RESUMO
BACKGROUND: Disseminated intravascular coagulation (DIC) is a rare but serious complication of pediatric scoliosis surgery; sparse current evidence warrants more information on causality and prevention. This systematic review sought to identify incidence of DIC in pediatric patients during or shortly after corrective scoliosis surgery and identify any predictive factors for DIC. METHODS: Medline/PubMed, EMBASE, and Ovid databases were systematically reviewed through July 2017 to identify pediatric patients with DIC in the setting of scoliosis surgery. Patient demographics, medical history, surgery performed, clinical course, suspected causes of DIC, and outcomes were collected. RESULTS: Eleven studies met inclusion criteria. Thirteen cases from 1974 to 2012 (mean age: 15.3 ± 4.3 years, 72% women) were identified, with neuromuscular (n = 7; 54%) scoliosis as the most common indication. There were no prior bleeding disorder histories; all preoperative labs were within normal limits. Procedures included 8 posterior segmental fusions (54%), 3 Harrington rods (31%), 1 Cotrel-Dubousset, and 1 unit rod. Eight patients experienced DIC intraoperatively and 5 patients experienced DIC postoperatively. Probable DIC causes included coagulopathy following intraoperatively retrieved blood reinfusion, infection from transfusion, rhabdomyolysis, hemostatic matrix application, heparin use, and hypovolemic shock. Most common complications included increased intraoperative blood loss (n = 8) and hypotension (n = 7). The mortality rate was 7.69%; one fatality occurred in the acute postoperative period. CONCLUSIONS: Prior bleeding disorder status notwithstanding, this review identified preliminary associations between variables during corrective scoliosis surgery and DIC incidence among pediatric patients, suggesting multiple etiologies for DIC in the setting of scoliosis surgery. Further investigation is warranted to quantify associated risk. CLINICAL RELEVANCE: This study brings awareness to a previously rarely discussed complication of pediatric scoliosis surgery. Further cognizance of DIC by scoliosis surgeons may help identify and prevent causes thereof.
RESUMO
STUDY DESIGN: Retrospective review of a prospectively collected database. OBJECTIVES: This preliminary investigation sought to identify the quality of care adolescent idiopathic scoliosis (AIS) patients from our large, underserved community had received before presenting at this institution's clinic. SUMMARY OF BACKGROUND DATA: AIS affects 1% to 4% of children between ages 10 and 16. Barriers to health care for patients in underserved populations have not been well studied. METHODS: Patients who visited a single surgeon's clinic for primary AIS between June 2016 and January 2017 were enrolled. Patients had 36-inch full-spine radiographs and completed a survey of demographics, prior AIS care received (screening, bracing, etc), socioeconomic parameters, and patient-reported outcomes (PROs; Scoliosis Research Society [SRS]-30 Questionnaire and Body Image Disturbance Questionnaire [BIDQ]). Parametric and nonparametric analyses were used and percentages and mean/median values were reported. RESULTS: 47 patients (age: 15 ± 3 years; 82.7% female) were included. Overall, 25.5% of patients reported a family history of scoliosis, and 42.6% had no prior knowledge of scoliosis. Per Scoliosis Research Society (SRS) recommendations, 15 patients required observation (main Cobb angle: <25°), 22 patients were eligible for bracing (25°-45°), and 10 patients were surgical candidates (>45°). In addition, 21.3% of all patients were never screened for scoliosis; of these, 50% had a main scoliosis curve >25°. Seventy percent of surgical candidates never wore a brace, and 59.3% of screened patients who were eligible for bracing were not braced at initial presentation. Patients who were left unbraced when eligible exhibited worse BIDQ scores (1.7 vs. 1.4, p < .05). CONCLUSIONS: One of five children in our population was never screened for scoliosis, and nearly three of five children did not receive optimal care as recommended by SRS. AIS patients in our inner-city populations are potentially at risk of continuing to experience a significant disadvantage in health care access. LEVEL OF EVIDENCE: Level IV case series.

Rheumatoid arthritis (RA) patients have nearly twice the risk of cardiovascular disease (CVD) compared to the general population. We aimed to assess, in a predominantly Black population, the prevalence of traditional and RA-specific CVD risk factors and therapeutic patterns. Utilizing ICD codes, we identified 503 RA patients ≥18 years old who were seen from 2010 to 2017. Of them, 88.5% were Black, 87.9% were women and 29.4% were smokers. CVD risk factors (obesity, diabetes, hypertension, dyslipidemia) were higher than in previously reported White RA cohorts. Eighty-seven percent of the patients had at least one traditional CVD risk factor, 37% had three or more traditional CVD risk factors and 58% had RA-specific risk factors (seropositive RA, >10 years of disease, joint erosions, elevated inflammatory markers, extra-articular disease, body mass index (BMI) < 20). CV outcomes (coronary artery disease/myocardial infarction, heart failure, atrial fibrillation and stroke) were comparable to published reports. Higher steroid use, which increases CVD risk, and lesser utilization of biologics (decrease CV risk) were also observed. Our Black RA cohort had higher rates of traditional CVD risk factors, in addition to chronic inflammation from aggressive RA, which places our patients at a higher risk for CVD outcomes, calling for revised risk stratification strategies and effective interventions to address comorbidities in this vulnerable population.
