Abstract
Background Dystonias are hyperkinetic movement disorders characterized by involuntary muscle contractions resulting in abnormal torsional movements and postures. Recent neuroimaging studies in idiopathic craniocervical dystonia (CCD) have uncovered the involvement of multiple areas, including cortical ones. Our goal was to evaluate white matter (WM) microstructure in subjects with CCD using diffusion tensor imaging (DTI) analysis. Methods We compared 40 patients with 40 healthy controls. Patients were then divided into subgroups: cervical dystonia, blepharospasm, blepharospasm + oromandibular dystonia, blepharospasm + oromandibular dystonia + cervical dystonia, using tract-based spatial statistics. We performed a region of interest-based analysis and tractography as confirmatory tests. Results There was no significant difference in the mean fractional anisotropy (FA) and mean diffusivity (MD) between the groups in any analysis. Discussion The lack of DTI changes in CCD suggests that the WM tracts are not primarily affected.

Abstract
OBJECTIVE The purpose of this case report is to describe the care and outcomes of a patient with cervical dystonia who was treated using chiropractic and other alternative medicine interventions. CLINICAL FEATURES A 59-year-old woman had an 11-year history of cervical dystonia. She had an uncontrollable 60° leftward head rotation upon shutting her eyes and had spasmodic contractions that caused fatigue. INTERVENTION AND OUTCOME The management consisted of blue-lensed glasses, vibration stimulation, spinal manipulation, and eye-movement exercises. Within the first week of treatment, she had a reduction in symptoms, which was documented using a functional numeric scale, and improved posture, which was assessed using measurements from her midsternal line to the center of her chin. CONCLUSION This patient with cervical dystonia responded to the use of conservative, nonpharmacological treatment procedures that consisted of chiropractic care using a functional neurologic approach aimed at improving her spasmodic contractions and function.

Abstract
UNLABELLED DYT-1 dystonia is the most common primary dystonia seen in childhood. It is an autosomal dominantly inherited disorder caused by deletion of a GAG triplet in exon 5 of the DYT1 gene. It characteristically starts in a distal limb during late childhood, subsequently spreads to involve other body regions sparing oromandibular muscles. However, clinical presentation can vary remarkably with respect to age, site of onset and progression. In this study we present three early-onset DYT-1 dystonia patients who are atypical according to age of onset and localization. Dystonia has started at 2, 3 and 7years of age and generalized to involve other limbs in all patients and also oromandibular muscles in one patient. None of them have benefited from medical treatments including L-dopa. All had normal brain MRI scan, a history of normal birth without significant perinatal asphyxia, infection or trauma and all are neurodevelopmentally otherwise normal. CONCLUSION In children with dystonia; if brain imaging is unremarkable and when there is no history of CNS disorders such as perinatal asphyxia, infections, drug exposure or trauma; genetic analysis for GAG deletion of DYT-1 gene may be performed even if dystonia starts at a very young age or it spreads to involve oromandibular muscles.

Abstract
Benign hereditary chorea (BHC, MIM 118700) is a rare autosomal dominant disorder manifesting with chorea in conjunction with hypothyroidism and respiratory problems, a triad also named "brain-lung-thyroid syndrome". BHC is characterized by childhood onset with minimal or no progression into adult life and normal cognitive function. The genetic basis of BHC has been partially resolved, when mutations in the TTF1 gene on chromosome 14q13 encoding the thyroid transcription factor-1 have been identified in a number of BHC patients, suggesting that aberration of TTF1 transcriptional function or haploinsufficiency is associated with this disorder. TTF1 (also known as TITF1, TEBP or NKX2-1), belonging to the NKX2 homeodomain transcription factor family, has been implicated in several important molecular pathways essential for brain, thyroid and lung morphogenesis. Clinical evaluation of TTF1 gene mutations carrier patients exposed the involvement of each of the triad's components characterized by heterogeneity between index cases and even within families. This review highlights the current updates on expanded clinical aspects of BHC, imaging and treatment experience, its genetic markers, proposed molecular mechanisms, animal models and link to cancer.

