  1. [Respiratory treatments in neuromuscular disease].

    Martínez Carrasco, C; Cols Roig, M; Salcedo Posadas, A; Sardon Prado, O; Asensio de la Cruz, O; Torrent Vernetta, A

    2014-10-01

    In a previous article, a review was presented of the respiratory pathophysiology of the patient with neuromuscular disease, as well as their clinical evaluation and the major complications causing pulmonary deterioration. This article presents the respiratory treatments required to preserve lung function in neuromuscular disease as long as possible, as well as in special situations (respiratory infections, spinal curvature surgery, etc.). Special emphasis is made on the use of non-invasive ventilation, which is changing the natural history of many of these diseases. The increase in survival and life expectancy of these children means that they can continue their clinical care in adult units. The transition from pediatric care must be an active, timely and progressive process. It may be slightly stressful for the patient before the adaptation to this new environment, with multidisciplinary care always being maintained. Copyright © 2013 Asociación Española de Pediatría.

    Full Text Available Stephan Budweiser1, Rudolf A Jörres2, Michael Pfeifer1,31Center for Pneumology, Hospital Donaustauf, Donaustauf, Germany; 2Institute and Outpatient Clinic for Occupational, Social and Environmental Medicine, Ludwig-Maximilians-University, Munich, Germany; 3Department of Internal Medicine II, Division of Respirology, University of Regensburg, Regensburg, GermanyAbstract: Patients with advanced COPD and acute or chronic respiratory failure are at high risk for death. Beyond pharmacological treatment, supplemental oxygen and mechanical ventilation are major treatment options. This review describes the physiological concepts underlying respiratory failure and its therapy, as well as important treatment outcomes. The rationale for the controlled supply of oxygen in acute hypoxic respiratory failure is undisputed. There is also a clear survival benefit from long-term oxygen therapy in patients with chronic hypoxia, while in mild, nocturnal, or exercise-induced hypoxemia such long-term benefits appear questionable. Furthermore, much evidence supports the use of non-invasive positive pressure ventilation in acute hypercapnic respiratory failure. It application reduces intubation and mortality rates, and the duration of intensive care unit or hospital stays, particularly in the presence of mild to moderate respiratory acidosis. COPD with chronic hypercapnic respiratory failure became a major indication for domiciliary mechanical ventilation, based on pathophysiological reasoning and on data regarding symptoms and quality of life. Still, however, its relevance for long-term survival has to be substantiated in prospective controlled studies. Such studies might preferentially recruit patients with repeated hypercapnic decompensation or a high risk for death, while ensuring effective ventilation and the patients’ adherence to therapy.Keywords: respiratory failure, COPD, mechanical ventilation, non-invasive ventilation long-term oxygen therapy, chronic

  3. Mechanism and Clinical Importance of Respiratory Failure Induced by Anticholinesterases

    2017-12-01

    Full Text Available Respiratory failure is the predominant cause of death in humans and animals poisoned with anticholinesterases. Organophosphorus and carbamate anticholinesterases inhibit acetylcholinesterase irreversibly and reversibly, respectively. Some of them contain a quaternary atom that makes them lipophobic, limiting their action at the periphery, i.e. outside the central nervous system. They impair respiratory function primarily by inducing a desensitization block of nicotinic receptors in the neuromuscular synapse. Lipophilic anticholinesterases inhibit the acetylcholinesterase both in the brain and in other tissues, including respiratory muscles. Their doses needed for cessation of central respiratory drive are significantly less than doses needed for paralysis of the neuromuscular transmission. Antagonist of muscarinic receptors atropine blocks both the central and peripheral muscarinic receptors and effectively antagonizes the central respiratory depression produced by anticholinesterases. To manage the peripheral nicotinic receptor hyperstimulation phenomena, oximes as acetylcholinesterase reactivators are used. Addition of diazepam is useful for treatment of seizures, since they are cholinergic only in their initial phase and can contribute to the occurrence of central respiratory depression. Possible involvement of central nicotinic receptors as well as the other neurotransmitter systems – glutamatergic, opioidergic – necessitates further research of additional antidotes.

  4. Cardio-respiratory capacity as an important biomarker of health

    Full Text Available Background: Cardio-respiratory capacity is an important factor in human health. It's quality depends on many objective factors (such as age and gender, but it can be influenced also by others (physical activity, nutrition. Low level of cardio-respiratory capacity significantly correlates with numerous health failures. Objective: Evaluation of the cardio-respiratory capacity in athletes enables a prediction of performance. In a non-sporting population a critically low level of cardio-respiratory capacity could be a warning signal of a high risk of diseases. The Spiroergometric examination needs very sophisticated technical equipment including O2-CO2 analyzer. The aim of the study was to examine the possibility of how to replace direct measurement of oxygen consumption by the method. Methods: 2 777 protocols from the data base of examinations performed in the period of 1994 till 2015 were used. Cardio-respiratory capacity in all examinations was evaluated according to maximal oxygen uptake VO2max, physical working capacity W170 and maximal performance on the cyclo-ergometer. Step-vice increased workload on cyclo-ergometer based on procedure used in International Biological Program was applied to obtain the characteristics of cardio-respiratory capacity of each subject (2 015 men and 762 women. Results: Correlation coefficients r and regression equations of cardio-respiratory capacity characteristics (W170, W170/kg, VO2max, VO2max/kg, Wmax, Wmax/kg were calculated. The highest correlation was found between VO2max and Wmax and between VO2max/kg and Wmax/kg, both in men and women (r = .89 in men and r = .85 in women for VO2max and Wmax. The most important regression equations are: (men VO2max = 0.0095 . Wmax + 0.54 (l/min (r = .89, VO2max/kg = 8.3 . Wmax/kg + 13 (ml/min/kg (r = .83; (women VO2max = 0.0083 .

  6. Evaluation and treatment of respiratory alkalosis.

    Palmer, Biff F

    2012-11-01

    Respiratory alkalosis is the most frequent acid-base disturbance encountered in clinical practice. This is particularly true in critically ill patients, for whom the degree of hypocapnia directly correlates with adverse outcomes. Although this acid-base disturbance often is considered benign, evidence suggests that the alkalemia of primary hypocapnia can cause clinically significant decreases in tissue oxygen delivery. Mild respiratory alkalosis often serves as a marker of an underlying disease and may not require therapeutic intervention. In contrast, severe respiratory alkalosis should be approached with a sense of urgency and be aggressively corrected. Copyright © 2012 National Kidney Foundation, Inc. Published by Elsevier Inc.

Though effective pharmacotherapy options exist, no agent is universally efficacious; therapeutic decisions must account for individual patient preferences. Oral H1-antihistamines, though effective for the common symptoms of allergic rhinitis, have modest decongestant action, as do leukotriene receptor antagonists. Intranasal antihistamines appear to improve congestion better than oral forms. Topical decongestants reduce congestion associated with allergic rhinitis, but local adverse effects make them unsuitable for long-term use. Oral decongestants show some efficacy against congestion in allergic rhinitis and the common cold, and can be combined with oral antihistamines. Intranasal corticosteroids have broad anti-inflammatory activities, are the most potent long-term pharmacologic treatment of congestion associated with allergic rhinitis, and show some congestion relief in rhinosinusitis and nasal polyposis. Immunotherapy and surgery may be used in some cases refractory to pharmacotherapy. Steps in congestion management include (1 diagnosis of the cause(s, (2 patient education and monitoring, (3 avoidance of environmental triggers where possible, (4 pharmacotherapy, and (5 immunotherapy

    2018-05-04

    Respiratory diseases affect millions of people worldwide, and account for significant levels of disability and mortality. The treatment of lung cancer and asthma with therapeutic antibodies (Abs) is a breakthrough that opens up new paradigms for the management of respiratory diseases. Antibodies are becoming increasingly important in respiratory medicine; dozens of Abs have received marketing approval, and many more are currently in clinical development. Most of these Abs target asthma, lung cancer and respiratory infections, while very few target chronic obstructive pulmonary disease - one of the most common non-communicable causes of death - and idiopathic pulmonary fibrosis. Here, we review Abs approved for or in clinical development for the treatment of respiratory diseases. We notably highlight their molecular mechanisms, strengths, and likely future trends.

  11. Membrane humidification--a new method for humidification of respiratory gases in ventilator treatment of neonates.

    Hanssler, L; Tennhoff, W; Roll, C

    1992-01-01

    A humidifier system for neonatology that functions according to the 'membrane humidification' principle was subjected to a performance test in our laboratory. Humidification and heating of the respiratory gases took place in a module consisting of a net of hollow fibres placed inside the incubator. In 18 measurement combinations flow, respiratory gas temperature, and incubator temperature were varied. At respiratory gas temperatures within the range of 33-37 degrees C the minimum international standard for the absolute air humidity in the respiratory gas was achieved or exceeded in all measurements. No controlled clinical tests regarding the importance and long term effects of different temperatures and different humidity levels in the inspiratory air are yet available for the ventilation treatment of neonates.

  12. FEVER IN CHILDREN WITH RESPIRATORY VIRAL INFECTIONS: EFFECTIVE AND SAFE METHODS OF TREATMENT

    T. E. Taranushenko

    2013-01-01

    Full Text Available One of the most important — the problem of treatment of fever in children with respiratory viral infections — is discussed in this article. It is fever as one of the first symptoms of disease which often frightens parents and leads to inappropriate and excess usage of antipyretic agents, which in its turn can cause unfavorable consequences. The authors represent their own data on frequency of antipyretic drugs usage in children with respiratory viral infections, as well as the answers of pediatricians to the questionnaires on methods of choice in temperature normalization. According to the modern Russian as well as European and American clinical guidelines on treatment of fever in children the management of selection of patients demanding antipyretic treatment is detailed, indications and contraindications to such therapy are described, the most effective methods of temperature normalization in children with acute respiratory infection are discussed. The authors suggested the data on recommended dosages of paracetamol, which were revised in 2011 by the UK Medicines Control Agency, to be very useful. The current information on advantages of ibuprofen in comparison to paracetamol in treatment of fever in children with respiratory viral infections is shown. The main target of this article is understanding and acceptance by pediatricians of the modern recommendation on differential and reasonable approach to administration of antipyretic drugs in children with respiratory viral infections.

    Full Text Available to improve treatment results in premature infants with neonatal respiratory distress syndrome (NRDS, by establishing developmental mechanisms and elaborating methods for its early diagnosis, treatment, and prevention. Material and methods. The paper analyzes the results of a clinical observation and laboratory, instrumental, immunological, morphological, and radiological studies of 320 premature neonates at 26—35 weeks gestational age. The following groups of neonates were identified: 1 40 premature neonatal infants without NRDS and with the physiological course of an early neonatal period (a comparison group; 2 190 premature neonates with severe NRDS in whom the efficiency of therapy with exogenous surfactants, such as surfactant BL versus curosurf, was evaluated; 3 90 premature newborn infants who had died from NRDS at its different stages. Results. The poor maternal somatic, obstetric, and gynecological histories in the early periods of the current pregnancy create prerequisites for its termination, favor the development of severe acute gestosis, and cause abnormal placental changes. Each gestational age is marked by certain placental changes that promote impaired uterineplacentalfetal blood flow and premature birth. Alveolar and bronchial epithelial damages, including those ante and intranatally, microcircula tory disorders play a leading role in the tanatogenesis of NRDS. Intranatal hypoxia and amniotic fluid aspiration are one of the important factors contributing to alveolar epithelial damage and NRDS in premature neonates. Exogenous surfactants prevent the development of hyaline membranes and are useful in the normalization of ventilation-perfusion relationships and lung biomechanical properties. Conclusion. This study could improve the diagnosis and treatment of NRDS, which assisted in reducing the duration of mechanical ventilation from 130±7.6 to 65±11.6 hours, the number of complications (the incidence of intragastric

    The study investigated treatment outcomes when respiratory physiotherapy was delivered by non-respiratory on-call physiotherapists, compared with specialist respiratory physiotherapists. Prospective, randomised crossover trial. Paediatric, tertiary care hospital in the United Kingdom. Mechanically ventilated children requiring two physiotherapy interventions during a single day were eligible. Twenty two physiotherapists (10 non-respiratory) and 93 patients were recruited. Patients received one treatment from a non-respiratory physiotherapist and another from a respiratory physiotherapist, in a randomised order. Treatments were individualised to the patients' needs, often including re-positioning followed by manual lung inflations, chest wall vibrations and endotracheal suction. The primary outcome was respiratory compliance. Secondary outcomes included adverse physiological events and clinically important respiratory changes (according to an a priori definition). Treatments delivered to 63 patients were analysed. There were significant improvements to respiratory compliance (mean increase [95% confidence intervals], 0.07 and 0.08ml·cmH2O(-1)·kg(-1) [0.01 to 0.14 and 0.04 to 0.13], pphysiotherapy services, both during and outside of normal working hours.

    To describe Dutch respiratory nurses' current smoking cessation practices, attitudes and beliefs, and to compare these with a survey from the year 2000, before the national introduction of a protocol for the treatment of nicotine and tobacco addiction (the L-MIS protocol). Questionnaire survey among all 413 registered respiratory nurses in the Netherlands in 2006. The response rate was 62%. Seventy-seven percent of the respondents reported to have "fairly good" or "good" knowledge of all steps of the L-MIS protocol. Seven out of 10 behavioural techniques for smoking cessation from the protocol were used by more than 94% of the respondents. Seventy-four percent of the respiratory nurses recommended the use of either nicotine replacement therapy (70%) or bupropion (44%). Almost two-thirds (65% of 254) perceived lack of patient's motivation as the most important barrier for smoking cessation treatment; a four-fold increase compared to the year 2000. We conclude that respiratory nurses are compliant with the L-MIS protocol. They offer intensive support and use behavioural techniques for smoking cessation more frequently than evidence-based pharmacological aids for smoking cessation. Perceived lack of patient's motivation forms the most important threat to respiratory nurses' future smoking cessation activities. International guidelines acknowledge that respiratory patients have a more urgent need to stop smoking but have more difficulty doing so. They should be offered the most intensive smoking cessation counselling in combination with pharmacotherapy. This kind of counselling may be more feasible for respiratory nurses than for physicians who often lack time. Their efforts could be increased by reimbursing pharmacological aids for smoking cessation and by developing simple tools to systematically assess motivation to quit and psychiatric co-morbidity in smoking patients.

  1. Clinical requirements in the treatment of today's respiratory tract infections.

    Höffken, G

    1993-01-01

    Respiratory tract infections (RTIs) are among the most frequent infections in man and lower tract infections account substantially for the overall mortality in hospitals. Regarding the etiology of pneumonias, one has to consider different pathogenic mechanisms, age of the patients, underlying diseases, concomitant medications, symptomatologies, seasonal influences, and clinical conditions, e.g. intensive care environment and mechanical ventilation. To optimize the rational management of respiratory infections, identification of the etiologic agent would be desirable. The decision of how to treat is often based on epidemiologic, clinical, and radiological assessments. Epidemiologic studies have shown a pronounced difference in the etiologic spectrum between community- and hospital-acquired RTIs. In community-acquired pneumonias, pneumococci, Haemophilus influenzae, Legionella, Mycoplasma and viruses predominate, whereas in nosocomially acquired pneumonias, Enterobacteriaceae, e.g. Klebsiella, Proteus, Enterobacter as well as Pseudomonas and staphylococci comprise the most frequent isolates. Empirical therapy has to cover all possible etiologic pathogens which most likely cause the infection. In addition, an adequate kinetic profile, e.g. once or twice daily dosing, sufficient pulmonary tissue or fluid penetration, and acceptable tolerance and costs are prerequisites for optimal therapy. Drugs of choice for the treatment of community-acquired pneumonia are aminobenzylpenicillins or macrolides. Oral cephalosporins exhibit excellent activity against many bacterial pathogens of typical community-acquired pneumonia, and are active against beta-lactamase-producing H. influenzae.

  2. Aromaphytobalneotherapy in Treatment and Prophylaxis of Frequent Respiratory Infections in Children with Chronic and Disabling Diseases

    O. M. Konova

    2016-01-01

    Full Text Available In children with chronic pathologies, co-occurring frequent respiratory infections of a prolonged course obstructs and reduce the effectiveness of rehabilitation measures, and adversely affect the adaptation reserves. Hydrotherapeutic factors are widely used for the prevention of colds in children from the first days of life. Addition to the water of medicinal and phytoaromatic preparations increases their efficiency. For patients with chronic pathology, when prescribing balneotherapeutic factors for treatment and prophylaxis of respiratory infections, it is important to take into account the potential risk of adverse effects on the symptoms of the underlying disease. Researches in patients with orthopedic, chronic gastroenterological diseases, spastic forms of cerebral palsy, with co-occurring frequent respiratory infections of a prolonged course in history revealed that addition of medicinal baths based on phytoaromatic preparation, containing eucalyptus oil, to the rehabilitation complex is an effective method of preventing and stopping initial symptoms of respiratory infections. It also contributes to the adaptation reserves of the organism, without adversely affecting the course of the underlying disease.

    1991-02-01

    Respiratory ailments are important causes of morbidity and mortality in developing countries. Ethnobotanical surveys and literature reviews conducted in Guatemala during 1986-88 showed that 234 plants from 75 families, most of them of American origin, have been used for the treatment of respiratory ailments. Three Gram-positive bacteria causing respiratory infections (Staphylococcus aureus, Streptococcus pneumoniae and Streptococcus pyogenes) were used to screen 68 of the most commonly used plants for activity. Twenty-eight of these (41.2%) inhibited the growth of one or more of the bacteria tested. Staphylococcus aureus was inhibited by 18 of the plant extracts, while 7 extracts were effective against Streptococcus pyogenes. Plants of American origin which exhibited antibacterial activity were: Gnaphalium viscosum, Lippia alba, Lippia dulcis, Physalis philadelphica, Satureja brownei, Solanum nigrescens and Tagetes lucida. These preliminary in vitro results provide scientific basis for the use of these plants against bacterial respiratory infections.

  5. [Management and treatment of respiratory failure associated with amyotrophic lateral sclerosis].

    Danel-Brunaud, V; Perez, T; Just, N; Destée, A

    2005-04-01

    In amyotrophic lateral sclerosis (ALS), respiratory muscle involvement is highly predictive of survival and quality of life (QOL). There is compelling evidence that non invasive ventilation (NIV) prolongs survival by several months and improves QOL more than any other currently available treatment. Frequent testing of pulmonary function and regular evaluations are recommended since 1999 by the American Academy of Neurology in order to take appropriate treatment decisions. There are numerous tests available to evaluate respiratory status in ALS and it is important to know their sensitivity and specificity to recognize clinical risk situations. Some recent data suggest that sniff nasal pressure and maximal inspiratory pressure (MIP) can be performed reliably by most ALS patients and are more sensitive to decrements in inspiratory muscle strength than spirometry or arterial blood gasometry. Airway obstruction caused by ineffective coughing is the principal cause of intolerance to NIV. Several factors other than respiratory muscle strength may affect pulmonary function: postural changes, nutritional status, infectious disease, drugs. The neurologist has to coordinate multidisciplinary care, with attention to individual patient preferences, and with a frank and compassionate discussion between the patient, the family, the physicians and the caregivers.

  7. Laboratory investigation and phylogenetic analysis of an imported Middle East respiratory syndrome coronavirus case in Greece.

    Athanasios Kossyvakis

    Full Text Available Rapid and reliable laboratory diagnosis of persons suspected of Middle East respiratory syndrome coronavirus (MERS-CoV infection is important for timely implementation of infection control practices and disease management. In addition, monitoring molecular changes in the virus can help elucidate chains of transmission and identify mutations that might influence virus transmission efficiency. This was illustrated by a recent laboratory investigation we conducted on an imported MERS-CoV case in Greece. Two oropharyngeal swab specimens were collected on the 1st and 2nd day of patient hospitalization and tested using two real-time RT-PCR (rRT-PCR assays targeting the UpE and Orf-1a regions of the MERS-CoV genome and RT-PCR and partial sequencing of RNA-dependent RNA polymerase and nucleocapsid genes. Serum specimens were also collected and serological test were performed. Results from the first swab sample were inconclusive while the second swab was strongly positive for MERS-CoV RNA by rRT-PCR and confirmed positive by RT-PCR and partial gene sequencing. Positive serologic test results further confirmed MERS-CoV infection. Full-length nucleocapsid and spike gene coding sequences were later obtained from the positive swab sample. Phylogenetic analysis revealed that the virus was closely related to recent human-derived MERS-CoV strains obtained in Jeddah and Makkah, Saudi Arabia, in April 2014 and dromedary camels in Saudi Arabia and Qatar. These findings were consistent with the patient's history. We also identified a unique amino acid substitution in the spike receptor binding domain that may have implications for receptor binding efficiency. Our initial inconclusive rRT-PCR results highlight the importance of collecting multiple specimens from suspect MERS-CoV cases and particularly specimens from the lower respiratory tract.

  9. [Treatment of fungal infections of upper respiratory tract and ear].

    Kurnatowski, Piotr; Kurnatowska, Agnieszka K

    2007-01-01

    Fungi, in comparison with other pathogenic factors, have high pathogenicity. The number of fungal species which are able to infect people is over 500. The upper respiratory tract and ear have permanent contact with external environment which makes their ontocenoses open to continuous exchange of microorganisms of which they consist. In etiology of inflammatory processes 21 species which belonging to 3 genera (Zygomycota, Ascomycota, Basidiomycota) of fungi play important role. Administration of antifungal drugs can be: prophylactic, empiric preemptive and therapeutic. Physicians may prescribe antibiotics (mainly pollens: amphotericin B, natamycin and nystatin) and chemiotherapeutics (mainly azoles and fluorpirymidins, pigments, chlorhexidine and chlorquinaldol). In ENT practice topical and systemic drugs can be administrated. Topical lozenges include amphotericin B, clotrimazole, chlorhexidine or chlorquinaldol and oral gels: nystatin and miconazole. Some of drugs are in the form of suspension/solution, which can be used for inhalation, into the sinus, for swabbing or for lavage: amphotericin B, natamycin, nystatin, clotrimazol, flucytosine, miconazole, fluconazole, vorykonazole, caspofungin.

  11. Accuracy of Robotic Radiosurgical Liver Treatment Throughout the Respiratory Cycle

    Winter, Jeff D.; Wong, Raimond; Swaminath, Anand; Chow, Tom

    2015-01-01

    Purpose: To quantify random uncertainties in robotic radiosurgical treatment of liver lesions with real-time respiratory motion management. Methods and Materials: We conducted a retrospective analysis of 27 liver cancer patients treated with robotic radiosurgery over 118 fractions. The robotic radiosurgical system uses orthogonal x-ray images to determine internal target position and correlates this position with an external surrogate to provide robotic corrections of linear accelerator positioning. Verification and update of this internal–external correlation model was achieved using periodic x-ray images collected throughout treatment. To quantify random uncertainties in targeting, we analyzed logged tracking information and isolated x-ray images collected immediately before beam delivery. For translational correlation errors, we quantified the difference between correlation model–estimated target position and actual position determined by periodic x-ray imaging. To quantify prediction errors, we computed the mean absolute difference between the predicted coordinates and actual modeled position calculated 115 milliseconds later. We estimated overall random uncertainty by quadratically summing correlation, prediction, and end-to-end targeting errors. We also investigated relationships between tracking errors and motion amplitude using linear regression. Results: The 95th percentile absolute correlation errors in each direction were 2.1 mm left–right, 1.8 mm anterior–posterior, 3.3 mm cranio–caudal, and 3.9 mm 3-dimensional radial, whereas 95th percentile absolute radial prediction errors were 0.5 mm. Overall 95th percentile random uncertainty was 4 mm in the radial direction. Prediction errors were strongly correlated with modeled target amplitude (r=0.53-0.66, P<.001), whereas only weak correlations existed for correlation errors. Conclusions: Study results demonstrate that model correlation errors are the primary random source of uncertainty

    Full Text Available Objective: To describe the complete nucleocapsid (N gene region of Middle East respiratory syndrome coronavirus (MERS-CoV from imported case in Malaysia and the relations with human- and camel-derived MERS-CoV. Methods: Combination of throat and nasal swab specimens was subjected to viral RNA extraction. For screening, the extracted RNA was subjected to real-time RT-PCR targeting upstream of E gene, open reading frame 1b and open reading frame 1a. For confirmation, the RNA was subjected to RT-PCR targeting partial part of the RNA-dependent RNA polymerase and nucleocapsid, followed by amplification of complete N gene region. Nucleotide sequencing of the first Malaysian case of MERS-CoV was performed following the confirmation with real-time RT-PCR detection. Results: Initial analysis of partial RNA-dependent RNA polymerase and N gene revealed that the nucleotides had high similarity to Jeddah_1_2013 strain. Analysis of complete N gene region (1 242 nucleotides from the case showed high similarity and yet distinct to the nucleotide sequences of camel-derived MERS-CoV. Conclusions: From the finding, there are possibilities that the patient acquired the infection from zoonotic transmission from dromedary camels.

    Purpose: Volumetric modulated arc therapy (VMAT) is a rotational intensity-modulated radiotherapy (IMRT) technique capable of acquiring projection images during treatment. Treatment plans for lung tumors using stereotactic body radiotherapy (SBRT) are calculated with planning computed tomography (CT) images only exhale phase. Purpose of this study is to evaluate dose distribution by reconstructing from only the data such as respiratory signals and machine parameters acquired during treatment. Methods: Phantom and three patients with lung tumor underwent CT scans for treatment planning. They were treated by VMAT while acquiring projection images to derive their respiratory signals and machine parameters including positions of multi leaf collimators, dose rates and integrated monitor units. The respiratory signals were divided into 4 and 10 phases and machine parameters were correlated with the divided respiratory signals based on the gantry angle. Dose distributions of each respiratory phase were calculated from plans which were reconstructed from the respiratory signals and the machine parameters during treatment. The doses at isocenter, maximum point and the centroid of target were evaluated. Results and Discussion: Dose distributions during treatment were calculated using the machine parameters and the respiratory signals detected from projection images. Maximum dose difference between plan and in treatment distribution was −1.8±0.4% at centroid of target and dose differences of evaluated points between 4 and 10 phases were no significant. Conclusion: The present method successfully evaluated dose distribution using respiratory signals and machine parameters during treatment. This method is feasible to verify the actual dose for moving target

    Adults with chronic lower respiratory disease differ in their barriers to smoking cessation but also suffer from tobacco-related health concerns, which may motivate quit attempts. Few studies have examined differences in tobacco treatment response between smokers with and without chronic lower respiratory disease. We examined the effectiveness of a proactive outreach program for cessation among smokers with and without chronic lower respiratory disease. Subgroup analysis of the Veterans Victory over Tobacco Study, a pragmatic randomized controlled trial that demonstrated the effectiveness of proactive outreach and the choice of tobacco treatments compared with usual care. Smokers identified via the electronic medical record were proactively offered phone-based counseling and care coordination to receive medication from their Veterans Affairs providers or in-person care. We compared the response among those with and without an International Classification of Diseases, 9th Revision diagnosis of a chronic lower respiratory disease (chronic obstructive pulmonary disease, chronic bronchitis, emphysema, asthma). We used stratification by propensity scores to adjust for imbalanced covariates between groups with and without chronic lower respiratory disease within each treatment arm, using complete case analysis accounting for the stratified sampling by site. The study participants were predominantly older, white, male smokers. Overall, 19.6% had chronic lower respiratory disease. A total of 3,307 had outcome data with the following assignments to the intervention: proactive care: n = 1,272 without chronic lower respiratory disease, n = 301 with chronic lower respiratory disease; usual care: n = 1,387 without chronic lower respiratory disease, n = 347 with chronic lower respiratory disease.

  19. Fewer acute respiratory infection episodes among patients receiving treatment for gastroesophageal reflux disease.

    Herng-Ching Lin

    Full Text Available Patients with gastroesophageal reflux disease (GERD present with comorbid complications with implications for healthcare utilization. To date, little is known about the effects of GERD treatment with a proton-pump inhibitor (PPI on patients' subsequent healthcare utilization for acute respiratory infections (ARIs. This population-based study compared ARI episodes captured through outpatient visits, one year before and one year after GERD patients received PPI treatment. We used retrospective data from the Longitudinal Health Insurance Database 2005 in Taiwan, comparing 21,486 patients diagnosed with GERD from 2010 to 2012 with 21,486 age-sex matched comparison patients without GERD. Annual ARI episodes represented by ambulatory care visits for ARI (visits during a 7-day period bundled into one episode, were compared between the patient groups during the 1-year period before and after the index date (date of GERD diagnosis for study patients, first ambulatory visit in the same year for their matched comparison counterpart. Multiple regression analysis using a difference-in-difference approach was performed to estimate the adjusted association between GERD treatment and the subsequent annual ARI rate. We found that the mean annual ARI episode rate among GERD patients reduced by 11.4%, from 4.39 before PPI treatment, to 3.89 following treatment (mean change = -0.5 visit, 95% confidence interval (CI = (-0.64, -0.36. In Poisson regression analysis, GERD treatment showed an independent association with the annual ARI rate, showing a negative estimate (with p<0.001. The study suggests that GERD treatment with PPIs may help reduce healthcare visits for ARIs, highlighting the importance of treatment-seeking by GERD patients and compliance with treatment.

    Paul, Christina; Lin-Shaw, Ammy; Joseph, Mariamma; Kwan, Keith; Sergiacomi, Gianluigi; Mura, Marco

    2016-01-01

    Organising pneumonia (OP) is usually promptly responsive to corticosteroid treatment. We describe a series of 3 cases of severe, progressive, biopsy-proven fibrosing OP causing respiratory failure. All cases presented with peribronchial and subpleural consolidations, had a fibro-inflammatory infiltrative component in the alveolar septa, and only had a partial and unsatisfactory response to corticosteroids. However, they responded to mycophenolic acid (MPA) treatment with resolution of respiratory failure as well as clinical and functional improvement. MPA as an additional treatment option for aggressive forms of fibrosing OP and interstitial lung disease needs to be further explored. © 2016 S. Karger AG, Basel.

    Full Text Available Background: About 100,000 Iranian have been exposed to chemical weapons during Iraq-Iran conflict (1980-88. After being spent of more than two decades, still about 30,000 of them are under follow-up treatment. The main aim of this study was to review various preventive and therapeutic methods for injured patients with sulfur mustard in different phases. Methods: For gathering information, we have used the electronic databases including Scopus, Medline, ISI, IranMedex, Irandoc sites. According to this search strategy, 104 published articles associated to respiratory problems and among them 50 articles related to prevention and treatment of respiratory problems were found and reviewed. Results: There is not any curative treatment for sulfur mustard induced lung injuries, but some valuable experienced measures for prevention and palliative treatments are available. Some useful measures in acute phase include: Symptomatic management, oxygen supplementation, tracheostomy in laryngospasm, use of moist air, respiratory physical therapy, mucolytic agents and bronchodilators. In the chronic phases, these measures include: Periodic clinical examinations, administration of inhaled corticosteroids alone or with long-acting beta 2 agonists, use of antioxidants, magnesium ions, long term oxygen supplement, therapeutic bronchoscopy, laser therapy, and use of respiratory tract stents. Conclusions: Most treatments are symptomatic but using preventive points immediately after exposure could improve following outcomes.

    Zvolensky, Michael J; Rodríguez-Cano, Rubén; Paulus, Daniel J; Kotov, Roman; Bromet, Evelyn; Gonzalez, Adam; Manning, Kara; Luft, Benjamin J

    2017-12-01

    The current study examined whether the interaction of lower respiratory symptoms and anxiety sensitivity is related to smoking lapse in the context of smoking cessation. Participants were adult daily smokers (N=60) exposed to the World Trade Center (WTC) disaster who were in a smoking cessation treatment program (75.0% male, 50.6years old [SD=9.2], and current smoking rate was 17.6 cigarettes per day (SD=10.6). Results indicated that the interaction between lower respiratory symptoms and anxiety sensitivity was a significant predictor of greater risk for lapse (i.e., lower survival time; B=0.005, OR=1.01, p=0.039). Follow-up analysis showed that greater respiratory symptoms were a significant predictor of lapse risk among those with high (B=0.116, OR=1.12, p=0.025), but not those with low (B=-0.048, OR=0.95, p=0.322), levels of anxiety sensitivity. The findings from the current study suggest that smokers with greater respiratory symptoms and higher levels of anxiety sensitivity may be associated with early lapse to smoking following smoking cessation treatment. Future work has the potential to inform the development of tailored cessation interventions for smokers who experience varying levels of lower respiratory symptoms and anxiety sensitivity.

    2018-01-01

    Fisheries interactions are the most serious threats for sea turtle populations. Despite the existence of some rescue centres providing post-traumatic care and rehabilitation, adequate treatment is hampered by the lack of understanding of the problems incurred while turtles remain entrapped in fishing gears. Recently it was shown that bycaught loggerhead sea turtles ( Caretta caretta ) could experience formation of gas emboli (GE) and develop decompression sickness (DCS) after trawl and gillnet interaction. This condition could be reversed by hyperbaric O 2 treatment (HBOT). The goal of this study was to assess how GE alters respiratory function in bycaught turtles before recompression therapy and measure the improvement after this treatment. Specifically, we assessed the effect of DCS on breath duration, expiratory and inspiratory flow and tidal volume ( V T ), and the effectiveness of HBOT to improve these parameters. HBOT significantly increased respiratory flows by 32-45% while V T increased by 33-35% immediately after HBOT. Repeated lung function testing indicated a temporal increase in both respiratory flow and V T for all bycaught turtles, but the changes were smaller than those seen immediately following HBOT. The current study suggests that respiratory function is significantly compromised in bycaught turtles with GE and that HBOT effectively restores lung function. Lung function testing may provide a novel means to help diagnose the presence of GE, be used to assess treatment efficacy, and contribute to sea turtle conservation efforts.

    2006-01-01

    Respiratory gating can reduce the apparent respiratory motion during imaging and treatment; however, residual motion within the gating window remains. Respiratory training can improve respiratory reproducibility and, therefore, the efficacy of respiratory-gated radiotherapy. This study was conducted to determine whether residual motion during respiratory gating is affected by patient, tumour or treatment characteristics. The specific aims of this study were to: (1) identify significant characteristics affecting residual motion, (2) investigate time trends of residual motion over a period of days (inter-session) and (3) investigate time trends of residual motion within the same day (intra-session). Twenty-four lung cancer patients were enrolled in an Institutional Review Board (IRB)-approved protocol. For approximately five sessions, 331 four-minute, respiratory motion traces were acquired with free breathing, audio instructions and audio-visual biofeedback for each patient. The residual motion was quantified by the standard deviation of the displacement within the gating window. The generalized linear model was used to obtain coefficients for each variable within the model and to evaluate the clinical and statistical significance. The statistical significance was determined by a p-value <0.05, while effect sizes of ≥0.1 cm (one standard deviation) were considered clinically significant. This data analysis was applied to patient, tumour and treatment variables. Inter- and intra-session variations were also investigated. The only variable that was significant for both inhale- and exhale-based gating was disease type. In addition, visual-training displacement, breathing type and Karnofsky performance status (KPS) values were significant for inhale-based gating, and dose-per-fraction was significant for exhale-based gating. Temporal respiratory variations within and between sessions were observed for individual patients. However inter- and intra-session analyses did

    Viral respiratory tract infections are the most common human ailments, leading to enormous health and economic burden. Hundreds of viral species and subtypes have been associated with these conditions, with influenza viruses, respiratory syncytial virus, and rhinoviruses being the most frequent and with the highest burden. When considering prevention or treatment of viral respiratory tract infections, potential targets include the causative pathogens themselves but also the immune response, disease transmission, or even just the symptoms. Strategies targeting all these aspects are developing concurrently, and several novel and promising approaches are emerging. In this perspective we overview the entire range of options and highlight some of the most promising approaches, including new antiviral agents, symptomatic or immunomodulatory drugs, the re-emergence of natural remedies, and vaccines and public health policies toward prevention. Wide-scale prevention through immunization appears to be within reach for respiratory syncytial virus and promising for influenza virus, whereas additional effort is needed in regard to rhinovirus, as well as other respiratory tract viruses.

    Background Appropriate intervention is critical in reducing deaths among under-five, severe acutely malnourished (SAM) children with danger signs of severe pneumonia; however, there is paucity of data on outcome of World Health Organisation (WHO) recommended interventions of SAM children with severe pneumonia. We sought to evaluate outcome of the interventions in such children. Methods We prospectively enrolled SAM children aged 0–59 months, admitted to the Intensive Care Unit (ICU) or Acute Respiratory Infection (ARI) ward of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), between April 2011 and June 2012 with cough or respiratory difficulty and radiological pneumonia. All the enrolled children were treated with ampicillin and gentamicin, and micronutrients as recommended by the WHO. Comparison was made among pneumonic children with (n = 111) and without WHO defined danger signs of severe pneumonia (n = 296). The outcomes of interest were treatment failure (if a child required changing of antibiotics) and deaths during hospitalization. Further comparison was also made among those who developed treatment failure and who did not and among the survivors and deaths. Results SAM children with danger signs of severe pneumonia more often experienced treatment failure (58% vs. 20%; ppp<0.01). Conclusion and Significance The result suggests that SAM children with cough or respiratory difficulty and radiologic pneumonia who had WHO-defined danger signs of severe pneumonia more often had treatment failure and fatal outcome compared to those without the danger signs. In addition to danger signs of severe pneumonia, other common causes of both treatment failure and deaths were dehydration, hypocalcaemia, and bacteraemia on admission. The result underscores the importance for further research especially a randomized, controlled clinical trial to validate standard WHO therapy in SAM children with pneumonia especially with

    Pregnancy may be complicated by new-onset or preexisting asthma and allergic rhinitis.This article reviews the recognition and management of asthma and allergic rhinitis during pregnancy, paying close attention to the general principles of allergy and use of asthma medication during pregnancy. Both allergic rhinitis and asthma can adversely affect both maternal quality of life and, in the case of maternal asthma, perinatal outcomes. Optimal management is thus important for both mother and baby. This article reviews the safety of asthma and allergy medications commonly used during pregnancy.

  3. When is respiratory management necessary for partial breast intensity modulated radiotherapy: A respiratory amplitude escalation treatment planning study

    Quirk, Sarah; Conroy, Leigh; Smith, Wendy L.

    2014-01-01

    Purpose: The impact of typical respiratory motion amplitudes (∼2 mm) on partial breast irradiation (PBI) is minimal; however, some patients have larger respiratory amplitudes that may negatively affect dose homogeneity. Here we determine at what amplitude respiratory management may be required to maintain plan quality. Methods and Materials: Ten patients were planned with PBI IMRT. Respiratory motion (2–20 mm amplitude) probability density functions were convolved with static plan fluence to estimate the delivered dose. Evaluation metrics included target coverage, ipsilateral breast hotspot, homogeneity, and uniformity indices. Results: Degradation of dose homogeneity was the limiting factor in reduction of plan quality due to respiratory motion, not loss of coverage. Hotspot increases were observed even at typical motion amplitudes. At 2 and 5 mm, 2/10 plans had a hotspot greater than 107% and at 10 mm this increased to 5/10 plans. Target coverage was only compromised at larger amplitudes: 5/10 plans did not meet coverage criteria at 15 mm amplitude and no plans met minimum coverage at 20 mm. Conclusions: We recommend that if respiratory amplitude is greater than 10 mm, respiratory management or alternative radiotherapy should be considered due to an increase in the hotspot in the ipsilateral breast and a decrease in dose homogeneity

    To secure pH homeostasis, the central respiratory network must permanently adapt its rhythmic motor drive to environment and behaviour. In neonates, it is commonly admitted that the retrotrapezoid/parafacial respiratory group of neurons of the ventral medulla plays the primary role in the respiratory response to acidosis, although the serotonergic system may also contribute to this response. Using en bloc medullary preparations from neonatal mice, we have shown for the first time that the respiratory response to acidosis is abolished after pre-treatment with the serotonin-transporter blocker fluoxetine (25-50 µM, 20 min), a commonly used antidepressant. Using mRNA in situ hybridization and immunohistology, we have also shown the expression of the serotonin transporter mRNA and serotonin-containing neurons in the vicinity of the RTN/pFRG of neonatal mice. These results reveal that the serotonergic system plays a pivotal role in pH homeostasis. Although obtained in vitro in neonatal mice, they suggest that drugs targeting the serotonergic system should be used with caution in infants, pregnant women and breastfeeding mothers.

    The conventional respiratory-gated CT scan technique includes anatomic motion induced artifacts due to the low temporal resolution. They are a significant source of error in radiotherapy treatment planning for the thorax and upper abdomen. Temporal resolution and image quality are important factors to minimize planning target volume margin due to the respiratory motion. To achieve high temporal resolution and high signal-to-noise ratio, we developed a respiratory gated segment reconstruction algorithm and adapted it to Feldkamp-Davis-Kress algorithm (FDK) with a 256-detector row CT. The 256-detector row CT could scan approximately 100 mm in the cranio-caudal direction with 0.5 mm slice thickness in one rotation. Data acquisition for the RS-FDK relies on the assistance of the respiratory sensing system by a cine scan mode (table remains stationary). We evaluated RS-FDK in phantom study with the 256-detector row CT and compared it with full scan (FS-FDK) and HS-FDK results with regard to volume accuracy and image noise, and finally adapted the RS-FDK to an animal study. The RS-FDK gave a more accurate volume than the others and it had the same signal-to-noise ratio as the FS-FDK. In the animal study, the RS-FDK visualized the clearest edges of the liver and pulmonary vessels of all the algorithms. In conclusion, the RS-FDK algorithm has a capability of high temporal resolution and high signal-to-noise ratio. Therefore it will be useful when combined with new radiotherapy techniques including image guided radiation therapy (IGRT) and 4D radiation therapy.

    Full Text Available Kazuhito Sekiguchi, Daijiro Takahashi, Takehiko Hiroma, Tomohiko Nakamura Division of Neonatology, Nagano Children's Hospital, Nagano, Japan Abstract: Urorectal septum malformation sequence can be diagnosed prenatally. We report herein the successful treatment of severe respiratory failure in two patients with urorectal septum malformation sequence and prenatally diagnosed oligohydramnios. The patients showed significant hypoxic deterioration and persistent pulmonary artery hypertension soon after birth. We used high-frequency ventilation (HFO, nitric oxide (NO, and extracorporeal membrane oxygenation (ECMO. The patients were successfully weaned from ECMO and artificial ventilation and discharged to home. Although termination of the pregnancy has often been selected for fetuses with oligohydramnios-related urorectal septum malformation sequence, our results suggest the opportunity for these fetuses to be treated using respiratory supports including HFO, NO, and ECMO after birth.

  10. Leveraging respiratory organ motion for non-invasive tumor treatment devices: a feasibility study

    Möri, Nadia; Jud, Christoph; Salomir, Rares; Cattin, Philippe C.

    2016-06-01

    In noninvasive abdominal tumor treatment, research has focused on minimizing organ motion either by gating, breath holding or tracking of the target. The paradigm shift proposed in this study takes advantage of the respiratory organ motion to passively scan the tumor. In the proposed self-scanning method, the focal point of the HIFU device is held fixed for a given time, while it passively scans the tumor due to breathing motion. The aim of this paper is to present a treatment planning method for such a system and show by simulation its feasibility. The presented planning method minimizes treatment time and ensures complete tumor ablation under free-breathing. We simulated our method on realistic motion patterns from a patient specific statistical respiratory model. With our method, we achieved a shorter treatment time than with the gold-standard motion-compensation approach. The main advantage of the proposed method is that electrically steering of the focal spot is no longer needed. As a consequence, it is much easier to find an optimal solution for both avoiding near field heating and covering the whole tumor. However, the reduced complexity on the beam forming comes at the price of an increased complexity on the planning side as well as a reduced efficiency in the energy distribution. Although we simulate the approach on HIFU, the idea of self-scanning passes over to other tumor treatment modalities such as proton therapy or classical radiation therapy.

    Full Text Available Background. Today, more than 80 % of the world population use herbal medicines. They have different therapeutic effects influencing the whole body. The good efficiency and tolerability of drugs containing Pelargonium sidoides is confirmed by clear scientific criteria and clinical trial data. The purpose of our research was to study the clinical efficiency and safety of the herbal medicine Papalor (Pelargonium sidoides in the treatment of children with acute respiratory viral infections. Materials and methods. The clinical study included 67 boys and 53 girls aged 1 to 12 years. All children were divided into three age groups: 1–2, 3–5 and 6–12 years. Patients of the main group (n = 60 received Papalor, patients of the control group (n = 60 took only symptomatic treatment. The greatest number of children aged 3 to 5 years. Nosological manifestations of acute respiratory viral infections were nasopharyngitis, acute bronchitis and sinusitis. According to the study design, there were three control visits. Results. Analysis of the general criteria of acute respiratory viral infections revealed that the average duration of fever in patients of the main group was 2.7 days, in the control group — 3.4 days, symptoms of intoxication — 2.2 days and 2.9 days, respectively. Catarrhal presentations (runny nose, cough, sore throat lasted for 4.2 days in patients of the main group, in controls — 4.6 days. More than 60 % of patients in both groups had acute bronchitis. At the beginning of treatment, the average level of Bronchitis Severity Score in both groups was almost the same. Already in 3–5 days, there was a significant difference in favor of the main group (p < 0.001, and by the end of treatment (day 7, it was even more expressed. From the start of therapy to its completion, Bronchitis Severity Score improved by 7.4 ± 1.8 in Pelargonium sidoides group compared with 5.2 ± 1.7 in the control group. Conclusions.

  12. Fast Numerical Simulation of Focused Ultrasound Treatments During Respiratory Motion With Discontinuous Motion Boundaries.

    Schwenke, Michael; Georgii, Joachim; Preusser, Tobias

    2017-07-01

    Focused ultrasound (FUS) is rapidly gaining clinical acceptance for several target tissues in the human body. Yet, treating liver targets is not clinically applied due to a high complexity of the procedure (noninvasiveness, target motion, complex anatomy, blood cooling effects, shielding by ribs, and limited image-based monitoring). To reduce the complexity, numerical FUS simulations can be utilized for both treatment planning and execution. These use-cases demand highly accurate and computationally efficient simulations. We propose a numerical method for the simulation of abdominal FUS treatments during respiratory motion of the organs and target. Especially, a novel approach is proposed to simulate the heating during motion by solving Pennes' bioheat equation in a computational reference space, i.e., the equation is mathematically transformed to the reference. The approach allows for motion discontinuities, e.g., the sliding of the liver along the abdominal wall. Implementing the solver completely on the graphics processing unit and combining it with an atlas-based ultrasound simulation approach yields a simulation performance faster than real time (less than 50-s computing time for 100 s of treatment time) on a modern off-the-shelf laptop. The simulation method is incorporated into a treatment planning demonstration application that allows to simulate real patient cases including respiratory motion. The high performance of the presented simulation method opens the door to clinical applications. The methods bear the potential to enable the application of FUS for moving organs.

  15. Uncertainties associated with treatments of hepatic lesions in stereotactic body radiation therapy (SBRT) using respiratory tracking

    Charoy, Marie

    2014-01-01

    Oscar Lambret Center treated with Cyberknife R , since June 2007, liver lesions in stereotactic conditions with respiratory tracking using external LEDs correlated with seeds implanted near the target. Clinical results show excellent local control but there are still uncertainties in the preparation and delivery of treatment. The aims of this thesis are to identify and quantify these uncertainties, to define solutions and/or alternatives and to assess their added value. As a first step, the method of the target definition by the radiation oncologist is evaluated. Improvement of the method currently used in routine is considered, including the choice of the most appropriate imaging and the intervention of a second operator, expert in imaging (radiologist). The organ at risk and target movements induced by the respiratory motion are not taken into account in the treatment planning step, performed on the 3D images (the so-called planning CT). The dosimetric impact associated with this type of planning is evaluated using 4D Monte Carlo simulations that take into account patient and linear accelerator movements and the synchrony between both movements. The question of 4D planning as prospect of improvement is then investigated. Movements and deformations of the liver due to respiration are also implicated in the uncertainties involved in the treatment. The correlation model of external markers with the target, used for respiratory tracking, ignores eventual deformations and rotations within the liver. A study of the impact on the target tracking is performed. All these studies were conducted using real patient data sets. (author) [fr

    as cases of antibiotic treatment failure (ATF). Objectives: We studied antibiotic treatment failure in patients with acute RTIs from a general practitioner (GP) perspective, aiming to explore (i) GPs’ views of ATF in primary care; (ii) how ATF influences the doctor-patient relationship; and (iii) GPs....... GPs used many communicative tools to maintain trust with patients in cases of ATF, but they did not consider such incidents to affect the doctor-patient relationship adversely. Conclusion: These findings suggest a possible communication gap between doctors and patients, partly due to a narrow medical...... definition of ATF. Studies describing patients’ views are still missing. General practitioners’ experiences and views on antibiotic treatment failure in acute respiratory infections or its effects on the doctor–patient relationship have not been studied previously....

  19. Targeting phosphoinositide 3-kinase δ for the treatment of respiratory diseases.

    Sriskantharajah, Srividya; Hamblin, Nicole; Worsley, Sally; Calver, Andrew R; Hessel, Edith M; Amour, Augustin

    2013-03-01

    Asthma and chronic obstructive pulmonary disease (COPD) are characterized in their pathogenesis by chronic inflammation in the airways. Phosphoinositide 3-kinase δ (PI3Kδ), a lipid kinase expressed predominantly in leukocytes, is thought to hold much promise as a therapeutic target for such inflammatory conditions. Of particular interest for the treatment of severe respiratory disease is the observation that inhibition of PI3Kδ may restore steroid effectiveness under conditions of oxidative stress. PI3Kδ inhibition may also prevent recruitment of inflammatory cells, including T lymphocytes and neutrophils, as well as the release of proinflammatory mediators, such as cytokines, chemokines, reactive oxygen species, and proteolytic enzymes. In addition, targeting the PI3Kδ pathway could reduce the incidence of pathogen-induced exacerbations by improving macrophage-mediated bacterial clearance. In this review, we discuss the potential and highlight the unknowns of targeting PI3Kδ for the treatment of respiratory disease, focusing on recent developments in the role of the PI3Kδ pathway in inflammatory cell types believed to be critical to the pathogenesis of COPD. © 2013 New York Academy of Sciences.

