Etiology and treatment patterns of ruptured extracranial carotid artery aneurysm.

OBJECTIVE: Rupture of an extracranial carotid artery aneurysm (ECAA) is a very rare and life-threatening condition. To obtain a comprehensive view of previous and current management of ruptured ECAAs (rECAAs), we analyzed all cases reported since 1940 and two of our own cases. METHODS: We performed a comprehensive literature review of reports from the MEDLINE database on rECAAs and included two patients treated in our department. RESULTS: A total 58 reports of 74 rECAAs in 74 patients were analyzed. Their mean age was 50 years, and the male/female ratio was 2.2:1. Infection was the most common reported etiology (19 of 74; 26%), followed by connective tissue disorder (13 of 74; 18%), atherosclerosis (9 of 74; 12%), and previous trauma (5 of 74; 7%). For 28 patients (38%), information on the etiology was not available. Of the 74 patients, 24 (32%) had undergone reconstructive surgery, 10 (14%) had undergone endovascular treatment, 17 (23%) had undergone ligation, 2 (3%) had been treated conservatively, and 1 (1%) had died before receiving definite treatment. For 20 patients (27%), information on the treatment received was not available. The complications after reconstruction included carotid blowout (3 of 24 patients; 13%) and cranial nerve deficit (3 of 24 patients; 13%). Two patients (8%) had died of unrelated ECAA causes during long-term follow-up, and one patient (4%) had died of an ECAA-related cause within 30 days. After an endovascular approach, 1 of the 10 patients had developed a cranial nerve deficit. After ligation, five patients (29%) had experienced stroke, three of which were fatal. One conservatively treated patient had experienced no complications and one had died of an ECAA-related cause. CONCLUSIONS: The most common reported etiology for rECAA was infection. Reconstructive surgery was the most common approach and was safer than ligation, which carried a high risk of stroke. Endovascular treatment showed promising results, especially for distally located aneurysms; however, the number of patients has remained low.

National survey on the treatment of acute appendicitis in Spain during the initial period of the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic has had a significant impact on Spanish hospitals, which have had to allocate all available resources to treat these patients, reducing the ability to attend other common pathologies. The aim of this study is to analyze how the treatment of acute appendicitis has been affected. METHOD: A national descriptive study was carried out by an online voluntary specific questionnaire with Google Drive™ distributed by email by the Spanish Association of Surgeons (AEC) to all affiliated surgeons currently working in Spain (5203), opened from April 14th to April 24th. RESULTS: We received 337 responses from 170 centers. During the first month of the pandemic, the incidence of acute appendicitis decreased. Although conservative management increased, the surgical option has been the most used in both simple and complicated appendicitis. Despite the fact that the laparoscopic approach continues to be the most widely used in our services, the open approach has increased during this pandemic period. CONCLUSION: Highlight the contribution of this study in terms of knowledge of the status of the treatment of acute appendicitis during this first month of the pandemic, being able to serve for a better possible organization in future waves of the pandemic and a reorganization of current protocols and management of acute appendicitis in a pandemic situation.

Epidemiology and management of isolated blunt renal artery injuries.

BACKGROUND: Isolated blunt renal artery injury (BRAI) is uncommon. Treatment options include observation, nephrectomy, surgical reconstruction and endovascular stenting. Over the last decade, there has been an increasing use of angiointervention techniques in vascular trauma. Previous studies reported underutilization of endovascular stenting in BRAI, in favor of observation. The aim of this study was to examine the epidemiology and assess changes in the management of isolated BRAI over the last decade. METHODS: Patients with BRAI identified from the National Trauma Data Bank (2016-2017). Deaths in the emergency department, transferral from outside hospital, and those with associated high-grade kidney injuries were excluded. Demographics, type of renal artery injury, and renal artery management were analyzed. Multivariate analysis was used to identify independent factors associated with isolated BRAI. RESULTS: During the study period, there were 1,708,076 patients with blunt trauma and 873 (0.05%) of them had BRAI. After exclusions, 563 patients with isolated BRAI who met the criteria for inclusion in the analysis. Auto versus pedestrian mechanism and male sex were associated with the highest risk for isolated BRAI. Comorbidities, such as hypertension or diabetes, were not associated with an increased risk of BRAI. Seatbelt use had a protective effect against BRAI. In the majority of patients (534, 95%), the renal artery injury was treated with observation, 23 (4%) with nephrectomy, 5 (0.9%) with endovascular stent and 1 (0.2%) with open renal artery repair. Among the 103 patients with isolated major renal artery laceration, 91.2% were treated with observation, 7.8% with nephrectomy and 1% with stenting. CONCLUSION: Isolated blunt renal artery trauma is rare. The vast majority of patients with BRAI is managed with observation with only a small number undergoing endovascular intervention. Endovascular stenting utilization has remained very low and has not changed in the last decade.

