We describe 11 elderly patients with bacteriologically proved endobronchial tuberculosis, representing 15% of our 73 geriatric patients with pulmonary tuberculosis in the period 1980 to 1987. In seven (64%) of the 11 patients, an incorrect diagnosis was initially made. Cough, mostly nonproductive, was invariably present, and general symptoms (fever, anorexia, weight loss) predominated over specific pulmonary symptoms. The radiographic features were rather "unusual": in only two (18%) of the 11 cases, apicoposterior consolidations with or without cavitation were found. Fiberoptic bronchoscopy showed a range of endobronchial abnormalities that included ulcerations, mass lesions, and fibrostenoses. Antituberculous treatment generally led to satisfactory results. Still, residual bronchostenosis was observed in four (57%) of seven patients in whom a control bronchoscopy was done. In one of these four patients, a pneumonectomy had to be performed for uncontrollable retro-obstructive infections, and in another, repeated endoscopic dilatations were effective. In elderly patients, endobronchial tuberculosis should be considered in the differential diagnosis, especially in the presence of chronic cough. In these patients, the chest roentgenogram may be clear or suggestive of bronchial carcinoma or pneumonitis.

Carcinoid tumors of the lung are rare in childhood. Still they have to be taken in account as a possible reason for chronic pneumonitis, (with) cough or even hemoptysis. Misinterpretation of symptoms is the cause for the frequently long time lapse before the correct diagnosis is established. The crucial examinations are the history of symptoms, chest X-ray, tomography, and bronchoscopy, which lead to the correct diagnosis in about 75% of the cases. Treatment of choice is operative, with the aim to conserve as much functioning lung as possible. Radiotherapy has only palliative effects. The prognosis is rather good for the carcinoid tumor of the lung in general, 80% achieve a 5 years survival rate. The carcinoid tumor of the lung is now as for the newest definition defined as a separate group and should not be mixed up with "bronchial adenomas". Adenoid cystic carcinoma (cylindroma) and mucoepidermoid carcinoma of the bronchus are defined as carcinomas and believed to arise from respiratory glands.

A twenty-four year old male Peruvian of Japanese origin, who came to Japan in September 1990 and had been working in a minor factory in a rural area, was admitted to a hospital in March '91 with severe cough. Smear examination of his sputum smear was positive for acid-fast bacilli and his chest X-ray showed multiple cavities (Index case). Subsequent contact examination identified further four patients with pulmonary tuberculosis among his colleagues in the factory, all of whom lived in the same house with the index case. During following three years, further six patients with mycobacteriosis, two Peruvians and four Japanese, were found among the employee of that factory. M. tuberculosis was cultured from the sputa obtained from seven of these eleven patients. Another patient was diagnosed as non-tuberculous mycobacteriosis. Restriction fragment length polymorphism (RFLP) analysis carried out with five strains of M. tuberculosis isolated from these patients revealed the identical RFLP pattern which is uncommon in Japan. Still more, an isolate from another patient was subjected to RFLP analysis by chance, and was found to show the same RFLP pattern. Later epidemiological study revealed that the last patient, a 53 year-old saleswoman of boxlunch, might have some contact with the index case at her booth. Though RFLP analysis was not done for the isolate from the index case, from the identity of RFLP patterns of other isolates, clinical course and epidemiological study, it is considered that six patients were certainly, and two others were probably infected from the index case.(ABSTRACT TRUNCATED AT 250 WORDS)

Chronic granulomatous disease of childhood is an inheritable disorder of phagocytic cell respiratory burst resulting in recurrent, life-threatening, catalase-positive infections. The lung is the most common site of infection, and pulmonary disease is the primary cause of death in greater than 50% of children with chronic granulomatous disease. Still, the role of surgery in management of this disease remains undefined. Between 1974 and 1990, 19 patients with chronic granulomatous disease required 31 thoracic interventions at our institution. Patients ranged in age from 2.5 to 27 years (mean age, 15 years). Seventeen of 19 patients (89%) had had previous pulmonary infections. Patients presented as toxic (temperature > 38.5 degrees C, chest pain, and cough) in 22 instances before the 31 procedures. Aggressive surgical intervention for diagnosis and extirpation of localized infections was undertaken with lobectomy/pneumonectomy with or without other procedures (5), bisegmentectomy (2), segmentectomy with or without other procedures (5), or wedge with or without other procedures (13). In five instances, an empyema was drained; a chest tube for a sterile collection was placed in one instance. There was one intraoperative death, and 3 patients died 22 to 600 days postoperatively with overwhelming sepsis. The mean hospitalization was 101 days (range, 24 to 600 days). Wound complications occurred in 5 patients, requiring 17 separate anesthetic debridements. A change in therapy was dictated by the results of the procedure in 23 of 31 instances (74%). Thoracic surgeons must be aware of this rare cause of immunosuppression in these children and, due to the unusual nature of the pulmonary infections, should follow an aggressive approach in their diagnosis and management.

Compelling evidence suggests a causal relation between exposure to parental cigarette smoking and respiratory symptoms during childhood. Still, the roles of prenatal versus postnatal parental smoking need clarification. In this study, the authors assessed the effects of passive smoking on respiratory symptoms in a cohort of over 1,000 children born during 1980-1984. The children were enrolled in the Tucson Children's Respiratory Study in Tucson, Arizona, and were followed from birth to age 11 years. The population was generally middle class and consisted of two main ethnic groups, non-Hispanic Whites (75%) and Hispanics (20%), reflecting Tucson's population. Information on parental smoking and on wheeze and cough in their children was elicited from parents by using questionnaires at five different surveys. Data were analyzed both cross-sectionally and by using the generalized estimation equation approach, a longitudinal mixed-effects model. The best-fitting model indicated that maternal prenatal but not postnatal smoking was associated with current wheeze (odds ratio = 2.3, 95% confidence interval 1.4-3.8) independently of a family history of asthma, socioeconomic factors, and birth weight. This effect was time dependent and significant only below age 3 years; although independent of gender, the association was stronger for girls (odds ratio = 3.6, 95% confidence interval 1.6-8.0). Cough was not associated with parental smoking during the first decade of life. This transitory effect of maternal prenatal smoking on wheezing could be due to changes that affect the early stages of lung development.

