PURPOSE: The aim of the present study was to assess the oral mucosal health status of young male adults (aged 18 to 24 years) in Switzerland and to correlate their clinical findings with self-reported risk factors such as tobacco use and alcohol consumption. MATERIALS AND METHODS: Data on the oral health status of 615 Swiss Army recruits were collected using a standardised self-reported questionnaire, followed by an intraoral examination. Positive clinical findings were classified as (1) common conditions and anatomical variants, (2) reactive lesions, (3) benign tumour lesions and (4) premalignant lesions. The main locations of the oral mucosal findings were recorded on a topographical classification chart. Using correlational statistics, the findings were further associated with the known risk factors such as tobacco use and alcohol consumption. RESULTS: A total of 468 findings were diagnosed in 327 (53.17%) of the 615 subjects. In total, 445 findings (95.09%) were classified as common conditions, anatomical variants and reactive soft-tissue lesions. In the group of reactive soft-tissue lesions, there was a significantly higher percentage of smokers (P < 0.001) and subjects with a combination of smoking and alcohol consumption (P < 0.001). Eight lesions were clinically diagnosed as oral leukoplakias associated with smokeless tobacco. The prevalence of precursor lesions in the population examined was over 1%. CONCLUSIONS: Among young male adults in Switzerland, a significant number of oral mucosal lesions can be identified, which strongly correlate with tobacco use. To improve primary and secondary prevention, young adults should therefore be informed more extensively about the negative effects of tobacco use on oral health.

Maintaining an adequate tissue oxygen delivery (DO(2)) and consumption (VO(2)) is crucial in the treatment of septic patients. A fall in V0(2) is associated with a higher mortality. The early recognition of shock or tissue hypo perfusion impacts on patient prognosis. In occasions, hypovolemia or important regional oxygen debts are not recognized, since macro homodynamic variables have been compensated. In this situation, the use of metabolic hypo perfusion markers such as lactate, central venous oxygen saturation and gastric goniometry, can be helpful. However, interpretation of these markers should be cautious and always considering the overall clinical status of the patient. In the initial stages of sepsis, the dependency of V0(2) on DO(2) predominates as histopathological mechanism of multiple organic failure. In late stages, other factors predominate as determinants of multiple organic failure and mortality, such as hyper or hypo immune response, microcirculatory alterations and cytopathic hypoxia.

In abstinence maintenance programs, for reissuing the driving licence and in workplace monitoring programs abstinence from ethanol and its proof are demanded. Various monitoring programs that mainly use ethyl glucuronide (EtG) as alcohol consumption marker have been established. To abstain from ethanol, but not from the taste of alcoholic beverages, in particular non-alcoholic beer has become more and more popular. In Germany, these "alcohol-free" beverages may still have an ethanol content of up to 0.5vol.% without the duty of declaration. Due to severe negative consequences resulting from positive EtG tests, a drinking experiment with 2.5L of non-alcoholic beer per person was performed to address the question of measurable concentrations of the direct metabolites EtG and EtS (ethyl sulphate) in urine and blood. Both alcohol consumption markers - determined by LC-MS/MS - were found in high concentrations: maximum concentrations in urine found in three volunteers were EtG 0.30-0.87mg/L and EtS 0.04-0.07mg/L, i.e., above the often applied cut-off value for the proof of abstinence of 0.1mg EtG/L. In the urine samples of one further volunteer, EtG and EtS concentrations cumulated over-night and reached up to 14.1mg/L EtG and 16.1mg/L EtS in the next morning's urine. Ethanol concentrations in blood and urine samples were negative (determined by HS-GC-FID and by an ADH-based method).

