RESUMEN
Focal dystonia (FD) can develop after thalamic lesions. Abnormal somatic sensations were argued to be responsible for FD. Our patient experienced FD-like movement disorders, agraphesthesia, and a reduced sense of shear force on the skin and pressure to deep tissues of the right upper limb following a small infarction in the left posterolateral thalamus. FD-like symptoms improved while the skin was being pulled or the deep tissue was being pushed in a manner proportional to the strength of muscle contractions. Therefore, the lack of these sensations was suggested to be related to FD-like symptoms.

Three new rearranged vibsane-type diterpenes, neovibsanin F (1), 14-epi-neovibsanin F (2), and 14-epi-18-oxoneovibsanin F (3), have been isolated from the leaves of Viburnum suspensum, and their structures were elucidated on the basis of spectroscopic data and comparison with those of previously reported vibsane-type diterpenes.
