    Treatment of Mallet Finger Deformity with Ring Splint
    (2018-07-01) Hosbay, ZEYNEP; Guneren, ETHEM; HOŞBAY, ZEYNEP; GÜNEREN, ETHEM
    Mallet finger deformity is the loss of active extension on distal interphalangeal joint and possessing hyperextension deformity on PIP joint. Although there are several treatment alternatives for mallet finger deformity, optimal treatment is unclear. In this paper, we discuss Mallet finger deformity caused by blunt injuries in the late term in a 7-year-old patient, who underwent second surgery. We also discuss the results of subsequent physiotherapy program.

    The Multiple Osteotomized Free Iliac Osteocutaneous Flap for Reconstructions of Complex Maxillofacial and Oromandibular Defects
    (2013-09-01T00:00:00Z) KARAALTIN, Mehmet Veli; Canter, Halil Ibrahim; BATIOGLU-KARAALTIN, Aysegul; YOGUN, Fatma Nilay; Guneren, ETHEM; SOENMEZ, Tolga Taha; GÜNEREN, ETHEM
    The vascularized iliac osteocutaneous flap has been used successfully for jaw reconstruction. To obtain a better contour of the reconstructed area in large upper and lower jaw resections, the transferred bone actually needs to be osteotomized. Single closing-wedge osteotomy of the iliac flap for mandibular reconstruction has been previously described. In this article, the modified multiple osteotomized perforator-based versatile free iliac osteocutaneous flap is described. Eleven cases were enrolled. Seven patients had wide anterior mandibular resections due to oral cavity and mandibular tumors; 3 patients had a defect due to explosive injury and 1 patient had complicated orbitomaxillary defect due to blast injury. Skin paddle was based on the perforators. In 8 patients, the bony segment was divided into 3 segments by 2 osteotomies, whereas in 2 patients the bony segment was divided into 4 segments by 3 osteotomies. In 10 cases, the flap was used for anterior mandibular defects, whereas in 1 case the flap was customized to fit an L-shaped defect at the naso-orbito-maxillary region. The overall flap success rate was 100%. No resorption or morbidity related to the osteotomy of the bony segments was observed. The size of perforator skin paddle was 6 to 8 x 15 to 18 cm. Physical and radiologic examinations showed proper bone healing without any additional complications. The modified multiple osteotomized free osteocutaneous iliac flap can provide a safe and versatile bony segment to be arranged and adapted to reconstruct complex mandibular and maxillofacial defects.

    Primary cutaneous carcinosarcoma: The first reported case with peripheral nerve sheath differentiation
    (2014-06-01T00:00:00Z) Yildiz, PELİN; Tosuner, ZEYNEP; Guneren, ETHEM; Demirkesen, Cuyan; YILDIZ, PELİN; TOSUNER, ZEYNEP; GÜNEREN, ETHEM
    Primary cutaneous carcinosarcomas (CS) are extremely rare biphasic tumors mainly located on sun-exposed areas of the body. Two hypotheses-multiclonal (convergence) and monoclonal (divergence)-have been suggested for the evolution of these tumors. According to multiclonal hypothesis two or more stem cells of epithelial and mesenchymal origin give rise to these tumors, while a single totipotential cell differentiate into epithelial and mesenchymal components, either synchronously or metachronously according to monoclonal hypothesis. Cutaneous CSs are subdivided into two distinct groups as epidermal and adnexal CSs, due to their epithelial content. We present an interesting case of cutaneous adnexal CS, showing peripheral nerve sheath differentiation and having the spiradenocarcinoma component derived from spiradenoma. To the best of our knowledge, it is the first reported case of CS with these features in the literature.

    Electrical burns: Highlights from a 5-year retrospective analysis
    (2016-05-01) KURT, Alper; YILDIRIM, Kamil; Yagmur, Caglayan; Kelahmetoglu, OSMAN; ASLAN, Ozan; GUMUS, Murat; Guneren, ETHEM; KELAHMETOĞLU, OSMAN; GÜNEREN, ETHEM
    BACKGROUND: Electrical burns are the third most common cause of burn injuries, after scald and flame burns. In spite of decreasing mortality rates as advancements are made in treatment modalities and medical equipment, significant complications and socioeconomic consequences still accompany electrical burns. Analyzed in the present study were data from patients hospitalized for electrical burns between 2008 and 2012 in the Samsun Training and Research Hospital, the only burn care center in the Black Sea region of Turkey.

    COMPARISON OF THE FLAP SURVIVAL WITH ISCHEMIC PRECONDITIONING ON DIFFERENT PEDICLES UNDER VARIED ISCHEMIC INTERVALS IN A RAT BILATERAL PEDICLED FLAP MODEL
    (2014-02-01) Yildiz, KEMALETTİN; KARSIDAG, Semra; AKCAL, Arzu; YESILOGLU, Nebil; UGURLU, Kemal; OZAGARI, Aysim; Guneren, ETHEM; BAŞ, Lutfu; YILDIZ, KEMALETTİN; GÜNEREN, ETHEM
    The study was undertaken to search whether pedicle selection for ischemic preconditioning (IP) and duration of global ischemia applied after IP influenced efficacy of IP on flap viability in epigastric adipocutaneous island flap with bilateral pedicles in rat model. In total, 159 rats were divided into one control and three (primary, secondary, or bilateral pedicle) IP treatment groups. IP was performed on different pedicles by three cycles of 10 minutes of pedicle clamping and 10 minutes of release. After IP procedure secondary pedicle was ligated in all groups, and flaps were exposed to 0, 1, 2, 4, or 6 hours of global ischemia by clamping primary pedicle. In control groups, after the perfusion of bipedicled flaps for 1 hour, left pedicle was ligated and flaps were exposed to global ischemia as in IP groups. On day 5 post-surgery, tissue samples and topographic measurements were taken. No significant differences in semi-quantitative scorings of polymorphonuclear leukocytes infiltration, chronic inflammation, interstitial edema, neovascularization, VEGF, and CD105 expression levels among groups were found (P > 0.05). Percentages of necrosis were consistently smaller in IP groups compared to controls for the same duration of global ischemia, with exception of the no-ischemia. Area of necrosis was significantly smaller in primary IP group versus secondary IP group in the absence of global ischemia (P 0.05). Thus, IP performed on different pedicles may ameliorate flap survival in a comparable fashion, depending on the duration of global ischemia. Secondary pedicle IP was as effective as primary pedicle IP and may be feasible in free flap transfers. (c) 2013 Wiley Periodicals, Inc. Microsurgery 34:129-135, 2014.
