Combined Ultrasound and Fluoroscopy versus Ultrasound versus Fluoroscopy-Guided Caudal Epidural Steroid Injection for the Treatment of Unilateral Lower Lumbar Radicular Pain: A Retrospective Comparative Study.

Background and Objectives: This study aimed to evaluate the mid-term effectiveness and safety of a combined ultrasound (US) and fluoroscopy (FL)-guided approach in comparison to US-guided and FL-guided caudal epidural steroid injections (CESI) for treating unilateral lower lumbar radicular pain. Materials and Methods: A total of 154 patients who underwent CESI between 2018 and 2022 were included. Patients were categorized into three groups based on the guidance method: combined US and FL (n = 51), US-guided (n = 51), and FL-guided (n = 52). The study design was retrospective case-controlled, utilizing patient charts and standardized forms to assess clinical outcomes, adverse events, complications during the procedures. Results: In all groups, Oswestry Disability Index and Verbal Numeric Scale scores improved at 1, 3, and 6 months after the last injection, with no significant differences between groups (p < 0.05). The treatment success rate at all time points was also similar among the groups. Logistic regression analysis showed that injection method, cause, sex, age, number of injections, and pain duration did not independently predict treatment success. Blood was aspirated before injection in 2% (n = 1), 13.5% (n = 7), and 4% (n = 2) of patients in the combined US and FL groups, FL-guided groups, and US-guided groups, respectively. Intravascular contrast spread was detected in one patient in the combined method groups and seven in the FL-guided groups. Conclusions: When comparing pain reduction and functional improvement, there was no significant difference between the three methods. The combined method took less time compared to using FL alone. The combined approach also showed a lower occurrence of intravascular injection compared to using FL alone. Moreover, blood vessels at the injection site can be identified with an ultrasound using the combined method. Given these advantages, it might be advisable to prioritize the combined US- and FL-guided therapy when administering CESI for patients with unilateral lumbar radicular pain.

Case Report: Upper limb superficial venous thrombosis associated with oral contraceptives mimicking soft tissue mass.

Background: Venous thrombosis associated with the use of oral contraceptives (OCs) occurs mostly in the deep veins of the lower extremity. A lesion of the upper extremity is rare, and the majority of thrombotic events that occur in the superficial vein of the upper extremity are caused by intravenous catheters. We present a rare case of superficial venous thrombus on the upper extremity in a woman with a history of long-term OC use. Case presentation: A 35-year-old woman, with an 8-year history of OC use, presented with a 2-year history of painfully palpable masses on her left forearm. The lesion mimicking soft tissue mass was confirmed to be superficial venous thrombi through ultrasound and magnetic resonance imaging. Conservative treatment including non-steroidal anti-inflammatory drugs, vasoprotective agents, and aspirin was prescribed. Through consultation with the Department of Obstetrics and Gynecology, it was confirmed that the current OCs could be discontinued, and the pain was almost relieved after conservative treatment. Conclusions: If thrombotic events occur in the superficial vein of the upper extremity without intravenous catheters, detailed medical history taking and the possibility of OCs should be considered.

Case report: Traumatic median neuropathy in the distal forearm after massage therapy.

Median nerve damage caused by trauma is rare, especially after the massage therapy. There have been no reports of median neuropathy in the distal forearm following massage therapy. A 61-year-old man developed paresthesia and numbness in the right hand after two sessions of massage therapy. Electrophysiologic studies, ultrasound, and magnetic resonance imaging were used to localize and confirm the median nerve lesion in the distal forearm. Ultrasound-guided perineural steroid injection and oral pregabalin were administered. At the 1-month follow-up, more than 80% of the sensory symptoms had resolved, and the results of the sensory nerve conduction study and ultrasound showed improvement. Although massage-induced mononeuropathy is uncommon, massage therapy should be performed carefully to avoid complications.

Changes in hormone levels of participants in a 622-km ultramarathon race based on distance and recovery period.

