Spinal Cord Stimulation vs Medical Management for Chronic Back and Leg Pain: A Systematic Review and Network Meta-Analysis.

Chronic back and lower extremity pain is one of the leading causes of disability worldwide. Spinal cord stimulation (SCS) aims to improve symptoms and quality of life. To evaluate the efficacy of SCS therapies compared with conventional medical management (CMM). MEDLINE, Embase, and Cochrane Library were systematically searched from inception to September 2, 2022. Selected studies were randomized clinical trials comparing SCS therapies with sham (placebo) and/or CMM or standard treatments for adults with chronic back or leg pain who had not previously used SCS. Evidence synthesis estimated odds ratios (ORs) and mean differences (MDs) and their associated credible intervals (CrI) through bayesian network meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for network meta-analyses was followed. The primary outcomes were pain-related end points, including pain intensity (measured by visual analog scale) and proportion of patients achieving at least 50% pain relief (responder rate) in the back or leg. Quality of life (measured by EQ-5D index score) and functional disability (measured by the Oswestry Disability Index score) were also considered. A total of 13 studies of 1561 patients were included in the network meta-analysis comparing conventional and novel SCS therapies with CMM across the 6 outcomes of interest at the 6-month follow-up. Both conventional and novel SCS therapies were associated with superior efficacy compared with CMM in responder rates in back (conventional SCS: OR, 3.00; 95% CrI, 1.49 to 6.72; novel SCS: OR, 8.76; 95% CrI, 3.84 to 22.31), pain intensity in back (conventional SCS: MD, -1.17; 95% CrI, -1.64 to -0.70; novel SCS: MD, -2.34; 95% CrI, -2.96 to -1.73), pain intensity in leg (conventional SCS: MD, -2.89; 95% CrI, -4.03 to -1.81; novel SCS: MD, -4.01; 95% CrI, -5.31 to -2.75), and EQ-5D index score (conventional SCS: MD, 0.15; 95% CrI, 0.09 to 0.21; novel SCS: MD, 0.17; 95% CrI, 0.13 to 0.21). For functional disability, conventional SCS was superior to CMM (MD, -7.10; 95% CrI, -10.91 to -3.36). No statistically significant differences were observed for other comparisons. This systematic review and network meta-analysis found that SCS therapies for treatment of chronic pain in back and/or lower extremities were associated with greater improvements in pain compared with CMM. These findings highlight the potential of SCS therapies as an effective and valuable option in chronic pain management.

Ballooning and Bursting of Barrels and Pipes: A Rare Case of Suspected Vascular Ehlers–Danlos Disease

Vascular Ehler–Danlos disease (vEDS), a rare subtype of a rare disease, is a life-threatening disease, with an increased risk for spontaneous vascular or visceral rupture. These patients have fatal complications ranging from vascular aneurysms, dissection, and rupture of systemic vessels to frequent thromboembolic events, the common causes of death in these individuals with a shortened life span. In the present case, a 28-year-old male with history of shoulder dislocations and spontaneous colon perforation presented to the primary care clinic with right lower extremity swelling and pain. His history includes presentation to the emergency department with left lower leg swelling with compartment syndrome one year prior. A CT angiogram of lower extremities and abdomen revealed acute arterial extravasation of the left posterior tibial artery, indicating a ruptured aneurysm along with aneurysms of the splenic artery and left common iliac artery. He was treated with a saphenous vein graft, but was associated with post-operative complications that necessitated below-knee amputation. CT angiogram of his right leg revealed occlusion of the anterior tibial and peroneal arteries with aneurysms, and, ultimately, he was referred to a tertiary care center for aneurysm embolization. This case report emphasizes the frequent vascular complications encountered in vascular EDS patients, and thus advocates for close and regular monitoring for early referral and surgical management of their vascular anomalies. Finally, genetic counseling and screening of asymptomatic family members should be routinely implemented in these patients.

The occurrence of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) after arthroplasty mimicking a periprosthetic joint infection: A case report and literature review.

