    Chest wall kinematics, respiratory muscle action and dyspnoea during arm vs. leg exercise in humans

    ACTA PHYSIOLOGICA, Issue 1 2006
    I. Romagnoli
    Abstract Aim:, We hypothesize that different patterns of chest wall (CW) kinematics and respiratory muscle coordination contribute to sensation of dyspnoea during unsupported arm exercise (UAE) and leg exercise (LE). Methods:, In six volunteer healthy subjects, we evaluated the volumes of chest wall (Vcw) and its compartments, the pulmonary apposed rib cage (Vrc,p), the diaphragm-abdomen apposed rib cage (Vrc,a) and the abdomen (Vab), by optoelectronic plethysmography. Oesophageal, gastric and trans-diaphragmatic pressures were simultaneously measured. Chest wall relaxation line allowed the measure of peak rib cage inspiratory muscle, expiratory muscle and abdominal muscle pressures. The loop Vrc,p/Vrc,a allowed the calculation of rib cage distortion. Dyspnoea was assessed by a modified Borg scale. Results:, There were some differences and similarities between UAE and LE. Unlike LE with UAE: (i) Vcw and Vrc,p at end inspiration did not increase, whereas a decrease in Vrc,p contributed to decreasing CW end expiratory volume; (ii) pressure production of inspiratory rib cage muscles did not significantly increase from quiet breathing. Not unlike LE, the diaphragm limited its inspiratory contribution to ventilation with UAE with no consistent difference in rib cage distortion between UAE and LE. Finally, changes in abdominal muscle pressure, and inspiratory rib cage muscle pressure predicted 62% and 41.4% of the variability in Borg score with UAE and LE, respectively (P < 0.01). Conclusion:, Leg exercise and UAE are associated with different patterns of CW kinematics, respiratory muscle coordination, and production of dyspnoea. [source]


    Insulin therapy in type 2 diabetes patients failing oral agents: cost-effectiveness of biphasic insulin aspart 70/30 vs. insulin glargine in the US,

    DIABETES OBESITY & METABOLISM, Issue 1 2007
    J. A. Ray
    Objectives:, To project the long-term clinical and economic outcomes of treatment with biphasic insulin aspart 30 (BIAsp 70/30, 30% soluble and 70% protaminated insulin aspart) vs. insulin glargine in insulin-naïve type 2 diabetes patients failing to achieve glycemic control with oral antidiabetic agents alone (OADs). Methods:, Baseline patient characteristics and treatment effect data from the recent ,INITIATE' clinical trial served as input to a peer-reviewed, validated Markov/Monte-Carlo simulation model. INITIATE demonstrated improvements in HbA1c favouring BIAsp 70/30 vs. glargine (,0.43%; p < 0.005) and greater efficacy in reaching glycaemic targets among patients poorly controlled on OAD therapy. Effects on life expectancy (LE), quality-adjusted life expectancy (QALE), cumulative incidence of diabetes-related complications and direct medical costs (2004 USD) were projected over 35 years. Clinical outcomes and costs were discounted at a rate of 3.0% per annum. Sensitivity analyses were performed. Results:, Improvements in glycaemic control were projected to lead to gains in LE (0.19 ± 0.24 years) and QALE (0.19 ± 0.17 years) favouring BIAsp 70/30 vs. glargine. Treatment with BIAsp 70/30 was also associated with reductions in the cumulative incidences of diabetes-related complications, notably in renal and retinal conditions. The incremental cost-effectiveness ratio was $46 533 per quality-adjusted life year gained with BIAsp 70/30 vs. glargine (for patients with baseline HbA1c , 8.5%, it was $34 916). Total lifetime costs were compared to efficacy rates in both arms as a ratio, which revealed that the lifetime cost per patient treated successfully to target HbA1c levels of <7.0% and , 6.5% were $80 523 and $93 242 lower with BIAsp 70/30 than with glargine, respectively. Conclusions:, Long-term treatment with BIAsp 70/30 was projected to be cost-effective for patients with type 2 diabetes insufficiently controlled on OADs alone compared to glargine. Treatment with BIAsp 70/30 was estimated to represent an appropriate investment of healthcare dollars in the management of type 2 diabetes. [source]


    Redefining the role of lymphocytes in gastroesophageal reflux disease and eosinophilic esophagitis

    DISEASES OF THE ESOPHAGUS, Issue 5 2010
    B. Basseri
    SUMMARY Eosinophilic esophagitis (EoE) and reflux esophagitis (RE) overlap clinically and histologically. RE is characterized by epithelial infiltration with small numbers of neutrophils and eosinophils, EoE by a prominent eosinophilic infiltrate. Lymphocytic esophagitis (LE), a new entity characterized by peripapillary lymphocytosis, questions the role lymphocytes play in esophageal inflammation. We test the hypothesis that lymphocyte infiltration in RE differs from EoE. One blinded pathologist read esophageal biopsies from 39 RE and 39 EoE patients. Both groups demonstrated significant numbers of lymphocytes (RE 22.7 ± 2.2/HPF, EoE 19.8 ± 1.8/HPF). Eosinophils/HPF in RE and EoE were 2.8 ± 0.7 and 74.9 ± 8.2, respectively (P < 0.001). Neutrophils were uncommon in RE (0.26 ± 0.16/HPF) and EoE (0.09 ± 0.04; P = 0.07). Eight of the 39 RE specimens had ,50 lymphocytes in ,1 HPF. Two were consistent with LE. There was an inverse correlation between numbers of eosinophils and lymphocytes in EoE (R = ,0.47; P = 0.002), and no correlation between them in RE (R = 0.18; P = 0.36). The patients with EoE who used antireflux medications had fewer lymphocytes (16.3 ± 1.3 vs 22.2 ± 2.3/HPF; P = 0.030) and eosinophils (55.6 ± 5.2 vs 76.0 ± 8.7/HPF; P = 0.042) than those who did not. The pathological role of lymphocytes in RE and EoE may be underestimated. Our observation that 5% of the RE specimens meet histopathological criteria for LE potentially blurs the line between these entities. The observation that eosinophil counts are lower in EoE when antireflux meds are used supports the notion that reflux plays a role in the clinical expression of EoE. [source]


