The objective of our study was to determine the safety of transbronchial biopsy (TBB) in nonhospitalized patients. The design was a prospective study of the consecutive cases from July 1987 until September 1988 in the setting of a university hospital of the third level with 1,800 beds. The patients were a consecutive sample of 169 patients who had 184 procedures of fiberoptic bronchoscopy (FOB) with TBB performed. They suffered from different diseases: lung nodules or masses, diffuse interstitial disease, alveolar condensation, etc. An FOB with TBB was performed in immunocompetent outpatients, who were kept under observation for four hours and then had a chest roentgenogram taken afterwards. We contacted them again after 72 hours to rule out delayed complications. In three cases, more than 100 ml of blood were obtained during the FOB, without significant hemoptysis being recorded in those patients during the observation period; chest pain occurred in 15 patients during the TBB; pneumothorax occurred in two patients (1 percent), one of whom required admission to the hospital, without requiring chest tube drainage. Other complications are reported (bronchospasm, parenchymal hemorrhage, and pneumonia). In conclusion, we consider the TBB to be a technique with a low incidence of complications for outpatients, so therefore we do not believe that admission to the hospital is mandatory for this type of patient, although we do recommend a longer observation period.

Endobronchial neoplastic disease is rarely encountered in patients under 20 years of age. The great majority of these lesions are carcinoids or mucoepidermoid carcinoma. Symptoms are secondary to bronchial irritation and manifest as recurrent pneumonitis, hemoptysis, persistent cough, reactive airway disease, and chest pain. Early bronchoscopy reliably enables identification and may prevent harmful sequelae resulting from delay in diagnosis. Retrospective data from four cases collected from the Tumor Registry in the Southern California Kaiser Permanente Medical Group is presented and a review of the literature is discussed.

Endoscopic esophageal variceal sclerotherapy (EVS) is often used in the treatment of upper gastrointestinal hemorrhage due to esophageal varices. We retrospectively reviewed the Mayo Clinic experience with EVS between 1980 and 1989 to determine the incidence of thoracic manifestations and chest roentgenographic abnormalities associated with this procedure. The study population consisted of 223 patients who underwent 390 EVS procedures. In all patients, chest roentgenography was done before and after EVS. Ethanolamine oleate or tetradecyl sulfate was used as the sclerosant. Fever, chest pain, and odynophagia were frequent findings after EVS and tended to be short-lived. Local complications at the site of injection, such as esophageal perforation (in 1% of EVS procedures) and abscess (in 0.3%), were infrequent but associated with substantial mortality. Esophageal stricture was noted as a late complication in less than 10% of patients, and clinically recognized aspiration pneumonitis was rare. Respiratory insufficiency developed after 14 EVS procedures. Chest roentgenographic abnormalities, which were commonly detected (after 85% of EVS procedures) but were rarely of clinical significance, included retrocardiac or mediastinal widening or densities (in 35%), pleural effusions (in 27%), atelectasis (in 12%), and pulmonary infiltrates (in 9%). Most thoracic manifestations after EVS are likely due to a local inflammatory response to the sclerosant.

Outcome and prognostic factors were prospectively studied in 277 adult patients (average age 62 yrs) with community-acquired pneumonia requiring hospitalization. The aetiology was established in 68%, with S. pneumoniae as the predominating agent. Mortality was 4% (12 of 277), and all but one who died were greater than or equal to 60 yrs of age. Features associated with high mortality included greater age, absence of chills and chest pain, high respiratory rate (greater than 30 breaths.min-1) and low serum albumin on admission, and the occurrence of airway colonization and secondary infection during hospital stay. Multivariate analysis showed that low serum albumin and the occurrence of secondary infection, but also absence of chills and airway colonization, were correlated to a higher mortality. In patients who survived, the median length of hospital stay was seven days, and at follow-up, about eight weeks after admission, 81% had recovered and chest X-ray was normal in 84%. In conclusion, we believe that the outcome of community-acquired pneumonia can be influenced by prophylactic measures against pneumococcal infection, and an increased surveillance of risk patients.

A 74-year-old man complained of a cough and left chest pain. Chest X-ray showed marked pleural effusion and a large mass in the left lower lobe, and air bronchograms within the mass were observed by tomography and computed tomography (CT). About 3 months later, the patient died of left atelectasis and pneumonia. Autopsy revealed a localized tumor in the lower lobe of the left lung. Histologically, proliferation of lymphoma cells was noted. Immunoglobulin staining showed B cell-type monoclonality. No metastasis was evident except for a very small nodular area in the left renal cortex.

