The effects of kiwifruit dressing on hypertrophic scars in a rabbit ear model.

AIMS: Hypertrophic scars show abnormal responses during healing. These scars, associated with dysregulated growth and excessive collagen formation, can have both functional and cosmetic consequences for patients. The present study evaluated the effects of kiwifruit on hypertrophic scars in a rabbit ear model. METHODS: This study included 13 New Zealand albino rabbits with full thickness wounds down to the cartilage (four wounds per ear; total: 104 scars). Sixteen days after initial wound formation, one ear of each rabbit was treated with daily kiwifruit dressing, while the other ear (control group) was dressed after normal saline irrigation for 10 days. Harvested skin samples were examined for histopathological, morphometric and immunohistochemical results. RESULTS: In comparison with the control group, early kiwifruit dressing significantly reduced the scar elevation index, fibroblast count and dermal collagen organisation. The ratio of collagen type III to total collagen immunoreactivity, inflammation and dermal capillary count increased significantly in the treated group, compared to the untreated controls. CONCLUSION: Based on the findings, early kiwifruit dressing improved the histological features of cutaneous wounds in rabbits. Therefore, this approach may be effective in clinical practice.

Satisfaction and Functional Outcome of Surgical Treatment in Patients with Brachial Plexus Injury: A Decade of Retrospective Comparative Study.

Background: Brachial plexus injury (BPI) is a severe peripheral nerve injury resulting in physical disability. Few studies have investigated the postoperative functional status. We aimed to evaluate the satisfaction with surgical treatment in patients with BPI referred to the Panzdah-e Khordad Hospital, Tehran, Iran from 2011 to 2021. Methods: In this descriptive-analytical retrospective comparative study, physical examination, along with BrAT, and DASH questionnaires were used to evaluate the patients' status. Then the collected data on the patients' functional status and movements were collected. To compare the mean of quantitative variables before and after the surgery, the dependent t-student was used. Results: Generally, the patients stated that they still had considerable difficulty doing most of the items of the questionnaires. Nevertheless, there was a significant difference between the following variables before and after surgery; shoulder abduction goniometry (0-150) and force (M0:M5), shoulder external rotation goniometry (0-90) and force (M0:M5)), shoulder forward flexion goniometry (0-180) and force (M0:M5)), elbow flexion goniometry (0- 150), elbow extension force (M0:M5), and wrist and finger muscle force (M0:M5) (P<0.001). Conclusion: Posterior approach in BPI surgery was associated with good outcomes in terms of shoulder external rotation and abduction. However, patients still suffered from difficulties in daily activities.

Impact of COVID-19 pandemic on plastic surgery activities and residency programs in a tertiary referral centre in Iran.

Background: On March 11, 2020, the World Health Organization (WHO) announced the COVID-19 outbreak as a new pandemic. In the meantime, plastic surgeons postponed their appointments due to the fair and rational allocation of medical supplies. These limitations made all junior and senior residents perform operations only on traumatic patients rather than those needing reconstructive procedures. This study aims to determine the effects of the COVID-19 pandemic on plastic surgery training programs in Iran. Also, the number of canceled surgeries will be determined to see the effects of the pandemic on the patients. Methods: This retrospective case study considers a six-month timeframe in two consecutive years before and after the COVID-19 pandemic. For this purpose, the researchers evaluated the number of surgeries, types of procedures, age distribution, and gender distribution. The training program data of plastic surgery residents were collected from their logbooks and then analyzed in IBM SPSS Statistics 26. Differences were considered significant if p < 0.05 at a 95% confidence level. Results: The total number of surgeries decreased by 23.5% after the COVID-19 outbreak (p < 0.05). There was a 29.9% reduction in trauma cases, -78.9% in aesthetic surgeries, -17.7% in reconstructive surgeries, -51.8% in craniofacial surgeries, and -59.5%in microscopic surgeries for each resident. Conclusions: This study provides an insight into the severity of the pandemic effects on the plastic surgery training programs and the patients. The reduced number of surgeries led to a depletion in surgical skills training. These effects will not wear off immediately after the pandemic; therefore, it is necessary to observe whether the pandemic will have any lasting effects on this subspecialty.Level of evidence: Level IV, risk/prognostic study.