  1. Prescriber and Patient Responsibilities in Treatment of Acute Respiratory Tract Infections — Essential for Conservation of Antibiotics

    Antonio C. Pignatari

    2013-06-01

    Full Text Available Inappropriate antibiotic use in normally self-limiting acute respiratory tract infections (RTIs, such as sore throat and the common cold, is a global problem and an important factor for increasing levels of antibiotic resistance. A new group of international experts—the Global Respiratory Infection Partnership (GRIP—is committed to addressing this issue, with the interface between primary care practitioners and their patients as their core focus. To combat the overuse of antibiotics in the community, and facilitate a change from prescribing empiric antibiotic treatment towards cautious deferment combined with symptomatic relief, there is a need to introduce and enhance evidence-based dialogue between primary care practitioners and their patients. Communication with patients should focus on the de-medicalisation of self-limiting viral infections, which can be achieved via a coherent globally endorsed framework outlining the rationale for appropriate antibiotic use in acute RTIs in the context of antibiotic stewardship and conservancy. The planned framework is intended to be adaptable at a country level to reflect local behaviours, cultures and healthcare systems, and has the potential to serve as a model for change in other therapeutic areas.

  2. Hemodialysis Treatment Time: As Important as it Seems?

    Daugirdas, John T

    2017-03-01

    Hemodialysis treatment time and Kt/V can both be considered to be primary measures of hemodialysis adequacy, because when either goes to zero, mortality is certain in patients without residual kidney function. Treatment time is important, but it needs to be adjusted based on surface-area-normalized Kt/V, residual kidney function, and expected ultrafiltration rate. Rescaling dose of dialysis measured as Kt/V to body surface area prevents ultrashort dialysis in small patients, women, and children with minimal residual kidney function. Most if not all of the observational studies of associations between outcome and dialysis session length are probably confounded by dose targeting bias. Once adequate Kt/V (taking into account body surface area) has been provided, adequate dialysis time probably is most relevant in terms of limiting the need for a high fluid removal rate. The latter may adversely impact survival by causing recurrent ischemia to cardiovascular and other tissues. There is little high-quality evidence at this time to support a minimum 4-hour treatment time for all patients, regardless of body size, solute removal, or residual kidney function. On the other hand, there is little evidence that prolonging weekly treatment time up to 24 hours per week is harmful. The final decision regarding treatment time is best individualized, based on patient acceptability and experience, residual kidney function, body surface-area-normalized Kt/V, and expected ultrafiltration rate. © 2017 Wiley Periodicals, Inc.

  3. Aspirin-exacerbated respiratory disease: Prevalence, diagnosis, treatment, and considerations for the future

    Stoner, Ashley N.; Borish, Larry

    2016-01-01

    Aspirin-exacerbated respiratory disease (AERD) is a late onset condition characterized by the Samter triad (aspirin sensitivity [as well as sensitivity to any nonselective cyclooxygenase inhibitor], nasal polyps, asthma) and additional features, including eosinophilic chronic rhinosinusitis, hypereosinophilia, anosmia, frequent absence of atopy, and, intolerance to ingestion of red wine and other alcoholic beverages. The diagnosis is rare, and, because of this, it is also often missed by physicians. However, it is highly overexpressed in patients with severe asthma (and severe chronic rhinosinusitis with nasal polyps), which makes its recognition essential. For this review, we considered mechanisms involved in the pathogenesis of this disease and discussed the clinical symptoms of AERD. We also discussed the role of aspirin desensitization in the treatment of AERD. Also, we considered medications (e.g, leukotriene modifiers) and surgical interventions that have a role in the treatment of AERD. PMID:28124651

  4. Poster - 49: Assessment of Synchrony respiratory compensation error for CyberKnife liver treatment

    Liu, Ming; Cygler, Joanna; Vandervoort, Eric

    2016-01-01

    The goal of this work is to quantify respiratory motion compensation errors for liver tumor patients treated by the CyberKnife system with Synchrony tracking, to identify patients with the smallest tracking errors and to eventually help coach patient’s breathing patterns to minimize dose delivery errors. The accuracy of CyberKnife Synchrony respiratory motion compensation was assessed for 37 patients treated for liver lesions by analyzing data from system logfiles. A predictive model is used to modulate the direction of individual beams during dose delivery based on the positions of internally implanted fiducials determined using an orthogonal x-ray imaging system and the current location of LED external markers. For each x-ray pair acquired, system logfiles report the prediction error, the difference between the measured and predicted fiducial positions, and the delivery error, which is an estimate of the statistical error in the model overcoming the latency between x-ray acquisition and robotic repositioning. The total error was calculated at the time of each x-ray pair, for the number of treatment fractions and the number of patients, giving the average respiratory motion compensation error in three dimensions. The 99 th percentile for the total radial error is 3.85 mm, with the highest contribution of 2.79 mm in superior/inferior (S/I) direction. The absolute mean compensation error is 1.78 mm radially with a 1.27 mm contribution in the S/I direction. Regions of high total error may provide insight into features predicting groups of patients with larger or smaller total errors.

For each x-ray pair acquired, system logfiles report the prediction error, the difference between the measured and predicted fiducial positions, and the delivery error, which is an estimate of the statistical error in the model overcoming the latency between x-ray acquisition and robotic repositioning. The total error was calculated at the time of each x-ray pair, for the number of treatment fractions and the number of patients, giving the average respiratory motion compensation error in three dimensions. The 99{sup th} percentile for the total radial error is 3.85 mm, with the highest contribution of 2.79 mm in superior/inferior (S/I) direction. The absolute mean compensation error is 1.78 mm radially with a 1.27 mm contribution in the S/I direction. Regions of high total error may provide insight into features predicting groups of patients with larger or smaller total errors.

    Objective: To study the radiological features of severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease so as to make early diagnosis and treatment. We also intend to find the mechanism of these complications. Methods: A total of 9 pediatric cases with severe respiratory complications during cardiac catheterizations were included in the study. The clinical manifestations, radiological features, and corresponding treatments were reviewed. Results: Most of the cases had severe hypoxia, with 6 cases presenting with bradycardia. Opacification of two lung fields was found in 7 cases, pulmonary edema in 1 case, and atelectasis of the upper right lung in 1 case. With intubation, oxygen inhalation and administration of certain drugs, all cases were saved except 1 case with pulmonary edema. Conclusion: Severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease are emergent and critical, and they often presented with various manifestations. Early diagnosis and correct treatment are the key to successful salvage. (authors)

    Full Text Available Inhalations (inhalation of medicinal substances are one of the effective ways to treat upper respiratory tract diseases and colds. Inhalation therapy is used to treat rhinitis, sinusitis, tonsillitis, pharyngitis, laryngitis, bronchitis and pneumonia, which can be complications of acute respiratory viral infections. The main rules of inhalation are as follows to conduct the procedure better after 1.5 hours after eating; clothes should not impede breathing; the procedure can be carried out only while sitting or standing; solution for the inhaler for treatment of bronchitis should be fresh; it is necessary to strictly keep the prescribed dosage; the time of the procedure should also be respected — usually it is from 1 to 4 minutes, sometimes for adults up to 10 minutes, for children the inhalation period is shorter — 1–2 minutes. Contraindications to inhalation are body temperature above 37.5 degrees; propensity to nasal blee­ding in a patient; propensity to increased arterial pressure, with cardiovascular failure; purulent inflammation of the tonsils; respiratory failure. The procedure should be stopped immediately in case of appearance of adverse symptoms such as shortness of breath, dizziness, difficulty in breathing. Therefore, inhalations must be prescribed by a doctor after examination of a patient. During inhalations in rhinitis, you should try to inhale the vapor through the nose. For effective treatment of rhinitis, inhalations from conife­rous plants are very suitable: fir, pine, juniper, larch, from steamed dried chamomile flowers, mint, and blackberry leaves. Honey inhalations can be used for the treatment of acute and chronic diseases of the upper respiratory tract (tonsillitis, pharyngitis, laryngitis and tracheitis. Medical herbal inhalation for children should be carried out from the age of two years. This must be done under the constant supervision of an adult. Leaves of coniferous trees: pine, fir, if or juniper, cedar

  13. The impact of respiratory motion and treatment technique on stereotactic body radiation therapy for liver cancer

    Wu, Q. Jackie; Thongphiew, Danthai; Wang Zhiheng; Chankong, Vira; Yin Fangfang

    2008-01-01

    Stereotactic body radiation therapy (SBRT), which delivers a much higher fractional dose than conventional treatment in only a few fractions, is an effective treatment for liver metastases. For patients who are treated under free-breathing conditions, however, respiration-induced tumor motion in the liver is a concern. Limited clinical information is available related to the impact of tumor motion and treatment technique on the dosimetric consequences. This study evaluated the dosimetric deviations between planned and delivered SBRT dose in the presence of tumor motion for three delivery techniques: three-dimensional conformal static beams (3DCRT), dynamic conformal arc (DARC), and intensity-modulated radiation therapy (IMRT). Five cases treated with SBRT for liver metastases were included in the study, with tumor motions ranging from 0.5 to 1.75 cm. For each case, three different treatment plans were developed using 3DCRT, DARC, and IMRT. The gantry/multileaf collimator (MLC) motion in the DARC plans and the MLC motion in the IMRT plans were synchronized to the patient's respiratory motion. Retrospectively sorted four-dimensional computed tomography image sets were used to determine patient-organ motion and to calculate the dose delivered during each respiratory phase. Deformable registration, using thin-plate-spline models, was performed to encode the tumor motion and deformation and to register the dose-per-phase to the reference phase images. The different dose distributions resulting from the different delivery techniques and motion ranges were compared to assess the effect of organ motion on dose delivery. Voxel dose variations occurred mostly in the high gradient regions, typically between the target volume and normal tissues, with a maximum variation up to 20%. The greatest CTV variation of all the plans was seen in the IMRT technique with the largest motion range (D99: -8.9%, D95: -8.3%, and D90: -6.3%). The greatest variation for all 3DCRT plans was less

  14. Oral cancer. The importance of early diagnosis and treatment.

    Sciubba, J J

    2001-01-01

    Oral cancer is an important health issue. The WHO predicts a continuing worldwide increase in the number of patients with oral cancer, extending this trend well into the next several decades. In the US the projected number of new cases of oral and oropharyngeal cancer will exceed 31,000 per year. Mortality due to cancers in this region exceeds the annual death rate is the US caused by either cutaneous melanoma or cervical cancer. Significant agents involved in the etiology of oral cancer in Western countries include sunlight exposure, smoking and alcohol consumption. Use of the areca or betel nut in many cultures is a major etiological factor outside of the USA. Other etiologic factors associated with oral squamous cell carcinoma, but far less significant statistically, include syphilis and sideropenic dysphagia. Recently, strong evidence for an etiological relationship between human papilloma virus and a subset of head and neck cancers has been noted. It is generally accepted that most sporadic tumors are the result of a multi-step process of accumulated genetic alterations. These alterations affect epithelial cell behavior by way of loss of chromosomal heterozygosity which in turn leads to a series of events progressing to the ultimate stage of invasive squamous cell carcinoma. The corresponding genetic alterations are reflected in clinical and microscopic pathology from hyperplasia through invasiveness. A wide range of mucosal alternations fall within the rubric of leukoplakia. Proliferative verrucous leukoplakia represents a relatively new type of leukoplakia that is separate from the more common or less innocuous form of this condition. Erythroplakia is particularly relevant considering its almost certain relationship with dysplasia or invasive carcinoma. Squamous cell carcinoma will develop from antecedent dysplastic oral mucosal lesions if an early diagnosis has not been made and treatment given. Early diagnosis within stages I and II correspond to a vastly

    Full Text Available The goal of the study: to investigate treatment adherence in respiratory tuberculosis patients depending on the choice of therapy.Subjects and methods: retrospective full-design study. The case histories of adult new tuberculosis cases who were treated in TB Dispensary in 2015 were analyzed. The groups were formed based on the intake of combined drugs with fixed doses (1 tablet contained 60 mg of isoniazid, 120 mg of rifampicin, 300 mg of pyrazinamide, 225 mg of ethambutol, and 20 mg of pyridoxine – Group 1 (n = 38; or separate tablets in the doses as per drug use instructions (isoniazid, rifampicin, pyrazinamide, ethambutol – Group 2 (n = 78. The groups were compatible as per sex, age, and clinical manifestations of tuberculosis. Patients from Group 1 with the weight of 60 kg received 5 tablets and patients from Group 2 received more than 12 tablets. Patients' adherence to treatment was assessed as per regularity of intake and number of doses during the intensive phase of treatment.Results. Patients from Group 1 were regularly taking anti-tuberculosis drugs, while in Group 2 there were interruptions of treatment (7-21 days in 12 (15.4% patients. In Group, the intensive phase increased up to 90.2 ± 30.6 doses and in Group 2 this increase made 131.6 ± 65.4 doses due to late sputum conversion. In Group 1, sputum conversion was achieved during the first month of treatment in 60% of patients; and in Group 2 – in 10% of cases (p = 0.044. The frequency of transaminase elevation as a side effect was higher in Group 1, but it did not result in discontinuation of drugs. Thus, the intake of combined medication with fixed doses improved tuberculosis patients' adherence to treatment.

  16. Importance of computerized tomography for surgical treatment of intracranial hematomas

    Diemath, H.E.

    1982-01-01

    The improved treatment by using computerized tomography (CT) located operating theater and intensive care unit is reported in comparison of 3,382 patients with severe head injuries. By preoperative use of CT the frequency of diagnosed hermatomas was about the same (29.5% before CT; 27.0% with CT) but the preoperative diagnosed multiple hematomas were much more frequent (14.0% resp. 27.0%). The most important advantage however is the saving of time by CT in this localisation by which the chance of survival has increased from 54% to 69%. Without any doubt everywhere in neurotraumatology the CT should be situated as near as possible to the intensive care unit and to the operating theater and should be available 24 hours a day.

  17. The importance of rehabilitation in the treatment of breast cancer

    Elżbieta Kamusińska

    2014-09-01

    Full Text Available Mastectomy due to breast cancer results in many problems and physical dysfunctions related with the constant necessity to protect the upper extremity at the site of the operated breast, and application of a specialist physiotherapeutic procedure. Rehabilitation is an integral part of the process of breast cancer treatment, and its primary goal is the limitation of selected physical, psychological, and social consequences of this cancerous disease. The achievement of rehabilitation goals requires teamwork – the simultaneous solving of problems in various spheres of the patient’s life. This work should be considered as overall care activity concerning a human being according to a holistic approach. A very important element of rehabilitation after mastectomy is to reassure the patient that with the help of specialists she can overcome difficulties, solve her problems, and return to normal daily life.

    Moratalla, Monica Ballesta; Braun, Petra; Fornas, Guillermina Montoliu

    2008-01-01

    Background: Rhabdomyolysis is a common disorder resulting from a large variety of causes. We describe the MRI features and their importance for diagnosis and treatment. Patients and methods: Between 2003 and 2006, four male patients (age range: 25-33 years) with rhabdomyolysis were studied via 1.5 T MRI (GE, Siemens). In all the patients, T1- and T2-weighted sequences with and without fat suppression, short tau inversion recovery (STIR) and gradient-echo sequences were obtained in axial, coronal and sagittal planes. In one patient, contrast material was given. Results: Two patients presented rhabdomyolysis due to drug abuse, one due to intense exercise and the last one due to long unconsciousness with compression of the paravertebral musculature. Two patients had acute kidney failure. The affected muscles showed an increased signal intensity on T2-weighted and STIR sequences and decreased on T1-weighted sequences. In one patient, intramuscular hemorrhage was observed on T1-weighted and gradient-echo sequences. In the patient with kidney failure, a globular swelling of the kidney with alteration of the corticomedullary differentiation on T2-weighted sequences with fat saturation and hypointensity of the renal medulla on T1-weighted contrast enhanced images was found. Discussion: Immediate recognition of rhabdomyolysis is important to prevent late complications. MRI is the method of choice to evaluate the distribution and extension of the affected muscles, especially when fasciotomy is considered for treatment. Even though the MRI findings are non-specific, the sensitivity in the detection of muscle involvement is higher than CT or US

    2008-01-01

    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.

  2. Bone biology in the elderly: clinical importance for fracture treatment

    Rolvien Tim

    2016-12-01

    Full Text Available Age-related bone impairment often leads to fragility fractures in the elderly. Although excellent surgical care is widely provided, diagnosis and treatment of the underlying bone disorder are often not kept in mind. The interplay of the three major bone cells – osteoblasts, osteoclasts, and osteocytes – is normally well regulated via the secretion of messengers to control bone remodeling. Possible imbalances that might occur in the elderly are partly due to age, genetic risk factors, and adverse lifestyle factors but importantly also due to imbalances in calcium homeostasis (mostly due to vitamin D deficiency or hypochlorhydria, which have to be eliminated. Therefore, the cooperation between the trauma surgeon and the osteologist is of major importance to diagnose and treat the respective patients at risk. We propose that any patient suffering from fragility fractures is rigorously screened for osteoporosis and metabolic bone diseases. This includes bone density measurement by dual-energy X-ray absorptiometry, laboratory tests for calcium, phosphate, vitamin D, and bone turnover markers, as well as additional diagnostic modalities if needed. Thereby, most risk factors, including vitamin D deficiency, can be identified and treated while patients who meet the criteria for a specific therapy (i.e. antiresorptive and osteoanabolic receive such. If local health systems succeed to manage this process of secondary fracture prevention, morbidity and mortality of fragility fractures will decline to a minimum level.

  4. Negative-pressure in treatment of persistent post-traumatic subcutaneous emphysema with respiratory failure: Case report and literature review

    Jakov Mihanović

    2018-02-01

    Full Text Available Subcutaneous emphysema may aggravate traumatic pneumothorax treatment, especially when mechanical ventilation is required. Expectative management usually suffices, but when respiratory function is impaired surgical treatment might be indicated. Historically relevant methods are blowhole incisions and placement of various drains, often with related wound complications. Since the first report of negative pressure wound therapy for the treatment of severe subcutaneous emphysema in 2009, only few publications on use of commercially available sets were published. We report on patient injured in a motor vehicle accident who had serial rib fractures and bilateral pneumothorax managed initially in another hospital. Due to respiratory deterioration, haemodynamic instability and renal failure patient was transferred to our Intensive Care Unit. Massive and persistent subcutaneous emphysema despite adequate thoracic drainage with respiratory deterioration and potentially injurious mechanical ventilation with high airway pressures was the indication for active surgical treatment. Negative-pressure wound therapy dressing was applied on typical blowhole incisions which resulted in swift emphysema regression and respiratory improvement. Negative pressure wound therapy for decompression of severe subcutaneous emphysema represents simple, effective and relatively unknown technique that deserves wider attention.

  7. Prevention and treatment of respiratory syncytial virus bronchiolitis and postbronchiolitic wheezing

    Kimpen Jan LL

    2002-06-01

    Full Text Available Abstract Respiratory syncytial virus (RSV is the primary cause of hospitalization for acute respiratory tract illness in general and specifically for bronchiolitis in young children. The link between RSV bronchiolitis and reactive airway disease is not completely understood, even though RSV bronchiolitis is frequently followed by recurrent episodes of wheezing. Therapy with ribavirin does not appear to significantly reduce long-term respiratory outcome of RSV lower respiratory tract infection, and corticosteroid or bronchodilator therapy may possibly improve outcomes only on a short-term basis. No vaccine against RSV is yet available. It is not known whether prophylaxis with RSV intravenous immune globulin or palivizumab can reduce postbronchiolitic wheezing.

  8. Omalizumab: an anti-immunoglobulin E antibody for the treatment of allergic respiratory diseases

    J. Bousquet

    2008-04-01

    Full Text Available Immunoglobulin E (IgE is central to the development of allergic diseases. Cross-linking of cell-bound IgE by the allergen leads to the initiation of the inflammatory cascade. Omalizumab, an anti-IgE antibody, forms complexes with free IgE, thereby inhibiting the allergic reaction before its commencement. A survey of the clinical trials performed on omalizumab indicated that this anti-IgE antibody is efficacious and well tolerated in the treatment of separate and concomitant asthma and rhinitis. In patients with poorly controlled asthma, omalizumab reduced the asthma exacerbation and emergency visit rate, along with improving the quality of life. The improvement in asthma control was associated with a reduction of inhaled and oral corticosteroids. Improved nasal symptom scores and a reduced need for antihistamines were observed in patients with allergic rhinitis. Omalizumab was also proven to be effective as an add-on therapy for concomitant asthma and rhinitis. In conclusion, omalizumab provides an integrated approach for the treatment and management of allergic respiratory diseases.

Methods: Of a total of 393 patients evaluated, we included 227 (146 and 81 active smokers hospitalized for HD and RD, respectively. All participants received smoking cessation treatment during hospitalization and were followed in a cognitive-behavioral smoking cessation program for six months after hospital discharge. Results: There were significant differences between the HD group and the RD group regarding participation in the cognitive-behavioral program after hospital discharge (13.0% vs. 35.8%; p = 0.003; smoking cessation at the end of follow-up (29% vs. 31%; p < 0.001; and the use of nicotine replacement therapy (3.4% vs. 33.3%; p < 0.001. No differences were found between the HD group and the RD group regarding the use of bupropion (11.0% vs. 12.3%; p = 0.92. Varenicline was used by only 0.7% of the patients in the HD group. Conclusions: In our sample, smoking cessation rates at six months after hospital discharge were higher among the patients with RD than among those with HD, as were treatment adherence rates. The implementation of smoking cessation programs for hospitalized patients with different diseases, delivered by the health care teams that treat these patients, is necessary for greater effectiveness in smoking cessation.

    2016-08-01

    The postoperative course of preterm babies undergoing surgical closure of a patent ductus arteriosus (PDA) is often complicated by postligation cardiac syndrome (PLCS). Despite targeted milrinone prophylaxis, some infants continue to experience postoperative respiratory deterioration. Our objective is to describe the immediate postoperative course and identify risk factors for respiratory instability when preterm infants undergoing PDA ligation are managed with targeted milrinone treatment. A retrospective review of a cohort of infants undergoing PDA ligation between January, 2010 and August, 2013 was conducted. All infants had a targeted neonatal echocardiogram performed 1 hour after surgery. Infants received prophylactic milrinone treatment if the left ventricular output was <200 mL/kg/min. The primary outcome measure was the development of respiratory instability within 24 hours of surgery. Multivariable logistic regression was performed to identify predictors of respiratory instability. Eighty-six infants with a median gestational age of 25 weeks (interquartile range [IQR], 24-26) and a birth weight of 740 g (IQR, 640-853) were included in this study. Forty-nine (57.0%) received milrinone prophylaxis. There were 44 (51.2%) infants who developed oxygenation or ventilation failure, and 7 (8.1%) neonates developed PLCS. Infants with longer isovolumic relaxation time (IVRT ≥30 milliseconds) were more likely to develop either oxygenation or ventilation failure. Although the incidence of PLCS has declined after the introduction of targeted milrinone prophylaxis, many preterm infants continue to develop respiratory instability after surgical ligation. In this population, diastolic dysfunction manifested by prolonged IVRT could be associated with an adverse postoperative respiratory course.

    2009-01-01

    To evaluate a community education program about treatment of acute respiratory infection (ARI). First, community case definitions for severe and mild ARI were developed. The intervention was then evaluated using a controlled before-and-after design. Household surveys collected data about ARI treatment in 20 clusters, each based around a school and health facility. Treatment indicators included percentages of cases attending health facilities and receiving antibiotics. The intervention consisted of an education program in schools culminating in street theater performances, discussions with mothers after performances and training for community leaders and drug retailers by paramedics. The intervention was conducted in mid-2003. Indicators were measured before the intervention in Nov/Dec 2002 and again in Dec 2003/Jan 2004. Two thousand and seven hundred and nineteen households were surveyed and 3654 under-fives were identified, of whom 377 had severe ARI. After implementing the intervention, health post (HP) attendance rose by 13% in under-fives with severe ARI and fell by 9% in under-fives with mild ARI (test of interaction, P = 0.01). Use of prescribed antibiotics increased in under-fives with severe ARI by 21% but only by 1% in under-fives with mild ARI (test of interaction, P = 0.38). Irrespective of ARI severity, the use of non-prescribed antibiotics dropped by 5% (P = 0.002), and consultation with female community health volunteers (FCHVs)and use of safe home remedies increased by 6.7% (P not estimated) and 5.7% (P = 0.008) respectively. The intervention was implemented using local structures and in difficult circumstances, yet had a moderate impact. Thus it has the potential to effect large scale changes in behaviour and merits replication elsewhere.

    2013-12-01

    The aim of this study was to determine whether Saccharomyces boulardii prevents and treats diarrhoea and antibiotic-associated diarrhoea (AAD) in children. A total of 333 hospitalised children with acute lower respiratory tract infection were enrolled in a 2-phase open randomised controlled trial. During the 1st phase, all children received intravenous antibiotics (AB). They were randomly allocated to group A (S. boulardii 500 mg/day + AB, n=167) or group B (AB alone, n=166) and followed for 2 weeks. Diarrhoea was defined as ≥3 loose/watery stools/day during at least 2 days, occurring during treatment and/or up to 2 weeks after AB therapy had stopped. AAD was considered when diarrhoea was caused by Clostridium difficile or when stool cultures remained negative. In the 2nd phase of the study, group B patients who developed diarrhoea were randomly allocated to two sub-groups: group B1 (S. boulardii + oral rehydration solution (ORS)) and group B2 (ORS alone). Data from 283 patients were available for analysis. Diarrhoea prevalence was lower in group A than in group B (11/139 (7.9%) vs. 42/144 (29.2%); relative risk (RR): 0.27, 95% confidence interval (CI): 0.1-0.5). S. boulardii reduced the risk of AAD (6/139 (4.3%) vs. 28/144 (19.4%); RR: 0.22; 95% CI: 0.1-0.5). When group B patients developed diarrhoea (n=42), S. boulardii treatment during 5 days (group B1) resulted in lower stool frequency (Pboulardii were observed. S. boulardii appeared to be effective in the prevention and treatment of diarrhoea and AAD in children treated with intravenous antibiotics.

    Araujo, Laura M L; Rosário Filho, Nelson A; Riedi, Carlos A

    2014-01-01

    this study aimed to prepare a silkworm moth (Bombyx mori) antigenic extract and to perform skin prick tests with this extract in patients with allergic respiratory diseases; to evaluate serum specific immunoglobulin E (IgE) to Bombyx mori using ImmunoCAP® system and to report the frequency of positivity between the two methods and with clinical data. this was a cross-sectional study with 99 children and adolescents diagnosed with asthma and/or allergic rhinitis, who had skin reactivity to at least one of the six aeroallergens tested. Clinical data were evaluated: skin prick tests with Bombyx mori in-house extract, and total and specific IgE analysis using ImmunoCAP® were performed. the frequency of Bombyx mori specific IgE was found to be 52.5% and 60% using the skin prick test and ImmunoCAP®, respectively. An association between a positive skin test for Bombyx mori and the presence of allergic rhinitis, atopic dermatitis, and urticaria was observed, but the same was not true for asthma or allergic conjunctivitis. There was no relation with the severity of asthma or rhinitis symptoms. a high frequency of sensitization to Bombyx mori was observed in a selected population of patients with respiratory allergic diseases in the city of Curitiba, state of Paraná, Brazil. The extract prepared from the wings of this moth species is effective in demonstrating this sensitivity. Copyright © 2013 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

  19. The Respiratory Presentation of Severe Combined Immunodeficiency in Two Mennonite Children at a Tertiary Centre Highlighting the Importance of Recognizing This Pediatric Emergency

    Simon Lam

    2014-01-01

    Full Text Available Severe combined immunodeficiency (SCID is considered to be a pediatric emergency, with respiratory distress being the most common presenting symptom. The authors present two cases of SCID in children <4 months of age with respiratory distress at a tertiary care centre due to a recently described homozygous CD3 delta mutation found only in the Mexican Mennonite population. Failure to respond to broad-spectrum antibiotics prompted investigation for possible SCID. Bronchial alveolar lavage fluid from both patients grew Pneumocystis jiroveci, and flow cytometry revealed absent T cells. The CD3 delta gene is believed to be important in T cell differentiation and maturation. The present article reminds pediatricians and pediatric respirologists that the key to diagnosing SCID is to have a high index of suspicion if there is poor response to conventional therapies.

    Full Text Available Abstract. Recurrent respiratory papillomatosis (RRP is the most frequently occurring tumour of the upper airways associated with a human papilloma virus (HPV. The aim of this study was to reveal some features of systemic and local immunity in RRP, to investigate clinical and immunological efficiency of local treatment with recombinant interferon-α (rIFNα, and to determine clinical and laboratory indications to it’s administration. The study included forty-one patients with confirmed RRP. Their examination included histological examination of papillomas, detection of HPV DNA in papilloma tissues using PCR technique, phenotyping of circulating lymphocytes (CD3+, CD4+, CD8+, CD25+, HLA-DR+ by means of flow cytometry. The levels of IFNγ, TNFα, GM-CSF, IL-2, IL-4, IL-5, IL-10, IL-12, IL-13 in laryngeal secretions were quantified by a multiplex immunoassay. In all cases, we revealed an initially decreased functional activity of Т-lymphocytes, as well as low contents of Т-killer and NK-cells. In laryngeal secretions, increased values of Th1-type-specific cytokines (IFNγ and TNFα were found. Besides that, high levels of local IL-4 were detected thus being typical to alternative Th2-type response. Single inhalations 1000 000 ME of «Interal» or «Roferon» preparations were administered daily (a total of 10-15 millions ME per therapeutic course. Thirteen patients received the treatment after surgery, as an adjuvant therapy, and eleven patients underwent monotherapy. Complete tumor regression of tumors following this monotherapy was observed in 45,5% of the patients, whereas partial regression was registered in 45%. The effect was mostly expressed in frequently recurring juvenile papillomatosis with aggressive course and histological pattern of actively proliferating papilloma. In the patients with complete tumor regression, high initial levels of TNFα and IL-4/IFNг ratios were revealed initially in laryngeal secretions. When rIFNб was

  1. Development and clinical applications of novel antibodies for prevention and treatment of respiratory syncytial virus infection.

    Respiratory syncytial virus (RSV) remains a significant cause of morbidity and mortality in infants and young children, immunocompromised patients and the elderly. Despite the high disease burden, an effective and safe vaccine is lacking, although several candidates are currently in development. Current treatment for RSV infection remains largely supportive and RSV-specific options for prophylaxis are limited to palivizumab. In the past few years, novel therapeutic options including nanobodies, polyclonal and monoclonal antibodies have emerged and there are several products in preclinical and Phase-I, -II or -III clinical trials. The major target for antiviral drug development is the surface fusion (F) glycoprotein, which is crucial for the infectivity and pathogenesis of the virus. Solving the structures of the two conformations of the RSV F protein, the prefusion and postfusion forms, has revolutionized RSV research. It is now known that prefusion F is highly superior in inducing neutralizing antibodies. In this section we will review the stages of development and availability of different antibodies directed against RSV for the prevention and also for treatment of acute RSV infections. Some of these newer anti-RSV agents have shown enhanced potency, are being explored through alternative routes of administration, have improved pharmacokinetic profiles with an extended half-life, and may reduce design and manufacturing costs. Management strategies will require targeting not only high-risk populations (including adults or immunocompromised patients), but also previously healthy children who, in fact, represent the majority of children hospitalized with RSV infection. Following treated patients longitudinally is essential for determining the impact of these strategies on the acute disease as well as their possible long-term benefits on lung morbidity.

  3. Glutaric aciduria type 1--importance of early diagnosis and treatment.

    Afroze, Bushra; Yunus, Zabedah Mohammad

    2014-05-01

    Glutaric aciduria type 1 is a rare inherited organic academia. Untreated patients characteristically develop dystonia secondary to striatal injury during early childhood, which results in high morbidity and mortality. In patients diagnosed during neonatal period, striatal injury can be prevented by metabolic treatment including low lysine diet, carnitine supplementation and aggressive emergency treatment during acute episode of inter current illnesses. However, after the onset of neurological damage initiation of treatment is generally not effective. Therefore; glutaric aciduria type 1 is included in newborn screening panel for inherited metabolic diseases in many countries. We describe two children in a family with glutaric aciduria type 1 and their different long term outcomes. The first child was diagnosed late leading to severe neurological damage. The second child was diagnosed in the neonatal period as a result of selective high-risk screening and was treated appropriately giving a normal growth.

  4. Proton facility economics: the importance of "simple" treatments.

    Johnstone, Peter A S; Kerstiens, John; Richard, Helsper

    2012-08-01

    Given the cost and debt incurred to build a modern proton facility, impetus exists to minimize treatment of patients with complex setups because of their slower throughput. The aim of this study was to determine how many "simple" cases are necessary given different patient loads simply to recoup construction costs and debt service, without beginning to cover salaries, utilities, beam costs, and so on. Simple cases are ones that can be performed quickly because of an easy setup for the patient or because the patient is to receive treatment to just one or two fields. A "standard" construction cost and debt for 1, 3, and 4 gantry facilities were calculated from public documents of facilities built in the United States, with 100% of the construction funded through standard 15-year financing at 5% interest. Clinical best case (that each room was completely scheduled with patients over a 14-hour workday) was assumed, and a statistical analysis was modeled with debt, case mix, and payer mix moving independently. Treatment times and reimbursement data from the investigators' facility for varying complexities of patients were extrapolated for varying numbers treated daily. Revenue assumptions of $X per treatment were assumed both for pediatric cases (a mix of Medicaid and private payer) and state Medicare simple case rates. Private payer reimbursement averages $1.75X per treatment. The number of simple patients required daily to cover construction and debt service costs was then derived. A single gantry treating only complex or pediatric patients would need to apply 85% of its treatment slots simply to service debt. However, that same room could cover its debt treating 4 hours of simple patients, thus opening more slots for complex and pediatric patients. A 3-gantry facility treating only complex and pediatric cases would not have enough treatment slots to recoup construction and debt service costs at all. For a 4-gantry center, focusing on complex and pediatric cases alone

  5. Reduction in non-protein respiratory quotient is related to overall survival after hepatocellular carcinoma treatment.

    Masaya Saito

    Full Text Available BACKGROUND: Transcatheter arterial chemoembolization (TACE is an effective treatment for hepatocellular carcinoma (HCC that can occasionally lead to the shortening of life expectancy. We aimed to make a new and more accurate prognostic model taking into account the course of disease after TACE. METHODOLOGY/PRINCIPAL FINDINGS: We performed a prospective cohort study involving 100 HCC patients who underwent TACE at Kobe University Hospital. Indirect calorimetry and blood biochemical examinations were performed before and 7 days after TACE. Time-dependent and time-fixed factors associated with 1-year mortality after TACE were assessed by multivariate analyses. A predictive model of 1-year mortality was established by the combination of odds ratios of these factors. Multivariate analyses showed that the ratio of non-protein respiratory quotient (npRQ (7 days after/before TACE and Cancer of Liver Italian Program (CLIP score were independent factors of 1-year mortality after TACE (p = 0.014 and 0.013, respectively. Patient-specific 1-year mortality risk scores can be calculated by summarizing the individual risk scores and looking up the patient-specific risk on the graph. CONCLUSIONS: The short-term reduction of npRQ was a time-dependent prognostic factor associated with overall survival in HCC patients undergoing TACE. CLIP score was a time-fixed prognostic factor associated with overall survival. Using the prediction model, which consists of the combination of time-dependent (npRQ ratio and time-fixed (CLIP score prognostic factors, 1-year mortality risk after TACE would be better estimated by taking into account changes during the course of disease.

    When to extubate the endotracheal tube is controversial in patients with depressed mental status. The use of the Glasgow Coma Scale (GCS) with score 8 or above as a criterion for extubation by many investigators is questionable. A total of 133 consecutive patients (M/F: 86/47; age: 71 ± 17 years) admitted to the respiratory care center (RCC) of the hospital were enrolled. The effects of GCS score on the outcomes and weaning rate of the patients were evaluated. The mortality rate was significantly higher in patients with a GCS scoretracheostomy was significantly higher than that in patients without tracheostomy (GCS and dGCS: 94.4% vs. 38.5%, p = 0.001). However, tracheostomy in patients with a high GCS (GCS score ≥ 7T or dGCS score ≥ 10) did not lead to a higher success rate of weaning. In multivariable analysis, tracheostomy was still an independent determinant of successful weaning in patients with low GCS. Tracheostomy increases the success rate of weaning in patients with low GCS, but not in patients with high GCS. Mental status graded by GCS did affect the outcomes in patients with conscious disturbance in the RCC. The low tracheostomy rate in patients with low GCS affected the rate of successful weaning, which might have contributed to the higher mortality rate in patients with low GCS in the RCC.

  9. [Important epidemiological features of the treatment of type 2 diabetes].

    Seguí Díaz, M

    2014-07-01

    According to the various clinical practice guidelines, the recommendations for the treatment of type 2 diabetes are well-established, thus leading to homogenization of clinical practice and avoiding variability. However, it is well known that, depending on factors such as effectiveness, physiopathology, cost, adverse effects, preferences, and comorbidities, each patient will, in the long-term, receive different treatment of type 2 diabetes. The consensus document published last year and approved by the American Diabetes Association and the European Association for the Study of Diabetes recommends distinct targets for each patient with type 2 diabetes and argues for the individualization of the management and treatment of this disease. In other words, the document advocates a patient-centered approach, in which the various therapeutic alternatives are related mainly to distinct physiopathological factors, adverse effects, and the patient's comorbidities, as well as the patient's preferences.

  11. TWO CASES OF TYPE II RESPIRATORY FAILURE IN COPD TREATED IN KATURI MEDICAL COLLEGE HOSPITAL, GUNTUR AND AN OVERVIEW OF TREATMENT OF ACUTE EXACERBATION AND RESPIRATORY FAILURE

    Ramakrishna

    2015-04-01

    Full Text Available Treatment of Type II Respiratory Failure in a COPD patient is a difficult task for the ICU and Pulmonary physician. Multi factorial and multi - disciplinary approach is required . Our experience of two cases treated recently in Katuri medical College Hospita l have common features. One is a male of 54 years age and the other is a female of similar age. Both of them were obese and were nonsmokers. Both were poor and could not afford any ICU treatment on their own. Both were rescued by State sponsored Arogyasree programme. Both of them had the advantage of support from their families. Aided by Arogyasree programme, dedicated staff of ICU, Pulmonology, ENT departments , timely interventions with electrolyte balance, balanced antibiotic therapy, Noninvasive and inva sive ventilator strategies, Nutritional support, Blood transfusions, Timely Tracheostomy and excellent nursing care and drug administration in ICU both patients recovered back to normalcy . Initially both required home oxygen therapy and both were subsequen tly seen maintaining normal oxygenation status even without oxygen causing happiness to family members and the treating physicians

    In breast cancer treatment, intensity-modulated radiation therapy (IMRT) can be utilized to deliver more homogeneous dose to target tissues to minimize the cosmetic impact. We have investigated the effect of the respiratory cycle and radiation beam-on timing on the dose distribution in free-breathing dynamic breast IMRT treatment. Six patients with early stage cancer of the left breast were included in this study. A helical computed tomography (CT) scan was acquired for treatment planning. A four-dimensional computed tomography (4D CT) scan was obtained right after the helical CT scan with little or no setup uncertainty to simulate patient respiratory motion. After optimizing based on the helical CT scan, the sliding-window dynamic multileaf collimator (DMLC) leaf sequence was segmented into multiple sections that corresponded to various respiratory phases per respiratory cycle and radiation beam-on timing. The segmented DMLC leaf sections were grouped according to respiratory phases and superimposed over the radiation fields of corresponding 4D CT image set. Dose calculation was then performed for each phase of the 4D CT scan. The total dose distribution was computed by accumulating the contribution of dose from each phase to every voxel in the region of interest. This was tracked by a deformable registration program throughout all of the respiratory phases of the 4D CT scan. A dose heterogeneity index, defined as the ratio between (D 20 -D 80 ) and the prescription dose, was introduced to numerically illustrate the impact of respiratory motion on the dose distribution of treatment volume. A respiratory cycle range of 4-8 s and randomly distributed beam-on timing were assigned to simulate the patient respiratory motion during the free-breathing treatment. The results showed that the respiratory cycle period and radiation beam-on timing presented limited impact on the target dose coverage and slightly increased the target dose heterogeneity. This motion impact

    The use of complementary medicines is large and growing in both the United States and Europe. To compare the effects of a complex homeopathic preparation (Engystol; Heel GmbH, Baden-Baden, Germany) with those of conventional therapies with antihistamines, antitussives, and nonsteroidal antiinflammatory drugs on upper respiratory symptoms of the common cold in a setting closely related to everyday clinical practice. Nonrandomized, observational study over a treatment period of maximally two weeks. Eighty-five general and homeopathic practices in Germany. Three hundred ninety-seven patients with upper respiratory symptoms of the common cold. Engystol-based therapy or common over-the-counter treatments for the common cold. Patients receiving this homeopathic treatment were allowed other short-term medications, but long-term use of analgesics, antibiotics, and antiinflammatory agents was not permitted. Patients were allowed nonpharmacological therapies such as vitamins, thermotherapies, and others. The effects of treatment were evaluated on the variables fatigue, sensation of illness, chill/tremor, aching joints, overall severity of illness, sum of all clinical variables, temperature, and time to symptomatic improvement. Both treatment regimens provided significant symptomatic relief, and this homeopathic treatment was noninferior in a noninferiority analysis.

    Globally, solid fuels are used by about 3 billion people for cooking and a smaller number use kerosene. These fuels have been associated with acute lower respiratory infection (ALRI) in children. Previous work in Bhaktapur, Nepal, showed comparable relationships of biomass and kerosene cooking fuels with ALRI in young children, compared to those using electricity for cooking. We examine the relationship of kitchen PM 2.5 concentrations to ALRI in those households. ALRI cases and age-matched controls were enrolled from a cohort of children 2-35 months old. 24-h PM 2.5 was measured once in each participant's kitchen. The main analysis was carried out with conditional logistic regression, with PM 2.5 measures specified both continuously and as quartiles. In the kitchens of 393 cases and 431 controls, quartiles of increasing PM 2.5 concentration were associated with a monotonic increase in odds ratios (OR): 1.51 (95% CI: 1.00, 2.27), 2.22 (1.47, 3.34), 2.48 (1.63, 3.77), for the 3 highest exposure quartiles. The general kitchen concentration-response shape across all stoves was supralinear. There was evidence for increased risk with biomass stoves, but the slope for kerosene stoves was steeper, the highest quartile OR being 5.36 (1.35, 21.3). Evidence for increased risk was also found for gas stoves. Results support previous reports that biomass and kerosene cooking fuels are both ALRI risk factors, but suggests that PM 2.5 from kerosene is more potent on a unit mass basis. Further studies with larger sample sizes and preferably using electricity as the baseline fuel are needed. Copyright © 2017 Elsevier Inc. All rights reserved.

  15. Efficacy of a low-cost bubble CPAP system in treatment of respiratory distress in a neonatal ward in Malawi.

    Full Text Available Respiratory failure is a leading cause of neonatal mortality in the developing world. Bubble continuous positive airway pressure (bCPAP is a safe, effective intervention for infants with respiratory distress and is widely used in developed countries. Because of its high cost, bCPAP is not widely utilized in low-resource settings. We evaluated the performance of a new bCPAP system to treat severe respiratory distress in a low resource setting, comparing it to nasal oxygen therapy, the current standard of care.We conducted a non-randomized convenience sample study to test the efficacy of a low-cost bCPAP system treating newborns with severe respiratory distress in the neonatal ward of Queen Elizabeth Central Hospital, in Blantyre, Malawi. Neonates weighing >1,000 g and presenting with severe respiratory distress who fulfilled inclusion criteria received nasal bCPAP if a device was available; if not, they received standard care. Clinical assessments were made during treatment and outcomes compared for the two groups.87 neonates (62 bCPAP, 25 controls were recruited. Survival rate for neonates receiving bCPAP was 71.0% (44/62 compared with 44.0% (11/25 for controls. 65.5% (19/29 of very low birth weight neonates receiving bCPAP survived to discharge compared to 15.4% (1/13 of controls. 64.6% (31/48 of neonates with respiratory distress syndrome (RDS receiving bCPAP survived to discharge, compared to 23.5% (4/17 of controls. 61.5% (16/26 of neonates with sepsis receiving bCPAP survived to discharge, while none of the seven neonates with sepsis in the control group survived.Use of a low-cost bCPAP system to treat neonatal respiratory distress resulted in 27% absolute improvement in survival. The beneficial effect was greater for neonates with very low birth weight, RDS, or sepsis. Implementing appropriate bCPAP devices could reduce neonatal mortality in developing countries.

  17. Respiratory muscle involvement in sarcoidosis.

    Schreiber, Tina; Windisch, Wolfram

    2018-07-01

    In sarcoidosis, muscle involvement is common, but mostly asymptomatic. Currently, little is known about respiratory muscle and diaphragm involvement and function in patients with sarcoidosis. Reduced inspiratory muscle strength and/or a reduced diaphragm function may contribute to exertional dyspnea, fatigue and reduced health-related quality of life. Previous studies using volitional and non-volitional tests demonstrated a reduced inspiratory muscle strength in sarcoidosis compared to control subjects, and also showed that respiratory muscle function may even be significantly impaired in a subset of patients. Areas covered: This review examines the evidence on respiratory muscle involvement and its implications in sarcoidosis with emphasis on pathogenesis, diagnosis and treatment of respiratory muscle dysfunction. The presented evidence was identified by a literature search performed in PubMed and Medline for articles about respiratory and skeletal muscle function in sarcoidosis through to January 2018. Expert commentary: Respiratory muscle involvement in sarcoidosis is an underdiagnosed condition, which may have an important impact on dyspnea and health-related quality of life. Further studies are needed to understand the etiology, pathogenesis and extent of respiratory muscle involvement in sarcoidosis.

  18. Repeated Bronchoscopy - Treatment of Severe Respiratory Failure in a Fire Victim

    Petris Ovidiu Rusalim

    2017-10-01

    Full Text Available A case of respiratory failure in a domestic fire victim presenting with 1-3-degree skin burns on 10% of the total body surface, is reported. Forty-eight hours after admission to hospital, the patient developed severe respiratory failure that did not respond to mechanical ventilation. Severe obstruction of the airway had resulted from secretions and deposits of soot forming bronchial casts. The patient required repeated bronchoscopies to separate and remove the bronchial secretions and soot deposits. An emergency bronchial endoscopic exam was crucial in the patient’s survival and management. The patient was discharged from the hospital after twenty-four days.

  20. Respiratory disorders in paediatric age: orthodontic diagnosis and treatment in dysmetabolic obese children and allergic slim children.

    Favero, L; Arreghini, A; Cocilovo, F; Favero, V

    2013-09-01

    Obesity and allergic susceptibility are worsening problems in the most industrialised countries. With different mechanisms, they both lead to a deterioration of children's life quality because they affect the respiratory system, leading to asthma and respiratory disorders such as mouth breathing and obstructive sleep apnoea. The latter are related to specific types of malocclusions that require an early diagnosis and specific multidisciplinary treatment. The purpose of this work is to show the characteristic signs and symptoms of these disorders in children of the two phenotypes (allergic and slim, obese and dysmetabolic). Intercepting such issues allows both pediatricians and paediatric dentists to refer the child to a multidisciplinary team of specialists able to deal, in a holistic way, with both the physical and behavioural causes, and also with the consequences on systemic and craniofacial development in particular. The literature available on this topic in the years between 1997 and 2011 was reviewed, paying special attention to prevention, paediatric visits, diagnostic tools and treatment options for each of the two conditions. Dysmetabolic obese children and allergic slim children have specific respiratory problems during rest and exercise. Mouth breathing and obstructive sleep apnoea are due to an abnormal craniofacial development and can cause serious systemic problems in adulthood. Intercepting early signs of pathognomonic symptoms of sleep aponea and mouth breathing permits to treat children with an early multidisciplinary approach, and allows for proper physical and psychological development of the child.

  1. Altered pathogenesis of porcine respiratory coronavirus in pigs due to immunosuppressive effects of dexamethasone: implications for corticosteroid use in treatment of severe acute respiratory syndrome coronavirus.

    2007-12-01

    The pathogenesis and optimal treatments for severe acute respiratory syndrome (SARS) are unclear, although corticosteroids were used to reduce lung and systemic inflammation. Because the pulmonary pathology of porcine respiratory coronavirus (PRCV) in pigs resembles SARS, we used PRCV as a model to clarify the effects of the corticosteroid dexamethasone (DEX) on coronavirus (CoV)-induced pneumonia. Conventional weaned pigs (n = 130) in one of four groups (PRCV/phosphate-buffered saline [PBS] [n = 41], PRCV/DEX [n = 41], mock/PBS [n = 23], and mock/DEX [n = 25]) were inoculated intranasally and intratracheally with the ISU-1 strain of PRCV (1 x 10(7) PFU) or cell culture medium. DEX was administered (once daily, 2 mg/kg of body weight/day, intramuscularly) from postinoculation day (PID) 1 to 6. In PRCV/DEX pigs, significantly milder pneumonia, fewer PRCV-positive cells, and lower viral RNA titers were present in lungs early at PID 2; however, at PID 4, 10, and 21, severe bronchointerstitial pneumonia, significantly higher numbers of PRCV-positive cells, and higher viral RNA titers were observed compared to results for PRCV/PBS pigs. Significantly lower numbers of CD2(+), CD3(+), CD4(+), and CD8(+) T cells were also observed in lungs of PRCV/DEX pigs than in those of PRCV/PBS pigs at PID 8 and 10, coincident with fewer gamma interferon (IFN-gamma)-secreting cells in the tracheobronchial lymph nodes as determined by enzyme-linked immunospot assay. Our results confirm that DEX treatment alleviates PRCV pneumonia early (PID 2) in the infection but continued use through PID 6 exacerbates later stages of infection (PID 4, 10, and 21), possibly by decreasing cellular immune responses in the lungs (IFN-gamma-secreting T cells), thereby creating an environment for more-extensive viral replication. These data have potential implications for corticosteroid use with SARS-CoV patients and suggest a precaution against prolonged use based on their unproven efficacy in humans

  2. Respiratory Acid-Base Disorders in the Critical Care Unit.

    Hopper, Kate

    2017-03-01

    The incidence of respiratory acid-base abnormalities in the critical care unit (CCU) is unknown, although respiratory alkalosis is suspected to be common in this population. Abnormal carbon dioxide tension can have many physiologic effects, and changes in Pco 2 may have a significant impact on outcome. Monitoring Pco 2 in CCU patients is an important aspect of critical patient assessment, and identification of respiratory acid-base abnormalities can be valuable as a diagnostic tool. Treatment of respiratory acid-base disorders is largely focused on resolution of the primary disease, although mechanical ventilation may be indicated in cases with severe respiratory acidosis.

