RESUMO

RATIONALE: Osteochondritis dissecans (OCD) lesions involve disruption of the osteochondral unit along articular surfaces, with significant potential for joint deterioration if not managed appropriately. PATIENT CONCERNS: A 15-year-old male presented with persistent and insidious right knee pain, which had worsened following a collision with another player during a basketball game, resulting in episodes of locking. DIAGNOSES: Magnetic resonance imaging revealed a lateral trochlear OCD extending into the anterior lateral femoral condyle. INTERVENTIONS: Chondral fraying was observed along the margins of the OCD. Retrograde drilling ensued with use of a 0.045-inch Kirschner wire throughout the lesion to a depth that would allow for penetration of healthy underlying subchondral bone to create an influx of healing factors. Three resorbable pegs were arthroscopically placed through an accessory portal overlying the lesion to stabilize the fracture and compress the gapped cartilage mantle to reduce flow of synovial fluid behind the lesion. Bipolar radiofrequency coblation was used to stabilize the chondral fraying and seal the gap along the periphery of the lesion. OUTCOMES: The patient was put on a nonweight bearing protocol for 6 weeks, after which crutches and brace were discontinued, but therapy persisted. Repeat imaging at 3 months demonstrated excellent interval healing. The patient was released to slowly engage impact activities. Although he returned at approximately 8 months postoperatively with a contralateral anterior cruciate ligament tear, he reported the operative knee with the OCD was doing extremely well. LESSONS: Radiofrequency coblation appears to be a viable strategy as an adjunct to management for OCD in children.

RESUMO

BACKGROUND: Knee osteoarthritis (KOA) is characterized by the clinical symptoms of chronic knee pain and knee dysfunction, leading to disability and influencing the quality of life in severe cases. Radiofrequency treatment is a new method to reduce KOA-related pain and partially improve knee joint dysfunction without adverse effect. OBJECTIVE: The present study aimed to assess the treatment efficacy of radiofrequency thermocoagulation on the genicular nerve (RFTGN) and intraarticular pulsed radiofrequency (IAPRF) for KOA. STUDY DESIGN: Retrospective comparative study design. SETTING: This study took place at Shengjing Hospital of China Medical University. METHOD: KOA patients were randomly assigned to the RFTGN, IAPRF, and intraarticular steroid injection (IAS) groups. All procedures were performed under the guidance of computed tomography (CT). The observation indicators of this study were the numeric rating scale (NRS), Oxford knee scale (OKS), and perceived global effect (GPE). The time points for the assessment were 1-week, 1-month, 3-months, and 6-months after the treatment. RESULTS: The postoperative NRS scores in the 3 groups decreased significantly at all the observation time points as compared to the pretreatment scores (P < 0.05). For the patients in the IAS group, the analgesic effect was in a rebound trend, which was the best at 1-week posttreatment, and was close to the preoperative level at 6-months posttreatment. The short-term (1 week or 1 month) analgesic effect of the RFTGN group was better than that of the IAPRF group, and was similar in the long-term (3 or 6 months). The long-term analgesic effect of RFTGN and IAPRF groups was better than that of IAS group. The results of the OKS score were similar to the NRS score. The RFTGN group showed markedly improved knee function in the long-term than the IAPRF and IAS groups. The short-term treatment satisfaction was similar in each group, and some differences were detected between the groups with respect to long-term treatment satisfaction. LIMITATION: This study was a single-center retrospective study with a relatively small sample cohort and short follow-up periodCONCLUSION: Both RFTGN and IAPRF could alleviate the knee joint pain and improve the knee joint dysfunction; however, the treatment efficacy of RFTGN was better than that of IAPRF.

