Sample records for burning mouth syndrome-significance

  1. [Burning mouth syndrome (glossalgia)]. (United States)


    Burning mouth syndrome (glossalgia) is manifested by oral pin and tingling sensations, numbness and even burning and severe pains, more frequently in the tongue. Unpleasant sensations may involve the anterior two thirds of the tongue or be extended to the front part of the hard palate and the mucous membrane of the lower lip. This condition is characterized by "mirror" and "food dominant" symptoms, disordered salivation, dysgeusia, or psychological disorders. The disease shows a chronic course. Its etiology may be multifactorial. There are no universally accepted diagnostic criteria; the diagnosis of glossalgia is made to rule out all other causes. A thorough examination should be conducted to establish a differential diagnosis. Glossalgia occurs primarily in middle-aged and elderly people. Women get sick much more frequently than men of the same age. Glossalgia remains difficult to treat. Continuous symptomatic treatment and follow-up help relieve its symptoms.

  2. Ciguatera neurotoxin poisoning mimicking burning mouth syndrome. (United States)

    Heir, Gary M


    Burning mouth syndrome is a condition in which the patient perceives a sensation of intraoral burning, typically of the anterior tongue. This article presents a case report of a patient presenting for orofacial pain evaluation in whom ciguatera neurotoxin poisoning is diagnosed. The clinician should be aware of neurotoxin poisoning as a possible cause of symptoms of burning mouth, especially among patients who have recently traveled to a tropical area. Recognition of this condition in this case highlights the need for a detailed and accurate patient history.

  3. Burning mouth syndrome: a review and update. (United States)

    Silvestre, Francisco J; Silvestre-Rangil, Javier; López-Jornet, Pía


    Burning mouth syndrome (BMS) is mainly found in middle aged or elderly women and is characterized by intense burning or itching sensation of the tongue or other regions of the oral mucosa. It can be accompanied by xerostomia and dysgeusia. The syndrome generally manifests spontaneously, and the discomfort is typically of a continuous nature but increases in intensity during the evening and at night. Although BMS classically has been attributed to a range of factors, in recent years evidence has been obtained relating it peripheral (sensory C and/or trigeminal nerve fibers) or central neuropathic disturbances (involving the nigrostriatal dopaminergic system). The differential diagnosis requires the exclusion of oral mucosal lesions or blood test alterations that can produce burning mouth sensation. Patient management is based on the avoidance of causes of oral irritation and the provision of psychological support. Drug treatment for burning sensation in primary BMS of peripheral origin can consist of topical clonazepam, while central type BMS appears to improve with the use of antidepressants such as duloxetine, antiseizure drugs such as gabapentin, or amisulpride.

  4. Burning mouth syndrome: pathogenic and therapeutic concepts

    Directory of Open Access Journals (Sweden)

    Ferensztajn, Ewa


    Full Text Available Burning mouth syndrome (BMS is a chronic pain condition characterized by pain, burning sensations and dryness within an oral mucosa, without any clinical changes of the latter. It occurs approximately seven times more frequently in women, mostly in perimenopausal age. The psychiatric aspect of BMS is significant: the most frequent co-morbidities are depression and anxiety disorders, and a number of psychotropic drugs play an essential role in its treatment. In the present review, the most important pathogenic and treatment concepts of BMS have been discussed. The BMS may be similar to neuropathic pain and has some related pathogenic elements with fibromyalgia and the restless leg syndrome. In primary BMS, the features of presynaptic dysfunction of dopaminergic neurons and deficiency of endogenous dopamine levels have been demonstrated. Other neurotransmitters such as serotonin, noradrenaline, histamine as well as hormonal and inflammatory factors may also play a role in the pathogenesis of BMS. In the pharmacological treatment of BMS a variety of drugs have been used including benzodiazepines, anticonvulsants, antidepressants and atypical antipsychotic drugs. In the final part of the paper, the possibility of using atypical antipsychotic drug, olanzapine, in the treatment of BMS has been discussed. In the context of the recent studies on this topic, a case of female patient with the BMS lasting more than ten years has been mentioned, in whom the treatment with olanzapine brought about a rapid and significant reduction of symptoms. The probable mechanism of the therapeutic effect of olanzapine in BMS can include its effect on dopaminergic receptors and probably also on histaminergic, noradrenergic and serotonergic ones.

  6. Burning mouth syndrome associated with varicella zoster virus. (United States)

    Nagel, Maria A; Gilden, Don


    We present two cases of burning mouth syndrome (BMS)-of 8-month duration in a 61-year-old woman and of 2-year duration in a 63-year-old woman-both associated with increased levels of antivaricella zoster virus (VZV) IgM antibodies in serum and with pain that improved with antiviral treatment. Combined with our previous finding of BMS due to herpes simplex virus type 1 (HSV-1) infection, we recommend evaluation of patients with BMS not only for VZV or HSV-1 DNA in the saliva, but also for serum anti-VZV and anti-HSV-1 IgM antibodies. Both infections are treatable with oral antiviral agents.

    Miriam Grushka


    Full Text Available Burning Mouth Syndrome (BMS is a sensory disorder which results in constant, bilateral burning pain of the tongue, lips, and other oral mucous membranes. Atypical odontalgia (AO is another sensory disorder, usually defined as a toothache-like pain for which no dental cause can be identified. Previous literature has suggested that AO is often associated with a concomitant temporomandibular disorder (TMD. This hypothesis paper explores the possibility that BMS, AO and TMD can be related through hyperactivity of both the sensory and motor components of the trigeminal nerve following loss of central inhibition as a result of taste damage in the chorda tympani and/or the glossopharyngeal nerves.

    Burning mouth syndrome is characterized by altered sensory qualities, namely tongue pain hypersensitivity. We found that the mRNA expression of Artemin (Artn) in the tongue mucosa of patients with burning mouth syndrome was significantly higher than that of control subjects, and we developed a mouse model of burning mouth syndrome by application of 2,4,6-trinitrobenzene sulfonic acid (TNBS) diluted with 50% ethanol to the dorsum of the tongue. TNBS treatment to the tongue induced persistent, week-long, noninflammatory tongue pain and a significant increase in Artn expression in the tongue mucosa and marked tongue heat hyperalgesia. Following TNBS treatment, the successive administration of the transient receptor potential vanilloid 1 (TRPV1) antagonist SB366791 or neutralizing anti-Artn antibody completely inhibited the heat hyperalgesia. The number of glial cell line-derived neurotrophic factor family receptor α3 (GFRα3)-positive and TRPV1-positive trigeminal ganglion (TG) neurons innervating the tongue significantly increased following TNBS treatment and was significantly reduced by successive administration of neutralizing anti-Artn antibody. The capsaicin-induced current in TG neurons innervating the tongue was enhanced following TNBS treatment and was inhibited by local administration of neutralizing anti-Artn antibody to the tongue. These results suggest that the overexpression of Artn in the TNBS-treated tongue increases the membrane excitability of TG neurons innervating the tongue by increasing TRPV1 sensitivity, which causes heat hyperalgesia. This model may be useful for the study of tongue pain hypersensitivity associated with burning mouth syndrome.

    Burning mouth syndrome (BMS) is a relatively common disease that can severely affect the quality of life of the patient. It causes chronic orofacial pain or oral burning sensation even in the absence of any detectable organic cause. The etiology of BMS is complex and multifactorial. It has been associated with menopause, trigger events and even genetic polymorphisms. Although its etiology remains unclear, there is still much evidence that psychological elements like stress, anxiety or depression do play a significant role. There are several studies in the literature which only report the association of BMS with psychological factors. But to the best of our knowledge, there is no such case reported in the literature which has actually highlighted the management of such a case with psychogenic elements involved. In this case report, apart from discussing the role of psychological factors, the treatment of BMS with emphasis on counseling is also emphasized. Further, it is of interest to know that such patients with psychologically induced burning mouth syndrome have to be evaluated to their deepest details. Even their commonly overlooked gestures and habits like watching a particular television soap opera may be involved in their disease process. It can be concluded that psychological counseling in general dental practice can provide an effective cure for chronic oral burning sensation with psychological factors involved.

  18. Burning mouth syndrome – a common dental problem in perimenopausal women

    Directory of Open Access Journals (Sweden)

    Zuzanna Ślebioda


    Full Text Available Burning mouth syndrome (BMS is characterized by the presence of burning, paresthesia or pain of the oral mucosa in the absence of pathologic lesions revealed during the clinical examination [1-3]. Moreover, the pain may be accompanied by oral dryness, hypersensitivity to some food compounds and taste disorders [4-6]. Etiopathogenesis of this condition remains unclear. Potential local causative factors include among the others mechanical irritation, parafunctions and dysfunctions of the stomatognathic system, contact allergy to dental materials and electro-galvanic phenomena. Potential systemic causes include diabetes mellitus, B group vitamin deficiency (vitamins B1, B2, B6 and B12, folic acid and iron deficiency, hormonal imbalance, gastrointestinal diseases, psychiatric and neurological disorders and drug-induced side effects. The hypothesis concerning the role of hormonal changes in the development of BMS seems to be confirmed by a high incidence of this condition in perimenopausal women [2, 7, 8]. Up to now, due to an unclear etiology of the disease, the treatment is very often ineffective and mainly symptomatic, which may exacerbate patient’s anxiety and discomfort. In this paper we present the main etiologic factors of the burning mouth syndrome. We discuss the basic diagnostic and therapeutic methods and the influence of hormonal replacement therapy on the course of BMS based on the current medical reports.

  19. Grey matter changes of the pain matrix in patients with burning mouth syndrome. (United States)

    Sinding, Charlotte; Gransjøen, Anne Mari; Schlumberger, Gina; Grushka, Miriam; Frasnelli, Johannes; Singh, Preet Bano


    Burning mouth syndrome (BMS) is characterized by a burning sensation in the mouth, usually in the absence of clinical and laboratory findings. Latest findings indicate that BMS could result from neuropathic trigeminal conditions. While many investigations have focused on the periphery, very few have examined possible central dysfunctions. To highlight changes of the central system of subjects with BMS, we analysed the grey matter concentration in 12 subjects using voxel-based morphometry. Data were compared with a control group (Ct). To better understand the brain mechanisms underlying BMS, the grey matter concentration of patients was also compared with those of dysgeusic patients (Dys). Dysgeusia is another oral dysfunction condition, characterized by a distorted sense of taste and accompanied by a reduced taste function. We found that a major part of the 'pain matrix' presented modifications of the grey matter concentration in subjects with BMS. Six regions out of eight were affected [anterior and posterior cingulate gyrus, lobules of the cerebellum, insula/frontal operculum, inferior temporal area, primary motor cortex, dorsolateral pre-frontal cortex (DLPFC)]. In the anterior cingulate gyrus, the lobules of the cerebellum, the inferior temporal lobe and the DLPFC, pain intensity correlated with grey matter concentration. Dys also presented changes in grey matter concentration but in different areas of the brain. Our results suggest that a deficiency in the control of pain could in part be a cause of BMS and that BMS and dysgeusia conditions are not linked to similar structural changes in the brain.

  20. Potential protein biomarkers for burning mouth syndrome discovered by quantitative proteomics (United States)

    Ji, Eoon Hye; Diep, Cynthia; Liu, Tong; Li, Hong; Merrill, Robert; Messadi, Diana


    Burning mouth syndrome (BMS) is a chronic pain disorder characterized by severe burning sensation in normal looking oral mucosa. Diagnosis of BMS remains to be a challenge to oral healthcare professionals because the method for definite diagnosis is still uncertain. In this study, a quantitative saliva proteomic analysis was performed in order to identify target proteins in BMS patients’ saliva that may be used as biomarkers for simple, non-invasive detection of the disease. By using isobaric tags for relative and absolute quantitation labeling and liquid chromatography-tandem mass spectrometry to quantify 1130 saliva proteins between BMS patients and healthy control subjects, we found that 50 proteins were significantly changed in the BMS patients when compared to the healthy control subjects (p ≤ 0.05, 39 up-regulated and 11 down-regulated). Four candidates, alpha-enolase, interleukin-18 (IL-18), kallikrein-13 (KLK13), and cathepsin G, were selected for further validation. Based on enzyme-linked immunosorbent assay measurements, three potential biomarkers, alpha-enolase, IL-18, and KLK13, were successfully validated. The fold changes for alpha-enolase, IL-18, and KLK13 were determined as 3.6, 2.9, and 2.2 (burning mouth syndrome vs. control), and corresponding receiver operating characteristic values were determined as 0.78, 0.83, and 0.68, respectively. Our findings indicate that testing of the identified protein biomarkers in saliva might be a valuable clinical tool for BMS detection. Further validation studies of the identified biomarkers or additional candidate biomarkers are needed to achieve a multi-marker prediction model for improved detection of BMS with high sensitivity and specificity.

    NM Bakhshan


    Full Text Available Introduction: Burning mouth syndrome is characterized by an oral burning sensation , usually in the absence of clinical and laboratory findings. BMS is estimated to involve 1 to 5% of the adult population and is mostly reported within middle-aged women. The etiology of this disease is not thoroughly identified yet and there is a debate over the significance of Psychological factors in creating BMS. This study intended to examine the relationship between psychological factors with pain reports and psychosocial profiles of BMS patients to determine whether psychological factors are related to pain reports and burning mouth of patients. Therefore frequencies of psychological factors were analyzed. Methods: 30 patients with BMS participated in this study. They were homogenous regarding age, sex with the control group. In addition, education was possibly homogenized. The participants completed SCL-90 questionnaire for their anxiety, depression, somatic and psychotic symptoms to be scrutinized. Then, t-test was applied to analyze the research data. Results: Mean of anxiety(case20/8, control 9/53, depression(case 26/53, control 13/40, somatic(case 23/7, control 15/26 and psychotic(case 19/60, control 8/10 symptoms were higher in BMS group rather than in control groups. T-test results indicated there was no statically significant difference between BMS and control group in regard to psychological symptoms(p< 0.0001. Conclusion: The study findings indicate that psychological disorders may predispose the patients to the development of BMS.

Type II diabetes was observed in 36% of the patients and 37.1% suffered from respiratory disease,23.6% from gastritis, 15.7% from liver diseases, 30.3% from renal disease, 40.4% fromhypertension and 43.8% had sleep disorders. Also, 52.8% revealed seasonal allergy,32.6% had temporomandibular joint disorders and 59.6% had poor oral hygiene.Conclusion: BMS is a complex and multifactorial disease process in which numerous possible etiologies must be eliminated before the proper treatment can be initiated.

  4. Co-occurrence of Pain Symptoms and Somatosensory Sensitivity in Burning Mouth Syndrome: A Systematic Review (United States)

    Moisset, Xavier; Calbacho, Valentina; Torres, Pilar; Gremeau-Richard, Christelle; Dallel, Radhouane


    Background Burning mouth syndrome (BMS) is a chronic and spontaneous oral pain with burning quality in the tongue or other oral mucosa without any identifiable oral lesion or laboratory finding. Pathogenesis and etiology of BMS are still unknown. However, BMS has been associated with other chronic pain syndromes including other idiopathic orofacial pain, the dynias group and the family of central sensitivity syndromes. This would imply that BMS shares common mechanisms with other cephalic and/or extracephalic chronic pains. The primary aim of this systematic review was to determine whether BMS is actually associated with other pain syndromes, and to analyze cephalic and extracephalic somatosensory sensitivity in these patients. Methods This report followed the PRISMA Statement. An electronic search was performed until January 2015 in PubMed, Cochrane library, Wiley and ScienceDirect. Searched terms included “burning mouth syndrome OR stomatodynia OR glossodynia OR burning tongue OR oral burning”. Studies were selected according to predefined inclusion criteria (report of an association between BMS and other pain(s) symptoms or of cutaneous cephalic and/or extracephalic quantitative sensory testing in BMS patients), and a descriptive analysis conducted. Results The search retrieved 1512 reports. Out of these, twelve articles met criteria for co-occurring pain symptoms and nine studies for quantitative sensory testing (QST) in BMS patients. The analysis reveals that in BMS patients co-occurring pain symptoms are rare, assessed by only 0.8% (12 of 1512) of the retrieved studies. BMS was associated with headaches, TMD, atypical facial pain, trigeminal neuralgia, post-herpetic facial pain, back pain, fibromyalgia, joint pain, abdominal pain, rectal pain or vulvodynia. However, the prevalence of pain symptoms in BMS patients is not different from that in the age-matched general population. QST studies reveal no or inconsistent evidence of abnormal cutaneous cephalic

    Full Text Available Objective: To determine the epidemiological profile of elderly women with burning mouth symptoms. Methods: A cross sectional, quantitative, exploratory and descriptive study conducted in two phases: a determining the prevalence of burning mouth symptoms among 263 elderly women aged between 60 and 83 years who attended six public municipal community centers in Fortaleza-CE, Brazil, b defining the epidemiological profile of respondents with burning mouth symptoms, through the variables: self-reported diseases, salivary flow, use of medications, dental prosthesis and oral hygiene habits. Data were organized by the Statistical Package for Social Sciences - SPSS version 15. Results: The prevalence of burning mouth symptoms in the group was 19% (n=50. Of these, 41 (82.0% reported the manifestation of the symptoms as a scalding sensation. Regarding the occurrence, the most referred sites were: tongue (48%; n=24 and gums (22%; n=11. Among elderly women, 24 (48.0% had daily symptoms. Regarding self-reported diseases and habits: 80.0% cited cardiovascular diseases, 74.0% (n=37 musculoskeletal illness and 62.0% (n=31 neurological disorders, besides 56.0% (n=28 present reduction of salivary flow; 70.0% (n=35 took medication, 66.0% (n=33 were users of dental prosthesis and 18.0% (n=9 did not brush their teeth. Conclusions: The prevalence of burning mouth symptoms in this group was 19%; scalding sensation was the main manifestation of the symptom and the tongue was the site of major symptomatology. The epidemiological profile of symptomatic elderly was distinguished by self-reported diseases and habits such as cardiovascular, musculoskeletal and neurological disorders, in addition to reduced salivary flow, as well as the use of medications and dental prosthesis.

    Vanessa Juliana Gomes CARVALHO

    Full Text Available Abstract Introduction Burning Mouth Syndrome (BMS is a condition characterized by burning symptom of the oral mucosa in the absence of clinical signs. Its etiology is still unknown and, and to date there is no effective treatment. Purpose The aim of this study was to evaluate patients with BMS profile and the therapies results in a retrospective study. Material and method Clinical and therapeutic data were collected from records of patients with BMS diagnosed between January 2013 to April 2015 at the Clinic of Stomatology Clinic, Faculdade de Odontologia of Universidade de São Paulo, according to the criteria established by the International Headache Society in 2013. The therapies used for BMS control were also evaluated. Result Twelve patients were diagnosed with BMS at this period. All of them were women with a mean age of 61.18 years and the apex of the tongue was the most common affected site and the duration of the burning sensation ranged from 6 months to 25 years. Many therapies were prescribed for BMS control, such as topical capsaicin, topical clonazepan, low level laser therapy and homeopathy. Among the established therapies, capsaicin has immediate effect in reducing symptoms. Conclusion The present study showed that the challenges towards an effective treatment for BMS are varied and are mainly related to the lack knowing of the pathogenesis of this disease. The demographic profile of patients studied here was similar to that described in the available literature, however, the variables represented by secondary symptoms (medical history, anxiety and depression levels may be modifying factors of therapeutic response and the pathogenesis of the disease itself.

    Full Text Available El síndrome de la boca ardiente (SBA es una entidad nosológica, más frecuente en mujeres menopáusicas. Su principal característica es una sintomatología urente y/o dolorosa de la mucosa bucal (principalmente en la lengua, sin hallazgos clínicos aparentes que expliquen la aparición de esta sensación. Se encuentra relacionado con una serie de factores locales y sistémicos posibles desencadenantes, por lo que se considera de etiología multifactorial. El tratamiento va dirigido a mejorar la sintomatología y controlar los factores. Las terapias propuestas consistentes en control de factores locales, factores sistémicos y psicológicos y algunas indicaciones farmacológicas, proporcionan resultados mediocres. En términos generales, el SBA continúa siendo objeto de estudios en el ámbito de la medicina bucal en busca de un diagnóstico más preciso y de una terapéutica más eficaz.Burning mouth syndrome (BMS is a nosological entity, frequent in women in the menopausal period, which principal characteristic is a burning and/or pain sensation of the oral cavity (principally in the tongue. However, the oral mucosa often appears normal, with no apparent organic cause to account for the symptomatology. This syndrome is found to be related which a series of local and systemic factors as possible cause. Therefore is to be considerate a pathology with multifactorial etiology. The treatment is directed to improve the symptomatology and to control the factors. The proposal therapies, related to the control of local, systemic and psychological factors and some pharmacological indications, provide poor results. In general terms the BMS is still the object of many studies in the environment of the oral medicine, in order to search several aspects of diagnose and a more effective therapy.

    Full Text Available Abstract The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS. Thirty BMS subjects were randomized into two groups – Laser (LG and Placebo (CG. Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG. Each patient received 4 irradiations (laser or placebo twice a week, for two consecutive weeks (blinded to the type of irradiation received. Infrared laser (AsGaAI irradiations were applied to the affected mucosa in scanning mode, wavelength of 790 nm, output power of 20 mW and fluence of 6 J/cm2. A visual analogue scale (VAS was used to assess the therapeutic effect before and after each irradiation, and at all the control time periods: 7, 14, 30, 60 and 90 days after the last irradiation. One researcher delivered irradiation and another recorded the results. Both researchers were blinded, the first to the results, and the second to the type of radiation applied. The results were categorized according to the percentage of symptom level variation, and showed a statistically better response in LG in only two categories of the control checkpoints (p=0.02; Fisher’s Exact Test. According to the protocol used in this study, low intensity laser therapy is as beneficial to patients with BMS as placebo treatment, indicating a great emotional component of involvement in BMS symptomatology. Nevertheless, there were positive results in some statistical analyses, thus encouraging further research in BMS laser therapy with other irradiation parameters.

    Full Text Available A Síndrome da Boca Ardente (SBA é caracterizada por dor na cavidade oral, com ou sem sinais inflamatórios, mas sem lesões específicas. Acomete geralmente mulheres na faixa etária entre 40 a 60 anos. A dor é do tipo queimação, de intensidade moderada a severa, sendo a língua o local mais acometido, podendo haver sensação dolorosa também em gengivas, lábios e mucosa jugal. Pode haver piora da intensidade dolorosa no decorrer do dia, nos estados de tensão, fadiga, ao falar muito, à ingestão de alimentos picantes e/ou quentes e melhora com alimentos frios, trabalho e distração. O objetivo desta revisão é contemplar as possíveis etiologias da SBA, agrupando-as em 4 grandes grupos para que melhor possam ser estudados: dor oral de causa local, sistêmica, emocional e idiopática. Sabendo dos diagnósticos diferenciais da síndrome, estabelecemos um protocolo para o manejo destes pacientes. Dentre as etiologias de dor bucal local, deve-se pesquisar as de causa dentária, alérgicas e infecciosas. Para as causas sistêmicas, pesquisar doenças do tecido conectivo, doenças endócrinas, neurológicas, deficiências nutricionais e as alterações das glândulas salivares que levam à xerostomia. A etiologia da SBA pode ser de difícil diagnóstico, muitas vezes com mais de um fator causando dor na boca. A realização de anamnese detalhada, exame físico geral, inspeção minuciosa da cavidade oral e orofaringe, além de exames laboratoriais são de fundamental importância, para evitar que o tratamento dos pacientes com esta síndrome, seja baseado em tentativa e erro.The Burning Month Syndrome (BMS is an oral mucosa pain - with or without inflammatory signs - without any specific lesion. It is mostly observed in women aged 40-60 years. This pain feels like a moderate/severe burning, and it occurs more frequently on the tongue, but it may also be felt at the gingiva, lips and jugal mucosa. It may worsen during the day, during stress

  12. Cerebral activation during thermal stimulation of patients who have burning mouth disorder: an fMRI study. (United States)

    Albuquerque, Romulo J C; de Leeuw, Reny; Carlson, Charles R; Okeson, Jeffrey P; Miller, Craig S; Andersen, Anders H


    The pathophysiology of burning mouth disorder (BMD) is not clearly understood, but central neuropathic mechanisms are thought to be involved. The aim of this study was to gain insight into the pathophysiology associated with BMD by using functional magnetic resonance imaging (fMRI). Areas of brain activation following thermal stimulation of the trigeminal nerve of eight female patients with BMD (mean age 49.1+/-10.1) were mapped using fMRI and compared with those of eight matched pain-free volunteers (mean age 50.3+/-12.3). Qualitative and quantitative differences in brain activation patterns between the two study groups were demonstrated. BMD patients displayed greater fractional signal changes in the right anterior cingulate cortex (BA 32/24) and bilateral precuneus than did controls (p<0.005). The control group showed larger fractional signal changes in the bilateral thalamus, right middle frontal gyrus, right pre-central gyrus, left lingual gyrus, and cerebellum than did the BMD patients (p<0.005). In addition, BMD patients had less volumetric activation throughout the entire brain compared to the control group. Overall, BMD patients displayed brain activation patterns similar to those of patients with other neuropathic pain conditions and appear to process thermal painful stimulation to the trigeminal nerve qualitatively and quantitatively different than pain-free individuals. These findings suggest that brain hypoactivity may be an important feature in the pathophysiology of BMD.

    Spanemberg, Juliana Cassol; López, José López; de Figueiredo, Maria Antonia Zancanaro; Cherubini, Karen; Salum, Fernanda Gonçalves


    The aim of the present study was to assess the effect of low-level laser therapy (LLLT) in the treatment of burning mouth syndrome (BMS). A diode laser was used in 78 BMS patients who were randomly assigned into four groups: IR1W, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, LLLT weekly sessions, 10 sessions); IR3W, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, three LLLT weekly sessions, 9 sessions); red laser, n=19 (685 nm, 35 mW, 2 J, 72 J/cm2, 58 s, three LLLT weekly sessions, 9 sessions); and control-group (CG), n=19. Symptoms were assessed at the end of the treatment and eight weeks later; quality of life related to oral health was assessed using the Oral Health Impact Profile (OHIP-14). Statistical analysis was carried out using repeated measures analysis of variance followed by the posthoc Tukey test. There was significant reduction of the symptoms in all groups at the end of the treatment, which was maintained in the follow-up. The scores of the IR1W and IR3W laser groups differed significantly from those of the CG. There was also a decrease in the OHIP-14 scores in the four groups. The IR3W laser group scores differed significantly from those of the CG. LLLT reduces the symptoms of BMS and may be an alternative therapeutic strategy for the relief of symptoms in patients with BMS.

    Comparison between low-level laser therapy (LLLT) and clonazepam for treating burning mouth syndrome (BMS) patients has never been documented; the aim of this study was to assess the effects of LLLT photobiomodulation versus medical therapy with clonazepam on BMS. Thirty-three patients (25 female, 8 male, mean age = 67.12) were randomly allocated to two different groups: the first one (group A, 18 patients) underwent two laser irradiation sessions weekly for 5 weeks, whereas the second one (group B, 15 patients) received topical clonazepam therapy [half a tablet (2 mg) in the mouth without swallowing for 3 min, three times a day for 21 days]. LLLT was delivered with a continuous wave 980-nm aluminum gallium arsenide (AlGaAs) diode laser and the output of 300 mW, delivering a Fluence of 10 J/cm(2), using a "spot technique," with an average power density of about 1 W/cm(2). The laser probe was held perpendicularly at a distance of about 2 mm from the mucosa. Visual analogue scale (VAS), McGill Pain Questionnaire, present pain intensity (PPI), and Oral Health Impact Profile (OHIP-49) assessed sensation of pain. Hospital Anxiety and Depression Scale and Geriatric Depression Scale assessed levels of anxiety and depression. Twelve weeks after the end of treatment, patients treated with LLLT experienced a decrease in pain sensation reported for all the parameters analyzed: VAS (P = 0.004), McGill Pain Questionnaire (P = 0.002), PPI (P = 0.002), and OHIP-49 (P = 0.010). The group treated with clonazepam had less favorable results for VAS (P = 0.33), McGill Pain Questionnaire (P = 0.005), PPI (P = 0.013), and OHIP-49 (P = 0.25). Levels of anxiety and depression did not change statistically in any groups (P > 0.05). Comparing the two groups, LLLT appeared to be superior in improving pain perception, but statistically only at 8 weeks after the end of the protocol proposed (P = 0.026). Based on this preliminary trial, LLLT is capable

    Full Text Available Burn injuries are important in terms of causing serious disability and threatening life. With the establishment of modern burn treatment units and advances in acute care management contributed to a reduced mortality rate over the last decades. As a result of improved outcome, more attention has to be given to a comprehensive burn rehabilitation program. Burn rehabilitation is a process that starts from day of admission and continues for months or sometimes years after the initial event. The term ‘burn rehabilitation’ incorporates the physical, physiological and social aspects of care. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Burn rehabilitation aims to prevent the possible complications, minimalize joint contractures and deformities, increase range of motion, control hypertrophic scarring, achieve the best possible functional capacity and to regain the patients vocational and recreational activities.

    A 67-year-old woman suffered from a burning mouth feeling for 1.5 years and was referred by her dentist to a saliva clinic. At the clinic persistent xerostomia was diagnosed, and Sjögren's syndrome was suspected. After 1 year, a new measurement of the saliva secretion was carried out, which revealed a further decline in saliva secretion rate. The patient was consequently treated with an intra-oral electrostimulating device in order to stimulate the saliva secretion rate and reduce the feeling of a dry mouth. After 2 weeks, the patient experienced a considerable improvement of the subjective oral dryness.

    baja funcionalidad de las fibras nerviosas de pequeño calibre de la lengua en casi la mitad de los pacientes examinados. El examen histológico de la mucosa lingual evidenciaba una atrofia discreta en el 70% de los pacientes, mientras que la observación de las fibras nerviosas de pequeño calibre por medio de la inmunofluoresencia hacía suponer la presencia de alteraciones relacionadas con una polineuropatía de tipo periférico.Aims. Burning pain is considered characteristic of chronic neuropathic pain condition in general, and so me recent data seem to suggest peripheral or central nervous system involvement as possible underlying factor in BMS. This study was designed to determinate if burning mouth symptoms could be originated from a peripheal neuropathy of small diameter nerve fibres. Material and methods. The material of the study consisted of 25 patients (18 female, 7 male, 30-75 years; means 54 years. In all patients there were not: oral muco membranes lesions, oral muco membranes diseases, oral correlated diseases, oral dysfunctions, dental and periodontal diseases. Besides there were: no evidence of central nervous system pathology, no evidence of peripheral nervous system pathology, no presence of organic body disfunctions.

    Chadha, Priyanka; Hobday, Dorian; O'Connor, Edmund Fitzgerald; D'Cruz, David


    We present the case of a 69-year-old man who was found collapsed close to a heat source and admitted to hospital for severe sepsis. He was also found to have widespread blistering and ulceration of his right leg; however, a history was unobtainable due to reduced consciousness levels. The leg lesions had the initial appearance of mixed depth burns and a management plan was made to transfer the patient to a burns unit for debridement. It was subsequently noted that the patient had a previous diagnosis of seropositive erosive rheumatoid arthritis. A biopsy of the leg lesion was performed and a diagnosis of rheumatoid vasculitis confirmed. Treatment with systemic steroids, intravenous antibiotics and intravenous immunoglobulin therapy for severe hypogammaglobulinaemia was started, and the patient was not transferred for surgical debridement. Rheumatoid vasculitis is a rare and extremely serious complication of rheumatoid arthritis that can manifest in a number of ways, occasionally mimicking other conditions. This case is essential to raise awareness of rare, severe rheumatoid vasculitis and of the potential for its misdiagnosis as a mixed depth burn.

  4. Burn Injuries: Burn Depth, Physiopathology and Type of Burns

    Directory of Open Access Journals (Sweden)

    Kemalettin Koltka


    Full Text Available A significant burn injury is a serious and mortal event. The most important threat to life is hypovolemic shock with complex pathophysiologic mechanisms. Burn depth is classified as first, second, or third degree. Local inflammatory response results a vasodilatation and an increase in vascular permeability. A burn injury is a three dimensional ischemic wound. Zone of coagulation is the zone with maximum damage. Zone of stasis consists of damaged but viable tissues, the tissue is salvageable. In zone of hyperemia tissue perfusion is increased. At the beginning, cardiac output falls and systemic vascular resistance increases; cardiac performance improves as hypovolemia is corrected with fluid resuscitation. While cardiac output increases systemic vascular resistance falls below normal values and a hypermetabolic state develops. Pulmonary vascular resistance increases immediately after thermal injury and this is more prolonged. To avoid secondary pulmonary complications, the smallest resuscitation volume of fluids that maintains adequate tissue perfusion should be given. Changes parallel to the cardiovascular response develop in other organ systems. The reasons of burn injury can be thermal, electrical, chemical or radiation. It is important to know the exact mechanism of burn injury because of different therapies for a specific cause. In this review information about burn depth, local and systemic responses to burn injury and major causes of burn injury are presented.

  13. Partial Burn Laws in Propellant Erosive Burning

    Directory of Open Access Journals (Sweden)

    S.V. Finjakov


    Full Text Available Experimental and computer methods were developed for investigating the combustion phenomena in the propellants which burn in streams of hot gas flowing along the burn surfaces of the propellants. The experimental investigations allowed establishment of different dependencies for erosive burning. Computer solutions of the problem for double-base (DB propellants showed a good agreement with the experimental results. The suggested variant of modified theory considers the change of heat release in solids, the real burn surface roughness, the nonisothermality of boundary layer and the effect of gas mass blow from the propellant burn surface into the gas stream. This modified theory was used for studying burn laws at 30-1000 atm and up to gas stream sound velocities for different DB propellants. It was found that gas stream leads to splitting of the propellant burn laws, m = bp/sup v/. Pressure power (v, in this case depends on gas stream velocity (W, diameter of the propellant tube canal (d and gas stream temperature (T/sub w/. It is because of this that these burn laws were named partial burn laws. They have the form (m = bp/sup w(omega/ w,d,T/sub w/ -const. The dependencies w(omega = f(w,d,T/sub w/ were obtained by the modified theory. It was found that omega values mainly decrease when pressure increases beginning from ~200 to 400 atm and they can decrease up to w(omega = 0,1- 0,3. Similar results can be obtained for composite propellants.

  14. [The pain from burns]. (United States)

    Latarjet, J


    The painful events associated with the treatment of a severe burn can, because of their long-lasting and repetitive characteristics, be one of the most excruciating experiences in clinical practice. Moreover, burn pain has been shown to be detrimental to burn patients. Although nociception and peripheral hyperalgesia are considered the major causes of burn pain, the study of more hypothetical mechanisms like central hyperalgesia and neuropathic pain may lead to a better understanding of burn pain symptoms and to new therapeutic approaches. Continuous pain and intermittent pain due to therapeutic procedures are two distinct components of burn pain. They have to be evaluated and managed separately. Although continuous pain is by far less severe than intermittent pain, the treatment is, in both cases, essentially pharmacological relying basically on opioids. Because of wide intra- and inter-individual variations, protocols will have to leave large possibilities of adaptation for each case, systematic pain evaluation being mandatory to achieve the best risk/benefit ratio. Surprisingly, the dose of medication decreases only slowly with time, a burn often remaining painful for long periods after healing. Non pharmacological treatments are often useful and sometimes indispensable adjuncts; but their rationale and their feasibility depends entirely on previous optimal pharmacological control of burn pain. Several recent studies show that burn pain management is inadequate in most burn centres.

  2. Critical issues in burn care. (United States)

    Holmes, James H


    Burn care, especially for serious burn injuries, represents a considerable challenge for the healthcare system. The American Burn Association has established a number of strategies for the management of burn patients and dedicates its efforts and resources to promoting and supporting burn-related research, education, care, rehabilitation, and prevention, often in collaboration with other organizations. The American Burn Association has recommended that patients with serious burns be referred to a designated burn center, ie, a hospital outfitted with specialized personnel and equipment dedicated to burn care. Burn centers have been operational for over 50 years, but the complexity and costs of providing specialized burn care have given rise to a number of critical administrative and political issues. These include logistical limitations imposed by the uneven national distribution of burn centers and a potential shortage of burn beds, both during everyday conditions and in the event of a mass disaster. Burn surgeon shortages have also been identified, stemming, in part, from a lack of specialized burn care training opportunities. There is currently a lack of quality outcome data to support evidence-based recommendations for burn care, and burn care centers are compromised by problems obtaining reimbursement for the care of uninsured and publicly insured out-of-state burn patients. Initiatives are underway to maintain efficient burn care facilities that are fully funded, easily accessible, and most importantly, provide optimal, evidence-based care on a daily basis, and are well-equipped to handle a surge of patients during a disaster situation.

  3. Pain in burn patients. (United States)

    Latarjet, J; Choinère, M


    While severe pain is a constant component of the burn injury, inadequate pain management has been shown to be detrimental to burn patients. Pain-generating mechanisms in burns include nociception, primary and secondary hyperalgesia and neuropathy. The clinical studies of burn pain characteristics reveal very clear-cut differences between continuous pain and pain due to therapeutic procedures which have to be treated separately. Some of the main features of burn pain are: (1) its long-lasting course, often exceeding healing time, (2) the repetition of highly nociceptive procedures which can lead to severe psychological disturbances if pain control is inappropriate. Pharmaco-therapy with opioids is the mainstay for analgesia in burned patients, but non-pharmacological techniques may be useful adjuncts. Routine pain evaluation is mandatory for efficient and safe analgesia. Special attention must be given to pain in burned children which remains too often underestimated and undertreated. More educational efforts from physicians and nursing staff are necessary to improve pain management in burned patients.

  5. Hand chemical burns. (United States)

    Robinson, Elliot P; Chhabra, A Bobby


    There is a vast and ever-expanding variety of potentially harmful chemicals in the military, industrial, and domestic landscape. Chemical burns make up a small proportion of all skin burns, yet they can cause substantial morbidity and mortality. Additionally, the hand and upper extremity are the most frequently involved parts of the body in chemical burns, and therefore these injuries may lead to severe temporary or permanent loss of function. Despite this fact, discussion of the care of these injuries is sparse in the hand surgery literature. Although most chemical burns require only first response and wound care, some require the attention of a specialist for surgical debridement and, occasionally, skin coverage and reconstruction. Exposure to certain chemicals carries the risk of substantial systemic toxicity and even mortality. Understanding the difference between thermal and chemical burns, as well as special considerations for specific compounds, will improve patient treatment outcomes.

