The clinical and epidemiologic features of 73 patients with laboratory-confirmed blastomycosis who were identified over an 11-year period in North Central Wisconsin are presented. Pulmonary disease was the sole manifestation in 77% of patients. More than one-half of all patients had symptoms that included fever, cough, weight loss, night sweats, and pleuritic chest pain. Virtually all were previously healthy, and most did not have an outdoor occupation. However, 82% of these patients lived or had visited within 500 m of rivers or associated waterways. The majority experienced the onset of symptoms between December and April. The estimated mean annual incidence rate of infection for Vilas County was 40.4 cases per 100,000 persons, and that for the largest city in the county was 101.3 cases per 100,000 persons. Several areas with an exceptionally high incidence of the infection were observed. We suggest that, in regions where blastomycosis is hyperendemic, clinical disease is most often pulmonary and occurs in immunocompetent individuals and that residence near an ecological focus may be a greater risk factor for acquisition of blastomycosis than is occupation.

Levodropropizine is a recently developed, peripherally active antitussive agent which is widely used in clinical practice. In order to obtain further information on the spectrum of activity of this compound in experimental clinical models, a double-blind controlled study was carried out to evaluate the potential effect of the drug against cough and bronchoconstriction induced by inhalation of an ultrasonically nebulized solution of distilled water in patients with obstructive lung disease. Twenty patients were randomly divided into two groups, which received levodropropizine (60 mg t.i.d.) or placebo respectively for 7 consecutive days. Parameters evaluated at baseline and on the last day of treatment included (i) results of respiratory function tests (FEV1, IVC, FVC, TIFF, PEF, MEF75, MEF50, MEF25) performed before the stimulation test with nebulized water; (ii) total number of coughs during a 2-hour period after the stimulation test; (iii) bronchial responsiveness, quantified by calculating the volume of nebulized water required to induce a 20% reduction of FEV1 below the basal level. At pretreatment, the tussive response was very similar in the two groups. A significant decrease in number of coughs (from 34.4 +/- 8.4 at baseline to 15.6 +/- 4.9 post-treatment, p less than 0.01) was observed after administration of levodropropizine, whereas placebo treatment produced no significant effect (number of coughs: 29.6 +/- 4.9 at baseline vs 24.8 +/- 9.6 post-treatment, N.S.). Bronchial responsiveness decreased significantly (compared to baseline) in both treatment groups, without any significant difference between drug and placebo. Respiratory function tests were not significantly affected by either treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Cough is a powerful physiological reflex mechanism that causes central airways to be cleared of foreign material and excess secretions. Chronic cough is a very common presenting symptom in general practice with a prevalence in the population of about 5%. As a general rule, persistent cough represents organic disease of the upper and lower airways, the lung parenchyma, the pulmonary circulation, the pleural space, the mediastinum and the upper gastro-intestinal tract. The most common cause is cigarette smoking, but virtually any chronic lung disease may be occasionally associated with cough. Complications of coughing are tussive syncopes, rib fractures, rupture of respiratory muscles and eventually hernias. Based on a detailed clinical history and physical examination, the investigation includes a chest radiograph, spirometry, and sputum smears. Radiography of the sinuses, bronchoscopy and upper gastro-intestinal endoscopy may be added. If the treatment of an underlying disease is successful, chronic cough may disappear. There are few 'antitussive' drugs with proven suppression of the cough reflex.

A case of fulminant disseminated pulmonary adiaspiromycosis is reported. The patient, a 35-year-old black male farm worker, presented with a four-week history of generalized weakness, unproductive cough, evening fever, and a weight loss of 8 kg. He died 12 days after hospitalization of respiratory failure due to granulomatous lung disease. The clinical and radiographic findings were indistinguishable from those of miliary tuberculosis. Microscopic examination of material obtained at autopsy revealed the large fungus characteristic of adiaspiromycosis in the center of suppurative granulomas throughout the lungs. This is believed to be the first fatal case of pulmonary adiaspiromycosis reported in humans, and it may have been occupationally acquired.

Transtracheal oxygen therapy is being used with increasing frequency because it is an effective mode of oxygen delivery and is well tolerated by patients. An increase in cough and mild intermittent hemoptysis are not uncommon in the early postinsertion period but usually resolve spontaneously. Herein we present two individuals of short stature with restrictive lung disease who had persistence of excessive cough and mild hemoptysis after insertion of a standard catheter (SCOOP). Bronchoscopic evaluation in one revealed erosions of the mucosa over the carina and take-off of the right main-stem bronchus. Symptoms resolved in both individuals following placement of a shorter catheter. We suggest that greater consideration be given to matching transtracheal catheter length to patient lung size, particularly in the face of severe restrictive lung disease.

