Effects of soft tissue mobilisation on subacute adherent linear scars: a single-group intervention study.

OBJECTIVE: Scar adherence due to a pathological healing process can cause physical and psychological disturbance. Soft tissue mobilisation (STM) techniques are widely used to treat and prevent scar adherence, but little is known on their effects. We aimed to analyse the effect of STM in patients with subacute post-surgical scar adhesions affecting the extremities. METHOD: A single-group quasi-experimental study was conducted on consecutive patients undergoing post-surgery limb rehabilitation. Patients with a baseline Adhesion Severity (AS) index of <0.5 at the worst scar point, as measured by the Adheremeter, were eligible. All patients who completed a minimum of five manual treatment sessions were included. The primary outcome was the AS index and the secondary outcome was the Italian version of the Patient and Observer Scar Assessment Scales (POSAS-I). RESULTS: A cohort of 19 patients underwent an average of eight STM sessions over a period of one month. The AS index value increased from a median of 0.12 at baseline (interquartile range (IQR): 0.05-0.25) to 0.41 post-treatment (IQR: 0.26-0.63; median change: 0.24; IQR: 0.16-0.40; p<0.001). A large effect size was observed for both AS and Observer Scar Assessment Scale (OSAS-I) (Cohen r=0.6), with a large probability of superiority (PS) (87% and 86%, respectively). A moderate effect was observed for the Patient Scar Assessment Scale (PSAS-I) (Cohen=0.4; PS=71%). Pre-post treatment changes exceeded the minimal detectable changes for the AS and OSAS-I in 68% of subjects, and for PSAS-I in 21% of subjects. CONCLUSION: STM manual techniques may produce a large effect on the mobility of adherent subacute post-surgical scars.

Clinical Outcomes of Utilizing a "W"-shaped Incision in the Management of Forehead Skin Thickening Induced by Hypertrophic Osteoarthropathy.

BACKGROUND: Hypertrophic osteoarthropathy (HOA) is a rare and intricate hereditary disease. The appearance and functional deformity of the forehead caused by thickened folds are the main clinical manifestations of patients with hypertrophic osteoarthropathy. The cause of this disease is still unknown. Currently, surgical treatment has become one of the best strategies, mainly for improving the appearance of the forehead. There has been no literature report on the use of "W"-shaped skin flap resection for thickened forehead skin in patients with hypertrophic osteoarthropathy. METHODS: All cases of hypertrophic osteoarthropathy in our department in the last 7 years, and previous literature on hypertrophic osteoarthropathy, were reviewed. RESULTS: A total of 5 cases of hypertrophic osteoarthropathy in our department (mean age 21 years, all male patients) were reviewed. All patients underwent open surgery to remove the thickened skin on the forehead or the wrinkles and gyrus-shaped scalp. The jagged skin tissue was removed (8-9) cm × (1-2.5) cm × 0.5 cm. The folds and thickness of the frontal skin of the patients were greatly improved after the operation. Patient satisfaction with the treatment outcomes was unanimous. However, one case experienced a postoperative wound infection during follow-up. The utilization of the "W"-shaped excision technique allowed for the maximal removal of excessively diseased tissue, thereby facilitating a smoother resolution of the depression. CONCLUSIONS: A total of 5 cases of hypertrophic osteoarthropathy were treated in our department, and all of them underwent frontal skin "W"-shaped excision, which was safe, feasible, and practical, and the postoperative results were satisfactory.

Morphological characteristics of facial scars: A retrospective analysis according to scar location, onset, age, and cause.

The morphology of facial scars shows a wide variation in terms of texture and colour. To date, there are no reliable predictors of aberrant scarring. We conducted a retrospective analysis to identify factors associated with specific scar features and types. Photographs and medical records of 428 patients with facial scars were retrospectively reviewed. Patients with keloids were excluded. The mean age of the patients was 45.43 ± 23.13 years with a male-to-female ratio of 1:1.36. Atrophic scars were the most common (42.8%), followed by flat scars (38.7%) and hypertrophic scars (18.5%). Scars on the forehead were more likely to be atrophic, whereas scars on the chin/jaw and around the mouth were more likely to be hypertrophic. Hypopigmentation was significantly more common in scars located on the forehead. Redness (erythema) was significantly more common in scars located on the chin/jaw. Old scars were less likely to be erythematous, and hypertrophic. Atrophic scars were more common in younger patients. Scars caused by dermatologic conditions, such as acne, were more likely to be atrophic, whereas surgical scars had the lowest risk of being atrophic or hypertrophic. In conclusion, the location, onset, and cause of facial scars were associated with specific features of scars.