Correcting Flank Skin Laxity and Dog Ear Plus Aggressive Liposuction: A Technique for Classic Abdominoplasty in Middle-Eastern Obese Women.

BACKGROUND: Nowadays obesity is a common problem as it leads to abdominal deformation and people's dissatisfaction of their own body. This study has explored using a new surgical technique based on a different incision to reform the flank skin laxity and dog ear plus aggressive liposuction on women with abdominal deformities. METHODS: From May 2014 to February 2016, 25 women were chosen for this study. All women had a body mass index more than 28 kg/m2, flank folding, bulging and excess fat, abdominal and flank skin sagging and laxity. An important point of the new technique was that the paramedian perforator was preserved. RESULTS: All women were between 33 and 62 years old (mean age of 47±7.2 years old). The average amount of liposuction aspirate was 2,350 mL (1700-3200 mL), and the size of average excised skin ellipse was 23.62×16.08 cm (from 19×15 to 27×18 cm). Dog ear, skin laxity, bulging and fat deposit correction were assessed and scored in two and four months after the surgery. CONCLUSION: Aggressive abdominal and flank liposuction can be safely done when paramedian perforator is preserved. This has a good cosmetic result in the abdomen and flank and prevents bulging in the incision end and flank. Using this abdominoplasty technique is recommended on patients with high body mass indexes.

Lateral lower face and neck contouring following burn injury.

The neck is normally a concave and highly mobile structure. Facial and cervical skin is prone to burn scar contracture because of its thin nature. The goal of treatment is to reconstruct this region to achieve a good aesthetic outcome and also normal neck and chin mobilization. This study was conducted to compare the effect of one row of suture and three rows of suture in critical points of the neck to recreate cervicomandibular angle for better contouring of the neck. A cross-sectional study was performed from July 2006 until August 2010. A total of 65 patients underwent lower lateral face and neck burn scar contracture reconstruction. The mean age of participants was 25.5 years old. After designing a local flap, in 31 patients we applied one row of suture. In 34 patients, we used three rows of suture on each side of the neck incorporation with  the recipient bed and the flap dermis or capsule to recreate a natural lower lateral face and neck contour (P<0.001). The standard deviation in hospitalization was 7 ± 2 days for group A and 6 ± 1 days for group B. In a two years follow-up, no blunting of cervicomandibular angle occurred and three rows of suture were superior according to present findings.

Re-creation of the Inframammary Fold, Breast Mound, and Projection by the Latissimus Dorsi Musculocutaneous Flap in Burned Breasts.

OBJECTIVE: Some of the most difficult problems to solve in a postburn breast are the correction of the breast mound deficiency, contour, and projection deformity, which are often associated with an anterior trunk scar. The aim of this study was to describe our experiences of postburn breast reconstruction by the island latissimus dorsi musculocutaneous flap (LDMCF). METHOD: Operative procedures were planned after measuring the volume, dimensions, sternal notch-to-nipple distance, deviation, asymmetry, contour, and projection. Scar contracture release was carried out and complete muscle elevation was performed in all patients. The size of the skin paddle depended on the envelope deficiency. Afterward, LDMCF was transferred by a subcutaneous tunneling, and the muscle was sutured in retroglandular, inferomedial, and inferolateral ways to shape the inframammary fold (IMF) contour, breast mound, and projection. The skin of the flap was trimmed to match the envelope deficiency. RESULT: A total of 9 burned patients (11 breasts), who had burnt anterior trunks due to scalds and flame, entered the study. They were reconstructed by LDMCF. The patients achieved breast contour (re-creating the IMF), projection, and breast mound increase. The means of breast mound and projection increase were about 140 mL and 2.5 cm, respectively. CONCLUSIONS: This study demonstrates that the method used for reconstructing the burned breast depends on the patient's clinical presentation. For the patients with anterior trunk scar who have breast mound deficiency, IMF, and projection deformity, LDMCF is one of the best options of reconstruction.
