Abstract
Doege-Potter syndrome is a rare paraneoplastic syndrome presenting as a hypoinsulinaemic hypoglycaemia from the ectopic secretion of a prohormone of insulin-like growth factor II (IGF-II) from a solitary fibrous tumour. Surgical resection is curative in the majority of cases. If, however, the diagnosis is not suspected and treatment is delayed, it can lead to hypoxic cerebral injury or death. The underlying tumour can be a benign or malignant pleural tumour but may be present in extrapleural sites. For a diagnosis of Doege-Potter syndrome, symptoms attributable to hypoglycaemia and low blood glucose levels should be present along with the secretion of prohormone IGF-II. We report a case of severe hypoglycaemia in a 76-year-old inpatient admitted for resection of a recurrent left-sided pleural tumour. Investigation revealed true hypoglycaemia and Doege-Potter syndrome was diagnosed. The tumour was completely resected and the patient made a full recovery with no further hypoglycaemic episodes.

Seasonal variation in month of diagnosis in children with type 1 diabetes registered in 23 European centers during 1989-2008: little short-term influence of sunshine hours or average temperature. Pediatr Diabetes 2015; 16:573-80.

Abstract
BACKGROUND The month of diagnosis in childhood type 1 diabetes shows seasonal variation. OBJECTIVE We describe the pattern and investigate if year-to-year irregularities are associated with meteorological factors using data from 50 000 children diagnosed under the age of 15 yr in 23 population-based European registries during 1989-2008. METHODS Tests for seasonal variation in monthly counts aggregated over the 20 yr period were performed. Time series regression was used to investigate if sunshine hour and average temperature data were predictive of the 240 monthly diagnosis counts after taking account of seasonality and long term trends. RESULTS Significant sinusoidal pattern was evident in all but two small centers with peaks in November to February and relative amplitudes ranging from ± 11 to ± 38% (median ± 17%). However, most centers showed significant departures from a sinusoidal pattern. Pooling results over centers, there was significant seasonal variation in each age-group at diagnosis, with least seasonal variation in those under 5 yr. Boys showed greater seasonal variation than girls, particularly those aged 10-14 yr. There were no differences in seasonal pattern between four 5-yr sub-periods. Departures from the sinusoidal trend in monthly diagnoses in the period were significantly associated with deviations from the norm in average temperature (0.8% reduction in diagnoses per 1 °C excess) but not with sunshine hours. CONCLUSIONS Seasonality was consistently apparent throughout the period in all age-groups and both sexes, but girls and the under 5 s showed less marked variation. Neither sunshine hour nor average temperature data contributed in any substantial way to explaining departures from the sinusoidal pattern.

Abstract
A pattern of excessive hip adduction and internal rotation with medial deviation of the knee has been associated with numerous musculo-skeletal dysfunctions. Research into the role that ankle dorsiflexion (DF) range of motion (ROM) play in lower limb kinematics is lacking. The objective of this cross-sectional, observational study was to investigate the relationship between ankle DF ROM, and hip adduction and hip internal rotation during a step-down test with and without heel elevation in a healthy female population. Hip and ankle ROM was measured kinematically using a ten-camera Optitrack motion analysis system. Thirty healthy female participants (mean age = 20.4 years; SD = 0.9 years) first performed a step-down test with the heel of the weight bearing foot flat on the step and then with the heel elevated on a platform. Ankle DF, hip adduction and hip internal rotation were measured kinematically for the supporting leg. Participants who had 17° or less of ankle DF ROM displayed significantly more hip adduction ROM (p = 0.001; Cohen's d effect size = 1.2) than the participants with more than 17° of DF during the step-down test. Participants with limited DF ROM showed a significant reduction in hip adduction ROM during the elevated-heel step-down test (p = 0.008). Hip internal rotation increased in both groups during the EHSD compared to the step-down test (p > 0.05) Reduced ankle DF ROM is associated with increased hip adduction utilised during the step-down test. Ankle DF should be taken into account when assessing patients with aberrant frontal plane lower limb alignment.

