Health promotion can contribute towards reducing inequality and ensuring equal opportunities, providing the means to enable the entire population to develop its maximum health possibilities. Women living in areas with social transformation needs (ASTN) are an especially vulnerable group due to the situation of material deprivation and social exclusion in which they live. Health promotion programmes for this group can bring about an improvement in their health. This paper describes the health promotion programme Socio-educational Groups of Primary Care for Women (SEGPC-W), and evaluates its implementation in ASTN in the city of Seville (Spain), as well as the benefits and difficulties of its development through a documentary analysis and interviews with participating professionals., (Copyright © 2017 SESPAS.

Objective: To evaluate bronchial hyperresponsiveness in children under 4 years of age with recurrent wheezing bronchitis, and to determine if its presence or absence can predict the subsequent progression to a transient or persistent wheezing bronchitis phenotype., Population and Methods: A bronchial challenge test was performed with methacholine using a modified tidal volume method, without sedation in a group of patients from 8 to 47 months of age with recurrent wheezing bronchitis and a control group of healthy children. A decrease in oxygen saturation of ≥ 5% or an increase in respiration rate of >50% [PCwheeze (PCw)] was considered a positive response. The patients were subsequently clinically followed up to assess their progress., Results: A total of 63 patients and 16 controls were studied (mean age 23.9 vs. 25.2 months). The PCw was lower than the control group (≤ 4 mg/ml) in 43 (68%) children from the bronchitis group (P<0.001). No significant adverse effects were observed on performing the test. After a mean follow up of 28.5 months, completed in 49 of the patients, no differences were seen between the presence of bronchial hyperresponsiveness at the beginning of the study and the subsequent progression to transient, infrequent and frequent wheezing (P=0.63)., Conclusions: A high percentage of children under 4 years of age affected by wheezing bronchitis had a bronchial hyperresponse. The subsequent progression to transient or persistent wheezing bronchitis phenotype is not associated with bronchial hyperresponsiveness., (Copyright © 2010 SEPAR. Published by Elsevier Espana.

Background: The objective of the study was to assess bronchial inflammation in preschool children with recurrent bronchitis by measuring exhaled nitric oxide., Patients and Methods: The study included patients under 4 years of age with at least 3 episodes of wheezing in the past year (n=63) and a control group (n=30). Exhaled nitric oxide was measured in samples collected offline during spontaneous tidal breathing with a face mask and stored in Mylar balloons., Results: The fractional exhaled nitric oxide concentration (FE(NO)) was higher in the group with bronchitis (mean [SD], 5.3 [1.3] parts per billion [ppb]) than in the control group (4.6 [1.1]ppb) (P=.02). There was a significant difference between the control group and children in the bronchitis group not treated with inhaled corticosteroids (P<.05), but not between controls and corticosteroid-treated patients. A relationship with eosinophil count was observed in that those with higher counts (>400 microL) had higher FE(NO) levels (P<.01). No relationship was observed between FE(NO) and a positive methacholine challenge test. Follow-up lasted at least 20 months. The initial FE(NO) level did not differ significantly according to whether patients were subsequently transient, infrequent, or frequent wheezers (5.2 [0.98]ppb, 5.6 [1.5]ppb, and 4.8 [1.34]ppb, respectively; P=.36)., Conclusions: In children under 4 years of age with recurrent wheezing bronchitis who were asymptomatic at study entry, a small increase in FE(NO) was observed although there was a good deal of overlap with the control group.

This article is an academic review of the application in children of the measurement of fractional exhaled nitric oxide (FENO). We outline the joint American Thoracic Society/European Respiratory Society recommendations for online measurement of FENO in both cooperating children and children unable to cooperate, offline measurement with uncontrolled exhalation flow rate, offline measurement with controlled exhalation flow rate using a dynamic flow restrictor, and offline measurement during tidal breathing in children unable to cooperate. This is followed by a review of the normal range of values for single-breath online measurements obtained with a chemiluminescence FENO analyzer (geometric mean, 9.7 parts per billion [ppb]; upper limit of the 95% confidence interval, 25.2 ppb). FENO values above 17 ppb have a sensitivity of 81% and a specificity of 80% for predicting asthma of an eosinophilic phenotype. We discuss the response of FENO values to anti-inflammatory treatment and the use of this marker in the management of asthma. Results obtained with chemiluminescence and portable electrochemical analyzers are compared. The portable devices offer the possibility--in children over 5 years of age--of accurate and universal monitoring of exhaled nitric oxide concentrations, an emerging marker of eosinophilic inflammation in asthma that facilitates diagnosis, monitoring of disease progression, and assessment of response to therapy.