BACKGROUND: Runners who participate in endurance sports such as marathons or ultramarathons have superior physical capabilities and health benefits compared to others. However, they may suffer long-term effects of the negative physiological changes during long-distance running. This study aimed to examine the effects of an ultramarathon on hormone levels, and the associated risks. METHODS: Ten participants who completed a 622-km ultramarathon were included. Blood was collected prerace, at the 300-km mark, the 622-km mark, and on the 3rd day of recovery (RD3) and the 6th day of recovery (RD6) and analyzed for human growth hormone (HGH), cortisol, beta-endorphin, serotonin, testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH) levels. RESULTS: HGH and beta-endorphin showed the highest increase at the 300-km mark compared to prerace levels, with recovery on RD3 and RD6, respectively. LH, cortisol, and serotonin showed the highest levels of increase at the 622-km mark, with recovery on RD6 for LH, and RD3 for cortisol and serotonin. FSH showed the highest level of decrease at both 300-km and 622-km marks compared to prerace levels, with recovery on RD3. Testosterone decreased the most at the 300-km mark compared to the prerace level and this decrease was below the normal levels; however, it recovered to normal levels on RD3. CONCLUSIONS: Hormone levels after the 622-km ultramarathon were within their normal ranges, except for testosterone. However, all the hormones recovered to prerace levels on RD3 or RD6. This study showed that running ultramarathons does not cause abnormal hormone levels.

Effects of Long-Distance Running on Cardiac Markers and Biomarkers in Exercise-Induced Hypertension Runners: An Observational Study.

OBJECTIVE: To investigate changes of cardiac and muscle damage markers in exercise-induced hypertension (EIH) runners before running (pre-race), immediately after completing a 100-km ultramarathon race, and during the recovery period (24, 72, and 120 hours post-race). METHODS: In this observational study, volunteers were divided into EIH group (n=11) whose maximum systolic blood pressure was ≥210 mmHg in graded exercise testing and normal exercise blood pressure response (NEBPR) group (n=11). Their blood samples were collected at pre-race, immediately after race, and at 24, 72, and 120 hours post-race. RESULTS: Creatine kinase (CK) and cardiac troponin I (cTnI) levels were significantly higher in EIH group than those in the NEBPR group immediately after race and at 24 hours post-race (all p<0.05). However, lactate dehydrogenase (LDH), creatine kinase-myocardial band (CKMB), or CKMB/CK levels did not show any significant differences between the two groups in each period. N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were significantly higher in EIH group than those in NEBPR group immediately after race and at 24 and 72 hours postrace (all p<0.05). A high sensitivity C-reactive protein (hs-CRP) level was significantly higher in EIH group than that in NEBPR group at 24 hours post-race (p<0.05). CONCLUSION: The phenomenon of higher inflammatory and cardiac marker levels in EIH group may exaggerate cardiac volume pressure and blood flow restrictions which in turn can result in cardiac muscle damage. Further prospective studies are needed to investigate the chronic effect of such phenomenon on the cardiovascular system in EIH runners.

Plexiform Neurofibroma of the Posterior Tibial Nerve Misdiagnosed as Proximal Tarsal Tunnel Syndrome: A Case Report.

Plexiform neurofibromas of the foot are rare, benign tumors of the peripheral nerves. Diagnosis can be challenging if they present with symptoms mimicking other peripheral nerve pathologies. Tarsal tunnel syndrome is an entrapment syndrome of the entire tibial nerve behind the medial malleolus and under the flexor retinaculum. The clinical presentation typically includes posteromedial pain, positive Tinel's sign, and neurogenic signs, including both the sensation of numbness and the actual hypoesthesia and clawing of the toes. Here, we report the case of a 59-year-old female patient with plexiform neurofibroma with symptoms similar to those of tarsal tunnel syndrome. The plexiform neurofibroma was surgically excised and the nerve function was partially preserved.

Ultrasound versus fluoroscopy-guided cervical medial branch block for the treatment of chronic cervical facet joint pain: a retrospective comparative study.

