Randomised controlled trial: Can topical timolol maleate prevent complications for small superficial infantile haemangiomata in high-risk areas?

BACKGROUND: To define the role of topical timolol maleate (TTM) in the treatment of infantile haemangiomata (IH). METHODS: In this single-centre randomised controlled trial, we included all <1-year-old infants within a 13-month period presenting with small (<2 cm) superficial IH located at high-risk areas (i.e. tip of ears, tip of nose, eyelids, acral areas, facial areas, scalp, neck, buttocks, perineum and axilla). Patients either received 12 months of 0.5% TTM solution (study group) or watchful waiting (control group). The primary outcome was IH with development of complications that required additional interventions. The secondary outcomes included side effects of TTM and change in IH size. RESULTS: Forty-two children were eligible to the study. Patients who received TTM were noted to have significantly fewer complications than the control group (4.2% versus 29%, odds ratio 9.58 [95% confidence interval: 1.01-91.62], p = 0.04). Mean IH volume percentage reduction was significantly more for the TTM group and no-TTM group at 3, 6 and 12 months. CONCLUSIONS: TTM is an effective and safe treatment option to reduce complications, IH volume and the need for further intervention for infants with small superficial IH located at high-risk areas. IMPACT: There is a lack of reliable signs to predict ulceration, disfigurement and other complications for high-risk IH. Treatment options range from watchful waiting to early systemic treatment, with TTM a novel and promising treatment. The exact role of TTM remains unanswered due to a lack of evidence-based research. TTM is effective and safe for infants with superficial IH of <2 cm in high-risk areas. Early TTM use on IH can reduce complications, IH volume and the need for further treatment.

Dermoscopy for common skin problems in Chinese children using a novel Hong Kong-made dermoscope.

OBJECTIVE: To evaluate the dermoscopic features of common skin problems in Chinese children. DESIGN: A case series with retrospective qualitative analysis of dermoscopic features of common skin problems in Chinese children. SETTING: A regional hospital in Hong Kong. PARTICIPANTS: Dermoscopic image database, from 1 May 2013 to 31 October 2013, of 185 Chinese children (aged 0 to 18 years). RESULTS: Dermoscopic features of common paediatric skin problems in Chinese children were identified. These features corresponded with the known dermoscopic features reported in the western medical literature. New dermoscopic features were identified in café-au-lait macules. CONCLUSION: Dermoscopic features of common skin problems in Chinese children were consistent with those reported in western medical literature. Dermoscopy has a role in managing children with skin problems.

Severe acute respiratory syndrome in children: experience in a regional hospital in Hong Kong.

OBJECTIVE: To report the clinical, laboratory, and radiologic features of children with severe acute respiratory syndrome (SARS) and to examine the difference between the younger and older age groups. DESIGN: Retrospective descriptive cohort study. SETTING: A regional hospital in Hong Kong. PATIENTS: Children younger than 18 yrs with SARS. RESULTS: Twenty-one children were included, with a mean age of 10.7 +/- 5.1 yrs. Children with SARS presented with fever, nonproductive cough, malaise, chills, headache, myalgia, and loss of appetite. Examination of the chest showed minimal auscultatory findings. Common laboratory findings included lymphopenia, thrombocytopenia, and mild elevations of activated partial thromboplastin time, alanine transaminase, lactic dehydrogenase, and creatine phosphokinase. Bacteriologic and virologic studies were all negative for common pathogens. Unilateral focal opacity was the commonest finding in chest radiography. High-resolution computerized tomography of the thorax was an early diagnostic tool if the chest radiograph was negative. The clinical course was less severe in comparison with adult patients. However, adolescents (age, > or =12 yrs) resembled adults in their clinical features. When compared with the younger age group, the adolescents had significantly higher temperatures, more constitutional upset, and a greater need for steroid treatment. Children younger than 12 yrs seemed less ill but had more coughing. On the whole, the outcome was favorable. CONCLUSION: Severe acute respiratory syndrome affects children, but the course is less severe. Nevertheless, the disease could have a significant psychosocial impact on children because of the potential seriousness of the disease in their adult family members.
