In this study, the authors investigated the possible relationship between environmental-including dietary-factors and respiratory and ear infections in children. A sample of 304 children, aged 4-5 y, in Geneva, Switzerland, was studied. Mothers filled out a questionnaire that the authors provided. The questionnaire included items on food frequency, infections, and background factors (e.g., education, housing conditions, parents' smoking habits). Allergy was a risk factor for all infections, and mother's age was a protective factor. Humid conditions at home was a significant risk factor for cold, sore throat, and otitis (odds ratios = 2.71, 3.03, and 2.77, respectively); mold in the home was a significant risk factor for otitis (odds ratio = 2.80); and attending day-care centers was a significant risk factor for cold and bronchitis (odds ratios = 1.36 and 1.89, respectively). Dietary factors were not related to disease risk nor were environmental tobacco smoke or housing conditions generally related to an increased risk.

The need to decrease excess antibiotic use in ambulatory practice has been fueled by the epidemic increase in antibiotic-resistant Streptococcus pneumoniae. The majority of antibiotics prescribed to adults in ambulatory practice in the United States are for acute sinusitis, acute pharyngitis, acute bronchitis, and nonspecific upper respiratory tract infections (including the common cold). For each of these conditions-especially colds, nonspecific upper respiratory tract infections, and acute bronchitis (for which routine antibiotic treatment is not recommended)-a large proportion of the antibiotics prescribed are unlikely to provide clinical benefit to patients. Because decreasing community use of antibiotics is an important strategy for combating the increase in community-acquired antibiotic-resistant infections, the Centers for Disease Control and Prevention convened a panel of physicians representing the disciplines of internal medicine, family medicine, emergency medicine, and infectious diseases to develop a series of "Principles of Appropriate Antibiotic Use for Treatment of Acute Respiratory Tract Infections in Adults." These principles provide evidence-based recommendations for evaluation and treatment of adults with acute respiratory illnesses.This paper describes the background and specific aims of and methods used to develop these principles. The goal of the principles is to provide clinicians with practical strategies for limiting antibiotic use to the patients who are most likely to benefit from it. These principles should be used in conjunction with effective patient educational campaigns and enhancements to the health care delivery system that facilitate nonantibiotic treatment of the conditions in question.

Despite the lack of evidence of efficacy of antibiotic agents for treating upper respiratory tract infection (URI) symptoms (i.e., acute cough, sore throat, purulent nasal discharge, bronchitis, and the common cold), primary care providers frequently prescribe antibiotic agents for patients presenting with such symptoms. Far from being a harmless practice, prescribing antibiotics for conditions for which there is no proven benefit of such therapy contributes to a number of adverse consequences, including the development of antimicrobial resistance and an unnecessary expense to patients and the healthcare system as a whole. An evidence-based approach to practice can guide nurse practitioners in making the best clinical management decisions for patients presenting with URI symptoms.

The role of eosinophilic airway inflammation in the variant asthma syndromes of cough and chest colds is not well defined. We tested the hypothesis that children with persistent cough and chest colds have increased sputum eosinophils, similar to those with wheeze. The parents of 390 primary school children completed a symptoms questionnaire. Children with wheeze (n = 28), cough (n = 12), recurrent chest colds (n = 17), and no symptoms (control subjects, n = 26), underwent allergy skin prick tests, spirometry, hypertonic saline inhalation challenge, and sputum induction, and then completed a peak expiratory flow (PEF) and symptoms diary over a 2-mo period. Children with wheeze had significantly reduced PEF (p = 0.001) and higher sputum eosinophils when compared with the cough, chest cold, and control groups (3.1% versus 0.5%, 0%, 0%; p = 0.03). The prevalence of eosinophilic bronchitis (sputum eosinophils > 2.5%) was 45% in the wheeze group, which was significantly higher than the control group (9.35%, p = 0.04). Eosinophilic bronchitis was present in two children with cough (20%) and two with chest colds (15%, p > 0.05 versus control). In these groups, eosinophilic bronchitis was not associated with airway hyperresponsiveness (AHR) to hypertonic saline (p > 0.05). Children with cough and chest colds reported greater exposure to environmental tobacco smoke. In conclusion, this community-based survey of children with chronic respiratory symptoms has shown that wheeze is a good discriminator for the presence of eosinophilic bronchitis, and that persistent cough and recurrent chest colds without wheeze should not be considered a variant of asthma. Eosinophilic bronchitis did occur in a significant minority of these "variant asthma" syndromes.

