Sustainable treatment systems for removal of pharmaceutical residues and other priority persistent substances

Pharmaceutical residues and other emerging substances commonly summarised as micropollutants pass through wastewater treatment plants (WWTPs) and end up in the receiving waters and sludge. Many studies have investigated the removal efficiency of various techniques but a holistic evaluation of various relevant treatment alternatives regarding both the removal efficiency for various micropollutants, investment and operating costs, environmental impacts and future comprehensiveness is still lacking. This paper provides the results from a large 3-year project about the evaluation of sustainable treatment systems for removal of various micropollutants or disruptive effects at Swedish WWTPs and their environmental, economic and future sustainability. The presented results are based on our own pilot tests and related assessment and modelling efforts and provide a holistic view on advanced treatment of wastewater for removal of micropollutants.

Congenital Hypothalamic "Hamartoblastoma" Versus "Hamartoma": Suggestions for Neuropathologic Terminology Emanating From a Mid-gestational Autopsy Case of Pallister-Hall Syndrome

Pallister-Hall syndrome (PHS) is a rare malformative disorder that is due to truncating functional repressor mutations in GLI3. Since the seminal publication in 1980, hypothalamic tumors have been recognized to be a cardinal feature of PHS. In their original description of the neuropathologic features of PHS, Clarren et al. coined the term "hamartoblastoma" to characterize what they deemed to be a dual malformative and neoplastic mass of the hypothalamus. In subsequent published cases/series of PHS, the term "hamartoma" was often substituted for hamartoblastoma given what appeared to be a benign natural history of this lesion. Additional confusion in the literature has ensued since most hypothalamic hamartomas (HH) encountered on the clinical neuropathology service are "isolated" in nature (ie, no other congenital malformations) and present in a very different and stereotypical fashion with gelastic seizures and/or precocious puberty. While genomic investigations of isolated HH have begun to uncover a mutational profile of these cases, GLI3 mutations have only been recognized in a small subset of isolated HH. Herein, we describe the autopsy findings from a 21-week gestational age fetus with features of PHS. Moreover, we provide a detailed description of the hypothalamic tumor affecting this fetus and propose a novel subclassification of HH, distinguishing syndromic from isolated forms based upon the presence or absence of neocortical-like areas.

Birth outcomes of pregnancies fathered by men with multiple sclerosis

We linked several population-based clinical and health administrative databases in British Columbia, Canada. We identified and compared birth outcomes of pregnancies fathered by men with multiple sclerosis (MS) (n=202) and men from a frequency-matched general population cohort (n=981) between 1996 and 2010. Using multivariate models, we analyzed the association of paternal MS, disease duration at conception and disability (as measured by the Expanded Disability Status Scale) with birth weight and gestational age. Paternal MS and MS-related clinical factors were not significantly associated with birth outcomes (p>0.05). This study provides assurance to expecting fathers with MS and their families.

Labor induction and augmentation in women with multiple sclerosis

Background:

Fatigue and pelvic organ dysfunction are common among women with multiple sclerosis (MS), which may prolong labor and increase the risk of labor induction and/or augmentation.

Objective:

We set out to investigate the association between MS and related clinical factors (disease duration and the Expanded Disability Status Scale, EDSS) with labor induction/augmentation.

Methods:

Data from the British Columbia (BC) MS database were linked with the BC Perinatal Database Registry. Multivariable models were used to compare the likelihood of labor induction and augmentation between attempted vaginal deliveries (1998–2009) in women with MS ( n=381) and the general population ( n=2615).

Results:

In the MS cohort, 94/381 deliveries (25%) required labor induction and 147/381 deliveries (39%) required labor augmentation. Having MS was not associated with labor induction (adjusted odds ratio (OR)=0.91; 95% confidence interval (CI)=0.68–1.22, p=0.54) or augmentation (adjusted OR=0.91; 95% CI=0.72–1.15, p=0.43), but was associated with multiple methods of labor induction (OR=1.94; 95% CI=1.23–3.06, p=0.004). A higher EDSS score was associated with an increased risk of labor induction (adjusted p=0.04), but not labor augmentation (adjusted p > 0.5). Disease duration was not associated with either outcome (adjusted p > 0.2).

Conclusions:

Greater intervention may be required to initiate labor for women with a higher degree of disability due to MS.

Perinatal outcomes in women with multiple sclerosis exposed to disease-modifying drugs

Background: The incidence of disease-modifying drug (DMD) exposure during pregnancy in multiple sclerosis (MS) is unknown and limited data exists regarding the potential harm of DMD exposure during pregnancy.

Objective: To investigate the incidence and effect of in utero DMD exposure on perinatal outcomes.