RESUMO

OBJETIVO: Demostrar si un protocolo de rehabilitación multimodal (biofeedback [BFB] más radiofrecuencia [RF] capacitiva-resistiva [INDIBA®]) disminuye el dolor y aumenta la fuerza muscular en los pacientes con dolor pélvico crónico (DPC) y dispareunia. MATERIAL Y MÉTODOS: Estudio prospectivo cuasiexperimental tipo antes-después a 37 pacientes con DPC y/o dispareunia derivados al Servicio de Rehabilitación del Hospital Universitario Santa Cristina (enero-2016 a diciembre-2018). El protocolo consistió en 8 sesiones de ejercicios de musculatura del suelo pélvico asistido con BFB manométrico (ejercicios tónicos/fásicos 15min, respectivamente) supervisado por fisioterapeuta, seguido de RF bipolar capacitiva (5min)/resistiva (10min) a nivel suprapúbico y perineovaginal. Las variables evaluadas fueron el dolor (EVA 0-10) y la fuerza (mmHg) de la musculatura del suelo pélvico al inicio/término del tratamiento. RESULTADOS: Edad media, 41,5±12,65 años. Es más frecuente entre los 21-40 años (n=20, 54%) y los 41-60 años (n=12; 32.4%). Dispareunia, n=34 (91,8%); DPC inespecífico, n=3 (8,2%). El protocolo mejoró el dolor (de 7,27±1,34 a 3,75±2,21 puntos), la fuerza muscular máxima (de 25,56±15,9mmHg a 35,35±20,4mmHg) y la media (de 4,86±3,53mmHg a 7,18±4,46mmHg), respectivamente (p < 0,0001). CONCLUSIÓN: EL DPC y la dispareunia suponen un reto diagnóstico que requiere un manejo multidisciplinario. El tratamiento debe iniciarse precozmente y con la asociación de diferentes modalidades terapéuticas. El protocolo de rehabilitación multimodal que incluye al BFB y a la RF capacitiva-resistiva disminuye el dolor y mejora la fuerza en los pacientes con DPC y dispareunia


OBJECTIVE: To determine whether a multimodal rehabilitation protocol (Biofeedback [BFB] plus capacitive-resistive [INDIBA®] radiofrequency [RF]) reduces pain and increases muscular strength in patients with chronic pelvic pain (CPP) and dyspareunia. MATERIAL AND METHODS: We performed a prospective, quasi-experimental, before-after study in 37 patients with CPP and/or dyspareunia referred to the Rehabilitation Department of Hospital Universitario Santa Cristina (January 2016 to December 2018). The protocol consisted of 8 sessions of pelvic floor exercises assisted by manometric BFB (15min of tonic/phasic exercises each) supervised by a physiotherapist, followed by suprapubic and perineovaginal bipolar RF [capacitive(5 min)/resistive(10 min)]. The variables evaluated were pain (VAS 0-10) and strength (mmHg) of the pelvic floor musculature and the start/end of the treatment. RESULTS: The mean age was 41.5±12.65 years. The prevalence was higher among women aged 21-40 years (n=20, 54%) and those aged 41-60 years (n=12; 32.4%). Dyspareunia was present in 34 patients (91.8%), and non-specific CPP in 3 (8.2%). The protocol improved pain (from 7.27±1.34 to 3.75±2.21 points), maximal muscular strength (from 25.56±15.9mmHg to 35.35±20.4mmHg) and mean muscular strength (from 4.86±3.53mmHg to 7.18±4.46mmHg) respectively (p < 0.0001). CONCLUSION: CPP and dyspareunia are a diagnostic challenge that requires multidisciplinary management. Treatment should be started early and should consist of distinct therapeutic modalities. The protocol of multimodal rehabilitation including BFB and capacitive-resistive RF reduces pain and improves strength in patients with CPP and dyspareunia

RESUMO

Management of musculoskeletal (MSK) tumours has traditionally been delivered by surgeons and medical oncologists. However, in recent years, image-guided interventional oncology (IO) has significantly impacted the clinical management of MSK tumours. With the rapid evolution of relevant technologies and the expanding range of clinical indications, it is likely that the impact of IO will significantly grow and further evolve in the near future.In this narrative review, we describe well-established and new interventional technologies that are currently integrating into the IO armamentarium available to radiologists to treat MSK tumours and illustrate new emerging IO indications for treatment.

