Extracorporeal shock wave treatment of capsular fibrosis after mammary augmentation – Preliminary results

Aesthetic Rehabilitation Medicine: Enhancing Wellbeing beyond Functional Recovery

Although rehabilitation medicine emphasizes a holistic health approach, there is still a large gap of knowledge about potential interventions aimed at improving overall wellbeing through cosmetic interventions. Therefore, this narrative review investigates the role of different rehabilitative techniques in enhancing aesthetics, quality of life, and psychosocial wellbeing for patients with disabilities. The study follows the SANRA framework quality criteria for a narrative review. Literature searches across PubMed/Medline, Web of Science, and Scopus identified articles focusing on rehabilitation strategies within the aesthetic rehabilitation domain. The review identified evidence supporting injection procedures, such as Botulinum Toxin, Platelet-Rich Plasma, Hyaluronic Acid, Ozone, and Carboxytherapy, and assessing their applications in several disabling disorders. Additionally, physical therapies like Extracorporeal Shock Wave Therapy, Laser Therapy, Microcurrent Therapy, Tecar Therapy, and physical exercises were explored for their impact on cutaneous microcirculation, cellulite treatment, wound healing, and scar appearance improvement. Lastly, the manuscript underlines the role of manual therapy techniques in addressing both physical discomfort and aesthetic concerns, discussing their effectiveness in adipose tissue therapy, scar tissue mobilization, and regional fat thickness reduction. Taken together, this review emphasizes the role of a multidisciplinary approach, aiming to provide valuable insights into potential benefits for both functional and aesthetic outcomes.

Focused electromagnetic high-energetic extracorporeal shockwave (ESWT) reduces pain levels in the nodular state of Dupuytren's disease-a randomized controlled trial (DupuyShock)

Dupuytren’s disease is a progressive fibroproliferative disorder of the hand. In the nodular stage of Dupuytren’s disease, pain might limit daily hand activities and progress to finger contractures. Focused electromagnetic high-energetic extracorporeal shockwave therapy (ESWT) may reduce pain in Dupuytren’s nodules (Tubiana N). In this prospective, randomized, blinded, placebo-controlled single center trial, we enrolled 52 patients (mean age, 58.2 ± 9.2) with painful nodular Dupuytren disease Tubiana N. Randomization was done to either (group A) 3 treatments with focused electromagnetic high-energetic ESWT (2000 shots, 3 Hz, 0.35 mmJ/mm²/hand, Storz Duolith SD1, n = 27) or (group B) placebo ESWT (2000 shots, 3 Hz, 0.01 mJ/mm²/hand, n = 25) in a weekly interval. Primary outcome was the level of pain on a visual analogue scale (VAS 0–10) at 3/6/12/18 months, secondary outcomes were patient-related outcome measures (DASH score, MHQ score, URAM scale), grip strength, patient’s satisfaction, and Dupuytren’s disease progression over 18 months follow-up. Focused ESWT significantly improved outcomes. Pain was reduced from 3.6 ± 1.8 to 1.9 ± 1.2 at three, to 1.4 ± 0.7 at six, to 1.7 ± 1.6 after 12 months and 1.9 ± 0.8 after 18 months in the intervention group (47% reduction, p < 0.05). In the placebo group, pain on VAS increased from 2.2 ± 1.4 to 3.4 ± 1.7 at three, to 3.4 ± 1.8 at six, to 3.4 ± 1.4 at 12 and 3.1 ± 1.1 at 18 months (35% increase, p < 0.05). Quality-of-life score tended to improve in the intervention group (MHQ, 77 ± 19 to 83 ± 12; DASH, 12 ± 18 to 10 ± 9) while it deteriorated in the placebo group as Dupuytren’s disease was progressing (MHQ, 79 ± 15 to 73 ± 17; DASH, 6 ± 10 to 14 ± 13). The strength of the affected hand and fingers did not change significantly in either of the groups. Patients’ satisfaction was higher in the intervention group for symptom improvement (56% vs. 12%) and reduction of disease progression (59% vs. 24%). Any Dupuytren-related intervention was performed in 26% in the intervention group and in 36% in the placebo group within 18 months of follow-up (n.s.). Focused electromagnetic high-energetic ESWT can significantly reduce pain in painful nodules in Dupuytren’s disease in an 18-month perspective. (ClinicalTrials.gov Identifier: NCT01184586).

