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

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

Hyaluronic acid-based fillers in patients with autoimmune inflammatory diseases.

The use of hyaluronic acid (HA)-based aesthetic therapies is growing steadily, and according to the International Society of Aesthetic Plastic Surgery, more than 4.3 million aesthetic procedures using HA were performed in 2019, an increase of 15.7% than 2018. More people are offering these types of services, often without proper training or qualifications. Therefore, there is an increasing number of reports in the literature relating to possible adverse events, with subsequent therapeutic problems and more or less serious consequences for patients. The aim of this research is to carry out a review of the literature in order to evaluate the impact of hyaluronic acid-based fillers in patients with autoimmune inflammatory diseases, in particular scleroderma and Systemic Lupus Erythematosus (SLE). Although HA plays a central role in the inflammatory process, the use of HA-based fillers in patients with autoimmune inflammatory diseases is still controversial. HA, in fact, in inflamed tissues helps to propagate the inflammatory response and, injected in the form of a dermal filler, could potentially promote reactivation of the underlying disease. For this reason, many specialists do not perform HA-based aesthetic treatments in patients with scleroderma or SLE. However, recent scientific evidence suggests that the use of HA-based fillers in patients with scleroderma can lead to improvement of skin lesions, with satisfactory results. In the literature, there are no clinical studies that contraindicate the administration of HA-based dermal fillers in patients with inflammatory disease.

Correction of Rippling in Implant-based Breast Reconstruction with Serratus Fascia Flap.

Implant-based breast reconstruction represents the most popular procedure for the treatment of women undergoing skin-sparing mastectomy. In selected patients, it allows for obtaining an excellent appearance of the reconstructed breast with great satisfaction to the patient. However, aesthetic and functional results can be affected by complications requiring reoperation. Among them, rippling is an undesired occurrence associated with implant-based reconstruction. It consists of a cutaneous manifestation, visible and/or palpable, of the implant wrinkles and edge which appear mostly when the patient leans forward. To treat this contour deformity, several techniques have been described such as acellular dermal matrices and autologous tissues. In this study, we intend to add the serratus anterior fascial flap within the autologous options in the treatment of implant rippling, reporting our experience.

Tuberous Breast Management: A Review of Literature and Novel Technique Refinements.

The tuberous breast is a rare malformation that can affect psychosocial well-being in young women. Its management represents a great challenge to plastic surgeons. Many surgical procedures have been described to correct different grades of tuberous breast deformity (TBD). The authors describe their one-stage technique for correcting grade 2 TBD. Methods: Sixteen women affected by grade 2 TBD treated with glandular flaps, silicone gel prosthesis, and only an hemiperiareolar incision between January 2018 and January 2019 were reviewed. The age range was 19-27 years (mean age was 25). Follow-up average was 25 months (range 16-33 months). To evaluate the results, we used two analogic scales with values from 1 to 3, where the lower value was the worst result. First, an independent medical team of three plastic surgeons evaluated two parameters: correction of deformity and symmetry. Then, patients were asked to judge the result obtained. Results: The resulting breast has a normal-shaped areola without bulging, a natural shape, a volume matching the contralateral breast, and no evidence of "double-bubble" deformity or irregularities of the lower pole shape. Conclusion: We propose this one-stage approach with hemiperiareolar incision, to minimize time interval to obtain final results in TBD correction, with reduced scar dimensions to avoid all the possible complications related to the round block suture.

Successful Treatment of Wound Dehiscence by Innovative Type 1 Collagen Flowable Gel: A Case Report.

The growing demand for postbariatric body-contouring surgery after massive weight loss goes hand-in-hand with an increase in wound complications. Consequently, surgical reoperation or conservative management is necessary and represents a difficult challenge to healthcare professionals. Moreover, it is well known that postbariatric patients present aberrant wound healing due to multifactorial causes, such as preoperative illness, nutritional deficiencies, and vascular disease. To treat such complex wounds, several methods have been recommended, such as the use of negative pressure wound therapy, tissue-engineered skin substitutes, and collagen-based wound dressings. The case presented here is of a patient with deep wound dehiscence of the inner left thigh, 1 week after a medial thigh lift procedure, successfully managed with Vergenix Flowable Gel, a human recombinant type I collagen produced in plants. After 2 weeks of treatment, wound dehiscence was replaced with granulation tissue, and after 4 weeks, the patient was completely healed, with an acceptable aesthetic outcome of the surgical scar.

The "Five-flap" Technique for Nipple-Areola Complex Reconstruction.

Nipple-areola complex reconstruction aims to be the last step in the postmastectomy treatment procedure. Different techniques have been developed with the purpose of achieving optimal symmetry in position, size, shape, pigmentation, and permanent projection of the reconstructed nipple, but to date, there is no gold standard technique. The five-flap technique provides an easy, simple nipple-areola complex reconstruction method, effectively maintaining longer nipple projection, with a negligible rate of complications. METHODS: From November 2018 to April 2021, a total of 21 female patients with an absent unilateral nipple-areolar complex due to postoncological mastectomy were subjected to our technique consisting of a combination of local flaps and a full-thickness skin graft. Patients were observed for 6 months to estimate the percentage of the nipple projection loss. Overall satisfaction was evaluated by the patients themselves and by an external medical observer at the end of the follow-up period. RESULTS: None of the reconstructed nipples experienced either total or partial necrosis. Two minor complications were observed. Nipple projection loss was negligible with an average reduction of 12% from the initial projection. The nipple-areolar complex shape remained excellent in all cases, with minimal alteration of the immediate postoperative results. The total average satisfaction score was 8.0 for patients and 9.0 for external observers. CONCLUSION: The five-flap technique represents a simple, safe, and efficacious procedure in patients with implant-based reconstruction requiring moderate to very projected nipples.
