New Viscoelastic Hydrogel Hymovis MO.RE. Single Intra-articular Injection for the Treatment of Knee Osteoarthritis in Sportsmen: Safety and Efficacy Study Results.

Front Pharmacol 2021 28;12:673988. Epub 2021 May 28.

Department of Anatomical and Histological Sciences, Legal Medicine and Orthopedics, Sapienza University of Rome, Rome, Italy.

Viscosupplementation by hyaluronic acid (HA) is recommended for non-surgical management of knee osteoarthritis (OA). This study investigated the efficacy and safety of a single i.a. (32 mg/4 ml) Hymovis MO.RE. injection, a new HA derivative hydrogel, for the treatment of adult regular sports players affected by knee OA arising from overuse injuries. Patients were prospectively enrolled if regularly practicing sports and diagnosed with Kellgren-Lawrence grade I-III OA. They received a single Hymovis MO.RE. intra-articular (i.a.) injection and were evaluated 30, 90, 180, and 360 days thereafter. The assessment involved measuring changes in knee function, pain, the activity of daily living (ADL), and quality of life (QOL) by using the Knee injury and Osteoarthritis Outcome Score (KOOS), GAIT analysis, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores for knee pain (WOMAC A) and function (WOMAC C), and a visual analogue scale (VAS) pain score. The study involved thirty-one patients, 23 women and eight men, whose median age was 49. KOOS function subscore, as well as GAIT cadence and velocity, showed a statistically significant increase at each time-point after injection ( < 0.0001). WOMAC, KOOS pain, symptoms, ADL, and QOL scores also significantly improved at all control visits. No severe adverse events or treatment-related events were detected. A single Hymovis MO.RE. (32 mg/4 ml) intra-articular injection provides a rapid, lasting, and safe response in regular sports players affected by knee OA, possibly representing a viable therapeutic option for this demanding patient subgroup. Further investigations are necessary to confirm these findings.

Clinical effectiveness and safety of intra-articular injection of HYALGO in the management of knee osteoarthritis symptoms: A multicenter prospective study.

J Clin Orthop Trauma 2021 Aug 15;19:75-80. Epub 2021 May 15.

Medical Plus, Uherské Hradiště, Czech Republic.

Background: The reduced concentration of hyaluronic acid in the synovial fluid, leading to impairment of joint function and painful symptomatology during knee osteoarthritis (OA), can be restored by using injectable formulations of hyaluronic acid (HA) and chondroitin sulfate (CS), variable for relative composition, HA/CS molecular modifications, and injection protocols. The present study aims to assess the safety and performance of the intra-articular (IA) viscosupplementing agent HYALGO, a formulation combining 40 mg/mL HA (>1700 kDa) and 40 mg/mL CS, in the treatment of patients suffering from knee OA.

Methods: 74 patients affected by knee lesions classified as grade II and III according to Kellgren and Lawrence classification were prospectively recruited and treated with three HYALGO injections (2 mL) given one week apart. Visual analogue scale (VAS) pain changes were monitored at each injection and over-time at 6, 14, and 26 weeks of follow-up. Secondary endpoints were: Western Ontario McMaster University Osteoarthritis index (WOMAC), Patient's Global Assessment (PGA) score, Clinical Observer Global Assessment (COGA) score, Outcome Measures in Rheumatology Committee (OMERACT) and Osteoarthritis Research Society International (OARSI) responders rates. Patients were also assessed for changes in their ultrasound joint scores according to the criteria of the OMERACT US Task Force Group.

Results: Pain reduction was statistically significant starting from the first IA injection. Mean pain reduction from baseline to week 26 was -90.6%. At 26 weeks, WOMAC Pain was reduced by -62.7%, WOMAC Stiffness by -47.2%, WOMAC Physical Function by -54.1%; Total WOMAC by -53.8%. The VAS PGA change from baseline was -48.0 [mm] and VAS COGA -41.0 [mm]. Responders at week 26 were 78.4%. Ultrasound parameters (joint effusion, synovial thickness, and popliteal cysts) improved or remained stable from baseline to week 6.

Conclusions: Three injections of HYALGO were safe and effective to manage symptomatic knee OA, with a beneficial effect that increased progressively over time, peaking 6 months after injection.

Treatment of vulvo-vaginal atrophy with hyaluronate-based gel: a randomized controlled study.