OBJECTIVE: To compare the mid-term effects and advantages of the ultrasound (US)-guided with fluoroscopy(FL)-guided cervical medial branch blocks (CMBBs) for chronic cervical facet joint pain through assessment of pain relief, functional improvement, and injection efficiency. METHODS: Patients with chronic cervical facet joint pain who received US- (n = 68) or FL-guided CMBBs (n = 58) were included in this retrospective study. All procedures were performed using a FL or US. The complication frequencies, treatment effects, functional improvement, and injection efficiency of CMBBs were compared at 1, 3, and 6 months after the last injection. RESULTS: Both the NDI and VNS scores showed improvements at 1, 3, and 6 months after the last injection in both groups, with no significant differences between groups (p < 0.05). Furthermore, the treatment success rate at all time points was not significantly different between groups. Logistic regression analysis revealed that the injection method (US- or FL-guided), the number of injections, sex, analgesic use, and age were not independent predictors of treatment success. Compared with FL-guided CMBB, US-guided CMBB was associated with a shorter administration duration and fewer needle passes. CONCLUSIONS: Our results suggest that, compared with FL-guided CMBBs, US-guided CMBBs require a shorter administration duration and fewer needle passes, while providing similar pain relief and functional improvements. Therefore, US-guided CMBBs can be considered as an effective alternative for the conservative management of chronic cervical facet joint pain.

Comparison of Changes in Biochemical Markers for Skeletal Muscles, Hepatic Metabolism, and Renal Function after Three Types of Long-distance Running: Observational Study.

The purpose of this study is to compare changes in biochemical markers for the skeletal muscles, hepatic metabolism, and renal function based on extreme long-distance running.Among healthy amateur endurance athletes who participated in a marathon, 100 km-, or 308 km ultramarathon, 15 athletes with similar physical and demographic characteristics were chosen to be the subjects in this study, upon completion of each course. The subjects' blood was collected before and after the course to identify biochemical markers for the skeletal muscles, hepatic metabolism, and renal function.After all of the courses, creatinine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine transaminase (ALT), blood urea nitrogen (BUN), and creatinine were found to be significantly increased compared with values obtained before the race (P <0.05 for each marker). CK, LDH, AST, and LDH were significantly higher after completion of the 100 km race than the marathon (P <0.05) and were significantly higher after the 308 km race than the marathon or 100 km race (P <0.05). Total protein was significantly lower after the 308 km race than the marathon or 100 km race (P <0.05). Albumin significantly increased after the marathon but significantly decreased after the 308 km course (P <0.05). Total and direct bilirubin were significantly increased after the 100 km and 308 km races (P <0.05), and were significantly higher after the 308 km than the marathon or 100 km course (P <0.05). BUN was significantly higher after the 100 km race than the marathon (P <0.05) and was significantly lower after the 308 km than the 100 km race (P <0.05). Creatinine was significantly higher after the marathon and 100 km than the 308 km race (P <0.05). Uric acid significantly increased after the marathon and 100 km race (P <0.05); it was significantly higher after completing the marathon and 100 km than the 308 km race (P <0.05).Muscular damage, decline in hepatic function, and hemolysis in the blood were higher after running a 308 km race, which is low-intensity running compared with a marathon, and a temporary decline in renal function was higher after completing a 100 km race, which is medium-to-high intensity.

Changes in the markers of cardiac damage in men following long-distance and ultra-long-distance running races.

BACKGROUND: The aim of this study was to compare pre- and postcompetition markers of cardiac damage in ultraendurance athletes. METHODS: All the subjects had blood samples collected before starting and immediately after completing the running race, in order to analyze CK, hs-CRP, cTnI, and NT-proBNP. RESULTS: Before starting the marathon, there were no differences between the groups for all of the tests. CK was significantly higher after the 308 km ultra-marathon than after the marathon and the 100 km ultra-marathon (P<0.001). In cTnI, the value after the 100 km ultra-marathon was significantly higher than that after the marathon and 308 km ultra-marathon, respectively (P<0.05, P<0.01). NT-proBNP was significantly higher after the 100 km and 308 km ultra-marathons than after the marathon (P<0.01, P<0.01). Hs-CRP was significantly higher after the 308 km ultra-marathon than after the marathon and the 100 km ultra-marathon (P<0.001). CONCLUSIONS: cTnI was expressed after marathon and the 100 km ultra-marathon, and NT-proBNP exceeding the upper reference limit (URL) was expressed in long-distance races such as the 100 km and 308 km ultra-marathons. The highest expression of cTnI and NT-proBNP exceeding the URL was in the 100 km ultra-marathon, which may be caused by a combination of the moderate intensity of the exercise and the long-running distance.

