Lymphatic malformations (LMs) are one of the more commonly encountered cystic head-and-neck tumors. Surgical excision is the traditional treatment with inherent perioperative risks. Alternative treatment of these tumors using percutaneous sclerotherapy agents has been proposed with no major consensus on the treatment approaches and sclerotherapy agent choices. This paper presents a systematic review of percutaneous ethanol sclerotherapy for neck lymphangioma and a case report of ethanol ablation in a patient with neck lymphangioma with good cosmesis results. Systematic review was conducted on PubMed using key words: “Ethanol” OR “Alcohol” AND “Ablation” OR “Sclerotherapy” OR “Sclerosing” AND “Lymphangioma” OR “Lymphatic Malformation” as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Three hundred fifteen articles from initial PubMed search results were screened by titles and abstracts. Full text was retrieved. 3 studies were included in our systematic review. Overall evidence quality is modest with marked heterogeneity. All 12 patients treated with percutaneous ethanol sclerotherapy for head-and-neck LMs reported favorable response. Only 1 patient (8.3%) encountered a peri-procedural complication. Percutaneous ethanol sclerotherapy of neck lymphangioma in our patient also reported favorable response with no complications. Invasive treatment for LMs should be personalized and dependent on the availability of experienced operators/ centers with appropriate volume in either primary excisional surgery or percutaneous sclerotherapy. Percutaneous ethanol sclerotherapy is an acceptable option with benefits of widespread availability and cost-effectiveness in our South-East Asia region. Limitations of our review are largely due to significant study heterogeneity.

Non-compliance to hygienic practices in contact lens wear is regarded as a significant risk factor for contact lens-related complications. Non-compliant behaviour continues to prevent efforts to improve contact lens safety despite advancements in lens materials and care solutions. The objective of this study was to identify the association between knowledge, compliance and complications of contact lens wear. A cross-sectional design was used and contact lens users among medical faculty students were identified and recruited via convenience sampling throughout October 2013 to March 2014. A total of 36 close-ended questions that focused on knowledge level, compliance to standard contact lens practice, and experience of complications were administered. A total of 188 respondents, majority of females (89.4%; n=168) participated in this study. Although majority had good knowledge level (68.1%; n=128) on care and usage of contact lens while only a small number having moderate knowledge (26.6%; n=50) and poor knowledge (5.3%; n=10), most of them were partially compliant (74.5%; n=140) to the recommended contact lens practices. However, a small group was found to be fully compliant (24.4%; n=46) and the rest being non-compliant (1.1%; n=2). There was a significant association between knowledge on contact lens usage and compliance level to standard practices (p=0.0003). In addition, a significant association also existed between compliance level to recommended practices and risk of complications from contact lens usage (p=0.023). Findings of this study showed the positive association between knowledge of contact lens usage and compliance to recommended practices and negative association between knowledge of contact lens usage and complications experienced by contact lens users. By providing basic knowledge on contact lens care and usage via education, improvement on compliance and enhancement of safety of contact lens wear could invariably be achieved.
