Anogenital pruritus [keywords]
- [Lichen sclerosus in the genitourinary region]. [English Abstract, Journal Article, Review]
- Urologe A 2011 Oct; 50(10):1291-6.
Lichen sclerosus (LS) is a chronic inflammatory disorder of the skin and mucosa, presenting to genitourinary physicians, pediatricians, and dermatologists. It affects both sexes with a lower incidence in men than in women. Autoimmune factors, infections, and genetic disposition are implicated in its pathogenesis. The classic clinical picture is of atrophic white plaques in the anogenital region. Pruritus, soreness, difficulty retracting the foreskin, and obstructive urinary symptoms are frequent complaints. Early histological confirmation by biopsy is recommended. The disorder is usually highly responsive to ultrapotent topical steroids. This may help arrest or delay the progressive nature of this disorder. Surgical treatment may be needed in cases of disease progression despite medical therapy. Circumcision is a successful treatment, if LS is limited to the glans and foreskin. In cases of meatal stenosis meatoplasty and in cases of urethral involvement one- or two-stage oral graft urethroplasty is necessary.
- Recurrent vulvovaginal candidosis: focus on the vulva. [Journal Article]
- Mycoses 2011 Nov; 54(6):e807-10.
Recurrent vulvovaginal candidosis is a frequent disease with a serious impact on women's quality of life. Mostly, recurrences are caused by identical Candida strains suggesting C. albicans persistence in the female anogenital area. Objectives of the presented work were to identify the site of C. albicans persistence, to determine clinical symptoms and signs related to C. albicans positive vulvar cultures and to introduce a new therapeutic approach in women with RVVC. Women with an acute, culture-confirmed episode of RVVC at time of visit were included in this prospective case series. Swabs were obtained from both vagina and inter-labial sulcus. Women received a combined 20-day regimen of 100 mg oral fluconazole and ciclopiroxolamin cream topically. Follow-up visits were at 3, 6, 9 and 12 months. Of 139 women, 105 (76%) had at least one C. albicans positive culture from the external vulva. Vulvar positive cultures correlated with pruritus (OR 5.4; P < 0.001), vulvar edema (OR 3.8; P = 0.03) and fissures (OR 2.4; P = 0.03). Recurrence rates were 27%, 33% and 34% (at 6, 9, 12 months, respectively). The external vulva appears to represent a site of C. albicans persistence and source of endogenous re-infection in patients with RVVC. The combined treatment compared favorably with published fluconazole maintenance regimens.
- Efficacy, safety and tolerability of green tea catechins in the treatment of external anogenital warts: a systematic review and meta-analysis. [Journal Article, Meta-Analysis, Review]
- J Eur Acad Dermatol Venereol 2011 Mar; 25(3):345-53.
External anogenital warts (EGWs) are non-malignant skin tumours caused by human papillomavirus. They are one of the fastest growing sexually transmitted diseases. Current treatments are unsatisfactory. Green tea sinecatechin Polyphenon E ointment is a botanical extract from green tea leaves exhibiting anti-oxidant, anti-viral and anti-tumour properties.The aim of this study was to integrate valid information and provide basis for rational decision making regarding efficacy and safety of green tea extracts in the treatment of EGWs.A systematic search in electronic databases was conducted using specific key terms. Main search was performed independently by two reviewers. The accumulated relevant literature was subsequently systematically reviewed and a meta-analysis was conducted.Three randomized, double-blind, placebo-controlled studies evaluating efficacy and safety of Polyphenon E 15% and 10% in the treatment of warts were included in the systematic review and meta-analysis. A total of 660 men and 587 women were enrolled. Regarding primary outcome, both Polyphenon E 15% and 10% demonstrated significantly higher likelihood of complete clearance of baseline and baseline and new warts compared with controls. No significant heterogeneity was detected. Recurrence rates were very low. Commonest local skin sign was erythema and local skin symptom was itching.Efficacy of Polyphenon 15% and 10%, at least for the primary endpoint, is clearly indicated. Polyphenon E treatment exhibits very low recurrence rates and appears to have a rather favourable safety and tolerability profile. Recommendations for future studies should include evaluation of the efficacy of green tea catechins in the treatment of internal anogenital warts and direct comparison with its principal comparator, imiquimod.
- Pruritus ani as a manifestation of systemic contact dermatitis: resolution with dietary nickel restriction. [Case Reports, Journal Article, Research Support, Non-U.S. Gov't]
- Dermatitis 2011 Jan-Feb; 22(1):50-5.
Pruritus ani is a common distressing problem with numerous possible causes. When locally applied agents trigger irritation or allergic response, skin changes of dermatitis usually accompany the itch. Focal pruritus in the absence of dermatitis is not generally considered to be a manifestation of contact allergy. Furthermore, focal pruritus is not listed among the possible diverse presentations of the systemic delivery of a proven contact allergen. We report a case of a gentleman with a 1.5-year history of treatment-resistant pruritus ani. When patch testing revealed a positive reaction to nickel sulfate, he admitted to daily peanut butter consumption. His symptoms resolved with dietary nickel restriction. Patch testing may be useful in patients with pruritus of the anogenital region, not only to elucidate potential contact exposures contributing to the symptom but also to suggest possible dietary precipitants.
