Article Duchenne Muscular Dystrophy Patients Diagnosed at the Asymptomatic Stage: What Are the Benefits of Early Diagnosis(Turkish Society of Physical Medicine and Rehabilitation, 2024-11-14) Sertpoyraz, Filiz Meryem; Tanigor, Goksel; Baydan, Figen; Kale, Murat Yildirim; Tanigoer, GoekselObjectives: This study aimed to demonstrate whether a diagnosis given at the asymptomatic stage of patients with DMD can affect the clinical outcomes and to define the clinical characteristics of the patients. Patients and methods: The cross-sectional study was conducted with 136 male patients (mean age: 8.8±3.7 years; range, 3 to 17 years) with DMD between March 2022 and February 2023. The patients were diagnosed through clinical presentation, pathology studies, and genetic testing. The demographic, clinical, and the laboratory data of the patients were recorded. The patients were evaluated in two groups: those diagnosed at the asymptomatic stage due to elevated creatine kinase (CK) and those diagnosed due to clinical symptoms. Patients were further stratified according to their age groups: those younger than 10 years and those aged 10 years or older. Hand grip, quadriceps muscle strength, and Vignos and Brooke motor functional assessment scales of the two groups were compared. Results: In patients who were diagnosed with CK levels, CK elevation was significantly more common than other findings. When the age at diagnosis was evaluated, the age at diagnosis in those diagnosed with CK levels was statistically significantly lower than in those diagnosed with clinical findings. No significant difference was detected in clinical findings between the groups under the age of 10 years. Among patients aged 10 years or older, hand muscle strength, quadriceps muscle strength, and Vignos and Brooke motor function scale scores were significantly better in those diagnosed with CK levels compared to those diagnosed with clinical findings. Conclusion: This study shows that early diagnosis in the preclinical period, which enables earlier medical treatment and rehabilitation, may have a positive effect on motor functions and the course of the disease.Article Citation - WoS: 2Citation - Scopus: 2A New Scoring System for the Evaluation of Ibrutinib-Associated Arrhythmias in Chronic Lymphocytic Leukemia: the ACEF Score(Turkish Society of Hematology, 2024-05-30) Ugur, Mehmet Can; Bilgir, Oktay; Dogdus, Mustafa; Koyuncu, İlhan; Senoz, Oktay; Koyun, Emin; Koyuncu, BetulAmaç: Kardiyak dokuda Bruton tirozin kinaz inhibisyonu, stres sırasında dokunun korunmasından sorumlu olan PI3K-AKT sinyal yolunun inhibisyonuna neden olur. Bu nedenle aritmi riskinde bir artış vardır. Bu çalışma, yaş, kreatinin ve ejeksiyon fraksiyonu komponentlerini temel alan ve basit bir puanlama sistemi olan Yaş-Kreatinin-Ejeksiyon Fraksiyonu (ACEF) skoru ile bu riskin tahmin edilebilmesini araştırmaktadır. Gereç ve Yöntemler: Kronik lenfositik lösemi (KLL) tanısı alan ve en az 1 yıldır ibrutinib tedavisi alan hastalar ekokardiyografi ve Holter elektrokardiyografi ile değerlendirildi ve sonuçlar tedavi almayan KLL hastalarından oluşan kontrol grubuyla karşılaştırıldı. ACEF skoru, yaş/sol ventriküler ejeksiyon fraksiyonu+1 (kreatinin >2,0 mg/dL ise) formülüyle hesaplandı. Bulgular: Hastaların aritmi gelişimi değerlendirildiğinde paroksismal atriyal fibrilasyon (PAF) dışındaki aritmi türleri açısından kontrol ve ibrutinib grupları arasında istatistiksel olarak anlamlı bir fark bulunmadı. PAF, ibrutinib kullanmayanlar ile kullananlar arasında %8’e karşı %22 (p=0,042) oranında meydana gelmekteydi. İbrutinib kullanan hastalarda ACEF skorunun >1,21 olması, PAF gelişimini %77 duyarlılık ve %75 özgüllükle öngörmekteydi (eğri altındaki alan: 0,830, %95 güven aralığı: 0,698-0,962, p<0,001). Sonuç: ACEF skoru, KLL