RESUMO
Comparing risks against benefits of adolescent idiopathic scoliosis (AIS) patients participating in sports represents a controversial topic in the literature. Previous studies have reported sports participation as a possible risk factor for AIS development, while others describe its functional benefits for AIS athletes. The objective of this study was to determine if sports participation had an impact on pain, function, mental status, and self-perception of deformity in patients and their parents. Patients had full spine radiographs and completed baseline surveys of demographics, socioeconomics, and patient-reported outcomes (PRO): Scoliosis Research Society (SRS)-30, Body Image Disturbance Questionnaire, and Spinal Appearance Questionnaire (SAQ: Children and Parent). Patients were grouped by their participation (sports) or nonparticipation (no-sports) in noncontact sports. Demographics, radiographic parameters, and PRO were compared using parametric/nonparametric tests with means/medians reported. Linear regression models identified significant predictors of PRO. Forty-nine patients were included (sports: n=29, no-sports: n=20). Both groups had comparable age, sex, BMI, bracing status, and history of physical therapy (all P>0.05). Sports and no-sports also had similar coronal deformity (major Cobb: 31.1° vs. 31.5°). Sagittal alignment profiles (pelvic incidence, pelvic incidence minus lumbar lordosis, thoracic kyphosis, and sagittal vertical axis) were similar between groups (all P>0.05). Sports had better SRS-30 (Function, Self-image, and Total) scores, SAQ-Child Expectations, and SAQ-Parent Total Scores (P<0.05). Regression models revealed major Cobb angle (ß coefficient: -0.312) and sports participation (ß coefficient: 0.422) as significant predictors of SRS-30 Function score (R=0.434, P<0.05). Our data show that for AIS patients with statistically similar bracing status and coronal and sagittal deformities, patients who participated in sports were more likely to have improved functionality, self-image, expectations, and parental perception of deformity. Further investigation is warranted to acquire a comprehensive understanding of the relationship between AIS and patient participation in sports. Maintaining moderate levels of physical activity and participating in safe sports may benefit treatment outcomes. Level of Evidence III - Retrospective Comparative Study.

OBJECTIVE It is becoming increasingly necessary for surgeons to provide evidence supporting cost-effectiveness of surgical treatment for cervical spine pathology. Anticipating surgical risk is critical in accurately evaluating the risk/benefit balance of such treatment. Determining the risk and cost-effectiveness of surgery, complications, revision procedures, and mortality rates are the most significant limitations. The purpose of this study was to determine independent risk factors for medical complications (MCs), surgical complications (SCs), revisions, and mortality rates following surgery for patients with cervical spine pathology. The most relevant risk factors were used to structure an index that will help quantify risk and anticipate failure for such procedures. METHODS The authors of this study performed a retrospective review of the National Inpatient Sample (NIS) database for patients treated surgically for cervical spine pathology between 2001 and 2010. Multivariate models were performed to calculate the odds ratio (OR) of the independent risk factors that led to MCs and repeated for SCs, revisions, and mortality. The models controlled for age (< and > 65 years old), sex, race, revision status (except for revision analysis), surgical approach, number of levels fused/re-fused (2-3, 4-8, ≥ 9), and osteotomy utilization. ORs were weighted based on their predictive category: 2 times for revision surgery predictors and 4 times for mortality predictors. Fifty points were distributed among the predictors based on their cumulative OR to establish a risk index. RESULTS Discharges for 362,989 patients with cervical spine pathology were identified. The mean age was 52.65 years, and 49.47% of patients were women. Independent risk factors included medical comorbidities, surgical parameters, and demographic factors. Medical comorbidities included the following: pulmonary circulation disorder, coagulopathy, metastatic cancer, renal failure, congestive heart failure, alcohol abuse, neurological disorder, nonmetastatic cancer, liver disease, rheumatoid arthritis/collagen vascular diseases, and chronic blood loss/anemia. Surgical parameters included posterior approach to fusion/re-fusion, ≥ 9 levels fused/re-fused, corpectomy, 4-8 levels fused/re-fused, and osteotomy; demographic variables included age ≥ 65 years. These factors increased the risk of at least 1 of MC, SC, revision, or mortality (risk of death). A total of 50 points were distributed among the factors based on the cumulative risk ratio of every factor in proportion to the total risk ratios. CONCLUSIONS This study proposed an index to quantify the potential risk of morbidity and mortality prior to surgical intervention for patients with cervical spine pathology. This index may be useful for surgeons in patient counseling efforts as well as for health insurance companies and future socioeconomics studies in assessing surgical risks and benefits for patients undergoing surgical treatment of the cervical spine.
