Adhesion molecules play an important role in inflammatory processes and influence on recruitment of effector cells. The aim of our study was to assess the percentage of T-lymphocytes expressing LFA-1, Mac-1 and ICAM-1 in bronchoalveolar fluid (BALF) and blood of patients with sarcoidosis, atopic bronchial asthma and chronic bronchitis. The reference group consisted of patients with haemoptysis or suspected of having bronchial carcinoma. Expression of adhesion molecules was revealed by /APAAP/ alkaline phosphatase anti alkaline phosphatase method. The highest percentage of lymphocytes expressing all adhesions molecules in BALF and blood was observed in patients with chronic bronchitis. Reductions of T-cells in BALF of patients with bronchial asthma and sarcoidosis may reflect of their direct binding in inflammatory sites. This studies confirm the involvement of adhesion molecules in maintenance of chronic inflammatory processes in the respiratory tract.

The incidence of bronchiectasis (BCT) has probably decreased in developed countries in recent years, but reliable statistical data on its occurrence are still lacking. The aim of the present study was to retrospectively evaluate the prevalence, age distribution and aetiology of BCT, diagnosed in a selected series of symptomatic patients of a Western country by using bronchography. The authors analysed the main known predisposing and associated conditions (PACs), and the occurrence and age distribution of BCT in 144 consecutive patients who underwent bronchological examination (fibreoptic bronchoscopy and bronchography) in the years 1987-1994 because of recurrent purulent bronchitis and/or haemoptysis. The overall prevalence of BCT was 34% (49/144); its age distribution was: 17.2% (0-10 yrs), 43.7% (11-20 yrs), 38% (21-30 yrs), 37.5% (31-40 yrs), 33.3% (41-50 yrs), 40% (51-60 yrs), and 20% (61-70 yrs). Thirty-one PACs were found in 29/144 patients of the whole study group. The prevalence of BCT was significantly higher in the subgroup of 29 patients with PACs than in the subgroup of 115 patients without PACs (75.9% versus 23.5%; p < 0000001). The aetiology of BCT was mainly unexplained, as it was only possible to detect 24 PACs in 22/49 patients with BCT (44.9%): congenital, genetic and immune disorders (eight), localized airways obstructive diseases (five), pulmonary infections (three), bronchial asthma (two), pulmonary lobar fibrosis (two), ulcerative colitis (two), dermatomiositis (one), and toxin inhalation (one). The authors conclude that bronchiectasis still occurs in a large percentage of symptomatic patients of a developed country in the post-antimicrobial era, especially in the second to sixth decades, as well as in the presence of predisposing and associated conditions; its aetiology remains unknown in more than half of cases.

Churg-Strauss syndrome (CSS) (allergic granulomatosis and angitis) is an uncommon form of systemic vasculitis, which is rare in children. It is characterized by peripheral blood hypereosinophilia, systemic necrotizing vasculitis, and a preceding history of bronchial asthma. We described a boy with initial presentation of poorly controlled bronchial asthma, allergic rhinitis, recurrent sinusitis and several episodes of hemoptysis since the age of 9. He then developed purpuric skin lesions, generalized soreness, and symptoms of mononeuritis multiplex at age 11. On admission to our hospital at the age of 12, he developed marked pericardial effusion. After a series of studies including chest computed tomography (CT), skin biopsy, nerve conduction study, and serological tests for autoantibodies, CSS was diagnosed. Thereafter, he received regular corticosteroid therapy, and his symptoms were generally well-controlled with occasional acute exacerbation. The clinical characteristics, diagnosis and management of CSS in children are also reviewed.

The European Epidemiologic Registry of Cystic Fibrosis began collecting longitudinal data on European cystic fibrosis patients in 1994. A cross-sectional analysis was performed to identify the factors associated with low values of % predicted forced expiratory volume in one second (FEV1) upon patient enrollment. Data from 7,010 patients aged > or =6 yrs were included. Clinical conditions, microbiological isolates and medications reported at enrollment or within the following 180 days were analysed for age-specific associations. Factors associated with FEV1 that were lower by >10% of pred values were: lower weight for age percentiles, haemoptysis, pneumothorax, pulmonary symptoms at presentation, Pseudomonas aeruginosa, Burkholderia cepacia, oral corticosteroids, nonsteroid anti-inflammatory drugs, dornase alfa, oxygen and assisted ventilation and, in patients >12 yrs old only, use of airway clearance techniques, inhaled bronchodilators, oral nutritional supplements, pancreatic enzymes and insulin or oral hypoglycaemics. Slightly impaired lung function (5-10%) was associated with: diabetes (> or = 18-yrs-old), gastro-oesophageal reflux, allergic bronchopulmonary aspergillosis, asthma-like symptoms, portal hypertension, Aspergillus spp. and Candida spp. Sex, Haemophilus influenzae and Staphylococcus aureus were not associated with impaired pulmonary status. Regular exercise (especially in older patients) and nasal polyposis were associated with slightly better FEV1. The results confirm those of previous studies and suggest selective prescribing in sicker patients.