  7. Incidence of Changes in Respiration-Induced Tumor Motion and Its Relationship With Respiratory Surrogates During Individual Treatment Fractions

    Malinowski, Kathleen; McAvoy, Thomas J.; George, Rohini; Dietrich, Sonja; D’Souza, Warren D.

    2012-01-01

    Purpose: To determine how frequently (1) tumor motion and (2) the spatial relationship between tumor and respiratory surrogate markers change during a treatment fraction in lung and pancreas cancer patients. Methods and Materials: A Cyberknife Synchrony system radiographically localized the tumor and simultaneously tracked three respiratory surrogate markers fixed to a form-fitting vest. Data in 55 lung and 29 pancreas fractions were divided into successive 10-min blocks. Mean tumor positions and tumor position distributions were compared across 10-min blocks of data. Treatment margins were calculated from both 10 and 30 min of data. Partial least squares (PLS) regression models of tumor positions as a function of external surrogate marker positions were created from the first 10 min of data in each fraction; the incidence of significant PLS model degradation was used to assess changes in the spatial relationship between tumors and surrogate markers. Results: The absolute change in mean tumor position from first to third 10-min blocks was >5 mm in 13% and 7% of lung and pancreas cases, respectively. Superior–inferior and medial–lateral differences in mean tumor position were significantly associated with the lobe of lung. In 61% and 54% of lung and pancreas fractions, respectively, margins calculated from 30 min of data were larger than margins calculated from 10 min of data. The change in treatment margin magnitude for superior–inferior motion was >1 mm in 42% of lung and 45% of pancreas fractions. Significantly increasing tumor position prediction model error (mean ± standard deviation rates of change of 1.6 ± 2.5 mm per 10 min) over 30 min indicated tumor–surrogate relationship changes in 63% of fractions. Conclusions: Both tumor motion and the relationship between tumor and respiratory surrogate displacements change in most treatment fractions for patient in-room time of 30 min.

  9. Use of Respiratory-Correlated Four-Dimensional Computed Tomography to Determine Acceptable Treatment Margins for Locally Advanced Pancreatic Adenocarcinoma

    Goldstein, Seth D.; Ford, Eric C.; Duhon, Mario; McNutt, Todd; Wong, John; Herman, Joseph M.

    2010-01-01

    Purpose: Respiratory-induced excursions of locally advanced pancreatic adenocarcinoma could affect dose delivery. This study quantified tumor motion and evaluated standard treatment margins. Methods and Materials: Respiratory-correlated four-dimensional computed tomography images were obtained on 30 patients with locally advanced pancreatic adenocarcinoma; 15 of whom underwent repeat scanning before cone-down treatment. Treatment planning software was used to contour the gross tumor volume (GTV), bilateral kidneys, and biliary stent. Excursions were calculated according to the centroid of the contoured volumes. Results: The mean ± standard deviation GTV excursion in the superoinferior (SI) direction was 0.55 ± 0.23 cm; an expansion of 1.0 cm adequately accounted for the GTV motion in 97% of locally advanced pancreatic adenocarcinoma patients. Motion GTVs were generated and resulted in a 25% average volume increase compared with the static GTV. Of the 30 patients, 17 had biliary stents. The mean SI stent excursion was 0.84 ± 0.32 cm, significantly greater than the GTV motion. The xiphoid process moved an average of 0.35 ± 0.12 cm, significantly less than the GTV. The mean SI motion of the left and right kidneys was 0.65 ± 0.27 cm and 0.77 ± 0.30 cm, respectively. At repeat scanning, no significant changes were seen in the mean GTV size (p = .8) or excursion (p = .3). Conclusion: These data suggest that an asymmetric expansion of 1.0, 0.7, and 0.6 cm along the respective SI, anteroposterior, and medial-lateral directions is recommended if a respiratory-correlated four-dimensional computed tomography scan is not available to evaluate the tumor motion during treatment planning. Surrogates of tumor motion, such as biliary stents or external markers, should be used with caution.

    The Middle East respiratory syndrome coronavirus (MERS-CoV) causes a severe acute respiratory tract infection with a high fatality rate in humans. Coronaviruses are capable of infecting multiple species and can evolve rapidly through recombination events. Here, we report the complete genomic sequence analysis of a MERS-CoV strain imported to China from South Korea. The imported virus, provisionally named ChinaGD01, belongs to group 3 in clade B in the whole-genome phylogenetic tree and also has a similar tree topology structure in the open reading frame 1a and -b (ORF1ab) gene segment but clusters with group 5 of clade B in the tree constructed using the S gene. Genetic recombination analysis and lineage-specific single-nucleotide polymorphism (SNP) comparison suggest that the imported virus is a recombinant comprising group 3 and group 5 elements. The time-resolved phylogenetic estimation indicates that the recombination event likely occurred in the second half of 2014. Genetic recombination events between group 3 and group 5 of clade B may have implications for the transmissibility of the virus. The recent outbreak of MERS-CoV in South Korea has attracted global media attention due to the speed of spread and onward transmission. Here, we present the complete genome of the first imported MERS-CoV case in China and demonstrate genetic recombination events between group 3 and group 5 of clade B that may have implications for the transmissibility of MERS-CoV.

    During the treatment phase of active pulmonary tuberculosis (PTB), respiratory function impairment is usually restrictive. This may become obstructive, as a PTB-associated airflow obstruction (AFO) or as a later manifestation of underlying COPD. The aim of the study was to examine the potential causes and risks for AFO development in PTB by exploring the aspects of spirometry limitations and clinical implications for the underlying COPD detection, taking into account various confounding factors. Prospective, nest case-control study on 40 new cases of PTB with initial restrictive respiratory function impairment, diagnosed and treated according to the directly observed treatment short course (DOTS) strategy. From all observed patients, 37.5% of them developed AFO upon the completion of PTB treatment, with significantly increased average of forced vital capacity (%) (Ppulmonary tuberculosis lesions (OR 1.01-1.05 for 95% CI; P=0.02) and sputum conversion rate on culture (OR 1.02-1.68 for 95% CI; P=0.04) as the most significant predictors for the risk of AFO development. AFO upon PTB treatment is a common manifestation of underlying COPD, which mostly occurs later, during the reparative processes in active PTB, even in the absence of major risk factors, such as cigarette smoking and biomass fuel dust exposure. Initial spirometry testing in patients with active PTB is not a sufficient and accurate approach in the detection of underlying COPD, which may lead to their further potential health deterioration.

  12. Veno-venous extracorporeal CO2 removal for the treatment of severe respiratory acidosis: pathophysiological and technical considerations.

    2014-06-17

    While non-invasive ventilation aimed at avoiding intubation has become the modality of choice to treat mild to moderate acute respiratory acidosis, many severely acidotic patients (pH respiratory acidosis was only feasible when blood flow rates of 750 to 1000 mL/minute (19Fr catheter) were used. Maximal CO2-elimination was 146.1 ± 22.6 mL/minute, while pH increased from 7.13 ± 0.08 to 7.41 ± 0.07 (blood flow of 1000 mL/minute; sweep gas flow 16 L/minute). Accordingly, a sweep gas flow of 8 L/minute resulted in a maximal CO2-elimination rate of 138.0 ± 16.9 mL/minute. The 14.5Fr catheter allowed a maximum CO2 elimination rate of 77.9 mL/minute, which did not result in the normalization of pH. Veno-venous ECCO2R may serve as a treatment option for severe respiratory acidosis. In this porcine model, ECCO2R was most effective when using blood flow rates ranging between 750 and 1000 mL/minute, while an increase in sweep gas flow from 8 to 16 L/minute had less impact on ECCO2R in this setting.

  13. Respiratory problems in foals.

    Beech, J

    1985-04-01

    Despite major advances in our knowledge and ability to treat respiratory diseases in neonatal foals, neonatal respiratory medicine is still in its infancy. It is hoped that this article may serve as a guideline for diagnosis and treatment. Specific antibiotic regimens and emergency procedures are covered in other articles in this symposium. Because management factors play a critical role in the pathogenesis of respiratory disease, education of clients as to their importance would help both prophylactically and therapeutically. The necessity of very careful monitoring of neonates, which is critical to early detection of disease, should be stressed. As respiratory diseases can be fulminant and rapidly fatal, it is imperative not to delay diagnosis and therapy. Thorough examination and implementation of appropriate diagnostic techniques, as well as prompt early referral to a more sophisticated facility when indicated, would prevent many deaths. Although sophisticated support systems are vital for survival of some of these foals, good basic intensive nursing care combined with selection of appropriate drug therapy very early in the course of the disease is all that many foals require and can significantly improve survival rates.

  14. Neonatal Caffeine Treatment and Respiratory Function at 11 Years in Children under 1,251 g at Birth.

    Doyle, Lex W; Ranganathan, Sarath; Cheong, Jeanie L Y

    2017-11-15

    Caffeine in the newborn period shortens the duration of assisted ventilation and reduces the incidence of bronchopulmonary dysplasia, but its effects on respiratory function in later childhood are unknown. To determine if children born with birth weight less than 1,251 g who were treated with neonatal caffeine had improved respiratory function at 11 years of age compared with children treated with placebo. Children enrolled in the CAP (Caffeine for Apnea of Prematurity) randomized controlled trial and assessed at the Royal Women's Hospital in Melbourne at 11 years of age had expiratory flow rates measured according to the standards of the American Thoracic Society. Values were converted to z-scores predicted for age, height, ethnicity, and sex. Parents completed questionnaires related to their child's respiratory health. A total of 142 children had expiratory flows measured. Expiratory flows were better in the caffeine group, by approximately 0.5 SD for most variables (e.g., FEV 1 ; mean z-score, -1.00 vs. -1.53; mean difference, 0.54; 95% confidence interval, 0.14-0.94; P = 0.008). Fewer children in the caffeine group had values for FVC below the fifth centile (11% vs. 28%; odds ratio, 0.31; 95% confidence interval, 0.12-0.77; P = 0.012). When adjusted for bronchopulmonary dysplasia, the difference in flow rates between groups diminished. Caffeine treatment in the newborn period improves expiratory flow rates in midchildhood, which seems to be achieved by improving respiratory health in the newborn period. Follow-up lung function testing in adulthood is vital for these individuals. Future placebo-controlled randomized trials of neonatal caffeine are unlikely. Clinical trial registered with www.clinicaltrials.gov (NCT00182312).

Based on a prespecified Cochrane protocol, we did a systematic literature search on the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase, and pooled individual patient data from trials in which patients with respiratory infections were randomly assigned to receive antibiotics based on procalcitonin concentrations (procalcitonin-guided group) or control. The coprimary endpoints were 30-day mortality and setting-specific treatment failure. Secondary endpoints were antibiotic use, length of stay, and antibiotic side-effects. We identified 990 records from the literature search, of which 71 articles were assessed for eligibility after exclusion of 919 records. We collected data on 6708 patients from 26 eligible trials in 12 countries. Mortality at 30 days was significantly lower in procalcitonin-guided patients than in control patients (286 [9%] deaths in 3336 procalcitonin-guided patients vs 336 [10%] in 3372 controls; adjusted odds ratio [OR] 0·83 [95% CI 0·70 to 0·99], p=0·037). This mortality benefit was similar across subgroups by setting and type of infection (p interactions >0·05), although mortality was very low in primary care and in patients with acute bronchitis. Procalcitonin guidance was also associated with a 2·4-day reduction in antibiotic exposure (5·7 vs 8·1 days [95% CI -2·71 to -2·15], pacute respiratory infections reduces antibiotic exposure and side-effects, and improves survival. Widespread implementation of procalcitonin protocols in patients with acute respiratory infections thus has the potential to improve antibiotic

    To investigate the significance and effect of pressure controlled ventilation (PCV) as well as volume controlled ventilation (VCV) by lung protective strategy on respiratory mechanics, blood gas analysis and hemodynamics in patients with acute respiratory distress syndrome (ARDS). Fifty patients with ARDS were randomly divided into PCV and VCV groups with permissive hypercapnia and open lung strategy. Changes in respiratory mechanics, blood gas analysis and hemodynamics were compared between two groups. Peak inspiration pressure (PIP) in PCV group was significantly lower than that in VCV group, while mean pressure of airway (MPaw) was significantly higher than that in VCV after 24 hours mechanical ventilation. After 24 hours mechanical ventilation, there were higher central venous pressure (CVP) and slower heart rate (HR) in two groups, CVP was significantly higher in VCV compared with PCV, and PCV group had slower HR than VCV group, the two groups had no differences in mean blood pressure (MBP) at various intervals. All patients showed no ventilator-induced lung injury. Arterial blood oxygenations were obviously improved in two groups after 24 hours mechanical ventilation, PCV group had better partial pressure of oxygen in artery (PaO2) than VCV group. Both PCV and VCV can improve arterial blood oxygenations, prevent ventilator-induced lung injury, and have less disturbance in hemodynamic parameters. PCV with lung protective ventilatory strategy should be early use for patients with ARDS.

    Full Text Available Background: Respiratory infections are a frequent cause of fever in neutropenic patients, whereas respiratory viral infections are not frequently considered as a diagnosis, which causes high morbidity and mortality in these patients. Materials and Methods: This prospective study was performed on 36 patients with neutropenia who admitted to hospital were eligible for inclusion with fever (single temperature of >38.3°C or a sustained temperature of >38°C for more than 1 h, upper and lower respiratory symptoms. Sampling was performed from the throat of the patient by the sterile swab. All materials were analyzed by quantitative real-time multiplex polymerase chain reaction covering the following viruses; influenza, parainfluenza virus (PIV, rhinovirus (RV, human metapneumovirus, and respiratory syncytial virus (RSV. Results: RV was the most frequently detected virus and then RSV was the most. PIV was not present in any of the tested samples. Furthermore, no substantial differences in the distribution of specific viral species were observed based on age, sex, neutropenia duration, hematological disorder, and respiratory tract symptoms and signs (P > 0.05. Conclusion: Our prospective study supports the hypothesis that respiratory viruses play an important role in the development of neutropenic fever, and thus has the potential to individualize infection treatment and to reduce the extensive use of antibiotics in immunocompromised patients with neutropenia.

    irregular respiration. Limitations from x-ray tube heating in our current CT unit restrict the length of the scan region to 9 cm for the RCCT settings used, though this will not be a limitation for a multislice scanner. RCCT offers an alternative to the current method of respiration-triggered axial scans. Multiple phases of respiration are imaged with RCCT in approximately the same scanning time required to image a single phase with a triggered axial scan. RCCT scans can be used in connection with respiratory-gated treatment to identify the patient-specific phase of minimum tumor motion, determine residual tumor motion within the gate interval, and compare treatment plans at different phases

    2008-01-01

    Purpose: To use probability density function (PDF) to model motion effects and incorporate this information into treatment planning for lung cancers. Material and methods: PDFs were calculated from the respiratory motion traces of 10 patients. Motion effects were evaluated by convolving static dose distributions with various PDFs. Based on a differential dose prescription with relatively lower dose to the clinical target volume (CTV) than to the gross tumor volume (GTV), two approaches were proposed to incorporate PDFs into treatment planning. The first approach uses the GTV-based internal target volume (ITV) as the planning target volume (PTV) to ensure full dose to the GTV, and utilizes the motion-induced dose gradient to cover the CTV. The second approach employs an inhomogeneous static dose distribution within a minimized PTV to best match the prescription dose gradient. Results: Motion effects on dose distributions were minimal in the anterior-posterior (AP) and lateral directions: a 10-mm motion only induced about 3% of dose reduction in the peripheral target region. The motion effect was remarkable in the cranial-caudal direction. It varied with the motion amplitude, but tended to be similar for various respiratory patterns. For the first approach, a 10-15 mm motion would adequately cover the CTV (presumed to be 60-70% of the GTV dose) without employing the CTV in planning. For motions 15-mm. An example of inhomogeneous static dose distribution in a reduced PTV was given, and it showed significant dose reduction in the normal tissue without compromising target coverage. Conclusions: Respiratory motion-induced dose gradient can be utilized to cover the CTV and minimize the lung dose without the need for more sophisticated technologies

  2. Anaerobic bacteria in upper respiratory tract and head and neck infections: microbiology and treatment.

    2012-04-01

    Anaerobes are the predominant components of oropharyngeal mucous membranes bacterial flora, and are therefore a common cause of bacterial infections of endogenous origin of upper respiratory tract and head and neck. This review summarizes the aerobic and anaerobic microbiology and antimicrobials therapy of these infections. These include acute and chronic otitis media, mastoiditis and sinusitis, pharyngo-tonsillitis, peritonsillar, retropharyngeal and parapharyngeal abscesses, suppurative thyroiditis, cervical lymphadenitis, parotitis, siliadenitis, and deep neck infections including Lemierre Syndrome. The recovery from these infections depends on prompt and proper medical and when indicated also surgical management. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Rib fracture is a common injury and can result in pain during respiration. Conservative treatment of rib fracture is applied via mechanical ventilation. However, ventilator-associated complications frequently occur. Surgical fixation is another approach to treat rib fractures. Unfortunately, this surgical treatment is still not completely defined. Past studies have evaluated the biomechanics of the rib cage during respiration using a finite element method, but only intact conditions were modelled. Thus, the purpose of this study was to develop a realistic numerical model of the human rib cage and to analyse the biomechanical performance of intact, injured and treated rib cages. Three-dimensional finite element models of the human rib cage were developed. Respiratory movement of the human rib cage was simulated to evaluate the strengths and limitations of different scenarios. The results show that a realistic human respiratory movement can be simulated and the predicted results were closely related to previous study (correlation coefficient>0.92). Fixation of two fractured ribs significantly decreased the fixation index (191%) compared to the injured model. This fixation may provide adequate fixation stability as well as reveal lower bone stress and implant stress compared with the fixation of three or more fractured ribs.

    Obesity has become an important public health problem worldwide that disproportionally affects the underserved. Obesity has been associated with many diseases and unfortunately has not spared the respiratory system. Specifically, the prevalence of common respiratory problems, such as asthma and obstructive sleep apnoea, is higher in obese children. Further, the treatment outcomes of these frequent conditions is also worse in obese children compared to lean controls. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Background The aim of this study was to assess the effectiveness of homeopathy compared to conventional treatment in acute respiratory and ear complaints in a primary care setting. Methods The study was designed as an international, multi-centre, comparative cohort study of non-randomised design. Patients, presenting themselves with at least one chief complaint: acute (≤ 7 days) runny nose, sore throat, ear pain, sinus pain or cough, were recruited at 57 primary care practices in Austria (8), Germany (8), the Netherlands (7), Russia (6), Spain (6), Ukraine (4), United Kingdom (10) and the USA (8) and given either homeopathic or conventional treatment. Therapy outcome was measured by using the response rate, defined as the proportion of patients experiencing 'complete recovery' or 'major improvement' in each treatment group. The primary outcome criterion was the response rate after 14 days of therapy. Results Data of 1,577 patients were evaluated in the full analysis set of which 857 received homeopathic (H) and 720 conventional (C) treatment. The majority of patients in both groups reported their outcome after 14 days of treatment as complete recovery or major improvement (H: 86.9%; C: 86.0%; p = 0.0003 for non-inferiority testing). In the per-protocol set (H: 576 and C: 540 patients) similar results were obtained (H: 87.7%; C: 86.9%; p = 0.0019). Further subgroup analysis of the full analysis set showed no differences of response rates after 14 days in children (H: 88.5%; C: 84.5%) and adults (H: 85.6%; C: 86.6%). The unadjusted odds ratio (OR) of the primary outcome criterion was 1.40 (0.89–2.22) in children and 0.92 (0.63–1.34) in adults. Adjustments for demographic differences at baseline did not significantly alter the OR. The response rates after 7 and 28 days also showed no significant differences between both treatment groups. However, onset of improvement within the first 7 days after treatment was significantly faster upon homeopathic treatment both

    Full Text Available Congenital muscular dystrophy is a distinct group of diseases presenting with weakness in infancy or childhood and no current therapy. One form, MDC1A, is the result of laminin alpha-2 deficiency and results in significant weakness, respiratory insufficiency and early death. Modification of apoptosis is one potential pathway for therapy in these patients.dy(2J mice were treated with vehicle, 0.1 mg/kg or 1 mg/kg of omigapil daily via oral gavage over 17.5 weeks. Untreated age matched BL6 mice were used as controls. Functional, behavioral and histological measurements were collected.dy(2J mice treated with omigapil showed improved respiratory rates compared to vehicle treated dy(2J mice (396 to 402 vs. 371 breaths per minute, p<0.03 and similar to control mice. There were no statistical differences in normalized forelimb grip strength between dy(2J and controls at baseline or after 17.5 weeks and no significant differences seen among the dy(2J treatment groups. At 30-33 weeks of age, dy(2J mice treated with 0.1 mg/kg omigapil showed significantly more movement time and less rest time compared to vehicle treated. dy(2J mice showed normal cardiac systolic function throughout the trial. dy(2J mice had significantly lower hindlimb maximal (p<0.001 and specific force (p<0.002 compared to the control group at the end of the trial. There were no statistically significant differences in maximal or specific force among treatments. dy(2J mice treated with 0.1 mg/kg/day omigapil showed decreased percent fibrosis in both gastrocnemius (p<0.03 and diaphragm (p<0.001 compared to vehicle, and in diaphragm (p<0.013 when compared to 1 mg/kg/day omigapil treated mice. Omigapil treated dy(2J mice demonstrated decreased apoptosis.Omigapil therapy (0.1 mg/kg improved respiratory rate and decreased skeletal and respiratory muscle fibrosis in dy(2J mice. These results support a putative role for the use of omigapil in laminin deficient congenital muscular dystrophy

  7. Doxycycline in the treatment of respiratory tract infections. Results of a pan-European multi-centre trial.

    Pestel, M

    1975-01-01

    In the winter of 1973-4, general practitioners from seven European countries took part in a multi-centre trial of doxycycline in the treatment of infections of the respiratory tract. The carefully designed protocol was observed by all participants. A total of 1,747 patients were admitted to the trial; their ages ranged from 6 years to over 80. The commonest diagnoses (50%) were acute bronchitis and acute exacerbations of chronic bronchitis. On the recommended dosage of 200 mg doxycycline on the first day, followed by 100 mg daily thereafter (though 200 mg could be continued daily in severe cases), 87% of patients achieved good or very good results. Both subjective (pain) and objective (sputum volume and viscosity, temperature, cough) measures showed rapid improvement, usually by the third to fifth days. Side-effects were minimal and mainly gastrointestinal and caused only 4 patients to discontinue treatment. Overall, doxycycline proved its effectiveness and rapidity of action.

  8. Immunostimulation with oral vaccines for prevention and treatment of respiratory tract infections

    Robert Szamborski

    2016-03-01

    Full Text Available The respiratory system is susceptible to unfavourable effects of biological and non-biological factors. In the protection against infectious agents, the immune system plays a crucial role thanks to close cooperation of specific (acquired and non-specific (natural, innate immune mechanisms. A non-specific response actively supports specific response mechanisms. This enables effective protection of our body against infections, both at the stage when pathogens reach the organism and after their penetration into tissues. A stimulation with microbial antigens leads to the activation of specific immunity mechanisms: humoral and cell-mediated responses. In the humoral response, specific immunoglobulins of various classes are involved to protect from recurrent infections. The knowledge of immunity development enables immune system stimulation with pharmaceutical products. The most common immunostimulants are non-specific and specific bacterial vaccines. The main goal of vaccines is the protection of healthy individuals against infections. Conventional prophylactic vaccines are immunogenic products. They contain a combination of extracts of various bacteria, usually ones that are aetiological factors of upper respiratory tract infections. Non-specific vaccines are administered to provoke a specific immune response towards antigens contained in the vaccine. They are bacterial immunostimulants acting mainly by stimulation and mobilisation of host defensive mechanisms. They improve antibacterial serum properties by increasing the level of natural antibodies. If needed, these reactions should be easily stimulated by a pathogen present in nature and should effectively neutralize or limit the disease. In patients who have been treated with a non-specific vaccine, decreased numbers of episodes of respiratory tract infections as well lower antibiotic intake were noted.

    Respiratory syncytial virus (RSV) is an important causative agent of lower respiratory tract infections in infants and elderly individuals. Its fusion (F) protein is critical for virus infection. It is targeted by several investigational antivirals and by palivizumab, a humanized monoclonal antibody used prophylactically in infants considered at high risk of severe RSV disease. ALX-0171 is a trimeric Nanobody that binds the antigenic site II of RSV F protein with subnanomolar affinity. ALX-0171 demonstrated in vitro neutralization superior to that of palivizumab against prototypic RSV subtype A and B strains. Moreover, ALX-0171 completely blocked replication to below the limit of detection for 87% of the viruses tested, whereas palivizumab did so for 18% of the viruses tested at a fixed concentration. Importantly, ALX-0171 was highly effective in reducing both nasal and lung RSV titers when delivered prophylactically or therapeutically directly to the lungs of cotton rats. ALX-0171 represents a potent novel antiviral compound with significant potential to treat RSV-mediated disease. PMID:26438495

    ABSTRACT

    Middle East respiratory syndrome coronavirus (MERS-CoV) causes a highly lethal pulmonary infection with ~35% mortality. The potential for a future pandemic originating from animal reservoirs or health care-associated events is a major public health concern. There are no vaccines or therapeutic agents currently available for MERS-CoV. Using a probe-based single B cell cloning strategy, we have identified and characterized multiple neutralizing monoclonal antibodies (MAbs) specifically binding to the receptor-binding domain (RBD) or S1 (non-RBD) regions from a convalescent MERS-CoV-infected patient and from immunized rhesus macaques. RBD-specific MAbs tended to have greater neutralizing potency than non-RBD S1-specific MAbs. Six RBD-specific and five S1-specific MAbs could be sorted into four RBD and three non-RBD distinct binding patterns, based on competition assays, mapping neutralization escape variants, and structural analysis. We determined cocrystal structures for two MAbs targeting the RBD from different angles and show they can bind the RBD only in the “out” position. We then showed that selected RBD-specific, non-RBD S1-specific, and S2-specific MAbs given prophylactically prevented MERS-CoV replication in lungs and protected mice from lethal challenge. Importantly, combining RBD- and non-RBD MAbs delayed the emergence of escape mutations in a cell-based virus escape assay. These studies identify MAbs targeting different antigenic sites on S that will be useful for defining mechanisms of MERS-CoV neutralization and for developing more effective interventions to prevent or treat MERS-CoV infections.

    IMPORTANCEMERS-CoV causes a highly lethal respiratory infection for which no vaccines or antiviral therapeutic options are currently available. Based on continuing exposure from established reservoirs in dromedary camels and bats, transmission of MERS-CoV into humans and future outbreaks are expected. Using

    Aim of this study was to explore influence of the quadrivalent HPV vaccine (Gardasil(®)) on the immune status of recurrent respiratory papillomatosis (RRP) patients. In retrospective observational study, six RRP patients who received the quadrivalent HPV vaccine and whose HPV seroreactivity was measured were included. Multiplex HPV Serology was used to determine HPV-specific antibodies pre- and post-vaccination. Surgical interventions and patient records were analyzed. Five HPV6 and 1 HPV11 infected patient were included. Mean antibody reactivity against the associated HPV type rose from 1125 median fluorescence intensity (MFI) pre-vaccination to 4690 MFI post-vaccination (p immunological increase can cause decrease in number of surgeries.

    This study will estimate distribution-based minimal important difference (MID) for the Hospital Anxiety and Depression Scale anxiety (HADS-A) and depression (HADS-D) subscales, and the Impact of Event Scale-Revised (IES-R) in survivors of acute respiratory failure (ARF). Secondary analyses of data from two US and three UK studies of ARF survivors (total N=1223). HADS-D and HADS-A were used to assess depression and anxiety symptoms. IES-R assessed post-traumatic stress disorder symptoms. Standard error of measurement, minimal detectable change90, 0.5 standard deviation (S.D.), and 0.2 S.D. were used to estimate MID for the combined sample, by studies, 6- and 12-month follow-ups, country and mental health condition. Overall, MID estimates converged to 2.0-2.5 for the HADS-A, 1.9-2.3 for the HADS-D and 0.17-0.18 for the IES-R. MID estimates were comparable across studies, follow-up, country and mental health condition. Among ARF survivors, 2.0-2.5 is a reasonable range for the MID for both HADS subscales, and 0.2 is reasonable for IES-R. Until anchor-based MIDs for these instruments are available, these distribution-based estimates can help researchers plan future studies and interpret the clinical importance of findings in ARF patient populations.

  13. Effect of Poultry Litter Treatment(R) (PLT(R)) on the development of respiratory tract lesions in broilers.

    Terzich, M; Quarles, C; Goodwin, M A; Brown, J

    1998-01-01

    In previous studies, Poultry Litter Treatment(R) (PLT(R)) was shown to reduce atmospheric ammonia levels and ascites death rates, and produce higher profit value in broiler chickens. The purpose of the present study was to determine the effect of PLT(R) on atmospheric ammonia levels, the development of respiratory tract lesions, and body weight gains in broiler chickens. Data were collected from chicks that were raised in containment conditions that resembled commercial settings. Atmospheric ammonia levels, gross thoracic air sac lesion scores, and the numbers and magnitudes of histopathologic tracheal mucosal injuries were significantly (P = 0.001) reduced in chickens that were raised on PLT(R)-treated litter than in their untreated-litter control counterparts. In addition, mean body weights and lung:body weight ratios were significantly (P broilers that were raised on treated litter. The reductions in respiratory tract lesions among broilers raised on PLT(R)-treated litter were attributed to reductions in atmospheric ammonia levels.

    Respiratory problems are common in athletes of all abilities and can significantly impact upon their health and performance. In this article, we provide an overview of respiratory physiology in athletes. We also discuss the assessment and management of common clinical respiratory conditions as they pertain to athletes, including airways disease, respiratory tract infection and pneumothorax. We focus on providing a pragmatic approach and highlight important caveats for the physician treating respiratory conditions in this highly specific population.

    2012-01-01

    Purpose: The objective of this study was to compare setup precision, respiration-related breast movement and treatment time between prone and supine positions for whole-breast irradiation. Methods and Materials: Ten patients with early-stage breast carcinoma after breast-conserving surgery were treated with prone and supine whole breast-irradiation in a daily alternating schedule. Setup precision was monitored using cone-beam computed tomography (CBCT) imaging. Respiration-related breast movement in the vertical direction was assessed by magnetic sensors. The time needed for patient setup and for the CBCT procedure, the beam time, and the length of the whole treatment slot were also recorded. Results: Random and systematic errors were not significantly different between positions in individual patients for each of the three axes (left-right, longitudinal, and vertical). Respiration-related movement was smaller in prone position, but about 80% of observations showed amplitudes <1 mm in both positions. Treatment slots were longer in prone position (21.2 ± 2.5 min) than in supine position (19.4 ± 0.8 min; p = 0.044). Conclusion: Comparison of setup precision between prone and supine position in the same patient showed no significant differences in random and systematic errors. Respiratory movement was smaller in prone position. The longer treatment slots in prone position can probably be attributed to the higher repositioning need.

    Concentrations of glutathione, a ubiquitous tripeptide with immune enhancing and antioxidant properties, are decreased in the blood and lung epithelial lining fluid of human immunodeficiency virus (HIV) seropositive individuals. Since the lung is the most common site of infection in those who progress to AIDS it is rational to consider whether it is possible to safely augment glutathione levels in the epithelial lining fluid of HIV seropositive individuals, thus potentially improving local host defence. Purified reduced glutathione was delivered by aerosol to HIV seropositive individuals (n = 14) and the glutathione levels in lung epithelial lining fluid were compared before and at one, two, and three hours after aerosol administration. Before treatment total glutathione concentrations in the epithelial lining fluid were approximately 60% of controls. After three days of twice daily doses each of 600 mg reduced glutathione, total glutathione levels in the epithelial lining fluid increased and remained in the normal range for at least three hours after treatment. Strikingly, even though > 95% of the glutathione in the aerosol was in its reduced form, the percentage of oxidised glutathione in epithelial lining fluid increased from 5% before treatment to about 40% three hours after treatment, probably reflecting the use of glutathione as an antioxidant in vivo. No adverse effects were observed. It is feasible and safe to use aerosolised reduced glutathione to augment the deficient glutathione levels of the lower respiratory tract of HIV seropositive individuals. It is rational to evaluate further the efficacy of this tripeptide in improving host defence in HIV seropositive individuals.

    The radiotherapy with beams of photons of the breast cancer in stages I and II is an established technique. The principal risks of the treatment derived from accidental irradiation of pulmonary and cardiac tissue. Several previous studies have indicated that respiratory control techniques involve a benefit in the protection of pulmonary and cardiac volume, and therefore, it would mean a reduction in the risk of mortality and morbidity associated with pulmonary and cardiac damage. The objective of this work is to check if there is a dosimetric benefit of breast with respiratory control treatments, such as reflects the literature. (Author)

  18. Prone positioning ventilation for treatment of acute lung injury and acute respiratory distress syndrome.

    Lan, Mei-juan; He, Xiao-di

    2009-08-01

    Patients who are diagnosed with acute lung injury/acute respiratory distress syndrome (ALI/ARDS) usually have ventilation-perfusion mismatch, severe decrease in lung capacity, and gas exchange abnormalities. Health care workers have implemented various strategies in an attempt to compensate for these pathological alterations. By rotating patients with ALI/ARDS between the supine and prone position, it is possible to achieve a significant improvement in PaO2/FiO2, decrease shunting and therefore improve oxygenation without use of expensive, invasive and experimental procedures. Prone positioning is a safe and effective way to improve ventilation when conventional strategies fail to initiate a patient response. Because a specific cure for ARDS is not available, the goal is to support the patients with therapies that cause the least amount of injury while the lungs have an opportunity to heal. Based on current data, a trial of prone positioning ventilation should be offered to the patients who have ALI/ARDS in the early course of the disease. Published studies exhibit substantial heterogeneity in clinical results, suggesting that an adequately sized study optimizing the duration of proning ventilation strategy is warranted to enable definitive conclusions to be drawn.

    Full Text Available The objective of this study was to compare the efficacy of tulathromycin (TUL with a combination of florfenicol (FFC and long-acting oxytetracycline (LAOTC in the treatment of naturally occurring undifferentiated respiratory diseases in large numbers of sheep. In this study, seven natural outbreaks of sheep pneumonia in Garmsar, Iran were considered. From these outbreaks, 400 sheep exhibiting the signs of respiratory diseases were selected, and the sheep were randomly divided into two equal groups. The first group was treated with a single injection of TUL (dosed at 2.5 mg/kg body weight, and the second group was treated with concurrent injections of FFC (dosed at 40 mg/kg bwt and LAOTC (dosed at 20 mg/kg bwt. In the first group, 186 (93% sheep were found to be cured 5 days after the injection, and 14 (7% sheep needed further treatment, of which 6 (3% were cured, and 8 (4% died. In the second group, 172 (86% sheep were cured after the injections, but 28 (14% sheep needed further treatment, of which 10 (5% were cured, and 18 (9% died. This study revealed that TUL was more efficacious as compared to the combined treatment using FFC and LAOTC. As the first report, this field trial describes the successful treatment of undifferentiated respiratory diseases in large numbers of sheep. Thus, TUL can be used for the treatment of undifferentiated respiratory diseases in sheep. [J Adv Vet Anim Res 2015; 2(3.000: 279-284

  20. Nanotechnology in respiratory medicine.

    Like two sides of the same coin, nanotechnology can be both boon and bane for respiratory medicine. Nanomaterials open new ways in diagnostics and treatment of lung diseases. Nanoparticle based drug delivery systems can help against diseases such as lung cancer, tuberculosis, and pulmonary fibrosis. Moreover, nanoparticles can be loaded with DNA and act as vectors for gene therapy in diseases like cystic fibrosis. Even lung diagnostics with computer tomography (CT) or magnetic resonance imaging (MRI) profits from new nanoparticle based contrast agents. However, the risks of nanotechnology also have to be taken into consideration as engineered nanomaterials resemble natural fine dusts and fibers, which are known to be harmful for the respiratory system in many cases. Recent studies have shown that nanoparticles in the respiratory tract can influence the immune system, can create oxidative stress and even cause genotoxicity. Another important aspect to assess the safety of nanotechnology based products is the absorption of nanoparticles. It was demonstrated that the amount of pulmonary nanoparticle uptake not only depends on physical and chemical nanoparticle characteristics but also on the health status of the organism. The huge diversity in nanotechnology could revolutionize medicine but makes safety assessment a challenging task.

    The respiration is one of the most important factors in respiratory gating radiation therapy (RGRT). We have developed an unique respiratory guidance system using an audio-visual system in order to support and stabilize individual patient's respiration and evaluated the usefulness of this system. Seven patients received the RGRT at our clinic from June 2011 to April 2012. After breathing exercise standard deviations by the superficial contents of respiratory cycles and functions, and analyzed them to examine changes in their breathing before and with the audio-visual system, we measured their spontaneous respiration and their respiration with the audio-visual system respectively. With the measured data, we yielded after the therapy. The PTP (peak to peak) of the standard deviations of the free breathing, the audio guidance system, and the respiratory guidance system were 0.343, 0.148, and 0.078 respectively. The respiratory cycles were 0.645, 0.345, and 0.171 respectively and the superficial contents of the respiratory functions were 2.591, 1.008, and 0.877 respectively. The average values of the differences in the standard deviations among the whole patients at the CT room and therapy room were 0.425 for the PTP, 1.566 for the respiratory cycles, and 3.671 for the respiratory superficial contents. As for the standard deviations before and after the application of the PTP respiratory guidance system, that of the PTP was 0.265, that of the respiratory cycles was 0.474, and that of the respiratory superficial contents. The results of t-test of the values before and after free breathing and the audio-visual guidance system showed that the P-value of the PTP was 0.035, that of the cycles 0.009, and that of the respiratory superficial contents 0.010. The respiratory control could be one of the most important factors in the RGRT which determines the success or failure of a treatment.

  4. Respiratory medicine of reptiles.

    Schumacher, Juergen

    2011-05-01

    Noninfectious and infectious causes have been implicated in the development of respiratory tract disease in reptiles. Treatment modalities in reptiles have to account for species differences in response to therapeutic agents as well as interpretation of diagnostic findings. Data on effective drugs and dosages for the treatment of respiratory diseases are often lacking in reptiles. Recently, advances have been made on the application of advanced imaging modalities, especially computed tomography for the diagnosis and treatment monitoring of reptiles. This article describes common infectious and noninfectious causes of respiratory disease in reptiles, including diagnostic and therapeutic regimen. Copyright © 2011 Elsevier Inc.

  5. Homeopathy in the Age of Antimicrobial Resistance: Is It a Viable Treatment for Upper Respiratory Tract Infections?

    Fixsen, Alison

    2018-05-01

     Acute upper respiratory tract infections (URTIs) and their complications are the most frequent cause of antibiotic prescribing in primary care. With multi-resistant organisms proliferating, appropriate alternative treatments to these conditions are urgently required. Homeopathy presents one solution; however, there are many methods of homeopathic prescribing. This review of the literature considers firstly whether homeopathy offers a viable alternative therapeutic solution for acute URTIs and their complications, and secondly how such homeopathic intervention might take place.  Critical review of post 1994 clinical studies featuring homeopathic treatment of acute URTIs and their complications. Study design, treatment intervention, cohort group, measurement and outcome were considered. Discussion focused on the extent to which homeopathy is used to treat URTIs, rate of improvement and tolerability of the treatment, complications of URTIs, prophylactic and long-term effects, and the use of combination versus single homeopathic remedies.  Multiple peer-reviewed studies were found in which homeopathy had been used to treat URTIs and associated symptoms (cough, pharyngitis, tonsillitis, otitis media, acute sinusitis, etc.). Nine randomised controlled trials (RCTs) and 8 observational/cohort studies were analysed, 7 of which were paediatric studies. Seven RCTs used combination remedies with multiple constituents. Results for homeopathy treatment were positive overall, with faster resolution, reduced use of antibiotics and possible prophylactic and longer-term benefits.  Variations in size, location, cohort and outcome measures make comparisons and generalisations concerning homeopathic clinical trials for URTIs problematic. Nevertheless, study findings suggest at least equivalence between homeopathy and conventional treatment for uncomplicated URTI cases, with fewer adverse events and potentially broader therapeutic outcomes.

    Full Text Available The aim of this study is to compare different modalities used for the treatment of recurrent respiratory papillomatosis (RRP in adults and children in terms of their clinical effect and the duration of benefit. Systematic review of papers was written in the English language and published between 1977 and 2007. Outcomes are number of patients with a clinical response and length of time the response lasted for. We found 28 useful studies. There were 1,045 subjects, 416 children and 339 adults who underwent different treatments for RRP between 1976 and 2007. The methods used consisted of cidofovir, interferon, surgical excision, indole-3-carbinol, acyclovir, mumps vaccine, and photodynamic therapy. 62.5% of patients had a complete response on cidofovir (11 studies, 45.14% on interferon (8 studies, 33.33% on I3C (2 studies, 44.36% after surgery (5 studies, 77.55% after the mumps vaccine (1 study, 100% on acyclovir (1 study, and 9.09% after photodynamic therapy (1 study. The effect of different modalities lasted between 9 and 27 months. In conclusion, it is impossible to reach any reliable conclusions as to which method is the most durable and effective. There is a great need for randomised control multicentre trials on the treatment of RRP, so that reliable results can be produced.

    2015-03-01

    Bovine respiratory disease is an economically important syndrome in the beef industry, and diagnostic accuracy is important for optimal disease management. The objective of this study was to determine whether improving diagnostic sensitivity or specificity was of greater economic value at varied levels of respiratory disease prevalence by using Monte Carlo simulation. Existing literature was used to populate model distributions of published sensitivity, specificity, and performance (ADG, carcass weight, yield grade, quality grade, and mortality risk) differences among calves based on clinical respiratory disease status. Data from multiple cattle feeding operations were used to generate true ranges of respiratory disease prevalence and associated mortality. Input variables were combined into a single model that calculated estimated net returns for animals by diagnostic category (true positive, false positive, false negative, and true negative) based on the prevalence, sensitivity, and specificity for each iteration. Net returns for each diagnostic category were multiplied by the proportion of animals in each diagnostic category to determine group profitability. Apparent prevalence was categorized into low (increasing specificity created more rapid, positive change in net returns than increasing sensitivity. Improvement of diagnostic specificity, perhaps through a confirmatory test interpreted in series or pen-level diagnostics, can increase diagnostic value more than improving sensitivity. Mortality risk was the primary driver for net returns. The results from this study are important for determining future research priorities to analyze diagnostic techniques for bovine respiratory disease and provide a novel way for modeling diagnostic tests.

    Patients with neuromuscular disease are an important group at risk of frequently suffering acute or chronic respiratory failure, which is their main cause of death. They require follow-up by a pediatric respiratory medicine specialist from birth or diagnosis in order to confirm the diagnosis and treat any respiratory complications within a multidisciplinary context. The ventilatory support and the cough assistance have improved the quality of life and long-term survival for many of these patients. In this paper, the authors review the pathophysiology, respiratory function evaluation, sleep disorders, and the most frequent respiratory complications in neuromuscular diseases. The various treatments used, from a respiratory medicine point of view, will be analyzed in a next paper. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana.

    Full Text Available Objective: To analyze the effect of noninvasive positive pressure ventilation combined with aminophylline therapy on blood gas parameters and the degree of inflammation in patients with COPD and type II respiratory failure. Methods: A total of 80 patients with COPD and type Ⅱ respiratory failure were randomly divided into observation group and control group (n=40, control group received symptomatic treatment + aminophylline treatment, observation group received symptomatic treatment + aminophylline + noninvasive positive pressure ventilation treatment, and then differences in blood gas parameters, pulmonary function parameters, hemorheology parameters and inflammatory factor levels were compared between two groups of patients after treatment. Results: Radial artery pH and PO2 values of observation group after treatment were higher than those of control group while PCO2, Cl- and CO2CP values were lower than those of control group; pulmonary function parameters FVC, FEV1, FEF25-75, MMF, PEF and FRC values of observation group after treatment were higher than those of control group; whole blood viscosity (150 s- and 10 s-, plasma viscosity, fibrinogen, erythrocyte aggregation index and erythrocyte rigidity index values in peripheral venous blood of observation group after treatment were lower than those of control group; serum IL-17, IL-33, TREM-1, sICAM-1 and PGE2 levels of observation group after treatment were lower than those of control group. Conclusion: Noninvasive positive pressure ventilation combined with aminophylline can optimize the respiratory function of patients with COPD and type II respiratory failure and improve blood gas parameters and the degree of inflammation.

  19. Importance of local skin treatments during radiotherapy for prevention and treatment of radio-induced epithelitis

    Chargari, C.; Fromantin, I.; Kirova, Y.M.; Chargari, C.

    2009-01-01

    Radio-epithelitis represents a common problem, for which treatments are characterized by a great heterogeneity. The present review of literature focuses on data referenced in Pub med/Medline and published in French/English. Despite a real preclinical rationale, aloe vera and trolamine failed to demonstrate any benefit in the prophylactic settings. In a prospective assessment phase III assessment, Calendula officinalis was shown to be superior to trolamine for the prevention of radio-epithelitis. In the curative settings, sucrafalte failed to demonstrate any benefit. The benefit of dermo-corticoids was suggested in terms of erythema and itching. Promising clinical results are available with hyaluronic acid (M.A. S065D and Ialugen) and silver leaf may reduce the intensity of cutaneous radio-induced side effects. Data from the literature are conflicting, making real the difficulty to adopt from clinical trials any proof-of-principle strategy. Considering these uncertainties, several strategies are allowed. New topics are under investigation. Present data from the literature highlight the need for further trials, in order to propose evidence-based treatments and to harmonize clinical practice.

  20. Digital Tomosynthesis for Respiratory Gated Liver Treatment: Clinical Feasibility for Daily Image Guidance

    Wu, Q. Jackie; Meyer, Jeffrey; Fuller, Jessica; Godfrey, Devon; Wang Zhiheng; Zhang Junan; Yin Fangfang

    2011-01-01

    Purpose: Breath-hold (BH) treatment minimizes internal target volumes (ITV) when treating sites prone to motion. Digital tomosynthesis (DTS) imaging has advantages over cone-beam CT (CBCT) for BH imaging: BH-DTS scan can be completed during a single breath-hold, whereas BH-CBCT is usually acquired by parsing the gantry rotation into multiple BH segments. This study evaluates the localization accuracy of DTS for BH treatment of liver tumors. Methods: Both planning CT and on-board DTS/CBCT images were acquired under BH, using the planning CT BH window as reference. Onboard imaging data sets included two independent DTS orientations (coronal and sagittal), and CBCT images. Soft tissue target positioning was measured by each imaging modality and translated into couch shifts. Performance of the two DTS orientations was evaluated by comparing target positioning with the CBCT benchmark, determined by two observers. Results: Image data sets were collected from thirty-eight treatment fractions (14 patients). Mean differences between the two DTS methods and the CBCT method were <1 mm in all directions (except the lateral direction with sagittal-DTS: 1.2 mm); the standard deviation was in the range of 2.1-3.5 mm for all techniques. The Pearson correlation showed good interobserver agreement for the coronal-DTS (0.72-0.78). The interobserver agreement for the sagittal-DTS was good for the in-plane directions (0.70-0.82), but poor in the out-of-plane direction (lateral, 0.26). Conclusions: BH-DTS may be a simpler alternative to BH-CBCT for onboard soft tissue localization of the liver, although the precision of DTS localization appears to be somewhat lower because of the presence of subtle out-of-plane blur.

Noninvasive respiratory support is considered the optimal method of providing assistance to preterm babies with breathing problems, including nasal continuous positive airway pressure (NCPAP and humidified high flow nasal cannula (HHHFNC. The evidence of the efficacy and safety of HHHFNC used as the primary respiratory support for respiratory distress syndrome (RDS is insufficient in low- and middle-income countries. Objective. To investigate the effect of heated humidified high flow nasal cannula on neonatal respiratory distress syndrome compared with nasal continuous positive airway pressure. Methods. An observational cross-sectional study was performed at a tertiary neonatal intensive care unit in suburban Wenzhou, China, in the period between January 2014 and December 2015. Results. A total of 128 infants were enrolled in the study: 65 in the HHHFNC group and 63 in the NCPAP group. The respiratory support with HHHFNC was similar to that with NCPAP with regard to the primary outcome. There is no significant difference between two groups in secondary outcomes. Comparing with NCPAP group, the incidence of nasal damage was lower in HHHFNC group. Conclusions. HHHFNC is an effective and well-tolerated strategy as the primary treatment of mild to moderate RDS in preterm infants older than 28 weeks of GA.