RESUMO

BACKGROUND: Oesophageal radiofrequency reduces use of proton pump inhibitors (PPIs) in patients with gastro-oesophageal reflux disease responding to PPIs. AIM: To determine the efficacy of oesophageal radiofrequency in patients with PPI-refractory heartburn. METHODS: A randomised, double-blind, sham-controlled multicentre study was designed to assess the efficacy of oesophageal radiofrequency in PPI non-responding patients with heartburn. Patients had moderate-to-severe heartburn defined by at least 3 occurrences a week, and not improved by continuous PPI treatment. The primary endpoint was clinical success at week 24, defined by intake of less than 7 PPI doses over the 2 preceding weeks and adequate symptom control determined by the patient. RESULTS: Sixty two patients were randomised, 29 to the oesophageal radiofrequency group and 33 to the sham group. Intention-to-treat analysis showed that 1/29 (3.4%) and 5/33 (15.1%) achieved the primary endpoint in the oesophageal radiofrequency and sham groups, respectively (NS). There was no significant difference between oesophageal radiofrequency and sham regarding the number of days without heartburn, days with PPI consumption in the last 2 weeks, and patients not taking PPIs. No pH-impedance parameter was associated with clinical response. The occurrence of adverse events was similar in both groups. CONCLUSION: This sham-controlled, randomised study did not demonstrate any efficacy of oesophageal radiofrequency for the treatment of PPI-refractory heartburn regarding symptom relief or consumption of PPIs.

RESUMO

Temporomandibular disorders (TMD) is one of the most common problem in contemporary dentistry. It is a term covering dysfunction of the masticatory muscles and the temporomandibular joints. Patients are suffering from severe pain, followed by limited mandibular opening and sounds in the temporomandibular joints during jaw movement. TMD influences the quality of life because the symptoms can become chronic and difficult to manage. Radiofrequency waves (RF) are electromagnetic waves with low energy and high frequency. They provide pain relief without causing significant damage to the nervous tissue. The RF therapy is commonly used for physiotherapeutic treatment of skeletal muscle relaxation, as a supportive therapy. The rehabilitation effect of these waves is based on diathermy by means of high-voltage quick alternating current. RF has also found application in physical therapy, as a therapeutic tool for various types of chronic pain syndromes. The aim of this literature review is to show the beneficial effect of radiofrequency waves on the pain of the masticatory muscles in the course of TMD.

RESUMO

OBJECTIVES: To evaluate the cost-effectiveness of radiofrequency denervation when added to a standardized exercise program for patients with chronic low back pain. METHODS: An economic evaluation was conducted alongside 3 pragmatic multicenter, nonblinded randomized clinical trials (RCTs) in The Netherlands with a follow up of 52 weeks. Eligible participants were included between January 1, 2013, and October 24, 2014, and had chronic low back pain; a positive diagnostic block at the facet joints (n = 251), sacroiliac (SI) joints (n = 228), or a combination of facet joints, SI joints, and intervertebral discs (n = 202); and were unresponsive to initial conservative care. Quality-adjusted life-years (QALYs) and societal costs were measured using self-reported questionnaires. Missing data were imputed using multiple imputation. Bootstrapping was used to estimate statistical uncertainty. RESULTS: After 52 weeks, no difference in costs between groups was found in the facet joint or combination RCT. The total costs were significantly higher for the intervention group in the SI joint RCT. The maximum probability of radiofrequency denervation being cost-effective when added to a standardized exercise program ranged from 0.10 in the facet joint RCT to 0.17 in the SI joint RCT irrespective of the ceiling ratio, and 0.65 at a ceiling ratio of €30 000 per QALY in the combination RCT. CONCLUSIONS: Although equivocal among patients with symptoms in a combination of the facet joints, SI joints, and intervertebral discs, evidence suggests that radiofrequency denervation combined with a standardized exercise program cannot be considered cost-effective from a societal perspective for patients with chronic low back pain originating from either facet or SI joints in a Dutch healthcare setting.

