    Results. We have examined 80 children aged from 6 months to 3 years with acute obstructive bronchitis, and 40 age-matched children with acute nonobstructive bronchitis. The factors of high risk were determined and the mathematical model for predicting bronchial obstruction in acute bronchitis was created. Father’s age over 38 years, intrauterine growth restriction, maladjustment syndrome, early artificial feeding, genetic predisposition to atopy, passive smoking, fever in the postvaccination period, history of acute obstructive bronchitis and number of its episodes more than 2, paratrophia became prognostically significant. Fever up to 37.7 °C, mild intoxication syndrome up to 3 days, slow nasal breathing, IL-13 within 4.05–6.71 pg/ml and the relative number of lymphocytes expressing NF-kB less than 49.8 % were also associated with the development of bronchial obstruction in acute bronchitis.

    Changes in mucin production and dyscrinia are common features of inflammation in chronic obstructive pulmonary disease (COPD). Immunohistochemical assessment of MUC-2, MUC-3, MUC-4 expression in the integumentary epithelium, goblet cells, the epithelium of mucous glands and stroma fusiform cells of the bronchial mucosa of COPD patients during an infectious and noninfectious exacerbation was performed. 30 patients with stage III COPD were enrolled to the study. Patients were divided into 2 groups: group A - 14 patients with non-infectious acute exacerbation of COPD (AECOPD) and group B - 16 patients with infectious AECOPD. Fiberoptic bronchoscopy (FBS) and in vivo bronchial biopsy of bronchial mucosa were implemented to determine the extent and nature of bronchial inflammation. The optical density of specific color in bronchial structures was assessed using immunohistochemical staining to MUC-2, -3 and -4 antigens by means of primary monoclonal antibodies to these proteins, and visualization system Dako EnVision + System, Peroxidase (AEC). We detected that in different types of bronchial mucosa epithelial cells, during acute infectious exacerbation, a decrease of antigens MUC-2 and MUC-3 expression of a various degree may occur. This phenomenon in the stroma fusiform cells in AECOPD may be a sign of epithelial-mesenchymal transition, that may play a role in the development of an inflammatory process and progression of fibrosis in COPD.

    Combined radiobronchological examination of patients with chronic pneumonia in the phase of reverse development of the disease has been performed. Severity, localization and extent of bronchial obstruction have been studied, depending on the phase of chronic pneumonia and aspects of lung tissue alterations. Bronchial lesions characteristic of chronic pneumonia were defined, as well as importance of x-ray examination methods for bronchial obstruction diagnosis. Three types of bronchial obstruction were distinguished: bronchoconstriction, bronchodilatation and their combination. With regard to the character and severity of bronchial and pulmonary tissue lesions 3 variants of chronic pneumonia are offered to be differentiated: bronchitic, bronchoectatic, and abscess-forming. The main significance in diagnosis of chronic pneumonia is attributed to combined x-ray examination, which also includes radiobronchological investigation in the first two variants of the disease [ru

    Of the bronchographic findings of 408 patients, performed in our hospital for recent 5 years, 108 cases showed definite bronchial obstruction, and 61 cases of those were selected and obstructive findings were evaluated. All that not confirmed were abandoned. For evaluation of the reliability of 9 braonchographic obstruction signs on applying to diagnose malignant or benign pulmonary diseases, each sign was identified and applied to each of the 61 confirmed cases. In addition, obstructed bronchi, distance of obstruction from the bifurcation site, and the direction of meniscus, if present, were evaluated. The results were follows: 1. The most frequent cause of bronchial obstruction was lung cancer (59.0%), and that of the benign obstruction was pulmonary tuberculosis (13.1%). 2. Amputation, asymmetric narrowing, thumbprint indentation, rat-tail narrowing and encasement signs were the most accurate signs of malignancy and were practically diagnostic ones. 3. The most frequent sign in lung cancer was sharp cutoff one, but it could be seen in lung abscess and in unresolved pneumonia, too. 4. Circumferential symmetric narrowing and regular concavity with a small central projection signs were specific ones to benignancy. 5. The most frequent obstruction sign in benign lung disease was gradual tapering sign, but it also could be seen in bronchogenic epidermoid and alveolar cell carcinoma. 6. Of all bronchial obstructions, 55.4% occurred at lobar bronchus and 77.4% of those were caused by lung cancer. 7. 77.2% of those obstruction which located within 3 times distance of the bronchial diameter at the nearest proximal bifurcation site, were lung cancer, but 75.0% of those located at over 3 times distance were benign pulmonary diseases. 8. There were no correlation of the direction of the meniscus at the obstructing end in differential diagnosis between benign and malignant pulmonary diseases

    The authors have studied the modification of the spirometric parameters in four atopic children, during nonallergic diet, after administration of ASA (400 mg). The examination of the respiratory functionality has showed a fall of parameters starting four hours after the challenge and with an increase of respiratory resistance. This bronchospastic reaction persisted for about eighteen hours to diminish 24 h. after administration of 400 mg of ASA. The study of spirometric values has showed a remarkable fall of MMEF, sign of small airways obstruction, but also of FEV1-CV for the involvement of the higher airways. The authors attribute the reaction to the metabolites of arachidonic acid (Leukotrienes) and to their different receptor site on the bronchial mucous membrane target cells. The authors conclude showing the gravity of injury that will induce imprudent administration of ASA in hypersensitive subject.

  8. Bronchial or Laryngeal Obstruction Induced by Exercise?

    Full Text Available A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs in inspiration is observed to reoccur following a deep breath or swallowing. The procedure may thus help diagnosing the site of exercise-induced obstruction when laryngoscopy is not available and identify re-inducers of laryngeal dysfunction.

    Increased airway hyperresponsiveness is a major concern in the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease. Guidelines using evidence-based medicine are continually being updated and published regarding the diagnosis, treatment, and prevention of these respiratory disorders. Perioperative management in these patients involves: (1) adequate control of airway hyperresponsiveness, including detection of purulent sputum and infection before surgery; (2) evidence-based control of anesthesia; and (3) the aggressive use of beta-2 adrenergic stimulants and the systemic administration of steroids for the treatment of acute attacks. Good preoperative control, including the use of leukotriene antagonists, can reduce the incidence of life-threatening perioperative complications. Awareness of recent guidelines is thus important in the management of patients with airway hyperresponsiveness. This review covers the most recent guidelines for the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.

    Airway stenting is a well-established method that relieves symptoms and maintains airway patency in patients with airway obstruction. Serious complications caused by airway stents such as stent dislocation and airway obstruction during surgery are life-threatening. An 80-year-old man was treated with bronchial stent for left bronchus obstruction caused by metastatic esophageal cancer. During tracheostomy surgery, he suffered from acute tracheal obstruction caused by dislocated bronchial stent. Esophageal cancer, left bronchus obstruction, respiratory failure, tracheal obstruction. Threading a 5.0-sized endotracheal tube combined with an Eschmann tracheal tube introducer to prop up the collapsed stent. The bronchial stent was re-expanded and threaded into right main bronchus and ventilation restored. Patient with airway stent undergoing surgery with airway involved should be performed under the support of a backup physician and equipment that are capable of handling potentially life-threatening complications of airway stent. If not, in the emergent situation of tracheal obstruction due to tracheal/bronchial stent, protruding through the stent with a suitable, small-sized endotracheal tube with Eschmann tracheal tube introducer may be an alternative skill for saving life weighted with possible complications.

    Whether the main points of treatment for bronchial obstructive syndrome (BOS) in chronic obstructive lung disease (COLD) can be adapted for patients with pulmonary tuberculosis (PT) was studied. For this purpose, 435 patients with PT with signs of BOS (forced expiratory volume at 1 second (FEV1) 70% of the normal values; 2) 229 patients with FEV1 69-50%; 3) 102 patients with FEV1 bronchial obstructive syndrome in patients with pulmonary tuberculosis was highly effective, promotes the amelioration of the degree of respiratory symptoms in patients with IPT by 2 to 8 times, in those with FCPT by more than 2-3 times, and in those with PS by 1.45-10 times. The differences in the efficiency of bronchodilator therapy depend on the baseline level of bronchial obstruction. In patients with pulmonary tuberculosis concurrent with BO, the use of current inhalation bronchodilator therapy results in a substantial increase in FEV1, which differentiates BOS in PT from COLD. The use of the proposed therapy in the multimodality treatment of patients with pulmonary tuberculosis showed no statistically significant differences in the changes in the degree of X-ray symptoms while this therapy permits acceleration of abacillation in patients with IPT by 16.8% and in those with FCPT by 14.8%. Effective bronchodilator therapy considerably enhances life quality in patients. Thus, early systematic and long-term performance of the bronchodilator therapy, based on the principles of bronchodilator therapy for COLD, in patients with PT concurrent with BOS may substantially enhance the efficiency of treatment in this category of patients.

    Acute gastrointestinal obstruction occurs when the normal flow of intestinal contents is interrupted. The blockage can occur at any level throughout the gastrointestinal tract. The clinical symptoms depend on the level and extent of obstruction. Various benign and malignant processes can produce acute gastrointestinal obstruction, which often represents a medical emergency because of the potential for bowel ischemia leading to perforation and peritonitis. Early recognition and appropriate treatment are thus essential. The typical clinical symptoms associated with obstruction include nausea, vomiting, dysphagia, abdominal pain and failure to pass bowel movements. Abdominal distention, tympany due to an air-filled stomach and high-pitched bowel sounds suggest the diagnosis. The diagnostic process involves imaging including radiography, ultrasonography, contrast fluoroscopy and computer tomography in less certain cases. In patients with uncomplicated obstruction, management is conservative, including fluid resuscitation, electrolyte replacement, intestinal decompression and bowel rest. In many cases, endoscopy may aid in both the diagnostic process and in therapy. Endoscopy can be used for bowel decompression, dilation of strictures or placement of self-expandable metal stents to restore the luminal flow either as a final treatment or to allow for a delay until elective surgical therapy. When gastrointestinal obstruction results in ischemia, perforation or peritonitis, emergency surgery is required. Copyright © 2013. Published by Elsevier Ltd.

    The relationship between obstructive sleep apnea syndrome (OSAS) and bronchial hyperresponsiveness (BHR) is not well known. In this study, we investigated the association between BHR and disease severity in patients with OSAS. Fourty seven (37 male/10 female) OSAS patients admitted with polysomnography enrolled to the study. Histamine bronchial challenge test was performed and body mass index (BMI, kg/m2) was calculated. Presence of BHR was diagnosed as positivity of bronchial provocative test (BPT) (PD values ≤ 16 mg/mL). Patients were questioned with Epworth sleepiness scale (ESS). Histamine bronchial challenge test was positive in 21 of 47 patients. There were significant negative correlations between PD 20 value and AHI (r= -0.47, p= 0.03), BMI (r= -0.45, p= 0.03), and ESS score (r= -0.45, p= 0.03) in the patients with BHR. In addition, AHI (p= 0.03), BMI (p= 0.02), ESS scores (p= 0.03) were higher in patients with BHR (21 patients) than in patients not having BHR (26 patients). Significant negative relation was found between PD 20 value and AHI (b=-0.45, p= 0.03) and significant positive relation was found between presence of BHR and AHI (p= 0.04), BMI (p= 0.03) independently of age and sex in multiple regression analysis. BHR is common in patients with OSAS. As severity of OSAS increased, severity of BHR increased. In addition, obesity may trigger presence of BHR in patients with OSAS.

    To evaluate peculiarities of a clinical course and changes in bronchial mucosa in bronchial asthma (BA) patients with chronic obstructive pulmonary disease (COPD) in combination with hyperoxaluria (HOU); informative value of some laboratory and device findings including oxalates assay in bronchial lavage fluid for specification of the diagnosis, role of oxalates in development of obstructive syndrome and choice of optimal therapy. Oxalates were examined in daily urine, bronchoalveolar lavage fluid and exhaled air condensate of 104 patients with BA and COPD, 77 of which had HOU and an atypical course of bronchial obstruction syndrome. Conception of airways inflammation in patients with oxalate metabolism disturbances is proposed. It is shown that insoluble oxalates participate in pathogenesis of bronchial obstruction. Oxalate metabolism disturbances are an important factor in pathogenesis of airways inflammation and development of bronchial obstruction in predisposed patients. Therefore, administration of insoluble oxalates lowering therapy may effectively prevent formation and progression of obstructive pulmonary diseases in this group of patients.

    Pulmonary hemodynamic disorders depend on the inflammatory phases and severity of the obstructive syndrome. However, the effect of asthma bronchial obstruction on the state of peripheral hemodynamics remains insufficiently known. To study the effects of airway obstruction on skin blood flow parameters and its regulatory systems in patients with persistent atopic bronchial asthma in the remission state. A comparative study of the skin peripheral blood flow in patients with bronchial asthma with severe airway obstruction (1st group) and without obstruction (2nd group) was conducted. 20 patients with confirmed diagnosis of atopic asthma of 50–74 years old participated in the study. All patients received basic therapy in a constant dosing of high doses of inhaled glucocorticosteroids/long-acting beta-2-agonists. The control group included 20 healthy volunteers without evidence of bronchial obstruction. The study lasted for 3 months. The forced expiratory volume in 1 s (FEV1) was used to evaluate the bronchial obstruction by spirometry technique. Skin blood perfusion changes were recorded by laser Doppler flowmetry at rest and in response to short-term local ischemia. Registered peripheral blood flow signals were examined using the amplitude temporal filtering in five frequency intervals to identify the functional features of the peripheral blood flow regulation systems. Consistent two-fold decrease of the oscillation amplitudes was found in the neurogenic interval at rest (p=0.031), as well as in the myogenic (p=0.043; p=0.031) and endothelial intervals (p=0.037; p≤0.001) both at rest and during the postocclusive reactive hyperemia respectively in the 1st group of patients with bronchial obstruction (FEV1 obstruction, FEV1 >80%) in comparison to control subjects. The presence of bronchial obstruction has a significant impact on the changes of the amplitudes of skin blood flow oscillations in patients with bronchial asthma in the myogenic, neurogenic and endothelial

    To study bronchial reactivity and sensitivity with consideration of histamine, serotonin and catecholamines concentration in bronchial mucosa in patients with acute bronchitis (AB) as possible criteria of its becoming chronic. Before the treatment 116 patients with verified AB were examined using inhalation provocative tests (IPT) with histamine, serotonin and obsidian in increasing doses. Also, external respiration function was studied. IPT were repeated after the course of treatment. 87 of 116 AB patients exhibited high bronchial sensitivity and reactivity to inhalations of histamine, serotonin, obsidian. In parallel, there was a rise in the levels of histamine and serotonin and a fall in the level of catecholamines in bronchial mucosa (alveolar macrophages, lymphocytes, neutrophils, mast and APUD-cells). Changes in monoamines concentration in bronchial mucosa were relevant to activity of bronchial inflammation and the presence of obstructive syndrome. Persistent bronchial hyperreactivity to inhalations of histamine and obsidian along with high histamine levels and low level of catecholamines in alveolar macrophages, lymphocytes and mucus is a criterion of bronchitis transformation to chronic one.

    Full Text Available The research goal was to formulate and substantiate the hypothesis explaining support for an expiratory air flow in case of pulmonary emphysema. The research method consisted in comparing the mechanical properties of lungs in practically healthy individuals (37 individuals, mean age – (30.4 ± 1.7 y.o. and COPD patients with pronounced lung emphysema (30 patients, mean age – (52.1 ± 2.3 y.o. as well as those of isolated normal lungs (n = 14 and isolated lungs of patients who died of COPD (n = 5. Pulmo-nary mechanics was studied via the simultaneous measurement of transpulmonary pressure and lung ven-tilation volume. General lung hysteresis and elastic lung hysteresis were calculated. The mechanical properties of isolated lungs were studied using passive ventilation under the Donders bell. The air flow was interrupted in order to measure alveolar pressure and develop an elastic lung hysteresis curve. Pres-sure in the Donders bell was changed by means of a special pump in automatic and manual modes. The research has not revealed any fundamental differences between the mechanical properties of the normal and emphysematous lungs. A minimum increase in the pressure inside the Donders bell over atmospheric pressure used to stop air ejection in both normal and the emphysematous lungs as the result of flap-valve bronchial obstruction. In living beings, air is ejected from lungs with an increase in pressure under the conditions of forced expiration. Pressure increases up to (38.6 ± 2.71 cm H2O in healthy individuals and up to (20.5 ± 1.86 cm H2O in COPD patients. Probably, an expiratory air flow is supported by active expiratory bronchial dilatation that counteracts flap-valve bronchial obstruction. The hypothesis is based on the confirmed ability of the lungs to perform inspiratory actions (in addition to the action of respiratory muscles and the theory of mechanical lung activity.

    Full Text Available On the base of a complex examination of 215 schoolchildren who suffer bronchial asthma, there have been established that clinical manifestations of severity of bronchial obstructive syndrome during disease exacerbation do not depend on acetylating status. However, a homozygosity on both alleles of the glutathione transferase gene (GSTT1+M1+ has been connected to greater severity of asthma attacks, while a lack of the T-allele in children with slow acetylating phenotype has been associated with more frequent use of systemic corticosteroids and somewhat better results of airways obstruction relief therapy. Occurrence of GSTT1+M1+ genotype in patients with accelerated processes of acetylation significantly increased the risk of the inefficiency of bronchial obstruction relief therapy (odds ratio 12.4, relative risk — 6.4, the absolute risk — 50 %.

    The effects of continuous positive airway pressure (CPAP) treatment on the function of the lower airways are poorly understood. One of the methods used to determine the influence of positive pressure breathing on lower airways is the bronchial hyperreactivity test. Some authors report that CPAP increases bronchial hyperreactivity, while others report decreases. To assess the influence of CPAP treatment on bronchial reactivity and the effects of bronchial hyperreactivity on compliance to CPAP treatment. The study group consisted of 101 obstructive sleep apnea syndrome patients (88 men and 13 women) with a mean age of 51 ± 11 years, mean apnea-hypopnea index of 53 ± 20 and mean body mass index of 32.6 ± 5.4. Patients were randomly assigned to a treatment group that received 3 weeks of CPAP therapy (group 1) or to a nontreatment control group (group 2). Pulmonary function tests and the methacholine bronchial provocation test were performed at baseline and 3 weeks later. There were no statistically significant differences between treated and control groups in anthropometry and polysomnography variables. At baseline, bronchial hyperreactivity was found in 6 patients from group 1 and 5 patients from group 2. A significant increase in bronchial reactivity was observed after CPAP treatment. Log PC20M decreased from 1.38 ± 0.30 at baseline to 1.26 ± 0.50 (p bronchial hyperreactivity during CPAP treatment were characterized by significantly lower FEV1, FVC and MEF50 values. CPAP produces statistically significant bronchial hyperreactivity. However, there were no clinical symptoms and it is not necessary to withdraw previous therapies. Copyright © 2009 S.

    One of more frequent reasons for hospitalizations concerning infants and small children are obstructive bronchitis. Great prevalence of bronchial tree obturation during infancy and in small children is a result of anatomical and functional differences of airways and immunological differences that occur in infants and small children. The most frequent cause of bronchial tree obturation is infection induced by viruses, rarely by bacteria. Recurrences of bronchial tree obturation are observed in some patients. Obturation recurrences can be caused by number of diseases that appear during infancy and in small children, for example cystic fibrosis of the pancreas. Also the presence of foreign body in the airways, immotile cilia syndrome, immunological disturbances, innate anomalies of the respiratory system and the circulatory system and bronchial asthma can result in obturation recurrences. Various clinical criteria are established and new markers of allergic inflammation are searched in view of difficulties to diagnose bronchial asthma in the youngest children. There are no unequivocal rules to diagnose bronchial asthma in infants and small children despite these searches.

    Inhaled bronchodilators are the mainstay of pharmacological treatment for stable chronic obstructive pulmonary disease (COPD), including β2-agonists and muscarinic antagonists. Tiotropium bromide, a long-acting antimuscarinic bronchodilator (LAMA), is a treatment choice for moderate-to-severe COPD; its efficacy and safety have been demonstrated in recent trials. Studies also point to a beneficial role of tiotropium in the treatment of difficult-to-control asthma and a potential function in the asthma-COPD overlap syndrome (ACOS). Combination of different bronchodilator molecules and addition of inhaled corticosteroids are viable therapeutic alternatives. A condensation of the latest trials and the rationale behind these therapies will be presented in this article.

    Full Text Available Bronchial foreign body obstruction is common in all clinical settings. Obstruction of the airway due to foreign bodies and foreign body aspiration are major causes of childhood mortality and morbidity, which are a big challenge to manage. Occasionally, bronchial obstruction may be due to mucus plugs or other endogenous factors. Here we describe a case of bronchial obstruction caused by mucus plug formation that was managed conservatively in a one-year old boy. The patient was suffering from a cough and noisy breathing for 2 days prior to coming to our hospital, when he experienced sudden onset of difficulty in breathing and a severe cough. At the time of presentation his vital sign readings were:- HR 186 bpm, RR 46/min, BP 78/40 MmHg, temp 36.9°C and SPO2 68%. He was given oxygen immediately and nebulization was started. Chest CT scan was performed that suggested the presence of a right bronchial foreign body with right sided obstructive emphysema. The patient was stable with oxygenation and nebulization with ipratropium bromide, albuterol, normal saline and budesonide before the CT scan. Therefore, we conclude that symptoms resembling foreign body obstruction are not always aspirated or inhaled, and sometimes secreted sputum forms a plug, which mimics the symptoms of foreign body obstruction.

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

    Full Text Available Objective. To investigate the effect of bronchial obstruction syndrome on perioperative characteristics in patients undergoing coronary artery bypass grafting (CABG.Methods. Body plethysmography and spiroergometry at rest were used to study respiratory function and consumption of O2. To evaluate the effectiveness of pulmonary ventilation, the oxygen utilization coefficient of (O2CU was calculated in 178 patients prior to scheduled surgery. The relationship of external ventilation parameters and perioperative clinical characteristics was analyzed. Results. A bronchial obstruction syndrome was detected in 30 (16.9% patients, with 21 (11.2% of them having no chronic obstructive pulmonary disease diagnosis. 4 patients (2.3% with obstructive pulmonary disease had no bronchial obstruction. Thus, chronic obstructive pulmonary disease was misdiagnosed in 13.5% cases. In patients undergoing isolated CABG, negative relationship was revealed between the Tiffno index and hospital stay (regression coefficient –6.9, 95%, confidence interval –14.4… 0.6; p = 0.07. In patients operated with the myocardium stabilized, bimammary grafting tended to increase hospital stay by an average of 4.3 days (95% CI 1.5–7.1; p=0.003. The majority of patients had a low O2CU. O2CU lower than 16.2 ml/l is associated with an increased risk of postoperative atrial fibrillation (AF in the postoperative period (OR 2.96; 95% CI 1.01–9.83; p = 0.04. No significant associations were observed between the degree of bronchial obstruction and the number of perioperative complications. Conclusion. The degree of bronchial obstruction could be positively associated with the length of hospital stay. A critically low level of O2CU is explained by an increased risk of postoperative AF. Further research might result in the identification of predictors for respiratory complications and long-term mortality in patients after CABG.

    Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

    Obstructive sleep apnoea syndrome is associated with significant morbidity. A high prevalence of obstructive sleep apnoea (OSA) symptoms has been reported in patients with asthma and chronic obstructive pulmonary disease (COPD). There are limited studies regarding relationship between atopy and OSA. To study the risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients by a home based sleep study and its association with atopy. Patients with asthma and COPD were evaluated for OSA symptoms by Epworth sleepiness scale (ESS) and Berlin questionnaire (BQ). ESS score > or = 9 was considered as high risk for OSA. Patients having high risk for OSA by ESS and BQ were further evaluated for OSA by home based sleep study. Skin prick test against common allergens was done to diagnose atopy in these patients. Among 400 patients (229, 57.25% male and 171, 42.75% female) 328 were asthmatics and 72 were COPD patients. ESS and BQ was positive in 11.25% (45/400) and 18.25% (73/400) patients respectively. ESS was positive in 10.67% (35/328) of asthma and 13.88% (10/72) of COPD patients. BQ was positive in 18.29% (60/328) of asthmatic and 18.05% (13/72) of COPD patients. Skin prick test was positive in 74.16% patients. The maximum positivity was found in asthmatics (139/155, 89.68%) compared to COPD patients (16/155, 10.32%). Skin prick test was done for 40 patients out of 73 of Asthma and COPD patients who were found positive by ESS and BQ. 72.5% patients were found to be atopic. Out of 19 patients in whom home polysomnography was done, 13 patients consented for skin prick test with common aeroallergens and 9 (69.23%) patients were found to be atopic. There is an increased risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients. Atopy could be associated with OSA. The association needs to be proved in a larger study.

    1996-01-01

    The paper provides the results of a follow-up of 70 patients with active pulmonary tuberculosis in whom the administration of antituberculous drugs induced eosinophilia and bronchial obstructive syndrome. To eliminate the side effects of antituberculous therapy, a plasmapheresis regimen was performed in 44 patients, the remaining patients were given only bronchodilators and antihistamine drugs. Plasmapheresis as a means for correcting drug-induced eosinophilia and bronchial obstructive syndrome was found to be more effective than drug therapy and, in some cases, enabled antituberculous therapy to be continued, without changing a combination of drugs. It is recommended that plasmapheresis should be used in cases of inadequate efficiency of conventional methods for correcting drug intolerance.

    Exercise-induced laryngeal obstruction (EILO) is a key differential diagnosis for asthma in the presence of exertional respiratory symptoms. Continuous laryngoscopy during exercise (CLE), the current gold standard diagnostic test for EILO, has practical limitations. We aimed to establish if inspiratory flow data obtained during standard bronchoprovocation testing, to establish the presence of extra-thoracic hyper-responsiveness, may prove diagnostic for EILO and thus preclude requirement for CLE testing. We consecutively evaluated 37 adult subjects with exertional dyspnea and possible asthma referred over 6 months. All subjects received comprehensive assessment including a detailed clinical evaluation; pulmonary function testing, indirect and direct bronchial provocation testing, and CLE testing. Out of 37 subjects, moderate or severe EILO was diagnosed in 8 subjects (22%, all female) while 5 (14%) had both asthma and EILO. There was no correlation between degree of EILO during CLE and mean decrease in forced inspiratory flow (%FIF 50 ) obtained during neither the Methacholine (r = -0.15; p = 0.38) nor Mannitol (r = 0.04; p = 0.84) provocation tests. Inspiratory flow parameters obtained during bronchoprovocation tests did not reliably detect EILO. It remains that CLE is an important and key investigation modality in establishing a secure diagnosis of EILO.

    The aim of this study was to determine the prevalence of airway malacia and its relationship with ancillary morphologic features in patients with chronic obstructive pulmonary disease (COPD). A retrospective review was performed of a consecutive series of patients with COPD who were imaged with inspiratory and dynamic expiratory multidetector computed tomography (MDCT). Airway malacia was defined as ≥50% expiratory reduction of the airway lumen. Both distribution and morphology of airway malacia were assessed. The extent of emphysema, extent of bronchiectasis and severity of bronchial wall thickness were quantified. The final study cohort was comprised of 71 patients. Airway malacia was seen in 38 of 71 patients (53%), and such proportion was roughly maintained in each stage of COPD severity. Almost all tracheomalacia cases (23/25, 92%) were characterised by an expiratory anterior bowing of the posterior membranous wall. Both emphysema and bronchiectasis extent did not differ between patients with and without airway malacia (p > 0.05). Bronchial wall thickness severity was significantly higher in patients with airway malacia and correlated with the degree of maximal bronchial collapse (p < 0.05). In conclusion, we demonstrated a strong association between airway malacia and COPD, disclosing a significant relationship with bronchial wall thickening. (orig.)

    Full Text Available Abstract Background Environmental pollution is a risk factor for cardiorespiratory diseases. Energy generated by thermoelectric power plants (TEPP represents a relevant source of pollution. The aim of this study was to evaluate the relationship between living near a coal-fired TEPP and the consultation rates for bronchial obstructive crises (BOC in the province of Concepción, Chile. Methods Population-based study. The epidemiological weeks from 2012 to 2014 were analyzed. The dependent variable was the emergency consultation rate for BOC in two health centers within 5 km of a TEPP (Coronel and two that were more than 40 Km away from a TEPP (Talcahuano. The independent variables were the commune, climatological variables (air temperature and relative atmospheric humidity, environmental pollutants (PM10, PM2.5 and nitrogen oxide, weeks with the highest consultation rate and the years. Rates, Pearson’s correlation and gross risk measures were calculated and adjusted for environmental and climatological variables. Results BOC rates were significantly higher in Coronel (RR = 4.9 95% CI 4.0–5.8; p < 0.05. The PM2.5 it showed the strongest correlation with BOC rates (r = 0.3; p < 0.01 in Coronel, but not Talcahuano. Linear regression modelling indicated that proximity to a TEPP (health center location and temperature explained 26 and 18% of the variance in BOC rates, respectively. Conclusions Rates of emergency consultation for BOC were significantly higher among a population living within 5 km of a coal-fired TEPP than those living 40 km away.

    Full Text Available Mauricio González-García,1,2 Carlos A Torres-Duque,1,2 Adriana Bustos,1 Claudia Jaramillo,1 Darío Maldonado1,21Fundación Neumológica Colombiana, 2Universidad de la Sabana, Bogotá, ColombiaPurpose: Chronic obstructive pulmonary disease (COPD related to wood smoke exposure is characterized by important inflammation of the central and peripheral airways without significant emphysema. The objective of this study is to describe the bronchial hyperresponsiveness (BHR level in women with COPD related to wood smoke exposure and to compare it with the BHR in women with COPD related to tobacco smoking.Materials and methods: Two groups of women with stable COPD were studied: (1 wood smoke exposed (WS-COPD; and (2 tobacco smoke exposed (TS-COPD. A methacholine challenge test (MCT was performed in all patients according to American Thoracic Society criteria. BHR levels were compared using the methacholine concentration, which caused a 20% fall in the FEV1 (PC20.Results: Thirty-one patients, 19 with WS-COPD and 12 with TS-COPD, were included. There were no significant differences between the groups in baseline FVC, FEV1, IC, FEF25–75, and FEF25–75/FVC. All 31 patients had a positive MCT (PC20 , <16 mg/mL and the fall in the FEV1 and IC was similar in both groups. The severity of BHR was significantly higher in the WS-COPD patients (PC20: 0.39 mg/mL than in the TS-COPD patients (PC20: 1.24 mg/mL (P = 0.028. The presence of cough, phlegm, and dyspnea during the test were similar in both groups.Conclusion: We found moderate to severe BHR in women with WS-COPD, which was more severe than in the TS-COPD women with similar age and airflow obstruction. This paper suggests that the structural and inflammatory changes induced by the chronic exposure to wood smoke, described in other studies, can explain the differences with TS-COPD patients. Future studies may clarify our understanding of the impact of BHR on COPD physiopathology, phenotypes, and treatment

    In pediatrics, identifying the severity of bronchial obstruction in an early manner is a decisive factor. To assess the psychometric properties of the scales for grading the severity of bronchial obstruction in pediatric patients. This was a systematic review of studies on the validity and reliability of scales for grading the severity of bronchial obstruction conducted in infants and children younger than 3 years old. The search was conducted in Medline, WoS, EMBASE, SciELO, and Google Scholar. The correlation coefficient corresponding to each article was included in a random effects model to establish the criterion validity and reliability using the weighted averages of coefficients as per the sample size. A total of 9 articles were included, which accounted for 2699 children; 3 articles had an adequate or excellent methodological quality. Four articles established the concurrent criterion validity considering oxygen saturation, with a weighted correlation coefficient of -0.627 (95% confidence interval [CI]: -0.767 to -0.431, p reliability, with a weighted correlation coefficient of0.500for kappa and 0.891 for the intraclass correlation coefficient. The assessment of psychometric properties to support the use of scales for grading the construct "severity of bronchial obstruction" showed a moderate to adequate criterion validity. The percentage of agreement among observers in terms of the studied measure (severity of bronchial obstruction) was adequate; however, weaknesses such as the article design should be taken into account since it may affect the internal validity of results.

    We have investigated the motility effects of acute experimental canine intestinal obstruction. A 30-min midjejunal obstruction was produced by clamping a Biebl loop or by inflating an intraluminal balloon. Spike bursts from serosal electrodes proximal to the site of obstruction increased markedly, while those from distal electrodes decreased. When the obstruction from an intraluminal Foley catheter was continued for 5.5 h, the inhibition persisted distally but the proximal contractile activity gradually fell to control levels. The reduced proximal activity after prolonged obstruction was largely due to clusters of regular intense spike bursts preceded and followed by lengthening periods of absent motor activity. Similar clustered contractions obliterated the lumen when the passage of barium through a Thiry-Vella loop was monitored fluoroscopically. Significant motility changes occur in intestinal obstruction, but an increased understanding of the mechanisms involved awaits future studies.

    We studied the role of oxalate release through the airways as a potential injurious factor in the development of inflammation, bronchial obstruction and cough syndrome (respiratory oxalosis). Detection of oxalates in bronhcoalveolar lavage fluid and daily urine is the most valuable method for diagnostics of oxalates. Systemic effects, such as cholelithiasis, urolithiasis, and spinal osteochondrosis are characteristic clinical signs of respiratory oxalosis, besides purely respiratory symptoms.

    Chronic obstructive pulmonary disease (COPD) is defined as a syndrome characterized by usually progressive chronic airflow limitation which is associated to a bronchial hyperresponsiveness and is partially reversible. Noninvasive mechanical ventilation is an alternative treatment for patients with COPD exacerbations. The objective of the literature reviews was to verify noninvasive mechanical ventilation benefits and complications in acute exacerbations of chronic obstructive pulmonary disease in patients. This national and international's scientific literature review was developed according to criteria established for documentary research in the MedLine, LILACS, SciElo, PubMed and Cochrane, databases using the key words: chronic obstructive pulmonary disease and noninvasive mechanical ventilation. Inclusion criteria were articles published from 1995 to 2007; in English, Spanish and Portuguese; studies in the human model and with no gender restriction. Noninvasive mechanical ventilation can reduce partial pressure of carbon dioxide, improve gas exchange, alleviate symptoms as dyspnea caused by fatigue of the respiratory muscles, reduce duration of hospitalization, decrease need for invasive mechanical ventilation, reduce number of complications and also lessen hospital mortality. The main complications found were: facial skin erythema, claustrophobia, nasal congestion, face pain, eye irritation, aspiration pneumonia, hypotension, pneumothorax, aerophagia, hypercapnia, gastric insufflation, vomit, bronchoaspiration, morning headaches, face injuries, air embolism and, last but not least, discomfort of the patient. Noninvasive mechanical ventilation can be more effective in patients with moderate-severe exacerbations of COPD and these complications can be minimized by an adequate interface also by the contribution of the physiotherapist experience.

    Chronic obstructive pulmonary disease (COPD) is among the leading causes of morbidity and mortality worldwide. Glucocorticoids are currently the most applicable anti-inflammatory treatment for COPD. However, a subset of COPD subjects is relatively insensitive to this treatment. Fenspiride, a non-corticosteroid anti-inflammatory drug, has been described to have beneficial effects in patients with COPD, although the mechanism of its action is not well known. The effect of fenspiride on contract...

    INTRODUCTION: Exercise-induced laryngeal obstruction (EILO) is a key differential diagnosis for asthma in the presence of exertional respiratory symptoms. Continuous laryngoscopy during exercise (CLE), the current gold standard diagnostic test for EILO, has practical limitations. We aimed...... to establish if inspiratory flow data obtained during standard bronchoprovocation testing, to establish the presence of extra-thoracic hyper-responsiveness, may prove diagnostic for EILO and thus preclude requirement for CLE testing. METHODS: We consecutively evaluated 37 adult subjects with exertional dyspnea...

    The lung has a diverse microbiome that is modest in biomass. This microbiome differs in asthmatic patients compared with control subjects, but the effects of clinical characteristics on the microbial community composition and structure are not clear. OBJECTIVES: We examined whether the composition and structure of the lower airway microbiome correlated with clinical characteristics of chronic persistent asthma, including airflow obstruction, use of corticosteroid medications, and presence of airway eosinophilia. METHODS: DNA was extracted from endobronchial brushings and bronchoalveolar lavage fluid collected from 39 asthmatic patients and 19 control subjects, along with negative control samples. 16S rRNA V4 amplicon sequencing was used to compare the relative abundance of bacterial genera with clinical characteristics. RESULTS: Differential feature selection analysis revealed significant differences in microbial diversity between brush and lavage samples from asthmatic patients and control subjects. Lactobacillus, Pseudomonas, and Rickettsia species were significantly enriched in samples from asthmatic patients, whereas Prevotella, Streptococcus, and Veillonella species were enriched in brush samples from control subjects. Generalized linear models on brush samples demonstrated oral corticosteroid use as an important factor affecting the relative abundance of the taxa that were significantly enriched in asthmatic patients. In addition, bacterial α-diversity in brush samples from asthmatic patients was correlated with FEV1 and the proportion of lavage eosinophils. CONCLUSION: The diversity and composition of the bronchial airway microbiome of asthmatic patients is distinct from that of nonasthmatic control subjects and influenced by worsening airflow obstruction and corticosteroid use.

    Obstructive sleep apnea syndrome (OSAS) has been shown to be associated to upper and lower airways inflammation. Continuous positive airway pressure (CPAP) is the elective treatment of OSAS. The aim of the present study was to assess the effect of CPAP-therapy on airway and nasal inflammation. In 13 non-smoking subjects affected by untreated OSAS and in 11 non-smoking normal volunteers, airway inflammation was detected by analyses of the induced sputum. In the OSAS group measurements were repeated after 1, 10 and 60 days of the appropriate CPAP treatment. In addition, in 12 subjects of the OSAS group, nasal inflammation was detected by the analysis of induced nasal secretions at baseline, and after 1, 10 and 60 days of CPAP treatment. OSAS patients, compared to normal controls, showed at baseline a higher percentage of neutrophils and a lower percentage of macrophages in the induced sputum. One, 10 and 60 days of appropriate CPAP-therapy did not change the cellular profile of the induced sputum. In addition, in the OSAS patients, the high neutrophilic nasal inflammation present under baseline conditions was not significantly modified by CPAP-therapy. Finally, no patients developed airway hyper-responsiveness after CPAP therapy. In OSAS subjects, the appropriate CPAP-therapy, while correcting the oxygen desaturation, does not modify the bronchial and nasal inflammatory profile.

    Full Text Available Background. The main reason for urgent complications of colon cancer is an acute intestinal obstruction (AIO. This is complex pathological condition in 90 % of cases caused by colorectal cancer (CRC.Objective – to evaluate radicality of the performed operations in complicated colorectal cancer in general surgical hospitals. Dependence of the severity of intestinal obstruction by tumor localization, its morphological characteristics, determine dependence of the type of the surgical operation performed on the severity of intestinal obstruction.Materials and methods. We have studied the data on 667 patients with colorectal cancer complicated by acute intestinal obstruction. These patients were treated in the period from 2001 to 2013 in general surgical hospital in the territory of Smolensk and Smolensk region. For the processing of the obtained results we have used software Statistica 6.1. Differences were considered statistically at p ≤ 0.05.Results. All the patients were divided into 3 groups by the expression of intestinal obstruction. Group 1 (n = 279 consisted of patients with the presence of decompensated intestinal obstruction (DIO, group 2 (n = 313 consisted of patients with subcompensated intestinal obstruction (SIO, group 3 (n = 75 included patients with compensated intestinal obstruction (CIO. In case of tumor localization in right halfof the colon we most commonly observed clinical picture of acute development of decompensated intestinal obstruction (p = 0.041. Subcompensated intestinal obstruction prevailed in case of tumor localization in left half of the colon and rectal localization. In general surgical hospitals it is not always possible to speak about radicality of surgical treatment, as in a large number of cases (62.5 % the number of examined lymph nodes was less than 4. When DIO patients are admitted in the clinic, the percentage of singlestage operations is equal to 7.5 % (n = 21. In case of DIO and SIO there was a high

    Bronchiectasis can adversely affect quality of life. However, the tests examining quality of life in bronchiectasis are not sufficient. We examined the validity of a measure designed for COPD, the Seattle Obstructive Lung Disease Questionnaire (SOLQ), in bronchiectasis. In addition, we aimed to compare the quality of life of subjects with bronchiectasis and bronchial hyper-responsiveness with that of those without to identify the effective factors. We studied 78 subjects with clinically stable bronchiectasis and 41 healthy controls matched for age and sex. Subjects were assessed by the SOLQ. A detailed history, physical examination, the Medical Outcomes Study 36-Item Short Form questionnaire, the Hospital Anxiety and Depression Scale, and spirometric measurements were obtained. Cronbach α coefficients, which reflected internal consistency, were >0.70 for all SOLQ components except for treatment satisfaction. SOLQ component scores correlated with all of the component scores of the Medical Outcomes Study 36-Item Short Form questionnaire and the Hospital Anxiety and Depression Scale, confirming their concurrent validity. All SOLQ scores correlated positively with percent-of-predicted FEV1, whereas the physical function, treatment satisfaction, and emotional function correlated negatively with the exacerbation frequency in Pearson analysis. Emotional and physical functions were positively associated with percent-of-predicted FEV1 in linear regression analysis. Compared with subjects without bronchial hyper-responsiveness, those with bronchial hyper-responsiveness had lower FEV1/FVC and more exacerbations/y. Compared with bronchiectasis subjects without bronchial hyper-responsiveness, those with bronchial hyper-responsiveness had significantly lower SOLQ, physical function, and coping skills scores but not emotional function and treatment satisfaction. The SOLQ is a valid instrument for determining quality of life in subjects with bronchiectasis. Subjects with

    Emergency management of obstructing colonic cancer depends on both tumor location and stage, general condition of the patient and surgeon's experience. Right sided or transverse colon obstructing cancers are usually treated by right hemicolectomy-extended if necessary to the transverse colon-with primary anastomosis. For left-sided obstructing cancer, in patients with low surgical risk, primary resection and anastomosis associated with on-table irrigation or manual decompression can be performed. It prevents the confection of a loop colostomy but presents the risk of anastomotic leakage. Subtotal or total colectomy allows the surgeon to encompass distended and fecal-loaded colon, and to perform one-stage resection and anastomosis. Its disadvantage is an increased daily frequency of stools. It must be performed only in cases of diastatic colon perforation or synchronous right colonic cancer. In patients with high surgical risk, Hartmann procedure must be preferred. It allows the treatment of both obstruction and cancer, and prevents anastomotic leakage but needs a second operation to reverse the colostomy. Colonic stenting is clinically successful in up to 90% in specialized groups. It is used as palliation in patients with disseminated disease or bridge to surgery in the others. If stent insertion is not possible, loop colostomy is still indicated in patients at high surgical risk. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Full Text Available The paper presents the data on research of aspiration syndrome prevalence among young children treated in the City children’s pulmonary department due to protracted course of obstructive bronchitis. The structure of microaspiration reasons in young children was studied (2010–2015. The most significant reasons of microaspiration syndrome development were revealed depending on children age. Modified questionnaire for the parents was used to collect anamnesis effectively. The children with perinatal impairment of nervous system, preterm children, and the children with morphological and physio­logical nasopharyngeal defects, with muscular dystonia are firstly in risk group for microaspiration syndrome. Microaspiration may manifest with frequent regurgitation, vomiting during cough, meal leaking from the nose, correlation of coughing fit with feeding, exacerbation or development of coughing in prone position, fit of night coughing and asphyxia, long-term hacking after cough attack. Pediatricians are recommended to observe attentively their patients during each feeding as dysphagy could be inconstant. Microaspiration syndrome is a challenging for diagnosis and requires complex approach, as mostly diagnostic procedures are invasive. Timely diagnosis and treatment of microaaspiration syndrome allow decrease respiratory diseases rate in young children and reduce obstructive bronchitis duration.

    Acute epiglottitis is an acute inflammation in the supraglottic region of the oropharynx which is a potentially life-threatening condition leading to rapid upper airway obstruction. An infrequent sequel of acute epiglottitis is the epiglottic abscess. Less than 50 cases have been reported in the international literature and even less are the cases that acute surgical intervention was necessary to secure the airway. We report a young man with sudden onset of odynophagia, dysphonia and dyspnea and rapidly progression of upper airway obstruction. Clinical examination with fiberoptic nasopharyngolaryngoscope in emergency department demonstrated an epiglottic abscess. An urgent tracheostomy was performed in order to secure patient's airway and afterward, the patient underwent direct laryngoscopy and drainage of abscess and intravenous antibiotics were administrated. The diagnosis of epiglottic abscess should be considered in adult patients with odynophagia and dysphonia. Principles of treatment include aggressive airway management, surgical drainage of abscess and intravenous antibiotics. (author)

    To identify whether there is an association between an acute attack of childhood bronchial asthma and Chlamydia pneumoniae (CP) infection. Serum specific antibodies IgM and IgG to CP were detected by ELISA in 120 asthmatic children with an acute attack and 82 healthy children. Anti-CP IgM was demonstrated in 22 cases (18.3%) and anti-CP IgG was demonstrated in 32 cases (26.7%) out of the 120 asthmatic patients. The incidence of CP infection in asthmatic children was significantly higher than that in healthy controls (3.7%) (P attack of asthma in 15 cases out of the 32 cases with CP infection, but 17 cases required glucocorticoid inhalation treatment together with anti-CP infection treatment (macrolide antibiotics, eg. azithromycin) for remission of asthma attack. There may be a link between an acute attack of childhood asthma and CP infection. It is thus necessary to detect the CP-specific antibodies in asthmatic children for proper treatment.

    To identify the patterns and the correlation of morphological and functional changes in stomach wall with the dynamics of different types of acute intestinal obstruction. The study was performed on 33 adult mongrel dogs of both genders weighing 17-20 kg. All researches were conducted in accordance with the documents, such as the 'Guide for the Care and Use of laboratory animals of the National Institute of Health (National Institute of Health - NIH, Bethesda, USA)' and 'Rules of work with experimental animals'. The same methods were used to study the morphology of stomach wall in normal conditions and after intestinal obstruction simulation. We used H & E stain, Van Gieson's picrofuchsin staining combined with Mallory. The choice of histochemical methods was determined by the need to study metabolic processes in epithelial cells and gastric mucosa glands. Einarson method for detecting total nucleic acids was used. The last group of methods was statistical analysis. We determined the regularities of structural organization of microcirculation in various parts of the stomach, the correlation of morphological and functional changes in stomach wall with the dynamics of different types of acute intestinal obstruction. Our data indicate proximal-distal gradient of gastric perfusion: the most pronounced vascular network and maximum blood flow are observed in proximal stomach in both normal conditions and acute intestinal obstruction. More tenuous and reduced blood flow was revealed in the antrum, that is morphological basis of the most frequent localization of acute ulcers in this department.

    Impulse oscillometry (IOS) is a good method for measuring airway resistance. The aim of this study was to assess the diagnostic contribution of IOS combined with bronchial dilation test (BDT) when distinguishing between patients with asthma and those with chronic obstructive pulmonary disease (COPD). 870 were enrolled in the study including 561 patients with asthma, 100 patients with COPD and 209 patients with chronic coughing or normal subjects. All the participants underwent routine pulmonary function tests, IOS and BDT examination. And IOS examination was before and after BDT. IOS parameters (R5, R20, R25, R35, X5, X20, X25, X35, Fres, Zrs & RP) and forced expiratory volume in one second (FEV1) were recorded. Receiver operating characteristics (ROC) curve analysis was performed to evaluate the diagnostic ability to differentiate asthma and COPD. The discriminative power of the various parameters studied was determined by means of ROC curves: the area under the curve (AUC), sensitivity and specificity. The X5, X20, X25, X35, Fres, Zrs and Rp correlated better with COPD. In particular, X5, Fres and X25 have been found to be significantly correlated with COPD. The diagnostic efficiency of X5, Fres and X25 when diagnosis COPD, expressed by ROC curve parameters, was as follows: AUC (0.725, 0.730, 0.724), sensitivity (67%, 77%, 83%) and specificity (68%, 65%, 58%), respectively. The diagnostic efficiency of Zrs, R5 and X35 when diagnosis asthma, expressed by ROC curve parameters, was as follows: AUC (0.721, 0.710, 0.695), sensitivity (62%, 72%, 53%) and specificity (72%, 61%, 76%), respectively. Our findings show, that X5, X25 and Fres may be useful for predictions and evaluations for COPD. And R5, X35 and Zrs may provide useful IOS parameters for asthma. IOS combined BDT could be useful diagnostic and differential diagnosis between asthma and COPD.

