SALIVARY GLAND CANCER

SALIVARY GLAND CANCER

There are 3 major salivary glands on each side of our face which make saliva which is important for our oral health. Saliva contains enzymes which help in the process of digesting food as well as antibodies to prevent infections of the mouth. It also helps to lubricate our mouth and throat to allows us to swallow dry or hard foods easily and prevent sore or dry throat after talking too much.

The salivary glands are:

  • The parotid gland is the largest salivary gland and is situated just in front of the ear and accounts for around 70% of all salivary cancers
  • The sub-mandibular gland is smaller and is situated just below the jaw.
  • The sublingual gland is the smallest and is situated under the floor of the mouth and below either side of the tongue.

Symptoms & Signs of Salivary Gland Cancer

  • Mass or Swelling at the neck region
  • Difficulty opening mouth or swallowing
  • Change in voice
  • Numbness or weakness in the face
  • Pain on one side of the face

RECOMMENDED VACCINES WHEN YOU TRAVEL TO AFRICA

RECOMMENDED VACCINES WHEN YOU TRAVEL TO AFRICA

Recommended Vaccines When You Travel to Africa

1) Hepatitis A 

Risk increases with duration of travel and is highest for those who live in or visit rural settings, trek in back-country areas, or frequently eat or drink in areas with poor sanitation.

2) Meningococcal Disease

Risk is increased for travellers to sub-Saharan Africa (the ‘meningitis belt’) during the dry season, especially if there is prolonged contact with locals.

3) Typhoid Fever

Risk is higher where environmental sanitation and personal hygiene may be poor. The adventurous eater venturing “off the beaten track” should also consider vaccination.

4) Rabies

Should be considered in most parts of the world if exposure to animals is expected. Travellers spending time outdoors, especially rural areas, and who are involved in outdoor activities (eg cycling, camping, hiking outdoor work, caving) are at particular risk. Children are also considered higher risk because they tend to play with animals and may not report bites.

5) Yellow Fever

Recommendations may vary by country.

Proof of vaccination (International Certificate of Vaccination) against yellow fever may be required or travel to and from some of the countries in South America and Trinidad and Tobago.

Some countries with endemic yellow fever may waive requirements for travellers coming from non-infected areas and staying less than 2 weeks. Vaccination is recommended for travel in countries that lie in yellow fever endemic zones but do not officially report the disease.

Note: This is a guide only. Advice by your healthcare professional will vary depending on destination, duration of travel, types of accommodation and what types of activities you take part in.

VARICOSE VEINS: WHAT IS IT?

VARICOSE VEINS: WHAT IS IT?

Arteries are blood vessels which transport blood from the heart to our organs which veins transport blood from the organs back to the heart. Blood is prevented from flowing backwards by tiny valves along the veins which open and close to let blood through in one direction, namely back towards the heart. The veins of the lower limbs can be either superficial (just under the skin) and deep (under the muscle).

Varicose veins are swollen and enlarged superficial veins which develop when these small valves are damaged or don’t work properly.

Risk Factors

Factors which can increase your chances of developing varicose veins include:

  • female
  • older age
  • overweight
  • pregnancy
  • abdominal mass such as fibroids
  • having a job that involves long periods of standing

Symptoms and stages of varicose veins

Symptoms of varicose veins include pain which is usually described as heaviness or aching pain leg swelling, itchiness and dark pigmentation of the skin. Severe cases of varicose veins can lead to skin ulcer formation which are slow to heal. Complications include bleeding, deep vein thrombosis (DVT), thrombophlebitis (painful inflammation of the veins) and varicose eczema.

When do you need to see a doctor?

Do not wait until the varicose veins become so bad that it becomes difficult to treat. The earlier it gets treated, the higher the chances of a good outcome. It should be treated when there are symptoms such as itching, bleeding or swelling.

WHY AM I NOT GETTING PREGNANT AGAIN?

WHY AM I NOT GETTING PREGNANT AGAIN?

Mrs M walked into the clinic with her beautiful daughter Maya, aged 5. She is a happily married woman and conceived Maya within their first 6 months of marriage. Her pregnancy was well and Maya was delivered via a caesarean delivery.

The obvious question popped up in my mind, “How can I help you?”

“Well one ain’t enough and we have been trying for a second child for the past one and a half years. I just don’t understand why i am not getting pregnant. I got pregnant with Maya easily. Surely we are not suffering from infertility. But why it is not happening again?”

She is just one out of many women who find it difficult to believe that they are struggling for a second child or what is medically known as secondary sub-fertility.

