[Comparison of breastfeeding duration in women before and after breast reduction surgery]. / Comparaison de la durée d'allaitement maternel chez les femmes avant et après mammoplastie de réduction.

BACKGROUND: Breast reduction surgery often concern women of childbearing age. However, it can interfere with the ability to breastfeed, whereas the benefits of breastfeeding are well known. Current data in the literature do not provide precise information on the possibilities of breastfeeding after breast reduction surgery. OBJECTIVES: The aim of this study was to assess long-term breastfeeding ability of women after breast reduction performed in our centre. METHODS: This is a retrospective comparative study including patients treated with breast reduction at Saint-Louis Hospital between 2010 and 2017 and who have had children before or after surgery. Operative details were retrieved from medical records and ability to breastfeed was assessed during a phone interview. Breastfeeding before surgery was compared to breastfeeding after surgery. RESULTS: We analysed 21 births before and 35 births after breast reduction. Breastfeeding initiation was similar in the two groups (90% vs. 83%, P=0.7), but the median duration was significantly shorter after breast reduction compared with before (3 weeks vs. 10 weeks; P<0.01), the rate of breastfed child at 3 months was lower after surgery (11% vs. 43%; P<0.01), the use of infant formula was higher after surgery (100% vs. 74%, P<0.01), and we found a higher rate of discontinuation caused by hypogalactia (69% vs. 11%; P<0.001). CONCLUSION: Breastfeeding is possible but more difficult to sustain over time after breast reduction. Patients need to be made aware of that before surgery, and patients who still want to breastfeed should be encouraged at the maternity.

In vitro effects of wound-dressings on key wound healing properties of dermal fibroblasts.

Healing of complex wounds requires dressings that must, at least, not hinder and should ideally promote the activity of key healing cells, in particular fibroblasts. This in vitro study assessed the effects of three wound-dressings (a pure Ca2+ alginate: Algostéril®, a Ca2+ alginate + carboxymethylcellulose: Biatain alginate® and a polyacrylate impregnated with lipido-colloid matrix: UrgoClean®) on dermal fibroblast activity. The results showed the pure calcium alginate to be non-cytotoxic, whereas the other wound-dressings showed moderate to strong cytotoxicity. The two alginates stimulated fibroblast migration and proliferation, whereas the polyacrylate altered migration and had no effect on proliferation. The pure Ca2+ alginate significantly increased the TGF-ß-induced fibroblast activation, which is essential to healing. This activation was confirmed by a significant increase in Vascular endothelial growth factor (VEGF) secretion and a higher collagen production. The other dressings reduced these fibroblast activities. The pure Ca2+ alginate was also able to counteract the inhibitory effect of NK cell supernatants on fibroblast migration. These in vitro results demonstrate that tested wound-dressings are not equivalent for fibroblast activation. Only Algostéril was found to promote all the fibroblast activities tested, which could contribute to its healing efficacy demonstrated in the clinic.

Brûlures chimiques: notre série sur 25 ans.

Chemical burns raise diagnostic and treatment issues because they have specific appearances and evolution. Our objective was to study the characteristics of chemical burns and to assess the quality of our treatment. This retrospective observational study examined the records of all patients admitted for chemical burns to the burn treatment center of Saint Louis Hospital in Paris from January 1, 1990, through December 31, 2015. During this period, 162 patients came to our center for chemical burn treatment. Most of them were men (67%). The majority of the burns were caused by alkalis (27%) and resulted from workplace accidents (29%). The average time before consultation was 5.36 days. The areas mainly damaged were the hands (36%) and the burn areas averaged 1.2% of the total body surface area (TBSA). Forty-eight patients had at least one deep patch. In total, 59 patients (36.4%) were hospitalized for an average duration of 4.18 days. Thirty-eight of them underwent surgery. Lastly, 92% of the operations had been anticipated from the first consultation. In our center, the population affected, the circumstances and the topography of our patients' burns were similar to the data from the literature. It appears that the principal specificity of our series is a very low body surface burned. This can be attributed to the prevention measures we have in France and underlines their importance. Only 8% of the patients who had surgery were underestimated or their burns became deeper secondarily. This number is lower than the data from other series.

