    The patient and observer scar assessment scale (POSAS) recently emerged as a promising method, reflecting both observer's and patient's opinions in evaluating scar. This tool was shown to be consistent and reliable in burn scar assessment, but it has not been tested in the setting of skin graft scar in skin cancer patients. To evaluate facial skin graft scar applied to POSAS and to compare with objective scar assessment tools. Twenty three patients, who diagnosed with facial cutaneous malignancy and transplanted skin after Mohs micrographic surgery, were recruited. Observer assessment was performed by three independent rates using the observer component of the POSAS and Vancouver scar scale (VSS). Patient self-assessment was performed using the patient component of the POSAS. To quantify scar color and scar thickness more objectively, spectrophotometer and ultrasonography was applied. Inter-observer reliability was substantial with both VSS and the observer component of the POSAS (average measure intraclass coefficient correlation, 0.76 and 0.80, respectively). The observer component consistently showed significant correlations with patients' ratings for the parameters of the POSAS (all p -valuesskin graft scar assessment in skin cancer patients, the POSAS showed acceptable inter-observer reliability. This tool was more comprehensive and had higher correlation with patient's opinion.

    Several scar-scoring scales exist to clinically monitor burn scar development and maturation. Although scoring scars through direct clinical examination is ideal, scars must sometimes be scored from photographs. No scar scale currently exists for the latter purpose. We modified a previously described scar scale (Yeong et al., J Burn Care Rehabil 1997) and tested the reliability of this new scale in assessing burn scars from photographs. The new scale consisted of three parameters as follows: scar height, surface appearance, and color mismatch. Each parameter was assigned a score of 1 (best) to 4 (worst), generating a total score of 3-12. Five physicians with burns training scored 120 representative photographs using the original and modified scales. Reliability was analyzed using coefficient of agreement, Cronbach alpha, intraclass correlation coefficient, variance, and coefficient of variance. Analysis of variance was performed using the Kruskal-Wallis test. Color mismatch and scar height scores were validated by analyzing actual height and color differences. The intraclass correlation coefficient, the coefficient of agreement, and Cronbach alpha were higher for the modified scale than those of the original scale. The original scale produced more variance than that in the modified scale. Subanalysis demonstrated that, for all categories, the modified scale had greater correlation and reliability than the original scale. The correlation between color mismatch scores and actual color differences was 0.84 and between scar height scores and actual height was 0.81. The modified scar scale is a simple, reliable, and useful scale for evaluating photographs of burn patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    In this study, we examined the plausibility of the mediating effect of the levels of patient scar assessment on the relationship between burn severity measured with total body surface area and burn-specific health-related quality of life (HRQL) among patients with burns in South Korea. In this cross sectional descriptive study, we collected data from 100 burn patients in three burn centers specializing in burn care in South Korea. Patient scar assessment, burn specific HRQL, and burn-related characteristics were self-reported with anonymous, paper-based surveys. The findings showed a positive correlation between burn severity, patient scar assessment, and HRQL in burn patients. The evidence of this paper is that quality of life after burns more determined by scar characteristics than burn severity. In the light of the poor HRQL in burn patients, the results of this study support that improving scar status could improve patients' HRQL. Health care providers should keep in mind that patients' perspectives of their scars would be a great indicator of their HRQL, so the providers' focus should be on intensive scar management intervention in their care.

    This study describes the ultrasound assessment of burn scars in paediatric patients and the association of these scar thickness with laser Doppler imaging (LDI) determined burn depth. A total of 60 ultrasound scar assessments were conducted on 33 scars from 21 paediatric burn patients at 3, 6 and 9 months after-burn. The mean of peak scar thickness was 0.39±0.032 cm, with the thickest at 6 months (0.40±0.036 cm). There were 17 scald burn scars (0.34±0.045 cm), 4 contact burn scars (0.61±0.092 cm), and 10 flame burn scars (0.42±0.058 cm). Each group of scars followed normal distributions. Twenty-three scars had original burns successfully scanned by LDI and various depths of burns were presented by different colours according to blood perfusion units (PU), with dark blue burns, with the thinnest scars for green coloured burns and the thickest for dark blue coloured burns. Within light blue burns, grafted burns healed with significantly thinner scars than non-grafted burns. This study indicates that LDI can be used for predicting the risk of hypertrophic scarring and for guiding burn care. To our knowledge, this is the first study to correlate the thickness of burns scars by ultrasound scan with burn depth determined by LDI. Copyright © 2010 Elsevier Ltd and ISBI. All rights reserved.

    This study assessed patient-perceived levels of scar assessment and burn-specific quality of life (QOL) in Korean burn patients admitted to burn care centers and identified differences in scar assessment and QOL based on various patient characteristics. A cross-sectional descriptive study using anonymous paper-based survey methods was conducted with 100 burn patients from three burn centers specializing in burn care in South Korea. Mean subject age was 44.5 years old, and 69% of the subjects were men. The overall mean QOL was 2.91 out of 5. QOL was lowest for the work subdomain (2.25±1.45) followed by the treatment regimen subdomain (2.32±1.16). The subjects' mean total scar assessment score was 35.51 out of 60, and subjects were most unsatisfied with scar color. Subjects with low income, flame-source burns, severe burns, visible scars, and scars on face or hand reported significantly lower QOL. Subjects with severe burn degree and burn range perceived their burn scar condition to be worse than that of others. The results show that burn subjects experience the most difficulties with their work and the treatment regimen. Subjects with severe burn and visible scarring have a reduced QOL and a poor scar status. Scar management intervention may improve QOL of burn patients especially those with severe burn and visible scars. Further studies are warranted to evaluate the relationship between scar assessment and QOL. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available STUDY BACKGROUND Post acne scars are always a challenge to treat, especially the ones which are deep seated. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but with considerable morbidity and interference with the daily activities of the patient in the post-treatment period. Microneedling or dermaroller therapy is one of the new treatment options in the management of acne scars with satisfactory improvement and no significant side effect. The aim of the present study is to perform an objective evaluation the efficacy of microneedling in the treatment of atrophic acne scars. MATERIALS AND METHODS Thirty patients of skin type III-V having atrophic facial acne scars presenting to our dermatology OPD. were received multiple sittings of microneedling (dermaroller treatment with an interval of 6 weeks between each session. Goodman & Baron’s acne scar grading system was used for assessment of their scars and was evaluated clinically by serial photography at the start as well as at two months after the conclusion of the treatment. Patients on anticoagulant therapy, of keloidal tendency, with bleeding disorders, vitiligo patients, pregnant and lactating mothers and patients with active acne lesions were excluded from the study. The duration of this study was for ten months-from January 2014 to October 2014. RESULTS Any change in the grading of scars after the end of treatment and follow-up period was noted down. The efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s Global Acne Scarring System. Out of 30 patients, 26(80.64% patients achieved a reduction in the severity of their scarring by one or two grades. Quantitative assessment showed that 13.3% of patients had minimal, 16.6% had good and 70% showed very good improvement. Adverse effects were limited to transient pain, erythema and edema. CONCLUSION Microneedling therapy seems to be

    Post-acne atrophic scarring is a major concern for which standardized outcome measures are needed. Traditionally, this type of scar has been classified based on shape; but survey of practicing dermatologists has shown that atrophic scar morphology has not been well enough defined to allow good agreement in clinical classification. Reliance on clinical assessment is still needed at the current time, since objective tools are not yet available in routine practice. Evaluate classification for atrophic acne scars by shape, size, and facial location and establish reliability in assessments. We conducted a non-interventional study with dermatologists performing live clinical assessments of atrophic acne scars. To objectively compare identification of lesions, individual lesions were marked on a high-resolution photo of the patient that was displayed on a computer during the clinical evaluation. The Jacob clinical classification system was used to define three primary shapes of scars 1) icepick, 2) boxcar, and 3) rolling. To determine agreement for classification by size, independent technicians assessed the investigators' markings on digital images. Identical localization of scars was denoted if the maximal distance between their centers was ≤ 60 pixels (approximately 3 mm). Raters assessed scars on the same patients twice (morning/afternoon). Aggregate models of rater assessments were created and analyzed for agreement. Raters counted a mean scar count per subject ranging from 15.75 to 40.25 scars. Approximately 50% of scars were identified by all raters and ~75% of scars were identified by at least 2 of 3 raters (weak agreement, Kappa pairwise agreement 0.30). Agreement between consecutive counts was moderate, with Kappa index ranging from 0.26 to 0.47 (after exclusion of one outlier investigator who had significantly higher counts than all others). Shape classifications of icepick, boxcar, and rolling differed significantly between raters and even for same raters at

    Late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) imaging is the gold standard for myocardial scar evaluation. Heterogeneous areas of scar ('gray zone'), may serve as arrhythmogenic substrate. Various gray zone protocols have been correlated to clinical outcomes and ventricular tachycardia channels. This study assessed the quantitative differences in gray zone and scar core sizes as defined by previously validated signal intensity (SI) threshold algorithms. High quality LGE-CMR images performed in 41 cardiomyopathy patients [ischemic (33) or non-ischemic (8)] were analyzed using previously validated SI threshold methods [Full Width at Half Maximum (FWHM), n-standard deviation (NSD) and modified-FWHM]. Myocardial scar was defined as scar core and gray zone using SI thresholds based on these methods. Scar core, gray zone and total scar sizes were then computed and compared among these models. The median gray zone mass was 2-3 times larger with FWHM (15 g, IQR: 8-26 g) compared to NSD or modified-FWHM (5 g, IQR: 3-9 g; and 8 g. IQR: 6-12 g respectively, p zone extent (percentage of total scar that was gray zone) also varied significantly among the three methods, 51 % (IQR: 42-61 %), 17 % (IQR: 11-21 %) versus 38 % (IQR: 33-43 %) for FWHM, NSD and modified-FWHM respectively (p zone and scar core. Infarct core and total myocardial scar mass also differ using these methods. Further evaluation of the most accurate quantification method is needed.

    Objective: To assess the value of free-breathing 3D phase sensitive inversion recovery (PSIR) turbo FLASH for demonstrating the left ventricular myocardial scar in patients with myocardial infarction. Methods: Twenty-three patients with myocardial infarction underwent 2D and 3D phase sensitive inversion recovery (PSIR) Turbo FLASH sequences 10-15 minutes after injection of dimeglumine gadopentetate. The image quality, the area, location and volume of hyperenhanced scar were independently assessed by two experienced radiologists. Student's t test or rank sum test and Pearson linear correlation were used for the statistics. Results: There were no significant differences in the overall image quality (2.57± 0.59 vs 2.39±0.66, Z=-0.93, P=0.35), the area (24.48±10.83 vs 29.00±11.56, Z=-1.41, P=0.16) and location (16.78±6.51 vs 18.87±6.76, Z=-1.17, P=0.24) of hyperenhanced scar between 2D and 3D PSIR sequences. The mean volume of hyperenhanced scar was significantly greater in 3D PSIR sequence than that in 2D PSIR sequence [(23.46±10.61) vs (31.65±13.86) cm 3 , t=-2.25, P= 0.03]. There was a good correlation in the volume of hyperenhanced scar between 2D PSIR and 3D PSIR sequences (r=0.940, P 2 =0.883). Conclusion: Free-breathing 3D PSIR Turbo FLASH is a promising new imaging technique for accurate assessment of myocardial scar. (authors)

    Scar homogenization improves long-term ventricular arrhythmia-free survival compared with standard limited-substrate ablation in patients with post-infarction ventricular tachycardia (VT). Whether such benefit extends to patients with nonischemic cardiomyopathy and scar-related VT is unclear. The aim of this study was to assess the long-term efficacy of an endoepicardial scar homogenization approach compared with standard ablation in this population. Consecutive patients with dilated nonischemic cardiomyopathy (n = 93), scar-related VTs, and evidence of low-voltage regions on the basis of pre-defined criteria on electroanatomic mapping (i.e., bipolar voltage homogenization and standard ablation, respectively (p = 0.01). During a mean follow-up period of 14 ± 2 months, single-procedure success rates were 63.9% after scar homogenization and 38.6% after standard ablation (p = 0.031). After multivariate analysis, scar homogenization and left ventricular ejection fraction were predictors of long-term success. During follow-up, the rehospitalization rate was significantly lower in the scar homogenization group (p = 0.035). In patients with dilated nonischemic cardiomyopathy, scar-related VT, and evidence of low-voltage regions on electroanatomic mapping, endoepicardial homogenization of the scar significantly increased freedom from any recurrent ventricular arrhythmia compared with a standard limited-substrate ablation. However, the success rate with this approach appeared to be lower than previously reported with ischemic cardiomyopathy, presumably because of the septal and midmyocardial distribution of the scar in some patients.

    Introduction: Purpose of our study is to evaluate the role of the apparent diffusion coefficient (ADC) in the diagnosis of recurrent tumor on the scar in patients operated for breast cancer. Assess, therefore, the weight of diagnostic diffusion echo-planar sequence, in association with the morphological and dynamic sequences in the diagnosis of tumor recurrence versus surgical scar. Materials and methods: From September 2007 to March 2009, 72 patients operated for breast cancer with suspected recurrence on the scar were consecutively subjected to magnetic resonance imaging (MRI), including use of a diffusion sequence. All patients with pathological enhancement in the scar were then subjected to histological typing. MRI was considered negative in the absence of areas of suspicious enhancement. In all cases it was measured the ADC value in the scar area or in the area with pathological enhancement. The ADC values were compared with MRI findings and histological results obtained. Results: 26 cases were positive/doubtful at MRI and then subjected to histological typing: of these recurrences were 20 and benign were 6. 46 cases were judged negative at MRI and therefore not sent to cyto-histology. The average ADC value of recurrences was statistically lower of scarring (p < 0.001). Conclusions: ADC value can be a specific parameter in differential diagnosis between recurrence and scar. The diffusion sequence, in association with the morphological and dynamic sequences, can be considered a promising tool for the surgical indication in suspected recurrence of breast cancer.

    There is a paucity of studies investigating laser resurfacing in Fitzpatrick skin phototypes (SPT) IV to VI. To assess the efficacy and safety of fractional nonablative laser resurfacing in the treatment of acne scarring in patients with SPT IV to VI. The authors conducted a randomized, investigator-blinded and rater-blinded, split-face comparative study of adults with SPT IV to VI and facial acne scars treated with 2 different density settings and the same fluence. Quantitative global scarring grading system (QGSGS) scores were significantly improved from baseline at 16 and 24 weeks (p = .0277). Improvements in QGSGS scores after higher and lower density treatments were statistically similar (p = .96). The live-blinded dermatologist, the blinded dermatologist photoraters, and the patients rated scars as being significantly more improved by visual analog scale at weeks 16 and 24 compared with baseline (p skin types IV to VI. Self-limited postinflammatory hyperpigmentation was a common occurrence, especially with higher treatment densities.

    The current study aimed to assess the value of microplasma radiofrequency technology combined with triamcinolone for the therapy of Chinese patients with hypertrophic scar. A total of 120 participants with hypertrophic scars were enrolled in the current study. Participants were divided into two groups based on sex, and then randomly and evenly divided into four groups (Groups A, B, C, and D). Participants in Group A received microplasma radiofrequency technology combined with triamcinolone. Participants in Group B received microplasma radiofrequency technology combined with normal saline. Participants in Groups C and D received triamcinolone (40 and 10 mg/mL) injected directly into scar. Experienced physicians evaluated the condition of scars according to the Vancouver Scar Scale 1 month before and after the therapy. There was no difference in age, sex, area, height and location of scars, and Vancouver Scar Scale scores before the therapy between any groups (P>0.05 for all). Vancouver Scar Scale scores after the therapy were significantly lower than those before the therapy in all groups (P0.05 for all). Incidences of tissue atrophy after the therapy were significantly lower in Groups A and B than in Group C (P0.05 for all). Microplasma radiofrequency technology combined with triamcinolone improved the therapeutic effect on Chinese patients with hypertrophic scar and reduced the risk of tissue atrophy compared with the use of either microplasma radiofrequency technology or triamcinolone injection alone.

    Full Text Available Background: Hypertrophic scar causes physical and psychological problems. Thus understanding the factors related to the occurrence of hypertrophic scar tissue is needed. Little is known about its influencing factors in Indonesia, especially in Garut. Objective: This study aims to examine the relationships between hypertrophic scar and its influencing factors, and identify the most dominant factor of the occurrence of hypertrophic scars. Methods: This was an observational case control study using retrospective approach in Polyclinic of Surgery of Regional Public Hospital of dr. Slamet of Garut Regency. There were 40 samples recruited in this study by purposive sampling, which was divided to be case group (20 patients and control group (20 patients. Data were collected using Stony Brook Scar Evaluation Scale by observation and documentation of the medical records of patients. Data were analyzed using logistic regression analysis Results: Findings indicated that there were significant relationships between the surgical wound infection (p = 0.02, family history (p = 0.026, and type of suture (p = 0.043 with the occurrence of hypertrophic scars. The most dominant factor on the occurrence of hypertrophic scars was type of suture, acid polyglactin 910. The variables that had no significant relationships with the occurrence of hypertrophic scar tissue were age (p = 0.34, area of surgical wound (p = 0.177, and smoking habit (p = 0.479. Conclusion: There were significant relationships between infection of surgical wound, genetic history, the type of suture, and the occurrence of hypertrophic scar tissue. The most dominant factor that influenced the occurrence of hypertrophic scar tissue was the type of suture. Therefore, it is suggested to health professionals to modify the using of acid polyglactin 910 sutures, and nurses particularly need to provide the information regarding the family history and genetic-related hypertrophic scar, and prevent the

    Many surgeons recommend postoperative scar massage to improve aesthetic outcome, although scar massage regimens vary greatly. To review the regimens and efficacy of scar massage. PubMed was searched using the following key words: "massage" in combination with "scar," or "linear," "hypertrophic," "keloid," "diasta*," "atrophic." Information on study type, scar type, number of patients, scar location, time to onset of massage therapy, treatment protocol, treatment duration, outcomes measured, and response to treatment was tabulated. Ten publications including 144 patients who received scar massage were examined in this review. Time to treatment onset ranged from after suture removal to longer than 2 years. Treatment protocols ranged from 10 minutes twice daily to 30 minutes twice weekly. Treatment duration varied from one treatment to 6 months. Overall, 65 patients (45.7%) experienced clinical improvement based on Patient Observer Scar Assessment Scale score, Vancouver Scar Scale score, range of motion, pruritus, pain, mood, depression, or anxiety. Of 30 surgical scars treated with massage, 27 (90%) had improved appearance or Patient Observer Scar Assessment Scale score. The evidence for the use of scar massage is weak, regimens used are varied, and outcomes measured are neither standardized nor reliably objective, although its efficacy appears to be greater in postsurgical scars than traumatic or postburn scars. Although scar massage is anecdotally effective, there is scarce scientific data in the literature to support it. © 2011 by the American Society for Dermatologic Surgery, Inc.

    Existing studies suggest that exercise-induced ischemia produces an increase in left ventricular end-diastolic volume; however, all of these studies have included patients with previous myocardial infarction. To test whether the end-diastolic volume response to exercise is related to the extent of myocardial scar, the results of gated radionuclide supine exercise tests performed on 130 subjects were reviewed. The patient group comprised 130 subjects were reviewed. The patient group comprised 130 men aged 35 to 65 years (mean +/- SD 52 +/- 5) with documented coronary heart disease. The extent of myocardial ischemia and scar formation was assessed by stress electrocardiography and thallium-201 scintigraphy. Patients were classified into three groups on the basis of left ventricular end-diastolic volume response at peak exercise: group 1 (n = 72) had an increase of end-diastolic volume greater than 10%, group 2 (n = 41) had a change in end-diastolic volume less than 10% and group 3 (n = 17) had a decrease in end-diastolic volume greater than 10% (n = 17). At rest there was no significant difference among groups in heart rate, systolic blood pressure, end-diastolic (EDVrest) or end-systolic volumes or ejection fraction (p greater than 0.05); however, at peak exercise the end-systolic volume response was significantly greater for group 1 (p less than 0.002)

    The authors report the results of an analysis of recurrences in postoperative scar in patients with breast cancer for evaluation of the effectiveness of postoperative radiotherapy. In a group of 423 cases recurrences in scar were observed in 51 (12.1%). In the group of patients who had been given postoperative radiotherapy to the scar the frequency of recurrences was lower (8.1%) as compared with the group treated only surgically (16.5%), in the group treated by preoperative radiotherapy it was high (17.1%) and in the group with postoperative radiotherapy given only to regional lymph nodes it was even higher (18.0%). The results of analysis indicate the effectiveness of postoperative radiotherapy to the scar.

    Full Text Available Background. Onion extracts have been shown in vitro to accelerate wound healing. Results from clinical studies on surgical scars in Caucasians were disappointing. The aim of this study is to evaluate the effectiveness of onion extract gel in improving the cosmetic and symptoms of surgical scars in Asians. Patients/Methods. Twenty Asians who had new Pfannenstiel’s cesarean section scars were recruited in this prospective double-blinded, split-scar study. Each side was randomly assigned treatment with onion extract gel or placebo at 7 days after surgery. The product was applied three times daily for 12 weeks. Subjects were evaluated at baseline and 4th and 12th weeks. Scar redness was assessed by calorimeter, scar height and pliability were assessed by blinded investigators, and scar symptoms and overall cosmetic improvement were assessed by subjects. Results. Sixteen subjects completed the study. A statistically significant difference between two sides of scar in terms of scar height and scar symptoms was found. There was no statistically significant difference in scar redness, scar pliability, and overall cosmetic appearance between two sides. Conclusions. The early use of topical 12% onion extract gel on Pfannenstiel’s cesarean section scar in Asians resulted in the improvement of scar height and scar symptoms.

    To realize objective atrial scar assessment, this study aimed to develop a fully automatic method to segment the left atrium (LA) and pulmonary veins (PV) from late gadolinium-enhanced (LGE) magnetic resonance imaging (MRI). The extent and distribution of atrial scar, visualized by LGE-MRI, provides important information for clinical treatment of atrial fibrillation (AF) patients. Forty-six AF patients (age 62 ± 8, 14 female) who underwent cardiac MRI prior to RF ablation were included. A contrast-enhanced MR angiography (MRA) sequence was acquired for anatomy assessment followed by an LGE sequence for LA scar assessment. A fully automatic segmentation method was proposed consisting of two stages: 1) global segmentation by multiatlas registration; and 2) local refinement by 3D level-set. These automatic segmentation results were compared with manual segmentation. The LA and PVs were automatically segmented in all subjects. Compared with manual segmentation, the method yielded a surface-to-surface distance of 1.49 ± 0.65 mm in the LA region when using both MRA and LGE, and 1.80 ± 0.93 mm when using LGE alone (P automatic and manual segmentation was comparable to the interobserver difference (P = 0.8 in LA region and P = 0.7 in PV region). We developed a fully automatic method for LA and PV segmentation from LGE-MRI, with comparable performance to a human observer. Inclusion of an MRA sequence further improves the segmentation accuracy. The method leads to automatic generation of a patient-specific model, and potentially enables objective atrial scar assessment for AF patients. J. Magn. Reson.

    The purpose of this study was to assess the role of fluorine 18 ((18)F)-fluorodeoxyglucose positron emission tomography-computed tomography ((18)F-FDG PET-CT) in evaluating various parameters in patients with surgical scar site recurrence in cervical carcinoma. Data of all patients with cervical cancer (n = 329) who underwent PET-CT at our institute between 2005 and 2013 was reviewed. Of these 329 patients, 132 patients who were surgically treated and underwent restaging/follow-up PET-CT were included in the present study for final analysis. Tumor recurrence at the abdominal surgical scar site was looked for. Abnormal uptakes suggestive of active disease at other sites were also noted. Maximum standardized uptake value was measured for all the lesions. Patients with scar site recurrence were taken as cases (n = 6), whereas the remaining patients served as controls (n = 126). Comparison with conventional imaging modalities was made wherever available. Histopathological examination was always sought for. The incidence of scar site recurrence after surgery was found to be 4.5% (6/117). A total of 56 of 132 patients had recurrent disease, including 6 patients with scar site recurrence. All of the patients with scar site recurrence also had recurrent disease at other sites (local, nodal, or distant). Conventional imaging modalities were available in 4 of these 6 patients and detected scar site recurrence in 3 of those 4 patients. In patients with scar site recurrence, the mean ± SD time to scar site recurrence was 14.0 ± 10.9 months (median, 10 months; range, 7-36 months). Significant difference was seen between cases and control for International Federation of Genecology and Oncology stage (P = 0.001) and nodal recurrence (P = 0.007). Additionally, age, nodal recurrence, distant recurrence, and scar site recurrence were significantly associated with death. Scar site recurrence carries a poor prognosis, and the incidence is much higher than previously known when PET

    Long-term outcome of burn scars as well as the relation with clinically relevant parameters has not been studied quantitatively. Therefore, we conducted a detailed analysis on the clinical changes of burn scars in a longitudinal setup. In addition, we focused on the differences in scar quality in relation to the depth, etiology of the burn wound and age of the patient. Burn scars of 474 patients were subjected to a scar assessment protocol 3, 6, and 12 months postburn. Three different age groups were defined (≤5, 5-18, and ≥18 years). The observer part of the patient and observer scar assessment scale revealed a significant (p burned (p  0.230) have no significant influence on scar quality when corrected for sex, total body surface area burned, time, and age or etiology, respectively. © 2012 by the Wound Healing Society.

    Full Text Available Background: Atrophic acne scars are difficult to treat. The demand for less invasive but highly effective treatment for scars is growing. Objective: To assess the efficacy of combination therapy using subcision, microneedling and 15% trichloroacetic acid (TCA peel in the management of atrophic scars. Materials and Methods: Fifty patients with atrophic acne scars were graded using Goodman and Baron Qualitative grading. After subcision, dermaroller and 15% TCA peel were performed alternatively at 2-weeks interval for a total of 6 sessions of each. Grading of acne scar photographs was done pretreatment and 1 month after last procedure. Patients own evaluation of improvement was assessed. Results: Out of 16 patients with Grade 4 scars, 10 (62.5% patients improved to Grade 2 and 6 (37.5% patients improved to Grade 3 scars. Out of 22 patients with Grade 3 scars, 5 (22.7% patients were left with no scars, 2 (9.1% patients improved to Grade 1and 15 (68.2% patients improved to Grade 2. All 11 (100% patients with Grade 2 scars were left with no scars. There was high level of patient satisfaction. Conclusion: This combination has shown good results in treating not only Grade 2 but also severe Grade 4 and 3 scars.

    With rapid advancement in cutaneous laser therapy, Q-switched lasers have become the standard treatment for tattoo removal. The longer wavelength Q-switched Nd:YAG laser is used when removing tattoos in darker skin patients to avoid scarring and permanent pigment changes. Nevertheless, the local experience revealed that nearly 25% of the Chinese patients developed scarring. Meanwhile, multiple clinical studies have shown that Contractubex gel (Merz Pharma, Frankfurt, Germany) was effective in the treatment and prevention of hypertrophic scars and keloids. To evaluate the efficacy of Contractubex gel in the prevention of scarring after laser removal of tattoos in Chinese patients. A total of 120 Chinese patients with 144 professional blue-black tattoos were recruited into the study. They were randomly assigned into the Contractubex group or the control group. All patients were treated with a QS 1,064-nm Nd:YAG laser using a 3-mm spot size, a 10-Hz repeat rate, a pulse duration of 6 nanoseconds, and fluences that ranged from 3.6 to 4.8 J/cm2 (mean fluence, 4.2 J/cm2). The treated areas were assessed 3 months after the last treatments for clinical clearance and complications. Fifty-two patients with 61 tattoos in the Contractubex group were able to achieve a mean clearing rate of 82.3+/-11.6%. There were 7 tattoos in 7 patients that developed scarring, 4 patients had permanent hypopigmentation, and 3 patients had transient hyperpigmentation. In contrast, 55 patients with 68 tattoos in the control group had a mean clearing rate of 80.4+/-11.3%. Among them, 16 tattoos in 14 patients developed scarring, 4 patients had permanent hypopigmentation, and 5 patients had transient hyperpigmentation. Although there was no significant difference in age, sex, fluence, treatment session, and clinical clearance between the two groups, the Contractubex group had a statistically significantly lower rate of scarring than the control group (ptattoos.

    Cesarean scar ectopic pregnancies (CSEPs) are rare but may have serious adverse consequences and are therefore important to promptly recognize on sonography. We aim to describe the typical sonographic appearances. Potential treatments are discussed, including sonographic guidance for transcervical injection of methotrexate (MTX) into the gestational sac. Two patients with CSEPs were treated with systemic and intra-amniotic administration of MTX under sonographic guidance. Both patients were followed clinically after medical treatment, resulting in low maternal morbidity and mortality. Considering the increasing rate of cesarean delivery and the increased risk of CSEPs, sonologists should be familiar with the sonographic appearances of a pregnancy implanted into the cesarean scar. We show how to correctly diagnose scar implantation and describe how to perform sonographically guided transcervical injection of MTX.

    Pressure garment therapy (PGT) is an established treatment for the prevention and treatment of hypertrophic scarring; however, there is limited evidence for its effectiveness. Burn survivors often experience multiple issues many of which are not adequately captured in current PGT trial measures. To assess the effectiveness of PGT it is important to understand what outcomes matter to patients and to consider whether patient-reported outcome measures (PROMs) can be used to ascertain the effect of treatments on patients' health-related quality of life. This study aimed to (a) understand the priorities and perspectives of adult burns patients and the parents of burns patients who have experienced PGT via in-depth qualitative data, and (b) compare these with the concepts captured within burn-specific PROMs. We undertook 40 semi-structured interviews with adults and parents of paediatric and adolescent burns patients who had experienced PGT to explore their priorities and perspectives on scar management. Interviews were audio-recorded, transcribed and thematically analysed. The outcomes interpreted within the interview data were then mapped against the concepts captured within burn-specific PROMs currently in the literature. Eight core outcome domains were identified as important to adult patients and parents: (1) scar characteristics and appearance, (2) movement and function, (3) scar sensation, (4) psychological distress, adjustments and a sense of normality, (5) body image and confidence, (6) engagement in activities, (7) impact on relationships, and (8) treatment burden. The outcome domains presented reflect a complex holistic patient experience of scar management and treatments such as PGT. Some currently available PROMs do capture the concepts described here, although none assess psychological adjustments and attainment of a sense of normality following burn injury. The routine use of PROMs that represent patient experience and their relative contribution to trial

  11. Periauricular Keloids on Face-Lift Scars in a Patient with Facial Nerve Paralysis

    Directory of Open Access Journals (Sweden)

    Masayo Aoki, MD, PhD

    2017-07-01

    Full Text Available Summary:. Keloids are caused by excessive scar formation that leads to scar growth beyond the initial scar boundaries. Keloid formation and progression is promoted by mechanical stress such as skin stretch force. Consequently, keloids rarely occur in paralyzed areas and areas with little skin tension, such as the periauricular region. Therefore, periauricular incision is commonly performed for face lifts. We report a rare case of keloids that arose from face-lift scars in a patient with bilateral facial nerve paralysis. A 51-year-old Japanese man presented with abnormal proliferative skin masses in bilateral periauricular scars. Seventeen years before, he had a cerebral infarction that resulted in permanent bilateral facial nerve paralysis. Three years before presentation, the patient underwent face-lift surgery with periauricular incisions. We diagnosed multiple keloids. We removed the masses surgically, closed the wounds with sutures in the superficial musculoaponeurotic system layer to reduce tension on the wound edges, reconstructed the earlobes with local skin flaps, and provided 2 consecutive days of radiotherapy. The wounds/scars were managed with steroid plasters and injections. Histology confirmed that the lesions were keloids. Ten months after surgery, the lesions did not exhibit marked regrowth. The keloids appeared to be caused by the patient's helmet, worn during his 3-hour daily motorcycle rides, which placed repeated tension on the periauricular area. This rare case illustrates how physical force contributes to auricular and periauricular keloid development and progression. It also shows that when performing surgery with periauricular incisions, care should be taken to eliminate wound/scar stretching.

    Bilateral cleft lips occur when the bones that form the upper lip fail to fuse at birth. Surgical reconstruction creates scars, which may lead to the following impairments: adhesions, decreased oral range of motion, decreased strength of orbicularis oris muscle, and asymmetry of oral region leading to poor self-esteem. The purpose of this case study is to determine the effectiveness of massage therapy in its ability to improve these impairments. A five-week treatment plan consisting of fascial release, kneading, and intraoral techniques. Subjective information was assessed on two scales: restriction of scar and clients attitudes and acceptance of scar. Objective information was cataloged through photographs, a palpatory chart, and a self-created "Pen Test". Results included increase range of motion and strength, decrease restrictions (palpable and subjective), and increase of symmetry. Client's perceived confidence of scar and its appearance increased. The evidence suggests that massage therapy helped with the impairments associated with scars formed by bilateral cleft lip reconstruction.

    The aim of this study is to observe if the effects of electro-acupuncture (EA) on analgesia and peripheral sensory thresholds are transposable from the model of heat pain in volunteers to the clinical setting of burn scar pain. After severe burns, pathological burn scars (PPBS) may occur with excruciating pain that respond poorly to treatment and prevent patients from wearing their pressure garments, thereby leading to unesthetic and function-limiting scars. EA might be of greater benefit in terms of analgesia and functional recovery, should it interrupt this vicious circle by counteracting the peripheral hyperalgesia characterizing PPBS. Therefore we enrolled 32 patients (22 males/10 females) aged of 46±11 years with clinical signs of PPBS and of neuropathic pain despite treatment. The study protocol consisted in 3 weekly 30-min sessions of standardized EA with extra individual needles in accordance to Traditional Chinese Medicine, in addition of previous treatments. We assessed VAS for pain and quantitative sensory testing (QST) twice: one week before and one after protocol. QST measured electrical thresholds for non-nociceptive A-beta fibers, nociceptive A-delta and C fibers in 2 dermatomes, respectively from the PPBS and from the contralateral pain-free areas. Based on heat pain studies, EA consisted in sessions at the extremity points of the main meridian flowing through PPBS (0.300s, 5Hz, sub noxious intensity, 15min) and at the bilateral paravertebral points corresponding to the same metameric level, 15min. VAS reduction of 3 points or below 3 on a 10 points scale was considered clinically relevant. Paired t-test compared thresholds (mean [SD]) and Wilcoxon test compared VAS (median [IQR]) pre and after treatment, significant ppatients - even those from the subgroup of non-responders to pain - that is worth to be mentioned and requires further studies to be confirmed.

    Full Text Available Background: Proliferative scars are benign fibrotic proliferations which demonstrate abnormal wound healing in response to skin injuries. As postulated in the “response to injury hypothesis”, atherosclerosis is also triggered by an endothelial injury. Keloid and atherosclerotic processes have many pathophysiological and cytological features in common. Aims: In this study, we investigated the relationship between proliferative scars and endothelial function in surgically revascularized patients. We aimed to test the hypothesis that atherosclerosis is a wound healing abnormality. Study Design: Cross-sectional study. Methods: Consecutive patients who were admitted to the cardiology outpatient clinic with a history of coronary artery bypass grafting operation were evaluated. Thirty-three patients with proliferative scars at the median sternotomy site formed the keloid group, and 36 age- and sex-matched patients with no proliferative scar at the median sternotomy site formed the control group. Endothelial function was evaluated by flow-mediated vasodilatation of the brachial artery via ultrasonograhic examination. Results: There is no signicant difference according to the demographic data, biochemical parameters, clinical parameters and number of grafts between keloid and control groups. Endothelial-dependent vasodilatory response was lower in the keloid group than the control group (9.30±3.5 and 18.68±8.2, respectively; p=0.001. Conclusion: This study showed that endothalial dysfunction, which is strongly correlated with atherosclerosis, was more prominent in patients with proliferative scars. As proliferative scars and atherosclerosis have many features in common, we might conclude that atherosclerosis is a wound healing abnormality.

    To analyze the cognition degree of parents of pediatric burn patients on hyperplasia of scar and its prevention and rehabilitation, so as to provide a guidance for preventing deformity and dysfunction caused by scar hyperplasia. Questionnaire survey was carried out among parents of 150 pediatric burn patients hospitalized from October 2010 to November 2011 to analyze the cognition degree of patients on the formation of scar after burns, the demand degree for scar treatment between parents of different genders of patients and among parents of patients with burn injury occurred in different body sites, the relationship between the literacy level of parents and their degree of willingness of undergoing scar treatment, and the degree of comprehension and acceptance on the part of parents regarding the methods of prevention and treatment of scar. Data were processed with chi-square test or Fisher's exact test. (1) Only the parents of 19 pediatric burn patients (accounting for 12.7%) realized the possibility of scar formation before admission. After admission, more than half of the parents were told that their children would bear scar and need regular follow-up, while only parents of 52 patients (34.7%) were instructed the methods of preventing and treating scar. (2) One hundred and forty parents (93.3%) considered their children need prevention and treatment of scar after burns. There was no statistically significant difference between parents of male patients and female patients in the demand for scar treatment (χ(2) = 0.825, P > 0.05). The demand degree of parents for rehabilitation treatment for the upper limbs after burns surpassed those of the other sites of body, and altogether there were 85 parents accounting for 97.7% of all. (3) The difference among parents with different levels of literacy was not obvious in the willingness of receiving treatment for scar hyperplasia (P > 0.05). (4) Eight methods were chosen by parents to prevent and treat scars of patients

    Full Text Available Background : Chemical reconstruction of skin scars (CROSS is a technique using high concentrations of trichloroacetic acid (TCA focally on atrophic acne scars to induce inflammation followed by collagenisation. This can lead to reduction in the appearance of scars and cosmetic improvement. Aims : The aim of this pilot study is to investigate the safety of the CROSS technique, using 100% TCA, for atrophic ice pick acne scars. Settings and Design : Open prospective study. Materials and Methods : Twelve patients with predominant atrophic ice pick post acne scars were treated with the CROSS technique, using 100% TCA, applied with a wooden toothpick, at two weekly intervals for four sittings. Efficacy was assessed on the basis of the physician′s clinical assessment, photographic evaluation at each sitting and patient′s feedback after the fourth treatment, and at the three-month and six-month follow-up period, after the last treatment. Results : More than 70% improvement was seen in eight out of ten patients evaluated and good results (50 - 70% improvement were observed in the remaining two patients. No significant side effects were noted. Transient hypopigmentation and hyperpigmentation was observed in one patient each. Physician′s findings were in conformity with the patient′s assessment. Three months after the last treatment, one patient noted a decrease in improvement with no further improvement even at the six-month follow-up period. Conclusion : The CROSS technique with 100% TCA is a safe, efficacious, cost-effective and minimally invasive technique for the management of ice pick acne scars that are otherwise generally difficult to treat. In few patients the improvement may not be sustained, probably due to inadequate or delayed collagenisation.

  17. Assessing blood flow, microvasculature, erythema and redness in hypertrophic scars: A cross sectional study showing different features that require precise definitions.

    In hypertrophic scar assessment, laser Doppler imaging (LDI), colorimetry and subjective assessment (POSAS) can be used to evaluate blood flow, erythema and redness, respectively. In addition, the microvasculature (i.e. presence of microvessels) can be determined by immunohistochemistry. These measurement techniques are frequently used in clinical practice and/or in research to evaluate treatment response and monitor scar development. However, until now it has not been tested to what extent the outcomes of these techniques are associated, whilst the outcome terms are frequently used interchangeably or replaced by the umbrella term 'vascularization'. This is confusing, as every technique seems to measure a specific feature. Therefore, we evaluated the correlations of the four measurement techniques. We included 32 consecutive patients, aged ≥18 years, who underwent elective resection of a hypertrophic scar. Pre-operatively, we performed LDI (measuring blood flow), colorimetry (measuring erythema) and the POSAS (subjective redness) within the predefined scar area of interest (∼1.5cm). Subsequently, the scar was excised and the area of interest was sent for immunohistochemistry, to determine the presence of microvessels. Only a statistically significant correlation was found between erythema values (colorimetry) and subjective redness assessment (POSAS) (r=0.403, p=0.030). We found no correlations between the outcomes of LDI, immunohistochemistry and colorimetry. Blood flow, the presence of microvessels and erythema appear to be different hypertrophic scar features because they show an absence of correlation. Therefore, in the field of scar assessment, these outcome terms cannot be used interchangeably. In addition, we conclude that the term 'vascularization' does not seem appropriate to serve as an umbrella term. The use of precise definitions in research as well as in clinical practice is recommended. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

    Actually, autologous fat grafts have many clinical applications in breast surgery, facial rejuvenation, buttock augmentation, and Romberg syndrome as well as a treatment of liposuction sequelae. The aim of this article was to describe the preparation and isolation procedures for stromal vascular fraction (SVF), the preparation of platelet-rich plasma (PRP), and the clinical application in the treatment of the scar on the face. Ten patients with burns sequelae (n = 6) and post-traumatic scars (n = 4) were treated with SVF-enhanced autologous fat grafts obtained by the Celution System. Another 10 patients with burns sequelae (n = 5) and post-traumatic scars (n = 5) were treated with fat grafting based on the Coleman technique mixed with 0.5 mL of PRP.To assess the effects of their treatment, the authors compared their results with those of a control group consisting of 10 patients treated with centrifuged fat. In the patients treated with SVF-enhanced autologous fat grafts, we observed a 63% maintenance of contour restoring after 1 year compared with only 39% of the control group (n = 10) treated with centrifuged fat graft (P < 0.0001). In the patients treated with fat grafting and PRP, we observed a 69% maintenance of contour restoring after 1 year compared with that of the control group (n = 10). Autologous fat grafting is a good method for the correction of scars on the face instead of the traditional scar surgical excision.

    Scar assessment in the clinical setting is typically impeded by a lack of quantitative data and most systems rely on subjective rating scales which are user dependant and show considerable variability between raters. The growing use of digital photography in medicine suggests a more objective approach to scar evaluation. Our objective was to determine if cameras could be of practical use for measuring colour in a clinical setting. The measurement of colour and reflectance spectra in photographs faces two difficulties: firstly the effects of variable illumination spectra, and secondly to recover accurate colour and spectral information from the sparse red, green and blue (RGB) camera signals. As a result the colour rendition is often inaccurate, and spectral information is lost. To deal with variable illumination and other factors that systematically affect all reflectance spectra ColourWorker (a method for image-based colour measurement implemented in software) calibrates the spectral responses of the camera's RGB sensors using a colour standard in the image. To make best use of the calibrated signals, it takes advantage of the fact that although a given RGB signal can be caused by an infinite number of spectra, most natural reflectance spectra vary smoothly and have predictable forms. This means given a set of examples of spectra produced by the materials of interest, it is possible to estimate the specific spectrum that produced a given RGB signal once corrected for the illumination. We describe a method for recovering spectral and chromatic information relating to surface reflectance from ordinary digital images and apply this to analyse photographs of surgical scars, taken as part of a clinical trial, in an attempt to better quantify clinical scar assessment. It should be noted the pre-existing trial protocol did not allow for a comprehensive evaluation of the accuracy of the method which would require the spectrophotometric measurement of skin regions

    Although ablative fractional resurfacing is known to be effective against photoaging and acne scars, studies on its efficacy, safety and changes in the skin characteristics of Asians are limited. The aim of this study is to assess the efficacy and safety of carbon dioxide fractional laser (CO2FL) in Koreans treated for wrinkles and acne scars, and to define the changes in skin characteristics during recovery period. We administered one session of CO2FL on 10 acne scar patients and 14 wrinkles patients with skin types IV and V. The surveillance of efficacy and side effects along with the measurement of biophysical properties was carried out before 1 day, 1 week, 1 month and 3 months after treatment. Using a non-invasive method, skin barrier damage, erythema and bronzing of skin during the recovery period were assessed, and all of the items eventually returned to the pre-treatment level. Skin elasticity was measured in the wrinkle group, and the statistically significant effect was sustained throughout the next three months. The outcome of treatment was found to be better than 'moderate improvement' in both the acne scar and wrinkle groups. Further, there were no serious side effects three months post-procedure. CO2 FL is thought to be an effective and safe method for treating moderate to severe acne scars and wrinkles in Asians.

    Full Text Available Introduction: Scars are psychologically distressing for the patients and have an impact on the quality of life and self esteem of the patients. Scar revision is an aesthetic skill which is mastered by plastic surgeons and encroached now by dermatosurgeons. Scars on the face are aesthetically unacceptable and various techniques have been improvised for making a scar aesthetically acceptable. Various types of techniques are used for scar revision like W plasty, Z plasty and VY plasty. Aims: To see the efficacy of various scar revision techniques including Z plasty, VY plasty and W plasty in 30 patients with disfiguring scars. Methods: We selected twenty patients of disfiguring scars for the study. The scars from various causes including trauma and burns were included in our study. Various techniques of scar revision include Z plasty, W plasty and VY plasty were performed according to the type and site of scar. Results: Male: female was 1.5: 1. The scar revision surgery yielded excellent results with minimal complications including haematoma formation, secondary infection and delayed healing seen in 5% patients each. Regarding the efficacy of scar revision, excellent improvement was seen in 60% patients, moderate improvement was seen in 30% patients and mild improvement was seen in 10% patients. Conclusions: Dermatologists can employ a number of surgical scar revision techniques. While some are better suited to treat specific types of scars, they can be used in combination with each other or with adjunctive therapies to achieve optimal results.

    Introduction: Non-ablative fractional erbium-doped glass 1540 nm and fractional ablative 10600 nm carbon dioxide lasers are regarded as effective modalities for treating acne atrophic scars. In this study, we aimed to compare the effectiveness of fractional CO 2 laser and fractional nonablative 1540 nm erbium doped glass laser in treating post acne atrophic scars in Egyptian patients. Methods: Fifty-eight patients complaining of moderate and severe acne atrophic scars were randomly divided into 2 groups of 29 patients each. Both groups were subjected to 4 treatment sessions with 3 weeks interval and were followed up for 3 months. In group A, enrolled patient sreceived C2 laser, while in group B, patients were treated with 1540 nm erbium glass fractional laser. Results: Clinical assessment revealed that the mean grades of progress and improvement were higher with fractional 10600 nm CO2 laser but with non-significant difference between both treatments ( P = 0.1). The overall patients' satisfaction with both lasers were not significantly different ( P = 0.44). Conclusion: Both fractional ablative CO2 and fractional non-ablative erbium glass lasers are good modalities for treating acne scars with a high efficacy and safety profile and good patient satisfaction. The fractional ablative laser showed higher efficacy while non-ablative laser offered less pain and shorter downtime.

    To compare patient-satisfaction, scar-pain and cosmesis between laparoscopic and open-cholecystectomy. Cross-sectional survey. Khyber Teaching Hospital, Peshawar, from August 2012 to May 2014. A total of 400 patients, who had undergone open or laparoscopic cholecystectomy in all units of the Surgical Department, were included. Data was collected on questionnaires given and read to the patients along with counselling and information regarding scar-pain using visual analog score, and satisfaction and cosmesis on a 0 - 10 scale, by a medical professional in the patients' native language. This was done postoperatively on patients' follow-up visits at 1 and 4 weeks. Mean scar pain score at 1 and 4 weeks postoperatively was higher for open-cholecystectomy; 4.96 ±1 and 0.96 ±1, compared to 2.24 ±0.6 and 0, respectively for laparoscopic-cholecystectomy (p < 0.001 and < 0.001). Cosmesis was higher for laparoscopic-group; 8.6 ±1.2 vs. 6.2 ±1.46 for open-cholecystectomy (p < 0.001). Patient-satisfaction was higher for laparoscopic-cholecystectomy; 9.28 ±1.5 vs. 8.32 ±2.3 for open-cholecystectomy (p < 0.001). Mean-cosmesis score was higher for laparoscopic-cholecystectomy for those younger than 40, females and unmarried. Mean patient-satisfaction score was higher for those older than 40 years who had undergone open-cholecystectomy, women who had undergone laparoscopic-cholecystectomy and for unmarried patients who had laparoscopic-cholecystectomy. Overall patient-satisfaction and cosmesis scoring was higher for laparoscopic-cholecystectomy especially among females, unmarried and younger than 40 years. Patients of 40 years and older had greater satisfaction scoring for open-cholecystectomy. Therefore, laparoscopic-cholecystectomy should be favoured in females and unmarried patients and those younger than 40 years.

    Tissue expansion is considered a major advancement in reconstructive surgery. However, there are limitations to their application in the extremities and carries relatively higher rates of complications. The aim of this study was to propose a modification to this technique and assess the rate of complications with slower rate of expansion. Thirty females (age range 14 to 40) with burn scars in the upper or lower extremity (15 cases in each) were the subjects of this investigation. Various sized rectangular expanders were used and expanded at a rate of 5% of the maximum inflatable size over 20 weeks. All of the cases of expansion completed the procedure uneventfully. In one case that developed necrosis at the edge of the flap, one week after removal of the expander, which was debrided and repaired successfully completed the treatment. Slow expansion method is a useful method which can safely be applied for burn scars in the extremities. (author)

    We used aerial photography and GIS to establish a quantitative baseline of propeller and off-road vehicle (ORV) scarring in seagrass and wind-tidal flats of the upper Laguna Madre in the Padre Island National Seashore (Texas, USA). We also examined scar recovery through comparison of recent (2002, 2005) and historical (1967) aerial photographs of the study area. Scarring intensity was calculated using two different methods. In the first, polygons were visually drawn around groups of scars on digital images. Scarring intensity was estimated as light (20%), based on the total coverage of scars within each polygon (taking into account the length, width, and density of scars). We developed a more objective method that employed creation of vector grid cells and buffers that incorporated the localized ecological impact of scars. Results of spatial and temporal analysis revealed that the polygon approach greatly underestimated the magnitude of scarring. For example, in a single photograph, 7% of seagrass area was lightly scarred according to the polygon method; but light scarring increased to 51% according to grid analysis of the same image. Our results also indicated that propeller scars in Halodule wrightii beds appear to recover in less than three years and ORV tracks have persisted in the wind-tidal flats for at least 38 years. Our approach provides resource managers with procedures for a more objective and efficient assessment of physical disturbances to seagrass and wind-tidal flats caused by boats and ORVs. ?? 2008 by Walter de Gruyter.

    We investigated whether genomic scar signatures associated with homologous recombination deficiency (HRD), which include telomeric allelic imbalance (TAI), large-scale transition (LST), and loss of heterozygosity (LOH), can predict clinical outcomes in patients with ovarian clear cell carcinoma (OCCC). We enrolled patients with OCCC (n = 80) and high-grade serous carcinoma (HGSC; n = 92) subjected to primary cytoreductive surgery, most of whom received platinum-based adjuvant chemotherapy. Genomic scar signatures based on genome-wide copy number data were determined in all participants and investigated in relation to prognosis. OCCC had significantly lower genomic scar signature scores than HGSC (p < 0.001). Near-triploid OCCC specimens showed higher TAI and LST scores compared with diploid tumors (p < 0.001). While high scores of these genomic scar signatures were significantly associated with better clinical outcomes in patients with HGSC, the opposite was evident for OCCC. Multivariate survival analysis in patients with OCCC identified high LOH scores as the main independent adverse predictor for both cancer-specific (hazard ratio [HR] = 3.22, p = 0.005) and progression-free survival (HR = 2.54, p = 0.01). In conclusion, genomic scar signatures associated with HRD predict adverse clinical outcomes in patients with OCCC. The LOH score was identified as the strongest prognostic indicator in this patient group. Genomic scar signatures associated with HRD are less frequent in OCCC than in HGSC. Genomic scar signatures associated with HRD have an adverse prognostic impact in patients with OCCC. LOH score is the strongest adverse prognostic factor in patients with OCCC.