Objective: To assess the safety of the tracheal auscultation method for measuring bronchial hyperresponsiveness in healthy unsedated children aged less than 4 years and to establish a range of normal bronchial hyperresponsiveness values., Population and Methods: The study population consisted of healthy children aged between 6 months and 4 years. A methacholine bronchial provocation test was administered to unsedated children, using the tidal volume breathing technique and applying an abbreviated protocol. The test was considered positive when wheezing was heard in the trachea, arterial oxygen saturation (SaO2) fell by 5% or more, or respiratory rate increased by 50% or more., Results: A total of 16 children were studied. Ages ranged from 8 to 47 months, with a mean (SD) of 23.5 (12.2) months. There was no response to the methacholine in 11 children. In the other 5 children, there was a positive response at a concentration of 8 mg/mL. Response to the test was considered positive on the basis of tracheal wheezing in 3 cases, tracheal wheezing and a fall in SaO2 in 1 case, and a fall of SaO2 of 5% or more in 1 case. SaO2 never fell below 93%., Conclusions: As a means for assessing bronchial hyperresponsiveness, the tracheal auscultation method is appropriate, is simple to apply, and can be safely administered to unsedated children aged less than 4 years. The lowest concentration at which a response to methacholine occurs in healthy children of this age group is 8 mg/mL.

Very frequently we have to deal with children who follow specific treatment to combat their repetitive episodes of breathing difficulty and wheezing. In many cases, they suffer from asthma. Hippocrates defined asthma as "the condition which causes an excessive narrowing of the bronchi after a reaction with a provocative stimulus which usually does not produce any effect".

Mesalazine is an aminosalicillic derivative considered as a safe alternative to the relative frequency (5-55%) of adverse effects observed with sulfasalazine. The well known hepatoxicity associated with sulfasalazine and attributed to its sulfamidic fraction is limited to few cases described in the treatment with mesalazine. We herein present a new case of hepatoxicity by mesalazine in a patient with lymphocytic colitis. The possible pathogenic mechanism is also commented upon.

Objective: Our aim was to study the concentration of nitric oxide in the exhaled (ENO) and nasal (NNO) air of normal children and asthmatic children who are clinically and functionally stable., Patients and Methods: Using a nitric oxide chemiluminescence analyze and a register for CO2, pressure and flow, we studied 73 schoolchildren (6-17 years of age). This included 37 controls and 36 asthmatic children, 21 with mild asthma without antiinflammatory treatment and 15 treated with inhaled corticosteroids. We used the technique of slow exhalation against resistance for (ENO) determination and aspiration with stable flow in nasal cavity while holding the breath for (NNO) determination., Results: The mean ENO was 3.1 ppb (1-6) in the control group, 8.3 ppb (1.7-29.3) in the mild asthma group and 7.7 ppb (2-18.3) in the asthmatics treated with corticosteroids. There were significant differences (p = 0.0001) between the controls and both asthmatic groups. The mean NNO in the controls was 898 ppb and differences between this group and the asthmatic children were found. The ENO and NNO did not change in relation to age or sex. We did not find any relationship between ENO and lung function. There is a significant correlation between ENO and NNO in both asthmatic groups, but not in the control group., Conclusions: The ENO was higher in asthmatics than in control children. The slow exhalation against resistance technique prevents the contamination of exhaled air with nasal air and this technique can be applied to children over 6 years of age. The NNO was similar in the asthmatic groups and the control group.

Objective: This study examines the technical characteristics of two different peak expiratory flow meters, of high range, and the reference values of peak expiratory flow (PEF) for schoolchildren., Patients and Methods: The gauge accuracy and precision were previously determined in 20 units of each model (PF-Control and Mini-Wright), with a syringe servocontrolled by simulating 4 predetermined PEF fluxes (125, 262, 424 and 587 L/min). Relatives were asked about passive smoking and the childhood background concerning asthma, recurrent bronchitis or recent respiratory infection. The PEF of 1,142 schoolchildren, 669 boys and 473 girls between 6 and 16 years of age and coming from 6 different locations of different demographic and social characteristic of Catalonia, Spain, were measured., Results: Readings of both gauges differed in accuracy, although they presented a good intradevice precision. The PF-control is within the reliance intervals for fluxes of 425 and 587 L/min, with a suprareading of 15.3% for the 262 L/min and infrareading of 19.2% for the 125 L/min controls. Flux with the Mini-Wright shows systematic over-reading of between 17.9% and 30.2%, with an accurate reading only in the 587 L/min control flux. No significant correlation was found between the PEF and family passive smoking (56.3%), pupils with asthma background (7.1%), recurrent bronchitis (11%) or recent respiratory infection (7.7%)., Conclusions: The accuracy difference forces the use of diverse percentile tables for each of the PEF gauge patterns; hence, we present the reference tables for each gauge, in means of 10, 50 and 90 percentiles, which can be used as reference values for our school population according to their age, size and sex.

