Retrocollis (RC) is a form of cervical dystonia (CD) that produces patterned, repetitive muscle contractions that result in neck extension. We performed a review of consecutive CD patients seen in our Division over a 15-year period. Out of 399 CD patients, 59 (14.8%) had features of RC. Pain was very frequently reported among patients (∼80%). RC was frequently associated with neuroleptic exposure (20.3%) and a history of head/neck trauma (23.7%). Of patients injected with botulinum toxin type A… Expand
Predictable variables for short- and long-term botulinum toxin treatment response in patients with cervical dystonia
TLDR
It is suggested that the greater CD severity the more likely patients will respond to BTX-A, and intake of oral medication previously to BTx-A injection and higher Tsui scores were predictors of favorable response. Expand
Selective peripheral denervation for the treatment of spasmodic torticollis: long-term follow-up results from 648 patients
TLDR
SPD is an effective surgical method for patients with ST and should be recommended if conservative therapy does not offer satisfactory relief of symptoms, according to the Toronto Western Spasmodic Torticollis Rating Scale. Expand

TLDR
This review will highlight the following therapeutic applications of BoNT in conditions associated with PD: limb dystonia, blepharospasm and lid apraxia, bruxism, cervical dySTONia (anterocollis), camptocormia, hand and jaw tremor, rigidity, freezing of gait, sialorrhea, dysphagia (achalasia), seborrhea, hyperhidrosis, overactive bladder, and constipation.

TLDR
A 42-year-old farmer developing persistent mid-facial segmental pain and Meige's syndrome several months after suffering facial trauma and a fracture of the nose was capable of suppressing his facial pain by performing a ritual that included forcefully tilting his head backwards, lowering of his eyelids and applying strong pressure to his nasion.

TLDR
Acute viral torticollis occurring in a young adult with associated symptoms of fever, headache, nausea, and vomiting presents a diagnostic challenge in excluding the possibility of meningitis. Expand
Zur Phänomenologie der zervikalen Dystonien Vorschlag einer neuen Behandlungsstrategie mit Botulinumtoxin The Phenomenology of Cervical Dystonia Proposed New Treatment Strategy with Botulinum Toxin
TLDR
It was shown that in lateral flexion and in rotation, in 1/5 of patients the disorder affect-ed only muscles which work on atlanto-occipitaljoints (latero- or torticaput), and in a further 1/ 5 it affected only musclesWhich work on the cervi-cal spine ( latero-or torticollis), and differentiation be-tween laterocollis and laterocaput is clinically possible.

Axial postural deformities in Parkinson’s disease
TLDR
Radiological examination demonstrated that Pisa syndrome was different from de novo degenerative scoliosis and camptocormia not typical of adult onset degenerative kyphosis and fixed bony changes were rare. Expand
Postural deformities in Parkinson's disease
TLDR
Improved understanding of the mechanisms underlying postural deformities in PD might ultimately lead to more effective management strategies for these disabling and drug-refractory complications. Expand

TLDR
This chapter will review and assess the clinical utility of the various botulinum products in neuromuscular disorders and the cosmetic use of the neurotoxin. Expand

TLDR
Botulinum toxin is helpful in the management of blepharospasm, bruxism, camptocormia, cervical dystonia including anterocollis, sialorrhea, seborrhea, and overactive bladder. Expand

Post-traumatic Cervical Dystonia: A Distinct Entity?
TLDR
CD-I and CD-T are clinically similar and Trauma may be a triggering factor in CD but this was only supported by non-significant trends in its earlier age of onset. Expand
Epidemiology and outcome of cervical dystonia (spasmodic torticollis) in Rochester, Minnesota
TLDR
The natural history of cervical dystonia (spasmodic torticollis) was investigated in a population‐based study in Rochester, Minnesota, and three cases of intracranial aneurysm were confirmed, two of which produced fatal subarachnoid hemorrhage. Expand
Cervical dystonia following peripheral trauma--a case-control study.
TLDR
A retrospective study of the clinical characteristics of the 16 patients with early post-traumatic CD (CD-PT) in comparison with the 52 patients reporting no antecedent trauma ( CD-NT) was performed, finding the CD-PT group had a significantly increased frequency of laterocollis, significantly more reported pain and more reported depression.

Postoperative Cervical Dystonia: Is It an Occult Injury to the Corticospinal Tracts?
TLDR
Cervical dystonia, especially in its mild form, is likely more common than currently reported and may be a complication that should be discussed preoperatively with patients suffering from spinal cord compression. Expand
Safety and efficacy of NeuroBloc (botulinum toxin type B) in type A-responsive cervical dystonia.
TLDR
Improvements associated with BoNT/B treatment were greatest for patients who received the 10,000-U dose, and Botulinum toxin type B (NeuroBloc) is safe and efficacious at 5,000 U and 10, thousand U for the management of patients with cervical dystonia. Expand
Pain in spasmodic torticollis
TLDR
It is suggested that pain associated with spasmodic torticollis does not arise in muscles alone, and it is hypothesised that central mechanisms are also involved. Expand
Comparison of botulinum toxin serotypes A and B for the treatment of cervical dystonia
TLDR
Both serotypes of botulinum toxin (BoNTA and BoNTB) had equivalent benefit in subjects with cervical dystonia at 4 weeks and BoNTA had fewer adverse events and a marginally longer duration of effect in subjects showing a clinical response. Expand
Botulinum toxin treatment in atypical parkinsonian disorders associated with disabling focal dystonia
TLDR
It is suggested that BtxA therapy may represent an effective means of alleviating disabling focal dystonia in different APDs, particularly in early stage APD with disabling limb dystonian symptoms, and local B TXA injections may result in functional improvement. Expand
