We studied the relationship of the prevalence of a variety of respiratory symptoms to positive skin test reactivity (skin test index greater than or equal to 3) and/or eosinophilia (greater than or equal to 275 eosinophilic cells per cubic millimeter of blood) in a community-based population sample (N = 2805), adjusting for age, gender, area of residence, and cigarette smoking. We considered subjects with neither positive skin test reactivity nor eosinophilia to be the reference group. Positive skin test reactivity without eosinophilia (N = 487; 17.3%) was significantly associated with persistent wheeze (odds ratio value (OR) = 1.6; 95% confidence interval of the odds ratio value (CI) = 1.0 to 2.6) and with asthmatic attacks (OR = 3.2; CI = 2.0 to 5.3). Positive skin test reactivity in combination with eosinophilia (N = 92; 3.3%) was also significantly associated with persistent wheeze (OR = 2.7; CI = 1.2 to 6.0) and with asthmatic attacks (OR = 10.4; CI = 5.3 to 20.2), however, with a stronger association than in subjects with positive skin test reactivity alone. Finally, eosinophilia without positive skin test reactivity (N = 170; 6.1%) was significantly associated with chronic cough (OR = 1.8; CI = 1.2 to 2.7), bronchitis episodes (OR = 2.1; CI = 1.4 to 3.2), dyspnea grade greater than or equal to III (OR = 1.7; CI = 1.0 to 2.8), and asthmatic attacks (OR = 3.0; CI = 1.5 to 6.6).(ABSTRACT TRUNCATED AT 250 WORDS)

We report on a 37-year old patient with a simple viral infection who presented with acute bronchitis with bronchospasm, a productive cough and severe dyspnoea. Because of his specific occupational history--the patient is a forester and was exposed to wood dust and fungi--he was at high risk for extrinsic allergic alveolitis with mucoid impaction, so that the cause of hypoxemia and cyanosis was obvious. Repeated immunological parameters including gel-precipitations were negative: The lung function pattern (reduced vital capacity, a reduced FEV1, reduced flow values at low vital capacity and with the characteristic shape of the flow volume-curve but normal airway-resistance) suggested the diagnosis of intrinsic asthma limited to the small airways - "bronchiolar asthma" - severe small airway disease.

Seventy-four pulmonologists and one allergist were recruited to assess the efficacy and safety of iodinated glycerol (Organidin), 60 mg qid, vs placebo in patients with stable chronic obstructive bronchitis in a randomized, double-blind, placebo-controlled, parallel design. A total of 361 patients (180 to iodinated glycerol and 181 to placebo) who complained of cough and difficulty bringing up sputum entered the eight-week study. Evaluations were based upon eight primary symptom efficacy parameters (cough frequency, cough severity, chest discomfort, dyspnea, ease in bringing up sputum, patient and physician global assessments, and a derived patients' global assessment), and six secondary parameters (frequency of aerosol bronchodilator use, incidence and duration of acute exacerbations, frequency of concomitant medication use, incidences of adverse experiences and dropouts). Cough frequency, cough severity, chest discomfort, patients' ease in bringing up sputum, patients' overall condition, and a derived subject global assessment were significantly (p less than 0.05) improved by iodinated glycerol as compared with placebo within eight weeks of treatment. Dyspnea showed a trend toward improvement and the physicians' global evaluation showed no significant difference between groups. Similar findings were noted in a subgroup analysis of moderately-to-severely affected patients. The mean duration (days) of acute exacerbations and number of dropouts attributable to adverse experiences were significantly less (p less than 0.05) in the iodinated glycerol group.(ABSTRACT TRUNCATED AT 250 WORDS)

The fifth leading cause of death in the United States, chronic obstructive respiratory conditions, cannot be cured but can be considerably ameliorated by appropriate management. Many patients with COPD have a combination of chronic bronchitis, asthma, and emphysema. While the damage due to emphysema is permanent, many of the pathophysiologic changes of asthma and bronchitis can be reversed to some extent, and such reversal should be a goal of therapy. Smoking cessation will help the patient more than any other medical treatment. Bronchodilator therapy is best given by inhalation from a metered dose inhaler and on a maintenance basis. Be sure to check inhaler technique. An anticholinergic agent, eg, ipratropium bromide, is probably most effective, but many patients prefer a beta 2-selective adrenergic agent. Xanthines are currently third choice but are very useful to cover nocturnal dyspnea. Corticosteroids are usually only used in acute exacerbations and then only for short courses. If prolonged use is required, however, the inhalation route minimizes side effects to which these patients are particularly prone. Antibiotics are also usually only used in exacerbations, but one can be liberal with them. Use the less expensive broad-spectrum options for ten days. Some clinicians believe that hydration is an effective expectorant. Mucolytic therapy is extensively used outside the United States. The appropriate role of mucolytic therapy in the treatment of bronchitis remains to be more fully explored. Low-flow oxygen is only used in the prevention or treatment of cor pulmonale when the PaO2 is persistently at or below 55, or with a rising hematocrit and right-sided cardiac changes. If used, oxygen is helpful only when given long term for at least 18 h per day, not on a prn basis. Cardiac glycosides are probably of little benefit, but diuretics have an important role in treatment of fluid retention. Pulmonary vasodilator therapy is still experimental, as is almitrine. Prophylaxis with pneumococcal vaccine and annual influenza vaccine is rational but has not been proven to be of value. Exercise and activity should be encouraged for all except those with frank congestive heart failure. The role of "breathing exercises" is currently being reevaluated. Surgery has almost no place in the management of COPD. Anesthesia often results in postoperative complications in this disease. Avoid all sedatives and tranquilizers.

