981. Cutaneous sclerosis: a previously undescribed manifestation of sclerosing mesenteritis. Full Text available with Trip Pro

with biopsy-proven MP presented with multiple asymptomatic, indurated subcutaneous nodules on both arms, as well as 2 indurated plaques on her abdomen. The cutaneous changes preceded the diagnosis of SM by roughly 3 years. The arm lesions were centrally depressed with a prominent groove and a peau d'orange appearance. Biopsy findings revealed a subcutaneous process with almost total replacement of adipocytes by zones of woody sclerosis and fat necrosis identical to that observed in the mesentery. To our

982. Combination excision and liposuction in a single-stage treatment of various skin disorders. (Abstract)

a harmonious result and simultaneously the body contour was well-balanced.Some large skin disorders at sites rich in subcutaneous fat can be treated in one stage by combining excision and liposuction with good functional and esthetic outcomes with few complications. Although the indications for this technique are limited, it is really a good option for appropriate cases. (...) by complete excision. The sliding flaps on both sides of the defect created by liposuction were pulled together to cover the defect. In our study, 40 skin disorders located on the upper arm, thigh, and trunk were treated by this technique.Forty skin disorders were excised and resulting skin defects were repaired in one stage by the surrounding sliding flaps without wound dehiscence, infection, incision edge necrosis, sensory deficit, or severe scar recurrence. The regions of liposuction presented

of adult trauma patients requiring >48 hours of intensive care unit care over a 55-month period was analyzed. Body fat distribution was determined by radiologist review of computed tomography scans at L1. Concentric freeform regions were defined manually, and area was calculated. Visceral adiposity was defined as subcutaneous fat area: visceral area >1.35 (the median), whereas subcutaneous adiposity was defined as a ratio <1.35. Primary outcomes were proinflammatory biomarkers known to be associated (...) with chronic visceral obesity (white blood cell count, interleukin 1, 2, 4, 6, 8, 10, and tumor necrosis factor alpha). Secondary outcomes were all-cause in-hospital mortality, adult respiratory distress syndrome, and nosocomial infections.Two hundred eighty-one (19%) obese patients with available computed tomography scans from 1,510 trauma patients were included. Visceral adiposity included 140 patients, subcutaneous adiposity included 141 patients. The two groups were similar in regards to age, Trauma

984. Lupus Mastitis: An Uncommon Complication of Systemic or Discoid Lupus. (Abstract)

Lupus Mastitis: An Uncommon Complication of Systemic or Discoid Lupus. Lupus mastitis is an uncommon presentation of lupus erythematosus profundus or lupus panniculitis, a rare variant of lupus erythematosus characterized by inflammation of the subcutaneous fat. Lupus mastitis can present as single or multiple subcutaneous or deep breast masses, often clinically mimicking malignancy. Although lupus mastitis is rare, with less than 25 cases reported, the histologic features are distinct (...) . Awareness of the entity and familiarity with the histologic features allow for accurate diagnosis and appropriate patient management. It most commonly affects women with a mean age at diagnosis of 40 years and an age range of 18 to 70 years. Typical histologic findings in lupus mastitis include a lymphocytic lobular panniculitis with plasma cells and hyaline fat necrosis. The lymphocytic infiltrate can be nodular, diffuse, periductal, and/or perilobular and germinal centers can frequently be identified

985. The Occlusive Dressing

amputations are very common injuries among the patients arriving at the Emergency Department. Fingertips amputations classified in 2nd and 3rd zones, in accordance with Rosenthal's classification (after the solum unguis), constitute a large proportion of them. The treatment aims at restoring a pulp with its sensitivity and a good subcutaneous fat tissue. The usual care of these amputations is a surgical treatment: it consists of pulp reconstruction by a flap (for example palmar V-Y advancement flaps (...) of Atazoy). These technique involve hospital admission, brachial plexus anaesthesia, a surgical approach with cicatrix and donor site morbidities, postoperative cares, post-surgical pain management. And of course attention must be paid to the risks of postoperative complications related either to anaesthesia and/or to surgery, like necrosis, infection, and others. We have developed a nonoperative treatment for fingertips amputations: the occlusive dressing. It's a technique that has been known for about

