RESUMO
INTRODUCTION: Hemophagocytic syndrome (HPS) is a rare but potentially fatal complication of viral infections. Epstein-Barr virus (EBV) and cytomegalovirus (CMV) often infect patients receiving TNF-alpha inhibitors (TNF-α inhibitors). While EBV and CMV are well established infections for the development of infectious mononucleosis, coinfection with EBV and CMV is common among immunosuppressed patients and can result in a fatal course. In addition, such viral infections can cause HPS. To the best of our knowledge, we present here the first report of HPS induced by EBV and CMV coinfection during anti-TNFα inhibitor use. CASE REPORT: A 23-year-old man hospitalized with fever, elevated liver enzymes, lymphadenopathy, and hepatosplenomegaly was diagnosed with HPS associated with EBV and CMV coinfection while using adalimumab. No clinical improvement was observed after discontinuation of adalimumab. HPS complicated by EBV and CMV coinfection was finally diagnosed, and immediate administration of ganciclovir and prednisone was considered to have prevented a lethal clinical outcome. CONCLUSION: For cases showing unexplained fever, elevated liver enzymes, and lymphadenopathy while using anti-TNFα inhibitors, screening for EBV and CMV coinfection should be encouraged. In addition, HPS should be considered in patients with EBV and/or CMV infection receiving anti-TNFα inhibitors to facilitate early definitive therapy.

The RDT population, initially at 215 patients, exceeded 300,000 in 2011, with a total of 329,609 patients at the end of December 2016. In our Institute, the number of patients with destructive spondylosis is increasing with the increase in the number of dialysis patients in Japan. We had 14 Cases in the 1990s, and then 82 cases in the 2000s and have already had 131 cases in the 2010s. The purpose of this study was to investigate the incidence of dialysis-related amyloidosis (DRA) such as destructive spondyloarthropathy (DSA), dialysis amyloid arthropathy (DAA), and carpal tunnel syndrome (CTS). In addition, another purpose was to examine the risk factors of the DRA. DAA made its own assessment on radiographs based on stage. Survey items were patient's basic data, laboratory data and X-ray view. Patient's basic data included such as sex, age, height, and weight and RDT-related factors such as kidney disease that led to RDT, age at start of RDT, RDT history, medical history (past and present), and history of surgery. The frequency of DRA was examined by medical history and radiological examination in 199 dialysis patients who obtained informed consent. The patients were divided into two groups according to the presence or absence of DRA, and risk factors of DRA were investigated from the medical history, basic data of patients, and blood tests. Of the 199 patients on regular dialysis therapy, 41 (20.6%) showed DRA. Based on the X-ray images, 21 patients (10.6%) showed DSA, while 22 patients (11.1%) showed DAA. Sixteen patients (8.0%) had CTS, determined through a history of surgery. Regarding overlap of conditions, 14 had both DSA and DAA, 3 had both DSA and CTS, and 2 had both DAA and CTS. There were statistically significant differences between the two groups in the cause of disease in Chronic glomerulonephritis and Diabetic Nephropathy, age at the start of RDT, period of RDT, body weight, blood platelet count, and blood Ca level. When multivariate analysis was performed on these items, statistical differences were recognized only during the dialysis period. In conclusion, long dialysis period was a risk factor for DRA.

Surgical antibiotic prophylaxis (SAP) is recommended for the prevention of surgical site infections. However, there is a concern about adverse effects of SAP, such as antibiotic-associated diarrhea (AAD). To prevent AAD, administration of probiotics has been investigated. Although recent advances in next-generation sequencing makes it possible to analyze the gut microbiome, the effect of probiotics on the gut microbiome in the patients with SAP remains unknown. To test a hypothesis that SAP influences the gut microbiome and probiotics prevent the influence, a randomized controlled study was conducted with patients who underwent spinal surgery at Nagasaki University Hospital. After obtaining informed consent, the patients were automatically classified into the non-probiotics group and the probiotics group. In the probiotics group, the patients took 1 g of Enterococcus faecium 129 BIO 3B-R, 3 times a day on postoperative days (PODs) 1-5. The feces of all patients were sampled before administration of SAP and on PODs 5 and 10. We compared alpha and beta diversity and differential abundance analysis of the gut microbiome before and after SAP. During the study period, a total of 33 patients were evaluated, comprising 17 patients in the non-probiotics group and 16 in the probiotics group. There was no significant difference between the groups regarding patient characteristics. In alpha and beta diversity, there were no significant differences among all combinations. In differential abundance analysis at operational taxonomic unit level, Streptococcus gallolyticus and Roseburia were significantly increased in the non-probiotics group and significantly decreased in the probiotics group.