The majority (90%) of customers sought care from the study pharmacy as their first point of care, while 18 (6%) had previously sought care from another pharmacy and 11 (4%) from a physician for their illness episodes. The most frequently reported reasons for seeking care from pharmacies were ease of access to pharmacies (86%), lower cost (46%), availability of medicine (33%), knowing the drug seller (20%), and convenient hours of operation (19%). The most commonly recommended drugs were acetaminophen dispensed in 76% (228) of visits, antihistamine in 69% (208), and antibiotics in 42% (126). On follow-up, most (86%) of the customers had recovered and 12% had sought further treatment. People with ARI preferred to seek care at pharmacies rather than clinics because these pharmacies were more accessible and provided prompt treatment and medicine with no service charge. We recommend raising awareness among drug sellers on proper dispensing practices and enforcement of laws and regulations for drug sales.

    2011-01-01

    Full Text Available Abstract Background Since the first outbreak of a respiratory illness caused by H1N1 virus in Mexico, several reports have described the need of intensive care or extracorporeal membrane oxygenation (ECMO assistance in young and often healthy patients. Here we describe our experience in H1N1-induced ARDS using both ventilation strategy and ECMO assistance. Methods Following Italian Ministry of Health instructions, an Emergency Service was established at the Careggi Teaching Hospital (Florence, Italy for the novel pandemic influenza. From Sept 09 to Jan 10, all patients admitted to our Intensive Care Unit (ICU of the Emergency Department with ARDS due to H1N1 infection were studied. All ECMO treatments were veno-venous. H1N1 infection was confirmed by PCR assayed on pharyngeal swab, subglottic aspiration and bronchoalveolar lavage. Lung pathology was evaluated daily by lung ultrasound (LUS examination. Results A total of 12 patients were studied: 7 underwent ECMO treatment, and 5 responded to protective mechanical ventilation. Two patients had co-infection by Legionella Pneumophila. One woman was pregnant. In our series, PCR from bronchoalveolar lavage had a 100% sensitivity compared to 75% from pharyngeal swab samples. The routine use of LUS limited the number of chest X-ray examinations and decreased transportation to radiology for CT-scan, increasing patient safety and avoiding the transitory disconnection from ventilator. No major complications occurred during ECMO treatments. In three cases, bleeding from vascular access sites due to heparin infusion required blood transfusions. Overall mortality rate was 8.3%. Conclusions In our experience, early ECMO assistance resulted safe and feasible, considering the life threatening condition, in H1N1-induced ARDS. Lung ultrasound is an effective mean for daily assessment of ARDS patients.

    To define treatment benefit, the Patient Benefit Index contains a weighting of patient-relevant treatment goals using the Patient Needs Questionnaire, which includes a 5-point Likert scale ranging from 0 ("not important at all") to 4 ("very important"). These treatment goals have been assigned to five health dimensions. The importance of each dimension can be derived by averaging the importance ratings on the Likert scales of associated treatment goals. As the use of a Likert scale does not allow for a relative assessment of importance, the objective of this study was to estimate relative importance weights for health dimensions and associated treatment goals in patients with psoriasis by using the analytic hierarchy process and to compare these weights with the weights resulting from the Patient Needs Questionnaire. Furthermore, patients' judgments on the difficulty of the methods were investigated. Dimensions of the Patient Benefit Index and their treatment goals were mapped into a hierarchy of criteria and sub-criteria to develop the analytic hierarchy process questionnaire. Adult patients with psoriasis starting a new anti-psoriatic therapy in the outpatient clinic of the Institute for Health Services Research in Dermatology and Nursing at the University Medical Center Hamburg (Germany) were recruited and completed both methods (analytic hierarchy process, Patient Needs Questionnaire). Ratings of treatment goals on the Likert scales (Patient Needs Questionnaire) were summarized within each dimension to assess the importance of the respective health dimension/criterion. Following the analytic hierarchy process approach, consistency in judgments was assessed using a standardized measurement (consistency ratio). At the analytic hierarchy process level of criteria, 78 of 140 patients achieved the accepted consistency. Using the analytic hierarchy process, the dimension "improvement of physical functioning" was most important, followed by "improvement of social

    The influence of parental socio-economic status on childhood cancer treatment outcome in low-income countries has not been sufficiently investigated. Our study examined this influence and explored parental experiences during cancer treatment of their children in an Indonesian academic hospital. Medical charts of 145 children diagnosed with cancer between 1999 and 2009 were reviewed retrospectively. From October 2011 until January 2012, 40 caretakers were interviewed using semi-structured questionnaires. Of all patients, 48% abandoned treatment, 34% experienced death, 9% had progressive/ relapsed disease, and 9% overall event-free survival. Prosperous patients had better treatment outcome than poor patients (Pfate or God (55%). Causes of cancer were thought to be destiny (35%) or God's punishment (23%). Alternative treatment could (18%) or might (50%) cure cancer. Most parents (95%) would like more information about cancer and treatment. More contact with doctors was desired (98%). Income decreased during treatment (55%). Parents lost employment (48% fathers, 10% mothers), most of whom stated this loss was caused by their child's cancer (84% fathers, 100% mothers). Loss of income led to financial difficulties (63%) and debts (55%). Treatment abandonment was most important reason for treatment failure. Treatment outcome was determined by parental socio-economic status. Childhood cancer survival could improve if financial constraints and provision of information and guidance are better addressed.

  7. Variations observed in the respiratory activity of potato tubers (Solanum tuberosum L.) after a treatment with gamma radiation

    The present work studies the variations in the respiratory activity of irradiated and IPC treated potato tubers during a storage period of five months. By immediate effect of gamma radiation we can observe an increase in the oxygen consumption of the parenchyma in relation with the control tubers, such increase persists even fours months after gamma radiation. The respiratory activity is reduced in the IPC treated tubers. In the tissues cultivated in vitro the respiratory activity increases at the end of the cultivation period, not only in the control tissues but also in the irradiated ones, though this increase is greater in the control tissues.

    Data about anti-malarial drugs prescription practices in Europe and the safety of imported malaria treatments are scanty. In 1999, a French consensus development conference published guidelines for the prevention and treatment of imported P. falciparum malaria. The impact of these guidelines has not been evaluated. To investigate the impact of these guidelines on the prescription of anti-malarials, and to evaluate the incidence of acute drug events (ADEs) leading to discontinuation of treatment. Cross-sectional survey. Members of the medical staff in 14 French infectious and tropical disease wards completed a standardized form for each patient treated for imported malaria in 2001. A propensity score matching technique was used to estimate the risk of ADEs leading to discontinuation of the regimen. In the 474 patients studied, quinine was the first-line anti-malarial most often prescribed. Only 3% of patients received halofantrine. Mefloquine was associated with a RR of 4.9 (95%CI 3.2-7.4, p guidelines have been taken into account. Mefloquine was associated with a substantial risk of discontinuing the treatment because of ADEs. This is a serious limitation for the use of mefloquine in the treatment of out-patients with imported malaria.

  11. [Undernutrition in chronic respiratory diseases].

    Zielonka, Tadeusz M; Hadzik-Błaszczyk, Małgorzata

    2015-01-01

    Respiratory diseases such as asthma, COPD, lung cancer, infections, including also tuberculosis constitute the most frequent diseases in the word. Undernutrition frequently accompanies these diseases. Early diagnosis of malnutrition and implementation of appropriate treatment is very important. A nutritional interview and anthropometric examinations, such as body mass index, fat free mass and fat mass are used to diagnose it. Nutritional therapy affects the course and prognosis of these diseases. Diet should be individually adjusted to the calculated caloric intake that increases during exacerbation of disease, because of increased respiratory effort. Too large supply of energy can cause increase metabolism, higher oxygen consumption and PaCO2 increase each dangerous for patients with respiratory insufficiency. Main source of carbohydrates for these patients should be products with low glycemic index and with high dietary fiber contents. Large meals should be avoided since they cause rapid satiety, abdominal discomfort and have negative impact on the work of the respiratory muscles, especially of the diaphragm. Dietary supplements can be used in case of ineffectiveness of diet or for the patients with severe undernutrition.

  13. The importance of need for cognition and educational experience in enhanced and standard substance abuse treatment.

    Czuchry, Michael; Dansereau, Donald F

    2004-06-01

    The current study examined the relationship between need for cognition (i.e., cognitive motivation or "will") and educational experience (i.e., cognitive ability or "skill") to perceived improvements during treatment of probationers receiving residential treatment within the criminal justice system. Probationers were randomly assigned to either receive motivational activities developed by the authors (the "enhanced" condition), or treatment as usual (but with access to general reading materials in lieu of the motivational activities). Need for cognition and educational experience were assessed and used as blocking variables, and ratings of progress were assessed midway and toward the end of treatment. The results indicate that both need for cognition and educational experience are important predictors of improvement during treatment, and that the motivational activities developed by the authors were particularly valuable for clients with lower levels of need for cognition.

    2006-04-01

    To assess the potential clinical use, particularly in modulating stress, of changes in the cardiovascular and respiratory systems induced by music, specifically tempo, rhythm, melodic structure, pause, individual preference, habituation, order effect of presentation, and previous musical training. Measurement of cardiovascular and respiratory variables while patients listened to music. University research laboratory for the study of cardiorespiratory autonomic function. 12 practising musicians and 12 age matched controls. After a five minute baseline, presentation in random order of six different music styles (first for a two minute, then for a four minute track), with a randomly inserted two minute pause, in either sequence. Breathing rate, ventilation, carbon dioxide, RR interval, blood pressure, mid-cerebral artery flow velocity, and baroreflex. Ventilation, blood pressure, and heart rate increased and mid-cerebral artery flow velocity and baroreflex decreased with faster tempi and simpler rhythmic structures compared with baseline. No habituation effect was seen. The pause reduced heart rate, blood pressure, and minute ventilation, even below baseline. An order effect independent of style was evident for mid-cerebral artery flow velocity, indicating a progressive reduction with exposure to music, independent of style. Musicians had greater respiratory sensitivity to the music tempo than did non-musicians. Music induces an arousal effect, predominantly related to the tempo. Slow or meditative music can induce a relaxing effect; relaxation is particularly evident during a pause. Music, especially in trained subjects, may first concentrate attention during faster rhythms, then induce relaxation during pauses or slower rhythms.

  16. Sci-Fri PM: Radiation Therapy, Planning, Imaging, and Special Techniques - 05: A novel respiratory motion simulation program for VMAT treatment plans: a phantom validation study

    Hubley, Emily; Pierce, Greg; Ploquin, Nicolas

    2016-01-01

    Purpose: To develop and validate a computational method to simulate craniocaudal respiratory motion in a VMAT treatment plan. Methods: Three 4DCTs of the QUASAR respiratory motion phantom were acquired with a 2cm water-density spherical tumour embedded in cedar to simulate lung. The phantom was oscillating sinusoidally with an amplitude of 2cm and periods of 3, 4, and 5 seconds. An ITV was contoured and 5mm PTV margin was added. High and a low modulation factor VMAT plans were created for each scan. An in-house program was developed to simulate respiratory motion in the treatment plans by shifting the MLC leaf positions relative to the phantom. Each plan was delivered to the phantom and the dose was measured using Gafchromic film. The measured and calculated plans were compared using an absolute dose gamma analysis (3%/3mm). Results: The average gamma pass rate for the low modulation plan and high modulation plans were 91.1% and 51.4% respectively. The difference between the high and low modulation plans gamma pass rates is likely related to the different sampling frequency of the respiratory curve and the higher MLC leaf speeds in the high modulation plan. A high modulation plan has a slower gantry speed and therefore samples the breathing cycle at a coarser frequency leading to inaccuracies between the measured and planned doses. Conclusion: A simple program, including a novel method for increasing sampling frequency beyond the control point frequency, has been developed to simulate respiratory motion in VMAT plans by shifting the MLC leaf positions.

  1. Evaluation of respiratory pattern during respiratory-gated radiotherapy

    Dobashi, Suguru; Mori, Shinichiro

    2014-01-01

    The respiratory cycle is not strictly regular, and generally varies in amplitude and period from one cycle to the next. We evaluated the characteristics of respiratory patterns acquired during respiratory gating treatment in more than 300 patients. A total 331 patients treated with respiratory-gated carbon-ion beam therapy were selected from a group of patients with thoracic and abdominal conditions. Respiratory data were acquired for a total of 3,171 fractions using an external respiratory sensing monitor and evaluated for respiratory cycle, duty cycle, magnitude of baseline drift, and intrafractional/interfractional peak inhalation/exhalation positional variation. Results for the treated anatomical sites and patient positioning were compared. Mean ± SD respiratory cycle averaged over all patients was 4.1 ± 1.3 s. Mean ± SD duty cycle averaged over all patients was 36.5 ± 7.3 %. Two types of baseline drift were seen, the first decremental and the second incremental. For respiratory peak variation, the mean intrafractional variation in peak-inhalation position relative to the amplitude in the first respiratory cycle (15.5 ± 9.3 %) was significantly larger than that in exhalation (7.5 ± 4.6 %). Interfractional variations in inhalation (17.2 ± 18.5 %) were also significantly greater than those in exhalation (9.4 ± 10.0 %). Statistically significant differences were observed between patients in the supine position and those in the prone position in mean respiratory cycle, duty cycle, and intra-/interfractional variations. We quantified the characteristics of the respiratory curve based on a large number of respiratory data obtained during treatment. These results might be useful in improving the accuracy of respiratory-gated treatment.

    The radiation treatments are based on geometric information and density of the CT images obtained for each patient. As a result of the motion blur produced in the imaging studies, the sizes, shapes and densities of the structures can be altered. The aim of this study was to determine the magnitude of these variations caused by respiratory motion in the CT study according to the conditions of image acquisition.

  4. Probiotics for the treatment of upper and lower respiratory-tract infections in children: systematic review based on randomized clinical trials

    Georgia Véras de Araujo

    2015-10-01

    Full Text Available ABSTRACT OBJECTIVES: Evaluate the effect of probiotics on the symptoms, duration of disease, and the occurrence of new episodes of upper and lower respiratory infections in healthy children. SOURCES: In order to identify eligible randomized controlled trials, two reviewers accessed four electronic databases [MEDLINE/PubMed, Scopus (Elsevier, Web of Science, and Cochrane (Cochrane VHL], as well as ClinicalTrials.gov until January 2015. Descriptors were determined by using the Medical Subject Headings tool, following the same search protocol. SUMMARY OF THE FINDINGS: Studies showed to be heterogeneous regarding strains of probiotics, the mode of administration, the time of use, and outcomes. The present review identified 11 peer-reviewed, randomized clinical trials, which analyzed a total of 2417 children up to 10 incomplete years of age. In the analysis of the studies, reduction in new episodes of disease was a favorable outcome for the use of probiotics in the treatment of respiratory infections in children. It is noteworthy that most of these studies were conducted in developed countries, with basic sanitation, health care, and strict, well-established and well-organized guidelines on the use of probiotics. Adverse effects were rarely reported, demonstrating probiotics to be safe. CONCLUSIONS: Despite the encouraging results - reducing new episodes of respiratory infections - the authors emphasize the need for further research, especially in developing countries, where rates of respiratory infections in children are higher when compared to the high per capita-income countries identified in this review.

  5. Evaluation of MotionSim XY/4D for patient specific QA of respiratory gated treatment for lung cancer

    2011-01-01

    Full text: A commercial system-MotionSim XY/4D(TM) capable of simulating two-dimensional tumour motion and measuring planar dose with diode-matrix was evaluated at the Alfred Hospital, for establishing patient-specific QA programme of respiratory gated treatment of lung cancer. This study presents the investigation of accuracies, limitations and the practical aspects of that system. Planar doses generated on iPlan-TM by mapping clinical beams to a scanned-in water phantom were measured by MotionSim XY/4D-TM with 5 cm water equivalent build-up at normal incidence. The gated delivery using ExacTrac-TM through tracking infrared markers simulating external respiration surrogate was measured simultaneously with Gaf-ChromicR RTQA2 film and MapCHECK 2TM . Dose maps of both non-gated and gated beams with 30% duty cycle were compared with both film and diodes measurements. Differences in dose distribution were analysed with built-in tools in MapCHECK2 TM and the effect of residual motion within the beamenabled window was then assessed. Preliminary results indicate that difference between Gafchromic film and MapCHECK2 measurements of same beam was ignorable. Gated dose delivery to a target at 9 mm maximum motion was in good agreement with planned dose. Complement to measurements suggested in AAPM Report No.9 I I, this QA device can detect any random error and assess the magnitude of residual target motion through analysing differences between planned and delivered doses as gamma function. Although some user-friendliness aspects could be improved, it meets its specification and can be used for routine clinical QA purposes provided calibrations were performed and procedures were followed.

Participants were asked to choose between hypothetical medication alternatives defined by attributes and levels that were varied systematically. The six treatment attributes included in the DCE were time to improvement, risk of becoming manic, weight gain, risk of sedation, increased blood sugar, and increased cholesterol. Attributes were supported by literature review, expert input, and results of focus groups with patients. Sawtooth CBC System for Choice-Based Conjoint Analysis was used to estimate the part-worth utilities for the DCE analyses.Results: The analytical sample included 185 participants (50.8% females from a total of 200 participants. The DCE analyses found weight gain to be the most important treatment attribute (relative importance =49.6%, followed by risk of sedation (20.2%, risk of mania (13.0%, increased blood sugar (8.3%, increased cholesterol (5.2%, and time to improvement (3.7%.Conclusion: Results from this DCE suggest that adults with bipolar depression considered risks of weight gain and sedation associated with pharmacotherapy as the most important attributes for the treatment of bipolar depression. Incorporating patient preferences in the treatment decision-making process may potentially have an impact on treatment adherence and satisfaction and, ultimately, patient outcomes.

  7. How Do Psychiatrists Apply the Minimum Clinically Important Difference to Assess Patient Responses to Treatment?

    Alan J. McMichael BSc

    2016-11-01

    Full Text Available Symptom report scales are used in clinical practice to monitor patient outcomes. Using them permits the definition of a minimum clinically important difference (MCID beyond which a patient may be judged as having responded to treatment. Despite recommendations that clinicians routinely use MCIDs in clinical practice, statisticians disagree about how MCIDs should be used to evaluate individual patient outcomes and responses to treatment. To address this issue, we asked how clinicians actually use MCIDs to evaluate patient outcomes in response to treatment. Sixty-eight psychiatrists made judgments about whether hypothetical patients had responded to treatment based on their pre- and posttreatment change scores on the widely used Positive and Negative Syndrome Scale. Psychiatrists were provided with the scale’s MCID on which to base their judgments. Our secondary objective was to assess whether knowledge of the patient’s genotype influenced psychiatrists’ responder judgments. Thus, psychiatrists were also informed of whether patients possessed a genotype indicating hyperresponsiveness to treatment. While many psychiatrists appropriately used the MCID, others accepted a far lower posttreatment change as indicative of a response to treatment. When psychiatrists accepted a lower posttreatment change than the MCID, they were less confident in such judgments compared to when a patient’s posttreatment change exceeded the scale’s MCID. Psychiatrists were also less likely to identify patients as responders to treatment if they possessed a hyperresponsiveness genotype. Clinicians should recognize that when judging patient responses to treatment, they often tolerate lower response thresholds than warranted. At least some conflate their judgments with information, such as the patient’s genotype, that is irrelevant to a post hoc response-to-treatment assessment. Consequently, clinicians may be at risk of persisting with treatments that have failed

  8. Development and evaluation of aerosol delivery of antivirals for the treatment of equine virus induced respiratory infections

    Martens, J.G.

    1985-01-01

    An aerosol delivery system incorporating the DeVilbiss ultrasonic nebulizer was developed for antiviral chemotherapy of equine viral respiratory infections. The system's delivery capabilities were proven effective by two modes of analysis: (a) a non-destructive, non-invasive radioactive tracer method utilizing a saline solution of DTPA labelled 99mTc and, (b) an invasive-terminal study using fluorescent polystyrene monodispersed latex particles. Particles were efficiently distributed throughout the lung parenchyma with deposition more heavily concentrated in the tracheobronchial region. Amantadine HCl was administered to the lungs of a yearling horse and three yearling Shetland ponies over a single 15-30 minute period with no untoward side effects. Likewise, ribavirin was aerosolized into the respiratory trace of an adult pony and a yearling horse for 15-30 minutes twice a day for three and seven days respectively. Neither the horse nor pony demonstrated signs of clinical illness or other signs of ribavirin toxicity. Attempts to produce a reproducible equine influenza disease model were made. During these studies, the authors were unsuccessful in developing a consistent respiratory disease model. Without this model the efficacy of antiviral compounds cannot be assessed. From the data generated in these studies, the implication of equine influenza viruses as the major single etiological agents responsible for equine respiratory disease is brought into question. Further, the author proposed that equine respiratory disease is a multiple agent-induced disease, which needs extensive investigation

    Kenya's neonatal mortality rate remains unacceptably high, at 22 deaths per 1000 live births, with a third of those attributable to prematurity. Respiratory distress syndrome (RDS) is the single most important cause of morbidity and mortality in the premature neonate. Continuous positive airway pressure (CPAP) is a proven modality of therapy but is rarely used in low-resource settings. We report on the introduction of bubble CPAP (BCPAP), a low-cost method of delivering CPAP appropriate to our setting, by comparing survival-to-discharge before and after the technology was introduced. The inpatient hospital records of all preterm infants (<37 weeks) diagnosed with RDS in the AIC Kijabe Hospital Nursery during two 18-month periods before and after the introduction of BCPAP (46 infants enrolled from 1 November 2007 to 30 April 2009 vs. 72 infants enrolled from 1 November 2009 to 30 April 2011) were reviewed. Differences in survival-to-discharge rates between the two time periods were analyzed. The survival-to-discharge rate was higher in Period 2 (after the introduction of BCPAP) than in Period 1 (pre-BCPAP) (85% vs. 61%, p  =  0.007). Similarly, there were lower referral rates of preterm infants with RDS in Period 2 than Period 1 (4% vs. 17%, p  =  0.037). BCPAP has contributed significantly to favorable outcomes for preterm infants with RDS at AIC Kijabe Hospital. The use of this simple technology should be considered and studied for expansion to all hospitals in Kenya that care for preterm infants. © The Author [2016]. Published by Oxford University Press.

    2014-04-01

    To develop a comprehensive conceptual framework representing the most important outcomes for women seeking treatment for pelvic organ prolapse (POP). Twenty-five women with POP were recruited and participated in four semi-structured focus groups to refine and assess the content validity of a conceptual framework representing patient-important outcomes for POP. Specifically, the focus groups addressed the following three aims: (1) to evaluate the content and appropriateness of domains in our framework; (2) to identify gaps in the framework; and (3) to determine the relative importance of our framework domains from the patient perspective. Sessions were transcribed, coded, and qualitatively and quantitatively analyzed using analytic induction and deductive analysis to identify themes and domains relevant to women with POP. Our focus groups confirmed the importance of vaginal bulge symptoms (discomfort, bother, and adaptation), and the overarching domains and subdomains of physical (physical function and participation), social (social function, relationships, and sexual function), and mental health (emotional distress, preoccupation, and body image). Patients ranked outcomes in the following order of importance: (1) the resolution of vaginal bulge symptoms, (2) improvement in physical function; (3) improvement in sexual function; (4) improvement in body image perception; and (5) improvement in social function. We developed a conceptual framework for patient important outcomes of women seeking treatment for POP. This framework can improve the transparency and interpretation of POP study findings from the patient perspective. Vaginal bulge and its associated discomfort are most important for the definition of POP treatment success from the patient perspective. © 2013 Wiley Periodicals, Inc.

    This book thoroughly covers each subfield of respiratory mechanics: pulmonary mechanics, the respiratory pump, and flow. It presents the current understanding of the field and serves as a guide to the scientific literature from the golden age of respiratory mechanics, 1960 - 2010. Specific topics covered include the contributions of surface tension and tissue forces to lung recoil, the gravitational deformation of the lung, and the interdependence forces that act on pulmonary airways and blood vessels. The geometry and kinematics of the ribs is also covered in detail, as well as the respiratory action of the external and internal intercostal muscles, the mechanics of the diaphragm, and the quantitative compartmental models of the chest wall is also described. Additionally, flow in the airways is covered thoroughly, including the wave-speed and viscous expiratory flow-limiting mechanisms; convection, diffusion and the stationary front; and the distribution of ventilation. This is an ideal book for respiratory ...

  12. The sodium level. An inconspicuous but very important parameter in all-volatile treatment

    Boiler tube failure due to ''lack of sodium''? This is certainly not a common concern, yet this contribution stresses the importance of the presence of sodium in the boiler water even when applying all-volatile treatment (AVT) as a method of boiler water treatment. Sodium in the cycle (either unintentionally via sodium-contaminated makeup or intentionally through sodium hydroxide additions) may neutralize the possible acidic contaminations and help to avoid boiler tube failures due to hydrogen damage.

  13. Etiology of acute lower respiratory tract infections in children: current state of the issue (review

    A. V. Bogdanova

    2016-01-01

    Full Text Available Acute lower respiratory tract infections are the leading cause of global morbidity and mortality in children under five years. Verification of the etiology of acute lower respiratory tract infections is necessary for definition of treatment and direction of prevention. Respiratory syncytial virus, influenza A and B, parainfluenza 1, 2, and 3 and adenovirus are considered the main reasons of acute lower respiratory tract infections. The importance of different viruses depends on countries, district, seasons and ages of children. Analysis of the results of studies from different regions of the world showed fluctuations in frequency of etiology definition of respiratory viruses from 25 to 90%. Respiratory syncytial virus is the main reason of acute lower respiratory tract infections, especially in the group of children up to 1 year.

  14. Respiratory guiding system for respiratory motion management in respiratory gated radiotherapy

    Kang, Seong Hee; Kim, Dong Su; Kim, Tae Ho; Suh, Tae Suk

    2013-01-01

    Respiratory guiding systems have been shown to improve the respiratory regularity. This, in turn, improves the efficiency of synchronized moving aperture radiation therapy, and it reduces the artifacts caused by irregular breathing in imaging techniques such as four-dimensional computed tomography (4D CT), which is used for treatment planning in RGRT. We have previously developed a respiratory guiding system that incorporates an individual-specific guiding waveform, which is easy to follow for each volunteer, to improve the respiratory regularity. The present study evaluates the application of this system to improve the respiratory regularity for respiratory-gated radiation therapy (RGRT). In this study, we evaluated the effectiveness of an in-house-developed respiratory guiding system incorporating an individual specific guiding waveform to improve the respiratory regularity for RGRT. Most volunteers showed significantly less residual motion at each phase during guided breathing owing to the improvement in respiratory regularity. Therefore, the respiratory guiding system can clearly reduce the residual, or respiratory, motion in each phase. From the result, the CTV and the PTV margins during RGRT can be reduced by using the respiratory guiding system, which reduces the residual motions, thus improving the accuracy of RGRT

    Respiratory syncytial virus (RSV) is the most important cause of viral lower respiratory tract illness (LRI) in infants and children worldwide and causes significant LRI in the elderly and in immunocompromised patients. The goal of RSV vaccination is to prevent serious RSV-associated LRI. There are several obstacles to the development of successful RSV vaccines, including the need to immunize very young infants, who may respond inadequately to vaccination; the existence of two antigenically d...

  16. Assessing the effects of pharmacological agents on respiratory dynamics using time-series modeling.

    Wong, Kin Foon Kevin; Gong, Jen J; Cotten, Joseph F; Solt, Ken; Brown, Emery N

    2013-04-01

    Developing quantitative descriptions of how stimulant and depressant drugs affect the respiratory system is an important focus in medical research. Respiratory variables-respiratory rate, tidal volume, and end tidal carbon dioxide-have prominent temporal dynamics that make it inappropriate to use standard hypothesis-testing methods that assume independent observations to assess the effects of these pharmacological agents. We present a polynomial signal plus autoregressive noise model for analysis of continuously recorded respiratory variables. We use a cyclic descent algorithm to maximize the conditional log likelihood of the parameters and the corrected Akaike's information criterion to choose simultaneously the orders of the polynomial and the autoregressive models. In an analysis of respiratory rates recorded from anesthetized rats before and after administration of the respiratory stimulant methylphenidate, we use the model to construct within-animal z-tests of the drug effect that take account of the time-varying nature of the mean respiratory rate and the serial dependence in rate measurements. We correct for the effect of model lack-of-fit on our inferences by also computing bootstrap confidence intervals for the average difference in respiratory rate pre- and postmethylphenidate treatment. Our time-series modeling quantifies within each animal the substantial increase in mean respiratory rate and respiratory dynamics following methylphenidate administration. This paradigm can be readily adapted to analyze the dynamics of other respiratory variables before and after pharmacologic treatments.

  17. Use of Diabetes Treatment Satisfaction Questionnaire in Diabetes Care: Importance of Patient-Reported Outcomes

    2018-05-01

    Full Text Available The efficacy of diabetes treatment should not be evaluated solely by HbA1c levels as they should also focus on patient-reported outcomes (PROs, such as patient satisfaction, wellbeing and quality of life. The Diabetes Treatment Satisfaction Questionnaire (DTSQ has been developed to assess patient satisfaction with diabetes treatment. DTSQ has been translated into more than 100 languages and is widely used in many countries, since it is relatively easy to answer and is used for both patients with and without medical therapy. Novel therapeutic options, such as insulin analogs, incretin-based therapy and sodium-glucose cotransporter 2 (SGLT2 inhibitors, have been shown to improve patient satisfaction using DTSQ for assessments. DTSQ is not only used for comparisons between different medications or treatment strategies, but also can be used to assess the quality of diabetes care in clinical settings. This is important as an improvement in treatment satisfaction may enhance patients’ self-efficacy and adherence to therapy, leading to the achievement of long-term stable glycemic control and reduced risk of diabetic complications. In this review, we summarize the current topics in DTSQ, introducing our own experience, and discuss the role of PROs in diabetes treatment.

  18. Saving energy resources during heat treatment - the most important problem of the branch

    Zadernovskiy, V V; Firger, I V

    1980-01-01

    Natural gas fired thermal furnaces expend significantly less fuel than electric furnaces with an equal quality of metal heating. An important reserve in power reserve economy is the use of the forging heat in an article for heat treatment (TOB), where besides the power resources, metal is also saved as a result of the reduction in the volume of heating means and production spaces. From the experience in the progressive enterprises of the branch, in a number of cases it is possible to combine heating for plastic deformation with heating for primary or secondary heat treatment. Other measures are examined which save power resources in heat treatment: the use of thermal furnaces for aerodynamic heating, the use of local heat treatment, the reduction in the duration of the heat treatment processes, savings in the power carriers during heat treatment in furnaces with a roll out hearth. Fibrous refractory materials are being used more and more as fettling materials in the construction of thermal furnaces.

    1987-01-01

    The potential exposure to ribavirin aerosol in the environment was assessed in nurses caring for infants and children with severe lower respiratory tract infections due to respiratory syncytial virus. Ribavirin aerosol was administered via a ventilator, oxygen tent, or oxygen hood. Participants worked directly with infants receiving ribavirin for 20.0 to 35.0 h over a 3-day period. No toxic or adverse effects of ribavirin aerosol were observed in any of the 19 nurses studied, and ribavirin was not detected in erythrocytes, plasma, or urine collected after the potential exposure period.

    Climate change will affect individuals with pre-existing respiratory disease, but the extent of the effect remains unclear. The present position statement was developed on behalf of the European Respiratory Society in order to identify areas of concern arising from climate change for individuals with respiratory disease, healthcare workers in the respiratory sector and policy makers. The statement was developed following a 2-day workshop held in Leuven (Belgium) in March 2008. Key areas of concern for the respiratory community arising from climate change are discussed and recommendations made to address gaps in knowledge. The most important recommendation was the development of more accurate predictive models for predicting the impact of climate change on respiratory health. Respiratory healthcare workers also have an advocatory role in persuading governments and the European Union to maintain awareness and appropriate actions with respect to climate change, and these areas are also discussed in the position statement.

    Full Text Available Introduction: Stuttering is not a problem of individuals, but it’s a problem in the verbal communication with others. Individual and group treatment is equally important to use while working with people who stutter.Purpose: Group treatment is used to allow the patient adequate adjustment in all problematic situations (situations increasing stuttering in the environment and to gradually inhibit negative emotions.Material and methods: Objective speech tool is used in this testing (evaluation of speech status under Fiedler, PA Standop, R.Stotern-Schwarzenberg, Munchen, 1978 to determine the degree and type of speech disorder. The anxiety feeling is also evaluated, where the subjective assessment of patients' anxiety is expressed in units SUD (subjective units of disturbance or distress - subjective assessment of suffering.Results and Conclusion: The results showed that group stationary treatment has a huge significance in reducing the anxiety of patients who stutter.

  3. The Role of Omega-3 Polyunsaturated Fatty Acids in the Treatment of Patients with Acute Respiratory Distress Syndrome: A Clinical Review

    M. García de Acilu

    2015-01-01

    Full Text Available Acute respiratory distress syndrome (ARDS is defined as the acute onset of noncardiogenic edema and subsequent gas-exchange impairment due to a severe inflammatory process. Recent report on the prognostic value of eicosanoids in patients with ARDS suggests that modulating the inflammatory response through the use of polyunsaturated fatty acids may be a useful strategy for ARDS treatment. The use of enteral diets enriched with eicosapentaenoic acid (EPA and gamma-linolenic acid (GLA has reported promising results, showing an improvement in respiratory variables and haemodynamics. However, the interpretation of the studies is limited by their heterogeneity and methodology and the effect of ω-3 fatty acid-enriched lipid emulsion or enteral diets on patients with ARDS remains unclear. Therefore, the routine use of ω-3 fatty acid-enriched nutrition cannot be recommended and further large, homogeneous, and high-quality clinical trials need to be conducted to clarify the effectiveness of ω-3 polyunsaturated fatty acids.

    Amir-Mohammad Armanian

    2014-01-01

    Full Text Available Background: Neonatal respiratory distress syndrome (RDS in premature infants who survived and its complications are a common problem. Due to high morbidity and mechanical ventilation (MV nowadays researchers in interested minimizing MV. To determine, in very low birth weight (BW preterm neonates with RDS, if initial treatment with nasal intermittent mandatory ventilation (early NIMV compared with early nasal continuous positive airway pressure (early NCPAP obtains more favorable outcomes in terms of the duration of treatment, and the need for endotracheal tube ventilation. Methods: In this single-center randomized control trial study, infants (BW ≤ 1500 g and/or gestational age ≤ 34 weeks with respiratory distress were considered eligible. Forty-four infants were randomly assigned to receive early-NIMV and 54 comparable infants to early-NCPAP. Surfactants were given, when FIO 2 requirement was of >30%. Primary outcomes were failure of noninvasive respiratory support, that is, the need for MV in the first 48 h of life and for the duration of noninvasive respiratory support in each group. Results: 98 infants were enrolled (44 in the NIMV and 54 in the NCPAP group. The Preventive power of MV of NIMV usage (95.5% was not lower than the NCPAP (98.1% strength (hazard ratio: 0.21 (95% confidence interval: 0.02-2.66; P: 0.23. The duration of noninvasive respiratory support in the NIMV group was significantly shorter than NCPAP (the median (range was 24 (18.00-48.00 h versus 48.00 (22.00-120.00 h in NIMV versus NCPAP groups; P < 0.001. Similarly, the duration of dependency on oxygen was less, for NIMV (the median (range was 96.00 (41.00-504.00 h versus144.00 (70.00-1130.00 h in NIMV versus NCPAP groups; P: 0.009. Interestingly, time to full enteral feeds and length of hospital stay were more favorable in the NIMV versus the NCPAP group. Conclusions: Initial treatment of RDS with NIMV was safe, and well tolerated. Furthermore, NIMV had excellent

  5. Influence of patient symptoms and physical findings on general practitioners' treatment of respiratory tract infections: a direct observation study

    Kochen Michael M

    2005-02-01

    Full Text Available Abstract Background The high rate of antibiotic prescriptions general practitioners (GPs make for respiratory tract infections (RTI are often explained by non-medical reasons e.g. an effort to meet patient expectations. Additionally, it is known that GPs to some extent believe in the necessity of antibiotic treatment in patients with assumed bacterial infections and therefore attempt to distinguish between viral and bacterial infections by history taking and physical examination. The influence of patient complaints and physical examination findings on GPs' prescribing behaviour was mostly investigated by indirect methods such as questionnaires. Methods Direct, structured observation during a winter "cough an cold period" in 30 (single handed general practices. All 273 patients with symptoms of RTI (age above 14, median 37 years, 51% female were included. Results The most frequent diagnoses were 'uncomplicated upper RTI/common cold' (43% followed by 'bronchitis' (26%. On average, 1.8 (95%-confidence interval (CI: 1.7–2.0 medicines per patient were prescribed (cough-and-cold preparations in 88% of the patients, antibiotics in 49%. Medical predictors of antibiotic prescribing were pathological findings in physical examination such as coated tonsils (odds ratio (OR 15.4, 95%-CI: 3.6–66.2 and unspecific symptoms like fatigue (OR 3.1, 95%-CI 1.4–6.7, fever (OR 2.2, 95%-CI: 1.1–4.5 and yellow sputum (OR 2.1, 95%-CI: 1.1–4.1. Analysed predictors explained 70% of the variance of antibiotic prescribing (R2 = 0,696. Efforts to reduce antibiotic prescribing, e.g. recommendations for self-medication, counselling on home remedies or delayed antibiotic prescribing were rare. Conclusions Patient complaints and pathological results in physical examination were strong predictors of antibiotic prescribing. Efforts to reduce antibiotic prescribing should account for GPs' beliefs in those (non evidence based predictors. The method of direct observation was

    This study investigated the perspective of international patients on individual symptoms of atopic dermatitis (eczema) in determining treatment response. A questionnaire was developed to evaluate the importance of symptoms from the patient's perspective. Patients were asked: "How important are these features in deciding whether or not a treatment is working?", and rated symptoms on a 5-point Likert scale. Patients were approached via Harmonising Outcome Measures for Eczema (HOME) collaborators and self-selected to take part in the on-line survey. Patients from 34 countries (n = 1,111) completed the survey; of these, 423 (38.3%) were parents of children with eczema. Nine items were rated as being "quite important" or "very important" by more than 80% of the respondents: itch, pain/soreness, skin feels hot or inflamed, bleeding, involvement of visible or sensitive body sites, cracks, sleep difficulties, amount of body affected, and weeping/oozing. These results may be of use in determining the face validity of scales from a cross-cultural patients' perspective.

  8. Root resorption: Focus on signs and symptoms of importance for avoiding root resorption during orthodontic treatment

    Inger Kjaer

    2014-01-01

    Full Text Available Introduction: This paper summarizes the different conditions, which have a well-known influence on the resorption of tooth roots, exemplified by trauma and orthodontic treatment. The concept of the paper is to summarize and explain symptoms and signs of importance for avoiding resorption during orthodontic treatment. The Hypothesis: The hypothesis in this paper is that three different tissue layers covering the root in the so-called periroot sheet can explain signs and symptoms of importance for avoiding root resorption during orthodontic treatment. These different tissue layers are; outermost - an ectodermal tissue layer (Malassez′s epithelium, a middle layer - composed by the collagen-mesodermal tissue layer, and an innermost root-close innervation layer. Abnormalities in one of these tissue layers are thought to cause inflammatory processes in the periodontal membrane comparable to inflammatory processes provoked by trauma and orthodontic pressure. Inflammatory reactions are followed by resorptive processes in the periroot sheet and along the root surface. Evaluation of the Hypothesis: Different morphologies in the dentition are signs of abnormal epithelium or an abnormal mesodermal layer. It has formerly been demonstrated how demyelinization of the myelin sheaths in the peripheral nerves close to the root provoke resorption. Accordingly, conditions affecting these tissue layers can be associated not only with different morphologies but also with general symptoms and diseases (e.g., ectodermal dysplasia and hypophosphatasia.

  9. The Importance of Rare Subtypes in Diagnosis and Treatment of Peripheral Neuropathy: A Review.

    Callaghan, Brian C; Price, Raymond S; Chen, Kevin S; Feldman, Eva L

    2015-12-01

    Peripheral neuropathy is a prevalent condition that usually warrants a thorough history and examination but has limited diagnostic evaluation. However, rare localizations of peripheral neuropathy often require more extensive diagnostic testing and different treatments. To describe rare localizations of peripheral neuropathy, including the appropriate diagnostic evaluation and available treatments. References were identified from PubMed searches conducted on May 29, 2015, with an emphasis on systematic reviews and randomized clinical trials. Articles were also identified through the use of the authors' own files. Search terms included common rare neuropathy localizations and their causes, as well as epidemiology, pathophysiology, diagnosis, and treatment. Diffuse, nonlength-dependent neuropathies, multiple mononeuropathies, polyradiculopathies, plexopathies, and radiculoplexus neuropathies are rare peripheral neuropathy localizations that often require extensive diagnostic testing. Atypical neuropathy features, such as acute/subacute onset, asymmetry, and/or motor predominant signs, are frequently present. The most common diffuse, nonlength-dependent neuropathies are Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, and amyotrophic lateral sclerosis. Effective disease-modifying therapies exist for many diffuse, nonlength-dependent neuropathies including Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, and some paraprotein-associated demyelinating neuropathies. Vasculitic neuropathy (multiple mononeuropathy) also has efficacious treatment options, but definitive evidence of a treatment effect for IgM anti-MAG neuropathy and diabetic amyotrophy (radiculoplexus neuropathy) is lacking. Recognition of rare localizations of peripheral neuropathy is essential given the implications for diagnostic testing and treatment. Electrodiagnostic studies are an important

    Acute respiratory tract infections account for the majority of antibiotic exposure in children, and broad-spectrum antibiotic prescribing for acute respiratory tract infections is increasing. It is not clear whether broad-spectrum treatment is associated with improved outcomes compared with narrow-spectrum treatment. To compare the effectiveness of broad-spectrum and narrow-spectrum antibiotic treatment for acute respiratory tract infections in children. A retrospective cohort study assessing clinical outcomes and a prospective cohort study assessing patient-centered outcomes of children between the ages of 6 months and 12 years diagnosed with an acute respiratory tract infection and prescribed an oral antibiotic between January 2015 and April 2016 in a network of 31 pediatric primary care practices in Pennsylvania and New Jersey. Stratified and propensity score-matched analyses to account for confounding by clinician and by patient-level characteristics, respectively, were implemented for both cohorts. Broad-spectrum antibiotics vs narrow-spectrum antibiotics. In the retrospective cohort, the primary outcomes were treatment failure and adverse events 14 days after diagnosis. In the prospective cohort, the primary outcomes were quality of life, other patient-centered outcomes, and patient-reported adverse events. Of 30 159 children in the retrospective cohort (19 179 with acute otitis media; 6746, group A streptococcal pharyngitis; and 4234, acute sinusitis), 4307 (14%) were prescribed broad-spectrum antibiotics including amoxicillin-clavulanate, cephalosporins, and macrolides. Broad-spectrum treatment was not associated with a lower rate of treatment failure (3.4% for broad-spectrum antibiotics vs 3.1% for narrow-spectrum antibiotics; risk difference for full matched analysis, 0.3% [95% CI, -0.4% to 0.9%]). Of 2472 children enrolled in the prospective cohort (1100 with acute otitis media; 705, group A streptococcal pharyngitis; and 667, acute sinusitis), 868

    Methotrexate (MTX) is the most commonly used disease-modifying antirheumatic drug in juvenile idiopathic arthritis (JIA). Currently, individual response to MTX cannot be reliably predicted. Identification of clinical and genetic factors that influence the response to MTX could be helpful in realizing the optimal treatment for individual patients. A cohort of 128 JIA patients treated with MTX were studied retrospectively. Eleven clinical parameters and genotypes of 6 single nucleotide polymorphisms in 5 genes related to the mechanism of action of MTX were compared between MTX responders and nonresponders using a multivariate regression analysis. The time from diagnosis to start of MTX treatment, physician's global assessment at baseline, and the starting dose were significantly associated with the response to MTX at 6 months after initiation. Patients with a shorter time from diagnosis to start of MTX and a higher disease activity according to the physician but with a lower MTX dose showed an increased response. The effect of the starting dose on MTX response seemed to be mainly due to the influence of the systemic JIA subtype. The time from diagnosis to start of MTX treatment and physician's global assessment at baseline were highly correlated. Therefore, the precise effect size of each independent variable could not be determined. In children with JIA, the time from diagnosis to start of MTX appears to be an important factor for MTX response. Our results suggest that an earlier start of MTX treatment will lead to an increased response.

  12. The importance of early diagnosis and treatment of kaposiform hemangioendothelioma complicated by Kasabach-Merritt phenomenon.

    2015-01-01

    Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor that may be complicated by Kasabach-Merritt phenomenon (KMP), a profound thrombocytopenia resulting from platelet trapping within a vascular tumor, either KHE or tufted angioma (TA). Typical features also include low fibrinogen and elevated D-dimers. It is well known that KMP is not caused by infantile hemangiomas. Management of vascular tumors complicated by KMP is challenging, and it is common for referral centers to receive patients in critical medical condition after multimodality treatment failure of vascular anomalies. Our aim is to communicate the importance of early diagnosis and treatment of KHE associated with KMP. A full-term male newborn with KHE complicated by KMP is reported. Treatment with vincristine, aspirin and ticlopidine normalized the coagulation parameters within one week, requiring a total of six doses of vincristine, seven months of ticlopidine and 17 months of aspirin. Early diagnosis and treatment of KHE complicated by KMP may allow the administration of fewer doses of vincristine and avoid the use of corticosteroids.

    Statins are used to lower cholesterol in plasma and are one of the most used drugs in the world. Many statin users experience muscle pain, but the mechanisms are unknown at the moment. Many studies have hypothesized that mitochondrial function could be involved in these side effects. The aim of the study was to investigate mitochondrial function after 2 weeks of treatment with simvastatin (S; n = 10) or pravastatin (P; n = 10) in healthy middle-aged participants. Mitochondrial respiratory capacity and substrate sensitivity were measured in permeabilized muscle fibers by high-resolution respirometry. Mitochondrial content (citrate synthase (CS) activity), antioxidant content, as well as coenzyme Q 10 concentration (Q 10 ) were determined. Fasting plasma glucose and insulin concentrations were measured, and whole body maximal oxygen uptake (VO 2max ) was determined. No differences were seen in mitochondrial respiratory capacity although a tendency was observed for a reduction when complex IV respiration was analyzed in both S (229 (169; 289 (95% confidence interval)) vs. 179 (146; 211) pmol/s/mg, respectively; P = 0.062) and P (214 (143; 285) vs. 162 (104; 220) pmol/s/mg, respectively; P = 0.053) after treatment. A tendency (1.64 (1.28; 2.00) vs. 1.28 (0.99; 1.58) mM, respectively; P = 0.092) for an increased mitochondrial substrate sensitivity (complex I-linked substrate; glutamate) was seen only in S after treatment. No differences were seen in Q 10 , CS activity, or antioxidant content after treatment. Fasting glucose and insulin as well as VO 2max were not changed after treatment. Two weeks of statin (S or P) treatment have no major effect on mitochondrial function. The tendency for an increased mitochondrial substrate sensitivity after simvastatin treatment could be an early indication of the negative effects linked to statin treatment.

    Middle Eastern Respiratory Syndrome coronavirus (MERS-CoV) is a poorly understood disease with no known treatments. We describe the clinical features and treatment outcomes of patients with laboratory confirmed MERS-CoV at a regional referral center in the Kingdom of Saudi Arabia. In 2014, a retrospective chart review was performed on patients with a laboratory confirmed diagnosis of MERS-CoV to determine clinical and treatment characteristics associated with death. Confounding was evaluated and a multivariate logistic regression was performed to assess the independent effect of treatments administered. Fifty-one patients had an overall mortality of 37 %. Most patients were male (78 %) with a mean age of 54 years. Almost a quarter of the patients were healthcare workers (23.5 %) and 41 % had a known exposure to another person with MERS-CoV. Survival was associated with male gender, working as a healthcare worker, history of hypertension, vomiting on admission, elevated respiratory rate, abnormal lung exam, elevated alanine transaminase (ALT), clearance of MERS-CoV on repeat PCR polymerase chain reaction (PCR) testing, and mycophenolate mofetil treatment. Survival was reduced in the presence of coronary artery disease, hypotension, hypoxemia, CXR (chest X-ray) abnormalities, leukocytosis, creatinine >1 · 5 mg/dL, thrombocytopenia, anemia, and renal failure. In a multivariate analysis of treatments administered, severity of illness was the greatest predictor of reduced survival. Care for patients with MERS-CoV remains a challenge. In this retrospective cohort, interferon beta and mycophenolate mofetil treatment were predictors of increased survival in the univariate analysis. Severity of illness was the greatest predictor of reduced survival in the multivariate analysis. Larger randomized trials are needed to better evaluate the efficacy of these treatment regimens for MERS-CoV.

  15. The Importance of The Dentist – Patient Relationship in Oral Cancer Treatment

    Indrayadi Gunardi

    2017-09-01

    Full Text Available Background: There are many instances in oral cancer cases in which a lack of patient cooperation was found to be a hampering factor in the overall case management. A good relationship between dentists and patients should therefore be built in conjunction with other treatment modalities. Case Report: Three complete oral cancer cases with dentist–patient relationship problems are presented. One of the common basic ways to build a good relationship is through communication and empathy. A relationship is also influenced by psychological distress, experience from previous treatments, socioeconomic factors, the healthcare system, time constraints, and belief. Conclusion: No single intervention strategy can improve the compliance of an oral cancer patient. An assessment of patient knowledge and understanding of the regimen along with clear and effective communication and trust in the therapeutic relationship are important in the overall patient management.