  6. [Chickenpox, burns and grafts]. (United States)

    Rojas Zegers, J; Fidel Avendaño, L


    An outbreak of chickenpox that occurred at the Burns Repair Surgery Unit, Department of Children's Surgery, Hospital R. del Río, between June and November, 1975, is reported. 27 cases of burned children were studied, including analysis of correlations of the stages and outcome of the disease (varicela), the trauma (burns) and the graft (repair surgery). As a result, the authors emphasize the following findings: 1. Burns and their repair are not aggravating factors for varicella. In a small number of cases the exanthema looked more confluent in the graft surgical areas and in the first degree burns healing spontaneously. 2. Usually there was an uneventful outcome of graft repair surgery on a varicella patient, either during the incubation period, the acme or the convalescence. 3. The fact that the outmost intensity of secondary viremia of varicella occurs before the onset of exanthemia, that is, during the late incubation period, is confirmed.

    Schiestl, Clemens; Meuli, Martin; Trop, Marija; Neuhaus, Kathrin


    Small and moderate scalds in toddlers are still the most frequent thermal injuries the pediatric surgeons have to face today. Over the last years, surgical treatment of these patients has changed in many aspects. Due to new dressing materials and new surgical treatment strategies that are particularly suitable for children, today, far better functional and aesthetic long-term results are possible. While small and moderate thermal injuries can be treated in most European pediatric surgical departments, the severely burned child must be transferred to a specialized, ideally pediatric, burn center, where a well-trained multidisciplinary team under the leadership of a (ideally pediatric) burn surgeon cares for these highly demanding patients. In future, tissue engineered full thickness skin analogues will most likely play an important role, in pediatric burn as well as postburn reconstructive surgery.

    Curran, Kevin; Coyle, Damian


    The recommendation to change breathing patterns from the mouth to the nose can have a significantly positive impact upon the general well being of the individual. We classify nasal and mouth breathing by using an acoustic sensor and intelligent signal processing techniques. The overall purpose is to investigate the possibility of identifying the differences in patterns between nasal and mouth breathing in order to integrate this information into a decision support system which will form the basis of a patient monitoring and motivational feedback system to recommend the change from mouth to nasal breathing. Our findings show that the breath pattern can be discriminated in certain places of the body both by visual spectrum analysis and with a Back Propagation neural network classifier. The sound file recoded from the sensor placed on the hollow in the neck shows the most promising accuracy which is as high as 90%.

    Mohamed Rizon


    Full Text Available Problem statement: This study presented algorithms to detect mouth from color and intensity images. Approach: First, this algorithm detected the face region in the image and extracts intensity valleys from the face region. Next, the algorithm extracted iris candidates from the valleys and computed the costs for each pair of iris candidates. Finally, a pair of iris candidates was selected as irises by using the computed costs. Projection based method had been used to detect mouth corresponding to irises location. Results: By experiment, the proposed algorithm detected 90% of full mouth region for South East Asian database and 74% for European database. Conclusion: The algorithm was considered successful to detect mouth detection under variation of pose, illumination and orientation. For future improvement, more preprocessing steps might be needed to enhance and eliminate the effect of beard, moustache and illumination.

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    Hsu, H-Y; Yamaguchi, K


    This study examined the effect of mouth breathing on the strength and duration of vertical effect on the posterior teeth using related functional parameters during 3 min of gum chewing in 39 nasal breathers. A CO(2) sensor was placed over the mouth to detect expiratory airflow. When no airflow was detected from the mouth throughout the recording period, the subject was considered a nasal breather and enrolled in the study. Electromyographic (EMG) activity was recorded during 3 min of gum chewing. The protocol was repeated with the nostrils occluded. The strength of the vertical effect was obtained as integrated masseter muscle EMG activity, and the duration of vertical effect was also obtained as chewing stroke count, chewing cycle variation and EMG activity duration above baseline. Baseline activity was obtained from the isotonic EMG activity during jaw movement at 1.6 Hz without making tooth contact. The duration represented the percentage of the active period above baseline relative to the 3-min chewing period. Paired t-test and repeated analysis of variance were used to compare variables between nasal and mouth breathing. The integrated EMG activity and the duration of EMG activity above baseline, chewing stroke count and chewing cycle significantly decreased during mouth breathing compared with nasal breathing (Pmouth breathing was significantly greater than nasal breathing (PMouth breathing reduces the vertical effect on the posterior teeth, which can affect the vertical position of posterior teeth negatively, leading to malocclusion.

  1. An assessment of burn care professionals' attitudes to major burn.

    LENUS (Irish Health Repository)

    Murphy, A D


    The resuscitation of severe burn remains a controversial area within the burn care profession. There is ongoing debate as to what percentage burn is associated with a sufficient quality of life to support initial resuscitation efforts. We conducted a survey of delegates at the 39th Annual Meeting of the British Burns Association (2005), regarding attitudes towards resuscitation following major burns. Respondents were asked the maximum percentage total body surface area (TBSA) burn beyond which they would not wish to be resuscitated. They were also asked what maximum TBSA they perceived to be commensurate with an acceptable quality of life (QOL). One hundred and forty three of 300 delegates responded to the questionnaire. Thirty three percent of respondents would not wish to be resuscitated with 50-75% TBSA burns or greater. A further 35% would not wish to have life-sustaining intervention with 75-95% TBSA burns or greater. The remaining 32% indicated that they would not want resuscitation with TBSA burns>95%. Regardless of TBSA affected, 16% would not wish resuscitation if they had full thickness facial burns, a further 10% did not want resuscitation if both their hands and faces were affected. Our survey demonstrates the diversity of personal preference amongst burn care professionals. This would suggest that a unifying philosophy regarding the resuscitation of extensive burns will remain elusive.

Each selected article is mentioned briefly with editorial comment.

  8. Dry mouth: aging and oral health. (United States)

    Navazesh, Mahvash


    Dry mouth is a common complaint among older adults, and the aging process is erroneously considered by many to be the primary cause. The subjective complaint of dry mouth (xerostomia) is not always associated with objective evidence of a reduced saliva flow rate (salivary gland hypofunction). Moreover, there are patients who have reduced saliva flow rates and are asymptomatic. Xerostomia and salivary gland hypofunction are associated with sundry oral and systemic complications and affect the quality of an individual's life. This article includes the common causes of xerostomia and salivary gland hypofunction and addresses the common complications of and routine therapeutic modalities available for these conditions in the elderly.

  12. [Electrical burns in children. 3 years of case histories]. (United States)

    Caneira, E; Serafim, Z; Duarte, R; Leal, M J


    The Burn Unit of Dona Estefânia Hospital admitted a total of 454 patients from January 1992 to January 1995, 24 of these patients suffered from electric shock. Of these 24 patients 3 suffered burns in the mouth, 15 in one or both hands and 6 multiple burns. In 19 patients the burns were up to 1%. A description is made of 5 cases, male children between the ages of 9 and 13 years, which were deemed severe. The incidents occurred outdoors with different voltages and in activities considered of ludic or experimental nature: two on the roof of a house, two with railway cables and one with an electrical cable in a port zone. The burnt areas vary between 4% and 70%, all of them 2nd and 3rd degree, with hospitalization lasting from 36 to 116 days. In addition to early and coordinated medical and rehabilitative treatment, according to individual needs, a description is also made of the cutaneous sequelae (deforming cicatrices, bridles), neurologic and psychologic sequelae, with emphasis on a patient who underwent amputation of the lower left leg and 4th and 5th ranges of the right foot. It was concluded that measures should be taken in education and legislation to prevent these accidents. Relevance is given to the need for a multidisciplinary team and specialized center for the treatment of these patients.

  13. Burn epidemiology and cost of medication in paediatric burn patients. (United States)

    Koç, Zeliha; Sağlam, Zeynep


    Burns are common injuries that cause problems to societies throughout the world. In order to reduce the cost of burn treatment in children, it is extremely important to determine the burn epidemiology and the cost of medicines used in burn treatment. The present study used a retrospective design, with data collected from medical records of 140 paediatric patients admitted to a burn centre between 1 January 2009 and 31 December 2009. Medical records were examined to determine burn epidemiology, medication administered, dosage, and duration of use. Descriptive statistical analysis was completed for all variables; chi-square was used to examine the relationship between certain variables. It was found that 62.7% of paediatric burns occur in the kitchen, with 70.7% involving boiling water; 55.7% of cases resulted in third-degree burns, 19.3% required grafting, and mean duration of hospital stay was 27.5 ± 1.2 days. Medication costs varied between $1.38 US dollars (USD) and $14,159.09, total drug cost was $46,148.03 and average cost per patient was $329.63. In this study, the medication cost for burn patients was found to be relatively high, with antibiotics comprising the vast majority of medication expenditure. Most paediatric burns are preventable, so it is vital to educate families about potential household hazards that can be addressed to reduce the risk of a burn. Programmes are also recommended to reduce costs and the inappropriate prescribing of medication.

  17. [Hydrofluoric acid burns]. (United States)

    Holla, Robin; Gorter, Ramon R; Tenhagen, Mark; Vloemans, A F P M Jos; Breederveld, Roelf S


    Hydrofluoric acid is increasingly used as a rust remover and detergent. Dermal contact with hydrofluoric acid results in a chemical burn characterized by severe pain and deep tissue necrosis. It may cause electrolyte imbalances with lethal consequences. It is important to identify high-risk patients. 'High risk' is defined as a total affected body area > 3% or exposure to hydrofluoric acid in a concentration > 50%. We present the cases of three male patients (26, 31, and 39 years old) with hydrofluoric acid burns of varying severity and describe the subsequent treatments. The application of calcium gluconate 2.5% gel to the skin is the cornerstone of the treatment, reducing pain as well as improving wound healing. Nails should be thoroughly inspected and possibly removed if the nail is involved, to ensure proper healing. In high-risk patients, plasma calcium levels should be evaluated and cardiac monitoring is indicated.

  18. Alongshore sediment bypassing as a control on river mouth morphodynamics (United States)

    Nienhuis, Jaap H.; Ashton, Andrew D.; Nardin, William; Fagherazzi, Sergio; Giosan, Liviu


    River mouths, shoreline locations where fluvial and coastal sediments are partitioned via erosion, trapping, and redistribution, are responsible for the ultimate sedimentary architecture of deltas and, because of their dynamic nature, also pose great management and engineering challenges. To investigate the interaction between fluvial and littoral processes at wave-dominated river mouths, we modeled their morphologic evolution using the coupled hydrodynamic and morphodynamic model Delft3D-SWAN. Model experiments replicate alongshore migration of river mouths, river mouth spit development, and eventual spit breaching, suggesting that these are emergent phenomena that can develop even under constant fluvial and wave conditions. Furthermore, we find that sediment bypassing of a river mouth develops though feedbacks between waves and river mouth morphology, resulting in either continuous bypassing pathways or episodic bar bypassing pathways. Model results demonstrate that waves refracting into the river mouth bar create a zone of low alongshore sediment transport updrift of the river mouth, which reduces sediment bypassing. Sediment bypassing, in turn, controls the river mouth migration rate and the size of the river mouth spit. As a result, an intermediate amount of river discharge maximizes river mouth migration. The fraction of alongshore sediment bypassing can be predicted from the balance between the jet and the wave momentum flux. Quantitative comparisons show a match between our modeled predictions of river mouth bypassing and migration rates observed in natural settings.

  19. The hair color-highlighting burn: a unique burn injury. (United States)

    Peters, W


    A unique, preventable, 2.8 x 3.7-cm, full-thickness scalp burn resulted after a woman underwent a professional color-highlighting procedure at a hair salon. The burn appeared to result from scalp contact with aluminum foil that had been overheated by a hair dryer during the procedure. The wound required debridement and skin grafting and 3 subsequent serial excisions to eliminate the resulting area of burn scar alopecia. The preventive aspects of this injury are discussed.

  20. [The organization of burn care]. (United States)

    Latarjet, Jacques


    In 2002, the organisation of burn care is confronted to a great deficiency in burn epidemiological datas. The main mechanisms of hospitalized burns are somehow wellknown in industrialized countries: about 60% scalds and 30% flame burns; as well as the place of occurrence (60% at home, and 20% at work), and the risk groups (3 times more important for the age group 0-4 years old). The incidence of burns needing medical care (all levels) (250/100,000 inh/yr) or hospitalization (15-20/100,000 inh/yr) is much more uncertain. The statistics of Diagnosis Related Groups (DRG), for hospitalized patients will allow in France very shortly to know more about the most rational ways of dispatching and treating them. They already show that only 30% of hospitalized burned patients are treated in specialized facilities.

  1. Social media: the word of mouth revolution. (United States)

    Garven, Joseph J


    Many dental practices today find themselves uncertain about the new social media universe, and in particular with how to relate to younger patients. The power of social networking is its immediate access to the word of mouth exchange of information, and the word of mouth avenue itself is recognized as the single most effective form of advertising. To tap into that phenomenon, begin by investing a small amount of time and effort to understand the basics of social networking. Sign up for Facebook and Twitter. First-hand experience interacting in a social network is the vital first step. The bottom line is simply this: To begin to understand this new arena of communication, you first have to join the conversation.

  3. [Oral medicine 2. Treatment of dry mouth]. (United States)

    Vissink, A; Visser, A; Spijkervet, F K L


    Treatment of dry mouth starts with determining the salivary gland function by measuring the unstimulated and stimulated flow rate.Treatment depends on these measurements. Iffunctioning salivary gland tissues with saliva producing potential are present, stimulation of the salivary glands by gum chewing or sucking sugar-free sweets is recommended. Salivary gland stimulation may also be achieved using medications, acupuncture and electrostimulation. If stimulation is insufficient, moistening the oral mucosa with a sip ofwater regularly during the day is one of the easiest and most effective methods of easing dry mouth. In addition, the use of saliva replacement therapy might be beneficial, but only with proper instruction. With regard to the caries risk in dentate patients, a fluoride rinse or gel should be prescribed.

  4. Genital burns and vaginal delivery. (United States)

    Pant, R; Manandhar, V; Wittgenstein, F; Fortney, J A; Fukushima, C


    Obstetric complications may result from burn scarring in the genital area. Women in developing countries typically squat around cooking fires, and burns are common. This recent case in Nepal describes obstructed labor in a young woman whose genital area had extensive scarring from a cooking fire injury. Proper antenatal assessment by health care providers can reduce the risk to mothers and infants of the consequences of a birth canal damaged or obstructed by burn scarring.

  5. [Epidemiology of burns in France]. (United States)

    Latarjet, Jacques; Ravat, François


    As with most traumas, the epidemiology of the "burn" health-event has long been neglected by public health doctors and rarely considered by burns specialists. There were therefore few verified data and many approximations and preconceived ideas. The gathering of information recently undertaken in France enables the reliability of the data to be improved and the diagnostic and demographic elements relating to hospitalised patients with burns to be established.

  6. Marginally Stable Nuclear Burning (United States)

    Strohmayer, Tod E.; Altamirano, D.


    Thermonuclear X-ray bursts result from unstable nuclear burning of the material accreted on neutron stars in some low mass X-ray binaries (LMXBs). Theory predicts that close to the boundary of stability oscillatory burning can occur. This marginally stable regime has so far been identified in only a small number of sources. We present Rossi X-ray Timing Explorer (RXTE) observations of the bursting, high-inclination LMXB 4U 1323-619 that reveal for the first time in this source the signature of marginally stable burning. The source was observed during two successive RXTE orbits for approximately 5 ksec beginning at 10:14:01 UTC on March 28, 2011. Significant mHz quasi-periodic oscillations (QPO) at a frequency of 8.1 mHz are detected for approximately 1600 s from the beginning of the observation until the occurrence of a thermonuclear X-ray burst at 10:42:22 UTC. The mHz oscillations are not detected following the X-ray burst. The average fractional rms amplitude of the mHz QPOs is 6.4% (3 - 20 keV), and the amplitude increases to about 8% below 10 keV.This phenomenology is strikingly similar to that seen in the LMXB 4U 1636-53. Indeed, the frequency of the mHz QPOs in 4U 1323-619 prior to the X-ray burst is very similar to the transition frequency between mHz QPO and bursts found in 4U 1636-53 by Altamirano et al. (2008). These results strongly suggest that the observed QPOs in 4U 1323-619 are, like those in 4U 1636-53, due to marginally stable nuclear burning. We also explore the dependence of the energy spectrum on the oscillation phase, and we place the present observations within the context of the spectral evolution of the accretion-powered flux from the source.

  7. Exercise following burn injury. (United States)

    de Lateur, Barbara J; Shore, Wendy S


    Fatigue is a major barrier to recovery for burned individuals. Studies indicate that a slow return to normal or near-normal muscle strength is the natural course of recovery. With no special interventions, other than the "usual care" tailored to the needs of the individual, postburn patients will make gradual improvement in strength and aerobic capacity. Using the principle of initial condition (the worse the initial condition, the greater the response to exercise intervention) the authors outline an augmented exercise program that should result in a robust improvement in aerobic capacity.

    Full Text Available An orally disintegrating tablet or mouth dissolving tablet (MDT is a drug dosage form available for a limited amount of over-the-counter (OTC and prescription medications. MDTs differ from traditional tablets in that they are designed to be dissolved on the tongue rather than swallowed whole. A variety of pharmaceutical research has been conducted to develop new dosage forms. Among the dosage forms developed to facilitate ease of medication, the mouth dissolving tablet (MDT is one of the most widely employed commercial products. As our society is becoming increasingly aged, the development of mouth dissolving tablets have been formulated for pediatric, geriatric, and bedridden patients and for active patients who are busy and travelling and may not have access to water. Such formulations provide an opportunity for product line extension in the many elderly persons will have difficulties in taking conventional oral dosage forms (viz., solutions, suspensions, tablets, and capsules because of hand tremors and dysphagia. Oral delivery is currently the gold standard in the pharmaceutical industry where it is regarded as the safest, most convenient and most economical method of drug delivery having the highest patient compliance. Recent development in fast disintegrating technology mainly works to improve the disintegration quality of these delicate dosage forms without affecting their integrity. This article focuses on the patented technologies available and the advances made so far in the field of fabrication of mouth dissolving tablets.

    Full Text Available Severe burn trauma causes serious metabolic derangements. Increased metabolic rate which is apart of a pathophysiologic characteristic of burn trauma results in protein-energy malnutrition. This situation causes impaired wound healing, muscle and fat tissue’s breakdown, growth retardation in children and infections. Nutrition support is vital in the treatment strategies of burn victims to prevent high mortal and disabling complications in this devastating trauma. Our aim in this study is to review management of nutrition in burn victims. (Journal of the Turkish Society Intensive Care 2012; 10: 74-83

  11. How to manage burns in primary care.


    Waitzman, A. A.; Neligan, P. C.


    Burns are common injuries; more than 200,000 occur in Canada annually. Nearly all burn injuries can be managed on on outpatient basis. Appropriate treatment depends on burn depth, extent, and location. Special types of burns, such as chemical, tar, and electrical injuries, need specific management strategies. Prevention through education is important to reduce the incidence of burns.

  13. Accidental Cutaneous Burns Secondary to Salbutamol Metered Dose Inhaler

    Directory of Open Access Journals (Sweden)

    Ashutosh Kale


    Full Text Available We report a case of accidental cutaneous burns caused by salbutamol metered dose inhaler. A 9-year-old boy underwent dental extraction at a children's hospital and was incidentally noted to have burn injuries on dorsum of both hands. On questioning, the boy revealed that a few days ago his 14-year-old brother, who is an asthmatic, playfully sprayed his salbutamol metered dose inhaler on the back of both his hands with the inhaler's mouth piece being in direct contact with the patient's skin. On examination, there was a rectangular area of erythema with superficial peeling on the dorsum of both hands, the dimensions of which exactly matched those of the inhaler's mouthpiece. It is possible that the injury could have been a chemical burn from the pharmaceutical/preservative/propellant aerosol or due to the physical effect of severe cooling of the skin or mechanical abrasive effect of the aerosol blasts or a combination of some or all the above mechanisms. This case highlights the importance of informing children and parents of the potentially hazardous consequences of misusing a metered dose inhaler.

  14. Bad advice; bad burn: a new problem in burn prevention. (United States)

    Deans, L; Slater, H; Goldfarb, I W


    Deep partial-thickness burns had been inflicted on the perineal area of an infant who was recently treated in our Burn Center. The burns were a result of advice to the patient's mother by a pediatrician. The doctor told her to use a hair dryer to prevent diaper rash. We surveyed pediatricians, well-baby clinics, and pediatric nurse practitioners in our area and found that approximately half of them advised the use of hair dryers to treat or prevent diaper rash. We tested four widely available hand-held hair dryers to determine potential for inflicting burn injury. All of the dryers are capable of delivering air heated to at least 53 degrees C after 2 minutes of use. We believe that warnings against the use of hair dryers for perineal hygiene should be included in burn prevention programs.

    Approximately 3415 research articles were published with burns in the title, abstract, and/or keyword in 2013. We have continued to see an increase in this number; the following reviews articles selected from these by the Editor of one of the major journals (Burns) and colleagues that in their opinion are most likely to have effects on burn care treatment and understanding. As we have done before, articles were found and divided into the following topic areas: epidemiology of injury and burn prevention, wound and scar characterization, acute care and critical care, inhalation injury, infection, psychological considerations, pain and itching management, rehabilitation and long-term outcomes, and burn reconstruction. The articles are mentioned briefly with notes from the authors; readers are referred to the full papers for details.

  19. The biology of burn injury. (United States)

    Evers, Lars H; Bhavsar, Dhaval; Mailänder, Peter


    Burn injury is a complex traumatic event with various local and systemic effects, affecting several organ systems beyond the skin. The pathophysiology of the burn patient shows the full spectrum of the complexity of inflammatory response reactions. In the acute phase, inflammation mechanism may have negative effects because of capillary leak, the propagation of inhalation injury and the development of multiple organ failure. Attempts to mediate these processes remain a central subject of burn care research. Conversely, inflammation is a necessary prologue and component in the later-stage processes of wound healing. In this review, we are attempting to present the current science of burn wound pathophysiology and wound healing. We also describe the evolution of innovative strategies for burn management.

    The recommendation to change breathing patterns from the mouth to the nose can have a significantly positive impact upon the general well being of the individual. We classify nasal and mouth breathing by using an acoustic sensor and intelligent signal processing techniques. The overall purpose is to investigate the possibility of identifying the differences in patterns between nasal and mouth breathing in order to integrate this information into a decision support system which will form the basis of a patient monitoring and motivational feedback system to recommend the change from mouth to nasal breathing.

    Full Text Available Introduction Understanding of fluid shifts and recognition of the importance of early and appropriate fluid replacement therapy have significantly reduced mortality in the early post burn period. After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

  2. Sedation and Analgesia in Burn

    Özkan Akıncı


    Full Text Available Burn injury is one of the most serious injuries that mankind may face. In addition to serious inflammation, excessive fluid loss, presence of hemodynamic instability due to intercurrent factors such as debridements, infections and organ failure, very different levels and intensities of pain, psychological problems such as traumatic stress disorder, depression, delirium at different levels that occur in patient with severe burn are the factors which make it difficult to provide the patient comfort. In addition to a mild to moderate level of baseline permanent pain in burn patients, which is due to tissue damage, there is procedural pain as well, which occurs by treatments such as grafting and dressings, that are severe, short-term burst style 'breakthrough' pain. Movement and tactile stimuli are also seen in burn injury as an effect to sensitize the peripheral and central nervous system. Even though many burn centers have established protocols to struggle with the pain, studies show that pain relief still inadequate in burn patients. Therefore, the treatment of burn pain and the prevention of possible emergence of future psychiatric problems suc as post-traumatic stress disorder, the sedative and anxiolytic agents should be used as a recommendation according to the needs and hemodynamic status of individual patient.

    Full Text Available Rehabilitation is an essential and integral part of burn treatment. It is not something which takes place following healing of skin grafts or discharge from hospital; instead it is a process that starts from day one of admission and continues for months and sometimes years after the initial event. Burns rehabilitation is not something which is completed by one or two individuals but should be a team approach, incorporating the patient and when appropriate, their family. The term ′Burns Rehabilitation′ incorporates the physical, psychological and social aspects of care and it is common for burn patients to experience difficulties in one or all of these areas following a burn injury. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. The aims of burn rehabilitation are to minimise the adverse effects caused by the injury in terms of maintaining range of movement, minimising contracture development and impact of scarring, maximising functional ability, maximising psychological wellbeing, maximising social integration

    Foyatier, J L; Comparin, J P; Boulos, J P; Bichet, J C; Jacquin, F


    The deep burns of the face can lead to horrible scars functionally and aesthetically. Treatment of these scars need several surgical interventions frequently and during many years. In our region we deal with this type of wounds as team work, multidisciplinary approach carrying out many process starting by emergency treatment of acute burns till the social rehabilitation. The expansion technique was great help in improving the shape of scars, by using the expanding skin as full thickness grafts. Reconstruction of the anatomical units and application of aesthetic techniques (like rhinoplasty, lifting, tattooing and autologous fat injections) participate equally in improving the quality of results. Many examples of treatments of burns scars are shown.

    Cresol, which is used as a disinfectant and insecticide, has erosive effects on epidermal and epithelial tissues in the body. Oral exposure causes gastrointestinal corrosive injuries as a direct chemical burn. We report herein a case of suicidal poisoning by ingestion of cresol solution. An octogenarian man with depression was found dead approximately 14 h after exposure to less than 500 mL of saponated cresol solution. Macroscopically, corrosive lesions such as red-to-brown-colored epithelium and edematous thickening of walls were seen in the skin, mouth, oral cavity, esophagus, and stomach. Histopathologically, coagulative necrosis and vascular dilatation were detected from mucosal to muscular layers in the esophagus, stomach, and duodenum. Congestive edema of the lungs, edematous changes in the brain, and proximal tubular necrosis of the kidneys were seen, suggesting acute circulatory disturbance due to shock. This human case offers valuable information on the direct irritation and shock induced by systemic exposure to corrosive substances.

  7. Regimes Of Helium Burning

    CERN Document Server

    Timmes, F X


    The burning regimes encountered by laminar deflagrations and ZND detonations propagating through helium-rich compositions in the presence of buoyancy-driven turbulence are analyzed. Particular attention is given to models of X-ray bursts which start with a thermonuclear runaway on the surface of a neutron star, and the thin shell helium instability of intermediate-mass stars. In the X-ray burst case, turbulent deflagrations propagating in the lateral or radial directions encounter a transition from the distributed regime to the flamlet regime at a density of 10^8 g cm^{-3}. In the radial direction, the purely laminar deflagration width is larger than the pressure scale height for densities smaller than 10^6 g cm^{-3}. Self-sustained laminar deflagrations travelling in the radial direction cannot exist below this density. Similarily, the planar ZND detonation width becomes larger than the pressure scale height at 10^7 g cm^{-3}, suggesting that a steady-state, self-sustained detonations cannot come into exista...

  8. Hair dryer burns in children. (United States)

    Prescott, P R


    Three children with burn injuries caused by home hair dryers are described. In one patient the injury was believed to be accidental, and in the other two cases the injuries were deliberately caused by a caretaker. The lack of prior experience with hair dryer burns initially led to suspicion of other causes. The characteristics of each case aided in the final determination of accidental vs nonaccidental injury. These cases prompted testing of home hair dryers to determine their heat output. At the highest heat settings, the dryers rapidly generated temperatures in excess of 110 degrees C. After the dryers were turned off, the protective grills maintained sufficient temperatures to cause full-thickness burns for up to 2 minutes. These cases and the results of testing demonstrate that hair dryers must be added to the list of known causes of accidental and nonaccidental burns in children.

    Karimi, Hamid; Nourizad, Samad; Momeni, Mahnoush; Rahbar, Hosein; Momeni, Mazdak; Farhadi, Khosro


    An 18-year-old woman was admitted to Motahari Burn Center suffering from 30% burns. Treatment modalities were carried out for the patient and she was discharged after 20 days. Three to four months later she developed hypertrophic scar on her chest and upper limbs. At the same time she developed galactorrhea in both breasts and had a disturbed menstrual cycle four months post-burn. On investigation, we found hyperprolactinemia and no other reasons for the high level of prolactin were detected.She received treatment for both the hypertrophic scar and the severe itching she was experiencing. After seven months, her prolactin level had decreased but had not returned to the normal level. It seems that refractory hypertrophic scar is related to the high level of prolactin in burns patients.

  16. The use of acoustic stimulation to inspect the fetal mouth

    Lee, Keun Young; Jun, Hyun Ah; Jang, Pong Rheem; Lee, Keung Hee [Hallym University College of Medicine, Seoul (Korea, Republic of); Nagey, David A. [The Johns Hopkins University, Baltimore (United States)


    The normal neonatal response to sound stimulus consists of a generalized paroxysmal startle reflex. We recently noted an increase in fetal movements, head turning, mouth opening, tongue protrusion, cheek motion, hand to head movement and fetal eye blinking subsequent to fetal vibroacoustic stimulation. These movements are thought to represent portions of a startle response. Evaluation of the fetal face is an essential part of routine sonographic examination and of a level II examination. The complexity of the face in combination with suboptimal positioning may make it difficult to obtain adequate images of the fetal mouth. The fetal mouth is especially difficult to examine if it remains closed. It appeared to us that approximately 50% of the time, fetuses may be seen touching their face and head with their hands. This action may make evaluation of the face more difficult because of the shadowing caused by the overlying bones of the hands. We hypothesized that if vibroacoustic stimulation brings about fetal mouth movement and opening and/or withdrawal of the fetal hand from the mouth, it may facilitate anatomic evaluation for cleft lip and palate. Sonographic examination of the fetal mouth is facilitated if the mouth is open or moving. This study was designed to determine whether acoustic stimulation of the fetus would cause it to move its mouth. 109 women with uncomplicated pregnancies between 20 and 39 weeks gestation consented.

  17. Erosive burning of solid propellants (United States)

    King, Merrill K.


    Presented here is a review of the experimental and modeling work concerning erosive burning of solid propellants (augmentation of burning rate by flow of product gases across a burning surface). A brief introduction describes the motor design problems caused by this phenomenon, particularly for low port/throat area ratio motors and nozzleless motors. Various experimental techniques for measuring crossflow sensitivity of solid propellant burning rates are described, with the conclusion that accurate simulation of the flow, including upstream flow development, in actual motors is important since the degree of erosive burning depends not only on local mean crossflow velocity and propellant nature, but also upon this upstream development. In the modeling area, a brief review of simplified models and correlating equations is presented, followed by a description of more complex numerical analysis models. Both composite and double-base propellant models are reviewed. A second generation composite model is shown to give good agreement with data obtained in a series of tests in which composite propellant composition and heterogeneity (particle size distribution) were systematically varied. Finally, the use of numerical models for the development of erosive burning correlations is described, and a brief discussion of scaling is presented.

    Full Text Available One of the most challenging cases in forensic medicine is ascertaining the cause of death of burnt bodies under suspicious circumstances. The key questions that arise at the time of investigation include: 1  Was the person alive or dead prior to fire accident?  Did the victim die because of burn?  If death was not related to burns, could burns play a role in causing death?  Were the burns sustained accidentally, did the person commit suicide or was the person murdered?  Are the circumstances suggesting an attempt to conceal crime?  How was the fire started?  How was the victim identified?  In case of mass fatalities, who died first? Postmortem burning of corpses is supposed to be one of the ways to hide a crime. Differentiating the actual cause of death in burn patients is therefore important. Medical examiners usually focus on the defining the changes that occur in tissues while forensic anthropologists deal with the changes related to the bone with or without any the influence of other tissues. Under the circumstances of fire, differentiating the perimortem trauma from that of postmortem cause of bone fractures is vital in determining the cause and motive of death

  19. Burn treatment in the elderly. (United States)

    Keck, M; Lumenta, D B; Andel, H; Kamolz, L P; Frey, M


    The population of elderly patients is expected to rise continuously over the next decades due to global demographic changes. The elderly seem to be most vulnerable to burns and their management remains undoubtedly a challenge. A clear age margin for elderly patients is not yet defined, but most studies adhere to the inclusion of patients 65 years and above, but the general condition and social situation must be taken into account. The understanding of the physiological basis of aging and its related pathophysiological changes has only marginally influenced treatment and decision making in elderly burn patients. When looking at treatment regimens currently applied in elderly burn patients, the discussion of standards in intensive care as well as surgical strategies is ongoing. However, trends towards a moderate, non-aggressive resuscitation approach and careful inclusion of key parameters like physiological age, pre-burn functional status and premorbid conditions, seem to be useful guidelines for interdisciplinary treatment decisions. Once ordered for surgical treatment, the amount of body surface area operated in one session should be adapted to the general status of the patient. Even if older burn victims have a reported higher mortality rate than younger patients, improved therapeutic options have contributed to a reduced mortality rate even in the elderly over the last decades. As a result of improved outcome, more attention has to be given to a comprehensive rehabilitation program. This review will give an overview of the current literature and will draw attention to specific topics related to this important subpopulation of burn patients.

    On the basis of the bathymetric records of 371 survey sections in the present Huanghe mouth area from 1996 to 2001, the temporal and spatial variations of the Huanghe mouth bars were studied by using GIS technology. The variation of the mouth bars is closely related to the water and sediment discharges from the Huanghe River to the sea that has been decreasing drastically in recent years, and to coastal hydrodynamic regimes. The characteristics of the mouth bars are unique in contrast with those of other estuaries in the world (1) The mouth bars of the Huanghe River consist of many small sandbars. Usually the sandbars are of ellipse-shape with the long axis of about 1~6 km, and short axis of about 1~4 kin. The long axis is parallel to the principal direction of tidal current, and the short axis is variable, depending on the local dynamics. The crest of the sandbars is only about 0.4 m below the water surface at low tide. They are distributed within an area of 20 km2, not far from the river mouth area. The present mouth bars are in small-medium size, quite different from the large one formed during the 1970s and 1980s, when the river sediment discharge was several times larger than that after 1996. (2) The scale of a river mouth bar is related to the river discharge of that year. In 1997 sediment discharge from the Huanghe River was 42 Mt, and the mouth bar consisted of several small scattered sandbars. In 1998 the size of mouth bars was much larger thar that in 1997, as the sediment discharge from the Huanghe River increased to 363 Mt. Variation of the mouth bars largely depends on the sediment discharge with a correlation coefficient of 0.78. The calculation of the volume of the mouth bar area shows that about 30%~40% of the river's into-sea sediment is deposited in the mouth bar area. (3) Compared with other large estuaries in the world, the Huanghe mouth bars have three unique features in responding to its high sediment concentration: small size, steep

    Full Text Available Word of mouth (WOM has a powerful effect on consumer behavior. Manually collecting WOM is very time-consuming in the era of the Internet. An automatic WOM recommender model is useful for both marketers and consumers. There are many different product features and thus many consumer choices. Each individual consumer has different preferences and these preferences may be changed deliberately or unwittingly. However, most existing WOM recommender models do not adapt to user preferences. This study proposes a conceptual WOM recommender model, which contains WOM collecting, document processing, recommending and user preference processing phases. More specifically, the self-organizing map (SOM is used to store and abstract user preferences. This proposed WOM model makes recommendations to consumers or users according to their adaptive preferences.

For this reason, nursing care of burn patients is very important. In this study in order to provide qualified care to the burned patients, patient and #8217;s expectations from nurses were aimed to be established. METHODS: Patients and #8217; expectations were evaluated on 101 patients with burn in Ministry of Health Ankara Numune Education and Research Hospital Burn Service and Gulhane Military Medical Academy Education and Research Hospital Burn Center. A questionnaire which was developed by the researchers was used for collecting data. The questions on the questionnaire were classified into four groups to evaluate the patients and #8217; expectations about communication, information, care and discharge. Data was evaluated by using SPSS 12 package software. RESULTS: In this study, 48.5% of patients were at 18-28 age group, 79.2% were male and 51.5% of patients were employed. Almost all of patients expect nurses to give them confidence (98% and to give them information about latest developments with the disease. Patients prior expectation from nurses about care was to do their treatments regularly (100% and to take the necessary precautions in order to prevent infection (100%. 97% of patient expect nurses to give them information about the drugs, materials and equipment that they are going to use while discharge. CONCLUSION: As a result we found that burn patient expectations from nurses about communication, information, care and discharge were high. [TAF Prev Med Bull 2014; 13(1.000: 37-46

  7. LA50 in burn injuries. (United States)

    Seyed-Forootan, K; Karimi, H; Motevalian, S A; Momeni, M; Safari, R; Ghadarjani, M


    Burn injuries put a huge financial burden on patients and healthcare systems. They are the 8th leading cause of mortality and the 13th most common cause of morbidity in our country. We used data from our Burn Registry Program to evaluate risk factors for mortality and lethal area fifty percent (LA50) in all burn patients admitted over two years. We used multiple logistic regressions to identify risk factors for mortality. LA50 is a reliable aggregate index for hospital care quality and a good measure for comparing results, also with those of other countries. 28,690 burn patients sought medical attention in the Emergency Department, and 1721 of them were admitted. Male to female ratio was 1,75:1. 514 patients were under 15 years old. Median age was 25 (range: 3 months - 93 years). Overall, probability of death was 8.4%. LA50 was 62.31% (CI 95%: 56.57-70.02) for patients aged 15 and over and 72.52% (CI 95%: 61.01-100) for those under 15. In the final model, we found that Adjusted OR was significant for age, female sex, TBSA and inhalation injury (P age and inhalation injury were the main risk factors for death. Authorities should pay special attention to these variables, especially in prevention programs, to reduce mortality and improve patient outcome. Children have better outcome than adults given equal burn size. Suicide rates are higher for women than men in our country.

