Hypertrophic scars and Dupuytren's disease are characterized by the presence of modified fibroblasts or myofibroblasts which allegedly responsible for tissue retraction excessive connective production. γ-Interferon, a cytokine produced T-helper lymphocytes, has been shown to decrease fibroblast replication, α-smooth-muscle actin (the isoform characterizing myofibroblasts) expression, collagen We have investigated in an open pilot study possibility that intralesional injections γ-interferon...
Noma is a gangrenous stomatitis affecting children from developing countries. It may leave dreadful mutilations around the mouth, with amputation of lips, cheek, nose, lids, maxilla, palate, or mandibula. Reconstruction should take into account size defect, presence trismus constriction mandible, age child, and child's general condition. During last 3 years, eight patients were treated at Unit Plastic Reconstructive Surgery Hôpital Cantonal Universitaire. Except in one case, tracheostomy was...
BackgroundNoma is a poorly studied disease that leads to severe facial tissue destruction in children developing countries, but the cause remains unknown. We aimed identify epidemiological and microbiological risk factors associated with noma disease.MethodsWe did prospective, matched, case-control study Niger between Aug 1, 2001, Oct 31, 2006, younger than 12 years assess for acute noma. All cases were included four controls each case matched by age home village. Epidemiological clinical...

A reversed fasciosubcutaneous tissue flap in the leg is described. This distally based vascularized by perforating cutaneous branches of peroneal and tibialis posterior arteries. It must carry all its subcutaneous tissue. study on vascularization reveals predominance vascular network this layer with regard to dermal or fascial plane. The at donor site sufficient let skin survive without underlying support. can reach malleolar heel region. advantages technique are (1) easy dissection, (2)...
The galea aponeurotica has been used by various surgeons either as a supporting sheet or blood carrier for bringing flaps to areas of the face. In this study, we first reviewed anatomy scalp vascularization means cadaver injections. arteries and veins are mainly located in numerous anastomotic vessels present over vertex. physiology studied percutaneous PO2 registration after occlusion tourniquet placed around head. superficial temporal have found be most important designing On basis these...
We report a cohort of 148 African children operated on between 1985 and 2000 for noma sequelae. A total 440 operations were performed. Lesions included mouth constriction in 70 cases, severe bone destruction 69 cases. large proportion was transferred to Switzerland surgical treatment, whereas the others local hospitals Africa. Vascularized calvarium flap mostly used reconstruction (n = 36). Pedicled latissimus dorsi myocutaneous preferred strategy cheek 40). Expanded frontal nasal 18),...
Sensibility and sensory reinnervation were investigated in 19 patients who underwent, after mastectomy, a breast reconstruction using myocutaneous flaps. A comparative study of the flaps has been performed either surgery with latissimus dorsi flap prosthesis or simple double pedicle transverse rectus abdominal flap. Ten 9 tested. The tests included stimulation touch, pressure, pin prick, temperature. also interviewed regarding their impressions, subjective sensibility. These results show...
The serratus anterior flap is commonly used without its cutaneous component and covered with a skin graft. authors have successfully the free along paddle found it to be valuable for reconstruction of face.Fresh cadaveric dissections arteriography were performed identify perforator vessels overlying muscle. Clinically, transfer musculocutaneous face was carried out in 27 patients, mostly severe noma (infection) sequelae.Anatomical dissection revealed no directly communicating vascular...
ABSTRACT We describe a new animal model designed to assess the impact of ischemia on wound healing. Eight patterns arterial lesion in limb were first tested 24 Wistar rats. Resection external iliac artery down femoral at level knee was chosen as reference and performed left 45 rats; right used control. Skin wounds measuring 1.2 × 0.8 cm created both feet. Ischemia assessed by blood flow measurement, which decreases dramatically ischemic limb. A significant delay closure with decrease...
It has recently been shown that during the healing of an open wound, apoptosis mediates decrease in cellularity transition between granulation tissue and scar. Because reduced contraction a number fibroblastic cells have described wounds covered with successful skin graft, we hypothesized could be responsible for these phenomena. Using situ labeling fragmented DNA, immunohistochemistry alpha-smooth muscle actin, electron microscopy, studied rats evolution 10-day-old wound total flap...
It is surprising that in a recently published symposium on reconstruction of the nose, not one article mentioned tempororetroauricular flap described by Washio. In our experience, this method very useful tool for difficult nasal reconstructions young individuals. safe procedure (not to be compared with free flaps same region), and it provides thin skin cartilage can adapted different types defect. Exceptionally, may provide sufficient amount tissue total nose reconstruction. As most other...
Acquired large nasal defects are much more common in adulthood than childhood because of the frequency skin tumors after a certain age. However, from their experience treating number children with sequelae noma and burns, authors have collected series 17 total 12 partial reconstructions aged 1 to 15 years. After reviewing various methods used for recreating lining, support, cover whole series, three cases reported detail. A 1-year-old patient received tempororetroauricular flap amputation...
