An outbreak of adenovirus type 3 infection occurred in a hospital in 19 North American Indian infants and young children who were being treated for unrelated problems. Pneumonia occurred in 14 and was usually severe, with persistent signs of airway obstruction. Eleven of the 14 were followed periodically and complete medical reviews were conducted 8 to 10 years later. Ten had abnormal chest radiographs, and bronchography revealed bronchiectasis and minor airways changes in seven. In three cases there was clear evidence that these changes were directly related to the adenovirus type 3 infection. Pulmonary function studies showed a combination of restrictive and obstructive changes with minimal hypoxemia in most. Despite the presence of a persistent productive cough all were able to carry on a relatively normal life.

The differential diagnosis of a left lower lobe cavity in this young patient with a history of productive cough should include hiatal hernia, pulmonary abscess, bronchiectatic cyst and bronchopulmonary sequestration. Hiatal hernia should be ruled out by barium swallow; acute pulmonary abscess by the lack of a history suggestive of a necrotizing pneumonia; bronchiectasis by bronchogram; and intralobar bronchopulmonary sequestration should be confirmed by aortography.

A 69-year-old male with bronchial asthma was admitted to a hospital with fever, dyspnea, and productive cough. Arterial blood gas analysis revealed sever hypoxemia (PaO2 54.8 torr, PaCO2 28.8 torr). Chest roentgenogram showed diffuse reticulonodular shadows predominantly in the upper filed and a small amount of bilateral pleural effusion. CT image of the lung showed nodular opacities at the peripheral branches of the pulmonary arteries and bronchi, some of which had become confluent. The bronchoarterial bundle had become thicker compared with a CT taken 18 months before this admission. Three days treatment with antibiotics and gamma globulin did not change the symptoms or radiologic findings. After commencing methylprednisolone therapy, the pneumonia showed rapid improvement. Based upon the significant elevation of serum influenza B (B/Singapore/79) virus antibody titer, the patient was diagnosed as having influenza B viral bronchopneumonia. Twenty-three days after initiation of steroid therapy, slight nodular opacities were observed on CT. This finding suggests that bronchiolitis has a relatively prolonged course in influenza viral bronchopneumonia.

4 cases of Pneumocystis carinii pneumonia in HIV-infected patients studied at the University of Zambia Medical School, Lusaka, were verified by bronchoalveolar lavage. Pneumocystis is common in North American AIDS patients, but has been considered rare in Africa. One reason may be that facilities for diagnosis, bronchoscopy with bronchoalveolar lavage, are not usually available. 44 consecutive HIV seropositive patients who were unresponsive to a 10-day course of antibiotics, and whose sputum was negative for acid fast bacteria, underwent bronchoalveolar lavage from February 1990 to December 1990. HIV status was assayed with Welcozyme ELISA kits, and P. carinii was detected with toluidine blue O stain. The 1st case of confirmed P. carinii pneumonia was a 35-year old man who had a productive cough for 4 weeks, fever, and dyspnea. He was treated with co-trimoxazole and was symptom-free in 3 weeks, but developed severe Stevens-Johnson reaction. His cultures were positive for M. tuberculosis at week 8. He was lost to follow-up. The 2nd case was a 26-year old man with a 6-month history of cough and white sputum, treated without effect with antituberculous medication. He improved over 3 weeks with co-trimoxazole, but died of respiratory failure 2 months later. The 3rd case was a 30-year old woman being treated for pulmonary tuberculosis, who became progressively dyspneic 7 months later. She developed a generalized maculo-papular rash after taking co-trimoxazole, so was given dapsone 100 mg/day, prednisone 1 mg/kg/day, and trimethoprim 15 mg/kg for 1 week. She improve in 3 weeks. The 4th case was a 30-year old man with a 4-week history of dry cough and dyspnea and recent high fever. He was given co-trimoxazole, but developed generalized purpura after 5 days. His treatment was changed to Dapsone 100 mg/day, prednisone 1 mg/kg/day, and antituberculous medication. He improved after 3 weeks, and is being maintained on Fansidar 1 tablet/week. These cases are remarkable because 2 of them also had pulmonary tuberculosis, which is often the presumed diagnosis of pneumonia in African AIDS patients. Furthermore, 3 developed serious drug reactions to co-trimoxazole, also considered an uncommon occurrence.

In order to compare the etiology, clinical manifestation, and prognosis of patients acquiring nosocomial pneumonia, we studied and compared twenty normal hosts who acquired nosocomial pneumonia from Jan 1, 1989 to Dec 31, 1989 (group 1) with fifty-four immunocompromised patients with nosocomial pneumonia who were admitted between 1984 and 1990 (group 2). Both groups were similar in some patterns such as: gram-negative bacilli were common (75%, 60%), the chest roentgenogram showed initial localized lesions (75%, 73%), there was a history of prolonged hospitalization (27, 33 days) and a high mortality rate (60%, 50%). The differing findings were that the first group acquired pneumonia more often during the first 7 days after admission; transbronchial aspiration was believed to be the route of entry and most of the patients had productive cough. Blood cultures rarely yielded the organisms (5%). The second group had pneumonia at a mean of 33 days after admission, hematogenous spread to the lungs was common and blood cultures yielded the etiologic organisms more often (40.7%).