    Beneficial effects of pressure therapy for hypertrophic scars have been reported, but the mechanisms of action are not fully understood. This study evaluated elastin and its contribution to scar pliability. The relationship between changes in Vancouver Scar Scale (VSS) scores of pressure-treated scars and differential regulation of elastin was assessed. Hypertrophic scars were created and assessed weekly using VSS and biopsy procurement. Pressure treatment began on day 70 postinjury. Treated scars were compared with untreated shams. Treatment lasted 2 weeks, through day 84, and scars were assessed weekly through day 126. Transcript and protein levels of elastin were quantified. Pressure treatment resulted in lower VSS scores compared with sham-treated scars. Pliability (VSSP) was a key contributor to this difference. At day 70 pretreatment, VSSP = 2. Without treatment, sham-treated scars became less pliable, while pressure-treated scars became more pliable. The percentage of elastin in scars at day 70 was higher than in uninjured skin. Following treatment, the percentage of elastin increased and continued to increase through day 126. Untreated sham scars did not show a similar increase. Quantification of Verhoeff-Van Gieson staining corroborated the findings and immunofluorescence revealed the alignment of elastin fibers. Pressure treatment results in increased protein level expression of elastin compared with sham-untreated scars. These findings further characterize the extracellular matrix's response to the application of pressure as a scar treatment, which will contribute to the refinement of rehabilitation practices and ultimately improvements in functional and psychosocial outcomes for patients.

    OBJECTIVES: To compare the scar outcome of video-assisted parathyroidectomy (VAP) with traditional bilateral cervical exploration (BCE) using previously validated scar assessment scales, and to examine the feasibility of introducing VAP into a general otolaryngology-head and neck practice. DESIGN: A retrospective review of medical records from a prospectively obtained database of patients and long-term follow-up of scar analysis. PATIENTS: The records of 60 patients undergoing parathyroidectomy were reviewed: 29 patients underwent VAP and 31 patients underwent an open procedure with BCE. The groups were matched for age and sex. A total of 46 patients were followed up to assess scar outcome. MAIN OUTCOME MEASURES: The primary outcome was a comparison of patient and observer scar satisfaction between VAP and traditional BCE using validated scar assessment tools: the Patient Scar Assessment Scale and the Manchester Scar Scale. The secondary outcomes were to retrospectively evaluate our results with VAP and to assess the suitability of introducing this technique into a general otolaryngology-head and neck practice. RESULTS: The average scar length in the VAP group was 1.7 cm, and the average scar length in the BCE group was 4.3 cm. The patients in the BCE group scored higher than the patients in the VAP group on the Manchester Scar Scale (P < .01) and on the Patient and Observer Scar Scales (P = .02), indicating a worse scar outcome. The mean operative time in the VAP group was 41 minutes compared with 115 minutes in the open procedure BCE group. There was no difference between the 2 groups in terms of postoperative complications. CONCLUSIONS: Video-assisted parathyroidectomy is a safe and feasible procedure in the setting of a general otolaryngology-head and neck practice, with outcomes and complication rates that are comparable to those of traditional bilateral neck exploration. Both patient and observer analysis demonstrated that VAP was associated with a more

    Medical evidence indicates that 60-80% of women can achieve vaginal delivery after a previous lower segment caesarean section. Proper selection of patients for trial of scar and vigilant monitoring during labour will achieve successful maternal and perinatal outcome. The objective of our study is to establish the fact that vaginal delivery after one caesarean section has a high success rate in patients with previous one caesarean section for non-recurrent cause. Methods: The study was conducted in Ayub Teaching Abbottabad, Gynae-B Unit. All labouring patients, during the study period of five years, with previous one caesarean section and between 37 weeks to 41 weeks of gestation for a non-recurrent cause were included in the study. Data was recorded on special proforma designed for the purpose. Patients who had previous classical caesarean section, more than one caesarean section, and previous caesarean section with severe wound infection, transverse lie and placenta previa in present pregnancy were excluded. Foetal macrosomia (wt>4 kg) and severe IUGR with compromised blood flow on Doppler in present pregnancy were also not considered suitable for the study. Patients who had any absolute contraindication for vaginal delivery were also excluded. Results: There were 12505 deliveries during the study period. Total vaginal deliveries were 8790 and total caesarean sections were 3715. Caesarean section rate was 29.7%. Out of these 8790 patients, 764 patients were given a trial of scar and 535 patients delivered successfully vaginally (70%). Women who presented with spontaneous onset of labour were more likely to deliver vaginally (74.8%) as compared to induction group (27.1%). Conclusion: Trial of vaginal birth after caesarean (VBAC) in selected cases has great importance in the present era of the rising rate of primary caesarean section. (author)

    Intralesional (IL) cryotherapy is a new promising technique for the treatment of keloid scars, in which the scar is frozen from inside. Multiple devices are available, mostly based on a simple liquid nitrogen Dewar system, which have a limited freezing capacity. Argon gas-based systems ensure accurate and highly controlled freezing and have shown to be effective within the field of oncologic surgery. However, this technique has never been used for the treatment of keloid scars. This prospective study evaluates an argon gas-based system for the treatment of keloids in a patient population including all Fitzpatrick skin types with a 1-year follow-up. Twenty-five patients with 30 keloid scars were included and treated with a device called Seednet (Galil Medical, Yokneam, Israel). Scar quality and possible scar recurrence were assessed before treatment and post treatment (6 and 12 months) with objective devices determining scar color, scar elasticity, scar volume, and patient's skin type. In addition, scars were evaluated using the Patient and Observer Scar Assessment Scale. After 12 months, a significant volume reduction of 62% was obtained, p = 0.05. Moreover, complaints of pain and itching were alleviated and scar quality had improved according to the Patient and Observer Scar Assessment Scale. Scar pigmentation recovered in 62% of all keloid scars within 12 months. Five out of 30 (17%) scars recurred within 12 months, three of which had previously been treated with liquid nitrogen-based IL cryotherapy. Both recurrent and persistent hypopigmentation were mainly seen in Afro-American patients. IL cryotherapy with the use of an argon gas-based system proves to be effective in the treatment of keloid scars, yielding volume reduction and low recurrence rates. Although hypopigmentation recovered in most cases, it is strongly related to non-Caucasian patients. Finally, additional treatment of keloid scars previously unresponsive to IL cryotherapy is predisposed to a high

    Left atrial (LA) scarring, a consequence of cardiac fibrosis is a powerful predictor of procedure-outcome in atrial fibrillation (AF) patients undergoing catheter ablation. We sought to compare the long-term outcome in patients with paroxysmal AF (PAF) and severe LA scarring identified by 3D mapping, undergoing pulmonary vein isolation (PVAI) only or PVAI and the entire scar areas (scar homogenization) or PVAI+ ablation of the non-PV triggers. Totally, 177 consecutive patients with PAF and severe LA scarring were included. Patients underwent PVAI only (n = 45, Group 1), PVAI+ scar homogenization (n = 66, Group 2) or PVAI+ ablation of non-PV triggers (n = 66, Group 3) based on operator's choice. Baseline characteristics were similar across the groups. After first procedure, all patients were followed-up for a minimum of 2 years. The success rate at the end of the follow-up was 18% (8 pts), 21% (14 pts), and 61% (40 pts) in Groups 1, 2, and 3, respectively. Cumulative probability of AF-free survival was significantly higher in Group 3 (overall log-rank P homogenization. Published on behalf of the European Society of Cardiology.

    Objective The primary goal of this study was to evaluate a nonlinear dynamic approach to the acoustic analysis of dysphonia associated with vocal fold scar and sulcus vocalis. Study Design Case-control study. Methods Acoustic voice samples from scar/sulcus patients and age/sex-matched controls were analyzed using correlation dimension (D2) and phase plots, time-domain based perturbation indices (jitter, shimmer, signal-to-noise ratio [SNR]), and an auditory-perceptual rating scheme. Signal typing was performed to identify samples with bifurcations and aperiodicity. Results Type 2 and 3 acoustic signals were highly represented in the scar/sulcus patient group. When data were analyzed irrespective of signal type, all perceptual and acoustic indices successfully distinguished scar/sulcus patients from controls. Removal of type 2 and 3 signals eliminated the previously identified differences between experimental groups for all acoustic indices except D2. The strongest perceptual-acoustic correlation in our dataset was observed for SNR; the weakest correlation was observed for D2. Conclusions These findings suggest that D2 is inferior to time-domain based perturbation measures for the analysis of dysphonia associated with scar/sulcus; however, time-domain based algorithms are inherently susceptible to inflation under highly aperiodic (i.e., type 2 and 3) signal conditions. Auditory-perceptual analysis, unhindered by signal aperiodicity, is therefore a robust strategy for distinguishing scar/sulcus patient voices from normal voices. Future acoustic analysis research in this area should consider alternative (e.g., frequency- and quefrency-domain based) measures alongside additional nonlinear approaches. PMID:22516315

  16. Incidental Syringomas of the Scalp in a Patient with Scarring Alopecia

    Directory of Open Access Journals (Sweden)

    Kristyn Deen

    2015-07-01

    Full Text Available Syringomas are benign adnexal neoplasms of eccrine lineage, which occur most commonly in the periorbital region in middle-aged females. These cutaneous lesions rarely occur on the scalp, are typically asymptomatic and are predominantly of cosmetic significance. Involvement of the scalp may be indistinguishable from that of scarring alopecia. We present an unusual case of clinically inapparent syringomas occurring on the scalp of a 56-year-old female with alopecia who was subsequently diagnosed with lichen planopilaris after repeated scalp biopsy. In patients with unexplained hair loss, or in cases that are refractive to treatment, clinicians should perform scalp biopsy to exclude the diagnosis of rare neoplastic lesions like syringomas and to diagnose associated conditions.

    Clinical indications for vocal fold injection augmentation (VFI) are expanding. Prior studies demonstrate the benefit of trial VFI for select causes of glottic insufficiency. No studies have examined trial VFI for glottic insufficiency resulting from true vocal fold (TVF) scar. Retrospective chart review of patients who underwent trial VFI for a dominant pathology of TVF scar causing dysphonia. Patients who subsequently underwent durable augmentation were identified. The primary study outcome was the difference in Voice Handicap Index-10 (VHI-10) score from pretrial VFI to post-durable augmentation. Twenty-eight patients underwent trial VFI for TVF scar, 22 of whom reported a positive response. Fifteen of 22 subjects who underwent durable augmentation had viable data for analysis. Mean VHI-10 improved from 26.9 to 18.6 ( P 5). A trial VFI is a potentially useful, low-risk procedure that appears to help the patient and clinician identify when global augmentation might improve the voice when vocal fold scar is present. Patients who reported successful trial VFI often demonstrated significant improvement in their VHI-10 after subsequent durable augmentation.

    To validate a prediction model for successful vaginal birth after Cesarean delivery (VBAC) based on sonographic assessment of the hysterotomy scar, in a Swedish population. Data were collected from a prospective cohort study. We recruited non-pregnant women aged 18-35 years who had undergone one previous low-transverse Cesarean delivery at ≥ 37 gestational weeks and had had no other uterine surgery. Participants who subsequently became pregnant underwent transvaginal ultrasound examination of the Cesarean hysterotomy scar at 11 + 0 to 13 + 6 and at 19 + 0 to 21 + 6 gestational weeks. Thickness of the myometrium at the thinnest part of the scar area was measured. After delivery, information on pregnancy outcome was retrieved from hospital records. Individual probabilities of successful VBAC were calculated using a previously published model. Predicted individual probabilities were divided into deciles. For each decile, observed VBAC rates were calculated. To assess the accuracy of the prediction model, receiver-operating characteristics curves were constructed and the areas under the curves (AUC) were calculated. Complete sonographic data were available for 120 women. Eighty (67%) women underwent trial of labor after Cesarean delivery (TOLAC) with VBAC occurring in 70 (88%) cases. The scar was visible in all 80 women at the first-trimester scan and in 54 (68%) women at the second-trimester scan. AUC was 0.44 (95% CI, 0.28-0.60) among all women who underwent TOLAC and 0.51 (95% CI, 0.32-0.71) among those with the scar visible sonographically at both ultrasound examinations. The prediction model demonstrated poor accuracy for prediction of successful VBAC in our Swedish population. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd. Copyright © 2017 ISUOG.

    Six patients with radiation scars are described. In each case the diagnosis was confirmed histologically in five cases corresponding mammograms were available. The histological appearances of radiation scars are described and the radiological features are presented. These lesions can be diagnosed mammographically in vivo. Macroscopically differentiation from a scirrhous carcinoma is not possible and therefore a radiation scar must always be excised; this also leads to definitive cure. On mammographic screening the incidence is 0.5 to 0.9 per thousand. The significance of radiation scars depends on the fact that they are pre-cancerous and therefore are equivalent to the early diagnosis of a carcinoma with the possibility of a complete cure. (orig.)

    Objective: To explore influence of the WeChat platform on the compliance of continuous treatment of scar in adult burn patients. Methods: A total of 124 adult burn patients, conforming to the study criteria, admitted in the Department of Burns of our hospital from January 2015 to January 2016 were divided into WeChat group ( n =63) and control group ( n =61) according to the random number table. Patients in control group only received regular discharging rehabilitation guide, while patients in WeChat group received regular discharging rehabilitation guide and joined WeChat platform after being discharged from hospital. Through pushing rehabilitation plan and rehabilitation related knowledge, organizing support discussion of burn patients, answering the patients' questions, members of WeChat platform intervention group conducted continuous treatment for 6 months on patients of WeChat group. The compliance of functional exercise of patients in two groups in one week before discharge and 3 and 6 months after discharge was evaluated by using the self-made functional exercise compliance log sheet. The compliance of using anti-scar drug and appliance of patients in two groups in 3 and 6 months after discharge was evaluated by using self-made anti-scar drug and appliance usage log sheets. Data were processed with chi-square test, independent sample t test, non-parametric rank sum test of independent sample, and Wilcoxon rank sum test. Results: (1) The compliance ratio of functional exercise of patients in WeChat group (95.24%, 60/63) was close to 93.44% (57/61) in control group in one week before discharge ( χ (2)=0.188, P >0.05). The compliance ratios of functional exercise of patients in WeChat group were respectively 93.65% (59/63) and 87.30% (55/63) in 3 and 6 months after discharge, which were higher than 68.85% (42/61) and 65.57% (40/61) in control group ( χ (2)=12.615, 8.166, P WeChat group was significantly better than that in control group in 3 and 6 months

    This cross-sectional pilot-study investigated the reproducibility of the LDI (Moor-LDI-B2; Moor Instruments) and the chromameter (Minolta chromameter CR-300) when used in scar assessment. Twenty-seven scars in 14 subjects were included between January and June 2003. One observer performed two times both measurements with 10 min apart. The intra-observer agreement is quantified by means of the intra-class correlations (ICC) and the standard errors of measurement (SEM) for both the LDI and the chromameter. Ignoring one outlier, the ICC of the LDI = 0.856 and the SEM = 34.56. The chromameter shows a better reproducibility with an ICC of 0.93 and a SEM of 0.79. This pilot-study with a limited number of measurements shows a moderate reproducibility of the LDI compared to the chromameter measurements, in the assessment of respectively flux and redness in scars. © 2011 John Wiley & Sons A/S.

    To evaluate the effect of burn rehabilitation massage therapy on hypertrophic scar after burn. One hundred and forty-six burn patients with hypertrophic scar(s) were randomly divided into an experimental group and a control group. All patients received standard rehabilitation therapy for hypertrophic scars and 76 patients (massage group) additionally received burn scar rehabilitation massage therapy. Both before and after the treatment, we determined the scores of visual analog scale (VAS) and itching scale and assessed the scar characteristics of thickness, melanin, erythema, transepidermal water loss (TEWL), sebum, and elasticity by using ultrasonography, Mexameter(®), Tewameter(®), Sebumeter(®), and Cutometer(®), respectively. The scores of both VAS and itching scale decreased significantly in both groups, indicating a significant intragroup difference. With regard to the scar characteristics, the massage group showed a significant decrease after treatment in scar thickness, melanin, erythema, TEWL and a significant intergroup difference. In terms of scar elasticity, a significant intergroup difference was noted in immediate distension and gross skin elasticity, while the massage group significant improvement in skin distensibility, immediate distension, immediate retraction, and delayed distension. Our results suggest that burn rehabilitation massage therapy is effective in improving pain, pruritus, and scar characteristics in hypertrophic scars after burn.

    Recurrent keloid scarring has a significant impact on quality of life. Management is complex, particularly for scars resistant to conventional treatments and in paediatric cases where radiotherapy is not a suitable adjunct to surgical excision. We present the case of a nine-year-old African Caribbean girl with multiple large and recurrent keloid scars on both ears and bilateral sensorineural deafness. Following repeated intralesional excisions, corticosteroid and botulinum toxin injections, she continued to experience rapid recurrence of her keloids, worsening pain and pruritus. She was no longer able to wear her hearing aids because of the large size of the keloids. We employed a novel technique using topical intralesional cryotherapy, applying liquid nitrogen intraoperatively to the inside of the skin flaps immediately post-intralesional keloid excision and before wound closure. At 26-month follow-up a good aesthetic and symptomatic result was achieved, with minimal hypopigmentation, significantly reduced scar volume and significantly slowed recurrence. We discuss this case and review the current literature on the use of topical intralesional cryotherapy for keloid scarring.

    We evaluated the predictors of renal scar in children with urinary tract infections (UTIs) having primary vesicoureteral reflux (VUR). Data of patients who were examined by dimercaptosuccinic acid (DMSA) scintigraphy between 1995 and 2005 were evaluated retrospectively. Gender, age, reflux grade, presence/development of scarring, breakthrough UTIs, and resolution of reflux, were recorded. The relation of gender, age and VUR grade to preformed scarring and the relation of gender, age, VUR grade, presence of preformed scarring, number of breakthrough UTIs and reflux resolution to new scarring were assessed. There were 138 patients [male/female (M/F) 53/85]. Multivariate analysis showed that male gender [odds ratio (OR) 2.5], age > or = 27 months in girls (OR 4.2) and grades IV-V reflux (OR 12.4) were independent indicators of renal scarring. On the other hand, only the presence of previous renal scarring was found to be an independent indicator for the development of new renal scar (OR 13.4). In conclusion, while the most predictive variables for the presence of renal scarring among children presenting with a UTI were male gender, age > or = 27 months in girls, and grades IV-V reflux, the best predictor of new scar formation was presence of previous renal scarring.

    MRI-guided wire localization is commonly used for surgical localization of breast lesions. Here we introduce an alternative use of this technique to help with surgical resection of a recurrent pleomorphic sarcoma embedded in extensive post-treatment scar tissue. We describe a case of recurrent pleomorphic soft tissue sarcoma in the thigh after treatment with neoadjuvant therapy, surgery, and radiation. Due to the distortion of the normal tissue architecture and formation of extensive scar tissue from prior treatment, wire localization under MRI was successfully used to assist the surgeon in identifying the recurrent tumor for removal.

    A study was made of the X-ray picture of the stomach postulcer scar in correlation with fibrogastroscopy in 39 patients. The X-ray picture was characterized by considerable polymorphism and at the same time it was difficult to single out pathognomonic features. For specified diagnosis and differentiation the detection of the postulcer scar must become a multifaceted roentgenoendoscopic problem. Stomach ulcers may scar, sometimes with the complete regeneration of the mucosa relief, however their recurrences can develop in the zone of the postulcer scar

    Acne scarring can be classified into atrophic icepick, boxcar, and rolling scars in addition to keloidal and hypertrophic scars. Additionally, these scars can be erythematous, hyperpigmented, and/or hypopigmented. Each scar type has a different structural cause warranting a customized approach. Many cosmetic options exist to address these changes individually, but little literature exists about the safety and efficacy of combining such procedures and devices. A Medline search was performed on combination treatments because it relates to facial acne scarring, and results are summarized. Practical applications for these combinations of procedures are also discussed. Studies examining the efficacy and safety of ablative, nonablative, fractionated, and nonfractionated lasers, dermabrasion, chemical peels, needling, subcision, radiofrequency, stem cell therapy, fat transplantation, platelet-rich plasma, and hyaluronic acid dermal fillers for acne scars were found. The authors review their experience in combining these techniques. Review of the literature revealed multiple single options for facial acne scarring treatment with minimal evidence in the literature found on the safety and efficacy of combining such procedures and devices. The authors' experience is that combining acne scar treatment techniques can be performed safely and synergistically with optimal patient outcomes.

    Surgical management of benign or malignant cutaneous tumors may result in noticeable scars that are of great concern to patients, regardless of sex, age, or ethnicity. Techniques to optimize surgical scars are discussed in this three-part review. Part 2 focuses on scar revision for hypertrophic and keloids scars. Scar revision options for hypertrophic and keloid scars include corticosteroids, bleomycin, fluorouracil, verapamil, avotermin, hydrogel scaffold, nonablative fractional lasers, ablative and fractional ablative lasers, pulsed dye laser (PDL), flurandrenolide tape, imiquimod, onion extract, silicone, and scar massage.

  11. Fractional ablative CO2 laser treatment versus scar subcision and autologous fat transfer in the treatment of atrophic acne scars: New technique

    2016-04-01

    Full Text Available There are different modalities for management of atrophic acne scars which include lasers. Ablative fractional CO2 laser was developed to address the shortcomings of traditional ablative lasers, with superior results to non-ablative fractional lasers. Autologous fat transfer has been utilized for nearly a decade in tissue augmentation and reconstruction.Present studies were designed to compare ablative fractional CO2 laser treatment with scar subcision and autologous fat transfer in the treatment of atrophic acne scars. 20 patients with atrophic acne scars were recruited: 10 patients were treated by three sessions of ablative fractional CO2 laser therapy, and 10 patients treated by subcision and autologous fat transfer. All patients were followed up for three months, and were assessed by digital photograph before and after treatment through the application of Goodman and Baron quantitative and qualitative grading systems, in addition to reports by three physicians committees and reports of patients’ satisfaction. Analysis of both groups showed significant improvements in all types of atrophic acne scars. The mean percentage of total quantitative improvement was more significant in the case of autologous fat transfer with regard to ice-pick and total number of scars. Therefore, scar subcision with autologous fat transfer proved to be as effective as, or even more effective than, ablative fractional CO2 laser in the treatment of atrophic acne scars with regard to the total number of scars as well as ice-pick type.

    The evaluation of scar colour is, at present, usually limited to an assessment according to a scar assessment scale. Although useful, these assessment scales only evaluate subjectively the degree of scar colour. In this study, the reliability of the subjective assessment of scar colour by observers is compared to the reliability of the measurements of two objective colour measurement instruments. Four independent observers subjectively assessed the vascularisation and pigmentation of 49 scar areas in 20 patients. The degree of vascularisation and pigmentation was scored according to a scale ranging from '1', when it appeared to be like healthy skin, to '10', which corresponds to the worst imaginable outcome of vascularisation or pigmentation. The observers also scored the pigmentation categories of the scar (hypopigmention, hyperpigmention or mixed pigmentation). Finally, each observer measured the scar areas with a tristimulus colorimeter (Minolta Chromameter) and a narrow-band simple reflectance meter (DermaSpectrometer). A single observer could reliably carry out measurements of the DermaSpectrometer and the Minolta Chromameter for the evaluation of scar colour (r = 0.72). The vascularisation of scars could also be assessed reliably with a single observer (r = 0.76) whereas for a reliable assessment of pigmentation at least three observers were necessary (r > or = 0.77). The agreement between the observers for the pigmentation categories also turned out to be unacceptably low (k = 0.349). This study shows that an overall evaluation of scar colour with the DermaSpectrometer and the Minolta Chromameter is more reliable than the evaluation of scar colour with observers. Of both instruments for measuring scar colour, we prefer, because of its feasibility, the DermaSpectrometer.

    It is commonly accepted that burns taking longer than 3 weeks to heal have a much higher rate of hypertrophic scarring than those which heal more quickly. However, some of our patients develop hypertrophic scars despite healing within this 3-week period. We performed a prospective study of 383 paediatric burns treated non-operatively at a regional burns centre over a 2-year period from May 2011 to April 2013. Scar assessment was performed by a senior burns therapist using the Vancouver Scar Scale. Overall rates of hypertrophic scarring were 17.2%. Time to healing was the strongest predictor of developing hypertrophic scarring, and the earliest hypertrophic scar developed in a patient who was healed after 8 days. The risk of hypertrophic scarring was multiplied by 1.138 for every additional day taken for the burn wound to heal. There was a trend towards higher rates of hypertrophic scarring in non-white skin types but this did not reach statistical significance. The risk of hypertrophic scarring increases with every day and, therefore, every effort should be made to get the wound healed as quickly as possible, even within the traditional 3-week period usually allowed for healing. We believe that the traditional dogma of aiming for healing within 3 weeks is overly simplistic and should be abandoned: in paediatric burns, every day counts. Not applicable.

    Keloids and hypertrophic scars are extremely disturbing to patients, both physically and psychologically. This study prospectively assessed the safety and efficacy of intense pulsed light (IPL) on scars originating from burns, trauma, surgery, and acne. Hypertrophic scars in 109 patients, originating from surgical incisions (n = 55), traumatic cuts (traffic accidents) (n = 24), acne scars (n = 6), keloids (n = 5), and burns (n = 19), were treated using an IPL Quantum device. Treatment was administered at 2-4-week intervals, and patients received an average of 8 treatments (range = 6-24). Using digital photographs, Changes in scar appearance were assessed by two physicians who were blinded to the study patients and treatments. The photographs were graded on a scale of 0 to 4 (none, minimal, moderate, good, excellent) for improvement in overall clinical appearance and reduction in height, erythema, and hardness. An overall clinical improvement in the appearance of scars and reductions in height, erythema, and hardness were seen in the majority of the patients (92.5%). Improvement was excellent in 31.2% of the patients, good in 25.7%, moderate in 34%, and minimal in 9.1%. Over half the patients had good or excellent improvement. In the preventive IPL treatment group, 65% had good to excellent improvement in clinical appearance. Patient satisfaction was very high. This study suggests that IPL is effective not only in improving the appearance of hypertrophic scars and keloids regardless of their origin, but also in reducing the height, redness, and hardness of scars.

    To determine prevalence and risk factors for renal scar in children referred for urologic assessment of febrile UTI and/or VUR. Pre-determined risk factors for renal scar were prospectively recorded in consecutive patients referred for UTI/VUR. Age, gender, VUR grade, and reported number of febrile and non-febrile UTIs were analyzed with logistic regression to determine risk for focal cortical defects on non-acute DMSA. Of 565 consecutive children, 24 (4%) had congenital renal dysplasia and 84 (15.5%) had focal defect(s). VUR, especially grades IV-V, recurrent febrile UTI, and older age increased risk. For any age child with the same number of UTIs, VUR increased odds of renal defect 5.4-fold (OR = 5.4, 95% CI = 2.7-10.6, AUC = 0.759). Focal DMSA defects were present in 15.5% of 565 consecutive children referred for febrile UTI and/or VUR; 4% had presumed congenital reflux nephropathy without cortical defect. All VUR grades increased risk for these defects, as did recurrent febrile UTIs and older age. However, 43% with grades IV-V VUR and 76% with recurrent UTI had normal DMSA. Published by Elsevier Ltd.

    2014-01-01

    Full Text Available Background: Various treatment modalities including non-invasive methods such as chemical peels, topical retinoids, microdermabrasion, minimally invasive techniques such as microneedling, fractional lasers, microneedling radiofrequency devices and invasive procedures such as acne scar surgeries and ablative lasers are used for acne scars, each with its own unique advantages and disadvantages. This study is a retrospective assessment of efficacy and safety of microneedling fractional radiofrequency in the treatment of acne scars. Methods: Thirty one patients of skin types III-V with moderate and severe facial acne scarring received four sequential fractional radiofrequency treatments over a period of 6 months with an interval of 6 weeks between each session. Goodman & Baron′s acne scar grading system was used for assessment by a side by side comparison of preoperative and post- operative photographs taken at their first visit and at the end of 3 months after the last session. Results: Estimation of improvement with Goodman and Baron′s Global Acne Scarring System showed that by qualitative assessment of 31 patients with grade 3 and grade 4 acne scars, 80.64% showed improvement by 2 grades and 19.35% showed improvement by 1 grade. Quantitative assessment showed that 58% of the patients had moderate, 29% had minimal, 9% had good and 3% showed very good improvement. Adverse effects were limited to transient pain, erythema, edema and hyperpigmentation. Conclusion: Microneedling fractional radiofrequency is efficacious for the treatment of moderate and severe acne scars.

    Purpose: Evaluation of the results of perioperative interstitial brachytherapy with low dose-rate (L.D.R.) Ir-192 in the treatment of keloid scars. Patients and methods: We performed a retrospective analysis of 73 histologically confirmed keloids (from 58 patients) resistant to medico surgical treated by surgical excision plus early perioperative brachytherapy. All lesions were initially symptomatic. Local control was evaluated by clinical evaluation. Functional and cosmetic results were assessed in terms of patient responses to a self-administered questionnaire. Results: Median age was 28 years (range 13-71 years). Scars were located as follows: 37% on the face, 32% on the trunk or abdomen, 16% on the neck, and 15% on the arms or legs. The mean delay before loading was four hours (range, 1-6 h). The median dose was 20 Gy (range, 15-40 Gy). Sixty-four scars (from 53 patients) were evaluated. Local control was 86% (follow-up, 44.5 months; range, 14-150 months). All relapses occurred early within 2 years posttreatment. At 20 months, survival without recurrence was significantly lower when treated lengths were more than 6 cm long. The rate was 100% for treated scars below 4.5 cm in length, 95% (95% CI: 55-96) for those 4.5-6 cm long, and 75% (95% CI: 56-88) beyond 6 cm (p = 0.038). Of the 35 scars (28 patients) whose results were reassessed, six remained symptomatic and the esthetic results were considered to be good in 51% (18/35) and average in 37% (13/35) (median follow-up, 70 months; range, 16-181 months). Conclusion: Early perioperative L.D.R. brachytherapy delivering 20 Gy at 5 mm reduced the rate of recurrent keloids resistant to other treatments and gave good functional results. (authors)

    Full Text Available Introduction Fibrotic scar formation is a main cause of recurrent urethral stricture after initial management with direct vision internal urethrotomy (DVIU. In the present study, we devised a new technique of combined the transurethral resection of fibrotic scar tissue and temporary urethral stenting, using a thermo-expandable urethral stent (MemokathTM 044TW in patients with anterior urethral stricture. Materials and Methods As a first step, multiple incisions were made around stricture site with cold-cutting knife and Collins knife electrode to release a stricture band. Fibrotic tissue was then resected with a 13Fr pediatric resectoscope before deployment of a MemokathTM 044TW stent (40 – 60mm on a pre-mounted sheath using 0° cystoscopy. Stents were removed within 12 months after initial placement. Results We performed this technique on 11 consecutive patients with initial (n = 4 and recurrent (n = 7 anterior urethral stricture (April 2009 – February 2013. At 18.9 months of mean follow-up (12-34 months, mean Qmax (7.8±3.9ml/sec vs 16.8 ± 4.8ml/sec, p < 0.001, IPSS (20.7 vs 12.5, p = 0.001 , and QoL score (4.7 vs 2.2, p < 0.001 were significantly improved. There were no significant procedure-related complications except two cases of tissue ingrowth at the edge of stent, which were amenable by transurethral resection. In 7 patients, an average 1.4 times (1-5 times of palliative urethral dilatation was carried out and no patients underwent open surgical urethroplasty during the follow-up period. Conclusion Combined transurethral resection and temporary urethral stenting is a effective therapeutic option for anterior urethral stricture. Further investigations to determine the long-term effects, and safety profile of this new technique are warranted.

    This study assessed the role of self-reported facial scar severity as a possible influencing factor on self-esteem and depressive symptoms in patients with facial burns. A prospective multicentre cohort study with a 6 months follow-up was conducted including 132 patients with facial burns. Patients completed the Patient and Observer Scar Assessment Scale, the Rosenberg Self-esteem Scale and the Hospital Anxiety and Depression Scale. Structural Equation Modeling was used to assess the relations between depressive symptoms, self-esteem and scar severity. The model showed that patient-rated facial scar severity was not predictive for self-esteem and depressive symptoms six months post-burn. There was, however, a significant relationship between early depressive symptoms and both patient-rated facial scar severity and subsequent self-esteem. The variables in the model accounted for 37% of the variance in depressive symptoms six months post-burn and the model provided a moderately well-fitting representation of the data. The study suggests that self-esteem and depressive symptoms were not affected by self-reported facial scar severity but that earlier depressive symptoms were indicative for a more severe self-reported facial scar rating. Therefore, routine psychological screening during hospitalisation is recommended in order to identify patients at risk and to optimise their treatment. Copyright © 2014 Elsevier Inc.

    Full Text Available BackgroundOpen thyroidectomy is conventionally performed at the anterior side of neck, which is a body part with a comparatively great degree of open exposure; due to this, postoperative scarring may cause distress in patients. We aimed to compare the effects of ablative and nonablative fractional laser treatments on thyroidectomy scars. We examined medical records in a retrospective manner and analyzed scars based on their digital images by using the modified Manchester Scar Scale (mMSS.MethodsBetween February 2012 and May 2013, 55 patients with thyroidectomy scars were treated with ablative (34 patients or nonablative (21 patients fractional laser. Each patient underwent 4 laser treatment sessions in 3–4 week intervals, 1–2 months postoperatively. Scar improvement was assessed using patient images and the mMSS scale.ResultsThe mean decrease in scar score was 3.91 and 3.47 in the ablative and nonablative groups, respectively; the reduction between 2 groups did not exhibit any significant difference (P=0.16. We used the scale once again to individually evaluate scar attributes. The nonablative group accounted for a considerably higher color score value (P=0.03; the ablative group accounted for a considerably higher contour score value (P<0.01. Patient satisfaction was high and no complications occurred.ConclusionsBoth types of fractional laser treatments can be used successfully for thyroidectomy scar treatment with minimal complications; however, results indicate that higher effectiveness may be obtained from the use of ablative and nonablative lasers for hypertrophic scars and early erythematous scars, respectively. Therefore, the appropriate laser for scar treatment should be selected according to its specific characteristics.

    Full Text Available Introduction. Platelet-rich plasma (PRP is a product widely used in sports medicine, tissue repair, and general surgery. A recent meta-analysis showed this product to be beneficial when introduced into a wound area, be it intra-articular (i.e., joint-injections or direct introduction onto the wound surface. Methods. Between the years of 2012 and 2014 a questionnaire evaluating surgical outcome after port (venous access device removal was answered by 100 patients in the control group and 20 patients in a PRP group, leading to a total of 120 patients in this single center, retrospective, subjective outcome evaluation. Results. No statistical difference was shown in postsurgical complication rates, postsurgical pain, decreased mobility, and overall quality of life. A significant difference was shown in overall patient satisfaction and the desire to further improve port area scarring. Results differed significantly in favor of the PRP group. Interestingly, approximately 40.2% of patients are dissatisfied with the surgical outcome after port removal in the control group. This result, though surprising, may be improved to 10% dissatisfaction when a PRP product is used. Conclusion. PRP products such as Arthrex ACP are safe to use and present an additional option in improving surgical outcome.

    Full Text Available Background: While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. Aim: The aim of the present study is to assess the efficacy and safety of fractional CO 2 laser resurfacing in atrophic facial acne scars. Materials and Methods: Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO 2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as ′excellent′ if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as ′good′ and ′poor′ response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Results: Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3% while 15 (25% and 19 patients (31.7% demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Conclusions: Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar

    Clinically confirmed incidents of acute pyelonephritis (APN) following recurrent infections of urinary tract (UTI) form basic risk factors for renal scarring in children. Vesico-uretheral reflux (VUR) of higher grade is additional risk factor for this scarring. Opinions on diagnostic value of summed sequential images of renal uptake phase (SUM) of dynamic renal scintigraphy in detection of renal scars are diverse. However, several publications point to higher diagnostic efficacy of clearance parametric images (PAR) generated from this study. To establish a clinical value of parametric renal clearance images in detection of renal scarring. A prospective study was performed in a group of 91 children at the age of 4 to 18 years with recurrent UTI. Clinically documented incidents of APN were noted in 32 children: in 8 cases - one and in the remaining 24 - 2 to 5 (mean 3) incidents. In the remaining 59 patients only infections of the lower part of urinary tract were diagnosed. Static renal 99mTc-DMSA SPECT study and after 2-4 days dynamic renal studies (99mTc-EC) were performed in every patient not earlier than 6 months after the last documented incident of UTI. PAR images generated from a dynamic study by in-house developed software and SUM images were compared with a gold standard SPECT study. Percentages of children with detected renal scar(s) with SPECT and PAR methods amounted to 55% and 54%, respectively and were statistically significantly higher (p children with history of APN detected with SPECT and PAR methods were significantly more frequent than with infections of only lower part of urinary tract (72% vs. 46%; p = 0.017 and 69% vs. 46%; p = 0.036, respectively). A SUM method did not reveal statistically significant differences between frequencies of detection of scars in groups specified above - 38% vs. 27% (p = 0.31). Both SPECT and PAR methods showed also that frequencies of occurrence of renal scars in children with higher grades of VUR were higher than

    ESWL is now widely used for the treatment of renal stone disease. Although ESWL has many advantages for patients' quality of life, few reports have demonstrated the long-term outcomes of the alterations of renal morphology after ESWL. We reported renal scarring after ESWL monotherapy in patients with renal calyceal stones. In this study, we evaluated a large series of patients' cohort treated at our institution, and assessed the causal effect of ESWL on the late occurrence of renal scar formation. ESWL was performed with EDAP (LT-01,02) that generates shock wave energy by piezoelectric discharge. We analyzed the records of 285 kidneys treated between Dec. 1986 and Nov. 1998. Renal scarring was noted in 44 kidneys and not in 241 kidneys with periodical ultrasonography. We compared the backgrounds of the two groups using chi-square or non-parametric analysis. The Kaplan-Meier method and Cox regression model determined the analysis of renal scar formation. Univariate and multiple regression analysis revealed that the total amount of ESWL emission and hyperuricemia independently affected the probability of renal scar formation. Over-emission of ESWL (over 10,000 shots) must be care for the prevention of renal scarring in patients with renal calyceal calculi, especially when associated with hyperuricemia. After ESWL, periodical checkups with ultrasonography will provide useful information for the clinical diagnosis of renal scarring.

    Full Text Available The mortality and morbidity from burns have diminished tremendously over the last six to seven decades. However, these do not truly reflect whether the victim could go back to society as a useful person or not and lead a normal life because of the inevitable post-burn scars, contractures and other deformities which collectively have aesthetic and functional considerations. This article gives an overview of the post-burn scars and scar contractures, especially their prevention, minimisation and principles of management.

    Full Text Available Orthodontic therapy apart from its benefits also has potential risks and limitations in terms of tissue damage. Fortunately, in orthodontics, risks are minimal and infrequent However, all potential risks and limitations should be considered and addressed when making the decision to undergo orthodontic treatment. Orthodontic treatment carries with it the risk of various types of soft and hard tissue damages (e.g. decalcification of enamel, lacerations, ulcerations, temporomandibular joint disorders, etc-, apart from treatment failure in itself. If correcting a malocclusion is to be of benefit, the advantages offered should outweigh any possible damage- All preventive procedures should be considered during and after orthodontic treatment to restore the normal health of soft and hard tissues. Hence, the orthodontist should be vigilant and prudent enough in assessing and monitoring every aspect of these tissues at any given stage and time in order to achieve a healthy and successful final result.

  10. Hypertrophic scars and keloids in surgery: current concepts.

    2014-09-01

    Hypertrophic scars and keloids remain a challenge in surgery. We appreciate that our understanding of the process at cellular and molecular level, profound as it is, when it comes to the clinical evidence much is left to be desired. Although the bench to bedside conundrum remains, the science of translational research calls for an even higher level of cooperation between the scientist and the clinician for the impetus to succeed.The clinicians alerted us to the possible theories in the pathogenesis of keloid formation, inter alia, the ischemia theory, mast cell theory, immune theory, transforming growth factor β interaction, mechanical theory, and the melanocyte stimulating hormone theory. All of the above presupposed a stimulus that would result in an uncontrolled upregulation of collagen and extracellular matrix expression in the pathogenesis of the keloid. This bedside to bench initiative, as in true science, realized more ponderables than possibilities.By the same token, research into the epidermal-mesenchymal signaling, molecular biology, genomics, and stem cell research holds much promise in the bench top arena. To assess efficacy, many scar assessment scores exist in the literature. The clinical measurement of scar maturity can aid in determining end points for therapeutics. Tissue oxygen tension and color assessment of scars by standardized photography proved to be useful.In surgery, the use of dermal substitutes holds some promise as we surmise that quality scars that arise from dermal elements, molecular and enzyme behavior, and balance. Although a systematic review shows some benefit for earlier closure and healing of wounds, no such review exists at this point in time for the use of dermal substitutes in scars.Adipose-derived stem cell, as it pertains to scars, will hopefully realize the potential of skin regeneration rather than by repair in which we are familiar with as well as the undesirable scarring as a result of healing through the inflammatory

    To assess the applicability of sequence characterized amplified region (SCAR) markers obtained from BOX, ERIC and RAPD fragments to design primers for real-time PCR quantification of the phytostimulatory maize inoculants Azospirillum brasilense UAP-154 and CFN-535 in the rhizosphere. Primers were designed based on strain-specific SCAR markers and were screened for successful amplification of target strain and absence of cross-reaction with other Azospirillum strains. The specificity of primers thus selected was verified under real-time PCR conditions using genomic DNA from strain collection and DNA from rhizosphere samples. The detection limit was 60 fg DNA with pure cultures and 4 x 10(3) (for UAP-154) and 4 x 10(4) CFU g(-1) (for CFN-535) in the maize rhizosphere. Inoculant quantification was effective from 10(4) to 10(8) CFU g(-1) soil. BOX-based SCAR markers were useful to find primers for strain-specific real-time PCR quantification of each A. brasilense inoculant in the maize rhizosphere. Effective root colonization is a prerequisite for successful Azospirillum phytostimulation, but cultivation-independent monitoring methods were lacking. The real-time PCR methods developed here will help understand the effect of environmental conditions on root colonization and phytostimulation by A. brasilense UAP-154 and CFN-535.

    Full Text Available Endometriosis that is defined as the presence of functional endometrial tissue outside the uterine cavity is seen 5-10% of reproductive age women. Endometriosis can be seen any other site of the body; but the most frequently affected areas are ovaries, pelvic peritoneum, uterosacral ligament and Douglas pouche. Several teories exist for the development of endometriosis including retrograde menstruation, venous or lymphatic metastasis and immun dysfunction. Endometriosis of the perineum and vulva are extremely rare with the most common sites being episiotomy scars. Scar endometriosis is likely to be caused by mechanical transplantation of endometrium from the uterine cavity into the wound at the time of the surgery. The primary treatment for scar endometriosis is total surgical excision of the lesion. It is important not to leave residual tissue during surgery to prevent the recurrence. Here we present a patient who had her vaginal delivery 5 years ago, have a complaint of painful vulvar lump at the right mediolateral episiotomy scar since 1 year during her every menstruation period and whose final diagnosis was endometriosis after surgical removal and histopathologic examination. Althought vulvar endometrosis is rare, it should be considered in the patients who had a vaginal delivery and complaining painful vulvar lump with swelling in her mestrual cycle.

    Deep facial burns leave conspicuous scar to the patients and affect their quality of life. Transparent facemask has been adopted for the prevention and treatment of facial hypertrophic scars for decades. Recently, with the advancement of 3D printing, the transparent facemask could facilitate the fitting of the facial contour. However, the effectiveness of the device and its biomechanical characteristics on pressure management of hypertrophic scar would need more objective evaluation. A biomechanical model of the transparent 3D-printed facemask was established through finite element analysis. Ten patients with extensive deep facial burns within 6 months were recruited for clinical study using 3D-printed facemask designed according to biomechanical model, and the interface pressure was measured on each patient. The patients in the treatment group (n=5) was provided with the 3D-printed transparent face mask soon after initial scar assessment, while the delayed treatment group (n=5) began the treatment one month after the initial scar assessment. The scar assessment was performed one month post intervention for both groups. The biomechanical modeling showed that the 3D, computer-generated facemask resulted in unbalanced pressure if design modifications were not incorporated to address these issues. The interface pressure between the facemask and patient's face was optimized through individualized design adjustments and the addition of silicone lining. After optimization of pressure through additional lining, the mean thickness and hardness of the scars of all 10 patients were decreased significantly after 1-month of intervention. In the delayed treatment group, the mean thickness of the scars was increased within the month without intervention, but it was also decreased after intervention. Facemask design and the silicone lining are important to ensure adequate compression pressure of 3D-printed transparent facemask. The intervention using the 3D-printed facemask

    Burn scars cause cosmetic disfigurement and psychosocial distress. We present two Fitzpatrick phototype (FP) III patients with burn scars successfully treated with combination pulsed dye laser (PDL) and non-ablative fractional lasers (NAFL). A 30-year-old, FP III woman with a history of a second-degree burn injury to the bilateral arms and legs affecting 30% body surface area (BSA) presented for cosmetic treatment. The patient received three treatments with 595 nm PDL (7 mm, 8 J, 6 ms), six with the 1550 nm erbium:glass laser (30 mJ, 14% density, 4-8 passes) and five with the 1927 nm thulium laser (10 mJ, 30% density, 4-8 passes). Treated burn scars improved significantly in thickness, texture and colour. A 33-year-old, FP III man with a history of a second-degree burn injury of the left neck and arm affecting 7% BSA presented for cosmetic treatment. The patient received two treatments with 595 nm PDL (5 mm, 7.5 J, 6 ms), four with the 1550 nm erbium:glass laser (30 mJ, 14% density, 4-8 passes) and two with the 1927 nm thulium laser (10 mJ, 30% density, 4-8 passes). The burn scars became thinner, smoother and more normal in pigmentation and appearance. Our patients' burn scars were treated with a combination of PDL and NAFL (two wavelengths). The PDL targets scar hypervascularity, the 1550 nm erbium:glass stimulates collagen remodelling and the 1927 nm thulium targets epidermal processes, particularly hyperpigmentation. This combination addresses scar thickness, texture and colour with a low side effect profile and is particularly advantageous in patients at higher risk of post-procedure hyperpigmentation. Our cases suggest the combination of 595nm PDL plus NAFL 1550 nm erbium:glass/1927 nm thulium device is effective and well-tolerated for burn scar treatment in skin of colour.

    2014-01-01

    "Pincushioning" is a complication of post-surgical scarring following use of transposition flaps particularly when surgery is performed on the nasal region. The transposition flap technique is very useful for the repair of certain defects of the tip of the nose, the medial canthus or of the ala nasi. The aim of this study is to define the clinical characteristics of this scarring dystrophy, which we propose to call "early hypertrophy scarring", to clarify the nature thereof and to assess the efficacy of intralesional injection of corticosteroids at the first signs of hypertrophy. A prospective, open, non-comparative, single-centre study examined the clinical and histological characteristics of early hypertrophy scarring and the effectiveness of therapy with one or two injections of corticosteroids performed on the 15th day post-operatively and optionally repeated at D45 depending on the outcome. From January 2011 to January 2013, 12 consecutive patients with early hypertrophy scarring were included (ten men and two women - mean age: 64 years). All had undergone surgery for basal cell carcinoma under local anaesthesia with one-stage repair by means of a rhombic flap or a bilobed flap located in the nasal area. Scars were injected strictly intra-lesionally with triamcinolone acetate (40 mg/1 mL) until whitening occurred. A single injection was performed in three cases of rhombic flap while a second injection was given at D45 in the remaining nine cases. Complete regression of the early hypertrophy scarring was obtained in ten of the 12 patients by D90. Incomplete regression was observed but with a marked improvement in the other two patients. Early hypertrophy scarring is distinguished by its clinical characteristics of hypertrophic or keloid scars. Biopsy performed in two cases showed the fibrous but non-fatty nature of early hypertrophy scarring. Biomechanical factors particular to the nasal region and the transposition flap technique could account for the early

    Surgical limb lengthening is undertaken to correct pathological short stature. Among the possible complications related to this procedure, painful and retractile scars are a cause for both functional and cosmetic concern. Our team has already shown the efficacy of autologous fat grafting in the treatment of scars with varying aetiology, so we decided to apply this technique to scars related to surgical correction of dwarfism. A prospective study was conducted to evaluate the efficacy of autologous fat grafting in the treatment of post-surgical scars in patients with short-limb dwarfism using durometer measurements and a modified patient and observer scar assessment scale (POSAS), to which was added a parameter to evaluate movement impairment. Between January 2009 and September 2012, 36 children (28 female and 8 male) who presented retractile and painful post-surgical scars came to our unit and were treated with autologous fat grafting. Preoperative and postoperative mean durometer measurements were analysed using the analysis of variance (ANOVA) test and POSAS parameters were studied using the Wilcoxon rank sum test. There was a statistically significant reduction in all durometer measurements (p-value treatment with autologous fat grafting. Surgical procedures to camouflage scars on lower limbs are not often used as a first approach and non-surgical treatments often lead to unsatisfactory results. In contrast, our autologous fat grafting technique in the treatment of post-surgical scars has been shown to be a valuable option in patients with short-limb dwarfism. There was a reduction of skin hardness and a clinical improvement of all POSAS parameters in all patients treated. Moreover, the newly introduced POSAS parameter appears to be reliable and we recommend that it is included to give a more complete evaluation of patient perception. Copyright © 2014 Elsevier Ltd.

    A caesarean section (CS) can cause a defect or disruption of the myometrium at the site of the uterine scar, called a niche. In recent years, an association between a niche and postmenstrual spotting after a CS has been demonstrated. Hysteroscopic resection of these niches is thought to reduce spotting and menstrual pain. However, there are no randomised trials assessing the effectiveness of a hysteroscopic niche resection. We planned a multicentre randomised trial comparing hysteroscopic niche resection to no intervention. We study women with postmenstrual spotting after a CS and a niche with a residual myometrium of at least 3 mm during sonohysterography. After informed consent is obtained, eligible women will be randomly allocated to hysteroscopic resection of the niche or expectant management for 6 months. The primary outcome is the number of days with postmenstrual spotting during one menstrual cycle 6 months after randomisation. Secondary outcomes are menstrual characteristics, menstruation related pain and experienced discomfort due to spotting or menstrual pain, quality of life, patient satisfaction, sexual function, urological symptoms, medical consultations, medication use, complications, lost productivity and medical costs. Measurements will be performed at baseline and at 3 and 6 months after randomisation. A cost-effectiveness analysis will be performed from a societal perspective at 6 months after randomisation. This trial will provide insight in the (cost)effectiveness of hysteroscopic resection of a niche versus expectant management in women who have postmenstrual spotting and a niche with sufficient residual myometrium to perform a hysteroscopic niche resection.

    Cutaneous leiomyosarcoma (CLM) is a very rare smooth muscle tumour that accounts for about 2-3% of all superficial soft tissue sarcomas. Although the development of various malignancies in scar tissue is well known, we report the first case of a CLM developing in a small pox scar. A 66-year-old man presented with a painless, slow-growing lump in a small pox scar on his left shoulder. Histological biopsies showed the lesion to be a primary, well-differentiated cutaneous leiomyosarcoma. A CT scan of the thorax was conducted, which showed no signs of metastases. The complete lesion was then surgically excised, and histopathological examination revealed a radically excised cutaneous type leiomyosarcoma After 13 months' review the patient was doing well with no evidence of tumour recurrence. This is the first report of a CLM arising in a small pox scar. Although the extended time interval between scarring and malignant changes makes it difficult to advise strict follow-up for patients with small pox scars, one should be aware that atypical changes and/or symptoms occurring in a small pox scar could potentially mean malignant transformation.

    Full Text Available Background and Objectives: Post-acne scarring is a common and well-known sequelae of acne vulgaris. We aim to study the impact of post-acne scarring on the quality of life (QOL among young adults in Singapore. Settings and Design: This was a non-interventional prospective study. Materials and Methods: Patients aged 21-40 years with atrophic and hypertrophic acne scars who attended the National Skin Centre, Singapore were recruited in the study. They answered a simple questionnaire and the clinical severity of their acne scars were assessed by the doctor. Statistical Analysis Used: Descriptive analyses using absolute and percentage frequencies were performed on all data. The test of significance was two-sided and was set at 5% (P ≤ 0.05. Differential analyses were conducted using the parametric, independent two-sample t-test and non-parametric Mann-Whitney U-test. The statistical assessments were performed using SPSS version 18.0. Results: A total of 100 patients were studied. The mean patients′ subjective self-scoring on the severity of their post-acne scars was 5.78/10 and the mean Dermatology Life Quality Index (DLQI for post-acne scars was 5.61. Many (36%, n = 36 were self-conscious of their acne scars and 24%, (n = 24 felt that their acne scars was affecting their social activities. Conclusions: Our study showed that post-acne scars have a significant negative effect on the QOL of young adults. It highlights the need to increase public awareness of acne vulgaris and its sequelae through education programs and advocating early treatment to reduce the risk of scarring.