Ultrasound-Guided Versus Fluoroscopy-Guided Caudal Epidural Steroid Injection for the Treatment of Unilateral Lower Lumbar Radicular Pain: Case-Controlled, Retrospective, Comparative Study.

The aim of the article is to investigate the efficacy of ultrasound (US)-guided Caudal Epidural Steroid Injection (CESI) compared with fluoroscopy (FL)-guided CESI in patients with unilateral lower lumbar radicular pain. This case-controlled, retrospective, comparative study was done at the university hospital. A total of 110 patients treated with US- or FL-guided CESI were administered a mixture of 20 cc (0.5% lidocaine 18.0  mL + dexamethason 10  mg 2  mL). Outcome measurement was assessed by Oswestry Disability Index (ODI), verbal numeric pain scale (VNS) before injections and at 3, 6, and 12 months after the last injections. Successful outcome was defined as measured by >50% improvement in the VNS score and >40% improvement in the ODI. ODI and VNS showed improvement at 3, 6, and 12 months after the last injection in both groups. No statistical differences in ODI, VNS were observed between groups (P < 0.05). No significant differences in the proportion of patients with successful treatment were observed between the groups from the 3-month to 6-month to 12-month outcomes. US-guided CESI is deserving of consideration in conservative management of unilateral lower lumbar radicular pain.

Ultrasound guided intra-articular ketorolac versus corticosteroid injection in osteoarthritis of the hip: a retrospective comparative study.

OBJECTIVE: Intra-articular steroid injection has been widely used in the management of symptomatic osteoarthritis; however, its frequent use is avoided since there is an increase in the incidence of articular infection and several mechanical side effects such as cartilage breakdown and loss of elasticity of the articular cartilage. For these reasons, nonsteroidal anti-inflammatory drugs instead of corticosteroids can be considered for intra-articular injection. On this basis, we investigated the effects and safety of ultrasound-guided intra-articular ketorolac versus corticosteroid injection for patients with osteoarthritis of the hip. MATERIALS AND METHODS: This retrospective study included 98 patients with diagnoses of hip osteoarthritis who underwent ultrasound-guided intra-articular ketorolac or corticosteroid injection. Fifty patients who received ultrasound-guided intra-articular corticosteroid injection were administered a mixture of 0.5% lidocaine and triamcinolone. Forty-eight patients who received ultrasound-guided intra-articular ketorolac injection were administered 0.5% lidocaine and ketorolac. Outcome measurement was assessed using the Harris hip score and verbal numeric pain scale, which were evaluated before the injections and at 1, 3 and 6 months following the injection. Univariate analysis (using the x (2) test) and multiple logistic regression analysis were performed to evaluate the relationship between the possible outcome predictors (injected medications, patients' age, gender, pain duration and Kellgren-Lawrence classification) and the therapeutic effects. RESULTS: The Harris hip score and verbal numeric pain scale were improved at 1, 3 and 6 months after the injection in both groups. No statistical differences in the Harris hip score and verbal numeric pain scale were observed between the groups. The success rate was also not significantly different among the time periods of 1, 3 and 6 months. Multiple logistic regression and univariate analysis showed that injected medications patients' age, gender, pain duration and Kellgren-Lawrence classification were not independent predictors of successful outcome at midterm follow-up. CONCLUSION: The treatment of osteoarthritis of the hip with intra-articular ketorolac injection is as effective as that with intra-articular corticosteroid injection. Intra-articular ketorolac injection can be considered useful for patients with contraindications to using corticosteroids.

