Evaluation, management and future perspectives of anal pruritus: a narrative review.

PURPOSE: The without a time limitation. Most recent search was performed on 1st June 2022. RESULTS: Thorough history and physical examination are very important in view of multiple possible causes of anal pruritus. Most of the focus during examination is drawn on to the perianal region. A digital rectal examination and an anoscopy are essential. It is necessary aim of this narrative review is to overview the classification, diagnostics, possible treatment options and future perspective of anal pruritus. METHODS: The search was performed by two authors (AD and MJ) independently in the following electronic databases: PubMed, EMBASE, Web of Science, Cochrane Library, CENTRAL and the Allied and Complementary Medicine Databases (AMED). Search was restricted to English language only to avoid moisture and the use of soaps in the perianal region. Furthermore, the patient should avoid certain foods and increase the intake of fiber. If the symptoms do not resolve, topical steroids, capsaicin (0.006%) and tacrolimus (0.1%) ointments may be used. For intractable cases, intradermal methylene blue injection might give a long-lasting symptom relief. CONCLUSION: Anal pruritus is a long-term deteriorating quality of life issue. Most of the time it is a symptom with a difficult diagnosis. Thorough history and examination should be performed for the best possible treatment.

Causes and Management of Pruritus Ani.

CASE SUMMARY: A 48-year-old healthy man presented to the office reporting a long-standing history of anal pruritus. He had tried various over-the-counter creams without much success. Besides an anal fissure in the past, which responded to nitroglycerin ointment, his medical history was unremarkable. On physical examination, he was found to have grade I hemorrhoids and mild fecal smearing on perianal skin. Recent colonoscopy and laboratory work ordered by the primary care provider were normal. He was counseled on common inciting agents and local irritants and was advised on hygiene, diet modification, and stool-bulking agents. The colorectal surgeon recommended that the patient keep a journal about his symptoms, foods, and household chemicals used. He was seen twice more over the course of 6 months to pinpoint the cause of his pruritus. A short-course trial of topical steroid, barrier cream, and topical tacrolimus was not helpful. A biopsy of perianal skin was performed and was unrevealing. Eventually, given the persistence of symptoms, it was decided that he would undergo methylene blue injection to address his pruritus (Fig. 1). The procedure consisted of several intradermal and subcutaneous injections of 10 mL of 1% methylene blue combined with 7.5 mL of 0.25% bupivacaine with adrenaline (1/100,000) and 7.5 mL 0.5% lidocaine. After the methylene blue injection, the severity of his symptoms improved, but pruritus still persisted. A methylene blue injection of the same concentration was repeated in 3 months with complete resolution of symptoms.

Management of Common Benign Anorectal Disease: What All Physicians Need to Know.

Benign anorectal conditions produce anal pain, rectal bleeding, or discharge from the perianal region, which are highly prevalent symptoms in the general population. Hemorrhoidal disease, anal fissure, perianal abscess, proctalgia syndromes, and pruritus anii are the most common clinical disorders. Well-trained physicians, irrespective of their specialty, can treat most of these disorders and refer them to a specialist in proctology only when necessary. The aim of this review is to provide a practical guide to the management of benign anorectal disorders in terms of their initial management and the criteria for specialist referral.

[Clinical observation of chronic perianal eczema treated with auricular point sticking therapy and western medication].

OBJECTIVE: To observe the differences in the therapeutic effects on chronic perianal eczema between auricular point sticking therapy and auricular sticking pseudo-press therapy on the basis of the treatment with western medication. METHODS: Ninety patients were randomized into an auricular therapy group and an auricular pseudo-press therapy group (pseudo group), 45 cases in each one. The western medication was used in both of the groups. In the auricular therapy group, the auricular sticking method with semen vaccariae was added at Fengxi (SF1,zi), Shenshangxian (TG2p), Duipingjian (AT1,2,4i), Fei (CO14), Pi (CO13), Gangmen (HX5). The patients were advised to press each auricular point every day. In the pseudo group, the plaster was applied to the same auricular points without semen vaccariae used and pressing manipulation given. The auricular sticking therapy was used once every three days in the two groups. The treatment for 2 weeks was as one session and one or two sessions of treatment were given accordingly. The severity of perianal itching, the area of skin lesion, the form of skin lesion and the score of dermatology life quality index (DLQI) and the clinical therapeutic effects were compared before and after treatment in the two groups. The adverse reaction and recurrence rate in 1-year follow-up visit were observed during treatment. RESULTS: After treatment, the itching degree, the area of skin lesion, the form of skin lesion and DLQI score were all reduced apparently as compared with those before treatment in the patients of the two groups (all P<0.05). The results in the auricular sticking therapy group were better than those in the pseudo group (all P<0.05). The curative and markedly effective rate and the total effective rate in the auricular sticking therapy group were apparently better than those in the pseudo group[52.3% (23/44) vs 19.0% (8/42), 97.7% (43/44) vs 76.2% (32/42), both P<0.05]. The recurrence rate in the auricular sticking therapy group was lower apparently than that in the pseudo group[7.0% (3/43) vs 37.5% (12/32), P<0.05]. No severe adverse reactions were found during the treatment in the two groups. CONCLUSIONS: The auricular sticking therapy combined with western medication effectively release itching in chronic perianal eczema and local skin lesions, improve the living quality and reduce recurrence rate.