    Current treatments for acne scars and enlarged facial pores have shown limited efficacy. To evaluate the efficacy and safety of the fractional photothermolysis system (FPS) with dynamic operating mode on acne scars and enlarged pores. Twelve patients with mild to moderate atrophic acne scars and enlarged pores were included in this study. Three sessions of FPS treatment were performed for acne scars and facial pores monthly. Two blinded dermatologists who compared before and after photos based on a quartile grading scale conducted objective clinical assessments of acne scar- and facial pore-treated areas. We took a biopsy immediately after one treatment with the laser from one of the authors to assess the histologic effects of the laser on facial pores. Follow-up results at 4 months after the last treatment revealed that, of the 12 patients, for acne scars, five demonstrated clinical improvements of 51% to 75% and three demonstrated improvements of 76% to 100%, and for facial pores, five demonstrated moderate clinical improvements of 26% to 50% and three demonstrated improvements of 76% to 100%. Side effects, including pain, post-treatment erythema, and edema, were resolved within 1 week. We suggest that the FPS may provide a new treatment algorithm in some cases with acne scars and enlarged pores. Considering the lack of placebo-controlled, split-face design of our study, optimized, prospective studies should be conducted to fully assess the efficacy of FPS with dynamic operating mode.

    Burn wounds are a global public health problem, which affects all countries, no matter the development stage and occurs in all age groups, from toddlers to elderly. In spite of burns being the cause of numerous household and work accidents, there are still no clear stated unanimous rules for their treatment. Every day new products appear on the market, each of them trying to prove more effective. Since ancient times, silver has been known for its antimicrobial properties, so it has been used for a long time in the treatment of burns and other types of wounds. One of the relatively modern methods of treatment is applying silver sheets on the scald lesions. In this paper, which was part of a larger study (research for a PhD thesis), concerning prevention and treatment of the post-burn pathological scars, the cases of some patients with burns, who were treated by using the above mentioned method were presented and analyzed. The results obtained by applying silver sheets were then commented and interpreted, pointing out the advantages and disadvantages compared to silver sulfadiazine creams and ointments, which have already been used at a large scale. The prevention and treatment of post-burn pathological (hypertrophic and keloid) scars is a field in which still little is known and in which there are also no clearly set therapy plans. We hope that through this research and the following ones we will manage to establish some major guidelines concerning the prevention of pathological scars, which are not only disabling, but also a major aesthetic issue for any patient, in order to obtain better outcomes.

    Son, Daegu; Harijan, Aram

    2014-06-01

    Management of incisional scar is intimately connected to stages of wound healing. The management of an elective surgery patient begins with a thorough informed consent process in which the patient is made aware of personal and clinical circumstances that cannot be modified, such as age, ethnicity, and previous history of hypertrophic scars. In scar prevention, the single most important modifiable factor is wound tension during the proliferative and remodeling phases, and this is determined by the choice of incision design. Traditional incisions most often follow relaxed skin tension lines, but no such lines exist in high surface tension areas. If such incisions are unavoidable, the patient must be informed of this ahead of time. The management of a surgical incision does not end when the sutures are removed. Surgical scar care should be continued for one year. Patient participation is paramount in obtaining the optimal outcome. Postoperative visits should screen for signs of scar hypertrophy and has a dual purpose of continued patient education and reinforcement of proper care. Early intervention is a key to control hyperplastic response. Hypertrophic scars that do not improve by 6 months are keloids and should be managed aggressively with intralesional steroid injections and alternate modalities.

    Full Text Available BACKGROUND. Split thickness skin graft harvesting causes a certain degree of scaring on the donor site. Donor site scar can cause aesthetic and functional sequelae on the patient's body. Our goal was to study the process of donor site selection, and then evaluate donor site scars and their impact on patients. PATIENTS AND METHODS. This retrospective study included 45 patients aged 5 to 61 years (in average 36, who have been treated with STSG in the 2004–2010 period. 57.8% of them were men. On a follow-up visit, we photographed healed skin defects and donor sites. We then determined and compared the surface areas of skin defect and the donor site using the Adobe® Illustrator® CS5 computer program. Donor site scars were assessed according to the Vancouver scar scale (VSS. We examined scar’s light touch sensitivity with monofilaments and skin colouring compared to adjacent healthy skin using colorimeter. Patients were also interviewed about their treatment course in a form of a standardized questionnaire. RESULTS. Our research has revealed that 20.0% of patients participated in the decision making process of choosing the donor site, while in 80.0% the donor site was chosen by the surgeon himself. 6.7% of patients were not satisfied with their donor site. Most of the patients (37/45 had donor sites on their thighs. In average, the donor site surface area was 94% bigger than the skin defect area. We found statistically significant differences in VSS values, light touch sensitivity and skin colouring between donor site scaring and adjacent healthy skin. CONCLUSIONS. Donor site scar can represent a lasting aesthetic and functional disability for patients. Our research has shown that most of the patients do not participate in the donor site selection process, but are satisfied with their donor site. In most cases, STGSs are harvested from the thigh, other anatomical regions, where scarring would be aesthetically less obtrusive, are underused

    Surgical, laser, and pharmacological therapies are all used to correct scars and surgical incisions, though have limits with respect to how well facial skin can be restored or enhanced. The use of cosmetics has long been a relevant adjunct to all scar treatment modalities. In recent years, technical advancements in the chemistry and composition of cosmetic products have provided the patient with a broader range of products to employ for concealing scars. This review will provide an overview of contemporary methods for concealing facial scars, birthmarks, and pigmentary changes without the use of traditional/dated, heavy appearing camouflage products. Additionally, general guidelines and information will be provided with respect to identifying competent makeup artists for care of the medical patient. The article by no means is meant to be a tutorial, but rather serves as a starting point in this allied field of medicine. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    The surgery and management of scars is a protracted and staged process that includes preparation of the skin through hygienic measures, scar softening (if indicated) with steroids, massage and pressure dressings, skilled execution of the surgical plan, and thorough postoperative wound care. This process generally covers a 1-year period for the various stages mentioned. Many general host and local skin factors will directly affect the final revision result. The two most important indirect factors that the surgeon must endeavor to control are optimal patient preparation and cutaneous health, and patient compliance with, and an ability to carry out, those wound care measures that the surgeon prescribes. Keloid and burn contracture scars represent two entities that are complicated and challenging to treat owing to their abnormal morphophysiologic features. Management of these scars is prolonged, and the patient must understand that the ultimate result will usually be a compromise. New grafting techniques, such as cultured autodermal grafts, offer improved initial management of burn wounds that may subsequently optimize scar revision in these patients. Keloids, and to a lesser extent hypertrophic scars, require steroid injections, pressure treatment, careful surgery, and protracted wound support and pressure treatment (exceeding 6 months) after surgery.

    Scarring is the consequence of surgery, trauma or different skin diseases. Apart from fresh, immature scars,that transform into mature scars over the course of would healing and that do not require further treatment,linear hypertrophic scars, widespread hypertrophic scars, keloids and atrophic scars exist. Symptoms like pruritusand pain, stigmatization as well as functional and aesthetic impairments that are very disturbing for the affected patients can bethe basis for the desire for treatment. Today, a multitude of options for the treatment and prevention of scars exists. Topical agents based on silicone or onion extract, intralesional injections of cristalline glucocorticoids (oftentimes in combinationwith cryotherapy) or 5-Fluorouracil as well as ablative and nonablative laser treatment are used. Current guidelines summarize the multitude of available treatment options and the currently available datafor the treating physicians, allowing them to make clear therapy recommendations for every single scar type. Relieving patients of their discomfort and doing their aesthetic demands justice is thus possible. Apart from scar prevention becoming more and more important, the increased use of modernlaser treatment options constitutes a key point in clinical scar treatment. At the same time the attention is turned to evaluating current therapeutic options with the help of contemporary study designs so as to graduallyimprove the level of evidence in scar treatment. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    We characterise and analyse the detachment (scar) surfaces of rockfalls to understand the mechanisms that underpin their failure. Rockfall scars are variously weathered and comprised of both discontinuity release surfaces and surfaces indicative of fracturing through zones of previously intact rock, known as rock bridges. The presence of rock bridges and pre-existing discontinuities is challenging to quantify due to the difficulty in determining discontinuity persistence below the surface of a rock slope. Rock bridges form an important control in holding blocks onto rockslopes, with their frequency, extent and location commonly modelled from the surface exposure of daylighting discontinuities. We explore an alternative approach to assessing their role, by characterising failure scars. We analyse a database of multiple rockfall scar surfaces detailing the areal extent, shape, and location of broken rock bridges and weathered surfaces. Terrestrial laser scanning and gigapixel imagery were combined to record the detailed texture and surface morphology. From this, scar surfaces were mapped via automated classification based on RGB pixel values. Our analysis of the resulting data from scars on the North Yorkshire coast (UK) indicates a wide variation in both weathering and rock bridge properties, controlled by lithology and associated rock mass structure. Importantly, the proportion of rock bridges in a rockfall failure surface does not increase with failure size. Rather larger failures display fracturing through multiple rock bridges, and in contrast smaller failures fracture occurs only through a single critical rock bridge. This holds implications for how failure mechanisms change with rockfall size and shape. Additionally, the location of rock bridges with respect to the geometry of an incipient rockfall is shown to determine failure mode. Weathering can occur both along discontinuity surfaces and previously broken rock bridges, indicating the sequential stages of

    Full Text Available To determine the incidence of renal scarring among patients with primary vesicoureteral reflux (VUR and the possible risk factor(s, we studied 90 children (60 girls and 30 boys with VUR followed in the Pediatric Nephrology Unit at the Ege University Hospital from 1998 to 2003. All the patients were assessed for VUR grade by voiding cystoureterography and for presence of renal scarring by (99 m technetium dimercapto-succinic acid scintigraphy. All infants with VUR were given low-dose prophylactic antibiotics and followed-up until resolution of the reflux. Grade of reflux and number of urinary tract infection (UTI episodes (≥3 were found to be statistically significant risk factors for renal scarring (P 0.05. Similarly, there was no statistically significant difference of frequency of renal scarring among the different age groups (P >0.05. We conclude that recurrences of UTI and VUR severity are significant risk factors for renal scarring in children with VUR. Therefore, identification of VUR at an early age may offer the opportunity to prevent episodes of UTI and possible formation of renal scars that may result in end-stage renal failure.

    While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. The aim of the present study is to assess the efficacy and safety of fractional CO2 laser resurfacing in atrophic facial acne scars. Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as 'excellent' if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar scars with minimal adverse effects.

    Scarring is the response elicited by the skin surface to injury and loss of tissue material. Wound healing takes place through a complex natural repair system consisting of vascular, inflammatory and proliferative phenomena, followed by a remodelling and cell apoptosis phase. This incredible repair system is inevitable, but sometimes unpredictable due to individual differences based on multiple factors. The scar is the objective criterion of a skin surgery, both for the patient and the dermsurgeon. It is therefore crucial to establish with the patient during the preoperative consultation, the size and positioning of the expected scar, taking into account the oncologic, anatomic and surgical constraints. Scars can ideally blend into normal skin, but may also give rise to various abnormalities. We can manage and prevent these abnormalities by mastering initial inflammation, that may induce hyperpigmentation and hypertrophy. Early massage using cortocosteroid topic or anti-inflammatory moisturizers may be effective. Random individual scarring may be minimized by a dynamic personalized accompanying scarring. © 2016 Elsevier Masson SAS. Tous droits réservés.

    The treatment of atrophic scars is difficult and dermal filler materials provide a simple alternative with immediate results. Esthélis® is an injectable non-animal crosslinked hyaluronic acid of Swiss origin characterized by a polydense cohesive matrix (CPM®) which produces a gel of uniform consistency with better biointegration to the tissues and a longer duration. To evaluate Esthélis in the treatment of atrophic scars. Twelve patients aged 18-56 years with facial atrophic scars caused by acne vulgaris, dog bite, piercing, basal cell carcinoma and leishmaniasis were treated with Esthélis. The injection technique was linear threading, serial puncture or a combination of both. Clinical efficacy was assessed independently by the authors and by patients immediately, one week and one month after the injection. Adverse events were registered. Authors described the results as moderate (27%), good (57%) and excellent (17%), immediately, one week and one month after the injection. Patients evaluated the cosmetic improvement as good (42%) or excellent (58%) one month after the treatment. Pain during the injection was described as slight or moderate. Only mild erythema was observed immediately after injection, which spontaneously resolved within few hours. Esthélis showed good or excellent results in most patients with atrophic scars, and these were perceived as even better when patients evaluated the cosmetic improvement. The best results were observed in patients with more deforming scars such as surgical scars or trauma.

    The term cesarean scar pregnancy refers to placental implantation within the scar of a previous cesarean delivery. The rising numbers of cesarean deliveries in the last decades have led to an increased incidence of cesarean scar pregnancy. Complications of cesarean scar pregnancy include morbidly adherent placenta, uterine rupture, severe hemorrhage, and preterm labor. It is suspected that cesarean scar pregnancies that are implanted within a dehiscent scar ("niche") behave differently compared with those implanted on top of a well-healed scar. To date there are no studies that have compared pregnancy outcomes between cesarean scar pregnancies implanted either "on the scar" or "in the niche." The purpose of this study was to determine the pregnancy outcome of cesarean scar pregnancy implanted either "on the scar" or "in the niche." This was a retrospective 2-center study of 17 patients with cesarean scar pregnancy that was diagnosed from 5-9 weeks gestation (median, 8 weeks). All cesarean scar pregnancies were categorized as either implanted or "on the scar" (group A) or "in the niche" (group B), based on their first-trimester transvaginal ultrasound examination. Clinical outcomes based on gestational age at delivery, mode of delivery, blood loss at delivery, neonate weight and placental histopathologic condition were compared between the groups with the use of the Mann-Whitney U test. Myometrial thickness overlying the placenta was compared among all the patients who required hysterectomy and those who did not with the use of the Mann-Whitney U test. Myometrial thickness was also correlated with gestational age at delivery with the use of Spearman's correlation. Group A consisted of 6 patients; group B consisted of 11 patients. Gestational age at delivery was lower in group B (median, 34 weeks; range, 20-36 weeks) than in group A (median, 38 weeks; range, 37-39 weeks; P=.001). In group A, 5 patients were delivered via cesarean delivery (with normal placenta), and

    The aim of the study was to assess the clinical outcomes of surgical repair of uterine cesarean scar defects with sonography (US). Seven nonpregnant women with history of cesarean section and a large uterine scar defect were enrolled. The surgical repair was performed by minilaparotomy. The US assessment of the uterine scar was performed using a standardized approach at baseline, then at a first visit 2-3 days following the surgical intervention (V1) and at a follow-up visit 3 months later (V2). Residual myometrial thickness (RMT), width, and depth of the scar defect were measured. The mean RMT increased significantly from 1.9 mm at baseline to 8.8 mm at V1 and 8.0 mm at V2. No intraoperative complications were observed. Postmenstrual spotting and abdominal pain reported preoperatively resolved after the operation. A surgical repair procedure for an incompletely healed uterine cesarean scar is effective in increasing RMT thickness, decreasing the depth of the scar, and reducing symptoms related to the cesarean section scar defect. Further studies on post-repair pregnancy outcomes are required to evaluate whether the procedure affects the rate of cesarean scar pregnancy, morbidly adherent placenta, and/or uterine scar dehiscence and rupture. The repair of a cesarean scar defect is recommended only for symptomatic women. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:455-460, 2017. © 2017 Wiley Periodicals, Inc.

    Different criteria to identify residual viability in chronically dysfunctioning myocardium in patients with coronary artery disease (CAD) can be derived by the combined assessment of myocardial blood flow (MBF) and glucose utilisation (MRG) using positron emission tomography (PET). The aim of this study was to evaluate, in a large number of patients, the prevalence of these different patterns by purely quantitative means. One hundred and sixteen consecutive patients with ischaemic cardiomyopathy (LVEF ≤40%) underwent resting 2D echocardiography to assess regional contractile function (16-segment model). PET with 15 O-labelled water (H 2 15 O) and 18 F-fluorodeoxyglucose (FDG) was used to quantify MBF and MRG during hyperinsulinaemic euglycaemic clamp. Dysfunctional segments with normal MBF (≥0.6 ml min -1 g -1 ) were classified as stunned, and segments with reduced MBF ( -1 g -1 ) as hibernating if MRG was ≥0.25 μmol min -1 g -1 . Segments with reduced MBF and MRG -1 g -1 were classified as transmural scars and segments with reduced MBF and MRG between 0.20 and 0.25 μmol min -1 g -1 as non-transmural scars. Eight hundred and thirty-four (46%) segments were dysfunctional. Of these, 601 (72%) were chronically stunned, with 368 (61%) having normal MRG (0.47±0.20 μmol min -1 g -1 ) and 233 (39%) reduced MRG (0.16±0.05 μmol min -1 g -1 ). Seventy-four (9%) segments with reduced MBF had preserved MRG (0.40±0.18 μmol min -1 g -1 ) and were classified as hibernating myocardium. In addition, 15% of segments were classified as transmural and 4% as non-transmural scar. The mean MBF was highest in stunned myocardium (0.95±0.32 ml min -1 g -1 ), intermediate in hibernating myocardium and non-transmural scars (0.47±0.09 ml min -1 g -1 and 0.48±0.08 ml min -1 g -1 , respectively), and lowest in transmural scars (0.40±0.14 ml min -1 g -1 , P -1 g -1 vs 0.46±0.20 μmol min -1 g -1 , NS), and lowest in stunned myocardium with reduced MRG and transmural scars

    Full Text Available Childhood adversity may lead to depressive relapse through its long-lasting influence on stress sensitivity. In line with the stress sensitization hypothesis, minor (daily stress is associated with depressive relapse. Therefore, we examine the impact of childhood adversity on daily stress and its predictive value on prospectively assessed depressive symptoms in recurrently depressed patients.Daily stress was assessed in recurrently depressed adult patients, enrolled into two randomized trials while remitted. The reported intensity and frequency of dependent and independent daily stress was assessed at baseline. Independent stress is externally generated, for example an accident happening to a friend, while dependent stress is internally generated, for example getting into a fight with a neighbor. Hierarchical regression analyses were performed with childhood adversity, independent and dependent daily stress as predictor variables of prospectively measured depressive symptoms after three months of follow-up (n = 138.We found that childhood adversity was not significantly associated with a higher frequency and intensity of daily stress. The intensity of both independent and dependent daily stress was predictive of depressive symptom levels at follow-up (unadjusted models respectively: B = 0.47, t = 2.05, p = 0.041, 95% CI = 0.02-0.92; B = 0.29, t = 2.20, p = 0.028, 95% CI = 0.03-0.55. No associations were found between childhood adversity and depressive symptoms at follow-up.No evidence was found supporting stress sensitization due to the experience of childhood adversity in this recurrently depressed but remitted patient group. Nevertheless, our research indicates that daily stress might be a target for preventive treatment.Trial A: Nederlands Trial Register NTR1907 Trial B: Nederlands Trial Register NTR2503.

    Full Text Available The formation of hypertrophic scars is common following healing of the burn wound, particularly in children. The face is one of the areas of the body most frequently affected by burns. Scar formation as a result of burn wounds leads to contraction of the formed granulation tissue, which causes both aesthetic and functional impairment for the patient. Scarring has major psychological and physical repercussions. Scarring on the face and visible regions of the body can be very distressing for the patient. Prevention of scars involves early and continuous use of a compressive orthesis. However, their efficacy is often limited to the facial region because of the contours of this area of body. This paper describes a clinical case of post-burn hypertrophic scars treated with silicone gel sheeting applied with pressure under custom made auto-polymerizing resin stent.

    To present a case of a late, deep stromal scar in a 22-year-old patient with forme fruste keratoconus who underwent combined corneal cross-linking and photorefractive keratectomy (PRK). Topography-guided corneal cross-linking combined with corneal PRK (without complications) was performed in both eyes with a delay of 2 weeks between each eye. At the 5-month postoperative examination of the right eye, a localized corneal haze was circumscribed to the posterior deep stroma, signifying a decrease of visual acuity. However, this improved partially and temporarily when treated with topical corticoids during 2 years of follow-up and then reoccurred, affecting the corrected distance visual acuity. To the authors' knowledge, this is the first documented, clinical case presenting a deep stromal affectation without endothelial decompensation and visual acuity affectation as a postoperative complication following topography-guided PRK and corneal cross-linking.

    Full Text Available Introduction: Acne scars are largely preventable complications of acne. 95% of the scars occur over the face thus impacting the quality of life. Correction of scars is the priority for acne patients. Materials and Methods: Thirty patients with post acne atrophic facial scars attending the OPD during the period from April to October 2013 were offered four sittings of microneedling with PRP on one side and microneedling with vitamin C on other side of the face at an interval of 1 month. Results: Twenty-seven out of the total 30 patients completed the treatment schedule. Two patients were lost to follow up and one dropped out of the study due to severe PIH. Mean age of the patients was 27.5 years. Out of 30 patients, 23 achieved reduction in scarring by one or two grades. Excellent response was seen in five (18.5% patients with platelet-rich plasma (PRP as compared to two (7% patients who received treatment with vitamin C according to physician′s assessment. As far as up gradation by 1 score is considered, i.e., good response, it was similar in both cases. Vitamin C did not prove to be as efficacious as PRP since 10 (37% patients had poor response in vitamin C-treated area compared to only 6 (22.2% patients who underwent PRP therapy, but vitamin C proved to be efficacious in dealing with post inflammatory hyper-pigmentation secondary to acne. Patients were more satisfied with PRP as compared to vitamin C. The results were evaluated and statistical analysis was done using SPSS 16.0.2. Conclusions: Overall results were better with microneedling and PRP. Vitamin C combined with microneedling also showed improvement with respect to firmness and smoothness of skin; as well as post inflammatory hyper-pigmentation. Microneedling combined with PRP proved to be good in treating boxcar and rolling scars but had limited efficacy in dealing with ice pick scars.

    To compare breath-hold (BH) with navigated free-breathing (FB) 3D late gadolinium enhancement cardiac MRI (LGE-CMR) MATERIALS AND METHODS: Fifty-one patients were retrospectively included (34 ischaemic cardiomyopathy, 14 non-ischaemic cardiomyopathy, three discarded). BH and FB 3D phase sensitive inversion recovery sequences were performed at 3T. FB datasets were reformatted into normal resolution (FB-NR, 1.46x1.46x10mm) and high resolution (FB-HR, isotropic 0.91-mm voxels). Scar mass, scar edge sharpness (SES), SNR and CNR were compared using paired-samples t-test, Pearson correlation and Bland-Altman analysis. Scar mass was similar in BH and FB-NR (mean ± SD: 15.5±18.0 g vs. 15.5±16.9 g, p=0.997), with good correlation (r=0.953), and no bias (mean difference ± SD: 0.00±5.47 g). FB-NR significantly overestimated scar mass compared with FB-HR (15.5±16.9 g vs 14.4±15.6 g; p=0.007). FB-NR and FB-HR correlated well (r=0.988), but Bland-Altman demonstrated systematic bias (1.15±2.84 g). SES was similar in BH and FB-NR (p=0.947), but significantly higher in FB-HR than FB-NR (pFB-NR (pFB-HR than FB-NR (p<0.01). Navigated free-breathing 3D LGE-CMR allows reliable scar mass quantification comparable to breath-hold. During free-breathing, spatial resolution can be increased resulting in improved sharpness and reduced scar mass. • Navigated free-breathing 3D late gadolinium enhancement is reliable for myocardial scar quantification. • High-resolution 3D late gadolinium enhancement increases scar sharpness • Ischaemic and non-ischaemic cardiomyopathy patients can be imaged using free-breathing LGE CMR.

    This study assessed the regenerative efficacy of basic fibroblast growth factor (FGF) in a rabbit model of chronic vocal fold scarring and then confirmed its utility and safety in a prospective trial of patients with this condition. FGF was injected three times, at 1-week intervals, into a chronic vocal fold scar created in a rabbit model. After 1 month, mRNA level of procollagen I, hyaluronic acid synthetase 2 (HAS 2), and matrix metalloproteinase 2 (MMP 2) were analyzed by real-time polymerase chain reaction. The relative densities of hyaluronic acid (HA) and collagen were examined 3 months post-injection. From April 2012 to September 2014, a prospective clinical trial was conducted at a tertiary hospital in Korea. FGF was injected into the mild vocal fold scar of 17 consecutive patients with a small glottic gap. The patients underwent perceptual, stroboscopic, acoustic aerodynamic test, and Voice Handicap Index (VHI) survey prior to and 3, 6, and 12 months after FGF injection. FGF injection of the vocal fold scar decreased the density of collagen and increased mRNA level of HAS 2 and MMP 2 expression significantly compared to the control group injected with phosphate buffered solution in a rabbit model (Pvocal fold injections of FGF in patients with mild chronic vocal fold scarring can significantly improve voice quality for as long as 1 year and without side effects. Our results recommend the use of FGF vocal fold injection as an alternative treatment modality for mild chronic vocal fold scarring.

    Acne scars can be improved with various treatments such as topical creams, chemical peels, dermal fillers, microdermabrasion, laser, and radiofrequency devices. Some of these treatments especially lasers and deep chemical peels can have significant side effects such as post inflammatory hyperpigmentation in darker skin types. Fraxelated RF Laser devices have been reported to have lower incidence of side effects in all skin phototypes. Nine patients between ages 18 and 35 of various skin phototypes were selected from a private practice and treated with a RF fraxelated device (E-matrix) for acne scars. Outcomes were measured by physician observation, subjective feedback received by patients, and comparison of before and after photographs. In this small group of patients with various skin phototypes, fraxelated radiofrequency device improved acne scars with minimal side effects and downtime.

    Facial scaring is considered one of the most difficult cosmetic problems for any plastic surgeon to solve. The condition is more difficult if the direction of the scar is not parallel to relaxed skin tension lines. Attempts to manage this difficult situation included revisions using geometric designs, Z plasties or W plasties to camouflage the straight line visible scaring. The use of long-lasting resorbable sutures was tried too. Recently, the use of botulinum toxin during revision improved the results. Fractional CO2 lasers, microfat grafts, and platelet-rich plasma were added to the armamentarium. The scar is least visible if placed in the junction between the facial subunits. The aim of this study is to investigate the use of the subunit principle to improve the results of scar revision. Four patients were included in this study. Tissue expansion of the intact part of the subunit allowed shifting the scar to the junction between the affected subunit and the adjacent one. Tissue expansion, delivery of the expanders, and advancement of the flaps were successful in all patients. The fact that this is a 2-stage procedure and sacrifices some of the intact skin from the affected facial subunit, makes this technique reserved to patients with ugly facial scars who are ambitious to improve their appearance.

    2017-04-01

    BACKGROUND: Atrophic scarring in skin of color is a common, permanent, and distressing result of uncontrolled acne vulgaris. Ablative lasers and chemical peels are frequently used to improve the appearance of atrophic scars, primarily through the stimulation of collagen and elastin; however, these treatment modalities are associated with risks, such as dyspigmentation and hypertrophic scarring, especially in patients with darker skin. OBJECTIVE: We evaluated the efficacy of topically applied synthetic epidermal growth factor (EGF) serum in reducing the appearance of atrophic acne scars in skin of color. METHODS: A single-center clinical trial was performed on twelve healthy men and women (average age 32.5) with Fitzpatrick Type IV-V skin and evidence of facial grade II-IV atrophic acne scars. Subjects applied topical EGF serum to the full-face twice daily for 12 weeks. Scar improvement was investigated at each visit using an Investigator Global Assessment (IGA), a Goodman grade, clinical photography, and patient self-assessment. RESULTS: Eleven subjects completed the trial. Compared to baseline, there was an improvement in mean IGA score from 3.36 (SEM = 0.15) to 2.18 (SEM = 0.33). Mean Goodman grade was reduced from 2.73 (SEM = 0.19) to 2.55 (SEM = 0.21). Of the eleven pairs of before and after photographs, nine were correctly chosen as the post-treatment image by a blind investigator. On self-assessment, 81% reported a "good" to "excellent" improvement in their scars compared to baseline (P = 0.004). CONCLUSION: Topical EGF may improve the appearance of atrophic acne scars in skin of color. Additional, larger studies should be conducted to better characterize improvement.

    Full Text Available Abnormally pigmented scars are an undesirable consequence of cutaneous wound healing and are a complication every single individual worldwide is at risk of. They present a challenge for clinicians, as there are currently no definitive treatment options available, and render scars much more noticeable making them highly distressing for patients. Despite extensive research into both wound healing and the pigment cell, there remains a scarcity of knowledge surrounding the repigmentation of cutaneous scars. Pigment production is complex and under the control of many extrinsic and intrinsic factors and patterns of scar repigmentation are unpredictable. This article gives an overview of human skin pigmentation, repigmentation following wounding and current treatment options.

    Objective : Objective measure of scarring and three-dimensional (3D) facial asymmetry after surgical correction of unilateral cleft lip (UCL) and unilateral cleft lip (UCLP). It was hypothesized that the degree of scarring or asymmetry would be correlated with poorer psychological function. Design : In a cross-sectional design, children underwent 3D imaging of the face and completed standardized assessments of self-esteem, depression, and state and trait anxiety. Parents rated children's adjustment with a standard scale. Setting : Glasgow Dental School, School of Medicine, College of Medical, Veterinary and Life Sciences. Patients : Fifty-one children aged 10 years with UCLP and 43 with UCL were recruited from the cohort treated with the surgical protocol of the CLEFTSIS managed clinical network in Scotland. Methods : Objective assessment to determine the luminance and redness of the scar and facial asymmetry. Depression, anxiety, and a self-esteem assessment battery were used for the psychological analysis. Results : Cleft cases showed superior psychological adjustment when compared with normative data. Prevalence of depression matched the population norm. The visibility of the scar (luminance ratio) was significantly correlated with lower self-esteem and higher trait anxiety in UCLP children (P  =  .004). Similar but nonsignificant trends were seen in the UCL group. Parental ratings of poorer adjustment also correlated with greater luminance of the scar. Conclusions : The objectively defined degree of postoperative cleft scarring was associated with subclinical symptoms of anxiety, depression, and low self-esteem.

    Full Text Available Seven (7 cases of depressed facial scars which included depressed distensile acne scars, depressed bound down scars of acne excluding deep ice pick scars, and scars of varicella constituted the study group. The scars were treated with a new method named subcuticular undermining. A tri-bevelled hypodermic needle was inserted through a puncture in the skin surface and its sharp edges were manouevered under the scar. The depression was lifted by the releasing action of the needle maneuevere and from connective tissue that forms in course of normal wound healing. Approximately 50% to 80% improvement of all the scars were noticed. Patient’s compliance was highly satisfactory. Subcision is an appropriate, option in depressed scars of black skin (Type IV-Type VI where dermabrasion and medium-depth and deep chemical peeling are contraindicated.

    Many therapies involving varying degrees of complexity have been used to treat acne scars, but none is considered the gold standard treatment. A comparative evaluation of 88% phenol and 90% trichloroacetic acid (TCA) applied using the chemical reconstruction of skin scars (CROSS) technique. A nonrandomized, single-blinded self-controlled clinical trial was conducted among patients with ice pick-type and boxcar-type atrophic acne scars. Using 88% phenol on the left hemiface and 90% TCA on the right hemiface was adopted as the standard practice of the CROSS technique. The dermatological quality of life index (DLQI) questionnaire, acne scar grading scale Échelle d´Evaluation Clinique des Cicatrices d'Acne (ECCA), and evaluation of improvement were performed pretreatment and post-treatment. Regarding ECCA, significant differences were found in pretreatment and post-treatment (p < .001). Regarding tolerance to pain, it was found that the discomfort felt with 90% TCA was significantly less than that felt with 88% phenol (p = .020). Regarding the quality of life measured with the DLQI, the results showed that the mean score in post-treatment assessment was significantly lower than that in the pretreatment assessment (p < .05). Hypochromia and enlargement scar were only seen after the use of 90% TCA. This study confirmed the efficacy of both TCA and phenol for treating such scars, with less severe complications from the use of phenol.

    Full Text Available Background: Treatment of acne scars with ablative fractional laser resurfacing has given good improvement. But, data on Indian skin are limited. A study comparing qualitative, quantitative, and subjective assessments is also lacking. Aim: Our aim was to assess the improvement of facial acne scars with Erbium-doped Yttrium Aluminium Garnet (Er:YAG 2940 nm fractional laser resurfacing and its adverse effects in 25 patients at a tertiary care teaching hospital. Methods: All 25 patients received four treatment sessions with Er:YAG fractional laser at 1-month interval. The laser parameters were kept constant for each of the four sittings in all patients. Qualitative and quantitative assessments were done using Goodman and Barron grading. Subjective assessment in percentage of improvement was also documented 1 month after each session. Photographs were taken before each treatment session and 1 month after the final session. Two unbiased dermatologists performed independent clinical assessments by comparing the photographs. The kappa statistics was used to monitor the agreement between the dermatologists and patients. Results: Most patients (96% showed atleast fair improvement. Rolling and superficial box scars showed higher significant improvement when compared with ice pick and deep box scars. Patient′s satisfaction of improvement was higher when compared to physician′s observations. No serious adverse effects were noted with exacerbation of acne lesions forming the majority. Conclusion: Ablative fractional photothermolysis is both effective and safe treatment for atrophic acne scars in Indian skin.Precise evaluation of acne scar treatment can be done by taking consistent digital photographs.

    Full Text Available INTRODUCTION Renal scarring is the most common cause of arterial hypertension in children. High blood pressure (BP and microalbuminuria contribute to the progression of chronic renal disease. OBJECTIVE The aims of the study were: to assess BP in children with renal scarring by continuous ambulatory blood pressure measurement (ABPM in comparison to the casual method (CBP, and to determine the correlation between ambulatory blood pressure (ABP and/or casual blood pressure (CBP values and proteinuria in children with renal scarring. METHOD This forward-looking study comprised thirty-five children (26 girls and 9 boys, aged between 3-13 years, 10.4±3.9, X+SD. Blood pressure was measured using the casual method (CBP with a mercury manometer; BP was measured three times and the average was taken as a referent value. ABPM was performed using the oscillometric method with the Space Labs device, model 90207. RESULTS 45.71% of patients were classified as hypertensive by ABPM, while only 22.6% of CBP measurements were above the 95th percentile (p<0.01. "White coat hypertension" was present in 40% of the patients. Non-dipping BP alteration was detected in 37.14% of the patients. CONCLUSION Nocturnal systolic hypertension (systolic non-dipping alteration is very frequent in children with renal scarring. Nocturnal diastolic blood pressure, detectable only via ABPM, is positively correlated with proteinuria and may be an initial sign of the progression of renal scarring. ABPM is more sensitive than CBP in the evaluation of BP in children with renal scarring.

    Full Text Available PURPOSE: To assess the value of intravenous urography (IVU in detecting and grading the renal scar, comparing its results with those of scintigraphy with dimercaptosuccinic acid (DMSA. MATERIALS AND METHODS: The study included 43 children investigated by DMSA and IVU, who had vesicoureteral reflux diagnosed and classified through voiding cystourethrography. RESULTS: Among the kidneys with reflux, there was agreement between the results of DMSA and IVU concerning the presence and the absence of scars in 82.4% of the cases. Based on the results obtained, IVU would have a sensitivity of 66.6%, specificity of 94.4%; accuracy of 82.5%; positive predictive value (PPV of 90% and negative predictive value (NPV of 79%, when compared with DMSA results. Our data also confirm the close relation between the reflux grade and the presence of renal scar, since 75% of the kidneys with grade IV and V reflux presented scars. In relation to the grading of nephropathy, in 78% of patients the classification of the scar by both methods was identical. The highest disagreement was verified in the group with segmental scar on DMSA, where 41.6% of the kidneys were classified as normal on IVU. CONCLUSION: The data obtained confirm that the scintigraphy with DMSA is essential in the investigation of patients with renal scar, and cannot be replaced by IVU, due to its low sensitivity and lower ability of satisfactory grading.

    Facial burns could create serious scar problems resulting disfigurement particularly on children. The conventional methods of producing transparent face masks for scar control remains complex and require dexterous skills of experienced clinician and patients' compliance during fitting. In this study, we adopted a portable 3D scanning and Computer-Aided Design (CAD) to produce 3D-printed transparent facemasks. Its efficacy was tested on two children with facial burns resulting hypertrophic scars. This study adopted a longitudinal case follow up research design. Two children with facial burns were recruited in the study upon consent. Their facial features were scanned with a portable 3D scanner and then edited and converted to the target files: the customized printable facemask files. The transparent facemask was directly printed out on the transparent biocompatible material followed by adding the medical grade silicone gel to provide extra pressure on the scar site. The facemasks were fitted to the patients with elastic straps connecting the printed anchoring bolts. Both children and family were instructed to wear the facemask for at least 20h per day and they were assessed before treatment, one month and three months after treatment on the facial scar conditions. At the one-month and three-month assessments after treatment, a decrease in average scar thickness was shown and the facial appearance was satisfactory. The 3D-printed facemasks were well fitted on both patients. The treatment was well-tolerated and no complication was reported. 3D-printed transparent facemask is convenient and efficient to fabricate, and is suitable for treating pediatric facial hypertrophic scars after burn.

    Objective: To compare the use of intralesional triamcinolone acetonide and its combination with 5 flourouracil in the treatment of keloid and hypertrophic scars in terms of reduction in initial height of the scar. Methods: The randomised controlled trial was conducted at the Department of Plastic Surgery, King Edward Medical University, Lahore, from March 2011 to December 2012. It comprised patients of both genders having keloids or hypertrophic scars (1 cm to 5 cm in size) having no history of treatment for the scars in preceding 6 months. Those who were pregnant, planning pregnancy or lactating were excluded. The subjects were divided into two groups: Group A received intralesional triamcinolone acetonide alone; and Group B received triamcinolone acetonide + 5 flourouracil. Eight injections were given at weekly interval. Scars were assessed 4 weeks after the completion of treatment on a five-point scale. SPSS 16 was used for statistical analysis. Results: The 150 subjects in the study were divided into two equal groups of 75(50%) each. Good to excellent results were seen in 51(68%) cases in Group A compared to 63(84%) in Group B. Frequency of complications was 18(24%) and 6(8%) in Group A and Group B respectively. Conclusion: Combination of triamcinolone acetonide and 5 flourouracil is superior to triamcinolone acetonide therapy in the treatment of keloids and hypertrophic scars. (author)

    Fractional technology overcomes the problems of ablative lasers, such as inaccurate depth control and damage to the epidermis. Minimally invasive fractional radiofrequency microneedle devices allow for more-selective heating of the dermis. To evaluate the clinical efficacy of fractional radiofrequency microneedle (ERM) treatment in acne scars and large facial pores. Thirty patients with acne scars and large facial pores were enrolled. Bipolar radiofrequency energy was delivered to the skin through the electrodes of the FRM device. Skin lesions were evaluated according to grade of acne scars, Investigator Global Assessment of large pores, skin surface roughness, transepidermal water loss (TEWL), dermal density, microscopic and composite image, sebum measurement, and questionnaires regarding patient satisfaction. The grade of acne scars and Investigator Global Assessment of large pores improved in more than 70% of all patients. Skin surface roughness, dermal density, and microscopic and composite images also improved, whereas TEWL and sebum measurement did not change. Clinical improvement from FRM treatment appeared to be related to dermal matrix regeneration. FRM treatment may be effective in improving acne scars and facial pores. © 2012 by the American Society for Dermatologic Surgery, Inc. Published by Wiley Periodicals, Inc.

    Ablative fractional resurfacing (AFR) is a new modality for photorejuvenation and acne scars which combines carbon dioxide (CO₂) laser ablation with fractional photothermolysis. The objective is to evaluate the efficacy and side effects of a new fractional CO₂ ablative device (Fraxel Re:pair) for skin rejuvenation and acne scars in Asians. Nine patients underwent one full-face treatment. The energy levels ranged from 30-70 mJ with coverage between 30% and 45%. Improvement in skin texture, laxity, wrinkles, enlarged pores, overall pigmentation irregularity, and adverse effects were assessed up to 6 months post-treatment. Standardized photographs using the Canfield Visia CR system® were assessed by two independent observers. Subjective improvement was assessed by patient questionnaires. Nine Chinese patients (skin types III and IV, mean age 44.8) were included. Statistically significant improvements were seen for skin texture, skin laxity, wrinkles, enlarged pores, and acne scars. The post-inflammatory hyperpigmentation rate was 55.5% and 11.1% at 1 and 6 months post-treatment, respectively. Eighty-six percent of patients were overall satisfied to very satisfied with the treatment. Ablative fractional CO₂ laser resurfacing was overall safe and effective for skin rejuvenation and acne scars in Asians. However, in view of the high post-inflammatory rate and the statistically significant but only mild to moderate improvement after a single treatment as observed in this study, there is a need to review the current role of fractional ablative CO₂ laser treatment as compared to fractional non-ablative for skin rejuvenation and acne scar treatment in Asians. © 2010 Wiley-Liss, Inc.

    Hypertrophic scarring is a major postoperative complication which leads to severe disfigurement and dysfunction in patients and usually requires multiple surgical revisions due to its high recurrence rates. Excessive-mechanical-loading across wounds is an important initiator of hypertrophic scarring formation. In this study, we demonstrate that intradermal administration of a single extracellular matrix (ECM) molecule-fibromodulin (FMOD) protein-can significantly reduce scar size, increase tensile strength, and improve dermal collagen architecture organization in the normal and even excessive-mechanical-loading red Duroc pig wound models. Since pig skin is recognized by the Food and Drug Administration as the closest animal equivalent to human skin, and because red Duroc pigs show scarring that closely resembles human proliferative scarring and hypertrophic scarring, FMOD-based technologies hold high translational potential and applicability to human patients suffering from scarring-especially hypertrophic scarring. © 2018 The Authors.

    The application of laser treatments beginning on the day of stitch removal has been demonstrated to improve scar quality. However, there are few guidelines for the treatment of immature scars (ISs), which are defined as "scars whose features are not yet expressed." The purpose of this study was to extract information about early combination laser treatment (CLT) beyond what is currently known by analyzing 33 pairs of pre-treatment and post-treatment photographs of ISs. Two hundred fifty medical records of patients with scars were reviewed, and 33 scars were included in the study. The included scars were treated with vascular lasers (585 or 532 nm) followed by 1550-nm fractional lasers from May 2014 to July 2015 (fewer than 52 days after stitch removal, Fitzpatrick's skin types III-IV, mean age = 16.0 years). Blinded evaluators (one plastic surgeon and two dermatologists) evaluated the pre-treatment and post-treatment photographs. The pre-treatment photographs were scored on a spectrum from "0," when no difference with the surrounding unaffected skin was observed, to "100," when the worst scarring was present. The pre-treatment and post-treatment photographs were compared, and the results were graded on a spectrum from 0, when no difference between the pre-treatment and post-treatment photographs was observed, to 100, when no difference was observed between the post-treatment skin and the surrounding unaffected skin. Statistical analyses were performed with PASW 17.0, SPSS Korea, Seoul, Korea (p laser groups. Patient age and Wtd score were negatively correlated, and a significant difference was observed in the Wtd scores between the age groups (≥15 and lasers are equally effective for CLT of ISs.

    Full Text Available Abstract Background Late gadolinium enhancement (LGE cardiovascular magnetic resonance (CMR enables state-of-the-art in vivo evaluations of myocardial fibrosis. Although LGE patterns have been well described in asymmetrical septal hypertrophy, conflicting results have been reported regarding the characteristics of LGE in apical hypertrophic cardiomyopathy (ApHCM. This study was undertaken to determine 1 the frequency and distribution of LGE and 2 its prognostic implication in ApHCM. Methods Forty patients with asymptomatic or minimally symptomatic pure ApHCM (age, 60.2 ± 10.4 years, 31 men were prospectively enrolled. LGE images were acquired using the inversion recovery segmented spoiled-gradient echo and phase-sensitive inversion recovery sequence, and analyzed using a 17-segment model. Summing the planimetered LGE areas in all short axis slices yielded the total volume of late enhancement, which was subsequently presented as a proportion of total LV myocardium (% LGE. Results Mean maximal apical wall thickness was 17.9±2.3mm, and mean left ventricular (LV ejection fraction was 67.7 ± 8.0%. All but one patient presented with electrocardiographic negative T wave inversion in anterolateral leads, with a mean maximum negative T wave of 7.2 ± 4.7mm. Nine patients (22.5% had giant negative T waves, defined as the amplitude of ≥10mm, in electrocardiogram. LGE was detected in 130 segments of 30 patients (75.0%, occupying 4.9 ± 5.5% of LV myocardium. LGE was mainly detected at the junction between left and right ventricles in 12 (30% and at the apex in 28 (70%, although LGE-positive areas were widely distributed, and not limited to the apex. Focal LGE at the non-hypertrophic LV segments was found in some ApHCM patients, even without LGE of hypertrophied apical segments. Over the 2-year follow-up, there was no one achieving the study end-point, defined as all-cause death, sudden cardiac death and hospitalization for heart failure

    The hypertrophic scar is a medical difficulty of humans, which has caused great pain to patients. Here, we investigated the inhibitory effect of miR-29b on scar formation. The scalded model was established in mice and miR-29b mimics or a negative control was subcutaneously injected into the injury skin. Then various molecular biological experiments were performed to assess the effect of miR-29b on scar formation. According to our present study, first, the results demonstrated that miR-29b was down-regulated in thermal injury tissue and miR-29b treatment could promote wound healing, inhibit scar formation, and alleviate histopathological morphologic alteration in scald tissues. Additionally, miR-29b treatment suppressed collagen deposition and fibrotic gene expression in scar tissues. Finally, we found that miR-29b treatment inhibited the TGF-β1/Smad/CTGF signaling pathway. Taken together, our data suggest that miR-29b treatment has an inhibitory effect against scar formation via inhibition of the TGF-β1/Smad/CTGF signaling pathway and may provide a potential molecular basis for future treatments for hypertrophic scars.

    Although pressure therapy (PT) has been widely used as the first-line treatment for hypertrophic scars (HS), the histopathological changes involved have seldom been studied. This study aimed to examine the longitudinal effect of PT on the histopathological changes in HS. Ten scar samples were selected from six patients with HS after burn and they were given a standardized PT intervention for 3 months while 16 scar samples were obtained on those without PT. The scar biopsies were collected pre-treatment, 1 and 3 months post-intervention for both clinical and histopathological examinations. Clinical assessments demonstrated significant improvement in the thickness and redness of the scars after PT. Histological examination revealed that cell density in the dermal layer was markedly reduced in the 3-months post-pressurized scar tissues, while the arrangement of the collagen fiber was changed from nodular to wave-like pattern. The α-smooth muscle actin immunoreactivity was significantly decreased after 1-month pressure treatment. There was a significant reduction of myofibroblasts population and a concomitant increase in the apoptotic index in the dermal layer in the 3-months' post-pressurized scars. A significant negative correlation was found between the myofibroblasts population and the apoptotic index. The keratinocyte proliferation was found inhibited after PT. Results demonstrated that PT appeared to promote HS maturation by inhibiting the keratinocyte proliferation and suppressing myofibroblasts population, the latter possibly via apoptosis.

    Scars represent the visible sequelae of trauma, injury, burn, or surgery. They may induce distress in the patient because of their aesthetically unpleasant appearance, especially if they are excessively raised, depressed, wide, or erythematous. They may also cause the patient symptoms of pain, tightness, and pruritus. Numerous products are marketed for scar prevention or improvement, but their efficacy is unclear. A literature review of high-level studies analyzing methods to prevent or improve hypertrophic scars, keloids, and striae distensae was performed. The evidence from these articles was analyzed to generate recommendations. Each intervention's effectiveness at preventing or reducing scars was rated as none, low, or high, depending on the strength of the evidence for that intervention. For the prevention of hypertrophic scars, silicone, tension reduction, and wound edge eversion seem to have high efficacy, whereas onion extract, pulsed-dye laser, pressure garments, and scar massage have low efficacy. For the treatment of existing hypertrophic scars, silicone, pulsed-dye laser, CO2 laser, corticosteroids, 5-fluorouracil, bleomycin, and scar massage have high efficacy, whereas onion extract and fat grafting seem to have low efficacy. For keloid scars, effective adjuncts to excision include corticosteroids, mitomycin C, bleomycin, and radiation therapy. No intervention seems to have significant efficacy in the prevention or treatment of striae distensae. Although scars can never be completely eliminated in an adult, this article presents the most commonly used, evidence-based methods to improve the quality and symptoms of hypertrophic scars, as well as keloid scars and striae distensae.

    The relationship between myocardial viability and angiographic collateral flow is not fully elucidated in ischemic cardiomyopathy (ICM) with coronary artery chronic total occlusion (CTO). We aimed to clarify the relationship between myocardial hibernation, myocardial scar, and angiographic collateral flow in these patients. Seventy-one consecutive ICM patients with 122 CTOs and 652 dysfunctional segments within CTO territories were retrospectively analyzed. Myocardial hibernation (perfusion-metabolism mismatch) and the extent of 18 F-fluorodeoxyglucose (FDG) abnormalities were assessed using 99m Tc-sestamibi and 18 F-FDG imaging. Myocardial scar was evaluated by late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) imaging. Collateral flow observed on coronary angiography was assessed using Rentrop classification. In these patients, neither the extent nor frequency of myocardial hibernation or scar was related to the status of collateral flow. Moreover, the matching rate in determining myocardial viability was poor between any 2 imaging indices. The extent of 18 F-FDG abnormalities was linearly related to the extent of LGE rather than myocardial hibernation. Of note, nearly one-third (30.4%) of segments with transmural scar still had hibernating tissue. Hibernation and non-transmural scar had higher sensitivity (63.0% and 66.7%) than collateral flow (37.0%) in predicting global functional improvement. Angiographic collateral cannot accurately predict myocardial viability, and has lower sensitivity in prediction of functional improvement in CTO territories in ICM patients. Hence, assessment of myocardial viability with non-invasive imaging modalities is of importance. Moreover, due to the lack of correlation between myocardial hibernation and scar, these two indices are complementary but not interchangeable.

    This study aimed to evaluate columellar scar problems after external rhinoplasty in the Arabian population, and to analyze the technical factors that help prevent such problems and maximize the scar cosmesis. The investigation was conducted in university and private practice settings of the author in Alexandria, Egypt. A total of 600 Arab patients who underwent external rhinoplasty were included in the study. All the patients underwent surgery using the external rhinoplasty approach, in which bilateral alar marginal incisions were connected by an inverted V-shaped transcolumellar incision. At completion of the procedure, a two-layer closure of the columellar incision was performed. At a minimum of 1 year postoperatively, the columellar scar was evaluated subjectively by means of a patient questionnaire, and objectively by clinical examination and comparison of the close-up pre- and postoperative basal view photographs. Objectively, anything less than a barely visible, leveled, thin, linear scar was considered unsatisfactory. Subjectively, 95.5% of the patients rated the scar as unnoticeable, 3% as noticeable but acceptable, and 1.5% as unacceptable. Objectively, the scar was unsatisfactory in 7% of the cases. This was because of scar widening with or without depression (5%), hyperpigmentation (1.5%), and columellar rim notching (0.5%). The use of a deep 6/0 polydioxanon (PDS) suture significantly decreased the incidence of scar widening (p < 0.005).The columellar incision can be used safely in the Arab population regardless of their thick, dark, and oily skin. Technical factors that contributed to the favorable outcome of the columellar scar included proper planning of location and design of the incision used, precise execution, meticulous multilayered closure, and good postoperative care.

