We describe a rare case of pedunculated endobronchial hemangioma observed in a 60 years old patient complaining of chronic productive cough and accessional dyspnea which had been progressively worsening over 20 years. The lesion was first noticed at fiberoptic bronchoscopy; then computed tomography scan was performed and integrated with tridimensional reconstruction techniques. Pathology showed the picture of a vascular neoplasm, compatible with capillary hemangioma. The lesion was submitted to laser-assisted endoscopic removal in order to relieve the obstruction, leading to remission of symptoms.

A 63-year-old woman experienced progressive respiratory distress and psoriatic plaques. The radiographic images showed diffuse interstitial infiltrates. The surgical open lung biopsy revealed an obliteration of the alveolar spaces by plugs of connective tissue distributed within the terminal bronchioles, alveolar ducts and spaces. No relevant cause was determined, and she was diagnosed with idiopathic organising pneumonia. The patient was discharged with oral glucocorticosteroid and supplemental oxygen therapy. One month later, the patient's pulmonary status had progressively worsened, and she was re-admitted. She required higher oxygen concentrations and mechanical ventilation. Pharmacological therapy included high-dose steroids and cyclophosphamide. Serological assays revealed high antibodies titers (both IgM and IgG) to cytomegalovirus. Therefore, ganciclovir was added to the regimen. Despite the therapy, she died as a result of the disease. The review of the current literature on the topic is also presented.

Acromegaly is an insidious disorder caused by a pituitary growth hormone (GH)-secreting adenoma resulting in high circulating levels of GH and insulin-like growth factor I (IGF-I). Respiratory disorders are common complications in acromegaly, and can severely impact on quality of life, eventually affecting mortality.

The assessment of the distribution of allergen skin test sensitizations is highly recommended for the optimal management of allergic respiratory conditions. We aimed at evaluating the distribution of allergen sensitizations in individuals with asthma and/or rhinitis in the Southern region of ltaly, and at exploring whether changes in the frequency of allergen sensitizations occurred after a 5-year period. Demographic data and skin prick test sensitizations to allergens from asthmatics and/or rhinitis attending the Division of Respiratory Diseases, University of Palermo, Italy in 2005 (Phase 1) and in 2010 (Phase 2) were extrapolated and retained for analysis. A total of 2033 allergic respiratory patients were included (1002 in Phase 1 and 1031 in Phase 2). In both investigations, the most prevalent allergen sensitization was towards Parietaria; however, a significant reduction in the rate of prevalence after 5 years was recorded (from 60% to 48% of skin test positive patients, p < 0.0001). Up to one out of two subjects showed sensitization to dust mites in both Phases. Interestingly, Cypress pollen sensitization almost doubled from Phase 1 (17%) to Phase 2 (29%; p < 0.0001). Overall, the mean number of skin test sensitizations for each patient increased from 2.7 +/- 1.6 in Phase 1 to 3.1 + 1.8 in Phase 2 (p < 0.0001). The present findings confirm the prevalent role of Parietaria sensitization in the allergic population of the Mediterranean area of Southern Italy, and document the increase of Cypress sensitization. These observations could contribute to a proper management of chronic allergic respiratory conditions in this region.

The mainstay of management in asthma is inhalation therapy at the target site, with direct delivery of the aerosolized drug into the airways to treat inflammation and relieve obstruction. Abundant evidence is available to support the concept that inflammatory and functional changes at the level of the most peripheral airways strongly contribute to the complexity and heterogeneous manifestations of asthma. It is now largely accepted that there is a wide range of clinical phenotypes of the disease, characterized primarily by small airways involvement. Thus, an appropriate diagnostic algorithm cannot exclude biological and functional assessment of the peripheral airways. Similarly, achievement of optimal control of the disease and appropriate management of specific phenotypes of asthma should be based on drugs (and delivery options) able to distribute uniformly along the bronchial tree and to reach the most peripheral airways. Products developed with the Modulite(®) technology platform have been demonstrated to meet these aims. Recent real-life studies have shown clearly that extra-fine fixed-combination inhaled therapy provides better asthma control than non-extra-fine formulations, thus translating the activity of the drugs into greater effectiveness in clinical practice. We suggest that in patients with incomplete asthma control despite good lung function, involvement of the peripheral airways should always be suspected. When this is the case, treatments targeting both the large and small airways should be used to improve asthma control. Above all, it is emphasized that patient adherence with prescribed medications can contribute to clinical success, and clinicians should always be aware of the role played by patients themselves in determining the success or failure of treatment.

