Objective The aim of this study was to evaluate the effectiveness of Chêneau brace in the management of idiopathic scoliosis. Methods This is a retrospective observational study according to SOSORT and SRS (Scoliosis Research Society) recommendations involving 48 girls with documented progressive idiopathic scoliosis, treated with Chêneau brace. A statistical analysis was performed with STATA MP11.2 to validate the obtained results. Results No patient needed surgery. The average curve angle measured in Cobb degrees passed from 27°± 6.7°at the beginning (T0), to 7.6°± 7.4°in brace (T1) (72 % of correction), to 8.5°± 8.6°(69 % of correction) at the end of treatment (T2), to 11.0°± 7.4°(59.3 % of correction) at final follow-up (mean 5 years and 5 months) (T3). Conclusion Conservative treatment with Chêneau brace and physiotherapy was effective in our hands for halting scoliosis progression in 100 % of patients.
In recent years, the application of fibrin sealant has been shown to be efficacious in the management of intraoperative and postoperative hemostasis. We designed a prospective randomized controlled clinical trial to assess the efficacy of two different dosages of fibrin sealant (5 and 10 ml) in patients undergoing total knee arthroplasty, as compared with the untreated control group. A total of 90 patients entered the study, randomly assigned to one of the three groups: treatment with 5 ml fibrin sealant (30 patients), with 10 ml fibrin sealant (30 patients) or no treatment (30 patients). A statistically significant difference in the mean reduction of hemoglobin concentrations was found on the first postoperative day in the treated groups as compared with the controls: 5 ml fibrin sealant (2.6 mg/dl) and 10 ml fibrin sealant (2.5 mg/dl) vs. controls (3.7 mg/dl) (P = 0.024). The mean number of blood transfusions was significantly lower in the treated groups: 5 ml (0.5) and 10 ml (0.3) of fibrin sealant vs. controls (1) (P = 0.0019). Functional recovery was also better in the treated groups: on the seventh day, the joint ROM (range of motion) was statistically superior in the 5 ml group (96.5°) and 10 ml group (98.8°) as compared with the controls (75.5°) (P < 0.0001). This study supports the efficacy of administering fibrin sealant in the perioperative management of bleeding after total knee arthroplasty and shows that a 5 ml dosage yields a comparable outcome to the 10 ml dosage previously reported in the literature.
Functional outcome of elderly patients treated for odontoid fracture. A multicenter study.
Purpose: Analysis of functional outcome of elderly patients with type II odontoid fractures treated conservatively in relation to their radiological outcome. Methods: 50 geriatric patients with type II odontoid fractures were treated with Aspen/Vista collars. On admission, each patient was assessed assigning ASA score, modified Rankin scale (mRS-pre) and Charlson Comorbidity Index (CCI). 12-15 months after treatment, functional evaluations were performed employing a second modified Rankin scale (mRS-post) together with Neck Disability Index (NDI) and Smiley Webster Pain Scale (SWPS). Radiological outcome was evaluated through dynamic cervical spine x-rays at 3 months and cervical spine CT scans 6 months after treatment. Three different conditions were identified: stable union, stable nonunion, unstable nonunion. Results: Among the 50 patients, 24 reached a stable union while 26 a stable nonunion. Comparing the two groups, no differences of ASA (p=0.60), CCI (p=0.85) and mRS-pre (p=0.14) were noted. Similarly, no differences of mRS-post (p=0.96), SWPS (p=0.85)
Hazards and potential complications associated with pedicle screw insertions have been reported. In contrast, complications due to implant removal are rarely described. An unreported case of acute vertebral body compression fracture following pedicle screw removal in a young man occurred during an episode of forceful coughing. Spinal implants need to be removed in cases of complications, pain or tissue irritation, and removal is mandatory when fixation involves L2 or the lower segments. Complications associated with spinal implant removal are rare but possible, and patients must be informed of this potential risk.
IMPORTANCEOveractivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.ObjectiveTo determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.DESIGN, SETTING, AND PARTICIPANTSIn an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).INTERVENTIONSPatients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days.MAIN OUTCOMES AND MEASURESThe primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.RESULTSOn February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).CONCLUSIONS AND RELEVANCEIn this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.TRIAL REGISTRATIONClinicalTrials.gov Identifier: NCT02735707
BackgroundCompression injuries of the thoracolumbar spine without neurological impairment are usually treated with minimally invasive procedures. Intravertebral expandable implants represent an alternative strategy in fractures with low fragments’ displacement.MethodsPatients with A2, A3 and A4 fractures of the T10–L2 spinal segment without neurological impairment, fracture gap >2 mm, vertebra plana, pedicle rupture, pedicle diameter <6 mm, spinal canal encroachment ≥50%, and vertebral body spread >30% were treated with the SpineJack device. Patients with pathological/osteoporotic fractures were excluded. Demographic and fracture-related data were assessed together with vertebral kyphosis correction, vertebral height restoration/loss of correction and final kyphosis. The modified Rankin Scale (mRS), Oswestry Disability Index (ODI), Visual Analogue Scale (VAS), Smiley–Webster Pain Scale (SWPS) and EuroQol-5D (EQ-5D) were evaluated at 1 (-post), 6 and 12 months (-fup) after surgery. Statistical analysis was performed and p values ≤0.05 were considered significant.ResultsFifty-seven patients were included in the study. Patients aged >60 years reported worse kyphosis correction (<4°) with more postoperative complications, while vertebral plasticity in younger patients, fragmentation-related greater remodeling in A3/A4 fractures, and treatments within 7 days of trauma determined superior wedging corrections, with better EQ-5D-post and mRS-fup. Cement leakages did not affect functional outcome, while female gender and American Society of Anesthesiologists (ASA) score of 3–4 were associated with worse ODI-fup and VAS-fup. Although fracture characteristics and radiological outcome did not negatively influence the clinical outcome, A2 fracture was a risk factor for complications, thus indirectly compromising both the functional and radiological outcome.ConclusionWith spread of <30%, the SpineJack is an alternative to minimally invasive fixations for treating A3/A4 thoracolumbar fractures, being able to preserve healthy motion segments in younger patients and provide an ultra-conservative procedure for elderly and fragile patients.
