Abstract Title: Ultrasound plus low-level laser therapy for knee osteoarthritis rehabilitation: a randomized, placebo-controlled trial. Abstract Source: Rheumatol Int. 2018 Feb 26. Epub 2018 Feb 26. PMID: 29480363 Abstract Author(s): Fernanda Rossi Paolillo, Alessandra Rossi Paolillo, Jessica Patrícia João, Daniele Frascá, Marcelo Duchêne, Herbert Alexandre João, Vanderlei Salvador Bagnato Article Affiliation: Fernanda Rossi Paolillo Abstract: This study evaluated the synergistic effects of ultrasound (US) and low-level laser therapy (LLLT) with or without therapeutic exercises (TE) in women with knee osteoarthritis. Forty-two Caucasian women with knee osteoarthritis were allocated into three groups: (1) the placebo group who did not perform TE, but the prototype without emitting light or ultrasonic waves was applied, (2) the US + LLLT group in which only the prototype was applied and (3) the TE + US + LLLT group that performed TE before the prototype was applied. However, 35 women completed the full clinical trial. Pressure pain thresholds (PPT) using an algometer and functional performance during the sit-to-stand test were carried out. The average PPT levels increased for US + LLLT (41 ± 9 to 54 ± 15 N, p < 0.01) and TE + US + LLLT (32 ± 8 to 45 ± 9 N, p < 0.01) groups. The number of sit-to-stands was significantly higher for all groups. However, the change between pre-treatment and post-treatment (delta value) was greater for the US + LLLT (4 ± 1) and TE + US + LLLT groups (5 ± 1) than for the placebo group (2 ± 1) witha significant intergroup difference (p < 0.05). This study showed reduced pain and increased physical functionality after 3 months of US + LLLT with and without TE. Article Published Date : Feb 25, 2018

Abstract Title: Combinational light emitting diode-high frequency focused ultrasound treatment for HeLa cell. Abstract Source: Comput Assist Surg (Abingdon). 2017 Sep 28:1-7. Epub 2017 Sep 28. PMID: 28956464 Abstract Author(s): Se-Woon Choe, Kitae Park, Chulwoo Park, Jaemyung Ryu, Hojong Choi Article Affiliation: Se-Woon Choe Abstract: PURPOSE: Light sources such as laser and light emitting diode or ultrasound devices have been widely used for cancer therapy and regenerative medicines, since they are more cost-effective and less harmful than radiation therapy, chemotherapy or magnetic treatment. Compared to laser and low intensity ultrasound techniques, light emitting diode and high frequency focused ultrasound shows enhanced therapeutic effects, especially for small tumors. MATERIALS AND METHODS: We propose combinational light emitting diode-high frequency focused ultrasound treatment for human cervical cancer HeLa cells. Individual red, green, and blue light emitting diode light only, high frequency focused ultrasound only, or light emitting diode light combined with high frequency focused ultrasound treatments were applied in order to characterize the responses of HeLa cells. RESULTS: Cell density exposed by blue light emitting diode light combined with high frequency focused ultrasound (2.19 ± 0.58%) was much lower than that of cells exposed by red and green light emitting diode lights (81.71 ± 9.92% and 61.81 ± 4.09%), blue light emitting diode light (11.19 ± 2.51%) or high frequency focused ultrasound only (9.72 ± 1.04%). CONCLUSIONS: We believe that the proposed combinational blue light emitting diode-high frequency focused ultrasound treatment could have therapeutic benefits to alleviate cancer cell proliferation.

We assessed the efficacy of ultrasound therapy on nodules associated with first-line treatments in multiple sclerosis patients. MATERIALS AND METHODS: Twenty-two multiple sclerosis patients were enrolled during 2013 and randomized to two groups: in the control group patients were treated only with a conventional gel prescribed for cellulite and nodules, while in the experimental group the gel was combined with ultrasound therapy. Patients were treated during 10 weeks and followed up for 10 additional weeks. Three nodules were assessed for each patient, measuring size, pain and redness at 0, 10 and 20 weeks. RESULTS: We found a significant decrease in both groups in size, pain and redness across the three visits (p<0.0001 for size, p = 0.01 and p<0.0001 for pain, and p = 0.0002 and p<0.0001 for redness, respectively for the difference at visit 2 and 3 with respect to visit 1). More interestingly, we observed a greater reduction in pain and redness in the ultrasound-treated group, but the difference was only statistically significant at 10 weeks (p = 0.01 for both pain and redness). On the third visit, no differences between control and experimental groups were detected, both achieving the same levels in measured variables. CONCLUSIONS: Both treatments are useful to improve skin reaction after first-line treatments, but ultrasound in combination with gel achieves a faster reduction in pain and redness, suggesting that ultrasound treatment might be a good analgesic for nodule management in multiple sclerosis patients.

