Increasing experience with coronary CT angiography improved the diagnostic performance of inexperienced physicians. However, acquiring expertise in coronary CT angiography was slow and may take more than 1 year.
Atresias of nasal cavity, especially in young children, pose an essential problem in children's otolaryngology. Only a few morphometric studies of nasal cavity concerning healthy neonates and young infants without nasal stenosis are available. Multislice computed tomography is a perfect tool enabling a precise evaluation of anatomic structures. The aim of this study was a complex morphometric evaluation of clinically important bone and mucosal structures of nasal cavity and examination of their dependence on age and sex in children up to 3 years of age. 180 children, age range 0–3 years, were divided into 5 age groups, and measurements of 18 distances between skeletal structures and between mucosal structures of nasal cavity were performed on their CT scans. A correlation between the widths of selected bone structures was examined.
There were no statistically significant differences in analyzed morphometric parameters between adjacent age groups. The differences were statistically significant only between extreme age groups. There was a correlation between evaluated structures and age. Our results are a valuable supplement of nasal cavity morphometric data of young children. They may be useful in setting reference values of evaluated parameters in children and in diagnosis and planning of surgical treatment in children's otolaryngology.
The pandemic involving COVID-19 caused by the SARS-CoV-2 coronavirus, due to its severe symptoms and high transmission rate, has gone on to pose a control challenge for healthcare systems all around the world. We present the second version of the Recommendations of the Polish Medical Society of Radiology, presuming that our knowledge on COVID-19 will advance further rapidly, to the extent that further supplementation and modification will prove necessary. These Recommendations involve rules of conduct, procedures, and safety measures that should be introduced in radiology departments, as well as indications for imaging studies.
IntroductionThe acute pancreatitis is a rare disease, but it has started to be diagnosed more often in children.AimThe aim of the study was single-centre, retrospective analysis of the incidence, aetiology, and clinical course of acute pancreatitis in children.Material and methodsWe analysed the medical records of patients with acute pancreatitis hospitalised in the Gastroenterology Unit of the Paediatrics Department, Medical University of Silesia from Jan 2004 to Dec 2013.ResultsThere were 76 cases of acute pancreatitis among 51 children (average age: 12.07 years) hospitalised in the Gastroenterology Unit between January 2004 and December 2013. The diagnosis of acute pancreatitis was performed on the basis of INSPIRE criteria and modified Atlanta classification. Patients were divided into groups: I – 1–12 years old, which included 20 (39.21%) children and II – 13–18 years old, with 31 (60.78%) children. The idiopathic aetiology was the most common cause of acute pancreatitis, occurring in 22 (43.1%) children, and in 15 cases the aetiology of the disease was biliary (29.4%). Genetically determined causes were diagnosed in 8 (15.7%) patients, the PRSS1 mutation in four patients, mutation in SPINK1 in 1 child, and CFTR gene mutation in 1 child. Two children simultaneously had two genes mutations (CFTR, SPINK1), and during the considered period had more than one episode of acute pancreatitis.ConclusionsAcute pancreatitis of idiopathic aetiology was most common among the examined children, and this should encourage the continued search for the causes of disease, especially genetic, and with particular emphasis on younger age group.
• Multislice computed tomography enables detection and evaluation of the coronary artery anomalies. • Anomalous anatomy of the coronary artery potentially influences the prevalence of adverse events. • Adverse events tend to be most common in anomalous right coronary arteries.
Introduction Posterior reversible leukoencephalopathy syndrome (PRES) is a clinical syndrome of varying aetiologies, characterised by acute neurological symptoms of brain dysfunction with MRI abnormalities in posterior cerebral white and grey matter. In most cases, symptoms resolve without neurological consequences. Aim The aim of this paper is the analysis of predisposing factors, clinical outcomes and radiological features of PRES in eight children with hemato-oncological disease. Material and methods We analysed the medical records of eight hemato-oncological patients aged from 3.0 to 16.1 years. The mean of age at primary diagnosis was 8.5 years. Results All patients had both clinical and radiological PRES features. Seven out of eight underwent intensive chemotherapy regimens. Time elapsed from start of treatment to the occurrence of PRES ranged from 6 to 556 days. In one case, PRES occurred before chemotherapy and was the first symptom of cancer. Most (six of eight) patients had history of hypertension (> 95pc) and some (two of eight) occurred electrolyte imbalance-mainly hypomagnesaemia. Patients presented headache (seven of eight), disturbances of consciousness (six of eight), seizures (six of eight), visual changes (four of eight) and vomiting (three of eight). MRI demonstrated abnormalities in seven children: typical cerebral oedema in the white matter of the occipital to the parietal lobes. Most patient lesions in the MRI shrunk after 4 weeks, and clinical symptoms of PRES disappeared completely within a few hours to few days. Conclusion PRES may complicate oncological treatment in children. Hypertension is the most important risk factor of PRES. PRES should be included in differential diagnosis in all patients with acute neurological symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