A link between cigarette smoking and "acute chest syndrome" in sickle cell anemia is suggested. Acute chest syndrome in the patient with sickle cell anemia is characterized by fever, leukocytosis, cough, chest pain, and pulmonary infiltrates in the chest radiograph. This article describes the results of a study of 69 adolescent and young adult sickle cell anemia patients. Twenty-nine of these patients were smokers, three were former smokers, and 37 were nonsmokers. Patients completed respiratory questionnaires that focused on smoking habits and included a history of chest syndrome. Information obtained was confirmed by review of clinical records. The chi-square test demonstrated a strong relationship between cigarette smoking and chest syndrome in sickle cell anemia. All 29 smokers had a history of chest syndrome, but only 24 of 37 nonsmokers had such a history. Although the exact mechanism of the relationship between smoking and the development of acute chest syndrome remains speculative, cigarette smoking joins infection, hypoxia, acidosis, infarction, dehydration, and analgesics as a causative factor in adolescent and adult patients with sickle cell anemia. Behavioral modification of the smoking habit in patients with sickle cell anemia may decrease the frequency of acute chest syndrome and sequelae of sickle cell lung disease.

Wood trimmers are exposed to molds that periodically grow on timber that may induce alveolitis and obstructive lung disease. We have evaluated respiratory symptoms, bronchial reactivity, and lung function in 28 wood trimmers at a Swedish sawmill and in 19 unexposed office workers. Eleven (sero-positive) of the wood trimmers had precipitating antibodies in peripheral blood against one or several molds. The exposure to dust (median 0.26 mg/m3), viable mold spores (median 2950 cfu/m3), viable bacteria (median 370 cfu/m3), airborne endotoxins (range 0.0015-0.0025 microgram/m3), and terpenes (range 0.4-23 mg/m3) was lower than levels that earlier have been reported to affect lung function. The wood trimmers reported an increased prevalence of cough and breathlessness. They also showed signs of a mild obstructive impairment with a tendency to increase bronchial sensitivity to metacholine and decreased FEV1 after 2 days free from exposure. FEV1 decreased more during the working week in the sero-positive workers than among the sero-negative workers, and for the whole group the decrease in FEV1 and MEF25 was correlated to the degree of mold exposure.

The altered carbohydrate structure of sputum from patients with cystic fibrosis (CF) has been thought to be due to the inflammatory airway response. Carcinoembryonic antigen (CEA) and CA 19-9 detect sialosylated carbohydrates in mucus. The epitope of CA 19-9 is part of the Lewis A (Le(a)) blood group antigen. Serum concentrations of CEA and CA 19-9 were determined by radioimmunoassay in 41 CF patients, aged 6-34 years; 16 were asymptomatic Outpatients, and 25 had been admitted for pulmonary exacerbations. There was no difference in CEA between groups. The CA 19-9 serum concentration was elevated in 90% of patients who had at least one of the two Lewis antigens. The CA 19-9 concentration of Inpatients with exacerbations was 2.7 times that of stable Outpatients (263 +/- 44 versus 99 +/- 13 U/mL; P less than 0.02). CA 19-9 correlated significantly with age (r = 0.35, P less than 0.05), Brasfield score (r = 0.39, P less than 0.015), pulmonary function tests, cough severity (r = 0.50, P less than 0.001) and NIH clinical score (r = 0.57, P less than 0.001). CA 19-9 concentration of Inpatients decreased by 44% from admission to discharge (302 +/- 45 to 169 +/- 39, P less than 0.02). Fourteen of 25 (56%) of the Inpatients were Le(a) positive versus only 3/15 (20%) of Outpatients who had milder lung disease (P less than 0.002). Of the Inpatients, 25% with more advanced lung disease were Le(a+b+), a rare blood group in the normal population, and one not observed in the Outpatients with milder disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Respiratory syncytial virus (RSV) is the most important cause of lower respiratory tract infection in infants and young children. The charts of 17 children found to have RSV among 493 children who underwent liver transplantation between February 1985 and February 1991 were reviewed. The median age at diagnosis was 20 months. Median time of diagnosis was 24 days after transplantation. Thirteen patients developed nosocomial infections while convalescing from their transplant. Common symptoms included tachypnea, cough, fever, and congestion. Acute radiographic changes were seen in 12 patients. Two deaths were associated with progressive pulmonary disease and occurred in children with infection early in the postoperative period who were intubated before the onset of symptoms. RSV in children after liver transplantation has a clinical spectrum similar to that in normal children. Early onset of infection (less than 20 days) after transplantation and preexisting lung disease may predict more severe disease.

Invasive pulmonary aspergillosis usually occurs in severely immunocompromised or neutropenic patients. Six patients with invasive aspergillosis are described whose only defence impairment was underlying lung disease and corticosteroid treatment. Cough, fever, and sputum production were the usual reasons for presentation and four patients developed the sepsis syndrome. Radiographic findings included de novo cavitation in three patients and rapid radiographic progression in four. Aspergillus species were isolated from respiratory secretions of all patients early in the course of the disease. Treatment was effective in only two patients and the subsequent progress of the others was consistent with a chronic necrotising process. Invasive pulmonary aspergillosis is uncommon in patients with respiratory diseases receiving corticosteroids, but should be considered when pneumonia and cavitary infiltrates occur.
