Lupus panniculitis clinically simulating alopecia areata.
A 27-year-old woman with a known history of lupus erythematosus presented with two circumscribed patches of non-scarring alopecia closely resembling alopecia areata. Scalp biopsy showed a predominantly subcutaneous and deep dermal lymphocytic infiltrate that surrounded the deep follicular segments and hair bulbs, as well as the eccrine glands. There was associated hyaline fat sclerosis. The epidermis, infundibular and isthmus segments of follicles were relatively spared and lacked the lichenoid inflammation and fibrosis seen with lupus erythematosus. The biopsy findings illustrate that the deep variant of lupus panniculitis may be concentrated around the hair bulbs and deep temporary segments of hair follicles and spare the permanent stem cell-rich follicular segments. This pattern is capable of producing a temporary hair-loss, clinically simulating alopecia areata. The clinical history, presence of subtle erythema and scalp tenderness on physical examination, as well as the biopsy findings, were important clues in distinguishing our case from a true combination of alopecia areata and lupus erythematosus.

Management of androgenetic alopecia.
Androgenetic alopecia is by far the most common cause of hair loss. It affects approximately 50% of men by the age of 50 and 20 to 53% of women by the age 50. Although it is a medically benign condition, it is a significant psychosocial issue for many patients. Various different treatment options are now available for androgenetic alopecia. The best treatment option for women with androgenetic alopecia Ludwig stage I and II is minoxidil 5% solution. If it is not effective after 1 year, antiandrogens can be tried, but there are no large studies showing their efficacy and they have considerable adverse effects. Also, for patients with alopecia that is unresponsive to treatment or with Ludwig stage III, hair transplantation can be offered if the occipital donor area is sufficient. For men, we always offer minoxidil or finasteride therapy and leave the choice of therapy to the patient. Some patients may prefer a systemic agent, whereas others may favor a topical agent. If the condition is not stabilized after 1 year or if the patient wants greater hair density, hair transplantation can be discussed. There have been tremendous advances in the treatment of hair loss in recent years and the future is very encouraging. As our knowledge of androgenetic alopecia pathophysiology increases, novel targeted treatments will potentially be developed.

Compound heterozygosity for mutations in the hairless gene causes atrichia with papular lesions.
BACKGROUND: Congenital atrichias represent a complex and heterogeneous group of genodermatoses, which have been shown in several consanguineous families to result from homozygous mutations in the hairless gene (HR). OBJECTIVES: To identify the molecular basis of congenital atrichia in a non-consanguineous family. METHODS: Genetic analysis was carried out in a two-generation family with two children with congenital atrichia and one healthy child. RESULTS: We established a diagnosis of atrichia with papular lesions based on clinical and histopathological data. We identified a heterozygous 11-bp deletion (189-199del) in the two affected children and their mother. In addition, the two affected children and their father were shown to carry a non sense mutation (Q478X), which has previously been described in a Pakistani family. Haplotype analysis revealed that mutation Q478X occurred independently in the two families. CONCLUSIONS: We have identified the first case of compound heterozygosity for mutations in HR as well as the first instance of a recurrent mutation in this gene. These data further expand our understanding of the molecular pathomechanisms underlying congenital atrichias.

Skin aging and menopause : implications for treatment.
The skin is one of the largest organs of the body, which is significantly affected by the aging process and menopause. The significant changes sustained by the skin during the menopause are due to the effect sustained on the skin's individual components.The estrogen receptor has been detected on the cellular components of the skin. Accordingly, dermal cellular metabolism is influenced by the hypoestrogenoemic state of menopause leading to changes in the collagen content, alterations in the concentration of glycoaminoglycans and most importantly the water content. Consequently changes in these basic components leads to an alteration in function compatible with skin aging.Changes in the skin collagen leads to diminished elasticity and skin strength. Collagen content may be measured by various methods such as direct skin biopsy, skin blister assessment for collagen markers and skin thickness measurement. All these variables indicate a reduction in collagen content following menopause. This may be reversed with the administration of estrogen given both topically and systemically.A reduction in hydrophilic glycoaminglycans leads to a direct reduction in water content, which influences the skin turgor. These effects on glycoaminoglycans, due to the hypoestrogenia, have been clearly shown in animal studies and appeared to be rapidly reversed with the application of estrogens. The sum total of these basic effects on the skin leads to wrinkles, the skin condition typifying skin aging.Structures resident in the skin are likewise influenced by menopause. Changes to the cutaneous vascular reactivity are noted following menopause. Capillary blood flow velocity decreases significantly in postmenopausal women. Postmenopausal flushing is due to profound vasodilatation in the dermal papillae. Hair growth is also influenced by the hormonal milieu and consequently hair loss has been associated with the beginning of menopause.Treatments administered for menopause, in particular hormone replacement therapy, appear to alter its effects on the basic components of the skin as well as the more complex structures residing in the skin, consequently retarding the skin aging process.
Seeing is believing. Learning by anecdotal observations is an old way of science.
It is not reasonable to stop taking daily food and herbal supplements altogether just because of scietific/clinical support: our life must go on until we have better understandings of food and herb. There are two merits that Hair Million enjoys: Firstly, Hair Million is relatively inexpensive, and secondly, it is made only of edible herbs that are known to be safe when consumed in regular quantities.
Propecia is a clincally validated prescription medication for hair loss.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
