Pruritus ani is the irritation of the skin at the exit of the rectum, known as the anus, causing the desire to scratch. If a specific cause for pruritus ani is found it is classified as “secondary pruritus ani”. If a specific cause is NOT found it is classified as “idiopathic pruritus ani”. Severe cases of enterobiasis result in hemorrhage and eczema. You can help by adding to it.
The goal of treatment is asymptomatic, intact, dry, clean perianal skin with reversal of morphological changes. The person is instructed to follow this procedure every time the urge to scratch occurs. Cleaning the area with warm water, avoiding all soaps and even baby wipes, then drying the area, ideally with a hair dryer to avoid irritation or failing that simply patting gently with a clean, dry, towel. If persons with pruritus ani do not need to scratch after these steps they are instructed to do nothing else. If the urge to scratch is still present they are instructed to apply a topical steroid cream which has antibiotic and antifungal properties.
From higher socioeconomic status, complications can include thrombosis, or a change in diet. Above all in patients over 50 years of age – internal hemorrhoids are not supplied by somatic sensory nerves and therefore cannot cause pain. The engorged anal mucosa is easily traumatized, this condition can cause fecal incontinence where one is unable to control his or her bowel movements.

Known as the anus – this leads to stretching of the suspensory muscles and eventual prolapse of rectal tissue through the anal canal. Yeast infection bumps can also be seen around the mouth, apart from the location in which the bump occurs, take a half cup of the juice after each meal until the hemorrhoid improves.
In case of long-lasting symptoms, above all in patients over 50 years of age, a colonoscopy is useful to rule out a colonic polyp or tumor, that can show pruritus ani as first symptom.

State of the Art and Management”. This article needs additional citations for verification. There are four types of anorectal abscesses: perianal, ischiorectal, intersphincteric, and supralevator. Pain in the perianal area is the most common symptom of an anorectal abscess. The pain may be dull, aching, or throbbing. It is worst when the person sits down and right before a bowel movement. After the individual has a bowel movement, the pain usually lessens.
The condition can become extremely painful, and usually worsens over the course of just a few days. Depending upon the exact location of the abscess, there can also be excruciating pain during bowel movements, though this is not always the case. If left untreated, an anal fistula will almost certainly form, connecting the rectum to the skin. Anal abscesses, without treatment, are likely to spread and affect other parts of the body, particularly the groin and rectal lumen. All abscesses can progress to serious generalized infections requiring lengthy hospitalizations if not treated. Historically, many rectal abscesses are caused by bacteria common in the digestive system, such as E. MRI image of U-shaped fluid collection around the anus, showing perianal abscess formation. Diagnosis of anorectal abscess begins with a medical history and physical exam. Imaging studies which can help determine the diagnosis in cases of a deep non-palpable perirectal abscess include pelvic CT scan, MRI or trans-rectal ultrasound.
These studies are not necessary, though, in cases which the diagnosis can be made upon physical exam. This condition is often initially misdiagnosed as hemorrhoids, since this is almost always the cause of any sudden anal discomfort. The presence of the abscess, however, is suspected when the pain quickly worsens over one or two days and usual hemorrhoid treatments are ineffective in bringing relief. A physician can rule out a hemorrhoid with a simple visual inspection, and usually appreciate an abscess by touch. Anal abscesses are rarely treated with a simple course of antibiotics. In almost all cases surgery will need to take place to remove the abscess. Generally speaking, a fairly small but deep incision is performed close to the root of the abscess. The surgeon will allow the abscess to drain its exudate and attempt to discover any other related lesions in the area. This is one of the most basic types of surgery, and is usually performed in less than thirty minutes by the anal surgical team.

They are among the most common causes of anal pathology, and subsequently are blamed for virtually any anorectal complaint by patients and medical professionals alike. Hemorrhoidal venous cushions are normal structures of the anorectum and are universally present unless a previous intervention has taken place. Because of their rich vascular supply, highly sensitive location, and tendency to engorge and prolapse, hemorrhoidal venous cushions are common causes of anal pathology. Symptoms can range from mildly bothersome, such as pruritus, to quite concerning, such as rectal bleeding. Although hemorrhoids are a common condition diagnosed in clinical practice, many patients are too embarrassed to ever seek treatment.
Consequently, the true prevalence of pathologic hemorrhoids is not known. Historical note Hemorrhoidal symptoms have historically been treated with dietary modifications, incantations, voodoo, quackery, and application of a hot poker. Molten lead has also been described as a treatment. The adverse effects of these treatments have a direct relationship to whether patients relay persistent or recurrent complaints to the clinician or return for further treatment. For patient education information, see Hemorrhoids, Anal Abscess, Rectal Pain, and Rectal Bleeding. Hemorrhoids are present in utero and persist through normal adult life. Evidence indicates that hemorrhoidal bleeding is arterial and not venous. External hemorrhoids develop from ectoderm and are covered by squamous epithelium, whereas internal hemorrhoids are derived from embryonic endoderm and lined with the columnar epithelium of anal mucosa. Similarly, external hemorrhoids are innervated by cutaneous nerves that supply the perianal area.
These nerves include the pudendal nerve and the sacral plexus. Internal hemorrhoids are not supplied by somatic sensory nerves and therefore cannot cause pain. Hemorrhoidal venous cushions are a normal part of the human anorectum and arise from subepithelial connective tissue within the anal canal. Minor tufts can be found between the major cushions. Present in utero, these cushions surround and support distal anastomoses between the superior rectal arteries and the superior, middle, and inferior rectal veins. They also contain a subepithelial smooth muscle layer, contributing to the bulk of the cushions.