Two sisters with alpha 1-antitrypsin deficiency and bronchiectasis are reported. The 53-year-old older sister (propositus) had pneumonia 3 times during her forties. She developed dyspnea on exertion in February, 1988, and a few months later she was seen at our hospital. Her serum alpha 1-antitrypsin level was 11 mg/dl. Vascular markings on chest X-ray were mildly decreased. Bronchography showed generalized cystic bronchiectasis. The younger sister was seen at our hospital at the age of 50. She had been in good health until one year previously when she had developed pneumonia, and thereafter she had suffered from productive cough and dyspnea on exertion. Her alpha 1-antitrypsin level was 22 mg/dl. Chest X-ray showed ring-like shadows and tram lines. Chest CT scans of both sisters revealed cystic changes, dilatation of bronchi, and the connection of these lesions diffusely. The alpha 1-antitrypsin phenotype of these sisters was found to be PiSiiyama (homozygote). Family study revealed that alpha 1-antitrypsin levels of 7 members were intermediate and no members had symptoms. We consider that bronchiectasis may have been related to alpha 1-antitrypsin deficiency in these sisters.

A 71-year-old man was admitted to the Wake Forest University/Baptist Hospital Medical Center on February 1, 1989, with pharyngitis and a cutaneous eruption that began that day. The past history was significant for a diagnosis of chronic lymphocytic leukemia (CLL) made in 1984, and for longstanding hypertension, severe coronary artery disease, and prostatic hypertrophy. The patient had required no therapy for his CLL until August, 1988, when he developed hemolytic anemia and was treated with oral chlorambucil, 4 mg/day, and a tapering course of prednisone. By December, 1988, the prednisone therapy had been discontinued, but the patient required hospital admission for pneumococcal pneumonia, which responded well to intravenous antibiotic therapy. One day prior to the current admission the patient complained of persistent fevers, sore throat, productive cough, and headache. He noted a new cutaneous eruption on the day of admission in February, 1989. The past history was positive for occasional herpes stomatitis. The patient did not know if he had previously been infected with varicella. Skin examination revealed multiple (greater than 20), single, and grouped vesicles in a generalized distribution involving the bilateral trunk, head, neck, arms, and legs. The heaviest involvement was on the right posterior auricular area and on the neck. A Tzanck preparation obtained from an early lesion was positive for multinucleated giant cells. Viral culture was negative at 24 hours and at 1 week. A skin biopsy of an early vesicular lesion was performed and revealed intraepidermal vesicles with acantholysis and giant cells.(ABSTRACT TRUNCATED AT 250 WORDS)

An 18-year-old man was admitted to Hamamatsu University Hospital on February 15, 1985, with high fever, vesicular and papular rash involving the skin and mouth, conjunctivitis, productive cough and dyspnea. A diagnosis of Stevens-Johnson syndrome was made by skin biopsy, and chest X-ray showed an infiltrate in the right lower lung filed. Despite treatment with corticosteroids and antibiotics, the mucocutaneous lesions did not heal, and the pneumonia progressed to both lung fields. Because the patient had developed dyspnea, a tracheotomy was performed, mechanical ventilatory support was instituted, and high-dose corticosteroid therapy was started. However, jaundice due to intrahepatic cholestasis, hematuria, hematochezia, sepsis, and subcutaneous and mediastinal emphysema ensued, and the patient died of respiratory failure on March 1. Postmortem examination of the lung demonstrated diffuse alveolar damage. The complement-fixation titer for Mycoplasma was 1:64, compared with a level of less than 1:4 on admission. This case was though to be one of fulminant Mycoplasma pneumoniae infection presenting with Stevens-Johnson syndrome, respiratory failure and other extra-pulmonary complications.

A 65-year-old man was admitted to our hospital complaining of productive cough, dyspnea and stridor. Chest X-ray disclosed overinflation with micronodular infiltrates. Blood examination showed mild eosinophilia and IgE elevation. Pulmonary function test disclosed severe airway obstruction and diffusion capacity impairment. Although clinical improvement was achieved after bronchodilator therapy, laboratory abnormalities continued. Open lung biopsy demonstrated mononuclear cellular and eosinophilic infiltration at alveolar lumen and vessel walls without prominent fibrosis, which was compatible for prolonged eosinophilic pneumonia. From above findings, this case was thought as a prolonged eosinophilic pneumonia combined with pulmonary emphysema and bronchial asthma.

A 25-year-old male was admitted with productive cough and an abnormal shadow on chest X-ray film which showed a cylindrical shadow near the left hilum and consolidation in the markedly hyperlucent left upper lung field. The cylindrical shadow appeared to be located in left S1+2 but bronchographic examination showed independence of the branches of B1+2. Furthermore, pulmonary venography by DSA showed that the left upper pulmonary vein entered the left brachiocephalic vein. The patient underwent left partial lobectomy under a diagnosis of congenital bronchial atresia with partial anomalous pulmonary venous drainage. Pathological examination of the resected lung revealed obstructive pneumonia in the over-inflated lung zone, probably induced through collateral airways.
