1. Mediastinal teratoma with hydrops fetalis in a newborn and development of chronic respiratory insufficiencyMilanka Simončič, Silvester Kopriva, Živa Zupančič, Maja Jerše, Janez Babnik, Matevž Srpčič, Štefan Grosek, 2014, pregledni znanstveni članek Povzetek: Background. Mediastinal fetal teratoma can be detected as a mass in the chest during a routine prenatal ultrasound screening. Because of the pressure on mediastinal structures it can be the cause of non-immune hydrops fetalis and polyhydramnion. The development of hydrops fetalis leads to fetal death or premature delivery in most reported cases. Early surgical removal is important, but, the result of treatment depends on the stage of development of mediastinal organs and complications in the postoperative period. Case report. A 31-year-old gravida carrying twins, with spontaneous membrane rupture at 32 weeks gestation underwent urgent caesarean section after antenatal ultrasound revealed severe polyhydramnion and hydrops fetalis in geminus A. The child was intubated immediately after birth due to severe respiratory distress. Ultrasound and X-ray revealed a tumour mass in the right hemithorax. Tumour resection was performed at the age of 7 days. Histology examination revealed an encapsulated immature teratoma. The postoperative course was complicated with respiratory insufficiency which turned into chronic at the age of eight months. Conclusion. This is the fifth reported child with fetal mediastinal teratoma and severe hydrops fetalis that survived the neonatal period. Additional diagnostic search revealed abnormal course of both pulmonary arteries, which was probably one of the main causes of respiratory insufficiency.

2. The role of sonographic evaluation of spinal canal in childrenŽiva Zupančič, 2000, pregledni znanstveni članek Povzetek: Background. Spinal sonography is a valuable diagnostic imaging modality as it has the ability to demonstrate good anatomic detail of the spinal canal, its contents, and the surrounding structures. The examination technique, the anatomy of the cord, the most common anomalies, and the evaluation of the sonography compared to magnetic resonance imaging are presented. Conclusions. Spinal sonography is recommended as the primary imaging modality for congenital anomalies of the lower spine in infants and as the screening modality for closed spinal dysraphism in infants and small children. The examination technique, the anatomy of the cord, the most common anomalies, andthe evaluation of the sonography compared to magnetic resonance imaging arepresented.

3. Ultrasound-guided aspiration biopsy of subclinical regional metastases of head and neck carcinomaAlenka Višnar-Perovič, Aleksandar Aničin, Živa Zupančič, Bojana Černelč, Alojz Šmid, Dubravka Vidmar, Milan Gorenc, 2000, izvirni znanstveni članek Povzetek: Background. Studies concerned with the estimation of ultrasound (US) combined with ultrasound-guided aspiration biopsy (USGAB) in the detection of subclinical regional metastases from the planocellular carcinoma of head and neck are promising, but in few cases. Recently, the authors have pointed out the role of lymph node size parameters in order to decide about the use of USGAB. The aim of this study was to test the reliability of US-USGAB for the detection of subclinical regional metastases in patients with planocellular head and neck carcinomas, including the evaluation of lymph node size parameters. Patients and methods. 121 neck sides with no palpable metastases were examined by US in 77 patients with planocellular carcinomas of head and neck. Depending on the results obtained, USGAB was performed on 64 neck sides.After surgery, the results of US-USGAB were compared with histological findings of the dissected lymph nodes. Results. The study showed 77% overall sensitivity of US and USGAB, and 100% specificity, while the versal / longiyudinal diameter was the best predictor of metastatic lymph node involvement. Conclusion. The results of this study established that USGAB is an appropriate method for detection the subclinical regional metastases on neck, and should be included into routine diagnostic work up in the evaluationof the extent of head and necks carcinomas.
