RESUMO

Introdução: A lombalgia é uma condição prevalente e que apresenta importante impacto na capacidade funcional e na qualidade de vida, sendo a sua correta abordagem na Atenção Primária à Saúde fundamental para a identificação e o estabelecimento de um diagnóstico etiológico precoce de possíveis patologias que possam estar relacionadas a desfechos mórbidos e a graves limitações funcionais. Apresentação do caso: Paciente de 56 anos, sexo masculino, hipertenso, foi encaminhado para serviço especializado de reumatologia com histórico de lombalgia havia mais de 20 anos. Ao exame físico foi constatada presença de deformidades da coluna vertebral e extensa limitação de movimentos. Exames radiográficos mostravam esclerose de articulações sacroilíacas, osteopenia difusa e coluna vertebral em aspecto de "bambu". Conclusões: Constata-se a importância de que na abordagem das lombalgias na atenção primária se busque o reconhecimento de possíveis etiologias graves e potencialmente incapacitantes que possam estar subjacentes à queixa de dor lombar. Com esse objetivo, é fundamental o reconhecimento das chamadas red flags relacionadas às lombalgias, além de sua caracterização como mecânica ou inflamatória. Perante a atuação da atenção primária no oferecimento de um cuidado pautado na integralidade e na prevenção de agravos, reafirma-se a importância de uma avaliação clínica pormenorizada das lombalgias nesse nível de atenção à saúde.

Introduction: Low back pain is a prevalent condition that has an important impact on functional capacity and quality of life, and its correct approach in Primary Care is fundamental to the identification and establishment of an early etiological diagnosis of possible pathologies that may be related to outcomes morbid conditions and serious functional limitations. Case presentation: 56-year-old male patient, hypertensive, referred to a specialized rheumatology service with a history of low back pain for over 20 years. Physical examination revealed the presence of spinal deformities and extensive movement limitations. Radiographic examinations showing sclerosis of the sacro-iliac joints, diffuse osteopenia and a "bamboo" appearance of the spine. Conclusions: It is important that in the approach of low back pain in Primary Care, we seek to recognize possible serious and potentially disabling etiologies that may underlie the complaint of low back pain. For that, it is essential to recognize the so-called "red flags" related to low back pain, in addition to its characterization as mechanical or inflammatory. Given the role of Primary Care in offering care based on integrality and in the prevention of injuries, the importance of a detailed clinical assessment of low back pain at this level of health care is reaffirmed.

RESUMO

OBJECTIVE: To investigate the effects of combining a Pilates program with photobiomodulation therapy (PBMT) in patients with chronic nonspecific low back pain (CNLBP). METHODS: Thirty-eight adults with CNLBP were randomly assigned to two groups: Pilates exercise + active PBMT (PIL + PBMT) or Pilates exercise + sham PBMT (PIL + SHAM). Both groups performed an 8-week mat Pilates program and received PBMT on their lumbar muscles 10 min before and after each session. The following variables were assessed before and after intervention: peak pain intensity, postural balance (i.e., center of the pressure [A-COP], velocity anteroposterior [Vel AP], and velocity mediolateral [Vel ML]), perceived disability (i.e., Oswestry Disability Index [ODI] and Roland Morris Disability Questionnaire [RMDQ]), and pain-related fear of movement (i.e., Tampa Scale of Kinesiophobia [TSK], Fear Avoidance Beliefs Questionnaire [FABQ], and Pain Catastrophizing Scale [PCS]). RESULTS: Postural balance variables showed no statistically significant differences (p > 0.05) across time or between groups. The groups showed similar (p < 0.05) reductions in peak pain intensity, ODI, RMDQ, and PCS scores, but no statistically significant difference (p > 0.05) in TSK and FABQ scores. CONCLUSION: The mat Pilates program reduced peak pain intensity, perceived disability, and pain catastrophizing in adults with CNLBP, but PBMT had no additional effect on these variables. Mat Pilates alone or combined with PBMT was not able to improve postural balance.

RESUMO

Objective: To describe the accuracy of HealthVCF, a software product that uses artificial intelligence, in the detection of incidental moderate-to-severe vertebral compression fractures (VCFs) on chest and abdominal computed tomography scans. Materials and Methods: We included a consecutive sample of 899 chest and abdominal computed tomography scans of patients 51-99 years of age. Scans were retrospectively evaluated by the software and by two specialists in musculoskeletal imaging for the presence of VCFs with vertebral body height loss > 25%. We compared the software analysis with that of a general radiologist, using the evaluation of the two specialists as the reference. Results: The software showed a diagnostic accuracy of 89.6% (95% CI: 87.4-91.5%) for moderate-to-severe VCFs, with a sensitivity of 73.8%, a specificity of 92.7%, and a negative predictive value of 94.8%. Among the 145 positive scans detected by the software, the general radiologist failed to report the fractures in 62 (42.8%), and the algorithm detected additional fractures in 38 of those scans. Conclusion: The software has good accuracy for the detection of moderate-to-severe VCFs, with high specificity, and can increase the opportunistic detection rate of VCFs by radiologists who do not specialize in musculoskeletal imaging.