    Effects of stocked trout on native fish communities in boreal foothills lakes

    ECOLOGY OF FRESHWATER FISH, Issue 2 2010

    Nasmith LE, Tonn WM, Paszkowski CA, Scrimgeour GJ. Effects of stocked trout on native fish communities in boreal foothills lakes. Ecology of Freshwater Fish 2010: 19: 279,289. © 2010 John Wiley & Sons A/S Abstract,,, Ecological effects of stocking nonnative trout into lakes are receiving increased attention, especially in alpine environments. We assessed effects of stocked trout on native forage fishes in the boreal foothills of Alberta (Canada) by comparing fish density, population size structure and spatial and temporal activities in stocked and unstocked lakes over 3 years (2005,2007). The numerically dominant dace (primarily Phoxinus spp.) were larger in stocked lakes, consistent with size-limited predation. Dace were also more crepuscular and concentrated on the lake-bottom in stocked lakes, compared to more daytime activity in the water column in unstocked lakes. There were, however, no demonstrable effects of trout on the abundance of forage fish. The lack of major population-level impacts of stocked trout suggests that current stocking practices, characteristics of boreal foothill lakes (e.g. thermal structure, abundant invertebrates, dense macrophytes) and/or behavioural adjustments of forage fish contribute to healthy native fish populations in our stocked lakes.

    Determination of iodide in samples with complex matrices by hyphenation of capillary isotachophoresis and zone electrophoresis

    ELECTROPHORESIS, Issue 20 2007
    Pavla Pant
    Abstract A method has been developed for the determination of iodide in mineral water, seawater, cooking salt, serum, and urine based on hyphenation of capillary ITP and zone electrophoresis. A commercially available instrumentation for capillary ITP with column-switching system was used. ITP served for removal of chloride present in the analyzed samples in a ratio of 106,107:1 to iodide, zone electrophoresis was used for evaluation. Isotachophoretic separation proceeded in a capillary made of fluorinated ethylene,propylene copolymer of 0.8,mm id and 90,mm total length to the bifurcation point filled with a leading electrolyte (LE) composed of 8,mM HCl,+,16,mM ,-alanine (,-Ala),+,10% PVP,+,2.86,mM N2H4×2HCl, pH,3.2; and a terminating electrolyte composed of 8,mM H3PO4,+,16,mM ,-Ala,+,10% PVP,+,5,mM N2H4, pH,3.85 for all the matrices except seawater. For ITP of seawater the LE consisted of 50,mM HCl,+,100,mM ,-Ala,+,10% PVP +,2.86,mM N2H4×2HCl, pH,3.52. Distance of conductivity detector from the injection point and bifurcation point was 52 and 38,mm, respectively. Zone electrophoresis was performed in a capillary made of fused silica of 0.3,mm id and 160,mm total length filled with LE from isotachophoretic step. LODs reached for all matrices were 2,3×10,8,M concentration (2.5,4,,g/L) enabled monitoring of iodide in all analyzed samples with RSD 0.4,9.3%. Estimated concentrations of iodide in individual matrices were 10,6,10,8,M. [source]


    Determination of trace cationic impurities in butylmethylimidazolium-based ionic liquids: From transient to comprehensive single-capillary counterflow isotachophoresis-zone electrophoresis

    ELECTROPHORESIS, Issue 23 2006
    Marek Urbánek
    Abstract Determination of impurities in ionic liquids (ILs) remains a difficult task. In this work, the hyphenation of isotachophoretic,(ITP) preconcentration to zone electrophoresis,(ZE) has been explored for the trace analysis of the cationic impurities Na+, Li+, and methylimidazolium (MI+) in butylmethylimidazolium (BMI+)-based ILs. Simultaneous detection of UV-transparent and UV-absorbing impurities was ensured by a BGE composed of creatinine-acetate buffer. To induce ITP, three different strategies were evaluated: (i),Sample self-stacking ensured by the addition of ammonium acetate (NH4Ac) to 25,50-fold diluted IL solution (transient ITP). (ii),Complete ITP-ZE separation performed in a single capillary: ITP was realized in discontinuous electrolytes comprising an 80,mM NH4Ac, 40,mM acetic acid, 30,mM ,-CD, pH,5.05, leading electrolyte,(LE) and a 10,mM creatinine, 10,mM acetic acid, pH,4.9, terminating electrolyte,(TE). To create the ZE stage, the ITP stack of analytes was moved back toward the capillary inlet by pressure and simultaneously the capillary was filled with the BGE. This protocol made it possible to accommodate a 2.5-times diluted IL sample. (iii),Complete counterflow ITP-ZE with continuous electrokinetic sample supply: the ITP stage was performed in a capillary filled with a 150,mM NH4Ac, 75,mM acetic acid, 30,mM ,-CD, pH,5.0 LE, with 40-times diluted IL at the capillary inlet. BMI+ from IL acts as the terminating ion. The LODs reached in this latter case were at the 10 and 1,ppb levels for MI+ and Li+ in diluted IL matrix, respectively. [source]


    Effect of local analgesia on movement of the equine back

    EQUINE VETERINARY JOURNAL, Issue 1 2006
    K. ROETHLISBERGER HOLM
    Summary Reasons for performing study: Diagnostic infiltration of local anaesthetic solution is commonly used in cases of equine back pain. Evaluation is subjective and it is not known how local analgesia of the back affects horses without clinical signs of back pain. Objectives: To evaluate the effect of infiltration of local anaesthetics on the movement of the back in horses without clinical signs of back pain, and to evaluate the usefulness of kinematic studies as an objective and quantitative tool in evaluating local analgesia in clinical practice. Methods: The kinematics of the back in 10 clinically sound horses were measured on 2 occasions at walk and trot before and after injections with mepivacaine and sodium chloride around the interspinous spaces between T16 and L2. The kinematics were compared between the 2 occasions before injections and before and after each injection. Results: The range of motion (ROM) for dorsoventral flexion-extension (FE) of the back was increased significantly in all measured segments other than T10 at walk, as was lateral bending (LB) at T10, L3 and L5 after injection of mepivacaine. For lateral excursion (LE), total movement increased at all measured segments. At trot the only affected segment was L3, where the injection with mepivacaine decreased the ROM for FE. After injection of sodium chloride the ROM for FE increased at T13 and T17 at walk. Lateral bending and LE were not affected at walk. At trot, LB increased at L3 and L5. Conclusions and potential relevance: Diagnostic infiltration of local anaesthetic solution affects the function of the back in clinically sound horses, which must be considered when interpreting the use of this clinical aid in assessing clinical cases of back dysfunction. Kinematics can qualitatively and quantitatively evaluate the effect of local analgesia of the back. [source]