  8. Telemedicine and burns: an overview. (United States)

    Atiyeh, B; Dibo, S A; Janom, H H


    Access to specialized burn care is becoming more difficult and is being restricted by the decreasing number of specialized burn centers. It is also limited by distance and resources for many patients, particularly those living in poverty or in rural medically underserved communities. Telemedicine is a rapidly evolving technology related to the practice of medicine at a distance through rapid access to remote medical expertise by telecommunication and information technologies. Feasibility of telemedicine in burn care has been demonstrated by various centers. Its use facilitates the delivery of care to patients with burn injuries of all sizes. It allows delivery of acute care and can be appropriately used for a substantial portion of the long-term management of patients after a burn by guiding less-experienced surgeons to treat and follow-up patients more appropriately. Most importantly, it allows better effective triage which reduces unnecessary time and resource demanding referrals that might overwhelm system capacities. However, there are still numerous barriers to the implementation of telemedicine, including technical difficulties, legal uncertainties, limited financial support, reimbursement issues, and an inadequate evidence base of its value and efficiency.

  9. On the Conventionalization of Mouth Actions in Australian Sign Language. (United States)

    Johnston, Trevor; van Roekel, Jane; Schembri, Adam


    This study investigates the conventionalization of mouth actions in Australian Sign Language. Signed languages were once thought of as simply manual languages because the hands produce the signs which individually and in groups are the symbolic units most easily equated with the words, phrases and clauses of spoken languages. However, it has long been acknowledged that non-manual activity, such as movements of the body, head and the face play a very important role. In this context, mouth actions that occur while communicating in signed languages have posed a number of questions for linguists: are the silent mouthings of spoken language words simply borrowings from the respective majority community spoken language(s)? Are those mouth actions that are not silent mouthings of spoken words conventionalized linguistic units proper to each signed language, culturally linked semi-conventional gestural units shared by signers with members of the majority speaking community, or even gestures and expressions common to all humans? We use a corpus-based approach to gather evidence of the extent of the use of mouth actions in naturalistic Australian Sign Language-making comparisons with other signed languages where data is available--and the form/meaning pairings that these mouth actions instantiate.

    Full Text Available A burn is a wound in which there is coagulative necrosis of the tissue, majority of which are caused by heat. Burn injury is a major public health problem in many areas of the world. Burns predispose to infection by damaging the protective barrier function of the skin, thus facilitating the entry of pa thogenic microorganisms and by inducing systemic immunosuppression . (1 OBJECTIVE : The present study was therefore undertaken to isolate and identify the aerobic bacterial flora in burn patients and its antibiotic susceptibility pattern. MATERIAL & METHODS : A total of 100 patients admitted with different degree of burns were studied. Wound swabs were taken with aseptic precautions by dry sterile cotton swab sticks. These swabs were transported to the microbiology laboratory and the isolates were identified based on standard microbiological methods. Antibiotic susceptibility testing was done by Kirby Bauer’s disc diffusion method. RESULT : A total of 127 bacterial pathogens were isolated from 100 patients. Of these, 69% were monomicrobial in nature and 28% wer e polymicrobial. The most frequent cause of infection was found to be Staphylococcus aureus (39.4%, followed by Pseudomonas aeruginosa (14.2%, Klebsiella pneumonia (13.4%, E.coli (8.7% and Acinetobacter species (7.9%.Out of the total Staphylococcus au reus isolates, 19 were Methicillin sensitive and 31 were Methicillin resistant (MRSA. All the MRSA strains were 100% sensitive to Vancomycin and Linezolid. The Pseudomonas aeruginosa isolates were most sensitive to Amikacin (9 4.4%, Fluroquinolones (61.1% . CONCLUSION : Staphylococcus aureus and Pseudomonas aeruginosa were major causes of infection in burn wounds. Therefore it is necessary to implement urgent measures for restriction of nosocomial infections, sensible limitation on the use of antimicrobial agents, strict disinfection and hygiene.

    Full Text Available With the increased usage of online technologies, there has been an escalation of Electronic Word - of –Mouth (eWOM messages related to sport products and services offered and consumed. Therefore, in this original investigation by applying eWOM to the sport industry, this study examined how the combination of the quality of the eWOM message and the provider of the eWOM message affects purchaseintentions depending on the expertise level of the consumer. This study – which involved the collection of data from 134 students at a large university situated in the Midwest of the United States – utilized repeated measures of Analysis of Variance (ANOVA with tripartite groups of expertise and experimental conditions as independent variables. Purchase intention was the dependent variables. The results indicated that the quality of the eWOM message moderated the effect of the provider of the eWOM message. The subject’s level of expertise also had a moderating role on purchase intention.

  14. Maximum opening of the mouth by mouth prop during dental procedures increases the risk of upper airway constriction

    Directory of Open Access Journals (Sweden)

    Hiroshi Ito


    Full Text Available Hiroshi Ito1, Hiroyoshi Kawaai1, Shinya Yamazaki1, Yosuke Suzuki21Division of Systemic Management, Department of Oral Function, 2Division of Radiology and Diagnosis, Department of Medical Sciences, Ohu University, Post Graduate School of Dentistry, Koriyama City, Fukushima Prefecture, JapanAbstract: From a retrospective evaluation of data on accidents and deaths during dental procedures, it has been shown that several patients who refused dental treatment died of asphyxia during dental procedures. We speculated that forcible maximum opening of the mouth by using a mouth prop triggers this asphyxia by affecting the upper airway. Therefore, we assessed the morphological changes of the upper airway following maximal opening of the mouth. In 13 healthy adult volunteers, the sagittal diameter of the upper airway on lateral cephalogram was measured between the two conditions; closed mouth and maximally open mouth. The dyspnea in each state was evaluated by a visual analog scale. In one subject, a computed tomograph (CT was taken to assess the three-dimensional changes in the upper airway. A significant difference was detected in the mean sagittal diameter of the upper airway following use of the prop (closed mouth: 18.5 ± 3.8 mm, maximally open mouth: 10.4 ± 3.0 mm. All subjects indicated upper airway constriction and significant dyspnea when their mouth was maximally open. Although a CT scan indicated upper airway constriction when the mouth was maximally open, muscular compensation was admitted. Our results further indicate that the maximal opening of the mouth narrows the upper airway diameter and leads to dyspnea. The use of a prop for the patient who has communication problems or poor neuromuscular function can lead to asphyxia. When the prop is used for patient refusal in dentistry, the respiratory condition should be monitored strictly, and it should be kept in mind that the “sniffing position” is effective for avoiding upper airway

The management can be challenging because clinical presentation and severity of these burns vary widely. Plastic surgeons managing burn patients must have a basic understanding of the pathophysiology, the range of severity in presentation and the current treatment options available for HF burns. The present article reviews the current understanding of the pathophysiology and systemic effects associated with severe HF burns. Furthermore, it distinguishes between minor and life-threatening HF burns and describes several of the basic techniques that are available to treat patients with HF burns.

  2. MHD control in burning plasmas MHD control in burning plasmas (United States)

    Donné, Tony; Liang, Yunfeng


    Fusion physics focuses on the complex behaviour of hot plasmas confined by magnetic fields with the ultimate aim to develop a fusion power plant. In the future generation of tokamaks like ITER, the power generated by the fusion reactions substantially exceeds the external input power (Pfusion}/Pin >= 10). When this occurs one speaks of a burning plasma. Twenty per cent of the generated fusion power in a burning plasma is carried by the charged alpha particles, which transfer their energy to the ambient plasma in collisions, a process called thermalization. A new phenomenon in burning plasmas is that the alpha particles, which form a minority but carry a large fraction of the plasma kinetic energy, can collectively drive certain types of magneto-hydrodynamic (MHD) modes, while they can suppress other MHD modes. Both types of MHD modes can have desirable effects on the plasma, as well as be detrimental to the plasma. For example, the so-called sawtooth instability, on the one hand, is largely responsible for the transport of the thermalized alpha particles out of the core, but, on the other hand, may result in the loss of the energetic alphas before they have fully thermalized. A further undesirable effect of the sawtooth instability is that it may trigger other MHD modes such as neoclassical tearing modes (NTMs). These NTMs, in turn, are detrimental to the plasma confinement and in some cases may even lead to disruptive termination of the plasma. At the edge of the plasma, finally, so-called edge localized modes or ELMs occur, which result in extremely high transient heat and particle loads on the plasma-facing components of a reactor. In order to balance the desired and detrimental effects of these modes, active feedback control is required. An additional complication occurs in a burning plasma as the external heating power, which is nowadays generally used for plasma control, is small compared to the heating power of the alpha particles. The scientific challenge

    Felcar, Josiane Marques; Bueno, Izabele Rafael; Massan, Ana Carolina Silva; Torezan, Roberta Pereira; Cardoso, Jefferson Rosa


    The objective of this article is to identify the prevalence of mouth breathing in children from an elementary school. 496 questionnaires were answered by 1st and 4th grade children's parents or sponsors in order to identify mouth-breathing. There were questions about habits, sleeping, behavior, eating, personal care and breathing. Mann-Whitney and the Chi-square tests were used to compare the variables between mouth-breathing and nose-breathing among the groups. To measure the exposure effect of the explanatory variables on mouth breathing, the test of logistic regression was used and its magnitude was calculated through Odds Ratio. The statistical significance was set at 5%, and the rate of returned questionnaires was 84.5%. The prevalence of the mouthbreathing over this population was 56.8%. The average age was 7 years old (6-9). There was no significant statistical difference between genders, considering 49.1% male and 50.9% female. The final model of logistic regression identified the variables dribble, sleeps well (negative association) and snores as factors that predict the occurrence of the mouth-breathing. The prevalence of mouthbreathing was similar to related in the literature. The variables dribble, sleeps well (negative association) and snores may be factors that predict the occurrence of mouth-breathing.

  4. [Oral medicine 1. Causes and clinical symptoms of dry mouth]. (United States)

    Vissink, A; Visser, A; Spijkervet, F K L


    Healthcare providers do not always recognize dry mouth and the problems associated with it. The symptoms of dry mouth and the patterns of complaints associated with it are the feeling that the mouth is dry; foamy or very watery saliva; a red appearance of the mucosa under a denture and the excessive presence of remaining food particles on the mucosa or the denture. The most serious detrimental aspect of dry mouth complaints is a reduced secretion of saliva, but afeeling ofa dry mouth can also exist without an objectively assessed hyposalivation. The most important causes of dry mouth are the side effects ofmedications, systemic diseases, radiotherapy in the head and neck region and occasionally a psychiatric disorder. Early recognition of the symptoms and the establishment ofa precise diagnosis are essential for proper treatment and for optimizing the quality of life of the patient. Basic investigation consists of an extensive patient history, inspection of the head and neck region and the oral cavity, evaluation ofthefunctioning of the salivary glands, and, if necessary, additional investigations.

Injuries related to titanium tetrachloride should be treated seriously and accordingly appropriate management is suggested.

  7. A review of hydrofluoric acid burn management


    McKee, Daniel; Thoma, Achilleas; Bailey, Kristy; Fish, Joel


    The clinical presentation and severity of hydrofluoric acid burns vary considerably, making management particularly challenging. Given that current knowledge of HF burns is derived from small case series, case reports, animal studies and anecdotal evidence, this narrative review discusses the current understanding of the effects associated with severe hydrofluoric acid burns, describing the mechanism of injury, systemic toxicity and treatment options.

  8. New type of sauna-related burn: conductive contact burn. (United States)

    Shin, Seung Jun; Yoo, Heon; Park, Myong Chul


    A 70-year-old woman visited a Korean-style hot dry sauna room. The patient had a medical history of hypertension and hyperlipidemia. During the sauna, the patient slept for 30 minutes. During the sleep, the right medial thigh was covered with a fully wet towel. The patient sustained a second-degree burn on the right medial thigh area with multiple bullas. On physical examination, erythema, heating sensation, and swelling around the bullas were noted. The patient was admitted and received intravenous antibiotics for 7 days. A dressing with Silmazine 1% cream (sulfadiazine) was applied twice a day for prevention of local infection. The patient was discharged on day 14 without complication. In this case, the mechanism of the burn was different. Hot air has much thermal energy but is not conducted to the skin directly. A wet towel will have a relatively higher thermal capacity or heat capacity than a dry or damp towel, and the sodden water might be a medium for the conduction of thermal energy. Owing to the global popularity of sauna bathing, it is important to recognize all sources of sauna-related burns.

    Full Text Available The simulation of current and projected wildfires is essential for predicting crucial aspects of vegetation patterns, biogeochemical cycling as well as pyrogenic emissions across the African continent. This study uses a data-driven approach to parameterize two burned area models applicable to dynamic vegetation models (DVMs and Earth system models (ESMs. We restricted our analysis to variables for which either projections based on climate scenarios are available, or that are calculated by DVMs, and we consider a spatial scale of one degree as the scale typical for DVMs and ESMs. By using the African continent here as an example, an analogue approach could in principle be adopted for other regions, for global scale dynamic burned area modelling.

    We used 9 years of data (2000–2008 for the variables: precipitation over the last dry season, the last wet season and averaged over the last 2 years, a fire-danger index (the Nesterov index, population density, and annual proportion of area burned derived from the MODIS MCD45A1 product. Two further variables, tree and herb cover were only available for 2001 as a remote sensing product. Since the effect of fires on vegetation depends strongly on burning conditions, the timing of wildfires is of high interest too, and we were able to relate the seasonal occurrence of wildfires to the daily Nesterov index.

    We parameterized two generalized linear models (GLMs, one with the full variable set (model VC and one considering only climate variables (model C. All introduced variables resulted in an increase in model performance. Model VC correctly predicts the spatial distribution and extent of fire prone areas though the total variability is underrepresented. Model VC has a much lower performance in both aspects (correlation coefficient of predicted and observed ratio of burned area: 0.71 for model VC and 0.58 for model C. We expect the remaining variability to be attributed to additional

    Full Text Available The hand is ranked among the three most frequent sites of burns scar contracture deformity. One of the major determinants of the quality of life in burns survivors is the functionality of the hands. Burns deformities, although largely preventable, nevertheless do occur when appropriate treatment is not provided in the acute situation or when they are part of a major burns. Reconstructive procedures can greatly improve the function of the hands. Appropriate choice of procedures and timing of surgery followed by supervised physiotherapy can be a boon for a burns survivor.

    Full Text Available Burn injuries are a huge public health issue for children throughout the world, with the majority occurring in developing countries. Burn injuries can leave a pediatric patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Rehabilitation is an essential and integral part of pediatric burn treatment. The aim of this article was to review the literature on pediatric burn rehabilitation from the Medline, CINAHL, and Web of Science databases. An attempt has been made to present the basic aspects of burn rehabilitation, provide practical information, and discuss the goals and conceptualization of rehabilitation as well as the development of rehabilitation philosophy and strategies.

    Full Text Available In 2009, the Victoria Department of Sustainability and Environment estimated approximately 430,000 hectares of Victoria Australia were burned by numerous bushfires. Burned Area Emergency Response (BAER teams from the United States were deployed to Victoria to assist local fire managers. The U.S. Geological Survey Earth Resources Observation and Science Center (USGS/EROS and U.S. Forest Service Remote Sensing Applications Center (USFS/RSAC aided the support effort by providing satellite-derived "soil burn severity " maps for over 280,000 burned hectares. In the United States, BAER teams are assembled to make rapid assessments of burned lands to identify potential hazards to public health and property. An early step in the assessment process is the creation of a soil burn severity map used to identify hazard areas and prioritize treatment locations. These maps are developed primarily using Landsat satellite imagery and the differenced Normalized Burn Ratio (dNBR algorithm.

  13. [Current treatment strategies for paediatric burns]. (United States)

    Küntscher, M V; Hartmann, B


    Paediatric burns occupy the third place in the severe accident statistics in Germany after traffic injuries and drowning. The paper reviews current treatment concepts of pre-hospital management, fluid resuscitation and surgical therapy in paediatric burned patients. Specific features in the approximation of the total body surface area burn and indications for transfer of paediatric burn victims to specialized units are discussed. The therapy of severe paediatric burns requires an interdisciplinary team consisting of especially skilled plastic or paediatric surgeons,anaesthetists, psychiatrists or psychologists, specifically trained nurses, physiotherapists and social workers. The rehabilitation process starts basically with admission to the burn unit. A tight cooperation between therapists and the relatives of the paediatric burn victim is needed for psychological recovery and reintegration into society.'The adaptation to the suffered trauma resulting in life-long disability and disfigurement is the main task of psychotherapy.

  14. Septicemia: The Principal Killer of Burns Patients

    Directory of Open Access Journals (Sweden)

    B. R. Sharma


    Full Text Available Burn injury is a major problem in many areas of the world and it has been estimated that 75% of all deaths following burns are related to infection. Burns impair the skin’s normal barrier function thus allowing microbial colonization of the burn wounds and even with the use of topical antimicrobial agents, contamination is almost unavoidable. It is therefore essential for every burn institution to determine its specific pattern of burn wound microbial colonization, time related changes in predominant flora and antimicrobial resistance profiles. This would allow early management of septic episodes with proper empirical systemic antibiotics before the results of microbiologic culture becomes available, thus improving the overall infection-related morbidity and mortality. We attempted to examine the factors affecting risk of infection; strategies for infection control and prevention in burn victims.

  15. Zinc supplementation in burn patients. (United States)

    Caldis-Coutris, Nancy; Gawaziuk, Justin P; Logsetty, Sarvesh


    Micronutrient supplementation is a common practice throughout many burn centers across North America; however, uncertainty pertaining to dose, duration, and side effects of such supplements persists. The authors prospectively collected data from 23 hospitalized patients with burn sizes ranging from 10 to 93% TBSA. Each patient received a daily multivitamin and mineral supplement, 50 mg zinc (Zn) daily, and 500 mg vitamin C twice daily. Supplements were administered orally or enterally. Albumin, prealbumin, C-reactive protein, serum Zn, and serum copper were measured weekly during hospital admission until levels were within normal reference range. Our study concluded that 50 mg daily dose of Zn resulted in normal serum levels in 19 of 23 patients at discharge; 50 mg Zn supplementation did not interfere with serum copper levels; and Zn supplements, regardless of administration route, did not result in gastrointestinal side effects.

  16. Southeast U.S. burns (United States)

    Maggs, William Ward

    Human beings were responsible for most of 12,000 forest fires in the southeastern United States that burned for 10 days in late October and early November 1987. 910 km2, mostly hardwood forest, were destroyed in the fires, with arson and carelessness as the primary causes, according to the U.S. Department of Agriculture Forest Service.Measured in monetary terms, the toll was more than $40 million in resource and property damage. While the amount of forest burned did not rival the 3390 km2 lost to fires in the western United States last summer, the human impact was severe in the southeast and all along the East Coast. Favorable winds blew smoke from the southern and central Appalachians as far north as New England and as far east as Delaware, and cool fall air close to the ground prevented the smoke from rising, thickening the air in many northeastern cities on November 8 and 9.

  17. Fluconazole Pharmacokinetics in Burn Patients (United States)

    Boucher, Bradley A.; King, Stephen R.; Wandschneider, Heidi L.; Hickerson, William L.; Hanes, Scott D.; Herring, Vanessa L.; Canada, Todd W.; Hess, Mary M.


    The pharmacokinetics of fluconazole in nine adult patients with severe (30 to 95% total body surface area) burns were studied. There was no significant difference in half-life (t1/2), clearance (CL), or volume of distribution (V) over time in five patients on days 3 and 8 of the study (P > 0.05). Combined parameter estimates (means ± standard deviations) for all nine patients for the two study periods were as follows: t1/2, 24.4 ± 5.8 h; CL, 0.36 ± 0.09 ml/min/kg; and V, 0.72 ± 0.12 liters/kg. These estimates of t1/2 and CL in burn patients were approximately 13% shorter and 30% more rapid, respectively, than the most extreme estimates reported for other populations. PMID:9559811

    Foyatier, J L; Latarjet, J; Comparin, J P; Zaragori, M; Robert, A; Braye, F; Weill, E; Masson, C L


    Because of the potential severity of their residual deformities, burn injuries in infants justify an early management in specialized centres when they cover more than 5% of body surface and in every case when hands, face, or external genitalia are concerned. Cooling with cold water is the first aid treatment to be performed as early as possible after the injury. The treatment in specialized centres must be both general and surgical. General treatment includes fluid and electrolyte therapy, temperature control, appropriate nutrition and pain suppression. Pain suppression is a major part of the treatment and morphine must be largely used. Surgical treatment starts as soon as the patient arrives in the centre and is eventually performed under general anesthesia: all the burned areas are covered with occlusive dressings. Infections are prevented by systematic cultures and adjusted antibiotic therapy. A vigorous rehabilitation program must be instituted as soon as possible: massages, compressive clothes, splints, physical therapy, plastic surgery. Primary prevention by sustained parental education is important in order to reduce the frequency of burn injuries in infants.

  1. Association between oral habits, mouth breathing and malocclusion. (United States)

    Grippaudo, C; Paolantonio, E G; Antonini, G; Saulle, R; La Torre, G; Deli, R


    The ratio of bad habits, mouth breathing and malocclusion is an important issue in view of prevention and early treatment of disorders of the craniofacial growth. While bad habits can interfere with the position of the teeth and normal pattern of skeletal growth, on the other hand obstruction of the upper airway, resulting in mouth breathing, changes the pattern of craniofacial growth causing malocclusion. Our crosssectional study, carried out on 3017 children using the ROMA index, was developed to verify if there was a significant correlation between bad habits/mouth breathing and malocclusion. The results showed that an increase in the degree of the index increases the prevalence of bad habits and mouth breathing, meaning that these factors are associated with more severe malocclusions. Moreover, we found a significant association of bad habits with increased overjet and openbite, while no association was found with crossbite. Additionally, we found that mouth breathing is closely related to increased overjet, reduced overjet, anterior or posterior crossbite, openbite and displacement of contact points. Therefore, it is necessary to intervene early on these aetiological factors of malocclusion to prevent its development or worsening and, if already developed, correct it by early orthodontic treatment to promote eugnatic skeletal growth.

  2. Symbiotic symbolization by hand and mouth in sign language. (United States)

    Sandler, Wendy


    Current conceptions of human language include a gestural component in the communicative event. However, determining how the linguistic and gestural signals are distinguished, how each is structured, and how they interact still poses a challenge for the construction of a comprehensive model of language. This study attempts to advance our understanding of these issues with evidence from sign language. The study adopts McNeill's criteria for distinguishing gestures from the linguistically organized signal, and provides a brief description of the linguistic organization of sign languages. Focusing on the subcategory of iconic gestures, the paper shows that signers create iconic gestures with the mouth, an articulator that acts symbiotically with the hands to complement the linguistic description of objects and events. A new distinction between the mimetic replica and the iconic symbol accounts for the nature and distribution of iconic mouth gestures and distinguishes them from mimetic uses of the mouth. Symbiotic symbolization by hand and mouth is a salient feature of human language, regardless of whether the primary linguistic modality is oral or manual. Speakers gesture with their hands, and signers gesture with their mouths.

    Mohammadreza Majidi


    Full Text Available Introduction: Nasal septal deviation and hypertrophy of the adenoids and palatine tonsils are two common causes of nasopharyngeal obstruction and consequently mouth breathing in children. It is accepted that chronic mouth breathing influences craniofacial growth and development. The aim of this study was to evaluate the differences of craniofacial morphology in children with two different etiological factors of mouth breathing. Materials and Methods: Study design: cross sectional. The research was conducted between 2005-2007 on 47 predominantly mouth breathing patients aged 6-10 years. After otorhinolaryngologic examination, patients were divided into two groups based on the etiology of nasopharyngeal obstruction: group 1, with Adenoid hypertrophy and group 2 with nasal septal deviation. Lateral cephalometric radiographs were obtained to assess craniofacial development. Data gained were statistically evaluated by Mann-Whitney and T-student tests. Results: With respect to the inclination of the mandibular and palatal planes, anteroposterior relationship of maxilla and mandible to the cranial base, and indexes of facial height proportions, no significant differences were observed between two groups of children with mouth breathing. Only the gonial and craniocervical angle measurements were significantly larger in children with adenoid hypertrophy (P

    Because of their extensive wounds, burn patients are chronically exposed to inflammatory mediators. Thus, burn patients, by definition, already have "systemic inflammatory response syndrome." Current definitions for sepsis and infection have many criteria (fever, tachycardia, tachypnea, leukocytosis) that are routinely found in patients with extensive burns, making these current definitions less applicable to the burn population. Experts in burn care and research, all members of the American Burn Association, were asked to review the literature and prepare a potential definition on one topic related to sepsis or infection in burn patients. On January 20, 2007, the participants met in Tucson, Arizona to develop consensus for these definitions. After review of the definitions, a summary of the proceedings was prepared. The goal of the consensus conference was to develop and publish standardized definitions for sepsis and infection-related diagnoses in the burn population. Standardized definitions will improve the capability of performing more meaningful multicenter trials among burn centers.

    Twelve water samples were collected and analyzed. The samples were taken from the river mouths around Bohai Bay including the Jiyun, New Yongding, Haihe, Dagu, Duliujian, Qingjinghuang, Qikou, Dakou, and Yellow Rivers, and tested for concentrations of heavy metals, arsenic, total nitrogen (TN) and total phosphorus (TP). The results show that the river mouths are polluted and the water quality exceeds Class V of the Environmental Quality Standard for Surface Water (EQSSW). The main pollutants are Hg, nitrogen (N) and phosphorus (P). The concentrations of the other pollutants are within Class Ⅱ of the Standard. The Hg content in the Haihe River mouth is now 10 times higher than it was 20 years ago, indicating that the accelerating water pollution has reached an alarming level. The high concentrations of N and P cause eutrophication of the waters.Analysis indicates that the terrestrial pollutants and nutrients are the main cause of frequently occurring red tides in the Bohai Sea.

    Full Text Available Since the development of Web 2.0 (or social media sites such as Facebook, Twitter, Blogger, and various forums and communities, online users from all over the world have been exposed to a completely new means of information sharing: electronic word of mouth (e-WOM. Due to the fact that it is a recent research phenomenon, its definition is difficult to be phrased and similar to traditional word-of-mouth, the theoretical framework of e-WOM is not very clear. This complex concept is linked to viral marketing, user generated content, stealth marketing, opinion sharing, decision making and other aspects. Considering the multiple areas that e-WOM has an influence on, this article presents an overview of what has been researched with respect to this subject. Using the findings of this paper, it may be possible to set up the base of a conceptual model to measure electronic word of mouth.

    Full Text Available Systemic sclerosis (SSc is a relatively rare condition with an immunologically mediated pathogenesis. For reasons that are not clearly understood, dense collagen is deposited in the connective tissues of the body in extraordinary amounts. Although its dramatic effects are seen in association with the skin, the disease is often quite serious with visceral organ involvement. We describe a case of limited mouth opening secondary to diffuse SSc, improvement in mouth opening with passive jaw stretch exercises, and the challenges involved in performing dental procedures for such patients.

    Haberal Mehmet


    Full Text Available It is a widely accepted fact that severe fluid loss is the greatest problem faced following major burn injuries. Therefore, effective fluid resuscitation is one of the cornerstones of modern burn treatment. The aim of this article is to review the current approaches available for modern trends in fluid management for major burn patients. As these current approaches are based on various experiences all over the world, the knowledge is essential to improve the status of this patient group.

  16. Infection control in severely burned patients


    Coban, Yusuf Kenan


    In the last two decades, much progress has been made in the control of burn wound infection and nasocomial infections (NI) in severely burned patients. The continiually changing epidemiology is partially related to greater understanding of and improved techniques for burn patient management as well as effective hospital infection control measures. With the advent of antimicrobial chemotherapeutic agents, infection of the wound site is now not as common as, for example, urinary and blood strea...

  17. Managing burn patients in a fire disaster: Experience from a burn unit in Bangladesh

    Directory of Open Access Journals (Sweden)

    Mashreky S


    Full Text Available Although burn disaster is not a frequent event, with urbanisation and industrialisation, burn disaster is becoming an emerging problem in Bangladesh. On 3 June 2010, a fire disaster killed 124 people in Neemtali, Dhaka, Bangladesh. This paper narrates the management of burn patients of this disaster in the burn unit of Dhaka Medical College Hospital. The burn unit managed 192 burn victims of the disaster. Forty-two victims were admitted and 150 of them received primary care at the emergency room and were sent back home. Ten patients among 42 in-patients died. The in-patient mortality was 23.8%. Burn unit in Dhaka Medical College Hospital is the only burn management centre in Bangladesh. Proper planning and coordinated effort by all sectors and persons concerned were the key elements in this successful management.

  18. Renal failure in burn patients: a review. (United States)

    Emara, S S; Alzaylai, A A


    Burn care providers are usually challenged by multiple complications during the management of acute burns. One of the most common complications worldwide is renal failure. This article reviews the various aspects of renal failure management in burn patients. Two different types of renal failures develop in these patients. The different aetiological factors, incidence, suspected prognosis, ways of diagnosing, as well as prevention methods, and the most accepted treatment modalities are all discussed. A good understanding and an effective assessment of the problem help to reduce both morbidity and mortality in burn management.

  20. Hospital costs associated with pediatric burn injury. (United States)

    Klein, Matthew B; Hollingworth, William; Rivara, Frederick P; Kramer, C Bradley; Askay, Shelley W; Heimbach, David M; Gibran, Nicole S


    Modern burn care is a resource intensive endeavor requiring specialized equipment, personnel, and facilities in order to provide optimum care. The costs associated with burn injury to both patients and society as a whole can be multifaceted and large. The purpose of this study was to evaluate the association between hospital costs, patient characteristics, and injury factors in a cohort of pediatric patients admitted to a regional burn center. We performed a review of the hospital charges accrued by pediatric patients (age dollar costs using an inflation index and a cost to charge ratio. Univariate and multivariate regressions were performed to identify the factors most significantly associated with cost. In addition, we performed a subset cost analysis for patients with burns more than 20% TBSA. A total of 1443 pediatric patients (age dollars was dollars 9026 (SD = dollars 25,483; median = dollars 2138). Area of full thickness burn was the only patient or injury factor significantly associated with greater hospital costs (P < .05) on multivariate analysis. No single anatomic area was associated with increased hospital costs when adjusted for total overall burn size. Injury severity was the most significant factor impacting index hospitalization costs following pediatric burn injury. Further studies defining the long-term societal costs impact of burn injury are needed as are studies that evaluate the impact of burn injury on quality of life.

  1. Aeromonas hydrophila in a burn patient. (United States)

    Yasti, Ahmet Cinar; Otan, Emrah; Doganay, Mutlu; Kama, Nuri A


    Infectious consequences are still a major problem and leading cause of mortality in burn patients. Among others, aeromonads need special concern because they mimic pseudomonal infections; however, they have a more rapid progression with considerable mortality if undiagnosed promptly. Here, we present a major burn case extinguished with tap water pooled in a tank. With the possibility of aeromonal infection in mind, the patient underwent aggressive debridement with proper antibiotic medication, which resulted in a successful patient management. Aeromonads should always be kept in mind in burn cases that contacted with tanked water or soil after the burn.

  2. Burn healing plants in Iranian Traditional Medicine

    Directory of Open Access Journals (Sweden)

    Sh. Fahimi


    Full Text Available Burns are known as one of the most common forms of injury with devastating consequences. Despite the discovery of several antiseptics, burn wound healing has still remained a challenge to modern medicine. Herbal products seem to possess moderate efficacy with no or less toxicity and are less expensive compared to synthetic drugs. Burn is a well-known disorder in Iranian Traditional Medicine (ITM. Iranian physicians have divided burns into various types based on the cause and recommended treatment for each type. According to ITM references, herbal therapy was the major treatment prescribed by Iranian physicians for burns. In the present study, seven ancient Iranian medical texts were screened for the herbs with burn healing effects along with their applied dosage forms. The medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the best scientific name that was suitable for each plant as well as surveying modern studies about their biological effects has been carried out. In our investigation eighteen plants with seven topical application categories have been obtained as the most frequent herbs for burn healing in ITM. Modern studies have revealed that these plants have shown some biological activities such as anti-inflammatory, antimicrobial and antioxidant effects which might establish the relationship between the mentioned activities and burn wound healing property. This list can provide a suitable resource for future researches in the field of burn treatment.

  3. Patient safety measures in burn care: do National reporting systems accurately reflect quality of burn care? (United States)

    Mandell, Samuel P; Robinson, Ellen F; Cooper, Claudette L; Klein, Matthew B; Gibran, Nicole S


    Recently, much attention has been placed on quality of care metrics and patient safety. Groups such as the University Health-System Consortium (UHC) collect and review patient safety data, monitor healthcare facilities, and often report data using mortality and complication rates as outcomes. The purpose of this study was to analyze the UHC database to determine if it differentiates quality of care across burn centers. We reviewed UHC clinical database (CDB) fields and available data from 2006 to 2008 for the burn product line. Based on the September 2008 American Burn Association (ABA) list of verified burn centers, we categorized centers as American Burn Association-verified burn centers, self-identified burn centers, and other centers that are not burn units but admit some burn patients. We compared total burn admissions, risk pool, complication rates, and mortality rates. Overall mortality was compared between the UHC and National Burn Repository. The UHC CDB provides fields for number of admissions, % intensive care unit admission, risk pool, length of stay, complication profiles, and mortality index. The overall numbers of burn patients in the database for the study period included 17,740 patients admitted to verified burn centers (mean 631 admissions/burn center/yr or per 2 years), 10,834 for self-identified burn centers (mean 437 admissions/burn center/yr or per 2 years), and 1,487 for other centers (mean 11.5 admissions/burn center/yr or per 2 years). Reported complication rates for verified burn centers (21.6%), self-identified burn centers (21.3%), and others (20%) were similar. Mortality rates were highest for self-identified burn centers (3.06%), less for verified centers (2.88%), and lowest for other centers (0.74%). However, these outcomes data may be misleading, because the risk pool criteria do not include burn-specific risk factors, and the inability to adjust for injury severity prevents rigorous comparison across centers. Databases such as the

  4. Deciding Where to Burn: Stakeholder Priorities for Prescribed Burning of a Fire-Dependent Ecosystem

    Directory of Open Access Journals (Sweden)

    Jennifer K. Costanza


    Full Text Available Multiagency partnerships increasingly work cooperatively to plan and implement fire management. The stakeholders that comprise such partnerships differ in their perceptions of the benefits and risks of fire use or nonuse. These differences inform how different stakeholders prioritize sites for burning, constrain prescribed burning, and how they rationalize these priorities and constraints. Using a survey of individuals involved in the planning and implementation of prescribed fire in the Onslow Bight region of North Carolina, we examined how the constraints and priorities for burning in the longleaf pine (Pinus palustris ecosystem differed among three stakeholder groups: prescribed burn practitioners from agencies, practitioners from private companies, and nonpractitioners. Stakeholder groups did not differ in their perceptions of constraints to burning, and development near potentially burned sites was the most important constraint identified. The top criteria used by stakeholders to decide where to burn were the time since a site was last burned, and a site's ecosystem health, with preference given to recently burned sites in good health. Differences among stakeholder groups almost always pertained to perceptions of the nonecological impacts of burning. Prescribed burning priorities of the two groups of practitioners, and particularly practitioners from private companies, tended to be most influenced by nonecological impacts, especially through deprioritization of sites that have not been burned recently or are in the wildland-urban interface (WUI. Our results highlight the difficulty of burning these sites, despite widespread laws in the southeast U.S. that limit liability of prescribed burn practitioners. To avoid ecosystem degradation on sites that are challenging to burn, particularly those in the WUI, conservation partnerships can facilitate demonstration projects involving public and private burn practitioners on those sites. In summary

  5. Medical management of paediatric burn injuries: best practice. (United States)

    Kim, Leo K P; Martin, Hugh C O; Holland, Andrew J A


    Burns commonly occur in children and their first aid remains inadequate despite burn prevention programmes. While scald injuries predominate, contact and flame burns remain common. Although typically less severe injuries overall than those in adults, hypertrophic scarring complicating both the burn wound and even donor sites occur more frequently in children. The heterogeneous nature of burn wounds, coupled with the difficulties associated with the early clinical assessment of burn depth, has stimulated the application of novel technologies to predict burn wound outcome. This review explores current best practice in the management of paediatric burns, with a focus on prevention, optimal first aid, resuscitation, burn wound prediction and wound management strategies.

  6. Sources of debris flow material in burned areas (United States)

    Santi, P.M.; deWolfe, V.G.; Higgins, J.D.; Cannon, S.H.; Gartner, J.E.


    The vulnerability of recently burned areas to debris flows has been well established. Likewise, it has been shown that many, if not most, post-fire debris flows are initiated by runoff and erosion and grow in size through erosion and scour by the moving debris flow, as opposed to landslide-initiated flows with little growth. To better understand the development and character of these flows, a study has been completed encompassing 46 debris flows in California, Utah, and Colorado, in nine different recently burned areas. For each debris flow, progressive debris production was measured at intervals along the length of the channel, and from these measurements graphs were developed showing cumulative volume of debris as a function of channel length. All 46 debris flows showed significant bulking by scour and erosion, with average yield rates for each channel ranging from 0.3 to 9.9??m3 of debris produced for every meter of channel length, with an overall average value of 2.5??m3/m. Significant increases in yield rate partway down the channel were identified in 87% of the channels, with an average of a three-fold increase in yield rate. Yield rates for short reaches of channels (up to several hundred meters) ranged as high as 22.3??m3/m. Debris was contributed from side channels into the main channels for 54% of the flows, with an average of 23% of the total debris coming from those side channels. Rill erosion was identified for 30% of the flows, with rills contributing between 0.1 and 10.5% of the total debris, with an average of 3%. Debris was deposited as levees in 87% of the flows, with most of the deposition occurring in the lower part of the basin. A median value of 10% of the total debris flow was deposited as levees for these cases, with a range from near zero to nearly 100%. These results show that channel erosion and scour are the dominant sources of debris in burned areas, with yield rates increasing significantly partway down the channel. Side channels are

    Houshang Taghizadeh


    Full Text Available Today, customer satisfaction is an important issue for organizations. Being a winner or loser is based on the percentage of customers that they have retained. This is why many scholars and researchers have continually stressed the importance of customer satisfaction. On the other hand, customer is one of the most important stakeholders in any organization because, without the customer, the organization probably will not succeed. So a customer behavioral intentions and responses, is one of the main concepts in the marketing literature has been studied. The objective of the study was to investigate the effect of customer satisfaction on word of mouth communication. Data were collected with questionnaire instruments. Model was developed and tested with structural equation model using data collected from the 412 Iranian bank customers. The results show that employee competence has a negative effect on word of mouth communication. Reliability has a positive effect on word of mouth communication and physical evidence has positive effect on word of mouth communication.

