The pattern and profile of alopecia areata in Singapore - a study of 219 Asians.

BACKGROUND: Alopecia areata is believed to be an autoimmune condition with a worldwide occurrence. It usually presents as patchy, nonscarring hair loss. There is a paucity of clinical data in Asians. OBJECTIVE: To study the epidemiology, clinical aspects, associations, and treatment of alopecia areata in an Asian population over a 1-year period. METHODS: Records of all newly diagnosed alopecia areata cases seen from May 1998 to April 1999 at the National Skin Center were collated with regard to the epidemiology, pattern of alopecia, and associations according to the investigational guidelines published by Oslen et al. The treatment and psychologic impact of alopecia areata were also assessed. RESULTS: Two hundred and nineteen new case referrals of alopecia areata were seen from May 1998 to April 1999. The incidence of alopecia areata was 3.8%. There were 173 Chinese (79%), 35 Indians (16%), and 11 Malays (5.0%). The male to female ratio was 1 : 1.3. The median age at presentation was 25.2 years. The majority of patients (85.5%) had their first episode of alopecia areata before the age of 40 years. Of the patients with onset of alopecia areata before the age of 40 years, 36.5% presented with extensive alopecia, compared with 5.5% above the age of 40 years (P < 0.05). Nail changes, consisting of pitting, trachyonychia, and longitudinal ridging, were reported in 23 patients (10.5%). A significant percentage of patients had an associated personal and family history of atopy (60.7%). There was no significant association between a personal history of atopy and the extent of alopecia areata. The frequencies reported for the following associated diseases were: thyroid disease, 2.3%; vitiligo, 4.1%; diabetes mellitus, 3.2%; Down's syndrome, 1.4%; and rheumatic arthritis, 0.9%. A family history of alopecia areata was reported in 4.6%. Intralesional triamcinolone acetonide was the first-line treatment for limited alopecia areata, while squaric acid dibutyl ester was used for extensive involvement. The majority of patients with limited alopecia areata (82.1%) had more than 50% improvement with intralesional triamcinolone acetonide after 3 months. The majority of patients who received squaric acid dibutyl ester (87.5%) achieved more than 50% regrowth at the end of 6 months. Poor prognostic factors for alopecia areata were extensive involvement, early age of onset, and Down's syndrome. Thirteen out of 132 respondents (9.8%) recalled stressful events preceding hair loss. Patients with extensive alopecia areata experienced more psychologic adverse effects than those with limited alopecia areata (P < 0.05). Males with extensive alopecia areata experienced more severe psychologic ill-effects, such as depression and feelings of inability to improve hair loss. CONCLUSIONS: Our findings are similar to those reported in the Western literature where alopecia areata is predominantly a disease of the young. A holistic approach is important in the management of alopecia areata as the disease can have a severe psychologic impact on an individual's well-being.

Alopecia universalis in a case of systemic lupus erythematosus.

We report a case of systemic lupus erythematosus (SLE) who presented with alopecia universalis. MR, a 23 years female patient was admitted with alopecia universalis and other features of SLE like peripheral arthritis, fever, nephritis, butterfly rash over the malar regions, positive ANA and anti-ds DNA antibodies. There was a gap of four years between the onset of alopecia universalis and other clinical features of SLE. The alopecia was of non-scarry variety and responded to systemic and topical steroids.

The art of repair in surgical hair restoration--part II: the tactics of repair.

BACKGROUND: As patient awareness of new hair transplantation techniques grows, the repair of improperly planned or poorly executed procedures becomes an increasingly important part of surgical hair restoration. OBJECTIVE: Part II of this series is written to serve as a practical guide for surgeons who perform repairs in their daily practices. It focuses on specific repair techniques. METHODS: The repairs are performed by excision with reimplantation and/or by camouflage. Follicular unit transplantation is used for the restorative aspects of the procedure. RESULTS: Using punch or linear excision techniques allows the surgeon to relocate poorly planted grafts to areas that are more appropriate. The key elements of camouflage include creating a deep zone of follicular units, angling grafts in their natural direction, and using forward and side weighting of grafts to increase the appearance of fullness. In special situations, removal of grafts without reimplantation can be accomplished using lasers or electrolysis. CONCLUSION: Meticulous surgical techniques and optimal utilization of a limited hair supply will enable the surgeon to achieve the best possible cosmetic results for patients requiring repairs

Toe tourniquet syndrome in association with maternal hair loss.

Increased hair loss a few months after delivering an infant is a common postpartum condition known as telogen effluvium. A much less common condition involving young infants is the hair-thread tourniquet syndrome, or toe tourniquet syndrome, which involves hair or thread becoming so tightly wrapped around an appendage that pain, injury, and sometimes loss of the appendage result. This case report is the first known description of the hair-thread tourniquet syndrome in association with maternal telogen effluvium. A literature review shows that accidental cases involving human hair almost always involve the toes, and usually occur at the age when mothers are experiencing excessive hair loss. This association is significant in that anticipatory guidance of new parents experiencing rapid hair loss may prevent cases of the toe tourniquet syndrome and its associated morbidity.