BACKGROUND: The optimal treatment of osteoporosis after reconstruction surgery for osteoporotic vertebral fractures (OVF) remains unclear. In this multicentre retrospective study, we investigated the effects of typically used agents for osteoporosis, namely, bisphosphonates (BP) and teriparatide (TP), on surgical results in patients with osteoporotic vertebral fractures. METHODS: Retrospectively registered data were collected from 27 universities and affiliated hospitals in Japan. We compared the effects of BP vs TP on postoperative mechanical complication rates, implant-related reoperation rates, and clinical outcomes in patients who underwent posterior instrumented fusion for OVF. Data were analysed according to whether the osteoporosis was primary or glucocorticoid-induced. RESULTS: A total of 159 patients who underwent posterior instrumented fusion for OVF were included. The overall mechanical complication rate was significantly lower in the TP group than in the BP group (BP vs TP: 73.1% vs 58.2%, p = 0.045). The screw backout rate was significantly lower and the rates of new vertebral fractures and pseudoarthrosis tended to be lower in the TP group than in the BP group. However, there were no significant differences in lumbar functional scores and visual analogue scale pain scores or in implant-related reoperation rates between the two groups. The incidence of pseudoarthrosis was significantly higher in patients with glucocorticoid-induced osteoporosis (GIOP) than in those with primary osteoporosis; however, the pseudoarthrosis rate was reduced by using TP. The use of TP also tended to reduce the overall mechanical complication rate in both primary osteoporosis and GIOP. CONCLUSIONS: The overall mechanical complication rate was lower in patients who received TP than in those who received a BP postoperatively, regardless of type of osteoporosis. The incidence of pseudoarthrosis was significantly higher in patients with GIOP, but the use of TP reduced the rate of pseudoarthrosis in GIOP patients. The use of TP was effective to reduce postoperative complications for OVF patients treated with posterior fusion.

BACKGROUND: Vertebroplasty with posterior spinal fusion (VP + PSF) is one of the most widely accepted surgical techniques for treating osteoporotic vertebral collapse (OVC). Nevertheless, the effect of the extent of fusion on surgical outcomes remains to be established. This study aimed to evaluate the surgical outcomes of short- versus long-segment VP + PSF for OVC with neurological impairment in thoracolumbar spine. METHODS: We retrospectively collected data from 133 patients (median age, 77 years; 42 men and 91 women) from 27 university hospitals and their affiliated hospitals. We divided patients into two groups: a short-segment fusion group (S group) with 2- or 3-segment fusion (87 patients) and a long-segment fusion group (L group) with 4- through 6-segment fusion (46 patients). Surgical invasion, clinical outcomes, local kyphosis angle (LKA), and complications were evaluated. RESULTS: No significant differences between the two groups were observed in terms of neurological recovery, pain scale scores, and complications. Surgical time was shorter and blood loss was less in the S group, whereas LKA at the final follow-up and correction loss were superior in the L group. CONCLUSION: Although less invasiveness and validity of pain and neurological relief are secured by short-segment VP + PSF, surgeons should be cautious regarding correction loss.