    Burns and chronic inflammation are well-known circumstances in which malignant transformation may occur during wound healing. There are many reports of malignancies developing from a burn scar; however, there are only a few reports of malignancy arising from chronic inflammation or from the skin of a surgical scar following excision of a benign mass, in any part of the body. There are only twelve reported cases of breast cancer developing from a surgical scar, moreover, there have been no reports in the last 30 years. This case is a recent example of breast cancer developing in a surgical scar that showed subtle changes on sequential sonograms. The imaging findings of this case were subtle but the mass that had been shrinking developed an angular margin in one region. These findings, along with the penetrating vascularity revealed on Doppler, prompted us to proceed to a biopsy of the lesion. It was of critical importance to compare the size and the shape of the lesion with previous ultrasounds in order to exclude malignancy in any iatrogenically altered lesion. Based on this case, we conclude that whenever a subtle change is detected, at a surgical site, a biopsy should be performed. Breast cancer developing from a surgical scar is rare; this type of malignancy has been reported in only 12 cases to date. Herein, we report on a 52-year-old female who developed infiltrating ductal carcinoma in a surgical scar following excision of a benign mass. Two years previously, the patient underwent surgery and radiotherapy for invasive ductal carcinoma of the contralateral breast. The initial appearance of the scar was similar to fat necrosis; it was observed to be progressively shrinking on follow-up sonography. On the two year follow-up ultrasound, the appearance changed, an angular margin and vascularity at the periphery of the scar were noted. A biopsy and subsequent excision of the scar were performed; the diagnosis of infiltrating ductal carcinoma of the scar was

    The scar is a major problem in the medical profession. Its timely treatment is very important for the better outcome of the scar treatment and for the improvement of the life quality of the patients. The aim of this study was retrospectively analyzed the epidemiological characteristics affecting the efficacy of the scar surgical treatment of the people in the western part of China. Total 414 scar cases were retrospectively analyzed to clarify the epidemiological characteristics and the factors affecting the scar surgical treatment efficacy. The factors included were sex, age, area distribution, treatment seasons, injury sites, injury causes, and the time from scarring to the surgical treatment. All scar cases were surgically treated with the repairing technology including skin graft, flap and soft tissue dilation. There were 206 males and 208 females with the average age 20.53±12.9 years (age range 1-68 years). The patient proportions in the age groups of 0-20, 21-40 and >40 years were 61.4% (254 cases), 29.2% (121 cases), and 9.4% (39 cases) respectively. The patient's attendance rate reached the highest during the summer and winter. Most patients were from the rural areas with an increasing tendency each year. The burn scars were the most abundant and the injury sites were mostly the head and face. Univariate analysis showed that the time from scarring to the surgical treatment and the injury sites were significantly influenced the scar surgical treatment efficacy. Logistic regression analysis demonstrated that the injured sites of the head and face significantly influenced the scar surgical treatment efficacy. With the development of economy in China, more scar patients especially younger and children visit doctors predominantely from the rural areas. Usually, they get their scars in the exposed area of their bodies (head and face) which seriously affect the patient's appearance and function. Factors influencing the scar surgical treatment efficacy has

    Objective: To assess the clinical presentation and management of patients with epilepsy presenting with periocular post burn scarring. Results: There were 18 (78.26%) female and 5(21.73%) male patients. The age range was from 18 to 45 years with a mean of 28 years. In 17 (73.91%) patients, lid contracture was released to cover their eyeballs. In 6 (26.08%) patients the eyeball was lost due to late presentation. Conclusion: There should be a high index of suspicion in facial burns for ophthalmic damage and early referral to an ophthalmologist should be made to prevent complications. Early release of contracture with application of full or partial thickness skin grafts is advisable. (author)

    Objective: To analyze MRI findings of cesarean scar pregnancy (CSP). Methods: The MR findings in 18 patients who were diagnosed as CSP by surgery from March 2010 to November 2011 were retrospectively analyzed, and comparison was made between the MRI findings and surgical results. Results: All Gestational sacs (18) were clearly detected by MRI. Among the 18 cases,gestational sac presented as cystic mass with smooth margin located within the scar of uterine wall at the lower anterior uterus in 16 cases. In 2 of the 16 cases, gestational sac was found within the myometrium, whereas in the remaining 14 cases, gestational sac was found partially within the myometrium with extension into the uterine cavity. The anterior wall of isthmus uteri became thinner. In the remaining 2 of the 18 cases, gestational sac presented as irregular, multilobolated mass, growing deep into the myometrium as well as into the uterine cavity. On T 2 WI, the mass showed heterogeneous signal intensity. A small amount of hemorrhage within the mass and uterine cavity could be seen on T 1 WI. An enhancing solid component with a heterogeneous mass could be seen. All gestational sacs in 18 cases were located at or adjacent to the previous cesarean scar. In the area of cesarean scar,the signal of the uterine wall was disconnected, with focal indentation or thinning and the previous cesarean scar exhibited hypointensity on both T 1 WI and T 2 WI. Conclusion: CSP has its unique findings on MRI, these specific features can provide useful information in the management of CSP. (authors)

    Scars after facial trauma or surgery can be a source of distress for patients, and facial plastic surgeons are frequently called upon to help manage them. Although no technique can remove a scar, numerous treatment modalities have been developed to improve facial scar appearance with varying levels of invasiveness. This article reviews techniques that camouflage scars without surgical intervention. Topical scar treatments, camouflage cosmetics, use of hairstyling and glasses, and facial prosthetics are discussed. In addition, professional counseling is provided on selection and application of topical cosmetics for use as part of an office practice. 2011 Elsevier Inc. All rights reserved.

    Abnormal (keloid and hypertrophic) scars are a significant affliction with no satisfactory single modality therapy to-date. Available options are often ineffective, painful, potentially hazardous, and require healthcare personnel involvement. Herein a self-administered microneedle device based on drug-free physical contact for inhibiting abnormal scars is reported. Its therapeutic activity through microneedle contact eliminates hazards associated with toxic anti-scarring drugs while self-treatment enables administration flexibility. The microneedle patch was fabricated with FDA-approved liquid crystalline polymer under good manufacturing practice. It was first tested to ascertain its ability to inhibit (keloid) fibroblast proliferation. Later the microneedle patch was examined on the rabbit ear hypertrophic scar model to explore its potential in inhibiting the generation of abnormal scars post-injury. Finally, the microneedle patch was applied to the caudal region of a hypertrophic scar located on a female patient's dorsum to verify clinical efficacy. On untreated control cultures, barely any non-viable fibroblasts could be seen. After 12-h treatment with the microneedle patch, the non-viable proportion increased to 83.8 ± 11.96%. In rabbit ear hypertrophic scar model, 100% of the control wounds without the presence of patches on rabbit ears generated regions of raised dermis originating from the wound site (3/3), whereas microneedle treatment prevented dermis tissue thickening in 83.33% of the wounds (15/18). In the clinical test, the microneedle patch was well tolerated by the patient. Compared to the untreated region, microneedle treatment decreased the number of infiltrated inflammatory cells, with less disrupted dermis tissue architecture and more flattened appearance. A self-administered, drug-free microneedle patch appears highly promising in reducing abnormal scarring as observed from in vitro, in vivo and clinical experiments. Larger cohort clinical

    Keloids and hypertrophic scars are prevalent and psychologically distressful dermatologic conditions. Various treatment modalities have been tried but without complete success by any one method. We evaluated the efficacy of a combination of intense pulsed light (IPL) device and intralesional corticosteroid injection for the treatment of keloids and hypertrophic scars with respect to the recovery of skin barrier function. Totally 52 Korean patients were treated by the combined treatment at 4-8-week intervals. Using digital photographs, changes in scar appearance were assessed with modified Vancouver Scar Scale (MVSS), physicians' global assessment (PGA) and patient's satisfaction score. In 12 patients, the stratum corneum (SC) barrier function was assessed by measuring transepidermal water loss (TEWL) and SC capacitance. Most scars demonstrated significant clinical improvement in MVSS, PGA and patient's satisfaction score after the combined therapy. A significant decrease of TEWL and elevation of SC capacitance were also documented after the treatment. The combination therapy (IPL + corticosteroid injection) not only improves the appearance of keloids and hypertrophic scars but also increases the recovery level of skin hydration status in terms of the skin barrier function.

    Hypertrophic scar pain, pruritus, and paresthesia symptoms are major and particular concerns for burn patients. However, because no effective and satisfactory methods exist for their alleviation, the clinical treatment for these symptoms is generally considered unsatisfactory. Therefore, their risk factors should be identified and prevented during management. We reviewed the medical records of 129 post-burn hypertrophy scar patients and divided them into two groups for each of three different symptoms based on the University of North Carolina "4P" Scar Scale: patients with scar pain requiring occasional or continuous pharmacological intervention (HSc pain, n=75) vs. patients without such scar pain (No HSc pain, n=54); patients with scar pruritus requiring occasional or continuous pharmacological intervention (HSc pruritus, n=63) vs. patients without such scar pruritus (No HSc pruritus, n=66); patients with scar paresthesia that influenced the patients' daily activities (HSc paresthesia, n=31) vs. patients without such scar paresthesia (No HSc paresthesia, n=98). Three multivariable logistic regression models were built, respectively, to identify the risk factors for hypertrophic burn scar pain, pruritus, and paresthesia development. Multivariable analysis showed that hypertrophic burn scar pain development requiring pharmacological intervention was associated with old age (odds ratio [OR]=1.046; 95% confidence interval [CI], 1.011-1.082, p=0.009), high body mass index(OR=1.242; 95%CI,1.068-1.445, p=0.005), 2-5-mm-thick post-burn hypertrophic scars (OR=3.997; 95%CI, 1.523-10.487; p=0.005), and 6-12-month post-burn hypertrophic scars (OR=4.686; 95%CI; 1.318-16.653; p=0.017). Hypertrophic burn scar pruritus development requiring pharmacological intervention was associated with smoking (OR=3.239; 95%CI, 1.380-7.603; p=0.007), having undergone surgical operation (OR=2.236; 95%CI, 1.001-4.998; p=0.049), and firm scars (OR=3.317; 95%CI, 1.237-8.894; p=0.017).

    Very few clinical trials have investigated the effect of topical acne treatment on scarring. Our objective was to evaluate the efficacy of adapalene 0.3%/benzoyl peroxide 2.5% gel (A0.3/BPO2.5) in atrophic acne scar formation in patients with acne. In this multicenter, randomized, investigator-blinded, vehicle-controlled study, subjects with moderate or severe facial acne (Investigator's Global Assessment [IGA] score 3 or 4; ≥ 25 inflammatory lesions; ten or more atrophic acne scars) applied A0.3/BPO2.5 or vehicle daily per half face for 24 weeks. Subjects with acne requiring systemic treatment were excluded. Assessments included investigator atrophic acne scar count, Scar Global Assessment (SGA), acne lesion count, IGA, skin roughness and skin texture, subject self-assessment of clinical acne-related scars and satisfaction questionnaire, tolerability, and safety. Included subjects (n = 67) had mainly moderate acne (92.5% IGA 3); mean scores at baseline were approximately 40 acne lesions and 12 scars per half face. By week 24, the change from baseline in total scar count was - 15.5% for A0.3/BPO2.5 versus  + 14.4% for vehicle (approximately 30% difference), with a mean of 9.5 scars versus 13.3 per half face, respectively (p vehicle (p vehicle (p vehicle side, most commonly skin irritation (14.9 vs. 6%, respectively). Topical A0.3/BPO2.5 prevented and reduced atrophic scar formation. Scar count increased with vehicle (+ 14.4%) but decreased with A0.3/BPO2.5 (- 15.5%) over 24 weeks.

    AIM To describe a series of patients with aberrant polypoid nodule scar developed after gastric endoscopic submucosal dissection (ESD), and to discuss its pathogenesis and clinical management. METHODS We reviewed retrospectively the endoscopic database of two academic institutions located in Brazil and Japan and searched for all patients that underwent ESD to manage gastric neoplasms from 2003 to 2015. The criteria for admission in the study were: (1) successful en bloc ESD procedure with R0 and curative resection confirmed histologically; (2) postoperative endoscopic examination with identification of a polypoid nodule scar (PNS) at ESD scar; (3) biopsies of the PNS with hyperplastic or regenerative tissue, reviewed by two independent experienced gastrointestinal pathologists, one from each Institution. Data were examined for patient demographics, Helicobacter pylori status, precise neoplastic lesion location in the stomach, tumor size, histopathological assessment of the ESD specimen, and postoperative information including medical management, endoscopic and histological findings, and clinical outcome. RESULTS A total of 14 patients (10 men/4 women) fulfilled the inclusion criteria and were enrolled in this study. One center contributed with 8 cases out of 60 patients (13.3%) from 2008 to 2015. The second center contributed with 6 cases (1.7%) out of 343 patients from 2003 to 2015. Postoperative endoscopic follow-up revealed similar findings in all patients: A protruded polypoid appearing nodule situated in the center of the ESD scar surrounded by convergence of folds. Biopsies samples were taken from PNS, and histological assessment revealed in all cases regenerative and hyperplastic tissue, without recurrent tumor or dysplasia. Primary neoplastic lesions were located in the antrum in 13 patients and in the angle in one patient. PNS did not develop in any patient after ESD undertaken for tumors located in the corpus, fundus or cardia. All patients have been

    To illustrate a laparoscopic technique for the resection of cesarean scar ectopic pregnancy, associated with isthmocele repair. Case report (Canadian Task Force classification III). A tertiary referral center in Strasbourg, France. Cesarean scar pregnancy is a rare form of ectopic pregnancy. The major risk of this type of pregnancy is the early uterine rupture with massive, sometimes life-threatening, bleeding. Thus, active management of these pregnancies starting immediately after diagnosis is crucial. Therapeutic options can be medical, surgical, or a combination. Numerous case reports or case series can be found in the literature, but there are few clinical studies, which are difficult to conduct because of case rarity and inconclusiveness. A 2016 meta-analysis that included 194 articles published between 1978 and 2014 (126 case reports, 45 cases series, and 23 clinical studies) concluded that hysteroscopy or laparoscopic hysterotomy seems to be the best first-line approach to treating cesarean scar ectopic pregnancy, with uterine artery embolization reserved for significant bleeding and/or a high suspicion index for arteriovenous malformation [1]. There is no consensus on the treatment of reference, however. The case involves a 38-year-old primiparous women who underwent a cesarean section delivery in 2010 and who was diagnosed by ultrasound scan at 7 weeks gestation with cesarean scar ectopic pregnancy, which was confirmed by pelvic magnetic resonance imaging. The patient initially received medical treatment with 2 intramuscular injections of methotrexate and one local intragestational injection of KCl. Her initial human chorionic gonadotropin (hCG) level was 82 000 IU/L. Rigorous weekly biological and ultrasound monitoring revealed an involution of the ectopic pregnancy associated with decreasing hCG. No bleeding or infectious complications occurred during this period. After 10 weeks of monitoring, her hCG had stabilized at 300 IU/L, and a residual image

    Patients with non-ischaemic cardiomyopathy (NICM) and ventricular tachycardia can be categorized as anteroseptal (AS) or inferolateral (IL) scar sub-types based on imaging and voltage mapping studies. The aim of this study was to correlate the baseline electrocardiogram (ECG) with endo-epicardial voltage maps created during ablation procedures and identify the ECG characteristics that may help to distinguish the scar as AS or IL. We assessed 108 baseline ECGs; 72 patients fulfilled criteria for dilated cardiomyopathy whereas 36 showed minimal structural abnormalities. Based on the unipolar low-voltage distribution, the scar pattern was classified as predominantly AS (n = 59) or IL (n = 49). Three ECG criteria (PR interval 230 ms or QRS > 170 ms or an r ≤ 0.3 mV in V3 having 92 and 81% of sensitivity and specificity, respectively, in predicting AS scar pattern. A significant negative correlation was found between the extension of the endocardial unipolar low voltage area and left ventricular EF (r s = -0.719, P < 0.001). The extent of endocardial AS unipolar low voltage was correlated with PR interval and QRS duration (r s = 0.583 and r s = 0.680, P < 0.001, respectively) and the IL epicardial unipolar low voltage with the mean voltage of the limb leads (r s = -0.639, P < 0.001). Baseline ECG features are well correlated with the distribution of unipolar voltage abnormalities in NICM and may help to predict the location of scar in this population.

    Lee, Y; Kumar, P; Mitchell, M [University of Kansas Medical Center, Kansas City, KS (United States)

    2015-06-15

    Purpose: Breast cancer patients who undergo a mastectomy often require post-mastectomy radiation therapy (PMRT) due to high risk disease characteristics. PMRT usually accompanies scar boost irradiation (10–16Gy in 5–8 fractions) using en face electrons, which often results in increased dose to the underlying lungs, thereby potentially increasing the risk of radiation pneumonitis. Hence, this study evaluated water-equivalent phantoms as energy degraders and as an alternative to a bolus to reduce radiation dose to the underlying lungs for electron scar boost irradiation. Methods: Percent depth dose (PDD) profiles of 6 MeV (the lowest electron energy available in most clinics) were obtained without and with commercial solid water phantoms (1 to 5mm by 1mm increments) placed on top of electron cones. Phantom attenuation was measured by taking a ratio of outputs with to without the phantoms in 10×10cm2 cone size for monitor unit (MU) calculation. In addition, scatter dose to contralateral breast was measured on a human-like phantom using two selected scar (short and long) boost patient setups. Results: The PDD plots showed that the solid water phantoms and the bolus had similar dosimetric effects for the same thickness. Lower skin dose (up to 3%) to ipsilateral breast was observed with a 5mm phantom compared with a 5mm bolus (up to 10%) for all electron cones. Phantom attenuation was increased by 50% with about a 4.5mm phantom. Also, the energy degraders caused scatter dose to contralateral breast by a factor of 3 with a 5mm phantom. Conclusion: Our results demonstrate the feasibility of using water-equivalent phantoms to reduce lung dose using en face electrons in patients with a thin chest wall undergoing PMRT. The disadvantages of this treatment approach (i.e., the increase in MUs and treatment time, and clinically insignificant scatter dose to the contralateral breast given usually 10Gy) are outweighed by its above clinical benefits.

    Full Text Available Background and Design: Postoperative scar development is an important problem for patients treated in plastic surgery clinics. Most patients think that continuous intradermal suturing is superior to interrupted suturing because they assume that it creates less scarring. We evaluated scars that form following intradermal and interrupted suturing. This article presents our controlled study that objectively compared the scars on patients' faces using a wound evaluation scale. Materials and Methods: Thirty-five patients, who had undergone operations on the bilateral cheeks, were included in this study. Thirty patients were female; five patients were male. Their mean age was 40.05 years. The average scar evaluation time after surgery was 9.05 months. Elliptical excisions were made on the lesions under local anesthesia. The incisions on the right cheeks were sutured with 6/0 monofilament nonabsorbable sutures using the continuous intradermal suturing technique. The left cheek incisions were sutured with same sutures using the interrupted suturing method. Results: The patients were evaluated 7–11 months after operation (mean: 9.05 months using the Stony Brook Scar Evaluation Scale. A Related Samples T-test was used for statistical evaluation of the differences between the suturing techniques. No significant differences were noted in scar formation between the two suturing methods (p>0.05. Conclusion: We found no differences in scar formation between the two frequently used suturing techniques studied here. We believe that the suturing technique is a less important determinant of scar formation than are other factors.

    Integra artificial skin is a porous matrix used as a permanent dermal replacement. Developed in the 1970's, it has been used successfully in the treatment of acute bums requiring full or deep partial thickness skin replacement. Three patients with burn scars received Integra Artificial Skin to resurface various areas of burn scars and also contractures. The first was a 24-year-old woman who had two pieces of Integra to resurface a forearm/elbow/wrist defect. The second was a 28-year-old woman who had two pieces of Integra to resurface a neck contracture. The third was a 44 year-old woman who had two pieces to correct severe burn contractures/ scars of her hands. The results of these three patients, probably the first time Integra was used for bum scar and contracture revision, indicate that there is a place for Integra in Burn Scar surgery. However, the basic principle of its application must be adhered to. These include excision to remove the complete scar, recreation of original size of skin defect and meticulous application of the Artificial Skin and its care post-operatively. Details of its application will be highlighted

    The Er:YAG laser, considered to be less effective than CO 2 laser in its traditional form, in its new modulated version has variable pulse technology that is claimed to be superior to the earlier versions of the laser. The aim of the study was to check efficacy and safety of the new variable square pulse (VSP) Er:YAG laser in the management of acne scar in patients with Fitzpatrick skin types IV and V. This retrospective study consisted of 80 patients (Fitzpatrick skin types IV and V) with atrophic and hypertrophic facial acne scars. Records of the patients who had undergone four treatment sessions with VSP technology equipped with Er:YAG laser were extracted. Each patient had undergone a minimum of four sessions. Fractional mode at medium laser pulse (SP) and long pulse (LP) was employed for the depressed center of the scars to stimulate neocollagenogenesis. Short laser pulse (MSP) in nonfractionated mode was used for ablating the raised scar border and hypertrophic scars. Goodman and Baron global scarring grading system was used for qualitative and quantitative assessments. Patient's satisfaction to the treatment and observer's assessment of improvement (based on photographs) was graded as poor (75% improvement). At the end of the four sessions, the number of patients in grade IV postacne scarring reduced from 16 to 2 and that in grade III from 47 to 29. The mean score significantly dropped from 36.94 to 27.5. Subjective assessment revealed that 78 of 80 patients had noticed more than 25% improvement, with 50 of them showing more than 50% improvement at the end of four sessions. Eight patients perceived an excellent response and 42 reported a good response. This is notably higher than the observer's grading, which showed an excellent response in only 2 patients and a good response in 35. Adverse effects were limited to prolonged erythema (two patients), prolonged crusting (one patient), and postinflammatory hyperpigmentation (one patient). Ninety-seven percent of

    Conclusion:. Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography may be advocated in patients with abdominal scars.

    Chemical peeling with both alpha and beta hydroxy acids has been used to improve acne scarring with pigmentation. Lactic acid, a mild alpha hydroxy acid, has been used in the treatment of various dermatological indications but no study is reported in acne scarring with pigmentation. To evaluate the efficacy and safety of full strength pure lactic acid 92% (pH 2.0) chemical peel in superficial acne scarring in Indian skin. Seven patients, Fitzpatrick skin type IV-V, in age group 20-30 years with superficial acne scarring were enrolled in the study. Chemical peeling was done with lactic acid at an interval of 2 weeks to a maximum of four peels. Pre- and post-peel clinical photographs were taken at every session. Patients were followed every month for 3 months after the last peel to evaluate the effects. At the end of 3 months, there was definite improvement in the texture, pigmentation, and appearance of the treated skin, with lightening of scars. Significant improvement (greater than 75% clearance of lesions) occurred in one patient (14.28%), good improvement (51-75% clearance) in three patients (42.84%), moderate improvement (26-50% clearance) in two patients (28.57%), and mild improvement (1-25% clearance) in one patient (14.28%). © 2010 Wiley Periodicals, Inc.

    Research into the pathophysiology and treatment of hypertrophic scar (HSc) remains limited by the heterogeneity of scar and the imprecision with which its severity is measured. The objective of this study was to test the interrater reliability and concurrent validity of the Cutometer measurement of elasticity, the Mexameter measurement of erythema and pigmentation, and total thickness measure of the DermaScan C relative to the modified Vancouver Scar Scale (mVSS) in patient-matched normal skin, normal scar, and HSc. Three independent investigators evaluated 128 sites (severe HSc, moderate or mild HSc, donor site, and normal skin) on 32 burn survivors using all of the above measurement tools. The intraclass correlation coefficient, which was used to measure interrater reliability, reflects the inherent amount of error in the measure and is considered acceptable when it is >0.75. Interrater reliability of the totals of the height, pliability, and vascularity subscales of the mVSS fell below the acceptable limit ( congruent with0.50). The individual subscales of the mVSS fell well below the acceptable level (0.89) for each study site with the exception of severe scar. Mexameter and DermaScan C reliability measurements were acceptable for all sites (>0.82). Concurrent validity correlations with the mVSS were significant except for the comparison of the mVSS pliability subscale and the Cutometer maximum deformation measure comparison in severe scar. In conclusion, the Mexameter and DermaScan C measurements of scar color and thickness of all sites, as well as the Cutometer measurement of elasticity in all but the most severe scars shows high interrater reliability. Their significant concurrent validity with the mVSS confirms that these tools are measuring the same traits as the mVSS, and in a more objective way.

    2015-01-01

    Full Text Available Introduction: Acne scars are the result of inflammation within the dermis brought on by acne. The scar is created by the wound trying to heal itself resulting in too much collagen in one spot. Current treatment available are not much satisfactory. Microneedling injure the dermis, thereby stimulating collagen formation. Glycolic acid acts as vehicle for delivery of drugs to dermis: in addition to that, it also has a role in collagen induction. Tretinoin helps in collagen formation. Salicylic acid remodel the superficial skin after the treatment. Material and Methods: A total of 4 patients in which 3 out of 4 patient, grade 3 acne scars and 1 out of 4 had grade 2 scar were treated with the regime. After taking consent 35% Glycolic acid peeling was done followed by microneedling. From the next day 12% Glycolic acid plus 0.05% Tretinoin is applied once a day for 2 months. After 2 months 30% Salicylic acid peeling is done. Photographs were taken before treatment, after 1 month and after 2 months of completion of the therapy and compared. Objective assessment was done according to Global Acne Scarring Classification. Result: subjectively 2 patients reported excellent response and 2 patients reported good response. Objectively, all patients showed good to excellent response. Conclusion: Zonun’s regime may be effective for treatment of acne scars.

    Cesarean scar pregnancy (CSP) and cesarean scar dehiscence (CSD) are the most dreaded complications of cesarean scar (CS). As the incidence of CS is increasing worldwide, so is the incidence of CSP, especially in cases with assisted reproduction techniques. It is of utmost importance to diagnose CSP in the early first trimester, as it can lead to myometrial rupture with fatal outcome. On the other hand, CSD may be encountered during pregnancy or in the postpartum period. CSD in the postpartum period is very rare and can cause secondary postpartum hemorrhage (PPH) leading to increased maternal morbidity or even death if not diagnosed and managed promptly. Both complications can be diagnosed on ultrasonography (USG) and confirmed on magnetic resonance imaging (MRI). These two conditions carry high morbidity and mortality. In this article, we highlight the role of imaging in the early diagnosis and management of these conditions

    Background: Fractional photothermolysis is one of the most effective treatment options used to resurface scars of different aetiologies. Aim: To assess the efficacy and safety of fractional CO2 laser resurfacing treatment in the management of non-hypertrophic traumatic and burn scars. Materials and Methods: Twenty-five patients affected by non-hypertrophic traumatic and burn scars were treated with four sessions of fractional CO2 laser resurfacing treatment at 6-weekly intervals. Patients were photographed at each visit and finally, 3 months after the end of treatment schedule. Response to treatment was assessed clinically as well as by comparing the initial photograph of the patient with the one taken at the last follow-up visit 3-months after the final treatment session. Changes in skin texture, surface irregularity and pigmentation were assessed on a quartile grading scale and scored individually from 0 to 4. A mean of the three individual scores was calculated and the response was labelled as ‘excellent’ if the mean score achieved was >2. A score of 1-2 was labeled as good response while a score below 1 was labeled as ‘poor’ response. The subjective satisfaction of each patient with the treatment offered was also assessed at the last follow-up visit. Results: The commonest site of scarring treated was the face followed by hands. Response to treatment was rated as excellent in 60% (15/25) patients while 24% (6/25) and 16% (4/25) patients were labeled as good and poor responders, respectively. Skin texture showed better response than other variables with average score of 2.44. Linear post-traumatic scars were seen to respond less than other morphological types. Majority of the patients (19 out of 25) were highly satisfied with the treatment offered. No long-term adverse effects were noted in any patient. Conclusions: Fractional photothermolysis with a fractional CO2 laser gives excellent results in patients with post-burn scars with minimal adverse

The subjective satisfaction of each patient with the treatment offered was also assessed at the last follow-up visit. Results: The commonest site of scarring treated was the face followed by hands. Response to treatment was rated as excellent in 60% (15/25 patients while 24% (6/25 and 16% (4/25 patients were labeled as good and poor responders, respectively. Skin texture showed better response than other variables with average score of 2.44. Linear post-traumatic scars were seen to respond less than other morphological types. Majority of the patients (19 out of 25 were highly satisfied with the treatment offered. No long-term adverse effects were noted in any patient. Conclusions: Fractional photothermolysis with a fractional CO 2 laser gives excellent results in patients with post-burn scars with

    We describe the MR appearance of fibrous scars in the infrapatellar fat pad after arthroscopy. The subjects were 96 patients who underwent arthroscope-assisted anterior cruciate ligament (ACL) reconstruction and were examined by oblique sagittal MR imaging at different follow-up intervals. Two observers evaluated the characteristics of the fibrous scars in the infrapatellar fat pad. All fibrous scars with low signal intensity were accentuated at the portal and coursed horizontally through the infrapatellar fat pad. The fibrous scar within the fat pad occurred and peaked within 6 months after arthroscopy. It then subsided gradually and had disappeared by one year later in nearly half of the patients. Identifying MR imaging characteristics of fibrous scars in the fat pad after arthroscopy may be clinically helpful to differentiate these scars from other abnormalities that involve the infrapatellar fat pad.

  12. Scars of the Wigner Function.

    2001-01-01

    We propose a picture of Wigner function scars as a sequence of concentric rings along a two-dimensional surface inside a periodic orbit. This is verified for a two-dimensional plane that contains a classical hyperbolic orbit of a Hamiltonian system with 2 degrees of freedom. The stationary wave functions are the familiar mixture of scarred and random waves, but the spectral average of the Wigner functions in part of the plane is nearly that of a harmonic oscillator and individual states are also remarkably regular. These results are interpreted in terms of the semiclassical picture of chords and centers.

    We study the correspondence between phase-space localization of quantum (quasi-)energy eigenstates and classical correlation decay, given by Ruelle-Pollicott resonances of the Frobenius-Perron operator. It will be shown that scarred (quasi-)energy eigenstates are correlated: pairs of eigenstates strongly overlap in phase space (scar in same phase-space regions) if the difference of their eigenenergies is close to the phase of a leading classical resonance. Phase-space localization of quantum states will be measured by L 2 norms of their Husimi functions

    Twenty-nine kidneys of seventeen patients (nine boys and eight girls) with vesicoureteral reflux and repeated urinary tract infection were studied by magnetic resonance imaging for diagnosis of renal scarring and correlation between clinical data and the degree renal scarring. Renal scarring is classified into three types according to findings in magnetic resonance imaging. The degree of renal scarring are classified into five grades according to traditional grading of intravenous pyelogram. If a fine deformity of calyx is shown on intravenous pyelogram, magnetic resonance imaging demonstrates renal scarring. Magnetic resonance imaging without irradiation is exceedingly valuable for the diagnosis of renal scarring. The appearances of magnetic resonance imaging were supported by X-ray computed tomography. There is a substantial correlation between serum creatinine and the grades of renal scarring by magnetic resonance imaging. There is a substantial correlation between fever attacks and the grade of renal scarring, and there is a significant reverse correlation between the age of the onset of upper urinary tract infection and the grade of renal scarring. It is suggested that upper urinary tract infection is the most significant factor in scar formation. (author)

    Purpose: Evaluation of the results of perioperative interstitial brachytherapy with low dose-rate (L.D.R.) Ir-192 in the treatment of keloid scars. Patients and methods: We performed a retrospective analysis of 73 histologically confirmed keloids (from 58 patients) resistant to medico surgical treated by surgical excision plus early perioperative brachytherapy. All lesions were initially symptomatic. Local control was evaluated by clinical evaluation. Functional and cosmetic results were assessed in terms of patient responses to a self-administered questionnaire. Results: Median age was 28 years (range 13-71 years). Scars were located as follows: 37% on the face, 32% on the trunk or abdomen, 16% on the neck, and 15% on the arms or legs. The mean delay before loading was four hours (range, 1-6 h). The median dose was 20 Gy (range, 15-40 Gy). Sixty-four scars (from 53 patients) were evaluated. Local control was 86% (follow-up, 44.5 months; range, 14-150 months). All relapses occurred early within 2 years posttreatment. At 20 months, survival without recurrence was significantly lower when treated lengths were more than 6 cm long. The rate was 100% for treated scars below 4.5 cm in length, 95% (95% CI: 55-96) for those 4.5-6 cm long, and 75% (95% CI: 56-88) beyond 6 cm (p = 0.038). Of the 35 scars (28 patients) whose results were reassessed, six remained symptomatic and the esthetic results were considered to be good in 51% (18/35) and average in 37% (13/35) (median follow-up, 70 months; range, 16-181 months). Conclusion: Early perioperative L.D.R. brachytherapy delivering 20 Gy at 5 mm reduced the rate of recurrent keloids resistant to other treatments and gave good functional results. (authors)

    A suture line placed with the same direction as the relaxed skin tension line leads to good healing, but a suture line with over 30 degrees of angle from the relaxed skin tension line leads to longer healing time and more prominent scarring. W-plasty is widely used to change the direction of the scar or to divide it into several split scars. In this study, we applied W-plasty to patients with facial lacerations in the emergency department. From June 2012 to December 2014, 35 patients underwent simple repair or W-plasty for facial lacerations. Patients in the simple repair group underwent resection following a thermal margin, and the W-plasty group was resected within a pre-designed margin of W-shaped laceration. We assessed prognosis using the Stony Brook Scar Evaluation Scale (SBSES) after 10 days (short-term) and six months (long-term), respectively, following suture removal. Among 35 patients, 15 (42.9%) underwent simple debridement and 20 (57.1%) underwent W-plasty. In the W-plasty group, there was no difference between short-term and long-term follow-up showing high SBSES, but in the simple debridement group, long-term follow-up SBSES significantly decreased. W-plasty SBSES was higher than simple debridement at short-term as well as long-term follow-up. We experienced good results of direct W-plasty application at six-month long-term follow-up. Therefore, W-plasty application is more effective in reducing scar appearance than a simple debridement method for facial laceration patients with an angle of 30 degrees or more to the relaxed skin tension line.

    Full Text Available Among wound-healing modalities, platelet-rich plasma (PRP has been used for wound healing, through the release of multiple growth factors. The platelets mediate wound healing by initiating the clotting pathway and the subsequent matrix remodelisation. The aim of the work was to study the role of injection of platelet-rich plasma in the treatment of scars. This study was conducted on thirty patients who were divided into two groups (A and B. Each group included fifteen patients. The two groups were randomly distributed by using individual sealed envelopes. Group A was subjected to subcision of their acne scars using Nokor needle, followed by suction. Group B patients were subjected to the same treatment but followed by an injection of platelet-rich plasma once per month over three months. In Group A, 6 patients (40% showed moderate improvement, 5 patients (33.3% showed slight improvement and 4 patients (26.7% showed significant improvement. In Group B, 7 patients (46.7% showed moderate improvement, 5 patients (33.3% showed marked improvement and 3 patients (20% showed significant improvement. There was a statistically significant difference on the independent observer’s after-treatment assessment between the groups (P=0.014. In conclusion, subcision suction leads to a persistent improvement of acne scars in a short time, and the coupling with injection of PRP is the most effective in the treatment of depressed facial scars.

    In eight beagles following laminectomies, dynamic contrast enhancement of posterior epidural scar was assessed sequentially over 4 months by means of FLASH sequence (20/10/50) following Gd-DTPA. A consistent pattern of enhancement was apparent in all dogs. Maximum enhancement occurred after 1 month (80%-130%), with peak enhancement at 7-10 minutes. There was decreased enhancement each succeeding month with a similar time to peak. Time curves were obtained for blood, muscle, and scar following injection of 40 μCi Gd-153 DTPA and correlated well with in vivo MR image intensities. Histology showed granulation tissue early following surgery, which matured to scar by 4 months. These findings are in contrast to reports of enhancement of anterior scar in humans irrespective of age. The difference may be secondary to location in that posterior scar does not receive the trauma and stress acting on anterior scar associated with a degenerative disk

    The comparison of scar evaluation over time requires measurement tools with acceptable intrarater reliability and the ability to discriminate skin characteristics of interest. The objective of this study was to evaluate the intrarater reliability and sensitivity and specificity of the Cutometer, the Mexameter, and the DermaScan C relative to the modified Vancouver Scar Scale (mVSS) in patient-matched normal skin, normal scar (donor sites), and hypertrophic scar (HSc). A single investigator evaluated four tissue types (severe HSc, less severe HSc, donor site, and normal skin) in 30 burn survivors with all four measurement tools. The intraclass correlation coefficient (ICC) for the Cutometer was acceptable (> or =0.75) for the maximum deformation measure for the donor site and normal skin (>0.78) but was below the acceptable range for the HSc sites and all other parameters. The ICC for the Mexameter erythema (>0.75) and melanin index (>0.89) and the DermaScan C total thickness measurement (>0.82) were acceptable for all sites. The ICC for the total of the height, pliability, and vascularity subscales of the mVSS was acceptable (0.81) for normal scar but below the acceptable range for the scar sites. The DermaScan C was clearly able to discriminate HSc from normal scar and normal skin based on the total thickness measure. The Cutometer was less discriminating but was still able to discriminate HSc from normal scar and normal skin. The Mexameter erythema index was not a good discriminator of HSc and normal scar. Receiver operating characteristic curves were generated to establish the best cutoff point for the DermaScan C total thickness and the Cutometer maximum deformation, which were 2.034 and 0.387 mm, respectively. This study showed that although the Cutometer, the DermaScan C, and the Mexameter have measurement properties that make them attractive substitutes for the mVSS, caution must be used when interpreting results since the Cutometer has a ceiling effect when

    Mesotherapy is a popular procedure that poses risks that include scarring, contour changes and bacterial infections. The benefits of the procedure remain to be objectively delineated in a placebo-controlled, blinded study. Despite the lack of evidence to support its use, it is marketed as a "nonsurgical and safe" way to remove fat. The authors report a case of mycobacterial infection resulting from mesotherapy. This infection should be considered when a patient presents with a mesotherapy complication and should be discussed with the patient prior to the procedure. Options for treatment of the scarring are considered.

    Deep dermal burns require tangential excision of non-viable tissue and skin grafting to improve wound healing and burn-scar quality. Tangential excision is conventionally performed with a knife, but during the last decade hydrosurgery has become popular as a new tool for tangential excision. Hydrosurgery is generally thought to be a more precise and controlled manner of burn debridement leading to preservation of viable tissue and, therefore, better scar quality. Although scar quality is considered to be one of the most important outcomes in burn surgery today, no randomized controlled study has compared the effect of these two common treatment modalities with scar quality as a primary outcome. The aim of this study is, therefore, to compare long-term scar quality after hydrosurgical versus conventional tangential excision in deep dermal burns. A multicenter, randomized, intra-patient, controlled trial will be conducted in the Dutch burn centers of Rotterdam, Beverwijk, and Groningen. All patients with deep dermal burns that require excision and grafting are eligible. Exclusion criteria are: a burn wound burned > 30%, full-thickness burns, chemical or electrical burns, infected wounds (clinical symptoms in combination with positive wound swabs), insufficient knowledge of the Dutch or English language, patients that are unlikely to comply with requirements of the study protocol and follow-up, and patients who are (temporarily) incompetent because of sedation and/or intubation. A total of 137 patients will be included. Comparable wound areas A and B will be appointed, randomized and either excised conventionally with a knife or with the hydrosurgery system. The primary outcome is scar quality measured by the observer score of the Patient and Observer Scar Assessment Scale (POSAS); a subjective scar-assessment instrument, consisting of two separate six-item scales (observer and patient) that are both scored on a 10-point rating scale. This study will contribute to

    Background: A number of treatments for reducing the appearance of acne scars are available, but general guidelines for optimizing acne scar treatment do not exist. The aim of this study was to compare the clinical effectiveness and side effects of fractional carbon dioxide (CO2) laser resurfacing combined with punch elevation with fractional CO2 laser resurfacing alone in the treatment of atrophic acne scars. Materials and Methods: Forty-two Iranian subjects (age range 18–55) with Fitzpatrick skin types III to IV and moderate to severe atrophic acne scars on both cheeks received randomized split-face treatments: One side received fractional CO2 laser treatment and the other received one session of punch elevation combined with two sessions of laser fractional CO2 laser treatment, separated by an interval of 1 month. Two dermatologists independently evaluated improvement in acne scars 4 and 16 weeks after the last treatment. Side effects were also recorded after each treatment. Results: The mean ± SD age of patients was 23.4 ± 2.6 years. Clinical improvement of facial acne scarring was assessed by two dermatologists blinded to treatment conditions. No significant difference in evaluation was observed 1 month after treatment (P = 0.56). Their evaluation found that fractional CO2 laser treatment combined with punch elevation had greater efficacy than that with fractional CO2 laser treatment alone, assessed 4 months after treatment (P = 0.02). Among all side effects, coagulated crust formation and pruritus at day 3 after fractional CO2 laser treatment was significant on both treatment sides (P < 0.05). Conclusion: Concurrent use of fractional laser skin resurfacing with punch elevation offers a safe and effective approach for the treatment of acne scarring. PMID:26538695

    2014-06-01

    There is not much level 1 evidence based literature to guide management of hypertrophic scars and keloids despite an array of therapeutic modalities at disposal. Intralesional (i/l) triamcinolone injections have remained a gold standard in non surgical management. Sporadic reports on use of i/l verapamil suggest its efficacy. Since verapamil has not found sufficient mention as an effective alternative modality, it was decided to undertake a randomized study which could also address some additional clinical parameters. A randomized, parallel group and observer blinded comparison with 40 patients (48 scars) was carried out to compare the effects of i/l triamcinolone (T) (22 scars) and verapamil injections (V) (26 scars). 1.5 ml was the maximum indicative volume decided in the study protocol for both the drugs (triamcinolone @40 mg/ml and verapamil @ 2.5 mg/ml). Patients included were aged between 15-60 years with scars ranging between 0.5-5 cm (but total area roughly scars under 2 years duration. Patients with keloidal diathesis were excluded. Injections were scheduled every three weeks until complete flattening of the scar or eight sessions, which ever came earlier. No concomitant therapies like massage, silicone gel or pressure garments were used. Scar evaluation at each stage was done by serial photographic records as well as by Vancouver Scar Scale (VSS). Comparative survival analysis between the two drugs was done using Kaplan Meier curves, and VSS scores were analyzed using Wilcoxon test and log rank test. Mean zero VSS scores were achieved with treatments in respect of scar height (T-12 weeks, V-21 weeks), vascularity (T-15 weeks, V-18 weeks) and pliability (T-15 weeks, V-21 weeks). The improvement in scar vascularity and pliability kept pace with decrease in scar height, in both the groups. There was not much difference in the rate of change of scar pigmentation with either drug but almost 60% patients in both the groups regained normal pigmentation. Our

    As a result of the current exponentially growing refugee population from the Middle-East and East Africa (Sudan, Darfur, Eritrea), clinicians (including forensic pathologists) are seeing atypical skin lesions, mainly of a traumatic nature, but in some cases associated with long-standing lesions related to ethnic practices. A case of torture sequelae is presented herein in a patient originally from Darfur (Sudan): cutaneous incisions were made on old scars several times using a knife. The clinical presentation of scarification lesions and that of atypically healed wounds (presumably an effect of inflammation induced by the introduction of irritating foreign bodies such as sand, salt, etc.) are completely different: in all cases they indicate a relative timeframe of the facts, which the clinician should not overlook in reconstructing the patient's course and the injuries to which he has been subjected (hence the proposed designation of "palimpsest scar", in the sense that a palimpsest is a manuscript on a parchment that previously contained writing but has been scratched clean to be overwritten). Thus, a "palimpsest scar" constitutes a fresh scar on top of and hiding another (ritual) scar in a context of ethnic cleansing. The diagnostic and clinical significance comes from the importance of differentiating between ethnic-type lesions and those induced by physical violence and abuse in a context of war.

    To estimate the incidence of scar endometriosis after different surgical procedures. A retrospective study of 72 patients diagnosed with scar endometriosis between 1978 and 2003 was performed. Patient age, site of endometriosis, previous operations, time-gap between last surgery and onset of symptoms, nodule characteristics, and recurrence were evaluated. Age ranged from 16 to 48 years. Location varied according to the previous surgery: 46 caesarean section, one hysterectomy, one in abdominal surgery, 19 episiotomy, one was a relapse and two pelvic floor procedures, two women with no previous surgery. The incidence of scar endometriosis after caesarean section was significantly higher than after episiotomy (0.2 and 0.06%, respectively: p<0.00001) with a relative risk of 3.3. Pain was the most frequent symptom. The mean time between surgery and onset of symptoms was 3.7 years. Our findings confirm that scar endometriosis is a rare condition and indicate, probably for the first time, that caesarean section greatly increases the risk of developing scar endometriosis.

    This report examines the localization of time harmonic high frequency modal fields in two dimensional cavities along periodic paths between opposing sides of the cavity. The cases where these orbits lead to unstable localized modes are known as scars. This paper examines the enhancements for these unstable orbits when the opposing mirrors are both convex and concave. In the latter case the construction includes the treatment of interior foci.

  10. Relationship Between Scarring and Dog Aggression in Pit Bull-Type Dogs Involved in Organized Dogfighting

    Full Text Available When pit bull-type dogs are seized in an investigation of organized dogfighting, heavily scarred dogs are often assumed to be highly dog aggressive due to a history of fighting. These dogs may be deemed dangerous and euthanized based on scarring alone. We analyzed our existing data on dogs seized from four dogfighting investigations, examining the relationship between the dogs’ scars with aggression towards other dogs. Scar and wound data were tallied in three body zones where dogfighting injuries tend to be concentrated. Dog aggression was assessed using a model dog and a friendly stimulus dog in a standardized behavior evaluation. Scarring and dog aggression were significantly related, more strongly among male (Fisher’s Exact p < 0.001 than female dogs (Fisher’s Exact p = 0.05. Ten or more scars in the three body zones was a reasonable threshold with which to classify a dog as high risk for dog aggression: 82% of males and 60% of females with such scarring displayed dog aggression. However, because many unscarred dogs were dog aggressive while some highly scarred dogs were not, we recommend collecting behavioral information to supplement scar counts when making disposition decisions about dogs seized in dogfighting investigations.

    Fractional microneedling radiofrequency (FMR) is one of the promising methods in acne treatment. Moreover, bipolar radiofrequency (BR) generates heat thereby which induces neocollagenosis. FMR may have the potential to be a safe and effective treatment for the patients both with acne and acne scar. This study was performed to compare the efficacy and safety of FMR and BR in acne and acne scar treatment. Furthermore, mechanism of the FMR treatment was investigated through skin tissues obtained from subjects. Twenty subjects with mild-to-moderate acne and acne scars were treated in a split-face manner with FMR and BR. Two sessions of treatment was done 4 weeks apart in a total 12-week prospective single-blind, randomized clinical trial. Clinical assessment and sebum measurement were carried out for the evaluation of efficacy and safety. Skin tissues were acquired for investigation of molecular changes. FMR was more effective for acne scar especially in icepick and boxcar scar compared to BR. Both inflammatory and non-inflammatory acne lesions decreased by 80 and 65 % in the FMR-treated side at the final visit of 12 weeks, respectively. FMR treatment resulted in significant reduction of sebum excretion. Both treatments showed no severe adverse effects other than erythema. The FMR showed superior efficacy in acne and acne scar compared with BR. Increased expression of TGFβ and collagen I and decreased expression of NF-κB, IL-8 are suggested to involve in the improvement of acne scar and acne lesion by FMR.

    Full Text Available Introduction: A periapical scar represents a clinically asymptomatic, non-progressive, small, periapical radiolucency in patients with a previously well-performed root canal treatment.The hypothesis: We introduce a hypothesis that periapical scar formation is caused by osseoinhibitory molecular signaling from the epithelial cell rests of Malassez.Evaluation of the hypothesis: When epithelial cell rests of Malassez are present in teeth with an infected root canal system, a periapical cyst develops, whereas in the case of a treated root canal system infection, periapical inflammation is diminished and the periapical leasion heals until the regeneration process reaches the apical part of the tooth where epithelial cell rests of Malassez are present. Cytokines cause rapidly progressive defensive fibroproduction and scar formation, in which osteoblasts cannot differentiate into

    There is no gold standard treatment for facial acne scars, and overall, little literature exists about the combination therapy for treatment of acne scar. The aim of this study was to evaluate the efficacy of fractionated microneedle radiofrequency (FMR) vs FMR combined with subcision for the treatment of atrophic acne scars. This was a randomized, split-face clinical study of 25 patients with II-IV Fitzpatrick skin types with moderate to severe facial atrophic acne scars. Initially, standard subcision by Nokor needle was performed on one side. Two weeks after subcision, FMR treatment was performed on both cheeks of each participant. Second and third FMR treatment sessions were performed within 4-week intervals. Two-blinded dermatologists performed clinical assessments using a quartile grading scale, and patients were also asked to judge their satisfaction using a visual analog scale (VAS) scoring system. The age of the patients varied from 24 to 40 years (mean: 30.08±4.94 years). Only nine patients (36%) were males. Clinical assessment by two-blinded dermatologists showed statistically significant improvement in the combination (FMR+subcision) group (P=.009). Patient satisfaction was statistically significantly better in the combination group (P=.001). A darkening of skin phototype was associated with a decrease in patient's satisfaction VAS score (P=.07). The combination of subcision and FMR is a safe and effective modality for mixed type acne scars. Additional randomized clinical study with long-term follow-up is necessary for further evaluation of FMR in combination with other procedures.

    Full Text Available BACKGROUND: In urban Guinea-Bissau, adults with a vaccinia scar had better survival but also a higher prevalence of HIV-2 infection. We therefore investigated the association between vaccinia scar and survival and HIV infection in a rural area of Guinea-Bissau. METHODOLOGY/PRINCIPAL FINDINGS: In connection with a study of HIV in rural Guinea-Bissau, we assessed vaccinia and BCG scars in 193 HIV-1 or HIV-2 infected and 174 uninfected participants. Mortality was assessed after 2(1/2-3 years of follow-up. The analyses were adjusted for age, sex, village, and HIV status. The prevalence of vaccinia scar was associated with age, village, and HIV-2 status but not with sex and schooling. Compared with individuals without any scar, individuals with a vaccinia scar had better survival (mortality rate ratio (MR = 0.22 (95% CI 0.08-0.61, the MR being 0.19 (95% CI 0.06-0.57 for women and 0.40 (95% CI 0.04-3.74 for men. Estimates were similar for HIV-2 infected and HIV-1 and HIV-2 uninfected individuals. The HIV-2 prevalence was higher among individuals with a vaccinia scar compared to individuals without a vaccinia scar (RR = 1.57 (95% CI 1.02-2.36. CONCLUSION: The present study supports the hypothesis that vaccinia vaccination may have a non-specific beneficial effect on adult survival.