A rare case of spontaneous otogenic pneumocephalus with pictorial illustration of temporal evolution.

Pneumocephalus is commonly seen on imaging in the setting of craniofacial trauma, skull base tumours, intracranial infection and after neurological intervention. Spontaneous pneumocephalus in the absence of these conditions is exceedingly rare, with only approximately 30 cases reported in the literature to date. Spontaneous otogenic pneumocephalus (SOP) is believed to occur as a result of anomalous communication between the intracranial space and a hyper-pneumatised temporal bone, with either positive extra-to-intracranial pressure or negative intracranial pressure gradient. These anomalous communicating channels may only become clinically apparent when triggered by episodes of acute increase in middle ear pressure during coughing, sneezing, Valsalva manoeuvre or significant change in atmospheric pressure. Patients may exhibit a wide range of neurological symptoms and the aim of treatment is to reduce the risk of complications such as infection and intracranial hypertension. Both conservative and neurosurgical approaches have been described. We report a case of SOP in which the patient was conservatively managed, and spontaneous resolution of pneumocephalus was documented on serial computed tomography (CT) scans. This unique case clearly demonstrates the natural history and temporal evolution of SOP without surgical intervention. This knowledge may potentially obviate the need for surgery, thus reducing morbidity and mortality in patients who are poor surgical candidates.

Bevacizumab as a surgery-sparing agent for spinal ependymoma in patients with neurofibromatosis type II: Systematic review and case.

Neurofibromatosis type 2 (NF2) is a rare, hereditary tumor syndrome, often requiring repeated surgeries for multiple lesions with significant cumulative morbidity. As such, non-operative management should be considered when possible for this patient population. The aim of this study is to provide a systematic review of the literature regarding this treatment strategy. A descriptive case of a patient in whom bevacizumab treatments enabled over 15 years of surgical postponement for a symptomatic spinal cord ependymoma is also provided. Evidence suggests that bevacizumab is a reasonable surgery-deferring option for cystic lesions, and it may be especially useful in NF2 patients to reduce cumulative morbidity.

A comparison of successful versus failed nonoperative treatment approaches in patients with degenerative conditions of the lumbar spine.

Identifying an optimal composition of nonoperative therapies to trial in patients suffering from degenerative lumbar spine conditions prior to surgical management remains challenging. Contrasting successful versus failed nonoperative treatment approaches may provide clinicians with valuable insight. The purpose of this study was to compare the nonoperative therapy regimens in degenerative lumbar spine disorder patients successfully managed conservatively versus patients who failed primary treatment and opted for lumbar fusion surgery. Clinical records from patients diagnosed with lumbar stenosis or spondylolisthesis from 2007 to 2017 were gathered from a comprehensive insurance database. Patients were separated into two cohorts: patients managed successfully with nonoperative therapies and patients who failed conservative therapy and underwent lumbar fusion surgery. Nonoperative therapy utilization by the two cohortswere collected across a 2-year surveillance window. A total of 531,980 adult patients with lumbar stenosis or spondylolisthesis comprised the base population. There were 523,031 patients (98.3%) successfully treated with conservative management alone, while 8,949 patients (1.7%) ultimately failed nonoperative management and opted for lumbar fusion.Conservative therapy failure rates were especially high in patients with a smoking history (2.1%) and those utilizing lumbar epidural steroid injections (LESIs) (3.7%). A greater percentage of patients who failed conservative management utilized opioid medications (p < 0.0001), muscle relaxants (p < 0.0001), and LESIs (p < 0.0001). Patients who failed nonoperative management spent more than double than the successfully treated cohort (failed cohort: $1806.49 per patient; successful cohort: $768.50 per patient). In a multivariate logistic regression model, smoking, obesity and prolonged opioid use were independently associated with failure of nonoperative treatment.

Where have all the appendicectomies gone?

