The government has been trying to improve the situation by encouraging the use of rainwater and piped water. This study aimed to document the change of water use and to identify factors associated with safe water use in 1997 compared to that in 1994. Home visits and face-to-face questionnaire interviews were undertaken. Information on water use for drinking, cooking, washing food and washing utensils in 1994 and 1997 was obtained. Among 3,849 households from which data could be obtained (estimated 79% of total households), the percentages of using safe water (including water from bottled rain water, piped and artesian well water) for drinking and cooking rose from 72.5 and 57.9 in 1994 to 93.6 and 80.9 in 1997, respectively. The percentages for washing foods and for washing utensils rose from 28.6 and 20.5 to 59.1 and 53.8, respectively. In 1997, percentage of households using piped water for drinking and cooking was still low (3.6 and 12.3) compared to those using piped water for washing food and utensils (39.1 and 43.6). Multivariate analysis shows that independent factors of the household predicting safe water use are: high arsenic area, near main road and having piped water installed. The influence of these factors (as judged by the level of odds ratio) operates more or less equally on water use for all purposes, except that installation of piped water has more influence on washing water than drinking and cooking water. We conclude that safe water supply in the area is still inadequate. Even if piped water is installed, it is often not used for drinking and cooking. The reasons for not using piped water for drinking and cooking need to be identified.

They are widely used as a traditional oral hygiene tool in several African and Middle Eastern countries. The aim of this study was to assess and compare the periodontal status of adult Sudanese habitual miswak and toothbrush users. The study population comprised male miswak users (n = 109) and toothbrush users (n = 104) with age range 20-65 years (mean 36.6 years) having 18 or more teeth present. They were recruited among employees and students at the Medical Sciences Campus in Khartoum, Sudan. One examiner used the Community Periodontal Index (CPI) to score gingival bleeding, supragingival dental calculus, and probing pocket depth of the index teeth of each sextant. In addition, the attachment level was measured, which, along with the CPI, was used to assess the periodontal status of the two test groups. Gingival bleeding and dental calculus were highly prevalent in the study population. Approximately 10% of the subjects had > or =4 mm probing depth and 51% had > or =4 mm attachment loss in one or more sextants. Subjects in the age group 40-65 years had a significantly (p or =4 mm probing depth and attachment loss than the 30-39 years group. Miswak users had significantly (p or =4 mm probing depth and higher > or =4 mm attachment loss as well as a tendency (p = 0.09) to lower gingival bleeding in the posterior sextants than did toothbrush users. These differences were not significant in the anterior sextants. It is concluded that the periodontal status of miswak users in this Sudanese population is better than that of toothbrush users, suggesting that the efficacy of miswak use for oral hygiene in this group is comparable or slightly better than a toothbrush. Given the availability and low cost of miswak, it should be recommended for use in motivated persons in developing countries.

STUDY DESIGN/MATERIALS AND METHODS: Bovine enamel was prepared either by acid or laser etching and divided into four experimental groups, either acid or laser-etched teeth with or without a primer. A gelatin capsule was used to place the sealant on the prepared enamel surface and the bond tested in shear. Also surface roughness was evaluated by using a surface analyzer and an atomic force microscope. RESULTS: Shear bond strength results were the following: acid etch = 8.8 +/- 3.8 MPa, acid etch with primer = 10.3 +/- 5.5 MPa, laser etch = 4.0 +/- 1.1 MPa, and laser etch with primer = 6.2 +/- 2.3 MPa. Analysis of variance statistical analysis found no significant difference in bond strength between the acid-etched groups. However, the laser-etched groups had significantly lower bond strengths from the acid-etched teeth. In addition, a significant difference was observed between the laser-etched groups, where the use of the primer helped to increase the bond strength of the sealants. The surface roughness was significantly greater on the laser-etched teeth at the microm level (by using a surface analyzer) from the acid-etched and the control specimens. No difference in roughness (by using an atomic force microscope) was observed at the nanometer level between the laser and acid-etched teeth. CONCLUSION: For these particular settings, the laser-etched teeth resulted in lower bond strengths to enamel and the use of a primer increased the bond strength for laser-etched teeth only.

