Effectiveness of Epidural Steroid Injection Depending on Discoradicular Contact: A Prospective Randomized Trial.

Lumbar radicular pain is a major public health and economic problem. It is among the most common reasons for professional disability. The most common cause of lumbar radicular pain is intervertebral disc herniation, which results from degenerative disc changes. The dominant pain mechanisms are direct pressure of the hernia on the nerve root and the local inflammatory process triggered by intervertebral disc herniation. Treatment of lumbar radicular pain includes conservative, minimally invasive, and surgical treatment. The number of minimally invasive procedures is constantly increasing, and among these methods is epidural administration of steroids and local anesthetic through a transforaminal approach (ESI TF). The aim of this research was to examine the effectiveness of ESI TF as measured by a visual analog scale (VAS) and the Oswestry Disability Index (ODI), depending on whether there is contact between the herniated intervertebral disc and the nerve root. In both groups of participants, there was a significant reduction in pain intensity, but there was no significant difference between the groups. In the group with disc herniation and nerve root contact, the only significant reduction was in pain intensity (p < 0.001). There were no significant differences in measurements in other domains of the ODI. In the group without disc herniation and nerve contact, there was a significant difference in all domains except weight lifting. In the group without contact, there was significant improvement after 1 month (p = 0.001) and 3 months (p < 0.001) according to the ODI, while there was no significant improvement in the group with contact. In addition, there were no significant differences in the distribution of participants based on the ODI and whether disc herniation and nerve contact was present. The results suggest that transforaminal epidural administration of steroids is a clinically effective method for treating lumbar radicular pain caused by intervertebral disc herniation in people with and without nerve root contact, without significant differences.

TRACHEOBRONCHIAL MORPHOMETRY CORRELATES WITH DEMOGRAPHIC CHARACTERISTICS AND INFECTIONS IN CRITICALLY ILL PATIENTS.

Tracheal measurements in the intensive care unit (ICU) are important for the choice of endotracheal tube and may correlate with patient demographic characteristics and infections. The study included 42 surgical patients, age 60 [48-71] years, who underwent diagnostic chest computed tomography (CT) scans during treatment in the ICU, Osijek University Hospital, in 2019 and 2020. CT scans were analyzed using AW Server 3.2. Measurement analysis showed that the diameters of the tracheobronchial tree, the length of the trachea and left main bronchus were significantly larger in men compared to women (p<0.05 all). The smallest tracheal upper diameter was 15.25 [IQR 11.8-18.8] mm vs. 17.95 [13.55-20.05] mm in septic and nonseptic patients, respectively (p=0.028). A total of 26 patients who underwent CT scans developed nosocomial pneumonia. It was right-sided in 15, left-sided in 6 and bilateral in 5 patients, and correlated significantly with the left main bronchus length (ρ=0.515, p=0.007). No correlation was observed between tracheobronchial measurements and length of ICU treatment, number of hours spent on mechanical ventilation, or survival. A larger study could provide better data on the importance of tracheobronchial tree measurements in ICU patients.

Influence of the Cognitive and Emotional Status of Patients with Chronic Pain on Treatment Success (Reduction in Pain Intensity and Adherence to Pharmacotherapy): A Prospective Study.

This prospective study aimed to determine the cognitive and emotional status among patients with chronic pain and to examine the potential influence on the treatment success, measured by the reduction in pain intensity and adherence to pharmacotherapy. A total of seventy patients were followed for two months. The results of the comparison between patients who did and did not follow the physician's instructions regarding adherence to pharmacotherapy showed a significant difference in cognitive status and a reduction in pain intensity. Patients who followed the physician's instructions on taking analgesics had significantly higher scores on the Montreal Cognitive Assessment (MoCA) of cognitive status and a substantially higher reduction in pain intensity. Scores on the MoCA test provide statistically significant indications regarding patients' decision to follow instructions regarding adherence to pharmacotherapy. Scores on the MoCA test, anxiety, age, and pain intensity (measured with a numeric rating scale­NRS) on admission were identified as potential predictors for the reduction in pain intensity. The linear regression model was statistically significant (χ2 = 40.0, p < 0.001), explained between 43.5% and 61.1% of variance regarding the reduction in pain intensity. The findings of this study show that cognitive status, measured with MoCA, and emotional status, measured with the Depression, Anxiety, and Stress Scale (DASS-21), significantly influence the reduction in pain intensity and adherence to pharmacotherapy. The results suggest that cognitive and emotional status may be potential predictors of treatment success. This finding points to the importance of a biopsychosocial approach in the treatment of chronic pain, where an important emphasis can be placed on the psychosocial determinants of pain.