A Comparative study between the efficacy of combined Intense Pulsed Light plus high-intensity focussed ultrasound in the treatment of atrophic and icepick scars.

OBJECTIVE: To investigate the efficiency of high-intensity focussed ultrasound with intense pulsed light in the treatment of atrophic and icepick acne scars. METHODS: The interventional study was conducted between November 2021 and April 2022 at the Postgraduate Medical Physics Laboratory, Mustansiriyah University, Baghdad, Iraq, and comprised patients with atrophic scars in group A and acne scars in group B. They were treated first with intense pulsed light and then with high-intensity focussed ultrasound. All patients received 4 treatment sessions spread over 4 weeks. Outcome assessment was done using Patient and Observer Scar Assessment Scale. Data was analysed using SPSS software version 24. RESULTS: Of the 22 patients, 12(55%) were males with mean age 20.75±4.20 years, and 10(45%) were females with mean age 21±2.05 years. The combination technique showed significant outcomes compared to baseline (p<0.05). Atrophic scars exhibited significantly greater improvement compared to icepick scars (p<0.05). There was no significant difference between the overall opinion of the observer (p=0.3549) and the patients (p=0.0956). CONCLUSIONS: The high-intensity focussed ultrasound and intense pulsed light techniques used in combination was found to be effective in treating atrophic and icepick scars.

Scar outcomes for conservatively managed children post burn injury: A retrospective study.

Hypertrophic scarring is a significant complication post burn injury, especially for delayed healing after 3 weeks. Burn injuries healing prior to 3 weeks also have the potential to develop hypertrophic scarring, even when prescribed prophylactic conservative scar interventions. A retrospective chart audit reviewed 326 burn patients treated at a paediatric tertiary hospital from 2014 to 2019 who sustained a partial thickness burn, healed >14 days and did not receive skin grafting. A scar was deemed hypertrophic if >1 mm in height. Early hypertrophic scar prevalence was defined as 3-6 months post burn, while persistent hypertrophic scarring was defined as 12-18 months post burn. Median days to wound closure was 18. The prevalence of early and persistent hypertrophic scarring was 56.1% and 16.3%, respectively. Seventeen (5.2%) children underwent medical interventions for scar modulation. Early signs of hypertrophic scarring were seen in just over half the patients presenting to burn therapy and despite scar intervention, persistent hypertrophic scarring was seen in 16.3%. At both time points, just over half of the children presenting healed between 14 and 21 days. Therefore, children healing prior to 21 days have potential to develop hypertrophic scarring.

The efficacy of combined Intense pulsed light plus high-intensity focussed ultrasound with two different powers in the treatment of atrophic and Icepick acne scars.

OBJECTIVE: To determine the clinical efficacy and suitable power of high-intensity focussed ultrasound combined with intense pulsed light to treat acne scarring. METHODS: The prospective study was conducted at the College of Medicine, Mustansiriyah University, Baghdad, Iraq, from September 2020 to March 2021, and comprised patients of either gender with atrophic or icepick scars. They were divided into atrophic scar group A and icepick scar group B. Both groups were first treated with intense pulsed light and then with high-intensity focussed ultrasound using 30J/cm2 and 40J/cm2 power. There were overall 4 sessions with an interval of 4 weeks. The outcome was assessed using the Patient and Observer Scar Assessment Scale. Data was analysed using SPSS 25. RESULTS: Of the 22 patients with a mean age of 20.86±3.22 years, there were 11patients in group A; 7(70%) females and 4(30%) males with a mean age of 20.5±2.06 years. There were 11patients in group B; 7(70%) males and 4(30%) females with a mean age of 21.27±4.19 years. There was a significant difference between baseline and postintervention scores for both groups (p<0.05), and power 30J/cm2 was significantly better compared to 40J/cm2 (p<0.05). CONCLUSIONS: The developing technique using high-intensity focussed ultrasound and intense pulsed light was found to be effective in treating scars with 30J/cm2 power.

Parecoxib decreases cellular growth and Bcl-2 protein levels in primary cultures of keloid fibroblasts.