[Greater omentum flap: Treatment of chronic wounds and seroma: About a case]. / Le lambeau de grand épiploon : traitement des plaies et lymphorrhees chroniques : à propos d'un cas.

INTRODUCTION: Cicatricial complications after abdominal or pelvic surgery are more frequent in obese patients. In this case, infection, seroma and delays in scarring can be extremely difficult to treat. The objective of this technical note is to present an original case of an obese patient operated nine years ago of a hysterectomy by laparotomy and chronically presenting a non-resolving septic seroma despite multiple surgical procedures whose healing could be obtained by a flap of greater omentum. SURGICAL TECHNIQUE: The ideal is to carry out this intervention in a double team with a digestive surgeon in case of intra-abdominal visceral or vascular wound during dissection. The greater omentum flap was raised in a conventional manner over the gastroepiploic artery. A sufficiently wide orifice should be left at the level of the abdominal aponeurosis in order to avoid any compression of the pedicle. Finally, the flap must be spread over the whole surface of the detachment and fixed to the anterior aponeurosis. CONCLUSION: Reliability and vascular and lymphatic richness make the greater omentum flap a very effective method in chronic wound cases associated with important seroma. The scarring obtained in the clinical case presented thus highlights the specific qualities of this flap.

Our 35 years' experience on postburn heterotopic ossification: A three-step treatment.

Our retrospective study of burn patients presents a three-step treatment of heterotopic ossification: excision surgery, early rehabilitation, and analgesia. We included patients admitted to the department for treatment of postburn heterotopic ossification between January 1, 1979, and September 30, 2015. The mean age at the time of the burn was 43.3 years. Men accounted for the majority of burn patients who developed an osteoma (70.8%). The mean total skin area burned was 38.4%. No osteoma justifying surgery was found for any patient with a total burned skin area less than 19%. The burned zones were related to the osteoma development in 94.3% of cases. On average, the surgery took place 10.8 months after the burn. The osteotomy was accompanied by surgical treatment of a contracture in 37.1% of patients. Most of the osteomata were found at the elbows (30), followed by the shoulders (3), and finally the knees (2). Rehabilitation began on D0 after the surgery, except if a flap or a thin-skin graft was used. Regarding analgesia, opiates were prescribed systematically during the immediate postoperative period. Elbow range of motion on flexion improved by a mean of 84.1°. During the postoperative period, we found 2 recurrences of osteoma and 1 elbow hematoma in two separate patients. There were no postoperative infections or neurological sequelae. Our retrospective French study confirmed results found in the international literature. The three-step treatment - excision surgery, early rehabilitation, and antalgia - seems to be the best means of treating osteoma with satisfactory results. Surgery is indicated only in the case of functional impairment and not simply based on imaging.

[Management of hypopigmented scars following burn injuries]. / Prise en charge des cicatrices hypopigmentées post-brûlure.

OBJECTIVE: Permanent hypopigmentation of burn scars is a common consequence after partial and full thickness burns that heal by secondary intent, and they can cause severe aesthetic issues. The surgical goals for effective treatment of postburn hypopigmentation are to remove scar tissues, and to produce healthy melanocytes, with minimal donor site morbidity. This article reviews the current literature about the different ways to treat hypopigmentation following burn injuries and discusses the indications. METHODS: The PubMed database was searched for articles published from 1985 and up to 2016. Papers with regards to the management of hypopigmented lesions were included only if scars were following burn injuries. The treatments were assessed according to body region treated, surface involved, skin color, effectiveness on restoring skin pigmentation. RESULTS: Sixteen studies were included in this review. Non-surgical treatments like makeup and tattooing, and surgical treatments including thin skin grafting, chip skin grafting, punch grafting, non-cultured keratinocyte-melanocyte cell suspension, and cultured epidermal cells were all compared. CONCLUSION: Thin skin grafting is a reliable treatment especially for patient who suffer from small hypopigmented lesions as this method requires a donor skin of the same size. The cell suspension procedure may be beneficial for larger scars. Moreover demarcation between skin graft and normal skin may exist and when a precise color match is required, particularly in the head, tattooing and chip skin grafting produce a good pigmentation outcome.