Objetivo: Descrever a acurácia do software HealthVCF na detecção incidental de fraturas compressivas de corpos vertebrais moderadas a graves em exames de tomografia computadorizada do tórax e abdome. Materiais e Métodos: Foram incluídos 899 exames consecutivos de pacientes com idades entre 51 e 99 anos. As imagens foram retrospectivamente avaliadas pelo software e por dois radiologistas especializados em musculoesquelético que investigaram fraturas compressivas de corpos vertebrais com perda da altura somática > 25%. A análise comparativa foi realizada entre o software e um radiologista geral, usando a avaliação do especialista como referência. Resultados: O software apresentou uma acurácia de 89,6% (IC 95%: 87,4­91,5%) para fraturas compressivas moderadas a graves, com sensibilidade de 73,8%, especificidade de 92,7% e valor preditivo negativo de 94,8%. Entre as 145 tomografias positivas detectadas pelo software, o radiologista geral deixou de relatar as fraturas em 62 (42,8%) e o algoritmo detectou fraturas adicionais em 38 dessas tomografias. Conclusão: O software possui boa acurácia na detecção de fraturas compressivas moderadas a graves, com alta especificidade, podendo aumentar a taxa de detecção oportunística dessas fraturas por radiologistas não especializados em musculoesquelético.

RESUMO

BACKGROUND: Low back pain and neck pain are primary causes of disability, with low back pain being a frequent reason for medical consultations. After conservative and pharmacological treatments, spinal injections are considered the next option. Despite multiple guidelines, spinal blocks remain controversial in terms of indication, technique, and operator, leading to considerable interinstitutional variability. The absence of regional studies in Latin America on how spinal surgeons handle spinal injections prompts the objectives of this study: to evaluate spinal surgeons' knowledge and experience, analyze techniques, and identify barriers and challenges in implementing spinal injections, including resource limitations, technology access, and training. METHODS: A cross-sectional survey was performed using a questionnaire specifically designed by the authors. RESULTS: Two hundred sixty spinal surgeons from Latin America participated and answered a 17-question questionnaire; 75% performed their own spinal blocks and they are willing to keep on learning new techniques on the field. The most frequent block, was the lumbar facet injection (80%). And the great majority (76%) used fluoroscopy in their practice. CONCLUSIONS: The study addresses a critical gap in the literature by focusing on spinal interventions in Latin America, where there is a notable lack of regional studies. The majority of the surgeons enrolled perform their own spinal injections, and they are interested in keep on learning. The findings not only contribute to the global discourse on spinal care but also offer a basis for the development of region-specific guidelines and educational initiatives.

RESUMO

SUMMARY: Conducting morphometric studies including many parameters and establishing certain standards for the anatomy of the lumbar spine will facilitate clinical applications. The Turkish example of lumbar vertebrae and disc morphometry has not yet been presented comprehensively. In our study, abdominal computed tomography images of 700 adults were evaluated retrospectively. It was observed that the anterior height of the vertebral bodies increased from L1 to L4 in males, and from L1 to L5 in females. The posterior height of the vertebral bodies was lowest at L5 in both sexes, while it was highest at L3 in males and L4 in females. In all age groups, the values for males were greater (p0.05). In all age groups and both sexes, an increase in anterior disc heights towards disc 5 was observed. The values for males were greater than those for females (p<0.05). The posterior disc height at disc 5 was higher in females, and in other discs, it was higher in males (p<0.05). In conclusion, it was found that the measurement values of the parameters examined varied according to lumbar level and sex, but were independent of age. The morphometric data we obtained are important in terms of providing a reference for the people of our region and contributing to the literature.

La realización de estudios morfométricos que incluyan diversos parámetros anatómicos y el establecimiento de ciertos estándares para la anatomía de la columna lumbar facilitarán los procedimientos clínicos. Como ejemplo, aún no se ha presentado de manera detallada la morfometría de las vértebras lumbares y del disco intervertebral en individuos turcos. En nuestro estudio evaluamos retrospectivamente imágenes de tomografía computarizada abdominal en 700 individuos adultos de ambos sexos. Observamos que la altura anterior de los cuerpos vertebrales aumentaba de L1 a L4 en los hombres y de L1 a L5 en las mujeres. La altura posterior de los cuerpos vertebrales fue más baja en L5 en ambos sexos, mientras que fue más alta en L3 en hombres y L4 en mujeres. En todos los grupos etarios los valores para los hombres fueron mayores (p0,05). En todos los grupos de edad y en ambos sexos se observó un aumento en la altura anterior del disco intervertebral hacia el disco 5. Los valores de los hombres fueron mayores que los de las mujeres (p<0,05). La altura posterior del disco intervertebral en el disco 5 fue mayor en las mujeres y en otros discos fue mayor en los hombres (p<0,05). En conclusión, se encontró que los valores de medición de los parámetros examinados variaron según el nivel lumbar y el sexo, pero fueron independientes de la edad. Los datos morfométricos que obtuvimos son importantes en términos de proporcionar una referencia para la población de nuestra región y contribuir a la literatura.

