Abnormal asymmetry in language association cortex in autism.

Autism is a neurodevelopmental disorder affecting cognitive, language, and social functioning. Although language and social communication abnormalities are characteristic, prior structural imaging studies have not examined language-related cortex in autistic and control subjects. Subjects included 16 boys with autism (aged 7-11 years), with nonverbal IQ greater than 80, and 15 age- and handedness-matched controls. Magnetic resonance brain images were segmented into gray and white matter; cerebral cortex was parcellated into 48 gyral-based divisions per hemisphere. Asymmetry was assessed a priori in language-related inferior lateral frontal and posterior superior temporal regions and assessed post hoc in all regions to determine specificity of asymmetry abnormalities. Boys with autism had significant asymmetry reversal in frontal language-related cortex: 27% larger on the right in autism and 17% larger on the left in controls. Only one additional region had significant asymmetry differences on post hoc analysis: posterior temporal fusiform gyrus (more left-sided in autism), whereas adjacent fusiform gyrus and temporooccipital inferior temporal gyrus both approached significance (more right-sided in autism). These inferior temporal regions are involved in visual face processing. In boys with autism, language and social/face processing-related regions displayed abnormal asymmetry. These structural abnormalities may relate to language and social disturbances observed in autism.

Systemic juvenile rheumatoid arthritis: cognitive function and social adjustment.

In contrast with other systemic rheumatic diseases in childhood, no systematic studies exist that focus on possible long-term risks for central nervous system involvement in systemic juvenile rheumatoid arthritis (SJRA). We investigated 31 children and adolescents with SJRA, aged 6 to 24 years (mean, 12.5 years; standard deviation, 4.3 years), with mean disease duration of 6.2 years (standard deviation, 3.5 years; range, 0.6-14 years) for their cognitive and fine motor abilities. We also examined 31 matched healthy control subjects. In addition, parents assessed social activities and social and emotional problems in their children. Patients and control subjects performed within normal limits of intelligence quotient, memory and learning, attention, and fine motor scores. Less social activities were reported for patients. Patients and control subjects, however, had normal social and emotional problem scores. SJRA, although a burdensome chronic disease, is not associated with cognitive impairment or increased social and emotional problems. Cognitive performance and social adjustment of young patients with SJRA are not affected by disease activity and duration.

Reproductive biology of captive male cottontop tamarin monkeys as a function of social environment.

The cottontop tamarin, Saguinus oedipus oedipus, is a cooperatively breeding monkey in which mature male and female offspring serve as helpers to assist in rearing younger siblings. Generally, only one female per social group reproduces; breeding restriction is mediated in postpubertal female offspring through low and acyclic levels of reproductive hormones. We investigated (1) reproductive activity of postpubertal male offspring, and (2) whether aggression towards male offspring and a cortisol-mediated stress response might restrict breeding of male offspring in the natal group. We examined sexual behaviour, olfactory communication and urinary hormone levels (testosterone, dihydrotestosterone, luteinizing hormone, cortisol) of the subject males while we manipulated their social environment from housing in natal groups to pairing with a novel female, and after the production of their own offspring. Mounting and erection rates of the male subjects were as high in the natal group as when paired with a novel female. However, most mounts in the natal group were directed towards other males, and complete copulation sequences did not occur with natal-group females. Social environment had no significant effect on olfactory investigation of breeding females. Although hormone levels increased significantly after the subjects were removed from the natal group, the elevation was transient; the hormone levels of subjects in their natal groups did not differ from the levels shown by the same males when successfully producing their own offspring. Male offspring received more contact aggression in the natal group than when paired with the novel female. However, most of the aggression was received from siblings rather than the breeding pair, and levels of cortisol did not correspond with levels of aggression. Thus, at both a behavioural and endocrine level, mature male offspring in captive natal groups were potentially fertile, but sexual activity with natal-group females appeared to be behaviourally restricted and directed instead towards group males. In wild cottontop tamarin groups, this reproductive potential may allow male helpers flexibility to respond to breeding opportunities.