tanısı alan ve ibrutinib başlanması planlanan hastalarda PAF gelişimini öngören bir risk skoru olarak kullanılabilir.Article Citation - WoS: 7Citation - Scopus: 8Solid Pseudopapillary Neoplasms of the Pancreas: Case Series With a Review of the Literature(Aves, 2020-12-15) Uguz, Alper; Unalp, Omer Vedat; Akpinar, Goksever; Karaca, Can Avni; Oruc, Nevin; Nart, Deniz; Yilmaz, Funda; Aydın, Ahmet; Coker, AhmetBackground/Aims: The solid pseudopapillary neoplasms are quite rare tumors of the pancreas, comprising roughly 1-2% of all pancreatic neoplasms. It has a low malignant potential and usually affects young females. Despite increasing number of articles in the last decade, there is still debate on the pathogenesis, malignant potential and optimal surgical strategy for the solid pseudopapillary neoplasms. Materials and Methods: Medical recordings of 326 patients who were operated due to pancreatic mass were retrospectively analyzed. Patient demographics, presenting symptoms, surgical and pathologic characteristics of the tumor, postsurgical course, long-term survival, and other relevant data were extracted from patients' charts. Results: Majority of the patients were female in consistency with the classic data in the literature. All the patients underwent curative intent resections. Tumors were commonly localized in the tail of the pancreas making distal pancreatectomy the most commonly performed surgical procedure. Mean tumor diameter was 5.8 centimeters with tumor sizes ranging from 1 to 19 cm. Conclusion: The solid pseudopapillary neoplasms of the pancreas is a rare tumor with low malignant potential, which is more common in females of reproductive age, with abdominal pain being their most common presentation. The short-term outcomes in patients following surgical R0 resection are excellent. However, proximal placement of the tumor and female gender may have slightly worse prognosis. We hope that our findings from a series of patients represent a contribution to the existing literature on SPN, and authors declare their willingness to provide further details for future meta-analyses.Article Citation - WoS: 3Citation - Scopus: 6Effects of Bevacizumab Administration on the Hypoxia- Induced Pulmonary Hypertension Rat Model(Tubitak Scientific & Technical Research Council Turkey, 2021-10-21) Demir, Canan; Karaman, Meral; Ucan, Eyup Sabri; Gokmen, Ali Necati; Gurel, Duygu; Coker, Sadiye Canan; Adali, Yasemen; Yilmaz, Osman; Gokmen, Necati; Coker, CananBackground/aim: Bevacizumab is a chemotherapeutic drug, which selectively binds to vascular endothelial growth factor (VEGF) and mainly inhibits angiogenesis and neovascularization. We aimed to study the possible effects of bevacizumab on right ventricular pressure (RVP), right ventricular hypertrophy, and VEGF, in hypoxia -induced pulmonary hypertension (PH) rat model. Materials and methods: 24 adult Wistar Albino rats were randomly divided into four groups: control group -saline; Bevacizumab Group; PH Group; PH + Bevacizumab Group. In hypoxia -induced model, 10% oxygen and 90% nitrogen were applied in a plexiglas box for eight days to PH Group and PH + Bevacizumab Group. On day eight, RVPs were measured directly from the heart, and then animals were sacrificed. Heart and lung tissues were examined, and Fulton index was measured. Results: RVP, Fulton index, and tissue VEGF scores were significantly lower in PH + Bevacizumab group than PH group: median (ranges), RVP, mmHg, 37.8 (33.0-39.0) and 32.3 (28.0-35.0), p: 0.01; Fulton index: 0.30 (0.29-0.33) and 0.25 (0.24-0.26), p: 0.003; tissue VEGF scores: 5.1 (4.8-5.3) and 4.0 (3.8 4.1), p: 0.004, respectively. Conclusion: Bevacizumab, which is indeed an antineoplastic agent, might have a favorable effect on hypoxia -induced pulmonary hypertension.
