Current proposed mechanisms implicate both early and latent Epstein–Barr virus (EBV) infection in the carcinogenic cascade, whereas epidemiological studies have always associated nasopharyngeal carcinoma (NPC) with early child-hood EBV infection and with chronic ear, nose, and sinus conditions. Moreover, most patients with NPC present with IgA antibody titers to EBV capsid antigen (VCA-IgA), which can precede actual tumor presentation by several years. If early childhood EBV infection indeed constitutes a key event in NPC carcinogenesis, one would have to explain the inability to detect the virus in normal nasopharyngeal epithelium of patients at a high risk for EBV infection. It is perhaps possible that EBV resides within the salivary glands, instead of the epithelium, during latency. This claim is indirectly supported by observations that the East Asian phenotype shares the characteristics of an increased sus-ceptibility to NPC and immature salivary gland morphogenesis, the latter of which is inlfuenced by the association of salivary gland morphogenesis with an evolutionary variant of the human ectodysplasin receptor gene (EDAR), EDARV370A. Whether the immature salivary gland represents a more favorable nidus for EBV is uncertain, but in patients with infectious mononucleosis, EBV has been isolated in this anatomical organ. The presence of EBV-induced lymphoepitheliomas in the salivary glands and lungs further addresses the possibility of submucosal spread of the virus. Adding to the fact that the fossa of Rosen Müller contains a transformative zone active only in the ifrst decade of life, one might be tempted to speculate the possibility of an alternative carcinogenic cascade for NPC that is perhaps not dissimilar to the model of human papillomavirus and cervical cancer.

INTRODUCTIONAssertive Community Treatment (ACT) provides community-based treatment to patients with severe and persistent psychiatric illnesses, so that they may continue to live and function in the community as they receive psychiatric care. This study aimed to examine the effects of ACT on the outcome of patients over a 1-year period in an Asian population.

MATERIALS AND METHODSThis naturalistic and retrospective cohort study examined the effects of ACT on 100 patients who had completed 1 year of ACT. Parameters used to measure primary outcome were i) number of admissions (NOA) and ii) total length of stay (LOS) in days. Secondary outcome compared the employment status of patients before and after ACT. Paired sample analyses were performed using SPSS.

RESULTS AND DISCUSSIONThe mean reduction in NOA 1 year post-ACT was 57.1%. The mean reduction in LOS 1 year post-ACT was 61.9%. The median reduction for NOA and LOS were both statistically significant (P <0.01). Thirty-seven patients were employed compared to 6 before the programme, a statistically significant effect on employment (odds ratio 9.69, P <0.01).

CONCLUSIONSACT appears effective in reducing the frequency and duration of admissions for patients in Singapore. The employment status of patients also showed improvement over the course of study.

INTRODUCTIONThis study aims to describe the factors associated with surgical site infection (SSI) in elderly patients who underwent hip hemiarthroplasty following a hip fracture, in a single institution over a nine-year period.

METHODSAll patients who underwent hip hemiarthroplasty between 1 January 2004 and 31 December 2012 in our hospital were included in the present study. The detection of SSI was carried out by a trained, independent infection control nurse using the United States Centers for Disease Control and Prevention criteria. Demographic and clinical data were collected retrospectively. Demographics and clinical factors were analysed for potential associations with SSI.

RESULTSAmong the 1,320 patients who met the study inclusion criteria, a total 57 SSIs were documented, giving an infection rate of 4.3%. Patients who waited for more than one week for surgery had a statistically significantly higher risk of SSI (odds ratio 3.030, 95% confidence interval 1.075-8.545, p = 0.036). The presence of SSI was also significantly associated with increased length of hospital stay (p < 0.001). The two main microorganisms detected were methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, which accounted for 50.9% and 26.3% of the SSIs, respectively.

CONCLUSIONWe concluded that the number of days from admission to surgery is a main risk factor for the development of SSI. Steps should, therefore, be taken to prevent unnecessary delay of surgery in elderly patients requiring hip hemiarthroplasty.

INTRODUCTIONThe aims of this article were to review the role of surgical resection in the management of high-grade gliomas and to determine whether there is any survival benefit from surgical resection.

METHODSA literature review of the influence of surgical resection on outcome was carried out. Relevant original and review papers were obtained through a PubMed search using the following keywords: glioma, resection, prognosis and outcome.

RESULTSPresently, there is a lack of evidence to support a survival benefit with aggressive glioma resection, but this should not detract patients from undergoing surgery as there are many other clinical benefits of glioma excision. In addition, limiting surgical morbidity through the use of adjuvant techniques such as intraoperative magnetic resonance imaging (MRI), functional MRI and awake craniotomy is becoming increasingly important.

CONCLUSIONSIdeally, a randomised controlled trial would be the best way to resolve the issue of whether (and to what extent) surgical resection leads to improvements in patient outcome and survival, but this would not be ethical. The second best option would be well-controlled retrospective studies with a multivariate analysis of all potential confounding factors.

BACKGROUND: Standard upper blepharoplasty involves removal of both the skin and a portion of the underlying orbicularis oculi muscle. The senior author had observed sluggishness of eyelid closure, lagophthalmos as well as varying degrees of eye irritation in certain patients during the early postoperative period. He postulated that these findings could be due to orbicularis muscle excision. He therefore undertook a prospective study 27 years ago comparing standard blepharoplasty on one eyelid to skin-only excision on the fellow eyelid. METHODS: A randomized, prospective, single-blinded study was designed using the fellow eye as an internal control. 22 patients undergoing upper blepharoplasty procedure requiring greater than 5 mm of skin resection and with no history of ophthalmologic disease, dry eye, or previous eyelid surgery were selected. Upper blepharoplasty was performed with skin-only removal on one side, and combined skin-muscle removal on the other side. Patients were evaluated until six months after surgery except for two patients who were lost to follow-up after three months. Sluggish eyelid closure, lagophthalmos, dry eye and aesthetic result were outcome measures scored by patient survey, the operating surgeon, and a blinded expert panel. RESULTS: There were comparable aesthetic outcomes in both eyelids. The incidence of sluggish eyelid closure, lagophthalmos and dry eye syndrome were significantly higher in eyelids where wide segments of muscle had been resected. CONCLUSIONS: Muscle-sparing upper blepharoplasty produces similar aesthetic outcomes as conventional blepharoplasty, while significantly reducing the complications of sluggish eyelid closure, lagophthalmos and dry eye disease. The authors therefore recommend muscle-sparing upper blepharoplasty.
