Robinson Summary Reasons for performing study: Although subclinical airway inflammation is thought to be common in horses, there is little information on its prevalence and none on risk factors. Objective: To determine the prevalence and risk factors for an increased number of inflammatory cells and for mucus accumulation in the trachea of pleasure horses. Methods: Horses (n = 266) in stables (n = 21) in Michigan were examined endoscopically, once in winter and once in summer 2004. Visible tracheal mucoid secretions were graded 0,5 and inflammatory cell numbers counted in a tracheal lavage sample. Information collected about each horse included age, gender, presence of cough, percent time indoors and source of roughage. The repeated measures were analysed by generalised estimating equations and linear mixed models. Results: Horses eating hay, especially from round bales, had the most neutrophils, whereas horses feeding from pasture had the fewest. Being female and being outdoors in winter were associated with increased numbers of inflammatory cells. Older horses had fewer macrophages than young horses. More than 70% of horses had >20% neutrophils in tracheal lavage. Twenty percent of horses had a mucus accumulation score >1; 17% had both a mucus score >1 and >20% neutrophils. The significant risk factors for mucus accumulation >1 were age >15 years, feeding on hay as compared to pasture, and being outdoors for more than 80% time in winter. Even though mucus accumulation score >1 was a risk factor for cough, only half of such horses coughed. Cough and mucus accumulation were associated with increased number of neutrophils. Conclusions: In comparison to pasture feeding, hay feeding, particularly from round bales, was associated with an increased number of neutrophils in the airway. Being outdoors in winter was associated with increased numbers of inflammatory cells and with mucus accumulation. Because 70% of horses have >20% neutrophils, this value should not be used as the sole indicator of airway inflammation. Potential relevance: The study reinforces the importance of hay feeding and older age as risk factors for inflammatory airway disease. Horses that do not have ,heaves' may be best kept indoors when winters are cold. [source] The Emergency Department Presentation of Patients with Active Pulmonary TuberculosisACADEMIC EMERGENCY MEDICINE, Issue 9 2000Peter E. Sokolove MD Abstract. Objective: To determine the clinical presentation of emergency department (ED) patients with active pulmonary tuberculosis (TB). Methods: This was a retrospective medical record review of adult patients, identified through infection control records, diagnosed as having active pulmonary TB by sputum culture over a 30-month period at an urban teaching hospital. The ED visits by these patients from one year before to one year after the initial positive sputum culture were categorized as contagious or noncontagious, using defined clinical and radiographic criteria. The medical records of patients with contagious visits to the ED were reviewed to determine chief complaint, presence of TB risk factors and symptoms, and physical examination and chest radiograph findings. Results: During the study period, 44 patients with active pulmonary TB made 66 contagious ED visits. Multiple contagious ED visits were made by 12 patients (27%; 95% CI = 15% to 43%). Chief complaints were pulmonary 33% (95% CI = 22% to 46%), medical but nonpulmonary 41% (95% CI = 29% to 54%), infectious but nonpulmonary 14% (95% CI = 6% to 24%), and traumatic/orthopedic 12% (95% CI = 5% to 22%). At least one TB risk factor was identified in 57 (86%; 95% CI%= 76 to 94%) patient visits and at least one TB symptom in 51 (77%; 95% CI = 65% to 87%) patient visits. Cough was present during only 64% (95% CI = 51% to 75%) of the patient visits and hemoptysis during 8% (95% CI = 3% to 17%). Risk factors and symptoms that, if present, were likely to be detected at triage were foreign birth, homelessness, HIV positivity, hemoptysis, and chest pain. Conclusions: Patients with active pulmonary TB may have multiple ED visits, and often have nonpulmonary complaints. Tuberculosis risk factors and symptoms are usually present in these patients but often missed at ED triage. The diversity of clinical presentations among ED patients with pulmonary TB will likely make it difficult to develop and implement high-yield triage screening criteria. [source] Cough after inhalation of corticosteroids delivered from spacer devices in children with asthmaFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2003Jean-Christophe Dubus Abstract Children using a spacer device rather than another device for delivering inhaled corticosteroids (ICS) has been identified as a risk factor for cough immediately after inhalation. The aim of this study was to point out the different factors influencing the occurrence of such lateral side-effects. We studied this local side-effect in 402 asthmatic children (55.6 ± 34.9 months; 65.6% boys) treated for at least 1 month with beclomethasone dipropionate (n = 331), budesonide (n = 47) or fluticasone propionate (n = 24) delivered from pressurized metered-dose inhalers and small (75.1%) or large volume (24.8%) spacer devices mainly used with face mask (90.7%). A total of 219 patients (54.5%), treated with either high doses of ICS or ICS and long-acting ,2-agonist, were considered as having severe asthma. Cough was reported after each inhalation of corticosteroids in 216 patients (53.7%). Among them, about 30% also complained of cough with ,2-agonists. Despite different propellants and dispersants, all corticosteroids induced cough similarly. Cough was not linked with asthma severity, but was significantly related to therapy duration and use of long-acting ,2-agonist. Type and volume of the spacer device, use of a face mask or mouthpiece were not influencing factors. Cough after inhalation of corticosteroids delivered from spacer devices is a frequent local side-effect in children with asthma. This side effect can greatly alter compliance. A practitioner must be sought at each visit. [source] Influenza-associated hospitalization in urban Thai childrenINFLUENZA AND OTHER RESPIRATORY VIRUSES, Issue 5-6 2007Piyarat Suntarattiwong Background, Studies in North America and Europe have shown that young children are at increased risk of serious complications and hospitalization from influenza infection. In Thailand, however, influenza is commonly considered a mild infection that rarely requires hospitalization. An improved understanding of the burden of serious complications from influenza infection in young children is needed to inform clinical treatment and vaccination guidelines. Methods, We conducted a prospective study of children 0,5 years of age with lower respiratory tract infection or influenza-like illness admitted to a pediatric tertiary-care hospital in Bangkok, Thailand during July 2004 to July 2005. All respiratory specimens were tested for influenza using a rapid antigen test and tissue cell culture. Results, Thirty-nine of 456 (8.6%) hospitalized children had culture-positive influenza. Eighty percent of hospitalized influenza patients had no underlying chronic illnesses. Nineteen (49%) influenza patients required hospital stays of 5 days or more and two patients required mechanical ventilation. Influenza activity demonstrated bimodal seasonal variation with peak activity from August to October and January to April. Cough was present in 38 (97%) cases and fever >38.5°C was significantly associated with influenza. Conclusion, Influenza is an important cause of hospitalization in children <5 years of age in Thailand. Children <5 years should be considered as a target group when establishing clinical guidelines for antiviral treatment and influenza vaccination. [source] Common