    Few studies to date have investigated the antioxidant nutrients such as vitamin C (ascorbic acid), vitamin E (α-tocopherol), retinol and carotenoids in plasma from patients with pulmonary disease in Japan. To clarify the role of antioxidant nutrients such as vitamin C, vitamin E, retinol and various carotenoids in plasma of Japanese patients with chronic obstructive lung diseases (COPD), asthma-COPD overlap syndrome (ACOS) and/or bronchial asthma (BA), we compared to healthy elderly controls. Ascorbic acid (AA), carotenoids (lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene and lycopene), retinol and α-tocopherol levels in plasma were determined by using a high performance liquid chromatography. Reduced glutathione (GSH), oxidised glutathione (GSSG) in whole blood and urinary 8-OHdG were also determined. Plasma AA level of COPD subjects was significantly lower than that of healthy elderly people. Conversely, ACOS and BA subjects showed no significant difference from healthy elderly people. Moreover, plasma lycopene and total carotenoid levels and GSH content in blood were significantly lower in COPD subjects than these in healthy elderly people. However, other redox markers such as GSSG, GSH/GSSG ratio and urinary 8-OHdG found no significant differences between COPD, ACOS and BA compared to healthy elderly people. These results suggested that COPD of Japanese patients may develop partly because of oxidative stress derived from a shortage of antioxidant nutrients, especially of AA and lycopene, as well as GSH while this may not be the case in both ACOS and BA. © 2016 John Wiley & Sons Ltd.

    Endothelin-1 (ET-1) has been implicated in the pathogenesis of asthma and chronic obstructive pulmonary disease (COPD). The ET-1 levels are elevated during exacerbations of asthma and COPD in bronchoalveolar lavage, serum, and sputum and fails with treatment of the exacerbations. Hypoxemia stimulates ET-1 secretion. The aim of this study was to examine the serum ET-1 levels in stable asthmatic and COPD patients. We examined 48 COPD and 26 asthmatic patients and 34 normal subjects. We collected arterial samples to measure baseline ET-1 levels in all patients and in the control group, during the day. All the patients underwent formal polysomnography (EEG, ECG, airflow, respiratory muscle movement, oximeter) to detect the presence of nocturnal, nonapneic, and oxyhemoglobin desaturation. Twelve of the COPD patients and six of the asthmatic patients were disqualified because of inadequate sleep or sleep apnea syndrome. Nineteen of the COPD patients desaturated below a baseline sleep saturation of 90% for 5 min or more, reaching a nadir saturation of at least 85%. We collected arterial samples to measure ET-1 levels, 5 min after the first period of desaturation in each of the 19 desaturators COPD patients. None of the 20 asthmatic patients exhibited oxyhemoglobin desaturation during sleep. Baseline arterial ET-1 levels during the day were significantly higher in "desaturators" COPD patients (2.08+/-0.28 pg/ml) compared to "non-desaturators" COPD patients (1.38+/-0.16 pg/ml) (P<0.001) and to asthmatics (0.7+/-0.85 pg/ml) (P<0.001). ET-1 Levels in normal subjects were 1.221+/-0.02 pg/ml. In "desaturators" COPD patients ET-1 levels during the night, 5 min after the first oxyhemoglobin desaturation, were significantly higher (4.28+/-1.10 pg/ml) compared to those during the day (2.08+/-0.28 pg/ml) (P<0.001). A significant negative correlation was observed between ET-1 levels and degree of desaturation during the day (P=0.005, r=0.632) and during the night (P<0.001, r=0

    Acute ischemia of the corpus callosum (CC) is not a well-known feature in patients with acute hydrocephalus. Herein, we describe a case with acute CC infarction due to another rare entity; transient obstructive hydrocephalus. A 66-year-old male was admitted with sudden onset right-sided hemiparesia. CT demonstrated a hematoma on the left basal ganglia with extension to all ventricles. The following day, the patient's neurological status progressed to coma and developed bilateral pyramidal signs. MRI demonstrated obstructive hydrocephalus and acute diffuse infarction accompanied by elevation of the CC. On the same day there was improvement in his neurological status with significant decrease in ventricular size and complete resolution of the clot in the third ventricle. The mechanism of signal abnormalities is probably related with the neural compression of the CC against the falx. Presumably, the clot causing obstruction in the third ventricle dissolved or decayed by the help of fibrinolytic activity of CSF, which was raised after IVH and caused spontaneous improvement of hydrocephalus. Bilateral neurological symptoms suggest diffuse axonal damage and normalization of the intracranial pressure should be performed on the early onset of clinical detorioration in order to prevent axonal injury.

    2016-04-01

    Conclusion: Vitamin D deficiency was highly prevalent in COPD and bronchial asthma (100% and 50% respectively. Low levels of vitamin D were associated with low FEV1%, frequent exacerbations in patients with COPD and bronchial asthma, and increased COPD severity as assessed by GOLD guidelines. Important statistically significant negative associations between vitamin D level and both asthma control and asthma severity according to GINA classification were also found. Thus it is advised to include vitamin D levels in the routine assessment of patients with bronchial asthma and COPD, as well as studying the importance and clinical impact of oral supplementation of vitamin D in patients with COPD and bronchial asthma should be an important goal of future research.

    Full Text Available Abstract Background To demonstrate the involvement of tobacco smoking in the pathophysiology of lung disease, the responses of pulmonary epithelial cells to cigarette smoke condensate (CSC — the particulate fraction of tobacco smoke — were examined. Methods The human alveolar epithelial cell line A549 and normal human bronchial epithelial cells (NHBEs were exposed to 0.4 μg/ml CSC, a concentration that resulted in >90% cell survival and Results NHBEs exposed to CSC showed increased expression of the inflammatory mediators sICAM-1, IL-1β, IL-8 and GM-CSF, as determined by RT-PCR. CSC-induced IL-1β expression was reduced by PD98059, a blocker of mitogen-actived protein kinase (MAPK kinase (MEK, and by PDTC, a NFκB inhibitor. Analysis of intracellular signaling pathways, using antibodies specific for phosphorylated MAPKs (extracellular signal-regulated kinase [ERK]-1/2, demonstrated an increased level of phosphorylated ERK1/2 with increasing CSC concentration. Nuclear localization of phosphorylated ERK1/2 was seen within 30 min of CSC exposure and was inhibited by PD98059. Increased phosphorylation and nuclear translocation of IκB was also seen after CSC exposure. A549 cells transfected with a luciferase reporter plasmid containing a NFκB-inducible promoter sequence and exposed to CSC (0.4 μg/ml or TNF-α (50 ng/ml had an increased reporter activity of approximately 2-fold for CSC and 3.5-fold for TNF-α relative to untreated controls. Conclusion The acute phase response of NHBEs to cigarette smoke involves activation of both MAPK and NFκB.

    2012-01-01

    To investigate 3 cases of chronic parotitis secondary to an acute bend in Stensen's duct caused by an enlargement of the masseteric space. Three female patients presented with symptoms consistent with obstructive parotitis including glandular swelling and tenderness during meals. A 10-year-old patient had unilateral facial swelling with enlargement of the masseter muscle and mandible later diagnosed as fibrous dysplasia. Salivary endoscopy showed an acute bend in Stensen's duct secondary to a mass effect. The patient's parotid swelling resolved following debulking of the mandibular mass and sialendoscopy with irrigation. Two adult patients with bilateral parotid involvement presented with bilateral masseteric hypertrophy and dental wear facets consistent with bruxism. Salivary endoscopy revealed bilateral kinking of Stensen's duct with jaw closure. Both patients improved symptomatically following nightly bite guard use and ultrasound-guided Botox injections of the masseter muscle and parotid. Obstructive parotitis is rarely caused by an acute masseteric bend. Diagnosis of a kinking Stensen's duct is aided with salivary endoscopy and imaging to determine the precipitating pathology. In the case of masseteric hypertrophy, symptomatic improvement can be achieved with Botox-induced atrophy of masseteric hypertrophy or with surgical reduction for associated fibrous dysplasia.

    INTRODUCTION The management of acute left-sided colonic obstruction still remains a challenging problem despite significant progress. METHODS A literature search was undertaken using PubMed and the Cochrane Library regarding the options in emergency management of left-sided colonic obstruction focusing on outcomes such as mortality, morbidity, long-term prognosis and cost effectiveness. DISCUSSION Colonic stenting is the best option either for palliation or as a bridge to surgery. It reduces morbidity and mortality rate and the need for colostomy formation. Stenting is likely to be cost effective, but data are variable depending on the individual healthcare system. Nevertheless, surgical management remains relevant as colonic stenting has a small rate of failure, and it is not always available. There are various surgical options. One-stage primary resection and anastomosis is the preferred choice for low-risk patients. Intra-operative colonic irrigation has no proven benefit. Subtotal colectomy is useful in cases of proximal bowel damage or synchronous tumours. Hartmann's procedure should be reserved for high-risk patients. Simple colostomy has no role other than for use in very ill patients who are not fit for any other procedure. PMID:18430330

  1. Dynamic innate immune responses of human bronchial epithelial cells to severe acute respiratory syndrome-associated coronavirus infection.

    Full Text Available Human lung epithelial cells are likely among the first targets to encounter invading severe acute respiratory syndrome-associated coronavirus (SARS-CoV. Not only can these cells support the growth of SARS-CoV infection, but they are also capable of secreting inflammatory cytokines to initiate and, eventually, aggravate host innate inflammatory responses, causing detrimental immune-mediated pathology within the lungs. Thus, a comprehensive evaluation of the complex epithelial signaling to SARS-CoV is crucial for paving the way to better understand SARS pathogenesis. Based on microarray-based functional genomics, we report here the global gene response of 2B4 cells, a cloned bronchial epithelial cell line derived from Calu-3 cells. Specifically, we found a temporal and spatial activation of nuclear factor (NFkappaB, activator protein (AP-1, and interferon regulatory factor (IRF-3/7 in infected 2B4 cells at 12-, 24-, and 48-hrs post infection (p.i., resulting in the activation of many antiviral genes, including interferon (IFN-beta, -lambdas, inflammatory mediators, and many IFN-stimulated genes (ISGs. We also showed, for the first time, that IFN-beta and IFN-lambdas were capable of exerting previously unrecognized, non-redundant, and complementary abilities to limit SARS-CoV replication, even though their expression could not be detected in infected 2B4 bronchial epithelial cells until 48 hrs p.i. Collectively, our results highlight the mechanics of the sequential events of antiviral signaling pathway/s triggered by SARS-CoV in bronchial epithelial cells and identify novel cellular targets for future studies, aiming at advancing strategies against SARS.

    The author's experiences is reported on intravascular fibrinolytic therapy with urokinase in acute arterial obstructions. Thirty-eight patients were treated, from 1983 to 1986, for acute thrombosis and/or thromboembolization, 22 of which developed on an atherosclerotic lesion, and 10 on a surgical stenotic by-pass graft. A complete vascular recanalization has been obtained, at the end of the procedure, in 69,4% of the cases, 77,7% had a definite final clinical improvement. The results correspond to the medium statistical of the various casistics analyzed for comparison. Surgery has been performed on 27,7% of the patients. Complication have been observed in 8% of the cases. IAF technique is of greatest value in the treatment of those lesions; better results have been obtained with intra-thrombus injection of the drug (as emphasized by many authors) in association with PTA and surgery. A close cooperation between interventional radiology, vascular surgery and angiology is therefore necessary in this field

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

    The objective of the present work was to search for the tissue and cellular markers of remodeling of bronchial mucosa in the patients with different clinical forms of bronchial asthma (BA). The use of up-to-date morphometric techniques has demonstrated that mild and moderately severe forms of bronchial asthma are accompanied by the development of Th2-immune response associated with increased production of interleukin-4 and marked degranulation of eosinophilic granulocytes resulting in desquamation of epithelium and goblet cell hyperplasia. The severe BA phenotype of "chronic asthma with fixed obstruction" is associated with the development of non-atopic inflammation in the bronchial mucous membrane that manifests itself as the increased concentration of interleukin-8 in bronchial mucosa and its neutrophilic infiltration leading to the development of pronounced subepithelial fibrosis, thickening of the basal membrane, and atrophy of epithelium. Specific structural changes in bronchial mucosa of the patients presenting with BA underlie functional disturbances that cause severe bronchial obstructive syndrome.

  9. Experience of diagnosis of congenital arterial anomaly in a child with bronchial obstruction: clinical case and summary

    Full Text Available Congenital anomalies of the aortic arch are a large group of cardiovascular anomalies. Some of them are isolated; others are associated with congenital heart defects or genetic syndromes. There can be different clinical manifestations of these anomalies — from silent forms (accidentally discovered in the examination to a critical circulatory disturbance, requiring surgical intervention in the first hours after the birth of the baby. The article describes clinical search of double aortic arch in a child and successful surgical treatment of this anomaly. This congenital defect of the aorta usually causes the greatest compression of airways compared to other vascular abnormalities. Double aortic arch develops due to absence of involution of distal IV right aortic arch. As a result, two IV arches keep on developing and join together in the left-sided descending thoracic aorta, thus surrounding the trachea and esophagus. Smaller of the two arches is often subjected to atresia, but it is still connected to the descending aorta, creating a complete vascular ring. As a double aortic arch pressures on the trachea and esophagus, it can cause airway obstruction and dysphagia in a patient. Therapeutic tactic depends on the intensity of symptoms, presence of concomitant anomalies or diseases, and many additional factors, which are analyzed and considered within the council of physicians of different specialties.

    Main treatable Chronic Respiratory Diseases (CRDs) like Chronic Obstructive Pulmonary Disease (COPD), Bronchial Asthma (BA) and Allergic Rhinitis (AR) are underdiagnosed and undertreated worldwide. CORE study was aimed to assess the point prevalence of COPD, BA and AR in the adult population of major cities of Commonwealth of Independent States (CIS) countries - Azerbaijan, Kazakhstan, and Ukraine based on study questionnaires and/or spirometry, and to document risk factors, characterize the COPD, BA and AR population to provide a clearer "epidemiological data". A descriptive, cross-sectional, population-based epidemiological study conducted from 2013 to 2015 with two-stage cluster geographical randomization. Interviewers conducted face-to-face visits at respondent's household after informed consent and eligibility assessment including interviews, anthropometry, spirometry (with bronchodilator test) and completion of disease-specific questionnaires. Two thousand eight hundred forty-two respondents (Ukraine: 964 from Ukraine; 945 from Kazakhstan; 933 Azerbaijan) were enrolled. Mean age was 40-42 years and males were 37%-42% across three countries. In Kazakhstan 62.8% were Asians, but in Ukraine and in Azerbaijan 99.7% and 100.0%, respectively, were Caucasians. Manual labourers constituted 40.5% in Ukraine, 22.8% in Kazakhstan and 22.0% in Azerbaijan, while office workers were 16.1%, 31.6% and 36.8% respectively. 51.3% respondents in Ukraine, 64.9% in Kazakhstan and 69.7% in Azerbaijan were married. CORE study collected information that can be supportive for health policy decision makers in allocating healthcare resources in order to improve diagnosis and management of CRDs. The detailed findings will be described in future publications. Study Protocol Summary is disclosed at GlaxoSmithKline Clinical Study Register on Jun 06, 2013, study ID 116757 .

    The two main sources of blood supply to the lungs and their supporting structures are the pulmonary and bronchial arteries. The bronchial arteries account for 1% of the cardiac output but can be recruited to provide additional systemic circulation to the lungs in various acquired and congenital thoracic disorders. An understanding of bronchial artery anatomy and function is important in the identification of bronchial artery dilatation and anomalies and the formulation of an appropriate differential diagnosis. Visualization of dilated bronchial arteries at imaging should alert the radiologist to obstructive disorders that affect the pulmonary circulation and prompt the exclusion of diseases that produce or are associated with pulmonary artery obstruction, including chronic infectious and/or inflammatory processes, chronic thromboembolic disease, and congenital anomalies of the thorax (eg, proximal interruption of the pulmonary artery). Conotruncal abnormalities, such as pulmonary atresia with ventricular septal defect, are associated with systemic pulmonary supply provided by aortic branches known as major aortopulmonary collaterals, which originate in the region of the bronchial arteries. Bronchial artery malformation is a rare left-to-right or left-to-left shunt characterized by an anomalous connection between a bronchial artery and a pulmonary artery or a pulmonary vein, respectively. Bronchial artery interventions can be used successfully in the treatment of hemoptysis, with a low risk of adverse events. Multidetector computed tomography helps provide a vascular road map for the interventional radiologist before bronchial artery embolization. RSNA, 2015

    With increasing health care costs that have outpaced those of other industries, payers of health care are moving from a fee-for-service payment model to one in which reimbursement is tied to outcomes. Chronic obstructive pulmonary disease (COPD) is a disease where this payment model has been implemented by some payers, and COPD exacerbations are a quality metric that is used. Under an outcomes-based payment model, it is important for health systems to be able to identify patients at risk for poor outcomes so that they can target interventions to improve outcomes. To develop and evaluate predictive models that could be used to identify patients at high risk for COPD exacerbations. This study was retrospective and observational and included COPD patients treated with a bronchodilator-based combination therapy. We used health insurance claims data to obtain demographics, enrollment information, comorbidities, medication use, and health care resource utilization for each patient over a 6-month baseline period. Exacerbations were examined over a 6-month outcome period and included inpatient (primary discharge diagnosis for COPD), outpatient, and emergency department (outpatient/emergency department visits with a COPD diagnosis plus an acute prescription for an antibiotic or corticosteroid within 5 days) exacerbations. The cohort was split into training (75%) and validation (25%) sets. Within the training cohort, stepwise logistic regression models were created to evaluate risk of exacerbations based on factors measured during the baseline period. Models were evaluated using sensitivity, specificity, and positive and negative predictive values. The base model included all confounding or effect modifier covariates. Several other models were explored using different sets of observations and variables to determine the best predictive model. There were 478,772 patients included in the analytic sample, of which 40.5% had exacerbations during the outcome period. Patients with

    Full Text Available Obturator hernia is a rare type of pelvic hernia which generally occurs in elderly patients with accompanying diseases. Because it is difficult to diagnose before surgery, the morbidity and mortality rates for obturator hernia are high. The most common symptom is strangulation combined with mechanical intestinal obstruction.

    Exacerbations constitute a major cause of morbidity and mortality in patients suffering from chronic obstructive pulmonary disease (COPD). Both bacterial infections, such as those with non-typeable Haemophilus influenzae (NTHi), and exposures to diesel engine emissions are known to contribute to exacerbations in COPD patients. However, the effect of diesel exhaust (DE) exposure on the epithelial response to microbial stimulation is incompletely understood, and possible differences in the response to DE of epithelial cells from COPD patients and controls have not been studied. Primary bronchial epithelial cells (PBEC) were obtained from age-matched COPD patients (n = 7) and controls (n = 5). PBEC were cultured at the air-liquid interface (ALI) to achieve mucociliary differentiation. ALI-PBECs were apically exposed for 1 h to a stream of freshly generated whole DE or air. Exposure was followed by 3 h incubation in presence or absence of UV-inactivated NTHi before analysis of epithelial gene expression. DE alone induced an increase in markers of oxidative stress (HMOX1, 50-100-fold) and of the integrated stress response (CHOP, 1.5-2-fold and GADD34, 1.5-fold) in cells from both COPD patients and controls. Exposure of COPD cultures to DE followed by NTHi caused an additive increase in GADD34 expression (up to 3-fold). Importantly, DE caused an inhibition of the NTHi-induced expression of the antimicrobial peptide S100A7, and of the chaperone protein HSP5A/BiP. Our findings show that DE exposure of differentiated primary airway epithelial cells causes activation of the gene expression of HMOX1 and markers of integrated stress response to a similar extent in cells from COPD donors and controls. Furthermore, DE further increased the NTHi-induced expression of GADD34, indicating a possible enhancement of the integrated stress response. DE reduced the NTHi-induced expression of S100A7. These data suggest that DE exposure may cause adverse health effects in part by

    The aim of this study was to evaluate the utility of the iterative reconstruction (IR) technique for quantitative bronchial assessment during low-dose computed tomography (CT) as a substitute for standard-dose CT in patients with/without chronic obstructive pulmonary disease. Fifty patients (mean age, 69.2; mean % predicted FEV1, 79.4) underwent standard-dose CT (150mAs) and low-dose CT (25mAs). Except for tube current, the imaging parameters were identical for both protocols. Standard-dose CT was reconstructed using filtered back-projection (FBP), and low-dose CT was reconstructed using IR and FBP. For quantitative bronchial assessment, the wall area percentage (WA%) of the sub-segmental bronchi and the airway luminal volume percentage (LV%) from the main bronchus to the peripheral bronchi were acquired in each dataset. The correlation and agreement of WA% and LV% between standard-dose CT and both low-dose CTs were statistically evaluated. WA% and LV% between standard-dose CT and both low-dose CTs were significant correlated (r > 0.77, p < 0.00001); however, only the LV% agreement between SD-CT and low-dose CT reconstructed with IR was moderate (concordance correlation coefficient = 0.93); the other agreement was poor (concordance correlation coefficient <0.90). Quantitative bronchial assessment via low-dose CT has potential as a substitute for standard-dose CT by using IR and airway luminal volumetry techniques. circle Quantitative bronchial assessment of COPD using low-dose CT is possible.

    2013-01-01

    Ogilvie's syndrome (OS), a massive dilation of the colon in the absence of mechanical obstruction, is a rare postsurgical complication. The high mortality rate (normally 15 - 31% and upto 45% after caecal perforation) explains the seriousness of this clinical situation. Early diagnosis is made by plain abdominal X-ray and CT abdomen. Conservative treatment is usually effective and surgery should be reserved for complicated cases or refractory to conservative treatment. We report a case of 25 years primigravida who developed OS, 24 hours after cesarean section, which was treated by conservative methods. (author)

    The chronic obstructive pulmonary disease or COPD is a slowly progressive disease whose course is frequently the subject of acute episodes, of variable severity, although, in general, reversible, called acute exacerbations. In the past five years (between 2008 and 2013), seven prognostic scores have been published to try to assess the short-term risk of these acute exacerbations. Their components and characteristics are analysed and commented upon. An Internet program with a detailed compilation of the main features of these scores (www.medhyg.ch/scoredoc) supplements this review.

    Objective: To evaluate the clinical value and safety of combined percutaneous nephrostomy and antegrade double-pigtail stenting with regional intrarterial infusion chemotherapy in the management of acute obstructive renal failure secondary to pelvic primary malignant tumor and metastasis. Methods: Percutaneous unilateral nephrostomy and stenting were done in 18 cases of acute malignant obstructive renal failure due to bilateral ureteral obstruction. Regional TAIs with routine drug dosage were performed after 3 to 5 days of restoration of normal renal function. Results: Seventeen procedures were all successful in the first attempt, except 1 was interrupted due to massive left perirenal hematoma which was controlled by segemental renal arterial embolization with gelform particals and secondary successful PCN was performed in right kidney 5 days later. No other serious complications occurred. The levels of pretreatment serum creatinine were 175.40 μmol/L to 1040.70 μmol/L, with bleeding tendency in 6 cases, and all returned to normal from 2 to 7 days after successful PCN. Follow-up was taken from 3 months to 15 months, averaging 7 months. Conclusion: The combined percutaneous nephrostomy and antegrade double-pigtail stenting with regional intraarterial infusion chemotherapy in the management of acute obstructive renal failure secondary to pelvic malignant tumors is safe, feasible, less complications, providing the prolongation of patient's survival span.

    Cytomegalovirus (CMV) infection causes significant morbidty and mortality in immunopromised patients. Though it is usually silent in immunocompetent adults, rarely it can cause serious life-threatening complications. Gastrointestinal tract is one of the commonly involved organs, where it produces a spectrum of clinical manifestation ranging from mild non-specific abdominal pain and diarrhoea to severe infection with toxic megacolon and death. We present a 65-year-old immunocompetent male patient admitted with acute colonic obstruction secondary to CMV-induced colonic stricture, highlighting the importance of considering it as a differential diagnosis for colonic obstruction and reviewing its management.

    One of the evolutionary complications of hepatic echinococcosis (HE) is cholangiohydatidosis, a rare cause of obstructive jaundice and cholangitis. The aim of this study was to describe the results of surgical treatment on a group of patients with cholangiohydatidosis and secondary cholangitis in terms of post-operative morbidity (POM). Case series of patients operated on for cholangiohydatidosis and cholangitis in the Department at Surgery of the Universidad de La Frontera and the Clínica Mayor in Temuco, Chile between 2004 and 2014. The minimum follow-up time was six months. The principal outcome variable was the development of POM. Other variables of interest were age, sex, cyst diameter, hematocrit, leukocytes, total bilirubin, alkaline phosphatase and transaminases, type of surgery, existence of concomitant evolutionary complications in the cyst, length of hospital stay, need for surgical re-intervention and mortality. Descriptive statistics were calculated. A total of 20 patients were studied characterized by a median age of 53 years, 50.0% female and 20.0% having two or more cysts with a mean diameter of 13.3 ± 6.3 cm. A median hospital stay of six days and follow-up of 34 months was recorded. POM was 30.0%, re-intervention rate was 10.0% and mortality rate was 5.0%. Cholangiohydatidosis is a rare cause of obstructive jaundice and cholangitis associated with significant rates of POM and mortality.

    2007-04-01

    Full Text Available Asthma is one of the main causes of morbidity worldwide. It affects some 300 million individuals and has risen over the past 20 years, especially in the paediatric population. Asthma is a chronic inflammation of the airways, subject to periodic exacerbations, characterised by coughing and progressive dyspnoea. Clinical conditions may vary greatly, ranging from moderate exacerbation with an increase in nocturnal awakening and a less than 20% reduction in the flow peak, through to severe respiratory insufficiency that requires immediate intubation of the airways. Pharmacological treatment envisages a step approach that aims to obtain and maintain control over the symptoms, taking into consideration the effectiveness of the treatment available, potential side effects and cost. β2-agonists and corticosteroids are the drugs of election for both maintenance therapy and for treating exacerbations. Other therapeutic devices may prove useful in particular cases. One fundamental key point in treatment over time is the cooperation between patient and attending doctor. The latest review of the Global Initiative for Asthma (GINA guidelines was published in 2006.

    To compare tulobuterol patch and oral salbutamol sulfate in terms of efficacy and safety in children with mild or moderate acute attack of bronchial asthma. A total of 92 children with mild and moderate acute asthmatic attack were randomly divided into salbutamol group (n=46) and tulobuterol group (n=46). Both groups received routine treatment with antihistamine, selective leukotriene receptor antagonist and glucocorticoid. In addition, the salbutamol group was given slow-release capsules of salbutamol sulfate, and the tulobuterol group was treated with tulobuterol patch. The two groups were compared with respect to symptom scores of cough, wheeze, respiratory rate, wheezing sound, three depression sign and peak expiratory flow, as well as adverse events. As the treatment proceeded, symptom scores decreased in both groups; on the third day of treatment, all symptom scores except cough score showed a significant decrease in both groups (Pattack.

    Acute dysfunction of mechanical aortic valve prostheses is a life-threatening adverse event. Pannus overgrowth, which is fibroelastic hyperplasia originating from the periannular area, is one cause of dysfunction. The aim of this study was to determine the annual incidence of readmittance resulting from acute obstruction caused by pannus during 30 years of observation in patients with Medtronic-Hall aortic valve prostheses and to analyze the risk factors associated with pannus development. From 1982 to 2004, 1,187 patients in our department underwent aortic valve replacement with Medtronic-Hall mechanical monoleaflet valve prostheses. As of December 31, 2012, 27 of these patients (2.3%) had presented with acute valve dysfunction caused by pannus obstruction. The annual incidence of pannus was 0.7 per 1,000. The median time from the primary operation to prosthetic dysfunction was 11.1 years (range, 1.2 to 26.8 years). Of the 20 patients who underwent reoperation, 2 died. Seven patients died before reoperation. Women had a higher risk for the development of obstructing pannus, and patients with pannus obstruction were younger. Valve size was not an independent risk factor. Women and younger patients are at higher risk for pannus development. When acute dysfunction by pannus is suspected in a mechanical aortic valve, an immediate echocardiogram and an emergency aortic valve replacement should be carried out because of the potential of a fatal outcome.

    To evaluate the frequency and contributing factors for acute pancreatitis after endoscopic retrograde cholangio-pancreatography in patients with obstructive jaundice. Study Design: Descriptive case series. Place and Duration of Study: A descriptive case series conducted at department of Gastroenterology, Shaikh Zayed Hospital, Lahore in the period of six months. Material and Methods: Two hundred and thirty patients diagnosed as having obstructive jaundice and undergoing ERCP who fulfilled the inclusion criteria were included in the study from the outpatient and indoor department of Gastroenterology-Hepatology Shaikh Zayed Hospital Lahore. Informed consent was taken. After the selection of the cases, patients were evaluated for the presence or absence of contributing factors like age, gender, cannulation attempts, cannulation time, percutaneous papillotomy, pancreatic duct contrast injection and previous history of post ERCP pancreatitis. Data was analysed by using the statistical software for social sciences (SPSS) version 15. Results: In our study, mean age was 44 +- 14.12 years. Out of 230 patients 42.17% (n=97) were male and 57.83% (n=133) were females. Frequency of acute pancreatitis after ERCP in patients with obstructive jaundice was 4.78% (n=11) while 95.22% (n=219) had no findings of acute pancreatitis after ERCP. Frequency of factors for acute pancreatitis after endoscopic retrograde cholangiopancreatography in patients with obstructive jaundice was recorded which shows that out of 11 cases, 45.45% (n=5) were females, 36.36% (n=4) had previous history of Post ERCP Pancreatitis, 27.27% (n=3) had >5 attempts of cannulation, 36.36% (n=4) had >5 minute time for cannulation, 54.55% (n=6) had pre-cut papillotomy while 63.64% (n=7) had pancreatic duct contrast injection. Conclusion: We concluded that frequency of acute pancreatitis after endoscopic retrograde cholangiopancreatography in patients with obstructive jaundice was found not very high in our practice

    Independently, obstructive sleep apnea (OSA) and infectious mononucleosis are not uncommon in the pediatric population, but acute onset of OSA, as a respiratory complication in the setting of acute EBV infection is extremely uncommon. Previous reports of this clinical entity are sparse and from nearly two decades ago. Urgent adenotonsillectomy was commonly advocated. This complication may be managed medically with systemic corticosteroids and non-invasive continuous positive airway pressure (CPAP), and a case is presented to highlight an updated management approach to this rarely encountered clinical problem in children.

    Acute exacerbation of chronic obstructive pulmonary disease (COPD) is a clinical diagnosis that is based on changes in dyspnea, cough, and/or sputum production in a COPD patient; however, patients presenting with an acute exacerbation may be undiagnosed or have a variety of comorbid conditions that can complicate diagnosis. This issue presents strategies and algorithms for the early use of evidence-based interventions, including appropriate use of antibiotics, bronchodilators, and corticosteroids, along with noninvasive ventilation with capnography, to minimize morbidity and mortality associated with this disease.

    Acute bronchial mucosal sloughing related to Toxic Epidermal Necrolysis (Lyell syndrome) is widely reported in literature. On the contrary severe respiratory involvement is rare in post-infectious or toxic Epitheliolysis (Stevens-Johnson syndrome). There is no well-known predictive sign of bronchial epithelium involvement. An 18-year-old patient was admitted for Stevens-Johnson syndrome related to sulfasalazine (salazosulfapyridine). There were no respiratory signs. An acute respiratory failure occurred 36 hours after from admission due to an obstructive and desquamative necrosis of the tracheobronchial epithelium. We purpose that a fiberoptic laryngoscopy should be performed even in non-dyspneic patients suffering from Stevens-Johnson syndrome if hypersecretion is present. Fiberoptic bronchoscopy can be helpful in these cases.

    2004-01-01

    To evaluate the usefulness of the impedance index of the renal vein for the diagnosis of acute obstructive uropathy in rabbits. Ligation of the left ureter was done in 12 rabbits. Doppler sonography of the interlobar veins in both kidneys was checked before and 30 minutes, 1, 3, 6, 9 and 24 hours after ureteral ligation. The venous impedance index [(peak flow signal-least flow signal)/peak flow signal] was compared between the obstructed and non-obstructed kidneys for all periods. The change in the impedance index after ureteral ligation was also compared between the obstructed and non-obstructed kidneys. A decrease in the impedance index of the intrarenal vein was observed starting from 30 mins atter ureteral ligation, and the index remained low up to 24 hours after ureteral ligation. The obstructed kidneys had a significantly lower impedance index than the contralateral kidneys for all six of the postligation measurements (p< 0.05). There were significant differences in the change of impedance index after ureteral ligation between the obstructed and non-obstructed kidneys (p< 0.05). The impedance index of the intrarenal vein was significantly decreased in the obstructed kidneys. The measurement of the impedance index of the intrarenal vein using Doppler sonography could provide a useful method of diagnosing obstructive uropathy

    Background. Acute intestinal obstruction during pregnancy is a very challenging and unusual nonobstetric surgical entity often linked with considerable fetomaternal morbidity and mortality. When it is synchronous with abdominal pregnancy, it is even rarer. Case Presentation. A 28-year-old lady in her second pregnancy was referred to Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria, at 27 weeks of gestation due to vomiting, constipation, and abdominal pain. Examination and ultrasound scan revealed a single live intra-abdominal extrauterine fetus. Plain abdominal X-ray was diagnostic of intestinal obstruction. Conservative treatment was successful till the 34-week gestational age when she had exploratory laparotomy. At surgery, the amniotic sac was intact and the placenta was found to be adherent to the gut. There was also a live female baby with birth weight of 2.3 kg and Apgar scores of 9 and 10 in the 1st and 5th minutes, respectively, with the baby having right clubbed foot. Adhesiolysis and right adnexectomy were done. The mother and her baby were well and were discharged home nine days postoperatively. Conclusion. To the best of our knowledge, this is the first report of abdominal pregnancy as the cause of acute intestinal obstruction in the published literature. Management approach is multidisciplinary.

    Obstructive sleep apnea (OSA) and dysphagia are common in acute stroke and are both associated with increased risk of complications and worse prognosis. The aims of the present study were (1) to evaluate the prevalence of OSA and dysphagia in patients with acute, first-ever, ischemic stroke; (2) to investigate their clinical correlates; and (3) to verify if these conditions are associated in acute ischemic stroke. We enrolled a cohort of 140 consecutive patients with acute-onset (<48 hours), first-ever ischemic stroke. Computed tomography (CT) and magnetic resonance imaging scans confirmed the diagnosis. Neurological deficit was measured using the National Institutes of Health Stroke Scale (NIHSS) by examiners trained and certified in the use of this scale. Patients underwent a clinical evaluation of dysphagia (Gugging Swallowing Screen) and a cardiorespiratory sleep study to evaluate the presence of OSA. There are 72 patients (51.4%) with obstructive sleep apnea (OSA+), and there are 81 patients (57.8%) with dysphagia (Dys+). OSA+ patients were significantly older (P = .046) and had greater body mass index (BMI) (P = .002), neck circumference (P = .001), presence of diabetes (P = .013), and hypertension (P < .001). Dys+ patients had greater NIHSS (P < .001), lower Alberta Stroke Programme Early CT Score (P < .001), with greater BMI (P = .030). The association of OSA and dysphagia was greater than that expected based on the prevalence of each condition in acute stroke (P < .001). OSA and dysphagia are associated in first-ever, acute ischemic stroke. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

  7. IDIOPATHIC SCLEROSING ENCAPSULATING PERITONITIS CAUSING ACUTE INTESTINAL OBSTRUCTION AND GANGRENE: A CASE REPORT

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available INTRODUCTION Sclerosing encapsulating peritonitis (SEP is a relatively rare cause of intestinal obstruction resulting from encasement of variable lengths of bowel by dense fibro-collagenous membrane. It is more common in young females, and shows tropical and sub-tropical distribution. The idiopathic cases of SEP, which lack any identifiable cause from clinical, radiological and histopathological findings, are also reported under the descriptive term “abdominal cocoon syndrome”. SEP presents with acute or sub-acute intestinal obstruction with or without a mass. In the era of laparoscopic surgery, inadvertent damage to the small bowel at insertion of the trocar and cannula can occur by being unaware of this condition resulting in unnecessary bowel resection. Persistent untreated SEP may advance to bowel gangrene or intestinal perforation, representing life threatening conditions. We report the clinical presentation of a 75-year-old female presenting with signs of intestinal obstruction whose imaging findings revealed abdominal cocoon with bowel gangrene leading to perforation and the same confirmed at surgery. Surgical excision of the fibrotic sac encasing the bowel, resection of gangrenous bowel segment and end ileostomy was performed. Histopathology of the excised membrane confirmed sclerosing encapsulating peritonitis. To our knowledge, only a few cases of abdominal cocoon with perforation have been reported in literature so far. Radiologists should be aware of this relatively rare cause of intestinal obstruction, its imaging findings and complications, as preoperative diagnosis will prevent delay and aid in treatment planning to the surgeon. Identification of soft tissue density membrane encasing congregated small bowel loops into a single area on computed-tomography gives diagnostic clue. Surgical excision of sac, release of bowel loops and adhesions with partial intestinal resection when necessary is the treatment.

  8. Acute appendicitis mimicking intestinal obstruction in a patient with cystic fibrosis

    Full Text Available Cystic fibrosis (CF is an inherited disease of the secretory glands caused by mutations of the cystic fibrosis transmembrane regulator (CFTR gene. The clinical manifestations of CF are repetitive lung infections, biliary cirrhosis, pancreatic abnormalities, and gastrointestinal disorders. We report a 21-year-old Taiwanese man with CF who had abdominal pain for 2 days. The diagnosis of CF had been confirmed by peripheral blood analysis of the CFTR gene 5 years before admission. He presented to the emergency department with nausea, vomiting, abdominal distension, and crampy abdominal pain, which is atypical for acute appendicitis. The physical examination and a series of studies revealed intestinal obstruction, but acute appendicitis could not be ruled out. After conservative treatment, together with empiric antibiotics, the refractory abdominal pain and leukocytosis with a left-shift warranted surgical intervention. A diagnostic laparoscopy revealed a swollen, hyperemic appendix, a severely distended small intestine, and serous ascites. The laparoscopic procedure was converted to a laparotomy for open disimpaction and appendectomy. He was discharged on the eighth postoperative day. The histologic examination of the appendix was consistent with early appendicitis. In conclusion, acute abdominal pain in adult CF patients is often associated with intestinal obstruction syndrome. The presentation of concurrent appendicitis may be indolent and lead not only to diagnostic difficulties, but also a number of therapeutic choices.

We report a 21-year-old Taiwanese man with CF who had abdominal pain for 2 days. The diagnosis of CF had been confirmed by peripheral blood analysis of the CFTR gene 5 years before admission. He presented to the emergency department with nausea, vomiting, abdominal distension, and crampy abdominal pain, which is atypical for acute appendicitis. The physical examination and a series of studies revealed intestinal obstruction, but acute appendicitis could not be ruled out. After conservative treatment, together with empiric antibiotics, the refractory abdominal pain and leukocytosis with a left-shift warranted surgical intervention. A diagnostic laparoscopy revealed a swollen, hyperemic appendix, a severely distended small intestine, and serous ascites. The laparoscopic procedure was converted to a laparotomy for open disimpaction and appendectomy. He was discharged on the eighth postoperative day. The histologic examination of the appendix was consistent with early appendicitis. In conclusion, acute abdominal pain in adult CF patients is often associated with intestinal obstruction syndrome. The presentation of concurrent appendicitis may be indolent and lead not only to diagnostic difficulties, but also a number of therapeutic choices. Copyright © 2012. Published by Elsevier B.V.

    To focus on both positive and negative aspects of the interaction between asthmatic patients and the social networks, and to highlight the need of a psychological approach in some individuals to integrate pharmacological treatment is the purpose of review. There is evidence that in some asthmatic patients, the excessive use of social networks can induce depression and stress triggering bronchial obstruction, whereas in others their rational use can induce beneficial effects in terms of asthma management. The increasing asthma prevalence in developed countries seen at the end of last century has raised concern for the considerable burden of this disease on society as well as individuals. Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social networks by enhancing communication, social connection and self-esteem.

    Full Text Available Objectives: to stratify the risk for obstructive sleep apnea in patients with acute myocardial infarction, treated at a public, tertiary, teaching hospital of the state of São Paulo, Brazil, and to identify related sociodemographic and clinical factors.Method: cross-sectional analytical study with 113 patients (mean age 59.57 years, 70.8% male. A specific questionnaire was used for the sociodemographic and clinical characterization and the Berlin Questionnaire for the stratification of the risk of obstructive sleep apnea syndrome.Results: the prevalence of high risk was 60.2% and the outcome of clinical worsening during hospitalization was more frequent among these patients. The factors related to high risk were body mass index over 30 kg/m2, arterial hypertension and waist circumference indicative of cardiovascular risk, while older age (60 years and over constituted a protective factor.Conclusion: considering the high prevalence of obstructive sleep apnea and its relation to clinical worsening, it is suggested that nurses should monitor, in their clinical practice, people at high risk for this syndrome, guiding control measures of modifiable factors and aiming to prevent the associated complications, including worsening of cardiovascular diseases.

    Intestinal malrotation occurs when there is a disruption in the normal embryological development of the bowel. The majority of patients present with clinical features in childhood, though rarely a first presentation can take place in adulthood. Recurrent bowel obstruction in patients with previous abdominal operation for midgut malrotation is mostly due to adhesions but very few reported cases have been due to recurrent volvulus. We present the case of a 22-year-old gentleman who had laparotomy in childhood for small bowel volvulus and then presented with acute bowel obstruction. Preoperative computerised tomography scan showed small bowel obstruction and features in keeping with midgut malrotation. Emergency laparotomy findings confirmed midgut malrotation with absent appendix, abnormal location of caecum, ascending colon and small bowel. In addition, there were small bowel volvulus and a segment of terminal ileal stricture. Limited right hemicolectomy was performed with excellent postoperative recovery. This case is presented to illustrate a rare occurrence and raise an awareness of the possibility of dreadful recurrent volvulus even several years following an initial Ladd's procedure for midgut malrotation. Therefore, one will need to exercise a high index of suspicion and this becomes very crucial in order to ensure prompt surgical intervention and thereby preventing an attendant bowel ischaemia with its associated high fatality.

    Noninvasive ventilation (NIV) with conventional therapy improves the outcome of patients with acute respiratory failure due to hypercapnic decompensation of chronic obstructive pulmonary disease (COPD) or acute cardiogenic pulmonary edema (ACPE). This review summarizes the main effects of NIV in these pathologies. In COPD, NIV improves gas exchange and symptoms, reducing the need for endotracheal intubation, hospital mortality and hospital stay compared with conventional oxygen therapy. NIV may also avoid reintubation and may decrease the length of invasive mechanical ventilation. In ACPE, NIV accelerates the remission of symptoms and the normalization of blood gas parameters, reduces the need for endotracheal intubation, and is associated with a trend towards lesser mortality, without increasing the incidence of myocardial infarction. The ventilation modality used in ACPE does not affect the patient prognosis. Copyright © 2012 Elsevier España, S.L. y SEMICYUC. All rights reserved.

    Intestinal pseudoobstruction is a clinical syndrome characterized by impairment of intestinal propulsion, which may resemble intestinal obstruction, in the absence of a mechanical cause. It usually affects the colon but the small intestine may also be involved, and may present in acute, subacute or chronic forms. We have performed a systematic review of the acute form of pseudoobstruction, also referred to as Ogilvie's syndrome. We discuss proposed pathophysiological mechanisms, manifestations and management of this clinical condition in post-surgery and critically ill patients. The hallmark of the syndrome is massive intestinal distension, which is detected on clinical inspection and plain abdominal radiography. The underlying pathophysiological mechanisms are not fully understood. Therefore, treatment has focussed on preventing intestinal perforation, which is associated with a 21% mortality rate.

    Full Text Available Alcohol ingestion–related increased left ventricular outflow tract (LVOT pressure gradient in hypertrophic obstructive cardiomyopathy (HOCM has been reported in the literature; however, acute myocardial infarction (AMI after alcohol drinking in this patient group is rarely reported. Herein, we report a 68-year-old man with chronic alcoholism suffering from AMI after alcohol drinking. Electrocardiography revealed complete left bundle branch block, and chest X-ray showed acute pulmonary edema. Intubation was done for respiratory failure and intra-aortic balloon pump was also inserted for unstable hemodynamics. However, emergent coronary angiography revealed normal coronary arteries. HOCM was diagnosed by a high pressure gradient over LVOT and systolic anterior motion of mitral valve by echocardiography. This patient became stable under intensive care and medical treatment. This case reminds physicians that alcohol ingestion might cause AMI in HOCM patients because of increased LVOT pressure gradient and decreased coronary perfusion despite normal coronary arteries.

Each of the latter group was imaged with Gd-DTPA enhanced dynamic MR 2, 6, 24, and 48 hours after ligation of the left proximal urter, respectively. We compared the findings of dynamic MR imaging and histopathological findings. We could observe centripetal movement of dark band pattern which could be defined as 3 phases renal cortex, outer medulla, and inner medulla in normal rabbits. The appearance of the dark band pattern was delayed or absent in ureteral obstruction group with linear relationship to the duration of the obstruction. Gd-DTPA enhanced MR can be used to differentiate acute obstructive nephropathy from other causes of nephropathy and foretell the prognosis of the obstruction.

    Severe bronchial obstruction due to one of the major pulmonary diseases: asthma, COPD, or emphysema often requires mechanical ventilation support. Otherwise, patients are at risk of severe hypooxygenation with consecutive overloading and dilatation of the right cardiac ventricle with subsequent failure. This review focuses on how to manage a calculated ventilation therapy of patients suffering from bronchial obstruction and relevant patents. Options and pitfalls of invasive and non-invasive ventilation in the intensive care setting regarding clinical improvement and final outcome are discussed. The non-invasive ventilation is very efficient in treating acute or chronic respiratory failure in COPD patients and is capable of shortening the duration of hospitalization. Further non-invasive ventilation can successfully support the weaning after a long-lasting ventilation therapy and improve the prognosis of COPD patients. "Permissive hypercapnia" is unequivocally established in invasive ventilation therapy of severe bronchial obstruction in situations of limited ventilation. When intrinsic positive end-expiratory pressure (PEEP) and elevated airways resistance are present PEEP may be useful although external-PEEP application relieves over-inflation only in selected patients with airway obstruction during controlled mechanical ventilation. Upper limit of airways peak pressure used in "protective ventilation" of adult respiratory distress syndrome (ARDS) patients can be exceeded under certain circumstances.