The prevalence of asthma, bronchial hyperresponsiveness (BHR) and allergic rhinitis in children was lower in East Germany compared to West Germany. The reasons for this difference are still not understood. This study tested the hypothesis that prevalence of BHR increased in East German children after reunification. Two consecutive cross-sectional surveys of schoolchildren aged 8-14 yrs from three communities in East Germany were carried out in 1992-1993 and 1995-1996. A subsample of 530 and 790 children with complete lung function and cold air challenge data was analysed. The prevalence of BHR increased from 6.4%, in 1992-1993 to 11.6% in 1995-1996 (odds ratio (OR): 2.0, 95% confidence interval (CI): 1.3-3.0, adjusted for age, sex, season, community and parental education). No changes were found for asthma, allergic rhinitis or allergic sensitization. In contrast, physician diagnosed bronchitis, pneumonia and frequent colds decreased significantly. The observed increase in the prevalence of BHR was reduced (OR: 1.5, 95% CI: 0.95-2.3) after adjustment for several indoor factors. In conclusion, while the prevalence of nonallergic respiratory diseases seems to decrease, the prevalence of bronchial hyperresponsiveness might be a first indicator of the suspected increase of asthma prevalence in East Germany. The present results give indirect evidence, that less respiratory infections may be associated with higher bronchial hyperresponsiveness.

Respiratory illnesses are the commonest cause of patient visits to physicians. Although the common cold, sinusitis and bronchitis may be lacking in drama, they account for a substantial amount of morbidity among women of reproductive age and are frequently encountered by physicians caring for pregnant women. Present knowledge about the management of these common conditions and the safety of the medications often used to treat them are reviewed in this chapter. Asthma and community-acquired pneumonia are more serious respiratory illnesses that are also often encountered in pregnancy. Present evidence suggests that community-acquired pneumonia is best treated empirically, with additional investigation usually necessary only if there is a failure of initial treatment. The recognition of asthma as an inflammatory condition has led to a very specific approach to its management that can readily and safely be applied to the pregnant woman. Treatment of HIV and tuberculosis should not be withheld during pregnancy because of the life-threatening nature of these infections and the importance of preventing vertical transmission.

In the light of the theory of treating the internal disease externally, an externally used plaster for treating cough and dyspnea due to acute bronchitis (Ke Chuan Yi Tie Kang [symbol: see text]-[symbol: see text]) was successfully applied to 735 cases of acute bronchitis (the treatment group), with the other 423 cases treated with routine western drugs as controls. The results showed that the cure rate in the treatment group was significantly higher than that in the control group (P < 0.01); and that in the treatment group, the cure rate for the wind-cold type of acute bronchitis was significantly higher than that for the wind-heat type of acute bronchitis (P < 0.01).

The herb, Chrysanthemum zawadskii var, latilobum commomly known as Gu-Jul-Cho in Korea, used in traditional medicine to treat pneumonia, bronchitis, cough, common cold, pharyngitis, bladder-related disorders, gastroenteric disorders, and hypertension. Linarin is the main active compound and the biological mechanisms of its activity are unclear. It is believed that effects of this herb may be exerted through the pluripotent effectors of linarin due to its ability to treat a variety of afflictions. In this study, the effects of linarin on the mouse macrophages cell line, RAW 264.7, were investigated. It was found that linarin could activate macrophages by producing cytokines. Monocytes and tissue macrophages produce at least two groups of protein mediators of inflammation, interleukin 1 (IL-1) and the tumor necrosis factor (TNF). Recent studies have shown that TNF and IL-1 modulate the inflammatory function of endothelial cells, leukocytes, and fibroblasts. TNF-alpha production by macrophages treated with linarin occured in a dose dependent manner. However, IL-1 production was largely unaffected by this natural product. This study demonstrated the ability of linarin to activate macrophages both directly and indirectly. Linarin also affect both cytokine production and nitric oxide inhibition, in addition to the expression of some surface molecules. Nitric oxide (NO), derived from L-argin-ine, is produced by two forms(constitutive and inducible) of nitric oxide synthase (NOS). The NO produced in large amounts by inducible NOS is known to be responsible for the vasodilation and hypotension observed in septic shock. Linarin was found to inhibit NO production in the LPS-activated RAW 264.7 cells. Linarin may be a useful candidate as a new drug for treating endotoxemia and the inflammation accompanied by NO overproduction. The linarin-treated total lymphocytes exhibited cytotoxicity in a dose dependent manner between 20 microg/ml and 40 microg/ml. These results suggest that linarin may function through macrophage activation.

The most common health problems in Nghi Trong in Vietnam include reproductive tract infections, children's diseases such as diarrhea, and acute bronchitis. Reproductive tract infections take place because of unsanitary water and acute bronchitis is rampant because of the cold weather. Although no HIV/AIDS cases have been reported in the commune, the Nghi Trong Commune Health Center (CHC) is making every effort to prevent HIV infection while providing other services. Under the Japan International Cooperation Agency (JICA) project, information, education and communication activities have been implemented in the district. These activities are important because they have been helping commune people identify and understand common health problems, how to prevent them, and how to get timely treatment. It is not only temporary, but it is permanently effective in health development. In addition, health staff workers at the CHCs are benefiting from the training program provided by the JICA project. More commune people are also visiting the CHCs for examination and treatment.
