European union system for the evaluation of substances: the second version.

This publication presents major changes in the assessment of the risks of chemicals to human health and the environment as implemented in the second version of the European Union System for the Evaluation of Substances, EUSES 2.0. EUSES is a harmonised quantitative risk assessment tool for chemicals. It is the PC-implementation of the technical guidelines developed within the framework of EU chemical legislation for industrial chemicals and biocides. As such, it is designed to support decision making by risk managers in government and industry and to assist scientific institutions in the risk assessment for these substances. The development of EUSES 2.0 is a co-ordinated project of the European Chemicals Bureau, EU Member States and the European chemical industry. Several model concepts, the technical background and the user interface of EUSES have been improved considerably. Major changes in the environmental assessment such as the implementation of emission scenario documents for industrial chemicals and biocides, the addition of the marine risk assessment, the enhancement of the regional model to include global scales, and improvements in the secondary poisoning and environmental effects modelling will be discussed. The update of the human risk assessment module in EUSES focuses on the risk characterisation for both threshold and non-threshold substances with, among others, the introduction of assessment factors. The performance of EUSES is illustrated in an example showing the human and environmental risk assessment of a sanitation disinfectant for private use.

Rapid (partial) prescreening of cervical smears: the quality control method of choice?

Rapid rescreening of all negative and inadequate smears is the quality control method of choice in the UK. The sensitivity of primary screening of laboratory and individual screeners are major indicators of screening quality and are dependent on the number of false negative smears found by rapid screening for their calculation. High sensitivity may indicate good quality primary screening or poor quality rapid review. Quantifiably high quality rapid rescreening is essential if these sensitivity figures are to be meaningful. A 12-month study was undertaken in routine practice using the prescreening mode to ascertain the sensitivity of rapid (partial) screening in our department. The final results of smears were compared with those of rapid prescreening. The calculated sensitivity ranged from 92-54% for high-grade abnormalities and 75-33% for all grades, revealing a wide range of performance between individual prescreeners. Rapid prescreening can identify individuals best suited to rapid screening in routine practice. By using these prescreeners only, the sensitivity of cervical screening could be raised. Rapid (partial) prescreening should be considered as the quality control method of choice.

Maternal behaviors associated with smothering: a preliminary descriptive study.

OBJECTIVES: To describe maternal behavior in 15 women identified as having smothered their children. DESIGN: A descriptive study of maternal behavior and interaction with her child, using videotapes of mother and child together. These were obtained by covert video surveillance in a hospital setting. Maternal behavior was rated using an assessment schedule designed to be used with video. RESULTS: The mothers showed a range of behaviors. Three groups emerged; one whose interaction with the child resembled normal maternal behavior, a second who interacted in a hostile way, and a third who showed a paucity of interaction. CONCLUSION: These preliminary data suggest that smothering may reflect more than one type of abnormal maternal relationship or attitude towards children. This may have implications for treatment and prognosis.

Substance misuse as a marker of vulnerability among male prisoners on remand.

BACKGROUND: More treatment for substance misuse should be provided within prisons. AIMS: To examine differences between prisoners on remand with substance misuse problems and other prisoners on remand. METHOD: Random selection and interview of unconvicted male prisoners (n = 750, a 9.4% sample), plus examination of the prison medical record. RESULTS: Of the sample of 750, 253 subjects (33.7%) reported either drug- or alcohol-related health problems or dependency. Compared with other prisoners on remand, they reported more childhood adversity, conduct disorder, self-harm, past psychiatric treatment and current mood disorder, and had fewer qualifications, were more likely to be unemployed and have more housing difficulties. CONCLUSIONS: One-third of unconvicted men in prison report substance-related problems, and these are a marker for vulnerability within a disadvantaged population. Health care providers should involve this group in treatment and rehabilitation, both inside prison and following release.

Beliefs about childhood immunisation among Lebanese Muslim immigrants in Australia.