RESUMO

INTRODUCTION: The prone transpsoas technique (PTP) is a modification of the traditional lateral lumbar interbody fusion approach, which was first published in the literature in 2020. The technique provides several advantages, such as lordosis correction and redistribution, single-position surgery framework, and ease of performing posterior techniques when needed. However, the prone position also leads to the movement of some retroperitoneal, vascular, and neurological structures, which could impact the complication profile. Therefore, this study aimed to investigate the occurrence of major complications in the practice of early adopters of the PTP approach. METHODS: A questionnaire containing 8 questions was sent to 50 participants and events involving early adopters of the prone transpsoas technique. Of the 50 surgeons, 32 completed the questionnaire, which totaled 1963 cases of PTP surgeries. RESULTS: Nine of the 32 surgeons experienced a major complication (28%), with persistent neurological deficit being the most frequent (7/9). Of the total number of cases, the occurrence of permanent neurological deficits was approximately 0,6%, and the rate of vascular and visceral injuries were both 0,05% (1/1963 for each case). CONCLUSION: Based on the analysis of the questionnaire responses, it can be concluded that PTP is a safe technique with a very low rate of serious complications. However, future studies with a more heterogeneous group of surgeons and a more rigorous linkage between answers and patient data are needed to support the findings of this study.

RESUMO

Introdução: A cefaleia pós punção dural (CPPD) é uma complicação da punção lombar, um procedimento que, apesar de bem tolerado, está sujeito a adversidades, ocorrendo devido a um vazamento persistente do líquido cefalorraquidiano (LCR) do local da punção dural. A incidência de CPPD pode estar relacionada às características dos pacientes e dos procedimentos. Notou-se que em mulheres jovens até 30 anos, o risco de CPPD é maior quando comparado aos homens, não apresentando diferença a partir da quinta década de vida. Objetivo: investigar os diferentes sintomas e efeitos gerados pelos diferentes tipos de agulha, como calibre e modo de inserção, que visem reduzir a CPPD. Métodos: Trata-se de uma revisão sistemática de literatura realizada no período de 2 de agosto a 20 de novembro de 2023 por meio de pesquisas no PubMed. Foram utilizados os descritores: "Post-Dural Puncture Headache" e suas variações do MeSH, sendo submetidos aos critérios de inclusão: estudos em humanos, nos últimos 10 anos, ensaios clínicos e ensaios clínicos controlados e randomizados. Para garantir a qualidade da revisão sistemática foi aplicada a lista de verificação PRISMA de 2020. Resultados: Após investigação estatística, observou-se que as agulhas 25W e 25S demandaram maior tempo médio para a coleta de LCR (15 e 7 min, respectivamente). Ao se comparar 25W com 20Q (3 min), 22S (5 min) e 25S quanto à esta variável, observouse diferença significativa em todas as comparações. Conclusão: As agulhas do tipo atraumática foram associadas com redução do risco de desenvolvimento de CPPD quando comparadas às convencionais. Foi constatado que, dentre as agulhas convencionais, a traumática de 25G é melhor para a prevenção de CPPD que a de 22G.

Introduction: Post-Dural Puncture Headache (PDPH) is a complication of lumbar puncture, a procedure that, despite being well-tolerated, is subject to adversities, occurring due to a persistent leakage of cerebrospinal fluid (CSF) from the site of dural puncture. The incidence of PDPH may be related to patient and procedural characteristics. It has been noted that in young women up to 30 years old, the risk of CPPD is higher compared to men, with no difference between sexes from the fifth decade of life onward. Objective: To investigate the different symptoms and effects generated by different types of needles, such as gauge and insertion method, aiming to reduce CPPD. Methods: Is a systematic literature review conducted from August to October 2023 through searches on PubMed. The descriptors "Post-Dural Puncture Headache" and its MeSH variations were used. A total of 1,839 articles were found, which were then subjected to inclusion criteria: studies conducted in the last 10 years, controlled trials, and randomized clinical trials. Results: After statistical investigation, it was observed that the 25W and 25S needles required a longer average time for cerebrospinal fluid collection (15 and 7 minutes, respectively). When comparing 25W with 20Q (3 minutes), 22S (5 minutes), and 25S regarding this variable, a significant difference was observed in all comparisons. Conclusion: Atraumatic needles were associated with a reduction in the risk of developing CPPD compared to conventional needles. It was found that among conventional needles, the traumatic 25G needle is better for preventing CPPD than the 22G needle.

