Purpose. To identify changing trends in indications for penetrating keratoplasty and associated surgical procedures. Methods. Review of charts from all patients who underwent penetrating keratoplasty at Wills Eye Hospital from January 1, 1989 through December 31, 1995. Results. A total of 2,442 corneal transplants were performed in 2,186 patients. The leading indication for penetrating keratoplasty was pseudophakic corneal edema, accounting for 634 cases (26.0%); 54.7% of them were associated with anterior chamber intraocular lenses, 36.4% with posterior chamber intraocular lenses, and 3.1% with iris-fixated intraocular lenses. Regraft (17.8%), Fuchs' dystrophy (15.7%), and keratoconus (13.2%) followed pseudophakic corneal edema in frequency. Cataract extraction, with or without intraocular lens implantation, was combined with penetrating keratoplasty in 439 cases of 1,264 phakic eyes (34.7%). Intraocular lens exchange was performed in 285 of the 634 cases of pseudophakic cornea edema (44.9%). Conclusion. Pseudophakic corneal edema was the leading indication for penetrating keratoplasty, with an increasing number of cases associated with posterior chamber intraocular lenses during the study period (p = 0.001). The number of regrafts steadily increased between 1989 and 1995 (p = 0.001), being the second most common indication for corneal transplantation since 1992.

Building upon recent studies by geographers and social scientists on the everyday practices of (scientific) observation, this paper focuses on the role of two distinct, yet similar organisations that held observation as an essential and 'automatic' embodied skill. Utilising the examples of Home Guard camouflage and the Boy Scout Movement, the paper critically examines how these organisations sought to articulate the individual as both observer and observed, thereby exposing a much more complex entanglement of different visual positions and practices hitherto neglected in studies of observation. Moreover, the paper emphasises the importance of the act of 'not-being-seen' as a complementary and fundamental aspect of (non-)observational practice, accentuated and promoted by civic institutions in terms of duty and responsibility. Finally, the paper considers the evolutionary aspects of observation through the lifecourse, revealing a complex, relational geography of expertise, experience and skill that crossed age-distinctions. © 2012 Elsevier Ltd.

The influence of collective memory on political identity in Ireland has been well documented. It has particular force in Northern Ireland where there is fundamental disagreement about how and why the conflict erupted and how it should be resolved. This article outlines some of the issues encountered by an ‘insider’ when attempting to record and analyse the conflicting memories of a range of Protestants and Catholics who grew up in Mid-Ulster in the decades preceding the Troubles. In particular, it considers the challenges and opportunities presented by a two-pronged approach to oral history: using testimony as evidence about historical experience in the past and as evidence about historical memory – both collective and individual – in the present.

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.

Featuring a brand new examination of Islamic fundamentalism in the wake of the Arab Spring, this fully revised and updated second edition of Islamic Fundamentalism since 1945 analyzes the roots and emergence of Islamic movements in the modern world and the main thinkers that inspired them.

Providing a much-needed historical overview of a fast-changing socio-political landscape, the main facets of Islamic fundamentalism are put in a global context, with a thematic debate of issues such as:

- the effects of colonialism on Islam

- secularism and the Islamic reaction

- Islam and violence in the 9/11 era

- globalization and transnational Islamist movements

- Islam in the wake of the Arab Awakening

Islamic Fundamentalism since 1945 provides an authoritative account of the causes and diversity of Islamic fundamentalism, a modern phenomenon which has grabbed the headlines as a grave threat to the West and a potentially revolutionary trend in the Middle East. It is a valuable resource for students and those interested in the history, effects and consequences of these Islamic movements

This third edition of Conflicts in the Middle East since 1945 analyzes the nature of conflict in the Middle East, with its racial, ethnic, political, cultural, religious and economic factors. Throughout the book Peter Hinchcliffe and Beverley Milton-Edwards put the main conflicts into their wider context, with thematic debates on issues such as the emergence of radical Islam, the resolution of conflicts, diplomacy and peace-making, and the role of the superpowers.

The book is brought fully up to date with events in the Middle East, covering, for instance, developments in Iraq in 2006 where a democratically elected government is in place but the insurgency show no sign of coming under control. The analysis of the Palestinian/Israeli conflict is also brought up to the present day, to include the election of the Hamas government and the 2006 conflict between Israel and Lebanon’s Hizballah.

Including a newly updated bibliography and maps of the area, this is the perfect introduction for all students wishing to understand the complex situation in the Middle East, in its historical context.
