Radiological and histological findings of two patients with fungal mycetoma of the foot are presented. MRI revealed multiple 2–5 mm lesions of high signal intensity interspersed within a low-intensity matrix. Within many of the lesions a minute low-intensity focus was identified. Ultrasound showed distinct hyperechoic foci within a hypoechoic mass. We(More)
OBJECTIVE To assess intra- and interobserver variability of fetal biometry measurements throughout pregnancy. METHODS A total of 175 scans (of 140 fetuses) were prospectively performed at 14-41 weeks of gestation ensuring an even distribution throughout gestation. From among three experienced sonographers, a pair of observers independently acquired a(More)
Volume charts of fetal organs and structures vary considerably among studies. This review identified 42 studies reporting normal volumes, namely for fetal brain (n = 3), cerebellum (n = 4), liver (n = 6), femur (n = 2), lungs (n = 15), kidneys (n = 3) and first-trimester embryo (n = 9). The differences among median volumes were expressed both in percentage(More)
The records of 56 patients in whom a hemiarthroplasty, carried out for a femoral neck fracture, had been revised to a total hip replacement, were reviewed. The mode of failure was femoral loosening in 21, acetabular erosion in 26 and both in 5. Loosening tended to occur earlier than acetabular erosion. The median time to the onset of symptoms was 12 months(More)
Meticulous standardisation and ongoing monitoring of adherence to measurement protocols during data collection are essential to ensure consistency and to minimise systematic error in multicentre studies. Strict ultrasound fetal biometric measurement protocols are used in the INTERGROWTH-21(st) Project so that data of the highest quality from different(More)
BACKGROUND Reliable ultrasound charts are necessary for the prenatal assessment of fetal size, yet there is a wide variation of methodologies for the creation of such charts. OBJECTIVE To evaluate the methodological quality of studies of fetal biometry using a set of predefined quality criteria of study design, statistical analysis and reporting methods.(More)
A unified protocol is essential to ensure that fetal ultrasound measurements taken in multicentre research studies are accurate and reproducible. This paper describes the methodology used to take two-dimensional, ultrasound measurements in the longitudinal, fetal growth component of the INTERGROWTH-21(st) Project. These standardised methods should minimise(More)
OBJECTIVE To assess whether a standardization exercise prior to commencing a fetal growth study involving multiple sonographers can reduce interobserver variation. METHODS In preparation for an international study assessing fetal growth, nine experienced sonographers from eight countries participated in a standardization exercise consisting of theoretical(More)
Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice. However, inconsistency in pregnancy dating may occur through differences in measurement methods or errors during measurement. In the INTERGROWTH-21(st) Project, pregnancies are dated by the last menstrual period, provided that it is(More)