Methods: We conducted a retrospective analysis by linking two provincial, population-based databases, the British Columbia (BC) MS database with the BC Perinatal Database Registry. Delivery (duration of the second stage of labor, assisted vaginal delivery and Cesarean section) and neonatal (birth weight, gestational age, 5-minute Apgar score and congenital anomalies) outcomes were compared between women exposed and unexposed to a DMD within 1 month prior to conception and/or during pregnancy. Findings were reported as odds ratios (ORs) with 95% confidence intervals (CIs).

Results: In all, 311 women with relapsing–remitting MS delivered 418 singleton babies between April 1998 and March 2009. 21/101 (21%) of births to MS women treated with DMD prior to pregnancy were exposed to a DMD. In all cases, exposure was documented as unintentional and DMD treatment was stopped within 2 months of gestation. The overall incidence of exposure was 21/418 (5%). DMD exposure was associated with a trend towards a greater risk of assisted vaginal delivery compared to the DMD naïve groups (OR = 3.0; 95% CI: 1.0–9.2). All other comparisons of perinatal outcomes were unremarkable.

Conclusion: The incidence of DMD exposure was relatively low and no cases were intentional. Further studies are needed to ascertain the safety of DMD exposure during pregnancy in MS.

Pathways to suicidal behaviour among adolescent girls in Nicaragua

Adolescent girls are the most frequent suicide attempters worldwide. However, there is little knowledge about pathways leading to suicidal behaviour among young people, in particular in low-income countries. This study explores the motives and processes related to suicidal behaviour among young girls in Nicaragua. Individual in-depth interviews were conducted with eight girls aged between 12 and 19 admitted to hospital after attempting suicide. The audio-taped interviews lasted 2-4 h and were transcribed, translated into English and coded for content. Grounded theory and content analysis were used to construct a theory of the mechanisms behind their suicidal behaviour. A tentative model exploring pathways to suicidal behaviour is described with four main categories: structuring conditions, triggering events, emotions and actions taken. The model illustrates the dialectic interplay between structure and actions taken. Actions taken were categorized as problem solving or various forms of escape where failure with either of these strategies resulted in a suicide attempt. Dysfunctional families, absent fathers and lack of integration into society were some of the structuring conditions that lead to emotional distress. Abuse, deaths in the family, break-up with boyfriends or suicide among friends acted as triggering events. A striking finding was the obvious narrative competence of the girls. Our findings indicate that suicide prevention programmes for young people must offer support from professionals, independent of their family and social networks. Institutions in the community in contact with young people with suicidal behaviour must develop communicative skills to offer a trusting environment mobilising the resources that young people have.

Experiences against HIV/AIDS/STDS of Somalis in exile in Gothenburg, Sweden

Since 1989, the City of Göteborg Immigrant Services Administration has been making efforts to inform about HIV/AIDS. The purpose has been to ensure that even immigrant residents of the City of Göteborg (Gothenburg) have access to relevant information about HIV/AIDS. The administration's efforts have been a part of the collected efforts of Gothenburg to prevent the spreading of HIV. This paper attempts to discover and describe experiences against HIV/AIDS/STDs of Somalis in Exile in Gothenburg, Sweden. A qualitative sociological in-depth interviews with 13 individuals (6 women and 7 men) and with semi-structured and themetized emerging design was carried on. A follow up focus group interviews with 10 individuals (2 women and 8 men) was also performed. The paper reveals that the general understanding of subjects on the issues under discussion is almost the same though details may vary from one research participant to the other. They have described this through narratives. STDs and specially HIV/AIDS was perceived as something dishonourable by the subjects. The HIV/AIDS is perceived as a sin which Allah sends to punish those who have fornication or sex without marriage (Zinna). Of course, this tendency of shying off the problem leads to ignorance of how to behave, which in turn decreases the risk of perceptions and as a result may also increase the risk of being infected. As concerns protection as a preventive measure, attitudes vary. The traditionalists have argued that condom increased the possibility of promiscuity or fonication, while young and more modern people saw condom as something good. We may conclude that Somalis who have arrived in Western world and in Sweden as adults did never have a modern sexual education for themselves due to socio-cultural reasons and this has important implication for giving proper information to their children about sex organs, human sexual development and preventive measures against HIV/AIDS/STDs. These immigrant parents should be offered culturally sensitive communication and educational programmes aimed at raising their awareness about teenagers sexuality and the preventive measures against HIV/AIDS/STDs.

