Iron ion exists in tap water because of dissolution from iron water pipes. Iron ions in tap water cause discoloration and a bad odor. The isotherms of chloroform and iron ion adsorption onto activated carbon fibers in a single solution (chloroform or iron ion) and in a binary mixture solution (chloroform and iron ion) were investigated to estimate the competitiveness between chloroform and iron ions. The amount of adsorbed iron ions increased with increasing pore volume of the activated carbon fibers, while that of chloroform decreased. The amount of chloroform adsorbed onto the activated carbon fibers in the binary mixture solution was greater than that in the single solution. These results indicate that the adsorption of chloroform and iron ion onto activated carbon fibers could be competitive.

To shorten this time and the cost-intensive delays, two different rapid methods for the detection of enterobacteria resp. E. coli and coliform bacteria are used in the laboratory of the municipal water works Mainz. One method is based on an immunological technique detecting Enterobacteriaceae by recognizing the enterobacterial common antigen (ECA). The other method is based on the biochemical determination of different enzymatic reactions specific for E. coli and coliform bacteria. Principal application is the control of processes which require rapid results such as sanitated or newly constructed drinking water pipelines and the verification of disinfection efficiency after fecal contaminations.

The aim of this study was to illustrate the use of the periodontal loss of attachment (LOA) approach in investigating the association between cigarette smoking and loss of periodontal attachment in a convenience sample of adults, in order to determine whether or not smoking was a risk indicator for periodontal disease. All participants were given a detailed periodontal clinical examination in two randomly assigned contralateral diagonal quadrants, with LOA measurements made at six sites per tooth. Information was also collected on participants' socio-demographic characteristics, oral hygiene practices, smoking history, and attitudes towards smoking. The 240 participants examined comprised 81 current smokers (CS), 79 former smokers (FS) and 80 nonsmokers (NS). Substantial differences and a gradient in disease existed for LOA among the three groups. CS exhibited the greatest (and NS the least) prevalence, extent, and severity of LOA. CS had more plaque and calculus than either of the other two groups, but the groups did not differ with respect to bleeding on probing. Overall, smoking was associated with the disease outcome, and this persisted after potential confounders were controlled using multivariate analysis. Although the observed differences may have been due to the self-selected nature of the sample, the gradient evident across the three smoking exposure groups suggests that smoking cessation can slow the progression of the disease. The LOA approach appears to be a versatile and informative method for recording, analysing, and presenting data on periodontitis in epidemiological studies.

The optimal treatment for Barrett's metaplasia and dysplasia is still being debated. The study reported herein was designed to assess the following: (1) the incidence of Barrett's metaplasia among patients with GERD; (2) the ability of laparoscopic fundoplication to control symptoms in patients with Barrett's metaplasia; (3) the results of esophagectomy in patients with high-grade dysplasia; and (4) the character of endoscopic follow-up programs of patients with Barrett's disease being managed by physicians throughout a large geographic region (northern California). Five-hundred thirty-five patients evaluated between October 1989 and February 1997 at the University of California San Francisco Swallowing Center had a diagnosis of GERD established by upper gastrointestinal series, endoscopy, manometry, and pH monitoring. Thirty-eight symptomatic patients with GERD and Barrett's metaplasia underwent laparoscopic fundoplication. Eleven other consecutive patients with high-grade dysplasia underwent transhiatal esophagectomies. Barrett's metaplasia was present in 72 (13%) of the 535 patients with GERD. The following results were achieved in patients who underwent laparoscopic fundoplication (n = 38): Heartburn resolved in 95% of patients, regurgitation in 93% of patients, and cough in 100% of patients. With regard to transhiatal esophagectomy (n = 11), the average duration of the operation was 339 +/- 89 minutes. The only significant complications were two esophageal anastomotic leaks, both of which resolved without sequelae. Mean hospital stay was 14 +/- 5 days. There were no deaths. The specimens showed high-grade dysplasia in seven patients and invasive adenocarcinoma (undiagnosed preoperatively) in four (36%). These results can be summarized as follows: (1) Barrett's metaplasia was present in 13% of patients with GERD being evaluated at a busy diagnostic center; (2) laparoscopic fundoplication was highly successful in controlling symptoms of GERD in patients with Barrett's metaplasia; (3) in patients with high-grade dysplasia esophagectomy was performed safely (invasive cancer had eluded preoperative endoscopic biopsies in one third of these patients); and (4) even though periodic endoscopic examination of Barrett's disease is universally recommended, this was actually done in fewer than two thirds of patients being managed by a large number of independent physicians in this geographic area.