    Prevention of hemodialysis-related muscle cramps by intradialytic use of sequential compression devices: A report of four cases

    HEMODIALYSIS INTERNATIONAL, Issue 3 2004
    Muhammad Ahsan
    Background:, Hemodialysis (HD)-related lower extremity (LE) muscle cramps are a common cause of morbidity in end-stage renal disease patients on maintenance HD. Numerous pharmacologic and physical measures have been tried with variable success rates. Methods:, Sequential compression devices (SCD) improve venous return (VR) and are commonly used to prevent LE deep venous thrombosis in hospitals. We hypothesized that LE cramps are triggered by stagnant venous flow during HD and are preventable by improving VR. We prospectively studied four adult patients (mean age 61 ± 14 years) on thrice-weekly HD who experienced two or more episodes of LE cramping weekly in the month before the study. SCD were applied before each HD on both legs and compressions were intermittently applied at 40 mmHg during treatment. Results:, All four patients reported complete resolution of cramping during the study period that lasted 1 month or 12 consecutive dialysis treatments. Conclusion:, Application of SCD to LE may prevent the generation of LE HD-related cramping in a select group of patients. Larger, controlled studies are needed to establish the utility of this noninvasive alternative for the prevention of LE HD-related cramps. [source]


    Energy budget above a temperate mixed forest in northeastern China

    HYDROLOGICAL PROCESSES, Issue 18 2007
    Jiabing Wu
    Abstract Components of the energy budget were measured continuously above a 300-year-old temperate mixed forest at the Changbaishan site, northeastern China, from 1 January to 31 December 2003, as a part of the ChinaFlux programme. The albedo values above the canopy were lower than most temperate forests, and the values for snow-covered canopy were over 50% higher than for the snow-free canopy. In winter, net radiation Rn was generally less than 5% of the summer value due to high albedo and low incoming solar radiation. The annual mean latent heat LE was 37·5 W m,2, accounting for 52% of Rn. The maximum daily evaporation was about 4·6 mm day,1 in summer. Over the year, the accumulated precipitation was 578 mm; this compares with 493 mm of evapotranspiration, which shows that more than 85% of water was returned to the atmosphere through evapotranspiration. The LE was strongly affected by the transpiration activity and increased quickly as the broadleaved trees began to foliate. The sensible heat H dropped at that time, although Rn increased. Consequently, the seasonal variation in the Bowen ratio , was clearly U-shaped, and the minimum value (0·1) occurred on a sunny day just after rain, when most of the available energy was used for evapotranspiration. Negative , values occurred occasionally in the non-growing season as a result of intensive radiative cooling and the presence of water on the surface. The , was very high (up to 13·0) in snow-covered winter, when evapotranspiration was small due to low surface temperature and available soil water. Vegetation phenology and soil moisture were the key variables controlling the available energy partitioning between H and LE. Energy budget closure averaged better than 86% on a half-hourly basis, with slightly greater closure on a daily basis. The degree of closure showed a dependence on friction velocity u*.

    Influences of meteorological and vegetational factors on the partitioning of the energy of a rice paddy field

    HYDROLOGICAL PROCESSES, Issue 8 2005
    Hiroki Oue
    Abstract Observations made in a paddy field were analysed to show the influences of meteorological and vegetational factors on the crop's energy budget. Energy budget in the paddy field was characterized by the major partitioning to latent heat flux LE and by the negative Bowen ratio B mostly in the afternoon. Canopy resistance rc, estimated with the Penman,Monteith equation, was related to the influences of solar radiation SR, vapour pressure deficit VPD and plant height. The results demonstrated that rc could not directly account for B but that critical canopy resistance rcc, defined as the canopy resistance when B = 0, could be used to standardize rc, and that rc , rcc proved to be a good parameter to account for B. Influences of bulk stomatal response on energy partitioning were assessed as follows: the Bowen ratio dropped below zero, while the bulk stomatal aperture dwindled with the increase of VPD. In addition, stomata of a big leaf acted to promote the partitioning to LE against the rise of SR in the condition of higher VPD. Copyright © 2004 John Wiley & Sons, Ltd. [source]


    Muscle performance in patients with Crohn's disease in clinical remission

    INFLAMMATORY BOWEL DISEASES, Issue 3 2005
    Jean-Baptiste Wiroth PhD
    Abstract Background: Because patients with Crohn's disease (CD) often show increased energy expenditure, nutritional deficiencies, and general fatigue, all which may persist after a flare, we hypothesized that CD could alter muscle mass and function. This study aimed to assess muscle strength and endurance in CD patients in clinical remission and the influencing factors. Methods: Forty-one outpatients (17 men and 24 women; age, 37 ± 10 yr), in remission (CD Activity Index < 150) for >3 months, and 25 age-matched healthy controls (10 men and 15 women; age, 37 ± 13 yr) were evaluated. Evaluation included a sit-up test, hand-grip strength test, hand-grip endurance test, lower limb strength test, and lower limb endurance test (LE), as well as a measure of physical activity. Results: No significant difference was found between CD and control groups regarding weight, height, body mass index, fat mass, and fat-free mass. Strength performance was lower in CD subjects compared with controls, particularly for lower limb indexes: lower limb strength test (,24.6%, P < 0.001), LE (,25.8%, P < 0.001), and sit-up test (,25.1%, P < 0.001). Previous disease severity, disease duration, the cumulative dose of glucocorticosteroids, current inflammation, and global habitual physical activity did not affect muscle performance. A recent use of steroids improved LE. Conclusions: CD patients in clinical remission have decreased muscle function that may affect their quality of life. This pattern is reflected by reduced strength and endurance indexes, particularly for lower limbs. The reasons for these changes need further study. Strength training should be assessed in these patients. [source]


    Interface reconstruction with least-square fit and split Eulerian,Lagrangian advection

    INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 3 2003
    Ruben Scardovelli
    Abstract Two new volume-of-fluid (VOF) reconstruction algorithms, which are based on a least-square fit technique, are presented. Their performance is tested for several standard shapes and is compared to a few other VOF/PLIC reconstruction techniques, showing in general a better convergence rate. The geometric nature of Lagrangian and Eulerian split advection algorithms is investigated in detail and a new mixed split Eulerian implicit,Lagrangian explicit (EI,LE) scheme is presented. This method conserves the mass to machine error, performs better than split Eulerian and Lagrangian algorithms, and it is only slightly worse than unsplit schemes. However, the combination of the interface reconstruction with the least-square fit and its advection with the EI,LE scheme appears superior to other existing approaches.