    Ana Carolina Cardoso de Melo


    Full Text Available INTRODUCTION: When there is a change in the physiological pattern of nasal breathing, mouth breathing may already be present. The diagnosis of mouth breathing is related to nasal patency. One way to access nasal patency is by acoustic rhinometry.OBJECTIVE: To systematically review the effectiveness of acoustic rhinometry for the diagnosis of patients with mouth breathing.METHODS: Electronic databases LILACS, MEDLINE via PubMed and Bireme, SciELO, Web of Science, Scopus, PsycInfo, CINAHL, and Science Direct, from August to December 2013, were consulted. 11,439 articles were found: 30 from LILACS, 54 from MEDLINE via Bireme, 5558 from MEDLINE via PubMed, 11 from SciELO, 2056 from Web of Science, 1734 from Scopus, 13 from PsycInfo, 1108 from CINAHL, and 875 from Science Direct. Of these, two articles were selected.RESULTS: The heterogeneity in the use of equipment and materials for the assessment of respiratory mode in these studies reveals that there is not yet consensus in the assessment and diagnosis of patients with mouth breathing.CONCLUSION: According to the articles, acoustic rhinometry has been used for almost twenty years, but controlled studies attesting to the efficacy of measuring the geometry of nasal cavities for complementary diagnosis of respiratory mode are warranted.

  3. Children's exposure to polybrominated diphenyl ethers (PBDEs) through mouthing toys. (United States)

    Ionas, Alin C; Ulevicus, Jocelyn; Gómez, Ana Ballesteros; Brandsma, Sicco H; Leonards, Pim E G; van de Bor, Margot; Covaci, Adrian


    Polybrominated diphenyl ethers (PBDEs) have previously been detected in children toys, yet the risk of child exposure to these chemicals through the mouthing of toys or other items is still unknown. We aimed to expand on the current knowledge by investigating the impact of infants' mouthing activities on exposure to PBDEs present in toys. This was established by a leaching model for determining the amount PBDEs that can leach from toys into saliva in simulated conditions. The PBDE migration rate was at its highest for the 15 min low-exposure scenario incubations (198 pg/cm(2) × min) with the ERM EC-591 certified reference material (CRM) (0.17% w/w PBDEs). The leaching process was congener-dependent, since the percentage of lower brominated PBDE congeners that leached out was up to 4.5 times higher than for the heavier PBDEs. To study the scenario in which a child would mouth on a toy flame retarded with BDE 209 alone, a plastic item containing 7% BDE 209 (w/w) was also tested. The BDE 209 amounts leached out in only 15 min were higher than the amounts leached from the CRM after the 16 h incubation. For the Belgian population, the exposure scenario from mouthing on toys containing PBDEs in amounts similar to the REACH threshold was found to be lower than the exposure from mother's milk, but higher than the exposure through diet or even dust.

  4. Hydrodynamic Aspects at Vitória Bay Mouth, ES

    Directory of Open Access Journals (Sweden)



    Full Text Available Understading the hydrodynamic behavior and suspended particulated matter (SPM transport are of great importance in port regions such as Vitória Harbor, which is located at Vitória Bay, Vitória – ES, Brazil. Vitória Bay is an estuary that has not been systematically assessed through a temporal analysis in order to identify its hydrodynamics characteristics and SPM exchange. This study aims to investigate salt and suspended particulate matter flux at the estuarine mouth of Vitória Bay by understanding the temporal variation of salinity, temperature and tidal currents within the water column and at the channel crosssection. Results showed that the estuarine mouth tended to present partial stratification periods during neap tides and little stratification in spring tides. The circulation pattern was mainly influenced by the tide, with little influence from river discharge. With regard to the SPM, the mouth of the estuary tended to show low concentrations, with the highest values occurring during the dry season. A close relationship between momentary discharge, SPM and salt fluxes was observed. Despite all the data was collected at the mouth of the estuary, the system showed an importation trend of salt in all cycles and SPM importation for three of the four studied tidal cycles. Thus, Vitoria Bay is not exporting SPM to the adjacent inner shelf.

    Full Text Available A 35-year-old male farmer came in contact with 11,000 volts high tension electric wire and sustained full thickness burn wounds over scapula, upper limb and anterior abdominal wall along with perforation of the intestine. Patient was initially managed conservatively in general surgery ward and was referred to us after 3 days with necrosis of the burned skin and muscles over the shoulder and abdomen. Patient was initially managed conservatively and then thorough debridement of the necrotic skin over the left shoulder and upper arm was done and the area was split skin grafted. Patient developed enterocutaneous fistula, which healed over a period of 8 weeks. The granulating wound over the abdomen was also skin grafted and patient was discharged after 18 days. About 4 months, after the discharge patient presented with ventral hernia. Repair of ventral hernia by synthetic mesh application and reconstruction of the abdominal wall with a free tensor fascia lata flap was done over the mesh, but the flap failed. Then after debridement two random pattern transposition skin flaps, one from the right upper and another from the left lower abdomen were transposed over the abdominal wound and donor area was skin grafted. Patient was discharged after 17 days.

  6. Survey of care and evaluation of East African burn unit feasibility: an academic burn center exchange. (United States)

    Mitchell, Katrina B; Giiti, Geofrey; Gallagher, James J


    Weill Cornell Medical College in New York, partnered with Weill Bugando Medical College and Sekou Toure Regional Referral Hospital, in Mwanza, Tanzania, to consider the development of a burn unit there. This institutional partnership provided a unique opportunity to promote sustainable academic exchange and build burn care capacity in the East African region. A Weill Cornell burn surgeon and burn fellow collaborated with the Sekou Toure department of surgery to assess its current burn care capabilities and potential for burn unit development. All aspects of interdisciplinary burn care were reviewed and institutional infrastructure evaluated. Sekou Toure is a 375-bed regional referral center and teaching hospital of Weill Bugando Medical College. In 2010-2011, it admitted 5244 pediatric patients in total; 100 of these patients were burn-injured children (2% of admissions). There was no specific data kept on percentage of body surface burned, degree of burn, length of stay, or complications. No adult, operative, or outpatient burn data were available. There are two operating theaters. Patient's families perform wound care with nursing supervision. Rehabilitation therapists consult as needed. Meals are provided three times daily by a central kitchen. Public health outreach is possible through village-based communication networks. Infrastructure to support the development of a burn care unit exists at Sekou Toure, but needs increased clinical focus, human resource capacity building, and record-keeping to track accurate patient numbers. A multidisciplinary center could improve record-keeping and outcomes, encourage referrals, and facilitate outreach through villages.

  8. National programme for prevention of burn injuries

    Directory of Open Access Journals (Sweden)

    Gupta J


    Full Text Available The estimated annual burn incidence in India is approximately 6-7 million per year. The high incidence is attributed to illiteracy, poverty and low level safety consciousness in the population. The situation becomes further grim due to the absence of organized burn care at primary and secondary health care level. But the silver lining is that 90% of burn injuries are preventable. An initiative at national level is need of the hour to reduce incidence so as to galvanize the available resources for more effective and standardized treatment delivery. The National Programme for Prevention of Burn Injuries is the endeavor in this line. The goal of National programme for prevention of burn injuries (NPPBI would be to ensure prevention and capacity building of infrastructure and manpower at all levels of health care delivery system in order to reduce incidence, provide timely and adequate treatment to burn patients to reduce mortality, complications and provide effective rehabilitation to the survivors. Another objective of the programme will be to establish a central burn registry. The programme will be launched in the current Five Year Plan in Medical colleges and their adjoining district hospitals in few states. Subsequently, in the next five year plan it will be rolled out in all the medical colleges and districts hospitals of the country so that burn care is provided as close to the site of accident as possible and patients need not to travel to big cities for burn care. The programme would essentially have three components i.e. Preventive programme, Burn injury management programme and Burn injury rehabilitation programme.

  9. Classification of mouth movements using 7 T fMRI (United States)

    Bleichner, M. G.; Jansma, J. M.; Salari, E.; Freudenburg, Z. V.; Raemaekers, M.; Ramsey, N. F.


    Objective. A brain-computer interface (BCI) is an interface that uses signals from the brain to control a computer. BCIs will likely become important tools for severely paralyzed patients to restore interaction with the environment. The sensorimotor cortex is a promising target brain region for a BCI due to the detailed topography and minimal functional interference with other important brain processes. Previous studies have shown that attempted movements in paralyzed people generate neural activity that strongly resembles actual movements. Hence decodability for BCI applications can be studied in able-bodied volunteers with actual movements. Approach. In this study we tested whether mouth movements provide adequate signals in the sensorimotor cortex for a BCI. The study was executed using fMRI at 7 T to ensure relevance for BCI with cortical electrodes, as 7 T measurements have been shown to correlate well with electrocortical measurements. Twelve healthy volunteers executed four mouth movements (lip protrusion, tongue movement, teeth clenching, and the production of a larynx activating sound) while in the scanner. Subjects performed a training and a test run. Single trials were classified based on the Pearson correlation values between the activation patterns per trial type in the training run and single trials in the test run in a ‘winner-takes-all’ design. Main results. Single trial mouth movements could be classified with 90% accuracy. The classification was based on an area with a volume of about 0.5 cc, located on the sensorimotor cortex. If voxels were limited to the surface, which is accessible for electrode grids, classification accuracy was still very high (82%). Voxels located on the precentral cortex performed better (87%) than the postcentral cortex (72%). Significance. The high reliability of decoding mouth movements suggests that attempted mouth movements are a promising candidate for BCI in paralyzed people.

    Fraga, Cindy; Velasques, Bruna; Koch, Alexander J; Machado, Marco; Paulucio, Dailson; Ribeiro, Pedro; Pompeu, Fernando Augusto Monteiro Saboia


    Mouth rinsing with a CHO solution has been suggested to improve short (<1 h) endurance performance through central effect. We examined the effects of mouth rinsing with a CHO solution on running time to exhaustion on a treadmill. Six well-trained subjects ran to exhaustion at 85% VO2max , on three separate occasions. Subjects received either an 8% CHO solution or a placebo (PLA) every 15 min to mouth rinse (MR) or a 6% CHO solution to ingest (ING). Treatments were assigned in a randomized, counterbalanced fashion, with the mouth-rinsing treatments double-blinded. Blood samples were taken to assess glucose (Glu) and lactate (Lac), as well as the perceived exertion (RPE). Gas exchange and heart rate (HR) were collected during all trials. Subjects ran longer (P = 0·038) in both the MR (2583 ± 686 s) and ING (2625 ± 804 s) trials, compared to PLA (1935 ± 809 s), covering a greater distance (MR 9685 ± 3511·62 m; ING 9855 ± 4118·62; PLA 7295 ± 3727 m). RER was significantly higher in both ING and MR versus PLA. No difference among trials was observed for other metabolic or cardiovascular variables (VO2 , Lac, Glu, HR), nor for RPE. Endurance capacity, based on time to exhaustion on a treadmill, was improved when either mouth rinsing or ingesting a CHO solution, compared to PLA.

    Seventy-eight burned patients (53 males and 25 females) were classified into 4 groups (mild type: 14 cases, moderate type: 13 cases, severe type: 17 cases and super-severe type: 34 cases) in accordence with criteria established by the Chinese Society for burns. Twenty-two parameters related to platelet, coagulant and anticoagulant factors, fibrinolysis system and hemorrheology were determined at first 24 hours, on third and fifth post-burn days. The results were as follow: Fibrinogen antigen, von Willebrand factor antigen, plasminogen activitor inhibitor activity, thromboxane B2 and hematocrit and whole blood viscosity significantly increased, however antithrombin Ⅲ, protein C antigen, free protein S and 6-keto-prostaglandin F1α markedly decreased compared with normal control at first 24 hours post burn. In addition, fibrinogen antigen, von Willebrand factor antigen, plasminogen activitor inhibitor activity, thromboxane B2 and whole blood viscosity were persistently elevated, however, antithrombin Ⅲ, protein C, free protein S and 6-keto-prostaglandin F1α declined on third and fifth post burn days. These changes resulted in a prethrombotic state, being an important factor in genesis of microthrombosis on burn site and the cause of the deepening and aggravation of burn wound on the third and fifth days in burned patients.

    Jeschke, Marc G; Patsouris, David; Stanojcic, Mile; Abdullahi, Abdikarim; Rehou, Sarah; Pinto, Ruxandra; Chen, Peter; Burnett, Marjorie; Amini-Nik, Saeid


    Over the last decades advancements have improved survival and outcomes of severely burned patients except one population, elderly. The Lethal Dose 50 (LD50) burn size in elderly has remained the same over the past three decades, and so has morbidity and mortality, despite the increased demand for elderly burn care. The objective of this study is to gain insights on why elderly burn patients have had such a poor outcome when compared to adult burn patients. The significance of this project is that to this date, burn care providers recognize the extreme poor outcome of elderly, but the reason remains unclear. In this prospective translational trial, we have determined clinical, metabolic, inflammatory, immune, and skin healing aspects. We found that elderly have a profound increased mortality, more premorbid conditions, and stay at the hospital for longer, p 0.05, but a significant increased incidence of multi organ failure, p response, increased hyperglycemic and hyperlipidemic responses, inversed inflammatory response, immune-compromisation and substantial delay in wound healing predominantly due to alteration in characteristics of progenitor cells, p responses to burns when compared to adults associated with increased morbidity and mortality. This study indicates that these responses are complex and not linear, requiring a multi-modal approach to improve the outcome of severely burned elderly.

    A 5-year retrospective review of 157 pediatric patients admitted to burn center of Kaohsiung Medical University Hospital (Kaohsiung, Taiwan) was undertaken to identify the incidence, mechanism, and agents of pediatric burn. The highest incidence of pediatric burn was in children aged 1-6 years (57.3%), followed by age group 6-14 years (31.8%). Scald burn (75.2%) made up the major cause of this injury and was dominant in each age group compared to non-scald burn. The kitchen/dining area (57.3%) and living room (29.9%) accounted for the most frequent places where pediatric burns occurred. Among the agents of scald burn, hot drink (49.2%) and soup (32.2%) were the two leading causes. There were more pediatric burns reported in colder seasons (38.2% and 33.1% in winter and fall respectively) and during dining time (19.7% in 11 a.m.-1 p.m. and 35.0% in 5 p.m.-8 p.m.). The results of this report may be closely related to special culinary habits (use of chafing-dish and making hot tea) in the south of Taiwan.

  8. Sexual Function Following Burn Injuries: Literature Review. (United States)

    Pandya, Atisha A; Corkill, Helen A; Goutos, Ioannis


    Sexual function is a profound facet of the human personality. Burns due their sudden and devastating nature can have longstanding effects on intimate function by virtue of physical sequelae as well as alterations in body image and perceived desirability. A considerable number of patients encounter problems with intimate function in burns rehabilitation; nevertheless, the topic appears to be poorly addressed in specialist centers worldwide. Review of the literature suggests that a number of parameters can affect the quality of sexual life following burn injuries including age at the time of injury, location, and severity of the burn as well as coping mechanisms employed by the individual survivor. Addressing issues of intimacy relies on awareness, education, and a holistic approach on behalf of the multidisciplinary team members and, to this effect, recommendations are made on managing sexual function concerns in burns rehabilitation.

    The objectives of this study were 1) to describe a case of crusted scabies (CS) in a burned patient, which was primarily undiagnosed and led to a nosocomial outbreak in the burn unit; 2) to analyze and discuss the difficulties in diagnosing and treating this subset of patients with burn injury......; and 3) to design a treatment strategy for future patients. Case analysis and literature review were performed. The index patient had undiagnosed crusted scabies (sive Scabies norvegica) with the ensuing mite hyperinfestation when admitted to the department with minor acute dermal burns. Conservative...... healing and autograft healing were impaired because of the condition. Successful treatment of the burns was only accomplished secondarily to scabicide treatment. An outbreak of scabies among staff members indirectly led to diagnosis. CS is ubiquitous, and diagnosis may be difficult. This is the first...

  10. Modern trends in fluid therapy for burns. (United States)

    Tricklebank, Stephen


    The majority of burn centres use the crystalloid-based Parkland formula to guide fluid therapy, but patients actually receive far more fluid than the formula predicts. Resuscitation with large volumes of crystalloid has numerous adverse consequences, including worsening of burn oedema, conversion of superficial into deep burns, and compartment syndromes. Resuscitation fluids influence the inflammatory response to burns in different ways and it may be possible, therefore to affect this response using the appropriate fluid, at the appropriate time. Starches are effective volume expanders and early use of newer formulations may limit resuscitation requirements and burn oedema by reducing inflammation and capillary leak. Advanced endpoint monitoring may guide clinicians in when to 'turn off' aggressive fluid therapy and therefore avoid the problems of over-resuscitation.

  11. Long hair, smoking, and deep facial burns. (United States)

    Koljonen, Virve


    The purpose of this article is to describe deep facial burn injuries by cigarette lighters in longhaired adults and to report our experience in their treatment. Eight consecutive cigarette lighter burn victims are treated in the Helsinki Burn Center in the year 2006. Seven of the patients were women; their mean age was 50 years. All were under the influence of alcohol at the time of injury. The mean burnt area was 3.5% TBSA. The burnt areas were primarily forehead, cheek, and ipsilateral ear. After a conservative treatment, all the patients underwent an operation, whereby the nonhealing burns were excised and covered with autologous split thickness skin grafts. Postoperative period was uneventful in all the patients. Besides having severe detrimental effects on general health status and wound healing, smoking is the leading cause of residential and total fire deaths worldwide. The patients in this article suffered deep facial burns because of cigarette lighters.

    Bras, Marijana; Loncar, Zoran; Brajković, Lovorka; Gregurek, Rudolf; Micković, Vlatko


    This study examined the relationship between coping strategies, anxiety and depression levels and burn injury characteristics in the early phase of the treatment in burn-injured patients. Seventy patients with severe burns were interviewed within two weeks of their burn trauma. Coping strategies were measured by the coping with burns questionnaire (CBQ). Anxiety and depression levels were assessed with the Beck Depression Inventory and the Beck Anxiety Inventory. There were no statistically significant gender differences in various coping strategies. Avoidance was associated with higher levels of anxiety, depression and hopelessness. The percentage of total body surface area (TBSA) and localization of burns were not associated with coping patterns. Implications for the assessment and management of burn injured patients were discussed.

  14. The Ocular Surface Chemical Burns

    Directory of Open Access Journals (Sweden)

    Medi Eslani


    Full Text Available Ocular chemical burns are common and serious ocular emergencies that require immediate and intensive evaluation and care. The victims of such incidents are usually young, and therefore loss of vision and disfigurement could dramatically affect their lives. The clinical course can be divided into immediate, acute, early, and late reparative phases. The degree of limbal, corneal, and conjunctival involvement at the time of injury is critically associated with prognosis. The treatment starts with simple but vision saving steps and is continued with complicated surgical procedures later in the course of the disease. The goal of treatment is to restore the normal ocular surface anatomy and function. Limbal stem cell transplantation, amniotic membrane transplantation, and ultimately keratoprosthesis may be indicated depending on the patients’ needs.

  15. Threshold age and burn size associated with poor outcomes in the elderly after burn injury. (United States)

    Jeschke, Marc G; Pinto, Ruxandra; Costford, Sheila R; Amini-Nik, Saeid


    Elderly burn care represents a vast challenge. The elderly are one of the most susceptible populations to burn injuries, but also one of the fastest growing demographics, indicating a substantial increase in patient numbers in the near future. Despite the need and importance of elderly burn care, survival of elderly burn patients is poor. Additionally, little is known about the responses of elderly patients after burn. One central question that has not been answered is what age defines an elderly patient. The current study was conducted to determine whether there is a cut-off age for elderly burn patients that is correlated with an increased risk for mortality and to determine the burn size in modern burn care that is associated with increased mortality. To answer these questions, we applied appropriate statistical analyses to the Ross Tilley Burn Centre and the Inflammatory and Host Response to Injury databases. We could not find a clear cut-off age that differentiates or predicts between survival and death. Risk of death increased linearly with increasing age. Additionally, we found that the LD50 decreases from 45% total body surface area (TBSA) to 25% TBSA from the age of 55 years to the age of 70 years, indicating that even small burns lead to poor outcome in the elderly. We therefore concluded that age is not an ideal to predictor of burn outcome, but we strongly suggest that burn care providers be aware that if an elderly patient sustains even a 25% TBSA burn, the risk of mortality is 50% despite the implementation of modern protocolized burn care.

  16. [Quantification of crop residue burned areas based on burning indices using Landsat 8 image]. (United States)

    Ma, Jian-hang; Song, Kai-shar; Wen, Zhi-dan; Shao, Tian-tian; Li, Bo-nan; Qi, Cai


    Crop residue burning leads to atmospheric pollution and is an enormous waste of crop residue resource. Crop residue burning can be monitored timely in large regions as the fire points can be recognized through remotely sensed image via thermal infrared bands. However, the area, the detailed distribution pattern and especially the severity of the burning areas cannot be derived only by the thermal remote sensing approach. The burning index, which was calculated with two or more spectral bands at where the burned and unburned areas have distinct spectral characteristics, is widely used in the forest fire investigation. However its potential application for crop residue burning evaluation has not been explored. With two Landsat 8 images that cover a part of the Songnen Plain, three burning indices, i.e., the normalized burned ratio (NBR), the normalized burned ratio incorporating the thermal band (NBRT), and the burned area index (BAI), were used to classify the crop residue burned and unburned areas. The overall classification accuracies were 91.9%, 92.3%, and 87.8%, respectively. The correlation analysis between the indices and the crop residue coverage indicated that the NBR and NBRT were positively correlated with the crop residue coverage (R2 = 0.73 and 0.64, respectively) with linear regression models, while the BAI was exponentially correlated with the crop residue coverage (R2 = 0.68). The results indicated that the use of burning indices in crop residue burning monitoring could quantify crop residue burning severity and provide valuable data for evaluating atmospheric pollution.

  17. Randomized crossover comparison of the laryngeal mask airway classic with i-gel laryngeal mask airway in the management of difficult airway in post burn neck contracture patients

    Directory of Open Access Journals (Sweden)

    Jeevan Singh


    Full Text Available Purpose: The objective of the study was to compare the performance of i-gel supraglottic airway with cLMA in difficult airway management in post burn neck contracture patients and assess the feasibility of i-gel use for emergency airway management in difficult airway situation with reduced neck movement and limited mouth opening. Methods: Prospective, crossover, randomized controlled trial was performed amongst forty eight post burn neck contracture patients with limited mouth opening and neck movement. i-gel and cLMA were placed in random order in each patient. Primary outcome was overall success rate. Other measurements were time to successful ventilation, airway leak pressure, fiberoptic glottic view, visualization of square wave pattern. Results: Success rate for the i-gel was 91.7% versus 79.2% for the cLMA. i-gel required shorter insertion time (19.3 seconds vs. 23.5 seconds, P=0.000. Airway leak pressure difference was statistically significant (i-gel 21.2 cm H20; cLMA 16.9 cm H 2 0; P=0.00. Fiberoptic view through the i-gel showed there were less epiglottic downfolding and better fiberoptic view of the glottis than cLMA. Overall agreement in insertion outcome for i-gel was 22/24 (91.7% successes and 2/24(8.3% failure and for cLMA, 19/24 (79.16% successes and 5/24 (16.7% failure in the first attempt. Conclusion: The i-gel is cheap, effective airway device which is easier to insert and has better clinical performance in the difficult airway management of the airway in the post burn contracture of the neck. Our study shows that i-gel is feasible for emergency airway management in difficult airway situation with reduced neck movement and limited mouth opening in post burn neck.

  18. Reactive burn models and ignition & growth concept

    Directory of Open Access Journals (Sweden)

    Shaw M.S.


    Full Text Available Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature. This leads to the Ignition & Growth concept, introduced by LeeTarver in 1980, as the basis for reactive burn models. A homo- genized burn rate needs to account for three meso-scale physical effects: (i the density of active hot spots or burn centers; (ii the growth of the burn fronts triggered by the burn centers; (iii a geometric factor that accounts for the overlap of deflagration wavelets from adjacent burn centers. These effects can be combined and the burn model defined by specifying the reaction progress variable λ = g(s as a function of a dimensionless reaction length s(t = rbc/ℓbc, rather than by specifying an explicit burn rate. The length scale ℓbc(Ps = [Nbc(Ps]−1/3 is the average distance between burn centers, where Nbc is the number density of burn centers activated by the lead shock. The reaction length rbc(t = ∫t0 D(P(t′dt′ is the distance the burn front propagates from a single burn center, where D(P is the deflagration speed as a function of the local pressure and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. We have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

  19. [A mouth cavity mucosa membrane illnesses and haemophilia]. (United States)

    Gvazava, T; Abashidze, M


    To reveal the frequency of parodontitis, parodontosis and gingivitis among patients with haemophilia the structure of inflammatory diseases of mouth cavity mucosa was investigated. 224 patients (aged 2-64 years old) with the various forms of haemophilia were examined. The investigation showed that the occurrence of parodontitis, parodontosis and gingivitis in patients with haemophilia was significantly higher than in control group. In case of haemophilia relative and attributic risk of inflammatory diseases of mouth cavity mucosa rises: parodontitis (RR=2,15; 95%CI: 1,75-2,63; AR=0,48; 95%CI: 0,39-1,04); parodontosis (RR=1,41; 95%CI: 1,251,60; AR=0,26; 95%CI: 0,17-0,85) and gingivitis (RR=2,26; 95%CI: 1,86-2,74; AR=0,53; 95%CI: 0,44-0,96), but they do not correlate with the severity of illness.

  1. Dermoid Cyst of the Floor of the Mouth

    Directory of Open Access Journals (Sweden)

    Sergio M. Lima


    Full Text Available Dermoid cysts of the floor of the mouth are rare lesions thought to be caused by entrapment of germinal epithelium during the closure of the mandibular and hyoid branchial arches. They usually present as a nonpainful swelling. This type of lesion occurs more frequently in patients between 15 and 35 years, but can be seen in all age ranges. Histologically, all dermoids are lined by epidermis. The contents of the cyst lining determine the histological categories of the cyst: epidermoid, if epidermis is lining the cyst; dermoid, if skin annexes exist; or teratoid, if there are tissues derivated from the three germinal layers. Anatomical classification is useful for surgical approach choice, intra- or extraorally. This report presents a case of a dermoid cyst of the floor of the mouth in a 12-year-old patient, and a review of all steps necessary for its diagnosis and treatment was made.

  2. Imaging the floor of the mouth and the sublingual space. (United States)

    La'porte, Sarah J; Juttla, Jaspal K; Lingam, Ravi K


    A wide range of pathologic processes may involve the floor of the mouth, the part of the oral cavity that is located beneath the tongue. They include lesions that arise uniquely in this location (eg, ranula, submandibular duct obstruction) as well as various malignancies, inflammatory processes, and vascular abnormalities that may also occur elsewhere in the head and neck. Some lesions that arise in superficial tissues such as the mucosa may be easily diagnosed at physical examination. However, computed tomography, magnetic resonance imaging, or ultrasonography may be necessary for a reliable assessment of lesion extension to deeper structures. In such cases, knowledge of the complex muscular, vascular, glandular, ductal, and neural anatomy of the region is important for accurate diagnosis and treatment planning. Familiarity with the radiologic imaging appearances of the floor of the mouth and recognition of anatomic landmarks such as the mylohyoid and hyoglossus muscles are especially useful for localizing disease within this region.

  3. Customer Protest: Exit, Voice or Negative Word of Mouth

    Directory of Open Access Journals (Sweden)

    Solvang, B. K.


    Full Text Available Of the three forms of protest the propensity of word of mouth (WOM seems to be the most common, and the most exclusive form of protest seems to be exit. The propensity for voice lies in between. The costs linked to voice influence the propensity for WOM. The customers seem to do an evaluation between the three forms of protest, yet the rational picture of the customers should be moderated.Leaders should improve their treatment of the customers making complaints. The more they can treat customer complaints in an orderly and nice way the less informal negative word of mouth activity they will experience and they will reduce the exit propensity and lead the customers to the complain organisation. They should also ensure that their customers feel they get equal treatment by the staff.

  4. Restricted mouth opening and trismus in oral oncology. (United States)

    Satheeshkumar, P S; Mohan, Minu P; Jacob, Jayan


    Restricted mouth opening (RMO) and trismus are terms commonly used in oral oncology in instances where there is difficulty in mouth opening. The term trismus in oral oncology is mainly used to indicate the radiation-induced fibrosis of the muscles of mastication. The treatment given for RMO as reported in the literature is given for muscular dysfunction trismus, whereas RMO in oral oncology can occur owing to various reasons other than muscular dysfunction. RMO occurs in various conditions of the oral cavity; in posterior pharyngeal infection, where it is termed reflectory trismus; in oral submucous fibrosis; in oral mucosal disorders; in the use of certain drugs; and in minor dental procedures of the posterior oral cavity. The usage of the term trismus in all RMO cases would complicate the treatment; thus, the word should not be used in all RMO cases.

    Modern burn care techniques have reduced the risk of infection of the acute burn wound, resulting in more rapid healing and a lower incidence of graft loss. Secondary breakdown may still occur. The loss of epithelium in association with multifocal superficial abscesses and ulceration has been termed burns impetigo. This may result in considerable morbidity and require prolonged treatment. The events preceding development, the impact on the patient, and the ideal treatment appear unclear and poorly reported. In 5 years, between 2006 and 2011, 406 pediatric burns were treated with skin grafts, with 7% developing burns impetigo. Time to resolution ranged from 5 to 241 days: the mean time to complete healing was greatest with conservative management (96 days), followed by antibacterial dressings (37 days), oral antibiotics (36 days), topical steroids (16 days), and oral antibiotics in combination with topical steroids (13.5 days). Burns impetigo resulted in significant morbidity, requiring multiple visits to the treatment center and prolonged symptoms. Delay in diagnosis and treatment resulted in worse outcomes. Prompt consideration of burns impetigo should occur when postgraft patients present with suggestive clinical signs and treatment with oral antibiotics plus topical steroids should be considered.

  6. Burning characteristics of microcellular combustible objects

    Directory of Open Access Journals (Sweden)

    Wei-tao Yang


    Full Text Available Microcellular combustible objects for application of combustible case, caseless ammunition or combustible detonator-holding tubes are fabricated through one-step foaming process, in which supercritical CO2 is used as foaming agent. The formulations consist of inert polymer binder and ultra fine RDX. For the inner porous structures of microcellular combustible objects, the cell sizes present a unimodal or bimodal distribution by adjusting the foaming conditions. Closed bomb test is to investigate the influence of both porous structure style and RDX content on burning behavior. The sample with bimodal distribution of cell sizes burns faster than that with unimodal distribution, and the concentration of RDX can influence the burning characteristics in a positive manner. In addition, the translation of laminar burning to convective burning is determined by burning rate versus pressure curves of samples at two different loading densities, and the resulting transition pressure is 30 MPa. Moreover, the samples with bigger sample size present higher burning rate, resulting in providing deeper convective depth. Dynamic vivacity of samples is also studied. The results show that the vivacity increases with RDX content and varies with inner structure.

  7. Infections in critically ill burn patients. (United States)

    Hidalgo, F; Mas, D; Rubio, M; Garcia-Hierro, P


    Severe burn patients are one subset of critically patients in which the burn injury increases the risk of infection, systemic inflammatory response and sepsis. The infections are usually related to devices and to the burn wound. Most infections, as in other critically ill patients, are preceded by colonization of the digestive tract and the preventative measures include selective digestive decontamination and hygienic measures. Early excision of deep burn wound and appropriate use of topical antimicrobials and dressings are considered of paramount importance in the treatment of burns. Severe burn patients usually have some level of systemic inflammation. The difficulty to differentiate inflammation from sepsis is relevant since therapy differs between patients with and those without sepsis. The delay in prescribing antimicrobials increases morbidity and mortality. Moreover, the widespread use of antibiotics for all such patients is likely to increase antibiotic resistance, and costs. Unfortunately the clinical usefulness of biomarkers for differential diagnosis between inflammation and sepsis has not been yet properly evaluated. Severe burn injury induces physiological response that significantly alters drug pharmacokinetics and pharmacodynamics. These alterations impact antimicrobials distribution and excretion. Nevertheless the current available literature shows that there is a paucity of information to support routine dose recommendations.

  8. Ultrasound assessed thickness of burn scars in association with laser Doppler imaging determined depth of burns in paediatric patients. (United States)

    Wang, Xue-Qing; Mill, Julie; Kravchuk, Olena; Kimble, Roy M


    This study describes the ultrasound assessment of burn scars in paediatric patients and the association of these scar thickness with laser Doppler imaging (LDI) determined burn depth. A total of 60 ultrasound scar assessments were conducted on 33 scars from 21 paediatric burn patients at 3, 6 and 9 months after-burn. The mean of peak scar thickness was 0.39±0.032 cm, with the thickest at 6 months (0.40±0.036 cm). There were 17 scald burn scars (0.34±0.045 cm), 4 contact burn scars (0.61±0.092 cm), and 10 flame burn scars (0.42±0.058 cm). Each group of scars followed normal distributions. Twenty-three scars had original burns successfully scanned by LDI and various depths of burns were presented by different colours according to blood perfusion units (PU), with dark blue burns, with the thinnest scars for green coloured burns and the thickest for dark blue coloured burns. Within light blue burns, grafted burns healed with significantly thinner scars than non-grafted burns. This study indicates that LDI can be used for predicting the risk of hypertrophic scarring and for guiding burn care. To our knowledge, this is the first study to correlate the thickness of burns scars by ultrasound scan with burn depth determined by LDI.

    Reports of injuries caused by kickboxing, one of the contact sports that potentially causes a large number of injuries, are relatively rare. Wearing a mouthguard is obligatory in kickboxing, but the association between maxillofacial injuries and the quality of mouthguards has not been described thus far. In this article, we present a case of mandibular fracture in a 25-year-old male, who was injured during kickboxing despite wearing a mouth formed mouthguard.

    Full Text Available This study was done to mask the bitter taste of ondansetron HCl using complexing agent, a polacrilex resin: Tulsion 335 and subsequently forming mouth dissolving tablet using superdisintegrants: Croscarmellose sodium and sodium starch glycollate. A preliminary screening was done. Batch process, a most preferential method for drug loading with ion exchange resins was selected. The process was optimized for drug: resin ratio to get maximum drug loading. A ratio of drug: resin at 1:3 was selected. Taste evaluation was carried out by selecting volunteers. Drug resin complex (DRC was evaluated for drug release. The resultant DRC was formulated by direct compression into mouth dissolving tablet using microcrystalline cellulose PH 102, as diluent and croscarmalose sodium and sodium starch glycolate as superdisintegrants and aspartame was used as sweetening agent to enhance palatability. Thirteen formulations were developed by using superdisintegrants: croscarmellose sodium and sodium starch glycolate. Concentration of superdisintegrants ranged from 0.75-9.24 %. The formulated tablet had satisfactory disintegration time and dissolution profile. Optimization was carried out using central composite design. The disintegration and dissolution times were tallied with marketed ondansetron HCl tablets. From the results, it was deduced that the most effective concentration for desired disintegration was of croscarmellose sodium and sodium starch glycollate respectively at concentration above 5%. Therefore, it can be concluded that the intensely bitter taste of ondansetron HCl can be masked by using tulsion 335 and mouth dissolving ondansetron HCl can be successfully prepared by adding aforementioned superdisintegrants. This sort of mouth dissolving ondansetron HCl can be used in controlling vomiting in paediatric and geriatric patients and also for pregnancy induced vomiting.

  11. Burn care professionals' attitudes and practices regarding discussions of sexuality and intimacy with adult burn survivors. (United States)

    Rimmer, Ruth Brubaker; Rutter, Cindy E; Lessard, Collette R; Pressman, Melissa Singer; Jost, Janet Cusick; Bosch, James; Foster, Kevin N; Caruso, Daniel M


    Burn injury survival means coping with more than just the physical changes and disabilities often encountered after burn injury. Overall quality of life is important, and issues such as sexuality and intimacy are significant facets of quality of life. A literature review revealed limited research regarding current burn center practices related to sexuality and intimacy concerns of burn survivors and their partners. A 28-item survey, designed by seasoned burn care professionals and survivors, was distributed to burn care practitioners attending general sessions at several burn conferences in the United States. Seventy-one (86%) of the invited respondents completed the survey, with nursing representing the majority (63%). Mean tenure working in burn care was 10 years. Mean age of respondents was 40.5 years, with 75% being female and 25% male. Nearly half (47%) reported that specific staff was not designated to discuss sexuality and intimacy with survivors in their center. Sixty-two percent reported that special training regarding sexuality and intimacy was not available at their burn center. Only 14% of respondents indicated that they were "very comfortable" initiating conversation regarding these topics. Fifty-five percent said they were only likely to discuss sexuality and intimacy if the patient/partner initiated the discussion; however, 95% agreed that the patient should not have this responsibility. Although results represent findings from only 37 burn centers, the issues of sexuality and intimacy are not being effectively addressed in the participating centers. Designated staff to provide education is lacking, and there is limited comfort on the part of health care providers in initiating such conversations. These factors seem to often prevent burn care professionals from adequately addressing burn survivor's sexuality and intimacy needs and establish the need for further development of training and educational materials specific to sexuality, intimacy, and

  12. Burning of droplets and particles of explosives

    Energy Technology Data Exchange (ETDEWEB)

    Kondrikov, B.N. [Mendeleev University of Chemical Technology, Moscow (Russian Federation)


    Small droplets of organic diazides investigated by C.K. Law and coworkers burn in hot gas at 1 atm with rates inversely proportional to the droplet diameter presumably owing to leading chemical reaction proceeds in gas phase. These burning rates are obviously much lower than those obtained by extrapolation of the results measured for the some substances in glass tubes (at pressure of about 10{sup -2}-10{sup -1} atm, and temperature 0-100 deg C) on the burning conditions of the droplets. Kinetic constants estimated using Zel`dovich equation for the burning rate in gas phase and Semenov relation for delay time of the droplets micro-explosion in liquid phase are about the same: E {approx_equal} 0.17 MJ/mol, log{sub 10}k{sub o} {approx_equal} 15(S{sup -1}). In both of the cases the leading chemical reaction is supposed to be of the first order. Landau instability is assumed to be reflected in distortion of the droplets at burning but, as opposed to the liquids pools or columns burning, it is not followed by the burning rate augmentation or (as it is observed sometimes) by the combustion extinguishment. Simple dependence of burning rate of droplets of diazides of the row of normal alkanes on their enthalpy of formation is obtained. Burning rate of ball-shaped particles of polyvinyl-nitrate estimated by A. Merzhanov and collaborators is about the same as measured by the data E.I. Maximov, the member of the same team, for PVN strands, at extrapolation of his results on the suggested preheating temperature of the particle. Probably it is a result of the leading chemical reaction proceeding in condensed phase. (author) 10 refs.

