Patients with a history of recurrent candidiasis and who were using Depo-Provera (medroxyprogesterone acetate, DMPA) for contraception were reviewed in order to determine the time relationship between episodes of proven candidiasis, episodes of pruritus vulvae suggestive of this infection (but unproven), and injection of DMPA. Recently, patients were included in the study who had been given DMPA specifically to prevent recurrences of candidiasis even when the drug's contraceptive action was unnecessary, such as after sterilization. In all cases, the infection was initially treated with a vaginal candidacide, most commonly 1 week of an imidazole. The patients ranged in age from 19-37 years at the time of the 1st injection. Diabetes had been eliminated in all the cases. DMPA was given intramuscularly at a dose of 150 mg every 12 weeks. Prior to 1983, an estrogen supplement was prescribed in most cases in an effort to produce monthly menstrual periods. Estrogen supplementation is no longer used routinely, with amenorrhea the aim, although it is occasionally given to women who experience breakthrough bleeding. Candidal infection was considered proven when the branching filaments of the species were seen on a stained vaginal smear or when the species were cultured in a laboratory from a vaginal swab taken a symptomatic patient. With the exception of 2 patients, clinical candidiasis did not occur within the time in which 150 mg of intramuscular DMPA is known to suppress ovulation in all women, i.e., 12 weeks -- except in the presence of exogenous estrogen (cases 1, 2, and 14) and in one case (15) in which the patient had an unplanned conception prior to the injection. Both patients who experienced clinical despite the use of DMPA alone (cases 8 and 13) asked remain on the drug because believe it was responsible for their longest remissions in the past few years. The study seemed to provide evidence that DMPA will prevent a recurrence of clinical candidiasis in many women who are prone to this condition. The study further indicated that estrogens may predispose women to this infection.

Symptoms due to estrogen deficiency begin in the perimenopausal years and progress as serum levels of this hormone decrease Vasomotor instability, manifested by hot flushes or night sweats, may persist for several months to a few years. Psychologic symptoms include anxiety, tension, depression, insomnia, palpitations, and headaches. Atrophy of the genital epithelium may result in senile vaginitis with symptoms of irritation, burning, pruritus, dyspareunia, and even vaginal bleeding. Even the lower urinary tract mucosa is dependent upon estrogen. Postmenopausal osteoporosis affects 25 to 50% of older women and increases the risk for vertebral, hip, and other fractures. Estrogen therapy for menopausal complaints has received adverse publicity because several reports have indicated that unopposed estrogens increase the risk of endometrial cancer. Added progestogen not only negates this risk but reduces the incidence of endometrial adenocarcinoma in estrogen-progestogen users to less than that observed in untreated women. Estrogen replacement therapy does not increase the risk of breast cancer; the incidence of this malignancy, however, was also less in the estrogen-progestogen users when compared with either the untreated women or from that expected from the national cancer surveys. In evaluating postmenopausal women for hormone replacement, the benefits of estrogen-progestogen therapy must be weighed against possible risks.

It is noted that advertisements in medical journals recommend treatment of emotional symptoms in menopausal patients with Premarin (Ayerst brand of conjugated estrogens), Ogen (Abbott brand of piperazine estrone sulfate), or other compounds. There are no acceptable studies proving the usefulness of such combinations for symptoms relating to the menopause and no persuasive evidence to justify use of conjugated or any other type of estrogen in the treatment of emotional symptoms in menopausal women. Vasomotor symptoms, flushing, and sweats respond to estrogens. Symptoms do not recur if treatment is stopped after 1 or 2 years. Systematic or topical use of estrogens fails to promote the appearance of youthfulness. Vaginal pruritus and dyspareunia due to atrophic vaginitis may be relieved by estrogens either applied locally or orally. Libido is not heightened by exogenous estrogens but sufficient androgen doses cause virilization. It is doubtful if osteoporosis is favorably influenced by long-term use of estrogens. Estrogen therapy may cause spotting, menarrhagia, nausea, breast tenderness, or fluid retention. Prolonged use may cause increase in size of uterine fibroids. Personal or even family history of breast or genital cancer are considered contraindications.

