Abstract

Objectives The aim of this study is to describe the presentation, surgical management and perioperative outcome of cats with acetabular fractures. Methods Case records and radiographs of cats with acetabular fractures were reviewed from presentation to the end of follow-up. Surgical technique, complications, radiographic reduction and the presence of neurological deficits were recorded. Results Sixteen cats with 17 acetabular fractures met the inclusion criteria. All fractures were associated with concurrent orthopaedic injuries. All cats were either moderately or severely lame on presentation. Five fractures were stabilised using screws, wire, pins and polymethylmethacrylate, nine were repaired using a straight dynamic compression plate and three were repaired using a locking plate. Two of seven cats that were neurologically normal prior to surgery developed transient neuropraxia following surgery. There were three major complications and no minor complications. At the end of follow-up 3/16 cats had full function, whereas 13/16 had acceptable function. Conclusions and relevance All cats undergoing surgical stabilisation of acetabular fractures returned to full or acceptable function by the end of the follow-up period and there was a low number of intraoperative and short-term complications. Neurological deficits were common preoperatively, but the majority of these deficits had resolved by follow-up.

All fractures were associated with concurrent orthopaedic injuries. All cats were either moderately or severely lame on presentation. Five fractures were stabilised using screws, wire, pins and polymethylmethacrylate, nine were repaired using a straight dynamic compression plate and three were repaired using a locking plate.

Abstract

Double-polarization asymmetries for inclusive ep scattering were measured at Jefferson Lab using 2.6 and 4.3 GeV longitudinally polarized electrons incident on a longitudinally polarized NH3 target in the CLAS detector. The polarized structure function g(1)(x,Q2) was extracted throughout the nucleon resonance region and into the deep inelastic regime, for Q(2)=0.15-1.64 GeV2. The contributions to the first moment Gamma(1)(Q2)= integral g(1)(x,Q2) dx were determined up to Q(2)=1.2 GeV2. Using a parametrization for g(1) in the unmeasured low x regions, the complete first moment was estimated over this Q2 region. A rapid change in Gamma(1) is observed for Q21 GeV2, with a sign change near Q(2)=0.3 GeV2, indicating dominant contributions from the resonance region. At Q(2)=1.2 GeV2 our data are below the perturbative QCD evolved scaling value.

Abstract

Most of the few patients on record with renal foreign bodies have been adults in whom bullets or shell fragments had penetrated the kidney through the skin. In the few children reported, the portal of entry has usually been the mouth or the urethra, and hematuria or pyuria or both have been the most common findings. This article describes cases of renal foreign bodies in two childhood patients. The study findings emphasize the need of renal foreign bodies to be considered as a diagnostic possibility in the presence of otherwise inexplicable hematuria, bacilluria or pyuria in children.

Abstract

Double-polarization asymmetries for inclusive ep scattering were measured at Jefferson Lab using 2.6 and 4.3 GeV longitudinally polarized electrons incident on a longitudinally polarized NH3 target in the CLAS detector. The polarized structure function g(1)(x,Q2) was extracted throughout the nucleon resonance region and into the deep inelastic regime, for Q(2)=0.15-1.64 GeV2. The contributions to the first moment Gamma(1)(Q2)= integral g(1)(x,Q2) dx were determined up to Q(2)=1.2 GeV2. Using a parametrization for g(1) in the unmeasured low x regions, the complete first moment was estimated over this Q2 region. A rapid change in Gamma(1) is observed for Q2<1 GeV2, with a sign change near Q(2)=0.3 GeV2, indicating dominant contributions from the resonance region. At Q(2)=1.2 GeV2 our data are below the perturbative QCD evolved scaling value.