  13. Childhood burns in south eastern Nigeria

    Okoro Philemon


    Full Text Available Background: Burns injuries are recognized as a major health problem worldwide. In children and, particularly, in our environment where poverty, ignorance and disease are still high, they constitute significant morbidity and mortality. Previous studies on this topic in parts of Nigeria either lumped adults and children together or were retrospective. We, therefore, prospectively studied the current trends in burns in children. Patients and Methods: This prospective study of burns spanned over a period of 18 months (June 2006-December 2007 at the Paediatric Surgery Units of the Imo State University Teaching Hospital, Orlu, and the Federal Medical Centre, Owerri, Imo State. Data were collected and analysed for age, sex, cause/type of burn, place of burn, presence or absence of adult/s, initial prehospital intervention, interval between injury and presentation, surface area and depth of burn and treatment and outcome. Results: Fifty-three patients were studied, 31 (58.4% were male and 22 (41.6% were female (M:F = 1.4:1. Patients mostly affected were aged 2 years and below. The most common cause of burns was hot water in 31 (58.5% patients. The vast majority of these injuries happened in a domestic environment (92.5% and in the presence of competent adult/s (88.7%. Outcome of treatment was good: there were two (3.8% deaths and 46 (86% patients had complete recovery. Conclusion: Burns is still a major health problem among children in south eastern Nigeria. Fortunately, outcome of appropriate treatment is good. However, we think that poor safety consciousness among parents is a major predisposing factor. Public enlightenment on measures to ensure safe home environment may be necessary to avoid or limit childhood burns.

  14. The Application of Erosive Burning to Propellant Charge Interior Ballistics

    Institute of Scientific and Technical Information of China (English)

    ZHANG Hong-lin


    Erosive burning is a common burning phenomenon of the gunpowder with inner holes. The actual combustion law of the gunpowder with inner holes can be changed by erosive burning. Pressure difference between the inner and the outer of hole caused by loading density variation of the propellant charge makes erosive burning occur at inner holes during in-bore burning. The effect of erosive burning on burning speed of the propellant is studied by using the effects of flow rate, heat transfer and erosion of the combustion gas in inner holes on burning rate. The mathematic model of erosive burning of the propellant is established. The effects of the factors such as loading density, inner hole size and grain length on erosive burning and interior ballistic performance are analyzed .The method to improve the bore pressure for small charge mass and small firing range by erosive burning is proposed.

    Foot-and-mouth disease is a highly infectious vesicular disease of cloven-hoofed animals caused by foot-and-mouth disease virus. It spreads by direct contact between animals, by animal products (milk, meat and semen), by mechanical transfer on people or fomites and by the airborne route - with the relative importance of each mechanism depending on the particular outbreak characteristics. Over the years a number of workers have developed or adapted atmospheric dispersion models to assess the risk of foot-and-mouth disease virus spread through the air. Six of these models were compared at a workshop hosted by the Institute for Animal Health/Met Office during 2008. A number of key issues emerged from the workshop and subsequent modelling work: (1) in general all of the models predicted similar directions for 'at risk' livestock with much of the remaining differences strongly related to differences in the meteorological data used; (2) determination of an accurate sequence of events is highly important, especially if the meteorological conditions vary substantially during the virus emission period; and (3) differences in assumptions made about virus release, environmental fate, and subsequent infection can substantially modify the size and location of the downwind risk area. Close relationships have now been established between participants, which in the event of an outbreak of disease could be readily activated to supply advice or modelling support.

  16. Flood control and shrinkage in the Haihe River Mouth

    Institute of Scientific and Technical Information of China (English)

    胡世雄; 王兆印; 李行伟


    Because of overusing water resources in the upper and middle reaches of the Haihe Basin, less and less water flows to the river mouth. The Haihe River flow is cut off in most time of the seasons, sediment deposited in the river mouth channel is rarely scoured away, and many of the river mouth channels have been shrinking quickly. The discharge capacity of the channel is consequently reduced greatly, which results in more and more serious flood hazard. Many tide gates have been built for storing fresh water and preventing the salty and turbid water. The channel downstream of the gate is silting up and people have to dredge the channel every year before the flood season. This paper studies the laws of the siltation and strategies controlling channel shrinkage. The strategies are digger dredging, trailer dredging, scouring with pumping water or storing tidal water, building double guiding dikes and building a new gate. Comparison of various strategies is performed, suggesting the most effective strategy con

    The present investigation deals with development of mouth disintegrating tablets of rizatriptan benzoate to produce the intended benefits. Mouth disintegrating tablets of rizatriptan benzoate were prepared using superdisintegrants crospovidone, carboxymethylcellulose calcium, Indion 414 and Indion 234 using the direct compression method. The tablets prepared were evaluated for thickness, uniformity of weight, content uniformity, hardness, friability, wetting time, in vitro and in vivo disintegration time, mouth feel, in vitro drug release and assay by high performance liquid chromatography. The tablets disintegrated in vitro and in vivo within 4 to 7 s and 6 to 19 s, respectively. Almost 90% of drug was released from all formulations within 20 min. The drug release from the formulations followed first order kinetics. Stability studies of the tablets at 40+/-2 degrees /75%+/-5% RH for 1 mo showed non significant drug loss. The formulation containing combination of crospovidone and Indion 234 was found to give the best results. Apart from fulfilling all official and other specifications, the tablets exhibited higher rate of release.

  19. Guidelines proposal for clinical recognition of mouth breathing children

    Directory of Open Access Journals (Sweden)

    Maria Christina Thomé Pacheco


    Full Text Available INTRODUCTION: Mouth breathing (MB is an etiological factor for sleep-disordered breathing (SDB during childhood. The habit of breathing through the mouth may be perpetuated even after airway clearance. Both habit and obstruction may cause facial muscle imbalance and craniofacial changes.OBJECTIVE: The aim of this paper is to propose and test guidelines for clinical recognition of MB and some predisposing factors for SDB in children.METHODS: Semi-structured interviews were conducted with 110 orthodontists regarding their procedures for clinical evaluation of MB and their knowledge about SDB during childhood. Thereafter, based on their answers, guidelines were developed and tested in 687 children aged between 6 and 12 years old and attending elementary schools.RESULTS: There was no standardization for clinical recognition of MB among orthodontists. The most common procedures performed were inefficient to recognize differences between MB by habit or obstruction.CONCLUSIONS: The guidelines proposed herein facilitate clinical recognition of MB, help clinicians to differentiate between habit and obstruction, suggest the most appropriate treatment for each case, and avoid maintenance of mouth breathing patterns during adulthood.

  20. C-2-C market relations and word of mouth

    Directory of Open Access Journals (Sweden)

    Grubor Aleksandar


    Full Text Available Most market research focuses on business-to-business and business- to-consumer interactions to explain the structure and dynamics of the market. Meanwhile, negligible effort has been invested in researching consumer-to-consumer interaction and its impact on companies’ behaviour and purchase decision-making, which determines business performance. The greatest challenge for marketers at the beginning of the 21st century is this third relationship dimension, consumer-to-consumer interaction: how consumers influence each other’s attitudes, expectations, perceptions, preferences, satisfaction, loyalty, and purchasing decisions, and, importantly, the possibility of incorporating consumers into businesses’ marketing programmes. Despite the existence of a multitude of media and different forms of communication between businesses and the market, such as newspapers, periodicals, billboards, television etc., a considerable portion of information is communicated to consumers informally, mostly in the form of word-of-mouth. The information received by consumers through this communication form - from family and similar individuals -is very often accepted as more reliable and certain than information transmitted through formal communication channels. What is often neglected when studying the phenomenon of word-of-mouth communication is the fact that its efficiency and effect also depend on the type and character of the interaction between the consumers themselves. This paper aims to investigate the extent to which the nature of customer to-customer (C2C interaction influences the effect of word-of-mouth communication.

  1. Combined glucose ingestion and mouth rinsing improves sprint cycling performance. (United States)

    Chong, Edwin; Guelfi, Kym J; Fournier, Paul A


    This study investigated whether combined ingestion and mouth rinsing with a carbohydrate solution could improve maximal sprint cycling performance. Twelve competitive male cyclists ingested 100 ml of one of the following solutions 20 min before exercise in a randomized double-blinded counterbalanced order (a) 10% glucose solution, (b) 0.05% aspartame solution, (c) 9.0% maltodextrin solution, or (d) water as a control. Fifteen min after ingestion, repeated mouth rinsing was carried out with 11 × 15 ml bolus doses of the same solution at 30-s intervals. Each participant then performed a 45-s maximal sprint effort on a cycle ergometer. Peak power output was significantly higher in response to the glucose trial (1188 ± 166 W) compared with the water (1036 ± 177 W), aspartame (1088 ± 128 W) and maltodextrin (1024 ± 202 W) trials by 14.7 ± 10.6, 9.2 ± 4.6 and 16.0 ± 6.0% respectively (p sprint was significantly higher in the glucose trial compared with maltodextrin (p sprinting did not differ significantly between treatments (p > .05). These findings suggest that combining the ingestion of glucose with glucose mouth rinsing improves maximal sprint performance. This ergogenic effect is unlikely to be related to changes in blood glucose, sweetness, or energy sensing mechanisms in the gastrointestinal tract.

    Treharne, L J; Kay, A R


    The initial management of burns, in common with all trauma, follows the ABCDE approach. The outline management plan detailed above assumes the availability of certain medical supplies but even simple measures are invaluable in burn care if they are all that are available. The most basic supplies required to resuscitate a casualty are oral salt and water in appropriate volumes. Similarly it should be possible in field conditions to monitor vital signs and urine output, dress the burns with clingfilm or plastic bags and wrap the casualty in absorbent materials.

  4. Sediment availability on burned hillslopes (United States)

    Nyman, Petter; Sheridan, Gary J.; Moody, John A.; Smith, Hugh G.; Noske, Philip J.; Lane, Patrick N. J.


    describes the inherent resistance of soil to erosion. Hillslope erosion models typically consider erodibility to be constant with depth. This may not be the case after wildfire because erodibility is partly determined by the availability of noncohesive soil and ash at the surface. This study quantifies erodibility of burned soils using methods that explicitly capture variations in soil properties with depth. Flume experiments on intact cores from three sites in western United States showed that erodibility of fire-affected soil was highest at the soil surface and declined exponentially within the top 20 mm of the soil profile, with root density and soil depth accounting for 62% of the variation. Variation in erodibility with depth resulted in transient sediment flux during erosion experiments on bounded field plots. Material that contributed to transient flux was conceptualized as a layer of noncohesive material of variable depth (dnc). This depth was related to shear strength measurements and sampled spatially to obtain the probability distribution of noncohesive material as a function of depth below the surface. After wildfire in southeast Australia, the initial dnc ranged from 7.5 to 9.1 mm, which equated to 97-117 Mg ha-1 of noncohesive material. The depth decreased exponentially with time since wildfire to 0.4 mm (or < 5 Mg ha-1) after 3 years of recovery. The results are organized into a framework for modeling fire effects on erodibility as a function of the production and depletion of the noncohesive layer overlying a cohesive layer.

  5. The ALMR actinide burning system

    Energy Technology Data Exchange (ETDEWEB)

    Quinn, J.E. (General Electric Co., San Jose, CA (United States))


    The advanced liquid-metal reactor (ALMR) actinide burning system is being developed under the sponsorship of the US Department of Energy to bring its unique capabilities to fruition for deployment in the early 21st century. The system consists of four major parts: the reactor plant, the metal fuel and its recycle, the processing of light water reactor (LWR) spent fuel to extract the actinides, and the development of a residual waste package. This paper addresses the status and outlook for each of these four major elements. The ALMR is being developed by an industrial group under the leadership of General Electric (GE) in a cost-sharing arrangement with the US Department of Energy. This effort is nearing completion of the advanced conceptual design phase and will enter the preliminary design phase in 1994. The innovative modular reactor design stresses simplicity, economics, reliability, and availability. The design has evolved from GE's PRISM design initiative and has progressed to the final stages of a prelicensing review by the US Nuclear Regulatory Commission (NRC); a safety evaluation report is expected by the end of 1993. All the major issues identified during this review process have been technically resolved. The next design phases will focus on implementation of the basic safety philosophy of passive shutdown to a safe, stable condition, even without scram, and passive decay heat removal. Economic projections to date show that it will be competitive with non- nuclear and advanced LWR nuclear alternatives.

  6. TIGER Burned Brightly in JAMIC (United States)

    Olson, Sandra L.; Kashiwagi, Takashi


    The Transition From Ignition to Flame Growth Under External Radiation in 3D (TIGER- 3D) experiment, which is slated to fly aboard the International Space Station, conducted a series of highly successful tests in collaboration with the University of Hokkaido using Japan's 10-sec JAMIC drop tower. The tests were conducted to test engineering versions of advanced flight diagnostics such as an infrared camera for detailed surface temperature measurements and an infrared spectroscopic array for gas-phase species concentrations and temperatures based on detailed spectral emissions in the near infrared. Shown in the top figure is a visible light image and in the bottom figure is an infrared image at 3.8 mm obtained during the microgravity tests. The images show flames burning across cellulose samples against a slow wind of a few centimeters per second (wind is from right to left). These flow velocities are typical of spacecraft ventilation systems that provide fresh air for the astronauts. The samples are ignited across the center with a hot wire, and the flame is allowed to spread upwind and/or downwind. As these images show, the flames prefer to spread upwind, into the fresh air, which is the exact opposite of flames on Earth, which spread much faster downwind, or with the airflow, as in forest fires.

  7. Characteristics of burn deaths from 2003 to 2009 in a burn center: A retrospective study

    Full Text Available Mortality remains one of the most important end-point quality control parameters to evaluate a burn care system. We retrospectively reviewed the characteristics and multiple organ dysfunction syndrome (MODS patterns of burn deaths in our center from January 2003 to December 2009. The mortality rate during this time period was 2.3%. Fifty-six patients died, including 49 males and 7 females. The mean survival time was 28.45 ± 24.60 days. The burn percentage was (76.70 ± 26.86 % total burn surface area (TBSA, with (27.74 ± 24.95 % deep-partial thickness burns and (46.88 ± 33.84 % full-thickness burns. Inhalation injury was diagnosed in 36 (64.29% patients. Patients who had undergone an operation, particularly in the first week post-burn, had a significantly longer survival time. An average of 5.50 ± 1.35 malfunctioning organs per patient and a mean sequential organ failure assessment (SOFA score of 13.91 ± 3.65 were observed. The most frequently malfunctioning organs were involved in the respiratory, hematologic, circulatory, and central nervous systems. Most of the organ damage occurred during the first week post-burn, followed by 4 weeks later, with relatively less organ damage observed in the third week. Among patients with a TBSA over 50%, non-survivors had larger burn sizes (particularly larger full-thickness burns and a higher incidence of inhalation injury compared with survivors; non-survivors were also more likely to have microorganism-positive blood and sputum cultures. In conclusion, burn deaths are related to a higher burn percentage, inhalation injury, MODS, and infection. Early operation may help improve survival duration.

  8. On burning a lump of coal (United States)

    Alonso-Serrano, Ana; Visser, Matt


    Burning something, (e.g. the proverbial lump of coal, or an encyclopaedia for that matter), in a blackbody furnace leads to an approximately Planck emission spectrum with an average entropy/information transfer of approximately 3.9 ± 2.5 bits per emitted photon. This quantitative and qualitative result depends only on the underlying unitarity of the quantum physics of burning, combined with the statistical mechanics of blackbody radiation. The fact that the utterly standard and unitarity preserving process of burning something (in fact, burning anything) nevertheless has an associated entropy/information budget, and the quantitative size of that entropy/information budget, is a severely under-appreciated feature of standard quantum statistical physics.

  10. Radioactivity released from burning gas lantern mantles. (United States)

    Luetzelschwab, J W; Googins, S W


    Gas lantern mantles contain thorium to produce incandescence when lantern fuel is burned on the mantle. Although only thorium is initially present on the mantle, the thorium daughters build up, some over a period of weeks and some over a period of years, and significant quantities of these daughters are present when the mantle is used. Some of these daughters are released when the lantern fuel is burned on the mantle. The amounts of radioactivity released during burning is studied by measuring the gamma radiation emitted by the daughters. Results of this study show that some of the radium (224Ra and 228Ra) and more than half the 212Pb and 212Bi is released during the first hour of a burn. The actual amounts release depend on the age of the mantle.

    Furfaro, James A.


    A 6-segment subscale motor was developed to generate a range of internal environments from which multiple propellants could be characterized for erosive burning. The motor test bed was designed to provide a high Mach number, high mass flux environment. Propellant regression rates were monitored for each segment utilizing ultrasonic measurement techniques. These data were obtained for three propellants RSRM, ETM- 03, and Castor@ IVA, which span two propellant types, PBAN (polybutadiene acrylonitrile) and HTPB (hydroxyl terminated polybutadiene). The characterization of these propellants indicates a remarkably similar erosive burning response to the induced flow environment. Propellant burnrates for each type had a conventional response with respect to pressure up to a bulk flow velocity threshold. Each propellant, however, had a unique threshold at which it would experience an increase in observed propellant burn rate. Above the observed threshold each propellant again demonstrated a similar enhanced burn rate response corresponding to the local flow environment.

  14. Clay Improvement with Burned Olive Waste Ash

    Directory of Open Access Journals (Sweden)

    Utkan Mutman


    Full Text Available Olive oil is concentrated in the Mediterranean basin countries. Since the olive oil industries are incriminated for a high quantity of pollution, it has become imperative to solve this problem by developing optimized systems for the treatment of olive oil wastes. This study proposes a solution to the problem. Burned olive waste ash is evaluated for using it as clay stabilizer. In a laboratory, bentonite clay is used to improve olive waste ash. Before the laboratory, the olive waste is burned at 550°C in the high temperature oven. The burned olive waste ash was added to bentonite clay with increasing 1% by weight from 1% to 10%. The study consisted of the following tests on samples treated with burned olive waste ash: Atterberg Limits, Standard Proctor Density, and Unconfined Compressive Strength Tests. The test results show promise for this material to be used as stabilizer and to solve many of the problems associated with its accumulation.

  16. Mouth-opening increases upper-airway collapsibility without changing resistance during midazolam sedation. (United States)

    Ayuse, T; Inazawa, T; Kurata, S; Okayasu, I; Sakamoto, E; Oi, K; Schneider, H; Schwartz, A R


    Sedative doses of anesthetic agents affect upper-airway function. Oral-maxillofacial surgery is frequently performed on sedated patients whose mouths must be as open as possible if the procedures are to be accomplished successfully. We examined upper-airway pressure-flow relationships in closed mouths, mouths opened moderately, and mouths opened maximally to test the hypothesis that mouth-opening compromises upper-airway patency during midazolam sedation. From these relationships, upper-airway critical pressure (Pcrit) and upstream resistance (Rua) were derived. Maximal mouth-opening increased Pcrit to -3.6 +/- 2.9 cm H2O compared with -8.7 +/- 2.8 (p = 0.002) for closed mouths and -7.2 +/- 4.1 (p = 0.038) for mouths opened moderately. In contrast, Rua was similar in all three conditions (18.4 +/- 6.6 vs. 17.7 +/- 7.6 vs. 21.5 +/- 11.6 cm H2O/L/sec). Moreover, maximum mouth-opening produced an inspiratory airflow limitation at atmosphere that was eliminated when nasal pressure was adjusted to 4.3 +/- 2.7 cm H2O. We conclude that maximal mouth-opening increases upper-airway collapsibility, which contributes to upper-airway obstruction at atmosphere during midazolam sedation.

  18. Epidemiology and screening of intentional burns in children in a Dutch burn centre. (United States)

    Bousema, Sara; Stas, Helene G; van de Merwe, Marjolijn H; Oen, Irma M M H; Baartmans, Martin G A; van Baar, Margriet E


    International estimates of the incidence of non-accidental burns (NAB) in children admitted to burn centres vary from 1% to 25%. Hardly any data about Dutch figures exist. The aim of this study was to evaluate the incidence, treatment and outcome of burns due to suspected child abuse in paediatric burns. We described the process of care and outcome, including the accuracy of the SPUTOVAMO screening tool and examined child, burn and treatment characteristics related to suspicions of child abuse or neglect. A retrospective study was conducted in children aged 0-17 years with a primary admission after burn injuries to the burn centre Rotterdam in the period 2009-2013. Data on patient, injury and treatment characteristics were collected, using the Dutch Burn Repository R3. In addition, medical records were reviewed. In 498 paediatric admissions, suspected child abuse or neglect was present in 43 children (9%). 442 screening questionnaires (89%) were completed. In 52 out of 442 questionnaires (12%) the completed SPUTOVAMO had one or more positive signs. Significant independent predictors for suspected child abuse were burns in the genital area or buttocks (OR=3.29; CI: 143-7.55) and a low socio-economic status (OR=2.52; 95%CI: 1.30-4.90). The incidence of suspected child abuse indicating generation of additional support in our population is comparable to studies with a similar design in other countries.

  19. [Treatment of pain in children burns]. (United States)

    Latarjet, J; Pommier, C; Robert, A; Comparin, J P; Foyatier, J L


    Burn injury is considered by children as one of the most painful traumas (just after bone factures). Burn pain in children can and must be controlled as well as for adult patients, with almost identical techniques. Continuous pain from injury and intermittent pain caused by therapeutic procedures must be evaluated and treated separately. Due to very high levels of nociception, satisfactory management of procedural pain requires the use of opioid therapy. Non pharmacological methods are meaningless if pharmacological treatment is not optimal.

  2. Disseminated intravascular coagulation in burn injury. (United States)

    Lippi, Giuseppe; Ippolito, Luigi; Cervellin, Gianfranco


    Disseminated intravascular coagulation (DIC) is a complex and multifaceted disorder characterized by the activation of coagulation and fibrinolytic pathways, consumption of coagulation factors, and depletion of coagulation regulatory proteins. The introduction into the circulation of cellular debris characterized by strong thromboplastic activity due to tissue factor exposition or release (in or from burned tissues), which can thereby activate extrinsic pathway of coagulation system and trigger massive thrombin generation when present in sufficient concentration, represents the most plausible biological explanation to support the development of intravascular coagulation in patients with burn injury. Severe burns left untreated might also lead to an immunological and inflammatory response (activation of the complement cascade), which can amplify fibrinolysis and blood clotting. Overall, the real prevalence of DIC in patients with burns is as yet unclear. Postmortem, retrospective, and even longitudinal investigations are in fact biased by several factors, such as the objective difficulty to establish whether DIC might have occurred as a primary complication of burns or rather as a consequence of other superimposed pathologies (e.g., sepsis, multiple organ failure), the different diagnostic criteria for assessing DIC, and the heterogeneity of the patient samples studied. Nevertheless, the current scientific evidence is consistent with the hypothesis that biochemical changes suggestive for DIC (hypercoagulability, hypo- and hyperfibrinolysis) are commonplace in patients with burn trauma, and their severity increases exponentially with the severity of injury. Overt DIC seems to occur especially in critically ill burn patients or in those with severe burns (up to third degree) and large involvement of body surface area, in whom an appropriate therapy might be effective to prevent the otherwise fulminant course. Although early prophylaxis with antithrombin concentrates

    Directory of Open Access Journals (Sweden)

    Süleyman Akarsu


    Full Text Available Objective: Psychiatric rehabilitation has gained significance owing to improved healthcare facilities for burn injuries and decreased mortality/ morbidity rates. Burn traumas may result in psychiatric signs such as denial, anger, guilt, confusion, disgrace, anxiety, distress, and nervousness. Psychiatric disorders such as delirium, depression, anxiety, post-traumatic stress disorder, and sexual problems can also be encountered. Therefore, it is necessary to look for these signs and disorders through regular sessions with burn patients and appropriate psychometric tests. This study aims at examining the process of psychological rehabilitation for burn patients in light of the current literature. Material and Methods: This study has been carried out in the light of the main and current literature review. The study intends to put forth the data observed in the course of the psychological diagnosis, treatment and rehabilitation of burn patients. The study has been conducted in accordance with the Helsinki Declaration Guidelines. Results: Treatment and rehabilitation process requires a multidisciplinary teamwork that consists of physicians, dieticians, psychologists, social service specialists, and other healthcare workers who can meet the needs of burn patients and their families. It is necessary for the team to contribute both to the hospitalization process and the social environment of the patients and their families. Conclusion: It is observed that the quality of life of these patients can be considerably improved with the effective assessment of psychiatric signs that occur during or after the injury and with appropriate treatment methods.

    Yarrington, Cole Davis [Los Alamos National Laboratory; Obrey, Stephen J [Los Alamos National Laboratory; Foley, Timothy J [Los Alamos National Laboratory; Son, Steven F [Los Alamos National Laboratory


    The advent of widely available nanoscale energetic composites has resulted in a flurry of novel applications. One of these applications is the use of nanomaterials in energetic compositions. In compositions that exhibit high sensitivity to stimulus, these materials are often termed metastable intermolecular composites (MIC). More generally, these compositions are simply called nanoenergetics. Researchers have used many different experimental techniques to analyze the various properties of nanoenergetic systems. Among these various techniques, the confined tube burn is a simple experiment that is capable of obtaining much data related to the combustion of these materials. The purpose of this report is to review the current state of the confined tube burn experiment, including the drawbacks of the technique and possible remedies. As this report is intended to focus on the specific experimental technique, data from many different energetic materials, and experimental configurations will be presented. The qualitative and quantitative data that can be gathered using confined tube burn experiments include burning rates, total impulse, pressure rise rate, and burning rate differences between different detector types. All of these measurements lend insight into the combustion properties and mechanisms of specific nanoenergetics. Finally, certain data indicates a more complicated flow scenario which may need to be considered when developing burn tube models.

  7. The Correlation Between the Burning Features, the Burning Agent and Motivation in Burn Victims Attending Shahid Motahari Hospital in Tehran During 2009: letter to Editor

    Directory of Open Access Journals (Sweden)

    Kamran Aghakhani M.D.


    Full Text Available Burning is one of the commonest causes of death. Due to the high rate of death among burn victims epidemiological investigation of burning, burning agents and the relevant motivations can be of great preventive value.1 In this cross-sectional study all the hospitalized patients in Shahid Motahari Burn Hospital at Tehran city in the year 2009 were included in the study. The collected data were analyzed by SPSS (ver. 17 software. Out of the 1548 hospitalized patients for burn, 1134 (73.3% left hospital in good conditions, 47 (3% left in relatively good conditions, 289 (18.7% died and 78 (5% persons left the Hospital satisfactorily on their own volition. About two-thirds of the patients were men. The mean age of the burn victims was 27.9±18.3 years, 16% of them being 5 years old or younger. The highest percentage of burn area was 30% of the total body surface which was seen in 20 to 30-year old patients. 58.7% of burns had been caused by fire. 94% of the burns had happened accidentally, 5% by suicidal and 1% by homicidal acts. The highest percentage of burn was observed in patients in whom the burn agent was fire. Six (4% persons had first degree, 820 (53% persons had second degree and 722 (46.6% had third degree burns. In patients who had committed suicide third degree burns were higher than second degree burns (7.7% vs. 2%. 24.4% of women and 16.6% of men died due to the burns. The rate of death in patients less than 50 years of age was 18% but the figure increased to 24% in those above 50. A burn area less than or more than 10% was, respectively correlated with 2.1% and 22.1% of deaths. 34.8% of the patients with third degree burns and 4.6% of those with second and first degree burns died. 58.3% of the suicidal patient died due to the severity of the burns relative to 16.7% due to other causes. 89 (5.7% patients had respiratory tract burns and the death rate was 58.4% among these patients while the death rate was 16.2% in patients without

  8. History of mouth-to-mouth ventilation. Part 3: the 19th to mid-20th centuries and "rediscovery". (United States)

    Trubuhovich, Ronald V


    The start of the 19th century saw the enthusiasm of the previous one for mouth-to-mouth ventilation (MMV) dissipated. To inflate the lungs of the asphyxiated, the Royal Humane Society in the United Kingdom had recommended bellows since 1782. Principal determinants for change were aesthetic distaste for mouth-to-mouth contact and the perceived danger of using expired air, although MMV survived in the practice of some midwives. Following the 1826-9 investigations of Jean-Jacques Leroy d'Etiolles then François Magendie, all positive pressure ventilation methods were generally abandoned, after 1829 in France, and 1832 in the UK; but not chest compressions. During the next quarter century, rescuers lost understanding of the primary need for "artificial respiration", apart from researchers such as John Snow and John Erichsen, until Marshall Hall's "Ready Method" heralded the second half-century's various methods of negative pressure ventilation. Some of those methods continued in use until the 1940s. Sporadic anecdotal cases of MMV rescues were documented throughout. In the 20th century, inadequate mechanical inhalators were also tried from 1908, while obstetricians devised indirect methods of expired air ventilation (EAV). Anaesthetists in the 1940s, such as Ralph Waters, Robert Dripps, and the pair, Robert Macintosh and William Mushin, described the usefulness of MMV, and James Elam was "re-discovering" it. Following World War II, "Cold War" concerns stimulated research at the Edgewood Medical Laboratories in Maryland in the United States into the possibilities of MMV, and Elam et al confirmed and expanded on brief experiments at Oxford (United Kingdom) on the efficacy of mouth-to-tube EAV. Studies, 1957-9, by Archer Gordon, Elam and especially Peter Safar resulted in the resolution of previous airway problems, established the primacy of MMV, and incorporated it into an integrated system for basic cardiopulmonary resuscitation. Ready adoption of MMV in the US was

  9. Orion Burn Management, Nominal and Response to Failures (United States)

    Odegard, Ryan; Goodman, John L.; Barrett, Charles P.; Pohlkamp, Kara; Robinson, Shane


    An approach for managing Orion on-orbit burn execution is described for nominal and failure response scenarios. The burn management strategy for Orion takes into account per-burn variations in targeting, timing, and execution; crew and ground operator intervention and overrides; defined burn failure triggers and responses; and corresponding on-board software sequencing functionality. Burn-to- burn variations are managed through the identification of specific parameters that may be updated for each progressive burn. Failure triggers and automatic responses during the burn timeframe are defined to provide safety for the crew in the case of vehicle failures, along with override capabilities to ensure operational control of the vehicle. On-board sequencing software provides the timeline coordination for performing the required activities related to targeting, burn execution, and responding to burn failures.

    The Ti fire found in high performance engines promotes the development of burn resistant Ti alloys. The burn resistant mechanism of Ti40 alloy is investigated. Ti40 alloy reveals good burn resistance. Its interfacial products between burning products and the matrix are tenacious,which retard the diffusion of oxygen into the matrix. Two burn resistant mechanisms, that is, fast scatter dispersion of heat and suppression of oxygen diffusion, are proposed.

  11. Treatment of secondary burn wound progression in contact burns-a systematic review of experimental approaches. (United States)

    Schmauss, Daniel; Rezaeian, Farid; Finck, Tom; Machens, Hans-Guenther; Wettstein, Reto; Harder, Yves


    After a burn injury, superficial partial-thickness burn wounds may progress to deep partial-thickness or full-thickness burn wounds, if kept untreated. This phenomenon is called secondary burn wound progression or conversion. Burn wound depth is an important determinant of patient morbidity and mortality. Therefore, reduction or even the prevention of secondary burn wound progression is one goal of the acute care of burned patients. The objective of this study was to review preclinical approaches evaluating therapies to reduce burn wound progression. A systematic review of experimental approaches in animals that aim at reducing or preventing secondary burn wound progression was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) guidelines. The selected references consist of all the peer-reviewed studies performed in vivo in animals and review articles published in English, German, Italian, Spanish, or French language relevant to the topic of secondary burn wound progression. We searched MEDLINE, Cochrane Library, and Google Scholar including all the articles published from the beginning of notations to the present. The search was conducted between May 3, 2012 and December 26, 2013. We included 29 experimental studies in this review, investigating agents that maintain or increase local perfusion conditions, as well as agents that exhibit an anti-coagulatory, an anti-inflammatory, or an anti-apoptotic property. Warm water, simvastatin, EPO, or cerium nitrate may represent particularly promising approaches for the translation into clinical use in the near future. This review demonstrates promising experimental approaches that might reduce secondary burn wound progression. Nevertheless, a translation into clinical application needs to confirm the results compiled in experimental animal studies.

  12. Ceruloplasmin and Hypoferremia: Studies in Burn and Non-Burn Trauma Patients

    Directory of Open Access Journals (Sweden)

    Michael A. Dubick


    Full Text Available Objective: Normal iron handling appears to be disrupted in critically ill patients leading to hypoferremia that may contribute to systemic inflammation. Ceruloplasmin (Cp, an acute phase reactant protein that can convert ferrous iron to its less reactive ferric form facilitating binding to ferritin, has ferroxidase activity that is important to iron handling. Genetic absence of Cp decreases iron export resulting in iron accumulation in many organs. The objective of this study was to characterize iron metabolism and Cp activity in burn and non-burn trauma patients to determine if changes in Cp activity are a potential contributor to the observed hypoferremia. Material and Methods: Under Brooke Army Medical Center Institutional Review Board approved protocols, serum or plasma was collected from burn and non-burn trauma patients on admission to the ICU and at times up to 14 days and measured for indices of iron status, Cp protein and oxidase activity and cytokines. Results: Burn patients showed evidence of anemia and normal or elevated ferritin levels. Plasma Cp oxidase activity in burn and trauma patients were markedly lower than controls on admission and increased to control levels by day 3, particularly in burn patients. Plasma cytokines were elevated throughout the 14 days study along with evidence of an oxidative stress. No significant differences in soluble transferrin receptor were noted among groups on admission, but levels in burn patients were lower than controls for the first 5 days after injury. Conclusion: This study further established the hypoferremia and inflammation associated with burns and trauma. To our knowledge, this is the first study to show an early decrease in Cp oxidase activity in burn and non-burn trauma patients. The results support the hypothesis that transient loss of Cp activity contributes to hypoferremia and inflammation. Further studies are warranted to determine if decreased Cp activity increases the risk of

  13. Asymmetries in mouth opening during word generation in male stuttering and non-stuttering participants. (United States)

    Code, Chris; Lincoln, Michelle; Dredge, Rebekah


    We examined lateral asymmetries in mouth opening in right-handed male stuttering (N = 11) and non-stuttering (N = 14) participants. Lateral asymmetries in mouth opening were video-recorded and analysed in participants while they generated words beginning with the bilabial phones /b, p, m/. Non-stuttering participants showed an expected preference for right mouth opening during the task, whereas a group of stuttering participants who were matched for sex and age produced a left or bilateral pattern of mouth opening. Analysis of variance revealed the difference between the groups to be significant (p mouth asymmetries in the stuttering participants. We interpret this finding as adding some support for the hypothesis that aberrant hemispheric control for speech is involved in stuttering. Asymmetric mouth openings appear to have no direct linguistic function, and we discuss the possible implications of the phenomenon for models of speech planning and programming.

  18. Honey oil burns: a growing problem. (United States)

    Jensen, Guy; Bertelotti, Robert; Greenhalgh, David; Palmieri, Tina; Maguina, Pirko


    There is an emerging mechanism of burn injury as a result of the ignition of butane, during the manufacture of a tetrahydrocannabinol concentrate known as butane honey oil. The authors report of a series of patients who presented with this mechanism of injury and a description of the process that causes these burns. Patient data were gathered from the medical records of eight patients treated at the University of California Davis Medical Center and Shriners Hospital of Northern California. Information on the manufacturing process of butane honey oil was gathered from Internet searches and published literature on the topic. The burns witnessed at the abovementioned institutions ranged from 16 to 95% TBSA, with an average of 49.9%. The average length of stay for the patients was 118.3 hospital days and 114.4 intensive care unit days, with an average of 43.8 days spent on mechanical ventilation. The average age of patients was 22 years, with only one patient above the age of 30 years. Accidents during honey oil production have resulted in a surge of burn injuries in our community during the past year. The manufacture of this product, which involves the use of volatile butane gas, is gaining in popularity. Although considered to be safer than previous methods, multiple casualties with extensive burn injuries have resulted from this process. Associated injuries from blast trauma or chemical burns are not likely to occur in these types of explosions and have not been observed in the series reported in this article. In light of the increasing popularity of honey oil, it is important for burn care providers to gain awareness and understanding of this problem and its growing presence in the community.

  19. Angiogenin expression in burn blister fluid: implications for its role in burn wound neovascularization. (United States)

    Pan, Shin-Chen; Wu, Li-Wha; Chen, Chung-Lin; Shieh, Shyh-Jou; Chiu, Haw-Yen


    Deep partial thickness burn (DPTB) wound fluids have a greater propensity for establishing neovascularization than did superficial partial thickness burn (SPTB) wound fluids in our previous study. To investigate the factors responsible for this activity, cytokine array and enzyme-linked immunosorbent assay were used to perform an expression analysis of angiogenic factors in burn fluid. Although present in approximately equal amounts in both SPTB and DPTB blister fluids from burn patients, angiogenin does appear to be involved in the ability of DPTB blister fluid to promote neovascularization in vitro and in vivo. Angiogenin alone was sufficient to induce endothelial differentiation of circulating angiogenic cells (CAC) without vascular endothelial growth factor A involvement. In addition, angiogenin was positively associated with CAC differentiation in the burn blister fluid. Blocking the effect of angiogenin in burn blister fluids resulted in a significant reduction of endothelial cell proliferation, CAC differentiation, and new blood vessels formation in vivo. Moreover, immunohistochemistry revealed that high angiogenin expression colocalizes with high vascularity in human burn wounds at day 7, further supporting our hypothesis that angiogenin is involved in burn wound neovascularization.