Gendered experiences of conflict and co-operation in heterosexual relations of Somalis in exile in Gothenburg, Sweden

Political upheaval and poverty at home has been forcing many Somalis to immigrate. These immigrants do not only leave their physical house, families, relatives, loved ones, friends, but also familiarities, culture, customs, and often they do end up in no man's land being between their own and new home culture. Available reports suggest that there are about 15,000 Somalis in Sweden and their majority came here from late 1989 to 1996. About one third these immigrants live in and around the city of Gothenburg. This paper explores and describes gendered experiences of conflict and co-operation in heterosexual relations of Somalis in exile in Gothenburg, Sweden. A qualitative sociological in-depth interviews with 6 women and 7 men was performed during May 1999 to January 2000. A follow up focus group interviews with 10 people (2 women and 8 men) was also carried on. The results show that both the Somali culture and Muslim religion do not support the children being taught sex education in schools or the names of the sex organs being pronounced other than to be used as metaphors. The girls, unlike their age group males, experience a very painful and terrifying process during childhood in which their self-esteem is downgraded by means of serious degrading traditional active violence such as female genital mutilation and visible virginity control. The narratives tell stories in which Somali women are degraded and expected to obey in situations characterised by their man's arbitrariness. They are subject to a very extensive form of social control, which is especially pronounced on issues regarding sexuality. Their integrity as women is, consequently set aside. When Somali refugees came to Sweden some of them came to adopt much of the modern lifestyle and cultural norm systems, preferable young people and some of the females. Relating to a new culture with its new expectations on the norm obedience also created changes in self-esteem. Exile situation tends to generate horizontal conflicts, among spouses and between groups of people. It also tends to generate vertical conflicts because now generations stand up against each other and this is especially pronounced when it is about issues of sexuality and sexual relations. The young generations questions their parents authority. They are now living in new social context and perceive risks, as well as possibilities. Their new dreams and choices, however, do not fit their parents' expectations, which sometimes leads to big problems. From a traditional perspective these deviants lack of respect for traditions and the original culture. From a male perspective this means more specifically a lack of respect for male dominance and superiority.

A 2-year follow-up of 120 Swedish female alcoholics treated early in their drinking career: prediction of drinking outcome

BACKGROUND

One hundred twenty women alcoholics recruited to a treatment program called EWA (Early Treatment for Women With Alcohol Addiction) were studied. The selected women were not previously treated for alcohol abuse.

METHODS

The women were followed up by use of a structured personal interview, biomarkers sensitive for alcohol abuse (i.e., glutamyl transpeptidase), and questionnaires, by using defined criteria for abstinence, social drinking, satisfactory drinking outcome, and unsatisfactory drinking outcome.

RESULTS

Drinking outcome was good (i.e., total abstinence, social drinking, or satisfactory drinking outcome) for 67% of the women during the total follow-up time, by use of strict criteria for relapse. The results were corroborated by the biomarkers. Similar results were reported from two previously studied groups of women from the same department. However, the frequency of abstinence was higher and social drinking was significantly lower among this sample of women. Daily drinking, the use of sedatives, and a long duration of pretreatment alcohol abuse predicted an unfavorable outcome. However, a long duration of outpatient treatment predicted a good outcome, whereas treatment dropout was related to an unsatisfactory drinking outcome. A majority of the women (96%) rated the treatment experience and the treatment program favorably. The overall good results might reflect the selection of the subjects studied.

CONCLUSIONS

Improving treatment program adherence would probably improve outcome for the women with an unsatisfactory drinking outcome.

Prenatally diagnosed microcephaly: a review of etiologies

OBJECTIVE

To determine the incidence and etiology of prenatally diagnosed microcephaly.

METHODS

Retrospective review of 10 years at a tertiary obstetrical hospital. The study population consisted of 21 infants with confirmed prenatal and postnatal microcephaly.

RESULTS

There were 8 different definite/probable etiologies identified (viral, monochorionic twinning, genetic syndrome, neural tube defect, abnormal karyotype, hypoxic insult, constitutional).

CONCLUSIONS

Retrospective study indicates the commonest etiologies for prenatal microcephaly are in utero infection, monochorionic twin insult, rare genetic syndrome and chromosomal anomalies.

Oral health behaviour and self-esteem in Swedish children

This study focus on the socio-psychological concept of self-esteem and examines its association with oral health behaviour and with some background variables that have been shown to be of importance in previous studies. In 1995, 3370 12-year-olds answered a questionnaire on social and demographic factors. Questions on attitudes and behaviour were also included. After reducing the number of variables and constructing new variables, multivariate analyses were performed. A polytomous regression on self-esteem showed that having very poor self-esteem as opposed to poor, good and very good self-esteem was associated with being a girl, not living with one's biological parents, poor social support, having less interest in politics, poor adaptation in school and poor oral health behaviour. The results also showed that being a boy, choosing statements reflecting less exemplary behaviour, and being less well adapted in school increased the risk of having poor oral health behaviour, as did ethnic group affiliation and having poor self-esteem. Our results showed that self-esteem is a crucial intervening variable between variables measuring social background and outcome variables, especially oral health behaviour.

