Eighteen-month follow-up data on a treatment program for homeless substance abusing mothers.

In response to the dearth of data on substance abuse treatment among homeless mothers, this study breaks new ground in presenting 18-month follow-up data on 149 homeless mothers with young children enlisted in a substance abuse treatment program. The effects of residential compared to nonresidential services were evaluated over the follow-up period. Although dropout rates were high, predictors of dropout were identified, and the residential had a lower dropout rate compared to the nonresidential comparison group.

Not all homeless women are alike: effects of motherhood and the presence of children.

Previous work suggests that the population of homeless women is a heterogeneous group, and that motherhood and the presence or absence of children define sub-groups that may be distinct. The current study is a systematic study of 300 homeless women (90% of whom were mothers) according to these suggested sub-groupings. Mothers whose children were with them, compared to other women, were younger and often unemployed and welfare dependent.

Comparison of white and nonwhite homeless men and women.

The majority of the homeless population are people of color. There has been little study of racial differences among the homeless population, and racial findings have not been reported separately for homeless men and women. This study investigated differences between white and nonwhite homeless people in a randomly selected sample of 600 homeless men and 300 homeless women in St.

Molecular flexibility demonstrated by paramagnetic enhancements of nuclear relaxation. Application to alamethicin: a voltage-gated peptide channel.

A nitroxide spin label attached to the C-terminus of the channel forming peptide alamethicin produces an enhancement of the nuclear spin-lattice relaxation rates of peptide protons as a result of both intermolecular and intramolecular magnetic dipole-dipole interactions. The intermolecular contribution provides evidence that alamethicin monomers collide preferentially in a C-terminal-to-N-terminal configuration in methanol. From the intramolecular paramagnetic enhancement of nuclear spin-lattice relaxation times, effective distances between the unpaired electron on the nitroxide at the C-terminus of alamethicin and protons along the peptide backbone were calculated.

Prevalence of human T cell lymphotropic virus type II in American Indian populations of the southwestern United States.

We investigated the seroprevalence of human T cell lymphotropic virus type II (HTLV-II) using a screening enzyme-linked immunosorbent assay (ELISA) and immunoblot confirmation among the predominant tribes (Pueblo and Athapaskan) served by two large Indian Health Service facilities in New Mexico. Among persons being treated for sexually transmitted diseases, eight (3.2%) of 250 were seropositive for HTLV II, compared with eight (2.

A review of studies of psychiatric factors in Crohn's disease: etiologic implications.

Researchers have recently challenged long-held concepts of psychological origins to inflammatory bowel disease, in particular with ulcerative colitis. The purpose of this paper is to review published studies on psychiatric factors in Crohn's disease to determine whether available evidence points to the absence or presence of a significant relationship between Crohn's disease and stressful life events or psychiatric symptoms or disorders. Twelve articles with > or = 10 subjects on which statistical data were reported from standardized instruments of measure were found.

Access to psychiatric services for homeless mentally ill people.

This article looks at the problems of access to psychiatric services for homeless mentally ill people. Many such individuals are forced to use accident and emergency departments as their only source of psychiatric help.

Posttraumatic stress disorder in survivors of a mass shooting.

Objective: Posttraumatic stress disorder (PTSD) has been best studied among combat veterans. Less is known about PTSD among civilian populations exposed to traumatic events. A recent mass murder spree by a gunman in a cafeteria in Killeen, Tex.

Violence and the homeless: an epidemiologic study of victimization and aggression.

The present study is a random, systematic study of 900 homeless subjects in St. Louis that describes violence in their lives, both in terms of victimization, by specific violent traumatic events, and victimizing with recognized aggressive behaviors. Many subjects had experienced a traumatic event, and post-traumatic stress disorder was very common.

A comparison of homeless men and women: different populations, different needs.

Homeless women are very different from homeless men, but few studies have reported data separately on them or compared them directly with men. This report on a study of 600 homeless men and 300 homeless women in St. Louis presents comparison data on these populations.

Risk factors for cervical dysplasia in southwestern American Indian women: a pilot study.

Cervical cancer and cervical dysplasia occur at high rates among American Indian women in the southwestern United States. Few published data, however, have addressed risk factors for the development of cervical neoplasia among southwestern American Indian women. To investigate risk factors for cervical dysplasia in this population, we carried out a case-control pilot study focused on the effects of sexually transmitted diseases, sexual behavior, hygienic practices, cigarette use, contraceptive techniques, and diet in the development of cervical dysplasia.

