Behcet's disease is a chronic relapsing-remitting, multi-system inflammatory disorder of unknown etiology, characterized by recurrent oral and genital ulcers, uveitis, and skin lesions. The most common central nervous system findings are demyelization and perivascular cell infiltration; meningoencephalitis, cerebral atrophy, and vascular thrombosis may also occur. Neuropsychiatric symptoms may include: paroxysmal dystonia, parkinsonism, delirium, hallucinations, and behavioral disturbances. We report an unusual case of explosive onset of motor and vocal tics with obsessive-compulsive symptoms in a 22-year-old male with Behcet's disease. The putative roles of infection and autoimmune mechanisms in the pathogenesis of tics and obsessive-compulsive symptoms are explored.

We describe a 34 year old woman presenting with a 25 year history of segmental dystonia with apraxia of eyelid opening, orofacial and focal upper limb dystonia following an episode of meningoencephalitis. Post-encephalitic apraxia of eyelid opening has not been previously reported in the absence of parkinsonian features.

Streptococcus pneumoniae is a common cause of bacterial meningitis, frequently resulting in severe neurological impairment. A seven-month-old child presenting with Streptococcus pneumoniae meningoencephalitis developed right basal ganglia and hypothalamic infarctions. Daily episodes of agitation, hypertension, tachycardia, diaphoresis, hyperthermia, and decerebrate posturing were observed. The diagnosis of paroxysmal autonomic instability with dystonia was established. The patient responded to clonidine, baclofen, and benzodiazepines. Although this entity has been reported in association with traumatic brain injury, and as a sequel to some nervous system infections, this is the first case, to our knowledge, associated with pneumococcal meningoencephalitis.

The syndrome of deafness-dystonia is rare and refers to the association of hearing impairment and dystonia when these are dominant features of a disease. Known genetic causes include Mohr-Tranebjaerg syndrome, Woodhouse-Sakati syndrome, and mitochondrial disorders, but the cause frequently remains unidentified. The aim of the current study was to better characterize etiological and clinical aspects of deafness-dystonia syndrome. We evaluated 20 patients with deafness-dystonia syndrome who were seen during the period between 1994 and 2011. The cause was identified in only 7 patients and included methylmalonic aciduria, meningoencephalitis, perinatal hypoxic-ischemic injury, large genomic deletion on chromosome 7q21, translocase of inner mitochondrial membrane 8 homolog A (TIMM8A) mutation (Mohr-Tranebjaerg syndrome), and chromosome 2 open reading frame 37 (C2orf37) mutation (Woodhouse-Sakati syndrome). The age of onset and clinical characteristics in these patients varied, depending on the etiology. In 13 patients, the cause remained unexplained despite extensive work-up. In the group of patients who had unknown etiology, a family history for deafness and/or dystonia was present the majority of patients, suggesting a strong genetic component. Sensory-neural deafness always preceded dystonia. Two clinical patterns of deafness-dystonia syndrome were observed: patients who had an onset in childhood had generalized dystonia (10 of 13 patients) with frequent bulbar involvement, whereas patients who had a dystonia onset in adulthood had segmental dystonia (3 of 13 patients) with the invariable presence of laryngeal dystonia. Deafness-dystonia syndrome is etiologically and clinically heterogeneous, and most patients have an unknown cause. The different age at onset and variable family history suggest a heterogeneous genetic background, possibly including currently unidentified genetic conditions.

Actual indications for surgery in tuberculosis are limited to obtaining a diagnosis, acquiring tissue for culture studies, treating hydrocephalus, aspiring a brain abscess, and reducing intracranial pressure in patients with multiple tuberculomas. Tuberculosis-related movement disorders are usually treated pharmacologically. We report on a child affected by post-tubercular generalized dystonia, who progressed to status dystonicus (SD) and underwent stereotactic bilateral pallidotomy. After surgery, SD resolved, and drugs were rapidly tapered. The successful reversal of SD and the motor improvement observed in our patient demonstrate the safety, feasibility, and clinical efficacy of pallidotomy in post-tuberculous-meningoencephalitis dystonia and SD.