Keloids seem to overexpress cyclo-oxygenase-2 (COX-2), suggesting a role in its deregulated pathway in inducing an altered epithelial-mesenchymal interaction, which may be responsible for the overgrowth of dermal components resulting in scars or keloid lesions. This study aimed to evaluate the effect of Parecoxib, a COX-2 inhibitor, on cell growth in fibroblast primary cultures obtained from human keloid tissues. Tissue explants were obtained from patients who underwent intralesional excision of untreated keloids; central fractions were isolated from keloid tissues and used for establishing distinct primary cultures. Appropriate aliquots of Parecoxib, a COX-2 inhibitor were diluted to obtain the concentration used in the experimental protocols in vitro (1, 10 or 100 µM). Treatment with Parecoxib (at all concentrations) caused a significant decrease in cellular growth from 24 hours onwards, and with a maximum at 72 hours (P < .02). Moreover, at 72 hours Parecoxib significantly reduced cellular vitality. Parecoxib treatment also induced an increase in fragmented nuclei with a maximum effect at 100 µM and a significant decrease in Bcl-2 and an increase in activated caspase-3 protein levels at 72 hours compared with control untreated cultures. Our findings suggest a potential use of the COX-2 inhibitor, Parecoxib, as the therapy for keloids.

Artificial Intelligence for Contrast-Free MRI: Scar Assessment in Myocardial Infarction Using Deep Learning-Based Virtual Native Enhancement.

BACKGROUND: Myocardial scars are assessed noninvasively using cardiovascular magnetic resonance late gadolinium enhancement (LGE) as an imaging gold standard. A contrast-free approach would provide many advantages, including a faster and cheaper scan without contrast-associated problems. METHODS: Virtual native enhancement (VNE) is a novel technology that can produce virtual LGE-like images without the need for contrast. VNE combines cine imaging and native T1 maps to produce LGE-like images using artificial intelligence. VNE was developed for patients with previous myocardial infarction from 4271 data sets (912 patients); each data set comprises slice position-matched cine, T1 maps, and LGE images. After quality control, 3002 data sets (775 patients) were used for development and 291 data sets (68 patients) for testing. The VNE generator was trained using generative adversarial networks, using 2 adversarial discriminators to improve the image quality. The left ventricle was contoured semiautomatically. Myocardial scar volume was quantified using the full width at half maximum method. Scar transmurality was measured using the centerline chord method and visualized on bull's-eye plots. Lesion quantification by VNE and LGE was compared using linear regression, Pearson correlation (R), and intraclass correlation coefficients. Proof-of-principle histopathologic comparison of VNE in a porcine model of myocardial infarction also was performed. RESULTS: VNE provided significantly better image quality than LGE on blinded analysis by 5 independent operators on 291 data sets (all P<0.001). VNE correlated strongly with LGE in quantifying scar size (R, 0.89; intraclass correlation coefficient, 0.94) and transmurality (R, 0.84; intraclass correlation coefficient, 0.90) in 66 patients (277 test data sets). Two cardiovascular magnetic resonance experts reviewed all test image slices and reported an overall accuracy of 84% for VNE in detecting scars when compared with LGE, with specificity of 100% and sensitivity of 77%. VNE also showed excellent visuospatial agreement with histopathology in 2 cases of a porcine model of myocardial infarction. CONCLUSIONS: VNE demonstrated high agreement with LGE cardiovascular magnetic resonance for myocardial scar assessment in patients with previous myocardial infarction in visuospatial distribution and lesion quantification with superior image quality. VNE is a potentially transformative artificial intelligence-based technology with promise in reducing scan times and costs, increasing clinical throughput, and improving the accessibility of cardiovascular magnetic resonance in the near future.

MicroRNAs involved in human skin burns, wound healing and scarring.

MicroRNAs are small, non-coding RNAs that regulate gene expression, and consequently protein synthesis. Downregulation and upregulation of miRNAs and their corresponding genes can alter cell apoptosis, proliferation, migration and fibroproliferative responses following a thermal injury. This review summarises the evidence for altered human miRNA expression post-burn, and during wound healing and scarring. In addition, the most relevant miRNA targets and their roles in potential pathways are described. Previous studies using molecular techniques have identified 197 miRNAs associated with human wound healing, burn wound healing and scarring. Five miRNAs alter the expression of fibroproliferative markers, proliferation and migration of fibroblasts and keratinocytes post-burn: hsa-miR-21 and hsa-miR-31 are increased after wounding, and hsa-miR-23b, hsa-miR-200b and hsa-let-7c are decreased. Four of these five miRNAs are associated with the TGF-ß pathway. In the future, large scale, in vivo, longitudinal human studies utilising a range of cell types, ethnicity and clinical healing outcomes are fundamental to identify burn wound healing and scarring specific markers. A comprehensive understanding of the underlying pathways will facilitate the development of clinical diagnostic or prognostic tools for better scar management and the identification of novel treatment targets for improved healing outcomes in burn patients.