Abstract
The production of neutron beams having short temporal duration is studied using ultraintense laser pulses. Laser-accelerated protons are spectrally filtered using a laser-triggered microlens to produce a short duration neutron pulse via nuclear reactions induced in a converter material (LiF). This produces a ∼3 ns duration neutron pulse with 10(4) n/MeV/sr/shot at 0.56 m from the laser-irradiated proton source. The large spatial separation between the neutron production and the proton source allows for shielding from the copious and undesirable radiation resulting from the laser-plasma interaction. This neutron pulse compares favorably to the duration of conventional accelerator sources and should scale up with, present and future, higher energy laser facilities to produce brighter and shorter neutron beams for ultrafast probing of dense materials.

Abstract
Calibration of three scintillators (EJ232Q, BC422Q, and EJ410) in a time-of-flight arrangement using a laser drive-neutron source is presented. The three plastic scintillator detectors were calibrated with gamma insensitive bubble detector spectrometers, which were absolutely calibrated over a wide range of neutron energies ranging from sub-MeV to 20 MeV. A typical set of data obtained simultaneously by the detectors is shown, measuring the neutron spectrum emitted from a petawatt laser irradiated thin foil.

Abstract
BACKGROUND We report the development of a cutaneous melanoma risk algorithm based upon seven factors; hair color, skin type, family history, freckling, nevus count, number of large nevi, and history of sunburn, intended to form the basis of a self-assessment Web tool for the general public. METHODS Predicted odds of melanoma were estimated by analyzing a pooled dataset from 16 case-control studies using logistic random coefficients models. Risk categories were defined based on the distribution of the predicted odds in the controls from these studies. Imputation was used to estimate missing data in the pooled datasets. The 30th, 60th, and 90th centiles were used to distribute individuals into four risk groups for their age, sex, and geographic location. Cross-validation was used to test the robustness of the thresholds for each group by leaving out each study one by one. Performance of the model was assessed in an independent UK case-control study dataset. RESULTS Cross-validation confirmed the robustness of the threshold estimates. Cases and controls were well discriminated in the independent dataset [area under the curve, 0.75; 95% confidence interval (CI), 0.73-0.78]. Twenty-nine percent of cases were in the highest risk group compared with 7% of controls, and 43% of controls were in the lowest risk group compared with 13% of cases. CONCLUSION We have identified a composite score representing an estimate of relative risk and successfully validated this score in an independent dataset. IMPACT This score may be a useful tool to inform members of the public about their melanoma risk.

Abstract
Neuromyelitis optica (NMO) is an inflammatory autoimmune disease of the central nervous system that preferentially targets the optic nerves and spinal cord. The clinical presentation may suggest multiple sclerosis (MS), but a highly specific serum autoantibody against the astrocytic water channel aquaporin-4 present in up to 80% of NMO patients enables distinction from MS. Optic neuritis may occur in either condition resulting in neuro-anatomical retinal changes. Optical coherence tomography (OCT) has become a useful tool for analyzing retinal damage both in MS and NMO. Numerous studies showed that optic neuritis in NMO typically results in more severe retinal nerve fiber layer (RNFL) and ganglion cell layer thinning and more frequent development of microcystic macular edema than in MS. Furthermore, while patients’ RNFL thinning also occurs in the absence of optic neuritis in MS, subclinical damage seems to be rare in NMO. Thus, OCT might be useful in differentiating NMO from MS and serve as an outcome parameter in clinical studies.

