get Throat Cancer?

Throat cancer is a scary ENT disease, not only because it’s the Big C but also because it can take away the capacity to speak! Take note that it occurs in the pharynx (throat) as well as in the larynx (voice box) or in the tonsils, all of which are important in the generation of sound.

 

Some people have higher risk for getting throat cancer. Let’s take a look at these risk factors as well as the symptoms of this ENT disease to look out for.

 

 

Risk Factors

Keep in mind that belonging to one or more of these risk factors doesn’t automatically mean that you will get cancer, 100%. Instead, these factors will increase your risk of getting the Big C because of the accumulated damage inflicted on the throat.

 

  • The use of tobacco products including chewing and smoking tobacco because it has nicotine and other substances that compromise the health of the tissues in the throat.
  • The excessive use of alcohol because of its adverse effects on the body, especially over a prolonged period.
  • The presence of the human papillomavirus (HPV), a sexually transmitted disease, has also been shown to increase the risk of throat cancer.
  • The untreated diagnosis of gastroesophageal reflux disease (GERD) has also been shown as a risk factor in throat cancer.

 

Surprisingly, a diet with insufficient amounts of fruits and vegetables can also increase the risk of throat cancer! But this may not be surprising considering that a healthy body and, thus, a healthy immune system may decrease the risk of getting any type of cancer.

 

 

Signs and Symptoms

The specific location where the malignant growth occurs largely determines the symptoms that can be experienced. There’s also the matter of lumps in the neck or throat being an indication of an upper respiratory infection. The lumps may be caused by enlarged lymph nodes fighting off the infection, such as strep throat, followed by their return to their normal size once the infection clears.

 

But if a lump persists without the presence of an infection or even after the infection has been treated may be a warning sign of cancer.  The lump may or may not be accompanied by a thickness or swelling in the neck.

 

If you have the following symptoms along with a lump in your neck, then you should seek your doctor’s opinion. Early diagnosis and treatment is key in successfully overcoming throat cancer.

  • Difficulty in swallowing that persists for a few weeks without reasonable cause
  • Vocal changes like hoarseness
  • Feeling of food being lodged in the throat even after swallowing
  • Persistent sore throat
  • Mouth sores that either doesn’t heal with medication or easily bleeds
  • Red- and white-colored patches on the tongue, inside of cheek and/or gums
  • Feeling of numbness in the mouth or tongue
  • Chronic nasal congestion
  • Pain in the ears

 

Your ENT doctor will perform a series of diagnostic tests to determine the underlying cause of your symptoms. Keep calm, nonetheless, as throat cancer has several effective treatment protocols when administered properly and promptly.

 

Since ENT problem is quite different from case to case, it is suggested to consult an ENT doctor for the appropriate ENT services and treatment.

面癱 – 如何治療?面容能夠復原嗎?

面癱如何治療?能夠完全復原嗎?

若能及早醫治,有80%的面癱患者,能夠獲致理想的治療效果。在治療方面,如果病因由神經線受感染導致,醫生處方類固醇及維他命補充劑等藥物,約在3-4星期內會恢復神經功能。如果面癱是中耳炎、腮腺腫瘤、面部神經線腫瘤等誘發,就必須從根源着手醫治。對於由狀疱疹病毒所引起,面神經麻痺的痊癒成效則稍遜。面癱影響患者語言功能,病人需要接受言語治療,來重新掌握面部肌肉及神經的協調,此舉可將面癱造成的影響減低。對於那些復元成效不佳的病人,則需要透過物理治療或外科手術矯正變形的容貌,改善面癱的影響。

 

 

面癱會有什麼後遺症?

