Heroin abuse among Danish prisoners on remand. II. Consequences related to form of administration

Heroin-abusing Danish prisoners remanded in custody were based on interviews grouped as either smoking dependent (n = 18) or intravenous dependent (n = 55). Intravenous users had a longer duration and earlier debut of abuse than users who smoked opiates. Only intravenous users had serious somatic complications. Both groups of opioid dependent prisoners were marked by severe psychosocial dysfunction and considerable psychiatric co-morbidity. The intravenous users were generally more affected than the smokers concerning social and psychiatric parameters and earlier criminality, perhaps due to their longer duration of abuse.     

Prediction of reading and related academic problems.

Conducted a 5-yr longitudinal study to (a) compare psychometric vs behavioral kindergarten predictors of reading performance and (b) examine the effect on reading performance of particular classroom and school environments. Two cohorts of approximately 850 middle-class kindergarten children were administered a psychometric battery (e.g., the Wechsler Preschool and Primary Scale of Intelligence and the Bender Visual Motor Gestalt Test). Also, a Student Rating Scale consisting of 41 classroom behavior items representing 5 factors was completed for each S by the kindergarten teacher. The scale proved equal to the best psychometric measures in predicting reading test scores in the 1st, 2nd, and 3rd grades. Inclusion of classroom and school variables enhanced the prediction. Particularly instructive were analyses of false positive and negative prediction patterns. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Poisoning and overdose

The differential diagnosis of all patients with altered mental status must include drug toxicity. In particular, intentional or unintentional overdosing and/or poisoning are common emergency department presenting complaints. A comprehensive approach to managing these patients must incorporate aggressive information gathering, a careful physical examination looking for toxic syndromes, and diagnostic testing. Proper decontamination is the key to effective management, as is the use of specific antidotes when indicated.

Non-fatal mirtazapine overdose

Focal nodular hyperplasia (FNH) is an hepatic pseudotumoral lesion which is usually detected accidentally in subjects of any age. Definitive diagnosis requires histologic study, prior to analysis with imaging techniques. Three casos of FHN are presented characterized with Doppler ultrasonography in whom high frequency and low resistance central pulse flow were observed in contrast with the findings obtained in other benign hepatic lesions.     

Heroin addicts in substitution programs

40 heroin addicts of whom 20 were undergoing maintenance therapy with hydrocodone (Dicodid) and another 20 with methadone have been questioned by standardized interview regarding their previous history and present situation. With data on the history we examined how well heroin addicts succeed in getting away from criminality and prostitution and look for employment while undergoing drug maintenance therapy. We were also interested to learn whether reaching the aim depended on the maintenance medication, i.e. if hydrocodone is as appropriate as methadone for maintenance therapy. The inquiry showed a significant reduction of criminality and prostitution. The rate of employment was quite stable. The therapeutic successes, measured by employment, prostitution and criminality did not differ with medication by hydrocodone or methadone. Although the more reliable patients received hydrocodone and the less reliable methadone, they did not differ either in past history or in therapeutic success. We conclude that hydrocodone can be recommended for maintenance therapy of relatively reliable heroin addicts.     

Likelihood analysis of disequilibrium mapping, and related problems

In this paper a theory is developed that provides the sampling distribution of alleles at a diallelic marker locus closely linked to a low-frequency allele that arose as a single mutant. The sampling distribution provides a basis for maximum-likelihood estimation of either the recombination rate, the mutation rate, or the age of the allele, provided that the two other parameters are known. This theory is applied to (1) the data of H?stbacka et al., to estimate the recombination rate between a locus associated with diastrophic dysplasia and a linked RFLP marker; (2) the data of Risch et al., to estimate the age of a presumptive allele causing idiopathic distortion dystonia in Ashkenazi jews; and (3) the data of Tishkoff et al., to estimate the date at which, at the CD4 locus, non-African lineages diverged from African lineages. We conclude that the extent of linkage disequilibrium can lead to relatively accurate estimates of recombination and mutation rates and that those estimates are not very sensitive to parameters, such as the population age, whose values are not known with certainty. In contrast, we also conclude that, in many cases, linkage disequilibrium may not lead to useful estimates of allele age, because of the relatively large degree of uncertainly in those estimates.     

Anthropological aspects of alcohol consumption and alcohol related problems

Authors believe that drinking alcoholic beverages can be associated with customs and habits specific to small communities, societies and even entire nations. The primary family, as the foundation of customs and habits of the first generation, has a role in stimulating drinking and alcoholism. The authors have examined some sociocultural factors, mostly taking into consideration relations in the primary family, by means of a questionnaire filled out by alcoholics (N = 200) and non-alcoholics (N = 100). The alcoholics usually have their first drink earlier, start drinking regularly earlier, and in the primary family there is a high tolerance towards the use of alcoholic beverages. The authors believe that the prevention should be directed primary towards the primary family with a view to changing their customs and habits as well as attitudes towards the use of alcoholic beverages.     

The cost of antidepressant overdose

Ninety percent of suicide attempts referred to a general hospital are by self-poisoning. Among women, drug overdose is the commonest means of suicide. In a retrospective naturalistic review of 200 patients who were treated in the Critical Care Unit of a general hospital following medication overdose, 12% were antidepressant overdoses. The mean duration of hospital stay for overdose with tricyclic antidepressants (TCA) was more than double that for overdose with selective serotonin reuptake inhibitors (SSRI) (7 vs 3 days; z = 2.20, p < 0.05). The dollar cost of hospital treatment for patients who overdosed on TCAs was four times greater than that for patients who overdosed on SSRIs ($22,923 vs $5,379; z = 2.30, p < 0.05). The tricyclic compounds clearly have a price advantage over more recently introduced antidepressant agents fluoxetine, sertraline, paroxetine, venlafaxine, and bupropion. The apparent cost advantage of prescribing a less expensive drug may be nullified by the cost associated with adverse consequences.
