METHODS: From 2002 to 2005, we interviewed 636 patients and 615 controls from Algeria, Morocco and Tunisia, frequency-matched by centre, age, sex, and childhood household type (urban/rural). Conditional logistic regression was used to evaluate the association of lifestyles with NPC risk, controlling for socioeconomic status and dietary risk factors. RESULTS: Cigarette smoking and snuff (tobacco powder with additives) intake were significantly associated with differentiated NPC but not with undifferentiated carcinoma (UCNT), which is the major histological type of NPC in these populations. As demonstrated by a stratified permutation test and by conditional logistic regression, marijuana smoking significantly elevated NPC risk independently of cigarette smoking, suggesting dissimilar carcinogenic mechanisms between cannabis and tobacco. Domestic cooking fumes intake by using kanoun (compact charcoal oven) during childhood increased NPC risk, whereas exposure during adulthood had less effect. Neither alcohol nor shisha (water pipe) was associated with risk. CONCLUSION: Tobacco, cannabis and domestic cooking fumes intake are risk factors for NPC in western North Africa.

Chest Pub Date Free Form / Volume 126 Issue 2 Start Page 566 Other Pages 581 Notes Place of Publication ISSN/ISBN 0012-3692 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Mycobacterium avium complex (MAC) is ubiquitous. It is found in various freshwater and saltwater sources around the world, including hot water pipes. Although the organism was identified in the 1890s, its potential to cause human disease was only recognized 50 years later. Only a minority of people exposed to the organism will acquire MAC lung disease, usually those with underlying lung disease or immunosuppression. MAC may, however, cause progressive parenchymal lung disease and bronchiectasis in patients without underlying lung disease, particularly in middle-aged and elderly women. Preliminary data suggest that the interferon-Î³ pathways may be deficient in elderly women with MAC lung disease. Other groups of patients who are more likely to harbor MAC in their lungs include patients with a cystic fibrosis or an abnormal Î±1-antiproteinase gene and patients with certain chest wal abnormalities. Treatment results continue to be disappointing, and the mortality of patients with MAC lung disease remains high. A PubMed search identified 38 reports of the treatment of MAC lung disease. Apart from the British Thoracic Society study, the only published controlled investigation, the studies published since 1994 have included a macrolide, either clarithromycin or azithromycin, usually in combination with ethambutol and a rifamycin. If success is defined as eradication of the organism without relapse over a period of several years after treatment has been discontinued, the reported treatment success rate with the macrolide containing regimens is approximately 55%. The prolonged treatment period, side effects, and possibly reinfection rather than relapse are responsible for the high failure rate.

Higher haemagglutination ability of clinical strains for human red blood cells was demonstrated, which could be an expression of their adaptation to the human ecosystem. Environmental strains had higher hydrophobicity, possibly related to adaptation to a low nutritive ecosystem. Expression of lectins was relatively low and comparable in both bacterial populations, but carbohydrate specificities were very different, possibly related to a different implication of these structures in the two ecosystems.

Pub Date Free Form 2004/ Volume 155 Issue 4-Jan Start Page 3 Other Pages 20 Notes Place of Publication ISSN/ISBN 0049-6979 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Antimony (Sb) and Copper (Cu) are two metals of major concern in sewage sludge. Antimony because its use in society is increasing and this might lead to increased Sb concentrations in sludge. Copper because its total volume in use in society is large and because of corrosion from water pipes it is most difficult to reduce the Cu concentrations in sludge. Fresh digested sewage sludge was spiked with Cu or Sb and the sludge was cultivated with oat (Avena sativa), lettuce (Lactuca sativa) or radish (Raphanus sativus). Elutriates from the cultivated sludge were tested for toxicity with Lemna minor (7-d growth) and Daphnia magna (48 h immobility). Before cultivation the elutriates were toxic to Lemna and Daphnia due to high concentrations of ammonia (NH3) and nitrite (NO2-). Cultivation decreased the concentrations of both NH3 and NO2-, thereby reducing the impact of these compounds in the toxicity tests. Cultivation also decreased the metal concentrations and pH. Daphnia magna was the most sensitive test organism in this study with a 48 h EC50 of 1130 mg Cu kg-1 dry wt and 5 mg Sb kg-1 dry wt in elutriates from sludge cultivated with oat. In sludge cultivated with radish the 48 h EC50 was 1700 mg Cu kg-1 dry wt and 22 mg Sb kg-1 dry wt. The effect of Cu could be predicted by pH and Cu concentration in the elutriate, but the effect of Sb could not solely be explained by its concentration in the elutriate.