INTRODUCTION: The COVID-19 pandemic stimulated a national lockdown in the UK. The public were advised to avoid unnecessary hospital attendances and health professionals were advised to avoid aerosol-generating procedures wherever possible. The authors hypothesised that these measures would result in a reduction in the number of patients presenting to hospital with acute appendicitis and alter treatment choices. METHODS: A multicentred, prospective observational study was undertaken during April 2020 to identify adults treated for acute appendicitis. Searches of operative and radiological records were performed to identify patients treated during April 2018 and April 2019 for comparison. RESULTS: A total of 190 patients were treated for acute appendicitis pre-lockdown compared with 64 patients treated during lockdown. Patients treated during the pandemic were more likely to have a higher American Society of Anesthesiology (ASA) score (p = 0.049) and to have delayed their presentation to hospital (2 versus 3 days, p = 0.03). During the lockdown, the use of computed tomography (CT) increased from 36.3% to 85.9% (p < 0.001), the use of an antibiotic-only approach increased from 6.2% to 40.6% (p < 0.001) and the rate of laparoscopic appendicectomy reduced from 85.3% to 17.2% (p < 0.001). The negative appendicectomy rate decreased from 21.7% to 7.1% during lockdown (p < 0.001). CONCLUSIONS: The COVID-19 lockdown was associated with a decreased incidence of acute appendicitis and a significant shift in the management approach. The increased use of CT allows the identification of simple appendicitis for conservative treatment and decreases the negative appendicectomy rate.

Clinical Presentation, Investigation Findings, and Treatment Outcomes of Spontaneous Intracranial Hypotension Syndrome: A Systematic Review and Meta-analysis.

Importance: Spontaneous intracranial hypotension (SIH) is a highly disabling but often misdiagnosed disorder. The best management options for patients with SIH are still uncertain. Objective: To provide an objective summary of the available evidence on the clinical presentation, investigations findings, and treatment outcomes for SIH. Data Sources: Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline-compliant systematic review and meta-analysis of the literature on SIH. Three databases were searched from inception to April 30, 2020: PubMed/MEDLINE, Embase, and Cochrane. The following search terms were used in each database: spontaneous intracranial hypotension, low CSF syndrome, low CSF pressure syndrome, low CSF volume syndrome, intracranial hypotension, low CSF pressure, low CSF volume, CSF hypovolemia, CSF hypovolaemia, spontaneous spinal CSF leak, spinal CSF leak, and CSF leak syndrome. Study Selection: Original studies in English language reporting 10 or more patients with SIH were selected by consensus. Data Extraction and Synthesis: Data on clinical presentation, investigations findings, and treatment outcomes were collected and summarized by multiple observers. Random-effect meta-analyses were used to calculate pooled estimates of means and proportions. Main Outcomes and Measures: The predetermined main outcomes were the pooled estimate proportions of symptoms of SIH, imaging findings (brain and spinal imaging), and treatment outcomes (conservative, epidural blood patches, and surgical). Results: Of 6878 articles, 144 met the selection criteria and reported on average 53 patients with SIH each (range, 10-568 patients). The most common symptoms were orthostatic headache (92% [95% CI, 87%-96%]), nausea (54% [95% CI, 46%-62%]), and neck pain/stiffness (43% [95% CI, 32%-53%]). Brain magnetic resonance imaging was the most sensitive investigation, with diffuse pachymeningeal enhancement identified in 73% (95% CI, 67%-80%) of patients. Brain magnetic resonance imaging findings were normal in 19% (95% CI, 13%-24%) of patients. Spinal neuroimaging identified extradural cerebrospinal fluid in 48% to 76% of patients. Digital subtraction myelography and magnetic resonance myelography with intrathecal gadolinium had high sensitivity in identifying the exact leak site. Lumbar puncture opening pressures were low, normal (60-200 mm H2O), and high in 67% (95% CI, 54%-80%), 32% (95% CI, 20%-44%), and 3% (95% CI, 1%-6%), respectively. Conservative treatment was effective in 28% (95% CI, 18%-37%) of patients and a single epidural blood patch was successful in 64% (95% CI, 56%-72%). Large epidural blood patches (>20 mL) had better success rates than small epidural blood patches (77% [95% CI, 63%-91%] and 66% [95% CI, 55%-77%], respectively). Conclusions and Relevance: Spontaneous intracranial hypotension should not be excluded on the basis of a nonorthostatic headache, normal neuroimaging findings, or normal lumbar puncture opening pressure. Despite the heterogeneous nature of the studies available in the literature and the lack of controlled interventional studies, this systematic review offers a comprehensive and objective summary of the evidence on SIH that could be useful in guiding clinical practice and future research.