The aim of the study was to describe and analyse care values, beliefs, and practices relating to immunisation by Lebanese Muslim immigrants in New South Wales (NSW), Australia. This ethnonursing study explored the importance of care related to immunisation, knowledge of informants relating to vaccines, diseases, side effects, and contraindications. Family responsibilities relating to immunisation care services as well as expectations and evaluations of care services provided were also examined. Data were collected via observation-participation-reflection, including in-depth interviews. The findings revealed significant care themes for Lebanese Muslim informants based on their cultural values, beliefs, and practices related to health and immunisation. Culturally congruent nursing care practices related to immunisation for Lebanese Muslims in NSW, Australia, were identified.

Substance misusers remanded to prison--a treatment opportunity?

AIMS: To describe self-reported levels of substance misuse before arrest among remanded prisoners (unconvicted prisoners awaiting trial), to assess their degree of dependency on opiates and stimulants and to record their experiences of treatment in prison. DESIGN: Random selection of subjects from prisons chosen to give a geographical spread across England and Wales; self-report at semi-structured interview, plus examination of the prison medical record. SETTING: Thirteen male prisons, three Young Offenders' Institutions and three womens' prisons. PARTICIPANTS: Nine hundred and ninety-five consenting, unconvicted prisoners, randomly selected from all locations within the prisons: 750 men (9.4% sample) and 245 women (82.2% of all remanded women). MEASUREMENTS: CAGE Questionnaire, Severity of Dependence Scales (SDS) for daily users of opiates and/or stimulants. FINDINGS: Before arrest, 145 (19.3%) men and 72 (29.4%) women had been dependent on street drugs; 91 (12.1%) men and 16 (6.5%) women were solely dependent on alcohol. Seventeen (2.3%) men and four (1.6%) women reported injecting drugs during this imprisonment. Mean SDS scores were 10.6 for opiate and 7.7 for stimulant users. 244 (25%) of all subjects described withdrawal symptoms on reception into custody; 157 (16%) reported being prescribed some symptomatic relief; 235 (24%) requested treatment at interview. CONCLUSIONS: By extrapolation, 1905 people--23% of all unconvicted prisoners--want treatment for substance misuse. This apparent shortfall in provision must be addressed; the rapidity with which remanded prisoners return to the community dictates that prison and community services should be closely linked.

Impairment in the medical and legal professions.

Male doctors and lawyers are among the job groups with high mortality from alcohol-related diseases, although the prevalence of substance misuse among these groups is not known. Both professions have occupational risk factors. This article describes aspects of the work environment which have facilitated substance misuse by doctors and lawyers, and describes the professional consequences of addiction. Data will be presented from two studies: a retrospective casenote survey of doctors treated for substance misuse; and a questionnaire survey of lawyers in recovery from alcohol problems. Mechanisms for assisting impaired professionals into treatment have been developed in the UK and the USA. The most successful models separate health procedures from disciplinary procedures as much as possible, and offer a confidential evaluation and treatment program. Self-help groups play a crucial role in these therapeutic processes.

Point prevalence of mental disorder in unconvicted male prisoners in England and Wales.

OBJECTIVES: To determine prevalence of mental disorder among male unconvicted prisoners and to assess the treatment needs of this population. DESIGN: Semi-structured interview and case note review of randomly selected cross section of male remand population. Non-attenders were replaced by the next name on prison roll. SETTING: Three young offenders' institutions and 13 adult men's prisons. SUBJECTS: 750 prisoners, representing 9.4% cross sectional sample of male unconvicted population. MAIN OUTCOME MEASURES: Prevalence of ICD-10 diagnoses of mental disorder, and associated treatment needs. RESULTS: Psychiatric disorder was diagnosed in 469 (63%) inmates. The main diagnoses were: substance misuse, 285 (38%); neurotic illness, 192 (26%); personality disorder, 84 (11%); psychosis, 36 (5%); other and uncertain, 36 (0.5%). Subjects could have more than one diagnosis. The average refusal rate was 18%. In total 414 inmates (55%) were judged to have an immediate treatment need: transfer to an NHS bed, 64 (9%); treatment by prison health care services, 131 (17%); motivational interviewing for substance misuse, 115 (15%); and therapeutic community placement, 104 (14%). CONCLUSIONS: Mental disorder was common among male unconvicted prisoners. Psychosis was present at four or five times the level found in the general population. Extrapolation of our results suggests that remand population as a whole probably contains about 680 men who need transfer to hospital for psychiatric treatment, including about 380 prisoners with serious mental illness.

