Striae distensae - like lesions. A cause of scarring alopecia among children.
OBJECTIVE: Although alopecia areata is a common problem among children, many misdiagnoses for this condition can happen. The aim of this study was to demonstrate the striae distensae as lesions that cause scarring alopecia with a great resemblance to alopecia areata. METHODS: A total of 36 children with provisional diagnosis of alopecia areata of the scalp were assessed clinically in the Department of Dermatology and Venereology, Baghdad Teaching Hospital, Baghdad, Iraq, between June 1998 to June 2001. Their age ranged from 3 12 years and the mean + standard deviation (SD) was 7.30 + 2.59 years with equal sex ratio. RESULTS: All patients provided for this study had a history of patchy hair loss of few months duration. Their parents denied any history of obvious trauma and many modalities of treatment had been tried without benefit. The clinical examination revealed single or multiple (1-6) (mean + SD 2.41 + 1.22) complete linear hair loss patches resembling atrophic scar that was similar to striae distensae. The histopathological examination showed atrophy of the epidermis, full replacement of the dermis by collagen bundles, and complete loss of appendages. CONCLUSION: This is a new entity, which seems to be common among children and often confused with untreated cases of alopecia areata. This condition should be added to the differential diagnosis of patchy hair loss in children and the parents should be reassured of the cause of hair loss and no treatment therapy needed.

Relationship between irreversible alopecia and exposure to cyclophosphamide, thiotepa and carboplatin (CTC) in high-dose chemotherapy.
Reversible alopecia is a commonly observed, important and distressing complication of chemotherapy. Permanent alopecia, however, is rare after standard-dose therapy, but has occasionally been observed after high-dose chemotherapy with cyclophosphamide, thiotepa and carboplatin (CTC). We evaluated the relationships between total exposure to these three compounds and their different metabolites in the high-dose CTC regimen, and the subsequent development of irreversible alopecia. Twenty-four patients received two or three courses of high-dose CTC, each followed by peripheral blood progenitor cell transplantation. Plasma levels of cyclophosphamide, its active metabolite 4-hydroxycyclophosphamide, thiotepa, its active metabolite tepa, and carboplatin were determined, and the area-under-the-plasma concentration-versus-time curves (AUC) of the compounds were calculated. Eight of the 24 patients included in the study developed permanent alopecia, while seven had normal hair regrowth and nine patients developed incomplete and/or thin hair regrowth. The carboplatin AUC and the summed AUC of thiotepa and tepa were both significantly associated with increasing irreversibility of hair loss. These results suggest that high exposure to carboplatin and the sum of the thiotepa and tepa exposure may lead to the development of permanent alopecia. This knowledge could guide therapeutic drug monitoring in order to prevent the occurrence of permanent alopecia and thereby improve the patients' quality of life.

Interleukin-1 receptor antagonist allele 2 and familial alopecia areata.
Alopecia areata affects 1%-2% of the population and is hypothesized to be an autoimmune, organ specific T-cell mediated reaction directed against the human hair follicle. It is characterized by loss of hair in patches (alopecia areata) with progression in some individuals to total loss of scalp hair (alopecia totalis) or to loss of all scalp and body hair (alopecia universalis). The interleukin-1 receptor antagonist (IL-1RN) gene was found to be associated with more severe clinical outcome in several chronic inflammatory diseases, including alopecia areata. The IL-1RN*2 allele was found to be associated with alopecia areata severity in a British case-control study. In this paper, we analyzed alopecia areata probands in a family-based sample (n = 131 parent-offspring trios) to study the association between alleles of the IL-1RN and various phenotypes of alopecia areata. In considering all patients with any form of alopecia areata, no association was found with IL-1RN. IL-1RN*2 allele was not associated with alopecia totalis and alopecia universalis. A borderline association was observed between IL-1RN and patchy alopecia areata but it was not statistically significant (p =0.06). We also observed an association between IL1-RN*1 allele and patchy alopecia areata (p =0.045).

Cutaneous side effects of interferons
The alpha, beta and gamma recombinant interferons are indicated in a growing spectrum of therapeutic indications. Some unwanted side effects occur on the skin. The main clinical presentations include vesiculo-bullous sometimes infiltrated dermatitis, vasculitis, necrosis, ulceration and alopecia. Exacerbation of dermatoses such as psoriasis is also possible.
Since hair growth is a complicated biological process, modern science has yet to grasp a complete picture. A number of traditional and alternative therapeutic methods that include drugs, surgery, and suppelements have been developed to help those who are losing hair. Unfortunately, none of these approaches are perfect for all hair loss problems due to the complexity of the phenomenon and diverse nature of the causes underlying hair loss. Also, most of chemical drugs and hair transplantation surgeries are accompanied by undesirable side effects.
DreamPharm offers Hair Million (have you heard?) to help treat hair loss problems. Numerous anecdotal cases have demonstrated that this herbal formula based on traditional Chinese herbs actually improves hair thinning and hair loss, a condition often associated with aging, for a significant fraction of people who take the formula regularly. It is not yet understood how Hair Million can stop hair loss and promote hair growth. No scientific research or placebo controlled clinical analysis has been performed on these herbs. Lack of scientific/clinical research is not uncommon in herbal arena. Nonetheless, there are two merits in this hair restoration herbal formula: Firstly, Hair Million is relatively inexpensive, and secondly, it is made of edible herbs that are known to be safe when consumed in regular quantities. Buy Propecia Online is a clinically tested prescription medication.