Somalis giving birth in Sweden: a challenge to culture and gender specific values and behaviours

OBJECTIVES

Giving birth in a foreign country implies going through a life event with little or no access to your own traditions and social support. The aim of this study was to study the childbirth experiences of Somali women and men in Sweden.

DESIGN

Qualitative. Nine women and seven men were interviewed. Data collection was characterised by an openness to new ideas during the interview and the interviews were analysed according to the grounded theory technique.

FINDINGS

The meeting of Somalis with Swedish antenatal and delivery care was a multicultural event. It revealed social, medical, cultural and gender factors advocating space in the arena of childbirth. The Somalis constituted a homogeneous group with regard to their cultural belonging and motives for exile. The subjects were heterogeneous in that they represented a great variety in social and demographic background as well as in experiences, feelings and modes of expression. One striking finding was the Somali man's dramatic entrance into childbirth, which seemed to have a strong impact on the Somali woman's well-being during delivery. The study showed difficulties in getting used to the Swedish model of parenthood and in finding new role divisions in the couple relationship. Some of the subjects had experienced a strengthening of their marriage and an increased understanding of each other. Others commented that various aspects of traditional womanhood and manhood were lost as a result of the unfamiliar gender structures in Sweden.

CONCLUSION

The Somalis' experiences of childbirth in Sweden can be understood by using the theoretical concept of gender, rather than culture. Our own and other studies show that women and men may have different frames of reference in childbirth, where the women mainly focus on biological circumstances and the men on the social and cultural aspects of birth. The Somali couple were found to be vulnerably positioned, with the professionals having the important role of supporting and empowering Somali parents.

Personality characteristics of women with alcohol addiction: a Rorschach study of women in an early treatment programme

This study identifies personality characteristics in a group of Swedish women (N = 60) attending their first treatment for alcohol problems. The treatment programme specifically addressed women in an early phase of their drinking career, and was called "Early Treatment of Women with Alcohol Addiction" (EWA). Rorschach personality profiles of the 60 women differed significantly in almost all investigated aspects in a psychopathological direction from norms reported by Exner for a reference group of female non-patients. The findings are consistent with the assumption that, although the EWA women were socially well-functioning and fairly early in their drinking career, they nevertheless reveal serious underlying psychopathology. Clinical implications of the findings are discussed.

Communicating with the people about HIV infection risk as a basis for planning interventions: lessons from the Kagera Region of Tanzania

In order to deepen the understanding of risk factors associated with HIV infection in the Kagera region of Tanzania and to investigate the potentials of communicating with the people in planning for interventions, two studies were performed in the districts of Bukoba Urban, Bukoba Rural and Muleba in 1989. The HIV prevalence of these areas ranged between 4.5% and 24.2% according to the prevalence study performed earlier in 1987. The studies involved the community in ward meetings on the one hand, and previously studied individuals on the other hand. The studies aimed both at conveying to the people the results of a previously performed study and at collecting new data using a combination of quantitative and qualitative methods in order to better understand the associated risk factors, perceived or real, and what suggestions the community could offer for reducing HIV transmission in the region. From the initial study, awareness about AIDS was found to be universal. Change of sexual partners and infection with syphilis were found to be the major risk factors for HIV-I infection. From the ward meetings people suggested a variety of solutions for interventions which we have categorized as either "hard" or "soft". The "hard" solutions involved suggestions such as isolation, imprisonment, castration and killing of AIDS victims, while the "soft" solutions involved sympathetic handling of the sick and educating the people about the modes of transmission and how best to prevent infection. There was a greater tendency for the low HIV prevalence rural communities to suggest the "hard" solutions than the high HIV prevalence urban ones which tended to suggest the "soft" solutions. However, with the changing dynamics of HIV infection in the region towards higher HIV prevalence in rural areas, it is likely that the "soft" solutions will gain acceptance and become adopted for interventions throughout the region. The information obtained from these studies has provided lessons that can be used for rational counselling as well as for guiding the implementation of IEC activities geared at interventions. It is also suggested that there should be further research into new strategies or their combinations which could be crucial in prevention such as those of community participation, empowerment of women and solidarity in AIDS intervention work.