Objective: A prospective study to assess the incidence of mycobacterial infection in patients with cystic fibrosis in our geographical area was performed., Patients and Methods: A monitored follow-up was carried out in 91 patients over a period of 20 months, during which time 522 respiratory samples were obtained. These were processed by standard techniques of decontamination with sodiumlaurylsulphate, cultured on Löwenstein-Jensen medium and identified by biochemical and cultural characteristics and hybridization by specific probes. At the same time, the clinical reports of the patients with positive culture were reviewed., Results: Positive cultures of mycobacteria were obtained from 4 patients. Environmental mycobacteria were isolated in three of them (M. xenopi, M. fortuitum and M. avium) and M. chelonei and later M. tuberculosis in the forth. None of the isolations of environmental mycobacteria were associated with deterioration of pulmonary function, while the isolation of M. tuberculosis in one of the patients coincided with an episode of decompensation in respiratory function. None of the patients presented sensitivity of the tuberculin skin test., Conclusions: It is advisable to investigate the mycobacteria in the presence of exacerbation of the respiratory process, above all taking into account the high incidence of tuberculosis in our geographical area. The isolation of environmental mycobacteria was not associated with pulmonary deterioration, but they represent a potential danger as opportunist pathogens, affecting patients of which many are candidates for lung transplants.

Objective: To study the microbiology of cystic fibrosis in our hospital for the period from 1985 to 1992., Material and Methods: The number of samples analyzed totalled 1,034, most of which were sputum and nasopharyngeal aspirates belonging to 113 patients (49 women and 64 men). The average age was 10 years (range: 15 days-33 years)., Results and Discussion: Only 1.7% of the samples were negative. Normal flora were found in 10.8% and one or more potentially pathogenic microorganisms were found in the remaining 87.4%. Colonies were over 10(6) UFC/ml in size in 77.8% of the quantified cultures. The most frequently identified microorganisms in the population overall were P. aeruginosa (53.9%), S. aureus (30.3%) and H. influenzae (22.0%). In patients less than 12 months old, however, the most common isolations were of S. pneumoniae and B. catarrhalis; cultures from patients older than 16 years old most often yielded filiform fungi, mainly Aspergillus spp. We found no strains of Legionella spp. and P. cepacia was found in only 3 cases, in which the clinical outcome was good. In addition to the 3 most common organisms, we recorded several consecutive isolations of Proteus mirabilis, Xanthomonas maltophilia and Serratia marcescens in patients older than 11 years old; this finding suggests that given the improved survival of cystic fibrosis patients over the coming years and the antibiotic pressure placed on them, there may be slight changes in the bacterial ecology typical of this disease. No strain of S. aureus proved resistant to methicillin, but P. aeruginosa was shown to be resistant to gentamycin (58.2%) among the aminoglycosides and also to some of the beta-lactams considered to be effective, as follows: 25.2% to piperacillin, 22.6% to ceftazidime and even 19.8% to aztreonam. There was slight resistance of ciprofloxacin (6.3%).

We present our experience of 26 cases of cystic adenomatoid malformations of the lung (CAM), treated in the Department of Pediatric Surgery in our hospital between 1967-1991. There were two clinical pictures: one neonatal severe respiratory distress and successive repeated pulmonary infection appearing after the patient's first year of life and requiring both urgent diagnosis and treatment. Embryological development determines the pathologic classification of this entity in 3 types. Basic examinations by image are analyzed, bearing in mind their diagnostic value and the patterns they show. After analysing all the conditioning factors, no explanation has been found to the different course that this affectation (< 1 month and > 1 year of age respectively). Normally, neonatal mortality is closely related to other malformations, particularly to cardiovascular ones. Differential diagnosis is very important in the neonatal period, especially with regard to diaphragmatic hernia, lobar emphysema and pulmonary cysts. All these cases have been verified and classified by means of a pathologic study, which has shown the need for surgical operation. In the follow up of the patients no alteration has been noticed in the pulmonary function.

