Torticollis

Abstract: We reviewed detailed clinical features of 266 patients with idiopathic cervical dystonia, commonly called spasmodic torticollis. Mean age at onset (41 years), female-to-male ratio (1.9:1), clustering of onset between ages 30 and 59 (70%), familial history of dystonia (12%), and remissions (9.8%) were similar to those found in previous studies. In contrast to the single prior large clinical study of this disorder, no predominance of right-handers or significant thyroid disease was found. Pain, which occurred in 75% of patients and contributed to disability score (p less than 0.01), distinguishes this syndrome from all other focal dystonias. Pain was also strongly associated with constant (vs. intermittent) head turning, severity of head turning, and presence of spasm. Eighty-three percent of patients had deviation of the head of greater than 75% of the time when sitting with the head unsupported (constant head deviation at rest). Of the 97% who had head turning, 81% also had head tilting in various combinations. The 23% with hand tremor had an older age at onset (mean, 46 vs. 41 years; p less than 0.05). An earlier age at onset (p less than 0.05) was seen in patients with a family history of dystonia (mean, 36 years), with trauma shortly preceding symptoms (mean, 36 years), with a change in the direction of head turning (mean, 30 years), and with remissions (mean, 33 years). Jerky movements or forced transient spasms of the head occurred in 62% of the patients, and these patients would be the ones for whom the designation "spasmodic torticollis" could logically apply.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract: We enrolled 55 patients in a double-blind, placebo-controlled, parallel design study of the effectiveness of botulinum toxin (Botox) injections for the treatment of spasmodic torticollis. Patients received a standard series of injections, either placebo or Botox. We determined the sites of injection and dose per muscle by the nature of head deviation. Compared with placebo, Botox produced statistically significant improvement in the severity of torticollis, disability, pain, and degree of head turning. There were no serious side effects. During the double-blind phase, 61% of patients injected with Botox improved; 74% of patients subsequently improved during a later open phase at a higher dose of Botox. Direction of head turning, severity of torticollis, and presence or absence of jerky movements did not significantly influence the response rate. We conclude that Botox is a valuable treatment for spasmodic torticollis.

Abstract: Objective. We sought to describe the clinical presentation of patients with retropharyngeal abscess (RPA), utility of imaging studies, and implications on management. Methods. A retrospective chart review was performed at a tertiary-care, pediatric hospital with cases identified by a discharge diagnosis of RPA; posttraumatic RPA cases were excluded. Patients without confirmatory radiographic findings, fluoroscopy, or computed tomography (CT) were excluded. Results. Sixty-four cases involving 64 patients were studied. The median age of the patients was 36 months; 48 (75%) of the 64 patients were younger than 5 years. The most common chief complaints were neck pain (38%), fever (17%), sore throat (17%), neck mass (16%), and respiratory distress or stridor (5%). In 29 children (45%), it was noted that there was limitation of neck extension, in 23 (36.5%) torticollis, and in 8 (12.5%) limitation of neck flexion. The physical examination revealed stridor with wheezing in only 1 patient (1.5%) and wheezing in 1 other (1.5%). Twenty-seven patients (42%) underwent surgery; 37 (58%) were treated with antibiotics only. Performance of a surgical procedure was significantly associated with CT scan findings. Ten (37%) of 27 patients with defined abscess on CT scan were treated with antibiotics alone. There were no treatment failures in either the antibiotic-only group or the antibiotics-plus-surgery group. Conclusions. Children with RPA present with limitation of neck movement, especially difficulty extending their neck to look up. They rarely present with respiratory distress or stridor. CT scan is useful to distinguish patients with RPA from those with retropharyngeal cellulitis. Most patients with retropharyngeal cellulitis and some with RPA can be treated successfully without surgery.
