SNIPPETS OF INFORMATION ON VAGINAL DISCHARGE

1-Vaginal discharge is a variable subject what is normal for some women may be abnormal for others.

2-If you have a vaginal discharge do not start treatment without a diagnosis. What you may consider as just Thrush may even be malignancy. I have recently two such cases in older women. Post menopausal women generally do not get thrush until they are diabetic or using HRT.

3-When you have recurring Candidiasis it can be due to any oestrogens you may be taking, high oestrogen pill, poor diabetic control and due to another variety of Candida called Candida Glabrata.
For this you require stronger treatment called Intraconazole 200 mgs twice a day three times a week , then twice a week for four weeks.
There are other forms of treatment which you GP will advise you on.

4-When should you treat the male partner in recurring Candidiasis? The candida store itself in the seminal vessels and a culture of the semen should be done, and if positive the partner should be treated. The should also be treated if they have an infection of the penis and be given a local cream.

5-In cases of recurring candidiasis saline was once or twice a day is very comforting, it also helps with other inflammatory conditions , such as vestubulitis.

6-The other treatment could be , change the pill, control diabetes and general hygiene, not share garments with each other.

7-Boric acid gelatine pessaries can be used once or twice. If used frequently they can be toxic.

8-Vagina can be painted with Aqueous Gentian Violet 0.5 percent to 1.0 percent, once a week.

9-Last but not the least Depoprovera injections are often very useful to control Candidiasis.
One has to be careful if it is used long it can cause 1.0 percent loss of bone density thus causing osteoporosis.

10-Avoid local antiseptics, perfumes and commercial moisturisers. Anti histamines and Amytriptaline at bedtime is very useful. Chronic treatment of recurring Candidiasis can cause eczematic rash and local dermatitis.

So the take home message is , take the correct treatment after the correct diagnosis.

The next post will be on the remaining Vaginal Infections and Inflammations.

SUPERFICIAL VAGINAL INFECTIONS

While we are talking about Dyspareunia, let us complete the subject by talking about Superficial Vaginal Infections(SVI) and inflammatory conditions called Vulvar Dermatoses, they also cause Dyspareunia, Vulvo Vaginal Pruritus and Vaginal Discharge.

All women have vaginal discharge during their reproductive life, in varying amounts during their menstrual cycle. I wonder if any of you have ever thought what a great house keeping function this discharge does by keeping the vagina clean, by washing away the dead cells and infections.
This normal vaginal discharge comes from the glands located in cervix and the vagina.
There is increased discharge at appropriate times such as ovulation and sexual arousal.
It is very important to keep the personal vaginal hygiene up to date.

The question is where do these infections come from, some of the organisms are locally present and under conditions favourable to them , they start playing around and cause disease, the commonest of these is a fungus called Candida.
On other occasions the infections come after child birth, pelvic operations, sexual intercourse, unscientific use of antiseptics, scented soaps, bubble baths and washes and the list can go on.
The main discharge problems along with pain and pruritus are as follows;
1-Candidiasis,2-Bacterial Vaginosis,3-Trichomonas,4- Nabothian Follicles,5-Cytolitic Vaginosis,6-Streptococcal Vaginosis,7-Erosive Vaginitis,8-Atrophic Vaginitis,9-Chlamydia,10-Gonococcus,11-Foreign Body, 12-Malignancy.

We have already discussed Chlamydia and Gonococcus in our previous post on PID, its difficult to discuss all the above conditions, but we will discuss the commonest of these being Candidiasis, Bacterial Vaginosis, and Trichomonas.

VULVO VAGINAL CANDIDIASIS(VVC)
It is estimated that 50 to 70 percent of women of all ages during their reproductive life suffer from at least one episode of VVC.
They generally do not suffer prepuberty and postmenopausal, because Candida loves oestrogen and oestrogen milieu and during this period of life is absent or low.
The infection is caused by a variety of Candida Albicans, the other variety of Candida often found is called Candida Glabrata and this requires special and stronger treatment.

Vulva and Vagina are both involved but often not together. In diabetic women VVC is often very severe the area looks very inflamed and swollen and the infection spreads to the groin and perianal area.

The symptoms of VVC can be mild or severe and they include severe itching, and maybe pain on passing urine. The risk factors are pregnancy when the oestrogen level is high, use of antibiotics, diabetes, and HRT.

The diagnosis is easy considering the history, and examination which shows redness and white curdy discharge in the area.
There is a simple office microscopic test using saline and sodium hydroxide which shows fine filaments which is called pseudohyphae, this test also shows Trichomonas vaginalis -this organism will be readily recognisable by its characteristic movement.
Bacterial vaginosis -have a special cell, called a clue-cells.
We can also see the hormone status of the individual by looking at the vaginal cells. So this test gives a lot of information. Still it is best to send a vaginal swab, cervical cytology and STD test in high risk patients.
The treatment of VVC is to remove the risk factors, control diabetes and for the very first episode, local vaginal nystatin cream for one week, this can be used during pregnancy as well. It is important to clear candidiasis in pregnant women because it can be passed on to the baby at birth as an oral infection, subsequently the baby can pass it on to the mother during breast feeding.
If candidiasis persists we have to look for the reasons for persistence, I often do a glucose tolerance test to exclude diabetes, if they are on high dosage oestrogen pill, change the pill or use a different type of contraception. Depoprovera and Mirena are good alternatives. Mirena is a progesterone releasing intrauterine device. DPMA is an injectable progestron which is given by a IM injection of 150mg every three months.
Both these are good long term contraceptives and help in getting rid of chronic candidiasis.
Long term recurrence requires long term treatment, which is given over a period of six months.
1- Vaginal nystatin pessaries every night or alternate night for six months.
2-Oral flucanazole of 100mg twice weekly for six months.
3-Oral ketoconazole 200mg a day for six months. This is hepatoxic, so the liver needs to be tested every two to three months.
The vagina can be painted with gentian violet weekly for several weeks.

Once again the subject that we have just discussed needs more time and information and this will be followed up in our next post.