RESUMO

BACKGROUND: Degenerative lumbar spine disease is the leading cause of disability and work absenteeism worldwide. Lumbar microdiscectomy became the standard treatment for herniated discs and stenotic disease. With the evolution of different techniques, endoscopic spinal surgery emerged to minimize the surgical footprint while providing at least non-inferior results. Currently, two different types of endoscopic spine procedures are dominating the surgical scenario: "Full-Endoscopic" (FE) and Unilateral Biportal Endoscopic" (UBE) Spine Surgery. The aim of this study is to describe and analyze their indications, their technical characteristicswithitsadvantagesanddisadvantagesofbothtechniquesandtheirfuture trends. METHODS: We performed a narrative review of the most relevant articles published up to August 2023 through a Pub Med search. The search terms " FE Spine Surgery" and " UBE Spine Surgery" were used. The articles selected, were independently reviewed by 3 authors and 55 full text articles were reviewed. RESULTS: The FE and UBE Spine Surgery techniques were described. The FE technique is performed with a monoportal access under constant saline irrigation. The FE comprises the transforaminal and the interlaminar approaches, and the indication depends from the pathology to treat, and still remains controversial. UBE can approach also the spine from a posterior, postero lateral,and para spinal route. It uses two different ports addressed to a target with continuous irrigation. The process of establishing these two portals is called triangulation. CONCLUSIONS: FE and UBE spine surgery have demonstrated outcomes comparable to open surgery, minimizing complications and surgical footprint.

RESUMO

BACKGROUND: The SpineST-01 system is an image-guided vertebrae cannulation training system. During task execution, the computer calculates performance-based metrics displaying different visual perspectives (lateral view, axial view, anteroposterior view) with the position of the instrument inside the vertebra. Finally, a report with the metrics is generated as performance feedback. METHODS: A training box holds a 3D printed spine section. The computer works with 2 orthogonally disposed cameras, tracking passive markers placed on the instrument. Eight metrics were proposed to evaluate the execution of the surgical task. A preliminary study with 25 participants divided into 3 groups (12 novices, 10 intermediates, and 3 expert) was conducted to determine the feasibility of the system and to evaluate and assess the performance differences of each group using Kruskal-Wallis analysis and Mann-Whitney U analysis. In both analyses, a P value ≤ 0.05 was considered statistically significant. RESULTS: When comparing experts versus novices and all 3 groups, statistical analysis showed significant differences in 6 of the 8 metrics: axial angle error (°), lateral angle error (°), average speed (mm/second), progress between shots (mm), Time (seconds), and shots. The metrics that did not show any statistically significant difference were time between shots (seconds), and speed between shots (mm/second). Also, the average result comparison placed the experts as the best performance group. CONCLUSIONS: Initial testing of the SpineST-01 demonstrated potential for the system to practice image-guided cannulation tasks on lumbar vertebrae. Results showed objective differences between experts, intermediates, and novices in the proposed metrics, making this system a feasible option for developing basic navigation system skills without the risk of radiation exposure and objectively evaluating task performance.

RESUMO

INTRODUCTION: surgical site infections (SSI) remain a significant cause of morbidity and mortality and one of the most representative causes of nosocomial infections. The use of intrawound vancomycin in lumbar spine surgery is a potential prophylactic measure against SSI; however, evidence regarding its efficacy is contradictory. Our study was designed to research if intrawound vancomycin significantly prevents SSI in lumbar spine surgery. MATERIAL AND METHODS: this is a randomized, double-blinded, controlled clinical trial; 233 patients who underwent lumbar spine surgery, were randomly assigned to a group in which intrawound vancomycin was instilled in the incision before closure (109), or to a control group (114). The main outcome is the presence of SSI; we determined its prevalence and searched for difference between groups for association between SSI and independent variables. RESULTS: global SSI prevalence was 1.8%, in the experimental group was 0.9%, in the control group was 2.6%. There was no significant difference between these values, p = 0.622. The relative risk of SSI in the experimental group was 0.35 (95% CI 0.037-3.30), that of the control group was 2.87 (95% CI 0.30-27.16). The number needed to treat is 58.3. We did not find a significant association between the independent variables studied and the appearance of SSI. CONCLUSIONS: we did not find a significant difference in the prevalence of SSI between groups nor a significant association between SSI and independent variables.

