Sciatic Neuroma Presenting Forty Years After Above-Knee Amputation
We report a case of a sciatic neuroma presenting forty years after above knee amputation. Patients developing neuroma following a limb amputation can present with stump pain which is commonly resistant to medical intervention. The length of interval from the initial injury to presentation is widely variable. Diagnosis relies on clinical suspicion and accurate assessment, radiological imaging and, if indicated, surgical exploration. MRI provides a better soft tissue definition than CT and is more accurate in identifying small lesions than ultrasound. The aim of treatment for symptomatic neuroma is pain relief and improvement of function. This is often achieved by surgical excision
Nutraceutical agents with anti-inflammatory properties prevent dietary saturated-fat induced disturbances in blood-brain barrier function in wild-type mice
Background: Emerging evidence suggests that disturbances in the blood–brain barrier (BBB) may be pivotal to the pathogenesis and pathology of vascular-based neurodegenerative disorders. Studies suggest that heightened systemic and central inflammations are associated with BBB dysfunction. This study investigated the effect of the anti-inflammatory nutraceuticals garlic extract-aged (GEA), alpha lipoic acid (ALA), niacin, and nicotinamide (NA) in a murine dietary-induced model of BBB dysfunction. Methods: C57BL/6 mice were fed a diet enriched in saturated fatty acids (SFA, 40% fat of total energy) for nine months to induce systemic inflammation and BBB disturbances. Nutraceutical treatment groups included the provision of either GEA, ALA, niacin or NA in the positive control SFA-group and in low-fat fed controls. Brain parenchymal extravasation of plasma derived immunoglobulin G (IgG) and large macromolecules (apolipoprotein (apo) B lipoproteins) measured by quantitative immunofluorescent microscopy, were used as markers of disturbed BBB integrity. Parenchymal glial fibrillar acidic protein (GFAP) and cyclooxygenase-2 (COX-2) were considered in the context of surrogate markers of neurovascular inflammation and oxidative stress. Total anti-oxidant status and glutathione reductase activity were determined in plasma.Results: Brain parenchymal abundance of IgG and apoB lipoproteins was markedly exaggerated in mice maintained on the SFA diet concomitant with significantly increased GFAP and COX-2, and reduced systemic antioxidative status. The nutraceutical GEA, ALA, niacin, and NA completely prevented the SFA-induced disturbances of BBB and normalized the measures of neurovascular inflammation and oxidative stress. Conclusions: The anti-inflammatory nutraceutical agents GEA, ALA, niacin, or NA are potent inhibitors of dietary fat-induced disturbances of BBB induced by systemic inflammations

Pediatric Microvascular Reconstruction: A Report from the Microvascular Committee
Free tissue transfer is an integral part of modern head and neck surgery in the adult population. Its use in the pediatric population has not been well described. Recently, there has been an increase in the application of these techniques in the pediatric population. The morbidity of free tissue transfer in small pediatric patients and its effect on growth has not been well described.
To evaluate the utility of microvascular reconstruction techniques in the pediatric population.
A consensus study was performed by the microvascular committee of the American Academy of Otolaryngology-Head and Neck Surgery. Thirty active microvascular surgeons reviewed their databases to find patients less than 21 years of age who underwent free tissue transfer.
49 free tissue transfers performed between 1999 and 2005. The mean age was 12.1 years (age range, 3-21). The types of flaps transferred were radial forearm (10), fibula (21), rectus abdominus (7), scapula (1), latissimus dorsi (3), groin (1), gracillus (4), and jejunum (2). Morbidity at the donor site was relatively minimal. Five patients developed wound breakdown. One of these required return to the operating room. Morbidity at the reconstructed site was also rare. Patients were followed for an average of 49 months (range, 1-131 months), and no problems were noted with growth at the donor or recipient sites.
Free flaps in the pediatric population have morbidity and survival similar to those in the adult population.
While indications differ from those in the adult population, these techniques are viable and valuable and should be considered in the pediatric reconstructive paradigm
