Esophageal adenocarcinoma, once an uncommon entity, has been growing rapidly in incidence over the last two decades in several parts of the world. Barrett's esophagus is a change in the esophageal epithelium of any length that can be recognized at endoscopy and is confirmed to have intestinal metaplasia by biopsy (American College of Gastroenterology guidelines). Because of its premalignant nature, it is recommended that patients with BE undergo regular endoscopic surveillance. The recommendation for endoscopic surveillance is based on unproved and controversial assumptions including: 1) the assumption that Barrett's esophagus adversely influences survival; 2) the assumption that endoscopic surveillance can reliably detect early, curable neoplasia in the columnar lined esophagus. Moreover, the low incidence of adenocarcinoma (reported cancer incidence rates in prospective studies on BE range between 0.5% and 1.9%) is used to support an approach of not surveying patients with Barrett's esophagus. Despite these not convincing data, endoscopic surveillance is considered ''reasonable'' and ''desirable'' by the gastroenterological associations and consensus meetings. Endoscopic surveillance for cancer in Barrett's esophagus (BE) is performed primarily to seek dysplasia, to prevent the progression to invasive malignancy; however, one of the limitations of using dysplasia is a lack of understanding of its natural history. The efficacy of endoscopic surveillance for Barrett's esophagus is likely to remain unclear for a long time. The American College of Gastroenterology has recommended the following practice guidelines: a) for patients with no dysplasia, surveillance endoscopy is recommended at an interval of every 2 to 3 years; b) for patients with low grade dysplasia, surveillance endoscopy every 6 months for the first year is recommended, followed by yearly endoscopy if the dysplasia has not progressed in severity; c) for patients with high grade dysplasia, two alternatives are proposed after the diagnosis has been confirmed by an expert gastrointestinal pathologist. One alternative is intensive endoscopic surveillance until intramucosal cancer is detected at an interval of every 3-6 months. The other alternative is esophageal resection. In the situation of indeterminate dysplasia, whereas the pathologist can not come to definite diagnosis, control biopsies are proposed after 2 months of adequate acid suppression by means of proton pump inhibition. In all cases, the technique of random, four quadrant biopsies taken every 2 cm in the columnar-lined esophagus for standard histologic evaluation is recommended. Any grossly abnormal areas may be biopsied too. One can expect however that during the next future these protocol will change considering new data on dysplasia detection (biochemical markers, flow cytometry), new techniques to identify dysplasia (chromoendoscopy, endosonography, coherence optical tomography, fluorescence techniques) and development of better ablative techniques. At present a marker other than dysplasia identifying a high risk group for cancer on which to focus endoscopic surveillance has not yet been established.

Pub Date Free Form / Volume 66 Issue 5 Start Page 633 Other Pages 638 Notes Place of Publication ISSN/ISBN 0002-9637 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract This investigation's objective was to identify risk factors for hepatitis C virus (HCV) in a village in Upper Egypt with a moderately high prevalence (8.7%) of antibodies to HCV (anti-HCV). A representative sample of 6,012 (63%) of the 9,581 village inhabitants was included in the study. A questionnaire solicited information regarding risk factors for infection, and blood samples were tested for anti-HCV. Parenteral risks identified in age-adjusted analysis included blood transfusions, dental procedures, hospital admission, surgery, complicated deliveries, history of injection therapy for schistosomiasis, and history of frequent injections. Circumcision was pervasive and was not associated per se with ant-HCV; however, circumcision by an informal, rather than formal, health care provider was associated with anti-HCV among young men and boys. The results did not reveal any unique community-acquired exposures that caused HCV infections: inhabitants who had tattoos, who smoked goza, who were shaved by a community barber, or who had their ears pierced were not at greater risk for anti-HCV than those who did not. Risks identified in multivariate analysis for both those older and younger than 30 years included prior parenteral therapy for schistosomiasis and blood transfusion; for those 30 or younger, circumcision by an informal rather than formal health care provider, and frequent injections; and for those older than 30, never attending college, invasive medical procedures, and complicated deliveries. Selecting for those with blood transfusion, prior parenteral therapy for schistosomiasis, and invasive medical procedures would identify less than half of those infected. Inclusion of frequent injections would identify 80% of those infected with HCV, but as a result of the pervasive use of injections, it would not discriminate from those uninfected. Nonetheless, general reduction of these exposures and assuring sterile practices are logical goals for intervention.

Furthermore, the relationship of these behaviours with road traffic accidents was examined. A total number of 1126 Finnish drivers completed a questionnaire containing the Driver Behaviour Questionnaire (DBQ) with extended violations scale, and questions regarding background information, such as age, gender and mileage. Also, questions about previous accidents and fines were asked. Factor analysis showed that a four-factor structure seemed more appropriate than the earlier established three-factor structure. The four factors were errors, lapses, speeding violations and interpersonal violations. The two types of violations result from different motives, and seem to be associated with different kinds of affect. Both interpersonal and speeding violations were reported most by young males, which was consistent with earlier findings. Logistic regression analyses indicated that errors predicted active accident involvement after partialling out the effects of demographic variables, whereas interpersonal violations were positively related to involvement in passive accidents. This was presumably due to different reporting tendencies of respondents. Speeding tickets were predicted by speeding and interpersonal violations and lapses and penalties for speeding by both kinds of violations and errors. Penalties for speeding, parking and other offences were predicted by interpersonal violations. The implications of these results are discussed.