Early treatment of women with alcohol addiction (EWA): a comprehensive evaluation and outcome study. I. Patterns of psychiatric comorbidity at intake

This paper deals with psychiatric comorbidity among 60 women problem drinkers treated in a specialized women-only treatment programme (EWA) at Karolinska Hospital, Stockholm, Sweden. The programme attracts women who have not been previously treated for alcohol problems. The methods used were structured interviews (SCID-I and SCID-II) applied at least 10 days after the start of treatment. All but two of the women had a definite alcohol dependence according to the DSM-III-R, and a majority (60%) also fulfilled the criteria for at least one psychiatric disorder during their lifetime. However, only 23% had a personality disorder (PD), and all subjects with a PD also had at least one Axis I disorder. The most common disorders were mood disorders (48%) and anxiety disorders (38%). However, alcohol dependence developed without definite pre-existing psychiatric disorders among a substantial proportion of the women (40%). It remains to be seen whether and how psychiatric disturbances among female problem drinkers affect treatment compliance and long-term outcome.

Co-operation, participation and conflicts faced in public health--lessons learned from a long-term prevention programme in Sweden

A comprehensive community-based programme for prevention of cardiovascular diseases (CVD) and diabetes was established in 1985 in a small municipality in northern Sweden. A cross-sectional survey to the general public was performed and semi-structured open-ended interviews were taken of actors at different levels. Notes from official records were also included in the study. The aim was to describe and discuss some factors that promote or constrain community participation in health programmes. The results generally confirmed that the right of definition concerning the health programme mainly remained with the health professionals. Community participation was mainly defined by the actors based on the medical and health planning approach and, thereby, as a means to transform health policy plans into reality by transmitting health knowledge and increasing consciousness among the citizens of the need for changing lifestyles. However, participation as a means of identifying problems and demonstrating power relationships and as elements in promoting local democracy was hardly represented among the actors at all. Overall, the CVD health programme was characterized by consensus between the actors. Despite this, debates and arguments about interpretations, social interests, personal conflicts and ideological constraints were observed. However, a majority of the public wanted the CVD preventive programme to continue.

Socio-geographical patterns of HIV-1 transmission in Kagera Region, Tanzania

A population-based study on the prevalence of HIV-1 infection in the Kagera region was performed in 1987. The study was based on a multistage cluster sampling technique covering the age-group 15-54 years. The study showed considerable variation of prevalence of HIV-1 infection in the areas studied. A total of 2475 adults were studied and the overall prevalence of HIV-1 infection in the region was 9.6% with a higher prevalence in the urban area (24.2%) compared to that in the rural areas (4.9%). In the present analysis, information on individuals collected during the prevalence study has been used to characterize smaller geographical areas of several villages (wards) and to form the basis for an aggregated analysis of geographical and social patterns relevant to HIV-1 transmission in the studied areas of the region. Kagera region is a heterogeneous society with respect to, for example, religion, ethnic groups and family patterns. There was a moderately strong positive correlation between HIV-1 prevalence and frequent change of sexual partners on the ward level. In Bukoba town the prevalence varied remarkably among the wards, with the lowest prevalence in the ward having the highest social status. In the rural areas, however, the prevalence in the wards decreased considerably with increasing distance from Bukoba town. This aggregated analysis of socio-geographical patterns of HIV-1 transmission characteristics has provided us with information for prioritizing areas of HIV/AIDS intervention in the Kagera community.

Behavioural effects of prenatal metallic mercury inhalation exposure in rats

The effects of administration by inhalation of metallic mercury vapour (Hg0) to pregnant rats, approximately corresponding to doses of 0.2 mg Hg0/kg/day (high dose) or 0.07 mg Hg0/kg/day (low dose), on the developmental and behavioural repertoire of the offspring were studied. Exposure occurred during days 11-14 plus 17-20 of gestation. The dose levels were selected so as not to induce maternal toxicity. Maturation variables such as surface righting, negative geotaxis, pinna unfolding, and tooth eruption revealed no differences between Hg0-treated offspring and controls. Tests of spontaneous motor activity showed that the Hg0-treated offspring were hypoactive at 3 months of age but hyperactive at 14 months. In spatial learning tasks the prenatally exposed offspring showed retarded acquisition in the radial arm maze but no differences in circular swim maze. A simple test of learning, habituation to a novel environment (activity chambers), indicated a reduced ability to adapt. These data suggest that prenatal exposure to Hg0 vapour results in similar behaviour changes in the offspring as reported for methylmercury.