Health Hazards in French Pilgrims During the Hajj of 2007: A Prospective Cohort StudyJOURNAL OF TRAVEL MEDICINE, Issue 6 2009Philippe Gautret MD Background. The majority of published studies on Hajj-related diseases were based on hospitalized patient cohorts. Methods. A total of 545 Hajj pilgrims from Marseille were enrolled in a prospective epidemiological study to evaluate the incidence of common health hazards. They were administered a questionnaire before traveling addressing demographic factors and health status indicators and a post-travel questionnaire about travel-associated diseases. Results. Respondents had a median age of 61 years and originated mainly from North Africa (81%). A significant proportion of individuals had chronic medical disorders such as walking disability (26%), diabetes mellitus (21%), and hypertension (21%). A total of 462 pilgrims were administered a questionnaire on returning home. A proportion of 59% of travelers presented at least one health problem during the pilgrimage and 44% of the cohort attended a doctor during travel; 3% were hospitalized. Cough was the main complaint among travelers (attack rate of 51%), followed by headache, heat stress, and fever. Few travelers suffered diarrhea and vomiting. Cardiovascular diseases, neurological disorders, trauma, skin and gastrointestinal problems were not frequently observed in our survey, suggesting that their prevalence among the causes of admission to Saudi hospitals reflects a bias of selection. Cough episodes were significantly more frequent in individuals >55 years. We also evidenced that women were more likely to present underlying chronic cardiovascular disorder and diabetes compared to men and that they more frequently suffered from cough episodes associated with fever during the Hajj. Conclusions. Health risks associated with the Hajj in our experience are much more related to crowding conditions than to travel. Our work suggests that the studies performed in Saudi specialized units probably overestimate the part of certain diseases within the spectrum of Hajj-associated diseases. Our results also suggest that old female Hajjes should be considered as a high-risk population and that preventive measures should be reinforced before departing for Saudi Arabia. [source] Review article: respiratory manifestations of gastro-oesophageal reflux diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2008J. P. GALMICHE Summary Background, Respiratory manifestations represent one of the most prevalent and difficult-to-manage extra-oesophageal syndromes of gastro-oesophageal reflux disease. Aims, To review the epidemiology, pathophysiological mechanisms and therapeutic outcomes of reflux-related respiratory disorders. Methods, Search of the literature published in English using PubMed database. Results, There is a discrepancy between the high prevalence of reflux in asthmatics and the limited efficacy of antireflux therapies. Asthma per se may cause reflux. Patients with difficult-to-treat asthma and/or nocturnal symptoms should be screened for reflux. Reflux can induce chronic cough through different mechanisms including micro-aspiration and both local and central reflexes. Cough and reflux may precipitate each other. A meta-analysis found no significant difference between placebo and proton pump inhibitors in the resolution of cough. Encouraging results have been reported, following antireflux surgery in patients selected on the basis of pH-impedance monitoring. Attention has been drawn to obstructive sleep apnoea syndrome. Conclusions, The role of gastro-oesophageal reflux disease in the pathogenesis of miscellaneous respiratory disorders has been discussed for decades and established in asthma and cough. However, no major therapeutic advances have been reported recently. Future trials should concentrate on patient selection and the control of efficacy using recently developed technologies, such as pH-impedance monitoring. [source] Matrix metalloproteinases, IL-8 and glutathione in the prognosis of workers exposed to chlorineALLERGY, Issue 6 2010K. Maghni To cite this article: Maghni K, Malo J-L, L'Archevêque J, Castellanos L, Gautrin D. Matrix metalloproteinases, IL-8 and glutathione in the prognosis of workers exposed to chlorine. Allergy 2010; 65: 722,730. Abstract Background:, Workers exposed to chlorine may be at risk of deterioration in FEV1. Methods:, A prospective study of 72 workers examined over a 5.8 ± 1.9 year period. A sample of induced sputum for cells and mediators was obtained in 69 subjects at baseline (Vb) and in 36 both at Vb and at follow-up (Vf). Results:, Sixty-four workers (89%) experienced at least one accidental inhalation of chlorine in the interval. The mean decrease in FEV1 was 30 ml/year and thus was within normal limits. Among the analysed remodelling markers, the level of the MMP-9-TIMP-1 complex, but not of free MMP-9 and TIMP-1, significantly diminished from Vb to Vf. We found significant correlations between neutrophils, IL-8, MMP-9 and MMP9-TIMP-1 complex at Vb and Vf. While levels of total glutathione, IL-8, MMP9, TIMP-1 and MMP9-TIMP-1 complex were highly correlated with each other at Vb, this was inconstant at Vf. Levels of MMP9-TIMP1 complex and of TIMP1 at Vf were significantly lower in workers reporting chlorine puffs with mild acute respiratory symptoms between visits compared to those who had no, or asymptomatic inhalations (P = 0.03 and 0.02, respectively). The fall in FEV1 from Vb to Vf was significantly correlated with levels of glutathione at Vb. Cough between visits was associated with a decrease in FEV1 (P = 0.06). Conclusion:, Although no accelerated loss in FEV1 was documented in these workers exposed to chlorine, subjects with a greater fall in FEV1 were more likely to report cough and have higher levels of total glutathione at Vb. [source] Symptoms after mould exposure including Stachybotrys chartarum, and comparison with darkroom diseaseALLERGY, Issue 2 2010M. Al-Ahmad To cite this article: Al-Ahmad M, Manno M, Ng V, Ribeiro M, Liss GM, Tarlo SM. Symptoms after mould exposure including Stachybotrys chartarum, and comparison with darkroom disease. Allergy 2010; 65: 245,255. Abstract Background:, Mould-attributed symptoms have included features which overlap with unexplained syndromes such as sick building syndrome. Objectives:, We describe questionnaire and chart review findings in patients following exposure to moulds which include Stachybotrys and compare responses with two control groups. Methods:, Thirty-two patients presented with symptoms attributed to mould exposures. Exposure identification for 25 patients had reported S tachybotrys chartarum as well as other mould (Aspergillus, Penicillium), 88% at work. The remaining seven had professionally visualized or self-reported/photographic exposure evidence only. A chart review was performed and a follow-up with a questionnaire, including questions on current health status, and nonspecific symptoms. Results:, Cough, shortness of breath and chest tightness (at presentation) were reported in 79%, 70% and 64%, respectively, and persisted >6 weeks in 91%. Skin test(s) were positive to fungal extract(s) in 30%. Seventeen returned questionnaires were obtained 3.1 (SD 0.5) years after the initial clinic assessment. Among this subgroup, persisting asthma-like symptoms and symptoms suggestive of sick building syndrome were frequent, and similar to a group previously assessed for darkroom disease among medical radiation technologists. The mould-exposed group more commonly reported they were bothered when walking in a room with carpets, complained of a chemical or metallic taste in their mouth, and had problems in concentration when compared with a control physiotherapist group (P < 0.005). Conclusions:, Although only a minority with health concerns