BACKGROUND: To date, there have been little published data on surgical outcomes for patients with PD with thoracolumbar OVF. We conducted a retrospective multicenter study of registry data to investigate the outcomes of fusion surgery for patients with Parkinson's disease (PD) with osteoporotic vertebral fracture (OVF) in the thoracolumbar junction. METHODS: Retrospectively registered data were collected from 27 universities and their affiliated hospitals in Japan. In total, 26 patients with PD (mean age, 76 years; 3 men and 23 women) with thoracolumbar OVF who underwent spinal fusion with a minimum of 2 years of follow-up were included (PD group). Surgical invasion, perioperative complications, radiographic sagittal alignment, mechanical failure (MF) related to instrumentation, and clinical outcomes were evaluated. A control group of 296 non-PD patients (non-PD group) matched for age, sex, distribution of surgical procedures, number of fused segments, and follow-up period were used for comparison. RESULTS: The PD group showed higher rates of perioperative complications (p < 0.01) and frequency of delirium than the non-PD group (p < 0.01). There were no significant differences in the degree of kyphosis correction, frequency of MF, visual analog scale of the symptoms, and improvement according to the Japanese Orthopaedic Association scoring system between the two groups. However, the PD group showed a higher proportion of non-ambulators and dependent ambulators with walkers at the final follow-up (p < 0.01). CONCLUSIONS: A similar surgical strategy can be applicable to patients with PD with OVF in the thoracolumbar junction. However, physicians should pay extra attention to intensive perioperative care to prevent various adverse events and implement a rehabilitation regimen to regain walking ability.

BACKGROUND: There have been few reports on the incidence and risk factors of the complications after spinal fixation surgery for osteoporotic vertebral collapse (OVC) with neurological deficits. This study aimed to identify the incidence and risk factors of the complications after OVC surgery. METHODS: In this retrospective multicenter study, a total of 403 patients (314 women and 89 men; mean age 73.8 years) who underwent spinal fixation surgery for OVC with neurological deficits between 2005 and 2014 were enrolled. Data on patient demographics were collected, including age, sex, body mass index, smoking, steroid use, medical comorbidities, and surgical procedures. All postoperative complications that occurred within 6 weeks were recorded. Patients were classified into two groups, namely, complication group and no complication group, and risk factors for postoperative complications were investigated by univariate and multivariate analyses. RESULTS: Postoperative complications occurred in 57 patients (14.1%), and the most common complication was delirium (5.7%). In the univariate analysis, the complication group was found to be older (p = 0.039) and predominantly male (p = 0.049), with higher occurrence rate of liver disease (p = 0.001) and Parkinson's disease (p = 0.039) compared with the no-complication group. In the multivariate analysis, the significant independent risk factors were age (p = 0.021; odds ratio [OR] 1.051, 95% confidence interval [CI] 1.007-1.097), liver disease (p < 0.001; OR 8.993, 95% CI 2.882-28.065), and Parkinson's disease (p = 0.009; OR 3.636, 95% CI 1.378-9.599). CONCLUSIONS: Complications after spinal fixation surgery for OVC with neurological deficits occurred in 14.1%. Age, liver disease, and Parkinson's disease were demonstrated to be independent risk factors for postoperative complications.

BACKGROUND: A consensus on the optimal surgical procedure for thoracolumbar OVF has yet to be reached due to the previous relatively small number of case series. The study was conducted to investigate surgical outcomes for osteoporotic vertebral fracture (OVF) in the thoracolumbar spine. METHODS: In total, 315 OVF patients (mean age, 74 years; 68 men and 247 women) with neurological symptoms who underwent spinal fusion with a minimum 2-year follow-up were included. The patients were divided into 5 groups by procedure: anterior spinal fusion alone (ASF group, n = 19), anterior/posterior combined fusion (APSF group, n = 27), posterior spinal fusion alone (PSF group, n = 40), PSF with 3-column osteotomy (3CO group, n = 92), and PSF with vertebroplasty (VP + PSF group, n = 137). RESULTS: Mean operation time was longer in the APSF group (p < 0.05), and intraoperative blood loss was lower in the VP + PSF group (p < 0.05). The amount of local kyphosis correction was greater in the APSF and 3CO groups (p < 0.05). Clinical outcomes were approximately equivalent among all groups. CONCLUSION: All 5 procedures resulted in acceptable neurological outcomes and functional improvement in walking ability. Moreover, they were similar with regard to complication rates, prevalence of mechanical failure related to the instrumentation, and subsequent vertebral fracture. Individual surgical techniques can be adapted to suit patient condition or severity of OVF.

