Alopecia areata - Wikipedia. Alopecia areata, also known as spot baldness, is an autoimmune disease in which hair is lost from some or all areas of the body, usually from the scalp, due to the body's failure to recognize its own body cells and subsequent destruction of its own tissue. What Doctors Don’t Tell You About Acne. Modern medicine considers mild to moderate acne an acceptable feature of growing up. If you go to your doctor for help with. In 1–2% of cases, the condition can spread to the entire scalp (alopecia totalis) or to the entire skin (alopecia universalis). There are two types: (1) scarring alopecia, where there is fibrosis, inflammation, and loss of hair follicles, and (2) nonscarring alopecia, where the hair shafts are gone but the hair follicles are preserved, making this type of alopecia reversible. The underlying skin is unscarred and looks superficially normal. Although these patches can take many shapes, they are usually round or oval. The disease may also go into remission for a time, or may be permanent. It is common in children. The area of hair loss may tingle or be painful. In cases of alopecia areata, hair will tend to pull out more easily along the edge of the patch where the follicles are already being attacked by the body's immune system than away from the patch where they are still healthy. A few cases of babies being born with congenital alopecia areata have been reported. This study identified at least four regions in the genome that are likely to contain these genes. The genes that were identified include those involved in controlling the activation and proliferation of regulatory T cells, cytotoxic T lymphocyte- associated antigen 4, interleukin- 2, interleukin- 2 receptor A, and Eos (also known as Ikaros family zinc finger 4), as well as the human leukocyte antigen. The study also identified two genes, PRDX5 and STX1. In alopecia areata, trichoscopy shows regularly distributed . Histologic findings include peribulbarlymphocytic infiltrate (. Occasionally, in inactive alopecia areata, no inflammatory infiltrates are found. Other helpful findings include pigment incontinence in the hair bulb and follicularstelae, and a shift in the anagen- to- telogen ratio towards telogen. It may occur anywhere on the head.
Alopecia areata multilocularis refers to multiple areas of hair loss. Ophiasis refers to hair loss in the shape of a wave at the circumference of the head. The disease may be limited only to the beard, in which case it is called alopecia areata barbae. The cream is not as effective and it takes longer in order to see results. Steroid injections are commonly used in sites where the areas of hair loss on the head are small or especially where eyebrow hair has been lost. Whether they are effective is uncertain. Some other medications that have been used are minoxidil, Elocon (mometasone) ointment (steroid cream), irritants (anthralin or topical coal tar), and topical immunotherapy ciclosporin, sometimes in different combinations. Topical corticosteroids frequently fail to enter the skin deeply enough to affect the hair bulbs, which are the treatment target. Oral corticosteroids decrease the hair loss, but only for the period during which they are taken, and these drugs can cause serious side effects. Loss of hair also means the scalp burns more easily in the sun. Patients may also have aberrant nail formation because keratin forms both hair and nails. Hair may grow back and then fall out again later. This may not indicate a recurrence of the condition, but rather a natural cycle of growth- and- shedding from a relatively synchronised start; such a pattern will fade over time. Episodes of alopecia areata before puberty predispose to chronic recurrence of the condition. Because hair loss can lead to significant changes in appearance, individuals with it may experience social phobia, anxiety, and depression. Alopecia areata occurs in people who are otherwise healthy and have no other skin disorders. Elston (2. 00. 6). Andrews' diseases of the skin: clinical dermatology. Saunders Elsevier.