Adverse reactions to radiopharmaceuticals are comparatively few in number. Various estimates quote an incident rate of 1 to 6 reactions per 100,000 injections. Other figures quoted are 1 in 800 for the bone-seeking radiopharmaceutical methylene diphosphonate, and 1 in 400 for the lung visualisation agent macroaggregated albumin. The very low numbers of reported adverse effects probably reflect the tiny amounts of material which are used in the formulation of radiopharmaceuticals. Adverse reactions to radiopharmaceuticals are usually mild and transient and require little or no medical treatment. A few reactions involve respiratory or circulatory collapse or loss of consciousness. Several fatalities have been reported with the liver scanning agent 99mTc (technetium 99m)-albumin colloid. Clinical manifestations may be categorised under the headings of vasomotor effects i.e. faintness, pallor, diaphoresis or hypotension, and anaphylactoid effects such as nausea, dermographism, wheezing, bronchospasm, erythema and pruritus. The most prominent group of radiopharmaceuticals that have been reported to produce adverse events are the diphosphonates, which are used for scanning the skeleton. Typical diphosphonate reactions include erythema (especially over the extremities), nausea, vomiting and malaise. The onset of reaction is usually 2 to 3 hours after injection. The second group of radiopharmaceuticals which give rise to adverse events are the colloids, which are used for liver and spleen scintigraphy. Typical colloid reactions include pallor, nausea, flush and pulse changes. Adverse events may also occur as a result of the patient's medication interfering with the disposition of the radiopharmaceutical. Although not usually hazardous or dangerous, such events may be so pronounced that a marked deviation in the expected pharmacokinetics may occur. Drug interactions can be conveniently categorised under the headings of unusual handling of the radiopharmaceutical because of pharmacological action, genuine in vivo interaction between the medication and radiopharmaceutical, drug-induced disease and interaction between the radiopharmaceutical and catheters or syringes. The most serious drug interactions are those where the patient is taking cortisone or cytotoxic agents prior to tumour scintigraphy. Other important effects occur in patients undergoing bone scanning who are receiving iron preparations. Nifedipine has been reported to produce quite severe problems in scanning, including difficulties in the radiolabelling of red cells (for cardiac scintigraphy), and other effects where the drug appears to prevent the transport of bone-seeking materials into the skeleton. Many drugs alter hormonal status and these effects may produce marked deviations from the expected biodistribution. Diethylstilbestrol (stilboestrol), digitalis, gonadotrophins, phenothiazines and cimetidine all increase estrogen levels in high doses.(ABSTRACT TRUNCATED AT 400 WORDS)

Urogenital complaints such as vaginal discomfort, dysuria, dyspareunia, recurrent lower urinary tract infections (UTIs) and urinary incontinence have been reported to affect more than 50% of postmenopausal women. These symptoms cause considerable suffering and an obvious reduction in quality of life for the afflicted individual, as well as being costly in economic terms for the health service. Urinary incontinence alone has been estimated to account for approximately 2% of health care costs in both the US and Sweden. Treatment with low potency estrogens given locally or orally has been shown to alleviate urgency, urge incontinence, frequency, nocturia and dysuria, but there is no conclusive evidence that estrogens alone improve or cure stress incontinence. Estrogen therapy has also been shown to cure or alleviate local urogenital atrophy symptoms, and to induce positive changes in the vaginal bacterial flora of postmenopausal women, which in turn reduces the risk of developing a UTI. There is little or no documentation to support the use of antibiotics in the treatment of local urogenital complaints such as pruritus, vaginal discomfort and discharge, or urinary incontinence in postmenopausal women. Antibiotics are, however, indicated for the treatment of UTIs, and in some cases for prophylactic treatment in women with recurrent UTIs. The number of women with urogenital complaints is expected to increase in the future, as the proportion of elderly women will be greater due to a higher life expectancy. Thus, in the future there will be an even greater need for simple, effective forms of treatment for large numbers of elderly women. Low potency estrogens given topically or orally have been shown to be an effective form of treatment for urogenital symptoms in postmenopausal women.