A 24-year-old heterosexual male, HIV-infected intravenous drug addict, with necrotizing pneumonitis and empyema due to Streptococcus cremoris is presented. The patient had fever, severe dyspnea and chest pain. Chest roentgenogram demonstrated pleural effusion on the left side. A thoracocentesis revealed purulent exudate and S. cremoris was isolated. Fever and pleural effusion disappeared with penicillin and clindamycin therapy. The most likely source of the infection was ingestion of unpasteurized milk and cheese.

There has been increased recognition of adenosquamous lung carcinoma since the 1982 modification of World Health Organization (WHO) histologic criteria. However, data on clinical features of this histologic subtype were nonexistent. Medical records of 127 patients with adenosquamous lung carcinoma were reviewed to determine the clinical features, namely, age, race, sex, smoking history, asbestos exposure, symptoms present at the time of diagnosis, stage, treatments, and survival. The age distribution was: less than 40 yr, 3%; 40 to 49, 17%; 50 to 59, 28%; 60 to 69, 32%; 70 to 79, 18%; greater than or equal to 80, 2%. Men constituted 72%, and 90% were smokers. Four smokers had documented asbestos exposure. The symptoms in order of decreasing frequency were cough, weight loss, expectoration, anorexia, chest pain, dyspnea, weakness, hemoptysis, pneumonia, fever, nausea, vomiting, dizziness, and chills. Stage could be ascertained in 120 (95%) patients. Local stage constituted 10%, regional constituted 30%, and distant constituted 60%. Local stage had the best survival, with a projected 5-yr survival of 62%. Median survivals in regional and distant stages were 8 and 4 months, respectively. Symptoms of adenosquamous lung carcinoma were similar to other histologies. Most patients present in regional or distant stages. Local-stage patients had a good long-term survival after surgical excision of the tumor.

Fifteen patients, eleven males and four females, with amiodarone induced pulmonary disease were studied. Their ages ranged between 52 and 79 (mean = 64.0) years. 66% of the patients were taking a daily dose of 200 mg of amiodarone. The time elapsed between the initial dose and the diagnosis of the pneumonitis varied from 2 to 84 (mean = 23.3) months. Premature ventricular beats and recurrent episodes of paroxistic supra ventricular tachycardia were the most common indications for the use of the drug. The most frequent clinical complaints were progressive dyspnea and cough. Weight loss was observed in five patients, fever in six and chest pain in two. The most habitual thoracic physical sign was diffuse crepitation. Chest roentgenograms disclosed bilateral interstitial infiltrates in all patients, associated to pleural effusions in two. An increased diffuse uptake of 67 gallium citrate was observed in the nine patients to whom it was done. Lung function tests showed a pattern of restrictive ventilatory respiratory insufficiency and hypoxemia. Lung tissue specimens were obtained in ten patients, bronchoalveolar lavage in one and pleural fluid in one. The material was examined by light and electron microscopy. Amiodarone was discontinued in all patients and corticosteroids were introduced in thirteen. Five patients (33.3%) died, eight improved and two remained with radiographic scars.

A 88-year-old man was admitted because of the left chest pain due to herpes zoster for 1 week. Blood analyses and immunoelectrophoresis revealed anemia, severe neutropenia, rouleaux formation and IgM, lambda-type monoclonal gammopathy. The HE staining and peroxidase-anti-peroxidase staining of biopsy specimens of the cervical lymph node swelling appeared from the fifth hospital day, revealed an increase in atypical lymphocytes bearing IgM, lambda-type immunoglobulin. Then a diagnosis of primary macroglobulinemia was made. Although the patient's clinical findings transiently improved after chemotherapy with prednisolone and vindesine, he died of a septic shock which appeared after klebsiella pneumonia and sepsis. We reported an unusual case of primary macroglobulinemia with severe neutropenia, leading to a rapid development of septic shock after the chemotherapy.

Human immunodeficiency virus (HIV) infection is associated with abnormalities of humoral immunity that result in an increased incidence of bacterial pneumonia. From 2% to 10% of acquired immunodeficiency syndrome (AIDS)-associated pneumonia is caused by encapsulated bacteria. Clinical features are usually typical of community-acquired pneumonia and include fever, productive cough, and chest pain. Focal radiographic infiltrates, an elevated WBC count, and mild hypoxemia are commonly observed. Streptococcus pneumoniae, Haemophilis influenzae, other Streptococcus species, and Branhamella catarrhalis are the predominant organisms. Bacteremia is frequent, especially with S pneumoniae infections. Despite a rapid response to antibmicrobial agents, many patients experience recurrences. Prevention of bacterial infections with prophylactic antibiotics and immunizations is recommended for selected HIV-infected patients.