It has been speculated that gingival bleeding may be influenced by several independent factors other than plaque. Great intra- and interindividual variation of gingival thickness and width has been reported. Based on respective observations, the existence of different gingival phenotypes has been suggested. The aim of the present study was to investigate the possible influence of gingival thickness and width on bleeding on probing. Forty young adults with mild, plaque-induced gingivitis, 24 non-smokers and 16 smokers, participated in this cross-sectional study. In addition to periodontal probing depth, clinical attachment loss, width of gingiva, bleeding on probing, and presence of plaque, gingival thickness was measured with an ultrasonic device. Multivariable models were separately calculated for buccal, mandibular lingual, and palatal surfaces and generally adjusted for tooth type. Generalised Estimation Equation methodology was employed in order to adjust for correlated observations. Plaque was significantly associated with bleeding upon probing only at buccal sites (odds ratio 1.80, 95% confidence interval 1.19-2.72) An influence of similar magnitude was identified for smoking (odds ratio 1.76; 1.07-2.89). At lingual sites in the mandible, bleeding was influenced by smoking (odds ratio 2.25; 1.18-4.25) and gingival thickness (odds ratio for thick gingiva >1 mm of 1.93; 1.02-3.65), but not plaque. At palatal sites, only periodontal probing depth had an influence (odds ratio 1.89; 1.25-2.84). It was concluded that, apart from supragingival plaque, smoking was an independent risk factor for gingival bleeding on probing. Thin and vulnerable gingiva of insufficient width was not more likely to bleed after probing than thicker tissue.

The major aims of the present study were to investigate site-specific associations between plaque and gingivitis as well as transition dynamics of naturally occurring gingivitis in smoking and non-smoking young adults. METHODS: 65 systemically healthy young adults, 19 to 30 years old, participated. 33 volunteers smoked at least 20 cigarettes per day, whereas 32 subjects were non-smokers. Clinical periodontal conditions were assessed four times within a time period of 6 months. An ecological approach in data analysis as well as site-specific analyses considering the correlated structure of data were performed. RESULTS: At the outset and after 6 months, smokers had significantly more supragingival plaque than non-smokers. At the final examination, bleeding upon probing as well as calculus were more prevalent in smokers. A site-by-site analysis revealed that smokers tended to have a weaker association between supragingival plaque and bleeding on probing than non-smokers (median Mantel-Haenszel's common odds ratio 1.91 vs. 2.89, p=0.07). Multiple logistic regression analyses adjusted for periodontal probing depth, plaque and calculus identified smoking status to significantly increase the risk for the first transition of non-bleeding to bleeding upon probing by 86% (p<0.01). In contrast, recovery of bleeding sites was positively influenced by female gender, but not smoking. CONCLUSIONS: In multivariate analyses adjusted for probing depth, plaque and calculus, smokers appeared to be at higher risk for the transition from non-bleeding to bleeding on probing. Weaker associations between plaque and naturally occurring gingivitis in smokers may have important consequences for preventive strategies for gingivitis.

We conducted a case-control study to identify the possible risk of indoor smoke and biomass combustion. We compared 100 chronic bronchitis cases with 100 age-matched controls. The odds ratio OR] was used as the basic statistic to evaluate risk. Chronic bronchitis was associated with cigarette smoking OR=6.10; p=0.009], water-pipe smoking OR=4.41; p=0.014], household baking OR=4.90; p=0.002], using wood for baking OR=3.04; p=0.000], using wood for space heating OR=2.36; p=0.009], using wood for cooking OR=7.17; p= 0.000], and using kerosene fuel for cooking OR= 4.63; p=0.000]. Results have revealed that among women in Chahar- Mahal- Bakhtiari, wood and other biomass fuels used for cooking, baking and heating are associated with chronic bronchitis.