Diagnosis and Management of Anorectal Disorders in the Primary Care Setting.

Anorectal disorders are very common among a wide population of patients. Because patients may be embarrassed about the anatomic location of their symptoms, they may present to care late in the course of their illness. Care should be taken to validate patient concerns and normalize fears. This article discusses the diagnoses and management of common anorectal disorders among patients presenting to a primary care physician.

Anal Health Care Basics.

Despite the fact that countless patients suffer from anal problems, there tends to be a lack of understanding of anal health care. Unfortunately, this leads to incorrect diagnoses and treatments. When treating a patient with an anal complaint, the primary goals are to first diagnose the etiology of the symptoms correctly, then to provide an effective and appropriate treatment strategy.The first step in this process is to take an accurate history and physical examination. Specific questions include details about bowel habits, anal hygiene, and fiber supplementation. Specific components of the physical examination include an external anal examination, a digital rectal examination, and anoscopy if appropriate.Common diagnoses include pruritus ani, anal fissures, hemorrhoids, anal abscess or fistula, fecal incontinence, and anal skin tags. However, each problem presents differently and requires a different approach for management. It is of paramount importance that the correct diagnosis is reached. Common errors include an inaccurate diagnosis of hemorrhoids when other pathology is present and subsequent treatment with a steroid product, which is harmful to the anal area.Most of these problems can be avoided by improving bowel habits. Adequate fiber intake with 30 g to 40 g daily is important for many reasons, including improving the quality of stool and preventing colorectal and anal diseases.In this Special Report, we provide an overview of commonly encountered anal problems, their presentation, initial treatment options, and recommendations for referral to specialists.

[Pruritus ani]. / Pruritus ani.

INTRODUCTION: Pruritus ani is defined as a dermatologic disease characterized by itching and/or burning in the perianal area. It occurs in 15% of the population. Men are affected more frequently than women, in the ratio 4:1. It is accompanied by an irresistible desire to scratch in the perianal area. Pruritus ani is divided into two subtypes: primary (idiopathic) and secondary. In idiopathic (primary) pruritus it is not possible to detect any other cause of itching. Secondary pruritus has an obvious causal origin.The aim of this paper is to offer a complex overview of possible causes, diagnostic procedures and treatment possibilities of this unpleasant and annoying disease. METHODS: We have researched available publications using PubMed and MEDLINE databases, focusing on articles on anal pruritus. At first the key word "Pruritus ani" was put in without any restrictions. Subsequently, we limited the selection by the time period of 5 years and 10 years; then we looked up articles in English, German and Czech languages, and finally review articles, clinical trials and others. RESULTS: 574 articles were found without entering any restrictions; 45 of them were review articles and 25 clinical trials. 437 articles were in the English language and 40 of them were review articles. 44 were in the German language and 1 of them was a review article. A total of 33 articles were found with a 5-year time limit. 6 of them were review articles and 4 were clinical trials. 66 articles from the last 10 years were found. 14 of them were review articles and 10 were clinical trials. In most of the other articles among the total number of articles found, pruritus ani was mentioned only marginally in articles focused on different topics. We have not found any summary articles on this topic in Czech publications. CONCLUSION: Pruritus ani is a common disease with a number of causes; therefore, effective treatment may be insufficient in the initial stages. The therapy is focused on the primary cause, if found. Broad differential diagnosis options need to be taken into consideration, and reevaluation of the therapy is a priority. When no obvious secondary cause is found, the empiric treatment is focused on an improvement of hygiene and change in the life style, removal of common irritators, and protection of perianal skin.