Abstract Title: Focused ultrasound-aided immunomodulation in glioblastoma multiforme: a therapeutic concept. Abstract Source: J Ther Ultrasound. 2016 ;4:2. Epub 2016 Jan 22. PMID: 26807257 Abstract Author(s): Or Cohen-Inbar, Zhiyuan Xu, Jason P Sheehan Article Affiliation: Or Cohen-Inbar Abstract: Patients with glioblastoma multiforme (GBM) exhibit a deficient anti-tumor immune response. Both arms of the immune system were shown to be hampered in GBM, namely the local cellular immunity mediated by the Th1 subset of helper T cells and the systemic humoral immunity mediated by the Th2 subset of helper T cells. Immunotherapy is rapidly becoming one of the pillars of anti-cancer therapy. GBM has not received similar clinical successes as of yet, which may be attributed to its relative inaccessibility (the blood-brain barrier (BBB)), its poor immunogenicity, few characterized cancer antigens, or any of the many other immune mechanisms known to be hampered. Focused ultrasound (FUS) is emerging as a promising treatment approach. The effects of FUS on the tissue are not merely thermal. Mounting evidence suggests that in addition to thermal ablation, FUS induces mechanical acoustic cavitation and immunomodulation plays a key role in boosting the host anti-tumor immune responses. We separately discuss the different pertinent immunosuppressive mechanisms harnessed by GBM and the immunomodulatory effects of FUS. The effect of FUS and microbubbles in disrupting the BBB and introducing antigens and drugs to the tumor milieu is discussed. The FUS-induced pro-inflammatory cytokines secretion and stress response, the FUS-induced change in the intra-tumoral immune-cells populations, the FUS-induced augmentation of dendritic cells activity, and the FUS-induced increased cytotoxic cells potency are all discussed. We next attempt at offering a conceptual synopsis of the synergistic treatment of GBM utilizing FUS and immunotherapy. In conclusion, it is increasingly apparent that no single treatment modality will triumph on GBM. The reviewed FUS-induced immunomodulation effects can be harnessed to current and developing immunotherapy approaches. Together, these may overcome GBM-induced immune-evasion and generate a clinically relevant anti-tumor immune response. Article Published Date : Dec 31, 2015

Abstract Title: Combined ultrasound-curcumin treatment of human cervical cancer cells. Abstract Source: Eur J Obstet Gynecol Reprod Biol. 2015 Aug 1 ;193:96-101. Epub 2015 Aug 1. PMID: 26262768 Abstract Author(s): Kaylene R Carr, Yevgeniya J Ioffe, Maria Filippova, Penelope Duerksen-Hughes, Philip J Chan Article Affiliation: Kaylene R Carr Abstract: OBJECTIVES: Human papillomavirus (HPV) is associated with cervical cancer. Studies showed curcumin inhibits HPV oncogenes expression but curcumin has low bioavailability. The objectives were: (1) to study ultrasound enhancement of curcumin effects on HeLa, SiHa and C33A, (2) to compare two frequencies for sonoporation and (3) to detect cell-free DNA released by the treatment. STUDY DESIGN: HeLa, SiHa and C33A cells (non-HPV control) were processed and exposed to either: (1) 10μM curcumin only, (2) 10μM curcumin with 8s of 7.5MHz ultrasound, (3) 10μM curcumin with 8s of 5.0MHz ultrasound, (4) control medium, or (5) 8s of 7.5MHz ultrasound. The five treated groups were incubated (48h) and analyzed by dual fluorescence apoptosis/necrosis assay. DNA in spent media was analyzed by capillary analysis. RESULTS: Combined curcumin ultrasound resulted in 9-, 12- and 16-fold higher necrosis in HeLa, SiHa and C33A cells respectively. Increased necrosis correlated with higher ultrasound frequencies. There was increased apoptosis in HeLa or SiHa cells with the combined treatment. Curcumin alone resulted in a lesser 2-4-fold increase in necrosis in the groups. Cell-free DNA was detected in the spent media of HeLa and SiHa but not C33A cultures. CONCLUSIONS: The results showed enhanced necrosis in cervical carcinoma cell lines after combined treatment and confirmed the ultrasound capacity to increase effectiveness of curcumin. Cancer cells were smaller post-treatment suggesting microtubule structural disruption. Cell-free DNA was low molecular weight consistent with lysed host cell. Article Published Date : Jul 31, 2015

Abstract Title: Low intensity-pulsed ultrasound induced apoptosis of human hepatocellular carcinoma cells in vitro. Abstract Source: Ultrasonics. 2015 Jul 26. Epub 2015 Jul 26. PMID: 26231998 Abstract Author(s): Mingfang Shi, Bangzhong Liu, Guanghua Liu, Ping Wang, Mingzhen Yang, Yun Li, Jian Zhou Article Affiliation: Mingfang Shi Abstract: The present study was conducted to determine whether low intensity-pulsed ultrasound (LIPUS) could induce apoptosis of human hepatocellular carcinoma cells, SMMC-7721, and to define the mechanism of ultrasound-induced apoptosis, in vitro. MTT assay was used to measure cell proliferation. Apoptosis was investigated by multiple methods such as flow cytometry, DNA fragmentation, Ca(2+) mobilizations, pro- and anti-apoptotic protein expression, and light as well as ultramicroscopic morphology. The results provide evidence that LIPUS induced a dose-dependent effect on cell viability and apoptosis of SMMC-7721 cells. Specifically, exposure of cells to>0.5W/cm(2) intensity significantly increased cell apoptosis, caused shifts in cell cycle phase, and induced structural changes. Ultrasound significantly increased intracellular Ca(2+) concentrations and modulated expression of caspase-3, Bcl-2 and Bax. The findings suggest that this novel technology can be used to induce SMMC-7721 apoptosis via the Ca(2+)/mitochondrial pathway and could potentially be of clinical use for the treatment of hepatocellular carcinoma (SMMC-7721 cell line) and other cancers.

