PERCEPTIONS OF DRINKERS AND ABSTAINERS IN A SAMPLE OF SCOTTISH ADULTS

Following Davies and Stacey's investigation (1972, Teenagersand Alcohol, HMSO, London) into perceptions of drinking andabstaining among Scottish teenagers, this study extended theirgeneral method to an investigation of the perceptions of 239Scottish adults. Results showed that the stereotypes of theheavy drinker as ‘tough and rebellious’ and theabstainer as ‘weak and cissy’ persist into adulthood.Heavy drinkers were seen as low on ‘sociability’and ‘sexual attractiveness’ and abstainers wereseen as less ‘sociable’ than moderate drinkers.There was also some evidence of a ‘double standard’in perceptions of male and female drinking roles. Other findingsconcerning the effects on perceptions of subjects sex and drinkingbehaviour are compared to those reported in the earlier studyand implications for the treatment of alcohol problems are discussed.It is concluded that the dimensions described by Davies andStacey represent a relatively stable structure within futureresearch where fresh initiatives in alcohol education may belocated.     

Continuous extradural infusion of lignocaine 0.75% vs bupivacaine 0.125% in primiparae: quality of analgesia and influence on labour

We studied 86 primiparous women with uncomplicated pregnancy and labour requesting extradural analgesia in labour. All the women were over 36 weeks of gestation with a cephalic-presenting singleton fetus. The women were allocated randomly to two groups: group A, who received an extradural infusion of lignocaine 0.75%, after an initial dose of 10 ml of lignocaine 1.5%, and group B, who received an infusion of bupivacaine 0.125% after an initial dose of 10 ml of bupivacaine 0.25%. All the women had their labour actively managed. Assessment of analgesia during labour and delivery, and the requirements for additional top-ups were noted, as were mode of delivery, requirement for oxytocic augmentation and incidence of fetal distress. Maternal and umbilical cord plasma concentrations of lignocaine were measured at delivery in 12 women receiving extradural lignocaine. There were no statistically significant differences between the two groups in terms of the mode of delivery, incidence of fetal distress, fetal heart rate abnormalities, or Apgar scores of the babies. Women in the bupivacaine group had a significantly better quality of analgesia during both the first and second stages of labour (p = 0.0005) and required fewer top-ups than those in the lignocaine group. However, the requirement for oxytocin augmentation during the first and second stages of labour was significantly less in the lignocaine group (p = 0.004). Similarly, the duration of the second stage was shorter compared with the bupivacaine group. In spite of high plasma concentrations of lignocaine, no side effects were noted in either mothers or babies.     

FLUMAZENIL IN ALCOHOL WITHDRAWAL: A DOUBLE-BLIND PLACEBO-CONTROLLED STUDY

The purpose of the present study was to study -aminobutyricacid (GABA)-A receptor function in alcohol-dependent subjectsduring withdrawal, using the benzodiazepine antagonist flumazenil.In particular, we wanted to examine the hypotheses that an endogenousinverse agonist ligand at the GABA-A benzodiazepine receptor(GBzR) is active during withdrawal (in which case flumazenilshould be anxiolytic), or whether chronic alcohol intake resultsin a shift in sensitivity of the receptor in the inverse agonistdirection (in which case flumazenil should be anxiogenic). Resultsfrom 15 alcohol-dependent subjects in a double-blind placebo-controlledcross-over study showed that flumazenil was neither anxiolyticnor anxiogenic, although withdrawal scores were reduced duringthe course of the study. The fact that flumazenil was not anxiogenic,as it is in panic disorder, suggests that the GBzR is functioningdifferently in these two clinically similar conditions.     

HIV risk-taking behaviour among injecting drug users currently, previously and never enrolled in methadone treatment

This study compares the injecting and sexual risk-taking behaviour among injecting drug users (IDUs) currently, previously and never enrolled in methadone maintenance treatment (MMT). All subjects had injected during the 6 months prior to the day of interview. The current MMT group showed significantly lower injecting risk-taking behaviour subscale scores on the HIV Risk-taking Behaviour Scale (HRBS) of the Opiate Treatment Index than the previous MMT and non-MMT groups together. The current MMT group differed from the other two groups in the frequency of injecting and cleaning of injection equipment with bleach. There was no difference between the current MMT group and the other two groups combined in sexual risk-taking behaviour scores on the HRBS. There were no differences between the previous MMT and non-MMT groups in injecting and sexual risk-taking behaviour. HIV seroprevalence was low and there was no difference in seroprevalence between groups. Thus, IDUs currently enrolled in MMT are at reduced risk for HIV infection when compared with IDUs who have previously or never been enrolled in MMT. However, the absence of a difference between the current MMT and other two groups in frequency of sharing behaviours suggests the need for additional strategies among MMT clients to reduce needle-sharing. Possible strategies include the application of relapse prevention interventions and the availability of sterile injecting equipment in MMT clinics. Further research is needed to identify factors which increase attraction and retention of IDUs to MMT.     

Language mixing in bilingual speakers with Alzheimer's dementia: a conversation analysis approach

Bilingual speakers with Alzheimer s disease (AD) may use the wrong language for the setting interlocutor or produce what appears to be an inappropriate mixture of their two languages. The few published studies to date examining this phenomenon have investigated it within a discourse analysis framework, interpreting the behaviour either as a problem of language choice (choosing the appropriate language in which to converse) or language separation (keeping two languages separate in production). These authors contend that while such a distinction is theoretically feasible, it is extremely problematic to apply these labels to actual conversational data. Using examples from free conversations of four bilingual women with AD, some of the difficulties inherent in a discourse analytic approach to this question are illustrated. Applying principles from conversation analysis (CA) it is argued that a methodology that is data driven and context relevant offers more valuable insights into individuals language use and interaction. It avoids the inconclusiveness of the choice-separation dichotomy and offersmore constructive accounts of whether and how language behaviour is appropriate or not.