    The phenotype and function of immune cells infiltrating the conjunctiva in scarring trachoma have yet to be fully characterized. We assessed tissue morphology and immunophenotype of cellular infiltrates found in trachomatous scarring compared to control participants. Clinical assessments and conjunctival biopsy samples were obtained from 34 individuals with trachomatous scarring undergoing trichiasis surgery and 33 control subjects undergoing cataract or retinal detachment surgery. Biopsy samples were fixed in buffered formalin and embedded in paraffin wax. Hematoxylin and eosin (H&E) staining was performed for assessment of the inflammatory cell infiltrate. Immunohistochemical staining of single markers on individual sections was performed to identify cells expressing CD3 (T-cells), CD4 (helper T-cells), CD8 (suppressor/cytotoxic T-cells and Natural Killer, NK, cells), NCR1 (NK cells), CD20 (B-cells), CD45 (nucleated hematopoietic cells), CD56 (NK and T-cells), CD68 (macrophages/monocytes) and CD83 (mature dendritic cells). The degree of scarring was assessed histologically using cross-polarized light to visualize collagen fibres. Scarring, regardless of clinical inflammation, was associated with increased inflammatory cell infiltrates on H&E and CD45 staining. Scarring was also associated with increased CD8+ and CD56+ cells, but not CD3+ cells, suggestive of a NK cell infiltrate. This was supported by the presence of NCR1+ cells. There was some increase in CD20+ cells, but no evidence for increased CD4+, CD68+ or CD83+ cells. Numerous CD45 negative cells were also seen in the population of infiltrating inflammatory cells in scarred conjunctiva. Disorganization of the normal collagen architecture was strongly associated with clinical scarring. These data point to the infiltration of immune cells with a phenotype suggestive of NK cells in conjunctival trachomatous scarring. A large proportion of CD45 negative inflammatory cells were also present. Future work should

    A previous study has shown that in age-related macular degeneration a high degree of concordance of disciform scar size occurs in the two eyes of any one patient. In a study of 35 patients with choroidal neovascular membrane who were treated with low dose ionising radiation to the macula of the affected eye, 11 were found to have bilateral disease. The visual outcome and scar size and morphology in the two eyes of each of these patients were compared. This study has provided evidence in support of reduced scarring and maintenance of better central visual function in radiotherapy treated eyes when compared with untreated fellow eyes. (author).

  18. A Case of Multiple Spontaneous Keloid Scars

    2015-07-01

    Full Text Available Keloid scars result from an abnormal healing response to cutaneous injury or inflammation that extends beyond the borders of the original wound. Spontaneous keloid scars forming in the absence of any previous trauma or surgical procedure are rare. Certain syndromes have been associated with this phenomenon, and few reports have discussed the evidence of single spontaneous keloid scar, which raises the question whether they are really spontaneous. Here, we present a 27-year-old mentally retarded single female with orbital hypertelorism, broad nasal bridge, repaired cleft lip and high-arched palate who presented with progressive multiple spontaneous keloid scars in different parts of her body which were confirmed histologically by the presence of typical keloidal collagen. This report supports the fact that keloid scars can appear spontaneously and are possibly linked to a genetic factor. Furthermore, it describes a new presentation of spontaneous keloid scars in the form of multiple large lesions in different sites of the body.

    Thermal injuries affect 250,000 people annually in the United Kingdom. As burn survival improves, good scar management is paramount to help individuals living with the resultant scars lead a life without restrictions. Post-burn hypertrophic scars can limit growth in children, interfere with function and cause psychological problems. In the current literature there is great variation in post-burn scar management across the world and in the evidence available for the efficacy of these management modalities. The aim of this study was to investigate the variances if any, in the management of post-burn scarring in children across the UK. A telephone survey of UK paediatric burn services was conducted to obtain information on post-burn scar management and advice given to patients/carers. Of the 19 burn services that participated, all advised moisturising of scars but with variable emphasis on massaging. Silicones and pressure therapy were used by 18 services but commencement of use varied from soon after healing to onset of hypertrophic scarring. Laser therapy, ultrasound therapy and steroid therapy were used sporadically. This study highlights the common modalities of post-burn scar management in children across the UK. However, there is marked variation in timing and selection of the commonly used modalities. Although this study did not investigate the outcomes of scar management, it clearly identifies the need for a well-designed multi-centred study to establish evidence-based best practice in the management of post-burn scarring in children as these modalities are time consuming and not without potential complications. Evidence based practice could potentially lead to significant financial savings to the health service. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Animal models provide a way to investigate scar therapies in a controlled environment. It is necessary to produce uniform, reproducible scars with high anatomic and biologic similarity to human scars to better evaluate the efficacy of treatment strategies and to develop new treatments. In this study, scar development and maturation were assessed in a porcine full-thickness burn model with immediate excision and split-thickness autograft coverage. Red Duroc pigs were treated with split-thickness autografts of varying thickness: 0.026in. ("thin") or 0.058in. ("thick"). Additionally, the thin skin grafts were meshed and expanded at 1:1.5 or 1:4 to evaluate the role of skin expansion in scar formation. Overall, the burn-excise-autograft model resulted in thick, raised scars. Treatment with thick split-thickness skin grafts resulted in less contraction and reduced scarring as well as improved biomechanics. Thin skin autograft expansion at a 1:4 ratio tended to result in scars that contracted more with increased scar height compared to the 1:1.5 expansion ratio. All treatment groups showed Matrix Metalloproteinase 2 (MMP2) and Transforming Growth Factor β1 (TGF-β1) expression that increased over time and peaked 4 weeks after grafting. Burns treated with thick split-thickness grafts showed decreased expression of pro-inflammatory genes 1 week after grafting, including insulin-like growth factor 1 (IGF-1) and TGF-β1, compared to wounds treated with thin split-thickness grafts. Overall, the burn-excise-autograft model using split-thickness autograft meshed and expanded to 1:1.5 or 1:4, resulted in thick, raised scars similar in appearance and structure to human hypertrophic scars. This model can be used in future studies to study burn treatment outcomes and new therapies. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

    Tumors that develop in old burn scars are usually squamous cell carcinomas. Sarcomas have also been reported, albeit rarely. To our knowledge, there has been only one case report of an extraskeletal osteosarcoma arising in a prior burn scar reported in the English-language literature, mainly discussing the clinicopathological features. Herein, we present a case of cutaneous osteosarcoma visualized as a mineralized soft-tissue mass arising from the scar associated with a previous skin burn over the back. This seems to be the first report describing the imaging features of a cutaneous osteosarcoma from an old burn scar. (orig.)

    Full Text Available Triterpenes are demonstrably effective for accelerating re-epithelialisation of wounds and known to improve scar formation for superficial lesions. Among the variety of triterpenes, betuline is of particular medical interest. Topical betuline gel (TBG received drug approval in 2016 from the European Commission as the first topical therapeutic agent with the proven clinical benefit of accelerating wound healing. Two self-conducted randomized intra-individual comparison clinical studies with a total of 220 patients involved in TBG treatment of skin graft surgical wounds have been screened for data concerning the aesthetic aspect of wound healing. Three months after surgery wound treatment with TBG resulted in about 30% of cases with more discreet scars, and standard of care in about 10%. Patients themselves appreciate the results of TBG after 3 months even more (about 50% compared to standard of care (about 10%. One year after surgery, the superiority of TBG counts for about 25% in comparison with about 10%, and from the patients’ point of view, for 25% compared to 4% under standard of care. In the majority of wound treatment cases, there is no difference visible between TBG treatment and standard of care after 1 year of scar formation. However, in comparison, TBG still offers a better chance for discreet scars and therefore happens to be superior in good care of wounds.

  5. Early cessation of pressure garment therapy results in scar contraction and thickening.

    Directory of Open Access Journals (Sweden)

    Danielle M DeBruler

    Full Text Available Pressure garment therapy is often prescribed to improve scar properties following full-thickness burn injuries. Pressure garment therapy is generally recommended for long periods of time following injury (1-2 years, though it is plagued by extremely low patient compliance. The goal of this study was to examine the effects of early cessation of pressure garment therapy on scar properties. Full-thickness burn injuries were created along the dorsum of red Duroc pigs. The burn eschar was excised and wound sites autografted with split-thickness skin. Scars were treated with pressure garments within 1 week of injury and pressure was maintained for either 29 weeks (continuous pressure or for 17 weeks followed by cessation of pressure for an additional 12 weeks (pressure released; scars receiving no treatment served as controls. Scars that underwent pressure garment therapy were significantly smoother and less contracted with decreased scar height compared to control scars at 17 weeks. These benefits were maintained in the continuous pressure group until week 29. In the pressure released group, grafts significantly contracted and became more raised, harder and rougher after the therapy was discontinued. Pressure cessation also resulted in large changes in collagen fiber orientation and increases in collagen fiber thickness. The results suggest that pressure garment therapy effectively improves scar properties following severe burn injury; however, early cessation of the therapy results in substantial loss of these improvements.

    Full Text Available Background Skin injuries, such as lacerations due to trauma, are relatively common, andpatients are very concerned about the resulting scars. Recently, the use of ablative and nonablativelasers based on the fractional approach has been used to treat scars. In this study,the authors demonstrated the efficacy and safety of ablative fractional resurfacing (AFRfor traumatic scars using a 2,940-nm erbium: yttrium-aluminum-garnet (Er:YAG laser fortraumatic scars after primary repair during the early posttraumatic period.Methods Twelve patients with fifteen scars were enrolled. All had a history of faciallaceration and primary repair by suturing on the day of trauma. Laser therapy was initiatedat least 4 weeks after the primary repair. Each patient was treated four times at 1-monthintervals with a fractional ablative 2,940-nm Er:YAG laser using the same parameters. Posttreatmentevaluations were performed 1 month after the fourth treatment session.Results All 12 patients completed the study. After ablative fractional laser treatment, alltreated portions of the scars showed improvements, as demonstrated by the VancouverScar Scale and the overall cosmetic scale as evaluated by 10 independent physicians, 10independent non-physicians, and the patients themselves.Conclusions This study shows that ablative fractional Er:YAG laser treatment of scars reducesscars fairly according to both objective results and patient satisfaction rates. The authorssuggest that early scar treatment using AFR can be one adjuvant scar management methodfor improving the quality of life of patients with traumatic scars.

    Full Text Available Objectives. Several modalities have been advocated to treat traumatic scars, including surgical techniques and laser resurfacing. Recently, a plasma skin regeneration (PSR system has been investigated. There are no reports on plasma treatment of mesh skin grafted scars. The objective of our study is to evaluate the effectiveness and complications of plasma treatment of mesh skin grafted scars in Asian patients. Materials and Methods. Four Asian patients with mesh skin grafted scars were enrolled in the study. The plasma treatments were performed at monthly intervals with PSR, using energy settings of 3 to 4 J. Improvement was determined by patient questionnaires and physician evaluation of digital photographs taken prior to treatment and at 3 months post treatment. The patients were also evaluated for any side effects from the treatment. Results. All patients showed more than 50% improvement. The average pain score on a 10-point scale was 6.9 +/− 1.2 SD and all patients tolerated the treatments. Temporary, localized hypopigmentation was observed in two patients. Hyperpigmentation and worsening of scarring were not observed. Conclusions. Plasma treatment is clinically effective and is associated with minimal complications when used to treat mesh skin grafted scars in Asian patients.

    The purpose of this study was to evaluate helical tomotherapy dosimetry in postmastectomy patients undergoing treatment for chest wall and positive nodal regions with simultaneous integrated boost (SIB) in the scar region using strip bolus. Six postmastectomy patients were scanned with a 5-mm-thick strip bolus covering the scar planning target volume (PTV) plus 2-cm margin. For all 6 cases, the chest wall received a total cumulative dose of 49.3–50.4 Gy with daily fraction size of 1.7–2.0 Gy. Total dose to the scar PTV was prescribed to 58.0–60.2 Gy at 2.0–2.5 Gy per fraction. The supraclavicular PTV and mammary nodal PTV received 1.7–1.9 dose per fraction. Two plans (with and without bolus) were generated for all 6 cases. To generate no-bolus plans, strip bolus was contoured and overrode to air density before planning. The setup reproducibility and delivered dose accuracy were evaluated for all 6 cases. Dose-volume histograms were used to evaluate dose-volume coverage of targets and critical structures. We observed reduced air cavities with the strip bolus setup compared with what we normally see with the full bolus. The thermoluminescence dosimeters (TLD) in vivo dosimetry confirmed accurate dose delivery beneath the bolus. The verification plans performed on the first day megavoltage computed tomography (MVCT) image verified that the daily setup and overall dose delivery was within 2% accuracy compared with the planned dose. The hotspot of the scar PTV in no-bolus plans was 111.4% of the prescribed dose averaged over 6 cases compared with 106.6% with strip bolus. With a strip bolus only covering the postmastectomy scar region, we observed increased dose uniformity to the scar PTV, higher setup reproducibility, and accurate dose delivered beneath the bolus. This study demonstrates the feasibility of using a strip bolus over the scar using tomotherapy for SIB dosimetry in postmastectomy treatments.

  16. SCAR/WAVE: A complex issue.

    Davidson, Andrew J; Insall, Robert H

    2013-11-01

    The SCAR/WAVE complex drives the actin polymerisation that underlies protrusion of the front of the cell and thus drives migration. However, it is not understood how the activity of SCAR/WAVE is regulated to generate the infinite range of cellular shape changes observed during cell motility. What are the relative roles of the subunits of the SCAR/WAVE complex? What signaling molecules do they interact with? And how does the complex integrate all this information in order to control the temporal and spatial polymerisation of actin during protrusion formation? Unfortunately, the interdependence of SCAR complex members has made genetic dissection hard. In our recent paper,(1) we describe stabilization of the Dictyostelium SCAR complex by a small fragment of Abi. Here we summarize the main findings and discuss how this approach can help reveal the inner workings of this impenetrable complex.

    We discover and characterise strong quantum scars, or quantum eigenstates resembling classical periodic orbits, in two-dimensional quantum wells perturbed by local impurities. These scars are not explained by ordinary scar theory, which would require the existence of short, moderately unstable periodic orbits in the perturbed system. Instead, they are supported by classical resonances in the unperturbed system and the resulting quantum near-degeneracy. Even in the case of a large number of randomly scattered impurities, the scars prefer distinct orientations that extremise the overlap with the impurities. We demonstrate that these preferred orientations can be used for highly efficient transport of quantum wave packets across the perturbed potential landscape. Assisted by the scars, wave-packet recurrences are significantly stronger than in the unperturbed system. Together with the controllability of the preferred orientations, this property may be very useful for quantum transport applications.

    The aim of this study is to compare Tuberculin Skin Test (TST) result and interferon gamma response to human PPD (purified protein derivative), in scar positive and scar negative BCG-vaccinated children. Between August 2007 and May 2008 a total of 236 children aged 1-168 months (mean 21 months) admitted to Mofid Children's Hospital, Tehran, Iran, were enrolled in a cross-sectional study. Each patient was examined for BCG vaccine scar and tested with TST and human PPD-based Interferon Gamma Release Assay (IGRA). Two hundred and twenty one cases out of 236 (44% female, 1-168 months, mean age 21 months) were scar positive of whom 95% TST result was negative. Human PPD-based IGRA was positive in 110 (49.8%), negative in 85 (38.4 %) and indeterminate in 26 (11.8%) of scar positive patients. Fifteen children (40% female, 1-156 months; mean age 42 months) were scar negative. All the scar negative cases were TST negative. Human PPD-based IGRA was positive in 10 (66.7%), negative in 4 (26.7%) and indeterminate in 1 (6.7%) of scar negative patients. Immune responsiveness to human PPD antigens in scar positive and negative children may not correspond with results of the Tuberculin Skin Test. Copyright © 2013 Ministry of Health, Saudi Arabia.

    Objective: Acute pyelonephritis (APN) is a common infectious disease in childhood. APN may result in ineversible renal scarring. 99 Tc m -dimercaptsuccinic (DMSA) renal cortical scintigraphy was reported to be highly sensitive and specific for detection APN and renal scarring. The aim of this study was to determine the incidence of renal scarring in a group of children with APN and to evaluate the relative factors at risk of scarring using 99 Tc m -DMSA renal cortical scintigraphy. Methods: One hundred and eighteen patients (44 males, 74 females, age range: 1 month to 14 years) with APN underwent DMSA renal cortical scan before treatment and six month after treatment to identify renal damage and renal scarring. The degree of renal damage was divided to grade I to IV. A directed radionuclide cystography (DRC) was performed in 72 cases to evaluate vesicoureteric reflux (VUR). Statistical analysis between all those relative factors was performed using Spearman grading relational analysis. The software was SPSS 11.5. Results: The follow-up renal cortical scan revealed that 79 normal kidneys on first scan remained normal; of 64 kidneys with grade I damage, 7.81% (5/64) developed renal scar; of 51 kidneys with grade II, 49.02% (25/51) developed renal scar; of 19 with grade III, 68.42% (13/19) developed renal scar; of 23 with grade IV, 100.00% (23/23) developed renal scar. There was a significant relationship between the incidence of renal scar on follow-up and the grade of renal damage on first scan (r=0.877, P<0.01). VUR was found in 54.17% (78/144) per renal unit. Only 4.55% (3/66) of those with non-refluxing ureters developed renal scars on follow-up. One of four patients with mild-refluxing ureters developed renal scars. 46.51% (20/43) of those with moderate-refluxing ureters developed renal scars. 87.10% (27/31) of those with severe-refluxing ureters developed renal scars. There was a significant relationship between the incidence of renal scarring in follow-up and

    Gynecomastia is a benign, excessive development of the male breast that occurs at an overall incidence of 32-36 %. The authors effectively removed peripheral fat tissues with power-assisted liposuction (PAL) and periareolar glandular tissues with a cartilage shaver in a series of patients. The small periareolar incisions were not easily recognized. Between February 2010 and April 2012, the charts of 15 patients (28 breasts) treated with PAL and a cartilage shaver were retrospectively reviewed. The mean volume of fat tissue removed with liposuction was 319 mL, and the mean volume of glandular tissue removed with the cartilage shaver was 70 mL. The mean follow-up period was 11.2 months. No infection, nipple-areola complex necrosis, nipple retraction, or saucer deformity was encountered in this series. Intraoperative bleeding occurred in one patient. Mild asymmetries developed in three patients. Use of PAL and a cartilage shaver for the treatment of gynecomastia allows for effective removal of both the fat and the glandular tissue of the breast through a minimal periareolar incision. This technique can achieve excellent aesthetic results with inconspicuous scarring. This journal requires that authors assign a level of evidence to each article.

    Late enhancement cardiac magnetic resonance images (MRI) has the ability to precisely delineate myocardial scars. We present a semi-automated method for detecting scars in cardiac MRI. This model has the potential to improve routine clinical practice since quantification is not currently offered due to time constraints. A first segmentation step was developed for extracting the target regions for potential scar and determining pre-candidate objects. Pattern recognition methods are then applied to the segmented images in order to detect the position of the myocardial scar. The database of late gadolinium enhancement (LE) cardiac MR images consists of 111 blocks of images acquired from 63 patients at the University Hospital Southampton NHS Foundation Trust (UK). At least one scar was present for each patient, and all the scars were manually annotated by an expert. A group of images (around one third of the entire set) was used for training the system which was subsequently tested on all the remaining images. Four different classifiers were trained (Support Vector Machine (SVM), k-nearest neighbor (KNN), Bayesian and feed-forward neural network) and their performance was evaluated by using Free response Receiver Operating Characteristic (FROC) analysis. Feature selection was implemented for analyzing the importance of the various features. The segmentation method proposed allowed the region affected by the scar to be extracted correctly in 96% of the blocks of images. The SVM was shown to be the best classifier for our task, and our system reached an overall sensitivity of 80% with less than 7 false positives per patient. The method we present provides an effective tool for detection of scars on cardiac MRI. This may be of value in clinical practice by permitting routine reporting of scar quantification.

    Radial scars are getting more and more common since implementation of mammography as diagnostic tool in screening women for breast cancer. At Karolinska Hospital, 18987 asymptomatic women, aged 50-69, were screened for breast cancer through mammography during August 1989-May 1991. A total of 735 (3.87%) were recalled for additional views after initial mammograms and 463 (2.44%) were assessed with help of cytology. In all 175 women (0.92%) were selected for surgery and 146 (0.77%) had histologically verified cancers. The remaining 29 (0.15%) had non- malignant lesions of which 11 (0.06%) were radial scars. All radial scars were diagnosed on mammograms and later confirmed with histology. The radiologic characteristics were found to be a) rather thick and long radiating structures accompanied by radiolucent linear structures parallel to some of the spicules, b) absence of calcifications, c) radiolucent areas in the body of the lesion, d) an average mean size of 6 mm and e) changing image in different views. Most of the lesions, 73% (8/11), were in moderately dense breasts and there was no specific relation to the right or left breast. A majority of radial scars, 64% (7/11), were found in the upper outer quadrants, 3/11 in the lower outer quadrants and 1/11 in the lower inner quadrant. Literature shows that histology uses many synonyms for radial scars and therefore team work between radiologists and pathologists is suggested for better conformity of the diagnosis.

    Vocal fold scar and sulcus are intractable diseases with no effective established treatments. Hepatocyte growth factor (HGF) has preclinically proven to have potent antifibrotic and regenerative effects on vocal fold scar. The current Phase I/II clinical trial aims to examine the safety and effectiveness of intracordal injection of a recombinant human HGF drug for patients with vocal fold scar or sulcus. This is an open-label, dose-escalating, first-in-human clinical trial. Eighteen patients with bilateral vocal fold scar or sulcus were enrolled and divided into three groups: Step I received 1 μg of HGF per vocal fold; Step II received 3 μg of HGF; and Step III received 10 μg of HGF. Injections were administered once weekly for 4 weeks. The protocol treatment was performed starting with Step I and escalating to Step III. Patients were followed for 6 months post-treatment. Local and systemic safety aspects were examined as primary endpoints, and therapeutic effects were assessed as secondary endpoints using voice handicap index-10; maximum phonation time; vocal fold vibratory amplitude; grade, rough, breathy, asthenic, strained scale; and jitter. The results indicated no serious drug-related adverse events in either the systemic or local examinations. In whole-subject analysis, voice handicap index-10, vocal fold vibratory amplitude, and grade, rough, breathy, asthenic, strained scale were significantly improved at 6 months, whereas maximum phonation time and jitter varied. There were no significant differences in phonatory data between the step groups. In conclusion, intracordal injection of a recombinant human HGF drug was safe, feasible, and potentially effective for human patients with vocal fold scar or sulcus.

    The present study aimed to investigate the diagnostic value of fragmented QRS complex (fQRS) on 12-lead electrocardiogram (ECG) for myocardial scar detection, and presented the results in a systematic review and meta-analysis format. Medline, SCOPUS, and ISI Web of Knowledge were searched electronically with "Fragmented QRS" or "fQRS" as key words. All related studies that had evaluated the accuracy of fQRS for myocardial scar diagnosis were included. Eight studies (2560 patients) were finally included in the systematic review. Specificity assessment could be evaluated only by five out of these eight articles. Overall pooled sensitivity of fQRS, Q wave, and mixed Q-fQRS was 68% (65-71), 51% (47-55), and 74% (69-79) and the pooled specificity was 80% (79-81), 97% (97-98) and 92% (91-93), respectively. Fragmented QRS is a novel ECG marker with more sensitivity and less specificity than Q wave. A combination of fQRS with Q wave in a 12-lead ECG results in up to 74% sensitivity and 92% specificity. Additional studies are needed to assess the significance of this ECG parameter for regional myocardial scar detection.

    Full Text Available We present a new preclinical model to study treatment, resolution and sequelae of severe ascending pyelonephritis. Urinary tract infection (UTI, primarily caused by uropathogenic Escherichia coli (UPEC, is a common disease in children. Severe pyelonephritis is the primary cause of acquired renal scarring in childhood, which may eventually lead to hypertension and chronic kidney disease in a small but important fraction of patients. Preclinical modeling of UTI utilizes almost exclusively females, which (in most mouse strains exhibit inherent resistance to severe ascending kidney infection; consequently, no existing preclinical model has assessed the consequences of recovery from pyelonephritis following antibiotic treatment. We recently published a novel mini-surgical bladder inoculation technique, with which male C3H/HeN mice develop robust ascending pyelonephritis, highly prevalent renal abscesses and evidence of fibrosis. Here, we devised and optimized an antibiotic treatment strategy within this male model to more closely reflect the clinical course of pyelonephritis. A 5-day ceftriaxone regimen initiated at the onset of abscess development achieved resolution of bladder and kidney infection. A minority of treated mice displayed persistent histological abscess at the end of treatment, despite microbiological cure of pyelonephritis; a matching fraction of mice 1 month later exhibited renal scars featuring fibrosis and ongoing inflammatory infiltrates. Successful antibiotic treatment preserved renal function in almost all infected mice, as assessed by biochemical markers 1 and 5 months post-treatment; hydronephrosis was observed as a late effect of treated pyelonephritis. An occasional mouse developed chronic kidney disease, generally reflecting the incidence of this late sequela in humans. In total, this model offers a platform to study the molecular pathogenesis of pyelonephritis, response to antibiotic therapy and emergence of sequelae

      Acne scars can cause emotional and psychosocial disturbance to the patient. Various modalities have been used for the treatment of acne scars like punch excision, subcision, peels, microdermabrasion, unfractionated and fractioned lasers. The latest in the treatment armamentarium is microneedling. Acne scars commonly coexist with postinflammatory hyperpigmentation. A combination of microneedling and glycolic acid (GA) peels was found to give excellent results in the treatment of such scars. The aim was to study the efficacy of a combination of microneedling with glycolic peel for the treatment of acne scars in pigmented skin.   Thirty patients in the age group of 20-40 years with atrophic box type or rolling scars with postinflammatory hyperpigmentation were chosen for the study. Two groups were made. The first group comprised of 30 patients in whom only microneedling was performed once in 6 weeks for five sessions. In the second group of 30 patients, a combination of microneedling and 35% GA peels was carried out. Patients from both groups were evaluated on the basis of Echelle d'Evaluation clinique des Cicatrices d'acné classification.   Based on the objective scoring and its statistical analysis, there was significant improvement in superficial and moderately deep scars (grade 1-3). There was also improvement in skin texture, reduction in postacne pigmentation in the second group.   Microneedling is a simple, inexpensive office procedure with no downtime. It is safe in Indian skin (skin types III-IV). The combined sequential treatment with GA peel caused a significant improvement in the acne scars without increasing morbidity. © 2011 Wiley Periodicals, Inc.

    Full Text Available BACKGROUND Caesarean section (Sectio Caesarea is a surgical method for the completion of delivery. After various historical modifications of operative techniques, modern approach consists in the transverse dissection of the anterior wall of the uterus. The rate of vaginal birth after caesarean section was significantly reduced from year to year and the rate of repeated caesarean section is increased during the past 10 years. Evaluation of scar thickness is done by ultrasound, but it is still debatable size of thick scar that would be guiding “cut-off value” for the completion of the delivery method. To better assess the risk of uterine rupture, some authors have proposed sonographic measurement of lower uterine segment thickness near term assuming that there is an inverse correlation between LUS thickness and the risk of uterine scar defect. Therefore, this assessment for the management of women with prior CS may increase safety during labour by selecting women with the lowest risk of uterine rupture. The aim of the study is to study the diagnostic accuracy of sonographic measurements of the Lower Uterine Segment (LUS thickness near term in predicting uterine scar defects in women with prior Caesarean Section (CS. We aim to ascertain the best cut-off values for predicting uterine rupture. MATERIALS AND METHODS 100 antenatal women with history of previous one LSCS who come to attend antenatal clinic will be assessed for scar thickness by transabdominal ultrasonography and its correlation with intraoperative findings. This prospective longitudinal study was conducted for 1 year after IEC approval with inclusion criteria previous one LSCS. Exclusion criteria- 1 Previous myomectomy scar; 2 Previous 2 LSCS; 3 Previous hysterotomy scar. RESULTS Our findings indicate that there is a strong association between degree of LUS thinning measured near term and the risk of uterine scar defect at birth. In our study, optimal cut-off value for predicting

    Full Text Available Background. Marjolin’s ulcer is a rare, aggressive cutaneous malignancy that arises primarily in burn scars but can occur in other types of scars. Squamous cell carcinoma is the most common variant, and while malignant degeneration usually takes a long time, it can develop acutely. Case Report. a 30-year-old man who developed Marjolin’s ulcer acutely in a right postauricular scar after mastoidectomy and the incision and drainage of a mastoid abscess. To the best of our knowledge, this report is the first to describe a Marjolin’s ulcer in a postauricular surgical scar. However, it has been reported in others areas in the head and neck. Conclusion. Marjolin’s ulcer is most commonly observed after postburn scars, but it may be observed after any type of scars, as our patient developed an SCC with a postsurgical scar. Early diagnosis is essential, and a biopsy should be performed on any nonhealing wound or chronic wound that undergoes a sudden change. Tissue samples should be taken from both the centre and the margins of the wound.

    This study explored the feasibility and clinical efficacy of expanded flap to repair facial scar left by radiotherapy of hemangioma. From March 2000 to April 2011, 13 cases of facial cicatrices left by radiotherapy of hemangioma have been treated with implantation surgery of facial skin dilator under local anesthesia. After water flood expansion for 1-2 months, resection of facial scar was performed, and wound repairing with expansion flap transfer was done. Thirteen patients were followed up from 5 months to 3 years. All patients tolerated flap transfer well; no contracture occurred during the facial expansion flap transfer. The incision scar was not obvious, and its color and texture were identical to surrounding skin. In conclusion, the use of expanded flap transfer to repair the facial scar left by radiotherapy of hemangioma is advantageous due to its simplicity, flexibility, and large area of repairing. This method does not affect the subsequent facial appearance.

They constituted about 50% of all patients admitted with local recurrence from melanoma during this period....... At reexamination of the primary tumors, 16 were found to be malignant melanomas and 9 were nevi (four atypical and five benign). Twenty-one were missing, 11 of which had never been set for histologic examination. The median thickness of nine measurable melanomas was 0.66 mm. The recurrences in scar consisted of 34...... recurrences in the form of a new primary in a scar following limited surgery supports the theory of limited field change around a primary melanoma. Furthermore, limited procedures for primary melanoma, if followed by a recurrence in the scar, worsen the prognosis....

    Conclusion: Patients with IC/BPS may be severely debilitated by a clinically significant decrease in their bladder capacity, especially in the face of HL. The use of the holmium laser to incise regions of scar and bladder wall tethering may produce a clinically significant and durable increase in bladder capacity. The use of this technique as a means of treating bladder scarring poses an excellent adjunct to existing treatment strategies.

    Simple Summary Organizations responsible for placing dogs seized from dogfighting investigations often must determine if a particular dog should be euthanized because it is too dangerous or if it is safe to place the dog in an adoptive home. In this study, we examine whether the extent of scarring from dog fighting is a reliable predictor of aggression towards other dogs and therefore could be used to help make that decision. We found that dogs with 10 or more scars in the three body zones where dogfighting injuries tend to be concentrated were more likely, on average, to show aggression to other dogs. The relationship is imperfect, however. Many unscarred dogs were dog aggressive while some highly scarred dogs were not. Therefore, we recommend also assessing a dog’s behavior before making decisions about its disposition. Abstract When pit bull-type dogs are seized in an investigation of organized dogfighting, heavily scarred dogs are often assumed to be highly dog aggressive due to a history of fighting. These dogs may be deemed dangerous and euthanized based on scarring alone. We analyzed our existing data on dogs seized from four dogfighting investigations, examining the relationship between the dogs’ scars with aggression towards other dogs. Scar and wound data were tallied in three body zones where dogfighting injuries tend to be concentrated. Dog aggression was assessed using a model dog and a friendly stimulus dog in a standardized behavior evaluation. Scarring and dog aggression were significantly related, more strongly among male (Fisher’s Exact p < 0.001) than female dogs (Fisher’s Exact p = 0.05). Ten or more scars in the three body zones was a reasonable threshold with which to classify a dog as high risk for dog aggression: 82% of males and 60% of females with such scarring displayed dog aggression. However, because many unscarred dogs were dog aggressive while some highly scarred dogs were not, we recommend collecting behavioral information to

    Objective: To assess the clinical value of uterine arterial embolization (UAE) in treating uterine scar pregnancy after cesarean section. Methods: A total of' 35 cases with cesarean scar pregnancy, admitted to authors' hospital during the period from Jan. 2007 to June 2011, were divided into two groups: embolization group (n=21) and non-embolization group (n=14). By using Seldinger technique, UAE was performed via the right femoral access and gelatin sponge particle was used as embolization agent to occlude the uterine artery. In embolization group, sixteen patients received uterine cavity curettage one or two days after UAE, while five patients received laparotomy or perineotomy surgery to remove the lesions after UAE. In non-embolization group, uterine cavity curettage was performed directly in 8 patients, local injection of' methotrexate followed by uterine cavity curettage was carried out in 3 patients, and direct laparotomy to remove the lesions was adopted in the remaining 3 patients. The blood loss during the procedure, the hospitalization days and the time for β-HCG levels falling to normal were documented. The results were compared between the two groups. Results: UAE was successfully accomplished in all the 21 patients of embolization group and the uterus was preserved in all patients. For the embolization group, the mean hospitalization time was (11.5±3.6) days, and the time for β-HCG levels falling to normal was (18.6±4.9) days. For the non-embolization group, the mean hospitalization time was(20.4±5.2)days, and the time for β-HCG levels falling to normal was (28.7±5.6)days. Hysterectomy had to be carried out in two patients of non-embolization group due to the massive bleeding occurred in therapeutic procedures. Conclusion: For the treatment of cesarean scar pregnancy, UAE is very effective and mini-invasive with high success rate. UAE can preserve the patient's reproductive function, and it also plays a significant role in preventing hemorrhage

    To investigate the effectiveness of dorsal metacarpal island flap for treating scar contracture of the finger web. Between June 2009 and December 2010, 10 patients with scar contracture of the finger web were treated. There were 6 males and 4 females with an average age of 30 years (range, 14-57 years). Scar contracture was caused by injury in 8 cases, by burn in 1 case, and by operation in 1 case. The locations were the 1st web space in 1 case, the 2nd web space in 3 cases, the 3rd web space in 5 cases, and the 4th web space in 1 case. The disease duration was 3 to 9 months with an average of 5 months. The maximum abduction was 10-20 degrees. After web space scar release, the dorsal metacarpal island flap (3.5 cm x 1.2 cm-4.0 cm x 2.0 cm in size) was used to reconstruct web space (2.0 cm x 1.0 cm-3.0 cm x 1.8 cm in size). The donor site was directly sutured or repaired with local flaps. At 2 days after operation, necrosis occurred in 1 flap, which healed by extractive treatment. The other flaps survived and wound healed by first intention; all the flaps at donor sites survived and incision healed by first intention. Ten patients were followed up 6 to 15 months (mean, 9 months). The reconstructed web space had good appearance, the maximum abduction was 80 degrees in 1 case of the 1st web space scars contracture, and the maximum abduction was 35-45 degrees (mean, 40 degrees) in the other 9 cases. In 8 scar patients causing by injury, no scar contracture recurred during follow-up. It can achieve good results in appearance and function to use dorsal metacarpal island flap for treating scar contracture of the finger web.

    Hypertrophic scarring (HS) is an overcompensation of wound healing that increases the risk of cosmetic disfigurement and functional impairment. No gold standard has been established for the treatment or prevention of HS. Our study aims to elucidate the expression and function of lumican in the pathogenesis of HS as well as the underlying mechanism involved in this procedure. An animal model of HS (rabbit ear) was established, and the Ad-lumican vectors were locally injected. Primary fibroblasts isolated from patients with hypertrophic burn scars were used in vitro. Histological and molecular changes in HS pathogenesis were evaluated. The results showed that lumican is significantly reduced in HS tissues and fibroblasts from HS patients as compared to normal skin or cells. Lumican levels were further suppressed in response to TGF-β stimulation. However, lumican upregulation effectively thinned the scar area and inhibited fibroblast proliferation and the cell cycle. Meanwhile, Ad-lumican administration suppressed the deposition of extracellular matrix, such as collagen and CTGF. Ad-lumican injected animals or fibroblasts presented comparable integrin α 2 β 1 expression while greatly reduced phosphorylation of FAK compared to the negative control. Moreover, Ad-lumican administration largely enhanced the binding of lumican to integrin α 2 β 1 and may thus inhibit the signaling propagation of collagen-integrin α 2 β 1 . Overall, the restoration of lumican levels contributed to suppressing the HS progression by inhibiting collagen-integrin α 2 β 1 -FAK signaling. - Highlights: • Lumican is downregulated during hypertrophic scar formation. • Lumican inhibits fibroblast proliferation. • Lumican inhibits extracellular matrix deposition. • Lumican suppresses collagen-integrin-FAK signaling.

    Although it is known that Anderson-Fabry Disease (AFD) can mimic the morphologic manifestations of hypertrophic cardiomyopathy (HCM) on echocardiography, there is a lack of cardiovascular magnetic resonance (CMR) literature on this. There is limited information in the published literature on the distribution of myocardial fibrosis in patients with AFD, with scar reported principally in the basal inferolateral midwall. All patients with confirmed AFD undergoing CMR at our center were included. Left ventricular (LV) volumes, wall thicknesses and scar were analyzed offline. Patients were categorized into 4 groups: (1) no wall thickening; (2) concentric hypertrophy; (3) asymmetric septal hypertrophy (ASH); and (4) apical hypertrophy. Charts were reviewed for clinical information. Thirty-nine patients were included (20 males [51%], median age 45.2 years [range 22.3-64.4]). Almost half (17/39) had concentric wall thickening. Almost half (17/39) had pathologic LV scar; three quarters of these (13/17) had typical inferolateral midwall scar. A quarter (9/39) had both concentric wall thickening and typical inferolateral scar. A subgroup with ASH and apical hypertrophy (n = 5) had greater maximum wall thickness, total LV scar, apical scar and mid-ventricular scar than those with concentric hypertrophy (n = 17, p < 0.05). Patients with elevated LVMI had more overall arrhythmia (p = 0.007) more ventricular arrhythmia (p = 0.007) and sustained ventricular tachycardia (p = 0.008). Concentric thickening and inferolateral mid-myocardial scar are the most common manifestations of AFD, but the spectrum includes cases morphologically identical to apical and ASH subtypes of HCM and these have more apical and mid-ventricular LV scar. Significant LVH is associated with ventricular arrhythmia.

    To investigate the incidence of port-site adhesions following use of radially expanding trocars (RETs) at laparoscopic myomectomy by observation via second-look laparoscopy (SLL). In a retrospective study, data from patients who underwent SLL after laparoscopic myomectomy between January 2007 and June 2012 at Juntendo University Hospital, Tokyo, were assessed for the incidence of port-site adhesions forming below RET incisional scars when fascial and peritoneal defects had not been closed. During the study period, 554 patients underwent SLL, and 2176 incisional scars were examined. Adhesions were detected in 15 patients (2.8%); thus, the incidence of port-site adhesions under scars was 0.7% (15/2176). Among these 15 patients, the wounds with adhesions were located as follows: 6 (1.1%) under the umbilical scar, 5 (0.9%) under the right lower abdominal scar, 2 (0.4%) under the left upper abdominal scar, and 2 (0.4%) under the left lower abdominal scar. According to multiple regression analysis, the duration of laparoscopic myomectomy was positively associated with port-site adhesions (odds ratio, 1.79; 95% confidence interval, 1.09-2.94; P=0.02). The present data suggest that the incidence of port-site hernias and adhesions under RET incisional scars is low despite the non-closure of fascial and peritoneal defects.

    The paper is concerned with a therapeutic method for hypertrophic scars inc cluding Bucky rays, pyrogenal, vitamins a, e, b 12 , sodium salicylate and dimexide ointment. Multimodality treatment of hypertrophic scars is effective, well tolerated and can be widely used in out-patient clinics. It makes it possible to reduce the period of therapy by 2-3 mos., and the summary dose by 20 000-3000 rad (18.6-27.9 Gy) as compared to common therapy with Wucky rays only Changes in the connective structure of scars in the process of multimodality th herapy are nonspecific and account for some mechanisms of scar regression and reaffirm the efficacy of this therapeutic method

    Urinary tract infections (UTIs) are common childhood bacterial infections that may involve renal parenchymal infection (acute pyelonephritis [APN]) followed by late scarring. Prompt, high-quality diagnosis of APN and later identification of children with scarring are important for preventing future complications. Examination via dimercaptosuccinic acid scanning is the current clinical gold standard but is not routinely performed. A more accessible assay could therefore prove useful. Our goal was to study procalcitonin as a predictor for both APN and scarring in children with UTI. A systematic review and meta-analysis of individual patient data were performed; all data were gathered from children with UTIs who had undergone both procalcitonin measurement and dimercaptosuccinic acid scanning. A total of 1011 patients (APN in 60.6%, late scarring in 25.7%) were included from 18 studies. Procalcitonin as a continuous, class, and binary variable was associated with APN and scarring (P children who had APN during the early stages of UTI, as well as those with late scarring.

    Vocal fold scar disrupts the mucosal wave and interferes with glottic closure. Treatment involves a multidisciplinary approach that includes voice therapy, medical management, and sometimes surgery. We reviewed the records of the first eight patients who underwent autologous fat implantation for vocal fold scar. Information on the etiology of scar, physical findings, and prior interventions were collected. Videotapes of videostroboscopic findings and perceptual voice ratings [Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS)] were randomized and analyzed independently by four blinded observers. Etiology of scar included mass excision (7), vocal fold stripping (3), congenital sulcus (2), and hemorrhage (1). Prior surgical procedures performed included thyroplasty (1), autologous fat injection (9), excision of scar (2), and lysis of adhesions (2). Strobovideolaryngoscopy: Statistically significant improvement was found in glottic closure, mucosal wave, and stiffness (P = 0.05). Perceptual ratings (GRBAS): Statistically significant improvement was found in all five parameters, including overall Grade, Roughness, Breathiness, Asthenia, and Strain (P = 0.05). Patients appear to have improved vocal fold function and quality of voice after autologous fat implantation in the vocal fold. Autologous fat implantation is an important adjunctive procedure in the management of vocal fold scar, and a useful addition to the armamentarium of the experienced phonomicrosurgeon.

    Fractional photothermolysis has been reported in the literature to improve pigmentary and textural changes associated with acne scarring. To review the literature for the treatment of acne scarring using nonablative fractional laser (NAFL) and ablative fractional laser (AFL) resurfacing. Review of the Medline literature evaluating NAFL and AFL for acne scarring. NAFL and AFL are safe and effective treatments for acne scarring. It is likely that the controlled, limited dermal heating of fractional resurfacing initiates a cascade of events in which normalization of the collagenesis-collagenolysis cycle occurs. We present the results of a patient treated using a novel dual-spot-size AFL device. Three months after the final treatment, the patient reported 75% improvement in acne scarring and 63% overall improvement in photoaging. Fractionated resurfacing for the treatment of acne scarring is associated with lesser risks of side effects of prolonged erythema and risks of delayed-onset dyspigmentation and scarring which complicate traditional ablative laser resurfacing approaches. We present herein preliminary data suggesting that a dual-spot-size AFL device presents novel advantages of improving texture and pigmentation in acne scarring and photoaging. © 2011 by the American Society for Dermatologic Surgery, Inc.

    A review of the following points was performed: Factors favouring the development and presence of malnutrition among hospitalized patients. Useful parameters in nutritional evaluation. Types of malnutrition. The Chang nutritional evaluation protocol is used in our Hospital, which is simple, inexpensive, reliable, specific and easily reproduced. This is based on five variables (three anthropometric and two biochemical), randomized and based on reference tables and values. A study was made on data corresponding to 70 patients, in whom a prevalence of malnutrition was observed in critical patients. The patients were classified based on three different definitive possibilities (Marasmo, Kwashiorkor and combined), and three grades of malnutrition (slight, moderate and severe).

    Full Text Available BackgroundSkin injuries, such as lacerations due to trauma, are relatively common, and patients are very concerned about the resulting scars. Recently, the use of ablative and non-ablative lasers based on the fractional approach has been used to treat scars. In this study, the authors demonstrated the efficacy and safety of ablative fractional resurfacing (AFR for traumatic scars using a 2,940-nm erbium: yttrium-aluminum-garnet (Er:YAG laser for traumatic scars after primary repair during the early posttraumatic period.MethodsTwelve patients with fifteen scars were enrolled. All had a history of facial laceration and primary repair by suturing on the day of trauma. Laser therapy was initiated at least 4 weeks after the primary repair. Each patient was treated four times at 1-month intervals with a fractional ablative 2,940-nm Er:YAG laser using the same parameters. Post-treatment evaluations were performed 1 month after the fourth treatment session.ResultsAll 12 patients completed the study. After ablative fractional laser treatment, all treated portions of the scars showed improvements, as demonstrated by the Vancouver Scar Scale and the overall cosmetic scale as evaluated by 10 independent physicians, 10 independent non-physicians, and the patients themselves.ConclusionsThis study shows that ablative fractional Er:YAG laser treatment of scars reduces scars fairly according to both objective results and patient satisfaction rates. The authors suggest that early scar treatment using AFR can be one adjuvant scar management method for improving the quality of life of patients with traumatic scars.

    Scar management is a recognised key component of rehabilitation following burn. Moisturising often combined with massage is commenced once healing tissue has gained sufficient strength to tolerate surface friction, with the aim being to hydrate the dry scar. The studies on various moisturisers and creams provide some guidance on moisturiser selection, but many are inconclusive. This survey aimed to determine the current expert opinion regarding moisturiser recommendations, including the basis for these recommendations, across the burns community. A brief web-based survey was distributed to burn therapists via mailing lists of the Australian and New Zealand Burn Association (ANZBA), and American Burn Association (ABA) 'Occupational and Physical Therapist Burn Special Interest Group'. The fifty three respondents indicated that there were 29 different moisturisers commonly recommended in practice. Three main themes were indicated as influencing recommendations for moisturiser: the perceived effects on the scar/skin (48%); the general properties of the moisturiser (38%); the ingredients (14%). Therapists reported that the principle stimuli determining their recommendations were patient feedback and the choice of the previous burn therapist in their service. Many were also guided by medical staff, pharmacists and sales representatives. Only three respondents were able to provide citations for published evidence supporting their recommendations. There is a paucity of evidence currently to support optimal moisturiser choice. This survey demonstrates that conflicting opinions are held on the ideal moisturiser brand, properties and ingredients. The recommendations made are based on low level evidence. Further research is required to inform clinicians which moisturiser to recommend to their clients. An ideal moisturiser should be one that is conducive to scar maturation, non- or minimally irritant, prevent skin drying, minimise transepidermal water loss and have no negative

    There is a paucity of studies on the use of chemical peels for acne scars among the Asian population. A trichloroacetic acid (TCA) and Jessner's combination chemical peel, originally described by Monheit, is said to be better than a TCA peel alone. The aim of the study was to compare the efficacy of 20% TCA and Jessner's solution versus 20% TCA alone for the treatment of acne scars. : The patients were divided into two groups of 25 patients each. Chemical peeling was done in both the groups. In Group I, chemical peeling with Jessner's peel followed by 20% TCA was done and in Group II patients chemical peeling with 20% TCA peel alone was done. In Group I (Jessner's peel and 20% TCA), mild improvement of acne scars was seen in 8% cases, moderate improvement in 32% cases and marked improvement of acne scars was seen in 60% patients. In Group II (20% TCA), mild improvement of acne scars was seen in 32% cases, moderate improvement in 40% cases and marked improvement of acne scars was seen in 28% patients. But, the difference in improvement of acne scars was not statistically significant in both the groups (P value > 0.05).

    Background Regenerative medicine holds promise for restoring voice in patients with vocal fold scarring. As experimental treatments approach clinical translation, several considerations remain. Our objective was to evaluate efficacy and biocompatibility of four bone marrow mesenchymal stromal cell (BM-MSC) and tunable hyaluronic acid based hydrogel (HyStem-VF) treatments for vocal fold scar using clinically acceptable materials, a preclinical sample size and a dosing comparison. Methods Vocal folds of 84 rabbits were injured and injected with four treatment variations (BM-MSC, HyStem-VF, and BM-MSC in HyStem-VF at two concentrations) 6 weeks later. Efficacy was assessed with rheometry, real-time polymerase chain reaction (PCR) and histology at 2, 4 and 10 weeks following treatment. Lung, liver, kidney, spleen and vocal folds were screened for biocompatibility by a pathologist. Results and discussion Persistent inflammation was identified in all hydrogel-injected groups. The BM-MSC alone treatment appeared to be the most efficacious and safe, providing an early resolution of viscoelasticity, gene expression consistent with desirable extracellular matrix remodeling (less fibronectin, collagen 1α2, collagen 3, procollagen, transforming growth factor [TGF]β1, alpha smooth muscle actin, interleukin-1β, interleukin-17β and tumor necrosis factor [TNF] than injured controls) and minimal inflammation. Human beta actin expression in BM-MSC–treated vocal folds was minimal after 2 weeks, suggesting that paracrine signaling from the BM-MSCs may have facilitated tissue repair. PMID:27637759

    Full Text Available Abstract Background The aim of the study was to perform a feature tracking analysis on cine magnetic resonance (MR images to elucidate if functional measurements of the motion of the left ventricular wall may detect scar defined with gadolinium enhanced MR. Myocardial contraction can be measured in terms of the velocity, displacement and local deformation (strain of a particular myocardial segment. Contraction of the myocardial wall will be reduced in the presence of scar and as a consequence of reduced myocardial blood flow. Methods Thirty patients (3 women and 27 men were selected based on the presence or absence of extensive scar in the anteroseptal area of the left ventricle. The patients were investigated in stable clinical condition, 4-8 weeks post ST-elevation myocardial infarction treated with percutaneous coronary intervention. Seventeen had a scar area >75% in at least one anteroseptal segment (scar and thirteen had scar area Results In the scar patients, segments with scar showed lower functional measurements than remote segments. Radial measurements of velocity, displacement and strain performed better in terms of receiver-operator-characteristic curves (ROC than the corresponding longitudinal measurements. The best area-under-curve was for radial strain, 0.89, where a cut-off value of 38.8% had 80% sensitivity and 86% specificity for the detection of a segment with scar area >50%. As a percentage of the mean, intraobserver variability was 16-14-26% for radial measurements of displacement-velocity-strain and corresponding interobserver variability was 13-12-18%. Conclusion Feature tracking analysis of cine-MR displays velocity, displacement and strain in the radial and longitudinal direction and may be used for the detection of transmural scar. The accuracy and repeatability of the radial functional measurements is satisfactory and global measures agree.

    Accurate diagnosis of myocardial infarction (MI) is of paramount importance in patient management, which necessitates the development of efficient and accurate diagnostic methods. Q wave is not present in all patients with MI, and its prevalence is declining. Recently, fragmented QRS (fQRS) complex has been introduced as a marker of prior MI. To investigate diagnostic value of fQRS compared to Q wave. We included 500 consecutive patients with known or suspected coronary artery disease who underwent two days of gated myocardial perfusion imaging using dipyridamole pharmacologic stress. Electrocardiogram (ECG) was evaluated to detect fQRS as well as Q-wave. Finally, subjects were compared in terms of ventricular perfusion and function indices. A total of 207 men and 269 women with mean age of 57.06 ± 12 years were studied. ECG analysis showed that 14.3% of the patients had both fQRS and Q waves, 30.7% had fQRS, and 3.8% had Q waves. Fixed myocardial perfusion defect was noted in 22.3% of patients according to MPIs. Sensitivity, specificity, and positive and negative predictive values for myocardial scar detection were 78%, 65%, 39%, and 91%, respectively, for fQRS and 61%, 94%, 76%, and 89%, respectively, for Q wave. Although fQRS had lower specificity compared to Q wave in the detection of myocardial scar, due to higher sensitivity and negative predictive value can be an invaluable diagnostic index. There is also an incremental value for fQRS in association with Q-wave in myocardial scar assessment.

    Full text: Sensitive detection of acute peri-osseous scar tissue should be valuable for detection of partial ligamentous, tears and other common rheumatological conditions including back pain and ligamentous scars. Our aim was to investigate acute scar uptake of {sup 99m}Tc(V)-DMSA (dimercapto-succinic-acid), {sup 99m}Tc-DMAD (di- methyl-aminodiphosphonate) compared to {sup 99m}Tc-MDP (methylen-diphosphonate), the standard bone-scanning radiopharmaceutical. New Zealand white rabbits were anaesthetised and had 5-7cm of their mid-line abdominal wall surgically incised. At 24, 48, 72, 96 and 240 hours post surgery, 74 MBq (2 mCi) of the above radiopharmaceuticals were injected intravenously and scintigraphy performed 2.5 hours later. Relative count rate in scar is tabulated. In conclusion, the increased activity in the acute surgical site and lesser bone uptake confirmed that Tc (V)-DMSA and Tc-DMAD are superior to Tc- MDP for detection of new scar tissue in the region of bone. 1 tab.