Computed tomography (CT) attenuation values of cervical spine were evaluated in vivo using a clinically relevant group. To compare CT attenuation values between cervical pedicle screw (CPS), lateral mass screw (LMS), and paravertebral foramen screw (PVFS) trajectories. CPS and LMS are commonly used for posterior fixation of the cervical spine. The PVFS method has been reported as a new method. CT attenuation values along the screw trajectory are reportedly associated with screw stability. We identified 45 patients who had undergone whole-body CT for trauma with no injury to the cervical spine. Regions of interest (ROIs) were designated along the trajectories that would be used for CPS, LMS, and PVFS through vertebral pedicles and lateral masses of the C3-C6 vertebrae. CT attenuation values of each ROI were measured and compared between each screw trajectories at each cervical vertebral level. Participants were divided into Group I (age, 20-39 years; n = 12), Group II (age, 40-59 years; n = 17), and Group III (age, 60-79 years; n = 16). CT attenuation values of ROIs were compared between each age group. PVFS trajectories showed higher CT attenuation values than LMS trajectories at every vertebral level and also higher values than CPS trajectories at C5 and C6 levels. CT attenuation values at C3 were lower than those at C4 in the LMS trajectory and lower than those at C5 and C6 in the PVFS trajectory. CT attenuation values were lower in the elder group (>60 years old) than in the other 2 groups for all screw trajectories. CT attenuation values suggested that the PVFS technique may be useful for posterior fixation of the cervical spine in elder patients who require more secure fixation.

The COVID-19 vaccine will be safe and effective in solid organ transplant recipients (SOTs). However, the blunted antibody responses were also of concern. Few studies have reported prolonged serologic follow-up after 2 doses of BNT162b2 vaccine in SOTs. We performed a single-center, prospective observational study of 78 SOTs who received 2 doses of BNT162b2 vaccine. We identified the trajectory of antibody titers after vaccination among SOTs with or without mycophenolate mofetil (MMF) or withdrawn from MMF. We found low seroconversion rates (29/42: 69%) and low antibody titers in SOTs treated with MMF. An inverse linear relationship between neutralizing antibody titers and MMF concentration was confirmed in restricted cubic spline plots (P for effect < .01, P for nonlinearityâ¯=â¯.08). For the trajectory of antibody responses, seroconversion and improved antibody titers were observed after withdrawal from MMF in SOTs who showed seronegative or low antibody titers at the first visit after 2 doses of vaccine (P for effect < .01, P for nonlinearity < .05, and P for interaction < .01). We identified increased B-cell counts after withdrawal from MMF (P < .01). The recovery of antibody responses was seen in SOTs withdrawn from MMF. The trajectories of antibody responses were modified by MMF administration.

A retrospective multicenter study. Body mass index (BMI) is recognized as an important determinant of osteoporosis and spinal postoperative outcomes; however, the specific impact of BMI on surgery for osteoporotic vertebral fractures (OVFs) remains inconclusive. This retrospective multicenter study investigated the impact of BMI on clinical outcomes following fusion surgery for OVFs. 237 OVF patients (mean age, 74.3 years; 48 men and 189 women) with neurological symptoms who underwent spinal fusion were included in this study. Patients were grouped by World Health Organization BMI categories: low BMI (<18.5 kg/m2), normal BMI (≥18.5 andâ <25 kg/m2), and high BMI (≥25 kg/m2). Patients' backgrounds, surgical method, radiological findings, pain measurements, activities of daily living (ADL), and postoperative complications were compared after a mean follow-up period of 4 years. As results, the proportion of patients able to walk independently was significantly smaller in the low BMI group (75.0%) compared with the normal BMI group (89.9%; Pâ =â .01) and the high BMI group (94.3%; Pâ =â .04). Improvement in the visual analogue scale for leg pain was significantly less in the low BMI group than the high BMI group (26.7 vs 42.8 mm; Pâ =â .046). Radiological evaluation, the Frankel classification, and postoperative complications were not significantly different among all 3 groups. Improvement of pain intensity and ADL in the high BMI group was equivalent or non-significantly better for some outcome measures compared with the normal BMI group. Leg pain and independent walking ability after fusion surgery for patients with OVFs improved less in the low versus the high BMI group. Surgeons may want to carefully evaluate at risk low BMI patients before fusion surgery for OVF because poor clinical results may occur.