AIDS epidemic in Kagera region, Tanzania--the experiences of local people

This study is part of a collaborative study of HIV infection and AIDS which was launched in 1987 in the Kagera region, Tanzania. This region is characterized as one of the areas most affected by the AIDS epidemic. In order to describe and analyse the epidemiology of HIV infection in the area and also to contribute to the intervention process, a long-term population-based project was initiated. The study was launched in January 1989 as an in-depth behavioural study to describe the experiences of the local people of the AIDS epidemic in the region. The specific objectives were to determine the people's attitudes, perceptions, responses and norms relevant to AIDS-related problems. The data were collected through tape recorded interviews, focus group discussions and direct observations of risk behaviour. The interviews were conducted in 10 villages, in urban and rural Bukoba as well as in Muleba districts. In each village five households were selected and visited once a week for about 6 months. The focus group discussions were held mainly with young males, females, married women and married men, elders and religious leaders, government and party leaders, and other key informants. Perceptions, attitudes and patterns of behaviour among the local people are described in the context of the HIV transmission in the area. The descriptions give answers to questions like: How do people perceive and interpret AIDS? How do they react to AIDS? How do they judge causes and risks? What are the attitudes to people with AIDS and those suspected to have AIDS? What are the implications of these values in affected communities?

Behavioural effects of neonatal metallic mercury exposure in rats

The effect of neonatal exposure of rats to mercury vapour (Hg0), at the concentration 0.05 mg/m3, 1 h (low dose) or 4 h (high dose), on the behaviour in adulthood were studied. Exposure occurred on days 11-17 (the period of rapid brain growth). Tests for spontaneous motor activity were performed at the ages of 2 and 4 months. Rats exposed to the high dose Hg0 showed a marked increase in variables locomotion and total activity but a decrease for rearing when tested at 2 months of age. At 4 months of age these rats showed a marked hypoactivity with respect to all three variables. Rats exposed to the low dose showed no significant differences at 2 months compared to controls. However, at the age of 4 months the same pattern (increase in variables locomotion and total activity but a decrease for rearing) already noticed in the high dose group at 2 months was observed. In the spatial learning tasks applied, the radial arm maze and circular swim maze, neonatally exposed pups showed a retarded acquisition to the former, while there was no difference compared to controls in the latter. These data indicate that neonatal exposure to mercury vapour results in similar behaviour changes as reported from offspring prenatally exposed to mercury vapour or methylmercury. Furthermore, exposure for 1 week to concentrations around Swedish threshold values (TLV) for 1 or 4 h resulted in dose and age-related behavioural changes.

Are special treatment facilities for female alcoholics needed? A controlled 2-year follow-up study from a specialized female unit (EWA) versus a mixed male/female treatment facility

Women with alcohol problems constitute an increasing number of patients in medical service. Do they need special care? How should the treatment program be designed? The specialized female Karolinska Project for Early Treatment of Women with Alcohol Addiction (EWA) unit at the Karolinska Hospital in Stockholm, Sweden, was opened in 1981. The aim of the project is to reach women in an early stage of alcohol dependence behavior and to develop treatment programs specific to the needs of females alone. In order to investigate the value of such a specialized female unit a controlled 2-year follow-up study was carried out including 200 women. The probands were treated in the female only EWA-unit, whereas the controls were placed in the care of traditional mixed-sex alcoholism treatment centers. The 2-year follow-up study showed a more successful rehabilitation regarding alcohol consumption and social adjustment for the women treated in the specialized female unit (EWA). Improvement was noted also for the controls but to a lesser extent. Probably one of the most important achievements of a specialized female unit, such as EWA, is to attract women to come for help earlier.

The effect of different vigabatrin treatment regimens on CSF biochemistry and seizure control in epileptic patients

1. Vigabatrin, 50 mg kg-1, was administered orally as add-on therapy to 11 patients with drug-resistant complex partial epilepsy as a single dose, then once every third day for 2 months, every other day for 2 months and daily for 1 month. 2. Lumbar punctures were carried out prior to treatment and at the end of each dosage regimen and cerebrospinal fluid (CSF) evaluated for concentrations of free and total GABA, homocarnosine (GABA-histidine dipeptide), homovanillic acid (HVA), 5-hydroxyindole acetic acid (5-HIAA) and vigabatrin. 3. Each regimen resulted in significant increases in CSF concentrations of free and total GABA and homocarnosine compared with the immediately preceding regimen. 4. CSF concentrations of HVA significantly increased after a single vigabatrin dose but returned to pre-treatment levels with subsequent dosing schedules. In contrast, 5-HIAA concentrations also increased with the single dose but were significantly decreased, compared with pre-treatment values, following alternate day and daily vigabatrin administration. 5. Seizure frequency progressively decreased with decreasing dosing interval. Daily vigabatrin administration was associated with greater than 50% decrease in seizures in 8 of the 10 patients treated.