    Full Text Available Aim: of our clinical study was to present own experience of veno-venous extracorporeal membrane oxygenation (VV ECMO for the treatment of an adult patient (female, 28 yrs, 150 cm, 35 kg with acute respiratory distress syndrome (ARDS in the early period after liver transplantation against satisfactory liver graft function. Materials and methods. Double-lumen cannula 22 F was placed percutaneously in the right internal jugular vein. The ext- racorporeal contour reduced in length and the polymethylpeptene oxygenator (priming volume 175 ml were also. Results. In 1 hour after the beginning of VV ECMO, we registered the noted improvement of arterial blood gas and acid-base balance (regress of respiratory acidosis, improvement of arterial oxygenation which allowed us to use the «protective» mode of mechanical ventilation. Improvement of gas exchange and regress of clinical and radiological manifestations of ARDS allowed for VV ECMO weaning and decannulation on day 7. The patient was discharged from ICU and then from our Centre to a homestay respectively on the 9th and 16th day after VV ECMO weaning with the satisfactory liver graft and lungs function. Conclusion. VV ECMO can be successfully applied to correct the life-threatening acute respiratory failure in the early period after liver transplantation.

    Inferring disease transmission networks is important in epidemiology in order to understand and prevent the spread of infectious diseases. Reconstruction of the infection transmission networks requires insight into viral genome data as well as social interactions. For the HIV-1 epidemic, current research either uses genetic information of patients' virus to infer the past infection events or uses statistics of sexual interactions to model the network structure of viral spreading. Methods for a reliable reconstruction of HIV-1 transmission dynamics, taking into account both molecular and societal data are still lacking. The aim of this study is to combine information from both genetic and epidemiological scales to characterize and analyse a transmission network of the HIV-1 epidemic in central Italy.We introduce a novel filter-reduction method to build a network of HIV infected patients based on their social and treatment information. The network is then combined with a genetic network, to infer a hypothetical infection transmission network. We apply this method to a cohort study of HIV-1 infected patients in central Italy and find that patients who are highly connected in the network have longer untreated infection periods. We also find that the network structures for homosexual males and heterosexual populations are heterogeneous, consisting of a majority of 'peripheral nodes' that have only a few sexual interactions and a minority of 'hub nodes' that have many sexual interactions. Inferring HIV-1 transmission networks using this novel combined approach reveals remarkable correlations between high out-degree individuals and longer untreated infection periods. These findings signify the importance of early treatment and support the potential benefit of wide population screening, management of early diagnoses and anticipated antiretroviral treatment to prevent viral transmission and spread. The approach presented here for reconstructing HIV-1 transmission networks

  19. SU-F-T-18: The Importance of Immobilization Devices in Brachytherapy Treatments of Vaginal Cuff

    Shojaei, M; Dumitru, N; Pella, S [21st Century Oncology, Boca Raton, FL (United States)

    2016-06-15

    Purpose: High dose rate brachytherapy is a highly localized radiation therapy that has a very high dose gradient. Thus one of the most important parts of the treatment is the immobilization. The smallest movement of the patient or applicator can result in dose variation to the surrounding tissues as well as to the tumor to be treated. We will revise the ML Cylinder treatments and their localization challenges. Methods: A retrospective study of 25 patients with 5 treatments each looking into the applicator’s placement in regard to the organs at risk. Motion possibilities for each applicator intra and inter fractionation with their dosimetric implications were covered and measured in regard with their dose variance. The localization immobilization devices used were assessed for the capability to prevent motion before and during the treatment delivery. Results: We focused on the 100% isodose on central axis and a 15 degree displacement due to possible rotation analyzing the dose variations to the bladder and rectum walls. The average dose variation for bladder was 15% of the accepted tolerance, with a minimum variance of 11.1% and a maximum one of 23.14% on the central axis. For the off axis measurements we found an average variation of 16.84% of the accepted tolerance, with a minimum variance of 11.47% and a maximum one of 27.69%. For the rectum we focused on the rectum wall closest to the 120% isodose line. The average dose variation was 19.4%, minimum 11.3% and a maximum of 34.02% from the accepted tolerance values Conclusion: Improved immobilization devices are recommended. For inter-fractionation, localization devices are recommended in place with consistent planning in regards with the initial fraction. Many of the present immobilization devices produced for external radiotherapy can be used to improve the localization of HDR applicators during transportation of the patient and during treatment.

    Objective: To analyze the phytochemicals that are present in two medicinal plants which are used for the treatment of respiratory tract infections by gas chromatography-mass spectrometer. Methods: The plant leaves were extracted withn-hexane and methanol separately. Both extracts were analyzed for present phytochemicals using the method described by Harborne, 1985 while only methanol extracts were subjected to gas chromatography-mass spectrometer analysis. Results:Phytochemical screening of the methanolic extracts ofTerminalia macroptera (T. macroptera) revealed the presence of glycosides, tannins, flavonoids, saponins and steroids while that ofDioclea reflexa (D. reflexa) showed the presence of flavonoids, saponins and steroids. Then-hexane extracts were devoid of the screened phytochemicals. Twelve and twenty-five compounds were identified in the leaves ofT. macroptera andD. reflexa respectively. These compounds were fatty acids, fatty acid esters, other esters, heterocyclics and phenolics. The most abundant compound inT. macroptera was benzenetriol (53.30%) while the predominant compounds inD. reflexa were dodecanoic acid, methyl ester (15.31%), 5, 5, 8a-trimethyl-3, 5, 6, 7, 8, 8a-hexahydro-2H-chromene (9.73%), 10-octadecenoic acid, methyl ester and 2-hexadecanoic acid, methyl ester (8.95%). Benzofuran, 2, 3-dihydro, 3, 7, 11, 15-tetramethyl-2-hexadecen-1-ol and hexadecanoic acid, methyl ester were common in both plant extracts. The antimicrobial properties of the leaves of these plants could be responsible for their use in the treatment of respiratory tract infections. Conclusions:Some of the identified phytochemicals in the plant leaves are responsible for its use in the treatment of respiratory tract infections.

  1. Management of Postoperative Respiratory Failure.

    Mulligan, Michael S; Berfield, Kathleen S; Abbaszadeh, Ryan V

    2015-11-01

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. Copyright © 2015 Elsevier Inc.

  2. Respiratory Syncytial Virus Bronchiolitis in Children.

    Smith, Dustin K; Seales, Sajeewane; Budzik, Carol

    2017-01-15

    Bronchiolitis is a common lower respiratory tract infection in infants and young children, and respiratory syncytial virus (RSV) is the most common cause of this infection. RSV is transmitted through contact with respiratory droplets either directly from an infected person or self-inoculation by contaminated secretions on surfaces. Patients with RSV bronchiolitis usually present with two to four days of upper respiratory tract symptoms such as fever, rhinorrhea, and congestion, followed by lower respiratory tract symptoms such as increasing cough, wheezing, and increased respiratory effort. In 2014, the American Academy of Pediatrics updated its clinical practice guideline for diagnosis and management of RSV bronchiolitis to minimize unnecessary diagnostic testing and interventions. Bronchiolitis remains a clinical diagnosis, and diagnostic testing is not routinely recommended. Treatment of RSV infection is mainly supportive, and modalities such as bronchodilators, epinephrine, corticosteroids, hypertonic saline, and antibiotics are generally not useful. Evidence supports using supplemental oxygen to maintain adequate oxygen saturation; however, continuous pulse oximetry is no longer required. The other mainstay of therapy is intravenous or nasogastric administration of fluids for infants who cannot maintain their hydration status with oral fluid intake. Educating parents on reducing the risk of infection is one of the most important things a physician can do to help prevent RSV infection, especially early in life. Children at risk of severe lower respiratory tract infection should receive immunoprophylaxis with palivizumab, a humanized monoclonal antibody, in up to five monthly doses. Prophylaxis guidelines are restricted to infants born before 29 weeks' gestation, infants with chronic lung disease of prematurity, and infants and children with hemodynamically significant heart disease.

  3. The importance of γ-linolenic acid in the prevention and treatment

    Małgorzata Białek

    2015-07-01

    Full Text Available The etiology of diet-related disorders is closely associated with dietary factors. A special role is attributed to intake of fat and fatty acid profile, both quantitative and qualitative. For prevention and treatment of the abovementioned diseases a proper supply of unsaturated fatty acids plays a significant role, because of their particular importance to health. γ-Linolenic acid (GLA, with three double bonds in the carbon chain, also known as all-cis 6,9,12-octadecatrienoic acid, belongs to the n-6 family of fatty acids. It plays biologically important functions in the human body, such as being a substrate for eicosanoids synthesis, involvement in the transport and oxidation of cholesterol, and being one of the components of lipid membrane. Its inadequate dietary intake or impaired formation is the cause of many inflammatory and degenerative diseases. A rich source of this fatty acid is vegetable oils, until recently used mainly in folk medicine. Nowadays, studies conducted both in animal models and in humans suggest its health-promoting properties in the prevention and treatment of atopic dermatitis, cardiovascular diseases, diabetes, cancers and rheumatoid arthritis.

  4. Hypothalamic obesity after treatment for craniopharyngioma: the importance of the home environment.

    Hypothalamic obesity after treatment for craniopharyngioma is a well-recognized, severe problem. Treatment of hypothalamic obesity is difficult and often frustrating for the patient, the parents and the professional care-giver. Because hypothalamic obesity is caused by an underlying medical disorder, it is often assumed that regular diet and exercise are not beneficial to reduce the extraordinarily high body mass index, and in fact, lifestyle interventions have been shown to be insufficient in case of extreme hypothalamic obesity. Nevertheless, it is important to realize that also in this situation, informal care delivered by the family and appropriate parenting styles are required to minimize the obesity problem. We present a case in which weight gain in the home situation was considered unstoppable, and a very early mortality due to complications of the severe increasing obesity was considered inevitable. A permissive approach toward food intake became leading with rapid weight increase since a restrictive lifestyle was considered a senseless burden for the child. By admission to our hospital for a longer period of time, weight reduction was realized, and the merely permissive approach could be changed into active purposeful care by adequate information, instruction, guidance and encouragement of the affected child and her parents. This case illustrates that, although this type of obesity has a pathological origin, parental and environmental influences remain of extreme importance.

  5. [Calcium and vitamin D in bone metabolism: Clinical importance for fracture treatment].

    Amling, M

    2015-12-01

    A balanced calcium homeostasis is of critical importance not only for bone remodeling, the physiological process of bone resorption and bone formation that constantly renews bone throughout life but also for normal fracture healing. Given that disturbances of calcium homeostasis are present in 50 % of the German population and that this might result in delayed fracture healing after correct surgical treatment, this paper focusses on calcium and vitamin D in the daily practice in orthopedics and trauma surgery. To ensure the required enteral calcium uptake the following three conditions are required: (1) sufficient calcium intake via the nutrition, (2) a 25-hydroxyvitamin D serum level > 30 µg/l and (3) the presence of sufficient gastric acidification. Given the endemic vitamin D deficiency in Germany as well as the constantly increasing number of people using proton pump inhibitors on a regular basis, it is necessary to closely connect trauma orthopedic surgery and osteological treatment. The first issue to be dealt with is to control and if needed normalize calcium homeostasis in order to allow a normal undisturbed fracture healing process after both conservative as well as operative treatment of fractures.

    This case report highlights the importance of pharmacogenetic testing in the treatment of attention deficit hyperactive disorder (ADHD). A 6-year-old boy diagnosed with ADHD was prescribed methylphenidate 5 mg twice daily (7 am and noon) and the family was compliant with administration of this medication. On the first day of treatment, the patient had an adverse reaction, becoming disobedient, more mischievous, erratic, resistant to discipline, would not go to sleep until midnight, and had a poor appetite. The All-In-One PGX (All-In-One Pharmacogenetics for Antipsychotics test for CYP2D6, CYP2C19, and CYP2C9) was performed using microarray-based and real-time polymerase chain reaction techniques. The genotype of our patient was identified to be CYP2D6*2/*10, with isoforms of the enzyme consistent with a predicted cytochrome P450 2D6 intermediate metabolizer phenotype. Consequently, the physician adjusted the methylphenidate dose to 2.5 mg once daily in the morning. At this dosage, the patient had a good response without any further adverse reactions. Pharmacogenetic testing should be included in the management plan for ADHD. In this case, cooperation between the medical team and the patients' relatives was key to successful treatment.

    2008-01-01

    Quality of life (QOL), and pulmonary and nutritional parameters are important outcome measures during treatment of lung cancer; however, the effect of chemotherapy on these factors and their relationship with clinical response is unclear. Patients with non-small cell lung cancer (NSCLC) were evaluated for symptom profile, nutritional status (using anthropometry), pulmonary functions by spirometry and six minute walk distance (6 MWD), and QOL using the WHO-QOL Bref 26 questionnaire, before and after chemotherapy. Forty-four patients were studied (mean (SD) age, 55 (10) years, 75% males). The majority (98%) had stage III or IV disease and 72% were current / ex-smokers with median pack-years of 27.0 (range, 0.5-90). Some 61% had a Karnofsky Performance Scale (KPS) 70 or 80. The commonest symptoms were coughing, dyspnea, chest pain, anorexia and fever (79%, 72%, 68%, 57% and 40%, respectively). The mean (SD) 6 MWD was 322.5 (132.6) meters. The mean (SD) percentage forced vital capacity (FVC %), and forced expiratory volume in one second (FEV1 %) were 64.7 (18.8) and 57.8 (19.4), respectively. The mean (SD) QOL scores for the physical, psychological, social, and environmental domains were 52.9 (20.5), 56.1 (17.9), 64.5 (21.8), 57.1 (16.6), respectively. Fourteen patients (32%) responded to chemotherapy. Non-responders had significantly higher baseline occurrence of fever, anorexia, and weight loss, higher pack-years of smoking and poorer KPS compared to responders. Overall, chemotherapy caused significant decline in the frequency of coughing, dyspnea, chest pain, fever, anorexia, weight loss, and improvement in hemoglobin and albumin levels. There was no significant improvement in pulmonary functions, nutritional status, or QOL scores after treatment. Lung cancer patients have a poor QOL. Although chemotherapy provides significant symptomatic benefit, this does not translate into similar benefit in respiratory and nutritional status or QOL. Patients with constitutional

    To compare the difference in the efficacy on gait time cycle of ischemic stroke between yin-yang respiratory reinforcing and reducing needling technique (yin-yang needling) and the conventional acupuncture. Sixty cases of ischemic stroke were randomized into a conventional acupuncture group and a yin-yang needling group, 30 cases in each one. The basic treatment (the control of blood pressure, blood sugar and blood lipid, the intravenous drops of ginkgo leaf extract and dipyridamole injection and vinpocetine injection) were applied in the two groups. Additionally, in the conventional acupuncture group, the acupoints of the Stomach Meridian of Foot-Yangming [Biguan (ST 31), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), etc.] were selected and stimulated with the even needling technique. In the yin-yang needling group, the acupoints of yin meridians such as Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9) and Sanyinjiao (SP 6), etc. and the acupoints of yang meridians such as Biguan (ST 31), Liangqiu (ST 34) and Yanglingquan (GB 34), etc. were selected. The reducing manipulation of respiratory reinforcing and reducing technique was applied to the acupoints of yin meridians and the reinforcing manipulation was applied to the acupoints of yang meridians. The kinematics time parameters were determined and compared before and 4 weeks after treatment. After treatment, the differences in the gait cycle, the phase time of standing (%), the phase time of single support (%), the phase time of unilateral sway (%) on the affected (healthy) foot and phase time of double support (%) were significant as compared with those before treatment in the patients of the two groups (all P yin-yang needling group were improved much obviously after treatment as compared with those in the conventional acupuncture group. The differences in support phase time (%), single support phase time (%) and sway phase time (%) were significant between the affected limb and

    Intravesical Bacille Calmette-Guérin (BCG) is essential for preventing the recurrence and progression of superficial bladder tumours. The aim of our study was to compare the efficacy and toxicity of the Connaught and Tice strains, as well as the importance of the maintenance regimen. We retrospectively reviewed 110 patients with superficial bladder tumours who underwent adjuvant endovesical treatment. The patients were distributed into 3 groups, based on whether the treatment was with the Connaught strain, the Tice strain or both sequentially. We calculated the relapse-free survival rate in each group and compared the patients who completed the maintenance treatments against those who did not. To identify the predictors of relapse, we performed a multivariate analysis. We also assessed the toxicity by analysing the onset of BCGitis, urinary urgency, fever, urinary tract infection and treatment withdrawing due to adverse effects. We found no differences in the efficacy parameters. The patients in the Connaught group completed the maintenance to a lesser extent (38.4 vs. 72% for the Tice group and 76.3% for both groups; P=.010). The patients who completed the maintenance had better relapse-free survival at 60 months (88.5 vs. 74.2%; P=.036), regardless of the strain employed. The multivariate analysis identified a size larger than 3cm, more than 3 implants and not completing the maintenance as risk factors of relapse. The patients with the Connaught strain had higher rates of BCGitis, with no differences in the other events studied. Completing the maintenance phase is essential, regardless of the strain employed. The Connaught strain has a greater risk of BCGitis, and a sequential regimen could be useful in certain scenarios. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

  13. The importance of masticatory functional analysis in the diagnostic finding and treatment planning for prosthodontic rehabilitation

    Harry Laksono

    2012-06-01

    Full Text Available Background: The masticatory system as a biologic system is subjected to harmful influences of varying severity. Almost half of routine patients requesting prosthodontic treatment indicated at least one sign or symptom of temporomandibular disorders. Analysis of the masticatory system often neglected by dentist. Untreated temporomandibular disorders may significantly implicated in the perpetuation of the disorder and may interfere with routine prosthodontic clinical procedures. It would be resulted unsuccessful long term goal of prosthodontic rehabilitation because of the uncompleted diagnoses and treatment plan. Purpose: The purpose of this case report was to give the information of the importance of masticatory functional analysis in the diagnostic finding for treatment planning in the prosthodontic rehabilitation. Case: A 45 year - old male patient, partial dentate with reduced chewing efficiency, mild pain in right preauricular region in function, left click in opening mouth, severe attrition on all anterior lower teeth with vertical dimension of occlusion decreased due to loss of posterior support. He wanted to make a new denture. Case management: Record and analyze of active and passive mandibular movement, opening pathway, muscle and temporomandibular joints palpation, load testing, and vertical dimension of occlusion with manual functional analysis (MFA, occlusal condition and radiographic examination. Treatment plan was formulated into 3 phases: stabilization of the masticatory system, definitive treatment and periodical control. The result of this treatment excellent for 1 year evaluation after permanent cementation. Conclusion: Masticatory functional analysis is very important and must be done in the diagnosis finding for treatment planning in every case of prosthodontic rehabilitation.Latar belakang: Sistem pengunyahan sebagai sistem biologis sewaktu-waktu dapat terjadi gangguan dengan berbagai derajat keparahan.

  15. Antenatal treatment with corticosteroids for preterm neonates: impact on the incidence of respiratory distress syndrome and intra-hospital mortality

    Joice Fabíola Meneguel

    Full Text Available CONTEXT: Although the benefits of antenatal corticosteroids have been widely demonstrated in other countries, there are few studies among Brazilian newborn infants. OBJECTIVE: To evaluate the effectiveness of antenatal corticosteroids on the incidence of respiratory distress syndrome and intra-hospital mortality among neonates with a gestational age of less than 34 weeks. TYPE OF STUDY: Cross-sectional. SETTING: A tertiary-care hospital. PARTICIPANTS: Neonates exposed to any dose of antenatal corticosteroids for fetal maturation up to 7 days before delivery, and newborns paired by sex, birth weight, gestational age and time of birth that were not exposed to antenatal corticosteroids. The sample obtained consisted of 205 exposed newborns, 205 non-exposed and 39 newborns exposed to antenatal corticosteroids for whom it was not possible to find an unexposed pair. PROCEDURES: Analysis of maternal and newborn records. MAIN MEASUREMENTS: The primary clinical outcomes for the two groups were compared: the incidence of respiratory distress syndrome and intra-hospital mortality; as well as secondary outcomes related to neonatal morbidity. RESULTS: Antenatal corticosteroids reduced the occurrence of respiratory distress syndrome (OR: 0.33; 95% CI: 0.21-0.51 and the protective effect persisted when adjusted for weight, gestational age and the presence of asphyxia (adjusted OR: 0.27; 95% CI: 0.17-0.43. The protective effect could also be detected through the reduction in the need for and number of doses of exogenous surfactant utilized and the number of days of mechanical ventilation needed for the newborns exposed to antenatal corticosteroids. Their use also reduced the occurrence of intra-hospital deaths (OR: 0.51: 95% CI: 0.38-0.82. However, when adjusted for weight, gestational age, presence of prenatal asphyxia, respiratory distress syndrome, necrotizing enterocolitis and use of mechanical ventilation, the antenatal corticosteroids did not maintain the

    Full Text Available Filtering nonwovens produced with melt-blown technology are one of the most basic materials used in the construction of respiratory protective equipment (RPE against harmful aerosols, including bio- and nanoaerosols. The improvement of their filtering properties can be achieved by the development of quasi-permanent electric charge on the fibres. Usually corona discharge method is utilized for this purpose. In the presented study, it was assumed that the low-temperature plasma treatment could be applied as an alternative method for the manufacturing of conventional electret nonwovens for the RPE construction. Low temperature plasma treatment of polypropylene nonwovens was carried out with various process gases (argon, nitrogen, oxygen or air in a wide range of process parameters (gas flow velocity, time of treatment and power supplied to the reactor electrodes. After the modification, nonwovens were evaluated in terms of filtration efficiency of paraffin oil mist. The stability of the modification results was tested after 12 months of storage and after conditioning at elevated temperature and relative humidity conditions. Moreover, scanning electron microscopy and ATR-IR spectroscopy were used to assess changes in surface topography and chemical composition of the fibres. The modification of melt-blown nonwovens with nitrogen, oxygen and air plasma did not result in a satisfactory improvement of the filtration efficiency. In case of argon plasma treatment, up to 82% increase of filtration efficiency of paraffin oil mist was observed in relation to untreated samples. This effect was stable after 12 months of storage in normal conditions and after thermal conditioning in (70 ± 3°C for 24 h. The use of low-temperature plasma treatment was proven to be a promising improvement direction of filtering properties of nonwovens used for the protection of respiratory tract against harmful aerosols.

    Forty patients participated in a study of the importance of early occupational therapy for the prognosis in stable Colles' fractures. Seventeen patients were treated by an occupational therapist 1-3 days after the injury, and the need for appliances and home-care was estimated. Twenty-three patients completed the usual treatment. Five weeks after the injury, we found significantly (p less than 0.05) better function of the hand in the 17 patients with early occupational therapy. This difference in function could not be found after 13 weeks. The rate of complications was the same in the two groups. The results indicate that contact with the occupational therapist shortly after the injury is valuable in patients with stable Colles' fractures.

    2000-09-01

    As part of the European Community Respiratory Health Survey (ECRHS) in 1992-1993 we assessed management practices and treatment perceptions among young asthmatic adults in Melbourne, Australia. We conducted a postal questionnaire survey of 4500 randomly selected adults (aged 20-44 years), drawn from three electoral districts, of whom 3200 (71%) subjects responded. A randomly selected sample of 1642 respondents, 'enriched' by a further 433 symptomatic subjects, was invited to complete a second phase respiratory questionnaire. The questionnaire was completed by 757 subjects who underwent laboratory testing. A further 119 subjects who were unable to attend the laboratory completed an identical questionnaire by telephone interview (42% response rate). In the second phase, 16% of subjects reported 'current asthma' (group I) as defined by physician confirmation and a recent attack (within 1 year), 10% had confirmed asthma but reported no recent attack (group II) and 74% did not have asthma (group III). Inhaled corticosteroid use was significantly higher in group I than in group II subjects (45% vs 24%, Ptime. Despite national education campaigns, the majority of young asthmatic adults in Melbourne did not adhere to prescribed treatment, but continued to rely upon beta2-agonists alone with neglect of regular inhaled corticosteroid which has probably contributed to Australia's continued high asthma morbidity and mortality rates.

    Interprofessional collaboration is the process in which different professional groups work together to positively impact health care. We aimed to explore physicians' attitudes toward interprofessional collaboration in the context of chronic pain management with the implication that if attitudes are not positive, appropriate interventions could be developed. A quantitative attitudes study. The ethical committee approved the study. A web-based survey about interprofessional treatment of chronic pain was administered to physicians. Outcome measures were as follows: physicians' demographic and workplace information, previous experience of working within an interprofessional team, and attitudes towards interprofessional collaboration in chronic pain management. There were 90 physicians who responded to the survey. Physicians had positive attitudes towards team work in the context of chronic pain, but they were undecided about sharing their role within an interprofessional team. The family physician was singled out as the most important as well as the most common collaborator in chronic pain treatment. Interprofessional educational seminars and workshops were suggested as methods for improving interprofessional collaboration. Interprofessional collaboration may be enhanced with continuing medical education that will bring together different healthcare professionals, enable them to exchange experiences and learn about their potential roles within a team. © 2012 Nordic College of Caring Science.

    Globally, over 4% of the world population is affected by hepatitis C virus (HCV) infection. The current standard of care for hepatitis C infection is combination therapy with pegylated interferon and ribavirin for 48 weeks, which yield a sustained virological response in only a little over half of the patients with genotype 1 HCV. We investigated the clinical importance of pharmacogenetics in treatment efficacy and prediction of hematotoxicity. A total of 148 patients infected with HCV were enrolled. All patients were treated for a period of 48 weeks or less with pegylated interferon and ribavirin. Four genotypes were investigated: inosine triphosphatase (ITPA) rs1127354, C20orf194 rs6051702, interferon lambda (IFNL)3 rs8099917, IFNL3÷4 rs12979860 in the population from southwestern Romania. Genetic variants for rs129798660 and rs6051702 proved once more to represent an indisputable clinical tool for predicting sustained virological response (SVR) (69.23%, chi-square p=0.007846, ppharmacogenetics should play a constant role in treatment decisions for patients infected with hepatitis C virus.

A 6-year-old boy diagnosed with ADHD was prescribed methylphenidate 5 mg twice daily (7 am and noon and the family was compliant with administration of this medication. On the first day of treatment, the patient had an adverse reaction, becoming disobedient, more mischievous, erratic, resistant to discipline, would not go to sleep until midnight, and had a poor appetite. The All-In-One PGX (All-In-One Pharmacogenetics for Antipsychotics test for CYP2D6, CYP2C19, and CYP2C9 was performed using microarray-based and real-time polymerase chain reaction techniques. The genotype of our patient was identified to be CYP2D6*2/*10, with isoforms of the enzyme consistent with a predicted cytochrome P450 2D6 intermediate metabolizer phenotype. Consequently, the physician adjusted the methylphenidate dose to 2.5 mg once daily in the morning. At this dosage, the patient had a good response without any further adverse reactions. Pharmacogenetic testing should be included in the management plan for ADHD. In this case, cooperation between the medical team and the patients' relatives was key to successful treatment.Keywords: attention deficit hyperactive disorder, pharmacogenomics, CYP2D6, adverse drug reactions, dose adjustment, intermediate metabolizer

  2. Importance of the neutrons kerma coefficient in the planning of Brachytherapy treatments with Cf-252 sources

    2006-01-01

    The Cf-252 is a fast neutrons emitting radioisotope by spontaneous fission that can be used as sealed source in medicine applications, industry and research. Commercially its offer sources of different sizes, compact and with a fast neutrons emission of the order of 10 6 n/s-μg and an energy spectra that presents respectively maxim and average energy in 2.1 MeV and 0.7 MeV. In medicine new applications are being developed for the treatment of patient with hypoxic and voluminous tumors, where the therapy with photons has not given positive results, as well as for the protocols of therapy treatment by boron neutron capture, where very small sources of Cf-252 will be used with the interstitial brachytherapy technique of high and low dose rate. In this work an analysis of how the small differences that exist in the elementary composition of 4 wicked tumors, 4 ICRU healthy tissues and 3 substitute materials of ICRU tissue used in dosimetry are presented, its generate changes in the neutrons kerma coefficient in function of the energy and consequently in the absorbed dose in the interval of 11 eV to 29 MeV. These differences can produce maximum variations of the neutron kerma coefficients ratio for E n > 1 keV of the one: 15% tumor/ICRU guest healthy tissue, 12% ICRU tumor/muscle, 12% ICRU healthy tissues ICRU/ICRU muscle, 22% substitutes tissue/tumor and 22% ICRU substitutes tissue/muscle. Also, it was found that the average value of the neutrons kerma coefficient for the 4 wicked tumors is from 6% to 7% smaller that the average value for the soft tissue in the interval energy of interest for therapy with fast neutrons with E n > 1 MeV. These results have a special importance during the planning process of brachytherapy treatments with sources of 252 Cf, to optimize and to individualize the patients treatments. (Author)

    Campylobacter spp. can be pathogenic to humans and often harbor antimicrobial resistance genes. Data on resistance in relation to fluoroquinolone use in beef cattle are scarce. This cross-sectional study of preharvest cattle evaluated Campylobacter prevalence and susceptibility to nalidixic acid and ciprofloxacin in feedlots that previously administered a fluoroquinolone as primary treatment for bovine respiratory disease. Twenty fresh fecal samples were collected from each of 10 pens, in each of five feedlots, 1-2 weeks before harvest. Feces were cultured for Campylobacter using selective enrichment and isolation methods. Genus and species were confirmed via PCR. Minimum inhibitory concentrations (MICs) of ciprofloxacin and nalidixic acid were determined using a micro-broth dilution method and human breakpoints. Antimicrobial use within each pen was recorded. Data were analyzed using generalized linear mixed-models (prevalence) and survival analysis (MICs). Overall, sample-level prevalence of Campylobacter was 27.2% (272/1000) and differed significantly among feedlots (p feedlot (p = 0.03). The MICs for the majority of Campylobacter isolates were above the breakpoints for nalidixic acid (68.4%; 175/256) and for ciprofloxacin (65.6%; 168/256). Distributions of MICs for nalidixic acid (p ≤ 0.01) and ciprofloxacin (p ≤ 0.05) were significantly different among feedlots, and by Campylobacter species. However, fluoroquinolone treatments, sex, body weight, days on feed, and metaphylaxis were not significantly associated with MIC distributions within pens. We found no evidence that the number of fluoroquinolone treatments within feedlot pens significantly affected the within-pen fecal prevalence or quinolone susceptibilies of Campylobacter in feedlots that used a fluoroquinolone as primary treatment for bovine respiratory disease.

  4. Respiratory mechanics to understand ARDS and guide mechanical ventilation.

    Mauri, Tommaso; Lazzeri, Marta; Bellani, Giacomo; Zanella, Alberto; Grasselli, Giacomo

    2017-11-30

    As precision medicine is becoming a standard of care in selecting tailored rather than average treatments, physiological measurements might represent the first step in applying personalized therapy in the intensive care unit (ICU). A systematic assessment of respiratory mechanics in patients with the acute respiratory distress syndrome (ARDS) could represent a step in this direction, for two main reasons. Approach and Main results: On the one hand, respiratory mechanics are a powerful physiological method to understand the severity of this syndrome in each single patient. Decreased respiratory system compliance, for example, is associated with low end expiratory lung volume and more severe lung injury. On the other hand, respiratory mechanics might guide protective mechanical ventilation settings. Improved gravitationally dependent regional lung compliance could support the selection of positive end-expiratory pressure and maximize alveolar recruitment. Moreover, the association between driving airway pressure and mortality in ARDS patients potentially underlines the importance of sizing tidal volume on respiratory system compliance rather than on predicted body weight. The present review article aims to describe the main alterations of respiratory mechanics in ARDS as a potent bedside tool to understand severity and guide mechanical ventilation settings, thus representing a readily available clinical resource for ICU physicians.

    To moving lung tumors, we applied a respiratory-gated strategy to carbon-ion pencil beam scanning with multiple phase-controlled rescanning (PCR). In this simulation study, we quantitatively evaluated dose distributions based on 4-dimensional CT (4DCT) treatment planning. Volumetric 4DCTs were acquired for 14 patients with lung tumors. Gross tumor volume, clinical target volume (CTV) and organs at risk (OARs) were delineated. Field-specific target volumes (FTVs) were calculated, and 48Gy(RBE) in a single fraction was prescribed to the FTVs delivered from four beam angles. The dose assessment metrics were quantified by changing the number of PCR and the results for the ungated and gated scenarios were then compared. For the ungated strategy, the mean dose delivered to 95% of the volume of the CTV (CTV-D95) was in average 45.3 ± 0.9 Gy(RBE) even with a single rescanning (1 × PCR). Using 4 × PCR or more achieved adequate target coverage (CTV-D95 = 46.6 ± 0.3 Gy(RBE) for ungated 4 × PCR) and excellent dose homogeneity (homogeneity index =1.0 ± 0.2% for ungated 4 × PCR). Applying respiratory gating, percentage of lung receiving at least 20 Gy(RBE) (lung-V20) and heart maximal dose, averaged over all patients, significantly decreased by 12% (p lung tumors without gating. The use of a respiratory-gated strategy in combination with PCR reduced excessive doses to OARs.

    Full Text Available Christopher Zammit, Helen Liddicoat, Ian Moonsie, Himender MakkerSleep and Ventilation Unit, Department of Respiratory Medicine, North Middlesex University Hospital, London, UKAbstract: The obesity epidemic is a global problem, which is set to increase over time. However, the effects of obesity on the respiratory system are often underappreciated. In this review, we will discuss the mechanical effects of obesity on lung physiology and the function of adipose tissue as an endocrine organ producing systemic inflammation and effecting central respiratory control. Obesity plays a key role in the development of obstructive sleep apnea and obesity hypoventilation syndrome. Asthma is more common and often harder to treat in the obese population, and in this study, we review the effects of obesity on airway inflammation and respiratory mechanics. We also discuss the compounding effects of obesity on chronic obstructive pulmonary disease (COPD and the paradoxical interaction of body mass index and COPD severity. Many practical challenges exist in caring for obese patients, and we highlight the complications faced by patients undergoing surgical procedures, especially given the increased use of bariatric surgery. Ultimately, a greater understanding of the effects of obesity on the respiratory disease and the provision of adequate health care resources is vital in order to care for this increasingly important patient population.Keywords: obesity, lung function, obstructive sleep apnea, obesity hypoventilation syndrome, anesthesia

  7. SU-E-P-41: Imaging Coordination of Cone Beam CT, On-Board Image Conjunction with Optical Image Guidance for SBRT Treatment with Respiratory Motion Management

    Liu, Y; Campbell, J

    2015-01-01

    Purpose: To spare normal tissue for SBRT lung/liver patients, especially for patients with significant tumor motion, image guided respiratory motion management has been widely implemented in clinical practice. The purpose of this study was to evaluate imaging coordination of cone beam CT, on-board X-ray image conjunction with optical image guidance for SBRT treatment with motion management. Methods: Currently in our clinic a Varian Novlis Tx was utilized for treating SBRT patients implementing CBCT. A BrainLAB X-ray ExacTrac imaging system in conjunction with optical guidance was primarily used for SRS patients. CBCT and X-ray imaging system were independently calibrated with 1.0 mm tolerance. For SBRT lung/liver patients, the magnitude of tumor motion was measured based-on 4DCT and the measurement was analyzed to determine if patients would be beneficial with respiratory motion management. For patients eligible for motion management, an additional CT with breath holding would be scanned and used as primary planning CT and as reference images for Cone beam CT. During the SBRT treatment, a CBCT with pause and continuing technology would be performed with patients holding breath, which may require 3–4 partially scanned CBCT to combine as a whole CBCT depending on how long patients capable of holding breath. After patients being setup by CBCT images, the ExactTrac X-ray imaging system was implemented with patients’ on-board X-ray images compared to breath holding CT-based DRR. Results: For breath holding patients SBRT treatment, after initially localizing patients with CBCT, we then position patients with ExacTrac X-ray and optical imaging system. The observed deviations of real-time optical guided position average at 3.0, 2.5 and 1.5 mm in longitudinal, vertical and lateral respectively based on 35 treatments. Conclusion: The respiratory motion management clinical practice improved our physician confidence level to give tighter tumor margin for sparing normal

    The aim of this research into 'self-management' was to determine to what extent respondents were aware of their status as overweight or obese. For respondents who indicated that they were overweight or obese, the goal was to determine whether they tried to lose weight, what steps they took to control their, and what specific methods they used. Information was collected using semi-structured interviews from May 31, 2014, to January 30, 2015. Data processing was performed using statistical analysis of the social data SASDM 01/04/10 software. The total study group consisted of 600 respondents, including 302 from the Roma minority, and 298 from the non-Roma majority population (control group). Respondents were selected specifically from South Bohemia Region of the Czech Republic. The sample from the Roma minority was constructed using the snowball method (Snowball Sampling). The control sample of non-Roma was selected through quota sampling. The results indicate that the respondents from both the Roma minority and the non-Roma control group generally recognized when they were overweight or obese, or they were aware of it to a much lesser extent than objective indicators revealed. More than two thirds of the respondents who admitted they were overweight or obese (N = 143) reported that they had suffered from overweight or obesity since they were young adults. Significantly more members of the majority population had tried to lose weight using self-management, whereas the level of effort was significantly less among members of the Roma minority (P = 0). Nevertheless, Roma respondents significantly more often reported (P < 0.01) that they had agreed on a specific weight loss plan with a doctor. The results of our research show that in the context of prevention, it is important to promote self-managed skills, habits and other characteristics that can play an important role in the prevention and treatment of obesity and overweight.

  10. Treatment of Anorexia Nervosa: The Importance of Disease Progression in the Prognosis.

    Andrade, Rodrigo; Gonçalves-Pinho, Manuel; Roma-Torres, António; Brandão, Isabel

    2017-08-31

    Anorexia nervosa is a severe, usually chronic, life-threatening disease of complex etiology characterized by food restriction, overestimation of the importance of body weight and image, intense fear of weight gain and distortion of body image. Anorexia nervosa is associated with high rates of mortality, suicide and decreased quality of life. Our aim is to present an anorexia nervosa treatment program offered in a major university hospital in Portugal, and to determine the impact of illness duration before admission on the outcome. Our hypothesis is that patients with greater disease longevity may have worse prognosis and poorer outcome. The sample included data from case records of 169 patients seen consecutively and for the first time at Centro Hospitalar São João, between 2010 and 2015. We performed a retrospective observational study which included data collected at admission and from later follow-up years. From the initially selected patients, 14.8% reached total remission, 16% accomplished partial remission and 14.2% ended up with exacerbation/stagnation of the disease. The dropout rate was of 55% throughout our study period. We found significant differences on outcome rates between distinct illness duration groups (p = 0.007). There are several factors frequently associated with poor outcome for anorexia nervosa. The interpretation of outcome findings was limited by the high rate of dropout and lack of consistent definition criteria. Our results support the idea that illness duration has an important role on the outcome and prognostic features of these patients.

    Tattoo is going to be a very common practice especially among young people and we are witnessing a gradual increase of numerous potential complications to tattoo placement which are often seen by physicians, but generally unknown to the public. The most common skin reactions to tattoo include a transient acute inflammatory reaction due to trauma of the skin with needles and medical complications such as superficial and deep local infections, systemic infections, allergic contact dermatitis, photodermatitis, granulomatous and lichenoid reactions, and skin diseases localized on tattooed area (eczema, psoriasis, lichen, and morphea). Next to these inflammatory skin reactions we have to consider also the possibility of the development of cutaneous conditions such as pseudolymphomatous reactions and pseudoepitheliomatous hyperplasia. The aim of this study is to underline the importance of an early diagnosis by performing a histological examination especially when we are in front of suspected papulonodular lesions arising from a tattoo, followed by a proper treatment, since cutaneous neoplastic evolution is known to be a rare but possible complication.

  12. Alkaloids as important scaffolds in therapeutic drugs for the treatments of cancer, tuberculosis, and smoking cessation.

    Kittakoop, Prasat; Mahidol, Chulabhorn; Ruchirawat, Somsak

    2014-01-01

    Alkaloid molecules can act, depending on a type of amine functionality present in alkalods, as either hydrogenacceptor or hydrogen-donor for hydrogen bonding that is critically important for the interaction (binding) between targets (enzymes, proteins and receptors) and drugs (ligands). Because of this unique property, alkaloid scaffolds are therefore present in several drugs and lead compounds. This review highlights alkaloid scaffolds in drugs, particularly those recently approved in 2012; it also covers the scaffolds in leads and drug candidates which are in clinical trials and preclinical pipeline. The review focuses on three therapeutic areas including treatments of cancer, tuberculosis, and tobacco cessation. Alkaloid scaffolds in drugs and leads are inspired by those of naturally occurring alkaloids, and these scaffolds include pyridine, piperidine, quinoline, quinolinone, quinazoline, isoquinoline, indole, indolinone, isoindole, isoxazole, imidazole, indazole, thiazole, pyrazole, oxazolidinone, oxadiazole, and benzazepine. In addition to medicinal chemistry aspects, natural products possessing an individual alkaloid scaffold, as well as the mechanism of action of drugs and leads, are also discussed in this review.

    To pre-establish an alternative technique to the toxic fumigant, methyl bromide which is the current quarantine measure of agricultural products for export and import, some selected agricultural products, such as chestnut, acorn, red bean and mung bean, were subjected to a preliminary study to confirm the comparative effects of gamma irradiation and MBr fumigant on their disinfestation and quality, thereby preparing the basic data for the practical approach. Current quarantine activities were examined and the related limitations were investigated. Quarantine-related pests were investigated on their radiosensitivity and disinfestation effects by both treatments. The pests in chestnut and acorn, Curculio skkimensis Heller, Curculio dentipes Roelofs, and Dichocrocis punctiferalis Guenee showed an increased mortality when exposed to above 0.5 kGy irradiation, resulting in 100% of mortality three weeks later. Callosobruchus chinensis Linne from both red and mung beans revealed a apparent mortality at around 10 days after irradiation of 1 to 3 kGy. Current fumigation was perfect in its disinfesting capability, but it caused the detrimental effects on physical quality of agricultural produce. Whereas, irradiation doses suitable for controlling the pests did not induce any significant changes in the quality of the samples. (author). 53 refs., 74 figs., 138 tabs.

    2015-12-14

    Acinetobacter baumannii has emerged as a notorious multidrug-resistant pathogen, and development of novel control measures is of the utmost importance. Understanding the factors that play a role in drug resistance may contribute to the identification of novel therapeutic targets. Pili are essential for A. baumannii adherence to and biofilm formation on abiotic surfaces as well as virulence. In the present study, we found that biofilm formation was significantly induced in an imipenem-resistant (Imp(r)) strain treated with a subinhibitory concentration of antibiotic compared to that in an untreated control and an imipenem-susceptible (Imp(s)) isolate. Using microarray and quantitative PCR analyses, we observed that several genes responsible for the synthesis of type IV pili were significantly upregulated in the Imp(r) but not in the Imp(s) isolate. Notably, this finding is corroborated by an increase in the motility of the Imp(r) strain. Our results suggest that the ability to overproduce colonization factors in response to imipenem treatment confers biological advantage to A. baumannii and may contribute to clinical success.

  15. The Importance of Diet and Gut Health to the Treatment and Prevention of Mental Disorders.

    Dawson, S L; Dash, S R; Jacka, F N

    2016-01-01

    The departure from traditional lifestyles and the rising disease burden of mental disorders are increasing global health concerns. Changes in diet around the world mean that populations are now increasingly reliant on highly processed, poor quality foods, which have been linked to increased risk for mental disorder. Conversely, a nutrient-rich diet is understood to be protective of mental health, and researchers are now aiming to understand the biological underpinnings of this relationship. The gut microbiota has been proposed as a key mediator of this link, given its association with both diet and mental health. Importantly, several critical "windows of opportunity" for prevention and intervention have been identified, particularly early life and adolescence; these are periods of rapid development and transition that provide a foundation for future health. Strategies that promote overall diet quality, high in fiber and nutrients, have been linked to increased microbial diversity and gut health. Improving diet quality and subsequent gut health may have benefits for individuals' mental health, as well as the mental health of future generations. Here we discuss specific, targeted dietary and gut focused strategies for the prevention and treatment of mental disorder. © 2016 Elsevier Inc. All rights reserved.

    Auscultation of the lung is an important part of the respiratory examination and is helpful in diagnosing various respiratory disorders. Auscultation assesses airflow through the trachea-bronchial tree. It is important to distinguish normal respiratory sounds from abnormal ones for example crackles, wheezes, and pleural rub in order to make correct diagnosis. It is necessary to understand the underlying pathophysiology of various lung sounds generation for better understanding of disease processes. Bedside teaching should be strengthened in order to avoid erosion in this age old procedure in the era of technological explosion. PMID:26229557

    To identify effective treatments and risk factors associated with death rattle in adults at the end of life. The presence of noisy, pooled respiratory tract secretions is among the most common symptoms in dying patients around the world. It is unknown if "death rattle" distresses patients, but it can distress relatives and clinicians. Treatments appear unsatisfactory, so prophylaxis would be ideal if possible. Quantitative systematic review and narrative summary following Cochrane Collaboration guidelines. CINAHL, MEDLINE, Health Source Nursing and Web of Science were searched for international literature in any language published from 1993 - 2016 using MeSH headings and iterative interchangeable terms for "death rattle". Randomized controlled trials were appraised using the Cochrane Collaboration's tool for assessing risk of bias. Non-randomized studies were assessed using ROBINS-I tool for assessing risk of bias in non-randomized studies of interventions. Instances of treatment and risk were extracted and relevant key findings extracted in line with Cochrane methods. Five randomized trials and 23 non-randomized studies were analysed. No pharmacological or non-pharmacological treatment was found superior to placebo. There was a weak association between lung or brain metastases and presence of death rattle, but otherwise inconsistent empirical support for a range of potential risk factors. Clinicians have no clear evidence to follow in either treating death rattle or preventing it occurring. However, several risk factors look promising candidates for prospective analysis, so this review concludes with clear recommendations for further research. © 2018 John Wiley & Sons Ltd.

  20. Acute Respiratory Distress due to Thymoma in a Patient Treated with TK Inhibitor: A Case Report and Review of the Current Treatment Options

    2011-03-01

    Full Text Available Thymic malignancies are rare intrathoracic tumors that may be aggressive and difficult to treat in advanced stage. Surgery is the cornerstone of the management of thymomas: it is significant for the definite histopathological diagnosis and staging, and in most cases, it constitutes the first step of the treatment strategy. For patients with primary unresectable thymomas, the multimodal treatment schedule nowadays includes neoadjuvant chemotherapy, extensive surgery, adjuvant radiotherapy, and in some cases, adjuvant chemotherapy. A patient with a history of stage III COPD and an undiagnosed thoracic mass was admitted to the intensive care unit with acute respiratory distress. A radiologic evaluation by CT scan revealed a mass of 13 cm in diameter at the mediastinum. Fine needle aspiration was performed and revealed a thymoma. Due to poor performance status, the patient was not able to undergo surgery. He refused to be treated with neither chemotherapy nor radiotherapy, but due to EGFR overexpression, treatment with TK inhibitor was suggested. Fine needle aspiration biopsy is commonly used to identify metastasis to the mediastinum. However, it is less often employed as a primary diagnostic tool for tumors, particularly thymic neoplasms. The use of targeted therapies for the treatment of thymic malignancies has been described in the literature. Over the past years, significant efforts have been made to dissect the molecular pathways involved in the carcinogenesis of these tumors. Insights have been obtained following anecdotal clinical responses to targeted therapies, and large-scale genomic analyses have been conducted.

  1. Neuraminidase treatment of respiratory syncytial virus-infected cells or virions, but not target cells, enhances cell-cell fusion and infection

    Barretto, Naina; Hallak, Louay K.; Peeples, Mark E.

    2003-01-01

    Respiratory syncytial virus (RSV) infection of HeLa cells induces fusion, but transient expression of the three viral glycoproteins induces fusion poorly, if at all. We found that neuraminidase treatment of RSV-infected cells to remove sialic acid (SA) increases fusion dramatically and that the same treatment of transiently transfected cells expressing the three viral glycoproteins, or even cells expressing the fusion (F) protein alone, results in easily detectable fusion. Neuraminidase treatment of the effector cells, expressing the viral glycoproteins, enhanced fusion while treatment of the target cells did not. Likewise, infectivity was increased by treating virions with neuraminidase, but not by treating target cells. Reduction of charge repulsion by removal of the negatively charged SA is unlikely to explain this effect, since removal of negative charges from either membrane would reduce charge repulsion. Infection with neuraminidase-treated virus remained heparan-sulfate-dependent, indicating that a novel attachment mechanism is not revealed by SA removal. Interestingly, neuraminidase enhancement of RSV infectivity was less pronounced in a virus expressing both the G and the F glycoproteins, compared to virus expressing only the F glycoprotein, possibly suggesting that the G protein sterically hinders access of the neuraminidase to its fusion-enhancing target

    2016-09-01

    Dysphagia and regurgitation are considered typical symptoms of achalasia. However, there is mounting evidence that some achalasia patients may also experience respiratory symptoms such as cough, wheezing, and hoarseness. The aims of this study were to determine: (1) what percentage of achalasia patients experience respiratory symptoms and (2) the effect of a laparoscopic Heller myotomy and Dor fundoplication on the typical and respiratory symptoms of achalasia. Between May 2008 and December 2015, 165 patients with achalasia were referred for treatment to the Center for Esophageal Diseases of the University of Chicago. Patients had preoperatively a barium swallow, endoscopy, and esophageal manometry. All patients underwent a Heller myotomy and Dor fundoplication. Based on the presence of respiratory symptoms, patients were divided into two groups: group A, 98 patients (59%) without respiratory symptoms and group B, 67 patients (41%) with respiratory symptoms. The preoperative Eckardt score was similar in the two groups (6.5 ± 2.1 versus 6.4 ± 2.0). The mean esophageal diameter was 27.7 ± 10.8 mm in group A and 42.6 ± 20.1 mm in group B (P myotomy that extended for 5 cm on the esophagus and 2.5 cm onto the gastric wall. At a median postoperative follow-up of 17 months, the Eckardt score improved significantly and similarly in the two groups (0.3 ± 0.8 versus 0.3 ± 1.0). Respiratory symptoms improved or resolved in 62 patients (92.5%). The results of this study showed that: (1) respiratory symptoms were present in 41% of patients; (2) patients with respiratory symptoms had a more dilated esophagus; and (3) surgical treatment resolved or improved respiratory symptoms in 92.5% of patients. This study underlines the importance of investigating the presence of respiratory symptoms along with the more common symptoms of achalasia and of early treatment before lung damage occurs.

