Olmesartan-induced enteropathy associated with cutaneous lesions.

Olmesartan is an angiotensin II receptor antagonist which may cause severe sprue-like enteropathy with duodenal villous atrophy. Skin lesions may be associated as reported for the first time in our case. Clinicians should be informed of this side effect and its reversibility after suspension of the drug.

Improved retrievals of the optical properties of cirrus clouds by a combination of lidar methods.

We focus on improvement of the retrieval of optical properties of cirrus clouds by combining two lidar methods. We retrieve the cloud's optical depth by using independently the molecular backscattering profile below and above the cloud [molecular integration (MI) method] and the backscattering profile inside the cloud with an a priori effective lidar ratio [particle integration (PI) method]. When the MI method is reliable, the combined MI-PI method allows us to retrieve the optimal effective lidar ratio. We compare these results with Raman lidar retrievals. We then use the derived optimal effective lidar ratio for retrieval with the PI method for situations in which the MI method cannot be applied.