RESUMO

In recent years, the number of patients applying for prosthetic treatment due to temporomandibular joint disorders (TMD) has been increasing. The main methods for treating disorders are the use of occlusal splints and physiotherapeutic rehabilitation as supportive treatment. Radio waves are electromagnetic waves with radiation frequency between 3 Hz and 3 THz, used for physiotherapeutic treatment of skeletal muscle relaxation in the range of 3 to 6 MHz. The rehabilitation effect of these waves is based on diathermy by means of high-voltage quick alternating current. Aim. The aim of the study was to evaluate the influence of radiofrequency waves on the pain of the masticatory muscles in the course of TMD and the usefulness of these procedures in the supporting treatment of these disorders. Materials and Methods. Patients aged 19 to 45 years, of both sexes, reported to the Consulting Room of TMD at the Institute of Dentistry in Krakow to undertake prosthetic treatment of TMD (I a-according to RDC/TMD). Study group (SG) consists of 20 patients who had 10 supportive treatments with radiofrequency currents. In the case of application of radiation to the muscle area, the energy was 20 J to the area of the masticatory muscles, the frequency was 3 MHz, bipolar technique, the duration of the procedure was 10 minutes, and the coupling substance was a gel for ultrasound examinations. The control group (CG) consisted of 20 patients who had 10 supportive treatments with sonophoresis procedures. For the area of masticatory muscles, 0.9 W/cm2 treatments were applied, the duty factor was 80%, the treatment time was 10 minutes, and the medical substance was 25% Voltaren gel. Results. Analysis of the results of the first clinical examinations (axis I) conducted in both groups shows a homogeneous clinical material and similar results. The second clinical examination revealed improved clinical parameters, but it showed a greater improvement in the SG. In the SG, the mean level of VAS was 6.25, and the extreme values were 5.9-0.14, the median was 2.15, and the standard deviation was 1.54. In the CG, the average value of VAS was 6.20 (peak of 5.2-0.7), the median was 2.4, and the standard deviation was 1.87. Summary. The search for new methods of supportive treatment of TMD is an important research direction due to the complex etiology of this disease and the lack of an explicit treatment algorithm. Conclusion. The results of our own research clearly indicate that the use of the radiofrequency waves brings pain relief and improvement of clinical parameters to a greater extent than in sonophoresis. It can be a very important new method in supportive treatment of TMD. Research needs to be continued.

RESUMO

OBJECTIVE: To evaluate the reduction of perineal pain after vaginal deliveries by capacitive resistive radiofrequency therapy (RF). METHODS: We conducted a double-blind randomized study in University Hospital Centre in France. We included women presenting either perineal tears or an episiotomy after vaginal delivery (instrumental assisted or not). The participants were randomly assigned to RF or not at day 1 and day 2 postpartum. The primary outcome was pain evaluated as visual analog scale (VAS) score >4 at rest on day 2 after the treatment. Secondary outcomes included discomfort and pain while walking and seating two days after treatment, type of pain two days after treatment and analgesics intake two days after treatment, sexual intercourse retake and painful of intercourse were also assessed by phone call 30 days after delivery. We performed univariate analysis and multivariable regressions adjusting on the value of the outcome at baseline to improve precision of the estimated intervention effect. RESULTS: Between June 1, 2017 and October 8, 2017, the RF group included 29 women compared with 31 women in the group without RF. There was no significant difference on VAS >4 between the two groups (13.8% vs. 9.7% p = 0.69; difference = 4.1%, 95%CI -12.2%- 20.4%); consumption of paracetamol was lower in the RF group (978.3 mg (sd = 804.5) vs 1703.7 mg (sd = 1381.6), p = 0.035; difference = -725.3 mg, 95%CI -1359.6 - -91.3). Multivariate analysis showed no association between RF and pain. Nevertheless, we found an association between RF and discomfort while walking (adjusted OR 0.24, 95% CI 0.07-0.90; p = 0.03). CONCLUSION: VAS>4 at day 2 was not different in the experimental and the control groups but RF was associated with less perineal discomfort while walking and lower consumption of paracetamol after delivery. CLINICAL TRIAL REGISTRATIONS: The study was registered in the Clinical Government trial (https://clinicaltrials.gov/ct2/show/NCT03172286?term=bretelle&rank=2) under the number NCT03172286.