As the elderly population grows, the number of joint arthroplasty surgeries is also increasing. Periprosthetic joint infection (PJI) is a postoperative complication that occurs in 1%-2% of the arthroplasties. Once it occurs, PJI is refractory to treatment. Similar symptoms of PJI, including joint synovitis and elevated body temperature, sometimes arise because of crystal arthritis, rheumatoid arthritis, or other inflammatory diseases. Precise diagnosis is essential for determining the optimal treatment strategy. An 81-year-old female patient with a history of bilateral knee arthroplasty presented with a high fever of 38 °C and was unable to walk due to swelling and pain in the bilateral lower extremities. Infectious conditions, such as cellulitis or PJI, were suspected. Imaging findings revealed bilateral knee joint synovitis with pitting edema around the lower extremities, and cultures of bilateral joint fluids were negative. No crystals were observed in the joint fluid. Laboratory data revealed highly elevated levels of inflammatory marker; however, antinuclear antibodies, including rheumatoid factor and cyclic citrullinated peptide, were not detected. Based on bilateral synovitis with pitting edema in the lower extremities, in addition to negative culture findings and normal antinuclear antibodies, the diagnosis of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) was made. Steroid therapy was performed. The dose was gradually reduced, with the improvement of the symptoms. The inflammatory reaction promptly decreased and then normalized. With improved inflammation, the symptoms of pitting edema, pain in the bilateral lower extremities, and fluid effusion of the knee joints were reduced. She was able to walk without a cane, and her activities of daily living fully recovered. High fever and synovitis after joint arthroplasty do not necessarily indicate an infectious condition. Clinicians should be familiar with the occurrence of RS3PE, regardless of whether arthroplasty is performed.

Lower urinary tract symptoms (LUTS) as a clinical feature of lumbar spinal stenosis (LSS): a prospective study with lumbar spine morphometry analysis

<p><strong>Aim</strong> To investigate clinical and morphometric characteristics of patients with lower urinary tract symptoms (LUTS) due to lumbar spinal stenosis (LSS).<br /><strong>Methods</strong> This study evaluated LSS patients using clinical assessments of motor, sensory, bladder, and bowel functions, and functional disability scores from the Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSSQ). Morphometric analysis included MRI measurements of the anteroposterior diameter of the intervertebral disc and dural sac, and the modified Torg-Pavlov ratio (mTPR), with follow-up re-evaluations at 6 months.<br /><strong>Results</strong> Of 159 patients, 49 (30.8%) had LUTS and 110 (69.2%) were in the control group. LUTS patients had a significantly higher prevalence of neurogenic claudication (100% vs. 47.3%; p<0.001), lower back pain (93.9% vs. 77.3%; p=0.011), and lower extremity pain (57.1% vs. 34.5%; p=0.008). The LUTS group also had higher ODI (54.0 vs. 50.0; p=0.019) and SSSQ score (44.0 vs. 34.0; p<0.001). Morphometric analysis showed significantly lower mTPR in LUTS patients (median 0.31 vs. 0.45; p<0.001), with an AUC of 0.704 (95%CI 0.627-0.774). mTPR≤0.31 predicted surgical revision within 6 months (OR:3.4, CI: 1.2-9.8), motor deficiency (OR:2.1, 95%CI: 1.4-5.2), and persistent LUTS post-surgery (OR:4.5, 95%CI: 1.1-18.9). mTPR≤0.34 was associated with worse follow-up outcome, including increased ODI (β:3.2; 95%CI: 1.1-5.3; p=0.004) and SSSQ score (β:4.8; 95%CI:2.1-7.5).<br /><strong>Conclusion</strong> LUTS patients with LSS exhibit more severe symptoms and poorer outcome, with mTPR≤0.34 being a predictor of adverse clinical outcome and the need for surgical revision within 6 months.</p>

Surgical Management of Thoracic Dorsal Arachnoid Webs: A 10-Year Single-Institution Experience

ObjectiveThoracic dorsal arachnoid webs are intradural membranes that may cause obstruction of CSF flow and spinal cord compression. While well-recognized, they are rare and there is a paucity of long-term data on their natural history and prognosis. We reviewed radiographic features, surgical indications, and pathologic specimens of patients diagnosed with focal thoracic dorsal arachnoid webs. MethodsA radiology database and surgical case logs were queried for thoracic arachnoid webs at a single hospital system for a ten-year period. A retrospective chart review was performed on identified cases. ResultsWe identified 127 patients with dorsal thoracic arachnoid webs. Arachnoid webs were radiographically classified into three morphologic types: Type 1 (54%) causing spinal cord deformity only, Type 2 (32%) producing cord deformity with myelomalacia, and Type 3 (14%) with cord deformity, myelomalacia, and syringomyelia. These arachnoid webs were commonly centered at the upper thoracic T4 segmental level. Forty-one cases (32%) required surgery, generally for thoracic myelopathy with gait instability (46%) and lower extremity numbness and pain (39%). In patients who underwent surgery, 79% experienced symptomatic improvement and 21% remained stable, after an average of 21 months follow-up evaluation. Surgical pathology revealed fibrous connective tissue (100%) with calcifications (26%) or inflammation (7%). ConclusionsThe majority in a large series of patients with dorsal arachnoid webs did not undergo surgical intervention, but those with myelomalacia and syrinx experienced radiographic and clinical deterioration without surgery. Surgery to treat symptomatic arachnoid webs results in significant clinical improvement with low surgical morbidity.

