[Emergency imaging in pregnant women]

BORBÉLY Krisztina, KATHIA Chaumoître, FORRAI Gábor

[The use of adequate imaging protocol reduces morbidity and mortality in emergency cases of pregnant women. The least harmful, but sufficiently informative imaging method should be chosen that provides us with the diagnosis in the shortest delay. Although the reduction of harmful effects is important, life threatening complications can be avoided by an indicated and well effectuated imaging method using ionizing radiation.]

[Pulmonary abnormalities in haematological malignancies - The role of imaging in differential]

GYŐRI Gabriella, MAGYAR Péter, KOVÁCS Balázs, BÉRCZI Viktor, BALASSA Katalin, DEMETER Judit

[Patients with hematological malignancies may develop a wide range of pulmonary abnormalities due to the hematological disease itself as well as in response to therapy. Immunosuppression and intensive chemotherapy induced severe neutropenia hold a high risk of infection. Infectionrelated morbidity and mortality are still high. One of the most common infectious complications is invasive mycosis, which is lethal in a high percentage of cases if not treated immediately and adequately. Non-infectious complications, such as secondary pulmonary lymphoma, thromboembolism, hemorrhage or drug induced fibrosis may develop during the course of the disease. Sometimes it is difficult to make a definitive diagnosis. As invasive methods (bronchoscopy, bronchoalveolar lavage, biopsy) are mostly contraindicated in these patients with severe neutropenia and thrombocytopenia, imaging techniques are especially important. It is a great challenge to differentiate infectious and noninfectious processes. CT and HRCT play an essential role in differential diagnosis. An early and accurate diagnosis is sometimes the only chance for survival.]

[Differential diagnosis of malignant cervical lymph nodes with real-time ultrasonographic elastography and Doppler ultrasonography]

ARDA Kemal, CILEDAG Nazan, GUMUSDAG Demir Pelin

[PURPOSE - Real-time ultrasonographic elastography is a new imaging technique which is used in characterizing the difference in hardness between pathologic and normal tissue. The purpose of our study was to evaluate the diagnostic performance of real-time ultrasonographic elastography and Doppler ultrasonography (DUS) individually and combined in differentiation of benign and malignant cervical lymph nodes (LN). PATIENTS AND METHODS - Fifty-one patients (12 men, 39 women) referred for fine-needle aspiration or surgical biopsies of suspected cervical lymph nodes were examined with gray scale ultrasonography, power DUS, and realtime ultrasonographic elastography. During DUS examination vascularity and resistance index (RI) values were evaluated. A five-group elastographic colour code pattern was used to evaluate the ultrasonographic elastograms for LN (pattern 1, an absent or a very small hard area; pattern 2, hard area <45%; pattern 3, hard area ≥45%; pattern 4, peripheral hard and central soft areas; pattern 5, hard area occupying entire solid component with or without soft rim). In addition, strains of LN and surrounding muscles were measured on elastograms, and the muscle-to-LN ratio (strain index) was calculated. Real-time ultrasonographic elastography and DUS results were compared with the final diagnosis obtained by fine-needle aspiration cytology analysis and/or by surgical pathology. The diagnostic potential of the examined criteria for malignancy was evaluated with univariate analysis and multivariate generalized estimating equation regression p≤0.05 indicated statistical significance. RESULTS - A strain index higher than 2.45 and colour pattern 4-5 had high utility in malignant LN classification with 93.8% sensitivity, 89.5% specificity (p<0.001). The results were significantly better than those obtained by using DUS characterization - that is, RI greater than 0.57 - which had 78.9% sensitivity (p<0.001). CONCLUSION - Real-time ultrasonographic elastography had 93.8% sensitivity and 89.5% specificity in the differentiation of benign and malignant cervical LN in patients referred for fine-needle aspiration or surgical biopsies with suspicion of malignancy. Real-time ultrasonographic elastography and DUS in addition to gray scale ultrasonography may improve the differential diagnosis of LN.]

[Interdisciplinary mummy research - Paleoradiology and paleopathology research of the Archbishop of Kalocsa Pál Széchényi’s mummy]

KRISTÓF Lilla Alida, POHÁRNOK László, KERÉNYI Tibor, TÓTH Vilmos, ISTÓK Roland, HARGITTAI Péter, FORNET Béla, PAP Ildikó, PÁLFI György

[Purpose - The scientific study of Pál Széchényi’s mummy was carried out by our research team composed of the members of several institutions in 2007 April. The scientific examinations represented a milestone, since up till now it was unclear whether it was a natural or artificial mummy and the century-old question whether Pál Széchényi was in fact a victim of arsenic poisoning in 1710 or it was only a legend could also be answered. Methods - The non-invasive examinations were carried out with multislice CT, traditional X-ray, biopsy, toxicology, energy-dispersive X-ray, X-ray fluorescens analysis, 3D optical digitalization indicator system, endoscope and 3D rapid-prototyping printing. Results - The examinations proved that Archbishop Pál Széchényi’s death was natural, and his body was artificially mummified. The CT examinations were carried out in a slice thickness of under 1 mm facilitating printed skull copy made by 3D rapid-prototyping method which provided the exact and detailed basis for the facial reconstruction.]

[Cases of inborn errors of metabolism diagnosed in children with autism ]

ÇAKAR Emel Nafiye, YILMAZBAŞ Pınar

[Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.]

[MR imaging of acute disseminated encephalomyelitis and multiple sclerosis in children. A review (in English language)]

PATAY Zoltán

[Inflammatory diseases of the central nervous system (CNS) are relatively rare in children, but their relevance to public health is considerable due to frequent and significant long term morbidity and even mortality. As in adults, acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS) and their variants are the most common entities in this group of pathologies in the pediatric patient population. Recent efforts have focused on establishing standardized diagnostic criteria schemes to facilitate the diagnosis and differential diagnosis of these diseases, however especially with multiple sclerosis those have not been fully validated yet for disease occurring in children. In recent decades the role of MRI has been constantly increasing in the diagnostic work-up of suspected inflammatory diseases of the CNS as well as in the follow-up of patients with confirmed disease. Currently, MRI is the first-line diagnostic imaging modality in ADEM and MS and is fully integrated in the most widely used diagnostic criteria schemes, but it has a key role in clinical therapeutic research trials as well. This paper provides an update on the current concepts and strategies of MRI in inflammatory diseases of the CNS, as well as a review of the imaging semiology of the various disease entities and variants with emphasis on clinical and imaging particularities relevant to the pediatric patient population.]

[Evaluation of arterial stiffness in children. Guidelines for the practice]

CSEPREKÁL Orsolya, KIS Éva, SZABÓ J. Attila, REUSZ György

[Assessment of early atherosclerosis and decreased arterial elasticity to recognise the cardiovascular dysfunction in high-risk patients has gained importance in the past decade. Since 1990, more than 630 papers have been published in the adult and pediatric literature. Methods of early risk assessment in adults are well determined in international recommendations. The aim of the present work is to review the suggestions of the American Heart Association helping us to find the most appropriate method for the non invasive methods of cardiovascular assessment of young adults and children. Furthermore, multicentric studies should be conducted to create a Framingham like score system for pediatric patients, to render cardiovascular risk assessment much easier for the every day routine.]
