Publication Radiation exposure in the neonatal intensive care unit in newborns and staff(Thieme Medical Publ Inc, 2021-07-28) Çakır, Salih Çağrı; Dorum, Bayram Ali; Köksal, Nilgün; Özkan, Hilal; Yazıcı, Zeynep; Parlak, Müfit; Gülleroğlu, Nadide Başak; ÇAKIR, SALİH ÇAĞRI; Dorum, Bayram Ali; Köksal, Nilgün; ÖZKAN, HİLAL; YAZICI, ZEYNEP; PARLAK, MÜFİT; Gülleroğlu, Nadide Başak; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediat Bölümü; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Bölümü; 0000-0001-5761-4757; 0000-0002-2823-8454; HJZ-4508-2023; AEZ-2469-2022; A-5375-2017; A-5375-2017; CZV-1969-2022; IGT-7005-2023; AAI-2303-2021; AAG-8521-2021; EZQ-1350-2022Objective Portable X-rays remain one of the most frequently used diagnostic procedures in neonatal intensive care units (NICU). Premature infants are more sensitive to radiation-induced harmful effects. Dangers from diagnostic radiation can occur with stochastic effects. We aimed to determine the radiation exposure in premature infants and staff and determine the scattering during X-ray examinations in the NICU. Study Design In this prospective study, dosimeters were placed on premature infants who were <= 1,250 g at birth and <= 30 weeks of gestational age who stayed in the NICU for at least 4 weeks. The doses were measured at each X-ray examination during their stay. The measurements of the nurses and the doctors in the NICU were also performed with dosimeters over the 1-month period. Other dosimeters were placed in certain areas outside the incubator and the results were obtained after 1 month. Results The mean radiation exposure of the 10 premature infants, monitored with dosimeters, was 3.65 +/- 2.44 mGy. The mean skin dose of the six staff was 0.087 +/- 0.0998 mSV. The mean scattered dose was 67.9 +/- 26.5 mu Gy. Conclusion Relatively high exposures were observed in 90% of the patients and two staff. The radiation exposure levels of premature infants and staff may need to be monitored continuously.Publication Horseshoe lung associated with scimitar syndrome(Bmj Publishing Group, 2019-08-01) Gönen, Korcan Aysun; Canıtez, Yakup; CANITEZ, YAKUP; Bostan, Özlem Mehtap; BOSTAN, ÖZLEM MEHTAP; Yazıcı, Zeynep; YAZICI, ZEYNEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Anabilim Dalı.; 0000-0001-7707-2174; AAH-1789-2021Horseshoe lung is a rare congenital anomaly and mostly accompanied by scimitar syndrome. Most aspects of this complex anomaly can be demonstrated via multidetector CT (MDCT). We present two baby girls who had horseshoe lung associated with right lung hypoplasia and scimitar vein. The chest roentgenograms showed displacement of the heart and mediastinum to the right with smaller right lung. Echocardiography revealed dextroposition, secundum atrial septal defect and bilateral slight peripheral pulmonary stenosis in the first case and dextroposition, severe pulmonary hypertension, secundum atrial septal defect and tricuspid regurgitation in the other one. On thoracic MDCT, the right lung and pulmonary artery were hypoplastic with cardiomediastinal shift to the right. There was an abnormal right pulmonary vein draining into the inferior vena cava on the lower zone of the right lung (scimitar vein). The posterobasal portions of the both lungs were fused through a midline isthmus behind the heart.Publication Superb microvascular imaging in assessment of synovitis and tenosynovitis in juvenile idiopathic arthritis(Lippincott Williams & Wilkins, 2021-03-01) Kandemirli, Sedat Giray; Çicek, Fatih; Erdemli Gürsel, Başak; Bilgin, Cem; Kiliç, Sara Sebnem; Yazıcı, Zeynep; Çicek, Fatih; ÇİÇEK, FATİH; Erdemli Gürsel, Başak; ERDEMLİ GÜRSEL, BAŞAK; Bilgin, Cem; BİLGİN, CEM; Kiliç, Sara Sebnem; KILIÇ GÜLTEKİN, SARA ŞEBNEM; Yazıcı, Zeynep; YAZICI, ZEYNEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; 0000-0001-7348-7081; 0000-0001-8571-2581; AAH-1658-2021; HHS-7433-2022; JKI-5906-2023; AAH-6568-2021The aim of this study is to evaluate the diagnostic utility of superb microvascular imaging (SMI) in assessment of synovitis/tenosynovitis in juvenile idiopathic arthritis in comparison to power Doppler ultrasound. Thirty juvenile idiopathic arthritis cases with active clinical findings and ultrasound features of effusion and/or tenosynovitis were further imaged with power Doppler and SMI. For classification of