Clinical Characteristics and Surgical Outcomes of 2542 Patients with Spinal Schwannomas: A Systematic Review and Meta-Analysis.

OBJECTIVE: This study was conducted to systematically analyze the data on the clinical features, surgical treatment, and outcomes of spinal schwannomas. METHODS: We conducted a systematic review and meta-analysis under the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of bibliographic databases from January 1, 2001, to May 31, 2021, yielded 4489 studies. Twenty-six articles were included in our final qualitative systematic review and quantitative meta-analysis. RESULTS: Analysis of 2542 adult patients' data from 26 included studies showed that 53.5% were male, and the mean age ranged from 35.8 to 57.1 years. The most common tumor location was the cervical spine (34.2%), followed by the thoracic spine (26.2%) and the lumbar spine (18.5%). Symptom severity was the most common indicator for surgical treatment, with the most common symptoms being segmental back pain, sensory/motor deficits, and urinary dysfunction. Among all patients analyzed, 93.8% were treated with gross total resection, which was associated with better prognosis and less chance of recurrence than subtotal resection. The posterior approach was the most common (87.4% of patients). The average operative time was 4.53 hours (95% confidence interval [CI], 3.18-6.48); the average intraoperative blood loss was 451.88 mL (95% CI, 169.60-1203.95). The pooled follow-up duration was 40.6 months (95% CI, 31.04-53.07). The schwannoma recurrence rate was 5.3%. Complications were particularly low and included cerebrospinal fluid leakage, wound infection, and the sensory-motor deficits. Most of the patients experienced complete recovery or significant improvement of preoperative neurological deficits and pain symptoms. CONCLUSIONS: Our analysis suggests that segmental back pain, sensory/motor deficits, and urinary dysfunction are the most common symptoms of spinal schwannomas. Surgical resection is the treatment of choice with overall good reported outcomes and particularly low complication rates. gross total resection offers the best prognosis with the slightest chance of tumor recurrence and minimal risk of complications.

The Impact of Physical Therapy After Lumbar Fusion Surgery.

STUDY DESIGN: Retrospective Cohort. OBJECTIVE: To determine if outcomes varied between patients based on physical therapy (PT) attendance after lumbar fusion surgery. SUMMARY OF BACKGROUND DATA: The literature has been mixed regarding the efficacy of postoperative PT to improve disability and back pain, as measured by patient-reported outcome measures. Given the prevalence of PT referrals and lack of high-quality evidence, there is a need for additional studies investigating the efficacy of PT after lumbar fusion surgery to aid in developing robust clinical guidelines. METHODS: We retrospectively identified patients receiving lumbar fusion surgery by current procedural terminology codes and separated them into 2 groups based on whether PT was prescribed. Electronic medical records were reviewed for patient and surgical characteristics, PT utilization, and surgical outcomes. Patient-reported outcome measures (PROMs) were identified and compared preoperatively, at 90 days postoperatively and one year postoperatively. RESULTS: The two groups had similar patient characteristics and comorbidities and demonstrated no significant differences between readmission, complication, and revision rates after surgery. Patients that attended PT had significantly more fused levels (1.41 ± 0.64 vs. 1.32 ± 0.54, P =0.027), longer operative durations (234 ± 96.4 vs. 215 ± 86.1 min, P =0.012), and longer postoperative hospital stays (3.35 ± 1.68 vs. 3.00 ± 1.49 days, P =0.004). All groups improved similarly by Oswestry Disability Index, short form-12 physical and mental health subsets, and back and leg pain by Visual Analog Scale at 90-day and 1-year follow-up. CONCLUSION: Our data suggest that physical therapy does not significantly impact PROMs after lumbar fusion surgery. Given the lack of data suggesting clear benefit of PT after lumbar fusion, surgeons should consider more strict criteria when recommending physical therapy to their patients after lumbar fusion surgery. LEVEL OF EVIDENCE: Level-Ⅲ.

Full-endoscopic foraminotomy in low-grade degenerative and isthmic spondylolisthesis: a patient-specific tailored approach.