- Lichen simplex chronicus of anogenital region: a clinico-etiological study. [Historical Article, Journal Article]
- Indian J Dermatol Venereol Leprol 2011 Jan-Feb; 77(1):28-36.
Lichen simplex chronicus (LSC) of the anogenital region, is a benign, extremely uncomfortable disease.As very little is known about the cause of anogenital LSC (AGLSC), we undertook this study to determine various clinico-etiological factors involved in it and to assess the frequency of AGLSC.This was a descriptive study, including 105 patients with AGLSC, who attended the Dermatology clinic in our institute from September 2007 to June 2009. Detailed history, physical examination, and relevant investigations were done. The collected data were tabulated and analyzed.The frequency of AGLSC among patients presenting with anogenital pruritus was 2.54%. Primary AGLSC was more common than secondary AGLSC (69.5% vs. 30.5%). AGLSC manifested more commonly in males than in females (56.2% vs. 43.8%). The mean duration of the disease was 30.6 months. The common triggering factors for itching were sweating (41.9%), rubbing of thighs while walking for long distances (9.5%), and mental stress (5.7%). Pruritus of AGLSC was related to the intake of various food items in 37.1% of patients. In males, scrotum was the predominant site involved (89.8%), whereas in females, labia majora was the predominant site involved (78.2%). Nearly one-third of cases (30.5%) of AGLSC had some other dermatoses in the anogenital region.Though psychological factors are thought to play an important role in disease causation and perpetuation among AGLSC patients, their significance could not be ascertained by us.
- A cured patient who came back for consultation: neuropathic scrotal pruritus relieved after ipsilateral inguinal hernia repair. [Case Reports, Journal Article]
- Int J STD AIDS 2010 Sep; 21(9):658-9.
When no demonstrable cause is uncovered after excluding inflammatory dermatosis, infectious disease or a manifestation of anorectal disease, anogenital pruritus is often described as 'idiopathic'. Lumbosacral radiculopathy was described by Cohen et al. as one of the possible causes of 'idiopathic' anogenital pruritus. We report a case of a patient with chronic pruritus of the right scrotum that was relieved immediately post-ipsilateral inguinal hernia repair. This is, to the best of our knowledge, the first case of neuropathic scrotal pruritus secondary to direct nerve compression by an inguinal hernia. We propose that a proper examination for the presence of inguinal hernia be performed in the work-up for scrotal pruritus.
- Case Report of Bullous Pemphigoid following Fundus Fluorescein Angiography. [JOURNAL ARTICLE]
- Case Rep Ophthalmol 2010; 1(1):1-4.
PURPOSE:To report a first case of bullous pemphigoid (BP) following intravenous fluorescein for fundus angiography. Clinical Features: A 70-year-old male patient was admitted to the intensive care unit with BP and sepsis. He reported a history of fundus fluorescein angiography with a pre-diagnosis of senile macular degeneration 2 months prior to presentation. At that time, fluorescein extravasated at the antecubital region. Following the procedure, pruritus and erythema began at the wrists bilaterally, and quickly spread to the entire body. The patient also reported a history of allergy to human albumin solution (Plamasteril(R); Abbott) 15 years before, during bypass surgery. On dermatologic examination, erythematous patches were present on the scalp, chest and anogenital region. Vesicles and bullous lesions were present on upper and lower extremities. On day 2 of hospitalization, tense bullae appeared on the upper and lower extremities. The patient was treated with oral methylprednisolone 48 mg (Prednol(R); Mustafa Nevzat), topical clobetasol dipropionate 0.05% cream (Dermovate(R); Glaxo SmithKline), and topical 4% urea lotion (Excipial Lipo(R); Orva) for presumptive bullous pemphigoid. Skin punch biopsy provided tissue for histopathology, direct immunofluorescence examination, and salt extraction, which were all consistent with BP. After 1 month, the patient was transferred to the intensive care unit with sepsis secondary to urinary tract infection; he died 2 weeks later from sepsis and cardiac failure.
CONCLUSIONS:To our knowledge, this is the first reported case of BP following fundus fluorescein angiography in a patient with known human albumin solution allergy. Consideration should be made to avoid fluorescein angiography, change administration route, or premedicate with antihistamines in patients with known human albumin solution allergy. The association between fundus fluorescein angiography and BP should be further investigated.
- Efficacy of photodynamic therapy in vulvar lichen sclerosus treatment based on immunohistochemical analysis of CD34, CD44, myelin basic protein, and Ki67 antibodies. [Journal Article, Research Support, Non-U.S. Gov't]
- Int J Gynecol Cancer 2010 Jul; 20(5):879-87.
