    Title: The effect of intra-articular stimulation by pulsed radiofrequency on chronic sacroiliac joint pain refractory to intra-articular corticosteroid injection: A retrospective study
    Author: Chang, Min Cheol; Ahn, Sang Ho
    Subject: Pulsed Radiofrequency Treatment ; Chronic Pain -- Therapy ; Low Back Pain -- Therapy
    Description: We investigated the degree of pain reduction following intra-articular (IA) pulsed radiofrequency (PRF) stimulation of the sacroiliac joint (SIJ) in patients with chronic SIJ pain that had not responded to IA corticosteroid injection. Twenty patients were recruited. Clinical outcomes after applying PRF stimulation of the SIJ were evaluated by a numeric rating scale (NRS) and a 7-point Likert scale. The NRS scores significantly changed over time. The NRS scores at 1, 2, and 3 months after PRF were significantly lower than those before PRF. However, 4 of the 20 patients (20%) reported successful pain relief (pain relief of ≥ 50%) and were satisfied with the PRF stimulation at 3 months after treatment. IA PRF stimulation of the SIJ was not successful in most patients (80% of all patients). Based on our results, we cannot recommend this procedure to patients with chronic SIJ pain that was unresponsive to IA SIJ corticosteroid injection. Further studies on the effective mode of PRF stimulation...

    Title: Two-Year Outcome of Percutaneous Bipolar Radiofrequency Neurotomy of Sacral Nerves S2 and S3 in Spinal Cord Injured Patients with Neurogenic Detrusor Overactivity: A Randomized Controlled Feasibility Study
    Author: Jo, Hae Min; Kim, Hyo Sung; Cho, Yun-Woo; Ahn, Sang-Ho
    Subject: Catheter Ablation ; Spinal Cord Injuries -- Therapy
    Description: Little research has been expended on the use of bipolar radiofrequency (RF) lesioning of sacral nerves in spinal cord injured (SCI) patients with neurogenic detrusor overactivity (NDO), and no study has been undertaken to demonstrate its long-term effect. To investigated the effect of bipolar RF ablation of the second and third sacral nerves over 2 years in SCI patients with NDO. A prospective, randomized controlled feasibility study. The outpatient clinic of a single academic medical center in Korea. Ten SCI patients with NDO were recruited. These patients were randomly assigned to 2 groups; the intervention group (n = 5) and the control group (n = 5). Control group members received optimized conventional treatment. International Consultation on Incontinence Questionnaire (ICIQ), 3-day voiding diary, and the urinary incontinence quality of life scale (I-QOL) data were obtained at baseline and at 6, 12, and 24 months after intervention. Urodynamic study (UDS) was performed at baseline and 24 months after intervention. In the intervention group, percutaneous bipolar RF neurotomy was performed on both S2 and S3 nerves in each patient. Frequency of urinary incontinence and ICIQ and IQOL scores showed significant effects for time and for the group x time interaction (P < 0.05). Daily mean volume of urinary incontinence showed only a significant group effect. In UDS parameters, comparisons of values at baseline and at 24 months revealed all variables showed significant intergroup differences (P < 0.05). A small number of patients was recruited. Percutaneous bipolar RF ablation of sacral nerves S2 and S3 effectively reduces urinary incontinence and improves quality of life (QoL) in SCI patients with NDO and the effects lasted over 2 years.