    Asthma is defined as a chronic inflammatory airway disease in response to a wide variety of provoking stimuli. Characteristic clinical symptoms of asthma are bronchial hyperreactivity, reversible airway obstruction, wheezing and dyspnea. Asthma presents a major public health problem with increasing prevalence rates and severity worldwide. Despite major advances in our understanding of the clinical management of asthmatic patients, it remains a challenging population for anesthesiologists in clinical practice. The anesthesiologist's responsibility starts with the preoperative assessment and evaluation of the pulmonary function. For patients with asthma who currently have no symptoms, the risk of perioperative respiratory complications is extremely low. Therefore, pulmonary function should be optimized preoperatively and airway obstruction should be controlled by using steroids and bronchodilators. Preoperative spirometry is a simple means of assessing presence and severity of airway obstruction as well as the degree of reversibility in response to bronchodilator therapy. An increase of 15% in FEV1 is considered clinically significant. Most asymptomatic persons with asthma can safely undergo general anesthesia with and without endotracheal intubation. Volatile anesthetics are still recommended for general anesthetic techniques. As compared to barbiturates and even ketamine, propofol is considered to be the agent of choice for induction of anesthesia in asthmatics. The use of regional anesthesia does not reduce perioperative respiratory complications in asymptomatic asthmatics, whereas it is advantageous in symptomatic patients. Pregnant asthmatic and parturients undergoing anesthesia are at increased risk, especially if regional anesthetic techniques are not suitable and prostaglandin and its derivates are administered for abortion or operative delivery. Bronchial hyperreactivity associated with asthma is an important risk factor of perioperative bronchospasm. The

    Full Text Available Abstract Background Apical ballooning syndrome (or Takotsubo cardiomyopathy is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an acute myocardial infarction but is characterised by the absence of obstructive coronary disease. We describe a serious and poorly understood complication of Takotsubo cardiomyopathy. Case Presentation We present the case of a 65 year-old lady referred to us from a rural hospital where she was treated with thrombolytic therapy for a presumed acute anterior myocardial infarction. Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. Echocardiogram revealed severe mitral regurgitation, left ventricular apical ballooning, and systolic anterior motion of the mitral valve with significant left ventricular outflow tract gradient (60–70 mmHg. Coronary angiography revealed no obstructive coronary lesions. She had an intra-aortic balloon pump inserted with no improvement in her parlous haemodynamic state. We elected to replace her mitral valve to correct the outflow tract gradient and mitral regurgitation. Intra-operatively the mitral valve was mildly myxomatous but there were no structural abnormalities. She had a mechanical mitral valve replacement with a 29 mm St Jude valve. Post-operatively, her left ventricular outflow obstruction resolved and ventricular function returned to normal over the subsequent 10 days. She recovered well. Conclusion This case represents a serious and poorly understood association of Takotsubo cardiomyopathy with acute pulmonary oedema, severe mitral regurgitaton and systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction.

    Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

    Obstructive uropathy caused by kidney stones is quite rare in transplant kidneys. The authors report the case of a patient, previously gastrectomized for gastric carcinoma. He underwent renal transplantation using uretero-ureterostomy, and presented an episode of acute renal failure 7 years after surgery. Ultrasound (US) examination showed no sign of rejection but allowed detection of moderate hydronephrosis in the transplant kidney. Subsequent computed tomography (CT) revealed a kidney stone in the middle ureter at the crossing of the iliac vessels. The patient therefore urgently underwent percutaneous nephrostomy of the graft and recovered diuresis and renal function. The patient was transferred to the Transplant Center where he underwent ureterotomy with removal of the stone and subsequent ureteropyelostomy. Also transureteral resection of the prostate (TURP) was performed due to urinary retention of prostatic origin. Histological examination showed prostate carcinoma, Gleason stage 3, which was treated conservatively using radiotherapy without suspension of the administered low dose of immunotherapy. Calculosis is one of the least common causes of obstructive uropathy in transplant kidneys. In the described case, US examination performed after onset of renal insufficiency led to subsequent radiological investigation and resulting interventional procedures (nephrostomy and surgical removal of the stone) with complete recovery of pre-existing renal function.

    A 47-year-old female patient had a subclinical superior vena caval syndrome which developed into the \\'full blown\\' acute condition when she was placed into the left lateral position after mediastinoscopy. She developed airway obstruction requiring urgent re-intubation and subsequent admission to the intensive care unit. This subclinical condition might have been suspected pre-operatively if closer attention had been paid to the history, physical examination and review of the computerised axial tomography scan: she had a history of intermittent dysponea, wheeze and cough which was worse on waking and improved as the day progressed, she had a positive Pemberton\\'s sign and the computerised axial tomography scan showed that the lesion was encroaching on the superior vena cava.

    The aim of this study is to improve the results of surgical treatment of acute bowel obstruction caused by rectal cancer and to reduce the period of full recovery of patients. The presented research included 73 patients (study group) with rectal cancer who underwent emergent anterior resection of rectum with loop ileostomy and intra-operative decompression of colon. Patients of this group were compared to a group of 68 patients (control group) with the same diagnosis who underwent Hartmann's procedure. There was no essential difference between the two groups in the quantity of postoperative complications. However the results indicate significant difference in reversal rates and time to reversal. Thus, the technique of low anterior resection with intraoperative decompression and ileostomy that we used improves outcomes, significantly reduces the period of full recovery.

    2018-04-01

    Acute exacerbation(s) of chronic obstructive pulmonary disease (AECOPD) tend to be critical and debilitating events leading to poorer outcomes in relation to chronic obstructive pulmonary disease (COPD) treatment modalities, and contribute to a higher and earlier mortality rate in COPD patients. Besides pro-active preventative measures intended to obviate acquisition of AECOPD, early recovery from severe AECOPD is an important issue in determining the long-term prognosis of patients diagnosed with COPD. Updated GOLD guidelines and recently published American Thoracic Society/European Respiratory Society clinical recommendations emphasize the importance of use of pharmacologic treatment including bronchodilators, systemic steroids and/or antibiotics. As a non-pharmacologic strategy to combat the effects of AECOPD, noninvasive ventilation (NIV) is recommended as the treatment of choice as this therapy is thought to be most effective in reducing intubation risk in patients diagnosed with AECOPD with acute respiratory failure. Recently, a few adjunctive modalities, including NIV with helmet and helium-oxygen mixture, have been tried in cases of AECOPD with respiratory failure. As yet, insufficient documentation exists to permit recommendation of this therapy without qualification. Although there are too few findings, as yet, to allow for regular andr routine application of those modalities in AECOPD, there is anecdotal evidence to indicate both mechanical and physiological benefits connected with this therapy. High-flow nasal cannula oxygen therapy is another supportive strategy which serves to improve the symptoms of hypoxic respiratory failure. The therapy also produced improvement in ventilatory variables, and it may be successfully applied in cases of hypercapnic respiratory failure. Extracorporeal carbon dioxide removal has been successfully attempted in cases of adult respiratory distress syndrome, with protective hypercapnic ventilatory strategy. Nowadays, it is

The role of dynamic hyperinflation during exacerbations is unclear. Methods: In a prospective, observational cohort study, we recruited patients admitted to hospital for AECOPD. The following measurements were performed upon admission and again after resolution (stable state at least 42 days later: inspiratory capacity (IC, body plethysmography, dynamic hyperinflation by metronome-paced IC measurement, health-related quality of life and dyspnea. Results: Forty COPD patients were included of whom 28 attended follow-up. The IC was low at admission (2.05±0.11 L and increased again during resolution by 15.6%±23.1% or 0.28±0.08 L (mean ± standard error of the mean, p<0.01. Testing of metronome-paced changes in IC was feasible, and it decreased by 0.74±0.06 L at admission, similarly to at stable state. Clinical COPD Questionnaire score was 3.7±0.2 at admission and improved by 1.7±0.2 points (p<0.01, and the Borg dyspnea score improved by 2.2±0.5 points from 4.4±0.4 at admission (p<0.01. Conclusion: Static hyperinflation is increased during severe AECOPD requiring hospitalization compared with stable state. We could measure metronome-paced dynamic hyperinflation during severe AECOPD but found no increase.

The objective of the present study was to determine the frequency and clinical relevance of HBoV infection in adult patients with acute exacerbation of chronic obstructive pulmonary disease (AE-COPD.Methods: We retrospectively tested 212 COPD patients, 141 (66.5% with AE-COPD and 71 (33.5% with stable disease, of whom nasal lavage and induced sputum had been obtained for the presence of HBoV deoxyribonucleic acid (DNA. The specificity of positive polymerase chain reaction results was confirmed by sequencing.Results: Two hundred two of 212 patients for whom PCR results were available both for nasal lavage and induced sputum samples were eligible for data analysis. HBoV DNA was detected in three patients (1.5%. Of those, only one patient had AE-COPD. Thus, the frequency of HBoV infection demonstrated to be low in both AE-COPD (0.8% and stable COPD (2.9%. HBoV was found in two sputum and one nasal lavage sample in different patients, respectively. Sequencing revealed >99% sequence identity with the reference strain.Conclusion: HBoV detection was infrequent. Since we detected HBoV in both upper and lower respiratory tract specimens and in AE-COPD as well as stable disease, a major role of HBoV infection in adults with AE-COPD is unlikely

    Until now, it is unknown whether and to what extent arteriosclerotic disease affects the bronchial arteries. We conducted this pilot study to estimate the prevalence of arteriosclerosis of the bronchial arteries, to correlate it with certain clinicolaboratory arteriosclerotic parameters or any coexistent coronary artery disease (CAD) and to validate the clinical significance. Bronchial arteries 10-15 mm long were obtained from 40 patients with a mean age of 62.3 years who underwent major thoracic procedures. Their medical history and detailed clinical and laboratory arteriosclerotic risk factors were documented. The mean diameter of bronchial artery specimens was 0.97 mm. Histology revealed medial calcific sclerosis only in 1 patient (2.5%) without simultaneous, established atherosclerotic lesions or narrowing of the lumen. Furthermore, the vessel diameter was significantly correlated not only with the advanced stage of the disease (p = 0.031), but also with the proximal occlusion of the bronchial tree (p = 0.042). We noted a marginally not significant correlation between arteriosclerosis and metabolic syndrome (p = 0.075), independent from a history of CAD (p = 0.84). Bronchial arteries exhibit only medial calcific sclerosis. CAD and chronic obstructive pulmonary disease do not seem to affect them in terms of atherosclerotic alteration findings or vessel diameter changes. The bronchial resistance to arteriosclerosis might support the mediastinal status quo through their anastomoses, contributing to all its structures, and might be indirect evidence of a different physiological function of the bronchial endothelium, which needs to be further investigated.

    Purpose: Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002. Materials and methods: From October 1997 to September 2002 we studied six patients affected by pseudo-obstruction of the colon. The pseudo-obstruction was recurrent in two cases. Acute dilatation of the colon without radiologically-detectable organic obstruction was the inclusion criterion for the study. Results: Plain abdominal radiography revealed colon dilatation that extended to the splenic flexure in three patients, to the hepatic flexure in two patients, and confined to the transverse colon in one patient. None of the patients showed air-fluid levels of the small intestine. Conclusion: The most relevant clinical finding in Ogilvie's syndrome is abdominal distension, which arises suddenly, has a progressive course and reaches massive levels. The first-line diagnostic investigation is plain abdominal radiography which shows extreme colon dilatation without air-fluid levels of the small intestine. In three of our patients, conservative therapy alone was able to restore normal conditions within five days; two patients required decompressive colonoscopy, and one patient died from cardio-circulatory arrest after 48 hours [it

    Obstructive sleep apnea (OSA) is frequent in acute stroke patients, and has been associated with higher mortality and worse prognosis. Polysomnography (PSG) is the gold standard diagnostic method for OSA, but it is impracticable as a routine for all acute stroke patients. We evaluated the accuracy of two OSA screening tools, the Berlin Questionnaire (BQ), and the Epworth Sleepiness Scale (ESS) when administered to relatives of acute stroke patients; we also compared these tools against a combined screening score (SOS score). Ischemic stroke patients were submitted to a full PSG at the first night after onset of symptoms. OSA severity was measured by apnea-hypopnea index (AHI). BQ and ESS were administered to relatives of stroke patients before the PSG and compared to SOS score for accuracy and C-statistics. We prospectively studied 39 patients. OSA (AHI ≥10/h) was present in 76.9%. The SOS score [area under the curve (AUC): 0.812; P = 0.005] and ESS (AUC: 0.789; P = 0.009) had good predictive value for OSA. The SOS score was the only tool with significant predictive value (AUC: 0.686; P = 0.048) for severe OSA (AHI ≥30/h), when compared to ESS (P = 0.119) and BQ (P = 0.191). The threshold of SOS ≤10 showed high sensitivity (90%) and negative predictive value (96.2%) for OSA; SOS ≥20 showed high specificity (100%) and positive predictive value (92.5%) for severe OSA. The SOS score administered to relatives of stroke patients is a useful tool to screen for OSA and may decrease the need for PSG in acute stroke setting. Copyright © 2014 Elsevier B.V.

    There are limited data on the epidemiology of acute respiratory failure necessitating mechanical ventilation in patients with severe chronic obstructive pulmonary disease (COPD). The prognosis of acute respiratory failure requiring invasive mechanical ventilation is believed to be grim in this population. The purpose of this study was to illustrate the epidemiologic characteristics and outcomes of patients with underlying severe COPD requiring mechanical ventilation.A retrospective study of patients admitted to a quaternary referral medical intensive care unit (ICU) between January 2008 and December 2012 with a diagnosis of severe COPD and requiring invasive mechanical ventilation for acute respiratory failure.We evaluated 670 patients with an established diagnosis of severe COPD requiring mechanical ventilation for acute respiratory failure of whom 47% were male with a mean age of 63.7 ± 12.4 years and Acute physiology and chronic health evaluation (APACHE) III score of 76.3 ± 27.2. Only seventy-nine (12%) were admitted with a COPD exacerbation, 27(4%) had acute respiratory distress syndrome (ARDS), 78 (12%) had pneumonia, 78 (12%) had sepsis, and 312 (47%) had other causes of respiratory failure, including pulmonary embolism, pneumothorax, etc. Eighteen percent of the patients received a trial of noninvasive positive pressure ventilation. The median duration of mechanical ventilation was 3 days (interquartile range IQR 2-7); the median duration for ICU length of stay (LOS) was 5 (IQR 2-9) days and the median duration of hospital LOS was 12 (IQR 7-22) days. The overall ICU mortality was 25%. Patients with COPD exacerbation had a shorter median duration of mechanical ventilation (2 vs 4 days; P = .04), ICU (3 vs 5 days; P = .01), and hospital stay (10 vs 13 days; P = .01). The ICU mortality (9% vs 27%; P respiratory failure. A 1-unit increase in the APACHE III score was associated with a 1% decrease and having an active cancer was associated

    Full Text Available Objective To investigate the use of enteral immune nutrition preparation in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD, regard its efficacy in improving nutritional status, and its influence on immunity and the status of acute inflammatory reaction of the patients. Methods Sixty-two AECOPD patients requiring mechanical ventilation in ICU of our hospital were randomly divided into two groups: immune nutrition group [study group, n=32, receiving Ruineng (a product of Huarui Pharmaceutical Ltd., which contained essential fatty acids, Omega-3 fatty acids, and energy 1.3 kcal/ml] and conventional nutrition group (control group, n=30, receiving the hospital self-made homogenized diet with 1.2 kal/ml. Patients in the two groups took enteral nutrition of equal calorie, and it was given by nasointestinal tube. On the day of admission and the 14th and 18th after admission, venous blood was obtained for the determination of serum albumin, prealbumin, transferrin, C reactive protein (CRP, tumor necrosis factor-α (TNF-α, and interleukin-6 (IL-6. At the same time upper arm muscle circumference (MAMC was measured at the bed side. The 14-day off-respirator rate and mechanical ventilation time within 28 days were compared between the two groups. Results The 14-day off-respirator rate was higher in study group than in control group (P0.05. Conclusions Compared with homogenized diet, immune enteral nutrition could better improve the nutritional status and immune function, lower the acute inflammatory response level, increase the success rate of early off-respirator in AECOPD patients, therefore, enteral immune nutrition preparation is a better nutrition support solution for AECOPD.

    Acute primary resection as treatment for left-sided colonic obstruction (LSCO) is notorious for its high morbidity and mortality rates. Both stenting and loop colostomy construction can serve as a bridge to surgery, hereby avoiding the high morbidity and mortality rates associated with emergency resections. This study aims to investigate the safety of a loop colostomy in patients presenting with acute LSCO. Retrospective analysis of all patients that received a loop colostomy for LSCO between 2003 and 2015 was performed. Primary outcomes were mortality, major morbidity (Clavien-Dindo grades III-IV) and minor morbidity (Clavien-Dindo grades I-II). One hundred forty-six patients presenting with acute LSCO received a diverting colostomy. After colostomy construction, mortality occurred in four patients (2.7%) and major complications were reported in 20 patients (13.7%). In 61 patients, the diverting colostomy served as a palliative measure, because of metastatic disease or unfitness for major surgery. The remaining 85 patients all underwent delayed resection, resulting in an overall mortality, major morbidity and minor morbidity of 6.9% (n = 6), 14.0% (n = 12) and 26.7% (n = 23), respectively. Diverting colostomy construction is a minimally invasive and safe treatment option for LSCO. It can serve as a definite palliative measure, as well as a bridge to elective surgery. A diverting colostomy as a bridge to surgery might even be a valid alternative for emergency resections, since mortality and morbidity rates following colostomy construction and delayed resection appear lower than reported outcomes following primary resection.

    The acute surgical unit (ASU) is a recently established model of care in Australasia and worldwide. Limited data are available regarding its effect on the management of small bowel obstruction. We compared the management of small bowel obstruction before and after introduction of ASU at a major tertiary referral centre. We hypothesized that introduction of ASU would correlate with improved patient outcomes. A retrospective review of prospectively maintained databases was performed over two separate 2-year periods, before and after the introduction of ASU. Data collected included demographics, co-morbidity status, use of water-soluble contrast agent and computed tomography. Outcome measures included surgical intervention, time to surgery, hospital length of stay, complications, 30-day readmissions, use of total parenteral nutrition, intensive care unit admissions and overall mortality. Total emergency admissions to the ASU increased from 2640 to 4575 between the two time periods. A total of 481 cases were identified (225 prior and 256 after introduction of ASU). Mortality decreased from 5.8% to 2.0% (P = 0.03), which remained significant after controlling for confounders with multivariate analysis (odds ratio = 0.24, 95% confidence interval 0.08-0.73, P = 0.012). The proportion of surgically managed patients increased (20.9% versus 32.0%, P = 0.003) and more operations were performed within 5 days from presentation (76.6% versus 91.5%, P = 0.02). Fewer patients received water-soluble contrast agent (27.1% versus 18.4%, P = 0.02), but more patients were investigated with a computed tomography (70.7% versus 79.7%, P = 0.02). The ASU model of care resulted in decreased mortality, shorter time to intervention and increased surgical management. Overall complications rate and length of stay did not change. © 2015 Royal Australasian College of Surgeons.

    Full Text Available Background: To describe the aetiological and prognostic aspects of acute mechanical intestinal obstruction (AMIO in children at Zinder National Hospital (Niger. Materials and Methods: This was a cross-sectional study on a period to January 2013–June 2015. The database included all children under 15 years of age with a surgical diagnosis of mechanical intestinal obstruction. P < 0.05 was considered statistically significant for analysis. Results: AMIOs represent 21.78% (n = 78 of child digestive surgical emergencies (n = 358. Median age was 12 months (range: 1 day–15 years. Fifteen (19.23% were neonates and sixty children (76.92% had ≤60 months. The sex ratio (male/female was 2.8. The mean time from onset to presentation was 39.96 ± 36.22 h. Intussusception and strangulated hernias were the main causes of AMIO with, respectively, 43.59% (n = 34 and 29.48% (n = 23. Anorectal malformations represent 17.95% (n = 14 of cases of AMIO. Intestinal resection was made in 22.08% and colostomy in 19.23% of patients. The average length of hospital stay was 6.44 ± 4.30 days. The post-operative complications were recorded in 26 patients (33.33%, mostly surgical site infections. Overall mortality of AMIO was 15.38% (n = 12. It was higher in the neonates (33.33% (P = 0.032. Deaths were associated with delay of admission (P = 0.0005 and waiting time for surgery (P = 0.019. Conclusion: Intussusception and strangulated hernia are the most common cause of AMIO in children. Diagnostic and therapeutic delays, lack of paediatric intensive care and post-operative complications are prognostic factors.

    In 97 patients with bronchitis, bronchial asthma, tuberculosis, sarcoidosis, pneumoconiosis, or tumors the mucociliary clearance and/or deposit pattern after inhalation of radioactively marked aerosols (1 mCi 99m Tc sulfur colloid) was studied. Normal values of the mucociliary 30 min. clearance for the central bronchial/lung periphery are 21%/15%. There was a decreased clearance with bronchitis (11/8%), bronchial asthma, emphysema, tuberculosis, sarcoidosis, trachiobronchial amyloidosis, pleural scarring or interstitial pneumona. Increased clearance (29/19%) was shown with pneumoconiosis. The correlation of deposit pattern and disease, for example, bronchitis, bronchial asthma, bullous emphysema, pleural scarring, partial lung resection, bronchopneumonia, or bronchial restriction, is described. In comparison of aerosol scintigraphy to perfusion scintigraphy and ventilation with gaseous xenon, the aerosol scintigraphy is superior to xenon for certain indications. The aerosol particles, which are larger in comparison to xenon, settle easier by obstructions or flow variations and thereby give better clinical indications of regional differences. (orig.) [de

    Objective: To prospectively evaluate the safety and clinical efficacy of a newly designed self-expandable metallic stent (SEMS) placement in the treatment of patients with acute malignant colorectal obstruction due to colorectal carcinomas. Methods: During the period from April 2001 to October 2007, a total of 52 patients with acute malignant colorectal obstruction were treated with stent placement by using a new designed SEMS, which was employed as a preoperative transit means. All the patients were followed up and the relevant data, including technical success rate, clinical efficacy, complications and overall survival rate, were documented. The results were analyzed. Results: Stent placement was successfully carried out in all patients except for two patients who showed complete colorectal obstruction. No procedure-related complications occurred. Technical success rate was 96% (50/52). Two days after the treatment, the relief rate of colorectal obstruction was 98% (49/50). Postoperative complications included stent migration (n=4), anal pain (n=2) and stool impaction (n=1). The stool impaction seen in one patient was successfully removed away with endoscopic manipulation two days after stent placement. An elective one-stage surgical procedure was performed in all 50 patients who successfully received a SEMS placement within a mean interval of (8±2) days (ranged 4-11 days) after stent placement. Mean follow-up time was (36±12) months with a range of (3-70) months. All patients remained alive at the time of this report. Conclusion: The newly designed SEMS placement used as a preoperative transit means is a safe and effective intervention for colonic decompression in patients with acute malignant colorectal obstruction due to colorectal carcinomas. It can reliably ensure most of patients with colorectal carcinomas to successfully accomplish an elective surgery. (authors)

Methods: Between April 2001 and October 2007, 52 patients with acute malignant colorectal obstruction were treated with a new designed SEMS as an investigational bridge to surgery. Patients were prospectively followed and relevant data collection was collected, including details regarding technique, clinical symptoms, complications, need for elective surgery, and overall survival. Results: Stent placement was technically successful in all but two patients (due to complete obstruction) with no procedure-related complications. Complications included stent migration (n = 4), anal pain (n = 2) and stool impaction (n = 1). Clinical success was achieved in 49 (98%) of 50 patients with resolution of bowel obstruction within 2 days of stent placement. In one patient with stool impaction 2 days after stent placement, endoscopic disimpaction was successfully performed. An elective one-stage surgical procedure was performed in all 50 patients who successfully received a SEMS as a bridge to surgery within a mean of 8 ± 2 days (range: 4-11 days) after stent placement. Mean follow-up time was 36 ± 12 months (range 3-70 months), and all patients remained alive at the time of this report. Conclusion: The newly designed SEMS placement as a bridge to surgery was a safe and effective intervention for colonic decompression in patients with acute malignant colorectal obstruction and allowed a high proportion of patients to be successfully proceeded to elective surgery.

    Self-expandable metal stents (SEMSs) have been used as palliative treatment or bridge to surgery for obstructions caused by colorectal cancer (CRC). We assessed the long-term outcomes of palliative SEMSs and evaluated the risk factors influencing complications. One hundred and seventy-five patients underwent SEMS placement for acute malignant colorectal obstruction. Of the 72 patients who underwent palliative treatment for primary CRC, 30 patients received chemotherapy (CT) for primary cancer (CT group) and 42 underwent best supportive treatment (BST) without CT (BST group). There was a significant difference in late migration between the CT group and the BST group (20.0% in CT group, 2.4% in BST group, p = 0.018). Response to CT influenced the rate of late obstruction (0% in disease control, 35.7% in disease progression, p = 0.014). However, late obstruction was not associated with stent properties, such as diameter or type (≤22 mm vs. >22 mm, 13.5% vs. 14.3%, p = 1.00; uncovered stent vs. covered stent, 15.5% vs. 7.1%, p = 0.675) and migration (≤22 mm vs. >22 mm, 16.2% vs. 2.9%, p = 0.108; uncovered stent vs. covered stent, 8.6% vs. 14.3%, p = 0.615) in palliative SEMS. The administration of CT increases the rate of stent migration, and disease control by CT can reduce the risk of obstruction by maintaining the luminal patency of palliative SEMSs.

    Objective: To research the degression of renal function of 99 Tc m -diethylene triamine pentaaceticacid ( 99 Tc m -DTPA) renal imaging in rabbits with acute upper urinary tract obstruction and its early recovery after relief. Methods: Twenty-four health rabbit models with left acute upper urinary tract obstruction were built up. 99 Tc m -DTPA renal imaging was performed before making model and after obstruction 1, 3, 5-7 and more than 8 weeks respectively and 4 weeks after relief of obstruction. Results: After obstnrction 1 and 3 weeks, 99 Tc m -DTPA imaging showed development in left renal. Values of glomemlar filtration rate (GFR) and uptake ratio decreased, while time to reach the peak increased. These are obviously different compared with those before obstruction (t=2.916, t=7.034, P 99 Tc m -DTPA imagingshowed cortex developert. Values of GFR and uptake ratio decreased obvious, while time to reach the peak increased obviously. These are obviously different compared with those before obstruction (t=6.722, t=7.470, t=3.678, P 99 Tc m -DTPA imaging showed no obvious development. In those rabbits with durations of 1-3 weeks obstructions, the renal function could almost recover within 4 weeks after relief of obstruction. GRF is 31.23 ± 14.4 (t=2.627, P 0.05). With obstruction of 5-7 weeks, the GRF and uptake ratio, could recover partly to some extent. But with obstruction for more than 8 weeks, the renal function could not recover. Conclusions: For the acute upper urinary tract obstruction, the renal function is most remarkable decreased in the early time, and can be restored after lelief. For long time obstruction, even if relieved, the renal function is not easily to restore. The dynamic renal imaging can reflect the extent of the renal damage and its recovery, and could be used as a reliable indicator. (authors)

    Full Text Available Purpose: The present study aimed at clinical and pulmonary functions profiling of patients with chronic obstructive pulmonary disease (COPD to anticipate future exacerbations. Methods: The study included 80 COPD patients; 40 patients had ≥2 acute exacerbations during preceding 1 year (frequent exacerbation [FECOPD] group and 40 patients had <2 acute exacerbations during preceding 1 year (infrequent exacerbation [I-FECOPD] group. Clinical profile, sputum microbiology, blood gas analysis, spirometric indices, and diffusion capacity (transfer test variables were assessed. Groups' comparison was performed using an independent t-test for numeric scale parameters and Chi-square test for nominal parameters. Pearson's and Spearman's correlation coefficients were derived for numeric scale parameters and numeric nominal parameters, respectively. Multinomial logistic regression analysis was done using SPSS software. Results: FECOPD group contained younger patients than in I-FECOPD group although the difference was not statistically significant. There was no significant difference between two groups regarding smoking pack-years and duration of illness. FECOPD group had significantly more expectoration score and Modified Medical Research Council dyspnea scores. Cough score and wheeze score did not differ significantly between two groups. More patients in FECOPD group (12/40 vs. 4/40 had lower airway bacterial colonization. Arterial blood gas parameters were more deranged in FECOPD group. Spirometric indices (forced expiratory volume during 1st s as well as transfer test (both diffusing capacity for carbon monoxide and transfer coefficient of the lung values were significantly reduced in FECOPD group. Conclusions: The patients in FECOPD group had clinical, spirometric, and transfer test profiling suggestive of a severe COPD phenotype, the recognition will help in predicting future exacerbations and a better management.

    Objective: To determine the frequency of Streptococcus pneumoniae and Haemophilus influenzae in acute exacerbation of chronic obstructive pulmonary disease and their sensitivity to levofloxacin. Methods: The cross-sectional study was conducted at the Department of Medicine, AbbasiShaheed Hospital, Karachi, between July 2009 and January 2010. Patients already diagnosed with chronic obstructive pulmonary disease and admitted with symptoms of acute exacerbation were included in the study and their sputum samples were sent for microbiological evaluation. SPSS 16 was used for statistical analysis. Results: Of the total 105 patients in the study, 90 (85.17%) were males. Overall mean age at presentation was 62+-10.2 years. S. pneumoniae was isolated from sputum culture of 33 (31.4%) patients, while 13 (12.4%) patients showed growth of H. influenzae. Out of the 33 sputum specimens of S. pneumoniae, 32 (97.0%) were sensitive to levofloxacin, while 1 (3.0%) was resistant. All the 13 isolates of H. influenzae were sensitive to levofloxacin. Conclusion: S. pneumoniae and H. influenzae are still the most prevalent organisms isolated in acute exacerbation of chronic obstructive pulmonary disease in our population. Levofloxacin is still considered a highly sensitive antibiotic against these common micro-organisms in our population, but S. pneumoniae has started developing resistance against levofloxacin. Therefore, intermittent surveillance regarding development of resistance pattern of common micro-organisms against commonly prescribed antibiotics is required. (author)

    Nucleosomes and cell-free double-stranded DNA (dsDNA) have been suggested as promising biomarkers in cell death-related diseases, such as acute coronary syndrome (ACS). Currently, the impact of obstructive sleep apnea (OSA) in patients with ACS is unclear. Our aim was to evaluate the relationship between OSA, dsDNA, and nucleosomes and to assess their potential implication in the development of ACS. Up to 549 patients were included in the study and divided into four groups (145 ACS; 290 ACS + OSA; 62 OSA; 52 controls). All patients underwent a sleep study, and serum concentrations of dsDNA and nucleosomes were measured. Nucleosome and dsDNA levels were higher in patients with OSA than in controls (nucleosomes: 1.47 ± 0.88 arbitary units [AU] vs. 1.00 ± 0.33 AU; p Sleep Research Society 2017.

    2012-01-01

    Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

    AIM: To summarize our experience with the application of self-expanding metallic stent (SEMS) in the management of acute left-sided colorectal malignant obstruction.METHODS: A retrospective chart review of all patients undergoing placement of SEMS between April 2000 and January 2004 was performed.RESULTS: Insertion of SEMS was attempted in 26patients under fluoroscopic guidance with occasional endoscopic assistance. The sites of lesions were located in splenic flexure of two patients, left colon of seven patients, sigmoid colon of eight patients and rectum of nine patients. The intended uses of SEMS were for palliation in 7 patients and as a bridge to elective surgery in 19 patients. In the latter group, placement of SEMS allowed for preoperative systemic and bowel preparation and the following one-stage anastomosis. Successful stent placement was achieved in 22 (85%) of the 26patients. The clinical bowel obstruction resolved 24 hours after successful stent placement in 21 (95%) patients.Three SEMS-related minor complications occurred, two stents migrated and one caused anal pain.CONCLUSION: SEMS represents an effective and safe tool in the management of acute malignant colorectal obstruction. As a bridge to surgery, SEMS can provide time for systematic support and bowel preparation and obviate the need for fecal diversion or on-table lavage.As a palliative measure, SEMS can eliminate the need for emergent colostomy.

    Small bowel obstruction (SBO) is characterized by a high rate of recurrence. In the present study, we aimed to compare the outcomes of patients managed either by conservative treatment or surgical operation for an episode of SBO. The outcomes of all patients hospitalized at a single center for acute SBO between 2004 and 2007 were assessed. The occurrence of recurrent hospitalization, surgery, SBO symptoms at home, and mortality was determined. Among 221 patients admitted with SBO, 136 underwent a surgical procedure (surgical group) and 85 were managed conservatively (conservative group). Baseline characteristics were similar between treatment groups. The median follow-up time (interquartile range) was 4.7 (3.7-5.8) years. Nineteen patients (14.0 %) of the surgical group were hospitalized for recurrent SBO versus 25 (29.4 %) of the conservative group [hazard ratio (HR), 0.5; 95 % CI, 0.3-0.9]. The need for a surgical management of a new SBO episode was similar between the two groups, ten patients (7.4 %) in the surgical group and six patients (7.1 %) in the conservative group (HR, 1.1; 95 % CI, 0.4-3.1). Five-year mortality from the date of hospital discharge was not significantly different between the two groups (age- and sex-adjusted HR, 1.1; 95 % CI, 0.6-2.1). A follow-up evaluation was obtained for 130 patients. Among them, 24 patients (34.8 %) of the surgical group and 35 patients (57.4 %) of the conservative group had recurrent SBO symptoms (odds ratio, 0.4; 95 % CI, 0.2-0.8). The recurrence of SBO symptoms and new hospitalizations were significantly lower after surgical management of SBO compared with conservative treatment.

    A male tetraplegic patient attended accident and emergency with a blocked catheter; on removing the catheter, he passed bloody urine. After three unsuccessful attempts were made to insert a catheter by nursing staff, a junior doctor inserted a three-way Foley catheter with a 30-mL balloon but inflated the balloon with 10 mL of water to commence the bladder irrigation. The creatinine level was mostly 19 µmol/L (range: 0-135 µmol/L) but increased to 46 µmol/L on day 7. Computerized tomography urogram revealed that the bilateral hydronephrosis with hydroureter was extended down to urinary bladder, the bladder was distended, prostatic urethra was dilated and filled with urine, and although the balloon of Foley catheter was not seen in the bladder, the tip of the catheter was seen lying in the urethra. Following the re-catheterization, the creatinine level decreased to 21 µmol/L. A follow-up ultrasound scan revealed no evidence of hydronephrosis in both kidneys. Flexible cystoscopy revealed inflamed bladder mucosa, catheter reaction, and tiny stones. There was no bladder tumor. This case report concludes that the cause of bilateral hydronephrosis, hydroureter, and distended bladder was inadequate drainage of urinary bladder as the Foley balloon that was under-filled slipped into the urethra resulting in an obstruction to urine flow. Urethral catheterization in tetraplegic patients should be performed by senior, experienced staff in order to avoid trauma and incorrect positioning. Tetraplegic subjects with decreased muscle mass have low creatinine level. Increase in creatinine level (>1.5 times the basal level) indicates acute kidney injury, although peak creatinine level may still be within laboratory reference range. While scanning the urinary tract of spinal cord injury patients with indwelling urinary catheter, if Foley balloon is not seen within the bladder, urethra should be scanned to locate the Foley balloon.

    Full Text Available The efficacy of magnesium sulphate in chronic obstructive pulmonary disease (COPD was assessed by conducting a systematic review of published randomized clinical trials through extensive searches in MEDLINE and SCOPUS with no date limits, as well as manual review of journals. Outcome measures varied depending on route(s of administration of magnesium sulphate and medications co-administered. Risk of bias was evaluated and quality of evidence was graded. Four (4 randomized trials were included. All trials had a moderate risk of bias and were of average methodological quality. Magnesium sulphate given intravenously did not seem to have an immediate bronchodilatory effect; however it appears to potentiate the bronchodilatory effect of inhaled beta-2 agonists. Increase in peak expiratory flow rate (PEFR at 30 and 45 min was greater in those who received magnesium sulphate compared to placebo (P = 0.03, although the mean percentage change in PEFR was just 24%, without significant differences in dyspnoea scores, hospital admission rates, or emergency department readmission rates compared to placebo. Nebulized magnesium sulphate with salbutamol versus nebulized salbutamol with saline placebo showed no significant differences is forced expiratory volume in 1 s (FEV 1 measured at 90 min after adjustment for baseline FEV 1 (P = 0.34 or differences in the need for hospital admission. Combined inhalational and intravenous magnesium sulphate versus intravenous saline placebo and nebulized ipratropium bromide were comparable in terms of hospital admission, intubation and death, but the ipratropium bromide group showed better bronchodilator effect and improvement in arterial blood gas parameters. Overall, trial evidence for trial evidence for magnesium sulphate in acute exacerbation of COPD is poor, and further well-designed trials are needed.

    Full Text Available Objective: To explore the clinical efficacy of budesonide in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD. Methods: A total of 60 patients with moderate and severe AECOPD who were admitted in our hospital from January, 2015 to January, 2016 were included in the study and randomized into the experiment group and the control group. The patients in the two groups were given oxygen inhalation, anti-infection, phlegm dispersing, ipratropium bromide (0.5 mg/time, and aerosol liquid of salbutamol sulfate (2.5 mg/time, 3 times/d, 20 min/time, aerosol inhalation. The patients in the experiment group were given budesonide (2 mg/time, while the patients in the control group were given budesonide (1 mg/time, every 8 h for one aerosol inhalation. The patients in the two groups were continuously treated for 7 d. The changes of PaO2, PaCO2, FEV1, and FEV1/FVC before and after treatment were detected, and the efficacy was evaluated. Results: After treatment, PaO2 and PaCO2 in the two groups were significantly improved when compared with before treatment, and the improved degree in the observation group was significantly superior to that in the control group. After treatment, FEV1 and FEV1/FVC in the two groups were significantly improved when compared with before treatment, and the improved degree in the observation group was significantly superior to that in the control group. The total effective rate in the observation group (93.33% was significantly higher than that in the control group (76.67%. Conclusions: Aerosol inhalation of budesonide in the treatment of AECOPD in a large dose for a short term can significantly improve the blood gas and pulmonary function.

    Acute pancreatitis is a common diagnosis worldwide, with gallstone disease being the most prevalent cause (50%). The American College of Gastroenterology recommends urgent endoscopic retrograde cholangiopancreatography (ERCP) (within 24 h) for patients with biliary pancreatitis accompanied by cholangitis. Most international guidelines recommend that ERCP be performed within 72 h in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, but the optimal timing for endoscopy is controversial. We investigated the optimal timing for ERCP in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, and whether performing endoscopy within 24 h is superior to performing it after 24 h. We analyzed the clinical data of 505 patients with newly diagnosed acute pancreatitis, from January 1, 2005 to December 31, 2014. We divided the patients into two groups according to the timing of ERCP: pancreatitis and a bile duct obstruction without cholangitis. The mean age of the patients was 55 years (range: 26-90 years). Bile duct stones and biliary sludge were identified on endoscopy in 45 (61.6%) and 11 (15.0%) patients, respectively. The timing of ERCP within 72 h was not associated with ERCP-related complications (P = 0.113), and the total length of hospital stay was not different between urgent and early ERCP (5.9 vs. 5.7 days, P = 0.174). No significant differences were found in total length of hospitalization or procedural-related complications, in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, according to the timing of ERCP (< 24 h vs. 24-72 h).

    Full Text Available Goblet cell carcinoid (GCC is a rare variant of carcinoid tumor that exclusively involves the appendix. It usually occurs in 5 th -6 th decade with the most common clinical presentation being acute appendicitis. The natural history of this tumor is intermediate between carcinoids and adenocarcinomas. We here report a case of GCC diagnosed incidentally in a patient presenting with acute intestinal obstruction. Ultrasonographic examination supported the clinical diagnosis of acute intestinal obstruction, following which the patient underwent laparotomy and resection of ileum along with appendix was done. On gross pathological examination, a nodular growth was present on the tip and body of appendix that was yellow in color with a semi-solid to mucoid consistency on cut section. On microscopy, lakes of mucin with few acinar structures floating in them were seen. The submucosa as well as serosa were infiltrated by clusters of goblet cells and well-formed acini, with little atypia. Glands and nests were positive for per-iodic acid Schiff and immunohistochemistry showed focal chromogranin positivity in glandular structures, thereby confirming the diagnosis of GCC. Although the prognosis of GCC is better than adenocarcinomas, it is one of the carcinoids having a poorer outcome when compared with other variants of carcinoid tumor. Therefore, it is important to rule out other differential diagnoses of goblet cell carcinoid, the most important being mucinous adenocarcinomas.

    A 70-year-old man with recurrent undiagnosed episodes of bronchial cast expectoration and pulmonary infiltrates on chest radiography for 15 years is described. The diagnosis of chyloptysis was established by chemical analysis of the bronchial aspiration. We emphasize the radiological findings of this rare observation. The CT-associated lymphangiography showed mediastinal lymphangiectasis with retrograde opacification of mediastinal and hilar lymph nodes as well as submucosal lymphatic vessels protruding into the lumen of the tracheo-bronchial tree without evidence of thoracic duct obstruction as well as a ''crazy-paving appearance.'' Congenital incompetence of the valves of the lymphatic vessels originating from the thoracic duct is held to be the cause. Chyloptysis and pulmonary lymphatic disorder should be sought in cases of bronchial cast expectoration. (orig.)

    To investigate the clinical advantages of the stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction (ACO). From April 2008 to April 2012, surgery-related parameters, complications, overall survival (OS), and disease-free survival (DFS) of 74 consecutive patients with left-sided CRC presented with ACO who underwent self-expandable metallic stent (SEMS) placement followed by one-stage open (n = 58) or laparoscopic resection (n = 16) were evaluated retrospectively. The stent-laparoscopy group was also compared with a control group of 96 CRC patients who underwent regular laparoscopy without ACO between January 2010 and December 2011 to explore whether SEMS placement influenced the laparoscopic procedure or reduced long-term survival by influencing CRC oncological characteristics. The characteristics of patients among these groups were comparable. The rate of conversion to open surgery was 12.5% in the stent-laparoscopy group. Bowel function recovery and postoperative hospital stay were significantly shorter (3.3 ± 0.9 d vs 4.2 ± 1.5 d and 6.7 ± 1.1 d vs 9.5 ± 6.7 d, P = 0.016 and P = 0.005), and surgical time was significantly longer (152.1 ± 44.4 min vs 127.4 ± 38.4 min, P = 0.045) in the stent-laparoscopy group than in the stent-open group. Surgery-related complications and the rate of admission to the intensive care unit were lower in the stent-laparoscopy group. There were no significant differences in the interval between stenting and surgery, intraoperative blood loss, OS, and DFS between the two stent groups. Compared with those in the stent-laparoscopy group, all surgery-related parameters, complications, OS, and DFS in the control group were comparable. The stent-laparoscopy approach is a feasible, rapid, and minimally invasive option for patients with ACO caused by left-sided CRC and can achieve a favorable long-term prognosis.

    The self-expandable metallic stent (SEMS) is an excellent non-invasive tool for emergent bowel obstruction. This study was designed to evaluate the clinical usefulness of the SEMS for avoiding perioperative complications. We analyzed a total of 47 consecutive patients who had a bowel obstruction due to colorectal cancer at initial diagnosis between 2012 and 2017 from hospital records. Perioperative complications occurred in 30% (14/47) of patients. Univariate and multivariate logistic regression analyses identified an age of more than 75 years [p=0.037, OR=6.84 (95% CI=1.11-41.6)] and the absence of an SEMS treatment [p=0.028, OR=18.5 (95% CI=1.36-250.0)] as independent risk factors for perioperative complications. Pneumonia (12.7% (6/47)) was the most common complication. There were no pneumonia patients (0% (0/15)) who were treated with the SEMS. In contrast to patients with the non-SEMS treatment, 18.7% (6/32) of all patients and 35.7% (5/14) of elderly patients had pneumonia. The SEMS is a safe and effective treatment for avoiding perioperative complications, particularly pneumonia, and may be a crucial strategy in elderly patients with acute obstruction due to colorectal cancer.

    The purpose of this study was to evaluate the feasibility of CT colonography for preoperative examination of the proximal colon using a transanal drainage tube in patients with acute colon obstruction caused by colorectal cancer. Ten patients who received initial treatment for acute malignant colon obstruction at our hospital between June 2004 and December 2008 were studied. In these patients, elective surgery was possible after transanal drainage tube insertion, and the colon on the oral side from the cancer lesion was examined using a drainage tube. Air was injected through the tube into the oral side of the colon, and CT colonography was assessed for the presence or absence of lesions on the oral side. The images of the oral side of the colon were good enough to allow adequate interpretation in 9 of the 10 patients. In the first patient, the visualization of the area near the lesion was somewhat fair, although the right side colon was well visualized. There were no complications associated with this examination. The present preoperative examination using a transanal drainage tube was useful for determining the extent of intestinal resection when patients were not candidates for colonoscopy or barium enema examination.

    We aimed to study survival and causes of death in patients with ST-elevation acute coronary syndrome (STE-ACS) with and without obstructive coronary artery disease (CAD). We included 4793 consecutive patients with STE-ACS triaged for acute coronary angiography at a large cardiac invasive centre (2009-2014). Of these, 88% had obstructive CAD (stenosis ≥50%), 6% had non-obstructive CAD (stenosis 1-49%), and 5% had normal coronary arteries. Patients without obstructive CAD were younger and more often female with fewer cardiovascular risk factors. Median follow-up time was 2.6 years. Compared with patients with obstructive CAD, the short-term hazard of death (≤30 days) was lower in both patients with non-obstructive CAD [hazard ratio (HR) 0.49, 95% confidence interval (CI) 0.27-0.89, P = 0.018] and normal coronary arteries (HR 0.31, 95% CI 0.11-0.83, P = 0.021). In contrast, the long-term hazard of death (>30 days) was similar in patients with non-obstructive CAD (HR 1.15, 95% CI 0.77-1.72, P = 0.487) and higher in patients with normal coronary arteries (HR 2.44, 95% CI 1.58-3.76, P Causes of death were cardiovascular in 70% of patients with obstructive CAD, 38% with non-obstructive CAD, and 32% with normal coronary arteries. Finally, patients without obstructive CAD had lower survival compared with an age and sex matched general population. STE-ACS patients without obstructive CAD had a long-term risk of death similar to or higher than patients with obstructive CAD. Causes of death were less often cardiovascular. This suggests that STE-ACS patients without obstructive CAD warrant medical attention and close follow-up. Published on behalf of the European Society of Cardiology.

    A three-dimensional (3-D) tissue-like assembly (TLA) of human bronchial-tracheal mesenchymal (HBTC) cells with an overlay of human bronchial epithelial (BEAS-2B) cells was constructed using a NASA Bioreactor to survey the infectivity of SARS-CoV. This TLA was inoculated with a low passage number Urbani strain of SARS-CoV. At selected intervals over a 10-day period, media and cell aliquots of the 3-D TLA were harvested for viral titer assay and for light and electron microscopy examination. All viral titer assays were negative in both BEAS-2B two-dimensional monolayer and TLA. Light microscopy immunohistochemistry demonstrated antigen-antibody reactivity with anti-SARS-CoV polyclonal antibody to spike and nuclear proteins on cell membranes and cytoplasm. Coronavirus Group 2 cross-reactivity was demonstrated by positive reaction to anti-FIPV 1 and anti-FIPV 1 and 2 antibodies. TLA examination by transmission electron microscopy indicated increasing cytoplasmic vacuolation with numerous electron-dense bodies measuring 45 to 270 nm from days 4 through 10. There was no evidence of membrane blebbing, membrane duplication, or fragmentation of organelles in the TLAs. However, progressive disruption of endoplasmic reticulum was observed throughout the cells. Antibody response to SARS-CoV specific spike and nucleocapsid glycoproteins, cross-reactivity with FIPV antibodies, and the cytoplasmic pathology suggests this HBTE TLA model is permissive to SARS-CoV infection.

  20. [Diagnosis and differential diagnosis of bronchial asthma].