A study was made of the action of inhalation of a single atrovent dose in 20 patients with chronic obstructive bronchitis. All the patients demonstrated a considerable abatement or disappearance of dyspnea, and a reduction of the number of dry rales. The vital capacity of the lungs, the volume of forced expiration, maximal pulmonary ventilation, MOCmax, MOC50, and MOC75 substantially increased. The respiratory work diminished on the average by 32.3% primarily due to the lessening of non-elastic lung resistance. The rise of pulmonary static extensibility and reduction of pulmonary elastic propulsion were recorded. In patients with and without clinical signs of bronchospasm, the action of atrovent was identical.

We describe the case of a 23 years old male, who suffered a 45 bullet wound in the arm and upper right hemithorax. He walked after his injury and 10 minutes later presented dizziness, cough and tachycardia. On admission a minor haemothorax was seen on a chest X ray, but the bullet was not seen. Even without symptoms, an X ray of abdomen showed the missile lying above the left sacroiliac joint. A chest tube was placed, the patient had an excellent recovery and was discharged a week later. After several months he presented hemoptysis and a moderate pain on his right chest and was treated as an acute bronchitis. Six months after his initial injury he developed a florid picture of acute pulmonary embolism (chest pain, dyspnea, hemoptysis, tachycardia, severe cough). A new chest X ray was done and the bullet was shown lying in the right chest. A pulmonary arteriography located it in a lower basal branch. Through a posterolateral thoracotomy the slug was obtained. The recovery was uneventful and he has remained well since. We discuss the possible mechanisms to explain the entrance of the bullet into the vascular system and conclude that in cases of gunshot wounds: a) An exit wound must be always searched for; if not found exploratory X ray are mandatory, b) If the bullet is not found, specially after thoracic injuries, bullet embolism should be contemplated, c) If there are signs of regional ischemia arteriography is mandatory.(ABSTRACT TRUNCATED AT 250 WORDS)

A comparison between the action of Ambroxol and Acetylcysteine was carried out in 28 children aged 2 to 13 (mean 7 years 3 months) affected with spastic bronchitis. 14 patients were treated daily for 10 days by the oral route with 30 mg of Ambroxol (2 sachets) and 14 with 200-300 mg of Acetylcysteine (2-3 sachets). Quantity and quality of sputum, difficulty in expectorating, cough, dyspnea, bronchial bruits, were assessed before the treatment, 5 days into it and at the end. Both drugs were effective and well tolerated, but Ambroxol proved to be more rapid in achieving a satisfactory improvement than Acetylcysteine.

The present study has been tested on 30 children, 14 males and 16 females, average age 4.11 +/- 0.44 (range 9 months to 10 years), weight of 17.08 +/- 1.25 Kg, with infections concerning low respiratory tract (8 cases of broncho-pneumonia, 9 cases of acute bronchitis and 13 cases of lobar pneumonia). It has been used a chemotherapy composed of amoxycillin and clavulanic acid in pediatric suspension of 312.5 mg/5 ml (in the ratio of 4 to 1); the daily dosage, related to the children's weight has been of 43.91 +/- 1.21 mg/Kg in two daily doses. On the average the therapy has lasted for 6.43 +/- 0.19 days from a minimum of 4 to a maximum of 8 days. During the treatment the symptomatologic parameters (dyspnoea, cough), and the objective ones (pathological lung signs, rales, hypophonesis, bronchial breath...) have progressively improved till they have disappeared; morning and evening body temperature has promptly returned to normal. Both the physical and radiological exams of the chest confirm either the improvement or the regression of the infection in most of the cases. Side effects due to the antibiotic have not been registered and local and general tolerability was excellent. Considering the more or less fast and complete symptomatological regression, the evolution of the infective clinical picture and the tolerability, the final evaluations have been: excellent efficacy in 13 cases, good efficacy in 9 cases, fairly good in 5 cases and poor in 3 cases.

Forty-five acutely ill, coughing patients, three with acute dyspnea and cardiomegaly, and 37 control subjects were placed in lateral decubitus positions for auscultation of their dependent lungs to determine if this maneuver would elicit inspiratory crackles, signs of pneumonia. In the upright position, auscultation of the lungs was normal in all control subjects and in lateral decubitus positions their dependent lungs revealed transient late inspiratory crackles in seven of the 37 (18.9%), and transient inspiratory peeling sounds in two others (5.4%). Thirteen acutely ill, coughing patients, free of prior cardiac and pulmonary diseases, had persistent late inspiratory crackles induced in one or both dependent lungs when placed in lateral decubitus positions. These dependent lungs also revealed increased numbers of crackles in three patients, late inspiratory squeaks in four, and wheezes in three others. In the upright position, auscultation of the lungs was normal in 10 of these patients, and a few basilar crackles were heard in three others. All of these abnormal findings cleared after treatment with antibiotics. Thirty-one of 32 acutely ill, coughing patients with bronchitis, sinusitis, or pharyngitis were free of induced crackles in dependent lungs in lateral decubitus positions. However, placement of two other patients in these positions appeared to have elicited the inspiratory crackles of chronic pulmonary disease and early congestive heart failure. These observations suggest that placement of acutely ill, coughing patients into lateral decubitus positions for auscultation of the dependent lungs may be a valuable maneuver for diagnosis of pneumonia.

A 28-year-old female with known allergic bronchial asthma complained about increasing dyspnea, white sputum and fever. Pulmonary infiltrates progressed in spite of tetracycline administration. An increased leucocyte count, eosinophilia and an elevated sedimentation rate were found. Bronchoscopy was unrevealing except for signs of mild bronchitis. Eosinophils were abundant in the bronchial lavage. Eosinophilic pneumonia was diagnosed in a biopsy specimen. Prednisolone (100 mg/die initially, decreasing doses thereafter) led to significant reduction of infiltrates and eosinophilia. After 8 weeks of treatment the patient had completely recovered.