Abstract Title: Ultrasonic Stimulation of Mouse Skin Reverses the Healing Delays in Diabetes and Aging by Activation of Rac1. Abstract Source: J Invest Dermatol. 2015 Jun 16. Epub 2015 Jun 16. PMID: 26079528 Abstract Author(s): James A Roper, Rosalind C Williamson, Blandine Bally, Christopher Am Cowell, Rebecca Brooks, Phil Stephens, Andrew J Harrison, Mark D Bass Article Affiliation: James A Roper Abstract: Chronic skin healing defects are one of the leading challenges to lifelong wellbeing, affecting 2-5% of populations. Chronic wound formation is linked to age and diabetes and frequently leads to major limb amputation. Here we identify a strategy to reverse fibroblast senescence and improve healing rates. In healthy skin, fibronectin activates Rac1 in fibroblasts, causing migration into the wound bed and driving wound contraction. We discover that mechanical stimulation of skin with ultrasound can overturn healing defects by activating a calcium/CamKinaseII/Tiam1/Rac1 pathway that substitutes for fibronectin-dependent signaling and promotes fibroblast migration. Treatment of diabetic and aged mice recruits fibroblasts to the wound bed and reduces healing times by 30%, restoring healing rates to those observed in young, healthy animals. Ultrasound treatment is equally effective in rescuing the healing defects of animals lacking fibronectin receptors, and can be blocked by pharmacological inhibition of the CamKinaseII pathway. Finally, we discover that the migration defects of fibroblasts from human venous leg ulcer patients can be reversed by ultrasound, demonstrating that the approach is applicable to human chronic samples. By demonstrating that this alternative Rac1 pathway can substitute for that normally operating in skin, we identify future opportunities for management of chronic wounds.Journal of Investigative Dermatology accepted article preview online, 16 June 2015. doi:10.1038/jid.2015.224.

Abstract Title: Low-intensity pulsed ultrasound enhances bone repair in a rabbit model of steroid-associated osteonecrosis. Abstract Source: Clin Orthop Relat Res. 2015 May ;473(5):1830-9. Epub 2015 Mar 4. PMID: 25736917 Abstract Author(s): Hanxiao Zhu, Xunzi Cai, Tiao Lin, Zhongli Shi, Shigui Yan Article Affiliation: Hanxiao Zhu Abstract: BACKGROUND: Steroids are a leading cause of femoral head osteonecrosis. Currently there are no medications available to prevent and/or treat steroid-associated osteonecrosis. Low-intensity pulsed ultrasound (LIPUS) was approved by the FDA for treating delayed union of bone fractures. Some studies have reported that LIPUS can enhance bone formation and local blood flow in an animal model of fracture healing. However, whether the effect of osteogenesis and neovascularization by LIPUS can enhance the repair progress in steroid-associated osteonecrosis is unknown. QUESTIONS/PURPOSES: We hypothesized that LIPUS may facilitate osteogenesis and neovascularization in the reparative processes of steroid-associated osteonecrosis. Using a rabbit animal model, we asked whether LIPUS affects (1) bone strength and trabecular architecture; (2) blood vessel number and diameter; and (3) BMP-2 and VEGF expression. METHODS: Bilateral femoral head necrosis was induced by lipopolysaccharide and methylprednisolone in 24 rabbits. The left femoral heads of rabbits received LIPUS therapy (200 mW/cm(2)) for 20 minutes daily and were classified as the LIPUS group. The right femoral heads of the same rabbits did not receive therapy and were classified as the control group. All rabbits were euthanized 12 weeks after LIPUS therapy. Micro-CT, biomechanical testing, histologic evaluation, immunohistochemistry, quantitative real-time PCR, and Western blot were used for examination of the effects of LIPUS. RESULTS: Twelve weeks after LIPUS treatment, the loading strength in the control group was 355± 38 N (95% CI, 315-394 N), which was lower (p = 0.028) than that in the LIPUS group (441 ± 78 N; 95% CI, 359-524 N). The bone tissue volume density (bone volume/total volume) in the LIPUS group (49.29% ± 12.37%; 95 % CI, 36.31%-62.27%) was higher (p = 0.022) than that in the control group (37.93% ± 8.37%; 95 % CI, 29.15%-46.72%). The percentage of empty osteocyte lacunae in the LIPUS group (17% ± 4%; 95% CI, 15%-20%) was lower (p = 0.002) than that in the control group (26% ± 9%; 95% CI, 21%-32%). The mineral apposition rate (μm/day) in the LIPUS group (2.3 ± 0.8 μm/day; 95% CI, 1.82.8 μm/day) was higher (p = 0.001) than that in the control group (1.6 ± 0.3 μm/day; 95% CL, 1.4-1.8 μm/day). The number of blood vessels in the LIPUS group (7.8 ± 3.6/mm(2); 95% CI, 5.5-10.1 mm(2)) was greater (p = 0.025) than the number in the control group (5.7 ± 2.6/mm(2); 95% CI, 4.0-7.3mm(2)). Messenger RNA (mRNA) and protein expression of BMP-2 in the LIPUS group (75 ± 7, 95% CI, 70-79; and 30 ± 3, 95% CI, 28-31) were higher (both p<0.001) than those in the control groups (46± 5, 95% CI, 43-49; and 15 ± 2, 95% CI, 14-16). However, there were no differences (p = 0.114 and 0.124) in mRNA and protein expression of vascular endothelial growth factor between the control (26 ± 3, 95% CI, 24-28; and 22 ± 6, 95% CI, 18-26) and LIPUS groups (28 ± 2, 95% CI, 26-29; and 23 ±6, 95% CI, 19-27). CONCLUSIONS: The results of this study indicate that LIPUS promotes osteogenesis and neovascularization, thus promoting bone repair in this steroid-associated osteonecrosis model. CLINICAL RELEVANCE: LIPUS may be a promising modality for the treatment of early-stage steroid-associated osteonecrosis. Further research, including clinical trials to determine whether LIPUS has a therapeutic effect on patients with early-onset steroid-associated osteonecrosis may be warranted.

