Torticollis as a sign of spinal tuberculosis.

Bone localization of tuberculosis mainly affects the thoracolumbar spine. The cervical spine is rare. Its diagnosis is often late which exposes to great instability and potentially serious complications. We report the case of a 12-year old girl with no medical history, showing torticollis and high temperature without neurological complication. In the physical examination, he had torticollis and pain in the third, fourth and fifth cervical vertebra. When the biopsy was performed, we find an inter apophysis (between C7 and D1) collection. The histological examination confirmed the diagnosis of apophysis tuberculosis. The management based on tuberculosis chemotherapy and immobilization started as soon as possible.

Atlantoaxial rotatory fixation in a case of tubercular lymphadenitis.

Atlantoaxial fixation is a relatively rare cause of torticollis which may be easily missed in practice. Early diagnosis is important as this indicates a compromised atlantoaxial complex with the potential to cause neural damage or even death. Here, we report a case of atlantoaxial rotatory fixation in a 13 yr old male with torticollis for two years and history of defaulting treatment for tubercular lymphadenitis. In this case, the odontoid peg view revealed asymmetric distance between the odontoid and lateral mass of atlas which was confirmed with Fluoroscopy and Computed Tomography (CT) scan. Magnetic Resonance Imaging (MRI) was also done which showed hyperintensity in alar ligaments with posterior inclination of the odontoid peg along with cervical lymphadenopathy.

The importance of early diagnosis and appropriate treatment in Grisel's syndrome: report of two cases.

Grisel's syndrome designates subluxation of atlanto-axial joint unrelated to trauma or bone disease. Atlanto-axial subluxation is seen after the upper neck inflammatory processes of head and neck region. Moreover, this rare clinical entity has been observed after various otolaryngological surgical approaches including adenoidectomy, tonsillectomy and mastoidectomy. An 8-year-old girl and 14 year-old boy presented with complaints of painful torticollis. The first patient was operated on at another health center due to adenoid hypertrophy. She was referred to our clinic on the postoperative 5th day with painful torticollis. The diagnosis was established by computerized tomography and three-dimensional reconstructions. The second patient had a history of throat infection. Radiological investigation demonstrated atlantoaxial subluxation. The patients were treated with external fixation, antibiotic therapy, muscle relaxants, and anti-inflammatory therapy. Early diagnosis and appropriate treatment resulted in a good outcome in our patients. Grisel's syndrome must be considered in the differential diagnosis in children with painful torticollis associated with upper respiratory tract infection and after various otolaryngological surgical procedures. We report two cases of Grisel's syndrome which emphasize on the importance of early diagnosis for appropriate and successful treatment.

Torticollis in mice intravenously infected with Mycobacterium tuberculosis.

Female BALB/cAnNCrl (n = 170; age, 6 to 9 wk) mice were infected by intravenous inoculation of 5 × 10(6) cfu Mycobacterium tuberculosis strain Erdman (ATCC 35801). Between day 52 and 5 mo after infection, 10 of the 170 mice infected according to this protocol developed torticollis, including mice in treatment groups that received combination antibiotic therapy of rifampin-pyrazinamide or moxifloxacin-rifampin-pyrazinamide. Torticollis did not develop in mice receiving isoniazid- rifampin-pyrazinamide therapy, nor was it present in the cohort of aerogenically infected mice. Affected mice were euthanized, and complete necropsy evaluation was performed on 4 mice. Gross necropsy evaluation revealed typical tuberculosis lesions in lungs of infected mice. Histologic evaluation of tissues revealed granulomatous otitis media with intralesional acid-fast bacilli consistent with Mycobacterium tuberculosis. These cases represent an unusual finding specific to the intravenous mouse model of Mycobacterium tuberculosis and may represent a model of a similar condition in humans that is known as tuberculous otitis media.

Nontraumatic subluxation of the atlanto-axial joint as rare form of acquired torticollis: diagnosis and clinical features of the Grisel's syndrome.

