    INVITED ARTICLE I INVESTIGATION AND TREATMENT OF VAGINAL DISCHARGE AND PRURITUS VULVAE L Chan ABSTRACT The causes of vaginal discharge for pruritus vulvae in a patient are considered in three categories: common causes like vaginal candidosis, Trichomonal vaginitis, Gardnerella vaginitis; less common causes like gonococ- cal infection, Chlamydia infection and T-mycoplasma infection; and uncommon causes which include allergy to nylon underwear, human papilloma infection and eczema.

  • Venereal Vulval Diseases: a Hospital-Based Observational Study
    Original Article http://dx.doi.org/10.3126//njdvl.v17i1.23250 Clinico-epidemiological Profile of Women with Non- Venereal Vulval Diseases: A Hospital-Based Observational Study Joshi S1, Shrestha S1, Joshi A2 1Department of Dermatology and Venereology, 2Department of Gynecology and Obstetrics, Nepal Medical College Teaching Hospital, Attarkhel, Gokarneshwor, Kathmandu, Nepal Abstract Introduction: Vulval disorders can be of venereal and non-venereal etiology. Establishing non-venereal causation of vulval disorder helps in alleviating fears in patients with the condition. These patients are better dealt in a multidisciplinary clinic as patients with these disorders frequently visit dermatologists and gynecologists for the treatment. Objectives: To study the clinico-demographic profile of women with non-venereal vulval disorders and to determine their relative frequency. Materials and methods: This is an observational, descriptive study done at the Departments of Dermatology and Venereology and Gynecology and Obstetrics, Nepal Medical College Teaching Hospital. All consenting female patients with problems pertaining to female external genitalia were recruited for the study after excluding venereal diseases. Details of the patients were obtained and entered in a predesigned proforma. Results: Seventy-five females were recruited during a period of 20 months with a mean age of 34.79±17.90 years. Majority were married, uneducated and homemakers. Duration of disease ranged from three days to 35 years. Itching was the commonest presenting complaint (82.67%) followed by redness (32.00%), burning sensation (26.67%), white lesions (24.00%) and pain (24.00%). Commonest diagnosis was lichen sclerosus (17.33%), followed by candidiasis (14.67%). Patients presenting with vulval symptoms without lesions were diagnosed with non-specific vulval pruritus (9.33%) and vulvodynia (2.67%).

A cross-sectional study was conducted on 261 Accepted date: 2019-12-26 female college students. Data were collected using a structured questionnaire. Prevalence of premenstrual symptoms was 70.1%, and that of dysmenorrhea was 93.6%. Mothers were the main source (65%) of information about reproductive heatlh. Mood-swings/irritability (88.1%) and dysmenorrhea (93.5%) were most common of premenstrual symptoms and menstrual syndrome, respectively. Half of participants experienced severe dysmenorrhea (53.2%), however medical seeking behavior during menstrual period was poor (18.8%). Participants did not seek treatment because their menstrual problems did not interfere with their daily activities (80.2%). We conclude that health professionals should involve mothers in discussions about menstrual problems as mothers were the main source of information regarding reproductive health.

In this procedure, a device containing a laser is inserted into the vagina (transvaginal). The laser heats the vaginal tissue, causing changes to its structure. It is thought that this could improve support to the bladder. The aim is to reduce the symptoms of stress urinary incontinence.

  • Pruritus Vulva in Adolescent Females in Arar City

It is a common complaint in females of all ages. A pruritus vulva is not a condition. It is the symptom of various -most often benign, sometimes malignant – disorders. The study aimed at investigating the prevalence in valval itching and its manifestations and causes among young females in Arar city, KSA. Methods: This is across sectional study conducted among 300 of the studied women, Arar, KSA. Data were collected by using pre designed online questionnaire which include questions designed to fulfill the study objectives. Results: Pruritus vulvae were found in 30.7% of the studied sample. Most (60.7) of the examined girls age was between 15- 20 years old. 79.3% of the sample was single (unmarried). Manifestations of pruritus vulvae were 43.5% redness, 21.7% edema, 67.4% reported association of pruritus with increased vaginal discharge. 56.5% reported increased pruritus before menses and 37% after. Only 37% of the pruritus cases asked for medical help but only 23.9% got better after treatment.

Kim1* 1Department of Dermatology, Chonnam National University Medical School, 8 Hak-Dong, Dong-Gu, Gwangju, 501-757 and 2BK21 Project Team, College of Pharmacy, Chosun University, Gwangju, Korea. *E-mail: [email protected] Accepted July 27, 2011. Pruritus vulvae is caused by a variety of skin diseases, as well as by neuropathic/neurological, psychosomatic and psychiatric diseases. It is difficult to determine the pathogenesis of itching symptoms over the vulval area, but ongoing inflammatory reactions, may be responsible for lowering the perception threshold of itching (1, 2). A variety of topical treatments has been used to reduce genital pruritus, including menthol, camphor, tannin preparations, local anaesthetics, antiseptics, urea prepa- rations, glucocorticosteroids, immunomodulators and N-palmitoyl-ethanolamine-containing cream (3). General advice for relief of pruritic symptoms include avoiding sweating and occlusion of the skin, and reducing potential irritative cleansing habits. Empirical observation sup- ports the use of cold compression over the pruritic skin lesion to relieve unpleasant nociception, such as itch and sensation of heat. Thus, local cooling sense evoked by TRPM8 activation can give a wisdom of controlling Fig. 1. Excoriated whitish atrophic lichenified patch in the vulval area. pruritus as shown in this case. receptor and a longer action time than menthol. Thus we decided to use topical icilin (provided as a gift by Dr Edward Wei, Shasun Pharmaceutical, India) in this case.

  • Clotrimazole and Vaginal Haemorrhage
    Clotrimazole and vaginal haemorrhage Introduction Vaginal clotrimazole (Canesten Gyno®) is indicated for vulvovaginal infections with Candida species, and available as cream with applicators (dose 5 gram; strengths 10 mg/g, 20 mg/g and 100 mg/g) and as vaginal capsule (500 mg) or vaginal tablet (200 mg and 500 mg). There are three different treatment regimens: 1) Canesten Gyno 1®, over-the-counter (OTC) available as 500 mg tablet and capsule or 100 mg/g cream, as a single dose treatment; 2) Canesten Gyno 3®, available as 200 mg tablet or 20 mg/g cream for 3 days (prescription only); 3) Canesten Gyno®, OTC available as 10 mg/g cream for 6 days [1-6]. Vaginal clotrimazole was granted marketing authorization in the Netherlands in 1976 [1]. The imidazole clotrimazole has a broad spectrum of fungistatic activity against skin infections with yeasts and moulds by inhibiting ergosterol synthesis. Since ergosterol is the main component of fungal cell membranes, membrane permeability is altered and essential cell structures are lost. About 3 to 10% of vaginally applied dose is systemically absorbed [1-6]. Causes for abnormal vaginal haemorrhage, other than normal menstrual bleedings, differ between the reproductive- and postmenopausal phase. In the reproductive phase, menorrhagia may occur due to myoma, IUD and with anticoagulant therapy. Irregular or intermenstrual bleeding can occur spontaneously, or can be caused by early pregnancy, break-through bleedings with hormonal contraceptives and disorders of the perineum, vagina and cervix. Postmenopausal causes of vaginal haemorrhage are endometrial abnormalities, vaginal atrophy and the use of tamoxifen or hormonal therapy.