[Differential diagnosis of anal eczema]. / Differenzialdiagnose des Analekzems.

Dermatologic disorders often show involvement of the (peri)anal skin. However, diagnosis of (peri)anal dermatoses is often difficult even for experienced dermatologists due to delayed clinical presentation or prior treatment with over-the-counter medications. The distinct anatomical conditions of the (peri)anal region results in atypical clinical presentation of common dermatoses. Typical symptoms include pruritus, burning, bleeding and pain. Careful history of symptoms, stool, hygiene, sexual practice as well as thorough inspection of the entire body and proctological examination are crucial to make the correct diagnosis. In case of atypical presentation or uncertainty a biopsy needs to be obtained to ensure correct diagnosis and treatment.

Common anorectal conditions: evaluation and treatment.

Anorectal conditions are frequently encountered clinical entities but are often misunderstood and misdiagnosed. Although the most common anorectal disorders are not considered life threatening, they can negatively impact patients' activities of daily living and quality of life. Comprehensive anorectal examination, including the use of anoscopy, has become a "lost art," and graduate medical education programs should utilize more formal training in this area. This review discusses the comprehensive anorectal exam and the diagnosis and management of three common anorectal disorders: hemorrhoids, anal fissure, and pruritus ani.

[Acute anal pain]. / Douleur anale aiguë.

Anal pain is a common reason for consultation, whose etiology is varied and should not be limited to the hemorrhoidal disease. The purpose of this article is to conduct a review of the literature on anorectal pathologies most frequently encountered and make recommendations regarding their management.

Pruritus ani: more than a decade of personal experience in Lebanon.

INTRODUCTION: Pruritus ani is a common medical condition that is difficult to treat in the absence of obvious predisposing factors. Hereby, we report more than a ten-year experience in the management of pruritus ani stressing the importance of early detection, identification of the etiology, and management. METHODOLOGY: A total of 124 patients were managed in the surgical clinic. The follow-up was between 11 to 17 months. All patients had the symptoms for a period of time ranging between 6 and 40 months. Patients were treated according to their respective etiology. Medical cases like contact dermatitis and psoriasis were treated by applying proper topical ointments, while other cases like anal fissure and fistula were treated surgically. Idiopathic patients were treated by tattooing (injection to perianal skin with methylene blue). RESULTS & DISCUSSION: The majority of patients with known medical etiology responded favorably to conservative treatment (≈ 92%). In addition, surgical management for anorectal disorders like hemorrhoids and fistula showed a consistent improvement (94%). However, patients who had their symptoms neglected for longtime or had used over the counter medication without a proper medical follow-up, experienced a lower success rate of cure (76%). CONCLUSION: Patients who were diagnosed and treated at first hand, showed better results than those who sought late medical advice and management (i.e. > 18 months). In light of the above, a multidisciplinary team approach consisting of a proctologist, a gastroenterologist and a dermatologist is recommended.

Pruritus ani: diagnosis and treatment.

Pruritus ani is a common condition with multiple causes. Primary causes are thought to be fecal soiling or food irritants. Secondary causes include malignancy, infections including sexually transmitted diseases, benign anorectal diseases, systemic diseases, and inflammatory conditions. A broad differential diagnosis must be considered. A reassessment of the diagnosis is required if symptoms or findings are not responsive to therapy. The pathophysiology of itching, an overview of primary and secondary causes, and various treatment options are reviewed.

Management of anaemia and other treatment complications.

Antiviral treatment for hepatitis C virus infection has dramatically changed with the advent of triple therapy including telaprevir or boceprevir, which is associated with a new spectrum of adverse events. These may lead to dosage reduction and early discontinuation of therapy. An increase in the frequency and severity of anaemia was reported in clinical trials for both drugs, and skin disorders including rash and pruritus occurred more frequently with the telaprevir-based regimen. The first-line management of anaemia is ribavirin dose reductions. In cirrhotic patients, aggressive ribavirin dosage reductions, erythropoietin alpha and blood transfusions are effective in managing anaemia. Several deaths and cases of severe infections and hepatic decompensation were reported in cirrhotics treated in real-life setting. Patients with platelet count ≤ 100,000/mm(3) and serum albumin < 35 g/L should not be treated with triple therapy as it is related to a high risk of developing severe complications. The management of rashes, if well planned, does not require telaprevir discontinuation. However, approximately 5% of rashes were severe and a few cases were classified as severe cutaneous adverse reactions leading to treatment discontinuation. Successful treatment can be enhanced by a strong patient support network including a multidisciplinary team.