STUDY DESIGN: Case report and review of the literature. OBJECTIVE: We report a case of Grisel's syndrome with a delayed diagnosis. The patient's first presentation in our pediatric orthopedics department was 2 month after surgery (cochlea implantation) with a persistent torticollis. Radiographs revealed a subluxated atlantoaxial joint. We treated our patient with manual repositioning and calculated antibiotics, which lead to a restitutio ad integrum within a short time. SUMMARY OF BACKGROUND DATA: Grisel's syndrome is synonymous with rare nontraumatic, rotational subluxation of the atlantoaxial joint (C1-C2). All formerly reported cases showed a clear association to infection or were related to head and neck surgery. Still, there is a lack of understanding about pathogenetic features and causative agents. In 1977 Fielding proposed a classification of the atlantoaxial subluxation and stage-related therapy was recommended. METHODS: Our patient was a 11-year-old girl with a torticollis after insertion of a cochlea implant. After surgery, physiotherapy was performed because of her wryneck. As the symptoms did not improve, she was presented in our clinic. Our radiographs revealed a subluxated atlantoaxial joint. RESULTS: In general anesthesia we performed a manual repositioning and she was temporarily immobilized with a cervical collar for 2 weeks. In addition, we administered calculated antibiotics, although CRP and leukocytes were not elevated. The follow up showed a good repositioning within a short time. CONCLUSION: At least in this case, our treatment led to shorter recovery and avoidance of halo fixation. Our new therapeutic approach to patients with Grisel's syndrome might lead to a shorter recovery.

Nervous signs associated with otitis and cranial osteomyelitis and with Ornithobacterium rhinotracheale infection in red-legged partridges (Alectoris rufa).

A case of nervous signs in red-legged partridges (Alectoris rufa) associated with a severe otitis and osteomyelitis is reported. The outbreak was characterized by abnormal head position, torticollis and difficulty in standing, walking and flying. Pathological, microbiological and molecular genetic data supported an association with Ornithobacterium rhinotracheale (ORT) infection. Clinical signs persisted for several days and were accompanied by weight loss leading to death. Morbidity was approximately 20% and most birds died if untreated. Lesions were mainly characterized by a severe osteomyelitis of the cranial bones and purulent inflammation of the external, middle and inner ears. O. rhinotracheale was isolated from ear samples, skull and brain stem in pure culture. Genetic characterization by pulsed-field gel electrophoresis of the clinical isolates showed that the outbreak was caused by a single strain of ORT. This appears to be the first report of otitis associated with ORT in an avian species.

Medically treated paravertebral Brucella abscess presenting with acute torticollis: case report.

BACKGROUND: Atlantoaxial subluxation secondary to a paravertebral (retropharyngeal) abscess is a well known but rare event in children. CASE DESCRIPTION: The authors describe the clinical and radiologic findings of a case of 6-year-old child who presented with acute torticollis (duration, 4 days). Type 2 atlantoaxial rotatory fixation and upper cervical paravertebral (retropharyngeal) abscess were diagnosed on radiologic examination. Laboratory test results showed positive agglutination titer for Brucella melitensis, in the rate of 1/640 dilution. This is the first reported case of Brucella-related atlantoaxial subluxation in a child in the pediatric literature. The patient was treated successfully with anti-inflammatory drugs, Brucella-specific antibiotic regimen, and Philadelphia collar application. Possibly, effusion of the atlantoaxial joint, due to Brucella infection, led to the laxity of the ligaments and contributed to subluxation. CONCLUSIONS: Brucella abscess should be kept in mind for the differential diagnosis of retropharyngeal mass, and the torticollis may be the only presenting sign. The authors recommend a trial of medical treatment with adequate dosages for a reasonable length of time and immobilization before considering surgical intervention for the spinal paravertebral Brucella abscess and related atlantoaxial subluxation.

Wry necks associated with Mycoplasma meleagridis infection in a backyard flock of turkeys.

Two 5-week-old bronze turkeys were submitted with crooked necks that could not be straightened. Both birds were serologically and culturally positive for Mycoplasma meleagridis (MM). Histologically, there were lymphoid follicles in the cranial thoracic and cervicoclavicular air sacs, and inflammatory changes in the cartilage of some cervical vertebrae. This appeared to be a case of MM-associated wry necks.