Quality of Life and Mental Distress in Patients with Chronic Low Back Pain: A Cross-Sectional Study.

The aim of this study was to examine the levels of health-related quality of life (HRQoL), pain intensity, and mental distress in participants with chronic low back pain (CLBP), and to examine the differences in the HRQoL of participants with respect to mental distress and the correlations of the examined variables. Data were collected from 148 patients using the SF-36 Health Status Questionnaire (SF-36), the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) questionnaire, and the visual-analog pain scale (VAS). The results indicate poorer self-assessment of physical health (Me = 28.1) compared to mental health (Me = 39.4). Participants with higher levels of mental distress reported significant emotional limitations (p = 0.003), lower energy (p < 0.001), poorer psychological health (p < 0.001) and social functioning (p < 0.001), more pain (p = 0.007), and, ultimately, poorer general health (p < 0.001). The level of mental distress was related to the level of HRQoL, while a correlation with the level of pain of the participants was not found. The study results indicate a connection between the presence of mental distress and almost all aspects of HRQoL in participants with CLBP.

TREATMENT OPTIONS FOR TRIGEMINAL NEURALGIA.

Trigeminal neuralgia causes severe to excruciating pain that often cannot be successfully reduced with current forms of treatment. The International Association for the Study of Pain (IASP) defines trigeminal neuralgia as a sudden, usually unilateral, powerful, short, stabbing, recurrent episode of pain in the distribution of one or more branches of the trigeminal nerve. Trigeminal neuralgia can be caused by vascular compression of the trigeminal nerve or a tumor process. Pressure on the nerve itself causes nerve demyelination, which is the cause of abnormal depolarization, resulting in the development of ectopic impulses. Pain can be provoked by brushing teeth, shaving, eating, cold, heat, etc. After diagnosing trigeminal neuralgia, magnetic resonance imaging should be performed to rule out multiple sclerosis, a tumor process that can secondarily cause trigeminal neuralgia. The drug of choice for treating trigeminal neuralgia is still carbamazepine. If pharmacological treatment fails, invasive surgical microvascular decompression, stereotactic radiation therapy (gamma knife), percutaneous balloon micro compression, percutaneous glycerol rhizolysis, and percutaneous radiofrequency (RF) may be used.

SATISFACTION OF PARTURIENTS WITH EPIDURAL ANALGESIA DURING DELIVERY: ANALYSIS OF QUESTIONNAIRE AT A SINGLE HOSPITAL CENTER.

Epidural analgesia is one of the most common methods of relieving labor pain. The objective of this study was to examine the effectiveness of epidural analgesia, maternal satisfaction and relationship between the effectiveness of epidural analgesia and various factors. Data were analyzed retrospectively and collected during 2022. A total of 60 parturients participated in the study. Data were collected through a questionnaire before the parturient was discharged from the hospital. The mean assessment of pain on a 1-10 numeric rating scale before epidural analgesia was 7.7 and 3.4 after administration of epidural analgesia. The median assessment of pain before epidural analgesia was 8 (7¬¬-8), and the median assessment of pain after epidural analgesia was 3 (2-5). The average satisfaction with epidural analgesia on a 1-10 scale was 8.11, and the median satisfaction was 10 (7-10). Total of 35 (58.3%) parturients rated satisfaction with 10. Statistically significant association between the effectiveness of epidural analgesia and parity, dilution of administered levobupivacaine, fentanyl administration, and level of education was not found. Childbirth pain is significantly alleviated by the application of epidural analgesia and the satisfaction of parturients is very high.

Changes in dietary habits of patients with chronic pain represent contributing factors to decreased pain intensity and improved quality of life. Pilot study from Croatia.

