Publication Metadata only A Basic Algorithmic Surgical Approach for Nicolau Syndrome(2020-04-01T00:00:00Z) Yeniocak, Ali; Güneren, Ethem; Özkan, Mustafa; Temel, Metin; Kelahmetoğlu, Osman; YENİOCAK, ALİ; GÜNEREN, ETHEM; KELAHMETOĞLU, OSMANBackground: Nicolau syndrome (NS) is a rare complication that develops after the administration of intramuscular diclofenac sodium. The etiology and surgical treatments of 11 patients with NS were evaluated and studies in the literature were examined. The aim of this study was to compose a basic algorithm for surgical approaches to treat NS. Materials and methods: Eleven patients were evaluated for NS between December 2013 and January 2018. Two patients did not accept treatment, and nine patients underwent surgical debridement of necrotic tissues. The tissue defects of five patients were closed with a fasciocutaneous flap and, in four patients, the defects were repaired primarily. Results: No complications, such as wound infection, wound dehiscence, seroma, or flap necrosis, were encountered. Of the seven patients who received concurrent antibiotic therapy, no patient had any problems at their follow-up (2-30 months). The results were satisfactory from an aesthetic and functional point of view. Conclusion: NS was more frequent in women with a high body mass index and high fat in gluteal regions. We considered that any kind of medication could lead to NS. Different methods are discussed for treatment.Publication Metadata only The Use of Intramedullar Vascularized Fibular Flap and Recycling of Resected Bone for Long Bone Reconstruction Following Sarcoma Resection(2019-06-12T00:00:00Z) Kelahmetoğlu, Osman; Gürkan, Volkan; Güneren, Ethem; KELAHMETOĞLU, OSMAN; GÜRKAN, VOLKAN; GÜNEREN, ETHEMPublication Metadata only Early Suspicion of Heparin-Induced Thrombocytopenia for Successful Free Flap Salvage: Reports of Two Cases(2020-06-01T00:00:00Z) Mehdizade, Turan; Kelahmetoğlu, Osman; Gürkan, Volkan; Çetin, Güven; Güneren, Ethem; KELAHMETOĞLU, OSMAN; GÜRKAN, VOLKAN; ÇETİN, GÜVEN; GÜNEREN, ETHEMHeparin-induced thrombocytopenia (HIT) is an underestimated complication of heparin treatment. Flap loss and related morbidity (even mortality) are caused by occlusion of the capillary vessels by a highly immunogenic complex formed by adherence of antiheparin antibodies to platelet factor 4. Early suspicion and effective treatment of HIT developing in two free flaps are described. We report on the management of two patients with HIT. Both patients were treated successfully by early suspicion and hematology consultation. Heparin products were discontinued; the patients were switched to a nonheparin anticoagulant. We emphasize the importance of early diagnosis, hematologist assessment, and a change to a nonheparin anticoagulant to prevent flap failure and possibly the catastrophic consequences of such failure.Publication Open Access Boneless Maxillary Reconstruction(2020-01-01T00:00:00Z) Kelahmetoğlu, Osman; Güneren, Ethem; Kuzu, Ismail Melih; Yıldız, Kemalettin; KELAHMETOĞLU, OSMAN; GÜNEREN, ETHEM; YILDIZ, KEMALETTİNObjective: Although the midface is supported by maxillary bone, reconstruction of maxillary bony defects does not always require osseous reconstruction. A series of maxillary facial defects of moderate to severe sizes (Brown and Shaw 4-6) uniformly reconstructed with myocutaneous free flaps is presented. Methods: Retrospective analysis was done for consecutive 10 cases between 2013-18. Seven of the cases had defects caused by oncological resection and 3 defects caused by trauma. Free vertically oriented rectus abdominis (fVRAM) flap was used to reconstruct these defects. The mean age of patients was 42.9 years (range=20-71 years). All flaps survived and 2 flaps had small skin island problems. Rapid recovery, low morbidity, acceptable oral competency, and satisfactory cosmetic appearance were obtained with the reconstruction using fVRAM flaps. Conclusion: According to our limited experience, acceptable reconstruction of extensive maxillary defects can be done with using only soft tissue flap, which is versatile and safe.Publication Metadata only Lower pole reconstruction in a post-burn breast using an anterolateral thigh flap: A case report(2019-01-01T00:00:00Z) Kelahmetoğlu, Osman; KELAHMETOĞLU, OSMANPublication Metadata only The Recontouring of Soft Tissue Defects Around Foot and Ankle with Free ALT Perforator Flaps(2019-06-12T00:00:00Z) Kelahmetoğlu, Osman; KELAHMETOĞLU, OSMANPublication Metadata only The effects of a single high-dose injection of vitamin-D on healing of condylar fractures in osteoporotic rats(2019-01-01T00:00:00Z) Mercan, Ugur; Kelahmetoğlu, Osman; KELAHMETOĞLU, OSMANPublication Open Access The Effect of Vitamin D3 on Skeletal Muscle in Rat after Ischemia Reperfusion Injury: Preliminary Report(2020-07-01T00:00:00Z) Kelahmetoğlu, Osman; Tok, Enis Olgu; Özer, Ömer Faruk; Yeniocak, Ali; Yağmur, Çağlayan; Eşrefoğlu, Mukaddes; Koçyiğit, Abdürrahim; Yıldız, Kemalettin; Güneren, Ethem; KELAHMETOĞLU, OSMAN; ÖZER, ÖMER FARUK; YENİOCAK, ALİ; EŞREFOĞLU, MUKADDES; KOÇYİĞİT, ABDÜRRAHİM; YILDIZ, KEMALETTİN; GÜNEREN, ETHEMObjective: Vitamin D is a vitamin that has gained popularity in recent years and has an anti-inflammatory and immunmodular effect. In the literature review we conducted, there was no study investigating the effect of vitamin D to prevent ischemia reperfusion (I/R) injury in skeletal muscle. The aim of this study was to investigate the effect of vitamin D on skeletal muscle in I/R injury. Methods: Six rats were used in each group including ischemia group (group I) and experimental group (group D given vitamin D). In the histopathological examination, inflammation and apoptosis levels were studied in gastrocnemius muscle. In biochemical analysis, total oxidative stress and total antioxidant and catalase levels were evaluated in anterior tibialis muscle. Results: The number of apoptotic cells in group D were found significantly lower than group I. In the terms of total antioxidants and catalase levels, there were significant difference between group D and group I. Conclusion: Our results support the hypothesis that vitamin D is an agent that can be used to prevent I/R injury.
