Overview

Avascular Necrosis
Avascular necrosis, also called osteonecrosis, occurs when reduced blood supply causes bone tissue to die. It most often affects the hip but can involve other joints such as the knee, shoulder, or ankle. Early disease may cause no symptoms, while progressive damage can produce persistent pain, stiffness, reduced movement, and eventually collapse of the affected bone or joint surface. The condition may develop gradually and can be associated with injury, certain medicines, medical conditions, or other factors that impair blood flow to bone.
Genital Herpes
Genital herpes is a sexually transmitted infection caused by herpes simplex virus, usually HSV-2 or HSV-1. It can cause painful blisters, sores, or ulcers around the genitals, anus, or nearby skin, although many infected people have mild or unrecognized symptoms. After infection, the virus remains in the body and can reactivate, causing recurrent outbreaks. Symptoms and recurrence patterns vary between individuals.

Diagnosis

Avascular Necrosis
Diagnosis is based on symptoms, physical examination, medical history, and imaging of the affected bone. X-rays may appear normal in early disease, while magnetic resonance imaging can detect changes at an earlier stage. Additional imaging may help determine the extent of bone damage or joint collapse. Blood tests and other investigations may be used to identify an underlying condition or contributing cause, particularly when disease occurs at an unusual age or without an obvious risk factor.
Genital Herpes
Diagnosis may be based on the appearance and location of characteristic genital lesions together with the person’s symptoms and sexual history. When lesions are present, a swab from a fresh lesion can be tested using molecular methods to detect herpes simplex virus. Blood tests may be useful in selected circumstances, particularly when there are no lesions but a specific clinical question about previous infection needs to be addressed.

Prevention

Avascular Necrosis
Some cases of avascular necrosis cannot be prevented, particularly when an underlying medical condition is responsible. Risk may be reduced by avoiding excessive alcohol consumption, using corticosteroids only as medically indicated, and discussing long-term corticosteroid exposure with a healthcare professional. Prompt assessment after significant joint or bone injury may be appropriate. People with medical disorders associated with osteonecrosis may benefit from appropriate management and monitoring for complications.
Genital Herpes
Consistent condom or other barrier use can reduce, but does not completely eliminate, the risk of genital herpes transmission because uncovered skin can also transmit the virus. Avoid sexual contact when genital or oral lesions or other outbreak symptoms are present. People who know they have genital herpes should discuss the infection with partners and follow medical advice about antiviral treatment, including suppressive therapy when appropriate.

Risk Factors

Avascular Necrosis
Risk factors include prolonged or high-dose corticosteroid use, heavy alcohol consumption, previous fractures or joint trauma, and certain medical conditions affecting blood vessels or blood clotting. Associations have also been reported with disorders such as sickle cell disease, lupus, certain metabolic disorders, and some organ-transplant or cancer-related conditions. The risk varies according to the underlying cause, duration of exposure, and the location and extent of impaired blood supply.
Genital Herpes
Risk increases with sexual contact involving an infected partner, multiple sexual partners, inconsistent use of condoms or other barriers, and previous exposure to herpes simplex virus. Because transmission can occur without visible sores, a person may be exposed without knowing that a partner has an active infection. Other sexually transmitted infections or behaviors associated with increased sexual exposure can also increase risk.
