In October 1989, the Hungarian National Institute of Hygiene initiated the Children's Acute Respiratory Morbidity (CHARM) Surveillance System to assess the association between nine reportable respiratory diseases and air pollution. The weekly number of physician-diagnosed, reportable respiratory diseases among four age groups of children (less than 1, 1-2, 3-5, and 6-14 years) was tabulated for Sopron, a city with 60,000 residents. We calculated the proportion of diseases occurring during weeks with low, moderate, and high sulfur dioxide (SO2) and nitrogen dioxide (NO2) concentrations. The weekly averages of the 24-hour median SO2 concentrations were divided into thirds at less than or equal to 17.6, greater than 17.6 to less than or equal to 26.3, and greater than 26.3 micrograms/m3 (range: 0.9-79.6 micrograms/m3), and the NO2 concentrations at less than or equal to 29.8, greater than 29.8 to less than or equal to 44.1, and greater than 44.1 micrograms/m3 (range: 4.2-90.1 micrograms/m3). During 1990, 11,474 respiratory disease cases occurred among the 4,020 children less than 15 years of age living in Sopron and monitored by the CHARM system. The two most frequently reported disease categories were rhinitis/tonsillitis/pharyngitis (71.5%) and acute bronchitis (8.5%). Sixty-seven percent of pneumonia cases occurred when SO2 concentrations were highest. We found no association between levels of NO2 and respiratory diseases. The CHARM Surveillance System may characterize more fully which groups of children develop particular respiratory diseases following exposure to air pollution.

Ten inpatients at the Second Department of Internal Medicine, Mie University Hospital, developed infections in the course of treatment for hematopoietic disorders and were administered cefoxitin (CFX). Patients suffered from the following infections: pharyngitis, 2; bronchitis, 2; pneumonia, 2; sepsis, 2; bacteremia, 1; suspected cases of bacteremia, 2; and fever of unknown origin, 1. The number of infections totaled 12 as 1 patient with pharyngitis also developed sepsis and 1 patient with pneumonia developed bacteremia. Duration for the administration of CFX ranged between 5 and 18 days with a total dosage of between 30 and 108 g. Of the 10 patients treated with CFX, 9 were treated concomitantly with micronomicin (MCR), doxycycline (DOXY), or sulbenicillin (SBPC), some were treated concomitantly with only 1 of the drugs and some were treated concomitantly with 2 of the drugs. The following clinical results were obtained: Following treatment, 4 patients were considered "excellent", 5, "good", and 3, "poor". Clinical efficacy rate was 75%. Four strains of Gram-positive cocci (1 strain of S. aureus, 2 strains of S. epidermidis and 1 strain of Streptococcus sp.) and 3 strains of Gram-negative rods (2 strains of P. aeruginosa and 1 strain of E. cloacae) were found in the clinical specimens of the 10 patients. These results differed somewhat from reported data that Gram-negative rods such as E. coli, Klebsiella sp., Pseudomonas sp., Serratia sp., are dominant. No serious side effects requiring cessation of treatment were observed. Elevations in the levels of S-GOT, S-GPT, serum alkaline phosphatase, blood urea nitrogen, etc. were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Combustion of liquefied petroleum gas (LPG) can cause indoor air pollution with sulfur dioxide, nitrogen dioxide, total suspended particulate (TSP) and total hydrocarbons. Mice exposed to the pollutant air for three months showed lower ANAE, prolonged sleep time, increased PCE micronucleus in bone marrow, high positivity in Ames test for the lung homogenate and deformity of sperm in males, with obvious dose-response relationship. Investigation on a human population exposed to LPG for more than five years revealed irritating symptoms in respiratory tract, nose and eyes, and prevalence of pharyngitis, rhinitis and conjunctivitis increased significantly. Positive Ames test and micronucleus test in peripheral erythrocytes were detected in concentrated urine samples collected from them. It is postulated this may be associated with the mutagenic pollutants contained in the waste gas emitted by combustion of LPG.

The impact of the environment on the upper respiratory tract of children has become an issue of recent interest. Sulfur dioxide causes nasal congestion in children as well as an increase in both mast cells and lymphocytes in nasal lavage fluids. Chlorpheniramine blocks the effect of sulfur dioxide on the nasal mucosa. Ozone exposure results in nasal congestion, increased levels of histamine, neutrophils, eosinophils, and mononuclear cells in nasal lavage fluid. No data are available on the effects of nitrogen dioxide or wood-burning stoves on the upper respiratory tracts of children. Formaldehyde in sufficient concentrations causes upper airway irritation; however, no data are available on its long-term effects. Detriments in air quality cause adverse changes in the lower respiratory tracts of susceptible individuals. The effects on the upper respiratory tract are more difficult to document. There may be a causal relationship, but definitive proof of whether air pollution results in significant increases in pediatric otitis media, sinusitis, rhinitis, and pharyngitis has yet to be demonstrated.