INTRODUCTION: Objectives: to assess the effectiveness of specifically designed nutrition education for the management of chronic pain and whether any change in dietary habits contribute to decrease in pain intensity. Objectives and methods: 40 patients were enrolled in the 4-week interventional observational study. Patients filled-in questionaires regarding their basic characteristics, pain intensity, quality of life, and dietary habits at baseline and post-intervention. Intervention consisted of 1 individual and 2 group counselings based on the nutrition education specifically designed for the chronic pain management. Results: post-intervention, pain intensity decreased in 67.5 % of patients while significantly improving quality of life (from 42.9 ± 31.3 to 70.1 ± 26.2 points, p = 0.015). All patients responded to nutrition education by increasing the number of meals per day (p < 0.001), improving regularity of breakfast (p = 0.005) and by less frequently skipping meals (p = 0.027). Fewer meal skipping (OR = 0.037, 95 % CI (0.003-0.482), p = 0.012) and lower consumption of foods with negative effect on chronic pain (OR = 0.008, 95 % CI (0.000-0.444), p = 0.019) were found to modestly, but independently contribute to decrease in pain intensity. Still, patients with higher BMI and several diagnoses had low resonse. Conclusions: the developed nutrition education is fit for the management of chronic pain. The main benefits are improved meal consumption pattern along with reduced consumption of foods with pro-inflammatory effect and food cravings. The complexity of chronic pain is obvious in low responsiveness among patients with higher BMI and several conditions.

INTRODUCCIÓN: Introducción: el dolor crónico es una entidad compleja con una inmensa carga individual y social. Objetivo: verificar si la educación nutricional diseñada específicamente para el tratamiento del dolor crónico y si algún cambio en los hábitos alimenticios contribuyen a disminuir la intensidad del dolor. Material y métodos: se incluyeron 40 pacientes en el estudio observacional intervencionista de 4 semanas. Los pacientes completaron cuestionarios sobre las características básicas: la intensidad del dolor, la calidad de vida y los hábitos alimenticios al inicio y después de la intervención. La intervención consistió en 1 asesoramiento individual y 2 grupales basados en la educación nutricional diseñada específicamente para el tratamiento del dolor crónico. Resultados: después de la intervención, la intensidad del dolor disminuyó en el 67,5 % de los pacientes al tiempo que mejoró significativamente la calidad de vida (de 42,9 ± 31,3 a 70,1 ± 26,2 puntos, p = 0,015). Todos los pacientes respondieron a la educación nutricional: aumentaron el número de comidas por día (p < 0,001), mejoraron la regularidad del desayuno (p = 0,005) y omitieron las comidas con menos frecuencia (p = 0,027). Menos saltos de comida (OR = 0,037, IC 95 % [0,003-0.482], p = 0,012) y menor consumo de alimentos con efecto negativo sobre el dolor crónico (OR = 0,008, IC 95 % [0,000-0,444], p = 0.019) se encontraron que modestamente, pero, de formma independiente, contribuyen a disminuir la intensidad del dolor. Sin embargo, los pacientes con mayor BMI y varios diagnósticos tuvieron baja resonancia. Conclusión: la educación nutricional desarrollada es adecuada para el manejo del dolor crónico. Los mejores beneficios son un patrón mejorado de consumo de comida junto a un consumo reducido de alimentos con efecto proinflamatorio y antojos de alimentos. La complejidad del dolor crónico es visible en baja respuesta entre pacientes con mayor BMI y varios diagnósticos.

Influence of postoperative analgesia on systemic inflammatory response and postoperative cognitive dysfunction after femoral fractures surgery: a randomized controlled trial.

