Bronchial asthma in childhood is defined as a disease presenting with wheezing, dyspnea and cough on the basis of an inflammatory bronchial hyperreagibility. It is the most common chronic disease in childhood. There are a variety of causes for asthma. Certainly allergy is the most common cause in childhood but also environmental pollution is of importance. Asthmatic attacks, episodes of asthma and asthmatic cough are the most frequent clinical manifestations where as the malignant, hypoxemic asthma crisis is of special importance since its mortality is as high as 0.5-0.8/100,000. Special notice has to be taken on the evaluation of obstructive bronchitis in infancy and childhood which might be very difficult. During the past years, the use of inhalative steroids in the long term treatment has gained increasing importance also in childhood, since it could be demonstrated that side effects of clinical relevance are hardly to be expected.

The impact of HIV infection on Taiwan's tuberculosis epidemic was investigated in a prospective study of all 378 pulmonary tuberculosis patients (mean age, 53.5 years) admitted to the Taiwan Provincial Chronic Disease Control Bureau in 1996. Bacteriologic or pathologic evidence of pulmonary tuberculosis was obtained in 306 cases (81%); the remaining 72 patients had chest radiographs and clinical courses consistent with a tuberculosis diagnosis. In the former group, the sputum smear yielded acid-fast bacilli in 279 patients (73.8%) and sputum cultures grew Mycobacterium tuberculosis in 263 (69.6%). Only 1 patient, an overseas Chinese man with a history of encounters with prostitutes, was HIV-positive. His symptoms included cough, weight loss, and malaise of 4 months' duration. His sputum culture was positive for M. tuberculosis and the chest radiograph revealed diffuse non-cavity infiltration lesions over the bilateral lung parenchyma and mediastinum lymphadenopathy. These findings suggest that the impact of HIV infection on Taiwan's tuberculosis epidemic is not significant at present, in part because HIV remains uncommon. However, continued monitoring of dual infection is essential to guide tuberculosis control efforts.

Pharmacologic therapy is used to prevent and control asthma symptoms, reduce the frequency and severity of asthma exacerbations, and reverse airflow obstruction. Recommendations in this chapter, based on the 1997 National Asthma Education and Prevention Program Expert Panel Report II: Guidelines for the Diagnosis and Management of Asthma, reflect the scientific concept that asthma is a chronic disorder with recurrent episodes of airflow limitation, mucus production, and cough. Asthma medications are categorized into two general classes: long-term-control medications taken daily on a long-term basis to achieve and maintain control of persistent asthma (these medications are also known as long-term preventive, controller, or maintenance medications), and quick-relief medications taken to provide prompt reversal of acute airflow obstruction and relief of accompanying bronchoconstriction (these drugs are also known as reliever or acute rescue medications). Patients with persistent asthma require both classes of medication. Selecting the appropriate pharmacologic therapy to achieve and maintain control of asthma involves several considerations: the medications and their routes of administration, a stepwise approach to managing asthma long-term as a chronic disorder, and the development of an effective clinician-patient partnership strategy where patient education is continuously provided.

Asthma is a common chronic disease that can have a significant impact on individuals' daily lives. It is characterized by wheeze, shortness of breath, chest tightness, and cough secondary to airway inflammation and hyperresponsiveness to a variety of stimuli. Asthma is far more common in boys than girls during early childhood. The prevalence equalizes between the genders during adolescence and then switches to a female predominance in adulthood. This article reviews the epidemiology and possible pathophysiologic mechanisms for the observed differences in asthma between the genders. In practical terms, the impact of asthma may be different according to gender in terms of daily activities for children and adolescents. The implications of gender differences in asthma for the health professional will also be discussed.

Pulmonary lymphangioleiomyomatosis (LAM) is a rare, serious, chronic disease whose etiology is unknown and which affects young women almost exclusively. It produces typical clinical and radiological characteristics. Diagnosis is confirmed on finding histological evidence of irregular proliferation of the smooth muscle cells of the lungs. Treatment is not usually effective and there is rapid worsening of the pulmonary function leading to serious respiratory failure which often results in the patients death. We present two cases of LAM in women, one of whom was 33 and the other 38. In the first case the patient had all the pulmonary findings described in the literature, while the second also had bilateral renal angiomyolipomas. We discuss the histological, radiological and clinical characteristics and evolution of both cases, as well as the treatment given. We also review the literature. It is concluded that LAM should be suspected in young women who have dyspnea, cough and/or hemoptysis and an interstitial radiological pattern, especially when associated with a pleural effusion or pneumothorax.

Thirty-one patients with acute schistosomiasis were evaluated clinically and immunologically. Cytokine levels were determined in peripheral blood mononuclear cell (PBMC) supernatants. Levels of total and antigen-specific IgE, tumor necrosis factor (TNF)-alpha, and immune complexes were measured in serum samples. Clinical findings included general symptoms, liver damage, pulmonary involvement, and pericarditis. All patients had eosinophilia. Immune complexes were detected in 55% of the patients (mean+/-SD, 7.8+/-7.6 microg Eq/mL) and were associated with cough, dyspnea, and abnormal chest radiographic findings. Levels (mean +/- SD) of TNF-alpha (1349.3+/-767.6 pg/mL), interleukin (IL)-1 (2683+/-1270 pg/mL), and IL-6 (382 +/- 52.3 pg/mL) were elevated in PBMC. Serum TNF-alpha levels were elevated in 87% of the patients and were associated with abdominal pain. Higher interferon-gamma levels were detected in PBMC of patients with acute disease than in those of patients with chronic schistosomiasis; IL-5 levels were higher in those with chronic disease. Low IL-5 levels were associated with weight loss. Proinflammatory cytokines and immune complexes with low Th2 responses might explain the immunopathogenesis of acute schistosomiasis.