Quality of life of women with ovarian cancer.

The primary objectives of this study were to determine the nature and extent of physical problems and psychological distress experienced by women with ovarian cancer and to identify medical and sociodemographic factors that were predictive of distress. Quality of life was assessed at 3-month intervals, for a maximum of 12 months in 151 ovarian cancer patients, most with advanced-stage disease (86%). Patients' pain, other physical symptoms, level of physical functioning, psychological state, and social functioning were evaluated using the following measures: a detailed pain questionnaire, Memorial Pain Assessment Card, Memorial Symptom Assessment Scale, Mental Health Inventory (MHI), Functional Living Index--Cancer (FLIC), and the Karnofsky Performance Status. Upon entry, 33% of patients reported significant psychological distress, as indicated by MHI Psychological Distress scores (MHI-PD) equal or greater to 1.5 standard deviations above the mean of a nationwide community sample. Impaired physical functioning (FLIC subscale) was the most important predictor of heightened psychological distress (MHI-PD) at baseline (1.5 SD or greater above the norm) (P = 0.0004) in a stepwise logistic regression involving medical/physical and sociodemographic variables as predictors. Further, significant differences were found in all quality of life scales between patients with Karnofsky Performance Status scores of < or = 80, and those with ratings of 90 or greater (P = 0.036 to P < 0.0001). These data suggest the need for an improved and more frequent assessment of ovarian cancer patients' psychological status, particularly as physical functioning declines, to improve early detection and referral to treatment of those suffering from psychiatric sequelae of cancer.

Craniosynostosis as a risk factor.

Craniosynostosis is a little known organic factor in sociopathy. This factor should be among those taken into consideration in selecting patients to undergo craniotomy. Among 22,000 skulls of neuropsychiatric patients, there were 100 with premature coronal synostosis, compared with 57 with dolichocephaly. Thirty-seven of the 100 patients with coronal synostosis exhibited disorders of social adaptation; frontal cortex functions are assumed to be involved. There were 34 cases of mental deficiency, 21 cases of psychosis, 13 of cerebral vascular disease, 10 cases of epilepsy, 4 of acrocephalosyndactyly, 3 of decompensation by slight craniocerebral trauma, and 1 case of ependymoma of the IV ventricle. Dolichocephalic patients exhibited a stronger tendency towards depressive states and cerebral vascular disease. The risks of cosmetic impairment and resulting psychosocial problems are discussed; especially in girls with oxy- and scaphocephaly craniofacial correction, is indicated, as it is also in patients with Saethre-Chotzen syndrome. In cases of premature synostosis of the coronal suture or synostosis of several sutures for carrying out a craniotomy, it is advisable to employ a combination of orbito-frontosphenoidal osteotomy for extension of the anterior cranial fossa. Craniosynostosis is a risk factor which, depending on the individual case and the sex and age of the patient, can impair central nervous functions, social adaption, and the blood supply of the brain.

The health-related functions of social support.

Social support research has been hampered by a lack of clarity both in the definitions of social support and in the conceptualization of its effects on health outcomes. The present study compared social network size and three types of perceived social support--tangible, emotional, and informational--in relation to stressful life events, psychological symptoms and morale, and physical health status in a sample of 100 persons 45-64 years old. Social network size was empirically separable from, though correlated with, perceived social support and had a weaker overall relationship to outcomes than did support. Low tangible support and emotional support, in addition to certain life events, were independently related to depression and negative morale; informational support was associated with positive morale. Neither social support nor stressful life events were associated with physical health. It was concluded that social support research would benefit from attention to the multidimensionality of support and greater specificity in hypotheses about the relationship between types of support and adaptational outcomes.

The structure and function of social support networks in families with handicapped children.