We present our experience of 38 patients suffering from congenital lobar emphysema (CLE) treated in the Department of Pediatric Surgery in our hospital between 1966-1991. 22 of these patients had to undergo surgical correction due to the severity of their respiratory symptoms. The other 16 presented mild respiratory symptoms: 8 of them received conservative treatment and the remainin 8 had to be operated on due to broncial compression caused by the vascular malformation. In most cases the main symptoms were dyspnea and cyanosis, which indicate the severity of the process. 20 cases presented during the patient's first month of life, 10 within the first 6 months and the remaining 8 between the first 6 months and 5 years. The different aetiologics forms in our study are analysed and compared with those described in the literature. The main diagnostic tested and revied, specially radiology tested led to a correct differential diagnosis and subsequently to an adequate therapeutic treatment. It is possible to carry out other tests since they do not actually help diagnosis, we have considered them unnecessary. All the surgical operations used are analysed as well as the complications observed. The clinical course of the patients has proved to be particularly good, since there was no mortality and the morbility rate was low.

We discuss the measures used, including physical examination, radiology, scintigraphy, T.A.C. and bronchography, to diagnoses 34 patients with bronchiectasis. In addition, the treatment used up until the time where the decision to perform surgery is also presented. Ten patients were submitted to surgical intervention and their operations, as well as the effected lobes, are described. The guidelines for surgical preparation, surgical difficulties encountered, postoperative care and the results of the surgeries are all discussed. Due to the age of some of these patients, obvious difficulties prevented functional testing. In those patients in whom it was possible, no loss in respiratory capacity has been observed.

The appearance of a clinical infectious disease in the lung is determined by the success or failure of pulmonary defense mechanisms. This review highlights several components of the normal respiratory host defenses: the mechanical barriers, the immunoglobulins IgG and IgA, and the interaction of the alveolar macrophages and lymphocytes. For optimal clearance, not only must effectors cells, responder cells, and mediators be present, but their action must be integrated.

Pulmonary sequestration is a congenital anomaly in which an aberrant systemic artery arising from the thoracic or abdominal aorta supplies part of the lung, usually the lower lobes. The sequestrates part of the lung may be anatomically included in the substance of the lobe (intralobar) or may be separate from the other lobes, being contained within its own pleural investment (extralobar). The cases of ten patients with sequestration of the lung seen during a seven-year period are reviewed, with special consideration of their clinical and radiographic findings. Emphasis is made on the differences of our cases with those of the literature: 1) Eighty per cent of the patients had previous symptoms; 2) The intra/extralobar ratio was 1.5/1; 3) All intralobar sequestrations were indifferently localized in left or right lower lobes, and 4) Associated anomalies were present with the same incidence in the two classic forms.

A case of hypersensitivity pneumonitis due to pigeon-dropping antigens is reported in a 9 year old girl, and compared with other seven previous reports in children. The insidious nature of this disease, as well as the importance of detailed environmental information in children with unexplained respiratory disease are emphasized. In this case, lung function tests showed a classic restrictive ventilatory defect, and a serious obstructive ventilatory defect evidenced in the narrowing of the smaller airways, and a reduction in the forced expiratory flow at small lung volumes. Hypersensitivity pneumonitis is a lung disease that results from sensitization by inhalation of a variety of organic dusts. Patients usually have circulating antibodies against the etiologic agents. Most patients with this disease also have sensitized T-cells to these agents. Long-term exposure can lead to irreversible lung disease. The histopathologic features are chronic interstitial and alveolar inflammation frequently accompanied by a granulomatous response. The most common symptomatic features are fever, chills and dyspnea 4 to 8 hours after exposure. Antibody activity to antigens is detected in the serum of both symptomatic and asymptomatic breeder's lung. Cellular hypersensitivity to antigens is demonstrated "in vitro" with peripheral lymphocyte populations in almost all symptomatic patients.

Four cases of congenital cystic adenomatoid malformation are presented. The age of the patients ranged from 1 day to 7 years. All cases were treated surgically and 3 of them survived. The only death in the group corresponded to the neonatal case. The clinical, radiological and patological features of congenital cystic adenomatoid malformation are also reviewed. Occasionally the clinical manifestations will be hardly noticeable or non existent and the malformation may be diagnosed beyond the neonatal period in the course of a radiological examination performed as routine or because of repeated respiratory infections. Surgery is the treatment of choice. In the group of neonates where the cystic adenomatoid malformation doesn't cause respiratory difficulty the authors feel that it might be advisable to postpone surgery until a later date.

The author exposes the diagnostic methodology to be followed with a patient showing recurrent pneumonias. Three phases of study are established, using more and more complex techniques and discussing the different possibilities of diagnosis in each phase and for each technique.