Assessment and treatment of three common anorectal conditions.

This is the second of two articles about the kinds of anorectal problem with which people can present at emergency departments. The first article concerns common symptoms and anorectal examination, while this one discusses the diagnosis and treatment of three common anorectal problems that can be managed by nurse practitioners: haemorrhoids, anal fissure and pruritus ani. Unexpected diagnoses might be found on examination and nurse practitioners should refer these patients to appropriate specialists.

Prurito anal idiopático: revisión bibliográfica y presentación de protocolo de tratamiento / Idiopathic pruritus ani: literature review and presentation of treatment protocol

Introducción: El prurito anal es un síntoma de difícil tratamiento en ausencia de factores predisponentes. Cuando no se logra identificar una causa evidente es habitualmente llamado "prurito anal esencial, primario o idiopático" y en los casos de adjudicarse el síntoma a otra patología se lo refiere como prurito anal secundario. El prurito anal esencial es una patología que representa un desafío para el médico tratante debido al poco consenso sobre el tratamiento de la misma. Objetivo: Realizar una revisión bibliográfica sobre prurito anal primario o idiopático. Presentar un algoritmo de diagnóstico y de tratamiento de pacientes que consultan por esta patología. Efectuar una evaluación inicial de los resultados obtenidos a corto plazo. Lugar de aplicación: Centro Privado de Cirugía y Coloproctología de la Ciudad de Buenos Aires. Diseño: Estudio retrospectivo, descriptivo, observacional y longitudinal. Pacientes y métodos: Se presentan 24 pacientes con diagnóstico de prurito anal esencial que fueron sometidos a tratamiento escalonado del mismo. Resultados: Se obtuvo respuesta favorable completa (ausencia del síntoma prurito por un período mayor a 15 días y con ausencia de lesiones por rascado) en 22 de los 24 pacientes (91,66%), en 2 pacientes (8,33%) se obtuvo respuesta casi completa (mejoría que se traduce en prurito leve sin lesiones cutáneas). No hubo recurrencias ni empeoramiento de los síntomas en ningún paciente. Conclusiones: La mayoría de los casos de prurito anal se deben a una causa coloproctológica o dermatológica, siendo menos frecuentes los casos en los que no se observa una causa responsable. Esta situación tiene relativa frecuencia y representa un desafío tanto para el médico tratante como para el paciente.(AU)

Introduction: Pruritus ani is a symptom of difficult treatment in the absence of predisposing factors. When not able to identify an obvious cause is usually called "essential, primary or idiopathic pruritus ani" and in case of winning the symptom to another condition is referred secondary anal itching.

[Observation of therapeutic effect on perineal, crissal and progenital pruritus treated with acupuncture according to differentiation].

OBJECTIVE: To observe the therapeutic effect and safety of perineal, crissal and progenital pruritus treated with acupuncture according to differentiation. METHODS: Self-control method was applied in these 32 cases. Changqiang (GV 1), Huiyin (CV 1), Qugu (CV 2), Sanyinjiao (SP 6) and Ashi points etc. were punctured as main points, and adjunct points were added according to differentiation: Taichong (LR 3) and Ququan (LR 8) etc. were added for wind and heat excess of liver meridian, Xuehai (SP 10) and Quchi (LI 11) etc. were added for blood deficiency and wind dryness. Itchiness, skin lesions sign scores and therapeutic effects were observed before and after treatment. RESULTS: The total scores of itchiness before and after treatment were 6.06 +/- 1.46 and 2.19 +/- 1.71 respectively, and the total scores of skin lesions sign were 4.38 +/- 2.21 and 1.50 +/- 1.44, indicating that the scores and the total scores of itchiness and skin lesions sign reduced obviously after treatment (P < 0.05, P < 0.01); the cured and markedly effective rate was 73.4% (11/15) for wind and heat excess of liver meridian, and 70.6% (12/17) for blood deficiency and wind dryness, presenting similar therapeutic effect (P > 0.05). Hematoma or ecchymosis appeared in 2 cases, and disappeared spontaneously after 2-3 days, without obvious adverse reaction. CONCLUSION: Simple perineal, crissal and progenital pruritus treated with acupuncture according to differentiation is effective, safe and applicable.