  20. Radiological evaluation of facial types in mouth breathing children: a retrospective study. (United States)

    Izuka, E N; Costa, J R; Pereira, S R A; Weckx, L L M; Pignatari, S N; Uema, S F H


    Mouth breathing is a condition often associated with a long face, half-open mouth and increased anterior facial height. We performed conventional lateral and frontal cephalograms of eighty-nine children with nasal and mouth breathing and independently measured Total Facial Height using the analysis technique of Ricketts, and the Morphologic Facial Index employing the technique of Avila. It was concluded that dolicofacial following mesofacial were the most frequent patterns found in mouth-breathing children and this suggests that both analyses can be used independently.

    Full Text Available Introduction : Prevention of dental caries is one of the main strategies in contemporary pediatric dental practice. Mouth rinses are widely used as an adjunct to maintain oral hygiene. It is important for these products to be effective and safe for regular use in children. Objective : The aim of the study was to investigate the efficacy of a newly introduced xylitol, sodium fluoride and triclosan containing mouth rinse in reducing levels of plaque Streptococcus mutans and to compare it with that of a 0.12% chlorhexidine mouth rinse. Materials and Methods : Thirty children were randomly divided into two groups of 15 children each. Group I (study group was given a mouth rinse containing xylitol (5%, sodium fluoride (0.05% and triclosan (0.03% and Group II (control group was given a chlorhexidine (0.12% mouth rinse. Both mouth rinses were alcohol free. Mouth rinsing was carried out twice daily, half an hour after breakfast and half an hour following dinner, for a period of 21 days under the supervision of the investigator. Results: In both groups, there was a significant reduction in the mean S. mutans count at the end of 21 days (P < 0.001. No significant difference was observed between the two mouth rinses. Conclusion: The use of a low fluoride-xylitol based mouth rinse appears to be a suitable choice for regular use in children.

  4. A New Metric for Quantifying Burn Severity: The Relativized Burn Ratio

    Directory of Open Access Journals (Sweden)

    Sean A. Parks


    Full Text Available Satellite-inferred burn severity data have become increasingly popular over the last decade for management and research purposes. These data typically quantify spectral change between pre-and post-fire satellite images (usually Landsat. There is an active debate regarding which of the two main equations, the delta normalized burn ratio (dNBR and its relativized form (RdNBR, is most suitable for quantifying burn severity; each has its critics. In this study, we propose and evaluate a new Landsat-based burn severity metric, the relativized burn ratio (RBR, that provides an alternative to dNBR and RdNBR. For 18 fires in the western US, we compared the performance of RBR to both dNBR and RdNBR by evaluating the agreement of these metrics with field-based burn severity measurements. Specifically, we evaluated (1 the correspondence between each metric and a continuous measure of burn severity (the composite burn index and (2 the overall accuracy of each metric when classifying into discrete burn severity classes (i.e., unchanged, low, moderate, and high. Results indicate that RBR corresponds better to field-based measurements (average R2 among 18 fires = 0.786 than both dNBR (R2 = 0.761 and RdNBR (R2 = 0.766. Furthermore, the overall classification accuracy achieved with RBR (average among 18 fires = 70.5% was higher than both dNBR (68.4% and RdNBR (69.2%. Consequently, we recommend RBR as a robust alternative to both dNBR and RdNBR for measuring and classifying burn severity.

    Emami, Seyed-Abolhassan; Motevalian, Seyed Abbas; Momeni, Mahnoush; Karimi, Hamid


    Defining the epidemiology and outcome of geriatric burn patients is critical for specialized burn centers, health-care workers, and governments. Better resource use and effective guidelines are some of the advantages of studies focusing on this aspect. The outcome of these patients serves as an objective criterion for quality control, research, and preventive programs. We used data from the burn registry program in our country. For 2 years, >28,700 burn patients were recorded, 1721 of whom were admitted. Among them, 187 patients were ≥55 years old. Sixty-nine percent of patients were male and 31% female, with a male to female ratio of 2.22:1. The mean±standard deviation (SD) of age was 63.4±8.1. The cause of burns was flame (58.2%) and scalds (20.3%). Most of the burns were sustained at home. The mean duration of hospital stay was 19.5 days (range 3-59 days). The mean (SD) of the total body surface area (TBSA) was 20.3% (8.4%). The median hospital stay (length of stay (LOS)) was 11 days (SD=14). The increase in TBSA was related to a longer LOS (pBurn wound infection developed in 44.3% of patients. The presence of inhalation injury was significantly related to mortality (ppatients, 9% recovered completely, 74.9% recovered partially (requiring further treatment), 1% underwent amputation, and 12.8% died. The lack of insurance coverage did not affect the survival of our geriatric burn patients. However, being alone or single, ignition of clothing, cause of burn, comorbid illnesses, complications following the burn, TBSA, age, and sepsis were positively correlated with mortality. The mean cost of treatment for each patient was about $7450.

    Closed-mouth bone scintigraphy (CM scan) and closed-mouth single-photon emission computed tomography (CM SPECT) are used for conventional evaluation of osteoarthritis of the temporomandibular joint (TMJ). However, the adequacy of open-mouth bone scintigraphy (OM scan) has not yet been evaluated. Therefore, the purpose of this study was to compare the diagnostic performance of CM scan, CM SPECT, and OM scan. Thirty-six patients with suspicion of an abnormality of the TMJ and who underwent a 99mTc-HDP CM scan, CM SPECT, and an OM scan were enrolled. The scans were assessed visually for the presence of positive focal uptake in the TMJ. Osteoarthritis was defined as arthralgia plus crepitus or radiologic signs of arthrosis. Of 72 TMJs, 21 (29.2 %) were diagnosed with osteoarthritis. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 90.5 %, 49.0 %, 42.2 %, 92.6 % and 61.1 % for the CM scan, 81.0 %, 58.8 %, 44.7 %, 88.2 % and 65.3 % for CM SPECT, and 81.0 %, 82.4 %, 65.4 %, 91.3 % and 81.9 % for the OM scan, respectively. The accuracy of the OM scan was higher than that of CM SPECT and the CM scans (p = 0.004 and p < 0.001, respectively). The OM scan was more accurate than the conventional CM scan and even CM SPECT for diagnosing TMJ osteoarthritis.

    Haykiri-Acma, H.; Yaman, S.; Kucukbayrak, S. [Istanbul Technical University, Chemical and Metallurgical Engineering Faculty, Chemical Engineering Department, 34469 Maslak, Istanbul (Turkey)


    This study was performed to investigate the burning characteristics of isolated fractions of a biomass species. So, woody shells of hazelnut were chemically treated to obtain the fractions of extractives-free bulk, lignin, and holocellulose. Physical characterization of these fractions were determined by SEM technique, and the burning runs were carried out from ambient to 900 C applying thermal analysis techniques of TGA, DTG, DTA, and DSC. The non-isothermal model of Borchardt-Daniels was used to DSC data to find the kinetic parameters. Burning properties of each fraction were compared to those of the raw material to describe their effects on burning, and to interpret the synergistic interactions between the fractions in the raw material. It was found that each of the fractions has its own characteristic physical and thermal features. Some of the characteristic points on the thermograms of the fractions could be followed definitely on those of the raw material, while some of them seriously shifted to other temperatures or disappeared as a result of the co-existence of the ingredients. Also, it is concluded that the presence of hemicellulosics and celluloses makes the burning of lignin easier in the raw material compared to the isolated lignin. The activation energies can be arranged in the order of holocellulose < extractives-free biomass < raw material < lignin. (author)

    Rogers, Alan David; Deal, Cailin; Argent, Andrew Charles; Hudson, Donald Anthony; Rode, Heinz


    More than three-quarters of deaths related to major burns are a consequence of infection, which is frequently ventilator associated pneumonia (VAP). A retrospective study was performed, over a five-year period, of ventilated children with major burns. 92 patients were included in the study; their mean age was 3.5 years and their mean total body surface area burn was 30%. 62% of the patients sustained flame burns, and 31% scalds. The mean ICU stay was 10.6 days (range 2-61 days) and the mean ventilation time was 8.4 days (range 2-45 days). There were 59 documented episodes of pneumonia in 52 patients with a rate of 30 infections per 1000 ventilator days. Length of ventilation and the presence of inhalational injury correlate with the incidence of VAP. 17.4% of the patients died (n=16); half of these deaths may be attributed directly to pneumonia. Streptococcus pneumonia, Pseudomonas aeruginosa, Acinetobacter baumanii and Staphylococcus aureus were the most prominent aetiological organisms. Broncho-alveolar lavage was found to be more specific and sensitive at identifying the organism than other methods. This study highlights the importance of implementing strictly enforced strategies for the prevention, detection and management of pneumonia in the presence of major burns.

    Leandro Dario Faustino

    Full Text Available CONTEXT: Electrical burns are an important etiology in dealing with patients suffering from burns. In situations of extensive deep lesions of multiple organs and systems affecting young and economically active people, there is a need for expensive multidisciplinary treatment, with a high socioeconomic cost for the community. Among the permanent injuries that explain this high cost, eye injuries stand out, since they are widely disabling. Although rare, lesions of the posterior segment of the eye are associated with higher incidence of major sequelae, and thus deserve special attention for dissemination and discussion of the few cases observed.CASE REPORT: The authors report the case of a patient who suffered high-voltage electrical burns and presented bilateral maculopathy, which evolved with a need for a surgical approach to repair retinal detachment and permanent low visual acuity.CONCLUSION: This report highlights the rarity of the etiology of maculopathy and the need for campaigns for prevention not only of burns in general, but also especially of electrical burns.

  10. Increased mortality in hypernatremic burned patients

    Directory of Open Access Journals (Sweden)

    Lange, Thomas


    Full Text Available Introduction: In-hospital hypernatremia develops usually iatrogenically from inadequate or inappropriate fluid prescription. In severely burned patient an extensive initial fluid resuscitation is necessary for burn shock survival. After recovering of cellular integrity the circulating volume has to be normalized. Hereby extensive water and electrolyte shifts can provoke hypernatremia. Purpose: Is a hypernatremic state associated with increased mortality? Method: Retrospective study for the incidence of hypernatremia and survival in 40 patients with a totally burned surface area (TBSA >10%. Age, sex, TBSA, ABSI-Score and fluid resuscitation within the first 24 hours were analyzed. Patients were separated in two groups without (Group A or with (Group B hypernatremia. Results: Hypernatremia occurred on day 5±1.4. No significant difference for age, sex, TBSA, ABSI-Score and fluid resuscitation within the first 24 hours were calculated. In Group A all patients survived, while 3 of the hypernatremic patient in Group B died during ICU-stay (Odds-ratio = 1.25; 95% CI 0.971–1.61; p=0.046. Conclusion: Burned patients with an in-hospital acquired hypernatremia have an increased mortality risk. In case of a hypernatremic state early intervention is obligatory. There is a need of a fluid removal strategy in severely burned patient to avoid water imbalance.

  12. Burn wound: How it differs from other wounds?

    Directory of Open Access Journals (Sweden)

    V K Tiwari


    Full Text Available Management of burn injury has always been the domain of burn specialists. Since ancient time, local and systemic remedies have been advised for burn wound dressing and burn scar prevention. Management of burn wound inflicted by the different physical and chemical agents require different regimes which are poles apart from the regimes used for any of the other traumatic wounds. In extensive burn, because of increased capillary permeability, there is extensive loss of plasma leading to shock while whole blood loss is the cause of shock in other acute wounds. Even though the burn wounds are sterile in the beginning in comparison to most of other wounds, yet, the death in extensive burns is mainly because of wound infection and septicemia, because of the immunocompromised status of the burn patients. Eschar and blister are specific for burn wounds requiring a specific treatment protocol. Antimicrobial creams and other dressing agents used for traumatic wounds are ineffective in deep burns with eschar. The subeschar plane harbours the micro-organisms and many of these agents are not able to penetrate the eschar. Even after complete epithelisation of burn wound, remodelling phase is prolonged. It may take years for scar maturation in burns. This article emphasizes on how the pathophysiology, healing and management of a burn wound is different from that of other wounds.

  13. Atypical streptococcal infection of gingiva associated with chronic mouth breathing. (United States)

    Haytac, M Cenk; Oz, I Attila


    Streptococcal infections of oral tissues are mainly seen in young children who experience a variety of upper respiratory tract infections. The disease is characterized by fever, lymphadenopathy, and ulcers on the gingiva, lips, and tonsils. This case report presents an atypical streptococcal infection of the gingiva in an 18-year-old man. The patient was referred to the periodontology department complaining of a 2-month history of gingival enlargement. He had persistent fever (39.5 degrees C) and general malaise for 2 weeks. Intraoral examination revealed extremely inflamed and enlarged gingiva with spontaneous bleeding and suppuration. Based on the otolaryngologic consultation and the hematologic, immunologic, and microbiologic tests, the final diagnosis was an atypical streptococcal gingivitis with chronic adenoid-related mouth breathing and oral hygiene neglect as contributing factors. Treatment consisted of a broad-spectrum antibiotic regimen, supragingival and subgingival debridement, adenoidectomy, and scaling and root planing. A good response to nonsurgical therapy was achieved despite poor patient compliance, and no recurrence of gingival enlargement was observed after 1 year. Streptococcal gingivitis should be included in the differential diagnosis of suppurative gingival enlargements. Furthermore, chronic mouth breathing may initiate and/or contribute to this disease.

  14. [Foot-and-mouth disease and its differential diagnoses]. (United States)

    Teifke, J P; Breithaupt, A; Haas, B


    Foot-and-mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed animals, which leads to the formation of vesicles, erosions und ulcerations in the mouth and hairless parts of the skin, in particular on the feet. Due to its dramatic economic consequences, FMD is considered to be one of the most important diseases of animals. There is a permanent risk of introduction of the virus into Europe due to travel and illegal importation of agricultural products. Cloven-hoofed animals (cattle, sheep, goats, pigs and related game animals) are the typical hosts of the FMD virus. However, some zoo and wild animals belonging to other taxonomical groups, such as giraffes, elephants and camels, are also susceptible. Stomatitis and infections of the feet in livestock occur quite frequently, and often the causes of these conditions remain obscure. Sometimes, a differentiation from FMD is not possible on the basis of clinical signs and gross lesions, necessitating further laboratory investigations. This applies in particular to cases caused by the agents of vesicular stomatitis (VS) and swine vesicular disease (SVD). Additionally, other infectious agents can cause stomatitis, e.g. the viruses of mucosal disease (MD), malignant catarrhal fever (MCF), rinderpest, peste des petits ruminants (PPR), papular stomatitis, orf, blue tongue (BT) and epizootic haemorrhagic disease (EHD). In sheep, a stomatitis of unclear etiology was described as "OMAGOD". Furthermore, bacteria, chemicals and mechanical trauma can cause stomatitis and pododermatitis.

  16. Giant sand waves at the mouth of San Francisco Bay (United States)

    Barnard, P.L.; Hanes, D.M.; Rubin, D.M.; Kvitek, R.G.


    A field of giant sand waves, among the largest in the world, recently was mapped in high resolution for the first time during a multibeam survey in 2004 and 2005 through the strait of the Golden Gate at the mouth of San Francisco Bay in California (Figure la). This massive bed form field covers an area of approximately four square kilometers in water depths ranging from 30 to 106 meters, featuring more than 40 distinct sand waves with crests aligned approximately perpendicular to the dominant tidally generated cross-shore currents, with wavelengths and heights that measure up to 220 meters and 10 meters, respectively. Sand wave crests can be traced continuously for up to two kilometers across the mouth of this energetic tidal inlet, where depth-averaged tidal currents through the strait below the Golden Gate Bridge exceed 2.5 meters per second during peak ebb flows. Repeated surveys demonstrated that the sand waves are active and dynamic features that move in response to tidally generated currents. The complex temporal and spatial variations in wave and tidal current interactions in this region result in an astoundingly diverse array of bed form morphologies, scales, and orientations. Bed forms of approximately half the scale of those reported in this article previously were mapped inside San Francisco Bay during a multibeam survey in 1997 [Chin et al., 1997].

    Pratikkumar Joshi


    Full Text Available The present investigation was undertaken with the objective of formulating mouth dissolving film(s of the antiemetic drug Domperidone to enhance the convenience and compliance by the elderly and pediatric patients. Domperidone is a drug of choice in case of nausea and vomiting produced by chemotherapy, migraine headaches, food poisoning and viral infections. It causes dopamine (D2 and D3 receptor blockage both at the chemoreceptor trigger zone and at the gastric level. It shows high first pass metabolism which results in poor bioavailability (10-15%. In view of high first pass metabolism and short plasma half-life it is an ideal candidate for rapid release drug delivery system. The solid dispersions of Domperidone were prepared with the use β-cyclodextrin in various ratios (1:1, 1:2, 1:3 and solubility study was performed to determine the ratio in which solubility of Domperidone was highest (1:3. The selected solid dispersions were then utilized for the preparation of film by solvent casting method utilizing HPMC E15 as a film forming agent and PEG-400 as plasticizer. Five formulae were prepared and were evaluated for their in vitro dissolution characteristics, in vitro disintegration time, and their physico-mechanical properties. The promising film (F1 showed the greatest drug dissolution (more than 75% within 15 min, satisfactory in vitro disintegration time (45 sec and physico-mechanical properties that are suitable for mouth dissolving films.

    Mohammad Mehdi Soltan Dallal


    Full Text Available Background: Burns and its complications are regarded as a major problem in the society. Skin injuries resulted from ultraviolet radiation, radioactivity, electricity or chemicals as well as respiratory damage from smoke inhalation are considered burns. This study aimed to determine the epidemiology and outcome of burn patients admitted to Motahari Hospital, Tehran, Iran. Methods: Two hundred patients with second-degree burns admitted to Motahari Referral Center of Burn in Tehran, Iran. They were studied during a period of 12 months from May 2012 to May 2013. During the first week of treatment swabs were collected from the burn wounds after cleaning the site with sterile normal saline. Samples were inoculated in blood agar and McConkey agar, then incubation at 37 C for 48 hours. Identification was carried out according to standard conventional biochemical tests. Treatment continued up to epithelial formation and wound healing. Results of microbial culture for each patient was recorded. Healing time of the burn wounds in patients was recorded in log books. Chi-square test and SPSS Software v.19 (IBM, NY, USA were used for data analysis. Results: Our findings indicate that the most causes of burns are hot liquids in 57% of cases and flammable liquid in 21% of cases. The most cases of burns were found to be in the range of 21 to 30 percent with 17.5% and 7% in male and female respectively. Gram-negative bacteria were dominated in 85.7% and among them pseudomonas spp. with 37.5% were the most common cause of infected burns, followed by Enterobacter, Escherichia coli, Staphylococcus aureus, Acinetobacter and Klebsiella spp. Conclusion: The results of this study showed that the most cause of burns in both sex is hot liquid. Men were more expose to burn than women and this might be due to the fact that men are involved in more dangerous jobs than female. Pseudomonas aeruginosa was the most common organism encountered in burn infection.

    Fusion research and development has two aspects. One is an academic research on science and technology, i.e., discovery and understanding of unexpected phenomena and, development of innovative technology, respectively. The other is energy source development to realize fusion as a viable energy future. Fusion research has been made remarkable progress in the past several decades, and ITER will soon realize burning plasma that is essential for both academic research and energy development. With ITER, scientific research on unknown phenomena such as self-organization of the plasma in burning state will become possible and it contributes to create a variety of academic outcome. Fusion researchers will have a responsibility to generate actual energy, and electricity generation immediately after the success of burning plasma control experiment in ITER is the next important step that has to be discussed seriously.

    Cohen, Laurence; Angot, Emilie; Goria, Odile; Koning, Edith; François, Arnaud; Sabourin, Jean-Christophe


    Ischemic cholangiopathy is a recently described entity occurring mainly after hepatic grafts. Very few cases after intensive care unit (ICU) for extended burn injury were reported. We report the case of a 73-year-old woman consulting in an hepatology unit, for a jaundice appearing during a hospitalisation in an intensive care unit and increasing from her leaving from ICU, where she was treated for an extended burn injury. She had no pre-existing biological features of biliary disease. Biological tests were normal. Magnetic resonance imaging acquisitions of biliary tracts pointed out severe stenosing lesions of diffuse cholangiopathy concerning intrahepatic biliary tract, mainly peri-hilar. Biopsie from the liver confirmed the diagnosis, showing a biliary cirrhosis with bile infarcts. This case is the fourth case of ischemic cholangiopathy after extended burn injury, concerning a patient without a prior history of hepatic or biliary illness and appearing after hospitalisation in intensive care unit.

    Roock, Sophie D; Deleuze, Jean-Paul; Rose, Thomas; Jennes, Serge; Hantson, Philippe


    Assault chemical burns are uncommon in northern Europe. Besides local toxicity, systemic manifestations are possible after strong acid exposure. A 40-year-old woman was admitted 1 h after a criminal assault with sulfuric acid. The total burned surface area was 35%, third degree. Injury was due to sulfuric acid (measured pH 0.9) obtained from a car battery. Immediate complications were obstructive dyspnea and metabolic acidosis. The admission arterial pH was 6.92, with total bicarbonate 8.6 mEq/l and base deficit 23.4 mEq/l. The correction of metabolic acidosis was achieved after several hours by the administration of bicarbonate and lactate buffers. The patient developed several burns-related complications (sepsis and acute renal failure). Cutaneous projections of strong acids may cause severe metabolic acidosis, particularly when copious irrigation and clothes removal cannot be immediately performed at the scene.

  3. Fungal infections in burns: Diagnosis and management

    Directory of Open Access Journals (Sweden)

    Capoor Malini


    Full Text Available Burn wound infection (BWI is a major public health problem and the most devastating form of trauma worldwide. Fungi cause BWI as part of monomicrobial or polymicrobial infection, fungaemia, rare aggressive soft tissue infection and as opportunistic infections. The risk factors for acquiring fungal infection in burns include age of burns, total burn size, body surface area (BSA (30-60%, full thickness burns, inhalational injury, prolonged hospital stay, late surgical excision, open dressing, artificial dermis, central venous catheters, antibiotics, steroid treatment, long-term artificial ventilation, fungal wound colonisation (FWC, hyperglycaemic episodes and other immunosuppressive disorders. Most of the fungal infections are missed owing to lack of clinical awareness and similar presentation as bacterial infection coupled with paucity of mycology laboratories. Expedient diagnosis and treatment of these mycoses can be life-saving as the mortality is otherwise very high. Emergence of resistance in non-albicans Candida spp., unusual yeasts and moulds in fungal BWI, leaves very few fungi susceptible to antifungal drugs, leaving many patients susceptible. There is a need to speciate fungi as far as the topical and systemic antifungal is concerned. Deep tissue biopsy and other relevant samples are processed by standard mycological procedures using direct microscopy, culture and histopathological examination. Patients with FWC should be treated by aggressive surgical debridement and, in the case of fungal wound infection (FWI, in addition to surgical debridement, an intravenous antifungal drug, most commonly amphotericin B or caspofungin, is prescribed followed by de-escalating with voriconazole or itraconazole, or fluconazole depending upon the species or antifungal susceptibility, if available. The propensity for fungal infection increases, the longer the wound is present. Therefore, the development of products to close the wound more rapidly

  4. Soil heating and impact of prescribed burning (United States)

    Stoof, Cathelijne


    Prescribed burning is highly uncommon in the Netherlands, where wildfire awareness is increasing but its risk management does not yet include fuel management strategies. A major exception is on two military bases, that need to burn their fields in winter and spring to prevent wildfires during summer shooting practice. Research on these very frequent burns has so far been limited to effects on biodiversity, yet site managers and policy makers have questions regarding the soil temperatures reached during these burns because of potential impact on soil properties and soil dwelling fauna. In March 2015, I therefore measured soil and litter temperatures under heath and grass vegetation during a prescribed burn on military terrain in the Netherlands. Soil and litter moisture were sampled pre- and post-fire, ash was collected, and fireline intensity was estimated from flame length. While standing vegetation was dry (0.13 g water/g biomass for grass and 0.6 g/g for heather), soil and litter were moist (0.21 cm3/cm3 and 1.6 g/g, respectively). Soil heating was therefore very limited, with maximum soil temperature at the soil-litter interface remaining being as low as 6.5 to 11.5°C, and litter temperatures reaching a maximum of 77.5°C at the top of the litter layer. As a result, any changes in physical properties like soil organic matter content and bulk density were not significant. These results are a first step towards a database of soil heating in relation to fuel load and fire intensity in this temperate country, which is not only valuable to increase understanding of the relationships between fire intensity and severity, but also instrumental in the policy debate regarding the sustainability of prescribed burns.

  5. Biomass Burning Observation Project Science Plan

    Energy Technology Data Exchange (ETDEWEB)

    Kleinman, KI [Brookhaven National Laboratory; Sedlacek, AJ [Brookhaven National Laboratory


    Aerosols from biomass burning perturb Earth’s climate through the direct radiative effect (both scattering and absorption) and through influences on cloud formation and precipitation and the semi-direct effect. Despite much effort, quantities important to determining radiative forcing such as the mass absorption coefficients (MAC) of light-absorbing carbon, secondary organic aerosol (SOA) formation rates, and cloud condensation nuclei (CCN) activity remain in doubt. Field campaigns in northern temperate latitudes have been overwhelmingly devoted to other aerosol sources in spite of biomass burning producing about one-third of the fine particles (PM2.5) in the U.S.

  6. Effect of Topical Platelet-Rich Plasma on Burn Healing After Partial-Thickness Burn Injury. (United States)

    Ozcelik, Umit; Ekici, Yahya; Bircan, Huseyin Yuce; Aydogan, Cem; Turkoglu, Suna; Ozen, Ozlem; Moray, Gokhan; Haberal, Mehmet


    BACKGROUND To investigate the effects of platelet-rich plasma on tissue maturation and burn healing in an experimental partial-thickness burn injury model. MATERIAL AND METHODS Thirty Wistar albino rats were divided into 3 groups of 10 rats each. Group 1 (platelet-rich plasma group) was exposed to burn injury and topical platelet-rich plasma was applied. Group 2 (control group) was exposed to burn injury only. Group 3 (blood donor group) was used as blood donors for platelet-rich plasma. The rats were killed on the seventh day after burn injury. Tissue hydroxyproline levels were measured and histopathologic changes were examined. RESULTS Hydroxyproline levels were significantly higher in the platelet-rich plasma group than in the control group (P=.03). Histopathologically, there was significantly less inflammatory cell infiltration (P=.005) and there were no statistically significant differences between groups in fibroblast development, collagen production, vessel proliferations, or epithelization. CONCLUSIONS Platelet-rich plasma seems to partially improve burn healing in this experimental burn injury model. As an initial conclusion, it appears that platelet-rich plasma can be used in humans, although further studies should be performed with this type of treatment.

  7. Burns in patients over 90: a fifteen-year series from a regional burns centre. (United States)

    Shariff, Zakir; Rodrigues, Jeremy N; Anwar, Umair; Austin, Orla; Phipps, Alan


    The elderly constitute an expanding subgroup within society, and may have differences in health needs compared to younger patients. The specific needs and outcomes of elderly patients with burns have been widely studied. However, the definition of elderly often used in previous studies is a cut off of 65 years old. Within this broadly defined group, the very elderly may have distinct health care needs and issues. This study investigated aetiology, management and outcome of burns in those over 90 years treated at a single UK burns service over a period of 15 years between 1998 and 2013, and compares these data to published data describing 'younger' elderly burns patients. Twenty two patients were included, with a 2:1 female:male ration, and a mean 9%TBSA burn. Six of the 22 died during their admission, and those who survived averaged 8 days inpatient stay per %TBSA. The very elderly with burns may fare worse than younger elderly patients. Although burns in the very elderly are relatively infrequent events, they require significant resource. Further work to optimise their outcome is required.

  8. Financial burden of burn injuries in iran: a report from the burn registry program. (United States)

    Karimi, H; Motevalian, S A; Momeni, M; Ghadarjani, M


    Understanding the cost of burn treatment is very important for patients, their families, governmental authorities and insurance companies. It alleviates patient and familial stress, provides a framework for better use of resources, and facilitates better performance between burn centers. Hospital burn costs can provide a basis for authorities to budget for acute burn treatment, for further management of chronic complications, and for planning prevention and public educational programs in Iran. To identify costs we used data from our burn registry program. Over the two-year assessment period, we treated roughly 28,700 burn patients, 1,721 of whom were admitted, with a mortality rate of 5.9%. The male to female ratio was 1.7:1 (63% male; 37% female). Flame burns were most frequent (49.8%) followed by scalds (35.7%). Mean hospital stay was 14.41 days (range 0-64 days). Mean TBSA was 17.39%. Skin grafts were carried out in 65.4% of the patients, with a mean of 5.2 surgeries per patient. The total cost of all patient admissions over the two years was US$ 4,835,000. The maximum treatment cost for one patient was US$ 91,000. The mean cost per patient was US$ 2,810 (29,500,000 Rials). The mean cost for each percent of burn was US$ 162. The mean cost for a one-day stay in hospital was US$ 195. The mean cost of each operation was US$ 540. Patients who contracted infections endured longer hospital stays, meaning increased costs of US$ 195 per day. With comparable outcome and results, the cost of burn treatment in Iran is cheaper than in the US and Europe.

  9. "Burn catatonia": a case report and literature review. (United States)

    Quinn, Davin Kenneth


    Thermal injuries have been recognized to cause significant neuropsychiatric symptoms and disability in their sufferers since the middle of the 20th century, when Drs. Stanley Cobb and Erich Lindemann of the Massachusetts General Hospital (Boston, MA) studied survivors of the Cocoanut Grove nightclub fire in Boston. Although "burn encephalopathy" or burn-induced delirium is a common occurrence in the acute phase, catatonia in burn patients is not often reported. This report describes a case of malignant catatonia occurring in a 51-year-old male patient acutely suffering from burns acquired in a chemical explosion, effectively treated with reinstitution of a selective serotonin reuptake inhibitor. The literature on burn encephalopathy and catatonia in burns is reviewed. Few examples of burn catatonia exist. Burn encephalopathy is common, and may occur in patients with low TBSA burns such as described in the case above. Descriptions of burn encephalopathy are numerous, but have not included catatonia as a possible etiology. Catatonia in burn patients as an etiology of burn encephalopathy is likely underrecognized. Clinicians should be aware of the possibility of catatonia when a patient's confusional state after a burn does not respond to usual care.

  1. Clinker burning kinetics and mechanism

    Energy Technology Data Exchange (ETDEWEB)

    Telschow, S.


    The industrial cement process is subject to several changes in order to reduce the high energy consumption and thereby increase the profitability of cement production. These changes also affect the core of the entire cement producing process: the clinker formation in the rotary kiln. Thus, in order to maintain or even improve clinker quality (and output), we need a better understanding of the development of clinker properties inside the kiln to react upon the impact of process changes. Clinker formation in industrial rotary kilns is very complex due to a vast number of interacting parameters: kiln dimensions, rotation velocity, temperature, gas composition, heat transfer phenomena, etc. These conditions can only be partly simulated in ordinary lab-scale experiments. Thus, the objectives of this project have been to establish test equipment to simulate the industrial clinker burning process on a laboratory scale and to conduct clinker formation experiments in order to derive knowledge on gradual clinker property development, as a function of different process parameters. A new lab-scale setup rotary kiln simulator (RKS) was designed and built for this purpose. It is assembled of two parts: an ordinary lab-scale heating furnace and a sample motion system. The motion system consists of a SiC tube, which moves the sample, placed in a Pt/Rh-crucible, at a chosen velocity through the heating furnace. Simultaneously, the sample is rotated around its horizontal axis with a chosen rotation velocity. The heating furnace consists of five individual heating zones, which are set to obtain a temperature ramp from {approx}00-1540 deg. C. Furthermore, the atmosphere in the system can be set to any mixture of N2, O2 and CO{sup 2}. Thus, the rotary kiln simulator features most important parameters of the industrial cement rotary kiln (ICRK): gradual temperature increase, rotation velocity and gas phase composition. An investigation of clinker formation vs. heating profile and

  2. Tapping the grapevine: a closer look at word-of-mouth as a recruitment source. (United States)

    Van Hoye, Greet; Lievens, Filip


    To advance knowledge of word-of-mouth as a company-independent recruitment source, this study draws on conceptualizations of word-of-mouth in the marketing literature. The sample consisted of 612 potential applicants targeted by the Belgian Defense. Consistent with the recipient-source framework, time spent receiving positive word-of-mouth was determined by the traits of the recipient (extraversion and conscientiousness), the characteristics of the source (perceived expertise), and their mutual relationship (tie strength). Only conscientiousness and source expertise were determinants of receiving negative word-of-mouth. In line with the accessibility-diagnosticity model, receiving positive employment information through word-of-mouth early in the recruitment process was positively associated with perceptual (organizational attractiveness) and behavioral outcomes (actual application decisions), beyond potential applicants' exposure to other recruitment sources.

  3. Skeletal and occlusal characteristics in mouth-breathing pre-school children. (United States)

    Mattar, Sara Elisa M; Anselmo-Lima, Wilma T; Valera, Fabiana C P; Matsumoto, Mirian A N


    This study verified the influence of chronic mouth breathing on dentofacial growth and developmental in pre-school children. The study evaluated 73 children, both sexes, ranging from 3 to 6 years of age. After the otorhinolaryngological breathing diagnosis, 44 mouth-breathing children and 29 nasal-breathing children were compared according to facial and occlusal characteristics. The skeletal pattern measurements SN.GoGn, BaN.PtGn, PP.PM, Ar-Go, S-Go indicated a tendency to mouth-breathing children presenting a dolicofacial pattern. According to occlusal characteristics, only the intermolar distance showed a significant correlation with a narrow maxillary arch in mouth-breathing subjects. Based on the results of this study, mouth-breathing can influence craniofacial and occlusal development early in childhood.

    The aim of this study was to examine the effect of mouth breathing on masticatory muscle activity during chewing food. Masseter muscle activity during chewing of a rice ball was recorded in 45 adult volunteers (three women), identified as nose breathers. Surface electrodes were placed on the skin according to the orientation of the masseter muscle to record the activity of this muscle while the subjects chewed the food until swallowing. Each activity was recorded twice, once with nose breathing and once with mouth breathing induced by nasal obstruction. The integrated and mean electromyography values for mouth breathing were significantly lower than the values for nose breathing (P mouth breathing compared with nose breathing (P mouth breathing decreases chewing activity and reduces the vertical effect upon the posterior teeth.

  5. Mouth breathing: adverse effects on facial growth, health, academics, and behavior. (United States)

    Jefferson, Yosh


    The vast majority of health care professionals are unaware of the negative impact of upper airway obstruction (mouth breathing) on normal facial growth and physiologic health. Children whose mouth breathing is untreated may develop long, narrow faces, narrow mouths, high palatal vaults, dental malocclusion, gummy smiles, and many other unattractive facial features, such as skeletal Class II or Class III facial profiles. These children do not sleep well at night due to obstructed airways; this lack of sleep can adversely affect their growth and academic performance. Many of these children are misdiagnosed with attention deficit disorder (ADD) and hyperactivity. It is important for the entire health care community (including general and pediatric dentists) to screen and diagnose for mouth breathing in adults and in children as young as 5 years of age. If mouth breathing is treated early, its negative effect on facial and dental development and the medical and social problems associated with it can be reduced or averted.

    Full Text Available Maxillofacial structures and mouth breathing patients constitute an especially interesting topic in orthodontic literature. The present study aims at determining the possible correlations between the anteroposterior and vertical dimensions of the pharynx and the craniofacial morphology in these patients. Materials and method. Prior to the orthodontic treatment, measurements were performed on 90 teleradiographies of some children aged between 8 and 13, with Class I, II and III anomalies, after which the anteroposterior and vertical dimensions of the pharynx and the skeletal craniofacial morphology were statistically compared. Results and discussion. Correlations have been established between the nasopharyngeal and craniofacial variables. Nasopharyngeal depth increases in skeletal Class II- and decreases in skeletal Class III-cases, while the discrepancy is represented by either the ANB angle or AOBO value. No significant differences between ages were recorded. Conclusions. Obstruction of the nasopharynx can be – in some specific cases – statistically significant, being related to a specific craniofacial morphology.

    Full Text Available Metformin HCl is a biguanide antihyperglycemic agent used for treating non-insulin-dependent diabetes mellitus (NIDDM. It improves glycemic control by decreasing hepatic glucose production, decreasing glucose absorption and increasing insulin-mediated glucose uptake. In the present study an attempt has been made to prepare fast dissolving tablets of Metformin HCl in the oral cavity with enhanced dissolution rate. The tablets were prepared with three superdisintegrants e.g:, Croscarmellose sodium, Sodium starch glycolate and Crospovidone. The blend was examined for angle of repose, bulk density, tapped density, compressibility index and hausners ratio. The tablets were evaluated for hardenss, friability, disintegration time, dissolution rate,drug content, and were found to be within 1 min. It was concluded that the mouth dissolving tablets with proper hardness, rapidly disintegrating with enhanced dissolution can be made using selected superdisintegrants.

  12. Carbohydrate mouth rinse: does it improve endurance exercise performance?

    Directory of Open Access Journals (Sweden)

    Painelli Vitor


    Full Text Available Abstract It is well known that carbohydrate (CHO supplementation can improve performance in endurance exercises through several mechanisms such as maintenance of glycemia and sparing endogenous glycogen as well as the possibility of a central nervous-system action. Some studies have emerged in recent years in order to test the hypothesis of ergogenic action via central nervous system. Recent studies have demonstrated that CHO mouth rinse can lead to improved performance of cyclists, and this may be associated with the activation of brain areas linked to motivation and reward. These findings have already been replicated in other endurance modalities, such as running. This alternative seems to be an attractive nutritional tool to improve endurance exercise performance.

  13. Modelling vaccination strategies against foot-and-mouth disease (United States)

    Keeling, M. J.; Woolhouse, M. E. J.; May, R. M.; Davies, G.; Grenfell, B. T.


    Vaccination has proved a powerful defence against a range of infectious diseases of humans and animals. However, its potential to control major epidemics of foot-and-mouth disease (FMD) in livestock is contentious. Using an individual farm-based model, we consider either national prophylactic vaccination campaigns in advance of an outbreak, or combinations of reactive vaccination and culling strategies during an epidemic. Consistent with standard epidemiological theory, mass prophylactic vaccination could reduce greatly the potential for a major epidemic, while the targeting of high-risk farms increases efficiency. Given sufficient resources and preparation, a combination of reactive vaccination and culling might control ongoing epidemics. We also explore a reactive strategy, `predictive' vaccination, which targets key spatial transmission loci and can reduce markedly the long tail that characterizes many FMD epidemics. These analyses have broader implications for the control of human and livestock infectious diseases in heterogeneous spatial landscapes.

