Preference for donor site scar orientation in pedicled latissimus dorsi breast reconstruction

A survey was carried out to ascertain the preference for donor site scar orientation in patients undergoing pedicled latissimus dorsi breast reconstruction and their views on breast reconstruction in general. One hundred twelve women (59 Chinese, 53 Western) completed the questionnaire. Participants were asked to state their preferred scar orientation (i.e., oblique, horizontal, or vertical) based on photographs showing the position of the scars. Demographic information and views on issues surrounding breast reconstruction in general were also collected. Data was analyzed non-parametrically with chi-square test and t test. The mean age of participants was 39.5 years (20–73 years). Seventy-seven percent of the participants would opt for an immediate breast reconstruction if offered (p < 0.001). Eighty-six percent would have objection to the use of silicone implant as a whole or part of a reconstruction (p < 0.001). Vertical and horizontal scars were the preferred orientation, with no women choosing the oblique orientation as their first choice (p < 0.001). The non-Chinese of 40 years or older, as well as Chinese women from all age groups, preferred the horizontal scar (p < 0.05). We demonstrated that both culture and age impact on the preferred scar orientation in breast reconstruction. Women in the age group we commonly reconstruct favored the horizontal scar. However, the younger women of non-Chinese origin tended to favor the vertical scar.     

丹参在抑制兔唇创口瘢痕增生中的作用

选用50只新西兰白兔,2只处死后取上唇组织作为病理对照,48只采用Millard’s法修复上唇裂隙,拆线后随机分为实验组、溶媒组和对照组3组,每组16只。实验组每天涂擦复方丹参膏2次,溶媒组每日涂擦溶媒膏二次,对照组不作任何处理。分别在术后0d、7d、15d、21d、30d、60d、90d测量上唇瘢痕的体积变化,并在7d、30d、60d时每组分别处死2只,90d后全部处死,取上唇瘢痕组织在光镜和电镜下观察组织病理学变化。组织学观察显示丹参可抑制成纤维细胞增殖,影响胶原蛋白合成,使胶原纤维重排和降解,从而减轻瘢痕增生。     

单向中频电加助透液防治瘢痕增生

为防治瘢痕增生，寻求有效治疗方法，我们采用单向中频电加助透液治疗瘢痕增生患者３３例，痊愈显效率为６４％，总有效率为８８％。结果表明，单向中频电加助透液能增强导入作用，是防治瘢痕增生的有效方法。     

A theoretical consideration of extensions of the Z-plasty principle

For the release of congenital or posttraumatic webs a variety of local skin flap techniques have been described. Confusion exists on how much lengthening may be obtained by each of these techniques, as well as on how much lateral slack is needed for the flaps to be shifted. These techniques and the results they provide are reviewed, calculated, and visualized by diagrams. It is concluded that the Z-plasty and its modifications lead to superior lengthening-to-narrowing ratios. Combined YV-plasties have their advantage in that resection of scarred skin will be obtained. Position, extent and orientation of the scar or web will generally indicate which technique is to be used in each individual case.     

Scar endometriosis—a gynaecologic pathology often presented to the general surgeon rather than the gynaecologist: report of two cases

Introduction Scar endometriosis develops in and is adjacent to surgical scars at the site of previous abdominal operations. The most frequent clinical presentation of the disease is that of a palpable subcutaneous mass near surgical scars associated with cyclic pain and swelling during menses. Endometriosis of the surgical scar is often referred to the general surgeons because the clinical presentation suggests an incisional hernia or other conditions related to the general surgery. Cyclical symptoms such as pain and swelling, in relation to surgical scars, which worsen at the time of menstruation, are nearly pathognomonic of scar endometriosis. However, often the diagnosis of endometriosis is not suggested until after histology has been performed. Case report We present two cases of cutaneous endometriosis that has occurred on the site of previous cesarean section scar area.     

Abordajes en cirugía tiroidea

Thyroidectomy is the most frequent procedure in endocrine surgery. The conventional approach through a collar incision, as described by Kocher in XIX^th century, has become the “gold standard”. It is continuously evolving in spite of, many years ago, it showed to be safe and efficient with quality standards difficult to beat.Endoscopic and robotic surgery have developed “new approaches” to thyroid in order to improve the cosmetic results, looking even for invisible scars.We have done a thoughtful review of most of them trying to understand their benefits and drawbacks.Currently none of these “new approaches” have been shown to be better than conventional open thyroidectomy beyond offering a better cosmetic result. Besides, only a small percentage of patients can benefit of them. However, most of these approaches will remain if they treat the diseased thyroid and also improve the quality of life of our patients.     

Skin expansion in burn patients: problems, rules and indications

Skin expansion in burn patients can be a useful method for secondary skin resurfacing, scar revision or facial remodelling. However, complications and problems occur more often in these patients than in any other. In this paper the incidence of complication in the first and second stages of expansion will be presented. Several rules will then be stated and we will clarify the indications for skin expansion in the treatment of hypertrophic scars, contractures, and post-burn destructions.Lecture given at the first State of the art course on burn reconstruction — Milano, May 1994     

活血生肌法抗瘢痕作用机理的实验与临床研究

目的 探讨活血生肌法抗瘢痕的作用机理与疗效。方法 动物实验用大鼠造模后随机分为三组：治疗Ⅰ组、治疗Ⅱ组、对照组。分别给予半导体激光照射、活血生肌疗法(生肌活血油 半导体激光照射)、碘伏纱布处理。取创面肉芽组织及其血液，测定纤维连接蛋白(Fn)及创面碱性成纤维因子(b-FGF)的含量，同时观察伤口愈合情况，进行比较。临床研究：以76例腋臭术后切口为抗瘢痕研究对象，分为A、B、C三组(A组对照组、B组治疗Ⅰ组、C组治疗Ⅱ组)。三组除常规用药外，B组与C组再分别给予半导体激光照射及活血生肌疗法(生肌活血油 半导体激光照射)治疗。结果 动物实验表明，治疗Ⅱ组可明显提高血液及肉芽组织中Fn的含量；在创面修复的炎症和增殖期b-FGF水平可显著增加，在塑形期b-FGF水平降低；改善创面血液循环，促进中性粒细胞浸润和巨噬细胞的游出，提高局部抗感染能力；加速新陈代谢，与治疗Ⅰ组、对照组相比具有显著性差异。C组在切口周围肿胀程度、疼痛缓解时间、愈合时间、切口愈合瘢痕宽度、病人满意程度等指标方面明显优于A、B组。结论 活血生肌疗法具有消肿胀、生新肌、通血脉、抗瘢痕的作用。