Three structural characteristics of social support networks (size, density, and boundary density) and two relationship characteristics (reciprocity and dimensionality) were assessed in a sample of 56 families with a child with spina bifida and 53 matched comparison families. The results indicate that social networks of families with handicapped children tended to be smaller than the networks of comparison families, particularly with regard to mothers' total and friendship networks. The networks of families with handicapped children were more dense as well. As predicted, there was greater boundary density in spousal networks in families with handicapped children. Differences in network reciprocity were inconclusive while the results indicate that families with handicapped children tended to rely more heavily upon multidimensional network contacts than did comparison families. The results are discussed in light of our understanding of stress, social support, and the social ecological context of families.

Long-term efficacy of dynamic graciloplasty for fecal incontinence.

PURPOSE: Patients with end-stage fecal incontinence in whom all standard medical and surgical treatment has failed or is not expected to be effective can be treated by dynamic graciloplasty. The aim of this study was to review the long-term efficacy data. METHODS: Success was defined as a greater than 50 percent decrease in the frequency of incontinent episodes. Measured physiologic parameters included enema retention time and the difference in resting and squeezing pressures with and without stimulation. Measured quality-of-life parameters included the Medical Outcomes Study Short Form 36 Health Status Questionnaire, a Fecal Incontinence TyPE Specification, the Zung Self-Rating Depression Scale, the "state" portion of the State-Trait Anxiety Inventory, and the Visual Analog Scale, which were administered at baseline and through follow-up. Independent monitors collected data as part of a multicenter trial for patients who underwent dynamic graciloplasty from May 1993 to November 1999. RESULTS: There were 129 patients entered in the study, 115 of whom met eligibility criteria and were included in the efficacy outcome analysis. Twenty-seven patients entered the study with a preexisting functioning stoma; the remaining 88 patients did not have a functioning stoma at the time of enrollment. Success was achieved in 62 percent of nonstoma patients at 12 months; these results were sustained at 18-month and 24-month follow-up assessments (55 and 56 percent, respectively). The success rate in the stoma patients increased from 37.5 percent (9 of 24 patients) at 12 months to 62 percent (13 of 21 patients) at 18 months and was 43 percent at 24 months (9 of 21 patients), which reflects the increased number of patients whose stomas were closed. Although the measured physiologic continence parameters generally improved, these changes did not correlate with continence outcome. The group of patients (stoma and nonstoma) who underwent dynamic graciloplasty showed statistically significant improvements in quality of life as measured by Medical Outcomes Study Short Form 36 physical function (P = 0.006) and social functioning (P = 0.02) assessment. CONCLUSIONS: Dynamic graciloplasty was successful in the majority of patients with end-stage fecal incontinence. This result was usually achieved by 12 months after surgery in patients who did not have stomas and by 18 months in patients who had stomas at the time of dynamic graciloplasty surgery. These various improvements conferred by dynamic graciloplasty persisted during the two-year follow-up.

Localized and discrete changes in neuropeptide (LHRH and TRH) and neurotransmitter (NE and DA) concentrations within the olfactory bulbs of male mice as a function of social interaction.

Individually housed male mice were exposed to either an intact male or an ovariectomized female mouse for 1 min and decapitated at 5, 15, or 60 min to examine the hypothesis whether discrete changes in olfactory bulb neuropeptide (LHRH and TRH) and neurotransmitter (NE and DA) concentrations would occur following onset of exposure. A nonexposed control group (decapitated at time 0) was also included. Bilateral olfactory bulbs were dissected into anterior dorsal (ADOB) and posterior dorsal (PDOB) olfactory bulb fragments and prepared for radioimmunoassays (LHRH and TRH) or radioenzymatic assays (NE and DA). Concentrations of LHRH and NE, but not of TRH and DA, from the PDOB were significantly greater than those of ADOB fragments. Exposure to a male resulted in a significant increase of PDOB LHRH at 5 min following exposure and a significant increase in LHRH at 15 min following female exposure. Norepinephrine within the ADOB and PDOB and DA within the PDOB demonstrated a statistically significant increase at 60 min following exposure to an ovariectomized female. In marked contrast, no statistically significant changes were obtained following male exposure. These results not only demonstrate a preferential localization of neuroregulators within the olfactory bulb of male mice but discrete changes in the concentration of these neuroregulators in response to male or female exposure, suggesting the possibility that some processing and coding of chemical cue information during social encounters already occurs at the level of the olfactory bulb.

