In this article, the author undertakes a review of different methods of breaking up scars by utilizing zigs and zags, and conducts a pigskin study to measure the reduction in tension that can be achieved by using a simple zigzag technique while performing excisions. Methods: A pigskin study conducted into the use of the simple zigzag to reduce the tension (and thereby scarring) of surgical wounds is reported here, and comparison and review is undertaken of the biomechanics of elliptical excisions and traditional Z-plasties. Results: Using a simple zigzag reduces tension across the midpoint of the scar more effectively than a Z-plasty or a simple elliptical excision. Conclusion: The techniques of breaking up a scar or incision line by using zigs and zags, in a means to reduce scarring, are not new. However, each of these techniques has specific advantages and disadvantages that need consideration by the surgeon. In this paper, a pigskin study is conducted into the use of the simple zigzag to reduce the tension (and thereby reduce the risk of poor scarring) of surgical wounds.展开更多

This analysis evaluates the efficacy of tamanu oil in acne treatment with a specific focus on its impact on inflammation and scar reduction. The novelty of this research lies in its comprehensive analysis of tamanu oil’s dual mechanism of action: reducing acne-related inflammation and promoting the healing of acne scars. Clinical trials and laboratory analyses were conducted to assess the oil’s effectiveness in diminishing erythema, swelling, and post-acne scarring compared to conventional treatments. Preliminary findings demonstrate that tamanu oil significantly reduces inflammation and accelerates wound healing, potentially offering a promising adjunct or alternative to standard acne therapies. Future research should aim to optimize formulation and application protocols, long-term effects, and comparative therapeutic efficacy with other anti-inflammatory agents. Tamanu oil offers a novel and effective approach to acne management, with potential advantages that go beyond inflammation reduction to include enhanced scar reduction, making it a subject that warrants further investigation.展开更多

For this indication, vaginal hysterectomy constitutes an alternative to vaginal expulsion with a high risk of uterine rupture and to classic abdominal cesarean section with risk of significant surgical trauma, particularly adhesions. However, this surgical technique, described since the 19th century, remains unknown to many practitioners and few publications exist on the subject throughout the world. Considered obsolete by some practitioners, it retains all its advantages in the practice of modern obstetrics. We report this case of expulsion of fetal death on a tri-scarred uterus performed by vaginal cesarean section at the Health District Reference Health Center (District Hospital) of Commune I in Bamako, Mali in a 37-year-old patient with a pregnancy of 27 weeks of amenorrhea.展开更多

Keloid scars, however, are a type of abnormal and exacerbated repair response to tissue injury, whether in surgical interventions or in various injuries, which present in a prominent and gross way. In this context, there is an excess of collagen deposition in the tissue repair process, which can lead to the formation of keloids. The diagnosis of the condition presented is made by the medical professional or by the patient himself after the surgical intervention or skin injury. Under this analysis, protruding, rough and bad-looking scars are identified. In addition, we highlight the existence of keloids similar to large tumors, described as Jorge Lobo disease. The treatment encompasses massages, compressions, corticosteroids, chemotherapy, collagenase and cryotherapy. At first, we used corticosteroid-based massages, and then we started using compressive dressings until we started intrakeloid infiltrations with injectable triamcinolone. Triamcinolone 10 mg injectable—1/10—in 0.9% saline, with syringe and fixed needle 0.3 mm × 8 mm, intralesional infiltrate, in this context, proved to be effective for its treatment when applied sequentially and linearly. In cases where the medication was applied, there was an improvement after 21 days of application and a definitive improvement 2 months after the injury. In comparison, on the other hand, patients who were not subjected to the application of the medication may improve after 4 months of the injury or worsen compared to the initial case. We have come to the conclusion that this procedure may be one of the chosen ones for the treatment of keloid scars, being one of the most recommended for cases of keloid already installed.展开更多