PURPOSE: To describe the surgical technique and methodology to successfully plan and execute an endoscopic foraminotomy in patients with isthmic or degenerative spondylolisthesis, according to each patient's unique characteristics. METHODS: Thirty patients with degenerative or isthmic spondylolisthesis (SL) with radicular symptoms were included from March 2019 to September 2022. Treating physician registered patients' baseline and imaging characteristics, as well as preoperative back pain VAS, leg pain VAS and ODI. Subsequently, authors treated the included patients with an endoscopic foraminotomy according to a "patient-specific" tailored approach. RESULTS: Nineteen patients (63.33%) had isthmic SL and 11 patients (36.67%) had degenerative SL. 75.86% of the cases had a Meyerding Grade 1 listhesis. One of the transforaminal foraminotomies with lateral recess decompression in degenerative SL had to be aborted because of intense osseous bleeding. Of the remaining 29 patients, one patient experienced recurrence of the sciatica pain that required subsequent reintervention and fusion. No other intraoperative or post-operative complications were observed. None of the patients developed post-operative dysesthesia. In 86.67% of the patients, the foraminotomy was implemented using a transforaminal approach. In the remaining 13.33% of the cases, an interlaminar contralateral approach was used. Lateral recess decompression was performed in half of the cases. Mean follow-up time was 12.69 months, reaching a maximum of 40 months in some patients. Outcome variables such as VAS for leg and back pain, as well as ODI, showed statistically significant reduction since the 3-month follow-up visit. CONCLUSION: In the presented case series, endoscopic foraminotomy achieved satisfactory outcomes without sacrificing segmental stability. The proposed patient-specific "tailored" approach allowed to successfully design and execute the surgical strategy to perform an endoscopic foraminotomy through transforaminal or interlaminar contralateral approaches.

Factors associated with the incidence and worsening of back pain during the first wave of COVID-19 in Brazil. / Fatores associados à incidência e à piora do problema de coluna durante a primeira onda da COVID-19 no Brasil.

The article aims to estimate the incidence and worsening of back pain (BP) during the first wave of COVID-19 in Brazil, as well as to investigate demographic, socioeconomic factors and associated changes in living conditions. ConVid - Behavior Research, applied between April and May 2020, was used as data source. The number and distribution of respondents who developed BP and those who had a worsening of the preexisting problem, their 95% confidence intervals and Pearson's Chi-square test were estimated. The odds ratio of developing BP or worsening a preexisting problem was also estimated using multiple logistic regression models. Pre-existing BP was reported by 33.9% (95%CI 32.5-35.3) of respondents and more than half (54.4%; 95%CI 51.9-56.9) had worsened. The cumulative incidence of BP in the first wave of the pandemic was 40.9% (95%CI 39.2-42.7). Being a woman, the perceived increase in housework and the frequent feeling of sadness or depression were associated with both outcomes. Socioeconomic factors were not associated with any of outcome. The high incidence and worsening of BP during the first wave reveal the need for studies in more recent periods, given the long duration of the pandemic.

O artigo tem como objetivo estimar a incidência e o agravamento do problema de coluna (PC) durante a primeira onda da COVID-19 no Brasil, bem como investigar os fatores demográficos, socioeconômicos e as mudanças nas condições de vida associadas. Utilizou-se a ConVid - Pesquisa de Comportamentos, realizada entre abril e maio de 2020, como fonte de dados. Estimou-se o número e a distribuição dos entrevistados que desenvolveram PC e a dos que tiveram agravamento no problema preexistente, seus intervalos de 95% de confiança e o teste qui-quadrado de Pearson. Estimou-se também a razão de chance de desenvolver PC ou ter piora de problema preexistente por meio de modelos de regressão logística múltipla. O PC preexistente foi reportado por 33,9% (IC95% 32,5-35,3) dos entrevistados e mais da metade (54,4%; IC95% 51,9-56,9) teve piora do quadro. A incidência cumulativa de PC na primeira onda da pandemia foi de 40,9% (IC95% 39,2-42,7). Ser mulher, o aumento percebido do trabalho doméstico e o sentimento frequente de tristeza ou depressão foram associados a ambos os desfechos. Os fatores socioeconômicos não foram associados a nenhum dos desfechos. A alta incidência e agravamento do PC durante a primeira onda revelam a necessidade de estudos em períodos mais recentes, dada a longa duração da pandemia.