Abstract Title: Pain palliation in patients with bone metastases using magnetic resonance-guided focused ultrasound with conformal bone system: a preliminary report. Abstract Source: Yonsei Med J. 2015 Mar ;56(2):503-9. PMID: 25684002 Abstract Author(s): Bio Joo, Mi-Suk Park, Soo Hyeon Lee, Hye Jin Choi, Seung Tack Lim, Sun Young Rha, Itay Rachmilevitch, Young Han Lee, Jin-Suck Suh Article Affiliation: Bio Joo Abstract: PURPOSE: We evaluated the safety and effectiveness of the Magnetic Resonance-guided Focused Ultrasound (MRgFUS) with the ExAblate Conformal Bone System for the palliation of painful bone metastases. MATERIALS AND METHODS: Our Institutional Review Board approved this study, and all patients gave informed consent prior to enrollment. A total of six painful metastatic bone lesions in five patients were treated using MRgFUS with the ExAblate Conformal Bone System for pain palliation. The follow-up sessions were at 3 days, 2 weeks, 1, 2, and 3 months, and 1 year after treatment. Efficacy was evaluated by the changes in visual analog scale (VAS) scores. At 3-months and 1-year follow-ups, unenhanced computed tomography and contrast-enhanced MR imaging examinations were performed. All adverse events were assessed to evaluate treatment safety. RESULTS: All patients showed significant pain relief within 2 weeks. Two patients experienced complete pain reduction that lasted for 1 year. Two other patients showed pain relief measured as VAS scores of 2 and 4 on their last follow-up. Although the remaining patient had experienced significant pain relief in two lesions, the VAS score re-increased on his last follow-up. The size of the enhancing soft tissue mass in metastatic lesions decreased, and new bone formation was seen on follow-up images. Although adverse events were not serious, non-specific leg pain and second degree skin burn were noted. CONCLUSION: MRgFUS was demonstrated to be effective palliative treatment within 2 weeks in selected patients with painful bone metastases. Article Published Date : Feb 28, 2015

Abstract Title: Characterization of Dynamic Behaviour of MCF7 and MCF10A Cells in Ultrasonic Field Using Modal and Harmonic Analyses. Abstract Source: PLoS One. 2015;10(8):e0134999. Epub 2015 Aug 4. PMID: 26241649 Abstract Author(s): Annette Geltmeier, Beate Rinner, Dennis Bade, Katharina Meditz, Reiner Witt, Uwe Bicker, Catrin Bludszuweit-Philipp, Patrick Maier Article Affiliation: Annette Geltmeier Abstract: Treatment options specifically targeting tumour cells are urgently needed in order to reduce the side effects accompanied by chemo- or radiotherapy. Differences in subcellular structure between tumour and normal cells determine their specific elasticity. These structural differences can be utilised by low-frequency ultrasound in order to specifically induce cytotoxicity of tumour cells. For further evaluation, we combined in silico FEM (finite element method) analyses and in vitro assays to bolster the significance of low-frequency ultrasound for tumour treatment. FEM simulations were able to calculate the first resonance frequency of MCF7 breast tumour cells at 21 kHz in contrast to 34 kHz for the MCF10A normal breast cells, which was due to the higher elasticity and larger size of MCF7 cells. For experimental validation of the in silico-determined resonance frequencies, equipment for ultrasonic irradiation with distinct frequencies was constructed. Differences for both cell lines in their response to low-frequent ultrasonic treatment were corroborated in 2D and in 3D cell culture assays. Treatment with ~ 24.5 kHz induced the death of MCF7 cells and MDA-MB-231 metastases cells possessing a similar elasticity; frequencies of>29 kHz resulted in cytotoxicity of MCF10A. Fractionated treatments by ultrasonic irradiation of suspension myeloid HL60 cells resulted in a significant decrease of viable cells, mostly significant after threefold irradiation in intervals of 3 h. Most importantly in regard to a clinical application, combined ultrasonic treatment and chemotherapy with paclitaxel showed a significantly increased killing of MCF7 cells compared to both monotherapies. In summary, we were able to determine for the first time for different tumour cell lines a specific frequency of low-intensity ultrasound for induction of cell ablation. The cytotoxic effect of ultrasonic irradiation could be increased by either fractionated treatment or in combination with chemotherapy. Thus, our results will open new perspectives in tumour treatment. Article Published Date : Dec 31, 2014