The effect of welding fumes on small airways was studied in 25 male subjects who welded in aluminium (Al) and to some extent also in stainless steel (SS). Despite a low exposure to welding fumes as compared to the permissible exposure limits, excretion of Al in urine was found to be increased in all subjects (median value: 0.29 mmol/mol creatinine on Friday afternoon, as compared to an upper reference level of 0.10 mmol/mol creatinine). In addition, the welders displayed increased prevalences of work-related eye and airways (pharyngitis and non-specific bronchial hyperreactivity) symptoms, as compared to 25 matched controls. Short-term welders (< or = 2.5 years) had more symptoms related to the upper airways than did long-term welders, which may indicate a selection. Spirometry, closing volume and volume of trapped gas (VTG) did not deviate. However, after methacholine inhalation, the long-term welders had a significantly steeper slope of the alveolar plateau on the single-breath nitrogen wash-out test, and a slight increase in VTG, as compared to the short-term welders and the controls. These findings may indicate a welding fume-induced increase in the reactivity of the small airways. Because Al welding was far more frequent than SS welding, an association with the former seems likely.

Air pollution in all its forms, including sulfur dioxide, ozone, fine particles, carbon monoxide and nitrogen oxides, has resulted in human deaths and diseases worldwide. This article reports on the human suffering caused by air pollution in terms of mortality and morbidity. Based on interviews with scientists, health experts and victims, it is noted that the cities of Thailand, Mexico, Japan, Poland, the Czech Republic, Romania, and the US have the highest levels of air pollution. In these areas people suffer from respiratory illnesses such as pharyngitis, sinusitis, laryngitis, tonsillitis, bronchitis, asthma, flu, and loss of lung function. A most alarming finding indicates that residents of Los Angeles exposed to ozone pollution have double the risk of cancer compared to residents of cleaner cities. Aggravating this situation is the fact that governments often opt to sacrifice human health and lives when forced to choose between protecting the public and shielding industry from pollution regulations.

The azalide azithromycin, which is derived from erythromycin, contains a methyl-substituted nitrogen in the lactone ring. This 15-membered expanded lactone ring results in improved acid stability and oral bioavailability compared with erythromycin. Azithromycin possesses a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including enhanced activity compared with the macrolides against Haemophilus influenzae and Moraxella catarrhalis. In vitro activity of azithromycin against intracellular and clinically atypical pathogens is also good. Azithromycin has a distinct pharmacokinetic profile compared with other antimicrobial agents, the most prominent feature is its high tissue selectivity. Concentrations of azithromycin in respiratory tract, gynaecological tissue and prostate remain above minimum inhibitory concentrations of pathogens for several days, thus making it possible to use a short-course, once-daily dosing regimen. Another feature of azithromycin is that it rapidly penetrates phagocytic cells, with the release of the antibiotics at local sites of infection. Comparative clinical trials have shown that azithromycin given once daily for 3 or 5 days is comparable to comparator drugs given for 7 or 10 days in the treatment of otitis media, sinusitis, pharyngitis, acute bronchitis, acute infectious exacerbations of chronic bronchitis, community-acquired pneumonia and skin and soft tissue infections in adults. Azithromycin given once daily for 3 days has also been shown to be effective in the treatment of respiratory tract and skin and soft tissue infections in children. In addition, some sexually-transmitted diseases are effectively treated by a single 1-g dose of azithromycin; clinical and microbiological responses were comparable to those recorded using doxycycline given twice daily for 7 days. The short-duration, once-daily dosing regimen is well tolerated in adults and children, and there is no evidence of interaction between azithromycin and theophylline, terfenadine, or cimetidine.

Three species of the genus Trollius (Ranunculaceae) are traditionally used to treat upper respiratory tract infections, pharyngitis, tonsillitis, bronchitis, cold with fever, acute tympanitis, aphthae, mouth sore, hemorrhage and pain of gums, acute lymphangitis and acute periostitis. However, only a few studies support its traditional use. These are studies of the biological activity of extracts and/or compounds of selected species of Trollius, but there are no clinical studies proving the effectiveness or possible toxic effects. Until now, the following activity of extracts and/or compounds from certain species of Trollius used in traditional medicine has been proven: antiviral, antibacterial, antiinflammatory and antioxidant. The review showed that flavonoids, mainly C-glycosides, were characteristic of the species Trollius. Furthermore, other main groups of compounds are carotenoids, organic acids, terpenes, alkaloids, sterols, lactones and carbohydrates. The essential oil mainly contains compounds from the group of benzenoids, nitrogen-containing compounds, monoterpenoids and sesquiterpenoids, irregular terpenes and macrocyclic epoxide.

Glutamine is a major dietary amino acid that is both a fuel and nitrogen donor for healing tissues damaged by chemotherapy and radiation. Evidence supports the benefit of oral (enteral) glutamine to reduce symptoms and improve and/or maintain quality of life of cancer patients. Benefits include not only better nutrition, but also decreased mucosal damage (mucositis, stomatitis, pharyngitis, esophagitis, and enteritis). Glutamine supplementation in a high protein diet (10 grams/day) + disaccharides, such as sucrose and/or trehalose, is a combination that increases glutamine uptake by mucosal cells. This increased topical effect can reduce painful mucosal symptoms and ulceration associated with chemotherapy and radiation in the head and neck region, esophagus, stomach and small intestine. Topical and oral glutamine seem to be the preferred routes for this amino acid to promote mucosal healing during and after cancer treatment.