    Full Text Available The Garigliano Plain (between Latium and Campania is characterized by the presence of wetlands behind the most recent beach ridge. Although modern cartography displays small lakes and the Greek and Latin authors describe a marshy environment close to the river mouth, it is not easy to define the nature of these wetlands and the relationship between the environment and the human presence. This research aims to reconstruct the evolution of the coastal landscape with a multidisciplinary approach that combines the typical analysis from archaeology, topography, geomorphology and palynology. In this paper we have focused on pollen analyses, that reveal an environment characterized by wetland vegetation. In the whole pollen diagram the anthropogenic indicators are very low so the cultivated fields appear to be far from the studied area.

  15. Word of mouth and universal voting behaviour in proportional elections

    CERN Document Server

    Fortunato, S; Castellano, Claudio; Fortunato, Santo


    Human societies exhibit many examples of nontrivial collective behaviour generated by the interaction of a large number of individuals. To characterize these emergent phenomena and understand their origin it is crucial to discover regularities in the macroscopic patterns of data describing collective social phenomena. Elections are a prominent example of collective social phenomenon, and a quantitative statistical analysis has begun. Here we show that, in proportional elections, the distribution of the number of votes received by candidates is universal, i.e. it is the same function in different countries and years, when the number of votes is rescaled according to the strength of the party each candidate belongs to. A simple dynamical model for the behaviour of voters, based on the spreading of word of mouth, reproduces well the universal distribution. This finding reveals the existence in the voting process of a general underlying dynamics that does not depend on the specific historical, political and/or ec...

    Full Text Available Background; Children whose verbal communications are not fully developed are the ones at risk for burn injuries. Causes of burn injuries vary among different age groups and scald injuries are the common cause of burn injuries among children. The majority of burns result from contact with thermal agents such as flame, hot surfaces, or hot liquids.Aim: The aim of this study was to determine etiologic factors of the burn injured children Methods: Data were collected for burn injured children treated in Uludag University Medical Hospital Burn Unit between January 2001 – December 2008. Patients’ demographic variables, etiology of burn injury, TBSA(total body surface area, degree of the burn injury, duration of hospitalization was detected from medical records of the hospitalized patients.Results: The mean age of the children was 2.5±1.5 (median=2. Although 4.6 % of burned patients were under one year of age, most of the children (67.8% were between 1-3 years. All of the patients were burned as a result of accident and house environment was the place where the burn incident occurred. Burn injuries occurredmostly during summer (29.9% and spring (28.7%. Scald injuries (75.3% were mostly seen burn injury types all among other burn injuries.Conclusions: Lack of supervision and observation are usually the most common causes of burn injuries in children. Statistical differences were found among age groups according to their burn etiology (p<0.05. An effect of TBSA on patient survival was statistically significant (p<0.000 and also statistically significant results were seen among age groups according to their TBSA’s (p<0.005.

  17. Electric field effects on droplet burning (United States)

    Patyal, Advitya; Kyritsis, Dimitrios; Matalon, Moshe


    The effects of an externally applied electric field are studied on the burning characteristics of a spherically symmetric fuel drop including the structure, mass burning rate and extinction characteristics of the diffusion flame. A reduced three-step chemical kinetic mechanism that reflects the chemi-ionization process for general hydrocarbon fuels has been proposed to capture the production and destruction of ions inside the flame zone. Due to the imposed symmetry, the effect of the ionic wind is simply to modify the pressure field. Our study thus focuses exclusively on the effects of Ohmic heating and kinetic effects on the burning process. Two distinguished limits of weak and strong field are identified, highlighting the relative strength of the internal charge barrier compared to the externally applied field, and numerically simulated. For both limits, significantly different charged species distributions are observed. An increase in the mass burning rate is noticed with increasing field in either limit with negligible change in the flame temperature. Increasing external voltages pushes the flame away from the droplet and causes a strengthening of the flame with a reduction in the extinction Damkhöler number.

  19. Silica Derived from Burned Rice Hulls

    Directory of Open Access Journals (Sweden)

    M.F. de Souza


    Full Text Available Three new processes to obtain silica having high specific surface area from burned pre-treated rice hulls are presented and discussed. These procedures allow for the simultaneous recovery of biomass energy and the production of high quality silica at thermoelectric plants, without the risk of using corrosive substances in the burning process. The first method involves treatment of the hull with hot organic acid solutions before burning, the second with boiling water, both using an autoclave at temperatures close to150 °C, while the third method renders the hull fragile by treating it at 250 °C and reducing it to a fine powder before burning. The first two methods result in white amorphous silica that can show 500 m²/g of specific surface area. The third method, which does not remove the alkaline elements from the hull, produces an amorphous gray carbon-free powder whose specific surface area can be as high as 250 m²/g. An investigation of the specific surface area of the prepared silica indicates the alkaline elements are not mixed with silica in the hulls or combined as insoluble compounds. A comparison is made of these processes and the dissolution of silica by sodium hydroxide solutions is discussed.

    Infection control is very important in burn care units, because burn wound infection is one of the main causes of morbidity and mortality among burn patients. Thus, the appropriate prescription of antibiotics can be helpful, but unreasonable prescription can have detrimental consequences, including greater expenses to patients and community alike. The aim of this study was to determine the effect of antibiotic therapy on the emergence of antibiotic-resistant bacteria. 525 strains of Pseudomonas aeruginosa, Acinetobacter baumannii and Staphylococcus aureus were isolated from 335 hospitalized burn patients. Antibiotic susceptibility tests were performed after identification the strains. The records of patients were audited to find the antibiotic used. The results indicated that P. aeruginosa is the most prevalent Gram-negative bacteria. Further, it showed a relation between abuse of antibiotics and emergence of antibiotic resistance. Control of resistance to antibiotics by appropriate prescription practices not only facilitates prevention of infection caused by multi-drug resistant (MDR) microorganisms, but it can also decrease the cost of treatment.

    Austin, K G; Hansbrough, J F; Dore, C; Noordenbos, J; Buono, M J


    The purpose of this study was to assess the ability of patients with burns on 30 to 40% and 60% or greater of their BSA to thermoregulate their core temperature during exercise in the heat. Two groups (n = 3 in each) of subjects with healed third-degree burns (34.0 +/- 1.4% and 77.7 +/- 12.4%, respectively) and a group of unburned subjects (n = 2) exercised for 1 hour on a cycle ergometer at 75 Watts in an environmental chamber set at 35 degrees C and 60% relative humidity. Subjects were monitored for rectal and skin temperatures, heart rate, whole body sweat rate, skin blood flow, and active sweat gland density (number per cm ) in unburned, burned, and harvested skin. The results demonstrated that patients with burns on 60% or greater BSA did not show an intolerance to moderate exercise in the heat, as evidenced by only a moderate rise in rectal temperature and heart rate. Furthermore, the responses were similar to those of the unburned subjects.

    Knowledge of the circulation of estuaries and adjacent shelf waters has relied on hydrographic measurements, moorings, and local wind observations usually removed from the region of interest. Although these observations are certainly sufficient to identify major characteristics, they lack both spatial resolution and temporal coverage. High resolution synoptic observations are required to identify important coastal processes at smaller scales. Long observation periods are needed to properly sample low-frequency processes that may also be important. The introduction of high-frequency (HF) radar measurements and regional wind models for coastal studies is changing this situation. Here we analyze synoptic, high-resolution surface winds and currents in the Delaware Bay mouth over an eight-month period (October 2007 through May 2008). The surface currents were measured by two high-frequency radars while the surface winds were extracted from a data-assimilating regional wind model. To illustrate the utility of these monitoring tools we focus on two 45-day periods which previously were shown to present contrasting pictures of the circulation. One, the low-outflow period is from 1 October through 14 November 2007; the other is the high-outflow period from 3 March through 16 April 2008. The large-scale characteristics noted by previous workers are clearly corroborated. Specifically the M2 tide dominates the surface currents, and the Delaware Bay outflow plume is clearly evident in the low frequency currents. Several new aspects of the surface circulation were also identified. These include a map of the spatial variability of the M2 tide (validating an earlier model study), persistent low-frequency cross-mouth flow, and a rapid response of the surface currents to a changing wind field. However, strong wind episodes did not persist long enough to set up a sustained Ekman response.

  12. Groundwater exchanges near a channelized versus unmodified stream mouth discharging to a subalpine lake (United States)

    Constantz, J.; Naranjo, R.; Niswonger, R.; Allander, K.; Neilson, B.; Rosenberry, D.; Smith, D.; Rosecrans, C.; Stonestrom, D.


    The terminus of a stream flowing into a larger river, pond, lake, or reservoir is referred to as the stream-mouth reach or simply the stream mouth. The terminus is often characterized by rapidly changing thermal and hydraulic conditions that result in abrupt shifts in surface water/groundwater (sw/gw) exchange patterns, creating the potential for unique biogeochemical processes and ecosystems. Worldwide shoreline development is changing stream-lake interfaces through channelization of stream mouths, i.e., channel straightening and bank stabilization to prevent natural meandering at the shoreline. In the central Sierra Nevada (USA), Lake Tahoe's shoreline has an abundance of both "unmodified" (i.e., not engineered though potentially impacted by broader watershed engineering) and channelized stream mouths. Two representative stream mouths along the lake's north shore, one channelized and one unmodified, were selected to compare and contrast water and heat exchanges. Hydraulic and thermal properties were monitored during separate campaigns in September 2012 and 2013 and sw/gw exchanges were estimated within the stream mouth-shoreline continuum. Heat-flow and water-flow patterns indicated clear differences in the channelized versus the unmodified stream mouth. For the channelized stream mouth, relatively modulated, cool-temperature, low-velocity longitudinal streambed flows discharged offshore beneath warmer buoyant lakeshore water. In contrast, a seasonal barrier bar formed across the unmodified stream mouth, creating higher-velocity subsurface flow paths and higher diurnal temperature variations relative to shoreline water. As a consequence, channelization altered sw/gw exchanges potentially altering biogeochemical processing and ecological systems in and near the stream mouth.

  13. Hand- and Object-Mouthing of Rural Bangladeshi Children 3–18 Months Old

    Full Text Available Children are exposed to environmental contaminants by placing contaminated hands or objects in their mouths. We quantified hand- and object-mouthing frequencies of Bangladeshi children and determined if they differ from those of U.S. children to evaluate the appropriateness of applying U.S. exposure models in other socio-cultural contexts. We conducted a five-hour structured observation of the mouthing behaviors of 148 rural Bangladeshi children aged 3–18 months. We modeled mouthing frequencies using 2-parameter Weibull distributions to compare the modeled medians with those of U.S. children. In Bangladesh the median frequency of hand-mouthing was 37.3 contacts/h for children 3–6 months old, 34.4 contacts/h for children 6–12 months old, and 29.7 contacts/h for children 12–18 months old. The median frequency of object-mouthing was 23.1 contacts/h for children 3–6 months old, 29.6 contacts/h for children 6–12 months old, and 15.2 contacts/h for children 12–18 months old. At all ages both hand- and object-mouthing frequencies were higher than those of U.S. children. Mouthing frequencies were not associated with child location (indoor/outdoor. Using hand- and object-mouthing exposure models from U.S. and other high-income countries might not accurately estimate children’s exposure to environmental contaminants via mouthing in low- and middle-income countries.

  14. Reactive burn models and ignition & growth concept

    Energy Technology Data Exchange (ETDEWEB)

    Menikoff, Ralph S [Los Alamos National Laboratory; Shaw, Milton S [Los Alamos National Laboratory


    Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature). This leads to the Ignition and Growth concept, introduced by Lee and Tarver in 1980, as the basis for reactive burn models. A homogeneized burn rate needs to account for three mesoscale physical effects (i) the density of burnt hot spots, which depends on the lead shock strength; (ii) the growth of the burn fronts triggered by hot spots, which depends on the local deflagration speed; (iii) a geometric factor that accounts for the overlap of deflagration wavelets from adjacent hot spots. These effects can be combined and the burn model defined by specifying the reaction progress variable {lambda}(t) as a function of a dimensionless reaction length {tau}{sub hs}(t)/{ell}{sub hs}, rather than by xpecifying an explicit burn rate. The length scale {ell}{sub hs} is the average distance between hot spots, which is proportional to [N{sub hs}(P{sub s})]{sup -1/3}, where N{sub hs} is the number density of hot spots activated by the lead shock. The reaction length {tau}{sub hs}(t) = {line_integral}{sub 0}{sup t} D(P(t'))dt' is the distance the burn front propagates from a single hot spot, where D is the deflagration speed and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. They have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

  18. A Hydrodynamical Analysis of the Burning of a Neutron Star

    CERN Document Server

    Cho, H T; Speliotopoulos, Achilles D; 10.1016/0370-2693(94)91201-7


    The burning of a neutron star by strange matter is analyzed using relativistic combustion theory with a planar geometry. It is shown that such burning is probably neither slow combustion nor simple detonation. Fast combustion without detonation is possible under certain circumstances, but would involve very efficient heat transfer mechanisms. It is found, however, that the burning is most likely absolutely unstable with no well defined burn front.

  1. Methoxyphenols in smoke from biomass burning

    Energy Technology Data Exchange (ETDEWEB)

    Kjaellstrand, J.


    Wood and other forest plant materials were burned in laboratory experiments with the ambition to simulate the natural burning course in a fireplace or a forest fire. Smoke samples were taken and analysed with respect to methoxyphenols, using gas chromatography and mass spectrometry. Different kinds of bio pellets, intended for residential heating were studied in the same way. The aim of a first study was to establish analytical data to facilitate further research. Thirty-six specific methoxyphenols were identified, and gas chromatographic retention and mass spectrometric data were determined for these. In a subsequent study, the methoxyphenol emissions from the burning of wood and other forest plant materials were investigated. Proportions and concentrations of specific methoxyphenols were determined. Methoxyphenols and anhydrosugars, formed from the decomposition of lignin and cellulose respectively, were the most prominent semi-volatile compounds in the biomass smoke. The methoxyphenol compositions reflected the lignin structures of different plant materials. Softwood smoke contained almost only 2-methoxyphenols, while hardwood smoke contained both 2-methoxyphenols and 2,6-dimethoxyphenols. The methoxyphenols in smoke from pellets, made of sawdust, bark and lignin, reflected the source of biomass. Although smoke from incompletely burned wood contains mainly methoxyphenols and anhydrosugars, there is also a smaller amount of well-known hazardous compounds present. The methoxyphenols are antioxidants. They appear mainly condensed on particles and are presumed to be inhaled together with other smoke components. As antioxidants, phenols interrupt free radical chain reactions and possibly counteract the effect of hazardous smoke components. Health hazards of small-scale wood burning should be re-evaluated considering antioxidant effects of the methoxyphenols.

    Conclusions: Burn injuries are common in our settings, a more reason for all to know the immediate intervention to give to victims of such accidents. The kind of first aid administered to burns victims possibly affects the burns management outcome. Thus, the earlier the right intervention implemented, the lesser the complications.

  5. Sexuality after burn in Brazil: survey of burn health-care workers. (United States)

    Piccolo, Monica Sarto; Daher, Ricardo Piccolo; Gragnani, Alfredo; Ferreira, Lydia Masako


    Patients who survive a major burn must live with emotional and physical sequela. In a literature review, we found that sexuality concerns of burn victims are rarely a focus of therapy. After suggestions from Rimmer et al. [12], using their questionnaire translated into Portuguese, we held a survey of burn-care professionals at the VII Brazilian Burn Congress. More than 120 practitioners from 41 centres, aged in average 41.2 years (1 standard deviation 10.96), completed the survey. A proportion of 63.7% were female, and 58.1% were Caucasians; 37.1% were physicians, 20.9% nurse practitioners and 16.9 were occupational therapists/physical therapists (OTs/PT)s. Psychologists made up 3.2%. Only 28% of the respondents felt comfortable in initiating a conversation about sexual intimacy with their patients. The vast majority believed it should be done by the psychologist. Only 38% felt their burn centre did an adequate job in that area. When compared with a study of our country's general population, we find similar results indicating that intimacy, sexuality and sexual intercourse are considered most important in a relationship. There is a significant lack of literature in sexuality after burn; most likely meaning it is ignored by most centres. There is a need for other similar surveys to be performed, as well as a collective consciousness of the need for discussions about sexuality with patients and their partners, providing counselling and treatment, when need.

  6. New treatment strategies to reduce burn wound progression

    Directory of Open Access Journals (Sweden)

    Schmauss, Daniel


    Full Text Available [english] Background: After a burn injury certain superficial partial-thickness burn wounds spontaneously progress into deep partial-thickness or full-thickness burn wounds. This poorly understood phenomenon is called burn wound progression. The aim of this study was to investigate whether treatment strategies using warm water (preservation of microcirculation on the one side and erythropoietin (EPO (molecule with anti-inflammatory, anti-apoptotic, vasodilatory and neoangiogenic properties can prevent, delay and/or reduce secondary burn wound progression in a rat model.Methods: We used a burn comb model in 63 rats, creating eight rectangular contact burns (2x1 cm each intercalated by unburned zones (2x0.5 cm prone to burn wound progression. In a first experimental set we treated burn wounds with locally applied warm (37°C or cold (17°C water for 20 minutes.In a second experimental set, animals were treated systemically with EPO at two different dosages of 500 and 2,500 IU/kg bodyweight (bw and initiated at 2 different time-points (45 minutes vs. 6 hours after burn injury. Evaluation of microcirculatory perfusion, interspace necrosis and burn depth was performed using respectively laser Doppler flowmetry, planimetry and histology. For statistical analysis the two-way ANOVA-test followed by an adequate post-hoc test (Bonferroni were used. Results: In untreated control animals a conversion from superficial to full-thickness burns was observed within 24 hours. Warm and cold water treatment significantly delayed burn depth progression, nevertheless after 4 days, burn depth was similar in all three groups. Warm water significantly reduced interspace necrosis compared to untreated controls and cold water with a significantly improved perfusion in the warm water group. Surface extension and particularly burn depth progression were significantly decreased by EPO only if administered at a dosage of bw and initiated 45 minutes after burn injury. EPO

  10. A clinico-epidemiological study of rescuer burns. (United States)

    Basra, Baljeet Kumar; Suri, Manav P; Patil, Nilesh; Atha, Ravish; Patel, Natvar; Sachde, Jayesh P; Shaikh, M F


    Rescuer burn is a relatively newer terminology introduced to define the burns sustained by a person attempting to rescue a primary burn victim. Few studies have been published thus far on this peculiar type of burns. Due to the general neglect of the rescuer burns victim and discontinuation of treatment in most cases, once the primary victim dies, the rescuer often ends up in badly infected wounds and has a delayed return to work. A prospective study was conducted at the B J Medical College and Civil Hospital, Ahmedabad from January 2009 to December 2012 on the rescuer burns patients treated in its burns and plastic surgery department. 3074 patients of burns received treatment during the period of study. Of these, 48 patients gave the history of sustaining burns while trying to rescue a burns victim. Male to female ratio of rescuers was approximately 7:1. It was significantly higher as compared to the ratio of 1:0.8 of females to male burn victims observed at our centre (p≤0.01). Average age of the rescuers was higher in males as compared to females but the difference was not significant (p≥0.05). Of the 45 cases of female primary burns victims, male rescuer was husband of the primary victim in 41/45 cases (91.1%), mother was rescuer in three cases (6.6% cases) and sister was rescuer in one case. Though multiple people came to rescue a burns victim, in all cases, it was seen that it was the first rescuer who sustained burns himself or herself. None of the rescuers had any knowledge of the techniques and precautions to be taken while performing a rescue operation irrespective of their education status, indirectly pointing to the lack of any teaching on burns rescue in the school education curriculum.

  11. Detection algorithm for glass bottle mouth defect by continuous wavelet transform based on machine vision (United States)

    Qian, Jinfang; Zhang, Changjiang


    An efficient algorithm based on continuous wavelet transform combining with pre-knowledge, which can be used to detect the defect of glass bottle mouth, is proposed. Firstly, under the condition of ball integral light source, a perfect glass bottle mouth image is obtained by Japanese Computar camera through the interface of IEEE-1394b. A single threshold method based on gray level histogram is used to obtain the binary image of the glass bottle mouth. In order to efficiently suppress noise, moving average filter is employed to smooth the histogram of original glass bottle mouth image. And then continuous wavelet transform is done to accurately determine the segmentation threshold. Mathematical morphology operations are used to get normal binary bottle mouth mask. A glass bottle to be detected is moving to the detection zone by conveyor belt. Both bottle mouth image and binary image are obtained by above method. The binary image is multiplied with normal bottle mask and a region of interest is got. Four parameters (number of connected regions, coordinate of centroid position, diameter of inner cycle, and area of annular region) can be computed based on the region of interest. Glass bottle mouth detection rules are designed by above four parameters so as to accurately detect and identify the defect conditions of glass bottle. Finally, the glass bottles of Coca-Cola Company are used to verify the proposed algorithm. The experimental results show that the proposed algorithm can accurately detect the defect conditions of the glass bottles and have 98% detecting accuracy.

  12. Simulated circulations off the Changjiang (Yangtze) River mouth in spring and autumn

    Institute of Scientific and Technical Information of China (English)

    朱建荣; 戚定满; 肖成猷


    The circulations off the Changjiang mouth in May and November were simulated by a three dimension numerical model with monthly averaged parameters of dynamic factors in this paper. The area covers the East China Sea (ECS), Yellow Sea and Bohai Sea. Simulated results show that the circulation off the Changjiang mouth in spring and autumn is mainly the Changjiang runoff and Taiwan Warm Current (TWC). The Changjiang discharge is much larger in May than in November, and the wind is westward in May, and southward in November off the Changjiang mouth. The runoff in May branches in three parts, one eastward flows, the other two flow northward and southward along the Subei and Zhejiang coast respectively. The Changjiang diluted water expands eastward off the mouth, and forms a strong salinity front near the mouth. Surface circulation in autumn is similar to that in winter, the runoff southward flows along the coast, and the northward flowing TWC becomes weaker compared to that in spring and summer. The bottom circulations in May and November are mainly the runoffnear the mouth and the TWC offthe mouth, and the runoff and TWC are greater in May than in November.

  13. Evaluation of oxygen saturation by pulse-oximetry in mouth breathing patients. (United States)

    Niaki, Esfandiar Akhavan; Chalipa, Javad; Taghipoor, Elahe


    Mouth breathing might not always result in hypoxia, but can contribute to it. The aim of the present study was to determine the effect of mouth breathing on hypoxia. Based on a pilot study, 323 patients with mouth breathing were selected. Assessment of mouth breathing was based on clinical examination and questionnaires filled out by patients and their companions. The patients were also examined for further oral findings that could be attributable to mouth breathing. Oxygen saturation of each case was measured by means of a pulse oximetry device. The level of 95% saturation was set as the limit, under which the patient was considered hypoxemic. Acquired data was analyzed for descriptive data and frequency and also by means of the Chi-square and Spearman's correlation coefficient tests. 34.6% of the cases had normal O2 saturation. 65.4% of cases were hypoxemic (saturation level was below 95% in 42.8% and 95% in 22.6%). Most of the mouth breathing patients were male who were also more hypoxemic. A weak inverse relationship existed between the age of the patients and Oxygen saturation. Deep palatal vaults (29.4%) and gingival hyperplasia (29.2%) were the most frequent intraoral findings. Concerning the effects of hypoxia on body systems, the use of pulse oximetry in suspected mouth breathing patients could be recommended in routine oral and dental examinations.

  15. Bilingualism modulates infants' selective attention to the mouth of a talking face. (United States)

    Pons, Ferran; Bosch, Laura; Lewkowicz, David J


    Infants growing up in bilingual environments succeed at learning two languages. What adaptive processes enable them to master the more complex nature of bilingual input? One possibility is that bilingual infants take greater advantage of the redundancy of the audiovisual speech that they usually experience during social interactions. Thus, we investigated whether bilingual infants' need to keep languages apart increases their attention to the mouth as a source of redundant and reliable speech cues. We measured selective attention to talking faces in 4-, 8-, and 12-month-old Catalan and Spanish monolingual and bilingual infants. Monolinguals looked more at the eyes than the mouth at 4 months and more at the mouth than the eyes at 8 months in response to both native and nonnative speech, but they looked more at the mouth than the eyes at 12 months only in response to nonnative speech. In contrast, bilinguals looked equally at the eyes and mouth at 4 months, more at the mouth than the eyes at 8 months, and more at the mouth than the eyes at 12 months, and these patterns of responses were found for both native and nonnative speech at all ages. Thus, to support their dual-language acquisition processes, bilingual infants exploit the greater perceptual salience of redundant audiovisual speech cues at an earlier age and for a longer time than monolingual infants.

  16. Speech-language pathology findings in patients with mouth breathing: multidisciplinary diagnosis according to etiology. (United States)

    Junqueira, Patrícia; Marchesan, Irene Queiroz; de Oliveira, Luciana Regina; Ciccone, Emílio; Haddad, Leonardo; Rizzo, Maria Cândida


    The purpose of this study was to identify and compare the results of the findings from speech-language pathology evaluations for orofacial function including tongue and lip rest postures, tonus, articulation and speech, voice and language, chewing, and deglutition in children who had a history of mouth breathing. The diagnoses for mouth breathing included: allergic rhinitis, adenoidal hypertrophy, allergic rhinitis with adenoidal hypertrophy; and/or functional mouth breathing. This study was conducted with on 414 subjects of both genders, from 2 to 16-years old. A team consisting of 3 speech-language pathologists, 1 pediatrician, 1 allergist, and 1 otolaryngologist, evaluated the patients. Multidisciplinary clinical examinations were carried out (complete blood counting, X-rays, nasofibroscopy, audiometry). The two most commonly found etiologies were allergic rhinitis, followed by functional mouth breathing. Of the 414 patients in the study, 346 received a speech-language pathology evaluation. The most prevalent finding in this group of 346 subjects was the presence of orofacial myofunctional disorders. The most frequently orofacial myofunctional disorder identified in these subjects who also presented mouth breathing included: habitual open lips rest posture, low and forward tongue rest posture and lack of adequate muscle tone. There were also no statistically significant relationships identified between etiology and speech-language diagnosis. Therefore, the specific type of etiology of mouth breathing does not appear to contribute to the presence, type, or number of speech-language findings which may result from mouth breathing behavior.

  17. Using online blogs to explore positive outcomes after burn injuries. (United States)

    Garbett, Kirsty; Harcourt, Diana; Buchanan, Heather


    This study uses blog analysis, a new and novel technique, to explore the positive outcomes experienced by burn survivors. This study examined 10 burn survivor blogs to offer a unique, longitudinal insight into burn survivor recovery. Using thematic analysis, three themes emerged: shift in self-perception, enhanced relationships and a change in life outlook. Many of these themes contained stories and experiences unique to a traumatic burn injury, suggesting that standardised trauma scales are not effectively measuring the impact of a burn in this population. Reflections on blog analysis are discussed, along with a recommendation that health researchers utilise the vast amount of data available from online blogs.

  18. Importance of proper initial treatment of moderate and major burns

    Directory of Open Access Journals (Sweden)

    Vulović Dejan


    Full Text Available Background/Aim. Burns are common injuries with frequency depending on human factors, development of protection, industry and traffic, eventual wars. Organized treatment of major burn injuries has tremendous medical, social and economic importance. The aim of this study was to analyze initial treatment of major and moderate burns, to compare it with the current recommendations and to signify the importance of organized management of burns. Methods. In a prospective study 547 adult patients with major burns were analyzed, covering a period of eight years, with the emphasis on the initial hospital admission and emergency care for burns greater than 10% of total body surface area (TBSA. Results. In the different groups of major burns, the percentage of hospital admission was: 81.5 in burns greater than 10% TBSA, 37.7 in burns of the functional areas, 54.5 in the III degree burns, 81.6 in electrical burns, 55.9 in chemical burns, 61.9 in inhalation injury, 41.0 in burns in patients with the greater risk and 100 in burns with a concomitant trauma. In the group of 145 patients with burns greater than 10% TBSA, intravenous fluids were given in 87 patients, analgesics in 45, corticosteroids in 29, antibiotics in 23 and oxygen administration in 14. In the same group, wound irrigation was done in 14.4%, removing of the clothing and shoes in 29.6%, elevation of the legs in 8.9% and prevention of hypothermia in 7.6% of the victims. There were no initial estimations of burn extent (percentage of a burn, notes about the patient and injury and tetanus immunizations. Conclusion. Based on these findings, it is concluded that there should be much more initial hospital admissions of major burns, and also, necessary steps in the emergency care of burns greater than 10% TBSA should be taken more frequently. On the other side, unnecessary or wrong steps should be avoided in the initial burn treatment.

    Water and sediment qualities are studied by analyzing samples taking from the mouths of the Haihe, Duliujian, New Ziya and Beipai rivers in the Haihe river basin in north China in 2005 and 2001, in order to find the changes of water and sediment pollutions. The concentrations of heavy metals, arsenic, total nitrogen (TN) and total phosphorus (TP) are analyzed and results have been compared for the two times. The in-situ measurement for Dissolved Oxygen (DO) and Sediment Oxygen Demand (SOD) rates were carried at the Haihe and Duliujian river mouths in 2006. The results show that the waters of the 4 river mouths are still seriously polluted, though much improved in the case of the Haihe and Duliujian rivers. The main pollutants are TP and TN in the New Ziya and Beipai rivers and mercury (Hg) at all 4 river mouths. Compared with those in 2001, the concentrations of almost all metals and arsenic in the 4 river mouths have decreased. Water quality at Haihe and Duliujian shows an improving trend, while the water quality at Beipai is similar to that of 2001. In contrast, water at the New Ziya river mouth is more severely polluted. The sediments in the 4 river mouths are not seriously polluted by heavy metals but are polluted by nitrogen and phosphorus. Most of the pollutant contents in the sediments show little change between 2001 and 2005. The in-situ DO and SOD measurement shows that the waters at the Haihe river mouth is in the state of oxygen depletion, and SOD is important consumer of DO at the river mouths. The overall analysis shows that increasing water pollution and eutrophication in waters far from cities are ongoing causes of concern.

    van Gelderen, Laurens; Farahani, Hamed Farmahini; Rangwala, Ali S.;

    In order to improve the validity of small scale crude oil burning experiments, which seem to underestimate the burning efficiency obtained in larger scales, the gasification mechanism of crude oil was studied. Gasification models obtained from literature were used to make a set of predictions...... for relevant burning related parameters which were then compared to experimental results. These parameters, the surface temperature, mass loss rate, flame height and residue composition, were studied for three hydrocarbon liquids (n-octane, dodecane and hexadecane) and two crude oils (DUC and REBCO). Based...... on the models-experiments comparison, it was suggested that crude oil burns according to a distillation-like mechanism, with the light components burning off first, followed by increasingly heavier components as the burning progresses. Thus, in order for the crude oil to burn near 100%, the surface temperature...

  1. Do burns increase the severity of terror injuries? (United States)

    Peleg, Kobi; Liran, Alon; Tessone, Ariel; Givon, Adi; Orenstein, Arie; Haik, Josef


    The use of explosives and suicide bombings has become more frequent since October 2000. This change in the nature of terror attacks has marked a new era in the Israeli-Palestinian conflict. We previously reported that the incidence of thermal injuries has since risen. However, the rise in the incidence of burns among victims of terror was proportionate to the rise in the incidence of burns among all trauma victims. This paper presents data from the Israeli National Trauma Registry during the years 1997--2003, to compare the severity of injuries and outcome (mortality rates) in terror victims with and without burn injuries. We also compare the severity of injuries and outcome (mortality rates) for patients with terror-attack related burns to non terror-attack related burns during the same period. Data was obtained from the Israeli National Trauma Registry for all patients admitted to 8 to 10 hospitals in Israel between 1997 and 2003. We analyzed and compared demographic and clinical characteristics of 219 terror-related burn patients (terror/burn), 2228 terror patients with no associated burns (Terror/no-burn) and 6546 non terror related burn patients (burn/no-terror). Severity of injuries was measured using the injury severity score, and burn severity by total body surface percentage indices. Admission rates to Intensive Care Units (ICU) and total length of hospitalization were also used to measure severity of injuries. In-hospital mortality rates were used to indicate outcome. Of burn/terror patients, 87.2% suffered other accompanying injuries, compared with 10.4% of burn/no-terror patients. Of burn/terror patients, 49.8% were admitted to ICU compared with only 11.9% of burn/no-terror patients and 23.8% of no-burn/terror patients. Mean length of hospital stay was 18.5 days for the terror/burn group compared with 11.1 days for the burn/no-terror group and 9.5 days for the terror/no-burn group. Burn/terror patients had a significantly higher injury severity score

    Full Text Available Despite the frequency and severity of burns in Low Income Countries, including many in Africa, there is a paucity of research and funding for these populations to aid in prevention, treatment and recovery of burn patients. The objectives of this paper are four-fold. First, by addressing the pathophysiology of burns the reader may strengthen understanding of the clinical progression of burns. Second, through describing proper assessment of burn patients one will learn how to decide if patients can be discharged, admitted or transferred to burn centre. Third, the inclusion of treatments solidifies the steps necessary to manage a patient in a hospital setting. Lastly, the overall goal of the paper, is to raise awareness that more research, publication and funding is required to create a better understanding of burns in Africa and why they continue to be devastating social and economic burdens.

    Kanehira, Takashi; Takehara, Junji; Takahashi, Dairo; Honda, Okahito; Morita, Manabu


    The prevalence of oral malodor and association of habitual mouth breathing with oral malodor were investigated in children residing in rural areas. One hundred and nineteen children participated in this study. A sulfide monitor and organoleptic method were used to evaluate oral malodor. About 8% of children had a sulfide level in mouth air above the socially acceptable limit (75 ppb). Habitual mouth breathing was a factor contributing to oral malodor. Oral malodor was not significantly correlated with plaque index, history of caries or frequency of toothbrushing.

  5. Biomass Burning Emissions from Fire Remote Sensing (United States)

    Ichoku, Charles


    Knowledge of the emission source strengths of different (particulate and gaseous) atmospheric constituents is one of the principal ingredients upon which the modeling and forecasting of their distribution and impacts depend. Biomass burning emissions are complex and difficult to quantify. However, satellite remote sensing is providing us tremendous opportunities to measure the fire radiative energy (FRE) release rate or power (FRP), which has a direct relationship with the rates of biomass consumption and emissions of major smoke constituents. In this presentation, we will show how the satellite measurement of FRP is facilitating the quantitative characterization of biomass burning and smoke emission rates, and the implications of this unique capability for improving our understanding of smoke impacts on air quality, weather, and climate. We will also discuss some of the challenges and uncertainties associated with satellite measurement of FRP and how they are being addressed.

    Under the DOE Deep Burn program TRISO fuel is being investigated as a fuel form for consuming plutonium and minor actinides, and for greater efficiency in uranium utilization. The result will thus be to drive TRISO particulate fuel to very high burn-ups. In the current effort the various phenomena in the TRISO particle are being modeled using a variety of techniques. The chemical behavior is being treated utilizing thermochemical analysis to identify phase formation/transformation and chemical activities in the particle, including kernel migration. Density functional theory is being used to understand fission product diffusion within the plutonia oxide kernel, the fission product's attack on the SiC coating layer, as well as fission product diffusion through an alternative coating layer, ZrC. Finally, a multiscale approach is being used to understand thermal transport, including the effect of radiation damage induced defects, in a model SiC material.

Conclusion: respect, understanding and care from the health team were fundamental for the adaptation and the confrontation demanded by the consequent suffering of the event.

  8. Probing thermonuclear burning on accreting neutron stars


    Keek, L.


    Neutron stars are the most compact stars that can be directly observed, which makes them ideal laboratories to study physics at extreme densities. Neutron stars in low-mass X-ray binaries accrete hydrogen and helium from a lower-mass companion star through Roche lobe overflow. This matter undergoes thermonuclear burning in the neutron star envelope, creating carbon and heavier elements. The fusion process may proceed in an unstable manner, resulting in a thermonuclear runaway. Within one seco...

    Linden, Katharina; Stewart, Ian J; Kreyer, Stefan F X; Scaravilli, Vittorio; Cannon, Jeremy W; Cancio, Leopoldo C; Batchinsky, Andriy I; Chung, Kevin K


    A prolonged and fulminant inflammatory state, with high levels of pro- and anti-inflammatory mediators, is seen after extensive thermal injury. Blood purification techniques including plasma exchange, continuous venovenous hemofiltration, and adsorbing membranes have the potential to modulate this response, thereby improving outcomes. This article describes the scientific rationale behind blood purification in burns and offers a review of literature regarding its potential application in this patient cohort.

    On the morning of June 9, 2009, an explosion occurred at a manufacturing plant in Garner, North Carolina. By the end of the day, 68 injured patients had been evaluated at the 3 Level I trauma centers and 3 community hospitals in the Raleigh/Durham metro area (3 people who were buried in the structural collapse died at the scene). Approximately 300 employees were present at the time of the explosion, when natural gas being vented during the repair of a hot water heater ignited. The concussion from the explosion led to structural failure in multiple locations and breached additional natural gas, electrical, and ammonia lines that ran overhead in the 1-story concrete industrial plant. Intent is the major difference between this type of accident and a terrorist using an incendiary device to terrorize a targeted population. But while this disaster lacked intent, the response, rescue, and outcomes were improved as a result of bioterrorism preparedness. This article discusses how bioterrorism hospital preparedness planning, with an all-hazards approach, became the basis for coordinated burn surge disaster preparedness. This real-world disaster challenged a variety of systems, hospitals, and healthcare providers to work efficiently and effectively to manage multiple survivors. Burn-injured patients served as a focus for this work. We describe the response, rescue, and resuscitation provided by first responders and first receivers as well as efforts made to develop burn care capabilities and surge capacity.