Aspergillus species are ubiquitous in the environment and are inevitably inhaled into the airways. Inhalation of Aspergillus conidia or mycelium fragments may result in colonisation of the airways. In susceptible hosts colonisation may subsequently cause disease. Patients with pre-existent cavities may develop aspergillomas which may be quiescent or cause symptoms especially recurrent haemoptysis. Acute invasive disease is potentially lethal in patients who are vulnerable to infection due to underlying lung diseases or immunosuppression. In addition to its ability to colonise the human respiratory tract, Aspergillus has a significant potential to act as a powerful allergen resulting in Aspergillus asthma and allergic bronchopulmonary aspergillosis. The various presentations of pulmonary disease caused by Aspergillus are reviewed here, focusing primarily on clinical aspects rather than basic science.

Cases of childhood hemoptysis are rare and usually result from foreign body aspiration or congenital heart or lung diseases. However, human hirudiniasis due to the leech still exists, and could involve the upper airways after drinking infested water from quiet streams and pools. We report the case of a 6-year-old child who presented suffocating at the emergency room after having been misdiagnosed and treated for asthma over a 1-month period. His mother reported he had had recurrent hemoptysis, as well. The child inadvertently drank leech-infested water in a rural area of northern Syria. Surgical removal of the leech resulted in prompt resolution of the symptoms. Although laryngeal hirudiniasis is rare in the developed world, it remains a possible cause of childhood airway obstruction, hemoptysis, and anemia which needs to be considered in patients with a suggestive history.

Combining helical volumetric CT acquisition and thin-slice thickness during breath hold provides an accurate assessment of both focal and diffuse airway diseases. With multiple detector rows, compared with single-slice helical CT, multislice CT can cover a greater volume, during a simple breath hold, and with better longitudinal and in-plane spatial resolution and improved temporal resolution. The result in data set allows the generation of superior multiplanar and 3D images of the airways, including those obtained from techniques developed specifically for airway imaging, such as virtual bronchography and virtual bronchoscopy. Complementary CT evaluation at suspended or continuous full expiration is mandatory to detect air trapping that is a key finding for depicting an obstruction on the small airways. Indications for CT evaluation of the airways include: (a) detection of endobronchial lesions in patients with an unexplained hemoptysis; (b) evaluation of extent of tracheobronchial stenosis for planning treatment and follow-up; (c) detection of congenital airway anomalies revealed by hemoptysis or recurrent infection; (d) detection of postinfectious or postoperative airway fistula or dehiscence; and (e) diagnosis and assessment of extent of bronchiectasis and small airway disease. Improvement in image analysis technique and the use of spirometrically control of lung volume acquisition have made possible accurate and reproducible quantitative assessment of airway wall and lumen areas and lung density. This contributes to better insights in physiopathology of obstructive lung disease, particularly in chronic obstructive pulmonary disease and asthma.

A rare case of primary pulmonary neoplasm is reported. The patient was a 38-year-old woman presenting with obstructive pneumonia. Fiberoptic bronchoscopy revealed an endobronchial mass obstructing the left main bronchus: a reddish polypoid mass which bled on contract that was suggestive of bronchial adenoma. The patient also had a long-standing history of bronchial asthma and hemoptysis and the delay in establishing the eventured diagnosis was caused by the minor symptoms mimicking those of asthma. A persistent restrictive lung and the presentation of obstructive pneumonia were important clues which warranted further investigation by computed tomography (CT) scan and bronchoscopy. The patient underwent rigid bronchoscopy with CO2-laser ablation under general anesthesia. Histopathology confirmed a bronchial adenoma. The clinical response was excellent. Bronchial adenoma should be considered in young patients presenting with asthma, hemoptysis and obstructive pneumonia. Bronchoscopic CO2-laser ablation is an effective treatment and provides an alternative to aggressive thoracotomy.

A 29-year-old woman at 37 weeks of gestation was brought to our hospital as an emergency patient complaining of severe cough, hemoptysis and dyspnea. On arrival, we suspected that she was suffering from bronchial asthma or pulmonary embolism, but were unable to improve her respiratory condition. The decision was made to terminate gestation immediately and an emergency cesarean section was performed under spinal anesthesia. Postoperatively diagnosis of tuberculosis was made. Fortunately, there was no intramural tuberculous infection. She was a nurse. Nurses are twice as likely as the general public to contract tuberculosis. Medical workers must keep in mind that they may be infected with tuberculosis and they could also become the source of infection of tuberculosis. It is important to rule out tuberculosis when a patient, particularly a medical worker, complains of severe cough, hemoptysis and dyspnea.

Aspergilli are widely distributed in nature and there is abundant opportunity to acquire infection. The fungus is usually only locally invasive in healthy tissues. Its culture from sputum on one occasion may have no significance. Its growth in the bronchial tree of asthmatics may produce sensitization with aggravation of the asthma and bronchial plugging. Multiplication in dead or damaged lung tissue such as infarcts is not uncommon. The fungus may also colonize pre-existing lung cavities, especially those remaining after treatment of tuberculosis. The ball of fungus produces a characteristic radiological picture, particularly on tomograms, which is usually sufficient to make the diagnosis. Hemoptysis is common. Inaction may be preferable to excision, especially in a patient with impaired lung function. Seven cases have been described to illustrate some of the features and natural history of the condition. The mounting number of sterile cavities left in lungs has increased the number of mycetomas which have developed.
