Grisel syndrome as a complication of Kawasaki disease: a case report and review of the literature

Torticollis in incomplete Kawasaki disease: a case of atlantoaxial rotatory fixation

Various respiratory, musculoskeletal, gastrointestinal, neurological, and urinary complications have been reported in Kawasaki disease. Here, we describe a rare case of atlantoaxial rotatory fixation (AARF) associated with incomplete Kawasaki disease. The case is of a healthy 4-year-old Japanese boy who had a high-grade fever, lymphadenopathy, and torticollis diagnosed with incomplete Kawasaki disease. Intravenous high-dose immunoglobulin and oral aspirin quickly resolved his fever and improved his lymphadenopathy, but torticollis remained. On orthopaedic examination, torticollis was observed with a marked restriction of rotation, and an open-mouth anteroposterior cervical radiograph and a CT scan confirmed rotational dislocation at the dens axis (AARF). Cervical collar fixation was immediately started, and the torticollis gradually normalized within a week. AARF is defined as torticollis due to dislocation or subluxation of the atlantoaxial joint. The diagnosis of AARF is difficult with routine plain cervical radiographs in 2 directions alone, and an additional cervical open-mouth anteroposterior radiograph and a CT scan aid the diagnosis. AARF associated with Kawasaki disease is uncommon, and only 24 cases have been reported in the literature. AARF may occur in Kawasaki disease patients with cervical lymphadenopathy. Still, torticollis is often transient and may not be recognized or ignored by family doctors and paediatricians. Reduction of the atlantoaxial joint can often be achieved spontaneously or with conservative treatment such as a collar or neck traction, but treatment is difficult if the diagnosis is delayed. Therefore, family doctors and paediatricians need to suspect the onset of AARF if torticollis is observed during treatment for Kawasaki disease, perform plain cervical radiographs including open-mouth anteroposterior view and a CT scan of the cervical spine, and have orthopaedists immediately intervene to avoid invasive surgery.

Unusual Manifestations of Kawasaki Disease in the COVID Era: A Case Series and Review of the Literature

Kawasaki disease (KD) is an acute medium-vessel vasculitis, mainly affecting infants older than six months and children under five years. It predisposes to the development of coronary artery aneurysms and constitutes the leading cause of acquired heart disease in children. Its diagnosis is based on clinical criteria, namely, fever lasting for ≥ five days together with at least four of the five principal clinical features of the disease. Occasionally, children with KD present with fever, but they fulfill only some of the five principal criteria, and this is described as incomplete KD. Furthermore, "atypical" KD is a term that is usually used for cases that appear with rather unusual clinical manifestations, which complicate clinical judgment and may delay diagnosis and treatment. In this case series, we present four cases of KD with rather unusual clinical features: a five-year-old boy with lobar pneumonia, a six-year-old girl with orange-brown chromonychia appearing on the 10th day of the disease, a 2.5-month-old infant with prolonged fever and urinary tract infection, and an 18-month-old infant with refractory KD and high suspicion of multisystem inflammatory syndrome in children (MIS-C). A literature review on the unusual manifestations of atypical KD was performed to identify clinical findings that must alert the clinician to consider this clinical entity.

French national diagnostic and care protocol for Kawasaki disease

Kawasaki disease (KD) is an acute vasculitis with a particular tropism for the coronary arteries. KD mainly affects male children between 6 months and 5 years of age. The diagnosis is clinical, based on the international American Heart Association criteria. It should be systematically considered in children with a fever, either of 5 days or more, or of 3 days if all other criteria are present. It is important to note that most children present with marked irritability and may have digestive signs. Although the biological inflammatory response is not specific, it is of great value for the diagnosis. Because of the difficulty of recognising incomplete or atypical forms of KD, and the need for urgent treatment, the child should be referred to a paediatric hospital as soon as the diagnosis is suspected. In the event of signs of heart failure (pallor, tachycardia, polypnea, sweating, hepatomegaly, unstable blood pressure), medical transfer to an intensive care unit (ICU) is essential. The standard treatment is an infusion of IVIG combined with aspirin (before 10 days of fever, and for a minimum of 6 weeks), which reduces the risk of coronary aneurysms. In case of coronary involvement, antiplatelet therapy can be maintained for life. In case of a giant aneurysm, anticoagulant treatment is added to the antiplatelet agent. The prognosis of KD is generally good and most children recover without sequelae. The prognosis in children with initial coronary involvement depends on the progression of the cardiac anomalies, which are monitored during careful specialised cardiological follow-up.