Carbohydrate-deficient transferrin (CDT) in serum in women with early alcohol addiction

Carbohydrate-deficient transferrin (CDT) in serum was determined by micro anion exchange chromatography and a transferrin radioimmune assay in 58 consecutive women treated for early alcohol dependence compared, with 62 healthy females with an alcohol consumption of 0-15 g of ethanol/day. The upper normal CDT level was 74 mg/l. CDT was elevated above this value in 83% of the alcoholic women with an intake of 60 g of ethanol/day or more for at least 7 days within the preceding two weeks. CDT values were significantly positively correlated with daily alcohol consumption but not with GT, ASAT, ALAT or MCV. During abstinence CDT level declined exponentially with a half-life of 14 +/- 3 days. The results indicated that CDT may be as sensitive and specific a marker in women with early alcohol addiction as in previously studied male alcoholics. The amount of alcohol consumed appeared to be more important than sex or liver function. Determination of CDT may thus offer a means for early objective diagnosis and adequate treatment also of women in early stages of alcoholism.

Effects of single doses of vigabatrin on CSF concentrations of GABA, homocarnosine, homovanillic acid and 5-hydroxyindoleacetic acid in patients with complex partial epilepsy

Vigabatrin, as a single oral dose of 50 mg/kg, was administered to 11 patients with drug-refractory complex partial epilepsy. Serial lumbar punctures were performed prior to and 5 times within the first week following treatment. Cerebrospinal fluid (CSF) concentrations of total GABA, free GABA, homocarnosine, homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) and vigabatrin were determined as well as blood vigabatrin levels. CSF GABA, homocarnosine, HVA and 5-HIAA concentrations increased by 6 h after the single dose and remained elevated for up to 5-7 days. In contrast, CSF and blood vigabatrin levels were maximal within the first 24 h and were no longer detectable thereafter. Hence, these results are consistent with vigabatrin acting as an irreversible inhibitor of GABA-transaminase and suggest that it may also increase biogenic amine turnover.

Symptoms of tobacco withdrawal from total cigarette cessation versus partial cigarette reduction

The study examined the occurrence of acute tobacco withdrawal symptoms among three methods of smoking cessation. Smokers were asked to smoke ad lib for 3 days and then randomly assigned to one of three groups for the next 5 days: (1) total cigarette cessation; (2) 50% reduction of number of cigarettes; or (3) reduction of nicotine yield of cigarettes. Of the 13 measures of tobacco withdrawal, six of the measures showed significant differences in severity of withdrawal symptoms between the total cessation group and partial reduction groups. There were no significant differences in severity of withdrawal between the two partial reduction groups.

Peripheral markers in the female "hidden alcoholic"

Mean corpuscular volume, thrombocyte count and levels of gamma-glutamyltransferase, aspartate aminotransferase, albumin, urate, and triglycerides were analyzed in 100 previously untreated female alcoholics. If used for screening, urate and triglycerides were found to be of no value, while various combinations of the other biochemical markers identified up to 75% of the patients.

Outcome of pregnancy in women treated at an alcohol clinic

The studies in man concerning foetal alcohol damage have mostly covered skid row female alcoholics, and no study has described the outcome of pregnancy of a larger group of women receiving inpatient care for alcoholism. In another study we have described the medical and social characteristics of such a group (n = 92) of women, as well as those of an age-matched control group. This article reports retrospectively on the pregnancies and the infants of these women. The pregnancies and deliveries were normal in both groups. There was no significant difference in rate of stillbirths, neonatal mortality, perinatal asphyxia or neonatal distress. In infants born to alcoholic mothers after established regular alcohol consumption (n = 31), a significant reduction of mean placental weight, birth weight, length at birth and head circumference at birth, was found compared with control infants (n = 170). In the former group 12.9% of the infants were small for gestational age, in the latter 1.3%. Congenital malformations were significantly increased in the former group. Thus, in female inpatients at an alcohol clinic a history of increased risk for adverse neonatal outcome was found.

Alcoholic women in fertile age treated at an alcohol clinic

The consumption of alcohol by women in Sweden is strongly increasing, especially in younger individuals. Since the rediscovery of the teratological properties of alcohol most of the studies concerning foetal alcohol damage in man have covered female skid row alcoholics. This investigation describes the medical and social characteristics of a group of women (n = 92) receiving inpatient care for alcoholism compared with an age-matched control group, in relation to obstetrical history. The conditions in the control group were in accord with those of the general population. Social problems and degree of alcoholism were noticeably advanced among the probands. The proband women who gave birth after established regular alcohol consumption were younger, showed more psychiatric complications during the treatment period, had started drinking and developing signs of advanced alcoholism earlier in life compared with probands who gave birth before established regular alcohol consumption. They also exhibited more social disturbances. The social problems caused by the mothers' alcohol abuse are expected to aggravate the biological consequences to their children.