    Hypertrophic scarring is seen regularly. Tissue penetration of laser energy into hypertrophic scars using computer defaults from some lasers may be insufficient and penetration not enough. We have developed a treatment with an interrupted laser "drilling" by the Ultrapulse CO 2 (Manual Fractional Technology, MFT) and, a second pass, with fractional CO 2 . The MFT with fractional CO 2 lasers to treat hypertrophic scars is evaluated. A total of 158 patients with hypertrophic scars had three sessions of MFT with fractional CO 2 laser at 3-month intervals. Evaluations made before and 6 months after the 3rd treatment: (1) the Vancouver Scar Scale (VSS), (2) the University of North Carolina (UNC) Scar Scale, and (3) a survey of patient satisfaction. All data were analyzed using a t-test before and after treatment. The VSS score decreased from 9.35 to 3.12 (Plaser drilling by MFT and a fractional CO2 laser had profound effects on the hypertrophic scars treated. It works by increasing the penetration depth of the CO 2 laser in the scar tissue, exerting more precise effects on the hypertrophic scars. MFT combined with fractional CO 2 laser has the potential to be a major advance in the treatment of hypertrophic scars. © 2017 Wiley Periodicals, Inc.

    There have been significant advances in the management of complex colorectal polyps. Previous failed resection or polyp recurrence is associated with significant fibrosis, making endoscopic resection extremely challenging; the traditional approach to these lesions is surgery. The aim of this study was to evaluate the efficacy of a novel, knife-assisted snare resection (KAR) technique in the resection of scarred colonic polyps. This was a prospective cohort study of patients, in whom the KAR technique was used to resect scarred colonic polyps > 2  cm in size. Patients had previously undergone endoscopic mucosal resection (EMR) and developed recurrence, or EMR had been attempted but was aborted as a result of technical difficulty. A total of 42 patients underwent KAR of large (median 40  mm) scarred polyps. Surgery for benign disease was avoided in 38 of 41 patients (93 %). No life-threatening complications occurred. Recurrence was seen in six patients (16 %), five of whom underwent further endoscopic resection. The overall cure rate for KAR in complex scarred colonic polyps was 90 %. KAR of scarred colonic polyps by an expert endoscopist was an effective and safe technique with low recurrence rates. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background: Alopecia is one of the most important hair follicle (HF disorders, which is divided into scarring (cicatricial and nonscarring (noncicatricial types. Objective: The aim of this study is to investigate the expression of stem cell (SC markers such as cytokeratin (CK 17 and CK19 in scarring and nonscarring alopecia. Materials and Methods: Thirty patients with scalp alopecia (15 with scarring alopecia and 15 without together with ten healthy volunteers were included in this study. Biopsies were taken from all participants and stained for CK17 and CK19 using immunohistochemistry. Results: There was a statistically significant difference between the nonscarring group and the control group with regard to CK17 expression in the outer layers of the HFs (P = 0.00 and CK19 staining of the inner layers of the HFs (P = 0.008. There was a statistically significant difference between the scarring and the control groups regarding CK17 expression in the outer (P = 0.00 and the inner layers (P = 0.00 of the HFs and CK19 expression in the inner layers of the HFs (P = 0.00. CK17 expression in the outer layers (P = 0.02 and the inner layers of the HFs (P = 0.00 together with CK19 expression in the inner layers of the HFs (P = 0.00 showed statistically significant differences between scarring and nonscarring alopecia groups. Conclusions: The presence of SC markers (CK17 and CK19 in the HFs was affected in both scarring and nonscarring alopecia, but the defect in scarring alopecia is more evident than that of nonscarring alopecia. The persistence of SC markers in some types of scarring alopecia could give a hope for the recovery of these lesions. Further studies are recommended to clarify the benefit from using HF SCs in the treatment of alopecia.

There was a statistically significant difference between the scarring and the control groups regarding CK17 expression in the outer (P = 0.00) and the inner layers (P = 0.00) of the HFs and CK19 expression in the inner layers of the HFs (P = 0.00). CK17 expression in the outer layers (P = 0.02) and the inner layers of the HFs (P = 0.00) together with CK19 expression in the inner layers of the HFs (P = 0.00) showed statistically significant differences between scarring and nonscarring alopecia groups. Conclusions: The presence of SC markers (CK17 and CK19) in the HFs was affected in both scarring and nonscarring alopecia, but the defect in scarring alopecia is more evident than that of nonscarring alopecia. The persistence of SC markers in some types of scarring alopecia could give a hope for the recovery of these lesions. Further studies are recommended to clarify the benefit from using HF SCs in the treatment of alopecia. PMID:27761086

    BACKGROUND: The Bacillus Calmette-Guérin vaccine (BCG) against tuberculosis is administered intradermally, and vaccination is often followed by a scar at the injection site. Among BCG-vaccinated individuals, having a scar has been associated with lower mortality. We aimed to examine the impact...... of vaccination technique for scarring in a high income setting, by assessing the associations between the post injection reaction, the wheal size, and the probability of developing a scar, and scar size. METHODS: This study was nested within a clinical multicenter study randomizing 4262 infants to either BCG...... vaccination (BCG 1331 SSI) or no intervention. In this substudy, including 492 vaccinated infants, the immediate post BCG vaccination reaction was registered as either wheal (a raised, blanched papule at the injection site), bulge (a palpable element at the injection site), or no reaction. The presence...

    Full Text Available Abstract Introduction Keloid scars following median sternotomy are rare and occur more frequently in pigmented skin. Different management strategies have been described with variable success. We present a case of keloid scar formation following cardiac surgery including our management and the final aesthetic result. Case description A 64 year old female of fair complexion underwent mitral valve replacement. The procedure and postoperative recovery were uncomplicated, however, during the following year, thick keloid scars formed over the incision sites. Initial non surgical measures failed to relieve pain and did not offer any tangible aesthetic benefit. Eventually surgical excision was attempted. She presented to our clinic for nine months follow up with significant improvement in pain and aesthetic result. Discussion and Evaluation Several theories have attempted to explore the pathophysiology of keloid scar formation. A number of predisposing factors have been documented however none existed in this case. A variety of invasive and non invasive approaches have been described but significant differences in success rates and methodology of investigations still precludes a standardized management protocol. Conclusions In this case study a rare presentation of keloid scar has been presented. The variety of methods used to improve pain and aesthetic result demonstrates the propensity of keloid scars to recur and the therapeutic challenges that surgeons have to face in their quest for a satisfactory patient outcome.

    Myocardial infarction is the major cause of cardiac injury in western countries and can result in a massive loss of heart cells, leading eventually to heart failure. A fibrotic collagen-rich scar may prevent ventricular wall rupture, but also may result in heart failure because of its stiffness. In zebrafish, cardiac cryoinjury triggers a fibrotic response and scarring. Unlike with mammals, zebrafish heart has the striking ability to regenerate and to resolve the scar. Thus, understanding the mechanisms of scar resolution in zebrafish heart might facilitate the design of new therapeutic approaches to improve the recovery of patients. To visualize the collagenolytic activity within the zebrafish heart following cryoinjury, we used an in situ collagen zymography assay. We detected expression of mmp2 and mmp14a and these matrix metalloproteinases might contribute to the collagenase activity. Collagenolytic activity was present in the wound area, but decreased as the myocardium regenerated. Comparison with neonatal mouse hearts that failed to regenerate after transmural cryoinjury revealed a similar collagenolytic activity in the scar. These findings suggest that collagenolytic activity may be key to how the zebrafish heart resolves its scar; however, it is not sufficient in mouse hearts that lack efficient myocardial regeneration.

    2012-01-01

    Full Text Available Chemical peeling is a widely used procedure in the management of acne and acne scars, but there are very few studies on Asian populations who are more prone to develop hyper pigmentation. This article aims to summarize and evaluate the existing studies on the role of chemical peels in the treatment of acne and acne scars among Asians. An online search was conducted to identify prospective studies published in English that evaluated the use of chemical peels in active acne and acne scars in Asian populations. There were six studies for acne and eight studies for acne scars that were identified using our search parameters. Most were single-centre, open label and with small sample sizes. Acne severity was not uniformly reported and the objective outcome measures of some studies were not explicitly reported as well. The general trend of the results of the studies support the safety and efficacy of chemical peels for acne and acne scars including those of darker skin types. The existing studies support the use of chemical peels in the treatment of acne and acne scars in Asians. Further clinical trials with better study design and more subjects are needed to further establish the role of chemical peels in Asian acne patients.

    Background. Gadolinium-enhanced MRI has recently been employed in the diagnosis of acute pyelonephritis. Its potential utility in the diagnosis of renal scars in children is unknown. Objective. To evaluate the potential utility of MRI using fat-saturated T1-weighted (T1-W) and post-gadolinium, short-tau inversion-recovery (STIR) sequences in detecting renal scarring by comparison with technetium dimercaptosuccinic acid ( 99 m Tc-DMSA) renal scintigraphy in children at risk of renal scarring. Materials and methods. A group of 24 children with spina bifida and neurogenic bladder or anorectal anomaly was studied. No patient had a history of acute pyelonephritis. Documented urinary tract infection (UTI) was present in 10 children (42 %). The remaining 14 (58 %) children had a history of asymptomatic bacteriuria. None had clinical signs or symptoms of acute UTI at the time of the study. 99 m Tc-DMSA and MRI were performed to detect renal scarring. 99 m Tc-DMSA scans were supplemented with pinhole imaging. MRI of the kidneys employed a fat-saturated T1-W sequence and a post-gadolinium STIR sequence employing a short echo time. Results. Of the kidneys studied, 33 % (n = 16) had evidence of a renal parenchymal defect suggestive of scarring on 99 m Tc-DMSA. The concordance in the detection of a scarred kidney by post-gadolinium STIR sequence and 99 m Tc-DMSA is 94 %; that by fat-saturated T1-W sequence and 99 m Tc-DMSA is 82 %; that by both sequences (positive result on either sequence) and 99 m Tc-DMSA is 100 %. Using 99 m Tc-DMSA as the gold standard, MRI had a sensitivity of 100 % and a specificity of 78 % in the diagnosis of a scarred kidney. The concordance in the detection of a scarred zone by post-gadolinium STIR sequence and 99 m Tc-DMSA is 68 %; that by fat-saturated T1-W sequence and DMSA is 44 %; that by both sequences (positive result on either sequence) and 99 m Tc-DMSA is 84 %. MRI had a sensitivity of 84 % and a specificity of 86 % in the diagnosis of a

    Objective: To evaluate uterine arterial chemoembolization combined with curettage in treating cesarean scar pregnancy. Methods: Super-selective bilateral uterine arterial catheterization and angiography was performed in 64 patients with cesarean scar pregnancy (duration of amenorrhea 43-84 days), which was followed by arterial infusion of MTX and embolization with Gelfoam particles. Then curettage was carried out. The technical success rate and the therapeutic results were observed and analyzed. Results: Technical success in catheterization and in performing chemoembolization was achieved in all 64 patients. The pregnant tissues were successfully cleared away in 62 patients. The average blood loss during curettage procedure was 21.4 ml. For the remaining two patients lesion resection together with repair of lower segment was employed. No severe complications occurred after the treatment. Conclusion: Uterine arterial chemoembolization combined with curettage is a safe,minimally-invasive and effective treatment for cesarean scar pregnancy. It is worth popularizing this technique in clinical practice. (authors)

    One of the unique roles of forensic nurses is to conduct risk assessments. Establishing a therapeutic nurse-patient relationship helps forensic nurses perform accurate and useful risk assessments. Accurate risk assessments can facilitate formulation of individualized risk management plans, designed to meet patients' needs and ensure public safety. The importance of forensic nurses' knowledge and application of appropriate communication and proper documentation cannot be overemphasized.

    Full Text Available This study was undertaken to determine the predisposing factors for renal scarring in children with urinary tract infection. In this prospective cohort study, 176 children with documented urinary tract infection were categorized into four groups: ≤1 year old, 1-2 years old, 2-7 years and 7-14 years old. Ultrasonography and Technetium-99 m-DMSA scan were used to detect the possible abnormalities. Infants under 12 months old presented as the most common group for renal scarring (27 cases, 52.9%, and vesicoureteral reflux (VUR was diagnosed in 29 cases (56.8%. Fifteen (41.67% children between the ages of one and two years had renal scar, and VUR was detected in half of the patients. In the third group, 36.3%, and in fourth group, 41.6% of the patients had renal scar. Also, 38.6% in group three and 50% in the final group had VUR. A co-incidental finding that was observed in this study was the high incidence of pseudohypoaldesteronism (PHA in our patients: in 39.2% of the children in group one, 22.2% in group two and 4% in group three. In group four however, none of the patients had PHA. Risk of scar formation with urinary tract infection (UTI was higher in the younger age group and in those with recurrent UTIs.

    Beta radiation of 90 Sr can inhibit the scarring formation so that the success rate of filtration surgery may be improved. After success in animal experiment, trabeculectomy was performed with small sclera flap on 31 eyes of 23 cases of patients with a high risk of scarring formation. Local 90 Sr radiation with a total dosage of 30.24 Gy were given by several times 3 days postoperatively, combined with local use of steroids. The patients were followed-up at 1 to 24 months, averaging 7 months. The intraocular pressure were successfully controlled in 90.3% of the patients. No lens impairment and other complications were observed. This procedure is an adoptive method in preventing scarring formation after glaucoma filtering surgery

    Facial linear scleroderma results in depressed atrophic scars. Autologous fat transplantation has been widely used, and fat appears to be an ideal material for filling depressed atrophic scars and contour deformities, but long-term results for autologous fat transplantation are controversial. To review the short- and long-term results of 20 patients who underwent multiple autologous fat transplantations for depressed atrophic scar correction. Twenty patients with clinically inactive facial linear scleroderma were included. They received at least two transplantations and had a 12-month follow-up evaluation. On the forehead, 51% to 75% improvement (average grading scale: 2.4) was achieved when observed at least 12 months after the last treatment. For the chin, correction was poor (average grading scale: 0.7) with less than 25% improvement. The infraorbital area showed fair correction, but the nose showed poor correction. Two of three patients with scalp reduction surgery showed excellent results, showing only slight scar widening. Autologous fat transplantation is an effective method for long-term correction of depressed atrophic scars left by linear scleroderma on the forehead but is less effective for corrections on the nose, infraorbital area, and chin.

  11. The Role of Vitamin D in Non-Scarring Alopecia

    Full Text Available Non-scarring hair loss is a common problem that affects both male and female patients. Since any disturbances in the hair follicle cycle may lead to hair shedding, or alopecia, it is not surprising that the possible role of vitamin D in alopecia was investigated in many studies. Vitamin D has been shown to have many important functions. A growing body of evidence shows that vitamin D and its receptor are responsible for maintaining not only calcium homeostasis but also skin homeostasis. Moreover, vitamin D could also regulate cutaneous innate and adaptive immunity. This paper presents a review of current literature considering the role of vitamin D in alopecia areata, telogen effluvium, and female pattern hair loss. The majority of studies revealed decreased serum 25-hydroxyvitamin D levels in patients with different types of non-scarring alopecia, which could suggest its potential role in the pathogenesis of hair loss. According to the authors, vitamin D supplementation could be a therapeutic option for patients with alopecia areata, female pattern hair loss, or telogen effluvium. However, further studies on a larger group of patients are required.

    Chaotic systems are unstable and extremely sensitive to initial condititions. So far, scientists have been unable to demonstrate that the same kind of behaviour exists in quantum or microscopic systems. New connections have been discovered though between classical and quantum theory. One is the phenomena of 'scars' which cut through the wave function of a particle (1 page).

    2015-01-01

    The recent proliferation of oil and natural gas energy development in the Greater Green River Basin of southwest Wyoming has accentuated the need to understand wildlife responses to this development. The location and extent of surface disturbance that is created by oil and natural gas well pad scars are key pieces of information used to assess the effects of energy infrastructure on wildlife populations and habitat. A digital database of oil and natural gas pad scars had previously been generated from 1-meter (m) National Agriculture Imagery Program imagery (NAIP) acquired in 2009 for a 7.7-million hectare (ha) (19,026,700 acres) region of southwest Wyoming. Scars included the pad area where wellheads, pumps, and storage facilities reside and the surrounding area that was scraped and denuded of vegetation during the establishment of the pad. Scars containing tanks, compressors, the storage of oil and gas related equipment, and produced-water ponds were also collected on occasion. This report updates the digital database for the five counties of southwest Wyoming (Carbon, Lincoln, Sublette, Sweetwater, Uinta) within the Wyoming Landscape Conservation Initiative (WLCI) study area and for a limited portion of Fremont, Natrona, and Albany Counties using 2012 1-m NAIP imagery and 2012 oil and natural gas well permit information. This report adds pad scars created since 2009, and updates attributes of all pad scars using the 2012 well permit information. These attributes include the origination year of the pad scar, the number of active and inactive wells on or near each pad scar in 2012, and the overall status of the pad scar (active or inactive). The new 2012 database contains 17,404 pad scars of which 15,532 are attributed as oil and natural gas well pads. Digital data are stored as shapefiles projected to the Universal Transverse Mercator (zones 12 and 13) coordinate system. These data are available from the U.S. Geological Survey (USGS) at http://dx.doi.org/10

    The management of keloids and hypertrophic scars continues to challenge health-care providers. Though both forms of pathologic scarring are distinct entities at the macro and microscopic level, their etiologies and treatment are often similar. Potential treatment approaches are progressing, and combinations of treatment options have been proposed in the literature with promising outcomes. The treatment evolution has reached a level where molecular therapeutic modalities are being investigated. Currently, no gold standard treatment exists. Overall success rates and patient satisfaction seem to be slowly climbing, but additional investigational studies must continue to be performed. Several studies have investigated antineoplastic agents, and there seems to be a marked improvement in rates of recurrence, patient satisfaction, and overall quality of scar when these agents are used. Intralesional injection and/or wound irrigation with interferon-a2b, interferon-g, mitomycin-C, bleomycin, or 5-fluorouracil seems to have a positive effect on the reduction of pathologic scars. There is mounting evidence that these drugs used alone or in combination therapy, have the potential to be an integral part of the treatment paradigm for hypertrophic scars and keloids.

    Keloid and hypertrophic scars are abnormal manifestations of wounds that occur following skin injuries in the form of local proliferation of fibroblasts and increased production of collagen. There are several ways to cure these scars; treatment must be selected based on the nature of the scars. In this clinical trial, two methods-cryotherapy and intense pulsed light (IPL)-are compared in the treatment of scars, and the results are presented in terms of improvement level, complications, and patient satisfaction. This clinical trial was conducted in southeastern Iran. The intervention group included scars that underwent the IPL method and the control group, which consisted of scars that were subjected to cryotherapy. In both methods, intralesional corticosteroid injection was administered. To select samples, the easy sampling method was used. To determine the expected outcomes, the criteria determined in the Vancouver scar scale were used. Data were analyzed using the Mix Model, chi-square test, and t test. In this study, 166 samples of keloid and hypertrophic scars were cured using two methods (Cryotherapy, 83; IPL, 83). The recovery rate was higher in the Cryotherapy group than in the IPL group ( p  > 0.05), and the incidence of complications was also higher in the Cryotherapy group (14.5% vs. 12%). Moreover, patients were more satisfied, although not significantly so, with the cryotherapy method ( p  = 0.09). Both methods were highly successful in curing scars; participants were totally satisfied with both methods.

    Acne vulgaris affects about 85% of adolescents, often extending into adulthood. Psychosocial impact of acne on health-related quality of life (QoL) has been identified, but it remains under-evaluated, especially in Indian patients. This study was aimed to assess the impact of acne and its sequelae on the QoL. This was a hospital-based, prospective, cross-sectional study done between June and November 2014 on 114 consenting patients above 15 years of age with acne vulgaris. Acne vulgaris and its sequelae were graded, and QoL was assessed by using Dermatology Life Quality Index (DLQI) questionnaire. Most cases (64%) were between 15 and 20 years. Females (57%) outnumbered males. Facial lesions (61.4%) and grade II acne were most common. Mean DLQI score was 7.22. DLQI scores were statistically influenced by the age of the patient, duration and grade of acne, acne scar, and postacne hyperpigmentation. This study showed significant impairment of QoL in acne patients. Assurance and counseling along with early treatment of acne vulgaris are important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment.

     We undertook a randomized clinical trial to examine the outcome of a single vs. a double layer uterine closure using ultrasound to assess uterine scar thickness.  Participating women were allocated to one of three uterotomy suture techniques: continuous single layer unlocked suturing, continuous locked single layer suturing, or double layer suturing. Transvaginal ultrasound of uterine scar thickness was performed 6 weeks and 6 - 24 months after Cesarean delivery. Sonographers were blinded to the closure technique.  An "intent-to-treat" and "as treated" ANOVA analysis included 435 patients (n = 149 single layer unlocked suturing, n = 157 single layer locked suturing, and n = 129 double layer suturing). 6 weeks postpartum, the median scar thickness did not differ among the three groups: 10.0 (8.5 - 12.3 mm) single layer unlocked vs. 10.1 (8.2 - 12.7 mm) single layer locked vs. 10.8 (8.1 - 12.8 mm) double layer; (p = 0.84). At the time of the second follow-up, the uterine scar was not significantly (p = 0.06) thicker if the uterus had been closed with a double layer closure 7.3 (5.7 - 9.1 mm), compared to single layer unlocked 6.4 (5.0 - 8.8 mm) or locked suturing techniques 6.8 (5.2 - 8.7 mm). Women who underwent primary or elective Cesarean delivery showed a significantly (p = 0.03, p = 0.02, "as treated") increased median scar thickness after double layer closure vs. single layer unlocked suture.  A double layer closure of the hysterotomy is associated with a thicker myometrium scar only in primary or elective Cesarean delivery patients. © Georg Thieme Verlag KG Stuttgart · New York.

    Acne scars are a major concerning problem to all acne patients affecting their quality of life. Platelet-rich plasma (PRP) and fractional CO 2 laser are innovative treatment modalities for acne scars. Carboxytherapy can also be used to improve scar tissue through the increase in collagen deposition and reorganization, and the improvement in skin texture and tone. The aim of this work was to compare the efficacy, safety, and complications of the intradermal injection of PRP combined with carboxytherapy and PRP combined with fractional CO 2 laser, in the treatment of atrophic acne scars. Forty patients with atrophic acne scars were divided into 2 groups. Group A included 20 patients and was subjected to three fractional CO 2 laser sessions combined with PRP injection. Group B included 20 patients and was subjected to three sessions of carboxytherapy combined with PRP injection. Both fractional CO 2 laser and carboxytherapy combined with PRP showed improvement in acne scars and patients' satisfaction but the improvement with fractional CO 2 laser was significantly better than carboxytherapy but with more side effects. Improvement of acne scars was noted in both treatment modalities with obvious higher and statistically significant results in favor of fractional CO 2 laser but with more side effects. Carboxytherapy is a promising tool in treatment of acne scars with less complication. © 2018 Wiley Periodicals, Inc.

    Fire scars are used widely to reconstruct historical fire regime parameters in forests around the world. Because fire scars provide incomplete records of past fire occurrence at discrete points in space, inferences must be made to reconstruct fire frequency and extent across landscapes using spatial networks of fire-scar samples. Assessing the relative accuracy of fire-scar fire history reconstructions has been hampered due to a lack of empirical comparisons with independent fire history data sources. We carried out such a comparison in a 2780-ha ponderosa pine forest on Mica Mountain in southern Arizona (USA) for the time period 1937-2000. Using documentary records of fire perimeter maps and ignition locations, we compared reconstructions of key spatial and temporal fire regime parameters developed from documentary fire maps and independently collected fire-scar data (n = 60 plots). We found that fire-scar data provided spatially representative and complete inventories of all major fire years (> 100 ha) in the study area but failed to detect most small fires. There was a strong linear relationship between the percentage of samples recording fire scars in a given year (i.e., fire-scar synchrony) and total area burned for that year (y = 0.0003x + 0.0087, r2 = 0.96). There was also strong spatial coherence between cumulative fire frequency maps interpolated from fire-scar data and ground-mapped fire perimeters. Widely reported fire frequency summary statistics varied little between fire history data sets: fire-scar natural fire rotations (NFR) differed by or = 25% of study area burned) were identical between data sets (25.5 yr); fire-scar MFIs for all fire years differed by 1.2 yr from documentary records. The known seasonal timing of past fires based on documentary records was furthermore reconstructed accurately by observing intra-annual ring position of fire scars and using knowledge of tree-ring growth phenology in the Southwest.

    We compared the ability of excretory urography (without tomography) and 99mtechnetium-dimercapto-succinic acid renal scanning to detect renal scars in 32 children with primary vesicoureteral reflux. These children did not have hydronephrosis, renal failure or urinary tract obstruction. In all cases both studies were conducted within a 10-month period. The findings from both modalities were in agreement for 51 of the 64 renal units evaluated (80%). Evaluation of the excretory urogram indicated 6 cases of diffuse and 2 of focal scarring that were not detected by evaluation of the renal scan. The sensitivity of excretory urography to detect renal scars was 84% and the specificity was 83%. The 99mtechnetium-dimercapto-succinic acid renal scan showed 5 cases of focal renal scarring not detected by excretory urography. The sensitivity of the renal scan to detect renal scars was 77% and the specificity was 75%. We conclude that neither study alone could effectively replace the other for the detection of renal scars, and recommend that both be included in the initial evaluation and followup of patients with renal scars

    Various methods for correction of accessory axillary breast tissue have been proposed, including simple excision, diamond-shaped excision, a Y-V technique, and lipoplasty. We present an effective method for correction of a prominent axillary mound that combines lipoplasty with excision of accessory breast tissue along the axillary transverse line. Preoperative markings included an incision within the natural wrinkle line in the axillary fold, and demarcation of areas in which lipoplasty and excision were to be performed. After lipoplasty, deep dissection was performed to isolate and remove accessory breast tissue and excess fat tissue. A compression dressing was applied for 1 to 2 weeks postoperatively, and the patient was instructed to wear a sports bra for 1 to 2 months after removal of the dressing. We treated 7 patients using this procedure between October 1999 and March 2003. No major postoperative complications were detected and recurrence was not noted during the follow-up periods. Aesthetic results were satisfactory. We believe that a procedure that combines lipoplasty and excision provides numerous advantages as a surgical option in treating a prominent axillary mound. The main advantage is that the final scar is laid in the natural axillary fold, rendering scars less conspicuous and eliminating the need to remove excess skin. The one disadvantage was that elevation of the skin flap via small, remote incisions initially produced surgical difficulties, but these were overcome with experience.

    Full Text Available Background. The aim of the study was to assess the histological effects of autologous infusion of adipose-derived stem cells (ADSC on a chronic vocal fold scar in a rabbit model as compared to an untreated scar as well as in injection of hyaluronic acid. Study Design. Animal experiment. Method. We used 74 New Zealand rabbits. Sixteen of them were used as control/normal group. We created a bilateral vocal fold wound in the remaining 58 rabbits. After 18 months we separated our population into three groups. The first group served as control/scarred group. The second one was injected with hyaluronic acid in the vocal folds, and the third received an autologous adipose-derived stem cell infusion in the scarred vocal folds (ADSC group. We measured the variation of thickness of the lamina propria of the vocal folds and analyzed histopathologic changes in each group after three months. Results. The thickness of the lamina propria was significantly reduced in the group that received the ADSC injection, as compared to the normal/scarred group. The collagen deposition, the hyaluronic acid, the elastin levels, and the organization of elastic fibers tend to return to normal after the injection of ADSC. Conclusions. Autologous injection of adipose-derived stem cells on a vocal fold chronic scar enhanced the healing of the vocal folds and the reduction of the scar tissue, even when compared to other treatments.

    Hypertrophic scars are a consequence of wound healing. The objective of the present study is to evaluate vitamin D and inflammatory biomarker plasma levels during wound healing. A prospective study was performed in patients (n = 63) submitted to body contouring surgery. Blood samples were collected before (t 0 ) and 5 days after surgery (t 5 ). Blood cell count, protein inflammatory biomarkers, and circulating plasma levels of 25(OH)D, vitamin A and vitamin E were quantified. Six months after surgery, scars were evaluated and classified as normal or hypertrophic. At the end of the study, 73% of the patients developed a normal scar (control group, n = 46) and 27% of the patients presented hypertrophic scars (HT group, n = 17). The patients in the HT group presented higher eosinophil (0.145 × 10 9 /L vs. 0.104 × 10 9 /L, p = 0.028) and basophil count (0.031 × 10 9 /L vs. 0.22 × 10 9 /L, p = 0.049) and C-reactive protein levels (6.12 mg/L vs. 2.30 mg/L, p = 0.015) in t 0 than the patients in the control group. At t 5 , the patients in the HT group showed a decrease in neutrophil (3.144 × 10 9/L vs. 4.03 × 10 9 /L, p = 0.031) and an increase in basophil (0.024 × 10 9 /L vs. 0.015 × 10 9 /L, p = 0.005) and lymphocyte count (1.836 × 10 9 /L vs. 1.557 × 10 9 /L; p = 0.028). Before surgery, vitamin D plasma levels were found to be decreased by almost 50% (23.52 ng/mL vs. 15.46 ng/mL, p = 0.031) in the patients who developed hypertrophic scars. Thirty-one percent of the patients submitted to bariatric surgery had more hypertrophic scars, versus 24% of the patients with no previous bariatric surgery. There is a different systemic inflammatory profile response in the patients during the formation of hypertrophic scars. Vitamin D plasma levels are marked reduced in these patients. Considering the powerful anti-inflammatory effect of vitamin D, these findings could be related.

    Results of various studies suggest that the hypertrophic and keloid scars are highly prevalent in the general population and are irritating both physically and mentally. Considering the variety of existing therapies, intense pulsed light (IPL) method along with corticosteroid injection was evaluated in treating these scars. 86 subjects were included in this clinical trial. Eight sessions of therapeutic intervention were done with IPL along with corticosteroid intralesional injection using 450 to 1200 NM filter, Fluence 30-40 J/cm2, pulse duration of 2.1-10 ms and palsed delay 10-40 ms with an interval of three weeks. To specify the recovery consequences and complication rate and to determine features of the lesion, the criteria specified in the study of Eroll and Vancouver scar scale were used. The level of clinical improvement, color improvement and scar height was 89.1%, 88.8% and 89.1% respectively. The incidence of complications (1 telangiectasia case, 7 hyperpigmentation cases and 2 atrophy cases) following treatment with IPL was 11.6%. Moreover, the participants' satisfaction with IPL method was 88.8%. This study revealed that a combined therapy (intralesional corticosteroid injection + IPL) increases the recovery level of hypertrophic and keloid scars. It was also demonstrated that this method had no significant side effect and patients were highly satisfied with this method.

    Umbilical scarring is the presence of excess scar tissue deposited between abdominal dermal layers at the site of yolk sac absorption in hatchling American alligators (Alligator mississippiensis). The presence of this dermal condition plays a key evaluatory role in the overall quality and subsequent value for various commercial leather products. Despite the prevalent nature of this condition, currently the industry has no standardized protocols for its quantification. The objectives of this study were to examine the relationship between hatchling weight and age and incidence of umbilical scarring and to develop a quantifiable and reproducible technique to measure this dermal condition in hatchling American alligators. Thirty eggs from each of nine clutches were incubated in two separate incubators at different facilities and hatchling umbilical scarring was measured at 2 and 10 days of age using digital calipers. Umbilical area was calculated by multiplying umbilical length times umbilical width. There was a significant effect of both age and clutch on umbilical area (overall decline of 64%) by 10 days post-hatch. However, only five of the nine clutches utilized expressed a noticeable decline in the size of this dermal condition (range 67-74%). We had hypothesized that larger hatchlings would have larger umbilical areas and a slower rate of improvement in this condition during the first few days post-hatch. The differences in umbilical area and percent decline with age across clutches, however, were not associated with differences in initial hatchling weights. Within clutches and time periods, hatchling weight had no significant effect on the size and/or rate of decline of this condition. ?? 2004 Published by Elsevier B.V.

    Full Text Available CONTEXT: Malnutrition in cirrhotic patients with end-stage disease is common, and the degree of nutritional debilitation can play an important role in the pathogenesis of complications and cause a negative impact on prognosis. However, it involves difficulties and controversies regarding the identification of the best nutritional assessment method. OBJECTIVE: To identify a method that provides a safe and effective nutritional diagnosis. METHODS: Cross-sectional study with 129 cirrhotic patients. Anthropometric measurements, subjective global assessment, hand grip strength and bioelectrical impedance. RESULTS: Through phase angle of bioelectrical impedance analysis (BIA method, significant associations with Child-Pugh (P = 0.008, age group and gender were observed. The ROC (receiver operator characteristic curve was generated to determine the best cutoff point of the phase angle of cirrhotic patients, serving as one of the reference parameters for the nutritional assessment with bioimpedance in this study, considering the classification through Child-Pugh score as the reference standard for the clinical conditions of patients with cirrhosis. CONCLUSIONS: The assessment through bioelectrical impedance presented a statistically significant correlation with Child-Pugh score. The identification of phase angle of 5.44º is the new parameter suggested for the classification of the nutritional conditions of cirrhotic patients.

    Keloids and hypertrophic scars are the most common types of pathological scarring. Traditionally, keloids have been considered as a result of aberrant wound healing, involving excessive fibroblast participation that is characterized by hyalinized collagen bundles. However, the usefulness of this characterization has been questioned. In recent years, studies have reported the appropriate use of verapamil for keloids and hypertrophic scars. Searches were conducted on the databases Medline, Embase, Cochrane, PubMed, and China National Knowledge Infrastructure from 2006 to July 2016. State12.0 was used for literature review, data extraction, and meta-analysis. Treatment groups were divided into verapamil and nonverapamil group. Nonverapamil group includes steroids and intense pulsed light (IPL) therapy. Total effective rates include cure rate and effective rate. Cure: skin lesions were completely flattened, became soft and symptoms disappeared. Efficacy: skin lesions subsided, patient significantly reduced symptoms. Inefficient definition of skin was progression free or became worse. Random-effects model was used for the meta-analysis. Six studies that included 331 patients with keloids and hypertrophic scars were analyzed. Analysis of the total effective rate of skin healing was performed. The total effective rates in the two groups were 54.07% (verapamil) and 53.18% (nonverapamil), respectively. The meta-analysis showed that there was no difference between the two groups. We also compared the adverse reactions between the verapamil treatment group and the steroids treatment group in two studies, and the result indicated that the verapamil group showed less adverse reactions. There were no differences between the application of verapamil and nonverapamil group in keloids and hypertrophic scars treatment. Verapamil could act as an effective alternative modality in the prevention and treatment of keloid and hypertrophic scars. A larger number of studies are required to

    Full Text Available Objectives: To describe pharmacists’ opinions regarding which patient assessment skills are necessary to understand and/or perform to provide optimal patient care in pharmacy practice. Methods: An online questionnaire was distributed to pharmacists licensed in North Carolina (n=14,167, as identified by the Board of Pharmacy. The 80 patient assessment items in the questionnaire were derived from a course text book and faculty experience. Participants indicated whether they “need to understand and be able to perform”, “need to understand only”, or “not need to understand or be able to perform” each item in their current practice setting. Descriptive statistics were used to describe background demographics and perceived need for each item. Post-hoc chi-square analyses were performed to determine differences in need based on practice setting and Pharm.D. degree completion. Results: Of 1036 responses received, 770 were used in data analysis; incomplete questionnaires and non-practicing pharmacist responses were excluded. Fifty-nine percent of respondents held a Pharm.D. degree. Participants identified their practice site(s as inpatient (29%, outpatient (16%, community/retail (50%, long term care (5%, and other (8%. The top five patient assessment items respondents identified as important to understand and perform included automatic blood pressure measurement (63%, point of care testing (57%, manual blood pressure measurement (53%, heart rate measurement (52%, and peak flow meter use (47%. Post-hoc analyses showed a significant difference among those with a Pharm.D. versus those without for the response “need to understand and be able to perform” for 20 patient assessment items; a significant difference was also noted among practice settings for 29 items. Conclusions: The top items pharmacists identified they need to both understand and perform could be applied in various practice settings. The study results may guide which patient

    Long-term function following severe burns to the hand may be poor secondary to scar adhesions to the underlying tendons, webspaces, and joints. In this pilot study, we report the feasibility of applying a pasty dermal matrix combined with percutaneous cannula teno- and adhesiolysis. In this 6 month follow-up pilot study, we included eight hands in five patients with hand burns undergoing minimal-invasive, percutaneous cannula adhesiolysis and injection of INTEGRA™ Flowable Wound Matrix for a pilot study of this new concept. The flowable collagen-glycosaminoglycan wound matrix (FCGWM) was applied with a buttoned 2mm cannula to induce formation of a neo-gliding plane. Post treatment follow-up was performed to assess active range of motion (AROM), grip strength, Disabilities of the Arm, Shoulder and Hand (DASH) score, Vancouver Scar Scale (VSS) and quality of life Short-Form (SF)-36 questionnaire. No complications were detected associated with the treatment of FCGWM injection. The mean improvement (AROM) at 6 months was 30.6° for digits 2-5. The improvement in the DASH score was a mean of 9 points out of 100. The VSS improved by a mean of 2 points out of 14. The study demonstrates the feasibility and safety of percutaneous FCGWM for dermal augmentation after burn. Results from this pilot study show improvements in AROM for digits 2-5, functional scores from the patient's perspective (DASH) and scar quality (VSS). The flowable form of established INTEGRA™ wound matrix offers the advantage of minimal-invasive injection after scar release in the post-burned hand with a reduction in the risk of postsurgical re-scarring.

    Silicone gel sheeting has been introduced to prevent scarring, but objective evidence for its usefulness in scar healing is limited. Therefore, the authors' objective was to examine the effectiveness of silicone gel sheeting by randomly applying it to only unilateral scars from a bilateral hallux valgus surgery with symmetrical closure. In a prospective randomized, blinded, intraindividual comparison study, the silicone gel sheeting was applied to 1 foot of a hallux valgus incision scar (an experiment group) for 12 weeks upon removal of the stitches, whereas the symmetrical scar from the other foot was left untreated (a control group). The scars were evaluated at 4 and 12 weeks after the silicon sheet application. The Vancouver Scar Scale was used to measure the vascularity, pigmentation, pliability, height, and length of the scars. Adverse effects were also evaluated, and they included pain, itchiness, rash, erythema, and skin softening. At weeks 4 and 12, the experiment group scored significantly better on the Vancouver Scar Scale in all items, except length (P sheet does not cause adverse effects (P sheet application did show a significant improvement in prevention of postoperative scarring.

    The differential diagnosis between calcified pleural scars and pleural empyemas with mural calcification was studied by computer tomography, bearing in mind the patient's history. In view of the high complication rate of pleural empyemas, such as internal or external fistulae, it is desirable to elucidate every form of pleural shadowing which is more than 20 mm thick. Criteria are offered, which permit the differentiation of the pleural changes by means of conventional radiological examinations. Valuable additional information can be obtained by computer tomography. Forty-nine patients with calcification in the pleura were found among 1.900 chest x-rays which had been examined. Out of these, seven had a pleural empyema. In one case an echinococcus cyst with mural calcification was punctured under X-ray control.

    Body image is associated with self-esteem and identity and has a close relationship with quality of life (QoL). We compared the impact of surgical scars on the patient's perception of body image between conventional open thyroidectomy (OT) and robotic thyroidectomy (RT) in female papillary thyroid carcinoma patients. From October 2009 to December 2010, we enrolled prospectively 116 papillary thyroid carcinoma patients who underwent total thyroidectomy at the Yonsei University Health System (Seoul, Korea). Of these 116 patients, 56 had OT and 60 RT. Their scars were assessed using the Vancouver Scar Scale (VSS), and psychometric properties were evaluated using the Body Image Scale (BIS) questionnaire postoperatively. Both groups were compared using cross-sectional and time-series methods. Mean age was significantly younger in the RT group. Regarding scar quality, the OT group showed superiority in scar pigmentation and the total VSS score during the early postoperative period, but the VSS score improved over time and was similar between both groups at 9 months. The RT group had better scores regarding most of the BIS items, a trend that remained relatively constant over time. In patients with noticeable scars (VSS ≥ 2) at 9 months, the RT group had better BIS scores regarding almost all items, including "self-conscious," "physical attractiveness," "feeling of less feminine," "sexual attractiveness," "dissatisfaction with body, scar and appearance when dressed," and "avoidance of people due to appearance." RT provides a better self-body image and improves QoL compared with conventional OT by avoiding a noticeable cervical scar. Copyright © 2014 Mosby, Inc. All rights reserved.

    Abstract In patients with phenylketonuria (PKU) compliant to diet greater tendency to overweight and higher inflammatory biomarkers levels than controls were reported. Although this could lead to atherogenesis, the elastic properties of large arteries in PKU patients have never been assessed. The aim of this study was to assess arterial stiffness measured by applanation tonometry in PKU patients compared to healthy controls. We carried out a cross-sectional study in 41 PKU patients (range age: 6–50 years old) and 41 age- and gender-matched healthy controls. Evaluated data included pharmacological treatment with sapropterin, clinical, and biochemical parameters. Aortic stiffness was assessed noninvasively by applanation tonometry measuring central blood pressure, aortic augmentation index (Aix@HR75), augmentation pressure (AP), and pulse wave velocity (PWV). We found higher PWV in classic PKU patients (6.60 m/second vs 5.26 m/second; P: .044). Percentage of PKU patients with PWV above 90 percentile was higher than controls (14.63% vs 2.32%; P: .048). A positive relationship was observed between the annual Phe median and PWV (r: 0.496; P: .012). PKU subjects with lower Phe tolerance showed more body weight (67.6 kg vs 56.8 kg; P: .012) and more PWV than those with higher Phe tolerance (6.55 m/second vs 5.42 m/second; P: .044). Our data show increased aortic stiffness in PKU patients, measured by applanation tonometry, when compared to healthy controls. Higher Phe levels are associated with a bigger PWV increase, which is not present in those subjects compliant to diet or under sapropterin treatment. These results could have marked effects in both research and clinical daily practice for a proper evaluation of cardiovascular risk in PKU subjects. PMID:29390507

    The purpose of this study was to evaluate the usefulness of 99m Tc DMSA scintigraphy on the diagnosis of a renal scar in children with urinary tract infections. Eighty three patients were included in this study, who were diagnosed as the urinary tract infection on the basis of symptom, urinalysis and urine culture. 99m Tc DMSA scintigraphy and voiding cystoureterography were performed within 7days before the treatment in all patients. We classified the scintigraphic findings as follow s : 1 ; a large hypoactive upper of lower pole. 2 ; a small hypoactive area. 3 ; single defect resulting in localized deformity of the outlines. 4 ; deformed outlines in a small or normal sized kidney. 5 ; multiple defects. 6 ; diffuse hypoactive kidney without regional impairment. Follow-up scintigraphy was done at least 6 months after the initial study. When the abnormality on the initial scintigraphy was not completely resolved on the follow-up scan, the lesion was defined as containing a scar. One hundred and fifteen renal units of 166 units(69.3%) showed abnormal findings on the DMSA scintigraphy. 65 units(56.5%) was diagnosed as containing renal scars in follow-up scintigraphies. Incidences of renal scar among renal units showing pattern 3, 4 and 5 on the initial scan was 75%, 78% and 78%, respectively. Whereas many of renal units showing 1, 2 and 6 pattern were recovered(65%, 76%, 50%). Sensitivity, specificity and accuracy of pattern-based DMSA scintigraphic findings on the diagnosis of renal scar was 76.9%, 85.1% and 81.9%, respectively. VUR was significantly associated with the renal scar when the initial DMSA shows unrecoverable findings(pattern 3, 4, 5). Odds ratio of the renal scar in a kidney showing unrecoverable initial scintigraphic findings was 19.1. Odds ratio in a kidney with mild or moderate-to-severe VUR was 3.5 and 14.4 respectively. In the urinary tract infection, renal scar was significantly developed in a kidney showing unrecoverable findings on the initial

    contracture to wrist crease was measured before treatment, at the termination of treatment, and 1 month after the termination of treatment. Scar condition was assessed with the Vancouver Scar Scale (VSS) before treatment and 1, 3, and 6 month(s) after the termination of treatment. Before treatment and 1 month after the termination of treatment, the range of motion was measured with the Total Active Movement (TAM) method; band function was evaluated by the Jebsen Test of Hand Function (JTHF), and the completion time was recorded. Data were processed with analysis of variance, LSD-t test, and t test. Twenty-four patients with 27 affected hands were treated with scheme A + B; 5 patients with 7 affected hands were treated with method C exclusively; 2 patients with 3 affected hands were treated with scheme A + B + C; 1 patient with 2 affected hands were treated with scheme C + A + C. During the course of treatment, no complication such as infection or slicing of tissue was observed, but there was a slight shifting of U-shaped Kirschner wire in 14 affected hands of 13 patients. Tendency of recurrence of scar contracture was observed in 11 affected hands of 10 patients, but the scar contracture did not reoccur after treatment with orthosis. The skin length of palmar side was respectively (131.8 ± 9.8) and (127.6 ± 7.5) mm at the termination of treatment and 1 month after, and they were both significantly longer than that before treatment [(114.5 ± 2.4) mm, with values respectively 10.71 and 10.39, P values below 0.001]. The score of VSS was respectively (9.8 ± 2.4), (9.7 ± 1.7), (9.3 ± 0.8), and (7.7 ± 0.5) points before treatment and 1, 3, and 6 month(s) after the termination of treatment. Only the score at 6 months after the termination of treatment was significantly lower than that before treatment (t = 3.28, P burn can lengthen the contracted tissue, and it is beneficial for the restoration of function and appearance of affected hand.

    Immobility in older patients is a costly problem for both patients and healthcare workers. The Hierarchical Assessment of Balance and Mobility (HABAM) is a clinical tool able to assess immobile patients and predict morbidity, yet could become more reliable and informative through automation. This paper proposes an algorithm to automatically determine which of three enacted HABAM scores (associated with bedridden patients) had been performed by volunteers. A laptop was used to gather pressure data from three mats placed on a standard hospital bed frame while five volunteers performed three enactments each. A system of algorithms was created, consisting of three subsystems. The first subsystem used mattress data to calculate individual sensor sums and eliminate the weight of the mattress. The second subsystem established a baseline pressure reading for each volunteer and used percentage change to identify and distinguish between two enactments. The third subsystem used calculated weight distribution ratios to determine if the data represented the remaining enactment. The system was tested for accuracy by inputting the volunteer data and recording the assessment output (a score per data set). The system identified 13 of 15 sets of volunteer data as expected. Examination of these results indicated that the two sets of data were not misidentified; rather, the volunteers had made mistakes in performance. These results suggest that this system of algorithms is effective in distinguishing between the three HABAM score enactments examined here, and emphasizes the potential for pervasive computing to improve traditional healthcare.

    Full Text Available Cutaneous scarring is common after trauma, surgery and infection and occurs when normal skin tissue is replaced by fibroblastic tissue during the healing process. The pathophysiology of scar formation is not yet fully understood, although the degree of tension across the wound edges and the speed of cell growth are believed to play central roles. Prevention of scars is essential and can be achieved by attention to surgical techniques and the use of measures to reduce cell growth. Grading and classifying scars is important to determine available treatment strategies. This article presents an overview of the current therapies available for the prevention and treatment of scars. It is intended to be a practical guide for surgeons and other health professionals involved with and interested in scar management.

    Across health services, there is a drive to respond to patient feedback and to incorporate their views into service improvement. The SERVQUAL method has been used in several clinical settings to quantify whether services meet patient expectations. However, work has been limited in the obstetric population. This paper seeks to address these issues. This study used an adapted SERVQUAL questionnaire to assess a reconfigured antenatal clinic service. The most important care aspects, as rated by patients, were used to construct the SERVQUAL questions. The questionnaire was administered to eligible women in two parts. The first was completed before their first hospital antenatal appointment and the second either at home (a postal-chasing exercise) or while waiting for their next appointment. Only fully completed questionnaires (both parts) were analysed. Service strengths included staff politeness, patient respect and privacy. Areas for improvement included hand cleanliness, women's involvement in decision making and communicating risk. However, the low variability in patient responses makes concrete conclusions difficult and methodological issues complicate evaluating hand cleanliness. The new antenatal clinic service received low negative weighted and un-weighted overall scores. The SERVQUAL measure was developed from patient feedback and used to further improve services. The SERVQUAL-based measure allowed an internal evaluation of patient experience and highlighted areas for improvement. However, without validation, the questionnaire cannot be used as an outcome measure and variation between published SERVQUAL questionnaires makes comparisons difficult. This highlights an important balance in patient evaluation measures--between locally responsive and externally comparable. The SERVQUAL approach allows healthcare teams to evaluate patient experience, while accounting for variation in their expectations and priorities. The study highlights several areas that are

    Full Text Available Introduction: There is a paucity of studies on the use of chemical peels for acne scars among the Asian population. A trichloroacetic acid (TCA and Jessner′s combination chemical peel, originally described by Monheit, is said to be better than a TCA peel alone. Aims: The aim of the study was to compare the efficacy of 20% TCA and Jessner′s solution versus 20% TCA alone for the treatment of acne scars. Materials and Methods : The patients were divided into two groups of 25 patients each. Chemical peeling was done in both the groups. In Group I, chemical peeling with Jessner′s peel followed by 20% TCA was done and in Group II patients chemical peeling with 20% TCA peel alone was done. Results: In Group I (Jessner′s peel and 20% TCA, mild improvement of acne scars was seen in 8% cases, moderate improvement in 32% cases and marked improvement of acne scars was seen in 60% patients. In Group II (20% TCA, mild improvement of acne scars was seen in 32% cases, moderate improvement in 40% cases and marked improvement of acne scars was seen in 28% patients. But, the difference in improvement of acne scars was not statistically significant in both the groups (P value > 0.05.

    Acute pyelonephritis (APN) is one of the most common causes of serious bacterial infection in infants. Renal scarring is the most prevalent long-term complication. To review the incidence of renal scarring within 6 months after an episode of APN in children under 36 months and its relationship with imaging studies, clinical settings, and bacteriology. A retrospective study of previously healthy patients aged one to 36 months, admitted for a first episode of APN, with a minimum follow-up of 6 months. Demographic and clinical variables were collected along with bacteriology, renal and bladder ultrasound scan, voiding cystourethrography, DMSA-scintigraphy, and re-infection events. A total of 125 patients were included in the study, of which 60% were male, the large majority (92%) febrile, and due to E. coli (74.6%). There was a history of prenatal ultrasound scan changes in 15.4%. Ultrasound scan found dilation of the urinary tract in 22.1%. Voiding cystourethrography was performed on 70 patients: 54.3% no abnormalities, 12.8% vesicoureteral reflux (VUR) grade i-iii, and 32.9% iv-v grade VUR. Six patients had iv-v grade VUR with a normal ultrasound scan. Adherence to DMSA-scintigraphy at 6 months was only 61% of that indicated. Renal scarring was found in 44.3% of those in which it was performed (60 cases). Almost half (44%) DMSA-scintigraphy in children aged one to 36 months hospitalised for APN show renal scarring at 6 months, which was found to be associated with the re-infection events and the iv-v grade VUR. There was no relationship between scarring and the bacteriology or the elevations of inflammatory biochemical markers. Copyright © 2015 Asociación Española de Pediatría.