Factors Associated with Early versus Delayed Expansion of Acute Subdural Hematomas Initially Managed Conservatively.

Acute subdural hematomas (ASDHs) are highly morbid and increasingly common. Hematoma expansion is a potentially fatal complication, and few studies have examined whether factors associated with hematoma expansion vary over time. To answer this, we performed a case-control study in a cohort of initially conservatively managed patients with ASDH. Two time periods were considered, early (<72 h from injury) and delayed (>72 h from injury). Cases were defined as patients who developed ASDH expansion in the appropriate period; controls were patients who had stable imaging. Associated factors were determined with logistic regression. We identified 68 cases and 237 controls in the early follow-up cohort. Early ASDH expansion was associated with coagulopathy (adjusted odds ratio [aOR] 2.3, 95 % CI: 1.2-4.5; p = 0.02), thicker ASDHs (aOR 1.1, 95% CI: 1.03-1.2; p = 0.006), additional intracranial lesions (aOR 3, 95% CI: 1.6-6.2; p = 0.002), no/minimal trauma history (aOR 0.4, 95% CI: 0.2-0.9; p = 0.03), and duration between injury and initial scan (aOR 0.9, 95% CI: 0.8-0.97; p = 0.04). In the delayed follow-up cohort, there were 41 cases and 126 controls. Delayed ASDH expansion was associated with older age (aOR 1.3 per 10 years, 95% CI: 1.1-1.6; p = 0.01), systolic blood pressure (SBP) >160 on hospital presentation (aOR 4.5, 95% CI: 1.8-11.3; p = 0.001), midline shift (aOR 1.5 per 1 mm, 95% CI: 1.3-1.9; p < 0.001), and convexity location (aOR 14.1, 95% CI: 2.6-265; p = 0.013). We conclude that early and delayed ASDH expansion are different processes with different associated factors, and that elevated SBP may be a modifiable risk factor of delayed expansion.

Pregnancy and delivery outcomes in women with rectovaginal endometriosis treated either conservatively or operatively.

OBJECTIVE: To study reproductive outcomes, and pregnancy and delivery complications after conservative or operative treatment of rectovaginal endometriosis during long-term follow-up. DESIGN: Retrospective cohort study. SETTING: University hospital. PATIENT(S): Women with rectovaginal endometriosis referred to hospital due to any indication from 2004 to 2013 (N = 543) who were treated initially either conservatively (group CONS, n = 183), or operatively (OPER, n = 360) either with resection of rectovaginal nodule (RVR, n = 192) or with concomitant bowel resection (BR, n = 132). INTERVENTION(S): Conservative or operative management. MAIN OUTCOME MEASURE(S): Clinical pregnancy rate, live-birth rate, and assessment of the complications during pregnancy and delivery. RESULTS(S): Between women in the CONS group or OPER group, no differences were found in either clinical pregnancy rate (56%, n = 102 vs. 50%, n = 181) or live-birth rate (48%, n = 87 vs. 42%, n = 153). Of the pregnancies, 64% (n = 65) and 49% (n = 89), respectively, started after medically assisted reproduction. No differences emerge in the subanalysis of women <40 years-old who wished to conceive. The most common pregnancy complication was preterm birth: 15% (n = 13) in the CONS group and 20% (n = 30) in the OPER group. The cesarean delivery rate also was high (46%, n = 40 vs. 49%, n = 76). Complications emerged in 21% (n = 10) versus 29% (n = 23) of vaginal deliveries and 45% (n = 18) versus 53% (n = 40) of cesarean deliveries. The most common delivery complication was excessive bleeding. The follow-up period was 4.9 years in the CONS group and 5.6 years in the OPER group. CONCLUSION(S): Women with rectovaginal endometriosis have comparable and good reproductive prognosis regardless of the treatment method.

Correlation of disease comorbidity with prescribed treatment among insured U.S. lymphedema patients.