Chronic obstructive pulmonary disease (COPD) and ageing may contribute to malnutrition. We aimed to explore whether COPD and ageing determine malnutrition in different manners. 460 stable COPD outpatients (376 males and 84 females) from the Extrapulmonary Consequences of COPD in the Elderly (ECCE) study database were investigated (age 75.0±5.9 yrs; forced expiratory volume in 1 s 54.7±18.3% predicted). Nutritional status was evaluated using the Mini Nutritional Assessment® (MNA) questionnaire. From the MNA, three scores exploring the domains of the nutritional status were calculated: body composition, energy intake and body functionality scores. Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages were negatively correlated with five MNA items exploring mobility, patient's perception of own nutrition and health status, and arm and calf circumferences (lowest Spearman's rho (rs)=-0.011; highest p=0.039). GOLD stages were independently correlated with body composition and body functionality scores (model r2=0.073). Age was negatively correlated with four MNA items exploring loss of appetite, fluid intake, mobility and autonomy in daily life (lowest rs=-0.013; highest p=0.030). Age was independently correlated with body functionality score (model r2=0.037). Severe COPD and ageing are independent and probably concurrent conditions leading to malnutrition. The MNA questionnaire allows a valuable insight into the complexity of components of nutritional status and may provide useful clues for treatment strategies.

Background and Aims. An ageing lung is characterised by distal airspace enlargement without alveolar wall destruction: therefore the anatomical distinction between senile lung and emphysema is clear-cut. In clinical settings the definition of precise boundaries between normalcy and pathology is more difficult with the risk of overdiagnosis. CT is an important diagnostic advancement in the field of COPD. Most methods for the evaluation of emphysema are based on the detection and measurement of areas characterised by a density level below a threshold assumed to characterize parenchymal destruction. Methods. Our retrospective study included 47 healthy subjects (65-91 years), 36 never smokers and 11 former smokers. As a reference sample we recruited 9 patients with emphysema (69-81 years). Thoracic scan was performed by single slice spiral CT and acquired without contrast enhancement. For each scan and on both lungs we sampled eighteen regions of interest in the upper, middle and lower field. Mean lung density (MLD) and lower limit of normal (LLN) of density distribution were calculated. Results. MLD for the whole study sample was -846±41 HU. -901 HU was the LLN of density distribution in the study sample. No significant correlation was noted between age and MLD. In the emphysematous sample the average lung density was -946±18 HU. The mean coefficient of variation was 3% in the healthy sample and 2% in the emphysematous one. The difference between groups was significant (p<0.0001). In one healthy subject only we measured a value slightly below the threshold reported in literature for conventional CT; no emphysematous value fell above the LLN. Conclusions. This study highlights the fact that in the elderly the threshold level of lung density commonly adopted in diagnostic algorithms of emphysema is fully applicable. When applying this method to older subjects the risk of misinterpreting areas of physiologic non-destructive reduction of density as emphysema is low.

The role of genetic and environmental factors, as well as their interaction, in the natural history of asthma, allergic rhinitis and chronic obstructive pulmonary disease (COPD) is largely unknown. This is mainly due to the lack of large-scale analytical epidemiological/genetic studies aimed at investigating these 3 respiratory conditions simultaneously. The GEIRD project is a collaborative initiative designed to collect information on biomarkers of inflammation and oxidative stress, individual and ecological exposures, diet, early-life factors, smoking habits, genetic traits and medication use in large and accurately defined series of asthma, allergic rhinitis and COPD phenotypes. It is a population-based multicase-control design, where cases and controls are identified through a 2-stage screening process (postal questionnaire and clinical examination) in pre-existing cohorts or new samples of subjects. It is aimed at elucidating the role that modifiable and genetic factors play in the occurrence, persistence, severity and control of inflammatory airway diseases, by way of the establishment of a historical multicentre standardized databank of phenotypes, contributed by and openly available to international epidemiologists. Researchers conducting population-based surveys with standardized methods may contribute to the public-domain case-control database, and use the resulting increased power to answer their own scientific questions.

BACKGROUND:Airway inflammation in asthma involves both large and small airways, and the combination of inhaled corticosteroids (ICS) and long acting beta-2 agonists (LABA) is the mainstay of therapy. Available inhaled combinations differ in terms of drug delivery to the lung and the ability to reach small airways.AIM:To evaluate whether treatment with an extra-fine inhaled combination provides additional effects vs a nonextra-fine combination on airway function.METHODS:After a 1- to 4-week run-in period, patients with asthma were randomized to a double blind, double dummy, 12-week treatment with either extra-fine beclomethasone/formoterol (BDP/F) 400/24 microg daily or fluticasone propionate/salmeterol (FP/S) 500/100 microg daily. Methacholine (Mch) bronchoprovocation challenge and single breath nitrogen (sbN2) test were performed.RESULTS:Thirty patients with asthma (15 men), mean age 43, mean forced expiratory volume in the first second (FEV(1)) 71.4% of predicted, were included. A significant increase (P < 0.01) versus baseline was observed in predose FEV(1) in both BDP/F and FP/S groups (0.37 +/- 0.13 l and 0.36 +/- 0.12 l, respectively). PD(20)FEV(1) Mch improved significantly from 90.42 (+/-30.08) microg to 432.41 (+/-122.71) microg in the BDP/F group (P = 0.01) but not in the FP/S group. A trend toward improvement vs baseline was observed for BDP/F in closing capacity (CC), whereas no differences were recorded in other sbN(2) test parameters.CONCLUSION:The findings of this pilot study suggest that an extra-fine inhaled combination for the treatment of asthma has beneficial effects on both large and small airways function as expressed by Mch and sbN(2) tests.

