PURPOSE Functions of antimicrobial peptidoglycan recognition proteins (Pglyrp1-4) at the ocular surface are poorly understood. Earlier, we reported an antibacterial role for Pglyrp-1 in Pseudomonas aeruginosa keratitis. Here we investigated functions of three other related genes Pglyrp-2, -3 and -4 in a mouse model of P. aeruginosa keratitis. METHODS Wild type (WT) and each of the Pglyrp-null...

OBJECTIVE The sensorimotor organization (SMO) of the motor hand area is abnormal in focal hand dystonia and likely contributes to symptom manifestation. In healthy subjects SMO is changed by training with proprioceptive stimulation. Here we test whether similar interventions reverse the abnormal SMO in musician's dystonia and writer's cramp. If so, they could be developed for therapeutic applic...

Neurophysiological studies in animals show that basal ganglia are involved not only in motor and nonmotor timing functions but also in integrating tactile and visual signals delivered in the peripersonal space. We tested temporal discrimination of cross-modal and unimodal stimuli in 13 controls and 14 patients with writer's cramp, a disorder supposedly linked to dysfunction of basal ganglia. Su...

In (perhaps) one of the largest series, treatment of 30 cases of writer's cramp by behaviour therapy alone, has been studied over a period of 5 years. The therapy techniques used were (i) relaxation therapy and retraining (ii) relaxation therapy, retraining and systematic desenetization. The outcome of both the techniques are very encouraging and show definite improvement in all cases. Various ...

Simple tapping and complex movements (Luria finger apposition task) were performed unimanually and bimanually by two groups of professional guitarists while EEG was recorded from electrodes over the sensorimotor cortex. One group had a task-specific movement disorder (focal dystonia or musicians’ cramp), while the other group did not (controls). There were no significant group interactions in t...
