Data comes from ten pigs, across two protocols testing the algorithms under different hemodynamic states. The resulting mean difference ± limits of agreement between measured and estimated systolic duration, of [Formula see text] versus [Formula see text], for the new and existing algorithms respectively, indicate the new algorithms superiority.BACKGROUND Cockayne syndrome is a rare autosomal recessive neurodegenerative disorder caused by mutations of either the ERCC6/CSB or ERCC8/CSA genes. Here, we describe two sisters with Cockayne syndrome caused by compound heterozygous mutations in the ERCC8 gene using multimodal imaging. Significant ophthalmic and systemic phenotypic variability is discussed. MATERIALS AND METHODS Multimodal imaging was performed in two affected sisters and included electroretinography, optical coherence tomography, ultra-wide-field confocal scanning laser ophthalmoscopy, fundus autofluorescence and fluorescein angiography, and magnetic resonance imaging. Genetic analyses were performed on the affected sisters, both parents, and three unaffected siblings. RESULTS The older sister (Patient 1) had mental retardation, bilateral hearing loss, ataxia, and decreased visual acuity with retinal dystrophy. Radiographic studies revealed microcephaly, cerebral and cerebellar atrophy, ventriculomegaly, and a diffusely thickened skull. Fur imaging and systemic findings revealed wide phenotypic variability between the affected siblings.BACKGROUND A number of clinical trials have been published assessing the role of iliac crest bone grafting for the management of recurrent anterior instability with glenoid bone loss in contemporary practice. We therefore performed a systematic review of contemporary literature to examine the effect of iliac
