    (Sage Publications Ltd, 2024) Ozdemir, Faruk; Ayanoglu, Tacettin; Dagistan, Emine; Kalaycioglu, Oya; Celik, Ilhan; Kalfaoglu, Melike Elif; Kanatli, Ulunay
    Background Subacromial impingement syndrome is one of the most common causes of painful shoulder in the middle-aged and elderly population. Coracoacromial ligament (CAL) degeneration is a well-known indicator for subacromial impingement. Purpose To examine the relationship between CAL thickness on preoperative magnetic resonance imaging (MRI), arthroscopic CAL degeneration and types of rotator cuff tears. Material and Methods Video records of patients who underwent arthroscopic shoulder surgery between 2015 and 2021 were retrospectively scanned through the hospital information record system. In total, 560 patients were included in this study. Video records of the surgery were used to evaluate the grade of coracoacromial ligament degeneration and the type of cuff tear. Preoperative MRI was used to measure CAL thickness, acromiohumeral distance, critical shoulder angle, acromial index, and acromion angulation. Results Significant differences were observed between grades of CAL degeneration in terms of CAL thickness (P < 0.001). As CAL degeneration increases, the mean of CAL thickness decreases. According to the results of post-hoc analysis, the mean CAL thickness of normal patients was significantly higher than those of patients with full-thickness tears (P = 0.024) and massive tears (P <0.001). Patients with articular-side, bursal-side, and full-thickness tears had significantly higher CAL thickness averages than patients with massive tears. Conclusion This study showed that the CAL thickness decreases on MRI as arthroscopic CAL degeneration increases. High-grade CAL degeneration and therefore subacromial impingement syndrome can be predicted by looking at the CAL thickness in MRI, which is a non-invasive method.

    Changes in the size of breast lesions during menstrual cycle observed by ultrasound: An initial study
    (Scientific Publishers of India, 2017) Dagistan, Emine; Canan, Arzu; Halicioglu, Siddika; Cosgun, Zeliha; Gurel, Safiye
    Purpose: We aimed to evaluate changes in size of breast lesions during menstrual phases. Material and methods: In this prospective study, 46 women aged 18-35 years old who were referred to our radiology clinic for breast sonography and had cystic or solid breast lesions larger than 5 mm were enrolled to the study. Breast ultrasound (US) was performed at two different times; one within 5 days before and one within 5 days after menstrual bleeding. Anteroposterior and transverse length of the lesions were measured. Results: In total, 145 breast lesions were detected by US. Of these lesions, 6 were visualized in premenstrual phase but were not observed in postmenstrual phase. 6 lesions different were not visualized in premenstrual, but were detected in postmenstrual phase. One hundred and twenty-three lesions were visualized by US both in luteal and follicular phases. Conclusions: Timing of breast US might cause false results and unnecessary further investigations. Therefore, we suggest that breast US in women should be performed in follicular phase of the menstrual cycle. © 2017, Scientific Publishers of India. All Rights Reserved.

    Extralobar Pulmonary Sequestration in a Neonate
    (Aves, 2014) Ozturk, Hulya; Goksugur, Sevil Bilir; Dagistan, Emine; Yilmaz, Fahri; Ozturk, Hayrettin
    Congenital pulmonary sequestration (CPS) is a type of thoracic malformation that may be represented as a solid or cystic mass composed of nonfunctioning primitive tissue. It does not interact with the tracheobronchial tree and has unusual systemic blood supply. Various congenital malformations may be presented with CPS. More than one-half of CPS cases are diagnosed in later childhood or even in adulthood. Neonates and infants are usually asymptomatic, and they are usually diagnosed due to the presence of other congenital anomalies. Here, we report a 5-day-old neonate who was admitted to our clinic with respiratory distress. CPS was diagnosed without any other malformation.

    Factors Influencing the Duration of Urine Leakage following Percutaneous Nephrolithotomy
    (Hindawi Ltd, 2014) Uyeturk, Ugur; Gucuk, Adnan; Kemahli, Eray; Dagistan, Emine; Yildiz, Mevlut; Yilmaz, Burak; Metin, Ahmet
    Purpose. The duration of urine leakage following the removal of the nephrostomy tube after percutaneous nephrolithotomy (PCNL) shows significant variations depending on the techniques used. We aimed to assess the factors likely to influence the duration of urine leakage. Material and Methods. In total, 103 patients who underwent PCNL were reviewed retrospectively. DUL was evaluated regarding patient characteristics, thickness of the access line, presence of hydronephrosis, and residual stones. Results. DUL was significantly prolonged in accordance with a decrease in the thickness of parenchyma tissue (R = -0.716, P < 0.001). DUL was prolonged as the degree of hydronephrosis (R = 0.526, P < 0.001) and the number of patients with residual stones (R = 0.273, P = 0.005) increased. Median DUL was significantly longer in patients with residual stones than those without residual stones (P = 0.002). In the receiving operating curve analysis, the optimum cut-off value of parenchymal thickness for hospitalization <= 12 h was 17.2mm (sensitivity, 90.2%; specificity, 69.4%; P = 0.001). Conclusions. We found that parenchymal thickness of the access line, hydronephrosis, and residual stones were the most influential factors determining DUL following PCNL, respectively.