INTRODUCCIÓN: las infecciones postoperatorias del sitio quirúrgico son una importante causa de morbimortalidad y una de las formas más comunes de infecciones nosocomiales. La aplicación de vancomicina al terminar una intervención de columna lumbar es una potencial práctica profiláctica de infecciones del sitio quirúrgico (ISQ). La evidencia que sostiene su uso es controversial. Nuestro estudio investiga si la aplicación de vancomicina disminuye en forma significativa la prevalencia de ISQ. MATERIAL Y MÉTODOS: ensayo clínico aleatorizado, controlado, cegado; 223 pacientes intervenidos de la columna lumbar fueron aleatoriamente asignados a un grupo experimental de 109 pacientes en quienes se colocó vancomicina y a un grupo control de 114 pacientes que no recibió vancomicina. El principal desenlace del estudio es la aparición de ISQ; se estudió la prevalencia de ISQ en ambos grupos y se buscó si existe diferencia significativa. Se analizó la existencia de factores predictores de ISQ. RESULTADOS: la prevalencia global de infección fue 1.8%; en el grupo experimenta 0.09% y en el grupo control 2.6%. No hubo diferencia significativa entre estas cifras, p = 0.622. El riesgo relativo de ISQ en el grupo experimental fue 0.35 (IC95% 0.037-3.30), el del grupo control fue 2.87 (IC95% 0.30-27.16). El número necesario para tratar es 58.3. No encontramos asociación significativa entre las variables independientes estudiadas y la aparición de ISQ. CONCLUSIONES: no encontramos evidencia suficiente de que la aplicación de vancomicina disminuya significativamente la prevalencia de ISQ ni asociación significativa de ISQ con las variables independientes estudiadas.

RESUMO

BACKGROUND: Lumbar foraminal stenosis is a common cause of chronic lower back pain and radiculopathy often treated by epidural steroid injections. In the absence of imaging findings with a positive physical exam demonstrating symptoms, percutaneous neuroplasty (PNP) may be an alternative to transforaminal epidural steroid injections that have otherwise failed. CASE PRESENTATION: We present two cases (55-year-old man and 65-year-old woman) with chronic low back pain and radiculopathy with otherwise normal imaging demonstrating no lumbar foraminal stenosis refractory to transforaminal epidural steroid injections. PNP was performed using reference spinal needles with both patients achieving sustained > 50-75% pain relief. CONCLUSION: PNP offers interventional chronic pain physicians and patients with refractory chronic low back pain with lumbar radiculopathy due to fibrosis an alternative, safe treatment that offers sustained results. Furthermore, this is the first of its kind to offer a step-by-step procedural step of PNP using a reference spinal needle.

RESUMO

OBJECTIVE: To evaluate the clinical-surgical results of the tubular vs. mini-open approach in lumbar discoidectomy. The tubular approach promises to reduce the number of rest days and an earlier return to daily activities and work. METHOD: A case-control study of patients operated on for disc herniation using tubular surgery (case) and mini-open (control) was carried out. The variables investigated were as follow: radicular and lumbar pain, sex, age, failure in conservative treatment, single-level lumbar hernia, surgical time, bleeding, length of hospital stay, persistence of symptoms, complications, occupational activity, and reintegration into everyday activities. RESULTS: Through 100 surgeries performed, two groups were created, tubular and mini-open, with 50 patients each, with L4-L5 or L5-S1 disc herniation, respectively. The most affected level was L4-L5 (69%). Of the total cases, a significant improvement was found (p < 0.05) at 15 postoperative days in the VAS and ODI scale in the tubular group with respect to mini-open. Complications such as surgical wound infection, durotomy, and persistent pain occurred. CONCLUSIONS: The tubular approach is a safe and effective option for herniated discs of the lumbar segment, and reduces surgical times, bleeding, and the time of reinsertion to daily activities of the patient.

OBJETIVO: Evaluar los resultados clínico-quirúrgicos del abordaje tipo tubular en comparación con el mini-open en la discoidectomía lumbar. El abordaje tubular promete reducir el número de días de reposo y una reincorporación más temprana a las actividades diarias y laborales. MÉTODO: Se realizó un estudio de casos y controles de pacientes operados por hernia discal mediante cirugía tubular (casos) o mini-open (controles). Las variables investigadas fueron: dolor radicular y lumbar, sexo, edad, falla en el tratamiento conservador, hernia lumbar de un solo nivel, tiempo quirúrgico, sangrado, tiempo de estancia hospitalaria, persistencia de síntomas, complicaciones, tipo de actividad ocupacional y reinserción a las actividades cotidianas. RESULTADOS: Se realizaron 100 cirugías y se crearon dos grupos, tubular y mini-open, con 50 pacientes cada uno, con hernia discal de L4-L5 o L5-S1, respectivamente. El nivel más afectado fue L4-L5 (69%). Del total de los casos, se encontró mejoría significativa (p < 0.05) a los 15 días posquirúrgicos en la escala EVA y ODI en el grupo tubular con respecto al mini-open. Ocurrieron complicaciones como infección de herida quirúrgica, durotomía y dolor persistente. CONCLUSIONES: El abordaje tubular es una opción segura y efectiva para hernias discales del segmento lumbar, y reduce los tiempos quirúrgicos, el sangrado y el tiempo de reinserción a las actividades cotidianas del paciente.

