Due to the multiethnic patient population with varying skin types in Singapore, clinicians often find the management of acne in their patients to be challenging. The authors developed these guidelines to provide comprehensive advice on individualized acne treatment and to provide a reference guide for all doctors who treat patients of Asian descent. Unique features of acne in Singapore are highlighted. We address concerns such as diet, special population needs, and the benefits, side effects, risks, and cost-effectiveness of currently available acne treatments. These treatment guidelines outline recommendations for the diagnosis, grading, and treatment of children, adolescents, and adults with acne of varying severity, and include advice pertaining to the use of cosmeceuticals and management of scars.

The aim of this study was to determine if the following characteristics were associated with the presence of psoriatic arthritis in a sample of psoriasis patients: race, family history of psoriasis and psoriatic arthritis, age of onset of psoriasis, smoking, alcohol consumption and the maximum body surface area (BSA) affected by psoriasis. This was a case-control study involving 400 psoriasis patients who attended the Psoriasis and Photo-medicine clinic in the National Skin Center of Singapore over a 1-year period. Cases were psoriasis patients with psoriatic arthritis while controls were psoriasis patients without psoriatic arthritis. The diagnosis of psoriatic arthritis was made by rheumatologists and participants completed a self-administered standardized questionnaire. The maximum BSA involved was determined from the case notes. Psoriatic arthritis was not significantly associated with sex, race, age of onset of psoriasis, a family history of psoriasis, smoking and alcohol consumption but was significantly associated with a family history of psoriatic arthritis (P < 0.001) and the maximum body surface involved (P = 0.05). Using multivariate analysis to control for variables, the presence of psoriatic arthritis was significantly associated with a family history of psoriatic arthritis (odds ratio [OR] = 20.5; 95% confidence interval [CI] = 2.49-169.10) and the maximum BSA involved (OR = 2.52; 95% CI = 1.33-4.75). Indian psoriatic patients were more likely to have psoriatic arthritis compared to the other races. A family history of psoriatic arthritis and a greater maximum body surface involved may be associated with having psoriatic arthritis in this study population of psoriasis patients.

The management of acne in South-East Asia is unique, as Asian skin and local variables require a clinical approach unlike that utilized in other parts of the world. There are different treatment guidelines per country in the region, and a group of leading dermatologists from these countries convened to review these guidelines, discuss current practices and recent advances, and formulate consensus guidelines to harmonize the management of acne vulgaris in the region. Emphasis has been placed on formulating recommendations to impede the development of antibiotic resistance in Propionibacterium acnes. The group adopted the Acne Consensus Conference system for grading acne severity. The group recommends that patients may be treated with topical medications including retinoids, benzoyl peroxide (BPO), salicylic acid, a combination of retinoid and BPO, or a combination of retinoids and BPO with or without antibiotics for mild acne; topical retinoid with topical BPO and a oral antibiotic for moderate acne; and oral isotretinoin if the patient fails first-line treatment (a 6- or 8-week trial of combined oral antibiotics and topical retinoids with BPO) for severe acne. Maintenance acne treatment using topical retinoids with or without BPO is recommended. To prevent the development of antibiotic resistance, topical antibiotics should not be used as monotherapy or used simultaneously with oral antibiotics. Skin care, comprised of cleansing, moisturizing and sun protection, is likewise recommended. Patient education and good communication is recommended to improve adherence, and advice should be given about the characteristics of the skin care products patients should use.

Tufted angioma is a rare, benign, vascular tumor, characterized histologically by tufts of capillary-sized vessels in the dermis. Five patients were diagnosed over a 10-year period. All developed the lesions within the first year of life. Four were Chinese and one was Indian. There was no sex predilection. All the lesions occurred on the limbs, mainly proximally, with 40% affecting the upper and 60% the lower limbs. The appearance ranged from erythematous, indurated, annular nodules to plaques. In two patients the lesions had overlying red papules, and hypertrichosis was present in three cases. The lesions were tender in all patients. No complications such as ulceration, bleeding, or Kasabach-Merritt syndrome occurred. All were treated conservatively, with improvement in tenderness in three of four patients after a period of 5 months to 4 years. Decrease in size occurred in one of four patients after 2 years. Our series differs from previous ones in that all the patients developed the lesions before the age of 1 year, all lesions occurred on the limbs, and all were tender. Tenderness and hypertrichosis, in addition to induration, may be useful in the clinical differentiation from common hemangioma.