    Science.gov (United States)

    Gillissen, A; Bauer, T; Richter, F; Leonhardt, P

    2001-11-01

    Asthma and COPD (chronic obstructive pulmonary disease) are the most important obstructive pulmonary diseases. Patient's history and physical evaluation give major hints of the underlying disease. Further diagnostic measures comprise lung function analysis including spirometry, plethysmography and--in severe cases--blood gas analysis. Bronchial hyperreactivity may be quantified with an unspecific inhalative provocation test. In many cases allergic diseases are accompanied by asthma. Thus, allergy tests--particularly skin prick tests--have to be carried out. To further define an underlying allergy, in some cases even specific inhalative provocation tests have to be performed. X-ray of the thorax and other imaging techniques, detailed blood analysis, further diagnosis of the upper respiratory tract and the cardiac system may have to be carried out a) to quantify the effects of a severe form of asthma or COPD on other organs, and b) for differential diagnostic examinations.

  1. Correlation between arterial and venous blood gas analysis parameters in patients with acute exacerbation of chronic obstructive pulmonary disease

    2012-01-01

    Full Text Available Introduction. Arterial blood gas (ABG analyses have an important role in the assessment and monitoring of the metabolic and oxygen status of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD. Arterial puncture could have a lot of adverse effects, while sampling of venous blood is simpler and is not so invasive. Objective. The aim of this study was to evaluate whether venous blood gas (VBG values of pH, partial pressure of carbon dioxide (PCO2, partial oxygen pressure (PO2, bicarbonate (HCO3, and venous and arterial blood oxygen saturation (SO2 can reliably predict ABG levels in patients with acute exacerbation of COPD. Methods. Forty-seven patients with a prior diagnosis of COPD were included in this prospective study. The patients with acute exacerbation of this disease were examined at the General Hospital EMS Department in Prijepolje. ABG samples were taken immediately after venous sampling, and both were analyzed. Results. The Pearson correlation coefficients between arterial and venous parameters were 0.828, 0.877, 0.599, 0.896 and 0.312 for pH, PCO2, PO2, HCO3 and SO2, respectively. The statistically significant correlation between arterial and venous pH, PCO2 and HCO3, values was found in patients with acute exacerbation of COPD (p<0.001. Conclusion. When we cannot provide arterial blood for analysis, venous values of the pH, Pv,CO2 and HCO3 parameters can be an alternative to their arterial equivalents in the interpretation of the metabolic status in patients with acute exacerbation of COPD, while the values of venous Pv,O2 and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

    To evaluate the feasibility of CT fluoroscopy (CTF)-guided percutaneous transhepatic biliary drainage (PTBD) in emergency patients with acute obstructive cholangitis. The study included 28 patients admitted to the emergency center due to obstructive jaundice and found to require urgent biliary drainage, as well as judged to have a suitable peripheral bile duct for a CTF-guided puncture (at least 4 mm in width). Prior to the CTF-guided puncture, a CT scan was performed to evaluate bile duct dilatation and the underlying causes of biliary obstruction. If the patient was judged to be a suitable candidate, a CTF-guided PTBD was performed in the same CT unit without additional fluoroscopic guidance. Technical feasibility of the procedure was investigated with the evaluation of overall success rate and causes of failure. A hepatic puncture was attempted at the left lobe in 23 patients and right lobe in five patients. The procedure was successful in 24 of 28 patients (86%) Successful biliary puncture was achieved on the first attempt in 16 patients, the second attempt in five patients, and the third attempt in three patients. The causes of failure included guide wire twisting in one patient, biliary puncture failure in two patients, and poor visualization of the guide wire in one patient. There were no significant procedure-related complication. The CTF-guided PTBD is technically feasible and highly successful in patients judged to have a suitable indication. Moreover, although the procedure is unfamiliar and inconvenient to interventionalists, it has economical advantages in that it saves time and manpower. We believe this method can be used in the emergency patients requiring urgent biliary drainage as an alternative for the fluoroscopy-guided PTBD.

    To determine whether an early rehabilitation program was safe and feasible for patients during an acute exacerbation of chronic obstructive pulmonary disease (COPD). In this phase 1 randomized controlled trial, patients with an acute exacerbation of COPD admitted to the hospital were randomly allocated to a low-intensity exercise group, a moderate- to high-intensity exercise group, or a control group, who received routine physical therapy. In addition to routine physical therapy, patients in the exercise group had to participate in an exercise program. The program consisted of twice-daily aerobic and resistance exercise sessions. Primary outcomes were the number and classification of adverse events and program adherence. In 174 exercise sessions, there was 1 serious adverse event of arrhythmia in the low-intensity exercise group that resolved within 1 hour. There were 12 other minor adverse events involving 5 patients with no significant differences between groups. Patients completed an average of 80% of their scheduled sessions with no significant between-group differences. The exercise groups improved significantly in walking distance; however, no significant between-group differences were observed. There was preliminary evidence that it was safe and feasible to implement an exercise program for patients during an acute exacerbation of COPD. Additional studies with larger sample sizes are required to accurately evaluate program effectiveness.

    Bezoars are concretions or hard masses of foreign matter that are found in the gastrointestinal tract. Recent reports have demonstrated the efficacy of Coca-Cola administration for the dissolution of phytobezors. Here we report on a 73-year-old man with a very large gastric persimmon diospyrobezoar, and this caused small intestinal obstruction after partial dissolution with oral and injected Coca-Cola.

    1986-04-01

    Full Text Available This report describes two patients with chronic Chagas' Heart Disease who developed clinical and laboratorial signs of myocardial infarction. Both patients presented sudden oppressive chest pain, without precipitating factor. In the first case, the highest MB-CK value was 65 IU, 22 hours after the beginning of the pain. On the second case, it was 77 IU at 18 hours after the beginning of the pain. In both cases ECG changes suggesting non-transmural infarction were present. The 99mTc PYP myocardial scintigram of the first case was positive. Coronary angiograms performed on the 18th and 9th day, respectively, after the acute infarction did not display obstructive lesions. Possible mechanisms causing myocardial infarction with normal coronary arteries in Chagas' Disease may include: embolic event's, particularly when there is associated congestive heart failure; coronary thrombosis and coronary spasms.

    Full Text Available The article highlights the results of the act test based bronchial asthma supervision evaluation among teenagers and defines the interrelation of the objective and subjective asthma supervision parameters. The researchers examined 214 male teenagers aged from 16 to 18, suffering from the bronchial asthma, who were sent to the allergy department to verify the diagnosis. Bronchial asthma supervision evaluation was assisted by the act test. The research has showed that over a half (56% of teenagers, suffering from mild bronchial asthma, mention its un control course, do not receive any adequate pharmacotherapy and are consequently a risk group in terms of the bronchial asthma exacerbation. Act test results correlate with the functional indices (fev1, as well as with the degree of the bronchial hyperresponsiveness, which is one of the markers of an allergic inflammation in the lower respiratory passages.Key words: bronchial asthma supervision, act test, teenagers.

    Full Text Available Objectives: Readmission rate is increasingly being viewed as a key indicator of health system performance. Medication regimen complexity index scores may be predictive of readmissions; however, few studies have examined this potential association. The primary objective of this study was to determine whether medication regimen complexity index is associated with all-cause 30-day readmission after admission for heart failure, acute myocardial infarction, pneumonia, or chronic obstructive pulmonary disease. Methods: This study was an institutional review board–approved, multi-center, case–control study. Patients admitted with a primary diagnosis of heart failure, acute myocardial infarction, pneumonia, or chronic obstructive pulmonary disease were randomly selected for inclusion. Patients were excluded if they discharged against medical advice or expired during their index visit. Block randomization was utilized for equal representation of index diagnosis and site. Discharge medication regimen complexity index scores were compared between subjects with readmission versus those without. Medication regimen complexity index score was then used as a predictor in logistic regression modeling for readmission. Results: Seven hundred and fifty-six patients were randomly selected for inclusion, and 101 (13.4% readmitted within 30 days. The readmission group had higher medication regimen complexity index scores than the no-readmission group (p < 0.01. However, after controlling for demographics, disease state, length of stay, site, and medication count, medication regimen complexity index was no longer a significant predictor of readmission (odds ratio 0.99, 95% confidence interval 0.97–1.01 or revisit (odds ratio 0.99, 95% confidence interval 0.98–1.02. Conclusion: There is little evidence to support the use of medication regimen complexity index in readmission prediction when other measures are available. Medication regimen complexity index

    2016-01-01

    Full Text Available Acute exacerbations are significant and frequent events in the natural history of chronic obstructive pulmonary disease. Majority of these exacerbations are of infectious aetiology, bacteria being responsible for 30-50% of these cases. With not many studies of similar type being conducted in the Indian context, this study was undertaken with the purpose of determining the bacteriology of acute exacerbations of chronic obstructive pulmonary disease in hospitalized patients with advanced disease and their antibiotic susceptibility pattern to formulate a cost effective algorithm for antibiotic usage while at the same time reducing the chances of emergence of drug resistance. Sputum sample from a total of 338 patients were send for Gram’s stain and culture sensitivity testing using an array of the commonly used antibiotics. Pathogenic bacteria were isolated from 203 (60.1% samples. Gram negative bacteria were isolated from 79.8 percent (162/203 cases while the rest were Gram positive. Klebsiella species were the commonest (49.2%; 100/203 Gram negative isolates from the sputum samples. Among the gram negative organisms, Carbapenem had the highest sensitivity (90.2% followed by Amikacin, Ciprofloxacin and Piperacillin-Tazobactam. Linezolid was found to be 100 percent sensitive amongst the Gram positive organisms while both Amoxicillin Clavulanate and Azithromycin showed a rather low sensitivity profile overall. 5.0 percent of the Klebsiella infections were multi drug resistant. It was thereby concluded that either Amikacin, Ciprofloxacin or Piperacillin-Tazobactam for be considered for Gram negative organisms and Linezolid be considered for Gram positive organisms as first line antibiotics in empirical therapy while Carbapenems may be kept as reserve drugs should the first line drugs fail.

    A study on obstructive changes in airways and mucociliary clearance in children and youth with bronchial asthma was performed. Radioaerosol inhalation lung scintigraphies using 99T c-human serum albumin (HSA) were applied to 50 children and youth with bronchial asthma. The deposition patterns of the radioaerosol and aerosol clearance curves were evaluated. Abnormal deposition patterns, which consisted of non-homogeneous distribution and/or hot spot formation, were likely to be seen in patients with asthmatic attacks at the time of measurements. However, a few asymptomatic patients also revealed abnormal deposition patterns. The deposition patterns were related to FEV 1.0 %, MMF, V 50 and V 25 , but especially to FEV 1.0 %. As an index of mucociliary clearance, β, the rate constant of the 99m Tc-HSA aerosol clearance curve, was introduced. β was significantly lower in patients with abnormal aerosol deposition patterns than in normal persons. β was also significantly lower in patients undergoing asthmatic attack at the time of the measurements than in asymptomatic patients. β correlated negatively with FEV 1.0 %, MMF, V 50 and V 25 , but especially with FEV 1.0 %. Although patients with long term affection or moderate-to-severe asthma tended to reveal abnormal deposition patterns and had low β values, these differences were not statistically significant. Radioaerosol inhalation lung scintigraphy with 99m Tc-HSA is useful for evaluating not only obstructive changes in the airways but also for evaluating mucociliary clearance in children with bronchial asthma.

    PurposeDue to high thrombus load, acute stroke patients with tandem obstructions of the extra- and intracranial carotid arteries or the middle cerebral artery show a very limited response to systemic thrombolysis. Interventional treatment with mechanical thrombectomy—often in combination with acute stenting of underlying atherosclerotic stenosis or dissection—is increasingly used. It has been shown that such complex interventions are technically feasible. The lack of optimal management strategies and clinical data encouraged us to review our acute stroke interventions in patient with anterior circulation tandem lesions to determine lesion patterns, interventional approaches, and angiographic or clinical outcomes.Patients and MethodsWe retrospectively analyzed a series of 39 consecutive patients with intracranial vessel occlusion of the anterior circulation simultaneously presenting with high-grade cervical internal carotid artery (ICA) stenosis or occlusion.ResultsEmergency ICA stent implantation was technically feasible in all patients, and intracranial recanalization with TICI ≥ 2b was reached in a large number of patients (64 %). Good clinical outcomes (mRS ≤ 2 at 3 months) were achieved in one third of the patients (36 %). Symptomatic hemorrhages occurred in four patients (10 %). Mortality was 10 %.ConclusionEndovascular recanalization of acute cervical carotid artery occlusion was technically feasible in all patients, and resulted in high extra- and intracranial revascularization rates. A trend for favorable clinical outcome was seen in a higher TICI score, younger age, good collateral status, and combined IV rTPA and endovascular therapy

    Obstructive sleep apnea (OSA) occurs commonly in the U.S. population and is seen in both obese as well as non-obese individuals. OSA is a disease characterized by periodic upper airway collapse during sleep, which then results in either apnea, hypopnea, or both. The disorder leads to a variety of medical complications. Neuropsychiatric complications include daytime somnolence, cognitive dysfunction, and depression. Increased incidence of motor vehicle accidents has been documented in these patients and probably reflects disordered reflex mechanisms or excessive somnolence. More importantly, vascular disorders such as hypertension, stroke, congestive cardiac failure, arrhythmias, and atherosclerosis occur frequently in these patients. The lungs may be affected by pulmonary hypertension and worsening of asthma. Recent data from several laboratories demonstrate that obstructive sleep apnea is characterized by an inflammatory response. Cytokines are elaborated during the hypoxemic episodes leading to inflammatory responses as marked clinically by elevated C-reactive protein (CRP). As elevated CRP levels are considered markers of the acute phase response and characterize progression of vascular injury in coronary artery disease, it is likely that obstructive sleep apnea could lead to worsening of vasculopathy. Moreover, as inflammatory mechanisms regulate bronchial asthma, it is also likely that cytokines and superoxide radicals generated during hypoxemic episodes could exacerbate reactive airway disease. Patients with Cough, Obstructive sleep apnea, Rhinosinusitis, and Esophageal reflux clustered together can be categorized by the acronym, "CORE", syndrome. The purpose of this manuscript is to review the inflammatory responses that occur in patients with obstructive sleep apnea and relate them to the occurrence of cardiopulmonary disease.

    Bronchial foreign bodies by children are dangerous and require immediate therapeutic measures. Findings and significance of chest film in the diagnosis of bronchial foreign bodies in 24 children were analysed. All patients were symptomatic. 18 patients had an abnormal and 6 normal auscultation finding. In three cases the physician did not suspect aspiration, and the diagnosis was delayed, which caused the death of one child. Roentgenpositive foreign bodies were found in 8 and -negative in 16 cases. Secondary changes (obstructive emphysema, atelectasis, pneumonia) were seen in 16 cases. In emergency cases the chest films were analysed by physician and later by a radiologist, who found 88% of them to be abnormal. Fluoroscopy of expiratory chest film helps to detect the unilateral emphysema more distinctly. The diagnosis must always be confirmed with bronchoscopy and extraction thereby is the adequate treatment of bronchial bodies. (orig.) [de

    The objective of the present study was to estimate the clinical effectiveness of fenspiride used to correct the obstruction of the Eustachian tube in 80 patients presenting with acute tubootitis and exudative otitis media. The algorithm of the examination included the evaluation of the severity of subjective clinical symptoms based on the relevant analog-visual scale, results of tonal audiometry, and tympanometry. The control group was comprised of 34 patients treated with antibacterial preparations, topical decongestants, and transtubal administration of glucocorticoids. The study group included 46 patients who received fenspiride at a dose of 80 mg thrice daily in addition to the above pharmacotherapy. The severity of clinical symptoms in the patients treated with fenspiride decreased faster than in the control subjects. The frequency analysis of dynamics of the air-bone gaps on the audiometric curves revealed the significantly more intensive recovery of the hearing function in the patients treated by basal pharmacotherapy in the combination with fenspiride. Type A tympanograms predominated on day 7 after the onset of the conservative treatment with the use of fenspiride whereas type C tympanograms continued to predominate in the patients of the control group. It is concluded that the introduction of fenspiride into combined therapy of acute tubootitis and exudative otitis media promotes the normalization of the ventilation and drainage functions and relieves the severity of subjective clinical symptoms.

    We studied the effect of a non-steroidal anti-inflammatory drug fenspiride on contractive activity of bronchial smooth muscles on the model of chronic obstructive pulmonary disease of rats induced by 60-day exposure to nitrogen dioxide. The administration of fenspiride during the acute stage of the disease (day 15) abolished the constricting effect of the pollutant on the bronchial smooth muscles. Dilatation effect of fenspiride in a low dose (0.15 mg/kg) was mediated by its interaction with nerve endings of bronchial capsaicin-sensitive nerve C-fibers. The interaction of drug with receptors of C-fibers prevented neurogenic inflammation, which was confirmed by the absence of structural changes in the lungs typical of this pathology. The broncholytic effect of fenspiride in a high dose (15 mg/kg) was mediated by not only afferent pathways, but also its direct relaxing action on smooth muscle cells. The observed anti-inflammatory and bronchodilatation effect of fenspiride in very low doses can be used for prevention of chronic obstructive pulmonary disease in risk-group patients contacting with aggressive environmental factors.

    To assess bronchial morphology and abnormality, 14 children with congenital heart diseases including 2 postoperative patients (age, 2 m.-4 yr) were studied by digital video subtraction fluorography (DVSF) using digital subtraction and image processing system (Philips, DVI-2). This newly developed technique clearly defined bronchial anatomy in all 14 patients. Bronchial situs could be determined in all 8 patients with complex heart anomalies. Out of 8 patients with respiratory distress in this study, obvious bronchial stenosis or obstruction was found by DVSF in 5 patients. Thus, DVSF image defined anatomies of main and lobar bronchi more clearly than previous noninvasive methods. Moreover, DVSF is noninvasive and easily performed even for small infants and critically ill patients. In conclusion, DVSF may be a useful technique to assess bronchial morphology and abnormality in patients with congenital heart diseases. (author)

    Full Text Available In this review we discuss the potential of a new procedure, termed Bronchial Thermoplasty to prevent serious consequences resulting from excessive airway narrowing. The most important factor in minimizing an asthmatic attack is limiting the degree of smooth muscle shortening. The premise that airway smooth muscle can be either inactivated or obliterated without any long-term alteration of other lung tissues, and that airway function will remain normal, albeit with reduced bronchoconstriction, has now been demonstrated in dogs, a subset of normal subjects, and mild asthmatics. Bronchial Thermoplasty may thus develop into a useful clinical procedure to effectively impair the ability for airway smooth muscle to reach the levels of pathologic narrowing that characterizes an asthma attack. It may also enable more successful treatment of asthma patients who are unresponsive to more conventional therapies. Whether this will remain stable for the lifetime of the patient still remains to be determined, but at the present time, there are no indications that the smooth muscle contractility will return. This successful preliminary experience showing that Bronchial Thermoplasty could be safely performed in patients with asthma has led to an ongoing clinical trial at a number of sites in Europe and North America designed to examine the effectiveness of this procedure in subjects with moderately severe asthma.

    It is of value to update radon daughter bronchial dosimetry as new information becomes available. Measurements have now been performed using hollow casts of the human bronchial tree with a larynx to determine convective or turbulent deposition in the upper airways. These measurements allow a more realistic calculation of bronchial deposition by diffusion. Particle diameters of 0.15 and 0.2 μm were used which correspond to the activity median diameters for radon daughters in both environmental and mining atmospheres. The total model incorporates Yeh/Schum bronchial morphometry, deposition of unattached and attached radon daughters, build up and decay of the daughters and mucociliary clearance. The alpha dose to target cells in the bronchial epithelium is calculated for the updated model and compared with previous calculations of bronchial dose

    Luis Cláudio Lemos Correia

    Full Text Available Abstract Background: Currently, there is no validated multivariate model to predict probability of obstructive coronary disease in patients with acute chest pain. Objective: To develop and validate a multivariate model to predict coronary artery disease (CAD based on variables assessed at admission to the coronary care unit (CCU due to acute chest pain. Methods: A total of 470 patients were studied, 370 utilized as the derivation sample and the subsequent 100 patients as the validation sample. As the reference standard, angiography was required to rule in CAD (stenosis ≥ 70%, while either angiography or a negative noninvasive test could be used to rule it out. As predictors, 13 baseline variables related to medical history, 14 characteristics of chest discomfort, and eight variables from physical examination or laboratory tests were tested. Results: The prevalence of CAD was 48%. By logistic regression, six variables remained independent predictors of CAD: age, male gender, relief with nitrate, signs of heart failure, positive electrocardiogram, and troponin. The area under the curve (AUC of this final model was 0.80 (95% confidence interval [95%CI] = 0.75 - 0.84 in the derivation sample and 0.86 (95%CI = 0.79 - 0.93 in the validation sample. Hosmer-Lemeshow's test indicated good calibration in both samples (p = 0.98 and p = 0.23, respectively. Compared with a basic model containing electrocardiogram and troponin, the full model provided an AUC increment of 0.07 in both derivation (p = 0.0002 and validation (p = 0.039 samples. Integrated discrimination improvement was 0.09 in both derivation (p < 0.001 and validation (p < 0.0015 samples. Conclusion: A multivariate model was derived and validated as an accurate tool for estimating the pretest probability of CAD in patients with acute chest pain.

    This article offers a risk assessment of bronchial asthma development in children with atopic dermatitis by applying fuzzy-set theory to accumulated statistical data. It is shown that with a view to executing the said task one should exercise a complex approach involving factors such as "IgE level", "existence of obstructions" and "burdened bronchial asthma heredity of immediate relatives". The obtained results will assist in making adequate and well-informed medical decisions as well as facilitate the decrease of the risk of developing bronchial asthma in children with atopic dermatitis.

    Obstructive sleep apnea syndrome (OSA) is associated with systemic and upper airway inflammation. Pharyngeal inflammation has a potential role in upper airway collapse, whereas systemic inflammation relates to cardiovascular morbidity. However, the presence of an inflammatory involvement of lower airway has been poorly investigated. The aim of the study was to demonstrate an inflammatory process at the bronchial level in patients with OSA and to analyze effects of continuous positive airway pressure (CPAP) application and humidification on bronchial mucosa. The study was conducted by using sequential induced sputum for cell analysis and IL-8 production, nitric oxide exhalation measurement, and methacholine challenge before and after CPAP. Bronchial neutrophilia and a high IL-8 concentration were observed in untreated OSA compared with controls (75% +/- 20% vs 43% +/- 12%, P Obstructive sleep apnea syndrome is associated with bronchial inflammation. Our data demonstrate CPAP effect on the development of AHR, possibly facilitated by the pre-existing inflammation. Both issues should be evaluated during long-term CPAP use. Results showing a spontaneous bronchial inflammation in OSA and the development of a CPAP-related AHR require a long-term follow-up to evaluate consequences on chronic bronchial obstruction.

    Pandemic H1N1 influenza A (H1N1pdm) elicits stronger pulmonary inflammation than previously circulating seasonal H1N1 influenza A (sH1N1), yet mechanisms of inflammatory activation in respiratory epithelial cells during H1N1pdm infection are unclear. We investigated host responses to H1N1pdm/sH1N1 infection and virus entry mechanisms in primary human bronchial epithelial cells in vitro. H1N1pdm infection rapidly initiated a robust inflammatory gene signature (3 h post-infection) not elicited by sH1N1 infection. Protein secretion inhibition had no effect on gene induction. Infection with membrane fusion deficient H1N1pdm failed to induce robust inflammatory gene expression which was rescued with restoration of fusion ability, suggesting H1N1pdm directly triggered the inflammatory signature downstream of membrane fusion. Investigation of intra-virion components revealed H1N1pdm viral RNA (vRNA) triggered a stronger inflammatory phenotype than sH1N1 vRNA. Thus, our study is first to report H1N1pdm induces greater inflammatory gene expression than sH1N1 in vitro due to direct virus–epithelial cell interaction. - Highlights: • We investigated H1N1pdm/sH1N1 infection in primary epithelial cells. • H1N1pdm directly initiated a robust inflammatory gene signature, sH1N1 did not. • H1N1pdm viral RNA triggered a stronger response than sH1N1. • H1N1pdm induces greater response due to direct virus–cell interaction. • These results have potential to impact vaccine and therapeutic development.

    Chronic obstructive pulmonary disease (COPD) is associated with significant morbidity and mortality, and frequent exacerbations are associated with an increased risk of death, deterioration in lung function and reduced quality of life. Current Australian guidelines developed by the Lung Foundation of Australia (the COPD-X Plan) recommends the use of a short course of corticosteroids and oral antibiotics (amoxycillin or doxycycline) as part of the treatment of an AECOPD; however, it was noted that clinical practice at the study hospital had deviated from these guidelines. To evaluate the antibiotic prescribing practices in acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients, and to compare the differences in clinical outcomes (primarily mean length of stay and the rate of unplanned readmissions) between patients who received broad- vs. narrow-spectrum antibiotics in a large regional hospital. Retrospective audit of medical records for patients admitted with uncomplicated AECOPD during January-September, 2014 in a 224 acute bed regional hospital in Victoria, Australia. Fifty-nine per cent of patients received broad-spectrum antibiotics (ceftriaxone), whereas only 10% of prescriptions were concordant with current Australian guideline recommendations. Patients receiving a broad-spectrum regimen were more likely to be older (74·9 vs. 69·9 years; P = 0·009), have a higher COPD severity score (i.e. BAP-65 score, 1·55 vs. 1·06; P = 0·002) and a higher CRP (59·2 vs. 25·5 mg/L; P = 0·003) on admission. The mean LOS was not significantly different between those who received ceftriaxone and those who did not (5·09 vs. 4·55 days; P = 0·47). There was no significant difference between the groups in rates of readmissions. The antibiotic prescribing patterns for AECOPD in rural and regional Australian hospitals have not previously been examined in the current literature.

    Objective was to evaluate the efficacy of bronchial arteriography and bronchial artery embolization (BAE) in the management of massive hemoptysis in a developing Asian country. A retrospective review was carried out from March 2000 to March 2005 to evaluate the demographics, clinical presentation, radiographic studies, bronchoscopy results, and complications of bronchial arteriography and BAE at a tertiary care hospital in Pakistan. Fourteen patients (9males, 5 females) with a mean age of 49 years underwent bronchial arteriography and BAE for massive hemoptysis. Hemoptysis was caused by bronchiectasis (10 patients), active pulmonary tuberculosis (3 patients), and lung malignancy (one patient). A CT scan of the chest was carried out in 11 patients, which revealed bronchiectasis (8 patients), cavity with infiltrates (3 patients), and mass lesion (one patient). Bronchoscopy was performed in all patients. Bleeding lobe or segment was identified in 12 patients. Bronchial arteriography revealed hypervascularity (13 patients), bronchial artery hypertrophy (5 patients), hypervascularity with shunting (one patient), dense soft tissue staining (7 patients), extravasation of contrast (one patient) pseudoaneurysm (one patient). Bronchial artery embolization was carried out in all patients. Rebleeding occurred within 24 hours in 2 patients who underwent surgery and within one week another 2 patients who were managed with repeat BAE. The complication of embolization occurred in one patient (transverse myelitis). Thirteen patients improved and were discharged home. One patient with terminal lung carcinoma died due to cardiogenic shock secondary to acute myocardial infarction. Bronchial artery embolization is an effective method for management of massive hemoptysis in developing countries and has a low complication rate. (author)

    Objective: To study the prevalence of respiratory viral infection in chronic obstructive pulmonary disease(COPD) exacerbations and to find the factors associated with susceptibility to viral infections. Methods: Eighty patients with exacerbations of COPD and 50 stable COPD patients were recruited. Nasopharyngeal swabs were tested for a range of 18 different respiratory viruses using PCR. Results: Among the COPD exacerbations, viral infection was detected in 18 episodes (22.5%) . The most common virus was rhinovirus (33.3%), followed by coronavirus(27.8%), parainfluenza(22.2%), metapneumovirus(11.1%) and influenza virus B(5.6%). The prevalence of viral infection was 8% in the stable COPD patients. In multivariate regression analysis fever was found to be significantly associated with viral infections in COPD exacerbations (Odds ratio 4.99, 95% CI 1.51-16.48, P =0.008). Conclusion: Viral respiratory pathogens were more often detected in respiratory specimens from hospitalized patients with AECOPD than those with stable COPD. Rhinovirus was the most common infecting agent identified. The symptom of fever was associated with viral detection.

    The pathological changes in chronic bronchitis (CB) produce airflow obstruction, reduce the effectiveness of the mucocilliary drainage system and lead to bacterial colonisation of bronchial secretion. The presence of bacteria induces an inflammatory response mediated by leukocytes. There is a direct relationship between the degree of impairment of the mucocilliary drainage system, the density of bacteria in mucus and the number of leukocytes in the sputum. Purulent sputum is a good marker of a high bacterial load. Eventually, if the number of leukocytes is high, their normal activity could decrease the effectiveness of the drainage system, increase the bronchial obstruction and probably damage the lung parenchyma. Whenever the density of bacteria in the bronchial lumen is >or=10(6) CFU/mL, there is a high probability that the degree of inflammatory response will lead to a vicious cycle which in turn tends to sustain the process. This situation can arise during the clinical course of any acute exacerbation of CB, independently of its aetiology, provided the episode is sufficiently severe and/or prolonged. Fluoroquinolones of the third and fourth generation are bactericidal against most microorganisms usually related to acute exacerbations of CB. Their diffusion to bronchial mucus is adequate. When used in short (5-day) treatment they reduce the bacterial load in a higher proportion than is achieved by beta-lactam or macrolide antibiotics given orally. Although the clinical cure rate is similar to that obtained with other antibiotics, the time between exacerbations could be increased.

    Continuous positive airway pressure ventilation (CPAP) and non-invasive positive pressure ventilation (NPPV) are accepted treatments in acute cardiogenic pulmonary edema (ACPE) and acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The aim of the study was a comparison of effectiveness, safety, and management of NPPV in ACPE and AECOPD trying to find an approach for standard management in intensive care. Thirty patients with acute respiratory failure (14 due to ACPE, 16 due to AECOPD) were prospectively included into the study. If clinical stability could not be achieved by standard therapy (pharmacological therapy and oxygen) patients were treated by non-invasive ventilation (NPPV) using a BiPAP-Vision device in S/T-mode. During the first 90 min after the onset of NPPV respiratory and vital parameters were documented every 30 min. Additional relevant outcome parameters (need for intubation, duration of ICU stay, complications and mortality) were monitored. We found that 85.7% of the ACPE patients and 50.0% of the AECOPD patients were treated successfully with NPPV. Intubation rate was 31.2% in the AECOPD group and 14.3% in the ACPE group. 78.6% of the ACPE patients and 43.8% of the AECOPD patients were regularly discharged from hospital in a good condition. In the first 90 min of NIV, there was a significant amelioration of respiratory and other vital parameters. In ACPE patients there was a significant increase in PaO2 from 58.9 mmHg to 80.6 mmHg and of oxygen saturation (SaO2) from 85.1% to 93.1% without changing the inspiratory O2 concentration. This effect was comparable in the AECOPD group, but only could be achieved by increasing the inspiratory ventilation pressure. In the ACPE group inspiratory ventilation pressure could be reduced. In conclusion, in acute respiratory failure, ACPE patients comparably profit from NPPV as do patients with AECOPD, but the algorithm of titration for non-invasive ventilation pressure is different.

    Chronic obstructive pulmonary disease (COPD) is characterized by chronic incompletely reversible poor airflow and air trapping and usually this debilitating disorder limits the outside activities of the patients depriving them of sunlight which is a rich source of Vitamin D. The objective of this study was to determine the effect of vitamin D supplementation in reducing number of acute exacerbation in COPD patients. This randomized control trial was conducted at East Medical Ward Mayo Hospital Lahore from January to December 2015 as exacerbations of COPD are season dependent. Diagnosis was confirmed by performing Pulmonary Function Tests (PFTs). Basic demographical information was obtained and baseline PFTs of the patient was done. Only Group A patients was treated with oral vitamin D intake of 2000 IU daily for 6 months. Vitamin D level was measured at 0, 2, 4, and 6 months and exacerbation of COPD, FEV1 and FVC was measured weekly. Both the groups were given standard treatment for exacerbation of COPD. Spirometry was repeated at each visit. Blood samples were collected every 2 months for vitamin D. Supplementation was stopped if vitamin D level exceeded 100ng/ml. The mean age of the patients was 46.28±8.83 years, the male to female ratio was 1.8:1. The mean 25(OH) level at baseline was 24.08±2.58 and at 6th month was 29.60±8.74. The mean FVC at baseline was 77.83±5.49 and at 6th month was 91.34±5.52. The exacerbation at baseline was present in all 120(100%) patients and at 6th month was reduced to 4(3.3%). Vitamin D supplementation has significant effect in reducing number of acute exacerbation in COPD patients when it is given for prolonged period.

    The evidence on the acute effects of smoking on biomarkers is limited. Our aim was to study the acute effect of smoking on disease-related biomarkers. The acute effect of smoking on serum high sensitivity CRP (hs-CRP) and plasma fibrinogen and its association with disease severity was studied by challenging 31 chronic obstructive pulmonary disease patients with cigarette smoking and repeatedly measuring these biomarkers before and after smoking. Fibrinogen and hs-CRP increased directly after smoking by 9.4 mg/dl (95% CI: 4.2-14.5) and 0.13 mg/l (95% CI: 0.03-0.23), respectively. Fibrinogen levels remained elevated after 35 min, whereas hs-CRP normalized. Pearson's correlation coefficient between the hs-CRP change and chronic obstructive pulmonary disease severity was 0.25 (p = 0.06). Fibrinogen and hs-CRP increased directly after smoking in the chronic obstructive pulmonary disease patients. Their association with disease risk and/or progression remains to be demonstrated.

    A prospective observational study to investigate the distribution and antimicrobial resistance of pathogenic bacteria in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Beijing, China. Patients with AECOPD were recruited from 11 general hospitals. Sputum specimens were cultured and bacteria identified. Antibiotic susceptibility was determined for each isolate, and presence of antibiotic resistance genes was evaluated using polymerase chain reaction. Pathogenic bacteria were isolated from 109/318 patients (34.28%); 124 isolates of 22 pathogenic bacterial species were identified, including Klebsiella pneumoniae (16.94%), Pseudomonas aeruginosa (16.94%), Acinetobacter baumannii (11.29%), Streptococcus pneumoniae (8.87%), and Staphylococcus aureus (7.26%). S. aureus was sensitive to tigecycline, teicoplanin, vancomycin and linezolid but resistant to penicillin and levofloxacin. K.pneumoniae, P. aeruginosa, A. baumannii and E. coli were susceptible to amikacin and cefoperazone. K. pneumoniae and P. aeruginosa are the most common pathogenic bacteria in AECOPD cases in Beijing, China. Our antibiotic resistance findings may be helpful in selecting antibiotic therapy. © The Author(s) 2015.

    Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) have high mortality and health care costs. The platelet to lymphocyte ratio (PLR) is a marker of inflammation and has been reported to be elevated in patients with AECOPD compared to stable state. In this study, we sought to evaluate the association of the PLR in patients with AECOPD with 90-day mortality. We conducted a retrospective cohort study of patients admitted to our institution with a primary diagnosis of AECOPD between January 2014 and July 2014. Blood test results on admission were recorded. The primary outcomes were 90-day mortality. One hundred and eighty-one AECOPD patients were considered for the study. Death had occurred in 16 (9%) patients within 90 days of hospital discharge. Univariable analysis identified age, haemoglobin, neutrophil count, and urea level, neutrophil lymphocyte ratio (NLR) and PLR as being associated with increased 90-day mortality. Multivariable logistic regression analysis variables demonstrated that only PLR (P=0.03) was significantly associated with death at 90 days. Receiver operator characteristic analysis identified PLR ≥235 had a sensitivity of 63% and specificity of 74% in predicting 90-day mortality. PLR was ≥235 was also associated with worse survival (days) [mean ± standard deviation (SD): PLR ≥235 vs. PLR <235: 512±358 vs. 626±346, P=0.004]. A PLR ≥235 was significantly associated with 90-day mortality, which may provide prognostic guidance to clinicians.

    Currently, no consensus exists on the best treatment strategy for acute malignant left-sided colonic obstruction. This systematic review and meta-analysis aims to compare the outcomes following the two surgical treatment options; primary resection versus colostomy creation as bridge to surgery. This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to minimize risk of bias. Pubmed, Embase and Cochrane Library were searched for all relevant literature. Methodological quality of included studies was assessed using the MINORS criteria. Pooled odds ratios with 95% confidence intervals (95%CI) were calculated using random effects models. Eight comparative studies were included, reporting on 2424 patients; 1973 patients were treated with primary resection and 451 patients with colostomy construction followed by elective resection. Meta-analysis showed no significant differences between both treatment groups regarding 30-day mortality and morbidity (OR = 0.77, 95%CI 0.3-1.96 and OR = 0.76, 95%CI 0.51-1.13, respectively). However, patients treated with a colostomy followed by elective resection had significantly more primary anastomoses constructed and were less likely to be left with a permanent colostomy (OR = 0.17, 95%CI 0.11-0.26 and OR = 0.22, 95%CI 0.11-0.46, respectively). This systematic review provides an overview of all available literature on primary resection versus colostomy creation as bridge to surgery in patients with acute LSCO. Keeping the limitations of this study in mind, we conclude that a diverting colostomy as bridge to surgery is a safe and valid alternative for primary resection. Copyright © 2015 Elsevier Ltd.

Flow-mediated dilation (FMD, a valuable cardiovascular risk indicator, allows assessment of endothelial-dependent vasodilation, which is to a certain extent mediated by NO. We investigated the effects of hypercapnia and acid-base imbalance on endothelial-dependent vasodilation by measurement of FMD in 96 elderly patients with acute exacerbation of COPD.

    Full Text Available The effect of inhalation of ipratropium bromide was evaluated in 20 patients with bronchial asthma. It was observed that there was no significant improvement in the forced vital capacity and the forced expired volume in one second, while there was significant improvement in the peak expiratory flow rate (PEFR measured at 9 pm, after inhalation of 2 puffs of ipratropium bromide aerosol (0.02mg/puff three to four times a day for 2 weeks. Since PEFR is a measure of large airway function and cholinergic mechanisms are primarily involved for airflow obstruction at large airways, improvement in PEFR by ipratropium bromide highlights its role as a useful bronchodilator in patients in whom vagal reflexes are responsible for the provocation of bronchoconstriction.

    To evaluate the technical feasibility and clinical effectiveness of fluoroscopically guided placement of self-expandable metallic stents and stent-grafts for acute malignant colorectal obstruction. Radiologic images and clinical reports of 42 patients (22 men, 20 women; age range, 28-93 years; median age, 65.5 years) who underwent fluoroscopically guided colorectal stent insertion without endoscopic assistance for acute malignant obstruction were reviewed retrospectively. Eighteen patients received bare stents as a bridge to surgery. Twenty-four patients received 27 insertions of either a bare stent (n = 15) or a stent-graft (n = 12) for palliation. The obstruction was located in the rectum (n = 8), sigmoid (n = 17), descending colon (n = 8), splenic flexure (n = 3), and transverse colon (n = 6). Clinical success, defined as more than 50% dilatation of the stent with subsequent symptomatic improvement, was achieved in 41 of the 42 patients (98%). No major procedure-related complications occurred. Minor complications occurred in eight of the 45 procedures (18%). No perioperative mortalities occurred within 1 month after surgery. In the palliative group, the median stent patency was 62 days (range, 0-1,014 days). There was no statistically significant difference in stent patency between the bare stents (range, 0-855 days; median, 68 days) and stent-grafts (range, 1-1,014 days; median, 81 days). Fluoroscopically guided placement of self-expandable metallic stents and stent-grafts for the relief of acute malignant colorectal obstruction was technically feasible without endoscopic assistance-even in lesions proximal to the splenic flexure and transverse colon-and clinically effective in both bridge to surgery and palliative management.

    Full Text Available Abstract Introduction We were able to treat a patient with acute exacerbation of chronic obstructive pulmonary disease who also suffered from sleep-disordered breathing by using the average volume-assured pressure support mode of a Respironics V60 Ventilator (Philips Respironics: United States. This allows a target tidal volume to be set based on automatic changes in inspiratory positive airway pressure. This removed the need to change the noninvasive positive pressure ventilation settings during the day and during sleep. The Respironics V60 Ventilator, in the average volume-assured pressure support mode, was attached to our patient and improved and stabilized his sleep-related hypoventilation by automatically adjusting force to within an acceptable range. Case presentation Our patient was a 74-year-old Japanese man who was hospitalized for treatment due to worsening of dyspnea and hypoxemia. He was diagnosed with acute exacerbation of chronic obstructive pulmonary disease and full-time biphasic positive airway pressure support ventilation was initiated. Our patient was temporarily provided with portable noninvasive positive pressure ventilation at night-time following an improvement in his condition, but his chronic obstructive pulmonary disease again worsened due to the recurrence of a respiratory infection. During the initial exacerbation, his tidal volume was significantly lower during sleep (378.9 ± 72.9mL than while awake (446.5 ± 63.3mL. A ventilator that allows ventilation to be maintained by automatically adjusting the inspiratory force to within an acceptable range was attached in average volume-assured pressure support mode, improving his sleep-related hypoventilation, which is often associated with the use of the Respironics V60 Ventilator. Polysomnography performed while our patient was on noninvasive positive pressure ventilation revealed obstructive sleep apnea syndrome (apnea-hypopnea index = 14, suggesting that his chronic

    Many asthma patients seek alternative or adjunctive therapies. One such modality is reflexology, whereby finger pressure is applied to certain parts of the body. The aim of the study was to examine the popular claim that reflexology treatment benefits bronchial asthma. Ten weeks of active...... or simulated (placebo) reflexology given by an experienced reflexologist, were compared in an otherwise blind, controlled trial of 20+20 outpatients with asthma. Objective lung function tests (peak flow morning and evening, and weekly spirometry at the clinic) did not change. Subjective scores (describing...... diaries was carried out. It was accompanied by a significant pattern compatible with subconscious unblinding, in that patients tended to guess which treatment they had been receiving. No evidence was found that reflexology has a specific effect on asthma beyond placebo influence....

    Full Text Available Continuous positive airways pressure (CPAP is a well known and safe method of treatment patients with obstructive sleep apnoea syndrome (OSAS. The effects of CPAP administration on the upper respiratory tract are known. However its effects on the lower respiratory tract still needs to be determined. Studies on bronchial hyperreactivity in patients treated by CPAP are contradictory. The aim of the study was to assess the influence of a 3-week CPAP treatment in patients with OSAS and to evaluate associations between changes in bronchial reactivity and clinical features of OSAS and lung function tests (LFT. Patients with newly diagnosed OSAS and lack of infection or chronic illness of the respiratory tract or other conditions which could influence bronchial hyperreactivity (BHR were included. Investigations were performed in 101 patients. There were 88 males and 13 females, mean age 51.5±11.2 years and BMI 32.6±5.4 kg·m–2. Qualified patients were randomly divided into 2 groups: 76 patients to CPAP treatment group, 25 control group. Both groups did not differ in anthropometrics features, severity of OSAS and LFT. Metacholine challenge test (MchCT was performed at baseline and repeated after 3 weeks. Analysis of the individual results showed that in 11 patients the MchCT was positive (6 in the CPAP and 5 in the control groups. After 3 weeks in the group of CPAP treated patients an increase of BHR was noted. Log PC20M decreased from 1.38±0.3 to 1.26±0.5 (p<0.05. The number of patients with a positive result in the MchCT increased from 6 to 16 patients. There was no significant change in BHR in the control group. It was found that CPAP treated patients with BHR were older, had less severe OSAS and lower FEV1 (p<0.05. In none of the patients positive result of BHR did no affect compliance to CPAP treatment. Conclusions: CPAP therapy increases bronchial reactivity, but does not affect compliance to treatment.

  8. Colonic stenting as bridge to surgery versus emergency surgery for management of acute left-sided malignant colonic obstruction: a multicenter randomized trial (Stent-in 2 study

    2007-07-01

    Full Text Available Abstract Background Acute left-sided colonic obstruction is most often caused by malignancy and the surgical treatment is associated with a high mortality and morbidity rate. Moreover, these operated patients end up with a temporary or permanent stoma. Initial insertion of an enteral stent to decompress the obstructed colon, allowing for surgery to be performed electively, is gaining popularity. In uncontrolled studies stent placement before elective surgery has been suggested to decrease mortality, morbidity and number of colostomies. However stent perforation can lead to peritoneal tumor spill, changing a potentially curable disease in an incurable one. Therefore it is of paramount importance to compare the outcomes of colonic stenting followed by elective surgery with emergency surgery for the management of acute left-sided malignant colonic obstruction in a randomized multicenter fashion. Methods/design Patients with acute left-sided malignant colonic obstruction eligible for this study will be randomized to either emergency surgery (current standard treatment or colonic stenting as bridge to elective surgery. Outcome measurements are effectiveness and costs of both strategies. Effectiveness will be evaluated in terms of quality of life, morbidity and mortality. Quality of life will be measured with standardized questionnaires (EORTC QLQ-C30, EORTC QLQ-CR38, EQ-5D and EQ-VAS. Morbidity is defined as every event leading to hospital admission or prolonging hospital stay. Mortality will be analyzed as total mortality as well as procedure-related mortality. The total costs of treatment will be evaluated by counting volumes and calculating unit prices. Including 120 patients on a 1:1 basis will have 80% power to detect an effect size of 0.5 on the EORTC QLQ-C30 global health scale, using a two group t-test with a 0.05 two-sided significance level. Differences in quality of life and morbidity will be analyzed using mixed-models repeated measures

    Ogilvie's syndrome is acute colonic dilatation without organic obstacle in a previously healthy colon. Surgery is the only treatment of cases complicated by necrosis or perforation. In contrast, treatment of uncomplicated forms is not unanimous, and is the subject of this literature review. Determine the results of different therapeutic methods of uncomplicated forms of Ogilvie's syndrome in terms of efficiency of removal of colonic distension, recurrence, morbidity and mortality. Clarify their respective indications. An electronic literature search in the "MEDLINE" database, supplemented by hand searching on the reference lists of articles, was conducted for the period between 1980 and 2012. Conservative treatment is effective in 53 to 96% of cases with a risk of colonic perforation less than 2.5% and a mortality of 0 to 14% % (level of evidence 4, recommendation grade C). Neostigmine is effective in 64 to 91% of cases after a first dose, with a risk of recurrence of 0 to 38%. It remains effective in 40 to 100% of cases after a second dose (evidence level 2, grade recommendation B). Endoscopic decompression is a safe and effective technique with a success rate of 61 to 100% at the first attempt , a recurrence rate of 0 to 50%, a rate of colonic perforation less than 5% and a mortality less than 5% (level evidence 4, recommendation grade C). PEG may be recommended for the prevention of recurrence of the ACPO after successful treatment with neostigmine or endoscopic decompression (evidence level 2, recommendation grade B). The cecostomy is more effective and safer than conventional colostomy (level of evidence 4, recommendation grade C). The cecostomy is highly effective in colonic decompression but associated with a high mortality (level of evidence 4, recommendation grade C). Conservative treatment is recommended in first intention. In case of failure, neostigmine should be tried. If unsuccessful, the endoscopic decompression is proposed. The cecostomy is

    Aim: To determine the efficacy and usefulness of a chronic obstructive pulmonary disease (COPD) care bundle designed for the initial management of acute exacerbations of COPD and to assess whether it improves quality of care and provides better outcomes. Introduction: The level of care provided in the emergency department (ED) for COPD exacerbations varies greatly, and there is a need for a more systematic, consistent, evidence-based quality improvement approach to improve outcomes and costs. Methods: A prospective before and after study was carried out in a university teaching hospital. Fifty consecutive patients were identified in the ED with COPD exacerbations and their management was reviewed. Following the education of ED staff and the implementation of a COPD care bundle, the outcome for 51 consecutive patients was analyzed. This COPD care bundle consisted of ten elements considered essential to the management of COPD exacerbations and was scored 0–10 according to the number of items on the checklist implemented correctly. Results: Following implementation, the mean bundle score out of 10 improved from 4.6 to 7 (P,0.001). There was a significant decrease in the unnecessary use of intravenous corticosteroids from 60% to 32% (P=0.003) and also a marked improvement in the use of oxygen therapy, with appropriate treatment increasing from 76% to 96% (P=0.003). Prophylaxis for venous thromboembolism also improved from 54% to 73% (P=0.054). The 30-day readmission rate did not significantly improve. Conclusion: The use of a bundle improves the delivery of care for COPD exacerbations in the ED. There is more appropriate use of therapeutic interventions, especially oxygen therapy and intravenous corticosteroids.