Abstract Title: Ultrasound treatment for accelerating fracture healing of the distal radius. A control study. Abstract Source: Acta Cir Bras. 2014 Nov ;29(11):765-70. PMID: 25424299 Abstract Author(s): Yinwen Liu, Xiaoen Wei, Yong Kuang, Yuxin Zheng, Xinfeng Gu, Hongsheng Zhan, Yinyu Shi Article Affiliation: Yinwen Liu Abstract: PURPOSE: To investigate the accelerating effects of low-intensity pulse ultrasound stimulation (LIPUS) on the fracture healing of distal radius. METHODS: A total of 81 patients with distal radius fracture were randomly divided into two groups: the ultrasound treatment group and the control group. Patients in the ultrasound treatment group were immobilized in a below-elbow cast and received LIPUS treatment 15 min/day, while the control group were immobilized by a plaster support and cast. The patients were followed up every week and took X-ray films. The initial and healed X-ray films and the gray value of fracture site were analyzed by Photoshop software. The effect of reposition was evaluated based upon Steward recommended by Dienst, combining with Aro's measuring method. RESULTS: Clinical fracture healing time in ultrasound group was significantly shorter than that in the control group (32.04± 2.58d vs. 40.75 ± 5.12d, p<0.01). In addition, the grey value changes of fracture sites of the ultrasound group were much higher than that of the control group. The reposition effects of fracture healing had no difference between the two groups (p>0.05). CONCLUSION: Low-intensity pulse ultrasound stimulation could accelerate fracture healing of the distal radius and promote local bone formation. Article Published Date : Oct 31, 2014

Abstract Title: Salvage high-intensity focused ultrasound for patients with recurrent prostate cancer after brachytherapy. Abstract Source: Urology. 2014 Nov ;84(5):1157-62. Epub 2014 Oct 24. PMID: 25443920 Abstract Author(s): Vladimir Yutkin, Hashim U Ahmed, Ian Donaldson, Neil McCartan, Khurram Siddiqui, Mark Emberton, Joseph L Chin Article Affiliation: Vladimir Yutkin Abstract: OBJECTIVE: To report our experience with salvage high-intensity focused ultrasound (HIFU) in patients with local failure after brachytherapy for prostate cancer. PATIENTS AND METHODS: Whole-gland HIFU was administered to prospectively recruited patients with local histologic failure after brachytherapy at 2 institutions in the United Kingdom and Canada. Functional and oncologic outcomes of the procedure were analyzed. RESULTS: Nineteen patients underwent the treatment, 12 with Gleason sum 7 and 5 with Gleason sum 8 at recurrence. Thirteen men had grade-3a or -3b complications by the Clavien system; there were no grade-4 or -5 complications. The most common postoperative complication was dysuria, which was self-limited. Three men developed rectourethral fistulae. The overall continence rate was 68.4%. At a mean follow-up of 51.6 months, all men were alive. The overall biochemical recurrence-free survival rate was 66.7% and 73.3% using the"nadir prostate-specific antigen level"+1.3 ng/mL and +2 mg/ml criteria, respectively. This study is limited by the small cohort size, relatively short follow-up period, and heterogeneity of the patient population. CONCLUSION: In this, the largest prospective series to date, we demonstrate that salvage HIFU for locally recurrent prostate cancer after failed primary brachytherapy has encouraging disease control results, albeit with a relatively high complication rate.

