Anti-MFRP (aa 480-579) polyclonal antibody

Background To characterize the phenotype and genotype of a syndrome associating posterior microphthalmos (PM), retinitis pigmentosa (RP), foveoschisis, and foveal hypoplasia (FH) in a consanguineous Portuguese family. Materials and methods Three siblings were studied and underwent comprehensive eye examinations for best-corrected visual acuity, axial length, refractive error, B-mode ultrasound, electroretinography, retinography, fluorescein angiography (FA), kinetic visual field (VF), and optical coherence tomography (OCT). Molecular analysis was performed by Sanger sequencing of the entire coding region of theMFRPgene. Results All members presented nyctalopia, decreased visual acuity, and constriction of the VF, as well as bilateral shortening of the posterior ocular segment and normal anterior segment dimensions. The fundoscopy and ERG results were compatible with RP. Macular OCT analysis revealed schisis of the outer retinal layer, FH, as well as retinal and choroidal folds. We identified a homozygous mutation in intron 9 of the membrane frizzled-related protein (MFRP) gene (c.1124 + 1 G > A). Conclusions Our study shows a family with PM and RP due to a mutation in the MFRP gene. The relationship has previously been proven, but this specific mutation has never been described. These gene mutations show wide phenotypic variability, being evident in the presence of foveoschisis, retinal and choroidal folds, and FH, other than PM and RP.

Objective. Functional restoration programs for chronic low back pain (CLBP) have been shown to be successful in improving function and, to a lesser extent, in reducing pain. The Munich Functional Restoration Program (MFRP) is a 4-week outpatient program designed to reduce pain and to improve health-related quality of life in patients with a long history of CLBP. Design. In a retrospective matched concurrent-controls therapeutic study, 44 patients with CLBP, who had either undergone MFRP or received an outpatient standard treatment (control) after initial evaluation at the pain center, completed questionnaires 1 year after the respective therapy (t1). The following parameters were assessed: health-related quality of life with Short Form-36 (SF-36), Pain Disability Index (PDI), Numeric Rating Scale (NRS) for pain, depression with the Center for Epidemiological Studies Depression Test (CES-D), and occupational situation. These data were compared with baseline values assessed by a questionnaire completed before starting the respective treatment (baseline, t0). Results. Compared with control, NRS and PDT were significantly better in patients completing the MFRP. Patients of the MFRP group showed also a significant reduction in CES-D as well as an improvement in three of eight SF-36 subscales. No changes were detected in the control group receiving standard treatment. Conclusions. Compared with standard treatment, a functional restoration program for CLBP significantly improves some aspects of health-related quality of life. It results in a decrease of pain and pain-related disability even in patients with a long history of CLBP.
