Abstract
ZusammenfassungWir berichten über einen 46-jährigen Patienten mit einer seit 20 Jahren bestehenden Diagnose einer chronischen Immunthrombozytopenie. Die Vorstellung des Patienten in unserer Gerinnungsambulanz erfolgte zur Abklärung der Thrombozytopenie und zur Therapieempfehlung vor geplantem Eingriff zur operativen Spermatozoengewinnung bei einer nicht obstruktiven Azoospermie und Kinderwunsch. Kortikosteroide zeigten in der Vergangenheit keinen klinischen Effekt. Klinisch relevante Blutungen waren bisher nicht aufgetreten. Im Alter von 36 Jahren wurde eine Kataraktoperation durchgeführt, ferner bestand ein beginnender Hörverlust im hohen Frequenzbereich. Unsere Untersuchungen ergaben eine Plättchenzahl von 31 × 109/l, ein erhöhtes mittleres Thrombozytenvolumen (MPV 16,8 fl) und keinen Nachweis freier oder gebundener thrombozytärer Autoantikörper. Ein Bernard-Soulier-Syndrom konnte ausgeschlossen werden. Im Blutausstrich zeigten sich Einschlusskörperchen in den neutrophilen Granulozyten. Der Verdacht auf eine MYH9-assoziierte Thrombozytopenie konnte durch eine genetische Untersuchung des MYH9-Gens bestätigt werden (c.5717C>T; p.Thr1906Met [heterozygot]) und eine heterozygote Duplikation des Bereichs des Intron-Exon-Übergangs von Exon 37. Die testikuläre Spermienextraktion konnte erfolgreich mit präoperativer Gabe von Desmopressin i. v. durchgeführt werden. Dieser Fall zeigt, dass Patienten mit einer MYH9-assoziierten Thrombozytopenie als Patienten mit Immunthrombozytopenie fehldiagnostiziert werden können und es dadurch zu falschen Therapieentscheidungen kommen kann. Dabei kann die einfache Beurteilung des mittleren Thrombozytenvolumens und des Blutausstrichs bei der Diagnosefindung sehr hilfreich sein.

Abstract
Platelet autoantibody-induced platelet clearance represents a major pathomechanism in immune thrombocytopenia (ITP). There is growing evidence for clinical differences between anti-glycoprotein IIb/IIIa and anti-glycoprotein Ib/IX mediated ITP. Glycoprotein V is a well characterized target antigen in Varicella-associated and drug-induced thrombocytopenia. We conducted a systematic study assessing the prevalence and functional capacity of autoantibodies against glycoprotein V. A total of 1140 patients were included. In one-third of patients, platelet-bound autoantibodies against glycoproteins Ib/IX, IIb/IIIa, or V were detected in a monoclonal antibody immobilization of platelet antigen assay; platelet-bound autoantiglycoprotein V was present in the majority of samples (222 out of 343, 64.7%). Investigation of patient sera revealed the presence of free autoantibodies against glycoprotein V in 13.5% of these patients by an indirect monoclonal antibody immobilization of platelet antigen assay, but in 39.6% by surface plasmon resonance technology. These antibodies showed significantly lower avidity (association/dissociation ratio 0.32±0.13 vs. 0.73±0.14; P<0.001). High- and low-avidity antibodies induced comparable amounts of platelet uptake in a phagocytosis assay using CD14+ positively-selected human macrophages [mean phagocytic index, 6.81 (range, 4.75-9.86) vs. 6.01 (range, 5.00-6.98); P=0.954]. In a NOD/SCID mouse model, IgG prepared from both types of anti-glycoprotein V autoantibodies eliminated human platelets with no detectable difference between the groups from the murine circulation [mean platelet survival at 300 minutes, 40% (range, 27-55) vs. 35% (16-46); P=0.025]. Our data establish glycoprotein V as a relevant immune target in immune thrombocytopenia. We would suggest that further studies including glycoprotein V will be required before ITP treatment can be tailored according to platelet autoantibody specificity.

Abstract
Laparoscopy is widely utilised to diagnose and treat acute and chronic, gynaecological and general surgical conditions. It has only been in recent years that laparoscopy has become an acceptable surgical alternative to open surgery in pregnancy. To date there is little clinical guidance pertaining to laparoscopic surgery in pregnancy. This is why the BSGE commissioned this guideline. MEDLINE, EMBASE, CINAHL and the Cochrane library were searched up to February 2017 and evidence was collated and graded following the NICE-approved process. The conditions included in this guideline are laparoscopic management of acute appendicitis, acute gall bladder disease and symptomatic benign adnexal tumours in pregnancy. The intended audience for this guideline is obstetricians and gynaecologists in secondary and tertiary care, general surgeons and anaesthetists. However, only laparoscopists who have adequate laparoscopic skills and who perform complex laparoscopic surgery regularly should undertake laparoscopy in pregnant women, since much of the evidence stems from specialised centres.

Abstract
Persuasive messages can change people's thoughts, feelings, and actions, but these effects depend on how people think about and appraise the meaning of these messages. Drawing from research on the cognitive control of emotion, we used neuroimaging to investigate neural mechanisms underlying cognitive regulation of the affective and persuasive impact of advertisements communicating the risks of binge drinking, a significant public health problem. Using cognitive control to up-regulate (vs. down-regulate) responses to the ads increased: negative affect related to consequences of excessive drinking, perceived ad effectiveness, and ratings of ad self-relevance made after a one-hour delay. Neurally, these effects of cognitive control were mediated by goal-congruent modulation of ventromedial prefrontal cortex and distributed brain patterns associated with negative emotion and subjective valuation. These findings suggest that people can leverage cognitive control resources to deliberately shape responses to persuasive appeals, and identify mechanisms of emotional reactivity and integrative valuation that underlie this ability. Specifically, brain valuation pattern expression mediated the effect of cognitive goals on perceived message self-relevance, suggesting a role for the brain's valuation system in shaping responses to persuasive appeals in a manner that persists over time.