Abstract Title: Comparison of high-frequency and MIST ultrasound therapy for the healing of venous leg ulcers. Abstract Source: Adv Clin Exp Med. 2014 Nov-Dec;23(6):969-75. PMID: 25618125 Abstract Author(s): Akram Beheshti, Younes Shafigh, Hossien Parsa, Amir A Zangivand Article Affiliation: Akram Beheshti Abstract: BACKGROUND: Venous leg ulcers (VLUs) are a health problem in clinical care. Several options can be employed as adjuvant to standard treatment. OBJECTIVES: We have aimed to analyze the effect of standard ulcer care alone with high-frequency ultrasound (HFU) and MIST ultrasound therapy on VLUs. MATERIAL AND METHODS: Ninety patients with VLUs were assigned into the standard treatment, HFU and MIST ultrasound groups. All groups received the standard wound care. In the ultrasound groups, HFU and MIST ultrasound therapy was administered to wounds 3 times per week until the wound healed. Time of complete wound healing was recorded. Wound size, pain, and edema were assessed at baseline and after 2 and 4 months. Also, patients were instructed to contact our clinic monthly, and recurrence of VLUs was recorded for 6 months after complete wound healing. The data was analyzed using a Student's t-test, ANOVA, c2, or Fisher's exact test. P<0.05 was considered significant. RESULTS: Mean time duration of complete wound healing in the first, second and third groups was 8.13 (SD 1.40), 6.10 (SD 1.47) and 5.70 (SD 1.57) months, respectively (p<0.0001). Size of ulcer, mean degree of pain and edema in ultrasound therapy was decreased after the 4-month visit in comparison to the standard-treatment group (p=0.01, p<0.0001 and p<0.0001, respectively). Also, our results don't show any significant differences between groups in the recurrence of VLUs during a 6-month follow up after complete wound healing (p=0.37). CONCLUSIONS: Our results in the present study show the significant effectiveness of ultrasound therapy in wound healing. Differences between the two ultrasound therapy groups were not statistically significant. Article Published Date : Oct 31, 2014

PMID: 24769010 Abstract Author(s): Juhua Xiao, Shouhua Zhang, Fang Wang, Yuqin Wang, Zhen Shi, Xin Zhou, Jinshui Zhou, Jinshi Huang Article Affiliation: Juhua Xiao Abstract: OBJECTIVE: The aim of this preliminary study was to investigate whether ultrasound-guided high-intensity focused ultrasound (HIFU) can play a role in treating cesarean scar pregnancy (CSP). STUDY DESIGN: Between November 2011 and December 2012, 16 patients with CSP were treated with ultrasound-guided HIFU ablation. Successful treatment was defined as disappearance of CSP mass, undetectable serum beta human chorionic gonadotropin, and no serious complications such as severe bleeding, uterine rupture, or hysterectomy. RESULTS: All patients were successfully treated in the outpatient department and none required readmission. After 2-5 treatment sessions, the mean time for achieving undetectable serum beta human chorionic gonadotropin was 4.94± 2.32 weeks, and the mean time for CSP mass disappearance was 6.69 ± 3.36 weeks. Three patients experienced moderate abdominal pain that subsided in 1-2 days, and nine patients experienced mild vaginal bleeding (<30 mL) that resolved within 2-3 days. All 16 patients had recovered their normal menstruation function at follow-up. CONCLUSION: These preliminary results suggest that ultrasound-guided HIFU ablation is a noninvasive, feasible, and effective method for the treatment of CSP. Article Published Date : Sep 30, 2014

The sample comprised 54 diagnosed subjects with a mean age of 36.54 y (standard deviation = 12.245), assigned by simple random selection to an experimental group with ultrasound treatment and a control group with placebo ultrasound. Treatment consisted of 10 sessions of an ultrasound treatment protocol, followed by 15 sessions of a protocol identical for both groups without ultrasound. The variables assessed were pain and joint mobility. There was no significant difference (p>0.05) between groups in the first 10 sessions of treatment. However, there was a statistically significant difference (p<0.05) between groups on the pain variable, 20 days after completion of the US. High-active ultrasound treatment is more effective than placebo in reducing pain. Article Published Date : Aug 31, 2014

Abstract Title: Case report: A breast cancer patient treated with GcMAF, sonodynamic therapy and hormone therapy. Abstract Source: Anticancer Res. 2014 Aug ;34(8):4589-93.

It has various functions, such as macrophage activation and antitumor activities. Recently, immunotherapy has become an attractive new strategy in the treatment of cancer. GcMAF-based immunotherapy can be combined with many other therapies. Sonodynamic therapy (SDT) using low-intensity ultrasound is a novel therapeutic modality. Ultrasound has been demonstrated to activate a number of sonosensitive agents allowing for the possibility of non-invasive targeted treatment for both superficial and deep-seated tumors. The current case study demonstrates that GcMAF and SDT can be used in combination with conventional therapies in patients with metastatic cancer, especially where treatment options are limited due to factors such as toxicity. This case study also suggests a new concept of cancer treatment using local destruction of cancer tissue, in this case conducted with SDT, to be used in combination with GcMAF immunotherapy as a systemic treatment.

