The Agate Lamp

Noncompliance in antiplatelet trials: the AGATE trial perspective.

Noncompliance in Antiplatelet Trials: The AGATE Trial Perspective To the Editor: Recent studies have highlighted the importance of patient compliance in clinical trials of antiplatelet therapy. The AGATE trial1 was designed as a head-to-head comparison of the antiplatelet properties of Aggrenox (a combination of aspirin and dipyridamole) versus aspirin alone in patients with a recent history of...

AGATE: Unifying Languages and Operating Systems

Study of agate using the OSL technique and application in

The possibility of using Brazilian stones in gamma high-dose dosimetry was investigated at IPEN using the optically stimulated luminescence (OSL) technique. Agate samples were studied in relation to their OSL dosimetric properties, in this work. The samples were irradiated at a Gamma-Cell system (Co). The calibration curves show a sublinear behavior between 50 Gy and 300 kGy, and the lower dete...

The fundus slit lamp

Fundus biomicroscopy with the slit lamp as it is practiced widely nowadays was not established until the 1980-es with the introduction of the Volk lenses +90 and +60D. Thereafter little progress has been made in retinal imaging with the slit lamp. It is the aim of this paper to fully exploit the potential of a video slit lamp for fundus documentation by using easily accessible additions. Suitab...

Wood lamp examination.

Pigment disorders1,3 Hypopigmentation or depigmentation. Lesions demonstrate increased sharpness of borders under Wood lamp examination and fluoresce bright blue-white owing to the increased amount of dermal collagen illuminated. This results from decreased or absent intervening melanin. Vitiligo: patches, varying in location and extent. Tuberous sclerosis: patches; characteristic shapes are la...
