Contact lens migration into the upper lid is a rare complication of wearing a hard contact lens. We present a case in which the only complaint was the cosmetically unacceptable appearance of a lump in the upper lid. The 76-month duration of the lesion is, we believe, the longest so far described. The histology and possible natural history of the cyst are also discussed.

The Scratchpad Virtual Research Environment (http://scratchpads.eu/) is a flexible system for people to create their own research networks supporting natural history science. Here we describe Version 2 of the system characterised by the move to Drupal 7 as the Scratchpad core development framework and timed to coincide with the fifth year of the project's operation in late January 2012. The dev...

Until the mid-19th century, there had not been a single resident physician in the Holy Land. However, by the first World War in 1914, 19 hospitals had been established in Jerusalem. The reasons for this unusual phenomenon were religious, political, and sectarian. This does not apply to The Marienstift Kinderhospital, which was unique in 19th century Jerusalem. The hospital was founded and opera...

Current research recognizes that both the spatial and temporal structure of the landscape influence species persistence. Patch models that incorporate the spatial structure of the landscape have been used to investigate static habitat destruction by comparing persistence results within nested landscapes. Other researchers have incorporated temporal structure into their models by making habitat ...

After a brief epidemiologic survey of endometrial cancer, the subject of detection and diagnosis of early lesions is addressed. Emphasis is placed on major gaps that exist in the knowledge of natural history of the disease. Cytologic and histologic detection and diagnostic techniques are reviewed and their advantages and disadvantages discussed.

This article presents a rereading of Buffon's Natural History in the light of the concepts of temporal reversibility and irreversibility. The goal is to determine to what extent Buffon introduces a transformationist concept of natural forms in this work. To that effect, the main points of classical natural history and the doctrine of preformed germs are analyzed. Subsequently, Buffon's use of t...