This case study was undertaken to describe the use and limitations of glossopharyngeal breathing (GPB) by a ventilator-dependent, tracheotomized patient after cervical tumor resection. A 6-yr, 8-mo-old, tracheotomized, ventilator-dependent boy, after cervical tumor resection, learned GPB on his own and used it for ventilator-free breathing. Over the next 16 yrs, his GPB efficacy improved to the point that, with a vital capacity of 670 ml, his GPB maximum single-breath capacity increased to 3300 ml. This was limited by the fact that at 2.9 l of lung volume, air began to leak around the tracheostomy tube walls and out of the stoma. Still, GPB permitted up to 12 hrs/day of ventilator-free breathing. Measurements of assisted peak cough flow and GPB lung insufflations exceeding vital capacity are the main measures that demonstrate adequate tube fit to permit effective GPB in the presence of an indwelling tracheostomy tube.

The prevalence of heterotopic gastric mucosa (HGM) in the cervical esophagus is frequently underestimated. Tiny microscopic foci have to be distinguished from a macroscopically visible patch, also called "inlet patch." Symptoms as well as morphologic changes associated with HGM are regarded as a result of the damaging effect of acid, produced by parietal cells in the mostly fundic type of HGM. We herein review the literature and propose a new clinicopathologic classification of esophageal HGM: Most of the carriers of esophageal HGM are asymptomatic (HGM I). Some individuals with HGM in the esophagus complain of dysphagia, odynophagia, or "extraesophageal manifestations" (hoarseness and coughing), without further morphologic findings (HGM II). Still fewer patients are symptomatic due to morphologic changes, i.e., esophageal strictures, webs, or esophagotracheal fistula (HGM III). Malignant transformation via dysplasia (intraepithelial neoplasia, HGM IV) to cervical esophageal adenocarcinoma (HGM V) is exceedingly rare (only 24 reported cases). In contrast to Barrett's esophagus, HGM should not be regarded as a precancerous lesion. Symptoms are more likely to occur in patients with inlet patch, whereas malignant transformation and adenocarcinogenesis can also occur in microscopic HGM foci. Asymptomatic HGM requires neither specific therapy nor endoscopic surveillance. Only in symptomatic cases treatment, i.e., dilatation for (benign) strictures or acid suppression for reflux symptoms, can be recommended. Patients with low-grade dysplasia in HGM might be candidates for surveillance strategies, whereas in cases of high-grade dysplasia and invasive adenocarcinoma oncological treatment strategies must be employed.

Historical aspects of respiratory reflexes from the lungs and airways are reviewed, up until about 10 yr ago. For most of the 19th century, the possible reflex inputs into the "respiratory center," the position of which had been identified, were very speculative. There was little concept of reflex control of the pattern of breathing. Then, in 1868, Breuer published his paper on "The self-steering of respiration via the Nervus Vagus." For the first time this established the role of vagal inflation and deflation reflexes in determining the pattern of breathing. Head later extended Breuer's work, and Kratschmer laid a similar basis for reflexes from the nose and larynx. Then, 50-60 yr later, the development of the thermionic valve and the oscilloscope allowed recording action potentials from single nerve fibers in the vagus. In 1933, Adrian showed that slowly adapting pulmonary stretch receptors were responsible for the inflation reflex. Later, Knowlton and Larrabee described rapidly adapting receptors and showed that they mediated deep augmented breaths and the deflation reflex. Still later, it was established that rapidly adapting receptors were, at least in part, responsible for cough. In 1954, Paintal began his study of C-fiber receptors (J receptors), work greatly extended by the Coleridges. Since approximately 10 yr ago, when the field of this review stops, there has been an explosion of research on lung and airway receptors, many aspects of which are dealt with in other papers in this series.

Pneumocystis jirovecii pneumonia (PJP) is an important opportunistic infection that has been increasingly reported in patients with rheumatic disease. Reported incidence among patients taking TNF inhibitors (TNFi) has varied, but has usually been low. Still, disease causes significant mortality among those affected and must be considered in patients with rheumatological disease presenting with dyspnea and cough. Diagnosis can be difficult in the non-HIV population, and our understanding of the epidemiology and natural history after exposure is changing. Trimethoprim-sulfamethoxazole is believed to be the most effective agent for treatment and prophylaxis, but is associated with significant adverse effects. Given the low incidence reported in most studies of patients on TNFi, prophylaxis is probably not beneficial for this patient population as a whole.

Pneumonia causes substantial morbidity and mortality. Older age, suppressed immune function, and certain drugs increase the risk of community-acquired pneumonia (CAP), whereas adequate dental care and high socioeconomic status decrease the risk. For patients without other significant cardiopulmonary disease, the diagnosis of pneumonia can be straightforward. Common symptoms include fever, chills, pleuritic chest pain, and a cough with mucopurulent sputum. Bacterial and viral infections are the most common etiologies. Fungal and parasitic etiologies are less common. Illness severity scores and new diagnostic methods, including procalcitonin, proadrenomedullin, and bacterial diagnostic testing, are being used increasingly for CAP diagnosis. Antibiotic selection and treatment duration for CAP have become more standardized to decrease rates of bacterial antibiotic resistance. Still, CAP causes significant expense in human life and cost expenditures worldwide.