PMID: 25071354 Abstract Author(s): Atsushi Sofuni, Fuminori Moriyasu, Takatomo Sano, Fumihide Itokawa, Takayoshi Tsuchiya, Toshio Kurihara, Kentaro Ishii, Syujiro Tsuji, Nobuhito Ikeuchi, Reina Tanaka, Junko Umeda, Ryosuke Tonozuka, Mitsuyoshi Honjo, Shuntaro Mukai, Mitsuru Fujita, Takao Itoi Article Affiliation: Atsushi Sofuni Abstract: AIM: To evaluate the safety and clinical application of high-intensity focused ultrasound (HIFU) therapy for unresectable pancreatic cancer (PC). METHODS: Thirty PC patients (16 cases in stage III and 14 cases in stage IV) with visualized pancreatic tumors were admitted for HIFU therapy as an optional local therapy in addition to systemic chemotherapy or chemoradiotherapy. Informed consent was obtained. This study began at the end of 2008 and was approved by the ethics committee of our hospital [Institutional Review Board (IRB): 890]. The HIFU device used was the FEP-BY02 (Yuande Bio-Medical Engineering, Beijing, China). RESULTS: The mean tumor size after HIFU therapy changed to 30.9± 1.7 mm from 31.7 ± 1.7 mm at pre-therapy. There were no significant changes in tumor size, mean number of treatment sessions (2.7 ± 0.1 mm), or mean total treatment time (2.4 ± 0.1 h). The rate of symptom relief effect was 66.7%. The effectiveness of primary lesion treatment was as follows: complete response, 0; partial response, 4; stable disease, 22; progressive disease, 4. Treatment after HIFU therapy included 2 operations, 24 chemotherapy treatments, and 4 best supportive care treatments. Adverse events occurred in 10% of cases, namely pseudocyst formation in 2 cases and mild pancreatitis development in 1. However, no severe adverse events occurred in this study. CONCLUSION: We suggest that HIFU therapy is safe and has the potential to be a new method of combination therapy for PC. Article Published Date : Jul 27, 2014

Abstract Title: Contribution of ultrasound in the assessment of patients with suspect idiopathic pudendal nerve disease. Abstract Source: Clin Neurophysiol. 2014 Jun ;125(6):1278-84. Epub 2013 Dec 7. PMID: 24368033 Abstract Author(s): Alberto Tagliafico, Bianca Bignotti, Maribel Miguel Perez, Lizia Reni, Gerd Bodner, Carlo Martinoli Article Affiliation: Alberto Tagliafico Abstract: OBJECTIVE: To assess if Ultrasound (US) is contributive in patients suspected of having idiopathic pudendal neuralgia. METHODS: Between July 2012 and April 2013, 10 consecutive female patients with suspected idiopathic pudendal neuralgia (mean age: 47±14 years; mean BMI: 24±3) were included. Two radiologists blinded to the clinical and neurophysiological data performed pudendal nerve evaluation with broadband linear array transducers (12-7 MHZ, and 17-5 MHZ). MRI was added to confirm US data. A third independent clinician, who did not performelectrodiagnosis and US, reviewed the data and scored US as"contributive"or"non-contributive": if US confirmed the clinical and neurophysiological diagnosis or if US findings were not useful. RESULTS: Ultrasound identified alterations to the pudendal nerve in 7/10 of cases (70%). In seven cases US revealed the presence of a diffusely or focally enlarged pudendal nerve confirmed by MRI. In these cases neurophysiological findings were suspicious for pudendal neuralgia in 5/7 cases, whereas in 2/7 cases they were inconclusive. CONCLUSION: High-resolution ultrasound (US) may demonstrate alterations to the pudendal nerve in patients with pudendal neuralgia. SIGNIFICANCE: US is useful in patients with suspected idiopathic pudendal nerve disease. Article Published Date : May 31, 2014

Abstract Title: MR-guided focused ultrasound (MRgFUS) ablation for the treatment of nonspinal osteoid osteoma: a prospective multicenter evaluation. Abstract Source: J Bone Joint Surg Am. 2014 May 7 ;96(9):743-51. PMID: 24806011 Abstract Author(s): D Geiger, A Napoli, A Conchiglia, L M Gregori, F Arrigoni, A Bazzocchi, M Busacca, O Moreschini, M Mastantuono, U Albisinni, C Masciocchi, C Catalano Article Affiliation: D Geiger Abstract: BACKGROUND: Magnetic resonance-guided focused ultrasound (MRgFUS) is a novel imaging-guided surgical technique that allows the performance of noninvasive and radiation-free ablation. Presently, computed tomography (CT)-guided radiofrequency ablation, a minimally invasive percutaneous technique, is the standard for treating symptomatic osteoid osteomas. The purpose of this study was to evaluate the use of MRgFUS ablation for the treatment of nonspinal osteoid osteomas in terms of technical success, complications, and clinical success through one year of follow-up. METHODS: In this prospective multicenter study, thirty consecutive patients with a nonspinal osteoid osteoma were enrolled between May 2010 and April 2012 at three different university centers; twenty-nine of the patients were treated with use of MRgFUS. Lesions had been previously diagnosed on the basis of imaging, including dynamic contrast-enhanced MR. The mean number of sonications and energy deposition were determined. Technical success was evaluated through an assessment of complications immediately after treatment. Clinical success was determined on the basis of pain reduction as measured with a visual analog scale (VAS), recurrence, and long-term complications through twelve months. RESULTS: Technical success of MRgFUS was observed for all twenty-nine patients. The mean number of sonications (and standard deviation) was 7± 3, and the mean delivered acoustic energy was 1180 ± 736 J. At the twelve-month follow-up, complete clinical success was observed in twenty-six (90%) of the twenty-nine patients (95% confidence interval [CI] = 84 to 95; mean VAS, 0 ± 0 points). Partial success was observed in three (10%) of thetwenty-nine patients (95% CI = 5 to 16; mean VAS score, 5 ± 0 points); two of these patients subsequently underwent CT-guided radiofrequency ablation, and one underwent open surgery. Pain score values showed a significant reduction (p<0.001) between baseline (mean VAS score, 8± 1 points) and post treatment (mean VAS score, 1 ± 2 points). No complications were observed. CONCLUSIONS: MRgFUS may be an effective and safe alternative approach in the treatment of nonspinal osteoid osteoma. A complete clinical success rate of 90% was demonstrated without adverse events. MRgFUS is totally noninvasive and eliminates radiation exposure. Article Published Date : May 06, 2014