PFO and RLS through the atrial chambers have been recently studied in a number of conditions not or marginally related to cerebrovascular disease. Historically the first studies addressed the presence of RLS in scuba divers as a possible abnormality related to decompression sickness (DS) of unknown aetiology. Despite initial debate there is now robust evidence to claim that patency of foramen ovale increases the risk of developing DS by two and half to four times. Patients with PFO-related DS tend to have early occurrence of symptoms after surfacing and a clinical presentation that indicates brain or upper cervical spinal cord involvement. Recent reports suggest that divers with hemodynamically significant RLS may have an increased risk of developing clinically asymptomatic multiple brain lesions. PFO has been found in patients suffering from migraine with aura with approximately the same frequency as that encountered in cryptogenic stroke patients. This finding has prompted speculations on the possible role of RLS in increasing the stroke risk in migraineurs and in the pathophysiology of the aura. Recent reports showing that migraine with aura is dramatically improved after transcatheter closure of PFO suggest that migraine with aura may indeed be triggered by humoral factors that reach the brain by escaping the pulmonary filter. A RLS is involved in a rare condition known as platypnea-orthodeoxia and perhaps underlies an increased risk of cerebral complications after major orthopedic surgery. Valsalva-like activities often precede the occurrence of attacks of transient global amnesia (TGA) and abnormalities consistent with hypoperfusion of deep limbic structures have been reported during a typical TGA episode. This had raised the hypothesis that TGA may be triggered by paradoxical embolism of platelets aggregates in the posterior circulation, but the search for an increased frequency of PFO in TGA patients has yielded conflicting results. Conditions that determine an increase in pulmonary pressure may facilitate the opening of the virtual interatrial valve and thus promoting shunting of blood to the left heart chambers which in turn might contribute to further desaturation of arterial blood. It is therefore not surprising that RLS has been found in 70% of patients with chronic obstructive pulmonary disease and increased pulmonary pressure and in the same proportion of patients with obstructive sleep apnoea, a condition that ultimately may result in pulmonary hypertension. In conclusion, from the evidence gathered so far the picture is emerging of an important role of PFO in a number of non-stroke conditions, either as causative factor or as associated condition predisposing to complications. The availability of simple diagnostic techniques such as transcranial Doppler (TCD) to assess RLS will undoubtedly contribute a great deal of knowledge on the relevance in medicine of this hitherto neglected condition.

Fifteen sound third molars were randomly assigned to three groups. The mesial and distal surfaces were flattened and covered using adhesive tape with a central orifice delimiting the adhesion area (7.07 mm2). Group I, the enamel surface was conditioned with 37% phosphoric acid for 15 s; group II, the surface was treated using air abrasion with aluminum oxide; group III, the enamel surface was treated using an association of air abrasion with aluminum oxide and 37% phosphoric acid. The Single Bond (3M) adhesive system was applied and a Teflon matrix was placed and filled with composite resin Z-100 (3M) and light-cured. The shear bond strength test was performed with a universal testing machine. The acid etching technique and air abrasion with aluminum oxide associated with acid etching had the highest shear bond strength values. Data were subjected to statistical analysis using ANOVA and the Turkey test, and no statistically significant difference in shear bond strength was observed between group I (12.49 +/- 2.85 MPa) and group III (12.59 +/- 2.68 MPa). In contrast, both groups had statistically better shear bond strengths compared to group II (0.29 +/- 0.56 MPa; p < 0.05). Air abrasion with aluminum oxide does not substitute acid etching. The association of these methods to obtain adequate adhesion to the substrate is necessary.

Here, we describe a patient in which scuba diving is thought to be associated with stroke in a subject with an otherwise clinically silent PFO. During a rapid ascent a 43-year-old-scuba diver reported weakness and paresthesias in the right arm which lasted about 10 min. He presented similar symptoms 2 days later 1 h after diving, and a third time on his flight back home. The MRI showed multiple hyperintense areas on T2-weighted images in the white matter. Transoesophageal echocardiography (TEE) showed a PFO, whilst all haematological and haemocoagulation tests were negative. Scuba diving may constitute a patho-physiological condition in the presence of PFO as breath-holding promotes right-to-left shunt and arterialization of venous bubbles.

The Doppler ultrasonic detection of circulating venous bubbles after diving is considered a useful index for the safety of decompression because of the relationship between bubbles and decompression sickness risk. The aim of this study was to assess the effects of ascent rate, age, maximal oxygen uptake (VO(2 max)), and percent body fat on the production of bubbles after diving. Fifty male recreational divers performed two dives at 35 m during 25 min and then ascended in one case at 9 m/min and in the other case at 17 m/min. They performed the same decompression stops in the two cases. Twenty-eight divers were Doppler monitored at 10-min intervals, until 60 min after surfacing, and the data were analyzed by Wilcoxon signed-rank test to compare the effect of ascent rate on the kinetics of bubbles. Twenty-two divers were monitored 60 min after surfacing. The effect on bubble production 60 min after surfacing of the four variables was studied in 47 divers. The data were analyzed by multinomial log-linear model. The analysis showed that the 17 m/min ascent produced more elevated grades of bubbles than the 9 m/min ascent (P < 0.05), except at the 40-min interval, and showed relationships between grades of bubbles and ascent rate and age and interaction terms between VO(2 max) and age, as well as VO(2 max) and percent body fat. Younger, slimmer, or aerobically fitter divers produced fewer bubbles compared with older, fatter, or poorly physically fit divers. These findings and the conclusions of previous studies performed on animals and humans led us to support that ascent rate, age, aerobic fitness, and adiposity are factors of susceptibility for bubble formation after diving.