Abstract
OBJECTIVE To investigate, at a population level, whether a family history of abdominal aortic aneurysm (AAA) is independently related to increased aortic diameter and prevalence of AAA in men, and to elucidate whether the mean aortic diameter and the prevalence of AAA are different between participants with male and female relatives with AAA. DESIGN Observational population-based cross-sectional study. MATERIALS 18,614 male participants screened for AAA in the VIVA-trial 2008-2011 with information on both family history of AAA and maximal aortic diameter. METHODS Standardized ultrasound scan measurement of maximum antero-posterior aortic diameter. Family history obtained by questionnaire. Multivariate regression analysis was used to test for confounders: age, sex, smoking, comorbidity and medication. RESULTS From the screened cohort, 569 participants had at least one first degree relative diagnosed with AAA, and 38 had AAA. Participants with a family history of AAA (+FH) had a significantly larger mean maximum aortic diameter (20.50 mm) compared with participants without family history of AAA (-FH) (19.07 mm, p < .0001), and +FH with female relatives with AAA had significantly larger mean maximum aortic diameter (21.8 mm) than +FH with male relatives (19.9 mm, p = .007). Furthermore the prevalence of AAA was significantly higher among +FH (6.7%) compared with -FH (3.0%) with an odds ratio (OR) of 2.2 (95% CI: 1.6 to 3.2, p < .001) and +FH with female relatives with AAA had a more than two and a half times increased prevalence of AAA compared with +FH with male relatives with AAA with an OR of 2.65. CONCLUSIONS First-degree male relatives of AAA patients have wider aortas and a twofold higher prevalence of AAA compared with the age adjusted background population. The prevalence of AAA was markedly higher in participants related to female, rather than male, patients with AAA.

Abstract
A novel method for characterising the full spectrum of deuteron ions emitted by laser driven multi-species ion sources is discussed. The procedure is based on using differential filtering over the detector of a Thompson parabola ion spectrometer, which enables discrimination of deuterium ions from heavier ion species with the same charge-to-mass ratio (such as C(6+), O(8+), etc.). Commonly used Fuji Image plates were used as detectors in the spectrometer, whose absolute response to deuterium ions over a wide range of energies was calibrated by using slotted CR-39 nuclear track detectors. A typical deuterium ion spectrum diagnosed in a recent experimental campaign is presented, which was produced from a thin deuterated plastic foil target irradiated by a high power laser.

Abstract
The treatment of complex wounds is difficult and not always effective. Various treatment options are used with varying degrees of success. Negative pressure wound therapy (NPWT) is a cost-efficient and effective way to help treat these wounds. The use of a vacuum device applies the negative pressure to the site of the wound and promotes waste removal and increases circulation and tissue formation. While various NPWT systems are currently on the market, we utilised the ConvaTec Engenex® system with Bio-DomeTM technology; however, our case study is not intended to advocate the specific use of this system, but instead focuses on the use of NPWT as a viable option for wound healing. Each of the following case study patients presented with difficult-to-heal wounds that failed traditional therapeutic approaches. Through the use of NPWT, our patients saw major wound size reductions. Each patient exhibited at least a 94% reduction in wound area, wound volume or both.

Abstract
Patients with neurofibromatosis type 1 (nf1) are at increased risk for both benign and malignant tumours, and distinguishing the malignant potential of an individual tumour is a common clinical problem in these patients. Here, we review two cases of uncommon malignancies (Hodgkin lymphoma and mediastinal germ-cell tumour) in patients with nf1. Although (18)F-fluorodeoxyglucose positron-emission tomography (fdg-pet) has been used to differentiate benign neurofibromas from malignant peripheral nerve sheath tumours, fdg-pet characteristics for more rare tumours have been poorly described in children with nf1. Here, we report the role of pet imaging in clinical decision-making in each case. In nf1, fdg-pet might be useful in the clinical management of unusual tumour presentations and might help to provide information about the malignant potential of uncommon tumours.