BACKGROUND: Feeding device replacement is often required for long-term maintenance after initial percutaneous endoscopic gastrostomy or jejunostomy placement. Although there are several case reports on serious complications of gastrostomy device replacement, there are few reports of an overall analysis of the complications associated with feeding device replacement. OBJECTIVE: To evaluate the frequency and variety of complications of transcutaneous replacement of feeding devices. DESIGN: A retrospective study. SETTING: Single center: Nishimino Kosei Hospital. PATIENTS: This study involved 363 consecutive patients undergoing a total of 1265 percutaneous gastrostomy or jejunostomy device replacements from March 2000 to September 2010. INTERVENTION: A new replacement device was inserted through the ostomy tract by using an obturator after traction removal of the previous device. Endoscopic treatments were performed in the cases of fistula disruption or hemorrhage. MAIN OUTCOME MEASUREMENTS: Complications and their outcomes. RESULTS: Gastrostomy and jejunostomy devices were replaced 1126 and 139 times, respectively. There were 16 complications (1.3% of total replacements) consisting of 10 cases of fistula disruption caused by misplacement of replacement devices into the peritoneal cavity, 4 cases of hemorrhage, and 1 case each of colocutaneous fistula and device breakage. Anticoagulation or antiplatelet medications were continued in all 4 hemorrhage cases but in only 27 of 347 (7.7%) complication-free cases (P < .0001). There were no replacement-related adverse events that required surgical repair. LIMITATIONS: A single center, retrospective analysis. CONCLUSION: Fistula disruption and hemorrhage were the most common complications associated with device replacement. In patients on anticoagulants, caution is necessary to avoid hemorrhage after replacement. It is also important to verify that the replaced device is located in the GI tract lumen before feeding.

BACKGROUND: Ischemic colitis with inferior mesenteric arteriovenous malformation (AVM) is a rare disease. Although a few reports have been published, no report has described the natural history of idiopathic mesenteric AVM. CASE SUMMARY: A 50-year-old male was admitted to our hospital due to abdominal pain that had persisted for 3 mo and bloody diarrhea. He had no history of trauma or abdominal surgery. He had undergone two colonoscopies 6 mo and 2 years ago, and they showed only a polyp. He was diagnosed with ischemic colitis with inferior mesenteric AVM following contrast-enhanced abdominal computed tomography (CT) and underwent rectal low anterior resection. He has not had a recurrence of symptoms for 3 years. His history showed that he had undergone non-enhanced abdominal CT 2, 5, and 8 years ago when he had attacks of urinary stones. Retrospectively, dilation of blood vessels around the rectosigmoid colon could have been detected 5 years ago, and these findings gradually became more evident. CONCLUSION: This is the first report of the natural history of inferior mesenteric AVM.
RESUMO
BACKGROUND: Upper gastrointestinal (GI) hemorrhage after percutaneous endoscopic gastrostomy (PEG) is sometimes reported as one of the serious complications. Our purpose was to clarify the cause of upper GI hemorrhage after PEG. PATIENTS AND METHODS: We retrospectively investigated the causes of upper GI hemorrhage among a total of 416 patients out of 426 consecutive patients who underwent PEG in our institution, excluding 10 patients who showed upper GI tumors on PEG placement. RESULTS: Among 17 patients who developed upper GI hemorrhage after PEG, three and four patients showed PEG tube placement and replacement-related hemorrhage, respectively; these lesions were vascular or mucosal tears around the gastrostomy site. Ten patients experienced 12 episodes of upper GI hemorrhage during PEG tube feeding. The lesions showing bleeding were caused by reflux esophagitis (five patients), gastric ulcer (two patients), gastric erosion due to mucosal inclusion in the side hole of the internal bolster (two patients), and duodenal diverticular hemorrhage (one patient). Anticoagulants were administered in six patients, including four patients with replacement-related hemorrhage and one patient each with reflux esophagitis and gastric ulcer. CONCLUSIONS: Reflux esophagitis was the most frequent reason for upper GI hemorrhage after PEG. The interruption of anticoagulants should be considered for the prevention of hemorrhage on the placement as well as replacement of a gastrostomy tube.

A 72-year-old woman received combination therapy with peginterferon alpha and ribavirin for treatment of chronic hepatitis C. Approximately 40 weeks after starting treatment, she developed an eruption in the left inner canthus and sarcoidosis was diagnosed after biopsy of the eruption. Combination therapy was discontinued, and further detailed examinations revealed bilateral hilar lymphadenopathy, uveitis, and complete atrioventricular block. A permanent cardiac pacemaker was implanted, and her sarcoidosis improved upon administration of corticosteroids.