The samples were collected after water treatment and were analysed for 30 constituents. Although most constituents show wide concentration ranges, Norwegian drinking water is generally soft. The median values obtained are: 0.88 mg Si l-1, 0.06 mg Al l-1, 47 Î¼g Fe l-1, 0.69 mg Mg l-1, 2.9 mg Ca l-1, 3.8 mg Na l-1, 6 Î¼g Mn l-1, 12 Î¼g Cu l-1, 14 Î¼g Zn l-1, 9 Î¼g Ba l-1, 15 Î¼g Sr l-1, 0.14 mg K l-1, 58 Î¼g F- l-1, 6.4 mg Cl- l-1, 11 Î¼g Br- l-1, 0.46 mg NO3- l-1, 5.3 mg SO42- l-1, 2.4 mg TOC l-1, 6.8 (pH), 50 Î¼S cm-1 (conductivity) and 11 mg Pt l-1 (colour). Titanium, Pb, Ni, Co, V, Mo, Cd, Be and Li were seldom or never quantified, due to insufficient sensitivity of the ICP (inductively coupled plasma) method. Norwegian quality criteria, which exist for 17 of the constituents examined, are generally fulfilled, indicating that the chemical quality of drinking water, by and large, is good in Norway. For Fe, Ca, Mn, Cu, pH, TOC and colour, however, the norms for good drinking water are exceeded in more than 9% of the samples, reflecting two of the major problems associated with Norwegian drinking water supplies: (i) many water sources contain high concentrations of humic substances; (ii) in large parts of the country, the waters are soft and acidic, and therefore corrosive towards pipes, plumbing and other installations. Most constituents show marked regional distribution patterns, which are discussed in the light of different mechanisms contributing to the chemical composition of drinking water, namely: chemical weathering of mineral matter; atmospheric supply of salt particles from the sea; anthropogenic pollution (including acid precipitation); corrosion of water pipes and plumbing; water treatment; decomposition of organic matter; and hydrological differences.

Three solvents, tetrahydrofuran, xylene and methylene chloride were evaluated for extraction efficiency. Methylene chloride extracted more than 97% of the total extractable organotin in two extractions and resulted in the highest recoveries of analytes from all three PVC products. Method detection limits ranged from 0.3 to 0.9 Î¼g alkyltin/g PVC. The mean precision of the method is 6.8% relative standard deviation. Food industry PVC product samples contained between <0.8 and 8751 Î¼g/g octyltins and <0.3 and 4.7Î¼g/g butyltins. Butyltins (<0.9-5985 Î¼g/g) were detected in potable water pipe samples. Pipe used in industrial applications contained both butyl- (13-1501 Î¼g/g) and octyltins (701-3033 Î¼g/g).

Pub Date Free Form / Volume 51 Issue 4 Start Page 269 Other Pages 274 Notes Place of Publication ISSN/ISBN 0195-6701 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract We evaluated the efficacy of the ultraviolet irradiation on hospital water colonized by Legionella pneumophila serogroup 3, by inserting a lamp system on a hot water pipe supplying a small area. Cultures were performed for four months from 5 L samples of water, collected before and after the ultraviolet treatment at the lamp unit and from two distal points. Irradiation was effective immediately after disinfection (<10 cfu/L), even when the incoming water was highly contaminated. One distal point showed little or no contamination (<10-20 cfu/L), while the other showed little to moderate contamination (<103 cfu/L). We conclude that ultraviolet irradiation is useful to protect the water system in small area; however, because of the lack of residual activity, it should be combined with other methods of disinfection. Maintenance of the water system is also necessary in order to reduce biofilm formation and Legionella recolonization. Â© 2002 The Hospital Infection Society.