Minerva Obstet Gynecol 2021 Jun 7. Epub 2021 Jun 7.

Fidia Farmaceutici, S.p.A., Abano Terme, Padua, Italy.

Background: The study aimed to assess the performance and safety of single-use applicators prefilled with hyaluronic acid (HA)-based vaginal gel (Hyalo Gyn) for the treatment of vulvovaginal atrophy (VVA)-related signs and symptoms in postmenopausal women.

Methods: Eighty women were randomized, 46 to Hyalo Gyn gel and 34 to a standard treatment (water-based lubricant). Outcome data collected included: the proportion of subjects having a reduction ≥1 point in the Verbal Rating Scale (VRS) dryness score, VRS global score, vaginal pH, Vaginal Health Index (VHI), Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), patients' global assessment, tolerability, and safety.

Results: Significant improvements were observed for all the assessed endpoints in both treatment groups. The perception of any improvement on the VRS dryness score was not statistically different between the treatment groups. A sensitivity analysis on the absolute change in VRS dryness score showed a statistically significant difference in favor of the Hyalo Gyn group at 3 months.

Conclusions: A 3-month treatment with Hyalo Gyn gel is effective, safe, and well tolerated for VVA-related symptoms in post-menopausal women.

Hyaluronic acid and metallic silver treatment of chronic wounds: healing rate and bacterial load control.

J Wound Care 2019 Jul;28(7):482-490

Fidia Farmaceutici S.p.A, Abano, Italy.

Objective: To confirm the safety and wound healing activity of a topical spray powder containing hyaluronic acid (HA) and metallic silver (Hyalosilver, Fidia Farmaceutici S.p.A., Italy), and investigate its effect on the control of bacterial load in vascular ulcers or category I-II pressure ulcers (PU).

Methods: This is a single site, prospective, open label study involving patients with a vascular ulcer or category I-II PUs, presenting signs of critical bacterial colonisation. Patients with a wound size of ≤15cm were enrolled. At baseline, a swab was taken of each wound for a semi-quantitative analysis of bacterial load and the first treatment of topical spray powder was applied. The patient was then requested to self-apply the medication once a day for 28 consecutive days and to return on days one, seven and 28 for clinical and microbiological assessments.

Results: A total of 25 patients were enrolled in the study. Treatment with the topical spray powder enhanced the healing rate of chronic wounds in terms of a reduction of wound area as well as bacterial load (p<0.025) and the overall clinical status of wound (odour, exudate, erythema of periwound skin; p<0.017). Moreover, the spray powder increased overall patient perception of improvement in the wound (p<0.05).

Conclusion: The data demonstrated good safety and tolerability of the topical spray powder suggesting that the product is effective not only in reducing wound area, due to the presence of HA, but in keeping the bacterial colonisation under control.

Hyaluronan derivative HYMOVIS® increases cartilage volume and type ii collagen turnover in osteoarhritic knee: data from MOKHA study.

BMC Musculoskelet Disord 2019 Jun 18;20(1):293. Epub 2019 Jun 18.

Service de Rhumatologie - Centre Viggo Petersen, Hôpital Lariboisière, Paris, France.

Background: The objective of this pilot study was to identify biological, clinical or structural biomarkers of an intra-articular hyaluronic acid injection efficacy (HYMOVIS®) for the design of a larger placebo-controlled clinical trial studying the disease-modifying activity of this treatment.

Methods: Forty six patients with symptomatic knee Osteoarthritis (OA) were enrolled in this open-label, prospective, multicenter, pilot study. Patients received two treatment cycles of intra-articular injections (3 mL) of HYMOVIS® (8 mg/mL of hyaluronic acid hexadecylamide) at 6 months interval. Each treatment cycle involved two intra-articular injections 1 week apart. All patients had Magnetic Resonance Imaging (MRI) of the target knee at baseline and 1 year, and blood samples to assess joint biomarkers. The primary outcome was the change in type II collagen-specific biomarkers (Coll2-1, Coll2-1NO2 and CTX-II) after HYMOVIS® treatment versus baseline. Secondary endpoints included levels changes in aggrecan chondroitin sulfate 846 epitope (CS-846), Cartilage Oligomeric Matrix Protein (COMP), procollagen type II N-terminal propeptide (PIIANP), Matrix Metalloprotease (MMP)-3, Myeloperoxidase (MPO) and Interleukin (IL)-6 serum biomarkers, the ratio Coll2-1/PIIANP, CTX-II/PIIANP, variation of MRI cartilage volume, and Knee injury and Osteoarthritis Outcome Score (KOOS) index.