986. Excision of Strip of Deep Fascia to Reduce Seroma Formation and Extrusion of Tissue Expanders

in mitosis returned to normal 4 weeks after expansion. The dermis and subcutaneous tissues were thinned as a result of tissue expansion leading to an overall decrease in tensile strength of the expanded skin (5-7) and this persisted 36 weeks after expansion. The subcutaneous layer of fat was intolerant to stretching causing significant thinning. With faster expansion, fat necrosis could be seen. Pressure necrosis on subcutaneous fat led to liquefaction and seroma formation. With progression of expansion (...) University Information provided by: Cairo University Study Details Study Description Go to Brief Summary: Tissue expansion has enjoyed a wide range of applications since the technique was popularized in the latter quarter of the last century. During the expansion process, subcutaneous fat liquefies, skin becomes thinner, muscles atrophy, blood inflow increases, and lymphatics get occluded. All these factors predispose to seroma formation and implant extrusion. A similar problem occurred with lymphoedema

991. Local Inflammation and Hypoxia Abolish the Protective Anticontractile Properties of Perivascular Fat in Obese Patients. Full Text available with Trip Pro

Local Inflammation and Hypoxia Abolish the Protective Anticontractile Properties of Perivascular Fat in Obese Patients. Inflammation in adipose tissue has been implicated in vascular dysfunction, but the local mechanisms by which this occurs are unknown.Small arteries with and without perivascular adipose tissue were taken from subcutaneous gluteal fat biopsy samples and studied with wire myography and immunohistochemistry. We established that healthy adipose tissue around human small arteries (...) necrosis factor receptor 1 12.4+/-1.1% versus 6.7+/-1%, P<0.001). Application of the cytokines tumor necrosis factor receptor-alpha and interleukin-6 to perivascular fat around healthy blood vessels reduced dilator activity, resulting in the obese phenotype. These effects could be reversed with free radical scavengers or cytokine antagonists. Similarly, induction of hypoxia stimulated inflammation and resulted in loss of anticontractile capacity, which could be rescued by catalase and superoxide

Subcutaneous and Visceral Adipose Tissue Gene Expression of Serum Adipokines That Predict Type 2 Diabetes. Type 2 diabetes mellitus (T2D) is predicted by central obesity and circulating adipokines regulating inflammation. We hypothesized that visceral adipose tissue (VAT) in T2D expresses greater levels of proinflammatory molecules. Paired samples of subcutaneous (SAT) and VAT were excised at elective surgery (n = 16, 6 with T2D, n = 8 age- and gender- matched controls). Metabolic parameters (...) were measured in the fasted state: body composition by dual-energy X-ray absorptiometry and insulin action by hyperinsulinemic-euglycemic clamp. Adipose tissue mRNA gene expression was measured by quantitative reverse transcriptase-PCR. Subjects with T2D had higher VAT expression of molecules regulating inflammation (tumor necrosis factor-alpha (TNFalpha), macrophage inflammatory protein (MIP), interleukin-8 (IL-8)). Fasting glucose related to VAT expression of TNFalpha, MIP, serum amyloid A (SAA

. Pressure was then periodically applied (2 hours compression, 1 hour recovery) using a Neodymium magnet in conjunction with the disk in the unanesthetized mouse. Cycles were repeated for 1, 4, 6, 8, or 10 times. Controls underwent the same procedure without placement of the magnet. The pressure ulcer grade was found to be cycle dependent,with the highest degree after 10 cycles. Histological evaluations revealed signs of necrosis in the skin and subcutaneous fat after four, and in the muscle after eight (...) A chronic pressure ulcer model in the nude mouse. The pathophysiology of pressure ulcers is not yet fully understood. Widely used experimental models lead to pressure ulcers in the skin and the subcutaneous tissue only. The aim of the present study was to develop a clinically relevant deep pressure ulcer model in nude mice involving all relevant tissue layers. Balb/c nude mice were anesthetized and a steel disk was implanted under the great gluteus muscle. Full recovery was allowed for 10 days

. Epidemiology Mycobacterium ulcerans was discovered in 1948 by Australian scientists who were investigating a cluster of patients with unusual skin ulcers in the Bairnsdale region of eastern Victoria. M. ulcerans is related to the causative agents of tuberculosis and leprosy, but is transmitted from the environment rather than from person to person. The major virulence factor is a lipid toxin, mycolactone, which causes necrosis of fat and subcutaneous tissue. M. ulcerans infection is not fatal, but can (...) that undergoes necrosis and evolves to a deeply undermined ulcer. Lesions are usually painless or minimally painful. Less commonly, the initial lesion may resemble a plaque or necrotic patch of skin. Systemic symptoms (fever, malaise) are rare. Fully developed ulcers are characteristically deeply undermined, meaning a probe can be passed easily under the edge into the space left by necrotic liquefied fat tissue. Lesions can occur anywhere and may be multiple, but a single lesion on the leg or arm is most