    An unusual association of pemphigus vulgaris with hyperprolactinemia

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2002
    MNAMS, Sujay Khandpur MD
    A 21-year-old unmarried woman presented with oral ulcerations and generalized, itchy, fluid-filled, skin lesions of 10 days' duration. The lesions ruptured spontaneously, resulting in extensive denuded areas covered by crusts. One month prior to this, she experienced pain and enlargement of both breasts with galactorrhea. Her menstrual cycles were normal initially, but later she developed menstrual irregularities. No past history suggestive of any other systemic or skin disease, including atopy or drug allergies, could be obtained. Her family history was not contributory. Dermatologic examination revealed multiple, flaccid bullae and extensive denuded areas of skin covered with crusts over the scalp, face, trunk, and upper and lower limbs (Fig. 1). Bulla spread sign and Nikolsky's sign were positive. The oral mucosa, including the lips, buccal surface, tongue, and palate, showed multiple erosions covered with necrotic slough. The rest of the mucocutaneous and systemic examination was within normal limits. Figure 1. Extensive erosions and flaccid bullae over the trunk with breast enlargement The patient's diagnostic work-up revealed: hemoglobin, 11.2 g%; total leukocyte count, 7400/mm3; differential leukocyte count, P62L34E2M2; erythrocyte sedimentation rate, 34 mm/h. A peripheral blood smear examination, urinalysis, blood sugar, and renal and liver function tests were normal. Venereal Disease Research Laboratory (VDRL) test and enzyme-linked immunoabsorbent assay (ELISA) for human immunodeficiency virus (HIV) were nonreactive. Antinuclear antibody, lupus erythematosus (LE) cell, rheumatoid factor, and anti-dsDNA levels were normal. Serum protein electrophoresis demonstrated increased levels of immunoglobulin G (IgG) antibody. The serum prolactin level was significantly raised to 139.49 ng/mL (normal, 3.6,18.9 ng/mL). The sex hormone levels, however, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and progesterone, were within normal limits. The thyroid hormone profile was also unaltered. Chest X-ray was normal. Ultrasound of the abdomen and pelvis revealed no visceral abnormality and computerized tomography (CT) scan of the pituitary sella showed no adenoma. Mammography was negative for breast malignancy. A Tzanck smear prepared from the base of the erosion showed multiple acantholytic cells and lymphocytes. Histologic examination from an intact vesicle was suggestive of pemphigus vulgaris (PV), showing a suprabasal cleft with acantholytic cells and the basal layer demonstrating a "row of tombstones" appearance (Fig. 2). Direct immunofluorescence (DIF) revealed the intercellular deposition of IgG and C3 throughout the epidermis in a "fishnet pattern." Indirect immunofluorescence (IIF) test performed on rat esophagus for circulating IgG antibody was positive in a titer of 1 : 120. Figure 2. Photomicrograph showing suprabasal cleft with "row of tombstones" appearance, suggestive of pemphigus vulgaris (hematoxylin and eosin, × 40) Based on the clinical and immunohistological features, a diagnosis of PV with idiopathic hyperprolactinemia was made. The patient was treated with bromocriptine mesylate (Tablet Proctinal, Glaxo Wellcome Ltd, India) at a dose of 2.5 mg twice a day. After 2 months of therapy, significant improvement in the skin lesions was observed. The existing lesions re-epithelialized with a drastic reduction in the number and distribution of new vesicles. However, no change in the mucosal erosions was noticed. IIF test demonstrated a lower antibody titer (1 : 40). The breast complaints also improved with a reduction in serum prolactin level to 6.5 ng/mL. The patient refused further treatment as she experienced nausea and dizziness with bromocriptine. After 2 weeks, the disease relapsed with the appearance of new vesicles over the forearms, abdomen, back, and thighs. She again complained of breast tenderness and galactorrhea, and the serum prolactin level was 95 ng/mL. The IgG titer increased to 1 : 120. Hence, treatment with oral prednisolone (2 mg/kg/day) and bromocriptine (2.5 mg twice a day) with an antiemetic was initiated. After 6 weeks, the skin lesions had cleared completely, the breast symptoms had improved, menses had become regular, and the prolactin level had decreased to 4 ng/mL. IIF test was negative for circulating antibody. Steroids were tapered off and maintenance therapy with bromocriptine at a dose of 2.5 mg/day was continued. [source]


    Effect of egg proteins on the quality and refrigerated storage life of chicken patties made with broiler-spent hen meat and by-products,

    INTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 5 2007
    A. Kalaikannan
    Summary The effects of whole egg powder (WEP), dried albumen (DA), dried yolk (DY) at a 1% level and liquid egg (LE) at a 3.7% level on the quality characteristics and refrigerated storage (4 ± 1 °C) stability of chicken patties made with meat and by-products of broiler-spent hens were evaluated. The addition of egg powders significantly enhanced the emulsion stability (ES) and product yield compared with control and LE. There was a marked increase in moisture content and sensory attributes by the addition of egg powders. During the refrigerated storage (4 ± 1 °C), thio-barbituric acid number (TBARS), aerobic plate count (APC) and psychrophilic count increased in all samples. Incorporation of DA and DY significantly reduced the TBARS number and APC during the storage over control. The addition of DA, DY and WEP significantly lowered the psychrophilic counts. Treated and control patties packaged in LDPE (low-density polyethylene) pouches were acceptable for 20 days and 15 days, respectively. [source]


    Subacute cutaneous lupus erythematosus with bullae associated with porphyria cutanea tarda

    JOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 3 2007
    Wiebke K. Peitsch
    Summary A 58-year-old patient presented with both annular and polycyclic as well as vesicular lesions. Histology revealed an interface dermatitis with focal hyperkeratosis and subepidermal blistering. Antinuclear antibodies were elevated (1 : 1280) and autoantibodies against Ro-SS-A were found. Based on these findings we made a diagnosis of subacute cutaneous lupus erythematosus (SCLE) with blister formation. Additionally, we diagnosed porphyria cutanea tarda (PCT) triggered by alcohol abuse. Treatment with systemic corti-costeroids and low-dose hydroxy-chloroquine led to rapid resolution of the skin changes. SCLE with blister formation is a rare cause of bullous skin eruptions and has to be distinguished from bullous autoimmune diseases as well as from bullous SLE. Recognition of concomitant PCT, which may be associated with all forms of LE, is especially important because of the therapeutic implications, since a reduced dosage of antimalarials is required.

