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.Publication Normal or elevated prolactin is a good indicator to show pituitary stalk interruption syndrome in patients with multiple pituitary hormone deficiency(Walter De Gruyter Gmbh, 2022-09-23) Eren, Erdal; Öngen, Yasemin Denkboy; Özgür, Taner; Özpar, Rıfat; Demirbaş, Özgecan; Yazıcı, Zeynep; Tarım, Ömer; EREN, ERDAL; DENKBOY ÖNGEN, YASEMİN; ÖZGÜR, TANER; ÖZPAR, RİFAT; DEMİRBAŞ, ÖZGECAN; YAZICI, ZEYNEP; TARIM, ÖMER FARUK; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Endokrinolojisi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Radyolojisi Anabilim Dalı.; 0000-0002-1684-1053; 0000-0001-6649-9287; 0000-0002-6922-5203; 0000-0002-5322-5508; KHZ-1491-2024; JPK-3909-2023; AAH-5062-2021; AAI-2303-2021; FPE-9941-2022; GQX-9760-2022; CCU-8073-2022Objectives To determine the importance of serum prolactin (PRL) in the detection of pituitary stalk interruption syndrome (PSIS) in children with multiple pituitary hormone deficiency (MPHD). We hypothesized that PRL elevation might be a diagnostic indicator of pituitary stalk pathologies. Methods Clinical, radiological, and laboratory features of the 50 cases of MPHD were studied. Results The median age at presentation of the 50 cases (52%, n=26 were female) was 6.61 (0.02-18.9) years. PSIS was detected in 60% (n=30), pituitary hypoplasia in 32% (n=16), partial empty sella in 6% (n=3), and only 2% (n=1) was reported as normal. Out of 50 patients, 21.3% (n=10) were hypoprolactinemic, 44.7% (n=19) were normoprolactinemic, and 34% (n=16) were hyperprolactinemic. The median PRL value was 27.85 (4.21-130) ng/mL in patients with PSIS and 5.57 (0-41.8) ng/mL in patients without PSIS. Additional hormone deficiencies, especially ACTH and LH were detected in follow-up. Conclusions Patients with normal or high prolactin levels deserve special attention regarding the possibility of PSIS. Furthermore, we emphasize the importance of regular follow-up and monitoring for multiple pituitary hormone deficiencies in all patients with a single pituitary hormone deficiency.Publication Fibrous dysplasia: Clinicopathologic presentation of 36 cases(De Gruyter Poland Sp Zoo, 2018-09-01) Özsen, Mine; ÖZŞEN, MİNE; Yalçınkaya, Ulviye; YALÇINKAYA, ÜLVİYE; Bilgen, Muhammed Sadık; Yazıcı, Zeynep; YAZICI, ZEYNEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi Anabilim Dalı.; 0000-0002-5771-7649; AAI-2303-2021; AAH-8924-2021; AAI-1609-2021Objective: Fibrous dysplasia is a slowly progressing bone lesion resulting from displacement of the normal medullary bone with abnormal fibroosseous tissue. The aim of this study was to assess the similarities and differences of our cases in relation to published reports.Material and Method: In this study, the archives of the Uludag University Medical Faculty Department of Pathology were screened for fibrous dysplasia cases between 2004 and 2016.Results: Within the mentioned period, there were 36 cases diagnosed as fibrous dysplasia. There were 21 male, and 15 female cases with an average age of 27.8 +/- 14.8 years (range 7-79 years). The most frequently affected sites were femur, costae, and craniofacial bones. There was one case localized to metacarpal bone, a very rare affection site. There were 4 polyostotic cases including 2 cases of McCune-Albright syndrome. Pelvic bone was affected in the polyostotic type, similar to published reports. Unlike former reports, however, long tubular bones were affected in male patients in our series. In our series, 32 cases had classical fibrous dysplasia, 3 cases had fibrocartilaginous, and one case had fibroosseous variants. Four cases localized to costae were accompanied by aneurysmal bone cyst. The presenting symptom was pathological fractures in a total of 4 cases, 3 localized to the femur, and 1 to the costa. Recurrence occurred in 5 cases treated with curettage. Two of the monostotic fibrous dysplasia cases developed malignant transformation into osteosarcoma.Conclusion: We conclude that our series of fibrous dysplasia cases have slight differences and mainly similar characteristics with the series reported earlier, when all features are taken into consideration.Publication Clavicle duplication following physeal injury(Springer France, 2019-04-01) Kandemirli, Sedat Giray; Kabar, Feyza; Kandemirli, Güzin Çakır; Gülleroğlu, Nadide Başak; Yazıcı, Zeynep; Kandemirli, Sedat Giray; KABAR, FEYZA; Kandemirli, Güzin Çakır; Gülleroğlu, Nadide Başak; YAZICI, ZEYNEP; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Fiziksel Tıp ve Rehabilitasyon Anabilim Dalı.; AAI-2303-2021; A-1409-2017; FCU-5534-2022; CXO-0560-2022; EZQ-1350-2022Clavicle duplication is a rare entity with limited number of cases reported. Congenital origin and trauma related mechanisms are the main hypotheses to explain this anatomical variation. In skeletally immature patient, trauma may cause physeal-metaphyseal injury in the distal clavicle rather than acromioclavicular strain. The distal epiphysis remains in continuity with acromion and has an intact periosteal sleeve. The periosteal sleeve is extremely osteogenic, and may lead to new bone formation between epiphysis and displaced metaphysis. This remodeling potential and the intact acromioclavicular joint allow the children to be followed by closed reduction. However, there can be new bone formation between epiphysis and displaced metaphysis, resulting in clavicle duplication. Herein, we present the radiographic and computed tomography findings of a post-traumatic duplication of the clavicle in a 5-year-old boy.Publication Prenatal diagnosis of fetal umbilical cord teratoma(Walter De Gruyter Gmbh, 2014-08-01) Demir, Bilge Çetinkaya; Topal, Naile Bolca; Güneş, Esra Şahin; Yazıcı, Zeynep; Yalçınkaya, Ulviye; ÇETİNKAYA DEMİR, BİLGE; BOLCA TOPAL, NAİLE; Güneş, Esra Şahin; YAZICI, ZEYNEP; YALÇINKAYA, ÜLVİYE; Uludağ Üniversitesi/Tıp Fakültesi/Kadın Hastalıkları ve Doğum Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; 0000-0001-6845-9991; AAH-9834-2021; AAH-8924-2021; AAI-2327-2021; AAI-2303-2021; IDE-0603-2023Umbilical cord teratomas are rare tumoral lesions of umbilical cord which have challenging antenatal diagnosis. The cord teratomas contain tissue from all three germ layers and have both cystic and solid components. This ultrasonographic appearance may help the clinician to clarify the correct diagnosis. We report a case of cord teratoma diagnosed prenatally by ultrasonography and magnetic resonance imaging. Since cord teratomas may lead to adverse fetal outcomes, close follow-up of the fetus is recommended.