Mycoplasmas are unique among respiratory pathogens. They possess very small genomes, lack cell walls and are strictly dependent on the host for survival. These pathogens have developed the ability to quickly adapt to the host environment through attachment to target cells within the host. Mycoplasmas have been identified as commensal microbial flora of healthy persons yet, infection of the upper and lower respiratory tracts can result in acute cough, fever and headache, and even chronic disease involving multiple organs. The lung contains a complex system of defense mechanisms with which to combat these pathogens, including innate (nonspecific) and acquired (specific) immune responses. Innate defenses include mechanical clearance, cellular responses provided by host phagocytes and molecular protection in the form of antimicrobial peptides. The interaction of mycoplasmas with different components of the innate immune system and mechanisms by which they incite pathology has proved elusive. The mechanisms by which pathogenic mycoplasmas evade the innate immune system are unknown. The purpose of this review is to summarize current knowledge of these interactions in the hope of identifying new avenues for research and therapy.

Patients with cough may be conveniently divided into those with acute, usually viral, illness and those with chronic cough. Acute cough represents the largest single cause of consultation in primary care, whereas chronic cough is one of the commonest presentations in respiratory medicine. The world-wide market in cough treatments is several billion dollars. In both syndromes, cough sensitivity is upregulated, but the inflammation giving rise to cough is localised to the larynx and large airways in acute cough. Whilst this is also true of cough-predominant asthma, the origin of cough in chronic disease may also lie in the oesophagus, nose or sinuses leading to errors in diagnosis and treatment.

Based on several severe air pollution episodes, a temporal correlation between high concentrations of particulate matter (PM) and SO2 pollution and acute increases in respiratory and cardiopulmonary mortality had been established in Vienna for the 1970's. After air pollution had decreased in Austria in the 1980's--as documented by data on SO2, and total suspended particles (TSP)--no such associations between day-to-day changes of SO2 and TSP and mortality have been documented any more, however, traffic related pollutants like fine particles and NO2 remained a problem. Therefore, short term effects of PM on lung function, morbidity and mortality were investigated in Vienna, Linz, Graz and a rural control area. Long-term exposure and chronic disease--even more important for public health--were studied in repeated cross-sectional, a mixed longitudinal and a birth cohort study on school children in the city of Linz. Lung function growth was found impaired from long-term exposure to air pollutants and improved in districts where ambient air pollution had decreased. Where only TSP and SO2 had decreased, no continuous improvement of small airway function was found and end-expiratory flow rates stayed impaired where NO2-reduction from technical improvements of cars and industry was counterbalanced by increase of motorized (diesel) traffic. Remaining acute effects of ambient air pollution in 2001 from PM, NO2 and co-pollutants found in a time series study also show that continuing efforts are necessary. Active surface of particles inhaled several hours to days before spirometry was found related to short-term reductions in forced vital capacity-FVC (p<0.01), forced expiratory volume in one second-FEV1 (p<0.01) and maximal expiratory flow rate at 50% of vital capacity-MEF50 (p<0.05). In pupils with asthma or previous airway obstruction 4-week-diaries proved that the following symptoms increased with acute exposure to higher active surface of particles: wheezing (p<0.01), dyspnea, cough when going to sleep, cough at night (p<0.05). Efforts to reduce exposure to fine particles from motor traffic and passive smoking have to be increased if we want to achieve full recovery of children from air pollution effects and best respiratory performance in adulthood. Surveillance seems to be necessary not only for particle mass but also for particle number and surface. Little is known on the mechanisms of irreversible long-term effects of PM such as myocardial infarction and cancer. In a prospective cohort study on 1630 dust-exposed and 1630 non dust-exposed workers matched for smoking we found an increase of lung cancer related to nonfibrous insoluble PM. Other studies were able to relate lung cancer to specific particles like those from diesel engines, and a large prospective study of the American Cancer Society was able to link lung cancer in the general population with long-term exposure to fine particles from combustion processes. All these recent epidemiological findings will have consequences for occupational and ambient air PM standards.

Mucormycosis is an extremely rare case of pulmonary mycosis, its prognosis is very poor, and known as an opportunistic infection among immunocompromised hosts accompanied with other primary chronic disease. We report here a case of bilateral lower lobectomies carried out by two-stage operation for pulmonary mucormycosis combined with diabetes mellitus (type I) and severe resistance to an antimycobiotics under biblicographical considerations. A 36-year-old female was diagnosed as a diabetes mellitus (type I), and has been administrated with an insulin injection in 1989 at the age of 22-year-old. The patient was suffered a dry cough in June and the bilateral abnormal shadows were pointed out by the chest X-ray film in November, 2002. By transbronchial lung biopsy, Mucor fungus was confirmed in grannulomatous lung specimen. Intravenous injection of amphotericin B could not be continued due to the unavoidable side-effects from this agent. As the lung mass shadow was enlarged increasing and strongly suggested an abscess, formation in its focus, and then the left lower lobectomy was performed as the first step of surgical treatment and the right lower lobectomy was done on the postoperative forty-fourth day as the second step. The postoperative prognosis was considerably uneventful. After bilateral lower lobectomies, the patient could try a walk and go upstairs with a moderate dyspnea. A possible surgical resection should be conducted for the pulmonary mucormycosis, when the medicinal therapy showed an uneffectiveness and/or an infectious lesion was shown as restricted lesion.
