Project description:Introduction:Diffuse idiopathic skeletal hyperostosis of cervical spine can lead to dysphagia. Presentation of case:A 73-year-old male weighing 110 kg and diagnosed with diffuse idiopathic skeletal hyperostosis in cervical spine with dysphagia. Patient manifested local pain of neck, a gradual limitation of spinal mobility. The surgery decision was based on swallowing problems, not pain in the spine. Before surgery radiographs, magnetic resonance images, computed tomography of the cervical spine and gastroscopy were obtained. Osteophytes were removed from the anterior approach with present otolaryngologist by surgery. Discussion:In this case used gastroscopy, CT and MRI for diagnostics. During the procedure we had support otolaryngologist. The patient has not been found a stenosis spinal canal and neurological symptoms. We were removed the ostheophytes. Interbody implants have not been applied. Conclusion:Disc degeneration disease itself can be asymptomatic or not a dominant problem for the DISH patients. Clinical signs may pharyngoesophageal and tracheal compression, causing dysphagia, shortness of breath and stridor. In this case, the cervical spine was stability and not demonstrated a stenosis in the spinal canal. Isolate removing of the osteophytes without implants in DISH of cervical spine can be enough solution.

Project description:Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by anterior ossification of the spine and can lead to dysphagia and airway obstruction. The morphology of the newly formed bone in the cervical spine is different compared to the thoracic spine, possibly due to dissimilarities in local vascular anatomy. In this study the spatial relationship of the new bone with the arterial system, trachea and esophagus was analyzed and compared between subjects with and without DISH.Cervical computed tomography (CT) scans were obtained from five patients with dysphagia and DISH and ten control subjects. The location of the vertebral and carotid arteries, surface area of the hyperostosis and distance between the vertebral body and the trachea and esophagus was assessed in the axial view.The surface area of the newly formed bone was located symmetrically anterior to the vertebral body. The ossifications were non-flowing in the sagittal view and no segmental vessels were observed. Substantial displacement of the trachea/esophagus was present in the group with DISH compared to the controls.The hyperostosis at the cervical level was symmetrically distributed anterior to the vertebral bodies without a flowing pattern, in contrast to the asymmetrical flowing pattern typically found in the thoracic spine. The hypothesis that the vascular system acts as a natural barrier against new bone formation in DISH could be further supported with these findings. The significant ventral displacement of the trachea and esophagus may explain the mechanism of dysphagia and airway obstruction in DISH.

Project description:ObjectivesDiffuse idiopathic skeletal hyperostosis (DISH) has recurrently been associated with a rich diet (high in protein and higher trophic level foods); however, very few studies have investigated this link using carbon and nitrogen (δ13C and δ15N) stable isotope analysis. This paper explores the relationship between DISH and diet in two Roman urban communities by analyzing individuals with and without DISH.Materials and methodsδ13C and δ15N analysis carried out on collagen from 33 rib samples (No DISH: 27; early DISH: 4; DISH: 2) selected from individuals buried at the Romano-British site of Baldock (UK), 41 rib samples (No DISH: 38; early DISH: 3) from individuals from the Catalan Roman site of Santa Caterina (Barcelona, Spain). Additionally, six faunal samples from Baldock and seven from Santa Caterina were analyzed.ResultsStandardized human isotope data from Santa Caterina show high δ15N probably associated to a diet combining terrestrial resources and freshwater fish. In contrast, isotope results from Baldock suggest a terrestrial-based diet. Individuals with DISH do not show isotopic ratios indicative of rich diet and there is no correlation between stage of DISH development and δ13C and δ15N.ConclusionThe results of this study suggest that individuals with DISH followed a similar or isotopically similar diet as those individuals without DISH in Baldock and in Santa Caterina and therefore, while DISH may have been influenced by individual's dietary habits, this is not reflected in their isotopic signature.

Project description:BACKGROUND:Computed tomography (CT) analyses have reported that the prevalence of diffuse idiopathic skeletal hyperostosis (DISH) in Japan is 8.7-27.1%. However, these data were obtained using chest-abdominal CT, and no evaluations of sagittal, coronal, and axial images using whole-spine CT have been reported. The aim of this study was to investigate the prevalence and characteristic of DISH by whole spinal CT. METHODS:Participants were patients who had experienced trauma who had undergone whole-spine CT scanning based on the initial clinical practice guidelines for trauma in our institute from April 2015 to February 2018. The subjects were > 20 years old and 1479 were included in the analysis. The presence and distribution of DISH and clinical parameters such as age and sex were reviewed retrospectively according to the location of DISH. RESULTS:The overall prevalence of DISH was 19.5% (n = 289). Subjects with DISH were older than those without. DISH was located in the thoracic spine in 65.1% and thoracolumbar spine in 24.2% of patients. More than 80% of ligamentous ossifications associated with DISH occurred at T8 (n = 255, 88%), T9 (n = 262, 91%), and T10 (n = 247, 85%). Most of the ossification occurred to the right anterior of the vertebral body, and there were few ossifications in the areas in contact with the artery and vein. CONCLUSIONS:The prevalence of DISH based on whole-spine CT was 19.5%. Ossification was noted more often at T8, T9, and T10, and to the right anterior of the vertebral body. It is for the first time report that we have studied the location of ossification in detail using the axial images of whole spine CT. We hope this study will enhance the understanding of the characteristics of DISH.