    We investigate scarred resonances of a stadium-shaped chaotic microcavity. It is shown that two components with different chirality of the scarring pattern are slightly rotated in opposite ways from the underlying unstable periodic orbit, when the incident angles of the scarring pattern are close to the critical angle for total internal reflection. In addition, the correspondence of emission pattern with the scarring pattern disappears when the incident angles are much larger than the critical angle. The steady probability distribution gives a consistent explanation about these interesting phenomena and makes it possible to expect the emission pattern in the latter case

    Keloids and hypertrophic scars are prevalent disabling conditions with still suboptimal treatments. Basic science and molecular-based medicine research has contributed to unravel new bench-to-bedside scar therapies, and to dissect the complex signaling pathways involved. Peptides such as transforming growth factor beta (TGF-β) superfamily, with SMADs, Ski, SnoN, Fussels, endoglin, DS-Sily, Cav-1p, AZX100, thymosin-β4 and other related molecules may emerge as targets to prevent and treat keloids and hypertrophic scars. The aim of this review is to describe the basic complexity of these new molecular scar management strategies, and point out new fibrosis research lines. PMID:24438742

    Malnutrition is a common problem among cancer patients, usually occurs due to poor appetite, low food intake, and changes in body metabolism. The aim of this study is to determine the prevalence of malnutrition in patients receiving chemotherapy on an outpatient basis. This cross-sectional study conducted on 300 cancer patients referred to hospital. The prevalence of malnutrition among patients was assessed using the abridged scored patient-generated subjective global assessment (abPG-SGA) standard questionnaire. Moreover, patient's weight and 24 h dietary recall were measured. Descriptive statistics were used to present characteristics of patients and dietary recalls. For revealing the correlation, Spearman correlation was used. The average abPG-SGA score was 7.6 (standard deviation [SD] = 5.4) and 60.7% of patients were malnourished and required nutritional intervention. Patients mean age and mean duration of illness were 54.2 (SD = 14.7(years, 25 months, respectively. The most common complaint of patients included fatigue (51.3%), anorexia (43.3%), and dry mouth (41%). Reduction in food intake in past month was reported by 41.7% of patients. According to the high prevalence of cancers and increasing growth of them in recent years with regard to outpatient treatment development for cancer patients, using the abPG-SGA standard questionnaire by nutritionist or nurses can be effective to detect malnourished patients and reduce complications caused by disease.

    Full Text Available Background: There is no gold standard technique for umbilical hernia repair .Conventional open umbilical hernia repair often produces an undesirable scar. Laparoscopic umbilical hernia repair requires multiple incisions beyond the umbilicus, specialized equipments, and expensive tissue separating mesh. We describe our technique of open umbilical hernia repair utilizing a small incision. The technique was derived from our experience with single incision laparoscopy. We report the technical details and short term results. Methods: This is a retrospective analysis of the first 20 patients who underwent minimal incision scar-less open umbilical hernia repair, from June 2011 to February 2014. A single intra-umbilical curved incision was used to gain access to the hernia sac. Primary suture repair was performed for defects upto 2cm.Larger defects were repaired using an onlay mesh. In patients with a BMI of 30 kg/m2 or greater, onlay mesh hernioplasty was performed irrespective of the defect size.Results: A total of 20 patients, 12 males and 8 females underwent the procedure. Mean age was 50 (range 29 - 82 years. Mean BMI was 26.27 (range 20. -33.1 kg/m2. Average size of the incision was 1.96 range (1.5 to 2.5 cm. Mesh hernioplasty was done in 9 patients. 11 patients underwent primary suture repair alone. There were no postoperative complications associated with his technique. Average post operative length of hospital stay was 3.9 (range 2-10 days. Mean follow-up was 29.94 months, (2 weeks to 2.78 years. On follow up there was no externally visible scar in any of the patients. There were no recurrences on final follow up. Conclusion: This technique provides a similar cosmetic effect as obtained from single port laparoscopy. It is easy to perform safe, offers good cosmesis, does not require incisions beyond the umbilicus and cost effective, with encouraging results on short term follow up. Further research is needed to assess the true potential of the

    Patients increasingly use the Internet to access information related to their disease, but poor health literacy is known to impact negatively on medical outcomes. Multiple agencies have recommended that patient-oriented literature be written at a fourth- to sixth-grade (9-12 years of age) reading level to assist understanding. The readability of online patient-oriented materials related to ophthalmic diagnoses is not yet known. To assess the readability of online literature specifically for a range of ophthalmic conditions. Body text of the top 10 patient-oriented websites for 16 different ophthalmic diagnoses, covering the full range of ophthalmic subspecialties, was analyzed for readability, source (United Kingdom vs non-United Kingdom, not for profit vs commercial), and appropriateness for sight-impaired readers. Four validated readability formulas were used: Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and Gunning Fog Index (GFOG). Data were compared with the Mann-Whitney test (for 2 groups) and Kruskal-Wallis test (for more than 2 groups) and correlation was assessed by the Spearman r. None of the 160 webpages had readability scores within published guidelines, with 83% assessed as being of "difficult" readability. Not-for-profit webpages were of significantly greater length than commercial webpages (P = .02) and UK-based webpages had slightly superior readability scores compared with those of non-UK webpages (P = .004 to P readability formula used). Of all webpages evaluated, only 34% included facility to adjust text size to assist visually impaired readers. To our knowledge, this is the first study to assess readability of patient-focused webpages specifically for a range of ophthalmic diagnoses. In keeping with previous studies in other medical conditions, we determined that readability scores were inferior to those recommended, irrespective of the measure used.

    Full Text Available Objective: Psychiatric rehabilitation has gained significance owing to improved healthcare facilities for burn injuries and decreased mortality/ morbidity rates. Burn traumas may result in psychiatric signs such as denial, anger, guilt, confusion, disgrace, anxiety, distress, and nervousness. Psychiatric disorders such as delirium, depression, anxiety, post-traumatic stress disorder, and sexual problems can also be encountered. Therefore, it is necessary to look for these signs and disorders through regular sessions with burn patients and appropriate psychometric tests. This study aims at examining the process of psychological rehabilitation for burn patients in light of the current literature. Material and Methods: This study has been carried out in the light of the main and current literature review. The study intends to put forth the data observed in the course of the psychological diagnosis, treatment and rehabilitation of burn patients. The study has been conducted in accordance with the Helsinki Declaration Guidelines. Results: Treatment and rehabilitation process requires a multidisciplinary teamwork that consists of physicians, dieticians, psychologists, social service specialists, and other healthcare workers who can meet the needs of burn patients and their families. It is necessary for the team to contribute both to the hospitalization process and the social environment of the patients and their families. Conclusion: It is observed that the quality of life of these patients can be considerably improved with the effective assessment of psychiatric signs that occur during or after the injury and with appropriate treatment methods.

    We describe three cases of hair loss in a female pattern hair loss (FPHL) distribution with histologic features of lichen planopilaris (LPP). All patients had a history of diffuse, gradual hair loss in a Christmas tree pattern that clinically presented as FPHL on gross and dermoscopic examination. Notably, there were no characteristic clinical signs of LPP and no histologic features of FPHL. These cases are most consistent with cicatricial pattern hair loss (CPHL). This relatively new entity is similar to fibrosing alopecia in a pattern distribution (FAPD) in that they are both scarring alopecias confined to a FPHL distribution, but CPHL lacks the clinical signs of perifollicular erythema and perifollicular keratosis seen in FAPD. These three cases may present an early, subtle form of CPHL and will be of interest to clinicians and histopathologists alike. © 2017 The Australasian College of Dermatologists.

    Urethral stricture disease is increasingly common occurring in about 1% of males over the age of 55. The stricture tissue is rich in myofibroblasts and multi-nucleated giant cells which are thought to be related to stricture formation and collagen synthesis. An increase in collagen is associated with the loss of the normal vasculature of the normal urethra. The actual incidence differs based on worldwide populations, geography, and income. The stricture aetiology, location, length and patient's age and comorbidity are important in deciding the course of treatment. In this review we aim to summarise the existing knowledge of the aetiology of urethral strictures, review current treatment regimens, and present the challenges of using tissue-engineered buccal mucosa (TEBM) to repair scarring of the urethra. In asking this question we are also mindful that recurrent fibrosis occurs in other tissues-how can we learn from these other pathologies?

    To analyze the clinical features, diagnosis and treatment of gestational trophoblastic diseases in cesarean scar. Clinical data of three cases of gestational trophoblastic diseases in cesarean scar diagnosed in Women's Hospital, Zhejiang University School of Medicine during December 2011 and December 2016 were collected. And literature search was performed in Wanfang data, VIP, CNKI, PubMed, ISI Web of Knowledge and EMbase database. A total of 20 cases of gestational trophoblastic diseases were included in the analysis. Clinical features were mainly abnormal vaginal bleeding after menopause, artificial abortion or medical abortion, which might be accompanied by abdominal pain. Serum β-human chorionic gonadotropin (β-hCG) levels were increased in 19 patients. The sonographic features were increase of uterine volume, honeycomb-like abnormal intrauterine echo (or described as multiple cystic dark area, multiple anechoic area and multiple liquid dark area) or heterogeneity echo conglomeration, and no clear bound with muscular layer in some cases. There were abundant blood flow signals inside or around the lesions. The ultrasonography indicated that the lesions were located in the anterior side of the uterine isthmus with the involvement of cesarean section scar. In 12 cases with lesions in cesarean scar shown by preliminary diagnosis, 9 underwent uterine artery embolization (UAE) for pretreatment; the blood loss greater than 1500 mL was observed in only one case without UAE; no patient received hysterectomy. In 8 patients whose lesions were not shown in cesarean scar, only one case received UAE pretreatment, and hysterectomy was performed in 3 cases due to blood loss greater than 1500 mL. Two cases were lost in follow-up and no death was reported in remaining 18 cases. The serum β-hCG levels returned to normal or satisfactory level during the follow-up in 17 cases with increased β-hCG levels before treatment and no recurrence was observed.

    Cervical scar contracture causes both physical and psychological distress for burn patients. Many pedicle flaps or skin grafting have been suggested for reconstruction of cervical scar contracture with variable results in the literature. The authors present the axial thoracic flap based on the thoracic branch of the supraclavicular artery (TBSA) for reconstruction of cervical scar contracture. Postburn scar contractures in anterior neck region of 66 patients had been reconstructed with the axial pattern thoracic flaps based on the TBSA, including 1 expanded and 10 nonexpanded pedicle flaps, and 9 expanded and 46 nonexpanded island pedicle flaps, during 1988 through 2012. After removing and releasing the cervical scar contracture, the flap was designed in the thoracic region. The axial artery of the flap is the TBSA bifurcating from the intersection point of sternocleidomastoid muscle and omohyoid muscle with several concomitant veins as the axial veins. The flap can be designed in a large area within the borders of the anterior border of the trapezius muscle superiorly, the middle part of the deltoid muscle laterally, the midsternal line medially, and the level 3 to 4 cm below nipples inferiorly. After incisions were made along the medial, inferior, and lateral border, dissection was performed toward the pedicle. Donor site was closed directly in expanded cases and with skin grafting in nonexpanded cases. Cervical scar contractures were repaired with good functional and cosmetic results in 64 cases among this cohort. Flap tip necrosis in other 2 cases, caused by postoperative hematoma, was repaired by skin grafting. The color and texture of all flaps were fitted with those of the surrounding skin. The donor sites all healed primarily. The flap sensation in the thoracic region regained in the early stage postoperatively and that in cervical area recovered completely after 6 months according to the report of the patients. With reliable blood supply based on the

    Background. Gadolinium-enhanced MRI has recently been employed in the diagnosis of acute pyelonephritis. Its potential utility in the diagnosis of renal scars in children is unknown. Objective. To evaluate the potential utility of MRI using fat-saturated T1-weighted (T1-W) and post-gadolinium, short-tau inversion-recovery (STIR) sequences in detecting renal scarring by comparison with technetium dimercaptosuccinic acid ({sup 99} {sup m}Tc-DMSA) renal scintigraphy in children at risk of renal scarring. Materials and methods. A group of 24 children with spina bifida and neurogenic bladder or anorectal anomaly was studied. No patient had a history of acute pyelonephritis.

    Cross-linked hyaluronic acid-based fillers have gained rapid acceptance for treating facial wrinkles, deep tissue folds and sunken areas due to aging. This study evaluates, in addition to space-filling properties, their effects on softness and elasticity as a secondary effect, following injection of 3 commercially available cross-linked hyaluronic acid-based fillers (15mg/mL, 17,5mg/mL and 20mg/mL) in patients presenting with congenital or acquired facial malformations. We started injecting gels of cross-linked hyaluronic acid-based fillers in those cases in 2013; we performed 46 sessions of injections in 32 patients, aged from 13-32. Clinical assessment was performed by the patient himself and by a plastic surgeon, 15 days after injections and 6-18 months later. Cross-linked hyaluronic acid-based fillers offered very subtle cosmetic results and supplemented surgery with a very high level of satisfaction of the patients. When injected in fibrosis, the first session enhanced softness and elasticity; the second session enhanced the volume. Cross-linked hyaluronic acid-based fillers fill sunken areas and better softness and elasticity of scar tissues. In addition to their well-understood space-filling function, as a secondary effect, the authors demonstrate that cross-linked hyaluronic acid-based fillers improve softness and elasticity of scarring tissues. Many experimental studies support our observations, showing that cross-linked hyaluronic acid stimulates the production of several extra-cellular matrix components, including dermal collagen and elastin.

    AbstractWe evaluated a new trachoma scarring ranking system with potential use in clinical research. The upper right tarsal conjunctivas of 427 individuals from Ethiopian villages with hyperendemic trachoma were photographed. An expert grader first assigned a scar grade to each photograph using the 1981 World Health Organization (WHO) grading system. Then, all photographs were ranked from least (rank = 1) to most scarring (rank = 427). Photographic grading found 79 (18.5%) conjunctivae without scarring (C0), 191 (44.7%) with minimal scarring (C1), 105 (24.6%) with moderate scarring (C2), and 52 (12.2%) with severe scarring (C3). The ranking method demonstrated good internal validity, exhibiting a monotonic increase in the median rank across the levels of the 1981 WHO grading system. Intrarater repeatability was better for the ranking method (intraclass correlation coefficient = 0.84, 95% CI = 0.74-0.94). Exhibiting better internal and external validity, this ranking method may be useful for evaluating the difference in scarring between groups of individuals.

  14. Collagen-binding peptidoglycans inhibit MMP mediated collagen degradation and reduce dermal scarring.

    Directory of Open Access Journals (Sweden)

    Kate Stuart

    Full Text Available Scarring of the skin is a large unmet clinical problem that is of high patient concern and impact. Wound healing is complex and involves numerous pathways that are highly orchestrated, leaving the skin sealed, but with abnormal organization and composition of tissue components, namely collagen and proteoglycans, that are then remodeled over time. To improve healing and reduce or eliminate scarring, more rapid restoration of healthy tissue composition and organization offers a unique approach for development of new therapeutics. A synthetic collagen-binding peptidoglycan has been developed that inhibits matrix metalloproteinase-1 and 13 (MMP-1 and MMP-13 mediated collagen degradation. We investigated the synthetic peptidoglycan in a rat incisional model in which a single dose was delivered in a hyaluronic acid (HA vehicle at the time of surgery prior to wound closure. The peptidoglycan treatment resulted in a significant reduction in scar tissue at 21 days as measured by histology and visual analysis. Improved collagen architecture of the treated wounds was demonstrated by increased tensile strength and transmission electron microscopy (TEM analysis of collagen fibril diameters compared to untreated and HA controls. The peptidoglycan's mechanism of action includes masking existing collagen and inhibiting MMP-mediated collagen degradation while modulating collagen organization. The peptidoglycan can be synthesized at low cost with unique design control, and together with demonstrated preclinical efficacy in reducing scarring, warrants further investigation for dermal wound healing.

    Acceptable scar positioning on the anterior male chest is very limited. In Gynecomastia surgery, an obvious areolar incision is the most sensitive indicator of a previous operation; a less apparent scar is indispensable for the patient's psychological satisfaction. Whenever only areolar diameter reduction is required, the circumareolar incision must be performed in a position leaving the least conspicuous scar. Standard excision of an outer doughnut of areolar skin results in a visible and unnatural peri-areolar scar. The peri-nipple excision of areolar skin leaves the skin-areola junction undisturbed. When combined with a transverse areolar infra-nipple incision, access for subcutaneous mastectomy is facilitated. With this approach, risk of nipple vascular compromise is thought to be reduced, and necrosis of areolar pigmented skin virtually impossible.

    2010-12-01

    A 36-year-old Caucasian female of Iranian origin presented with a persistently raised dermal lesion under her chin, confirmed histologically to be a keloid scar. There was a 4-year history of a negative response to a range of conventional treatments including topical silicone gel sheets, steroid creams, steroid injections and surgical excision. In view of treatment failure and an in vitro study indicating a positive effect of photodynamic therapy (PDT)on keloid fibroblasts, we treated our patient's lesion with five sessions of methyl aminolevulinate photodynamic therapy (MAL-PDT) over a period of 5 months. Following this treatment regime, her keloid scar had considerably reduced in size and become flattened.The surface of the keloid also became smooth, with attenuation in erythema at the margin as well as an improvement in the colour of the scar, which was better matched to the surrounding skin. There was no recurrence at 1-year follow-up and this treatment resulted in an overall acceptable cosmetic outcome. This case report presents PDT as a potential treatment option for persistent keloid lesions unresponsive to conventional scar modulation therapies and suggests a need for further research in this area.

    Full Text Available Zhouna Li, Zhehu Jin Department of Dermatology, Yanbian University Affiliated hospital, Yanji, Jilin, People’s Republic of China Background: Keloids and hypertrophic scars are the most common types of pathological scarring. Traditionally, keloids have been considered as a result of aberrant wound healing, involving excessive fibroblast participation that is characterized by hyalinized collagen bundles. However, the usefulness of this characterization has been questioned. In recent years, studies have reported the appropriate use of verapamil for keloids and hypertrophic scars.Methods: Searches were conducted on the databases Medline, Embase, Cochrane, PubMed, and China National Knowledge Infrastructure from 2006 to July 2016. State12.0 was used for literature review, data extraction, and meta-analysis. Treatment groups were divided into verapamil and nonverapamil group. Nonverapamil group includes steroids and intense pulsed light (IPL therapy. Total effective rates include cure rate and effective rate. Cure: skin lesions were completely flattened, became soft and symptoms disappeared. Efficacy: skin lesions subsided, patient significantly reduced symptoms. Inefficient definition of skin was progression free or became worse. Random-effects model was used for the meta-analysis.Results: Six studies that included 331 patients with keloids and hypertrophic scars were analyzed. Analysis of the total effective rate of skin healing was performed. The total effective rates in the two groups were 54.07% (verapamil and 53.18% (nonverapamil, respectively. The meta-analysis showed that there was no difference between the two groups. We also compared the adverse reactions between the verapamil treatment group and the steroids treatment group in two studies, and the result indicated that the verapamil group showed less adverse reactions.Conclusion: There were no differences between the application of verapamil and nonverapamil group in keloids and

  18. Cardiovascular risk assessment in hypertensive patients

    Directory of Open Access Journals (Sweden)

    Elaine Amaral de Paula

    Full Text Available OBJECTIVE: to assess cardiovascular risk by means of the traditional Framingham score and the version modified through the incorporation of emerging risk factors, such as family history of acute myocardial infarction, metabolic syndrome and chronic kidney disease. METHOD: participants were 50 hypertensive patients under outpatient treatment. The clinical data were collected through a semi-structured interview and the laboratory data from patients' histories. RESULTS: it was verified that the traditional Framingham score was predominantly low (74%, with 14% showing medium risk and 12% high risk. After the inclusion of emerging risk factors, the chance of a coronary event was low in 22% of the cases, medium in 56% and high in 22%. CONCLUSIONS: the comparison between the traditional Framingham risk score and the modified version demonstrated a significant difference in the cardiovascular risk classification, whose correlation shows discreet agreement between the two scales. Lifestyle elements seem to play a determinant role in the increase in cardiovascular risk levels.

    The present study intended to evaluate the nutritional status of Portuguese colorectal patients and associated it with surgery type as well as quality of life outcomes. Malnutrition can affect up to 85% of cancer patients and specifically 30-60% in colorectal cancer and can significantly influence health outcomes. A sample of 50 colorectal cancer patients was evaluated in what refers to several anthropometric measures, food intake, clinical history, complications rate before and after surgery procedure. The sample was divided between convention and fast-track procedures. Most of the individuals were overweight or obese but had lost weight on the past six months. Despite mild, there were signs of malnutrition in this sample with high losses of fat free mass, weight and also fat mass during the hospitalization period. These results reinforce the importance of malnutrition assessment in colorectal patients as well as consider weight loss on the past months and body composition in order to complement nutritional status evaluation.

  1. Prognostic Assessment in Patients with Hepatic Encephalopathy

    Directory of Open Access Journals (Sweden)

    Rita García-Martínez

    2011-01-01

    Full Text Available Hepatic encephalopathy (HE is a common complication of liver failure that is associated with poor prognosis. However, the prognosis is not uniform and depends on the underlying liver disease. Acute liver failure is an uncommon cause of HE that carries bad prognosis but is potentially reversible. There are several prognostic systems that have been specifically developed for selecting patients for liver transplantation. In patients with cirrhosis the prognosis of the episode of HE is usually dictated by the underlying precipitating factor. Acute-on-chronic liver failure is the most severe form of decompensation of cirrhosis, the prognosis depends on the number of associated organ failures. Patients with cirrhosis that have experienced an episode of HE should be considered candidates for liver transplant. The selection depends on the underlying liver function assessed by the Model for End-stage Liver Disease (MELD index. There is a subgroup that exhibits low MELD and recurrent HE, usually due to the coexistence of large portosystemic shunts. The recurrence of HE is more common in patients that develop progressive deterioration of liver function and hyponatremia. The bouts of HE may cause sequels that have been shown to persist after liver transplant.

  2. Semiclassical scar functions in phase space

    2007-01-01

    We develop a semiclassical approximation for the scar function in the Weyl-Wigner representation in the neighborhood of a classically unstable periodic orbit of chaotic two-dimensional systems. The prediction of hyperbolic fringes, asymptotic to the stable and unstable manifolds, is verified computationally for a (linear) cat map, after the theory is adapted to a discrete phase space appropriate to a quantized torus. Characteristic fringe patterns can be distinguished even for quasi-energies where the fixed point is not Bohr-quantized. Also the patterns are highly localized in the neighborhood of the periodic orbit and along its stable and unstable manifolds without any long distance patterns that appear for the case of the spectral Wigner function

    It is often difficult to expose the pulmonary artery buried in a scar tissue, especially in lung cancer patients that responded well to neoadjuvant chemoradiotherapy. Difficulty to access pulmonary artery branches may lead to potentially unnecessary pneumonectomy. To complete lobectomy in such cases, a technique with preceding bronchial cutting for exposure of the pulmonary artery is presented. After dissecting the pulmonary vein, the lobar bronchus is cut from the opposite side of the pulmonary artery with scissors. The back wall of the lobar bronchus is cut using a surgical knife from the luminal face, which can expose the pulmonary artery behind the bronchial stump and then complete lobectomy. Fourteen patients have been treated using the present technique, enabling complete resection by lobectomy (including sleeve lobectomy in 3 patients) without major bleeding. The present procedure can expose pulmonary artery buried in scar tissue, resulting in making the lobectomy safer.

    Laser therapies are used prophylactically for excessive scar formation. The Laser-Assisted Skin Healing treatment induces a controlled heat stress that promotes tissue regeneration. This comparative trial is the first to evaluate the performance of a new automated 1210-nm laser system, compatible with all Fitzpatrick scale phototypes. Forty women undergoing bilateral breast reduction were enrolled in this double-blinded randomized controlled trial. The horizontal sutured incision of one breast was treated with the portable 1210-nm laser while in the operating theatre. The other breast was used as the study control. Objective measurements, subjective clinical assessments and safety evaluation were carried out over 1 year by both clinicians and patients. Six weeks following surgery, better overall appearance and modified OSAS scores were reported for the laser-treated scars when compared to the control group (p = 0.024 and p = 0.079). This supports an early effect of the laser treatment during the inflammatory stage of the healing process. After a post-treatment period of 6 months, there continued to be a strong tendency in favour of the laser treatment based on the subjective scores and corroborated by the objective improvement of the treated scar volume (p = 0.038). At 1 year, the laser-treated scars continued to improve compared to the control ones in terms of volume (p = 0.004), surface (p = 0.017) and roughness (p = 0.002), and these comparatively better results were strengthened with the blind expression of patients' preference for their laser-treated scar (p = 0.025). This new 1210-nm laser treatment, used as a single session performed immediately after surgery, provides significant objective and subjective improvements in scar appearance. These data can be useful when preparing patients to undergo their surgical procedure. This journal requires that authors assign a level of evidence to each article.

    The skin paddle of the latissimus dorsi flap is typically inset horizontally (HILD) in breast reconstruction. We describe our experience with the vertical inset of the latissimus dorsi (VILD) and its aesthetic benefit. We performed a case-control study comparing the most recent cases of both VILD and HILD. Scar, as seen on anterior-posterior photographs, was digitally measured and compared from 3 clinically relevant areas: (1) all visible scarring ("mirror view"), (2) scarring above the nipple ("self-view"), and (3) scarring above or medial to the nipple ("social view"). Demographics and outcomes were statistically compared. Fifty of the most recent patients receiving HILD or VILD were selected for each group. Average patient age was 55.6 and 51.6 years (P = 0.32), and average follow-up was 531.6 and 606.7 days (P = 0.20), respectively. The VILD scar-length ratios were decreased by 17% in the mirror view (P ≤ 0.01), 37% in the self-view (P ≤ 0.01), and 37% in the social view (P ≤ 0.01). There were no statistically significant differences between groups regarding smoking (P = 0.75), diabetes (P = 0.70), body mass index (P = 0.74), seroma (P = 0.46), infection (P = 1.0), or flap necrosis (P = 0.70). The VILD is safe and reliable. Measurements from anterior-posterior photographs illustrate statistically significant decreases in overall scar burden (mirror view) and statistically significant reductions in the highly visible self-view and social view. Our study is the first to quantify a reduction in scar burden by using VILD technique.

    Full Text Available BackgroundFractional CO2 laser is an effective treatment for scars, but most patients complain about sharp burning pain, even after the application of lidocaine ointment. This study analyzed the impact of a vibrating device to nonpharmacologically reduce the acute pain of laser treatment, in accordance with the gate control theory of pain management.MethodsThis is a prospective study performed from May 2013 through March 2014. Fifty-three patients (mean age, 26.7 years; range, 16–44 years who had donated livers for liver transplantation were treated with a fractional CO2 laser (10,600 nm; model eCO2, Lutronic Corp for their abdomen scars. Laser treatment was applied 4 months after surgery. A commercially available, locally applied vibrating device (model UM-30M, Unix Electronics Co. Ltd. was used, in an on-and-off pattern, together with the CO2 laser. A visual analogue scale (VAS; 0, no pain; 10, most severe pain of pain sensation was assessed and statistically analyzed using a paired t-test.ResultsThe average VAS score for pain with the vibrating device was 4.60 and the average VAS score without the vibrating device was 6.11. The average difference between scores was 1.51 (P=0.001.ConclusionsA locally applied vibrating device was demonstrated to be effective in reducing pain when treating with a fractional CO2 laser. Vibration treatment could be helpful when treating scars with fractional CO2 laser in pain-sensitive patients, particularly children.

  7. [Patient safety in antibiotics administration: Risk assessment].

    Maqueda Palau, M; Pérez Juan, E

    To determine the level of risk in the preparation and administration of antibiotics frequently used in the Intensive Care Unit using a risk matrix. A study was conducted using situation analysis and literature review of databases, protocols and good practice guidelines on intravenous therapy, drugs, and their administration routes. The most used antibiotics in the ICU registered in the ENVIN-HELICS program from 1 April to 30 June 2015 were selected. In this period, 257 patients received antimicrobial treatment and 26 antibiotics were evaluated. Variables studied: A risk assessment of each antibiotic using the scale Risk Assessment Tool, of the National Patient Safety Agency, as well as pH, osmolarity, type of catheter recommended for administration, and compatibility and incompatibility with other antibiotics studied. Almost two-thirds (65.3%) of antibiotics had more than 3 risk factors (represented by a yellow stripe), with the remaining 34.7% of antibiotics having between 0 and 2 risk factors (represented by a green stripe). There were no antibiotics with 6 or more risk factors (represented by a red stripe). Most drugs needed reconstitution, additional dilution, and the use of part of the vial to administer the prescribed dose. More than half of the antibiotics studied had a moderate risk level; thus measures should be adopted in order to reduce it. The risk matrix is a useful tool for the assessment and detection of weaknesses associated with the preparation and administration of intravenous antibiotics. Copyright © 2016 SECA.

    Incision placement and design in rhytidectomy is critical for patient satisfaction. To evaluate the aesthetic outcome of W-plasty vs traditional straight-line (SL) trichophytic closure techniques on posterior occipital hairline scars in rhytidectomy. A retrospective cohort study was conducted at the Buckingham Center for Facial Plastic Surgery. Clinical history and operative reports were reviewed for 46 patients who underwent rhytidectomy (23 using W-plasty and 23 using SL technique) between June 1, 2014 and August 31, 2015. Blinded photographic analysis of 1-year postoperative photographs was performed. The posterior occipital hairline incision was primarily closed with either a W-plasty or SL trichophytic technique. Standard photographs of the posterior occipital incision site obtained after the 1-year postoperative mark were reviewed and scored in a blinded fashion by 3 nonphysician medical staff members using a modified Manchester Scar Scale (MSS: from 0 [best possible outcome] to 24 [worst possible outcome]). Interrater reliability was assessed via Cronbach α testing. There were 23 patients in each group. The W-plasty and SL groups were similar in terms of age (mean [SD] age, 59.6 [6.3] years and 64.1 [7.3] years, respectively), sex (21 [91%] and 21 [91%] women, respectively), race-ethnicity, and absence of risk factors (smoking and diabetes) predisposing to poor wound healing (0 and 0 smoking/diabetes, respectively). Mean (SD) follow-up times for the W-plasty and SL groups were 388 (38.8) and 475 (100.1) days, respectively. No statistical difference was demonstrated in the mean aggregate MSS scores from all evaluators between the W-plasty group and the SL group (reviewer 1: 5.69 vs 5.86, P = .60; reviewer 2: 10.09 vs 9.56, P = .65; and reviewer 3: 5.30 vs 6.17, P = .08). Overall interrater reliability for the MSS scores was 0.56. Primary W-plasty and SL trichophytic closures in the posterior occipital hairline appear to yield highly acceptable

    Full Text Available Introduction. Little is known about the effects of volume change by hemodialysis (HD and mechanical stress caused by an anatomical structure being in contact with the left atrium on the progression of atrial remodeling. We experienced a case of atrial tachycardia (AT in a patient who had left atrial (LA scarring at the LA roof and a low-voltage area with slow conduction around the LA scar as components of AT circuit. Here, we present the conceivable hypothesis of the LA scar and the low-voltage area formation. Our concept can be useful in developing a strategy for ablation in a patient with chronic renal failure (CRF on HD. Case Report. A 65-year-old man with CRF on HD was referred for AT ablation. Three-dimensional electroanatomical mapping revealed that the AT conducted around an LA scar in a counterclockwise fashion. There was a slow conduction area at the superior side of the LA scar, where the AT was terminated during the ablation. Computed tomography indicated a close relationship between the LA and the anatomical structures (ascending aorta and pulmonary artery. Conclusion. Volume change by HD and close contact of anatomical structures to the LA can promote atrial remodeling, resulting in AT occurrence.

    and scarring in Guinea-Bissau. In a cohort of children born in suburban Bissau from March 2000 to July 2002, we assessed a Mantoux test with Purified protein derivative (PPD) (SSI, 2 T.U.) at 2 (2689 children), 6 (N=2148) and 12 months (N=1638) of age, and BCG scar was assessed at 2 (N=2698) and 6 months (N......=2225) of age. In a subgroup of the children the vaccination technique was monitored by direct observation of post-vaccination wheal and route of administration. Three different types of BCG vaccine supplied by the local Extended Programme on Immunization were used. At 6 months of age the rate of PPD...... reactors (>1mm) after BCG vaccination was 25% and the rate of scarring was 89%. One BCG strain was associated with fewer PPD reactors (OR=0.54 (0.31-0.91)) and BCG scars (OR=0.13 (0.05-0.37)) and larger post-vaccination wheals produced more PPD reactions (OR 1.21 (95% CI 1.02-1.43)) and BCG scars (OR 1...

    Hypertrophic scar is characterized by excessive deposits of collagen during skin wound healing, which could become a challenge to clinicians. This study assessed the effects of the extracorporeal shock wave therapy (ESWT) on hypertrophic scar formation and the underlying gene regu-lation. A rabbit ear hypertrophic scar model was generated and randomly divided into three groups: L-ESWT group to receive L-ESWT (energy flux density of 0.1 mJ/mm2), H-ESWT (energy flux density of 0.2 mJ/mm2) and sham ESWT group (S-ESWT). Hypertrophic scar tissues were then collected and stained with hematoxylin and eosin (H&E) and Masson's trichrome staining, respectively, to assess scar elevation index (SEI), fibroblast density and collagen fiber arrangement. Expression of cell proliferation marker proliferating cell nuclear antigen (PCNA) and α-smooth muscle actin (α-SMA) were assessed using RT-PCR and immunohistochemistry in hypertrophic scar tissues. H&E staining sections showed significant reduction of SEI and fibroblast density in both ESWT treatment groups compared to S-ESWT, but there was no dramatic difference between L-ESWT and H-ESWT groups. Masson's trichrome staining showed that collagen fibers were more slender and broader and oriented in parallel to skin surface after administration of ESWT compared to control tissues. At the gene level, PCNA‑positive fibroblasts and α-SMA-positive myofibroblasts were significantly decreased after L-ESWT or H-ESWT compared to the controls. Furthermore, there was no significant difference in expression of PCNA mRNA between L-ESWT or H-ESWT and S-ESWT, whereas expression of α-SMA mRNA significantly decreased in L-ESWT compared to that of H-ESWT and S-ESWT (P=0.002 and P=0.030, respectively). In conclusion, L-ESWT could be effective on suppression of hypertrophic scar formation by inhibition of scar elevation index and fibroblast density as well as α-SMA expression in hypertrophic scar tissues of the rabbit model.

    The aim of this study was to evaluate the efficacy of autologous platelet-rich plasma (PRP) combined with erbium fractional laser therapy for facial acne or acne scars. PRP combined with erbium fractional laser therapy was used for the treatment of 22 patients, including 16 patients who suffered from facial acne scars and 6 patients who suffered from acne scars concomitant with acne. Whole blood (40 ml) was collected from each patient, and following differential centrifugation, PRP was harvested. After using an erbium fractional laser, we applied PRP to the entire face of every patient. Digital photos were taken before and after the treatment for evaluation by dermatologists and the patients rated the efficacy on a 5-point scale. The erythema was moderate or mild, while its total duration was 50%, and 91% of the patients were satisfied; no acne inflammation was observed after treatment. PRP combined with erbium fractional laser therapy is an effective and safe approach for treating acne scars or acne, with minimal side-effects, and it simultaneously enhanced the recovery of laser-damaged skin.

    Sulcus vocalis and vocal fold scar involve derangement of the superficial lamina propria of the vocal fold, which results in significant dysphonia. Many options exist for treatment, most of which have unsatisfactory and unpredictable outcomes. Autologous transplantation of temporalis fascia into the vocal fold (ATFV) has the potential to be a better treatment option, but long-term outcomes have not been well studied. Retrospective chart review and patient survey. Twenty-one patients diagnosed with vocal fold scar or sulcus vocalis and treated with ATFV with at least 1-year follow-up were included. Voice Handicap Index 10 (VHI-10) questionnaires were collected preoperatively and 6 months postoperatively. Patients were reached at the time of the study to complete another VHI-10 and a Likert scale survey. The mean decrease in VHI-10 scores between preoperation and 6 months postoperation was 8.35 ( P vocal fold for the treatment of vocal fold scar and sulcus vocalis is a safe surgery with good long-term outcomes and high patient satisfaction.

    Full Text Available Hypertrophic scar is a complication of wound healing and has a high recurrence rate which can lead to significant abnormity in aesthetics and functions. To date, no ideal treatment method has been established. Meanwhile, the underlying mechanism of hypertrophic scarring has not been clearly defined. Although a large amount of scientific research has been reported on the use of medicinal plants as a natural source of treatment for hypertrophic scarring, it is currently scattered across a wide range of publications. Therefore, a systematic summary and knowledge for future prospects are necessary to facilitate further medicinal plant research for their potential use as antihypertrophic scar agents. A bibliographic investigation was accomplished by focusing on medicinal plants which have been scientifically tested in vitro and/or in vivo and proved as potential agents for the treatment of hypertrophic scars. Although the chemical components and mechanisms of action of medicinal plants with antihypertrophic scarring potential have been investigated, many others remain unknown. More investigations and clinical trials are necessary to make use of these medical plants reasonably and phytotherapy is a promising therapeutic approach against hypertrophic scars.

    Full Text Available Keloids and hypertrophic scars (HTS are the result of overgrowth of fibrous tissue, following healing of a cutaneous injury, and cause morbidity. There are several treatment modalities which are useful for the management of keloids, though no single modality is completely effective. The most commonly used modalities are pressure, silicone gel sheet, intralesional steroids, 5-fluorouracil (5 FU, cryotherapy, surgical excision, and lasers. They may be used either singly or, as is done more commonly, in combinations. Any qualified dermatologist who has attained postgraduate qualification in dermatology can treat keloids and HTS. Some procedures, such as cryosurgery and surgical excision, may require additional training in dermatologic surgery. Most modalities for keloids, including intralesional injections and mechanical therapies such as pressure and silicone gel based products, can be given/prescribed on OPD basis. Surgical excision requires a minor operation theater with the facility to handle emergencies. It is important to counsel the patient about the nature of the problem. One should realize that keloid will only improve and not disappear completely. Patients should be informed about the high recurrence rates. Different modalities carry risk of adverse effects and complications and the treating physician needs to be aware of these and patients should be informed about them.

    Collagen fibers are an essential component of the dynamic process of scarring, which accompanies various diseases. Scar tissue may reveal different morphologic expressions, such as hypertrophic scars or keloids. Collagen fibers can be visualized by fluorescent light when stained with eosin. Second Harmonic Generation (SHG) creates a non linear signal that occurs only in molecules without inversion symmetry and is particularly strong in the collagen fibers arranged in triple helices. The aim of this study was to describe the methodology for the analysis of the density and texture of collagen in keloids, hypertrophic scars and conventional scars. Samples were examined in the National Institute of Science and Technology on Photonics Applied to Cell Biology (INFABIC) at the State University of Campinas. The images were acquired in a multiphoton microscopy LSM 780-NLO Zeiss 40X. Both signals, two-photon fluorescence (TPEF) and SHG, were excited by a Mai-Tai Ti:Sapphire laser at 940 nm. We used a LP490/SP485 NDD filter for SHG, and a BP565-610 NDD filter for fluorescence In each case, ten images were acquired serially (512×512 μm) in Z-stack and joined together to one patchwork-image . Image analysis was performed by a gliding-box-system with in-house made software. Keloids, hypertrophic scars and normal scar tissue show different collagen architecture. Inside an individual case differences of the scar process may be found between central and peripheral parts. In summary, the use of nonlinear optics is a helpful tool for the study of scars tissue.

    Acne is a very common skin disease in which scars are seen in 95% of the patients. Although numerous treatments have been recommended, researchers are still searching for a single modality to treat the complication due to its variety in shape and depth. We compared the effects of fractional carbon dioxide (CO 2 ) laser alone and in combination with subcision in the treatment of atrophic acne scars. This clinical trial study was performed in Skin Diseases and Leishmaniasis Research Center (Isfahan, Iran) during 2011-2012. Eligible patients with atrophic acne scars were treated with fractional CO 2 laser alone (five sessions with 3-week interval) on the right side of the face and fractional CO 2 laser plus subcision (one session using both with four sessions of fractional CO 2 laser, with 3-week interval) on the left side. The subjects were visited 1, 2, and 6 months after the treatment. Patient satisfaction rate was analyzed using SPSS 20 software. The average of recovery rate was 54.7% using the combination method and 43.0% using laser alone ( P < 0.001). The mean patient satisfaction was significantly higher with the combination method than laser alone (6.6 ± 1.2 vs. 5.2 ± 1.8; P < 0.001). Bruising was only seen with the combination method and lasted for 1 week in 57.0% and for 2 weeks in 43.0%. Erythema was seen in both methods. Postinflammatory pigmentation and hyperpigmentation were associated with combination method. No persistent side effects were seen after 6 months. Using a combination of subcision and laser had suitable results regarding scar recovery and satisfaction rate.

    Background and Objective. Early burn scar removal is the standard of care for burn patients; excisional debridement, however, often leads to excision of dermal remnants, making autografting unavoidable. Enzymatic debridement with proteolytic enzymes enriched in Bromelain (Nexobrid®) leaves these dermal remnants to allow spontaneous healing of partial thickness burns. This study evaluates if Nexobrid® (MediWound Ltd., Israel) reduces the need for surgery and autografting in intermediate and de...

    Guilherme Karam Corrêa Leite

    Full Text Available CONTEXT AND OBJECTIVE: The incidence of scar endometrioma ranges from 0.03 to 3.5%. Certain factors relating to knowledge of the clinical history of the disease make correct diagnosis and treatment difficult. The aim here was to identify the clinical pattern of the disease and show surgical results. The literature on this topic was reviewed. DESIGN AND SETTING: Retrospective descriptive study at Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. METHODS: Data from the medical records of patients with preoperative diagnoses of scar endometrioma who underwent operations between 2001 and 2007 were surveyed and reviewed. The postoperative diagnosis came from histopathological analysis. The main information surveyed was age, obstetric antecedents, symptoms, tumor location, size and palpation, duration of complaint, diagnosis and treatment. All patients underwent tumor excision with a safety margin. RESULTS: There were 33 patients, of mean age 30.1 ± 5.0 years (range: 18-41 years. The total incidence was 0.11%: 0.29% in cesarean sections and 0.01% in vaginal deliveries. Twenty-nine tumors (87.9% were located in cesarean scars, two (6.0% in episiotomy scars and two (6.0% in the umbilical region. The main symptom was localized cyclical pain (66.7%, of mean duration 30.5 months (± 23. Surgical treatment was successful in all cases. CONCLUSION: This is an uncommon disease. The most important diagnostic characteristic is coincidence of painful symptoms with menstruation. Patients undergoing cesarean section are at greatest risk: relative risk of 27.37 (P < 0.01. The surgical treatment of choice is excision of the endometrioma with a safety margin.

    The burn injury probably represents the largest stimulus for muscle protein catabolism. This state is characterized by an accelerated catabolism of the lean or skeletal mass that results in a clinical negative balance of nitrogen and muscle wasting. The determination of an appropriate value for protein intake is essential, since it is positively related to the nitrogen balance (NB) and accordingly several authors argue that a positive NB is the key parameter associated with nutritional improvement of a burn patient. Evaluation of the degree of protein catabolism by assessment of the Nitrogen Balance; Defining of nutritional support (protein needs) to implement in patients with burned surface area (BSA) = 10%. We prospectively evaluated the clinical files and scrutinized the clinical variables of interest. The NB was estimated according to three formulae. Each gram of nitrogen calculated by the NB was then converted into grams of protein, subtracted or added to protein intake (or administered enteric or parenterically) and divided by kg of reference Weight (kg Rweight), in an attempt to estimate the daily protein needs. The cohort consisted of 10 patients, 6 females, with average age of 58(23) years old, a mean of BSA of 21.4(8.4)%, ranging from a minimum of 10.0% and máximum of 35.0%. On average, patients were 58 (23) years old. The average number of days of hospitalization in the burn unit was 64.8(36.5) days. We observed significant differences between the 3 methods used for calculating the NB (p = 0.004), on average the NB was positive. When the formula A was used the average value of NB was higher. Regarding the attempt to estimate the needs of g prot/kg Rweight/day most of the values did not exceed, on average, 2.6 g Prot/kg Rweight/day and no significant differences between patients with a BSA% of 10-20% and with BSA% > 20% were found. Despite being able to estimate the protein catabolism through these formulas and verifying that most values were above zero

    2014-01-01

    Full Text Available Context: The established techniques that have been used to treat gynaecomastia are said to have relatively less patient satisfaction rate as they leave some visible scars or mild elevation over the nipple areola complex, resulting in aesthetically unsatisfactory results. Even the slightest elevation or smallest scar over nipple areola complex leave patients extremely self conscious and in a dilemma of having a second intervention to get rid of that blemish. Aims: The aim of the study is to achieve - A flat chest without adding a scar and with no chances of re-occurrence of the condition. This article suggests an innovative approach to address the problem. Materials and Methods: The author presents trans-nipple incision approach for the delivery of fibro-glandular tissue component following liposuction for maximum patient satisfaction. This method consists of a unique small criss-cross incision right on the nipple itself for retrieving any volume of tough fibro-glandular tissues. Between the duration of January 2012 to October 2013, 28 male patients of different ages were operated with this technique. Results: The surgery resulted in well-shaped, symmetric chest contour without any visible elevation or additional scars on nipple areola complex. No complications were noticed in any of the patients. Conclusions: The presented technique is proved to have a high patient satisfaction rate and to be promising method to achieve good aesthetic results in gynaecomastia surgery.

    We assessed the role of therapeutic delay time (TDT) in acute renal cortical scintigraphic lesion (ASL) and ultimate scar formation (USF) in children with first febrile UTI and whether it is affected by the presence of vesico-ureteral reflux (VUR). 230 children, 90 girls and 140 boys with first febrile UTI were included. Radiologic (USG, DMSA, and VCUG), clinical (age, gender, peak fever, therapeutic delay time) and laboratory (CBC with differential count, ANC (absolute neutrophil count), BUN, Creatinine, urine analysis, gram stain, culture, CRP and ESR) variables were analysed. DMSA was performed within 5 days and after six months. VCUG was performed after acute phase of UTI. The differences in TDT according to the presence of ASL, USF and VUR were assessed. And the correlation between ASL or USF with the duration of TDT was assessed. Of 230 patients enrolled, 142 patients had refluxing UTI and 88 patients had non-refluxing UTI. TDT was the risk factor associated with ASL and USF along with presence of VUR. TDT was longer in ASL positive group compared with the ASL negative group. Also USF group showed longer TDT compared with those without USF in both refluxing UTI and non refluxing UTI. The TDT was significantly shorter in USF group with the presence of VUR. Positive linear association was noted between prevalence of ASL and USF and duration of TDT. In conclusion, the impact of UTI on formation of USF may be enhanced by the presence of VUR with shorter duration of TDT.

    Objective: To discuss the feasibility and safety of uterine artery chemoembolization in treating cesarean section scar pregnancy. Methods: During the period of Jun. 2005-Jun. 2010, uterine artery chemoembolization was performed in 130 patients with cesarean section scar pregnancy in authors' hospital. Via bilateral uterine arteries 100-150 mg MTX and 80 000 u Gentamycin were infused separately, which was followed by the embolization of bilateral uterine arteries with Gelfoam. Of the total 130 patients,coexisted leiomyoma was found in 23 and embolization therapy with PVA microspheres was employed. Curettage of uterus was carried out within 24-72 hours after the procedure. Results: The success rate of bilateral uterine artery chemoembolization was 100%. The blood loss during curettage procedure was 12-110 ml (mean 28.5 ml). No serious complications occurred. Conclusion: The uterine artery chemoembolization is an effective and safe treatment for cesarean section scar pregnancy. This technique can greatly avoid unnecessary uterectomy and, thus, preserve the fertility of the female patients. (authors)

    This study sought to test the accuracy of strain measurements based on anatomo-electromechanical mapping (AEMM) measurements compared with magnetic resonance imaging (MRI) tagging, to evaluate the diagnostic value of AEMM-based strain measurements in the assessment of myocardial viability, and the additional value of AEMM over peak-to-peak local voltages. The in vivo identification of viable tissue, evaluation of mechanical contraction, and simultaneous left ventricular activation is currently achieved using multiple complementary techniques. In 33 patients, AEMM maps (NOGA XP, Biologic Delivery Systems, Division of Biosense Webster, a Johnson & Johnson Company, Irwindale, California) and MRI images (Siemens 3T, Siemens Healthcare, Erlangen, Germany) were obtained within 1 month. MRI tagging was used to determine circumferential strain (E cc ) and delayed enhancement to obtain local scar extent (%). Custom software was used to measure E cc and local area strain (LAS) from the motion field of the AEMM catheter tip. Intertechnique agreement for E cc was good (R 2  = 0.80), with nonsignificant bias (0.01 strain units) and narrow limits of agreement (-0.03 to 0.06). Scar segments showed lower absolute strain amplitudes compared with nonscar segments: E cc (median [first to third quartile]: nonscar -0.10 [-0.15 to -0.06] vs. scar -0.04 [-0.06 to -0.02]) and LAS (-0.20 [-0.27 to -0.14] vs. -0.09 [-0.14 to -0.06]). AEMM strains accurately discriminated between scar and nonscar segments, in particular LAS (area under the curve: 0.84, accuracy = 0.76), which was superior to peak-to-peak voltages (nonscar 9.5 [6.5 to 13.3] mV vs. scar 5.6 [3.4 to 8.3] mV; area under the curve: 0.75). Combination of LAS and peak-to-peak voltages resulted in 86% accuracy. An integrated AEMM approach can accurately determine local deformation and correlates with the scar extent. This approach has potential immediate application in the diagnosis, delivery of intracardiac therapies, and their

    Burns leave patients with long-term physical scarring. Children with scarring are required to face challenges of reintegration into their community, including acceptance of an altered appearance and acceptance by others. This can be difficult given society's preoccupation with physical appearance. Limited research exists investigating validity of cosmetic camouflage as a psychosocial intervention for children with scarring. This study investigated whether using cosmetic camouflage (Microskin™) had a positive impact on health-related quality of life, self-concept and psychopathology for children and adolescents (8-17 years) with burn scarring. A prospective multi-centre randomised controlled trial was conducted across Australian and New Zealand paediatric hospitals. 63 participants (49 females, mean age 12.7 ± 2.1 years) were enrolled. Data points were baseline (Time 1) and at 8 weeks (Time 2) using reliable and valid psychometric measures. Findings indicate there were significant improvements in socialisation, school and appearance scales on the Paediatric Quality of Life Inventory and psychopathology scores particularly peer problems decreased. However self-concept remained stable from baseline throughout intervention use. Cosmetic camouflage appears to have a positive impact on quality of life particularly socialisation. Cosmetic camouflage is a valid tool to assist children with scarring to actively participate socially within their communities. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    2011-01-01

    Objective: To evaluate uterine artery embolization in treating uterine scar pregnancy. Methods: During the period from November 2007 to February 2010, 11 patients with uterine scar pregnancy were encountered in authors' hospital. All the patients had a history of lower uterine segment cesarean section. Four patients had to receive an emergency uterine artery embolization due to acute massive vaginal bleeding. The other 7 patients received intravenous chemotherapy with MTX (0.4 mg/kg/day, every 5 days as a treatment course). Emergency uterine artery embolization had to be carried out in three patients as they developed acute massive vaginal bleeding (blood loss ≥ 100 ml/hour) during the course of chemotherapy, while subsequent uterine artery embolization was performed in the remaining 4 patients after they had completed two courses of treatment when their blood HCG showed no significant decrease. The clinical results were analyzed. Results: Remarkable decrease in serum HCG was seen in all 11 patients after interventional management. The vaginal bleeding in 7 patients was significantly reduced within half an hour after uterine artery embolization. The uterus together with intact fertility was successfully preserved in all 11 patients. Conclusion: For the treatment of uterine scar pregnancy complicated by massive vaginal bleeding (blood loss ≥ 500 ml/24 h) and/or abnormal elevation of serum HCG (blood β-HCG ≥ 20000 IU/L), ectopic pregnancy with the mass diameter ≥ 5 cm, uterine artery embolization treatment is very safe and effective. This technique can well preserve female patient's uterus and fertility ability. It is of value to employ this treatment in clinical practice. (authors)

    Scars resulting from deliberate self-harm (DSH) represent therapeutically challenging forms of scarring due to their highly variable patterns, with no official therapeutic guidelines available. In this pilot study, we aimed to evaluate the effectiveness and safety of a non-ablative fractional Er:glass 1565 nm laser, as a potential new, minimal-invasive approach for the improvement of DSH scars. Sixteen Caucasians suffering from mature DSH scars were included in this clinical study. Patients received a total of three treatments using a non-ablative fractional 1565 nm Er:glass laser every 4 weeks, employing two passes (300 μbeams/cm 2 , 40 mJ, onto the scar; 150 μbeams/cm 2 , 50 mJ, overall area). Measurements included questionnaires (DLQI, POSAS), digital photography, and objective three-dimensional analysis using PRIMOS and VECTRA software at baseline, 1 and 6 months after treatment. PRIMOS objective measurements showed highly significant changes in scar surface with a reduction of atrophic lesions by 27.5% at 6 months follow-up (FU), a decrease in scar height by 42.7% at 6 months FU, resulting in an overall diminished skin irregularity dropping from 678.3 μm at baseline to 441.6 μm throughout the course of the study (p = laser represents a promising and safe approach for the therapy of DSH scars. Although these scars will never fully resolve, their appearance can be significantly improved to a cosmetically and socially more acceptable appearance.