synovial inflammation, a semiquantitative scale (4 points) adopted by Outcome Measures in Rheumatology was used.A total of 35 knee, 2 hip, 2 ankle, 2 wrist, 2 elbow joints, and 6 flexor hallucis longus/tibialis posterior tenosynovitis were assessed. In knee joint, power Doppler and SMI scales were the same for 23 (65.7%) joints, SMI upgraded scale from 0 to 2 in single joint (2.9%); 1 to 2 (14.3%) in 5 joints; and 2 to 3 (17.1%) in 6 joints. For other joints, power Doppler and SMI scales were the same for 5 (62.5%) joints. Superb microvascular imaging upgraded scale from 1 to 2 (25%) in 2 joints and 1 to 3 (12.5%) in a single joint. For flexor hallucis longus/tibialis posterior tenosynovitis, power Doppler and SMI scales were the same for two cases (33.3%). Superb microvascular imaging upgraded scale from 0 to 2 in two cases (33.3%); and 2 to 3 (33.3%) in 2 cases. There was no case of SMI scale downgraded compared with power Doppler scale.Superb microvascular imaging is a feasible technique in the assessment of synovial inflammation and tenosynovitis in juvenile idiopathic arthritis. Superb microvascular imaging has higher sensitivity compared with power Doppler ultrasound in depiction of increased vascularity.Publication Pituitary stalk interruption syndrome (psis) is not a rare cause of the congenital hypopituitarism(Karger, 2018-01-01) Eren, Erdal; Yazıcı, Zeynep; Demirbaş, Özgecan; Gülleroğlu, Nadide Başak; Tarım, Ömer; EREN, ERDAL; YAZICI, ZEYNEP; DEMİRBAŞ, ÖZGECAN; Gülleroğlu, Nadide Başak; TARIM, ÖMER FARUK; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Endokrinoloji Bölümü; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Radyoloji Bölümü; 0000-0002-1684-1053; 0000-0002-6922-5203; 0000-0002-5322-5508; AAI-2303-2021; JPK-3909-2023; GQX-9760-2022; EZQ-1350-2022; CCU-8073-2022Publication Re: "Optic nerve cyst-like formation presenting as a delayed complication of optic nerve sheath fenestration"(Lippincott Williams & Wilkins, 2015-03-01) Yazıcı, Bülent; Yazıcı, Zeynep; Yazıcı, Bülent; YAZICI, ZEYNEP; Bursa Uludağ Üniversitesi; 0000-0001-8889-1933; AAI-2303-2021; AAA-5384-2020Publication Secondary osteosarcomas diagnosed in a single institution: 7 cases in 10 years(Carbone Editore, 2015-05-02) Yalçınkaya, Ulviye; Çetintaş, Sibel Kahraman; Bilgen, Muhammed Sadık; Yazıcı, Zeynep; Sevinir, Berrin Betül; Aydınlı, Ufuk; YALÇINKAYA, ÜLVİYE; Çetintaş, Sibel Kahraman; Bilgen, Muhammed Sadık; YAZICI, ZEYNEP; SEVİNİR, BETÜL BERRİN; Uludağ Üniversitesi/Tıp Fakültesi/Cerrahi Patoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyasyon Onkolojisi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Pediatrik Onkoloji Anabilim Dalı.; 0000-0002-3232-7652; AAH-1570-2021; AAI-2303-2021; AAA-7047-2020; AAH-8924-2021; ELH-9133-2022Aims: Osteosarcoma is the most common, non-hematopoietic primary malignant tumor of bone. Osteosarcomas develop de novo in apparently normal bone. However, some benign bone tumors and non-neoplastic conditions may undergo malignant transformation into osteosarcomas. Such osteosarcomas are called secondary osteosarcoma. The scope of this article is to report on a ten-year experience of secondary osteosarcoma in a single institution.Materials and methods: The archives of Uludag University Medical School Department of Pathology were screened for cases of secondary osteosarcoma between January 2002 and June 2013. Demographics, clinical and pathological data are listed.Results: Of the 62 cases of osteosarcoma diagnosed in the period, 7 were secondary osteosarcomas. There were 5 male and 2 female patients. In 4 cases, the secondary osteosarcomas were due to radiation therapy. The index lesion was Paget's disease of bone, bone infarct and giant cell tumor of bone in the other cases. Index lesions included breast carcinoma, Ewing's sarcoma, rhabdomyosarcoma, and primitive neuroectodermal tumor for postradiation osteosarcomas. Unfortunately all patients passed away except for 3 cases of postradiation osteosarcoma.Conclusion: In cases of benign situations having a tendency of malignant transformation including giant cell tumor of bone, bone infarct, Paget's disease, and areas of former radiation therapy, clinical and radiological findings may be of great help in detecting in earlier stages of malignant transformation, and more promising for a disease free survival.
