The vertical-centre-anterior margin (VCA) angle quantifies the anterior cover of the femoral head. However, when the femoral head is deformed it may be difficult to identify its centre. We have therefore created a new index, the anterior acetabular head index (AAHI) which is measured on the false-profile radiograph. We measured the VCA and AAHI angles in 312 hips in which the centre-edge angle ...

Subchondral insufficiency fracture (SIF) of the femoral head occurs in the elderly and recipients of organ transplantation. Osteoporosis and deficient lateral coverage of the acetabulum are known risk factors for SIF. There has been no study about relation between spinopelvic alignment and anterior acetabular coverage with SIF. We therefore asked whether a decrease of lumbar lordosis and a defi...

UNLABELLED The aim of the study was to compare the values of the sonographic inferior vena cava/ aorta index obtained with the transducer placed in the median line and right anterior axillary line. MATERIAL AND METHODS The study enrolled 45 volunteers, including 33 women, aged 22.5 ± 1.26 with a negative history of circulatory and renal diseases. The study consisted in a sonographic assessmen...

OBJECTIVE The treatment of craniofacial reconstructive surgery patients may benefit from comparison to average referent three-dimensional landmark data. These data may be useful for diagnosis, treatment planning, prosthetic design, or outcomes assessment. With regard to subadult patients, we hypothesize that the pattern of ontogenetic shape change of same sex, same ethnicity, referent populatio...

PURPOSE To investigate right ventricle function in successfully reperfused ST elevated myocardial infarction (STEMI) and to compare reperfusion strategies. METHODS From January 2007 to August 2008, 33 patients with anterior myocardial infarction (MI) and 48 patients with non-anterior myocardial infarction were enrolled in this study. Patients were treated with thrombolytic therapy (TT) or pri...

Background To compare the reliability and accuracy of direct and indirect dental measurements derived from two types of 3D virtual models: generated by intraoral laser scanning (ILS) and segmented cone beam computed tomography (CBCT), comparing these with a 2D digital model. Material and Methods One hundred patients were selected. All patients' records included initial plaster models, an intr...

The ant tribe Dacetini contains more than 800 species (Bolton et al. 2006). Many dacetine ants are specialized predators on soil inhabiting arthropods such as Collembola, Acarina, and to some extent also Diplura (Brown and Wilson 1959; Masuko 1984, 2009ab; Wilson 1953). Due to their peculiar morphological characteristics related to this specialized predation, dacetine ants have attracted the in...