Abstract
Despite three decades of successful, predominantly phenotype-driven discovery of the genetic causes of monogenic disorders, up to half of children with severe developmental disorders of probable genetic origin remain without a genetic diagnosis. Particularly challenging are those disorders rare enough to have eluded recognition as a discrete clinical entity, those with highly variable clinical manifestations, and those that are difficult to distinguish from other, very similar, disorders. Here we demonstrate the power of using an unbiased genotype-driven approach to identify subsets of patients with similar disorders. By studying 1,133 children with severe, undiagnosed developmental disorders, and their parents, using a combination of exome sequencing and array-based detection of chromosomal rearrangements, we discovered 12 novel genes associated with developmental disorders. These newly implicated genes increase by 10% (from 28% to 31%) the proportion of children that could be diagnosed. Clustering of missense mutations in six of these newly implicated genes suggests that normal development is being perturbed by an activating or dominant-negative mechanism. Our findings demonstrate the value of adopting a comprehensive strategy, both genome-wide and nationwide, to elucidate the underlying causes of rare genetic disorders.

Abstract
Background Scalds are one of the most common forms of thermal injury in young children worldwide. Childhood scald injuries, which mostly occur in the home, result in substantial health service use and considerable morbidity and mortality. There is little research on effective interventions to prevent scald injuries in young children. Objectives To determine the relationship between a range of modifiable risk factors for medically attended scalds in children under the age of 5 years. Design A multicentre case-control study in UK hospitals and minor injury units with parallel home observation to validate parental reported exposures. Cases will be 0–4 years old with a medically attended scald injury which occurred in their home or garden, matched on gender and age with community controls. An additional control group will comprise unmatched hospital controls drawn from children aged 0–4 years attending the same hospitals and minor injury units for other types of injury. Conditional logistic regression will be used for the analysis of cases and matched controls, and unconditional logistic regression for the analysis of cases and unmatched controls to estimate ORs and 95% CI, adjusted and unadjusted for confounding variables. Main exposure measures Use of safety equipment and safety practices for scald prevention and scald hazards. Discussion This large case-control study will investigate modifiable risk factors for scalds injuries, adjust for potential confounders and validate measures of exposure. Its findings will enhance the evidence base for prevention of scalds injuries in young children.

Abstract
OBJECTIVES Prompt HIV diagnosis and treatment are associated with increased longevity and reduced transmission. The aim of the study was to examine late diagnoses and to assess the quality of care following diagnosis. METHODS National surveillance and cohort data were used to examine late HIV diagnoses and to assess the quality of care received in the 12 months following HIV diagnosis. RESULTS In 2011, 79% (4910/6219) of persons (15 years and over) diagnosed with HIV infection had CD4 counts reported within 3 months; of these, 49% were diagnosed late (CD4 count < 350 cells/μL). Adults aged 50 years and over were more likely to be diagnosed late (67%) compared with those aged 15-24 years (31%). Sixty-four per cent of heterosexual men were diagnosed late compared with 46% of women and 36% of men who have sex with men (MSM) (P < 0.01). The percentage of late diagnoses was highest among black African adults (66%) compared with other ethnicities; 96% of black African adults diagnosed late were born abroad. Overall, 88% and 97% of patients were linked to care within 1 and 3 months of diagnosis, respectively, with little variation by demographics and exposure category. The crude 1-year mortality rate was 31.6 per 1000 persons diagnosed in 2010. It was highest among adults diagnosed late (40.3/1000 versus 5.2/1000 for prompt diagnoses) and particularly among those aged 50 years and over. Excluding deaths, 85% of the 5833 diagnosed in 2010 were retained in care in 2011; 92% of the 2264 adults diagnosed late in 2010 received antiretroviral therapy by the end of 2011. CONCLUSIONS The National Health Service provides high-quality care to persons newly diagnosed with HIV infection in the UK, with no evidence of health inequalities. Despite excellent care, half of adults are diagnosed late according to the threshold at which national guidelines recommend treatment should begin. Such patients have an 8-fold increased risk of 1-year mortality compared with those diagnosed promptly. Reducing late diagnosis of HIV infection remains a public health priority in the UK.

Classical novae are expected to contribute to the 1809-keV Galactic γ-ray emission by producing its precursor 26Al, but the yield depends on the thermonuclear rate of the unmeasured 25Al(p,γ)26Si reaction. Using the β decay of 26P to populate the key J(π)=3(+) resonance in this reaction, we report the first evidence for the observation of its exit channel via a 1741.6±0.6(stat)±0.3(syst) keV primary γ ray, where the uncertainties are statistical and systematic, respectively. By combining the measured γ-ray energy and intensity with other experimental data on 26Si, we find the center-of-mass energy and strength of the resonance to be E(r)=414.9±0.6(stat)±0.3(syst)±0.6(lit.) keV and ωγ=23±6(stat)(-10)(+11)(lit.) meV, respectively, where the last uncertainties are from adopted literature data. We use hydrodynamic nova simulations to model 26Al production showing that these measurements effectively eliminate the dominant experimental nuclear-physics uncertainty and we estimate that novae may contribute up to 30% of the Galactic 26Al.