from indoor mould exposure had demonstrable mould-allergy, a significant proportion had asthma-like symptoms. Other symptoms were also common and persistent after the initial implicated exposure. [source] Synergistic interactions between airway afferent nerve subtypes regulating the cough reflex in guinea-pigsTHE JOURNAL OF PHYSIOLOGY, Issue 2 2005Stuart B. Mazzone Cough initiated from the trachea and larynx in anaesthetized guinea-pigs is mediated by capsaicin-insensitive, mechanically sensitive vagal afferent neurones. Tachykinin-containing, capsaicin-sensitive C-fibres also innervate the airways and have been implicated in the cough reflex. Capsaicin-sensitive nerves act centrally and synergistically to modify reflex bronchospasm initiated by airway mechanoreceptor stimulation. The hypothesis that polymodal mechanoreceptors and capsaicin-sensitive afferent nerves similarly interact centrally to regulate coughing was addressed in this study. Cough was evoked from the tracheal mucosa either electrically (16 Hz, 10 s trains, 1,10 V) or by citric acid (0.001,2 m). Neither capsaicin nor bradykinin evoked a cough when applied to the trachea of anaesthetized guinea-pigs, but they substantially reduced the electrical threshold for initiating the cough reflex. The TRPV1 receptor antagonist capsazepine prevented the increased cough sensitivity induced by capsaicin. These effects of topically applied capsaicin and bradykinin were not due to interactions between afferent nerve subtypes within the tracheal wall or a direct effect on the cough receptors, as they were mimicked by nebulizing 1 mg ml,1 bradykinin into the lower airways and by microinjecting 0.5 nmol capsaicin into nucleus of the solitary tract (nTS). Citric acid-induced coughing was also potentiated by inhalation of bradykinin. The effects of tracheal capsaicin challenge on cough were mimicked by microinjecting substance P (0.5,5 nmol) into the nTS and prevented by intracerebroventricular administration (20 nmol h,1) of the neurokinin receptor antagonists CP99994 or SB223412. Tracheal application of these antagonists was without effect. C-fibre activation may thus sensitize the cough reflex via central mechanisms. [source] Latest news and product developmentsPRESCRIBER, Issue 8 2008Article first published online: 12 MAY 200 Glargine preferred to lispro as type 2 add-on Basal insulin glargine (Lantus) and insulin lispro (Humalog) at mealtimes improved glycaemic control equally well in patients with type 2 diabetes poorly controlled by oral agents, but patient satisfaction was greater with basal insulin (Lancet 2008;371:1073-84). The 44-week APOLLO trial, funded by Sanofi Aventis, was a nonblinded randomised comparison of basal and prandial insulin regimens added to oral treatment in 418 patients. It found similar reductions in HbA1C (,1.7 vs ,1.9 per cent respectively). Fasting and nocturnal glucose levels were lower with insulin glargine and postprandial levels were lower with insulin lispro. The basal regimen was associated with fewer hypoglycaemic events (5.2 vs 24 per patient per year), less weight gain (3.01 vs 3.54kg) and greater improvement in patient satisfaction scores. Treating hypertension cuts mortality in over-80s Treating hypertension in the over-80s reduces all-cause mortality by 21 per cent, the HYVET study has shown (N Engl J Med online: 31 March 2008; doi: 10.1056/NEJMoa 0801369). Compared with placebo, treatment with indapamide alone or with perindopril for an average of 1.8 years also reduced the incidence of fatal stroke by 39 per cent, cardiovascular death by 23 per cent and heart failure by 64 per cent. The incidence of stroke was reduced by 30 per cent but this was of borderline statistical significance. Fewer serious adverse events were reported with treatment than with placebo. New work for NICE The DoH has announced the 18th work programme for NICE. Seven public health interventions include preventing skin cancer, smoking by children and excess weight gain during pregnancy. Public health guidance will include the provision of contraceptive services for socially disadvantaged young people. Two new clinical guidelines are sedation in young people and management of fractured neck of femur. New technology appraisals may include eight therapies for cancer, two new monoclonal antibodies for psoriasis and rheumatoid arthritis, an oral retinoid for severe chronic hand eczema and methylnaltrexone for opioid-induced bowel dysfunction. Combinations no better against CV disease Taking ezetimibe and simvastatin (Inegy) does not appear to slow the progression of atherosclerosis more than high-dose simvastatin alone, say researchers from The Netherlands (N Engl J Med 2008;358: 1431-43). In patients with hypercholesterolaemia, there was no difference in regression or progression of atherosclerosis after two years' treatment with simvastatin 80mg per day alone or combined with ezetimibe 10mg per day. Adverse event rates were similar. In patients with vascular disease or high-risk diabetes, there was no difference between the ACE inhibitor ramipril 10mg per day or the ARB telmisartan (Micardis) 80mg per day as monotherapy, or their combination, in the risk of a composite outcome of cardiovascular death, MI, stroke and admission for heart failure (N Engl J Med 2008;358:1547-59). Combined treatment was associated with higher risks of hypotensive symptoms, syncope and renal dysfunction. Twice-daily celecoxib increases CV risk Taking celecoxib (Celebrex) twice daily carries a higher risk of cardiovascular events than the same total dose taken once daily, a metaanalysis suggests (Circulation 2008; doi: 10.1161/ CIRCULATIONAHA.108. 764530). The analysis of six placebo-controlled trials involving a total of 7950 patients taking celecoxib for indications other than rheumatoid arthritis found that the combined risk of cardiovascular death, myocardial infarction, stroke, heart failure or thromboembolic event increased with dose over the range 400-800mg per day. The risk was significantly greater with 200mg twice daily (HR 1.8) than 400mg once daily (HR 1.1). Patients at greatest baseline risk were at disproportionately increased risk from celecoxib. Long-term etanercept effective in AS An open-label study suggests that etanercept (Enbrel) remains effective in the treatment of ankylosing spondylitis in the long term (Ann Rheum Dis 2008;67:346-52). Of 257 patients who completed six months' treatment with etanercept and who entered the nonblinded extension study, 126 completed a total of 168-192 weeks' treatment. The commonest adverse events were injection-site reactions (22 per cent), headache (20 per cent) and diarrhoea (17.5 per cent). The annual rate of serious infections was 0.02 per person. Response and partial remission rates after 192 weeks were similar to those reported after 96 weeks. Metformin reduces risk Metformin reduces the risk of developing diabetes in individuals at increased risk, a meta-analysis suggests (Am J Med 2008;121:149-57.e2). The study included 31 mostly small, randomised, controlled trials involving a total of 4570 participants and lasting at least eight weeks (8267 patient-years of treatment). Metformin was associated with reductions in body mass (,5.3 per cent), fasting glucose (,4.5 per cent) and insulin resistance (,22.6 per cent); lipid profiles also improved. The odds of developing diabetes were reduced by 40 per cent,an absolute risk reduction of 6 per cent over 1.8 years. MHRA clarifies cough and colds advice Press reports mistakenly suggested that the MHRA had banned some cough and cold remedies when it issued new guidance on treating young children, the MHRA says. The Agency's advice followed a review of over-thecounter cough and cold medicines for children by the Commission on Human Medicines. Children under two are at increased