Unilateral Biportal Endoscopic Decompression for Thoracic Spinal Stenosis Secondary to Ossification of the Ligamentum Flavum

Ossification of the ligamentum flavum (OLF) in the thoracic spine is a cause of thoracic myelopathy that is more commonly found in East Asian populations (Koreans, Japanese, Chinese) than in others. Early diagnosis and sufficient surgical decompression can improve the functional prognosis for thoracic OLF. Surgical decompression is necessary and should be done as soon as the symptoms develop. There is a wide range of possible treatments, from standard open laminectomy to endoscopic decompression surgery. This video demonstrates the least invasive technique of decompressive laminectomy with bilateral decompression and removal of thoracic OLF through unilateral biportal endoscopic spinal surgery. The authors present the case of an 81-year-old male patient who presented with bilateral lower extremity weakness, numbness, pain, and ataxia. Magnetic resonance imaging and computed tomography scans of the whole spine showed the presence of OLF with severe spinal canal stenosis and a cord signal change at the T9–10 level. He underwent biportal endoscopic decompression and removal of thoracic OLF at T9–10. On the discharge day (postoperative day 7), motor power and pain had significantly improved. He could stand and independently ambulate with a walker.

A study to explore the role of a low threshold, fitness focussed physical rehabilitation intervention with protein supplementation to target physical function and frailty in people with problematic substance use and homelessness: protocol for a single-arm pre-post intervention study.

Background People who are homeless are more likely to experience poor mental health and addiction as well as suffering from non-communicable diseases. There is evidence of frailty and accelerated physical ageing among people experiencing homelessness. Appropriate physical rehabilitation and nutritional supplementation strategies can stabilise or reverse frailty and general physical decline, but it is not known how this type of intervention would work in practice in this population. Aim To evaluate the feasibility and pre-post intervention impact of a low threshold physical rehabilitation intervention with protein supplementation to target physical functioning and frailty in people with problematic substance use who are experiencing homelessness. Methods The intervention will consist of a 12-week low threshold rehabilitation programme with protein supplementation. Participants will be service users of the Ballyfermot Advance Project, a day services centre for people with addiction issues and experiencing homelessness. Primary outcomes will be feasibility including numbers recruited, retention of participants and adherence to the exercise intervention and protein supplement. Any adverse events will be recorded. Secondary outcomes will be strength and muscular mass, physical performance and lower extremity physical function, pain, frailty and nutritional status. Discussion An immediate impact may be simply a distraction from difficult circumstances and potentially an improvement of physical health of participants, which can be a conduit for the emergence of other positive behaviours and recovery. Longer term, this study will generate preliminary data on which to inform the design of a definitive randomised controlled trial of physical rehabilitation and protein supplementation, if indicated. Ethics and dissemination Ethical approval was granted by the Faculty of Health Sciences Research Ethics Committee in TCD. Study findings will be disseminated through publication into an international peer-reviewed journal and presented at national and international conferences.