    Full Text Available Introduction: Obstructive Sleep Apnea (OSA has been associated with an elevated risk of cardiac arrhythmia. Continuous positive airway pressure (CPAP is the selected treatment for moderate to severe OSA and could improve arrhythmias in the long term. However, the acute effect of CPAP has not been studied in detail. Methods: We conducted a prospective study with 25 patients with moderate to severe OSA diagnosed by home respiratory polygraphy (RP and arrhythmia and/or pauses in 24-hour Holter ECG. We analyzed inflammatory parameters and the rate of arrhythmias/pauses after 7 days of auto-adjusting CPAP. Results: 92.5% of the patients were men with a mean age of 61.7±1.9 years. Body mass index (BMI was 59.5±2.2 kg/m2, with a mean apnea hypopnea index (AHI of 37.7±3.8 events/hour (ev/h, and a residual AHI (AHIr of 5.3±0.53 ev/h. After short treatment with CPAP we observed a tendency to improvement in both the severity and number of ventricular extrasystoles (VE (1595.0±850.3 vs. 926.4±434.5 respectively, pauses and the inflammatory parameters (CRP 3.9±3.1 vs. 1.7±1.2, glycemia 131.4±11.6 vs. 121.9±9.8, HOMA 24.4±3.1 vs. 21.7±2.8, insulin 7.6±1.4 vs. 7.2±1.2 (p>0.5. Conclusion: We didn't find significant changes in pauses, VE and inflammatory parameters with CPAP short therapy in CPAP naive patients recently diagnosed with OSA.

    The efficacy and safety of self-expandable metallic stents (SEMSs) as a bridge for patients with acute malignant colorectal obstructions (AMCOs) are still controversial. We conducted this study to evaluate the outcomes of patients with AMCOs treated by different strategies. From January 2010 to March 2014, a total of 171 patients with AMCOs from Zhongshan Hospital were retrospectively enrolled in this study. One hundred twenty patients successfully received stent placement followed by one-stage laparoscopic or open resection in the stent group, and 51 patients received emergency operations in the emergency group. The operation duration and postoperative hospital stay were significantly shorter in the stent group (114.51 ± 28.65 vs. 160.39 ± 58.94 min, P stent group also had significantly reduced intraoperative blood loss and the incidence of postoperative complications compared with the emergency group (61.00 ± 43.70 vs. 121.18 ± 85.90 ml, P stent group was significantly longer than that in the emergency group (53 vs. 41 months, P = 0.034). In subgroup analysis of stent group, the stent laparoscopy group had significantly decreased postoperative complications (P = 0.025), and similar long-term survival (P = 0.81). Stent placement as a bridge to surgery is a safe and feasible procedure and provides significant advantages in terms of short-term outcomes and favorable prognoses for patients with AMCOs. Laparoscopic surgery could be considered as an optimal treatment after stent placement.

    To study if the coexistence of chronic obstructive pulmonary disease (COPD) in patients diagnosed with acute heart failure (AHF) at the emergency department (ED) has an impact on short- and long-term outcomes. The EAHFE-COPD study included patients who attended in 34 Spanish EDs for AHF. We compared patients with AHF plus COPD with patients with AHF in whom COPD was neither diagnosed nor excluded by functional respiratory tests (FRT). Outcome analysis included all-cause mortality, prolonged hospitalization, and ED revisit. Crude results were adjusted by differences between patients with and without COPD. We included 8099 patients with AHF, 2069 having COPD (25.6%; AHF-COPD-known). Compared with AHF-COPD-unknown, AHF-COPD-known differed in 20 variables. After adjusting for differences between the two groups, AHF-COPD-known patients showed no significant differences in 30-day mortality (OR=0.89; 95% CI=0.71-1.11), prolonged hospitalization in general wards (OR=1.04; 95% CI=0.89-1.22) or SSU (OR=1.38; 95% CI=0.97-1.97), and 1-year mortality (HR: 1.02; 95% CI=0.89-1.17), but showed a higher 30-day revisit rate (OR=1.32; 95% CI=1.13-1.54). In patients attending the ED for AHF, the coexistence of COPD is only associated with an increased risk of short-term ED revisit, but not prolonged hospitalization and short- or long-term mortality.

    Bronchopulmonary hygiene physical therapy is a form of chest physical therapy including chest percussion and postural drainage to remove lung secretions. These are applied commonly to patients with both acute and chronic airway diseases. Despite controversies in the literature regarding its efficacy, it remains in use in a variety of clinical settings. The various forms of this therapy are labour intensive and need to be evaluated. The objective of this review was to assess the effects of bronchial hygiene physical therapy in people with chronic obstructive pulmonary disease and bronchiectasis. We searched the Cochrane Airways Group trials register and reference lists of articles up to July 1997. We also wrote to study authors. Randomised trials in which postural drainage, chest percussion, vibration, chest shaking, directed coughing or forced exhalation technique was compared to other drainage or breathing techniques, placebo or no treatment. Two reviewers applied the inclusion and exclusion criteria on masked publications independently. They assessed the trial quality independently. Only data from the first arm of crossover trials were included. The seven included trials involved six comparisons and a total of 126 people. The trials were small and not generally of high quality. The results could not be combined as trials addressed different patient groups and outcomes. In most comparisons, bronchial hygiene physical therapy produced no significant effects on pulmonary function, apart from clearing sputum in chronic obstructive pulmonary disease and in bronchiectasis. There is not enough evidence to support or refute the use of bronchial hygiene physical therapy in people with chronic obstructive pulmonary disease and bronchiectasis.

Despite controversies in the literature regarding its efficacy, it remains in use in a variety of clinical settings. The various forms of this therapy are labour intensive and need to be evaluated. The objective of this review was to assess the effects of bronchial hygiene physical therapy in people with chronic obstructive pulmonary disease and bronchiectasis. We searched the Cochrane Airways Group trials register and reference lists of articles up to January 2007. We also wrote to study authors. Randomised trials in which postural drainage, chest percussion, vibration, chest shaking, directed coughing or forced exhalation technique was compared to other drainage or breathing techniques, placebo or no treatment. Two reviewers applied the inclusion and exclusion criteria on masked publications independently. They assessed the trial quality independently. Only data from the first arm of crossover trials were included. The seven included trials involved six comparisons and a total of 126 people. The trials were small and not generally of high quality. The results could not be combined as trials addressed different patient groups and outcomes. In most comparisons, bronchial hygiene physical therapy produced no significant effects on pulmonary function, apart from clearing sputum in chronic obstructive pulmonary disease and in bronchiectasis. An update search carried out in January 2007 did not identify any new studies for inclusion. There is not enough evidence to support or refute the use of bronchial hygiene physical therapy in people with chronic obstructive pulmonary disease and bronchiectasis.

    The aim of this study was to compare the prognostic significance of microvascular obstruction (MO) and persistent microvascular obstruction (PMO) as assessed by cardiac magnetic resonance (CMR) in patients with acute myocardial infarction (AMI). CMR was performed in 184 patients within the week following successfully reperfused first AMI. First-pass images were performed to evaluate extent of MO and late gadolinium-enhanced images to assess PMO and infarct size (IS). Major adverse cardiac events (MACE) were collected at 1-year follow-up. MO and PMO were found in 127 (69%) and 87 (47%) patients, respectively. By using univariate logistic regression analysis, high Global Registry of Acute Coronary Events (GRACE) risk score (odds ratio [OR] 95% confidence interval [CI]: 3.6 [1.8-7.4], p < 0.001), IS greater than 10% (OR [95% CI]: 2.7 [1.1-6.9], p = 0.036), left ventricular ejection fraction less than 40% (OR [95% CI]: 2.4 [1.1-5.2], p = 0.027), presence of MO (OR [95% CI]: 3.1 [1.3-7.3], p = 0.004) and presence of PMO (OR [95% CI]:10 [4.1-23.9], p < 0.001) were shown to be significantly associated with the outcome. By using multivariate analysis, presence of MO (OR [95% CI]: 2.5 [1.0-6.2], p = 0.045) or of PMO (OR [95% CI]: 8.7 [3.6-21.1], p < 0.001), associated with GRACE score, were predictors of MACE. Presence of microvascular obstruction and persistent microvascular obstruction is very common in AMI patients even after successful reperfusion and is associated with a dramatically higher risk of subsequent cardiovascular events, beyond established prognostic markers. Moreover, our data suggest that the prognostic impact of PMO might be superior to MO. (orig.)

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB.

    BACKGROUND: Hepatic sinusoidal obstruction syndrome (SOS) during treatment of childhood acute lymphoblastic leukemia (ALL) has mainly been associated with 6-thioguanine. The occurrence of several SOS cases after the introduction of extended pegylated asparaginase (PEG-asparaginase) therapy...... in the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol led us to hypothesize that PEG-asparaginase, combined with other drugs, may trigger SOS during 6-thioguanine-free maintenance therapy. PROCEDURE: In children with ALL treated in Denmark according to the NOPHO ALL2008 protocol...... children receiving PEG-asparaginase biweekly, 29 developed SOS (≥2 criteria: hyperbilirubinemia, hepatomegaly, ascites, weight gain ≥2.5%, unexplained thrombocytopenia

    To explore the proportion and prevention status of venous thromboembolism (VTE) among hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Beijing. Based on a multi-center retrospective study, a total of 636 hospitalized AECOPD patients from 17 class 2/3 hospitals in Beijing were examined from September 1, 2011 to March 31, 2012. They fulfilled one of the following criteria: respiratory failure type II, on invasive or non-invasive mechanical ventilation, hospitalization for pulmonary infection, bedridden duration ≥ 3 days and congestive heart failure. All investigators received standardized training and used a standardized questionnaire to collect data on VTE risk factors, the diagnosis of VTE and the utilization of VTE prophylaxis. According to Caprini score, they were categorized into 3 groups of lower risk (Caprini score ≤ 3), moderate risk (Caprini score 4-6) and high risk ( ≥ 7) to compare the intergroup differences in the VTE proportion and the utilization of VTE prophylaxis. A total of 636 patients were assessed. There were 416 males and 220 females with a mean (SD) age of 74.9 ± 9.3 years. Among them, 133 patients received lower extremity venous ultrasonic examination and 92 were diagnosed with deep venous thrombosis (DVT) including 2 patients with pulmonary thromboembolism (PTE). Thus the overall incidence of VTE was 14.5% (92/636) and increased with age (Ptrend = 0.044). The proportion of VTE in asymptomatic patients was higher in those symptomatic ones (21.1% vs 8.0%, P = 0.000). And it was the highest in high risk group, followed by lower risk and moderate risk groups at 17.9% (14/78), 16.0% (26/163) and 13.2% (52/395) respectively, There was no statistical significance (P = 0.450 for group difference, Ptrend = 0.946). Among 544 patients without VTE, only 19.1% (104/544) employed the pharmacologic and/or mechanical methods for preventing VTE. The prevention proportion gradually increased with rising

    The acute effects of terbutaline (T) and breathing 100% O/sub 2/(O/sub 2/) on gas exchange, pulmonary hemodynamics and radionuclide angiography were evaluated in 15 patients with severe chronic obstructive pulmonary disease (COPD). O/sub 2/ breathing resulted in a decrease in mean pulmonary artery pressure (PAP) and cardiac index (CI) without changing pulmonary vascular resistance index (PVRI) or right and left ventricular ejection fractions (RVEF,LVEF). On the other hand, T administration was followed by a decrease in PVRI, and increase in CI, RVEF and LVEF. These effects of T were maintained during exercise. Although RVEF was inversely correlated with basal levels of PAP or PVRI, acute changes in pulmonary hemodynamics were not correlated with significant changes on RVEF. These results suggest that T may be useful in the treatment of patients with COPD prone to develop cor pulmonale. However, the long-term benefit of this treatment remains to be established.

    Traditionally, assessments of the bronchial dose from radon progeny were carried out by measuring the unattached fraction (f{sub p}) of potential alpha energy concentration (PAEC), the total PAEC, activity median diameters (AMDs) and equilibrium factor, and then using dosimetric lung models. A breakthrough was proposed by Hopke et al. (1990) to use multiple metal wire screens to mimic the deposition properties of radon progeny in the nasal (N) and tracheobronchial (T-B) regions directly. In particular, they were successful in using four layers of 400-mesh wire screens with a face velocity of 12 cm s{sup -1} for the simulation of radon progeny deposition in the T-B region. Oberstedt and Vanmarcke (1995) carried out precise calibrations for the system, and named the system as the 'bronchial dosimeter'. Based on these, Yu and Guan (1998) proposed a portable bronchial dosimeter similar to a normal measurement system for radon progeny or PAEC and consisted of only a single sampler and employed only one 400-mesh wire screen and one filter. However, all these 'bronchial dosimeters' in fact only determined the fraction of potential alpha energy from radon progeny deposited in the T-B region, which required certain assumptions and calculations to further give the final bronchial dose. In the present work, a true 'bronchial dosimeter' was designed, which consisted of three 400-mesh wire screens and a filter. With a face velocity of 11 cm s{sup -1}, the deposition pattern on the wire screens was found to satisfactorily match the variation of the dose conversion factor (in the unit of mSv/WLM) with the size of radon progeny from 1 to 1000 nm. In this way, this bronchial dosimeter directly gave the bronchial dose from the alpha counts recorded on the wire-screens and the filter paper. With the development of this bronchial dosimeter, the present practice of 'dose estimation' from large-scale radon surveys can be replaced by large

    In patients with post-tuberculosis bronchial stenosis (PTBS), the severity of bronchial stenosis affects the restenosis rate after the silicone stent is removed. In PTBS patients with incomplete bronchial obstruction, who had a favorable prognosis, the timing of stent removal to ensure airway patency is not clear. We evaluated the time for silicone stent removal in patients with incomplete PTBS. A retrospective study examined PTBS patients who underwent stenting and removal of a silicone stent. Incomplete bronchial stenosis was defined as PTBS other than total bronchial obstruction, which had a luminal opening at the stenotic segment on bronchoscopic intervention. The duration of stenting was defined as the interval from stent insertion to removal. The study included 44 PTBS patients and the patients were grouped at intervals of 6 months according to the duration of stenting. Patients stented for more than 12 months had a significantly lower restenosis rate than those stented for less than 12 months (4% vs. 35%, P = 0.009). Multiple logistic regression revealed an association between stenting for more than 12 months and a low restenosis rate (odds ratio 12.095; 95% confidence interval 1.097-133.377). Moreover, no restenosis was observed in PTBS patients when the stent was placed more than 14 months previously. In patients with incomplete PTBS, stent placement for longer than 12 months reduced restenosis after stent removal.

    The authors studied regional pulmonary function after treatment with bronchial plastic surgery for bronchial lesion from bronchial tuberculosis and with irradiation for bronchial lesion from carcinoma using positron emission tomography and Tc-MAA. Six patients with bronchial tuberculosis and 6 with bronchogenic carcinoma were examined. Two of the 6 bronchial tuberculosis patients were examined before and after surgery. In all 6 patients with bronchial tuberculosis, ventilation and alveolar volume were recovered with improvement of bronchial lesion. In 2 patients examined before and after surgery, lung function of the normal disease-free side became worse after surgery. This phenomenon was explained by the fact that the compensated pulmonary function of contra lateral lung due to decreased function of the diseased side returned to normal function with improvement of the diseased lung. On the other hand, the regional pulmonary function did not improve in 2 patients with main bronchial lesion from bronchogenic carcinoma, even if atelectasis of the diseased lung was improved by irradiation. However, the regional pulmonary function was improved with the recovery of bronchial obstruction in lobar atelectasis by carcinoma. The difference of the results depended on whether pulmonary blood flow disturbance existed or not. If pulmonary blood flow disturbance was severe, ventilatory function was not recovered due to the mechanism of maintaining the ventilation-perfusion equilibrium. (author)

    Small bowel obstruction (SBO) is a common indication for emergency laparotomy in the UK, which is associated with a 90-day mortality rate of 13%. There are currently no UK clinical guidelines for the management of this condition. The aim of this multicentre prospective cohort study is to describe the burden, variation in management and associated outcomes of SBO in the UK adult population. UK hospitals providing emergency general surgery are eligible to participate. This study has three components: (1) a clinical preference questionnaire to be completed by consultants providing emergency general surgical care to assesses preferences in diagnostics and therapeutic approaches, including laparoscopy and nutritional interventions; (2) site resource profile questionnaire to indicate ease of access to diagnostic services, operating theatres, nutritional support teams and postoperative support including intensive care; (3) prospective cohort study of all cases of SBO admitted during an 8-week period at participating trusts. Data on diagnostics, operative and nutritional interventions, and in-hospital mortality and morbidity will be captured, followed by data validation. This will be conducted as a national audit of practice in conjunction with trainee research collaboratives, with support from patient representatives, surgeons, anaesthetists, gastroenterologists and a clinical trials unit. Site-specific reports will be provided to each participant site as well as an overall report to be disseminated through specialist societies. Results will be published in a formal project report endorsed by stakeholders, and in peer-reviewed scientific reports. Key findings will be debated at a focused national meeting with a view to quality improvement initiatives. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To compare the diagnostic and prognostic value of mid-regional pro-ANP (MR-proANP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with acute dyspnea. MR-proANP and NT-proBNP were measured with commercial immunoassays at hospital admission (n = 313), on day 2 (n = 234), and before discharge (n = 91) and compared for diagnosing acute heart failure (HF; n = 143) and to predict mortality among patients with acute HF and acute exacerbation of chronic obstructive pulmonary disease (AECOPD; n = 84) separately. The correlation coefficient between MR-proANP and NT-proBNP was 0.89 (p < 0.001) and the receiver-operating area under the curve was 0.85 (95% CI 0.81-0.89) for MR-proANP and 0.86 (0.82-0.90) for NT-proBNP to diagnose acute HF. During a median follow-up of 816 days, mortality rates were 46% in acute HF patients and 42% in AECOPD patients. After adjustment for other risk variables by multivariate Cox regression analysis, MR-proANP and NT-proBNP concentrations were associated with mortality in patients with acute HF, but only MR-proANP were associated with mortality among patients with AECOPD: hazard ratio ( ln MR-proANP) 1.98 (95% CI 1.17-3.34). MR-proANP and NT-proBNP concentrations provide similar diagnostic and prognostic information in patients with acute HF. In contrast to NT-proBNP, MR-proANP measurements also provided independent prognostic information in AECOPD patients.

    Quadriplegia is a severe, catastrophic injury that predominantly affects people early in life, resulting in lifelong physical disability. Obstructive sleep apnoea is a direct consequence of quadriplegia and is associated with neurocognitive deficits, sleepiness and reduced quality of life. The usual treatment for sleep apnoea is nasal continuous positive airway pressure (CPAP); however, this is poorly tolerated in quadriplegia. To encourage patients to use this therapy, we have to demonstrate that the benefits outweigh the inconvenience. We therefore propose a prospective, multinational randomized controlled trial of three months of CPAP for obstructive sleep apnoea after acute quadriplegia. Specialist spinal cord injury centres across Australia, New Zealand, the UK and Canada will recruit medically stable individuals who have sustained a (new) traumatic quadriplegia (complete or incomplete second cervical to first thoracic level lesions). Participants will be screened for obstructive sleep apnoea using full, portable sleep studies. Those with an apnoea hypopnoea index greater than 10 per hour will proceed to an initial three-night trial of CPAP. Those who can tolerate CPAP for at least 4 hours on at least one night of the initial trial will be randomized to either usual care or a 3-month period of auto-titrating CPAP. The primary hypothesis is that nocturnal CPAP will improve neuropsychological functioning more than usual care alone. The secondary hypothesis is that the magnitude of improvement of neuropsychological function will be predicted by the severity of baseline sleepiness measures, sleep fragmentation and sleep apnoea. Neuropsychological tests and full polysomnography will be performed at baseline and 3 months with interim measures of sleepiness and symptoms of autonomic dysfunction measured weekly. Spirometry will be performed monthly. Neuropsychological tests will be administered by blinded assessors. Recruitment commenced in July 2009. The results of

    To investigate the ability of the HEART score to predict the presence of obstructive coronary artery disease (CAD) determined by coronary computed tomography angiography (CCTA) and its ability to predict the occurrence of major adverse cardiac events (MACE) in patients referred for CCTA after emergency department (ED) presentation. From December 2011 to August 2014, 710 ED patients with chest pain who underwent CCTA within 30 days were included. The HEART score was retrospectively calculated and patients were followed for MACE, comprised of death, myocardial infarction, and revascularization. Association of CAD at CCTA in the different categories of the HEART score was analyzed using χ test. The performance of the HEART score in discriminating between those with and without obstructive CAD was evaluated by receiver operating characteristics. Kaplan-Meier analysis was used to assess MACE-free survival stratified by HEART-score categories. During median follow-up of 826 days (interquartile range: 563-1056), MACE occurred in 46 (6.5%) patients; 3 (0.4%) myocardial infarction, 8 (1.1%) death, and 36 (5.1%) revascularizations. A low HEART score was a significant predictor for MACE-free survival (P = 0.010). CCTA revealed obstructive CAD in 11.7% of patients, with no significant difference between patients with a low and intermediate/high HEART score, respectively 10.7% and 13.2% (P = 0.29). The ability of the HEART score to identify obstructive CAD was poor with an AUC of the receiver operating characteristics curve of 0.53. The HEART score does not adequately identify patients with obstructive CAD at CCTA. It does however predict occurrence of MACE in medium-term follow-up. Excluding patients from additional testing based solely on a low HEART score may lead to suboptimal patient management. CCTA had important implications on patient management and may be a more appropriate tool to further stratify risk in ED chest pain patients.

    Background. To date, bronchial diverticula have generally been treated as a pathological condition associated with chronic obstructive pulmonary disease (COPD), although only a limited amount of published information is available on the relationship between bronchial diverticula as depicted by multidetector computed tomography (MDCT) and airflow limitations. Purpose. To evaluate the relationship between airflow limitations and main bronchial diverticula in the subcarinal region using spirometry and thin-section MDCT. Material and Methods. A total of 189 consecutive adult patients were retrospectively evaluated based on spirometry and thin-section MDCT of the chest. All examinations were performed at our institution between June and October 2008. The study group included 70 women and 119 men with a mean age of 65 years (range 19-86 years). The relationship between the FEV1% and bronchial diverticula in the subcarinal region was analyzed (Student's t-test). Results. The indications for conducting the examinations were pulmonary diseases (82 patients), cardiovascular diseases (22), extrapulmonary malignancies (74), and other conditions (11). A total of 84/189 (44.4%) patients showed bronchial diverticula, and the FEV 1 % of 70/84 (83.3%) patients was above 70. The FEV 1 % of patients with lesions ranged from 26.0 to 97.8 (mean 76.8), whereas the range was 28.1-94.4 (mean 73.7) in those without lesions. There was no significant association between the FEV 1 % and the presence of subcarinal bronchial diverticula (P > 0.05). Conclusion. Our data demonstrate that thin-section chest CT commonly demonstrates main bronchial diverticula in the subcarinal region in patients without airflow limitations. We propose that the presence of a small number of tiny bronchial diverticula under the carina may not be a criterion for the diagnosis of COPD

    para disminuir las emisiones vehicularesOBJECTIVE: To identify the relationship between emergency visits for acute respiratory illnesses, acute bronchial asthma crisis (ABAC and acute respiratory infections (ARI, in children less than 14 years of age, and the daily changes of air pollutant levels, in two central hospitals of Havana City, between October 1st 1996 and March 16 1998. MATERIAL AND METHODS: An ecological time series study was conducted. We assessed the relationship between the presence of acute respiratory illnesses, ABAC, and IRA, and exposure to levels of particles less than 10 µg/m³ (PM10, smoke, and sulfur dioxide (SO2; negative binomial regression models were used to assess latency periods of one to five days as well as the cumulative effect of seven days before the emergency visit. RESULTS: The levels of atmospheric pollutants were low, in general. The 24-hour mean values for PM10 levels, smoke, and SO2, were 59.2 µg/m³ (SD=29.2, 27.7 µg/m³ (SD=21.2, and 21.1 µg/m³ (SD=20.1, respectively. An increase of 20 µg/m³ in the daily average of black smoke was associated with a 2.2% increase (95% CI 0.9-3.6 in the number of emergency visits for ABAC. A 20µg/m³ increase in the daily average of black smoke and SO2 was associated with an increase in ARI of 2.4% (95% CI 1.2-3.6, and 5% (95% CI 1.3-5.3, respectively, with a 5-day lag. We also ob served a cumulative effect for all the contaminants studied. CONCLUSIONS: These results suggest that air pollution levels in Havana City affect children's respiratory health; therefore implementation of control measures is necessary, especially those aimed at decreasing motor vehicle exhaust fumes

    Full Text Available Bronchial asthma is a prevalent chronic allergic disease of lungs at early ages. A priority  task in allergology  is to search  biological  markers  related  to uncontrolled atopic  bronchial asthma. Cytokines fulfill their distinct function in pathogenesis of atopic  bronchial asthma, participating at the initiation, development and persistence of allergic inflammation in airways, causing different  variations of clinical course of the disease (with  respect  to its acuteness, severity, frequency of exacerbations. The  present  work has studied  indices  of cellular  and  humoral links of immunity, as well as levels of some  pro and  anti-inflammatory cytokines in peripheral blood serum (IL-4, IL-10, IL-2 and TNFα, aiming to determine potential markers of uncontrolled atopic bronchial asthma in children. A group of Caucasian (European children was involved into the research: Cohort 1, moderate atopic  bronchial asthma with controlled course during the last 3 months (n = 59; Cohort 2, severe/moderate-severe atopic bronchial asthma with uncontrolled course of the disease within last 3 months (n = 51,  Cohort 3 – control, practically healthy  children without signs of atopy  (n = 33. All the  children included in the group with atopic  bronchial asthma underwent regular mono/combined basic therapy  at high/ intermediate therapeutic doses.  We performed a comparative analysis  of cell  population indices  reflecting certain cellular  immunity links,  and  determined significantly  lower  levels of CD3+   lymphocytes, as well as decrease in relative  and  absolute  contents of CD4+  and  CD8+  cells in the  cohort with  uncontrolled course of atopic  bronchial asthma, as compared with controlled-course cohort. When  evaluating concentrations  of cytokines in peripheral blood serum of the patients with controlled and uncontrolled atopic  bronchial asthma, we revealed  significantly  higher

    Comparative studies were made of 47 patients suffering from histologically and cytologically confirmed bronchial carcinoma, using CT and MRT respectively. CT examinations were performed before and after intravenous administration of contrast medium, whereas the MR examinations were conducted via EEG-triggered T 1 and T 2 marked SE sequences in the axial and coronary planes. Both methods were assessed in respect of tumour visualisation and documentation of tumour spread. Staging of tumour and lymph nodes yielded largely concurring results for CT and MRT. Exceptions were seen in 7 of 10 patients with malignant involvement of the pericardium and in 3 of 27 patients with lymph node metastases located mediastinally and subcarinally where only MRT showed a positive involvement of the pericardium or lymph nodes (with possible consequences for the staging of the tumour or lymph nodes). Decisive advantages of MRT compared with CT were seen in the identification of infiltration of the aortic-wall, in the differentiation of the poststenotic syndrome, in the visualisation of the thoracic wall infiltration and functional information on blood flow rate in upper venolus obstruction caused by a carcinoma.

    To explore the experiences of patients with chronic obstructive pulmonary disease and their family members relating both to participation in care during hospitalisation for an acute exacerbation in chronic obstructive pulmonary disease, and to the subsequent day-to-day care at home. When recovering from an exacerbation, the challenges associated with an unpredictable health condition dominate everyday life for patients and can involve their family members. Proper patient and family participation in care during discharge and follow-up can help patients to improve self-management. However, knowledge of the significance of patient and family participation for recovery and subsequent everyday life is still limited. This study adopted a longitudinal design informed by ethnographic fieldwork principles. Participant observations and interviews with 15 patients and 12 family members were conducted on a Danish hospital ward and twice at the participants' homes. A phenomenological-hermeneutic approach inspired by Ricoeur's theory of interpretation guided the data analysis. Participation in care was perceived as valuable, but could be associated with tensions and increased uncertainty. While patients mostly demonstrated a reactive approach to care, family members strived to be more proactive. In hospital, preparing for discharge included an effort to find a balance between powerlessness and influence during interactions with healthcare professionals. At home, managing further recovery and self-management were characterised by navigating between mutual pressure and consideration within the family. Family members play an important role in ensuring that patients are seen, heard and understood, but want to be acknowledged more by healthcare professionals. Appropriate interactions with healthcare professionals are crucial in order to support discharge and daily self-management. Knowledge of the challenges that patients with chronic obstructive pulmonary disease and their family

    Few studies have compared the ability of cardiac magnetic resonance (CMR) with that of scintigraphy using 201-thallium (201-Tl) and 99m-technetium pyrophosphate (99m-Tc PYP) to evaluate microvascular obstructions (MOs). In the present study the relationship between the scintigraphic and CMR characteristics of MOs after acute myocardial infarction (MI) was examined. The 14 patients (age 69±8 years, 11 males) underwent 201-Tl/99m-Tc PYP single photon emission computed tomography (SPECT) 7±3 days, initial CMR 16±12 days, and follow-up CMR 193±20 days after a reperfused first acute MI. Each image was analyzed using a 17-segment model. Segmental extent of delayed enhancement (DE), wall motion (WM) and degree of 201-Tl uptake were scored in 238 segments. Of 91 MI segments, MO was recognized in 22 (25%) segments on CMR. WM was significantly better in proportion to 201-Tl uptake (P=0.01) in MO segments. All 8 MO segments with WM improvement at follow-up had 99m-Tc PYP uptake, although only 3 (21%) of 14 MO segments that did not show WM improvement at follow-up had 99m-Tc PYP uptake (P=0.001). 99m-Tc PYP and 201-Tl scintigraphy have the potential to predict WM status and improvement of the MO region after reperfused acute MI.

    The employment of systemic corticosteroids in the treatment of acute exacerbations of chronic obstructive pulmonary disease (COPD) has been shown to improve airway limitation, decrease treatment failure and risk of relapse, and may improve symptoms in addition to decreasing the length of hospital stay. Nowadays, all clinical guidelines recommend systemic corticosteroids to treat moderate or severe COPD exacerbations. However, their use is associated with potential side effects, mainly hyperglycemia. In the era of precision medicine, the possibility of employing blood eosinophil count has emerged as a potential way of optimizing therapy. Issues regarding the intra-individual variability of blood eosinophil count determination, a lack of clear data regarding the real prevalence of eosinophilic acute exacerbations, the fact that previously published studies have demonstrated the benefit of systemic corticosteroids irrespective of eosinophil levels, and especially the fact that there is only one well-designed study justifying this approach have led us to think that we are not ready to use eosinophil count to guide treatment with systemic corticosteroids during acute exacerbations of COPD.

    Acute exacerbations in chronic obstructive pulmonary disease (AECOPD) are associated with increased mortality, rate of hospitalization, use of healthcare resources, and have a negative impact on disease progression, quality of life and lung function of patients with chronic obstructive pulmonary disease (COPD). There is an imperative need to homogenize the definition of AECOPD because the incidence of exacerbations has a significant influence or implication on treatment decision making, particularly in pharmacotherapy and could impact the outcome or change the statistical significance of a therapeutic intervention in clinical trials. In this review, using PubMed searches, we have analyzed the weaknesses and strengths of the different used AECOPD definitions (symptom-based, healthcare-based definition or the combinations of both), as well as the findings of the studies that have assessed the relationship of different biomarkers with the diagnosis, etiology and differential diagnosis of AECOPD and the progress towards the development of a more precise definition of COPD exacerbation. Finally, we have proposed a simple definition of AECOPD, which must be validated in future clinical trials to define its accuracy and usefulness in daily practice.

    Full Text Available Background: Self-expanding metallic stents (SEMS have been acknowledged in management of acute colorectal obstruction. The surgical approach after SEMS insertion varies from open approach to laparoscopic-assisted approach. The primary objective of this study was to compare the outcomes of laparoscopic approach and open approach after SEMS insertion. Methods: From January 2007 to December 2010, cross-sectional medical records reviewed a total of 76 patients who underwent colorectal stenting with SEMS. Patients and tumor characteristics, complications, morbidity and mortality were obtained. Results: Forty-three patients underwent SEMS placement as a bridge to surgery. Laparoscopic-assisted surgery (LS was performed in 24 patients (55.8%, and open surgery (OS was performed in 19 patients (44.2%. All clinicopathological parameters were matched. The technical success of SEMS was found in 42 patients (97.7%, and the clinical stent success was 100%. LS had a higher chance of primary anastomosis than OS (p=0.012; Odd ratio 2.717; 95%CI: 1.79-4.012. LS had a lower permanent ostomy rate (p=0.031; Odd ratio 0.385; 95%CI: 0.259-0.572 and lower estimated blood loss (p=0.024; Odd ratio 0.23; 95%CI: 0.006-0.086. The post-operative complications, mortality rate, recurrence rate, disease free status, and overall survival rates between the two groups were non-significant. Conclusion: Colonic stent is an effective treatment of acute malignant colonic obstruction. The authors suggest the advantage of laparoscopic approach resection after colonic stenting results in a higher primary anastomosis rate, and lower blood loss than open surgery.

    Objectives The shape of the flow-volume (F-V) curve is known to change to showing a prominent plateau as stenosis progresses in patients with tracheal stenosis. However, no study has evaluated changes in the F-V curve according to the degree of bronchial stenosis in patients with unilateral main bronchial stenosis. Methods We performed an analysis of F-V curves in 29 patients with unilateral bronchial stenosis with the aid of a graphic digitizer between January 2005 and December 2011. Results The primary diseases causing unilateral main bronchial stenosis were endobronchial tuberculosis (86%), followed by benign bronchial tumor (10%), and carcinoid (3%). All unilateral main bronchial stenoses were classified into one of five grades (I, ≤25%; II, 26%-50%; III, 51%-75%; IV, 76%-90%; V, >90% to near-complete obstruction without ipsilateral lung collapse). A monophasic F-V curve was observed in patients with grade I stenosis and biphasic curves were observed for grade II-IV stenosis. Both monophasic (81%) and biphasic shapes (18%) were observed in grade V stenosis. After standardization of the biphasic shape of the F-V curve, the breakpoints of the biphasic curve moved in the direction of high volume (x-axis) and low flow (y-axis) according to the progression of stenosis. Conclusion In unilateral bronchial stenosis, a biphasic F-V curve appeared when bronchial stenosis was >25% and disappeared when obstruction was near complete. In addition, the breakpoint moved in the direction of high volume and low flow with the progression of stenosis. PMID:26045916

    Despite the wide acceptance of the hepatobiliary scintigraphy as a popular diagnostic imaging modality for gallbladder and hepatobiliary disease, correlation between radionuclide diagnoses and the final clinical and/or pathologic findings have not been thoroughly evaluated. The lack of correlative studies frequently generates difficulties in making appropriate diagnostic interpretation of the objective findings. A retrospective clinical pathological and surgical correlative study was undertaken by the authors in 138 male veteran patients, who underwent computer assisted minute by minute Tc-99m DISIDA cholescintigraphy. A very high percentage (75%) revealed abnormalities; non-visualization of gallbladder (GB) with normal choledochus system (46%), choledochal obstruction with no GB visualization (13%), choledochal obstruction with normal GB visualization (6%), severe hepatocellular disease with non-diagnostic GB (4%), and delayed GB visualization (longer than 60 minutes) (3%). Non-visualization of GB but normal choledochus demonstrated diverse pathologic etiologies, acute and chronic cholecystitis (64%), S/P cholecystectomy (8%), functional obstruction secondary to sepsis or pancreatitis (6%), and various other pathologies including porcelain GB and cholangitis (22%). The most important cause of choledochal obstruction was mass lesions or local infiltration with metastases (33%) rather than acute cholecystitis (27%). Although the sensitivity (98%) and specificity (92%) for cystic duct obstruction were very high, the specificity decreases significantly for cholecystitis

    Thirteen bronchial arterial perfusion studies were performed in a total of 13 patients with lung tumors (11 cases of lung cancer, one metastatic tumor and one abscess), utilizing 99m TcO 4 - or 99m Tc-labeled macroaggregated albumin ( 99m Tc-MAA). Regions of interest (ROI) of the same size were set over areas of tumor, the mediastinum and healthy lung areas, and each ROI count was calculated by a nuclear medicine computer during an acquisition time period of 20 min with each tracer for 7 min to evaluate tumor part perfusion. The count ratios of tumor to healthy parts ranged from 1.7 to 6.5 (mean±s.d.; 3.8±1.9) in the 99m TcO 4 - group (10 patients) and from 130 to 230 (mean±s.d.; 163±30) in the 99m Tc-MAA group (3 patients), respectively. Tumor reduction rates 2 weeks after CDDP bronchial artery infusion therapy correlated positively to the count ratio in the 99m TcO 4 - lung cancer group, although significant correlation was not obtained. This study suggests that bronchial arterial infusion of anticancer agents may result in higher concentrations of anticancer agents in the tumors than with systemic chemotherapy and chemoembolic materials may exert more potent anticancer effects on tumors than nonparticulated anticancer agents.

    Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany. The odds ratios were adjusted for age and sex for all comorbidities for patients with asthma vs. without asthma. Bronchial asthma was strongly associated with allergic and with a lesser extent to non-allergic comorbidities: OR 7.02 (95%CI:6.83-7.22) for allergic rhinitis; OR 4.98 (95%CI:4.67-5.32) allergic conjunctivitis; OR 2.41 (95%CI:2.33-2.52) atopic dermatitis; OR 2.47 (95%CI:2.16-2.82) food allergy, and OR 1.69 (95%CI:1.61-1.78) drug allergy. Interestingly, increased ORs were found for respiratory diseases: 2.06 (95%CI:1.64-2.58) vocal dysfunction; 1.83 (95%CI:1.74-1.92) pneumonia; 1.78 (95%CI:1.73-1.84) sinusitis; 1.71 (95%CI:1.65-1.78) rhinopharyngitis; 2.55 (95%CI:2.03-3.19) obstructive sleep apnea; 1.42 (95%CI:1.25-1.61) pulmonary embolism, and 3.75 (95%CI:1.64-8.53) bronchopulmonary aspergillosis. Asthmatics also suffer from psychiatric, metabolic, cardiac or other comorbidities. Myocardial infarction (OR 0.86, 95%CI:0.79-0.94) did not coexist with asthma. Based on the calculated chances of manifestation for these comorbidities, especially allergic and respiratory, to a lesser extent also metabolic, cardiovascular, and mental disorders should be taken into consideration in the diagnostic and treatment strategy of bronchial asthma. PREVALENCE OF CO-EXISTING DISEASES IN GERMANY: Patients in Germany with bronchial asthma are highly likely to suffer from co-existing diseases and their treatments should reflect this.

    To report a study conducted to explore intensive care unit nurses' perceptions of patient participation in the acute phase of chronic obstructive pulmonary disease exacerbation. An acute exacerbation is a life-threatening situation, which patients often consider to be extremely frightening. Healthcare personnel exercise considerable power in this situation, which challenges general professional notions of patient participation. Critical discourse analysis. In the autumn of 2009, three focus group interviews with experienced intensive care nurses were conducted at two hospitals in western Norway. Two groups had six participants each, and one group had five (N = 17). The transcribed interviews were analysed by means of critical discourse analysis. The intensive care nurses said that an exacerbation is often an extreme situation in which healthcare personnel are exercising a high degree of control and power over patients. Patient participation during exacerbation often takes the form of non-involvement. The participating nurses attached great importance to taking a sensitive approach when meeting patients. The nurses experienced challenging ethical dilemmas. This study shows that patient participation should not be understood in universal terms, but rather in relation to a specific setting and the interactions that occur in this setting. Healthcare personnel must develop skill, understanding, and competence to meet these challenging ethical dilemmas. A collaborative inter-professional approach between physicians and nurses is needed to meet the patients' demand for involvement. © 2012 Blackwell Publishing Ltd.

En los países de nuestro entorno ocupa el cuarto lugar como causa de muerte y su incidencia va en aumento. Su exacerbación aguda puede deberse a muy diferentes motivos, y supone una consulta frecuente tanto en el ámbito de la atención primaria como hospitalaria. En el presente trabajo se revisa el tratamiento actual de la exacerbación aguda, en la que hay que considerar obligatorios, el oxígeno en concentración adecuada, los broncodilatadores, los corticoides y los antibióticos.In our country, chronic obstructive pulmonary disease is a highly prevalent entity as a result of the increase of smoking and of life expectancy. In our geographical area, it is the fourth cause of death and its incidence is growing. Its acute exacerbation may be caused by very different reasons, and it should be frequently consulted, both at the primary care and hospital level. In this paper, the current treatment of acute exacerbation is reviewed. A proper oxygen concentration, bronchodilators, corticoids, and antibiotics should be considered as compulsory for this condition.

    The objective of this study was to evaluate the preventive effects of oral administration of lansoprazole on acute exacerbation of chronic obstructive pulmonary disease (COPD). Patients with COPD in groups C and D in the stable phase were stratified into a group with neither gastroesophageal reflux nor lansoprazole therapy (group A) and a group subjected to oral lansoprazole therapy (group B1 ) and a group not subjected to oral lansoprazole therapy (group B2 ). The frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire, COPD assessment test (CAT) questionnaire, pulmonary function test and the 6-minute walk test were applied; in addition, arterial blood gas, white blood cell (WBC), hs-CRP, liver function and the levels of IL-1β, IL-6, IL-8, TNF-α and GM-CSF in sputum were monitored during follow-up. In the 12-month follow-up period, the frequency of exacerbation in group B2 was statistically higher than that in groups A and B1 (P lansoprazole therapy decreased the frequency of acute exacerbation of COPD by alleviating gastroesophageal reflux and lowering the levels of IL-1β, IL-6, IL-8, TNF-α and GM-CSF in the sputum. © 2016 The Authors.

    Acute cholangitis as a result of common bile duct stones can be managed; however, cholangitis caused by occlusion with a biliary self-expandable metallic stent (SEMS) in patients with an unresectable malignant biliary obstruction has not been fully discussed. The acute cholangitis clinical guidelines (Tokyo Guidelines 2013) recommend following the same procedure as that used for cholangitis; however, the patient's condition, including performance status, tumor extension or staging, and prognosis must be considered. Most physicians manage cholangitis from a SEMS occlusion using a two-step procedure. They insert endoscopic drainage with a plastic stent or insert a nasobiliary drainage tube, which does not exacerbate sepsis. Addition or replacement of a biliary SEMS is required in many cases depending on the cause of the occlusion. Tumor ingrowth through the stent mesh is common in uncovered SEMS and requires placement of another stent in an in-stent method. However, covered SEMS tends to be occluded by sludge, so it must be replaced because of the bacterial biofilm that forms on the covering membrane. The location of the biliary stricture (hilar or distal) should also be considered. Strategies for managing cholangitis as a result of occlusion by a biliary SEMS remain controversial, so prospective clinical trials are needed. © 2017 The Authors.

    Full Text Available Neurogenic pulmonary edema (NPE is an acute life-threatening complication associated with many forms of central nervous system injury. Its pathophysiology is still debated. We report a patient with acute obstructive hydrocephalus due to a central neurocytoma who also had NPE, for which serial transpulmonary thermodilution monitoring (PiCCO was performed. Insertion of the PiCCO, which provides information about the patient's cardiac output, preload status and amount of lung water, revealed a high pulmonary vascular permeability index (PVPI and low global end-diastolic volume (GEDV without cardiac dysfunction, indicating permeability edema, which led to our changing the therapeutic strategy. Using PiCCO monitoring to balance the preload and extent of pulmonary edema enabled achievement of an optimal cardiac preload for organ perfusion, resulting in normalization of pulmonary edema by day 2. PiCCO facilitates understanding of the mechanism of NPE, guiding the management of fluid balance and the choice of vasopressors in patients with life-threatening NPE.

    Full Text Available BACKGROUND Acute exacerbation of chronic obstructive pulmonary disease being an all too common cause for hospital admissions Worldwide poses a logistical stress for the treating physicians and hospital administration with regards to morbidity and mortality rates. Identifying upon admission those at higher risk of dying in-hospital could be useful for triaging patients to the appropriate level of care, determining the aggressiveness of therapies and timing safe discharges. The aim of this study was to evaluate the utilisation of the DECAF score in predicting in hospital outcome in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD in a Tertiary Care Hospital of Southern India. MATERIALS AND METHODS Patients admitted with COPD exacerbations in K.R. Hospital, Mysore Medical College And Research Institute, Mysuru in between the May 2017 and July 2017 were taken has study subjects. A total of 80 patients were taken into the study. The duration of hospital stay, ICU admission and deaths were noted. DECAF score is applied to all study subjects and the severity of AECOPD is graded at the time of admission. The data collected and complied were then analysed for the correlation between score and subsequent management and overall outcome. RESULTS Total of 80 patients were recruited in the study. Mean age for male was 66.47, female was 70.86. Length of hospital stay was more in patients with decaf score more than 3 (average hospital stay 10 days. Patients with DECAF score of 2, 70.4% required inhalations oxygen, remaining 29.6% were managed with only bronchodilators whereas patients with DECAF score of 5 (max score in our study group there was a 100% initiation of assisted ventilation 33.3% received NIV ventilation while 66.6% required endotracheal intubation with ventilator support. In present study, 85 percent patients were survived. Total 6 patients (7.5% had died, belonging to high risk DECAF group (score 3 to 6

    We present a derma-respiratory syndrome in a patient occupationally exposed to trichloroethylene (TCE). At the beginning of its industrial use trichloroethylene was considered harmless. But, in time it showed a high noxious capacity. It produces an important and various pathology, which evolves as acute or chronic disease. The case we present shows that trichloroethylene can induce cutaneous pathology that excels contact dermatitis. It also proves that trichloroethylene can produce systemic effects (obstructive respiratory syndrome). The particularity of the case is based on the succession of the events, first the cutaneous and then the respiratory effects. A long period of time was necessary for the installation of the symptoms (for cutaneous and bronchial sensitization to take place). The case presented is the proof that trichloroethylene's great toxicity cannot be doubted and that the clinical forms due to sensitization to trichloroethylene can be dramatic.

    Chronic obstructive pulmonary disease (COPD) is the cause of substantial economic and social burden. We evaluated the temporal trends of hospitalizations from acute exacerbation of COPD and determined its outcome and financial impact using the National (Nationwide) Inpatient Sample (NIS) databases (2002-2010). Individuals aged ≥ 18 years were included. Subjects who were hospitalized with primary diagnosis of COPD exacerbation and those who were admitted for other causes but had underlying acute exacerbation of COPD (secondary diagnosis) were captured by International Classification of Diseases-Ninth Revision (ICD-9) codes. The hospital outcomes and length of stay were determined. Multivariate logistic regression was used to identify the independent predictors of inpatient mortality. Overall acute exacerbation of COPD-related hospitalizations accounted for nearly 3.31% of all hospitalizations in the year 2002. This did not change significantly to year 2010 (3.43%, p = 0.608). However, there was an increase in hospitalization with secondary diagnosis of COPD. Elderly white patients accounted for most of the hospitalizations. Medicare was the primary payer source for most of the hospitalizations (73-75%). There was a significant decrease in inpatient mortality from 4.8% in 2002 to 3.9% in 2010 (slope -0.096, p < 0.001). Similarly, there was a significant decrease in average length of stay from 6.4 days in 2002 to 6.0 days in 2010 (slope -0.042, p < 0.001). Despite this, the hospitalization cost was increased substantially from $22,187 in 2002 to $38,455 in 2010. However, financial burden has increased over the years.