risk of adverse reactions and should no longer be treated with products containing antihistamine (chlorphenamine, brompheniramine, diphenhydramine), antitussives (dextromethorphan, pholcodine), expectorants (guaifenesin, ipecacuanha) and decongestants (phenylephrine, pseudoephedrine, ephedrine, oxymetazoline and xylometazoline). The MHRA said these products, which are classified as general sale medicines, should be removed from open shelves until available in new packaging that complies with the advice. They may still be supplied by a pharmacist for the treatment of older children. Coughs and colds should be treated with paracetamol or ibuprofen for fever, a simple glycerol, honey or lemon syrup for cough, and vapour rubs and inhalant decongestants for stuffy nose. Saline drops can be used to thin and clear nasal secretions in young babies. Parents are being urged not to use more than one product at a time to avoid inadvertently administering the same constituent drug twice. Perindopril brand switch Servier Laboratories is replacing its current formulations of perindopril (Coversyl, Coversyl Plus) with a new product that is not bioequivalent. The current Coversyl brand contains perindopril erbumine (also known as tert -butylamine). The new formulation contains perindopril arginine; it will be distinguished by new brand names (Coversyl Arginine, Coversyl Arginine Plus) and new packaging. Coversyl 2, 4 and 8mg tablets are equivalent to Coversyl Arginine 2.5, 5 and 10mg. Servier says the change is part of the simplification and harmonisation of global manufacturing; the arginine salt is already used in other countries and offers greater stability and a longer shelf-life. Both Coversyl and Coversyl Arginine will be in the supply chain for the next few weeks. Generic perindopril will continue to be the erbumine salt and prescriptions for generic perindopril are not affected. New from NICE Diabetes in pregnancy: management of diabetes and its complications from preconception to the postnatal period. Clinical Guidance No. 63, March 2008 This clinical guideline focuses on additional aspects of care for women with gestational diabetes (88 per cent of cases) or pre-existing diabetes (of which about 40 per cent is type 2 diabetes) and their babies. To date, insulin aspart (NovoRapid) is the only drug in the guideline specifically licensed for use in pregnancy and NICE advises obtaining informed consent to implement its recommendations for using other insulins and oral hypoglycaemic agents. As with other guidelines, NICE begins by stressing the importance of patient-centred care and involving women in decisions about their treatment. The guideline is divided into six sections, dealing with consecutive periods of pregnancy. Preconceptual planning should include empowering women to help them reduce risks, optimising glycaemic control (after retinal assessment) and increasing monitoring intensity, and providing information about the effects of pregnancy on diabetes. Metformin may be recommended as an adjunct or alternative to insulin, but other oral hypoglycaemic agents should be replaced with insulin, although glibenclamide is an option during pregnancy. Isophane insulin is the preferred long-acting insulin; lispro (Humalog) and aspart are considered safe to use. ACE inhibitors and angiotensin-II receptor blockers should be replaced with other antihypertensive agents and statins should be discontinued. Recommendations for screening and treatment of gestational diabetes build on previous guidance (CG62). Drug treatment will be needed by 10-20 per cent , this includes insulin (soluble, aspart or lispro) and/or metformin or glibenclamide, tailored to individual need. Antenatal care includes optimising glycaemic control. Insulin lispro or aspart should be considered in preference to soluble insulin. If glycaemic control cannot be achieved with insulin injections, an insulin pump may be indicated. The guideline includes a timetable for appointments and the care that should offered after each interval. Recommendations for intrapartum care, which supplement those in CG55, include frequent monitoring of blood glucose. Neonatal care includes recommendations for monitoring and screening the infant and the management of hypoglycaemia. Postnatal care (supplementing CG37) involves adjusting maternal treatment to avoid hypoglycaemia and recommendations for returning to community care. Metformin and glibenclamide are the only oral agents suitable for breastfeeding women. Women with gestational diabetes need advice about glycaemic control and planning for future pregnancies. Lifestyle advice and measurement of annual fasting plasma glucose should be offered. Inhaled corticosteroids for the treatment of chronic asthma in adults and in children aged 12 years and over. Technology Appraisal No. 138, March 2008 The latest technology appraisal of asthma treatments covers inhaled steroids for adults and children over 12 with chronic asthma. It makes only two recommendations. First, the cheapest appropriate option is recommended. Second, when a steroid and a long-acting beta2-agonist are indicated, the decision to prescribe a combined inhaler or separate devices should take into account therapeutic need and likely adherence. Combined inhalers are currently less expensive than separate devices, though they may not remain so. When a combined inhaler is chosen it should be the cheapest. NICE concludes that, at equivalent doses, there is little difference in the effectiveness or adverse event profile of the available steroids or the fixed-dose combinations. According to specialist advice, choosing the best device for an individual remains the overriding concern. Continuous positive airway pressure for the treatment of obstructive sleep apnoea/hypopnoea syndrome. Technology Appraisal No. 139, March 2008 NICE recommends continuous positive airway pressure (CPAP) for adults with moderate or severe obstructive sleep apnoea, and for those with a milder disorder if quality of life and functioning are impaired and alternative strategies such as lifestyle change have failed. Diagnosis and treatment is the responsibility of a specialist team. A CPAP device costs £250-£550 and lasts for seven years. Copyright © 2008 Wiley Interface Ltd [source] Quality control in urodynamics: a review of urodynamic traces from one centreBJU INTERNATIONAL, Issue 3 2003J. Sullivan OBJECTIVE To investigate quality control in our unit and to enable other units to compare their results, as experience from central reviews of urodynamic traces for multicentre trials has suggested that poor quality control is common. PATIENTS AND METHODS All consecutive male urodynamic tests conducted over 1 year were reviewed. A list of criteria to assess the quality of the records was devised, based upon International Continence Society guidelines on ,good urodynamic practice', and on other sources. Eligible traces were analysed for aspects of quality control, e.g. baseline pressures and coughs to test pressure transmission. The data were analysed to establish how often quality criteria were met, and identify areas for improvement. RESULTS In 100 eligible traces, the baseline detrusor pressure was 0,10 cmH2O in 86, and , 5 to +10 cmH2O in 94%. Baseline intravesical and abdominal pressure were 30,50 cmH2O in 68% and 73% of cases, respectively. Coughs were present before filling in 94%, during filling in 95%, before voiding in 72% and after voiding in 87% of cases. The cough-test frequency was sufficient in 30% of traces. In 11 the intravesical pressure line fell out during voiding. CONCLUSION Most of the traces assessed met the quality criteria defined, but significant defects were not uncommon. Some of the problems identified suggest areas of urodynamic technique which should be studied in more detail. We intend