The classification of inherited epidermolysis bullosa (EB): Report of the Third International Consensus Meeting on Diagnosis and Classification of EB.

Abstract: BACKGROUND: Since publication in 2000 of the Second International Consensus Report on Diagnosis and Classification of Epidermolysis Bullosa, many advances have been made to our understanding of this group of diseases, both clinically and molecularly. At the same time, new epidermolysis bullosa (EB) subtypes have been described and similarities with some other diseases have been identified. OBJECTIVE: We sought to arrive at a new consensus of the classification of EB subtypes. RESULTS: We now present a revised classification system that takes into account the new advances, as well as encompassing other inherited diseases that should also be included within the EB spectrum, based on the presence of blistering and mechanical fragility. Current recommendations are made on the use of specific diagnostic tests, with updates on the findings known to occur within each of the major EB subtypes. Electronic links are also provided to informational and laboratory resources of particular benefit to clinicians and their patients. LIMITATIONS: As more becomes known about this disease, future modifications may be needed. The classification system has been designed with sufficient flexibility for these modifications. CONCLUSION: This revised classification system should assist clinicians in accurately diagnosing and subclassifying patients with EB.

Anal human papillomavirus infection and associated neoplastic lesions in men who have sex with men: a systematic review and meta-analysis

Abstract: Summary Background Men who have sex with men (MSM) are at greatly increased risk of human papillomavirus (HPV)-associated anal cancer. Screening for the presumed cancer precursor, high-grade anal intraepithelial neoplasia (AIN), followed by treatment in a manner analogous to cervical screening, has been proposed. We aimed to assess available data for anal HPV disease that can inform pre-cancer screening programmes. Methods We searched PubMed, OVID Medline, and Embase for all studies published before Nov 1, 2011, that reported prevalence and incidence of anal HPV detection, AIN, and anal cancer in MSM. We calculated summary estimates using random-effects meta-analysis. Findings 53 studies met the inclusion criteria, including 31 estimates of HPV prevalence, 19 estimates of cytological abnormalities, eight estimates of histological abnormalities, and nine estimates of anal cancer incidence. Data for incident HPV and high-grade AIN were scarce. In HIV-positive men, the pooled prevalence of anal HPV-16 was 35·4% (95% CI 32·9–37·9). In the only published estimate, incidence of anal HPV-16 was 13·0% (9·6–17·6), and clearance occurred in 14·6% (10·2–21·2) of men per year. The pooled prevalence of histological high-grade AIN was 29·1% (22·8–35·4) with incidences of 8·5% (6·9–10·4) and 15·4% (11·8–19·8) per year in two estimates. The pooled anal cancer incidence was 45·9 per 100 000 men (31·2–60·3). In HIV-negative men, the pooled prevalence of anal HPV-16 was 12·5% (9·8–15·4). Incidence of HPV-16 was 11·8% (9·2–14·9) and 5·8% (1·9–13·5) of men per year in two estimates. The pooled prevalence of histological high-grade AIN was 21·5% (13·7–29·3), with incidence of 3·3% (2·2–4·7) and 6·0% (4·2–8·1) per year in two estimates. Anal cancer incidence was 5·1 per 100 000 men (0–11·5; based on two estimates). There were no published estimates of high-grade AIN regression. Interpretation Anal HPV and anal cancer precursors were very common in MSM. However, on the basis of restricted data, rates of progression to cancer seem to be substantially lower than they are for cervical pre-cancerous lesions. Large, good-quality prospective studies are needed to inform the development of anal cancer screening guidelines for MSM. Funding Australian Government Department of Health and Ageing.

Global increasing trends in annual maximum daily precipitation

Abstract: This study investigates the presence of trends in annual maximum daily precipitation time series obtained from a global dataset of 8326 high-quality land-based observing stations with more than 30 years of record over the period from 1900 to 2009. Two complementary statistical techniques were adopted to evaluate the possible nonstationary behavior of these precipitation data. The first was a Mann‐Kendall nonparametric trend test, and it was used to evaluate the existence of monotonic trends. The second was a nonstationary generalized extreme value analysis, and it was used to determine the strength of association between the precipitation extremes and globally averaged near-surface temperature. The outcomes are that statistically significant increasing trends can be detected at the global scale, with close to two-thirds of stations showing increases. Furthermore, there is a statistically significant association with globally averaged near-surface temperature,withthemedianintensityofextremeprecipitationchanginginproportionwithchangesinglobal mean temperature at a rate of between 5.9% and 7.7%K 21 , depending on the method of analysis. This ratio was robust irrespective of record length or time period considered and was not strongly biased by the uneven global coverage of precipitation data. Finally, there is a distinct meridional variation, with the greatest sensitivity occurring in the tropics and higher latitudes and the minima around 138S and 118N. The greatest uncertainty was near the equator because of the limited number of sufficiently long precipitation records, and there remains an urgent need to improve data collection in this region to better constrain future changes in tropical precipitation.