Although highly prevalent, asthma is under diagnosed and undertreated in the elderly. This is partly due to heterogeneous presentations. In particular, airway obstruction may modify its characteristics towards nonreversible features, possibly due to remodelling. Risk factors include age-related modifications affecting airway reactivity, atopy, tobacco smoking, environmental pollution and gastro-oesophageal reflux disease.Asthma in the elderly can be distinguished in terms of early or late onset, which identifies two distinctive patterns with clinical and therapeutic implications. The disease is associated with accelerated functional decline and increased risk of mortality. Clinical and functional characteristics of geriatric asthma may contribute to erroneous diagnosis of chronic obstructive pulmonary disease. However even long-standing asthma maintains a distinctive pathology.Comorbidities are frequent in such subjects and significantly influence their quality of life. In principle, treatment of asthma in the elderly does not differ from that of younger individuals; however, the response may be suboptimal. Bronchodilators are important but age-related impairment in responsiveness may limit their effectiveness. Inhaled anticholinergic drugs may represent a valid or adjunct alternative to beta(2)-agonists.A peculiar problem is the underuse of inhaled corticosteroids probably connected to the fear for untoward effects. Careful attention should be paid to the adherence to therapy, particularly in subjects with comorbidities submitted to complex treatments.

The definition of asthma has evolved from that of an episodic disease characterized by reversible airways constriction to a chronic inflammatory disease of the airways, with at least partially reversible airway constriction. Increasing evidence supports the notion that small and large airways play a central role in asthma pathophysiology with regard to inflammation, remodeling and symptoms. The contribution of the distal airways to the asthma phenotype carries implications for the delivery of inhaled medications to the appropriate areas of the lung and for the monitoring of the response to asthma treatment. Asthma control is evaluated on the basis of symptoms, lung function and exacerbations. However, evidence suggests that dissociation between lung function and respiratory symptoms, quality of life and airway inflammation exists. In this study, common spirometric parameters offer limited information with regard to the peripheral airways, and it is therefore necessary to move beyond FEV 1 . Several functional parameters and inflammatory markers, which are discussed in the present study, can be employed to evaluate distal lung function. In this study, extrafine formulations deliver inhaled drugs throughout the bronchial tree (both large and small airways) and are effective on parameters that directly or indirectly measure air trapping/airway closure.

Background: Forced expiratory volume in 6 s (FEV6) has been proposed as a more easily measurable parameter than forced vital capacity (FVC) to diagnose airway disease using spirometry. A study was undertaken to estimate FEV6 repeatability, to identify correlates of a good quality FEV6 measurement and of volumetric differences between FEV6 and FVC in elderly patients.Methods: 1531 subjects aged 65-100 years enrolled in the SA. R. A project (a cross-sectional multicentre noninterventional study) were examined. FEV6 was measured on volume-time curves that achieved satisfactory start-oftest and end-of-test criteria. Correlates of FEV6 achievement were assessed by logistic regression.Results: Valid FEV6 and FVC measurements were obtained in 82.9% and 56.9%, respectively, of spirometric tests with an acceptable start-of-test criterion. Female sex, older age, lower educational level, depression, cognitive impairment and lung restriction independently affected the achievement of FEV6 measurement. Good repeatability (difference between the best two values <150 ml) was found in 91.9% of tests for FEV6 and in 86% for FVC; the corresponding figures in patients with airway obstruction were 94% and 78.4%. Both FEV6 and FVC repeatability were affected by male sex and lower education. Male sex, airway obstruction and smoking habit were independently associated with greater volumetric differences between FEV6 and FVC.Conclusions: In elderly patients, FEV6 measurements are more easily achievable and more reproducible than FVC although 1/6 patients in this population were unable to achieve them.

The case of a 43-year-old woman with intralobar pulmonary sequestration, Pryce type one, is presented. The medical history was characterised by recurrent bronchopneumonia, productive cough with purulent sputum and hemoptysis in the last three years. Diagnosis was made by CT angiography: multiplanar, maximum intensity projection and volume rendering reconstructions were visualised. A volume reduction of middle and lower lobe with multiple cyst-like bronchiectasis was detected and no evident relationship with tracheobronchial tree was pointed out. Reconstructions aimed at evaluating bronchial structures demonstrated no patency of middle and lower lobar bronchi. The study carried out after contrast medium infusion in arterial phase showed a vascular disorder characterised by an accessory arterial branch arising from the upper portion of thoracic aorta which, after moving caudally to pulmonary hilus with a tortuous course, supplied the atelectatic parenchyma. No anomalous venous drainage was detected. The patient underwent surgery with resection of two pulmonary lobes. CT compares favourably with other alternative imaging technique for pulmonary sequestration as multiplanar reconstructions allow not only the detection of supplying vessel, but also the accurate description of heterogeneous characteristics of the mass and adjacent structures. Finally an imaging-based diagnostic algorhythm is proposed.