Doctors and substance misuse: types of doctors, types of problems.

The casenotes of 144 doctors who had received treatment for substance misuse were analysed. There were no differences between general practitioners (n = 61) and hospital doctors (n = 58) in terms of their substance misuse histories or the problems they incurred. Differences emerged between the consultant (n = 24) and the non-consultant (n = 34) grades of hospital doctor. The consultants were older at onset of problematic use (42.6 +/- 8.6 vs. 29.9 +/- 9.8 years); they suffered fewer career problems and misused fewer substances. The most frequent pathways into substance use were personality difficulties (76 subjects, 52.8%) and anxiety or depression (46 subjects, 31.9%). A history of depression (n = 36) was associated with perceived stress at work (p = 0.014), and at home (p = 0.06). Past neurotic disturbances (n = 20) were associated with personality difficulties (p = 0.035), anxiety or depression (p = 0.004), and with an earlier onset of problematic substance use (30.2 +/- 8.3 vs. 36.5 +/- 9.8 years, p = 0.014). Principal components of possible antecedents yielded one major component on which all elements loaded; this was labelled the 'disturbance score'. This score showed a reduction with increasing age of onset of problematic substance use.

Weighing up the pros and cons: help-seeking by drug misusers in Baltimore, USA.

Forty drug misusers receiving treatment in Baltimore completed questionnaires, originally administered to drug misusers in London, about their reasons for seeking help and their worries about the treatment. Seeking help was related to the experiences of addiction, loss of control over life and financial and family difficulties. The main fears were of failing treatment. These responses are similar to those obtained in the London group. There was little correlation between objective assessment and subjects' views of their problems. This study illustrates the complexities of coming for treatment and it emphasises the need for social and medical help.

Heat of fusion measurement of a low melting polymorph of carbamazepine that undergoes multiple-phase changes during differential scanning calorimetry analysis.

Two polymorphs of carbamazepine that melt at 176 and 189 degrees C and are known to be enantiotropic have been characterized more fully than in previous reports. For the first time, a value for the heat of fusion (29.3 kJ/mol) of the lower melting form is estimated, even though single melting DSC endotherms were not obtained. A method is described for summing the heat flows of intermediate transitions that occur when low melting carbamazepine is heated to a temperature where it will remain melted. The method should have general applicability in studies of polymorphs. Other characteristics of the carbamazepine enantiotropic pair are reported, including the transition temperature (71 degrees C).

Addiction as an occupational hazard: 144 doctors with drug and alcohol problems.

Information was abstracted from the hospital notes of 144 doctors who had received treatment for drug and alcohol dependency. These problems affect those in every specialty, and at all degrees of seniority. Over half came into treatment following medical referral. Social morbidity was an important contributory reason for seeking help. The mean age at presentation was 43.1 years; the mean duration of problematic use prior to this was 6.4 years for drug misusers and 6.7 years for alcohol misusers. Alcohol was the current problem for 41.6% and drug misuse for 26.4%; 31.3% were misusing both alcohol and drugs at presentation. Of the 83 subjects who were misusing drugs, only four had ever used blackmarket supplies. Psychotropic agents are readily available to doctors, but the consequences of this are not addressed. Those who develop dependency suffer a delay of years before reaching help.