RESUMO

BACKGROUND: The static sitting position contributes to increased pressure on the lumbar intervertebral disc, which can lead to dehydration and decreased disc height. OBJECTIVE: To systematically investigate the of sitting posture on degeneration of the lumbar intervertebral disc. MATERIALS AND METHODS: One researcher carried out a systematic literature search of articles with no language or time limits. Studies from 2006 to 2018 were found. The searches in all databases were carried out on January 28, 2022, using the following databases: Pubmed, Scopus, Embase, Cochrane, and Physiotherapy Evidence Database (PEDro) databases, and for the grey literature: Google scholar, CAPES Thesis and Dissertation Bank, and Open Grey. The acronym PECOS was used to formulate the question focus of this study: P (population) - male and female subjects; E (exposure) - sitting posture; C (comparison) - other posture or sitting posture in different periods; O (outcomes) - height and degeneration of the lumbar intervertebral disc(s), imaging exam; and S (study) - cross-sectional and case control. RESULTS: The risk of bias was in its moderate totality in its outcome: height and degeneration of the lumbar intervertebral disc(s) - imaging. Of the four selected studies, three found a decrease in the height of the disc(s) in sitting posture. CONCLUSION: The individual data from the manuscripts suggest that the sitting posture causes a reduction in the height of the lumbar intervertebral disc. It was also concluded that there is a need for new primary studies with a more in-depth design and sample size.

RESUMO

Cerebrospinal fluid opening pressure values are associated with various neurologic diseases; however, numerous factors can modify this measurement. This study aims to describe factors related to modifications in opening pressure measurements in pediatric patients. Methods: A retrospective analysis of lumbar punctures in pediatric patients conducted by the neuropediatrics group with institutional standardization. Bivariate and linear regression analyses were performed to determine the association between opening pressure and variables included in the study. Results: 544 events, median age 107 months, median opening pressure 19.7 cm H2O. Bivariate analysis found no association with medication use; anesthetics that increased opening pressure were remifentanil (P = .02) and propofol (P = .05), along with a positive linear correlation between opening pressure and age (P < .0001). Multiple linear regression analysis revealed that age, BMI, male gender, and remifentanil use were associated with an increase in opening pressure, whereas corticosteroid withdrawal was associated with a reduction in opening pressure. There is an interaction between age and headache, with an association with increased opening pressure up to around 140 months. Conclusion: This study identifies factors associated with changes in opening pressure, crucial for estimating normal opening pressure values in children. Headaches, anesthetic use, and corticosteroid withdrawal are confirmed as significant factors.

RESUMO

RESUMEN El caso es de una mujer de 46 años con pielonefritis aguda izquierda y duplicidad ureteral bilateral. La pielonefritis aguda es una infección grave del tracto urinario que puede variar en su presentación clínica, desde síntomas leves hasta sepsis. El dolor lumbar es un síntoma común en la pielonefritis aguda, y puede presentarse de forma unilateral o bilateral. La duplicidad ureteral es una anomalía congénita que resulta en uréteres que transportan la orina desde el mismo riñón hasta la vejiga, y puede causar complicaciones como reflujo vesicoureteral y obstrucción ureteral. El tratamiento incluyó antibióticos y control ambulatorio en consulta de Urología. El caso destaca la importancia de un enfoque diagnóstico meticuloso y la consideración de anomalías congénitas subyacentes que pueden complicar el cuadro clínico y el tratamiento. La integración de hallazgos clínicos, análisis de laboratorio y pruebas de imagen fue fundamental para el diagnóstico preciso y el plan de tratamiento adecuado.

ABSTRACT The case presents a 46-year-old woman with left acute pyelonephritis and bilateral duplicated ureters. Acute pyelonephritis is a severe urinary tract infection that can vary in clinical presentation, from mild symptoms to sepsis. Lower back pain is a common symptom and can be unilateral or bilateral. Duplicated ureters are a congenital anomaly resulting in the transport of urine from the same kidney to the bladder, and can cause complications such as vesicoureteral reflux and ureteral obstruction. Treatment involved antibiotics and outpatient urology follow-up. The case underscores the importance of a meticulous diagnostic approach and consideration of underlying congenital anomalies that can complicate clinical management and treatment. The integration of clinical findings and complementary tests was essential for an accurate diagnosis and appropriate treatment plan.