Ultrasound-guided versus fluoroscopy-guided sacroiliac joint intra-articular injections in the noninflammatory sacroiliac joint dysfunction: a prospective, randomized, single-blinded study.

OBJECTIVE: To compare the short-term effects and safety of ultrasound (US)-guided sacroiliac joint (SIJ) injections with fluoroscopy (FL)-guided SIJ injections in patients with noninflammatory SIJ dysfunction. DESIGN: Prospective, randomized controlled trial. SETTING: University hospital. PARTICIPANTS: Patients (N=120) with noninflammatory sacroiliac arthritis were enrolled. INTERVENTION: All procedures were performed using an FL or US apparatus. Subjects were randomly assigned to either the FL or US group. Immediately after the SIJ injections, fluoroscopy was applied to verify the correct placement of the injected medication and intravascular injections. MAIN OUTCOME MEASURES: Treatment effects and functional improvement were compared at 2 and 12 weeks after the procedures. RESULTS: The verbal numeric pain scale and Oswestry Disability Index improved at 2 and 12 weeks after the injections without statistical significances between groups. Of 55 US-guided injections, 48 (87.3%) were successful and 7 (12.7%) were missed. The FL-guided SIJ approach exhibited a greater accuracy (98.2%) than the US-guided approach. Vascularization around the SIJ was seen in 34 of 55 patients. Among the 34 patients, 7 had vascularization inside the joint, 23 had vascularization around the joint, and 4 had vascularization both inside and around the joint. Three cases of intravascular injections occurred in the FL group. CONCLUSIONS: The US-guided approach may facilitate the identification and avoidance of the critical vessels around or within the SIJ. Function and pain relief significantly improved in both groups without significant differences between groups. The US-guided approach was shown to be as effective as the FL-guided approach in treatment effects. However, diagnostic application in the SIJ may be limited because of the significantly lower accuracy rate (87.3%).

Palpation versus ultrasound-guided corticosteroid injections and short-term effect in the distal radioulnar joint disorder: a randomized, prospective single-blinded study.

The aim of this study was to conduct a randomized, prospective single-blinded clinical study on the mid-term benefits and accuracy rate of the ultrasound (US)-guided versus palpation-guided intra-articular (IA) injections for the treatment of distal radioulnar joint (DRUJ) disorder. Subjects with DRUJ disorder (n = 60) were randomly assigned to undergo US-guided or palpation-guided IA injection. Primary outcomes were measured with Disability of the Arm, Shoulder, and Hand questionnaire (DASH) and secondary outcomes included Verbal Numeric Pain Scale (VNS), Modified Mayo Wrist Score (MMWS), range of motion (ROM), and accuracy rate between two groups; 1.25 mL of mixed material (0.5 ml Omnipaque + 1 % lidocaine 0.25 ml + triamcinolone 20 mg 0.5 ml) was injected into the intra-articular space of the DRUJ. Treatment effects were assessed by using VNS, DASH, MMWS, and passive ROM of the DRUJ (supination, pronation from neutral) before the injections and at 1, 3, and 6 months after the injections. After the US-guided and palpation-guided IA injection into DRUJ, a radiographic image was taken to determine whether the injected material had reached the IA space or infiltrated into the soft tissue. US-guided IA injections showed significantly higher accuracy (100 %) than palpation-guided IA injections (75.8 %) in DRUJ. VNS, DASH, MMWS, and ROM were improved at 1, 3, and 6 months in both groups. There was no significant difference in clinical outcomes between the group receiving US-guided injections and the group receiving palpation-guided injections. US-guided IA injection showed significantly higher accuracy than palpation-guided IA injection in the DRUJ, and corticosteroid IA injections were effective in improving of the pain of patients with DRUJ disorder during 6 months of follow-up.

Ultrasound versus palpation guidance for intra-articular injections in patients with degenerative osteoarthritis of the elbow.

