A double blind vs placebo study was carried out to study the effect of letosteine on the symptoms and clinical course of paediatric patients suffering from acute febrile bronchitis. Forty children were recruited for the research: 20 were treated with letosteine in a dose of 25 mg x 3 g/die and 20 with placebo; treatment lasted 10 days. The following parameters were assessed during the trial: body temperature, cough, thoracic objectivity, respiratory function indices. The results of the study show that in the letosteine treated group there is a statistically significant decrease in fever, a favourable evolution of thoracic objectivity and an improvement in certain respiratory function parameters (MEF 75, PEF). It is concluded that treatment with letosteine leads to a significant increase in the rate of regression of thoracic symptomatology and a faster, more substantial reduction in fever in children suffering from acute bronchitis. This is probably the result of drug action on mucus viscosity, restoring optimal mucociliary clearance, and through action fostering the penetration of antibacterial substances into the mucus.

It was intended to investigate the influence of environmental factors with regard to the long-term effect of air pollution by means of pulmonary function. 3,482 pupils from places of different environmental loading were examined by screening with flow-volume. According to the emission values to SO2 and dust especially the MEF 50 and MEF 25 values showed well correlating restraints. Cough, dyspnea and passive smoking could be well coordinated. Beyond the objectivation of the significance of the environmental situation the recommendation may be deduced to do such investigation in the frame of an enlarged school medical programme for detecting patients with bronchopulmonary risk.

Spirometry is indicated in all the children with clinical diagnosis of asthma, chronic/recurrent cough or wheeze, exercise induced cough or breathlessness and with recurrent respiratory manifestations. Mid expiratory How 25-75% (MEF 25-75) is an important diagnostic parameters in children due to its effort independence, high sensitivity in bronchodilator reversibility test and also because it represents smaller airways and is likely to be affected in mildest obstruction. The base line spirometry, bronchodilator reversibility and histamine challenge are diagnostic of hyper reactive airway with 98% sensitivity. Flow volume loops hardly add to the diagnosis and also need more co-operation from the subject. Therefore it is not useful in children. PEFR monitoring constitutes an important part of the followup care of asthma patients.

Fifty newly diagnosed nonsmoker patients suffering from mild to moderate hypertension (diastolic BP 90 to 114 mmHg), randomly selected and not having respiratory or other systemic diseases which may affect pulmonary functions were subjected to thorough interrogation and clinical examination. Twenty five normal age and sex matched healthy volunteers served as control. All patients and controls were subjected to ventilatory pulmonary function tests (VPFT), done by computerized spirometer. Hypertensive patients were put on oral enalapril, doses were titrated and maintained on 2.5 to 10 mg once daily. Twenty percent of the total hypertensive patients reported mild to moderate dry cough and was more frequently observed among females (27%). Significant decline was observed in MEF 50% and MEF 25% of vital capacity values (p 0.0204 and 0.0001) after 10 days of enalapril therapy. These two VPFT parameters showed significantly higher decline among patients who developed cough as compared to patients who did not develop cough. Decline in VPFT parameters were directly related to doses of enalapril.

The present study focused on patients with cystic fibrosis (CF), who were on maintenance therapy with recombinant human deoxyribonuclease (rhDNase), with the aim of comparing efficacy and possible side effects of nebulisation of rhDNase when taken before bedtime with efficacy and side effects when taken after waking up. A randomised, double-blind, double-dummy, crossover study group was used. The inclusion criteria were as follows: 1) CF, 2) stable clinical condition and 3) rhDNase maintenance therapy. Patients in group I inhaled rhDNase before bedtime and a placebo after waking up in weeks 1-2. The protocol was reversed during weeks 3-4. Group II patients performed the reverse of this sequence. Patients continued with their daily routine sputum expectoration. The primary end-point was classified as the maximal instantaneous forced flow when 25% of the forced vital capacity remained to be exhaled (MEF(25%)). Pulmonary functions tests were performed on days 0, 7, 14, 21 and 28. At 1, 2, 3 and 4 weeks arterial oxygen saturation and cough frequency were measured during the night. A total of 24 patients completed the study. The mean (range) age of the patients was 13 (6-19) yrs. MEF(25%), taken to be the primary end-point, did not show a significant difference between nebulisation of rhDNase before bedtime compared with when taken after waking up. Nocturnal cough, oxygen saturation, and other secondary end-points were not significantly different between the two study periods. In conclusion, the present study found that it is equally effective and safe to nebulise recombinant human deoxyribonuclease before bedtime compared with when performed after waking up in children with cystic fibrosis, who are on maintenance treatment with recombinant human deoxyribonuclease.

Patients who have chronic obstructive pulmonary disease (COPD) and bronchial asthma (BA) share symptoms such as, dyspnoea, cough and wheeze. Differentiating these diseases in the ambulatory setting can be challenging especially in older adult smokers who are being treated with a variety of medications. The objective of this study was to test the value of adding a maximal inspiratory manoeuvre to basic spirometry to differentiate COPD and BA. One hundred forty-three COPD patients and 142 BA patients had measurements of maximal inspiratory and expiratory flow during routine spirometry. Parameters from these tests were used to assess diagnostic accuracy using receiver-operating characteristic (ROC) analyses followed by logistic regression. The association of two independent parameters were analyzed using linear regression analyses. Results show that forced expiratory volume in one second/forced vital capacity (FEV1/FVC%) <62.4 was the best independent predictor to diagnose COPD. The combination of FEV1/FVC% <62.4 and the ratio of peak inspiratory flow/maximal expiratory flow at 50% FVC (PIF/MEF50) >3.06 significantly predicted COPD. Post-test probability for prediction of COPD was 82.0% when patients had both parameters. When asthmatic patients with a smoking history were compared with COPD patients, FEV1/FVC% <63.4 and PIF/MEF50 >3.29 were both independent predictors of COPD. The post-test probability for COPD was 94.4% when patients had both parameters. The association between FEV1/FVC% and PIF/MEF50 was significantly different between COPD and BA. In conclusion, the addition of the maximal inspiratory effort to routine pulmonary function measurements provides a simple test to help differentiate COPD and BA.