Fifteen percent of premenopausal women, 10-40% of postmenopausal women, and 10-25% of women receiving systemic hormone therapy experience urogenital atrophy. The most common symptoms are dryness, burning, pruritus, irritation, and dyspareunia. Estrogen loss, drugs, and chemical sensitivities are causes. Estrogen or hormone replacement therapy (ERT-HRT) is the treatment of choice in postmenopausal women. Dosages prescribed for menopause symptoms or to prevent osteoporosis (and, potentially, other conditions) can restore the vagina to premenopausal physiology and relieve symptoms. Concomitant progestins are necessary for women with an intact uterus to minimize or eliminate estrogen-induced endometrial cancer. Low-dosage oral and vaginal ERT can relieve urogenital atrophy but might not produce systemic effects. Progestins are not necessary with vaginal rings and vaginal tablets. If ERT is given only to treat urogenital atrophy, estrogen creams 1 or 2 times/week may prevent recurrence after symptoms are resolved. Progestins are not required for occasional estrogen cream use. Vaginal moisturizers provide longer relief by changing the fluid content of endothelium and lowering vaginal pH. Vaginal lubricants provide short-term relief. Women with contraindications to ERT-HRT could use lubricants for intercourse-related dryness or moisturizers for more continuous relief. The lay press promotes agrimony, black cohosh, chaste tree, dong quai, witch hazel, and phytoestrogens for vaginal dryness and dyspareunia; however, no evidence exists to support these specific claims. Pharmacists should be actively involved in identifying, preventing, and treating urogenital atrophy.

The cutaneous diseases associated with progesterone are autoimmune progesterone dermatitis, erythema multiforme-like eruption, drug-induced progesterone dermatitis and solar urticaria. Estrogen and progesterone are widely used in oral contraceptives and hormone replacement therapies, and they are rarely known to cause a photosensitive reaction. The mechanism of contraceptive-induced photosensitivity is uncertain. Estrogen, rather than progesterone, in the combined oral contraceptive pill has been most frequently implicated in the induction of photosensitivity. A 32-year-old woman presented with an erythematous patch with an itching sensation on the centrofacial area of a residual vitiligious lesion. She had a history of being previously treated with narrow band UVB for 1 year. Her skin lesions had mostly subsided, but some lesions continued. She underwent an in vitro fertilization-embryo transfer 3 months previously, and she then took synthetic progesterone for 3 weeks starting at the 4th week of pregnancy. She was in good health with neither a family history of photosensitivity nor a personal history of any other drug ingestion or topical agent such as sunscreen in association with the beginning of her lesions. Phototesting revealed her to be markedly photosensitive in the UVB and UVA ranges. The intradermal skin reactions to progesterone combined with irradiation with UVA or UVB were positive. We report here on an unusual case of photosensitivity that was localized in a vitiliginous lesion, and this was associated with the intramuscular injections of synthetic progesterone that she had received during an in vitro fertilization-embryo transfer.

Dystrophic epidermolysis bullosa pruriginosa (DEB-Pr) (OMIM 604129) represents a distinct variant within the DEB clinical spectrum. It is characterized by intense pruritus and distinctive nodular prurigo-like and/or hypertrophic lichenoid lesions mainly localized on the arms, legs and upper shoulders. DEB-Pr is caused by either dominant (DDEB-Pr) or recessive mutations in the COL7A1 gene encoding type VII collagen (COLVII). The full spectrum of COL7A1 mutations in DEB-Pr remains elusive and the genotype-phenotype correlation is largely incomplete. Here, we report and functionally characterize a previously unrecognized translationally silent exonic COL7A1 mutation that results in skipping of exon 87 and is associated with DDEB-Pr phenotypes in several members of three apparently unrelated Danish families. A haplotype segregation study suggested a common ancestor in these kindred. Functional splicing analysis of the mutant exon by a COL7A1 minigene construct and computational prediction for splicing regulatory cis-sequences prove that the mutation alters the activity of an exonic splicing enhancer (ESE) critical for exon inclusion. These findings substantiate for the first time the involvement of an ESE mutation in the pathogenesis of DEB and have implications for genetic counselling of Danish families with DDEB.