    Laboratory and field studies on the integrated pest management of Helicoverpa armigera (Hübner) in cotton, based on pheromone trap catch threshold level

    JOURNAL OF APPLIED ENTOMOLOGY, Issue 5-6 2000
    G. V. P. Reddy
    Results revealed that egg parasitism in the laboratory by Trichogramma chilonis was 75.6%. Among the insecticides tested against T. chilonis and the predator Chrysoperla carnea, nimbecidine (neem product) and dipel resulted in zero mortality, with only a low level of mortality by dimethoate, cypermethrin, fenvalerate, alphamethrin and monocrotophos. Combinations of nimbecidine 2% + NPV at 250 larval equivalents (LE)/ha and dipel 8 l + NPV @250 LE/ha were the most effective treatments against H. armigera. The integrated pest management components (T. chilonis, C. carnea, NPV, nimbecidine, dipel and synthetic chemicals) were imposed at different intervals on the basis of pheromone trap threshold level (7 moths/trap per night) on a consolidated block of 40 ha cotton (MCU-1) fields at two locations, Shankarabanda and Korlagundi. The results demonstrated a significant superiority of the IPM strategy in terms of both cost versus benefit and environmental safety over that used in the farmer's fields where only conventional control methods were followed.

    Syzygium cumini leaf and seed extract mediated biosynthesis of silver nanoparticles and their characterization

    JOURNAL OF CHEMICAL TECHNOLOGY & BIOTECHNOLOGY, Issue 10 2010
    Vineet Kumar
    Abstract BACKGROUND: Plant mediated synthesis of metallic nanoparticles has been studied and reported, however, to date, the biomolecules involved in the synthesis of metallic nanoparticles have not been characterized. This study was therefore undertaken to characterize the biomolecules of Syzygium cumini involved in the synthesis of silver nanoparticles. RESULTS: Synthesis kinetics and morphological characterization of silver nanoparticles (SNP) synthesized using leaf extract (LE) and seed extract (SE) as well as their polar (water) fractions from Syzygium cumini were compared. The polyphenols content and high performance liquid chromatography (HPLC) profile of different fractions revealed good correlation between size and synthesis rate of SNP. SE contains more polyphenols and biochemical constituents than LE and therefore, showed higher synthesis rate and bigger sized SNP. To analyse the nature of biomolecules involved in the synthesis of SNP, LE and SE were fractionated on a polarity basis by solvent,solvent partitioning. Only the water fractions of LE and SE showed potential for SNP synthesis. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) analysis of SNP indicated that all fractions catalyze the synthesis of spherical nanoparticles. The average size of SNP synthesized by LE, leaf water fraction, SE and seed water fraction were 30, 29, 92, and 73 nm respectively. CONCLUSION: Results suggest that only highly polar soluble constituents are responsible for SNP synthesis. The size of SNP was found to be directly correlated with the amount of polyphenols as well as surfactants present in the reaction solution. Thus, the amount of polyphenols could be one of the crucial parameters determining the size and distribution of SNP. Copyright © 2010 Society of Chemical Industry [source]


    Association between level of education and oral health status in 35-, 50-, 65- and 75-year-olds

