    Background: Fixed severe hyperkyphotic deformities spread over more than five vertebral levels represent a therapeutic challenge, especially when the deformity apex is located at the thoraco-lumbar junction, thus requiring a huge amount of correction. The aim of this article is to describe an innovative all-posterior corrective technique based on multilevel non-contiguous thoracic pedicle subtraction ostoeotomy (PSO). Materials and methods: A retrospective review of three patients with fixed severe thoracic hyperkyphosis (a deformity angle of over 70°) with a thoraco-lumbar apex (between T11 and L1) treated by simultaneous two-level thoracic PSO and thoraco-lumbar posterior fusion was performed. Radiographic and clinical records were evaluated pre-operatively, post-operatively and at last follow-up (after a minimum of 2 years). Each variable was presented as mean ± SD (standard deviation). Statistical analyses were performed using paired t-tests (P value < 0.05 was considered significant). Results: The mean local deformity angle decreased by 75% (from 81.3° ± 2.1° to 20.7° ± 1.4°, p < 0.001), the post-operative thoracic kyphosis decreased by 46% (from 61.4° ± 2.4° to 33.2° ± 0.9°, p < 0.001) and the sagittal vertical axis decreased by 73% (from 14.7 cm ± 0.8 cm to 3.9 cm ± 0.3 cm, p < 0.001). No differences were observed in the radiological results between post-operative values and those at the final follow-up. The average Oswestry Disability Index (ODI) score reduced from 65.7 ± 1.8 pre-operatively to 17.3 ± 1.7 at last follow-up (p < 0.001). No neurological, mechanical nor infective complication occurred. Conclusions: The presented technique, although technically demanding, proved to be a safe and effective alternative for the management of fixed severe thoraco-lumbar junction hyperkyphotic deformities.

    Optimizing Patient Care: A Systematic Review of Multidisciplinary Approaches for SLE Management

    Get PDF
    Systemic lupus erythematosus (SLE) is characterized by multisystemic clinical manifestations ranging from a relatively mild involvement to potentially life-threatening complications. Due to this complexity, a multidisciplinary (MD) approach is the best strategy for optimizing patients' care. The main aim of this systematic literature review (SLR) was to scrutinize the published data regarding the MD approach for the management of SLE patients. The secondary objective was to evaluate the outcomes of the MD approach in SLE patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used. We performed an SLR to retrieve articles available in English or Italian listed in PubMed, Embase, Cinahl, and Cochrane Library concerning the MD approach used in observational studies and clinical trials. Four independent reviewers performed the study selection and data collection. Of 5451 abstracts evaluated, 19 studies were included in the SLR. The MD approach was most frequently described in the context of SLE pregnancy, reported in 10 papers. MD teams were composed of a rheumatologist, except for one cohort study; a gynecologist; a psychologist; a nurse; and other health professionals. MD approaches had a positive impact on pregnancy-related complications and disease flares and improved SLE psychological impact. Although international recommendations advise an MD approach for managing SLE, our review highlighted the paucity of data supporting this strategy, with most of the available evidence on the management of SLE during pregnancy

    Surgical treatment of severe adolescent idiopathic scoliosis through one-stage posterior-only approach: A systematic review and meta-analysis

    Get PDF
    : The aim of this meta-analysis was to analyze the results of one-stage all-posterior spinal fusion for severe adolescent idiopathic scoliosis (AIS). A systematic search of articles about one-stage posterior spinal fusion for severe AIS was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data about population, pre-and postoperative radiographical data, surgical procedure details, and complications were extracted. Meta-analyses were performed when possible. Fourteen studies (640 patients) were included. The mean Cobb angle of the major curve varied from 80.0 ± 7.3 to 110.8 ± 12.1. The meta analysis showed a comprehensive coronal correction rate of the major curve of 58.6%, a comprehensive operative time of 274.5 min, and a comprehensive estimated intraoperative blood loss of 866.5 mL (95% confidence interval: 659.3-1073.6, I 2 ≈ 0%). A total of 48 complications (5.4%) were reported. Overall, the meta-analysis showed a major complication rate of 4%. In seven cases, revision surgery was needed. Posterior-only approach is effective enough to correct severe curves and can spare the patient possible adverse events due to anterior approach. However, when choosing this approach for severe AIS, screw density needs to be high and posterior column osteotomies may need to be planned to mobilize the spine and maximize correction

    Sharing Circulating Micro-RNAs between Osteoporosis and Sarcopenia: A Systematic Review

