Biplanar flap reconstruction for pressure ulcers: experience in patients with immobility from chronic spinal cord injuries

BackgroundSurgical therapy for advanced-stage pressure ulcers recalcitrant to healing is a widely accepted practice. The present study examined the incidence of wound recurrence after reconstruction with fasciocutaneous versus combined (biplanar) muscle and fasciocutaneous flaps.MethodsA retrospective review identified 90 nonambulatory patients with spinal cord injury who underwent reconstruction for persistent decubitus ulcers from 2002 to 2008. Electronic medical records were surveyed for patient comorbidities and postoperative complications. Statistical methods included the Fisher exact test and the Mann–Whitney U test with a 2-sided P value of less than .05.ResultsAmong 90 patients reviewed, 33% (n = 30) received fasciocutaneous flaps and 66% (n = 60) underwent biplanar reconstruction. Comorbidities were the same between cohorts with the exception of a greater prevalence of diabetes in the biplanar group (27% vs 50%; P < .05). The incidence of recurrence for biplanar flaps (25%) was significantly lower than for fasciocutaneous reconstruction (53%; P < .01).ConclusionsBiplanar flap reconstruction should be considered for chronically immobilized patients at high risk for recurrent decubitus ulceration.     

Adaptive optics imaging of the retina

Adaptive optics is a relatively new tool that is available to ophthalmologists for study of cellular level details. In addition to the axial resolution provided by the spectral-domain optical coherence tomography, adaptive optics provides an excellent lateral resolution, enabling visualization of the photoreceptors, blood vessels and details of the optic nerve head. We attempt a mini review of the current role of adaptive optics in retinal imaging. PubMed search was performed with key words Adaptive optics OR Retina OR Retinal imaging. Conference abstracts were searched from the Association for Research in Vision and Ophthalmology (ARVO) and American Academy of Ophthalmology (AAO) meetings. In total, 261 relevant publications and 389 conference abstracts were identified.     

Pseudoachondroplasia: A rare cause of rhizomelic dwarfism

Pseudoachondroplasia is a rare rhizomelic short-limbed skeletal dysplasia. Its inheritance is varied; autosomal dominant pattern and germline or somatic mutations can occur. Children at 2–3 years of age present with short height, gait disturbances, or limb deformities. Characteristic skeletal changes include shortening of long bones, predominantly of femur and humerus with irregular, flared metaphysis and fragmented epiphysis. Platyspondyly is also present, but the interpedicular distance is normal. The diagnosis is essentially based on imaging, and thus, it is important to be aware of the radiological features. Here, we report a case of two brothers where the elder sibling had classical radiological features of pseudoachondroplasia, whereas the younger one had early changes of this disorder.