    Kyphoplasty for osteoporotic fractures: Experience of a single center
    (Ondokuz Mayis Universitesi, 2018) Dagistan, Yasar; Dagistan, Emine; Gezici, Ali Rıza; Sari, Kutlu; Aktas, Gulali
    Osteoporosis increases the risk of spontaneous fractures of skeleton by enhancing the microstructure of the bones. Kyphoplasty is preferred for decreasing the pain and disability in treatment of spinal fractures. We aimed to report our clinical experience in kyphoplasty for spinal fracture treatment and to express a brief literature review. We performed balloon kyphoplasty in 14 patients with osteoporotic spinal fractures between January 2012 and July 2015. Nine of the patients were women and 5 were men. Age of the patients ranged between 59 to 81 years. We think that spinal fractures should be initially treated with conventional methods, however, kyphoplasty should be done without a delay because it is very effective in pain and other complications of the fracture and a relatively safer method than other interventions. © 2018 OMU

    Lumbar Microdiscectomy Under Spinal and General Anesthesia: A Comparative Study
    (Turkish Neurosurgical Soc, 2015) Dagistan, Yasar; Okmen, Korgun; Dagistan, Emine; Guler, Ali; Ozkan, Nezih
    AIM:To compare the safety and efficacy of spinal anesthesia (SA) in patients undergoing lumbar microdiscectomy (LM). MATERIAL and METHODS: We evaluated 180 patients who underwent LM between 1 January 2012 and 5 July 2013. Demographic, clinical, laboratory, and pre-, intra-, and postoperative information was determined from the patients' medical records. RESULTS: Total anesthetic times were longer in the general anesthesia (GA) group. There was less bleeding at the surgical site in the SA group. Intraoperative blood pressure was significantly also lower in the SA group. Meanwhile, tachycardia was significantly higher in the GA group. The analgesic requirement in post-anesthesia care unit (PACU) was higher in the general anesthesia group. At PACU admission, analgesic requirement, heart rate, and the mean arterial pressure were higher in the GA group. Postoperative nausea and vomiting was more frequent among patients recovering in general anesthesia group. SA patients had an increased incidence of urinary retention compared with GA patients. Pulmonary complications requiring specific treatment were insignificantly higher among GA patients. CONCLUSION: In patients who undergo lumbar disc surgery, SA is a good alternative for experienced surgeons because of a more comfortable healing process.

    Volumetric segmentation analysis of the levator ani muscle using magnetic resonance imaging in pelvic floor function assessment
    (Turkish Soc Radiology, 2024) Yasar, Aysenur Buz; Yuzok, Ruveyde Begum; Dagistan, Emine
    PURPOSE In this case-control study, we aimed to evaluate how muscle volume affects pelvic floor function by analyzing the levator ani muscle (LAM) using volumetric segmentation in addition to standard magnetic resonance (MR) defecography assessments. METHODS We enrolled 85 patients with varying degrees of pelvic floor dysfunction (PFD) and 85 age- and gender-matched controls in this retrospective study. All patients had MR defecography images, while all controls had pelvic MR images obtained for other reasons. Group comparisons were performed using independent samples t-tests and Mann-Whitney U tests. The receiver operating curve (ROC) was constructed to establish a cut-off value for a normal LAM volume. Interrater reliability was assessed by calculating the intraclass correlation coefficient. A P value of less than 0.05 was considered statistically significant. RESULTS Volumetric measurements revealed that the control group had higher LAM volumes, and the ROC curve analysis indicated a cut-off value of 38934.3 mm 3 with a sensitivity of 0.812 and specificity of 0.8 for PFD assessment using LAM volumetric measurement. Gender did not significantly affect LAM volume in the control group. CONCLUSION Alongside the useful structural and functional information acquired from MR defecography images, volumetric analysis, and three-dimensional reconstructions of LAM may help to improve the accuracy of the diagnosis.
