Many studies have found a higher risk of revision after hip arthroplasty in younger patients. We evaluated the population-based survival of total hip arthroplasty (THA) in patients under 55 years of age and the factors affecting survival. ⋯ Modern uncemented stems seem to have better resistance to aseptic loosening than cemented stems in younger patients. Thus, for younger patients, uncemented proximally circumferentially porous- and HA-coated stems are the implants of choice. Press-fit porous- and HA-coated uncemented cups may have better endurance against aseptic loosening than cemented cups in younger patients. However, when all revisions (including exchange of liner) are taken into account, the survival of modern uncemented cups is no better than that of all-poly cemented cups.

Managing radiation exposure in children--reexamining the role of ultrasound in the diagnosis of appendicitis.
To assess the efficacy and accuracy of ultrasonography (US) and selective computed tomography (CT) in the diagnosis of acute appendicitis in children. ⋯ US followed by selective CT for the diagnosis of acute appendicitis is useful and accurate. This has important implications in the reduction of childhood radiation exposure.

Inguinal hernia is a common diagnosis for patients presenting with a painful groin mass; other potentially dangerous diagnoses may mimic a groin hernia. We present 3 unusual cases of diverticulitis with perforation. The resulting abscess presented clinically as an atypical strangulated inguinal hernia. ⋯ The diagnosis of strangulated inguinal hernias remains primarily one of clinical suspicion. Radiologic and laboratory studies should augment, not replace, one's clinical diagnosis. In addition, the differential diagnosis of inguinal masses is discussed.

Early intervention in management of very preterm growth-restricted fetuses: 2-year outcome of infants delivered on fetal indication before 30 gestational weeks.
To describe the outcome of growth-restricted fetuses with absent or reversed end-diastolic flow (ARED) in the umbilical artery delivered on fetal indication before 30 gestational weeks. ⋯ Very preterm growth-restricted fetuses with umbilical artery ARED delivered on fetal indication, in most cases before the occurrence of severe changes in the ductus venosus velocity waveforms and/or fetal heart rate tracings, showed high 2-year survival and low morbidity.

This investigation aimed to compare the accuracy of Bolton's analysis on plaster models of various malocclusion groups by utilizing digital calipers and iTero scanner. ⋯ With the introduction of intra-oral laser scanners it has become more convenient for the practitioner to perform the intra-oral digital scanning and carry out the model analysis digitally and iTero scanner can also be utilized extra-orally to perform the scanning and model analysis. Our study concludes that intra-oral laser scanner like iTero is more convenient for an orthodontist, and can be utilized for extra-oral scanning of orthodontic dental models as the measurements obtained on digital models was as accurate as the conventional method.