Risk Factors for Back Pain among Southern Brazilian School Children: A 6-Year Prospective Cohort Study.

Risk factors associated with back pain vary in different countries. Given the lack of studies in Latin America, our study aimed to assess back pain and its associated factors for six years in Southern Brazilian school children. All children attending the fifth grade of Teutônia, Brazil, were invited to participate in the study. Only schoolchildren who did not report back pain were included in the first assessment. The schoolchildren completed the Back Pain and Body Posture Evaluation Instrument (BackPEI) during three assessments (2011, 2014, and 2017). BackPEI assesses the presence of back pain and possible associated risk factors (postural, behavioral, and sociodemographic). Generalized estimated equations (GEE) were used to perform a Poisson regression model with robust variance for longitudinal analysis. After six years of follow-up, 75 schoolchildren completed all the assessments. The risk factors associated with back pain were spending more than six hours daily watching television, lifting objects from the ground adopting an inadequate posture, using another backpack type different from those with two straps, and carrying a backpack in an asymmetric way. These results are important in guiding the planning of public policies to minimize this public health problem.

Back pain occurred due to changes in routinary activities among Brazilian schoolteachers during the COVID-19 pandemic.

OBJECTIVE: This study's main objective was to investigate the emergence of back pain as a consequence to changes in usual activities due to the COVID-19 pandemic among teachers in public schools in the state of Minas Gerais, Brazil. METHODS: A cross-sectional study was conducted among 15,276 schoolteachers using an online questionnaire. The variables included sociodemographic and occupational data, health situation, habits and behaviors during the COVID-19 pandemic. Bivariate analyses using Pearson's chi-square test and multiple analyses using Poisson regression were performed to identify the associated factors. RESULTS: About 58% of schoolteachers reported back pain due to changes in routine activities during the pandemic. The adjusted model showed a correlation between back pain and female sex, longer working hours, overwork, difficulties concerning distance working, negative changes in health status and quality of sleep; frequent feeling of sadness, depression, or anxiety; use of medications to relax, sleep or against stress/anxiety/depression; physical inactivity or negative changes in the practice of physical activities; increased body weight; reduction of leisure time; increased time of use of computer or tablet and overload of housework. CONCLUSION: During the COVID-19 pandemic, schoolteachers reported a high prevalence of emergence of back pain, which delineates a contradiction in terms: on the one hand, distance education allows social distancing that contributes to the preservation of teachers' health by reducing the risk of contamination by COVID-19. On the other hand, it imposes new demands that-in disagreement with working conditions-can threaten the health of these workers.

Alterações posturais e nível de dor em mães com bebês de colo: um estudo transversal / Postural changes and pain level in mothers with lap babies: a transversal study

INTRODUÇÃO: O período gestacional caracteriza-se como um momento de grandes eventos fisiológicos, assim como também o período puerperal, que traz consigo grandes mudanças físicas e psicológicas. OBJETIVO: Avaliar a prevalência de alterações posturais e nível de dor em mães com bebês de colo. MATERIAL E MÉTODOS: Pesquisa transversal, de caráter descritivo e abordagem quantitativa, que foi desenvolvida com mães que participavam do acompanhamento de puericultura e aleitamento materno durante novembro de 2018 numa frequência de três vezes por semana. Para coleta dos dados, utilizou-se um formulário sociodemográfico para colher algumas informações pessoais; o Instrumento de Avaliação Postural (IAP) a Escala Analógica Visual de Dor (EVA). Os dados categóricos foram apresentados através de frequência simples e absolutas, seguidos da utilização do teste Qui-quadrado (χ²) de Pearson para a associação entre o nível de dor com as variáveis dependentes. RESULTADOS: A idade das mães manteve-se entre 18 e 35 anos, com nível de escolaridade completo, e a maioria sem atividade ocupacional. Observou-se que, apesar do estudo não apresentar associação significativa entre os hábitos posturais e o nível de dor, este sintoma esteve presente em 73,5 % das mulheres e prevaleceu em níveis de moderada (n=26) à intensa (n=24), mantendo uma relação discreta com alguns tipos de desvios. A alteração postural mais prevalente foi a hiperlordose lombar (69,1%). CONCLUSÃO: Foi possível perceber que a dor e os desvios posturais estão presentes em mulheres com bebês de colo, sendo necessário pensar em intervenções com esse enfoque para este grupo.