    To compare, through analysis of the coronary artery calcium (CAC) score and the risk factors for atherosclerosis, the characteristics of acute coronary syndrome between an asymptomatic high-risk group of atherosclerosis patients and a chronic coronary arterial obstructive disease(CAOD) group. The CAC scores of an asymptomatic high-risk group of atherosclerosis patients (group I, n=284), a chronic CAOD croup (group II, n=39) and an acute coronary syndrome group (group III, n=21) were measured by electron beam tomography. Forty-seven patients with CAOD from groups II and III underwent coronary angiography, and we scrutinized age, sex and risk factors including diabetes mellitus, hypertension, obesity, smoking, hypercholesterolemia and low high-density lipoproteinemia. The numbers of stenotic coronary arterial branches and degree of stenosis revealed by coronary angiography were also recorded. We determined the differences between the three groups in terms of CAC score and the risk factors, the relationship between CAC score and risk factors, and the characteristic features of each type of CAOD group. The mean CA score of group III (135.1) was not statistically different from that of group I (135.7) or group II (365.8). Among patients aged below 50, the mean CAC score of group III (127.4) was significantly higher than that of group I (6.2), (p=0.0006). The mean CAC score at the sixth decade was also significantly different between group I(81.5) and group II (266.9). The mean age of group III (54.2 years) was significantly lower than that of group I (58.1 years) (p=0.047) and of group II (60.1) (p=0.022). There was significant correlation between the number of stenotic coronary arterial branches and log(CAC +1) (p<.01). The square root of the CAC score and the maximal degree of stenosis was also well correlated (p<.01). There was no difference in the mean number of risk factors among the three groups, though the incidence of smoking in group III was significantly

    Patients hospitalized with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) engage in low levels of activity, putting them at risk for relapse and future readmissions. There is little direction for health care providers regarding the parameters for safe exercise during an AECOPD that is effective for increasing activity tolerance before discharge from hospital, especially for patients with associated comorbid conditions. To report the rationale for and methods of a study to develop evidence-informed care recommendations that guide health care providers in the assessment, prescription, monitoring and progression of exercise for patients hospitalized with AECOPD. The present study was a multicomponent knowledge translation project incorporating evidence from systematic reviews of exercise involving populations with chronic obstructive pulmonary disease and⁄or common comorbidities. A Delphi process was then used to obtain expert opinion from clinicians, academics and patients to identify the parameters of safe and effective exercise for patients with AECOPD. Clinical decision-making tool(s) for patients and practitioners supported by a detailed knowledge dissemination, implementation and evaluation framework. The present study addressed an important knowledge gap: the lack of availability of parameters to guide safe and effective exercise prescription for hospitalized patients with AECOPD, with or without comorbid conditions. In the absence of such parameters, health care professionals may adopt an 'activity as tolerated' approach, which may not improve physical activity levels in their patients. The present study synthesizes the best available evidence and expert opinion, and will generate decision-making tools for use by patients and their health care providers.

    Introduction: Acute pulmonary emergencies in patient with cystic fibrosis (CF) can be found in cases of pneumothorax as well as hemoptysis. If the bleeding cannot be stopped by conservative methods, an embolization of the bronchial arteries should be done. Materials and Method: 11 patients were embolized using a combination of PVA particles and microcoils. Results: From January 1996 to June 2001 17 bronchial arteries in 11 patients were embolized. 7 patients suffered from chronical hemoptysis, 4 patients had an acute hemoptysis. In 4 patients both sides were embolized, in 3 patients only one side. The remaining 4 patients needed a second intervention, embolizing the other side. The primary embolizated bronchial artery was still closed in all 4 patients. In 1 patient the selective catheterization of a bronchial artery was not successful, thus the embolization could not be carried out. 1 patient died 5 days after the intervention due to a fulminant pneumonia (Pseudomonas aeruginosa) without recurrent bleeding. In two patients atypical branches from intercostal arteries feeding the bronchial arteries were detected and successfully embolized. All patients profited from the therapy, as bleeding could be stopped or at least be reduced. 3 patients suffered from back pain during or after intervention. There were no severe complications like neurological deficiencies or necroses. (orig.) [de

    Background Chronic Obstructive Pulmonary Disease (COPD) affects about 329 million people worldwide, which is nearly 5% of the entire global population. In the context of Nepal, COPD accounts for 43% of the non-communicable disease burden and 2.56% of hospitalizations. Various pre-disposing factors like bacterial, viral, fungal, smoking, occupational exposures and genetic factors have been proposed to precipitate COPD and its exacerbation though, the definitive pre-disposing factors and factors related to acute exacerbation have not been determined in the context of Nepal. Objective To find out the pre-disposing factors and the related causative agents for COPD. Method A cross sectional study was conducted in a tertiary care hospital. Patients of all age group who were diagnosed as COPD and admitted in the hospital were included in this study. Patients were interviewed using structured questionnaire. The sociodemographic data including personal and medical history were recorded from those participants. In addition, sputum from those patients was sent for culture to investigate the possible responsible pathogens as well as its antibiotic sensitivity pattern. Result A total of 150 patients having Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) who have admitted from either emergency or out-patient department of the hospital were included in this study. Among the total number of patients, more than half of them were female (n=82). In addition, analysis of occupations shows that most of them were either farmer (36.0%) or housewife (30.7%). In total studied patients (n=150), most of them were using traditional firewood (83%) for cooking purpose and majority of patients (91%) were smokers. Most of the sputum samples show growth of gram-positive cocci (26.7%) and gram negative bacilli (27.5%). Considering the overall sensitivity pattern, the higher sensitivity was recorded for Co-trimoxazole and Ciprofloxacin while higher rate of resistance was noted

    Eleven patients, with advanced chronic obstructive lung disease (COLD), received an infusion of the calcium antagonist felodipine at a rate of 0.9 mg/h. Pulmonary and systemic vascular resistances (PVR and SVR) at rest were reduced by 18% and 33%, respectively. Cardiac output increased by 33%. The right venticular and left venticular ejection fractions (RVEF and LVEF), measured by equilibrium gated radionuclide ventriculography, Increased by 32% and 25%, respectively. During exercise both PVR and SVR fell by a mean of 30%. RVEF and LVEF both increased by about 14%. After three months of oral felopdipine treatment, a dose-related decrease in PVR was noted at rest (r=-0.83) compared with pretreatment values. There was an increase in RVEF which correlated to a reduction in PVR. Three patiens discontinued the trial due to side effects. It is concluded that the reduction of PVR induced by felodipine is accompanied by an improvement in right heart function as measured by ejection fraction measurements.

    The colostomy is often necessary in complicated divertcular disease. The laparoscopic colostomy is not widely used for the treatment of complicated diverticular disease. Its use in patients with high operative risk is still on debate. The aim of this case report was to present the benefits of laparoscopic colostomy in patients with high peri-and postoperative risk factors. We present a case of 76-year-old female admitted to emergency unit for left colonic obstruction. The patient had a past history of liver cirrhosis HCV-related with a severe malnutrition, hypertrophic cardiomyopathy, diverticular disease, hiatal ernia, previous appendectomy. Patient was classified according to their preoperative risk ASA 3 (classification of the American society of Anestesia-ASA score). Contrast-enhanced abdominal CT revealed a marked thickening in the sigmoid colon and a marked circumferential stenosis in the sigmoid colon in absence of neoplasm, and/or abscess. The laparoscopic procedure is proposed as first intention. The operation time was 50min, and the hospital stay was 4 days. Post operative complications grade I according to the Clavien Dindo Classification. Laparoscopic colostomy is safe and feasible procedure in experienced hands. It is associated with low morbidity and short stay in hospital and should be considered a good alternative to a laparotomy. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    In patients with bronchial tumors, we frequently consider endoscopic treatment as the first treatment of choice. All computed tomography (CT) must satisfy several conditions necessary to analyze images by Synapse Vincent. To select safer and more precise approaches for patients with bronchial tumors, we determined the indications and efficacy of virtual navigation intervention for the treatment of bronchial tumors. We examined the efficacy of virtual navigation bronchial intervention for the treatment of bronchial tumors located at a variety of sites in the tracheobronchial tree using a high-speed 3-dimensional (3D) image analysis system, Synapse Vincent. Constructed images can be utilized to decide on the simulation and interventional strategy as well as for navigation during interventional manipulation in two cases. Synapse Vincent was used to determine the optimal planning of virtual navigation bronchial intervention. Moreover, this system can detect tumor location and alsodepict surrounding tissues, quickly, accurately, and safely. The feasibility and safety of Synapse Vincent in performing useful preoperative simulation and navigation of surgical procedures can lead to safer, more precise, and less invasion for the patient, and makes it easy to construct an image, depending on the purpose, in 5-10 minutes using Synapse Vincent. Moreover, if the lesion is in the parenchyma or sub-bronchial lumen, it helps to perform simulation with virtual skeletal subtraction to estimate potential lesion movement. By using virtual navigation system for simulation, bronchial intervention was performed with no complications safely and precisely. Preoperative simulation using virtual navigation bronchial intervention reduces the surgeon's stress levels, particularly when highly skilled techniques are needed to operate on lesions. This task, including both preoperative simulation and intraoperative navigation, leads to greater safety and precision. These technological instruments

    Conduct a cost-effectiveness analysis of FreeO 2 technology versus manual oxygen-titration technology for patients with chronic obstructive pulmonary disease (COPD) hospitalised for acute exacerbations. Tertiary acute care hospital in Quebec, Canada. 47 patients with COPD hospitalised for acute exacerbations. An automated oxygen-titration and oxygen-weaning technology. The costs for hospitalisation and follow-up for 180 days were calculated using a microcosting approach and included the cost of FreeO 2 technology. Incremental cost-effectiveness ratios (ICERs) were calculated using bootstrap resampling with 5000 replications. The main effect variable was the percentage of time spent at the target oxygen saturation (SpO 2 ). The other two effect variables were the time spent in hyperoxia (target SpO 2 +5%) and in severe hypoxaemia (SpO 2 <85%). The resamplings were based on data from a randomised controlled trial with 47 patients with COPD hospitalised for acute exacerbations. FreeO 2 generated savings of 20.7% of the per-patient costs at 180 days (ie, -$C2959.71). This decrease is nevertheless not significant at the 95% threshold (P=0.13), but the effect variables all improved (P<0.001). The improvement in the time spent at the target SpO 2 was 56.3%. The ICERs indicate that FreeO 2 technology is more cost-effective than manual oxygen titration with a savings of -$C96.91 per percentage point of time spent at the target SpO 2 (95% CI -301.26 to 116.96). FreeO 2 technology could significantly enhance the efficiency of the health system by reducing per-patient costs at 180 days. A study with a larger patient sample needs to be carried out to confirm these preliminary results.

    Full Text Available Background. About one third of patients with TIMI 3 after reperfusion have evidence of microvascular obstruction (MO which represents an independent predictor of myocardial wall rupture. This explains all efforts made to prevent MO. Magnetic resonance imaging (MRI has proved to be particularly useful in detecting MO. The aim of this study was to evaluate with MRI if different fibrinolytic regimens in acute myocardial infarction display different effects on left ventricle (LV volumes and ejection fraction (EF, as well as on myocardial infarct size (MIsz and MO. Methods. Twenty male patients, mean age 58 years, affected by acute myocardial infarction, ten anterior and ten inferior, were treated with: full dose reteplase in ten, and half dose reteplase plus full dose abciximab (R+Abcx in the other ten patients. In the fourth day after hospital admission, MRI STIR T2 images were used to quantify MIsz, while 2dflash cineloops were used after the injection of gadolinium, to quantify LV volumes, EF and to detect MO. Results. LV EF was higher in R+Abcx 51±10 than in reteplase 41±8. MIsz was similar in both treatment groups: however a close relationship was present between MIsz and EF in the reteplase group indicating that the greater the MIsz the lower the EF. In R+Abcx this relationship was no longer present, suggesting a protective effect of the drug on microcirculation. In fact extensive MO was present in 25% of all cases, 80% of which in the reteplase group while only 20% in R+Abcx. Conclusion. R+Abcx prevents MO: compared to traditional fibrinolytic therapy it allows better LV function and most likely improved long term survival.

    Self-treatment of acute exacerbations of COPD with antibiotics and/or oral corticosteroids has emerged as a promising strategy to reduce hospitalization rates, mortality and health costs. However, for reasons little understood, the effect of self-treatment, particularly when not part of comprehensive self-management programs, remains unclear. Therefore, this study aims to get insight into the patients' perspective on self-treatment of acute exacerbations of COPD, focusing specifically on how patients decide for the right moment to start treatment with antibiotics and/or oral corticosteroids, what they consider important when making this decision and aspects which might interfere with successful implementation. We interviewed 19 patients with chronic obstructive pulmonary disease using qualitative semi-structured interviews, and applied thematic analysis for data analysis. Patients were well equipped with experiential knowledge to recognize and promptly respond to worsening COPD symptoms. Worries regarding potential adverse effects of antibiotics and oral corticosteroids played an important role in the decision to start treatment and could result in hesitation to start treatment. Although self-treatment represented a practical and appreciated option for some patients with predictable symptom patterns and treatment effect, all patients favoured assistance from a medical professional when their perceived competence reached its limits. However, a feeling of obligation to succeed with self-treatment or distrust in their doctors or the health care system could keep patients from timely help seeking. COPD patients regard self-treatment of exacerbations with antibiotics and/or oral corticosteroids as a valuable alternative. How they engage in self-treatment depends on their concerns regarding the medications' adverse effects as well as on their understanding of and preferences for self-treatment as a means of health care. Caregivers should address these perspectives in a

    Full Text Available Chronic inflammatory airway diseases, such as bronchial asthma and chronic obstructive pulmonary disease, are common respiratory disorders worldwide. Exacerbations of these diseases are frequent and worsen patients' respiratory condition and overall health. However, the mechanisms of exacerbation have not been fully elucidated. Recently, it was reported that interleukin (IL-17A might play an important role in neutrophilic inflammation, which is characteristic of such exacerbations, through increased production of neutrophil chemoattractants. Therefore, we hypothesized that IL-17A was involved in the pathogenesis of acute exacerbation, due to viral infection in chronic inflammatory airway diseases. In this study, we assessed chemokine production by bronchial epithelial cells and investigated the underlying mechanisms. Comprehensive chemokine analysis showed that, compared with poly(I:C alone, co-stimulation of BEAS-2B cells with IL-17A and poly(I:C strongly induced production of such neutrophil chemoattractants as CXC chemokine ligand (CXCL8, growth-related oncogene (GRO, and CXCL1. Co-stimulation synergistically induced CXCL8 and CXCL1 mRNA and protein production by BEAS-2B cells and normal human bronchial epithelial cells. Poly(I:C induced chemokine expression by BEAS-2B cells mainly via Toll-like receptor 3/TIR-domain-containing adapter-inducing interferon-β-mediated signals. The co-stimulation with IL-17A and poly(I:C markedly activated the p38 and extracellular-signal-regulated kinase 1/2 pathway, compared with poly(I:C, although there was little change in nuclear factor-κB translocation into the nucleus or the transcriptional activities of nuclear factor-κB and activator protein 1. IL-17A promoted stabilization of CXCL8 mRNA in BEAS-2B cells treated with poly(I:C. In conclusion, IL-17A appears to be involved in the pathogenesis of chronic inflammatory airway disease exacerbation, due to viral infection by promoting release of neutrophil

    Acute exacerbations of chronic obstructive pulmonary disease (AE-COPD) are leading causes of mortality in hospital intensive care units. We sought to determine whether dental plaque biofilms might harbor pathogenic bacteria that can eventually cause lung infections in patients with severe AE-COPD. Paired samples of subgingival plaque biofilm and tracheal aspirate were collected from 53 patients with severe AE-COPD. Total bacterial DNA was extracted from each sample individually for polymerase chain reaction amplification and/or generation of bacterial 16S rDNA sequences and cDNA libraries. We used a metagenomic approach, based on bacterial 16S rDNA sequences, to compare the distribution of species present in dental plaque and lung. Analysis of 1060 sequences (20 clones per patient) revealed a wide range of aerobic, anaerobic, pathogenic, opportunistic, novel and uncultivable bacterial species. Species indistinguishable between the paired subgingival plaque and tracheal aspirate samples (97-100% similarity in 16S rDNA sequence) were dental plaque pathogens (Aggregatibacter actinomycetemcomitans, Capnocytophaga sputigena, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola) and lung pathogens (Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa and Streptococcus pneumoniae). Real-time polymerase chain reaction of 16S rDNA indicated lower levels of Pseudomonas aeruginosa and Porphyromonas gingivalis colonizing the dental plaques compared with the paired tracheal aspirate samples. These results support the hypothesis that dental bacteria may contribute to the pathology of severe AE-COPD. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Several cardiovascular magnetic resonance imaging (CMR) techniques are used to detect microvascular obstruction (MVO) after acute myocardial infarction (AMI). To determine the prevalence of MVO and gain more insight into the dynamic changes in appearance of MVO, we studied 84 consecutive patients with a reperfused AMI on average 5 and 104 days after admission, using an optimised single breath-hold 3D inversion recovery gradient echo pulse sequence (IR-GRE) protocol. Early MVO (2 min post-contrast) was detected in 53 patients (63%) and late MVO (10 min post-contrast) in 45 patients (54%; p = 0.008). The extent of MVO decreased from early to late imaging (4.3 {+-} 3.2% vs. 1.8 {+-} 1.8%, p < 0.001) and showed a heterogeneous pattern. At baseline, patients without MVO (early and late) had a higher left ventricular ejection fraction (LVEF) than patients with persistent late MVO (56 {+-} 7% vs. 48 {+-} 7%, p < 0.001) and LVEF was intermediate in patients with early MVO but late MVO disappearance (54 {+-} 6%). During follow-up, LVEF improved in all three subgroups but remained intermediate in patients with late MVO disappearance. This optimised single breath-hold 3D IR-GRE technique for imaging MVO early and late after contrast administration is fast, accurate and allows detection of patients with intermediate remodelling at follow-up.

    Full Text Available  Objective  To probe the value of endoscopic retrograde cholangiography (ERC through jejunostomy in patients in whom ERC could not be performed via the mouth after Roux-en-Y anastomosis on the upper gastrointestinal tract. Methods  In two patients suffering from acute obstructive suppurative cholangitis after a radical operation for cholangiocarcinoma, ERC could not be performed through the mouth due to the presence of a long non-functional jejunal loop. A jejunostomy was first done in the afferent loop of the jejunum, and a gastroscope was then inserted via the jejunostomy and passed retrogradely, to find the stoma of the cholangiointestinal anastomosis. ERC was then successfully performed, and followed by endoscopic retrograde biliary drainage (ERBD. Results  The operation was successful. It was found that cholangio-jejunostomy stoma was narrow, and a large amount of purulent mucus was present in the enlarged intrahepatic duct. ERC was done to enlarge the stoma, and a stent was placed into the main branch of the intrahepatic duct. Two patients achieved surgical success and smooth recovery after the operation. Conclusion  ERC through a jejunostomy in the patients who had Roux-en-Y cholangiojejunostomy following radical resection for cholangiocarcinoma, is a safe and effective surgical procedure.

    Full Text Available We aimed to investigate the efficacy of four severity-of-disease scoring systems in predicting the 28-day survival rate among patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD requiring emergency care. Clinical data of patients with AECOPD who required emergency care were recorded over 2 years. APACHE II, SAPS II, SOFA, and MEDS scores were calculated from severity-of-disease indicators recorded at admission and compared between patients who died within 28 days of admission (death group; 46 patients and those who did not (survival group; 336 patients. Compared to the survival group, the death group had a significantly higher GCS score, frequency of comorbidities including hypertension and heart failure, and age (P<0.05 for all. With all four systems, scores of age, gender, renal inadequacy, hypertension, coronary heart disease, heart failure, arrhythmia, anemia, fracture leading to bedridden status, tumor, and the GCS were significantly higher in the death group than the survival group. The prediction efficacy of the APACHE II and SAPS II scores was 88.4%. The survival rates did not differ significantly between APACHE II and SAPS II (P=1.519. Our results may guide triage for early identification of critically ill patients with AECOPD in the emergency department.

    Arterial hypertension is an established risk factor for acute coronary syndrome (ACS). Multidetector computed tomography (MDCT) is an accurate and less invasive technique for assessment of the degree of coronary artery luminal narrowing and characterization of coronary atherosclerosis. We therefore aimed to investigate the predictive power of MDCT for future ACS events and compared with traditional parameters in patients with hypertension. One hundred and thirty-four patients (93 men, mean age 70±11 years) with hypertension underwent MDCT for evaluation of coronary artery disease. MDCT analysis focused on the presence of plaques, the degree of stenosis, and the plaque characteristics. Traditional parameters included Framingham risk score, carotid intima-media thickness, and left ventricular mass index. During a mean follow-up of 39±10 months, ACS events occurred in 10 patients, including myocardial infarction (n=3) and unstable angina (n=7). Multivariate analysis identified total number of low attenuation plaques as an independent predictor of ACS events (p<0.001). We demonstrated that non-obstructive low attenuation coronary plaques on MDCT predicted more accurately future ACS events in patients with hypertension than traditional parameters. (author)

    Bronchial artery embolization has been effective in the treatment of massive hemoptysis. The purpose of this study was to report the effectiveness of bronchial artery embolization in patients with chronic recurrent hemoptysis intractable to medical treatment. This study included 25 patients who were admitted for treatment of chronic recurrent hemoptysis with bronchial artery embolization. Chronic recurrent hemoptysis was defined as condition in tractable to medical treatment persistently and occurring over two times per two months The target vessels for embolization were selected in consideration of the results of aortography as well as the finding of chest radiography and bronchoscopy. After selective arteriography for embolization by using 5-French Simmons catheter, embolic agents(mainly polyvinyl alcohol(PVA) and additionally gelfoam and coils) were released through the catheter. The results of the embolization were assessed with review of medical records. The cases of the hemoptysis were pulmonary tuberculosis(n=12.48%), bronchiectasis(n=6.24%), aspergilloma(n=3.12%), chronic obstructive pulmonary disease(n=2.8%), chronic bronchitis(n=1.4%) and lung abscess(n=1.4%). Selective embolization was carried out in 49 sites(42 in bronchial artery and 7 in nonbronchial systemic collaterals). Early success rate within 2 months was 96%. After long-term follow up study (6-30 months, average 15 months), complete remission was 72%, partial remission 12% and recurrence 12% respectively. During and after embolization, major complications such as spinal cord injury or bronchial wall necrosis was not found. Minor complications were chest pain, shoulder pain and chilling sense, which were relieved spontaneously within a few days. High success rate and relatively low recurrence with no significant complication were achieved with bronchial artery embolization in the patients complaining of chronic recurrent hemoptysis.

    Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

    Bronchial asthma is a clinical syndrome characterized by the reversibility of airway obstruction. Recently it has been suggested that remodeling of the airway causes irreversible airway obstruction which may be responsible for the patient's symptoms. With this background, the purpose of the present study was to assess patients with corticosteroid-dependent asthma by Tc-99m Technegas scintigraphy (Technegas) in both planar and SPECT images. Twelve patients (7 females and 5 males aged 36-72 years with a median age of 60 years: 4 smokers and 8 non-smokers) with oral corticosteroid-dependent asthma were enrolled in this study. Lung ventilation scanning with Technegas in both planar and SPECT images, high-resolution computed tomography, and pulmonary function tests were performed in all patients. The results of Technegas scanning were graded and correlations with other clinical parameters were evaluated. Significant abnormalities were detected by ventilation scintigraphy with Technegas in patients with corticosteroid-dependent bronchial asthma even during remission. Our data demonstrate that airflow obstruction took place in patients with corticosteroid-dependent asthma even during remission. Technegas scanning appears to be a useful radiopharmaceutical for demonstrating airflow obstruction in patients with bronchial asthma. (author)

    2009-08-01

    Full Text Available Abstract Background The presence and extent of microvascular obstruction (MO after acute myocardial infarction can be measured by first-pass gadolinium-enhanced perfusion cardiovascular magnetic resonance (CMR or after gadolinium injection with early or late enhancement (EGE/LGE imaging. The volume of MO measured by these three methods may differ because contrast agent diffusion into the MO reduces its apparent extent over time. Theoretically, first-pass perfusion CMR should be the most accurate method to measure MO, but this technique has been limited by lower spatial resolution than EGE and LGE as well as incomplete cardiac coverage. These limitations of perfusion CMR can be overcome using spatio-temporal undersampling methods. The purpose of this study was to compare the extent of MO by high resolution first-pass k-t SENSE accelerated perfusion, EGE and LGE. Methods 34 patients with acute ST elevation myocardial infarction, treated successfully with primary percutaneous coronary intervention (PPCI, underwent CMR within 72 hours of admission. k-t SENSE accelerated first-pass perfusion MR (7 fold acceleration, spatial resolution 1.5 mm × 1.5 mm × 10 mm, 8 slices acquired over 2 RR intervals, 0.1 mmol/kg Gd-DTPA, EGE (1–4 minutes after injection with a fixed TI of 440 ms and LGE images (10–12 minutes after injection, TI determined by a Look-Locker scout were acquired. MO volume was determined for each technique by manual planimetry and summation of discs methodology. Results k-t SENSE first-pass perfusion detected more cases of MO than EGE and LGE (22 vs. 20 vs. 14, respectively. The extent of MO imaged by first-pass perfusion (median mass 4.7 g, IQR 6.7 was greater than by EGE (median mass 2.3 g, IQR 7.1, p = 0.002 and LGE (median mass 0.2 g, IQR 2.4, p = 0.0003. The correlation coefficient between MO mass measured by first-pass perfusion and EGE was 0.91 (p Conclusion The extent of MO following acute myocardial infarction appears larger on

For some, AHRF is terminal and NIV is inappropriate. However there is no definitive method of identifying patients who are unlikely to survive. The aim of this study was to identify factors associated with inpatient mortality from AHRF with respiratory acidosis due to COPD.Methods: COPD patients presenting with AHRF and who were treated with NIV were studied prospectively. The forced expiratory volume in 1 second (FEV1, World Health Organization performance status (WHO-PS, clinical observations, a composite physiological score (Early Warning Score, routine hematology and biochemistry, and arterial blood gases prior to commencing NIV, were recorded.Results: In total, 65 patients were included for study, 29 males and 36 females, with a mean age of 71 ± 10.5 years. Inpatient mortality in the group was 33.8%. Mortality at 30 days and 12 months after admission were 38.5% and 58.5%, respectively. On univariate analysis, the variables associated with inpatient death were: WHO-PS ≥ 3, long-term oxygen therapy, anemia, diastolic blood pressure < 70 mmHg, Early Warning Score ≥ 3, severe acidosis (pH < 7.20, and serum albumin < 35 g/L. On multivariate analysis, only anemia and WHO-PS ≥ 3 were significant. The presence of both predicted 68% of inpatient deaths, with a specificity of 98%.Conclusion: WHO-PS ≥ 3 and anemia are prognostic factors in AHRF with respiratory acidosis due to COPD. A combination of the two provides a simple method of identifying patients unlikely to benefit from NIV.Keywords: acute exacerbations of COPD, noninvasive ventilation, emphysema, prognostic markers

    Highlights: • The percentage infarct size (%IS) was significantly greater in the microvascular obstruction (MO) group than in the non-MO group. • The percentage mismatch score (%MMS) on dual scintigraphy significantly correlated with the %IS and the percentage MO. • The %MMS was significantly greater in the non-MO group than in the MO group, and was an independent predictor for MO. - Abstract: Background: The hypo-enhanced regions within the hyper-enhanced infarct areas detected by cardiac magnetic resonance (CMR) imaging reflect microvascular obstruction (MO) after acute myocardial infarction (AMI). The combined myocardial thallium-201 ({sup 201}Tl)/iodine-123-15-(p-iodophenyl)-3-(R,S)-methylpentadecanoic acid ({sup 123}I-BMIPP) dual single-photon emission computed tomography (SPECT) is a useful tool for detecting myocardial reversibility after AMI. We evaluated whether MO could be an early predictor of irreversible myocardial damage in comparison with {sup 201}Tl and {sup 123}I-BMIPP dual SPECT findings in AMI patients. Methods: Sixty-two patients with initial AMI who successfully underwent coronary revascularization were enrolled. MO was defined by CMR imaging. Patients were divided into 2 groups as follows: MO group (n = 32) and non-MO group (n = 30). Scintigraphic defect scores were calculated using a 17-segment model with a 5-point scoring system. The mismatch score (MMS) was calculated as follows: the total sum of (Σ) {sup 123}I-BMIPP defect score minus Σ{sup 201}Tl defect score. The percentage mismatch score (%MMS) was calculated as follows: MMS/(Σ{sup 123}I-BMIPP score) × 100 (%). Results: The percentage infarct size (%IS) was significantly greater in the MO group than in the non-MO group (32.2 ± 13.8% vs. 18.3 ± 12.1%, p < 0.001). The %MMS significantly correlated with the %IS and the percentage MO (r = −0.26, p = 0.03; r = −0.45, p < 0.001, respectively). The %MMS was significantly greater in the non-MO group than in the MO group (45.4

    Objective: To explore the role of endothelin and related cytokines (IL-5, IL-6, IL-8) in the development of bronchial asthma in pediatric patients. Methods: Plasma ET-1 (with RIA) and serum IL-5 (with ELISA), IL-6, IL-8 (with RIA) levels were measured in 42 pediatric patients with bronchial asthma and 30 controls. Results: The plasma ET-1 levels in the patients during acute attack (n=22) were significantly higher than those in patients during remission (n=20) as well as in controls (P 0.05). Levels of ET-1 were positively correlated with those of IL-5 (during attack, r=0.560, P<0.01; during remission, r=0.435, P<0.01). Conclusion: ET and the cytokines IL-5, IL-6, IL-8 participated in the pathogenesis of bronchial asthma through different mechanisms and dynamic determination of which could reflect the progression of the disease.

    Full Text Available Abstract Background Solitary endobronchial papillomas (SEP are rare tumors and most of them are described by case report. A misdiagnosis is common with viral related papillomas. A histopathological classification has recently permitted a major advancement in the understanding of the disease. Case Presentation We report a case of a mixed bronchial papilloma with an unusual endoscopic presentation. The literature was extensively reviewed to ascertain the unusual characteristics of the current case. A 39-year of age male was referred to our institution for the investigation of a slight hemoptysis. Routine examination was normal. A fibroscopy revealed an unusual feature of the right main bronchus. The lesion was a plane, non-bleeding, non-glistering sub-mucosal proliferation. No enhanced coloration was noticed. Biopsies revealed a mixed solitary bronchial papilloma. In situ HPV hybridization was negative. Endoscopic treatment (electrocautery was effective with no relapse. Conclusion This lesion contrasts with the data of the literature where papilloma were described as wart-like lesions or cauliflower tumors, with symptoms generally related to bronchial obstruction. We advise chest physicians to be cautious with unusually small swollen lesions of the bronchi that may reveal a solitary bronchial papilloma. Endoscopic imaging can significantly contribute to the difficult diagnosis of SEP by pulmonary physicians and endoscopists.

    Tobacco smoking in any form is a major risk factor for coronary artery disease (CAD), hypertension (HTN), chronic obstructive pulmonary disease (COPD), oral, nasopharyngeal, bronchial and other visceral malignancies. Cessation of smoking exerts considerable beneficial effect on development, recurrence and prognosis of these diseases. Present communication is based on the study of nine cases who had concurrent CAD, HTN, COPD and mitotic and/or pre malignant lesions due to unabated smoking. The youngest patient was a 35-year-old male having a smoking index of 300, presenting with acute coronary syndrome, COPD, HTN and buccal leukoplakia. Associated genitourinary malignancies in two cases and osteosarcoma in one case was an unusual presentation. These cases highlight the prognosis and public health implications of continuous smoking.

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

    Endobronchial tuberculosis and bronchogenic cancer are common causes of atelectasis or obstructive pneumonitis in Korea. Differentiation between endobronchial tuberculosis and bronchogenic carcinoma is important for the treatment and prognosis but it is sometimes difficult to differentiate these two lesions with radiologic examinations. The purpose of this study was to find the differential points between endobronchial tuberculosis and bronchogenic carcinoma associated with atelectasis or obstructive pneumonitis. Forty patients in whom atelectasis or obstructive pneumonitis was detected on chest radiographs comprised the study. A definite mass opacity was not observed on chest radiographs in all patients. In these patients, the causes of obstruction were endobronchial tuberculosis (n = 20) and bronchogenic cancer (n = 20) which were microbiologically or pathologically confirmed. Double obstructive lesions were more frequently found in endobronchial tuberculosis (8/20) than in bronchogenic cancer (1/20). Multiple calcification along the bronchial wall and severe distortion of bronchi were observed only in endobronchial tuberculosis (4/20) and associated low density mass at obstruction site was only observed in bronchogenic cancer (6/20). Bronchial dilatation (11/20) and parenchymal calcifications (14/20) distal to obstruction site, air containing bronchogram at post obstructive bronchus (14/20) were more frequently found in endobronchial tuberculosis. Contour bulging at obstruction site (14/20), and only mucus bronchogram at post obstructive bronchus (14/20) were more frequently found in bronchogenic carcinoma. In patients with atelectasis or obstructive pneumonitis, endobronchial tuberculosis is characterized by double obstructive lesion, multiple calcifications at the bronchial wall, and severe distortion of the bronchi. Endobronchial carcinoma is characterized by a low density mass at the obstructive site

    To evaluate the relationship between alcohol consumption and the risk of acute exacerbation of COPD (AECOPD). We conducted a secondary analysis of data previously collected in a large, multicenter trial of daily azithromycin in COPD. To analyze the relationship between amount of baseline self-reported alcohol consumption in the past 12 months and subsequent AECOPD, we categorized the subjects as minimal (alcohol users (>60 drinks/month). The primary outcome was time to first AECOPD and the secondary outcome was AECOPD rate during the 1-year study period. Of the 1,142 enrolled participants, 1,082 completed baseline alcohol questionnaires and were included in this analysis. Six hundred and forty-five participants reported minimal alcohol intake, 363 reported light-to-moderate intake, and 74 reported heavy intake. There were no statistically significant differences in median time to first AECOPD among minimal (195 days), light-to-moderate (241 days), and heavy drinkers (288 days) (P=0.11). The mean crude rate of AECOPD did not significantly differ between minimal (1.62 events per year) and light-to-moderate (1.44 events per year) (P=0.095), or heavy drinkers (1.68 events per year) (P=0.796). There were no significant differences in hazard ratios for AECOPD after adjustment for multiple covariates. Among persons with COPD at high risk of exacerbation, we found no significant relationship between self-reported baseline alcohol intake and subsequent exacerbations. The number of patients reporting heavy alcohol intake was small and further study is needed to determine the effect of heavy alcohol intake on AECOPD risk.

  9. Recent developments regarding periostin in bronchial asthma

    Full Text Available Although it is currently recognized that bronchial asthma is not a single disease but a syndrome, we have not yet made use of our new understanding of this heterogeneity as we treat asthma patients. To increase the efficacy of anti-asthma drugs and to decrease costs, it is important to stratify asthma patients into subgroups and to develop therapeutic strategies for each subgroup. Periostin has recently emerged as a biomarker for bronchial asthma, unique in that it is useful not in diagnosis but in categorizing asthma patients. We first found that periostin is a novel component of subepithelial fibrosis in bronchial asthma downstream of IL-13 signals. Thereafter, it was shown that periostin can be a surrogate biomarker of type 2 immune responses, the basis of the notion that a detection system of serum periostin is potentially a companion diagnostic for type 2 antagonists. Furthermore, we have recently shown that serum periostin can predict resistance or hyporesponsiveness to inhaled corticosteroids, based on its contribution to tissue remodeling or fibrosis in bronchial asthma. Thus, serum periostin has two characteristics as a biomarker for bronchial asthma: it is both a surrogate biomarker of type 2 immune responses and a biomarker reflecting tissue remodeling or fibrosis. We can take advantage of these characteristics to develop stratified medicine in bronchial asthma.

    The pulmonary complications of sickle cell disease (SCD) are a leading cause of morbidity and mortality (MacLean et al. Am J Respir Crit Care Med 178:1055-1059, 2008; Klings et al. Am J Respir Crit Care Med 173:1264-1269, 2006; National Heart, Lung, and Blood Institute, 2009). Despite this recognition, predictive markers of lung dysfunction progression remain elusive (Klings et al. Am J Respir Crit Care Med 173:1264-1269, 2006; Platt et al. N Engl J Med 330:1639-1644, 1994; Caboot et al. Curr Opin Pediatr 20:279-287, 2008; Field et al. Am J Hematol 83:574-576, 2008; Shirlo et al. Peadiatr Respir Review 12:78-82, 2011). This study was designed describe the longitudinal progression and identify specific markers that influence bronchial disease in SCD. A retrospective, chart review of 89 patients with SCD was conducted. All patients underwent spirometry in conjunction with body plethysmography as part of routine care. Eleven lung function variables were assessed, five of which were selected to establish patterns of normal, obstructive, restrictive, or mixed obstructive-restrictive physiology (Klings et al. Am J Respir Crit Care Med 173:1264-1269, 2006; Field et al. Am J Hematol 83:574-576, 2008). In the unadjusted model, forced expiratory volume in one second (FEV1)% of predicted trended downward with age, while total lung capacity (TLC)% of predicted showed a bimodal distribution and carbon monoxide diffusion capacity corrected for hemoglobin (DLCOcor)% of predicted remained stable. Adjusting for acute chest syndrome (ACS) episodes, medication status, and growth velocity (GV), the final model demonstrated that the downward trend between FEV1% of predicted with age was further influenced by the latter two factors. Initial decline in FEV1% of predicted is associated with worsening pulmonary dysfunction over time. Independent of ACS episodes, the factors most influential on the progression of FEV1% predicted include the introduction of medications as well as the

    Bronchial atresia is a rare congenital abnormality that usually shows a juxta-hilar mass with distal radiolucency on conventional x-ray films. Most patients are young and have no symptoms. Computed tomography usually confirms the diagnosis, allowing conservative management of the asymptomatic cases. The authors report three cases of bronchial obstruction. One of the patients was of particular importance and interest, a 45-year-old female patient with symptoms of respiratory infection, due to the association with a bulky bronchocele. The diagnosis was made by analyzing the findings of conventional x-ray films and computed tomography, and the comparison with previous conventional x-ray films and linear tomography, which had already demonstrated abnormalities. A literature review on the clinical and radiological findings of this pulmonary malformation is presented. (author)

    Hedgehog Interacting Protein (HHIP) was implicated in chronic obstructive pulmonary disease (COPD) by genome-wide association studies (GWAS). However, it remains unclear how HHIP contributes to COPD pathogenesis. To identify genes regulated by HHIP, we performed gene expression microarray analysis in a human bronchial epithelial cell line (Beas-2B) stably infected with HHIP shRNAs. HHIP silencing led to differential expression of 296 genes; enrichment for variants nominally associated with COPD was found. Eighteen of the differentially expressed genes were validated by real-time PCR in Beas-2B cells. Seven of 11 validated genes tested in human COPD and control lung tissues demonstrated significant gene expression differences. Functional annotation indicated enrichment for extracellular matrix and cell growth genes. Network modeling demonstrated that the extracellular matrix and cell proliferation genes influenced by HHIP tended to be interconnected. Thus, we identified potential HHIP targets in human bronchial epithelial cells that may contribute to COPD pathogenesis. PMID:23459001

    Fifty-four opium smokers with chronic obstructive lung disease were studied for two-and-a-half years. Forty-eight patients had a cough for at least two years before the onset of inappropriate exertional dyspnoea. Fine, bubbling adventitious sounds suggesting small airway disease were heard on auscultation over the middle and lower lobes in 38 patients. The prevalence of inflammatory lung disease and chronic respiratory failure in this series is suggested as the main cause for the frequent finding of right ventricular hypertrophy and congestive heart failure. Physiological studies revealed moderate to severe airways obstruction with gross over-inflation and, in 32 patients, an additional restrictive defect probably due to peribronchiolar fibrosis. Radiological evidence of chronic bronchitis and bronchiolitis was observed in 45 patients, `pure' chronic bronchiolitis in six patients, and `widespread' emphysema in 25 patients respectively. Necropsy examinations in nine patients, however, showed destructive emphysema of variable severity in all. Chronic bronchiolitis often associated with striking bronchiolectasis was present in six cases. More severe bronchiolar rather than bronchial inflammation was noted. The heavy opium smokers had characteristic nodular shadows on chest radiography, sometimes associated with a striking reticular pattern not seen in `pure' cigarette smokers. This was due to gross pigmented dust (presumably carbon) deposition in relation to blood vessels, lymphatics, and bronchioles, and also within the alveoli. It is speculated that the initial lesion is an acquired bronchiolitis. Opium smoking induces an irritative bronchopathy favouring repeated attacks of acute bronchiolitis and eventually resulting in obliterative bronchiolitis, peribronchiolar fibrosis, chronic bronchitis, and destructive emphysema.

    Full Text Available Background: There are many reports on the association between anthracosis and tuberculosis. This study focuses on bronchial anthracosis and associated diseases in the province of South Khorasan-Iran. Methods: This case-series study is performed on patients referred to the Vali-e-Asre Hospital (South Khorasan-Iran for bronchoscopic evaluations during the period of 2009-2012. Written informed consents were obtained prior to bronchoscopic evaluations. The criterion for diagnosis of bronchial anthracosis was black pigmentation on direct observation of bronchus. Bronchial anthracosis was classified into simple (without deformity or complicated (with deformity. Pulmonary tuberculosis (TB was diagnosed either by acid fast staining and culture of liquid samples, or histopathology examination of biopsy. Spirometry was performed to determine the obstructive or restrictive pattern. Results: Among 279 patients who underwent bronchoscopic evaluations, 89 patients, including 34 males (38.2% and 55 (61.79% females, were diagnosed with anthracosis. Simple and complicated anthracosis were observed in 42 (48.2% and 47 (52.8% cases respectively. Mean age of patients was 72.23±9.65 years. There were 43 (48.3% cases of tuberculosis (28 cases with complicated and 15 cases with simple anthracosis (P=0.021. Chest X-ray showed consolidation/infiltration, reticular/fibrotic, and mass/nodule/hilar prominence in 57 (64%, 26 (29.21% and 6 (6.74% cases, respectively. Bronchitis was reported in 42 (%59.15 out of 79 patients whose biopsy samples were taken. Spirometric patterns were obstructive, restrictive, upper airway obstruction, and normal in 45 (50.56%, 32 (35.95%, 2 (2.24%, and 10 (11.23% patients respectively. Conclusion: Tuberculosis is the most frequent disease associated with anthracosis in South Khorasan province. Consequently, patients with anthracosis must be carefully evaluated for tuberculosis.

    Bronchial thermoplasty (BT) is an emerging treatment modality for patients with difficult to treat asthma. It has been shown to be beneficial for symptom control and improves quality of life and reduces frequency of hospitalization. Safety data from the two major trials of BT indicate that patients who undergo these procedures are most likely to experience adverse respiratory events in the first six weeks post treatment. Lung abscess has never been reported as a direct complication of BT. In this case; we report a lung abscess as an immediate complication of BT, which we believe may be the first case. We describe a forty three year old Caucasian female presented three days post-bronchial thermoplasty with left sided chest pain radiating to the back associated with shortness of breath, wheeze and dry cough. She had also started to feel hot and cold and generally unwell. It remains unclear why this patient developed a lung abscess so acutely post BT treatment. It is important that safety data continues to be collated and published as the procedure becomes more widely available with further long term follow-up in particular.

  18. Successful Treatment of Bronchoesophageal Fistula With Esophageal and Bronchial Stenting

    2011-04-01

    Full Text Available Bronchoesophageal fistula is reported in 5-10% of patients with esophageal cancer. In most of these cases, the insertion of a single stent, either a tracheobronchial or an esophageal stent, is sufficient to seal off the fistula. In this case we describe a 67-year-old man with esophageal cancer and complications of bronchoesophageal fistula, which resulted in repeated pneumonia and acute respiratory failure. Initially, two expandable metallic membranous esophageal stents were placed to cover the fistula. However, the esophageal stent failed to stop the air leak and dislodged into the stomach. Thereafter, a bronchial stent was placed at the right intermediate bronchus and successfully stopped the air leak. The patient was then weaned from the ventilator 1 week after the insertion of a bronchial stent. In conclusion, stenting in both the esophagus and airways should be considered when both are severely invaded by malignancy, when the airway is compressed, or when the fistula is insufficiently sealed by an esophageal stent.

    1999-01-01

    Objective: To evaluate the radiological findings of bronchial mucoid impaction in 28 patients in order to improve diagnostic efficacy. Methods: Standard posteroanterior high voltage radiographs were performed in all 28 cases. Among them CT scans were taken in 14 cases, while 3 patients underwent HRCT examination at the same time. Twenty-two patients had a history of expectoration of mucous plugs; in one case with pulmonary atelectasis, a mucous plug was picked out through bronchoscopy. The other 5 cases experienced a lung operation, and a tumor and bronchial mucoid impaction were discovered. Results: Radiographs showed most mucoid impaction as thick, branching structures resembling branches of tree; others were in the shapes of spherical, small clubs, and cuttle fish. In one patient, pulmonary atelectasis was the only radiographic finding. Similarly on CT, most bronchial mucoid impaction were likened to tree branches; the rest presented as small clubs and bunches of grape. A prominent feature of bronchial mucoid impaction, either on plain radiograph or on CT, was that its axis pointed to the hilum, completely consistent with the branching and distribution of the bronchi, and accompanied by bronchiectasis. Conclusions: It is an optimal approach to exploit plain radiograph combined with CT to find out bronchial mucoid impaction. An awareness of its clinical and radiological features may improve better understanding and recognition of the disease

    Full Text Available Traumatic intramural hematoma of the duodenum is a rare cause of acquired duodenal obstruction in children, and a high degree of suspicion is therefore required to make an early and accurate diagnosis. We report a 6-year-old boy whose epigastrium was impacted by the handlebar of his bicycle during a traffic accident. The boy then experienced epigastralgia. Six days later, progressive bilious vomiting suggestive of gastrointestinal obstruction was noted. Imaging studies revealed a large hematoma extending from the fourth portion of the duodenum to the jejunum. Conservative methods of treatment failed to manage his condition. He underwent laparoscopic surgery to evacuate the hematoma. We also report a case of duodenal obstruction in a previously healthy 2-year-old girl who presented for the first time with acute symptoms of proximal intestinal obstruction. Contrast examinations showed apparent barium retention over the stomach and proximal duodenum. She underwent surgery due to persistent obstruction, and a mushroom-like foreign body was detected embedded in the orifice of the windsock duodenal web. After duodenoduodenostomy and removal of the bezoar, she had a smooth recovery and tolerated feeding well. We conclude that blunt abdominal trauma and incomplete duodenal obstruction, such as that caused by duodenal web, should be considered as possible causes of acquired proximal gastrointestinal obstruction in previously healthy children, despite their rarity.