OBJECTIVE: The objective of this study was to define the current forms of treatment in a contemporary population of lymphedema (LED) patients for LED related to breast cancer, the most prevalently diagnosed LED comorbidity in Western countries, and phlebolymphedema with venous leg ulcer (PLEDU), a sequela of chronic venous disease. The goals of LED therapy are to reduce edema, thereby improving function and related symptoms, and to improve skin integrity to prevent development of infection. Treatment is generally nonsurgical: conservative care, including complex physical therapy, manual lymphatic drainage, and compression bandaging; or pneumatic compression device (PCD) therapy by a simple nonprogrammable device or an advanced programmable device. METHODS: To determine the frequency of individual types of treatment for LED and their relationship to breast cancer-related lymphedema (BCRL) and PLEDU, we queried claims from a deidentified Health Insurance Portability and Accountability Act-compliant commercial administrative insurance database with >165 million members. A total of 26,902 patients identified with LED who had been enrolled with continuous medical benefits for 12 months before and after the index date for the complete years 2012 through 2016 were separated into four treatment categories: no treatment, conservative care, simple PCD (SPCD), and advanced PCD. LED treatment was related to the BCRL and PLEDU comorbidities. RESULTS: BCRL patients, who represented 32.1% of all study patients, made up 41% of all patients receiving conservative care and 24% of patients receiving PCD therapy. By contrast, PLEDU patients (9.6% of study patients) were proportionally under-represented in the conservative care group (7.8%) but composed a disproportionately high share of the PCD therapy group (17.7%). PLEDU patients represented 23.5% of all LED patients prescribed SPCD therapy, whereas BCRL patients composed 10.3% of total LED patient SPCD prescriptions (P < .001). CONCLUSIONS: Our analysis of a large health care administrative database showed clear differences between the way BCRL and PLEDU patients are treated. Compared with BCRL patients, PLEDU patients were less likely to receive conservative care and more likely to be prescribed SPCDs for pneumatic compression therapy. These differences suggest that lymphatic therapy may be undervalued for treatment of chronic venous swelling and prevention and treatment of PLEDU.

Use and Cost of Orthosis in Conservative Treatment of Acute Thoracolumbar Fractures: A Survey of European and North American Experts.

STUDY DESIGN: Survey study. OBJECTIVE: Assess practices and opinions of spine specialists from Europe and North America on orthosis use in adult patients with acute thoracolumbar (TL) fractures. Evaluate cost of the devices. SUMMARY OF BACKGROUND DATA: Although orthosis are traditionally used in conservative treatment of TL fractures, recent systematic reviews showed no benefit in patient's outcomes. METHODS: A search for contact authors with publications on spine fractures from all European and North American countries was performed. An online questionnaire was sent on demographic data, practice setting, mean number of fractures treated, use of orthosis upon choice for conservative treatment, and average orthosis cost. Data was analyzed based in world regions, economic rank of the country, and health expenditure. RESULTS: We received 130 answers, from 28 European and five North American countries. Most responders had more than 9 years of practice and worked at a public hospital. 6.2% did not prescribe a brace in any patient with acute TL fractures conservatively treated and 11.5% brace all patients. In a scale from 1 to 5, 21 considered that there is no/low benefit (1) and 14 that bracing is essential (5), with a mean of 3.18. Europeans use orthosis less commonly than North Americans (P < 0.05). Orthosis mean cost was $611.4 ±â€Š716.0, significantly higher in North America compared with Europe and in high income, when compared with upper middle income countries (both P < 0.05). Although hospital costs were not evaluated, orthosis is costlier when it involves admission of the patient (P < 0.05). An increase in orthosis cost associated with higher gross domestic product (GDP) per capita and higher health expenditure was found. CONCLUSION: More than 90% of spine specialists still use orthosis in conservative treatment of adult patients with acute TL fractures. Orthosis cost vary significantly between continents, and it is influenced by the country's economy.Level of Evidence: 4.

Factors Associated With Progression to Surgical Intervention for Lumbar Disc Herniation in the Military Health System.