Endoscopic and microsurgical decompression for central lumbar spinal stenosis

Objective. To perform comparative analysis of the results of endoscopic and microsurgical decompression for lumbar spinal stenosis.Material and Methods. Design: Retrospective monocentric intra-cohort comparison of two groups of patients. The study included 99 patients aged 51–88 years with clinically significant lumbar spinal stenosis manifested by neurogenic intermittent claudication syndrome. Endoscopic decompression was performed in 51 patients, and microsurgical decompression – in 48 patients. To objectify and standardize clinical symptoms, walking distance in meters, pain syndrome and quality of life were assessed before and after surgery using standard scales and questionnaires (VAS, ODI). On the first day after surgery, back and lower limb pain were assessed, and during the observation period back and lower limb pain, quality of life and walking distance were assessed. Functional lumbar radiography was performed to exclude instability of the spinal motion segment. Using MRI, the cross-sectional area of the dural sac at the level of stenosis was measured before and after surgery. Clinical efficacy was assessed using the MCID (Minimal Clinical Important Difference) criterion. The results of the operation were followed-up for 12 months after the operation.Results. Blood loss in the endoscopic intervention group was less than in the microsurgical group. Pain in the lumbar spine and in the lower extremities decreased, and the cross-sectional area of the dural sac increased. In the first days after surgery, patients after endoscopic decompression had less severe back and lower extremity pain than patients after microsurgical decompression due to less soft tissue trauma. Pain syndrome in back 10–12 months after surgery was without statistically significant difference between the groups. Patients after endoscopic decompression had statistically significantly better quality of life according to ODI, lesser pain in the lower extremities according to VAS and longer walking distance than those in the microsurgical decompression group. Surgical treatment in both groups turned out to be effective, which is confirmed by MCID. The time of endoscopic intervention is significantly longer than that of microsurgical intervention. The length of the incision during endoscopic decompression is shorter than that of microsurgical decompression.Conclusion. A comparative analysis of the results of endoscopic and microsurgical decompression for degenerative central lumbar stenosis showed comparable effectiveness of both methods, including an increase in the spinal canal dimension and ensuring regression of clinical symptoms. The results of the comparison do not allow making a sufficiently substantiated judgment on the advantages of one of the methods, which dictates the need for further research.

7073 Treasure or Terror: Dilemmas in the Management of a Giant Parathyroid Adenoma

Abstract Disclosure: A.D. Galia: None. R. De Guzman: None. S. Suib - Salvilla: None. Background: Primary hyperparathyroidism is a common endocrine disorder with an incidence of 25 per 100,000 people in the general population. More commonly caused by parathyroid adenomas in 80-85%, giant parathyroid adenomas weighing more than 3.5 g or measuring more than 2 cm may rarely occur. There have been no reported prevalence data of parathyroid adenoma among ASEAN countries, especially in the Philippines. Clinical Case: A 43-year-old, female, Filipino, initially asymptomatic with anterior neck mass for 8 years then presented with generalized body malaise, easy fatigability, lower extremities pain and numbness. Six years ago, neck ultrasound showed left thyroid nodule; abdominal sonogram showed bilateral medullary nephrocalcinosis, with hypercalcemia, elevated intact PTH, and elevated creatinine. She was unable to undergo further workup and management until she presented a few months ago because of generalized body malaise, abdominal pain, nausea, and vomiting because of hypercalcemia and non-oliguric renal failure. Serum ionized calcium was 1.90 mmol/L (NV 1.15 - 1.30), intact PTH 2000 pg/mL, and serum creatinine 6.08 mg/dL. With unavailability of calcitonin and pamidronate, medical management of hypercalcemia included cautious hydration followed by diuresis, zoledronic acid, and cinacalcet. Sestamibi scan showed a large parathyroid adenoma. Bone densitometry showed osteoporosis (T score = below -2.5). After medical evaluation, she underwent parathyroidectomy under general anesthesia. Intact PTH level perioperatively were as follows: pre-op = 2,078.2 pg/mL; 30 mins = 477.1 pg/mL; 1 hour = 335.7 pg/mL, 1 day = 67.2 pg/mL. The resected mass was 4.2 x 2.4 x 1.6 cm and weighed 4 g; histopathology report was consistent with Parathyroid Adenoma. Post-operatively, patient did not develop hungry bone syndrome. Conclusion: Giant parathyroid adenoma is a rare condition that is usually asymptomatic but can lead to serious complications. In the Philippines, limited availability of laboratory techniques (PTH and sestamibi scan) and availability of medications for hypercalcemia may contribute to underdiagnosis and management. Early detection and treatment can help prevent further complications and improve the overall quality of life. Presentation: 6/3/2024

Efficacy and Safety of Biportal Endoscopic Decompressive Laminectomy in Octogenarians With Severe Lumbar Spinal Stenosis.

