A Review of the Evidence of Harm from Self-Tests

Although HIV self-testing may overcome some barriers to HIV testing, various stakeholders have expressed concerns that HIV self-testing may lead to unintended harm, including psychological, social and medical harm. Recognizing that similar concerns were raised in the past for some other self-tests, we conduct a review of the literature on a set of self-tests that share some characteristics with HIV self-tests to determine whether there is any evidence of harm. We find that although the potential for harm is discussed in the literature on self-tests, there is very little evidence that such harm occurs.     

Management of osteoarthritis of the wrist and hand

Osteoarthritis of the wrist and hand can cause significant functional impairment and disability. Its management is as much an art as it is science, as one has to consider increasing patient expectations, functional demands, pain relief and preserving motion. A sound knowledge of the wrist and hand anatomy, biomechanics, appreciation of the specific location and grade of wrist and hand joints arthritis and various treatment options and their pros and cons is important to successfully manage patients with this condition. Wrist osteoarthritis can be idiopathic, however more commonly it is secondary to distal radius and/or carpal fractures and ligamentous injuries. A small proportion still can occur due to avascular necrosis of carpus or congenital and developmental causes. Osteoarthritis of the hand is often idiopathic with a high familial tendency, especially in younger patients but can be secondary to other causes such as trauma, gout and ligamentous laxity. Once the non-surgical management options such as analgesia, activity modifications, steroid injections and splints have been exhausted, then there are various surgical options available for wrist and hand osteoarthritis. These are tailored to the exact location of arthritis and patient factors. For the wrist, these include anterior and posterior interosseous nerve neurectomy, arthroscopic debridement, selective bony excisions, wrist arthroplasty and focal or total fusion. Whilst for finger osteoarthritis, surgical options include arthroplasty and arthrodesis. This article aims to describe the pathology of wrist and hand arthritis and various treatment options available.