RESUMO

Whilst surgical resection is traditionally used for the successful eradication of locally aggressive osseous tumors, it is often hazardous or unachievable, particularly in complex anatomic sites, such as the pelvis and spine. The authors present the use of microwave ablation in combination with Zoledronic acid (ZA) administration, alone and with the use of ZA-loaded polymethyl methacrylate (PMMA) to percutaneously treat unresectable bone tumors in 4 patients with giant cell tumors (GCT), multiple myeloma (MM) and breast cancer metastasis.

RESUMO

The purpose of this study was to evaluate the quality of surface contouring of chondromalacic cartilage by bipolar radio frequency energy using different treatment patterns in an animal model, as well as examining the impact of the treatment onto chondrocyte viability by two different methods. Our experiments were conducted on 36 fresh osteochondral sections from the tibia plateau of slaughtered 6-month-old pigs, where the thickness of the cartilage is similar to that of human wrist cartilage. An area of 1 cm2 was first treated with emery paper to simulate the chondromalacic cartilage. Then, the treatment with RFE followed in 6 different patterns. The osteochondral sections were assessed for cellular viability (live/dead assay, caspase (cell apoptosis marker) staining, and quantitative analysed images obtained by fluorescent microscopy). For a quantitative characterization of none or treated cartilage surfaces, various roughness parameters were measured using confocal laser scanning microscopy (Olympus LEXT OLS 4000 3D). To describe the roughness, the Root-Mean-Square parameter (Sq) was calculated. A smoothing effect of the cartilage surface was detectable upon each pattern of RFE treatment. The Sq for native cartilage was Sq = 3.8 ± 1.1 µm. The best smoothing pattern was seen for two RFE passes and a 2-second pulsed mode (B2p2) with an Sq = 27.3 ± 4.9 µm. However, with increased smoothing, an augmentation in chondrocyte death up to 95% was detected. Using bipolar RFE treatment in arthroscopy for small joints like the wrist or MCP joints should be used with caution. In the case of chondroplasty, there is a high chance to destroy the joint cartilage.

RESUMO

Background: Primary V1 trigeminal neuralgia is a common refractory neuralgia in clinical practice, lacking effective treatments. Radiofrequency therapy has certain treatment efficacy, but its long-term efficacy remained poor and the disease might relapse. Objective: To compare the effects of different types of supraorbital foramen variations on the treatment efficacy of radiofrequency therapy for V1 trigeminal neuralgia. Methods: Data of 54 patients with V1 trigeminal neuralgia who underwent treatment in the First Hospital of Jiaxing, Zhejiang, were retrospectively analyzed. All these patients received CT-guided radiofrequency thermocoagulation of supraorbital nerve. According to the CT images, the supraorbital foramen of the patients was categorized as holes (hole group) or notches (notch group). The patient characteristics, including Numerical Rating Scale (NRS) score and effective treatment rates before and 1 d, 0.5 y, 1 y, and 2 y after operation, and numbness degree at day 1 and 2 y after the operation were compared. The short- and long-term complications during postoperative follow-up period were also recorded. Results: Among the 54 patients, 25 patients were grouped into the hole group and 29 into the notch group. The NRS scores before and at 1 d, 0.5 y, 1 y, and 2 y after operation showed no significant differences between the two groups. However, the NRS scores at the remaining time points after operation were significantly decreased when compared with scores before operation (P < 0.05). The numbness and numbness degree after operation showed no significant differences between the two groups. The numbness degree at 2 y after operation was significantly lower than 1 d after operation (P < 0.05). The numbness and numbness degree after operation showed no significant differences between the two groups. The numbness degree at 2 y after operation was significantly lower than 1 d after operation (P < 0.05). The numbness and numbness degree after operation showed no significant differences between the two groups. The numbness degree at 2 y after operation was significantly lower than 1 d after operation (. Conclusion: The short- and long-term effective rates of radiofrequency therapy during V1 trigeminal neuralgia treatment are relatively high in patients with different types of supraorbital foramen variations. However, the effective rate is even higher in patients with hole-type supraorbital foramen. No other severe complications, except numbness, were found, and the acceptability rate remained high in patients.