Pub Date Free Form 1999/ Volume 107 Issue 6 Start Page 441 Other Pages 446 Notes Place of Publication ISSN/ISBN 0091-6765 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Copper is an essential trace element that may cause intoxication if intake becomes excessive. Young children are at risk of intoxication because of high consumption of drinking water and immature copper metabolism. The aims of this prospective study were to estimate concentrations of copper in drinking water, volumes of drinking water consumed by children, and children's daily intake of copper. Concentrations of copper in unflushed drinking water were analyzed for 1178 children living in Uppsala and Malmo, Sweden, and concentrations and amounts of copper consumed from drinking water were estimated for 430 of these children, 9-21 months of age. The study children were from Swedish families, were not enrolled in publicly provided day care, and were not breast-fed more than three times a day. In the initial population, the 10th percentile for copper concentration in unflushed drinking water was 0.17 mg/L, the median was 0.72 mg/L, and the 90th percentile was 2.11 mg/L. In the subpopulation of 430 children, the 10th percentile for daily intake of copper from drinking water was 0.03 mg/L, the median was 0.32 mg/L, and the 90th percentile was 1.07 mg/L. The median daily intake of copper from drinking water was higher in Uppsala, at 0.46 mg, than in Malmo, at 0.26 mg. For groups of children,whose families took part in a later prospective diary study, the copper concentration in consumed water could, to some extent, be predicted from the concentration of copper in unflushed drinking water. The lowest concentrations of copper in drinking water were found in households with old water-pipe systems and in those living in detached houses. A large proportion of the young children satisfied their daily requirement of copper solely from drinking water. About 10% of the children had a copper intake above the level recommended by the World Health Organization.

Undersea Hyper Med 1999.; 26(2):61-65.--Diving incidents with symptoms of decompression sickness (DCS) and/or arterial gas emboli (AGE) might increase the degree of pathologic change in the electroencephalogram (EEG) or magnetic resonance imaging (MRI) of the supraspinal central nervous system (CNS). Diving itself, even without known symptoms of DCS and/or AGE, has been proposed to increase the number of CNS lesions using either EEG or MRI. In the first part of a two-part study we examined the effects of recompression treatment on EEG in decompression incidents in a group of sport and professional divers compared with a control group of healthy naval divers. In the second part we recorded brain MRI from three groups of volunteers: 1) divers who were treated for DCS in pressure chamber, 2) divers who had never had symptoms of DCS (and/or AGE), and 3) healthy normal controls who were not divers. Our results indicate that DCS increases the incidence of pathologic EEG recordings, whereas recompression treatment decreases them. The results of MRI do not verify evidence of increased numbers of CNS lesions in normal divers as compared to non-diving, healthy control subjects, whereas some of the divers treated for DCS in a pressure chamber had hyperintense lesions in brain white matter. None of them had any abnormalities in EEG, neurologic performance, or psychologic behavior. Both EEG and MRI are sensitive and non-specific methods for judging suspected evidence of brain lesions from diving or diving accidents.

These products represent a source of bacterial diversity that cannot be accurately analysed using classical phenotypic and biochemical tests. In the present work, the identification and the molecular diversity of lactic acid bacteria isolated from cassava sour starch fermentation were assessed by using a combination of complementary molecular methods: Randomly Amplified Polymorphic DNA fingerprinting (RAPD), plasmid profiling, hybridization using rRNA phylogenetic probes and partial 16S rDNA sequencing. The results revealed a large diversity of bacterial species (Lb. manihotivorans, Lb. plantarum, Lb. casei, Lb. hilgardii, Lb. buchneri, Lb. fermentum, Ln. mesenteroides and Pediococcus sp.). However, the most frequently isolated species were Lb. plantarum and Lb. manihotivorans. The RAPD analysis revealed a large molecular diversity between Lb. manihotivorans or Lb. plantarum strains. These results, observed on a rather limited number of samples, reveal that significant bacterial diversity is generated in traditional cassava sour starch fermentations. We propose that the presence of the amylolytic Lb. manihotivorans strains could have a role in sour starch processing.

The lack of an aqueduct and a sewerage system was an impairment to progress. For nearly forty years (1890-1930) these problems have caused a myriad of medical discourses formulated by scientists, technicians and politicians. Cartagena's contribution to solve the sanitation problem in cities has consisted in making use of engineers' knowledge. The construction of urban facilities in the beginning of the twentieth century required a more technical knowledge, one which would advance a comprehensive solution to the water problem, ensure sufficient supply and efficient drainage. Thus, in the last turn of the century, the medical doctor is no longer the only authoritative voice when it comes to the management of urban life. The construction works which require an engineer, involving him in public health, have drawn a distinction between "hygiene" and "sanitary science".