to modify our quality control practices, and hope to show an improvement on re-audit. We hope that other urodynamic departments will be encouraged to review their practice, and we aim to improve our results. [source] P56 Occupational protein contact dermatitis from shiitake mushroomsCONTACT DERMATITIS, Issue 3 2004Renata Kaminska Case report:, A 54-year-old woman, with no family or personal history of atopy, developed skin symptoms and cough after she had been cultivating shiitake mushrooms for 12 months. The patient reported dermatitis on the backs of her hands, fingers and on her wrists, after 1 or 2 days of being in contact with shiitake mushrooms. The skin lesions and cough disappeared entirely during the holidays. Result: Prick tests to common inhalant allergens, molds and flours were negative, with the exception of D. farinae (3 mm). The prick-to-prick test was positive for shiitake gill (3 mm), shiitake stalk (3 mm) and dry shiitake (8 mm ps). The histamine wheal was 5,7 mm. Control prick tests with shiitake on 5 nonexposed subjects were negative. An open test was performed with shiitake on the flexor side of the upper arm. Within 20 minutes a positive reaction appeared comprising two wheals and flare reactions. Patch test with shiitake gave a strong toxic reaction in 2 days, which continued to diminish on days 3 and 4. Conclusion: Contact urticaria is the clinical skin symptom of immediate allergy, but repeated exposure may lead to protein contact dermatitis. However, our patient has not had urticaria symptoms from shiitake, although the prick-to-prick and open tests were positive. To our knowledge, this is the first report of protein contact dermatitis from shiitake in a patient with a positive immediate skin reaction and negative patch test result. [source] Efficacy and tolerance of intranasal insulin administered during 4 months in severely hyperglycaemic Type 2 diabetic patients with oral drug failure: a cross-over studyDIABETIC MEDICINE, Issue 8 2001D. Lalej-Bennis Abstract Aims We have evaluated the local tolerance and the metabolic efficacy of a lyophilized nasal insulin preparation in 10 severely hyperglycaemic Type 2 diabetic patients. Methods The study included two 4-month randomized periods: (A) three preprandial doses of nasal insulin secondarily combined with one evening subcutaneous NPH if the desired glycaemic control was not achieved; (B) two NPH injections daily. We assessed: (i) diabetes control on monthly HbA1c levels and occurrence of hypoglycaemic events; (ii) local tolerance on clinical symptoms, rhinoscopy, nasal muco-ciliary clearance and nasal biopsies; (iii) insulin absorption at months 0 and 4. Results One patient was withdrawn because of cough and dizziness after each nasal application. HbA1c was not significantly different at month 4 (9.4 ± 0.5% vs. 8.8 ± 0.2%, A vs. B). Blood glucose control remained only fair in the majority of our patients. Nasal insulin was able to replace the daytime fraction of the subcutaneous insulin with a 18% efficacy. Side-effects included transient nasal hyperactivity (pruritis, sneezing and rhinorrhoea) and chronic persistence of nasal crusts. Plasma insulin profiles were not significantly different between months 0 and 4. Conclusions The utilization of nasal insulin (with or without NPH) was associated with similar diabetes control compared with NPH twice daily. Nasal insulin alone was able to achieve an adequate glycaemic control in three of the 10 patients. Diabet.

The presence of polymicrobial infection in a renal transplant recipient is documented in the literature, but has rarely been diagnosed on cytology. We report a case of concomitant pulmonary cryptococcosis, aspergillosis, and tuberculosis in a renal transplant recipient diagnosed on FNAC. A 50-year-old renal transplant recipient, asymptomatic for 3 year, presented with intermittent low-grade fever associated with cough, expectoration, and a newly developed cavitatory lesion in the left lung on chest X-ray. Computed tomography-guided FNAC performed on the lung lesion showed fungal profiles with septate hyphae and acute-angled branching consistent with morphology of Aspergillus. In addition, numerous yeast forms of cryptococcus and a few acid-fast mycobacterial tubercle bacilli were seen. Guided FNAC is a useful and reliable technique for the diagnosis of pulmonary infection. One should always keep in mind the possibility of polymicrobial infections especially inimmunocompromised patients. Diagn. Cytopathol. 2010. © 2009 Wiley-Liss, Inc. [source] PEUTZ,JEGHERS POLYPOSIS WITH BLEEDING FROM POLYPS OF THE SIGMOID COLON SUCCESSFULLY TREATED BY LAPAROSCOPIC SURGERYDIGESTIVE ENDOSCOPY, Issue 1 2003Kazuhiro Yada We report a case of colonic bleeding complicating congestive heart failure in a patient with Peutz,Jeghers (P,J) polyposis successfully treated by laparoscopic surgery. A 49-year-old woman was admitted for severe cough and edema of the extremities. Chest X-ray revealed bilateral pleural effusion and cardiomegaly. Her cardiac function was within normal limits, but anemia and severe hypoproteinemia were observed. During the treatment, anal bleeding was observed. Endoscopic and radiographic examinations revealed hundreds of polyps from the duodenum to the rectum. 99mTc-diethylene triamine penta-acetic acid human serum albumin scintigraphy showed radiotracer collected in the sigmoid colon, the area having the most polyps. After some intestinal polypoid lesions were resected endoscopically, laparoscopy-assisted sigmoid colectomy and cecectomy were performed. In the postoperative course, she complained less about abdominal pain and her first flatus occurred on the third postoperative day. She recovered uneventfully. The anemia, hypoproteinemia, and congestive heart failure resolved and gastrointestinal bleeding has not been seen. It was thought that protein loss and hemorrhage due to the P,J polyposis caused congestive heart failure. When congestive heart failure is accompanied by gastrointestinal hemorrhage, it is important to consider hypoproteinemia due to gastrointestinal polyposis, such as that characterizing P,J syndrome. Laparoscopic surgery was very useful for the treatment of colonic bleeding. [source] Outcomes after laparoscopic Nissen fundoplication are not influenced by the pattern of refluxDISEASES OF THE ESOPHAGUS, Issue 2 2008A. T. Meneghetti SUMMARY., The purpose of this study was to compare the outcomes of patients with different types of gastroesophageal reflux disease (upright, supine, or bipositional) after laparoscopic Nissen fundoplication and determine if patients with upright reflux have worse outcomes. Two hundred and twenty-five patients with reflux confirmed by 24-h pH monitoring were divided into three groups based on the type of reflux present. Patients were questioned pre- and post-fundoplication regarding the presence and duration of symptoms (heartburn, regurgitation, dysphagia, cough and chest pain). Symptoms were scored using a 5-point scale, ranging from 0 (no symptom) to 4 (disabling symptom). Esophageal manometry and pH results were also compared. There was no statistically significant difference in lower esophageal sphincter length, pressure or function between the three groups. There was no significant difference in any of the postoperative symptom categories between the three groups. The type of reflux identified preoperatively does not have an adverse effect on postoperative outcomes after Nissen fundoplication and should not discourage physicians from offering antireflux surgery to patients with upright reflux. [source] Comparison of the effect of a cornstarch thickened formula and strengthened regular formula on regurgitation, gastric emptying and weight gain in infantile regurgitationDISEASES OF THE ESOPHAGUS, Issue 2 2007H.