BACKGROUND AND OBJECTIVES: To investigate the possible effect of postoperatively applied analgesics-epidurally applied levobupivacaine or intravenously applied morphine-on systemic inflammatory response and plasma concentration of interleukin (IL)-6 and to determine whether the intensity of inflammatory response is related to postoperative cognitive dysfunction (POCD). METHODS: This is a randomized, prospective, controlled study in an academic hospital. Patients were 65 years and older scheduled for femoral fracture fixation from July 2016 to September 2017. Inflammatory response was assessed by leukocytes, neutrophils, C reactive protein (CRP) and fibrinogen levels in four blood samples (before anesthesia, 24 hours, 72 hours and 120 hours postoperatively) and IL-6 concentration from three blood samples (before anesthesia, 24 hours and 72 hours postoperatively). Cognitive function was assessed using the Mini-Mental State Examination preoperatively, from the first to the fifth postoperative day and on the day of discharge. RESULTS: The study population included 70 patients, 35 in each group. The incidence of POCD was significantly lower in the levobupivacaine group (9%) than in the morphine group (31%) (p=0.03). CRP was significantly lower in the levobupivacaine group 72 hours (p=0.03) and 120 hours (p=0.04) after surgery. IL-6 values were significantly lower in the levobupivacaine group 72 hours after surgery (p=0.02). The only predictor of POCD in all patients was the level of IL-6 72 hours after surgery (p=0.03). CONCLUSIONS: There is a statistically significant association between use of epidural levobupivacaine and a reduction in some inflammatory markers. Postoperative patient-controlled epidural analgesia reduces the incidence of POCD compared with intravenous morphine analgesia in the studied population. TRIAL REGISTRATION NUMBER: NCT02848599.

Radiopaque Gelified Ethanol Application in Lumbar Intervertebral Soft Disc Herniations: Croatian Multicentric Study.

Objective: Minimally invasive percutaneous spinal procedures are popular in trying to reduce spinal pain. The aim of this paper is to evaluate the safety of intervertebral disc chemonucleolysis and to report the effectiveness of a percutaneous, minimally invasive treatment for contained herniated intervertebral discs in the lumbar spine using the recently marketed radiopaque gelified ethanol. Methods: Pain relief before and after the procedure was self-evaluated by each patient using a verbal numeric scale (VNS) ranging from 0 to 10. Patients were also scored prior to procedure and after chemonucleolysis during several follow-up periods using the Roland-Morris low back pain and disability questionnaire (RMQ). Follow-up periods were defined as 0-6, 6-12, 12-18, 18-24, and 24-30 months. Clinically significant functional improvement (CSFI) was defined as a decrease of five or more points on the RMQ scale and a decrease of at least 50% of pain intensity using VNS. Results: Using the RMQ scale, CSFI was achieved in 20/29 patients in the first follow-up period, 20/27 patients in the second follow-up period, 9/12 patients in the third follow-up period, 8/9 patients in the fourth follow-up period, and 4/4 patients in the last follow-up period. Using the VNS rating, CSFI was accomplished in 19/29 patients in the first follow-up period, 19/27 patients in the second follow-up period, 9/12 patients in the third follow-up period, 8/9 patients in the fourth follow-up period, and 4/4 in the last follow-up period. Conclusions: Intradiscal application of gelified ethanol may be effective in pain reduction using the VNS and Roland-Morris low back pain and disability questionnaire. The treatment is safe and easy to handle.

Pain syndromes originating from cervical and thoracic spine remain to be a major public health problem. Medical expenses in general and surgical procedures associated with overall care for the neck and thoracic pain are high and growing. Furthermore, these two chronic pain conditions are also leading causes for missed workdays. Chronic pain syndromes originating from cervical spine are most commonly caused by degenerative changes of the facet joints. Cervi- cobrachial syndrome is most commonly caused by herniated discs. Diagnostic controlled blocks, performed in order to identify, the source of pain, often predetermine patient for further therapeutic minimally invasive interventions. If the chronic pain syndromes of the cervical and thoracic spine are caused by degenerative facet joints, patient can be offered neuroablative procedures using radiofrequency. In patients suffering from chronic cervical and thoracic pain caused by painful intervertebral disc minimally invasive intradiscal decompression procedures can be performed. In cases where the neck pain and radicular pain are caused by the central and foraminal spinal stenosis patients are advised epidural steroid injections. The purpose of above advised procedures, using steroids, local anesthetics and RF current, is to relieve patients' pain, allow optimal physical therapy, and improved functional capacity, consequently providing a better quality of life.