Clinical Features of Kawasaki Disease With Atlantoaxial Rotatory Fixation

PURPOSE

Atlantoaxial rotatory fixation (AARF) is a rare complication of acute Kawasaki disease (KD). Early diagnosis and intervention are important for AARF because delayed diagnoses may incur neurological sequelae. However, previous studies on AARF associated with KD are limited, and its clinical characteristics and course are unknown. This study aimed to examine the clinical features and treatment course of KD with AARF using a Japanese national inpatient database.

METHODS

Using the Diagnosis Procedure Combination database, we identified KD patients who received intravenous immunoglobulin (IVIG) treatment between July 2010 and March 2020. The clinical characteristics of KD patients with AARF and their risk factors were evaluated using multivariable logistic regression analysis. We also examined the relationship between AARF, the proportion of coronary artery abnormalities (CAAs), IVIG resistance, length of stay and medical costs.

RESULTS

We identified 71,913 patients with KD, 166 of whom had AARF. The AARF group had older age, heavier bodyweight and atypical KD. In multivariable analysis, AARF was associated with older age [odds ratio (OR): 1.24; 95% confidence interval (CI): 1.19-1.29], lower body mass index (OR: 0.89; 95% CI: 0.82-0.96) and atypical KD (OR: 1.95; 95% CI: 1.12-3.40). AARF was not associated with CAAs (OR: 0.73; 95% CI, 0.23-2.32) and IVIG resistance (OR: 1.05; 95% CI, 0.74-1.49). However, AARF was associated with higher medical costs (difference, US$1064; 95% CI: 346-1781) and longer hospital stay (difference, 3.1 days; 95% CI: 1.7-4.4).

CONCLUSION

AARF in patients with acute KD should be considered if cervical symptoms present in older patients with atypical KD.

Unusual presentation of an unusual disease: A very delayed diagnosis of Grisel's syndrome

Grisel’s syndrome (GS) is a rare syndrome which refers only to non-traumatic atlantoaxial subluxation. This syndrome predominantly occurs in young children following an upper respiratory infection or otolaryngologic procedures. An eight-year-old girl with a delayed diagnosis of GS was admitted to our outpatient clinic with complaints of painful torticollis and neck stiffness. Three-dimensional computed tomography revealed rotatory atlantoaxial subluxation. After consulting with the neurosurgery department, the patient underwent surgery. The significance of this patient was that she was unable to be diagnosed early and atlantoaxial subluxation remained hidden for five years without any complications. In conclusion, this rare case highlights the importance of delayed diagnosis of GS and clinicians should be aware of this syndrome.

Grisel's Syndrome in Children: Two Case Reports and Systematic Review of the Literature

Background and Objective. Grisel's syndrome is a rare syndrome characterized by nontraumatic rotatory subluxation of the atlantoaxial joint. It usually affects children and typically presents with torticollis after ear, nose, and throat (ENT) surgery or head and neck infections. In the pediatric literature, there is only a small amount of available data; moreover, no systematic review has been previously done with focus on the pediatric population. We report our experience of two cases, and we provide a systematic review on Grisel's syndrome in children in order to offer a deeper insight about its clinical presentation, its current diagnosis, and principles of treatment. Case Reports and Review. We describe two boys of 9 and 8 years old, who developed atlantoaxial subluxation after adenoidectomy. Considering the early diagnosis, a conservative treatment was chosen, with no recurrence and no sequelae at follow-up. We identified 114 case reports, of which 90 describe children, for a total of 171 pediatric patients. Of the 154 cases in which cause was reported, 59.7% presented a head and neck infection and 35.7% had previous head and neck surgery. There is no sex prevalence (49.7% males versus 50.2% females). Mean delay in diagnosis is 33 days. Eight % of the patients had neurological impairment of the 165 cases which mentioned treatment, 96% underwent a conservative treatment, of whom the 8.8% recurred with the need of surgery. As a whole, 12% underwent surgery as a first- or second-line treatment. 3 6% of the patients whose follow-up was reported developed a sequela, minor limitation of neck movement being the most frequent. Conclusion. Grisel's syndrome should be suspected in children with painful unresponsive torticollis following ENT procedures or head and neck inflammation. CT scan with 3D reconstruction is the gold standard for diagnosis, allowing the identification of the subluxation and the classification according to the Fielding–Hawkins grading system. Surgical treatment is indicated in case of high-grade instability or failure of conservative treatment. Review of the literature shows how early diagnosis based on clinical and radiological evaluation is crucial in order to avoid surgical treatment and neurologic sequelae.

Grisel's syndrome: a case report on this rare pediatric disease and its anesthetic challenges

Background

Grisel’s syndrome is a non-traumatic atlantoaxial subluxation associated with inflammatory conditions of the head and neck, which occurs primarily in children. Increased flexibility of the ligaments during inflammation is implicated in the pathogenesis of the subluxation between the axis and atlas. The potential sequelae may be severe, and early diagnosis and treatment of Grisel’s syndrome can prevent tragic outcomes.