 

表情不自然

面癱雖不無性命之憂,但部分病人在治療和休養後,依然無法完全恢復,在面容上仍留有不良影響,比如皺眉、蹙額、眨眼、微笑、說話時面部肌肉不聽使喚不協調,總不能回復從前的自然狀態。患者味覺和淚線亦可能受損,部分人康復後會留有後遺症,如大笑時眼角跳動、味覺減退、無故流淚。

 

影響視力

患病期間由於眼皮不能自如閉合,眼睛容易乾澀,有人因而出現角膜炎,嚴重時甚致會影響視力。因此在治療面癱期間,保護眼睛十分重要。如果病人眼皮不能閉合,醫生或會考慮為病人進行眼皮植入手術,目的是讓眼皮可以閉合,避免眼角膜受傷,累及視力。

 

情緒問題

面癱除影響面部的運動神經,也影響部分味覺神經、淚腺神經,所以未能完全復原的病人,會出現漏口、流口水、味覺遲鈍。有的病人甚致有面容不對稱,這些後遺症實際影響顏面功能和動作,面容受損也造成強大的心理壓力,影響病人社交活動,病人或會出現情緒問題,此時病者和其家人必須正視,尋求進一步的治療和輔導。

 

 

面癱有預防方法嗎?

面癱沒有什麼預防方法,任何人都有機會遇上,若不幸遇上,我們仍然可以做些事來促進復康:

  • 接受物理治療有助促進顏面神經盡快復原。
  • 按治療師指示做一些面部特殊表情的練習,讓肌肉重新學習。
  • 按摩面部肌肉,使肌肉保持彈性和柔韌度,讓肌肉練習收放。
  • 睡覺時或外出時,為未能閉合的眼睛蓋上紗布。
  • 盡量保持身體健康,減少患上流感的機會,因為流感病毒有可能引起面部神經發炎而導致面癱。

 

 

面癱是面部神經受傷或感染等問題引致,不及早治療可造成神經功能永久障礙。若你出現面癱情況,請不遲疑,立即聯絡香港耳鼻喉專科,電話: 3100 0555。由我們的耳鼻喉科醫生為你診治。

中耳炎可誘發面癱,面癱是什麼?有何症狀?

一覺醒來,發現自己半邊面動不得,嘴歪,口水從嘴角不受控地流出,眼皮不能自如閉合,但手腳看來卻沒有問題,驚慌之下人不禁會想到中風。

 

 

排除中風,突然出現以上情况可能是面癱,所謂面癱即是主司面部表情的神經麻痺,令面部肌肉癱瘓,各個原本協調精細的感官喪失功能。患者就會出現上述提及面部麻痺、嘴歪、流口水、口齒不清等情況。面神經不單主管我們的面部表情,還有淚腺和唾液腺及部份味覺神經。一旦受傷或病毒感染引致損傷,便會造成神經功能的種種功能障礙。

 

 

面癱是什麼?面癱的成因又是什麼?

面癱主要是病毒感染引發,病人通常是一邊面出事,另一邊面卻無任何症狀,醫生稱之為急性單側面神經麻痺,醫學名稱是《貝爾氏面神經麻痺》。研究發現,貝爾氏面神經麻痺與單純性疱疹第一型病毒有密切關係。另外,帶狀疱疹病毒也是引發面癱的常見成因,由帶狀疱疹病毒引發的面癱稱為《侖謝亨特氏症候群》。其他成因也包括顏面創傷、急性中耳炎慢性中耳炎引發膽脂瘤、腦部或面部神經腺瘤、某些遺傳性神經失調疾病同樣可以引發面癱。

 

 

面癱屬罕見疾病嗎?

事實上,面癱並不是罕見疾病,國外研究顯示,每五千人便有一病例,香港雖然沒有實質數據,但不少名人歌星演員都曾患上面癱並被廣為報導。從患病人士看出,此病不論年齡性別,任何人士都有機會得病,特別在流感暴發的季節。

面癱成因雖未能完全知曉,但免疫力低的人士較易受過濾性病毒入侵,令神經線發炎及管道阻塞,出現神經癱瘓或受損。因此強健身體,流感大流行的季節要特別留意保重身體,避免流感感染。

 

 

面癱有什麼症狀?

