RESUMO
BACKGROUND: While various medical treatments such as topical steroid ointment, antihistamine agent, and sedatives have been used for treating idiopathic intractable pruritus ani, they are not long-term solutions, due to the high recurrence rate. The aim of this study was to determine the effect of methylene-blue intradermal-injection therapy for treating patients with idiopathic intractable pruritus ani. Symptom improvement and recurrence rates were determined with a long-term follow-up. METHODS: A retrospective study was conducted from January 2011 to October 2013 on consecutive patients with intractable pruritus ani treated with methylene-blue intradermal injection. The therapy included 5 ml of 1% methylene blue and 15 ml of 1% lidocaine. Follow-up included a physical exam and satisfaction-score survey (1 = much worse, 2 = worse, 3 = no improvement, 4 = much better, 5 = gone completely) before treatment, 6 weeks after treatment, and 3 years after treatment to check patient status and recurrence rate. RESULTS: Of 103 treated patients, 96 were able to attend the 6-week follow-up visit. There were 58 (60.4%) males and 38 (39.6%) females with a mean age of 48.34 ± 10.21 years. Their mean satisfaction score at 6 weeks was 4.23 ± 0.86. Of the total of 96 patients, 9 (9.4%) patients scored 3 or less in their satisfactions score at 6 weeks. 62 (64.6%) patients were evaluated 3-year post-treatment. The satisfaction score at 3 years after treatment was 4.74 ± 0.57. Besides the 9 patients who initially failed treatment, 4 of the remaining 53 patients scored 3 or less in their satisfaction score surveys. Thus, the recurrence rate at 3 years was 7.5% (4/53). CONCLUSIONS: Methylene-blue intradermal injection can result in a high symptom improvement rate with low recurrence rate for patients with idiopathic pruritus ani.

Itch management can be particularly complicated in some small areas like the scalp or the anogenital region for many reasons: the frequently poor diagnosis of the causes of itch in these areas, the dense innervation of these areas, and the symbolic value of these areas for the human psyche. The diagnosis of itchy scalp is easier than that of anogenital pruritus. Clinical examination and a careful inventory of all diseases of the patient and of the local environment are necessary. Localized treatments are frequently used at both sites, whereas specific pharmaceutical formulations are necessary for the pilose or the mucous environment. Nonetheless, systemic treatments or psychological interventions can be very useful.

Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better compared to arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnostic. We studied 30 cases of CVT diagnosed in the department of neurology of the University Hospital of Fez (Morocco). Patients diagnosed with CVT signs between January 2003 and October 2007 were included in the study. Cerebral CT-scan was performed in 27 cases (90%) while the MRI examination was done in 18 patients (67%); and most patients (90%) received anticoagulant therapy. The mean age of our patients was of 29 years (age range between 18 days and 65 years). A female predominance was observed (70%). The clinical presentation of patients was dominated by: headache in 24 cases (80%), motor and sensory disability in 15 cases (50%), seizures in 10 cases (33%) , consciousness disorder in 10 cases (33%). CVT was associated to post-partum in 10 cases (33%), infectious origin in 8 cases (26%), Behcet disease in 2 cases (7%), pulmonary carcinoma in 1 case, thrombocytemia in 1 case and idiopathic in 7 cases (23%). The evolution was good in 20 cases (67%), minor squelaes were observed in 6 patients (20%), while major squelaes was observed in 2 cases. Two cases of death were registered. The CVT is a pathology of good prognosis once the diagnosis is promptly established and early heparin treatment initiated.

The prevalence of benign anorectal conditions in the primary care setting is high, although evidence of effective therapy is often lacking. In addition to recognizing common benign anorectal disorders, physicians must maintain a high index of suspicion for inflammatory and malignant disorders. Patients with red flags such as increased age, family history, persistent anorectal bleeding despite treatment, weight loss, or iron deficiency anemia should undergo colonoscopy. Pruritus ani, or perianal itching, is managed by treating the underlying cause, ensuring proper hygiene, and providing symptomatic relief with oral antihistamines, topical steroids, or topical capsaicin. Effective treatments for anal fissures include onabotulinumtoxinA, topical nitroglycerin, and topical calcium channel blockers. Symptomatic external hemorrhoids are managed with dietary modifications, topical steroids, and analgesics. Thrombosed hemorrhoids are best treated with hemorrhoidectomy if symptoms are present for less than 72 hours. Grades I through III internal hemorrhoids can be managed with rubber band ligation. For the treatment of grade III internal hemorrhoids, surgical hemorrhoidectomy has higher remission rates but increased pain and complication rates compared with rubber band ligation. Anorectal condylomas, or anogenital warts, are treated based on size and location, with office treatment consisting of topical trichloroacetic acid or podophyllin, cryotherapy, or laser treatment. Simple anorectal fistulas can be treated conservatively with sitz baths and analgesics, whereas complex or nonhealing fistulas may require surgery. Fecal impaction may be treated with polyethylene glycol, enemas, or manual disimpaction. Fecal incontinence is generally treated with loperamide and biofeedback. Surgical intervention is reserved for anal sphincter injury.