  6. Combination PPARγ and RXR Agonist Treatment in Melanoma Cells: Functional Importance of S100A2

    Joshua P. Klopper

    2010-01-01

    Full Text Available Nuclear hormone receptors, including RXR and PPARγ, represent novel therapeutic targets in melanoma. We have previously shown that the DRO subline of the amelanotic melanoma A375 responds to rexinoid and thiazolidinedione (TZD treatment in vitro and in vivo. We performed microarray analysis of A375(DRO after TZD and combination rexinoid/TZD treatment in which the calcium binding protein S100A2 had increased expression after rexinoid or TZD treatment and a synergistic increase to combination treatment. Increased S100A2 expression is dependent on an intact PPARγ receptor, but it is not sufficient to mediate the antiproliferative effects of rexinoid/TZD treatment. Over expression of S100A2 enhanced the effect of rexinoid and TZD treatment while inhibition of S100A2 expression attenuated the response to rexinoid/TZD treatment, suggesting that S100A2 is necessary for optimal response to RXR and PPARγ activation by respective ligands. In summary, we have identified potential downstream mediators of rexinoid and TZD treatment in a poorly differentiated melanoma and found that alterations in S100A2 expression affect RXR and PPARγ signaling in A375(DRO cells. These studies provide insight into potential mechanisms of tumor response or resistance to these novel therapies.

    2009-11-01

    A dose titration and reduced duration medication study were performed to evaluate the current enrofloxacin treatment schedule in growing turkeys experimentally infected with avian metapneumovirus and Ornithobacterium rhinotracheale. Experimental groups of 17 four-week-old turkeys were first infected with avian metapneumovirus and 3 d later with O. rhinotracheale. Enrofloxacin treatment in the drinking water was started 24 h after O. rhinotracheale inoculation. In the dose titration study, enrofloxacin doses of 5, 10, and 20 mg/kg of BW were administered for 5 successive days. In the reduced duration medication study, the following enrofloxacin regimens were compared: 25 mg/kg of BW per day on d 0 and 2; 15 mg/kg of BW per day on d 0, 2, and 4; and 10 mg/kg of BW for 5 successive days. In both studies, all enrofloxacin treatments were equally efficacious (i.e., equally capable of shortening the course of clinical disease), eliminating O. rhinotracheale from the respiratory tract and reducing gross lesions. Ornithobacterium rhinotracheale bacteria were not recovered from any of the birds on enrofloxacin-supplemented media, indicating that none of the used treatment regimens promoted the selection of bacterial clones with reduced susceptibility or resistance to this antimicrobial agent. In conclusion, none of the alternative enrofloxacin treatment regimens yielded better results than the current prescribed treatment (i.e., 10 mg/kg of BW for 5 successive days) of O. rhinotracheale infections in turkeys. However, the reduced duration of application would offer a less time-consuming and equally effective alternative.

    Full Text Available The paper an attempt has been made to analysis the status of acute respiratory tract infection among children in India. In the present study we aimed to present first time the detection of viruses, bacteria and mix infection of viruses and bacteria in hospitalized children with ARI and also to analyze the influence of socioeconomic status of parent in two divergent geographical settings of Odisha. Hospitalized children with ARI aged <5 were recruited from July 2014 to June 2015. Nasopharyngeal/Oropharyngial swabs were collected for detection of common respiratory viruses by reverse transcriptase chain reaction (RT-PCR. Bacteria were isolated by routine culture methods. Bivitiate analysis including chi square was used as test of significance. The analysis revealed 150 (56% were detected with ≥1 bacteria, 40 (15% with ≥ 1virus, 22 (8.2% with ≥ 2 bacteria and 20 (7-4% with both bacteria and virus. Most frequently detected pathogens were Klebsiella pneumonae (18.3%, Sptrptococcus pneumonae (12.7%, Parainfluenza A (36.6% and Influenza- A18 (30%. Incidences of pathogens were detected more among children <1 year, Gender discrimination in the form of dietary neglect of the female children has also been noted mostly in case of tribal patients. The present study had identified low socioeconomic status, poor housing conditions, illiterate mothers, birth weight, tobacco smoking families and nutritional status as important determinants for ARI. Interventions to improve these modifiable risk factors can significantly reduce the ARI burden among children especially in tribal population.

    Skin infections account for a high disease burden in indigenous children living in northern Australia. Although the relationship between impetigo and scabies is recognized, the prevalence of scabies in children with impetigo is not well reported. We report the prevalence, demographics and treatment success outcomes of impetigo and scabies coinfection in indigenous children who were participants in a randomized controlled trial of impetigo treatment conducted in remote communities of the Northern Territory, Australia. Of 1715 screening episodes for impetigo, 508 children were randomized to receive intramuscular benzathine benzylpenicillin (BPG), twice daily co-trimoxazole (SXT) for 3 days (4 mg/kg trimethoprim plus 20 mg/kg sulfamethoxazole per dose) or once daily SXT for 5 days (8 mg/kg trimethoprim plus 40 mg/kg sulfamethoxazole per dose). A clinical diagnosis of scabies; tinea of the skin, scalp or nail; and head lice was made on all children. Scabies presence was not confirmed using diagnostic scrapings. In a post-hoc analysis, we determined whether coinfection with scabies had an impact on treatment success for impetigo. Of children randomized to receive treatment for impetigo, 84 of 508 (16.5%) had scabies. The presence of scabies ranged from 14.3% to 20.0% in the 3 treatment groups. Treatment success for impetigo with and without scabies coinfection, independent of the treatment groups, was 75.9% and 86.6%, respectively, absolute difference 10.7% [95% confidence interval (CI): +1% to +21%]. Treatment success for impetigo with and without scabies coinfection in the BPG group was 69.6% and 88.0%, respectively, absolute difference 18.4% (95% CI: -1% to +38%). In the pooled SXT groups, the treatment success for impetigo with and without scabies coinfection was 78.6% and 86.0%, respectively, with absolute difference 7.4% (95% CI: -4% to +18%). Treatment success in the pooled SXT group with scabies (78.6%) was higher than in the BPG group (69.6%) with scabies

    To evaluate associations between economic and performance outcomes with the number of treatments after an initial diagnosis of bovine respiratory disease (BRD) in commercial feedlot cattle. 212,867 cattle arriving in a Midwestern feedlot between 2001 and 2006. An economic model was created to estimate net returns. Generalized linear mixed models were used to determine associations between the frequency of BRD treatments and other demographic variables with economic and performance outcomes. Net returns decreased with increasing number of treatments for BRD. However, the magnitude depended on the season during which cattle arrived at the feedlot, with significantly higher returns for cattle arriving during fall and summer than for cattle arriving during winter and spring. For fall arrivals, there were higher mean net returns for cattle that were never treated ($39.41) than for cattle treated once ($29.49), twice ($16.56), or ≥ 3 times (-$33.00). For summer arrivals, there were higher least squares mean net returns for cattle that were never treated ($31.83) than for cattle treated once ($20.22), twice ($6.37), or ≥ 3 times ($-42.56). Carcass traits pertaining to weight and quality grade were deemed responsible for differences in net returns among cattle receiving different numbers of treatments after an initial diagnosis of BRD. Differences in economic net returns and performance outcomes for feedlot cattle were determined on the basis of number of treatments after an initial diagnosis of BRD; the analysis accounted for the season of arrival, sex, and weight class.

    The purpose of this study was to evaluate the usefulness of respiratory-gated positron emission tomography (4D-PET) in pancreatic cancer radiotherapy treatment planning (RTTP). Fourteen patients with 18F-fluorodeoxyglucose (FDG)-avid pancreatic tumours were evaluated between December 2013 and March 2015. Two sets of volumes were contoured for the pancreatic tumour of each patient. The biological target volume in three-dimensional RTTP (BTV3D) was contoured using conventional respiratory un-gated PET. The BTV3D was then expanded using population-based margins to generate a series of internal target volume 3D (ITV3D) values. The ITV 4D (ITV4D) was contoured using 4D-PET. Each of the five phases of 4D-PET was used for 4D contouring, and the ITV4D was constructed by summing the volumes defined on the five individual 4D-PET images. The relative volumes and normalized volumetric overlap were computed between ITV3D and ITV4D. On average, the FDG-avid tumour volumes were 1.6 (range: 0.8-2.3) fold greater in the ITV4D than in the BTV3D. On average, the ITV3D values were 2.0 (range: 1.1-3.4) fold larger than the corresponding ITV4D values. The ITV generated from 4D-PET can be used to improve the accuracy or reduce normal tissue irradiation compared with conventional un-gated PET-based ITV. Copyright © 2016 Elsevier Ireland Ltd.

    2009-08-01

    Training studies frequently use maximum inspiratory mouth occlusion pressure (PImax) as a therapeutic target and surrogate marker. For patients on beta-blocker (BBL), prognostic data allowing this extrapolation do not exist. Furthermore, the effects of BBL, mainstay of modern chronic heart failure therapy, on respiratory muscle function remain controversial. Finally, no proper separate cutoff according to treatment exists. Prospective, observational inclusion of patients with stable systolic chronic heart failure and recording of 1 year and all-time mortality for endpoint analysis. In 686 patients, 81% men, 494 patients on BBL, PImax was measured along with clinical evaluation. The median follow-up was 50 months (interquartile range: 26-75 months). Patients with or without BBL did not differ significantly for PImax, percentage of predicted PImax or other marker of disease severity. PImax was a significant (hazard ratio: 0.925; 95% confidence interval: 0.879-0.975; chi(2): 8.62) marker of adverse outcome, independent of BBL-status or aetiology. Percentage of predicted PImax was not independent of PImax. The cutoff identified through receiver-operated characteristics for 1-year mortality was 4.14 kPa for patients on BBL and 7.29 kPa for patients not on BBL. When separated accordingly, 1-year mortality was 8.5 versus 21.4%, P=0.02, for patients not on BBL and 4.3 versus 16.2%, P<0.001, for patients on BBL. This study fills the gap between trials targeting respiratory muscle on a functional basis and the resultant prognostic information with regard to BBL. BBL lowered the optimal PImax cutoff values for risk stratification without changing the measured values of PImax. This should be considered at inclusion and evaluation of trials and interpretation of exercise parameters.

  16. Advances in Diagnosis of Respiratory Diseases of Small Ruminants

    2014-01-01

    Full Text Available Irrespective of aetiology, infectious respiratory diseases of sheep and goats contribute to 5.6 percent of the total diseases of small ruminants. These infectious respiratory disorders are divided into two groups: the diseases of upper respiratory tract, namely, nasal myiasis and enzootic nasal tumors, and diseases of lower respiratory tract, namely, peste des petits ruminants (PPR, parainfluenza, Pasteurellosis, Ovine progressive pneumonia, mycoplasmosis, caprine arthritis encephalitis virus, caseous lymphadenitis, verminous pneumonia, and many others. Depending upon aetiology, many of them are acute and fatal in nature. Early, rapid, and specific diagnosis of such diseases holds great importance to reduce the losses. The advanced enzyme-linked immunosorbent assays (ELISAs for the detection of antigen as well as antibodies directly from the samples and molecular diagnostic assays along with microsatellites comprehensively assist in diagnosis as well as treatment and epidemiological studies. The present review discusses the advancements made in the diagnosis of common infectious respiratory diseases of sheep and goats. It would update the knowledge and help in adapting and implementing appropriate, timely, and confirmatory diagnostic procedures. Moreover, it would assist in designing appropriate prevention protocols and devising suitable control strategies to overcome respiratory diseases and alleviate the economic losses.

    First Nations and Inuit youth who abuse solvents are one of the most highly stigmatized substance-abusing groups in Canada. Drawing on a residential treatment response that is grounded in a culture-based model of resiliency, this article discusses the cultural implications for psychiatry's individualized approach to treating mental disorders. A systematic review of articles published in The Canadian Journal of Psychiatry during the past decade, augmented with a review of Canadian and international literature, revealed a gap in understanding and practice between Western psychiatric disorder-based and Aboriginal culture-based approaches to treatment and healing from substance abuse and mental disorders. Differing conceptualizations of mental health and substance abuse are discussed from Western psychiatric and Aboriginal worldviews, with a focus on connection to self, community, and political context. Applying an Aboriginal method of knowledge translation-storytelling-experiences from front-line workers in a youth solvent abuse treatment centre relay the difficulties with applying Western responses to Aboriginal healing. This lends to a discussion of how psychiatry can capitalize on the growing debate regarding the role of culture in the treatment of Aboriginal youth who abuse solvents. There is significant need for culturally competent psychiatric research specific to diagnosing and treating First Nations and Inuit youth who abuse substances, including solvents. Such understanding for front-line psychiatrists is necessary to improve practice. A health promotion perspective may be a valuable beginning point for attaining this understanding, as it situates psychiatry's approach to treating mental disorders within the etiology for Aboriginal Peoples.

  19. Effectiveness of sound therapy in patients with tinnitus resistant to previous treatments: importance of adjustments

    Flavia Alencar de Barros Suzuki

    Full Text Available ABSTRACT INTRODUCTION: The difficulty in choosing the appropriate therapy for chronic tinnitus relates to the variable impact on the quality of life of affected patients and, thus, requires individualization of treatment. OBJECTIVE: To evaluate the effectiveness of using sound generators with individual adjustments to relieve tinnitus in patients unresponsive to previous treatments. METHODS: A prospective study of 10 patients with chronic tinnitus who were unresponsive to previous drug treatments, five males and five females, with ages ranging from 41 to 78 years. Bilateral sound generators (Reach 62 or Mind 9 models were used daily for at least 6 h during 18 months. The patients were evaluated at the beginning, after 1 month and at each 3 months until 18 months through acuphenometry, minimum masking level, the Tinnitus Handicap Inventory, visual analog scale, and the Hospital Anxiety and Depression Scale. The sound generators were adjusted at each visit. RESULTS: There was a reduction of Tinnitus Handicap Inventory in nine patients using a protocol with a customized approach, independent of psychoacoustic characteristics of tinnitus. The best response to treatment occurred in those with whistle-type tinnitus. A correlation among the adjustments and tinnitus loudness and minimum masking level was found. Only one patient, who had indication of depression by Hospital Anxiety and Depression Scale, did not respond to sound therapy. CONCLUSION: There was improvement in quality of life (Tinnitus Handicap Inventory, with good response to sound therapy using customized settings in patients who did not respond to previous treatments for tinnitus.

  20. Partnering for optimal respiratory home care: physicians working with respiratory therapists to optimally meet respiratory home care needs.

    Spratt, G; Petty, T L

    2001-05-01

    The need for respiratory care services continues to increase, reimbursement for those services has decreased, and cost-containment measures have increased the frequency of home health care. Respiratory therapists are well qualified to provide home respiratory care, reduce misallocation of respiratory services, assess patient respiratory status, identify problems and needs, evaluate the effect of the home setting, educate the patient on proper equipment use, monitor patient response to and complications of therapy, monitor equipment functioning, monitor for appropriate infection control procedures, make recommendations for changes to therapy regimen, and adjust therapy under the direction of the physician. Teamwork benefits all parties and offers cost and time savings, improved data collection and communication, higher job satisfaction, and better patient monitoring, education, and quality of life. Respiratory therapists are positioned to optimize treatment efficacy, maximize patient compliance, and minimize hospitalizations among patients receiving respiratory home care.

  1. [The importance of a well-balanced diet in the comprehensive treatment of cystic fobrosis].

    Brzostek, Karolina; Ukleja, Anna

    2017-01-23

    Cystic fibrosis (CF) is a genetic disease characterized by formation and accumulation of sticky, thick slime in human's organs. It runs to impairment of lungs functioning that results in development of higher risk of malnutrition and chronic food deficiencies. One of the elements of CF's treatment is nutrition therapy including properly composed diet considering accelerated demand for energy, proteins and lipids. The replenishment of nutrition treatment is pancreatic enzymes and fat-soluble vitamins supplementation. In the article, there was analyzed the meaning of nutrition in CF's treatment. It is necessary in maintenance of right nutrition condition that contributes to improvement of lungs functioning, preventing of nutrients' deficiency and raising the quality of life.

  2. Cancer treatment in childhood and testicular function: the importance of the somatic environment

    Stukenborg, Jan-Bernd; Jahnukainen, Kirsi; Hutka, Marsida

    2018-01-01

    Testicular function and future fertility may be affected by cancer treatment during childhood. Whilst survival of the germ (stem) cells is critical for ensuring the potential for fertility in these patients, the somatic cell populations also play a crucial role in providing a suitable environment to support germ cell maintenance and subsequent development. Regulation of the spermatogonial germ-stem cell niche involves many signalling pathways with hormonal influence from the hypothalamo-pituitary-gonadal axis. In this review, we describe the somatic cell populations that comprise the testicular germ-stem cell niche in humans and how they may be affected by cancer treatment during childhood. We also discuss the experimental models that may be utilized to manipulate the somatic environment and report the results of studies that investigate the potential role of somatic cells in the protection of the germ cells in the testis from cancer treatment.

  10. On the importance of prompt oxygen changes for hypofractionated radiation treatments

    Kissick, Michael; Campos, David; Van der Kogel, Albert; Kimple, Randall

    2013-01-01

    This discussion is motivated by observations of prompt oxygen changes occurring prior to a significant number of cancer cells dying (permanently stopping their metabolic activity) from therapeutic agents like large doses of ionizing radiation. Such changes must be from changes in the vasculature that supplies the tissue or from the metabolic changes in the tissue itself. An adapted linear–quadratic treatment is used to estimate the cell survival variation magnitudes from repair and reoxygenation from a two-fraction treatment in which the second fraction would happen prior to significant cell death from the first fraction, in the large fraction limit. It is clear the effects of oxygen changes are likely to be the most significant factor for hypofractionation because of large radiation doses. It is a larger effect than repair. Optimal dose timing should be determined by the peak oxygen timing. A call is made to prioritize near real time measurements of oxygen dynamics in tumors undergoing hypofractionated treatments in order to make these treatments adaptable and patient-specific. (note)

  12. Antibiotic Use in Children with Acute Respiratory or Ear Infections: Prospective Observational Comparison of Anthroposophic and Conventional Treatment under Routine Primary Care Conditions

    Harald J. Hamre

    2014-01-01

    Full Text Available Children with acute respiratory or ear infections (RTI/OM are often unnecessarily prescribed antibiotics. Antibiotic resistance is a major public health problem and antibiotic prescription for RTI/OM should be reduced. Anthroposophic treatment of RTI/OM includes anthroposophic medications, nonmedication therapy and if necessary also antibiotics. This secondary analysis from an observational study comprised 529 children <18 years from Europe (AT, DE, NL, and UK or USA, whose caregivers had chosen to consult physicians offering anthroposophic (A- or conventional (C- treatment for RTI/OM. During the 28-day follow-up antibiotics were prescribed to 5.5% of A-patients and 25.6% of C-patients (P<0.001; unadjusted odds ratio for nonprescription in A- versus C-patients 6.58 (95%-CI 3.45–12.56; after adjustment for demographics and morbidity 6.33 (3.17–12.64. Antibiotic prescription rates in recent observational studies with similar patients in similar settings, ranged from 31.0% to 84.1%. Compared to C-patients, A-patients also had much lower use of analgesics, somewhat quicker symptom resolution, and higher caregiver satisfaction. Adverse drug reactions were infrequent (2.3% in both groups and not serious. Limitation was that results apply to children of caregivers who consult A-physicians. One cannot infer to what extent antibiotics might be avoided in children who usually receive C-treatment, if they were offered A-treatment.

    It had been more than 5 years since the first case of Middle East Respiratory Syndrome coronavirus infection (MERS-CoV) was recorded, but no specific treatment has been investigated in randomized clinical trials. Results from in vitro and animal studies suggest that a combination of lopinavir/ritonavir and interferon-β1b (IFN-β1b) may be effective against MERS-CoV. The aim of this study is to investigate the efficacy of treatment with a combination of lopinavir/ritonavir and recombinant IFN-β1b provided with standard supportive care, compared to treatment with placebo provided with standard supportive care in patients with laboratory-confirmed MERS requiring hospital admission. The protocol is prepared in accordance with the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) guidelines. Hospitalized adult patients with laboratory-confirmed MERS will be enrolled in this recursive, two-stage, group sequential, multicenter, placebo-controlled, double-blind randomized controlled trial. The trial is initially designed to include 2 two-stage components. The first two-stage component is designed to adjust sample size and determine futility stopping, but not efficacy stopping. The second two-stage component is designed to determine efficacy stopping and possibly readjustment of sample size. The primary outcome is 90-day mortality. This will be the first randomized controlled trial of a potential treatment for MERS. The study is sponsored by King Abdullah International Medical Research Center, Riyadh, Saudi Arabia. Enrollment for this study began in November 2016, and has enrolled thirteen patients as of Jan 24-2018. ClinicalTrials.gov, ID: NCT02845843 . Registered on 27 July 2016.

  14. Treatment of primary brain lymphoma without immune deficiency, The importance of chemotherapy before radiotherapy

    Keihani M

    1999-09-01

    Full Text Available The purpose of this study was to find a more efficacious treatment for patients with primary central nervous system Lymphoma using chemotherapy. The objective was to determine the optimal time for radiotherapy treatment in relation to chemotherapy. Retrospective evaluation in patients with brain lymphoma was conducted from 1992 to 1998. Twenty-three patients were evaluated. Patients were divided into two groups based on the timing of radiotherapy in relation to the chemotherapy. The first group of patients (n=13 initially received radiotherapy followed by chemotherapy. Five of these patients receied classic CHOP (cyclophosphamide, Doxorubicine, Vincistine and Prednisone, six patients received Cis-platin (60 Megs/M2 and Etoposide (120 Megs/M2 and two patients received Cis-platin (60 Megs/M2, Etoposide (120 Megs/M2 and Cytarabine (600 Megs/M2 every 2 to 3 weeks. The second group of patients (Group II, n=10 received the followeing treatment regimen: a course of BCNU 120 Megs/M2 with Ifosfamide 1200 Megs/M2, Mesna and Etoposide 120 Megs/M2 on the first day of treatment (course A. Two weeks later, treatment was continued with a course of Cis-platin 35 Megs/M2 and Cytarabine 600 Megs/M2 (course B. The treatment was continued 14 days later with a course of Mitoxantron 12 Megs/M2, Ifosfamide 1200 Megs/M2 puls Mesna (course C. After the fourth week of chemotherapy, these patients received radiotherapy to the brain (5000 RADS in 4 weeks. During radiotherapy and at the beginning of course chemotherapy, intrathecal therapy with Methorexate 12 Megs/M2 and Cytarabine 60 Megs/M2 was given. Immediately after radiotherapy, the same chemothotrexate 12 Megs/M2 and Cytarabine 60 Megs/M2 was given. Immediately after radiotherapy, the same chemotherapy treatment was repeated to a total of 3 times. After complete clearance of the tumor determined by MRI and absence of tumor cells in the spinal fluid, the chemotherapeutic regimen was repeated one last time. The

  17. A randomised controlled trial on the effect of mask choice on residual respiratory events with continuous positive airway pressure treatment.

    Ebben, Matthew R; Narizhnaya, Mariya; Segal, Alan Z; Barone, Daniel; Krieger, Ana C

    2014-06-01

    It has been found that mask style can affect the amount of continuous positive airway pressure (CPAP) required to reduce an apnoea/hyponoea index (AHI) to mask style to another post titration could affect the residual AHI with CPAP. The purpose of this study was to investigate the differences in residual AHI with CPAP treatment between oronasal and nasal masks. Twenty-one subjects (age mean (M)=62.9, body mass index (BMI) M=29.6 kg/m2) were randomised (14 subjects completed the protocol) to undergo an in-laboratory CPAP titration with either a nasal mask or an oronasal mask. Subjects were then assigned this mask for 3weeks of at-home CPAP use with the optimal treatment pressure determined on the laboratory study (CPAP M=8.4 cm of H2O). At the end of this 3-week period, data were collected from the CPAP machine and the subject was given the other mask to use with the same CPAP settings for the next 3weeks at home (if the nasal mask was given initially, the oronasal one was given later and vice versa). On completion of the second 3-week period, data on residual AHI were again collected and compared with the first 3-week period on CPAP. A Wilcoxon Signed-Rank Test (two-tailed) revealed that residual AHI with CPAP treatment was significantly higher with the oronasal compared with the nasal mask (z = -3.296, pmask, and 50% of the subjects had a residual AHI >10/h in the oronasal mask condition, even though all of these subjects were titrated to an AHI of mask compared with a nasal mask. Switching to an oronasal mask post titration results in an increase in residual AHI with CPAP treatment, and pressure adjustment may be warranted. Copyright © 2014 Elsevier B.V. All rights reserved.

    Veldeman, Liv; De Gersem, Werner; Speleers, Bruno; Truyens, Bart; Van Greveling, Annick; Van den Broecke, Rudy; De Neve, Wilfried

    2012-04-01

    The objective of this study was to compare setup precision, respiration-related breast movement and treatment time between prone and supine positions for whole-breast irradiation. Ten patients with early-stage breast carcinoma after breast-conserving surgery were treated with prone and supine whole breast-irradiation in a daily alternating schedule. Setup precision was monitored using cone-beam computed tomography (CBCT) imaging. Respiration-related breast movement in the vertical direction was assessed by magnetic sensors. The time needed for patient setup and for the CBCT procedure, the beam time, and the length of the whole treatment slot were also recorded. Random and systematic errors were not significantly different between positions in individual patients for each of the three axes (left-right, longitudinal, and vertical). Respiration-related movement was smaller in prone position, but about 80% of observations showed amplitudes movement was smaller in prone position. The longer treatment slots in prone position can probably be attributed to the higher repositioning need. Copyright © 2012 Elsevier Inc. All rights reserved.

  20. Primary central nervous system lymphoma: age and performance status are more important than treatment modality

    Corry, June; Smith, Jennifer G.; Wirth, Andrew; Quong, George; Liew, Kuen Hoe

    1998-01-01

    Purpose: To assess prognostic factors and treatment modalities of patients with primary central nervous system lymphoma (PCNSL) in terms of response rates, patterns of failure and overall survival. Methods and Materials: Sixty-two patients presenting with PCNSL between 1982 and 1994 at Peter MacCallum Cancer Institute with no evidence of human immunodeficiency virus infection were included in the study. Their median age was 60 years; World Health Organisation (WHO) performance status was ≥2 in 85%. All patients were planned to receive whole brain irradiation; 7 also received spinal irradiation. The median planned dose to the target volume was 50.4 Gy. Twenty patients were planned to receive chemotherapy as well. Patients were followed up to June 20, 1995, giving a median follow-up for 14 surviving patients of 5.4 years, range 0.3 to 10.2 years. Results: The clinical response rate to treatment was 77% [95% confidence interval (CI) 65 to 87%]. The estimated median overall survival was 20.6 months (CI 12.4 to 33.4 months). On univariate analysis male gender, age <60 years, WHO performance status ≤1, treatment to the target volume ≥45 Gy, and treatment with additional chemotherapy, were associated with a significantly better overall survival (p < 0.05). On multivariate analysis only age and performance status remained significant prognostic variables. Relapse involved the central nervous system or cerebrospinal fluid (CSF) in all patients with known sites of relapse except three who had ocular relapse only. There was a low incidence of relapse in the initial brain site (23% of known cases) and a high incidence (50%) of CSF/spinal cord relapse. Of 48 deaths, 15 were related to initial or subsequent treatment. Conclusions: Patient outcome is strongly influenced by age and performance status. Studies suggesting better survival for patients treated with chemoradiation may reflect patient selection rather than treatment variables. Optimal management remains to be

    Full Text Available In this research we have determined germination energy and germination of seeds of sunflower hybrids ‘Luka’ and ‘Apolon’, at the beginning of storage and 6, 12 and 18 months after of storage period (2011-2012 in the floor concrete storage at two different air temperatures and humidity (S-1: air temperature 15-18°C and relative air humidity 65-70% as well as in climate chamber (S-2: air temperature 10-12°C and relative air humidity 60-65%, stored in four treatments (Control: processed-untreated seed; T-1: treated with A.I. metalaxyl-M; T-2: treated with A.I. metalaxyl-M + A.I. imidacloprid and T-3: treated with A.I. metalaxyl-M + A.I. clothianidin. Based on the obtained results we have determined that sunflower hybrid ‘Luka’, compared to hybrid ‘Apolon’, in the given storage conditions and with the same seed treatment has 5-8% higher germination energy and seed germination and that in climate chamber both hybrids have 5-7% higher germination energy. Seed treatment of both sunflower hybrids with A.I. imidacloprid maximally reduced initial germination energy and seed germination in all tested periods and conditions of storage. On the average, natural seed, after 18 months of storage did not have better seed quality compared to seed treated with A.I. metalaxyl-M while other treatments had more significant influence on reduction of germination energy and seed germination, 6-15%. On the average, compared to other variants, seeds treated with A.I. metalaxyl-M after 18 months of storage in both storage conditions had higher germination energy by 4-15%, and seed germination by 2-12%.

  3. Importance of Electrode Material in the Electrochemical Treatment of Wastewater Containing Organic Pollutants

    Panizza, Marco

    Electrochemical oxidation is a promising method for the treatment of wastewaters containing organic compounds. As a general rule, the electrochemical incineration of organics at a given electrode can take place at satisfactory rates and without electrode deactivation only at high anodic potentials in the region of the water discharge due to the participation of the intermediates of oxygen evolution. The nature of the electrode material strongly influences both the selectivity and the efficiency of the process. In particular, anodes with low oxygen evolution overpotential (i.e., good catalysts for oxygen evolution reactions), such as graphite, IrO2, RuO2, and Pt only permit the partial oxidation of organics, while anodes with high oxygen evolution overpotential (i.e., anodes that are poor catalysts for oxygen evolution reactions), such as SnO2, PbO2, and boron-doped diamond (BDD) favor the complete oxidation of organics to CO2 and so are ideal electrodes for wastewater treatment.However, the application of SnO2 and PbO2 anodes may be limited by their short service life and the risk of lead contamination, while BDD electrodes exhibit good chemical and electrochemical stability, a long life, and a wide potential window for water discharge, and are thus promising anodes for industrial-scale wastewater treatment.

    refractory periods. The same system can be perturbed to a state in which amplitude of oscillation is attenuated or abolished. We have characterized critical perturbations which induce transitions between these two states, giving rise to patterns of dysrhythmic activity that are similar to those seen in the experiments. We illustrate the importance of noise in initiation and termination of rhythm, comparable to normal respiratory rhythm intermixed with spontaneous dysrhythmias. In the BvP system the incidence and duration of dysrhythmia is shown to be strongly influenced by the level of noise. These studies should lead to greater understanding of rhythmicity and integrative responses of the respiratory control system, and provide insight into disturbances in control mechanisms that cause apnea and aspiration in clinical disease states.

  5. Bi-level CPAP does not improve gas exchange when compared with conventional CPAP for the treatment of neonates recovering from respiratory distress syndrome.

    Lampland, Andrea L; Plumm, Brenda; Worwa, Cathy; Meyers, Patricia; Mammel, Mark C

    2015-01-01

    We hypothesised that short-term application of bi-level nasal continuous positive airway pressure CPAP (SiPAP) compared with conventional nasal CPAP (nCPAP) at the same mean airway pressure in infants with persistent oxygen need recovering from respiratory distress syndrome would improve CO2 removal with no change in oxygen requirement. Non-blinded, randomised, observational four-period crossover study. Level III NICU; low-birthweight infants requiring CPAP and oxygen while recovering from respiratory distress syndrome. Infants requiring nasal CPAP for >24 h prior to study enrolment, and fraction of inspired oxygen requirement (FiO2) of 0.25-0.5, were randomised to either nCPAP or SiPAP. A crossover design with four 1 h treatment periods was used such that each infant received both treatments twice. Oxygen saturations (SaO2), transcutaneous CO2 (tcCO2) and vital signs were monitored continuously. Polysomnographic recordings were analysed for apnoea, bradycardia and oxygen desaturation. Twenty low-birthweight infants receiving 0.3±0.04% supplemental oxygen on CPAP of 6 cm H2O were studied at an average of 33 days of age (±23 days, SD). There were no differences in tcCO2 or other physiological parameters except mean blood pressure, which was lower during nCPAP (52.3±8.3 vs 54.4±9.1 mm Hg; ±SD; p<0.01). No differences in short or prolonged apnoea, bradycardia or significant desaturation events were observed. At similar mean airway pressures, SiPAP does not improve CO2 removal, oxygenation or other studied physiological parameters with the exception of mean blood pressure, which was not clinically significant.

  7. Paracrine effects and heterogeneity of marrow-derived stem/progenitor cells: relevance for the treatment of respiratory diseases.

    Conese, Massimo; Carbone, Annalucia; Castellani, Stefano; Di Gioia, Sante

    2013-01-01

    Stem cell-based treatment may represent a hope for the treatment of acute lung injury and pulmonary fibrosis, and other chronic lung diseases, such as cystic fibrosis, asthma and chronic obstructive pulmonary disease (COPD). It is well established in preclinical models that bone marrow-derived stem and progenitor cells exert beneficial effects on inflammation, immune responses and repairing of damage in virtually all lung-borne diseases. While it was initially thought that the positive outcome was due to a direct engraftment of these cells into the lung as endothelial and epithelial cells, paracrine factors are now considered the main mechanism through which stem and progenitor cells exert their therapeutic effect. This knowledge has led to the clinical use of marrow cells in pulmonary hypertension with endothelial progenitor cells (EPCs) and in COPD with mesenchymal stromal (stem) cells (MSCs). Bone marrow-derived stem cells, including hematopoietic stem/progenitor cells, MSCs, EPCs and fibrocytes, encompass a wide array of cell subsets with different capacities of engraftment and injured tissue-regenerating potential. The characterization/isolation of the stem cell subpopulations represents a major challenge to improve the efficacy of transplantation protocols used in regenerative medicine and applied to lung disorders.

    The effectiveness of antenatal corticosteroid therapy for foetal lung maturation in pre-term infants is well known, but there is uncertainty about the time that the treatment remains effective. A descriptive, longitudinal study was conducted to determine whether the need for surfactant administration was determined by the time-lapse between corticosteroids administration and delivery, and when repeating the doses of maternal corticosteroids should be considered. A total of 91 premature infants ≤32 weeks and/or ≤1,500 g (limit 34+6 weeks) whose mothers had received a complete course of corticosteroids were included. In patients at 27-34+6 weeks, we found that the longer the time elapsed between delivery and administration of corticosteroids, most likely were the babies to require treatment with surfactant (P=.027). The resulting ROC curve determined an 8-days cut-off after which repeating a dose of corticosteroids should be assessed. Copyright © 2013 Asociación Española de Pediatría.

  11. Comparison of rSP-C surfactant with natural and synthetic surfactants after late treatment in a rat model of the acute respiratory distress syndrome

    Häfner, Dietrich; Germann, Paul-Georg; Hauschke, Dieter

    1998-01-01

    In a previous paper we showed that an SP-C containing surfactant preparation has similar activity as bovine-derived surfactants in a rat lung lavage model of the adult respiratory distress syndrome. In this study surfactant was given ten minutes after the last lavage (early treatment). In the present investigation we were interested how different surfactant preparations behave when they are administered 1 h after the last lavage (late treatment). Four protein containing surfactants (rSP-C surfactant, bLES, Infasurf and Survanta) were compared with three protein-free surfactants (ALEC, Exosurf and the phospholipid (PL) mixture of the rSP-C surfactant termed PL surfactant) with respect to their ability to improve gas exchange in this more stringent model when surfactant is given one hour after the last lavage. For better comparison of the surfactants the doses were related to phospholipids. The surfactants were given at doses of 25, 50 and 100 mg kg−1 body weight. The surfactants were compared to an untreated control group that was only ventilated for the whole experimental period. Tracheotomized rats (8–12 per dose and surfactant) were pressure-controlled ventilated (Siemens Servo Ventilator 900C) with 100% oxygen at a respiratory rate of 30 breaths min−1, inspiration expiration ratio of 1 : 2, peak inspiratory pressure of 28 cmH2O at positive endexpiratory pressure (PEEP) of 8 cmH2O. Animals were ventilated for one hour after the last lavage and thereafter the surfactants were intratracheally instilled. During the whole experimental period the ventilation was not changed. Partial arterial oxygen pressures (PaO2, mmHg) at 30 min and 120 min after treatment were used for statistical comparison. All protein containing surfactants caused a dose-dependent increase of the reduced PaO2 values at 30 min after treatment. The protein-free surfactants showed only weak dose-dependent increase in PaO2 values at this time. This difference between the

    Seventy-six, crossbred, porcine reproductive and respiratory syndrome virus (PRRSV)-free pigs were weaned at 12 days of age and randomly assigned to seven groups of 10 to 11 pigs each. Pigs in group 1 served as unchallenged controls. Pigs in groups 2 to 7 were challenged intranasally with 2 ml of high-virulence PRRSV isolate VR-2385 (104.47 50% tissue culture infective doses per 2 ml) on day 0 of the study (30 days of age). Seven days after PRRSV challenge, pigs in groups 2 to 7 were challenged intranasally with 2 ml of Streptococcus suis serotype 2 (108.30 CFU/2 ml). Group 2 pigs served as untreated positive controls. Antimicrobial treatments included daily intramuscular injection with 66,000 IU of procaine penicillin G per kg of body weight on days 8 to 10 (group 3), drinking water medication with 23.1 mg of tiamulin per kg during days 8 to 10 (group 4), and daily intramuscular injection of 5.0 mg of ceftiofur hydrochloride per kg on days 8 to 10 (group 5). Vaccination regimens included two intramuscular doses of an autogenous killed S. suis vaccine (group 6) prior to S. suis challenge or a single 2-ml intramuscular dose of an attenuated live PRRSV vaccine (group 7) 2 weeks prior to PRRSV challenge. Mortality was 0, 63, 45, 54, 9, 40, and 81% in groups 1 to 7, respectively. Ceftiofur treatment was the only regimen that significantly (P < 0.05) reduced mortality associated with PRRSV and S. suis coinfection. The other treatments and vaccinations were less effective. We conclude that ceftiofur administered by injection for three consecutive days following S. suis challenge was the most effective regimen for minimizing disease associated with PRRSV and S. suis coinfection.

  14. Energy benchmarking in wastewater treatment plants: the importance of site operation and layout.

    Belloir, C; Stanford, C; Soares, A

    2015-01-01

    Energy benchmarking is a powerful tool in the optimization of wastewater treatment plants (WWTPs) in helping to reduce costs and greenhouse gas emissions. Traditionally, energy benchmarking methods focused solely on reporting electricity consumption, however, recent developments in this area have led to the inclusion of other types of energy, including electrical, manual, chemical and mechanical consumptions that can be expressed in kWh/m3. In this study, two full-scale WWTPs were benchmarked, both incorporated preliminary, secondary (oxidation ditch) and tertiary treatment processes, Site 1 also had an additional primary treatment step. The results indicated that Site 1 required 2.32 kWh/m3 against 0.98 kWh/m3 for Site 2. Aeration presented the highest energy consumption for both sites with 2.08 kWh/m3 required for Site 1 and 0.91 kWh/m3 in Site 2. The mechanical energy represented the second biggest consumption for Site 1 (9%, 0.212 kWh/m3) and chemical input was significant in Site 2 (4.1%, 0.026 kWh/m3). The analysis of the results indicated that Site 2 could be optimized by constructing a primary settling tank that would reduce the biochemical oxygen demand, total suspended solids and NH4 loads to the oxidation ditch by 55%, 75% and 12%, respectively, and at the same time reduce the aeration requirements by 49%. This study demonstrated that the effectiveness of the energy benchmarking exercise in identifying the highest energy-consuming assets, nevertheless it points out the need to develop a holistic overview of the WWTP and the need to include parameters such as effluent quality, site operation and plant layout to allow adequate benchmarking.

    2013-01-01

    Full Text Available Rhinolithiasis is a rare condition involving a mineralized mass located in the nasal cavity. It may be endogenous or exogenous in origin. The fact that it appears with different symptoms can make diagnosis difficult. Rhinolithiasis was diagnosed as a result of endoscopic examination in two patients previously diagnosed with sinusitis and with no lessening of symptoms despite numerous applications of medical treatment. Rhinolithiasis should be considered in long-term fetid nasal discharges and unilateral nasal obstructions, and the patient should be referred to an ear, nose and throat specialist for endoscopic examination.

    Olfactory neuroblastoma (ONB) is a rare entity that constitutes less than 5% of nasosinusal malignancies. Mainstream treatment consists in surgical resection+/-adjuvant radiotherapy. By exposing results observed with apparition of new therapeutic options as neoadjuvant chemotherapy, the objective is to evaluate a series and a review of the current literature. A retrospective review was conducted including patients diagnosed and followed-up for ONB from 2008 to 2015 in our institution. 9 patients were included. Mean follow-up of 52.5 months (range 10-107). Kadish stage: A, 1 patient (11.1%) treated with endoscopic surgery; B, 2 patients (22.2%) treated with endoscopic surgery (one of them received adjuvant radiotherapy); C, 6 patients (66.7%), 4 patients presented intracranial extension and were treated with neoadjuvant chemotherapy followed by surgery and radiotherapy. The other 2 patients presented isolated orbital extension, treated with radical surgery (endoscopic or craniofacial resection) plus radiotherapy. The 5-year disease free and overall survival observed was 88.9%. Neoadjuvant chemotherapy could be an effective treatment for tumor reduction, improving surgical resection and reducing its complications.

    Full Text Available Pandemic influenza caused significant increases in healthcare utilization across several continents including the use of high-intensity rescue therapies like extracorporeal membrane oxygenation (ECMO or high-frequency oscillatory ventilation (HFOV. The severity of illness observed with pandemic influenza in 2009 strained healthcare resources. Because lung injury in ARDS can be influenced by daily management and multiple organ failure, we performed a retrospective cohort study to understand the severity of H1N1 associated ARDS after adjustment for treatment. Sixty subjects were identified in our hospital with ARDS from "direct injury" within 24 hours of ICU admission over a three month period. Twenty-three subjects (38.3% were positive for H1N1 within 72 hours of hospitalization. These cases of H1N1-associated ARDS were compared to non-H1N1 associated ARDS patients. Subjects with H1N1-associated ARDS were younger and more likely to have a higher body mass index (BMI, present more rapidly and have worse oxygenation. Severity of illness (SOFA score was directly related to worse oxygenation. Management was similar between the two groups on the day of admission and subsequent five days with respect to tidal volumes used, fluid balance and transfusion practices. There was, however, more frequent use of "rescue" therapy like prone ventilation, HFOV or ECMO in H1N1 patients. First morning set tidal volumes and BMI were significantly associated with increased severity of lung injury (Lung injury score, LIS at presentation and over time while prior prescription of statins was protective. After assessment of the effect of these co-interventions LIS was significantly higher in H1N1 patients. Patients with pandemic influenza-associated ARDS had higher LIS both at presentation and over the course of the first six days of treatment when compared to non-H1N1 associated ARDS controls. The difference in LIS persisted over the duration of observation in patients

    This study aims to evaluate 3D dosimetric impact for MIP image and each phase image in stereotactic body radiotherapy (SBRT) for lung cancer using volumetric modulated arc therapy (VMAT). For each of 5 patients with non-small-cell pulmonary tumors, a respiration-correlated four dimensional computed tomography (4DCT) study was performed . We obtain ten 3D CT images corresponding to phases of a breathing cycle. Treatment plans were generated using MIP CT image and each phases 3D CT. We performed the dose verification of the TPS with use of the Ion chamber and COMPASS. The dose distribution that were 3D reconstructed using MIP CT image compared with dose distribution on the corresponding phase of the 4D CT data. Gamma evaluation was performed to evaluate the accuracy of dose delivery for MIP CT data and 4D CT data of 5 patients. The average percentage of points passing the gamma criteria of 2 mm/2% about 99%. The average Homogeneity Index difference between MIP and each 3D data of patient dose was 0.03∼0.04. The average difference between PTV maximum dose was 3.30 cGy, The average different Spinal Coad dose was 3.30 cGy, The average of difference with V{sub 20}, V{sub 10}, V{sub 5} of Lung was -0.04%∼2.32%. The average Homogeneity Index difference between MIP and each phase 3D data of all patient was -0.03∼0.03. The average PTV maximum dose difference was minimum for 10% phase and maximum for 70% phase. The average Spain cord maximum dose difference was minimum for 0% phase and maximum for 50% phase. The average difference of V{sub 20}, V{sub 10}, V{sub 5} of Lung show bo certain trend. There is no tendency of dose difference between MIP with 3D CT data of each phase. But there are appreciable difference for specific phase. It is need to study about patient group which has similar tumor location and breathing motion. Then we compare with dose distribution for each phase 3D image data or MIP image data. we will determine appropriate image data for treatment plan.

Extraction of soluble coke with n-hexane and/or leaching of foulant elements with oxalic acid were performed before burning insoluble coke under air. Oxidized catalysts were leached with 9 mol L-1 sulfuric acid. Iron was the only foulant element partially leached by oxalic acid. The amount of insoluble matter in sulfuric acid was drastically reduced when iron and/or soluble coke were previously removed. Losses of active phase metals (Ni, Mo during leaching with oxalic acid were compensated by the increase of their recovery in the sulfuric acid leachate.

  3. The importance of the descending monoamine system for the pain experience and its treatment

    Dickenson, Anthony H

    2009-01-01

    Brainstem and midbrain areas engage descending facilitatory and inhibitory neurones to potentiate or suppress the passage of sensory inputs from spinal loci to the brain. The balance between descending controls, both excitatory and inhibitory, can be altered in various pain states and can critically determine the efficacy of certain analgesic drugs. There is good evidence for a prominent α2 adrenoceptor-mediated inhibitory system and for 5-HT3 receptor-mediated excitatory control of spinal cord activity that originates in supraspinal areas. Given the multiple roles of these transmitters in pain and functions such as sleep, depression, and anxiety, the link between spinal and supraspinal processing of noxious inputs (via the monoamine transmitters) could be pivotal for linking the sensory and affective components of pain and their common co-morbidities, and also may potentially explain differences in pain scores and treatment outcomes in the patient population.

  4. Transacting generation attributes across market boundaries: Compatible information systems and the treatment of imports and exports

    Grace, Robert; Wiser, Ryan

    2002-11-01

    Voluntary markets for ''green'' power, and mandatory policies such as fuel source disclosure requirements and renewables portfolio standards, each rely on the ability to differentiate electricity by the ''attributes'' of the generation. Throughout North America, electricity markets are devising accounting and verification systems for generation ''attributes'': those characteristics of a power plant's production such as fuel source and emissions that differentiate it from undifferentiated (or ''commodity'') electricity. These accounting and verification systems are intended to verify compliance with market mandates, create accurate disclosure labels, substantiate green power claims, and support emissions markets. Simultaneously, interest is growing in transacting (importing or exporting) generation attributes across electricity market borders, with or without associated electricity. Cross-border renewable attribute transactions have advantages and disadvantages. Broad access to markets may encourage more renewable generation at lower cost, but this result may conflict with desires to assure that at least some renewable resources are built locally to achieve either local policy goals or purchaser objectives. This report is intended to serve as a resource document for those interested in and struggling with cross-border renewable attribute transactions. The report assesses the circumstances under which renewable generation attributes from a ''source'' region might be recognized in a ''sink'' region. The report identifies several distinct approaches that might be used to account for and verify attribute import and export transactions, and assesses the suitability of these alternative approaches. Because policymakers have often made systems ''compatibility'' between market areas a pre-requisite to allowing cross

    The interplay between luminal microbes and innate immunity during colonic epithelial repair has been well noted. At the same time, antibiotic has widely been used during flare-ups of ulcerative colitis. The possible effects of luminal microbiota disruption caused by antibiotics usage on epithelial repairing have been scarcely discussed. Innate lymphoid cells (ILCs) embedded in the lamina propria can be modulated by gut microbes, resulting in altered colonic IL-22/pSTAT3 levels, which is considered a prominent molecular axis in tissue repairing after epithelium damage. This study aimed to investigate whether antibiotics could interfere with ILCs-dependent tissue repair. Dextran sodium sulfate (DSS)-induced colitis was established in mice pre-treated with reagent of different antibiotic spectrum. Both morphological and molecular markers of tissue repair after DSS cessation were detected. ILCs population and function status were also recorded. Further attention was paid to the response of dendritic cells after antibiotics treatment, which were claimed to regulate colonic ILC3s in an IL-23 dependent way. Using of vancomycin resulted in delayed tissue repairing after experimental colitis. Both colonic IL-22/pSTAT3 axis and ILC3 population were found decreased in this situation. Vancomycin treatment diminished the upstream IL-23 and producer dendritic cell population. The reduced dendritic cell number may due to inadequate chemokines and colony-stimulating factors supply. Presence of vancomycin-sensitive microbiota is required for the maturation of ILC3-activating dendritic cells hence maintain the sufficient IL-22/pSTAT3 level in the colon during tissue healing. Manipulation of colonic microbiota may help achieve colonic mucosal healing post inflammation and injury. Copyright © 2016. Published by Elsevier Inc.