    The national U.S. Burning Plasma Organization (USBPO) was formed to provide an umbrella structure in the U.S. fusion science research community. Its main purpose is the coordination of research activities in the U.S. program relevant to burning plasma science and preparations for participation in the international ITER experiment. This grant provided support for the continuing development and operations of the USBPO in its first years of existence. A central feature of the USBPO is the requirement for broad community participation in and governance of this effort. We concentrated on five central areas of activity of the USBPO during this grant period. These included: 1) activities of the Director and support staff in continuing management and development of the USBPO activity; 2) activation of the advisory Council; 3) formation and initial research activities of the research community Topical Groups; 4) formation of Task Groups to perform specific burning plasma related research and development activities; 5) integration of the USBPO community with the ITER Project Office as needed to support ITER development in the U.S.

  14. A Model For The Burning of Teflon (United States)

    Waller, Jess M.; Wilson, D. Bruce; Beeson, Harold D.; Fries, Joseph (Technical Monitor)


    Teflon has been identified as suitable material for use in oxygen-enriched atmospheres because of its low specific enthalpy of combustion that is, less than 1500 cal/gram. However, once ignited, Teflon burns in a heterogeneous reaction until total consumption or depletion of oxygen occurs. A model is developed for the burning of Teflon in pure, high-pressure oxygen, 3.4 to 68.9 MPa. The Teflon polymer chain dissociates via monomer units due to pyrolysis. These monomer units diffuse to the surface due to free convection. The model consists of coupled mass and energy balances for the polymer and an energy balance for the free convection of product gases. The model is used to obtain appropriate kinetic parameters for the dissociation and surface reactions. The model is validated against experimental measurements of Teflon discs supported on aluminum rods (2216) at oxygen pressures of 3.4, 6.8, 34.4, and 68.9 MPa. The model simulates the temperature distribution in the product gases above burning Teflon.

  15. Opioid-induced hyperalgesia and burn pain. (United States)

    Holtman, Joseph R; Jellish, W Scott


    The treatment of pain produced during the management of burn injury has been an ongoing problem for physicians caring for these patients. The main therapeutic option for analgesia has been the repeated and prolonged use of opioids. The adverse effects of opioids are well known but the long term use of opioids which produces tolerance with accompanying dose escalation and dependence is most problematic. Another potentially important consequence of opioid exposure that sometimes masks as tolerance is that of opioid induced hyperalgesia. This syndrome is manifest as enhanced pain, sensitivity and loss of analgesic efficacy in patients treated with opioids who actually become sensitized to painful stimuli. This article focuses on the treatment of burn pain and how current analgesic therapies with opioids may cause hyperalgesia and affect the adequacy of treatment for burn pain. This article also provides possible modalities to help therapeutically manage these patients and considers future analgesic strategies which may help to improve pain management in this complicated patient population.

  16. Current concepts on burn wound conversion-A review of recent advances in understanding the secondary progressions of burns. (United States)

    Salibian, Ara A; Rosario, Angelica Tan Del; Severo, Lucio De Almeida Moura; Nguyen, Long; Banyard, Derek A; Toranto, Jason D; Evans, Gregory R D; Widgerow, Alan D


    Burn wound conversion describes the process by which superficial partial thickness burns convert into deeper burns necessitating surgical intervention. Fully understanding and thus controlling this phenomenon continues to defy burn surgeons. However, potentially guiding burn wound progression so as to obviate the need for surgery while still bringing about healing with limited scarring is the major unmet challenge. Comprehending the pathophysiologic background contributing to deeper progression of these burns is an essential prerequisite to planning any intervention. In this study, a review of articles examining burn wound progression over the last five years was conducted to analyze trends in recent burn progression research, determine changes in understanding of the pathogenesis of burn conversion, and subsequently examine the direction for future research in developing therapies. The majority of recent research focuses on applying therapies from other disease processes to common underlying pathogenic mechanisms in burn conversion. While ischemia, inflammation, and free oxygen radicals continue to demonstrate a critical role in secondary necrosis, novel mechanisms such as autophagy have also been shown to contribute affect significantly burn progression significantly. Further research will have to determine whether multiple mechanisms should be targeted when developing clinical therapies.

  17. Physical functional outcome assessment of patients with major burns admitted to a UK Burn Intensive Care Unit. (United States)

    Smailes, Sarah T; Engelsman, Kayleen; Dziewulski, Peter


    Determining the discharge outcome of burn patients can be challenging and therefore a validated objective measure of functional independence would assist with this process. We developed the Functional Assessment for Burns (FAB) score to measure burn patients' functional independence. FAB scores were taken on discharge from ICU (FAB 1) and on discharge from inpatient burn care (FAB 2) in 56 patients meeting the American Burn Association criteria for major burn. We retrospectively analysed prospectively collected data to measure the progress of patients' physical functional outcomes and to evaluate the predictive validity of the FAB score for discharge outcome. Mean age was 38.6 years and median burn size 35%. Significant improvements were made in the physical functional outcomes between FAB 1 and FAB 2 scores (ppatients were discharged home, 8 of these with social care. 8 patients were transferred to another hospital for further inpatient rehabilitation. FAB 1 score (≤ 9) is strongly associated with discharge outcome (pburn patients.

  18. Hand, foot and mouth disease--outbreak in Romania? (United States)

    Chiriac, Anca; Foia, Liliana; Chiriac, Anca; Nanescu, Sonia; Filip, Florina; Solovan, C; Gorduza, E V


    Hand, foot and mouth disease (HFMD) is a viral illness usually occurring during the summer months in children younger than 5 years of age. In the North-East area of Romania the incidence is usually low, each dermatologist reporting 1-2 cases or even less per year. The diagnosis is usually based on the characteristic clinical aspect: vesicles and papules on the hands and feet and superficial oral ulcers. HFMD is typically a benign and self-limiting disease that resolves in approximately 7 days; in Asia there have been few reported severe cases that developed neurological complications and even death, while in certain areas of China this disease is a more and more serious public health problem. In the summer of 2012 in North-East Romania numerous cases of disease have been reported, some with atypical clinical manifestations and most of them with mild or moderate forms of disease. The present article is a discussion on one of these cases. The diagnosis was made based on lesions location and clinical appearance. An outbreak of HFMD should be confirmed by virology tests.

  19. Word of Mouth Propagation in Online Social Networks

    Directory of Open Access Journals (Sweden)

    Xiaoting Han


    Full Text Available Online social networks (OSNs are becoming an important propagation platform for Word of mouth (WOM. Therefore, it is of great significance to study the propagation of WOM in OSNs. A WOM propagation model named N-P-N is proposed in this paper, and some simulation experiments are carried out to investigate the mechanism of WOM propagation. From the sensitivity analysis of degree of initial information source node, it can be seen that the degree of initial information source node determines the scope and speed of the propagation of WOM in OSNs in some extent. Then the sensitivity analysis of number of initial information source nodes shows that the initial source nodes are crucial for controlling the propagation of negative information in OSNs. Moreover, from the user behavior respect, it is found that different user behavior in OSNs causes different propagation results, the more users who are willing to diffuse WOM, the more scope WOM can propagate and the faster the information diffuses. Findings in this paper are helpful for enterprises to form an effective WOM.

    Full Text Available Consumption may be defined as the supply of people’s desire and needs in return for a certain cost. The meaning that consumption bears has changed over the years passed. Not only did consumption remain as an activity performed so that people could meet their biological needs, but it turned out to be something carried out by those seeking for a social status within the society, as well. Veblen argued that consumption has a conspicuous aspect and coined the term “conspicuous consumption” into the litera- ture. Consumers performing conspicuous consumption are able to benefit from social status, prestige and reputation which derive from consuming a product or a service by talking about them with the people around. This study aims to scrutinize the impact of word of mouth marketing on conspicuous consump- tion. The samples in the study are individuals over 18 living in Istanbul. In this context, 407 consumers are involved in the study. Obtained data have been analyzed by using SPSS Version 21 (Statistical Packages for Social Science.

  1. Foot and mouth disease: a look from the wild side. (United States)

    Weaver, Genevieve V; Domenech, Joseph; Thiermann, Alex R; Karesh, William B


    We review the literature and discuss control options regarding foot and mouth disease (FMD) in wildlife around the world. There are more than 100 species of wild, feral, laboratory, or domesticated animals that have been infected naturally or experimentally with FMD virus. Apart from the African buffalo (Syncerus caffer) in sub-Saharan Africa, wildlife has not been demonstrated to play a significant role in the maintenance of FMD. More often, wildlife are passively infected when outbreaks of FMD occur in domestic livestock, and, in some wild ungulates, infection results in severe disease. Efforts to control FMD in wildlife may not be successful when the disease is endemic in livestock and may cause more harm to wildlife, human livelihoods, and domestic animals. Currently in sub-Saharan Africa, the complete eradication of FMD on a subcontinental scale in the near term is not possible, given the presence of FMD-infected African buffalo and the existence of weak veterinary infrastructures in some FMD-endemic countries. Therefore efforts to control the disease should be aimed at improved vaccines and improved use of vaccines, improved livestock management practices, and utilization of programs that can help in disease control such as the FMD Progressive Control Program and regulatory frameworks that facilitate trade such zonation, compartmentalization, and commodity-based trade. Though not meeting the definition of wildlife used in this review, feral domestic animals warrant a special concern with regard to FMD control.

    Background Mass burn casualties are always a great challenge to a medical team because a large number of seriously injured patients were sent in within a short time. Usually a high mortality is impending. Experiences gained from successful treatment of the victims may be useful in guiding the care of mass casualties in an armed conflict.Methods Thirty-five burn victims in a single batch, being transferred nonstop by air and highway from a distant province,were admitted 48 hours post-injury. All patients were male with a mean age of (22.4±8.7) years. The burn extent ranged from 4% to 75% ((13.6±12.9)%) total body surface area. Among them, thirty-two patients were complicated by moderate and severe inhalation injury, and tracheostomy had been performed in 15 patients. Decompression incisions of burn eschar on extremities were done in 17 cases before transportation. All the thirty-five patients arrived at the destination smoothly via 4-hour airlift and road transportation. Among them, twenty-five patients were in critical condition.Results These thirty-five patients were evacuated 6 hours from the scene of the injury, and they were transferred to a local hospital for primary emergency care. The patients were in very poor condition when admitted to our hospital because of the severe injury with delayed and inadequate treatment. Examination of these patients at admission showed that one patient was suffering from sepsis and multiple organ dysfunction syndrome. Dysfunction of the heart, lung, liver,kidney, and coagulation were all found in the patients. Forty-eight operations were performed in the 23 patients during one month together with comprehensive treatment, and the function of various organs was ameliorated after appropriate treatment. All the 35 patients survived.Conclusions A well-organized team consisting of several cooperative groups with specified duties is very important. As a whole, the treatment protocol should be individualized, basing on the extent of

  3. Static reconstruction of malar region in facial paralysis: a new alternative technique for plasty of symmetric mouth appearance. (United States)

    Yoshimoto, Shinya; Sato, Nobuhiro; Kuroki, Tomoaki; Rikihisa, Naoaki; Ichinose, Masaharu


    Static suspension using fascia lata graft is used as a reconstructive procedure against drooping of the mouth corner for treating longstanding facial paralysis. Although it achieves symmetry at rest, movement of the mouth corner at mouth opening is restricted to some extent because it is fixed with fascia lata to the immovable temporal fascia, the parotid fascia, or bones. This was overcome by suspending the mouth corner to the mandibular coronoid process with fascia lata, which enabled a shift of the mouth corner with mouth opening and closure. The nine patients discussed in this study were operated on since 1994 for longstanding facial paralysis and followed-up for over 1.5 years. As in conventional static suspension, the fascia lata was harvested and split into two bands. Next, one semi-oval fascial loop was inserted around the paralysed part of the mouth and tied with another fascial band at the mouth corner, which was looped to the mandibular coronoid process. The suspended fascia lata graft was relaxed with anteroinferior movement of the coronoid process at mouth opening, enabling the mouth corner to shift inferiorly. The mouth corner returned to its original position at mouth closure, and the nasolabial fold deepened during mastication. No limitation in mouth opening was observed. Suspension of the mouth corner to the mandibular coronoid process provided a dynamic element, thereby restoring a near-normal shift. The procedure is considered as an alternative for reconstructing the malar region of patients with facial paralysis and in whom dynamic reconstruction is not indicated.

This question has important implications for service-based industries like universities. Results suggest that positive word of mouth intention is influenced by psychographic characteristics. Generation Y's positive word of mouth antecedents were: high collectivism, high uncertainty avoidance, and high power distance. Generation X's had only one antecedent, high collectivism. This paper concludes by outlining the areas for future research of Generation Y and the implication of this research for university leaders tasked with enhancing positive word of mouth in current students and alumni.

    Data taken in two large scale ocean observations in China in summer 1959 and 1982 were used to analyze the residual current off the Changjiang (Yangtze) River mouth. The currents at surface off the mouth in July 1959 and 1982 flow northeastward and eastward due to the river discharge, the current speed was larger in1982 than in 1959. All the bottom currents flow landward due to baroclinic effect. The surface current was controlled by the river runoff and the Taiwan Warm Current (TWC). A return current at surface off the mouth was observed in September 1959. In general, the bottom currents were controlled by the TWC in most study area in addition to the runoff near the mouth. Although driven by 3-D model with the monthly averaged forces (river discharge, wind stress, baroclinic effect, open boundary water volume flux and tidal mixing) in August, the simulated circulations were basically consistent with the observed ones with episodic time manner.

  9. Amish Culture and Their Utilization of Burns and Wounds Ointment for the Treatment of Burns. (United States)

    Trinkle, Krystal Melich


    As indicated in the 2010 United States Religion Census, there are approximately 251,000 Amish people in the United States and Ontario. This census also demonstrated that a new Amish community is founded on average about every three-and-a-half weeks, suggesting that this religious culture is the fastest-growing religion throughout the United States. Because of the rapid growth of the Amish population, it is essential for health care workers to understand their background, cultural, and health care beliefs, especially in the treatment of burns. The purpose of this article is to examine the Amish background, cultural, and health care beliefs, specifically the utilization of burns and wounds ointment and burdock leaves in the treatment of burns.

    Lim, Ji Hwan; Lee, Sang Hyup; Yoon, Woong Sup [Yonsei University, Seoul (Korea, Republic of)


    Ignition and the burning of air-born single aluminum and magnesium particles are experimentally investigated. Particles of 30 to 106 μm-diameters were electrodynamically levitated, ignited, and burnt in atmospheric air. The particle combustion evolution was recorded by high-speed cinematography. Instant temperature and thermal radiation intensity were measured using two-wavelength pyrometry and photomultiplier tube methods. Ignition of the magnesium particle is prompt and substantially advances the aluminum particle by 10 ms. Burning time of the aluminum particles is extended 3 to 5 times longer than the magnesium particles. Exponents of a power-law fit of the burning rates are 1.55 and 1.24 for aluminum and magnesium particles, respectively. Flame temperature is slightly lower than the oxide melting temperature. For the aluminum, dimensionless flame diameter is inert to the initial particle size, but for the magnesium inversely proportional to the initial diameter.

    Arnon D. Cohen


    Full Text Available Burn trauma is an important public health concern, with increased risk for burns in children. A cross-sectional study was performed to describe the epidemiological characteristics and risk factors for burns in hospitalized Bedouin children in Soroka University Medical Center during the years 2001–2002. In a population of 558 hospitalized burn-injured patients, 282 Bedouin children were identified. Two hundred and sixty five patients (94.0% had burns involving less than 20% of the body surface area. Cause of the burns was scald in 190 patients (67.4%, fire in 80 patients (28.4%, chemical in 8 patients (2.8%, and explosion in 2 patients (0.7%. Two female patients (0.7% aged 11 and 17 years died of their burns that were caused by fire. The mean length of hospitalization was 9.8 days. Pediatric burn injury has become a significant public health problem in the Bedouin population of the Negev. To reduce the burden of burn injury, it is necessary to increase current efforts in prevention of burns.

    The present study was conducted on rehabilitation and social adjustment of people with burns in society with the main objective to determine the relationship between social adjustment of people with burns and their psychosocial rehabilitation. The study was limited to the Burn Unit, Khyber Teaching Hospital, Peshawar, Pakistan. At bi-variate level, the following were observed: the relationship of psychosocial rehabilitation was highly significant (P=0.000) considering that people with burns feel shame in the society, a highly significant relation (P=0.000) was found between psychosocial rehabilitation and burn as the hurdle to contact other members of the society, a highly significant (P=0.000) relation was found between psychosocial rehabilitation and perception that society provides social support to people with burns, a highly significant (P=0.000) relationship between psychosocial rehabilitation and people with burns feel alienated from the society, a significant association (P=0.024) was found between psychosocial rehabilitation and loss of social network, and a significant (P=0.002) association between psychosocial rehabilitation and society insult toward people with burns. Regular provision of treatment, quota in job allocation for people with burns, initiation of stipend through Benazir Income Support Program, and keeping and updating record of burns at the district level in census centers were suggested as recommendations in light of the study.

  14. Burn wound: Pathophysiology and its management by herbal plants

    Directory of Open Access Journals (Sweden)

    Dhirender Kaushik


    Full Text Available In human body, wound healing is a normal biological phenomenon. Burns may be acute or chronic depending upon the source and its time of exposure. Burn wounds may be superficial, partial or full thickness wounds. When skin comes in contact with higher temperature, protein denaturation takes place due to which the plasma membrane integrity is lost. When skin is burned, a number of inflammatory mediators and releasing agents such as histamine, nitric oxide, oxygen free radicals, eicosanoid products, tumor necrosis factors, and interleukins etc., are released at the site. For wound healing mechanism, the keratinocytes has to move from uninjured site to the burned area. For deeper burns this process takes a long time. By some unknown mechanisms, burn wounds may convert from one form to another form. So burn wound depth must be accurately measured before starting the treatment to prevent the complications. Burns can be induced in experimental animals by using different models. Many treatments such as herbal drugs, topical agents, gene therapy, volume therapy, and rehabilitation can be employed. This review article mainly deals with the theoretical and practical aspects of burn wound healing. Some burn wound healing plants with their chemical constituents, plant part used, uses and animal models are described here.

  15. Oxidative stress and anti-oxidative mobilization in burn injury. (United States)

    Parihar, Arti; Parihar, Mordhwaj S; Milner, Stephen; Bhat, Satyanarayan


    A severe burn is associated with release of inflammatory mediators which ultimately cause local and distant pathophysiological effects. Mediators including Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) are increased in affected tissue, which are implicated in pathophysiological events observed in burn patients. The purpose of this article is to understand the role of oxidative stress in burns, in order to develop therapeutic strategies. All peer-reviewed, original and review articles published in the English language literature relevant to the topic of oxidative stress in burns in animals and human subjects were selected for this review and the possible roles of ROS and RNS in the pathophysiology of burns are discussed. Both increased xanthine oxidase and neutrophil activation appear to be the oxidant sources in burns. Free radicals have been found to have beneficial effects on antimicrobial action and wound healing. However following a burn, there is an enormous production of ROS which is harmful and implicated in inflammation, systemic inflammatory response syndrome, immunosuppression, infection and sepsis, tissue damage and multiple organ failure. Thus clinical response to burn is dependent on the balance between production of free radicals and its detoxification. Supplementation of antioxidants in human and animal models has proven benefit in decreasing distant organ failure suggesting a cause and effect relationship. We conclude that oxidative damage is one of the mechanisms responsible for the local and distant pathophysiological events observed after burn, and therefore anti-oxidant therapy might be beneficial in minimizing injury in burned patients.

  16. Evaluation of burn injuries related to liquefied petroleum gas. (United States)

    Tarim, Mehmet Akin


    Liquefied petroleum gas (LPG) is a fuel that is widely used for domestic, agricultural, and industrial purposes. LPG is also commonly used in restaurants, industries, and cars; however, the home continues to be the main site for accidents. In Turkey, the increased usage of LPG as a cooking or heating fuel has resulted in many burn injuries from LPG mishaps. Between January 2000 and June 2011, 56 LPG-burned patients were compared with 112 flame-burned patients. There were no significant differences with respect to the mean age, sex, hospitalization time, and mortality in both groups. In the LPG-caused burn cases, 41 burns (73.2%) occurred at home, seven (12.5) were work-related mishaps, and eight (14.3) were associated with car accidents. The majority of the LPG burns (82%, 46 patients) resulted from a gas leak, and 18% of them were related to the failure to close LPG tubes in the patients' kitchens (10 patients). Burns to the face and neck (82 vs 67%, P = .039) and upper (62 vs 23%, P = .000) and lower (70 vs 45%, P = .002) extremities were significantly higher in LPG-caused burn cases than flame-burned cases. General awareness regarding the risk of LPG and first aid for burns appears to be lacking. The LPG delivery system should be standardized throughout countries that widely use LPG.

  17. Burn patients' experience of pain management: a qualitative study. (United States)

    Yuxiang, Li; Lingjun, Zhou; Lu, Tang; Mengjie, Liu; Xing, Ming; Fengping, Shen; Jing, Cui; Xianli, Meng; Jijun, Zhao


    Pain is a major problem after burns and researchers continue to report that pain from burns remains undertreated. The inadequate pain control results in adverse sequalae physically and psychologically in the burn victims. A better understanding of a burn patient's experience is important in identifying the factors responsible for undertreated pain and establishing effective pain management guidelines or recommendation in the practice of pain relief for burn injuries. This study sought to explore and describe the experience that patients have about pain related to burn-injury during hospitalization. Semi-structured interviews were conducted on eight patients with moderate to severe pain from burn injuries recruited from a Burn Centre in Northwest China. Data was collected by in-depth interviews and qualitative description after full transcription of each interview. Analysis involved the identification of themes and the development of a taxonomy of patients' experience of burn pain and its management. Three themes were indentified: (1) patients' experience of pain control, (2) patients' perception on burn pain management, and (3) patients' expectation of burn pain management. Findings from this study suggested that patients experience uncontrolled pain both physically and psychologically which may serve as an alert for awareness of health professionals to recognize and establish a multidisciplinary pain management team for burn victims, including surgeons, critical care specialists, anesthesiologists, nurses, psychologists, and social workers to accomplish safe and effective strategies for pain control to reach an optimal level of pain management in burn patients. It also provides insights and suggestions for future research directions to address this significant clinical problem.

  7. Proposing "the burns suite" as a novel simulation tool for advancing the delivery of burns education. (United States)

    Sadideen, Hazim; Wilson, David; Moiemen, Naiem; Kneebone, Roger


    Educational theory highlights the importance of contextualized simulation for effective learning. We explored this concept in a burns scenario in a novel, low-cost, high-fidelity, portable, immersive simulation environment (referred to as distributed simulation). This contextualized simulation/distributed simulation combination was named "The Burns Suite" (TBS). A pediatric burn resuscitation scenario was selected after high trainee demand. It was designed on Advanced Trauma and Life Support and Emergency Management of Severe Burns principles and refined using expert opinion through cognitive task analysis. TBS contained "realism" props, briefed nurses, and a simulated patient. Novices and experts were recruited. Five-point Likert-type questionnaires were developed for face and content validity. Cronbach's α was calculated for scale reliability. Semistructured interviews captured responses for qualitative thematic analysis allowing for data triangulation. Twelve participants completed TBS scenario. Mean face and content validity ratings were high (4.6 and 4.5, respectively; range, 4-5). The internal consistency of questions was high. Qualitative data analysis revealed that participants felt 1) the experience was "real" and they were "able to behave as if in a real resuscitation environment," and 2) TBS "addressed what Advanced Trauma and Life Support and Emergency Management of Severe Burns didn't" (including the efficacy of incorporating nontechnical skills). TBS provides a novel, effective simulation tool to significantly advance the delivery of burns education. Recreating clinical challenge is crucial to optimize simulation training. This low-cost approach also has major implications for surgical education, particularly during increasing financial austerity. Alternative scenarios and/or procedures can be recreated within TBS, providing a diverse educational immersive simulation experience.

  8. Efficacy of a probiotic and chlorhexidine mouth rinses: A short-term clinical study

    Directory of Open Access Journals (Sweden)

    Harini P


    Full Text Available Introduction: Probiotic technology represents a breakthrough approach to maintaining oral health by utilizing natural beneficial bacteria commonly found in healthy mouths to provide a natural defense against those bacteria thought to be harmful to teeth and gums. However, data are still sparse on the probiotic action in the oral cavity. The review article on probiotics in children published by Twetman and Stecksen- Blicks in 2008 showed only one study of dental interest on probiotics in children. Aim and Objectives: The present study evaluated clinically the efficacy of a probiotic and chlorhexidine mouth rinses on plaque and gingival accumulation in children. The trial design is a double-blind parallel group, 14 days comparative study between a probiotic mouth rinse and a chlorhexidine mouth rinse, which included 45 healthy children in the age group of 6-8 years. Results: The Probiotic and Chlorhexidine groups had less plaque accumulations compared with the Control group at the end of 14 years (P < 0.001 and P < 0.001, respectively. But, unlike the plaque score, there was a significant difference in the Gingival Index between the Probiotic and the Chlorhexidine groups (P = 0.009, Probiotic group being better than the Chlorhexidine group (mean = 0.2300 and 0.6805, respectively. Conclusion: The Probiotic mouth rinse was found effective in reducing plaque accumulation and gingival inflammation. Therefore, probiotic mouth rinse obviously has a potential therapeutic value and further long-term study is recommended to determine its efficacy.


    Institute of Scientific and Technical Information of China (English)


    Objective: To verify the moisture maintaining effect of moist exposed burn ointment (MEBO) in treating burn wound. Methods: Rabbit model with II degree burn wound was used in this study. Observations were conducted at 0 (before burn), 0.5, 6, 24, 48, 72, and 168 hours postburn. The data of wound water evaporation, wound appearance and pathological changes of the wounds were compared with that of the burn wounds treated with Vaseline or conventional dry exposed therapy. Results: It was found that wounds treated with MEBO had water evaporation close to that of normal skin and was significantly less than that of the wounds treated with dry exposed therapy (P<0.01) MEBO did not obstruct water evaporation from wound as Vaseline did(P<0.01).Wounds treated with MEBO had good permeability and adequate drainage. Conclusion: MEBO provided the wounds with a physiological moist environment

  10. Firefighter burn injuries: predictable patterns influenced by turnout gear. (United States)

    Kahn, Steven A; Patel, Jignesh H; Lentz, Christopher W; Bell, Derek E


    Approximately 100 firefighters suffer fatal injuries annually and tens of thousands receive nonfatal injuries. Many of these injuries require medical attention and restricted activity but may be preventable. This study was designed to elucidate etiology, circumstances, and patterns of firefighter burn injury so that further prevention strategies can be designed. In particular, modification of protective equipment, or turnout gear, is one potential strategy to prevent burn injury. An Institutional Review Board-approved retrospective review was conducted with records of firefighters treated for burn injury from 2005 to 2009. Data collected included age, gender, TBSA, burn depth, anatomic location, total hospital days per patient, etiology, and circumstances of injury. Circumstances of injury were stratified into the following categories: removal/dislodging of equipment, failure of equipment to protect, training errors, and when excessive external temperatures caused patient sweat to boil under the gear. Over the 4-year period, 20 firefighters were treated for burn injury. Mean age was 38.9 ± 8.9 years and 19 of 20 patients were male. Mean burn size was 1.1 ± 2.7% TBSA. Eighteen patients suffered second-degree burns, while two patients suffered first-degree burns. Mean length of hospitalization was 2.45 days. Scald burns were responsible for injury to 13 firefighters (65%). Flame burns caused injury to four patients (20%). Only three patients received contact burns (15%). The face was the site most commonly burned, representing 29% of injuries. The hand/wrist and ears were the next largest groups, with 23 and 16% of the injuries, respectively. Other areas burned included the neck (10%), arm (6.5%), leg (6.5%), knees (3%), shoulders (3%), and head (3%). Finally, the circumstance of injury was evaluated for each patient. Misuse and noncontiguous areas of protective equipment accounted for 14 of the 20 injuries (70%). These burns were caused when hot steam

  11. Burn-injured adolescents report gaining multiple developmental benefits and improved life skills as a result of burn camp attendance. (United States)

    Rimmer, Ruth Brubaker; Pressman, Melissa S; Takach, Oliver P; Bay, R Curtis; Croteau, Renee; Hansen, Linda D; Foster, Kevin N; Caruso, Daniel M


    Anecdotally, burn camp has been reported to be a positive developmental and rehabilitative experience for attendees; there is little empirical data to support this belief. This study sought to explore whether burn camp either directly or indirectly elicits positive development outcomes in pediatric burn survivors or increases their psychosocial well-being and achievement. The Youth Experience Survey 2.0, a 66-item self-report inventory designed to measure developmental experiences in an organized youth activity, was administered to children aged 11 to 18 years attending summer burn camp. One hundred and ten burn-injured youth, 58 male and 52 female, reported that burn camp had positively impacted their lives through improved identity exploration, goal-setting and problem-solving abilities, increased physical activity, communication, emotional regulation, and time management skills (P camp for more than 5 years resulted in greater improvement. Study results support the burn camp experience as a far-reaching and positive developmental activity. Participants credited the camp experience with helping them with identity formation and reflection, improved social interactions, and increased initiative; all positive developmental outcomes for youth. Results suggest that burn camp participation not only helps burn-injured youth to deal with their burns but also assists them in the development of social and basic life skills, which will allow them to navigate the transition from youth to adulthood, more effectively and successfully.

    Large rivers create major gaps in reef distribution along tropical shelves. The Amazon River represents 20% of the global riverine discharge to the ocean, generating up to a 1.3 × 106–km2 plume, and extensive muddy bottoms in the equatorial margin of South America. As a result, a wide area of the tropical North Atlantic is heavily affected in terms of salinity, pH, light penetration, and sedimentation. Such unfavorable conditions were thought to imprint a major gap in Western Atlantic reefs. We present an extensive carbonate system off the Amazon mouth, underneath the river plume. Significant carbonate sedimentation occurred during lowstand sea level, and still occurs in the outer shelf, resulting in complex hard-bottom topography. A permanent near-bottom wedge of ocean water, together with the seasonal nature of the plume’s eastward retroflection, conditions the existence of this extensive (~9500 km2) hard-bottom mosaic. The Amazon reefs transition from accretive to erosional structures and encompass extensive rhodolith beds. Carbonate structures function as a connectivity corridor for wide depth–ranging reef-associated species, being heavily colonized by large sponges and other structure-forming filter feeders that dwell under low light and high levels of particulates. The oxycline between the plume and subplume is associated with chemoautotrophic and anaerobic microbial metabolisms. The system described here provides several insights about the responses of tropical reefs to suboptimal and marginal reef-building conditions, which are accelerating worldwide due to global changes.

  13. Prognostic indicators in acute burned patients-a review

    Institute of Scientific and Technical Information of China (English)

    Sherif Emara


    Burn trauma is in need for prognostic indicators or admission scores. This aims for realistic documentation of the burn injury, expectation of the prognosis, and to facilitate a patient stratification to evaluate therapeutic strategies. A computer search through different medical websites was performed looking for articles correlating prognosis with different burn indices. These were carefully summarized and analyzed for this review. Variable studies were found related to that issue; the reliable indicators found had been classified as general or specific. All of them had certain clinical importance, but limitations are a common feature. All the listed indices are useful to serve in the only special clinical situations. We couldn't claim that they are actual prognostic indicator in burn victims. We believe that we still lack the proper prognostic indicator in burn patients. Researchers are invited for more effort to organize a more reliable prognostic indicator and scoring system for burn patients.

    Durán-Vega, Héctor César; Romero-Aviña, Francisco Javier; Gutiérrez-Salgado, Jorge Eduardo; Silva-Díaz, Teresita; Ramos-Durón, Luis Ernesto; Carrera-Gómez, Francisco Javier


    Electrolyte abnormalities are common in the severely burned patient. There is little information with regard to the frequency and magnitude of hypomagnesemia, as well as on risk factors for this condition. We performed an observational, retrospective analysis of 35 burned patients treated at the Plastic and Reconstructive Surgery Service at the Hospital Central Sur PEMEX, Mexico City. We determined serum magnesium behavior and divided patients into two groups: the first included 11 patients with burns and hypomagnesemia, and the second, 24 patients with burns but without hypomagnesemia. Risk factor identification was performed. We found patient at risk was the one with more than 40% of 2nd or 3rd degree total burned body area, in day 4 or 10 after the burn, and with hypokalemia, hypocalcemia, or both, and without intravenous (i.v.) supplementation of magnesium. The best way to prevent or avoid major complications is to identify the high-risk patient, or to diagnose earlier.

  15. Feet sunk in molten aluminium: The burn and its prevention. (United States)

    Alonso-Peña, David; Arnáiz-García, María Elena; Valero-Gasalla, Javier Luis; Arnáiz-García, Ana María; Campillo-Campaña, Ramón; Alonso-Peña, Javier; González-Santos, Jose María; Fernández-Díaz, Alaska Leonor; Arnáiz, Javier


    Nowadays, despite improvements in safety rules and inspections in the metal industry, foundry workers are not free from burn accidents. Injuries caused by molten metals include burns secondary to molten iron, aluminium, zinc, copper, brass, bronze, manganese, lead and steel. Molten aluminium is one of the most common causative agents of burns (60%); however, only a few publications exist concerning injuries from molten aluminium. The main mechanisms of lesion from molten aluminium include direct contact of the molten metal with the skin or through safety apparel, or when the metal splash burns through the pants and rolls downward along the leg. Herein, we report three cases of deep dermal burns after 'soaking' the foot in liquid aluminium and its evolutive features. This paper aims to show our experience in the management of burns due to molten aluminium. We describe the current management principles and the key features of injury prevention.

    Lucía Del Carmen Quezada Berumen


    Full Text Available Facing a severe injury in the children is one of the most devastating experiences that parents may face. The aim of this study was to explore the role of resilience showed by fathers and mothers of children with burns, the TBSA burned, age at the time of the burn and time since the burn in PTSD symptoms in caregivers. It was a cross-sectional study where fathers, mothers and guardians of 51 burn patients were evaluated. Results showed that the higher strength and confidence in caregivers, less severity in PTSD symptoms. The post-burn reactions of parents and guardians can affect the responses and welfare of their children. Therefore, a better understanding of factors related to the adaptation in caregivers, better attention by health services.

    Neutron stars are the most compact stars that can be directly observed, which makes them ideal laboratories to study physics at extreme densities. Neutron stars in low-mass X-ray binaries accrete hydrogen and helium from a lower-mass companion star through Roche lobe overflow. This matter undergoes thermonuclear burning in the neutron star envelope, creating carbon and heavier elements. The fusion process may proceed in an unstable manner, resulting in a thermonuclear runaway. Within one second the entire surface is burned, which is observable as a sharp rise in the emitted X-ray flux: a type I X-ray burst. Afterwards the neutron star surface cools down on a timescale of ten to one hundred seconds. During these bursts the surface of an accreting neutron star can be observed directly, which makes them instrumental for studying this type of stars. We have studied rare kinds of X-ray bursts. One such rare burst is the superburst, which lasts a thousand times longer than an ordinary burst. Superbursts are thought to result from the explosive burning of a thick carbon layer, which lies deeper inside the neutron star, close to a layer known as the crust. A prerequisite for the occurrence of a superburst is a high enough temperature, which is set by the temperature of the crust and the heat conductivity of the envelope. The latter is lowered by the presence of heavy elements that are produced during normal X-ray bursts. Using a large set of observations from the Wide Field Camera's onboard the BeppoSAX satellite, we find that, at high accretion rate, sources which do not exhibit normal bursts likely have a longer superburst recurrence time, than the observed superburst recurrence time of one burster. We analyze in detail the first superburst from a transient source, which went into outburst only 55 days before the superburst. Recent models of the neutron star crust predict that this is too small a time to heat the crust sufficiently for superburst ignition, indicating

    We have examined the potential to provide long-term or even permanent wound coverage in a mouse model of a 30% total body surface area burn using skin allografts. Treatment of the recipient mouse with rabbit anti-mouse thymocyte serum (ATS) followed by donor bone marrow infusion induces a state of specific unresponsiveness to the skin allograft without the need for chronic immunosuppression. Specifically, a B6AF1 mouse receives a burn on Day -2 relative to grafting, ATS on Day -1, and Day +2, a skin allograft from a C3H/He mouse on Day 0, and infusion of C3H/He donor bone marrow on Day +6. We studied three groups of burned mice: Group I, allograft control (n = 5); Group II, allograft plus ATS (n = 12); and Group III, allograft plus ATS and bone marrow infusion (n = 15). Mean graft survival was compared using a one-way analysis of variance and a Student-Newman-Keuls post hoc test. There was no statistical difference in animal mortality among any of the three groups, and there was no evidence of infectious morbidity. Mean skin allograft survival was as follows: Group I, 9 days; Group II, 29 days; and Group III, 66 days (P less than 0.05 vs Group I and II). Nine animals in Group III had intact hair bearing grafts at 90 days when the study was terminated. This study suggests the potential use of induced specific unresponsiveness to skin allografts for wound coverage in thermal injury without use of chronic immunosuppression. In our animal study this was accomplished without increased mortality or apparent infectious morbidity.

  20. The elderly patient with burns: treatment considerations. (United States)

    Staley, M; Richard, R


    When therapists treat elderly patients with burns, they should ask themselves several questions: Am I treating elderly patients with burns "just like other patients with burns?" Am I assessing the patient's joint mobility and strength as critically as I should? Am I ensuring that further tissue trauma is avoided by instructing the nursing staff in turning/transfer techniques? Am I routinely monitoring heart rate and blood pressure? Am I requiring repetition and practice of exercises before the patient's discharge? Is my patient safe to function in the environment to which he or she is being discharged? Most physical changes in the elderly population are attributed to the aging process but often are due to diminished movement disorders arising from poor physical fitness and disuse. The "slowdown" in the older adult may result from a lack of appropriate movement practice and failure to receive reinforcement for activity. Regardless of age, physiological challenges result in enhanced functional status. Training for a specific skill increases performance in that skill just as strength training increases strength. Practice or repetition of a task improves movement and response time for that task. Appropriate physical training programs for the elderly can (1) counterbalance age-associated declines in work capacity and physical performance; (2) maintain and improve range of motion, strength, flexibility, balance, and endurance; and (3) reduce the disability of the cardiovascular, respiratory, and musculoskeletal systems that may result in decreased risk of falls and accidents. Practice of a task and maintenance of physical fitness helps ensure a high level of motor performance and speed as a person grows older. One is never too old to exercise!