  15. Anterior abdominal Wall scar endometriosis: Case series and review of imaging modalities

    Full Text Available Implantation of endometriosis to pelvic and abdominal scar tissue is a very rare occurrence. Most commonly observed after cesarean sections due to implantation of uterine endometrial stem cells to outside tissues. Patients are often asymptomatic but may present with cyclic pain and mass. Imaging diagnosis is possible when classical implantation site near the scar tissue, clinical history and imaging findings are combined. In ultrasound imaging the lesion is often solid, mildly hypoechoic and often isoechoic to surrounding muscle. Presence of bleeding and fluid may cause the lesion to appear more heterogeneous. On computed tomography imaging the most pronounced finding is avid contrast enhancement of the lesion whereas in magnetic resonance imaging sensitivity to blood products.

  16. Renal scar formation after urinary tract infection in children

    Full Text Available Urinary tract infection (UTI is a common bacterial illness in children. Acute pyelonephritis in children may lead to renal scarring with the risk of later hypertension, preeclampsia during pregnancy, proteinuria, and renal insufficiency. Until now, vesicoureteral reflux (VUR has been considered the most important risk factor for post-UTI renal scar formation in children. VUR predisposes children with UTI to pyelonephritis, and both are associated with renal scarring. However, reflux nephropathy is not always acquired; rather, it reflects refluxassociated congenital dysplastic kidneys. The viewpoint that chronic kidney disease results from renal maldevelopment-associated VUR has led to questioning the utility of any regimen directed at identifying or treating VUR. Despite the recognition that underlying renal anomalies may be the cause of renal scarring that was previously attributed to infection, the prevention of renal scarring remains the goal of all therapies for childhood UTI. Therefore, children at high risk of renal scar formation after UTI should be treated and investigated until a large clinical study and basic research give us more information.

    Pressure garment therapy (PGT) is well accepted and commonly used by clinicians in the treatment of burns scars and grafts. The medium to high pressures (24-40 mmHg) in these garments can support scar minimisation, and evidence is well documented for this particular application. However, PGT specifically for burn donor sites, of which a sequela is also scarring, is not well documented. This study protocol investigates the impact of a low pressure (4-6 mmHg) interim garment on donor site healing and scarring. With a primary purpose of holding donor dressings in place, the application of the interim pressure garment (IPG) appears to have been twofold. IPGs for donor sites have involved inconsistent application with a focus on securing wound dressing rather than scar management. However, anecdotal and observational evidence suggests that IPGs also make a difference to some patient's scar outcomes for donor sites. This study protocol outlines a randomised controlled trial designed to test the effectiveness of this treatment on reducing scarring to burn donor sites. This study is a single-centre, single (assessor)-blinded, randomised control trial in patients with burns donor sites to their thighs. Patients will be randomly allocated to a control group (with no compression to donor sites) or to an experimental group (with compression to donor sites) as the comparative treatment. Groups will be compared at baseline regarding the important prognostic indicators: donor site location, depth, size, age, and time since graft (5 days). The IPG treatment will be administered post-operatively (on day 5). Follow-up assessments and garment replacement will be undertaken fortnightly for a period of 2 months. This study focuses on a unique area of burns scar management using a low-pressure tubular support garment for the reduction of donor site scars. Such therapy specifically for donor scar management is poorly represented in the literature. This study was designed to test a

    Full Text Available Burns account for a significant proportion of injuries, and of these the face, neck, and anterior torso are commonly affected. Burn scars remain a lasting reminder of the insult both for the patient and the outside world. There is little doubt that the change in appearance and the limitation imposed by a burn scar contribute to negative body image. Treatment of hypertrophic scars in the neck has been quite challenging if there is no intact tissue for local flaps. So application of full-thickness skin grafts could be of great value. We applied full-thickness grafts obtained from lower abdominal skin for treatment of severe neck contractures in four patients when other treatment modalities such as local flaps could not be used. Full-thickness skin graft of the neck is a safe and reliable treatment option with fairly good functional and aesthetic results. It has little donor site morbidity in spite of providing a large surface area of full-thickness skin.

    To retrospectively analyze the clinical data of 71 patients with exogenous cesarean scar pregnancy (CSP) treated in our hospital in the past 2 years, to compare the outcomes of exogenous CSP treated with different methods, and to evaluate the safety and feasibility of laparoscopic resection of exogenous CSP. Comparative observational study. Tertiary medical centers. 71 women with exogenous cesarean scar pregnancy. Hysteroscopic resection of CSP, and laparoscopic resection of CSP. Operation time, intraoperative blood loss, postoperative drainage of the uterine cavity, postoperative days in hospital, time for β-human chorionic gonadotropin (β-hCG) to return to normal levels, absorption time of the mass. For the laparoscopic group, the time for serum β-hCG to return normal levels and the postoperative drainage of the uterine cavity were significantly lower than in the patients who had undergone hysteroscopic resection. We found no statistically significant difference in the intraoperative blood loss and postoperative days in hospital between the two groups, but the operation time was longer in laparoscopic group. Laparoscopic surgery for a cesarean scar pregnancy has the advantages of a high success rate, fewer complications, and a shorter time for β-hCG levels to normalize. This procedure is especially suitable for the treatment of exogenous CSP. Copyright © 2014. Published by Elsevier Inc.

  20. Advanced skin, scar and wound care centre for children: A new era of care

    Full Text Available Advanced wound care centres are now a well established response to the growing epidemic of chronic wounds in the adult population. Is the concept transferable to children? Whilst there is not the same prevalence of chronic wounds in children there are conditions affecting the integumentary system that do have a profound effect on the quality of life of both children and their families. We have identified conditions involving the skin, scars and wounds which contribute to a critical number of potential patients that can justify the setting up of an advanced skin, scar and wound care centre for children. The management of conditions such as giant naevi, extensive scarring and epidermolysis bullosa challenge medical professionals and lead to new and novel treatments to be developed. The variation between and within such conditions calls for a customizing of individual patient care that involves a close relationship between research scientists and clinicians. This is translational medicine of its best and we predict that this is the future of wound care particularly and specifically in children.

    To evaluate the contrast-enhanced MR findings of lesions associated with a radial scar and to compare the MR findings with the histopathology results. From Mar. 2001 to Sep. 2005, 8 patients with a surgically proven radial scar who had undergone MRI, mammography, and ultrasonography were enrolled in this study. The morphological findings and dynamic enhancement pattern of the time-intensity curve were retrospectively reviewed using noncontrast and contrast-enhanced MRI. Mammography and ultrasonography were also analyzed according to the BI-RADS category and correlated with the histopathological diagnosis. The age of the patients ranged from 42 to 53 years (mean, 47 years). Five patients presented with a left breast lesion and the others presented with a right breast lesion. The histopathological diagnosis associated with the radial scar were fibrocystic changes (n = 1) adenosis (n = 2), atypical ductal hyperplasia (n = 2), lobular carcinoma in situ (n = 1), ductal carcinoma in situ (n = 1), and invasive ductal carcinoma (n = 1). In all patients, architectural distortion without microcalcification was observed with mammography. Irregular shaped hypoechoic lesions with an indistinct, spiculated, or angular margin was observed in all patients with ultrasonography. Posterior shadowing was observed in 4 cases. MR enhancement revealed two cases with foci enhancement (adenosis and fibrocystic change), five cases with non-mass-like focal enhancement (fibrocystic change, atypical ductal hyperplasia, lobular carcinoma in situ, ductal carcinoma in situ, invasive ductal carcinoma), and one irregular homogeneous mass enhancement (atypical ducal hyperplasia). The time-signal intensity curves are as follows: persistent type (n = 2), adenosis, and fibrocystic changes, respectively; plateu type (n = 4) one adenosis, two atypical ductal hyperplasia, and one ductal carcinoma in situ; and washout type (n = 2), lobular carcinoma in situ, and invasive ductal carcinoma, respectively

    Research suggests that the resectoscopic management of abnormal uterine bleeding (AUB) following cesarean section (CS) is safe and effective. There is, however, a lack of complementary data from routine clinical practice. We aimed to evaluate the efficacy of resectoscopic remodeling of the CS scar in the management of post CS AUB (pCSAUB). The case notes of 57 women with pCSAUB who had undergone a resectoscopic remodeling procedure were reviewed retrospectively. Primary outcome measures were the duration of preoperative and postoperative menstruation, and postoperative menstrual change. Secondary outcome measures were the impact of patient-dependent variables on the success of the resectoscopic remodeling procedure. The CS scar was located using transvaginal ultrasonography and hysteroscopy. The remodeling procedure was performed with a hysteroscopic resectoscope, and commenced with resection of the fibromuscular scar. This started at the roof of the scar pouch and progressed towards the external os. It then continued along a line parallel to the axis of the cervical canal. The exposed dilated blood vessels and endometrial-like tissue in the roof of the remaining pouch were electrocauterized with a roller-ball electrode. The mean operating time was 30.2 ± 6.6 min. There was a significant difference in the mean duration of preoperative and postoperative menstruation (12.9 ± 2.9 days and 9.4 ± 4.1 days, respectively; p uterine remodeling is an appropriate therapy in patients with pCSAUB and an anteflexed uterus.

    Full Text Available Background/Aim. The heart has traditionally been considered as a static organ without capacity of regeneration after trauma. Currently, the more and more often asked question is whether the heart has any intrinsic capacities to regenerate myocytes after myocardial infarction. The aim of this study was to present the existence of the preserved muscle fibers in the myocardial scar following myocardial infarction as well as the presence of numerous cells of various size and form that differently reacted to the used immunohistochemical antibodies. Methods. Histological, histochemical and immunohistochemical analyses of myocardial sections taken from 177 patients who had died of acute myocardial infarction and had the myocardial scar following myocardial infarction, were carried out. More sections taken both from the site of acute infarction and scar were examined by the following methods: hematoxylin-eosin (HE, periodic acid schiff (PAS, PAS-diastasis, Masson trichrom, Malory, van Gieson, vimentin, desmin, myosin, myoglobin, alpha actin, smoth muscle actin (SMA, p53, leukocyte common antigen (LCA, proliferating cell nuclear antigen (PCNA, Ki-67, actin HHF35, CD34, CD31, CD45, CD45Ro, CD8, CD20. Results. In all sections taken from the scar region, larger or smaller islets of the preserved muscle fibers with the signs of hypertrophy were found. In the scar, a large number of cells of various size and form: spindle, oval, elongated with abundant cytoplasm, small with one nucleus and cells with scanty cytoplasm, were found. The present cells differently reacted to histochemical and immunohistochemical methods. Large oval cells showed negative reaction to lymphocytic and leukocytic markers, and positive to alpha actin, actin HHF35, Ki-67, myosin, myoglobin and desmin. Elongated cells were also positive to those markers. Small mononuclear cells showed positive reaction to lymphocytic markers. Endothelial and smooth muscle cells in the blood vessel walls

    2008-01-01

    Imaging of children with a clinical diagnosis of pyelonephritis is performed to characterize the extent of the infection, to identify associated renal injury and to uncover risk factors for future infections and renal damage. Although there is general agreement regarding the need for parenchymal imaging and the need to exclude processes that are either functionally or anatomically obstructive, there is controversy regarding the need for routine cystography, especially when parenchymal involvement has not been documented. A protocol that limits the use of cystography for evaluation of urinary tract infections must assume that the diagnosis of reflux is at least of variable clinical significance. It is now clear that vesicoureteral reflux and reflux nephropathy represent a diverse population that includes both congenital and acquired processes. MR imaging will improve our understanding of vesicoureteral reflux, pyelonephritis and renal scarring and might help us to identify and manage those patients most at risk for recurrent infections and renal injury. To recognize the potential contributions of this newer imaging technique it is helpful to look at our understanding of the pathophysiology of pyelonephritis, reflux and reflux nephropathy. (orig.)

    Full Text Available Urethral stricture disease is increasingly common occurring in about 1% of males over the age of 55. The stricture tissue is rich in myofibroblasts and multi-nucleated giant cells which are thought to be related to stricture formation and collagen synthesis. An increase in collagen is associated with the loss of the normal vasculature of the normal urethra. The actual incidence differs based on worldwide populations, geography, and income. The stricture aetiology, location, length and patient's age and comorbidity are important in deciding the course of treatment. In this review we aim to summarise the existing knowledge of the aetiology of urethral strictures, review current treatment regimens, and present the challenges of using tissue-engineered buccal mucosa (TEBM to repair scarring of the urethra. In asking this question we are also mindful that recurrent fibrosis occurs in other tissues—how can we learn from these other pathologies?

    It has become clear that obesity is associated with a variety of infectious diseases, including urinary tract infection (UTI) and renal scarring. The aim of this study was to evaluate the association between obesity and the degree of febrile UTI (fUTI) and renal scarring in children with vesicoureteral reflux (VUR), and to stratify the results into obesity subcategories. A total of 186 patients were diagnosed with VUR between January 2002 and December 2008. This study retrospectively reviewed the medical records of 72 children with primary VUR who had recurrent fUTI (more than twice). Overweight or obese status of the patients aged children, body mass index (BMI) percentile-for-age was used. They were divided into three groups as follows; standard (obese (≥95%). The following clinical variables were compared: age at diagnosis of primary VUR (months), sex, VUR grade, hydronephrosis grade, presence of renal scarring, surgical treatment, and degree of inflammation during fUTI. In the overweight and obese groups, VUR was diagnosed at a young age (P = 0.05), the degree of renal scarring was more severe (P = 0.006), and serum white blood cell count, C-reactive protein, and erythrocyte sedimentation rate (ESR) levels were significantly higher (P children (35%). Cortical defects occurred more frequently in children with obesity, and they were associated with a higher grade of reflux and serum ESR levels (P = 0.007, P = 0.042, and P = 0.021, respectively). Among these risk factors, high-grade VUR (OR = 9.93, 95% CI = 1.13-86.71), and being overweight and obese (OR = 5.26, 95% CI = 1.75-15.82) were associated with increased renal scarring. However, ESR was not associated with renal scarring (OR = 1.01, 95% CI = 0.95-1.07). The relationships between obesity and UTI are controversial. Some studies have shown positive results; however, other studies have shown opposite results. The main limitations of this study were the retrospective data collection

Gynecomastia was seen on the left side of the chest in 13 patients and on the right side in 10 patients. There were no complications. The specimens did not reveal any malignant causes. Conclusion: Although most cases gynecomastia are idiopathic and bilateral, there are instances that require special at- tention and should be given unilateral status. Detailed evaluation including physical examination, history of drug use and concomitant medical disorders should be considered. [Arch Clin Exp Surg 2016; 5(4.000: 206-210

    2013-05-01

    We report a 33-year-old female with cutaneous involvement by Churg-Strauss syndrome confined to surgical scars that were obtained 13 years before. She presented to the emergency department with 2-day history of fever, night sweats, right-sided weakness, hoarseness and worsening asthma symptoms. She was found to have an eosinophilia and two sub-5-mm pulmonary nodules. The patient also reported that the scars on her right thumb, inner wrist and back had been swollen, red and painful for 2 days. Examination revealed tender, erythematous, well-healed edematous scars studded with small skin colored papules. She had no clinical findings that were classic for cutaneous vasculitis. A skin biopsy of a scar revealed perivascular and palisading granulomatous inflammation consisting of histiocytes and neutrophils with leukocytoclasia. Focal vascular injury was identified. Scattered tissue eosinophils were seen. Special stains were negative for infection. Thereafter, she was started on intravenous steroids, at which point the fever, pulmonary and cutaneous symptoms subsided. Although scar sarcoidosis is a well-described phenomenon, granulomatous inflammation and vasculitis seen in Churg-Strauss syndrome exclusively manifesting in well-healed surgical scars highlights the unique features seen in this case and draws attention to the concept of locus minoris resistentiae. This case also highlights how a skin biopsy in the setting of suspected systemic vasculitis can confirm the presence of vasculitis and/or granulomatous inflammation and obviate the need for more invasive, higher risk procedures such as lung biopsy.

    Intrathecal infusion has been widely used to directly deliver drugs or neurotrophins to a lesion site following spinal cord injury. Evidence shows that intrathecal infusion is efficient for 7 days but is markedly reduced after 14 days, due to time dependent occlusion. In addition, extensive fibrotic scarring is commonly observed with intrathecal infusion. These anomalies need to be clearly elucidated in histology. In the present study, all adult Long-Evans rats received a 25 mm contusion injury on spinal cord T10 produced using the NYU impactor device. Immediately after injury, catheter tubing with an outer diameter of 0.38 mm was inserted through a small dural opening at L3 into the subdural space with the tubing tip positioned near the injury site. The tubing was connected to an Alzet mini pump, which was filled with saline solution and was placed subcutaneously. Injured rats without tubing served as control. Rats were behaviorally tested for 6 weeks using the BBB locomotor rating scale and histologically assessed for tissue scarring. Six weeks later, we found that the intrathecal tubing caused extensive scarring and inflammation, related to neutrophils, macrophages and plasma cells. The tubing's tip was occluded by scar tissue and inflammatory cells. The scar tissue surrounding the tubing consists of 20-70 layers of fibroblasts and densely compacted collagen fibers, seriously compressing and damaging the cord tissue. BBB scores of rats with intrathecal tubing were significantly lower than control rats (p<0.01) from 2 weeks after injury, implying serious impairment of functional recovery caused by the scarring.

    Objective: Proteins of the matrix metalloproteinases family play a vital role in extracellular matrix maintenance and basic physiological processes in tissue homeostasis. The function and activities of matrix metalloproteinases in response to compression therapies have yet to be defined. Here, a swine model of hypertrophic scar was used to profile the transcription of all known 26 matrix metalloproteinases in scars treated with a precise compression dose. Methods: Full-thickness excisional wounds were created. Wounds underwent healing and scar formation. A subset of scars underwent 2 weeks of compression therapy. Biopsy specimens were preserved, and microarrays, reverse transcription-polymerase chain reaction, Western blotting, and immunohistochemistry were performed to characterize the transcription and expression of various matrix metalloproteinase family members. Results: Microarray results showed that 13 of the known 26 matrix metalloproteinases were differentially transcribed in wounds relative to the preinjury skin. The predominant upregulation of these matrix metalloproteinases during early wound-healing stages declined gradually in later stages of wound healing. The use of compression therapy reduced this decline in 10 of the 13 differentially regulated matrix metalloproteinases. Further investigation of MMP7 using reverse transcription-polymerase chain reaction confirmed the effect of compression on transcript levels. Assessment of MMP7 at the protein level using Western blotting and immunohistochemistry was concordant. Conclusions: In a swine model of hypertrophic scar, the application of compression to hypertrophic scar attenuated a trend of decreasing levels of matrix metalloproteinases during the process of hypertrophic wound healing, including MMP7, whose enzyme regulation was confirmed at the protein level.

    Burns can have both physical and psychological effects on individuals. Pressure garments and silicone gels are used to improve the aesthetic appearance and functions of the skin, but these treatments have been associated with various physical, emotional, sexual and social difficulties. Interpretative phenomenological analysis (IPA) was used to explore participants' experiences of scar management. IPA examines individual experiences before comparing results across cases, and is suited to capture the different ways in which individuals experience a phenomena as well as cautiously looking at patterns across cases. Eight burn patients who had experienced scar management, including pressure garments, were interviewed. Two superordinate themes were identified: Assimilation of Pressure Garment Identity, and Psychosocial Functions of the Pressure Garments. The findings offered insight into the positive and negative experiences of scar management, describing the diverse personal and social functions of the pressure garments and how they became integrated into participants' identities. By understanding the individual nature of these experiences, healthcare professionals can enhance support around these issues and potentially aid adherence to treatment. Further research with different demographic groups as well as for other burn treatments would be useful to develop and contextualise these findings. Copyright © 2016 Elsevier Ltd and ISBI.

    Keloids and hypertrophic scars occur anywhere from 30 to 90% of patients, and are characterized by pathologically excessive dermal fibrosis and aberrant wound healing. Both entities have different clinical and histochemical characteristics, and unfortunately still represent a great challenge for clinicians due to lack of efficacious treatments. Current advances in molecular biology and genetics reveal new preventive and therapeutical options which represent a hope to manage this highly prevalent, chronic and disabling problem, with long-term beneficial outcomes and improvement of quality of life. While we wait for these translational clinical products to be marketed, however, it is imperative to know the basics of the currently existing wide array of strategies to deal with excessive scars: from the classical corticotherapy, to the most recent botulinum toxin and lasers. The main aim of this review paper is to offer a useful up-to-date guideline to prevent and treat keloids and hypertrophic scars. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Background Ablative fractional carbon dioxide (CO2) laser treatments have gained popularity due to their efficacy, shortened downtime, and decreased potential for scarring in comparison to traditional ablative CO2 resurfacing. To date, scarring with fractional CO2 lasers has not been reported. Objective Five patients treated with the same fractional CO2 laser technology for photodamage of the neck were referred to our practices 1–3 months after treatment. Each patient developed scarring. Of the five cases, two are discussed in detail. The first was treated under general anesthesia on the face and anterior neck at a pulse energy of 30 mJ (859 μm depth) with 25% coverage. Eleven days after treatment, three non-healing areas along the horizontal skin folds of the anterior neck were noted. At 2 weeks after CO2 ablative fractional resurfacing, these areas had become thickened. These raised areas were treated with a non-ablative fractionated 1,550 nm laser to modify the wound healing milieu. One week later, distinct firm pale papules in linear arrays with mild hypopigmentation had developed along involved neck skin folds. Skin biopsy was performed. For the second patient, the neck was treated at a pulse energy of 20 mJ (630 μm depth) with 30% coverage of the exposed skin, with a total treatment energy of 5.0 kJ. Minimal crusting was noted on the neck throughout the initial healing phase of 2 weeks. She then experienced tightness on her neck. Approximately 3 weeks after treatment, she developed multiple vertical and horizontal hypertrophic scars (HS). Results Histopathology for the first case confirmed the presence of a hypertrophic scar. The papules in this case completely resolved with mild residual hypopigmentation after treatment with topical corticosteroids. HS failed to resolve in the second case to date after 1 month. Conclusion As with traditional ablative CO2 laser resurfacing, HS is a potential complication of ablative fractional CO2 laser resurfacing

  18. Descendants of Hardship: Prevalence, Drivers and Scarring Effects of Social Exclusion in Childhood

    Full Text Available The social exclusion of children is problematic for two reasons. Young people typically inherit their marginal position from their family, and therefore cannot be held responsible for their hardship themselves; and social exclusion in childhood may affect their wellbeing and subsequent development, possibly leading to a “scarring effect” in later life. In this contribution we develop an instrument for measuring social exclusion among children. Social exclusion is regarded as a theoretical construct with four sub-dimensions: material deprivation, limited social participation, inadequate access to social rights, and a lack of normative integration. First we analyse data from a survey of 2,200 Dutch children, which contains a large set of social exclusion items. We applied nonlinear principal components analysis in order to construct a multidimensional scale. Measured in this way, the prevalence of social exclusion among children is 4.5%. Boys and children living in large families are more likely to experience social exclusion than girls and children with few siblings. The parental level of education and dependency on social security benefits are also important driving factors of childhood social exclusion. Subsequently we investigate the scarring effect. Longitudinal administrative income and household data covering 25 years were combined with a new survey of just under 1,000 Dutch adults, a third of whom were poor as a child. The survey assessed their past and current degree of social exclusion, and their health and psychosocial development, educational career, past family circumstances, etc. In an absolute sense scarring turns out to have been limited during this period: a very large majority of those who were poor or excluded as a child are above the threshold values in adult life. However, the “descendants of hardship” are still more likely to be socially excluded as adults than people who grew up in more favourable conditions. A

    Ablative carbon dioxide (CO(2) ) fractional resurfacing is a promising therapeutic intervention for the treatment of acne scars, although this technique is associated with prolonged surgical site erythema and edema, which may affect the daily lives of patients. Autologous platelet-rich plasma (PRP) is known to enhance wound healing and has applications in many areas of medicine. To evaluate the synergistic effects of autologous PRP with CO(2) fractional resurfacing for acne scars. A split-face trial was conducted in 14 Korean participants with acne scars. All participants received one session of ablative CO(2) fractional resurfacing. Immediately after resurfacing, facial halves were randomly assigned to receive treatment with autologous PRP injections on one side (experimental side) and normal saline injections on the other side (control side). The participants were monitored for degree of recovery and resurfacing-associated adverse events, including prolonged erythema, edema, and other effects on days 0, 2, 4, 6, 8, 15, and 30. The intensity of erythema was objectively measured using a chromometer at the same time intervals. After one additional treatment session using the same protocol, two independent dermatologists evaluated clinical improvement using a quartile grading scale. All participants completed the study. Erythema on the experimental side improved faster than on the control side and was significantly less at day 4 (p=.01). This difference was confirmed using a chromometer (p=.049). Total duration of erythema was an average of 10.4±2.7 days on the control side and 8.6±2.0 days on the experimental side (p=.047). Edema also improved faster on the experimental side than on the control side. The total duration of edema was an average of 7.1±1.5 days on the control side and 6.1±1.1 days on the experimental side (p=.04). Participants were also assessed for duration of post-treatment crusting, with a mean of 6.8±1.0 days on the control side and 5.9±1

    2016-10-01

    To determine a measurement standard of irregular scar area by comparing the advantages and disadvantages of different measurement methods in measuring same irregular scar area. Irregular scar area was scanned by digital scanning and measured by coordinate reading method, AutoCAD pixel method, Photoshop lasso pixel method, Photoshop magic bar filled pixel method and Foxit PDF reading software, and some aspects of these methods such as measurement time, repeatability, whether could be recorded and whether could be traced were compared and analyzed. There was no significant difference in the scar areas by the measurement methods above. However, there was statistical difference in the measurement time and repeatability by one or multi performers and only Foxit PDF reading software could be traced back. The methods above can be used for measuring scar area, but each one has its advantages and disadvantages. It is necessary to develop new measurement software for forensic identification.

    We examine the spatial field of orientations of slender fibers that are advected by a two-dimensional fluid flow. The orientation field of these passive directors are important in a wide range of industrial and geophysical flows. We introduce emergent scar lines as the dominant coherent structures in the orientation field of passive directors in chaotic flows. Previous work has identified the existence of scar lines where the orientation rotates by π over short distances, but the lines that were identified disappeared as time progressed. As a result, earlier work focused on topological singularities in the orientation field, which we find to play a negligible role at long times. We use the standard map as a simple time-periodic two-dimensional flow that produces Lagrangian chaos. This class of flows produces persistent patterns in passive scalar advection and we find that a different kind of persistent pattern develops in the passive director orientation field. We identify the mechanism by which emergent scar lines grow to dominate these patterns at long times in complex flows. Emergent scar lines form where the recent stretching of the fluid element is perpendicular to earlier stretching. Thus these scar lines can be labeled by their age, defined as the time since their stretching reached a maximum.

  3. Understanding the NG2 glial scar after spinal cord injury

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available NG2 cells, also known as oligodendrocyte progenitor cells, are located throughout the central nervous system and serve as a pool of progenitors to differentiate into oligodendrocytes. In response to spinal cord injury, NG2 cells increase their proliferation and differentiation into remyelinating oligodendrocytes. While astrocytes are typically associated with being the major cell type in the glial scar, many NG2 cells also accumulate within the glial scar but their function remains poorly understood. Similar to astrocytes, these cells hypertrophy, upregulate expression of chondroitin sulfate proteoglycans, inhibit axon regeneration, contribute to the glial-fibrotic scar border, and some even differentiate into astrocytes. Whether NG2 cells also have a role in other astrocyte functions, such as preventing the spread of infiltrating leukocytes and expression of inflammatory cytokines, is not yet known. Thus, NG2 cells are not only important for remyelination after spinal cord injury, but are also a major component of the glial scar with functions that overlap with astrocytes in this region. In this review, we describe the signaling pathways important for the proliferation and differentiation of NG2 cells, as well as the role of NG2 cells in scar formation and tissue repair.

    Full Text Available Hypertension affects about 65 million individuals in the United States. In adult patients, primary aldosteronism and renovascular causes are described as most prevalent. Vesicoureteral reflux as a cause of hypertension, while commonly described in pediatric populations, is less prevalent in the adult population especially in the absence of proteinuria. We present the case of a 31-year-old female presenting with early onset hypertension. Workup for renovascular hypertension was unrevealing. She was found to have right-sided vesicoureteral reflux with a unilateral scarred kidney. Patient underwent a nephrectomy with marked improvement in blood pressure control.

  5. Techniques for creating inconspicuous face-lift scars: avoiding visible incisions and loss of temporal hair.

    2003-01-01

    Patients seeking rhytidectomy desire an improved neckline, jawline, and midface, but rarely at the price of signs that betray a face-lift, namely, visible incisions. We describe our face-lift incisional planning and the rationale behind specific surgical maneuvers for preventing unwanted sequelae. The telltale signs of poorly placed incisions include temporal hair loss, conspicuous scars, an unnatural appearance to the tragus, and a posterior hairline distorsion. Special considerations are given to the male patient and to the salvage of readily visible incision lines from previous surgery.

    The non-invasive diagnostic possibilities of MR have resulted in better diagnosis of degenerative spinal diseases. Twenty-one patients with failed back surgery syndrome (postdiscectomy syndrome) were studied to evaluate the possibility of 1-Tesla magnetic resonance (MR) imaging with gadolinium diethylene triamine pentaacetic acid (Gd-DTPA) in differentiating post operative scar tissue from recurrent disc herniation. The enhanced MR studies correctly depicted the character of abnormal epidural tissue in all patients. We conclude that MR with Gd-DTPA might be the method of choice to differentiate reliably postoperative epidural fibrosis from recurrent disc prolapse. (orig.) [de

    2015-01-01

    To argue that if all nurses were to adopt the primary survey approach (assessment of airway, breathing, circulation and disability) as the first element of patient assessment, they would be more focused on active detection of clinical deterioration rather than passive collection of patient data. Nurses are the professional group that carry the highest level of responsibility for patient assessment, accurate data collection and interpretation. The timely recognition of, and response to deteriorating patients, is dependent on the measurement and interpretation of pertinent physiological data by nurses. Discursive paper. Traditionally taught and commonly used approaches to patient assessment such as 'vital signs' and 'body systems' are not evidence-based nor framed in patient safety. The primary survey approach as the first element in patient assessment has three major advantages: (1) data are collected according to clinical importance; (2) data are collected using the same framework as most organisation's rapid response system activation criteria; and (3) the primary survey acts as a patient safety checklist, thereby decreasing the risk of failure to recognise, and therefore respond to, deteriorating patients. The vital signs and body systems approaches to patient assessment have significant limitations in identifying clinical deterioration. The primary survey approach provides nurses with a consistent, evidence-based and sequenced approach to patient assessment in every clinical setting. All nurses should use a primary survey approach as the first element of patient assessment in every patient encounter as a patient safety strategy. © 2014 John Wiley & Sons Ltd.

    To illustrate the patient safety culture in Oman as gleaned via 12 indices of patient safety culture derived from the Hospital Survey on Patient Safety Culture (HSPSC) and to compare the average positive response rates in patient safety culture between Oman and the USA, Taiwan, and Lebanon. This was a cross-sectional research study employed to gauge the performance of HSPSC safety indices among health workers representing five secondary and tertiary care hospitals in the northern region of Oman. The participants (n=398) represented different professional designations of hospital staff. Analyses were performed using univariate statistics. The overall average positive response rate for the 12 patient safety culture dimensions of the HSPSC survey in Oman was 58%. The indices from HSPSC that were endorsed the highest included 'organizational learning and continuous improvement' while conversely, 'non-punitive response to errors' was ranked the least. There were no significant differences in average positive response rates between Oman and the United States (58% vs. 61%; p=0.666), Taiwan (58% vs. 64%; p=0.386), and Lebanon (58% vs. 61%; p=0.666). This study provides the first empirical study on patient safety culture in Oman which is similar to those rates reported elsewhere. It highlights the specific strengths and weaknesses which may stem from the specific milieu prevailing in Oman.

    Post-infarct ventricular tachycardia is associated with channels of surviving myocardium within scar characterized by fractionated and low-amplitude signals usually occurring late during sinus rhythm. Conventional automated algorithms for 3-dimensional electro-anatomic mapping cannot differentiate the delayed local signal of conduction within the scar from the initial far-field signal generated by surrounding healthy tissue. Ripple mapping displays every deflection of an electrogram, thereby providing fully informative activation sequences. We prospectively used CARTO-based ripple maps to identify conducting channels as a target for ablation. High-density bipolar left ventricular endocardial electrograms were collected using CARTO3v4 in sinus rhythm or ventricular pacing and reviewed for ripple mapping conducting channel identification. Fifteen consecutive patients (median age 68 years, left ventricular ejection fraction 30%) were studied (6 month preprocedural implantable cardioverter defibrillator therapies: median 19 ATP events [Q1-Q3=4-93] and 1 shock [Q1-Q3=0-3]). Scar (ripple mapping conducting channels were seen within each scar (length 60 mm; initial component 0.44 mV; delayed component 0.20 mV; conduction 55 cm/s). Ablation was performed along all identified ripple mapping conducting channels (median 18 lesions) and any presumed interconnected late-activating sites (median 6 lesions; Q1-Q3=2-12). The diastolic isthmus in ventricular tachycardia was mapped in 3 patients and colocated within the ripple mapping conducting channels identified. Ventricular tachycardia was noninducible in 85% of patients post ablation, and 71% remain free of ventricular tachycardia recurrence at 6-month median follow-up. Ripple mapping can be used to identify conduction channels within scar to guide functional substrate ablation. © 2016 American Heart Association, Inc.

    To evaluate the inter-study, inter-reader and intra-reader reproducibility of cardiac cine and scar imaging in rats using a clinical 3.0 Tesla magnetic resonance (MR) system. Thirty-three adult rats (Sprague–Dawley) were imaged 24 hours after surgical occlusion of the left anterior descending coronary artery using a 3.0 Tesla clinical MR scanner (Philips Healthcare, Best, The Netherlands) equipped with a dedicated 70 mm solenoid receive-only coil. Left-ventricular (LV) volumes, mass, ejection fraction and amount of myocardial scar tissue were measured. Intra-and inter-observer reproducibility was assessed in all animals. In addition, repeat MR exams were performed in 6 randomly chosen rats within 24 hours to assess inter-study reproducibility. The MR imaging protocol was successfully completed in 32 (97%) animals. Bland-Altman analysis demonstrated high intra-reader reproducibility (mean bias%: LV end-diastolic volume (LVEDV), -1.7%; LV end-systolic volume (LVESV), -2.2%; LV ejection fraction (LVEF), 1.0%; LV mass, -2.7%; and scar mass, -1.2%) and high inter-reader reproducibility (mean bias%: LVEDV, 3.3%; LVESV, 6.2%; LVEF, -4.8%; LV mass, -1.9%; and scar mass, -1.8%). In addition, a high inter-study reproducibility was found (mean bias%: LVEDV, 0.1%; LVESV, -1.8%; LVEF, 1.0%; LV mass, -4.6%; and scar mass, -6.2%). Cardiac MR imaging of rats yielded highly reproducible measurements of cardiac volumes/function and myocardial infarct size on a clinical 3.0 Tesla MR scanner system. Consequently, more widely available high field clinical MR scanners can be employed for small animal imaging of the heart e.g. when aiming at serial assessments during therapeutic intervention studies

    2015-02-01

    Limited functional health literacy is recognized as an important contributor to health disparities in the United States. As internet access becomes more universal, there is increasing concern about whether patients with poor or marginal literacy can access understandable healthcare information. As such, the National Institutes of Health and American Medical Association recommend that patient information be written at a sixth grade level. This study identifies the most popular online resources for patient information about abdominoplasty and evaluates their readability in the context of average American literacy. The two largest internet search engines were queried for "tummy tuck surgery" to simulate a patient search in lay terms. The ten most popular sites common to both search engines were identified, and all relevant articles from the main sites were downloaded. Sponsored results were excluded. Readability analysis of the articles was performed using ten established tests. Online information about abdominoplasty from the ten most popular publically available websites had an overall average readability of 12th grade. Mean reading grade level scores among tests were: Coleman-Liau 11.9, Flesch-Kincaid 11.4, FORCAST 11.1, Fry 13, Gunning Fog 13.5, New Dale-Chall 11.8, New Fog Count 9.9, Raygor Estimate 12, and SMOG 13.4; Flesch Reading Ease index score was 46. Online patient resources about abdominoplasty are uniformly above the recommended target readability level and are likely too difficult for many patients to understand. A range of readability identified among websites could allow surgeons to guide patients to more appropriate resources for their literacy skills.

    Preload assessment and optimization is the basic hemodynamic intervention in critically ill. Beside clinical assessment, non-invasive or invasive assessment by measurement of various pressure or volume hemodynamic variables, are helpful for estimation of preload and fluid responsiveness. The use of dynamic variables is useful in particular subgroup of critically ill patients. In patients with inadequate preload, fluid responsiveness and inadequate flow, treatment with crystalloids or colloids is mandatory. When rapid hemodynamic response is necessary colloids are preferred.

    No intraoperative imaging techniques exist for detecting tumor nodules or tumor scar tissues in patients treated with upfront or interval cytoreductive surgery (CS) after neoadjuvant chemotherapy (NAC). The aims of this study were to evaluate the role of indocyanine green (ICG) fluorescence imaging (FI) for the detection of peritoneal metastases (PM) and evaluate whether it can be used to detect remnant tumor cells in scar tissue. Patients with PM from ovarian cancer admitted for CS were included. ICG, at 0.25 mg per kg of patient weight, was injected intraoperatively after explorative laparotomy before CS. A total of 108 peritoneal lesions, including 25 scars, were imaged in 20 patients. Seventy-three were malignant (67.6%) and 35 benign (32.4%). The mean Tumor to Background Ratio (ex vivo) was 1.8 (SD 1.3) in malignant and 1.0 (SD 0.79) in benign nodules (P = 0.007). Of 25 post-NAC scars, the mean Tumor to Background Ratio (TBR) (in vivo) was 2.06 (SD 1.15) in malignant and 1.21 (SD 0.50) in benign nodules (P = 0.26). The positive predictive value of ICG-FI to detect tumor cells in scars was 57.1%. ICG-FI is accurate to demonstrate PM in ovarian cancer but unable to discriminate between benign and malignant post-NAC. © 2017 Wiley Periodicals, Inc.

    2015-02-01

    Jaundice in the hospitalized patient is not an uncommon consultation for the general gastroenterologist. It is essential to explore the underlying cause of jaundice because management is largely aimed at addressing these causes rather than the jaundice itself. Although the diagnostic evaluation for jaundice can be broad, clinical judgment must be used to prioritize between various laboratory tests and imaging studies. Most importantly, clinicians must understand which conditions are emergent and/or require evaluation for liver transplantation. Further studies need to be performed to better understand the outcomes of hospitalized patients who develop jaundice. Copyright © 2015 Elsevier Inc. All rights reserved.

  6. Assessing Bleeding Risk in Patients Taking Anticoagulants

    Anticoagulant medications are commonly used for the prevention and treatment of thromboembolism. Although highly effective, they are also associated with significant bleeding risks. Numerous individual clinical factors have been linked to an increased risk of hemorrhage, including older age, anemia, and renal disease. To help quantify hemorrhage risk for individual patients, a number of clinical risk prediction tools have been developed. These risk prediction tools differ in how they were derived and how they identify and weight individual risk factors. At present, their ability to effective predict anticoagulant-associated hemorrhage remains modest. Use of risk prediction tools to estimate bleeding in clinical practice is most influential when applied to patients at the lower spectrum of thromboembolic risk, when the risk of hemorrhage will more strongly affect clinical decisions about anticoagulation. Using risk tools may also help counsel and inform patients about their potential risk for hemorrhage while on anticoagulants, and can identify patients who might benefit from more careful management of anticoagulation.

    ABSTRACT Subepithelial changes to the vocal fold mucosa, such as fibrosis, are difficult to identify using visual assessment of the tissue surface. Moreover, without suspicion of neoplasm, mucosal biopsy is not a viable clinical option, as it carries its own risk of iatrogenic injury and scar formation. Given these challenges, we assessed the ability of high- (4.7?T) and ultrahigh-field (9.4?T) magnetic resonance imaging to resolve key vocal fold subepithelial tissue structures in the rat, an...

    Cutaneous wounds heal with two possible outcomes: scarification or near-perfect integumentary restoration. Whereas scar formation has been intensively investigated, less is known about the tissue-level events characterising wounds that spontaneously heal scar-free, particularly in non-foetal amniotes. Here, a spatiotemporal investigation of scar-free cutaneous wound healing following full-thickness excisional biopsies to the tail and body of leopard geckos (Eublepharis macularius) is provided. All injuries healed without scarring. Cutaneous repair involves the development of a cell-rich aggregate within the wound bed, similar to scarring wounds. Unlike scar formation, scar-free healing involves a more rapid closure of the wound epithelium, and a delay in blood vessel development and collagen deposition within the wound bed. It was found that, while granulation tissue of scarring wounds is hypervascular, scar-free wound healing conspicuously does not involve a period of exuberant blood vessel formation. In addition, during scar-free wound healing the newly formed blood vessels are typically perivascular cell-supported. Immunohistochemistry revealed widespread expression of both the pro-angiogenic factor vascular endothelial growth factor A and the anti-angiogenic factor thrombospondin-1 within the healing wound. It was found that scar-free wound healing is an intrinsic property of leopard gecko integument, and involves a modulation of the cutaneous scar repair program. This proportional revascularisation is an important factor in scar-free wound healing. © 2015 Anatomical Society.

    Objectives: Systematic suicide risk assessment is recommended for patients with schizophrenia; however, little is known about the implementation of suicide risk assessment in routine clinical practice. The study aimed to determine the use of systematic suicide risk assessment at discharge...... and predictors of suicide attempt among hospitalized patients with schizophrenia in Denmark. Methods: A one-year follow-up study was conducted of 9,745 patients with schizophrenia who were discharged from psychiatric wards and registered in a national population-based schizophrenia registry between 2005 and 2009....... Results: The proportion of patients receiving suicide risk assessment at discharge from a psychiatric ward increased from 72% (95% confidence interval [CI]=71%-74%) in 2005, when the national monitoring began, to 89% (CI.89%-90%) in 2009. Within one year after discharge, 1% of all registered patients had...

    Patients with burns have to live with a variety of long-term physical and psychosocial consequences. Burns lead to prolonged hospital stay, disfiguring scars, disability, and even death. Since self-immolation is common in women of Iraqi Kurdistan, the present study sought to explore the experiences of women living with scars caused by self-immolation. This paper was part of a qualitative research study. A purposive sample of 18 female self-immolation survivors from Iraqi Kurdistan was selected, and 21 individual interviews were conducted and analyzed using conventional content analysis. Four categories emerged during the data analysis: (1) feelings of disbelief, regret, and anger caused by post-burn scars; (2) desperately seeking solutions; (3) grief due to disappointment and surrender to despair; and (4) rejection and isolation. In conclusion, individuals with scars and disfigurements sometimes adopted inappropriate measures to deal with the psychological problems caused by others' behaviors and wrong perceptions. Educational and support programs are hence indicated to promote awareness levels of self-immolation survivors, their families, and the whole society. Copyright © 2016 Elsevier Ltd and ISBI.

    Current methods for the estimation of infarct size by late-enhanced cardiac magnetic imaging are based upon 2D analysis that first determines the size of the infarction in each slice, and thereafter adds the infarct sizes from each slice to generate a volume. We present a novel, automatic 3D method that estimates infarct size by a simultaneous analysis of all pixels from all slices. In a population of 54 patients with ischemic scars, the infarct size estimated by the automatic 3D method was compared with four established 2D methods. The new 3D method defined scar as the sum of all pixels with signal intensity (SI) ≥35 % of max SI from the complete myocardium, border zone: SI 35-50 % of max SI and core as SI ≥50 % of max SI. The 3D method yielded smaller infarct size (-2.8 ± 2.3 %) and core size (-3.0 ± 1.7 %) than the 2D method most similar to ours. There was no difference in the size of the border zone (0.2 ± 1.4 %). The 3D method demonstrated stronger correlations between scar size and left ventricular (LV) remodelling parameters (LV ejection fraction: r = -0.71, p 3D automatic method is without the need for manual demarcation of the scar; it is less time-consuming and has a stronger correlation with remodelling parameters compared with existing methods.

    Purpose: This study was designed to compare the effectiveness of systemic methotrexate (MTX) with uterine artery embolization (UAE) combined with local MTX for the treatment of cesarean scar pregnancy (CSP) with different ultrasonographic pattern, and to indicate the preferable therapy in CSP patients. Methods: The results of 21 CSP cases were reviewed. All subjects were initially administrated with systemic MTX (50 mg/m 2 body surface area). UAE combined with local MTX was added to the patients who had failed systemic MTX. The transvaginal ultrasonography data were retrospectively assessed, and two different ultrasonographic patterns were found: surface implantation and deep implantation of amniotic sac. The management and its effectiveness for patients with the two ultrasonographic patterns were studied retrospectively. Ultrasound scan and serum β-hCG were monitored during follow-up. Data were analyzed with the Student’s t test. Results: Nine patients were successfully treated with systemic MTX. The remaining 12 cases were successfully treated with additional UAE combined with local MTX. According to the classification by Vial et al. of CSP on ultrasonography, most surface implanted CSPs (8/11, 72.7%) could be successfully treated with systemic MTX, whereas most deeply implanted CSPs (9/10, 90%) had failed systemic MTX but still could be successfully treated with additional UAE combined with local MTX. All patients recovered without severe side effects. Most patients with a future desire for reproduction achieved subsequent pregnancy. Conclusions: For CSP patients suitable for nonsurgical treatment, UAE combined with local MTX would be the superior option compared with systemic MTX in the cases with deep implantation of amniotic sac.

    In this study, we aimed to determine the relation of TLR-4 Asp299Gly and Thr399Ile polymorphisms and monocyte/neutrophil TLR-4 expression to febrile urinary tract infection (UTI) and renal scar development in children. The study was performed in children with a history of febrile UTI. Patients with and without renal scarring were classified as group 1 and group 2, respectively, while the control cases in our previous study were used as the control group (group 3). All three groups were compared for the rate of TLR-4 Asp299Gly and Thr399Ile polymorphisms, and for basal and lipopolysaccharide-stimulated monocyte/neutrophil TLR-4 expression levels. There were 168 patients (86 in group 1, 82 in group 2) and 120 control cases. Monocyte/neutrophil TLR-4 expression levels were similar in groups 1 and 2. However, both groups had lower TLR-4 expression than group 3. The rate of TLR-4 Asp299Gly polymorphism was not different in all groups. TLR-4 Thr399Ile polymorphism was higher in groups 1 and 2 than in group 3 (14.0, 12.2, and 2.0 %, respectively), while group 1 and group 2 were not different. Furthermore, monocyte TLR-4 expression level was lower in those having TLR-4 Thr399Ile polymorphism than in those without this polymorphism. Patients with febrile UTI had more frequent TLR-4 Thr399Ile polymorphism and lower monocyte/neutrophil TLR-4 expression. These findings indicate that children carrying TLR-4 Thr399Ile polymorphism and/or having low level of monocyte/neutrophil TLR-4 expression have a tendency to develop febrile UTI. However, we could not show the association of TLR-4 polymorphisms and of TLR-4 expression level to renal scarring.

    Assessment of the presurgical patient requires interdisciplinary cooperation over the continuum of documentation and optimization of existing disorders, determination of patient resilience and reserve, and planning for subsequent interventions and care. For many patients, evident or suspected morbidities or anticipated surgical disturbance warrant specialty consultation. There may be uncertainty as to the optimal processes for a given patient, a limitation attributable to myriad factors, not the least of which is that there is often a paucity of evidence that is directly relevant to a given patient in a given setting. The present article discusses these limitations and describes a framework for documentation, optimization, risk assessment, and planning, as well as a uniform grading of existing morbidities and anticipated perioperative disturbances for patients requiring integrated assessment and consultation.

    There is currently many over the counter products on the market that exert nutritional or physiological effects on the human body. The differences between dietary supplements and non-prescription drugs are however poorly understood by the average consumer and may thus affect their expectations as to the desired effect produced on the body. To evaluate patients' knowledge and attitudes towards dietary supplements as compared to non-prescription drugs. Subjects were 335 patients of the Mazowiecki Voivodeship Hospital in Warsaw, Poland. The data were collected from a face-to-face interview using a single and multiple choice questionnaire with 10 questions on dietary supplements. Statistical analysis used the Chi-square (χ2) test. The majority of respondents were found to be familiar with the term 'dietary supplements', but had difficulties in classifying these products into appropriate categories. Over 55% do not consider dietary supplements to be foodstuffs and more than 40% considered such products to be drugs. Most respondents thought that the main purpose of taking dietary supplements is to improve nutrition, but over one third expected them to also treat disease. Over 70% declared taking notice to which category the non-prescription products they bought belongs to ie. whether non-prescription drugs (medicinal products) or dietary supplements. Many patients mistakenly believe that dietary supplements are drugs and can be used to treat disease and health disorders. dietary supplements, opinion on dietary supplements, nutrition, dietary supplement vs. medicinal product.

There is currently a lack of evidence regarding the self-reported concerns of SCT patients before and after SCT.Aim and design: This exploratory study performed a secondary analysis of self-reported, written concerns of SCT patients before and after transplant to determine patients' concerns.Methods: Content analysis of text box entries of SCT patients collected between 2005 and 2007 at the Seattle Cancer Care Alliance. Text box entries were collected as part of symptom assessment using the Electronic Self-Report Assessment – Cancer instrument. The assessment was presented to 137 patients undergoing SCT at two time points: prior to ambulatory visits before any therapy had begun (T1 and at the first visit after hospital discharge following SCT (T2.Results: Text box entries were made before (n = 52 and after (n = 87 the transplant, resulting in 139 text box entries made by 137 patients representing 133 concerns. Using content analysis, the entries were categorized and ranked according to frequency. After symptom concerns, patients ranked work and financial issues the most frequent concerns prior to SCT. After SCT, symptoms remained the most frequently entered area of concern, followed by survival.Conclusion: Oncology providers need to assess SCT patients for work and financial concerns before and after transplant. Appropriate and timely referrals may ease the burden of these concerns for patients. Thus, assessment of financial and work concerns by the oncology team should be an integral part of quality health care for patients undergoing SCT.Keywords: self-report, electronic

    Stroke patients can experience a variety of pain. Many stroke patients have co-morbidities such as osteoporosis, arthritis or diabetes causing diabetic neuropathy. As well as pain from other long term conditions, stroke patients can experience central post-stroke pain, headaches, and musculoskeletal issues such as hypertonia, contractures, spasticity, and subluxations. These stroke patients can also have communication difficulties in the form of expressive dysphasia and/or global aphasia. Communication difficulties can result in these patients not expressing their pain and therefore not having it assessed, leading to inadequate pain relief that could impact their rehabilitation and recovery. By implementing an observational measurement of pain such as the Abbey pain scale, patients with communication difficulties can have their pain assessed and recorded. Initially 30% of patients on the acute stroke ward did not have their pain assessed and adequately recorded and 15% of patients had inadequate pain relief. The patient was assessed if they were in pain and therefore not receiving adequate pain relief by measuring their pain on the Abbey pain scale. After introducing the Abbey pain scale and creating a nurse advocate, an improvement was shown such that only 5% of patients did not have their pain recorded and all had adequate pain relief.
