Öğe Çocuklardaki Monteggia eşdeğer lezyonlarında tedavi sonuçları(2008) Güven, Melih; Eren, Abdullah; Kadıoğlu, Barış; Yavuz, Umut; Kılınçoğlu, Volkan; Özkan, KorhanAmaç: Monteggia eşdeğer lezyonlu çocuklarda konservatif ve cerrahi tedavi sonuçları değerlendirildi. Çalışma planı: Çalışmaya, Monteggia eşdeğer kırıklıçıkığı nedeniyle tedavi edilen 13 çocuk hasta (3 kız, 10 erkek; ort. yaş 8; dağılım 4-13) alındı. Yedi hastada (%53.9) Bado tip 1, altı hastada (%46.2) ise tip 3 eşdeğer lezyon vardı. Tip 3 eşdeğer lezyonlu hastaların ikisinde aynı zamanda humerus lateral kondil kırığı saptandı. Bir hastada (%7.7) radial sinir felci vardı. Açık kırıklı-çıkık nedeniyle acil debridman ve irigasyon uygulanan bir hasta dışında, tüm hastalarda öncelikle kapalı redüksiyon denendi. Sekiz hastada (%61.5) konservatif tedaviyle yeterli redüksiyon sağlandı. Dört hastada (%30.8) redüksiyon sağlanamaması nedeniyle, yaralanmadan sonra ilk 24 saat içinde cerrahi girişim uygulandı. Fonksiyonel değerlendirme Reckling evrelemesine göre yapıldı. Ortalama takip süresi 4.1 yıl (dağılım 2-7 yıl) idi. Sonuçlar: Hiçbir olguda kaynamama gözlenmedi. Konservatif tedavi gören hastaların hiçbirinde radius başında redüksiyon kaybıyla karşılaşılmadı ve dirsek hareketlerinde kısıtlılık gözlenmedi. Bir hastada (%7.7) dirsekte 5° kubitus varus deformitesi, radyografik olarak ise ulnada kırık hattında 20° posteriora açılanma saptandı. Konservatif tedavi gören hastaların hepsinde fonksiyonel sonuçlar iyi idi. Cerrahi tedavi uygulanan dört hastada fonksiyonel sonuçlar iyi iken, açık kırıklı-çıkığı olan olguda kötü sonuç alındı. Bir hastada 10° supinasyon kısıtlılığı vardı. Dirsek eklemi hareket genişliğinde fleksiyon ve ekstansiyon kısıtlılığı yoktu. Başvuru anında radial sinir felci olan bu hastada sinir lezyonu ameliyat sonrası üçüncü ayda düzeldi. Çıkarımlar: Çocuklardaki Monteggia eşdeğer lezyonlarda öncelikli tedavi kapalı redüksiyondur. Redüksiyon sağlanamaması durumunda cerrahi tedavi gündeme gelir.Öğe The Effect of Talaromyces funiculosus ST976 Isolated from Pistacia vera Rhizosphere on Phosphorus Solubility in Soil Samples with Different Physicochemical Properties(2022) Türkölmez, Şahimerdan; Eren, Abdullah; Özer, Göksel; Derviş, SibelIn this study, a total of 78 Talaromyces isolates were isolated from the pistachio (Pistacia vera L.) rhizosphere heavily infested with Neoscytalidium spp. The identification studies of the four representative isolates based on morphological and molecular methods showed that all isolates were T. funiculosus. The 575 bp long sequence of the internal transcribed spacer region of T. funiculosus isolate ST976, selected as a representative of the isolates, was deposited in GenBank under accession no. MW130842. The Maximum Likelihood tree clustered the ST976 isolate with reference T. funiculosus isolates derived from the GenBank nucleotide database. The phosphorus dissolution ability of ST976 isolate was determined by an experiment using six soil samples collected from agricultural lands in various locations of Şanlıurfa province. The pH of the soil samples taken varied between 7.21 and 7.88. As a result of the analysis performed with the addition of the isolate ST976 applied to soil samples with different soil structures (Clay and Clay-Loam), it was determined that the isolate ST976 dissolved 109–311% more phosphorus than the control sample. The study is one of the first studies proving the ability of T. funiculosus isolate ST976 to dissolve phosphorus without any additives to soil solution was determined.Öğe A new radiographic measurement method for evaluation of tibial torsion: a pilot study in adults(Lippincott Williams & Wilkins, 2009) Güven, Melih; Akman, Budak; Ünay, Koray; Özturan, Engin Kutay; Çakıcı, Hüsamettin; Eren, AbdullahComputed tomography (CT) frequently is used to determine torsional abnormalities. However, its use in clinical practice may be limited. We present a new method for measuring tibial torsion using conventional radiographs. We compared the method with several clinical methods and with CT measurement in 44 lower extremities of 25 subjects. The radiographic method agreed well with all of the clinical methods, and this agreement was better than agreement between CT and clinical examination. The best agreement was between thigh-foot angle and the radiographic method. The proposed radiographic measurement is a practical method for evaluation of tibial torsion in outpatient clinics without the need for specialized equipment. Level of Evidence: Level II, diagnostic study. See the Guidelines for Authors for a complete description of levels of evidence.Öğe The results of treatment in pediatric Monteggia equivalent lesions(Turkish Assoc Orthopaedics Traumatology, 2008) Guven, Melih; Eren, Abdullah; Kadioglu, Baris; Yavuz, Umut; Kilincoglu, Volkan; Ozkan, KorhanObjectives: We evaluated the results of conservative and surgical treatment of pediatric Monteggia equivalent lesions. Methods: The study included 13 children (3 females, 10 males; mean age 8 years; range 4 to 13 years) who underwent treatment for Monteggia equivalent lesions. Seven patients (53.9%) had Bado type I and six patients (46.2%) had type 3 equivalent lesions. Two patients with type 3 equivalent lesions also had a lateral humeral condyle fracture. On presentation, one patient (7.7%) had radial nerve palsy. Primarily, closed reduction was attempted in all the patients except for one patient who underwent urgent debridement and irrigation for an open fracture-dislocation. Reduction was successful in eight patients (61.5%). Upon failure of closed reduction, four patients (30.8%) underwent surgery within the first 24 hours of injury. Functional assessment was made according to the Reckling's criteria. The mean follow-up period was 4.1 years (range 2 to 7 years). Results: None of the patients had nonunion. Conservative treatment did not result in loss of reduction of the radius head or limitation in the range of motion of the elbow joint. Except for the patient with an open fracture-dislocation leading to a poor functional result, the results were good in all the patients receiving conservative or surgical treatment. One patient (7.7%) treated conservatively developed cubitus varus (5 degrees) and posterior angulation (20 degrees) of the ulnar fracture line. One patient treated surgically had limitation of supination (10 degrees) without limitation of flexion or extension of the elbow joint. Accompanying radial nerve palsy in this patient disappeared in the postoperative third month. Conclusion: Closed reduction is the first choice of treatment in pediatric Monteggia equivalent lesions. Surgical treatment becomes necessary if closed reduction fails.