INTRODUCTION: Osteoporotic vertebral fracture (OVF) is the most common osteoporotic fracture, and some patients require surgical intervention to improve their impaired activities of daily living with neurological deficits. However, many previous reports have focused on OVF around the thoracolumbar junction, and the surgical outcomes of lumbar OVF have not been thoroughly discussed. We aimed to investigate the surgical outcomes for lumbar OVF with a neurological deficit. METHODS: Patients who underwent fusion surgery for thoracolumbar OVF with a neurological deficit were enrolled at 28 institutions. Clinical information, comorbidities, perioperative complications, Japanese Orthopaedic Association scores, visual analog scale scores, and radiographic parameters were compared between patients with lower lumbar fracture (L3-5) and those with thoracolumbar junction fracture (T10-L2). Each patient with lower lumbar fracture (L group) was matched with to patients with thoracolumbar junction fracture (T group). RESULTS: A total 403 patients (89 males and 314 females, mean age: 73.8 ± 7.8 years, mean follow-up: 3.9 ± 1.7 years) were included in this study. Lower lumbar OVF was frequently found in patients with lower bone mineral density. After matching, mechanical failure was more frequent in the L group (L group: 64%, T group: 39%; p < 0.001). There was no difference between groups in the clinical and radiographical outcomes, although the rates of complication and revision surgery were still high in both groups. CONCLUSIONS: The surgical intervention for OVF is effective in patients with myelopathy or radiculopathy regardless of the surgical level, although further study is required to improve clinical and radiographical outcomes. LEVEL OF EVIDENCE: Level III.
RESUMO
BACKGROUND: Aspiration is one of the major complications after percutaneous endoscopic gastrostomy (PEG). The administration of semi-solid nutrients by means of gastrostomy tube has recently been reported to be effective in preventing aspiration pneumonia. The effects of semi-solid nutrients on gastroesophageal reflux, intragastric distribution, and gastric emptying were evaluated. METHODS: Semi-solid nutrients were prepared by liquid nutrients mixed with agar at the concentration of 0.5%. The distribution of the administered radiolabeled liquid and semi-solid nutrients was monitored by a scintillation camera for 15 post-PEG patients. The percentage of esophageal reflux, the distribution of the proximal and distal stomach, and the gastric emptying time were evaluated. RESULTS: The percentage of gastroesophageal reflux was significantly decreased in semi-solid nutrients (0.82 +/- 1.27%) compared with liquid nutrients (3.75 +/- 4.25%), whereas the gastric emptying time was not different. The distribution of semi-solid nutrients was not different from liquid nutrients in the early phase, whereas higher retention of liquid nutrients in the proximal stomach was observed in the late phase. CONCLUSIONS: Gastroesophageal reflux was significantly inhibited by semi-solid nutrients. One of the mechanisms of the inhibition is considered to be an improvement in the transition from the proximal to distal stomach in semi-solid nutrients.