Pleiotropic effect of intramucosal injection of FTY720 on angiogenesis and tissue healing after free gingival graft surgery: a comparative experimental study in rabbits.

OBJECTIVES: Free gingival graft surgery is the gold standard for increasing the size of keratinized tissue. Blood supply in the recipient site is critical for healing. Therefore, in this study, the effect of FTY720 on angiogenesis, healing, and scar tissue presence following free gingival graft surgery is investigated. MATERIALS AND METHODS: Surgeries were performed on 10 New Zealand white rabbits. Rabbits were randomly assigned to two groups. In the experimental group, immediately after surgery, 2 and 4 days later, FTY-720 was injected into the tissue surrounding the recipient site. In the control group, the same frequency of placebo vehicle was injected. After 30 days, tissue samples were assessed histologically and histomorphometrically. RESULTS: The blood vessel count (P < 0.000) and rete ridge formation (P < 0.05) in the experimental group were significantly higher, while the epithelial thickness was lower in this group (P < 0.000). There was no significant difference in the percentage of regions occupied by collagen fibres between the groups (P = 0.987). Furthermore, a significant and negative relationship between epithelial thickness and blood vessel count was shown (Pearson correlation coefficient = - 0.917). CONCLUSIONS: The findings indicate that the angiogenic effects of FTY-720 in the recipient site of free gingival graft can be employed to promote tissue healing and reduce scar tissue presence. CLINICAL RELEVANCE: A significant decrease in epithelial thickness and increase in angiogenesis as well as rete ridge formation score in the FTY-720 group were shown, which can be translated into improved tissue healing and less presence of scar tissue.

Needlescopic Primary Paediatric Inguinal Hernia Repair By Hernia Sac Disconnection And Peritoneal Closure.

Objectives: To evaluate the short-term outcome of the needlescopic hernia sac disconnection and peritoneal closure in the treatment of primary paediatric inguinal hernia. Method: The prospective study was conducted from April 2019 to April 2021 at the Paediatric Surgery Unit of the General Surgery Department at Kafrelsheikh University Hospital, Egypt, and comprised patients aged 6-144 months having uncomplicated paediatric inguinal hernia. The patients were subjected to needlescopic hernia sac disconnection and peritoneal closure. The follow-up protocol included outpatient visits at 1 week and at 1, 3 and 6 months postoperatively to check for recurrence and other complications. Data was analysed using SPSS 24. RESULTS: Of the 50 patients with 65 hernias, 37(74%) were males and 13(26%) were females. The overall mean age was 50.78± 31.74 months (range: 9-120 months) and mean internal ring diameter was 11.90±3.518mm (range: 8-20mm). The mean operative time was 20.66±2.94 minutesfor unilateral cases and 30.60±5.15 minutesfor bilateral cases. There was no conversion to conventional laparoscopy or to open herniotomy. All cases were followed up for a mean of 11.56± 3.99 months. No recurrence was encountered in any case and the scars were invisible in 40(80%) cases 6 months postoperatively. CONCLUSIONS: Needlescopic hernia sac disconnection and peritoneal closure wasfound to be feasible,safe and effective in the treatment of primary paediatric inguinal hernia.

Analysis and management of pathogens isolated from patients with complicated facial lacerations and abrasions.

