In the early stages of bronchial asthma, it is frequent to find subjects with a positive history and an FEV1 or FEV1/FVC > 80% of the predicted value. This study investigated if the test of reversibility showed a reversible airway obstruction (RAO) in 291 subjects with the above clinical and functional features. Forced expiratory volume in 1 sec....

 Background: The protective effect of Ipratropium Bromide (IB) in the methacholine-induced bronchospasm is well known from some time. The objective of the present study was to assess whether a pretreatment with IB may influence the subsequent phase of methacholine-induced bronchospasm relief. Methods: Sixteen patients with bronchial hyper-reac....

Bronchial hyperresponsiveness (BHR) is a common feature in the majority of asthmatic subjects and methacholine is the most frequently used agent for the test. The influence of 3 or 5 min time intervals between doses steps in a double methacholine challenge test (MCH-3' or MCH-5') was investigated. Using the MCH-3' challenge, 52 intermittent asthmat....

Background and aim of the work: Pulmonary alveolar microlithiasis (PAM) is a rare disease characterized by intra-alveolar calcium deposits. The etiology of the disease is still unknown and many authors have supposed that an inherited local enzymatic defect is responsible for calcium deposition. The present paper aimed to study the disorder througho....

 Legionella pneumophyla is the agent responsible of Legionnaire's disease. It appears as a severe pneumonia and often requires admission in Intensive Care Unit. In literature, renal failure is reported to occur in 15 percent of Legionnaire disease and this event induce a mortality over 50% of these cases. The authors describe a case of Legionn....

 Changes in monocyte functions have been described in several human malignancies. The monocyte/macrophage system is known to play a crucial role in the rejection of tumor cells and phagocytosis represents an important defense mechanism used by these cells. This paper reports the adherence power and phagocyting ability (latex beads) of circulat....

Chemotherapy regimens based on platinum represent the reference standards in Non-Small Cell Lung Cancer (NSCLC) and when it is associated with radiotherapy and/or surgery (combined treatment) it improves survival of patients. Aim of this study was to estimate the efficacy of chemotherapy, based on high-dose epirubicin plus cisplatin, associated wit....

Chronic obstructive pulmonary (COPD) patients with mild-moderate daytime hypoxia or normoxia (PaO2 > 60 mmHg) may also have transient oxygen desaturation during sleep. Revisiting literature, the authors consider various features of this condition: the prevalence, causes, diagnostic procedures, symptoms, predisposing factors, consequences and the....

 Nocturnal oxygen desaturation during the sleep is very frequent in patients affected by chronic obstructive pulmonary disease (COPD). Hypoventilation, rather than sleeping apnea, is commonly considered as the most relevant factor in the onset of nocturnal oxygen desaturation. On this topic, the Authors have carried on a study on the nocturnal....

Forty-eight patients suffering from intermittent bronchial asthma underwent methacholine challenge test. Response was stronger in 29 patients and less pronounced in 19. The two groups had the same characteristics except for the cumulative methacholine dose which was lower in severe hyperresponsiveness. The patients were studied both in the phase of....

In the second semester of 1999, 246 patients, living in a Roman urban area, were subjected to a prick-test screening. 194 (78.9%) of the patients showed a positive answer toward almost one of the tested allergens, whereas the other 51 persons (21.1%) turned out to be negative. Of the patients with a positive cutireaction, 59 (24% of total survey an....