    2016-01-01

    Full Text Available Delirium is connected to bad short-term (the increase in hospital mortality rate and hospital days and long-term outcomes (disfunctionality, institutionalisation, cognitive damage and post hospital-release dementia. The objective of this study is to determine whether there are possible incompatibilities of treatment of delirium with the recommendations in the guides of good clinical practice from developed countries. The grounded method was used in the study. The so called principal sampling of 17 psychiatrists, anesthesiologists and registered nurses was conducted. Afterwards, the unstructured interviews with the selectees were conducted, transcribed and analyzed immediately through coding, category and concept detection. Having completed this, the theoretical sampling of new interview examinees was conducted. Their analysis enabled the concepts to be linked into a working theory and graphically displayed. The new sampling, the new interviews and their analysis were then continued interactively until the saturation of the working theory was achieved and the final version of the theory was formulated based on the findings reached through the interviews. Having completed the principal sampling and coding of the transcripts led the researches to the saturation of the theory through the separation of eight categories: A - Delirium as a sign of system infection, B - Therapy - Anaesthesiologists administer benzodiazepines, whereas psychiatrists administer antipsychotics, C - An inconspicuous onset of delirium is overlooked, D - Bleeding as the cause of delirium, E -Anticholinergics as a cause of delirium, F - Misunderstanding the nature of delirium by anaesthesiologists, G -Being aware that the patient is vitally endangered, and H - The nurses apply enhanced health care measures. Delirium is a syndrome which can be prevented in 30 -40% of cases (50. An etiological treatment would help avoid complicating delirium's clinical picture and would very much

    Ignatenco, Sergiu

    2011-01-01

    A patient of 53 years presented fever, swelling and erythema in the perineal region. After computed tomography (CT) was diagnosed Fournier gangrene. After aggressive surgical debridement postoperative evolution was unfavorable. Repeated CT scan trace spread of infection to new areas that led to new surgical debridement on time. Use of CT scan in the postoperative period allows assessment of the effectiveness of surgical debridement and spread of infection. This article presents CT scan images and the most important periods of intraoperative surgical intervention. (authors)

  12. Importance of thymus and its humoral factors in radiation syndrome treatment

    Vavrova, J.

    1983-01-01

    The high radiosensitivity is emphasised of lymphoid tissues and of the immunological response of the organism. The red--uced immunity of the irradiated organism even after sublethal doses lasts for a number of months. The thymus is not only an important lymphoid organ but it also secerns hormones having lymph-stimulating effects. The shielding of the thymus during irradiation or the application of thymosine favourably affected in gamma or X-ray irradiated mice not only the regeneration of damaged lymphoid tissues and of immunological response but also the regeneration of blood formation.

    Full Text Available Chronic lung diseases, such as cystic fibrosis (CF, asthma, and chronic obstructive pulmonary disease (COPD are incurable and represent a very high social burden. Stem cell-based treatment may represent a hope for the cure of these diseases. In this paper, we revise the overall knowledge about the plasticity and engraftment of exogenous marrow-derived stem cells into the lung, as well as their usefulness in lung repair and therapy of chronic lung diseases. The lung is easily accessible and the pathophysiology of these diseases is characterized by injury, inflammation, and eventually by remodeling of the airways. Bone marrow-derived stem cells, including hematopoietic stem/progenitor cells (HSPCs and mesenchymal stromal (stem cells (MSCs, encompass a wide array of cell subsets with different capacities of engraftment and injured tissue regenerating potential. Proof-of-principle that marrow cells administered locally may engraft and give rise to specialized epithelial cells has been given, but the efficiency of this conversion is too limited to give a therapeutic effect. Besides the identification of plasticity mechanisms, the characterization/isolation of the stem cell subpopulations represents a major challenge to improving the efficacy of transplantation protocols used in regenerative medicine for lung diseases.

    Abstract Background New approaches are being sought to safely reduce community antibiotic prescribing. A recent study demonstrated that CRP testing resulted in decreased antibiotic prescribing for lower respiratory tract infection in primary care. There is little other published primary care data available evaluating CRP in the treatment of lower respiratory tract infections in routine clinical practice. This pilot study aims to describe the performance of near-patient CRP testing, in a mixed payments health system. Specific areas to be reviewed included the integrity of the study protocol, testing of data collection forma and acceptability of the intervention. Patients Patients over the age of 18 years, with acute cough and\\/or sore throat with a duration of one month or less, in routine clinical practice. Method Design: A pilot with a cross-sectional design. The first 60 recruited patients were treated with routine clinical management, and GP\\'s had no access to a CRP test. For the subsequent 60 patients, access to CRP testing was available. Participants: 3 GP\\'s in one Irish primary care practice recruited 120 patients, fulfilling the above criteria over five months, from January 1 to May 31, 2010. Main outcome measures: The primary outcome was antibiotic prescription at the index consultation. Secondary outcomes were the numbers of delayed prescriptions issued, patient satisfaction immediately after consultation and re-consultations and antibiotic prescriptions during 28 days follow-up. Results The protocol and data collection forms worked well and the intervention of CRP testing appeared acceptable. Thirty-five (58%) patients in the no-test group received antibiotic prescriptions compared to 27 (45%) in the test group. Both groups demonstrated similarly high level of patient satisfaction (85%). Fourteen (23%) patients in the CRP test group re-attended within 28 days compared to 9 (15%) in the no-CRP test group. Conclusion This pilot study confirms the

  17. Neglected evidence in idiopathic pulmonary fibrosis and the importance of early diagnosis and treatment.

    Cottin, Vincent; Richeldi, Luca

    2014-03-01

    In idiopathic pulmonary fibrosis (IPF), some facts or concepts based on substantial evidence, whilst implicit for learned subspecialists, have previously been neglected and/or not explicitly formulated or made accessible to a wider audience. IPF is strongly associated with cigarette smoking and is predominantly a disease of ageing. However, its cause(s) remain elusive and, thus, it is one of the most challenging diseases for the development of novel effective and safe therapies. With the approval of pirfenidone for patients with mild-to-moderate IPF, an earlier diagnosis of IPF is a prerequisite for earlier treatment and, potentially, improvement of the long-term clinical outcome of this progressive and ultimately fatal disease. An earlier diagnosis may be achieved in IPF by promoting thin-slice chest high-resolution computed tomography screening of interstitial lung disease as a "by-product" of large-scale lung cancer screening strategies in smokers, but other techniques, which have been neglected in the past, are now available. Lung auscultation and early identification of "velcro" crackles has been proposed as a key component of early diagnosis of IPF. An ongoing study is exploring correlations between lung sounds on auscultation obtained using electronic stethoscopes and high-resolution computed tomography patterns.

    The term "management" is best characterized as "managing" economic or social processes to achieve objectives through a rational use of material and immaterial resources by applying the principles, functions, and management methods. This study has been aimed at evaluating the value of an integrated quality management system implemented at the Institute of Cardiovascular Diseases of Vojvodina to improve the quality of treatment. In the period from 2008 to 2010 about 40 employees from the Institute of Cardiovascular Diseases of Vojvodina attended various courses given by the lecturers of the Faculty of Technical Sciences, where the function and significance of the "International Standards Organization" were explained, after which standards of interest were implemented at the Institute of Cardiovascular Diseases of Vojvodina. The Department of Cardiology has introduced 11 cardiac procedures with 5 special instructions, 14 general procedures, and 7 specific procedures with 2 instructions. The Department of Cardiac Surgery has introduced 7 procedures to be implemented. The "Vojvodina score" model was put into practice for the perioperative evaluation of cardiac surgery risk. During 2014, the Institute of Cardiovascular Diseases ofVojvodina obtained accreditation for the period of 7 years. The integrated quality management system must be applied in order to achieve a high level of health care in the shortest possible time and with the least possible consumption of material and human resources. The application of this system in practice gives a realistic insight into the working processes and facilitates their functioning. It demands and requires constant monitoring of the system efficiency along with continuous changes and improvements of all elements of the working processes and functional units.

    PurposeWhile today mechanical thrombectomy is an established treatment option for main branch occlusions in anterior circulation stroke, there is still an ongoing debate on the kind of anesthesia to be preferred. Introducing a simple method for head stabilization, we analyzed safety and duration of endovascular recanalization procedures under general anesthesia (GA) and conscious sedation (CS).MethodsWe retrospectively identified 84 consecutive patients who underwent mechanical thrombectomy owing to acute anterior circulation stroke. Fifty-three were treated under GA and 31 under CS equipped with a standard cervical collar to reduce head movement. We evaluated recanalization results, in-house time to start recanalization, procedure times, technical and clinical complication rates, and conversion rates from CS to GA.ResultsRecanalization of mTICI ≥2b was achieved in 80 % under CS and in 81 % under GA. Median in-house time to start recanalization for CS was 60 min (IQR 28; 44–72) and 77 min (IQR 23; 68–91) for GA (P = 0.001). Median procedure time under CS was 35 min (IQR 43; 69–25) and 41 min (IQR 43; 66–23) for GA (P = 0.9). No major complications such as ICH occurred in either group, and no conversions from CS to GA were necessary.ConclusionMechanical thrombectomy can be performed faster and safely under CS in combination with simple head immobilization using a standard cervical collar.

  2. Acute fluid ingestion in the treatment of orthostatic intolerance - important implications for daily practice.

    2010-11-01

    Rapid water ingestion improves orthostatic intolerance (OI) in multiple system atrophy (MSA) and postural tachycardia syndrome (PoTS). We compared haemodynamic changes after water and clear soup intake, the latter being a common treatment strategy for OI in daily practice. Seven MSA and seven PoTS patients underwent head-up tilt (HUT) without fluid intake and 30 min after drinking 450 ml of water and clear soup, respectively. All patients suffered from moderate to severe OI because of neurogenic orthostatic hypotension (OH) and excessive orthostatic heart rate (HR) increase, respectively. Beat-to-beat cardiovascular indices were measured non-invasively. In MSA, HUT had to be terminated prematurely in 2/7 patients after water, but in 6/7 after clear soup. At 3 min of HUT, there was an increase in blood pressure of 15.7(8.2)/8.3(2.3) mmHg after water, but a decrease of 11.6(18.9)/8.1(9.2) mmHg after clear soup (P clear soup. The attenuation of excessive orthostatic HR increase did not differ significantly after water and clear soup drinking. In MSA, clear soup cannot substitute water for eliciting a pressor effect, but even worsens OI after rapid ingestion. In PoTS, acute water and clear soup intake both result in improvement of OI. These findings cannot solely be explained by difference in osmolarity but may reflect some degree of superimposed postprandial hypotension in widespread autonomic failure in MSA compared to the mild and limited autonomic dysfunction in PoTS. © 2010 The Author(s).

In this study, the importance of N-methyl-D-aspartate (NMDA receptors for the growth and survival of pancreatic cancer was investigated. Immunohistochemistry performed with antibodies against GluN1 and GluN2B revealed that all invasive adenocarcinoma and neuroendocrine pancreatic tumors likely express these two NMDA receptor proteins. These proteins were found to be membrane components of pancreatic cancer cell lines, and both channel-blocker antagonist and GluN2B antagonist significantly reduced cell viability in vitro. Both types of antagonists caused an internalization of the receptors. Dizocilpine maleate (MK-801 and ifenprodil hemitartrate both significantly inhibited the growth of pancreatic tumor xenografts in nu/nu mice. These findings predict that, as for other solid tumors investigated by us, pancreatic cancer could be successfully treated, alone or in combination, with NMDA receptor antagonists or other receptor-inhibiting blocking agents.

  4. Post-treatment haemolysis in severe imported malaria after intravenous artesunate: case report of three patients with hyperparasitaemia

    Rolling Thierry

    2012-05-01

    Full Text Available Abstract Parenteral artesunate has been shown to be a superior treatment option compared to parenteral quinine in adults and children with severe malaria. Little evidence, however, is available on long-term safety. Recently, cases of late-onset haemolysis after parenteral treatment with artesunate have been reported in European travellers with imported Plasmodium falciparum malaria. Therefore, an extended follow-up of adult patients treated for severe imported malaria was started in August 2011 at the University Medical Center Hamburg-Eppendorf. Until January 2012, three patients with hyperparasitaemia (range: 14-21% were included for analysis. In all three patients, delayed haemolysis was detected in the second week after the first dose of intravenous artesunate. Reticulocyte production index remained inadequately low in the 7 – 14 days following the first dose of artesunate despite rapid parasite clearance. Post-treatment haemolysis after parenteral artesunate may be of clinical relevance in particular in imported severe malaria characterized by high parasite levels. Extended follow-up of at least 30 days including controls of haematological parameters after artesunate treatment seems to be indicated. Further investigations are needed to assess frequency and pathophysiological background of this complication.

  5. Perceived autonomy and self-esteem in Dutch dialysis patients: the importance of illness and treatment perceptions.

    2010-07-01

    Compared to healthy people, end-stage renal disease (ESRD) patients participate less in paid jobs and social activities. This study explored the perceived autonomy, state self-esteem and labour participation in ESRD patients on dialysis, and the role illness and treatment perceptions play in these concepts. Patients completed questionnaires at home or in the dialysis centre (N = 166). Data were analysed using bivariate and multivariate analyses. Labour participation among dialysis patients was low, the average autonomy levels were only moderate, and the average self-esteem level was rather high. On the whole, positive illness and treatment perceptions were associated with higher autonomy and self-esteem, but not with labour participation. Multiple regression analyses demonstrated that illness and treatment perceptions explained 18 to 27% of the variance in autonomy and self-esteem. Perceptions of personal control, less impact of the illness and treatment, and less concern were important predictors. Our results indicate that dialysis patients' beliefs about their illness and treatment play an important role in their perceived autonomy and self-esteem. Stimulating positive (realistic) beliefs and altering maladaptive beliefs might contribute to a greater sense of autonomy and self-esteem, and to social participation in general. Interventions focusing on these beliefs may assist patients to adjust to ESRD.

    , 240 and 300 minutes after treatment. The study continued for 5 hours. Results: Surfactant treatment led to a significant improvement in oxygenation within 30 minutes, with the Synsurf group and the Curosurf® group having significantly higher ratios between arterial partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2; P = 0.021 compared to that of the control (saline-treated animals. Dynamic compliance improved in the three groups over time, with no intergroup differences. All of the surfactant-treated animals survived, and one in the saline group died before the study ended. Histology between groups was not different, showing mild–moderate injury patterns. Discussion: Treatment with surfactants before first breath clearly resulted in improved systemic oxygenation within 30 minutes of instillation. Both Synsurf- and Curosurf®-treated animals experienced similar and more sustained improvement in oxygenation and decreased calculated shunt compared to saline-treated animals.

    Full Text Available Objective: We aimed to evaluate the recognition level of bladder cancer in the society by conducting a survey with regards to social awareness in early diagnosis of bladder cancer in this study. Materials and Methods: The survey was conducted on 100 randomly selected patients who were admitted to our clinic in May 2016 for any complaints. In the survey, the main focus was hematuria which is the first and the most common symptom of bladder cancer and questions and statements on this subject was used. Results: Of 100 patients, 67 (66.7% were male, and 33 (33.3% were female. Thirty six of the patients were younger than 50 (36%, and 64 of them (64% were 50 years and older. Education level of 40 (40% patients was found to be university level, and 60 (60% patients we high school graduates or lower. Twenty seven (27% patients had complains about blood in the urine, while 67 (67% of them had no such complaint. Of 27 patients that had complaint about hematuria, which is the most important symptom of bladder cancer 22 (81% were male and 5 (19% were female. We divided the patients into two groups based on 50 age limit. Group 1 included patients who were below 50, while the group 2 consisted of patients who were 50 years old and above. The rates of immediate consultation were determined to be significantly higher in group 2 than group 1. The rate of consulting urology department in the presence of hematuria, and the rates of considering the risk of bladder cancer as a possible diagnosis were higher in group 2, but the difference was not statistically significant. There was no significant difference found between the two groups who were separated by age in terms of required diagnostic tests. The patients were divided into two more groups based on their education level. Group 3 included patients of university graduates, and group 4 included patients with high school graduates or lower. The rates of immediate consultation were significantly higher in group 4

    Full Text Available Presents a review of publications on the problem of combined respiratory infections among children. Viral-bacterial associations are registered  in a group of often ill children in 51.7%. More than half of the patients have herpesvirus infection in various combinations. The presence of a combined acute respiratory viral infection among children in the group from 2 to 6 years was noted in 44.2% of cases, among which, in addition to influenza viruses, RS-, adeno-, etc., metapneumovirus and bocavirus plays an important role.The increase in severity of acute respiratory viral infection with combined  infection, with chlamydia  and mycoplasma infection is shown. A longer and more severe course of whooping cough was observed when combined with respiratory viruses.The revealed facts of frequency of distribution of combined  respiratory infections in children, the severity and duration of their course with the development of various complications and the formation of chronic pathology dictate the need to improve diagnosis and treatment tactics of these forms of infections.

    2012-01-01

    Full Text Available This paper, based on relevant literature articles and the authors' clinical experience, presents a goal-oriented respiratory management for critically ill patients with acute respiratory distress syndrome (ARDS that can help improve clinicians' ability to care for these patients. Early recognition of ARDS modified risk factors and avoidance of aggravating factors during hospital stay such as nonprotective mechanical ventilation, multiple blood products transfusions, positive fluid balance, ventilator-associated pneumonia, and gastric aspiration can help decrease its incidence. An early extensive clinical, laboratory, and imaging evaluation of “at risk patients” allows a correct diagnosis of ARDS, assessment of comorbidities, and calculation of prognostic indices, so that a careful treatment can be planned. Rapid administration of antibiotics and resuscitative measures in case of sepsis and septic shock associated with protective ventilatory strategies and early short-term paralysis associated with differential ventilatory techniques (recruitment maneuvers with adequate positive end-expiratory pressure titration, prone position, and new extracorporeal membrane oxygenation techniques in severe ARDS can help improve its prognosis. Revaluation of ARDS patients on the third day of evolution (Sequential Organ Failure Assessment (SOFA, biomarkers and response to infection therapy allows changes in the initial treatment plans and can help decrease ARDS mortality.

    Changes in physical properties of polymeric materials can be evaluated from their microstructures, which can be investigated using solution carbon-13 nuclear magnetic resonance (NMR). In this type of study spectral resolution is very important, which obviously depend on the sample and solvent. A pre physical treatment allows for an improvement in the spectral resolution. Consequently, more information on chain linking can be obtained, thus facilitating the determination of the stereo sequences. (author)

  13. Depot-medication compliance for patients with psychotic disorders: the importance of illness insight and treatment motivation.

    2016-01-01

    Noncompliance is a major problem for patients with a psychotic disorder. Two important risk factors for noncompliance that have a severe negative impact on treatment outcomes are impaired illness insight and lack of motivation. Our cross-sectional study explored how they are related to each other and their compliance with depot medication. Interviews were conducted in 169 outpatients with a psychotic disorder taking depot medication. Four patient groups were defined based on low or high illness insight and on low or high motivation. The associations between depot-medication compliance, motivation, and insight were illustrated using generalized linear models. Generalized linear model showed a significant interaction effect between motivation and insight. Patients with poor insight and high motivation for treatment were more compliant (94%) (95% confidence interval [CI]: 1.821, 3.489) with their depot medication than patients with poor insight and low motivation (61%) (95% CI: 0.288, 0.615). Patients with both insight and high motivation for treatment were less compliant (73%) (95% CI: 0.719, 1.315) than those with poor insight and high motivation. Motivation for treatment was more strongly associated with depot-medication compliance than with illness insight. Being motivated to take medication, whether to get better or for other reasons, may be a more important factor than having illness insight in terms of improving depot-medication compliance. Possible implications for clinical practice are discussed.

  14. Community Respiratory Viruses as a Cause of Lower Respiratory Tract Infections Following Suppressive Chemotherapy in Cancer Patients

    2005-01-01

    Community respiratory viruses are an important cause of respiratory disease in the immunocompromised patients with cancer. To evaluate the occurrence and clinical significance of respiratory virus infections in hospitalized cancer patients at National Cancer Institute, Cairo University, during anticancer treatment, we studied cases that developed episodes of lower respiratory tract infections (LRTI). Patients and Methods: Thirty patients with LRTI were studied clinically, radiologically, and microbiologically. Sputum cultures were done and an immunofluorescence search for IgM antibodies of influenza A and B, parainfluenza serotypes 1,2 and 3, adenovirus, respiratory syncytial virus, Legionella pneumophila, Coxiella burnettii, Chlamydia pneumoniae, and Mycoplasma pneumoniae were performed on serum samples of patients. The main presenting symptom was cough and expectoration. Hematologic malignancy was the underlying disease in 86.6% of cases. Blood cultures were positive in II patients (36.6%) only. Sputum cultures revealed a bacterial pathogen in [3 cases and fungi in 3; whereas viral and atypical bacterial lgM antibodies were detected in 13 and 4 patients; respectively. Influenza virus was the commonest virus detected, being of type B in 4 cases, type A in one case and mixed A and B in another 5 cases; followed by RSV in 5 patients. Taken together, bacteria were identified as a single cause of LRTI in 10 cases, viruses in 6, fungi in 3 and mixed causes in 7. Still, there were 4 undiagnosed cases. This study showed that respiratory viruses are common in LRTI, either as a single cause or mixed with bacterial pathogens. in hospitalized cancer patients receiving chemotherapy. Diagnostic tests for respiratory viruses should be incorporated in the routine diagnostic study of patients with hematologic malignancies. Also, it must be emphasized that early CT chest is crucial as a base-line prior to initiation of anti-fungal or anti-viral therapy. In cancer patients with a

    Full Text Available Objectives: Evidence of mitochondrial respiratory chain (MRC dysfunction and oxidative stress has been implicated in the pathophysiology of multiple sclerosis (MS. However, at present, there is no reliable low invasive surrogate available to evaluate mitochondrial function in these patients. In view of the particular sensitivity of MRC complex IV to oxidative stress, the aim of this study was to assess blood mononuclear cell (BMNC MRC complex IV activity in MS patients and compare these results to age matched controls and MS patients on β-interferon treatment. Methods: Spectrophotometric enzyme assay was employed to measure MRC complex IV activity in blood mononuclear cell obtained multiple sclerosis patients and aged matched controls. Results: MRC Complex IV activity was found to be significantly decreased (p < 0.05 in MS patients (2.1 ± 0.8 k/nmol × 10−3; mean ± SD] when compared to the controls (7.2 ± 2.3 k/nmol × 10−3. Complex IV activity in MS patients on β-interferon (4.9 ± 1.5 k/nmol × 10−3 was not found to be significantly different from that of the controls. Conclusions: This study has indicated evidence of peripheral MRC complex IV deficiency in MS patients and has highlighted the potential utility of BMNCs as a potential means to evaluate mitochondrial function in this disorder. Furthermore, the reported improvement of complex IV activity may provide novel insights into the mode(s of action of β-interferon.

  18. Respiratory difficulties and breathing disorders in achondroplasia.

    Afsharpaiman, S; Saburi, A; Waters, Karen A

    2013-12-01

    Respiratory difficulties and breathing disorders in achondroplasia are thought to underlie the increased risk for sudden infant death and neuropsychological deficits seen in this condition. This review evaluates literature regarding respiratory dysfunctions and their sequelae in patients with achondroplasia. The limited number of prospective studies of respiratory disease in achondroplasia means that observational studies and case series provide a large proportion of the data regarding the spectrum of respiratory diseases in achondroplasia and their treatments. Amongst clinical respiratory problems described, snoring is the commonest observed abnormality, but the reported incidence of obstructive sleep apnoea (OSA) shows wide variance (10% to 75%). Reported treatments of OSA include adenotonsillectomy, the use of CPAP, and surgical improvement of the airway, including mid-face advancement. Otolaryngologic manifestations are also common. Respiratory failure due to small thoracic volumes is reported, but uncommon. Mortality rate at all ages was 2.27 (CI: 1.7-3.0) with age-specific mortality increased at all ages. Sudden death was most common in infants and children. Cardiovascular events are the main cause of mortality in adults. Despite earlier recognition and treatment of respiratory complications of achondroplasia, increased mortality rates and other complications remain high. Future and ongoing evaluation of the prevalence and impact of respiratory disorders, particularly OSA, in achondroplasia is recommended. Crown Copyright © 2013. Published by Elsevier Ltd.

  19. Respiratory disease mortality among uranium miners

    Archer, V.E.; Gillam, J.D.; Wagoner, J.K.

    1976-01-01

    A mortality analysis of a group of white and Indian uranium miners was done by a life-table method. A significant excess of respiratory cancer among both whites and Indians was found. Nonmalignant respiratory disease deaths among the whites are approaching cancer in importance as a cause of death, probably as a result of diffuse parenchymal radiation damage. Exposure-response curves for nonsmokers are linear for both respiratory cancer and ''other respiratory disease''. Cigaret smoking elevates and distorts that curve. Light cigaret smokers appear to be most vulnerable to lung parenchymal damage. The predominant histologic cancer among nonsmokers is small-cell undifferentiated, just as it is among cigaret smokers

    2018-05-01

    Many veterans of the wars in Afghanistan and Iraq have concomitant respiratory conditions and mental health conditions. We wanted to evaluate the association of mental health diagnoses with respiratory disease diagnoses among post-deployment veterans. We conducted a retrospective cohort study of all Afghanistan and Iraq War veterans who were discharged from the military or otherwise became eligible to receive Veterans Health Administration services. The primary exposure was receipt of a mental health diagnosis and the primary outcome was receipt of a respiratory diagnosis as recorded in the electronic health record. We used multivariable adjusted logistic regression to measure the associations of mental health diagnoses with respiratory diagnoses and conducted several analyses exploring the timing of the diagnoses. Among 182,338 post-deployment veterans, 14% were diagnosed with a respiratory condition, 77% of whom had a concomitant mental health diagnosis. The incidence rates were 5,363/100,000 person-years (p-y), 587/100,000 p-y, 1,450/100,000 p-y, and 233/100,000 p-y for any respiratory disease diagnosis, bronchitis, asthma, and chronic obstructive lung disease diagnoses, respectively, after the date of first Veterans Health Administration utilization. Any mental health diagnosis was associated with increased odds for any respiratory diagnosis (adjusted odds ratio 1.41, 95% confidence interval 1.37-1.46). The association of mental health diagnoses and subsequent respiratory disease diagnoses was stronger and more consistent than the converse. Many Afghanistan and Iraq War veterans are diagnosed with both respiratory and mental illnesses. Comprehensive plans that include care coordination with mental health professionals and treatments for mental illnesses may be important for many veterans with respiratory diseases.

    Full Text Available Tropical dry forests (TDFs have been widely transformed by human activities worldwide and the ecosystem services they provide are diminishing. There has been an urgent call for conservation and restoration of the degraded lands previously occupied by TDFs. Restoration experiences aim to recover species diversity and ecological functions. Different restoration strategies have been used to maximize plant performance including weeding, planting or using artificial mulching. In this investigation, we evaluated whether different restoration practices influence animal arrival and the reestablishment of biotic interactions. We particularly evaluated lepidopteran larvae diversity and caterpillar predation on plants established under different restoration treatments (mulching, weeding and control in the Pacific West Coast of México. This study corroborated the importance of plant host identity for lepidopteran presence in a particular area. Lepidopteran diversity and herbivory rates were not affected by the restoration treatment but they were related to tree species. In contrast, caterpillar predation marks were affected by restoration treatment, with a greater number of predation marks in control plots, while caterpillar predation marks among plant species were not significantly different. This study highlights the importance of considering the introduction of high plant species diversity when planning TDF restoration to maximize lepidopteran diversity and ecosystem functioning.

  6. Effects of nasal or pulmonary delivered treatments with an adenovirus vectored interferon (mDEF201 on respiratory and systemic infections in mice caused by cowpox and vaccinia viruses.

    Donald F Smee

    Full Text Available An adenovirus 5 vector encoding for mouse interferon alpha, subtype 5 (mDEF201 was evaluated for efficacy against lethal cowpox (Brighton strain and vaccinia (WR strain virus respiratory and systemic infections in mice. Two routes of mDEF201 administration were used, nasal sinus (5-µl and pulmonary (50-µl, to compare differences in efficacy, since the preferred treatment of humans would be in a relatively small volume delivered intranasally. Lower respiratory infections (LRI, upper respiratory infections (URI, and systemic infections were induced by 50-µl intranasal, 10-µl intranasal, and 100-µl intraperitoneal virus challenges, respectively. mDEF201 treatments were given prophylactically either 24 h (short term or 56d (long-term prior to virus challenge. Single nasal sinus treatments of 10(6 and 10(7 PFU/mouse of mDEF201 protected all mice from vaccinia-induced LRI mortality (comparable to published studies with pulmonary delivered mDEF201. Systemic vaccinia infections responded significantly better to nasal sinus delivered mDEF201 than to pulmonary treatments. Cowpox LRI infections responded to 10(7 mDEF201 treatments, but a 10(6 dose was only weakly protective. Cowpox URI infections were equally treatable by nasal sinus and pulmonary delivered mDEF201 at 10(7 PFU/mouse. Dose-responsive prophylaxis with mDEF201, given one time only 56 d prior to initiating a vaccinia virus LRI infection, was 100% protective from 10(5 to 10(7 PFU/mouse. Improvements in lung hemorrhage score and lung weight were evident, as were decreases in liver, lung, and spleen virus titers. Thus, mDEF201 was able to treat different vaccinia and cowpox virus infections using both nasal sinus and pulmonary treatment regimens, supporting its development for humans.

  7. Respiratory care management information systems.

    Ford, Richard M

    2004-04-01

    Hospital-wide computerized information systems evolved from the need to capture patient information and perform billing and other financial functions. These systems, however, have fallen short of meeting the needs of respiratory care departments regarding work load assessment, productivity management, and the level of outcome reporting required to support programs such as patient-driven protocols. The respiratory care management information systems (RCMIS) of today offer many advantages over paper-based systems and hospital-wide computer systems. RCMIS are designed to facilitate functions specific to respiratory care, including assessing work demand, assigning and tracking resources, charting, billing, and reporting results. RCMIS incorporate mobile, point-of-care charting and are highly configurable to meet the specific needs of individual respiratory care departments. Important and substantial benefits can be realized with an RCMIS and mobile, wireless charting devices. The initial and ongoing costs of an RCMIS are justified by increased charge capture and reduced costs, by way of improved productivity and efficiency. It is not unusual to recover the total cost of an RCMIS within the first year of its operation. In addition, such systems can facilitate and monitor patient-care protocols and help to efficiently manage the vast amounts of information encountered during the practitioner's workday. Respiratory care departments that invest in RCMIS have an advantage in the provision of quality care and in reducing expenses. A centralized respiratory therapy department with an RCMIS is the most efficient and cost-effective way to monitor work demand and manage the hospital-wide allocation of respiratory care services.

  13. The importance of biological oxidation of iron in the aerobic cells of the Wheal Jane pilot passive treatment system.

    Hall, G; Swash, P; Kotilainen, S

    2005-02-01

    The passive treatment system designed to treat the mine water discharge of the abandoned Wheal Jane tin mine in Cornwall consisted of a sequence of artificial wetland cells, an anaerobic cell and a final series of rock filters. Three systems were operated which differed only in the pre-treatment of the mine water before discharge to the aerobic wetland cells. The aerobic cells were designed to promote aerobic oxidation and precipitation of iron which could exceed a concentration of 100 mg/l in the raw mine water discharge. The largest investment of land area was to the artificial wetland cells and it was important to understand the processes of oxidation and precipitation of iron so that the performance of this aspect the pilot passive treatment plant (PPTP) could be managed as efficiently as possible. The generally low pH of the influent mine water and inevitable trend of decreasing pH due to hydrolysis of Fe(III) meant that distinguishing between biotic and abiotic mechanisms was fundamental for further design planning of passive treatment systems. This paper describes these observations.

    1992-09-10

    Based on a retrospective study of the case records of the primary health care services in a small Norwegian coastal community (Finnøy), we found an incidence of 13% for lower respiratory infections in persons aged 70 years or more. Most often the initial medication was penicillin. In 23% of recorded episodes, medication was changed, owing to unsatisfactory response. Overall mortality in the group was 9%. Three out of five deaths occurred in patients terminally ill from other diseases at the time the respiratory infection started. Problems related to diagnosis, management and prevention are discussed.

  15. Acute respiratory distress syndrome

    Marco Confalonieri

    2017-04-01

    Full Text Available Since its first description, the acute respiratory distress syndrome (ARDS has been acknowledged to be a major clinical problem in respiratory medicine. From July 2015 to July 2016 almost 300 indexed articles were published on ARDS. This review summarises only eight of them as an arbitrary overview of clinical relevance: definition and epidemiology, risk factors, prevention and treatment. A strict application of definition criteria is crucial, but the diverse resource-setting scenarios foster geographic variability and contrasting outcome data. A large international multicentre prospective cohort study including 50 countries across five continents reported that ARDS is underdiagnosed, and there is potential for improvement in its management. Furthermore, epidemiological data from low-income countries suggest that a revision of the current definition of ARDS is needed in order to improve its recognition and global clinical outcome. In addition to the well-known risk-factors for ARDS, exposure to high ozone levels and low vitamin D plasma concentrations were found to be predisposing circumstances. Drug-based preventive strategies remain a major challenge, since two recent trials on aspirin and statins failed to reduce the incidence in at-risk patients. A new disease-modifying therapy is awaited: some recent studies promised to improve the prognosis of ARDS, but mortality and disabling complications are still high in survivors in intensive care.

    The aims of part II is to review the current recommended treatment of exercise-induced asthma (EIA), respiratory and allergic disorders in sports, to review the evidence on possible improvement of performance in sports by asthma drugs and to make recommendations for their treatment. The literature cited with respect to the treatment of exercise induced asthma in athletes (and in asthma patients) is mainly based upon the systematic review given by Larsson et al. (Larsson K, Carlsen KH, Bonini S. Anti-asthmatic drugs: treatment of athletes and exercise-induced bronchoconstriction. In: Carlsen KH, Delgado L, Del Giacco S, editors. Diagnosis, prevention and treatment of exercise-related asthma, respiratory and allergic disorders in sports. Sheffield, UK: European Respiratory Journals Ltd, 2005:73-88) during the work of the Task Force. To assess the evidence of the literature regarding use of beta(2)-agonists related to athletic performance, the Task Force searched Medline for relevant papers up to November 2006 using the present search words: asthma, bronchial responsiveness, exercise-induced bronchoconstriction, athletes, sports, performance and beta(2)-agonists. Evidence level and grades of recommendation were assessed according to Sign criteria. Treatment recommendations for EIA and bronchial hyper-responsiveness in athletes are set forth with special reference to controller and reliever medications. Evidence for lack of improvement of exercise performance by inhaled beta(2)-agonists in healthy athletes serves as a basis for permitting their use. There is a lack of evidence of treatment effects of asthma drugs on EIA and bronchial hyper-responsiveness in athletes whereas extensive documentation exists in treatment of EIA in patients with asthma. The documentation on lack of improvement on performance by common asthma drugs as inhaled beta(2)-agonists with relationship to sports in healthy individuals is of high evidence, level (1+).

    Gruis, Kirsten L; Lechtzin, Noah

    2012-09-01

    Respiratory complications are a common cause of morbidity and mortality in amyotrophic lateral sclerosis (ALS). Treatment of respiratory insufficiency with noninvasive ventilation (NIV) improves ALS patients' quality of life and survival. Evidence-based practice guidelines for the management of ALS patients recommend treatment of respiratory insufficiency with NIV as well as consideration of insufflation/exsufflation to improve clearance of airway secretions. Despite these recommendations respiratory therapies remain underused. In this review we provide a practical guide for the clinician to prescribe and manage respiratory therapies for the patient with ALS. Copyright © 2012 Wiley Periodicals, Inc.

  2. Respiratory neuroplasticity - Overview, significance and future directions.

    Fuller, David D; Mitchell, Gordon S

    Neuroplasticity is an important property of the neural system controlling breathing. However, our appreciation for its importance is still relatively new, and we have much to learn concerning different forms of plasticity, their underlying mechanisms, and their biological and clinical significance. In this brief review, we discuss several well-studied models of respiratory plasticity, including plasticity initiated by inactivity in the respiratory system, intermittent and sustained hypoxia, and traumatic injury to the spinal cord. Other aspects of respiratory plasticity are considered in other contributions to this special edition of Experimental Neurology on respiratory plasticity. Finally, we conclude with discussions concerning the biological and clinical significance of respiratory motor plasticity, and areas in need of future research effort. Copyright © 2016.

  3. SBRT of lung tumours: Monte Carlo simulation with PENELOPE of dose distributions including respiratory motion and comparison with different treatment planning systems

    Panettieri, Vanessa; Wennberg, Berit; Gagliardi, Giovanna; Amor Duch, Maria; Ginjaume, Mercè; Lax, Ingmar

    2007-07-01

    The purpose of this work was to simulate with the Monte Carlo (MC) code PENELOPE the dose distribution in lung tumours including breathing motion in stereotactic body radiation therapy (SBRT). Two phantoms were modelled to simulate a pentagonal cross section with chestwall (unit density), lung (density 0.3 g cm-3) and two spherical tumours (unit density) of diameters respectively of 2 cm and 5 cm. The phase-space files (PSF) of four different SBRT field sizes of 6 MV from a Varian accelerator were calculated and used as beam sources to obtain both dose profiles and dose-volume histograms (DVHs) in different volumes of interest. Dose distributions were simulated for five beams impinging on the phantom. The simulations were conducted both for the static case and including the influence of respiratory motion. To reproduce the effect of breathing motion different simulations were performed keeping the beam fixed and displacing the phantom geometry in chosen positions in the cranial and caudal and left-right directions. The final result was obtained by combining the different position with two motion patterns. The MC results were compared with those obtained with three commercial treatment planning systems (TPSs), two based on the pencil beam (PB) algorithm, the TMS-HELAX (Nucletron, Sweden) and Eclipse (Varian Medical System, Palo Alto, CA), and one based on the collapsed cone algorithm (CC), Pinnacle3 (Philips). Some calculations were also carried out with the analytical anisotropic algorithm (AAA) in the Eclipse system. All calculations with the TPSs were performed without simulated breathing motion, according to clinical practice. In order to compare all the TPSs and MC an absolute dose calibration in Gy/MU was performed. The analysis shows that the dose (Gy/MU) in the central part of the gross tumour volume (GTV) is calculated for both tumour sizes with an accuracy of 2-3% with PB and CC algorithms, compared to MC. At the periphery of the GTV the TPSs overestimate

  5. Hypoxemic Respiratory Failure from Acute Respiratory Distress Syndrome Secondary to Leptospirosis

    Shannon M. Fernando

    2017-01-01

    Full Text Available Acute respiratory distress syndrome (ARDS, characterized by hypoxemic respiratory failure, is associated with a mortality of 30–50% and is precipitated by both direct and indirect pulmonary insults. Treatment is largely supportive, consisting of lung protective ventilation and thereby necessitating Intensive Care Unit (ICU admission. The most common precipitant is community-acquired bacterial pneumonia, but other putative pathogens include viruses and fungi. On rare occasions, ARDS can be secondary to tropical disease. Accordingly, a history should include travel to endemic regions. Leptospirosis is a zoonotic disease most common in the tropics and typically associated with mild pulmonary complications. We describe a case of a 25-year-old male with undiagnosed leptospirosis, presenting with fever and severe hypoxemic respiratory failure, returning from a Costa Rican holiday. There was no other organ failure. He was intubated and received lung protective ventilation. His condition improved after ampicillin and penicillin G were added empirically. This case illustrates the rare complication of ARDS from leptospirosis, the importance of taking a travel history, and the need for empiric therapy because of diagnostic delay.

  7. How Successful is Non-Invasive Ventilation Treatment that is Initiated in the Emergency Department in Cases of COPD Exacerbations with Acute Hypercapnic Respiratory Failure? Can We Predict Treatment Failure?

    Meltem Çoban Ağca

    2017-04-01

    Full Text Available Objective: We aimed to investigate the success rate of non-invasive ventilation (NIV in wards and the predictors of failure in cases of chronic obstructive pulmonary disease (COPD-related acute hypercapnic respiratory failure (AHRF. Methods: The was a retrospective study conducted in a tertiary teaching hospital between May 2011 and 2013. Patients who were admitted to the emergency department (ED because of COPD with AHRF were evaluated; 544 patients who initially received NIV in ED and were transferred to wards were included. Patient characteristics, baseline and follow-up pH values, and partial arterial carbon dioxide (PaCO2 values were recorded. Baseline pH values were categorized as severe (pH<7.26, moderate (pH≥7.26–7.30, and mild (pH≥7.30 acidosis. According to the in-hospital outcome, patients were classified in 2 groups: Group 1: home discharge, Group 2: death or intensive care unit transfer. Results: Treatment resulted in success in 477 (88% patients. Albumin levels were significantly low and the mean Charlson index (CI score was significantly high in Group 2. Admission pH and PaCO2 values did not affect the treatment outcome. Patients in Group 2 had higher PaCO2 and lower pH values as well as a lower level of decrease in PaCO2 values within 2 hours of treatment in ED. Similarly, higher PaCO2 and lower pH values at the end of the first day in wards were indicative of NIV failure (p<0.05. Conclusion: The success rate of NIV in wards in cases of AHRF is high. Patients with low albumin levels and higher CI scores have worse response to treatment. pH or PaCO2 values after a few hours of treatment and not the baseline pH or PaCO2 values are better predictors than the baseline pH and PaCO2 values.

    Respiratory physiotherapy plays a key role in the management and treatment of patients with respiratory diseases worldwide, yet this specialty is not well established in Saudi Arabia. To profile the attitudes among physicians and nurses toward physiotherapists working in respiratory care settings in Saudi Arabia. A cross-sectional questionnaire-based study was conducted. A questionnaire was developed consisting of 23 items, which was distributed both electronically and in paper form to physicians and nurses working in hospitals and health-care centers in Saudi Arabia. Physicians and nurses working outside of Saudi Arabia, and other health professionals, were excluded from the study. A total of 284 questionnaires were returned (nurses: n = 158; physicians: n = 126). The majority believed that physiotherapists have the skills to be involved in respiratory care (79.9%, n = 226) and that physiotherapists are an important member of the Intensive Care Unit team (90.4%, n = 255). Most respondents ( n = 232, 82.9%) felt in need of more information regarding the role of physiotherapy within respiratory care; significantly more nurses than physicians believed they needed additional education ( P = 0.002). Specialized physicians were more likely than nonspecialized physicians to refer respiratory patients to physiotherapy ( P Saudi Arabia. The need for further education for physicians and nurses on the role of physiotherapy in respiratory care was highlighted; this would enable physiotherapy to develop and be further integrated into the respiratory care multidisciplinary team.

    conclusion, we have successfully implemented a respiratory correlated CBCT procedure yielding a 4D dataset. With respiratory correlated CBCT on a linear accelerator, the mean position, trajectory, and shape of a moving tumor can be verified just prior to treatment. Such verification reduces respiration induced geometrical uncertainties, enabling safe delivery of 4D radiotherapy such as gated radiotherapy with small margins

    Full Text Available Post-burn skin contractures of the anterior and lateral abdomen and chest may result in respiratory compromise due to limitation of rib excursion. This case report describes a young man with respiratory compromise limiting his daily activity and function, as a result of a 90% burn sustained 6 years previously. Release of his chest and upper abdomen was achieved using “island” scar releases and a cross-linked bovine tendon collagen and glycosaminoglycan and a semi-permeable polysiloxane bilayer matrix dressing (Integra™ followed by subsequent split thickness skin graft. An immediate increase in maximal inspiratory volume was obtained intra-operatively and in the im­mediate post-operative period, and this improvement was sustained after healing of all wounds with subjective relief of the patient’s symptoms.

  11. Performing Aspirin Desensitization in Aspirin-Exacerbated Respiratory Disease.

    Waldram, Jeremy D; Simon, Ronald A

    2016-11-01

    Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic rhinosinusitis with nasal polyps, asthma, and reactions to cyclooxygenase-1-inhibiting drugs. This condition is often refractory to standard medical treatments and results in aggressive nasal polyposis that often requires multiple sinus surgeries. Aspirin desensitization followed by daily aspirin therapy is an important treatment option, and its efficacy has been validated in multiple research studies. Aspirin desensitization is not without risk, but specific protocols and recommendations exist to mitigate the risk. Most patients with AERD can undergo aspirin desensitization in an outpatient setting under the supervision of an allergist. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Despite remarkable progress in survival of children with acute lymphoblastic leukemia (ALL which has reached about 85%, early toxicity and relapse rate remain issues that need to to be resolved. Genetic variants are important factors influencing the metabolism of cytotoxic drugs in ALL treatment. Variants in genes coding for methotrexate (MTX-metabolizing enzymes are under constant scientific interest due to their potential impact on drug toxicity and relapse rate. We investigated methylenetetrahydrofolate reductase (MTHFR c.677C>T and MTHFR c.1298A>C variants as pharmacogenetic markers of MTX toxicity and predictors of relapse. The study enrolled 161 children with ALL, treated according to the current International Berlin-Frankfurt-Munster group (BFM for diagnostics and treatment of leukemia and lymphoma protocols. Genotyping was performed using PCRRFLP and allele-specific PCR assays. Our results revealed similar distributions of MTHFR c.677C>T and MTHFR c.1298A>C genotypes among 104 healthy individuals as compared to pediatric ALL patients. A lower incidence of early MTX toxicity was noted in the MTHFR c.677TT genotype (p=0.017, while MTHFR c.1298A>C genotypes were not associated with MTX toxicity. Carriers of any MTHFR c.677C>T and MTHFR c.1298A>C genotypes did not experience decreased overall survival (OAS or higher relapse rates. Genetic variants in the MTHFR gene are not involved in leukemogenesis in pediatric ALL. The presence of the MTHFR c.677TT genotype was recognized as a predictive factor for decreased MTX toxicity during the intensification phase of therapy. Neither MTHFR c.677C>T nor MTHFR c.1298A>C genotypes correlated with an increased number of toxic deaths or relapse rate. Our study emphasizes the importance of implementing pharmacogenetic markers in order to optimize pediatric ALL therapy.

    Upper respiratory tract infections are the most common causes of medical visits in children and adults, demanding massive use of antibiotics. Bacterial resistance caused by beta-lactamase is one of the most serious problems in this matter. Sultamicillin, a double pro-drug of Ampicillin/Sulbactan, is a potent beta-lactamase inhibitor which can face this challenge. Evaluate efficacy, safety and tolerability of Ampicillin/Sulbactan compared to Amoxicillin/Clavulanate in upper respiratory tract infections in adults. 102 patients were enrolled and randomized to receive Ampicillin/Sulbactan or Amoxicillin/Clavulanate during 10 days. They were evaluated 10 and 30 days after treatment to learn about the therapeutic response. There were no differences between the two groups respecting cure at the end of treatment (visit 2) or at the end of the study (visit 3). Cure ratio was 61.7% and 93.2% (visits 2 and 3) in the Amoxicillin/Clavulanate group compared to 64.4% and 97.4%, respectively, in Ampicillin/Sulbactan group. The adverse events ratio for the two groups was the same (p=0.940). The number of patients with diarrhea was greater in the group of patients receiving Amoxicillin/Clavulanate (70.6%) than in the group receiving Ampicillin/Sulbactan (29.4%) (p=0.0164). Ampicillin/Sulbactan is as safe and efficient as Amoxicillin/Clavulanate in the empiric treatment of upper respiratory infections in adults. The low occurrence of diarrhea in the group receiving Ampicillin/Sulbactan needs confirmation in other studies.

    There is a continuing interest in determining whether it is possible to identify thresholds for chemical allergy. Here allergic sensitisation of the respiratory tract by chemicals is considered in this context. This is an important occupational health problem, being associated with rhinitis and asthma, and in addition provides toxicologists and risk assessors with a number of challenges. In common with all forms of allergic disease chemical respiratory allergy develops in two phases. In the first (induction) phase exposure to a chemical allergen (by an appropriate route of exposure) causes immunological priming and sensitisation of the respiratory tract. The second (elicitation) phase is triggered if a sensitised subject is exposed subsequently to the same chemical allergen via inhalation. A secondary immune response will be provoked in the respiratory tract resulting in inflammation and the signs and symptoms of a respiratory hypersensitivity reaction. In this article attention has focused on the identification of threshold values during the acquisition of sensitisation. Current mechanistic understanding of allergy is such that it can be assumed that the development of sensitisation (and also the elicitation of an allergic reaction) is a threshold phenomenon; there will be levels of exposure below which sensitisation will not be acquired. That is, all immune responses, including allergic sensitisation, have threshold requirement for the availability of antigen/allergen, below which a response will fail to develop. The issue addressed here is whether there are methods available or clinical/epidemiological data that permit the identification of such thresholds. This document reviews briefly relevant human studies of occupational asthma, and experimental models that have been developed (or are being developed) for the identification and characterisation of chemical respiratory allergens. The main conclusion drawn is that although there is evidence that the

    Historically many different drugs have been used to enhance sporting performances. The magic elixir is still elusive and the drugs are still used despite the heavy adverse effects. The respiratory system is regularly involved in this research probably because of its central location in the body with several connections to the cardiovascular system. Moreover people are aware that O2 consumption and its delivery to mitochondria firstly depend on ventilation and on the respiratory exchanges. The second step consists in the tendency to increase V'O2 max and to prolong its availability with the aim of improving the endurance time and to relieve the fatigue. Many methods and substances had been used in order to gain an artificial success. Additional oxygen, autologous and homologous transfusion and erythropoietin, mainly the synthetic type, have been administered with the aim of increasing the amount of oxygen being delivered to the tissues. Some compounds like stimulants and caffeine are endowed of excitatory activity on the CNS and stimulate pulmonary ventilation. They did not prove to have any real activity in supporting the athletic performances. Beta-adrenergic drugs, particularly clenbuterol, when administered orally or parenterally develop a clear illicit activity on the myosin fibres and on the muscles as a whole. Salbutamol, terbutaline, salmeterol and formoterol are legally admitted when administrated by MDI in the treatment of asthma. The prevalence of asthma and bronchial hyperactivity is higher in athletes than amongst the general population. This implies that clear rules must be provided to set a correct diagnosis of asthma in the athletes and a correct therapy to align with the actual guidelines according to the same rights of the "other" asthmatic patients.

    symptoms (nausea, vomiting, itching, altered defecation after receiving medicinal plant its use should be discontinued; pediatricians should not recommend using herbs with potential toxic effects (for example, high concentrations or prolonged use of shoots of wild rosemary, tansy and other. The dosage is a very important question, which depends on the age of a child. The scheme proposed by N.P. Menshikova et al. is convenient for practice. The daily dose in terms of dry plant material is: for сhildren under 1 year old — 1/2 teaspoon, from 1 to 3 years — 1 teaspoon, 3 to 6 years — 1 dessert spoon, 6 to 10 years — 1 tablespoon, 10 and older — 1–2 tablespoons. In case of the appointment of herbal me­dicine pediatrician should take into account the characteristics of the therapeutic effects of medicinal plants, their dosing and possible side effects; it is necessary to monitor treatment to assess its efficacy and safety. In the treatment of respiratory diseases inhalation is effective, using inhalation devices. Aerosol inhalation for treatment of respiratory disease may have different effects: antiseptic, anti-inflammatory, a bronchodilator, and may promote the liquefaction of sputum evacuation, improve the function of the ciliated epithelium. For the purpose of inhalations medicinal plants containing essential oils are used: Calendula, Peppermint, Chamomile, Salvia, Eucalyptus, Thyme, birch, Plantain. The first inhalation lasts for 1–2 minu­tes and later 5–10 minutes. Also ready officinal herbal drugs can be used in pediatric practice: essential oils, teas, juices. A good effect of essential oil of Peppermint, Eucalyptus, Salvia and others, tincture of Calendula, Eucalyptus, Salvia, Peppermint. Relative contraindications are considered: a allergic conditions in children, b acute, life-threatening conditions and diseases, c pregnancy — for medicinal plants causing changes in hormonal balance.