-C. Chao SUMMARY., The purpose of this study was to evaluate the efficacy of a specially selected cornstarch-supplemented formula on clinical symptoms, gastric emptying and weight gain in infants with regurgitation. We performed a prospective randomised trial evaluating the therapeutic efficacy of two different formula feedings (cornstarch-thickened formula, group A; 25% strengthened formula, group B) in 81 young infants with regurgitation/vomiting , 3 times/day. A Tc-99 m milk scintigraphy was performed at inclusion and after 2 months to quantify gastric emptying time; all studied infants underwent a 2-month period of clinical follow-up evaluating regurgitation and body weight gain. At inclusion, group A and B had a similar age and weight. After the 2-month period of intervention, regurgitation and vomiting had both greater decrease (both P < 0.001 at 1 and 2 months) in group A (from a score of 4.19 ± 1.71 to 0.93 ± 0.42) than in group B (from a score of 4.15 ± 1.68 to 2.89 ± 1.16). Non-regurgitation symptoms (irritability, cough, choking, night-waking) decreased (P = 0.045 at 1 month and 0.017 at 2 months) in group A (from a score of 18 at baseline to 3 after 8 weeks) as compared to group B (from a score of 18 at baseline to 11 after 8 weeks). Weight increased more in group A (29.1 ± 3.9 g/day over 8 weeks) versus group B (23.6 ± 3.5 g/day over 8 weeks) (P < 0.01 at 1 and 2 months) Gastric emptying improved significantly in group A as compared with group B (all P < 0.001 for T1/2, and residual volume at 60 and 90 min). Ingested feeding volume was significantly larger in the group receiving cornstarch-thickened formula, both at 4 weeks (109.4 ± 24.5 vs. 98.5 ± 23.6 mL/meal) (P: 0.042) and at 8 weeks (137.6 ± 27.9 vs. 115.7 ± 26.5 mL/meal) (P < 0.001). Cornstarch-thickened formula feeding decreases the frequency of regurgitation/vomiting, provides better body weight gain and has an accelerated gastric emptying in comparison to a 25% strengthened regular formula in infants with regurgitation. [source] Distal esophagitis in patients with mustard-gas induced chronic coughDISEASES OF THE ESOPHAGUS, Issue 4 2006M. Ghanei SUMMARY., Although confounded by some factors such as medications or surgical complications, the relationship between esophageal pathology and pulmonary disorders has been the subject of many studies. The present study sought to investigate the said relationship in patients inflicted by respiratory disorders induced by mustard gas (MG). A case group of patients complaining of respiratory complications and chronic coughs following MG exposure, and a control group of patients with chronic coughs but without a history of MG exposure were studied. All the case and control subjects had symptoms of gastro-esophageal reflux disease. Chest high resolution tomography (HRCT) was performed to evaluate the existence of pulmonary disorders. Endoscopy and histological studies were carried out to determine the severity of esophagitis in both groups presenting with gastroesophageal reflux. Ninety male patients, who had met our criteria, along with 40 male control cases underwent the diagnostic procedures. The frequency of endoscopic esophagitis findings in the chemically exposed group was significantly higher than that in the control group (70.0%vs. 42.5%). A pathological evaluation revealed that the frequency of esophagitis in the cases was more than that in the controls (32.3%vs. 14.2%). Chest HRCT evaluation demonstrated that half the case group had more than 25% air trapping in expiratory films, mostly compatible with bronchiolitis obliterans (BO). In addition, they were suffering from asthma, chronic bronchitis and bronchiectasis. Bronchiolitis obliterans, along with other lung disorders, can be considered as contributors in the pathogenesis of esophagitis in MG exposed patients. [source] A System for Grouping Presenting Complaints: The Pediatric Emergency Reason for Visit ClustersACADEMIC EMERGENCY MEDICINE, Issue 8 2005MSCE, Marc H. Gorelick MD Abstract Objectives: To develop a set of chief complaint groupings for pediatric emergency department (ED) visits that is comprehensive, parsimonious, clinically sensible, and evidence-based. Methods: Investigators derived candidate chief complaint clusters and ranked them a priori into three perceived severity categories. Pediatric visits were extracted from the National Hospital Ambulatory Medical Care Survey (NHAMCS); data for years 1998 and 2000 (n= 13,186) were used for derivation and data for year 1999 (n= 5,365) were used for validation. Visits were assigned to clusters based on the recorded complaints; clusters were combined to ensure adequate numbers for analysis (minimum n= 20), and the clusters were reviewed for clinical sensibility. Resource utilization was categorized in three levels: routine (examination only), ED treatment (tests or therapy in the ED but not admitted), and admission. Area under the receiver-operating characteristic (ROC) curve (AUC) was used to demonstrate the discriminative ability of the clusters in predicting resource use. Results: There were 463 unique complaints in the derivation database; 95 (20%) had a single associated visit. Fifty-two clusters were generated; only 2.4% of complaints were classified as other. The eight most common clusters encompassed 52% of the visits. The top five were fever (11%), extremity pain/injury, vomiting, cough, and trauma (unspecified). Complaint clusters were associated with actual resource utilization: for routine care, the AUC was 0.73 (0.74 in the validation set), and for admission, the AUC was 0.77 (0.74 in the validation set). Both resource utilization and triage classification increased with increased expert severity ranking (test for trend, p < 0.001). Conclusions: The proposed Pediatric Emergency Reason for Visit Cluster (PERC) system is a comprehensive yet parsimonious, clinically sensible means of categorizing pediatric ED complaints. The PERC system's association with measures of acuity and resource utilization makes it a potentially useful tool in epidemiologic and health services research. [source] Has the Clinical Presentation and Clinician's Index of Suspicion of Cardiac Tamponade Changed Over the Past Decade?ECHOCARDIOGRAPHY, Issue 3 2008Sachin Gandhi M.D. It remains unclear whether advances in the understanding of the pathophysiology and improvements in cardiovascular imaging over the years have impacted the clinician's recognition of cardiac tamponade (CT). We sought to evaluate signs and symptoms of CT in a present-day population and compare it to a similar group from a decade prior. We performed a retrospective analysis of two cohorts of patients presenting to a tertiary hospital with CT, all of whom underwent pericardial drainage (PD). Group 1 (Gp1) included subjects presenting from 1988 to 1991 and Group 2 (Gp2) included subjects from 2002 to 2005. Fifty-five patients comprised each group, with an average age of 55 years. Seventy-one percent of patients in Gp1 had identifiable cardiovascular symptoms 1 week prior to presentation, compared to 33% in Gp2. Dyspnea was the most common symptom in both groups, and was less frequent in Gp2. Compared with Gp1, chest pain, cough, and lethargy were also less frequent in Gp2. One day prior to PD, tachypnea and pulsus paradoxus were detected more frequently in Gp1 compared to Gp2. Large, circumferential pericardial effusions were the most frequent echocardiographic findings in both groups and the most common etiology of CT was malignancy in Gp1and postoperative bleeding in Gp2. Thus, the recognition of symptoms and physical signs in patients presenting with CT has changed over the past decade, as has etiology of pericardial effusions. However, the diagnosis of CT still remains delayed, and the present data emphasize the need for a heightened index of suspicion for recognizing this hemodynamically-important process. [source] Rupture of a Right Sinus of Valsalva Aneurysm into the Right Ventricle During Vaginal Delivery: A Case ReportECHOCARDIOGRAPHY, Issue 10 2005F.E.S.C., Josip Vincelj M.D., Ph.D. A case is reported of a right sinus of Valsalva aneurysm rupture into the right ventricle during vaginal delivery in a 34-year-old healthy woman in her third pregnancy. Pregnancy was carried to term and a healthy baby was delivered vaginally. On day 7 following vaginal delivery she was admitted to hospital for dyspnea and cough, with clinical signs of severe heart failure. The diagnosis of the right sinus of Valsalva aneurysm rupture into the right ventricle was established by transthoracic and transesophageal echocardiography. Clinical recognition and early echocardiographic diagnosis followed by immediate surgical repair proved lifesaving in our patient.

