INTRODUCTION:
Since 2016, several therapies have been approved for treating atopic dermatitis (AD) in Singapore, including biologics, oral Janus kinase (JAK) inhibitors and topical crisaborole. This study supplements the 2016 Singapore treatment guidelines for AD, focusing on newer therapies for moderate-to-severe disease, while revisiting older treatment regimens to accommodate changes in knowledge and practice.
METHOD:
A modified Delphi panel was held, led by 2 co-chairs. The voting expert panel consisted of 12 dermatologists experienced in managing AD in Singapore. Delphi survey rounds were conducted between 24 July and 27 October 2023. Panellists indicated their agreement with drafted statements using a 5-point Likert scale. Consensus was defined as ≥80% agreement. An expert meeting was held to facilitate the consensus process between rounds 1 and 2 of voting.
RESULTS:
All expert panellists participated in both survey rounds, with a 100% response rate. Thirty-nine statements, classified into general principles, conventional treatments, biologics and JAK inhibitors, were proposed. Of these, 27 statements reached consensus at the end of round 1. After the expert meeting, 17 statements were included in round 2, of which 16 statements reached consensus. One statement did not reach consensus. Key updates are the inclusion of dupilumab and JAK inhibitors as potential first-line treatments for moderate-to-severe AD, in certain populations.
CONCLUSION
This modified Delphi study generated consensus among Singapore dermatology experts, to update treatment guidelines in moderate-to-severe atopic dermatitis. The consensus statements developed are intended to supplement the 2016 Singapore treatment guidelines for AD. Further revisions may be required when new evidence and/or treatments become available.

5.Approach to clinically significant vascular anomalies in children.

Vascular anomalies consist of tumours or malformations made up of abnormal growth or collections of blood vessels that can result in functional or cosmetic problems. While many vascular anomalies are present at birth, some do not appear until later in life, making diagnosis more challenging. Although many vascular anomalies are benign, some are associated with serious complications and may involve multiple organ systems. This article highlights the important features of clinically significant vascular anomalies to help physicians promptly identify and refer these cases to a specialised multidisciplinary team for evaluation and management. The discussion includes the various presenting complaints of vascular anomalies in children, namely, rapidly growing birthmarks, painful lesions, seizures/neurological manifestations, bleeding diathesis, cardiac/airway abnormalities and part of an overgrowth syndrome.

INTRODUCTION:
Infantile haemangiomas (IH) are the most common vascular tumours in childhood. Over the past decade, treatment of IH has been revolutionised by the discovery of the effectiveness of beta-blockers in its treatment. We review our hospital's experience with oral propranolol in the treatment of IH in an Asian population.
METHODS:
We performed a retrospective review of the medical records and clinical photos of paediatric patients with IH treated with propranolol in a tertiary paediatric hospital in Singapore from January 2010 to February 2015.
RESULTS:
A total of 88 patients with IH treated with propranolol were identified over a five-year period, with 79 patients included in the final analysis. There was a predominance of female patients (75.9%) and preterm infants (41.8%) in our study population. The head and neck (65.8%), especially the orbital or preorbital region (45.6%), were the most common lesion sites in our cohort of patients. Mean age of onset was 2.3 ± 4.5 weeks of age, and mean age of starting propranolol treatment was 7.7 ± 10.5 weeks of age. 44.3% of patients experienced > 75% improvement, while 29.1% experienced improvement of 50%-75%. Response to treatment was influenced by the age of starting treatment.
CONCLUSION
Our study provides further evidence of the efficacy and safety of propranolol in the treatment of IH in an Asian population. Early treatment is recommended for optimal results.

Cutaneous pseudolymphoma is an uncommon, benign lymphoproliferative disorder of the skin. Although this condition is most commonly idiopathic, its occurrence has been associated with cosmetic tattoos. We report a unique case of cutaneous pseudolymphoma that occured after accidental, traumatic inoculation of a red pigment in a healthy 33-year-old woman.

Atopic eczema is a commonly encountered chronic skin condition in primary care. In this article, we share a holistic, structured approach, which is grounded on the chronic and atopic nature of the condition - planned reviews, patient empowerment, a written action plan for chronic and fare management, and trigger avoidance. Common pitfalls in management are insufficient emphases on scheduled reviews and patient empowerment, as well as neglect in the care of the loss of the epidermal barrier during acute flares.

INTRODUCTIONRecognising and appropriately treating psychosomatic factors in dermatological conditions can have a significant positive impact on the outcomes of patients. Treatment of psychodermatological patients requires a multidisciplinary approach that involves dermatologists, psychiatrists and allied health professionals.
METHODSThis was a retrospective case series of patients seen in our psychodermatology liaison conferences from November 2009 to July 2011. We reviewed all the case notes and analysed data such as age, gender, dermatologic and psychiatric diagnoses, treatment and outcome.
RESULTSThe majority of patients in our cohort were diagnosed with either a psychophysiologic disorder or a primary psychiatric disorder. The most common diagnosis among patients with primary psychiatric disorder was delusions of parasitosis. Other common primary psychiatric disorders seen were trichotillomania and dermatitis artefacta. About a fifth of our patients had psychiatric disorders resulting from their underlying dermatological conditions. A third of our patients were lost to follow-up.
CONCLUSIONManaging patients with psychocutaneous disorders can be challenging, with many patients defaulting treatments. Psychodermatology clinics will benefit both patients and their caregivers. A collaborative approach using a consultation-liaison relationship between two medical departments in a friendly environment would result in more effective, integrated and holistic treatment strategies for such patients. Further studies should be conducted to determine how beneficial such services are to patients. With more experience, we hope to improve this service.