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2003
    J. Paulander
    Abstract Aim: The aim of the present study was to evaluate the association between educational level and dental disease, treatment needs and oral hygiene habits. Material and methods: Randomized samples of 35-, 50-, 65- and 75-year-olds, classified according to the educational level: [low (LE): elementary school or higher (HE)], were identified. In 1091 subjects, a number of characteristics such as (i) number of teeth, (ii) periodontal attachment levels (PAL), (iii) caries and (iv) occlusal function were recorded. Educational level, oral hygiene and dietary habits were self-reported. Non-parametric variables were analyzed by ,2, Mann,Whitney U,Wilcoxon's rank sum tests, and parametric variables by Student's t -test (level of significance 95%). A two-way anova was performed on decayed, missing and filled surfaces to investigate the interaction between age and educational level. All statistical procedures were performed in the SPSS© statistical package. Results: The number of remaining teeth was similar for LE and HE in the 35-year olds (25.8 versus 26.6), but in the older age groups LE had significantly a larger number of missing teeth. The LE groups (except in 65-year olds) exhibited significantly more PAL loss. LE had significantly fewer healthy gingival units in all but the 75-year age group. In all age groups, LE had fewer intact tooth surfaces and a significantly poorer occlusal function. The frequency of tooth cleaning measures and dietary habits did not differ between LE and HE. Conclusion: Educational level was shown to influence the oral conditions and should be considered in assessing risk, and in planning appropriate preventive measures. Zusammenfassung Ziel: Das Ziel der vorliegenden Studie war die Evaluation der Verbindung zwischen Bildungsniveau und Erkrankungen der Zähne, Behandlungsnotwendigkeit und oralen Hygienegewohnheiten. Material und Methoden: Randomisierte Gruppen von 35-, 50-, 65- und 75-Jährigen, die entsprechend ihres Bildungsniveau: niedriges Niveau (LE): Grundschule oder höheres Niveau (HE) klassifiziert wurden, wurden gebildet. Bei 1091 Personen wurden eine Anzahl von Charakteristika aufgezeichnet: (i) Anzahl der Zähne, (ii) parodontales Stützgewebeniveau (PAL), (iii) Karies, (iv) okklusale Funktion. Bildungsniveau, orale Hygiene und Eßgewohnheiten wurden selbst erfasst. Parameterfreie Variable wurden mit dem Chi-Quadrat test, dem Mann,Whitney U,Wilcoxon Rangsummentest und die parametergebundenen Variablen mit dem Student t -test (Signifikanz-Niveau 95 %) analysiert. Die Zwei-Wege ANOVA wurde auf dem DMF-s durchgeführt, um die Beziehung zwischen Alter und Bildungsniveau zu untersuchen. Alle statistischen Berechnungen wurden mit dem SPSS Statistik Programm vorgenommen. Ergebnisse: Die Anzahl der verbliebenen Zähne war zwischen LE und HE ähnlich bei den 35-Jährigen (25.8 vs. 26.6), aber in den älteren LE-Gruppen waren signifikant höhere Zahlen für fehlende Zähne. Die LE-Gruppen (ohne die 65-Jährigen) zeigten signifikant größeren PAL Verlust. LE hatten signifikant weniger gingivale Gesundheit bei den 75-Jährigen. In allen Altersgruppen hatten die LE weniger intakte Zahnoberflächen und signifikant geringere okklusale Funktion. Die Häufigkeit der Zahnreinigung und die Eßgewohnheiten unterschieden sich zwischen LE und HE nicht. Schlussfolgerung: Das Bildungsniveau hat einen Einfluss auf die oralen Bedingungen und sollte bei der Erfassung des Risikos und bei der Planung geeigneter Präventionsmaßnahmen beachtet werden. Résumé But: Le but de cette étude était d'évaluer l'association entre niveau d'éducation et maladie dentaire, besoins de traitement et habitudes d'hygiène orale. Matériel et méthodes: Des échantillons randomisés de sujets âgés de 35-, 50-, 65- et 75 ans, classés selon leur niveau d'éducation: [Bas (LE): école élémentaire, ou élevé (HE)] furent identifiés. Chez 1091 sujets, on a enregistré les caractéristiques suivantes: (i) nombre de dents, (ii) niveau d'attache parodontal (PAL), (iii) caries et (iv) fonction occlusale. Le niveau d'éducation, l'hygiène orale, et les habitudes alimentaires étaient rapportés par les patients eux-même. Les variables non paramétriques furent analysées par les tests chi carré, Mann,Whitney U,Wilcoxon rank sum, et les variables paramétriques par le test t de Student (niveau de signification 95%). 2-way ANOVA fut réalisé sur le DMFS pour rechercher l'interaction entre l'âge et le niveau d'éducation. Toutes les opérations statistiques furent menées par utilisation de SPSS©. Résultats: le nombre de dents restantesétait semblable pour LE et HE chez les sujets de 35 ans (25.8 vs. 26.6), mais dans les groupes plus âgés, LE présentait un nombre significativement plus important de dents absentes. Le groupe LE (sauf chez les patients de 65 ans) présentait plus de perte de PAL. LE présentait moins d'unités gingivales saines sauf dans le groupe de patients âgés de 75 ans. Dans tous les groupes d'âge, LE avait moins de surfaces dentaires intactes et une fonction occlusale significativement plus faible. La fréquence des mesures de nettoyage dentaire et les habitudes alimentaires n'étaient pas différentes entre les groupes LE et HE. Conclusion: Il est montré que le niveau d'éducation influence les conditions orales et cela doit être pris en considération lors de la mise en évidence du risque et dans la planification de mesures de prévention appropriées.

    Using the local elevation method to construct optimized umbrella sampling potentials: Calculation of the relative free energies and interconversion barriers of glucopyranose ring conformers in water

    JOURNAL OF COMPUTATIONAL CHEMISTRY, Issue 1 2010
    Halvor S. Hansen
    Abstract A method is proposed to combine the local elevation (LE) conformational searching and the umbrella sampling (US) conformational sampling approaches into a single local elevation umbrella sampling (LEUS) scheme for (explicit-solvent) molecular dynamics (MD) simulations. In this approach, an initial (relatively short) LE build-up (searching) phase is used to construct an optimized biasing potential within a subspace of conformationally relevant degrees of freedom, that is then used in a (comparatively longer) US sampling phase. This scheme dramatically enhances (in comparison with plain MD) the sampling power of MD simulations, taking advantage of the fact that the preoptimized biasing potential represents a reasonable approximation to the negative of the free energy surface in the considered conformational subspace. The method is applied to the calculation of the relative free energies of ,- D -glucopyranose ring conformers in water (within the GROMOS 45A4 force field). Different schemes to assign sampled conformational regions to distinct states are also compared. This approach, which bears some analogies with adaptive umbrella sampling and metadynamics (but within a very distinct implementation), is shown to be: (i) efficient (nearly all the computational effort is invested in the actual sampling phase rather than in searching and equilibration); (ii) robust (the method is only weakly sensitive to the details of the build-up protocol, even for relatively short build-up times); (iii) versatile (a LEUS biasing potential database could easily be preoptimized for small molecules and assembled on a fragment basis for larger ones). © 2009 Wiley Periodicals, Inc.

    Lupus erythematosus: clinical and histopathological study of oral manifestations and immunohistochemical profile of epithelial maturation

    JOURNAL OF CUTANEOUS PATHOLOGY, Issue 10 2006
    Silvia Vanessa Lourenço
    Background:, Lupus erythematosus (LE) is an autoimmune disease of unknown cause. Prevalence of oral involvement in patients with LE is uncertain but may vary from 9 to 45% in patients with systemic disease and from 3 to 20% in patients with chronic cutaneous involvement. Methods:, Incidence of oral lesions of LE and their clinical aspects were investigated. Their histopathologic features were analyzed, and the status of epithelial maturation was assessed through the expression patterns of cytokeratins. Results:, Twenty-six patients (from 188 examined) presented oral lesions of LE. Most of them were females (19) with systemic disease (11). Clinical aspects of these lesions varied, and lips and buccal mucosa were most affected. Histologically, lesions revealed lichenoid mucositis with perivascular infiltrate and thickening of basement. Cytokeratins profile showed hyperproliferative epithelium, with expression of CK5/6, and CK14 on all epithelial layers, CK16 on all suprabasal layers and CK10 on prickle cell layers only. Conclusions:, Oral lesions of LE show a variety of aspects, and their microscopic features are of a lichenoid mucositis with deep inflammatory infiltrate. Cytokeratins expression patterns are of hyperproliferative epithelium, and this phenomenon must be analyzed in relation to the inflammatory cytokines for a better understanding of the mechanisms of the disease.