INTRODUCTION: The gestational period is characterized as a time of great physiological events and the puerperal period, which brings with it great physical and psychological changes. OBJECTIVE: To evaluate the prevalence of postural changes and pain levels in mothers with babies in arms. MATERIAL AND METHODS: Cross-sectional research, descriptive and quantitative approach, which was developed with mothers who participated in monitoring childcare and breastfeeding during November 2018 at a frequency of three times a week. For data collection, a sociodemographic form was used to collect some personal information; the Postural Assessment Instrument (IAP) the Visual Analog Pain Scale (VAS). Categorical data were presented using simple and absolute frequencies, followed by Pearson's chisquare test (χ²) for the association between the level of pain and the dependent variables. RESULTS: The age of mothers remained between 18 and 35 years old, with a complete level of education, and most of them had no occupational activity. It was observed that, although the study did not show a significant association between postural habits and the level of pain, this symptom was present in 73.5% of women and prevailed in levels from moderate (n=26) to severe (n=24), keeping a discreet relationship with some types of deviations. The most prevalent postural change was lumbar hyperlordosis (69.1%). CONCLUSION: It was possible to see that pain and postural deviations are present in women with babies in arms, and it is necessary to think of interventions with this focus for this group.

Back Pain in Children and Adolescents.

Back pain has long been considered an uncommon complaint in the pediatric population. When present, teaching had been that pediatric back pain almost always has a diagnosable cause, many of which are progressive and potentially debilitating. Recent evidence has suggested that pediatric back pain is not only more common than once thought but also, within certain populations, benign and idiopathic. This, in turn, places an increasing amount of pressure on pediatricians to accurately assess and manage their patients presenting with complaints of back pain. The aim of this article is to serve as a review of the current literature on pediatric back pain. The article reviews the epidemiology, basic anatomy, and important elements of a history and examination, which should be considered when a child presents complaining of back pain. Last, a common differential diagnosis with evaluation and management is also given to help guide pediatricians through their medical decision making.

The Effect of Reduction Mammaplasty on Body Posture: A Preliminary Study.

Excess breast volume can lead to changes in the postural pattern that may result in pain. This causes women to seek reduction mammaplasty, a surgical procedure that reduces breast volume and may provide relief from symptoms. The objective of this study was to evaluate whether reduction mammaplasty can influence the posture of women. The postures of women with breast hypertrophy were evaluated using postural assessment software and photographic recording performed on the day of surgery and 3 months after the procedure. After surgical breast reduction, the patients had statistically significant changes in their postural patterns related to the horizontal alignment of the anterosuperior iliac spines and the angle of the acromion and anterior superior iliac spines. The analysis of the results showed statistically significant data on postural changes in the patients 3 months after the surgical procedure.

Axial Spondyloarthritis after bariatric surgery: a 7-year retrospective analysis.

BACKGROUND: In recent decades, obesity has become a public health problem in many countries. The objective of this study was to evaluate the main joint and extra-articular manifestations related to spondyloarthritis (SpA) after bariatric surgery (BS) in a retrospective cohort. METHODS: Demographic, clinical, laboratory and imaging data from nine patients whose SpA symptoms started after a BS have been described. Modified New York (mNY) criteria for ankylosing spondylitis (AS) and the Assessment of Spondyloarthritis International Society (ASAS) criteria for axial (ax-SpA) and peripheral (p-SpA) spondyloarthritis were applied. RESULTS: The mean weight reduction after BS was 49.3 ± 21.9 kg. The BS techniques were Roux-en-Y gastric bypass (n = 8; 88.9%) and biliopancreatic diversion with duodenal switch (n = 1; 11.1%). Four (44.4%) patients had no axial or peripheral pain complaints before BS, while the other four (44.4%) had sporadic non-inflammatory back pain that had been attributed to obesity. One patient (11.1%) had persistent chronic back pain. In all nine cases, patients reported back pain onset or pattern (intensity or night pain) change after BS (mean time 14.7 ± 18 months). In addition, 8 of them (88.9%) were human leukocyte antigen (HLA)-B27 positive. All nine patients could be classified according to ASAS criteria as ax-SpA and five (55.6%) patients were classified as AS, according to the mNY criteria. CONCLUSION: Our data highlight a temporal link between SpA onset symptoms and the BS, suggesting a possible causal plausibility between the two events.