RESUMO

Gastroesophageal reflux disease (GERD) is the most frequent outpatient diagnosis in the United States. There has been significant development in the endoscopic treatment of GERD, with several devices that have reached the market. One of the endoscopic devices for the management of GERD in the United States is the Stretta system. This procedure uses radiofrequency energy, which is applied to the muscles of the lower esophageal sphincter and the gastric cardia resulting in an improvement of reflux symptoms. This review evaluates the most recent data on the efficacy, mechanisms of action, and safety of this procedure.

RESUMO

BACKGROUND: New minimal invasive surgeries have been suggested as alternative options to transurethral resection of the prostate (TURP) for the management of lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). Convective radiofrequency water vapour thermal therapy is a new technology that uses targeted, controlled water vapour energy (steam) to create necrotic tissue in the prostate. OBJECTIVES: To assess the effects of convective radiofrequency water vapour thermal therapy for the treatment of lower urinary tract symptoms in men with benign prostatic hyperplasia. SEARCH METHODS: We performed a comprehensive search of multiple databases (the Cochrane Library, MEDLINE, Embase, Latin American and the Caribbean Health Sciences Literature, Scopus, Web of Science), trials registries, other sources of grey literature, and conference proceedings published up to 18 February 2020, with no restriction on the language or status of publication. SELECTION CRITERIA: We included parallel-group randomised controlled trials (RCTs), cluster-RCTs, and non-randomised observational prospective studies with concurrent comparison groups, in which men with BPH underwent convective radiofrequency water vapour thermal therapy, another active therapy, or a sham procedure. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the literature, extracted data, and assessed risk of bias. We had planned to perform statistical analyses using a random-effects model, and interpret them according to the Cochrane Handbook for Systematic Reviews of Interventions. We rated the certainty of the evidence according to the GRADE approach. MAIN RESULTS: We included a single, industry-sponsored RCT, with 197 randomised men, that compared convective radiofrequency water vapour thermal therapy to a sham procedure. The mean age 62.9 years, the International Prostate Symptom Score (IPSS) was 21.97, and the mean prostate volume was 45.4 mL. We only found short-term data, measured up to three months. Primary outcomes Convective radiofrequency water vapour thermal therapy may improve urologic symptom scores more than a sham procedure, measured on a IPSS scale (0 to 35; higher score represents worse urological symptoms) by a mean difference (MD) of -6.9 (95% confidence interval (CI) -9.06 to -4.74; 195 men; low-certainty evidence), and likely improves quality of life (QoL), measured on a IPSS-QoL scale (0 to 6; higher score represents worse QoL), by a MD of -1.2 (95% CI -1.66 to -0.74; 195 men; moderate-certainty evidence). We are very uncertain about the effects of convective radiofrequency water vapour thermal therapy on major adverse events (risk ratio (RR) 6.79, 95% CI 0.39 to 117.00; 197 men; very low-certainty evidence) assessed by the Clavien-Dindo classification system of III, IV, and V complications. Secondary outcomes We are very uncertain about the effects of convective radiofrequency water vapour thermal therapy on retreatment (RR 1.36, 95% CI 0.06 to 32.86; 197 men; very low-certainty evidence). Convective radiofrequency water vapour thermal therapy may have little to no effect on erectile function (MD 0.4, 95% CI -1.91 to 2.71; 130 men; low-certainty evidence) and ejaculatory function (MD 0.5, 95% CI -0.83 to 1.83; 130 men; low-certainty evidence). Convective radiofrequency water vapour thermal therapy may increase minor adverse events assessed by the Clavien-Dindo classification system of Grade I and II complications (RR 1.89, 95% CI 1.15 to 3.11; 197 men; low-certainty evidence). This would correspond to 434 minor adverse events per 1000 men (95% CI 264 more to 714 more). We are very uncertain about the effects of convective radiofrequency water vapour thermal therapy on acute urinary retention (RR 4.98, 95% CI 0.28 to 86.63; 197 men; very low-certainty evidence). It likely greatly increases the rate of men requiring indwelling urinary catheters (RR 35.58, 95% CI 15.37 to 82.36; 197 men; moderate-certainty evidence). We were unable to perform any of the predefined secondary analyses. We found no evidence for other comparisons, such as convective radiofrequency water vapour thermal therapy versus TURP or other minimal invasive procedures. AUTHORS' CONCLUSIONS: Compared to a sham procedure, urologic symptom scores and quality of life appear to improve with convective radiofrequency water vapour thermal therapy, but we are very uncertain about major adverse events. The certainty of evidence ranged from moderate to very low, with study limitations and imprecision being the most common reasons for rating down. These findings are based on a single industry-sponsored study, with three-month short-term follow-up. We did not find any studies comparing convective radiofrequency water vapour thermal therapy to any other active treatment form, such as TURP.