Plastic surgeons commonly encounter patients with facial lacerations and/or abrasions in the emergency room. If they are properly treated, facial wounds generally heal well without complications. However, infection can sometimes cause delayed wound healing. We performed wound culture for the early detection of infection and to promote the healing of infected facial wounds. We included 5033 patients with facial wounds who visited the emergency room of Kangnam Sacred Heart Hospital between January 2018 and February 2021. Among them, 104 patients underwent wound culture. We analysed the pathogens isolated and the patients' age, sex, wound site, mechanism of injury, wound healing time, time from injury to culture, time to culture results, and dressing methods used. Pathogens were isolated in slightly less than half of the patients (38.46%); among them, Staphylococcus epidermidis was the most common (47.5%). Methicillin-resistant coagulase-negative staphylococci were isolated in six (15%) patients. Patients with complicated wounds had a longer mean wound healing time (10.83 ± 5.91 days) than those with non-complicated wounds (6.06 ± 1.68 days). Wound culture of complicated facial wounds resulted in the isolation of various types of pathogens, including antibiotic-resistant bacteria and fungi. We recommend the use of wound culture for early detection of infection to prevent delayed wound healing.

Development and validation of a risk assessment scale for pathological scarring.

To develop a risk assessment scale for pathological scarring and validate its psychometric properties. This was a methodological study. Researchers developed the scale based on a literature review, qualitative study and Delphi expert consultation. Subsequently, 409 patients participated in the study to test the psychometric properties of the scale. We evaluated construct validity, content validity, internal consistency reliability, and interrater reliability. The researchers developed a scale consisting of three dimensions and 12 items. Factor analysis extracted a total of four common factors that accounted for 62.22% of the total variance. The results revealed that the item-content validity index (I-CVI) ranged from 0.67 to 1, while the scale-content validity index (S-CVI) was 0.82. Internal consistency reliability: Cronbach's α of the items ranged from 0.67 to 0.76, while Cronbach's α of the whole scale was 0.74. Interrater reliability: the Kappa number was 0.73. The final scale showed adequate construct validity, content validity, and reliability. It is appropriate for use in research and clinical practice settings to identify patients with a risk of pathological scarring. Further study is needed to confirm the scale's validity and reliability in other settings and populations.

Change of the residual myometrial thickness during pregnancy in women who underwent laparoscopic niche resection compared with controls without niche surgery: a prospective comparative cohort study.

BACKGROUND: Reduced residual myometrial thickness before and during pregnancy is associated with uterine rupture or dehiscence after vaginal birth after cesarean delivery. Laparoscopic niche resection performed in case of gynecologic symptoms has shown to increase residual myometrial thickness 6 months after surgery. OBJECTIVE: This study aimed to evaluate the change in residual myometrial thickness from baseline value before pregnancy to the third trimester of pregnancy in women with and without laparoscopic niche resection and evaluate niche presence, niche size during pregnancy vs before pregnancy, and obstetrical outcomes, including uterine rupture and dehiscence in both study groups. STUDY DESIGN: This was a prospective cohort study conducted in an academic medical center. Of note, 2 groups of pregnant women with a previously diagnosed niche were included: (1) women with a large symptomatic niche (residual myometrial thickness of <3 mm) followed by laparoscopic niche resection (LNR group) and (2) women with a niche without niche resection because of minimal symptoms or a residual myometrial thickness of ≥3 mm diagnosed before current pregnancy (expectant group). Participants underwent a transvaginal ultrasound at 12, 20, and 30 weeks of gestation. Changes in residual myometrial thickness and changes in niche measurements over time were analyzed with linear mixed models. RESULTS: A total of 100 women were included, 61 in the LNR group and 39 in the expectant group. The change in residual myometrial thickness from baseline value before niche resection to the third trimester of pregnancy was +2.0 mm in the LNR group vs -1.6 mm in the expectant group (P<.001). Residual myometrial thickness decreased from the first trimester of pregnancy onward in both groups. Although residual myometrial thickness was thinner at baseline in the LNR group, it was thicker in the LNR group than in the expectant group during all trimesters: 3.2 mm (P<.001) in the first trimester of pregnancy, 2.5 mm (P<.001) in the second trimester of pregnancy, and 1.8 mm (P=.001) in the third trimester of pregnancy. Uterine dehiscence was reported in 1 of 50 women (2%) in the LNR group and 7 of 36 women (19%) in the expectant group (P=.007) and was related to the depth of niche-to-residual myometrial thickness ratio before pregnancy (after niche resection) and residual myometrial thickness in the second trimester of pregnancy. No uterine rupture was reported. Most patients received a scheduled cesarean delivery in both groups. There was more blood loss during subsequent cesarean delivery in the LNR group than in the expectant group. CONCLUSION: Here, laparoscopic niche resection resulted in an increased residual myometrial thickness during a subsequent pregnancy. Moreover, a lower number of dehiscence was found in the LNR group than in the expectant group without niche surgery. Per-section blood loss was higher in the LNR group than in the expectant group. In general, laparoscopic niche resection is performed to improve gynecologic symptoms. Currently, there is no evidence to support a laparoscopic niche resection to improve obstetrical outcomes, but the trend toward more uterine dehiscence encourages further research.