RESUMO

OBJECTIVE: Determine if herniation morphology based on the Michigan State University Classification is associated with differences in (1) patient-reported outcome measures (or (2) surgical outcomes after a microdiscectomy. METHODS: Adult patients undergoing single-level microdiscectomy between 2014 and 2021 were identified. Demographics and surgical characteristics were collected through a query search and manual chart review. The Michigan State University classification, which assesses disc herniation laterality (zone A was central, zone B/C was lateral) and degree of extrusion into the central canal (grade 1 was up to 50% of the distance to the intra-facet line, grade >1 was beyond this line), was identified on preoperative MRIs. patient-reported outcome measures were collected at preoperative, 3-month, and 1-year postoperative time points. RESULTS: Of 233 patients, 84 had zone A versus 149 zone B/C herniations while 76 had grade 1 disc extrusion and 157 had >1 grade. There was no difference in surgical outcomes between groups (P > 0.05). Patients with extrusion grade >1 were found to have lower Physical Component Score at baseline. On bivariate and multivariable logistic regression analysis, extrusion grade >1 was a significant independent predictor of greater improvement in Physical Component Score at three months (estimate = 7.957; CI: 4.443-11.471, P < 0.001), but not at 1 year. CONCLUSIONS: Although all patients were found to improve after microdiscectomy, patients with disc herniations extending further posteriorly reported lower preoperative physical function but experienced significantly greater improvement three months after surgery. However, improvement in Visual Analog Scale Leg and back, ODI, and MCS at three and twelve months was unrelated to laterality or depth of disc herniation.

RESUMO

Introduction: Simultaneous spinal stenosis in three regions of the spine is an unusual condition that demands proper clinical evaluation and imaging. Currently, there are no established guidelines for its diagnostic and therapeutic approach. Objective: The objective of this study is to describe, based on a case report, the clinical presentation, treatment, and patient progression concerning triple stenosis, contrasting it with available evidence through a narrative review of the literature. Case Presentation: A 69-year-old woman presented with a progressive paraparesis accompanied by right sciatica and positive signs of upper motor neuron involvement. Imaging confirmed triple stenosis: cervical, dorsal, and lumbar. Dorsal decompression and tumor resection were performed in association with conservative treatment for cervical and lumbar stenosis, resulting in a favorable evolution one year post-surgery. Conclusion: Symptomatic triple-region spinal stenosis is an unusual condition. Proper clinical and radiological assessments will enable accurate diagnosis and timely management.

Introducción: La estenosis espinal de las tres regiones de la columna en simultáneo es una entidad infrecuente, que requiere una adecuada valoración clínica e imagenológica. Actualmente no existen guías establecidas para su abordaje diagnóstico y terapéutico. Objetivo: El objetivo de este trabajo es describir, partiendo del reporte de un caso, la presentación clínica, el tratamiento y la evolución en un paciente con triple estenosis y contrastarlo con la evidencia disponible a través de una revisión narrativa de la literatura. Presentación del caso: Mujer de 69 años de edad que consultó con un cuadro de paraparesia progresiva asociado a ciatalgia derecha y signos de motoneurona superior positivos. Imagenologicamente se constató una triple estenosis: cervical, dorsal y lumbar, realizándose una descompresión y resección tumoral dorsal asociado al tratamiento conservador de las estenosis cervical y lumbar, con una evolución favorable al año postquirúrgico. Conclusión: La estenosis espinal de triple región sintomática es una condición rara, las valoraciones clínicas y radiológicas adecuadas permitirán un diagnóstico correcto con un abordaje adecuado y oportuno.

RESUMO

OBJECTIVE: This study aims to compare the effects of microscopic microdiscectomy and microendoscopic discectomy on pain, disability, fear of falling, kinesiophobia, anxiety, quality of life in patients with lumbar disc herniation (LDH). METHODS: A total of 90 patients who underwent microscopic microdiscectomy (n = 40) and microendoscopic discectomy (n = 50) for LDH were included in this study. The patients' pain, disability, fear of falling, kinesiophobia, anxiety, and quality of life were evaluated before the surgery, in the early postoperative period and three months after. RESULTS: In patients who underwent microendoscopic discectomy, the results of pain, disability, fear of falling, kinesiophobia and anxiety were statistically decreased compared with the microscopic microdiscectomy in the early postoperative period and three months later (p < 0.05). Also, a statistically higher increase was observed in the general health perception of patients who underwent microendoscopic discectomy three months after the operation (p < 0.01). CONCLUSION: Microendoscopic microdiscectomy, remains the most effective and widely applied method with advantages on pain, quality of life, and improved physical functions.

OBJETIVO: Este estudio tiene como objetivo comparar los efectos de la microdiscectomía microscópica y la discectomía microendoscópica sobre el dolor, la discapacidad, el miedo a caer, la kinesiofobia, la ansiedad y la calidad de vida en pacientes con hernia de disco lumbar (LDH). MÉTODOS: Se incluyeron en este estudio un total de 90 pacientes sometidos a microdiscectomía microscópica (n = 40) y discectomía microendoscópica (n = 50) por LDH. Se evaluó el dolor, la discapacidad, el miedo a caer, la kinesiofobia, la ansiedad y la calidad de vida de los pacientes antes de la cirugía, en el postoperatorio temprano y tres meses después. RESULTADOS: En los pacientes sometidos a discectomía microendoscópica, los resultados de dolor, discapacidad, miedo a caer, kinesiofobia y ansiedad disminuyeron estadísticamente en comparación con la microdiscectomía microscópica en el postoperatorio temprano y tres meses después (p < 0.05). Además, se observó un aumento estadísticamente mayor en la percepción de salud general de los pacientes sometidos a discectomía microendoscópica tres meses después de la operación (p < 0.01). CONCLUSIÓN: La microdiscectomía microendoscópica sigue siendo el método más eficaz y ampliamente aplicado con ventajas sobre el dolor, la calidad de vida y la mejora de las funciones físicas.