    Scarring alopecia and the dermatopathologist

    JOURNAL OF CUTANEOUS PATHOLOGY, Issue 7 2001
    Leonard C. Sperling
    Background: The evaluation of patients with cicatricial alopecia is particularly challenging, and dermatopathologists receive little training in the interpretation of scalp biopsy specimens. Accurate interpretation of specimens from patients with hair disease requires both qualitative (morphology of follicles, inflammation, fibrosis, etc.) and quantitative (size, number, follicular phase) information. Much of this data can only be obtained from transverse sections. In most cases, good clinical/pathologic correlation is required, and so clinicians should be expected to provide demographic information as well as a brief description of the pattern of hair loss and a clinical differential diagnosis. Results: The criteria used to classify the various forms of cicatricial alopecia are relatively imprecise, and so classification is controversial and in a state of evolution. There are five fairly distinctive forms of cicatricial alopecia: 1) chronic, cutaneous lupus erythematosus (discoid LE); 2) lichen planopilaris; 3) dissecting cellulitis (perifolliculitis abscedens et suffodiens); 4) acne keloidalis; and 5) central, centrifugal scarring alopecia (follicular degeneration syndrome, folliculitis decalvans, pseudopelade). Not all patients with cicatricial alopecia can be confidently assigned to one of these five entities, and "cicatricial alopecia, unclassified" would be an appropriate label for such cases. Conclusion: The histologic features of five forms of cicatricial alopecia are reviewed. Dermatopathologists can utilize a "checklist" to catalog the diagnostic features of scalp biopsy specimens. In many, but not all, cases the information thus acquired will "match" the clinical and histologic characteristics of a form of cicatricial alopecia. However, because of histologic and clinical overlap between the forms of cicatricial alopecia, a definitive diagnosis cannot always be rendered. [source]


    The cutaneous pathology of lupus erythematosus: a review

    JOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2001
    A. Neil Crowson
    The presentation of lupus erythematosus (LE) ranges from a skin rash unaccompanied by extracutaneous stigmata to a rapidly progressive lethal multiorgan disease. The diagnosis and subclassification is traditionally based on the correlation of serological and clinical findings. The latter include a photoinduced skin rash, arthralgia, arthritis, fever, Raynaud's phenomenon, anemia, leukopenia, serositis, nephritis and central nervous sysdtem disease. The conventional classification scheme includes systemic, subacute cutaneous and discoid LE. Recent advances in our understanding of the cutaneous histopathology which correlates with the traditional forms of LE, along with certain novel LE subtypes, are the focus of this review. In addition to the main subtypes of LE, we will discuss associated vasculopathic lesions and the contribution of immunofluorescence microscopy to the diagnosis of LE and related connective tissue disease syndromes. Consideration will be given to unusual variants of LE such as anti-Ro/SSA-positive systemic lupus erythematosus (SLE), bullous SLE, lymphomatoid LE, lupus erythematosus profundus, drug induced LE, linear cutaneous LE, chiblains LE and parvovirus B19-associated LE.

    Limbic Encephalitis Investigated by 18FDG-PET and 3D MRI

    JOURNAL OF NEUROIMAGING, Issue 1 2001
    Jan Kassubek MD
    ABSTRACT Two patients with clinically probable or possible limbic encephalitis (LE) are reported, both cases with typical findings in clinical symptoms (severe neuropsychological deficits and complex partial seizures) and in routine magnetic resonance imaging (MRI) (hyperintense mesiotemporal lesions). Underlying malignancy was identified (rectal carcinoma) in one case but could not be detected in the other patient. The 2 patients were investigated by cerebral 18F-fluoro-2-deoxy-D-glucose,positron emission tomography (FDG-PET) and 3-dimensional (3D) MRI, and abnormalities in metabolic activity were mapped using coregistration of spatially normalized PET and MRI. Highly significant focal hypermetabolism in bilateral hippocampal areas was found in both cases. The authors' findings support FDG-PET coregistered to 3D MRI as a potentially valuable additional tool in the imaging diagnostics of LE. Results are discussed with respect to the clinical symptoms and previously reported imaging findings in the disease. [source]


    Oral manifestations of systemic and cutaneous lupus erythematosus in a Venezuelan population

    JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 9 2007
    Jeaneth López-Labady
    Background:, The aim of this study was to characterize oral lesions in patients with systemic and cutaneous lupus erythematosus (LE) in a Venezuelan group. Methods:, Ninety patients with LE were studied. Oral biopsies were taken from patients who showed oral mucosal involvement. Tissue samples were investigated with histology and direct immunofluorescence techniques for the presence of immunoglobulins G, M, A and complement factor C3. Results:, In 90 patients with LE, 10 patients showed oral lesions related to the disease. Sixteen lesions were investigated. Oral ulcerations accompanied by white irradiating striae occurred in five patients, erythema was observed in five patients and a white homogeneous plaque in one patient. Fifteen lesions demonstrated vacuolar basal degeneration and 12 thickening of the basement membrane histologically. Direct immunofluorescence was negative in three samples. Conclusions:, These findings corroborated that ulcers are not the only manifestation of LE in the oral mucosa. Clinical and histological examinations are significant as immunoproteins are not always found on the oral sample. [source]


    Pharmacokinetics of the sequential metabolites of loteprednol etabonate in rats

    JOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 3 2008
    Whei-Mei Wu
    Pharmacokinetics, metabolism and excretion of two sequential inactive metabolites of the soft corticosteroid loteprednol etabonate (LE), ,1 -cortienic acid etabonate (AE) and ,1 -cortienic acid (A), have been investigated in rats. Pharmacokinetic studies (two-compartment model, 10 mg kg,1 intravenous bolus of AE or A) found the elimination of both AE (t1/2(,), 12.46 ± 1.18 min; CLtotal, 101.94 ± 5.80 mL min,1 kg,1; and Kel, 0.24 ± 0.02 min,1) and A (t1/2(,), 14.62 ± 0.46 min; CLtotal, 53.80 ± 1.40 mL min,1 kg,1; and Kel, 0.18 ± 0.02 min,1) to be significantly faster than that previously determined for the parent LE (t1/2(,), 43.41 ± 7.58 min; CLtotal, 67.40 ± 11.60 mL min,1 kg,1; and Kel, 0.071 ± 0.024 min,1). For metabolism and excretion evaluations, 1 and 10 mg kg,1 of either AE or A were intravenously administered, and the urine and bile were collected. AE and A rapidly reached their peak concentrations in the bile and urine, and most of them were eliminated within one hour. Total cumulative excretions at 4 h after 1 and 10 mg kg,1 injections were 85.51 ± 3.38% and 67.50 ± 2.67% for AE, and 71.90 ± 3.72% and 37.73 ± 2.69% for A in bile; and 4.84 ± 1.87% and 13.85 ± 3.27% for AE, and 24.28 ± 8.44% and 22.35 ± 1.12% for A in urine, respectively. After AE administration, the excretion of AE was > 90%, and A was < 10% in all cases, indicating that the elimination of AE was much faster than its metabolism (to A). In a manner similar to that seen for LE, dose-dependent elimination was observed both in AE and A. These results suggested that both AE and A were ideal leads for the design of soft steroids based on the inactive metabolite approach. [source]