Radial Extracorporeal Shock Wave Therapy as a Novel Agent for Benign Prostatic Hyperplasia Refractory to Current Medical Therapy

This study aimed to assess efficacy and safety data from pilot trials of the radial extracorporeal shock wave therapy (rESWT) to treat benign prostatic hyperplasia (BPH) refractory to current medical therapy. A total of 29 men with lower urinary tract symptoms (LUTS) suggestive of BPH who had responded poorly to medical therapy for at least 6 months and were poor surgical candidates were enrolled. Each participant was treated with rESWT once a week for 8 weeks, each by 2000 impulses at 2.0 bar and 10 hertz of frequency. International Prostate Symptom Score (IPSS), quality of life (QoL), and International Index of Erectile Function-5 (IIEF-5) were evaluated before treatment, after the fourth and eighth rESWT, and 3 months after the end of treatment. Peak urinary flow ( Q_max) and postvoid residual (PVR) were assessed. Safety was also documented. Statistically significant clinical improvements were reported for IPSS, QoL, and IIEF-5 after treatment, and those were sustained until 3 months follow-up. Q_max and PVR improved evidently at 8 weeks with a 63% and 70% improvement, respectively. The only adverse event was the occasional perineum pain or discomfort, which usually disappeared within 3 days. The rESWT may be an effective, safe, and noninvasive treatment for symptomatic BPH in selected patients whose medical treatment has faced failure and are poor surgical candidates.

The Collagenase of the Bacterium Clostridium histolyticum for the Treatment of Capsular Fibrosis after Silicone Implants

BACKGROUND

The main part of the fibrotic capsule in capsular contracture is collagen. The collagenase of the bacterium Clostridium histolyticum is U.S. Food and Drug Administration approved for the treatment of Dupuytren contracture and might be capable of dissolving the fibrotic capsule surrounding silicone implants.

METHODS

One hundred twenty days after insertion of miniature silicone implants the authors performed in vitro studies (n = 14) for optimum dosage-finding and subsequent in vivo studies (n = 36) to evaluate application method and efficiency. Data analysis involved histologic measurements of capsule thickness and collagen density; 7-T magnetic resonance imaging-based in vivo imaging; and polymerase chain reaction analysis of inflammatory, profibrotic, and antifibrotic markers.

RESULTS

Compared with the control group, each dosage showed significantly thinner capsules after in vitro incubation. Skin digestion occurred in 0, 1 (7 percent), and 11 cases (80 percent) after incubation with 0.3, 0.9, and 1.8 mg/ml, respectively. In vivo application showed a dosage-dependent decrease in capsule formation, which was more prominent in lower capsule parts, seen by magnetic resonance imaging. In vivo skin perforation was seen in two (17 percent) and six cases (50 percent) after injection of 0.3 mg/ml and 0.9 mg/ml, respectively. Profibrotic and inflammatory markers were significantly up-regulated 10 days after collagenase injection.

CONCLUSIONS

The collagenase of C. histolyticum is capable of dissolving the fibrotic capsule surrounding silicone implants. Skin perforation occurred most likely because of mechanical irritation after complete digestion of the capsule. Further studies are required to pave the way for safe clinical application.

Multiple extracorporeal shock wave therapy degrades capsular fibrosis after insertion of silicone implants

Capsular fibrosis is the most frequent long-term complication after insertion of silicone devices. Today, mainly direct immunostimulation and subclinical infection are held responsible for inducing and maintaining inflammatory reactions, which lead to overwhelming extracellular matrix formation. Extracorporeal shock waves (ESWs) are capable of inhibiting inflammatory processes and revealing antibacterial capacity. In our previous study, we observed decelerated capsule development after application of a single shock wave immediately after surgery. The purpose of this study was to evaluate the effects of multiple ESWT after insertion of silicone implants in the same rodent model. Therefore, silicone prostheses were inserted into a submuscular pocket in 12 additional male Lewis rats, and shock waves were administered over a 14-d interval. At 35 d (n = 6) and 100 d (n = 6) after insertion, silicone implants and surrounding capsule tissue were removed and prepared for histologic and immunohistochemical analysis, as well as polymerase chain reaction (Ccl2, CD68, transforming growth factor β1, matrix metalloproteinase 2). Compared with the control group, multiple ESWT had no effect on day 35, but resulted in a significantly thinner capsule on day 100 (825.8 ± 313.2 vs. 813.3 ± 47.9, p = 0.759, and 1062.3 ± 151.9 vs. 495.4 ± 220.4, p < 0.001, respectively). The capsule was even thinner than after a single shock wave application, which had been found to result in thinner capsules at every time point in our previous study. This active degradation of the fibrous envelope caused by multiple ESWs was accompanied by synergistic alterations in pro- and anti-fibrotic proteins (transforming growth factor β1 and matrix metalloproteinase 2, respectively). In conclusion, after insertion of silicone devices, single ESWT is capable of decelerating capsule formation in contrast to multiple ESWT, which degrades fibrotic tissue. These findings seem to be associated with inhibition of inflammation and beneficial effects on pro- and anti-fibrotic proteins.