INTRODUCTION: Approximately 3% of osteoporotic vertebral fractures develop osteoporotic vertebral collapse (OVC) with neurological deficits, and such patients are recommended to be treated surgically. However, a proximal junctional fracture (PJFr) following surgery for OVC can be a serious concern. Therefore, the aim of this study is to identify the incidence and risk factors of PJFr following fusion surgery for OVC. METHODS: This study retrospectively analyzed registry data collected from facilities belonging to the Japan Association of Spine Surgeons with Ambition (JASA) in 2016. We retrospectively analyzed 403 patients who suffered neurological deficits due to OVC below T10 and underwent corrective surgery; only those followed up forã≥2 years were included. Potential risk factors related to the PJFr and their cut-off values were calculated using multivariate logistic regression analysis and receiver operating characteristic (ROC) analysis. RESULTS: Sixty-three patients (15.6%) suffered PJFr during the follow-up (mean 45.7 months). In multivariate analysis, the grade of osteoporosis (grade 2, 3: adjusted odds ratio (aOR) 2.92; p=0.001) and lower instrumented vertebra (LIV) level (sacrum: aOR 6.75; p=0.003) were independent factors. ROC analysis demonstrated that lumbar bone mineral density (BMD) was a predictive factor (area under curve: 0.72, p=0.035) with optimal cut-off value of 0.61 g/cm2 (sensitivity, 76.5%; specificity, 58.3%), but that of the hip was not (p=0.228). CONCLUSIONS: PJFr was found in 16% cases within 4 years after surgery; independent risk factors were severe osteoporosis and extended fusion to the sacrum. The lumbar BMD with cut-off value 0.61 g/cm2 may potentially predict PJFr. Our findings can help surgeons select perioperative adjuvant therapy, as well as a surgical strategy to prevent PJFr following surgery.
RESUMO
INTRODUCTION: The prevalence of patients with osteoporosis continues to increase in aging societies, including Japan. The first choice for managing osteoporotic vertebral compression fracture (OVF) is conservative treatment. Failure in conservative treatment for OVF may lead to non-union or vertebral collapse, resulting in neurological deficit and subsequently requiring surgical intervention. This multicenter nationwide study in Japan was conducted to comprehensively understand the outcomes of surgical treatments for OVF non-union. METHODS: This multicenter, retrospective study included 403 patients (89 males, 314 females, mean age 73.8 ± 7.8 years, mean follow-up 3.9 ± 1.7 years) with neurological deficit due to vertebral collapse or non-union after OVF at T10-L5 who underwent fusion surgery with a minimum 1-year follow-up. Radiological and clinical outcomes at baseline and at the final follow-up (FU) were evaluated. RESULTS: OVF was present at a thoracolumbar junction such as T12 (124 patients) and L1 (117 patients). A majority of OVF occurred after a minor trauma, such as falling down (55.3%) or lifting objects (8.4%). Short segment fusion, including affected vertebra, was conducted (mean 4.0 ± 2.0 vertebrae) with 256.8 minutes of surgery and 676.1 g of blood loss. A posterior approach was employed in 86.6% of the patients, followed by a combined anterior and posterior (8.7%), and an anterior (4.7%) approach. Perioperative complications and implant failures were observed in 18.1% and 41.2%, respectively. VAS scores of low back pain (74.7 to 30.8 mm) and leg pain (56.8 to 20.7 mm) improved significantly at FU. Preoperatively, 52.6% of the patients were unable to walk and the rate of non-ambulatory patients decreased to 7.5% at FU. CONCLUSIONS: This study demonstrated that substantial improvement in activity of daily living (ADL) was achieved by fusion surgery. Although there was a considerable rate of complications, fusion surgery is beneficial for elderly OVF patients with non-union.
RESUMO
STUDY DESIGN: Prospective imaging study. OBJECTIVE: To clarify the frequency of positional vertebral artery (VA) occlusion using duplex ultrasonography in patients with rheumatoid arthritis (RA). SUMMARY OF BACKGROUND DATA: Some patients with upper cervical RA develop thromboembolic stroke related to positional and transient VA occlusions; however, whether RA patients have positional VA occlusion without neurological symptoms is unclear. METHODS: Outpatients with RA were enrolled. Clinical data were collected, and radiograph examinations were performed to measure the anterior atlantodental interval (AADI), the posterior atlantodental interval (PADI), and the Ranawat method. Patients underwent duplex ultrasonography during rotation to the contralateral side of the examination side, flexion, and extension of their neck. If positional VA occlusion was detected, CT angiography was conducted in the neutral position and in the same position that showed VA occlusion on duplex ultrasonography. Clinical and radiological data were compared between the VA occlusion (VAO) group and the non-VAO group. Sensitivity-specificity curve analyses were performed to clarify optimal threshold values of AADI, PADI, and the Ranawat method for predicting positional VA occlusion. RESULTS: Of the 132 RA patients, dynamic duplex ultrasonography showed positional VA occlusion in eight (6%) patients. Patients in the VAO group had a greater AADI (median, 7.4 vs. 2.3âmm; Pâ<â0.001), a shorter PADI (median, 13.7 vs. 19.6âmm; Pâ=â0.002), and a lower Ranawat value (median, 13.7 vs. 16.8âmm; Pâ=â0.006) than those in the non-VAO group. Cut-off values of AADI, PADI, and the Ranawat method for predicting positional VA occlusion were 6.5, 14.0, and 15.5âmm, respectively. CONCLUSION: A subset of RA patients developed positional VA occlusion associated with cervical spine involvement.