Results: Coll2-1 serum levels significantly increased overtime while Coll2-1NO2 levels were only increased at D360. Serum PIIANP levels also progressively and significantly enhanced with time. In contrast, other serum biomarker levels including CTX-II, CS-846, COMP, MMP-3, MPO or IL-6 did not change significantly overtime. Interestingly, the ratios Coll2-1/PIIANP and CTX-II/PIIANP decreased, indicating a decrease of cartilage catabolism. Compared to baseline value, MRI cartilage volume and thickness increased in lateral femoral and lateral trochlea compartments and not in medial compartment. These results, in addition to an improvement of T2 mapping score suggest a positive structural effect of the product. Interestingly, WORMS effusion score, an indicator of synovitis, significantly decreased. Finally, global KOOS score and subscales significantly increased overtime while pain at rest, walking pain and patients or investigators global assessment of disease activity decreased. The safety profile was favorable with a low incidence of injection-site pain.

Conclusion: HYMOVIS®, a well-tolerated intra-articular treatment, significantly enhanced type II collagen turnover as suggested by the increase in Coll2-1 and PIIANP levels and cartilage volume observed by MRI in lateral knee compartment. Importantly, this study provides critical information for the design of a larger phase III clinical trial investigating Disease Modifying effect of HYMOVIS®.

Randomized Double-Blind Controlled Study on the Safety and Efficacy of a Novel Injectable Cross-linked Hyaluronic Gel for the Correction of Moderate-to-Severe Nasolabial Wrinkles.

Aesthetic Plast Surg 2019 04 3;43(2):470-479. Epub 2019 Jan 3.

Department of Surgery "P.Valdoni", UOC of Plastic Surgery, Sapienza University of Rome, Policlinico Umberto I, Rome, Italy.

Introduction: The current study compares two hyaluronic acid fillers, Ial System Duo and Belotero Basic/Balance, for the treatment of wrinkles.

Materials And Methods: This is a single-center, double-blind randomized controlled study. Inclusion criteria consisted of subjects with bilateral nasolabial wrinkles. Each subject was treated with both products: One was applied on the right side and the other on the left side of the face. The quantity of product injected and any problems or local reactions (erythema, edema, pain or itching) were recorded and reassessed at 3 and 6 months and then monthly until complete absorption of the product. The Wrinkle Severity Rating Scale (WSRS) and the Global Aesthetic Improvement Scale (GAIS) were used for the assessment, as well as an ultrasound measurement of the skin thickness.

Results: Complete data were available for 59 subjects. At 3 and 6 months, both products showed improvement in the WSRS and GAIS score in the areas treated compared to pre-treatment assessments, although no significant differences were observed between them. No resulting significant differences were observed on skin thickness among the two products, which were completely reabsorbed in 285 ± 34 days (Ial System Duo) and 277 ± 34 days (Belotero Basic/Balance; Student's t test: p = 0.2181). No significant differences were observed with regard to the subject's satisfaction and adverse events.

Conclusions: The Ial System Duo achieves long-term permanence (more than 9 months confirmed by ultrasound) in correction of moderate and severe wrinkles, similar to Belotero Basic/Balance. Both products showed a high safety profile and a high degree of subject and physician satisfaction.

Efficacy and safety of hyaluronic acid (500-730kDa) Ultrasound-guided injections on painful tendinopathies: a prospective, open label, clinical study.

Muscles Ligaments Tendons J 2017 Apr-Jun;7(2):388-395. Epub 2017 Sep 18.

Department of Biomedical Sciences, University of Ferrara, Ferrara, Italy.

Background: Tendinopathies are conditions characterized by activity-induced pain, local tenderness and swelling for which a gold standard treatment is not established yet. Hyaluronic Acid (HA) is a key-molecule in several cellular activities and it is normally present in the extra-cellular matrix of tendons and ligaments. Amongst its properties, HA injections may reduce pain and determine disease-modifying effects. This study is an investigator-initiated open-label trial conducted to investigate the efficacy and safety of HA (500-730 kDa) peritendinous injections on pain reduction in patients affected by lateral elbow, Achilles or patellar tendinopathy.