Project description:BACKGROUND:Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by the ossification of vertebral bodies and peripheral entheses. However, variations in sacroiliac (SI) joint change in patients with DISH have not been fully clarified. The purpose of this study was to evaluate SI joint variation in patients with DISH in comparison with a non-DISH population. METHODS:A total of 342 SI joints in 171 patients (DISH+, n =?86; DISH-, n =?85) who had undergone lumbar spine surgery were analyzed by computed tomography examination. SI joint variations were classified into four types: Type 1, normal or tiny peripheral bone irregularity; Type 2, subchondral bone sclerosis and osteophytes formation; Type 3, vacuum phenomenon; and Type 4, bridging osteophyte and bony fusion. The type of bridging osteophyte in SI joints and the prevalence of ossification in each spinal segment from C1 to SI joint were also examined. RESULTS:The most common SI joint variation in the DISH+ group was bony fusion (Type 4), with 71.6% exhibiting anterior paraarticular bridging. On the other hand, SI joint vacuum phenomenon (Type 3) was the most frequent change (57.1%) in the DISH- group. The middle to lower thoracic spine and SI joints were highly affected in DISH and caused bony ankylosis. CONCLUSIONS:Anterior paraarticular bridging was the most common type of SI joint change in patients with DISH who underwent lumbar spine surgery. The present results regarding variations of SI joint changes in DISH should help understand the etiology of DISH.

Project description:IntroductionDiffuse idiopathic skeletal hyperostosis (DISH), or Forestier disease, is a condition characterized by calcification and ossification of ligaments and enthuses (ligament and tendon insertion sites), which mainly affect the vertebral column. The clinical manifestation of DISH is variable. Some patients can be completely asymptomatic, whereas others can complain of painful stiffness, decreased range of movement, and myelopathy symptoms. OPLL usually produce myelopathy symptoms. Combined of OPLL and DISH are rare case.IllustrationA 59 years old woman patient complained of neck and shoulder pain in the last 20 years ago, with decreased neck range of motion and dysphagia. There was no gross abnormality on patient's neck and back. Cervical x ray was showing a continuous ossification extending from the anterior surface of C2 to C7 in lateral radiograph. A similar ossification was also noticed on the posterior surface of the vertebral bodies from C2 to C6 abutting the spinal canal.DiscussionDespite striking abnormal appearance of cervical DISH and OPLL seen on radiologic examinations, absence of myelopathy is an indication to non-operative treatment. Presence of dysphagia was not an indication of surgery in this patient, as dysphagia was not severe and myelopathy was absent. Patient was observed during her clinical course to document the progression of myelopathy. Prophylactic surgery was not indicated for this patient, and progression of myelopathy during observation is an indication for surgical intervention.ConclusionDiffuse and large abnormalities in cervical area with normal neurological function is not indication for surgery. Selective treatment based on individual case.

Project description:Diffuse idiopathic skeletal hyperostosis (DISH) is a prevalent noninflammatory spondyloarthropathy characterized by ectopic mineral formation along the anterolateral aspect of the vertebral column, yet little is known about its underlying pathogenesis. Our objective was to evaluate the histopathological features and composition of ectopic mineral within spinal tissues affected by DISH in humans. Thoracic spine segments from six embalmed cadaveric donors (one female and five males; median age 82 years) meeting the radiographic diagnostic criteria for DISH were evaluated using radiological, histological, and physical analyses. Overall, the histological features of ectopic mineralization at individual motion segments were heterogeneous, including regions of heterotopic ossification and dystrophic calcification. Heterotopic ossifications were characterized by woven and lamellar bone, multifocal areas of metaplastic cartilage, and bony bridges along the anterior aspect of the intervertebral disc space. Dystrophic calcifications were characterized by an amorphous appearance, a high content of calcium and phosphorus, an X-ray diffraction pattern matching that of hydroxyapatite, and radiodensities exceeding that of cortical bone. Dystrophic calcifications were found within the anterior longitudinal ligament and annulus fibrosus in motion segments both meeting and not meeting the radiographic criteria for DISH. In summary, our findings indicate that in DISH, ectopic mineral forms along the anterior aspect of the spine by both heterotopic ossification and dystrophic calcification of fibrocartilaginous tissues. Although both types of ectopic mineralization are captured by current radiographic criteria for DISH, dystrophic calcification may reflect a distinct disease process or an early stage in the pathogenesis of DISH.