Data about tobacco use and other health risk behaviors were analyzed from the 1997 national Youth Risk Behavior Survey implemented by the Centers for Disease Control and Prevention. One-fourth of students (24%) reported current use of a single tobacco product (i.e., cigarettes, smokeless tobacco, or cigars during the 30 days preceding the survey), and 19.5% reported currently using more than one tobacco product. Generally, students who reported current tobacco use also reported engaging in other substance use, intentional injury risk behaviors, and sexual risk behaviors. For many risk behaviors, these results were especially pronounced among students who reported using two or all three tobacco products. Programs designed to prevent tobacco use should consider that such use often occurs concomitantly with other health risk behaviors.

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.

Of 40 divers who performed 53 open water dives after being tested for a patent foramen ovale (PFO), arterial gas emboli were detected in 7 of 13 dives, which resulted in venous bubbles. In five of these seven dives, there was evidence of a PFO by contrast transcranial Doppler sonography, indicating an increased risk of arterializing venous bubbles in divers with a PFO.

The results of limited longitudinal studies are controversial. OBJECTIVE: To assess the nature and direction of the relationship between cigarette smoking and depression among teens. DESIGN: Prospective analysis of baseline and 1-year follow-up data from the National Longitudinal Study of Adolescent Health. SETTING: In-home teen and parent interviews. PARTICIPANTS: Two samples were identified. For the first sample, 8704 adolescents who were not depressed at baseline based on CES-D scores were identified for analyses of the effects of cigarette smoking on development of high depressive symptomatology. Baseline smoking status, which could vary in this group, was the predictor of interest in these analyses. For the second sample, 6947 teens who had not smoked cigarettes in the 30 days before the baseline survey (noncurrent smokers) were identified for analyses on the effect of high depressive symptoms on subsequent moderate to heavy cigarette use at 1 year of follow-up. Baseline high depressive symptomatology based on CES-D score was the predictor of interest in this sample. MAIN OUTCOME MEASURES: Among the nondepressed, developing high depressive symptoms at 1 year of follow-up. Among noncurrent smokers, smoking at least 1 pack per week at 1 year of follow-up. RESULTS: For the nondepressed, multivariate modeling revealed that current cigarette smoking was the strongest predictor of developing high depressive symptoms in all models (final model odds ratio [OR]: 3.90; 95% confidence interval [CI]: 1.85,8.20). For noncurrent smokers, although in bivariate analyses, baseline high depressive symptoms increased the risk of heavy smoking nearly threefold, multivariate modeling revealed that baseline high depressive symptoms were not predictive of heavy smoking when controlling for other determinants of smoking in teens. Previous experimentation with smoking was the strongest predictor of becoming a heavy smoker (OR: 3.04; 95% CI: 1.93,4.88). CONCLUSIONS: In contrast to common dictum, depression does not seem to be an antecedent to heavy cigarette use among teens. However, current cigarette use is a powerful determinant of developing high depressive symptoms.

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".

Surgical series and population-based studies show that, by 1994, adenocarcinomas of the esophagus accounted for half of all esophageal cancer among white men. The causes of this increase in incidence remain to be elucidated. Esophageal adenocarcinomas and a portion of EGJ adenocarcinomas arise from long and short segments of specialized intestinal metaplasia (Barrett's esophagus). The prevalence of long segments of Barrett's esophagus (> 3 cm) in patients having endoscopy for reflux symptoms is 3%, and 1% in those undergoing endoscopy for any clinical indication. However, a silent majority of patients with Barrett's esophagus remain unrecognized in the general population and may not be diagnosed unless adenocarcinoma develops. Recent studies document a rise in the diagnosis of specialized intestinal metaplasia of the cardia. Nearly all these patients have associated carditis, and Helicobacter pylori infection has been linked to this condition. The possible origin of EGJ adenocarcinomas in the sequence carditis--specialized intestinal metaplasia needs to be clarified. Smoking and obesity are additional risk factors for adenocarcinoma of the esophagus and EGJ. Current data does not confirm H. pylori as a risk factor for cancer of the EGJ.