Case presentation

We present a case of torticollis in an 8-year-old child. She had a two-week history of a streptococcal throat infection. The patient was treated with several different methods of conservative care, including muscle relaxation, cervical halter traction, and Halo application. However, the torticollis persisted. The patient then required surgical correction involving cervical spine fusion. She had no complications and experienced no reoccurrence of the torticollis to date.

Conclusion

Grisel’s syndrome is a pathology for which conservative management is successful in most cases. Cases requiring surgical intervention are rarely documented in the literature. Our case is significant, as in spite of aggressive conservative management, the patient required surgical correction. Patients requiring surgical management of Grisel’s syndrome may require additional anesthetic exposure for diagnostic interventions like magnetic resonance imaging or neck manipulations for closed reduction. We discuss the features of Grisel’s syndrome and specific anesthetic management considerations for procedures such as magnetic resonance imaging, application of cervical traction, and surgical correction of torticollis.

Grisel's syndrome in Kawasaki disease

BACKGROUND

Approximately 50-70% of patients with Kawasaki disease (KD) could present with cervical lymphadenopathy associated with deep neck inflammation, which may result in Grisel's syndrome (GS). Given the possibility of neurological impairment owing to GS, it is important to understand the disease profile in KD. Therefore, we carried out this study to investigate this possible complication of KD, with the aim of improving pediatricians' recognition and awareness.

METHODS

Patients with KD complicated by GS in our hospital were retrospectively recruited for our study. The profiles of patients with GS (n = 10) were compared to those patients without GS (n = 1254). All the available literature describing these complications of KD was reviewed.

RESULTS

The incidence of GS in KD was 0.6% in our population. Compared to patients without GS, KD patients with GS were older, presented with a significantly lower male:female ratio, and a higher incidence of cervical lymphadenopathy, a higher level of neutrophil count, and erythrocyte sedimentation rate. Ten articles reporting 14 KD patients with GS were reviewed. Of the total 24 patients, GS affected 7 males and 17 females, aged from 3.5 to 9 years old. Encouragingly, no delayed diagnosis and treatment of KD was found, and all patients received conservative therapy for GS, without intravenous immunoglobulin resistance, coronary artery lesions, and neurological impairment.

CONCLUSIONS

GS is a rare complication of KD with an incidence of 0.6%, predominantly affecting older, female children. The overall outcome of this disorder in KD was satisfactory with conservative therapy. Pediatricians, especially pediatric surgeons, should recognize and be aware of this possible complication of KD to avoid misdiagnosis and overtreatment.

Kawasaki disease: characteristics, diagnosis, and unusual presentations

Introduction: Kawasaki disease (KD) is one of the commonest pediatric vasculitides and is associated with a significant risk of development of coronary artery abnormalities if left untreated. Areas covered: In this review, we have highlighted the incomplete and unusual presentations of KD and also emphasize the controversies pertaining to 2D echocardiography in KD. A PubMed search was performed regarding diagnosis and unusual presentations of KD. Expert opinion: Diagnosis of KD is essentially clinical and based on recognition of typical clinical features that may appear sequentially and all signs and symptoms may not be present at one point of time. There is no confirmatory laboratory test for diagnosis of this condition. Further complicating the picture is the fact that incomplete and atypical forms KD may be seen in up to 50% patients. Although 2D echocardiography continues to be the preferred imaging modality for cardiac assessment in patients with KD, it has its limitations.

Grisel's syndrome caused by Mycoplasma pneumoniae infection: a case report and review of the literature

BACKGROUND

Grisel's syndrome is a non-traumatic subluxation of the atlantoaxial joints, which is caused by an inflammatory process involving the upper neck. Torticollis, neck pain, and reduced neck mobility are the main clinical signs of presentation. Predisposing factors are trauma, hyperlaxity of the transverse and alar ligaments of the atlantoaxial joints, and surgical interventions carried out in this area. Several viral and bacterial pathogens have been reported as causative events of Grisel's syndrome, including Epstein-Barr virus, Kawasaki disease, Streptococcus pyogenes, Staphylococcus aureus, and other infectious agents. Grisel's syndrome linked to Mycoplasma pneumoniae infection as the trigger has not previously been reported. Mycoplasma pneumoniae is a small prokaryotic microbe and a frequent etiologic factor of respiratory tract infections and, less frequently, of extrapulmonary body organs. The recognition of the Grisel's syndrome is based on clinical and neuroradiological investigations, and early diagnosis and specific treatment are crucial to the successful outcome of the disease.