RESUMO

INTRODUCTION: Radiofrequency (RF)-based treatment has been introduced as an esthetic alternative treatment for various medical indications without the scientific backup of a satisfactory body of evidence. Furthermore, the United States Food and Drug Administration issued a warning regarding the safety of energy-based technologies for indications such as vaginal "rejuvenation," cosmetic vaginal treatment, vaginal conditions related to menopause, and symptoms of urinary incontinence and sexual function on July 30, 2018. AIM: To perform a thorough review of the existing literature regarding RF-based vaginal devices for the treatment of female genitourinary indications and summarize the evidence available in a few short statements. METHODS: A thorough review of the literature regarding RF treatments for gynecological indications was performed based on several databases. Studies that included at least 15 patients were eligible for analysis. MAIN OUTCOME MEASURE: Efficacy of RF devices for different genitourinary indications. RESULTS: Although a high level of heterogeneity of studies poses a serious challenge, the committee reached a decision on several statements related to the use of RF-based devices for genitourinary indications. CLINICAL IMPLICATIONS: RF-based vaginal treatments have not been studied thoroughly enough in order to establish decisive recommendations regarding their safety and efficacy. STRENGTH & LIMITATIONS: These position statements have been established by a group of experts. The lack of strong evidence makes it difficult to give decisive recommendations. CONCLUSIONS: Further randomized controlled trials with proper methodology and design are required to establish both benefits and possible harm these treatments may have in both short and long term for all the different indications studied.

RESUMO

PURPOSE OF REVIEW: Chronic ankle pain is a prevalent and significant cause of chronic pain. While the definition of chronic ankle pain is heterogeneous and poorly defined in the literature, systematic reviews and meta-analyses have estimated this condition to be a prevalent and debilitating source of chronic pain. The most identifiable and prominent cause of chronic ankle pain is chronic ankle instability (CAI), a condition defined by instability of the ankle-joint complex. It is a common consequence of lateral ankle sprains or ligamentous injuries and can be described as a failure of the lateral ankle joint complex after an acute, or recurring, ankle injury. The objective of this manuscript is to provide a comprehensive review of CAI diagnosis and our current understanding of minimally invasive treatment options. RECENT FINDINGS: First-line treatment is conservative management, some of which includes neuromuscular rehabilitation, balance training, nonsteroidal anti-inflammatory drugs (NSAIDs), manual mobilization, ice therapy, and compression. While conservative management is effective, additional treatments for those who fail conservative management, or who seek alternative options also have been explored. Recent advances and modern techniques have expanded available treatment options, many of which are becoming less invasive, and have shown improving functionality, recovery, and patient satisfaction. Minimally invasive treatments highlighted in this review include: arthroscopic surgery, steroid injections, plasma-rich plasma injections, hyaluronic acid (HA) injections, medicinal signaling cell injections, radiofrequency therapies, and shockwave therapies. This review will discuss some of these current treatments for minimally invasive treatment of CAI, as well as suggest novel treatments for clinical trials and further investigation.
