Ans. is D. i.e Trichomonas vaginalis
The other organisms listed cause gastrointestinal disease.
- Trichomonas vaginalis is the only organism listed to primarily affect the genital tract rather than the intestinal tract.
- Alfred Francois Donné (1801–1878) was the first to describe a procedure to diagnose trichomoniasis through “the microscopic observation of motile protozoa in vaginal or cervical secretions” in 1836.
- Trichomonas Vaginitis is caused by trichomonas vaginalis which is a flagellated protozoan.

- The vaginitis it causes is characterized by a frothy, yellow discharge.
- The organism can be identified in Pap smears, or, more reliably, by special culture techniques that are becoming more widely available
- Infection in men is usually asymptomatic, but prostatitis and urethritis can also occur.
Investigations
- IOC– Saline microscopy– Typical motile flagellated trichomonas seen or some kind of motility seen trichomonas may be seen on a pap smear.
- If Pap smear shows trichomonas, do saline microscopy to further confirm the diagnose before initiating treatment.
- Gold standard investigation: Culture on- Feinberg’ Whittington media or Diamond media.
- Amine test/whiff test. i.e. 10% KOH added to discharge-May be positive/or negative due to its association with Bacterial vaginosis.
Diagnosis
- Examination of wet film at 35°C
- Gram stain or Leishman stain is negative.
- Culture diagnosis
- Cytology
- PCR and NAAT(most sensitive)
- Antigen testing
- Pap smears a greyish blue pear-shaped structure without the flagella.
- A woman diagnosed with Trichomoniasis should also be evaluated for Other venereal diseases.
Treatment with metronidazole is indicated for both the patient and the sexual partner(s).
A woman diagnosed with Trichomoniasis should also be evaluated for which of the following?
- The same sexual encounters that spread trichomoniasis can also spread a wide variety of other sexually transmitted diseases, including herpes, human papillomavirus, syphilis, gonorrhea, chlamydia, and AIDS.
- Additionally, the lesions produced by the trichomoniasis particularly facilitate the spread of the AIDS virus, since the normal mucosal barrier is breached.
- The woman’s chance of transmitting AIDS to her partner is also increased by the presence of the trichomoniasis open sores.
A 26-year-old lady, complains to her gynecologist of discomfort during intercourse. Pelvic examination demonstrates a frothy, yellow-green vaginal discharge with a strong odor and small, red, ulcerations of the vaginal wall. A wet mount preparation demonstrates motile, flagellated protozoa. Which of the following is the most likely causative organism?
Ans. is B. i.e. Trichomonas vaginalis
- Trichomonas vaginalis, the causative organism of trichomoniasis, is a single-celled protozoan parasite with a predilection for infecting the vagina.
- The organism can be identified with intra-office wet mount preparations, cultured, or recognized on Pap smears (although this should be confirmed by culture, as the Pap smear is not a particularly reliable method).
- Candida albicans is a spore- and hyphae -forming fungus that can affect the vagina, often producing a discharge with a white, “cheesy” appearance.
- Entamoeba histolytica is an amoeba that can infect the gut.
- Giardia lamblia is a flagellated parasite that can infect the gut.

Pruritis of vulva may be a symptom of:
Ans. is D. i.e. All of the above.
Pruritus vulvae is itchiness of the vulva.
Causes: Itch due to infections
- Candida albicans infection (vulvovaginal thrush) is the most important microorganism to consider in a postpubertal woman with vulval itch.
- Bacterial vaginosis causes a frothy, malodorous discharge, and uncommonly causes vulval itch, possibly as a result of contact dermatitis.
- Genital viral warts are often itchy.
- Pinworms can reside in the vagina or anus and cause itch when they exit at night.
- Infections that rarely cause vulval itch include cytolytic vaginosis (associated with vaginal lactobacilli) and trichomoniasis.
Itch due to an inflammatory skin condition
Irritant contact dermatitis is the most common cause of an itchy vulva at all ages. It may be due to diverse causes, including:
- Age-related prepubertal or postmenopausal lack of estrogen
- Underlying tendency to atopic dermatitis
- Scratching for another reason
- Friction from skin folds, clothing, activity, or sexual intercourse
- Moisture due to occlusive underwear
- Urine and/or feces
- Soap or harsh cleanser
- Frequent washing
- Inappropriate or unnecessary chemical applications, including over-the-counter or prescribed medications
- Fissuring of the posterior fourchette
- Normal, excessive or infected vaginal secretions
The severe vulval itch may be due to:
- Lichen simplex
- Lichen sclerosis
- Lichen planus
Other common skin disorders that may cause vulval itch include:
- Psoriasis
- Seborrhoeic dermatitis
- Allergic contact dermatitis*
- Irritant or allergic contact urticaria
- Dermographism
- Folliculitis
Potential vulval allergens include:
- Methylisothiazolinone, a preservative in moist wipes
- Various textile dyes in underwear
- Fragrance in a douche or antiperspirant
- Rubber accelerants in condom, menstrual cup or underwear
- Latex rubber and semen are potential causes of contact urticaria.
Itch due to neoplasia
Benign and malignant neoplastic disorders of the vulva are often asymptomatic in their early stages, but they can cause itch. The most common cancerous lesions are:
- Squamous intraepithelial lesions (SIL, also known as vulval intraepithelial neoplasia or VIN)
- Extramammary Paget disease
- Invasive vulval cancer (squamous cell carcinoma)
Itch due to neuropathy
The finding of the cervix as shown in the picture below represents?
Ans. is D. i.e. All of the above.
- A strawberry cervix is a finding upon examination where the cervix has a punctate and papilliform appearance.
- It is named because of the superficial appearance of a strawberry.
- As opposed to more general inflammation of the cervix found in cervicitis, the strawberry cervix is considered to be selectively associated with Trichomonas infections.
- Only 2% of women with the infection will have a “strawberry” cervix or vagina on examination. This is due to capillary dilation as a result of the inflammatory response.