BACKGROUND: Anal pruritus affects up to 5% of the population. It is often persistent and the constant urge to scratch the area can cause great distress. Although usually caused by a combination of irritants, particularly faecal soiling and dietary factors, it can be a symptom of serious dermatosis, skin or generalised malignancy or systemic illness. OBJECTIVE: This article discusses the assessment and management of pruritus ani. DISCUSSION: It is important not to trivialise the symptom of anal pruritus and to enquire about patient concerns regarding diagnosis. Once serious pathology has been excluded, management involves education about the condition; elimination of irritants contributing to the itch-scratch cycle including faecal soiling, dietary factors, soaps and other causes of contact dermatitis; and use of emollients and topical corticosteroid ointments. Compounded 0.006% capsaicin appears to be a safe and valid option for pruritus not responding despite adherence to these conservative measures.

OBJECTIVE: Idiopathic pruritus ani is a common perianal condition that can be refractory to diligent perineal care. We wished to evaluate the efficacy and side effects of intradermal methylene blue for the treatment of refractory pruritus ani. METHOD: A prospective series of 49 patients with idiopathic pruritus ani, who had failed to improve with perineal care, were treated by a single surgeon. All patients received intradermal injections of methylene blue. Endpoints were patient symptom score, and complications (pain, dysaesthesia, skin necrosis, incontinence and anaphylaxis). RESULTS: Symptoms improved in 96% and resolved in 57% of patients after one treatment. All four patients who had a second treatment became symptom-free. Seven patients noticed changes in continence, all resolved between 10 days and 6 weeks. Two patients were distressed by their decrease in their perianal sensation. There was no skin necrosis or anaphylaxis. CONCLUSION: Treatment of refractory pruritus ani by intradermal injection of methylene blue is effective and generally well tolerated.

BACKGROUND: Pruritus ani is a common and socially embarrassing condition which is often poorly managed. It is often classified as idiopathic where the symptoms are usually transitory or secondary when a more persistent itch is experienced. The aim of this study was to establish the cause of pruritus ani in a group of patients referred to a combined colorectal and dermatological clinic, and to determine the most appropriate treatment. METHODS: Forty consecutive patients with pruritus ani were referred over a 6-month period from either the general practitioner or another hospital consultant to a combined colorectal and dermatological clinic. They were assessed by history, completion of a general health questionnaire, full examination of the skin, digital rectal examination, proctoscopy, sigmoidoscopy and patch testing. Patients were treated according to clinical findings at assessment. RESULTS: Thirty-four patients had a recognizable dermatosis, three had superficial perianal fissuring and three had a normal perineum; two required surgical intervention. Eighteen patients had a positive reaction when patch tested. All patients have shown an improvement or complete resolution of symptoms with treatment. CONCLUSION: This series has shown that the majority of patients presenting with pruritus ani have a dermatosis as the underlying cause of their symptoms and that many of them have developed contact sensitivities to the various topical medications used. These findings suggest that referral to a dermatologist in the first instance may be more appropriate.

Patients with idiopathic pruritus ani have an abnormal rectoanal inhibitory reflex and a lower threshold for internal sphincter relaxation during the saline continence test. This led to the hypothesis that these patients may exhibit abnormalities of the transient internal anal sphincter relaxation reflex. To study this, 23 men of median age 41 (range 27-64) years with idiopathic pruritus ani and 16 male controls of median age 39 (range 26-68) years were assessed using computerized ambulatory anorectal electromyography and manometry. Resting anal pressure, maximum anal squeeze pressure, internal sphincter electromyogram frequency, the number of internal sphincter relaxations and pudendal nerve terminal motor latency were similar for the two groups. The rise in rectal pressure during internal sphincter relaxation was higher in patients with pruritus than in controls (median (range) 29 (18-60) versus 18 (11-37) cmH2O, P < 0.01). Furthermore, the fall in anal pressure was greater in patients with pruritus than in controls (median (range) 39 (15-52) versus 29 (21-43) cmH2O, P < 0.01). The duration of internal sphincter relaxation was prolonged in patients compared with controls (median (range) 29 (18-55) versus 8 (5-12) s, P < 0.001). Fourteen patients reported staining of underclothes and 17 complained of perianal itch within 1 h of these episodes of abnormal internal sphincter relaxation. Pruritus ani may result from occult faecal leakage as a result of abnormal transient internal sphincter relaxation.

Seventy-five patients presented with the complaint of pruritus ani. The following prospective studies were employed to evaluate groups of these patients; (1) laboratory, including blood count, stool examination for ova and parasites, urinalysis, Sequential Multiple Analysis-12 serum studies, stool pH, and skin scrapings for fungi; (2) Minnesota Multiphasic Personality Inventory; (3) anal manometry; (4) elimination of dietary factors, and (5) topical ointment application. Many patients were concerned that a cancer caused the symptom. Once reassured, they tolerated the pruritus. Forty-eight to 50 per cent of these patients had poorly formed stools or incomplete stool evacuation; thus, soiling was frequent. An underlying skin problem was found in six patients with psoriasis and in one with erythrasma. Patients tended to worsen the problem by application of many medications and overzealous cleaning. Minor surgical problems of the anus should be corrected before other managements are instituted. Idiopathic pruritus ani responds to anal cleanliness, dietary discretion with avoidance of specific items by some patients, bowel habit regulation, and a mild topical hydrocortisone cream.