    Remote organ failure occurs in cases of acute pancreatitis (AP); however, the reports on AP induced by pancreatic duct obstruction are rare. In this study we determined the effect of L-cysteine on pancreaticobiliary inflammation and remote organ damage in rats after pancreaticobiliary duct ligation (PBDL). AP was induced by PBDL in rats with 5/0 silk. Sixty rats were randomly divided into 4 groups. Groups A and B were sham-operated groups that received injections of saline or L-cysteine (10 mg/kg) intraperitoneally (15 rats in each group). Groups C and D were PBDL groups that received injections of saline or L-cysteine (10 mg/kg) intraperitoneally (15 rats in each group). The tissue samples of the pancreas and remote organs such as the lung, liver, intestine and kidney were subsequently examined for pathological changes under a light microscope. The samples were also stored for the determination of malondialdehyde and glutathione levels. Blood urea nitrogen (BUN), plasma amylase, ALT and AST levels were determined spectrophotometrically using an automated analyzer. Also, we evaluated the effect of L-cysteine on remote organ injury in rats with AP induced by retrograde infusion of 3.5% sodium taurocholate (NaTc) into the bile-pancreatic duct. Varying degrees of injury in the pancreas, lung, liver, intestine and kidney were observed in the rats 24 hours after PBDL. The severity of injury to the lung, liver and intestine was attenuated, while injury status was not changed significantly in the pancreas and kidney after L-cysteine treatment. Oxidative stress was also affected by L-cysteine in PBDL-treated rats. The concentration of tissue malondialdehyde decreased in the pancreas and remote organs of PBDL and L-cysteine administrated rats, and the concentration of glutathione increased more significantly than that of the model control group. However, L-cysteine administration reduced the severity of injury in remote organs but not in the pancreas in rats with Na

    Airway compression is a common problem in children with certain forms of congenital heart disease. Although various surgical approaches are available to overcome this form of airway obstruction, internal stenting is necessary in a minority of patients. It can be difficult to assess the success of stenting at the time of the procedure, and the interval to successful extubation is usually used as an outcome measure. Measurement of relevant parameters of respiratory physiology with flow-volume and volume-pressure loops permits immediate quantitative assessment of the adequacy of stenting. A 3-month-old infant who underwent bronchial stenting and physiological assessment at the time of the procedure is described. (orig.)

    Medical records, radiographs, and bronchial cytologic abnormalities of 65 cats with bronchial disease were reviewed. Bronchial disease was defined as abnormality of the lower airways to the exclusion of disease originating or mainly involving the alveoli, interstitium, vasculature, or pleura. Cats with bronchial disease were more likely to be female and older. Siamese cats were over represented and had more chronic disease. In order of frequency, the following clinical signs were reported: coughing, dyspnea, occasional sneezing, wheezing, and vomiting. Radiography revealed prominent bronchial markings, with some cats having collapse of the middle lobe of the right lung (n = 7), overinflation of the lungs (n = 9), or aerophagia (n = 13). Of 65 bronchial washes, 58 were considered exudative, with the predominant cell type being eosinophil in 24%, neutrophil in 33%, macrophage in 22%, and mixed population of cells in 21%. Cultures for bacteria were considered positive in 24% of the cats. Circulating eosinophilia was not helpful in predicting the predominant cell type in bronchial cytologic exudates. Hyperproteinemia without dehydration was present in a third of the cats, indicating an immunologic response. Half the cats had resolution of clinical signs, whereas half the cats required continuing medication with bronchodilators, antimicrobial agents, or corticosteroids

    Full Text Available Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles. BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to the atretic bronchus. We present a unique case of chronic pulmonary aspergillosis (CPA in a patient with BA with no evidence of immune dysfunction. The patient was treated initially with voriconazole and subsequently underwent surgical excision of the involved area. On follow-up, she has done extremely well with no evidence for recurrence. In summary, we describe the first case of chronic pulmonary aspergillosis in an immunocompetent patient with bronchial atresia.

    Purpose: The purpose of this study was to identify independent CT findings that correlated with pulmonary function tests (PFTs) in patients with obstructive airway diseases. Materials and methods: Sixty-eight patients with obstructive airway disease and 29 normal subjects (mean age, 52 years; 36 men and 61 women) underwent inspiratory and expiratory thin-section CT and PFTs. Patient with obvious emphysema was excluded. Two radiologists independently reviewed the images and semi-quantitatively evaluated lung attenuation (mosaic perfusion, air trapping) and airway abnormalities (extent and severity of bronchial wall thickening and bronchiectasis, bronchiolectasis or centrilobular nodules, mucous plugging). Univariate, multivariate and receiver operating characteristic (ROC) analyses were performed with CT findings and PFTs. Results: Forty-two patients showed obstructive PFTs, 26 symptomatic patients showed near-normal PFTs. On univariate analysis, air trapping and bronchial wall thickening showed highest correlation with obstructive PFTs such as FEV1.0/FVC, MMEF and FEF75 (r ranged from -0.712 to -0.782; p < 0.001), while mosaic perfusion and mucous plugging showed moderate correlation, and bronchiectasis, bronchiolectasis and nodules showed the least, but significant, correlation. Multiple logistic analyses revealed air trapping and bronchial wall thickening as the only significant independent determinants of obstructive PFTs. ROC analysis revealed the cut-off value of air trapping for obstructive PFTs to be one-third of whole lung (area under curve, 0.847). Conclusions: Our study confirmed air trapping and bronchial wall thickening are the most important observations when imaging obstructive PFTs. The cut-off value of air trapping for identifying obstructive PFTs was one-third of lung irrespective of inspiratory CT findings.

    Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

    The purpose of this investigation was to compare the response of human cell types (bronchial epithelial cells and fibroblasts and skin fibroblasts) to various DNA damaging agents. Repair of DNA single strand breaks (SSB) induced by 5 krads of X-ray was similar for all cell types; approximately 90% of the DNA SSB were rejoined within one hour. During excision repair of DNA damage from u.v.-radiation, the frequencies of DNA SSB as estimated by the alkaline elution technique, were similar in all cell types. Repair replication as measured by BND cellulose chromatography was also similar in epithelial and fibroblastic cells after u.v.-irradiation. Similar levels of SSB were also observed in epithelial and fibroblastic cells after exposure to chemical carcinogens: 7,12-dimethylbenz[a]anthracene; benzo[a]pyrene diol epoxide (BPDE); or N-methyl-N-nitro-N-nitrosoguanidine. Significant repair replication of BPDE-induced DNA damage was detected in both bronchial epithelial and fibroblastic cells, although the level in fibroblasts was approximately 40% of that in epithelial cells. The pulmonary carcinogen asbestos did not damage DNA. DNA-protein crosslinks induced by formaldehyde were rapidly removed in bronchial cells. Further, epithelial and fibroblastic cells, which were incubated with formaldehyde and the polymerase inhibitor combination of cytosine arabinoside and hydroxyurea, accumulated DNA SSB at approximately equal frequencies. These results should provide a useful background for further investigations of the response of human bronchial cells to various DNA damaging agents

    2008-02-15

    Chronic obstructive pulmonary disease (COPD) and sleep apnea-hypopnea syndrome (SAHS) are both common diseases affecting respectively 10 and 5% of the adult population over 40 years of age, and their coexistence, which is denominated overlap syndrome, can be expected to occur in about 0.5% of this population. A recent epidemiologic study has shown that the prevalence of SAHS is not higher in COPD than in the general population, and that the coexistence of the two conditions is due to chance and not through a pathophysiologic linkage between these two diseases. Patients with overlap have a more important sleep-related O(2) desaturation than do patients with COPD with the same degree of bronchial obstruction. They have an increased risk of developing hypercapnic respiratory insufficiency and pulmonary hypertension when compared with patients with SAHS alone and with patients with "usual" COPD. In patients with overlap, hypoxemia, hypercapnia, and pulmonary hypertension can be observed in the presence of mild to moderate bronchial obstruction, which is different from "usual" COPD. Therapy of the overlap syndrome consists of nasal continuous positive airway pressure or nocturnal noninvasive ventilation (NIV), with or without associated nocturnal O(2). Patients who are markedly hypoxemic during daytime (Pa(O(2)) < 55-60 mm Hg) should be given conventional long-term O(2) therapy in addition to nocturnal ventilation.

    Bronchial hygiene therapy is a standard part of the treatment of patients with cystic fibrosis (CF). Coughing alone promotes sputum expectoration and is probably the primary effective component of standard bronchial hygiene therapy. The purpose of this study was to determine whether substituting regular exercise, which also promotes coughing, for two of three daily bronchial hygiene treatments would affect the expected improvements in pulmonary function and exercise response in hospitalized patients with CF. Seventeen patients with CF hospitalized (means length of stay = 13.0 +/- 2.6 days) for an acute exacerbation of their pulmonary disease participated in the study. The patients were randomly assigned to either a group that participated in two cycle ergometer exercise sessions and one bronchial hygiene treatment session per day (EX Group [n = 9]) or a group that participated in three bronchial hygiene treatment sessions per day (PD Group [n = 8]). Pulmonary functions and responses to a progressive, incremental cycle ergometer exercise test were measured on admission and before discharge. Bronchial hygiene therapy consisted of postural drainage, in six positions, with chest percussion and vibration. Therapeutic exercise was of moderate intensity and was individually adjusted based on the patient's heart rate and arterial oxygen saturation response to the admission exercise test. Coughing was encouraged during and after all treatments. Pulmonary function and exercise response were significantly improved over the period of hospitalization in both groups; the improvements were the same in the two groups. These results indicate that, in some hospitalized patients with CF, exercise therapy may be substituted for at least part of the standard protocol of bronchial hygiene therapy.

    PATHOPHYSIOLOGY OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD): Chronic inflammation of the upper airways, pulmonary parenchyma and pulmonary vasculature is the characteristic feature of COPD. Two mechanisms besides inflammation are also involved: oxidative stress and imbalance between proteinases and antiproteinases. Cellular infiltration of the upper airways involved neutrophils, macrophages, T lymphocytes and eosinophils. Inflammatory mediators appear to play a crucial role in the interaction between inflammation and obstruction. PROPERTIES OF FENSPIRIDE: A nonsteroidal drug, fenspiride, exhibits interesting properties documented in vitro: anti-bronchoconstriction activity, anti-secretory activity, and anti-inflammatory activity (reduction in the activity of phospholipase A2 and release of proinflammatory leukotriens). Two french clinical trials have studied the efficacy of fenspiride in patients with acute excerbation or stable COPD and have demonstrated an improvement in the group treated with fenspiride compared with the placebo group.

    Lately the connection of Asthma and RSV drew the sufficient attention. The recurrent wheezing developed during the RSV in children is particularly frequent in the families having history of atopy. The decreased expression of INFgamma may play the role in the pathogenesis of RSV infection. The target of our research was the study of the rate of INFgamma during various clinical courses of RSV-infection and definition of its role in the pathogenesis of ARVI. 52 children with RSV-associated wheezing have been studied, who had first (32) or recurrent episode (20) of bronchial obstruction and whose families had occurrence of atopy. 52 children with non RSV-associated wheezing (III group) and 10 healthy children up to 12 months of age (IV group) were considered as the control groups. Children from all four groups were from families with the history of atopy. INFgamma was measured by enzyme immunoassay (ELISA). Comparison of two groups of wheezing children with RSV infection showed significant reduction of INFgamma level in the group of children with recurrent wheezing vs. the group with first episode of wheezing. INFgamma levels were significantly higher in the two control groups. During the acute respiratory infection induced by RS-virus, which proceeds with the obstruction of respiratory tract (wheezing), reduction of INFgamma was noted and higher frequency of wheezing episodes is associated with more prominent alteration.

The objective of this study was to investigate effects of vitamin-E, as a powerful antioxidant, on renal oxidative stress and metabolism defect induced by 24-hr unilateral ureteral obstruction (UUO. "nMethods: Anesthetized male Sprague-Dawley rats (n=10 in each group were sterilely operated to occlude the left ureter. In UUO+NS, we had a single dose normal saline injection and in UUO+VitE and UUO+OO groups, D-α-tocopherol (50 mg/kg, the main component of vitamin-E, and its vehicle (Olive Oil, respectively, were twicely infused I.P. before and after UUO-induction. There were also sham-operated and control groups. 24-hr after of UUO-induction, both kidneys were removed and stored in -70°C. To determine metabolism condition, the levels of ATP and ADP; and to evaluate redox state, the levels of malondialdehyde (MDA and ferric reducing/antioxidant power (FRAP of kidneys were assessed. "nResults: The comparisons between UUO+NS and sham groups indicated that UUO increased MDA (p<0.001 and ADP (p<0.05, but decreased FRAP, and ATP/ADP ratio in obstructed kidney (all p<0.001. In UUO+VitE group, MDA and FRAP were equal to their levels in sham group, while ATP, ADP and ATP/ADP ratio were not different from those of UUO+NS group in obstructed kidney. "nConclusion: Twenty four hour of UUO caused renal reduction in oxidative metabolism and elevations in reactive oxygen species; and administration of vitamin-E, although considerably ameliorated the oxidative stress, could not improve the defected metabolism.

    106 patients with inoperable malignant tumours constricting the central bronchial tree underwent endobronchial small-field radiotherapy with iridium-192 at high dose between June 1983 and September 1985. Treatment was performed using the computer-guided after-loading technique and a flexible bronchoscope under local anaesthesia. In complete occlusion of a bronchus by the tumour, a neodymium YAG-laser was applied (57 patients) to allow insertion of the afterloading probe. Endoscopy showed tumour regression in 75% of the patients, accompanied by clinical improvement. Pulmonary function tests, arterial blood gas analyses and pulmonary perfusion scans yielded a highly significant improvement of data after treatment. The procedure also proved effective upon exhaustion of external radiation. Apart from its positive palliation, endobronchial small-field radiotherapy using high doses of iridium-192 also has a curative effect, thus opening up a new approach to the therapy of advanced bronchial carcinoma.

    Reactive airway dysfunction syndrome, a type of occupational asthma without a latency period, is induced by irritating vapour, fumes or smoke. The present report is the first to describe a case of reactive airway dysfunction syndrome caused by acute exposure to dishwater detergent containing sodium metasilicate and sodium dichloroisocyanurate. The diagnosis was based on exposure data, clinical symptoms and signs, as well as respiratory function tests. A 43-year-old nonatopic male apprentice cook developed respiratory symptoms immediately after exposure to a cloud of detergent powder that was made airborne by vigorous shaking of the package. In spirometry, combined obstructive and restrictive ventilatory impairment developed, and the histamine challenge test revealed bronchial hyper-responsiveness. Even routine handling of a strongly caustic detergent, such as filling a dishwasher container, is not entirely risk free and should be performed with caution.

    Full Text Available Reactive airway dysfunction syndrome, a type of occupational asthma without a latency period, is induced by irritating vapour, fumes or smoke. The present report is the first to describe a case of reactive airway dysfunction syndrome caused by acute exposure to dishwater detergent containing sodium metasilicate and sodium dichloroisocyanurate. The diagnosis was based on exposure data, clinical symptoms and signs, as well as respiratory function tests. A 43-year-old nonatopic male apprentice cook developed respiratory symptoms immediately after exposure to a cloud of detergent powder that was made airborne by vigorous shaking of the package. In spirometry, combined obstructive and restrictive ventilatory impairment developed, and the histamine challenge test revealed bronchial hyper-responsiveness. Even routine handling of a strongly caustic detergent, such as filling a dishwasher container, is not entirely risk free and should be performed with caution.

    Positive expiratory pressure (PEP) is a technique used to enhance sputum clearance during acute exacerbations of chronic obstructive pulmonary disease (AECOPD). The impact of PEP therapy during acute exacerbations on clinically important outcomes is not clear. This study sought to determine the effect of PEP therapy on symptoms, quality of life and future exacerbations in patients with AECOPD. 90 inpatients (58 men; mean age 68.6 years, FEV(1) 40.8% predicted) with AECOPD and sputum expectoration were randomised to receive usual care (including physical exercise)±PEP therapy. The Breathlessness, Cough and Sputum Scale (BCSS), St George's Respiratory Questionnaire (SGRQ) and BODE index (Body mass index, airflow Obstruction, Dyspnoea, Exercise tolerance) were measured at discharge, 8 weeks and 6 months following discharge, and analysed via linear mixed models. Exacerbations and hospitalisations were recorded using home diaries. There were no significant between-group differences over time for BCSS score [mean (SE) at discharge 5.2 (0.4) vs 5.0 (0.4) for PEP and control group, respectively; p=0.978] or SGRQ total score [41.6 (2.6) vs 40.8 (2.8) at 8 weeks, p=0.872]. Dyspnoea improved more rapidly in the PEP group over the first 8 weeks (p=0.006), however these benefits were not observed at 6 months. Exacerbations (p=0.986) and hospitalisations (p=0.359) did not differ between groups. We found no evidence that PEP therapy during AECOPD improves important short-term or long-term outcomes. There does not appear to be a routine role for PEP therapy in the management of such individuals.

    To determine the value of bowel sounds analysis using an electronic stethoscope to support a clinical diagnosis of intestinal obstruction. Subjects were patients who presented with a diagnosis of possible intestinal obstruction based on symptoms, signs, and radiological findings. A 3M™ Littmann(®) Model 4100 electronic stethoscope was used in this study. With the patients lying supine, six 8-second recordings of bowel sounds were taken from each patient from the lower abdomen. The recordings were analysed for sound duration, sound-to-sound interval, dominant frequency, and peak frequency. Clinical and radiological data were reviewed and the patients were classified as having either acute, subacute, or no bowel obstruction. Comparison of bowel sound characteristics was made between these subgroups of patients. In the presence of an obstruction, the site of obstruction was identified and bowel calibre was also measured to correlate with bowel sounds. A total of 71 patients were studied during the period July 2009 to January 2011. Forty patients had acute bowel obstruction (27 small bowel obstruction and 13 large bowel obstruction), 11 had subacute bowel obstruction (eight in the small bowel and three in large bowel) and 20 had no bowel obstruction (diagnoses of other conditions were made). Twenty-five patients received surgical intervention (35.2%) during the same admission for acute abdominal conditions. A total of 426 recordings were made and 420 recordings were used for analysis. There was no significant difference in sound-to-sound interval, dominant frequency, and peak frequency among patients with acute bowel obstruction, subacute bowel obstruction, and no bowel obstruction. In acute large bowel obstruction, the sound duration was significantly longer (median 0.81 s vs 0.55 s, P = 0.021) and the dominant frequency was significantly higher (median 440 Hz vs 288 Hz, P = 0.003) when compared to acute small bowel obstruction. No significant difference was seen

    Chronic obstructive pulmonary disease (COPD) and the obstructive sleep apnoea-hypopnoea syndrome (OSAHS) are both common diseases affecting respectively 10 and 5% of the adult population over 40 years of age. Their coexistence, which is denominated "Overlap Syndrome", can be expected to occur in about 0.5% of this population. Two recent epidemiologic studies have shown that the prevalence of OSAHS is not higher in COPD than in the general population, and that the coexistence of the two conditions is due to chance and not through a pathophysiological linkage. Patients with "overlap" have a higher risk of sleep-related O(2) desaturation than do patients with COPD alone and the same degree of bronchial obstruction. They have an increased risk of developing hypercapnic respiratory failure and pulmonary hypertension when compared with patients with OSAHS alone and with patients with "usual" COPD. In patients with overlap, hypoxaemia, hypercapnia, and pulmonary hypertension can be observed in the presence of mild to moderate bronchial obstruction, which is different from "usual" COPD. Treatment of the overlap syndrome consists of nasal continuous positive airway pressure or nocturnal non-invasive ventilation (NIV), with or without nocturnal O(2). Patients who are markedly hypoxaemic during the daytime (PaO(2)<55-60 mmHg) should be given conventional long-term O(2) therapy in addition to nocturnal ventilation. Copyright 2010 SPLF.

    Purpose: Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002. Materials and methods: From October 1997 to September 2002 we studied six patients affected by pseudo-obstruction of the colon. The pseudo-obstruction was recurrent in two cases. Acute dilatation of the colon without radiologically-detectable organic obstruction was the inclusion criterion for the study. Results: Plain abdominal radiography revealed colon dilatation that extended to the splenic flexure in three patients, to the hepatic flexure in two patients, and confined to the transverse colon in one patient. None of the patients showed air-fluid levels of the small intestine. Conclusion: The most relevant clinical finding in Ogilvie's syndrome is abdominal distension, which arises suddenly, has a progressive course and reaches massive levels. The first-line diagnostic investigation is plain abdominal radiography which shows extreme colon dilatation without air-fluid levels of the small intestine. In three of our patients, conservative therapy alone was able to restore normal conditions within five days; two patients required decompressive colonoscopy, and one patient died from cardio-circulatory arrest after 48 hours.

As a consequence, myocardial ischemia is a relevant cause of death in these patients. We reviewed studies concerning the potential mechanisms of atherothrombosis in COPD. Bronchial inflammation spreads to the systemic circulation and is known to play a key role in plaque formation and rupture. In fact, C-reactive protein blood levels increase in COPD and provide independent prognostic information. Systemic inflammation is the first cause of the hypercoagulable state commonly observed in COPD. Furthermore, hypoxia is supposed to activate platelets, thus accounting for the increased urinary excretion of platelet-derived thromboxane in COPD. The potential metabolic risk in COPD is still debated, in that recent studies do not support an association between COPD and diabetes mellitus. Finally, oxidative stress contributes to the pathogenesis of COPD and may promote oxidation of low-density-lipoproteins with foam cells formation. Retrospective observations suggest that inhaled corticosteroids may reduce atherothrombotic mortality by attenuating systemic inflammation, but this benefit needs confirmation in ongoing randomized controlled trials. Physicians approaching COPD patients should always be aware of the systemic vascular implications of this disease.Keywords: COPD, atherothrombosis, cardiovascular risk, mortality

    Full Text Available The clinical features of laboratory-confirmed acute respiratory syncytial virus infection (ARSVI are described in 221 children of the age from 1 month to 5 years. Febrile fever has been recorded in 76% of patients with ARSVI, and significantly more often in children in the second year of life (92%, but the difference in the temerature or duration has not been found. 98% of children have had symptoms of the lower respiratory tract lesions. The most common ARSVI manifestations in the patients of the first year of life were obstructive diseases of the lower respiratory tract (obstructive bronchitis in 53% and bronchiolitis in 11% of children, in the patients of the second year of life — pneumonia (28%, p < 0,05 and catarrhal otitis (26%; p < 0,05. Bronchial obstruction syndrome in children of the first year of life was characterized by the significantly higher frequency (73% and the maximal duration (9,7 ± 1,08 days. The largest number of cases of the severe respiratory failure has been recorded among patients of the second year of life (3 degree of respiratory failure in 22% of patients, p < 0,05.

    Pneumonia is considered an independent entity in chronic obstructive pulmonary disease (COPD), to be distinguished from an infectious exacerbation of COPD. The aim of this study was to analyze the clinical characteristics and progress of the exacerbation of COPD (ECOPD) compared to pneumonia in COPD (PCOPD) patients requiring hospitalization. Prospective, longitudinal, observational cohort study including 124 COPD patients requiring hospital admission for lower respiratory tract infection. Patients were categorized according to presence of ECOPD (n=104) or PCOPD (n=20), depending on presence of consolidation on X-ray. Demographic, clinical, laboratory, microbiological and progress variables were collected. Patients with ECOPD showed more severe respiratory disease according to the degree of obstruction (P<.01) and need for oxygen therapy (P<.05). PCOPD patients showed increased presence of fever (P<.05), lower blood pressure (P<.001), more laboratory abnormalities (P<.05; leukocytosis, elevated CRP, low serum albumin) and increased presence of crepitus (P<.01). Microbiological diagnosis was achieved in 30.8% of cases of ECOPD and 35% of PCOPD; sputum culture yielded the highest percentage of positive results, predominantly Pseudomonas aeruginosa. Regarding the progress of the episode, no differences were found in hospital stay, need for ICU or mechanical ventilation. Our data confirm clinical and analytical differences between ECOPD and PCOPD in patients who require hospital admission, while there were no differences in subsequent progress.

    To characterize the thin-section computed tomographic (CT) appearance of bronchiolitis fibrosa obliterans syndrome in infants and young children after lung transplantation. Thin-section CT studies in six patients with bronchiolitis obliterans syndrome (age range, 2 months to 5 1/2 years) and in 15 control patients without obstructive airway disease (age range, 2 months to 7 years) who underwent bilateral lung transplantation were retrospectively reviewed. The thin-section CT scans were obtained during quiet sleep at a median of 24 months (range, 6-36 months) after transplantation. The CT studies were evaluated for mosaic perfusion, bronchial dilatation, bronchial wall thickening, and mucous plugging Final diagnoses in all patients were based pulmonary function test results. Thin-section CT findings in the six patients with clinically proved bronchiolitis obliterans syndrome were mosaic perfusion in five (83%) bronchial dilation in three (50%), and bronchial wall thickening in one (17%). Of the 15 control patients with normal pulmonary function test results, six (40%) had mosaic perfusion; none had bronchial dilatation or bronchial wall thickening. Mucous plugging was not seen in either group. Only the association of bronchial dilatation with bronchiolitis obliterans syndrome was significant (P = .02). Infants and young children with bronchiolitis obliterans syndrome after lung transplantation are more likely to have CT abnormalities than those with normal pulmonary function test results.

    Purpose: We report an unusual pattern of referred pain to the ipsilateral forehead and orbit observed during bronchial artery embolization (BAE) for massive hemoptysis due to pulmonary tuberculosis (TB) and postulate possible neural mechanisms for its occurrence.Methods: Seven men, from a series of 194 patients (171 men, 23 women) undergoing BAE (right bronchial artery 4, left 3) with gelatin sponge for control of massive hemoptysis due to pulmonary TB form the subject of this report.Results: Embolization was successful in achieving control of hemoptysis in these patients and there were no complications following the embolization. Transient, moderately severe, ipsilateral supraorbital and/or retroorbital pain occurred only during the injection of the gelatin sponge contrast mixture into the bronchial artery. The pain did not occur during the injection of heparinized saline or ionic contrast medium.Conclusions: Referred pain during BAE is an unusual phenomenon. Acute vessel distension triggering visceral sensations is probably the causative mechanism. Sympathetic afferents from the bronchi coursing through the posterior pulmonary plexus eventually pass to the trigeminal ganglion via the carotid sympathetic chain. The ophthalmic and maxillary divisions of the trigeminal nerve then mediate pain sensation to the ipsilateral forehead and orbit. Similarly, parasympathetic afferents from the pulmonary plexus crossing the nucleus of the spinal tract of the trigeminal nerve may be responsible for interexchange of impulses to the neurons in this nucleus. Sensory fibers of the ophthalmic and maxillary nerves relaying in this nucleus are then involved in this pain being referred to the forehead and orbit.

    Radioaerosol inhalation imaging (RII) has been used in radionuclide pulmonary studies for the past 20 years. The method is well accepted for assessing regional ventilation because of its usefulness, easy fabrication and simple application system. To evaluate its clinical utility in the study of impaired regional ventilation in bronchial asthma, we obtained and analysed RIIs in 31 patients (16 women and 15 men; age ranging 21-76 years) with typical bronchial asthma at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical college, from January, 1988 to August, 1989. Scintiscans were obtained with radioaerosol produced by a HARC(Bhabha Atomic Research Center, India) nebulizer with 15 mCi of 99m Tc-phytate. The scanning was performed in anterior, posterior and lateral projections following 5-minute inhalation of radioaerosol on sitting position. The scans were analysed and correlated with the results of pulmonary function study and the findings of chest radiography. Fifteen patients had concomitant lung perfusion image with 99m Tc-MAA. Follow-up scans were obtained in 5 patients after bronchodilator therapy. 1 he patients were divided into (1) attack type (4 patients), (2) resistant type (5 patients), (3) remittent type (10 patients) and (4) bronchitic type (12 patients). Chest radiography showed hyperinflation, altered pulmonary vascularity, thickening of the bronchial wall and accentuation of hasal interstitial markings in 26 of the 31 patients. Chest radiographs were normal in the remaining 5 patients. Regardless of type, the findings of RII were basically the same, and characterized by the deposition of radioaerosol in the central parts or in the main respiratory air ways along with mottled nonsegmental ventilation defects in the periphery. Peripheral parenchymal defects were more extensive than that of expected findings from clinical symptoms, pulmonary function test and chest radiograph. Broomstick sign was present in 1.7 patients

    This study aims at defining the incidence of rhino-bronchial syndrome (RBS) in children in order both to verify the influence of nasal obstructions on the disease and to determine therapeutic strategies which may cure the syndrome effectively at its early stage. The investigation includes 128 non-allergic children with obstructive disorders (adenoid hypertrophy, septal deviation, etc.) and rhino-sinus inflammations associated with bronchopulmonary diseases (asthma, chronic cough, bronchopulmonary infections). Medical and/or surgical treatment was chosen in consideration of the type and entity of the patients' main nasal pathology. At least 1 year follow-up was provided for each case to establish the improvement in the disorders affecting both the lower and upper airways. The results were statistically assessed. Medical and mainly surgical treatment always cured the upper airways disorders in patients with chronic nasal obstruction and rhino-sinus inflammation. Improvement of bronchopulmonary disease was reported in about half of the patients (49.4%). Statistically significant results were obtained only in the group with recurrent bronchopulmonary infections (80.9%, pobstruction and rhino-sinus infections. In the population studied, among the lower airways disorders, only infective bronchopulmonary inflammation showed a significant correlation in the assessment between lower and upper airways disorders. In order to prevent the progression of the syndrome to serious pathologic events of the lower airways, a prompt and effective treatment of children's nasal disorders is thus recommended.

    Chronic obstructive pulmonary disease (COPD) is the chronic respiratory disease with the most important burden on public health in terms of morbidity, mortality and health costs. For patients, COPD is a major source of disability because of dyspnea, restriction in daily activities, exacerbation, risk of chronic respiratory failure and extra-respiratory systemic organ disorders. The previous French Language Respiratory Society (SPLF) guidelines on COPD exacerbations were published in 2003. Using the GRADE methodology, the present document reviews the current knowledge on COPD exacerbation through 4 specific outlines: (1) epidemiology, (2) clinical evaluation, (3) therapeutic management and (4) prevention. Specific aspects of outpatients and inpatients care are discussed, especially regarding assessment of exacerbation severity and pharmacological approach. Copyright © 2017 SPLF.

    interface e experiência do fisioterapeuta.BACKGROUND AND OBJECTIVES: Chronic obstructive pulmonary disease (COPD is defined as a syndrome characterized by usually progressive chronic airflow limitation which is associated to a bronchial hyperresponsiveness and is partially reversible. Noninvasive mechanical ventilation is an alternative treatment for patients with COPD exacerbations. The objective of the literature reviews was to verify noninvasive mechanical ventilation benefits and complications in acute exacerbations of chronic obstructive pulmonary disease in patients. CONTENTS: This national and international's scientific literature review was developed according to criteria established for documentary research in the MedLine, LILACS, SciElo, PubMed and Cochrane, databases using the key words: chronic obstructive pulmonary disease and noninvasive mechanical ventilation. Inclusion criteria were articles published from 1995 to 2007; in English, Spanish and Portuguese; studies in the human model and with no gender restriction. CONCLUSIONS: Noninvasive mechanical ventilation can reduce partial pressure of carbon dioxide, improve gas exchange, alleviate symptoms as dyspnea caused by fatigue of the respiratory muscles, reduce duration of hospitalization, decrease need for invasive mechanical ventilation, reduce number of complications and also lessen hospital mortality. The main complications found were: facial skin erythema, claustrophobia, nasal congestion, face pain, eye irritation, aspiration pneumonia, hypotension, pneumothorax, aerophagia, hypercapnia, gastric insufflation, vomit, bronchoaspiration, morning headaches, face injuries, air embolism and, last but not least, discomfort of the patient. Noninvasive mechanical ventilation can be more effective in patients with moderate-severe exacerbations of COPD and these complications can be minimized by an adequate interface also by the contribution of the physiotherapist experience.

  10. Chronic obstructive pulmonary disease and obstructive sleep apnea. Association, consequences and treatment.

    Pronzato, C

    2010-12-01

    Obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) are two diseases that often co-exist within an individual. This co-existence, known as overlap syndrome (OS), is the result of chance rather than a pathophysiological linkage and epidemiological studies indicate a prevalence of 1% in adult males. Patients vith OS have a more important sleep-related O2 desaturation than COPD patients with the same degree of bronchial obstruction and show an increased risk of developing hypercapnic respiratory failure and pulmonary hypertension when compared with patients affected by only one of he diseases. COPD and OSAS are independent risk factors for cardiovascular events and their co-existence in OS probably increases this risk. Evidence of systemic inflammation in COPD and sleep apnea and consequentely OS, is interesting because it may contribute to the pathogenesis of cardiovascular diseases. Treatment consists of continuous positive airway pressure (CPAP) or non-invasive positive pressure ventilation (NIPPV), with or without associated O2, for correction of the upper airway obstructive episodes and hypoxemia during sleep.

    Objective: To evaluate the efficiency and safety of intraluminal stent as a treatment of malignant obstruction of digestive tract and esophago-bronchial fistula. Methods: In total 71 patients suffered with malignant obstruction or esophago-bronchial fistula were treated with permanent nickel-titanium alloy, partially covered stents. All the procedures were performed under DSA guidance. Inserted via the oral anal access, the stents were placed at the sites of obstructions or the fistulas. Esophagogram or colonogram were done before and post the intervention. The clinical efficiency was assessed by function of swallowing or defecation in follow-up. Results: In 62 patients (96.9%), function of swallowing was restored after the stent was placed in upper digestive tract without drinking triggered coughing. Symptoms were immediately relieved after the stent was placed in sigmoid colon or rectum. Displacement of stents was seen in 2 cases (2.8%); restenosis in 2 (2.8%); hoarse voice was noted in 1 case (1.4%); intense thoracic pain was complained in 2 cases (2.8%); mild pain was noted in 12 cases (16.9%); and massive hemorrhage was complicated in 1 case (1.4%). All complications were successfully controlled after proper treatment. Conclusion: It is an effective, easy and safe method to treat malignant obstruction of digestive tract or esophago-bronchial fistula using partially covered nickel-titanium alloy stent. (authors)

    Animal studies have been performed in 30 dogs in order to obtain information concerning typical patterns of cholescintigraphy in acute obstructive jaundice. In 14 the choledochus was ligated and in 16 galactosamine-hepatitis was induced as an experimental model for parenchymatous jaundice. The results suggest a number of diagnostic criteria in obstructive disease. (Auth.)

    Obstructive lung diseases like asthma or chronic obstructive lung diseases have a high prevalence and are one of the four most frequent causes of death. Obstructive lung diseases can be significantly influenced by the choice of anesthetic techniques and anesthetic agents. Basically, the severity of the COPD and the degree of bronchial hyperreactivity will determine the perioperative anesthetic risk. This risk has to be assessed by a thorough preoperative evaluation and will give the rationale on which to decide for the adequate anaesthetic technique. In particular, airway instrumentation can cause severe reflex bronchoconstriction. The use of regional anaesthesia alone or in combination with general anaesthesia can help to avoid airway irritation and leads to reduced postoperative complications. Prophylactic antiobstructive treatment, volatile anesthetics, propofol, opioids, and an adequate choice of muscle relaxants minimize the anesthetic risk, when general anesthesia is required In case, despite all precautions intra-operative bronchospasm occurs, deepening of anaesthesia, repeated administration of beta2-adrenergic agents and parasympatholytics, and a single systemic dose of corticosteroids represent the main treatment options.

    The classic auscultation with stethoscope is the established clinical method for the detection of lung diseases. The interpretation of the sounds depends on the experience of the investigating physician. Therefore, a new computer-based method has been developed to classify breath sounds from digital lung sound recordings. Lung sounds of 11 patients with one-sided pneumonia and bronchial breathing were recorded on both the pneumonia side and on contralateral healthy side simultaneously using two microphones. The spectral power for the 300-600 Hz frequency band was computed for four respiratory cycles and normalized. For each breath, the ratio R between the time-segments (duration = 0.1 s) with the highest inspiratory and highest expiratory flow was calculated and averaged. We found significant differences in R between the pneumonia side (R = 1.4 +/- 1.3) and the healthy side (R = 0.5 +/- 0.5; p = 0.003 Wilcoxon-test) of lung. In 218 healthy volunteers we found R = 0.3 +/- 0.2 as a reference-value. The differences of ratio R (delta R) between the pneumonia side and the healthy side (delta R = 1.0 +/- 0.9) were significantly higher compared to follow-up studies after recovery (delta R = 0.0 +/- 0.1, p = 0.005 Wilcoxon-test). The computer based detection of bronchial breathing can be considered useful as part of a quantitative monitoring of patients at risk to develop pneumonia.

    Bronchial asthma is a clinical syndrome with possible correlation to oxidative stress, therefore the effectiveness of some antioxidant drugs has been studied in management of chronic bronchial asthma. Methods: This study was carried out in the Al- Kadhimia Teaching Hospital between December 2008 to May 2009 on 56 patients of both sexes who were randomly allocated to 7 groups, plus 10 healthy volunteers as control group. Each group was given one of the following drugs: vitamin E, vitamin C, combination of vitamin E and C, selenium, zinc, allopurinol and garlic oil, in addition to their classical treatment of asthma and their pulmonary function tests were conducted as well as measuring the levels of serum zinc, calcium, and malondialdehyde (MDA) before and after treatment. Results: All asthmatic patients were suffering from oxidative stress and this was detected by measuring the level of serum MDA which was 2-3 folds more than the control group, and all antioxidants except allopurinol showed a beneficial effect of different degrees in the pulmonary function tests accompanied with clinical improvement of patients' condition and marked decrease in the number of daily attacks. Antioxidants can compensate the oxidative stress that correlates with asthma, can reduce the symptoms of asthma, and improve pulmonary functions. (author)

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    Background: Computed tomographic pulmonary angiography (CTPA) has been established as a first-line test in the acute pulmonary embolism (APE) diagnostic algorithm, but the assessment of the severity of APE by this method remains to be explored. Purpose: To retrospectively evaluate right ventricular (RV) dysfunction and severity in patients with APE without underlying cardiopulmonary disease using helical computed tomography (CT). Material and Methods: Seventy-three patients (35 men and 38 women) were divided into two groups according to the clinical findings: severe APE (n=22) and non-severe APE (n=51). Pulmonary artery CT obstruction index was calculated according to the location and degree of clots in the pulmonary arteries. Cardiovascular parameters including RV short axis and left ventricular (LV) short axis, RV short axis to LV short axis (RV/LV) ratio, main pulmonary artery, azygous vein, and superior vena cava diameters were measured. Leftward bowing of the interventricular septum, reflux of contrast medium into the inferior vena cava and azygous vein, and bronchial artery dilatation were also recorded. The results were analyzed by Mann-Whitney U test, x2 test, Spearman's rank correlation coefficient, and the area under the receiver operating characteristic curve (Az). Results: CT obstruction index in patients with severe APE (median 43%) was higher than that of patients with non-severe APE (median 20%). Comparison of cardiovascular parameters between patients with severe and non-severe pulmonary embolism showed significant differences in RV short axis, LV short axis, RV/LV ratio, RV wall thickness, main pulmonary artery diameter, azygous vein diameter, leftward bowing of the interventricular septum, and bronchial artery dilatation. The correlation between CT obstruction indexes and cardiovascular parameters was significant. Spearman's rank correlation coefficient was highest between RV/LV ratio and CT obstruction index. Az values were

    Patients with airways obstruction often find it difficult to clear excess lung secretions. Frequent coughing can clear the larger airways but may itself further damage the airways ciliated epithelium. Various physiotherapy regimes have been proposed yet objective evidence of their efficacy is sparse. Deposited aerosol particles - with an appropriate label for gamma imaging - can track clearance from different lung regions. Published reports have however tended to be equivocal in respect of clearance from the more distal conducting airways. Questions also arise as to coordination of transport rates at different levels of the bronchial tree. We therefore sought to re-assess requirements for effective analysis of physiotherapy-enhanced clearance to yield data on both peripheral and central airways clearance. (author)

    Closed duodenal loops may be made in dogs by ligatures placed just below the pancreatic duct and just beyond the duodenojejunal junction, together with a posterior gastro-enterostomy. These closed duodenal loop dogs die with symptoms like those of patients suffering from volvulus or high intestinal obstruction. This duodenal loop may simulate closely a volvulus in which there has been no vascular disturbance. Dogs with closed duodenal loops which have been washed out carefully survive a little longer on the average than animals with unwashed loops. The duration of life in the first instance is one to three days, with an average of about forty-eight hours. The dogs usually lose considerable fluid by vomiting and diarrhea. A weak pulse, low blood pressure and temperature are usually conspicuous in the last stages. Autopsy shows more or less splanchnic congestion which may be most marked in the mucosa of the upper small intestine. The peritoneum is usually clear and the closed loop may be distended with thin fluid, or collapsed, and contain only a small amount of pasty brown material. The mucosa of the loop may show ulceration and even perforation, but in the majority of cases it is intact and exhibits only a moderate congestion. Simple intestinal obstruction added to a closed duodenal loop does not modify the result in any manner, but it may hasten the fatal outcome. The liver plays no essential role as a protective agent against this poison, for a dog with an Eck fistula may live three days with a closed loop. A normal dog reacts to intraportal injection and to intravenous injection of the toxic substance in an identical manner. Drainage of this loop under certain conditions may not interfere with the general health over a period of weeks or months. Excision of the part of the duodenum included in this loop causes no disturbance. The material from the closed duodenal loops contains no bile, pancreatic juice, gastric juice, or split products from the food. It can be

    This study aimed to show that SHOX2 DNA methylation is a tumor marker in patients with suspected lung cancer by using bronchial fluid aspirated during bronchoscopy. Such a biomarker would be clinically valuable, especially when, following the first bronchoscopy, a final diagnosis cannot be established by histology or cytology. A test with a low false positive rate can reduce the need for further invasive and costly procedures and ensure early treatment. Marker discovery was carried out by differential methylation hybridization (DMH) and real-time PCR. The real-time PCR based HeavyMethyl technology was used for quantitative analysis of DNA methylation of SHOX2 using bronchial aspirates from two clinical centres in a case-control study. Fresh-frozen and Saccomanno-fixed samples were used to show the tumor marker performance in different sample types of clinical relevance. Valid measurements were obtained from a total of 523 patient samples (242 controls, 281 cases). DNA methylation of SHOX2 allowed to distinguish between malignant and benign lung disease, i.e. abscesses, infections, obstructive lung diseases, sarcoidosis, scleroderma, stenoses, at high specificity (68% sensitivity [95% CI 62-73%], 95% specificity [95% CI 91-97%]). Hypermethylation of SHOX2 in bronchial aspirates appears to be a clinically useful tumor marker for identifying subjects with lung carcinoma, especially if histological and cytological findings after bronchoscopy are ambiguous

    Selective coronary angiography with quantitative parameter assessment of the vessel stenosis geometry, which leads to acute coronary syndrome, was performed in 205 patients undergoing acute phase of myocardial infarction or unstable angina pectoris. Data for physicomechanical properties of the arterial vessels, blood and blood flow were used. The range of pressure variations accompanying the most frequently encountered ruptures of the atherosclerotic plaques was analyzed with physical model. It suggests that in 'lock' type plaques the ratio between the pressure on the wall of the normal vessel and that in the section outside the stenosis is considerably increased, especially in cases of enlarged vessel gauge. The results obtained show that the wall pressure closely to the plaque of a stenosed vessel with normal diameter of 3.5 mm exceeds 25 times the pressure within a normal vessel segment. (author)

    Chronic obstructive pulmonary disease (COPD) is divided into pulmonary emphysema and chronic bronchitis (CB). Emphysema is defined patho-anatomically as "permanent enlargement of airspaces distal to the terminal bronchiole, accompanied by the destruction of their walls, and without obvious fibrosis" (1). These lesions are readily identified and quantitated using computed tomography (CT), whereas the accompanying hyperinflation is best detected on plain chest X-ray, especially in advanced disease. The diagnosis of CB is clinical and relies on the presence of productive cough for 3 months in 2 or more successive years. The pathological changes of mucosal inflammation and bronchial wall thickening have been more difficult to identify with available imaging techniques. However, recent studies using Multi-detector row CT (MDCT) reported more reproducible assessment of air wall thickening.

    Objective: To evaluate the pulmonary metastatic tumor response to different ways of transcatheter arterial infusion. Methods: Thirty-five patients with pulmonary metastatic tumors were randomized divided into two groups: 15 patients with 49 lesions treated with bronchial arterial infusion (BAI) and 20 patients with 65 lesions treated with bronchial arterial infusion (BM)combined with pulmonary arterial infusion (PAI). The therapeutic response was assessed by the WHO evaluation criteria. Results: The total effective rate(CR + PR) of BAI was 65.3% (32/49), PAI + BAI was 61.5%(40/65) showing no statistical difference. The median survival time of BAI was 9 mo, BAI + PAI was 11.5 mo, demonstrating no statistical significance. Conclusions: BAI should be the primary treatment for pulmonary metastatic tumor. (authors)

    Full Text Available Placental growth factor (PlGF induces angiogenesis and promotes tissue repair, and plasma PlGF levels change markedly during acute myocardial infarction (AMI. Currently, the impact of obstructive sleep apnea (OSA in patients with AMI is a subject of debate. Our objective was to evaluate the relationships between PlGF levels and both the severity of acute coronary syndrome (ACS and short-term outcomes after ACS in patients with and without OSA.A total of 538 consecutive patients (312 OSA patients and 226 controls admitted for ACS were included in this study. All patients underwent polygraphy in the first 72 hours after hospital admission. The severity of disease and short-term prognoses were evaluated during the hospitalization period. Plasma PlGF levels were measured using an electrochemiluminescence immunoassay.Patients with OSA were significantly older and more frequently hypertensive and had higher BMIs than those without OSA. After adjusting for age, smoking status, BMI and hypertension, PlGF levels were significantly elevated in patients with OSA compared with patients without OSA (19.9 pg/mL, interquartile range: 16.6-24.5 pg/mL; 18.5 pg/mL, interquartile range: 14.7-22.7 pg/mL; p1, even after adjustment.The results of this study show that in patients with ACS, elevated plasma levels of PlGF are associated with the presence of OSA and with adverse outcomes during short-term follow-up.ClinicalTrials.gov NCT01335087.

    Bronchial rupture is a rare and serious complication of blunt chest trauma in children. The diagnosis of this injury is challenging and requires a high degree of clinical suspicion. It is frequently associated with other severe injuries that may draw the focus of attention away from this potentially catastrophic but treatable injury. The radiographic findings of bronchial rupture have been reported in very few series. We report the findings in two children with bronchial rupture diagnosed by CT, in whom CT resulted in a significant change in patient management. (orig.)

    Objective: To investigate the safety and the effect of superselective bronchial artery chemoembolization in the treatment of lung cancer. Methods: Three hundred and twenty-nine cases of lung cancer diagnosed by pathology and treated with simply bronchial artery infusion or superselective bronchial artery chemoembolization were investigated. (1) Simply bronchial artery infusion (n=221): 40-60 mg Cisplatin or 200-300 mg Carboplatin combined with 10-20 mg Mitomycin-C or 100-200 mg Etoposide were infused through the catheter which was placed in the bronchial artery trunk or intercostal-bronchial artery trunk after angiography, re-infusion was performed at 2-4 weeks intervals, 549 times of infusion were performed in 221 cases. (2) Superselective bronchial artery chemoembolization (n=108): microcatheter was superselectively inserted into the distal of feeding artery guided with road-map after selective angiography, then anticarcinogen (same as simply bronchial artery infusion) and embolic material were infused through microcatheter. 30-50 Gelfoam particles and/or 3-8 ml Lipiodol was used as embolic material. Chemoembolization was reperformed at 6-9 weeks intervals, 266 times of chemoembolization were done in 108 cases. Results: No severe complications such as spinal injury were found. 28 cases in 221 cases performed with simply bronchial infusion got complete response (CR), meanwhile, partial response (PR) in 79 cases, stable(S) in 88 cases, and processes (P) in 26 cases. The effective rate (CR + PR) was 48.4%, survival rate of 1 year and 2 years were 53.8% and 44.8%, respectively. In the 108 cases performed with superselective bronchial artery chemoembolization, there were 16 cases of CR, 53 cases of PR, 32 cases of S, and 7 cases of P. The effective rate (CR + PR) was 63.9%, survival rate of 1 year and 2 years were 77.8% and 65.7%, respectively. There were significant statistic differences in the effective rate and survival rate of 1 year and 2 years between the two

    To evaluate the impact of pulmonary arterial wall distensibility on the assessment of a computed tomography (CT) score in patients with nonmassive pulmonary embolism (PE) (ie, Mastora score). The arterial wall distensibility of five central pulmonary arteries (pulmonary artery trunk, right and left main pulmonary arteries, right and left interlobar pulmonary arteries) was studied on ECG-gated CT angiographic studies of the chest in 15 patients with no pulmonary arterial hypertension (group 1; mean pulmonary artery pressure: 17.2 mm Hg) and 9 patients with nonmassive PE (group 2), using 2D reconstructions at every 10% of the R-R interval. The systolic and diastolic reconstruction time windows of the examined arteries were identical in the 2 groups, obtained at 20% and 80% of the R-R interval, respectively. No statistically significant difference was observed between the mean values of the pulmonary arterial wall distensibility between the 2 groups, varying between 20.5% and 24% in group 1 and between 23.3% and 25.9% in group 2. The coefficients of variation of the average arterial surfaces were found to vary between 4.30% and 6.50% in group 1 and 4.2% and 8.4% in group 2. Except the pulmonary artery trunk in group 2, all the intraclass correlation coefficients were around 0.8 or greater than 0.8, that is the cutoff for good homogeneity of measurements. The pulmonary arterial wall systolic-diastolic distensibility does not interfere with the assessment of a CT obstruction score in the setting of nonmassive PE.