Methods: A total of 71 tendons (34 with Achilles tendinopathy, 26 with lateral elbow tendinopathy, 11 with patellar tendinopathy) of 62 patients with painful tendinopathy were treated with a cycle of ultrasound-guided peritendinous injections one injection per week for three consecutive weeks. Efficacy assessments included changes in pain intensity measured by Visual Analogue Scale (VAS) at follow-up evaluations were performed 7 (V2), 14 (V3) and 56 days aften first treatment. An Ultrasound (US) assessment was also performed to evaluate changes in tendon thickness and neovascularization. Adverse events were recorded for safety analysis throughout the study. All results were analyzed with descriptive statistics appropriate to the nature of the variables.

Results: Significant reduction in VAS (p<0.001) from baseline was observed in Achilles (-6.16 ± 0.45 cm), patellar (-6.16 ± 0.72 cm) and lateral elbow (-5.33 ± 0.43 cm) tendinopathies. The sagittal thickness decreased significantly from baseline at each endpoint (V3 day 14 and V4 day 56) in each type of tendinopathy analyzed (p<0.05). Neovascularization decreased for each tendons at V3 and V4, except for patellar tendon at V3 V1 (p=0.125). Nevertheless, reduction at V4 compared to baseline remained significant (p=0.016).

Conclusions: US-guided HA (500-730 kDa) peritendinous injections determine significant pain relief and reduction in tendon thickness and neovascularization in US evaluations. The effect of HA did not show differences regarding the site of affected tendon. The treatment proved to be safe and very well tolerated.

A new hydrogel for the conservative treatment of meniscal lesions: a randomized controlled study.

Joints 2015 Jul-Sep;3(3):136-45. Epub 2016 Jan 28.

Department of Orthopaedics, Sacro Cuore Hospital of Negrar, Negrar (VR), Italy.

Purpose: this study aimed to investigate the efficacy of intra-articular (IA) administration of a hydrogel formulation obtained from a hyaluronic acid (HA) derivative (HYADD4(®)) in the management of meniscal tears and in meniscal tear repair.

Methods: fifty subjects with degenerative meniscal tears were enrolled into this single-site, observer-blind, parallel-group study. Clinical evaluations were performed at baseline and after 14, 30 and 60 days. Clinical outcomes included: pain reduction (Visual Analog Scale), improvement of knee functionality (WOMAC questionnaire), reduction in length and depth of the meniscal lesion (MRI-confirmed) and SF-36 questionnaire scores. Local tolerability and safety were also investigated.

Results: a significant reduction in VAS pain (p< 0.001) in favor of HYADD4(®) was recorded at day 14 and maintained at all the follow-up assessments. Data on knee functionality were in line with the VAS pain assessment results. A significant reduction in length and depth of the meniscal lesion, assessed using MRI, was found in the HYADD4(®) group compared to the control group (p<0.001).

Conclusions: the results of this study may indicate a new treatment option in the conservative management of patients complaining of pain due to meniscal tears. The MRI data suggest that the hydrogel formulation of HA used in this study may also play a role in the healing process of the lesion.

Intra-articular glenohumeral injections of HYADD®4-G for the treatment of painful shoulder osteoarthritis: a prospective multicenter, open-label trial.

Joints 2015 Jul-Sep;3(3):116-21. Epub 2016 Jan 28.

Unit of Orthopaedics, Istituto Clinico Humanitas, Rozzano (MI), Italy.

Purpose: numerous experimental and clinical studies in osteoarthritis (OA) have demonstrated that intra-articular (IA) administration of hyaluronic acid can improve the altered rheological properties of the synovial fluid and exert protective and reparative effects on the joint structure. The objective of this study was to evaluate the safety and performance of HYADD®4-G (Hymovis®) in patients with glenohumeral joint OA.

Methods: forty-one patients with shoulder pain and limited shoulder function resulting from concentric glenohumeral joint OA were enrolled in a multicenter clinical trial. Patients received two HYADD®4-G injections administered one week apart. The main outcome measure was improvement in shoulder pain on movement at six months as assessed through a 100-mm visual analog scale (VAS), range of motion (ROM) values, and Constant-Murley Shoulder Outcome Score (CS).