由於病毒侵襲控制和協調面部的神經,造成面神經發炎麻痺,面部肌肉無力彊硬,原本輕而易舉的皺眉、蹙額、眨眼、微笑等表情,現在全部做不到。患者臉孔明顯不對稱甚致變形,令容貌受損。面神經亦控制味覺、淚腺及口水的分泌,發生面癱時,眼睛會乾澀、舌頭麻木,味覺減退、飲水水由口角流出、言語不清,吞嚥困難、耳後乳突疼痛等,面癱的症狀和影響絕對不少。

 

那麼,面癱如何治療?能夠完全復原嗎?下篇文章我們會談談這問題。

 

 

如你發現自己有上述的症狀,請不再遲疑,立即聯絡香港耳鼻喉專科,電話: 3100 0555。由我們的耳鼻喉科醫生為你診治。

外耳炎 – 如何治療和預防外耳炎?

耳痛是眾多耳疾的或面部疾病的常有症狀,醫生如何判斷患者耳痛成因是外耳炎導致呢?

 

外耳炎如何判斷?

耳鼻喉專科醫生根據病人的症狀、檢查、或細菌培植來判斷。外耳炎常見的症狀包括下列4點:

  1. 耳部的不適是在過去數天內發生,但後來可以在48小時內迅速發病。
  2. 出現嚴重的耳痛、耳朵痕癢、或耳道有悶塞感等外耳道發炎的症狀。
  3. 耳鼻喉醫生檢查病人耳部時,病人的耳殼或耳珠疼痛、外耳道腫脹、發紅、有分泌物、耳膜發紅、耳部附近出現蜂窩性組織炎,甚至頸部出現淋巴結發炎等症狀。
  4. 正常的外耳道,醫生可以由外耳道直接看見耳膜,但外耳道因發炎腫脹,檢查時也很難看見耳膜。

 

 

外耳炎如何治療?

  • 耳鼻喉醫生會為患者清除外耳道內積存的耳垢和分泌物,使用滴耳藥水、抗組織胺等藥物為患者止癢和止痛。
  • 若是嚴重發炎,醫生會處方抗生素,控制耳道內的細菌擴散,令耳道盡快消炎。
  • 得到適當的治療後,一般2-3日病情就會有改善,大約一星期可痊癒。若然治療沒見成效,醫生會考慮拿病人的分泌物拿去做細菌培植,再配對有效的抗生素治療。
  • 治療期間,病人必須應保持外耳道乾燥,小心污水入耳,以防復發。

 

 

如何預防外耳炎?

  • 適量運動,良好生活作息,身體健康免疫力強是最好預防外耳炎方法。
  • 注意個人衛生和習慣,避免用硬物或手指挖耳,因這樣做容易弄傷耳道皮膚,引致細菌感染。
  • 保持外耳道清潔乾爽,沐浴或洗頭時,小心防污水走入耳道。如不慎耳朵入水,不要用棉花伸入耳朵吸水,可以側頭及把耳廓拉後向上後方,讓水自然流出。
  • 如果曾經患上外耳炎,為防復發,暫停游水。沐浴或洗頭亦要小心耳朵入水造成再次感染。
  • 佩戴耳道式助聽器人士,助聽器在使用後應用乾布抹淨及放在乾爽的盒子。助聽器的耳塞要定期消毒或更換,這有助耳道保持乾爽,減低耳道悶濕環境,防止細菌滋生,引發外耳炎。
  • 喂哺中的嬰兒,父母要留意喂奶的姿勢,盡量避免讓嬰幼兒躺著喝奶,以免嬰兒嘔奶時,奶液流入耳內引起發炎。
  • 耳道有自我清潔的能力,不要挖耳或過度地去清潔耳道,因過度清潔耳道返而容易令耳道感染。

 

 

外耳炎發展可以十分迅速,如突然耳痛,耳朵痕癢,症狀持續並趨嚴重,請不再遲疑,立即聯絡香港耳鼻喉專科,電話: 3100 0555。由我們的耳鼻喉科醫生為你診治。