    Background: Osteosarcopenia, a combination of osteopenia/osteoporosis and sarcopenia,is a common condition among older adults. While numerous studies and meta-analyses have beenconducted on osteoporosis biomarkers, biomarker utility in osteosarcopenia still lacks evidence. Here,we carried out a systematic review to explore and analyze the potential clinical of circulating microR-NAs (miRs) shared between osteoporosis/osteopenia and sarcopenia. Methods: We performed asystematic review on PubMed, Scopus, and Embase for differentially expressed miRs (p-value < 0.05)in (i) osteoporosis and (ii) sarcopenia. Following screening for title and abstract and deduplication,83 studies on osteoporosis and 11 on sarcopenia were identified for full-text screening. Full-textscreening identified 54 studies on osteoporosis, 4 on sarcopenia, and 1 on both osteoporosis andsarcopenia. Results: A total of 69 miRs were identified for osteoporosis and 14 for sarcopenia. Therewere 9 shared miRs, with evidence of dysregulation (up- or down-regulation), in both osteoporo-sis and sarcopenia: miR-23a-3p, miR-29a, miR-93, miR-133a and b, miR-155, miR-206, miR-208,miR-222, and miR-328, with functions and targets implicated in the pathogenesis of osteosarcopenia.However, there was little agreement in the results across studies and insufficient data for miRsin sarcopenia, and only three miRs, miR-155, miR-206, and miR-328, showed the same directionof dysregulation (down-regulation) in both osteoporosis and sarcopenia. Additionally, for mostidentified miRs there has been no replication by more than one study, and this is particularly true forall miRs analyzed in sarcopenia. The study quality was typically rated intermediate/high risk of bias.The large heterogeneity of the studies made it impossible to perform a meta-analysis. Conclusions:The findings of this review are particularly novel, as miRs have not yet been explored in the context ofosteosarcopenia. The dysregulation of miRs identified in this review may provide important clues tobetter understand the pathogenesis of osteosarcopenia, while also laying the foundations for furtherstudies to lead to effective screening, monitoring, or treatment strategies (PDF) Sharing Circulating Micro-RNAs between Osteoporosis and Sarcopenia: A Systematic Review.

    The association of other autoimmune diseases in patients with Graves’ disease (with or without ophthalmopathy): Review of the literature and report of a large series

    Get PDF
    Graves’ disease (GD) and autoimmune thyroiditis (AT) are the two main clinical presentations of AITD, and their clinical hallmarks are thyrotoxicosis and hypothyroidism, respectively. GD, and AT, can be associated with other organ specific, or systemic autoimmune diseases in the same patient. However discordant results have been reported in the literature about the possible associations. Here, we review the association of GD and other autoimmune syndromes. Furthermore, we report the results of our prospective study that investigated the prevalence of other autoimmune disorders in 3209 GD patients (984 with Graves’ ophthalmopathy), with respect to 1069 healthy controls, or 1069 patients with AT, or 1069 with multinodular goiter (matched by age, gender, coming from the same area, with a similar iodine intake). On the whole, 16.7% of GD patients had another associated autoimmune disease; and the most frequently observed were: vitiligo (2.6%), chronic autoimmune gastritis (2.4%), rheumatoid arthritis (1.9%), polymyalgia rheumatica (1.3%), multiple sclerosis (0.3%), celiac disease (1.1%), diabetes (type 1) (0.9%), systemic lupus erythematosus and sarcoidosis (<0.1%), Sjogren disease (0.8%). Moreover, 1.5% patients with GD had three associated autoimmune disorders. Interestingly, patients with Graves’ ophthalmopathy (GO) had another autoimmmune disorder more frequently (18.9%), with respect to GD patients without GO (15.6%). However the pattern of the associated autoimmune disorders in GD was not significantly different from that observed in AT patients. In conclusion, we suggest GD patients who are still sick, or who develop new unspecific symptoms (even if during an appropriate treatment of hyperthyroidism) should be appropriately screened for the presence of other autoimmune disorders

    Serum TSH Levels Normalisation in Patients Affected by Autoimmune Atrophic Gastritis, After the Switch From Oral L-T4 in Tablet Form to L-T4 in Liquid Formulation

    Get PDF
    Abstract Patients affected by autoimmune atrophic gastritis could have some issues in L-thyroxine (L-T4) absorption, due to drug malabsorption, induced by the increased gastric pH. Different factors influence L-T4 absorption, such as dietary habits, interference with other drugs, absorption kinetics, age of the patient, adherence to therapy, and others. We enrolled 36 patients affected by autoimmune atrophic gastritis with high serum thyrotropin (TSH) levels under therapy with L-T4 in the tablet formulation. L-T4 tablets were changed to an oral liquid L-T4 preparation, maintaining the same dose. The switch from L-T4 in tablet formulation to the liquid one, at the same L-T4 dosage, led to the normalisation/reduction of circulating TSH levels. Then 14 patients, who were switched back again to receive L-T4 in tablets (with the same dose), had a worsening of TSH values, falling in the hypothyroid range. In conclusion, our findings led to hypothesize that the pH alteration issue caused by autoimmune atrophic gastritis could be overcome by the oral L-T4 liquid formulation administration