Contributions of birthweight, annualised weight gain and BMI to back pain in adults: a population-based co-twin control study of 2754 Australian twins.

PURPOSE: To investigate associations between anthropometric measures (birthweight, weight gain and current BMI) and back pain; and to determine whether these associations differ between those born with low or full birthweight. METHODS: The cross-sectional associations between the lifetime prevalence of back pain and anthropometric measures (birthweight, weight gain and current BMI) among 2754 adult twins were investigated in three stages: total sample; within-pair case-control for monozygotic and dizygotic twins together; and within-pair case-control analysis separated by dizygotic and monozygotic. Results were expressed as odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Birthweight was not associated with back pain (OR 0.99; 95% CI 0.99-1.00), but a weak association was found between weight gain (OR 1.01; CI 1.00-1.01) or current BMI (OR 1.02; 95% CI 1.00-1.05) and back pain in the total sample analysis. These associations did not remain significant after adjusting for genetics. The associations did not differ between those whose were born with low or full birthweight. CONCLUSION: Birthweight was not associated with prevalence of back pain in adulthood. Weight gain and current BMI were weakly associated with back pain prevalence in the total sample analysis but did not differ between those born with low or full birthweight. However, the small-magnitude association only just achieved significance and appeared to be confounded by genetics and the early shared environment. Our results suggest that a direct link between these predictors and back pain in adults is unlikely. These slides can be retrieved under Electronic Supplementary Material.

Rare case of adult pancreatic haemangioma and literature review.

Pancreatic haemangiomas are benign vascular tumours very rare in adults. Twenty-two cases are described in the literature. The symptoms are non-specific, and therefore rarely clinically suspected, and the vast majority are incidental findings in imaging tests such as ultrasound, CT, angiography or MRI. They appear on CT as a cystic lesion with contrast enhancement in the arterial phase. We present the case of a 36-year-old male patient with no history of disease, referred with lumbar pain and suspected renal calculus after tomography showing hypervascular enhancement in the pancreatic body and infiltrative lesion (possible neuroendocrine neoplasia) on MRI and biliopancreatic echoendoscopy. He was submitted to laparotomy with subtotal pancreatectomy and splenectomy and satisfactory evolution.

Spinal pleomorphic xanthoastrocytoma: case report and literature review / Xantoastrocitoma pleomórfico espinal: reporte de caso y revisión de la literatura

El Xantoastrocitoma Pleomórfico Espinal (XAPE) es una neoplasia primaria infrecuente del sistema nervioso central, descrita por primer vez en 1979. De estirpe astrocítica y aunque clasificada como grado II por la OMS, pueden existir variantes anaplásicas o malignas. Con localización usualmente temporal, pocos casos espinales se han descrito a la fecha, debido probablemente a un subdiagnóstico o un subregistro. El pronóstico es generalmente bueno y depende en gran medida del tipo histológico y extensión de la resección quirurgica. Describimos el caso de un hombre de 30 años de edad con dorsalgiay paresia del miembro inferior izquierdo. Se encontró en imágenes de resonancia magnética una lesión aparentemente intradural, extraaxial en los segmentos T8-T9 que se llevó a resección. Se confirmó por histopatología la presencia de un XAPE primario. En la presente publicación realizamos una revisión de la literatura disponible.

Spinal Pleomorphic Xanthoastrocytoma (SPXA) is a rare CNS primary neoplasm, first described in 1979. Although of astrocytic lineage and classified as a grade II neoplasm by the WHO, it may be have anaplastic or malignant variants. Usually located in the temporal lobe, few spinal cases have been described to date, probably due to underdiagnosis and underreporting. It usually has a good prognosis, but it depends on its histological type and extent of surgical resection. In this article, we describe the case of a 30-year old male who complained of low back pain and left lower limb paresis. The MRI showed an apparently intradural, extraaxial lesion at T8-T9 segments. The diagnosis of a primary SPXA was confirmed by histopathological studies. In this article, a review of the available literature is presented.