With increasing longevity in Poland, women can now expect to live around 40% of their lives after menopause, and there is a growing desire for older women to preserve their vitality sexual function and quality of life. The most common urogenital symptoms associated with menopause are dryness, followed by irritation or itching, and discharge, with a substantial number of post-menopausal women also being affected by dysuria. These symptoms are the result of vaginal atrophy which is in turn caused by reduced transudation through the vaginal epithelium and reduced cervical gland secretions resulting from post-menopausal estrogen depletion. Vaginal atrophy generally occurs 4-5 years after the last menstrual period and progressively increases in prevalence in the subsequent years. Importantly vaginal atrophy is strongly associated with sexual dysfunction, and lower urinary tract symptoms, such as frequency urgency nocturia and dysuria, as well as incontinence and recurrent infection are reported more frequently in the presence of vaginal atrophy Those symptoms, apart from being bothersome for the patients also negatively impact their quality of life. Consequently before irreversible changes occur, early detection and treatment of vaginal atrophy should be implemented. Estrogen therapy is the most commonly prescribed treatment. Estrogens restore the cytology pH and vascularity of the vagina, resulting in symptom resolution for the majority of treated women. Because vaginal atrophy symptoms tend to occur later than vasomotor symptoms, many women do not necessarily require or wish to take systemic estrogen treatment if their symptoms are restricted to the urogenital tract. Vaginal estrogen products deliver estrogen locally to vaginal tissues with little or no systemic absorption and provide an effective alternative to systemic estrogen therapy for these women. Various vaginal estrogen preparations such as conjugated equine estrogens, estradiol and estriol vaginal creams, a sustained-release intra-vaginal estradiol ring and a low-dose estradiol and estriol tablets are useful therapeutic options in the treatment of this condition. Moreover; a low dose treatment with a minimised systemic absorption rate may be considered in women with a history of breast cancer and associated severe vulvovaginal atrophy. It should be mentioned that vaginal lubricants once applied on a regular basis may also be effective in alleviating the symptoms of vaginal atrophy and should be offered to women wishing to avoid the use of local vaginal estrogen preparations and in cases where local estrogen therapy is contraindicated. Vaginal dehydroepiandrosterone (DHEA), vaginal testosterone, and tissue selective estrogen complexes are new, emerging therapies; however more clinical studies are necessary to confirm their efficacy and safety in the treatment of postmenopausal vulvovaginal atrophy.

The female genital and lower urinary tracts share a common embryological origin, arising from the urogenital sinus and both are sensitive to the effects of the female sex steroid hormones throughout life. Estrogen is known to have an important role in the function of the lower urinary tract and estrogen and progesterone receptors have been demonstrated in the vagina, urethra, bladder and pelvic floor musculature. In addition estrogen deficiency occurring following the menopause is known to cause atrophic change and may be associated with lower urinary tract symptoms such as frequency, urgency, nocturia, urgency incontinence and recurrent infection. These may also co-exist with symptoms of urogenital atrophy such as dyspareunia, itching, vaginal burning and dryness. Epidemiological studies have implicated estrogen deficiency in the aetiology of lower urinary tract symptoms with 70% of women relating the onset of urinary incontinence to their final menstrual period. Whilst for many years systemic and vaginal estrogen therapy was felt to be beneficial in the treatment of lower urinary and genital tract symptoms this evidence has recently been challenged by large epidemiological studies investigating the use of systemic hormone replacement therapy as primary and secondary prevention of cardiovascular disease and osteoporosis. The aim of this paper is to examine the effect of the sex hormones, estrogen and progesterone, on the lower urinary tract and to review the current evidence regarding the role of systemic and vaginal estrogens in the management of lower urinary tract symptoms and urogenital atrophy.