Project description:Background Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by the formation of new bone along the anterolateral spinal column at four adjacent vertebral bodies. Purpose To propose and validate criteria for the early phase of DISH by using CT data from two large-scale retrospective cohorts, each with 5-year follow-up. Materials and Methods For this retrospective study, CT data at baseline and follow-up in 1367 patients (cohort I) from 2004 to 2011 were evaluated by two observers to define no DISH, early-stage DISH, and definite DISH on the basis of interval development of consecutive complete or incomplete bone bridges. An independent group of 2267 participants from the COPDGene cohort from 2008 to 2016 was used to validate the early DISH criteria (cohort II). The sensitivity and specificity of early DISH criteria were based on findings in the last CT study as the reference standard by using a nested case-control design. κ Values were calculated between seven readers and with a 3-month interval for one reader. Results Cohort I consisted of 100% men, with a mean age of 60.0 years ± 5.6 (standard deviation) and a mean time between baseline and follow-up CT of 5.0 years ± 1.1. Cohort II consisted of 51% men, with a mean age of 59.9 years ± 8.6 and a mean time between baseline and follow-up CT of 5.4 years ± 0.5. In the derivation cohort, 55 patients comprised the early DISH group. Early DISH was defined as the presence of a spinal segment with a complete bone bridge with an adjacent segment of at least a near-complete bone bridge and another adjacent segment with at least the presence of newly formed bone or when three or more adjacent segments were recorded as showing a near-complete bone bridge. In the validation cohort, sensitivity for early DISH (vs no DISH) was 96% (99 of 103 participants; 95% confidence interval [CI]: 90%, 99%). The corresponding specificity was 83% (1695 of 2034 participants; 95% CI: 82%, 85%). The Fleiss κ for interrater reliability was 0.78 (95% CI: 0.77, 0.78), and the κ for intrarater reliability was 0.89 (95% CI: 0.82, 0.96). Conclusion Early diffuse idiopathic skeletal hyperostosis (DISH) criteria had high sensitivity and specificity for predicting the development of DISH. © RSNA, 2019 Online supplemental material is available for this article.

Project description:ObjectiveTo describe the clinical courses and interventions of symptomatic patients with bilateral vocal fold motion impairment (BVFMI) attributed to diffuse idiopathic skeletal hyperostosis (DISH).Study designRetrospective cohort study.SettingSingle Institution Academic Health Center.MethodsRetrospective chart review of patients ≥18 years old evaluated and treated for symptomatic BVFMI secondary to DISH between February 2021 and March 2023. A literature review was conducted.ResultsA total of 4 cases were identified. All patients were male and had symptomatic BVFMI attributed to cervical spine DISH, as seen on imaging. Symptoms ranged from life-threatening dyspnea to breathy dysphonia in addition to dysphagia. Each patient was offered surgery for DISH. Two patients underwent osteophyte removal at the C5-C6 level with improved vocal fold (VF) mobility, breathing, and voice quality. Two patients elected serial observation as voice, swallow, and airway symptoms were manageable. The literature review showed a male-dominant (100%) presentation with an average of 70 years of age. Hypertension (45%) and diabetes mellitus (36%) were the most common comorbidities. Most patients were treated surgically (55%).ConclusionBoth surgical and conservative interventions may be considered for symptomatic relief and improvement in VF mobility on a patient-to-patient basis. Further study is warranted to investigate the etiology and treatment outcomes in these cases.

Project description:Diffuse idiopathic skeletal hyperostosis (DISH) is often theorized to be an ossification of the anterior longitudinal ligament (ALL). Using computed tomography (CT) imaging and cryomacrotome sectioning, we investigated the spatial relationship between the ALL and newly formed bone in DISH to test this hypothesis. In the current study, four human cadaveric spines diagnosed with DISH using CT imaging were frozen and sectioned using a cryomacrotome. Photographs were obtained of the specimen at 125 µm intervals. Manual segmentations of the ALL on cryomacrotome photographs were projected onto the three-dimensional reconstructed CT scans. The presence and location of newly formed bone were assessed in relationship to the location of the ALL. The ALL could be identified and segmented on the photographs at all levels. The ALL was located at the midline at levels where no new bone had formed. At the locations where new bone had abundantly formed, the ALL was displaced towards to the contralateral side and not replaced by bony tissue. The displacement of the-morphologically normal appearing-ALL away from the newly formed bone implies that newly formed bone in DISH may not originate from the ALL. © 2018 The Authors.