Results: two IA injections of HYADD®4-G (Hymovis®) significantly decreased pain and improved shoulder function for up to six months from the first injection. The VAS score decreased (from 66.1 mm to 37.7 mm at six months) and improvements were recorded in the total CS and in the ROM values ( rotation decreased from a mean value of 54.2° at baseline to 63.2° at six months and internal rotation from a mean value of 44.0° at baseline to 45.7° at 26 weeks). No serious adverse events occurred.

Conclusions: the study results demonstrated that two IA injections of HYADD®4-G (Hymovis®) may be a safe and effective treatment option for shoulder pain associated with glenohumeral OA and that the effects of the injections are still present for up to six months after the treatment.

J Sports Med Phys Fitness 2016 Jan-Feb;56(1-2):92-9. Epub 2015 May 27.

German Sports University, Institute of Sports Medicine, Köln, Germany -

Background: This study aimed to assess the efficacy and the safety of a newly-developed patch containing diclofenac sodium 140 mg in patients affected by acute soft tissue sport injuries, such as contusion, strain and sprain with a randomised, double-blind, placebo-controlled trial.

Methods: One hundred and sixty-four subjects were recruited within 3 hours of a soft-tissue sport injury and were equally assigned to receive diclofenac or placebo patch applied twice a day for 7 days. The primary study endpoint was reduction in severity of pain on movement from baseline to 48 hours measured by Visual Analogue Scale. Secondary outcomes were reduction of pain on movement and at rest, reduction of pain on pressure, time to efficacy onset, global efficacy assessment and use of rescue analgesics.

Results: The reduction of pain on movement from baseline to day 2 was markedly greater in the diclofenac group compared with placebo (treatment effect: -24.25 mm, P<0.001 between groups). Statistically significant improvements were also observed in the diclofenac group compared to placebo for the secondary variables of pain on movement and at rest, pain on pressure, time to efficacy onset and global patient and investigator efficacy assessment. Local adverse reactions at the application site were reported in comparable rates in the two groups.

Conclusions: The diclofenac patch could be a safe and effective alternative to the oral administration of non-steroidal anti-inflammatory drugs in the treatment of minor sport injuries.

b Department of Plastic , Reconstructive and Aesthetic Surgery, 'Sapienza' University , Policlinico 'Umberto I', Rome , Italy.

Objectives: The present study aimed to evaluate the effectiveness and safety of hyaluronic acid gel for the treatment of volume loss or contour deficiency.

Methods: This 6-month, open-label study recruited sixty adults aged 40-65 years with bilateral moderate to severe volume loss or contour deficiency (Facial Volume Loss Scale [FVLS] score: 2-5). Eligible subjects were treated at the baseline visit with an injection of hyaluronic acid gel in one or more of three facial subregions: the zygomatic malar region, the anteromedial cheek and nasolabial folds.

Results: A significant improvement from baseline was observed in the FVLS score at each study visit up to 6 months post treatment (p < 0.0125 by Wilcoxon test). A significant improvement was also observed in the Global Aesthetic Improvement Scale (GAIS) at each visit up to 6 months. The study showed that the GAIS score improved in 100% of subjects at month 3, while at the end of the study (month 6) the percentage of improved subjects decreased to 91. Treatment effect was maintained by 100% of subjects up to month 3, while 57% of subjects showed a persistence of effect up to month 6.

Conclusions: Volume loss or contour deficiency may be safely and effectively corrected using the new dermal filler.

A new dermal filler made of cross-linked and auto-cross-linked hyaluronic acid in the correction of facial aging defects.

J Cosmet Dermatol 2014 Dec;13(4):307-14

Derming, Clinical Research and Bioengineering Institute, Monza, MB, Italy.

Background: A novel Hyaluronic Acid (HA) derivative dermal filler has been developed with characteristics especially suited for nasolabial folds (NLF) and facial defects due to volume loss.

Aims: An open-label prospective study was carried out to evaluate this HA filler's performance in correcting facial defects due to volume loss.

Methods: A single Italian site treated subjects aged 30-65 for facial defects due to volume loss with a new dermal filler injectable gel; subjects returned to the clinic at 7 and 14 days, and 1, 3, 6, 9, and 12 months for follow-up. The primary effectiveness endpoint was improvement in wrinkle severity (measured using the Wrinkle Severity Rating Scale) (WSRS) and facial volume (measured using the Facial Volume Loss Scale) (FVLS) at 6 and 12 months from baseline. Secondary endpoints were safety evaluation, performance duration, product handling, subjects' and investigator's treatment evaluation. Assessment of aesthetic results included the skin hydration, image analysis of nasolabial folds (3D), and photographic documentation.

