A radiographic scoring system to assess healing in congenital pseudarthrosis of the tibia.

The aim of this study was to determine whether an established radiographic union scoring system for tibial fracture healing (RUST) is reliable when used in neurofibromatosis (NF1) patients with congenital pseudarthrosis of the tibia (CPT) treated by intramedullary fixation. Four individuals reviewed 36 sets of radiographs from 12 NF1 patients with CPT (preoperative, and 6 months and 1 year postoperative). Intraobserver reliability (κ-value 0.

Polycystic ovarian syndrome and subclinical atherosclerosis among women of reproductive age in the Dallas heart study.

Objective: Polycystic ovarian syndrome (PCOS), the most common endocrinopathy of young women, is characterized by androgen excess and is frequently associated with cardiovascular risk factors. However, it is unclear whether PCOS is a risk factor for atherosclerosis. We sought to determine in a multiethnic population-based sample whether women with PCOS have greater measures of subclinical atherosclerosis than women without PCOS.

Morphometric Analysis of Vertebral Growth Using Magnetic Resonance Imaging in the Normal Skeletally Immature Spine.

Study Design: Morphometic analysis of the thoracic and lumbar pedicle, vertebral body, and spinal canal in the normal infantile and juvenile patients using magnetic resonance imaging (MRI).

Objective: To 3-dimensionally characterize the growth of the vertebral column in vivo and define the accurate dynamic growth rate of the normal immature spine.

Summary Of Background Data: There is a relationship between growth of the spine and the development of spinal deformity.

Morphometric analysis of neurocentral synchondrosis using magnetic resonance imaging in the normal skeletally immature spine.

Study Design: Morphometric analysis of the neurocentral synchondrosis (NCS) using magnetic resonance imaging in the normal infantile and juvenile patients.

Objectives: To assess the developmental stages of the neurocentral synchondrosis (NCS) by determining the age at which closure of the NCS occurs at specific levels of the spine and to evaluate whether symmetric growth of the NCS occurs during the different developmental stages in normal immature spine.

Summary Of Background Data: The function and developmental stage of the NCS are controversial because of a lack of agreement on the exact age of closure.

Magnetic resonance spectroscopy to measure hepatic triglyceride content: prevalence of hepatic steatosis in the general population.

Despite the increasing prevalence of nonalcoholic fatty liver disease (NAFLD), the criteria used to diagnose the disorder remain poorly defined. Localized proton magnetic resonance spectroscopy (MRS) accurately measures hepatic triglyceride content (HTGC) but has been used only in small research studies. Here, MRS was used to analyze the distribution of HTGC in 2,349 participants from the Dallas Heart Study (DHS).