Lumbar spinal stenosis (LSS) is prevalent among octogenarians, causing significant pain and disability. Surgical intervention is often required because of the ineffectiveness of conservative treatments. This study investigates the efficacy and safety of biportal endoscopic decompressive laminectomy (BED) in octogenarians with severe LSS, evaluating its potential as a minimally invasive surgical option. This retrospective study included 107 patients aged 80 years or older who underwent BED for LSS between March 2017 and December 2022. Data were collected from electronic medical records, including demographic information, clinical outcomes, and surgical details. Patients with fractures, infectious spondylitis, herniated discs, and follow-up less than 12 months were excluded. Clinical outcomes were assessed using the visual analog scale, Oswestry Disability Index, European Quality of Life-5 Dimensions, and painDETECT at baseline and at 3, 6, and 12 months after surgery. The mean age of the 107 patients was 84.1 years, with 59% being women. Significant improvements were observed in visual analog scale scores for lower back and lower extremities pain, Oswestry Disability Index, European Quality of Life-5 Dimensions, and painDETECT scores, indicating reduced pain, decreased disability, and enhanced quality of life. There were no significant differences in outcomes between patients aged 80 to 84 and those 85 or older. Surgery-related outcomes such as operation time, blood loss, and complications were similar in both age groups. BED is a safe and effective treatment for LSS in octogenarians, providing significant pain relief and functional improvement. This minimally invasive technique is also viable for patients older than 85 years, without increased risk of complications, supporting its broader indications in managing LSS in the elderly. This study highlights the efficacy and safety of BED for LSS in octogenarians, demonstrating its potential to improve quality of life and function with low risks, making it a feasible option for elderly patients.

A Comparative Analysis of Patient-Reported Outcomes Following Free Tissue Transfer, Partial Foot Amputation, and Below-Knee Amputation in High-Risk Limb Salvage Patients.

The surgical decision for limb-salvage with free tissue transfer (FTT), partial foot amputation (PFA), or below-knee amputation (BKA) for complex lower extremity (LE) wounds hinges on several factors, including patient choice and baseline function. However, patient-reported outcome measures (PROMs) on LE function, pain, and QoL for chronic LE wound interventions are limited. Thus, the study aim was to compare PROMs in patients who underwent FTT, PFA, or BKA for chronic LE wounds. PROMs were collected via QR code for all adult chronic LE wound patients who presented to a tertiary wound center between June 2022 and June 2023. A cross-sectional analysis of patients who underwent FTT, PFA, or BKA was conducted. The 12-Item Short Survey (SF-12), PROM Information System Pain Intensity (PROMIS-3a), and Lower Extremity Functional Scale (LEFS) were completed at 1, 3, and 6 months and 1, 3, and 5 years postoperatively. Patient demographics, comorbidities, preoperative characteristics, and amputation details were collected. Of 200 survey sets, 71 (35.5%) underwent FTT, 51 (25.5%) underwent PFA, and 78 (39.0%) underwent BKA. Median postoperative time points of survey completion between FTT (6.2 months, IQR: 23.1), PFA (6.8 months, IQR: 15.5), and BKA (11.1 months, IQR: 21.3) patients were comparable (P = 0.8672). Most patients were male (n = 92, 76.0%) with an average age and body mass index (BMI) of 61.8 ± 12.6 years and 30.3 ± 7.0 kg/m2, respectively. Comorbidities for FTT, PFA, and BKA patients included diabetes mellitus (DM; 60.6% vs 84.2% vs 69.2%; P = 0.165), peripheral vascular disease (PVD; 48.5% vs 47.4% vs 42.3%; P = 0.790), and chronic kidney disease (CKD; 12.1% vs 42.1% vs 30.8%; P = 0.084). No significant differences were observed between FTT, PFA, and BKA patients in mean overall PROMIS-3a T-scores (49.6 ± 14.8 vs 54.2 ± 11.8 vs 49.6 ± 13.7; P = 0.098), LEFS scores (37.5 ± 18.0 vs 34.6 ± 18.3 vs 38.5 ± 19.4; P = 0.457), or SF-12 scores (29.6 ± 4.1 vs 29.5 ± 2.9 vs 29.0 ± 4.0; P = 0.298). Patients receiving FTT, PFA, or BKA for chronic LE wounds achieve comparable levels of LE function, pain, and QoL postoperatively. Patient-centered functionally based surgical management for chronic LE wounds using interdisciplinary care, preoperative medical optimization, and proper patient selection optimizes postoperative PROMs.

Among people with a non-traumatic lower extremity condition, is pain in the contralateral lower extremity associated with unhelpful thoughts and distress regarding symptoms?