OBJECTIVES: The aim of this study is to evaluate the accuracy rate of ultrasound (US) -guided intra-articular (IA) injections in patients by posterior approach with osteoarthritis (OA) of the elbow. METHODS: Eighty patients with physical examination and radiographic findings of elbow OA were included. After US-guided IA or palpation-guided IA injection of iohexol contrast by posterior approach into the elbow joint, fluoroscopic images were obtained to ascertain whether the injected material had reached the IA space. RESULTS: Of the 40 injections performed by US guidance, 40 were confirmed to have been placed in the IA space (an accuracy rate of 100%). Thirty-one of the 40 injections performed by the palpation guidance were IA space (77.5% accuracy rate). CONCLUSIONS: US-guided IA elbow injections by posterior approach may raise the accuracy rate in elbow joint injections.

Acupuncture sensation during ultrasound guided acupuncture needling.

BACKGROUND: Although acupuncture sensation (also known as de qi) is a cornerstone of traditional acupuncture therapy, most research has accepted the traditional method of defining acupuncture sensation only through subjective patient reports rather than on any quantifiable physiological basis. PURPOSE: To preliminarily investigate the frequency of key sensations experienced while needling to specific, quantifiable tissue levels (TLs) guided by ultrasound (US) imaging. METHODS: Five participants received needling at two acupuncture points and two control points at four TLs. US scans were used to determine when each TL was reached. Each volunteer completed 32 sets of modified Southampton Needle Sensation Questionnaires. Part one of the study tested sensations experienced at each TL and part two compared the effect of oscillation alone versus oscillation+rotation. RESULTS: In all volunteers, the frequency of pricking, sharp sensations was significantly greater in shallower TLs than deeper (p=0.007); the frequency of sensations described as deep, dull and heavy, as spreading, and as electric shocks was significantly greater in deeper TLs than shallower (p=0.002). Sensations experienced did not significantly differ between real and control points within each of three TLs (p>0.05) except TL 4 (p=0.006). The introduction of needle rotation significantly increased deep, dull, heavy sensations, but not pricking and sharp sensations; within each level, the spectrum of sensation experienced during both oscillation+rotation and oscillation alone did not significantly differ between acupuncture and control points. CONCLUSION: The preliminary study indicates a strong connection between acupuncture sensation and both tissue depth and needle rotation. Furthermore, the new methodology has been proven feasible. A further study with an objective measurement is warranted.

Effect of cardiac rehabilitation and statin treatment on anti-HSP antibody titers in patients with coronary artery disease after percutaneous coronary intervention.

Accumulating evidence suggests that higher antibody titers to heat shock proteins (HSPs) are associated with the development and severity of atherosclerosis. The aim of this study was to evaluate the impact of cardiac rehabilitation therapy (CRT) or stain treatment (STT) or a combination of both (COM) on anti-HSP antibodies in patients with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). Clinical evaluation of subjects was performed both at the commencement and completion of the 14 weeks of treatment. CRT consisted of a supervised 6 weeks of exercise following hospital discharge and 8 weeks of home stay exercise. Patients assigned to statin therapy were treated with 80 mg per day of fluvastatin. Blood samples from 39 patients were analyzed for antibodies to HSP60 and HSP70 by ELISA. Biochemical parameters, including lipids, high-sensitivity C reactive protein (hsCRP), and interleukin-6 (IL-6), were also analyzed. We found that CRT and COM reduced antibody titers to HSP60 and HSP70 in CAD patients (by 3.79 and 10.00% of anti-HSP60, and by 5.74 and 3.45% of anti-HSP70, respectively) but statin treatment reduced only antibody titers to HSP70 (by 3.83%). There was a significant correlation between antibody titers to HSP60 versus HSP70. Considering the fact that antibody titers to HSPs are associated with the autoimmune process in CAD, CRT and COM have greater effects on reduction in autoimmune reaction after PCI than statin treatment. This reduction was accompanied by greater improvements in blood biochemical variables, such as lipids, hsCRP, and IL-6 after CRT and COM.
