Objective: To identify risk factors and establish radiographic criteria for distal junctional failure (DJF) in patients with adult spinal deformity (ASD), who underwent fusion surgery stopping at L5. Methods: This retrospective study was undertaken from January 2016 to December 2020. Patients with ASD who underwent fusion surgery (≥5 levels) stopping at L5 were analyzed. DJF was defined as symptomatic adjacent segment pathology at the lumbosacral junction necessitating consideration for revision surgery. Demographic data and radiographic measurements were compared between the DJF and non-DJF groups. Receiver operating characteristic curve analysis was performed to identify the radiographic cutoff value for DJF. Results: Among 76 patients, 16 (21.1%) experienced DJF. DJF was associated with older age, antidepressant/anxiolytic medication, longer level of fusions, and worse preoperative sagittal alignment. Antidepressant/anxiolytic medication (odds ratio, 5.60) and preoperative pelvic incidence (PI)–lumbar lordosis (LL) mismatch>40° (odds ratio, 5.87) were independent risk factors for DJF. Without both factors, the incidence of DJF has been greatly reduced (9.1%). Two radiographic criteria were determined for DJF: last distal junctional angle (DJA)>-5° and Δ last DJA–post DJA>5°. When both criteria were met, the sensitivity and specificity of the DJF were 93.3% and 91.7%, respectively. Conclusion Use of antidepressant/anxiolytic medication and preoperative PI–LL mismatch >40° were independent risk factors for DJF. DJF could be diagnosed using postoperative changes in the DJA. If both criteria were met, DJF could be strongly suggested.

Severe systemic manifestations of adult onset Still's disease (AOSD) are often fatal and occasionally related to hemophagocytic syndrome (HS). We describe the case of a 49-yr-old woman with AOSD presenting with non-remitting high fever, confusion, jaundice, hepatosplenomegaly, serositis, azotemia, pancytopenia, coagulopathy with disseminated intravascular coagulation (DIC), hyperferritinemia, acute acalculous cholecystitis and ileocolitis noted in computed tomographic images. The patient had a history of herpes zoster developed prior to the admission, but there is no history of diarrhea or abdominal pain. Although bone marrow examination was not performed due to hemorrhagic diathesis, we suspected AOSD-associated HS on the basis of clinical course without detectable infectious agents in cultures or serologic studies. Intravenous immunoglobulin, pulse methylprednisolone, oral cyclosporine A (CsA) and ceftriaxone brought about transient improvement of fever and confusion, but the disease progressed. After increasing CsA dose, all previously mentioned abnormalities disappeared rapidly. Accordingly, we believe that DIC and multiple organ dysfunctions might have been the complications of HS but not that of sepsis, and that CsA can be used as a first-line therapy in case of life-threatening situations.

Undifferentiated spondyloarthropathy (USpA) includes the forms that do not meet criteria for the established categories of spondyloarthropathy. The clinical spectrum of USpA is therefore wide and few studies have been published on USpA, especially peripheral arthritis. A total of 107 patients fulfilling the European Spondyloarthropathy Study Group criteria for SpA were studied retrospectively by a chart review and interview by a rheumatologist. Peripheral arthritis, excluding hip and shoulder involvement, occurred in 97 of the 107 patients (91%). Joint involvement tended to be monoarticular or pauciarticular, and most frequently developed in peripheral joints including the knee and ankle. Among the 97 patients with peripheral arthritis, only 37 (35%) had a persistent arthritis. HLA-B27 was detected in 80 patients (78%). Peripheral arthritis was found in the lower extremities regardless of symmetry or asymmetry and tended to run a benign course with only a few patients having persistent arthritis

This study was performed to define the clinical spectrum and disease manifestations of ankylosing spondylitis (AS) in a referral hospital setting. We identified the differences in clinical manifestations according to the sex, the age at onset, the presence of peripheral arthritis and the presence of HLA B27. A total 412 patients (357 males, 55 females) were recruited. Eighty-seven percent were men and 155 out of 412 patients (35%) were juvenile-onset. HLA B27 was detected in 385 patients (93%). Peripheral joint involvement was noted in 287 of total AS cases (juvenile- onset ankylosing spondylitis (JOAS), 82%; adult-onset ankylosing spondylitis (AOAS), 61%), and was more common than those reported in other studies. A greater portion of patients with JOAS had peripheral arthritis and peripheral enthesitis than the patients with AOAS. The patients with peripheral arthritis showed a younger age at onset and an increased tendency of having enthesitis and trauma history. The natural history of Korean AS appears largely similar to those seen in Europe and North America, except a few differences. JOAS was quite common and AS was about nine times more common in men than in women. In addition, the HLA B27 antigen frequency was 93%, which is higher than those reported in other studies.

OBJECTIVE: To assess the health-related quality of life (HRQOL), the correlation among each measurement, and to identify the predictors for HRQOL in Korean patients with ankylosing spondylitis (AS). METHODS: The HRQOL and clinical and laboratory parameters were assessed by Short Form Health Survey-36 (SF-36), EuroQol5 Dimensions (EQ-5D), time trade off (TTO), standard gamble (SG), Centers for Epidemiologic StudiesDepression (CES-D), social support, self-efficacy scale, Bath Ankylosing Spondylitis Functional Index (BASFI), Schober test, occiput to wall test, ESR, and CRP from 90 patients with AS. RESULTS: 78 patients (86.7%) were men with a mean (+/-SD) age of 28.4 (+/-7.9) years. The mean years of disease onset was 10.44 (+/-6.95). The mean scores of SF-36 global, mental component summary (MCS) and physical component summary (PCS) were 53.4 (+/-21.2), 61.8 (+/-26.3), and 51.7 (+/-24.4), respectively. The mean EQ-5D utility and visual analog scale (VAS) score were 0.63 (+/-0.2) and 57.1 (+/-18.6). The mean scores of the TTO and SG were 0.46 (+/-0.6) and 0.46 (+/-0.6). The scores of the SF-36 and EQ-5D in AS patients were lower than those in healthy control. The mean scores of CES-D, self-efficacy scale, social support and social network were 10.5 (+/-6.8), 65.3 (+/-14.6), 2.46 (+/-0.22), and 2.33 (+/-0.47), respectively. The mean score of BASFI was 2.48 (+/-2.13). The BASFI total score was negatively correlated with the scores of SF-36, MCS, PCS, EQ-5D utility and VAS score, social network, and self-efficacy scale, and positively correlated with CES-D. In multivariate models, the predicting variables of SF-36 global and PCS were BASFI and self-efficacy scale and the predicting variables of SF-36 MCS were BASFI, social support, and self-efficacy scale. CONCLUSION: In this study, we observed that HRQOL in Korean patients with ankylosing spondylitis is decreased compare to healthy control. And the efforts to improve HRQOL should be designed to improve the self-efficacy and social support in addition to active treatment to prevent functional disability.