ObjectiveWhen patients with non-traumatic lower extremity conditions express concerns regarding symptoms of the contralateral lower extremity they may be communicating fear of painful movement. Among people seeking specialty care for unilateral non-traumatic lower extremity conditions, we studied the relationship between magnitude of incapability and pain intensity in the contralateral and ipsilateral limbs and thoughts and feelings about sensations. MethodsPatients seeing a musculoskeletal specialist for any unilateral non-traumatic lower extremity condition were enrolled. We used multivariable analysis to identify aspects of unhelpful thinking and feelings of distress associated with contralateral and ipsilateral pain intensity and magnitude of capability accounting for demographic factors. ResultsGreater pain intensity in the contralateral limb, greater pain intensity in the ipsilateral limb, and higher magnitude of incapability were all associated with greater distress regarding symptoms. ConclusionsWhen patients voice concerns about pain in the contralateral limb, they may be signaling feelings of worry or despair regarding symptoms. Practice implicationsConcerns about pain in the contralateral limb can prompt clinicians to explore feelings of worry or despair regarding symptoms, an important and modifiable aspect of musculoskeletal illness.

Percutaneous endoscopic transforaminal decompression surgery for symptomatic double-level lumbar spinal stenosis with ossification.

This study aimed to explore the short-term effects of percutaneous endoscopic transforaminal decompression (PETD) for the treatment of symptomatic double-level lumbar spinal stenosis (LSS) with ossification. Twenty-eight patients diagnosed with double-level lumbar spinal stenosis who underwent double-level PETD surgery between January 2021 and January 2023 at our institution. General information, such as age, sex, disease duration, hospitalization time, and operation time, was recorded. Magnetic resonance imaging (MRI) dural sac cross-sectional area (DSCA) was recorded to assess the degree of spinal canal decompression. The White-Panjabi scoring system (WP) was used to assess preoperative and postoperative lumbar spine stability. Pre- and postoperative visual analog scale (VAS) and Oswestry Disability Index (ODI) scores were recorded to assess symptom improvement, and surgical efficacy was evaluated using the modified Macnab evaluation criteria at the 1-year postoperative follow-up. The types and risks of complications were also recorded. The patient's 1-year postoperative follow-up MRI showed that both L3/4 and L4/5 DSCA were significantly enlarged compared with preoperative values (P < .001). There was no significant difference in the WP scores at 3 months postoperatively compared with those preoperatively (P > .05). The VAS scores for hip and lower extremity pain at 3 days, 3 months, and 1 year postoperatively were significantly lower than those preoperatively (P < .001), and the ODI scores at 3 months and 1 year postoperatively were significantly lower than those preoperatively (P < .001). There were no significant differences in hip pain, lower extremity pain VAS scores, or ODI scores between the postoperative follow-up time points (P > .05). There was 1 case of lower limb numbness and 1 case of neuroedematous pain in the postoperative period, and all patients had no complications, such as dural sac tear, infection, or recurrence. The 1-year postoperative follow-up was assessed as excellent in 17 cases, good in 9 cases, and possible in 2 cases using the modified Macnab criteria, with an excellent rate of 92.9%. The efficacy of double-level PETD for symptomatic double-level LSS is clear, the local stability of the lumbar spine is less affected, and the risk is low, which can reduce the chances of reoperation in patients. Thus, it is a recommended surgical procedure.

Smart working during the COVID-19 pandemic: the prevalence of musculoskeletal and visual disorders in administrative staff of a large international company.

During the COVID-19 Pandemic, the use of digital devices during work activities has increased with important re-percussions on the psychological and physical well-being of the employees. The aim of this study was to investigate the prevalence of musculoskeletal and visual disorders related to the use of computers and home workstation. The study is a cross-sectional study. A checklist, from the National Institute of Health, was administered to white collar workers of a large international pharmaceutical company based in Italy. Our study showed that postural breaks have a protective effect on neck/shoulder pain (OR 0.32, CI 0.16-0.62), back and lower extremity pain (OR 0.35, CI 0.18-0.69), and eye burning (OR 0.50, CI 0.27-0.94) of study participants. The research recommends that remote employees who often change their workstations should establish a suitable work environment and obtaining enough risk training from an occupational physician. This is essential for maintaining their mental and physical well-being.

Dynamic Functional Ability in Lacrosse Players in Relation to Development of Sport-Related Onset of Musculoskeletal Pain.