Abstract
To assess RNAi mediated inhibition of the expression of wt-DYT1 on H(2)O(2)-induced toxicity in NIH 3T3 cells and primary cortical neurons. To detect the function of wild-type Torsin A and the effect of SiRNA on the wt-DYT1 gene. The shRNA expression vector was constructed by ligating annealed complementary shRNA oligonucleotides into the down-stream of the human U6 promoter (PU6) of the RNAi-ready pSIREN-Shuttle vector. Then, the pSIREN-Shuttle-DYT1-shRNA cassette was ligated to Adeno-X Viral DNA to construct the recombinant adenoviral vector pAd-DYT1-shRNA. Cultured cerebral cortical neurons and NIH 3T3 cells were transfected with pAd-DYT1-shRNA and pSIREN-Shuttle-DYT1-shRNA. We evaluated NIH 3T3 cells and neurons in the presence of oxidative stress using a TUNEL assay under different conditions. The knockdown efficacy of the DYT1 was confirmed by real-time RT-PCR and Western Blot analysis. After exposure to H(2)O(2,) the quantity of NIH 3T3 cells transfected with pSIREN-Shuttle-DYT1-shRNA, which stained positively in the TUNEL assay, was significantly higher than the cells transfected with pSIREN-Shuttle-negative control-shRNA. (44.85 +/- 1.81% vs. 8.98 +/- 2.73%, t = 26.168). There were significantly more apoptotic neurons infected with pAd-DYT1-shRNA (45.63 +/- 7.53%) than neurons infected with pAd-X-negative control-shRNA (17.33 +/- 2.43%) (t = 9.816). The observed silencing of wild-type Torsin A expression by DYT1-shRNA was sequence-specific. RNAi-mediated inhibition of the expression of wild-type Torsin A increases apoptosis caused by oxidative stress. It is reasonable to consider that wild-type Torsin A has the capacity to protect cortical neurons against oxidative stress, and in the development of DYT1-delta GAG-dystonia the neuroprotective function of wild-type Torsin A may be compromised.

Abstract
BACKGROUND The clinical phenotype of DYT6 consists mainly of primary craniocervical dystonia. Recently, the THAP1 gene was identified as the cause of DYT6, where a total of 13 mutations have been identified in Amish-Mennonite and European families. METHODS We sequenced the THAP1 gene in a series of 362 British, genetically undetermined, primary dystonia patients (78 with focal, 186 with segmental, and 98 with generalized dystonia) and in 28 dystonia-manifesting DYT1 patients and 176 normal control individuals. RESULTS Nine coding mutations were identified in the THAP1 gene. Two were small deletions, 2 were nonsense, and 5 were missense. Eight mutations were heterozygous, and 1 was homozygous. The main clinical presentation of cases with THAP1 mutations was early-onset (<30 years) dystonia in the craniocervical region or the limbs (8 of 9 patients). There was phenotypic variability with laryngeal or oromandibular dystonia present in 3 cases. Four of 9 THAP1 cases developed generalized dystonia. CONCLUSIONS The number of THAP1 mutations has been significantly expanded, indicating an uncommon but important cause of dystonia. Coding mutations account for 9 of 362 dystonia cases, indicating a mutation frequency of 2.5% of dystonia cases in the population that we have screened. The majority of cases reported here with THAP1 mutations had craniocervical- or limb-onset segmental dystonia, but we also identified 1 homozygous THAP1 mutation, associated initially with writer's dystonia and then developing segmental dystonia. Three of our patients had a nonsense or frameshift THAP1 mutation and the clinical features of laryngeal or oromandibular dystonia. These data suggest that early-onset dystonia that includes the involvement of the larynx or face is frequently associated with THAP1 mutations.
