Abstract
Eight primary embryonic developmental stages were assigned to eggs of ballan wrasse Labrus bergylta using key morphological features following standardized nomenclature: Ia, Ib, II, III, IV, V, VI and VI+, reared from single family clutches under comparable environmental conditions in Ireland and Norway. Development in L. bergylta is typical of demersal marine finfish species with a short egg stage. Hatching occurred c. 123 h post-fertilization (hpf) equivalent to 62·5 degree days at 12·2 ± 1·10° C (mean ±S.D.), after which the larvae swam intermittently near the surface of the water column.

Abstract
Immunoglobulin (Ig)G levels are important for antibody vaccine responses and IgG subclass deficiencies have been associated with severe 2009 influenza A (H1N1) infections. Studies have demonstrated variations in immune responses to the H1N1 vaccine, but the aetiology of this is unknown. We determined the associations between pre-vaccination overall and influenza-specific IgG subclass levels and 2009 H1N1-specific antibody responses post-vaccination (robust versus poor at day 28) stratified by human immunodeficiency virus (HIV) status. Logistic regression models were utilized to evaluate whether pre-vaccination IgG subclass levels were associated with the antibody response generated post-vaccination. We evaluated 48 participants as part of a clinical study who were stratified by robust versus poor post-vaccination immune responses. Participants had a median age of 35 years; 92% were male and 44% were Caucasian. HIV-infected adults had a median CD4 count of 669 cells/mm(3) , and 79% were receiving highly active anti-retroviral therapy. HIV-infected participants were more likely to have IgG2 deficiency (<240 mg/dl) than HIV-uninfected individuals (62% versus 4%, P < 0·001). No association of pre-vaccination IgG subclass levels (total or influenza-specific) and the antibody response generated by HIN1 vaccination in either group was found. In summary, pre-vaccination IgG subclass levels did not correlate with the ability to develop robust antibody responses to the 2009 influenza A (H1N1) monovalent vaccine. IgG2 deficiencies were common among HIV-infected individuals but did not correlate with poor influenza vaccine responses. Further investigations into the aetiology of disparate vaccine responses are needed.

Abstract
OBJECTIVES To compare a mandibular advancement splint to a control bite raising appliance in the treatment of snoring with or without mild obstructive sleep apnoea syndrome. DESIGN A prospective two-treatment randomised cross-over clinical trial. SETTING Single centre secondary care Dental Hospital. PARTICIPANTS Fifty-two subjects (36 men, 16 women) diagnosed with non-apnoeic snoring or mild obstructive sleep apnoea syndrome (apnoea/hypopnoea index < or =15 events/h), were recruited from Departments of Respiratory Medicine and ENT surgery, Newcastle upon Tyne Hospitals NHS Foundation Trust. MAIN OUTCOME MEASURES The Snoring Symptoms Inventory questionnaire (SSI) and the Epworth Sleepiness Score (ESS) were used to evaluate changes in symptoms. Patient reported outcomes (compliance, adverse events, splint preference) were recorded by questionnaire. Subjects attended for five study visits and used a mandibular advancement splint and a bite raising appliance at home each for 4 weeks, with a 3-week washout period between devices. RESULTS AND CONCLUSIONS Thirty-eight subjects completed the study. Both the mandibular advancement splint and bite raising appliance significantly reduced the SSI compared to the baseline scores: mandibular advancement splint 5.5, P = 0.013; bite raising appliance 3.1, P = 0.005. No statistically significant difference between the two treatment periods was detected (P > 0.05). The reduction in the Epworth Sleepiness Score was: mandibular advancement splint 1.0, P = 0.02; bite raising appliance 0.3, P = 0.4. The change in the Epworth Sleepiness Score was not statistically significantly different between the mandibular advancement splint and bite raising appliance treatment periods (P > 0.05). CONCLUSIONS In this cohort of patients diagnosed with snoring +/- mild OSA: 1 both the mandibular advancement splint and bite raising appliance designs of splint appeared to reduce the symptoms of snoring; 2 no difference in the magnitude of this effect was detected in favour of one design of splint.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of a topical hyaluronic acid (HA) gel preparation (0.2%) in the management of oral lichen planus (OLP). METHODS A total of 124 patients with erosive OLP participated in a randomized, placebo-controlled, double-blind trial to evaluate the efficacy of a topical HA preparation. Outcome measures included soreness relief following immediate application, oral function and size of erosive/ulcerative area. Patients were medicated for 28 days and completed a log diary recording oral function and soreness scores. RESULTS Application of topical HA produced a significant reduction (P < 0.05) in soreness scores when compared with placebo for up to 4 h post-application. There was no difference between treatment groups (P > 0.05) with respect to oral function. Patients treated with 0.2% HA showed a significant reduction (P < 0.05) in the size of the erosive/ulcerated area after 28 days of treatment when compared with baseline. There was no significant difference in changes in ulcerative areas between treatment groups. CONCLUSIONS Topical HA (0.2%) does appear to be of some benefit in the management of erosive lichen planus providing efficacy for up to 4 h after administration. Very frequent applications should be considered to obtain a more significant clinical benefit. Topical HA gel may be a useful addition to the treatment option for OLP.