Genetic reduction of noradrenergic function alters social memory and reduces aggression in mice.

Aberrant social behavior is a hallmark of many cognitive, mood, and neurological disorders, although the specific molecular mechanisms underlying the behavioral deficits are not well understood. The neurotransmitter noradrenaline (NA) has been implicated in some of these disorders, as well as in several aspects of social behavior in humans and animals. We tested dopamine beta-hydroxylase knockout (Dbh -/-) mice that lack NA in various social behavior paradigms. Dbh -/- mice have relatively normal performance in the elevated plus maze, light/dark box, and open field test - three measures of anxiety - and a social recognition test. In contrast, Dbh -/- mice displayed a specific deficit in a social discrimination task and had a nearly complete absence of resident-intruder aggression. These results indicate that intact NA signaling is required for some types of social memory and aggression, but that a lack of NA does not greatly affect anxiety in mice. Further exploration of NA deficits in neurological disease may reveal mechanisms of aberrant social behavior.

Prevalence and impact on generic quality of life of urinary incontinence in Japanese working women: assessment by ICI questionnaire and SF-36 Health Survey.

OBJECTIVES: To examine the prevalence of urinary incontinence (UI) and the relationship between UI and generic quality of life (QOL) in working women. METHODS: Of 7229 female hospital nurses in Japan, 3734 (51.7%) responded to a self-administered postal questionnaire that included the Rand Medical Outcomes Study 36-item Health Survey (SF-36) and the International Consultation on Incontinence questionnaire (ICIQ) for evaluating symptoms and health-related QOL. RESULTS: The overall prevalence of UI in Japanese working women aged 20 to 64 years (mean 35.2) was 16.7%. The main type of incontinence was stress UI (73%). Its prevalence increased with age and reached a plateau at age 45 to 49 years (34.7%). The ICIQ score also correlated significantly with age. Generic QOL, especially physical functioning, role-physical, social functioning, and role-emotional, was significantly impaired by UI. A comparison of subjects with and without UI revealed that the differences in the physical and mental component summary scores of the SF-36 were largest in the age groups of 25 to 29 and 55 to 59 years, respectively. The correlations of the ICIQ score with the physical and mental component scores were most significant in the age groups of 25 to 29 and 45 to 49 years, respectively. The impact of mixed UI on QOL showed a greater tendency than that of stress or urge UI. CONCLUSIONS: The prevalence of UI showed an age-related increase, with a peak at 45 to 49 years old. The impact of UI on physical health was great in individuals in their 20s, but its impact on mental health increased in the older age groups.

A test of the structural model of initiation of dieting among adolescent girls.

This article reports alternative findings from a pilot study to those presented recently (Strong GF, Huon KG. J. Psychosom. Res., 1998; 44:315-326) in regard to the proposed model of sociopsychological processes involved in the initiation of dieting among young adolescent girls. One hundred thirteen female high school pupils completed a battery of questionnaires that assessed dieting status, dietary restraint, autonomous functioning, skill-related functioning, social influence, and family functioning. The results indicate that family functioning predicts dietary restraint but that this effect is mediated by peer influence to diet. Furthermore, family functioning was associated with autonomous functioning, suggesting that this relationship should be pursued in a future test of the model. This pattern of results is different from an earlier test of the model, which indicated only a parental influence on dieting status. The results confirm that peer influences should be retained as a causal factor in a reformulated structural model.