Results: The reduction in nasolabial wrinkles was statistically significant at 6 months after the first implant. The aesthetic improvement of 1 grade on WSRS was evident in 95% of subjects up to 3 months, in 84% of subjects up to 6 months and in 27% up to 12 months. A clinically (> 1 point improvement) and statistically significant improvement in the FVLS was observed at each study visit; in 100% of treated cases, up to 3 months and in 61% up to 9 months. Good results were obtained during the study in skin hydration. There were no severe adverse events related to treatment.

Conclusion: This injectable gel is well tolerated and has been demonstrated to provide a smooth and natural improvement in facial defects due to volume loss in nasolabial folds and the malar region that lasts for up to 1 year.

Evaluation of the efficacy and safety of hyaluronic acid vaginal gel to ease vaginal dryness: a multicenter, randomized, controlled, open-label, parallel-group, clinical trial.

J Sex Med 2013 Jun 9;10(6):1575-84. Epub 2013 Apr 9.

Department of Obstetrics and Gynecology, Peking University First Hospital, Beijing, China.

Introduction: Atrophic vaginitis is a common occurrence, particularly among postmenopausal women; however, few seek or receive treatment. One therapeutic solution is topically applied products. Estrogen-based treatments have been shown to be effective; however, many patients are reluctant to use such formulations due to health concerns, hence the need to assess the efficacy of acceptable alternatives.

Aim: This multicenter, randomized, controlled, open-label, parallel-group clinical trial set out to evaluate the efficacy and safety of hyaluronic acid vaginal gel to treat vaginal dryness compared with estriol cream in postmenopausal women.

Methods: One hundred forty-four subjects were randomized, 72 to the test group treated with hyaluronic acid vaginal gel (Hyalofemme) and 72 to the control group treated with estriol cream (Ovestin). Treatment in both groups was applied by means of a device once every 3 days for a total of 10 applications over 30 days.

Main Outcome Measures: Efficacy was measured by grading vaginal dryness and three other vaginal symptoms on a visual analog scale. Safety assessments included vital signs, laboratory examinations of the vaginal microecosystem, vaginal pH value, vaginal B ultrasound, and incidence of adverse events. Assessments were performed at baseline, by telephone after the third application, and at the final visit.

Results: Both hyaluronic acid vaginal gel and estriol cream can significantly improve the clinical symptoms of vaginal dryness in postmenopausal women, with improvement rate of 84.44% and 89.42%, respectively, after 10 applications, without statistically significant difference between them.

Conclusion: Both hyaluronic acid vaginal gel and estriol cream are effective in the treatment of vaginal dryness. Hyaluronic acid vaginal gel may be considered as a valid alternative to estrogen-based treatments in relieving the symptoms of vaginal dryness.

The use of Hyalomatrix PA in the treatment of deep partial-thickness burns.

J Burn Care Res 2007 Mar-Apr;28(2):269-74

Department of Surgery, University of Rome Tor Vergata, Italy.

Since 2001, Hyalomatrix PA (Fidia Advanced Biopolymers, Abano Terme, Italy) has been used in our center on pediatric burned patients as a temporary dermal substitute to cover deep partial-thickness burns after dermabrasion. This "bridge" treatment was adopted to remove necrotic debris (dermabrasion) and to stimulate regeneration in a humid and protected environment (Hyalomatrix PA). We present results obtained with this approach. On the third to fifth day after admission, dermabrasion was practiced on deep burned areas, which were covered with Hyalomatrix PA. Change of dressings was performed every 7 days. On day 21, those areas still without signs of recovery were removed with classic escharectomy and covered with thin skin grafts. We treated 300 patients. Sixty-one percent needed only one dermabrasion treatment, 22.3% (67 patients) more than one, and 16.7% (50 patients) the classic escharectomy. A total of 83% of patients healed within 21 days. Our study suggests that the combination of dermabrasion with a temporary dermal substitute could be a good and feasible approach for treatment of deep partial-thickness burns. Prospective randomized studies are now necessary to compare our protocol with the gold standard treatment of topical dressings.