Abstract
BACKGROUND Oligodendroglial neoplasms have morphologic and genotypic heterogeneity. Loss of heterozygosity (LOH) of 1p and/or 19q is associated with increased treatment responsiveness and overall survival. However, the pathogenesis of treatment-resistance is unknown. We sought to determine if tumour progression is due to a proliferating sub-population of tumour cells with intact 1p, or if recurrent tumours retain 1p/19q LOH. METHODS 24 patients with oligodendroglial neoplasms, possessing biopsy samples taken at diagnosis and at progression, were identified. 53 tumour specimens were available for LOH analysis of 1p and 19q, using PCR amplification of multiple microsatellite markers. 40 were also tested for 9p and 10q. RESULTS At diagnosis, the median age was 34 (24-66) years, 14 were male. 19 tumours were WHO Grade II, and 5 were high grade. The most common genomic status was 19q LOH (70%). 13 (54%) tumours were 1p LOH at diagnosis: of these, 12 were 19q LOH, and 1 was 19q uninformative. All 12 patients with 1p/19q LOH primary tumours had persistent co-deletion at progression. 9 (38%) tumours were 1p intact at diagnosis, and 8 remained 1p intact in the progressed tumours. There was little heterogeneity of 9p and 10q between tumours at diagnosis and progression. CONCLUSION 100% of oligodendroglial tumours with 1p/19q LOH, demonstrated persistent 1p/19q LOH in the progressed tumour. Therefore, progression of these tumours is not due to a proliferating sub-population of treatment-resistant, 1p intact tumour cells. We propose that additional mutations contribute to this aggressive phenotype, however, 9p LOH or 10q LOH are unlikely to be involved.

Abstract
AIMS To review the epidemiology, diagnosis and changing treatment paradigm of ocular candidiasis, and report current prevalence rates and risk factors at one inpatient hospital. DESIGN Retrospective review; systematic literature review. METHODS All Wills Eye Institute inpatient ophthalmology consultations from Thomas Jefferson University Hospital were retrospectively reviewed between June 2006 and November 2006. All consultations for candidaemia were included. The outcome variables included chorioretinitis, endophthalmitis, visual symptoms and Candida speciation. The ophthalmic literature was reviewed using PubMed. Keywords included Candida, candidaemia, chorioretinitis, vitritis and endophthalmitis. Bibliographies were manually searched. RESULTS Three of the 38 consultations for candidaemia (7.9%) had chorioretinitis. There were no cases of vitritis or endophthalmitis. The presence of symptoms, or the inability to articulate symptoms, was significantly associated with risk of ocular candidiasis (p = 0.003). All three cases of chorioretinitis had positive blood cultures for Candida albicans (p = 0.089) and were treated with oral fluconazole. CONCLUSIONS Various factors have led to the increasing prevalence of inpatient candidaemia. Risk factors for ocular involvement include albicans species and the presence of, or inability to articulate, visual symptoms. For those without abnormal findings on initial examination, a subsequent retinal examination should be performed in 2 weeks, particularly if new symptoms develop or if the patient is unable to relay symptoms. Patients with chorioretinitis should be treated with systemic antifungal agents. For those with vitritis or endophthalmitis, particularly if worsening on systemic therapy alone, intravitreal antifungal medications or early vitrectomy should be considered.