    Full Text Available Abstract Background Cigarette smoking is a leading cause of preventable death and a significant cause of lung cancer and chronic obstructive pulmonary disease. Prior studies have demonstrated that smoking creates a field of molecular injury throughout the airway epithelium exposed to cigarette smoke. We have previously characterized gene expression in the bronchial epithelium of never smokers and identified the gene expression changes that occur in the mainstem bronchus in response to smoking. In this study, we explored relationships in whole-genome gene expression between extrathorcic (buccal and nasal and intrathoracic (bronchial epithelium in healthy current and never smokers. Results Using genes that have been previously defined as being expressed in the bronchial airway of never smokers (the "normal airway transcriptome", we found that bronchial and nasal epithelium from non-smokers were most similar in gene expression when compared to other epithelial and nonepithelial tissues, with several antioxidant, detoxification, and structural genes being highly expressed in both the bronchus and nose. Principle component analysis of previously defined smoking-induced genes from the bronchus suggested that smoking had a similar effect on gene expression in nasal epithelium. Gene set enrichment analysis demonstrated that this set of genes was also highly enriched among the genes most altered by smoking in both nasal and buccal epithelial samples. The expression of several detoxification genes was commonly altered by smoking in all three respiratory epithelial tissues, suggesting a common airway-wide response to tobacco exposure. Conclusion Our findings support a relationship between gene expression in extra- and intrathoracic airway epithelial cells and extend the concept of a smoking-induced field of injury to epithelial cells that line the mouth and nose. This relationship could potentially be utilized to develop a non-invasive biomarker for

    To describe clinicofunctional features of essential and pulmogenic hypertension in chronic bronchoobstructive syndrome, 24-h profile of arterial pressure (AP), intracardiac hemodynamics and to propose differential diagnostic criteria for these hypertension forms. 24-h monitoring of arterial pressure (MAP), cardiohemodynamics, external respiration function (ERF) and blood gases examinations were made in 100 hypertensive subjects with chronic obstructive bronchitis and bronchial asthma. Significant differences were found between the groups of essential and pulmogenic hypertension by major values of MAP, echo-CG and ERF. Early disturbances in diastolic function of both the ventricles in essential and pulmonary hypertension in chronic bronchial obstruction arise long before clinical, x-ray and ECG signs of chronic pulmonary heart. The findings enable formulation of criteria of differential diagnosis of essential and pulmogenic hypertension and identify the latter as an independent nosological entity.

    Central airway obstruction caused by malignant or benign lesions, associated in some cases with hemoptysis, is a condition with high morbidity and mortality. The use of electrocautery by flexible bronchoscopy is an initial treatment option with immediate improvement of obstruction symptoms. It is as effective as Nd: YAG laser. To describe the usefulness of electrocautery in the management of central obstruction of the airway and hemoptysis. A retrospective, descriptive study of patients referred for management of central airway obstruction or associated hemoptysis. Diagnoses, symptoms (dyspnea, cough, and hemoptysis) and radiology before and after the procedures were analyzed. Eighteen patients aged 59 ± 12 years (66% males) were evaluated, registering 25 endoscopic procedures. Three conditions were found: partial or complete airway obstruction, hemoptysis and post lung transplant bronchial stenosis. Seventy two percent presented with dyspnea, 61% with cough and 33% with hemoptysis. Sixty six percent of patients had airway obstruction caused by malignant metastatic lesions. After electrocautery, 17 patients (94.4%) improved their symptoms and achieved complete airway clearing. Three patients had significant bronchial stenosis after lung transplant achieving subsequent clearing after electrocautery. Electrocautery during flexible bronchoscopy is an effective and safe procedure for the management of central airway obstruction and associated hemoptysis.

    Full Text Available Large bowel obstruction can result in significant morbidity and mortality, especially in cases of acute complete obstruction. There are many possible causes, the most common in adults being colorectal cancer. Endometriosis is a benign disease, and the most affected extragenital location is the bowel, especially the rectosigmoid junction. However, transmural involvement and acute occlusion are very rare events. We report an exceptional case of acute large bowel obstruction as the initial presentation of endometriosis. The differential diagnosis of colorectal carcinoma may be challenging, and this case emphasizes the need to consider intestinal endometriosis in females at a fertile age presenting with gastrointestinal symptoms and an intestinal mass causing complete large bowel obstruction.

    Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery. This fistula was not visible on the initial angiographic view and likely opened because of the hemodynamic changes resulting from the embolization. This case advocates for careful search for bronchial-to-coronary arterial fistulas and the need for repeated angiographic views during embolization procedures.

    Congenital lung malformations are increasingly detected before birth. However, bronchial atresia is rarely identified in utero and not always recognized in neonates. There are two types of atresia: (1) proximal, located at the level of the mainstem or the proximal lobar bronchi, which is extremely rare and usually lethal during pregnancy, causing a tremendous volume increase of the distal involved lung with secondary hypoplasia of the normal lung, and (2) peripheral, located at the segmental/subsegmental bronchial level, which may present as an isolated lesion or as part of a complex congenital malformation. Prenatal findings are mostly nonspecific. Postnatal exams show overinflated lung areas and focal bronchial dilations. The typical fluid-filled bronchoceles are not always observed in neonates but develop progressively in the first months of life. This pictorial essay describes the spectrum of imaging findings of bronchial atresia in fetuses, neonates and infants. (orig.)

    An 85-year-old, never-smoking man presented with exertional dyspnea. He had been exposed to silica dust in the work place. Chest computed tomography revealed bronchial wall thickening without emphysema. A pulmonary function test showed airflow obstruction without impaired gas transfer. Airway hyperresponsiveness and reversibility were not evident. A transbronchial lung biopsy showed findings suggestive of mineral dust exposure, such as fibrosis and slight pigmentation of bronchioles. He was diagnosed with non-smoking chronic obstructive pulmonary disease (COPD) due to occupational exposure to silica dust. His symptoms were improved using an inhaled long-acting bronchodilator. The clinical characteristics of non-smoking COPD are discussed in this report.

    The article deals with the problem of osteoporosis in patients with cardiovascular and broncho-obstructive disease. The risk factors and clinical functional features of osteoporosis are analyzed in patients with coronary heart disease, hypertension, chronic obstructive pulmonary disease, bronchial asthma. Indicators of bone mineral density in patients with cardiovascular and broncho-obstructive disease on average meet the criteria for osteopenia. Most examinees had a high risk of osteoporotic fractures as a result of significant reduction in bone mineral density. The presence of osteoporosis in patients with cardiovascular and broncho-obstructive pathology from the point of co-morbidity results in a syndrome of mutual aggravation that determines the need for a comprehensive diagnosis, treatment and prevention.

    Full Text Available Chronic obstructive pulmonary disease (COPD belongs to urgent medical and social problems of our time. Prognosis of COPD is often determined by a comorbidity, in particular obesity. The key chain, which unites COPD and obesity, is systemic inflammation, in the development of which the hormone of fatty tissue leptin plays an important role. The presence of receptors to leptin in the alveolar and bronchial epithelial cells, in smooth muscle tissue and submucous bronchial membrane allowes to assume that leptin takes pathogenetic part in COPD progression. The aim of our research was to estimate the leptin level in COPD patient and analyze changes of the respiratory function depending on it. Methods. We have been examined 26 patients with exacerbation of COPD (13 male and 13 female, 58 y.o. and 20 healthy people representative by gender, age and body mass. The level of serum leptin has been defined by the solid phase enzyme linked immunosorbent analysis, lung function – by computed testing. Results and conclusion. With the leptin level increase all of the lung function parameters progressively decreased, most significant - forced vital capacity and peak expiratory flow. Patients with hyperleptinemia had significantly lower measurements of forced expiratory volume in 1 second and vital lungs capacity. Severe degree of both obstructive and restrictive changes has been found more often among patients with hyperleptinemia and leptin level has been associated with the bronchial obstruction severity.

    We studied the effects of aerosolized as well as intravenous infusion of acetylcholine on bronchial blood flow in six anesthetized sheep. Intravenous infusion of acetylcholine, at a dose of 2 microg/kg, increased bronchial blood flow from 45 +/- 15 (SE) to 74 +/- 30 ml/min, and vascular conductance increased by 76 +/- 22%. In contrast, aerosolized acetylcholine at doses of 2 and 20 microg/kg decreased bronchial vascular conductance by approximately 10%. At an aerosolized dose of 200 microg/kg, the bronchial vascular conductance increased by approximately 15%, and there was no further increase in conductance when the aerosolized dose was increased to 2,000 microg/kg. Pretreatment of animals with a nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester hydrochloride, partially blocked the vasodilatory effects of intravenous acetylcholine and completely blocked the vasodilatory effects of high-dose aerosolized acetylcholine. These data suggest that aerosolized acetylcholine does not readily penetrate the vascular wall of bronchial circulatory system and, therefore, has minimal vasodilatory effects on the bronchial vasculature.

    Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

    The main indications for brachytherapy in the treatment of endobronchial cancer are dyspnea. postobstructive pneumonia and atelectasis, cough and hemoptysis resulting from broncus obstruction by exophytic intralumenal tumor growth. High Dose Rate intralumenal brachytherapy (HDRBT) may be combined with external beam radiotherapy (EBRT), in particular as almost all tumors are too large for HDRBT alone. From January 1992 to September 1995 we treated 268 patients affected by bronchial cancer, with EBRT combined with HDRBT. All patients were staged as IIIa-IIIb-IV but KPS was >60 and expectancy of life > than 3 months. After bronchoscopy and Tc simulation we found that almost 10% of patients were downstaged. Treatment was always realized delivering 60 Gy to the tumour volume and 50 Gy to the mediastinal structures with EBRT. Brachytherapy was performed during the radiotherapy course. In 38 patients HDRBT was realized just one time, at the beginning of EBRT, with a dose of 10 Gy calculated at 1cm from the central axis of the catheter. In 47 HDRBT was performed twice (at the beginning and at the end of EBRT) with a dose of 7 Gy calculated at 1 cm from the central axis. From 1994 we started a 3 fractions protocol (Timing: days 1.15.30) with a dose of 5 Gy calculated at 0.5 cm from the axis. Of the 183 patients introduced in the protocol 170 received the three fractions of HDRBT and 13 were excluded from the study for personal or clinical reasons. In 97% of cases the application did not need general anesthesia; local anesthesia has been sufficient supplemented by some drug for sedation and coughing. Anyway both bronchoscopy and HDRBT (with anterior-posterior and lateral chest X-ray) are performed in the same shielded room without the necessity of displacing the patient. In almost 60% of treatments we used just one endobronchial applicator. In case of tumor involvement of the carina, two applicators were introduced. By this a larger tumor volume can be treated with adequate

    Many patients with asthma or chronic obstructive pulmonary disease (COPD) have overlapping characteristics of both diseases. By spirometric definition, patients with both fixed airflow obstruction (AO) and bronchodilator reversibility or fixed AO and bronchial hyperresponsiveness can be considered to have asthma-COPD overlap syndrome (ACOS). However, patients regarded to have ACOS by spirometric criteria alone are heterogeneous and can be classified by phenotype. Eosinophilic inflammation, a history of allergic disease, and smoke exposure are important components in the classification of ACOS. Each phenotype has a different underlying pathophysiology, set of characteristics, and prognosis. Medical treatment for ACOS should be tailored according to phenotype. A narrower definition of ACOS that includes both spirometric and clinical criteria is needed.

    An intraluminal carcinoid tumor obstructing the left mainstem bronchus produced hypoxemia through alteration in ventilation/perfusion matching. Studies of regional lung function using 133-xenon (/sup 133/Xe) and a multiprobe computerized instrumentation system documented a reduction of perfusion to 22 percent and ventilation to 6 percent of the total. There was negligible washout of intravenously injected /sup 133/Xe from the left lung consistent with air trapping. Four days after left mainstem bronchial sleeve resection, perfusion, ventilation and washout of injected xenon had significantly improved and by four months postresection, all measurements were virtually normal, although complete restoration of perfusion in relation to ventilation was delayed. Regional lung function studied with a multiprobe system in this patient provided a clinical model for the study of ventilation and perfusion inter-relationships in large airway obstruction and demonstrated that a prolonged time may be required for return of perfusion to normal

    A 76-year-old woman was admitted to the ICU for a meningitis with rhombencephalitis due to Listeria monocytogenes. The treatment included amoxicillin (250 mg.kg-1.day-1) and gentamicin (3 mg.kg-1.day-1 over 6 days). Neurological outcome was favourable. However at the 14th day, an acute renal failure occurred, following macroscopic haematuria and milkiness urine. CT scan and sonography confirmed the diagnosis of obstructive renal failure with bilateral ureteral obstruction. Crystalluria caused by amoxicillin was suspected. Endoscopic ureteral insertion of double-J catheters permitted the recovery of a normal renal function.

    We assessed the ability of visualization of bronchial artery (BA) by using thin-slice axial images of 4-detector multidetector row CT in 65 patients with hemoptysis. In all patients, the origins of BA were well identified with observation of consecutive axial images with 1 mm thickness by paging method and bronchial arterial embolization (BAE) was performed successfully. Thin-slice axial images were considered to be useful to recognize BA and to perform BAE in patients with hemoptysis. (author)

    Non-invasive ventilation (NIV) is an evidence based management of acidotic, hypercapnic exacerbations of COPD. Previous national and international audits of clinical practice have shown variation against guideline standards with significant delays in initiating NIV. We aimed to map the clinical pathway to better understand delays and reduce the door-to-NIV time to less than 3 hours for all patients with acidotic, hypercapnic exacerbations of COPD requiring this intervention, by mandating the use of a guideline based educational management proforma.The proforma was introduced at 7 acute hospitals in North London and Essex and initiated at admission of the patient. It was used to record the clinical pathway and patient outcomes until the point of discharge or death. Data for 138 patients were collected. 48% of patients commenced NIV within 3 hours with no reduction in door-to-mask time during the study period. Delays in starting NIV were due to: time taken for review by the medical team (101 minutes) and time taken for NIV to be started once a decision had been made (49 minutes). There were significant differences in door-to-NIV decision and mask times between differing respiratory on-call systems, p < 0.05). The introduction of the proforma had no effect on door-to-mask times over the study period. Main reasons for delay were related to timely access to medical staff and to NIV equipment; however, a marked variation in practice within these hospitals was been noted, with a 9-5 respiratory on-call system associated with shorter NIV initiation times.

    We evaluated the longitudinal changes in lung function and the factors associated with FEV(1) changes over time in a sample of asthmatic subjects. FEV(1) measures were recorded every 3 months over a 5-year follow-up period. To compare all subjects independently of body size, FEV(1) values were normalized for the subject's height at the third power. We evaluated the possible effect of age, baseline FEV(1), disease duration, and FEV(1) variability on the rate of change of FEV(1). We studied 142 subjects with asthma diagnosed on the basis of validated clinical and functional criteria. FEV(1) showed a linear decay with aging in each subject. For a subject 1.65 m in height, the median overall FEV(1) decay was 40.9 mL/yr. FEV(1) decay slopes were significantly influenced by age and sex, being steeper in younger male subjects. A significant interaction was found between age and baseline FEV(1): the FEV(1) decay was significantly higher among younger asthmatics with a poorer baseline functional condition. A longer disease duration was associated with a lower FEV(1) slope. FEV(1) variability was strongly associated with an increased rate of FEV(1) decline. FEV(1) decline in patients with bronchial asthma is significantly influenced by baseline FEV(1), disease duration, and FEV(1) variability. Moreover, the rate of FEV(1) decline seems to increase in younger subjects only when the baseline function is poorer.

  14. Influence of age on bronchial mucociliary transport

    1979-01-01

    Mucociliary clearance was measured in 19 healthy non-smoking male subjects, aged between 21 and 69, by analysing the decrease in bronchial radioactivity of an aerosol of resin particles (mean diameter 7.4 +- 1.5 μm) labelled with sup(99m)Tc. The mucociliary clearance was expressed as the percentage of radioactivity eliminated after 1 h. The measurements were made on two occasions with an average time lapse of 5 weeks. The intra- and inter-individual coefficients of variation were 15.6% and 41.5% respectively. The mucociliary clearance was significantly lower (P 54 years) than that observed (mean 34.1 +- s.d. 14.1%) in the younger subjects (21 to 37 years). A significant negative correlation (r=-0.472, P<0.05) was obtained between the ages of the healthy subjects and their mucociliary clearance. However, the fact that the results varied considerably within each age group suggests that factors other than age may have an effect on the mucociliary clearance. (author)

Studies from the last two decades have provided strong evidence for a causal role of OSA in the development of systemic hypertension. The acute physiological changes that occur during apnea promote nocturnal hypertension and may lead to the development of sustained daytime hypertension via the pathways of sympathetic activation, inflammation, oxidative stress, and endothelial dysfunction. This review will focus on the acute hemodynamic disturbances and associated intermittent hypoxia that characterize OSA and the potential pathophysiological mechanisms responsible for the development of hypertension in OSA. In addition the epidemiology of OSA and hypertension, as well as the role of treatment of OSA, in improving blood pressure control will be examined.Keywords: obstructive sleep apnea, hypertension, intermittent hypoxia, ambulatory blood pressure, sympathetic activation

    Human Metapneumovirus (hMPV) is a recently reported agent of acute infection in the respiratory tract. It has been found in children as well as in young adults and elders. The clinical manifestations produced by hMPV are indistinguishable from those by common respiratory virus, and can evolve from asymptomatic infection into severe pneumonia. On the other hand, some authors have described cases of bronchial asthma exacerbation associated with hMPV infection. In this work we report a case of a child who presented a severe bronchial asthmatic crisis with a suspected viral associated infection. Immunofluorescence tests yielded negative results for sincitial respiratory virus, adenovirus, a-b influenza virus and parainfluenza 1, 2, 3, virus. In an attempt to detect the presence of hMPV, a RT-PCR was carried out to amplify sequences from both N and F genes. Using this approach, a positive result for hMPV was obtained. To our knowledge, this is the first description of a case of asthma exacerbation associated to hMPV in our region. In addition, these results are similar to previous reports where it was hypothesized that, like RSV, hMPV can trigger a respiratory chronic disease as asthma.

    Full Text Available The study involved 30 students with severe bronchial asthma and 30 children with moderate to severe course. Patients with severe bronchial asthma revealed a clear tendency to increase the relative content of interleukin 4 in peripheral blood, which indirectly indicates the severity of inflammation in the bronchi. Almost every second child suffering from severe bronchial asthma reported an increase in the concentration of immunoglobulin E (more than 545.3 IU/ml, and the odds ratio was 1.9 (95% CI 1.1–3.4. In the group of patients with severe bronchial asthma, cases of increased skin sensitivity to household allergens were significantly more frequent compared to the second group. Thus, the size of hyperemia over 15.0 mm was recorded in 81.5 % of children of the first group and only in 51.9 % of persons (Pϕ < 0.05 in the second one. Clinical and epidemiological risk and diagnostic value of individual indicators of atopic reactivity were determined to verify the phenotype of severe bronchial asthma.

Multidrug resistance-associated protein 1 (MRP1 is known to protect against toxic compounds and oxidative stress, and might play a role in protection against smoke-induced disease progression. We questioned whether MRP1-mediated transport is influenced by pulmonary drugs that are commonly prescribed in COPD.Methods: The immortalized human bronchial epithelial cell line 16HBE14o- was used to analyze direct in vitro effects of budesonide, formoterol, ipratropium bromide and N-acetylcysteine (NAC on MRP1-mediated transport. Carboxyfluorescein (CF was used as a model MRP1 substrate and was measured with functional flow cytometry.Results: Formoterol had a minor effect, whereas budesonide concentration-dependently decreased CF transport by MRP1. Remarkably, addition of formoterol to the highest concentration of budesonide increased CF transport. Ipratropium bromide inhibited CF transport at low concentrations and tended to increase CF transport at higher levels. NAC increased CF transport by MRP1 in a concentration-dependent manner.Conclusions: Our data suggest that, besides their positive effects on respiratory symptoms, budesonide, formoterol, ipratropium bromide, and NAC modulate MRP1 activity in bronchial epithelial cells. Further studies are required to assess whether stimulation of MRP1 activity is beneficial for long-term treatment of COPD.Keywords: bronchus epithelium, COPD, drugs, MRP1, multidrug resistance, oxidative stress

    From the paediatric point of view, we have undertaken two Delphi studies into bronchial asthma. The first is related to the consensus known as the consensus document of the five associations. The second is more recent and has been undertaken with GEMA (the Spanish Guidelines on the Management of Asthma). The aim of this paper is to carry out a descriptive study comparing the 2 Delphi processes and to objectively assess if in some way behaviour over the past two years has changed as far as expert opinion is concerned. In the consensus document those points giving rise to most controversy were the treatment of children under three years of age and treatment with immunotherapy in allergic asthma. It is also necessary to highlight how important it was at that particular point in time to define the phenotypes of wheezing and the predictive index of asthma in children of less than 3 years of age. Of the 52 questions in the questionnaire, in 13.6% the panel of experts reached no consensus in their positions. Following GEMA the Delphi methodology, 56 questions were asked in the first round of the questionnaire, and consensus was reached in 87.5%. As regards the paediatric part relating to diagnosis and treatment in children, agreement was reached on all the questions in the first round. Agreement was reached in 8.92% questions in the second round. Clinical guidelines and consensus documents can modify behaviour towards an illness, both in the diagnosis and treatment.

    Conclusion: A high index of suspicion is warranted for the overlap of OSA and asthma, particularly in the presence of obesity, GERD, and in patients with severe asthma. Individualized therapy addressing these moderating factors is warranted for optimal health outcomes. Recognition and treatment of OSA in asthmatics is an important element in improving asthma control.

    A 34-year-old man with persistent cough was admitted to our hospital. Bronchoscopic examination revealed a polypoid tumor with smooth surface which almost completely obstructed the right main bronchus. The tumor was removed by transbronchial snaring forceps and histologically confirmed as neurofibroma. Residual tumor was excised by biopsy forceps and further endoscopic Nd-YAG laser vaporization was performed. This is the first case in our country in which bronchoscopic treatment was performed for bronchial neurofibroma. Bronchoscopic removal might be the preferred treatment in the present case, although long-term follow-up is also required.

    Full Text Available Antibodies to IgE are a totally new class of medications currently used to enhance the supervision over severe persistent atopic bronchial asthma. Omalizumab is the most well studied, first and only medication of this group, which is recommended for the application and is allowed for treatment of uncontrolled bronchial asthma among adults and children aged 12 and over in different countries of the world, including Russia. High omalizumab assisted treatment costs, as well as the need in the monthly visits to the doctor for the omalizumab injections are justified for the patients, requiring repeat hospitalizations, emergency medical aid, using high doses of the inhalation and/or systemic glucocorticosteroids. The article reviews the criteria for the selection of patients fit for omalizumab assisted treatment.Key words: omalizumab, anti-ige-antibodies, bronchial asthma, allergic rhinitis, treatment, children.

    Full Text Available The effi ciency of lung transplantation is considerably limited by the complications associated with the bronchial pathologies. Despite the progress of the treatment methods, bronchial complications are still remaining as an actual problem in the postoperative period with frequency of occurrence from 7 to 29%. However, the bronchial stenosis are the most common bronchial complications after lung transplantation with mortality from 2 to 4%.Aim. To study an experience of our center of bronchial stenosis treatment in lung recipients. Materials and methods. 34 patients underwent lung transplantation from September 2014 to January 2017. 6 (16% of them had a stenosis of lobar or segmental bronchi from 84 to 494 postoperative day. 5 (83% of them have demonstrated multifocal lesions. In all of the cases there was performed an endoscopic bougienage, which involved a balloon dilatation and electrocoagulated incision of granular tissue under X-ray control. After that the patients were administrated by everolimus.Results. Restenosis was formed in 132,0 ± 94,2 postoperative day after primary treatment in all patients. In four cases (67% we used nitinol stent placement under X-ray control. There were no complications. In 3 cases stents were dislocated distally, so we needed to use repeated endoscopic bougienage to replace the stent. Using of everolimus has allowed to decrease the rate of restenosis, but it need future research.Conclusion. Distal bronchial stenosis after lung transplantation can be managed with endoscopic bougienage and stent placement. Adding everolimus has not signifi cantly affected the risk of frequency of restenosis.

    Purpose: We aimed to retrospectively evaluate bronchial and nonbronchial systemic arteries using multi-detector row helical computed tomographic (MDCT) angiography in patients with pulmonary disorders. Materials and Methods: Thirty-nine patients (24 men, 15 women; mean age, 63.4 years; range, 20-82 years) with congenital and acquired pulmonary disorders of the bronchial and nonbronchial systemic arteries underwent multi-detector row helical computed tomographic angiography of the thorax using a 16-detector row scanner. Each of these patients had experienced an episode of hemoptysis. Computed tomographic angiogram data, which included maximum intensity projections, multiplanar reconstruction, and three-dimensional volume-rendered images, were used to retrospectively analyse the characteristics of the bronchial and nonbronchial systemic arteries. Results: We identified a total of 128 bronchial arteries (76 on the right side and 52 on the left) in 39 patients. We detected 42 nonbronchial systemic artery branches, including 19 internal mammary artery branches, 8 subclavian artery branches, 8 inferior phrenic artery branches, 5 intercostal artery branches, 1 thyrocervical trunk branch, and 1 celiac trunk branch. Thirty-five dilated and tortuous nonbronchial systemic arteries entered into the lung parenchyma and extended down to the lesions. Every case, except the one case of sequestration, was associated with pleural thickening where the vascular structures passed through the extrapleural fat. Conclusions: The variations in both the bronchial artery anatomy and the location and type of the nonbronchial arteries were great. Nonbronchial arteries may be a significant source of hemoptysis. MDCT angiography can be used to detect detailed anatomical information about the origins and courses of bronchial and nonbronchial systemic arteries and their pathophysiologic features.

    Diagnostic and therapeutic problems in a patient with ectopic ACTH syndrome caused by a malignant bronchial adenoma are discussed. Persistent Cushing's syndrome was present following apparent total adrenalectomy, but radioactive scanning with 131I-19-iodocholesterol showed the presence of residual adrenal tissue in the right suprarenal bed. Amelioration of the hypercortisolism occurred after removal of the bronchial adenoma. A paradoxical elevation of adrenocortical activity followed administration of dexamethasone and data are presented which suggest that periodic secretion of ACTH accounted for this phenomenon.

    To detect abnormalities of the lower respiratory tract (trachea, principal bronchi, and lobar bronchi) in brachycephalic dogs by use of endoscopy, evaluate the correlation between laryngeal collapse and bronchial abnormalities, and determine whether dogs with bronchial abnormalities have a less favorable postsurgical long-term outcome following correction of brachycephalic syndrome. Prospective case series study. 40 client-owned brachycephalic dogs with stertorous breathing and clinical signs of respiratory distress. Brachycephalic dogs anesthetized for pharyngoscopy and laryngoscopy between January 2007 and June 2008 underwent flexible bronchoscopy for systematic evaluation of the principal and lobar bronchi. For dogs that underwent surgical correction of any component of brachycephalic syndrome, owners rated surgical outcome during a follow-up telephone survey. Correlation between laryngeal collapse and bronchial abnormalities and association between bronchial abnormalities and long-term outcome were assessed. Pugs (n = 20), English Bulldogs (13), and French Bulldogs (7) were affected. A fixed bronchial collapse was recognized in 35 of 40 dogs with a total of 94 bronchial stenoses. Abnormalities were irregularly distributed between hemithoraces; 15 of 94 bronchial abnormalities were detected in the right bronchial system, and 79 of 94 were detected in the left. The left cranial bronchus was the most commonly affected structure, and Pugs were the most severely affected breed. Laryngeal collapse was significantly correlated with severe bronchial collapse; no significant correlation was found between severity of bronchial abnormalities and postsurgical outcome. Bronchial collapse was a common finding in brachycephalic dogs, and long-term postsurgical outcome was not affected by bronchial stenosis.

    Purpose To quantify regional lung ventilation in healthy volunteers and patients with severe asthma (both before and after thermoplasty) by using a combination of helium 3 (3He) magnetic resonance (MR) imaging and computed tomography (CT), with the intention of developing more effective image-guided treatments for obstructive lung diseases. Materials and Methods With approval of the local institutional review board, informed consent, and an Investigational New Drug Exemption, six healthy volunteers and 10 patients with severe asthma were imaged in compliance with HIPAA regulations by using both multidetector CT and 3He MR imaging. Individual bronchopulmonary segments were labeled voxel by voxel from the CT images and then registered to the 3He MR images by using custom software. The 3He signal intensity was then analyzed by evaluating the volume-weighted fraction of total-lung signal intensity present in each segment (segmental ventilation percentage [SVPsegmental ventilation percentage]) and by identifying the whole-lung defect percentage and the segmental defect percentage. Of the 10 patients with asthma, seven received treatment with bronchial thermoplasty and were imaged with 3He MR a second time. Changes in segmental defect percentages and whole-lung defect percentages are presented. Results Ventilation measures for healthy volunteers yielded smaller segment-to-segment variation (mean SVPsegmental ventilation percentage, 100% ± 18 [standard deviation]) than did the measures for patients with severe asthma (mean SVPsegmental ventilation percentage, 97% ± 23). Patients with asthma also demonstrated larger segmental defect percentages (median, 13.5%; interquartile range, 8.9%–17.8%) than healthy volunteers (median, 6%; interquartile range, 5.6%–6.3%). These quantitative results confirm what is visually observed on the 3He images. A Spearman correlation of r = −0.82 was found between the change in whole-lung defect percentage and the number of days between

    Objective: The study was carried out to evaluate the role of serum eosinophil cationic protein (ECP) as a biological marker for the diagnosis and to assess the severity of bronchial asthma. Methodology: This observational cross-sectional study was conducted among 70 bronchial asthma patients and 45 disease controls (tuberculosis-15, chronic obstructive pulmonary disease-15, interstitial lung disease-15) enrolled from patients attending the outpatient department of the National Institute of Disease of the Chest and Hospital (NIDCH), Dhaka, Bangladesh during July 2010 to June 2011. Global Initiative of Asthma Management and Prevention (GINA) criteria were followed for selection of both atopic and non-atopic patients with intermittent or persistent (mild, moderate and severe) asthma. Serum level of eosinophil cationic protein (ECP), IgE, forced expiratory volume in 1 second (FEV 1% predicted) and circulatory eosinophil (CE) count were estimated. Results: Mean serum ECP level (28.8 +- 42.9 vs. 6.82 +- 3.5 ng/mL; P<0.001), IgE level (383.59 - 225.3 vs. 135 +- 131.8 IU/mL; P<0.001) and percent circulatory eosinophil count (9.95 +- 3.7 vs. 5.95 +- 1.4; P<0.024) were all found significantly raised among asthma patients than disease controls but % FEV1 was equivocal. All grades of persistent asthma patients had significantly (P<0.025 and P<0.002) higher mean ECP level than intermittent cases but serum IgE level and CE count did not differ significantly. FEV1 % predicted correlated well among moderate and severe persistent asthma but was equivocal for intermittent and mild persistent cases. Conclusion: This study has reinforced that serum eosinophil cationic protein is a dependable biological marker with more discriminatory power over other indicators for bronchial asthma and to assess its severity.

    To assess the efficacy of emergency extracorporeal shockwave lithotripsy (eSWL) as first-line treatment in patients with acute colic due to obstructive ureteral stone. 74 patients were randomized to emergency SWL within 12 hours (eSWL group) and deferred SWL later than 3 days (dSWL group). Follow-up included ultrasound, KUB (Kidney-Ureter-Bladder) radiography and CT (computed tomography) scan at 24 hours, 7 days, 1 and 3 months from the treatment. When necessary, repeated SWL (re-SWL) or ureteroscopy (auxiliary-URS) was performed. Preoperative and postoperative data were compared and stone free rates (SFR) and efficiency quotients (EQ) were evaluated. Analyses were performed using SAS software. Complete data of 70 patients were collected. 36 underwent eSWL and 34 dSWL. The mean patient age was 48.7. Mean stone size was 9.8 mm (CI 95%, 8.9-10.8). 25 (35.7%) were proximal and 45 (64.3%) distal. Mean SWL energy was 19.2 kV (CI 95%, 18.5-19.9) and mean number of shocks was 2657 (CI 95%, 2513-2802). eSWL patients needs less auxiliary-URS than dSWL patients (13.9% vs 44.1%, p=0.039) and less re-SWL sessions (8.3% vs 32.4%, p=0.093). SFR at 24 hours was 52.8% and 11.8% (p<0.001) and the EQ at 3 months was 79.1% and 57.5% in the eSWL and dSWL group respectively. Patients from the dSWL group spent more time in the hospital (2.21 vs 1.36 days, p=0.046) and complication rates between the two groups were similar. eSWL is a safe procedure and delivers high SFR even within 24 hours especially for <10mm stones. It is able to reduce the number of auxiliary procedures and hospitalization.

  15. Alterations in the expression of the NF-κB family member RelB as a novel marker of cardiovascular outcomes during acute exacerbations of chronic obstructive pulmonary disease.

    Directory of Open Access Journals (Sweden)

    Laura Labonté

    Full Text Available Chronic obstructive pulmonary disease (COPD exacerbations are acute events of worsened respiratory symptoms and enhanced inflammation partly mediated by NF-κB activation. RelB, an NF-κB family member, suppresses cigarette smoke-induced inflammation but its expression in COPD is unknown. Moreover, there is no information on its association with clinical features of COPD. The objectives of this study were to assess RelB expression relative to markers of inflammation as well as its association with cardiovascular and pulmonary features of COPD patients at stable-state and exacerbation.Data from 48 COPD patients were analyzed. Blood samples were collected from stable-state and exacerbating patients. After RNA isolation, quantitative real-time polymerase chain reaction (qRT-PCR was performed to assess RelB, Cox-2, IL-8 and IL-1β mRNA expression and their associations with measured clinical variables.Of the 48 COPD subjects, 18 were in stable-state and 30 were in exacerbation. RelB mRNA expression was lower than that of Cox-2, IL-8, and IL-1β in all cases (all p<0.001, except for IL-8 at exacerbation (p = 0.22. Cox-2, IL-8 and IL-1β were significantly associated with clinical features of patients in both stable-state and at exacerbation. There was no association with RelB expression and any clinical features in COPD subjects at stable-state. RelB mRNA levels were significantly associated with cardiovascular events such as systolic blood pressure during exacerbation.RelB mRNA expression is lower than that of the other inflammatory mediators. Expression of Cox-2, IL-8 and IL-1β were related to clinical features in both stable-state and at exacerbation. However, RelB expression was associated with clinical features of patients only during exacerbation, suggesting that RelB may represent a novel marker of health outcomes, in particular cardiovascular, during exacerbation in COPD.

    Emily G Notch

    Full Text Available Arsenic is the number one contaminant of concern with regard to human health according to the World Health Organization. Epidemiological studies on Asian and South American populations have linked arsenic exposure with an increased incidence of lung disease, including pneumonia, and chronic obstructive pulmonary disease, both of which are associated with bacterial infection. However, little is known about the effects of low dose arsenic exposure, or the contributions of organic arsenic to the innate immune response to bacterial infection. This study examined the effects on Pseudomonas aeruginosa (P. aeruginosa induced cytokine secretion by human bronchial epithelial cells (HBEC by inorganic sodium arsenite (iAsIII and two major metabolites, monomethylarsonous acid (MMAIII and dimethylarsenic acid (DMAV, at concentrations relevant to the U.S.Neither iAsIII nor DMAV altered P. aeruginosa induced cytokine secretion. By contrast, MMAIII increased P. aeruginosa induced secretion of IL-8, IL-6 and CXCL2. A combination of iAsIII, MMAIII and DMAV (10 pbb total reduced IL-8 and CXCL1 secretion. These data demonstrate for the first time that exposure to MMAIII alone, and a combination of iAsIII, MMAIII and DMAV at levels relevant to the U.S. may have negative effects on the innate immune response of human bronchial epithelial cells to P. aeruginosa.

    2003-03-01

    To investigate if extracts from dried ivy leaves (Hedera helix L.) are effective in the treatment of chronic airway obstruction in children suffering from bronchial asthma. Systematic review of trials documented in the literature with re-analysis of original data. 5 randomized controlled trials investigating the efficacy of ivy leaf extract preparations in chronic bronchitis, 3 of which were conducted in children and met our selection criteria. One compared ivy leaf extract cough drops to placebo, one compared suppositories to drops and one tested syrup against drops. Body-plethysmographic and spirometric measures. Drops were significantly superior to placebo in reducing airway resistance (primary outcome measure; p = 0.04 two-sided) and descriptively superior in all other 'objective' measures. For syrup and suppositories, at least 54%, resp. 35% of the effect against placebo were preserved. The trials included in this review indicate that ivy leaf extract preparations have effects with respect to an improvement of respiratory functions of children with chronic bronchial asthma, but more far-reaching conclusions can hardly be drawn because of a meagre database, including the fact that only one primary trial included a placebo control. Further research, particularly into the long-term efficacy of the herbal extract, is needed.

    2016-09-01

    Full Text Available The aim of the study was to assess the role of nitric oxide metabolites in the development of endothelium dysfunction in children with persistent bronchial asthma in acute period and during remission Material and methods. Fifty eight children aged 6–17 years old suffering from persistent bronchial asthma in the period of exacerbation and remission of disease and 15 healthy children of control group have been exa­mined in order to evaluate the role of the metabolites of nitric oxide levels for the development of endothelium dysfunction in the children with persistent bronchial asthma. There were determined serum blood S-nitrosothiol, NO2, NO3, the intima-media complex by the ultrasound duplex scanning and endothelium-dependent dilation status of the brachial artery by cuff probe. Results. It showed a reduction in the levels of nitric oxide metabolites and endothelium-dependent dilation of the brachial artery, intima-media thickening in the period of exacerbation. There was revealed a significant increase in the levels of nitric oxide metabolites and endothelium-dependent dilation of the brachial artery compared with the period of exacerbation, but these findings are still lower in comparison with the control group, which indicates the presence of persistent changes in the vascular wall. Conclusion. The nitric oxide metabolites as well as the carotid intimal medial thickness and endothelium-dependent dilation of brachial artery should be marders of endothelium dysfunction in the children with bronchial asthma.

    Unilateral acute pulmonary oedema (APO) is a rare radioclinical finding. It occurs secondary to multiple specific and rare pathological processes. Functional ischemic mitral regurgitation (FIMR) secondary to myocardial necrosis is one of the rare aetiologies involved in its pathogenesis. This concerns a 94-year-old male patient with a history of myocardial infarction who presented with a clinical picture of unilateral APO secondary to functional mitral regurgitation as a complication of myocardial necrosis. In addition to the clinical presentation and unilateral radiological findings, the diagnosis was based essentially on the electrocardiographic tracing, as well as changes in cardiac enzyme levels and transthoracic echocardiogram coupled with Doppler tissue imaging. This resulted after ruling out many differential diagnoses. Unilateral APO secondary to functional mitral regurgitation often presents diagnostic challenges and problems of initial management for the clinician. There are multiple aetiologies of acute unilateral pulmonary oedema, namely mechanical (re-expansion), lesional, vascular, bronchial obstructions, as well as iatrogenic causes, as is the case with some lung transplantations. As with all cases of APO, the treatment is based mainly on diuretics with high-flow oxygen therapy in association with an anticoagulant, which is usually effectively combined with a platelet aggregation inhibiting drug and sometimes with vasodilators and beta-blockers. Surgical treatment with valvuloplasty or valvular replacement appears to be the most effective means for preventing relapse.

    prevalence of severe exacerbations and impact of asthma on severe exacerbations, especially in patients with mild-to-moderate COPD.Methods: Patients with mild-to-moderate COPD (≥40 years were extracted from Korean National Health and Nutrition Examination Survey data (2007–2012 and were linked to the national health insurance reimbursement database to obtain medical service utilization records.Results: Of the 2,397 patients with mild-to-moderate COPD, 111 (4.6% had severe exacerbations over the 6 years (0.012/person-year. Severe exacerbations were more frequent in the COPD patients with concomitant self-reported physician-diagnosed asthma compared with only COPD patients (P<0.001. A multiple logistic regression presented that asthma was an independent risk factor of severe exacerbations in patients with mild-to-moderate COPD regardless of adjustment for all possible confounding factors (adjusted odds ratio, 1.67; 95% confidence interval, 1.002–2.77, P=0.049. In addition, age, female, poor lung function, use of inhalers, and low EuroQoL five dimensions questionnaire index values were independently associated with severe exacerbation in patients with mild-to-moderate COPD.Conclusion: In this population-based study, the prevalence of severe exacerbations in patients with mild-to-moderate COPD was relatively low, compared with previous clinical interventional studies. Coexisting asthma significantly impacted the frequency of severe exacerbations in patients with mild-to-moderate COPD, suggesting application of an exacerbation preventive strategy in these patients.

    Background With the recent emergence of conjugated bile acids as signaling molecules in cancer, a murine model of obstructive jaundice by cholestasis with long-term survival is in need. Here, we investigated the characteristics of 3 murine models of obstructive jaundice. Methods C57BL/6J mice were used for total ligation of the common bile duct (tCL), partial common bile duct ligation (pCL), and ligation of left and median hepatic bile duct with gallbladder removal (LMHL) models. Survival was assessed by Kaplan-Meier method. Fibrotic change was determined by Masson-Trichrome staining and Collagen expression. Results 70% (7/10) of tCL mice died by Day 7, whereas majority 67% (10/15) of pCL mice survived with loss of jaundice. 19% (3/16) of LMHL mice died; however, jaundice continued beyond Day 14, with survival of more than a month. Compensatory enlargement of the right lobe was observed in both pCL and LMHL models. The pCL model demonstrated acute inflammation due to obstructive jaundice 3 days after ligation but jaundice rapidly decreased by Day 7. The LHML group developed portal hypertension as well as severe fibrosis by Day 14 in addition to prolonged jaundice. Conclusion The standard tCL model is too unstable with high mortality for long-term studies. pCL may be an appropriate model for acute inflammation with obstructive jaundice but long term survivors are no longer jaundiced. The LHML model was identified to be the most feasible model to study the effect of long-term obstructive jaundice. PMID:27916350

    Two patients presented with recurrent, massive haemoptysis. Arteriography, including thoracoabdominal aortograms, revealed in both cases large non-bronchial collaterals arising from the left gastric artery. In the first case the non-bronchial collateral supplied the upper left lobe and in the second case it supplied the middle right lobe. Percutaneous embolisation of bronchial and non-bronchial collateral branches has become an accepted procedure in controlling massive or recurrent haemoptysis. Accurate identification of the non-bronchial collateral arterial feeders is essential for successful embolotherapy. (orig.)

    Purpose: To establish a protocol for and to assess the value of helical CT in the imaging of the bronchial tree. Material and Methods: Noncontrast helical CT was performed in 30 patients undergoing fiberoptic bronchoscopy for different reasons. Different protocols were compared; they included overlapping 10 mm, 5 mm, or 3 mm slices and non-tilted, cephalad or caudal tilted images. Ordinary cross-sectional and multiplanar 2D reformats were applied for visualization of the bronchial branches. The effect of increasing the helical pitch was tested in one patient. Results: A total of 92.1-100% of the segmental bronchi present in the helical acquisitions were identified by the different protocols. The collimation had no significant impact on the identification of the bronchial branches, but utilization of 3-mm overlapping slices made it easier to distinguish the nearby branches and provided better longitudinal visualization of the bronchi in 2D reformats. The tilted scans illustrated the disadvantage of not covering all segmental bronchi in one breath-hold. An increase of the pitch from 1 to 1.5 did not cause noticeable blurring of the images. CT and bronchoscopic findings correlated well in the area accessible to bronchoscopy, but CT detected 5 additional pathological lesions (including 2 cancers) in the peripheral lung. Conclusion: Helical CT supplemented with bronchography-like 2D reformats provides an effective method complementary to bronchoscopy in the examination of the bronchial tree. (orig.)

    In a prospective study of all patients with bronchial cancer in the city of Malmoe, all patients considered for surgery were examined with regard to overall function (conventional spirometry) and regional lung function (133-Xe-radiospirometry). Out of 116 consecutive cases examined with 133-Xe-radiospirometry before surgery,

    Conclusions: Vitamin D deficiency was highly prevalent in asthmatic patients, there was a strong correlation between asthma severity and 25(OH vitamin D concentrations and there was a direct and a positive significant correlation between vitamin D levels and pulmonary function tests in asthmatic patients, so the measurement of serum vitamin D levels in patients with bronchial asthma is very useful.

    Background: Allergic bronchopulmonary aspergillosis (ABPA) occurs in patients with asthma and cystic fibrosis. When aspergillus fumigatus spores are inhaled they grow in bronchial mucous as hyphae. It occurs in non immunocompromised patients and belongs to the hypersensitivity disorders induced by Aspergillus.

  10. Advice concerning the early diagnosis of bronchial carcinoma

    Bronchial carcinoma is in the Netherlands for men the most frequent type of cancer; the incidence in women is rising. In the Netherlands nowadays, per year about 7100 persons die of this disease which therefore constitutes an important public health problem. The request of advice asks - among other things - whether in the future the periodical X-ray examination of the thorax for the detection of tuberculosis of persons over 40 years can be continued for presymptomatic cases of bronchial carcinoma. The available relevant literature does not yet give indications that periodical mass radiography has any influence on the morbidity and mortality of the disease. On the other hand, literature describing clinical experience shows that the prognosis of patients with bronchial carcinoma, detected in an early presymptomatic stage, is essentially better than in the case of patients with symptomatic disease. A critical analysis of the literature does not furnish epidemiological arguments to recommend periodical mass radiography for bronchial carcinoma. However, because lungcancer forms an extremely important public health problem and because the scarcity of randomized; controlled studies in this field, the committee advises - from a scientific point of view - to perform such a study in one or preferably two regions in the Netherlands. A number of conditions are mentioned which such a study at least should meet. (Auth.)

    Full Text Available Abstract Background Airway narrowing associated with chronic asthma results in the transmission of injurious compressive forces to the bronchial epithelium and promotes the release of pro-inflammatory mediators and the denudation of the bronchial epithelium. While the individual effects of compression or denudation are well characterized, there is no data to elucidate how these cells respond to the application of mechanical compression in the presence of a compromised epithelial layer. Methods Accordingly, differentiated normal human bronchial epithelial cells were exposed to one of four conditions: 1 unperturbed control cells, 2 single scrape wound only, 3 static compression (6 hours of 30 cmH2O, and 4 6 hours of static compression after a scrape wound. Following treatment, wound closure rate was recorded, media was assayed for mediator content and the cytoskeletal network was fluorescently labeled. Results We found that mechanical compression and