Abstract
Abstract
Introduction of targeted therapies into oncology requires co development of a drug and its companion diagnostic to achieve clinical efficacy and minimise side effects. Given the aggressive nature of estrogen receptor alpha negative (ERa-ve) breast cancer (BrCa), novel therapeutics are needed. Gamma-secretase enzyme is a relevant target in cancer, and within it, Nicastrin (NCSTN) is amenable to therapeutic intervention using monoclonal antibodies (mAb). NCSTN gene is amplified in a some breast tumours, which correlates with high NCSTN mRNA and adversely impacts overall survival (TCGA, Nature 2012). Immunohistochemistry revealed NCSTN protein overexpression in 47.5% of BrCa (n = 1000), conferring worse prognosis in the ERα-ve cohort. NCSTN genetic depletion in triple negative BrCa cells attenuated tumor growth in vitro and in vivo, invasive capacity, mesenchymal features and cancer stem-cell propagation (Filipovic et al; Lombardo et al). We have developed and characterized anti-NCSTN mAbs in terms of their therapeutic properties, functional effects in vitro and in vivo, and binding epitopes. Here, we have used a novel, bright-field chromogenic in situ hybridization technique (RNAscope), to quantify single-cell NCSTN mRNA levels in ERα-ve BrCa patients (n = 311), and propose this test as a companion diagnostic for targeted anti-NCSTN therapy. Methods:Paraffin BrCa tissue microarrays sections (Nottingham Tenovus ERα-ve cohort; n = 311) were analyzed by RNAScope using a NCSTN-specific probe (GenBank accession number NM_015331.2, and probe region: nt 158-1306). Visualized as brown punctate dots, RNA staining in individual tumor cells was scored semi-quantitatively on a 1-4 scale: 1 = 0-5 dots/cell, 2 = 6-10 dots/cell, 3 = 11-15 dots/cell, 4 = >16 dots/cell. H-score (100-400) capturing the percentage of tumor cells at each staining level was calculated and correlated with clinical and tumour characteristics. Results: NCSTN high H-score >120 correlated with high proliferative index (Ki67) (p = 0.002), high nuclear pleomorphism (p = 0.03) and mitotic score (p = 0.02) and membranous expression of the NCSTN protein (p = 0.05). It further correlated with cytoplsmic BRCA1 positivity (p = 0.025), which is associated with BrCa cell invasion. Importantly, in Kaplan-Meier analyses NCSTN Score>120 conferred a higher probability of metastatic relapse at 10-year follow up (p = 0.019), and retained significance in the Cox regression multivariate analysis, along with tumor grade, stage and size (p = 0.04). Conclusion: RNAScope successfully detected NCSTN mRNA in paraffin embedded BrCa tissues. High NCSTN RNAScope levels may be a novel independent prognostic factor in this patient cohort and one that correlates with established markers of aggressive disease. We will also present data on anti-NCSTN mAb efficacy in cell systems based on NCSTN RNAScope score. We propose that detection of high NCSTN levels by RNAScope in primary BrCa removed at surgery or in subsequent biopsies of disease relapse can be further developed to serve as a clinical companion diagnostic test to assess patient eligibility for treatment using anti-NCSTN therapy.

Abstract
INTRODUCTION Prostate cancer is the commonest cancer in men and a major health issue worldwide. Screening for early disease has been available for many years, but there is still no national screening programme established in the United Kingdom. OBJECTIVE To assess the latest evidence regarding prostate cancer screening and whether it meets the necessary requirements to be established as a national programme for all men. METHODS Electronic databases and library catalogues were searched electronically and manual retrieval was performed. Only primary research results were used for the analysis. RESULTS In recent years, several important randomised controlled trials have produced varied outcomes. In Europe the largest study thus far concluded that screening reduced prostate cancer mortality by 20%. On the contrary, a large American trial found no reduction in mortality after 7-10 years follow-up. Most studies comment on the adverse effects of screening - principally those of overdiagnosis and subsequent overtreatment. DISCUSSION Further information about the natural history of prostate cancer and accuracy of screening is needed before a screening programme can be truly justified. In the interim, doctors and patients should discuss the risks, benefits and sequelae of taking part in voluntary screening for prostate cancer.
