    Notes: Background:  Information on alcohol-associated oral mucosal lesions (OMLs) and conditions is meagre. A prevalence survey among alcohol misusers in south London was therefore undertaken.Methods:  Six hundred and ninety-three subjects (388 alcohol misusers and 305 alcohol + substance abuse) attending several clinical care facilities in south London between 1994 and 1999 were interviewed on their alcohol and drug habits. A comprehensive oral mucosal examination was performed, and soft tissue lesions found were classified by the clinical criteria of Axéll.Results:  Mean age of the sample was 40.5 years. The majority was white (92.6%); of the whites, 29.9% were Celts (i.e. Irish, Scots resident in London). Many subjects reported misusing more than one type of beverage. Two hundred and twenty-seven OMLs were found in 195 subjects (28.1%). The highest prevalences were found for frictional keratosis (8.8%), scar tissue of the lips (4.8%) and candidiasis (3.8%). Angular cheilitis was present in 21 subjects (3.0%). The alcohol-related OMLs detected were three white patches compatible with a diagnosis of leukoplakia and one treated oral carcinoma. No erythroplakias were detected. The differences in prevalence of mucosal lesions in the two groups were not significant (χ2 = 2.18; P = 0.14). The prevalence of tobacco smoking was high in both study groups. OMLs were found with all four types of beverages consumed, and there was little variation by the units per week consumed. Concurrent use of substances and alcohol did not make a significant difference to the prevalence of OML. In the logistic regression analysis, minority ethnic groups (Black or Asian), smokers, those with a body mass index (BMI) under 20 and beer drinkers had an increased risk of an OML in this group of alcohol misusers.Conclusions:  In comparison with previous oral mucosal screening programmes undertaken in several settings in the UK, the present study has yielded a higher prevalence of oral mucosal diseases and conditions in this risk population. There are several ways in which alcohol could contribute to these detected oral lesions, either directly or indirectly.

    Description / Table of Contents: Résumé L'action de Bacillus thuringiensis Berliner (Thuricide® HPSC WP) contre les chenilles d'Heliothis punctiger Wallengren a été contrôlée sur des graines de luzerne lors d'un essai en plein champ aven un carré latin 4×4. Les doses appliquées correspondaient à 1120, 560 et 112 g/ha. Tandis que les effectifs de chenilles ont augmenté dans les carrés témoins au cours des 4 jours après l'intervention, un grand nombre d'entre elles a été tué sur les 3 types de carrés traités. Les effects des 2 doses les plus élevées ont été semblables; la mortalité sur ces carrés ayant été respectivement de 69 et 71% le 4ème jour. Les grosses chenilles semblent avoir été touchées au même titre que les stades plus jeunes. Un modèle permettant de prévoir la mortalité de l'insecte cible a été appliqué aux données de l'essai en champ. En utilisant les données statistiques sur le taux de consommation des chenilles, la quantité de spores de B. thuringiensis initialement déposée sur le feuillage et le taux d'inactivation des spores exposées aux conditions écologiques, on a pu obtenir une estimation de la dose moyenne de spores ingérée par rapport à la dose médiane de traitement. A partir de cette dose, il a été possible d'évaluer la mortalité espérée des chenilles de 3éme stade dans le champ. La valeur obtenue était 66%, tandis que la mortalité obtenue au bout de 3 jours dans le champ était 71%. La discussion porte sur les conséquences de l'obtention d'une mortalité dans la nature prédictible dans un programme de lutte intégrée.
    Notes: Abstract The effect of Bacillus thuringiensis Berliner (Thuricide® HPSC WP) was tested against larvae of Heliothis punctiger Wallengren on seed lucerne in a 4×4 latin square field trial. Application rates corresponded to 1120, 560 and 112 g/ha. While larval numbers in the control plots increased for 4 days after application, numbers were suppressed in the three treatments. The effect of the two higher rates was similar-mortality in those plots was 69% and 71% respectively on Day 4. Large larvae appeared to be suppressed to the same extent as younger instars. A model for the prediction of target insect mortality was applied to data from the field trail. Using the statistics of feeding rate of larvae, the initial deposit of B. thuringiensis spores on foliage and the rate of inactivation of spores when exposed to environmental conditions, an estimate of average dose of spores ingested at the median application rate was obtained. From this dose the expected mortality in the field for third instar larvae was estimated. This value was 66%, while mortality obtained in the field after 3 days was 71%. The implications of the attainment of predictable field mortality as part of an integrated control programme are discussed.

    Notes: Abstract Plasma ionized calcium [Ca++] concentrations are decreased in patients having lactic acidosis. To further investigate this observation, we prospectively studied nine critically ill patients who had lactic acidosis and measured arterial pH, PCO2, [Ca++], lactate, and albumin concentrations. We found a strong association between decreased [Ca++] and increased plasma lactate concentrations (r 2=0.78,p≤0.001). This unexpected association — [Ca++] usually increases with increasing acidosis — might be clinically important and the mechanism deserves further investigation.

    Notes: Abstract In a patient with viral pneumonia, acute respiratory and renal failure and metabolic acidosis, a reduction in left ventricular stroke work was observed on the three occasions that 100 ml of 8.4% sodium bicarbonate was infused. Blood pressure and cardiac output decreased on two of the occassions. Since intravenous sodium bicarbonate may produce adverse cardiovascular effects, a right heart catheter should be inserted to monitor these effects when alkali therapy is administered to an acutely ill patient with metabolic acidosis.
