Prevalence of personality disorders in patients with eating disorders: a pilot study using the IPDE

EUROPEAN EATING DISORDERS REVIEW, Issue 4 2004
Izaskun Marañon
Abstract Objective The present study aims to determine the comorbidity of personality disorders (PD) with anorexia and bulimia nervosa, and to establish the major personality characteristics of eating disorders subtypes. Method Using the International Personality Disorders Examination (IPDE), the study investigated the personality profiles of 66 outpatients with eating disorders. Statistical analyses were carried out using non-parametric methods such as the Kruskal-Wallis H test and Mann-Whitney U. Results 51.5% of the overall sample met criteria for at least one personality disorder. Purging anorexia nervosa patients were the most affected. The most common personality disorders were obsessive-compulsive, avoidant, dependent, borderline and not otherwise specified. Discussion More than half of the subjects with AN and BN met the criteria for at least one PD. This finding is a challenge for clinical practice. Implications for further research in this area are commented on. Copyright © 2004 John Wiley & Sons, Ltd and Eating Disorders Association. [source]

Acute toxicity of para -nonylphenol to saltwater animals,

ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 3 2000
Suzanne M. Lussier
Abstract para -Nonylphenol (PNP), a mixture of alkylphenols used in producing nonionic surfactants, is distributed widely in surface waters and aquatic sediments, where it can affect saltwater species. This article describes a database for acute toxicity of PNP derived for calculating a national saltwater quality criterion. Using a flow-through exposure system with measured concentrations, we tested early life stages of four species of saltwater invertebrates and two species of fish. Static 96-h tests were also conducted on zoeal Homarus americanus, embryo-larval Mulinia lateralis, and larval Pleuronectes americanus. The number of organisms surviving the flow-through test was measured at 2, 4, 8, and 12 h and daily through day 7. Mortality for most species plateaued by 96 h. The ranked sensitivities (96-h 50% lethal concentrations, measured in micrograms per liter) for the species tested were 17 for Pleuronectes americanus, 37.9 (48-h 50% effective concentration) for Mulinia lateralis, 59.4 for Paleomonetes vulgaris, 60.6 for Americamysis bahia (formerly Mysidopsis bahia), 61.6 for Leptocheirus plumulosos, 70 for Menidia beryllina, 71 for Homarus americanus, 142 for Cyprinodon variegatus, and > 195 for Dyspanopius sayii. Values for the seven most sensitive of these species ranged over a factor of only 4.2. The narrow range of responses for PNP implies that exceeding a threshold concentration would endanger a large proportion of the aquatic community. [source]


Screening for gestational diabetes; past, present and future

DIABETIC MEDICINE, Issue 5 2002
F. W. F. Hanna
Abstract Gestational diabetes is carbohydrate intolerance, with onset or first recognition of hyperglycaemia during pregnancy. Several studies have suggested that gestational hyperglycaemia is associated with adverse maternal and fetal outcomes, promoting the case for screening. Conversely, others argue that screening for gestational diabetes may colour the clinical judgement, influencing further management, e.g. more ,unjustified' caesarean sections. Additionally, the lack of definitive data either on a clear-cut glycaemic threshold for the development of adverse outcomes or on the impact of intervention is emphasized by opponents of screening. This review attempts to evaluate the available data on screening for gestational diabetes. Oral glucose tolerance test is promoted on the basis that the diabetogenic stress of pregnancy is encountered during late gestation and is best recognized in the fed state. There are different tests, including the 1 h/50-g, 2 h/75-g and 3 h/100-g tests, with practical limitations, including the time and cost involved and the unpleasant supra-physiological glucose load that is unrelated to body weight, and issues of reproducibility and sensitivity/specificity profiles. Despite its convenience, the poor sensitivity of random glucose has precluded its routine use for screening. Fasting glucose appears to be promising but further testing is required to ensure satisfactory sensitivity/specificity in different populations. Despite its limitations, the oral glucose tolerance test has become established as the ,most acceptable' diagnostic test for gestational diabetes. More convenient methods, e.g. fasting or random or post-load glucose, have to be validated therefore against the oral glucose tolerance test to gain acceptance for routine screening. Diabet.