Unlike other sports, the relationship between performance deficits and pain/injury in lacrosse players has not been well-investigated. The purposes of this study were to: 1) determine whether age and sex differences exist in dynamic physical function tests and drop jump performance among lacrosse players, and 2) determine whether pre-seasonal physical function scores predict onset of either lower extremity or low back pain over time. Prospective observational study. Lacrosse players (N=128) were stratified into three groups: 12-14.9 yrs, 15-18 yrs and >18 yrs. Thomas test (hip flexibility), Ober's test (iliotibial band tightness), and Ely's test (rectus femoris tightness) were performed. Landing Error Scoring System (LESS) scores were collected while players performed drop jumps. Sagittal and frontal plane movement from 2D video during single and double legged squats was assessed. Musculoskeletal pain symptoms or injury were tracked for six months. Age bracket, sex and physical function scores were entered into logistic regression models to determine risk factors that predicted onset of lower extremity pain and low back pain onset. LESS scores and single-leg squat movement quality test scores were lowest in the 12-14.9 yr groups and highest in the >18 yr group (all p<0.05). Single leg squat performance score increased the odds risk (OR) for lower extremity pain (OR=2.62 [95% CI 1.06-6.48], p=.038) and LESS scores elevated risk for low back pain onset over six months (OR = 2.09 [95% CI 1.07- 4.06], p= .031). LESS scores and single legged squat performance may help identify lacrosse players at risk for musculoskeletal pain or injury onset. Detecting these pertinent biomechanical errors and subsequently developing proper training programs could help prevent lower extremity and low back pain onset. III.

Lower extremity pain and/or numbness after laparoscopic surgery and robot-assisted surgery in the lithotomy position combined with the Trendelenburg position.

The purpose of this study was to investigate the incidence and risk factors of lower extremity pain and/or numbness after laparoscopic colorectal surgery and robot-assisted laparoscopic radical prostatectomy in the lithotomy position combined with the Trendelenburg position. The relationship between creatine kinase (CK) levels and lower extremity pain and/or numbness was also investigated. We retrospectively reviewed adult patients who underwent laparoscopic colorectal surgery and robot-assisted laparoscopic radical prostatectomy in the lithotomy position combined with the Trendelenburg position between May 2015 and April 2020. Logistic regression analysis was used to identify risk factors of lower extremity pain and/or numbness. Preoperative and postoperative CK levels were compared in patients with and those without lower extremity pain and/or numbness. Among 940 patients, 1.9% experienced lower extremity pain and/or numbness postoperatively. The incidences of lower extremity pain and/or numbness after laparoscopic colorectal surgery and after robot-assisted laparoscopic radical prostatectomy were 1.7% and 2.1%, respectively. Multivariate logistic regression analysis revealed that only duration of surgery > 4h (odds ratio = 3.144, 95% CI: 1.102-8.969, p = 0.032) was a significant predictor of lower extremity pain and/or numbness. Postoperative median CK level in patients with lower extremity pain and/or numbness was significantly higher than that in patients without lower extremity pain and/or numbness. The incidence of lower extremity pain and/or numbness after laparoscopic colorectal surgery was comparable to that after robot-assisted laparoscopic radical prostatectomy. Prolonged duration of surgery contributed to lower extremity pain and/or numbness. Significantly elevated CK levels in patients with lower extremity pain and/or numbness suggest the involvement of muscle injury in these symptoms.

Comparison of Full Endoscopic Lumbar Diskectomy Using the Transforaminal Approach versus Interlaminar Approach for L5-S1 Lumbar Disk Herniation Treatment: A Meta-Analysis.

Numerous studies have examined the clinical effectiveness of transforaminal full endoscopic lumbar diskectomy (T-FELD) and interlaminar full endoscopic lumbar diskectomy (I-FELD) for L5-S1 lumbar disk herniation (LDH), with mixed findings. The goal of this systematic review and meta-analysis was to evaluate the perioperative outcomes, clinical results, and complications of T-FELD and I-FELD to determine their efficacy and safety for treating L5-S1 LDH and to examine the features of complications in depth. Several databases were searched for articles that matched all of the inclusion criteria. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were used to assess the clinical results. Information on perioperative outcomes and complications was gathered and analyzed. Eight studies with 756 participants were included. There were no significant differences in postoperative bed time (p = 0.44) and hospitalization time (p = 0.49) between T-FELD and I-FELD. When compared with I-FELD, T-FELD was associated with substantially longer fluoroscopy time (p < 0.0001) and operating time (p < 0.0001). There were no significant differences in the preoperative and postoperative VAS and ODI scores between T-FELD and I-FELD. The rates for overall complications, postoperative dysesthesia, postoperative lower extremity pain, incomplete decompression, recurrence, and conversion to open surgery were comparable for T-FLED and I-FELD. T-FELD and I-FELD had equal clinical results and safety for treatment of L5-S1 LDH. Fluoroscopy and operative times were shorter for I-FELD than for T-FELD.