What leads to secondary sub-fertility? Let’s find out why.

1) Age factor

In a natural pregnancy, age is an important determinant of success rate. This is mainly because a woman’s egg number and egg quality declines with age. Generally, a woman’s fertility start to decline rapidly after the age of 35-37 years old compared to when they were younger. At a younger age, fertility declines more slowly.

This is the reason why doctors (and your mother and mother in-law too!) will advise you to compete your family earlier than later. Thus, your chances to conceive for the second time is not similar to when your had your first child.

2) Ovarian reserve (egg numbers)

A woman’s age do play a crucial role in her ovarian reserve. Ovarian reserve means the number of eggs that you are left with, which correlates with your chances to get pregnant. The lower the ovarian reserve, the lower your chances to get pregnant.

Besides age, there are other factors which can decrease your ovarian reserve.

Ovarian surgery (for ovarian cyst) and endometriosis can decrease your egg numbers. If you have previous surgery to your ovary and find it difficult to conceive again, maybe it’s time to see your doctor.

3) Ovulation Problem

Ovulation is crucial for a natural conception. When ovulation is irregular, it increases your difficulty to get pregnant naturally simply because you can not time your ‘fertile’ window accurately.

But why ovulation become irregular now and not before when you conceived your first child?

Your weight has an effect on your ovulation. If you have put on weight after your first child, it can affect your ovulation and your monthly period cycles.

For some who have been diagnosed with Polycystic Ovarian Syndrome (PCOS), period irregularity may start later in life. In PCOS, the woman is not ovulating regularly.

In this situation, once all the other causes are excluded, the simplest thing to do is to make the ovulation regular. In most cases, weight reduction together with some fertility medication is sufficient.

4) Tubal factor

Women have a pair of Fallopian tubes attached to the womb. This tube picks up the ovulated egg and fertilisation of the egg by the sperm happens in the tube.

If the tubes are damaged or blocked, chances to get pregnant naturally is much reduced or impossible (in the case of bilateral blocked tubes).

Fallopian tubes are at risk of being damaged or blocked when a woman undergoes any kind of pelvic surgery including a caesarean section, ovarian cyst removal or removal of a uterine fibroid.

Pelvic infections (such as Chlamydia) can also lead to tubal blockage. Thus, a woman with these risk factors should check the patency of their tubes.

5) Endometriosis

Endometriosis is not an uncommon cause of secondary subfertility. Endometriosis can lead to ovarian cyst, which can have a direct negative effect on egg numbers.

Endometriosis can also lead to tubal blockage due to continuos process of bleeding and scar formation.

While there is no magic treatment that can eliminate endometriosis completely, if diagnosed early, it can be controlled while in some cases, fertility treatment offered before the condition worsens.

6) Uterine factor

The womb or the uterus, is rarely the cause of subfertility. If you had successfully delivered a child before, it means that your uterus is able to carry a pregnancy.

However, after a major uterine surgery such as removal of numerous uterine fibroids, the anatomy of the uterus can be distorted and the lining of the uterus where the pregnancy implants can be damaged.

Another common uterine factor is a gynaecological condition called adenomyosis. In this condition, the uterus is gradually getting ‘swollen’. Severe adenomyosis has been linked with reduced fertility.

7) Sperm quality

To have a successful pregnancy, you need a healthy egg and a healthy sperm. Even though male fertility declines slowly than their female partner, sperm quality is still an important factor in secondary sub-fertility.

Environmental factors such as cigarette smoke, unhealthy diet and pollutants are known to reduce the quality of sperm. Thus it is important for male partners to get themselves checked together with their wives.

8) Smoking

Smoking, for both women and men, has adverse effect on their fertility. Long term smoking can lead to poorer egg quality. Likewise, smoking also reduces men’s sperm quality even though his sperm quantity is normal.

So, you could have easily conceived your first child, but continuous smoking can make it harder to conceive your second child.

9) Stress

Stress is widely linked to sub-fertility. It’s not only work related stress, but stress of caring for your first child.

You may have sleep deprivation, time pressure and pressure juggling between work and child care. These can make it more challenging to try for a baby during the fertile period of the woman.

10) Change in health status

The older you get, chances are that you may have developed health conditions such as high blood pressure and diabetes. When these conditions are not well controlled, it reduces your fertility. It is important to have regular health check ups and initiate early intervention if needed.

The above are some common causes of secondary sub-fertility. If you are one of them, take the necessary step today to get yourself checked.

Last but not least, remember: “You have done it once, and you can do it again.”