STUDY DESIGN: Retrospective cohort. OBJECTIVE: To determine surgery-free survival of patients receiving conservative management of lumbar disc herniation (LDH) in the military healthcare system (MHS) and risk factors for surgical intervention. SUMMARY OF BACKGROUND DATA: Radiculopathy from LDH is a major cause of morbidity and cost. METHODS: The Military Data Repository was queried for all patients diagnosed with LDH from FY2011-2018; the earliest such diagnosis in a military treatment facility (MTF) was kept for each patient as the initial diagnosis. Follow-up time to surgical intervention was defined as the time from diagnosis to first encounter for lumbar microdiscectomy or lumbar decompression in either a MTF or in the civilian sector. The Military Data Repository was also queried for history of tobacco use at any time during MHS care, age at the time of diagnosis, sex, MHS beneficiary category, and diagnosing facility characteristics. Multivariable Cox proportional hazards models were used to evaluate the associations of patient and diagnosing facility characteristics with time to surgical intervention. RESULTS: A total of 84,985 MHS beneficiaries including 62,771 active duty service members were diagnosed with LDH in a MTF during the 8-year study period. A total of 10,532 (12.4%) MHS beneficiaries, including 7650 (10.9%) active duty, failed conservative management onto surgical intervention with lumbar microdiscectomy or lumbar decompression. Median follow-up time of the cohort was 5.2 (interquartile range 2.6, 7.5) years. Among all healthcare beneficiaries, several patient-level (younger age, male sex, and history of tobacco use) and facility-level characteristics (hospital vs. clinic and surgical care vs. primary care clinic) were independently associated with higher risk of surgical intervention. CONCLUSION: LDH compromises military readiness and negatively impacts healthcare costs. MHS beneficiaries with LDH have a good prognosis with approximately 88% of patients successfully completing conservative management. However, strategies to improve outcomes of conservative management in LDH should address risks associated with both patient and facility characteristics.Level of Evidence: 4.

Surgical versus conservative treatment of unilateral subaxial non-subluxed facet fractures: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Unilateral subaxial non-subluxed facet fractures (USNSFF) are a pathology seen in traumatic events such as motor vehicle accidents. Management involves either rigid collar bracing or surgical intervention. There currently is no consensus on the treatment of these injuries; this review aims to examine the extant data for recommendations as to which treatment is more effective. METHODS: MEDLINE, Scopus, and the Cochrane trial register were all searched on January 16, 2020, comparing outcomes for surgical and conservative therapy for USNSFF. The meta-analysis examined rates of treatment failure (need for subsequent operative management) in conservative versus surgical management. The meta-analysis was performed using a random effects model, with visualization in forest and L'Abbé plots. RESULTS: We identified six retrospective studies describing 270 patients, with three studies describing 137 patients used in the meta-analysis. Overall, a surgical success rate of 97.7 % and a non-operative success rate of 79.7 % was observed. A random effects model risk ratio of 1.66 (95 % CI: 0.61-4.52) was obtained, suggesting efficacy of surgical management over conservative management. CONCLUSION: The need for surgical intervention subsequent to initial management in the treatment of USNSFF was found to be lower in surgical treatment in contrast to conservative management. However, the studies that were included in the meta-analysis had patient cohorts with much higher rates of neurological deficit and ligamentous injury on presentation, indicating that these may be prognostic indicators of conservative management failure. Furthermore, those that did fail conservative management did not develop severely debilitating conditions. Accordingly, conservative treatment is generally sufficient as a first step in a majority of cases of USNSFF lacking neurological deficit or ligamentous involvement.

National osteoarthritis strategy brief report: Advanced care.

BACKGROUND: Osteoarthritis (OA) is one of the most common chronic joint diseases and a leading cause of pain and disability in Australia. A National Osteoarthritis Strategy (the Strategy) was developed to outline a national plan to achieve optimal health outcomes for people at risk of, or with, OA. OBJECTIVE: This article focuses on the theme of advanced care of patients with OA within the Strategy. DISCUSSION: The Strategy was developed in consultation with a leadership group, thematic working groups, an implementation advisory committee, multisectoral stakeholders and the public. This Strategy identified three priorities in advanced care for osteoarthritis. In brief, these include surgical decision making, referral for evidence-informed non-surgical alternatives and surgical services. A set of goals within these priority areas and strategies was also proposed by the working group in consultation with stakeholders nationwide. Peak arthritis bodies and major healthcare professional associations currently endorse the Strategy.