RESULTS

We report the case of an 8-year-old girl with Grisel's syndrome caused by an upper respiratory tract infection due to Mycoplasma pneumoniae. Diagnostic suspicion and treatment of Grisel's syndrome were established quickly by anamnestic and clinical data and confirmed by radiological findings. The girl was immediately treated with specific antibiotic therapy and cervical immobilization, thus preventing the most dangerous complications of the disorder.

CONCLUSION

Mycoplasma pneumoniae, among the other infectious agents, may be cause of scute torticollis and Gresel's syndrome.

Grisel Syndrome in Pediatric Age: A Single-Center Italian Experience and Review of the Literature

BACKGROUND

Nontraumatic atlantoaxial subluxation, also known as Grisel syndrome, is a rare disease that usually affects children. The typical presentation is torticollis in patients with a history of surgical operations or airway infections.

METHODS

We describe 5 patients with Grisel syndrome, referring to medical care for a torticollis, a few weeks after an airway infection, with no trauma associated. Radiologic confirmation of the diagnosis, with computed tomography and magnetic resonance imaging studies, was carried out.

RESULTS

The patients were treated with external immobilization for 3 months, followed by surgical fixation in the case of recurrence after collar removal or inveterate subluxation. We performed a review of the literature to define the best management of this disease.

CONCLUSIONS

Management of Grisel syndrome depends on the degree of subluxation basing on the Fielding and Hawkins classification. The initial nonsurgical management consists of close reduction and immobilization. Surgical fixation is indicated in cases of conservative treatment failure.

Torticollis as Presentation for Atypical Kawasaki Disease Complicated by Giant Coronary Artery Aneurysms

Kawasaki disease (KD) is an acute systemic vasculitis of childhood. The diagnosis can be made in a patient who presents with a prolonged high fever and meeting at least four of five criteria including polymorphous rash, mucosal changes, extremity changes (including swelling and/or palmar and plantar erythema), bilateral nonsuppurative conjunctivitis, and unilateral cervical lymphadenopathy. Atypical KD refers to patients who have not met the full criteria and in whom atypical features may be present. We discuss a case of a 6-year-old male who presented to the Emergency Department with torticollis. A series of investigations for elevated inflammatory markers revealed dilated coronary artery aneurysms on echocardiogram, and thus he was diagnosed with atypical KD. His only other criteria were bilateral nonsuppurative conjunctivitis and a prior brief febrile illness. He was treated with high-dose intravenous immune globulin (IVIG) and low-dose aspirin. Low-molecular-weight heparin and atenolol were added due to the presence of giant aneurysms.

Retropharyngeal involvement in Kawasaki disease--a report of four patients with retropharyngeal edema verified by magnetic resonance imaging

Kawasaki disease is an acute systemic vasculitis of childhood. The diagnosis is based on clinical criteria. Prognosis with adequate treatment is favorable. Untreated patients, however, may develop coronary manifestations predisposing to acute myocardial infarction. Retropharyngeal edema is a rare but known manifestation of Kawasaki disease. We present a case series of four Kawasaki patients presenting with clinical findings for retropharyngeal abscess and the magnetic resonance imaging findings of these patients, diagnosed during a six week period. To our knowledge, this is the first systematic report of cervical MRI findings of Kawasaki patients.

Nontraumatic atlantoaxial rotatory subluxation: grisel syndrome. Case report and literature review

Study Design Case report and literature review. Objective To describe a case of nontraumatic atlantoaxial rotatory subluxation (Grisel syndrome) and to review clinical and radiologic aspects, physiopathology, and treatment of this lesion. There is no well-established protocol in the management of patients without spontaneous reduction. The authors discuss the available strategies to achieve reduction and when to operate on these patients. Methods Case presentation of a 7-year-old patient who presented with torticollis ∼1 week after the onset of an upper airway infection. There was no history of head or neck trauma. Computed tomography demonstrated atlantoaxial rotatory subluxation and a normal atlantodental interval. Results The patient was treated with nonsteroidal anti-inflammatory drugs and antibiotics and by progressively increasing the soft cervical collar height. Clinical reduction of the subluxation occurred after 48 hours. He wore the rigid collar for 6 weeks. At that moment, the patient was completely asymptomatic and follow-up cervical spine radiograph demonstrated an anatomical C1-C2 relation. The patient was instructed to return to daily life activities in a gradual manner. Conclusions Grisel syndrome should be considered in the differential diagnosis of torticollis, especially in children. The management can be planned according to the classification of Fielding and Hawkins. The initial treatment involves medicines, injury reduction, and cervical spine immobilization. Surgical treatment is indicated only in cases of failure of conservative treatment, recurrences of subluxation, and irreducible subluxations.