Burns caused by electronic vaping devices (e-cigarettes): A new classification proposal based on mechanisms.

Introduction With more than 10 million of daily users, e-cigarettes encountered a great success. But in the past few years, the number of medical reports of injuries caused by the explosion of e-cigarettes has significantly increased. This article aims at reporting our series and reviewing the literature to propose a new classification based on the mechanisms of injuries related to e-cigarettes that can guide non-specialists and specialists in the management of these patients. Method We performed a retrospective review of our institutional burn database from June 2016 to July 2017 for injuries caused by or in the context of using an e-cigarette. The patients' demographics (age, gender), burn injury mechanisms, depth, localization, surface and interventions were described. Results Ten patients suffered from burns related to the use of e-cigarettes. The burns were located at the thigh (80%) and the hand (50%) with a mean surface of 3% of TBSA. Four different mechanisms could be described: Type A: thermal burns with flames due to the phenomenon of "thermal runaway", Type B: blasts lesions secondary to the explosion, Type C: chemical alkali burns caused by spreading of the electrolyte solution and Type D: thermal burns without flames due to overheating. These different mechanisms suggest specific surgical and non-surgical management. Conclusion Management of injuries sustained from e-cigarettes' explosions should be approached from the standpoint of mechanisms. Different mechanisms could be associated and should be considered in specific management.

[Reconstruction of abdo-perineal resection by Taylor flap: About 68 patients]. / Reconstruction par lambeau de Taylor après amputation abdomino-périnéale : à propos de 68 cas.

PURPOSES: Healing after abdomino-perineal resection is often difficult, especially in patients who have undergone radiation therapy. Vaginal reconstruction is also an important issue for the women who undergo this surgery. We describe and analyze here our series of perineal reconstructions with modified Taylor flaps. Between 2010 and 2016, 68 patients (52 women, 16 men) with cancer of the anal canal (53), adenocarcinoma of the lower rectum (9), or other malignant neoplasms of the perineum underwent reconstruction with a rectus abdominis myocutaneous (RAM) flap with an inferior pedicle and an oblique skin paddle. RESULTS: This review of records showed that all patients healed, with a median of 30 days. The reoperation rate was 11.7% including 1 for eventration. The principal causes for delayed healing were scar dehiscence, abscess, and partial necrosis. No flap required removal, however. The mean duration of hospitalization was 23.7 days. CONCLUSION: Modified Taylor flaps substantially improved the reconstruction of defects resulting from abdomino-perineal resection. They enabled complete and rapid healing with low comorbidity.

[Study of satisfaction concerning the navel after abdominal dermolipectomy with transposition: A report of 96 cases]. / Ombilicoplastie en aile de mouette : technique et satisfaction ; à propos de 96 cas.

GOAL OF THE STUDY: The umbilicus has a major role in the aesthetics of the anterior abdominal wall. Many publications deal with abdominal dermolipectomies but few focus on umbilicoplasty. However, these are essential in assessing the aesthetic result. Umbilicoplasty in "aile de mouette" used in our service is reliable and easily reproducible. In this article, we evaluate the satisfaction of patients with abdominal dermolipectomy with this technique of transposition. MATERIALS AND METHOD: In the plastic surgery department of the Saint-Louis Hospital in Paris, we carried out a retrospective study of patients undergoing abdominal dermolipectomy with transposition of the umbilicus, between 1 January 2012 and 31 December 2012. All patients were operated according to our technique of umbilicoplasty: disinsertion of the umbilicus in V, reinsertion of the umbilic in "aile de mouette", a degreasing periumbilical associated with a plication of the umbilical stem. The complications identified in patients medical records and satisfaction were assessed by a telephone questionnaire. RESULTS: Ninety-six patients were included. No patient presented umbilical necrosis. The overall result of umbilical transposition was considered good to excellent for 92.7% of patients. CONCLUSION: Umbilicoplasty in gull wing has many advantages: it is a simple, easily reproducible, reliable technique, the patients of which are for the most part very satisfied.