Definition and sonographic reporting system for Cesarean scar pregnancy in early gestation: modified Delphi method.

OBJECTIVE: To develop a standardized sonographic evaluation and reporting system for Cesarean scar pregnancy (CSP) in the first trimester, for use by both general gynecology and expert clinics. METHODS: A modified Delphi procedure was carried out, in which 28 international experts in obstetric and gynecological ultrasonography were invited to participate. Extensive experience in the use of ultrasound to evaluate Cesarean section (CS) scars in early pregnancy and/or publications concerning CSP or niche evaluation was required to participate. Relevant items for the detection and evaluation of CSP were determined based on the results of a literature search. Consensus was predefined as a level of agreement of at least 70% for each item, and a minimum of three Delphi rounds were planned (two online questionnaires and one group meeting). RESULTS: Sixteen experts participated in the Delphi study and four Delphi rounds were performed. In total, 58 items were determined to be relevant. We differentiated between basic measurements to be performed in general practice and advanced measurements for expert centers or for research purposes. The panel also formulated advice on indications for referral to an expert clinic. Consensus was reached for all 58 items on the definition, terminology, relevant items for evaluation and reporting of CSP. It was recommended that the first CS scar evaluation to determine the location of the pregnancy should be performed at 6-7 weeks' gestation using transvaginal ultrasound. The use of magnetic resonance imaging was not considered to add value in the diagnosis of CSP. A CSP was defined as a pregnancy with implantation in, or in close contact with, the niche. The experts agreed that a CSP can occur only when a niche is present and not in relation to a healed CS scar. Relevant sonographic items to record included gestational sac (GS) size, vascularity, location in relation to the uterine vessels, thickness of the residual myometrium and location of the pregnancy in relation to the uterine cavity and serosa. According to its location, a CSP can be classified as: (1) CSP in which the largest part of the GS protrudes towards the uterine cavity; (2) CSP in which the largest part of the GS is embedded in the myometrium but does not cross the serosal contour; and (3) CSP in which the GS is partially located beyond the outer contour of the cervix or uterus. The type of CSP may change with advancing gestation. Future studies are needed to validate this reporting system and the value of the different CSP types. CONCLUSION: Consensus was achieved among experts regarding the sonographic evaluation and reporting of CSP in the first trimester. © 2021 The Authors.

Epidemiologic features and risk of scarring in pediatric patients with kerion celsi.

BACKGROUND: Kerion celsi represents the inflammatory extreme of tinea capitis, as a delayed hypersensitivity reaction to the causative dermatophyte. Data regarding prevalence, trends in pathogens, and risk factors for scarring are limited. OBJECTIVE: The main objective of the study is to assess clinical and epidemiologic features of children with kerion celsi and risk factors for scarring. METHODS: We reviewed medical records of pediatric patients with kerion celsi treated between January 2006 and July 2020. RESULTS: Among 80 patients, the prevalence of permanent alopecia was 27.5%. Patients with remaining alopecia presented to our clinic at a mean 1.3 months earlier than those with complete response to treatment (2.2 ± 2.1 and 3.4 ± 4.8, respectively; p < .05). Patients of Ethiopian ethnicity were more represented than in the general population; however, scarring was observed in only 11% (p = 0.08). Outcomes did not differ by pathogen, antifungal treatment prescribed, duration of treatment, or the use of prednisone or antibiotics. CONCLUSIONS: Scarring alopecia is a common complication of kerion celsi. Host innate immune response, pathogen virulence, and treatment timeline should be considered as possible variables affecting risk of scarring in the future studies.

[Atypical keloids with an unusual myofibroblastic differentiation in a patient with acne vulgaris]. / Atypische, Myofibroblasten-reiche Keloide im Rahmen einer Acne vulgaris.

We present the case of a patient with a discreet acne and multiple keloids in the area of the upper trunk, histologically showing an unusual myofibroblastic differentiation. So far, the clinical course shows a poor response to the treatment, including cryotherapy, intralesional corticosteroid injections, occlusive silicone dressings and dye laser.

