In the last decades, technological development has led to an increasing use of devices and systems based on microwave radiation. The increased employment of these devices has elicited questions about the potential long-term health consequences associated with microwave radiation exposure. From this perspective, biological effects of microwave radiation have been the focus of many studies, but the reported scientific data are unclear and contradictory. The aim of this study is to evaluate the potential ...

Müllerian duct anomalies (MDAs) are congenital entities that result from nondevelopment, defective vertical or lateral fusion, or resorption failure of the müllerian (paramesonephric) ducts. MDAs are common, although the majority are asymptomatic, and have been classified by the American Society of Reproductive Medicine according to clinical manifestations, prognosis, and treatment. Accurate diagnosis of an MDA is essential, since the management approach varies depending on the type of malformation. ...

A total of 26 children (26 affected, 25 control hips) with Legg-Calvé-Perthes' disease (LCP) met the cooperation requirements for inclusion in the study using contrast-enhanced power Doppler sonography for assessment of changes in the revascularization flow. Sagittal sonograms were obtained before and at the peak effect of an intravenously injected microbubble-based contrast agent. Overall mean peak enhancement ratios were greater for children with later onset of disease (>5.8 years old) than for those ...

Haemophilia is a sex-linked inherited disorder caused by deficiencies of coagulation factor VIII (haemophilia A) or IX (haemophilia B) [1]. The disorder occurs in all ethnic groups with an estimated frequency of 1 per 5–10 000 live male births. The ratio of haemophilia A to B cases is approximately 4:1. Traditionally, the haemophilias are classified as severe, moderate or mild based on circulating factor levels 5%, respectively. In many European centres a factor level of 1/3 of the surface), ...

Summary. In spite of the fact that the diagnosis of haemophilia is essentially clinical and laboratory‐based, imaging has become an important tool for the evaluation of complications, diagnostic confirmation and/or complementation and therapeutic follow‐up in haemophilic arthropathy. Radiography remains the workforce horse in the diagnosis and follow‐up of haemophilic arthropathy. The radiographical findings in arthropathy follow an expected sequence of events and are overall similar in different ...

The study of the potential effects of Terahertz radiation on biological systems is therefore an important issue in order to safely develop a variety of applications. This paper describes a pilot study devoted to determine if Terahertz radiation could induce genotoxic effects in human peripheral blood leukocytes. For this purpose, human whole ...

Summary. Radiological imaging of joints in children with haemophilia is important to detect abnormalities, grade their severity and monitor the effects of treatment. Scoring systems for staging haemophilic arthropathy have been developed based on plain film or magnetic resonance imaging (MRI) findings. Radiographs alone may be inadequate for evaluating joint disease in children with haemophilia on prophylaxis while MRI may be difficult to access and require the child to be sedated. Sonography can ...

We assessed the reliability and construct validity of the Compatible MRI scale for evaluation of elbows, and compared the diagnostic performance of MRI and radiographs for assessment of these joints. Twenty‐nine MR examinations of elbows from 27 boys with haemophilia A and B [age range, 5–17 years (mean, 11.5)] were independently read by four blinded radiologists on two occasions. Three centres participated in the study: (Toronto, n = 24 examinations; Atlanta, n = 3; Cuiaba, n = 2). The number of ...

Furthermore, the imaging route consisting of the screening US with a second US if necessary has a significantly lower diagnostic accuracy in the obese children (83%) than their lean counterparts (93%). However, the effect of this association on clinical outcomes in the obese ...

Osteonecrosis (ON) is a major complication after treatment of developmental dysplasia of the hip (DDH). Several studies have explored the absence of the femoral head ossific nucleus at the time of hip reduction as a risk factor for the development of ON, but findings have been inconsistent.We therefore determined the incidence of ON in children who underwent reduction of a dislocated hip in the presence or absence of the ossific nucleus.We retrospectively reviewed the radiographs of 105 hips in 89 ...