    Title: Comparison of intra-articular lumbar facet joint pulsed radiofrequency and intra-articular lumbar facet joint corticosteroid injection for management of lumbar facet joint pain: A randomized controlled trial
    Author: Do, Kyung Hee; Ahn, Sang Ho; Cho, Yun Woo; Chang, Min Cheol
    Subject: Pulsed Radiofrequency Treatment ; Zygapophyseal Joint ; Adrenal Cortex Hormones -- Administration & Dosage ; Low Back Pain -- Therapy
    Description: This study aimed to demonstrate the effect of intra-articular (IA) lumbar facet joint (LFJ) pulsed radiofrequency (PRF) for the management of LFJ pain, and to compare the effect of IA LFJ PRF to IA corticosteroid injection (ICI). Pathology in the LFJ is a common source of lower back pain (LBP). It is responsible for chronic LBP in approximately 15% to 45% of patients. It has been reported that PRF stimulation can effectively reduce refractory joint pain. Sixty patients with LFJ pain were recruited and randomly assigned to 1 of 2 groups: the IA PRF group and the ICI group. There were 30 patients in each group. At pretreatment, 2 weeks, 1, 3, and 6 months after treatment, we assessed the severity of LBP using a numeric rating scale (NRS). Compared with the pretreatment NRS scores, patients in both groups showed a significant decrease in NRS scores at 2 weeks, and 1, 3, and 6 months after each treatment. Between groups, changes in the NRS scores were significantly different over time. At 2 weeks and 1 month after each procedure, the NRS score after ICI was significantly lower than that after the PRF stimulation. However, at 3 and 6 months after the procedures, the decrements of NRS scores were not significantly different between the 2 groups. Six months after treatment, about half of patients in both groups reported successful pain relief (pain relief of ≥50%). In the current study, both IA PRF stimulation and ICI into the LFJ significantly relieved LFJ pain. Their effects persisted for at least 6 months after the procedure. Thus, IA PRF is a useful therapeutic option for the management of LFJ pain.

    Title: Non-structural protein 1 of influenza viruses inhibits rapid mRNA degradation mediated by double-stranded RNA-binding protein, staufen1
    Author: Cho, Hana; Ahn, Sang Ho; Kim, Kyoung Mi; Kim, Yoon Ki
    Subject: Nonsense Mediated Mrna Decay ; Cytoskeletal Proteins -- Metabolism ; Orthomyxoviridae -- Physiology ; RNA, Messenger -- Metabolism ; RNA-Binding Proteins -- Metabolism ; Viral Nonstructural Proteins -- Metabolism
    Description: Although non-structural protein 1 (NS1) of influenza viruses is not essential for virulence, this protein is involved in host-virus interactions, viral replication, and translation. In particular, NS1 is known to interact with the host protein, staufen1 (Stau1). This interaction is important for efficient viral replication. However, the underlying molecular mechanism by which NS1 influences the viral life cycle remains obscure. Here, we show using immunoprecipitation and artificial tethering that the N-terminus of NS1, NS1(1-73), interacts with Stau1, blocks the Stau1-Upf1 interaction, and consequently inhibits the efficiency of Stau1-mediated mRNA decay (SMD), but not nonsense-mediatedmRNA decay (NMD). The regulation of SMD efficiency by NS1 may contribute to building a more favorable cellular environment for viral replication.

    Subject: Back Pain -- Therapy ; Pain Management -- Methods ; Pulsed Radiofrequency Treatment -- Methods ; Radiculopathy -- Therapy
    Description: Patients with lumbosacral radicular pain may complain of persisting pain after monopolar pulsed radiofrequency (PRF) treatment. We evaluated the effect of bipolar PRF stimulation of the dorsal root ganglion (DRG) in patients with chronic lumbosacral radicular pain who were unresponsive to both monopolar PRF stimulation of the DRG and transforaminal epidural steroid injection (TFESI). This is a prospective observational study. The outpatient clinic of a single academic medical center in Korea. We retrospectively reviewed data from 102 patients who had received monopolar PRF to the DRG for management of lumbosacral radiculopathy. Of these, 32 patients had persistent radicular pain that was scored at least 5 on a numeric rating scale (NRS). Twenty-three of them were included in this study and underwent bipolar PRF of the DRG. The outcomes after the procedure were evaluated using the NRS for radicular pain before treatment and 1, 2, and 3 months after treatment. Successful pain relief was defined as >/= 50% reduction in the NRS score compared with the score prior to treatment. Furthermore, at 3 months after treatment, patient satisfaction levels were examined. Patients reporting very good (score = 7) or good results (score = 6) were considered to be satisfied with the procedure. The NRS scores changed significantly over time. At 1, 2, and 3 months after bipolar PRF, the NRS scores were significantly reduced compared with the scores before the treatment. Twelve (52.2%) of the 23 patients reported successful pain relief and were satisfied with treatment results 3 months after bipolar PRF. No serious adverse effects were recorded. A small number of patients were recruited and we did not perform long-term follow-up. We believe the use of bipolar PRF of the DRG can be an effective and safe interventional technique for chronic refractory lumbosacral radiculopathy. It appears to be a potential option that can be tried before proceeding to spinal surgery.