Abstract Title: Magnetic resonance-guided focused ultrasound for patients with painful bone metastases: phase III trial results. Abstract Source: J Natl Cancer Inst. 2014 May ;106(5). Epub 2014 Apr 23. PMID: 24760791 Abstract Author(s): Mark D Hurwitz, Pejman Ghanouni, Sergey V Kanaev, Dmitri Iozeffi, David Gianfelice, Fiona Mary Fennessy, Abraham Kuten, Joshua E Meyer, Suzanne D LeBlang, Ann Roberts, Junsung Choi, James M Larner, Alessandro Napoli, Vladimir G Turkevich, Yael Inbar, Clare Mary C Tempany, Raphael M Pfeffer Article Affiliation: Mark D Hurwitz Abstract: BACKGROUND: Pain due to bone metastases is a common cause of cancer-related morbidity, with few options available for patients refractory to medical therapies and who do not respond to radiation therapy. This study assessed the safety and efficacy of magnetic resonance-guided focused ultrasound surgery (MRgFUS), a noninvasive method of thermal tissue ablation for palliation of pain due to bone metastases. METHODS: Patients with painful bone metastases were randomly assigned 3:1 to receive MRgFUS sonication or placebo. The primary endpoint was improvement in self-reported pain score without increase of pain medication 3 months after treatment and was analyzed by Fisher's exact test. Components of the response composite, Numerical Rating Scale for pain (NRS) and morphine equivalent daily dose intake, were analyzed by t test and Wilcoxon rank-sum test, respectively. Brief Pain Inventory (BPI-QoL), a measure of functional interference of pain on quality of life, was compared between MRgFUS and placebo by t test. Statistical tests were two-sided. RESULTS: One hundred forty-seven subjects were enrolled, with 112 and 35 randomly assigned to MRgFUS and placebo treatments, respectively. Response rate for the primary endpoint was 64.3% in the MRgFUS arm and 20.0% in the placebo arm (P<.001). MRgFUS was also superior to placebo at 3 months on the secondary endpoints assessing worst score NRS (P<.001) and the BPI-QoL (P<.001). The most common treatment-related adverse event (AE) was sonication pain, which occurred in 32.1% of MRgFUS patients. Two patients had pathological fractures, one patient had third-degree skin burn, and one patient suffered from neuropathy. Overall 60.3% of all AEs resolved on the treatment day. CONCLUSIONS: This multicenter phase III trial demonstrated that MRgFUS is a safe and effective, noninvasive treatment for alleviating pain resulting from bone metastases in patients that have failed standard treatments.

Abstract: An estimated 15% of patients with diabetes will develop a foot ulcer sometime in their life, making them 30 to 40 times more likely to undergo amputation due to a non-healing foot ulcer than the non-diabetic population. To determine the safety and efficacy of a new, non-contact, kilohertz ultrasound therapy for the healing of recalcitrant diabetic foot ulcers - as well as to evaluate the impact on total closure and quantitative bacterial cultures and the effect on healing of various levels of sharp/surgical debridement - a randomized, double-blinded, sham-controlled, multicenter study was conducted in hospital-based and private wound care clinics. Patients (55 met criteria for efficacy analysis) received standard of care, which included products that provide a moist environment, offloading diabetic shoes and socks, debridement, wound evaluation, and measurement. The "therapy" was either active 40 KHz ultrasound delivered by a saline mist or a "sham device" which delivered a saline mist without the use of ultrasound. After 12 weeks of care, the proportion of wounds healed (defined as complete epithelialization without drainage) in the active ultrasound therapy device group was significantly higher than that in the sham control group (40.7% versus 14.3%, P = 0.0366, Fisher's exact test). The ultrasound treatment was easy to use and no difference in the number and type of adverse events between the two treatment groups was noted. Of interest, wounds were debrided at baseline followed by a quantitative culture biopsy. The results of these cultures demonstrated a significant bioburden (greater than 10(5)) in the majority of cases, despite a lack of clinical signs of infection. Compared to control, this therapeutic modality was found to increase the healing rate of recalcitrant, diabetic foot ulcers. Article Published Date : Aug 01, 2005