Age, sex, race, age at the first evidence of leukocoria and who noticed it, ages at diagnosis and phacectomy, family history of cataract, intraocular lens implantation, visual acuity (VA and optic prescription were evaluated. RESULTS: There were 44 patients. The age ranged from 0-15 years: 19 (43.0% 0-3, 14 (32.0% 4-10 and 11 (25.0% from 11-15 years. Twenty-eight (63.6% were female and 19 (43.2% leukodermic. The first evidence of leukocoria was observed by the mother in 17 patients (38.6%. Leukocoria was observed in the first 2 months of life in 45.5% of the patients; phacectomy was performed in 43.2% of the patients with more than 1 year of age. Optic prescription was performed in 61.4% of the cases with 9.1% of the patients below 1 year of age. Intraocular lens was implanted in 13.6% and 4 patients (9.1% had a family history of congenital cataract. In 20.4% VA was lower than 20/400 and secondary glaucoma was observed in 18.2% of the cases. Low vision aids included two glasses and one telescope. CONCLUSION: More information about congenital cataract should be provided for families and pediatricians, and early surgical treatment, optic correction and treatment of amblyopia should be performed promptly.

  19. Neurological Respiratory Failure

    Full Text Available West Nile virus infection in humans is mostly asymptomatic. Less than 1% of neuro-invasive cases show a fatality rate of around 10%. Acute flaccid paralysis of respiratory muscles leading to respiratory failure is the most common cause of death. Although the peripheral nervous system can be involved, isolated phrenic nerve palsy leading to respiratory failure is rare and described in only two cases in the English literature. We present another case of neurological respiratory failure due to West Nile virus-induced phrenic nerve palsy. Our case reiterates the rare, but lethal, consequences of West Nile virus infection, and the increase of its awareness among physicians.

  20. Acute respiratory distress syndrome 40 years later: time to revisit its definition.

    Phua, Jason; Stewart, Thomas E; Ferguson, Niall D

    2008-10-01

    Acute respiratory distress syndrome is a common disorder associated with significant mortality and morbidity. The aim of this article is to critically evaluate the definition of acute respiratory distress syndrome and examine the impact the definition has on clinical practice and research. Articles from a MEDLINE search (1950 to August 2007) using the Medical Subject Heading respiratory distress syndrome, adult, diagnosis, limited to the English language and human subjects, their relevant bibliographies, and personal collections, were reviewed. The definition of acute respiratory distress syndrome is important to researchers, clinicians, and administrators alike. It has evolved significantly over the last 40 years, culminating in the American-European Consensus Conference definition, which was published in 1994. Although the American-European Consensus Conference definition is widely used, it has some important limitations that may impact on the conduct of clinical research, on resource allocation, and ultimately on the bedside management of such patients. These limitations stem partially from the fact that as defined, acute respiratory distress syndrome is a heterogeneous entity and also involve the reliability and validity of the criteria used in the definition. This article critically evaluates the American-European Consensus Conference definition and its limitations. Importantly, it highlights how these limitations may contribute to clinical trials that have failed to detect a potential true treatment effect. Finally, recommendations are made that could be considered in future definition modifications with an emphasis on the significance of accurately identifying the target population in future trials and subsequently in clinical care. How acute respiratory distress syndrome is defined has a significant impact on the results of randomized, controlled trials and epidemiologic studies. Changes to the current American-European Consensus Conference definition are

    Background Cardiac arrests are a major public health concern worldwide. The extent and types of randomized controlled trials (RCTs) – our most reliable source of clinical evidence – conducted in these high-risk patients over recent years are largely unknown. Methods and Results We performed a systematic review, identifying all RCTs published in PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Library from 1995 to 2014 that focused on acute treatment of non-traumatic cardiac arrest in adults. We then extracted data on the setting of study populations, types and timing of interventions studied, risk of bias, outcomes reported and how these factors have changed over time. Over this twenty-year period, 92 RCTs were published containing 64,309 patients (median, 225.5 per trial). Of these, 81 RCTs (88.0%) involved out-of-hospital cardiac arrest whereas 4 (4.3%) involved in-hospital cardiac arrest and 7 (7.6%) included both. Eighteen RCTs (19.6%) were performed in the U.S., 68 (73.9%) were performed outside the U.S., and 6 (6.5%) were performed in both settings. Thirty-eight RCTs (41.3%) evaluated drug therapy, 39 (42.4%) evaluated device therapy, and 15 (16.3%) evaluated protocol improvements. Seventy-four RCTs (80.4%) examined interventions during the cardiac arrest, 15 (16.3%) examined post-cardiac arrest treatment, and 3 (3.3%) studied both. Overall, reporting of risk of bias was limited. The most common outcome reported was ROSC: 86 (93.5%) with only 22 (23.9%) reporting survival beyond 6 months. Fifty-three RCTs (57.6%) reported global ordinal outcomes whereas 15 (16.3%) reported quality-of-life. RCTs in the last 5 years were more likely to be focused on protocol improvement and post-cardiac arrest care. Conclusions Important gaps in RCTs of cardiac arrest treatments exist, especially those examining in-hospital cardiac arrest, protocol improvement, post-cardiac arrest care, and long-term or quality-of-life outcomes.

    Full Text Available The human respiratory syncytial virus (hRSV and the human metapneumovírus (hMPV are main etiological agents of acute respiratory infections (ARI. The ARI is an important cause of childhood morbidity and mortality worldwide.  hRSV and hMPV are members of the Paramyxoviridae. They are enveloped, non-segmented viruses, with negative-sense single stranded genomes. Respiratory syncytial virus (hRSV is the best characterized agent viral of this group, associated with respiratory diseases in lower respiratory tract. Recently, a new human pathogen belonging to the subfamily Pneumovirinae was identified, the human metapneumovirus (hMPV, which is structurally similar to the hRSV, in genomic organization, viral structure, antigenicity and clinical symptoms.  The subfamily Pneumovirinae contains two genera: genus Pneumovirus contains hRSV, the bovine (bRSV, as well as the ovine and caprine respiratory syncytial virus and pneumonia virus of mice, the second genus Metapneumovirus, consists of avian metapneumovirus (aMPV and human metapneumovirus (hMPV. In this work, we present a brief narrative review of the literature on important aspects of the biology, epidemiology and clinical manifestations of infections by two respiratory viruses.

    Full Text Available Household air pollution (HAP and chronic HIV infection are each associated with significant respiratory morbidity. Little is known about relationships between HAP and respiratory symptoms among people living with HIV. The objective of this study was to investigate the relationship between cooking fuel type and chronic respiratory symptoms in study participants from the Uganda AIDS Rural Treatment Outcomes Study. Study participants were enrolled at the time of antiretroviral therapy initiation and seen quarterly from 2005 to 2014 for health-focused questionnaires, CD4 count and HIV viral load. We used multivariable logistic regression and generalised estimating equations, with each study visit as a unit of observation, to investigate relationships between cooking fuel type and chronic respiratory symptoms. We observed an association between cooking with firewood (versus charcoal and chronic cough among HIV-infected females in rural Uganda (adjusted OR 1.41, 95% CI 1.00–1.99; p=0.047. We did not observe an association between cooking fuel type and respiratory symptoms among males (adjusted OR 0.88, 95% CI 0.47–1.63; p=0.658. Associations between cooking fuel and chronic cough in this HIV-infected cohort may be influenced by sex-based roles in meal preparation. This study raises important questions about relationships between household air pollution, HIV infection and respiratory morbidity.

    2009-01-01

    Our aim is to investigate the impact of respiratory motion on tumor quantification and delineation in static PET/CT imaging using a population of patient respiratory traces. A total of 1295 respiratory traces acquired during whole body PET/CT imaging were classified into three types according to the qualitative shape of their signal histograms. Each trace was scaled to three diaphragm motion amplitudes (6 mm, 11 mm and 16 mm) to drive a whole body PET/CT computer simulation that was validated with a physical phantom experiment. Three lung lesions and one liver lesion were simulated with diameters of 1 cm and 2 cm. PET data were reconstructed using the OS-EM algorithm with attenuation correction using CT images at the end-expiration phase and respiratory-averaged CT. The errors of the lesion maximum standardized uptake values (SUV max ) and lesion volumes between motion-free and motion-blurred PET/CT images were measured and analyzed. For respiration with 11 mm diaphragm motion and larger quiescent period fraction, respiratory motion can cause a mean lesion SUV max underestimation of 28% and a mean lesion volume overestimation of 130% in PET/CT images with 1 cm lesions. The errors of lesion SUV max and volume are larger for patient traces with larger motion amplitudes. Smaller lesions are more sensitive to respiratory motion than larger lesions for the same motion amplitude. Patient respiratory traces with relatively larger quiescent period fraction yield results less subject to respiratory motion than traces with long-term amplitude variability. Mismatched attenuation correction due to respiratory motion can cause SUV max overestimation for lesions in the lower lung region close to the liver dome. Using respiratory-averaged CT for attenuation correction yields smaller mismatch errors than those using end-expiration CT. Respiratory motion can have a significant impact on static oncological PET/CT imaging where SUV and/or volume measurements are important. The impact

    Purpose: Respiratory margins for partial breast irradiation (PBI) have been largely based on geometric observations, which may overestimate the margin required for dosimetric coverage. In this study, dosimetric population-based respiratory margins and margin formulas for external beam partial breast irradiation are determined. Methods: Volunteer respiratory data and anterior–posterior (AP) dose profiles from clinical treatment plans of 28 3D conformal radiotherapy (3DCRT) PBI patient plans were used to determine population-based respiratory margins. The peak-to-peak amplitudes (A) of realistic respiratory motion data from healthy volunteers were scaled from A = 1 to 10 mm to create respiratory motion probability density functions. Dose profiles were convolved with the respiratory probability density functions to produce blurred dose profiles accounting for respiratory motion. The required margins were found by measuring the distance between the simulated treatment and original dose profiles at the 95% isodose level. Results: The symmetric dosimetric respiratory margins to cover 90%, 95%, and 100% of the simulated treatment population were 1.5, 2, and 4 mm, respectively. With patient set up at end exhale, the required margins were larger in the anterior direction than the posterior. For respiratory amplitudes less than 5 mm, the population-based margins can be expressed as a fraction of the extent of respiratory motion. The derived formulas in the anterior/posterior directions for 90%, 95%, and 100% simulated population coverage were 0.45A/0.25A, 0.50A/0.30A, and 0.70A/0.40A. The differences in formulas for different population coverage criteria demonstrate that respiratory trace shape and baseline drift characteristics affect individual respiratory margins even for the same average peak-to-peak amplitude. Conclusions: A methodology for determining population-based respiratory margins using real respiratory motion patterns and dose profiles in the AP direction was

    Different aspects of self-stigmatization represent barriers for recovery in patients with psychosis disorders. It is unclear whether addressing patient's competence and control beliefs could attenuate the extent of self-stigmatization. The major aim of this study was to identify predictors of self-stigmatization derived from competence and control beliefs in patients (N = 80). Sociodemographic characteristics, clinical variables, competence and control beliefs and self-stigmatization were assessed among 80 patients with psychosis disorders. The cross-sectional data was analyzed by correlation and regression analyses. Results indicate deficits in self-concept of own competences, i.e. the capability of acting in new, difficult or ambiguous situations, resulting in also impaired self-efficacy and relatively increased externality in patients compared to a general population sample. Subjective well-being under neuroleptics, trait-anxiety and defining oneself as religious were the most influential predictors of competence and control beliefs. A weaker self-concept of own competences was also revealed as the strongest predictor of overall high self-stigmatization. Our results stress the importance of orienting treatment strategies towards strengthening the self-concept of own competences in patients in order to reduce self-stigmatization and enhance resilience.

    Systemic arterial hypertension (SAH) is one of the most common conditions seen in primary care of cardiovascular disease and whose consequences; depending on the "target organ" affecting produce ischemic heart disease, cerebral vascular disease or chronic kidney disease. In the pathogenesis of HAS are several physiopathological mechanisms involved; of which currently, to name the most important and frequent play a role in increasing adrenaline levels, the renin-angiotensin-aldosterone system and recently, much the participation of insulin resistance and hyperinsulinemia mentioned. These processes lead to an imbalance between the sympathetic and parasympathetic tone, coupled with hypersensitivity sodium trigger one of the pathophysiologic mechanisms of hypertension. SAH is currently defined as finding numbers of older blood pressure 140/90mm Hg. This is one of the diseases that most affect the world population prevalences found in age and gender groups 45 to 55% in men between 45 and 70 years and 45 to 65% in women of the same age group. In 2013 most recent clinical guidelines for treatment and the recommended goals, which has managed to reduce its complications and mortality were published; among which include vascular diseases such as ischemic heart and brain and kidney. In this paper a case that exemplifies the secondary complications in late diagnosis, damage to "target organ" by long-term exposure and inadequate compliance with therapeutic goals discussed.

  11. Interferon therapy of acute respiratory viral infections in children

    A.E. Abaturov

    2017-04-01

    end of therapy, we calculated the proportion of patients in groups, who didn’t have clinical signs of acute respiratory viral infection (more than 1 point after 5 days of treatment. The effectiveness of therapy with Laferobionum® was 100 %. The effectiveness of treatment with Laferobionum® depended to some extent on the etiology of the disease: in acute respiratory viral infections caused by the respiratory syncytial virus, there was less significant effect of interferon therapy on the course of the disease than in acute respiratory infections caused by influenza and parainfluenza viruses. Given the absence of subjective complaints from the examinees and negative changes in an objective and laboratory examination, tolerability of treatment in all patients receiving Laferobionum® was regarded as “good”. Conclusions. Interferon therapy, in particular the use of recombinant α-2b interferons (Laferobionum®, is one of the most important components of the treatment for acute respiratory viral diseases in children. The use of interferon for intranasal administration, which contributes to the sanogenesis of acute respiratory infections, will accelerate the process of recovery, prevent the development of bacterial complications.

  12. Respiratory physiology during early life.

    Stocks, J

    1999-08-01

    Despite the rapid adaptation to extrauterine life, the respiratory system of an infant is not simply a miniaturized version of that of an adult, since the rapid somatic growth that occurs during the first year of life is accompanied by major developmental changes in respiratory physiology. The highly compliant chest wall of the infant results in relatively low transpulmonary pressures at end expiration with increased tendency of the small peripheral airways to close during tidal breathing. This not only impairs gas exchange and ventilation-perfusion balance, particularly in dependent parts of the lung, but, together with the small absolute size of the airways, renders the infant and young child particularly susceptible to airway obstruction. Premature airways are highly compliant structures compared with those of mature newborns or adults. This increased compliance can cause airway collapse, resulting in increased airways resistance, flow limitation, poor gas exchange and increased work of breathing. Although there is clear evidence that airway reactivity is present from birth, its role in wheezing lower respiratory tract illnesses in young infants may be overshadowed by pre-existing abnormalities of airway geometry and lung mechanics, or by pathological changes such as airway oedema and mucus hypersecretion. Attempts to assess age-related changes in airway reactivity or response to aerosol therapy in the very young is confounded by changes in breathing patterns and the fact that infants are preferential nose breathers. There is increasing evidence that pre-existing abnormalities of respiratory function, associated with adverse events during foetal life (including maternal smoking during pregnancy), and familial predisposition to wheezing are important determinants of wheezing illnesses during the first years of life. This emphasizes the need to identify and minimize any factors that threaten the normal development of the lung during this critical period if

  13. Hypnosis in paediatric respiratory medicine.

    McBride, Joshua J; Vlieger, Arine M; Anbar, Ran D

    2014-03-01

    Hypnotherapy is an often misunderstood yet effective therapy. It has been reported to be useful within the field of paediatric respiratory medicine as both a primary and an adjunctive therapy. This article gives a brief overview of how hypnotherapy is performed followed by a review of its applications in paediatric patients with asthma, cystic fibrosis, dyspnea, habit cough, vocal cord dysfunction, and those requiring non-invasive positive pressure ventilation. As the available literature is comprised mostly of case series, retrospective studies, and only a single small randomized study, the field would be strengthened by additional randomized, controlled trials in order to better establish the effectiveness of hypnosis as a treatment, and to identify the processes leading to hypnosis-induced physiologic changes. As examples of the utility of hypnosis and how it can be taught to children with respiratory disease, the article includes videos that demonstrate its use for patients with cystic fibrosis.

  14. Evaluation of the effect of non-surgical periodontal treatment on oral health-related quality of life: estimation of minimal important differences 1 year after treatment.

    Jönsson, Birgitta; Öhrn, Kerstin

    2014-03-01

    To evaluate an individually tailored oral health educational programme on patient-reported outcome compared with a standard oral health educational programme, assess change over time and determine minimal important differences (MID) in change scores for two different oral health related quality of life (OHRQoL) instrument after non-surgical periodontal treatment (NSPT). In a randomized controlled trial evaluating two educational programmes, patients (n = 87) with chronic periodontitis completed a questionnaire at baseline and after 12 months. OHRQoL was assessed with the General Oral Health Assessment Index (GOHAI) and the UK oral health-related quality-of-life measure (OHQoL-UK). In addition, patients' global rating of oral health and socio-demographic variables were recorded. The MID was estimated with anchor-based and distributions-based methods. There were no differences between the two educational groups. The OHRQoL was significantly improved after treatment. The MID was approximately five for OHQoL-UK with a moderate ES, and three for GOHAI with a Small ES, and 46-50% of the patients showed improvements beyond the MID. Both oral health educational groups reported higher scores in OHRQoL after NSPT resulting in more positive well-being (OHQoL-UK) and less frequent oral problems (GOHAI). OHQoL-UK gave a greater effect size and mean change scores but both instruments were associated with the participants' self-rated change in oral health. The changes were meaningful for the patients supported by the estimated MID. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available A fenilcetonúria (PKU é o mais comum dos erros congênitos do metabolismo de aminoácidos. Resulta da deficiência da fenilalanina hidroxilase, enzima que catalisa a conversão de fenilalanina em tirosina. A introdução de uma dieta com baixo teor de fenilalanina deve ter início nos primeiros meses de vida, de preferência no primeiro mês, para evitar o retardo mental, manifestação clínica mais severa da doença. Foi elaborada revisão sobre essa temática, que aborda desde a PKU clássica até a hiperfenilalaninemia branda, incluindo relato sobre a PKU maternal e os efeitos da exposição do útero a altos níveis de fenilalanina sobre o feto.Phenylketonuria is the most common inborn error of amino acid metabolism. It is due to a deficiency of phenylalanine hydroxylase, which normally converts phenylalanine to tyrosine. A diet low in phenylalanine starting in the first month of life can significantly reduce mental retardation, the most important feature of the disease. The aim of the review is to discuss the difficulties found in the diagnosis of PKU and its variants, ranging from classic phenylketonuria to mild hyperphenylalaninaemia, and the effects of dietary restriction of phenylalanine on the growth and development of children. Also, we present the current controversies about the age of discontinuing the dietary treatment. This review summarizes the benefits and problems emerging from a prolonged therapy taking into account dietary compliance in different age groups, and discusses dietary alternatives to the synthetic amino acid mixtures free of phenylalanine, based on low phenylalanine protein hydrolysates. In addition, we show some information about the effects of maternal phenylketonuria on pregnancy outcome and infant development, if exposed to high phenylalanine levels intra uterineo.

  17. Management of respiratory symptoms in ALS.

    Hardiman, Orla

    2012-02-01

    Respiratory insufficiency is a frequent feature of ALS and is present in almost all cases at some stage of the illness. It is the commonest cause of death in ALS. FVC is used as important endpoint in many clinical trials, and in decision-making events for patients with ALS, although there are limitations to its predictive utility. There are multiple causes of respiratory muscle failure, all of which act to produce a progressive decline in pulmonary function. Diaphragmatic fatigue and weakness, coupled with respiratory muscle weakness, lead to reduced lung compliance and atelectasis. Increased secretions increase the risk of aspiration pneumonia, which further compromises respiratory function. Bulbar dysfunction can lead to nutritional deficiency, which in turn increases the fatigue of respiratory muscles. Early recognition of respiratory decline and symptomatic intervention, including non-invasive ventilation can significantly enhance both quality of life and life expectancy in ALS. Patients with respiratory failure should be advised to consider an advance directive to avoid emergency mechanical ventilation.

    2016-06-15

    Purpose: To assess the dose deposition in simulated single-fraction MR-Linac treatments of renal cell carcinoma, when inter-cycle respiratory motion variation is taken into account using online MRI. Methods: Three motion characterization methods, with increasing complexity, were compared to evaluate the effect of inter-cycle motion variation and drifts on the accumulated dose for an SBRT kidney MR-Linac treatment: 1) STATIC, in which static anatomy was assumed, 2) AVG-RESP, in which 4D-MRI phase-volumes were time-weighted, based on the respiratory phase and 3) PCA, in which 3D volumes were generated using a PCA-model, enabling the detection of inter-cycle variations and drifts. An experimental ITV-based kidney treatment was simulated in a 1.5T magnetic field on three volunteer datasets. For each volunteer a retrospectively sorted 4D-MRI (ten respiratory phases) and fast 2D cine-MR images (temporal resolution = 476ms) were acquired to simulate MR-imaging during radiation. For each method, the high spatio-temporal resolution 3D volumes were non-rigidly registered to obtain deformation vector fields (DVFs). Using the DVFs, pseudo-CTs (generated from the 4D-MRI) were deformed and the dose was accumulated for the entire treatment. The accuracies of all methods were independently determined using an additional, orthogonal 2D-MRI slice. Results: Motion was most accurately estimated using the PCA method, which correctly estimated drifts and inter-cycle variations (RMSE=3.2, 2.2, 1.1mm on average for STATIC, AVG-RESP and PCA, compared to the 2DMRI slice). Dose-volume parameters on the ITV showed moderate changes (D99=35.2, 32.5, 33.8Gy for STATIC, AVG-RESP and PCA). AVG-RESP showed distinct hot/cold spots outside the ITV margin, which were more distributed for the PCA scenario, since inter-cycle variations were not modeled by the AVG-RESP method. Conclusion: Dose differences were observed when inter-cycle variations were taken into account. The increased inter

    Mugford Miranda

    2006-12-01

    Full Text Available Abstract Background An estimated 350 adults develop severe, but potentially reversible respiratory failure in the UK annually. Current management uses intermittent positive pressure ventilation, but barotrauma, volutrauma and oxygen toxicity can prevent lung recovery. An alternative treatment, extracorporeal membrane oxygenation, uses cardio-pulmonary bypass technology to temporarily provide gas exchange, allowing ventilator settings to be reduced. While extracorporeal membrane oxygenation is proven to result in improved outcome when compared to conventional ventilation in neonates with severe respiratory failure, there is currently no good evidence from randomised controlled trials to compare these managements for important clinical outcomes in adults, although evidence from case series is promising. Methods/Design The aim of the randomised controlled trial of Conventional ventilatory support vs extracorporeal membrane oxygenation for severe adult respiratory failure (CESAR is to assess whether, for patients with severe, but potentially reversible, respiratory failure, extracorporeal membrane oxygenation will increase the rate of survival without severe disability ('confined to bed' and 'unable to wash or dress' by six months post-randomisation, and be cost effective from the viewpoints of the NHS and society, compared to conventional ventilatory support. Following assent from a relative, adults (18–65 years with severe, but potentially reversible, respiratory failure (Murray score ≥ 3.0 or hypercapnea with pH Discussion Analysis will be based on intention to treat. A concurrent economic evaluation will also be performed to compare the costs and outcomes of both treatments.

  1. Intensity cut-points for the Respiratory Distress Observation Scale

    Campbell, Margaret L; Templin, Thomas N

    2015-01-01

    Background The Respiratory Distress Observation Scale© is an innovative solution to assessment when a dyspnea report cannot be elicited. The Respiratory Distress Observation Scale has acceptable reliability and validity psychometrics. Aim To identify distress-intensity cut-points of the Respiratory Distress Observation Scale. Design Receiver operating characteristic curve analysis was conducted with inpatients stratified by four levels of respiratory distress—none, mild, moderate, or severe. Patients provided three self-report measures of dyspnea: dichotomous (yes/no); a ranking of none, mild, moderate, or severe; and a numerical rating scale. Respiratory distress was assessed using the Respiratory Distress Observation Scale instrument. Setting/participants Participants were 136 adult inpatients, mean age 61.8 years (standard deviation = 13.18 years), 89.7% African American, and 56.6% female, who were recruited from an urban, tertiary care hospital in the Midwest of the United States. Results In all, 47% (n = 64) self-reported dyspnea (yes/no). Ranking was distributed as follows: none = 36, mild = 35, moderate = 40, and severe = 25. Numerical rating scale scores ranged from 0 to 10, mean = 4.99 (standard deviation = 2.9). Respiratory Distress Observation Scale scores ranged from 0 to 7, median (interquartile range) = 2 (1–3). Receiver operating characteristic curve analysis–determined Respiratory Distress Observation Scale score of 0–2 suggests little or no respiratory distress; score ≥3 signified moderate to severe distress. Conclusion A Respiratory Distress Observation Scale score ≥3 signifies a patient’s need for palliation of respiratory distress. An end-point for identifying responsiveness to treatment, in other words, respiratory comfort, is Respiratory Distress Observation Scale <3. Because patients with imminent respiratory failure, as typified by dying patients, were not represented yielding lower than expected Respiratory Distress

    Full Text Available Objective To investigate the effect of respiratory function training on respiratory function and conscious state of patients with severe cerebrovascular disease (SCVD.  Methods A total of 27 patients with SCVD were divided into control group (N = 17 and observation group (N = 10. Control group received routine drug and rehabilitation treatment, and observation group was added respiratory function training based on routine treatment. The respiratory rate, tidal volume (TV, heart rate, blood pressure and artery oxygen saturation (SaO2 of patients were monitored by breathing machine before and after 4-week treatment. Meanwhile, arterial blood gas analysis was used to detect arterial partial pressure of oxygen (PaO2, oxygenation index, partial pressure of carbon dioxide (PaCO2 and pH value. At the same time, Glasgow Coma Scale (GCS was used to evaluate the conscious state of patients.  Results All patients successfully completed 4-week rehabilitation training, without asphyxia, arrhythmia or other adverse events. Compared with before training, the respiratory rate (P = 0.006 and pH value (P = 0.010 were significantly decreased, while SaO2 (P = 0.001, oxygenation index (P = 0.000 and GCS scores (P = 0.004, 0.017 were significantly increased in both groups of patients after training. There was no statistically significant difference between 2 groups on respiratory function indexes and GCS scores after training (P > 0.05, for all. Conclusions Respiratory function training did not significantly improve the respiratory function and conscious state of patients with SCVD, yet to be further studied. Randomized controlled clinical trials with larger, layered samples and long-term prognosis observation are needed. Examination method of respiratory function of SCVD patients is also a topic to be explored.  DOI: 10.3969/j.issn.1672-6731.2017.04.007

  7. Assessing the impact of a respiratory diagnosis on smoking cessation.

    Jones, Alexandra

    2017-07-27

    The aim of this study was to assess the impact of respiratory diagnoses on smoking cessation. A total of 229 current and former smokers, with and without respiratory diagnoses completed an anonymous online questionnaire assessing how their smoking habit changed when diagnosed with various respiratory conditions. Among all participants the most common reason for quitting smoking was to reduce the risk of health problems in general. In those with a chronic respiratory diagnosis, this was their most common reason for quitting. Motivation to quit smoking, scored by participants on a scale of 0-10, increased at the time of diagnosis then further increased after diagnosis of a chronic respiratory condition but declined after diagnosis of an acute respiratory condition. The research had a small sample size so further research is required. However, important themes are highlighted with the potential to influence clinical practice. All clinicians should receive training to promote cessation at the time of diagnosing respiratory conditions.

    Full Text Available Zaheer Mangera, Kirat Panesar, Himender MakkerRespiratory Medicine, North Middlesex University Hospital, London, UKAbstract: Patients with certain neurological diseases are at increased risk of developing chest infections as well as respiratory failure due to muscular weakness. In particular, patients with certain neuromuscular disorders are at higher risk. These conditions are often associated with sleep disordered breathing. It is important to identify patients at risk of respiratory complications early in the course of their disease, although patients with neuromuscular disorders often present in the acute setting with respiratory involvement. This review of the respiratory complications of neurological disorders, with a particular focus on neuromuscular disorders, explores why this happens and looks at how to recognize, investigate, and manage these patients effectively.Keywords: respiratory failure, respiratory muscle weakness

    2014-07-01

    Full Text Available The systemic vasculitides are multifocal diseases characterized by the presence of blood vessel inflammation in multiple organ systems. Their clinical presentation is variable extending from self-limited illness to critical complications including diffuse alveolar hemorrhage and glomerulonephritis. Alveolar hemorrhage is a lifethreatening manifestation of pulmonary vasculitis that can rapidly progress into acute respiratory failure requiring ventilatory support. We present the case of a 74-year-old patient admitted to the Intensive Care Unit with severe hypoxic respiratory failure and diffuse alveolar infiltrates in chest imaging that was later diagnosed as antineutrophil cytoplasmic antibodies-associated vasculitis. The report highlights the importance of differentiate between alveolar hemorrhage and acute respiratory distress syndrome of other etiology because alveolar hemorrhage is reversible with prompt initiation of treatment.

  11. Severe acute respiratory syndrome in a doctor working at the Prince of Wales Hospital.

    Wong, R S M

    2003-06-01

    Severe acute respiratory syndrome is a new disease that is highly contagious and is spreading in the local community and worldwide. This report is of a hospital medical officer with severe acute respiratory syndrome. He presented with sudden onset of fever, chills, myalgia, headache, and dizziness in early March 2003. He developed progressive respiratory symptoms and bilateral pulmonary infiltrates during the second week of his illness. Blood tests showed lymphopenia, mild thrombocytopenia, and prolonged activated partial thromboplastin time with normal d-dimer level. His chest condition gradually responded to ribavirin and corticosteroids, and serial chest X-ray showed resolving pulmonary infiltrates. The importance of early diagnosis lies in the potential for early treatment, leading to better response.

    PET/CT is playing an important role in disease diagnosis and therapeutic evaluation. But the respiratory motion artifact may bring trouble in diagnosis and therapy. There are many methods to correct the respiratory motion artifact. Respiratory gated PET/CT is applied most extensively of them. Using respiratory gated PET/CT to correct respiratory motion artifact can increase the maximum standardized uptake value of lung lesion obviously, thereby improving the quality of image and accuracy of diagnosis.

    Olechowski, Wiesław; Majorek-Olechowska, Bernadetta

    2010-01-01

    To evaluate the relationships between postnatal passive respiratory compliance (Crs) and development of respiratory disorders during the first 6 month of life in preterm and full-term infants after respiratory insufficiency. The purpose of this study was to investigate whether other relevant neonatal factors, like degree of prematurity, birth weigh, ventilatory conditions, sepsis, and respiratory disease severity affected this relationship. The passive respiratory compliance was measured by the single occlusion technique in 73 preterm infants after respiratory distress syndrome (RDS), 19 full-term infants after congenital pneumonia and 33 healthy full-term infants. Respiratory function measurements were performed by single occlusion technique, during natural sleep, after acute phase of illness, before discharge from neonatal department. Crs was significantly lower in premature newborns newborns who have suffered from a congenital pneumonia (p = 0.0411), than in healthy full-term newborn infants. Premature infants who have undergone sepsis have significantly decreased Crs in relationship with those who did not have this complication (p = 0.0334). Preterm newborns who have suffered pneumonia during treatment of RDS have significantly frequent respiratory problems during the first 6 month of age (p = 0.043). Full-term infants after congenital pneumonia have more but not significantly frequent respiratory problems than healthy term newborns (p = 0.055) in this period. Decreased neonatal Crs wasn't significantly related to respiratory disorders in age of 6 month of life. Prematurity under 36 week of gestational age, low birth weight and suffering from sepsis in premature infants significantly decreased Crs in newborn. Decreased neonatal Crs in premature and full term infants after respiratory insufficiency wasn't significantly related to respiratory disorders during first 6 month of life. This study has showed significantly increase of respiratory problems in this

  16. Impact of respiratory-correlated CT sorting algorithms on the choice of margin definition for free-breathing lung radiotherapy treatments.

    Thengumpallil, Sheeba; Germond, Jean-François; Bourhis, Jean; Bochud, François; Moeckli, Raphaël

    2016-06-01

    To investigate the impact of Toshiba phase- and amplitude-sorting algorithms on the margin strategies for free-breathing lung radiotherapy treatments in the presence of breathing variations. 4D CT of a sphere inside a dynamic thorax phantom was acquired. The 4D CT was reconstructed according to the phase- and amplitude-sorting algorithms. The phantom was moved by reproducing amplitude, frequency, and a mix of amplitude and frequency variations. Artefact analysis was performed for Mid-Ventilation and ITV-based strategies on the images reconstructed by phase- and amplitude-sorting algorithms. The target volume deviation was assessed by comparing the target volume acquired during irregular motion to the volume acquired during regular motion. The amplitude-sorting algorithm shows reduced artefacts for only amplitude variations while the phase-sorting algorithm for only frequency variations. For amplitude and frequency variations, both algorithms perform similarly. Most of the artefacts are blurring and incomplete structures. We found larger artefacts and volume differences for the Mid-Ventilation with respect to the ITV strategy, resulting in a higher relative difference of the surface distortion value which ranges between maximum 14.6% and minimum 4.1%. The amplitude- is superior to the phase-sorting algorithm in the reduction of motion artefacts for amplitude variations while phase-sorting for frequency variations. A proper choice of 4D CT sorting algorithm is important in order to reduce motion artefacts, especially if Mid-Ventilation strategy is used. Copyright © 2016 Elsevier Ireland Ltd.

    Studies of organs in the thorax and abdomen have shown that these organs can move as much as 40 mm due to respiratory motion. Without compensation for this motion during the course of external beam radiation therapy, the dose coverage to target may be compromised. On the other hand, if compensation of this motion is by expansion of the margin around the target, a significant volume of normal tissue may be unnecessarily irradiated. In hypofractionated regimens, the issue of respiratory compensation becomes an important factor and is critical in single-fraction extracranial radiosurgery applications. CyberKnife is an image-guided radiosurgery system that consists of a 6-MV LINAC mounted to a robotic arm coupled through a control loop to a digital diagnostic x-ray imaging system. The robotic arm can point the beam anywhere in space with 6 degrees of freedom, without being constrained to a conventional isocenter. The CyberKnife has been recently upgraded with a real-time respiratory tracking and compensation system called Synchrony. Using external markers in conjunction with diagnostic x-ray images, Synchrony helps guide the robotic arm to move the radiation beam in real time such that the beam always remains aligned with the target. With the aid of Synchrony, the tumor motion can be tracked in three-dimensional space, and the motion-induced dosimetric change to target can be minimized with a limited margin. The working principles, advantages, limitations, and our clinical experience with this new technology will be discussed

    Non-influenzae commensal Haemophilus species of low pathogenicity may be difficult to discriminate from Haemophilus influenzae. We investigated the level of misidentifications in respiratory specimens from cystic fibrosis patients and evaluated the colonisation dynamics of genuine H. influenzae isolates. One hundred and ninety-two presumptive H. influenzae isolates were re-examined by assessment of marker genes sodC and fucK, and isolates with aberrant genotypes were subjected to multilocus sequence typing. Misidentifications (3%) were mainly caused by failure to identify porphyrin-synthesising strains, and only a single strain (0.5%) could be classified as 'non-haemolytic Haemophilus haemolyticus'. Sequential isolates of confirmed H. influenzae isolates from individual patients were typed by pulsed-field gel electrophoresis. Despite the routine prescription of antimicrobial therapy, the majority of H. influenzae isolates were identical with at least one of the strains cultured from the two preceding positive samples from the same patient.

    The Honduran HIV/AIDS Program began to scale up access to HIV therapy in 2002. Up to May 2008, more than 6000 patients received combination antiretroviral therapy (cART). As HIV drug resistance is the major obstacle for effective treatment, the purpose of this study was to assess the prevalence of antiretroviral drug resistance in Honduran HIV-1-infected individuals. We collected samples from 138 individuals (97 adults and 41 children) on cART with virological, immunological or clinical signs of treatment failure. HIV-1 pol sequences were obtained using an in-house method. Resistance mutations were identified according to the 2007 International AIDS Society (IAS)-USA list and predicted susceptibility to cART was scored using the ANRS algorithm. Resistance mutations were detected in 112 patients (81%), 74% in adults and 98% in children. Triple-, dual- and single-class drug resistance was documented in 27%, 43% and 11% of the study subjects, respectively. Multiple logistic regression showed that resistance was independently associated with type of treatment failure [virological failure (odds ratio (OR) = 1) vs. immunological failure (OR = 0.11; 95% confidence interval (CI) 0.030-0.43) vs. clinical failure (OR = 0.037; 95% CI 0.0063-0.22)], route of transmission (OR = 42.8; 95% CI 3.73-491), and years on therapy (OR = 1.81; 95% CI 1.11-2.93). The prevalence of antiretroviral resistance was high in Honduran HIV-infected patients with signs of treatment failure. A majority of study subjects showed dual- or triple-class resistance to nucleoside reverse transcriptase inhibitors, nonnucleoside reverse transcriptase inhibitors and protease inhibitors. Virologically defined treatment failure was a strong predictor of resistance, indicating that viral load testing is needed to correctly identify patients with treatment failure attributable to resistance.

  1. IMPORTANCE OF CYCLOPHOSPHANUM IN THE TREATMENT OF INTERSTITIAL LUNG LESION IN PATIENTS WITH SCLERODERMA SYSTEMATICA (A REVIEW OF LITERATURE

    Olga Aleksandrova Koneva

    2010-01-01

    Full Text Available Interstitial lung diseases (ILD are a common manifestation of scleroderma systematica (SSD that along with pulmonary arterial hypertension remains the leading cause of death in this nosological entity. As of now, cyclophosphanum remains the only immunosuppressant recommended by the European League against Rheumatism for the treatment of ILD in SSD. The paper analyzes the papers providing evidence for the efficacy of cyclophosphanum in ILD in patients with SSD. It also considers the regimens and duration of treatment with cyclophosphanum, ways of evaluating its efficacy and effects on extrapulmonary manifestations of SSD. It is concluded that cyclophosphanum has a positive, predominantly stabilizing, effect on the course of ILD in SSD.

    The benefits of respiratory gating in quantitative PET/CT vary tremendously between individual patients. Respiratory pattern is among many patient-specific characteristics that are thought to play an important role in gating-induced imaging improvements. However, the quantitative relationship between patient-specific characteristics of respiratory pattern and improvements in quantitative accuracy from respiratory-gated PET/CT has not been well established. If such a relationship could be estimated, then patient-specific respiratory patterns could be used to prospectively select appropriate motion compensation during image acquisition on a per-patient basis. This study was undertaken to develop a novel statistical model that predicts quantitative changes in PET/CT imaging due to respiratory gating. Free-breathing static FDG-PET images without gating and respiratory-gated FDG-PET images were collected from 22 lung and liver cancer patients on a PET/CT scanner. PET imaging quality was quantified with peak standardized uptake value (SUVpeak) over lesions of interest. Relative differences in SUVpeak between static and gated PET images were calculated to indicate quantitative imaging changes due to gating. A comprehensive multidimensional extraction of the morphological and statistical characteristics of respiratory patterns was conducted, resulting in 16 features that characterize representative patterns of a single respiratory trace. The six most informative features were subsequently extracted using a stepwise feature selection approach. The multiple-regression model was trained and tested based on a leave-one-subject-out cross-validation. The predicted quantitative improvements in PET imaging achieved an accuracy higher than 90% using a criterion with a dynamic error-tolerance range for SUVpeak values. The results of this study suggest that our prediction framework could be applied to determine which patients would likely benefit from respiratory motion compensation

    To investigate the effects of a respiratory gating and multi field technique on the dose-volume histogram (DVH) in radiotherapy for esophageal cancer. Twenty patients who underwent four-dimensional computed tomography for esophageal cancer were included. We retrospectively created the four treatment plans for each patient, with or without the respiratory gating and multi field technique: No gating-2-field, No gating-4-field, Gating-2-field, and Gating-4-field plans. We compared the DVH parameters of the lung and heart in the No gating-2-field plan with the other three plans.Result In the comparison of the parameters in the No gating-2-field plan, there are significant differences in the Lung V 5Gy , V 20Gy , mean dose with all three plans and the Heart V 25Gy -V 40Gy with Gating-2-field plan, V 35Gy , V 40Gy , mean dose with No Gating-4-field plan and V 30Gy -V 40Gy , and mean dose with Gating-4-field plan. The lung parameters were smaller in the Gating-2-field plan and larger in the No gating-4-field and Gating-4-field plans. The heart parameters were all larger in the No gating-2-field plan. The lung parameters were reduced by the respiratory gating technique and increased by the multi field technique. The heart parameters were reduced by both techniques. It is important to select the optimal technique according to the risk of complications. (author)

  8. Antibiotic treatment interruption of suspected lower respiratory tract infections based on a single procalcitonin measurement at hospital admission--a randomized trial

    Kristoffersen, K B; Søgaard, O S; Wejse, C

    2009-01-01

    Recent studies have suggested that procalcitonin (PCT) is a safe marker for the discrimination between bacterial and viral infection, and that PCT-guided treatment may lead to substantial reductions in antibiotic use. The present objective was to evaluate the effect of a single PCT measurement...... to either PCT-guided treatment or standard treatment. Antibiotic treatment duration in the PCT group was based on the serum PCT value at admission. The cut-off point for recommending antibiotic treatment was PCT > or =0.25 microg/L. Physicians could overrule treatment guidelines. The mean duration...... of hospital stay was 5.9 days in the PCT group vs. 6.7 days in the control group (p 0.22). The mean duration of antibiotic treatment during hospitalization in the PCT group was 5.1 days on average, as compared to 6.8 days in the control group (p 0.007). In a subgroup analysis of chronic obstructive pulmonary...

  9. Biological agents and respiratory infections: Causative mechanisms and practice management.

    Takayanagi, Noboru

    2015-09-01

    Biological agents are increasingly being used to treat patients with immune-mediated inflammatory disease. In Japan, currently approved biological agents for patients with rheumatoid arthritis (RA) include tumor necrosis factor inhibitors, interleukin-6 receptor-blocking monoclonal antibody, and T-cell costimulation inhibitor. Rheumatologists have recognized that safety issues are critical aspects of treatment decisions in RA. Therefore, a wealth of safety data has been gathered from a number of sources, including randomized clinical trials and postmarketing data from large national registries. These data revealed that the most serious adverse events from these drugs are respiratory infections, especially pneumonia, tuberculosis, nontuberculous mycobacteriosis, and Pneumocystis jirovecii pneumonia, and that the most common risk factors associated with these respiratory infections are older age, concomitant corticosteroid use, and underlying respiratory comorbidities. Because of this background, in 2014, the Japanese Respiratory Society published their consensus statement of biological agents and respiratory disorders. This review summarizes this statement and adds recent evidence, especially concerning respiratory infections in RA patients, biological agents and respiratory infections, and practice management of respiratory infections in patients treated with biological agents. To decrease the incidence of infections and reduce mortality, we should know the epidemiology, risk factors, management, and methods of prevention of respiratory infections in patients receiving biological agents.

  13. Ethylene glycol poisoning in three dogs: Importance of early diagnosis and role of hemodialysis as a treatment option.

    Schweighauser, A; Francey, T

    2016-02-01

    Poisoning with ethylene glycol as contained in antifreeze can rapidly lead to irreversible acute renal failure and other organ damage. It carries a grave prognosis unless diagnosed early and adequate treatment is initiated within 8 hours of ingestion. Toxicity of ethylene glycol is related to the production of toxic metabolites by the enzyme alcohol dehydrogenase (ADH), leading to early signs of severe polyuria (PU) and polydipsia (PD), gastritis, ataxia and central nervous depression, followed by progressive dehydration, and ultimately oligoanuric renal failure. In addition to general supportive care, therapeutic interventions must include either antidotes blocking ADH-mediated metabolism or blood purification techniques to remove both the parent compound and the toxic metabolites. The goal of this case report is to describe three cases of acute antifreeze intoxication in dogs, and to discuss treatment options available for this poisoning.

    Maro, S; Zarattin, D; Baron, T; Bourez, S; de la Taille, A; Salomon, L

    2014-09-01

    Bladder catheter can induce a Catheter-Related Bladder Discomfort (CRBD). Antagonist of muscarinic receptor is the gold standard treatment. Clonazepam is an antimuscarinic, muscle relaxing oral drug. The aim of this study is to look for a correlation between the type of surgical procedure and the existence of CRBD and to evaluate the efficiency of clonazepam. One hundred patients needing bladder catheter were evaluated. Sexe, age, BMI, presence of diabetes, surgical procedure and existence of CRBD were noted. Pain was evaluated with analogic visual scale. Timing of pain, need for specific treatment by clonazepam and its efficiency were noted. Correlation between preoperative data, type of surgical procedure, existence of CRBD and efficiency of treatment were evaluated. There were 79 men and 21 women (age: 65.9 years, BMI: 25.4). Twelve patients presented diabetes. Surgical procedure concerned prostate in 39 cases, bladder in 19 cases (tumor resections), endo-urology in 20 cases, upper urinary tract in 12 cases (nephrectomy…) and lower urinary tract in 10 cases (sphincter, sub-uretral tape). Forty patients presented CRBD, (pain 4.5 using VAS). This pain occurred 0.6 days after surgery. No correlation was found between preoperative data and CRBD. Bladder resection and endo-urological procedures were surgical procedures which procured CRBD. Clonazepam was efficient in 30 (75 %) out of 40 patients with CRBD. However, it was less efficient in case of bladder tumor resection. CRBD is frequent and occurred immediately after surgery. Bladder resection and endo-urology were the main surgical procedures which induced CRBD. Clonazepam is efficient in 75 %. Bladder resection is the surgical procedure which is the most refractory to treatment. 5. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

  16. Why the Treatment of Mental Disorders Is an Important Component of HIV Prevention among People Who Inject Drugs

    Buckingham, Elizabeth; Schrage, Ezra; Cournos, Francine

    2013-01-01

    People who inject drugs are more likely to be HIV positive and to have a mental disorder than the general population. We explore how the detection and treatment of mental illness among people who are injecting drugs are essential to primary and secondary prevention of HIV infection in this population. Aside from opioid addiction, few studies have been conducted on the links between mental disorders and injection-drug use. However, independent of the injection-drug use literature, a growing number of studies demonstrate that untreated mental illness, especially depression and alcohol/substance use disorders, is associated with HIV-related risk behaviors, acquiring HIV infection, failure to access HIV care and treatment, failure to adhere to HIV care and treatment, and increased morbidity and mortality from HIV-related diseases and comorbidities. In our review of both the published literature and gray literature we found a dearth of information on models for providing care for both opioid addiction and other mental illnesses regardless of HIV status, particularly in low- and middle-income countries. We therefore make recommendations on how to address the mental health needs of HIV-positive people who inject drugs, which include the provision of opioid substitution therapy and integrated mental health, substance abuse, and HIV services.

    Full Text Available Background: In the treatment of active tuberculosis, therapeutic drug monitoring (TDM is used to optimize dosing that maximizes therapeutic benefit while minimizing toxicity. In Morocco, TDM is not routinely used, yet low levels of anti-TB drugs can be associated with poorer treatment outcomes.Methods: We retrospectively checked our archives for patients with active TB for whom TDM was performed during 2014. Medical records were reviewed to abstract demographic, clinical, radiographic and microbiological data including time until smear and culture conversion. Then, we looked for cases with delay of TB conversion.Results: In total, 24 patients were identified, for whom TDM was performed, they all had low serum drug levels. Among them, 4 patients showed delayed bacteriological conversion.Conclusions: Our study cases are showing the benefit of serum dosage in the follow-up of the patients showing a delay of sputum examination conversion, both direct and culture, during their evolutions. TDM is potentially useful for the treatment of active TB, but is currently underused in Morocco.

The long-term results are compared to the 6-week follow-up outcomes.Patients and methods: Two hundred and seventeen surgery patients were surveyed at 6 weeks, and 206 patients at 12 months after discharge from the trauma surgical general ward. The subjective evaluation of medical treatment outcome was measured 6 weeks and 12 months after discharge with the respective scale from the Cologne Patient Questionnaire. Physician Empathy was assessed with the Consultation and Relational Empathy Measure. The correlation between physician empathy and control variables with the subjective evaluation of medical treatment outcome 12 months after discharge was identified by means of logistic regression analysis under control of sociodemographic and injury-related factors.Results: One hundred and thirty-six patients were included within the logistic regression analysis at the 12-month follow-up. Compared to the 6-week follow-up, the level of subjective evaluation of medical treatment outcome was slightly lower and the association with physician empathy was weaker. Compared to patients who rated the empathy of their surgeon lower than 31 points, patients