Low back and radicular pain recently became a major public health problem. Medical expenses in general, and surgical procedures associated with overall care for the lower back pain are high and growing. Furthermore, these two chronic pain conditions are also leading causes for missed workdays. Degenerative changes of the intervertebral disc, facet joints, sacroiliac joint or disc herniation as described during imaging diagnostics may or may not be the cause of patients' lower back pain. Diagnostic blocks often precede further interventions in order to confirm or dispute a source of the lower back pain. Chronic lower back pain caused by painful intervertebral disc should be treated using biacuplasty. If the pain of the lumbar spine is caused by facet joints or sacroiliac joint, patient can be offered neuroablative procedures using radiofrequency. In cases where the low back and radicular pain are caused by the central and foraminal spinal stenosis patients are advised epidural steroid injections, unless claudications are present. Patients suffering from the chronic radicular pain may be treated with various nucleoplasty procedures or they may be offered percutaneous radiofrequent neuromodulation. The purpose of above advised procedures is to relieve patients' pain, allow optimal physical therapy, and improved functional capacity, consequently providing better quality of life.

painDETECT questionnaire and lumbar epidural steroid injection for chronic radiculopathy.

BACKGROUND: The painDETECT questionnaire (PD-Q) is a fast and uncomplicated way to ascertain the percentage of neuropathic pain in 'total pain' and is designed to detect neuropathic pain components in back pain. The purpose of this randomized, prospective study is to compare, with the assessment of the PD-Q, the efficacy of interlaminar (IL) and transforaminal (TF) steroid injections in patients with unilateral chronic lumbar radicular pain. METHODS: Patients were treated fluoroscopically with epidural steroids, using the IL or TF method and with confirmation of the epidural space by contrast, using random computerized classification. The patients received a series of three IL or TF epidural steroid injections (ESI) at 2-week intervals. The patients were monitored for 6 months from the first steroid injection. RESULTS: By analyzing the average values of the total sum of points in the PD-Q a dropping trend is confirmed for both groups. The trend equation (y = -1.1393x + 25.269) for the TF ESI shows a faster recovery than the IL ESI (y = -0.8089x + 26.654). The statistically significant difference in the two groups is proved between the first and the sixth visit (IL ESI, p = 0.014; TF ESI, p = 0.001). There is no statistically significant difference in the efficiency of the two dosages and the volumes of steroids between the IL and TF distribution of steroids. CONCLUSIONS: Steroids are efficient; besides alleviating the overall pain, they also reduce the neuropathic component in chronic lumbar radicular pain, whether it is distributed epidurally by the IL or TF approach.

Efficacy of interlaminar vs transforaminal epidural steroid injection for the treatment of chronic unilateral radicular pain: prospective, randomized study.

UNLABELLED: OBJECTIVE, DESIGN AND SETTINGS: The purpose of this randomized, prospective study is to compare the efficacy of two different routes in administering epidural steroid injections interlaminar (IL) vs transforaminal (TF) in patients with unilateral radicular pain. PATIENTS: We randomly enrolled and followed 64 patients with chronic radiculopathy. RESULTS: Significant improvements were maintained throughout 6 months (24 weeks) of follow-up (P<0.001, respectively). The average visual analog scale (VAS) pain scores at 24 weeks improved to 4.0 ± 2.2 cm in the IL group and 3.8 ± 2.1 cm in the TF group (P=0.717). Baseline functional capacity was comparable for the IL and the TF group (52% vs 53%) when assessed using Oswestry (P=0.647). At 6 months, both groups improved, 39% for the IL group and 38% for the TF group, suggesting change from severe to moderate disability scoring range. There were 24 out of the 32 (75%) patients in the IL group at 24 weeks who improved more than 2 cm on the VAS scale and 17 patients (53%) had >50% of the pain relief. In the TF group, there were 27 out of the 32 (84%) patients with >2 cm improvement on VAS pain scale, and 20 of 32 (63%) with >50% improvement at 24 weeks. Functional capacity changes were similar, 16 out of the 32 patients (50%) improved 10 points or more on the Oswestry scale in the IL group and 21 out of the 32 in the TF group (66%). CONCLUSIONS: Using either route of epidural injections to deliver steroids for unilateral chronic radiculopathy secondary to herniated intervertebral disc provided significant improvements in patients function and pain relief. However, we could not find a statistically significant difference between two indicated groups either in functional improvement or in reduction in pain, although half-dose of steroids delivered via TF route provided somewhat better long-term pain relief and functional capacity improvements.