Rojman Summary A 12-year-old Paint-Arab mare was admitted for evaluation of a penetrating chest laceration at the thoracic inlet. The left brachiocephalic muscle was transected and the recurrent laryngeal nerve was traumatised. Subsequent to the injury, the horse developed Horner's syndrome on the left side of the neck and face, Grade IV left laryngeal hemiplegia, dysphagia, cough and subcutaneous emphysema. The defect was closed in multiple layers. Antimicrobial and antiinflammatory therapy was instituted along with local wound care. The mare remained bright and responsive and the wound healed normally. The mare showed no signs of respiratory distress. Dysphagia and ptosis persisted at 30 days post trauma. [source] Airway inflammation in Michigan pleasure horses: prevalence and risk factorsEQUINE VETERINARY JOURNAL, Issue 4 2006N. E. Robinson Summary Reasons for performing study: Although subclinical airway inflammation is thought to be common in horses, there is little information on its prevalence and none on risk factors. Objective: To determine the prevalence and risk factors for an increased number of inflammatory cells and for mucus accumulation in the trachea of pleasure horses. Methods: Horses (n = 266) in stables (n = 21) in Michigan were examined endoscopically, once in winter and once in summer 2004. Visible tracheal mucoid secretions were graded 0,5 and inflammatory cell numbers counted in a tracheal lavage sample. Information collected about each horse included age, gender, presence of cough, percent time indoors and source of roughage. The repeated measures were analysed by generalised estimating equations and linear mixed models. Results: Horses eating hay, especially from round bales, had the most neutrophils, whereas horses feeding from pasture had the fewest. Being female and being outdoors in winter were associated with increased numbers of inflammatory cells. Older horses had fewer macrophages than young horses. More than 70% of horses had >20% neutrophils in tracheal lavage. Twenty percent of horses had a mucus accumulation score >1; 17% had both a mucus score >1 and >20% neutrophils. The significant risk factors for mucus accumulation >1 were age >15 years, feeding on hay as compared to pasture, and being outdoors for more than 80% time in winter. Even though mucus accumulation score >1 was a risk factor for cough, only half of such horses coughed. Cough and mucus accumulation were associated with increased number of neutrophils. Conclusions: In comparison to pasture feeding, hay feeding, particularly from round bales, was associated with an increased number of neutrophils in the airway. Being outdoors in winter was associated with increased numbers of inflammatory cells and with mucus accumulation. Because 70% of horses have >20% neutrophils, this value should not be used as the sole indicator of airway inflammation. Potential relevance: The study reinforces the importance of hay feeding and older age as risk factors for inflammatory airway disease. Horses that do not have ,heaves' may be best kept indoors when winters are cold. [source] Health-related quality of life, symptom distress and sense of coherence in adult survivors of allogeneic stem-cell transplantationEUROPEAN JOURNAL OF CANCER CARE, Issue 2 2001L. Edman This is the first Swedish study to evaluate the health-related quality of life and sense of coherence in adult survivors of allogeneic, haematopoietic stem cell transplantation (HSCT). Twenty-five recipients completed three questionnaires 2,4 years after the transplantation. The questionnaires used were the Sickness Impact Profile (SIP), the Symptom Frequency Intensity and Distress (SFID-BMT) scale and the Sense of Coherence (SOC) scale measuring subjective functional status, symptom distress and coping ability. Impairments in functional status were found, as compared with a population norm. The most common impairments were found in the areas of social interaction and sleep and rest. Eye problems, dry mouth, cough, sexual problems, tiredness, anxiety and changes of taste were symptoms reported by more than half of the patients. Despite impaired functioning and a high incidence of symptoms, the general health was described as quite good or excellent by 80% (n = 20) of the patients. The majority (20/22) had also been able to return to work or to attend school. No difference in the sense of coherence was seen, as compared with the population norm. Functional impairments were significantly correlated to a lower degree of sense of coherence. [source] Characterization of Bordetella pertussis clinical isolates that do not express the tracheal colonization factorFEMS IMMUNOLOGY & MEDICAL MICROBIOLOGY, Issue 1 2007Marjolein Van Gent Abstract Bordetella pertussis, the causative agent of whooping cough, has remained endemic and there is a resurgence in some countries despite vaccination. Bordetella pertussis produces a wide range of virulence factors which are assumed to play an important role in infection and transmission, including tracheal colonization factor (TcfA). Here we show that clinical isolates belonging to distinct lineages may lose their ability to produce TcfA. Irreversible and reversible loss occurred, respectively, by recombination between repeats leading to deletion of the tcfA gene and by mutations in a polymorphic G-track. These phenomena may reflect adaptation to distinct niches. [source] Cough after inhalation of corticosteroids delivered from spacer devices in children with asthmaFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2003Jean-Christophe Dubus Abstract Children using a spacer device rather than another device for delivering inhaled corticosteroids (ICS) has been identified as a risk factor for cough immediately after inhalation. The aim of this study was to point out the different factors influencing the occurrence of such lateral side-effects. We studied this local side-effect in 402 asthmatic children (55.6 ± 34.9 months; 65.6% boys) treated for at least 1 month with beclomethasone dipropionate (n = 331), budesonide (n = 47) or fluticasone propionate (n = 24) delivered from pressurized metered-dose inhalers and small (75.1%) or large volume (24.8%) spacer devices mainly used with face mask (90.7%). A total of 219 patients (54.5%), treated with either high doses of ICS or ICS and long-acting ,2-agonist, were considered as having severe asthma. Cough was reported after each inhalation of corticosteroids in 216 patients (53.7%). Among them, about 30% also complained of cough with ,2-agonists. Despite different propellants and dispersants, all corticosteroids induced cough similarly. Cough was not linked with asthma severity, but was significantly related to therapy duration and use of long-acting ,2-agonist. Type and volume of the spacer device, use of a face mask or mouthpiece were not influencing factors. Cough after inhalation of corticosteroids delivered from spacer devices is a