Abstract
From 1998 to 2001 we examined spatial and temporal variation in uptake of contaminants by surf scoters (Melanitta perspicillata) in the Georgia Basin region of the Pacific coast of Canada. Samples were collected during late fall and early spring at industrialized and reference locations, carcasses examined, and tissues collected for histology, biomarkers, and contaminant analyses. Scoters from both Vancouver and Victoria harbours had significantly higher hepatic concentrations of summation operatorbutyltins than birds from a reference site. In adult male surf scoters, hepatic summation operatorbutyltins increased over the winter at two sites (p=0.02, n=26), while mercury increased (p=0.03, n=15) and selenium decreased at one site (p=0.001, n=15). Body condition decreased over the winter at both the treatment site, Howe Sound (p<0.0001, n=12), and the reference site, Baynes Sound (p=0.02, n=15). Multiple regression analysis using Akaike's Information Criteria (AIC(C)) showed an association between hepatic butyltin concentrations and overall body condition (p=0.06, r=-0.237).

Abstract
10577 Background: There is morphologic and genotypic heterogeneity of oligodendroglial neoplasms. Tumors with loss of heterozygosity (LOH) of 1p and/or 19q are associated with increased chemo-sensitivity and survival. Despite treatment, rates of recurrence and malignant transformation are high. The pathogenesis of treatment-resistance is unknown. We aim to determine if tumour progression is associated with a proliferation of clonagens with retention of heterozygosity (ROH) of 1p, or if progressing tumours remain 1p/19q LOH. Methods: Between 1/1/2001 and 7/31/2006, 24 patients with oligodendroglial neoplasms, and possessing serial biopsies taken at diagnosis and at progression, were identified. Using PCR amplification of multiple microsatellite markers, a total of 53 tumour specimens were available for LOH analysis of 1p and 19q; 40 were also tested for 9p and 10q. Results: At diagnosis, the median age was 34 (24–66) years and 14 were male. Using the WHO criteria, 19 tumors were Grade II oligodendrogliomas or oligoastrocytomas, and 5 were high grade. The most common genomic status was 19q LOH (88%); 54% had 1p LOH. Of the 13 primary biopsies with 1p LOH, 11 had 19q LOH, 1 had 19q ROH, and 1 was 19q non-informative. A further 2 primaries were mixed 1p LOH/ROH, and 9 were 1p ROH. At progression, 10 of 11 patients with 1p/19q LOH had persistent co-deletion. The patient with 1p LOH and 19q ROH at diagnosis, had 1p/19q LOH at progression. Of the mixed 1p primaries, 1 was 1p ROH, and the other remained mixed LOH/ROH at progression. 8 of 9 primaries with 1p ROH remained 1p ROH. There was also little heterogeneity of 9p and 10q between primary and progressive tumours. Using Kaplain-Meier analysis, mean overall survival (OS) for the group was 102 (95% CI: 77–127) months. Mean progression-free survival was 52 (95% CI: 33–72) months. OS was not statistically significant between patients with 1p LOH and 1p ROH primary tumours. Conclusions: 91% of repeat biopsies of oligodendroglial tumors, demonstrated persistent 1p/19q LOH. Therefore, progression of 1p/19q LOH primary tumours is not due to a proliferating sub-group of chemo-resistant, 1p ROH clonagens. We propose that additional mutations contribute to this aggressive phenotype. No significant financial relationships to disclose.