Pressure guided surgery of compartment syndrome of the limbs in burn patients.

Compartment syndrome is a serious complication of high voltage electrical burns, limb carbonization and deep circular burns with delayed escharotomy. Without treatment, ischemic tissue damage leads to irreversible necrosis. Treatment is emergency surgical decompression. The burned patient is usually not searchable and cannot always be readily examined because of bulky dressings; diagnosis of compartment syndrome is always hard to make. The pressure transducer used in central arterial catheters is easy available. We used it to measure pressure in muscular compartments. We measured compartment pressure three times at different depths in all cases of electrical burn, carbonization and deep circumferential burns with delayed escharotomy. We also took the pressure in the uninjured limb. The pressure assessment device was composed of a blood pressure transducer commonly used in arterial catheters for arterial pressure monitoring with three connecting branches. The first branch was connected to the 'arterial pressure exit' in the monitoring device. The second, an IV tube, was connected to one litre of physiological serum in a pressure bag inflated to 200 mmHg. The third, also an IV tube with a sterile extension cable, was directly connected to an 18G standard straight needle to be inserted in the tissues for which interstitial pressure had to be measured. In patients with thermal burns, we measured pressure before and after escharotomy. Threshold intracompartmental pressure was 35 mmHg. We carried out pressure assessment of all muscular compartments during and at the end of surgery. The pressure transducer provides a pressure value in all muscular compartments with a time of installation and measuring of less than 5 minutes. Sensitivity is measured at +/- 1 mmHg. Operation is simple, non-operator dependent, and accessible to medical and paramedic teams. The pressure transducer allows accurate diagnosis of early or established compartment syndrome. It requires no additional equipment and its application does not delay therapeutic management. Its use helps with fasciotomy decision, especially after escharotomy, guides the surgeon in the exploration of different compartments and verifies the effectiveness of surgery.

Le syndrome de loge est une complication sévère des brûlures électriques de haut voltage, les carbonisations de membres et les brûlures profondes circulaires en attente d'escarrotomie. Sans traitement, les lésions tissulaires ischémiques apparaissent et entrainent des lésions nécrotiques irréversibles. Le traitement est la décompression chirurgicale d'urgence. Le brûlé est généralement in interrogeable et le diagnostic est toujours difficile à établir étant donné les volumineux pansements. Le capteur de pression au moyen de cathéters artériels est facile et nous l'utilisons pour mesurer la pression dans les loges musculaires. Nous mesurons cette pression compartimentale à 3 reprises à des profondeurs différentes, dans tous les cas de brûlures électriques avec carbonisation et brûlures circonférentielles profondes et qui sont en attente d'escarrotomie: nous prenons également la pression au niveau des membres non atteints. L'appareil de mesure est composé d'un capteur de pression sanguine, avec trois connexions: la première est la pression artérielle habituelle, la deuxième est en rapport avec 1 litre de sérum dans une poche gonflée à 200 mm Hg, la troisième est directement en rapport avec une aiguille 18 G pour être insérée au niveau des loges musculaires. Chez les patients porteurs de brûlures thermiques, la pression est prise avant et après l'escarrotomie. Le niveau de pression intra compartimentale est de 35 mm d'Hg. Nous évaluons la pression dans toutes les loges pendant la chirurgie et à la fin de l'intervention. Le capteur permet d'évaluer la pression dans tous les compartiments musculaires en moins de cinq minutes, avec un degré de fiabilité de plus ou moins 1mm Hg. L'opération est simple, non opérateur dépendant et accessible aux médecins et aux paramédicaux. Le capteur de pression permet le diagnostic précoce du syndrome de loge. Il ne nécessite pas un équipement additionnel et son usage ne retarde pas le début de la thérapeutique. Il aide à la décision de fasciotomie, spécialement après escarrotomie, guide le chirurgien dans l'exploration des différentes loges et vérifie l'efficacité de la chirurgie.