frequent local side-effect in children with asthma. This side effect can greatly alter compliance. A practitioner must be sought at each visit. [source] Predictive values for aspiration after endoscopic laser resections of malignant tumors of the hypopharynx and larynxHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2004Manuel Bernal-Sprekelsen MD Abstract Background. CO2 -laser surgery is a relatively new treatment for selected carcinomas of the upper aerodigestive tract. The purpose of our study was to evaluate prospectively the functional results for swallowing after C02 -laser resections. Methods. The sample was composed of 210 consecutive patients with malignancies of the larynx and hypopharynx treated with CO2 laser between February 1998 and January 2002. Endoscopic resections included all T1 and T2 tumors and selected T3 and T4 tumors. T1 glottic tumors were not included in the analysis. We assessed the need for a feeding tube and the period the tube remained in place, aspiration pneumonia, tracheotomy secondary to aspiration, the need for a permanent or temporary gastrostomy, and total laryngectomy secondary to aspiration. Results. The nasogastric feeding tube was used in 23.2% of small tumors (2.5 ± 8.04 days) and in 63% of locally advanced tumors (13.95 ± 22.55 days). Frequency and period of storage of the feeding tube were higher in locally advanced tumors (p = .0001). Twelve patients (5.7%) had postoperative pneumonia and 59 (28.1%) had temporary postoperative cough during oral intake. Aspiration symptoms correlated with location (p = .001) and locally advanced tumors (p = .016). Eight patients (3.8%) needed a postoperative tracheotomy for severe swallowing difficulties; six (2.9%) of them were definitive and two (0.95%) temporary. Thirteen gastrostomies (6.2%) were performed to avoid severe aspirations; five of them were definitive. The need for gastrostomy correlated significantly with location (p = .002), pT3 and pT4 tumors (p = .002), age (p = .02), and postoperative radiotherapy (p = .04). No correlation was found with the period of feeding tube (p = .38), or aspiration pneumonia (p = .24). Conclusions. Endoscopic resection of laryngeal and hypopharyngeal tumors is associated with good recovery of deglutition. Many tracheotomies are avoided, the need for a feeding tube is usually reduced, and organ preservation is often feasible even in locally advanced tumors. © 2003 Wiley Periodicals, Inc. Head Neck26: 103,110, 2004 [source] A study of the effect of a resistive heat moisture exchanger (trachinaze) on pulmonary function and blood gas tensions in patients who have undergone a laryngectomy: A randomized control trial of 50 patients studied over a 6-month periodHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2003Andrew Simpson Jones MD Abstract Background. Previous work from this department has shown that resistive tracheostomy filters increase the partial pressure of oxygen in capillary blood and also provide a significant amount of heat/moisture exchange. Until now it has not been shown whether there is any long-term beneficial effect and in particular whether raised tissue oxygenation is maintained using a practical filter device. Methods. We carried out a 6-month randomized control trial including 50 laryngectomees. Twenty-five patients were treated with the Liverpool Heat Moisture Exchange device incorporating an airway resistor (Trachinaze). Another 25 patients were treated with a placebo device. Relevant subjective and objective data were collected before and at the end of the study. The objective measurements were capillary oxygen tension (which parallels blood arterial tension), carbon dioxide tension, FEV1, FVC, and PIF. Patients were reviewed at intervals throughout the study. Data were analyzed using the Mann,Whitney U test and the paired t test to test the difference between the active device and placebo at 6 months. Results. Subjective lower airway parameters, including cough, number of chest infections, mucus production, and shortness of breath at rest, were significantly improved in the active group compared with the placebo group. The objective parameters FEV1, FVC, and PIF were not significantly different. Capillary oxygen tension, however, was highly significantly raised in the active group at 6 months. Conclusions. Trachinaze is highly superior to placebo at improving subjective pulmonary parameters, including shortness of breath. It is also superior in its ability to maintain an increased peripheral tissue oxygen tension over a 6-month period. © 2003 Wiley Periodicals, Inc.

Rustgi Merimepodib (MMPD) is an orally administered, inosine monophosphate dehydrogenase inhibitor that has shown antiviral activity in nonresponders with chronic hepatitis C (CHC) when combined with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV). We conducted a randomized, double-blind, multicenter, phase 2b study to evaluate the antiviral activity, safety, and tolerability of MMPD in combination with Peg-IFN-alfa-2a and RBV in patients with genotype 1 CHC who were nonresponders to prior therapy with Peg-IFN and RBV. Patients received 50 mg MMPD, 100 mg MMPD, or placebo every 12 hours, in addition to Peg-IFN-alfa-2a and RBV, for 24 weeks. Patients with a 2-log or more decrease from baseline or undetectable hepatitis C virus (HCV) RNA levels at week 24 were then eligible to continue Peg-IFN-alfa-2a and RBV for a further 24 weeks, followed by 24 weeks of follow-up. The primary efficacy endpoint was sustained virological response (SVR) rate at week 72 in all randomized patients who received at least one dose of study drug and had a history of nonresponse to standard therapy. A total of 354 patients were randomized to treatment (117 to placebo; 119 to 50 mg MMPD; 118 to 100 mg MMPD), and 286 completed the core study. The proportion of patients who achieved SVR was similar among the treatment groups: 6% (6/107) for 50 mg MMPD, 4% (5/112) for 100 mg MMPD, and 5% (5/104) for placebo (P = 0.8431). Adverse-event profiles for the MMPD combination groups were similar to that for Peg-IFN-alfa and RBV alone. Nausea, arthralgia, cough, dyspnea, neutropenia, and anemia were more common in patients taking MMPD. Conclusion: The addition of MMPD to Peg-IFN-alfa-2a and RBV combination therapy did not increase the proportion of nonresponder patients with genotype 1 CHC achieving an SVR. (HEPATOLOGY 2009.) [source] An Outbreak of Respiratory Diseases among Workers at a Water-Damaged Building , A Case ReportINDOOR AIR, Issue 3 2000MARKKU SEURI Abstract We describe a military hospital building with severe, repeated and enduring water and mold damage, and the symptoms and diseases found among 14 persons who were employed at the building. The exposure of the employees was evaluated by measuring the serum immunoglobulin G (IgG)-antibodies against eight spieces of mold and yeast common in Finnish water and mold damaged buildings and by sampling airborne viable microbes within the hospital. The most abundant spieces was Sporobolomyces salmonicolor. All but one of the employees reported some building-related symptoms, the most common being a cough which was reported by nine subjects. Four new cases of asthma, confirmed by S. salmonicolor inhalation provocation tests, one of whom was also found to have alveolitis, were found among the hospital personnel. In addition, seven other workers with newly diagnosed rhinitis reacted positively in nasal S. salmonicolor provocation tests. Skin prick tests by Sporobolomyces were negative among all 14 workers. Exposure of the workers to mold and yeast in the indoor air caused an outbreak of occupational diseases, including asthma, rhinitis and alveolitis. The diseases were not immunoglobulin E (IgE)-mediated but might have been borne by some other, as yet unexplained, mechanism. [source] |
