Localized and circumferential atrophies of the lower extremities have been difficult to treat with few simple autologous solutions available. The aim of this study was to analyze the efficacy of fat grafting in lower limb atrophies. There were 20 patients (17 females and 3 males) at an average age of 33 years. Twelve patients had localized and 8 patients circumferential atrophies of various etiologies: traumatic (60%), congenital (25%), and iatrogenic (15%). The average number of fat injections was 1.1 per patient (range 1-2) for localized atrophies and 2.2 per patient (range 1-3) for circumferential atrophies. The average follow-up period was 2 years. The average volume injected at each stage was 79 mL for localized atrophies and 137 mL for circumferential atrophies. In the cases of circumferential atrophies, an average augmentation of 1.9 cm (range 1-6 cm) of the limb perimeter per injection was achieved. The overall satisfaction of the patients was high. Autologous fat grafting is a reliable technique for lower limb atrophies.

Multimodal Evaluation and Management of Wagner Syndrome-Three Patients from an Affected Family.

Wagner syndrome is a rare autosomal dominant vitreoretinopathy caused by mutations in chondroitin sulphate proteoglycan 2 (CSPG2)/Versican (VCAN). Here, we present a retrospective case series of a family pedigree with genetically confirmed Wagner syndrome (heterozygous VCAN exon 8 deletion), as follows: a 34-year-old mother (P1), 12-year-old daughter (P2), and a 2-year-old son (P3). The phenotype included early-onset cataract (P1), optically empty vitreous with avascular membranes (P1, 2), nasal dragging of optic nerve heads associated with foveal hypoplasia (P1, 2), tractional retinoschisis on optical coherence tomography (P2), and peripheral circumferential vitreo-retinal interface abnormality resembling white-without-pressure (P3) progressing to pigmented chorio-retinal atrophy (P1, 2).

Developing long bones alter their shape while maintaining uniform cortical thickness via coordinated activity of bone-forming osteoblasts and bone-resorbing osteoclasts at periosteal and endosteal surfaces, a process we designate trans-pairing. Two types of trans-pairing shift cortical bone in opposite orientations: peri-forming trans-pairing (peri-t-p) increases bone marrow space and endo-forming trans-pairing (endo-t-p) decreases it, via paired activity of bone resorption and formation across the cortex. Here, we focused on endo-t-p in growing bones.

A 63-year-old female patient presented with "flashes of light in both eyes accompanied by decreased visual acuity for one year." Visual field examination revealed partial defects in the central 30° of the visual field in both eyes. Scanning laser ophthalmoscopy showed extensive atrophic lesions across the entire posterior pole of the retina in both eyes.

Aortitis is a rare disease entity of unknown prevalence. Primary aortitis mainly affects the thoracic aorta. They are most often diagnosed on imaging by grade III 18-FDG uptake of the aortic wall on PET, or by circumferential thickening>2.