Is massage an effective intervention in the management of post-operative scarring? A scoping review.

BACKGROUND: Scar massage is a widely used treatment modality in hand therapy. This intervention is thoroughly discussed in the literature relating to burns rehabilitation, however, the evidence for its use in treating linear scars following surgery is limited. PURPOSE OF STUDY: To collate the empirical literature on scar massage for the treatment of postsurgical cutaneous scars. STUDY DESIGN: Scoping review. METHODS: Medline, EMBASE, CINAHL, AMED, Scopus, ProQuest Dissertations & Theses Global, and the Joanna Briggs Institute were searched from inception to December 2020. Two researchers used a data extraction tool to record key demographic, intervention and outcome data, and to apply the Oxford Levels of Evidence for each study. RESULTS: Twenty-five studies met the inclusion criteria, reporting on a combined sample of 1515 participants. Only two papers addressed hand or wrist scars (92 participants). While all studies reported favorable outcomes for scar massage, there were 45 different outcome measures used and a propensity towards non-standardized assessment. Intervention protocols varied from a single session to three treatments daily for 6 months. The results from 13 studies were confounded by the implementation of additional rehabilitation interventions. CONCLUSIONS: The overall findings suggest that while there may be benefits to scar massage in reducing pain, increasing movement and improving scar characteristics; there is a lack of consistent research methods, intervention protocols and outcome measures. This scoping review highlights the heterogenous nature of research into scar massage following surgery and supports the need for further research to substantiate its use in the clinical setting.

A new technique of suturing using adhesive skin closure for uncooperative patients.

Open wounds are usually closed with suture. However, young patients often do not cooperate and prevent proper suture placement. Young patients are often terrified of mild pain and wholly uncooperative, which is why we introduce this timesaving, less painful, more aesthetic technique of placing and removing stitches. 104 patients with facial lacerations aged 5 to 15 years were treated at a single center from May 2019 to March 2021. Patients were randomly assigned equally to a simple interrupted suture group (the SI group) or a continuous locking with Steri-Strip group (the CS group). Suture times, times for stitch removal, pain scores at stitch removal and mature scar scores were evaluated. Suture and stitch removal times were significantly shorter, and pain scores at stitch removal and observer scar assessment scale scores were lower in the CS group. Patient scar assessment scale score was non-significantly lower in the SI group. This study shows that the novel continuous locking with the Steri-Strip technique is easier and quicker to perform, causes less pain when removing stitches, provides better aesthetic results than the simple interrupted suture technique and suggests the continuous locking with Steri-Strip technique would be very useful for uncooperative young patients.

Cross-cultural adaptation into French and validation of the SCAR-Q questionnaire.

PURPOSE: Most questionnaires designed to evaluate patient-reported outcomes regarding scarring are available in English. The objective was to generate a validated French version of the SCAR-Q questionnaire. METHODS: The SCAR-Q questionnaire (including Appearance, Symptom and Psychological impact scales) was translated into French using a translation-back-translation process in accordance with international guidelines (ISPOR and WHO). For validation, two hundred patients consulting in our tertiary center completed the questionnaire. We tested scale reliability (Cronbach's α), floor/ceiling effects and item redundancy (inter-item correlations). Structural validity was tested using confirmatory factor analysis (CFA) with the robust weighted least squares (WLSMV) estimator and Delta parameterization. Model fit was examined using the root mean square error of approximation (RMSEA), the comparative fit index (CFI) and the Tucker-Lewis index (TLI). Correlations between scales and scale repeatability were tested (Spearman coefficient, Intra-class-coefficient). RESULTS: Four steps were required to obtain a translation consistent with the original version. Two hundred patients completed the questionnaire for validation. Internal consistency analysis found Cronbach's alphas > 0.7 for all scales (0.90 < α < 0.97). No floor or ceiling effect was found for all items (max = 85%). A ceiling effect was observed for all scales. Appearance and psychosocial impact scale items showed redundancy, with many inter-item correlations above 0.7. The CFA of the original structure displayed a reasonable fit, with RMSEA = 0.065, CFI = 0.974 and TLI = 0.972. Scales were positively correlated (0.45 < ρ < 0.65; p < 0.001). Test-retest intra-class correlation coefficients ranged from 0.94 to 0.99 for all scales. CONCLUSION: A French version of the SCAR-Q questionnaire is validated, ready for use.
