PURPOSE: Changes in serum biomarkers of cardiac and muscle damage have been studied in ultra-marathon runners for distances up to 308 km. We investigated these biomarker changes following a 622-km super-ultramarathon race. METHODS: A group of men with a mean age of 52.7±4.8 years participated. Blood samples were obtained pre-race, during the race, and post-race, to analyze the aforementioned biomarkers. RESULTS: Creatine kinase and creatine kinase-MB (CK-MB) levels increased during the race, and both steadily declined post-race with CK-MB declining at a slower rate. Lactic acid dehydrogenase levels overall were increased over pre-race levels. White blood cell counts increased during the race. Red blood cell decreased from pre-race to 300 km and 622 km. Platelet increased only in the recovery period. High-sensitivity C-reactive protein levels were increased throughout the race and at day 3 compared to pre-race levels. Cardiac troponin I (cTnI) levels increased during the race. N-terminal pro b-type natriuretic peptide (NT-proBNP) levels increased during the race. CONCLUSION: The rise in cTnI was not clinically significant, and highly elevated NT-proBNP levels during the race indicates that myocardial burden rose linearly as running distance increased. However, no clinical risk was found as most of the markers returned to normal range during the recovery.

OBJECTIVE: To compare the short-term effects and advantages of transforaminal epidural steroid injection (TFESI) performed using the conventional (CL) and posterolateral (PL) approaches. METHOD: Fifty patients with lumbar radicular pain from lumbar spinal stenosis and herniated lumbar disc were enrolled. Subjects were randomly assigned to one of two groups (CL or PL group). All procedures were performed using a C-arm (KMC 950, KOMED, Kwangju, Kyunggi, Korea). We compared the frequency of complications during the procedure and the effects of the pain block between the two groups at 2, 4, and 12 weeks after the procedure. RESULTS: There were no significant differences in the demographic data, initial VNS (Visual numeric scale), or ODI (Oswestry disability index) between the CL group (n=26) and the PL group (n=24). There was no statistically significant difference in the outcome measures (VNS and ODI) between the groups at 2, 4, or 12 weeks. Symptoms of nerve root irritation occurred in 1 case of the CL group and in 7 cases of the PL group (p<0.05). Pricking of spinal nerve during the procedure and transient weakness after the procedure occurred in 6 cases and 3 cases, respectively in the CL group, but did not occur in the PL group. CONCLUSION: Our findings suggest that the posterolateral approach represents an alternative TFESI method in cases with difficult needle tip positioning in the anterior epidural space, and could lower the risk of target nerve root irritation and nerve penetration.

OBJECTIVE: To compare to type and size of rotator cuff tear (RCT) in the transverse view before and after arthro-3D sonography. METHOD: Total 24 cases with rotator cuff tear were diagnosed according to ultrasonographic finding. All of patients were performed by a posterior-lateral approach for sono-guided intra-articular injection and underwent by both before and after arthro 3D sonogrpahy. We measured size (transverse, longitudinal, area) of RCT on the transverse scan in search of the largest lesion and the difference to type and size of RCT after arthrography. RESULTS: 3D ultrasonography detected full-thickness tear in 18 cases, partial-thickness tear in 6 cases before arthro-3D sonograhy. Change in the diagnosis of rotator cuff tear after arthro-3D sonogrphy; 3 partial-thickness tear were diagnosed as full-thickness tear. The size (transverse, longitudinal, area) of RCT was increased significantly after arthro-3D sonography compared with that before arthro 3D sonography. CONCLUSION: Arthro-3D sonography is useful for evaluation the configuration of RCT. Using this method, we can provide the objective and steric image of RCT.

OBJECTIVE: To investigate the sonographic appearance of plantar fibromatosis in Korean adults, thus enabling sonographic diagnosis of the benign, focally invasive fibrous neoplasm. METHOD: The medical records, pathologic reports, and sonographic reports and image of 42 patient with plantar fibromatosis were reviewed retrospectively. RESULTS: US demonstrated plantar fibromatosis as a fusiform nodular thickening of the plantar fascia oriented according to its major axis. A total of 60 fibromatosis nodules in 42 patient were examined. Thirty-eight (63.33%) of the 60 were elongated. The remaing 22 were rounded or oval. Thirty-five (58.33%) were hypoechoic; fivty-one (85%) were 20 mm long or less. Eight of 9 lesions that had mixed echogenicity were longer than 20 mm. CONCLUSION: Our results suggest that the lesions of the plantar fibromatosis were characteristically located on the surface of the plantar fascia, longitudinally elongated, most often less than 20 mm long, fusiform and hypoechoic. Lesions longer than 10 mm often exhibited mixed echogenicity. Our sonographic finding was helpful in diagnosing planatar fibromatosis in the Korean.

The facet joints are a common source of chronic spinal pain. Blocks of the nerves supplying the facet joints are validated tools in the diagnosis and treatment for facet joint pain. These interventions are typically performed with fluoroscopic guidance. However, the target, which is the nerve, is radiolucent and cannot be identified with fluoroscopy. Recently, several ultrasound guided techniques in the domain of spinal pain have been emerging because ultrasound is useful in visualization of the inner structures, is portable, and is not associated with the radiation exposure. This paper reviews a variety of techniques for ultrasound guided interventions for the medial branch block which has been reported in treating axial pain originating from the facet joint.