A systematic study of mental health services utilization by homeless men and women.

Psychiatric illness is overrepresented among the homeless, but mental health services are underutilized in this population in proportion to their needs. The current study was concerned with 900 homeless men and women randomly sampled and systematically interviewed with the Diagnostic Interview Schedule; it focuses on psychiatric and substance abuse rehabilitation service patterns and stated needs of this population in relation to specific psychiatric disorders. Although rates of lifetime treatment utilization were fairly high in comparison with general population utilization patterns, rates of treatment in the current year were low.

Is antisocial personality a valid diagnosis among the homeless?

Objective: It has been argued that among the homeless many of the features of antisocial personality may be artifacts of homelessness and that strict application of the diagnostic criteria may be insensitive to social and cultural factors in this group. The authors studied a large group of homeless men and women to investigate the appropriateness of the diagnosis of antisocial personality disorder among the homeless.

Method: Six hundred homeless men and 300 homeless women were randomly selected from shelters and street locations in St.

Alcohol, drugs, and psychiatric comorbidity among homeless women: an epidemiologic study.

Background: Very little is known about the mental health of homeless women. The present study is one of the first to focus on psychiatric diagnosis and comorbidity in a population of homeless women systematically interviewed with a structured instrument.

Method: Three hundred homeless women randomly selected from St.

Multiple personality disorder: scientific and medicolegal issues.

Despite the intense study it has received since its inclusion in DSM-III, multiple personality disorder (MPD) largely remains an unvalidated construct. Definitional problems remain (there is not even agreement in the field as to whether a diagnosis of MPD truly means the existence of more than one personality), while the vagueness and liberality of existing criteria give the clinician little guidance in diagnosis. In forensic settings, diagnosis of MPD is even more problematic, since there is substantial evidence that the disorder cannot currently be phenomenologically distinguished from malingering.

Posttraumatic stress disorder among homeless men and women.

Six hundred homeless men and 300 homeless women in St. Louis were systematically interviewed using the revised Diagnostic Interview Schedule that includes a module for assessment of posttraumatic stress disorder (PTSD). Most subjects with PTSD had an additional life-time psychiatric diagnosis.

Estimating the prevalence of chronic fatigue syndrome and associated symptoms in the community.

Chronic fatigue syndrome is a poorly understood disease characterized by debilitating fatigue and neuromuscular and neuropsychological symptoms. Despite numerous studies on the subject, the epidemiology of the syndrome in the community remains largely unexplored. An estimate of the prevalence in the population is presented, approximating the Centers for Disease Control criteria as well as the prevalence estimates of the fatigue symptom complex that include fatigue, disability, and neuromuscular and neuropsychological symptoms.

Thanatology: a new clinical specialty to help confront death.

The complexities, widespread ramifications and uncertainties surrounding decisions dealing with the process of dying call for a specialty of clinical thanatology. The need for such a specialty grows out of medical technological progress, which has permitted the prolongation of life without parallel guidelines for its termination. The further functions and roles of a thanatologist would evolve with the passage of time.

Dietary micronutrients and cervical dysplasia in southwestern American Indian women.

American Indian women in the Southwest have high rates of cervical cancer and cervical dysplasia in contrast to low rates of cancers for other sites. Despite their high rates of cervical disease, no published information has specifically examined risk factors for cervical cancer or cervical dysplasia among American Indian women. We carried out a pilot case-control study of cervical dysplasia in southwestern American Indian women to examine the relationship of dietary intake of vitamin C, folacin, vitamin E, carotenoids, and retinol with cervical cytological abnormalities.

Do life events or depression exacerbate inflammatory bowel disease? A prospective study.

Objective: To determine whether depressed mood or life events are associated with an exacerbation of inflammatory bowel disease.

Design: A prospective study of a consecutive sample of patients with relapsing inflammatory bowel disease, followed by monthly questionnaires and periodic office visits.

Setting: A referral-based gastroenterology clinic at a medical school.

Post-traumatic stress disorder in disaster survivors.

In spite of the difficulties inherent in the study of traumatic stress in disaster victims, the benefit of obtaining more knowledge on the subject is potentially great, especially considering the numbers of individuals affected. Recent estimates of the frequency of world-wide traumatic events have determined that almost two million households annually experience damages and/or injuries from fire, floods, hurricanes, tornadoes, and earthquakes alone. The population that is at risk is expected to grow exponentially with our expanding technology, making it even more vital to acquire knowledge to help the growing number of future disaster victims.