    Suppression of Heavy Drinking and Alcohol Seeking by a Selective ALDH-2 Inhibitor

    ALCOHOLISM, Issue 11 2009
    Maria P. Arolfo
    Background:, Inherited human aldehyde dehydrogenase 2 (ALDH-2) deficiency reduces the risk for alcoholism. Kudzu plants and extracts have been used for 1,000 years in traditional Chinese medicine to treat alcoholism. Kudzu contains daidzin, which inhibits ALDH-2 and suppresses heavy drinking in rodents. Decreased drinking due to ALDH-2 inhibition is attributed to aversive properties of acetaldehyde accumulated during alcohol consumption. However, daidzin can reduce drinking in some rodents without necessarily increasing acetaldehyde. Therefore, a selective ALDH-2 inhibitor might affect other metabolic factors involved in regulating drinking. Methods:, Aldehyde dehydrogenase 2 inhibitors were synthesized based on the co-crystal structure of ALDH-2 and daidzin. We tested the efficacy of a highly selective reversible ALDH-2 inhibitor, CVT-10216, in models of moderate and high alcohol drinking rats. We studied 2-bottle choice and deprivation-induced drinking paradigms in Fawn Hooded (FH) rats, operant self-administration in Long Evans (LE), FH, and inbred P (iP) rats and in cue-induced reinstatement in iP rats. We also assayed blood acetaldehyde levels as well as dopamine (DA) release in the nucleus accumbens (NAc) and tested possible rewarding/aversive effects of the inhibitor in a conditioned place preference (CPP) paradigm. Results:, CVT-10216 increases acetaldehyde after alcohol gavage and inhibits 2-bottle choice alcohol intake in heavy drinking rodents, including deprivation-induced drinking. Moreover, CVT-10216 also prevents operant self-administration and eliminates cue-induced reinstatement of alcohol seeking even when alcohol is not available (i.e., no acetaldehyde). Alcohol stimulates DA release in the NAc, which is thought to contribute to increased drinking and relapse in alcoholism. CVT-10216 prevents alcohol-induced increases in NAc DA without changing basal levels. CVT-10216 does not show rewarding or aversive properties in the CPP paradigm at therapeutic doses. Conclusion:, Our findings suggest that selective reversible ALDH-2 inhibitors may have therapeutic potential to reduce excessive drinking and to suppress relapse in abstinent alcoholics. [source]


    Neo-Hymesian linguistic ethnography in the United Kingdom

    JOURNAL OF SOCIOLINGUISTICS, Issue 5 2007
    Ben Rampton
    This paper describes the development of ,linguistic ethnography' in Britain over the last 5,15 years. British anthropology tends to overlook language, and instead, the U.K. Linguistic Ethnography Forum (LEF) has emerged from socio- and applied linguistics, bringing together a number of formative traditions (inter alia, Interactional Sociolinguistics, New Literacy Studies and Critical Discourse Analysis). The career paths and the institutional positions of LEF participants make their ethnography more a matter of getting analytic distance on what's close-at-hand than a process of getting familiar with the strange. When linked with post-structuralism more generally, this ,from-inside-outwards' trajectory produces analytic sensibilities tuned to discourse analysis as a method, doubtful about ,comprehensive' and ,exotic' ethnography, and well disposed to practical/political intervention. LE sits comfortably in the much broader shift from mono- to inter-disciplinarity in British higher education, though the inter-disciplinary environment makes it hard to take the relationship between linguistics and ethnography for granted.

    Supplier Evaluation and Rationalization via Data Envelopment Analysis: An Empirical Examination

    JOURNAL OF SUPPLY CHAIN MANAGEMENT, Issue 3 2001
    Ram Narasimhan
    SUMMARY Strategic evaluation of supplier performance assists firms in improving their operations across a variety of dimensions. Specifically, it aids in supplier process improvement, which in turn enhances firm performance, allows for optimal allocation of resources for supplier development programs, and assists managers in restructuring their supplier network based on performance. In order to address these issues, this article proposes a methodology for effective supplier performance evaluation based on data envelopment analysis (DEA), a multi-factor productivity analysis technique. The efficiencies derived from the DEA model are utilized in conjunction with managerial performance ratings in identifying supplier clusters, which are categorized into high performers and efficient (HE), high performers and inefficient (HI), low performers and efficient (LE), and low performers and inefficient (LI). Effective benchmarks from the HE cluster are identified for improving the operations of suppliers in the HI, LE, and LI clusters. Finally, managerial insights and implications from the study are discussed. [source]

    CE ARTICLE: Recognizing and treating upper extremity lymphedema in postmastectomy/lumpectomy patients: A guide for primary care providers

    JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 9 2010
    Eva Quirion MSN
    Abstract Purpose: To provide an overview of the lymphatics, physiology of lymphedema (LE), incidence, risks, and costs as well as a guide for the primary care provider on how to recognize the symptoms of LE, a review of current published treatment recommendations, and advice about making a referral to appropriate LE specialists. Data sources: Selected studies on diagnosing and treating LE in breast cancer patients following mastectomy/lumpectomy and evidence-based treatment guidelines. Conclusions: LE is the most common complication related to breast cancer treatment with an occurrence estimated between 10% and 60% depending on the parameters used for measurement. Most commonly, LE occurs within the first 3 years after breast cancer treatment, but the remaining cases happen beyond this period of time and can occur after many years. This means that significant numbers of patients with LE can present to primary care clinicians. Implications for practice: A patient who is treated for breast cancer will be followed for a time by the oncology team, but eventually, that patient will be discharged from the oncology practice and will be seen in primary care. Risk factors for developing LE include treatment-related (number of nodes removed and radiation to axilla), disease-related (stage and location of tumor), and patient-related (younger age, obesity, and comorbid conditions) factors. A systematic evaluation of any patient presenting with LE will assure accurate diagnosis and prompt treatment. [source]