Background This study compared frequency of alcohol consumption and binge drinking between young adult childhood cancer survivors and the general population in Switzerland, and assessed its socio-demographic and clinical determinants. Procedure Childhood cancer survivors aged <16 years when diagnosed 1976–2003, who had survived >5 years and were currently aged 20–40 years received a postal questionnaire. Reported frequency of alcohol use and of binge drinking were compared to the Swiss Health Survey, a representative general population survey. Determinants of frequent alcohol consumption and binge drinking were assessed in a multivariable logistic regression. Results Of 1,697 eligible survivors, 1,447 could be contacted and 1,049 (73%) responded. Survivors reported more often than controls to consume alcohol frequently (OR = 1.7; 95%CI = 1.3–2.1) and to engage in binge drinking (OR = 2.9; 95%CI = 2.3–3.8). Peak frequency of binge drinking in males occurred at age 24–26 years in survivors, compared to age 18–20 in the general population. Socio-demographic factors (male gender, high educational attainment, French and Italian speaking, and migration background from Northern European countries) were most strongly associated with alcohol consumption patterns among both survivors and controls. Conclusions The high frequency of alcohol consumption found in this study is a matter of concern. Our data suggest that survivors should be better informed on the health effects of alcohol consumption during routine follow-up, and that such counseling should be included in clinical guidelines. Future research should study motives of alcohol consumption among survivors to allow development of targeted health interventions for this vulnerable group.

Background: Alcohol is heavily consumed in sub-Saharan Africa and affects HIV transmission and treatment and is difficult to measure. Our goal was to examine the test characteristics of a direct metabolite of alcohol consumption, phosphatidylethanol (PEth). Methods: Persons infected with HIV were recruited from a large HIV clinic in southwestern Uganda. We conducted surveys and breath alcohol concentration (BRAC) testing at 21 daily home or drinking establishment visits, and blood was collected on day 21 (n = 77). PEth in whole blood was compared with prior 7-, 14-, and 21-day alcohol consumption. Results: (i) The receiver operator characteristic area under the curve (ROC-AUC) was highest for PEth versus any consumption over the prior 21 days (0.92; 95% confidence interval [CI]: 0.86 to 0.97). The sensitivity for any detectable PEth was 88.0% (95% CI: 76.0 to 95.6) and the specificity was 88.5% (95% CI: 69.8 to 97.6). (ii) The ROC-AUC of PEth versus any 21-day alcohol consumption did not vary with age, body mass index, CD4 cell count, hepatitis B virus infection, and antiretroviral therapy status, but was higher for men compared with women (p = 0.03). (iii) PEth measurements were correlated with several measures of alcohol consumption, including number of drinking days in the prior 21 days (Spearman r = 0.74, p < 0.001) and BRAC (r = 0.75, p < 0.001). Conclusions: The data add support to the body of evidence for PEth as a useful marker of alcohol consumption with high ROC-AUC, sensitivity, and specificity. Future studies should further address the period and level of alcohol consumption for which PEth is detectable.

To clarify the circumstances of death, the degree of inebriation is of importance in many cases, but for several reasons the determination of the ethanol concentration in post-mortem samples can be challenging and the synopsis of ethanol and the direct consumption markers ethyl glucuronide (EtG) and ethyl sulphate (EtS) has proved to be useful. The use of a rather stable matrix like vitreous humor offers further advantages. The aim of this study was to determine the concentrations of ethanol and the biomarkers in the robust matrix of vitreous humor and to compare them with the respective levels in peripheral venous blood and urine. Samples of urine, blood from the femoral vein and vitreous humor were taken from 26 deceased with suspected ethanol consumption prior to death and analyzed for ethanol, EtS and EtG. In the urine samples creatinine was also determined. The personal data, the circumstances of death, the post-mortem interval and the information about ethanol consumption prior to death were recorded. EtG and EtS analysis in urine was performed by LC-ESI-MS/MS, creatinine concentration was determined using the Jaffé reaction and ethanol was detected by HS-GC-FID and by an ADH-based method. In general, the highest concentrations of the analytes were found in urine and showed statistical significance. The mean concentrations of EtG were 62.8mg/L (EtG100 206.5mg/L) in urine, 4.3mg/L in blood and 2.1mg/L in vitreous humor. EtS was found in the following mean concentrations: 54.6mg/L in urine (EtS100 123.1mg/L), 1.8mg/L in blood and 0.9mg/L in vitreous humor. Ethanol was detected in more vitreous humor samples (mean concentration 2.0g/kg) than in blood and urine (mean concentration 1.6g/kg and 2.1g/kg respectively). There was no correlation between the ethanol and the marker concentrations and no statistical conclusions could be drawn between the markers and matrices.
