The Origin of the Knee Anterolateral Ligament Discovery: A Translation of Segond's Original Work With Commentary.

Paul Segond was a French surgeon who was in practice at the end of the 19th century. A prodigious anatomist, scientist, and surgeon in his day, he is best known for his treatise on the origin of traumatic hemarthrosis of the knee following injury. In this detailed description of the anatomy of the anterolateral aspect of the knee, he describes "a pearly, resistant, fibrous band that is placed under extreme tension when the knee is forcefully rotated internally," which has more recently been described as the anterolateral ligament or a capsular thickening contributing to the anterolateral complex of the knee.

Prevalence and trends of infection with Mycobacterium tuberculosis in Djibouti, testing an alternative method.

Setting: Djibouti, 1994 and 2001.

Objective: To estimate the prevalence of tuberculosis (TB) and average annual risk of TB infection (ARTI) and trends, and to test a new method for calculations.

Methods: Tuberculin surveys among schoolchildren and sputum smear-positive TB patients.

24 hour polysomnographic evaluation in a patient with sleeping sickness.

A 24 h polysomnographic recording was performed in a patient with sleeping sickness presenting an atypical neurological syndrome. Trypanosoma gambiense was found in a lymph gland puncture and the CSF, and a serologic immunofluorescence test was positive. The scoring technique of the polygraphic traces had to be adapted because of the presence of a permanent EEG delta wave activity during the NREM sleep stages, and the method used by Schwartz and Escande (1970) was applied.