    Study design: Retrospective cohort study. Purpose: to assess the efficacy and safety of Hi-PoAD technique in patients with a major thoracic curve > 90°, < 25% of flexibility and deformity spread over more than five vertebral levels. Methods: retrospective review of AIS patients with a major thoracic curve (Lenke 1-2-3) > 90°, with < 25% of flexibility and deformity spread over more than five vertebral levels. All were treated via the Hi-PoAD technique. Radiographic and clinical score data were collected pre-operatively, operatively, at 1 year, 2 years and at last follow-up (2 years minimum). Results: 19 patients were enrolled. A 65.0% correction rate of the main curve was achieved, from 101.9° to 35.7° (p < 0.001). The AVR reduced from 3.3 to 1.3. The C7PL/CSVL reduced from 1.5 to 0.9 cm (p = 0.013). Trunk Height increased from 31.1 to 37.0 cm (p < 0.001). At the final follow-up no significant changes, except from an improvement in C7PL/CSVL (from 0.9 cm to 0.6 cm; p = 0.017). SRS-22 increased in all patients, from 2.1 to 3.9 at 1 year of follow-up (p < 0.001). 3 patients had a transient drop of MEP and SEP during maneuver and were managed with temporary rods and a second surgery after 5 days. 2 of these 3 cases (66.7%) had a Total-Deformity Angular Ratio (T-DAR) > 25; conversely, among patients who had a one-stage procedure, only 1 (6.2%) had a T-DAR > 25 (p = 0.008). Conclusions: The Hi-PoAD technique proved to be a valid alternative for the treatment of severe, rigid AIS involving more than 5 vertebral bodies. Study design: Retrospective comparative cohort study. Level of evidence: III

    Frailty Influence on Postoperative Surgical Site Infections After Surgery for Degenerative Spine Disease and Adult Spine Deformity. Can a Frailty Index be a Valuable Summary Risk Indicator? A Systematic Review and Metanalysis of the Current Literature

    Get PDF
    Study design: Metanalysis. Objective: Surgical site infections (SSI) is one of the commonest postoperative adverse events after spine surgery. Frailty has been described as a valuable summary risk indicator for SSI in spine surgery. The aim of this metanalysis is to evaluate the influence of frailty on postoperative SSI in this cohort and provide hints on which index can predict the risk of SSI. Methods: Papers describing the postoperative SSI rate in adult degenerative spine disease or adult spine deformity patients with varying degrees of frailty were included in the analysis. The SSI rate in different grades of frailty was considered for outcome measure. Meta-analysis was performed on studies in whom data regarding patients with different levels of frailty and occurrence of postoperative SSI could be pooled. P < .05 was considered significant. Results: 16 studies were included. The frailty prevalence measured using mFI-11 ranged from 3% to 17.9%, these values were inferior to those measured with mFI-5. Significant difference was found between frail and non-frail patients in postoperative SSI rate at metanalysis (z = 5.9547, P < .0001 for mFI-5 and z = 3.8334, P = .0001 for mFI-11). Conclusion: This is the first meta-analysis to specifically investigate the impact of frailty, on occurrence of SSI. We found a relevant statistical difference between frail and non-frail patients in SSI occurrence rate. This is a relevant finding, as the ageing of population increases alongside with spine surgery procedures, a better understanding of risk factors may advance our ability to treat patients while minimizing the occurrence of SSI

    Advancements in the treatment of hypothyroidism with L-T4 liquid formulation or soft gel capsule: an update

    Get PDF
    INTRODUCTION: The most recent advance concerning levothyroxine (L-T4) therapy is the development of novel oral formulations: the liquid preparation, and the soft gel capsule. AREAS COVERED: This review evaluates the most recent clinical studies about these new formulations. The liquid formulation has been shown to overcome: the food and beverages intereference with L-T4 tablets absorption, caused by food or coffee at breakfast; malabsorption induced by the increased gastric pH, resulting from atrophic gastritis, or due to proton-pump inhibitors; and malabsorption after bariatric surgery. The use of liquid L-T4 has been studied also in pregnancy, newborns and infants, suggesting a better bioequivalence than tablets. Finally, liquid L-T4 is more active than tablets in the control of thyroid-stimulating hormone (TSH) in hypothyroid patients without malabsorption, drug interference, or gastric disorders, leading to a hypothesized higher absorption of liquid L-T4 also in these patients. Few studies have evaluated soft gel L-T4 with promising results in patients with malabsorption related to coffee or gastritis. EXPERT OPINION: Liquid L-T4 (and soft gel capsules) are more active than the tablet L-T4 in the control of TSH in hypothyroid patients with gastric disorders, malabsorption, or drug interference, but also in patients without absorption disorders

    New Targeted Therapies for Thyroid Cancer

    Get PDF
    The increasing incidence of thyroid cancer is associated with a higher number of advanced disease characterized by the loss of cancer differentiation and metastatic spread. The knowledge of the molecular pathways involved in the pathogenesis of thyroid cancer has made possible the development of new therapeutic drugs able to blockade the oncogenic kinases (BRAF V600E, RET/PTC) or signaling kinases [vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptors (PDGFR)] involved in cellular growth and proliferation. Some clinical trials have been conducted showing the ability of targeted therapies (sorafenib, sunitinib, axitinib, imanitib, vandetanib, pazopanib, gefitinib) in stabilizing the course of the disease. Until now, however, no consensus guidelines have been established for patient selection and more data on toxicities and side effects are needed to be collected