RESUMO

OBJECTIVE: Obesity is a global epidemic affecting developing countries. The relationship between obesity and perioperative outcomes during elective lumbar spine surgery remains controversial, especially in those without morbid disease. MATERIALS AND METHODS: We retrospectively revised the medical records of patients with lumbar spine degeneration subjected to elective surgery. The data retrieved included demographic and clinical characteristics, body mass index (BMI), obesity status (BMI ≥ 30), surgical interventions, estimated blood loss (EBL), operative time, length of stay (LOS), and post-operative complications. Perioperative outcomes were compared between Grade I-II obese and non-obese individuals. RESULTS: We enrolled 53 patients, 18 with Grade I-II obesity. Their median age was 51, with no differences in gender, comorbidities, laboratory parameters, and surgical procedures received between groups. No clinically relevant differences were found between grade I-II obese and non-obese participants in EBL (300 mL vs. 250 mL, p = 0.069), operative time (3.2 h vs. 3.0 h, p = 0.037), and LOS (6 days vs. 5 days, p = 0.3). Furthermore, BMI was not associated with the incidence of significant bleeding and long stay but showed a modest correlation with operative time. CONCLUSION: Grade I-II obesity does not increase surgical complexity nor perioperative complications during open lumbar spine surgery.

OBJETIVO: La obesidad es una epidemia mundial que afecta a países subdesarrollados. Su relación con los resultados de la cirugía de columna lumbar electiva sigue siendo controvertida, especialmente en obesos sin enfermedad mórbida. MÉTODOS: Se revisaron los expedientes de pacientes con degeneración de la columna lumbar sometidos a cirugía. Los datos recuperados incluyeron características demográficas y clínicas, índice de masa corporal (IMC), estado de obesidad (IMC > 30), intervenciones quirúrgicas, sangrado estimado, tiempo operatorio, tiempo de estancia y complicaciones. Los resultados se compararon entre individuos obesos grado I-II y controles. RESULTADOS: Se incluyeron 53 pacientes, 18 con obesidad de grado I-II. La edad media fue de 51 años, sin diferencias en el sexo, las comorbilidades, los parámetros de laboratorio y los procedimientos quirúrgicos recibidos entre grupos. No se encontraron diferencias relevantes entre los participantes obesos y los no obesos en sangrado (300 vs. 250 mL, p = 0.069), tiempo operatorio (3.2 vs. 3.0 horas, p = 0.037) y estancia (6 vs. 5 días, p = 0.3). El IMC no se asoció con hemorragia y larga estancia, pero mostró una correlación modesta con el tiempo operatorio. CONCLUSIONES: La obesidad grado I-II no predispone a complicaciones durante la cirugía de columna lumbar.

RESUMO

The purpose of this systematic review is to evaluate the safety of pre-endovascular abdominal aortic aneurysm repair (EVAR) embolization of aortic side branches - the inferior mesenteric artery and lumbar arteries. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. A search of MEDLINE and DIMENSION databases identified 9 studies published from 2011 to 2021 that satisfied the inclusion and exclusion criteria. These studies were analyzed to detect the incidence of embolization-related complications. A total of 482 patients underwent preoperative aortic side branch embolization, 30 (6.2%) of whom suffered some kind of minor complication. The only major complication observed was ischemic colitis in 4 (0.82%) patients, two (0.41%) of whom died after bowel resection surgery. Regarding these findings, aortic side branch embolization seems to be a safe procedure, with very low percentages of both minor and major complications.

O objetivo desta revisão sistemática foi avaliar a segurança da embolização de artéria mesentérica inferior (AMI) e artérias lombares (ALs) pré-correção endovascular de aneurisma da aorta abdominal. Foram realizadas pesquisas nas bases de dados MEDLINE e Dimensions. Foram encontrados 9 estudos publicados de 2011 a 2021 que atendiam aos critérios de inclusão e exclusão. Os estudos foram analisados ​​para definir a incidência de complicações relacionadas à embolização. No total, 482 pacientes foram submetidos a embolização de AMI e/ou ALs, dos quais 30 (6,2%) sofreram algum tipo de complicação menor. A única complicação importante observada foi colite isquêmica em 4 (0,82%) pacientes. Dois (0,41%) desses pacientes morreram após cirurgia de ressecção intestinal. Em relação a esses achados, a embolização de AMI e ALs parece ser um procedimento seguro, com um percentual muito baixo de complicações menores e importantes.
