Overview

Anal Fistula
An anal fistula is an abnormal tunnel that develops between the inside of the anus or rectum and the skin near the anus. It often develops after an infection or abscess in an anal gland. Symptoms may include persistent drainage, pain, swelling, irritation, or recurrent abscesses around the anus.
Pericarditis
Pericarditis is inflammation of the pericardium, the thin sac surrounding the heart. It can cause sharp chest pain that may become worse with deep breathing or lying down and improve when sitting forward. Viral infections are a common cause, but other infections, autoimmune diseases, medications, injury, and medical procedures can also contribute. Some cases resolve on their own, while others require treatment. Complications such as fluid accumulation around the heart can occur and may interfere with normal heart function.

Diagnosis

Anal Fistula
An anal fistula is diagnosed through a medical history and examination of the anus and surrounding skin. The healthcare professional may look for an external opening, drainage, swelling, or tenderness. A digital rectal examination may help identify the tract. Imaging such as MRI or ultrasound may be used when the fistula is complex, recurrent, or difficult to identify during examination.
Pericarditis
Pericarditis is diagnosed using the history, characteristic chest pain, physical examination, electrocardiogram, blood tests, and cardiac imaging. An electrocardiogram may show changes associated with inflammation, while blood tests can identify markers of inflammation or heart injury. Echocardiography can detect fluid around the heart and assess its effect on cardiac function. Chest imaging and additional tests may help identify an underlying infection, autoimmune condition, or other cause.

Prevention

Anal Fistula
Preventing anal fistula mainly involves reducing the risk of anal abscesses and treating infections promptly. People with inflammatory bowel disease should follow appropriate medical treatment and monitoring. Persistent pain, swelling, drainage, or recurrent abscesses around the anus should be evaluated by a healthcare professional rather than left untreated.
Pericarditis
Some causes of pericarditis cannot be prevented, but managing underlying inflammatory or systemic conditions and following medical advice after infections or heart procedures may reduce risk in certain situations. People with a previous episode should follow recommendations intended to reduce recurrence. New or unexplained chest pain should be assessed promptly because pericarditis can resemble other serious heart and lung conditions. Preventive measures depend largely on the underlying cause.

Risk Factors

Anal Fistula
Risk factors include a previous anal abscess, inflammatory bowel disease such as Crohn disease, recurrent infections in the anal region, previous anal or rectal surgery, and conditions that interfere with normal healing or immunity. A history of an anal fistula also increases the likelihood of recurrence.
Pericarditis
Risk factors for pericarditis include recent viral or other infections, autoimmune diseases, kidney failure, cancer, previous heart surgery, chest injury, radiation exposure, and certain medicines. A previous episode of pericarditis increases the chance of recurrence. People with systemic inflammatory diseases may be particularly susceptible. In many cases, however, no specific risk factor or cause is identified.