Health behaviours and work-related musculoskeletal pain among polish physiotherapists and nurses.

Physiotherapists and nurses play crucial roles in healthcare, often requiring them to adopt physically demanding positions. However, these positions can lead to joint stress and an increased risk of injury, as well as work-related musculoskeletal disorders (WRMSDs). These disorders can significantly impact the performance of their duties, which can negatively affect patient recovery. This study assessed and compared health behaviour and work-related musculoskeletal pain among Polish physiotherapists and nurses. The study encompassed a group of 304 participants. The methodology consisted of a survey addressing pain-related questions and the Health Behaviour Inventory (HBI). The HBI evaluates health behaviour in four categories. The average HBI score was 5.05 (±1.96) points for physiotherapists and 4.50 (±1.86) points for nurses (P = .01). When analysing the HBI components, a statistically significant difference was observed in positive mental attitude and health practices (P < .05). Regarding work-related musculoskeletal pain, 92% of nurses and 79% of physiotherapists reported experiencing pain while working (P < .01). Pain intensity, measured with the VAS, was 3.77 (±2.37) for physiotherapists and 4.73 (SD 2.04) for nurses (P < .01). Physiotherapists more often suffered from upper limb pain (57% vs 49%), while nurses experienced middle/lower back pain (82% vs 63%) and lower extremity pain (38% vs 23%) more frequently. Both professional groups experience WRMSDs, with nurses suffering more regularly and severely. In contrast, physiotherapists exhibit superior health behaviour practices, potentially mitigating musculoskeletal pain. Nonetheless, the prevalence of pain related to WRMSDs remains alarmingly high in both professions.

Self-reported prolonged standing work is not associated with lower back and lower extremity pain in viticulture workers

This cross-sectional study investigated the association between prolonged standing at work and pain in the lower back and lower limbs in viticulture workers. Prolonged standing was self-reported. Lower back and lower extremity pain were obtained using a 0-10 scale and categorized as “present” and “absent.” The association between standing work and the presence of pain was tested using binary logistic regression. 320 viticulture workers were evaluated. Participants were mainly female (78.4%), with a mean age of 36.2 (±9.1) years, 83.1% worked in the field, and 16.9% in packaging. The prevalence of pain was 50.3% for the lower back, 18.1% for the hip, 20.9% for the knee, and 24.4% for the ankle/foot. Logistic regression showed a negative association between dynamic standing at work and high-intensity pain in the lower back.

Polyarteritis nodosa complicated by renal aneurysm and intestinal perforation: A case report.

Polyarteritis nodosa (PAN) is a necrotizing vasculitis that affects small- and medium-sized arteries, presenting with diverse clinical manifestations. It can impact tissues and organs throughout the body and may be life-threatening in severe cases. Common causes of death include cardiac, renal, and gastrointestinal complications or aneurysm rupture. While separate reports of renal aneurysm and intestinal perforation exist, the coexistence of these conditions is rarely documented. This study reports a severe case of PAN complicated by both renal aneurysm and intestinal perforation, aiming to deepen the understanding of this disease, aid in clinical diagnosis and treatment, and improve patient prognosis. The patient presented to the hospital with dorsal foot pain and abdominal pain persisting for more than 4 months, along with pain and discomfort in both lower extremities for over 1 month. The patient was diagnosed with PAN, renal aneurysm, intestinal perforation, and grade 3 hypertension (high risk). After treatment, the patient showed normal temperature and blood pressure, relief from abdominal pain, and disappearance of myalgia and numbness in the lower limbs. Additionally, the renal aneurysm shrank significantly, the intestinal perforation healed, the ileostomy was reduced, and the patient's condition stabilized. The clinical symptoms of PAN mostly lack specificity, and should be distinguished from microscopic polyangiitis and simulated vasculitis. For patients with intestinal perforation similar to this case, tocilizumab treatment may be effective, but further research is needed to confirm it.