Female alcoholics. V. Morbidity

Data from the public health insurance societies regarding 66 female alcoholics, hospitalized for the first time for alcoholism at the Department of Alcohol Diseases, Karolinska Hospital, Stockholm, were studied, and the developmental pattern of morbidity was compared with that of 68 male alcoholics fulfilling the same criteria. The observation period was 15 years. The progress of the alcoholism was not reflected in data from the social insurance societies up to the time of the first clinical treatment. However, the morbidity increased in both sexes after the treatment period, with higher disability, severity, and frequency rates, a large number of persons with disability pensions and increasing social stigmatization. The proportion of women granted disability pensions increased to significantly higher values than that of men, and that of women in the general population. The women had significantly fewer registrations in social registers than the men during the whole period. Women and older patients had higher disability rates, more sick-days due to "mental diseases" and a higher severity rate before admission. All differences were equalized in the last part of the study.

Female alcoholics. IV. Marital situation and husbands

Little research on the husbands of alcoholic women has been reported. A few studies have shown that they often are alcoholics or are suffering from other psychiatric diseases. The present study describes 51 men, married to female alcoholics, as regards alcoholism, other psycho-social disturbances and mortality, and accounts for the marital situation after an observation period of 6-12 years. A comparison is made with a control group of married male alcoholics. About 50% of the husbands were shown to be alcoholics, 14% had been treated for psychiatric diseases and more than 10% were disabled due to somatic diseases. At the end of the observation period, one-third of both patient groups were still married, one half of the male and one-third of the female patients were divorced. Twenty per cent of the marriages among the male patients and 35% of those among the female patients had been terminated by death. Ten female alcoholics and 14 husbands died, which is a significant excess mortality for both sexes. Mortality among the husbands was higher than expected due to cirrhosis of the liver and diseases of the circulatory system.

Female alcoholics. III. Development and pattern of problem drinking

The study provides a social and psychiatric description of development, drinking pattern and concomitant psychiatric disturbances of 100 female alcoholics, admitted to the Department of Alcohol Disease, Karolinska Hospital in Stockholm between 1963 and 1969. Comparisons are made between this group of women and 100 men of the same age, who were admitted during the same period. The criteria for selection were: 1) at least 7 days of in-patient treatment; 2) early cases. The subjects were between 20 and 65 years of age with a mean age of 40. It is shown that the women started drinking alcohol at higher ages than the men. The episodic use of alcohol passed into regular use, which progressed into misuse at significantly higher ages. The duration of the development from the onset to an alcoholic drinking pattern was significantly shorter and so was the duration of abuse at the time of admission. Notably more women than men showed a lonely drinking pattern and cited a specific external cause problem drinking. The women reported more nervous symptoms both in the growing ages and at admission, had received more psychiatric treatment both during childhood and in later life, and showed symptoms of other psychiatric disturbances in combination with alcoholism to a significantly higher degree than the men. Family history of alcoholism showed no differences between men and women, but the incidence of psychiatric illness was considerably higher for the first-degree relatives of the females.

Alcoholic females. II. Causes of death with reference to sex difference

The aim of this study has been to explore and compare the mortality of 100 female and 100 male alcoholics, admitted to a department of alcoholic diseases in 1963-69. The patients were early cases and mortality was studied during an observation period of 6-12 years. A total of 18 women and 16 men died. As compared with the general population, mortality was 5.6 and 3.0 times higher than expected for the women and men, respectively. Among the women a significant excess mortality was found for accidents, suicides, diseases of the respiratory system, and especially cirrhosis of the liver. Mortality among the men was significantly higher than expected due to suicides, diseases of the circulatory system, neoplasms, chronic alcoholism, and acute alcohol poisoning. The excess mortality from suicides found for both sexes was highest in the female group. Despite the hitherto rather small number of deaths in the two groups, the high frequency of cirrhosis of the liver among the women is striking.

Female alcoholics. I. Ways of admission of the alcoholic patient. A study special reference to the alcoholic female

The aim of this study has been to describe the different ways in which 100 alcoholics of each sex sought treatment, with special reference to the females. In addition, some psychiatric and social characteristics of the two groups of patients are presented. A significantly higher number of the females were admitted as a result of an acute complication: unconsciousness, suicide attempt, confusion, neurological disorders, etc., while the males generally sought treatment under less dramatic circumstances. As the patients selected were early cases, most had not been treated before, but in those with previous in-patient psychiatric treatment a diagnosis without an alcohol connection was significantly more common among the women. Drug abuse was considerably more frequent among the female as compared with the male alcoholics, and the specific lonely drinking pattern was also more common among the women. A striking difference between the sexes appeared with respect to partner: more than one-half of the married women had alcoholic husbands. The corresponding figure for the married men amounted to about 10%.