Shoulder pain is one of the common symptoms that pain physicians frequently encounter in outpatient settings. Historically, the diagnosis of shoulder pain relied on clinical presentation and physical examination. However, with the advancement of ultrasound technology, physicians can now better diagnose and treat shoulder pain. When administering injection therapy for shoulder pain, the target may vary depending on the structure causing the pain. Furthermore, even when injecting the same structure, different approaches can be employed based on the practitioner’s preference, patient’s anatomical variations, or capability of maintaining specific positions for intervention. This review describes various ultrasound-guided injection techniques used in the treatment of shoulder pain.

Hereditary hemolytic anemia comprises a group of disorders in which red blood cells are destroyed faster than they are produced in the bone marrow; various hereditary factors can cause this condition, including production of defective Hb and erythrocyte membrane. Recently, we identified Hb Koriyama, a rare Hb variant that was undetectable in Hb electrophoresis and stability tests, in a patient with severe hemolytic anemia. This is the first study to show the nucleotide-level sequence variations in Hb Koriyama. On the basis of our results, we conclude that unstable Hb may not be detectable by conventional Hb electrophoresis or stability tests. Thus, we suggest further genetic workup in cases of unexplained hereditary hemolytic anemia.

OBJECTIVE: To identify the volumes of contrast material needed to reach the specific landmarks and contrast pattern during Kambin's triangle approach (KB-A) in lumbar spinal stenosis. METHOD: Sixty patients undergoing KB-A were investigated. Fifty-six patients were included in this study. KB-A were performed with the use of contrast-enhanced fluoroscopic visualization. After confirming the appropriate spinal needle position, a slow injection of up to 5.0 ml of nonionic contrast material was carried out. Under intermittent fluoroscopic guidance, contrast volumes were recorded as flow reached specific anatomic landmarks: ipsilateral inferior or superior neural foramen. RESULTS: After 2.0 ml of contrast was injected, 93.2% of KB-A cases spread to the medial aspect of the inferior pedicle of the corresponding level of injection and 86.3% of KB-A spread to the medial aspect of the superior pedicle of the corresponding level of injection. After 3 ml of contrast was injected, 95.3% of KB-A spread to cover both the medial aspect of the inferior pedicle and the superior pedicle of the corresponding level of injection. A volume of 2 ml of injectate reaches the anterior epidural space 100% of the time. CONCLUSION: This study demonstrates injectate volumes needed to reach the specific anatomic landmarks in KB-A. A volume of 3.0 ml of injectate reaches both the medial aspect of theinferior pedicle and the superior pedicle 94.6% of the time. Therefore, Interventionalists may consider a 1-level instead of a 2-level injection for patients with a bleeding risk or for 2 level central pathology.

OBJECTIVE: To compare the short-term effect and advantage of transforaminal epidural steroid injection (TFESI) performed using the Kambin's triangle and subpedicular approaches. METHOD: Forty-two patients with radicular pain from lumbar spinal stenosis were enrolled. Subjects were randomly assigned to one of two groups. All procedures were performed using C-arm KMC 950. The frequency of complications during the procedure and the effect of TFESI at 2 and 4 weeks after the procedure between the two groups were compared. Short-term outcomes were measured using a visual numeric scale (VNS) and a five-grade scale. Multiple logistic regression analyses were performed to evaluate the relationship between possible outcome predictors (Kambin's triangle or subpedicular approach, age, duration of symptoms and sex) and the therapeutic effect. RESULTS: VNS was improved 2 weeks after the injection and continued to improve until 4 weeks in both groups. There were no statistical differences in changes of VNS, effectiveness and contrast spread pattern between these two groups. No correlation was found between the other variables tested and therapeutic effect. Spinal nerve pricking occurred in five cases of the subpedicular and in none of the cases of the Kambin's triangle approach (p<0.05). CONCLUSION: The Kambin's triangle approach is as efficacious as the subpedicular approach for short-term effect and offers considerable advantages (i.e., less spinal nerve pricking during procedure). The Kambin's triangle approach maybe an alternative method for transforaminal epidural steroid injection in cases where needle tip positioning in the anterior epidural space is difficult.

OBJECTIVE: To investigate the efficacy of percutaneous adhesiolysis (PA) compared to fluoroscopy (FL)-guided transforaminal epidural steroid injection (TFESI) in patients with radicular pain caused by lumbar foraminal spinal stenosis (LFSS) by assessing pain relief and functional improvement at 4 and 12 weeks post-procedure. METHODS: This retrospective study included 45 patients who underwent PA or FL-guided TFSEI for radicular pain caused by LFSS of at least 3 months' duration. Outcomes were assessed with the Oswestry Disability Index (ODI) and Verbal Numeric Pain Scale (VNS) before the procedure and at 4 and 12 weeks post-procedure. A successful outcome was defined by >50% improvement in the VNS score and >40% improvement in the ODI score. RESULTS: ODI and VNS scores improved 4 and 12 weeks post-procedure in both groups. Statistically significant differences between groups were observed in ODI and VNS at 12 weeks (p<0.05). The proportion of patients with successful outcomes was significantly different between the two groups only at the 12-week time point. CONCLUSION: Our study suggests that PA is effective for pain reduction and functional improvement in patients with chronic radicular pain caused by LFSS. Therefore, PA can be considered for patients with previous ineffective responses to conservative treatment. Although PA seems to be more effective than TFEFI according to the results of our study, in order to fully elucidate the difference in effectiveness, a prospective study with a larger sample size is necessary.
