ABSTRACT
Allergic rhinitis (AR) is prevalent in Singapore, with a significant disease burden. Afflicting up to 13% of the population, AR impairs quality of life, leads to reduced work productivity and is an independent risk factor for asthma. In the last 2 decades, local studies have identified patient and physician behaviours leading to suboptimal control of the disease. Yet, there is an overall lack of attention to address this important health issue. Allergic Rhinitis and its Impact on Asthma (ARIA) is a European organisation aimed at implementing evidence-based management for AR worldwide. Recent focus in Europe has been directed towards empowering patients for self-management, exploring the complementary role of mobile health, and establishing healthcare system-based integrated care pathways. Consolidation of these ongoing efforts has led to the release of the 2019 ARIA care pathways. This review summarises the ARIA update with particular emphasis on the current status of adult AR in Singapore. In addition, we identify unmet needs and future opportunities for research and clinical care of AR in the local context.
ABSTRACT
<p><b>BACKGROUND</b>Nasopharyngeal carcinoma (NPC) patients have a 19%-56% locoregional recurrence rate after primary therapy. For those recurrent NPC (rNPC) patients, re-irradiation may cause some complications. In recent years, endoscopic endonasal nasopharyngectomy (EEN) has become a surgical option for rNPC patients. Here we introduce the concept of en bloc excision (EBE) technique for EEN, including the surgical technique and clinical outcomes.</p><p><b>METHODS</b>A retrospective study was conducted covering September 2009 to May 2013, involving the collection of locoregional rNPC cases from two institutions (Kuang-Tien General Hospital (KTGH) in Taiwan and National University Health System (NUHS) in Singapore). These patients failed prior therapy and then underwent EEN. We reported the 2-year overall survival rate, the 2-year disease-free survival rate, and related complications.</p><p><b>RESULTS</b>Nine patients (five from KTGH and four from NUHS) completed this study, with five, two, and two patients of recurrence tumors (rT1), rT2, and rT3, respectively. The mean age was 46.4 years (range 32-63); the mean follow-up period was 24.9 months (range 10-45). The 2-year survival rate and the 2-year disease-free rate were 100% and 80%, respectively, in five patients. No significant complications or cases of mortality occurred.</p><p><b>CONCLUSIONS</b>The EBE concept of EEN is suitable for early rT1 and has relatively encouraging short-term outcomes. In selected rT2, careful EBE can be performed by expanding the surgical field. A clear view of the internal carotid artery-related anatomy is indispensable. In the future, more series may be needed to determine the role of EEN in rNPC patients.</p>