Orthosis in Thoracolumbar Fractures: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

STUDY DESIGN: Systematic review and meta-analysis of randomized controlled trial (RCT). OBJECTIVE: The aim of this study was to evaluate radiological and clinical outcomes of acute traumatic thoracolumbar fractures in skeletally mature patients treated with orthosis, versus no immobilization. SUMMARY OF BACKGROUND DATA: Orthosis is traditionally used in conservative treatment of thoracolumbar fractures. However, recent studies suggest no benefit, and a possible negative impact in recovery. METHODS: Databases were searched from inception to June 2019. Studies were selected in two phases by two blinded reviewers; disagreements were solved by consensus. Inclusion criteria were: RCT; only patients with acute traumatic thoracolumbar fractures; primary conservative treatment; comparison between orthosis and no orthosis. Exclusion criteria were inclusion of nonacute fractures, patients with other significant known diseases and comparison of groups different than use of an orthosis. Two independent reviewers performed data extraction and quality assessment. Fixed-effects models were used upon no heterogeneity, and random-effects model in the remaining cases. A previous plan for extraction of radiological (kyphosis progression; loss of anterior height) and clinical (pain; disability; length of stay) outcomes was applied. PRISMA guidelines were followed. RESULTS: Eight articles/five studies were included (267 participants). None reported significant differences in pain, kyphosis progression, and loss of anterior height. One reported a better ODI with orthosis at 12 but not at 24 weeks. No other study reported differences in disability. All authors concluded an equivalence between treatments.Meta-analysis showed a significant increase of 3.47days (95% confidence interval 1.35-5.60) in mean admission time in orthosis group. No differences were found in kyphosis at 6 and 12 months; kyphosis progression between 0 to 6 and 0 to 12 months; loss of anterior height 0 to 6 months; VAS for pain at 6 months; VAS change 0 to 6 months. CONCLUSION: Orthosis seems to add no benefit in conservative treatment of acute thoracolumbar fractures. This should be considered in guidelines and reviews of health care policies.

Temporal trends in the number of men electing for conservative management for low-risk prostate cancer in the United States.

BACKGROUND: Concurrent with the decrease in the number of men diagnosed with prostate cancer (PCa), the proportion of men with low-risk PCa managed conservatively (active surveillance or watchful waiting) has increased in the United States. We aimed to determine whether this increase is a result of more men being managed conservatively or rather a higher proportion of the diminishing number of low-risk PCa managed this way. METHODS: The SEER "Prostate Watchful Waiting Database" identified men managed initially with conservative management between 2010 and 2016. Men > 40 years old who were diagnosed with low-risk (Gleason score 3 + 3, T1-T2a, PSA level < 10 ng/mL) PCa were included. Age-standardized and age-specific PCa incidence and conservative management rates were calculated per 100,000 man-years. The annual percent change in rates for the entire time period was also calculated. RESULTS: The incidence of low-risk PCa declined by 11.8% per year (95% confidence interval [CI] -15.4% to -8.0%), whereas the number of men assigned to conservative management for low-risk disease did not increase significantly, rising by +3.7% per year (95% CI -0.7% to 8.4%). In age-specific analysis, the number of men < 60 years and those who were 60-69 years managed conservatively increased by +9.6% per year (95% CI 2.7% to 16.9%) and 4.5% per year (95% CI 0.1% to 9.1%), respectively, whereas the number of men ≥ 70 years electing conservative management remained stable at -4% per year (95% CI -11.2% to 3.7%). CONCLUSIONS: The number of men electing conservative management has remained largely stable between 2010 and 2016, despite an increase in the proportion of low-risk PCa managed in this manner.

Deep Brain Stimulation Results in Greater Symptomatic Improvement in Tourette Syndrome than Conservative Measures: A Meta-Analysis.

INTRODUCTION: Deep brain stimulation (DBS) has emerged as a safe and effective therapy for refractory Tourette syndrome (TS). Recent studies have identified several neural targets as effective in reducing TS symptoms with DBS, but, to our knowledge, none has compared the effectiveness of DBS with conservative therapy. METHODS: A literature review was performed to identify studies investigating adult patient outcomes reported as Yale Global Tic Severity Scale (YGTSS) scores after DBS surgery, pharmacotherapy, and psychotherapy. Data were pooled using a random-effects model of inverse variance-weighted meta-analysis (n = 168 for DBS, n = 131 for medications, and n = 154 for behavioral therapy). RESULTS: DBS resulted in a significantly greater reduction in YGTSS total score (49.9 ± 17.5%) than pharmacotherapy (22.5 ± 15.2%, p = 0.001) or psychotherapy (20.0 ± 11.3%, p < 0.001), with a complication (adverse effect) rate of 0.15/case, 1.13/case, and 0.60/case, respectively. CONCLUSION: Our data suggest that adult patients with refractory TS undergoing DBS experience greater symptomatic improvement with surprisingly low morbidity than can be obtained with pharmacotherapy or psychotherapy.
