Role of the Autoimmune Regulator (AIRE) gene in alopecia areata: Strong association of a potentially functional AIRE polymorphism with alopecia universalis.

On screening the AIRE coding sequence, we identified 20 variants. Two of these at positions, G961C and T1029C, give rise to amino acid changes, S278R and V301A, located in the DNA-binding segment (SAND) and PHD1 zinc finger motif, respectively. We found no difference in the frequency of the AIRE T1029C polymorphism between the control and patient groups. We genotyped 202 alopecia areata patients and 175 matched Caucasian controls for the AIRE G961C alleles. The frequency of the rare allele (961G) was 0.08 in the controls and there was a significant increase to 0.13 in alopecia areata overall and 0.20 in severe disease (alopecia universalis). We found no association between the AIRE G961G variant and mild (patchy) alopecia areata or alopecia totalis. However, the AIRE 961G allele is a potent risk factor (> 3) for the severest form of alopecia areata, and for disease of early age at onset (at 30 years). The change from serine to arginine in the SAND domain of AIRE protein may have a significant effect on AIRE DNA-binding activity. Moreover, our results could provide a rational explanation of the unusually high frequency of AA in APECED patients, supporting the concept of AA as an autoimmune disease.

Primary follicular mucinosis: long-term follow-up of patients younger than 40 years with and without clonal T-cell receptor gene rearrangement.

Since the original descriptions of follicular mucinosis, accumulating experience shows that patient age, distribution of lesions, and duration or extent of disease do not reliably distinguish benign primary follicular mucinosis from secondary follicular mucinosis, associated with cutaneous lymphoma. More recently, it has been suggested that individuals with follicular mucinosis demonstrating a clonal T-cell receptor gene rearrangement may be at higher risk for the development of lymphoma. Long-term follow-up of 7 patients younger than 40 years with primary follicular mucinosis are reported. In all cases, there was no clinical or histologic evidence of associated dermatoses or lymphoma at the time of diagnosis. Five of the patients have clonal T-cell gene rearrangement as determined by Southern blot analysis. Clinically, at the time of diagnosis, lesions of primary follicular mucinosis ranged from papules confined to the face to widespread cutaneous plaques. After a mean follow-up of 10 years (range, 5-23 years) from the onset of disease, the majority of patients continue to have cutaneous manifestations of follicular mucinosis despite various treatments. There is no evidence of progression to cutaneous T-cell lymphoma in any patient despite the presence of a clonal T-cell receptor gene rearrangement. Continued prolonged follow-up of patients with clonal primary follicular mucinosis is necessary to determine the significance of infiltrates harboring a T-cell receptor gene rearrangement. However, in our experience with this group of selected patients, primary follicular mucinosis has been a clonal disorder with limited or "benign" cutaneous manifestations.

Dense-packing hair grafting technique for restoration of cicatricial alopecia

OBJECTIVE: To investigate the possibility of using dense-packing hair grafting technique for restoration of cicatricial alopecia. METHODS: Under local anesthesia, a scalp strip was harvested from the back of the head. A series of micro-grafts with 1-3 hairs and mini-grafts with 4-6 hairs were created from this strip. In the scarring recipient area, micro-slots were made with a 18 G needle for the micro-grafts and mini-slits were made with a No. 64 mini-blade for the mini-grafts. The grafts were then implanted into these holes. RESULTS: Ninety-six patients with 128 bald scarring areas, resulted from burn, trauma or infection, were treated with the above-mentioned technique from April. 1998 to February. 2000. All of the patients were satisfied with the appearance. In the micro-graft area, the graft density reached 10-15 mini-grafts/cm2 per session. In the micro-graft area, the graft density reached 16-19 micro-grafts/cm2 per session. Postoperative following-up for more than 1 year showed that the grafted hairs were growing well with 90%-95% survival of the hair. One third of the patients obtained satisfactory results with only one session. Two thirds of the patients needed the second session to improve the appearance. CONCLUSIONS: The dense-packing hair grafting technique is a simple, safe and effective method for hair restoration surgery. It is not only used for male pattern baldness, but could also be applied for restoration of cicatricial alopecia.

Photographic documentation of the effectiveness of 1 mg. oral finasteride in treatment of androgenic alopecia in the man in routine general practice in Switzerland

A 6-month, prospective, open, multicenter cohort study in 265 men with male pattern hair loss treated with oral finasteride 1 mg/day (Propecia) was conducted in the office of 52 Swiss dermatologists. The patient's head was placed in a stereotactic device, and Polaroid photographs were taken of the vertex and frontal areas. Endpoints used to determine treatment efficacy were patient self-assessment, investigator clinical assessment, and blinded assessment of the serial Polaroid photographs by a panel of 2 experienced dermatologists. Significant improvements were stated on the photographs by both clinical investigators and the blinded expert panel: 54% of patients showed improvement of hair growth at 6 months of treatment in the vertex region, and 48.7% in the frontal area. No progression of hair loss was found in an additional 38% (vertex) and 47% (frontal region), respectively. Clinical investigator and expert assessment yielded comparable results. Independently, patient self-assessment and investigator clinical assessment confirmed the progress. Propecia was well-tolerated, and no significant safety concerns were identified during the study. The photographic method was well accepted by the physicians. The office-based Polaroid photographic system allowed reliable assessment of change during treatment of male pattern hair loss with Propecia. The data generated in this manner corresponded to the antecedent results of the multicenter, placebo-controlled studies with oral finasteride.

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. Propecia is a clinically tested prescription medication.