Lichen sclerosus (LS) is a chronic skin and mucosa inflammatory disease. It affects mainly the female anogenital area especially in postmenopausal period. The main symptoms include pruritus, burning, pain, sometimes urinary problems, or difficulties in defecation. Usually, porcelain-white plaques are seen in the skin and mucosa. The etiology and pathogenesis of LS are still uncertain. There are some research studies on possible genetic predisposition, yet autoimmune, hormonal, or infectious factors are not excluded. The typical treatment of LS is mainly pharmacological, although the alternative treatment method used in LS is photodynamic therapy (PDT), which is noninvasive technique based on selective destruction of lesions. Our study is focused on molecule markers of vascularisation (CD34), nervous cell function (myelin basic protein [MBP]), keratinocyte function (CD44), and proliferation index (Ki67) in cases treated with photodynamic method.A group of 100 patients treated in our department was included in the study. All 100 women had LS on the basis of clinical and histological criteria. All the subjects underwent PDT. In all cases, skin biopsies were taken before and after treatment, and samples were analyzed with CD34, CD44, MBP, and Ki67 antibodies using immunohistochemical staining.The study shows the high efficacy of PDT in LS treatment including beneficial changes to CD34, CD44, and MBP immunostained molecules. The Ki67 proliferation index did not change significantly. A significant increase of CD34 (microvessel density), MBP, and CD44 expression was confirmed in the histological images and in the partial or full remission of clinical objective and subjective symptoms.The PDT is a very effective therapeutic method in LS treatment.
- Topical calcineurin inhibitors for the treatment of vulvar dermatoses. [Journal Article, Research Support, Non-U.S. Gov't, Review]
- Eur J Obstet Gynecol Reprod Biol 2009 Sep; 146(1):22-9.
Repeated courses of potent topical corticosteroids and maintenance therapy with moderately potent topical corticosteroids are frequently needed to treat various forms of vulvar dermatoses, which are often characterized by an abnormal proliferation or activation of T lymphocytes. Because such therapeutic regimen is associated with an increased risk of potential side effects, particularly skin atrophy, an anti-inflammatory alternative to topical corticosteroids is desirable. The two non-steroid topical calcineurin inhibitors pimecrolimus and tacrolimus are immunomodulators that block the release of inflammatory cytokines from T lymphocytes in the skin while promoting cutaneous innate host defences. They are currently approved in Europe and in the United States of America as second-line anti-inflammatory agents for the treatment of atopic dermatitis. We provide a comprehensive summary of existing case reports, series of cases, and open-label prospective studies concerning the use of topical pimecrolimus and tacrolimus for the treatment of anogenital lichen sclerosus, genital lichen planus, vulvar lichen simplex chronicus and related pruritic vulvar dermatoses (chronic vulvar pruritus and allergic contact dermatitis of the vulva). The available data suggest that both topical calcineurin inhibitors may be effective and well tolerated in these vulvar dermatoses, although topical pimecrolimus may exhibit a better long-term tolerability profile. Being devoid of steroid-related side effects, they may represent a useful second-line therapeutic option for patients who are intolerant of, or resistant to topical corticosteroids. Controlled clinical trials and comparative studies are warranted to substantiate the promising findings summarized in this review.
- Mammary-like gland adenoma of the vulva: review of 46 cases. [Journal Article, Review]
- Pathology 2009; 41(4):372-8.
Hidradenoma papilliferum (HP) of the anogenital region, which was previously thought to be an apocrine tumour, is now believed to be derived from anogenital mammary-like glands (MLG) and is more accurately termed MLG adenoma. We sought to explore any ramifications that may have resulted from the perceived change in histogenesis of this tumour.We performed a clinicopathological audit of 46 cases.The mean age was 52 years and the range 31-90 years. Symptoms occurred in 23%, comprising nodules of increasing size 9%, pruritus 9% and bleeding 6%. Tumours occurred in the known distribution of mammary-like glands. The labia minora accounted for 50%, labia majora 40%, fourchette 7% and clitoris 3%. Tumours were described clinically as cystic in 42%, ulcerated 33% and solid 25%. Histologically, adjacent normal MLG were often present. There was striking diversity in histology. Tubular, papillary, cystic and solid areas were seen in various combinations. Two cell types, epithelial and myoepithelial, were present. The most common epithelial cell, the ductal cell, was seen alone in 43% or associated with apocrine metaplasia (57%) and/or foam cells (13%) and/or squamous cells (13%). Myoepithelial cells were usually flattened, but were prominent and clear cell in type in 11%. Stroma was variable in amount and either desmoplastic or sclerotic. Inflammatory cells were particularly associated with tumours involving the surface. Unusual architectural patterns resembled breast lesions such as erosive adenomatosis, sclerosing adenosis and ductal adenoma. No recurrence or association with malignancy was recorded.MLG adenomas demonstrate a marked diversity in histological pattern and cell morphology. The ductal cell and a site compatible with and/or the presence of adjacent normal MLG are the most characteristic features. Unusual vulvar tumours, which have been previously reported as erosive adenomatosis, sclerosing adenosis, papillary adenofibroma, syringocystadenoma papilliferans, etc., are variants of MLG adenomas.
